      infringement or other violation of any patent, copyright, trade secret,
      trademark or other proprietary rights of any other party.

12.5  Performance. Each Party represents and warrants to the other that their
      respective Intellectual Property when used in conjunction with the
      designated hardware will perform in all material respects according to any
      and all specifications, representations and functional specifications
      identified in the descriptions and technical specifications contained in
      the documentation related to each Party's Intellectual Property (as such
      documentation and specifications shall be amended from time to time).
      However, the Parties do not warrant that their respective Intellectual
      Property will be otherwise free of all errors or "bugs" as that term is
      commonly used in the trade. Each Party shall provide reasonable
      programming services to correct errors or "bugs" identified by the other
      Party, or shall, at its option, replace their respective Intellectual
      Property.

12.6  Year 2000. Each Party represents and warrants to the other that the
      occurrence in or use by their respective Intellectual Property of dates on
      or after January 1, 2000 ("Millennial Dates") will not adversely affect
      their performance with respect to date-dependent data, computations,
      output, or other functions (including, without limitation, calculating,
      comparing and sequencing) and that their respective Intellectual Property
      will create, store, process and output information related to or including
      Millennial Dates without errors or omissions and at no additional cost to
      the other Party. If requested by a Party, the other Party will provide
      sufficient evidence to demonstrate the adequate testing of their
      respective Intellectual Property to meet the foregoing requirements.

12.7  Ownership of Trademarks. As of the Effective Date, each Party represents
      and warrants to the other that (a) it is the sole owner of all right,
      title and interest in and to the Trademarks and (b) it has the absolute
      right to the use of the Trademarks and to grant the license granted in
      Section 4.6.

12.8  Limitation of Liability. EXCEPT WITH RESPECT TO EACH PARTY'S RESPECTIVE
      INDEMNIFICATION OBLIGATIONS UNDER ARTICLE 13, IN NO EVENT SHALL EITHER
      PARTY, ITS AFFILIATES, OR ANY OF ITS OR THEIR DIRECTORS, OFFICERS,
      EMPLOYEES OR AGENTS, BE RESPONSIBLE OR LIABLE FOR ANY INDIRECT,
      INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, PUNITIVE OR OTHER DAMAGES
      (INCLUDING, BUT NOT LIMITED TO, LOSS OF REVENUES OR LOSS OF PROFITS), EVEN
      IF THAT PARTY, ITS AFFILIATES, OR ANY OF ITS OR THEIR DIRECTORS, OFFICERS,
      EMPLOYEES OR AGENTS HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES,
      UNDER ANY CONTRACT, NEGLIGENCE, STRICT LIABILITY OR OTHER THEORY, ARISING
      OUT OF OR RELATING IN ANY WAY TO THIS AGREEMENT OR ITS IMPLEMENTATION.

13.   INDEMNIFICATION

13.1  Indemnification Obligation. Each Party (the "Indemnifying Party") shall
      defend, indemnify and hold harmless the other Party and each of its
      officers, directors, employees, agents and stockholders (the "Indemnified
      Parties"), from and against any and all claims, losses, liabilities,
      costs, settlements, damages or expenses of any kind (including reasonable
      attorneys' fees and disbursements) (collectively, "Indemnified Amounts")
      incurred by the Indemnified Parties which arise out of, relate to or are
      based upon (i) any claim that a Party's Intellectual Property infringes
      upon the intellectual property or other proprietary rights of a third
      party or (ii) any Party's negligence or breach of a representation or
      warranty or breach of a covenant obligation or agreement made by a Party
      under this Agreement, except to the extent such Indemnified Amounts are
      due to the gross negligence or willful misconduct of any Indemnified
      Party.

                                       11
<PAGE>

13.2  Indemnity Procedures. Each Indemnified Party agrees to give the
      Indemnifying Party prompt written notice of any matter upon which such
      Indemnified Party intends to base a claim for indemnification (an
      "Indemnity Claim") under this Article __. The Indemnifying Party shall
      have the right to participate jointly with the Indemnified Party in the
      Indemnified Party's defense, settlement or other disposition of any
      Indemnity Claim. With respect to any Indemnity Claim relating solely to
      the payment of money damages that could not result in the Indemnified
      Party's becoming subject to injunctive or other equitable relief or
      otherwise adversely affect the business of the Indemnified Party in any
      manner, the Indemnifying Party shall have the sole right to defend, settle
      or otherwise dispose of such Indemnity Claim, on such terms as the
      Indemnifying Party, in its sole discretion, shall deem appropriate,
      provided that the Indemnifying Party shall provide reasonable evidence of
      its ability to pay any damages claimed and with respect to any such
      settlement shall have obtained the written release of the Indemnified
      Party from the Indemnity Claim. The Indemnifying Party shall obtain the
      written consent of the Indemnified Party, which shall not be unreasonably
      withheld, prior to ceasing to defend, settling or otherwise disposing of
      any Indemnity Claim if as a result thereof the Indemnified Party would
      become subject to injunctive or other equitable relief or the business of
      the Indemnified Party would be adversely affected in any manner. The
      Indemnified Party may, at its sole cost and expense, participate in any
      such suit or action with counsel of its own choice.

14    DISPUTE RESOLUTION

14.1  The Parties agree that any breach of either of the Parties' obligations
      regarding trademarks, service marks or trade names and/or confidentiality
      would result in irreparable injury for which there is no adequate remedy
      at law. Therefore, in the event of any breach or threatened breach of a
      Party's obligations regarding trademarks, service marks or trade names
      and/or confidentiality, the aggrieved Party shall be entitled to seek
      equitable relief in addition to its other available legal remedies in a
      court of competent jurisdiction. For the purposes of this section only,
      the Parties consent to venue in either the state courts of the county in
      which Excite@Home has its principal place of business or the United States
      District Court for the Northern District of California.

