ended June 30, 1998 are amended to read as follows:

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS


FORWARD LOOKING STATEMENTS

    The following Management's Discussion and Analysis of Financial Condition
and Results of Operations contains forward-looking statements, which involve
risks and uncertainties. The Company's actual results could differ materially
from those anticipated in these forward-looking statements as a result of
certain factors, including, without limitation, those risk factors set forth
under "Risk Factors that May Affect Future Results" included in this
Management's Discussion and Analysis of Financial Condition and Results of
Operations.

    The following discussion also should be read in conjunction with the
consolidated financial statements and notes thereto included in the Company's
Annual Report on Form 10-K for the year ended December 31, 1997, filed with the
Securities and Exchange Commission on March 31, 1998 and the Company's audited
supplemental consolidated financial statements and notes thereto included in the
Company's Current Report on Form 8-K as filed with the Securities and Exchange
Commission on May 15, 1998.

OVERVIEW

    The Company operates the Excite Network (which includes the Excite and
WebCrawler brands) and provides a gateway to the Web that organizes, aggregates
and delivers information to meet the needs of individual consumers. Excite,
Inc., formerly Architext Software, Inc., was formed in June 1994 and, from its
inception to September 1995, its operating activities related primarily to
recruiting personnel, raising capital, purchasing operating assets, providing
custom product development and consulting services. The Company first launched
its Excite search and directory service in October 1995. In April 1997, the
Company launched a channels-based format for its service and content on the
Excite brand to provide consumers with an interface that reflects the way they
navigate through other forms of media and enables advertisers to more
effectively reach target consumers. The Excite brand currently includes 18
channels of topical interest such as Entertainment, Sports and Money/Investing.
In September 1997, the Company launched a similar channels-based format for its
WebCrawler brand that currently includes 19 channels.

    Historically, advertising revenues have been derived principally from
short-term advertising contracts in which the Company guarantees a minimum
number of impressions (a view of an advertisement banner by a consumer) for a
fixed fee. Such banner advertising revenue is dependent upon both the number of
impressions and the rate per thousand impressions ("CPMs") charged. The Company
generally charges higher rates for advertisements focused on targeted groups,
either by key-word associations or affiliations with specific content, than for
general rotation advertisements on the Excite Network.

    During its limited operating history, the Company has experienced seasonal
fluctuations in the amount of banner advertisements purchased on its network,
with advertisers historically purchasing fewer advertisements in the first
calendar quarter of each year. Because the market for Web advertising is an
emerging market, additional seasonal patterns in Web advertising may develop in
the future as the market matures.

    In 1997, the Company began entering into longer-term advertising and
commerce sponsorship agreements. These agreements generally involve more
integration with the Excite Network and provide for more varied sources of
revenue to Excite over the term of the agreements, which average from two to
three years. Under these agreements, Excite earns fees for generating
impressions that in some instances are guaranteed. Sponsorship customers
accounted for approximately 24% and 27% of advertising revenues for 1997 and the
six months ended June 30, 1998, respectively. Revenues are generally recognized
ratably over the term of the agreement, provided that the Company does not have
any significant remaining obligations and collection of the resulting receivable
is probable. To the extent that impression deliveries are falling short of the
guarantees, the Company defers recognition of the corresponding revenues. A
number of these agreements also provide that revenues or gross margins from
advertising and electronic commerce transactions are to be shared between the
advertiser and Excite as realized. Revenues or margin sharing recognized from
such electronic commerce transactions were insignificant through the second
quarter of 1998, and are expected to be insignificant for the remainder of 1998.
The Company does not expect revenue growth relating to sponsorship advertising
revenues



                                        1

to continue at the current rate in future periods as availability of
exclusive sponsorships may be limited. See "Risk Factors that May Affect Future
Results -- Risks Related to Sponsorships" and " -- Risks Associated with Banner
Advertising."

In April 1998, the Company and Netscape entered into a two-year agreement (the
"Netcenter Agreement"), under which the Company will, among other things,
provide, host and sell advertising for certain Co-Branded Services for
Netscape's recently announced Netcenter Service (the "Co-Branded Services"). In
connection with the Netscape Agreement, the Company has paid to Netscape a total
of $70.0 million (the "Cash Payment"). Also in connection with the Netcenter
Agreement, the Company has issued to Netscape a warrant to purchase 846,158
shares of the Company's Common Stock at an exercise price of approximately
$29.55 per share (and "First Warrant") and a second warrant to purchase shares
of the Company's Common Stock at an aggregate exercise price of $10.0 million
(the "Second Warrant", together with the First Warrant, the "Warrants"). The
First Warrant is exercisable for a two year period commencing on April 30, 1998,
1998. The Second Warrant will be exercisable for a two year period commencing
April 30, 1999. The exercise price per share of Common Stock covered by the
Second Warrant will be determined by dividing $10 million by the average closing
price of the Company's Common Stock for the thirty (30) most recent trading days
ending on the third trading day preceding April 30, 1998. The fair value of the
first warrant and the aggregate $10.0 million exercise price of the second
warrant has been estimated to be $19.9 million. The Cash Payment and the value
assigned to the Warrants totaling $89.9 million were capitalized as Prepaid
Netscape Distribution Costs and Trademarks during the second quarter of 1998 and
will be amortized over the two-year term of the Netcenter Agreement. Under the
Netcenter Agreement, the Company will only recognize revenues generated from the
Co-Branded Services and not from any other part of Netcenter. A portion of the
revenues will be credited against the Company's revenue-sharing obligation to
Netscape until the Company recoups a specified amount of the Cash Payment.
Thereafter, the Company must pay Netscape a portion of additional revenues
generated from the Co-Branded Services. Unless Netscape generates impressions
significantly greater than the guaranteed amount as specified in the Agreement,
the increased revenues to the Company resulting from the co-branded services
under the Netcenter Agreement will not be sufficient to recover the combined
costs of the prepayment, the warrant value and the incremental operating costs
that will be incurred by the Company as a result of the Agreement. The Company
anticipates that it will incur expenses for the start-up and development of the
services contemplated in the Netcenter Agreement, including the costs of
personnel, content creation, facilities and depreciation of assets purchased for
the Netcenter Service. On this basis, the Company anticipates that the Netcenter
Agreement will serve to generate losses for the Company during its term. See
"Risk Factors that May Affect Future Results--Risks Related to Netcenter
Agreement."

    The Company has acquired a number of businesses, technologies, services,
product lines and content. In April 1998, the Company acquired Throw, a
developer of community products, issued approximately 330,000 shares of its
Common Stock, assumed options and warrants to purchase up to an aggregate of
approximately 318,000 shares of its Common Stock. Also in April 1998, the
Company acquired Classifieds2000, a provider of online classified ads. The
Company issued approximately 1,730,000 shares of its Common Stock to former
stockholders of Classifieds2000 and assumed options and warrants to purchase up
to approximately 50,000 shares of its Common Stock. In February 1998, the
Company acquired MatchLogic, a provider of solutions for the management and
optimization of Internet advertising campaigns. The Company issued approximately
6.1 million shares of its Common Stock to former stockholders of MatchLogic and
assumed options and warrants to purchase up to approximately 1,049,000 shares of
its Common Stock. The acquisition of MatchLogic and Classifieds2000 were
accounted for as a pooling of interests and the acquisition of Throw was
accounted for as a purchase.

        All financial information for dates and periods prior to the merger with
MatchLogic has been restated to reflect the combined operations of the Company
and MatchLogic. Financial information for dates and periods prior to the
acquisition of Classifieds2000 has not been restated to reflect the combined
operations of the Company and Classifieds2000, as Classifieds2000's results of
operations were not material to the Company's consolidated financial statements
in any historical period. See Note 2 and "Risk Factors that May Affect Future
Results--Acquisition Strategy; Integration of Past and Future Acquisitions."

    The Company has incurred significant operating losses since inception, and
as of June 30, 1998, the Company had an accumulated deficit of approximately
$131.5 million. Although the Company experienced significant revenue growth
during 1997 and the first half of 1998, there can be no assurance that this
growth rate will be sustained or that revenues will continue to grow or that
historical operating results will be indicative of future operating results. In
addition, as the Company has grown, its operating expenses have increased, and
the Company expects that its operating expenses will continue to increase as a
result of its acquisitions, the performance of its obligations under the
Netcenter Agreement, its increased sales and marketing efforts, its increased
funding for development activities and the increased general and administrative
staff needed to support the Company's growth. To the extent that revenues do not
grow at anticipated rates or 



                                       2
<PAGE>   4

that increases in such operating expenses precede or are not subsequently
followed by commensurate increases in revenues, or that the Company is unable to
adjust operating expense levels accordingly, the Company's business, results of
operations and financial condition will be materially and adversely affected.
There can be no assurance that in the future the Company will be profitable on a
quarterly or annual basis.

RESULTS OF OPERATIONS

REVENUES

    Revenues were $33.0 million for the second quarter of 1998, as compared to
$10.1 million for the second quarter of 1997, an increase of $22.9 million or
227%. For the first half of 1998 and 1997, revenues were $56.0 million and $17.6
million, respectively, an increase of $38.4 million or 218%. This increase in
both periods is primarily the result of an increase in the number of advertisers
purchasing advertising banners on the Company's Web sites, an increase in
sponsorship advertising revenue, and to a lesser extent, an increase in sales of
targeted advertisements with higher rates. Also contributing to the increase in
revenues was the increased revenues attributable to MatchLogic, which began
operations in May 1997. Revenues from international operations were not
significant during the three and six months ended June 30, 1998 and 1997.

    The Company expects to continue to derive a substantial amount of its total
revenues from selling advertisements. Because the market for advertising on the
Web is intensely competitive, advertising rates could be subject to pricing
pressures in the future. If the Company is forced to reduce its advertising
rates or experiences lower CPMs (price per thousand impressions) as a result of
such competition or otherwise, future revenues could be adversely affected.

COST OF REVENUES

    Cost of revenues consists primarily of: hosting costs; royalties and other
cost of revenues; and amortization of purchased technology. Hosting costs relate
to the maintenance and technical support of the Excite Network, and are
comprised principally of personnel costs, telecommunications costs, equipment
depreciation and overhead allocations. Royalties and other cost of revenues
include expenses related to royalties, license agreements and revenue sharing
agreements for content and other services such as email and chat room services.
For the second quarter and first half of 1997, the Company recognized
amortization of purchased technology of $1.9 million and $4.3 million,
respectively, related to the WebCrawler acquisition. There were no corresponding
costs for the comparable periods in 1998 as the cost of the technology was fully
amortized at December 31, 1997.

    Total cost of revenues increased in absolute dollars by $2.3 million to $6.5
million, or 20% of revenues for the second quarter of 1998, from $4.2 million,
or 41% of revenues for the comparable period in the prior year. For the current
year to date, total cost of revenues increased by $3.1 million to $12.1 million,
or 22% of revenues, from $9.0 million, or 51% of revenues for the comparable
period in the prior year. Hosting costs for the second quarter of 1998 increased
in absolute dollars by $2.0 million to $3.7 million, or 11% of revenues, from
$1.7 million, or 17% of revenues for the comparable period in the prior year.
For the current year to date, hosting costs increased by $2.9 million to $6.5
million, or 12% of revenues, from $3.5 million, or 20% of revenues for the
comparable period in the prior year. The increase in hosting costs is due
primarily to increased personnel expenses and equipment costs relating to
maintaining and supporting the Company's Web sites and services. Royalties and
other cost of revenues increased in absolute dollars by $2.2 million to $2.8
million, or 8% of revenues, for the second quarter 1998 from $556,000, or 6% of
revenues for the comparable period in the prior year. For the current year to
date, royalties and other cost of revenues increased by $4.5 million to $5.6
million, or 10% of revenues, from $1.1 million, or 6% of revenues for the
comparable period in the prior year. The increase in royalties and other cost of
revenues was primarily due to increased royalties and margin sharing payments
from revenue sharing agreements.

    Excluding amortization of purchased technology, total cost of revenues
increased by $4.2 million to $6.5 million, or 20% of revenues for the second
quarter of 1998, from $2.2 million, or 22% of revenues for the comparable period
in the prior year. Excluding amortization of purchased technology, total cost of
revenues for the first half of 1998 increased by $7.4 million to $12.1 million,
or 22% of revenues from $4.6 million, or 26% of revenues for the comparable
period in the prior year.



                                       3
<PAGE>   5

    Excluding amortization, cost of revenues in future periods is expected to
increase in absolute dollars and may increase as a percentage of revenues as the
Company increases costs to support expanded services and content. The Company
also expects to experience increased hosting costs in connection with performing
its obligations under the Netcenter Agreement and to experience increased
royalties and other cost of revenues as a result of the revenue sharing
provisions of the Netcenter Agreement.

GROSS PROFIT

    Gross profit increased by $20.6 million or 349% to $26.5 million or 80% of
revenues for the second quarter of 1998, from $5.9 million or 59% of revenue for
the comparable period in the prior year. For the first half of 1998, gross
profit increased by $35.3 million or 409% to $44.0 million or 78% of revenues,
from $8.6 million or 49% of revenue for the comparable period in 1997. The
increase in gross profit in absolute dollars and as a percentage of revenues was
primarily due to the fact that revenues grew at a faster rate than hosting costs
and royalties and other cost of revenues, a favorable product mix, and the
elimination of amortization of purchased technology discussed above. In the
future, gross profit may be affected by the types of advertisements sold and
revenue sharing provisions of distribution and content agreements. These items
have negatively affected gross profit in the past and may continue to negatively
affect it in the future. Furthermore, pursuant to the provisions of certain
agreements with operators of Web access points and with content providers, the
Company shares advertising revenues based upon the number of consumers directed
to its network. A low level of targeted advertising as a percentage of total
advertising sold, a decrease in targeted or mass Web advertising rates or an
increase in the Company's advertising revenue sharing obligations could
adversely affect gross margins in the future.

Operating Expenses

        Research and Development. Research and development expenses consist
principally of engineering and editorial personnel costs, equipment
depreciation, consulting fees, supplies and allocation of overhead. Research and
development expenses for the second quarter of 1998 increased to $7.3 million,
or 22% of revenues, from $3.6 million, or 36% of revenues in the comparable
period of the prior year. Research and development expenses for the first six
months of 1998 increased to $13.2 million, or 24% or revenues, from $6.7
million, or 38% of revenues in the comparable period of the prior year. The
increase in absolute dollars was primarily attributable to increased expenses as
a result of the Classifieds2000 and Throw acquisitions, as well as an increase
in engineering and editorial headcount to support the Company's channels format
and personalization capabilities for the Excite Network. The Company believes
that a significant level of research and development expense is required to
remain competitive and, accordingly, the Company anticipates that it will
continue to devote substantial resources to research and development and that
these costs will increase in absolute dollars in future periods. The Company
also expects to continue to experience increased research and development
expenses in order to integrate acquired technologies and provide programming and
content for the Co-Branded Services of Netcenter.

    Sales and Marketing. Sales and marketing expenses consist principally of
sales and marketing personnel costs, agency and consulting fees, commissions,
promotional and advertising expenses and allocation of overhead. Sales and
marketing expenses for the second quarter of 1998 increased to $14.9 million, or
45% of revenues, from $7.2 million, or 71% of revenues, in the comparable period
of the prior year. For the current year to date, sales and marketing expenses
increased to $25.0 million, or 45% of revenues, from $13.5 million, or 77% of
revenues in the comparable period for the prior year. The increase in absolute
dollars was primarily due to the hiring of additional sales and marketing
personnel and increased expenses resulting from the acquisition of Classifieds
and Throw. Promotional expenses remained relatively constant in the second
quarter and first half of 1998, as compared to the same period of the prior year
as the prior year period included costs associated with a national media
campaign that started in the fourth quarter of 1996. The Company expects to
continue to incur significant promotional and advertising expenses and
anticipates that these costs will increase in absolute dollars in future periods
as the Company promotes its brands and introduces new services in order to
create and maintain brand loyalty among customers. The Company also expects to
continue to experience increased sales and marketing expenses as it is
responsible for all advertising sales on the Co-Branded Services of Netcenter.



                                       4
<PAGE>   6

    Distribution License Fees and Data Acquisition Costs. Distribution license
fees and data acquisition costs consist principally of fees paid to third-party
Internet companies such as Netscape to provide entry points to the Excite
Network and costs to update and maintain the ad targeting and tracking database
which is continually being updated by the Company's MatchLogic subsidiary.
Distribution license fees and data acquisition costs were $5.2 million for the
second quarter of 1998, as compared to $1.7 million for the comparable period in
1997. For the current year to date, distribution license fees and data
acquisition costs were $9.2 million, compared to $1.7 million for the comparable
period in the prior year. The 1998 costs included distribution license fees
related to agreements entered into with Netscape in March 1997 as well as data
acquisition costs incurred by MatchLogic during the period. In addition, a total
of $855,000 was amortized to Distribution License Fees and Data
Acquisition Costs relating to the April 1998 Netcenter Agreement.

    In the future, high traffic Web sites, Internet service providers, providers
of Web browsers or other distribution channels could require cash payments or
other types of consideration as compensation for listing or promoting the Excite
Network, which could result in increased distribution license fees. See "Risk
Factors that May Affect Future Results--Risks Related to Netcenter Agreement."

    General and Administrative. General and administrative expenses consist
principally of administrative and executive personnel costs, provision for
doubtful accounts, fees for professional services and allocation of overhead.
General and administrative expenses for the second quarter of 1998 increased to
$3.9 million, or 12% of revenues, from $1.8 million, or 18% of revenues, in the
comparable period of the prior year. General and administrative expenses for the
first half of 1998 increased to $6.7 million, or 12% of revenues, from $3.1
million, or 18% of revenues, in the comparable period of the prior year. The
increase in absolute dollars is primarily due to increased personnel costs to
support the expansion and infrastructure of the Company's operations and global
business strategy. In particular, the acquisition of Classifieds2000 and the
growth in the Company's finance and administrative departments contributed to
this increase. The Company anticipates that its general and administrative
expenses will continue to increase in absolute dollars as the Company expands
its administrative and executive staff, adds infrastructure and assimilates
acquisitions of acquired technologies and businesses. In addition, the Company
plans to continue to run MatchLogic as an independent subsidiary with its own
administrative function.

    In-Process Technology. During the first half of 1998 and 1997, the Company
incurred charges for in-process technology of $16.2 million and $2.3 million,
respectively. The Company acquired Throw in April 1998, accounted for the
transaction as a purchase, and of the total purchase price, $16.2 million was
allocated to in-process technology and charged to operations in the second
quarter of 1998. The 1997 charge of $2.3 million related to the value of
acquired in-process technology that had not reached technological feasibility at
the time of MatchLogic's formation in May 1997. To determine the value of the
in-process technology, the Company considered, among other factors, the state of
development of each project, the time and cost needed to complete each project,
expected income, and associated risks which included the inherent difficulties
and uncertainties in completing the project and thereby achieving technological
feasibility and risks related to the viability of and potential changes to
future target markets. This analysis results in amounts assigned to in-process
research and development projects that had not yet reached technological
feasibility and does not have alternative future uses.

