                                  SCOPE OF WORK

SECTION 1.  INTRODUCTION

1.1      SCOPE

         This Attachment  describes the technical  functionality and topology of
         the   domestic   telecommunications   requirements   of   Bridge.   The
         Sprint-supplied  Products and Services will provide  network  transport
         for the Bridge network.

1.2      OVERVIEW

         Sprint will  provide  Bridge with frame relay wide area  network  (WAN)
         transport for it's  router-based  network as well as  installation  and
         next day swap-out maintenance.  All other functions previously provided
         by Sprint will be delegated to and provided by Bridge.  These functions
         include router configuration,  router monitoring, and router management
         including  troubleshooting  and  resolution  of  all  software  related
         anomalies.

         Further,  Bridge shall undertake all transport  management,  including,
         but not  limited  to WAN  access  facility  sizing at  customer  sites,
         distribution  sites and St.  Louis  data  centers,  density of PVCs per
         hardware port on routers and switches,  and the number of WAN ports and
         associated access facilities  required at customer sites,  distribution
         sites and St.  Louis data  centers.  Bridge shall also order and manage
         dial backup functionality including equipment and analog telco lines at
         distribution  sites.  Sprint will mange the  ordering  of analog  telco
         lines at the client sites at time of initial installation.  Sprint will
         provide  maintenance  on associated  hardware at client sites only. All
         dedicated circuits will be ordered through Sprint.

1.3      SPRINT'S SOLUTION

         Sprint will provide all WAN transport  consisting  of dedicated  access
         from  Bridge  customer  sites,  distribution  sites and St.  Louis data
         centers.  Additionally,  Sprint will provide  installation and hardware
         swap-out  maintenance  of routers,  modems and DSUs at customer  sites.
         Sprint will also install Bridge servers at client sites. Maintenance of
         the servers will be provided by Bridge.

SECTION 2.  NETWORK OVERVIEW

2.1      NETWORK DESIGN OVERVIEW

         The network design for the Bridge network is summarized in Figure 2-1.

         [GRAPHIC OMITTED]

2.2      NETWORK NOTES

         The following list of assumptions and design  considerations  have been
         utilized  on  the  Bridge  Information   network  design  and  includes
         associated Sprint and Bridge responsibilities.

         o        Bridge will provide WAN bandwidth  management  for all network
                  facilities.  This includes remote customer sites, distribution
                  sites,  and the St. Louis data centers.  Bandwidth  management
                  includes but is not limited to  determination  of  appropriate
                  channel  sizes at all customer,  distribution

--------------------------------------------------------------------------------
Amendment 4                           A-2                                6/26/96

<PAGE>

                  and data center sites, numbers of channels,  PVCs per channel,
                  PVCs per port on  routers  and  switches,  number of ports per
                  switch or router, and number of switches or routers required.

         o        Bridge   will   use   Sprint-standard    circuit   utilization
                  guidelines.  Once a circuit utilization exceed 50%, procedures
                  will be initiated for the installation of additional  circuits
                  or  higher  bandwidth  circuits  on  the  affected  path.  The
                  objective is to have additional bandwidth installed so that no
                  circuit  utilization  exceeds  70% at  any  time  to  maintain
                  optimal network performance.

         o        Sprint will provide support for 100  installations  per month.
                  These can be any  combination of new  installations  or Bridge
                  reschedules installations.  The minimum number of installs per
                  day  is 6.  Installations  will  be  scheduled  during  normal
                  business hours, 8-5 CST.

         o        For new  installations,  Sprint will  install the Bay Networks
                  router and Netblazer,  the dial backup and  diagnostic  modem,
                  and the DSU.  Sprint  will  also  cable  the  newly  installed
                  equipment to the Bridge provided LAN.

         o        Sprint  will  configure  the  Telebit  NetBlazer  and load the
                  router with the final router configuration provided/created by
                  Bridge.  This configuration file will be located on a platform
                  provided by Bridge.  Bridge  must  provide  readily  available
                  remote access to this system. The configuration  files must be
                  available  two (2) business  days prior to site  installation.
                  The IP address and the required  directory  structure  must be
                  provided  to  Sprint  five  (5)  business  days  prior  to the
                  scheduled install date.

         o        Sprint will not troubleshoot any protocol problems,  including
                  protocol  problems  which occur  during  client site  hardware
                  installation.