14.2  In the event of disputes between the Parties arising from or concerning in
      any manner the subject matter of this Agreement, other than disputes
      arising from or concerning trademarks, service marks or trade names and/or
      confidentiality, the Parties shall first attempt to resolve the dispute(s)
      through good faith negotiation. In the event that the dispute(s) cannot be
      resolved through good faith negotiation, the Parties shall refer the
      dispute(s) to a mutually acceptable mediator for hearing in Redwood City,
      California if VStream initiates the dispute or Boulder, Colorado if
      Excite@Home initiates the dispute.

14.3  In the event that disputes between the Parties arising from or concerning
      in any manner the subject matter of this Agreement, other than disputes
      arising from or

                                       12
<PAGE>

      concerning trademarks, service marks or trade names and/or
      confidentiality, cannot be resolved through good faith negotiation and
      mediation, the Parties shall refer the dispute(s) to the American
      Arbitration Association for resolution through binding arbitration by a
      single arbitrator pursuant to the American Arbitration Association's rules
      applicable to commercial disputes. The arbitration shall be held Redwood
      City, California if VStream initiates the arbitration or Boulder, Colorado
      if Excite@Home initiates the arbitration, and the decision reached by such
      arbitrator shall be entered as a judgment in any court of competent
      jurisdiction.

15  EXCITE@HOME TO INVEST IN VSTREAM.

15.1  Excite@Home will invest in common stock of VStream as set out in Exhibit
      J.

16    GENERAL

16.1  Relationship of Parties. Nothing in this Agreement will be construed as
      creating any agency, partnership, or other form of joint enterprise
      between the Parties. Neither Party will have the authority to act or
      create any binding obligation on behalf of the other Party, and neither
      Party will represent to any third party that it has the authority to act
      or create any binding obligation on behalf of the other Party.


16.2  Notices. All notices, consents, waivers, and other communications intended
      to have legal effect under this Agreement must be in writing, must be
      delivered to the other Party at the address set forth at the top of this
      Agreement by personal delivery, certified mail (postage pre-paid), or a
      nationally recognized overnight courier, and will be effective upon
      receipt (or when delivery is refused). Any such notices sent to VStream
      must be addressed to the attention of its General Counsel. Each Party may
      change its address for receipt of notices by giving notice of the new
      address to the other Party.

16.3  Governing Law. This Agreement will be governed by and interpreted in
      accordance with the laws of the State of California as such laws apply to
      contracts made between California residents to be performed entirely
      within California. The United Nations Convention for the Sale of
      International Goods will not apply to this Agreement.

16.4  Waiver. The failure of either Party to require performance by the other
      Party of any provision of this Agreement will not affect the full right to
      require such performance at any time thereafter; nor will the waiver by
      either Party of a breach of any provision of this Agreement be taken or
      held to be a waiver of the provision itself.

16.5  Severability. If any provision of this Agreement is unenforceable or
      invalid under any applicable law or is so held by applicable court
      decision, such unenforceability or invalidity will not render this
      Agreement unenforceable or


                                       13
<PAGE>

      invalid as a whole, and such provision will be changed and interpreted so
      as to best accomplish the objectives of such unenforceable or invalid
      provision within the limits of applicable law or applicable court
      decisions.

16.6  Assignment. Neither this Agreement nor any rights or obligations of either
      Party under this Agreement may be assigned in whole or in part without the
      prior written consent of the other Party except in connection with a
      merger or sale of all or substantially all of the business or assets of
      the assigning party. Any attempted assignment in violation of the
      preceding sentence will be void. This Agreement will bind and inure to the
      benefit of the respective successors and permitted assigns of the Parties.
      NOTWITHSTANDING THE FOREGOING, in the event that the work.com organization
      within Excite@Home becomes a separate entity from Excite@Home, the Parties
      agree that the terms of this Agreement as they relate to the provision and
      use of the Premium Services shall apply to both work.com and to
      Excite@Home. Further, in the event of such a split between Excite@Home and
      work.com, the fees set out in Exhibit E which are identified for work.com
      service and or placements, shall be paid to work.com and fees incurred by
      either Excite@Home or Work.com in relation to the Premium Service shall be
      paid to VStream by the entity incurring the fee; provided, however, that
      VStream and work.com must enter into an agreement mutually satisfactory to
      the parties setting forth the performance terms and financial arrangements
      between VStream and work.com and that this Agreement be amended in a
      manner reasonably satisfactory to the Parties.

16.7  Force Majeure. Neither Party shall be liable for failure to perform or
      delay in performing any obligation under this Agreement if such failure or
      delay is due to any event directly impacting such Party's delay or failure
      to perform and beyond such Party's reasonable control, including fire,
      flood, earthquake, strike, war (declared or undeclared), embargo,
      blockade, legal prohibition, governmental action, riot, insurrection,
      damage, destruction, failures or delays in transportation or
      communication, failure or substitutions of equipment, labor disputes,
      accidents, shortages of labor, fuel, raw materials or equipment or
      technical failures or any other similar cause; provided that the Party
      claiming such force majeure event makes reasonable efforts to exercise
      such control. The Party affected by such event of force majeure shall not
      later than seven (7) days after the commencement of such event give notice
      to the other Party of such event and shall use its best efforts to resume
      full performance of its obligations under this Agreement as soon as
      commercially possible.

16.8  Construction. The section headings appearing in this Agreement are
      inserted only as a matter of convenience and in no way define, limit,
      construe, or describe the scope or extent of such section or in any way
      affect this Agreement. Unless otherwise expressly stated, when used in
      this Agreement the word "including" means "including but not limited to."

