                  STRATEGIC DEVELOPMENT AND MARKETING AGREEMENT

This Strategic Development and Marketing Agreement (this "Agreement") is made
and entered into this 23rd day of November, 1998, by and between America Online,
Inc. ("AOL") and Sun Microsystems, Inc. ("Sun").

Certain terms used in this Agreement are defined in Section 24 hereof. This
agreement is confidential between the parties, provided that either party may
disclose the terms of this Agreement, and any associated collateral documents,
in order to comply with applicable laws and regulations, including securities
laws and regulations, and further provided that either party may disclose
information regarding portions of the financial provisions of this Agreement
after consulting with and obtaining the approval of the other party's Executive
Representative, which consent will not be unreasonably withheld or delayed. AOL
and Sun hereby agree as follows:

1.0 OBJECTIVES. AOL and Sun intend to cooperate in the development and marketing
of software and services in the area of electronic commerce and extended
communities and connectivity ("EC(2)") to businesses worldwide. The parties
intend to offer together an integrated, end-to-end solution including consumer
traffic, dial-up connectivity, network services, client software, server
software, computer systems, computer hardware, professional services, help desk
and service and support, but, subject to the terms and conditions herein, each
party would be free to offer its components in conjunction with competitive
components from third-parties. As described in this Agreement, some components
of such solution will be collaboratively developed, and some will be developed
principally or entirely by AOL or Sun. The solution offered by the parties is
expected to include traffic from AOL's multiple brands and related directory
services, configurable Netcenter or AOL.Com services and information, AOL
network access services, AOL instant messaging functionality, Sun support
services, Sun or AOL consulting services and Netscape or AOL outsourcing
services. As described in this Agreement, some components of such solution will
be marketed and sold by both parties pursuant to collaborative marketing and
sales plans, and some components would be marketed and sold by AOL or Sun only.
The business objectives of the parties include the following:

        1.1 Establish a cooperative relationship between AOL, the world's
        leading internet content provider, and Sun, the world's leading network
        computing platform supplier, to create and deliver the best, integrated,
        end-to-end enterprise commerce solutions using, where appropriate, the
        Java and Jini technology from Sun.

        3.5 NETWORK APPLICATION AND SERVER SOFTWARE. AOL and Sun will
        collaboratively develop the Network Application and Server Software, ***
        APPROXIMATELY 3 LINES OMITTED ***. AOL and Sun shall cooperate and
        coordinate their development efforts so that, to the extent commercially
        reasonable, the Client Software shall be compatible with and support the
        interfaces, protocols and APIs of the Network Application and Server
        Software in the Product Suites and vice versa.

        3.6 JAVA TECHNOLOGY. The parties agree to use reasonable efforts to
        modify the existing Netscape browser to develop the New Browser to
        incorporate, for each System Platform, the most current release
        available of the complete Java Runtime Environment (JRE) on all System
        Platforms for which Sun has a JRE available. The parties agree to use
        all reasonable efforts to ensure that Java code executing on the JRE so
        invoked has the same access privileges and capabilities as Java code
        running native on the operating system and can display user interfaces
        within the browser window consistent with the user experience of running
        Java applets today, provided that Sun provides such JRE to AOL, *** in
        binary form in a fully operational and commercially viable form. Without
        limiting the foregoing, AOL shall have no obligation to incorporate into
        any browser any JRE provided by Sun that fails to operate properly on
        the applicable System Platform for such version of such browser due to
        the fault of Sun or any party other than AOL, or *** or which would
        cause a material degradation in the performance characteristics of such
        browser relative to competitive browsers in the marketplace, or which
        cannot ***APPROXIMATELY 8 LINES OMITTED*** Without limiting the
        foregoing, with respect to the *** AOL shall have no obligation to
        ***APPROXIMATELY 3 LINES OMITTED*** Sun agrees to provide error
        corrections and bug fixes for the JREs on all supported System Platforms
        pursuant to its standard terms of support (but without fee to AOL). In
        the event Sun fails to provide such error corrections and bug fixes in a
        timely commercially reasonable manner, Sun shall, pursuant to the TLDA
        entered into between AOL and Sun, provide AOL with the source code, test
        suites and related development tools for such JREs and the right to use
        such source code, test suites and related development tools for the
        purpose of supporting and maintaining such JREs in accordance with the
        TLDA. Sun agrees to use reasonable efforts to *** In order to permit the
        binary JRE to be integrated into such browsers, AOL agrees to use
        reasonable efforts to incorporate and support the Open Java Interface in
        such browsers. AOL and Sun agree to collaborate and consult with one
        another and to cooperate with one another in good faith in an effort to
        define and integrate this interface into such browsers for use by the
        JREs in such browsers. AOL further agrees that if such incorporation of
        the JRE is successfully implemented in a version of such browser for any
        applicable System Platform, AOL will incorporate such version of such
        browser in the versions of the OEM Communicator Client, Third Party

        Client and AOL Distributed Communicator Client for such System Platform
        *** If the JRE is so incorporated in the OEM Communicator Client, Third
        Party Client or AOL Distributed Communicator Client, and AOL elects to
        distribute any version of such product via download, such version shall
        either be the JRE enabled version of such product, or AOL will make the
        JRE enabled version of such product available for download in addition
        to any non-JRE enabled version of such product made available for
        download. If the JRE is so incorporated in the OEM Communicator Client,
        Third Party Client or AOL Distributed Communicator Client, and AOL
        elects to distribute any version of such product via CD-ROM, the version
        of the product distributed by AOL via CD-ROM will be such JRE-enabled
        version, to the extent contractually permissible and subject to size
        limitations, and provided that AOL shall have no obligation to require
        that its OEMs include the JRE-enabled version. AOL shall have the right
        to distribute via download a smaller version of the New Browser without
        the JRE, provided such version has hooks that permit the user optionally
        to download and install the JRE. AOL will consider as part of the
        Collaborative Development Work Plans whether to expose to the JRE all
        public and private developer interfaces within the browser (including,
        without limitation those in NSHTML.DLL), but shall have no obligation to
        do so. AOL's obligations pursuant to this Section 3.6 are conditioned
        upon Sun's granting to AOL *** any rights to Java technology necessary
        to comply with this Section 3.6. In the event of any inconsistency or
        conflict between this Section 3.6 or Section 9.8.1 of this Agreement and
        the TLDA entered into between Sun and AOL, the terms of this Section 3.6
        and the terms of Section 9.8.1 shall control.

