OVERVIEW

     The terms  "SAVVIS,"  "we," "us" and "our" as used in this report  refer to
SAVVIS  Communications  Corporation,  a Delaware  corporation,  formerly  SAVVIS
Holdings  Corporation,  and its subsidiaries,  except where by the context it is
clear that such  terms mean only  SAVVIS  Communications  Corporation.  The term
"Bridge" as used in this report refers to Bridge  Information  Systems,  Inc., a
Missouri  corporation,  which owns  approximately 49% of our outstanding  common
stock.

     We are a rapidly growing provider of high quality,  high performance global
data networking and  Internet-related  services to medium and large  businesses,
multinational  corporations and Internet service  providers.  We currently offer
the following services:

   o  MANAGED DATA NETWORKING  SERVICES that provide  secure,  high quality data
      communication   links   over  our   network   to   connect  a   customer's
      geographically  dispersed offices, known as intranets,  or to connect with
      its customers and suppliers, known as extranets.

   o  HIGH BANDWIDTH  INTERNET ACCESS SERVICES  including  dedicated  access and
      digital  subscriber  line,  commonly  known as DSL,  services and Internet
      security  services  which  connect our  customers  to the Internet at high
      speeds.

   o  COLOCATION   SERVICES   that   allow  our   customers   to  locate   their
      mission-critical content and networking hardware in our data centers which
      provide a highly secure, fault tolerant environment.

     We began commercial  operations in 1996,  offering Internet access services
to local  and  regional  Internet  service  providers.  In April  1999,  we were
acquired by Bridge,  a global  provider of real-time  and  historical  financial
information and news regarding stocks,  bonds,  foreign exchange and commodities
to the financial services  industry,  which it delivered to an estimated 235,000
trading terminals around the globe as of December 31, 1999. Bridge constructed a
highly  redundant,  fault  tolerant  network based on Internet  protocol and ATM
technologies  to  service  some  of  the  largest  financial   institutions  and
institutional  investors in the world. In September 1999, the SAVVIS ProActiveSM
Network was  created  through the  combination  of the network of Bridge,  which
network was  constructed  to meet the  exacting  requirements  of the  financial
services industry  worldwide,  and the SAVVIS network,  which was constructed to
provide  high  quality  Internet  access  in the  United  States.  Both of these
networks have been  operational  since 1996 and we refer to the combined network
as the "SAVVIS ProActiveSM Network."

     On February 18, 2000,  simultaneously  with the  completion  of our initial
public offering,  we acquired the Internet protocol network assets of Bridge for
total consideration of approximately $88 million and the employees of Bridge who
operate that  network were  transferred  to us. This  transaction  significantly
expanded  our  managed  data  networking  services,  which we began  offering in
September 1999.


                                        3
<PAGE>

     Pursuant to a network services agreement between Bridge and us, Bridge pays
us for the use of the SAVVIS ProActiveSM Network to deliver Bridge's content and
applications to over 4,500 financial  institutions,  including 75 of the top 100
banks in the world and 45 of the top 50  brokerage  firms in the United  States.
Since January 1996, Bridge has converted a substantial  portion of its customers
from less  technologically  advanced protocols to its Internet protocol network.
As of December 31, 1999, of Bridge's estimated 235,000  terminals,  an estimated
135,000 terminals were connected to the SAVVIS ProActiveSM  Network.  Bridge has
advised us that it intends to convert the  remaining  100,000  terminals  on its
other networks to the SAVVIS  ProActiveSM  Network over the next three years. As
Bridge converts terminals,  we expect it to order additional connections from us
under the network services  agreement.  In addition,  while over 4,500 financial
services  companies  are  customers  of Bridge and we only derive  revenue  from
Bridge for delivering  Bridge content and  applications to these  companies,  we
intend to  aggressively  market our services to occupants of the 6,000 buildings
connected to the SAVVIS ProActiveSM  Network, in particular to Bridge's customer
base. We currently  provide  Internet access services  directly to approximately
1,150 customers.

     The SAVVIS ProActiveSM Network architecture, which interconnects over 6,000
buildings in 83 of the world's major commercial cities in 43 countries, is based
on the following technologies:

   o  asynchronous  transfer  mode,  commonly  known as ATM,  which supports the
      transmission of all kinds of content and allows data to be prioritized;

   o frame  relay,  which  is  a  shared  network  technology  commonly  used in
      communications networks; and

   o  Internet protocol, a communications protocol that is a core element of the
      Internet  and is used on  computers,  but that cannot  currently  reliably
      deliver real-time data,  unless operated over an ATM network,  such as the
      SAVVIS ProActiveSM Network.

     Additionally,  our 83 city global system  connects to ten private  Internet
access  points,  which we call  PrivateNAPsSM,  where our network  connects to a
number of Internet  service  providers,  including Sprint  Corporation,  Cable &
Wireless  plc and UUNET,  an MCI  Worldcom  company,  allowing  us to bypass the
congested  public  Internet  access  points.  This network  design enables us to
provide  real-time data delivery and guarantee low latency and low data loss. It
also allows us to tailor our service  offerings to our  customers'  needs and to
offer a range of quality of service levels.

     We charge each customer an initial  installation  fee that typically ranges
from  $500 to $5,000  and a  monthly  fixed  fee that  varies  depending  on the
services  provided,  the bandwidth used and the quality of service level chosen.
Our customer  agreements  are typically for 12 to 36 months.  As of December 31,
1999, approximately 6% of our customer agreements, representing approximately 6%
of our revenues for the month of December  1999,  were  month-to-month  and were
able to be terminated on 30 days' notice.  We expect the proportion of customers
on  month-to-month  agreements will continue to decrease as we add new customers
and our sales force continues to pursue longer renewals.

     Currently,  our  revenue  is  derived  primarily  from  the  sale  of  data
networking,  Internet  access and colocation  services with Bridge  representing
approximately 80% of our total revenue.  Through December 31, 1998 and 1999, our
revenue was primarily derived from the sale of Internet access services to local
and regional Internet service providers in the United States.  Beginning in late
1998, we expanded our service offering to corporate customers as well.


RELATIONSHIP WITH BRIDGE AND WELSH CARSON

     Bridge  is a  privately  held  company  whose  principal  shareholders  are
investment  partnerships  managed by Welsh,  Carson,  Anderson & Stowe, or Welsh
Carson,  a sponsor of private  equity  funds with  extensive  experience  in the
communication and information services industries. On September 10, 1999, Bridge
sold in a private placement  approximately 25% of its equity ownership in SAVVIS
to existing stockholders of Bridge. In addition,  pursuant to an agreement dated
February 7, 2000,  Bridge on February 28, 2000 sold 6,250,000 shares for cash of
SAVVIS  common stock to an investment  partnership  sponsored by Welsh Carson at
the initial public offering price of $24 per share, totaling $150 million.


                                        4
<PAGE>

Bridge  currently  owns  approximately  49% of  our  outstanding  common  stock.
Investment  partnerships  sponsored by Welsh Carson currently own  approximately
38%  of  Bridge's   outstanding  voting  stock  and  approximately  16%  of  our
outstanding common stock.

     In connection with our acquisition of Bridge's  network,  we entered into a
10-year network services agreement with Bridge that commits Bridge to purchase a
minimum of $105 million,  $132 million and $145 million of network services from
us in 2000, 2001 and 2002, respectively.  Thereafter, Bridge will be required to
purchase at least 80% of its network  services from us, declining to 60% in 2006
through  the end of the  agreement  in  2010.  We will  incur  losses  from  the
operation  of the network  under the  network  services  agreement,  and had the
network services agreement been in effect in 1999, Bridge would have represented
approximately  83% of our 1999  revenues.  We have  instituted  a lead  referral
program  for  Bridge's  approximately  500 sales  representatives  worldwide  to
generate  sales leads for us. We also entered into a number of other  agreements
with Bridge,  including a master  establishment  and  transition  agreement,  an
equipment colocation permit, an administrative  services agreement,  a technical
services  agreement,  a GECC  Sublease and a local network  services  agreement.
Together  these  agreements  provided for,  among other things,  the transfer of
Bridge's  technical and support personnel to us, and our purchase from Bridge of
support and administrative  services,  including  help-desk services and network
operations  center  services.  These  agreements are described in more detail in
Item 13 of this report.


MARKET OVERVIEW

     Market  opportunity.  As the Internet  has emerged as a strategic  business
component,  investment in Internet services has begun to increase  dramatically.
According to International Data Corporation,  an independent  research firm, the
demand for U.S. Internet and e-commerce services was $2.9 billion in 1997 and is
expected to grow to $22 billion by 2002, a 50% compound  annual  growth rate. In
addition,  demand for data transport services is growing rapidly as evidenced by
International  Data  Corporation's  estimate  that Internet  service  providers'
corporate  access revenues will grow from $2.9 billion in 1998 to $12 billion by
2003, a 32.5%  compound  annual growth rate.  We believe a significant  Internet
market will continue to be Internet infrastructure and usage.

     Internet network services.  Since the  commercialization of the Internet in
the early 1990s,  businesses have rapidly  established  corporate Internet sites
and connectivity as a means to expand customer reach and improve  communications
efficiency.  Internet access service is now one of the fastest growing  segments
of the global  telecommunications  services  market.  According to International
Data  Corporation,  the number of Internet users worldwide reached 38 million in
1996 and is  forecasted  to grow to over 170 million by the year 2000.  Internet
access  services  represent  the  means  by  which  Internet  service  providers
interconnect  users to the Internet or to  corporate  intranets  and  extranets.
Access services  include dial-up access for mobile workers and small  businesses
and  high-speed   dedicated  access  used  primarily  by  mid-sized  and  larger
organizations.  In addition  to  Internet  access  services,  Internet  services
providers are increasingly providing a range of value-added services,  including
shared and dedicated web hosting and server colocation,  security services,  and
advanced  applications  such as  Internet  protocol-based  voice,  fax and video
services.

     Corporate data network services.  Other than Internet related services, the
majority  of  business  data  communications  today take  place over  private or
managed  corporate data and electronic data interchange  networks.  According to
International  Data  Corporation,  the market for data  network  services in the
United States grew from approximately $3.0 billion in 1997 to approximately $5.5
billion in 1998. International Data Corporation expects that the market for data
network  services in the United  States will  continue to grow  rapidly to reach
approximately $12.8 billion in 2003.

     Today, organizations employ local data networks, or local area networks, to
interconnect  personal computers and workstations.  The highly successful use of
local area networks for  information-sharing,  messaging and other  applications
has  led  organizations  to  aggressively  deploy  wide  area  networks,   which
effectively  interconnect local area networks and replicate their  functionality
across a much broader  geographic  area.  The demand for wide area  networks has
grown  as  a  result  of  today's  competitive  business  environment.   Factors
stimulating higher demand include the need to provide broader and more


                                        5
<PAGE>

responsive  customer service and to operate faster and more effectively  between
operating  units,  suppliers  and  other  business  partners.  In  addition,  as
businesses  become  more  global in  nature,  the  ability  to  access  business
information across the enterprise has become a competitive necessity.

     Convergence between the Internet and corporate data networking. Today, many
businesses are utilizing Internet-related services as lower-cost alternatives to
several  traditional   telecommunications   services.   The  near  ubiquity  and
relatively  low cost of the Internet  have  resulted in its  widespread  use for
specific applications, most notably web access and e-mail. Internet protocol has
become the communications  protocol of choice for the desktop and for local area
networks.  As a  result,  Internet  protocol  wide area  network  implementation
requires no protocol  conversion,  reducing overhead and improving  performance.
Many  corporations  are connecting  their remote  locations  using  intranets to
enable more efficient communications with employees, providing remote access for
mobile  workers  and  reducing  telecommunications  costs by  using  value-added
services such as Internet protocol-based fax and video-conferencing.

     Industry analysts expect the market for both Internet  protocol-based  data
networking  services and Internet  access to grow rapidly as companies  increase
their use of the Internet,  intranets,  extranets and privately managed Internet
protocol networks.  According to industry analyst Forrester  Research,  Inc., an
independent  research firm, the total market for Internet  services is projected
to grow from $6.2 billion in 1997 to approximately $49.7 billion in 2002.

     Rapid  growth in  e-commerce.  While  most  corporations'  early use of the
Internet was to establish an Internet marketing  presence,  businesses today are
using the Internet much more aggressively: to generate new revenues, to increase
efficiency  through  improved  communications  with  suppliers  and other  third
parties, and to improve internal communications.  The rapid growth of e-commerce
encompasses both  business-to-business and  business-to-consumer  communications
and  transactions,  and the projected growth of these markets over the next five
years is  dramatic.  Forrester  Research,  Inc.  projects  that the  market  for
business-to-business  e-commerce  will  grow  from $43  billion  in 1998 to $1.3
trillion in 2003. In addition, Forrester Research, Inc. projects that the market
for  business-to-consumer  e-commerce  will grow from $8 billion to $108 billion
over the same period.

     Outsourcing of Internet related  services.  In order to capitalize fully on
the new opportunities presented by the Internet and e-commerce,  businesses will
require  high   quality,   reliable  and  flexible   data   communications   and
infrastructure services capable of supporting mission-critical  applications. We
believe that an  increasing  number of businesses  will seek to outsource  these
services to third-party  providers for several reasons.  First, the rapid growth
of Internet-related  businesses has created a shortage of information technology
personnel skilled in Internet protocol and e-commerce development.  Second, many
companies believe that establishing leadership in their industry with respect to
Internet-related  services is important to the future of their  business.  Given
this  posture,  time  to  market  is  critical  and  turning  to a  specialized,
third-party   provider  can  often  shorten  time  to  market.   Finally,   many
infrastructure services require significant up-front investment.  Many companies
will choose to preserve their capital to invest in activities  that are integral
to  their  business  strategy  and  seek  to  develop  their  infrastructure  by
purchasing services rather than investing in networks, systems and equipment.

     Rapid growth in colocation and web site hosting. While in the past only the
largest companies provisioned their own data networking services, until recently
businesses of all sizes typically housed, maintained and monitored their own web
and content servers. As Internet-enabled  applications become  mission-critical,
larger and more difficult to develop and maintain and require increasing amounts
of  investment,  we believe a substantial  number of businesses  will  outsource
their colocation and web site hosting  requirements to third parties.  Forrester
Research,   Inc.  projects  that  the  web  site  hosting  business,   including
colocation, dedicated and shared hosting, will grow from less than $1 billion in
1998 to almost $15 billion by 2003. We believe that companies  seeking  Internet
protocol  expertise,  high levels of  security,  fault-tolerant  infrastructure,
local and remote support and the cost benefits of a shared  infrastructure  will
be most likely to outsource these services.

     Limitations of Internet protocol and the Internet.  Despite the remarkable,
rapid success of Internet  protocol,  the Internet  faces  limitations  that may
serve as a bottleneck  between the full  potential of Internet  protocol and its
use in  mission-critical  applications.  First,  in Internet  protocol  routing,
packet


                                        6
<PAGE>

data  travels  through  the network  without a  pre-defined  path or  guaranteed
delivery. Individual packets may travel separate paths and arrive at the network
destination at different  times.  Second,  Internet  protocol  packets cannot be
identified  as belonging to one class of traffic or another.  For example,  in a
given  flow  of  Internet  protocol  packets  it is  not  possible  to  separate
"real-time" traffic,  such as voice over Internet protocol,  from lower priority
traffic,  such as e-mail.  Each of these  issues  limits the utility of Internet
protocol for mission-critical,  real-time enterprise networks.  While we believe
that an improved  version of Internet  protocol will be implemented,  the timing
and efficiency of these improvements remain uncertain.

     Bottlenecks  at  network  access  points.  The  Internet  is a  network  of
networks.  Communication among these networks takes place at access points where
they interconnect.  Despite the near ubiquity of the Internet,  there are only a
few major public network  access  points.  However,  since the  introduction  of
network   access   points,   the  volume  of  Internet   traffic  has  increased
dramatically,  often overwhelming  network access points' capacity to handle the
smooth  exchange  of traffic.  The public  network  access  points are now space
constrained,  have inadequate  power and air  conditioning,  have poor security,
often employ older, less technologically  advanced switching technologies,  have
limited or no available  maintenance  or support  staff,  and are not  centrally
managed.  No single  entity has the economic  incentive or ability to facilitate
problem  resolution,  to optimize  peering of data  networks,  or to bring about
centralized   routing   administration.   As  a  consequence   of  the  lack  of
coordination,  and in order to avoid the  increasing  congestion  at the  public
network access points,  selected backbone providers have established connections
at private network access points, connecting to other backbone providers for the
exchange of traffic and bypassing public network access points.


BUSINESS STRATEGY

     Our objective is to tap the rapidly growing market for reliable, high speed
data  communications  and Internet  services.  In pursuit of this objective,  we
intend to:

     Provide a single source for managed data network  services and high quality
Internet services.  Data communications and the Internet are mission-critical to
thousands of businesses worldwide and, according to industry studies, the market
for these  services  continues to grow  rapidly.  Corporations  are  continually
expanding and enhancing existing networks and deploying new services in response
to this  growth.  By  providing a wide range of services  for both  Internet and
managed data networking  services,  we offer a single source solution to the key
challenges  faced by  corporate  information  technology  managers  implementing
Internet,  intranet  and  extranet  applications.  Since  the  requirements  and
internal capabilities of customers vary significantly,  we offer our services on
a  service-only  basis and a fully  managed  basis,  with service and  equipment
included.

     Capitalize  on Bridge  relationships  to penetrate  its customer  base.  We
intend to  aggressively  market our services to the over 4,500 Bridge  customers
already  connected to our network  through both our sales force and the over 500
Bridge sales  representatives  around the world. We provide incentives to Bridge
employees to refer Bridge  customers to us. Since Bridge  customers  are already
connected to our network, we believe we enjoy significant  time-to-market,  cost
and quality  advantages  and enhanced  customer  retention  when  delivering our
services to these customers.

     Target potential customers in buildings connected to our network. We intend
to actively  market our services to the  businesses in the over 6,000  buildings
worldwide  that are  connected to our network.  These  buildings  are  generally
located in central business districts of major cities and are typically occupied
by multiple  businesses.  Because our network is already in place,  we expect to
enjoy  time-to-market,  cost and quality advantages when delivering  services to
current and new customers located in these buildings.

     Expand our network and PrivateNAPsSM infrastructure.  We intend to leverage
the substantial  investments made in our network  infrastructure and service and
support   capabilities  to  service  new  customer  segments,   including  large
corporations in other targeted vertical markets,  medium and smallbusinesses and
Internet  service  providers.  We intend to continue to expand our data  network
infrastructure to connect new cities and new buildings to our network.  Over the
next two  years,  we expect to  establish  facilities  in 48  additional  cities
worldwide. We believe that this expansion will allow us to


                                        7
<PAGE>

continue to expand our customer base,  improve our service offerings and improve
our  economies  of  scale.  We also  intend to  continue  the  expansion  of our
PrivateNAPsSM  with the addition of three  PrivateNAPsSM by June 30, 2000. Given
the  high  volume  of  traffic  that is  carried  on our  network,  we are  also
evaluating  the purchase of local and long haul fiber to further  reduce network
operating costs.

     Grow  domestic  and  international  distribution  channels.  We  intend  to
aggressively grow our distribution channels. We expect to significantly increase
the size of our  sales  force  for both  global  data  networking  services  and
Internet access services in 2000 and enter into  distribution  arrangements with
companies  licensed to provide our services in markets  where we do not directly
hold such  licenses.  We will also attempt to establish  relationships  with our
Internet  service  provider  customers who are interested in  cross-selling  our
global data networking services to their existing customer base.

     Provide enabling  infrastructure for e-commerce  services.  We believe that
many of our target customers, particularly the financial services companies that
receive Bridge content and applications,  are aggressively  pursuing  e-commerce
strategies.  We believe  that our network  architecture  of ATM  technology  and
PrivateNAPsSM, highly available domestic and international dial access platforms
and security  services will enable  businesses to communicate with customers and
suppliers over the Internet and secure websites. As a result, we believe that we
are  well  positioned  to  help  our  customers  capitalize  on the  substantial
anticipated growth in e-commerce.

     Develop  and market new  services.  We intend to  continue  to develop  new
services,  such as voice and video,  that will enable us to further leverage our
network  infrastructure and our customer base. For example, we have deployed ATM
to the edge of our  network  and intend to  aggressively  deploy ATM  devices at
customer  premises  allowing for the provision of multiple network  applications
with  different  quality of service  levels over the same local access lines and
customer equipment.  The deployment of these devices will allow our customers to
combine  services that they may currently buy from multiple  vendors,  each on a
different  network,  onto our  network  at a  reduced  cost.  We are also in the
process of upgrading and  expanding  our data center  facilities to over 250,000
square feet of space,  and expect to offer complex web hosting services at these
facilities.  We intend to further expand our relationship with Bridge to develop
tailored  product  offerings  which bundle news,  financial  content and trading
applications  with our data  networking  services.  We also  intend  to  develop
bundled content or applications and network services with other trading partners
targeted at new vertical markets.


SAVVIS SERVICES

     We  believe  that we are  well  positioned  to  solve  the  major  problems
currently facing Internet and data networking customers.  We designed the SAVVIS
ProActiveSM  Network to offer a guaranteed,  superior level of  performance  for
both Internet and data networking services.  We deliver a comprehensive range of
high performance,  quality of service  differentiated  products,  including data
networking,   Internet  access,  intranets,   extranets,  colocation  and  other
services.

     A common feature among all of the services that we provide to our customers
is the substantial  flexibility to choose among a range of offerings,  including
on a service-only basis and a fully managed basis. On a service-only  basis, the
customer is  responsible  for the design and  integration of its network and the
purchase  of network  hardware,  relying on us only for network  services.  On a
fully  managed  basis,  we  are  responsible  for  the  design,  implementation,
integration and ongoing support of the customer's network.


 Global Data Networking Services

     The  SAVVIS   ProActiveSM   Network  provides  a  reliable,   high  quality
environment  to  transfer  private  corporate  data  among  offices,  employees,
customers and suppliers  because our network uses multiple  backbones,  switches
and local  connections  to attain a high level of redundancy and is monitored 24
hours a day, 365 days a year. Because all of our global data networking services
are carried  over a single  network,  we are able to offer  these  services on a
cost-effective  basis  relative to less  technologically  advanced  private line
networks,  while  providing  comparable  quality and  security  and  significant
improvements in redundancy, flexibility and scalability.


                                        8

     Managed Data  Networking.  Managed data  networking  services  provide data
communication  links over a shared  network  environment.  Because  we  operate,
manage and monitor  our global  network  end-to-end,  we are able to provide our
customers with higher  performance  and greater  reliability  than networks that
utilize the public  Internet.  Customers  can connect to our data network  using
ATM,  frame relay or Internet  protocol  technologies.  Customers  contract  for
connectivity  to our  global  network  and  configure  software-based  permanent
virtual  circuits that emulate much of the  functionality  of private lines, but
with improved  scalability  and redundancy and the ability to "burst" beyond the
stated capacity of the permanent virtual  circuits.  Our managed data networking
services  are  designed  for those  customers  that require a very high level of
quality and security for their networking services.

     Virtual  Private  Network  Services.  For customers who want to realize the
cost  benefits of a shared  network but do not require the level of  performance
and  security  of  our  managed   data   networking   services,   we  offer  our
Internet-based  virtual  private  network  services.  Virtual  private  networks
utilize the near-ubiquity of the Internet to provide cost-effective connectivity
for  businesses  with  large  numbers  of  sites,  sites  that do not have  high
bandwidth requirements,  sites that are in remote locations or mobile workers. A
typical   Internet-based   virtual  private  network  supports  dial-up  access,
resulting in extensive geographic coverage and, together with the implementation
of tunneling,  encryption,  authentication and access control technologies,  can
establish a secure  link  between the mobile  worker and the  corporate  network
environment.   One  of  our   primary   competitive   advantages   is  that  our
Internet-based  virtual  private  network  customers  are  served  by  our  high
performance network.

     Packet  Transport  Services.   We  offer   point-to-point  data  connection
services,  which  are  implemented  as  ATM or  frame  relay  permanent  virtual
circuits,   for  customers  requiring  high  bandwidth   point-to-point  network
communications.

     Dial Access. By the end of 2000, we plan to offer local dial access in over
20 U.S.  markets,  toll- free dial access for all other U.S.  markets as well as
international  dial access.  By the middle of 2001,  we expect to provide  local
dial access in approximately  100 U.S. cities,  increasing to approximately  300
U.S.  cities by the end of 2001.  Our dial access  service  will  enable  mobile
workers,  telecommuters and small-office and home-office users to connect to our
high quality global data network.  This service is targeted at those  businesses
with extensive  extranets designed for e-commerce  services and companies with a
significant number of mobile workers who demand reliable,  high-quality  dial-up
services.

 Internet Access Services

     We offer  our  customers  in the U.S.  a broad  range  of  Internet  access
services  designed to meet the varied needs of corporate  customers and regional
Internet service  providers.  Our Internet access services range from high-speed
continuous access provided by dedicated telephone circuits to lower-cost dial-up
services.  The principal  features of our Internet  access services are the high
performance,  reliability  and  flexibility  provided by the SAVVIS  ProActiveSM
Network that is connected to our system of PrivateNAPsSM  allowing our customers
to bypass the congested  public  Internet  access points.  We plan to make these
services  available outside the U.S. beginning in the third quarter of 2000. The
high  performance  of our  Internet  access  services  has been  verified by our
analysis of data collected by Keynote  Systems,  Inc.,  which showed that we had
the second best mean download time in 1999.

     Dedicated Access. We offer customers a range of bandwidth options, from 128
kilobits per second to 155 Mbps on a fully dedicated or burstable basis. We also
provide all required Internet protocol  addresses,  primary and secondary domain
name service, newsfeed service and network time protocol.

     Ethernet Service. For customers that seek a cost-effective 100% fiber optic
network technology for high-speed Internet access, we offer our 10 Mbps Ethernet
service.  Our  Ethernet  service  transmits  information  through  a  customer's
existing  local area network  router.  This service is an  intermediate  upgrade
between our 1.5 Mbps service and our fractional 45 Mbps service.

     DSL Service. For commercial  customers that seek cost-effective  continuous
connectivity for high-speed  Internet access, we offer symmetric DSL services at
speeds up to 1.5 Mbps. DSL services  transmit  information  through a customer's
existing copper telephone lines by encoding the information in a digital format.
We currently offer DSL services in 16 U.S. cities,  and we expect to add service
to approximately 12 additional cities by the end of 2000.


                                        9
<PAGE>

     Wholesale  Internet Access. We provide  wholesale  Internet access to local
and regional  Internet  service  providers  who use our network to connect their
customers to the Internet.

     Internet Security  Services.  For companies using the Internet,  protection
from  internal  and  external  threats to their  corporate  network is extremely
important.  We offer a broad  range of security  services  designed to provide a
customer with the ability to:

     o authenticate users attempting to gain access to its network;

     o prevent intruders from accessing its network;

     o protect the integrity of the content on its network; and

     o encrypt secured transmissions of company data through the Internet.

     We evaluate and assess a customer's security needs,  recommend  appropriate
security services,  and implement,  manage, monitor and maintain these services.
We also perform  security audits to find  deficiencies in a customer network and
in host computers attached to that network and recommend  appropriate  services.
Our security  services  utilize the  products  and  services of Netrex,  Inc., a
well-known Internet security provider.


 Colocation Services

     We offer customers a secure,  fault-tolerant environment in which to locate
their  mission-critical  content  and  networking  hardware.  We  provide  these
services  in data  center  facilities  that are  currently  being  upgraded  and
expanded to over 250,000 square feet of space. These state-of-the-art facilities
are  located  directly on our network to provide  high  quality,  cost-effective
Internet  access and hosting to the web sites of our  colocation  customers.  We
expect to complete  upgrades and expansions during 2000 in Boston,  London,  New
York, St. Louis,  Los Angeles,  San Francisco,  Dallas,  Chicago and Washington,
D.C.  By using  our  colocation  facilities,  customers  enjoy a highly  secure,
fault-tolerant  environment  and direct  access to our global  data  network and
avoid significant capital outlays required to construct such facilities on their
own.  Customers have physical and remote access to our colocation  facilities 24
hours a day, 365 days a year, to manage,  monitor and maintain their  equipment,
or they may engage us to provide support services.  Our colocation  services are
targeted  at content  providers,  Internet-centric  businesses  and  application
service providers.


SALES AND MARKETING

     We contact  potential new customers  through our direct sales force and our
recently implemented lead referral program. Our direct salespeople together with
our sales engineers develop sales proposals for potential new customers. After a
sale is completed and the services are  implemented,  the client  solutions team
assumes the management of the customer relationship, handling support issues and
selling additional services and connectivity as the customer's business grows.

     Direct Sales. Our direct sales force consisted of  approximately  100 sales
representatives  and sales  engineers in the U.S. as of December  31, 1999.  Our
direct sales force is specialized  along product lines,  which enables our sales
representatives  to develop an expertise in a specific  product area,  including
customer  applications and requirements.  This  specialization also allows us to
customize our sales  compensation  arrangements to the sales cycle,  revenue and
margin  characteristics of each product. All sales  representatives take part in
an extensive training program designed to develop in-depth  technical  expertise
so they can better understand  customers'  complex  networking needs and develop
customized solutions.

     Our sales force is divided between our Global Networking Sales Division and
our Internet  Access Sales  Division.  We employ a  distributed  sales model for
global networking sales to facilitate a consultative sales approach.  Our global
data  networking  sales force  currently  consists of twenty people based in six
major cities in the U.S. In contrast,  we have a centralized sales model for our
Internet  Access  Sales  Division.  Our Internet  access  sales force  presently
consists of approximately  114  representatives  based in Reston,  Virginia.  We
intend to locate additional  centralized  sales teams in Europe,  Asia and Latin
America by the end of 2001.


                                       10

     Bridge Lead  Referrals.  We expect to capitalize on our  relationship  with
Bridge, a major content provider to financial  services  companies,  to generate
sales leads in the financial  services market.  As of December 31, 1999,  Bridge
had approximately 500 sales  representatives  worldwide,  located in the world's
key financial centers.  These sales  representatives  support a customer base of
over 4,500 financial  services  companies already  connected to our network.  We
expect to be able to provide  these  businesses  with  additional  services in a
rapid,  cost-effective  and scaleable  manner. In addition to Bridge, we believe
that  additional  content  providers  will be  interested in  establishing  lead
referral programs.  A relationship with SAVVIS will enable a content provider to
deliver  its  service  in a  real-time,  high  quality  manner  and  provide  an
incremental revenue opportunity through a lead referral commission.

     Alternate Channels. In addition to relationships with content providers, we
have developed new distribution  arrangements with over 500 Internet-related and
communications  companies.  To help these companies  compete in today's changing
market, our alternate channels strategy brings companies network infrastructure,
sales and technical support and value added data services. Through our Web based
access our partners have access to our lead  referral  program,  free  marketing
materials  and  collateral  and an exclusive  incentive  promotion.  Our channel
partners  will  benefit by  generating  additional  revenues,  providing  a more
complete   service  bundle  and  reduce   customer  churn.  We  have  identified
distribution  opportunities with Internet service  providers,  competitive local
exchange carriers,  DSL companies and other  communications and Internet-related
companies in the United States, Europe, Asia and Latin America.

     Client  Solutions  Team.  Our  client  solutions  team is  responsible  for
customer relationship management. The team alerts customers when their bandwidth
utilization  approaches capacity and advises customers on methods to improve the
performance and security of their network using additional SAVVIS services. This
team is also able to cross-sell to existing customers additional services,  such
as  advising  a managed  data  networking  client  on  Internet  and  e-commerce
services.

     Marketing. Our marketing programs are designed to build national and global
awareness of the SAVVIS brand name and its  association  with high  performance,
high quality corporate data networking  services and Internet  services.  We use
brand awareness and direct marketing programs to generate leads,  accelerate the
sales process,  retain  existing  customers and promote new products to existing
customers. Our print advertisements are placed in trade journals, newspapers and
special-interest  publications.  We participate in industry trade shows, such as
Networld+InterOP, IT Expo and Internet World. At the 1999 Networld+InterOP show,
our virtual private network services were named the "Best of Show" for wide area
network  services.  We also  use  direct  mail,  e-newsletters,  widespread  fax
distributions,  surveys, telemarketing,  Internet marketing, on-line and on-site
seminars,  collateral materials,  advertising,  welcome kits and direct response
programs to  communicate  with  existing  customers  and to reach  potential new
customers.  Many of these marketing programs are co-funded by our suppliers. Our
marketing programs are targeted at information technology executives, as well as
senior  marketing  and  finance  managers.  We  closely  track  the  impact  and
effectiveness of our primary marketing programs.

     Sales Force  Automation.  We use our  proprietary  sales  force  automation
system to manage all pre-sales  communications  with our prospective  customers.
All  distribution  and tracking of sales leads occur through this system.  Sales
leads are imported from data sources such as corporate web sites, telemarketing,
direct mail and national advertising  campaigns,  and assigned regionally to the
desktops  of the  appropriate  sales  representatives.  All  contact  with these
prospects is documented in the sales force automation  system through every step
of the sales cycle, from initial contact to contract receipt. In addition,  this
system allows sales  management to monitor the sales  activity of their specific
sales  representatives  and generate  sales  forecasts  based on that  activity.
Further,  our sales force automation system tracks all marketing  communications
with the  prospective  customers,  allowing us to measure the  effectiveness  of
various  collateral  materials and marketing  campaigns in an effort to maximize
our marketing  dollars.  Lastly, our sales people use our sales force automation
system to track and manage their personal sales prospects and to send customized
packages of sales  literature,  brochures and faxes directly from their computer
desktops, thereby improving sales efficiency.

CUSTOMERS

     We currently provide services to approximately 1,150 customers. On February
18, 2000,  Bridge entered into a network  services  agreement with us and became
our largest  customer.  Assuming we had received the minimum  revenues under the
network services  agreement for the first year of the agreement in 1999,  Bridge
would have represented  approximately  83% of our 1999 revenues.  We expect that
Bridge will account for a significant percentage of our revenues during 2000. No
individual  customer  accounted for more than 5% of our revenues during the year
ended  December 31,  1999.  We also provide  services to many  Internet  service
providers and Internet-centric businesses.

     Our  contracts  with our  customers are typically for one to three years in
length. The Bridge network services  agreement is a ten-year  contract.  Many of
our customer contracts contain service level agreements that provide for service
credits should we fail to maintain specified levels of quality.


CUSTOMER SERVICE

     Our goal is to  provide  the  highest  level  of  customer  service  in the
industry.  We  believe  that  high  quality  customer  service  is  critical  to
attracting and retaining  customers and to satisfying  the rapidly  growing data
networking  requirements  and Internet  services needs of these  customers.  Our
comprehensive approach to customer service and satisfaction includes a focus on:

     o providing written guarantees of service quality;

   o providing  services on a service only basis and a fully managed basis, with
     service and equipment  included,  that are tailored to meet customer needs;
     and

     o providing   effective   management,   monitoring   and  support  for  our
customers' data networks.

     We believe our  network  architecture,  proprietary  routing  policies  and
industry leading service level  agreements  provide our customers with very high
service quality.  We are able to offer our customers different levels of service
priority  for their  different  data  transmission  needs over one  high-quality
network. For example, e-commerce and real-time applications,  such as voice, can
be assigned the highest level of quality of service,  while other  applications,
such as e-mail,  can be assigned a lower  priority of service.  By assigning the
highest  level of service only to  mission-critical  or real-time  applications,
customers can lower their overall data services costs without compromising their
data networking requirements.

     Customer Call Centers.  Customer support  personnel located in call centers
in St. Louis,  Missouri,  London, England and Singapore handle service inquiries
from our customers 24 hours a day, 365 days a year,  and provide this service in
eight  languages.  These  personnel are organized in client teams and are highly
trained to identify and resolve  customer  issues  rapidly and  completely.  Our
customer  call center  support  services  are  supplied to us by Bridge  under a
ten-year technical services  agreement.  Bridge reported to us that in September
1999 its call centers answered an average of 6,000 calls per week, maintained an
average hold time of under 15 seconds and  resolved 98% of customer  issues with
front-line support personnel. To track trouble tickets and customer information,
Bridge  uses a  proprietary  management  platform  based on  Vantive  enterprise
software,  a highly scaleable  platform for problem tracking and customer record
access and  maintenance  that is easily  accessible  by  personnel at all of our
network  operations  centers.  We use an integrated  client/circuit  information
database  that  allows  our  customer  support  personnel  to  quickly  access a
customer's profile from any of our support centers.  In our local markets, we or
Bridge  have  available  to us over 270 field  technicians  who are  experts  in
Internet  protocol,  Unix, NT and ISDN  technology and who are generally able to
respond to customer requests within two hours.

     Management,  Monitoring  and  Maintenance.  We provide our  customers  with
detailed  monitoring,  reporting and management  tools that allow them to review
their usage  patterns,  network  availability,  outage events,  latency and data
loss. These tools allow our customers to evaluate the performance of our service
against  our  service  level  guarantee  as  well  as  review   utilization  and
performance data to facilitate their network planning and design activities.

     Service Level  Agreements.  The  consistent,  reliable  performance  of the
SAVVIS  ProActiveSM  Network  enables  us to  provide  effective  service  level
agreements  to our  customers.  We believe  that  companies  unable to support a
commensurate  level  of  predictable  network  performance  will  not be able to
provide  service  level  agreements  with value to the customer or will do so at
substantial risk to their own business.


SAVVIS PROACTIVESM NETWORK INFRASTRUCTURE


 OVERVIEW

     The SAVVIS ProActiveSM Network reaches 43 countries,  with facilities in 83
major cities,  including 58 international cities and 25 U.S. cities. Our network
interconnects  over 6,000  buildings  worldwide and is based on ATM, frame relay
and Internet protocol  technologies.  In addition,  our network incorporates ten
PrivateNAPsSM,  which allows our Internet traffic to bypass the congested public
Internet access points.

     We have  designed  our  network  to enable us to offer our  customers  high
speed,  high quality  services,  as well as a range of quality of service levels
and multiple levels of redundancy. Our network is designed with:

     Open System  Architectures.  Our  network is based on ATM,  frame relay and
Internet protocol technologies. These are open systems networking protocols that
are in  widespread  use in data  communications.  Internet  protocol is the most
commonly used and fastest growing networking  protocol in the world. By carrying
Internet protocol on our network, we generally allow our customers to connect to
their customers,  suppliers and remote offices using equipment already installed
in their networks and the networks to which they connect. Additionally, by using
ATM and frame relay in our network,  we enhance network  utilization and quality
of service,  and we are able to easily communicate with third party networks for
the  delivery  of  traffic  on and off our  network  without  procuring  special
interface technologies or devices.

     Quality of Service  Differentiation.  Our network architecture allows us to
offer  and  guarantee  different  levels  of  service  priority  for  customers'
different  data  transmission  needs.  For  example,  e-commerce  and  real-time
applications,  such as voice,  can be assigned  the highest  level of  priority,
while other  applications,  such as e-mail,  can be assigned a lower priority of
service.  By  offering a quality of service  differentiated  product,  we enable
customers to select a  price/performance  combination  that is  appropriate  for
their  needs.  As we deploy ATM  devices at the  customer  premises in the first
quarter of 2000,  customers will be able to run multiple  applications,  such as
Internet access,  intranet and private voice,  over the same equipment and local
access, thereby saving on local network transport and equipment costs.

     High Reliability.  We utilize multiple,  redundant  circuits,  switches and
physical  locations  to  substantially  reduce the effects of a single  point of
failure  within our network.  This  redundancy,  combined with our switching and
routing equipment,  generally enables us to automatically reroute traffic when a
failure occurs,  resulting in higher overall network  performance and integrity.
Our  backbone  switches  also  incorporate  high  levels  of  equipment-specific
redundancies,  resulting in higher  levels of  availability  than those found in
basic routing platforms.  We also employ  uninterruptable  power supplies and/or
electric  generator back-ups at each switching  facility,  designed to limit the
impact of local power outages on our network.


 Global Network Components

     The components of our network include the following:

     Switching  Facilities.  There  are  over 200  Lucent  ATM and  frame  relay
switches,  providing a highly redundant switch backbone deployed  throughout the
SAVVIS  ProActiveSM  Network.  We have over 300 backbone  routers  installed and
there are approximately 10,500 Nortel routers located in office buildings and on
Bridge's  customers'  premises.  Our switches are located in secure  facilities,
which provide highly


                                       13
<PAGE>

reliable, direct access to high-speed telecommunications infrastructure. In each
switching facility, we rent space, install networking  equipment,  including ATM
or frame relay switches, routers and high-speed analog and digital modems.


     Backbone Capacity. Our network is designed with a highly redundant backbone
infrastructure,   including   diversely   routed  long  haul  and  local  access
connections from multiple  carriers.  We interconnect  our switching  facilities
through  high speed lines  leased from a variety of  carriers,  including  Qwest
Communications  International,  Inc., MCI Worldcom,  Inc. and  Broadwing,  Inc.,
formerly known as IXC Communications,  Inc. Our leased line connections range in
capacity  from  45  Mbps  through  155  Mbps  in  the  U.S.  and  up to 45  Mbps
internationally.  To enhance our  redundancy,  we lease ATM service  from Sprint
Corporation. This service is delivered using the highest quality of service mode
available and our service connections range in capacity from 45 Mbps through 620
Mbps.  The  combination  of our leased  lines and Sprint ATM  service  makes our
transmission  backbone highly redundant so that at least two diverse paths exist
between all of our switching facilities.  The "fault tolerant"  configuration of
our network  allows data  packets to travel on many  alternate  paths to connect
points on our network.


     PrivateNAPsSM.  For our customers'  Internet traffic, we have built private
network  access  points,  or  PrivateNAPsSM,  where we connect  to the  Internet
backbones operated by Sprint Corporation, Cable & Wireless plc and UUNET, an MCI
Worldcom  company.  At each of our  PrivateNAPsSM,  we are  connected  to  these
carriers  through transit  agreements that allow us to connect to their Internet
networks  for a monthly  fee.  Since we are a paying  customer  of each of these
Internet  backbone  providers,  we  believe we realize  better  response  times,
installation  intervals,  service levels and routing  flexibility  than Internet
service   providers  that  rely  solely  on  free  public  or  private   peering
arrangements. We currently operate ten PrivateNAPsSM in the U.S. In addition, to
enhance  our carrier  redundancy,  at each of our  PrivateNAPsSM,  we connect to
other Internet  backbones through peering  arrangements  where each party to the
peering  arrangement agrees to carry the other party's traffic for free. We have
peering  arrangements  in  place  with  AboveNet  Communications,  Inc.,  DIGEX,
Incorporated,  Exodus  Communications,  Inc.,  Frontier  GlobalCenter,  Level  3
Communications,  LLC, PSINet Inc. and Williams  Communications Group, Inc. These
peering  arrangements  allow for  settlement-free,  direct  connections  between
networks,  where local access  charges are  generally  split evenly  between the
applicable parties.  Smaller Internet service providers typically connect to our
network through transit agreements that allow them to connect to our network for
a fee.


     Our  PrivateNAPSM   architecture  combined  with  our  proprietary  routing
policies  enables  us to route  customer  traffic  directly  onto  the  Internet
backbone  of its  destination  for a  substantial  portion  of  global  Internet
addresses.  This network  architecture allows our customers' Internet traffic to
generally  bypass  congested  public  Internet  network access  points,  thereby
reducing data loss and latency and improving  reliability  and  performance.  In
addition,  customers  directly  connected to the same  PrivateNAPSM  get one-hop
access, meaning their data pass through only one router, when communicating with
each other, and two customers connected to different PrivateNAPsSM enjoy two-hop
access,  meaning  their data pass through only two routers,  when  communicating
with each other, in both cases completely bypassing the public Internet.


     Dial Access  Platforms.  We are  currently  deploying 25 Nortel dial access
platforms  in over 20 cities in the U.S.,  which we expect to have  completed by
the end of 2000. By mid-2001, we plan to deploy dial access in approximately 100
U.S. cities, increasing to approximately 300 U.S. cities by the end of 2001. Our
dial coverage may be  supplemented by toll free dial access where we do not have
local dial access,  and by the end of 2001 the platforms are expected to contain
over 20,000 ports.


     Colocation.  We are in the process of upgrading  and expanding our Internet
colocation  data center  facilities  to over  250,000  square feet of space.  We
expect to complete the upgrade and expansion during 2000 in Boston,  London, New
York, St. Louis,  Los Angeles,  San Francisco,  Dallas,  Chicago and Washington,
D.C. All of these  facilities will be served by multiple 2.5 gigabits per second
connections  for  local  access.   Development  is  underway  to  elevate  these
facilities to state-of-the-art  levels with high availability,  mission-critical
environments, including uninterruptable power supplies, back-up generators, fire
suppression,   separate  cooling  zones  and  seismically  braced  racks.  These
facilities will be accessible 24


                                       14
<PAGE>

hours a day,  365 days a year,  both  locally and  remotely,  and will have high
levels of  physical  security.  These  facilities  include  two fully  redundant
colocation  facilities  in St.  Louis,  Missouri,  each of  which  will  contain
approximately  90,000  square  feet,  approximately  60,000  of  which  will  be
subleased to Bridge.


 Network Operations Centers

     Our global network operations center,  which is owned and managed by Bridge
and located in St.  Louis,  Missouri,  operates 24 hours a day, 365 days a year,
and is  staffed by over 20 of our  skilled  technicians.  We also have  regional
network  operations  centers in London and  Singapore.  These  regional  centers
operate for  ensuring  backup for the St.  Louis  facility.  From these  network
operations centers, we remotely monitor the components of the SAVVIS ProActiveSM
Network,  including  our  PrivateNAPsSM,  and perform  network  diagnostics  and
equipment  surveillance.  The  network  operations  centers  use  sophisticated,
proprietary  network  management  platforms  based on the Lucent  NavisCore,  HP
OpenView,  and Nortel  Optivity  programs  to monitor  and manage our  switching
facilities and our routers.


TECHNOLOGY OVERVIEW

     Private networks.  Private networks typically comprise a number of private,
leased lines that interconnect  multiple corporate locations.  The advantages of
private lines include quality,  since capacity is reserved for the exclusive use
of the network owner, and security, since the owner's data transmissions are not
commingled with those of other  customers.  Private line networks have been most
popular in the U.S.,  where capacity prices are lowest.  While private lines are
typically secure and reliable,  they do not use network capacity efficiently and
are not flexible or scaleable as changes in network topology are implemented.

     Shared networks.  Until recently,  prices for long-haul  telecommunications
capacity  outside  of  the  U.S.,  particularly   international  capacity,  were
relatively  expensive.  Since the  advent of data  networking,  only  users with
extremely  high  capacity  requirements  invested  in private  networks in these
locations.  Most other users employed shared  networking  technologies,  whereby
multiple corporate  locations would be interconnected with the data network of a
major  telecommunications  carrier or value-added  network service  provider for
carriage to the appropriate destination.

     X.25 was an early open shared network protocol that was designed to support
mission-critical  communications  over analog networks.  X.25 has been extremely
popular  outside of the U.S.,  where until  recently  private line networks have
remained  expensive,  and in  developing  markets  where the  telecommunications
infrastructure  is  sometimes  unreliable.  X.25  contemplates  extensive  error
detection  and data  recovery  processes,  which  slows  the  effective  rate of
transmission.

     Today,  ATM, frame relay and Internet protocol are driving the migration of
traffic  from  private  line  networks  to shared  networks  and from older open
protocols such as X.25 to newer architectures.

     Frame Relay.  Frame relay  evolved  from X.25  networks and today is widely
used  for  applications  such  as  local  area   network-to-local  area  network
communications.  Unlike  X.25,  frame relay does not  perform any complex  error
detection  or error  recovery of data.  As a result,  it is a simpler and faster
technology.   Frame  relay  circuits  are  effective  to  create  a  network  of
interconnected  sites because each site needs only one link into the frame relay
network to  communicate  with all other  sites.  Frame relay is less costly than
point-to-point  private networks,  and its  software-defined  "virtual circuits"
make it easier to alter network  topology as connectivity  requirements  change.
One  limitation  of the frame relay  protocol is its  application  for real-time
services.  Frame relay  packets are variable in length,  and as large data files
transit the  network  they can cause  delays at key  aggregation  and  switching
points,  often causing other traffic to be delayed.  These delays can materially
degrade the quality of real-time services such as voice and video.

     ATM. The ATM protocol was specifically designed to support the transmission
of all types of content, including data, video and voice, over a single network.
ATM generally has the ability to prioritize  cells to ensure that real-time data
takes priority over less  time-sensitive  material when  transiting the network.
This enables service providers to offer service guarantees with a greater degree
of confidence and  facilitates the  introduction of real-time  services that are
difficult under other protocols.


                                       15
<PAGE>

Additionally,  ATM  data  cells  are  small  and  fixed  in  size,  facilitating
high-speed  line  transport  at speeds up to 2.5 billion  bits per  second.  One
limitation of ATM is that the benefits created by the small, fixed nature of ATM
cells also create incremental traffic on the network. Each cell requires its own
identification  and  addressing  information,  which is repeated in each of many
individual ATM cells that comprise a given data transmission. The replication of
this  "header"  information  generates  additional  overhead  for  the  network,
requiring the network operator to provision additional transmission capacity.


     Internet Protocol. Internet protocol is a simple, highly scaleable protocol
that is a core  element  of the  architecture  of the  Internet  and can be used
across most network technologies in use today. Internet protocol has also become
the  communications  protocol  of choice  for the  desktop  and the  local  area
network,  thus data  networking  over  Internet  protocol  requires  no protocol
conversion,  reducing overhead and improving performance.  The protocol does not
distinguish  among  classes of  traffic,  which  limits  its  ability to deliver
real-time services.


     Our Network. We have built the SAVVIS ProActiveSM Network to take advantage
of the  rapid  growth of  Internet  protocol  in  corporate  networks,  to offer
customers the ability to run multiple  applications  on a single  network and to
allow  customers  to choose the quality of service  level which best meets their
needs.  By building our network to run Internet  protocol over ATM, we allow our
customers to overcome the  limitations  of Internet  protocol and  designate the
level of priority to be accorded to their traffic.


COMPETITION


     The markets that we serve are intensely competitive. In addition, we expect
to  face  significant   additional  competition  in  the  future  from  existing
competitors  and new  market  entrants.  Many of our  competitors  have  greater
financial,  technical and marketing  resources,  larger customer bases,  greater
name  recognition and more  established  relationships in the industries that we
operate in than we do.


     We believe that a highly reliable network infrastructure,  a broad range of
quality  products and services,  a knowledgeable  sales force and the quality of
customer support are the primary competitive factors in our targeted markets and
that price is generally secondary to these factors. We believe that we presently
are well positioned to compete  favorably with respect to most of these factors.
Our current and potential competitors in our targeted markets include:


     Data Networking Companies. Several data networking companies such as Equant
N.V., Infonet Services Corporation,  Concert Management Services Inc. and Global
One offer data  networking  services  to  business  customers  worldwide.  These
services include ATM and frame relay,  private line, Internet access and network
outsourcing.  These companies have significant  experience in offering  tailored
services and market their  expertise  in  providing  these  services and related
technology.  For example,  Reuters Group plc and Equant N.V. recently  announced
that they intend to form a joint venture for the purposes of offering IP network
services  to the  financial  services  industry.  There are also a number of new
entrants,  such as Digital Island Inc.,  that are targeting  specific  niches to
deliver customers' data traffic worldwide.


     Internet Service  Providers.  Our current and potential  competitors in the
market include Internet service providers with a significant regional,  national
or global presence targeting business customers, such as Apex Global Information
Services,  Inc.,  AT&T Corp.,  Cable & Wireless  plc, GTE  Internetworking,  ICG
Communications,  Inc.,  Intermedia  Communications  Inc.,  PSINet  Inc.,  Sprint
Corporation,  UUNET, an MCI Worldcom company, Concentric Network Corporation and
Verio Inc. Many of these companies are developing Internet-based virtual private
network  services that attempt to replicate some or all of the  functionality of
our managed data networking services.


     Telecommunications  Carriers.  Many large  carriers,  including AT&T Corp.,
British  Telecommunications  plc,  Cable & Wireless  plc,  MCI  Worldcom,  Inc.,
Deutsche Telekom AG and Sprint  Corporation,  offer data networking and Internet
access services. They compete with us by bundling various services such as local
and long distance voice,  data transmission and video services to their business
customers.  We believe  that there is a move toward  horizontal  integration  by
telecommunications


                                       16
<PAGE>

companies  through  acquisitions  of or joint  ventures  with  Internet  service
providers  to meet the  Internet  access  and data  networking  requirements  of
business customers.  Accordingly,  we expect to experience increased competition
from these telecommunications carriers.

     Other   Competitors. Because  we  offer  a  broad  range  of  services,  we
encounter  competition  from  numerous  businesses  which  provide  one  or more
similar  services.  For  example,  we  compete  with  companies  such  as Exodus
Communications,  Inc.,  Qwest Communications International Inc., Global Crossing
Ltd.,  DIGEX,  Incorporated  and  Level 3 Communications, Inc. in the colocation
facilities market.


REGULATORY MATTERS

     As with  any  provider  of  global  data  networking  and  Internet  access
services,  we face  regulatory and market access  barriers in various  countries
resulting from restrictive laws,  policies and licensing  requirements.  Our six
major markets consist of the United States, the United Kingdom, Germany, France,
Italy and Japan.  Data  networking and Internet  access services are now open to
competition in all of these foreign markets,  but a license is required,  except
for France  where no license is  required.  We believe  that we are  licensed to
provide data networking and Internet access services as an independent  operator
under the  applicable  telecommunications  regulations in the United Kingdom and
Italy,  that in France we are  authorized to provide such  services  without any
license and that in Germany we have notified the necessary  authorities to allow
us to provide such services.  In Japan,  we are currently  authorized to provide
data  networking  services  only to  Bridge  and are in the  process  of  making
application for the appropriate license to offer services to third parties.

     In most other  countries  that we  believe  represent  significant  revenue
potential,  our data  networking  and Internet  access  services are now open to
competition,  although  in most  cases a license is  required.  In some of these
countries,  including Australia,  Austria, Belgium, Denmark, Finland, Hong Kong,
Luxembourg, The Netherlands, New Zealand, Norway, Puerto Rico, Spain, Sweden and
Switzerland,  we are authorized to provide data  networking and Internet  access
services  to Bridge  and  third  parties.  However,  in the  remainder  of these
countries,   including  Brazil,   Canada,   Chile,  India,   Indonesia  and  the
Philippines, we are authorized to offer data networking services only to Bridge,
although with respect to Canada,  we have already applied to provide services to
third  parties.  Our  business  plan does not  contemplate  selling  significant
services outside of the U.S., except to Bridge, in the near term. Therefore,  we
do not believe that our  inability to offer  services to third  parties in these
countries is significant.

     In addition,  we face regulatory and market access barriers in countries in
which we do not  operate  but in which we have an  obligation  to  purchase  the
Bridge Internet protocol network assets that we have not already acquired in the
Bridge  asset  transfer.  These  Bridge  network  assets  generally  will not be
transferred   to  us  as  part  of  the  Bridge   asset   transfer   because  of
telecommunications licensing or other regulatory requirements.

     We are in the process of seeking regulatory  approvals in some countries to
offer services to Bridge and third parties,  including Greece, Ireland, Hungary,
Taiwan,  and  Venezuela  and with respect to Mexico,  Bridge  only.  Although we
expect the asset transfer to occur in these countries  within one year after the
completion  of our initial  public  offering  we cannot  assure you that we will
obtain any of these  approvals.  We do not  believe  that the  failure to obtain
these  licenses will have a material  impact on our revenues as we do not expect
revenues from non-U.S. customers to be substantial in the near term.


 World Trade Organization Agreement and its Implications

     On February 15, 1997, 69 countries at the World Trade Organization  reached
an agreement to liberalize  market access and  introduce  national  treatment in
basic  telecommunications  services. Since then, two of the 69 participants have
submitted  improved  basic  telecommunications  schedules  and three World Trade
Organization  members who did not participate in the negotiations have submitted
commitments,   bringing   the   total   number   of   governments   with   basic
telecommunications  schedules to 72. In February  1998, the results of the World
Trade  Organization  negotiations on market access for basic  telecommunications
services  formally  entered  into  force and  became  binding  on the  signatory
countries.


                                       17
<PAGE>

     Despite  the  World  Trade  Organization  agreement,  regulatory  obstacles
continue to exist in a number of  signatory  countries.  First,  some  signatory
countries made only limited  commitments in terms of the services that they were
willing to  liberalize  and the  timeframe  in which they were willing to do so.
Second,  some less  developed  signatory  countries  are not well  prepared  for
competition  or for  effectively  regulating a liberalized  market;  gaining the
requisite experience and expertise is likely to be a long and difficult process.
Finally,   even   in   liberalized   countries,   there   remains   considerable
"post-liberalization  red tape," such as complicated  licensing  rules,  foreign
ownership  limits,  high fees and undeveloped  competition  and  interconnection
safeguards.

     Corporate  Presence.  In a number of  jurisdictions,  we are  permitted  to
provide data  networking or Internet  access  services to local  customers  only
after  first   establishing  a  corporate   presence,   by  way  of  either  the
incorporation of a subsidiary or the registration of a branch or  representative
office.  We have  established or will establish such a local presence in each of
the jurisdictions where such a presence is legally required.


 Regulatory Analysis by Service Type

     Data Networking Services. The core of our data networking services business
is  providing  managed data  networking  services to  corporate  customers.  The
managed data networking services that we provide are generally  characterized as
data transmission  services or value added services for licensing  purposes.  We
are  authorized  by law or by  individual  license  or a  general  authorization
obtainable by simple notification or declaration by an automatic "class" license
to  provide  these  services  in the  foreign  countries  in which we  expect to
generate  significant  revenue from data  networking  services.  In the European
Union member countries, such services may be provided upon the satisfaction of a
simple  registration,  notification or authorization  procedure,  in some cases,
without the need for any formality.

     Internet Access  Services.  The Internet access services that we provide in
the U.S. do not require any authorization.  The Internet access services that we
offer  outside of the U.S.  generally  do not require any  authorization  beyond
those required for managed data  networking  services and value added  services.
However,  because the regulation of Internet access is ill-defined or in flux in
some  countries,  there is a risk that customers are using our network to access
the Internet in countries that may prohibit,  or wish to prohibit,  such access.
We may limit this risk by  discontinuing  such access if  measures  are taken or
threatened by the pertinent  authorities  to restrict the use of our network for
Internet access.


 Substantive Regulation in Key Markets

     The regulatory regimes applicable to the United States, the United Kingdom,
Germany,  France, Italy and Japan, which will be our six major markets following
the Bridge asset transfer, as well as that of the European Union, are summarized
below.

     United  States.  We believe that the  regulatory  framework  governing  the
provision  of  telecommunications  services in the United  States  permits us to
offer all of our planned data  networking  services  without  significant  legal
constraints.  We provide these services on a resale basis or a facilities basis.
To the  extent  that any of these  planned  or  future  services  require  prior
authorization,  either by the Federal Communications Commission, or FCC, or by a
state public utility  commission,  we believe there is no significant  risk that
such an application  would be denied or would face processing  delays that would
have a material adverse effect on us.