16.9   Entire Agreement and Amendment. This Agreement together with its Exhibits
       completely and exclusively states the agreement of the Parties regarding
       its subject matter. It supersedes, and its terms govern, all prior
       understandings, agreements, or other communications between the Parties,
       oral or written, regarding such subject matter. This Agreement may be
       executed in counterparts and may be amended only in a document signed by
       both Parties.

16.10  Counterparts. This Agreement may be executed in counterparts, each of
       which shall be deemed an original, but all of which together shall

                                   ---------

                         DESCRIPTION OF BEEP SERVICES

VStream provides an Internet Communications service called, Beep which provides
the services described in the Beep Technical Manual published by VStream 1999
and all updates and additions to that Manual during the Term

Beep is a service allowing end-users to author voice messages over their
telephone for streamed playback over the Internet and distributed through a link
in an e-mail or embedded in an application such as a message board posting or
added to a web page.

The Beep service, is available from VStream's website at http://www.vstream.com.
Messages may be up to two (2) minutes in length and will be stored for thirty
(30) days, unless otherwise mutually agreed upon.







                                                                               1

                                   ---------

      ENGINEERING SERVICES PROVIDED TO EXCITE@HOME

1.  Description of Work to Be Done by VStream

    a)   VStream and Excite@Home will work together to integrate the Beep
         service into the Excite@Home products listed in Exhibit C.

    b)   Beeps are categorized on input by the portal from which they originate.
         In these cases, Excite@Home will be the originating site. Because of
         the volume of Beeps that will be performed through the period of the
         contract, VStream will construct a separate database infrastructure to
         support this traffic.

2.  When is complete work to be delivered/Milestones

    Beep will be integrated on the Excite Network as per the following
    timetable:

       VStream service delivery plans:

            On or before December 15, 1999: VStream will deliver the ability to
            perform two hundred and fifty thousand (250,000) beeps per day.

            On or before March 15, 2000: VStream will deliver the ability to
            perform one million (1,000,000) beeps per day.

            If the number of Beeps exceed the performance numbers listed above
            the system will fail over to a temporary "service busy" type of
            message (exact text to be determined) until such time that the peak
            load falls under the numbers listed above.

All of the above integration timetables assume that Microsoft delivered to
VStream the source code for Window's Media Player on or before November 17,
1999.  In the event that Microsoft does not deliver to VStream the source code
for Window's Media Player on or before November 17, 1999, then VStream's
integration obligations with respect to Beep, as set forth in the Agreement,
will be extended one day for each day that Microsoft delays in delivering the
source code for Window's Media Player to VStream.

3.   Technical Specifications The following is a summary of how Beep integration
     will work. The specific integration process may vary depending upon the
     needs of the specific products involved.

     The Co-Branded Pages or product integration external site, at some point in
     it's flow, needs to send a URL to VStream to indicate that a voice message
     is to be created (this will be called the Beep Request below). This message
     can take the following parameters:

A unique ID to be associated with this voice mail request. If the external site
is sending out its own message or web page to the end user, then they should
pass us this unique ID so that they can include it in their page/email to later
request the voice message (e.g. they might embed an image in their page that
when clicked will make a URL request from VStream to play the voice message.
This request would require passing the unique ID.). However, if the external
site is going to rely on VStream to send an email containing the voice message
link, then this parameter can be left off, and we will create a unique ID on our
own.

The URL of a page that will display the phone # and message ID to use to record
the Beep (called the Dial Instructions page below). The Beep Request will
reserve a line and message ID and then redirect to Dial Instructions page,
passing the phone # and message ID as parameters. The Dial Instructions page
should display these values along with instructions on how to make the call. It
can reside at VStream or on the external site.

           i)   (optional) The email address of the sender, and a comma
                separated list of recipient email addresses. This information is
                required if VStream will be sending the emails with the voice
                message links, but not if the external site is sending these.

          ii)   (optional) A parameter indicating whether the sender should get
                notified when their Beeps are played.

   a)   The sender then needs to make the phone call and leave their message.

   b)   If VStream is sending emails, when the call is complete, VStream will
        send an email with a link to play the voice message to the sender and
        the recipients.


                                                                               4
<PAGE>

c)  There are many options for how the recipients access the voice message. If
    VStream sends an email, then the email simply has a link to play the stream.
    Clicking this link will bring up a page that is on VStream's site. This page
    checks if the Beep is still active, and if so calls up the appropriate media
    player and plays the message.

d)  If the external site is sending an email, then their email will typically
    contain a link to some page they are presenting to the user. This page
    should contain some mechanism for checking with VStream to see if the voice
    message was recorded, and if so to play the stream. This can be done in
    several ways such as:

        i)    The external page could contain an image that says something to
              the effect of "Click here to listen to your voice message". This
              image would be located on VStream's site. When this image is
              requested from the external site's page, VStream checks its
              database and determines if the sender ever successfully completed
              the phone call. If so, then VStream passes back the real image,
              otherwise we pass back a one pixel transparent gif, so the user's
              page effectively does not have the "play the message" image.

        ii)   Or the external page could be a page that calls a VStream URL and
              the VStream URL checks the status of the voice message and then
              redirects to a page on the external site passing the status as a
              parameter. This secondary external site page would then take the
              status as input and put up a different page depending on whether
              the Beep had been recorded or not.

        iii)  Or the external page could have an embedded call to VStream that
              requests the status (e.g. doesn't exist, available expired) of the
              specific recording clip and then uses this status to render a
              specific user experience for the End User.