         o        Bridge will perform a site acceptance when they receive a call
                  from Sprint  saying the site  installation  is complete.  Site
                  acceptance will be based on the following tests:
                  -        Telnet/Ping to router
                  -        Telnet/Ping to Net Blazer
                  -        Telnet/Ping to the Bridge servers
                  -        Check  operation  of dial back up by  unplugging  56k
                           line  and   determining   whether   the  dial  backup
                           connection to a distribution site is established
                  -        Check whether dial backup  disconnects  after the 56k
                           is restored
                  Should   Bridge  be  unable  to  perform   these   tests  upon
                  notification   from  Sprint  that  the  site  installation  is
                  complete, the site installation will be accepted by default.

         o        Bridge will be responsible for all network software upgrades.

--------------------------------------------------------------------------------
Amendment 4                           A-3                                6/26/96

<PAGE>

         o        Bridge will  provide all  maintenance  of Bridge  equipment at
                  collocation sites.

         o        Sprint will provide only next day swap-out  maintenance Monday
                  - Friday 8 am - 5 pm for  failed or  suspected  failed  CPE at
                  Bridge customer sites. The CPE technician will ensure that the
                  failed CPE is cabled  properly  and that the device  powers up
                  successfully.   Bridge   will  have   software   configuration
                  responsibility.

         o        Sprint  will not  provide  any router  network  monitoring  or
                  management.

         o        Bridge  will  report  all  appropriate  problems  to  Sprint's
                  Service  Management  Center (SMC). The Network Service Manager
                  (NSM) will support  resolution  of those  tickets that require
                  hardware maintenance.

         o        There will be charge for  dispatch to sites that are not ready
                  for  installation or swap-out  maintenance  (refer to contract
                  page B-3, item 6).

         o        Bridge will purchase all equipment through Sprint.

         o        Bridge will be responsible for working  directly with hardware
                  vendors  with  regard to  hardware  engineering  and  software
                  malfunction.

2.3      TOPOLOGY

         Sprint will  provide  Bridge with WAN  transport  for the frame  relay,
         router-based   network.   This  will  include  the   installation   and
         maintenance of Bay Networks routers,  Telebit routers, Sprint certified
         DSUs and CSUs and dial backup modems at client sites.

         Each  remote site will be provided  with  dedicated  access to Sprint's
         wide area network  (WAN).  The bandwidth of the access  channel will be
         determined  by Bridge.  The remote site will build one or two PVCs into
         Sprint's WAN which will  terminate at one of six regional  distribution
         sites. The  distribution  sites are collocated at Sprint POPs and house
         Telebit routers,  Bay Networks routers,  Cascade switches,  modem banks
         and CSUs. The Cascade switches are used both as a point of connectivity
         for GFIC  customers as well as an ATM  platform as Bridge  migrates the
         backbone   (distribution  site  to  St.  Louis  data  centers)  to  ATM
         transport.

         Each  distribution  site  Bay  networks  router  will act as a point of
         consolidation  for  Bridge  customer  traffic.  The  distribution  site
         routers will  terminate  traffic  from all  customer  sites within that
         region.  The routers will in turn route the traffic from those customer
         sites to  discrete  PVCs built from the  distribution  sites to each of
         Bridge's two St. Louis data centers.

2.4      TROUBLE RESOLUTION RESPONSIBILITY

         Bridge will provide all  proactive  monitoring  of network  facilities.
         Sprint  will  provide  only  reactive  maintenance.  Upon  report of an
         anomaly, Bridge will undertake the following diagnostic procedures.

         Client Sites

         AN Router -

                  Software - Bridge  will  access the  router  and  inspect  the
                  configuration   files.   Bridge  workstations  have  pull-down
                  screens that display the proper  configuration of the routers.
                  If a  configuration  is determined to be corrupted,  they will
                  rebuild the software configuration.

                  Hardware  - If an AN router  remains  in the  "boot" or "diag"
                  mode after being power  cycled,  it must be  replaced.  Bridge
                  will arrange to have power  cycling done by their client or by
                  their dispatch technicians. Other problems will be isolated by
                  using  the  router  logs,   Site  Manager,   and  the  network
                  management console.  When  troubleshooting  indicated a failed
                  router,  Sprint will be  contacted to open a ticket for router
                  replacement.