        3.7 INTENT TO DEVELOP LEADING PRODUCTS. The parties agree to use their
        reasonable efforts to maintain the existing Netscape browser and the New
        Browser as competitive alternatives to the browser component of Internet
        Explorer from Microsoft, and agree that it is their intention to make
        all products developed and distributed pursuant to this Agreement
        leading and competitive products in their respective product categories.

        3.8 JRE BUNDLING ON CD-ROMS. On any CD-ROMs on which AOL ships the AOL
        classic client and on which AOL provides installation options permitting
        third party software other than AOL classic client software to be a
        separate installable item, ***APPROXIMATELY 3 LINES OMITTED*** AOL
        agrees, subject to any third party contractual limitations, to use
        reasonable efforts to co-package the latest version of the JRE with such
        client and to offer to users an installation option to install such JRE,
        provided that the JRE meets commercially reasonable standards making it
        suitable for inclusion and installation, including without limitation
        reasonable quality assurance and size limitations. AOL shall have no
        obligation to display such installation option until after

        3.10 THIRD PARTY COMPONENTS AND PROTOCOLS; DIVERGENCE OF DEVELOPMENT. In
        the event AOL (i) elects to use third party software or technology for
        core functionality and features of the browser component of any of the
        Client Software, (ii) adopts and maintains protocols or interfaces that
        are inconsistent with Sun's reasonable server-dictated requirements; or
        (iii) fails to support protocols or interfaces that are reasonably
        required by Sun's server-dictated requirements, Sun shall have the
        right, but not the obligation, to have AOL provide to Sun the source
        code, test suites, and related development tools reasonably required for
        Sun to pursue independent development of a browser based on the Existing
        Netscape Software and/or Collaborative Software and to create client
        applications incorporating such independently developed Sun browser. Any
        resulting products developed by Sun shall be deemed to constitute
        Designated Collaborative Software for purposes of this Agreement.

4.0     SALES AND MARKETING.

        4.1     CUSTOMERS.

                4.1.1   GENERAL. In accordance with the Marketing and Sales
                        Plan, the parties will work together to actively market
                        Product Suites, as well as other related products,
                        including Sun, Netscape, and AOL products and services,
                        to customers.

                4.1.2   AOL COMMITTED SALES FORCE. Sun acknowledges that AOL
                        intends to commit an AOL sales force to target sales by
                        AOL to AOL EC Service Opportunities. Such sales force
                        may consist of (i) AOL interactive marketing sales
                        personnel and (ii) the current Netscape Netcenter sales
                        personnel. AOL shall bear all costs of such committed
                        sales force. Sun shall provide reasonable assistance to
                        AOL, as reasonably requested by AOL from time to time,
                        in connection with this AOL committed sales effort. Sun
                        shall provide such assistance through the sales and
                        marketing resources that Sun is required to provide
                        pursuant to the provisions of Section 4.1.3 and the
                        Marketing and Sales Plan, which may include access to
                        and participation of Sun employees who are not part of
                        the collaborative

                        acknowledges that AOL intends to maintain a professional
                        services group to support AOL EC Services Opportunities
                        independent of any persons providing collaborative
                        services pursuant to this Agreement.

                4.1.3   COLLABORATIVE SALES. AOL and Sun shall each form their
                        own respective sales forces targeting sales of the
                        Product Suites to non AOL EC Service Opportunities. The
                        AOL collaborative sales force shall consist of AOL and
                        Netscape enterprise sales and marketing, professional
                        services and technical support personnel selected by
                        AOL. The Sun collaborative sales force shall consist of
                        Sun sales personnel selected by Sun. The AOL and the Sun
                        collaborative sales forces shall both sell only off a
                        common pricelist and on standard terms and conditions,
                        with such pricelist and terms and conditions to be
                        designated by the Lead Executive for marketing and
                        sales. Each of AOL and Sun will, as specified in the
                        Marketing and Sales Plan, commit specified target levels
                        of sales and marketing resources (personnel and a
                        portion of marketing budget) to the staffing and support
                        of their respective collaborative sales forces and
                        coordinate the efforts of their respective collaborative
                        sales forces. In addition, Sun will support the
                        collaborative sales activities of the AOL collaborative
                        sales force with respect to any Sun products and
                        services, which may include access to and participation
                        of Sun employees who are not part of the collaborative
                        team, such as Sun technical personnel, and AOL will
                        support the collaborative sales activities of the Sun
                        collaborative sales force with respect to AOL Services
                        Offerings, which may include access to and participation
                        of AOL employees who are not part of the collaborative
                        team, such as AOL technical personnel.

                4.1.4   SHARING OF REVENUES COLLECTED FROM CUSTOMERS. Subject to
                        the provisions of Section 4.2, revenues from the sale or
                        license of products or services shall be shared as set
                        forth below. Each party acknowledges that these
                        provisions are intended to reflect how revenues are
                        allocated and are not controlling as to which revenues
                        are recognized by which parties, which recognition shall
                        be at the sole discretion of each party in accordance
                        with Generally Accepted Accounting Principles.

                                SERVICES. AOL will receive 100% of the revenues

        4.2     ADDITIONAL REVENUE DETERMINATION AND ALLOCATION PROVISIONS

                        appropriate revenue or Gross Margin allocation under
                        Section 4.1.4, in cases where a single product or
                        service is sold, the revenues received shall be deemed
                        to equal the gross revenues (before sales commission)
                        collected from the end user or the OEM customer and the
                        Gross Margin shall be calculated in accordance with

                        services are sold in a bundled sale, the revenues per
                        product or service will be calculated by computing the
                        overall discount (or ***, whichever is lower) from list
                        price for the bundled sale (or the aggregate sum of the
                        list prices for each individual component in the bundled
                        sale, if there is no list price for the bundled sale)
                        and applying that discount to the list price for the
                        product. *** APPROXIMATELY 10 LINES OMITTED ***.