                         EXCITE@HOME INTEGRATION PLANS

Excite@Home shall integrate VStream's Beep services into the following products:

1.  Excite Mail

    a)  The Beep product will be integrated into the Excite Mail and Excite
        Voicemail in the "Compose" page of Excite Mail. Subject to UI design, it
        is envisioned that the user will be able to send a Beep message by
        checking on that option within the Compose Message screen. User will see
        another page, where VStream will provide the Excite user with a unique
        ID (and telephone number) associated with the request so that the
        voicemail message can be recorded. This page will be a Co-Branded Page.

    b)  The notification option ("your email & voicemail (Beep) message was
        read") to the Excite user can also be integrated into the product.
        Subject to UI design, the additional option can be added on the page
        where the unique ID & telephone number information is presented. This is
        currently accomplished via an email notification mechanism. This can be
        turned off at Excite@Home's discretion.

2.  Excite Clubs

    a)  There are many areas within the Excite Club's product in which we can
        integrate Beep. Beep could be integrated into the invitation service,
        into individual Excite Club's applications as an additional way for end
        users to leave announcements, discussions, messages or comments. Beep
        could also be integrated with the textual description on the welcome
        page and uploaded files.

    b)  We intend to integrate Beep into Excite Clubs in stages. The first stage
        will be attaching a Beep to an email in the invitation service. The
        second stage will be adding Beeps to the threaded discussion comment
        boxes. From the user reaction, we will see if adding Beeps into
        descriptions or other places is warranted.

    c)  Specific integration points include:

        i)   Invitations to join a club.

          .  The invite service sends email messages to prospective club
             members. A beep could be attached to these emails. The compose page
             for the email will contain the telephone number and unique ID
             number to add a voice message. The instructions on how to add the
             message will also be on this page.


                                                                               6
<PAGE>

            .  The recipient will receive an email that will contain a link to a
               community page. This page should have a way to check with VStream
               to see if the voice message was recorded, and if so to play the
               message.

            .  This work will take six weeks of development and QA time. It is
               scheduled to start in mid-January, 2000.

        ii)    Leaving a voice comment

               Announcements, Discussions, Calendar, Links, Contact list, Photos
               and Files all have comment boxes. A user would have the
               opportunity to leave a voice comment in addition to a textual
               comment. The instructions, telephone number and unique ID would
               either be on the same page as the comments box, or on a separate
               page linked from that discussion page.

            .  Once recorded, the message will appear as a link within the
               threaded discussion. Users will listen to the message by clicking
               the link causing the message to play if recorded.

            .  This work is expected to take twelve (12) weeks of development
               and QA time. It is scheduled to begin at the end of February.

        iii)   Descriptions with text and voice

            .  The welcome page, links and uploaded files and photos, contacts
               and calendar events have a textual description. These
               descriptions could be enhanced with a Beep. We will look into
               this implementation once we receive feedback from using Beep in
               these other areas.

3.  Excite Personals

    a)  Excite Personals has two areas of Beep integration:

        i)     Place Personal Ads

            .  Users will be able to include a voice message along with their
               other static text information to appear in their personal ad
               (HTML page). This integration of Beep would occur in the `place
               ad' and `detail page rendering' processes.

        ii)    Respond to Personal Ads

            .  Users that respond to personal ads can attach a voice message
               along with their email response. This integration would occur in
               the `send email message' process.


                                                                               7
<PAGE>

4.  Excite Member Directory

    a)  Integration into the Excite Member Directory pages such that users can
        record voice messages for playback as part of their personal profile.
        The integration process and plans will be similar to other integration
        efforts as described above.


                                                                               8

                            MAINTENANCE AND SUPPORT

VStream shall provide the following support, maintenance, performance and uptime
guarantees to Excite@Home for the BEEP and the Premium Services:

1.  Maintenance

    a)  VStream shall provide during 6:00AM-6:00PM Pacific Time on VStream's
        normal business days, telephone consulting services to Excite@Home's
        designated personnel to assist such personnel in resolving problems,
        obtaining clarification relative to Beep and Premium Services and
        providing assistance regarding suspected defects or errors in Beep and
        Premium Services.

    b)  VStream will also provide email development support to Excite@Home.
        Excite@Home's use of such support shall be restricted to calls related
        to Severity 1 and Severity 2 issues as those terms are defined in
        Exhibit D. VStream will make all reasonable efforts to respond to
        Excite@Home's "after hours" support requests within the standards set
        out in Exhibit D prior to the next business day following receipt of the
        request.

    c)  By mutual agreement of the parties, VStream shall furnish qualified
        personnel for on site assistance to Excite@Home to resolve problems and
        to assist in customization.

    d)  VStream agrees to diligently work for the prompt resolution of defects
        and errors in Beep and Premium Services. VStream agrees to respond to
        Excite@Home by using a dedicated contact telephone number for each
        support call.

    e)  Notwithstanding the forgoing, in the case of a system down condition,
        (i.e. Severity 1, as defined below) attributable to VStream, VStream may
        utilize other means of communication for both reporting of errors and
        the conditions thereof.

    f)  VStream shall respond to and complete correction of errors, defects and
        malfunctions, in accordance with the following schedule:

      Severity 1   Causes data corruption or system crash or Excite@Home cannot
                   make effective use of Beep and/or Premium Services;
      Severity 2   Feature does not work as documented, no reasonable work
                   around exists and Excite@Home has a critical need of the
                   feature;


                                                                               9
<PAGE>

      Severity 3  Feature doesn't work as documented but a reasonable work
                  around exist or Excite@Home can wait for the next release for
                  a fix;
      Severity 4  Enhancement request.

    g)  VStream shall make an initial response to a Severity 1 normal

        be responded to on a 24 hour by 7 day a week basis. VStream shall use
        best efforts to provide a fix, work around, or to patch Severity 1 bugs
        within twenty four (24) hours after the bug is replicated by VStream and
        confirmed as a bug by VStream.

