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

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,

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
Page, including, without limitation, any graphic designed by Netscape pursuant
to Section 3.1 or included by Netscape in the Net Search Program and any links
to the Netscape Branded Search Service from the Netcenter Widget, (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 *
and (v) be consistent with the overall look, feel and end user experience of
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
used in conjunction with the Excite brand, the * or * characters will not be
counted in the relative brand prominence. Excite agrees that the Netscape
Branded Search 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.

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

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

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

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.

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

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

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

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.

         6.5.4. Current Netscape * that fall into Excite channel areas will need
to be * into Excite's Co-Branded Channel for * . Excite will sell all other

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.

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

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

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
change its address for purposes hereof by written notice to the other in
accordance with the provisions of this Subsection.

19.5. Determination of Equivalence. Subject to Netscape's selection of Internet
search and Directory features or functionality pursuant to Section 3.1, the
parties agree that any obligation of Excite herein that is required to be
performed in a manner that is equivalent to, or otherwise commensurate with, the
same level of performance of the Excite Brand Service shall be deemed a material
obligation of Excite. Excite shall be deemed to be in material breach of any
such obligation in the event that the features and functionality of the Excite
Brand Service comparable to Netscape's selected Internet search and Directory
features or functionality pursuant to Section 3.1 shall at any time be rated
higher than Netcenter on * or more of the * , nationally recognized, * services.

19.6. Miscellaneous. (a) Neither party's waiver of a breach or delay or omission
to exercise any right or remedy shall be construed as a waiver of any subsequent
breach or as a waiver of such right or remedy. (b) This Agreement may be amended
only by a writing signed by both parties. (c) This Agreement creates no agency,
partnership, joint venture, or employment relationship and neither party nor its
agents have any authority to bind the other in any respect whatsoever. (d) All
rights not expressly granted by Netscape to Excite hereunder shall be reserved
by Netscape and all rights not expressly granted by Excite to Netscape hereunder
shall be reserved by Excite. (e) The section headings herein are used for
convenience only and shall have no substantive meaning. (f) In the event any
provision of this Agreement is held by a court or other tribunal of competent
jurisdiction to be unenforceable, such provision shall be reformed only to the
extent necessary to make it enforceable, and the other provisions of this
Agreement will remain in full force and effect. (g) Either party shall be
excused from any delay or failure in performance hereunder, except the payment
of monies by Excite to Netscape, caused by reason of any occurrence or
contingency beyond its reasonable control, including but not limited to, acts of
nature. The obligations and rights of the party so excused shall be extended on
a day-to-day basis for the period of time equal to that of the underlying cause

     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

     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.

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.

<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.

                                                                  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 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
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

<PAGE>   56

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

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

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.

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

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

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,

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.

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.

                           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
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

                                       10

<PAGE>   65

another person of all or substantially all of the assets of the Company (any of
the foregoing, a "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 shall 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 (i)
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.