     Nevertheless, services offered over the Internet or using Internet protocol
may present  distinct  regulatory  issues,  as is also the case in the  European
Union. The regulatory classification and treatment of some of these services has
not been resolved  authoritatively in the United States, and it is possible that
various Internet-related  services will be subject to prior authorization and to
as yet undefined  terms and conditions  under which such  authorizations  may be
granted.

     The  provision  of basic  telecommunications  services on a common  carrier
basis is subject to  regulation  in the United  States.  An entity that provides
such services on a common  carrier  basis is classified as a  telecommunications
carrier. Interstate and international common carrier services provided


                                       18
<PAGE>

by a  telecommunications  carrier  are subject to the FCC's  jurisdiction  under
Title II of the Communications Act. Intrastate  telecommunications  services are
subject to regulation by the relevant state Public Utility Commission.

     We believe  that the  products  and  services  we offer are not  subject to
regulation,  but  there is some risk  that the FCC or a state  commission  could
determine that our products and services should require  specific  authorization
or be  subject  to  other  regulations.  If  that  were  to be the  case,  these
regulatory   requirements  could  include  prior   authorization   requirements,
tariffing   requirements  and  the  payment  of  contributions  to  federal  and
state-created  subsidy mechanisms  applicable to providers of telecommunications
services.  Some of these contributions would be required whether or not we would
be subject to authorization or tariff requirements.

     There  also is some  uncertainty  about  the  regulatory  status  of  voice
services  provided on data  networks.  If we were to offer voice services in the
future,  there is some risk that those  services  could be subject to regulation
and that those  services could be treated  similarly to voice services  provided
over  conventional  circuit-switched  network  facilities for purposes of making
payments to local  telephone  companies for origination and termination of calls
and for other purposes.

     European Union. In the last ten years, the European Union has established a
comprehensive  and  flexible   regulatory   system,   culminating  in  the  full
liberalization of  telecommunication  networks and services effective on January
1, 1998.  By that date,  ten European  Union member  countries  were required to
adopt  a  fully  liberalized  telecommunications  regime.  These  countries  are
Austria,  Belgium,  Denmark,  Finland,  France, Germany, Italy, The Netherlands,
Sweden and the United  Kingdom.  The five remaining  European  Union  countries,
Luxembourg,  Ireland,  Spain,  Portugal  and Greece,  were  allowed a derogation
allowing  them to delay  the  full  liberalization  of their  telecommunications
regime  until  a  later  date.   As  a  result,   Luxembourg   liberalized   its
telecommunications  regime on July 1, 1998;  Spain and  Ireland  liberalized  on
December 1, 1998; and Portugal liberalized on January 1, 2000.  Currently,  only
Greece is not required to have a fully  liberalized  telecommunications  regime.
Greece is required to liberalize by December 31, 2000.

     The process of opening up the  telecommunications  markets in the  European
Union  was  achieved  through  European  Union  legislation  called  directives.
Directives are addressed to and binding on European  Union member  countries and
require  implementation into national law. There are two types of European Union
directives  relating to  telecommunications:  first,  directives  adopted by the
European  Commission  aimed at liberalizing  European Union markets and, second,
directives  adopted by the European Council aimed at ensuring that a minimum set
of harmonized rules, to ensure fair competition, applies throughout the European
Union.  All 15 European Union member countries were obligated to incorporate the
principles  contained in these directives into their  respective  domestic legal
frameworks.  However,  the  impact of the  European  Union  directives  has been
affected  in some  cases by late or  inadequate  implementation,  as well as the
irregular  enforcement by the domestic  regulatory  authorities of some European
Union member states.

     United Kingdom. The  Telecommunications Act of 1984 provides the regulatory
framework  for  the  provision  of  telecommunications  services  in the  United
Kingdom.   The  authorization   regime   established  by  this  act  is  largely
infrastructure based, meaning that "systems" are licensed, with licenses for the
provision of specific services being the exception.  This  authorization  regime
also is based on licenses, rather than regulations or other generally applicable
instruments.  There are two  broad  types of  licenses,  individual  and  class.
Finally,  with minor  exceptions,  regulatory  treatment under this act does not
hinge on whether the license applies to data or voice.

     We provide our managed data networking services and value added services on
an international basis under the Telecommunications Services License, which is a
class license. This license authorizes the provision of fixed telecommunications
services  of  any  description,   other  than   international   voice  services,
broadcasting and conditional access services. This license allows the connection
of the licensee's  telecommunications  system to essentially  any other licensed
system, and allows the commercial supply of services to third parties from up to
20  premises.   Internet   access   services  are  not  subject  to   additional
service-specific regulation.


                                       19

     Germany. The legal framework for the deregulation in the telecommunications
sector in Germany was transformed by the  Telecommunications  Act of 1996, which
became  effective on August 1, 1996,  and its  implementing  ordinances  adopted
since then. This act has liberalized most telecommunications  services,  subject
to a licensing  regime that is in conformity with European  Community law in all
material  respects.   However,  some   telecommunications   services,   such  as
asynchronous DSL, are not liberalized. Nevertheless, the managed data networking
services and value added  services that we offer can be provided in Germany upon
notifying the regulatory authorities, which we have done.

     France. The legal framework for regulation in the telecommunications sector
in France was transformed by the  Telecommunications  Act of 1996,  which became
effective on July 28, 1996, and subsequent decrees on interconnection, universal
service, numbering,  licensing and rights-of-way.  This act has liberalized most
telecommunications services, subject to a licensing regime that is in conformity
with European  Community law. The data networking  services we provide,  whether
managed data networking  services or Internet access services,  currently do not
require any form of authorization.

     Italy.  Pursuant to law No. 103/1995 and subsequent decrees,  the provision
of telecommunications  services in Italy to the general public is subject to the
granting of two specific authorizations from the Ministry of Communications. One
authorization relates to provision of telecommunications services through direct
access to the  public  network,  including  Internet  access  services,  and one
authorization relates to provision of packet- and circuit-switched data services
or simple resale of capacity, including data transmission.  For the provision of
telecommunications  services  through  switched access to the public network,  a
notice must be filed with the  Ministry of  Communication.  Savvis has  received
both of the above referenced authorizations and provided the requisite notice.

     Japan. The legal framework for regulation in the telecommunications  sector
in Japan is the  Telecommunications  Business  Law.  This law requires a Special
Type 2 License  if a company  makes its  international  communication  facility,
including privately leased international lines, available to any third party for
the purpose of  telecommunication by that third party. In this context, the term
"telecommunication" encompasses the act of data transmission.  Accordingly, if a
company provides its customers access to an overseas database through its leased
lines,  it will be required to obtain a Special  Type 2 License.  However,  if a
company  were to  replicate  the  database  in Japan  and  permit  access to the
database from within the country, the Telecommunications  Business Law would not
apply,  even if all the information  were  transmitted  directly to the database
from an overseas  parent  company or  subsidiary.  Under the  Telecommunications
Business Law, information transfers exclusively between a parent company and its
subsidiary are exempt from licensing.  Moreover,  if a company provides Internet
access  services  directly  or  indirectly  through  the local  Internet  access
providers  that hold a Type 1 License or a Special Type 2 License,  it will only
be  required  to obtain a General  Type 2  License,  in  general.  We are in the
process of applying for a Special Type 2 License.

 Regulatory Assessment of Other Markets

     Europe,  excluding  European  Union  member  countries.  Telecommunications
services are liberalized in varying  degrees in European  countries that are not
European Union member countries. As a matter of practice, Switzerland and Norway
conform  their  regulatory  frameworks  to the  European  Union model and we are
authorized to provide services to Bridge and third parties in both countries. By
contrast,  in Hungary, upon filing the necessary  notification,  a foreign owned
subsidiary may provide limited data networking  services to a defined group and,
upon receipt of necessary  licenses,  may provide Internet access  services.  In
Poland,  however,  minimum local ownership requirements limit greatly the extent
to which data networking or Internet access services may be provided.

     Asia,  excluding  Japan.  Regulatory  regimes  vary  greatly  in  character
throughout  Asia.  At the  liberalized  end  of the  range,  countries  such  as
Australia and New Zealand have liberalized  policies that require no licenses to
provide data  networking and Internet  access  services and we are authorized to
provide services to Bridge and third parties in both countries. Other countries,
such as Taiwan, are open to competition, but require service providers to comply
with extensive licensing procedures,  which we are in the process of processing.
At the more restrictive end,  countries such as Indonesia and India require some
minimum  level of domestic  ownership  in order to provide data  networking  and
Internet access services to persons other than Bridge.

                                  RISK FACTORS

     In connection  with the safe harbor  provisions  of the Private  Securities
Litigation  Reform  Act of 1995,  set  forth  below  are  cautionary  statements
identifying  important  factors  that could  cause our actual  results to differ
materially from those projected in any forward-looking  statements made by or on
behalf  of  us,   whether   oral  or  written.   We  wish  to  ensure  that  any
forward-looking  statements are accompanied by meaningful  cautionary statements
in order to maximize to the fullest extent  possible the projections of the safe
harbor  established  in the Private  Securities  Litigation  Reform Act of 1995.
Accordingly,  any such  statements  are qualified in their entirety by reference
to, and are accompanied by, the following important factors that could cause our
actual results to differ materially from those projected in our  forward-looking
statements.


RISKS RELATED TO OUR BUSINESS


A SIGNIFICANT  PORTION OF OUR REVENUES IS EXPECTED TO COME FROM BRIDGE,  AND THE
LOSS OF BRIDGE AS A CUSTOMER  OR REDUCED  DEMAND FROM  BRIDGE  WOULD  MATERIALLY
ADVERSELY AFFECT OUR BUSINESS.

     We have  entered  into a network  services  agreement  with Bridge  whereby
Bridge became our largest customer. Under the network services agreement, Bridge
committed  to purchase at least of $105 million of network  services  from us in
2000.  Assuming we had received these minimum revenues for the first year of the
agreement in 1999,  Bridge would have represented  approximately 83% of our 1999
revenues.  The network services  agreement with Bridge could be terminated prior
to its term if we default in our performance under this agreement,  including if
we fail to meet our service  level  commitments,  or Bridge is unable to perform
its  obligations  under the  agreement.  The loss of Bridge  as a  customer,  or
reduced demand from Bridge,  would materially  reduce our expected revenues and,
consequently, would have a material adverse effect on our business.


BRIDGE IS HIGHLY  LEVERAGED,  HAS HAD  SIGNIFICANT  NET LOSSES AND NEGATIVE CASH
FLOW TO DATE AND IS REQUIRED TO MAKE AN $88 MILLION  DEBT  REPAYMENT BY JUNE 30,
2000.  IF BRIDGE IS UNABLE TO MEET ITS  FINANCIAL  COMMITMENTS  TO US, WE MAY BE
ADVERSELY AFFECTED.

     We will rely on Bridge to meet its  financial  commitments  to us.  For the
fiscal years ended December 31, 1996, 1997 and 1998, Bridge has informed us that
it had net losses of  approximately  $61 million,  $69 million and $143 million,
respectively.  For the nine months  ended  September  30,  1999,  Bridge had net
losses of approximately  $134 million and had negative cash flows from operating
activities  of  approximately  $76  million.  Bridge  has  informed  us  that it
continued  to use cash in its  operating  activities  for the three months ended
December 31, 1999 and March 31, 2000.

     As of September 30, 1999,  Bridge had $1,240  million of  indebtedness  and
$470  million  of  redeemable  preferred  stock.  Under  the  terms  of its debt
agreements,  Bridge is required to repay approximately $360 million of its total
indebtedness  on or before June 30, 2000. To date, $272 million has been repaid.
Bridge  received   aggregate  proceeds  from  our  initial  public  offering  of
approximately  $177  million  from its sale of our shares,  our  purchase of the
network assets, the payment of a preferential  distribution and the repayment of
a portion of our indebtedness to them. In addition, pursuant to a stock purchase
agreement  dated  February 7, 2000,  Bridge on February 28, 2000,  sold for $150
million in cash to Welsh  Carson  6,250,000  shares of our common  stock held by
Bridge.  The purchase price per share was equal to the initial  public  offering
price per share.  Bridge has informed us that it has used all of these  proceeds
to reduce its  indebtedness.  Of the amounts paid down,  Bridge has subsequently
reborrowed $25 million under a revolving credit agreement.

     We cannot  assure you that Bridge will have  sufficient  sources of capital
to:

   o  meet  its  capital   expenditure,   debt   service  and  working   capital
      requirements,  including its obligations to us under the network  services
      agreement; or

   o  satisfy the requirement under its credit agreement to repay $88 million of
      its indebtedness by June 30, 2000.


                                       22
<PAGE>

     The  failure  by Bridge to meet  these  requirements  could have a material
adverse effect on our operations and the price of our common stock.

THE AUDIT REPORT  ACCOMPANYING  BRIDGE'S 1998 FINANCIAL  STATEMENTS  CONTAINS AN
EXPLANATORY PARAGRAPH REGARDING BRIDGE'S ABILITY TO CONTINUE AS A GOING CONCERN.

     As a result of losses,  working  capital  deficiencies  and other liquidity
issues Bridge's  independent  auditors' report on its 1998 financial  statements
includes an explanatory  paragraph  regarding its ability to continue as a going
concern.

IF THE AMORTIZATION PERIODS FOR BRIDGE'S INTANGIBLES HAD BEEN SHORTER,  BRIDGE'S
LOSSES WOULD HAVE INCREASED.

     At  September  30, 1999,  Bridge's  unamortized  goodwill  and  intangibles
resulting from  acquisitions was  approximately  $863.9 million or approximately
54% of total  assets.  Goodwill is the excess of cost over the fair value of the
net assets of  businesses  acquired.  We cannot assure you that Bridge will ever
realize  the value of such  goodwill.  This  goodwill  is being  amortized  on a
straight-line  basis over 3 to 40 years.  Bridge will  continue to evaluate on a
regular basis whether events or circumstances have occurred that indicate all or
a portion of the carrying  amount of goodwill may no longer be  recoverable,  in
which case an additional  charge to earnings  would become  necessary.  Any such
future  determination  requiring  the  write-off  of a  significant  portion  of
unamortized  goodwill could have a material adverse effect on Bridge's financial
condition or results of operations.  If Bridge had used amortization  periods of
no longer  than ten  years,  the net loss would  have been  $68.7  million,  $86
million,  $180.7  million and $180  million for the periods  ended  December 31,
1996, 1997, 1998 and September 30, 1999, respectively.

BRIDGE MAY BE ENTITLED TO TERMINATE  THE NETWORK  SERVICES  AGREEMENT OR COLLECT
LIQUIDATED DAMAGES IF WE ARE NOT ABLE TO MEET QUALITY OF SERVICE LEVELS.

     Pursuant to the network services agreement with Bridge, we have agreed that
the  network  will  perform  in  accordance  with  specific  quality  of service
standards within 12 months from the date we acquire the network. In the event we
do not meet the required  quality of service levels,  Bridge will be entitled to
credits  and,  in the event of a material  breach of such  quality  of  services
levels, Bridge will be entitled to terminate the network services agreement and,
whether or not the network  service  agreement is terminated,  collect up to $50
million as liquidated damages once during any 36-month period.

OUR LIMITED  HISTORY,  AND THE FACT THAT WE ONLY  RECENTLY  BEGAN  OFFERING DATA
NETWORKING AND COLOCATION  SERVICES,  MAKES IT DIFFICULT FOR YOU TO EVALUATE OUR
PERFORMANCE.

     Although we began  commercial  operations in 1996,  we only recently  began
offering  data  networking  and  colocation  services.  We expect to  generate a
substantial  portion of our  revenues  from these  services  in the  future.  In
addition,  many of our executive officers and key technical  employees joined us
recently,  and we have adopted our business strategies recently.  Because of our
limited  operating  history,  you have very limited operating and financial data
about us upon which to base an evaluation of our  performance  and prospects and
an investment in our common stock.  Therefore,  you should consider and evaluate
our prospects in light of the risks and difficulties  frequently  encountered by
rapidly growing companies,  particularly  companies in the rapidly evolving data
networking, Internet access and colocation markets.

OUR  HISTORICAL  FINANCIAL  INFORMATION  WILL  NOT  BE  COMPARABLE TO OUR FUTURE
FINANCIAL PERFORMANCE.

     In February 2000, we acquired Bridge's Internet protocol network assets and
entered into an agreement to provide data  networking  services to Bridge.  As a
result, our historical  financial  information  included in this report will not
necessarily be comparable to our results of operations,  financial  position and
cash flows in the future.

WE EXPECT TO CONTINUE TO INCUR  SUBSTANTIAL  LOSSES AND HAVE NEGATIVE  OPERATING
CASH FLOW.

     We incurred losses of approximately $14.0 million,  $20.0 million and $46.7
million  in 1997,  1998 and 1999 and had  negative  cash  flows  from  operating
activities of $10.5 million,  $20.6 million and $24.5 million in these years. We
expect to incur  significant  net  losses,  negative  cash  flow from  operating
activities and negative EBITDA at least through 2002.


                                       23
<PAGE>

WE EXPECT OUR OPERATING EXPENSES TO INCREASE SIGNIFICANTLY.

     From the  acquisition  by Bridge of our  company  on April 7, 1999  through
December 31, 1999,  we had a loss of  approximately  $38.6  million and net cash
used in operating  activities of approximately $18.3 million. As of December 31,
1999, our accumulated  deficit was approximately  $38.6 million,  which reflects
only our losses  since Bridge  acquired our company on April 7, 1999.  We expect
our  operating  expenses to increase  significantly,  especially in the areas of
data  communications and operations,  as a result of the acquisition of Bridge's
network  assets,  and sales and marketing,  as we continue to develop and expand
our business.  As a result, we will need to increase our revenues  significantly
to generate cash flow from our operations.


WE WILL INCUR LOSSES FROM THE  OPERATION  OF THE NETWORK TO PROVIDE  SERVICES TO
BRIDGE UNDER THE NETWORK  SERVICES  AGREEMENT UNTIL WE USE THE NETWORK EITHER TO
PROVIDE ADDITIONAL SERVICES TO BRIDGE OR NEW CUSTOMERS.

     Under the network  services  agreement  with  Bridge,  the amount we charge
Bridge for the use of the network as  configured  on the date of the transfer is
based on the cash costs of operating  that network.  As a result,  we will incur
losses from the operation of the network to provide  services to Bridge until we
use the network  either to provide  additional  services to Bridge not currently
covered by the network services  agreement,  such as connecting new customers of
Bridge or adding  additional  connections to existing  customers,  or to provide
services  to new  customers.  We  cannot  guarantee  that  we will  sell  enough
additional services to become profitable.


WE ARE  OBLIGATED  TO PROVIDE  NETWORK  SERVICES TO BRIDGE FOR A PERIOD OF UP TO
FIVE YEARS AFTER THE TERMINATION OF THE NETWORK SERVICES  AGREEMENT AT THE RATES
IN EFFECT AT THE DATE OF THE AGREEMENT'S TERMINATION.

     We are  required to provide  network  services to Bridge  under the network
services  agreement  for  a  period  of up  to  five  years  subsequent  to  the
termination of the  agreement.  These services must be provided to Bridge at the
rates in effect for our third  party  customers  at the date of the  agreement's
termination. If the price to be paid by Bridge is less than the cost incurred by
us to provide the service, such services will be provided at a loss to us.


THE  PURCHASE OF THE  NETWORK  ASSETS  FROM  BRIDGE  RESULTED IN A  PREFERENTIAL
DISTRIBUTION TO BRIDGE.

     Because we recorded the network  assets  purchased  from Bridge at Bridge's
historical  net book  value,  the excess of the  payments to Bridge over the net
book value,  approximately $58 million, was treated for accounting purposes as a
preferential  distribution to Bridge. As a result our  stockholders'  equity has
been reduced and purchasers of our common stock in our initial  public  offering
experienced a dilution in tangible book value per share.


IF WE ARE NOT ABLE TO RAISE ADDITIONAL CAPITAL, WE MAY HAVE TO DELAY SOME OR ALL
OF OUR EXPANSION PLANS.

     As we develop and expand our business,  we will require significant capital
to fund our capital  expenditures,  operating deficits and working capital needs
as well as our debt service  requirements.  We believe  that our existing  cash,
cash  equivalents,  short-term  investments  and anticipated  vendor  financing,
including the net proceeds from the initial public offering,  will be sufficient
to meet our capital  requirements through the end of 2000. We currently estimate
that we will make  approximately  $149 million of capital  expenditures in 2000,
exclusive  of our purchase of the network  assets from Bridge,  and we expect to
make significant  capital  expenditures in the following years. In addition,  we
expect to incur  significant  net  losses,  negative  cash  flow from  operating
activities  and negative  EBITDA at least through 2002.  The actual  amounts and
timing  of our  future  capital  requirements  may vary  significantly  from our
estimates.  Our  capital  needs may exceed our current  expectations  because of
factors  such as  acquisitions  that we may make,  changes in the demand for our
services, regulatory developments, the competitive environment in our markets or
failure to expand our business as expected. In that case, we may need to


                                       24
<PAGE>

seek additional capital sooner than we expect, and such additional financing may
not be  available  on  acceptable  terms or at all.  If we are  unable  to raise
additional  capital when needed,  we may have to delay or abandon some or all of
our  expansion  plans  or  otherwise  forego  market  opportunities.  We do  not
currently have a credit facility from which we could access additional capital.



IF WE ARE NOT RELEASED FROM  REGULATION  UNDER THE BANK HOLDING  COMPANY ACT, WE
WOULD NOT BE ABLE TO EXPAND OUR BUSINESS AS WE EXPECT.


     State  Street   Corporation,   a  bank  holding  company,   currently  owns
approximately  7.7% of the outstanding voting capital stock of Bridge on a fully
diluted basis and approximately 2% of our outstanding common stock. State Street
also has the right to elect one member of Bridge's  board of  directors.  At the
time State Street made its  investment  in Bridge in 1996,  State Street  agreed
with the Federal  Reserve Board to regard Bridge as a subsidiary of State Street
for purposes of the Bank Holding  Company Act, and Bridge agreed to restrict its
activities  and its  investments  to those  permitted  for bank holding  company
subsidiaries under Regulation Y of the Federal Reserve Board. At the time Bridge
acquired us in April 1999,  State Street and Bridge agreed that we also would be
regarded as a bank  holding  company  subsidiary  and subject to the  applicable
restrictions on our activities.  Permitted activities for a bank holding company
subsidiary  include the transmission of data,  provided that no more than 30% of
the revenue generated by a bank holding company subsidiary from that activity is
derived from the transmission of data that is not financial, banking or economic
in nature.  Accordingly,  in connection with Bridge's acquisition of our company
in April 1999, Bridge undertook to ensure that at least 70% of our revenue would
be derived  from the  transmission  of  qualifying  data.  We  believe  that the
services we will provide to Bridge  under the network  services  agreement  will
satisfy this requirement initially.


     In the event State  Street does not comply with its  agreement to cooperate
with us to ensure that,  by the close of business on April 30, 2000,  we will no
longer be subject to the activity and investment  restrictions  of Regulation Y,
our  revenues  from  Bridge  and/or  revenues  from  the  transmission  of other
qualifying  data will need to represent at least 70% of our total revenue.  As a
result, we may not be able to expand our business as currently contemplated.


OUR FAILURE TO MANAGE OUR GROWTH EFFECTIVELY COULD IMPAIR OUR BUSINESS.


     We expect our business to continue to grow rapidly, which may significantly
strain  our  management,  financial,  customer  support,  sales,  marketing  and
administrative  resources,  as well as our network operations and our management
and  billing  systems.  Such  a  strain  on  our  managerial,   operational  and
administrative  capabilities  could adversely affect the quality of our services
and our ability to generate revenues. To manage our growth effectively,  we will
have to further enhance the efficiency of our operational support and other back
office systems, and of our financial systems and controls.  We will also have to
expand,  train and manage our employees and third-party  providers to handle the
increased  volume and complexities of our business.  In addition,  if we fail to
project traffic volume and routing preferences  correctly,  or fail to determine
the appropriate  means of expanding our network,  we could lose customers,  make
inefficient use of our network, and have higher costs and lower profit margins.


OUR  SUBSTANTIAL  ONGOING  RELATIONSHIPS  WITH  BRIDGE  WILL  BE CRITICAL TO OUR
SUCCESS.   IF  BRIDGE  TERMINATES  ANY  OF  THESE  RELATIONSHIPS,  OUR  BUSINESS
PROSPECTS WILL BE IMPAIRED.


     Bridge  provides  to us  many  technical,  administrative  and  operational
services and related support functions, including technical and customer support
service and project management in the procurement and installation of equipment.
Bridge also provides to us additional  administrative and operational  services,
such as payroll and accounting  functions,  benefit management and office space.
If Bridge  unexpectedly  stops providing these services for any reason, we could
face  significant  challenges and costs in assuming these services or finding an
alternative to Bridge.  This could impair our operations,  adversely  affect our
reputation and harm our financial results.


                                       25
<PAGE>

     In addition, we sublease from Bridge some of the network assets that Bridge
currently  leases  from  General  Electric  Capital  Corporation,  or GECC.  The
aggregate amount of our capitalized lease obligations to Bridge is approximately
$22 million.  We do not have a direct relationship with GECC. If Bridge fails to
perform  its  obligations  under its  agreement  with  GECC,  our rights to such
network assets may be impaired.


WE ARE CONTROLLED BY PARTIES WHOSE INTERESTS MAY NOT BE ALIGNED WITH YOURS.

     Bridge  and   investment   partnerships   sponsored  by  Welsh  Carson  own
approximately  49% and 16% of our  outstanding  common stock,  respectively.  In
addition,   Welsh  Carson   partnerships  own   approximately  38%  of  Bridge's
outstanding voting stock.  Consequently,  Bridge and Welsh Carson control us and
are in a position to elect our entire board of directors and control all matters
affecting us. In addition, Welsh Carson may be deemed to be a controlling person
of Bridge.

     Some decisions concerning our operations or financial structure may present
conflicts   of  interest   between   Bridge  and  Welsh  Carson  and  our  other
stockholders.  For example, Bridge or Welsh Carson may make investments in other
entities engaged in the telecommunications  business,  some of which may compete
with us. Also,  Bridge and Welsh Carson are under no  obligation  to bring to us
any investment or business  opportunities of which they are aware, even if these
opportunities are within our scope and objectives.

     We  entered  into a  number  of  agreements  with  Bridge  relating  to the
acquisition of Bridge's global Internet protocol network and to our provision of
global data networking  services to Bridge and Bridge  provides  various support
services to us. Because we were  controlled by Bridge during the  negotiation of
the  agreements,  we cannot assure you that these  agreements  are comparable to
those  that  would  have  been  reached  had the  terms  been  negotiated  on an
arm's-length basis.


WE  DEPEND  ON  KEY  PERSONNEL.  IF  WE  ARE UNABLE TO HIRE AND RETAIN QUALIFIED
PERSONNEL, WE MAY BE UNABLE TO IMPLEMENT OUR BUSINESS STRATEGY EFFECTIVELY.

     Our future  performance  depends to a  significant  degree on the continued
contributions of our management  team, sales force and key technical  personnel.
In  particular,  we depend on Robert  McCormick,  our  Chairman of the Board and
Chief Executive Officer.  Mr. McCormick was appointed Chief Executive Officer in
November  1999. In addition,  our business  plan  contemplates  the  significant
expansion of our sales and marketing  staff.  The industries in which we compete
are characterized by a high level of employee mobility and aggressive recruiting
of  skilled  personnel.  As a  result,  we may have  difficulty  in  hiring  and
retaining  highly  skilled  employees.  Our  future  performance  depends on our
ability to attract, retain and motivate highly skilled employees.


FAILURES IN OUR NETWORK OR WITH THE NETWORK  OPERATIONS CENTER COULD DISRUPT OUR
ABILITY TO PROVIDE OUR DATA NETWORKING, INTERNET ACCESS AND COLOCATION SERVICES,
WHICH COULD HARM OUR BUSINESS AND INCREASE OUR CAPITAL COSTS.

     Our ability to  successfully  implement  our business plan depends upon our
ability to provide high quality, reliable services. Interruptions in our ability
to provide our data networking,  Internet access and colocation  services to our
customers  could adversely  affect our business and  reputation.  Our operations
depend  upon our ability to protect our  equipment  and network  infrastructure,
including   connections  to  our  communications   transmission,   or  backbone,
providers,  and our customers'  data and equipment,  against damage from natural
disasters, as well as power loss, telecommunications failure and similar events.
The occurrence of a natural disaster or other unanticipated problem could result
in interruptions in the services we provide to our customers and could seriously
harm our business and business prospects.


WE ARE HIGHLY DEPENDENT ON OUR SUPPLIERS, AND ANY INTERRUPTIONS COULD IMPAIR OUR
SERVICE TO OUR CUSTOMERS.

     If we are unable to obtain required  products or services from  third-party
suppliers  on a timely  basis  and at an  acceptable  cost,  we may be unable to
provide  our data  networking,  internet  access and  colocation  services  on a
competitive and timely basis. We are dependent on other companies to supply


                                       26
<PAGE>

various key  components  of our  infrastructure,  including  network  equipment,
backbone connectivity,  the connections from our customers to our network, which
we call local access, and connection to other Internet network providers. If our
suppliers  fail to provide  products  or  services  on a timely  basis and at an
acceptable cost, we may be unable to meet our customer service  commitments and,
as a result, we may experience increased costs or loss of revenue.


IF WE ARE UNABLE TO EXPAND OUR NETWORK AS  EXPECTED,  OUR RESULTS OF  OPERATIONS
WOULD BE ADVERSELY AFFECTED.

     Our success will depend on our ability to continue to expand our network on
a timely,  cost-effective  basis. A number of factors could hinder the expansion
of our network.  These factors  include cost  overruns,  the  unavailability  of
appropriate facilities,  communications capacity or additional capital, strikes,
shortages,  delays in obtaining  governmental  or other  third-party  approvals,
natural disasters and other casualties, and other events that we cannot foresee.
In addition,  expanding or enhancing our network,  including through hardware or
software upgrades,  could result in unexpected  interruptions of services to our
customers.


IF OUR ESTIMATES  REGARDING OUR TRAFFIC LEVELS ARE NOT CORRECT,  WE MAY HAVE TOO
MUCH OR TOO LITTLE CAPACITY.

     We rely on other carriers to provide several data transmission services. We
generally lease data transmission  capacity before we have secured customers and
our leased  capacity  costs are typically  fixed monthly  payments  based on the
capacity made  available to us. Our failure to correctly  estimate  transmission
capacity  could  increase  the  cost or  reduce  the  quality  of our  services.
Underestimation  of  traffic  levels  could  lead  to a  shortage  of  capacity,
requiring us to lease more capacity, which may be at unfavorable rates, or could
lead to a lower quality of service  because of increased  data loss and latency.
Overestimation of traffic levels, because our traffic volumes decrease or do not
grow as expected, would result in idle capacity, thereby increasing our per-unit
costs.


WE HAVE EXPERIENCED  CUSTOMER  TURNOVER IN THE PAST AND MAY CONTINUE TO DO SO IN
THE  FUTURE.   IF  WE  CONTINUE  TO  EXPERIENCE   CUSTOMER  TURNOVER  WITHOUT  A
CORRESPONDING GROWTH IN NEW CUSTOMERS, OUR BUSINESS MAY BE ADVERSELY AFFECTED.

     Customer  turnover in the Internet access  business is high.  Customer loss
results in loss of future  revenue from  subscribers  who  discontinue or reduce
their  services.  Customer  loss occurs for several  reasons,  such as voluntary
disconnection  by  subscribers  who choose to switch to a competing  service and
termination by Internet access providers for nonpayment of bills or abuse of the
network. We have experienced customer turnover in the past and as our subscriber
base grows and the  industry  matures,  our  customer  loss may continue or even
increase. If, in the future, we were to lose a large number of customers without
signing  contracts with new  customers,  there could be an adverse impact on our
business.


OUR  BRAND  IS NOT AS WELL KNOWN AS SOME OF OUR COMPETITORS'. FAILURE TO DEVELOP
BRAND RECOGNITION COULD HURT OUR ABILITY TO COMPETE EFFECTIVELY.

     We need to  strengthen  our brand  awareness to realize our  strategic  and
financial  objectives.  Many of our  competitors  have  well-established  brands
associated with the provision of data networking, Internet access and colocation
services. The promotion and enhancement of our brand also will depend in part on
our success in continuing to provide high quality  Internet  access services and
in providing high quality data  networking and  colocation  services.  We cannot
assure you that we will be able to maintain or achieve these levels of quality.


ANY BREACH OF SECURITY OF OUR NETWORK COULD NEGATIVELY IMPACT OUR BUSINESS.

     Our network may be vulnerable to unauthorized access,  computer viruses and
other  disruptive  problems caused by customers,  employees or others.  Computer
viruses,  unauthorized  access  or  other  disruptive  problems  could  lead  to
interruptions, delays or cessation of service to our customers and these


                                       27
<PAGE>

customers' end users.  Unauthorized access also could potentially jeopardize the
security  of  confidential  information  stored in the  computer  systems of our
customers,  which might result in our liability to our customers, and also might
deter potential customers.  We may be unable to implement security measures in a
timely manner or, if and when implemented,  these measures could be circumvented
as a result of accidental or intentional actions. In the past, security measures
employed by others have been circumvented by third parties. Eliminating computer
viruses and  alleviating  other  security  problems  may require  interruptions,
delays or cessation of service to our customers and these  customers' end users.
Any breach of  security on our  network  may result in a loss of  customers  and
damage to our reputation.


WE MAY NOT BE ABLE TO MEET THE OBLIGATIONS UNDER OUR SERVICE LEVEL AGREEMENTS.

     We have service level agreements with many of our Internet access customers
in which we provide  various  guarantees  regarding  our levels of  service.  In
addition,  the network services agreement with Bridge requires levels of service
and we offer service level agreements to other data networking customers.  If we
fail to  provide  the  levels  of  service  required  by these  agreements,  our
customers  may be entitled to terminate  their  relationship  with us or receive
service credits for their accounts.  If Bridge or a significant  number of other
customers  become  entitled to exercise,  and do  exercise,  these  rights,  our
revenues could be materially reduced.


WE MAY MAKE  ACQUISITIONS  OR ENTER INTO JOINT VENTURES OR STRATEGIC  ALLIANCES,
EACH OF WHICH IS ACCOMPANIED BY INHERENT RISKS.

     If appropriate  opportunities present themselves,  we may make acquisitions
or investments  or enter into joint  ventures or strategic  alliances with other
companies. Risks commonly encountered in such transactions include:

     o the  difficulty  of  assimilating  the  operations  and  personnel of the
combined companies;

   o  the  risk  that we may not be able to  integrate  the  acquired  services,
      products  or  technologies  with  our  current   services,   products  and
      technologies;

     o the potential disruption of our ongoing business;

     o the inability to retain key technical and managerial personnel;

   o the  inability  of  management  to  maximize  our  financial  and strategic
      position through the successful integration of acquired businesses;

   o  increases  in  reported  losses  as a result  of  charges  for  in-process
      research and development and amortization of goodwill and other intangible
      assets;

     o adverse impact on our annual effective tax rate;

     o difficulty in maintaining controls, procedures and policies; and

   o the  impairment  of  relationships  with employees, suppliers and customers
      as a result of any integration.


WE FACE  REGULATORY  RESTRICTIONS  IN SIGNIFICANT  NUMBER OF COUNTRIES THAT HAVE
DELAYED AND MAY PREVENT US FROM ACQUIRING OR OPERATING  BRIDGE ASSETS LOCATED IN
THESE COUNTRIES.  THESE ASSETS REPRESENT  APPROXIMATELY 4% OF THE NET BOOK VALUE
OF THE ASSETS ACQUIRED FROM BRIDGE.

     Regulatory restrictions in the following ten countries currently prevent us
from  acquiring the Bridge  network  assets  located in these  countries.  These
countries are:

     o Europe--Poland;

     o Africa--South Africa;

     o Middle  East--Bahrain, Kuwait, Saudi Arabia and the United Arab Emirates;


     o Asia Pacific--China, India, Macau and Thailand; and

                                       28
<PAGE>

     o The Americas/Caribbean--none.

     Regulations  in the  following  eight  countries  permit us to acquire  the
Bridge  network  assets  located  in  these  countries  upon  obtaining   proper
regulatory  authorization,  which  we are  in the  process  of  pursuing.  These
countries are:

     o Europe--Greece, Ireland and Hungary;

     o Africa--none;

     o Middle East--none;

     o Asia Pacific--Malaysia and Taiwan; and

     o The Americas/Caribbean--Bahamas, Mexico and Venezuela.

     We will be obligated  to acquire the network  assets from Bridge in each of
these 17 countries at book value once we have  received the required  approvals.
We  cannot  assure  you,  however,  that we will be  able  to  comply  with  the
regulatory and other requirements necessary to allow us to acquire these assets.
In all  countries  where we have  received  regulatory  approval  to acquire and
operate the Bridge assets,  we will be permitted to deliver network  services to
Bridge, but not necessarily data networking services to third parties. Providing
services  to  third   parties  in  these   countries   may  require  a  separate
authorization or may not be permitted under current regulations.


NUMEROUS FACTORS MAY CAUSE  FLUCTUATIONS IN OUR QUARTERLY REVENUES AND OPERATING
RESULTS, AS WELL AS IMPACT OUR LONG-TERM VIABILITY.

     Our quarterly  revenues and operating  results have  fluctuated in the past
and are likely to fluctuate  significantly from quarter to quarter in the future
due to a number of factors. These factors include the following:

   o demand  for  and  market acceptance of our data networking, Internet access
      and colocation services;

     o the fixed nature of approximately 75% of our costs;

   o the   timing   and  magnitude  of  capital  expenditures,  including  costs
      relating to the expansion of operations;

     o increasing sales, marketing and other operating expenses;

     o the  compensation of our sales personnel based on achievement of periodic
sales quotas;

     o our ability to generate revenues for our services;

     o changes  in  our  revenue  mix between usage-based and fixed rate pricing
plans; and

     o fluctuations in the duration of the sales cycle for our services.

     Other factors, which are beyond our control, may also affect us, including:

   o  conditions specific to the data networking, Internet access and colocation
      services industries, as well as general economic factors;

     o the  announcement  or  introduction  of  new  or enhanced services by our
competitors;

     o our  ability  to  obtain,  and the pricing for, local access connections;
and,

     o changes in the prices we pay Internet backbone providers.

     Accordingly, we believe that period-to-period comparisons of our results of
operations  are not  meaningful  and should not be relied upon as indications of
future  performance.  In  addition,  these  factors  may  impact  our  long-term
viability.


                                       29
<PAGE>

     It is possible that in some future  periods our results of  operations  may
fall below the expectations of investors. In this event, the price of our common
stock may fall.  You should not rely on  quarter-to-quarter  comparisons  of our
results of operations as an indication of future performance.


WE MAY BE LIABLE FOR THE MATERIAL  THAT CONTENT  PROVIDERS  DISTRIBUTE  OVER OUR
NETWORK.

     The  law  relating  to the  liability  of  private  network  operators  for
information  carried on or  disseminated  through  their  networks is  currently
unsettled.  We may  become  subject  to legal  claims  relating  to the  content
disseminated  on our network.  For example,  lawsuits may be brought  against us
claiming that  material on our network on which one of our customers  relied was
inaccurate.  Claims could also involve  matters such as defamation,  invasion of
privacy and copyright infringement. Content providers operating private networks
have been sued in the past,  sometimes  successfully,  based on the  content  of
material.  If we need to take costly  measures  to reduce our  exposure to these
risks,  or are required to defend  ourselves  against such claims,  our business
could be adversely affected.


RISKS RELATED TO OUR INDUSTRY


DATA  NETWORKING,  INTERNET  ACCESS AND COLOCATION  SERVICES ARE NEW AND RAPIDLY
GROWING MARKETS, BUT THIS GROWTH MAY NOT CONTINUE.

     According to International Data Corporation,  an independent research firm,
the market for data networking  services has been growing  rapidly.  If the data
networking  services market does not grow as expected,  or our anticipated share
of that  market  does not grow as  expected,  our  revenues  could be less  than
expected.

     In addition,  the market for Internet access and related services,  such as
colocation services,  is in an early stage of growth. As a consequence,  current
and future  competitors are likely to introduce  competing  services,  and it is
difficult  to predict  the rate at which the market will grow or at which new or
increased  competition will result in market  saturation.  We face the risk that
the market for high performance Internet access and related services may fail to
develop or may develop more slowly than we expect,  or that our services may not
achieve  widespread market acceptance.  Furthermore,  we may be unable to market
and sell our services  successfully and cost-effectively to a sufficiently large
number of customers.


WIDESPREAD COMMERCIAL USE OF THE INTERNET MAY BE HAMPERED BY POOR PERFORMANCE.

     Despite  growing  interest in the varied  commercial  uses of the Internet,
many businesses have been deterred from purchasing  Internet access services for
a number of reasons,  including  inconsistent or unreliable  quality of service,
lack of availability of cost-effective,  high-speed options, a limited number of
local  access  points for  corporate  users,  inability  to  integrate  business
applications  on the  Internet,  the need to deal with  multiple and  frequently
incompatible  vendors and a lack of tools to simplify  Internet  access and use.
Capacity  constraints  caused by growth in the use of the Internet  may, if left
unresolved,  impede further development of the Internet to the extent that users
experience delays, transmission errors and other difficulties.


GROWTH IN INTERNET ACCESS BUSINESS MAY BE HAMPERED BY SOME COMPANIES' RELUCTANCE
TO ADOPT INTERNET STRATEGIES FOR COMMERCE AND COMMUNICATION.

     The  adoption of  Internet  strategies  for  commerce  and  communications,
particularly by those individuals and enterprises that have historically  relied
upon  alternative  means of commerce and  communication,  generally  requires an
understanding and acceptance of a new way of conducting  business and exchanging
information.  In particular,  enterprises that have already invested substantial
resources in other means of conducting  commerce and exchanging  information may
be  particularly  reluctant or slow to adopt a new strategy  that may make their
existing  personnel and infrastructure  obsolete.  The failure of the market for
business-related  Internet  services to further develop could cause our revenues
to grow more  slowly  than  anticipated  and reduce the demand for our  Internet
access and colocation services.


                                       30
<PAGE>

OUR  ABILITY TO COMPETE  FOR  INTERNET  ACCESS  BUSINESS  MAY BE WEAKENED IF THE
PROBLEMS OF INTERNET CONGESTION, TRANSMISSION DELAYS AND DATA LOSS IS RESOLVED.


     If the  Internet  becomes  subject to a form of central  management,  or if
Internet  backbone  providers  establish  an  economic  settlement   arrangement
regarding  the  exchange  of traffic  between  data  networks,  the  problems of
congestion,  latency and data loss  addressed  by our Internet  access  services
could be largely resolved and our ability to compete for business in this market
could be adversely affected.


THE MARKETS  FOR DATA  NETWORKING,  INTERNET  ACCESS AND  COLOCATION  ARE HIGHLY
COMPETITIVE, AND WE MAY NOT BE ABLE TO COMPETE EFFECTIVELY.

     The markets for data  networking,  Internet access and colocation  services
are extremely  competitive,  and there are few significant barriers to entry. We
expect that  competition  will intensify in the future,  and we may not have the
financial  resources,  technical  expertise,  sales and  marketing  abilities or
support  capabilities  to compete  successfully  in these  markets.  Many of our
existing Internet access data networking and colocation competitors have greater
market   presence,   engineering  and  marketing   capabilities  and  financial,
technological  and personnel  resources than we do. As a result,  as compared to
us, our competitors may:

   o develop  and  expand their networking infrastructures and service offerings
      more efficiently or more quickly;

     o adapt  more  rapidly  to  new  or  emerging  technologies  and changes in
customer requirements;

     o take  advantage of acquisitions and other opportunities more effectively;


     o develop  products  and services that are superior to ours or have greater
market acceptance;

   o  adopt more aggressive pricing policies and devote greater resources to the
      promotion, marketing, sale, research and development of their products and
      services;

     o make more attractive offers to our existing and potential employees;

     o establish  cooperative  relationships  with  each  other  or  with  third
parties; and

   o  more effectively take advantage of existing  relationships  with customers
      or exploit a more  widely  recognized  brand name to market and sell their
      services.

     Our competitors include:

   o  backbone  providers that may provide us connectivity  services,  including
      AT&T, Cable & Wireless plc, GTE Internetworking, ICG Communications, Inc.,
      Sprint Corporation and UUNET, an MCI Worldcom company;

   o  global,  national and  regional  telecommunications  companies,  including
      regional Bell  operating  companies  and providers of satellite  bandwidth
      capacity; and


     o global, national and regional Internet service providers.


     We expect that new  competitors  will enter the data  networking,  Internet
access and  colocation  markets.  Such new  competitors  could include  computer
hardware, software, media and other technology and telecommunications companies,
as well as  satellite  and  cable  companies.  A  number  of  telecommunications
companies and online service providers  currently offer, or have announced plans
to offer or expand, their data networking services. Further, the ability of some
of these potential  competitors to bundle other services and products with their
data  networking  services  could place us at a  competitive  disadvantage.  For
example,  Reuters Group plc, a news and financial information  distributor,  and
Equant N.V., an international  telecommunications  provider,  recently announced
that they intend to form a joint venture for the purposes of offering IP network
services access to the financial services  industry.  Various companies are also
exploring the possibility of providing,  or are currently providing,  high-speed
data services using alternative delivery methods, including the cable television
infrastructure, direct broadcast


                                       31
<PAGE>

satellites,  all optical networks,  wireless cable and wireless local access. In
addition,   Internet   backbone   providers   may  benefit  from   technological
developments,  such as improved router technology, that will enhance the quality
of their services.


OUR FAILURE TO ACHIEVE  DESIRED PRICE LEVELS COULD IMPACT OUR ABILITY TO ACHIEVE
PROFITABILITY OR POSITIVE CASH FLOW.


     We expect  competition  and other  factors  to  continue  to cause  pricing
pressure in the markets we serve.  Prices for data  networking,  Internet access
and colocation  services have decreased  significantly  in recent years,  and we
expect significant price declines in the future. In addition,  by bundling their
services and reducing  the overall  cost of their  services,  telecommunications
companies  that  compete with us may be able to provide  customers  with reduced
communications  costs in connection with their data networking,  Internet access
or colocation services, thereby significantly increasing pricing pressure on us.
We may not be able to offset the effects of any such price  reductions even with
an  increase  in the number of our  customers,  higher  revenues  from  enhanced
services,  cost reductions or otherwise.  In addition,  we believe that the data
networking,  Internet access and colocation industries are likely to continue to
encounter   consolidation  in  the  future.   Increased  price   competition  or
consolidation  in these  markets  could  result in erosion of our  revenues  and
operating margins and could prevent us from becoming profitable.


NEW TECHNOLOGIES COULD DISPLACE OUR SERVICES OR RENDER THEM OBSOLETE.


     New  technologies  or industry  standards  have the potential to replace or
provide lower cost alternatives to our Internet access services, data networking
and  colocation  services.  The  adoption of such new  technologies  or industry
standards  could render these services  obsolete or  unmarketable.  For example,
these  services rely on the continued  widespread  commercial  use of the set of
protocols,  services and  applications  for linking  computers known as Internet
protocol.  Alternative sets of protocols,  services and applications for linking
computers  could  emerge and become  widely  adopted.  Improvements  in Internet
protocol  could emerge that would allow for the assignment of priorities to data
packets in order to ensure their  delivery in the manner  customers  prefer,  as
well as other  improvements,  which could  eliminate  one  advantage  of the ATM
architecture  of our  network.  We  cannot  guarantee  that  we  will be able to
identify  new  service  opportunities  successfully  and  develop  and bring new
products and services to market in a timely and  cost-effective  manner, or that
products,  software  and services or  technologies  developed by others will not
render our current and future services non-competitive or obsolete. In addition,
we cannot  assure you that our  current  and  future  services  will  achieve or
sustain market  acceptance or be able to address  effectively the  compatibility
and  interoperability  issues  raised by  technological  changes or new industry
standards. If we fail to anticipate the emergence of, or obtain access to, a new
technology or industry standard,  we may incur increased costs if we seek to use
those  technologies and standards or our competitors that use such  technologies
and standards may use them more cost-effectively than we do.


THE DATA NETWORKING AND INTERNET ACCESS  INDUSTRIES ARE HIGHLY REGULATED IN MANY
OF THE COUNTRIES IN WHICH WE PLAN TO PROVIDE SERVICES,  WHICH COULD RESTRICT OUR
ABILITY TO CONDUCT BUSINESS INTERNATIONALLY.


     We  are  subject  to  varying   degrees  of   regulation  in  each  of  the
jurisdictions  in which we provide  services.  Local laws and  regulations,  and
their   interpretation  and  enforcement,   differ   significantly  among  those
jurisdictions.  Future regulatory,  judicial and legislative  changes may have a
material  adverse  effect on our  ability to  deliver  services  within  various
jurisdictions.


     National  regulatory  frameworks  that are consistent with the policies and
requirements  of the World Trade  Organization  have only recently  been, or are
still being, put in place in many countries outside the U.S. and European Union.
These  nations  are in the  early  stages of  providing  for and  adapting  to a
liberalized  telecommunications  market. As a result,  in these markets,  we may
encounter  more  protracted  and  difficult  procedures  to obtain  licenses and
negotiate interconnection agreements.


                                       32
<PAGE>

     Our   operations  are  dependent  on  licenses  and   authorizations   from
governmental  authorities  in each  foreign  jurisdiction  in  which  we plan to
operate.  These  licenses and  authorizations  generally  will  contain  clauses
pursuant to which we may be fined or our license may be revoked. Such revocation
may be on short notice,  at times as short as 30 days' written  notice to us. We
may not be able to obtain or retain the licenses necessary for our operations.


ADOPTION OR  MODIFICATION  OF  GOVERNMENT  REGULATIONS  RELATING TO THE INTERNET
COULD HARM OUR BUSINESS.

     There  is  currently  only a small  body of laws and  regulations  directly
applicable to access to or commerce on the Internet. However, existing laws have
been applied to Internet transactions in a number of cases. Moreover, due to the
increasing popularity and use of the Internet, international, national, federal,
state and local  governments  may adopt  laws and  regulations  that  affect the
Internet.  The  nature of any new laws and  regulations  and the manner in which
existing and new laws and  regulations may be interpreted and enforced cannot be
predicted  accurately.  The  adoption  of any future laws or  regulations  might
decrease the growth of the Internet,  decrease  demand for our services,  impose
taxes or other costly technical  requirements or otherwise  increase the cost of
doing  business  on the  Internet or in some other  manner have a  significantly
harmful  effect on us or our  customers.  The U.S.  government  also may seek to
regulate some segments of our activities as it has with basic telecommunications
services. Moreover, the applicability to the Internet of existing laws governing
intellectual property ownership and infringement,  copyright,  trademark,  trade
secret,  obscenity,  libel,  employment,  personal  privacy and other  issues is
uncertain and developing.  We cannot predict accurately the impact, if any, that
future laws and  regulations or changes in laws and  regulations may have on our
business.


RISKS RELATED TO OUR COMMON STOCK


A SIGNIFICANT NUMBER OF OUR SHARES ARE ELIGIBLE FOR RESALE AND BRIDGE INTENDS TO
SELL ADDITIONAL SHARES OF OUR COMMON STOCK IN THE FUTURE.  THIS COULD REDUCE OUR
STOCK PRICE AND IMPAIR OUR ABILITY TO RAISE FUNDS IN NEW STOCK OFFERINGS.

     Immediately  after the  completion of our initial public  offering,  we had
92,883,340 shares of common stock outstanding and available for resale beginning
at various points of time in the future.  Sales of substantial amounts of shares
of our common stock in the public market after this offering,  or the perception
that those sales will occur, could cause the market price of our common stock to
decline. Those sales also might make it more difficult for us to sell equity and
equity-related  securities  in the  future  at a time  and at a  price  that  we
consider appropriate. In particular,  Bridge has indicated to us that it intends
in the  future to sell a portion of its  shares of our  common  stock  which may
include sales in the open market or in private  placements or sales to strategic
investors.


OUR  CERTIFICATE OF  INCORPORATION,  BYLAWS AND DELAWARE LAW CONTAIN  PROVISIONS
THAT COULD DISCOURAGE A TAKEOVER.

     Our certificate of incorporation and Delaware law contain  provisions which
may make it more difficult for a third party to acquire us, including provisions
that give the board of directors the power to issue shares of preferred stock.

     We have also  chosen to be subject to Section 203 of the  Delaware  General
Corporation  Law,  which  prevents a stockholder of more than 15% of a company's
voting stock from entering into  business  combinations  set forth under Section
203 with that company.


ITEM 2. PROPERTIES.

     Our  executive  offices  are  located in Reston,  Virginia  and  consist of
approximately 10,500 square feet that are leased under an agreement that expires
in 2004. We have recently entered into a ten and a half-year lease for an 80,000
square foot  facility in Herndon,  Virginia to house our  executive  management,
sales and marketing  personnel and our  Washington,  D.C. data center.  We lease
facilities  for  our  sales  offices  and  network  equipment  in  a  number  of
metropolitan areas and specific cities. We also


                                       33
<PAGE>

lease approximately  10,000 square feet from Bridge in St. Louis,  Missouri.  We
believe  that our existing  facilities,  including  the  additional  space,  are
adequate for our current needs and that suitable additional or alternative space
will be available in the future on commercially reasonable terms as needed.


ITEM 3. LEGAL PROCEEDINGS

     From time to time,  we may be  involved  in  litigation  relating to claims
arising out of our ordinary course of business. We are not currently involved in
any material legal proceedings.


ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

     On December 7, 1999, stockholders holding at least a majority of our common
stock  consented  in  writing to an  amendment  of our 1999  stock  option  plan
providing for an increase in the number of shares of common stock  available for
issuance under the plan.


                                       34
<PAGE>

                                     PART II


ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.


(A)(1) MARKET PRICE OF COMMON STOCK.

     Our common stock,  $.01 par value per share,  has been quoted on the Nasdaq
National  Market under the symbol  "SVVS" since our initial  public  offering on
February  15,  2000.  During the  preceding  two years there was no  established
trading  market for our shares of common  stock.  There are currently 411 record
holders of our common stock.

     We have not  declared or paid any cash  dividends on our common stock since
our inception. We do not intend to pay cash dividends on our common stock in the
foreseeable  future.  We  anticipate  we will retain any earnings for use in our
operations and the expansion of our business.


(A)(2) RECENT SALES OF UNREGISTERED SECURITIES

     Between  January 1, 1999 and  December  31,  1999,  we  granted  options to
purchase  3,937,868  shares  of  our  common  stock  to a  total  of  200 of our
employees,  each at an exercise price of $.50 per share. In that same period, we
granted options to purchase  4,139,000  shares of our common stock to a total of
185  employees of Bridge,  each at an exercise  price of $.50 per share.  All of
these  options were granted  pursuant to our stock option plan. In October 1999,
we granted to our  employees  the right to convert  options to purchase  236,882
shares of common stock of Bridge into options to purchase  236,882 shares of our
common stock at an exercise  price of $0.50 per share.  During  fiscal 1999,  we
issued  5,232,289  shares  pursuant  to the  exercise  of stock  options  by our
employees and employees of Bridge for an aggregate exercise price of $2,616,145.
These  issuances  were effected in reliance on the exemption  from  registration
provided by Rule 701  promulgated  under Section 3(b) of the  Securities  Act of
1933 and were effected without the use of an underwriter.


(B)   USE OF PROCEEDS

     The  Registration  Statement  on Form  S-1 (the  "Registration  Statement")
relating to the initial public offering of our common stock (File No. 333-90881)
was declared  effective by the SEC on February 14, 2000. The offering  commenced
on February 15, 2000 and terminated when all of the shares were sold on February
18, 2000. The managing underwriters for the initial public offering were Merrill
Lynch, Pierce,  Fenner & Smith Incorporated,  Morgan Stanley & Co. Incorporated,
Bear Stearns & Co. Inc.,  Banc of America  Securities LLC and CIBC World Markets
Corp. In the initial  public  offering,  a total of 17,000,000  shares of common
stock were registered. We sold an aggregate of 14,875,000 shares of common stock
pursuant to the Registration  Statement.  Bridge Information Systems,  Inc., the
selling  stockholder,  sold an  aggregate  of  2,125,000  shares of common stock
pursuant to the Registration Statement. The initial public offering price of the
shares was $24.00 per share.  Underwriting  discounts  and  commissions  for the
shares sold in the  initial  public  offering by us and the selling  stockholder
totaled  $21.4  million  and  $3.1  million,   respectively.   After   deducting
underwriting  discounts and commissions  and other expenses,  we and the selling
stockholder received  approximately $333 million and $48 million,  respectively,
in net  proceeds  from the  initial  public  offering.  Of the $333  million  we
received, we used approximately $121 million to purchase assets from Bridge.

     There has been no material change to the information previously provided in
the Registration  Statement relating to expenses incurred in connection with the
offering  and the use of proceeds  from the  offering.  None of our  expenses in
connection  with the offering  were paid directly or indirectly to our directors
or officers or their associates,  or to persons owning 10% or more of our common
stock or other affiliates of our company.


ITEM  6. SELECTED  CONSOLIDATED  FINANCIAL  AND  OPERATIONAL  DATA  (DOLLARS  IN
       THOUSANDS, EXCEPT PER SHARE DATA).

     The following  information should be read in conjunction with "Management's
Discussion  and  Analysis of  Financial  Condition  and Results of  Operations",
"Business", and our consolidated financial statements and related notes included
elsewhere in this report. We derived the selected historical


                                       35
<PAGE>

consolidated  financial  data  presented  below  from our  audited  consolidated
financial  statements.  Our consolidated  financial statements as of and for the
years ended  December 31, 1996, and 1997 have been audited by Ernst & Young LLP,
independent  auditors.  Our consolidated  financial statements as of and for the
periods  since then have been  audited by  Deloitte  & Touche  LLP,  independent
auditors. We began commercial operations in 1996.

     On April 7, 1999,  Bridge acquired all our equity  securities and accounted
for this acquisition as a purchase  transaction.  Since the purchase transaction
resulted in our company becoming a wholly owned subsidiary of Bridge,  SEC rules
required us to establish a new basis of accounting for the purchased  assets and
liabilities.  The accounting for the purchase transaction has been "pushed down"
to the financial  statements of SAVVIS.  Therefore,  the purchase price has been
allocated to the underlying  assets  purchased and liabilities  assumed based on
the  estimated  fair  market  values  of these  assets  and  liabilities  at the
acquisition  date.  As a result of the  application  of fair  value  accounting,
intangibles, goodwill, other liabilities and stockholders' equity were increased
in the SAVVIS consolidated balance sheet. The consolidated balance sheet data as
of December  31, 1999 and  consolidated  statement  of  operations  data for the
period from April 7, 1999 through  December 31, 1999 reflect our  acquisition by
Bridge and are labeled  "Successor." The financial data for the periods prior to
the acquisition are labeled "Predecessor."