    h)  Provided that maintenance calls are received within VStream's normal
        maintenance hours, VStream shall make an initial response to Severity 2
        maintenance calls within four hours after receipt. VStream shall make
        commercially reasonable efforts to provide a fix or work around for
        Severity 2 bugs within five business days.

    i)  Provided that maintenance calls are received within VStream's
        maintenance hours. VStream shall make an initial response to Severity 3
        maintenance calls within twenty-four (24) hours after receipt. VStream
        shall make reasonable efforts to identify a resolution to Severity 3
        bugs within thirty (30) days and to incorporate Severity 3 fixes in the

    j)  Provided that all maintenance calls are received within VStream's
        business hours, VStream shall make an initial response to Severity 4
        maintenance call within forty-eight (48) hours after receipt. Severity 4
        issues will be dealt with on a case-by-case basis and no blanket
        commitments will be made.

    k)  Excite@Home shall appoint one person as the principle point of contact
        for the communication of bugs and errors to VStream and for the receipt
        of bug and error fixes, work around and updates, if any. Additionally
        Excite@Home may appoint another person as a back up of the principle
        contact.

2.  Uptime Guarantee

    a)  The portions of Beep and or Premium Services which are operated by
        VStream shall have at least the following uptime as measured monthly
        excluding planned downtime: for the first six months of commercial
        availability of Beep and Premium Services, 98.8%, with a goal of 99.8%;
        for months 7-12, 99.4% with a goal of 99.8%, and for months thirteen and
        after during the term of the Agreement, 99.8%. In addition, the portion
        of Beep and Premium Services operated by VStream will not experience
        more than two outages (unscheduled downtime) of more than two hours in


                                                                              10
<PAGE>

         any month. The GUI hosted by Excite@Home shall meet this standard and
         the VUI and other components hosted by VStream shall meet this
         standard.

    b)   VStream will notify Excite@Home within fifteen (15) minutes of any
         known and verified unscheduled downtime of the Services and update the
         status to Excite@Home each and every hour until the service is back up.
         VStream will immediately notify Excite@Home when the service is
         restored. Excite@Home will notify VStream within (15) minutes of any
         known and verified unscheduled downtime of the Services and update the
         status to VStream every hour until the service is back up.

    c)   Scheduled downtime shall be no greater than four hours bi-weekly and
         shall happen at a regularly scheduled time during off-peak periods. The
         current plan is for scheduled downtime to occur every two weeks between
         10PM and 2AM Pacific Time on Saturday evenings. Actual scheduled
         downtime for the VUI components of the Excite@Home UM service will
         normally not exceed fifteen (15) minutes. A mechanism will be put in
         place by which users are notified of scheduled down time expected to be
         over one hour at least seventy-two (72) hours before downtime occurs.

    d)   Components of the system, where technically feasible, shall be
         redundant and fault tolerant for both Excite@Home and VStream's
         operations.

3.  System Performance

    a)   Latency of any data from the time VStream's server receives the request
         to serve such data to the time when VStream's server begins to serve
         such data shall be less than or equal to three seconds, outside of the
         PIN number example given in Exhibit D, Section 3b, the next section.

    b)   Latency of PIN numbers during registration being served from VStream to
         Excite@Home or Excite@Home to VStream shall be no greater than four
         seconds (e.g. PIN numbers during registration.), in at least 90% of
         cases, and in no case shall PIN presentment be in excess of 10 seconds,
         independent of network or Internet conditions.

    c)   Throughput of all data being served directly to the end user shall be
         sustained at least 50Kbits/sec as measured by Excite@Home's monitoring
         stations, in at least 80% of monitoring cases, and assuming such
         monitoring stations can receive sustained data rates in excess of
         50Kbits/sec from most other locations on the Excite@Home site.

4.  Performance Measurement

     VStream will provide outage reports to Excite@Home when necessary.


                                                                              11

                                   ---------

                                FINANCIAL TERMS

VStream shall make payments to Excite@Home under the following terms:

During the Term of this Agreement, VStream will pay Excite@Home [...**...]% of
gross receipts (less cost of long distance services, taxes and credits) from End
Users of the Premium Services originating from Work.com site.  Such payment will
be credited towards the then current quarterly payment for slotting fees and
startup costs set out in Exhibit E (no quarter to quarter carry forward is
allowed). VStream shall be allowed to suspend payment of the slotting fees set
forth in this Exhibit E after the end of any quarter for the Term of this
Agreement if (i) the VStream services have been completely integrated into
Work.com (except where such integration has not occurred due to VStream default)
or (ii) VStream has not sold Premium Service to customers who purchased and used
the Premium Services through work.com as follows:

At least [..**..] customers by March 31, 2000; and

At least [..**..] customers in each subsequent quarter during Term of the
Agreement thereafter.

Notwithstanding the foregoing, if VStream's obligation to make scheduled
payments is suspended, the obligation will resume once the conditions set forth
in the preceding sentence are satisfied and VStream agrees that it shall resume
payments of the slotting fees at the point of suspension  and Excite@Home has
the option to extend the Term of the Agreement for same period of any suspension
to assure Excite@Home that the full value of the slotting fees shall be paid by
VStream. Notwithstanding the foregoing, Excite@Home's right to extend the
Agreement pursuant to this section shall not exceed seven additional quarters.

During any extension, all other terms relating to Work.com will still apply.
The only difference is that payments are then due in arrears instead of in
advance, and any missed quotas during the extension period(s) do not translate
to additional extensions.