    Other Merger and Acquisition Related Costs, including Amortization of
Goodwill and Other Intangible Assets. During the second quarter of 1998 and
1997, the Company incurred merger and acquisition related costs of $1.2 million
and $463,000, respectively. During the first half of 1998 and 1997, the Company
incurred merger and acquisition related costs of $2.1 million and $1.4 million,
respectively. In 1998, the Company incurred charges of approximately $743,000
and $700,000 for the acquisition of Classifieds2000 and MatchLogic,
respectively. The remainder of the merger and acquisition related costs for the
first half of 1998 and all of the costs for the comparable period of the prior
year related to the amortization of goodwill and other purchased intangibles
resulting primarily from the WebCrawler acquisition.

    Amortization of Prepaid Netscape Service. The 1998 costs included a $2.5
million charge related to the amortization of the Prepaid Netscape Service
associated with the April 1998 Netcenter Agreement. The Company anticipates
incurring a total amortization charge of approximately $7.6 million per quarter
relating to the Netcenter Agreement for the duration of the Agreement.



                                       5
<PAGE>   7

    Net Interest Expense and Other. Net interest expense and other increased to
$649,000 for the second quarter of 1998, compared to $112,000 for the comparable
period of the prior year. Current year to date, net interest expense and other
increased to $843,000 compared to $1,000 for the comparable period of the prior
year. This increase in net interest expense and other was due primarily to an
increase in interest expense resulting from the $50 million note payable due to
Intuit, as well as additional capital lease obligations, non-lease financing
obligations and the convertible note issued to Itochu Corporation. The overall
increase in net interest expense and other was partially offset by an increase
in interest income earned on cash received in June 1998 from the Company's
public offering, which was used to fund operations and its obligations under the
Netcenter Agreement.

    Equity Share of Losses of Affiliated Company. In October 1997, the Company
and Itochu Corporation and certain affiliated entities (collectively "Itochu")
entered into a joint venture agreement with respect to the Company's
wholly-owned subsidiary, Excite Japan, in order to provide Web-based information
services to the Japanese market. The Company currently holds, and intends to
retain, a 50% equity interest in Excite Japan. For the three and six months
ended June 30, 1998, Excite's share of the losses of Excite Japan was $551,000
and $1.0 million, respectively. The Company expects that it will record
increased losses from Excite Japan for at least the remainder of 1998.

YEAR 2000 IMPLICATIONS

    Many currently installed computer systems and software products are coded to
accept only two digit entries in the date code field and cannot distinguish 21st
century dates from 20th century dates. These date code fields will need to
distinguish 21st century dates from 20th century dates and, as a result, many
companies' software and computer systems may need to be upgraded or replaced in
order to comply with such "Year 2000" requirements. The Company has reviewed its
internal programs, and has determined that there are no significant Year 2000
issues within the Company's systems or services. However, although the Company
believes that its systems are Year 2000 compliant, the Company utilizes
third-party equipment and software that may not be Year 2000 compliant. Failure
of such third-party equipment or software to operate properly with regard to the
Year 2000 and thereafter could require the Company to incur unanticipated
expenses to remedy any problems, which could have a material adverse effect on
the Company's business, results of operations and financial condition.
Furthermore, the purchasing patterns of advertisers may be affected by Year 2000
issues as companies expend significant resources to correct their current
systems for Year 2000 compliance. These expenditures may result in reduced funds
available for Web advertising or sponsorship of Web services, which could have a
material adverse effect on the Company's business, results of operations and
financial condition.

LIQUIDITY AND CAPITAL RESOURCES

    At June 30, 1998 the Company had $36.0 million in unrestricted cash, cash
equivalents and short-term investments, an increase of $4.2 million from
December 31, 1997. During the six months ended June 30, 1998, the Company
completed its merger with MatchLogic, Classifieds and Throw. The Company
maintains its cash and cash equivalents in short-term and medium-term
investment-grade interest-bearing securities until required for other purposes.

    The Company's operating activities for the first half of 1998 and 1997 used
cash of approximately $79.9 million and $17.5 million, respectively. The
increased use of cash in 1998 was mainly attributable to the $70.0 million cash
prepayment to Netscape under the Netcenter Agreement. The Company borrowed $50.0
million from Intuit, which is a principal shareholder of the Company, in April
1998 to fund a portion of this payment to Netscape. In June 1998, the Company
repaid the loan in full, plus interest of approximately $410,000, with proceeds
from the Company's public offering which closed in June 1998.

    Investing activities for the first half of 1998 and 1997 used cash of $1.6
million and $17.0 million, respectively. In the first half of 1998 and 1997,
cash was used for purchases of short-term investments, property and equipment,
and contributions towards its investment in Excite Japan, offset by the sales of
short-term investments. Capital expenditures have been, and future expenditures
are anticipated to be, primarily for facilities and equipment to support
expansion of the Company's operations and management information systems. The
Company expects that its capital expenditures will increase as its employee base
grows. As of June 30, 1998, the Company did not have any material commitments
for capital expenditures, although the 



                                       6
<PAGE>   8

Company anticipates that its planned purchases of capital equipment and
leasehold improvements will require additional expenditures during the remainder
of 1998, a portion of which may be financed through equipment leases and bank
borrowings. At June 30, 1998 the Company had $7.7 million available on equipment
lease lines, and the Company believes that additional lease financing will be
available to it if necessary.

    Financing activities for the first half of 1998 and 1997 generated cash of
$86.3 million and $49.2 million, respectively. Financing activities for the
first half of 1998 primarily consisted of cash received in connection with the
issuance of stock through the Company's public offering which was completed in
June 1998 and, to a lesser extent, option exercises under the Company's equity
incentive plan. Financing activities for the first half of 1997 primarily
consisted of a bank line of credit borrowing of $6.0 million and the sale of
Common Stock to Intuit.

    In 1997, the Company entered into and borrowed on a $6.0 million line of
credit. In July 1998, the Company repaid this line in full. The Company is
currently negotiating a new line of credit.

    To date, the Company has had limited international operations and its
exposure to foreign currency exchange rate fluctuations has been minimal. The
Company evaluates its foreign currency exchange rate exposure on an ongoing
basis.

    The Company has completed a number of mergers and acquisitions in the past,
and expects to make other acquisitions and investments in joint ventures in the
future. These mergers resulted in significant increases in headcount and
overhead, as well as the assumption and payment of additional liabilities. While
the Company believes that such transactions have been and will continue to be in
the best interests of the Company and its shareholders, these transactions
involve risks and may require additional cash investments by the Company.

    The Company believes the existing working capital balance together with cash
flows generated from advertising revenues will be sufficient to meet its
anticipated cash needs for working capital, capital expenditures and business
expansion for at least the next twelve months. The Company may need to raise
additional funds sooner in order to fund more rapid expansion, to develop new or
enhanced services or products, to respond to competitive pressures or to acquire
complementary products, businesses or technologies. If additional funds are
raised through the issuance of equity or convertible debt securities, the
percentages ownership of the shareholder of the Company will be reduced,
shareholders may experience additional dilution and such securities may have
rights, preferences or privileges senior to those of the holders of the
Company's common stock.

RISK FACTORS THAT MAY AFFECT FUTURE RESULTS

   Limited Operating History; No Assurance of Profitability. The Company was
founded in June 1994 and generated only limited revenues prior to 1996.
Accordingly, the Company has a limited operating history upon which an
evaluation of the Company and its current business can be based. In addition,
the Company's business model is evolving and relies substantially upon the sale
of Web advertising. The Company's business must be considered in light of the
risks, expenses and problems frequently encountered by companies in their early
stages of development, particularly companies in new and rapidly evolving
markets such as Web advertising. Specifically, such risks include, without
limitation: the inability of the Company to maintain and increase levels of
traffic on the Excite Network; the inability of the Company to derive sufficient
revenues from the Co-Branded Services of Netscape's Netcenter service and the
additional costs the Company expects to incur in order to perform its
obligations under the Netcenter Agreement; the inability of the Company to
effectively integrate the technology and operations of acquired businesses or
technologies with its operations, increased operating expenses as a result of
the Company's recent acquisitions, the inability of the Company to expand its
international operations, particularly in light of the Company's limited
operating experience in the international market; the failure by the Company to
continue to develop and extend the Excite and WebCrawler brands; the inability
of the Company to meet minimum guaranteed impressions under sponsorship
agreements; the inability of the Company to develop or acquire content for its
services; the inability of the Company to generate commerce-related revenues;
the failure of the Company to anticipate and adapt to a developing market; the
introduction and development of equal or superior services or products by
competitors, particularly in light of the fact that Microsoft and Netscape,
operators of two of the most heavily-trafficked Web sites, offer competitive
services; the failure of the market to adopt the Web as an advertising and
commercial medium; reductions in market prices for Web advertising as a result
of competition or otherwise; 



                                       7
<PAGE>   9

the inability of the Company to achieve higher cost per thousand impressions
("CPM") rates for targeted advertising or to increase the percentage of its
advertising inventory sold; government regulation; the inability of the Company
to identify, attract, retain and motivate qualified personnel; and general
economic conditions. There can be no assurance that the Company will be
successful in addressing such risks.

   Potential Fluctuations in Quarterly Results; Unpredictability of Future
Revenues. The Company's operating results have varied on a quarterly basis
during its limited operating history and the Company expects to experience
significant fluctuations in future quarterly operating results. Such
fluctuations have been and may in the future be caused by numerous factors, many
of which are outside the Company's control, including but not limited to:
specific economic conditions relating to the Internet and the Web; usage of the
Web; demand for advertising on the Excite Network as well as demand for
Web-based advertising in general; changes in advertising rates as a result of
competition or otherwise; seasonal trends in advertising sales; the advertising
budgeting cycles of advertisers; incurrence of charges in connection with the
Netcenter Agreement, the Company's distribution relationships and acquisitions;
demand for the Company's services; incurrence of costs relating to acquisitions
of businesses or technologies; introduction or enhancement of new or existing
services by the Company and its competitors; market acceptance of new services;
delays in the introduction of services or enhancements by the Company or its
competitors; mix of types of advertisements sold, such as the amount of targeted
advertising, which generally has higher CPM rates, sold as a percentage of total
advertising sold; capacity constraints and dependencies on computer
infrastructure; and general economic conditions.

   Due to all of the foregoing factors, the Company's quarterly revenues and
operating results are difficult to forecast. The Company believes that
period-to-period comparisons of its results of operations will not necessarily
be meaningful and should not be relied upon as an indication of future
performance. Also, it is likely that in some future quarter or quarters the
Company's operating results will be below the expectations of public market
analysts and investors. In such event, the price of the Company's Common Stock
would be materially and adversely affected. See "Volatility of Stock Price".

    Risks Related to Netcenter Agreement. Under the Netcenter Agreement, the
Company will only receive revenues generated from the Co-Branded Services and
not from any other part of the Netcenter Service. In addition, the Company must
pay Netscape a portion of such revenues after it recoups a majority of the Cash
Payment. Thereafter, the Company must pay Netscape a percentage of the revenues
received from the Co-Branded Services. The amount to be expensed under the
Netcenter Agreement is separated into two components as follows: the amount
which represents the anticipated future net revenues from the Netcenter
Agreement ($29.3 million) will be charged to Distribution License Fees and Data
Acquisition Costs, and the remaining amount ($60.6 million) representing the
combined value of marketing and distribution rights, trademarks and other
exclusivities will be charged ratably over the term of the Agreement to
Amortization of Prepaid Netscape Service. There are no minimum guaranteed
revenues under the Netcenter Agreement, and there can be no assurance as to the
level of revenues that the Company will generate from the Co-Branded Services.
The level of advertising revenues generated by the Company from the Co-Branded
Services is subject to a number of risks and uncertainties, many of which are
beyond the Company's control. These include general risks associated with
providing an advertising-supported Internet service, uncertainty as to whether
the Company can increase its sales and marketing capabilities in order to sell
sufficient advertising on the Co-Branded Services, pricing competition from
Netscape as a result of advertising sold on the parts of Netcenter other than
the Co-Branded Services, and risks that channels on Netcenter other than the
Co-Branded Channels (such as a business channel and a sports channel) may be
potentially more attractive to advertisers than the Co-Branded Services. Because
Netscape is responsible for programming the Netcenter home page and other
portions of Netcenter that are not co-branded, Excite is relying upon Netscape's
programming of the Netcenter home page and other portions of Netcenter to create
a demographic mix of traffic flows that is similar to that experienced by the
Company. Netscape has no experience in such activities. As a result, the Company
has no means of controlling the programming on these pages so as to maximize the
exposure of the co-branded channels and search services. As a result, the
Company also has little means of controlling the mix of traffic to the
co-branded channels and search service, which could have different revenue
opportunities to the Company as advertisers may be willing to pay more to
advertise on certain content channels. As a result, there can be no assurance
that the Company can generate substantial revenues from the Co-Branded Services
to recoup the portion of the Cash Payment against which the Company's revenue
sharing obligations will be offset, or to recoup costs incurred by the Company
under the Netcenter Agreement.



                                       8
<PAGE>   10

    The Company has hired a significant number of technical and sales personnel
and is incurring additional overhead costs in order to develop, host and sell
advertising on the Co-Branded Services. The Company will not be reimbursed for
these costs. The failure to generate revenues from the Co-Branded Services
sufficient to recoup these additional costs would have a material adverse effect
on the Company's business, results of operations and financial condition.

   The success of Netcenter, and the Co-Branded Services in particular, will be
substantially dependent on the amount of traffic on Netcenter. Although Netscape
has made certain exposure guarantees with respect to Netcenter over the term of
the Netcenter Agreement, there can be no assurance that these guarantees will be
fulfilled. There is intense competition for attracting Web users, which
competition may be exacerbated by the upcoming release of Microsoft's Windows 98
operating system. Furthermore, many current Web users may not choose to utilize
Netcenter over other available Internet services. Any failure of Netcenter to
attract substantial user traffic would materially and adversely affect the
Company's business, results of operations and financial condition. Additionally,
the Netcenter Agreement provides that all page views generated from the
Co-Branded Services shall be deemed to be traffic attributable to Netscape. As a
result, the Company may not receive credit, under certain audience measurement
statistics, which are commonly used by advertisers in making their advertising
placements, for traffic generated through the Co-Branded Services.

   As part of the Netcenter Agreement, the Excite Network will also be featured
as a "premier provider" on Netscape's Net Search page, and will be similarly
featured on the "Netcenter Widget" tool, which will be accessible from
Netcenter. Because Netscape only guarantees a specified number of impressions
from its Net Search page (as compared to a number of users who "click through"
to the Excite Network), there can be no assurance that this new "premier
provider" arrangement will result in significant increases in traffic on the
Excite Network. Although Netscape has guaranteed a minimum number of users who
"click through" to the Excite Network from the Netcenter Widget, Netscape is not
obligated to keep this tool on Netcenter after the first six months of the term
of the Netcenter Agreement. Accordingly, there can also be no assurance that
this tool will provide the Excite Network with significant amounts of traffic.
In entering into the Netcenter Agreement, Excite has assumed that "click
throughs" from the Netsearch page will be similar to the historical performance
of the Netsearch page experienced by Excite over the prior two agreements with
Netscape. The "click through" rate is influenced by brand strength of the search
provider, and by the layout and programming of the Netsearch page itself. Thus,
Excite's projections for the co-branded search service are dependent on
Netscape's ability to establish its brand as a search provider and its ability
to program the site to maintain the historical level of "click throughs." Under
performance, in terms of users clicking through from the home page to the
co-branded channels or to Excite services, would negatively impact Excite's
expectations for the Agreement.

   The distribution of traffic from Netscape to Excite throughout the term of
the Netcenter Agreement significantly impacts Excite's ability to recoup the
amount it has prepaid under the Netcenter Agreement. Although Netscape has made
certain traffic exposure guarantees, there can be no assurance that these
guarantees will be fulfilled within the two-year term of this contract. Nor is
there a guarantee that the timing of the delivery of these impressions during
this period will be consistent with the assumptions made in the Company's
determination of the value of the Netcenter Agreement, as Netscape is not
obligated to meet these guarantees on any specific schedule and, if the delivery
of Netscape's traffic guarantees is more heavily weighted toward the end of the
contract term than projected, Excite's expectations as to the net present value
of the Agreement would be negatively impacted.

   Upon the termination of the Netcenter Agreement (other than a termination in
connection with certain acquisitions of or by Netscape), Netscape will have a
perpetual, irrevocable license to utilize certain technology used by Excite to
the Co-Branded Services. Netscape will also have the right to sublicense this
technology to third parties. As a result, upon termination of the Netcenter
Agreement, Netscape will be able to operate Netcenter independently, without any
royalty or payment obligations to Excite. In addition, if Netscape sublicenses
this technology to a third party, the Excite Network could face additional
competition, which could have a material adverse effect on the Company's
business, results of operations and financial condition.

   The Netcenter Agreement is subject to termination if the Company materially
breaches its obligations under the Netcenter Agreement. In addition, if Netscape
believes that the Company's Excite service or that the content provided by
Excite for the Netcenter service contains any content that Netscape deems likely
to cause it material harm, Netscape may terminate the Netcenter Agreement if the
Company has not revised such 



                                       9
<PAGE>   11

objectionable content within five days after notice from Netscape. In the event
of such terminations, Netscape will not be obligated to refund any portion of
the amounts prepaid by the Company and the Company will not be entitled to
receive any reimbursement for its costs incurred in performing its obligations
under the Netcenter Agreement. Moreover, many of the Company's obligations to be
performed under the Netcenter Agreement must be performed according to standards
determined by Netscape at its sole discretion.

   Many of the services to be offered by Netcenter will compete directly with
those offered by the Excite Network. There can be no assurance that this
increased competition for Web users or advertisers will not have a material
adverse effect on the Company's business, results of operations and financial
condition.

   Acquisition Strategy; Integration of Past and Future Acquisitions. The
Company has in the past acquired, and may in the future acquire, businesses,
technologies, services, product lines, content databases, or access to content
databases that are complementary to the Company's business. Acquisitions involve
a number of special risks, including, among other things, the difficulty of
assimilating the technologies, operations and personnel of acquired companies
with those of the Company, the potential disruption of the Company's business,
the diversion of resources, the incurrence of acquisition-related expenses, the
write-off or amortization of intangible assets, the assumption of unknown
liabilities, the inability to maintain uniform standards, controls, procedures
and policies and the impairment of relationships with employees and strategic
partners as a result of such acquisitions or the integration of new personnel.
Any failure to successfully address these acquisition-related risks could have a
material adverse effect on the Company's business, results of operations and
financial condition.

        Risks Related to Sponsorships. The Company derives a substantial portion
of its revenues from sponsorship arrangements with third parties to provide
sponsored services and placements on the Excite Network. In connection with
these arrangements, the Company may receive sponsorship fees, and in connection
with certain of its more recent arrangements it may receive a portion of
transaction revenues received by such sponsors from users originated through the
Excite Network. These arrangements expose the Company to potentially significant
financial risks, including the risk that the Company fails to deliver required
minimum levels of user impressions (in which case, these agreements are
typically subject to termination) and that third party sponsors do not renew the
agreements at the end of their term. These arrangements also require the Company
to integrate sponsors' content with the Company's services, which can require
the dedication of resources and significant programming and design efforts to
accomplish. There can be no assurance that the Company will be able to attract
additional sponsors or that it will be able to renew existing sponsorship
arrangements when they expire. In addition, the Company has granted exclusivity
provisions to certain of its sponsors, and may in the future grant additional
exclusivity provisions. Such exclusivity provisions may have the effect of
preventing the Company, for the duration of such exclusivity arrangements, from
accepting advertising or sponsorship arrangements with respect to portions of a
channel or service, an entire channel, across an entire service or over the
entire Excite Network. The inability of the Company to enter into further
sponsorship or advertising arrangements as a result of its exclusivity
arrangements or otherwise could have a material adverse effect on the Company's
business, results of operations and financial condition.