                        As used in this Section 4.2.2, the term "existing
                        contracts" shall mean any contracts entered into on or
                        before the Closing Date for the duration of the
                        remaining term of such contracts as well as any
                        extensions or renewals of the term of such contracts to
                        the extent the customer or OEM elects to exercise any
                        unilateral right of extension or renewal contained in
                        such existing contracts. AOL and Sun each shall retain
                        their existing customer contracts for the Netscape
                        client software, with all service, maintenance and
                        support provided by AOL, to the extent Netscape is
                        obligated to provide such service, maintenance and
                        support under existing service, maintenance and support
                        agreements, and all service, maintenance and support
                        provided by Sun, to the extent Sun is obligated to

                        existing service, support and maintenance agreements.
                        AOL and Sun will each have the right to fulfill its
                        respective obligations under existing contracts,
                        notwithstanding anything to the contrary contained in
                        this Agreement

        activities, Sun shall prioritize the marketing of the following client
        products, where they exist for the customer platform, in the following
        manner:

                (a) As part of the standard Product Suites offering and any
                other time Sun is marketing, distributing or selling a browser
                component, Sun will give first priority to the marketing and
                sale of ***.

                (b) If a customer indicates that it does not want ***,Sun will
                next attempt to market and sell ***.

                (c) If a customer indicates that it does not want ***, Sun will

        *** APPROXIMATELY 7 LINES OMITTED ***

        4.4 AOL SERVICE COMPONENTS AND SERVICE OFFERINGS. AOL and Sun each

        Without limiting the foregoing, Sun will actively market, promote and
        support the AOL Service Components and AOL Service Offerings that are
        incorporated into products comprising the Product

        Suites in connection with its marketing, promotion and sales of the
        Product Suites, provided that Sun customers will not be required to use
        or maintain any AOL Service Components included in the Product Suites.
        Notwithstanding anything to the contrary herein, including without
        limitation the provisions of Section 4.1.4, AOL shall retain all
        collected revenues related to or derived from sales or licenses of AOL
        Service Components and AOL Service Offerings. Neither Sun nor the
        collaborative sales team shall have any right to sell any AOL Service
        Offerings without AOL's prior written consent, and AOL shall have no
        obligation to provide such consent.

        4.5 MINIMUM REVENUE COMMITMENTS BY SUN. Sun will commit that, during the
        term of this Agreement, the total of the net amounts paid per year to
        AOL under Sections, 4.1.4.2, 4.1.4.4, 9.6.2 (including, without
        limitation, net of commissions payable to Sun sales personnel) and under
        4.2.2 (which includes revenues derived by AOL from the sale of Existing
        Netscape Software and Existing Netscape Software Upgrades and Associated
        Services), will be not less than Three Hundred Twelve Million Dollars
        ($312,000,000) for the first year following the Closing Date, Three
        Hundred Thirty Million Dollars ($330,000,000) for the second year
        following the Closing Date, and Three Hundred Thirty Three Million Two
        Hundred Fifty Thousand Dollars ($333,250,000) for the third year
        following the Closing Date, payable in quarterly minimum payments the
        ("Minimum Commitment") as set forth in Section 8.1.

        4.6 PENETRATION RATE FOR BUSINESS DESKTOP. So long as certain specified
        milestone deliverable dates are satisfied as set forth in the
        Collaborative Development Work Plans, Sun shall use all reasonable
        efforts to achieve penetration of enterprise desktops by the Third Party
        Communicator Client and AOL Distributed Communicator Client as set forth
        in the Marketing and Sales Plan as mutually-agreed in writing prior to
        the Closing Date, including without limitation bundling the Third Party
        Communicator with Sun's Solaris operating system, actively promoting the
        Third Party Communicator on Sun's website, and such other actions as Sun
        normally takes to promote and market its products, provided that Sun
        shall be relieved of such obligations to achieve such penetration if Sun
        embarks on a divergent development path with respect to the Third Party
        Communicator Client pursuant to Section 3.10. If the agreed level of
        penetration is not achieved, Sun will take reasonable steps (e.g.,
        increased marketing, promotion and salesforce incentives) to increase
        the penetration rate to the required level within six months; provided
        that, if Sun believes that the failure to achieve the requisite level of
        penetration was due to factors beyond its reasonable control and/or that
        the penetration rate shortfall cannot reasonably be remedied through
        increased marketing and promotion unless additional remedial action is
        also taken during such six month period, Sun will so inform AOL and the
        parties shall discuss Sun's concerns and attempt to agree through good
        faith negotiation on an appropriate plan to increase the penetration
        rate within such six month period. Such plan may include actions by Sun
        and/or AOL, depending on the circumstances. The Executive
        Representatives shall facilitate such negotiation. If either

        Executive Representative believes that negotiation will not succeed in a
        timely fashion, he or she may refer such dispute to the two chief
        executive officers to resolve. The Incentive Plan referred to in Section
        13.1 will set forth the method by which Sun will provide incentives to
        its sales force to achieve the requisite penetration rate. The
        escalation procedures set forth in this Section 4.6 shall constitute
        AOL's sole and exclusive remedy for any failure to achieve the specified
        target penetration rate.

        4.7 MARKETING AND SALES PLAN. The Marketing and Sales Plan will set
        forth a detailed description of how the two sales and marketing teams
        (i.e., the sale forces described in Sections 4.1.2 and 4.1.3,
        respectively) will collaborate, including the initial sales force
        compensation and incentive plans (as further described in Section 13.1)
        to be implemented independently by the parties, the goal of which will
        be to provide appropriate incentives for the sales forces to meet and
        exceed the Minimum Commitments.

        4.8 WARRANTIES, INDEMNIFICATION AND SUPPORT. Sun shall have the
        exclusive right to provide and will provide all warranty and support
        services in connection with sales and licenses (other than pursuant to
        existing contracts as set forth in Section 4.2.2) by the collaborative
        sales force and by the dedicated AOL sales force of the Product Suites,
        including warranty and support services for supported Systems Platforms
        other than the Sun Systems Platform, which may include Systems Platforms
        such as Windows NT, HP-UX, Linux and IBM AIX. Sun will fulfill warranty
        and support obligations in connection with all sales and licenses by AOL
        arising from sales by the collaborative sales force and by the dedicated
        AOL sales force of the Product Suites (other than pursuant to existing
        contracts as set forth in Section 4.2.2). In consideration of Sun's
        providing such support services, AOL will pay to Sun the sum of One
        Million Dollars ($1,000,000) per month during the term of this
        Agreement. In addition, Sun will, at the request of AOL, fulfill
        warranty and support obligations for existing contracts as set forth in
        Section 4.2.2 ***. Such support services shall include frontline
        technical support, including call receipt, call screening, installation
        assistance, problem identification and diagnosis, and other standard
        support services customarily provided by Sun's twenty-four hour per day,
        seven day per week support center. Backline escalation support shall be
        provided by the collaborative development team. Sun shall defend,
        indemnify and hold AOL harmless from all third party claims and
        allegations relating to alleged breach or failure to provide support
        services or breach of support service obligations under Sun's standard
        maintenance contracts under which it is obligated to support the Product
        Suites. AOL will promptly notify Sun in writing of any such claim or
        allegation giving Sun the sole right of defense and settlement, and will
        assist Sun, at Sun's expense (except for the value