In the event audio advertising is sold within the service offering, Work.com
will, at its option, be responsible for selling such advertising and will share
[...**...]% of the Net Advertising  Revenue with VStream. Work.com may choose,
however, to allow VStream to sell some or all of the advertisements. The selling
party will be compensated for sales commissions up to [...**...]%.  The serving
party will be compensated for reasonable serving and tracking costs.

In the event that the Premium Services are incorporated on the Excite@Home
Network outside of the Work.com site, Excite@Home shall, at its option, be
responsible for selling advertising and will share [...**...]% of the Net
Advertising Revenue with VStream. Excite@Home may choose, however, to allow
VStream to sell some or all of the advertisements.

                              SALES AND MARKETING

1.  Excite@Home Communities Placements

    a)   Excite@Home will provide VStream with the following advertising and
         promotional placements:

    b)   Voice Chat Module: Today, our Voice Chat audience is largely made up of
         18-30 year olds. VStream can target their age demographic, which will
         attract college students, and young adults (age 21-33 is 33% of Voice
         Chat traffic). The placement is a graphic module 100x30 2k in size, and
         two lines of text, one line an active link.

    c)   Directory Pages Module: Upon entering Excite People and Chat, users
         drill down by category prior to entering a community, chat room, or
         message boards. VStream can target all desirable categories, i.e.
         Business, Shopping, Auto's etc. The placement is a graphic module
         100x30 2k in size, and two lines of text, one line an active link --
         right hand navigation.

    d)   Excite Voicemail: Excite Voicemail, offers users the ability to receive
         Voicemail and faxes, in their Excite Mail Inbox. Excite Voicemail is
         the only service available nation wide, and available toll free nation
         wide. Messages are left via 800#ers, users have personal pins, messages
         are retrieved via Excite Mail Inbox in the form of audio files.
         VStream's demographic highlight for Excite Voicemail will be the early
         adopters age 21-33 is 33% of the prospective traffic. The placement is
         a graphic module 100x30 2k in size, and two lines of text, one line an
         active link.

    e)   Excite Mail: Excite Mail is experiencing an average of 5M page views
         per day and growing rapidly. Excite Mail recently recorded more than
         one million members using their Mail account at least once during the
         week (Forrester Research). The placement is a graphic module 100x30 2k
         in size, and two lines of text, one line an active link.

2.  Excite@Home Personals Placements

    a)   The homepage of Personals will promote VStream by including a text link
         calling out the Beep functionality in the `Resources' area. This link
         from the homepage will lead to a splashpage that provides a description
         of Beep and how it works within Personals in more detail. This page
         could feature VStream's other products and include a "More about
         VStream" link or other link to be mutually agreed on. This link could
         take users to the Work.com Premium Services or Excite Premium Services
         areas.

                                                                              16
<PAGE>

    b)   Branding of VStream (or Beep depending on preference) through inclusion
         of a static (non-linked) logo at every product integration point (on
         place ad pages and send message pages) or as a hyperlink to a co-
         branded page agreed upon by both parties.

                                                                              17

                                 USAGE REPORTS

All usage reports shall be delivered on a weekly basis by email or in other

                              LINKS AND OWNERSHIP



The Agreement has a large number of interaction points where data and
advertising opportunities are created. One or more of the parties may own
advertising registrations and other data resulting from this Agreement.
Furthermore, the relationship of what VStream advertising points to where is
complex and intertwined with the data question above. The picture below creates
a basis from which we can understand where data is created and where the
ownership of that data lies.



                           [FLOW CHART APPEARS HERE]


1.  Advertising

    a)   Let's begin by looking at VStream advertising. This advertising comes
         from a variety of sources and has restrictions on where they can direct
         traffic. These include:

          Ad buy mandated by the Excite.com term sheet can point to:Excite.com
          VStream co-branded site/services, Work.com co-branded site/services,
          or the VStream site.
          Ad buy mandated by the Work.com term sheet can only point to the
          Work.com co-branded site/services.
          3rd party ad buy that VStream makes on its own can point anywhere.
          Ad inventory created as a result of the fulfillment of the VStream
          service (such as inventory/hyperlinks in confirmation emails,
          notification emails, etc.)

                                                                              24
<PAGE>

               From Excite.com generated users can point to Excite.com VStream
               integrated services or Work.com co-branded site/services.
               From Work.com generated users can only point to the Work.com co-
               branded site/services.
               From VStream generated users can point anywhere.
               This inventory can also be sold to third parties, at the approval
               of both Excite@Home and VStream, under the terms defined above.

    b)   Product Level Integration such as the VStream logo or name
         (hyperlinked) within the co-branded property can only point to co-
         branded content.

2.  User Data Ownership and Rights

    a)   If the user was generated from an integrated service on Excite.com or
         Work.com then that user is tied to that origin and henceforth
         considered an Excite.com or Work.com customer (as appropriate). (A user
         being defined as a customer who has used one of the integrated Premium
         Services or registered within one of the Premium Services/sites.) If
         that user was generated from the VStream.com site, that user is a
         VStream user.

    b)   At the termination of the Agreement between Excite@Home and VStream,
         Excite@Home retains the rights to the User Data as defined in the
         Agreement for the period of six (6) months from the date of
         termination. After this period, each party has independent right to the
         User Data.

    c)   The origin of the user must be maintained with the user records for
         that user along with the origination date. Once identified, a user is
         always tied to that origination source. VStream will make monthly dumps
         to Excite.com and Work.com originated user data to Excite@Home in a
         mutually agreed to format.

    d)   Excite.com retains the right for users originating at Excite.com to:

         Approve all correspondence and marketing messages to users (VStream may
         cross-promote other co-branded services at the approval of
         Excite.com).-Best effort will be made to give content approval within
         one business day, with a maximum of three business days taken.