     On September 10, 1999, Bridge sold in a private placement approximately 25%
of its equity ownership in SAVVIS to existing  shareholders of Bridge,  at which
time Welsh Carson  purchased  from Bridge a 12% interest in SAVVIS.  On February
28, 2000, Bridge completed the sale of an additional  6,250,000 shares of SAVVIS
common stock to Welsh Carson at $24 per share, for a total cash consideration of
$150  million.  Bridge  and Welsh  Carson now own  approximately  49% and 16% of
SAVVIS common stock, respectively.

     We  calculate   EBITDA  as  earnings   (loss)   before   depreciation   and
amortization,  interest income and expense and income tax expense (benefit).  We
have included information concerning EBITDA because our management believes that
in our  industry  such  information  is a relevant  measurement  of a  company's
financial performance and liquidity. EBITDA is not determined in accordance with
generally  accepted  accounting  principles,  is not  indicative of cash used by
operating  activities  and  should  not  be  considered  in  isolation  or as an
alternative  to, or more  meaningful  than,  measures of  operating  performance
determined  in  accordance  with  generally  accepted   accounting   principles.
Additionally,  our  calculation  of  EBITDA  may  not be comparable to similarly
titled measures of other companies, as other companies may not calculate it in a
similar manner.

ITEM  7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
   OF OPERATIONS.

     You should read the following  discussion  together  with our  consolidated
financial  statements and the related notes to those  financial  statements that
are included in Part II, Item 8 of this Form 10-K, beginning on page F-1 of this
report.


OVERVIEW


     We are a rapidly growing provider of high quality,  high performance global
data networking and  Internet-related  services to medium and large  businesses,
multinational  corporations  and  Internet  service  providers.  To provide  our
Internet  access  services,  we  use  the  SAVVIS  ProActiveSM  Network,  a data
communications  network that uses our eight  PrivateNAPsSM  and our  proprietary
routing  policies to reduce data loss and enhance  performance  by avoiding  the
congested public access points on the Internet.


     We began commercial  operations in 1996,  offering Internet access services
to local and regional  Internet service  providers.  Our customer base has grown
from 15 customers at the end of 1996 to approximately 1,150 presently.


     On March 4, 1998, we acquired Interconnected  Associates,  Inc., a regional
Internet  service  provider  serving  approximately  170  customers  in Seattle,
Washington and Portland,  Oregon,  for $750,000 in cash and shares of our common
stock with an estimated fair value of $583,000. We accounted for the acquisition
using the purchase method of accounting.


     On  April  7,  1999,  we  were  acquired  by  Bridge  in a  stock-for-stock
transaction that was accounted for as a "purchase  transaction" under Accounting
Principles  Board  Opinion No. 16.  Under the terms of the  transaction,  Bridge
issued  approximately  3,011,000  shares  of  its  common  stock  together  with
approximately  239,000  options and warrants on its common stock in exchange for
all of  our  outstanding  equity  securities.  Since  the  purchase  transaction
resulted in our company becoming a wholly owned subsidiary of Bridge,  SEC rules
required us to establish a new basis of accounting for the assets  purchased and
liabilities  assumed.  As a result, the purchase price has been allocated to the
underlying  assets  purchased and  liabilities  assumed based on estimated  fair
market value of these assets and  liabilities on the  acquisition  date, and the
difference  between the purchase price and the fair market value was recorded as
goodwill.  The accounting for the purchase transaction has been "pushed down" to
our financial statements. The impact of the acquisition on our balance sheet, as
a  result  of  the  application  of  fair  value  accounting,  was  to  increase
intangibles,  goodwill,  other liabilities and stockholders' equity. As a result
of the  acquisition  and the "push down"  accounting,  our results of operations
following the acquisition,  particularly our depreciation and amortization,  are
not comparable to our results of operations prior to the acquisition.


     On September 10, 1999, Bridge sold in a private placement approximately 25%
of its equity  ownership in SAVVIS to the existing  stockholders  of Bridge,  at
which time Welsh Carson  purchased  from Bridge a 12% interest in SAVVIS at that
time. On February 28, 2000, Bridge completed the sale of an additional 6,250,000
shares of SAVVIS common stock to Welsh Carson at $24 per share, for a total cash
consideration of $150 million. Bridge and Welsh Carson now own approximately 49%
and 16% of SAVVIS common stock, respectively.


     Simultaneously  with the completion of the initial  public  offering of our
common stock in February 2000, we acquired  Bridge's  global  Internet  protocol
network,  which has been  integrated  with our network since September 1999, for
total  consideration  of  approximately  $88 million and we paid a  preferential
distribution to Bridge of  approximately  $58 million.  At that time, we entered
into a 10-year  network  services  agreement  with  Bridge  under  which we will
provide  managed  data  networking   services  to  Bridge.   The  purchase  will
substantially increase our depreciation and amortization.  Our initial fees will
be based upon the cash cost to Bridge of operating  the network as configured on
October  31,  1999,  as  adjusted  for  changes to the  network  and  associated
personnel  related to Bridge's network  requirements  through February 17, 2000.
Our fees for additional  services provided  following  February 17, 2000 will be
set for a three-year term based on an agreed price schedule.  The price schedule
for additional services will be


                                       38
<PAGE>

subject to annual review and  negotiation  between Bridge and SAVVIS and will be
mutually agreed upon by Bridge and SAVVIS or determined by binding  arbitration.
Bridge has agreed to pay us a minimum of $105  million,  $132  million  and $145
million for network services in 2000, 2001 and 2002, respectively.

     In  addition,  Bridge  has  agreed  that the  amount  paid to us under  the
agreement for the fourth, fifth and sixth years will not be less than 80% of the
total  amount paid by Bridge and its  subsidiaries  for Internet  protocol  data
transport  services in each of those years;  and the amount paid to us under the
agreement  for the seventh  through tenth years will not be less than 60% of the
total  amount paid by Bridge and its  subsidiaries  for Internet  protocol  data
transport services in each of those years.

     Because under the network services agreement the amounts paid to us for the
services to be provided over the original network acquired from Bridge are based
upon the cash cost to operate the original network,  the purchase of the network
and provision of services  under the network  services  agreement will result in
losses  and  negative  cash flow from  operations  until we can sell  additional
services over that network to Bridge or other customers. However, because Bridge
is paying us the cash cost to operate the  original  network  and the  estimated
total cost for additional network facilities,  we expect any additional revenues
generated from the use of the network to generate higher  incremental  operating
margins.

     Bridge has agreed to provide to us various  services,  including  technical
support,  customer support and project  management in the areas of installation,
provisioning,  help desk, and repair and maintenance.  In addition,  Bridge will
agree to provide to us additional  administrative and operational services, such
as payroll and accounting functions,  benefit management and office space, until
we develop the  capabilities to perform these services  ourselves.  We expect to
generally develop many of these capabilities by the end of 2000.

     Revenue.  Our  revenue  will be  derived  primarily  from  the sale of data
networking,  Internet access and colocation services. Through December 31, 1998,
our revenue was primarily  derived from the sale of Internet  access services to
local and regional Internet service providers in the United States. Beginning in
late 1998, we also began to offer Internet  security and colocation  services to
corporate customers. Beginning in September 1999, we began to offer managed data
networking services.

     We charge each customer an initial  installation  fee that typically ranges
from  $500 to  $5,000  and a fixed  monthly  fee that  varies  depending  on the
services  provided,  the bandwidth used and the quality of service level chosen.
Our customer  agreements  are typically for 12 to 36 months.  As of December 31,
1999, approximately 6% of our customer agreements, representing approximately 6%
of our revenues for the month of December  1999,  were  month-to-month  and were
able to be terminated on 30 days' notice.  We expect the proportion of customers
on  month-to-month  agreements will continue to decrease as we add new customers
and our sales force continues to pursue longer renewals.

     Prices for  telecommunication  services,  including  the services we offer,
have  decreased  significantly  over the past  several  years and we expect this
trend to continue for the foreseeable future.

     We expect that a  substantial  portion of our revenues will be generated by
our network services agreement with Bridge. Assuming we had received the minimum
revenues  under  the  network  services  agreement  for  the  first  year of the
agreement in 1999,  Bridge would have represented  approximately 83% of our 1999
revenues.  As of December 31,  1999,  Bridge had an  estimated  135,000  trading
terminals  connected to the SAVVIS ProActiveSM  Network and an estimated 100,000
trading  terminals  connected  over networks using older  protocols.  Bridge has
informed us that it expects to convert its  remaining  customers to the Internet
protocol  network over the next three years. We expect that, to the extent these
customers are converted, Bridge will order additional services from us under the
network  services  agreement.  We cannot assure you that any of these  customers
will be converted or as to what schedule any conversions will be completed.

     While we expect our  revenues  from Bridge to  increase,  we expect them to
decrease as a percentage of our total revenues as we expand our data networking,
Internet  access and colocation  customer  base. We believe data  networking and
colocation  services will increase as a percentage of our  non-Bridge  recurring
revenues as we expand these service offerings.


                                       39

     DIRECT  COSTS  AND EXPENSES. Direct costs and expenses are comprised of the
following items:

     Data  communications  and operations.  Data  communications  and operations
expenses include the cost of:

     o connections to other Internet service providers;

     o leasing local access lines;

     o transmission connections;


     o engineering salaries and related benefits;


     o other related repairs and maintenance items;


     o leasing routers and switches;


     o leasing colocation space; and


     o installing local access lines at customer sites.


     These costs will also include the cost of the network operations center, as
well as the  customer  help desk and other  services  that will be  provided  by
Bridge  under  the  technical  services   agreement.   Data  communications  and
operations expenses will increase significantly with the inclusion of the Bridge
network. In addition,  we expect that these costs will increase in total dollars
as we expand our network and increase our customer base, but we expect that they
will decrease as a percentage of revenues.


     Selling,  general and administrative.  Selling,  general and administrative
expenses include the cost of:


     o sales and marketing salaries and related benefits;


     o advertising and direct marketing;


     o sales commissions and referral payments;


     o office rental;


     o administrative support personnel;


     o bad debt expense; and


     o travel.


     We anticipate  that these  expenses will  increase  significantly  in total
dollars as we add more sales personnel and administrative  support personnel and
increase our  marketing  initiatives  to support the  acquisition  of the Bridge
network and for the expansion of our customer base. Annual facility expenses are
expected to  increase  significantly  beginning  in the year 2000 as a result of
newly leased headquarters  facility in Herndon,  Virginia.  Our incremental cost
will  approximate  $2 million per year. We expect noncash  compensation  expense
will  materially  increase as a result of stock options  granted to employees of
SAVVIS and Bridge.  During the period from October  through  December  1999,  we
granted  2,843,258  stock  options  with an  exercise  price of $.50 per  share.
Noncash  compensation cost based upon the difference  between the exercise price
and the imputed fair value of our common stock as of the respective option grant
dates  totaling  approximately  $51 million  will be  recorded  over the vesting
periods of such options,  which  periods range from  immediate up to four years.
Approximately $1.5 million of noncash  compensation  expense was recorded in the
fourth quarter of 1999.


     Depreciation  and  amortization.   Depreciation  and  amortization  expense
consists  primarily  of the  depreciation  and  amortization  of  communications
equipment, capital leases, goodwill and intangibles. We expect these expenses to
increase  as we make  significant  investments  in the  network as we expand our
business.  Generally,  depreciation is calculated using the straight-line method
over the useful life of the  associated  asset,  which ranges from three to five
years. Goodwill resulting from our acquisition by Bridge is being amortized over
three years and other intangibles are being amortized over one to three years.


                                       40
<PAGE>

     Interest expense. Historical interest expense is related to indebtedness to
banks,   convertible  notes,  loans  from  Bridge  and  capitalized  leases.  In
connection with our purchase of Bridge's  Internet  protocol network assets,  we
will enter into  capitalized  leases with Bridge  relating to their  capitalized
leases for network  equipment that Bridge could not directly  assign to us. As a
result, our interest expense will increase.

     Income tax expense.  We incurred  operating  losses from inception  through
December 31, 1999 and, therefore, have not recorded a provision for income taxes
in our historical financial  statements.  We have recorded a valuation allowance
for  the  full  amount  of our  net  deferred  tax  assets  because  the  future
realization of the tax benefit is uncertain. As of December 31, 1999, we had net
operating loss carry forwards of approximately  $48 million.  Section 382 of the
Internal  Revenue Code  restricts the  utilization  of net operating  losses and
other  carryover tax attributes upon the occurrence of an ownership  change,  as
defined.  Such an  ownership  change  occurred  during  1999 as a result  of the
acquisition of our company by Bridge.  Management  believes that this limitation
may  restrict  our  ability  to  utilize  the  net  operating  losses  over  the
carryforward periods ranging from 15 to 20 years.

     As we expand  our  network,  increase  our  employee  base to  support  our
expanded operations and invest in our marketing and sales operations,  we expect
our  losses,  net cash  used in  operating  activities  and  negative  EBITDA to
increase substantially for the foreseeable future.


RESULTS OF OPERATIONS

     The historical  financial  information  included in this Form 10-K will not
reflect our future results of operations, financial position and cash flows. Our
results of  operations,  financial  position  and cash flows  subsequent  to the
purchase of Bridge's network and the commencement of the related agreements will
not be comparable to prior periods.


 Period from January 1, 1999 to April 6, 1999 (Predecessor)

     For the period  from  January  1, 1999 to April 6,  1999,  which is the day
before the acquisition by Bridge of our company,  revenue was approximately $5.4
million.  Data  communications  and  operations  expenses  for the  period  were
approximately $6.4 million,  and selling,  general and  administrative  expenses
were approximately $4.8 million.  Depreciation and amortization expenses for the
period January 1, 1999 to April 6, 1999 were approximately $.8 million. An asset
impairment  charge of  approximately  $1.4 million was also recorded during this
period.  Interest expense,  net, was $.1 million and the net loss for the period
was approximately $8.1 million.


 Period from April 7, 1999 to December 31, 1999 (Successor)

     For the period from April 7, 1999,  which is the date of the acquisition by
Bridge of our company,  to December 31, 1999, revenue increased to approximately
$18.5 million.  Data  communications and operations expenses for the period were
approximately $21.4 million,  and selling,  general and administrative  expenses
increased to approximately $20.2 million. Depreciation and amortization expenses
for the period increased to approximately $14.4 million, due to the amortization
of goodwill and other  intangible  assets  associated  with the  acquisition  by
Bridge.  Interest expense, net, was $1.3 million and the net loss for the period
was approximately $38.6 million.


 Year Ended December 31, 1999 Compared to Year Ended December 31, 1998

     The following  discussion  compares combined  information of SAVVIS and our
predecessor  for the year ended December 31, 1999, with those of our predecessor
for the year ended December 31, 1998. The combined  information  consists of the
sum of the  financial  data from January 1, 1999  through  April 6, 1999 for the
predecessor  and from April 7, 1999 through  December  31, 1999 for SAVVIS.  The
acquisition  by Bridge  resulted in a new basis of  accounting,  which  impacted
depreciation and amortization in the period subsequent to April 7, 1999.

     Revenue.  Revenue was $24.0  million in 1999  compared to $13.7  million in
1998,  an increase of 74%.  This $10.3  million  increase was  primarily  due to
increased  marketing and sales efforts and the resulting  increase in the number
of customers from 476 to 872.


                                       41
<PAGE>

     Data  Communications  and Operations.  Data  communications  and operations
expenses  were $27.8  million in 1999,  compared  to $20.9  million in 1998,  an
increase of 33%. This $6.9 million increase was due to costs associated with the
expansion of our network and the increase in the customer base.

     Selling,  General and Administrative.  Selling,  general and administrative
expenses  were $24.9  million in 1999,  compared  to $12.2  million in 1998,  an
increase of 104%.  The principal  increase in these  expenses  resulted from the
increased size of our sales force in 1999.  Marketing and  administrative  costs
also increased in 1999 to support the increased number of customers.


 Year Ended December 31, 1998 Compared to Year Ended December 31, 1997

     Revenue.  Revenue was $13.7  million in 1998  compared  to $2.8  million in
1997,  an increase of 389%.  This $10.9  million  increase was  primarily due to
increased  marketing and sales efforts and the resulting  increase in the number
of customers from 102 to 476.

     Data  Communications  and Operations.  Data  communications  and operations
expenses  were $20.9  million in 1998,  compared  to $11.1  million in 1997,  an
increase of 88%. This $9.8 million increase was due to costs associated with the
expansion of our network and the increase in the customer base.

     Selling,  General and Administrative.  Selling,  general and administrative
expenses  were  $12.2  million in 1998,  compared  to $5.1  million in 1997,  an
increase of 139%.  The principal  increase in these  expenses  resulted from the
increased  size of our sales  force in the second  half of 1998.  Marketing  and
administrative  costs also increased in 1998 to support the increased  number of
customers.

     Depreciation and Amortization.  Depreciation and amortization expenses were
$2.3  million in 1998,  compared  to $.6  million in 1997,  an increase of 283%.
Depreciation  and  amortization   expense  increased  due  to  the  purchase  of
communications equipment for the expansion of our network and the acquisition of
Interconnected Associates.

     Interest  Expense,  Net.  Interest  expense,  net was $.1  million in 1998,
compared to $.5 million in 1997,  a decrease of 80%.  This $.4 million  decrease
was directly  attributed to the conversion of a portion of our convertible notes
into equity securities in connection with our corporate  reorganization in March
1998 and interest income earned on proceeds received in the transaction.

     Net Loss. Net loss was $20.0 million in 1998, which included a $2.0 million
extraordinary gain on debt extinguishment,  compared to $14.0 million in 1997, a
43% increase.


LIQUIDITY AND CAPITAL RESOURCES

     We have  historically  generated  negative cash flows from  operations.  We
generated  negative cash flows from  operations of $10.5 million,  $20.6 million
and $24.5 million for 1997, 1998 and 1999, respectively.

     From January 1, 1996 through  December 31, 1999, we expended  approximately
$110 million for operating  purposes and for the  construction,  maintenance and
expansion  of  our  network.   Net  cash  used  in  investing   activities   was
approximately  $.7 million,  $2.4  million and $1.1  million for 1997,  1998 and
1999,  respectively.  Net  cash  used in  investing  activities  in each  period
primarily reflects purchases of property and equipment not financed with capital
leases. In March 1998, we used  approximately $.8 million in cash and stock with
a fair value of approximately $.6 million to acquire Interconnected  Associates.
See  note 4 to our  audited  financial  statements  that are in the back of this
filing.  Net cash  provided by financing  activities  was $12.0  million,  $24.1
million and $25.9  million for 1997,  1998 and 1999,  respectively.  We obtained
funds  through  issuances  of equity  securities  and  convertible  notes,  bank
financing,  capital lease  obligations and advances from Bridge.  As of December
31,  1999,  we had  outstanding  advances  from  Bridge of  approximately  $24.1
million.

     Our capital  expenditures  totaled  approximately $1.1 million for 1999. We
expect to have  capital  expenditures,  excluding  the  purchase  of the  Bridge
network assets, of approximately $149 million in 2000 as we build out colocation
facilities, deploy ATM devices and expand our network to 24 new cities.


                                       42
<PAGE>

     On February 18, 2000, we acquired Bridge's Internet protocol network assets
for total  consideration  of  approximately  $88 million.  Of this  amount,  $25
million was paid by entering into a capital lease  obligation  with Bridge.  The
remaining  purchase  price of $63  million  was paid with a  portion  of the net
proceeds  from the  initial  public  offering of common  stock.  We also paid to
Bridge,  out of the offering proceeds,  an approximate $58 million  preferential
distribution.  At the  request of a lender,  approximately  $ 2.5 million of the
capitalized principal obligation was paid in March 2000.

     In connection with our purchase of the network assets, we also entered into
a network  services  agreement  with Bridge  under which we provide  Bridge with
managed  data  networking  services.  Because the  amounts  paid to us under the
network services  agreement for the services  provided over the original network
acquired  from  Bridge  are based  upon the cash cost to  operate  the  original
network,  the  provision  of such  services  will not have an impact on our cash
flows from operations. However, due to amortization and depreciation relating to
the network, the provision of services under the network services agreement will
result in our  incurring  losses from  operations  until we can sell  additional
services over the network to Bridge or to other  customers.  The effects of such
operating losses will include continued increases in our accumulated deficit and
reductions in stockholders' equity.

     In connection  with our acquisition of Bridge's  network assets,  Bridge is
assigning to us numerous agreements for the purchase of communications services.
We are  currently  discussing  with several of these  suppliers the placement of
deposits or stand-by  letters of credit by us in return for their consent to the
assignment.

     We have arrangements with various suppliers of communications services that
require us to maintain minimum spending levels some of which increase over time.
Our aggregate  minimum spending level is  approximately  $28 million in 2000. In
specific  instances,  we are able to choose  among a variety  of  communications
services offered to meet these spending minimums. We are currently exceeding all
of our  spending  minimums  and  expect  to  continue  to do so as  our  network
requirements expand.  However, if our network requirements were to decrease,  we
could be obligated to make  payments to these  suppliers  for services we do not
need.

     Although  we plan to  invest  significantly  in  equipment  and in  network
expansion,  except as described in the preceding paragraph,  we have no material
commitments for such items at this time. As we expand our network,  increase our
employee base to support our expanded operations and invest in our marketing and
sales  organizations,  we expect to have significant  cash  requirements for the
foreseeable future.

     We believe that the net proceeds of the initial public  offering,  together
with our  existing  cash and cash  equivalents,  will  allow us to  continue  in
business as a going  concern and will be  sufficient  to fund our  operating and
capital needs through  2000. We are currently in  discussions  with two separate
vendors to obtain vendor financing for network equipment purchases, and a number
of  institutions  for  the  financing  of  two  data  centers   currently  under
construction.  We will need to raise a significant amount of capital to fund our
capital expenditures, operating deficits, working capital needs and debt service
requirements  after  2000.  We intend  to seek  equity  or debt  financing  from
external  sources to meet our cash needs after 2000.  We cannot  assure you that
such additional funding will be available on terms satisfactory to us or at all.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial  Accounting Standards Board issued Statement of
Financial Accounting  Standards No. 133, "Accounting for Derivative  Instruments
and Hedging  Activities," which establishes  accounting and reporting  standards
for derivative  instruments and hedging  activities.  As amended by Statement of
Financial  Accounting  Standards No. 137, this standard will be effective for us
for the fiscal years and quarters  beginning  after June 15, 2000,  and requires
that an entity  recognize all derivatives as either assets or liabilities in the
statement of financial  position and measure those instruments at fair value. We
are currently evaluating the impact of this standard.

     In April 1998,  the  American  Institute of  Certified  Public  Accountants
issued  Statement  of  Position  98-5,  "Reporting  on  the  Costs  of  Start-Up
Activities." This standard  required  companies to expense the costs of start-up
activities and organization costs as incurred and was effective for fiscal years
beginning  after December 15, 1998. The adoption of the statement did not have a
material impact on our results of operations.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     Our primary  market  risk  exposures  relate to changes in interest  rates.
Following the purchase of Bridge's  global Internet  protocol  network assets in
February  2000, we have begun to expand our business  internationally,  and as a
result, we will be exposed to changes in foreign currency exchange rates.

     Our financial  instruments  that are sensitive to changes in interest rates
are our  borrowings  from Bridge,  all of which were entered into for other than
trading purposes,  and bear interest at a fixed rate of 8%. Because the interest
rate on these  advances is fixed,  changes in interest  rates will not  directly
impact our cash flows.  As of December  31, 1999 and 1998,  the  aggregate  fair
value of our borrowings approximated their carrying value.

     Prior to our purchase of the network  assets from Bridge in February  2000,
changes in foreign  exchange rates did not impact our results of operations.  We
expect  approximately  18%  of  our  revenue  from  Bridge  to be  derived  from
operations  outside the United States, and approximately 17% of our direct costs
to be incurred  outside the United  States.  Because  our foreign  revenue  will
closely match our foreign costs,  we do not  anticipate  that changes in foreign
exchange rates will have a material impact on our results of operations.  We may
engage in hedging transactions to mitigate foreign exchange risk.

Section 16(a) Beneficial Ownership Reporting Compliance

     Section 16(a) of the Securities Exchange Act of 1934 requires our executive
officers and directors,  and persons who  beneficially own more than ten percent
of our common stock, to file initial reports of ownership and reports of changes
in ownership  with the SEC.  However,  during fiscal 1999 we were not subject to
the reporting  requirements of the Securities Exchange Act and, accordingly,  no
such reports were filed during 1999.


ITEM 11. EXECUTIVE COMPENSATION

     The following table provides you with information about compensation earned
during fiscal 1999 by our Chief Executive Officers and the other two most highly
compensated  executive  officers  employed by us, whose salaries and bonuses for
such year were in excess of $100,000. We use the term "named executive officers"
to refer to these officers in this report.

OPTION GRANTS IN LAST FISCAL YEAR


     The  following  table  shows  grants of stock  options to each of the named
executive  officers during 1999. The percentages in the table below are based on
options to purchase a total of 5,159,508  shares of our common stock  granted to
our employees and directors in 1999. The exercise price per share of each option
was equal to the fair market  value of the common  stock on the date of grant as
determined by the  compensation  committee of our board of directors.  Potential
realizable  values are net of exercise  price  before taxes and are based on the
assumption  that  our  common  stock  appreciates  at  the  annual  rate  shown,
compounded annually, from the date of grant until the expiration of the ten-year
term. The numbers are calculated based on the requirements of the SEC and do not
reflect our estimate of future stock price growth.

    the balance of the shares at the rate of 8,333 shares per month beginning on
    the first  anniversary  of the date of the option  grant  through the fourth
    anniversary of the date of grant.  Our right to repurchase these shares will

AGGREGATE OPTION EXERCISES IN 1999 AND FISCAL YEAR-END OPTION VALUES


     The  following  table sets forth as of December 31,  1999,  for each of the
named  executive  officers  listed  the total  number of  shares  received  upon
exercise of options  during 1999,  the value  realized upon that  exercise,  the
total number of  unexercised  options to purchase our common stock and the value
of such options which were in-the-money at December 31, 1999.


     There was no public  trading market for our common stock as of December 31,
1999.  Accordingly,  in order to present the values  realized  upon  exercise of
options  and the  values of  unexercised  in-the-money  options  shown  below we
subtracted the applicable exercise price from a price of $24.00 per share, which
was the initial public offering price of our common stock.

ARRANGEMENTS WITH EXECUTIVE OFFICERS

     Arrangement with Mr. Heintzelman.  Mr. Heintzelman became our President and
Chief Executive Officer under an employment agreement dated December 4, 1998. On
November 12, 1999, we entered into an additional  agreement with Mr. Heintzelman
in  connection  with his  resignation,  entitling him to continue to receive his
base salary of  approximately  $20,800 per month  through  December 3, 2000.  In
addition,  under these  agreements,  Mr.  Heintzelman  is entitled to a prorated
portion  of his bonus for 1999 in an  amount to be  established  by our board of
directors,  but in no event less than 25% of his annual base  salary.  Under the
agreement dated November 12, 1999, Mr.  Heintzelman agreed to serve on our board
of directors for a one-year term that will expire in November of 2000. While Mr.
Heintzelman  will not separately be compensated for his services on the board of
directors  during  this  one-year  term,  he will  continue  to be  eligible  to
participate  in benefit  plans as though he had remained  employed by us. All of
Mr.  Heintzelman's stock options vested fully on the date of his resignation and
Mr. Heintzelman has exercised all of his options since that date.


     In his employment  agreement of December 4, 1998, Mr. Heintzelman agreed to
preserve  the  confidentiality  and the  proprietary  nature of all  information
relating to us and our business for three years after the term of his agreements
ends. In addition,  Mr.  Heintzelman  is obligated  under this  agreement not to
compete  with us and not to solicit the business of our  customers  for one year
following the term of his employment agreement. He will assist in the transition
of his position and help to ensure our ability to retain our key employees.  Mr.
Heintzelman  has also  released our company,  Bridge and Bridge's  employees and
directors from all claims arising from his employment.


     Arrangement  with  Mr.  Finlayson. On December 28, 1999, we entered into an
agreement  with  Mr.  Finlayson  pursuant  to  which  he  agreed to serve as our
President  and  Chief  Operating  Officer effective December 31, 1999. Under his
agreement,  Mr.  Finlayson is entitled to a base salary of $400,000 per year. In
addition,  he  will  be  eligible  to receive an annual incentive bonus of up to
$600,000  based  on  the  achievement  of  mutually  agreed  to  objectives. Mr.
Finlayson  will  be entitled to a minimum annual incentive bonus of $400,000 for
the  year  ended  2000.  Mr. Finlayson will be entitled to benefits commensurate
with those available to other senior executives.


                                       49
<PAGE>

     In  connection  with his  employment,  Mr.  Finlayson  received  options to
purchase  650,000  shares of our common  stock at an exercise  price of $.50 per
share, 200,000 of which vested on December 31, 1999. Mr. Finlayson had the right
to sell 50,000 shares  underlying these options  immediately,  and the remaining
150,000  shares on a monthly  pro rata basis over the  calendar  year 2000.  The
remaining  450,000  shares  vested on January 3, 2000,  and become  salable on a
monthly pro rata basis over calendar years 2001,  2002 and 2003.  Mr.  Finlayson
may sell all of his shares in the event of a change in  control of our  company,
the sale of  substantially  all of our assets,  if we terminate  his  employment
without cause,  or if he resigns for good reason.  However,  if we terminate Mr.
Finlayson's  employment for good cause, we will have the right to buy all shares
not yet salable at the price he paid for the shares. Mr. Finlayson will have the
right to exercise all vested  options for one year after the  termination of his
employment unless his employment was terminated for cause.


     In the event we terminate Mr. Finlayson's employment without cause or if he
terminates his employment for good reason, he will be entitled to receive a lump
sum severance payment equal to his then current base annual salary,  which shall
not be less than his highest  annual salary paid by us. In the event of a change
in control of our company,  Mr.  Finlayson has agreed to remain with our company
for a period of up to twelve months if the new management requests him to do so.
We will reimburse Mr. Finlayson for any parachute taxes he would incur under the
Internal Revenue Code as a result of such a change in control.  We may terminate
Mr.  Finlayson's  employment for cause at any time without notice, in which case
he will not be entitled to any severance benefits.


     Arrangement with Mr.Frear. On June 14, 1999, we entered into an arrangement
with Mr.  Frear  pursuant  to which he agreed  to serve as our  Chief  Financial
Officer.  As part of this  arrangement,  Mr. Frear is entitled to an annual base
salary  of  $250,000,   subject  to  periodic  review  and  adjustment,   and  a
discretionary annual bonus of approximately 50% of his base salary, based on his
personal and overall  corporate  performance.  Mr. Frear is entitled to medical,
disability,  401(k),  life insurance and other  benefits in accordance  with our
general policies.


     In connection  with his employment,  Mr. Frear received  400,000 options to
purchase shares of our common stock at an exercise price of $.50 per share.  All
of Mr. Frear's  options have vested.  In the event Mr. Frear were to resign,  we
would have the right to  repurchase  the shares that have been  purchased by Mr.
Frear  upon  exercise  of the  options at fair  market  value or $.50 per share,
whichever is lower. This repurchase right was terminated with respect to a total
of 100,000  shares at the  completion  of our initial  public  offering and with
respect  to the  balance  of the  shares at the rate of 8,333  shares  per month
beginning on the first  anniversary  of the date of the option grant through the
fourth  anniversary of the date of grant.  Our right to repurchase  these shares
will be  terminated  in the  event of a change in  control  of our  company.  In
addition,  upon  completion of the initial public  offering,  Mr. Frear received
options at an exercise price per share equal to the in initial  public  offering
price of $24.00 per share. The options have a term of ten years.


     If we were to terminate Mr. Frear's  employment  without  cause,  or if Mr.
Frear were to  terminate  his  employment  for good  reason,  Mr. Frear would be
entitled to salary  continuation  and  continuation of all benefits for one year
following the  termination of his employment and a pro rata payment of his bonus
through the date of termination. In addition, our right to repurchase his shares
would be terminated.


     Arrangement  with Mr.  Mori.  On  September  30,  1999,  we entered into an
agreement with Mr. Mori pursuant to which he became our Executive Vice President
and General Manager -- Americas  effective October 1, 1999. Under his agreement,
Mr.  Mori is  entitled  to an  annual  base  salary  of  $200,000,  as well as a
discretionary  bonus of 50% to 100% of his base salary based on his personal and
overall  corporate  performance.  We also  granted Mr. Mori  options to purchase
225,000 shares of our common stock at an exercise  price of $.50 per share.  All
of Mr.  Mori's  options  have vested.  In the event Mr. Mori were to resign,  we
would have the right to  repurchase  any shares that have been  purchased by Mr.
Mori upon  exercise  of the  options  at fair  market  value or $.50 per  share,
whichever  is lower.  This  repurchase  right is  terminated  at a rate of 4,687
shares per month and will  terminate  on the fourth  anniversary  of the date of
grant. Under his agreement,  Mr. Mori is entitled to benefits  commensurate with
those available to Bridge executives of comparable rank.


                                       50
<PAGE>

     If we were to terminate  Mr. Mori's  employment  without cause prior to the
second  anniversary of his  employment,  Mr. Mori would be entitled to receive a
severance  payment of $450,000.  In the event we terminate Mr. Mori's employment
without cause after the second anniversary of his employment,  and either we are
not a public  company or we are a public  company  and our shares on the date of
termination  trade at a price  less than $15 per  share,  Mr.  Mori  would  also
receive a payment of  $450,000.  Mr. Mori will  receive a similar  payment if he
were to  resign  as a result of an  acquisition  of more than 30% of our  voting
shares by an entity other than Bridge,  if he were to be  instructed to relocate
from  the St.  Louis  metropolitan  area,  or if he were to be  reassigned  to a
position  entailing  materially  reduced  responsibilities  or opportunities for
compensation.


DIRECTOR COMPENSATION

     Directors who are also employees of our company will not receive additional
compensation for serving as a director.  Each director who is not an employee of
our company will receive an annual retainer of $15,000, together with a grant of
options to purchase shares of our common stock under our stock option plan at an
exercise  price equal to fair market  value on the date of grant.  On January 3,
2000,  Messrs.  Welsh,  Wendel and  McInerney  each received  15,000  options to
purchase  shares of our common  stock under our stock option plan at an exercise
price of $.50 per share. The options will vest immediately on the date of grant,
but if a director  ceases to serve on our board of  directors,  we will have the
right to repurchase  these shares at the lower of the exercise price or the fair
market  value of the  shares.  Our  right to  repurchase  these  shares  will be
terminated  with  respect  to one  fourth of the  shares  on each of the  first,
second, third and fourth anniversaries of the date of the option grant.


COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     Mr.  Wendel,  a director of our company, is also President, Chief Executive
Officer  and  Chairman of the Board of Bridge. Messrs. McInerney and Welsh serve
as  directors  of  our  company,  as  well  as directors of Bridge. In addition,
Messrs.  McInerney  and  Welsh  are  general  partners  of  Welsh  Carson, which
sponsors  investment  partnerships,  three  of  which  are  among  our principal
stockholders and two of which are also principal stockholders of Bridge.

     In 1999,  none of our executive  officers served as a director or member of
the compensation committee of another entity whose executive officers had served
on our board of directors or on our compensation committee.


STOCK OPTION PLAN

     Background.  On July 22, 1999, our board of directors approved the adoption
of our 1999 SAVVIS stock option plan,  and our  stockholders  approved the stock
option  plan on the same  date.  On  December  7,  1999,  the board  adopted  an
amendment to the stock option plan approving an increase in the number of shares
of common stock  available  for issuance  under the plan,  and our  stockholders
approved the  amendment on that same date.  The purpose of our 1999 stock option
plan is to  enhance  our  ability  to  attract,  retain  and  compensate  highly
qualified employees and other individuals providing us with services. The option
plan permits the granting of options to purchase shares of common stock intended
to qualify as incentive  stock options under the Internal  Revenue Code of 1986,
or the Internal Revenue Code, and options that do not qualify as incentive stock
options,  or  non-qualified  options.  Grants may be made under our stock option
plan to employees and directors of our company or any related company and to any
other individual  whose  participation in the stock option plan is determined by
our  board of  directors  to be in our best  interests.  As of March  15,  2000,
options to purchase  2,957,897 shares of common stock were outstanding under the
stock option plan.  No options may be granted  under the stock option plan after
July 22, 2009.

     The  number of shares of common  stock  available  for  issuance  under the
option plan is 12,000,000 subject to adjustment for stock dividends,  splits and
other similar  events.  If any shares of common stock covered by a grant are not
purchased or are forfeited, or if a grant otherwise terminates without delivery



                                       51
<PAGE>

of any shares of common stock  subject to the option,  then the number of shares
of common stock counted  against the total number of shares  available under the
stock  option plan with  respect to such grant  will,  to the extent of any such
forfeiture or termination,  again be available for making grants under the stock
option plan.

     The stock option plan is administered by our  compensation  committee.  The
compensation  committee has the full power and authority to take all actions and
to make all determinations  required or provided for under the plan, any option,
or option agreement, to the extent such actions are consistent with the terms of
the plan. The board of directors may take any action the compensation  committee
is  authorized  to  take.  To the  extent  permitted  by law,  the  compensation
committee or board may delegate its authority  under the plan to a member of the
board or one of our executive officers.

     Option  Terms.  The option price of each option will be  determined  by the
compensation  committee.  However,  the option price may not be less than either
100% of the fair market  value of our common  stock on the date of grant or less
than par value in the case of  incentive  stock  options and less than par value
only in the case of non-qualified  stock options.  To qualify as incentive stock
options, options must meet various federal tax requirements, including limits on
the value of shares  subject to  incentive  stock  options  which  first  become
excercisable  in any one calendar  year,  and a shorter term and higher  minimum
exercise price in the case of any grants to 10% stockholders.

     The term of each option will be fixed by the  compensation  committee.  The
compensation  committee  will determine at what time or times each option may be
exercised and the period of time, if any, after retirement, death, disability or
termination of employment  during which options may be exercised.  However,  all
options shall  automatically vest upon a termination of employment caused by the
optionee's death, disability, or retirement. Options may be made excercisable in
installments,  and the compensation  committee may accelerate the exercisability
of options,  as well as remove any  restrictions on such options.  Except to the
extent  otherwise  expressly  set forth in an  option  agreement  relating  to a
non-qualified  option,  options are not  transferable  other than by will or the
laws of descent and distribution.  The compensation committee may include in any
option agreement any provisions relating to forfeitures of options that it deems
appropriate,  including  prohibitions  on  competing  with our company and other
detrimental conduct.

     If an optionee elects to exercise his or her option, he or she must pay the
option exercise price in full either in cash or cash equivalents.  To the extent
permitted by the option  agreement or the compensation  committee,  the optionee
may also pay the option  exercise price by the delivery of common stock,  to the
extent  that the  common  stock is  publicly  traded,  or  other  property.  The
compensation  committee  may also  allow the  optionee  to defer  payment of the
option  price,  or may cause us to loan the option  price to the  optionee or to
guarantee  that any shares to be issued will be  delivered to a broker or lender
in order to allow the optionee to borrow the option price.  If the  compensation
committee so permits, the exercise price may also be delivered to us by a broker
pursuant to irrevocable instructions to the broker from the participant.

     Corporate  Transactions.  Options  granted under the stock option plan will
terminate in connection  with  corporate  transactions  involving our company as
listed below,  except to the extent the options are continued or substituted for
in connection with the transaction. In the event of a termination of the options
in  connection  with a  corporate  transaction  and  subject to any  limitations
imposed in an applicable option agreement,  the options will be fully vested and
exercisable for a period to be determined by the board of directors  immediately
before the  completion of the  corporate  transaction.  A corporate  transaction
occurs in the event of:

     o a dissolution or liquidation of our company;

     o a  merger, consolidation  or  reorganization  of our company  with one or
more other entities in which our company is not the surviving entity;

     o a  sale  of  substantially all of our assets to another person or entity;
or

   o  any transaction, including, without limitation, a merger or reorganization
      in which our company is the surviving  entity,  approved by the board that
      results in any person or entity, other than


                                       52
<PAGE>

      persons  who are  holders of stock of our company at the time the plan was
      approved  by the  stockholders  and  other  than an  affiliate,  owning 80
      percent or more of the combined voting power of all classes of our stock.


     The board of directors  may also in its  discretion  and only to the extent
provided in an option agreement cancel outstanding  options in connection with a
corporate  transaction.  Holders of canceled  options will receive a payment for
each canceled option.

     Amendments and Termination. The board of directors may at any time amend or
discontinue  the stock  option  plan,  except that the maximum  number of shares
available for grant as incentive stock options and the class of persons eligible
to  receive  grants  under  the  plan  may not be  changed  without  stockholder
approval.

     Adjustments  for Stock  Dividends  and  Similar  Events.  The  compensation
committee will make  appropriate  adjustments  in outstanding  awards to reflect
common stock dividends, splits and other similar events.


Federal Income Tax Consequences

     Incentive Stock Options. The grant of an option will not be a taxable event
for the  optionee  or us. An optionee  will not  recognize  taxable  income upon
exercise of an incentive stock option,  except that the alternative  minimum tax
may  apply.  Any gain  realized  upon a  disposition  of common  stock  received
pursuant to the exercise of an incentive stock option will be taxed as long-term
capital gain the optionee holds the shares for at least two years after the date
of grant  and for one year  after  the date of  exercise,  known as the  holding
period requirement. if We will not be entitled to any business expense deduction
with respect to the exercise of an incentive  stock option,  except as discussed
below.

     For the exercise of an option to qualify for the foregoing  tax  treatment,
must be an employee of our company or a  subsidiary  from the date the option is
granted  through a date within  three  months  before the date of  exercise  the
optionee  generally  of the option.  In the case of an optionee who is disabled,
the  three-month  period for exercise  following  termination  of  employment is
extended  to one year.  In the case of an employee  who dies,  both the time for
exercising  incentive  stock options  after  termination  of employment  and the
holding period for common stock received  pursuant to the exercise of the option
are waived.

     If all of the  foregoing  requirements  are met except the  holding  period
requirement  mentioned above,  the optionee will recognize  ordinary income upon
the  disposition of the common stock in an amount  generally equal to the excess
of the fair  market  value of the  common  stock  at the  time  the  option  was
exercised over the option exercise price, but not in excess of the gain realized
on the sale.  The balance of the realized gain, if any, will be capital gain. We
will be  allowed  a  business  expense  deduction  to the  extent  the  optionee
recognizes  ordinary  income subject to Section  162(m) of the Internal  Revenue
Code, as summarized below.

     If an optionee  exercises  an incentive  stock  option by tendering  common
stock  with a fair  market  value  equal to part or all of the  option  exercise
price,  the  exchange of shares will be treated as a nontaxable  exchange.  This
nontaxable treatment would not apply,  however, if the optionee had acquired the
shares being  transferred  pursuant to the exercise of an incentive stock option
and had not satisfied the holding period  requirement  summarized  above. If the
exercise is treated as a nontaxable exchange, the optionee would have no taxable
income from the exchange and  exercise,  other than  minimum  taxable  income as
discussed  above,  and the tax basis of the shares exchanged would be treated as
the  substituted  basis for the shares  received.  If the  optionee  used shares
received  pursuant to the  exercise of an  incentive  stock  option,  or another
statutory  option,  as to which the optionee had not  satisfied  the  applicable
holding  period  requirement,  the  exchange  would  be  treated  as  a  taxable
disqualifying disposition of the exchanged shares.

     If, pursuant to an option  agreement,  we withhold shares in payment of the
option price for incentive stock options,  the transaction  should  generally be
treated as if the withheld shares had been sold in a  disqualifying  disposition
after exercise of the option, so that the optionee will realize ordinary income



                                       53
<PAGE>

with respect to such shares.  The shares paid for by the withheld  shares should
be treated as having been received  upon exercise of an incentive  stock option,
with the tax consequences described above. However, the Internal Revenue Service
has not  ruled  on the tax  treatment  of  shares  received  on  exercise  of an
incentive  stock option where the option  exercise  price is paid with  withheld
shares.

     Non-Qualified  Options.  The grant of an option will not be a taxable event
for the optionee or us. Upon exercising a non-qualified option, an optionee will
recognize  ordinary  income in an amount  equal to the  difference  between  the
exercise  price and the fair  market  value of the  common  stock on the date of
exercise.  However, if the optionee is subject to restrictions,  the measurement
date will be deferred,  unless the optionee makes a special tax election  within
30 days after  exercise.  Upon a subsequent  sale or exchange of shares acquired
pursuant to the  exercise of a  non-qualified  option,  the  optionee  will have
taxable gain or loss,  measured by the difference between the amount realized on
the  disposition and the tax basis of the shares.  This difference  generally is
the amount paid for the shares plus the amount treated as ordinary income at the
time the option was exercised.

     If  we  comply  with  applicable   reporting   requirements  and  with  the
restrictions of Section 162(m) of the Internal Revenue Code, we will be entitled
to a business  expense  deduction  in the same amount and  generally at the same
time as the optionee  recognizes  ordinary  income.  Under Section 162(m) of the
Internal Revenue Code, if the optionee is one of specified  executive  officers,
then,  unless a number  of  exceptions  apply,  we are not  entitled  to  deduct
compensation with respect to the optionee, including compensation related to the
exercise of shares  options,  to the extent such  compensation  in the aggregate
exceeds  $1.0 million for the taxable  year.  Options  issuable  under the stock
incentive  plan are intended to comply with the exception to Section  162(m) for
"performance-based" compensation.

     If the  optionee  surrenders  common stock in payment of part or all of the
exercise price for non-qualified  options,  the optionee will not recognize gain
or loss with respect to the shares surrendered, regardless of whether the shares
were acquired  pursuant to the exercise of an incentive  stock  option,  and the
optionee will be treated as receiving an equivalent number of shares pursuant to
the  exercise of the option in a  nontaxable  exchange.  The basis of the shares
surrendered  will be  treated  as the  substituted  tax basis for an  equivalent
number of option  shares  received  and the new shares will be treated as having
been  held for the same  holding  period  as had  expired  with  respect  to the
transferred  shares.  The difference between the total option exercise price and
the total fair market value of the shares  received  pursuant to the exercise of
the  option  will be taxed  as  ordinary  income.  The  optionee's  basis in the
additional shares will be equal to the amount included in the optionee's income.

     If, pursuant to an option  agreement,  we withhold shares in payment of the
option price for  non-qualified  options or in payment of tax  withholding,  the
transaction  should generally be treated as if the withheld shares had been sold
for an amount equal to the exercise price after exercise of the option.

401(K) PLAN

     In  January,   1998,  we  adopted  a  tax-qualified  employee  savings  and
retirement plan covering all of our employees. Under this 401(k) plan, employees
may elect to reduce their current compensation by a maximum pre-tax amount equal
to the lesser of 15% of  eligible  compensation  or the  statutorily  prescribed
annual limit,  which was $10,000 in 1998,  and have the amount of this reduction
contributed  to the 401(k)  plan.  The  trustee  under the 401(k)  plan,  at the
direction of each  participant,  invests the assets of the 401(k) plan in any of
four  investment  options.  The 401(k) plan is intended to qualify under Section
401 of the  Internal  Revenue  Code so that  contributions  by  employees to the
401(k)  plan,  and  income  earned on plan  contributions,  are not  taxable  to
employees until  withdrawn,  and so that the  contributions by employees will be
deductible by us when made. We may make matching or additional  contributions to
the 401(k) plan, in amounts to be determined annually by the board of directors.
Employees are immediately 100% vested in their individual contributions and vest
25% per year in our  contributions  beginning with their second year of service,
becoming   100%  vested  in  their  fifth  year  of  service.   Vesting  in  our
contributions   also  occurs  upon   attainment  of  retirement  age,  death  or
disability.  The 401(k) plan  provides  for  hardship  withdrawals  and employee
loans.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS


     Mr.  Wendel,  a director of our company, is also President, Chief Executive
Officer  and Chairman of the Board of Bridge. Mr. McCormick, our Chief Executive
Officer  and  the  Chairman of our Board, served as the Executive Vice President
and  Chief  Technical Officer of Bridge through December 1999. Messrs. McInerney
and  Welsh serve as directors of our company, as well as directors of Bridge. In
addition,  Messrs.  McInerney  and  Welsh  are general partners of Welsh Carson,
which  sponsors  investment partnerships, three of which are among our principal
stockholders and two of which are also principal stockholders of Bridge.


     As of December 31, 1999, we had amounts payable to Bridge of  approximately
$24 million.  These advances bear interest at a rate of 8% per year. We used the
proceeds of these loans to fund our working capital requirements.


     In February 2000, we entered into several agreements with Bridge, including
a master establishment and transition agreement, an equipment colocation permit,
a network services agreement,  an administrative services agreement, a technical
services  agreement,  the GECC Sublease and a local network services  agreement.
Summaries of these agreements are set forth below.


     Master Establishment and Transition Agreement. The master establishment and
transition agreement transferred Bridge's global Internet protocol network to us
for $88 million.  Under this  agreement,  a Bridge  subsidiary that owned all of
Bridge's U.S. network assets  transferred them to one of our  subsidiaries.  The
transfers  of non-U.S.  assets were  effected  under local  transfer  agreements
between the appropriate Bridge and SAVVIS subsidiaries.


     The transfer of several portions of the Bridge network requires contractual
consents from some of Bridge's counterparties or regulatory approvals in several
jurisdictions which have not yet been obtained.  Bridge will continue to own and
operate those portions of the network while we continue to seek the  appropriate
consents.  Under the master  establishment  and transition  agreement,  once the
requisite  consents and approvals  have been acquired in each  jurisdiction,  we
will have an obligation to purchase the assets from Bridge in that jurisdiction.
In  jurisdictions  where we expect the  purchase to occur within one year of the
closing date of the Bridge asset transfer, Bridge will operate the facilities on
our behalf and we will reimburse  Bridge for all costs directly  associated with
the use,  maintenance  and operation of those assets and we will be paid for the
use of those assets by Bridge under the network  services  agreement.  We expect
the asset transfer to occur in Greece, Ireland,  Hungary, Poland, Taiwan, Mexico
and Venezuela within one year from the closing date of the Bridge transfer.  Our
obligation to acquire these assets  expires upon the later of ten years from the
closing date or expiration of the network services agreement.


                                       56
<PAGE>

     Under  the  master  establishment  and  transition  agreement,   Bridge  is
responsible for all liabilities  associated with its Internet  protocol  network
prior to the transfer to us, and we are responsible  for  liabilities  after the
transfer.  The agreement  provides that we will indemnify Bridge for breaches of
our  representations  and warranties and with respect to our  responsibility for
our assumed liabilities.


     Network Services Agreement.  Under the network services agreement,  we have
agreed to provide Bridge with networks for the collection  and  distribution  of
the financial  information  provided by Bridge to its customers and for Bridge's
internal  managed data network  needs for ten years from the closing  date.  The
agreement may be extended by Bridge for an additional five-year period by giving
us notice one year before the  expiration  of the initial  ten-year  term.  Upon
termination of the agreement, we will be required to continue to provide network
services  to Bridge for an  additional  five  years,  at rates in effect for our
third party customers at the termination date.


     Bridge has agreed to pay us a minimum of $105  million,  $132  million  and
$145  million for  network  services in 2000,  2001 and 2002,  respectively.  In
addition,  Bridge has agreed that the amount paid to us under the  agreement for
the fourth,  fifth and sixth years will not be less than 80% of the total amount
paid by  Bridge  and its  subsidiaries  for  Internet  protocol  data  transport
services;  and the amount paid to us under the agreement for the seventh through
tenth years will not be less than 60% of the total amount paid by Bridge and its
subsidiaries for Internet protocol data transport services.


     In  addition  we charge  Bridge for  additional  bandwidth  and  additional
connections at a rate  established on an annual basis.  In those instances where
the addition is outside of the existing network,  we will negotiate the terms of
the expansion  with Bridge on a  case-by-case  basis,  including any  additional
charges to be paid to us by Bridge to defray the cost of such  expansion.  If we
cannot  reach  agreement  with  Bridge on the annual  rate or on the  additional
charges,  and Bridge still desires for us to provide such service,  then we will
submit prices to an  independent  arbitrator who will assign the price quoted by
the party that in the arbitrator's opinion came closest to quoting a fair market
price.


     We have also agreed  that,  beginning  twelve  months after the date of the
transfer of the network,  the network will perform in  accordance  with specific
quality of service  standards.  If those standards are not met with respect to a
customer site in any month, Bridge will be entitled to receive,  upon request, a
credit for one  month's  charges  for that site.  The  Bridge  network  services
agreement  contains  quality of service  levels and  provides for credits if the
levels are not maintained.  In addition, a material breach of the service levels
allows  Bridge to terminate the  agreement  and/or  collect up to $50 million as
liquidated damages not more than once in any 36-month period.


     The agreement  provides for the creation of a strategic  advisory committee
comprised  of three of our  senior  executives  and three from  Bridge,  with an
additional  outside  consultant to be appointed by both parties.  The mission of
the committee will be to review the  performance  of the network,  to serve as a
forum for the consideration and discussion of issues related to the network, and
to discuss  issues related to the future  development of the SAVVIS  ProActiveSM
Network in the context of the relationship of SAVVIS and Bridge.  We have agreed
to  use  our   commercially   reasonable   best   efforts  to  comply  with  the
recommendations of the committee.


     Bridge has agreed that during the term of the  network  services  agreement
and for the next five years after the termination of this agreement, Bridge will
not compete  with us anywhere in the world in  providing  packet-data  transport
network  services,  other than  investments in a competitor not to exceed 10% of
the outstanding capital stock of that competitor.


     So long as Bridge is the beneficial owner of 20% of our outstanding  voting
securities, we have agreed not to provide any of our stockholders with voting or
registration  rights  superior  to the voting or  registration  rights of Bridge
other than as required by law.


     Local Network Services Agreement.  In most jurisdictions outside the United
States,  the charges that we pay for the local circuit between our  distribution
frame,   which   usually  is   located   in  a  central   office  of  the  local
telecommunications  provider,  and the Bridge customer premises are charged back
to Bridge at a rate intended to recover our costs.


                                       57

     Equipment  Colocation  Permits.  Some of the purchased  network  assets are
located in premises  currently leased by Bridge. The permits provide us, subject
to the  receipt of  required  landlord  consents,  with the  ability to keep the
equipment  that is being  purchased  from Bridge in the facilities in which they
are currently located. We have no interest in or rights to the real estate other
than the  right to enter the  facilities  for the  purpose  of  maintaining  the
equipment and to place a rack with equipment in the premises.  According to this
arrangement, we occupy a minimal amount of space, generally less than 100 square
feet, in each of the premises.  The permits,  approximately thirty in total, are
for a term that is coterminous  with the  underlying  rights which Bridge has to
such  facilities,  which  range  from one to ten  years.  Our  costs  for  these
colocation permits, which are fixed costs, are estimated to be less than $75,000
per year.

     Technical Services Agreement. Pursuant to the technical services agreement,
Bridge  provides us with services,  including  help desk support,  installation,
maintenance  and  repair  of  equipment,   customer  related  services  such  as
processing service orders and provisioning interconnection.  In addition, Bridge
manages  the  colocation  of  third-party  equipment  in our  facilities,  which
includes  facilities  management,  such as  power,  heating,  air  conditioning,
lighting and other  utilities and  installation,  monitoring and  maintenance of
equipment.  Bridge manages our network  operation  centers.  This agreement will
remain in effect so long as the network services  agreement is in effect.  Rates
for the services  provided under this agreement are fixed for the first year. We
expect the aggregate amount of payments to Bridge under the technical  services,
agreement in 2000 will be approximately  $1.1 million.  After the first year, we
will negotiate new rates,  and if we and Bridge cannot agree on new rates,  then
we will submit  prices to an  independent  arbitrator  who will assign the price
quoted by the party that in the arbitrator's  opinion comes closest to quoting a
fair market price.  Bridge is required to meet quality of service  standards set
forth in the agreement,  and, if Bridge fails to meet the standards,  we will be
entitled to a refund of all amounts paid for the non-complying  service plus the
costs we incurred to have that service provided by a third party.

     Administrative  Services  Agreement.  Until February 2003, and from then on
from year to year  until  Bridge or we  terminate  the  agreement,  Bridge  will
provide  us  with  various  administrative   services,   including  payroll  and
accounting  functions,  benefit management and the provision of office space. We
have  the  right  to take  over  one or  more  of  these  functions  before  the
termination of the  agreement.  Bridge charges us for these services in a manner
that is  intended  to  permit  Bridge to  recover  the  costs of  providing  the
services.

     GECC  Sublease.  We have  subleased  from Bridge some of the network assets
that Bridge leases from GECC.  The aggregate  amount of these capital  leases is
$25 million. The terms of the GECC sublease mirror the GECC master lease. At the
end of the lease term,  Bridge will have the right to acquire  these assets from
GECC for $1, and we will have the right to acquire  these assets from Bridge for
$1.

     On February 7, 2000, we entered into a registration  rights  agreement with
Welsh  Carson and  Bridge,  pursuant  to which we have  granted to Welsh  Carson
customary  registration  rights with  respect to the shares of our common  stock
which were  purchased by Welsh Carson from Bridge  following the initial  public
offering,  including  demand  registration  rights and  piggy-back  registration
rights.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors of
SAVVIS Communications Corporation:

We  have  audited  the  accompanying   consolidated   balance  sheet  of  SAVVIS
Communications  Corporation  and  subsidiaries  (the "Company" or the "Successor
Company"),  a  majority-owned  consolidated  subsidiary  of  Bridge  Information
Systems, Inc. ("Bridge"),  as of December 31, 1999, and the related consolidated
statements of operations,  changes in  stockholders'  deficit and cash flows for
the period from April 7, 1999 (the date of the Company's  acquisition by Bridge)
through December 31, 1999. We have also audited the  consolidated  balance sheet
of the Company's predecessor (the "Predecessor Company") as of December 31, 1998
and the related consolidated statements of operations,  changes in stockholders'
deficit and cash flows for the year then ended and for the period  from  January
1, 1999 through April 6, 1999. These financial statements are the responsibility
of the Successor and Predecessor Companies' management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the  United  States of  America.  Those  standards  require  that we plan and
perform the audit to obtain  reasonable  assurance  about  whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion, such consolidated financial statements referred to above present
fairly,   in  all  material   respects,   the   financial   position  of  SAVVIS
Communications  Corporation  and  subsidiaries  as of December  31, 1999 and the
results of their  operations  and their cash flows for the period  from April 7,
1999  through  December  31,  1999  in  conformity  with  accounting  principles
generally accepted in the United States of America. Further, in our opinion, the
Predecessor  Company's  consolidated  financial  statements  referred  to  above
present fairly, in all material respects,  their consolidated financial position
as of December 31, 1998 and the results of their operations and their cash flows
for the year ended  December  31, 1998 and for the period  from  January 1, 1999
through  April 6, 1999,  in  conformity  with  accounting  principles  generally
accepted in the United States of America.