         CSU - If  diagnostics  reveal a good  router and  Sprint/telco  find no
         problems with the telco  access,  Bridge will open a ticket with Sprint
         for CSU replacement.

         Netblazer - If Netblazer alarm appears on Bridge's  network  management
         console,   Bridge  will  work  with  their  client  or  their  dispatch
         technician to power cycle the Netblazer. If the Netblazer fails to come
         up, Bridge will open a ticket with Sprint for Netblazer replacement.

         Modem - Bridge will determine  whether a problem appears to be with the
         local  dial line or the  modem.  If the dial line is tested  and proven
         functional,  Bridge will access the Netblazer for another view into the
         modem.  If these tests indicate a defective  modem,  Bridge will open a
         ticket with Sprint for modem  replacement.  If the dial line tests bad,
         Bridge will report the problem directly to the LEC.

         Cabling  - Telco  will be  responsible  for  wiring  to the  demarc  or
         extended  demarc  (when  telco  installed)  where  appropriate.   After
         accepted  installation,  Bridge will be responsible for troubleshooting
         all other customer premise wiring.

Amendment 4                           A-5                                6/26/96

<PAGE>

         Transport  - Sprint  will be the  point of  contact  for all  transport
         related problems, including amamolies associated with the LEC access on
         dedicated  circuits.  Bridge  will open a ticket with the SMC to report
         any transport problems.

         Distribution Sites

         Bridge will be responsible for the  troubleshooting  and maintenance of
         all distribution equipment located in Sprint POPs. This will include:

         o        Bay BLN Routers
         o        Cascade Switches
         o        Telebit Netblazer 40 Router
         o        Microcom Modems and QX chassis
         o        Adtran CSUs and chassis.  (Will be replaced by Visual Networks
                  CSUs)
         o        Ethernet transceivers
         o        UPS (May be Sprint provided. Procedures to be addressed)
         o        Dial lines (Both dial back-up and equipment management lines)
         o        Cabling associated with the above equipment.**

         ** Sprint   is   responsible   for   installing   and   replacing   all
         intra-cabinet/bay  and  inter-cabinet/bay   wiring.  Sprint  will  also
         connect such cabling to the equipment under Bridge direction at time of
         installation or replacement.

         Bridge will perform  troubleshooting of distribution site problems from
         their St. Louis  Network  Management  Center using  network  management
         tools such as HP OpenView, Bay Site Manager, etc.

         If  assistance is required  from local Sprint  operations  (such as for
         power cycling  equipment),  Bridge will open a trouble  ticket with the
         SMC.  The NSM or SE will then call the Sprint POP  stating  that Bridge
         has an open ticket and needs  assistance.  This will result in a charge
         to Bridge.

         If Bridge  determines  that equipment  needs to be replaced,  they will
         arrange for  shipment  and  schedule  the  dispatch  of a Bridge  field
         service  technician.  A trouble  ticket  will be opened with the SMC so
         that the Sprint personnel are aware and can provide access.

         If  there  is  a  failure  of  the  dial  lines   associated  with  the
         distribution   site,  Bridge  will  open  a  trouble  ticket  with  the
         appropriate  local exchange  carrier.  If the local exchange carrier or
         Bridge  field  service  requires  access to the  Sprint  POP, a trouble
         ticket will be opened with the SMC.

         For  routine or  preventative  maintenance,  Bridge will open a trouble
         ticket with the SMC in order to gain access to the Sprint POP.

Amendment 4                           A-6                                6/26/96

         Sprint will be the point of contact for all transport related problems,
         including  amamolies  associated  with  the  LEC  access  on  dedicated
         circuits.  Bridge  will  open a  ticket  with  the  SMC to  report  any
         transport problems.

2.5      DISPATCH PROCEDURE

         Upon notification of a network anomaly,  Bridge will attempt to isolate
         the problem.  If the problem  appears to be with either the client site
         hardware or WAN  transport,  Bridge  will open a ticket  with  Sprint's
         Service  Management  Center  (SMC) using  either the network or private
         line address.

         The SMC will forward the ticket to the appropriate transport fix agency
         (Private Line Service Center or Frame Relay Network Control Center). If
         the WAN tests  clean,  and the anomaly  appears to be  associated  with
         client site  hardware,  either the Network  Services  Manager  (NSM) or
         Systems  Engineer (SE) will submit  script to the Dallas  warehouse for
         overnight  shipment of the failed  hardware to the client site.  Bridge
         and/or the NSM will  coordinate  CPE dispatch  with the SMC on the open
         ticket.