               Market directly to those users if they are `opt-in' users of the
               Premium Services.
               Market to those users integrally as part of the Premium Service
               (in confirmation emails, etc.).
               Choose the tools for delivering notification/confirmation emails
               (e.g. VStream or DeliverE).

                                                                              25
<PAGE>

    e)   VStream will make an attempt to Opt-in each user it acquires for itself
         or on behalf of Excite.com or Work.com. If a user is not opted-in, no
         correspondence, marketing, etc. will be delivered to that user other
         than that which is standard for the service (such as notify and
         confirmation emails.) Every registration/data entry page must present
         an opt-in opportunity. An opt-in MUST be presented at every opportunity
         that a user enters personal information.

                                                                              26

                   Terms for Integration of Premium Services

                                within Work.com
                                ---------------

1.  Premium Services Definition

         Premium Services shall mean the VStream NetCall Service which is
         described in the NetCall Technical Manual published by VStream 1999 and
         any additions to such Manual, and that includes all of the following
         Audio Conferencing and Web Collaboration component services:

    a)   Audio Conferencing: any "real-time" two-way use of audio over the PSTN
         (Public Switched Telephone Network) capable of three or more
         participants.

    b)   Web Collaboration: the ability of two or more people or groups to
         exchange and manipulate data and information over the Internet in
         "real-time". All of the following services (C-I) are collectively
         referred to as Web Collaboration Services.

    c)   Streaming: the delivery of live or archived media files over the
         Internet upon user request wherein the playing of the media file begins
         without the file being completely downloaded.

    d)   Full Text Chat: The ability for a user to send text messages to another
         individual user or to multiple users in "real-time" over the Internet.

    e)   Application Sharing: The ability for a user to share any Windows
         Application with one or more participants over an Internet. Such
         sharing includes the ability to share or transfer control of the
         application to other participants, even though the actual document
         being manipulated (such as an Excel spreadsheet) and the software that
         controls the document (in the aforementioned example, Excel) are not
         resident on the participants' computers.

    f)   Web Touring: The ability to lead one or more participants through a
         controlled series of live Internet web pages.

    g)   Polling: the ability of a NetCall moderator to poll End Users within a
         given NetCall session

    h)   Voice over IP ("VoIP") conferencing: the ability for End Users within a
         NetCall session to chat with each other or the moderator using spoken
         voice instead of text.

    i)   Voting: similar to polling the ability for End Users within a given
         NetCall session to vote on issues presented to them by a NetCall
         moderator

                                                                              27

2.  Premium Services Pages

    a)   At Execution VStream will deliver web pages containing the complete
         content and functionality of the NetCall Service described in Section 1
         of this Exhibit ("Premium Services Pages") for display on the Work.com
         portion of the Excite@Home Network.

    b)   The Premium Services Pages will be in accordance with Guidelines that
         Excite@Home has provided VStream which include but are not limited to
         page performance standards, header and other design/user interface
         standards.

    c)   The Premium Services Pages will carry both Work.com branding (or other
         branding chosen by Excite@Home) and VStream branding, both visually and
         aurally, displayed in substantially equivalent location, size and
         prominence. All Excite@Home branding will be displayed as consistent
         with the rest of the Excite Network.

    d)   The "look and feel" of the Premium Services Pages will be consistent
         with the "look and feel" of the Excite Network. The final approval over
         the "look and feel" of the Premium Services Pages will be for
         Excite@Home.

    e)   VStream will host the Premium Services Pages but they will be served
         from a "Work.com" domain name (or such other domain(s) Excite@Home may
         determine in its sole discretion) so that Excite@Home can get reach and
         page view credit.

3.  Terms for Use of Premium Services on the Work.com

    a)   Subject to any agreements executed by Excite, Inc. or At Home
         Corporation for technology that is available for integration on the
         Excite@Home Network, and to the terms of this Agreement, VStream will
         be the sole provider of Premium Services within Work.com for the Term
         of the Agreement.

    b)   Notwithstanding section 3(a) of this Exhibit, Excite@Home may at any
         time integrate third party vendor technology to the Work.com site that
         includes various component features of the Premium Services but which
         does not include all or substantially all of the complete Premium
         Services functionality as a single integrated service similar to
         NetCall.

    c)   Subject to section 3(b), Excite@Home shall give VStream thirty(30)days
         written notice of its intent to integrate such features, which notice
         shall set forth all material terms of such integration.


                                                                              28
<PAGE>

    d)   Subject to section 3(b), VStream may agree to provide such features to
         Excite@Home as part of an enhanced NetCall offering (Premium Service)
         on the terms set forth in such notice where such VStream services are
         comparable to the Excite@Home proposed service in terms of
         functionality, performance, price and time to market, Excite@Home and
         VStream will enter into an agreement for the integration of such
         services. Nothing in this section shall prevent Excite from offering
         such component services as components on the Excite@Home Network.

    e)   The Premium Services Pages will be prominently featured within Work.com
         pursuant to the terms of this Agreement.

    f)   Subject to the terms of this Agreement, Premium Services will receive
         no less prominence than any other telephony service featured in
         Work.com (exclusive of ad buys).

    g)   VStream shall ensure that the Premium Services as an aggregate, and
         each component thereof are at all times "Best of Breed".

    h)   During the Term, and subject to VStream full compliance with Section
         3(e) above, the Work.com portion of the Excite@Home Network shall not
         promote any other aggregated Audio Conferencing and Web Collaboration
         services on the Work.com site. Notwithstanding the foregoing,
         Excite@Home may promote services as required by agreements executed
         prior to this Agreement, and Excite@Home may promote services which
         have features similar to individual component features of the Premium
         Services, but which do not contain the complete functionality of the
         Premium Services (e.g. Excite@Home may offer file upload services to
         Work.com users, and such file upload services could include streaming
         as a secondary product feature).