As discussed in Note 1 to the consolidated  financial statements,  the Successor
Company  adopted a new accounting  basis  effective  April 7, 1999 in connection
with a change in  ownership  and  recorded net assets as of that date at the new
owner's acquisition cost. Accordingly,  the book value of assets and liabilities
and related  depreciation and amortization charges reflected in the accompanying
consolidated  balance  sheet  as of  December  31,  1999  and  the  consolidated
statement of operations  for the period from April 7, 1999 through  December 31,
1999 are not comparable to those of earlier periods presented.

INDEPENDENT AUDITORS' REPORT

Board of Directors of

SAVVIS Communications Corporation:

We have audited the accompanying consolidated statements of operations,  changes
in stockholders' deficit and cash flows of SAVVIS Communications Corporation and
subsidiaries  (the  "Company"),  for the year ended  December  31,  1997.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audit.

We conducted our audit in accordance with auditing standards  generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable  assurance about whether the financial  statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting  the amounts and  disclosures in the financial  statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audit  provides a  reasonable  basis for our
opinion.

In our opinion,  such consolidated  financial  statements present fairly, in all
material  respects,   the  results  of  operations  and  cash  flows  of  SAVVIS
Communications Corporation and subsidiaries for the year ended December 31, 1997
in  conformity  with  accounting  principles  generally  accepted  in the United
States.

The  accompanying  financial  statements  referred  to above have been  prepared
assuming the Company will continue as a going concern.  The Company has incurred
operating  losses and has a working capital  deficiency.  These conditions raise
substantial  doubt about the Company's  ability to continue as a going  concern.
The financial  statements do not include any adjustments to reflect the possible
future effects on the recoverability and classification of assets or the amounts
and  classification  of  liabilities  that may result  from the  outcome of this
uncertainty.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

             YEARS ENDED DECEMBER 31, 1997 AND 1998 (PREDECESSOR),
        PERIOD FROM JANUARY 1, 1999 THROUGH APRIL 6, 1999 (PREDECESSOR)
      AND PERIOD FROM APRIL 7, 1999 THROUGH DECEMBER 31, 1999 (SUCCESSOR)

               (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)


1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


ORGANIZATION  AND  BUSINESS  -- SAVVIS  Communications  Corporation,  a Delaware
corporation,  formerly SAVVIS Holdings Corporation  ("Holdings"),  together with
its wholly  owned  subsidiary,  SAVVIS  Communications  Corporation,  a Missouri
corporation  ("SCC"),  and  its  predecessor  company,   SAVVIS   Communications
Enterprises  L.L.C.   ("LLC"),  are  referred  to  herein  collectively  as  the
"Company".  The  Company  was  formed in  November  1995,  commenced  commercial
operations in 1996 and provides  high-speed Internet access and high-end private
Intranet services to corporations throughout the United States. The Company also
offers  colocation  services,   network  operations,   and  related  engineering
services.


On April 7, 1999  (the  "acquisition  date"),  the  Company  was  acquired  by a
wholly-owned subsidiary of Bridge Information Systems, Inc. ("Bridge") in an all
stock  transaction  that was  accounted  for as a "purchase  transaction"  under
Accounting  Principles  Board  Opinion  No.  16.  Pursuant  to the  terms of the
transaction,  Bridge issued  approximately  3,011,000 shares of its common stock
together  with 239,000  options and warrants to purchase  its common  stock,  in
exchange  for all the  outstanding  equity  interests  of SAVVIS.  To effect the
transaction,  the  Series  A,  B and C  Preferred  Shareholders  received  their
respective  liquidation  preferences  (see Note 3) in the form of Bridge  common
stock.  The Company's Series C warrant holders also exercised their warrants and
participated  with the other common  shareholders and employee option holders in
exchanging  their common shares for remaining  Bridge  common  shares.  Series A
warrant  holders  and those  holding  common  warrants  with a strike  price per
warrant of $4.13 exchanged their warrants for warrants to purchase Bridge common
stock.  Company stock options  outstanding at the date of the  transaction  were
converted into options to purchase Bridge common stock.


The value of the Bridge  shares and  options  issued and the costs  incurred  by
Bridge in connection with the acquisition aggregated $31,746. In accordance with
the accounting requirements of the Securities and Exchange Commission,  purchase
transactions  that result in one entity becoming  substantially  wholly-owned by
the  acquirer  establish  a new basis of  accounting  in the  acquired  entity's
records for the purchased assets and  liabilities.  Thus, the purchase price has
been allocated to the underlying assets purchased and liabilities  assumed based
on their  estimated  fair  values at the  acquisition  date.  As a result of the
application of fair value accounting,  intangibles,  goodwill, other liabilities
and  additional  paid-in  capital were  increased in the Company's  consolidated
financial statements.


The following is a summary of unaudited pro forma results of operations assuming
the acquisition had occurred at the beginning of the periods presented.

                        SAVVIS COMMUNICATIONS CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

PRINCIPLES OF CONSOLIDATION -- The consolidated financial statements include the
accounts of the  Company and its  wholly-owned  subsidiaries.  All  intercompany
balances and transactions have been eliminated in consolidation

CASH AND CASH  EQUIVALENTS -- All highly liquid  investments  with a maturity of
three months or less are considered to be cash equivalents.

PROPERTY  AND  EQUIPMENT  -- Property  and  equipment  are  recorded at cost and
depreciated using the straight-line  method over estimated useful lives of three
to five years.  Leasehold  improvements  are amortized over the shorter of their
estimated useful lives or the term of the related lease.

OTHER ASSETS -- Other current assets consists primarily amounts due from vendors
and  employees.  Other  long-term  assets  consists  primarily of deferred costs
associated  with the  Company's  initial  public  offering  and the  transfer of
network assets from Bridge, along with deposits for network services.

EQUIPMENT  UNDER  CAPITAL  LEASES  -- The  Company  leases  certain  of its data
communications  equipment and other fixed assets under capital lease agreements.
The assets and  liabilities  under capital  leases are recorded at the lesser of
the  present  value  of  aggregate  future  minimum  lease  payments,  including
estimated bargain purchase options, or the fair value of the assets under lease.
Assets under these capital  leases are  amortized  over the terms of the leases,
which are generally three years.

GOODWILL AND INTANGIBLE  ASSETS -- Goodwill is being  amortized over three years
and  intangible  assets  over one to three  years,  all using the  straight-line
method. The goodwill life was determined at the acquisition date based on market
and industry factors.

LONG-LIVED ASSETS -- The Company periodically evaluates the net realizable value
of long--lived assets,  including  intangible assets,  goodwill and property and
equipment,  relying on a number of factors including operating results, business
plans,  economic projections and anticipated future cash flows. An impairment in
the carrying value of an asset is recognized when the expected future  operating
cash flows to be derived  from the asset are less than its  carrying  value.  In
addition,  the Company's evaluation  considers  nonfinancial data such as market
trends,  product and  development  cycles,  and changes in  management's  market
emphasis.  As a result of such an evaluation of fixed assets,  during the period
from January 1, 1999 through April 6, 1999, the Company recognized an impairment
loss related to property and equipment of $1,383.

FAIR  VALUE OF  FINANCIAL  INSTRUMENTS  -- The  fair  value  of  borrowings  are
estimated by discounting the future cash flows using borrowing rates for similar
arrangements with similar maturities. As of December 31, 1998 and 1999, the fair
value of all borrowings  approximates  their carrying value. The carrying values
of cash, accounts receivable and accounts payable approximate their fair values.

STOCK SPLIT -- On July 22, 1999, the Board of Directors of the Company  declared
a 72,000-for-1 stock split on the Company's shares of common stock. As a result,
the Company had 125 million  shares  authorized,  72 million  shares  issued and
outstanding with a $.01 par value for each share of common stock. All references
to shares, options and warrants outstanding have been adjusted retroactively for
this stock split.

REVENUE  RECOGNITION AND DEFERRED REVENUE -- Service revenues consist  primarily
of Internet access service fees, which are fixed monthly amounts.  Services were
billed one month in advance  during 1997. For all periods,  any services  billed
and payments  received in advance of providing  services are deferred  until the
period such services are earned.  Equipment sales and  installation  charges are
recognized when equipment is delivered and installation is completed.

ADVERTISING COSTS -- Advertising costs are expensed as incurred.

INCOME TAXES -- Income  taxes are  accounted  for under the asset and  liability
method,  which  provides  for the  establishment  of  deferred  tax  assets  and
liabilities  for  the net tax  effects  of  temporary  differences  between  the
carrying amounts of assets and liabilities for financial  reporting purposes and
for income tax


                                       F-9

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED )

purposes.  The net operating  losses  generated by the Company during the period
between  April 7, 1999 and  September  10, 1999 may be utilized by Bridge in its
consolidated  tax return.  The income tax  accounts are stated as if the company
filed a separate  income tax return,  which is  consistent  with the tax sharing
agreement between the Company and Bridge.

EMPLOYEE  STOCK  OPTIONS -- The Company  accounts for employee  stock options in
accordance with Accounting Principles Board (APB) Opinion No. 25, Accounting for
Stock Issued to Employees. Under APB No. 25, the Company recognizes compensation
cost based on the intrinsic value of the equity instrument awarded as determined
at grant date.  The Company is also  subject to  disclosure  requirements  under
Statement of Financial  Accounting  Standards  ("SFAS") No. 123,  Accounting for
Stock-Based  Compensation  which  requires pro forma  information as if the fair
value method prescribed by SFAS No. 123 had been applied (see Note 7).

COMPREHENSIVE INCOME -- The Company has reported no items of other comprehensive
income under the  provisions of SFAS No. 130,  Reporting  Comprehensive  Income,
during the years ended  December  31, 1997 and 1998,  the period from January 1,
1999 through  April 6, 1999 and the period from April 7, 1999  through  December
31, 1999.

EARNINGS  (LOSS) PER SHARE -- All loss per share  amounts for all  periods  have
been  presented to conform to the  provisions of SFAS No. 128. All stock options
and warrants  outstanding  have been excluded from the  computations  of diluted
loss per share, as their effect would be antidilutive, and accordingly, there is
no  reconciliation  between  basic and  diluted  loss per share for the  periods
presented.  Also excluded from the  computations  are shares of restricted stock
subject to repurchase.

CONCENTRATIONS OF CREDIT RISK -- Financial  instruments that potentially subject
the Company to  concentrations  of credit risk consist  principally  of accounts
receivable. The Company periodically reviews the credit quality of its customers
and generally does not require collateral.

START-UP COSTS -- In accordance with the American  Institute of Certified Public
Accountants  Statement  of  Position  98-5,  Reporting  on the Costs of Start-Up
Activities,  the Company expenses start-up  activities and organization costs as
incurred.

USE OF ESTIMATES -- The  preparation of financial  statements in conformity with
generally accepted  accounting  principles requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

NEW ACCOUNTING  STANDARDS -- In June 1998, FASB issued SFAS No. 133,  Accounting
for Derivative Instruments and Hedging Activities,  which established accounting
and reporting standards for derivative instruments and hedging activities.  SFAS
No. 133 was amended by SFAS No. 137,  which delayed the  effective  date of SFAS
No. 133 to fiscal years and quarters beginning after June 15, 2000. SFAS No. 133
requires  that  an  entity   recognize  all  derivatives  as  either  assets  or
liabilities  in the  statement of financial  position and that it measure  those
instruments at fair value. The Company is assessing the requirements of SFAS No.
133 and the effects,  if any, on the Company's  financial  position,  results of
operations and cash flows.

RECLASSIFICATIONS  -- Certain 1997 and 1998 information has been reclassified to
conform to the 1999 presentation.

2. CORPORATE REORGANIZATION AND FINANCIAL TRANSACTIONS

The Company was  originally  organized in November  1995 and operated as SCC. In
1996,  SCC issued  46,996 shares of Series A  convertible  preferred  stock at a
price of $10.64 per share. In conjunction with the issuance, 175,047 warrants to
purchase  Series A preferred  stock were  issued.  The  warrants had an exercise
period of five  years  from the date of issue at an  exercise  price of  $10.64,
which approximated the market value of the stock at the date of issuance.


                                      F-10
<PAGE>

                        SAVVIS COMMUNICATIONS CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED )

Between February 7 and July 31, 1997, SCC issued  convertible notes to investors
with  principal  amounts  totaling  $3,700.  These  notes,  along  with  a  $500
convertible  note issued in 1996,  plus accrued  interest,  were  converted into
409,736 shares of Series A convertible  preferred stock at a price of $10.64 per
share on July 31,  1997.  The 175,047  warrants  to purchase  Series A preferred
stock were canceled upon conversion of the notes.

On July 31, 1997,  SCC formed the LLC,  which then  functioned  as SCC's primary
operating  entity  until it was merged back into the Company on April 30,  1998.
Ownership of the LLC was split  between  Class B shares,  of which SCC owned all
8,750,000  shares,  and Class A shares,  of which the LLC's  senior  convertible
promissory  noteholders  owned all 5,400,000  shares.  Both classes of stock had
equal voting rights and liquidation preferences.

On July 31, 1997, the LLC issued senior  convertible  notes (senior notes) in an
aggregate  principal amount of $5,400.  The senior noteholders also received 5.4
million Class A shares of the LLC for an aggregate nominal fee of $1. The senior
notes were unsecured, accrued interest at a rate of 8% per annum, and had a term
of five years.

Between  October 31 and  December  31,  1997,  LLC  entered  into the  following
transactions:

o Issued $3,100 in senior convertible bridge notes ("senior bridge notes").

o Issued  13,799,812  five-year  detachable  warrants  in  conjunction  with the
  issuance  of  the  senior  bridge  notes.   (See  discussion  below  regarding
  subsequent exchange.)

oIssued  23,496  shares of Series A  convertible  preferred  stock at a price of
 $10.64 per share.

During 1998 an  additional  $1,800 of LLC senior  bridge notes were  issued.  On
March 3, 1998, the Company's owners formed Holdings.  Holdings then entered into
the following transactions:

o Issued 502,410 shares of Series A Preferred  Stock in Holdings in exchange for
  all outstanding  Series A Preferred Stock of SCC (480,228 shares) plus accrued
  dividends.

o Issued  15,000  warrants to purchase  Series A Preferred  Stock of Holdings at
  $10.64 per share in exchange for an equal  amount of Series A Preferred  Stock
  Warrants of SCC with the same strike price.

o Converted  $5,400 in senior  notes and accrued  interest of $249 to  5,649,241
  Class B  shares  of the  LLC.  These  Class B  shares  were  then  immediately
  exchanged  for an equal  number  of  shares  of  Series B  Preferred  Stock in
  Holdings. In conjunction with the transaction,  the 5.4 million Class A shares
  of the LLC were cancelled.

o Issued 63,488,349 shares of $.001 par common stock of Holdings in exchange for
  all of the $.01 par common stock of SCC.

o Issued 22 million shares of Class C Preferred Stock and 299,466,125 detachable
  Series C common stock warrants of Holdings in exchange for $18,200 in cash and
  $3,800 of LLC senior  bridge  notes.  The  remaining  senior bridge notes were
  repaid from the proceeds of the financing.

o Issued 13,799,812  warrants to purchase common stock at a strike price of $.10
  in exchange  for an equal  amount of warrants to purchase  common stock of SCC
  with the same strike price.


On July 1,  1998,  Holdings  issued  additional  8  million  shares  of Series C
Preferred Stock and 108,896,798  detachable  common stock warrants for $8,000 in
cash.


The Company, based on an independent valuation,  assigned $3,700 to the value of
the detachable  Series C common stock warrants issued in the March 1998 and July
1998 transactions.  The $3,700 was recorded as a discount on the preferred stock
and an increase in additional  paid-in  capital.  Financing costs of $1,800 were
recorded as a discount against the preferred stock.  This resulted in $24,600 of
value being assigned


                                      F-11

                        SAVVIS COMMUNICATIONS CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

to the Series C Preferred Stock, with the difference  between such value and the
$30,000 redemption value being amortized through the mandatory  redemption date.
Amortization  was  charged  to  accumulated  deficit  until  the  April 7,  1999
acquisition by Bridge.

The conversion of the $5,400 in senior notes and the related exchange of Class B
shares  and  cancellation  of  Class A  shares  in March  1998  resulted  in the
recognition of an extraordinary gain on debt extinguishment and the recording of
the purchase of the minority interest.


3. REDEEMABLE PREFERRED STOCK AND STOCK WARRANTS

HOLDINGS SERIES A PREFERRED STOCK -- The Series A Preferred ranked junior to the
Series C Preferred  and the Series B Preferred,  but senior to all other classes
of stock as to  liquidation,  dividends,  redemption,  and any other  payment or
distribution  with respect to capital  stock.  The Series A Preferred  was to be
redeemed on December  31, 2003,  after (i) all shares of Series C Preferred  had
been  redeemed  by  payment  in  full  of the  aggregate  Series  C  liquidation

respect to capital stock.  The Series B Preferred was to be redeemed on December
31, 2003 after all shares of Series C Preferred  had been redeemed by payment in
full of the aggregate Series C liquidation preference.  The mandatory redemption
price for each  share of the  Series B  Preferred  was to be the  greater of the
Series B  liquidation  preference or the  then-applicable  fair market value per
share of the Series B Preferred.  At any time, holders of the Series B Preferred
were entitled to convert each share of Series B Preferred  into 13.3497 share of
common stock, subject to certain adjustments.  Each holder of Series B Preferred
was  required  to  convert  all of its  shares  of  Series B  Preferred,  at the
then--effective  Series B conversion  ratio, upon (i) the vote of 66 2/3 percent
of the then--outstanding shares of Series B Preferred and the Series A Preferred
(voting  together  as a  class)  or (ii)  upon  the  demand  of the  Company  in
connection with a public  offering.  Holders of Series B Preferred were entitled
to vote on all matters on which the common  stockholders  were entitled to vote.
Each share of Series B Preferred was entitled to  approximately  13.3497  votes.
The Series B Preferred holders were not entitled to dividends.

HOLDINGS SERIES C PREFERRED STOCK -- The Series C Preferred ranked senior to all
other classes of stock of the Company as to liquidation,  dividends, redemption,
and any other  payments and had a liquidation  preference  equal to the Series C

quarterly at 8 percent , and to the extent not paid in cash, such dividends were
added to the  liquidation  preference  of the Series C  Preferred.  The Series C
Preferred was to be redeemed on December 31, 2003 at a mandatory  price equal to
the liquidation preference. The Company was required, upon the demand of holders
of at least 25 percent of the outstanding  Series C Preferred,  to redeem all of
the Series C Preferred  upon a change of control,  failure to make any  required
dividend  payments,  or certain other conditions.  The Company had the option to
redeem the Series C Preferred in whole or in part upon ten business days' notice
for an amount equal to the liquidation preference.  Holders of Series C


                                      F-12
<PAGE>

                        SAVVIS COMMUNICATIONS CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED )

Preferred were entitled to vote on all matters on which the common  stockholders
were entitled to vote and were entitled to 13.6122 vote per share.  In addition,
the holders of 66 2/3 percent of the Series C Preferred  were  entitled to elect
four of the Company's seven directors.

See Note 1 for discussion of the redemption of all of the above  Preferred Stock
in connection with the acquisition of the Company by Bridge in April 1999.

SCC SERIES A PREFERRED  STOCK -- SCC Series A Preferred,  which was exchanged on
March 4, 1998 for Holdings  Series A Preferred  plus accrued  dividends,  ranked
senior  to all  other  then  outstanding  classes  of stock  as to  liquidation,
dividends,  redemption,  and any other payment or  distribution  with respect to
capital stock.  The Series A Preferred was to be redeemable  beginning  February
2002  and  continuing  through  2004  at the  mandatory  redemption  price.  The
mandatory redemption price for each share of the Series A Preferred was equal to
the greater of the Series A original issuance price or the fair market value per
share of the Series A Preferred,  plus accrued and unpaid  dividends.  Effective
August 1, 1997,  the terms of the Series A Preferred were amended to entitle the
holders  to a  dividend  rate of 8 percent  per annum on the  Original  Series A
Issuance Price.  Holders of the Series A Preferred were entitled to convert each
share of Series A  Preferred  into such  number of fully paid and  nonassessable
shares of common stock as determined by dividing the Original  Series A Issuance
Price  ($10.64)  by the  conversion  price of such series  (Series A  Conversion
Price) in effect at the time of  conversion.  The  initial  Series A  Conversion
Price per share was the  Original  Series A Issuance  Price,  subject to certain
adjustments.  Each holder of Series A Preferred  was  required to convert all of

ratio, upon (i) written consent of 70 percent of the then-outstanding  shares of
Series A Preferred or (ii) upon the demand of the Company in  connection  with a
public  offering.  Holders of Series A  Preferred  were  entitled to vote on all
matters on which the common  stockholders  were entitled to vote.  Each share of
Series A  Preferred  was  entitled to the number of votes equal to the number of

COMMON STOCK WARRANTS -- SCC issued 13,799,812 warrants to purchase common stock
at a strike  price of $.10 per warrant in October 1997 in  conjunction  with the
issuance of the senior bridge notes (Note 2). These  warrants were  subsequently
exchanged  for an equal amount of warrants to purchase  common stock of Holdings
with the same strike  price.  The  warrants  were to expire on the earlier of 10
years from the date of issuance or five years from the date of an initial public
offering.  These warrants were cancelled in connection  with the  acquisition of
the Company by Bridge in April 1999.

SERIES C WARRANTS -- In connection with the issuance of Series C Preferred Stock
in March and July of 1998, the Company issued 408,362,922 of detachable warrants
to purchase  common  stock of the Company for a price below $.01 per share.  The
warrants were assigned a value of $3,700.  The warrants were  exercisable at any
time except that no more than 75 percent of the warrants were exercisable  prior
to March 3, 2000.  The  warrants  were to expire 10 years from date of issuance.
The warrants provided,  subject to certain clawback provisions in the event of a
qualified public offering,  the Series C Preferred holders with 44.88 percent of
the common stock of the Company on a fully diluted  basis.  These  warrants were
cancelled in connection  with the  acquisition of the Company by Bridge in April
1999.

SERIES A WARRANTS -- SCC issued 15,000  warrants to purchase  Series A Preferred
shares of the Company for $10.64 per share to certain  investors and consultants
for  the  performance  of  services  on May  28,  1997.  These  warrants  vested
immediately.  Compensation  expense  recorded with respect to these warrants was
$160 in 1997. These warrants were subsequently exchanged for an identical number
of warrants to purchase Series A Preferred  shares of Holdings on March 4, 1998.
These  warrants were then  cancelled in connection  with the  acquisition of the
Company by Bridge in April 1999.

Effective January 1, 1998, the Company decreased the estimated  remaining useful
lives of its computer equipment, communications equipment and software from five
years to three years to more closely  reflect the actual  service  lives of such
equipment. The effect of the change was to increase depreciation expense and net
loss by approximately $486 for the year ended December 31, 1998.

Accumulated  amortization  for equipment  under capital leases for 1998 and 1999
was $831 and $1,361,  respectively.  Amortization  expense for 1997,  1998,  the
period  from  January 1, 1999 to April 6, 1999 and the period from April 7, 1999
to December 31, 1999 was $186, $814, $387 and $1,361, respectively.

7. EMPLOYEE STOCK OPTIONS

In January 1997, the Company established the 1997 stock option plan, under which
it was authorized to grant up to 19,757,596 of either incentive stock options or
non-qualified  stock  options to it  employees.  Options  under this plan became
exercisable over a three-year  vesting period from the date of grant and were to
expire ten years after the date of grant. The Company issued  8,087,100  options
under this plan during 1997.

Additionally,  on July 8, 1997, the Company granted an employee  790,304 options
to purchase the Company's  common stock at $.07 per share.  These options vested
immediately and had a ten-year life.

Effective  October  15,  1997,  the  Company's  Board of  Directors  amended and
restated  the 1997 stock option plan and  authorized  an  additional  15,072,319
options to be granted  under the plan. As part of this  amendment,  the Board of
Directors  authorized the existing  option holders to exchange their options for
incentive stock options priced at $.01 per share. These incentive options vested
6/48 six months from the employee's start date and then 1/48 monthly thereafter.
Accordingly,  options with respect to 9,228,655  shares of the Company's  common
stock were  canceled,  and new options with respect to the same number of shares
were granted with an exercise price of $.01 per share, the estimated fair market
value of the  Company's  common  stock at the  time.  An  additional  21,389,890
options  were also  granted  during  1997 under the same terms as the  incentive
options.  Two option  holders,  representing  238,356  options,  elected  not to
exchange,  and  accordingly,  these  options  remained  outstanding  under their
original  terms at the end of 1997.  Of these  options,  214,647 were  forfeited
during 1998.

In 1998,  the  Company's  Board of Directors  established  the 1998 stock option
plan,  under which it authorized  111,149,677  and granted  91,926,998  options.
These  options  vested on varying  bases over four years  beginning at the later
date of six months after the  employee's  start date or the grant date, and were
to expire 10 years from the grant date.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED )

In connection  with the Company's  acquisition on April 7, 1999, all outstanding
options under the plans were converted into 239,000  options to purchase  common
stock of Bridge.

On July 22, 1999,  the Company's  Board of Directors  adopted a new stock option
plan ("the 1999 Stock Option Plan") and authorized 8 million stock options to be
granted  under the plan.  On December 7, 1999,  an  additional  4 million  stock
options were authorized by the Board of Directors to be granted under this plan.
During the period from April 7, 1999  through  December  31,  1999,  the Company
granted  options to purchase  4,139,000  shares of its common  stock to selected
employees  of Bridge.  Also during the period,  the Company  granted  options to
purchase up to 4,409,508  shares of its common stock to its  employees.  Some of
these options contain  accelerated or immediate vesting  provisions,  and shares
issued  upon  exercise  of these  options  are  restricted  as to future sale or
subject to  repurchase.  During the period  from April 7, 1999 to  December  31,
1999,  the  Company  issued  4,477,287  shares of  restricted  stock  subject to
repurchase in connection with the exercise of these options.

The  Company has  elected to follow APB  Opinion  No. 25,  Accounting  for Stock
Issued to Employees ("APB 25") and related interpretations in accounting for its
employee stock compensation  plans. Under the provisions of APB 25, compensation
expense is recognized to the extent the value of the Company's stock exceeds the
exercise price of options or restricted stock at the date of grant.  During 1998
and the period from January 1, 1999 to April 6, 1999, the Company recognized $93
and $78,  respectively,  of  compensation  expense for option grants with strike
prices  that were below the value of the  Company's  stock.  Similarly,  for the
period April 7, 1999 to December 31, 1999, compensation expense in the amount of
$1.5 million was recognized related to option grants within the period.

Pro forma  information  regarding net income is required by SFAS No. 123 and has
been  determined as if the Company had accounted for its employee  stock options
under the fair value  method of SFAS No. 123.  The fair value of the options was
estimated  at the date of grant  using the  minimum  value  method.  Under  this
method, the expected volatility of the Company's common stock was not estimated,
as there was no market for the  Company's  common stock in which to monitor such
stock price volatility. The calculation of the fair value of the options granted
in 1997,  1998 and 1999 assumes a risk-free  interest  rate of 6.2 percent,  5.0
percent and 6.3 percent, respectively, an assumed dividend yield of zero, and an
expected life of the options of four years.  The weighted  average fair value of
options  granted  was  below  $.01 per  share in 1997,  1998 and for the  period
January 1 to April  6,1999.  For the period  April 7, 1999 to December 31, 1999,
the  weighted  average  fair value of options  granted was $6.51 per share.  For
purposes of pro forma  disclosures,  the estimated  fair value of the options is
amortized to expense over the options' vesting periods.

Had compensation cost for the Company's stock option plans above been determined
consistent  with the  provisions  of SFAS No. 123 based on the fair value at the
grant date, the Company's pro forma net loss would have been as follows:

</TABLE>

The weighted average remaining life of options  outstanding at December 31, 1999
was 9.74 years.

Included in the option grants  discussed  above,  during the period from October
through December 1999, the Company granted  2,843,258 stock options to employees
of  SAVVIS  and  Bridge  with an  exercise  price  of $.50  per  share.  Noncash
compensation  cost based upon the difference  between the exercise price and the
imputed  fair value of the  Company's  stock as of the  respective  option grant
dates totaling  approximately  $51,000 will be recorded over the vesting periods
of  such  options,  which  periods  range  from  immediate  up  to  four  years.
Approximately  $1,500 of noncash  compensation expense was recorded in December,
1999.


8. EMPLOYEE SAVINGS PROGRAM

The predecessor  Company  sponsored an employee savings plan that qualified as a
defined  contribution  arrangement  under Section 401(k) of the Internal Revenue
Code.  All  employees  were allowed to  contribute  a  percentage  of their base
salary,  subject to limitations.  The Company made no  contributions to the plan
during 1997,  1998 or 1999.  Effective  with the  acquisition  of the Company by
Bridge, the plan

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED )

administrator and investment  options were changed,  and the plan was amended to
incorporate  an  employer  matching  contribution  The  Company  matches  50% of
employee  contributions  up to a maximum  of 6% of total  compensation  or $2.4,
whichever is less. Company  contributions under this plan vest ratably over five
years, and totaled $154 for the period from April 7, 1999 to December 31, 1999.



9. INCOME TAXES

No income taxes were  provided  for the years ended  December 31, 1997 and 1998,
for the period  from  January  1, 1999 to April 6, 1999 or for the  period  from
April 7, 1999 to December  31,  1999,  as the  potential  deferred  tax benefit,
resulting  primarily  from the net  operating  losses,  was  fully  offset  by a
valuation allowance against such deferred tax benefit.

The components of deferred  income tax assets and  liabilities are as follows at
December 31:

</TABLE>

At December  31, 1998 and 1999,  the Company  recorded a valuation  allowance of
$11,294 and $16,217, respectively, against the net deferred tax asset due to the
uncertainty of its ultimate  realization.  The valuation  allowance increased by
$3,044 from  December 31, 1996 to December 31, 1997, by $8,042 from December 31,
1997 to December  31,  1998,  by $3,737 for the period  from  January 1, 1999 to
April 6, 1999,  and by $1,186 for the period from April 7, 1999 to December  31,
1999.

Section 382 of the  Internal  Revenue  Code  restricts  the  utilization  of net
operating  losses and other  carryover tax attributes  upon the occurrence of an
ownership change, as defined. Such an ownership change occurred during 1998 as a
result of the corporate  reorganization and financing transactions (see Note 2),
and again in 1999 as a result of the acquisition by Bridge.  Management believes
such limitation may restrict the Company's  ability to utilize the resulting net
operating losses over the 20-year carryforward period.

At December 31, 1999, the Company has  approximately $48 million in U.S. Federal
net  operating  loss  carryforwards  expiring  between  2011 and  2017.  The net
operating  losses  generated by the Company  during the period  between April 7,
1999 and  September 10, 1999 may be utilized by Bridge in its  consolidated  tax
return.

Rental expense under operating  leases for the years ended December 31, 1997 and
1998, was $1,924 and $1,905,  respectively,  and for the periods from January 1,
1999 through April 6, 1999 and from April 7, 1999 through  December 31, 1999 was
$630 and $1,922, respectively.

In February 2000,  the Company  entered into a ten and one-half year lease for a
new  headquarters  facility.  The rental cost  associated with this new facility
will  increase  the above  payments  and expense by an average of  approximately
$2,600 in 2000 and thereafter.

EMPLOYMENT  AGREEMENTS -- The Company has employment agreements with several key
executive  officers.  These  agreements  contain  provisions with regard to base
salary, bonus, stock options and other employee benefits.  These agreements also
provide for  severance  benefits  in the event of  employment  termination  or a
change in control of the Company.

In connection with the resignation of the Company's  President in November 1999,
the Company agreed to provide severance  benefits,  including  approximately one
year's base salary, a 1999 performance bonus of not less than 25 percent of base
salary, and other miscellaneous benefits. Approximately $360 was accrued in 1999
related to this severance arrangement.

LITIGATION  -- The  Company is subject to various  legal  proceedings  and other
actions arising in the normal course of its business.  While the results of such
proceedings and actions cannot be predicted,  management believes,  based on the
advice of legal  counsel,  that the  ultimate  outcome of such  proceedings  and
actions  will not have a  material  adverse  effect on the  Company's  financial
position, results of operations or cash flows.

Bridge funded the Company's  operations  during 1999. At December 31, 1999,  the
Company had amounts  payable to Bridge of $24,065.  See Note 14 for a discussion
of other relationships between the Company and Bridge arising from the execution
of  the  Master   Establishment  and  Transition  Agreement  and  other  related

13. SEGMENT INFORMATION

The Company has one reportable  operating segment. All of the company's revenues
are  derived  within the United  States,  and no revenue  arising  from a single
customer exceeded 10 percent of revenues in any period.


14. SUBSEQUENT EVENTS

PUBLIC OFFERING -- An initial public offering of the Company's  common stock was
completed  in  February  2000.  A total of 17  million  shares  were sold in the
offering,  14,875,000  shares sold by the Company and  2,125,000  shares sold by
Bridge,  all at $24 per share.  The  Company  received  net  proceeds  from this
offering of approximately  $333,000, of which approximately $127,000 was paid to
Bridge.  In  connection  with the  offering,  Bridge  also sold  certain  of its
holdings of the Company's stock to certain of Bridge's  stockholders.  After the
offering,  Bridge owned  approximately  49 percent of the Company's  outstanding
stock,  and  shareholders  of  Bridge  owned  approximately  26  percent  of the
Company's outstanding stock.

ASSET PURCHASE AND PREFERENTIAL DISTRIBUTION -- Simultaneous with the completion
of the public  offering,  the Company  purchased  or subleased  Bridge's  global
Internet  protocol  network  assets.  The  purchase  price  of  the  assets  was
approximately $88,000, of which approximately $63,000 was paid from the offering
proceeds.  The Company also paid a $58,000 preferential  distribution to Bridge.
Additionally,  the Company  assumed capital lease  obligations of  approximately
$25,000 related to these network assets.

Concurrent  with the asset  purchase,  the Company  also  entered into a 10-year
network  services  agreement  with Bridge  under which the Company  will provide
managed data networking services to Bridge. For the first year of the agreement,
the  Company's  fees will be based upon the cash cost to Bridge of operating the
network  as  configured  on the  date  the  Company  acquired  it,  and fees for
additional  services provided  following the closing of the transfer will be set
for a three-year term based on an agreed pricing schedule.  Bridge has agreed to
pay a minimum of  approximately  $105,000,  $132,000  and  $145,000  for network
services in 2000, 2001 and 2002, respectively.

                        SAVVIS COMMUNICATIONS CORPORATION

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED )

In  addition,  Bridge has agreed that the amount to be paid under the  agreement
for the  fourth,  fifth and sixth  years will not be less than 80 percent of the
total  amount paid by Bridge and its  subsidiaries  for Internet  protocol  data
transport  services;  and the  amount  to be paid  under the  agreement  for the
seventh through tenth years will not be less than 60 percent of the total amount
paid by  Bridge  and its  subsidiaries  for  Internet  protocol  data  transport
services.

Pursuant to a 10-year technical services agreement,  Bridge is providing various
services,  including technical support,  customer support and project management
in  the  areas  of  installation,   provisioning,  help  desk,  and  repair  and
maintenance.  In  addition,  Bridge  is  providing,  under  a  3-year  agreement
additional   administrative  and  operational  services,  such  as  payroll  and
accounting  functions,  benefit  management and office space,  until the Company
develops the capabilities to perform these services.

Some network assets to be purchased are located in premises  currently leased by
Bridge and are subject to an  equipment  colocation  permit  between  SAVVIS and
Bridge.  The  permits  provide the  Company,  subject to the receipt of required
landlord consents,  with the right to keep the equipment that is being purchased
from Bridge in the facilities in which they are currently located.  According to
this arrangement,  the Company will occupy a minimal amount of space,  generally
less than 100 square feet, in each of the  premises.  The permits are for a term
that is  coterminous  with  the  underlying  rights,  which  Bridge  has to such
facilities,  which  range  from  one to ten  years.  Costs  for this  space  are
estimated to be approximately $75 per year

                                 PURCHASE & SALE

         2.1 Purchase  and Sale of  Purchased  Assets;  Effective  Time.  On and
subject  to the  terms  and  conditions  of this  Agreement,  the  Buyer  hereby
purchases  from Seller (or shall cause the Buyer  Subsidiaries  to purchase from
the  appropriate  Seller  Subsidiaries),  and Seller  hereby  sells,  transfers,
conveys,  and delivers to the Buyer (or shall cause the Seller  Subsidiaries  to
sell, transfer,  convey and deliver to the appropriate Buyer Subsidiaries),  all
of the  Purchased  Assets at the  Closing  for the  consideration  specified  in
Section 2.3 hereof.  The Closing  shall be effective as of the close of business
on the day immediately preceding the Closing Date ("Effective Time");  provided,
however,  that the "Effective  Time" with respect to any Call Assets shall be as
provided in the respective Call Asset Transfer Agreement.

         2.2 Assumption of Liabilities.

         (a) On and subject to the terms and conditions of this  Agreement,  the
Buyer  hereby  assumes  and  becomes  responsible  for (or shall cause the Buyer
Subsidiaries  to  assume  and  become   responsible  for)  all  of  the  Assumed
Liabilities.

         (b) To the extent that Seller or any of the Seller  Subsidiaries  makes
payment on any Assumed Liabilities which are comprised of undisputed liabilities
for  payment of services  received  under the  Contracts,  then Buyer or a Buyer
Subsidiary  shall reimburse  Seller for such payment promptly upon receipt of an
appropriate  invoice from Seller.  Likewise,  to the extent that Buyer or any of
the Buyer  Subsidiaries  makes  payment on any  Retained  Liabilities  which are
comprised of undisputed  liabilities under the Contracts for payment of services
received under the Contracts, then Seller or a Seller Subsidiary shall reimburse
Buyer for such  payment  promptly  upon receipt of an  appropriate  invoice from
Buyer.

         2.3 Purchase Price. The Buyer agrees to pay to the Seller $119,863,759,
which shall be an amount equal to  $150,000,000,  less the net book value of all
the Call  Assets as of  October  31,  1999,  except for Call  Assets  located in
Europe, South Africa and the Middle East which shall be as of December 31, 1999,
less  the  repayment  of the  Japanese  subsidiary  loan  described  in the next
sentence of this  Section  2.3,  and less the net present  value of the sublease
payments to be made by Buyer related to the Leased Assets,  all of which amounts
are hereby agreed by the parties (the "Purchase  Price").  Simultaneous with, in
addition to, and in the same manner as the  foregoing  Purchase  Price  payment,
Buyer shall repay to Seller the intercompany  loans less cash balances of Bridge
Information  Systems  (Japan) KK, as of closing,  hereby agreed to be in the net
amount of $975,297.  The Purchase Price  allocable to the Interest shall be paid
partially  with  cash  and  partially  with  a  promissory   note  (the  "Note")
substantially  in the form attached hereto as Exhibit I. The cash portion of the
Purchase  Price is intended to be paid from the net  proceeds of the
initial public  offering by Buyer of its shares,  after payment of all costs and
expenses  of such  offering  including  fees  and  expenses  of  legal  counsel,
investment  bankers,  accountants and other  professionals  directly  engaged in
connection  with such  public  offering,  which  public  offering  is being made
simultaneously with the Closing ("Public Offering  Proceeds").  The cash portion
of the Purchase  Price shall be equal to an amount  determined

                                       7

<PAGE>


according to the following formula:  One Hundred Million Dollars  ($100,000,000)
of the first Three Hundred  Million  Dollars  ($300,000,000)  of Public Offering
Proceeds and 50% of the remaining  Public  Offering  Proceeds in excess of Three
Hundred Million ($300,000,000),  up to the full payment of the Purchase Price in
cash.  The  principal  amount of the Note shall be the Purchase  Price less this
cash payment.  The Purchase Price allocable to the International  Network Assets
shall be allocated first from this cash amount. The cash portion of the Purchase
Price  shall  be paid in the  manner  and by the  legal  entities  set  forth on
Schedule 2.3, or as otherwise agreed by the parties.

         2.4 The Closing.  The consummation of the transactions  contemplated by
this  Agreement  (the  "Closing")  shall take place at the offices of Bryan Cave
LLP, 245 Park Avenue,  New York, New York, or at such other place as the parties
may agree,  occurring  simultaneous  with the  consummation of the  transactions
contemplated by the Purchase Agreement among Buyer, Merrill Lynch & Co., Merrill
Lynch,  Pierce,  Fenner & Smith  Incorporated  and certain  other  underwriters,
relating to the initial public offering of shares of common stock of Buyer, such
Closing being deemed to have occurred immediately prior to the "Closing Time" as
defined in such Purchase Agreement ("Closing Date").

         2.5  Deliveries  at the Closing.  The Parties  shall make the following
deliveries at Closing:

         (a) The Seller  shall  execute and deliver to Buyer and the Buyer shall

(collectively,  the agreements  listed in (a)(i)  through  (a)(iv) are sometimes
referred to herein as the "Global Operative Agreements").

         (b) The Seller  shall  cause the  appropriate  Seller  Subsidiaries  to

         (c) Seller  and the Seller  Subsidiaries  shall have  delivered  to the
Buyer satisfactory  evidence of consent of Goldman Sachs and the participants in
Seller's lenders group, consent to sublease of the Leased Assets, and such other
consents to assignment of the Contracts (as described in Section 5.1 hereof) and
attainment of governmental approvals as Seller and the Seller Subsidiaries shall
have  received  as of the date  hereof.  To the  extent  Seller  and the  Seller
Subsidiaries  shall not have received such consents or  governmental  approvals,
the rights and obligations of the parties with respect thereto shall be governed
by Section 5.1 hereof.

         (d) The Buyer will deliver to the Seller, or Buyer will cause the Buyer
Subsidiaries  to deliver  to the  Seller  Subsidiaries,  the  Purchase  Price as
specified in Section 2.3 above.

         2.6 Purchase Price Allocation and Adjustment.

         (a) Subject to adjustment as provided in Section  2.6(b),  the Purchase
Price shall be allocated  among the  Purchased  Assets as follows:  The Purchase
Price allocable to the International Network Assets shall be equal to the sum of
the agreed upon US Dollar  value of such assets,  as set forth on Schedule  1.10
("Original Asset Value").  The Purchase Price allocable to the Interest shall be
equal to the difference  between the Purchase Price and the Original Value.  The
Parties believe that the allocations in this Section 2.6(a) reflect that most of
the fair value of the  Purchased  Assets is  contained  in the assets of the LLC
because of the positive cash flows generated by the US Network Assets.

         (b) Within fifteen days after the Closing, Seller shall update Schedule
1.10 and Schedule 1.16 attached  hereto to include all US Network Assets and all
International  Network Assets owned by Seller and the Seller  Subsidiaries as of
the  Effective  Time.  If the sum of the agreed upon value of the  International
Network  Assets shown on such revised  Schedule 1.10 (the "Revised Asset Value")
exceeds  the  Original  Asset  Value,  then the  amount  of the  Purchase  Price
allocable to the  International  Network Assets pursuant to Section 2.6(a) above
shall be  increased,  dollar for  dollar,  by such  excess and the amount of the
Purchase  Price  allocable  to the  Interest  shall be decreased by such excess.
Likewise, if the Revised Asset Value is less than the Original Asset Value, then
the amount of the Purchase Price allocable to the  International  Network Assets
pursuant to Section 2.6(a) above shall be decreased,  dollar for dollar, by such
amount and the amount of the Purchase  Price  allocable to the Interest shall be
increased by such amount.  In either event,  Seller shall  redistribute the cash
portion of the Purchase  Price paid by the Buyer  hereunder such that the Seller
Subsidiaries  are  compensated  for the  sale of  International  Network  Assets
entirely in cash. In the event  sufficient cash is not available in the Purchase
Price for this  purpose,  then the deficit  shall be funded by means of an early
prepayment under the Note.

                                   ARTICLE III
                    REPRESENTATIONS AND WARRANTIES OF SELLER

Interest upon any of the International  Network Assets or the US Network Assets,
and where any violation, conflict, breach, default,  acceleration,  termination,

adverse effect on the value or use of the International Network Assets or the US

title to, or a valid  leasehold  interest  in, the  Purchased  Assets and the US
Network Assets,  free and clear of all  Impermissible  Security  Interests,  and

aggregate,  have a material  adverse  affect on the  ability  of the  parties to
consummate the transactions contemplated by this Agreement, the Global Operative
Agreements  or the  Local  Operative  Agreements  or on the  value or use of the
International Network Assets or the US Network Assets.

         (c) Other  than (i) the  Assumed  Liabilities  incurred  by Seller  and
Seller  Subsidiaries in the ordinary course of business after December 31, 1999,
(ii) the Contracts,  and (iii) the Assumed  Liabilities  listed on Schedule 1.3,

passage of time or the giving of notice, or both, would constitute,  and neither
the  execution  of this  Agreement  nor  the  consummation  of the  transactions
contemplated hereby do or will constitute or result in, a breach or violation of
or default under any contract, or would cause the acceleration of any obligation
of any party thereto or the creation of any Impermissible Security Interest upon
any US Network Assets or International Network Assets.

         3.7  Employees.  Schedule 3.7 sets forth the names of all  employees of
the Seller who have been released by Seller or Seller  Subsidiaries for transfer

               ADDITIONAL AGREEMENTS AND COVENANTS OF THE PARTIES

         5.1 Notices and Consents.  Except as set forth on Schedule 5.1 attached
hereto, the Seller has given and obtained (or caused the Seller  Subsidiaries to
give or obtain) all third-party notices and consents and governmental  approvals
necessary to effect the purchase of the Purchased Assets and the assignment,  to
the extent a replacement  contract has not been  executed,  of the Contracts and
the assumption of the Assumed Liabilities  hereunder.  With respect to any third
party notices or consents or governmental  approvals that have not been given or
obtained  as of the  date  hereof,  Seller  covenants  and  agrees  to  use  its
reasonable  best efforts to give or obtain (or cause the Seller  Subsidiaries to
give or obtain) the same.  The Buyer agrees to fully  cooperate  with (and cause
the Buyer  Subsidiaries  to fully  cooperate  with) the  Seller  and the  Seller
Subsidiaries  in  such  efforts.  Until  such  time  as  Seller  or  the  Seller
Subsidiaries   shall  have  obtained  all  necessary  third  party  consents  to
assignment  by  Buyer  or the  Buyer  Subsidiaries  of  the  Contracts  and  the
assumption by the Buyer or the Buyer  Subsidiaries  of the Assumed  Liabilities,
Seller shall  continue (or shall cause the Seller  Subsidiaries  to continue) to
discharge and perform when due all obligations  associated therewith,  and Buyer
shall reimburse Seller for any expenses directly attributable thereto.

         5.2 Call Right. Seller, for itself and the Seller Subsidiaries,  hereby
grants to Buyer and the Buyer  Subsidiaries  the right to  purchase  (the  "Call
Right") the following assets ("Call Assets"):

         (a) in each of the  jurisdictions  set forth on Schedule  5.2(a) hereof
and such  other  jurisdictions  as Buyer  and  Seller  may,  from  time to time,
mutually agree (the "Call

                                       13

<PAGE>

Jurisdictions"),  all of the IP Network  assets  owned by the Seller  and/or the
Seller Subsidiaries in each Call Jurisdiction,  including those assets set forth
in Schedule 5.2(a), subject to additions and deletions subsequent to the Closing
permitted under the terms of this Agreement,  and all contract rights associated
therewith;  provided, for the purpose of clarification,  that telecommunications
circuits to destinations in any Call  Jurisdiction,  but originating  outside of
such Call  Jurisdiction,  shall not be Call Assets and instead shall be included
in the Acquired Network Facilities transferred hereunder at the initial Closing;
and

         (b) all the  rights  and  obligations  with  respect  to the  satellite
communications  agreements and all rights and obligations in specific  countries
with respect thereto, as described in Schedule 5.2(b),  subject to additions and
deletions subsequent to the Closing permitted under the terms of this Agreement,
(the "Satellite Rights").

Unless  earlier  terminated  pursuant to Section 5.6  hereunder,  the Call Right
granted  hereunder  shall  expire on the tenth  anniversary  of the date  hereof
("Expiration Date"); provided, however, that if the term of the Network Services
Agreement is extended beyond the Expiration Date, then the Expiration Date shall
be the date upon which the  Network  Services  Agreement,  attached as Exhibit A
hereto,  is  terminated.  Upon  the  exercise  of the  Call  Right  in any  Call
Jurisdiction  or with respect to the  Satellite  Rights,  Buyer shall assume all
liabilities and obligations of the Seller and/or the Seller Subsidiaries related
to the respective  Call Assets to the extent that such  liabilities  arise on or
after the date of exercise.

         5.3  Exercise  of Call  Right.  Buyer  shall  use its  reasonable  best
efforts, from and after the Closing, to secure the consents, licenses, and other
authorizations,  whether from governments or private  parties,  and to establish
such  foreign  legal  presence  and to  fulfill  such other  conditions,  as are
necessary  in order  to  permit  Buyer to  acquire  the Call  Assets;  provided,
however,  that this obligation shall not require that Buyer permit third parties
to own a portion of any  subsidiaries of Buyer unless Buyer otherwise  agrees to
such ownership.  Prior to the receipt of all such material  consents,  licenses,
and  authorizations  and the  establishment of any necessary  foreign  presence,
Buyer shall not be  obligated  to exercise the Call Right with respect to any or
all of the Call Jurisdictions or with respect to the Satellite Rights, nor shall
Buyer be obligated to exercise  all the Call Rights at one time;  rather,  Buyer
may  exercise the Call Right in each Call  Jurisdiction  and with respect to the
Satellite  Rights  separately,  from time to time,  and at any time prior to the
Expiration Date subject to the immediately following provision. Upon the receipt
of all material  consents,  licenses and authorizations and the establishment of
any necessary  foreign presence in any Call  Jurisdiction or with respect to all
the Satellite Rights connected with a particular third-party satellite contract,
Buyer shall be obligated to proceed  expeditiously with the exercise of the Call
Right with respect to such Call Jurisdiction or Satellite  Rights.  The exercise
price of the Call Right,  other than with respect to Satellite  Rights,  in each
Call  Jurisdiction  shall be $1.00 plus the net book value of the Call Assets in
the applicable Call Jurisdiction(s) on the effective date of the exercise of the
Call  Right for such Call  Jurisdiction.  The  exercise  of the Call  Right with
respect to the Satellite  Rights shall only be permitted if made with respect to
all Satellite Rights under a particular  global satellite  contract as set forth
on Schedule  5.2(b),  and the exercise  price shall be $1 plus the assumption of
all obligations of Seller with respect to such contract.  The exercise of a Call
right shall be effected by Buyer through the delivery of ten days written notice
to Seller.  The Call  Assets  shall be

                                       14

<PAGE>

transferred  via a Call  Asset  Transfer  Agreement  in  substantially  the form
attached as Exhibit J hereto. Upon the exercise of a Call Right, a Local Network
Services  Agreement for the respective Call  Jurisdiction  substantially  in the
form  of  Exhibit  G  attached  hereto,  or a  comparable  agreement  containing
substantially the same terms as a Local Network Services  Agreement with respect
to  Satellite  Rights  as  agreed  by  the  Parties,  will  be  executed  by the
appropriate Seller Subsidiaries and Buyer Subsidiaries.

         5.4 Seller's Obligation with Respect to Call Assets. Until the earliest
of (a) the  Expiration  Date,  (b) the date  upon  which no Call  Assets  remain
subject to the Call  Right,  or (c) the Call  Right is  terminated  pursuant  to
Section 5.6, and subject at all times to the rights and obligations set forth in
the Network Services  Agreement executed between the parties as of the same date
as the date of this Agreement:

         (a) Seller shall maintain and operate (or cause the Seller Subsidiaries
to  maintain  and  operate)  the Call  Assets in the same manner and to the same
extent  as  Seller  and the  Seller  Subsidiaries,  as the  case  may  be,  have
maintained  such assets to date.  Seller  shall take (and shall cause the Seller
Subsidiaries  to take) any and all actions  reasonably  necessary to fulfill its
obligations hereunder;

         (b) Seller shall not (nor shall it permit the Seller  Subsidiaries  to)
dispose of, encumber or otherwise  transfer any interest in, or amend,  waive or
modify any provision of or terminate  any Contract  relating to, the Call Assets
without  the  prior  written  consent  of  Buyer  which  consent  shall  not  be
unreasonably  withheld;  provided,  "unreasonable"  shall be determined from the
perspective  of Buyer and shall  include all  actions  which may have a material
adverse effect if Buyer were to exercise the related Call Right;

         (c) Seller shall  provide (and shall cause the Seller  Subsidiaries  to
provide)  Buyer with  notice of any events  that have,  or may have,  a material
adverse effect on the Call Assets or on Buyer's right or ability to exercise the
Call Right with respect to any of the Call Assets;

         (d) If Buyer chooses to exercise any Call Right prior to the receipt of
all  consents,  licenses  and  other  authorizations  or  establishment  of  the
appropriate  foreign legal presence,  it does so with the assumption of all risk
or other liability arising from such absence of necessary  consents,  license or
other authorizations or legal presence.  Upon exercise of any Call Right, Seller
shall use its  reasonable  best  efforts to obtain any  required  consent of any
other  contracting  parties  to the  assignment  or  novation  of any  agreement
pertaining to the  applicable  Call Assets,  and Buyer shall use its  reasonable
best  efforts  to assist  Seller in all such  endeavors.  Unless  and until such
consent  shall be  forthcoming  and any  relevant  agreements  shall  have  been
assigned or novated,  Buyer  shall at its own cost and expense  assume  Seller's
obligations under such agreements and Seller shall account to Buyer for all sums
received therefrom. Seller will at Buyer's request and expense give to Buyer all
assistance  in the  power  of  Seller  to  enable  Buyer to  enforce  any of the
agreements  so assigned  against  the other  contracting  party or parties  and,
without  prejudice to the  generality  of the  foregoing,  will provide all such
relevant books, documents and other information as Buyer may require in relation
thereto; and


                                       15

<PAGE>

         (e) Buyer shall have no rights to use the Call Assets prior to exercise
of the Call Rights, except as otherwise consented to by Seller, such consent not
to be unreasonably withheld.

         5.5 Buyer's  Obligations  with Respect to Call Assets.  With respect to
those  Call  Assets  in  the  Call  Jurisdictions  set  forth  on  Schedule  5.5
("Short-Term  Call  Assets"),  Buyer and Seller  expect the exercise of the Call
Right to occur  within the  calendar  year  2000.  Regardless  if such  exercise
actually occurs in 2000,  with respect to the Short-Term  Call Assets,  Buyer or
the Buyer Subsidiaries shall reimburse the Seller or the Seller Subsidiaries for
all costs  requiring an expenditure of cash which are directly  associated  with
the use, maintenance and operation of the Short-Term Call Assets, including, but
not limited to, maintenance of leased lines.  Seller shall invoice Buyer monthly
for such  costs.  Likewise,  Seller  shall  compensate  Buyer for the use of the
Short-Term  Call Assets  pursuant to such Network  Services  Agreement  executed
between  the  parties  as of the same date as the date of this  Agreement.  Such
obligations of Buyer and Seller shall run  concurrently and shall continue until
the Expiration Date, unless earlier  terminated by mutual agreement of Buyer and
Seller.  No similar  obligations  will exist for Buyer or Seller with respect to
the remaining  Call Assets prior to the exercise of the Call Rights with respect
thereto.

         5.6  Termination  of  Call  Right.   The  Call  Right  shall  terminate
automatically on the earlier of the Expiration Date or the date upon which Buyer
has  exercised  the Call Right in each of the Call  Jurisdictions.  Prior to the
Expiration  Date,  at any time and from  time to  time,  the Call  Right  may be
terminated with respect to any or all of the Call  Jurisdictions upon the mutual
agreement of the parties.

         5.7 Employee  Services.  From and after the Closing  until such time as
the Employees are transferred to the Buyer pursuant to Section 5.8, Seller shall
make all of the Employees  available to Buyer on a full-time basis.  Buyer shall
reimburse Seller, on a monthly basis, for all payroll costs directly  associated
with such Employees.

         5.8 Offers of Employment.

         (a) As of December  31,  1999,  Buyer has offered  employment  with the
Buyer to the  Employees,  and Seller has released  from their  employment  those
Employees  who  accepted  employment  with the Buyer to enable  them to commence
their employment with the Buyer.  Such Employees  commenced  employment with the
Buyer on January 1, 2000 (the "Employment Date").

         (b) Seller shall  furnish Buyer with all employee data files related to
the Employees. The Seller makes no representations or warranties concerning such
files, or the contents or sufficiency thereof.

         5.9 Employee Benefits.

         (a) Employees  shall continue to  participate in each Employee  Benefit
Plan  maintained by Seller until such time as Buyer  establishes and maintains a
substantially similar

                                       16

<PAGE>


Employee  Benefit Plan;  provided that, as of the  Employment  Date, an Employee
shall cease to be eligible to  participate  in the Bridge  Information  Systems,
Inc.  401(k)  Salary  Savings  Plan  ("Bridge  Plan") and shall be  eligible  to
participate in the Savvis  Communications  Co. 401(k) Plan ("Savvis  Plan"),  in
accordance  with the terms of  Section  5.9(b)  and  subject to the terms of the
Savvis Plan.  During the period in which Employees are participating in Seller's
Employee  Benefit  Plans,  Buyer shall  reimburse  Seller for any  employer-paid
amounts under such Employee Benefit Plans.

         (b) As soon as  practicable  after the  Employment  Date,  Seller shall
cause to be transferred  from the Bridge Plan to the Savvis Plan all Bridge Plan
assets  representing  account balances of Employees under the Bridge Plan. Buyer
and Seller  shall take all such  actions as are  necessary  to ensure  that such
transfer complies with all relevant  provisions of Section 411(d)(6) of the Code
and the regulations thereunder. Buyer shall amend the Savvis Plan, to the extent
necessary, to provide that each Employee is credited, for all purposes under the
Savvis Plan and subject to the other  provisions of such plan,  with all service
completed prior to the Employment Date with Seller.

         (c) Buyer shall assume the  obligations in connection  with accrued but
unused  vacation  and shall be  responsible  for  vacation  pay at and after the
Employment  Date  with  respect  to  service  (whether  prior  to or  after  the
Employment Date) of all Employees. Buyer shall afford Employees credit for their
period of  employment  with  Seller for  purposes of  determining  the amount of
vacation  to which the  Employees  are  entitled  each year and for  purposes of
determining all other seniority based benefits.

         (d) Buyer  and  Seller  acknowledge  and  agree  that the  transactions
contemplated  by this Agreement shall not constitute a termination of employment
of any Employee.

         (e) No provision of this Agreement,  including without  limitation this
Section 5.9, shall create any  third-party  beneficiary  rights in any person or
organization,   including  without  limitation  employees  or  former  employees
(including  any  beneficiary  or dependent  thereof) of Seller,  unions or other
representatives   of  such   employees   or  former   employees,   or  trustees,
administrators, participants, or beneficiaries of any Employee Benefit Plan, and
no provision of this  Agreement,  including  this Section 5.9, shall create such
third-party  beneficiary rights in any such person or organization in respect of
any benefits that may be provided,  directly or  indirectly,  under any Employee
Benefit Plan.

