                               Statement of Work

Party Responsibilities

1.  iBEAM will be responsible for the following actions:
    .  A satellite pre-installation site survey of the facility by phone or at
       iBEAM's and NorthPoint's option at customer site.

    .  The installation of the satellite dish utilizing a non-penetrating roof
       mount on the roof of the facility or a designated area of the building,
       depending on the availability of such space.

    .  The running of coaxial cable to the data or rack room where the iBEAM
       MaxCaster indoor components will be racked.

    .  The racking and cabling of the server and switch components of the
       MaxCaster.

    .  Registration and pointing of the satellite system.

    .  The activation of the system with the iBEAM Network operations monitoring
       facility. This includes adding IP Addresses, Host ID names to the iBEAM
       server and to Tier 1 NOC.

    .  Orientation of the customer technical staff to the equipment and to the
       remote monitoring process.

    .  Alert NorthPoint during power outage or any iBEAM Network outage, whether
       planned or otherwise, by telephoning NorthPoint at NorthPoint-specified
       numbers.

2.  The Member will be responsible for the following actions:

    .  Completion of the customer data network site survey. This information is
       critical to the iBEAM Tier 1 NOC in the monitoring of the MaxCaster and
       to the integration of the MaxCaster in the data network. The customer
       will be required to provide IP addresses, host ID names, subnet masks,
       and gateway default as specified by iBEAM.

    .  Designate a single point of contact for satellite and network
       installation issues.

    .  Allow iBEAM NOC to monitor traffic to the switch, server or other
       equipment for the following protocols, SNMP, FTP, Telnet, Ping,
       Traceroutes.

    .  Subject to prior approval and scheduling by NorthPoint, access to the
       data room for installation of the MaxCaster indoor components and the
       roof structure for installation of the MaxCaster satellite antenna.
       Installation must be supported by on-time access to the install areas.

    .  One "ACTIVE" twisted pair "analog" telephone line for termination to the
       iBEAM MaxCaster internal modem card. This is to allow for "out of band"
       monitoring and control of the iBEAM system.

       utilized a connection to the bit path must be provided.

    .  Access to 120 Volt AC from the Rack Power distribution harness for the
       server and the switch. In cases where NorthPoint has only DC power, iBEAM
       will be responsible for conversion from DC to AC.

    .  Adequate rack space for server, switch or other equipment. In addition,
       iBEAM will need to know the type and model of racks used in the data room
       for determining complementary shelves or rack guides for the server.

    .  Technical support and actual physical connection of the Layer 4 switch
       into the bit stream and associated patching if required. The Member is
       responsible for inserting the Layer 4 switch into the bit stream if
       required.

    .  Access to MaxCaster user logs for tracking purposes such as number of
       users on the network.

    .  UPS support for 14-Volt Amp power requirement for a period of 60 minutes
       to allow an orderly shutdown of the equipment.

    .  Keep area in which the MaxCaster is located at 80 or less degrees
       Fahrenheit and 75% or less, non-condensing relative humidity.

    .  Alert iBEAM during power outage or any Member Network outage, whether
       planned or otherwise, by telephoning iBEAM at iBEAM specified numbers.

    .  Inform iBEAM whether the Member network is Multicast enabled at any time
       during the contractual relationship.

    .  Provide iBEAM optimal connectivity into Member Network as mutually agreed
       by the Parties

                  Exhibit D to Agreement No. 093099NPoint

                               Portal Description

     Hosting:  iBEAM will host the co-branded portal page at no cost to Member.
     The portal will display links to live and on demand streams that are
     available on the iBEAM Network. iBEAM undertakes to use commercially
     reasonable efforts to acquire the license to use Content Provider name and
     Content on the portal page.  The portal will be accessible to all Internet
     users.

     Portal Branding and Creation:  iBEAM and Member will equally divide the
     cost of developing and maintaining the co-branded portal.  iBEAM will
     provide any project management and operational support necessary to roll-
     out and sustain the portal project.  iBEAM and Member will jointly agree on
     the design, content and operation of the portal.  iBEAM will develop a
     proof-of-concept portal at no cost to Member.  iBEAM and Member will
     jointly generate and fund the advertising associated with the portal.  The
     objective of this advertising is to drive demand for Member DSL service and
     iBEAM-delivered streaming media.

     DSL Promotion:  The sub-portal will contain static links to the streaming
     content of iBEAM content providers who have chosen to utilize the portal.
     When a Member user clicks on a link, they will see an interstitial message
     that informs them they are viewing an iBEAM enabled stream that is
     available to them because they are a Broadband user.  If a non-Member user
     clicks on a link, they will receive an interstitial message encouraging
     them to sign up for NorthPoint DSL service to get the high-fidelity version
     of the stream.

     Portal Promotion:  iBEAM will promote the Member sub-portal with all iBEAM
     content partners, as well as with iBEAM technology partners and joint
     iBEAM/Member ISP customers.  Also, iBEAM will include the Member sub-portal
     whenever reasonable in iBEAM end user marketing and promotion efforts.