        AOL shall have the right to employ separate counsel and to participate

                        Executive shall be assigned by the party other than the
                        party employing the Lead Executive, after consultation
                        with the Lead Executive. Each party shall structure all
                        employees and resources for each MC under the Lead
                        Executive or Deputy Lead Executive for that MC, and the
                        Lead and Deputy Lead Executives and project leaders
                        shall direct such resources in accordance with and to
                        achieve the objectives of the Collaborative Development

                5.3.3   CLIENT SOFTWARE. The initial Lead Executive for the
                        Client Software MC shall be Barry Schuler. The Lead
                        Executive for the Client Software MC shall have the
                        right, after consultation with the Deputy Lead
                        Executive, to make all decisions with respect to the
                        design and development of the Client Software and the
                        New Browser, including without limitation the features
                        and functions to be included in each such product design
                        and all decisions regarding development priorities and
                        resource allocation.

                        Lead Executive for the Network Application and Server
                        Software MC shall be Ed Zander. As part of the
                        Collaborative Development Work Plans, with the consent
                        of each party through its Lead Executive or Deputy Lead
                        Executive, which consent shall not be unreasonably
                        withheld or delayed, the Lead Executive will establish
                        mutually agreeable targets for development of the
                        Network Application and Server Software. It is AOL's
                        present intention not to replace the initial Lead
                        Executive for Network Application and Server Software
                        unless such development targets are missed in a material
                        fashion, but AOL shall have the right, after
                        consultation with Sun, to replace the Lead Executive for
                        the Network Application and Server Software MC at any
                        time after the Closing Date. The Lead Executive for the
                        Network Application and Server Software may be an
                        employee of either party. In selecting the project
                        leader and team leaders for various development projects
                        to be undertaken in the development of the Network
                        Application and Server Software, the Lead Executive for
                        the Network Application and Server Software shall
                        appoint a significant number of AOL employees as project
                        and/or team leaders.

                5.3.5   COLLABORATIVE DEVELOPMENT WORK PLANS. Prior to the
                        Closing Date, the Lead Executive and Deputy Lead
                        Executives shall establish and attach

                        hereto as Schedule 5.3 the initial Collaborative
                        Development Work Plans for the two MCs of the initial
                        Collaborative Development Activity (consisting of an MC
                        for Client Software development and an MC for Network
                        Application and Server Software development), setting
                        forth the objectives, principal deliverables of each
                        such MC and providing for priorities in going forward.
                        Changes to the principal deliverables or priorities
                        sections of the Collaborative Development Work Plan for
                        Network Application and Server Software shall require
                        the consent of both parties not to be unreasonably
                        withheld or delayed, but all other changes to such
                        Collaborative Development Work Plans may be made by the
                        Lead Executive for the applicable MC after consultation
                        with the Deputy Lead Executive for such MC. In making
                        such changes, the Lead Executive must act solely in
                        accordance with the terms and objectives of this
                        Agreement.

                5.3.6   CROSS PLATFORM DEVELOPMENT. Understanding that it is the
                        parties' intention to offer cross platform solutions,
                        the parties shall, to the extent commercially
                        reasonable, develop the Client Software and the Network
                        Applications and System Software to operate on a variety
                        of System Platforms, including the Sun System Platform
                        as well as other Systems Platforms including Windows NT,
                        IBM AIX, Linux, HP-UX and other Systems Platforms. Any
                        decision to support a platform other than Solaris or
                        Windows NT shall require a financial analysis showing a
                        reasonably appropriate return on investment, and in all
                        cases all Collaboratively Developed Software at the date
                        of first customer shipment must ship on Solaris.

                5.3.7   NON-DISCLOSURE; LIMITATIONS ON WORK ON OTHER
                        DEVELOPMENT. All individuals engaged in Collaborative
                        Development Activities will be prohibited from using or
                        disclosing any confidential information or trade secrets
                        learned or developed in the course of such Collaborative
                        Development Activities other than in the course of their
                        work on the Collaborative Development Activities or
                        their work for AOL or Sun, respectively. AOL and Sun
                        each acknowledges that the parties may have to establish
                        procedures and/or enter into supplemental
                        confidentiality agreements to address issues that may
                        arise in connection with Collaborative Development
                        Activities, such as, by way of example, the use of
                        confidential information of third parties which one
                        party may not have the right to disclose to the other
                        party. In addition, AOL and Sun each agrees that after
                        it has assigned developers to the Collaborative
                        Development Activities, it shall use reasonable efforts
                        to keep such individuals assigned to the Collaborative
                        Development Activities, and

                        AOL and Sun each agrees that it will not reassign
                        multiple employees engaged in the Collaborative
                        Development Activities to work on similar or competitive
                        development activities for other customers, clients, or
                        strategic partners. If AOL or Sun reassigns an
                        individual employee to work on similar or competitive
                        development activities for a customer, client, strategic
                        partner or other third party, such party to this
                        agreement shall advise the customer, client, strategic
                        partner or other third party that such employee was
                        involved in similar or competitive development
                        activities pursuant to this Agreement and that such
                        individual is subject to a confidentiality and
                        non-disclosure agreement prohibiting such individual
                        from using or disclosing any confidential information or
                        trade secrets learned or developed in the course of such
                        Collaborative Development Activities.

                5.3.8   PROTECTION OF SOFTWARE. AOL and Sun will agree on
                        procedures so that development is conducted in a such a
                        manner that AOL Service Components, other AOL and
                        Netscape proprietary software, Sun software, and the
                        Collaborative Software are not inadvertently placed in
                        the public domain or required to be publicly disclosed
                        pursuant to the Mozilla Public License or Netscape
                        Public License. Both parties shall comply with such
                        procedures, and notwithstanding anything to the contrary
                        contained in this Agreement, in no event may a Lead
                        Executive make any decision to implement development in
                        a manner inconsistent with such procedures without the
                        written consent of both AOL and Sun, which either party
                        may withhold in its sole discretion.