         (f) Seller and Buyer shall cooperate as may reasonably be required with
respect to each of the filings,  calculations,  and other  actions  necessary to
effect the  transactions  contemplated  by this Section 5.9 and in obtaining any
government approvals as may be required hereunder.

         5.10 Access to Employee  Information.  From and after the Closing,  the
parties  hereto  will  cooperate  with each other in the  administration  of any
applicable Employee Benefit Plans and programs.  To the extent permitted by law,
at the Employment Date or within a reasonable time  thereafter,  the Seller will
provide  the Buyer the  necessary  employee  data or copies  thereof,  including
personnel and benefit  information,  maintained with respect to the

                                       17

<PAGE>


Employees  by the Seller or by its  independent  contractors,  such as insurance
companies and actuaries.

         5.11 WARN Act Indemnification. The Buyer agrees to indemnify the Seller
and its directors, officers, employees,  consultants and agents for, and to hold
the  Seller  and its  directors,  officers,  employees,  consultants  and agents
harmless from and against,  any and all losses arising or resulting,  or alleged
to arise or result from the notification or other requirements of the WARN Act.

         5.12 Workers'  Compensation  Claims. The Seller will be responsible for
any workers'  compensation claims by any Employee for injuries incurred prior to
such Employee's  Employment Date. The Buyer will be responsible for any workers'
compensation  claims for  injuries  incurred  by any  Employee  on or after such
Employee's Employment Date.

         5.13  Employee  Benefit  Plans.  Except as  expressly  provided in this
Article V, the Buyer will not adopt, assume or otherwise become responsible for,
either  primarily or as a successor  employer,  any assets or liabilities of any
Employee Benefit Plans, arrangements, commitments or policies currently provided
by the  Seller or by any  member of its  controlled  group of  corporations.  In
addition,  the Buyer will not assume  Seller's  obligations  under Code  Section
4980B and ERISA Section 606 relating to  individuals  who are neither  Employees
nor  dependents  of  Employees.   Buyer  shall  be  responsible  for  satisfying
obligations   under  ERISA   Section  606  and  Code  Section  4980  to  provide
continuation  coverage to or with respect to any  Employees  with respect to any
"qualifying event" which occurs on or following the Employment Date.

         5.14 Further Assurances.  From and after Closing,  the parties shall do
such acts and  execute  such  documents  and  instruments  as may be  reasonably
required to make effective the transactions  contemplated  hereby.  In the event
that consents,  approvals,  other  authorizations  or other acts contemplated by
this  Agreement  have not been fully  effected as of Closing,  the parties  will
continue after Closing,  without further consideration,  to use their reasonable
best efforts to carry out such  transactions;  provided,  however,  in the event
that certain  approvals,  consents or other  necessary  documentation  cannot be
secured, then the party having legal responsibility,  ownership or control shall
act on behalf of the other party, without further  consideration,  to effect the
essential intention of the parties with respect to the transactions contemplated
by this Agreement.


                                   ARTICLE VI
                     REMEDIES FOR BREACHES OF THIS AGREEMENT

                                       18

<PAGE>

         (a) Subject to the  limitations  set forth in Section 6.2(c) below,  in
the  event  the  Seller  or  any   Seller   Subsidiary   breaches   any  of  its
representations, warranties, and covenants contained in this Agreement, provided
that the Buyer makes a written claim for indemnification against the Seller with
respect to its  representations  and warranties  within the survival  period set
forth in Section  6.1,  then the Seller  agrees to  indemnify  the Buyer and the
Buyer Subsidiaries from and against the entirety of any Adverse Consequences the
Buyer and the Buyer  Subsidiaries shall suffer through and after the date of the
claim for indemnification  (but excluding any Adverse  Consequences the Buyer or
the Buyer  Subsidiaries  shall suffer after the end of any  applicable  survival
period) caused proximately by the breach.

         (b)  Subject  to the  limitations  set forth in Section  6.2(c)  below,
Seller agrees to indemnify the Buyer and the Buyer Subsidiaries from and against
the entirety of any Adverse  Consequences  the Buyer and the Buyer  Subsidiaries
shall suffer  caused  proximately  by any  liability of the Seller or any Seller
Subsidiary which is a Retained Liability  (including any liability of the Seller
or any Seller  Subsidiary  that  becomes a  liability  of the Buyer or any Buyer
Subsidiary under any bulk transfer law of any jurisdiction, under any common law
doctrine of de facto merger or successor liability, or otherwise by operation of
law).

         (c) Notwithstanding anything to the contrary, (i) Seller shall not have
any liability under this Article VI in respect of any individual claim (or group
of related claims) unless such claim or group of related claims exceeds $25,000,
(ii) Seller shall not have any  liability  under this Article VI except and only
to the extent the aggregate of permitted  claims exceeds a deductible  amount of
$1,500,000,  and (iii) Seller's aggregate  liability under this Article VI shall

         (d) Without  limitation,  Seller  agrees to indemnify the Buyer and the
Buyer Subsidiaries from and against the entirety of any Adverse Consequences the
Buyer  and  the  Buyer  Subsidiaries  shall  suffer  caused  proximately  by any
liability or obligation of the Seller or any Seller  Subsidiary which relates to
data,  information,  or other  content  which has been,  or  should  have  been,
delivered  by the  Seller  or any  Seller  Subsidiaries  to Buyer  or any  Buyer
Subsidiaries for transmission over the IP Network.

         6.3 Indemnification Provisions for Benefit of Seller.

         (a) In the event the Buyer or any Buyer Subsidiary  breaches any of its
representations, warranties, and covenants contained in this Agreement, provided
that the Seller  makes a written  claim for  indemnification  against  the Buyer
within the survival period with respect to its  representations  and warranties,
then the Buyer agrees to indemnify the Seller and the Seller  Subsidiaries  from
and against the entirety of any Adverse  Consequences  the Seller and the Seller
Subsidiaries  shall  suffer  through  and  after  the  date  of  the  claim  for
indemnification  (but  excluding  any  Adverse  Consequences  the Seller and the
Seller  Subsidiaries  shall  suffer  after  the end of any  applicable  survival
period) caused proximately by the breach.

                                       19

<PAGE>

         (b) Buyer  agrees to indemnify  the Seller and the Seller  Subsidiaries
from and against the  entirety  of any Adverse  Consequences  the Seller and the
Seller  Subsidiaries  shall suffer  caused  proximately  by any liability of the
Buyer or any Buyer Subsidiary which is an Assumed Liability.


         6.4 Matters Involving Third Parties.

         (a) If any third party shall notify any party (the "Indemnified Party")
with  respect to any  matter (a "Third  Party  Claim")  which may give rise to a
claim for  indemnification  against the other party (the  "Indemnifying  Party")
under this Article VI, then the  Indemnified  Party shall  promptly  (and in any
event, if the matter concerns a legal proceeding,  within 15 business days after
receiving notice of the Third Party Claim, and with respect to any other matter,
within 30 business days) notify the Indemnifying Party thereof in writing.

         (b) The  Indemnifying  Party  will have the right at any time to assume
and thereafter  conduct the defense of the Third Party Claim with counsel of its
choice reasonably satisfactory to the Indemnified Party; provided, however, that

             (i)  if the  Third  Party  Claim  falls  within  the  scope  of the
         indemnification set forth in Section 6.2(d), then the Indemnified Party
         shall have the right to refuse to accept such  assumption of defense by
         Indemnifying Party unless and until such time as the Indemnifying Party
         shall provide to the  Indemnified  Party such assurances of payment and
         performance of such  indemnification  obligation as shall be reasonably
         satisfactory to the Indemnified Party; and

             (ii) the  Indemnifying  Party will not  consent to the entry of any
         judgment or enter into any  settlement  with respect to the Third Party
         Claim without the prior written consent of the  Indemnified  Party (not
         to be withheld unreasonably) unless the judgment or proposed settlement
         involves  only the  payment  of money  damages  and does not  impose an
         injunction or other equitable relief upon the Indemnified Party.

         (c) Unless and until the Indemnifying  Party assumes the defense of the
Third Party Claim as provided in Section 6.4(b) above,  however, the Indemnified
Party may defend  against the Third Party Claim in any manner it reasonably  may
deem appropriate,  including,  without  limitation,  consent to the entry of any
judgment or enter into any settlement with respect to the Third Party Claim.

         6.5 Call Right Remedies. The parties agree that the Call Assets and the
Call Right are unique interests and that, in the event of Seller's breach of its
obligations  with  respect to the Call Assets,  monetary  damages will not fully
compensate  Buyer.  Therefore,  the  parties  agree  that  Buyer  shall have the
remedies  which are  available to it for Seller's  breach or violation of any of
the provisions of this Agreement relating to the Call Assets, including, but not
limited to, the  equitable  remedies for  specific  performance  and  injunctive
relief.

                                       20

<PAGE>

         6.6 Exclusive  Remedy.  The Buyer and the Seller  acknowledge and agree
that,  subject to the other remedies granted to the Buyer in Section 6.5 hereof,
the  foregoing  indemnification  provisions  in this  Article  VI  shall  be the
exclusive  remedy of the Buyer and the Seller with  respect to the  transactions
contemplated by this Agreement.

                                   ARTICLE VII
                                  MISCELLANEOUS

         7.1 No Third-party  Beneficiaries.  This Agreement shall not confer any
rights or remedies  upon any Person other than the parties and their  respective
successors and permitted assigns.

         7.2 Entire Agreement. This Agreement (including the documents  referred
to herein)  constitutes the entire agreement  between the parties and supersedes
any prior  understandings,  agreements,  or  representations  by or between  the
parties,  written or oral,  to the extent they related in any way to the subject
matter hereof. To the extent any provisions of the documents referred to in this
Agreement, or executed in connection with the transactions  contemplated by this
Agreement,  are  inconsistent  with the provisions of this  Agreement,  then the
provisions of this  Agreement  shall  prevail,  both as to the parties and as to
their  respective  affiliates,  and the  parties  shall  take such  steps as are
appropriate to recognize such supremacy of this Agreement.

         7.3 Succession and Assignment. This Agreement shall be binding upon and
inure to the benefit of the parties named herein and their respective successors
and permitted  assigns.  No party may assign either this Agreement or any of its
rights,  interests,  or obligations hereunder without the prior written approval
of the other party, which consent shall not be unreasonably withheld;  provided,
however, Seller and Seller Subsidiaries shall have the right to grant a security
interest  or  mortgage  with  respect to, or make any  assignment  for  security
purposes  or pledge of,  Seller's  and Seller  Subsidiaries'  rights  under this
Agreement and any of the Global  Operative  Agreements  and the Local  Operative
Agreements,  to the extent  required by the senior  lending group of Seller as a
condition to granting the consent to the transaction contemplated hereby.

         7.4  Counterparts.  This  Agreement  may be  executed  in  one or  more
counterparts,  each of  which  shall  be  deemed  an  original  but all of which
together will constitute one and the same instrument.

         7.5  Headings.  The Section  headings  contained in this  Agreement are
inserted  for  convenience  only and shall not affect in any way the  meaning or
interpretation of this Agreement.

         7.6  Notices.  All  notices,  requests,   demands,  claims,  and  other
communications hereunder will be in writing. Any notice, request, demand, claim,

of any jurisdiction other than the State of Missouri.

         7.7 Arbitration.

         (a) The  parties  hereby  agree  to  submit  all  disputes  to rules of
arbitration of the American  Arbitration  Association  and the Missouri  Uniform
Arbitration  Act (the "Rules")  under the following  provisions,  which shall be
final and binding upon the parties,  their successors and assigns,  and that the
following  provisions  constitute a binding  arbitration clause under applicable
law. Either party may serve process or notice on the other in any arbitration or
litigation in accordance with the notice  provisions  hereof.  The parties agree
not to  disclose  any  information  regarding  any dispute or the conduct of any
arbitration  hereunder,   including  the  existence  of  such  dispute  or  such
arbitration,   to  any   person  or  entity   other  than  such   employees   or
representatives of such party as have a need to know.

         (b) Either  party may  commence  proceedings  hereunder  by delivery of
written notice  providing a reasonable  description of the dispute to the other,
including a reference to this provision (the "Dispute Notice"). Either party may
initiate  arbitration  of a  dispute  by  delivery  of a  demand  therefor  (the

                                       22

<PAGE>

arbitration shall be conducted in St. Louis, Missouri.

         (c) The  arbitration  shall  be  conducted  by three  arbitrators  (the
"Arbitrators"),  one of whom shall be selected by Seller,  one by Buyer, and the
third by agreement of the other two not later than 10 days after  appointment of
the first two, or, failing such agreement,  appointed  pursuant to the Rules. If
an  Arbitrator  becomes  unable to  serve,  a  successor  shall be  selected  or
appointed in the same manner in which the predecessor Arbitrator was appointed.

         (d) The arbitration  shall be conducted  pursuant to such procedures as
the parties may agree or, in the absence of or failing such agreement,  pursuant
to the Rules.  Notwithstanding the foregoing, each party shall have the right to
inspect the books and records of the other party that are reasonably  related to
the Dispute, and each party shall provide to the other, reasonably in advance of
any hearing, copies of all documents which such party intends to present in such
hearing and the names and addresses of all witnesses  whose testimony such party
intends to present in such hearing.

         (e) All hearings shall be conducted on an expedited  schedule,  and all

stenographic record thereof.

         (f) The  Arbitrators  shall  complete  all  hearings  not later than 90
calendar days after the Arbitrators' selection or appointment,  and shall make a

               Services.

         2.4   In addition to the Services provided under this Agreement,  it is
               expected that additional administrative services will be provided
               under  the  separate  Local  Administrative  Services  Agreements
               between   certain   SAVVIS   Subsidiaries   and  certain   Bridge

3.       RATES AND CHARGES
         SAVVIS shall pay Bridge for the Services at rates to be mutually agreed

         extent  contrary  to local law.  The  mutually  agreed  rates  shall be
         addressed by the parties in the manner set forth in Section 1.2. If the

               States  currency  within 30 days from the date of  receipt of the
               invoice.  All  amounts  not in dispute  are  subject to  interest
               charges of 1-1/2  percent  that will accrue  daily on all amounts
               not paid within 30 days of the date of receipt of the invoice.

         4.2.  SAVVIS shall pay any sales,  use,  value added,  federal  excise,
               utility, gross receipts, state and local surcharges,  and similar
               taxes,  charges or levies lawfully  levied by a duly  constituted
               taxing   authority   against  or  upon  the   Services.   In  the
               alternative,  SAVVIS  shall  provide  Bridge  with a  certificate
               evidencing  SAVVIS'  exemption  from payment of or liability  for
               such taxes.  As part of the Services,  Bridge will administer the
               payment of SAVVIS'  payroll taxes.  SAVVIS will reimburse  Bridge
               for such  payroll  taxes as invoiced  under this  Agreement.  All
               other taxes, charges or levies related to the Services, including
               any income,  franchise,  privilege, or occupation taxes of Bridge
               shall  be  paid  by  Bridge.  Except  as  otherwise  specifically

         4.3.  Bona fide disputes  concerning  invoices shall be referred to the
               parties' respective Contract Managers for resolution.  Any amount
               to which  SAVVIS is entitled as a result of the  resolution  of a
               billing  dispute shall be credited  promptly to SAVVIS'  account.
               Any  amount  to which  Bridge  is  entitled  as a  result  of the
               resolution of a billing dispute shall be paid promptly to Bridge.

                 shall include a proviso  whereby 15 days prior  written  notice
                 shall be provided to SAVVIS prior to coverage  cancellation  or
                 other  material  alteration by either Bridge or the  applicable
                 insurer.  Such  cancellation or material  alteration  shall not
                 relieve  Bridge  of  its  continuing   obligation  to  maintain
                 insurance coverage in accordance with this Section.

         8.2.3.  In lieu of all or part of the insurance  coverage  specified in
                 this  Section,  Bridge  may  self-insure  with  respect  to any
                 insurance coverage, except where expressly prohibited by law.

8.3.     REPRESENTATIONS AND WARRANTIES.

         8.3.1.  Bridge  hereby  warrants  that the Services will be provided in
                 accordance with good business management  practices and that it
                 will use the same care in  rendering  the Services to SAVVIS as
                 Bridge uses in rendering such services to itself.

         8.3.2.  THE FOREGOING  WARRANTIES ARE IN LIEU OF ALL OTHER  WARRANTIES,
                 EXPRESS  OR  IMPLIED,  INCLUDING  WITH  RESPECT  TO  ANY  GOODS
                 PROVIDED  INCIDENT TO THE SERVICES,  THE IMPLIED  WARRANTIES OF
                 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

9.       LIMITATIONS OF LIABILITY
         9.1.    Neither  party  shall be  liable  to the  other  for  indirect,
                 incidental,  consequential,   exemplary,  reliance  or  special
                 damages, including damages for lost profits,  regardless of the
                 form of action whether in contract, indemnity, warranty, strict
                 liability  or  tort,  including  negligence  of any  kind  with
                 respect to the Services or other conduct under this Agreement.

         9.2.    Nothing  contained in this Section  shall limit either  party's
                 liability   to  the  other  for  (a)  willful  or   intentional
                 misconduct,  or (b) injury or death, or damage to tangible real
                 or  tangible  personal   property  or  the  environment,   when
                 proximately caused by SAVVIS' or Bridge's negligence or that of
                 their respective agents, subcontractors or employees.

10.      PROPRIETARY RIGHTS; LICENSE
         10.1.   Bridge   hereby   grants   to   SAVVIS  a   non-exclusive   and
                 non-transferable  license to use all  programming  and software
                 necessary  for  SAVVIS to use the  Services.  Such  license  is
                 granted for the term of this  Agreement for the sole purpose of
                 enabling SAVVIS to use the Services.

                                       31

         10.2.   All title and property rights (including  intellectual property
                 rights)  to  Services  (including  associated  programming  and
                 software)  are and shall remain with  Bridge.  SAVVIS shall not
                 attempt to examine,  copy, alter, reverse engineer,  decompile,
                 disassemble,  tamper with or  otherwise  misuse such  Services,
                 programming and software.

11.      CONFIDENTIALITY
         11.1.   During  the term of this  Agreement  and for a  period  of five
                 years from the date of its expiration or termination (including
                 all  extensions  thereof),  each party  agrees to  maintain  in
                 strict confidence all Confidential  Information.  Neither party
                 shall,  without prior written  consent of the other party,  use
                 the other  party's  Confidential  Information  for any  purpose
                 other than for the  performance of its duties and  obligations,
                 and the  exercise of its  rights,  under this  Agreement.  Each
                 party shall use, and shall cause all  authorized  recipients of
                 the other  party's  Confidential  Information  to use, the same
                 degree  of care  to  protect  the  other  party's  Confidential
                 Information  as  it  uses  to  protect  its  own   Confidential
                 Information, but in any event not less than a reasonable degree
                 of care.

         11.2.   Notwithstanding  Section  11.1,  either  party may disclose the
                 Confidential  Information  of  the  other  party  to:  (a)  its
                 employees  and the  employees,  directors  and  officers of its
                 Affiliates  as  necessary  to  implement  this  Agreement;  (b)
                 employees, agents or representatives of the other party; or (c)
                 other  persons  (including  counsel,  consultants,  lessors  or
                 managers of facilities or equipment used by such party) in need
                 of access to such information for purposes specifically related
                 to  either  party's   responsibilities  under  this  Agreement,
                 provided that any disclosure of Confidential  Information under
                 clause (c) shall be made only upon prior  written  approval  of
                 the other party and subject to the appropriate  assurances that
                 the  recipient  of such  information  shall  hold it in  strict
                 confidence.

         11.3.   Upon the  request  of the party  having  proprietary  rights to
                 Confidential  Information,  the  party  in  possession  of such
                 information  shall  promptly  return it (including  any copies,
                 extracts and  summaries  thereof,  in whatever  form and medium
                 recorded) to the  requesting  party or, with the other  party's
                 written  consent,  shall  promptly  destroy it and  provide the
                 other party with written certification of such destruction.

         11.4.   Either  party may request in writing that the other party waive
                 all or any portion of the requesting  party's  responsibilities
                 relative to the other party's  Confidential  Information.  Such
                 waiver request shall identify the affected  information and the
                 nature of the  proposed  waiver.  The  recipient of the request
                 shall respond  within a reasonable  time and, if it determines,
                 in its sole discretion,  to grant the requested waiver, it will
                 do so in writing over the  signature of an employee  authorized
                 to grant such request.

         11.5.   Bridge  and  SAVVIS   acknowledge   that  any   disclosure   or
                 misappropriation  of  Confidential  Information in violation of
                 this  Agreement  could cause  irreparable

                                       32

                 harm,  the amount of which may be difficult to determine,  thus
                 potentially making any remedy at law or in damages  inadequate.
                 Each party,  therefore,  agrees that the other party shall have
                 the right to apply to any court of competent  jurisdiction  for
                 an order  restraining  any breach or threatened  breach of this
                 Section and for any other appropriate  relief. This right shall
                 be in addition to any other remedy available in law or equity.

         11.6.   A party  requested or ordered by a court or other  governmental
                 authority of competent jurisdiction to disclose another party's
                 Confidential  Information  shall  notify  the  other  party  in
                 advance of any such  disclosure  and,  absent the other party's
                 consent to such disclosure,  use its reasonable best efforts to
                 resist,  and to  assist  the  other  party in  resisting,  such
                 disclosure.  A party  providing  another  party's  Confidential
                 Information to a court or other  governmental  authority  shall
                 use its reasonable best efforts to obtain a protective order or
                 comparable  assurance  that  the  Confidential  Information  so
                 provided will be held in confidence  and not further  disclosed
                 to any other person, absent the owner's prior consent.

         11.7.   The  provisions  of  Section  11.1  above  shall  not  apply to
                 reasonably  necessary  disclosures  in  or in  connection  with
                 filings  under  any  securities  laws,  regulatory  filings  or
                 proceedings,  financial  disclosures  which in the  good  faith
                 judgment  of  the   disclosing   party  are  required  by  law,
                 disclosures   required  by  court  or  tribunal  or   competent
                 jurisdiction,  or disclosures that may be reasonably  necessary
                 in  connection  with the  performance  or  enforcement  of this
                 Agreement or any of the obligations hereof; provided,  however,
                 that if the  receiving  party  would  otherwise  be required to
                 refer to or describe any aspect of this Agreement in any of the
                 preceding  circumstances,  the  receiving  party  shall use its
                 reasonable  efforts to take such steps as are  available  under
                 such circumstances (such as by providing a summary or synopsis)
                 to avoid  disclosure of the financial  terms and  conditions of
                 this   Agreement.   Notwithstanding   any  provisions  of  this
                 Agreement to the contrary,  either party may disclose the terms
                 and  conditions  of  this  Agreement  in  the  course  of a due
                 diligence  review performed in connection with prospective debt
                 financing or equity investment by, or a sale to, a third party,
                 so long as the persons  conducting  such due  diligence  review
                 have agreed to maintain the  confidentiality of such disclosure
                 and not to use such  disclosure  for any purpose other such due
                 diligence review.

12.      INDEMNIFICATIONS
         12.1.   SAVVIS shall indemnify,  defend, and hold Bridge (including any
                 of its  directors,  officers,  employees,  agents  or  assigns)
                 harmless  from any claims,  actions or suits to the extent that
                 such claim or action arises from  Bridge's  provision to SAVVIS
                 of the  Services  and to the extent that such claim,  action or
                 suit does not arise from the gross  negligence  or  intentional
                 misconduct of Bridge. SAVVIS may settle, or otherwise manage at
                 its own cost and  expense  any such  claims,  actions or suits.
                 Bridge  shall  notify  SAVVIS  promptly  in writing of any such
                 claim,  action or suit and  shall  cooperate  with  SAVVIS in a
                 reasonable way to facilitate the settlement or defense thereof.

<PAGE>

         12.2.   Bridge shall indemnify,  defend, and hold SAVVIS (including any
                 of its  directors,  officers,  employees,  agents  or  assigns)
                 harmless  from any claims,  actions or suits to the extent that
                 such claim or action arises from Bridge's  gross  negligence or
                 intentional  misconduct  in  the  provision  to  SAVVIS  of the
                 Services,  unless such  claim,  action or suit also arises from
                 the gross  negligence  or  intentional  misconduct  of  SAVVIS.
                 Bridge  may  settle,  or  otherwise  manage at its own cost and
                 expense any such claims,  actions or suits. SAVVIS shall notify
                 Bridge  promptly in writing of any such  claim,  action or suit
                 and  shall  cooperate  with  Bridge  in  a  reasonable  way  to
                 facilitate the settlement or defense thereof.

13.      DISPUTES
         13.1.   Resolution  of  any  and  all  disputes   arising  from  or  in
                 connection  with this  Agreement,  whether  based on  contract,
                 tort,   statute   or   otherwise,   including   disputes   over
                 arbitrability  and disputes in connection  with claims by third
                 persons  ("DISPUTES")  shall  be  exclusively  governed  by and
                 settled in accordance  with the  provisions of this Section 13.
                 The   foregoing   shall  not  preclude   recourse  to  judicial
                 proceedings to obtain injunctive,  emergency or other equitable
                 relief to enforce the provisions of this  Agreement,  including
                 specific performance, and to decide such issues as are required
                 to be resolved  in  determining  whether to grant such  relief.
                 Resolution  of Disputes with respect to claims by third persons
                 shall be deferred until any judicial  proceedings  with respect
                 thereto are concluded.

         13.2.   The  parties  hereby  agree to submit all  Disputes to rules of
                 arbitration  of the American  Arbitration  Association  and the
                 Missouri  Uniform  Arbitration  Act  (the  "RULES")  under  the
                 following provisions, which shall be final and binding upon the
                 parties,  their successors and assigns,  and that the following
                 provisions   constitute  a  binding  arbitration  clause  under
                 applicable law. Either party may serve process or notice on the
                 other in any  arbitration or litigation in accordance  with the
                 notice provisions hereof. The parties agree not to disclose any
                 information  regarding  any  Dispute  or  the  conduct  of  any
                 arbitration hereunder,  including the existence of such Dispute
                 or such  arbitration,  to any person or entity  other than such
                 employees  or  representatives  of such party as have a need to
                 know.

         13.3.   Either party may commence proceedings  hereunder by delivery of
                 written  notice  providing  a  reasonable  description  of  the
                 Dispute to the other,  including a reference to this  provision
                 (the "DISPUTE NOTICE").  Either party may initiate  arbitration
                 of a Dispute by delivery of a demand therefor (the "ARBITRATION
                 DEMAND") to the other  party not sooner  than 60 calendar  days
                 after the date of  delivery  of the  Dispute  Notice but at any
                 time  thereafter.  The  arbitration  shall be  conducted in St.
                 Louis, Missouri.

         13.4.   The arbitration  shall be conducted by three  arbitrators  (the
                 "ARBITRATORS"), one of whom shall be selected by Bridge, one by
                 SAVVIS,  and the third by  agreement of the other two not later
                 than 10 days after  appointment  of the first two, or,  failing
                 such  agreement,   appointed  pursuant  to  the  Rules.  If  an
                 Arbitrator  becomes  unable  to  serve,  a  successor  shall be
                 selected  or   appointed  in  the  same  manner  in  which  the
                 predecessor Arbitrator was appointed.

                                       34

<PAGE>


         13.5.   The arbitration shall be conducted  pursuant to such procedures
                 as the parties may agree or, in the absence of or failing  such
                 agreement,   pursuant   to  the  Rules.   Notwithstanding   the
                 foregoing, each party shall have the right to inspect the books
                 and records of the other party that are  reasonably  related to
                 the  Dispute,  and  each  party  shall  provide  to the  other,
                 reasonably  in advance of any hearing,  copies of all documents
                 which such party  intends  to present in such  hearing  and the
                 names and addresses of all witnesses whose testimony such party
                 intends to present in such hearing.

         13.6.   All hearings shall be conducted on an expedited  schedule,  and
                 all proceedings shall be confidential.  Either party may at its
                 expense make a stenographic record thereof.

         13.7.   The  Arbitrators  shall complete all hearings not later than 90
                 calendar days after the Arbitrators'  selection or appointment,
                 and shall make a final  award not later than 30  calendar  days
                 thereafter.  The  Arbitrators  shall  apportion  all  costs and
                 expenses of the Arbitration,  including the  Arbitrators'  fees
                 and  expenses  of experts  ("ARBITRATION  COSTS")  between  the
                 prevailing and  non-prevailing  parties as the Arbitrators deem
                 fair and reasonable.  In circumstances where a Dispute has been
                 asserted or defended  against on grounds  that the  Arbitrators
                 deem  manifestly  unreasonable,  the Arbitrators may assess all
                 Arbitration  Costs  against  the  non-prevailing  party and may
                 include in the award the prevailing party's attorneys' fees and
                 expenses in connection with any and all proceedings  under this
                 Section 13.

         13.8.   Either party may assert appropriate statutes of limitation as a
                 defense  in  arbitration;  provided,  that upon  delivery  of a
                 Dispute  Notice  any  such  statute  shall  be  tolled  pending
                 resolution hereunder.

         13.9.   Pending the  resolution of any dispute or  controversy  arising
                 under this  Agreement,  the parties  shall  continue to perform
                 their respective  obligations  hereunder,  and Bridge shall not
                 discontinue,  disconnect  or in  any  other  fashion  cease  to
                 provide  all or any  substantial  portion  of the  Services  to
                 SAVVIS unless otherwise directed by SAVVIS.  This Section shall
                 not apply where SAVVIS is in default under this Agreement.

14.      FORCE MAJEURE
         14.1.   In no event shall  either  party be liable to the other for any
                 failure  to  perform  hereunder  that  is  due to  war,  riots,
                 embargoes,  strikes or other concerted acts of workers (whether
                 of a party hereto or of others), casualties, accidents or other
                 causes to the extent  that such  failure  and the  consequences
                 thereof are reasonably beyond the control and without the fault
                 or negligence of the party claiming  excuse.  Each party shall,
                 with the cooperation of the other party, use reasonable efforts
                 to  mitigate  the  extent of any  failure  to  perform  and the
                 adverse consequences thereof.

         14.2.   If Bridge cannot promptly  provide a suitable  temporary Bridge
                 alternative  to  a  Service   subject  to  an  interruption  in
                 connection  with the  existence or a force  majeure  condition,
                 SAVVIS  may, at its option and at its own cost,  contract  with

                                       35

<PAGE>

                 one or more third parties for any or all affected  Services for
                 the shortest commercially  available period likely to cover the
                 reasonably  expected  duration  of the  Interruption,  and  may
                 suspend  Bridge's  provision of such  Services for such period.
                 Bridge shall not charge SAVVIS for any Services thus  suspended
                 during the period of suspension.  Bridge shall resume provision
                 of the suspended  Services upon the later of the termination or
                 expiration  of  SAVVIS'  legally  binding   commitments   under
                 contracts  with third parties for  alternative  services or the
                 cessation or remedy of the force majeure condition.

         14.3.   In the event that a force majeure  condition shall continue for
                 more than 60 days, SAVVIS may cancel the affected Services with
                 no further liability to Bridge other than for Services received
                 by  SAVVIS  prior  to  the  occurrence  of  the  force  majeure
                 condition.

                 FORM OF LOCAL ADMINISTRATIVE SERVICES AGREEMENT


         This LOCAL  ADMINISTRATIVE  SERVICES  AGREEMENT  (the  "AGREEMENT")  is
effective as of  ______________,  2000 (the  "EFFECTIVE  DATE"),  between [local
SAVVIS entity], a company organized under the laws of [country] ("SAVVIS"),  and
[local Bridge/Telerate  entity], a company organized under the laws of [country]
("PROVIDER").

                                    RECITALS

         A. Provider is engaged in the business of collecting  and  distributing
various financial, news and other data in [country] (the "JURISDICTION").


         B. SAVVIS is engaged in the business of providing Internet backbone and
other data transport services in the Jurisdiction.

         C. SAVVIS Parent and Bridge Parent have entered into an  Administrative
Services    Agreement,    of   even   date   herewith    (the    "ADMINISTRATIVE
SERVICES AGREEMENT") for the  provision  and  receipt of similar  services  on a
world-wide  basis at the parent level as are being  provided and received by the
parties to this Agreement within the Jurisdiction.

         D.  Together with this  Agreement,  the SAVVIS is entering into certain
other  agreements  with  Provider,  or Affiliates of Provider,  related to their
operations in the Jurisdiction,  including Local Transfer Agreements,  Equipment
Collocation Permits, and Local Network Services Agreements.

         NOW,  THEREFORE,  in  consideration  of the  premises,  and the  mutual
covenants  contained  herein and of other good and valuable  consideration,  the
receipt and  adequacy  of which are hereby  acknowledged,  the parties  agree as
follows:

1.       CONTRACT DOCUMENTS AND DEFINITIONS

         1.1.   This  Agreement  shall  consist  of  this  Local  Administrative
                Services Agreement by and between SAVVIS and Provider, including
                all  addenda to this  Agreement  entered  into in the manner set
                forth  herein  (each  an   "ADDENDUM"   and   collectively   the
                "ADDENDA").   This  Agreement  shall  be  interpreted   wherever
                possible to avoid conflicts  between the Sections hereof and the
                Attachments,  provided that if such a conflict shall arise,  the
                Attachments shall control.

         1.2.   Whenever  it is provided  in this  Agreement  for a matter to be
                mutually agreed upon by the parties and set forth in an Addendum
                to this  Agreement,  either  party may  initiate  the process of
                determining  such  matter by  submitting  a proposed  outline or
                contents of such  Addendum to the other party.  Each party shall
                appoint  a  primary  contact  and a  secondary  contact  for the
                completion of such Addendum, who shall be the contact points for

                faith with such  diligence as shall be  commercially  reasonable
                under the  circumstances  to complete such  Addendum,  provided,
                however,  that  neither  party shall be  obligated to enter into
                such an Addendum. Upon the completion of such Addendum, it shall

                as otherwise specifically addressed in this Agreement or Addenda

                     from Provider;

8.2.     INSURANCE.

         8.2.1. At all times during the term of this  Agreement,  Provider shall
                maintain  for  itself,  its  officers,   employees,  agents  and
                representatives  insurance  as shall be mutually  agreed upon by
                the parties and set forth in an  Addendum to this  Agreement  in

         8.2.2. Provider  shall  furnish  to  SAVVIS,   upon  written   request,
                certificates  of  insurance or other  appropriate  documentation
                (including  evidence  of renewal of  insurance)  evidencing  the
                insurance  coverage   referenced  above,  naming  SAVVIS  as  an

                incidental,   consequential,   exemplary,  reliance  or  special
                damages,  including damages for lost profits,  regardless of the
                form of action whether in contract, indemnity,  warranty, strict
                liability or tort, including negligence of any kind with respect
                to the Services or other conduct under this Agreement.

         9.2.   Nothing  contained  in this Section  shall limit either  party's
                liability   to  the  other  for  (a)   willful  or   intentional
                misconduct,  or (b) injury or death,  or damage to tangible real

                proximately  caused by SAVVIS' or Provider's  negligence or that
                of their respective agents, subcontractors or employees.

10.      PROPRIETARY RIGHTS; LICENSE
         10.1.  Provider   hereby   grants   to  SAVVIS  a   non-exclusive   and
                non-transferable  license to use all  programming  and  software
                necessary  for  SAVVIS  to use the  Services.  Such  license  is
                granted for the term of this  Agreement  for the sole purpose of
                enabling SAVVIS to use the Services.

         10.2.  All title and property rights (including  intellectual  property
                rights)  to  Services  (including  associated   programming  and
                software) are and shall remain with  Provider.  SAVVIS shall not

11.      CONFIDENTIALITY
         11.1.  During the term of this Agreement and for a period of five years
                from the date of its  expiration or  termination  (including all
                extensions  thereof),  each party  agrees to  maintain in strict
                confidence all  Confidential  Information.  Neither party shall,
                without prior written consent of the other party,  use the other
                party's Confidential  Information for any purpose other than for
                the performance of its duties and obligations,  and the exercise
                of its rights,  under this Agreement.  Each party shall use, and
                shall  cause all  authorized  recipients  of the  other  party's
                Confidential  Information  to use,  the same  degree  of care to
                protect the other party's Confidential Information as it uses to
                protect its own Confidential  Information,  but in any event not
                less than a reasonable degree of care.

         11.2.  Notwithstanding  Section  11.1,  either  party may  disclose the
                Confidential   Information  of  the  other  party  to:  (a)  its
                employees  and the  employees,  directors  and  officers  of its
                Affiliates  as  necessary  to  implement  this  Agreement;   (b)
                employees,  agents or representatives of the other party; or (c)
                other  persons
                                       45

<PAGE>


                (including   counsel,   consultants,   lessors  or  managers  of
                facilities or equipment used by such party) in need of access to
                such  information  for purposes  specifically  related to either
                party's responsibilities under this Agreement, provided that any
                disclosure of Confidential Information under clause (c) shall be
                made only upon prior  written  approval  of the other  party and
                subject to the appropriate assurances that the recipient of such
                information shall hold it in strict confidence.

         11.3.  Upon the  request  of the  party  having  proprietary  rights to
                Confidential  Information,  the  party  in  possession  of  such
                information  shall  promptly  return it  (including  any copies,
                extracts  and  summaries  thereof,  in whatever  form and medium
                recorded)  to the  requesting  party or, with the other  party's
                written consent, shall promptly destroy it and provide the other
                party with written certification of such destruction.

         11.4.  Either  party may request in writing  that the other party waive
                all or any portion of the  requesting  party's  responsibilities
                relative to the other  party's  Confidential  Information.  Such
                waiver request shall identify the affected  information  and the
                nature of the  proposed  waiver.  The  recipient  of the request
                shall respond within a reasonable time and, if it determines, in
                its sole discretion,  to grant the requested  waiver, it will do
                so in writing over the  signature of an employee  authorized  to
                grant such request.

         11.5.  Provider  and  SAVVIS   acknowledge   that  any   disclosure  or
                misappropriation  of  Confidential  Information  in violation of
                this Agreement could cause irreparable harm, the amount of which
                may be  difficult  to  determine,  thus  potentially  making any
                remedy at law or in damages inadequate.  Each party,  therefore,
                agrees that the other party shall have the right to apply to any
                court of competent  jurisdiction  for an order  restraining  any
                breach or  threatened  breach of this  Section and for any other
                appropriate relief. This right shall be in addition to any other
                remedy available in law or equity.

         11.6.  A party  requested  or ordered by a court or other  governmental
                authority of competent  jurisdiction to disclose another party's
                Confidential Information shall notify the other party in advance
                of any such  disclosure and, absent the other party's consent to
                such disclosure,  use its reasonable best efforts to resist, and
                to assist the other party in resisting, such disclosure. A party
                providing another party's Confidential Information to a court or
                other  governmental  authority  shall  use its  reasonable  best
                efforts to obtain a  protective  order or  comparable  assurance
                that the  Confidential  Information  so provided will be held in
                confidence and not further disclosed to any other person, absent
                the owner's prior consent.

         11.7.  The  provisions  of  Section  11.1  above  shall  not  apply  to
                reasonably  necessary  disclosures  in  or  in  connection  with
                filings  under  any  securities  laws,   regulatory  filings  or
                proceedings,  financial  disclosures  which  in the  good  faith
                judgment  of  the   disclosing   party  are   required  by  law,
                disclosures   required  by  court  or   tribunal  or

                                       46

<PAGE>

                competent  jurisdiction,  or disclosures  that may be reasonably
                necessary in connection  with the  performance or enforcement of
                this  Agreement  or  any of the  obligations  hereof;  provided,
                however, that if the receiving party would otherwise be required
                to refer to or describe  any aspect of this  Agreement in any of
                the preceding  circumstances,  the receiving party shall use its
                reasonable  efforts  to take such steps as are  available  under
                such circumstances  (such as by providing a summary or synopsis)
                to avoid  disclosure  of the financial  terms and  conditions of
                this Agreement. Notwithstanding any provisions of this Agreement
                to the  contrary,  either  party  may  disclose  the  terms  and
                conditions  of this  Agreement in the course of a due  diligence
                review  performed in connection with  prospective debt financing
                or equity investment by, or a sale to, a third party, so long as
                the persons  conducting such due diligence review have agreed to
                maintain the  confidentiality  of such disclosure and not to use
                such disclosure for any purpose other such due diligence review.

12.      INDEMNIFICATIONS
         12.1.  SAVVIS shall indemnify, defend, and hold Provider (including any
                of  its  directors,  officers,  employees,  agents  or  assigns)
                harmless  from any  claims,  actions or suits to the extent that
                such claim or action arises from Provider's  provision to SAVVIS
                of the  Services  and to the extent that such  claim,  action or
                suit does not arise  from the gross  negligence  or  intentional
                misconduct of Provider.  SAVVIS may settle,  or otherwise manage
                at its own cost and expense any such  claims,  actions or suits.

                claim,  action  or suit and  shall  cooperate  with  SAVVIS in a
                reasonable way to facilitate the settlement or defense thereof.

         12.2.  Provider shall indemnify, defend, and hold SAVVIS (including any
                of  its  directors,  officers,  employees,  agents  or  assigns)
                harmless  from any  claims,  actions or suits to the extent that
                such claim or action arises from Provider's  gross negligence or
                intentional  misconduct  in  the  provision  to  SAVVIS  of  the
                Services, unless such claim, action or suit also arises from the
                gross negligence or intentional  misconduct of SAVVIS.  Provider
                may settle,  or otherwise manage at its own cost and expense any
                such claims,  actions or suits.  SAVVIS  shall  notify  Provider
                promptly in writing of any such claim,  action or suit and shall
                cooperate  with Provider in a reasonable  way to facilitate  the
                settlement or defense thereof.

13.      DISPUTES
         13.1.  Resolution of any and all disputes arising from or in connection
                with this Agreement, whether based on contract, tort, statute or

                connection  with claims by third persons  ("DISPUTES")  shall be
                exclusively  governed  by and  settled  in  accordance  with the

                issues as are required to be resolved in determining  whether to
                grant such relief. Resolution of Disputes with respect to claims
                by  third   persons   shall  be  deferred   until  any  judicial
                proceedings with respect thereto are concluded.

                arbitration  of the  American  Arbitration  Association  and the
                Missouri  Uniform   Arbitration  Act  (the  "RULES")  under  the
                following provisions,  which shall be final and binding upon the
                parties,  their  successors and assigns,  and that the following
                provisions   constitute  a  binding   arbitration  clause  under
                applicable  law. Either party may serve process or notice on the
                other in any  arbitration  or litigation in accordance  with the
                notice provisions  hereof. The parties agree not to disclose any
                information   regarding  any  Dispute  or  the  conduct  of  any
                arbitration  hereunder,  including the existence of such Dispute
                or such  arbitration,  to any  person or entity  other than such
                employees  or  representatives  of such  party as have a need to
                know.

         13.3.  Either party may commence  proceedings  hereunder by delivery of
                written notice providing a reasonable description of the Dispute
                to the other,  including  a  reference  to this  provision  (the
                "DISPUTE  NOTICE").  Either party may initiate  arbitration of a
                Dispute  by  delivery  of a demand  therefor  (the  "ARBITRATION
                DEMAND") to the other  party not sooner  than 60  calendar  days
                after the date of delivery of the Dispute Notice but at any time
                thereafter.  The  arbitration  shall be conducted in St.  Louis,
                Missouri.

         13.4.  The  arbitration  shall be conducted by three  arbitrators  (the
                "ARBITRATORS"),  one of whom shall be selected by Provider,  one
                by SAVVIS, and the third by agreement of the other two not later
                than 10 days after  appointment  of the first two,  or,  failing
                such  agreement,   appointed   pursuant  to  the  Rules.  If  an
                Arbitrator  becomes  unable  to  serve,  a  successor  shall  be
                selected  or   appointed   in  the  same  manner  in  which  the
                predecessor Arbitrator was appointed.

         13.5.  The arbitration  shall be conducted  pursuant to such procedures
                as the parties  may agree or, in the absence of or failing  such
                agreement, pursuant to the Rules. Notwithstanding the foregoing,
                each party shall have the right to inspect the books and records
                of the other party that are  reasonably  related to the Dispute,
                and each party shall provide to the other, reasonably in advance
                of any hearing, copies of all documents which such party intends
                to present in such  hearing and the names and  addresses  of all
                witnesses  whose testimony such party intends to present in such
                hearing.

         13.6.  All hearings  shall be conducted on an expedited  schedule,  and
                all proceedings  shall be confidential.  Either party may at its
                expense make a stenographic record thereof.

         13.7.  The  Arbitrators  shall  complete all hearings not later than 90
                calendar days after the  Arbitrators'  selection or appointment,
                and shall  make a final  award not later than 30  calendar  days
                thereafter.  The  Arbitrators  shall  apportion  all  costs  and
                expenses of the Arbitration, including the Arbitrators' fees and
                expenses of experts ("ARBITRATION COSTS") between the prevailing
                and  non-prevailing  parties  as the  Arbitrators  deem fair and
                reasonable.  In circumstances  where a Dispute has been asserted
                or  defended  against  on  grounds  that  the  Arbitrators  deem
                manifestly   unreasonable,   the   Arbitrators  may  assess  all
                Arbitration  Costs  against  the  non-

                                       48

<PAGE>

                prevailing  party and may  include  in the award the  prevailing
                party's  attorneys' fees and expenses in connection with any and
                all proceedings under this Section 13.

         13.8.  Either party may assert appropriate  statutes of limitation as a
                defense  in  arbitration;  provided,  that  upon  delivery  of a
                Dispute   Notice  any  such  statute  shall  be  tolled  pending
                resolution hereunder.

         13.9.  Pending the  resolution  of any dispute or  controversy  arising
                under this  Agreement,  the  parties  shall  continue to perform
                their respective obligations  hereunder,  and Provider shall not
                discontinue, disconnect or in any other fashion cease to provide
                all or any substantial  portion of the Services to SAVVIS unless
                otherwise directed by SAVVIS. This Section shall not apply where
                SAVVIS is in default under this Agreement.

14.      FORCE MAJEURE
         14.1.  In no event  shall  either  party be liable to the other for any
                failure  to  perform  hereunder  that  is  due  to  war,  riots,
                embargoes,  strikes or other concerted acts of workers  (whether
                of a party hereto or of others), casualties,  accidents or other
                causes to the  extent  that such  failure  and the  consequences
                thereof are reasonably  beyond the control and without the fault
                or negligence of the party  claiming  excuse.  Each party shall,
                with the cooperation of the other party, use reasonable  efforts
                to mitigate the extent of any failure to perform and the adverse
                consequences thereof.

         14.2.  If  Provider  cannot  promptly  provide  a  suitable   temporary
                Provider  alternative to a Service subject to an interruption in
                connection  with the  existence  or a force  majeure  condition,
                SAVVIS may, at its option and at its own cost, contract with one
                or more third  parties for any or all affected  Services for the
                shortest  commercially  available  period  likely  to cover  the
                reasonably  expected  duration  of  the  Interruption,  and  may
                suspend  Provider's  provision of such Services for such period.
                Provider shall not charge SAVVIS for any Services thus suspended
                during the period of suspension. Provider shall resume provision
                of the suspended  Services upon the later of the  termination or
                expiration  of  SAVVIS'   legally  binding   commitments   under
                contracts  with third  parties for  alternative  services or the
                cessation or remedy of the force majeure condition.

         14.3.  In the event that a force majeure  condition  shall continue for
                more than 60 days,  SAVVIS may cancel the affected Services with
                no  further  liability  to  Provider  other  than  for  Services
                received by SAVVIS prior to the  occurrence of the force majeure
                condition.

15.      GENERAL PROVISIONS
         15.1.  NO THIRD-PARTY  BENEFICIARIES.  [This Agreement shall not confer
                any rights or remedies  upon any person or entity other than the
                parties and their respective  successors and permitted assigns.]
                [Except as expressly provided in this Agreement, nothing in this
                Agreement  will create or confer any rights or other

                                       49

                Agreement  whether  pursuant to the  Contracts  (Rights of Third
                Parties) Act, 1999 or otherwise.]

         15.2.  ENTIRE  AGREEMENT.   This  Agreement  (including  the  documents
                referred to herein) constitutes the entire agreement between the
                parties and supersedes any prior understandings,  agreements, or
                representations  by or between the parties,  written or oral, to
                the extent they related in any way to the subject matter hereof.

         15.3.  SUCCESSION AND ASSIGNMENT.  This Agreement shall be binding upon
                and inure to the benefit of the parties  named  herein and their
                respective successors and permitted assigns. No party may assign
                either  this  Agreement  or  any of its  rights,  interests,  or
                obligations  hereunder without the prior written approval of the
                other party, which consent shall not be unreasonably withheld.

         15.4.  COUNTERPARTS.  This  Agreement  may be  executed  in one or more
                counterparts,  each of which shall be deemed an original but all
                of which together will constitute one and the same instrument.

         15.5.  HEADINGS.  The Section headings  contained in this Agreement are
                inserted  for  convenience  only and shall not affect in any way

                or any other  jurisdiction)  that would cause the application of

               FORM OF LOCAL CONTRACT OF ASSIGNMENT AND ASSUMPTION

                      CONTRACT OF ASSIGNMENT AND ASSUMPTION

                  This  Contract  is  entered  into  as  of  this  ____  day  of
_________,  2000 by and  between  SAVVIS  [______________],  a [private  limited
liability]  company  organized  under the laws of  [______________]  ("SAVVIS"),
[having  a  non-registered   __________   branch],   and   [______________],   a
[______________]   company   organized   under  the  laws  of   [______________]
("Assignor").

                  WHEREAS,  SAVVIS is acquiring  certain assets and  liabilities
from various  companies  affiliated  with Assignor,  such assets and liabilities
comprising  and  relating to the IP Network  that  Assignor  and its  affiliated
companies currently own and operate; and

                  WHEREAS,  Assignor  desires  to assign to  SAVVIS  and  SAVVIS
desires to assume  from  Assignor  certain  contracts  and  liabilities  as more
particularly  set forth at  Schedule  1 to this  Contract  (the  "Contracts  and
Liabilities").

                  NOW, THEREFORE, for good and valuable consideration, including
the provisions  and covenants  herein,  the receipt and  sufficiency of which is
hereby acknowledged, SAVVIS and Assignor agree as follows:

         1.       Assignor hereby  assigns, transfers and delivers to SAVVIS the
Contracts and Liabilities and all of its right,  title and interest  therein and
delegates all of Assignor's duties and obligations  attached to the Contract and
Liabilities.

         2.       SAVVIS hereby accepts the foregoing assignment and assumes and
agrees  to  keep,  observe,  perform,  pay and  discharge  when  due the  terms,
covenants,  conditions and obligations of Assignor  related to the Contracts and
Liabilities, and hereby releases Assignor from its obligations thereunder.

         3.       Notwithstanding the foregoing, if  the assignment and transfer
of any of the Contracts  and  Liabilities would cause a breach thereof and if no
required consent to such assignment  and  transfer  has  been  obtained from the
third parties involved,  then   such  Contracts  and  Liabilities  shall  not be
assigned  and transferred, but,  instead,  Assignor  shall  continue to hold its
interests in such Contracts and  Liabilities in trust for the benefit of SAVVIS,
shall receive in trust and remit as  promptly  as  possible  to SAVVIS any money
paid  thereunder  to Assignor and shall cooperate in any reasonable  arrangement
or action requested by SAVVIS to secure for  SAVVIS  all  benefits   under  such
Contracts and Liabilities.

         4.       From and after the date of this Contract,  Assignor and SAVVIS
shall  do  such acts and execute  such  documents  and  instruments  as  may  be
reasonably required to make effective the transactions contemplated  thereby. In
the event acts contemplated by this Agreement have not been fully effected as of
the date of this Contract,  SAVVIS and  Assignor  will  continue  after


                                       55

<PAGE>

the date of this Contract, without further  consideration,  to  use  their  best
efforts to carry out such transactions.

         5.   Assignor and  SAVVIS  hereby  agree  that to the extent any of the
Contracts and Liabilities  are actually  assigned to SAVVIS prior to the date of
this Contract, Assignor shall indemnify SAVVIS for any losses due to obligations
that  arose  under  such  Contracts  and  Liabilities  prior to the date of this
Contract and to the extent any of the Contracts and Liabilities are not assigned
to SAVVIS until after the date of this Contract, SAVVIS shall indemnify Assignor
for  any  losses  due  to  obligations  that  arise  under  such  Contracts  and

                                    EXHIBIT H
                      FORM OF EQUIPMENT COLLOCATION PERMIT

                          EQUIPMENT COLLOCATION PERMIT

                  This EQUIPMENT COLLOCATION PERMIT (the "Agreement") is made as
of the ____ day of _________,  2000,  by and between  [Bridge  Subsidiary]  (the
"Company") and [Savvis Subsidiary] (the "Customer").

                  WHEREAS,  the Company  occupies  the  premises  identified  on
Exhibit A attached hereto and incorporated herein by reference (the "Premises"),
which are leased by the Company under the lease  described on Exhibit B attached
hereto,  including the lease term and renewal  options  specified  therein,  and
incorporated herein by reference (the "Lease"); and

                  WHEREAS,  the Customer and the Company desire to enter into an
arrangement  permitting  the  Customer  to locate  certain of its  equipment  in
certain portions of the Premises, on and subject to the terms and conditions set
forth herein related to the Customer's collocation of the equipment;

                  NOW,  THEREFORE,  for and in consideration of the premises and
the mutual agreements herein, the parties hereby agree as follows:

1.       SPACE.

(a) To the extent  permitted by this  Agreement,  the Customer may place certain
telecommunications  equipment (the  "Equipment")  within the Premises during the
Term  (hereinafter  defined)  of this  Agreement  and may use the  Equipment  in
accordance  with the terms and  conditions  of this  Agreement and in accordance
with  applicable  laws and code. The precise  locations (the "Space") within the
Premises  where the Equipment may be placed and used by the Customer shall be as
designated  by the Company in written  notice(s)  to the  Customer.  The Company
shall maintain exclusive control over the manner and method of the placement and
use of the  Equipment  within  the  Space.  In  connection  with the  permission
established  under this  Agreement,  the Customer  shall have no  possessory  or
occupancy  rights with respect to the Space or control over the Space, but shall
have only permission to place and use the Equipment  within the Space,  together
with unrestricted access to the Equipment  twenty-four hours a day, seven days a
week.

(b) The Customer  shall use its  reasonable  best efforts to abide by applicable
terms and conditions of the Lease and any other agreements or indentures binding
on the Company  with  respect to the  Premises,  upon notice from the Company of
such  terms and  conditions  from  time to time  throughout  the Term;  and this
Agreement  and the  rights  of the  Customer  hereunder  shall  be  subject  and
subordinate  to the terms and  conditions of the Lease and other  agreements and
indentures in all respects.  The Company shall  promptly give written  notice to
the Customer of any notice of default they may receive pursuant to the Lease. If
the  Customer  shall not abide by any such  terms or  conditions,  upon 15 days'
written  notice  to  the  Customer,   the  Company  may

                                       68

<PAGE>

revoke the  permission  established  under this  Agreement  with  respect to the
applicable  Space and Premises and the Company may  terminate  the rights of the
Customer under this Agreement with respect to such Space and Premises.

(c) The Equipment and its method of installation within the Space shall, in each
instance,  be approved in writing by the Company in advance.  The Customer shall
not place any additional  equipment in the Space and shall not move or alter the
location  of the  Equipment  within  the Space  without  having  received  prior
approval in writing from the Company.  Additional  Space within the Premises for
the location of  additional  Equipment  may be obtained  upon the prior  written
consent  of the  Company  which  consent  shall  not be  unreasonably  withheld;
provided,  "unreasonable"  shall  be  determined  from  the  perspective  of the
Company,  including  considerations  regarding the availability of space to meet
the Company's needs and the needs of any present or potential customers to which
the Company rents space at the Premises.

(d) Upon 30 days' prior written notice or, in the event of an emergency,  within
such shorter time as may be reasonably  determined  appropriate  by the Company,
the  Company may require the  Customer  to  relocate  the  Equipment  within the
Premises and may  redesignate the Space for the relocated  Equipment;  provided,
however,  the site of relocation shall be prepared for installation prior to any
required  relocation  and shall afford  substantially  comparable  environmental
conditions for the Equipment and substantially  comparable  accessibility to the
Equipment. All costs of relocating the Equipment shall be borne by the Customer,
excluding, however, the cost, if any, of improving the redesignated Space.

(e) Upon  written  request of the Customer and at the  Customer's  expense,  the
Customer may require that fencing,  caging, cabinets or other similar protective
covering for the Equipment be installed if (i) there is  sufficient  room in the
applicable Space and Premises for such  installations,  (ii) such  installations
will not unreasonably  interfere with the Company's use,  occupancy or planning,
and  will  not  unreasonably  interfere  with  the  Company's  equipment  or the
equipment of other  collocators,  and (iii) with respect to any Premises subject
to the Lease or other agreements or indentures, such installations are permitted
under the terms and conditions of the Lease or other agreements or indentures.

(f)  If the  placement  or use of the  Equipment  in the  Space  results  in any
violation  or claim of  violation  of any of the  Lease or other  agreements  or
indentures,  then in the event the Company shall be unable, at a cost acceptable
to the  Company,  to cure such  violation  or  secure a waiver of such  claim of
violation,  the  Company  may  undertake  to find other  suitable  space for the
Equipment  within the applicable  Space and Premises and relocate such Equipment
to other suitable location for the balance of the Term of this Agreement.

2.       TERM.

(a) The initial term (the "Initial  Term") of the permission  established  under
this Agreement  pertaining to the placement and use of the Equipment  within the
Space shall commence on the date hereof and shall continue thereafter until such
time as the  applicable  Lease expires.  If the term of the applicable  Lease is
extended,  then the Customer shall have the option, upon prior written notice to
the  Company,  to renew this  Agreement  for an  additional  term (the  "Renewal

                                       69

<PAGE>

Term"), which Renewal Term shall be conterminous with the term of the applicable
extended term under the Lease,  on the terms and conditions  otherwise set forth
in  this  Agreement.  The  Initial  Term  and the  Renewal  Term  are  sometimes
collectively  referred  to as the  "Term."  Notwithstanding  anything  herein or
elsewhere  to the  contrary,  however,  the Term  shall be  subject  to  earlier
termination as may be provided herein.

(b) The option to renew this  Agreement  with respect to the  Premises  shall be
contingent on the Company's continued occupation and ownership or leasing of the
Premises and shall be contingent  upon the Customer's  compliance with the terms
and conditions of this Agreement. In the event the Company shall cease to occupy
any of the Premises or shall default under this  Agreement,  the option to renew
this  Agreement  shall  expire with  respect to the  applicable  Premises or the
entirety of the Premises, as the case may be.

(c)  Following the  expiration of the Term,  this  Agreement  shall  continue in
effect on a  month-to-month  basis upon the same terms and conditions  otherwise
set forth  herein,  unless and until  terminated  by either the  Customer or the
Company upon at least 30 days' prior written notice to the other.