   Risks Associated with Banner Advertising. The Company derives a substantial
portion of its revenues from the sale of banner advertisements on the Excite
Network. A majority of the Company's customers purchasing banner advertisements
purchase these advertisements on a short-term basis, and many of these customers
may terminate their advertising commitments at any time without penalty.
Consequently, there can be no assurance that these customers will continue or
increase their level of advertising on the Excite Network or that these
customers will not move their advertising to competing Web sites or to other
traditional media. Therefore, there can be no assurance that the Company will be
successful in maintaining or increasing the amount of banner advertising on the
Excite Network, and the failure to do so would have a material adverse effect on
the Company's business, results of operations and financial condition.

   Developing Market; Dependence on Continued Growth in Use of the Web. The
market for the Company's services has recently begun to develop, is rapidly
evolving and is characterized by an increasing number of market entrants who
have introduced or developed services and products for use on the Web or who
seek to derive significant revenues from the sale of advertisements on the Web.
The Company is highly dependent upon the increased use of the Web for
information, publication, distribution and commerce, and there can be no
assurance that the use of the Web for these purposes will continue to grow at
its current rate or at all. The growth of the use of the Web may be inhibited
for a number of reasons, including, but not limited to, 



                                       10
<PAGE>   12

potentially inadequate development of network infrastructure, security concerns,
inconsistent quality of service, lack of availability of cost-effective,
high-speed service and government regulations. To the extent that use of the Web
continues to grow, there can be no assurance that the Internet infrastructure
will continue to support the demands placed on it by such growth or that the
performance or reliability of the Internet will not be adversely affected. In
addition, the Web as an advertising medium has not been available for a
sufficient period of time to gauge its effectiveness as compared with
traditional advertising media, and therefore the Web is an unproven medium for
advertising-supported services. Accordingly, the Company's future operating
results will depend substantially upon the increased use of the Web for
information, publication, distribution and commerce and the emergence of the Web
as an effective advertising medium.

   The Company's ability to generate significant advertising revenues will also
depend on, among other things, the development of a large base of users of the
Company's services possessing demographic characteristics attractive to
advertisers, the ability of the Company to accurately measure its user base and
the ability of the Company to develop or acquire effective advertising delivery
and measurement systems. Many of the Company's advertisers have only limited
experience with the Web as an advertising medium, have not yet devoted a
significant portion of their advertising expenditures to Web-based advertising,
and may not find such advertising to be effective for promoting their products
and services relative to traditional print and broadcast media. The adoption of
Web advertising, particularly by those entities that have historically relied
upon traditional media for advertising, requires the acceptance of a new way of
conducting business and exchanging information. Entities that already have
invested substantial resources in other methods of conducting business may be
reluctant to adopt a new strategy that may limit or compete with their existing
efforts. There can be no assurance that the market for Web advertising will
continue to emerge or become sustainable. If the market fails to develop or
develops more slowly than expected, the Company's business, results of
operations and financial condition could be materially and adversely affected.
No standards have been widely accepted for the measurement of the effectiveness
of Web-based advertising, and there can be no assurance that such standards will
develop sufficiently to support the Web as an effective advertising medium.
There can be no assurance that advertisers will continue to accept the Company's
or other third-party measurements of impressions, or that such measurements will
not contain errors. In such event, the Company's advertising revenues could be
materially adversely affected, which would have a material adverse effect on the
Company's business, results of operations and financial condition.

   In addition, there is intense competition in the sale of advertising on the
Web, resulting in a wide range of rates quoted and a variety of pricing models
offered by different vendors for a variety of advertising services, which makes
it difficult to project future levels of advertising revenues and rates. It is
also difficult to predict which pricing models will be adopted by the industry
or advertisers. For example, advertising rates based on the number of "click
throughs," or user requests for additional information made by clicking on the
advertisement from the Company's network to the advertiser's Web pages, instead
of rates based solely on the number of impressions displayed on users' computer
screens, would materially adversely affect the Company's revenues. As a result
of these risks, there can be no assurance that the Company will be successful in
generating significant future advertising revenues from Web-based advertising,
and the failure to do so would have a material adverse effect on the Company's
business, results of operations and financial condition.

   Further, there can be no assurance that advertisers will determine that
banner advertising, the delivery of which currently comprises a substantial
portion of the Company's revenues, is an effective or attractive advertising
medium, and there can be no assurance that the Company will effectively
transition to any other forms of Web advertising should they develop and achieve
market acceptance. Moreover, "filter" software programs that limit or prevent
advertising from being delivered to a Web user's computer are available.
Widespread adoption of such software by users could have a material adverse
effect upon the commercial viability of Web advertising, which would have a
material adverse effect on the Company's business, results of operations and
financial condition.

2.1. Netcenter Front Page. The Netcenter Front Page will be programmed and
served by Netscape. The Netcenter Front Page will be Netscape branded only and
neither Excite nor any Excite Named Entity will have any branding on the
Netcenter Front Page. Notwithstanding anything to the contrary, (i) AOL branding
that is integral to Netscape's promotion of Netscape AOL Instant Messenger or
(ii) sub-brands of services offered by any Excite Named Entity may appear on the
Netcenter Front Page so long as the primary brand of the Excite Named Entity

Front Page real estate will be used to highlight Co-Branded Channels provided by
Excite consistent with the channels provided by Netscape.

2.2. The Co-Branded Channels. Netscape shall include Netcenter as part of
Netscape's Web Site. The Channels will be allocated between the parties as set
forth in Exhibit G. The Co-Branded Channels will be included within Netcenter.
The Co-Branded Channels shall be offered in the Local Language and targeted

after, yet differentiated from, Excite's Brand Service, in accordance with
Netscape guidelines therefor, and shall be consistent with the overall look,

notice to Excite, revise the guidelines for the Co-Branded Channels and the
means whereby end users may access the Co-Branded Channels, provided that the
accessibility of the Co-Branded Channels within Netcenter is not materially
reduced. Netscape and Excite will cooperate in good faith to establish a
schedule to promptly implement changes to the Co-Branded Channels necessary to
comply with Netscape's revised guidelines. The search box appearing in Netscape
Channels and Co-Branded Channels will offer only the Netscape Branded Search
Service.

                        CONFIDENTIAL TREATMENT REQUESTED


2.3. Co-Branded Channels Pages. Subject to the terms and conditions of this
Agreement, each page of each Co-Branded Channel will: (i) be produced and
managed by Excite, (ii) be served from a "Netscape.com" domain name (or such
other domain name as Netscape may determine), (iii) reside solely on Excite's
servers and (iv) substantially conform to the pro forma Co-Branded Channel page
layout attached hereto as Exhibit H as such Exhibit may be revised by Netscape
from time to time upon reasonable advance notice to Excite. Netscape and Excite
will cooperate in good faith to establish a schedule to promptly implement
changes to the Co-Branded Channels necessary to comply with Netscape's revisions
to the Co-Branded Channel page layout. All access to each page of the Co-Branded
Channels shall be deemed to be via Netscape's Web Site, and therefore shall be
Netscape traffic. Every page of each Co-Branded Channel shall be co-branded by
Netscape and Excite with each party's brand receiving prominence in accordance
with Exhibit H and such co-branding shall appear on a location designated by
Netscape above the fold on each such page in accordance with Exhibit H. The
Service and the Excite Brand Service may be run on the same or separate Excite
servers provided that the servers on which the Service is run shall be equal in
performance and reliability to the server on which the Excite Brand Service is
run throughout the Term. A user interface designated from time to time by
Netscape for the Netscape Branded Search Service shall be included by Excite on
each page within each Co-Branded Channel. Every page within each Co-Branded
Channel shall include a navigational toolbar which shall appear above the fold
and offer end users navigational controls within Netcenter. The overall look and
feel of the toolbar shall be determined by Netscape and be consistent with the
look and feel of the other navigational toolbars within Netcenter. Netscape may
specify that Excite implement other features within each Co-Branded Channel to
ensure consistency across Netcenter Channels and Excite will make reasonable
commercial efforts to provide the capability to facilitate the integration of
these other features into the Co-Branded Channels at the same level of
prominence that similar features are integrated into the Excite Brand Service to
the extent Netscape chooses to incorporate features and functionality as
developed by Excite. Excite will provide capability for Netscape to program
"recirculation" links in the Co-Branded Channels and Directory Service Pages,
Netscape Channels and Search Results Pages to drive traffic back to Netcenter.
Netcenter service links will be the only recirculation links.

2.4. Co-Branded Channels Name. Each page of each Co-Branded Channel shall
include a channel name mutually agreed upon by Netscape and Excite. Excite shall
not independently use such name without Netscape's prior written consent unless
such name is generic or descriptive or such use occurs in connection with
Excite's advertising sales and promotional efforts on behalf of the Co-Branded
Channels. If such name includes a co-branding component that is not generic or
descriptive, Excite may not use such name with Netscape's name expunged unless
such non-generic and non-descriptive component was already in use on the Excite
Brand Service prior to the Effective Date, in which case Excite grants Netscape
a royalty-free perpetual license to use such component in connection with the
Service. The Co-Branded Channels will be co-branded one level down from the
Netcenter Front Page and throughout all the pages linked within the Co-Branded
Channels. The top level branding bar and navigation bar will be provided by
Netscape. Channels programmed by Netscape will not include Excite's branding.
All Netscape Channels will be branded as Netscape shall determine in its sole
discretion.

2.5. Traffic and Reach. All pages generated and delivered within the Co-Branded
Channels, the Netscape Branded Search Service and Directory Service Pages shall
be deemed Netscape traffic. Excite agrees that for the purpose of third party
industry measurement metrics (such as * and * ), the traffic (i.e., page-views)
within the aforementioned areas will be exclusively attributable to Netscape.
Excite and Netscape agree that, for their respective purposes and for the
purpose of third party industry measurement metrics (such as * and * ), the
audience * and * within the aforementioned areas will be * to * parties.
Netscape and Excite will make good faith efforts to obtain the consent of third
party industry measurement firms and will * to * audience * and * to * for *
Pages and * Channel pages.

3. NETSCAPE BRANDED SEARCH SERVICE

3.1. Development.

         3.1.1. Excite shall use its best commercial efforts to develop and
deliver to Netscape the Netscape Branded Search Service (including the technical
specifications therefor) by the Launch Date. The Netscape Branded Search Service
will (i) have the same features and functions as the Internet search and

Directory Service features and functions then-currently available on Excite's
Web Site to the extent Netscape elects to incorporate such features and
functions into the Netscape Branded Search Service, (ii) be available through
search field and directory graphics designed by Netscape, (iii) except as
provided in Section 3.3 with respect to Search Results Pages, be branded as
Netscape shall determine in its sole discretion, and (vi) be consistent with the
overall look, feel and end user experience of Netcenter. The Netscape Branded
Search Service "sampler" which is presented on the Net Search Page will be
co-branded in a manner substantially similar to the mock-up set forth in Exhibit
H.

3.1.2. In addition to, and not in limitation of, any other obligation of Excite
under this Agreement, Excite shall provide Netscape with written notice of any
new Internet search or directory service features or functionality to be
launched by Excite on the Excite Branded Service no less than the earlier of (i)
thirty (30) days prior to the commencement of the testing of such new
functionality by Excite, (ii) thirty (30) days prior to the launch of such new
functionality on the Excite Brand Service (the "Excite Launch"), or (iii) such
other period intended, in good faith, to provide Netscape with sufficient time
to evaluate the new feature or functionality with the goal of a concurrent
launch within Netcenter. Upon receipt of such notice, Netscape shall have ten
(10) business days to notify Excite in writing of Netscape's intention to
incorporate the new Internet search or directory service features or
functionality into the Netscape Branded Search Service and/or Directory Service
or Netscape shall be deemed to have elected to not incorporate the new Internet
search or directory features or functionality in any manner into the Netscape
Branded Search Service and/or Directory Service. If Netscape gives written
notice to Excite stating Netscape's intention to incorporate the new Internet
search or directory service features or functionality into the Netscape Branded
Search Service and/or Directory Service, Netscape and Excite shall make good
faith efforts to mutually agree on a schedule for the incorporation of such new
features or functionality in the Netscape Branded Search Service and/or
Directory Service with the goal of a concurrent launch, and each shall make
reasonable commercial efforts to incorporate the new features or functionality
by the scheduled implementation date. Nothing in this Section will require
Excite to delay the launch of any new Internet search or directory service
features or functionality on the Excite Branded Service.

3.2. Evaluation of the Netscape Branded Search Service. Upon delivery to
Netscape of the Netscape Branded Search Service or any improvement or other
modification thereof pursuant to Section 3.1, Netscape shall evaluate the
Netscape Branded Search Service to determine if the Netscape Branded Search
Service materially conforms to the specifications therefor and Netscape's
graphics design and provides the same features and functions as the search and
Directory Service features and functions available on Excite's Web Site
corresponding to those features and functions selected by Netscape pursuant to
Section 3.1. In the event that Netscape shall discover any error in the Netscape
Branded Search Service that prevents the Netscape Branded Search Service from
materially conforming to the specifications or Netscape's graphics design or, in
the event that the features and functions selected by Netscape pursuant to
Section 3.1 for incorporation into the Netscape Branded Search Services do not
include features and functions equivalent to the corresponding Internet search
and Directory Service features and functions then-currently available on
Excite's Web Site, Netscape will notify Excite of such errors and/or omissions
in writing and Excite shall then use its reasonable commercial efforts to
correct such error and/or omissions and redeliver to Netscape such modified
Netscape Branded Search Service. Upon receipt of such modified Netscape Branded
Search Service, Netscape shall re-evaluate the Netscape Branded Search Service
in accordance with this Section 3.2. In the event of a major malfunction of the
Service or any component thereof within Excite's control, Excite will use its
best efforts to immediately correct such malfunction.

3.3. Search Results Pages. Each Search Results Page will (i) be served to end
users that submit a query or "click" on a directory listing from a Netscape
branded search and/or directory user interface or link, or from a Search Results

other domain name as Netscape may determine), (iv) reside solely on Excite's *

Netcenter. All access to the Search Results Pages shall be deemed via Netscape's
Web Site, and therefore shall be Netscape traffic. The Search Results Pages will
be predominantly Netscape branded (with * of * the * of Netscape's branding) in
accordance with the pro forma layout set forth in Exhibit H, with * placement of
the two brands to be reasonably determined by Netscape. If the term * or * is

4. NET SEARCH PROGRAM

4.1. Participation in the Net Search Program. During the period commencing on
the date that Netscape shall launch the 1998/1999 Net Search Program through the
Term, Excite shall be entitled to participate as a "premier provider" in the Net
Search Program. Such participation shall be subject to Netscape's then-current
applicable Net Search Program guidelines. Excite shall be allocated on the Net
Search Page * percent (*%) of the premier random rotation in a single position
for the Excite Graphic for the duration of the Term. Excite may use its position
within the rotation to feature any one of * search and directory * and * or *
associated with the featured flagship Excite search and directory service, in a
manner substantially similar to the promotional use of Excite's premier provider
"sampler" in the 1997/1998 Net Search program, provided Netscape has been given
reasonable notice prior to any such change. Netscape and Excite will cooperate
in good faith to establish a schedule to implement promptly any such change.
During the 1998/1999 Net Search Program, Netscape agrees not to * a random
rotation percentage * than * . During the 1999 * , excluding Netscape and
Excite, will * than a * within the Net Search Program. On a timeline to be
mutually agreed, the parties will issue a joint press release outlining Excite's
participation in the Net Search Program and outlining the allocation of Excite's
Net Search rotation (where such timing will follow the execution of Netscape's
other Net Search Agreements). Netscape will price, sell, manage and retain all
revenue from the other Premier and Marquee Provider positions on the Net Search
Page. These positions will continue to send traffic to the sites of those
providers.

4.2. Netscape Branded Search Service. During the 1998/1999 Net Search Program,
Netscape shall allocate on the Net Search Page at least * of the premier random
rotation for a link to the Netscape Branded Search Service and, commencing on
the date that Netscape shall launch the 1999/2000 Netscape Program through the
Term, Netscape shall allocate on the Net Search Page at least * of the premier
random rotation for a link to the Netscape Branded Search Service.

4.3. Netcenter Widget. During the period commencing on the date that Netscape
shall launch the 1998/1999 Net Search Program through the Term and provided that
Netscape includes the Netcenter Widget, Netscape shall produce the Netcenter
Widget in a manner that permits end users to submit a query to Excite's Net
Search Program search engine and in a manner that displays the link to Excite's
Net Search Program search engine in a * to that of Excite's * in the Net Search
Program.

5. DIRECTORY SERVICE

5.1. Directory Service. During the Term, Excite will develop, operate and
maintain a Directory Service for Netcenter. The Directory Service for Netcenter
shall be fully functional on the Launch Date and shall be integrated into the
Co-Branded Channels and such other Channels as Netscape shall designate from
time to time. Except as otherwise agreed by the parties, Excite agrees that the
Directory Service for Netcenter shall be equivalent in function, features and
depth, including, without limitation, taxonomy, and shall be updated no less
frequently than the directory service available through the Excite Brand
Service, subject to Netscape's selection of directory features or functionality
pursuant to Section 3.1.

5.2. Taxonomy of Directory Service for Netscape Channels. Excite will provide
the capability for Netscape to deliver a subject based directory service that
would be presented to the user outside the context of a Channel. Excite will
also provide the capability for Netscape to deliver an alphabetically-based
directory service. To the extent that Excite develops a time-based or
location-based directory service for its own purposes, Excite will provide the
capability for Netscape to deliver these directories as well. Excite will
provide "cuts" of the directory to be integrated into the Netscape channels. The
technical teams will work in good faith to assure timely updates to the Netscape
Directory Service. Netscape may, with the assistance of Excite, determine the
taxonomy contained in any Directory Service to be included by Netscape in a
Channel (other than Co-Branded Channels). At Netscape's request from time to
time, upon reasonable advance notice to Excite, Excite shall modify and enhance
the taxonomy of any Directory Service included by Netscape in a Channel (other
than Co-Branded Channels). Netscape and Excite will cooperate in good faith to
establish a schedule to promptly implement changes to the Directory Service
necessary to comply with Netscape's revisions.

5.3. Directory Service Pages. Each Directory Service Page will (i) be served to
end users that "click" on a category or sub-category of the Directory Service
contained on a page within any Channel or on any Search Results Page or
Directory Service Page, (ii) be produced and managed by Excite, (iii) have a
"netscape.com" domain name (or such other domain name as Netscape may
determine), (iv) reside solely on Excite's *, (v) contain links to recirculate
traffic back to Netcenter based on keyword mapping mutually agreed to by the
parties which, in any event, shall recirculate traffic back to Netcenter in a
manner equivalent to the manner which Excite recirculates traffic from its
directory service pages in the Excite Brand Service back to the Excite Brand
Service to the extent that the Directory Service remains substantially similar
to the Excite Brand Service, and (vi) be consistent with the overall look, feel
and end user experience of Netcenter. All access to the Directory Service Pages
shall be deemed via Netscape's Web Site, and therefore shall be Netscape traffic
for all purposes, including, without limitation, third party industry
measurement metrics (such as * and *). Such Directory Service Pages shall be
Netscape branded; provided, that Excite shall be entitled to include above the
fold of each such Directory Services Page an indication that such page is
"powered by" Excite in a manner substantially similar to, and no greater or
smaller in size or prominence as, the attribution to Excite contained on the pro
forma Directory Service Page attached hereto as Exhibit H.