        5.4     MANAGEMENT PROCESS FOR SALES AND MARKETING.

                5.4.1   MARKETING AND SALES PLANS. An initial draft of the
                        Marketing and Sales Plan for the Collaborative Marketing
                        and Sales Activity will be mutually agreed upon prior to
                        the Closing Date by the Lead Executive and Deputy Lead
                        Executive for marketing and sales, setting forth the
                        objectives and targets, and principal methods for
                        marketing and sales of the Product Suites and components
                        thereof. Major substantive changes to such initial
                        Marketing and Sales Plan shall require the consent of
                        both parties, such consent not to be unreasonably
                        withheld, but any minor changes may be made by the
                        corresponding Lead Executive after consultation with the
                        Deputy Lead Executive. In making such changes, the Lead
                        Executive must act solely in accordance with the terms
                        and objectives of this Agreement. The Lead Executive and
                        Deputy Lead Executive shall not be changed prior to the
                        Closing Date.

                        Executive for Marketing and Sales shall maintain and
                        revise the Marketing and Sales Plan in accordance with
                        its terms. For each Lead Executive there shall be a
                        Deputy Lead Executive. The Deputy Lead Executive shall
                        be assigned by the party other than the party employing
                        the Lead Executive. The Lead Executive for Marketing and
                        Sales, after consultation with the Deputy Lead Executive
                        for Marketing and Sales, shall have the right to
                        establish projects and teams and project and team

                        Marketing and Sales Plan. Each party shall structure all
                        employees and resources of such party's respective
                        collaborative sales team under the Lead Executive or
                        Deputy Lead Executive, and the Lead Executive and Deputy
                        Lead Executives and their subordinates shall direct such
                        resources in accordance with and to achieve the
                        objectives of the applicable Marketing and Sales Plan.

                5.4.3   LEAD EXECUTIVES. The initial Lead Executive for

                        for marketing and sales of the Product Suites. It is
                        AOL's present intention not to replace the initial Lead
                        Executive for Marketing and Sales unless such targets
                        are not met, but AOL shall have the right, after
                        consultation with Sun, to replace the Lead Executive for
                        Marketing and Sales at any time after the Closing Date.
                        In the event replaced, the Lead Executive and Deputy
                        Lead Executive may only be replaced by a person of
                        similar rank and stature unless the parties otherwise
                        agree. The Lead Executive for Marketing and Sales must
                        be an employee of either AOL or Sun.

                5.4.4   COORDINATION. The AOL collaborative sales force and the
                        Sun collaborative sales force shall coordinate their
                        sales efforts and endeavor to cooperate with one another
                        to achieve maximum sales of the Product Suites in

                5.4.5   CROSS PLATFORM MARKETING AND SALES. The collaborative
                        sales forces of AOL and Sun will be trained and

        only to enable such opportunities. In sales to AOL EC Service
        Opportunities made by AOL personnel, AOL may elect to have the sales and
        licensing agreements for the goods and services sold be between the
        customer and AOL or may elect to have such agreements be between Sun and
        the customer. AOL shall have the unrestricted right to market and
        distribute the Client Software and New Browser during and after the term
        of this Agreement in any manner whatsoever, including without limitation
        through OEM licensing arrangements.

        6.2 SUN. During the term of this Agreement, Sun will have the right to
        market, including through reseller and OEM arrangements, the
        Collaborative Software through the Collaborative Marketing and Sales

        provisions of Section 4.1.4.

        6.3 SUN DEVELOPMENT. Subject to the provisions of Sections 6.6 and 6.7,
        Sun is free to develop at its own expense additional client, server and
        application software, functionality and features for EC(2). Any such
        software developed by Sun independently which is not a derivative work
        of the Existing Netscape Software or the Collaborative Software and was
        not developed pursuant to any Collaborative Development Work Plan shall
        not constitute Collaborative Software or Designated Collaborative
        Software, and Sun shall own such independent developments and all
        proprietary rights therein.

        6.4 AOL DEVELOPMENT. AOL is free to develop at its own expense and to
        collaborate with one or more third parties in developing additional
        client, server and application software, and functionality and features
        for electronic commerce and extended communities and connectivity,
        including without limitation software based on and derived from the
        Existing Netscape Software. Any such software developed by AOL
        independent of any Collaborative Development Work Plan shall not
        constitute Collaborative Software or Designated Collaborative Software,
        and AOL shall own such independent developments and all proprietary
        rights therein.

        6.5 REPLACEMENT OF IE BROWSER. To the extent contractually permissible,
        AOL will periodically evaluate replacing the browser component of
        Microsoft Internet Explorer browser with the New Browser in the AOL
        classic online service offering and to use the New Browser in clients
        for other brands such as ICQ and CompuServe, provided that the parties
        acknowledge that AOL has no present intention to make any such
        replacement or use and shall have no obligation to make any such
        replacement or use, and that it is AOL's present expectation that it
        will not seek to terminate or limit its present agreement

        6.6 NO DEVELOPMENT OR MARKETING OF COMPETITIVE CLIENTS. Except as
        provided in Section 3.10, for any System Platform for which AOL
        implements, in the OEM Communicator Client and Third Party Communicator
        Client, the most recent version of Sun's JRE pursuant to Section 3.6,
        Sun shall not during the term of this Agreement, directly or indirectly
        through any third party, develop, market, advertise, or distribute any
        software product or assist in advertising, marketing, or distributing
        any software product on such System Platform (including without
        limitation any other browser component) including or bundled with
        features and functions which make it competitive with a desktop client
        such as the client for the AOL classic online service, AOL Distributed
        Communicator Client, the Third Party Communicator Client, the OEM
        Communicator Client or Microsoft Internet Explorer (as it continues to
        evolve away from a browser to a fully featured online desktop
        client),*** APPROXIMATELY 11 LINES OMITTED *** This Section 6.6 shall
        not be deemed to limit or prohibit Sun from continuing to develop,
        market, advertise, promote and distribute browsers that are 100% Pure
        Java or are for platforms other than personal computers or workstations,
        subject to the provisions of Section 4.3, nor from continuing to
        develop, market and promote client software other than browsers except
        as provided in this Section.