(d)  Notwithstanding  anything herein or elsewhere to the contrary,  the Company
reserves the right,  in its  discretion,  to revoke the  permission  established
under this Agreement  with respect to the  applicable  Space within any Premises
and to terminate  the rights of Customer  under this  Agreement  with respect to
such Space and Premises  immediately  upon written notice in the event that, for
whatever reason,  the Company loses its right to occupy the applicable  Premises
or its right to permit the collocation of Equipment within such Premises. In the
event the  Company  elects to exercise  its right to  terminate  the Lease,  the
Company shall give the Customer 6 months  written  notice of its  termination of
the Lease and the intended resulting termination of this Agreement.

3. CONSIDERATION.  The Customer agrees to pay the Company such amounts as may be
set forth on the Collocate  Schedule for the permission  established  under this
Agreement with respect to the scheduled  Space and Premises.  Such amounts shall
be payable  in equal  monthly  installments  in advance on the first day of each
calendar month during the Term.

4. CONDITION OF THE  PREMISES.  The  Customer  approves the Premises in  "as is"
condition as of the date of this Agreement,  and  acknowledges  that the Company
has no obligation to make alterations, improvements or additions, decorations or
changes  within the  Premises or the Space.  The Company  acknowledges  that the
Equipment is personal  property of the Customer and not a fixture,  and that the
Company shall not have any lienable interest in the Equipment.

5. ASSIGNMENT. The Agreement is personal to the parties, and may not be assigned
by either party without the prior written consent of the other.

6. TERMINATION  OR  EXPIRATION.  At the  expiration  of  the  Term  (or  earlier
termination of this Agreement), the Customer shall remove the Equipment from the
Premises  at the  Customer's

                                       70

<PAGE>

expense,  and the Space  shall be  restored by the  Company,  at the  Customer's
expense  (such  expense to be defrayed by  reimbursing  the Company for the same
upon demand) to  substantially  the same as the condition as of the date of this
Agreement.

7.  DEFAULT. If the Customer  breaches any term or condition of this  Agreement,
the Company,  after providing the Customer with notice of such breach, may elect
by written notice to the Customer to terminate this Agreement; provided, however
that the Customer  shall have 30 days from the time it receives such notice from
the Company of a breach to cure any such  default.  In addition to such right of
termination,  the  Company  shall  have any and all other  rights  and  remedies
afforded to the Company at law or in equity.

8. INDEMNIFICATION.

(a) The Customer covenants and agrees to indemnify and hold the Company harmless
from and  against  any and all suits,  actions,  claims,  damages,  charges  and
expenses,  including  reasonable  attorney  fees, for damages or injuries to the
Space or the Premises  occurring or claimed to have  occurred in, upon, or about
the Space or the Premises as a result of the  Customer's  conduct or omission in
placing,  operating or removing the Equipment or using the Equipment  within the
Space, unless arising from the negligence or willful misconduct of the Company.

(b) The Company covenants and agrees to indemnify and hold the Customer harmless
from and  against  any and all suits,  actions,  claims,  damages,  charges  and
expenses,  including  reasonable  attorney  fees, for damages or injuries to the
Equipment  occurring or claimed to have occurred in, upon, or about the Space or
the Premises as a result of the negligence or willful  misconduct of the Company
in handling the  Equipment or using the Space or the  Premises,  unless  arising
from the negligence or willful misconduct of the Customer.

9. LIMITATION OF LIABILITY.

(a) Liability  for Damages to Property.  The Company shall not be liable for any
damages  whatsoever to the Customer's  property resulting from the installation,
maintenance,  repair or removal of Equipment  and  associated  wiring unless the
damage is caused by the Company's negligence or willful misconduct.

(b) Liability  for Equipment not Provided by the Company.  The Company shall not
be liable for any damages whatsoever associated with facilities or Equipment not
furnished by the Company or for any act or omission of the Customer or any other
entity furnishing facilities or Equipment.

(c) Liability for Force Majeure Events.  The Company shall not be liable for any
failure of  performance  due to causes  beyond its  control,  including  but not
limited  to acts of God,  fire,  flood or  other  catastrophes;  any law,  order
regulation,  direction, action or request of the United States Government, or of
any other government,  including state and local governments  having or claiming
jurisdiction or of any department,  agency, commission,  bureau, corporation, or
other  instrumentality  of any federal,  state, or local  government,  or of any
civil or military authority;  national emergencies;  unavailability of materials
or  rights-of-way;  insurrections;  riots;  wars;  or strikes,  lock-outs,  work
stoppages, labor difficulties, or utilities/power outages.

for special,  consequential,  lost profit,  exemplary,  or punitive damages as a
result of its performance or  nonperformance of this Agreement or as a result of
any default under or breach of this Agreement.

(e) No Claims against the Company's  Landlords.  The Customer  acknowledges  the
owners of any Premises subject to the Lease have no  responsibilities or duties,
direct or  indirect,  to the  Customer,  and the Customer  disclaims  any rights
against or  recourse to (i) the owners of any  Premises  subject to the Lease or
(ii) such Premises.  In furtherance of this  acknowledgment and disclaimer,  the
Customer  releases and waives any claim  against  such owners (such  release and
waiver  being for the  benefit  of, and  enforceable  by such owners as intended
third party beneficiaries).

10. CASUALTY OR EMINENT DOMAIN.  In the event of any taking by eminent domain or
damage by fire or other  casualty to the  Premises  and/or  Space,  the Customer
shall acquiesce and be bound by any action taken by or agreement entered into by
the Company with respect  thereto,  and in any event the Customer shall not have
(and hereby waives and releases) any claim with respect to any award, damages or
proceeds associated with any such taking or damage.

merged within this  Agreement,  which alone fully and completely  sets forth the

                  1.  Interest.  This Note shall bear  interest on the aggregate
unpaid  principal  amount  thereof  from the date  hereof at the  fixed  rate of
interest equal to ten percent (10%) per annum.

                  2. Interest and Principal Payments;  Maturity. This Note shall

           violation,  conflict,  breach,  default,  acceleration,  termination,
           modification,  cancellation,  failure to give notice, or a lien would
           not impair the value of use of the Assets or have a material  adverse
           effect on  ability  of the  parties to  consummate  the  transactions
           contemplated  by  this  Agreement,  neither  the  execution  and  the
           delivery of this Agreement nor the  consummation of the  transactions
           contemplated hereby by the Seller will:

           adverse effect on the Assets,  no event has occurred  which,  through
           the  passage  of  time  or the  giving  of  notice,  or  both,  would
           constitute,  and  neither the  execution  of this  Agreement  nor the
           consummation  of the  transactions  contemplated  hereby  do or  will
           constitute  or result in, a breach or violation  of or default  under
           any contract,  or would cause the  acceleration  of any obligation of
           any party  thereto  or the  creation  of any  Impermissible  Security

                               SUBLEASE AGREEMENT


         THIS  SUBLEASE  AGREEMENT  ("Sublease")  is made as of the  ____ day of
January,  2000 (the "Effective Date"), by and between BRIDGE INFORMATION SYSTEMS
AMERICA,  INC., a Delaware corporation  ("Sublessor") and SAVVIS  COMMUNICATIONS
CORPORATION, a Missouri corporation ("Sublessee").

         WHEREAS,  Sublessor  entered into a revised Master Lease  Agreement,  a
copy of which is attached hereto as EXHIBIT A (the "Master Lease"), with General
Electric  Capital  Corporation for itself and as Agent for certain  Participants
(collectively, the "Lessor"); unless otherwise defined herein, capitalized terms
used as defined  terms  shall  have the  meaning  assigned  to such terms in the
Master Lease;

         WHEREAS,  in  conjunction  with the planned  spin-off of  Sublessee  by
Sublessor,  Sublessor  has obtained the consent of Lessor,  which consent is set
forth in the Master Lease attached hereto; and

         WHEREAS,  Sublessor  and  Sublessee  desire to set forth in writing the
terms and conditions of the sublease;

         NOW,  THEREFORE,  in  consideration  of the  recitals  and  the  mutual
covenants,  representations,  warranties,  conditions and  agreements  hereunder
expressed, Sublessor and Sublessee agree as follows:

I.       SUBLEASING ARRANGEMENT:

         Sublessor  agrees to lease to Sublessee,  and Sublessee agrees to lease
from  Sublessor,  the  equipment  (the  "Equipment")  described in the equipment
schedules attached hereto as EXHIBIT B (the "Equipment  Schedules"),  subject to
the terms set forth herein and in the Equipment Schedules.

II.      TERM, RENT AND PAYMENT:

         (a) The term of this  Sublease (the "Term") with respect to any item of
the Equipment shall be the remaining term for such Equipment as set forth in the
Master Lease and the Equipment Schedules; provided, however, that the Term shall
begin effective from and after the Effective Date hereof.

         (b) Rent  shall be paid  directly  to  Sublessor  by wire  transfer  of
immediately  available  funds to:  Bankers  Trust New York,  New York,  New York
10006, Account No. 50-202-962, ABA No. 021-001-033,  or to such other account as
Sublessor may direct in writing;  and shall be effective upon receipt.  Payments
of Rent shall be in the amount set forth in,  and due in  accordance  with,  the
provisions  of  the  applicable   Equipment  Schedules  and  the  other  related
provisions  contained in the  schedules to the Master Lease  (together  with the
Equipment

                                       87

<PAGE>

Schedules,  individually and collectively, the "Schedules"). If Rent is not paid
within ten (10) days of its due date,  Sublessee  agrees to pay to  Sublessor  a
late charge of Five Cents  ($0.05) per dollar on, and in addition to, the amount
of such Rent but not exceeding the lawful maximum, if any.

         (c) Except as provided for in (d) below,  Sublessee  shall pay Rent, as
provided for herein without deduction or set-off.  In the event of a non-payment
of Rent by  Sublessee,  Sublessor  may continue to make  payments to Lessor with
respect to the  Equipment,  with the right to set-off any such payments  against
amounts due by the Sublessor or any of its affiliates to Sublessee or any of its
affiliates under any agreement.

         (d) The  parties  agree that this  Sublease  is  expressly  subject and
subordinate  to the Lessor's  interest in and to the Equipment and to the Master
Lease and the rights of the Lessor  under the  Master  Lease and that,  upon the
declaration by the Lessor of a Default under the Master Lease and written notice
thereof to the parties by the Lessor,  at the sole discretion of the Lessor,  as
specified  in such notice:  (a)  Sublessee  shall make all payments  then due or
thereafter  becoming due under this  Sublease  directly to the Lessor and/or (b)
this  Sublease  shall be  terminated  and the  Lessor  shall have all rights and
remedies specified in the Master Lease.

III.     TAXES:

         Sublessee  shall  have no  liability  for taxes  imposed  by the United
States of America or any State or political  subdivision thereof which are on or
measured by the net income of Lessor or  Sublessor.  Sublessee  shall report (to
the extent that it is legally  permissible)  and pay  promptly  all other taxes,
fees and assessments due, imposed,  assessed or levied against any Equipment (or
the  purchase,  ownership,  delivery,  leasing,  possession,  use  or  operation
thereof),  this Agreement (or any rentals or receipts hereunder),  any Schedule,
Lessor,  Sublessor  or  Sublessee  by  any  foreign,  federal,  state  or  local
government or taxing  authority during or related to the term of this Agreement,
including, without limitation, all license and registration fees, and all sales,
use, personal property, excise, gross receipts, franchise, stamp or other taxes,
imposts,  duties and charges,  together  with any  penalties,  fines or interest
thereon (all hereinafter  called "Taxes").  Sublessee shall (i) reimburse Lessor
and/or  Sublessor,  as  appropriate  (on an  after-tax  basis),  upon receipt of
written request for  reimbursement  for any Taxes charged to or assessed against
Lessor or  Sublessor;  (ii) on request  of Lessor  and/or  Sublessor,  submit to
Lessor and/or Sublessor, as appropriate, written evidence of Sublessee's payment
of Taxes, (iii) on all reports or returns show the ownership of the Equipment by
Lessor, and (iv) send a copy thereof to Lessor and Sublessor.

IV.      REPORTS:

         (a) Sublessee  will notify  Sublessor in writing,  within ten (10) days
after  any  tax or  other  lien  shall  attach  to any  Equipment,  of the  full
particulars  thereof and of the  location of such  Equipment on the date of such
notification.

         (b) Sublessee will permit Lessor and Sublessor to inspect the Equipment
and all  maintenance  records with respect  thereto during normal business hours
upon reasonable notice.

                                       88

<PAGE>

         (c) Subject to the following sentence, Sublessee will ensure that the
Equipment is located at the  Equipment  Location  (specified  in the  applicable
Schedule) within the Continental United States. Sublessee may move the Equipment
from the  Equipment  Location to a new location  within the  Continental  United
States  provided  that,  within  five (5) days  after  the end of each  calendar
quarter: (i) Sublessee shall provide to Sublessor written notice identifying the
Equipment  which has been relocated  during the immediately  preceding  calendar
quarter,  the old Equipment  Location and the new Equipment  Location;  and (ii)
Sublessee   shall  deliver  to  Sublessor  such  documents  and  instruments  as
reasonably  may be  required  by Lessor or  Sublessor  in  connection  with such
relocation,  including  (without  limitation)  Uniform Commercial Code Financing
Statements and (if required by Lessor or Sublessor) Estoppel/Waiver  Agreements,
to be filed at  Sublessee's  expense.  Upon  Lessor's  or  Sublessor's  request,
Sublessee  promptly  will  notify  Lessor  and/or  Sublessor  in  writing of the
location of any Equipment as of the date of such notification.

         (d) Sublessee will promptly and fully report to Sublessor in writing if
any Equipment is lost or damaged (where the estimated  repair costs would exceed
ten percent (10%) of its then fair market value), or is otherwise involved in an
accident causing personal injury or property damage.

         (e) Within thirty (30) days after any request by Lessor and  Sublessor,
Sublessee  will furnish to Sublessor a certificate  of an authorized  officer of
Sublessee  stating that he has reviewed the activities of Sublessee and that, to
the best of his knowledge,  there exists no Default (as hereinafter  defined) or
event  which,  with the giving of notice or the lapse of time (or  both),  would
become a Default.

V.       USE AND MAINTENANCE:

         (a)  Sublessee  agrees  that the  Equipment  will be used by  Sublessee
solely  in the  conduct  of its  business  and in a  manner  complying  with all
applicable  Federal,  state and local laws and  regulations  and any  applicable
insurance policies, and Sublessee shall not discontinue use of the Equipment.

         (b) Sublessee  will keep the Equipment  free and clear of all liens and
encumbrances other than those which result from acts of Lessor or Sublessor.

VI.      SERVICE:

         (a)  Sublessee  will,  at its  sole  expense,  maintain  each  unit  of
Equipment  in  good  operating  order,  repair,   condition  and  appearance  in
accordance with  manufacturer's  recommendations,  normal wear and tear excepted
and  Sublessee's  standard  practices  (but  in  no  event  less  than  industry
practices).  Sublessee's  maintenance  programs  shall be  subject to review and
approval by Lessor and Sublessor.  Sublessee  shall,  if at any time  reasonably
requested by Lessor or Sublessor,  affix in a prominent position on each unit of
Equipment plates,  tags or other identifying labels showing the interest therein
of Lessor and Sublessor.

                                       89

<PAGE>

         (b) Sublessee will not,  without the prior consent of Sublessor,  affix
or install any accessory,  equipment or device on any Equipment if such addition
will impair the value,  originally  intended  function or use of such Equipment.
All additions,  repairs, parts, supplies,  accessories,  equipment,  and devices
furnished,  attached or affixed to any Equipment which are not readily removable
shall be made only in compliance with applicable law, including Internal Revenue
Service guidelines, shall be free and clear of all liens, encumbrances or rights
of others, and shall become the property of Lessor.  Sublessee will not, without
the prior written  consent of Sublessor and subject to such conditions as Lessor
or Sublessor may impose for its protection, affix or install any Equipment to or
in any other personal or real property.

         (c) Any alterations or  modifications to the Equipment that may, at any
time  during  the  term of this  Agreement,  be  required  to  comply  with  any
applicable law, rule or regulation shall be made at the expense of Sublessee.

VII.     STIPULATED LOSS VALUE:

         Sublessee  shall promptly and fully notify  Sublessor in writing if any
unit of  Equipment  shall  be or  become  worn  out,  lost,  stolen,  destroyed,
irreparably damaged in the reasonable determination of Sublessee, or permanently
rendered  unfit  for use  from  any  cause  whatsoever  (such  occurrence  being
hereinafter  called  "Casualty  Occurrences").  On the rental  payment date next
succeeding a Casualty  Occurrence  (the  "Payment  Date"),  Sublessee  shall pay
Sublessor the sum of (x) the  Stipulated  Loss Value of such unit  calculated in
accordance  with Annex D to the Master Lease,  which is  incorporated  herein by
reference as of the rental payment date next preceding such Casualty  Occurrence
("Calculation  Date");  and (y) all  rental  and  other  amounts  which  are due
hereunder as of the Payment Date. In addition to the amounts required to be paid
by Sublessee on any Rent Payment Date pursuant to the preceding  clauses (x) and
(y),  Sublessee shall also pay to Sublessor the amount of any swap breakage loss
incurred by Lessor and/or any Participant (as such term is hereinafter  defined)
as a result of or in connection  with such payment on such Rent Payment Date. As
used herein, "Swap Breakage Loss" shall include LIBOR and other funding breakage
costs,  if any, and may be determined by Lessor and any Participant by reference
to the Standard  International Swap Dealers Association  calculation for "Loss."
Upon  payment of all sums due  hereunder,  the term of this  Sublease as to such
unit shall  terminate  and  (except in the case of the loss,  theft or  complete
destruction of such unit) Lessor shall be entitled to recover possession of such
unit.

                                       90

<PAGE>


VIII.    LOSS OR DAMAGE:

         Sublessee  hereby  assumes  and shall bear the entire risk of any loss,
theft,  damage  to, or  destruction  of,  any unit of  Equipment  from any cause
whatsoever from the time the Equipment is shipped to Sublessee.

IX       INSURANCE.

         Sublessee agrees, at its own expense, to keep all Equipment insured for
such amounts as specified in the Equipment Schedules and against such hazards as
Lessor or Sublessor may require,  including,  but not limited to,  insurance for
damage  to or  loss  of such  Equipment  and  liability  coverage  for  personal
injuries,  death or property damage, with Lessor named as additional insured and
with a loss  payable  clause in favor of Lessor,  as its  interest  may  appear,
irrespective  of any breach of warranty  or other act or omission of  Sublessee.
All such policies shall be with companies, and on terms,  satisfactory to Lessor
and Sublessor.  Sublessee  agrees to deliver to Sublessor  evidence of insurance
satisfactory  to Lessor  and  Sublessor.  No  insurance  shall be subject to any
co-insurance   clause.   Sublessee   hereby   appoints   Lessor  as  Sublessee's
attorney-in-fact  to make  proof of loss and  claim for  insurance,  and to make
adjustments  with insurers and to receive  payment of and execute or endorse all
documents, checks or drafts in connection with payments made as a result of such
insurance  policies.  Any  expense  of Lessor  and  Sublessor  in  adjusting  or
collecting  insurance  shall  be  borne by  Sublessee.  Sublessee  will not make
adjustments  with  insurers  except (i) with respect to claims for damage to any
unit of Equipment where the repair costs do not exceed ten percent (10%) of such
unit's fair market value, or (ii) with Lessor's or Sublessor's  written consent.
Said policies shall provide that the insurance may not be altered or canceled by
the  insurer  until  after  thirty  (30)  days'  written  notice to  Lessor  and
Sublessor.  Sublessee may, at its option, apply proceeds of insurance,  in whole
or in part, to (i) repair or replace  Equipment or any portion thereof,  or (ii)
satisfy any obligation of Sublessee to Lessor or Sublessor hereunder.

X.       RETURN OF EQUIPMENT:

         (a)  Upon  any  expiration  or  termination  of this  Agreement  or any
Schedule, Sublessee shall promptly, at its own cost and expense: (i) perform any
testing and repairs  required to place the  affected  units of  Equipment in the
same condition and appearance as when received by Sublessee (reasonable wear and
tear excepted) and in good working order for their originally  intended purpose;
(ii) if deinstallation,  disassembly or crating is required, cause such units to
be  deinstalled,   disassembled  and  crated  by  an  authorized  manufacturer's
representative  or such other service person as is satisfactory  to Lessor;  and
(iii)  return such  units,  free and clear of all liens and  encumbrances,  to a
location within the continental United States as Lessor shall direct.

         (b)  Until  Sublessee  fully  has  complied  with the  requirements  of
Paragraph  (a)  above,   Sublessee's  Rent  payment  obligation  and  all  other
obligations   under  this   Agreement   shall   continue  from  month  to  month
notwithstanding  any  expiration  or  termination  of the  Term.  Sublessor  may
terminate  such  continued  leasehold  interest  upon ten (10)  days'  notice to

                                       91

<PAGE>

Sublessee.  In addition to these  rents,  Sublessor  shall have all of its other
rights and remedies available as a result of this nonperformance.

XI.      DEFAULT:

         (a)  Lessor or  Sublessor  may in writing  declare  this  Agreement  in
default ("Default") if: (1) Sublessee breaches its obligation to pay Rent or any
other  sum when due and  fails to cure the  breach  within  ten (10)  days;  (2)
Sublessee breaches any of its insurance  obligations under SECTION IX hereof, or
Sublessee  fails to comply with the  provisions  of SECTION  XXIII of the Master
Lease; (3) Sublessee  breaches any of its other obligations  hereunder and fails
to cure that breach within thirty (30) days after written  notice  thereof;  (4)
any  representation  or  warranty  made by  Sublessee  in  connection  with this
Agreement  shall be false or misleading in any material  respect;  (5) Sublessee
becomes insolvent or ceases to do business as a going concern; (6) any Equipment
is illegally  used;  (7) a petition is filed by or against  Sublessee  under any
bankruptcy or insolvency laws and, if such petition is filed against  Sublessee,
such petition is not dismissed within ninety (90) days; (8) Sublessee shall have
terminated its corporate existence,  consolidated with, merged into, or conveyed
or leased  substantially  all of its assets as an entirety  to any person  (such
actions being  referred to as an "Event"),  unless not less than sixty (60) days
prior to such Event: (x) such person is organized and existing under the laws of
the  United  States or any  state,  and  executes  and  delivers  to Lessor  and
Sublessor an agreement  containing an effective assumption by such person of the
due and punctual performance of this Sublease;  and (y) Lessor and Sublessor are
reasonably  satisfied as to the  creditworthiness  of such person; (9) effective
control of Sublessor's voting capital stock, issued and outstanding from time to
time, is not retained by the present  stockholders  (unless Sublessor shall have
provided  sixty  (60)  days'  prior  written  notice to  Lessor of the  proposed
disposition  of stock and Lessor shall have consented  thereto in writing).  Any
provision  of  this  Agreement  to  the  contrary  notwithstanding,  Lessor  and
Sublessor  may  exercise all rights and remedies  hereunder  independently  with
respect to each Schedule.

         (b) After  Default,  at the request of Lessor,  Sublessee  shall comply
with the provisions of SECTION X(a) hereof.  Sublessee hereby  authorizes Lessor
to enter,  with or without legal  process,  any premises  where any Equipment is
located and take possession  thereof.  Sublessee shall,  without further demand,
forthwith pay to Lessor (i) as liquidated  damages for loss of a bargain and not
as a  penalty,  the  Stipulated  Loss  Value  of the  Equipment  (calculated  in
accordance  with Annex D to the Master  Lease as of the Rent  Payment  date next
preceding the declaration of default), and (ii) all Rent and other sums then due
hereunder.  Lessor may,  but shall not be required  to,  sell the  Equipment  at
private or public  sale,  in bulk or in  parcels,  with or without  notice,  and
without  having the  Equipment  present at the place of sale; or Lessor may, but
shall not be required to, lease,  otherwise  dispose of or keep idle all or part
of the Equipment;  and Lessor may use Sublessee's premises for any or all of the
foregoing without liability for rent, costs, damages or otherwise.  The proceeds
of sale, lease or other  disposition,  if any, shall be applied in the following
order of  priorities:  (1) to pay all of Lessor's  costs,  charges and  expenses
incurred  in  taking,  removing,  holding,  repairing  and  selling,  leasing or
otherwise disposing of Equipment; then, (2) to the extent not previously paid by
Sublessee,  to pay Lessor  all sums due from  Sublessee  hereunder;  then (3) to
reimburse  to Sublessee  any sums  previously  paid by  Sublessee

                                       92

<PAGE>

as  liquidated  damages;  and (4) any surplus  shall be  remitted to  Sublessee.
Sublessee shall pay any deficiency in clauses (1) and (2) forthwith.

         (c) In addition  to the  foregoing  rights,  after  Default,  Lessor or
Sublessor may terminate the lease as to any or all of the Equipment.

         (d) The foregoing  remedies are cumulative,  and any or all thereof may
be  exercised in lieu of or in addition to each other or any remedies at law, in
equity,  or under statute.  Sublessee waives notice of sale or other disposition
(and the time and place thereof),  and the manner and place of any  advertising.
If permitted by law,  Sublessee  shall pay reasonable  attorney's  fees actually
incurred by Lessor and  Sublessor in enforcing  the  provisions of this Sublease
and any ancillary documents.  Waiver of any Default shall not be a waiver of any
other or subsequent default.

         (e) Any default under the terms of any other material agreement between
Sublessor  and  Sublessee  or  any  of  their  affiliates  giving  rise  to  the
termination of such other agreement may be declared by Sublessor a default under
this agreement.

XII.     ASSIGNMENT:

         (a) SUBLESSEE  SHALL NOT ASSIGN,  MORTGAGE,  SUBLET OR HYPOTHECATE  ANY
EQUIPMENT  OR THE  INTEREST OF  SUBLESSEE  HEREUNDER  WITHOUT THE PRIOR  WRITTEN
CONSENT OF SUBLESSOR.

         (b)  Sublessor may not,  without the consent of Sublessee,  assign this
Agreement or any Schedule, or the right to enter into any Schedule, such consent
not  to be  unreasonably  withheld.  In the  event  of a  permitted  assignment,
Sublessee  agrees that it will pay all Rent and other amounts payable under each
Schedule  to the  Sublessor  named  therein;  provided,  however,  if  Sublessee
receives written notice of an assignment from Sublessor,  Sublessee will pay all
Rent and other amounts  payable under any assigned  Schedule to such assignee or
as instructed by Sublessor. Each Schedule,  incorporating by reference the terms
and conditions of this  Agreement,  constitutes a separate  instrument of lease,
and the  Sublessor  named  therein  or its  assignee  shall  have all  rights as
"Sublessor"  thereunder  separately  exercisable  by  such  named  Sublessor  or
assignee as the case may be,  exclusively and  independently of Sublessor or any
assignee with respect to other Schedules  executed  pursuant  hereto.  Sublessee
further  agrees to  confirm  in writing  receipt  of a notice of  assignment  as
reasonably may be requested by assignee.

         (c)  Sublessee  acknowledges  that it has  been  advised  that  General
Electric Capital  Corporation is acting under the Master Lease for itself and as
agent  for  certain  third   parties  (each  being  herein   referred  to  as  a
"Participant" and,  collectively,  as the "Participants");  that the interest of
the Lessor in the Master Lease, the Equipment Schedules, related instruments and
documents  and/or the Equipment may be conveyed to, in whole or in part, and may
be used as security  for  financing  obtained  from,  one or more third  parties
without  the  consent  of  Sublessee  (the   "Syndication").   Sublessee  agrees
reasonably  to  cooperate  with  Lessor and  Sublessor  in  connection  with the
Syndication,  including  the  execution  and  delivery of such other  documents,

                                       93

<PAGE>

instruments,  notices, opinions,  certificates and acknowledgments as reasonably
may be required by Lessor, Sublessor or such Participant;  provided,  however in

XIV.     DISCLAIMER:

         SUBLESSEE  ACKNOWLEDGES  THAT IT HAS SELECTED THE EQUIPMENT WITHOUT ANY
ASSISTANCE  FROM LESSOR,  ITS AGENTS OR EMPLOYEES.  EXCEPT AS MAY BE PROVIDED IN

authorized  during the term of this Lease to assert and enforce,  at Sublessee's
sole cost and expense,  from time to time, in the name of and for the account of
Lessor,  Sublessor  and/or  Sublessee,  as their interests may appear,  whatever
claims and rights  Sublessor  or Lessor may have  against  any  Supplier  of the
Equipment.

XV.      REPRESENTATIONS AND WARRANTIES OF SUBLESSEE:

its present  business and operations,  including the  jurisdiction(s)  where the
Equipment is or is to be located.

         (b) The Documents have been duly authorized,  executed and delivered by
Sublessee and constitute  valid,  legal and binding  agreements,  enforceable in

remedies  therein  provided  may be  limited  under  applicable  bankruptcy  and
insolvency laws.

         (c) No approval,  consent or withholding of objections is required from
any governmental  authority or instrumentality with respect to the entry into or
performance  by  Sublessee  of the  Documents  except such as have  already been

         (d) The entry into and  performance  by Sublessee of the Documents will
not: (i) violate any judgment,  order, law or regulation applicable to Sublessee
or any provision of Sublessee's  articles of incorporation,  charter or by-laws;
or (ii)  result in any breach of,  constitute  a default  under or result in the
creation of any lien,  charge,  security  interest or other encumbrance upon any
Equipment  pursuant  to any  indenture,  mortgage,  deed of trust,  bank loan or
credit  agreement  or other  instrument  (other  than this  Agreement)  to which
Sublessee is a party.

         (e) There are no suits or proceedings pending or threatened in court or

in good standing and qualified as a foreign corporation in (i) each jurisdiction
in which the  Equipment  is or will be  located  and (ii) in such  jurisdictions
where Sublessee's  ownership or lease of property or the conduct of its business
requires it to be so qualified.

XVI.     COVENANTS OF SUBLESSEE:

         Sublessee covenants and agrees as follows:

         (a)  Promptly  upon any  officer or  director  of  Sublessee  obtaining
knowledge of any  condition or event which  constitutes a default or a potential
default  hereunder,  Sublessee  shall provide prompt written notice to Sublessor
specifying  such  condition  and what action  Sublessee is taking or proposes to
take with respect thereto.

         (b)  Sublessee  will  promptly  execute and deliver to  Sublessor  such
further  documents,  instruments  and assurances and take such further action as
Lessor or Sublessor from time to time may  reasonably  request in order to carry
out the intent and purpose of this  Sublease  and to  establish  and protect the
rights and  remedies  created or intended to be created in favor of Sublessor or
Lessor hereunder.

         (c) Sublessee will comply with all affirmative  and negative  covenants
set forth in Exhibits M and N to the Master Lease,  to the same extent as if set
forth herein.

         (d) Sublessee will not attach or  incorporate  any item of Equipment to
or in any other item of  equipment  or  personal  property  or to or in any real
property  in a manner  that gives rise to the  assertion  of any lien,  claim or
encumbrance  on such  item of  Equipment  by reason  of such  attachment  or the
assertion of a claim that such item of Equipment has become a fixture. Sublessee
hereby agrees that it will  purchase any such item of Equipment  which Lessor or
Sublessor  notifies Sublessee in writing is subject to the assertion of any such
lien, claim or encumbrance within ten (10) days of such notice.

         (e) The Equipment  will at all times be used for commercial or business
purposes.

         (f)  Sublessee  shall not take any action  that  would  cause a default
under this Sublease or the Master Lease or omit to take any action  necessary to
prevent a breach of this Sublease or the Master Lease.

XVII.    REPRESENTATIONS AND WARRANTIES OF SUBLESSOR:

         (a)  Sublessor  has  adequate  power and  capacity to enter  into,  and
perform  under,  this  Agreement  and  all  related  documents  (together,   the
"Documents") and is duly qualified to do business wherever necessary to carry on
its present  business and operations,  including the  jurisdiction(s)  where the
Equipment is or is to be located.

         (b) The Documents have been duly authorized,  executed and delivered by
Sublessor and constitute  valid,  legal and binding  agreements,  enforceable in
accordance  with their  terms,

                                       96

<PAGE>

except to the extent that the  enforcement of remedies  therein  provided may be
limited under applicable bankruptcy and insolvency laws.

         (c) No approval,  consent or withholding of objections is required from
any governmental  authority or instrumentality with respect to the entry into or
performance  by  Sublessor  of the  Documents  except such as have  already been
obtained.

         (d) There are no suits or proceedings pending or threatened in court or

Sublessor, which will have a material adverse effect on the ability of Sublessor
to fulfill its obligations under this Agreement.

         (e)  Sublessor has not received a Notice of Default on the Master Lease
from Lessor and, to  Sublessor's  knowledge  after the  exercise of  Sublessor's
commercially  reasonable  best  efforts to  investigate  the same,  no  material
default has  occurred on the Master Lease with  respect to the  Equipment  which
could not be cured by the giving of notice or  undertaking  of other actions not
material to the market value of the Equipment taken as a whole.

XVIII.   COVENANTS OF SUBLESSOR:

         Sublessor covenants and agrees as follows:

         (a)  Sublessor  shall at all time  perform  its  obligations  under the
Master Lease with respect to the Equipment, except such covenant shall not apply
to the extent such default is due to actions or failure to act by Sublessee.

         (b)  Sublessor  shall  notify  Sublessee  in  writing  of any notice of
default which it receives from the Lessor with respect to the Equipment:  (1) if
with respect to a failure to pay rent or any other sum when due,  such notice to
be delivered  to  Sublessee no later than 2 days after  receipt of the notice of
default  received by  Sublessor,  and (2) if with respect to any other notice of
default,  such notice to be  delivered  to Sublessee no later than 10 days after
receipt of the notice of default received by Sublessor

XIX.     OWNERSHIP FOR TAX PURPOSES, GRANT OF SECURITY INTEREST; USURY SAVINGS:

         (a) For income tax purposes,  Lessor and Sublessor will treat Sublessee
as the owner of the Equipment.  Accordingly, Lessor and Sublessor will not claim
any tax benefits available to an owner of the Equipment.

         (b)  Sublessee  hereby  acknowledges  that Lessor has a first  security
interest in the Equipment, together with all additions, attachments, accessions,
accessories  and accessions  thereto whether or not furnished by the Supplier of
the Equipment and any and all substitutions,


                                       97

<PAGE>

replacements  or  exchanges  therefor,  and any and all  insurance  and/or other
proceeds of the  property in and  against  which a security  interest is granted
hereunder.

         (c) It is the  intention  of the  parties  hereto  to  comply  with any
applicable usury laws to the extent that any Equipment Schedule is determined to
be subject to such laws;  accordingly,  it is agreed that,  notwithstanding  any
provision  to the contrary in any  Equipment  Schedule or this  Sublease,  in no
event shall any Equipment  Schedule require the payment or permit the collection
of interest in excess of the maximum amount  permitted by applicable law. If any
such excess interest is contracted for,  charged or received under any Equipment
Schedule or this  Sublease,  or in the event that all of the  principal  balance
shall be prepaid, so that under any of such circumstances the amount of interest
contracted for, charged or received under any Equipment Schedule or the Sublease
shall exceed the maximum amount of interest permitted by applicable law, then in
such event: (i) the provisions of this paragraph shall govern and control,  (ii)
neither Sublessee nor any other person or entity now or hereafter liable for the
payment  hereof  shall be  obligated  to pay the amount of such  interest to the
extent  that it is in excess of the  maximum  amount of  interest  permitted  by
applicable  law,  (iii) any such excess which may have been  collected  shall be
either applied as a credit against the then unpaid principal balance or refunded
to Sublessee,  at the option of the  Sublessor,  and (iv) the effective  rate of
interest  shall be  automatically  reduced to the maximum  lawful  contract rate
allowed under applicable law as now or hereafter  construed by the courts having
jurisdiction  thereof.  It is further  agreed  that  without  limitation  of the
foregoing,  all calculations of the rate of interest  contracted for, charged or
received  under any  Equipment  Schedule or the Sublease  which are made for the
purpose of  determining  whether such rate exceeds the maximum  lawful  contract
rate,  shall be made, to the extent  permitted by applicable law, by amortizing,
prorating, allocating and spreading in equal parts during the period of the full
stated  term of the  indebtedness  evidenced  hereby,  all  interest at any time
contracted for,  charged or received from Sublessee or otherwise by Sublessor in
connection with such  indebtedness;  provided,  however,  that if any applicable
state law is  amended or the law of the United  States of America  preempts  any
applicable  state law,  so that it becomes  lawful  for  Sublessor  to receive a
greater interest per annum rate than is presently allowed,  the Sublessee agrees
that, on the effective date of such amendment or preemption, as the case may be,
the lawful  maximum  hereunder  shall be increased  to the maximum  interest per
annum rate allowed by the amended  state law or the law of the United  States of
America.

XX.      END OF SUBLEASE PURCHASE OPTION:

         So long as (i) no default exists under the Sublease or the Master Lease
and (ii) the Term of the  Sublease  and the  Master  Lease has not been  earlier
terminated,  Sublessee may at the  expiration of the Term of the Sublease,  upon
one hundred eighty (180) days' prior written  notice to Sublessor,  purchase all
(but not less than all) of the Equipment  described in any Schedule on an AS IS,
WHERE IS BASIS without recourse to or warranty from Sublessor or lessor, express
or  implied,  for a  purchase  price of $1.00  payable  to  Sublessor  (plus all
applicable sales taxes).  The payment shall be due and payable on the expiration
of the Term of the Sublease and the Master Lease.

XXI.     MISCELLANEOUS:

         (a) SUBLESSEE HEREBY  UNCONDITIONALLY WAIVES ITS RIGHTS TO A JURY TRIAL
OF ANY  CLAIM OR CAUSE OF ACTION  BASED  UPON OR  ARISING  OUT OF,  DIRECTLY  OR
INDIRECTLY,  THIS SUBLEASE,  ANY OF THE RELATED DOCUMENTS,  ANY DEALINGS BETWEEN
SUBLESSEE  AND  SUBLESSOR OR THE LESSOR  RELATING TO THE SUBJECT  MATTER OF THIS
TRANSACTION OR ANY RELATED  TRANSACTIONS,  AND/OR THE RELATIONSHIP THAT IS BEING
ESTABLISHED  BETWEEN  SUBLESSEE  AND  SUBLESSOR.  The  scope of this  waiver  is
intended to be all encompassing of any and all disputes that may be filed in any
court (including,  without limitation,  contract claims, tort claims,  breach of
duty claims,  and all other  common law and  statutory  claims).  THIS WAIVER IS
IRREVOCABLE MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND
THE WAIVER SHALL APPLY TO ANY SUBSEQUENT  AMENDMENTS,  RENEWALS,  SUPPLEMENTS OR
MODIFICATIONS TO THIS SUBLEASE, ANY RELATED DOCUMENTS, OR TO ANY OTHER DOCUMENTS
OR AGREEMENTS  RELATING TO THIS TRANSACTION OR ANY RELATED  TRANSACTION.  In the
event of litigation, this Agreement may be filed as a written consent to a trial
by the court.

         (b) Any  cancellation  or  termination  by  Sublessor,  pursuant to the
provision of this Sublease, any Schedule, supplement or amendment hereto, or the
sublease of any Equipment  hereunder,  shall not release Sublessee from any then
outstanding obligations to Sublessor hereunder.

         (c) All Equipment shall at all times remain personal property of Lessor
regardless of the degree of its annexation to any real property and shall not by
reason of any  installation  in, or  affixation  to, real or  personal  property
become a part  thereof.  Sublessee  shall obtain and deliver to Sublessor (to be
recorded at Lessee's expense) from any person having an interest in the property
where the  Equipment  is to be  located,  waivers  of any lien,  encumbrance  or
interest which such person might have or hereafter  obtain or claim with respect
to the Equipment.

         (d) Time is of the essence of this  Agreement.  Sublessor's  failure at
any time to require  strict  performance  by Sublessee of any of the  provisions
hereof shall not waive or diminish Sublessor's right thereafter to demand strict
compliance therewith.

         (e)  Sublessee  agrees,  upon  Sublessor's   request,  to  execute  any
instrument  necessary  or expedient  for filing,  recording  or  perfecting  the
interest of Sublessor or Lessor.

         (f) All  notices  required to be given  hereunder  shall be in writing,
personally delivered,  delivered by overnight courier service, sent by facsimile
transmission (with  confirmation of receipt),  or sent by certified mail, return
receipt requested, addressed to the other party at its respective address stated
above or,  with  respect to the  Lessor,  in the  Master  Lease or at such other
address as such party shall from time to time  designate in writing to the other
party, and shall be effective from the date of receipt.

         (g) This Sublease and the Schedule,  including the Equipment  Schedules
and the  schedules  to the  Master  Lease,  which  are  incorporated  herein  by
reference,  constitute the entire agreement  between the parties with respect to
the  subject  matter  hereof  and shall not be  amended or altered in any manner
except by a document  in writing  executed  by both  parties.  NO  VARIATION  OR
MODIFICATION  OF  THIS  AGREEMENT  OR ANY  WAIVER  OF ANY OF ITS  PROVISIONS  OR
CONDITIONS,  SHALL BE VALID  UNLESS  IN  WRITING  AND  SIGNED  BY AN  AUTHORIZED
REPRESENTATIVE  OF THE PARTIES HERETO.  Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction  shall, as to such jurisdiction,
be ineffective to the extent of such  prohibition  or  unenforceability  without
invalidating  the  remaining  provisions  hereof,  and any such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.

         (h) The  representations,  warranties and covenants of Sublessee herein
shall be deemed to survive the closing  hereunder.  The obligations of Sublessee
which accrue during the term of this  Agreement and  obligations  which by their
express  terms  survive the  termination  of this  Agreement,  shall survive the
termination of this Agreement.

         (i) In case of a failure of Sublessee  to comply with any  provision of
this Agreement,  Sublessor shall have the right, but shall not be obligated,  to
effect such  compliance,  in whole or in part; and all moneys spent and expenses
and  obligations  incurred or assumed by Sublessor in effecting such  compliance
(together  with interest  thereon at the rate specified in Paragraph (j) of this
Section) shall constitute  additional Rent due to Sublessor within five (5) days
after  the  date  Sublessor  sends  notice  to  Sublessee   requesting  payment.
Sublessor's  effecting  such  compliance  shall not be a waiver  of  Sublessee's
default.

         (j) Any Rent or other  amount  not paid to  lessor  when due  hereunder
shall bear interest,  both before and after any judgment or termination  hereof,
at the lesser of eighteen percent (18%) per annum or the maximum rate allowed by
law.

         (k) Any  provisions  in this  Agreement  and any Schedule  which are in
conflict  with any  statute,  law or  applicable  rule shall be deemed  omitted,
modified or altered to conform thereto.

         (l) So  long  as no  Default  shall  have  occurred  and be  continuing
hereunder,  and conditioned  upon Sublessee  performing all of the covenants and
conditions  hereof,  as  to  claims  of  Sublessor  or  persons  claiming  under
Sublessor,  Sublessee  shall  peaceably  and quietly  hold,  possess and use the
Equipment during the Term of this Agreement  subject to the terms and conditions
hereof.

         (m) Whether or not any Equipment is leased  hereunder,  Sublessee shall
pay upon demand as  additional  Rent  hereunder  all  reasonable  and  necessary
documented  transaction  expenses  including,  but not limited  to,  expenses of
counsel,  due diligence,  appraisals,  lien searches,  Uniform  Commercial  Code
and/or Estoppel/Waiver Agreement filing fees, and field audits.

<PAGE>

           security  interests,  claims,  and restrictions,  and that the Shares
           constitute  all of the  outstanding  capital  stock  of the  Company.
           Seller will cause the transfer to SAVVIS of good and marketable title
           to the Shares at Closing,  free and clear of all security  interests,
           claims,  and  restrictions.  Seller  represents that it has the legal
           capacity  and  authority to execute and deliver  this  Agreement,  to
           perform its obligations hereunder, and to consummate the transactions
           contemplated hereby.

           5.2 The  tangible  and  intangible  property  owned and leased by the
           Company and listed or described  on Schedule  5.2 hereto  constitutes
           all of the  property  and  property  rights  owned and  leased by the
           Company and all of the property  and property  rights that in any way
           relate to, are used in, or are  necessary for the operation of the IP
           Network of the  Company  in the  manner  and to the extent  presently
           conducted or planned.  Further, the Company does not own or lease any
           tangible or  intangible  property that is unrelated to the IP Network
           and not  mentioned in Schedule  5.2.  Should the Company own or lease
           property not related to the IP Network, the Parties shall endeavor to
           cause such  property to be  returned  to the Seller,  and any charges
           incurred or revenues generated in connection with such property shall
           be allocated to the appropriate  Party as if such property were owned
           or leased by the Seller.

           5.3 SAVVIS and Seller  shall take all  reasonable  efforts to jointly
           prepare,  within fifteen days after the Effective Date, or as soon as
           practical  thereafter,  a revised  list of the  property set forth on
           Schedule 5.2. This revised list shall supersede the attached Schedule
           5.2 and shall include any assets purchased or acquired by the Company
           after October 31, 1999 but before the Effective  Date and  comprising
           part of the IP Network.  The parties shall negotiate in good faith to
           finalize the revised Schedule 5.2 and shall provide to each other any
           information or records reasonably necessary to finalize it.

6.         FURTHER ASSURANCE

           From and after  Closing,  the Parties  shall do such acts and execute
           such documents and instruments as may be reasonably  required to make
           effective the  transactions  contemplated  hereby.  In the event that
           consents,  approvals, other authorizations or other acts contemplated
           by this  Agreement  have not been fully  effected as of Closing,  the
           parties will continue after Closing,  without further  consideration,
           to use their best efforts to carry out such transactions. However, in
           the  event  that  certain  approvals,  consents  or  other  necessary
           documentation  cannot  be  secured,   then  the  Party  having  legal
           responsibility,  ownership,  or  control  shall  act on behalf of the
           other Party, without further  consideration,  to effect the essential
           intention   of  the  Parties   with   respect  to  the   transactions
           contemplated by this Agreement.

7.         SURVIVAL OF CERTAIN PROVISIONS

           To the extent that any  provision  of this  Agreement  shall not have
           been  performed at Closing it shall  survive and remain in full force
           and effect notwithstanding Closing.

2.       THE NETWORKS AND QUALITY OF SERVICE STANDARDS

         2.1.  SAVVIS agrees to use the Acquired  Network  Facilities to provide
               (or to cause the  SAVVIS  Subsidiaries  to  provide)  to  Bridge,
               Affiliates  of  Bridge or any party  making  use of the  Networks

               thereof:

                    (a)  a   global   office-automation    network,    providing
                         connectivity  between  the  offices of Bridge  (the "OA
                         NETWORK"),

                    (b)  a  global  data  collection  network  (the  "COLLECTION
                         NETWORK") and

                    (c)  a global data distribution  network (the  "DISTRIBUTION
                         NETWORK"),   such   description   being  given  without
                         limitation on Bridge's use of such network  services as
                         are  provided by SAVVIS,  which shall be referred to in
                         this  Agreement  collectively  as  the  "NETWORKS"  and
                         individually as a "NETWORK."

         2.2.  Each Network shall be operated, managed and maintained by SAVVIS.
               SAVVIS may,  but shall not be  obligated  to, use  facilities  of
               SAVVIS other than the Acquired Network  Facilities to provide all
               or any part of any Network. Beginning on the first anniversary of
               the  Effective  Date  and  thereafter,   each  Network  shall  be
               operated,  managed  and  maintained  by SAVVIS  according  to the
               Quality of Service  Standards  set forth in Schedule  2.2 hereof,
               and SAVVIS shall be responsible for monitoring the performance of
               the Networks with respect to the Quality of Service Standards and
               shall provide Bridge with monthly reports of such performance. If
               the Quality of Service  Standards  are not met with  respect to a
               particular  Installation  Site  in any  month,  Bridge  shall  be
               entitled to receive,  upon  written  request by Bridge  within 30
               days  of  its  receipt  of  the   performance   report  for  such
               Installation  Site for such  month,  a credit in the  amount  set
               forth on Schedule  2.2  attached  hereto,  which  amount shall be
               deemed to be one month's charges  applicable to such Installation
               Site under this Agreement  with respect to such month;  provided,
               however,  that Bridge shall not be entitled to such credit to the
               extent that the failure to meet the Quality of Service  Standards
               with  respect to such  Installation  Site is due to (i) an act or
               omission of Bridge or a Bridge Subsidiary or a vendor or customer
               of Bridge

                                       5
<PAGE>

               or a Bridge  Subsidiary  or (ii)  equipment  or software  used by
               Bridge and not  provided  by SAVVIS.  Not more than one credit of
               one month's charges shall be given for a particular  Installation
               Site for a  particular  month.  The Quality of Service  Standards
               shall not apply to the  provision of Local Access  Facilities  in
               countries in which the products and services of Bridge and Bridge
               Subsidiaries are provided through third-party  distributors.  For
               all purposes of this Agreement,  including without limitation the
               determination  of an Event of Default by SAVVIS,  the  Quality of
               Service Standards applicable to a particular Installation Site in
               any month shall be deemed to have been met unless Bridge,  within
               30  days  of its  receipt  of the  performance  report  for  such
               Installation Site for such month, requests in writing a credit as
               set forth above with respect to such  Installation  Site for such
               month.

         2.3.  SAVVIS agrees that, for the term of this  Agreement,  the network
               operations  centers for the  Networks  shall be managed by Bridge
               under the Technical Services Agreement;  provided,  however, that
               SAVVIS  shall  not be  restricted  from  building,  managing  and
               operating  one  or  more  network  operations  centers  for  such
               portions  of the SAVVIS  Backbone or other  operations  of SAVVIS
               that are not used to provide the Networks to Bridge.

         2.4.  [Intentionally omitted.]

         2.5.  Unless  otherwise  mutually agreed by the parties,  each Addendum
               providing  for the  provision of  Additional  Network  Facilities
               shall have a term of three years.  Such Addendum may also include
               provisions with respect to the level of redundancy to be provided
               and the Quality of Service  Standards to apply to such Additional
               Network Facilities.  In providing  Additional Network Facilities,
               SAVVIS   agrees  to  use  its  best   efforts  to  expedite   the
               provisioning  of  the  circuits  for  such   Additional   Network
               Facilities in those  instances in which SAVVIS is responsible for
               provisioning such circuits.

         2.6.  Throughout  the  term of this  Agreement,  SAVVIS  shall  use its
               commercially  reasonable  best  efforts to  continue  to meet the
               requests  of Bridge to  enhance  the total  capacity,  geographic
               extension  and  performance  quality  of  the  Networks,  and  to
               maintain  its  research  and   development   effort  at  a  level
               appropriate  to sustain  the  ability of Bridge to compete on the
               basis of the quality of the Networks.

         2.7.  The parties  acknowledge  that SAVVIS intends to replace  certain
               existing  routers  among the  Acquired  Network  Facilities  (the
               "REPLACED   ROUTERS")  with  new  equipment  promptly  after  the
               Effective  Date.  It is the  intention  of the  parties  that the
               Replaced  Routers will be  re-deployed at  Installation  Sites at
               which one or more 56 Kbps ports or 64 Kbps ports will be provided
               by SAVVIS using  Additional  Network  Facilities  as set forth in
               Section  3.1  hereof.  SAVVIS  agrees  to  manage  the use of its
               inventory of routers in order to re-deploy the maximum

                                       6
<PAGE>


               number of Replaced Routers as is commercially reasonable. So long
               as Replaced Routers are available for re-deployment during the 18
               months  following the Effective  Date,  SAVVIS agrees not to make
               any bulk  purchases  of  additional  routers  without  the  prior
               written  consent  of  Bridge,  which  will  not  be  unreasonably
               withheld.   Upon  the  expiration  of  18  months  following  the
               Effective  Date,  the  parties  shall  determine  the  number  of
               Replaced Routers that the parties mutually agree are likely to be
               so  re-deployed  within the  succeeding  12 months.  All Replaced
               Routers  that  are not  reasonably  likely  to be so  re-deployed
               within such  12-month  period shall be  purchased  from SAVVIS by
               Bridge at a price per  Replaced  Router  equal to the average net
               book value as of the  Effective  Date of all routers  included in
               the Acquired Network Facilities.

3.       RATES AND CHARGES

         3.1.  Bridge  shall pay  SAVVIS  for the  Networks  using the  Acquired
               Network Facilities and Additional Network Facilities according to
               the rates and charges set forth in Schedule 3.1 hereof.

         3.2.  The parties  recognize that certain  savings might be obtained by
               consolidating  the  multiple  Local  Access  Facilities  that are
               provided at such building locations on the Effective Date. In the
               event  that  SAVVIS   consolidates   the  multiple  Local  Access
               Facilities at one or more of such building  locations and obtains
               cost savings as a result thereof, the parties will mutually agree
               within 30 days  following  such  consolidation  on the  manner in
               which such savings shall be shared between SAVVIS and Bridge. Any
               reduction  pursuant to this Section  shall not affect the Minimum
               Annual Commitment.

         3.3.  For any Installation  Site to which SAVVIS is providing  services
               both under  this  Agreement  and the  Telerate  Network  Services
               Agreement,  the rates and charges applicable to such Installation
               Site  under this  Agreement  shall be  one-half  of the rates and
               charges that would  otherwise be applicable to such  Installation
               Site under this Agreement.

4.       STRATEGIC ADVISORY COMMITTEE

         4.1.  Within 30 days after the Effective Date,  SAVVIS and Bridge shall
               each appoint three senior  executives to the "STRATEGIC  ADVISORY
               COMMITTEE," and one outside consultant shall be jointly appointed
               by both parties. Any fees and expenses of such outside consultant
               incurred in  connection  with service on the  Strategic  Advisory
               Committee  shall be shared  equally  by SAVVIS and  Bridge.  Each
               party  shall  have  the  right  to  change  any  or  all  of  its
               representatives  on the Strategic Advisory Committee upon written
               notice to the other  party.  A quorum of the  Strategic  Advisory
               Committee  shall consist of four members,  provided that at least
               two members appointed by each party are present. The Chair of the
               Strategic  Advisory  Committee shall be designated by Bridge from
               among the seven members of the Committee.

                                       7
<PAGE>

         4.2.  The  mission  of the  Strategic  Advisory  Committee  shall be to
               review the performance of the Networks, to serve as forum for the
               consideration and discussion of issues raised by either SAVVIS or
               Bridge  with  respect  to the  Networks,  and to  discuss  issues
               related  to the  future  development  of the data  transport  and
               Internet Protocol backbone operations of SAVVIS in the context of
               the relationship of SAVVIS and Bridge.

         4.3.  The  Strategic  Advisory  Committee  shall  meet with  reasonable
               frequency, at the call of the Chair.

         4.4.  The Strategic  Advisory Committee shall have reasonable access to
               the Chief Executive  Officer and the Board of Directors of SAVVIS
               to raise areas of concern to the Committee under this Agreement.

         4.5.  SAVVIS agrees to use its commercially  reasonable best efforts to
               comply  with  the   recommendations  of  the  Strategic  Advisory
               Committee   regarding   performance  issues  arising  under  this
               Agreement.

5.       INVOICES

         5.1.  The  amounts  due to SAVVIS  from  Bridge  for the  installation,
               operation,  management  and  maintenance of the Networks shall be
               billed monthly in advance.  All items on invoices not the subject
               of a bona  fide  dispute  shall be  payable  by  Bridge in United
               States  currency  within 30 days from the date of  receipt of the
               invoice.  All  amounts  not in dispute  are  subject to  interest
               charges of 1-1/2  percent  that will accrue  daily on all amounts
               not paid within 30 days of the date of receipt of the invoice.

         5.2.  At any time and from time to time,  Bridge may, by written notice
               to SAVVIS,  have one or more Installation  Sites removed from the
               Networks.  Each  monthly  invoice  from  SAVVIS to  Bridge  shall
               reflect a  reduction  in the  amount  charged  to Bridge  for the
               Networks  resulting from any such removal of Installation  Sites.
               In the case of any  Installation  Site  removed from the Acquired
               Network Facilities, such reduction shall be the sum of:

                    (a)  the  actual  cost  of  the  Local   Access   Facilities
                         connecting  the  Acquired  Network  Facilities  to such
                         Installation Site,  effective as of such time as SAVVIS
                         is no longer required to pay such costs, and

                    (b)  the amounts set forth on Schedule 5.2 attached  hereto,
                         which are deemed to be one month's  charges  applicable
                         to such  Installation  Site under this  Agreement  with
                         respect to such month during the first  Agreement Year,
                         according  to  connection  speed  at such  Installation
                         Site,  effective  as of such time as such  Installation
                         Site is disconnected from the Networks.

               receipts,  state and local  surcharges,  value  added and similar
               taxes,  charges or levies lawfully  levied by a duly  constituted
               taxing   authority   against  or  upon  the   Networks.   In  the
               alternative,  Bridge  shall  provide  SAVVIS  with a  certificate
               evidencing  Bridge's  exemption  from payment of or liability for
               such taxes. All other taxes, charges or levies,  including any ad
               valorem,  income,  franchise,  privilege or  occupation  taxes of
               SAVVIS shall be paid by SAVVIS.

         5.4.  Bona fide disputes  concerning  invoices shall be referred to the
               parties' respective representatives who are authorized to resolve
               such matters.  Any amount to which Bridge is entitled as a result
               of the resolution of a billing dispute shall be credited promptly
               to Bridge's account.  Any amount to which SAVVIS is entitled as a
               result  of the  resolution  of a  billing  dispute  shall be paid
               promptly to SAVVIS.

         5.5.  Against  the  amounts   owed  by  Bridge  to  SAVVIS  under  this
               Agreement, Bridge shall have the right to offset any amounts owed
               by SAVVIS to Bridge under this Agreement,  the Technical Services
               Agreement, or otherwise, including without limitation any amounts
               paid by Bridge on behalf of SAVVIS under  guarantees by Bridge of
               obligations of SAVVIS.

6.       TERM AND EXTENSIONS

         6.1.  This  Agreement  shall  commence on the Effective  Date and shall
               continue  in full force and effect for the  Initial  Term  unless
               terminated or extended in accordance with the provisions hereof.

         6.2.  The term of this  Agreement  may be  extended  by Bridge  for one
               additional  five-year  period by giving SAVVIS written notice not
               less than one year before the scheduled expiration of the Initial
               Term.

         6.3.  Upon the  termination  of this  Agreement in accordance  with its
               scheduled  expiration or by Bridge  pursuant to Section 7, SAVVIS
               will  continue to provide the  Networks  in  accordance  with the
               terms  and  conditions   herein  (excluding  the  Minimum  Annual
               Commitment)  for a period of up to five years after the effective
               date  of  termination  (the  "TRANSITION  PERIOD").   During  the
               Transition  Period,  Bridge  shall pay  SAVVIS for the use of the
               Networks  at the rates in effect  for third  party  customers  of
               SAVVIS at the effective  date of  termination.  If Bridge has not
               completely  transitioned  from its use of the Networks  after the
               Transition  Period,  SAVVIS will  provide the Networks at SAVVIS'
               then current list rates.  SAVVIS and its successor will cooperate
               with  Bridge  until  Bridge has  completely  migrated  to another
               provider.