5.4. Directory Service for Netcenter Front Page. In the event that Netscape
shall determine to employ a directory oriented navigation model for the
Netcenter Front Page, Netscape may provide written notice thereof to Excite.
Upon receipt by Excite of any such notice, Excite agrees to use commercially
reasonable efforts to promptly develop for Netscape, in accordance with
specifications and a development schedule to be determined by the parties in
good faith, such directory oriented navigation model for the Netcenter Front
Page.

5.5. Netscape Programming Directory Service. In the event that Netscape decides
to take over responsibility for programming all or part of the Directory
Service, and upon ample prior notice to Excite and an agreed-upon transition
schedule, Excite shall deliver to Netscape all tools, technologies, and other
engineering resources as shall be reasonably necessary to permit Netscape to
manage, produce, operate, modify and support the Directory Service. In such
event, Excite shall also deliver to Netscape regular updates of Excite's
directory service in order for Netscape to maintain the Directory Service in
Netcenter.

6. SERVICE IMPLEMENTATION

 6.1. Core Services; Classifieds.

         6.1.1. Netscape shall include within the Service and Netscape Channels
such Core Services as Netscape shall from time to time determine. Excite agrees
that Excite shall not include, on any page of the Service, any services or
applications that contain features or functions included in any Core Service,
except for the Internet search and Directory features and functions that are
provided by Excite at Netscape's request and, to the greatest extent possible
that does not conflict with either of the parties' existing obligations,
Excite's Classifieds2000 service will be the provider of classifieds
functionality (excluding career and job posting classifieds) throughout the
Netcenter Service. Excite will make reasonable commercial efforts to provide the
capability either for Netscape or for Excite to facilitate the integration of
the Core Services into the Co-Branded Channels, Netscape Channels, Directory
Service Pages and the Netscape Search Results Pages at the same level of
prominence that these services are integrated into the Excite Brand Service to
the extent Netscape chooses to incorporate features and functionality as
developed by Excite pursuant to Section 3.1. Excite will have the right to sell
sponsorships in "bundles" (including channel sponsorships or ads) for the * that
are integrated into the Co-Branded Channels (i.e. * in the * ). These chat and
discussion forums can be co-branded at Excite's request. All other core services
will be Netscape branded or Netscape co-branded with another third party.

         6.1.2. To the greatest extent possible that does not conflict with
either of the parties' existing obligations, Excite's Classifieds2000 service
will be the provider of Classifieds functionality throughout Netcenter (other
than career and/or job areas) and all gross revenue derived from the Classifieds
shall be considered * and will be * to the terms set forth in Exhibit B.

selection of Internet search or directory features or functionality pursuant to
Section 3.1, unless otherwise agreed to by the parties. Excite will adhere to
sub 5-second page delivery to the end user service levels for all pages served
within the Excite delivered portion of the Service. The Service shall not be
disadvantaged or suffer from inferior production, programming, content (unless
Excite is contractually restricted from providing such content to the Service
after having made good faith efforts to eliminate any such restrictions) or
performance relative to the Excite Brand Service. Excite shall in good faith
consider employing in the Service Netscape's technology, if available, rather
than a technology supplied by a Netscape Named Entity which competes with
Netscape products or services, provided that such use of Netscape's technology
does not reduce the performance or production of the Service as compared to
comparable elements of the Excite Brand Service on Excite's Web Site. Excite's
obligation to produce the Service, including production services, technology and
content programming which meet standards established by Excite on Excite's Web
Site and general industry standards, is a material obligation of Excite under
this Agreement. Netscape and Excite agree to work towards a page layout in the
Co-Branded Channels, Search Results Pages and Directory Service Pages which is
consistent with the page layout in Netscape's own Channels and Netcenter.

6.3. [INTENTIONALLY LEFT BLANK]

Internet services may not be promoted through advertising, e-commerce or

long as the primary brand of the competitor does not appear as a component of
the sub-brand, (iii) the Net Search Program, and (iv) other Netscape contractual
obligations

approved Excite's guidelines. If Excite management approval is required for any
category of advertisements, then Netscape shall also approve of such
advertisement before such advertisement is accepted for posting in the Service.
If Excite wishes to change its guidelines for advertising and e-commerce
partners, Excite shall so notify Netscape and the parties shall mutually agree
to any such change as it pertains to the Service Ad Inventory. The parties will
cooperate in good faith to maximize revenue from shopping and E-commerce deals
that involve both parties' Netcenter Channels. Advertising for * is * in the
Search Results Pages and the Co-branded Channels consistent with Excite's
applicable advertising sales policies.

         6.5.2. Advertising and e-commerce services which Excite shall provide
include sales, order processing, serving Service Ad Inventory and E-Commerce
Listings, billing and collection and reporting pursuant to Section 9.2. In
selling Service Ad Inventory and E-Commerce Listings and providing advertising
and e-commerce services hereunder, Excite will carry out such services with
substantially the same diligence and vigor as it employs when selling, managing

Web Site be offered * .

house inventory, Excite's Internet services. Netscape may specify up to * of its
share of the house inventory to promote Netcenter services (including those
co-branded services delivered by Excite). Both parties must mutually approve any
promotion outside these guidelines in advance. Either party may use its
allocation of house inventory as barter to third parties other than Excite Named
Entities or Netscape Named Entities.

basis as if Excite had sold such E-Commerce Listing on the Directory Search Page
in a Co-Branded Channel. 

6.6. Content Provider Participation in the Co-Branded Channels. Excite shall

Content Provider's application and compliance with the guidelines. If any such
Content Provider fails to come into compliance after receipt of notification,
Netscape shall direct Excite to reduce or remove the listing of a non-complying
Content Provider.

6.7. Technical Support by Excite. During the Term, Excite shall provide
technical support services for the Service to Netscape on a timely basis,
appoint a technical contact to whom Netscape may address all technical questions
relating to the Service, and use its commercially reasonable efforts to promptly
remedy any material malfunctioning of the Service. Excite shall perform such
technical support in accordance with the terms set forth in Exhibit D, or as
otherwise provided herein. Excite shall be responsible for subscribers'

use, display, perform, reproduce and distribute such intellectual property

Copyrighted elements contained in a Service and the Net Search Program shall be
the property of the copyright owner.

all intellectual property rights therein, shall be owned by Excite. Subject to

7. END USER REGISTRATION AND CUSTOMER SUPPORT

7.1. User Registration. End users who wish to engage in certain activities in
the Co-Branded Channels may have to register as described in Exhibit A, as such
Exhibit may be revised by Netscape from time to time. Netcenter members will be
able to register for appropriate co-branded content through the personalization
offering. Netscape will develop the end user personalization offering. Until
such time as Netscape's personalization offering is developed, which is
estimated to be 90 days after the Launch Date, Excite may use its
personalization technology to provide personalization functions within the
Co-Branded Channels. Once the Netscape personalization offering is available,
Excite agrees to transition to Netscape's personalization offering in the
Co-Branded Channels after the availability of Netscape's personalization
offering according to a mutually determined schedule and transition plan. To
facilitate this transition, Netscape will give Excite as much advance notice of
the completion and specifications of the personalization offering as reasonably
possible and the parties will cooperate in good faith on hosting, transition and
implementation issues. The co-branded content for which users register on
Netcenter channels maintained by Excite will be integrated with Netscape's
member directory and personalization offering. Excite will support Netscape's
personalization through the deployment of Netscape LDAP/NIB software and use of
the Netscape personalization schema. Excite will support Netscape personalized
summaries through the deployment and provision of RDF+ based summaries of
content provided through

course of dealing with respect to other services it may operate shall be
governed by the terms of Section 8.2.

8.2. Course of Dealing. In consideration of (i) the use of the netscape.com

and resources of those operating systems on a basis equal to that of Microsoft,
Excite shall:

         8.2.1. Within Excite.com, not accord Microsoft's Internet Explorer

19.2. Insurance. Excite, at its sole cost and expense, shall secure and maintain
adequate insurance coverage as is necessary, as a reasonable prudent
businessperson, for Excite to bear all of its obligations under this Agreement.
Excite's insurance shall be primary to any other insurance Netscape may have.
All insurance shall be written by companies with a current A.M. Best rating of
A-, VI or better.

19.3. Dispute Resolution. Any dispute hereunder will be negotiated between the
parties commencing upon written notice from one party to the other. Settlement
discussions and materials will be confidential and inadmissible in any
subsequent proceeding without both parties' consent. If the dispute is not
resolved by negotiation within 45 days following such notice, the parties will
refer the dispute to non-binding mediation conducted by JAMS/EndDispute in Santa
Clara County, California (the "Venue"). The parties will share the costs of
mediation. If the dispute is not resolved after 45 days of mediation, the
parties will refer the dispute to binding arbitration by JAMS/EndDispute in the
Venue. The results of any arbitration will be final and non-appeallable, except
that either party may petition any court of competent jurisdiction in the Venue
to review any decision relating to intellectual property matters (including the
scope of license rights), vacating or modifying erroneous conclusions of law or
findings of fact not supported by substantial evidence. The arbitrator may
fashion any legal or equitable remedy except punitive or exemplary damages,
which both parties waive. The arbitrator will render a written decision, which
may be entered in and enforced by any court of competent jurisdiction, but which
will have no preclusive effect in other matters involving third parties. The
losing party will pay the costs of the arbitration and the reasonable legal fees
and expenses of the prevailing party, as determined by the arbitrator. The
parties will jointly pay arbitration costs pending a final allocation by the
arbitrator. At any point in the dispute resolution process, either party may
seek injunctive relief preserving the status quo pending the outcome of that
process. Except as noted, the parties waive any right to judicial process.
California law, without regard to its conflict-of-law provisions, will govern
this Agreement. The U.S. Arbitration Act and JAMS/EndDispute rules will govern
the arbitration process. Absent fraudulent concealment, neither party may raise
a claim more than 3 years after it arises or any shorter period provided by
applicable statutes of limitations.

19.4. Notices. All notices required or permitted hereunder shall be given in
writing in the English language and shall be addressed to the respective parties
as set forth on the Cover Sheet and shall either be (i) personally delivered, or
(ii) transmitted by internationally-recognized private express courier, and
shall be deemed to have been given on the date of receipt if delivered
personally, or two (2) days after deposit with express courier. Either party may

     Information in confidence and to take all necessary precautions to protect
     such Proprietary Information, (ii) not to divulge any such Proprietary
     Information or any information derived therefrom to any third person, (iii)
     not to make any use whatsoever at any time of such Proprietary Information
     except to evaluate internally whether to enter into the currently
     contemplated business relationship with the Disclosing Party, (iv) not to
     remove or export any such Proprietary Information from the country of the
     Disclosing Party, and (v) not to copy or reverse engineer, reverse compile

     purpose of such internal evaluation and shall cause such employees to
     comply with the obligations set forth herein. The Receiving Party shall
     treat the Proprietary Information with at least the same degree of care and

     public domain and is available at the time of disclosure or which
     thereafter enters the public domain and is available, through no improper
     action of inaction by the Receiving Party or any affiliate, agent or
     employee of the Receiving Party, or (ii) was in the Receiving Party's

     business relationship, or (ii) a request by the Disclosing Party at any
     time, the Receiving Party will turn over to the Disclosing Party all

     the disclosure of any Proprietary Information, which shall be disclosed, if
     at all, solely at the option of the Disclosing Party, or (iii) requires
     either party to proceed with any proposed transaction or relationship in
     connection with which Proprietary Information may be disclosed.

3.   Except to the extent required by law, neither party shall disclose the
     existence or subject matter of the negotiations or business relationship
     contemplated by this Agreement.

4.   The Receiving Party acknowledges and agrees that due to the unique nature
     of the Disclosing Party's Proprietary Information, there may be no adequate
     remedy at law for any breach of its obligations. The Receiving Party
     further acknowledges that any such breach may allow the Receiving Party or
     third parties to unfairly compete with the Disclosing Party resulting in
     irreparable harm to the Disclosing Party and, therefore, that upon any such
     breach or any threat thereof, the Disclosing Party shall be entitled to
     seek appropriate equitable relief in addition to whatever remedies it may
     have at law. The Receiving Party will notify the Disclosing Party in
     writing immediately upon the occurrence of any such unauthorized release or
     other breach.

5.   Neither party acquires any intellectual property rights under this
     Agreement or through any disclosure hereunder, except the limited right to
     use such Proprietary Information in accordance with this Agreement. No
     warranties of any kind are given with respect to the Proprietary
     Information disclosed under this Agreement or any use thereof, except as
     may be otherwise agreed to in writing.

6.   This Agreement supersedes all prior discussions and writings with respect
     to the subject matter hereof, and constitutes the entire agreement between
     the parties with respect to the subject matter hereof. No waiver or
     modification of this Agreement will be binding upon either party unless
     made in writing and signed by a duly authorized representative of each
     party and no failure or delay in enforcing any right will be deemed a
     waiver. In the event that any of the provisions of this Agreement shall be
     held by a court or other tribunal of competent jurisdiction to be
     unenforceable, the remaining portions hereof shall remain in full force and
     effect. This Agreement shall be governed by the laws of the State of
     California without regard to conflicts of laws provisions thereof and each
     party submits to the jurisdiction and venue of any California State or
     federal courts generally serving the Santa Clara county area with respect
     to the subject matter of this Agreement.

                           (b) Based in part on the representations made by the
Investor in Section 4 hereof, the Warrants are being issued, and upon exercise
thereof the Shares will be issued, in compliance with the registration
requirements of the Securities Act of 1933, as amended (the "Securities Act"),
or in compliance with applicable exemptions therefrom, and the registration and
qualification requirements of all applicable securities laws of the states of
the United States.

                  3.5 Governmental Consents. No consent, approval, order or
authorization of, or registration, qualification, designation, declaration or
filing with, any federal, state or local


                                       4
<PAGE>   39

governmental authority on the part of the Company is required in connection with
the consummation of the transactions contemplated hereby and by the Netcenter
Services Agreement, including the issuance of the Warrants and the issuance of
the Shares upon exercise thereof, except for the filing of such qualifications
or filings under the Securities Act and all applicable state securities laws as
may be required in connection with the transactions contemplated by this
Agreement. All such qualifications and filings have been made, in the case of
qualifications, on or prior to the date hereof, and have been made or will be
made, in the case of filings, within the time prescribed by law.

                  3.6 Non-Contravention. The execution, delivery and performance
of this Agreement and the Netcenter Services Agreement by the Company, and the
consummation by the Company of the transactions contemplated hereby and thereby,
including the issuance of the Warrants and the issuance of the Shares upon
exercise thereof, do not and will not (i) contravene or conflict with the
Articles of Incorporation or Bylaws of the Company; (ii) constitute a material
violation of any provision of any federal, state, local or foreign law, rule or
regulation binding upon or applicable to the Company; or (iii) constitute a
default or require any consent under, give rise to any right of termination,
cancellation or acceleration of, or to a loss of any benefit to which the
Company is entitled under, or result in the creation or imposition of any lien,
claim or encumbrance on any assets of the Company under, any contract to which
the Company is a party or any permit, license or similar right relating to the
Company or by which the Company may be bound or affected in such a manner as
would have a Material Adverse Effect on the Company.

                  3.7 Litigation. There is no action, suit, proceeding, claim,
arbitration or investigation ("Action") pending: (a) that seeks to prevent,
enjoin, alter or delay the transactions contemplated by this Agreement and the
Netcenter Services Agreement; or (b) that has not previously been disclosed in
one of the SEC Documents (as defined below) and is currently required to be
disclosed under the rules of the SEC in any registration statement, report or
proxy statement filed with the SEC. The Company is not a party to or subject to
the provisions of any order, writ, injunction, judgment or decree of any court
or government agency or instrumentality having a Material Adverse Effect on the
Company. No Action by the Company is currently pending nor does the Company
intend to initiate any Action that is reasonably likely to have a Material
Adverse Effect on the Company.

                  3.8 Registration Rights. Except as set forth in Section 5
below, the Company is not currently subject to any grant or agreement to grant
to any person or entity any rights (including piggyback registration rights) to
have any securities of the Company registered with the United States Securities
and Exchange Commission (the "SEC" or "Commission") or registered or qualified
with any other governmental authority.

                  3.9      SEC Documents.

                           (a) The Company has furnished to the Investor prior 
to the date hereof copies of its Annual Report on Form 10-K for the fiscal year
ended December 31, 1997 ("Form 10-K"), and all other registration statements,
reports and proxy statements filed by the Company with the Commission on or
after December 31, 1997 (the Form 10-K and such registration 


                                       5
<PAGE>   40

statements, reports and proxy statements are collectively referred to herein as
the "SEC Documents"). Each of the SEC Documents, as of the respective date
thereof, did not, as of the date thereof, contain any untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements made therein, in light of the circumstances under which they were
made, not misleading, except as may have been corrected in a subsequent SEC
Document. The Company is not a party to any material contract, agreement or
other arrangement that was required to have been filed as an exhibit to the SEC
Documents that is not so filed.

                           (b) The Form 10-K contains the Company's audited
financial statements (the "Audited Financial Statements") for the fiscal year
ended December 31, 1997 (the "Balance Sheet Date"). Since the Balance Sheet
Date, the Company has duly filed with the Commission all registration
statements, reports and proxy statements required to be filed by it under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the
Securities Act. The audited and unaudited consolidated financial statements of
the Company included in the SEC Documents filed prior to the date hereof fairly
present, in conformity with generally accepted accounting principles (" GAAP ")
(except as otherwise permitted by Form 10-Q) applied on a consistent basis
(except as may be indicated in the notes thereto), the consolidated financial
position of the Company and its consolidated subsidiaries as at the date thereof
and the consolidated results of their operations and cash flows for the periods
then ended (subject to normal year and audit adjustments in the case of
unaudited interim financial statements).

                           (c) Except as and to the extent reflected or reserved
against in the Company's Audited Financial Statements (including the notes
thereto), the Company has no material liabilities (whether accrued or unaccrued,
liquidated or unliquidated, secured or unsecured, joint or several, due or to
become due, vested or unvested, executory, determined or determinable) other
than: (i) liabilities incurred in the ordinary course of business since the
Balance Sheet Date that are consistent with the Company's past practices, (ii)
liabilities with respect to agreements to which the Investor is a party, and
(iii) other liabilities that either individually or in the aggregate, would not
result in a Material Adverse Effect on the Company.

                           (d) The Company meets the requirements for the use of
Form S-3 for registration of the sale by the Investor of the Registrable
Securities (as defined below), and the Company covenants that it shall file all
reports required to be filed by the Company with the SEC in a timely manner so
as to maintain such eligibility for the use of Form S-3.