        6.7 SUPPORT FOR PRODUCT SUITES STANDARDS. It is the intention of the
        parties that all client software will support industry-standard
        protocols and the standards, protocols and defaults in the Product
        Suites, including without limitation the standards, protocols and
        defaults of the AOL Services Components in the Product Suites, and
        except as provided in Section 3.10, Sun agrees not to implement, in the
        Sun Systems Platform or in other software competitive with or offering
        similar functionality to the Product Suites, inconsistent or conflicting
        standards, protocols or defaults, including without limitation
        inconsistent or conflicting with the components, features,
        functionality, interfaces, protocols and APIs of the New Browser.

        6.8 IMPACT OF LICENSE TO COMPETING OEM. If, during the term of this
        Agreement, AOL grants an OEM license to any of the network application
        and server software comprising the Existing Netscape Software or any
        derivative works thereof developed by

        large sum or advance pursuant to such an agreement, the reduction
        arising from such amount shall be applied pro rata across all then
        remaining quarterly Minimum Commitments.

        6.9 LICENSES BY SUN. During the term of this Agreement, Sun shall
        structure its license transactions for the Existing Netscape Software
        and Designated Collaborative Software so that the revenues to Sun ***
        and Sun shall not enter into licenses for such software intending to (a)
        have a material adverse impact on the penetration rate for the business
        desktop as set forth in Section 4.6 or (b) materially reduce the amounts
        payable to AOL hereunder.

        6.10 RESOURCES. AOL and Sun shall each provide a minimum level of
        staffing through their respective collaborative sales forces, as set
        forth in the Marketing and Sales Plan, to achieve the objectives of the
        SE's, and AOL and Sun shall each provide a minimum level of development
        staffing, as set forth in the initial Collaborative Development Work
        Plans, to achieve the objectives of the Network Application and Server
        Software development MC. Sun shall be responsible for using all
        reasonable efforts at its expense to provide whatever remaining
        resources are needed to achieve the goals of each SE as set forth in the
        Marketing and Sales Plan and to achieve the goals set forth in the
        Collaborative Development Work Plan for Network Application and Server
        Software, but in no event will Sun be required to provide more than the
        maximum levels of Sun staffing set forth in the Marketing and Sales Plan
        and the Collaborative Development Work Plan for Network Application and
        Server Software. Sun will provide a level of staffing for Sun's
        collaborative sales force at least as large as that of AOL's
        collaborative sales force, and Sun shall provide a level of staffing for
        the Collaborative Development Activities at least as great as the
        staffing AOL provides for the Collaborative Development Activities.
        Either party may reduce its level of staffing if such party concludes
        that then current and reasonably anticipated business conditions no
        longer justify then current staffing levels. In the event the aggregate
        level of staffing provided by AOL in any quarter for Collaborative
        Development Activities and Collaborative Marketing and Sales Activities
        is less than ***, the otherwise applicable Minimum Sales Commitment for
        the next quarter shall be reduced by *** per person for such shortfall

        7.1 GENERAL. The parties shall attempt to promptly resolve through good
        faith negotiation any dispute or disagreement between them directly
        relating to design and development priorities and decisions and resource
        allocation under the Collaborative Development Work Plan for Network
        Application and Server Software and marketing and sales priorities and

8.0     PAYMENT TIMING PROVISIONS.

        8.1 TIMING. Fees payable pursuant to Section 4.1.5, 4.5 and 9.8.2 shall
        be paid quarterly in advance not later than the fifth business day of
        the quarter for which due, except that amounts payable pursuant to such
        Sections for the first quarter shall be paid on the Closing Date, and,
        in the event to first quarter is not a complete quarter, amounts payable
        pursuant to such Sections for the first partial quarter and the first
        full quarter shall be payable on the Closing Date. Unless otherwise
        specified, other fees shall be paid no later than 45 calendar days after
        the end of the quarter for which due (including fees in excess of the
        minimum amounts due with respect to any quarter). No fees are payable
        until the quarter in which the Closing Date occurs, and any fees for
        that quarter, including minimum quarterly fees specified in this
        Agreement, including in Sections 4.1.5, 4.5 and 9.8.2, shall be a pro
        rata amount based on the number of days remaining in such quarter. In
        the event the first quarter is not a complete quarter (i.e., the Closing
        Date occurs other than at the beginning of the quarter), any reductions
        in minimum revenues or other fees specified in this Agreement, including
        in Sections 4.1.5, 4.5 and 9.8.2, shall not apply until the second full
        quarter. For partial quarters at the beginning and the end of each year
        of the term of this Agreement, the quarterly amount payable shall be a
        prorated portion of the full quarterly amount specified for such year,
        based on the number of days in such partial quarter period. (For
        example, if the first anniversary of the Closing Date is March 20, 2000,
        the prorated Minimum Commitment payable pursuant to Section 4.5 for the
        partial period running from January 1, 2000 through March 20, 2000 shall
        be the applicable prorated portion of $78,000,000, which amount shall be
        due and payable on January 1, 2000, and the prorated Minimum Commitment
        for the partial period running

        prorated portion of $82,500,000, which amount shall also be due and
        payable on January 1, 2000.

        8.2 NO RIGHT TO WITHHOLD OR OFFSET. Sun will have no right whatsoever to
        withhold payment of any minimum fees or revenues provided for in
        Sections 4.1.5, 4.5 or 9.8.1 on the basis of any alleged right of offset
        or any alleged breach by AOL of any of its obligations pursuant to this
        Agreement or for any other reasons except to the extent permitted
        pursuant to a final, non-appealable judgment obtained from a court of
        competent jurisdiction in litigation between AOL and Sun.
        Notwithstanding anything to the contrary set forth in this Agreement, in
        the event Sun believes that AOL has breached any obligations under this
        Agreement, Sun shall have no right to cease paying any such minimum fees
        and revenues, even if Sun has terminated or purported to terminate this
        Agreement, and Sun's sole and exclusive remedy shall be to litigate the
        dispute and to continue making such payments during the pendency of the
        litigation. AOL shall be entitled to injunctive relief to compel Sun to
        continue making such payments during the pendency of such litigation.

        8.3 LATE CHARGES. In the event that either party does not receive any
        amounts from the other party hereunder on or before the day upon which
        such amounts are due and payable, and fails to cure such breach within
        ten (10) business days following written notice from the other party,
        such outstanding amounts shall thereupon be subject to payment of a late
        charge which shall accrue until payment at the rate of one percent (1%)
        per month. Amounts received by shall first be credited against any
        unpaid late charges accrued pursuant to this Section, and accrual of
        such late charges shall be in addition to and without limitation of any
        and all additional rights or remedies under this Agreement or at law or
        in equity.