7.       TERMINATION BY BRIDGE

         7.1.  An "EVENT OF DEFAULT BY SAVVIS" shall be deemed to occur if:

                                       9
<PAGE>

                    (a)  SAVVIS has  failed to a  material  degree to perform or
                         comply with or has  violated  to a material  degree any
                         material  representation,  warranty, term, condition or
                         obligation of SAVVIS under this  Agreement,  and SAVVIS
                         has failed to cure such failure or violation  within 60
                         days after receiving notice thereof from Bridge; or

                    (b)  SAVVIS   becomes  the   subject  of  a   voluntary   or
                         involuntary bankruptcy,  insolvency,  reorganization or
                         liquidation  proceeding,  makes an  assignment  for the
                         benefit  of   creditors,   or  admits  in  writing  its
                         inability to pay debts when due; or

                    (c)  an Event of Default by SAVVIS occurs under the Telerate
                         Network Services Agreement.

         7.2.  Bridge shall have the right to terminate this Agreement,  with no
               liability to SAVVIS other than for charges  (less any  applicable
               credits) for the Networks provided prior to such termination, if:

                    (a)  Bridge provides  written notice to SAVVIS,  at any time
                         after the ninth  anniversary of the Effective  Date, of
                         Bridge's  intent to terminate,  such  termination to be
                         effective not less than one year  following the date of
                         such notice; or

                    (b)  Bridge provides 10 days written notice of its intent to
                         terminate  in the  event  that an Event of  Default  by
                         SAVVIS occurs.

         7.3.  For  purposes  of  Section  7.1(a),  if the  Quality  of  Service
               Standards  are not met with respect to a particular  Installation
               Site in any  month,  SAVVIS  shall be deemed to have  cured  such
               failure  within 60 days if the Quality of Service  Standards  are
               met  with  respect  to such  Installation  Site in the  following
               month.  A failure of the Quality of Service  Standards  to be met
               shall not constitute an Event of Default or give Bridge the right
               to  terminate  this  Agreement to the extent that such failure is
               due to (i) an act or omission of Bridge or a Bridge Subsidiary or
               a vendor or  customer  of Bridge or a Bridge  Subsidiary  or (ii)
               equipment or software  used by Bridge and not provided by SAVVIS.
               The parties acknowledge and agree that the failure of the Quality
               of  Service  Standards  to be met  with  respect  to one or  more
               Installation  Sites  in one or more  months  may,  but  does  not
               necessarily,  constitute a failure by SAVVIS to a material degree
               to perform or comply with,  or a violation  to a material  degree
               of, any material  representation,  warranty,  term,  condition or
               obligation of SAVVIS under this Agreement.

         7.4.  As provided in Section 2.2,  for all purposes of this  Agreement,
               including  without  limitation the  determination  of an Event of
               Default by SAVVIS  under  this  Section,  the  Quality of Service
               Standards  applicable  to a particular  Installation  Site in any
               month shall be deemed to have been met unless  Bridge,  within 30

                                       10
<PAGE>



               days  of  its  receipt  of  the   performance   report  for  such
               Installation Site for such month, requests in writing a credit as
               set forth in Section 2.2 with respect to such  Installation  Site
               for such month.

8.       TERMINATION BY SAVVIS

         8.1.  SAVVIS shall have the right to terminate this Agreement if:

                    (a)  Bridge  has failed to pay any  invoice  that is not the
                         subject  of a bona fide  dispute  within 60 days of the
                         date  on  which  such  payment  is due and  SAVVIS  has
                         provided Bridge with written notice  thereof,  provided
                         that Bridge  shall have a further 30 days from the time
                         it receives  such notice from SAVVIS of  nonpayment  to
                         cure any such default;

                    (b)  SAVVIS provides 10 days written notice of its intent to
                         terminate  in the  event  that  Bridge  has  failed  to
                         perform or comply  with or has  violated  any  material
                         representation, warranty, term, condition or obligation
                         of Bridge under this  Agreement,  and Bridge has failed
                         to cure such failure or violation  within 60 days after
                         receiving notice thereof from SAVVIS;

                    (c)  Bridge   becomes  the   subject  of  a   voluntary   or
                         involuntary bankruptcy,  insolvency,  reorganization or
                         liquidation  proceeding,  makes an  assignment  for the
                         benefit  of   creditors,   or  admits  in  writing  its
                         inability to pay debts when due; or

                    (d)  SAVVIS  becomes  entitled  to  terminate  the  Telerate
                         Network  Services   Agreement  pursuant  to  the  terms
                         thereof.

         8.2.  Notwithstanding  the provisions of Section  8.1(b) above,  SAVVIS
               shall  not  have the  right to  terminate  this  Agreement  under
               Section  8.1(b)  solely  for a failure  by Bridge to  perform  or
               comply with, a violation by Bridge of, the  obligations of Bridge
               under Section 15  (Confidentiality)  of this  Agreement,  without
               prejudice, however, to such rights as SAVVIS may have pursuant to
               such  Section and to such rights and remedies to which SAVVIS may
               be entitled,  at law or in equity,  as the result of an actual or
               threatened breach by Bridge of such Section.

9.       ACCEPTANCE OF ADDITIONAL NETWORK FACILITIES

         9.1.  Upon the  installation  of Additional  Network  Facilities at any
               Installation  Site,  SAVVIS shall  conduct  appropriate  tests to
               establish  that such  Additional  Network  Facilities  perform in
               accordance  with  mutually   agreed  upon   acceptance   criteria
               ("ACCEPTANCE  CRITERIA")  set  forth in the  applicable  Addendum
               entered into pursuant to Section 2.4, and shall  promptly  inform
               Bridge  of such  test  results.  If test  results  show  that the
               Additional  Network  Facilities are performing in accordance with
               the  Acceptance  Criteria,  Bridge  shall be deemed to accept the
               Additional   Network   Facilities   at  the   Installation   Site
               immediately.

                                       11
<PAGE>

         9.2.  If  SAVVIS'  tests  establish  that  newly  installed  Additional
               Network  Facilities  at the  Installation  Site do not perform in
               accordance  with the mutually  agreed upon  Acceptance  Criteria,
               then  SAVVIS  shall  immediately  and  diligently  exert its best
               efforts  to  bring  the  Additional  Network  Facilities  at such
               Installation  Site into compliance.  SAVVIS shall not bill Bridge
               for the Additional  Network  Facilities at such Installation Site
               until  the  test  results  show  that  the   Additional   Network
               Facilities  are  performing  in  accordance  with the  Acceptance
               Criteria.

         9.3.  Upon repair or  restoration  of any part of the Networks,  SAVVIS
               shall conduct  appropriate  tests to establish  that the Networks
               perform  in  accordance  with  mutually  agreed  upon  Acceptance
               Criteria and shall promptly inform Bridge of such test results.

10.      RIGHTS AND OBLIGATIONS OF BRIDGE

         10.1.    SITE PREPARATION.  For the installation of Additional  Network
                  Facilities,  Bridge  shall,  at its own  expense,  provide all
                  necessary preparations of each Installation Site in accordance
                  with  the  requirements  to be  mutually  agreed  upon  by the
                  parties and set forth in an Addendum hereto,  including inside
                  wiring,  demarcation  extension  and rack  mount  accessories.
                  Bridge shall ensure that Bridge-provided  equipment is on-site
                  by the scheduled  installation  date. If SAVVIS is required to
                  reschedule  the  installation  of  Bridge-provided   equipment
                  because it is not on-site by the scheduled  installation date,
                  Bridge shall pay SAVVIS to redispatch installation personnel.

         10.2.    PROPER USE OF NETWORKS.

                  10.2.1.  Bridge shall use any equipment  provided by SAVVIS in
                           connection  with the Networks in accordance  with its
                           documentation,  which documentation shall be provided
                           by SAVVIS at no additional  charge.  Unless otherwise
                           provided   herein,   upon  the  termination  of  this
                           Agreement   Bridge  shall  surrender  to  SAVVIS  the
                           equipment  provided by SAVVIS, in good working order,
                           ordinary wear and tear excepted.

                  10.2.2.  Bridge  shall be liable for  damages to the  Networks
                           caused by the negligence or willful acts or omissions
                           of Bridge's officers,  employees, agents, contractors
                           or customers,  for loss through theft or vandalism of
                           the  Networks  at  the  Installation  Site,  and  for
                           damages  to  the  Networks   caused  by  the  use  of
                           equipment or supplies  not provided  hereunder or not
                           otherwise authorized by SAVVIS.

                  10.2.3.  Bridge shall neither  permit nor assist others to use
                           the  Networks  for any  purpose  other  than that for
                           which  they  are  intended,  nor fail to  maintain  a
                           suitable  environment  specified  by  SAVVIS  in  the
                           applicable  schedule,  nor alter, tamper with, adjust
                           or  repair  the   Networks.   Any  such   alteration,
                           tampering,  adjustment  or  repair  by  Bridge  shall
                           relieve SAVVIS from any

                                       12
<PAGE>


                           liability  or  obligation  hereunder  (including  any
                           warranty  or  indemnity  obligation)  relating to the
                           affected  Network,  and  Bridge  shall be  liable  to
                           SAVVIS for any  documented  direct costs  incurred by
                           SAVVIS as a result of such actions.

         10.3.    ABUSE OR FRAUDULENT USE OF NETWORKS. Bridge shall not abuse or
                  fraudulently  use the  Networks  or use the  Networks  for any
                  unauthorized or illegal purposes, and shall neither permit nor
                  assist others to do so, including but not limited to:

                  (a)  obtaining  or  attempting   to  obtain   service  by  any
                       fraudulent means or device to avoid payment; or

                  (b)  accessing,  altering or  destroying  any  information  of
                       another  party  by any  fraudulent  means or  device,  or
                       attempting to do so; or

                  (c)  using the Networks so as to interfere with the use of the
                       SAVVIS  network by other SAVVIS  customers or  authorized
                       users  or in  violation  of  law  or in  support  of  any
                       unlawful act;

                  (d)  using  the  Networks  for  voice  communications  over  a
                       private  network in  jurisdictions  where such use is not
                       allowed; or

                  (e)  using  the   Networks   in  a  manner   contrary   to  or
                       inconsistent  with such acceptable use policies as SAVVIS
                       may adopt and publish from time to time  consistent  with
                       industry standards.

                  Notwithstanding  the  provisions of Section 8, upon the breach
                  of this Section 10.3 by Bridge, SAVVIS shall have the right to
                  terminate  this  Agreement  with respect to all or part of the
                  Networks immediately upon written notice to Bridge.

         10.4.    COVENANT NOT TO COMPETE.

                  10.4.1.  As  an  inducement  to  SAVVIS  to  enter  into  this
                           Agreement, which Bridge acknowledges is of benefit to
                           it,  and  in   consideration   of  the  promises  and
                           representations   of  SAVVIS  under  this  Agreement,
                           Bridge  covenants  and agrees that during the term of
                           this  Agreement  and  for  a  period  of  five  years
                           thereafter,  neither Bridge nor any of its successors
                           or assigns will,  directly or indirectly,  engage in,
                           or have  any  interest  in any  other  person,  firm,
                           corporation  or other entity engaged in, any business
                           activities  anywhere in the world competitive with or
                           similar  or  related  to  the  packet-data  transport
                           network  services   provided  by  SAVVIS  under  this
                           Agreement; provided, however, that (i) Bridge and the
                           Bridge  Subsidiaries shall be free to continue to use
                           the Call Assets and the satellite  networks currently
                           used by Bridge,  until such Call Assets or  satellite
                           networks  have been  acquired by SAVVIS or the SAVVIS
                           Subsidiaries pursuant to the Master Establishment and
                           Transition

                           Agreement,  and  (ii)  Bridge  shall  be free to make
                           passive  investments  in securities of companies that
                           provide network  services in competition  with SAVVIS
                           which,  in the  case of any such  security,  does not
                           constitute  more than ten percent  (10%) of the total
                           outstanding amount of such security.

                  10.4.2.  If any court or  tribunal of  competent  jurisdiction
                           shall refuse to enforce one or more of the  covenants
                           in  this   Section   10.4   because  the  time  limit
                           applicable  thereto  is  deemed  unreasonable,  it is
                           expressly understood and agreed that such covenant or
                           covenants  shall not be void but that for the purpose
                           of such  proceedings  such time  limitation  shall be
                           deemed  to be  reduced  to the  extent  necessary  to
                           permit the enforcement of such covenant or covenants.

                  10.4.3.  If any court or  tribunal of  competent  jurisdiction
                           shall  refuse to enforce any or all of the  covenants
                           in this Section 10.4 because,  taken  together,  they
                           are more  extensive  (whether as to geographic  area,
                           scope of business or otherwise)  than is deemed to be
                           reasonable,  it is  expressly  understood  and agreed
                           between  the  parties  hereto  that such  covenant or
                           covenants  shall not be void but that for the purpose
                           of  such  proceedings  the   restrictions   contained
                           therein  (whether  as to  geographic  area,  scope of
                           business or otherwise)  shall be deemed to be reduced
                           to the extent  necessary to permit the enforcement of
                           such covenant or covenants.

                  10.4.4.  Bridge specifically  acknowledges and agrees that the
                           foregoing  covenants are commercially  reasonable and
                           reasonably  necessary  to protect  the  interests  of
                           SAVVIS  hereunder.  Bridge hereby  acknowledges  that
                           SAVVIS and its  successors  and  assigns  will suffer
                           irreparable  and  continuing  harm to the extent that
                           any of the  foregoing  covenants is breached and that
                           legal  remedies  would be  inadequate in the event of
                           any such breach.

11.      RIGHTS AND OBLIGATIONS OF SAVVIS

         11.1.    PROVISION OF THE NETWORKS.  SAVVIS shall operate, maintain and
                  manage  the  Networks  at the  Installation  Sites  using  the
                  Acquired Network  Facilities in accordance with the Quality of
                  Service Standards and other terms of this Agreement, including
                  all Addenda hereto.

         11.2.    REPRESENTATIONS AND WARRANTIES.

                  11.2.1.  [Intentionally omitted.]

                  11.2.2.  SAVVIS hereby  represents and warrants that the terms
                           hereof do not conflict in any respect whatsoever with
                           any   SAVVIS   tariff  on  file   with  the   Federal
                           Communications  Commission or other  regulatory body.
                           If, during the term of this  Agreement,  SAVVIS shall
                           file a contract specific tariff

                                       14
<PAGE>


                           governing the Networks or any portion  thereof,  such
                           tariff  filing  shall be  consistent  in all respects
                           with the terms of this  Agreement,  and SAVVIS  shall
                           give Bridge 10 days advance  written notice of making
                           such a tariff  filing  and of filing  any  subsequent
                           modifications thereto.

                  11.2.3.  THE  FOREGOING  WARRANTIES  ARE IN LIEU OF ALL  OTHER
                           WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED
                           WARRANTIES  OF  MERCHANTABILITY  AND  FITNESS  FOR  A
                           PARTICULAR PURPOSE.

         11.3.    So  long  as  Bridge  is the  beneficial  owner  of 20% of the
                  outstanding voting securities of SAVVIS Parent,  SAVVIS Parent
                  shall not,  without the prior written consent of Bridge,  take
                  any action or otherwise enter into any agreement,  arrangement
                  or understanding, including without limitation the creation or
                  issuance  of any  class of stock  or  other  security,  or any
                  agreement with any shareholder of SAVVIS Parent, the effect of
                  which would be to provide  any  shareholder  of SAVVIS  Parent
                  with any voting or registration  rights superior to the voting
                  or  registration  rights of Bridge,  other than as required by
                  law.

         11.4.    SAVVIS acknowledges that the occurrence of Event of Default by
                  SAVVIS,  arising  from either (i) a failure of the Networks to
                  meet  Quality  of  Service  Standards  or (ii) a total loss to
                  Bridge of the use of the  Networks,  could  cause  irreparable
                  harm to  Bridge,  the  amount  of which  may be  difficult  to
                  determine,  thus  potentially  making  any remedy at law or in
                  damages  inadequate.  SAVVIS,  therefore,  agrees  that Bridge
                  shall  have  the  right to  apply  to any  court of  competent
                  jurisdiction  for injunctive  relief upon the occurrence of an
                  Event of  Default  by  SAVVIS  or the  occurrence  of an event
                  which, with the passage of time or the giving of notice, could
                  become  an  Event  of  Default  by  SAVVIS  and for any  other
                  appropriate  relief.  This right  shall be in  addition to any
                  other  remedy  available  to Bridge in law or  equity.  SAVVIS
                  further  agrees  that,  upon  the  occurrence  of an  Event of
                  Default by SAVVIS,  SAVVIS shall pay to Bridge,  as liquidated
                  damages and not as a penalty, an amount equal to the lesser of
                  (a) the aggregate  amounts paid by Bridge to SAVVIS under this
                  Agreement  during  the six  months  preceding  such  Event  of
                  Default by SAVVIS or (b) $50,000,000;  provided, however, that
                  Bridge may recover  liquidated damages under this Section only
                  for an Event of Default by SAVVIS that occurs (i) prior to any
                  Event of Default by SAVVIS for which Bridge or Telerate or any
                  Bridge  Subsidiary  or any  Telerate  Subsidiary  has  claimed
                  liquidated  damages  under this  Section or under the Telerate
                  Network Services Agreement or under any Local Network Services
                  Agreement  or  under  any  Telerate  Local  Network   Services
                  Agreement,  or (ii)  more than 36  months  following  the most
                  recent Event of Default by SAVVIS for which Bridge or Telerate
                  or any  Bridge  Subsidiary  or  any  Telerate  Subsidiary  has
                  claimed  liquidated  damages  under this  Section or under the
                  Telerate Network Services Agreement or under any Local Network
                  Services   Agreement  or  under  any  Telerate  Local  Network
                  Services Agreement.

12.      LIMITATIONS OF LIABILITY

         12.1.    Subject to Section 11.4,  neither party shall be liable to the
                  other  for  indirect,  incidental,  consequential,  exemplary,
                  reliance  or  special  damages,  including  damages  for  lost
                  profits, regardless of the form of action whether in contract,
                  indemnity,  warranty,  strict  liability  or  tort,  including
                  negligence  of any kind with  respect to the Networks or other
                  conduct under this Agreement.

         12.2.    Nothing  contained in this Section shall limit either  party's
                  liability  to  the  other  for  (a)  willful  or   intentional
                  misconduct, including fraud, or (b) injury or death, or damage
                  to  tangible  real  or  tangible   personal  property  or  the
                  environment,  when  proximately  caused by SAVVIS' or Bridge's
                  negligence or that of their respective agents,  subcontractors
                  or  employees.  Nothing  contained in this Section shall limit
                  SAVVIS'  intellectual  property  indemnification   obligations
                  under  Section  16.1 or Bridge's  indemnification  obligations
                  with respect to a breach of Section 10.3.

13.      EQUIPMENT AND SOFTWARE NOT PROVIDED BY SAVVIS

         13.1.    SAVVIS  shall  not  be  responsible   for  the   installation,
                  operation or maintenance of equipment or software not provided
                  by it under this  Agreement,  nor shall SAVVIS be  responsible
                  for the  transmission or reception of information by equipment
                  or software  not  provided by SAVVIS  hereunder.  In the event
                  that Bridge uses  equipment or software not provided by SAVVIS
                  hereunder  in a  manner  that  impairs  Bridge's  use  of  the
                  Networks,  Bridge  shall not be excused  from payment for such
                  use and SAVVIS shall not be responsible for any failure of the
                  Networks  to meet the Quality of Service  Standards  resulting
                  from the use of such  equipment  or software  by Bridge.  Upon
                  notice from SAVVIS that the equipment or software not provided
                  by SAVVIS  under  this  Agreement  is  causing or is likely to
                  cause  hazard,  interference  or service  obstruction,  Bridge
                  shall eliminate the likelihood of such hazard, interference or
                  service obstruction.

         13.2.    Notwithstanding the foregoing,  SAVVIS shall, at no additional
                  charge, provide all interface  specifications for the Networks
                  reasonably requested by Bridge. SAVVIS shall, upon the receipt
                  of appropriate  specifications  from Bridge,  inform Bridge of
                  the  compatibility  with  the  Networks  of any  equipment  or
                  software that Bridge proposes to use in connection  therewith,
                  the effects,  if any, of the use of such equipment or software
                  on the quality,  operating  characteristics  and efficiency of
                  the Networks,  and the effects, if any, of the Networks on the
                  operating characteristics and efficiency of any such equipment
                  or software.

14.      PROPRIETARY RIGHTS; LICENSE

         14.1.    SAVVIS hereby grants to Bridge and the Bridge  Subsidiaries  a
                  non-exclusive   and   non-transferable   license  to  use  all
                  programming  and software  necessary for Bridge and the Bridge
                  Subsidiaries to use the Networks.  Such license is granted

                                       16
<PAGE>


                  for the  term of  this  Agreement  for  the  sole  purpose  of
                  enabling  Bridge  and  the  Bridge  Subsidiaries  to  use  the
                  Networks.

         14.2.    All title and property rights (including intellectual property
                  rights) to the Networks (including associated  programming and
                  software) are and shall remain with SAVVIS or the  third-party
                  providers  thereof  to  SAVVIS.  Bridge  shall not  (except as
                  permitted by applicable law) attempt to examine,  copy, alter,
                  reverse  engineer,  decompile,  disassemble,  tamper  with  or
                  otherwise misuse the Networks, programming and software.

15.      CONFIDENTIALITY

         15.1.    During  the term of this  Agreement  and for a period  of five
                  years  from  the  date  of  its   expiration  or   termination
                  (including  all  extensions  thereof),  each  party  agrees to
                  maintain in strict  confidence all  Confidential  Information.
                  Neither  party shall,  without  prior  written  consent of the
                  other party,  use the other party's  Confidential  Information
                  for any purpose other than for the  performance  of its duties
                  and  obligations,  and the exercise of its rights,  under this
                  Agreement.   Each  party  shall  use,   and  shall  cause  all
                  authorized   recipients  of  the  other  party's  Confidential
                  Information  to use,  the same  degree of care to protect  the
                  other party's  Confidential  Information as it uses to protect
                  its own  Confidential  Information,  but in any event not less
                  than a reasonable degree of care.

         15.2.    Notwithstanding  Section  15.1,  either party may disclose the
                  Confidential  Information  of the  other  party  to:  (a)  its
                  employees  and the  employees,  directors  and officers of its
                  Affiliates  as  necessary  to implement  this  Agreement;  (b)
                  employees,  agents or  representatives  of the other party; or
                  (c) other persons (including counsel, consultants,  lessors or
                  managers of  facilities  or  equipment  used by such party) in
                  need of access to such  information for purposes  specifically
                  related  to  either   party's   responsibilities   under  this
                  Agreement,   provided  that  any  disclosure  of  Confidential
                  Information  under  clause  (c) shall be made only upon  prior
                  written  approval  of  the  other  party  and  subject  to the
                  appropriate  assurances that the recipient of such information
                  shall hold it in strict confidence.

         15.3.    Upon the  request of the party  having  proprietary  rights to
                  Confidential  Information,  the  party in  possession  of such
                  information  shall  promptly  return it (including any copies,
                  extracts and  summaries  thereof,  in whatever form and medium
                  recorded) to the  requesting  party or, with the other party's
                  written  consent,  shall  promptly  destroy it and provide the
                  other party with written certification of such destruction.

         15.4.    Either party may request in writing that the other party waive
                  all or any portion of the requesting party's  responsibilities
                  relative to the other party's Confidential  Information.  Such
                  waiver request shall identify the affected information and the
                  nature of the proposed  waiver.  The  recipient of the request
                  shall respond within a

                  reasonable time and, if it determines, in its sole discretion,
                  to grant the requested  waiver,  it will do so in writing over
                  the signature of an employee authorized to grant such request.

         15.5.    Bridge  and  SAVVIS   acknowledge   that  any   disclosure  or
                  misappropriation  of Confidential  Information in violation of
                  this  Agreement  could cause  irreparable  harm, the amount of
                  which may be difficult to determine,  thus potentially  making
                  any  remedy  at  law or in  damages  inadequate.  Each  party,
                  therefore, agrees that the other party shall have the right to
                  apply to any  court  of  competent  jurisdiction  for an order
                  restraining  any breach or  threatened  breach of this Section
                  and for any other appropriate  relief.  This right shall be in
                  addition to any other remedy available in law or equity.

         15.6.    A party requested or ordered by a court or other  governmental
                  authority  of  competent   jurisdiction  to  disclose  another
                  party's Confidential  Information shall notify the other party
                  in  advance  of any such  disclosure  and,  absent  the  other
                  party's  consent to such  disclosure,  use its best efforts to
                  resist,  and to assist  the  other  party in  resisting,  such
                  disclosure.  A party providing  another  party's  Confidential
                  Information to a court or other  governmental  authority shall
                  use  its  best  efforts  to  obtain  a  protective   order  or
                  comparable  assurance  that the  Confidential  Information  so
                  provided will be held in confidence and not further  disclosed
                  to any other person, absent the owner's prior consent.

         15.7.    The  provisions  of  Section  15.1  above  shall  not apply to
                  reasonably  necessary  disclosures  in or in  connection  with
                  filings  under any  securities  laws,  regulatory  filings  or
                  proceedings,  financial  disclosures  which in the good  faith
                  judgment  of  the  disclosing   party  are  required  by  law,
                  disclosures   required  by  court  or  tribunal  or  competent
                  jurisdiction,  or disclosures that may be reasonably necessary
                  in connection  with the sale of securities or the  performance
                  or  enforcement  of this  Agreement or any of the  obligations
                  hereof;  provided,  however, that if the receiving party would
                  otherwise  be required  to refer to or describe  any aspect of
                  this  Agreement  in any of the  preceding  circumstances,  the
                  receiving party shall use its reasonable  efforts to take such
                  steps as are available  under such  circumstances  (such as by
                  providing a summary or  synopsis) to avoid  disclosure  of the
                  financial    terms   and   conditions   of   this   Agreement.
                  Notwithstanding  any  provisions  of  this  Agreement  to  the
                  contrary,  either party may disclose the terms and  conditions
                  of this  Agreement  in the  course of a due  diligence  review
                  performed in connection  with  prospective  debt  financing or
                  equity  investment by, or a sale to, a third party, so long as
                  the persons  conducting such due diligence  review have agreed
                  to maintain the  confidentiality of such disclosure and not to
                  use such  disclosure  for any purpose other such due diligence
                  review.

16.      INDEMNIFICATIONS

         16.1.    SAVVIS shall defend,  settle,  or otherwise  manage at its own
                  cost and expense any claim or action  against Bridge or any of
                  its  directors,  officers,  employees or assigns for actual or
                  alleged infringement by the Networks of any patent, copyright,
                  trademark,  trade secret or similar  proprietary  right of any
                  third party,  except to the extent that such actual or alleged
                  infringement   arises   from  (i)  such   actual  or   alleged
                  infringement by the Acquired Network Facilities on or prior to
                  the  Effective  Date or (ii) an act or omission of Bridge or a
                  Bridge  Subsidiary  or a vendor  or  customer  of  Bridge or a
                  Bridge  Subsidiary  or (iii)  equipment  or  software  used by
                  Bridge  and  not  provided  by  SAVVIS  or  (iv)  services  or
                  equipment  provided  by or  on  behalf  of  Bridge  under  the
                  Technical  Services  Agreement.  Bridge  shall  notify  SAVVIS
                  promptly  in  writing  of any such  claim  or suit  and  shall
                  cooperate  with SAVVIS in a reasonable  way to facilitate  the
                  settlement  or  defense  thereof.  SAVVIS  further  agrees  to
                  indemnify  and hold Bridge  harmless  from and against any and
                  all liabilities and damages (whether incurred as the result of
                  a judicial decree or a settlement), and the costs and expenses
                  associated  with any claim or action of the type identified in
                  this Section (including reasonable attorneys' fees).

         16.2.    If,  as a  consequence  of a  claim  or  action  of  the  kind
                  described in Section  16.1,  SAVVIS' or Bridge's use of all or
                  part of any Network is enjoined,  SAVVIS shall,  at its option
                  and  expense,  either:  (a)  procure  for  Bridge the right to
                  continue using the affected  Network;  (b) modify such Network
                  so  that   they  are   non-infringing,   provided   that  such
                  modification  does not affect the  intended use of the Network
                  as contemplated  hereunder. If SAVVIS does not take any of the
                  actions  described  in  clauses  (a) or (b),  then  Bridge may
                  terminate  the affected  portion of such  Network,  and SAVVIS
                  shall refund to Bridge any prepaid charges therefor.

         16.3.    Subject to Section 12, Bridge will defend,  indemnify and hold
                  harmless SAVVIS or any of its directors,  officers,  employees
                  or assigns  from and against all loss,  liability,  damage and
                  expense, including reasonable attorneys' fees, caused by:

                  (a)   claims  for  libel,  slander,  invasion  of  privacy  or
                        infringement   of   copyright,   and   invasion   and/or
                        alteration  of private  records or data arising from any
                        information,  data  or  messages  transmitted  over  the
                        Networks by Bridge; and

                  (b)   claims for  infringement of patents arising from the use
                        by Bridge  of  equipment  and  software,  apparatus  and
                        systems not provided  hereunder in  connection  with the
                        Networks; and

                  (c)   the  violation of any  representations,  warranties  and
                        covenants made by Bridge in this Agreement.

         16.4.    Subject to Section 12, SAVVIS will defend,  indemnify and hold
                  harmless Bridge or any of its directors,  officers,  employees
                  or assigns  from and against all loss,  liability,  damage and
                  expense, including reasonable attorneys' fees, caused by:

                  (a)   claims for  infringement of patents arising from the use
                        by SAVVIS  of  equipment  and  software,  apparatus  and
                        systems not provided by SAVVIS  hereunder in  connection
                        with  the  Networks  (other  than any  Acquired  Network
                        Facilities); and

                  (b)   the  violation of any  representations,  warranties  and
                        covenants made by SAVVIS in this Agreement.

17.      DISPUTES

         17.1.    Except  as   expressly   provided  in  Schedule  4.1  of  this
                  Agreement, the resolution of any and all disputes arising from
                  or  in  connection  with  this  Agreement,  whether  based  on
                  contract, tort, statute or otherwise,  including disputes over
                  arbitrability  and disputes in connection with claims by third
                  persons  ("DISPUTES")  shall be  exclusively  governed  by and
                  settled in accordance  with the provisions of this Section 17.
                  The  foregoing   shall  not  preclude   recourse  to  judicial
                  proceedings to obtain injunctive, emergency or other equitable
                  relief to enforce the provisions of this Agreement,  including
                  specific  performance,  and  to  decide  such  issues  as  are
                  required to be resolved in  determining  whether to grant such
                  relief. Resolution of Disputes with respect to claims by third
                  persons shall be deferred until any judicial  proceedings with
                  respect thereto are concluded.

         17.2.    The parties  hereby  agree to submit all  Disputes to rules of
                  arbitration of the American  Arbitration  Association  and the
                  Missouri  Uniform  Arbitration  Act (the  "RULES")  under  the
                  following  provisions,  which shall be final and binding  upon
                  the  parties,  their  successors  and  assigns,  and  that the
                  following  provisions  constitute a binding arbitration clause
                  under applicable law. Either party may serve process or notice
                  on the other in any  arbitration  or  litigation in accordance
                  with the notice  provisions  hereof.  The parties agree not to
                  disclose any information  regarding any Dispute or the conduct
                  of any arbitration hereunder,  including the existence of such
                  Dispute or such  arbitration,  to any  person or entity  other
                  than such employees or representatives of such party as have a
                  need to know.

         17.3.    Either party may commence proceedings hereunder by delivery of
                  written  notice  providing  a  reasonable  description  of the
                  Dispute to the other,  including a reference to this provision
                  (the "DISPUTE NOTICE").  Either party may initiate arbitration
                  of  a  Dispute  by   delivery  of  a  demand   therefor   (the
                  "ARBITRATION  DEMAND")  to the other  party not sooner than 60
                  calendar days after the date of delivery of the Dispute Notice
                  but at any time thereafter. The arbitration shall be conducted
                  in St. Louis, Missouri.

                                       20
<PAGE>

         17.4.    The arbitration  shall be conducted by three  arbitrators (the
                  "ARBITRATORS"),  one of whom shall be selected by Bridge,  one
                  by  SAVVIS,  and the third by  agreement  of the other two not
                  later than 10 days  after  appointment  of the first two,  or,
                  failing such agreement, appointed pursuant to the Rules. If an
                  Arbitrator  becomes  unable to  serve,  a  successor  shall be
                  selected  or  appointed  in  the  same  manner  in  which  the
                  predecessor Arbitrator was appointed.

         17.5.    The arbitration shall be conducted pursuant to such procedures
                  as the parties may agree or, in the absence of or failing such
                  agreement,   pursuant  to  the  Rules.   Notwithstanding   the
                  foregoing,  each party  shall  have the right to  inspect  the
                  books and  records  of the  other  party  that are  reasonably
                  related to the  Dispute,  and each party shall  provide to the
                  other,  reasonably  in advance of any  hearing,  copies of all
                  documents  which such party intends to present in such hearing
                  and the names and addresses of all witnesses  whose  testimony
                  such party intends to present in such hearing.

         17.6.    All hearings shall be conducted on an expedited schedule,  and
                  all proceedings shall be confidential. Either party may at its
                  expense make a stenographic record thereof.

         17.7.    The Arbitrators  shall complete all hearings not later than 90
                  calendar days after the Arbitrators' selection or appointment,
                  and shall make a final award not later than 30  calendar  days
                  thereafter.  The  Arbitrators  shall  apportion  all costs and
                  expenses of the Arbitration,  including the Arbitrators'  fees
                  and  expenses  of experts  ("ARBITRATION  COSTS")  between the
                  prevailing and non-prevailing  parties as the Arbitrators deem
                  fair and reasonable. In circumstances where a Dispute has been
                  asserted or defended  against on grounds that the  Arbitrators
                  deem manifestly  unreasonable,  the Arbitrators may assess all
                  Arbitration  Costs  against the  non-prevailing  party and may
                  include in the award the prevailing  party's  attorneys'  fees
                  and expenses in connection with any and all proceedings  under
                  this Section 17.

         17.8.    Either party may assert appropriate  statutes of limitation as
                  a defense in  arbitration;  provided,  that upon delivery of a
                  Dispute  Notice  any  such  statute  shall be  tolled  pending
                  resolution hereunder.

         17.9.    Pending the resolution of any dispute or  controversy  arising
                  under this  Agreement,  the parties shall  continue to perform
                  their respective obligations  hereunder,  and SAVVIS shall not
                  discontinue,  disconnect  or in any  other  fashion  cease  to
                  provide  all or any  substantial  portion of the  Networks  to
                  Bridge unless otherwise directed by Bridge. This Section shall
                  not apply where (a) Bridge is in default under this  Agreement
                  or (b) the dispute or controversy  between the parties relates
                  to harm to the Networks  allegedly caused by Bridge and Bridge
                  does not immediately cease and desist from the activity giving
                  rise to the dispute or controversy.

18.      FORCE MAJEURE

         18.1.    In no event shall  either party be liable to the other for any
                  failure  to  perform  hereunder  that  is due to  war,  riots,
                  embargoes, strikes or other concerted acts of workers (whether
                  of a party  hereto or of  others),  casualties,  accidents  or
                  other   causes  to  the  extent  that  such  failure  and  the
                  consequences  thereof  are  reasonably  beyond the control and
                  without the fault or negligence of the party claiming  excuse.
                  Each party shall, with the cooperation of the other party, use
                  reasonable  efforts to  mitigate  the extent of any failure to
                  perform and the adverse consequences thereof.

         18.2.    If SAVVIS cannot promptly provide a suitable  temporary SAVVIS
                  alternative  to  all  or  part  of a  Network  subject  to  an
                  interruption  in  connection  with  the  existence  of a force
                  majeure  condition,  Bridge  may, at its option and at its own
                  cost, contract with one or more third parties for the affected
                  portion of the Network for the shortest commercially available
                  period likely to cover the reasonably expected duration of the
                  interruption,  and  may  suspend  SAVVIS'  provision  of  such
                  affected  portion  for such  period.  SAVVIS  shall not charge
                  Bridge for the  affected  portion  thus  suspended  during the
                  period of  suspension.  SAVVIS shall  resume  provision of the
                  suspended  portion  of  the  Network  upon  the  later  of the
                  termination   or  expiration  of  Bridge's   legally   binding
                  commitments under contracts with third parties for alternative
                  services  or the  cessation  or remedy  of the  force  majeure
                  condition.

         18.3.    In the event that a force majeure condition shall continue for
                  more than 60 days,  Bridge may cancel the affected  portion of
                  the Network with no further liability to SAVVIS other than for
                  obligations  incurred  with respect to such  affected  portion
                  prior to the occurrence of the force majeure condition.

         18.4.    The consequences  arising from existence and continuation of a
                  force majeure  condition,  including  without  limitation  any
                  interruption of the Networks and the exercise by Bridge of its
                  rights   under  this  Section  18,  shall  be  deemed  not  to
                  constitute   a  breach   by   either   party   hereto  of  any
                  representations,  warranties or covenants  hereunder and shall
                  not be grounds  for the  exercise of any  remedies  under this
                  Agreement, including without limitation remedies under Section
                  2.2 or Section 7, other than those  specified  in this Section
                  18.

                                  SCHEDULE 2.2
                          QUALITY OF SERVICE STANDARDS

1.       Starting  one year  from  the  Effective  Date,  the  Acquired  Network
         Facilities and Additional  Network Facilities that are connected to the
         St.  Louis  hub  where  Bridge  houses  the data  distributed  over the
         Distribution  Network (the "ST.  LOUIS HUB") by fully  redundant  paths
         shall be covered by Quality of Service Standards  outlined below. These
         provisions shall be applicable to Installation  Sites performing within
         the bandwidth  limitations set forth in Section 7.2 of Schedule 3.1 or,
         with respect to the SAVVIS  Backbone,  to be agreed upon,  and shall be
         measured in performance relative to the St. Louis Hub.

2.       For  the  SAVVIS  Backbone   supporting  the  Collection   Network  and
         Distribution Network:

         (a)  There shall not be less than 99.99% availability to any SAVVIS POP
              supporting  Installation Sites during each one month period during
              the Market Hours  applicable to the POP connected to the St. Louis
              Hub.

         (b)  The average  round-trip  terrestrial  latency period to SAVVIS POP
              locations  supporting  Installation  Sites  during each  one-month
              period shall not exceed:

              (i)    75 milliseconds within the United States,

              (ii)   250 milliseconds to Australia,  Eastern Asia,  Europe,  and
                     North America,

              (iii)  425  milliseconds  to  all  other  areas,  including  South
                     America, Middle East, Africa, New Zealand and India.

3.       For Installation Sites, network availability shall be measured in terms
         of server upstream  connectivity during Market Hours for each one-month
         period.  Resultant  availability to the Installation Sites shall be not
         less than 99.99% based on the following criteria:

         (a)  All server  disconnects  will be considered  as potential  network
              outages.

         (b)  Disconnects which are attributed to bandwidth limitations, process
              failures,  and server  faults will be  eliminated  from the sample
              population.

         (c)  Remaining disconnects that reflect total outage conditions on both
              redundant  pieces of the  network  shall be  considered  a network
              outage to the Installation  Site. The time duration of the network
              outage shall be used to determine the availability percentage.

                                       26

3.       SAVVIS will continue to monitor  performance of the acquired  Bridge OA
         Network.  Performance  problems with specific OA sites will be resolved
         jointly by Bridge and SAVVIS.

4.       CREDIT AMOUNTS

         Amounts to be credited if the Quality of Service  Standards are not met
         with respect to a particular Installation Site in any month shall be as
         follows, plus (other than in Distributor  Countries) the actual charges
         for  Installation  Site  Local  Access  Facilities,  permanent  virtual
         circuits or other means for connecting  such  Installation  Site to the
         SAVVIS POP:

9.       DETERMINATION OF RATES AND CHARGES AFTER FIRST AGREEMENT YEAR

         9.1. For each Agreement Year following the first Agreement Year of this
              Agreement,  the  rates  and  charges  for  the  Networks  and  any
              Additional Network Facilities shall be mutually agreed upon by the
              parties from time to time in an Addendum to this  Agreement in the
              manner set forth in Section 1.2 of this Agreement;  provided that,
              in Europe or Asia where the Additional  Network  Facilities charge
              does not include a Backbone component, the charge for any Backbone
              circuit in

                                       37
<PAGE>

              the  Distribution  Network  that is not used  exclusively  for the
              carriage of Bridge traffic under this  Agreement  shall be charged
              to Bridge  according to the actual cost to SAVVIS of such backbone
              circuit  multiplied  by the  proportionate  megabit  usage of such
              circuits by Bridge under this Agreement as of the Effective  Date,
              and  further  multiplied  by [*].  If the  parties  fail to  reach
              agreement  on any such  Addendum  prior to the  expiration  of the
              Addendum then in effect, the rates and charges shall be determined
              by binding arbitration, as follows:

         9.2. The arbitration shall be conducted by a single arbitrator  jointly
              selected by the parties,  who shall be an attorney experienced and
              knowledgeable  in the tariffs  and  pricing of  telecommunications
              services (the "ARBITRATOR"). If the parties are unable to agree on
              the selection of the Arbitrator  within 30 days,  either party may
              apply to the United States District Court for the Eastern District
              of Missouri or to the Circuit  Court of St.  Louis  County for the
              appointment of the Arbitrator.

               (b)  Within 10 days following the  appointment of the Arbitrator,
                    each party shall submit to the Arbitrator  such party's best
                    and final offer for the rates and charges to be set forth in
                    such Addendum.

               (c)  The  Arbitrator  must  select  the offer of one party or the
                    other as being closer to the  Arbitrator's own assessment of
                    what an independent vendor would charge for services similar
                    in nature and volume to those to be covered by such Addendum
                    (the "INDEPENDENT VENDOR PRICE").

               (d)  The decision of the Arbitrator shall be final and binding on
                    the parties and shall be  incorporated  in this Agreement as
                    an Addendum hereto.

               (e)  Each  party  shall  bear  its own  costs in  conducting  the
                    arbitration, and the non-prevailing party shall pay the fees
                    and expenses of the Arbitrator.

         9.3. At the time any Addendum is entered into with respect to the rates
              and charges for any POP Site, the amount charged to Bridge for the
              T-1  ports at such  Installation  Site  shall be not more than the
              Independent   Vendor  Price  for  providing  such  ports  at  such
              Installation  Site,  as  mutually  agreed  by  the  parties  or as
              determined by the Arbitrator  under Sections 9.1 and 9.2,  reduced
              by [*]of the excess,  if any, of the Independent  Vendor Price for
              providing  such ports over the actual cost to SAVVIS of  providing
              such ports at such Installation Site.

               (d)  With respect to the fourth,  fifth and sixth Agreement Years
                    during the Initial Term, an amount equal to 80% of the total
                    amount  paid by Bridge  and all Bridge  Subsidiaries  during
                    such Agreement Year to SAVVIS, SAVVIS Subsidiaries and third
                    parties  for  Internet  Protocol  backbone  and  other  data
                    transport services;

               (e)  With  respect  to  the  seventh,  eighth,  ninth  and  tenth
                    Agreement  Years during the Initial Term, an amount equal to
                    60% of the  total  amount  paid by  Bridge  and  all  Bridge

                    backbone and other data transport services.

         10.3. With respect to the fourth Agreement Year and each Agreement Year
               thereafter,  SAVVIS shall have the right, at reasonable times and
               on  reasonable  notice,  but not more often than once  during any
               Agreement  Year, to audit the books and records of Bridge and the

1.       CONTRACT DOCUMENTS AND DEFINITIONS

                           "NETWORK."

         2.2.     Each Network  shall be  operated,  managed and  maintained  by
                  SAVVIS.  SAVVIS  may,  but  shall  not be  obligated  to,  use
                  facilities   of  SAVVIS  other  than  the   Acquired   Network
                  Facilities  to  provide  all  or  any  part  of  any  Network.
                  Beginning on the first  anniversary  of the Effective Date and
                  thereafter,  each  Network  shall  be  operated,  managed  and
                  maintained  by SAVVIS  according  to the  Quality  of  Service
                  Standards  set forth in Schedule 2.2 hereof,  and SAVVIS shall
                  be responsible  for monitoring the performance of the Networks
                  with  respect to the  Quality of Service  Standards  and shall
                  provide Customer with monthly reports of such performance.  If
                  the Quality of Service Standards are not met with respect to a
                  particular  Installation Site in any month,  Customer shall be
                  entitled to receive,  upon written  request by Customer within
                  30 days of its  receipt  of the  performance  report  for such
                  Installation  Site for such month,  a credit in the amount set
                  forth on Schedule  2.2  attached  hereto (or, in the case of a
                  Distributor  Country,  as set  forth  on  Schedule  2.2 to the
                  Network Services  Agreement),  which amount shall be deemed to
                  be one month's charges  applicable to such  Installation  Site
                  under this  Agreement  with  respect to such month;  provided,
                  however, that Customer shall not be entitled to such credit to
                  the extent  that the  failure  to meet the  Quality of Service
                  Standards with respect to such Installation Site is due to (i)
                  an act or  omission  of  Customer  or a vendor or  customer of
                  Customer or (ii)  equipment  or software  used by Customer and
                  not  provided  by  SAVVIS.  Not more  than one  credit  of one
                  month's  charges shall be given for a particular  Installation
                  Site for a particular  month. The Quality of Service Standards
                  shall not apply to the provision of Local Access Facilities in
                  countries  in which the  products  and  services of Bridge and
                  Bridge   Subsidiaries   are   provided   through   third-party
                  distributors.  For all purposes of this  Agreement,  including
                  without limitation the determination of an Event of Default by
                  SAVVIS,  the  Quality of  Service  Standards  applicable  to a
                  particular  Installation  Site in any month shall be deemed to
                  have been met unless  Customer,  within 30 days of its receipt
                  of the performance  report for such Installation Site for such
                  month,  requests  in writing a credit as set forth  above with
                  respect to such Installation Site for such month.

         2.3.     [Intentionally omitted.]

         2.4.     In providing  Additional Network Facilities,  SAVVIS agrees to
                  use its best  efforts  to  expedite  the  provisioning  of the
                  circuits  for  such  Additional  Network  Facilities  in those
                  instances in which SAVVIS is responsible for provisioning such
                  circuits,  and to use its best efforts to avoid single  points
                  of  failure  in the  engineering  design  of  such  Additional
                  Network  Facilities,  consistent  with the level of redundancy
                  specified in the applicable Addendum.

2.5.              Throughout  the term of this  Agreement,  SAVVIS shall use its
                  reasonable  best  efforts to continue to meet the  requests of
                  Customer to enhance the total capacity,

                                       5
<PAGE>

                  geographic  extension and performance quality of the Networks,
                  and to maintain its research and development effort at a level
                  appropriate  to sustain  the ability of Customer to compete on
                  the basis of the quality of the Networks.

3.       RATES AND CHARGES

         3.1.     Customer  shall pay SAVVIS for the Networks using the Acquired
                  Network Facilities and Additional Network Facilities according
                  to the rates and  charges  set  forth in  Schedule  3.1 of the
                  Network Services Agreement.

         3.2.     The parties  recognize that certain  savings might be obtained
                  by consolidating the multiple Local Access Facilities that are
                  provided at such building  locations on the Effective Date. In
                  the event that SAVVIS  consolidates  the multiple Local Access
                  Facilities  at one or  more  of such  building  locations  and
                  obtains  cost  savings as a result  thereof,  the parties will
                  mutually agree within 30 days following such  consolidation on
                  the manner in which such savings shall be shared as follows:

                  (a)      between  SAVVIS and  Customer,  if only Customer uses
                           those consolidated Local Access Facilities; or

                  (b)      between   SAVVIS,   Customer  and  the  Affiliate  of
                           [Telerate  Parent]/[Bridge Parent] that is a party to
                           the  Local   [Telerate]/[Bridge]   Network   Services
                           Agreement,  if both  Customer and such  Affiliate use
                           those consolidated Local Access Facilities.

         3.3.     For  any  Installation  Site  to  which  SAVVIS  is  providing
                  services    both   under   this    Agreement   and   a   Local
                  [Telerate]/[Bridge]  Network Services Agreement, the rates and
                  charges  applicable  to  such  Installation  Site  under  this
                  Agreement  shall be  one-half  of the rates and  charges  that
                  would otherwise be applicable to such  Installation Site under
                  this Agreement.

4.       PROVISION OF TAIL CIRCUITS

         4.1.     SAVVIS  shall use its  reasonable  efforts  to  provide a Tail
                  Circuit to Customer  by  contracting  with the Local  Exchange
                  Carrier  for access to the Tail  Circuit  and causing the Tail
                  Circuit to be operated,  managed,  and maintained as necessary
                  to  provide  access  thereto  to  Customer.  SAVVIS  does  not
                  guarantee  or warrant the  performance  of the Tail Circuit or
                  the   performance  by  the  Local  Exchange   Carrier  of  its
                  obligations  under any contract  between  SAVVIS and the Local
                  Exchange   Carrier,   applicable  laws  and  regulations,   or
                  standards of the industry.

         4.2.     Customer  shall not use the Tail Circuit in any way that might
                  cause SAVVIS to violate the terms and  conditions  under which
                  access to the Tail  Circuit is provided by the Local  Exchange
                  Carrier,  whether such terms and  conditions  be  contractual,
                  regulatory, or other.

                                       6
<PAGE>

         4.3.     Customer shall be responsible for only that portion of SAVVIS'
                  costs  attributable to Customer's own access to and use of the
                  Tail Circuit.  In the event that SAVVIS provides access to any
                  third  party or parties,  Customer  and SAVVIS will follow the
                  procedure set forth in Section 1.2 above in order to establish
                  a mutually  agreed upon method or formula for  determining the
                  amount to be charged  to  Customer,  generally  based on a pro
                  rata allocation of SAVVIS' total costs among all its customers
                  and other relevant  considerations  and/or fair and reasonable
                  adjustments in light of the circumstances at that time.

5.       INVOICES

         5.1.     The amounts due to SAVVIS from Customer for the  installation,
                  operation, management and maintenance of the Networks shall be
                  billed  monthly  in  advance.  All items on  invoices  not the
                  subject of a bona fide dispute shall be payable by Customer in
                  legal currency of [jurisdiction]  within 30 days from the date
                  of receipt of the  invoice.  All  amounts  not in dispute  are
                  subject to interest  charges of 1-1/2 percent that will accrue
                  daily on all  amounts  not paid  within 30 days of the date of
                  receipt of the invoice.

         5.2.     At any time and from time to time,  Customer  may,  by written
                  notice to SAVVIS,  have one or more Installation Sites removed
                  from  the  Networks.  Each  monthly  invoice  from  SAVVIS  to
                  Customer  shall  reflect a reduction in the amount  charged to
                  Customer for the Networks  resulting  from any such removal of
                  Installation  Sites.  In the  case  of any  Installation  Site
                  removed from the Acquired Network  Facilities,  such reduction
                  shall be the sum of:

                  (a)      the  actual  cost  of  the  Local  Access  Facilities
                           connecting  the Acquired  Network  Facilities to such
                           Installation  Site,  effective  as of  such  time  as
                           SAVVIS is no longer required to pay such costs, and

                  (b)      the amounts set forth on Schedule  5.2 of the Network
                           Services  Agreement,  which  are  deemed  to  be  one
                           month's charges  applicable to such Installation Site
                           under  this  Agreement  with  respect  to such  month
                           during the first  Agreement  Year,  according  to the
                           geographic  location  and  connection  speed  at such
                           Installation Site,  effective as of such time as such
                           Installation Site is disconnected from the Networks.

         5.3.     Customer shall pay any sales,  use,  federal excise,  utility,
                  gross receipts,  state and local  surcharges,  value added and
                  similar  taxes,  charges or levies  lawfully  levied by a duly
                  constituted taxing authority against or upon the Networks.  In
                  the   alternative,   Customer  shall  provide  SAVVIS  with  a
                  certificate evidencing Customer's exemption from payment of or
                  liability for such taxes. All other taxes,  charges or levies,
                  including  any ad valorem,  income,  franchise,  privilege  or
                  occupation taxes of SAVVIS shall be paid by SAVVIS.

         5.4.     Bona fide disputes  concerning  invoices  shall be referred to
                  the parties' respective  representatives who are authorized to
                  resolve such matters. Any amount to which Customer is entitled
                  as a result of the  resolution  of a billing  dispute shall be
                  credited promptly to Customer's  account.  Any amount to which
                  SAVVIS is entitled as a result of the  resolution of a billing
                  dispute shall be paid promptly to SAVVIS.

         5.5.     Against  the amounts  owed by  Customer  to SAVVIS  under this
                  Agreement, Customer shall have the right to offset any amounts
                  owed by SAVVIS to Customer under this Agreement, or otherwise,
                  including without limitation any amounts paid by Bridge Parent
                  on behalf  of  SAVVIS  under  guarantees  by Bridge  Parent of
                  obligations of SAVVIS.

6.       TERM AND EXTENSIONS

         6.1.     This Agreement  shall commence on the Effective Date and shall
                  continue in full force and effect for the Initial  Term unless
                  terminated  or  extended  in  accordance  with the  provisions
                  hereof.

         6.2.     The term of this Agreement may be extended by Customer for one
                  additional  five-year  period by giving SAVVIS  written notice
                  not less than one year before the scheduled  expiration of the
                  Initial Term.

         6.3.     Upon the  termination of this Agreement in accordance with its
                  scheduled  expiration  or by  Customer  pursuant to Section 7,
                  SAVVIS will  continue to provide  the  Networks in  accordance
                  with the terms and  conditions  herein  (excluding the Minimum
                  Annual  Commitment) for a period of up to five years after the
                  effective  date  of  termination  (the  "TRANSITION  PERIOD").
                  During the  Transition  Period,  Customer shall pay SAVVIS for
                  the  use of  the  Networks  at  the  rates  in  effect  at the
                  effective date of termination.  If Customer has not completely
                  transitioned from its use of the Networks after the Transition
                  Period,  SAVVIS  will  provide the  Networks  at SAVVIS'  then
                  current list rates.  SAVVIS and its successor  will  cooperate
                  with  Customer  until  Customer  has  completely  migrated  to
                  another provider.

         6.4.     The above  provisions of this Section 6  notwithstanding,  the
                  term of this  Agreement,  including  the Initial  Term and any
                  extension  provided  under  Section  6.2,  and the  Transition
                  Period  shall not  extend  beyond  the term or the  transition
                  period of the Network Services Agreement.

7.       TERMINATION BY CUSTOMER

         7.1.     An "EVENT OF DEFAULT BY SAVVIS" shall be deemed to occur if:

                  (a)      SAVVIS has failed to a material  degree to perform or
                           comply   with   or   has    violated   any   material
                           representation,    warranty,   term,   condition  or

                                       8
<PAGE>

                           obligation of SAVVIS under this Agreement, and SAVVIS
                           has failed to cure such failure or  violation  within
                           60 days after receiving notice thereof from Customer;
                           or

                  (b)      SAVVIS   becomes  the  subject  of  a  voluntary   or
                           involuntary bankruptcy, insolvency, reorganization or
                           liquidation  proceeding,  makes an assignment for the
                           benefit  of  creditors,  or  admits  in  writing  its
                           inability to pay debts when due; or

                  (c)      an Event of Default by SAVVIS  occurs under the Local
                           [Telerate]/[Bridge]  Network  Services  Agreement  or
                           SAVVIS Communications defaults under the terms of the
                           Network Services Agreement.

         7.2.     Customer  shall have the right to  terminate  this  Agreement,
                  with no liability  to SAVVIS other than for charges  (less any
                  applicable  credits) for the Networks  provided  prior to such
                  termination, if:

                  (a)      Customer  provides  written notice to SAVVIS,  at any
                           time  after the ninth  anniversary  of the  Effective
                           Date,  of  Customer's   intent  to  terminate,   such
                           termination  to be  effective  not less than one year
                           following the date of such notice; or

                  (b)      Customer  provides  10  days  written  notice  of its
                           intent to  terminate  in the  event  that an Event of
                           Default by SAVVIS occurs.

         7.3.     For  purposes  of Section  7.1(a),  if the  Quality of Service
                  Standards   are  not  met  with   respect   to  a   particular
                  Installation Site in any month, SAVVIS shall be deemed to have
                  cured such  failure  within 60 days if the  Quality of Service
                  Standards  are met with respect to such  Installation  Site in
                  the following  month.  The parties  acknowledge and agree that
                  the failure of the Quality of Service Standards to be met with
                  respect  to one or  more  Installation  Sites  in one or  more
                  months may, but does not necessarily,  constitute a failure by
                  SAVVIS to a material  degree to  perform  or comply  with or a
                  violation to a material degree of any material representation,
                  warranty,  term,  condition or obligation of SAVVIS under this
                  Agreement.

         7.4.     As  provided  in  Section   2.2,  for  all  purposes  of  this
                  Agreement,  including without  limitation the determination of
                  an Event of Default by SAVVIS under this Section,  the Quality
                  of Service Standards  applicable to a particular  Installation
                  Site in any month  shall be  deemed  to have  been met  unless
                  Customer,  within 30 days of its  receipt  of the  performance
                  report for such Installation Site for such month,  requests in
                  writing a credit as set forth in Section  2.2 with  respect to
                  such Installation Site for such month.

                           the subject of a bona fide dispute  within 60 days of
                           the date on which such  payment is due and SAVVIS has
                           provided   Customer  with  written  notice   thereof,
                           provided that  Customer  shall have a further 30 days
                           from the time it receives  such notice from SAVVIS of
                           nonpayment to cure any such default;

                  (b)      SAVVIS  provides 10 days written notice of its intent
                           to terminate in the event that Customer has failed to
                           perform or comply with or has  violated  any material
                           representation,    warranty,   term,   condition   or
                           obligation  of  Customer  under this  Agreement,  and
                           Customer has failed to cure such failure or violation
                           within 60 days after  receiving  notice  thereof from

                  (c)      Customer  becomes  the  subject  of  a  voluntary  or
                           involuntary bankruptcy, insolvency, reorganization or
                           liquidation  proceeding,  makes an assignment for the
                           benefit  of  creditors,  or  admits  in  writing  its
                           inability to pay debts when due; or

                  (d)      SAVVIS  becomes   entitled  to  terminate  the  Local
                           [Telerate]/[Bridge]  Network  Services  Agreement  or
                           SAVVIS  Communications  becomes entitled to terminate

         8.2.     Notwithstanding the provisions of Section 8.1(b) above, SAVVIS
                  shall not have the right to  terminate  this  Agreement  under
                  Section  8.1(b) solely for a failure by Customer to perform or
                  comply with, a violation  by Customer of, the  obligations  of
                  Customer under Section 15 (Confidentiality) of this Agreement,
                  without prejudice,  however, to such rights as SAVVIS may have
                  pursuant to such  Section  and to such rights and  remedies to
                  which  SAVVIS may be  entitled,  at law or in  equity,  as the
                  result of an actual or  threatened  breach by Customer of such
                  Section.