                  3.10 Absence of Certain Changes Since Balance Sheet Date.
Since the Balance Sheet Date, the business and operations of the Company have
been conducted in the ordinary course consistent with past practice, and there
has not been:

                           (a) any declaration, setting aside or payment of any 
dividend or other distribution of the assets of the Company with respect to any
shares of capital stock of the Company, or any repurchase, redemption or other
acquisition by the Company or any subsidiary of the Company of any outstanding
shares of the Company's capital stock;

                                       6
<PAGE>   41

                           (b) any damage, destruction or loss, whether or not
covered by insurance, except for such occurrences that have not resulted, and
are not expected to result, in a Material Adverse Effect on the Company;

                           (c) any waiver by the Company of a valuable right or
of a material debt owed to it, except for such waivers that have not resulted,
and are not expected to result, in a Material Adverse Effect on the Company;

                           (d) any material change or amendment to, or any
waiver of any material rights under, a material contract or arrangement by which
the Company or any of its assets or properties is bound or subject, except for
changes, amendments, or waivers that are expressly provided for or disclosed in
this Agreement or that have not resulted, and are not expected to result, in a
Material Adverse Effect on the Company;

                           (e) any change by the Company in its accounting
principles, methods or practices or in the manner it keeps its accounting books
and records, except any such change required by a change in GAAP; and

                           (f) any other event or condition of any character,
except for such events and conditions that have not resulted, and cannot
reasonably be expected to result, in a Material Adverse Effect on the Company.

                  3.11 Full Disclosure. The information contained in this
Agreement, the Disclosure Letter, and the SEC Documents, together with the other
written disclosures made by the Company to the Investor in the course of their
discussions leading to this Agreement, taken together, with respect to the
business, operations, assets, results of operations and financial condition of
the Company is true and complete in all material respects and does not omit to
state any material fact necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading.


         4.  REPRESENTATIONS, WARRANTIES AND CERTAIN AGREEMENTS OF THE INVESTOR.

         The Investor hereby represents and warrants to the Company as follows,
provided, however, that nothing set forth in this Article 4 shall limit or
modify the representations and warranties made by the Company in Article 3.

                  4.1 Authorization. This Agreement has been duly authorized by
all necessary corporate action on the part of the Investor. The Agreement
constitutes the Investor's valid and legally binding obligation, enforceable
against it in accordance with its terms, except as may be limited by (a)
applicable bankruptcy, insolvency, reorganization or other laws of general
application relating to or affecting the enforcement of creditors' rights
generally and (b) the effect of rules of law governing the availability of
equitable remedies. The Investor has full corporate power and authority to enter
into this Agreement.

                                       7
<PAGE>   42

                  4.2 Acquisition for Own Account. The Warrants are being
acquired, and the Shares will be acquired, for the Investor's own account, not
as a nominee or agent, and not with a view to the public resale or distribution
thereof without registration under the Securities Act or an exemption therefrom.

                  4.3      Accredited Investor Status.  The Investor is an 
"accredited investor" within the meaning of Regulation D promulgated under the
Securities Act.

                  4.4 Restricted Securities. The Investor understands that the
Warrants to be issued to the Investor hereunder and the Shares issuable upon
exercise thereof are "restricted securities" under the Securities Act inasmuch
as they are being acquired or will be acquired from the Company in a transaction
not involving a public offering and that under the Securities Act and applicable
regulations thereunder such securities may be resold without registration under
the Securities Act only in certain limited circumstances. The Investor is
familiar with Rule 144 of the SEC, as presently in effect, and understands the
resale limitations imposed thereby and by the Securities Act.

                  4.5 Governmental Consents. No consent, approval, order or
authorization of, or registration, qualification, designation, declaration or
filing with, any federal, state or local governmental authority on the part of
the Investor is required in connection with the consummation of the transactions
contemplated hereby and by the Netcenter Services Agreement, including the
acquisition of the Warrants and the purchase of the Shares upon exercise
thereof. All such qualifications have been made, in the case of qualifications,
on or prior to the date hereof, and have been or will be made, in the case of
filings, within the time prescribed by law.

                  4.6 Non-Contravention. The execution, delivery and performance
of this Agreement and the Netcenter Services Agreement by the Investor, and the
consummation by the Investor of the transactions contemplated hereby and
thereby, including the acquisition of the Warrants and the purchase of the
Shares upon exercise thereof, do not and will not (i) contravene or conflict
with the Certificate of Incorporation or Bylaws of the Investor; (ii) constitute
a material violation of any provision of any federal, state, local or foreign
law, rule or regulation binding upon or applicable to the Investor; or (iii)
constitute a default or require any consent under, give rise to any right of
termination, cancellation or acceleration of, or to a loss of any benefit to
which the Investor is entitled under, or result in the creation or imposition of
any lien, claim or encumbrance on any assets of the Investor under, any contract
to which the Investor is a party or any permit, license or similar right
relating to the Investor or by which the Investor may be bound or affected in
such a manner as would have a Material Adverse Effect on the Investor.

                  4.7 Further Limitations on Disposition. Without in any way
limiting the representations set forth above, the Investor agrees not to make
any disposition of all or any portion of the Warrants without the prior written
consent of the Company, which consent may be withheld in the Company's sole
discretion. The Investor further agrees not to make any disposition of all or
any portion of the Shares unless and until:

                                       8
<PAGE>   43

                           (a) there is then in effect a registration statement
under the Securities Act covering such proposed disposition and such disposition
is made in accordance with such registration statement; or

                           (b) the Investor has notified the Company of the 
proposed disposition and has furnished the Company with a statement of the
circumstances surrounding the proposed disposition, and the Investor has
furnished the Company, at the expense of the Investor or its transferee, with an
opinion of counsel, reasonably satisfactory to the Company, that such
disposition will not require registration of such securities under the
Securities Act.

Notwithstanding the provisions of paragraphs (a) and (b) of this Section 4.7, no
such registration statement or opinion of counsel will be required for any
transfer of any Shares in compliance with SEC Rule 144, Rule 144A or Rule
145(d), or if such transfer otherwise is exempt from the registration
requirements of the Securities Act in the opinion of the Company's counsel.
Furthermore, notwithstanding the other provisions of this Section 4.7, the
Investor shall be permitted to transfer all or any portion of the Warrants (i)
to an underwriter of a public offering of Common Stock if and only if the
Warrants (or any such portion) shall be immediately exercised by such
underwriter and the Shares issued upon such exercise are immediately sold to the
public, (ii) to any affiliate (as that term is defined in the Securities Act) of
the Investor, or (iii) in connection with any merger or consolidation to which
the Investor is a party, any sale of all or substantially all of the Investor's
assets or any other acquisition of the Investor.

                  4.8      Legends.  Certificates evidencing the Warrants and 
the Shares will bear the following legend:

                  THE SECURITIES REPRESENTED HEREBY HAVE 
                  NOT BEEN REGISTERED UNDER THE SECURITIES 
                  ACT OF 1933, AS AMENDED (THE "ACT"), OR
                  UNDER THE SECURITIES LAWS OF CERTAIN 
                  STATES. THESE SECURITIES ARE SUBJECT TO 
                  RESTRICTIONS ON TRANSFERABILITY AND RESALE 
                  AND MAY NOT BE TRANSFERRED OR RESOLD 
                  EXCEPT AS PERMITTED UNDER THE ACT AND THE 
                  APPLICABLE STATE SECURITIES LAWS, PURSUANT 
                  TO REGISTRATION OR EXEMPTION THEREFROM.

The legend set forth above will be removed by the Company from any certificate
evidencing Shares upon delivery to the Company of an opinion by counsel,
reasonably satisfactory to the Company, that a registration statement under the
Securities Act is at that time in effect with respect to the legended security
or that such security can be freely transferred in a public sale without such a
registration statement being in effect and that such transfer will not
jeopardize the exemption or exemptions from registration pursuant to which the
Company issued the Shares.

         5.   NO TREATMENT AS AFFILIATE;  REGISTRATION

                  5.1 No Treatment as Affiliate. On the basis of the facts now
in its possession, upon and following the Closing of the transactions
contemplated by this Agreement, the Company shall not treat the Investor as an
"affiliate" of the Company (as such term is defined in the Securities Act) for
purposes of any federal or state securities laws.

                  5.2      Registration.

                           (a) Certain Definitions.  As used in this Section 
5.2, the following terms shall have the following respective meanings:

                            "Registrable Securities" shall mean (i) all Shares
issued or issuable upon exercise of the Warrants, and (ii) any shares of Common
Stock of the Company issued as (or issuable upon conversion or exercise of any
warrant, right or other security which is issued as) a stock dividend or other
distribution with respect to, or in exchange for or in replacement of, any
Shares; provided, however, that shares of Common Stock or other securities shall
only be treated as Registrable Securities if and so long as they have not been
sold to or through a broker or dealer or underwriter in a public distribution or
a public securities transaction.

                            The terms "register," "registered" and 
"registration" refer to a registration effected by preparing and filing a
registration statement in compliance with the Securities Act, and the
declaration or ordering of the effectiveness of such registration statement.

                            "Registration Statement" shall mean the registration
statement of the Company under the Securities Act contemplated by Section 5.2(b)
below.

                           (b) Registration.

                                    (i)     Mandatory Registration.  The Company
shall prepare and file with the SEC as soon as practicable after the Closing,
but no later than ten (10) days after the Closing Date, a Registration Statement
on Form S-3 (or, if Form S-3 is not then available, on such form of Registration
Statement as is then available to effect a registration of all of the
Registrable Securities) covering the resale of the Registrable Securities. The
Company shall use its best efforts to cause the Registration Statement to become
effective as soon as practicable after filing, but in no event later than the
first to occur of (i) the third (3rd) day after the SEC notifies the Company
that the Registration Statement will not be reviewed by the SEC or that the SEC
does not have any further comments on the Registration Statement and (ii) ninety
(90) days after the Closing Date, and to keep such Registration Statement
current and effective pursuant to SEC Rule 415 at all times until such date as
is the earlier of (A) the date on which all of the Registrable Securities have
been sold, and (B) the date on which all of the Registrable Securities (in the
reasonable opinion of counsel to the Investor) may be immediately sold to the
public without registration or restriction pursuant to Rule 144 under the
Securities Act within a single three-month period (the "Registration Period").
The Registration Statement (and each amendment or supplement thereto, and each
request for acceleration of effectiveness thereof) 


                                       10
<PAGE>   45

shall be provided to, and be subject to the reasonable approval of, the Investor
and its counsel prior to the filing or other submission thereof to the SEC.

                                    (ii)    Permitted Delay Periods; Suspension
of Sales. If at any time prior to the expiration of the Registration Period, the
Chief Executive Officer of the Company has determined in good faith that (A)
compliance by the Company with its disclosure obligations in connection with the
Registration Statement would be seriously detrimental to the Company and its
shareholders, or (B) the Company then is unable to comply with its disclosure
obligations or SEC requirements in connection with the Registration Statement,
then in either such case the Company shall not be required to maintain the
effectiveness thereof or amend or supplement the Registration Statement for a
period (a "Permitted Delay Period") expiring upon the earlier to occur of (I)
the date on which such material information is disclosed to the public or ceases
to be material or the Company is able to so comply with its disclosure
obligations and SEC requirements, or (II) sixty (60) days after the Chief
Executive Officer of the Company makes such good faith determination. The
Company will give prompt written notice to the Investor of each Permitted Delay
Period. Such notice shall state to the extent, if any, as is practicable, an
estimate of the duration of such Permitted Delay Period. The Investor, by its
acceptance of any Registrable Securities, agrees that, upon receipt of such
notice it will forthwith discontinue disposition of the Registrable Securities
pursuant to the Registration Statement, and will not deliver any prospectus
forming a part thereof in connection with any sale of Registrable Securities,
until the expiration of such Permitted Delay Period. There shall not be more
than one (1) Permitted Delay Period in any twelve (12) month period.

                           (c) Obligations of the Company. In connection with
the registration of the Registrable Securities, the Company shall have the 
following obligations:

                                    (i)     No Registration Statement (including
any amendments or supplements thereto and prospectuses contained therein and all
documents incorporated by reference therein) shall contain any untrue statement
of a material fact or omit to state a material fact required to be stated
therein, or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

                                    (ii) The Company shall prepare and file with
the SEC such amendments (including post-effective amendments) and supplements to
the Registration Statement and the prospectus used in connection with the
Registration Statement as may be necessary to keep the Registration Statement
effective at all times during the Registration Period and, during such period,
comply with the provisions of the Securities Act with respect to the disposition
of all Registrable Securities of the Company covered by the Registration
Statement until such time as all of such Registrable Securities have been
disposed of in accordance with the intended methods of disposition by the seller
or sellers thereof as set forth in the Registration Statement.

                                    (iii) The Company shall furnish to the
Investor and its legal counsel (A) promptly after the same is prepared and
publicly distributed, filed with the SEC or received by the Company, one copy of
the Registration Statement and any amendment thereto,


                                       11
<PAGE>   46

each preliminary prospectus and prospectus and each amendment or supplement
thereto, and each letter written by or on behalf of the Company to the SEC or
the staff of the SEC (including, without limitation, any request to accelerate
the effectiveness of the Registration Statement or amendment thereto), and each
item of correspondence from the SEC or the staff of the SEC, in each case
relating to the Registration Statement (other than any portion, if any, thereof
which contains information for which the Company has sought confidential
treatment), (B) on the date of effectiveness of the Registration Statement or
any amendment thereto, a notice stating that the Registration Statement or
amendment has been declared effective, and (C) such number of copies of a
prospectus, including a preliminary prospectus, and all amendments and
supplements thereto and such other documents as the Investor may reasonably
request in order to facilitate the disposition of the Registrable Securities.

                                    (iv) The Company shall (A) register and
qualify the Registrable Securities covered by the Registration Statement under
such securities or "blue sky" laws of such jurisdictions as the Investor
reasonably requests, (B) prepare and file in those jurisdictions such amendments
(including post-effective amendments) and supplements to such registrations and
qualifications as may be necessary to maintain the effectiveness thereof during
the Registration Period, (C) take such other actions as may be necessary to
maintain such registrations and qualifications in effect at all times during the
Registration Period, and (D) take all other actions reasonably necessary or
advisable to qualify the Registrable Securities for sale in such jurisdictions;
provided, however, that the Company shall not be required in connection
therewith or as a condition thereto to (I) qualify to do business in any
jurisdiction where it would not otherwise be required to qualify but for this
Section 5.2(c)(iv), (II) subject itself to general taxation in any such
jurisdiction, (III) file a general consent to service of process in any such
jurisdiction, or (IV) make any change in its charter or bylaws, which in each
case the Board of Directors of the Company determines to be contrary to the best
interests of the Company and its shareholders.

                                    (v)     As promptly as practicable after 
becoming aware of such event, the Company shall notify the Investor of the
happening of any event, as a result of which the prospectus included in the
Registration Statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, and the Company shall
promptly prepare a supplement or amendment to the Registration Statement to
correct such untrue statement or omission and deliver such number of copies of
such supplement or amendment to the Investor as reasonably requested by the
Investor.

                                    (vi) Except as provided in Section
5.2(b)(ii), the Company shall use its best efforts to prevent the issuance of
any stop order or other suspension of effectiveness of the Registration
Statement and, if such an order is issued, to obtain the withdrawal of such
order at the earliest practicable moment (including in each case by amending or
supplementing the Registration Statement). The Company shall promptly notify the
Investor of the issuance of any such order and the resolution thereof (and if
the Registration Statement is supplemented or amended, deliver such number of
copies of such supplement or amendment to the Investor as the Investor may
reasonably request).

                                       12
<PAGE>   47

                                    (vii) The Company shall give a single firm
of counsel designated by the Investor the opportunity to review the Registration
Statement and all amendments and supplements thereto a reasonable period of time
prior to their filing with the SEC, and not file any document in a form to which
such counsel reasonably objects in a timely fashion.

                                    (viii) At the request of the Investor, the
Company shall furnish, on the date of effectiveness of the Registration
Statement, an opinion, dated as of such date, from counsel representing the
Company addressed to the Investor and (1) in the case of an underwritten public
offering, in form, scope and substance as is customarily given in an
underwritten public offering, and (2) in all other cases, as mutually agreed by
the Company and the Investor.

                                    (ix) The Company shall hold in confidence
and not make any disclosure of information concerning the Investor provided to
the Company unless (A) disclosure of such information is necessary to comply
with federal or state securities laws, (B) the disclosure of such information is
necessary to avoid or correct a misstatement or omission in the Registration
Statement, (C) the release of such information is ordered pursuant to a subpoena
or other order from a court or governmental body of competent jurisdiction, (D)
such information has been made generally available to the public other than by
disclosure in violation of this or any other agreement, or (E) the Investor
consents to the form and content of any such disclosure. The Company agrees that
it shall, upon learning that disclosure of such information concerning the
Investor is sought in or by a court or governmental body of competent
jurisdiction or through other means, give prompt notice to the Investor prior to
making such disclosure, and allow the Investor, at its expense, to undertake
appropriate action to prevent disclosure of, or to obtain a protective order
for, such information.

                                    (x)     The Company shall promptly either 
(A) cause all of the Registrable Securities covered by the Registration
Statement to be listed on the NYSE, the AMEX or other national securities
exchange on which securities of the same class or series issued by the Company
are then listed, if any, if the listing of such Registrable Securities is then
permitted under the rules of such exchange, or (B) secure the designation and
quotation of all of the Registrable Securities covered by the Registration
Statement on the Nasdaq National Market and, without limiting the generality of
the foregoing, to arrange for or maintain at least two market makers to register
with the National Association of Securities Dealers ("NASD") as such with
respect to such Registrable Securities.

                                    (xi) The Company shall maintain a transfer
agent and registrar, which may be a single entity, for the Registrable
Securities not later than the effective date of the first Registration
Statement.

                                    (xii) The Company shall cooperate with the
Investor to facilitate the timely preparation and delivery of certificates (not
bearing any restrictive legends) representing Registrable Securities to be
offered pursuant to the Registration Statement and enable such certificates to
be in such denominations or amounts, as the case may be, as the Investor may
reasonably request and registered in such names as the Investor may request,
and, 
                                       13
<PAGE>   48

within five (5) business days after the Registration Statement is ordered
effective by the SEC, the Company shall deliver, and shall cause legal counsel
selected by the Company to deliver, to the transfer agent for the Registrable
Securities (with copies to the Investor) an opinion of such counsel as required
by the transfer agent prior to the transfer of the Registrable Securities.

                                    (xiii) At the request of the Investor, the
Company shall prepare and file with the SEC such amendments (including
post-effective amendments) and supplements to the Registration Statement and the
prospectus used in connection with the Registration Statement as may be
necessary in order to change the plan of distribution set forth in the
Registration Statement.

                                    (xiv) The Company shall comply with all
applicable laws related to the Registration Statement and the offering and sale
of securities thereunder and all applicable rules and regulations of
governmental authorities in connection therewith (including without limitation
the Securities Act and the Securities Exchange Act of 1934, as amended, and the
rules and regulations promulgated by the SEC).

                                    (xv) The Company shall take all such other
actions as the Investor reasonably requests in order to expedite or facilitate
the disposition of such Registrable Securities.

                                    (xvi) From and after the date of this
Agreement, the Company shall not, and shall not agree to, allow the holders of
any securities of the Company to include any of their securities in the
Registration Statement under Section 5.2(b)(i) hereof or any amendment or
supplement thereto under Section 5.2(c)(ii) hereof without the prior written
consent of the Investor. The foregoing shall not apply to the extent, and only
to the extent, that such holders are contractually entitled, as of the date of
this Agreement, to so include their securities in such Registration Statement or
amendment or supplement thereto; provided, however, that the Company shall use
its best efforts to cause such holders to waive their rights to be so included
(it being understood and agreed that the Company will not be required to seek a
waiver from America Online in this regard).