9.0     INTELLECTUAL PROPERTY RIGHTS.

        9.1 OWNERSHIP. Each party shall own all preexisting software and/or
        technology which it makes available to the Collaborative Development
        Activity or which it developed or develops with its own resources
        without use of any intellectual property of the other party and not as
        part of the Collaborative Development Activities and all proprietary
        rights therein. To the extent such software and/or technology is
        incorporated into the Designated Collaborative Software, it shall, to
        the extent so incorporated, be subject to the provisions of Sections
        9.2, 9.3 and 9.4.

        9.2 DESIGNATED COLLABORATIVE SOFTWARE. AOL shall own all improvements
        and modifications to any preexisting software or technology of either
        party, any new software and technology created through Collaborative
        Development Activity to create the Client Software and/or New Browser,
        and all newly-created intellectual property rights therein, whether
        completed or work in progress. Sun shall own all improvements and
        modifications to any preexisting software of either party and any new
        software and

        the Network Application and Server Software and all newly-created
        intellectual property rights therein.

        9.3 AOL LICENSE TO SUN. AOL hereby grants to Sun and its subsidiary, Sun
        Microsystems International, B.V. ("Sun International B.V.") a Software
        License to all Designated Collaborative Software owned by AOL pursuant
        to Sections 9.1 and/or 9.2, subject only to the payment by Sun of the
        amounts provided in this Agreement. Such license shall be unrestricted
        as to field of use, except for those limitations set forth in Section
        6.6 and 6.7. AOL also hereby grants to Sun a non-exclusive, perpetual,
        non-terminable, fully sublicensable right under any patents issued
        anywhere in the world for which AOL is or becomes the beneficial or
        legal owner which were reduced to practice in the course of the
        Collaborative Development Activity to make, have made, practice, have
        practiced, use, lease, sell and otherwise transfer any and all
        inventions, methods or processes which are the subject of any claim of
        any such patent.

        9.4 SUN LICENSE TO AOL. Sun shall grant to AOL a Software License to all
        Designated Collaborative Software owned by Sun pursuant to Sections 9.1
        and/or 9.2, whether written in Java or any other programming language.
        Such license shall be unrestricted as to field of use. Notwithstanding
        the foregoing grant to AOL, AOL's rights to the Java Platform shall be
        governed solely by the TLDA executed concurrently herewith by the
        parties. Sun also hereby grants to AOL a non-exclusive, perpetual,
        non-terminable, fully sublicensable right under any patents issued
        anywhere in the world for which Sun is or becomes the beneficial or
        legal owner which were reduced to practice in the course of the

        any such patent.

        9.5 PROCEDURES FOR LITIGATING PROPRIETARY RIGHTS CLAIMS AGAINST THIRD
        PARTIES. AOL and Sun agree to cooperate with one another and to
        negotiate in good faith procedures and terms and conditions permitting
        each party to pursue infringement claims against third parties with
        respect to the Designated Collaborative Software and other rights
        licensed to one another pursuant to this Agreement. The parties will
        consider and discuss whatever arrangements might most efficiently and
        fairly permit such actions to be pursued, which might include, by way of
        example, an assignment of an undivided joint interest in the software at
        issue in order to confer standing to sue on the party seeking to bring
        such action, an agreement by which the other party is joined as a party
        plaintiff in the action with provisions allocating the responsibilities
        and costs of litigating such claims, or some other mechanism.

                9.6.1   LICENSE FOR DEVELOPMENT. As of the Closing Date, as
                        between AOL and Sun, AOL shall own all rights in and
                        shall grant to Sun a Software License to the Existing

                        Upgrades that AOL makes available for Collaborative
                        Development Activities pursuant to this Agreement. Such
                        license shall be subject to the limitations set forth in
                        this Agreement on Sun's marketing and licensing thereof
                        during the term of this Agreement, which shall include
                        those limitations set forth in Sections 6.3, 6.6 and 6.7
                        of this Agreement as well as limitations during and
                        after the term of this Agreement permitting Sun and Sun
                        International B.V. to use the Existing Netscape Software
                        (and any Existing Netscape Software Upgrades, if any,
                        licensed to Sun) solely for purpose of developing the
                        New Browser, the OEM Communicator Client, and the
                        Designated Collaborative Software as part of the
                        Collaborative Development Activity. Such licenses shall
                        also be subject to any contractual restrictions with
                        third parties for the duration of such contractual
                        restrictions. AOL represents that concurrently with the
                        execution of this Agreement, AOL is obtaining from
                        Netscape contractual commitments requiring that Netscape
                        cooperate with AOL between the date of this Agreement
                        and the Closing Date to identify any "Encumbrances" (as
                        defined in this Section) that may adversely affect AOL's
                        rights to Netscape Existing Software and/or any
                        components thereof as set forth below, including without
                        limitation AOL's rights to grant others access to source

                        include granting AOL full access to Netscape technology
                        licenses, agreements by which technology rights were
                        acquired by Netscape and information regarding
                        intellectual property infringement or misappropriation

                        Software and all components thereof. As used in this
                        Section, "Encumbrances" means any restriction or limit
                        that would prevent or materially limit or restrict AOL
                        from granting pursuant to this Agreement the applicable
                        source and binary access, use and distribution rights
                        under Sections 9.6.1, 9.6.2 and 14.7 of the Agreement
                        with respect to the Netscape Existing Software or any
                        component thereof ("Sun License Rights"), including,
                        without limitation, limitations and restrictions on
                        source access and sublicensing fights, as well as
                        prohibitions or requirements to obtain consents to
                        assignment of rights from Netscape to AOL upon the
                        Closing Date where to failure to obtain such consent
                        would materially limit or restrict AOL's rights,
                        including sublicensing rights. AOL further represents
                        that it is obtaining from Netscape concurrently with the
                        execution of this Agreement contractual commitments

                        customary limitations and disclaimers of warranties and

                        granted to Sun pursuant to this Section 9.6.2 with
                        respect to the Existing Netscape Software shall

        APPROXIMATELY 5 LINES OMITTED *** Sun shall always position the
        Netcenter in its meetings, promotions and advertising no less favorably

        objectives of this Agreement require that Sun market and distribute the

        vendors without restriction, and in such cases such other connectivity
        and portal vendors shall have the right to use and promote their own

11.0    SYSTEMS PLATFORM.

        11.1 OWNERSHIP. Sun owns and controls the Sun System Platform without

        requirements.