    i)   If at any time during the Term of this Agreement, VStream cannot offer
         Best of Breed quality for the Premium Services, or any component
         thereof, Excite@Home will notify VStream in writing of its intention to
         remove the non-Best of Breed component of the Premium Services from the
         Excite@Home Network. On VStream's receipt of any such Notice, VStream
         will be allowed two (2) weeks to propose a mutually acceptable remedy
         to re-establish the Premium Services and all components as Best of
         Breed. VStream agrees that any such plan must be fully implemented
         within thirty days of notice to from VStream. (VStream shall have 90
         days to remedy the default if the component is a new feature that was
         requested for inclusion by Excite; provided however such new feature
         must be in a format supported by VStream). If VStream is unable to
         submit an acceptable plan to Excite@Home or if VStream confirms that it
         cannot provide the requested expanded capabilities, Work.com shall be
         able to immediately replace that non-Best of Breed portion of the
         Premium Services with an alternate vendor.



                                                                              29
<PAGE>

    j)   The Premium Services shall at all times allow End Users to view MS
         PowerPoint files, JPEG's or GIF images, ask questions to the moderator
         via a modified chat capability, and view the names of other
         participants in the collaborative event.

    k)   In order for the Premium Services to retain their Best of Breed status,
         VStream will integrate, within six (6) months of the Work.com Launch
         Date, into the Premium Services a separate platform that will include
         the majority of the following features on a Best of Breed basis:

       .  Polling,
       .  Full Text Chat,
       .  Web Touring,
       .  Application Sharing
       .  VoIP Conferencing, and
       .  Voting.

      The minimum Web Collaboration functionality to be available to Excite@Home
      to provide End Users in a form that is fully functional and bug free in
      place by the end of January 2000 shall include Full Text Chat, Application
      Sharing And Web Touring Functionality ("Minimum Web Collaboration
      Functionality").

      Should VStream fail to deliver Minimum Web Collaboration Functionality by
      end of January 2000, then Excite@Home will not be obligated to feature any
      VStream Web Collaboration services and Excite@Home may develop alternate
      relationships with other vendors to provide similar services to End Users.

      All of the above integration timetables assume that Microsoft delivered to
      VStream the source code for Window's Media Player on or before November
      17, 1999. In the event that Microsoft does not deliver to VStream the
      source code for Window's Media Player on or before November 17, 1999, then
      VStream's integration obligations with respect to Beep, as set forth in
      the Agreement, will be extended one day for each day that Microsoft delays
      in delivering the source code for Window's Media Player to VStream.

      l)   VStream will provide best commercial (most favored nation) pricing to
           Excite@Home End Users of the Premium Services. No other portal
           partner (i.e. Yahoo!, Lycos, etc.) users of Premium Services shall
           receive more favorable end-user pricing than End Users -- whether
           through direct license from VStream, or through any other
           distribution points through which VStream provides Premium Services.

      m)   VStream cannot market any other services outside of this Agreement to
           End Users without prior written approval to Work.com users.

                                                                              30
<PAGE>

    n)   All materials presented to End Users by VStream, through any medium,
         will be co-branded Excite@Home (or any other proprietary brand of
         Excite@Home) and VStream with equal or greater prominence to
         Excite@Home.

    o)   VStream has the right to develop and enhance its Premium Services, and
         promote those enhancements to Work.com End Users, so long as those
         enhancements: a) reasonably fall within the services that Excite
         originally contracted with VStream to provide, and b) are a part of the
         Premium Services which Excite@Home may elect to provide on any portion
         of the Excite@Home Network. Excite@Home and VStream must mutually agree
         to any such promotion.

    p)   If Work.com chooses to offer any streaming services or video
         conferencing services to its user base, separate from the automated
         conferencing service provided by VStream, where such streaming services
         are not components of other product offerings, VStream has the right of
         first refusal to be the provider for those services.

                                                                              31

4.   Terms for Use of Premium Services on the Excite@Home Network

     To the extent Excite chooses to offer the Premium Services elsewhere on the
     Excite Network and separate from the Work.com URL the following additional
     terms shall apply.

a)   Excite@Home may integrate the Premium Services on the Excite@Home Network
     in areas outside of Work.com in its sole discretion provided that
     Excite@Home and VStream shall share revenue from the pages on the
     Excite@Home Network which incorporate Premium Services as set out in
     Exhibit E and Article 6 of the Agreement.

b)   There shall be no restrictions on Excite@Home's use or promotion of third
     party services not included in the Premium Services or component portions
     of the Premium Services (including without limitation any Audio
     Conferencing, Web Collaboration or streaming media services) on non-
     Work.com portions of the Excite@Home Network.

c)   If commercially reasonable, Excite@Home may, at its discretion, ask VStream
     to integrate the Premium Services Pages with Excite@Home's Universal
     Registration System. VStream will integrate according to Excite@Home's
     technical and operational specifications. Each party will pay their own
     costs related to the integration.

d)   At Excite's discretion all Work.com branding and URL's may be replaced with
     Excite branding and URLs.

e)   Linking to the Premium Services Pages from Excite URLs and products will be
     subject to the approval of VStream with such approval not to be
     unreasonably withheld. Notwithstanding the forgoing Excite may place links
     to the Premium Services Pages or integrate the Premium Services into the
     Co-Branded Pages at Excite's discretion.

f)   The use or promotion of the Premium Services on or from the Excite site,
     separate from the Work.com site, shall in no way increase any obligations
     to which the Work.com URL may be subject as per the terms of this
     Agreement.


                                                                              32