                           (d) Obligations of the Investor. In connection with
the registration of the Registrable Securities, the Investor shall have the
following obligations:

                                    (i)     It shall be a condition precedent to
the obligations of the Company to complete the registration pursuant to this
Agreement with respect to the Registrable Securities that the Investor shall
furnish to the Company such information regarding itself, the Registrable
Securities held by it and the intended method of disposition of the Registrable
Securities as shall be required to effect the registration of such Registrable
Securities and shall execute such documents in connection with such registration
as the Company may reasonably request. At least two (2) business days prior to
the first anticipated filing date of the Registration Statement, the Company
shall notify the Investor of the information the Company requires from the
Investor.

                                       14
<PAGE>   49

                                    (ii) The Investor, by its acceptance of the
Registrable Securities, agrees to cooperate with the Company as reasonably
requested by the Company in connection with the preparation and filing of the
Registration Statement hereunder.

                                    (iii) The Investor agrees that, upon receipt
of any notice from the Company of the happening of any event of the kind
described in Section 5.2(c)(vi) or 5.2(c)(vii), the Investor will immediately
discontinue disposition of Registrable Securities pursuant to the Registration
Statement covering such Registrable Securities until receipt by the Investor of
the copies of the supplemented or amended prospectus contemplated by Section
5.2(c)(vi) or 5.2(c)(vii) and, if so directed by the Company, the Investor shall
deliver to the Company (at the expense of the Company) or destroy (and deliver
to the Company a certificate of destruction) all copies in the Investor's
possession, of the prospectus covering such Registrable Securities current at
the time of receipt of such notice.

                                    (iv) The Investor agrees to comply with the
prospectus delivery requirements under the Securities Act in connection with the
Investor's sales of the Registrable Securities.

                                    (v)     The Investor agrees, for so long as
the Investor owns any Registrable Securities and upon request of the
underwriters managing any underwritten public offering of the Company's Common
Stock, to enter into a standard form of lock-up agreement (not to exceed ninety
(90) days) in connection with such offering, provided that all officers and
directors of the Company and all shareholders of the Company who hold at least
the same number of shares of Common Stock of the Company (including such shares
issuable upon exercise or conversion of exercisable or convertible securities)
as the number of shares of Registrable Securities then held by the Investor,
enter into the same form of lock-up agreement.

                           (e) Expenses of Registration. All reasonable expenses
incurred by the Company or the Investor in connection with registrations,
filings or qualifications pursuant to Sections 5.2(b) and 5.2(c) above,
including, without limitation, all registration, listing and qualifications
fees, printers and accounting fees, the fees and disbursements of counsel for
the Company, the fees and disbursements of one counsel selected by the Investor,
but not underwriting discounts and commissions, shall be borne by the Company.
In addition, the Company shall pay all of the Investor's reasonable costs and
expenses (including legal fees) incurred in connection with the enforcement of
the rights of the Investor hereunder. (f) Indemnification.

                                    (i)     To the extent permitted by law, the
Company will indemnify, hold harmless and defend (A) the Investor, and (B) the
directors, officers, partners, members, employees and agents of the Investor and
each person who controls the Investor within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act, if any, (each, an "Indemnified
Person"), against any joint or several losses, claims, damages, liabilities or
expenses (collectively, together with actions, proceedings or inquiries by any
regulatory or self-regulatory organization, whether commenced or threatened, in
respect thereof, "Claims") to which any of them may become subject insofar as
such Claims arise out of or are based upon: 


                                       15
<PAGE>   50

(A) any untrue statement or alleged untrue statement of a material fact in the
Registration Statement or the omission or alleged omission to state therein a
material fact required to be stated or necessary to make the statements therein
not misleading, (B) any untrue statement or alleged untrue statement of a
material fact contained in any preliminary prospectus if used prior to the
effective date of the Registration Statement, or contained in the final
prospectus related thereto (as amended or supplemented, if the Company files any
amendment thereof or supplement thereto with the SEC) or the omission or alleged
omission to state therein any material fact necessary to make the statements
made therein, in light of the circumstances under which the statements therein
were made, not misleading, or (C) any violation or alleged violation by the
Company of the Securities Act, the Exchange Act, any other law, including,
without limitation, any state securities law, or any rule or regulation
thereunder relating to the offer or sale of the Registrable Securities (the
matters in the foregoing clauses (A) through (C) being, collectively,
"Violations"). Subject to the restrictions set forth in Section 5.2(f)(iii) with
respect to the number of legal counsel, the Company shall reimburse the Investor
and each other Indemnified Person, promptly as such expenses are incurred and
are due and payable, for any reasonable legal fees or other reasonable expenses
incurred by them in connection with investigating or defending any such Claim.
Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section 5.2(f)(i): (A) shall not apply to a Claim
arising out of or based upon a Violation which occurs in reliance upon and in
conformity with information furnished in writing to the Company by such
Indemnified Person expressly for use in the Registration Statement or any such
amendment thereof or supplement thereto; (B) shall not apply to amounts paid in
settlement of any Claim if such settlement is effected without the prior written
consent of the Company, which consent shall not be unreasonably withheld; and
(C) with respect to any preliminary prospectus, shall not inure to the benefit
of any Indemnified Person if the untrue statement or omission of material fact
contained in the preliminary prospectus was corrected on a timely basis in the
prospectus, as then amended or supplemented, if such corrected prospectus was
timely made available by the Company pursuant to Section 5.2(c)(iii) hereof, and
the Indemnified Person was promptly advised in writing not to use the incorrect
prospectus prior to the use giving rise to a Violation and such Indemnified
Person, notwithstanding such advice, used it. Such indemnity shall remain in
full force and effect regardless of any investigation made by or on behalf of
the Indemnified Person.

                                    (ii) The Investor agrees to indemnify, hold
harmless and defend, to the same extent and in the same manner set forth in
Section 5.2(f)(i), the Company, each of its directors, each of its officers who
signs the Registration Statement, its employees, agents and each person, if any,
who controls the Company within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act (collectively and together with an Indemnified
Person, an "Indemnified Party"), against any Claim to which any of them may
become subject, under the Securities Act, the Exchange Act or otherwise, insofar
as such Claim arises out of or is based upon any Violation, in each case to the
extent (and only to the extent) that such Violation occurs in reliance upon and
in conformity with written information furnished to the Company by the Investor
expressly for use in connection with the Registration Statement; and subject to
Section 5.2(f)(iii), the Investor will reimburse any legal or other expenses
(promptly as such expenses are incurred and are due and payable) reasonably
incurred by them in connection with investigating or defending any such Claim;
provided, however, that the 


                                       16
<PAGE>   51

indemnity agreement contained in this Section 5.2(f)(ii) shall not apply to
amounts paid in settlement of any Claim if such settlement is effected without
the prior written consent of the Investor, which consent shall not be
unreasonably withheld; provided, further, however, that the Investor shall be
liable under this Agreement (including this Section 5.2(f)(ii) and Section
5.2(g)) for only that amount as does not exceed the net proceeds actually
received by the Investor as a result of the sale of Registrable Securities
pursuant to the Registration Statement. Such indemnity shall remain in full
force and effect regardless of any investigation made by or on behalf of such
Indemnified Party and shall survive the transfer of the Registrable Securities
by the Investor. Notwithstanding anything to the contrary contained herein, the
indemnification agreement contained in this Section 5.2(f)(ii) shall not inure
to the benefit of any Indemnified Party (i) with respect to any preliminary
prospectus if the untrue statement or omission of material fact contained in the
preliminary prospectus was corrected on a timely basis in the final prospectus,
as then amended or supplemented, and the Indemnified Party failed to utilize
such corrected prospectus, or (ii) with respect to any liability arising from
the failure to deliver any prospectus if the Indemnified Party failed to deliver
such prospectus as required under the Securities Act.

                                    (iii) Promptly after receipt by an
Indemnified Person or Indemnified Party under this Section 5.2(f) of notice of
the commencement of any action (including any governmental action), such
Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is
to made against any indemnifying party under this Section 5.2(f), deliver to the
indemnifying party a written notice of the commencement thereof, and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume control of the defense thereof with counsel
mutually satisfactory to the indemnifying party and the Indemnified Person or
the Indemnified Party, as the case may be; provided, however, that such
indemnifying party shall not be entitled to assume such defense and an
Indemnified Person or Indemnified Party shall have the right to retain its own
counsel with the fees and expenses to be paid by the indemnifying party, if, in
the reasonable opinion of counsel retained by the indemnifying party, the
representation by such counsel of the Indemnified Person or Indemnified Party
and the indemnifying party would be inappropriate due to actual or potential
conflicts of interest between such Indemnified Person or Indemnified Party and
any other party represented by such counsel in such proceeding or the actual or
potential defendants in, or targets of, any such action include both the
Indemnified Person or the Indemnified Party and the indemnifying party and any
such Indemnified Person or Indemnified Party reasonably determines that there
may be legal defenses available to such Indemnified Person or Indemnified Party
which are in conflict with those available to such indemnifying party. The
indemnifying party shall pay for only one separate legal counsel for the
Indemnified Persons or the Indemnified Parties, as applicable, and such legal
counsel shall be selected by the Investor, if the Investor is entitled to
indemnification hereunder, or by the Company, if the Company is entitled to
indemnification hereunder, as applicable. The failure to deliver written notice
to the indemnifying party within a reasonable time after the commencement of any
such action shall not relieve such indemnifying party of any liability to the
Indemnified Person or Indemnified Party under this Section 5.2(f), except to the
extent that the indemnifying party is actually prejudiced in its ability to
defend such action. The indemnification required by this Section 5.2(f) shall be
made by periodic payments of the amount 


                                       17
<PAGE>   52

thereof during the course of the investigation or defense, as such expense,
loss, damage or liability is incurred and is due and payable.

                           (g) Reports Under the Exchange Act.  With a view to
making available to the Investor the benefits of Rule 144 promulgated under the
Securities Act or any other similar rule or regulation of the SEC that may at
any time permit the Investor to sell securities of the Company to the public
without registration ("Rule 144"), the Company agrees to:

                                    (i)     file with the SEC in a timely manner
and make and keep available all reports and other documents required of the
Company under the Securities Act and the Exchange Act so long as the Company
remains subject to such requirements and the filing and availability of such
reports and other documents is required for the applicable provisions of Rule
144; and

                                    (ii) furnish to the Investor, so long as the
Investor owns Registrable Securities, promptly upon written request, (A) a
written statement by the Company that it has complied with the reporting
requirements of Rule 144, the Securities Act and the Exchange Act, (B) a copy of
the most recent annual or other report of the Company and such other reports and
documents so filed by the Company, and (C) such other information as may be
reasonably requested to permit the Investor to sell such securities pursuant to
Rule 144 without registration.

                        WARRANT TO PURCHASE COMMON STOCK


     This Warrant is issued to Netscape Communications Corporation, a Delaware
corporation ("Netscape"), by Excite, Inc., a California corporation (the
"Company"), pursuant to the terms of that certain Warrant Agreement dated as of
April 29, 1998 (the "Agreement"). All provisions of the Agreement applicable
hereto are incorporated herein by reference. Unless otherwise indicated herein,
defined terms shall have the same meaning for the purpose of this Warrant as set
forth in the Agreement.

     1.   Purchase of Shares. Subject to the terms and conditions of the
Agreement and as hereinafter set forth, the holder of this Warrant is entitled,
upon surrender of this Warrant at the principal office of the Company (or at
such other place as the Company shall notify the holder hereof in writing), to
purchase from the Company 423,079 fully paid and nonassessable shares (the
"Shares") of the Common Stock of the Company (the "Common Stock") (which number
of Shares shall be subject to adjustment as provided in Section 7 below).

     2.   Exercise Price. The purchase price for each Share of Common Stock
subject to this Warrant shall initially be $59.0906 per share (which price shall
be subject to adjustment pursuant to Section 7 hereof: such price, as adjusted
from time to time, is herein referred to as the "Exercise Price").

     3.   Exercise Period. This Warrant shall be exercisable immediately and
shall remain exercisable until and including the date which is two (2) years
after the date hereof.

     4.   Method of Exercise.

          (a)  While this Warrant remains outstanding and exercisable in
accordance with Section 3 above, the holder may exercise, in whole or in part,
and from time to tie, the purchase rights evidenced hereby, provided that no
such exercise shall have an aggregate exercise price of less than $2,000,000,
unless the aggregate exercise price of all Shares then remaining subject to this
Warrant shall be less than $2,000,000, in which case this Warrant may only be
exercised in full. Such exercise shall be effected by:

               (i)  the surrender of the Warrant, together with a duly executed
copy of the form of subscription attached hereto, to the Secretary of the
Company at its principal offices; and

               (ii) the payment to the Company in cash of an amount equal to the
aggregate Exercise Price for the number of Shares being purchased.

          (b)  Right to Convert Warrant. The holder hereof shall have the right
to convert this Warrant, by the surrender of this Warrant and the Notice of

such holder appearing on the books of the company), in whole or in part (but not
as to a number of Shares less than eight percent (8%) of the number of Shares
for which this Warrant was initially exercisable, as adjusted pursuant to
Section 7, unless the aggregate number of Shares then remaining subject to this
Warrant was initially exercisable, as adjusted pursuant to Section 7, in which
case this Warrant may only be converted in full), and from time to time, at any
time before the close of business on the last day of the exercise period
provided for in Section 3 hereof, into shares of Common Stock as provided for in
this Section 4(b). Upon exercise of this conversion right, the number of Shares
issuable upon exercise of this Warrant will be reduced by the number of Shares
subject to this Warrant as to which the conversion election is being made, and
the holder hereof shall be entitled to receive that number of shares of Common
Stock of the Company computed as follows:

                    X = Y*(A-B) / A, where:


                    (X)  =    the number of shares of Common Stock
                              issuable upon conversion of this Warrant.

                    (Y)  =    the number of shares of common Stock covered
                              by this Warrant in respect of which the
                              conversion election is being made.

                    (A)  =    the Fair Market Value (as defined below) of
                              one share of Common Stock on the date of
                              conversion of this Warrant.

                    (B)  =    the Exercise Price for one share of Common
                              Stock on the date of conversion of this
                              Warrant.

     If the above calculation results in a negative number, then no share of
Common Stock shall be issued or issuable upon conversion of this Warrant.

     "Fair Market Value" of a share of Common Stock shall mean (i) if the Common
Stock is quoted on the Nasdaq National Market or listed on a national securities
exchange at the date the Notice of Conversion is given, the average closing
price of the Common Stock on the Nasdaq National Market or such national
securities exchange on the ten (10) trading days immediately preceding the date
the Notice of Conversion is given; or (ii) if the Common Stock is not then
quoted on the Nasdaq National market or listed on a national securities
exchange, the price per share which the Company would obtain from a willing
buyer for Common Stock sold by the Company from authorized but unissued shares
as such price shall be agreed upon by the holder hereof and the company or, if
agreement cannot be reached within ten (10) business days of the holder's
election hereunder, as such price shall be determined by a panel of three (3)
appraisers, one (1) to be chosen by the Company, one (1) to be chosen by the
holder and the third to be chosen by the first two (2) appraisers. If the
appraisers cannot reach agreement within thirty (30) days of the holder's
election hereunder, then each appraiser shall deliver its appraisal and the
appraisal which is neither the highest nor the lowest shall constitute the Fair
Market Value. Each party shall bear the cost of the appraiser of the sole
appraiser selected by such party and the cost of the third appraiser shall be
borne one-half by each party. In the event either party fails to choose an
appraiser, the cost of the sole appraiser shall be borne one-half by each party.

     Upon conversion of this Warrant, the holder hereof shall be entitled to
receive a certificate for the number of shares of Common Stock determined as
aforesaid.

evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued as soon as practicable thereafter, and in any event
within five (5) business days of the delivery of the subscription notice.

     6.   Valid Issuance of Shares. The Company covenants that (i) it will at
all times keep reserved for issuance upon exercise hereof such number of shares
of Common Stock as shall be issuable upon such exercise, and (ii) the Shares,
when issued pursuant to the exercise of this Warrant, will be duly and validly
issued, fully paid and nonassessable and free from all taxes, liens, charges and
preemptive or similar rights with respect to the issuance thereof.

     7.   Adjustment of Exercise Price and Number of Shares. The number and kind
of securities purchasable upon exercise of this Warrant and the Exercise Price

          (a)  Adjustment of Exercise Price and Number of Shares. The Exercise
Price and the number and kind of Shares (or other securities) purchasable
hereunder shall be subject to adjustment as follows: In case the Company shall

a distribution on the outstanding shares of Common Stock in shares of Common
Stock of the Company, (ii) subdivide the outstanding shares of Common Stock into
a larger number of shares of Common Stock, (iii) combine the outstanding shares
of Common Stock into a smaller number of shares of Common Stock, then, and in
each such case, the Exercise Price and number of Shares (or other securities)
purchasable hereunder in effect immediately prior to such event shall be
adjusted (and any other appropriate actions shall be taken by the Company) so
that the holder of this Warrant shall be entitled to receive, for the same
aggregate consideration, the number of shares of Common Stock or other
securities of the Company that the holder would have owned or been entitled to
receive upon or by reason of any of the events described above, had this Warrant
been exercised (whether or not otherwise then exercisable.) immediately prior to
the occurrence of such event with respect to any unexercised portion of this
Warrant. Any adjustment made pursuant to this Section 7 shall become effective
retroactively (i) in the case of any such dividend or distribution, to a date
immediately following the close of business on the record date for the
determination of holders of Common Stock entitled to receive such dividend or
distribution or (ii) in the case of any such subdivision, combination or
reclassification, to the close of business on the day upon which such corporate
action becomes effective. In case the Company at any time or from time to time
shall take any action affecting the Common Stock or its other equity interests,
if any, other than an action described above, then an adjustment shall be made
in the Exercise Price and number of Shares (or other securities) purchasable
hereunder in such manner and at such time as the Board of Directors of the
Company in good faith determines to be equitable in the circumstances (such
determination to be evidenced in a resolution, a certified copy of which shall
be mailed to the holder of this Warrant).

          (b)  Corporate Transactions. If at any time after the date hereof and
prior to the expiration hereof. and in case of any capital reorganization or
reclassification, or other change of outstanding Common Stock or other equity
interest, if any, or in the case of any consolidation or merger of the Company
with or into another person (other than a consolidation or merger in which the
Company is the resulting or surviving person and which does not result in any
reclassification or change in the Common Stock or other outstanding equity
interest, if any), or in case of any sale or other disposition to another person
of all or substantially all of the assets of the Company (any of the foregoing,
a

                                       3

<PAGE>   58

"Transaction"), the Company, or such successor or purchasing person. as the case
may be, shall execute and deliver to the holder of this Warrant at least ten
business days prior to effecting any of the foregoing Transactions a certificate
stating that the holder shall have the right thereafter, until the expiration
hereof, in connection with any remaining portion of this Warrant to exercise
this Warrant (for the same aggregate consideration) into the kind and amount
(estimating such amount to the extent necessary) of equity securities or other
securities (of the Company or another issuer) or property or cash which would be
receivable upon such Transaction by a holder of the number of shares of Common
Stock into which such unexercised portion of this Warrant would have been
exercisable for immediately prior to such Transaction (whether or not otherwise
then exercisable).