12.0    BRANDING.

        12.1 OWNERSHIP. Each party shall retain all rights, title and other

        Third-Party Communicator Client meets the requirements for branding with
        such mark(s); (b) the right to use the Netscape trademarks that Netscape
        currently uses as the titles for the Existing Netscape Software in
        connection with the collaborative marketing and sales of the Existing
        Netscape Clients pursuant to this Agreement; and (c) such other
        trademarks, if any, as AOL and Sun may mutually agree. Such trademarks
        shall be licensed to Sun following expiration or termination of this
        Agreement subject to reasonable quality control requirements and a
        reasonable transition period (not to exceed fifteen (15) months) and

        meeting AOL's reasonable quality control and other transition
        requirements for such branding and subject to a phase-out of Sun's use
        of such trademarks in connection with such products after a reasonable
        transition period (not to exceed fifteen (15) months).

        12.3 BRANDING OF COLLABORATIVE SOFTWARE. The branding for the
        Collaborative Software shall be determined by mutual agreement of the

        each party shall have the right to use such marks in connection with the
        Product Suites and related sales and marketing materials during the term
        of this Agreement. Following any expiration or termination of this

        agreement. Following any expiration or termination of the Agreement, Sun
        and AOL shall each have the non-exclusive right to use any titles by
        which the individual Network Application and Server Products in the
        Product Suites were identified during the term of this Agreement,
        provided that AOL and Sun shall differentiate their uses of such marks
        following any expiration or termination of this Agreement by always
        using any such mark in connection with a name or trademark prominently
        identifying AOL or Sun as the source of such goods or services (for

        engaged full-time in the Collaborative Development Activity or in

        expenses in connection with its respective Incentive Plans. Compensation

        Marketing and Sales Plan. The parties commit to cooperate with one

        significant portion of their compensation through an incentive bonus
        program tied to meeting objectives under the Marketing and Sales Plans.

        Executive from each party, respectively, may make periodic project and

        14.1 TERM. This Agreement shall terminate at midnight Pacific Daylight
        Time on the date three (3) years following the Closing Date.

        effect as this Agreement using solely Sun technology, provided that if
        the parties fail to agree on such alternative terms within such thirty
        (30) day period, either party may elect to terminate this Agreement by
        giving written notice to the other party.

        14.3 TERMINATION FOR BREACH. Subject to Section 7.2 of this Agreement,
        either party may terminate this Agreement for a material breach of its
        terms by the other party by giving the other party written notice at
        least ninety (90) days in advance of such termination date, and the
        Agreement shall terminate on that date unless the breaching party has
        cured or corrected such breach prior to that time, provided that such
        ninety (90) day period shall be shortened to a ten (10) business day
        cure period following written notice in the event of a failure to pay
        amounts due pursuant to this Agreement. Without limiting the foregoing,
        in the event Sun fails to pay any amounts due to AOL pursuant to this
        Agreement, including without limitation minimum fees or revenues
        provided for in Sections 4.1.5, 4.5 and 9.8.2, and fails to cure such
        breach within the ten (10) business day cure period provided for in this
        Section, AOL shall have the right, exercisable upon written notice to
        Sun, without limiting any of AOL's other rights or remedies, to
        terminate this Agreement and all licenses granted to Sun by AOL,
        including all licenses granted to Sun by AOL pursuant to Sections 9.3,
        9.6 and 12 (in which event Sun will have no license rights pursuant to
        Section 14.7.1 or 14.7.2). In the event of a termination of this
        Agreement and all licenses granted to Sun by AOL as a result of Sun's
        failure to pay any minimum fees and revenues in a timely manner, Sun's
        obligation to pay all minimum fees and revenues provided for in Sections
        4.1.5, 4.5 and 9.8.2 shall be accelerated so as to make all such fees
        and revenues be due and payable immediately. Notwithstanding anything to
        the contrary set forth in this Agreement, AOL shall have no right to
        terminate the licenses granted to Sun by AOL pursuant to Sections 9.3,
        9.6 and 12, except for a failure by Sun to pay any fees and revenues due
        pursuant to this Agreement and a failure to cure such breach in a timely
        manner as provided in this Section 14.3.

        14.4 LIMITATION ON AOL RIGHT TO TERMINATE LICENSES. Except in the event
        Sun fails to pay the fees payable under Sections 4.1.5, 4.5 and 9.8.2 as
        required in Section 8 (the "Specified Payment Obligations"), AOL shall
        have no right whatsoever to terminate or reduce Sun's license rights set
        forth in Sections 9.4, 9.6.1, 9.6.2, 12.2, 12.3, 14.7.1 or 14.7.2 (the
        "Licenses") on the basis of any alleged breach by Sun of any of its
        obligations pursuant to this Agreement or for any other reasons, except
        to the extent permitted pursuant to a final, non-appealable judgment
        obtained from a court of competent jurisdiction in litigation between
        AOL and Sun. Notwithstanding anything to the contrary set forth in this
        Agreement, in the event AOL believes that Sun has breached any
        obligations under this Agreement, other than the Specified Payment
        Obligations, AOL shall have no right to terminate or reduce such
        licenses, even if AOL has terminated or purported to terminate this
        Agreement, and AOL's sole and exclusive remedy shall be to litigate the
        dispute, provided that nothing contained herein shall be deemed to limit

        minimum payments and fees that would have been due if this Agreement had

        "Bankruptcy Code"), licenses of rights to "intellectual property" as
        defined under Section 101(56) of the Bankruptcy Code. The parties agree
        that AOL and Sun, as licensees of such rights and licenses, shall retain

        analysis learned or developed by AOL in the course of its due diligence.
        Neither Sun nor AOL makes any representations or warranties to the other
        regarding Netscape or any aspect of its business, products, services or

        desire to conduct. Neither AOL nor Sun makes any representations or

        information provided by Netscape or the accuracy of any such
        information, materials, analysis or conclusions which AOL and Sun may
        have provided to the other party.

        requisite skills or experience, does not work well with other project
        team members, or is otherwise unsatisfactory, the parties will consult