         After  replacement,  Sprint will ship the failed router to Bay Networks
         for repair. After repair, Bay Networks will ship the router back to the
         Dallas depot for placement in the Bridge spares inventory.

2.6      CANADA SITES

         Sprint management practices and procedures will remain unchanged for an
         interim period for sites in Canada until these practices and procedures
         can be fully addressed.

NOTES:

1.)      Bridge is not  required to purchase  management  under this  Agreement.
         This pricing is  available as an option in the event Bridge  chooses to
         have Sprint manage their network.

2.)      Includes Telebit NetBlazer and Microcom modems or Teleblazer modems.

3.)      Valid only when the Telebit  NetBlazer and Microcom modem or Teleblazer
         modems are co-located with the router.

4.)      Pricing is valid only if Sprint provides  router and Transport  Back-up
         Management.

5.)      One annual  software  upgrade  is  included  in the  price;  additional
         software downloads after the first is * each per router.

         SOFTWARE RELEASE POLICY

         The latest Sprint  certified  software release is used for a new router
         network installation.

         Sprint reserves the right to upgrade Bridge software  revision level if
         the installed  revision  level is no longer  supported by Sprint.  This
         up-grade will be at no charge to Bridge.

         Sprint  reserves  the right to  up-grade  a  router's  software  to fix
         software  bugs in the existing  version.  This  up-grade  will be at no
         charge to Bridge.

         When adding new routers to an existing  network,  Sprint  reserves  the
         right to  install  the same  version  of the  software  running  on the
         existing network on the new routers.

         Sprint  support for software  revision  levels is  consistent  with the
         vendor's support for software revision levels.

         The one free  annual  software  up-grade  is for a major  release not a
         maintenance release.

         If the software  up-grade  requires  additional  hardware or a hardware
         up-grade, equipment and installation charges will apply.

         If Sprint  performs a software  up-grade in order to meet the  contract
         performance  criteria,  Bridge  will  not be  required  to pay  for the
         software upgrade.

         Sprint will provide adequate notice of any upcoming software upgrades.

                  a.)      The US Port Speed determined the "Base" port speed of
                           the  Global  Connectivity  Fee if it is lower than or
                           equal to the port speed of the  Global  Port to which
                           it is connected.

                  b.)      The Global Port speed  determines the "base" port for
                           the  calculation if it is greater than the US port to
                           which it is connected.  If multiple  Global Ports are
                           connected  to the  same US  port,  then  the  highest
                           Global  Port speed  determines  the  "base"  port for
                           calculation purposes.

II.      SPRINTNET SERVICES

The pricing components for Customer Link Series include the following:

         o        Recurring charges

                  -        Access  line  charge per  dedicated  access  facility
                           (DAF).
                  -        Network port charge per DAF.
                  -        Flat monthly usage charge.

         o        Non-recurring charges

                  Installation charge per DAF.

ONE-to-ONE Configurations

Unlike static  leased  lines,  each  ONE-to-ONE  site can take  advantage of the
global reach of SprintNet,  with  bidirectional  access to or from all SprintNet
locations  as well as  networks  in more  than  100  countries.  For  access  to
locations  other than the  specified  point-to-point  location,  standard  rates
apply.

Customers  may  contract  for more than a single  ONE-to-ONE  connection  at any
location.   ONE-to-ONE   is  primarily   available  to  customers   who  require
connectivity either between two non U.S. locations, or a U.S. location and a non
U.S.  location.  Customers  who  require  ONE-to-ONE  connectivity  between  two
locations within the U.S. only, must submit a special pricing request.

The flat monthly rate depends upon:

         o        Service level (national, regional or global).

         o        Connection speed (9.6 kbps - 256 kbps; varies by country).

         o        Location.

ALL-to-ALL Configurations

Global ports can do the following without incurring  additional traffic charges,
assuming a customer-specific network configuration:

         o        Initiate  calls with any other  defined  global,  regional  or
                  national ALL-to-ALL port.

         o        Initiate calls to an All-to-ONE hub port belonging to the same
                  customer.

ALL-to-ALL  permits customers to combine service levels. A large user can create
regional and global networks.  Whether a traffic charge is incurred depends upon
the call initiator's port classification and the geographic  boundaries the call
crosses.