     8.   No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shah be issued upon the exercise of this Warrant.
but in lieu of such fractional shares the Company shall make a cash payment
therefor on the basis of the Exercise Price then in effect.

     9.   No Stockholder Rights. Prior to exercise of this Warrant. the holder
shall not be entitled to any rights of a stockholder with respect to the Shares.
including (without limitation) the right to vote such Shares. receive dividends
or other distributions thereon. exercise preemptive rights or be notified of
stockholder meetings.

     10.  Transferability. This Warrant may not be transferred or assigned. in
whole or in part. without the prior written consent of the Company, which
consent may be withheld in the Company's sole discretion. provided that the
Investor shall be permitted to transfer all or any portion of this Warrant (1)
to an underwriter of a public offering of Common Stock if and only if the
Warrant (or any such portion) shall be immediately exercised by, such
underwriter and the Shares issued upon such exercise are immediately sold to the
public. (ii) to any affiliate (as that term is defined in the Securities Act) of
the Investor, or (iii) in connection with any merger or consolidation to which
the Investor is a party, any sale of all or substantially all of the Investor's
assets or any other acquisition of the Investor.

     11.  Successors and Assigns. The terms and provisions of this Warrant and
the Agreement shall inure to the benefit of. and be binding upon, the Company
and the holders hereof and their respective successors and permitted assigns.

     12.  Amendments and Waivers. Any waiver or amendment of any term of this

                           FORM OF SUBSEQUENT WARRANT

                                                         Redwood City California
                                                                   April 30,1998

                                  EXCITE, INC.
                        WARRANT TO PURCHASE COMMON STOCK

     This Warrant is issued to Netscape Communications Corporation, a Delaware
corporation ("Netscape"), by Excite, Inc., a California corporation (the
"Company"), pursuant to the terms of that certain Warrant Agreement dated as of
April 29, 1998 (the "Agreement"). All provisions of the Agreement applicable
hereto are incorporated herein by reference. Unless otherwise indicated herein,
defined terms shall have the same meaning for the purpose of this Warrant as set
forth in the Agreement.

     1.   Purchase of Shares. Subject to the terms and conditions of the
Agreement and as hereinafter set forth, the holder of this Warrant is entitled,
upon surrender of this Warrant at the principal office of the Company (or at
such other place as the Company shall notify the holder hereof in writing), to
purchase from the Company that number of fully paid and nonassessable shares
(the "Shares") of the Common Stock of the Company (the "Common Stock"), rounded
to the nearest whole share, as is determined by dividing Twenty-Five Million
Dollars ($25,000,000) by the initial Exercise Price (as defined below)
determined pursuant to Section 2 below (which number of Shares shall be subject
to adjustment as provided in Section 7 below). In the event that Netscape does
not enter into an agreement with a term of at least two (2) years (subject to
earlier termination as provided therein) with MatchLogic, Inc., a wholly-owned
subsidiary of the Company ("MatchLogic"), on or before May 22, 1998, whereby
Netscape (i) utilizes certain of MatchLogic's services in Netscape's Netcenter
or for other purposes, and (ii) is obligated to pay MatchLogic at least
$2,500,000 pursuant to such agreement, then the foregoing amount of $25,000,000
shall be reduced to $10,000,000. The Company agrees that it shall be a condition
to any such reduction that the Company shall have used best efforts, and shall
have caused MatchLogic to use best efforts, to enter into the foregoing
agreement with Netscape on terms reasonably acceptable to the Company.

     2.   Exercise Price. The purchase price for each Share of Common Stock
subject to this Warrant shall initially be equal to the average closing sale
price of one share of Common Stock. as reported on the Nasdaq National Market
for the thirty (30) most recent trading days ending on the third trading day
preceding April 30, 1999 (which price shall be subject to adjustment pursuant to
Section 7 hereof-, such price, as adjusted from time to time, is herein referred
to as the "Exercise Price'"). Notwithstanding the foregoing, in the event that a
Corporate Transaction (as defined below) occurs prior to April 30, 1999, then
the Exercise Price shall initially be equal to (subject to adjustment pursuant
to Section 7 below) the average closing sale price of one share of Common Stock,
as reported on the Nasdaq National Market for the thirty (30) most recent
trading clays ending on the thirtieth (30th) trading day preceding the first
public announcement of such Corporate Transaction. In the event that closing
sales prices of the Common Stock cease to be reported on the Nasdaq National
Market, then the foregoing references to the Nasdaq National Market shall be
deemed references to the primary national securities exchange or stock quotation
system on which the Common Stock is then traded or included.

     3.   Exercise Period. This Warrant shall become exercisable on April 30,
1999 and shall thereafter be exercisable until and including the date which is
two (2) years after the date hereof.

<PAGE>   62

Notwithstanding the foregoing, in the event that a Corporate Transaction (other
than a Corporate Transaction in which Netscape is the acquiror) occurs prior to
April 30, 1999, then this Warrant shall become exercisable on the date of the
first public announcement of such Corporate Transaction and shall thereafter be
exercisable until and including the date which is two (2) years after the date
hereof A "Corporate Transaction" shall mean any of the following transactions:

          (a)  a merger or consolidation in which the Company is not the
surviving entity, and where the shareholders of the Company immediately prior to
such merger or consolidation do not own, immediately after such merger or
consolidation, by virtue of securities of the surviving entity issued in respect
of their shares of Common Stock (or other securities) of the Company, Common
Stock (or other securities) of the surviving entity representing more than fifty
percent (50%) of the combined voting power of the outstanding securities of the
surviving entity;

          (b)  the sale, transfer or other disposition of all or substantially
all of the assets of the Company, where the shareholders of the Company
immediately prior to such sale, transfer or other disposition do not own,
immediately after such sale, transfer or other disposition, by virtue of
securities of the purchasing entity issued in respect of their shares of Common
Stock (or other securities) of the Company, Common Stock (or other securities)
of the purchasing entity representing more than fifty percent (50%) of the
combined voting power of the outstanding securities of the purchasing entity; or

          (c)  any reverse merger in which the Company is the surviving entity
but in which the shareholders of the Company immediately prior to such merger do
not continue to own, immediately after such merger, by virtue of their shares of
Common Stock (or other securities) of the Company owned immediately prior to
such merger, Common Stock (or other securities) of the Company representing more
than fifty percent (50%) of the combined voting power of the outstanding
securities of the Company.

     4.   Method of Exercise.

          (a)  While this Warrant remains outstanding and exercisable in
accordance with Section 3 above, the holder may exercise, in whole or in part,
and from time to time, the purchase rights evidenced hereby, provided that no
such exercise shall have an aggregate exercise price of less than $2,000,000,
unless the aggregate exercise price of all Shares then remaining subject to this
Warrant shall be less than $2,000,000, in which case this Warrant may only be
exercised in full. Such exercise shall be effected by:

               (i)  the surrender of the Warrant, together with a duly executed
copy of the form of subscription attached hereto, to the Secretary of the
Company at its principal offices; and

               (ii) the payment to the Company in cash of an amount equal to the
aggregate Exercise Price for the number of Shares being purchased.

          (b)  Right to Convert Warrant. The holder hereof shall have the right
to convert this Warrant, by the surrender of this Warrant and the Notice of
Conversion form annexed hereto duly executed at the office of the Company in
Redwood City, California (or such other office or agency of the Company as it
may designate by notice in writing to the registered holder hereof at the
address of such holder appearing on the books of the Company), in whole or in
part (but not as to a number of Shares less than eight percent (8%) of the
number of Shares for which this Warrant was initially exercisable, as adjusted
pursuant to Section 7, unless the aggregate number of Shares then remaining
subject to this Warrant shall be less than eight percent (8%) of the number of
Shares for which this Warrant was

                                       8

<PAGE>   63


initially exercisable, as adjusted pursuant to Section 7, in which case this
Warrant may only be converted in full), and from time to time, at any time
before the close of business on the last day of the exercise period provided for
in Section 3 hereof, into shares of Common Stock as provided for in this Section
4(b). Upon exercise of this conversion right, the number of Shares issuable upon
exercise of this Warrant will be reduced by the number of Shares subject to this
Warrant as to which the conversion election is being made, and the holder hereof
shall be entitled to receive that number of shares of Common Stock of the
Company computed as follows:

                         X    =    Y*(A-B) / A, where:

                        (X)   =    the number of shares of Common Stock
                                   issuable upon conversion of this Warrant.

                        (Y)   =    the number of shares of Common Stock covered
                                   by this Warrant in respect of which the
                                   conversion election is being made.

                        (A)   =    the Fair Market Value (as defined below) of
                                   one share of Common Stock on the date of
                                   conversion of this Warrant.

                        (B)   =    the Exercise Price for one share of
                                   Common Stock on the date of conversion
                                   of this Warrant.

     If the above calculation results in a negative number, then no shares of
Common Stock shall be issued or issuable upon conversion of this Warrant.

     "Fair Market Value" of a share of Common Stock shall mean (i) if the Common
Stock is quoted on the Nasdaq National Market or listed on a national securities
exchange at the date the Notice of Conversion is given, the average closing
price of the Common Stock on the Nasdaq National Market or such national
securities exchange on the ten (10) trading days immediately preceding the date
the Notice of Conversion is given; or (ii) if the Common Stock is not then
quoted on the Nasdaq National Market or listed on a national securities
exchange, the price per share which the Company would obtain from a willing
buyer for Common Stock sold by the Company from authorized but Unicode shares as
such price shall be agreed upon by the holder hereof and the Company or, if
agreement cannot be reached within ten (10) business days of the holder's
election hereunder, as such price shall be determined by a panel of three (3)
appraisers, one (1) to be chosen by the Company, one (1) to be chosen by the
holder and the third to be chosen by the first two (2) appraisers. If the
appraisers cannot reach agreement within thirty (30) days of the holder's
election hereunder, then each appraiser shall deliver its appraisal and the
appraisal which is neither the highest nor the lowest shall constitute the Fair
Market Value. In the event either party fails to choose an appraiser within
thirty (30) days of the holder's election hereunder, then the appraisal of the
sole appraiser shall constitute the Fair Market Value. Each party shall bear the
cost of the appraiser selected by such party and the cost of the third appraiser
shall be borne one-half by each party. In the event either party fails to choose
an appraiser, the cost of the sole appraiser shall be borne one-half by each
party.

     Upon conversion of this Warrant, the holder hereof shall be entitled to
receive a certificate for the number of shares of Common Stock determined as
aforesaid.

          (c)  Expenses. The Company shall pay all expenses, taxes (other than
transfer taxes) and other charges payable in connection with the preparation,
issuance and delivery of this Warrant and the Shares.

     5.   Certificates for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued as soon as practicable thereafter, and in any event
within five (5) business days of the delivery of the subscription notice.

     6.   Valid Issuance of Shares. The Company covenants that (i) it will at
all times keep reserved for issuance upon exercise hereof such number of shares
of Common Stock as shall be issuable upon such exercise, and (ii) the Shares,
when issued pursuant to the exercise of this Warrant, will be duly and validly
issued, fully paid and nonassessable and free from all taxes, liens, charges and
preemptive or similar rights with respect to the issuance thereof

     7.   Adjustment of Exercise Price and Number of Shares. The number and kind
of securities purchasable upon exercise of this Warrant and the Exercise Price
shall be subject to adjustment from time to time as follows:

          (a)  Adjustment of Exercise Price and Number of Shares. The Exercise
Price and the number and kind of Shares (or other securities) purchasable
hereunder shall be subject to adjustment as follows: In case the Company shall
at any time prior to the expiration of this Warrant, (i) pay a dividend or make
a distribution on the outstanding shares of Common Stock in shares of Common
Stock of the Company, (ii) subdivide the outstanding shares of Common Stock into
a larger number of shares of Common Stock, (iii) combine the outstanding shares
of Common Stock into a smaller number of shares of Common Stock, or (iv) issue
any equity interest in a reclassification of the Common Stock, then, and in each
such case, the Exercise Price and number of Shares (or other securities)
purchasable hereunder in effect immediately prior to such event shall be
adjusted (and any other appropriate actions shall be taken by the Company) so
that the holder of this Warrant shall be entitled to receive, for the same
aggregate consideration, the number of shares of Common Stock or other
securities of the Company that the holder would have owned or been entitled to
receive upon or by reason of any of the events described above, had this Warrant
been exercised (whether or not otherwise then exercisable) immediately prior to
the occurrence of such event with respect to any unexercised portion of this
Warrant. Any adjustment made pursuant to this Section 7 shall become effective
retroactively (i) in the case of any such dividend or distribution, to a date
immediately following the close of business on the record date for the
determination of holders of Common Stock entitled to receive such dividend or
distribution or (ii) in the case of any such subdivision, combination or
reclassification, to the close of business on the day upon which such corporate
action becomes effective. In case the Company at any time or from time to time
shall take any action affecting the Common Stock or its other equity interests,
if any, other than an action described above, then an adjustment shall be made
in the Exercise Price and number of Shares (or other securities) purchasable
hereunder in such manner and at such time as the Board of Directors of the

                                  NO: 004327-1


This Addendum No. 1 (the "Addendum") is entered into by and between NETSCAPE
COMMUNICATIONS CORPORATION, a Delaware corporation, with principal offices at
501 E. Middlefield Road, Mountain View, California 94043 ("Netscape"), and
EXCITE, INC., a California corporation, with principal offices at 555 Broadway,
Redwood City, CA 94063 ("Excite") and effective as of the date of execution by
Netscape ("ADDENDUM EFFECTIVE DATE").

WHEREAS, the parties have entered into a Netcenter Services Agreement effective
April 29, 1998 (the "Agreement"); and

WHEREAS, the parties wish to supplement the provisions of such Agreement with
the Netscape U.S. English Language Net Search Premier Provider Program
guidelines;

NOW, THEREFORE, the parties, in consideration of the terms and conditions
herein, agree as follows:

OBJECTIVE: To direct users of a Netscape client software Internet browser
product ("BROWSER") to U.S. English-language Internet search and directory
services.

1.   PREMIER PROVIDER. Excite will be a premier provider of search and directory
service for the U.S. English-language HTML page ("PREMIER PROVIDER") accessible
by the public via the Internet at the Universal Resource Locator ("URL")
http://home.netscape.com/home/internet-search or such other URL as Netscape may
designate from time to time in writing ("PAGE"). The Page is part of the
collection of U.S. English-language HTML documents accessible by the public via
the Internet at the URL http://home.netscape.com and/or at such other URL(s) as
Netscape may designate ("NETSCAPE'S WEB SITE"). The Page may also be accessed by
Internet users of the Netscape-distributed English-language version of the
Browser by pressing or "clicking" on the Net Search button, or such other
methods as Netscape may specify from time to time. Notwithstanding the
foregoing, Netscape reserves the right to determine other means whereby users
may access the Page, which provides Internet search and directory services on
Netscape's Web Site, including, but not limited to, the use of mirror sites and
pointers based on a user's IP address, and which mirror sites and pointers are
separate and distinct from the Page described in this Agreement.*

2.   PREMIER PERIOD. Netscape will maintain the Premier Graphic, as defined
below, on the Page for the following two-year period ("PREMIER PERIOD"):

* Confidential Treatment has been requested with respect to certain portions of
this exhibit. Confidential portions have been omitted from the public filing and
filed separately with the Securities and Exchange Commission.

3.   SERVICES PROVIDED BY NETSCAPE.

     3.1. Premier Graphic. Each of the participants, including Premier Provider,
in this Net Search Program (the "PREMIER PROVIDER(S)") will supply Netscape with
HTML and/or GIF files, or files of such other format as may be designated from
time to time in writing by Netscape, which conform to the specifications in
Exhibit 1 (such files comprise, for Premier Provider, the "PREMIER GRAPHIC" and
for the Premier Providers, the "PREMIER GRAPHICS"), which Netscape will place on
the Page during the Premier Period. Premier Provider shall retain all right,
title and interest in and to the Premier Graphic (including the copyright
ownership thereof), and Premier Provider hereby grants Netscape a royalty-free
worldwide license, without payment or other charge therefor, to use, display,
perform, reproduce and distribute the Premier Graphic, and such other licenses
with respect to the Premier Graphic necessary to fulfill the intention of this
Agreement. The Premier Graphic shall contain a functional search field and, if
available, directory tree. The specifications of the Premier Graphic and the
placement on the Page of the Premier Graphics are set forth on Exhibit 1 hereto.
Premier Provider's compliance with the content as well as the language,
technical, visual and functional specifications set forth in Exhibit 1 are a
material obligation of Premier Provider under this Agreement. Netscape may, upon
notice to Premier Provider, revise Exhibit 1, provided that the display of the
Premier Graphics shall remain the largest and most prominent category of search
graphics on the Page, shall remain equivalent in size for each of the Premier
Providers, shall not differ substantially, including, without limitation, any
reduction in the size of the Premier Graphic, from the current specifications
for the Premier Graphics set forth in Exhibit 1 hereto and, pursuant to Section
11.7 of the Agreement, shall not change the form or function of the Page in a
manner that materially adversely affects the performance of the program as
compared to its performance at the time the Agreement was executed.

     3.2. Stack. Netscape will produce the Page as set forth on Exhibit 1. The
Premier Graphics on any Page will appear to be overlapped in a stack (the
"STACK"). A Premier Graphic will be accessible by the end user by pressing or
"clicking" on a tab for the relevant Premier Provider's service. Netscape will
produce the Page such that when an end user presses or "clicks" on hypertext
links ("PREMIER LINKS") placed by Premier Provider on the Premier Graphic, the
end user's Browser will access Premier Provider's applicable HTML pages located
at the applicable URL's ("PREMIER URL'S") for such pages on the collection of
English- language HTML documents Premier Provider maintains as its primary web
site whose home page is located at the URL http://www.excite.com or such other
web site of any of Premier Provider's flagship search and directory services and
any online services or channels associated with the featured flagship search and
directory service, pursuant to Section 4.1 of the Agreement ("PREMIER PROVIDER'S
WEB SITE").

     3.3. Rotation. Netscape will rotate the display of the Premier Graphics to
be displayed on the top of the Stack when each Page is served to an end user who
has not selected a Premier Graphic as a default, as described in Section 3.4 of
this Addendum. Subject to the provisions of Section 4.1 of the Agreement and
Section 3.4 of this Addendum, the Premier Graphic will appear on the top of the
Stack of each Page * ( * %) ("ROTATION PERCENTAGE") of the time in which the
Page is served up to end users who have not selected a particular Premier
Graphic or selected a default Premier Graphic when accessing the particular
Page. Premier Provider acknowledges that the Rotation Percentage is an
annualized target, and that, accordingly, at any given time the display of the
Premier Graphic may be adjusted by Netscape to occur above or below the Rotation
Percentage, subject at all times to the impression guarantee and Premier Graphic
rotation adjustment mechanism described in Section 11.2 of the Agreement and,
pursuant to Section 11.7 of the Agreement, Netscape's obligation to not change
the form or function of the Page in a manner that materially adversely affects
the performance of the program as compared to its performance at the time the
Agreement was executed.

<PAGE>   3

     3.4. End User Default. Netscape shall produce each Page such that the end
user may select which Premier Graphic, including, without limitation, the
Premier Graphic, the end user would prefer to have displayed on the top of the
Stack upon the calling up of each Page by such end user. If an end user selects
a favorite, default Premier Graphic, the Premier Graphic selected by the end
user will be displayed on top of the Stack when that end user accesses such
Page. If an end user has elected to have a particular Premier Graphic appear on
top of the Stack on a default basis, the other Premier Graphics, including,
without limitation, the Premier Graphic, to the extent the Premier Graphic is
not selected as such default, will not appear on the top of the Stack unless
selected by the end user.

     3.5. Page Specifications. The specifications of each of the Premier
Graphics, including, without limitation, the Premier Graphic, the Stacks, and
their placement on the Page are set forth on Exhibit 1 hereto; provided however,
that Netscape may, subject to Section 11.7 of the Agreement and upon notice to
Premier Provider, (i) change the location of the Stacks or the Premier Graphics
on the Page, (ii) redesign or reconfigure the Stacks, the Page, Netscape's Web
Site, and/or the manner in which an end user interacts with any of the pages of
Netscape's Web Site, or (iii) revise Exhibit 1, and Premier Provider shall
promptly, and in any event, within no more than thirty (30) days following
receipt of the notice, supply Netscape with a revised Premier Provider Premier
Graphic which conforms to the specifications of the revised Exhibit 1. Netscape
reserves the right to use, in its sole discretion, those portions of the Page
not used by the Stack. In the event that Netscape revises Exhibit 1 and Premier
Provider must supply conforming materials, such conforming materials shall be
received by Netscape and fully functional no later than five (5) days (excluding
holidays) prior to the date Netscape specifies for the posting of the revised
Premier Provider Premier Graphic or Stack on Netscape's Web Site. If Netscape
has not received such revised and conforming materials no later than five (5)
days prior to the date Netscape specifies for the posting of the revised Premier
Provider Premier Graphic or Stack on Netscape's Web Site, or if the materials
supplied by Premier Provider do not function in accordance with the
specifications set by Netscape, then Netscape shall either (i) post previous
versions of Premier Provider's supplied materials, or (ii) make such changes as
necessary to bring the materials into conformity with the new specifications,
until such time as the specifications of Exhibit 1 are again revised.

     3.6. Update of Premier Graphic. Premier Provider may elect to revise or
update its Premier Graphic, provided that such Premier Graphic complies with the
specifications of Exhibit 1. Netscape shall provide Premier Provider with a
"Program Schedule" of material due dates and planned updates attached hereto as
Exhibit 2.

4.   ADDITIONAL PREMIER PROVIDER BENEFITS.

     4.1. Limit on Premier Providers. Netscape shall limit the number of
companies whose tabs appear on the Stack at any one time to a total of seven (7)
entities. Netscape shall allocate the rotation of Premier Graphics in
conformance with Sections 4.1 and 4.2 of the Agreement.

5.   DEFINITION OF IMPRESSION AND CLICK

     5.1. (a) Impression Defined. An impression for the purposes of the
Agreement and the Addendum ("Impression") occurs upon the serving up to an end
user of: (i) the HTML pages displaying the Premier Graphic on the top of a Stack
as described in Section 5.1 (b) below; (ii) any of Premier Provider's Web Site
in conjunction with a search query executed by an end user through entering the
search terms in the URL window of a Browser; (iii) a link through a Disabling
Device only if and to the extent permitted under Section 6.2; or (iv) any other
Premier Provider content as a consequence of an end user accessing a promotional
page on Netscape's Web Site if the parties agree that such promotional page
traffic shall constitute an Impression.

          (b)  Premier Provider's Premier Graphics may be served on the top of
the Stack to an end user by the following means: (i) the Premier Graphics is
displayed as part of a random rotation, as described in Section 3.3 of this
Addendum; (ii) the Premier Graphic has been set as an end user's default


                                       3
<PAGE>   4

selection, as described in Section 3.4 of this Addendum; or (iii) an end user
selects or clicks on the Premier Graphic tab in the Stack.

     5.2  Click Defined. A click ("Click") for the purposes of the Agreement and
the Addendum means an action typically resulting from a user positioning his
mouse cursor on the clickable hyperlink on the Netcenter Front Page linking the
Netcenter Widget to Premier Provider's search engine and selecting or clicking
on that hyperlink. Clicks are counted as a redirection of a user's click through
the Netscape server access logs to any page on the Premier Provider's Web Site.

6.   PREMIER PROVIDER OBLIGATIONS. In addition to the other obligations set
forth herein, Premier Provider agrees to the following provisions.

     6.1. Mailto Link. Premier Provider shall include on the page served to an
end user in conjunction with the results of the end user's search query on
Premier Provider's service a "mailto" link which users of Premier Provider's
service can use to direct questions or help requests to Premier Provider.
Netscape shall also include such a "mailto" link on the page. Premier Provider
will use reasonable efforts to reply promptly, but in any event within one (1)
week, to any such question or help request.

     6.2. No Disabling. Premier Provider shall not provide or implement any
means or functionality that would (i) alter, modify or enable end users to alter
or modify, the Browser standard user interface or configuration, (ii) disable
any functionality of the Browser or any other Internet browser software, or
(iii) modify the functioning of pages served from Netscape's Web Site
("Disabling Devices"). If Premier Provider changes its policy regarding no
Disabling Devices, Premier Provider shall provide Netscape with prompt written
notice thereof and shall establish and maintain controls and procedures
sufficient to timely and accurately determine the number of Impressions
resulting from Disabling Devices and report to Netscape the number of refers to
the Premier Provider Web Site resulting from Disabling Devices. In the event
that the number of Impressions resulting from Disabling Devices in any one (1)
month period exceeds one percent (1%) of the aggregate number of times that the
Page is served up to end users during such month, Netscape shall be relieved of
its obligations under Section 11.8 of the Agreement.

     6.3. Use of Premier Graphic Space. Premier Provider shall: (i) not use, or
assign the right to use, the space allotted the Premier Graphic, or links

described in Section 8 of the Agreement.

7.   PAYMENT TO NETSCAPE.

     7.1. Payment Terms. Except as otherwise set forth herein or in the

the other, via email to the email address set forth below, with usage reports
("USAGE REPORTS") containing the information and in the format set forth in

<PAGE>   5

deliver the Usage Reports within fifteen (15) days following the end of each

of a Usage Report in any given month, the following data shall be used for each
day for which data is missing: ninety percent (90%) of the usage figures
reported for the same day of the week most recently reported (e.g. if data for
the day seven (7) days prior is available, ninety percent (90%) of the usage
figures for such day; if not available, the data for the day fourteen (14) days
prior, and so on).

     8.2. No Liability. NETSCAPE AND PREMIER PROVIDER WILL USE REASONABLE
COMMERCIAL EFFORTS TO ENSURE THE TIMELY DELIVERY, ACCURACY AND COMPLETENESS OF

LIABLE FOR ANY CLAIMS AS THEY RELATE TO SUCH USAGE REPORTS.

9.   TERMINATION.

     9.1  Effect of Termination. Except as specifically provided otherwise in
this Agreement, upon the expiration or termination of the Agreement, all rights
and obligations hereunder shall cease (other than Premier Provider's payment
obligations hereunder to the extent accrued on or prior to the termination date
or as otherwise provided in this Section 9.1) and each party will promptly and
at the direction of the other party, either return or destroy, and will not take
or use, any items of any nature that belong to the other party and all items

that any credit provided by Premier Provider to Netscape pursuant to Section 4
of Exhibit B of the Agreement shall not be applied against advertising services
provided by Premier Provider to Netscape during the Premier Period, such section
shall survive the expiration or termination of this Agreement until all such
credits shall be applied against such services.

     9.2. No Compensation. Premier Provider shall not be entitled to any
compensation, damages or payments in respect to goodwill that has been
established or for any damages on account of prospective profits or anticipated
sales, and Premier Provider shall not be entitled to reimbursement in any amount
for any training, advertising, market development, investments, leases or other
costs that shall have been expended by either party before the expiration or
termination of this Agreement, regardless of the reason for or method of
termination of this Agreement. Premier Provider hereby waives its rights under
applicable laws for any such compensation, reimbursement or damages.

10.  Right to Refuse. Netscape will have the right to review the contents and
format of the Premier Graphic. If Netscape, in its sole discretion, at any time
determines that Premier Provider's Premier Graphic contains any material, or

reason, Netscape will inform Premier Provider of the reason Netscape has made
such determination and may (i) refuse to include the Premier Graphic in the
Page, and/or (ii) immediately terminate this Agreement if Premier Provider has
not revised to Netscape's reasonable satisfaction the Premier Graphic within one
(1) business day of written notice from Netscape. If Netscape, in its sole
discretion, at any time determines that the Premier Provider's Web Sites
contains any material, or presents any material in a manner, that Netscape deems
inappropriate for any reason, Netscape may immediately terminate this Agreement
upon notice to Premier Provider. Netscape reserves the right to refuse to
include the Premier Graphic in the Page if such Premier Graphic does not
completely conform to the specifications set forth in Exhibit 1.

11.  Capitalized terms defined in the Agreement shall have the same meaning in
this Addendum as in the Agreement.

12.  Except as explicitly modified, all terms, conditions and provisions of the
Agreement shall continue in full force and effect. For the purposes of Sections
15, 16, 17, 18.2 and 18.3 of the Agreement, the term "Service" shall include (i)
Premier Graphic, the Premier URLs, or the Premier Links, (ii) any material to

which users can link through any of the foregoing, or (iii) any use of Premier
Provider's search and directory service pursuant to this Agreement.

13.  In the event of any inconsistency or conflict between the Agreement and
this Addendum, the terms, conditions and provisions of this Addendum shall
govern and control.

14.  This Addendum and the Agreement constitute the entire and exclusive
agreement between the parties with respect to this subject matter. All previous

                                    EXHIBIT 1
                           SPECIFICATIONS OF THE PAGE

As of June 1, 1998, the Launch Date, Net Search will support Netscape Navigator
versions 2, 3 and 4 (on both the Macintosh and PC ("Wintel") platforms), and
Microsoft Internet Explorer 3.0 (PC only). (See Net Search Premier Graphics Test
Specification, External for complete list). All other browsers will be routed to
a simple version of the Page which encourages users to download a more current
version of Netscape's browser. Netscape will spend up to one hour of engineering
time per sampler per month to integrate a Premier Graphic into the Net Search
Page if available. If more engineering or QA time than is available becomes
necessary to fix bugs discovered, or if the necessary changes to fix any bugs
include changes to the appearance of the Premier Graphic, the Premier Graphic
will be returned for revision. The specifications are as follows:

[    Size. All Premier Provider materials should be exactly 468 by 165 pixels.
     Text and interactive forms included in the Premier Graphic should be of a
     default font size of 12 points. (Be aware, however, that text and forms may
     resize on your audience's browsers as they change their default font
     sizes.) Keep in mind that the [FONT SIZE=] tag is not implemented in early
     versions of web browsers.

A Premier Graphic is measured by taking a screen shot on a system configured
     as follows: A PC running Windows 95, with the settings configured for small
     fonts, and an NEC MultiSync XV17+ (17 inch) monitor. The screen shot will
     be taken of Netscape Navigator Gold version 3.1, with the Proportional Font
     set at 12pt Times New Roman, and the Fixed Font set at 10pt Courier New.
     The measurement will be taken in Paintbrush. Netscape will provide
     "measurement services", if needed, for companies that don't have the
     specified platform configuration.

     HTML Quirks. We have found a few less-than-obvious quirks which cause some
     browsers to crash, which we thought would be helpful to pass on:

     1.   [FORM] tags must follow IMMEDIATELY AFTER your sampler's first
          [TABLE] tag. Any variation of this whatsoever will cause a
          significant number of users to crash.
   
     2.   Any empty [TD] tags should be separated by a carriage return. HTML
          should read as follows: [TD]
          [/TD]
         as opposed to
         [TD][/TD]

     3.   If text appears without any spacing between words (for instance, in a
          sentence as opposed to in a table), any text that falls closer than 50
          pixels to the edge of the Premier Graphic should be tested on a Unix
          machine. Often, this text will be cut off on that platform.

     4.   Interleaving HTML tags will cause several browsers to crash. Tags
          should be ordered as follows: [H3][FONT COLOR="#000055"]Text
          here[/FONT][/H3] as opposed to [H3][FONT COLOR="#000055"]Text
          here[/H3][/FONT].

[         Tables. In order to maintain the robustness of the Page, please do not
          include any more than one nested table, for a total of two tables per
          sampler. Any more than one nested table will cause crashes for a
          significant number of users. One simple table is ideal, as even one
          nested table may cause some implementation problems when integrated
          with the Net Search Page. If you are nesting a table, please test
          carefully.

[         Image maps. Only a client-side image map is necessary, since browsers
          which don't support client-side maps will not be directed to the main
          Net Search Page.

[         File sizes. To keep the user's load time low, we request that Premier
          Provider files in total do not exceed 20K unless cleared by the U.S.
          Search production manager at [email protected].

[         Animated GIFs. Due to the large number of users whose browsers do not
          support animated GIFs, and their typically large file size, we are not
          implementing animated GIFs at this time.

[         JavaScript. JavaScript tends to cause older browsers to behave
          unpredictably and in many cases crash, and there is delicate
          technology in place to implement Site Sampler functionality. As a
          result, the implementation of Java Script in a Premier Graphic is not
          an option at this time. 

[         Delivery. Content providers should email files to Netscape at
          [email protected]. If you are providing multiple files, you
          should place them in a folder labeled with the content provider's
          name. For the best possible results, deliver a Premier Graphic that is
          already integrated into a copy of the Net Search Page. 

[         Filenames. It is important that filenames be in the following format:
          search_providername.fmt (for example, search_premprov.gif,
          search_premprov.htm). If there are two or more files of a certain
          format, filenames should be in the following format:
          search_providername#.fmt (for example, search_premprov.gif,
          search_premprov.gif). When you update your Premier Graphic, continue
          to increment the number to help avoid caching issues. 

[         Format. All content providers need to provide HTML files that include
          the layout for their materials. All HTML should be uppercase. Please
          include the TARGET="_top" attribute in all HREF tags. Height and width
          tags need to be specified for all images. Graphics files should be in
          GIF format; all other formats should be cleared with the Destinations
          production manager at [email protected].

[         Graphics. By limiting the number of individual graphics (server calls)
          in your Premier Graphic, you will improve overall Page performance and
          allow the Page to load more quickly. Cropping as close as possible to
          the image, leaving no white space around them, will also allow the 
          Page to load more quickly. To minimize dithering and insure that the
          users across all platforms see what you expect them to see, we
          recommend use of the Netscape Color Palette.

                                  No: 004327-2

This Amendment No. 2 (the "Amendment") is entered into by Netscape
Communications Corporation, a Delaware corporation, with its principal offices
at 501 E. Middlefield Road, Mountain View, California 94043 ("Netscape"), and
Excite, Inc., a California corporation, with principal offices at 555 Broadway,
Redwood City, CA 94063 ("Licensee") and effective as of the date of execution by
Netscape ("Effective Date").

WHEREAS, the parties have entered into a Netcenter Services Agreement effective
April 29, 1998 (the "Agreement");

WHEREAS, the parties have entered into Amendment No. 1 to the Netcenter Services
Agreement effective as of May 26, 1998 ("Amendment No. 1");

WHEREAS, the parties wish to modify and supplement the provisions of such
Agreement;

NOW, THEREFORE, the parties, in consideration of the terms and conditions
herein, agree as follows:

The parties agree to amend EXHIBIT G entitled Channel Allocation. The first
paragraph of EXHIBIT G shall be amended in its entirety as follows:

          "Both parties agree to use their best efforts to have the following
          Netscape Channels and Excite Co-Branded Channels up within 60 days
          after the Effective Date. The Launch Date shall occur on the first to
          occur of: (i) upon such date as the parties mutually agree, or (ii)
          the date when the following Channels are up:

               Netscape Channels: Small Business; Business News; Travel and
               Careers.

               Excite Co-Branded Channels: Games, Autos Shopping, Lifestyles and
               one of Real Estate, Auctions or Education, as such additional
               Co-Branded Channel shall be mutually agreed.

     The remaining Co-Branded Channels will be implemented within 6 weeks of the
     initial Launch Date or upon such date as the parties mutually agree. Excite
     shall use reasonable commercial efforts to launch the Interim Channels
     within 6 weeks of the Launch Date. Excite shall commit to providing at
     least four dedicated people to help achieve a timely launch and maintenance
     of the Service.

     The Netscape Branded Search Service shall also be launched on July 1, 1998
     or upon such date as the parties mutually agree."

     2.   Capitalized terms defined in the Agreement and Amendment No. 1 shall
          have the same meaning in this Amendment as in the Agreement and
          Amendment No. 1.

     3.   Except as explicitly modified, all terms, conditions and provisions of
          the Agreement and Amendment No. 1 shall continue in full force and
          effect.

     4.   In the event of any inconsistency or conflict between the Agreement,
          Amendment No.1 and this Amendment, the terms, conditions and
          provisions of this Amendment shall govern and control.

     5.   The Agreement, Amendment No. 1 and this Amendment constitute the

                               AMENDMENT NO. 3 TO
                          NETCENTER SERVICES AGREEMENT

                                  NO. 004327-3

This Amendment No. 3 ("Amendment") is entered into by and between Netscape
Communications Corporation, a Delaware corporation, with principal offices at
501 E. Middlefield Road, Mountain View, California 94043 ("Netscape"), and
Excite, Inc., a company organized under the laws of California, with principal
offices at 555 Broadway, Redwood City, CA 94063 ("Excite") and effective as of
the date of execution by Netscape ("Amendment Effective Date").

WHEREAS, the parties have entered into a Netcenter Services Agreement effective
April 29, 1998, as amended (the "Agreement"); and

WHEREAS, the parties wish to modify and supplement the provisions of the
Agreement;

NOW, THEREFORE, the parties, in consideration of the terms and conditions
herein, agree as follows:

1.   Section 3 of Exhibit B (Payment Terms) of the Agreement shall be amended in
     its entirety as follows:

          "3. Payment. Excite agrees that Netscape will earn as Netscape Revenue
          * per quarter. Amounts, once earned as Netscape Revenue, will no be
          available to offset amounts payable by Excite to Netscape in future
          periods. In addition, once Excite generates Revenue up to the point at
          which * % of Revenue in year one plus * % of Revenue in year two
          equals $ * million, Excite shall pay to Netscape * % of the Revenue,
          commencing from such date through the Term. Excite agrees to pay all
          Traffic Payments."

     In no event may this Amendment obligate Excite to pay additional amounts to
Netscape, nor may this Amendment results in an acceleration of any payments as
compared to the payments that would have been due under the terms of the
Agreement.

2.   Capitalized terms defined in the Agreement shall have the same meaning in
     this Amendment as in the Agreement.

3.   Except as explicitly modified, all terms, conditions and provisions of the
     Agreement shall continue in full force and effect.

4.   In the event of any inconsistency or conflict between the Agreement and
     this Amendment, the terms, conditions and provisions of this Amendment
     shall govern and control.

5.   This Amendment and the Agreement constitute the entire and exclusive
     agreement between the parties with respect to this subject matter. All
     previous discussions and agreements with respect to this subject matter are
     superseded by the Agreement and this Amendment.