9.       ACCEPTANCE OF ADDITIONAL NETWORK FACILITIES

         9.1.     Upon the installation of Additional  Network Facilities at any
                  Installation  Site, SAVVIS shall conduct  appropriate tests to
                  establish that such Additional  Network  Facilities perform in
                  accordance  with  mutually  agreed  upon  acceptance  criteria
                  ("ACCEPTANCE  CRITERIA") set forth in the applicable  Addendum
                  entered  into  pursuant  to Section  2.4,  and shall  promptly
                  inform  Customer of such test  results.  If test  results show
                  that the  Additional  Network  Facilities  are  performing  in
                  accordance  with the  Acceptance  Criteria,  Customer shall be
                  deemed to accept  the  Additional  Network  Facilities  at the
                  Installation Site immediately.

         9.2.     If SAVVIS' tests  establish  that newly  installed  Additional
                  Network  Facilities at the Installation Site do not perform in
                  accordance with the mutually agreed upon Acceptance  Criteria,
                  then SAVVIS shall  immediately  and diligently  exert its best
                  efforts to bring the  Additional  Network  Facilities  at such
                  Installation  Site  into  compliance.  SAVVIS  shall  not bill
                  Customer  for  the  Additional   Network  Facilities  at  such
                  Installation  Site  until  the  test  results  show  that  the
                  Additional  Network  Facilities  are  performing in accordance
                  with the Acceptance Criteria.

         9.3.     Upon repair or restoration of any part of the Networks, SAVVIS
                  shall conduct appropriate tests to establish that the Networks
                  perform in  accordance  with mutually  agreed upon  Acceptance
                  Criteria  and  shall  promptly  inform  Customer  of such test
                  results.

10.      RIGHTS AND OBLIGATIONS OF CUSTOMER

         10.1.    SITE PREPARATION.  For the installation of Additional  Network
                  Facilities,  Customer shall,  at its own expense,  provide all
                  necessary preparations of each Installation Site in accordance
                  with  the  requirements  to be  mutually  agreed  upon  by the
                  parties and set forth in an Addendum hereto,  including inside
                  wiring,  demarcation  extension  and rack  mount  accessories.
                  Customer  shall  ensure that  Customer-provided  equipment  is
                  on-site  by the  scheduled  installation  date.  If  SAVVIS is
                  required to reschedule the  installation of  Customer-provided
                  equipment   because  it  is  not  on-site  by  the   scheduled
                  installation  date,  Customer  shall pay SAVVIS to  redispatch
                  installation personnel.

         10.2.    PROPER USE OF NETWORKS.

                  10.2.1.  Customer  shall use any equipment  provided by SAVVIS
                           in connection  with the Networks in  accordance  with
                           its  documentation,   which  documentation  shall  be
                           provided by SAVVIS at no  additional  charge.  Unless
                           otherwise  provided  herein,  upon the termination of
                           this Agreement Customer shall surrender to SAVVIS the
                           equipment  provided by SAVVIS, in good working order,
                           ordinary wear and tear excepted.

                  10.2.2.  Customer  shall be liable for damages to the Networks
                           caused by the negligence or willful acts or omissions
                           of   Customer's   officers,   employees,   agents  or
                           contractors,  for loss through  theft or vandalism of
                           the  Networks  at  the  Installation  Site,  and  for
                           damages  to  the  Networks   caused  by  the  use  of
                           equipment or supplies  not provided  hereunder or not
                           otherwise authorized by SAVVIS.

                  10.2.3.  Customer  shall  neither  permit nor assist others to
                           use the Networks for any purpose  other than that for
                           which  they  are  intended,  nor fail to  maintain  a
                           suitable  environment  specified  by  SAVVIS  in  the
                           applicable  schedule,  nor alter, tamper with, adjust
                           or  repair  the   Networks.   Any  such   alteration,
                           tampering,  adjustment  or repair by  Customer  shall
                           relieve

                           SAVVIS from any  liability  or  obligation  hereunder
                           (including  any  warranty  or  indemnity  obligation)
                           relating to the affected Network,  and Customer shall
                           be liable to SAVVIS for any  documented  direct costs
                           incurred by SAVVIS as a result of such actions.

         10.3.    ABUSE OR FRAUDULENT  USE OF NETWORKS.  Customer  shall neither
                  permit  nor  assist  others to abuse or  fraudulently  use the
                  Networks,  or to use  the  Networks  for any  unauthorized  or
                  illegal purposes, including:

                  (a)      obtaining  or  attempting  to obtain  service  by any
                           fraudulent means or device to avoid payment; or

                  (b)      accessing,  altering or destroying any information of
                           another party by any fraudulent  means or device,  or
                           attempting to do so; or

                  (c)      using the Networks so as to interfere with the use of
                           the  SAVVIS  network  by other  SAVVIS  customers  or
                           authorized users or in violation of law or in support
                           of any unlawful act; or

                  (d)      using the  Networks for voice  communications  over a
                           private  network in  jurisdictions  where such use is
                           not allowed.

                  Notwithstanding  the  provisions of Section 8, upon the breach
                  of this Section 10.3 by Customer,  SAVVIS shall have the right
                  to terminate this Agreement immediately upon written notice to
                  Customer.

         10.4.    COVENANT NOT TO COMPETE.

                  10.4.1.  As  an  inducement  to  SAVVIS  to  enter  into  this
                           Agreement,  which Customer acknowledges is of benefit
                           to it,  and in  consideration  of  the  promises  and
                           representations   of  SAVVIS  under  this  Agreement,
                           Customer covenants and agrees that during the term of
                           this  Agreement  and  for  a  period  of  five  years
                           thereafter,   neither   Customer   nor   any  of  its
                           successors or assigns will,  directly or  indirectly,
                           engage in, or have any interest in any other  person,
                           firm,  corporation  or other  entity  engaged in, any
                           business activities anywhere in the world competitive
                           with  or  similar  or  related  to  the   packet-data
                           transport  network services  provided by SAVVIS under
                           this Agreement;  provided, however, that (i) Customer
                           shall be free to  continue to use the Call Assets and
                           the satellite  networks  currently  used by Customer,
                           until such Call  Assets or  satellite  networks  have
                           been  acquired by SAVVIS,  SAVVIS  Communications  or
                           Affiliates   of  SAVVIS   Communications,   and  (ii)
                           Customer shall be free to make passive investments in
                           securities of companies that provide network services
                           in competition  with SAVVIS which, in the case of any
                           such  security,  does not  constitute  more  than ten
                           percent (10%) of the total outstanding amount of such
                           security.

                  10.4.2.  If any court or  tribunal of  competent  jurisdiction
                           shall refuse to enforce one or more of the  covenants
                           in  this   Section   10.4   because  the  time  limit
                           applicable  thereto  is  deemed  unreasonable,  it is
                           expressly understood and agreed that such covenant or
                           covenants  shall not be void but that for the purpose
                           of such  proceedings  such time  limitation  shall be
                           deemed  to be  reduced  to the  extent  necessary  to
                           permit the enforcement of such covenant or covenants.

                  10.4.3.  If any court or  tribunal of  competent  jurisdiction
                           shall  refuse to enforce any or all of the  covenants
                           in this Section 10.4 because,  taken  together,  they
                           are more  extensive  (whether as to geographic  area,
                           scope of business or otherwise)  than is deemed to be
                           reasonable,  it is  expressly  understood  and agreed
                           between  the  parties  hereto  that such  covenant or
                           covenants  shall not be void but that for the purpose
                           of  such  proceedings  the   restrictions   contained
                           therein  (whether  as to  geographic  area,  scope of
                           business or otherwise)  shall be deemed to be reduced
                           to the extent  necessary to permit the enforcement of
                           such covenant or covenants.

                  10.4.4.  Customer  specifically  acknowledges  and agrees that
                           the foregoing  covenants are commercially  reasonable
                           and reasonably  necessary to protect the interests of
                           SAVVIS hereunder.  Customer hereby  acknowledges that
                           SAVVIS and its  successors  and  assigns  will suffer
                           irreparable  and  continuing  harm to the extent that
                           any of the  foregoing  covenants is breached and that
                           legal  remedies  would be  inadequate in the event of
                           any such breach.

11.      RIGHTS AND OBLIGATIONS OF SAVVIS

         11.1.    PROVISION OF THE NETWORKS.  SAVVIS shall operate, maintain and
                  manage  the  Networks  at the  Installation  Sites  using  the
                  Acquired Network  Facilities in accordance with the Quality of
                  Service Standards and other terms of this Agreement, including
                  all Addenda hereto.

         11.2.    REPRESENTATIONS AND WARRANTIES.

                  11.2.1.  [Intentionally omitted.]

                  11.2.2.  SAVVIS hereby  represents and warrants that the terms
                           hereof do not conflict in any respect whatsoever with
                           any   SAVVIS   tariff  on  file   with  the   Federal
                           Communications  Commission or other  regulatory body.
                           If, during the term of this  Agreement,  SAVVIS shall
                           file  a  contract   specific  tariff   governing  the
                           Networks or any portion  thereof,  such tariff filing
                           shall be consistent in all respects with the terms of
                           this  Agreement,  and SAVVIS  shall give  Customer 10
                           days advance  written  notice of making such a tariff
                           filing  and of filing  any  subsequent  modifications
                           thereto.

<PAGE>

                  11.2.3.  THE  FOREGOING  WARRANTIES  ARE IN LIEU OF ALL  OTHER
                           WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED
                           WARRANTIES  OF  MERCHANTABILITY  AND  FITNESS  FOR  A
                           PARTICULAR PURPOSE.

         11.3.    SAVVIS acknowledges that the occurrence of Event of Default by
                  SAVVIS,  arising  from either (i) a failure of the Networks to
                  meet  Quality  of  Service  Standards  or (ii) a total loss to
                  Customer of the use of the Networks,  could cause  irreparable
                  harm to  Customer,  the  amount of which may be  difficult  to
                  determine,  thus  potentially  making  any remedy at law or in
                  damages inadequate.  SAVVIS,  therefore,  agrees that Customer
                  shall  have  the  right to  apply  to any  court of  competent
                  jurisdiction  for injunctive  relief upon the occurrence of an
                  Event of  Default  by  SAVVIS  or the  occurrence  of an event
                  which, with the passage of time or the giving of notice, could
                  become  an  Event  of  Default  by  SAVVIS  and for any  other
                  appropriate  relief.  This right  shall be in  addition to any
                  other remedy  available  to Customer in law or equity.  SAVVIS
                  further  agrees  that,  upon  the  occurrence  of an  Event of
                  Default by SAVVIS, SAVVIS shall pay to Customer, as liquidated
                  damages and not as a penalty, an amount equal to the lesser of
                  (a) the  aggregate  amounts  paid by Customer to SAVVIS  under
                  this Agreement  during the six months  preceding such Event of
                  Default by SAVVIS or (b) $50,000,000;  provided, however, that
                  Customer  may recover  liquidated  damages  under this Section
                  only for an Event of Default by SAVVIS  that  occurs (i) prior
                  to any Event of  Default  by  SAVVIS  for  which  Customer  or
                  [Bridge  Parent]/[Telerate  Parent] or any customer of [Bridge
                  Parent]/[Telerate Parent] has claimed liquidated damages under
                  this  Section  or under a Network  Services  Agreement  or any
                  Local [Telerate]/[Bridge]  Network Services Agreement, or (ii)
                  more than 36 months following the most recent Event of Default
                  by SAVVIS  for which  Customer  or  [Bridge  Parent]/[Telerate
                  Parent] or any customer of [Bridge  Parent]/[Telerate  Parent]
                  has claimed  liquidated  damages under this Section or under a
                  Network  Services  Agreement or any Local  [Telerate]/[Bridge]
                  Network Services Agreement.

12.      LIMITATIONS OF LIABILITY

         12.1.    Subject to Section 11.4,  neither party shall be liable to the
                  other  for  indirect,  incidental,  consequential,  exemplary,
                  reliance  or  special  damages,  including  damages  for  lost
                  profits, regardless of the form of action whether in contract,
                  indemnity,  warranty,  strict  liability  or  tort,  including
                  negligence  of any kind with  respect to the Networks or other
                  conduct under this Agreement.

         12.2.    Nothing  contained in this Section shall limit either  party's
                  liability  to  the  other  for  (a)  willful  or   intentional
                  misconduct, including fraud, or (b) injury or death, or damage
                  to  tangible  real  or  tangible   personal  property  or  the
                  environment,  when proximately caused by SAVVIS' or Customer's
                  negligence or that of their respective agents,  subcontractors
                  or  employees.  Nothing  contained in this

<PAGE>


                  Section    shall   limit   SAVVIS'    intellectual    property
                  indemnification  obligations  under Section 16.1 or Customer's
                  indemnification  obligations  with  respect  to  a  breach  of
                  Section 10.3.

13.      EQUIPMENT AND SOFTWARE NOT PROVIDED BY SAVVIS

         13.1.    SAVVIS  shall  not  be  responsible   for  the   installation,
                  operation or maintenance of equipment or software not provided
                  by it under this  Agreement,  nor shall SAVVIS be  responsible
                  for the  transmission or reception of information by equipment
                  or software  not  provided by SAVVIS  hereunder.  In the event
                  that  Customer  uses  equipment  or software  not  provided by
                  SAVVIS  hereunder in a manner that impairs  Customer's  use of
                  the Networks,  Customer  shall not be excused from payment for
                  such use and SAVVIS shall not be  responsible  for any failure
                  of the  Networks  to meet the  Quality  of  Service  Standards
                  resulting  from  the  use of such  equipment  or  software  by
                  Customer.  Upon  notice  from  SAVVIS  that the  equipment  or
                  software  not  provided  by SAVVIS  under  this  Agreement  is
                  causing or is likely to cause hazard,  interference or service
                  obstruction,  Customer shall  eliminate the likelihood of such
                  hazard, interference or service obstruction.

         13.2.    Notwithstanding the foregoing,  SAVVIS shall, at no additional
                  charge, provide all interface  specifications for the Networks
                  reasonably  requested  by  Customer.  SAVVIS  shall,  upon the
                  receipt of appropriate  specifications  from Customer,  inform
                  Customer  of  the  compatibility  with  the  Networks  of  any
                  equipment  or  software  that  Customer  proposes  to  use  in
                  connection therewith,  the effects, if any, of the use of such
                  equipment    or   software   on   the    quality,    operating
                  characteristics  and  efficiency  of  the  Networks,  and  the
                  effects,   if  any,   of  the   Networks   on  the   operating
                  characteristics  and  efficiency  of  any  such  equipment  or
                  software.

14.      PROPRIETARY RIGHTS; LICENSE

         14.1.    SAVVIS   hereby  grants  to  Customer  a   non-exclusive   and
                  non-transferable  license to use all  programming and software
                  necessary  for Customer to use the  Networks.  Such license is
                  granted for the term of this Agreement for the sole purpose of
                  enabling Customer to use the Networks.

         14.2.    All title and property rights (including intellectual property
                  rights) to the Networks (including associated  programming and
                  software) are and shall remain with SAVVIS or the  third-party
                  providers  thereof to SAVVIS.  Customer  shall not  (except as
                  permitted by applicable law) attempt to examine,  copy, alter,
                  reverse  engineer,  decompile,  disassemble,  tamper  with  or
                  otherwise misuse the Networks, programming and software.

15.      CONFIDENTIALITY

         15.1.    During  the term of this  Agreement  and for a period  of five
                  years  from  the  date  of  its   expiration  or   termination
                  (including  all  extensions  thereof),  each  party  agrees to
                  maintain in strict  confidence all  Confidential  Information.
                  Neither  party shall,  without  prior  written  consent of the
                  other party,  use the other party's  Confidential  Information
                  for any purpose other than for the  performance  of its duties
                  and  obligations,  and the exercise of its rights,  under this
                  Agreement.   Each  party  shall  use,   and  shall  cause  all
                  authorized   recipients  of  the  other  party's  Confidential
                  Information  to use,  the same  degree of care to protect  the
                  other party's  Confidential  Information as it uses to protect
                  its own  Confidential  Information,  but in any event not less
                  than a reasonable degree of care.

         15.2.    Notwithstanding  Section  15.1,  either party may disclose the
                  Confidential  Information  of the  other  party  to:  (a)  its
                  employees  and the  employees,  directors  and officers of its
                  Affiliates  as  necessary  to implement  this  Agreement;  (b)
                  employees,  agents or  representatives  of the other party; or
                  (c) other persons (including counsel, consultants,  lessors or
                  managers of  facilities  or  equipment  used by such party) in
                  need of access to such  information for purposes  specifically
                  related  to  either   party's   responsibilities   under  this
                  Agreement,   provided  that  any  disclosure  of  Confidential
                  Information  under  clause  (c) shall be made only upon  prior
                  written  approval  of  the  other  party  and  subject  to the
                  appropriate  assurances that the recipient of such information
                  shall hold it in strict confidence.

         15.3.    Upon the  request of the party  having  proprietary  rights to
                  Confidential  Information,  the  party in  possession  of such
                  information  shall  promptly  return it (including any copies,
                  extracts and  summaries  thereof,  in whatever form and medium
                  recorded) to the  requesting  party or, with the other party's
                  written  consent,  shall  promptly  destroy it and provide the
                  other party with written certification of such destruction.

         15.4.    Either party may request in writing that the other party waive
                  all or any portion of the requesting party's  responsibilities
                  relative to the other party's Confidential  Information.  Such
                  waiver request shall identify the affected information and the
                  nature of the proposed  waiver.  The  recipient of the request
                  shall respond within a reasonable  time and, if it determines,
                  in its sole discretion, to grant the requested waiver, it will
                  do so in writing over the signature of an employee  authorized
                  to grant such request.

         15.5.    Customer  and  SAVVIS   acknowledge  that  any  disclosure  or
                  misappropriation  of Confidential  Information in violation of
                  this  Agreement  could cause  irreparable  harm, the amount of
                  which may be difficult to determine,  thus potentially  making
                  any  remedy  at  law or in  damages  inadequate.  Each  party,
                  therefore, agrees that the other party shall have the right to
                  apply to any  court  of  competent  jurisdiction

                                       16
<PAGE>

                  for an order  restraining  any breach or threatened  breach of
                  this Section and for any other appropriate  relief. This right
                  shall be in addition to any other  remedy  available in law or
                  equity.

         15.6.    A party requested or ordered by a court or other  governmental
                  authority  of  competent   jurisdiction  to  disclose  another
                  party's Confidential  Information shall notify the other party
                  in  advance  of any such  disclosure  and,  absent  the  other
                  party's  consent to such  disclosure,  use its best efforts to
                  resist,  and to assist  the  other  party in  resisting,  such
                  disclosure.  A party providing  another  party's  Confidential
                  Information to a court or other  governmental  authority shall
                  use  its  best  efforts  to  obtain  a  protective   order  or
                  comparable  assurance  that the  Confidential  Information  so
                  provided will be held in confidence and not further  disclosed
                  to any other person, absent the owner's prior consent.

         15.7.    The  provisions  of  Section  15.1  above  shall  not apply to
                  reasonably  necessary  disclosures  in or in  connection  with
                  filings  under any  securities  laws,  regulatory  filings  or
                  proceedings,  financial  disclosures  which in the good  faith
                  judgment  of  the  disclosing   party  are  required  by  law,
                  disclosures   required  by  court  or  tribunal  or  competent
                  jurisdiction,  or disclosures that may be reasonably necessary
                  in connection  with the sale of securities or the  performance
                  or  enforcement  of this  Agreement or any of the  obligations
                  hereof;  provided,  however, that if the receiving party would
                  otherwise  be required  to refer to or describe  any aspect of
                  this  Agreement  in any of the  preceding  circumstances,  the
                  receiving party shall use its reasonable  efforts to take such
                  steps as are available  under such  circumstances  (such as by
                  providing a summary or  synopsis) to avoid  disclosure  of the
                  financial    terms   and   conditions   of   this   Agreement.
                  Notwithstanding  any  provisions  of  this  Agreement  to  the
                  contrary,  either party may disclose the terms and  conditions
                  of this  Agreement  in the  course of a due  diligence  review
                  performed in connection  with  prospective  debt  financing or
                  equity  investment by, or a sale to, a third party, so long as
                  the persons  conducting such due diligence  review have agreed
                  to maintain the  confidentiality of such disclosure and not to
                  use such  disclosure  for any purpose other such due diligence
                  review.

16.      INDEMNIFICATIONS

         16.1.    SAVVIS shall defend,  settle,  or otherwise  manage at its own
                  cost and expense any claim or action  against  Customer or any
                  of its directors, officers, employees or assigns for actual or
                  alleged infringement by the Networks of any patent, copyright,
                  trademark,  trade secret or similar  proprietary  right of any
                  third party,  except to the extent that such actual or alleged
                  infringement   arises   from  (i)  such   actual  or   alleged
                  infringement  by  the  Acquired  Network   Facilities  on  the
                  Effective  Date or (ii) an act or  omission  of  Customer or a
                  vendor or customer of Customer or (iii)  equipment or software
                  used by Customer  and not provided by SAVVIS.  Customer  shall
                  notify  SAVVIS  promptly  in writing of any such claim or suit
                  and  shall  cooperate  with  SAVVIS  in a  reasonable  way  to
                  facilitate the

                                       17
<PAGE>


                  settlement  or  defense  thereof.  SAVVIS  further  agrees  to
                  indemnify and hold Customer  harmless from and against any and
                  all liabilities and damages (whether incurred as the result of
                  a judicial decree or a settlement), and the costs and expenses
                  associated  with any claim or action of the type identified in
                  this Section (including reasonable attorneys' fees).

         16.2.    If,  as a  consequence  of a  claim  or  action  of  the  kind
                  described in Section 16.1, SAVVIS' or Customer's use of all or
                  part of any Network is enjoined,  SAVVIS shall,  at its option
                  and  expense,  either:  (a) procure for  Customer the right to
                  continue using the affected  Network;  (b) modify such Network
                  so  that   they  are   non-infringing,   provided   that  such
                  modification  does not affect the  intended use of the Network
                  as contemplated  hereunder. If SAVVIS does not take any of the
                  actions  described  in clauses (a) or (b),  then  Customer may
                  terminate  the affected  portion of such  Network,  and SAVVIS
                  shall refund to Customer any prepaid charges therefor.

         16.3.    Subject to Section 12,  Customer  will defend,  indemnify  and
                  hold  harmless  SAVVIS  or  any of  its  directors,  officers,
                  employees  or assigns  from and against  all loss,  liability,
                  damage and  expense,  including  reasonable  attorneys'  fees,
                  caused by:

                  (a)      claims for  libel,  slander,  invasion  of privacy or
                           infringement   of  copyright,   and  invasion  and/or
                           alteration  of private  records or data  arising from
                           any  information,  data or messages  transmitted over
                           the Networks by Customer;

                  (b)      claims for  infringement  of patents arising from the
                           use by Customer of equipment and software,  apparatus
                           and systems not provided hereunder in connection with
                           the Networks; and

                  (c)      the violation of any representations,  warranties and
                           covenants made by Customer in this Agreement.

         16.4.    Subject to Section 12, SAVVIS will defend,  indemnify and hold
                  harmless Customer or any of its directors, officers, employees
                  or assigns  from and against all loss,  liability,  damage and
                  expense, including reasonable attorneys' fees, caused by:

                  (a)      claims for  infringement  of patents arising from the
                           use by SAVVIS of equipment  and  software,  apparatus
                           and  systems  not  provided  by SAVVIS  hereunder  in
                           connection with the Networks (other than any Acquired
                           Network Facilities); and

                  (b)      the violation of any representations,  warranties and
                           covenants made by SAVVIS in this Agreement.

17.      DISPUTES

         17.1.    Except  as   expressly   provided  in  Schedule  4.1  of  this
                  Agreement, the resolution of any and all disputes arising from
                  or  in  connection  with  this  Agreement,  whether  based  on
                  contract, tort, statute or otherwise,  including disputes over
                  arbitrability  and disputes in connection with claims by third
                  persons  ("DISPUTES")  shall be  exclusively  governed  by and
                  settled in accordance  with the provisions of this Section 17.
                  The  foregoing   shall  not  preclude   recourse  to  judicial
                  proceedings to obtain injunctive, emergency or other equitable
                  relief to enforce the provisions of this Agreement,  including
                  specific  performance,  and  to  decide  such  issues  as  are
                  required to be resolved in  determining  whether to grant such
                  relief. Resolution of Disputes with respect to claims by third
                  persons shall be deferred until any judicial  proceedings with
                  respect thereto are concluded.

         17.2.    The parties  hereby  agree to submit all  Disputes to rules of
                  arbitration of the American  Arbitration  Association  and the
                  Missouri  Uniform  Arbitration  Act (the  "RULES")  under  the
                  following  provisions,  which shall be final and binding  upon
                  the  parties,  their  successors  and  assigns,  and  that the
                  following  provisions  constitute a binding arbitration clause
                  under applicable law. Either party may serve process or notice
                  on the other in any  arbitration  or  litigation in accordance
                  with the notice  provisions  hereof.  The parties agree not to
                  disclose any information  regarding any Dispute or the conduct
                  of any arbitration hereunder,  including the existence of such
                  Dispute or such  arbitration,  to any  person or entity  other
                  than such employees or representatives of such party as have a
                  need to know.

         17.3.    Either party may commence proceedings hereunder by delivery of
                  written  notice  providing  a  reasonable  description  of the
                  Dispute to the other,  including a reference to this provision
                  (the "DISPUTE NOTICE").  Either party may initiate arbitration
                  of  a  Dispute  by   delivery  of  a  demand   therefor   (the
                  "ARBITRATION  DEMAND")  to the other  party not sooner than 60
                  calendar days after the date of delivery of the Dispute Notice
                  but at any time thereafter. The arbitration shall be conducted
                  in St. Louis, Missouri.

         17.4.    The arbitration  shall be conducted by three  arbitrators (the
                  "ARBITRATORS"), one of whom shall be selected by Customer, one
                  by  SAVVIS,  and the third by  agreement  of the other two not
                  later than 10 days  after  appointment  of the first two,  or,
                  failing such agreement, appointed pursuant to the Rules. If an
                  Arbitrator  becomes  unable to  serve,  a  successor  shall be
                  selected  or  appointed  in  the  same  manner  in  which  the
                  predecessor Arbitrator was appointed.

         17.5.    The arbitration shall be conducted pursuant to such procedures
                  as the parties may agree or, in the absence of or failing such
                  agreement,   pursuant  to  the  Rules.   Notwithstanding   the
                  foregoing,  each party  shall  have the right to  inspect  the
                  books and  records  of the  other  party  that are  reasonably
                  related to the  Dispute,  and each party shall  provide to the
                  other,  reasonably  in advance of any  hearing,  copies of all


                                       19
<PAGE>

                  documents  which such party intends to present in such hearing
                  and the names and addresses of all witnesses  whose  testimony
                  such party intends to present in such hearing.

         17.6.    All hearings shall be conducted on an expedited schedule,  and
                  all proceedings shall be confidential. Either party may at its
                  expense make a stenographic record thereof.

         17.7.    The Arbitrators  shall complete all hearings not later than 90
                  calendar days after the Arbitrators' selection or appointment,
                  and shall make a final award not later than 30  calendar  days
                  thereafter.  The  Arbitrators  shall  apportion  all costs and
                  expenses of the Arbitration,  including the Arbitrators'  fees
                  and  expenses  of experts  ("ARBITRATION  COSTS")  between the
                  prevailing and non-prevailing  parties as the Arbitrators deem
                  fair and reasonable. In circumstances where a Dispute has been
                  asserted or defended  against on grounds that the  Arbitrators
                  deem manifestly  unreasonable,  the Arbitrators may assess all
                  Arbitration  Costs  against the  non-prevailing  party and may
                  include in the award the prevailing  party's  attorneys'  fees
                  and expenses in connection with any and all proceedings  under
                  this Section 17.

         17.8.    Either party may assert appropriate  statutes of limitation as
                  a defense in  arbitration;  provided,  that upon delivery of a
                  Dispute  Notice  any  such  statute  shall be  tolled  pending
                  resolution hereunder.

         17.9.    Pending the resolution of any dispute or  controversy  arising
                  under this  Agreement,  the parties shall  continue to perform
                  their respective obligations  hereunder,  and SAVVIS shall not
                  discontinue,  disconnect  or in any  other  fashion  cease  to
                  provide  all or any  substantial  portion of the  Networks  to
                  Customer unless otherwise  directed by Customer.  This Section
                  shall not apply where (a)  Customer  is in default  under this
                  Agreement  or (b)  the  dispute  or  controversy  between  the
                  parties  relates to harm to the Networks  allegedly  caused by
                  Customer and Customer  does not  immediately  cease and desist
                  from the activity giving rise to the dispute or controversy.

18.      FORCE MAJEURE

         18.1.    In no event shall  either party be liable to the other for any
                  failure  to  perform  hereunder  that  is due to  war,  riots,
                  embargoes, strikes or other concerted acts of workers (whether
                  of a party  hereto or of  others),  casualties,  accidents  or
                  other   causes  to  the  extent  that  such  failure  and  the
                  consequences  thereof  are  reasonably  beyond the control and
                  without the fault or negligence of the party claiming  excuse.
                  Each party shall, with the cooperation of the other party, use
                  reasonable  efforts to  mitigate  the extent of any failure to
                  perform and the adverse consequences thereof.

         18.2.    If SAVVIS cannot promptly provide a suitable  temporary SAVVIS
                  alternative  to  all  or  part  of a  Network  subject  to  an
                  interruption  in  connection  with  the  existence  of a force
                  majeure condition,  Customer may, at its option and at its own

                                       20
<PAGE>


                  cost, contract with one or more third parties for the affected
                  portion of the Network for the shortest commercially available
                  period likely to cover the reasonably expected duration of the
                  interruption,  and  may  suspend  SAVVIS'  provision  of  such
                  affected  portion  for such  period.  SAVVIS  shall not charge
                  Customer for the affected  portion thus  suspended  during the
                  period of  suspension.  SAVVIS shall  resume  provision of the
                  suspended  portion  of  the  Network  upon  the  later  of the
                  termination  or  expiration  of  Customer's   legally  binding
                  commitments under contracts with third parties for alternative
                  services  or the  cessation  or remedy  of the  force  majeure
                  condition.

18.3.             In the event that a force majeure condition shall continue for
                  more than 60 days, Customer may cancel the affected portion of
                  the Network with no further liability to SAVVIS other than for
                  obligations  incurred  with respect to such  affected  portion
                  prior to the occurrence of the force majeure condition.

18.4.             The consequences  arising from existence and continuation of a
                  force majeure  condition,  including  without  limitation  any
                  interruption  of the  Networks and the exercise by Customer of
                  its  rights  under  this  Section  18,  shall be deemed not to
                  constitute   a  breach   by   either   party   hereto  of  any
                  representations,  warranties or covenants  hereunder and shall
                  not be grounds  for the  exercise of any  remedies  under this
                  Agreement, including without limitation remedies under Section
                  2.2 or Section 7, other than those  specified  in this Section
                  18.

                  the  parties and their  respective  successors  and  permitted
                  assigns.]  [Except as  expressly  provided in this  Agreement,

                  interests,  or obligations hereunder without the prior written
                  approval  of the  other  party,  which  consent  shall  not be
                  unreasonably withheld.

         19.4.    COUNTERPARTS.  This  Agreement  may be executed in one or more
                  counterparts,  each of which shall be deemed an  original  but
                  all of  which  together  will  constitute  one  and  the  same
                  instrument.

                                  SCHEDULE 2.2
                          QUALITY OF SERVICE STANDARDS

1.       Starting  one year  from  the  Effective  Date,  the  Acquired  Network
         Facilities and Additional  Network Facilities that are connected to the
         St. Louis hub where [Bridge  Parent]/[Telerate  Parent] houses the data
         distributed  over the  Distribution  Network  (the "ST.  LOUIS HUB") by
         fully redundant paths shall be covered by Quality of Service  Standards
         outlined below.  These  provisions  shall be applicable to Installation
         Sites performing within the bandwidth  limitations set forth in Section
         7.2 of Schedule 3.1 to the Network Services  Agreement or, with respect
         to the SAVVIS  Backbone,  to be agreed  upon,  and shall be measured in
         performance relative to the St. Louis Hub.

2.       For  the  SAVVIS  Backbone   supporting  the  Collection   Network  and
         Distribution Network:

         (a)      There shall not be less than 99.99% availability to any SAVVIS
                  POP supporting Installation Sites during each one month period
                  during the Market Hours applicable to the POP connected to the
                  St. Louis Hub.

         (b)      The average  round-trip  terrestrial  latency period to SAVVIS
                  POP  locations  supporting   Installation  Sites  during  each
                  one-month period shall not exceed:

                  (i)    75 milliseconds within the United States,

                  (ii)   250  milliseconds to Australia,  Eastern Asia,  Europe,
                         and North America,

                  (iii)  425  milliseconds  to all other areas,  including South
                         America, Middle East, Africa, New Zealand and India.

3.       For Installation Sites, network availability shall be measured in terms
         of server upstream  connectivity during Market Hours for each one-month
         period.  Resultant  availability to the Installation Sites shall be not
         less than 99.99% based on the following criteria:

         (a)      All server disconnects will be considered as potential network
                  outages.

         (b)      Disconnects  which are  attributed  to bandwidth  limitations,
                  process  failures,  and server faults will be eliminated  from
                  the sample population.

         (c)      Remaining  disconnects that reflect total outage conditions on
                  both  redundant  pieces of the network  shall be  considered a
                  network outage to the Installation  Site. The time duration of
                  the network outage shall be used to determine the availability
                  percentage.

                                       24

3.       SAVVIS will continue to monitor performance of the acquired Customer OA
         Network.  Performance  problems with specific OA sites will be resolved
         jointly by Customer and SAVVIS.

4.       CREDIT AMOUNTS

         Amounts to be credited if the Quality of Service  Standards are not met
         with respect to a particular Installation Site in any month shall be as
         follows during the first  Agreement  Year,  according to the connection
         speed at such Installation Site:

                  deemed  to  be  one  month's   charges   applicable   to  such

                  month; provided,  however, that Telerate shall not be entitled
                  to such  credit to the  extent  that the  failure  to meet the
                  Quality of Service Standards with respect to such Installation
                  Site  is  due to (i) an  act  or  omission  of  Telerate  or a
                  Telerate  Subsidiary  or a vendor or customer of Telerate or a
                  Telerate  Subsidiary  or (ii)  equipment  or software  used by
                  Telerate and not provided by SAVVIS.  Not more than one credit
                  of  one  month's  charges  shall  be  given  for a  particular
                  Installation  Site for a  particular  month.  The  Quality  of

                  month shall be deemed to have been met unless  Bridge,  within
                  30 days of its  receipt  of the  performance  report  for such
                  Installation Site for such month, requests in writing a credit
                  as set forth above with respect to such  Installation Site for
                  such month.


         2.3.     SAVVIS  agrees  that,  for the  term of  this  Agreement,  the
                  network  operations  centers for the Networks shall be managed
                  by Bridge under the Technical  Services  Agreement;  provided,
                  however,  that SAVVIS shall not be restricted  from  building,
                  managing and operating one or more network  operations centers
                  for such portions of the SAVVIS  Backbone or other  operations
                  of  SAVVIS  that  are not  used to  provide  the  Networks  to
                  Telerate.

         2.4.     [Intentionally omitted.]

         2.5.     Unless otherwise mutually agreed by the parties, each Addendum
                  providing for the provision of Additional  Network  Facilities
                  shall  have a term of  three  years.  Such  Addendum  may also
                  include  provisions with respect to the level of redundancy to
                  be provided  and the Quality of Service  Standards to apply to
                  such Additional Network  Facilities.  In providing  Additional
                  Network  Facilities,  SAVVIS agrees to use its best efforts to
                  expedite the  provisioning of the circuits for such Additional
                  Network  Facilities  in those  instances  in which  SAVVIS  is
                  responsible for provisioning such circuits.

         2.6.     Throughout  the term of this  Agreement,  SAVVIS shall use its
                  commercially  reasonable  best efforts to continue to meet the
                  requests of Telerate to enhance the total capacity, geographic
                  extension  and  performance  quality of the  Networks,  and to
                  maintain  its  research  and  development  effort  at a  level
                  appropriate  to sustain  the ability of Telerate to compete on
                  the basis of the quality of the Networks.

                                       6

         2.7.     The parties acknowledge that SAVVIS intends to replace certain
                  existing  routers among the Acquired  Network  Facilities (the
                  "REPLACED  ROUTERS")  with new  equipment  promptly  after the
                  Effective  Date.  It is the  intention of the parties that the
                  Replaced Routers will be re-deployed at Installation  Sites at
                  which  one or more  56 Kbps  ports  or 64 Kbps  ports  will be
                  provided by SAVVIS using Additional  Network Facilities as set
                  forth in Section 3.1 hereof.  SAVVIS  agrees to manage the use
                  of its  inventory of routers in order to re-deploy the maximum
                  number of Replaced Routers as is commercially  reasonable.  So
                  long as  Replaced  Routers  are  available  for  re-deployment
                  during the 18 months  following  the  Effective  Date,  SAVVIS
                  agrees not to make any bulk  purchases of  additional  routers
                  without the prior written consent of Telerate,  which will not
                  be  unreasonably  withheld.  Upon the  expiration of 18 months
                  following the Effective  Date, the parties shall determine the
                  number of Replaced Routers that the parties mutually agree are
                  likely to be so re-deployed within the succeeding 12 months.

3.       RATES AND CHARGES

         3.1.     Telerate  shall pay SAVVIS for the Networks using the Acquired
                  Network Facilities and Additional Network Facilities according
                  to the rates and charges set forth in Schedule 3.1 hereof.

         3.2.     The parties  recognize that certain  savings might be obtained
                  by consolidating the multiple Local Access Facilities that are
                  provided at such building  locations on the Effective Date. In
                  the event that SAVVIS  consolidates  the multiple Local Access
                  Facilities  at one or  more  of such  building  locations  and
                  obtains  cost  savings as a result  thereof,  the parties will
                  mutually agree within 30 days following such  consolidation on
                  the  manner in which  such  savings  shall be  shared  between
                  SAVVIS and Telerate, if only Telerate or Telerate Subsidiaries
                  use those  consolidated  Local Access  Facilities,  or between
                  SAVVIS,  Telerate  and  Bridge,  if both  Telerate or Telerate
                  Subsidiaries  and  Bridge or any  subsidiaries  of Bridge  use
                  those  consolidated  Local Access  Facilities.  Any  reduction
                  pursuant to this Section  shall not affect the Minimum  Annual
                  Commitment.

         3.3.     For  any  Installation  Site  to  which  SAVVIS  is  providing
                  services  both under  this  Agreement  and the Bridge  Network
                  Services  Agreement,  the rates and charges applicable to such
                  Installation  Site under this  Agreement  shall be one-half of
                  the rates and charges that would  otherwise be  applicable  to
                  such Installation Site under this Agreement.

4.       STRATEGIC ADVISORY COMMITTEE

         4.1.     According to the Bridge Network Services Agreement,  within 30
                  days after the  Effective  Date,  SAVVIS and Bridge  will each
                  appoint  three senior  executives to the  "STRATEGIC  ADVISORY
                  COMMITTEE,"  and  one  outside   consultant  will  be  jointly
                  appointed by both parties.

         4.2.     The mission of the  Strategic  Advisory  Committee  will be to
                  review the performance of the Networks,  to serve as forum for
                  the  consideration  and  discussion of issues raised by either
                  SAVVIS or Bridge with respect to the Networks,  and to discuss
                  issues related to the future development of the data transport
                  and Internet  Protocol  backbone  operations  of SAVVIS in the
                  context of the relationship of SAVVIS, Telerate and Bridge.

5.       INVOICES

         5.1.     The amounts due to SAVVIS from Telerate for the  installation,
                  operation, management and maintenance of the Networks shall be
                  billed  monthly  in  advance.  All items on  invoices  not the
                  subject of a bona fide dispute shall be payable by Telerate in
                  United States currency within 30 days from the date of receipt
                  of the  invoice.  All  amounts  not in dispute  are subject to
                  interest  charges of 1-1/2  percent  that will accrue daily on
                  all  amounts not paid within 30 days of the date of receipt of
                  the invoice.

         5.2.     At any time and from time to time,  Telerate  may,  by written
                  notice to SAVVIS,  have one or more Installation Sites removed
                  from  the  Networks.  Each  monthly  invoice  from  SAVVIS  to
                  Telerate  shall  reflect a reduction in the amount  charged to
                  Telerate for the Networks  resulting  from any such removal of
                  Installation  Sites.  In the  case  of any  Installation  Site
                  removed from the Acquired Network  Facilities,  such reduction
                  shall be the sum of:

                  (a)      the  actual  cost  of  the  Local  Access  Facilities
                           connecting  the Acquired  Network  Facilities to such
                           Installation  Site,  effective  as of  such  time  as
                           SAVVIS is no longer required to pay such costs, and

                  (b)      the  amounts  set  forth  on  Schedule  5.2  attached
                           hereto,  which are deemed to be one  month's  charges
                           applicable  to  such  Installation  Site  under  this
                           Agreement with respect to such month during the first
                           Agreement Year, according to connection speed at such
                           Installation Site,  effective as of such time as such
                           Installation Site is disconnected from the Networks.

         5.3.     Telerate shall pay any sales,  use,  federal excise,  utility,
                  gross receipts,  state and local  surcharges,  value added and
                  similar  taxes,  charges or levies  lawfully  levied by a duly
                  constituted taxing authority against or upon the Networks.  In
                  the   alternative,   Telerate  shall  provide  SAVVIS  with  a
                  certificate evidencing Telerate's exemption from payment of or
                  liability for such taxes. All other taxes,  charges or levies,
                  including  any ad valorem,  income,  franchise,  privilege  or
                  occupation taxes of SAVVIS shall be paid by SAVVIS.

         5.4.     Bona fide disputes  concerning  invoices  shall be referred to
                  the parties' respective  representatives who are authorized to
                  resolve such matters. Any amount to which Telerate is entitled
                  as a result of the  resolution  of a billing  dispute shall be
                  credited promptly to Telerate's  account.  Any amount to which
                  SAVVIS is

                                       8
<PAGE>

                  entitled as a result of the  resolution  of a billing  dispute
                  shall be paid promptly to SAVVIS.

         5.5.     Against  the amounts  owed by  Telerate  to SAVVIS  under this
                  Agreement, Telerate shall have the right to offset any amounts
                  owed by SAVVIS to Telerate under this  Agreement,  and against
                  any amounts owed by SAVVIS to Bridge under the Bridge  Network
                  Services  Agreement,  the  Technical  Services  Agreement,  or
                  otherwise,  including  without  limitation any amounts paid by
                  Bridge  on  behalf of  SAVVIS  under  guarantees  by Bridge of
                  obligations of SAVVIS.

6.       TERM AND EXTENSIONS

         6.1.     This Agreement  shall commence on the Effective Date and shall
                  continue in full force and effect for the Initial  Term unless
                  terminated  or  extended  in  accordance  with the  provisions
                  hereof.

         6.2.     The term of this Agreement may be extended by Telerate for one
                  additional  five-year  period by giving SAVVIS  written notice
                  not less than one year before the scheduled  expiration of the
                  Initial Term.

         6.3.     Upon the  termination of this Agreement in accordance with its
                  scheduled  expiration  or by  Telerate  pursuant to Section 7,
                  SAVVIS will  continue to provide  the  Networks in  accordance
                  with the terms and  conditions  herein  (excluding the Minimum
                  Annual  Commitment) for a period of up to five years after the
                  effective  date  of  termination  (the  "TRANSITION  PERIOD").
                  During the  Transition  Period,  Telerate shall pay SAVVIS for
                  the use of the Networks at the rates in effect for third party
                  customers of SAVVIS at the effective date of  termination.  If
                  Telerate has not completely  transitioned  from its use of the
                  Networks after the Transition Period,  SAVVIS will provide the
                  Networks at SAVVIS' then  current  list rates.  SAVVIS and its
                  successor  will  cooperate  with Telerate  until  Telerate has
                  completely migrated to another provider.

7.       TERMINATION BY TELERATE

         7.1.     An "EVENT OF DEFAULT BY SAVVIS" shall be deemed to occur if:

                  (a)      SAVVIS has failed to a material  degree to perform or
                           comply with or has violated to a material  degree any
                           material representation, warranty, term, condition or
                           obligation of SAVVIS under this Agreement, and SAVVIS
                           has failed to cure such failure or  violation  within
                           60 days after receiving notice thereof from Telerate;
                           or

                  (b)      SAVVIS   becomes  the  subject  of  a  voluntary   or
                           involuntary bankruptcy, insolvency, reorganization or
                           liquidation  proceeding,  makes an assignment for the
                           benefit  of  creditors,  or  admits  in  writing  its
                           inability to pay debts when due; or

                                       9
<PAGE>

                  (c)      an Event of Default by SAVVIS occurs under the Bridge
                           Network Services Agreement.

         7.2.     Telerate  shall have the right to  terminate  this  Agreement,
                  with no liability  to SAVVIS other than for charges  (less any
                  applicable  credits) for the Networks  provided  prior to such
                  termination, if:

                  (a)      Telerate  provides  written notice to SAVVIS,  at any
                           time  after the ninth  anniversary  of the  Effective
                           Date,  of  Telerate's   intent  to  terminate,   such
                           termination  to be  effective  not less than one year
                           following the date of such notice; or

                  (b)      Telerate  provides  10  days  written  notice  of its
                           intent to  terminate  in the  event  that an Event of
                           Default by SAVVIS occurs.

         7.3.     For  purposes  of Section  7.1(a),  if the  Quality of Service
                  Standards   are  not  met  with   respect   to  a   particular
                  Installation Site in any month, SAVVIS shall be deemed to have
                  cured such  failure  within 60 days if the  Quality of Service
                  Standards  are met with respect to such  Installation  Site in
                  the  following  month.  A failure  of the  Quality  of Service
                  Standards to be met shall not  constitute  an Event of Default
                  or give Telerate the right to terminate  this Agreement to the
                  extent  that such  failure is due to (i) an act or omission of
                  Telerate or a Telerate  Subsidiary  or a vendor or customer of
                  Telerate  or  a  Telerate  Subsidiary  or  (ii)  equipment  or
                  software  used by Telerate  and not  provided  by SAVVIS.  The
                  parties  acknowledge and agree that the failure of the Quality
                  of  Service  Standards  to be met with  respect to one or more
                  Installation  Sites in one or more  months  may,  but does not
                  necessarily,  constitute  a failure  by  SAVVIS to a  material
                  degree to perform or comply with, or a violation to a material
                  degree  of,  any  material  representation,   warranty,  term,
                  condition or obligation of SAVVIS under this Agreement.

         7.4.     As  provided  in  Section   2.2,  for  all  purposes  of  this
                  Agreement,  including without  limitation the determination of
                  an Event of Default by SAVVIS under this Section,  the Quality
                  of Service Standards  applicable to a particular  Installation
                  Site in any month  shall be  deemed  to have  been met  unless
                  Telerate,  within 30 days of its  receipt  of the  performance
                  report of such Installation  Site for such month,  requests in
                  writing a credit as set forth in Section  2.2 with  respect to
                  such Installation Site for such month.

8.       TERMINATION BY SAVVIS

         8.1.     SAVVIS shall have the right to terminate this Agreement if:

                  (a)      Telerate  has failed to pay any  invoice  that is not
                           the subject of a bona fide dispute  within 60 days of
                           the date on which such  payment is due and SAVVIS has
                           provided   Telerate  with  written  notice   thereof,
                           provided that

                                       10
<PAGE>

                           Telerate  shall have a further 30 days from  the time
                           it receives such notice from SAVVIS of nonpayment  to
                           cure any such default;

                  (b)      SAVVIS  provides 10 days written notice of its intent
                           to terminate in the event that Telerate has failed to
                           perform or comply with or has  violated  any material
                           representation,    warranty,   term,   condition   or
                           obligation  of  Telerate  under this  Agreement,  and
                           Telerate has failed to cure such failure or violation
                           within 60 days after  receiving  notice  thereof from
                           SAVVIS;

                  (c)      Telerate  becomes  the  subject  of  a  voluntary  or
                           involuntary bankruptcy, insolvency, reorganization or
                           liquidation  proceeding,  makes an assignment for the
                           benefit  of  creditors,  or  admits  in  writing  its
                           inability to pay debts when due; or

                  (d)      SAVVIS  becomes  entitled  to  terminate  the  Bridge
                           Network  Services  Agreement  pursuant  to the  terms
                           thereof.

         8.2.     Notwithstanding the provisions of Section 8.1(b) above, SAVVIS
                  shall not have the right to  terminate  this  Agreement  under
                  Section  8.1(b) solely for a failure by Telerate to perform or
                  comply with, a violation  by Telerate of, the  obligations  of
                  Telerate under Section 15 (Confidentiality) of this Agreement,
                  without prejudice,  however, to such rights as SAVVIS may have
                  pursuant to such  Section  and to such rights and  remedies to
                  which  SAVVIS may be  entitled,  at law or in  equity,  as the
                  result of an actual or  threatened  breach by Telerate of such
                  Section.

9.       ACCEPTANCE OF ADDITIONAL NETWORK FACILITIES

         9.1.     Upon the installation of Additional  Network Facilities at any
                  Installation  Site, SAVVIS shall conduct  appropriate tests to
                  establish that such Additional  Network  Facilities perform in
                  accordance  with  mutually  agreed  upon  acceptance  criteria
                  ("ACCEPTANCE  CRITERIA") set forth in the applicable  Addendum
                  entered  into  pursuant  to Section  2.5,  and shall  promptly
                  inform  Telerate of such test  results.  If test  results show
                  that the  Additional  Network  Facilities  are  performing  in
                  accordance  with the  Acceptance  Criteria,  Telerate shall be
                  deemed to accept  the  Additional  Network  Facilities  at the
                  Installation Site immediately.

         9.2.     If SAVVIS' tests  establish  that newly  installed  Additional
                  Network  Facilities at the Installation Site do not perform in
                  accordance with the mutually agreed upon Acceptance  Criteria,
                  then SAVVIS shall  immediately  and diligently  exert its best
                  efforts to bring the  Additional  Network  Facilities  at such
                  Installation  Site  into  compliance.  SAVVIS  shall  not bill
                  Telerate  for  the  Additional   Network  Facilities  at  such
                  Installation  Site  until  the  test  results  show  that  the
                  Additional  Network  Facilities  are  performing in accordance
                  with the Acceptance Criteria.

         9.3.     Upon repair or restoration of any part of the Networks, SAVVIS
                  shall conduct appropriate tests to establish that the Networks
                  perform in  accordance  with

                                       11
<PAGE>

                  mutually  agreed upon  Acceptance  Criteria and shall promptly
                  inform Telerate of such test results.

10.      RIGHTS AND OBLIGATIONS OF TELERATE

         10.1.    SITE PREPARATION.  For the installation of Additional  Network
                  Facilities,  Telerate shall,  at its own expense,  provide all
                  necessary preparations of each Installation Site in accordance
                  with  the  requirements  to be  mutually  agreed  upon  by the
                  parties and set forth in an Addendum hereto,  including inside
                  wiring,  demarcation  extension  and rack  mount  accessories.
                  Telerate  shall  ensure that  Telerate-provided  equipment  is
                  on-site  by the  scheduled  installation  date.  If  SAVVIS is
                  required to reschedule the  installation of  Telerate-provided
                  equipment   because  it  is  not  on-site  by  the   scheduled
                  installation  date,  Telerate  shall pay SAVVIS to  redispatch
                  installation personnel.

         10.2.    PROPER USE OF NETWORKS.

                  10.2.1.  Telerate  shall use any equipment  provided by SAVVIS
                           in connection  with the Networks in  accordance  with
                           its  documentation,   which  documentation  shall  be
                           provided by SAVVIS at no  additional  charge.  Unless
                           otherwise  provided  herein,  upon the termination of
                           this Agreement Telerate shall surrender to SAVVIS the
                           equipment  provided by SAVVIS, in good working order,
                           ordinary wear and tear excepted.

                  10.2.2.  Telerate  shall be liable for damages to the Networks
                           caused by the negligence or willful acts or omissions
                           of   Telerate's   officers,   employees,   agents  or
                           customers, for loss through theft or vandalism of the
                           Networks at the Installation Site, and for damages to
                           the  Networks  caused  by  the  use of  equipment  or
                           supplies  not  provided  hereunder  or not  otherwise
                           authorized by SAVVIS.

                  10.2.3.  Telerate  shall  neither  permit nor assist others to
                           use the Networks for any purpose  other than that for
                           which  they  are  intended,  nor fail to  maintain  a
                           suitable  environment  specified  by  SAVVIS  in  the
                           applicable  schedule,  nor alter, tamper with, adjust
                           or  repair  the   Networks.   Any  such   alteration,
                           tampering,  adjustment  or repair by  Telerate  shall
                           relieve  SAVVIS  from  any  liability  or  obligation
                           hereunder   (including   any  warranty  or  indemnity
                           obligation)  relating to the  affected  Network,  and
                           Telerate shall be liable to SAVVIS for any documented
                           direct  costs  incurred by SAVVIS as a result of such
                           actions.

         10.3.    ABUSE OR FRAUDULENT USE OF NETWORKS.  Telerate shall not abuse
                  or fraudulently use the Networks,  or use the Networks for any
                  unauthorized or illegal purposes, and shall neither permit nor
                  assist others to do so, including but not limited to:

                                       12
<PAGE>

                  (a)      obtaining  or  attempting  to obtain  service  by any
                           fraudulent means or device to avoid payment; or

                  (b)      accessing,  altering or destroying any information of
                           another party by any fraudulent  means or device,  or
                           attempting to do so; or

                  (c)      using the Networks so as to interfere with the use of
                           the  SAVVIS  network  by other  SAVVIS  customers  or
                           authorized users or in violation of law or in support
                           of any unlawful act; or

                  (d)      using the  Networks for voice  communications  over a
                           private  network in  jurisdictions  where such use is
                           not allowed; or

                  (e)      using  the  Networks  in  a  manner  contrary  to  or
                           inconsistent  with such  acceptable  use  policies as
                           SAVVIS  may  adopt  and  publish  from  time  to time
                           consistent with industry standards.

                  Notwithstanding  the  provisions of Section 8, upon the breach
                  of this Section 10.3 by Telerate,  SAVVIS shall have the right
                  to terminate this Agreement with respect to all or part of the
                  Networks immediately upon written notice to Telerate.

         10.4.    COVENANT NOT TO COMPETE.

                  10.4.1.  As  an  inducement  to  SAVVIS  to  enter  into  this
                           Agreement,  which Telerate acknowledges is of benefit
                           to it,  and in  consideration  of  the  promises  and
                           representations   of  SAVVIS  under  this  Agreement,
                           Telerate covenants and agrees that during the term of
                           this  Agreement  and  for  a  period  of  five  years
                           thereafter,   neither   Telerate   nor   any  of  its
                           successors or assigns will,  directly or  indirectly,
                           engage in, or have any interest in any other  person,
                           firm,  corporation  or other  entity  engaged in, any
                           business activities anywhere in the world competitive
                           with  or  similar  or  related  to  the   packet-data
                           transport  network services  provided by SAVVIS under
                           this Agreement;  provided, however, that (i) Telerate
                           and  the  Telerate  Subsidiaries  shall  be  free  to
                           continue  to use the Call  Assets  and the  satellite
                           networks currently used by Telerate,  until such Call
                           Assets or satellite  networks  have been  acquired by
                           SAVVIS or the  SAVVIS  Subsidiaries  pursuant  to the
                           Master  Establishment and Transition  Agreement,  and
                           (ii)   Telerate   shall  be  free  to  make   passive
                           investments  in securities of companies  that provide
                           network services in competition with SAVVIS which, in
                           the case of any such  security,  does not  constitute
                           more than ten percent (10%) of the total  outstanding
                           amount of such security.

                  10.4.2.  If any court or  tribunal of  competent  jurisdiction
                           shall refuse to enforce one or more of the  covenants
                           in  this   Section   10.4   because  the  time  limit
                           applicable  thereto  is  deemed  unreasonable,  it is
                           expressly understood and agreed that such covenant or
                           covenants  shall not be void but that for the

                                       13
<PAGE>

                           purpose  of such  proceedings  such  time  limitation
                           shall be deemed to be reduced to the extent necessary
                           to  permit  the   enforcement  of  such  covenant  or
                           covenants.

                  10.4.3.  If any court or  tribunal of  competent  jurisdiction
                           shall  refuse to enforce any or all of the  covenants
                           in this Section 10.4 because,  taken  together,  they
                           are more  extensive  (whether as to geographic  area,
                           scope of business or otherwise)  than is deemed to be
                           reasonable,  it is  expressly  understood  and agreed
                           between  the  parties  hereto  that such  covenant or
                           covenants  shall not be void but that for the purpose
                           of  such  proceedings  the   restrictions   contained
                           therein  (whether  as to  geographic  area,  scope of
                           business or otherwise)  shall be deemed to be reduced
                           to the extent  necessary to permit the enforcement of
                           such covenant or covenants.

10.4.4.                    Telerate  specifically  acknowledges  and agrees that
                           the foregoing  covenants are commercially  reasonable
                           and reasonably  necessary to protect the interests of
                           SAVVIS hereunder.  Telerate hereby  acknowledges that
                           SAVVIS and its  successors  and  assigns  will suffer
                           irreparable  and  continuing  harm to the extent that
                           any of the  foregoing  covenants is breached and that
                           legal  remedies  would be  inadequate in the event of
                           any such breach.

11.      RIGHTS AND OBLIGATIONS OF SAVVIS

         11.1.    PROVISION OF THE NETWORKS.  SAVVIS shall operate, maintain and
                  manage  the  Networks  at the  Installation  Sites  using  the
                  Acquired Network  Facilities in accordance with the Quality of
                  Service Standards and other terms of this Agreement, including
                  all Addenda hereto.

         11.2.    REPRESENTATIONS AND WARRANTIES.

                  11.2.1.  [Intentionally omitted.]

                  11.2.2.  SAVVIS hereby  represents and warrants that the terms
                           hereof do not conflict in any respect whatsoever with
                           any   SAVVIS   tariff  on  file   with  the   Federal
                           Communications  Commission or other  regulatory body.
                           If, during the term of this  Agreement,  SAVVIS shall
                           file  a  contract   specific  tariff   governing  the
                           Networks or any portion  thereof,  such tariff filing
                           shall be consistent in all respects with the terms of
                           this  Agreement,  and SAVVIS  shall give  Telerate 10
                           days advance  written  notice of making such a tariff
                           filing  and of filing  any  subsequent  modifications
                           thereto.

                  11.2.3.  THE  FOREGOING  WARRANTIES  ARE IN LIEU OF ALL  OTHER
                           WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED
                           WARRANTIES  OF  MERCHANTABILITY  AND  FITNESS  FOR  A
                           PARTICULAR PURPOSE.


                                       14
<PAGE>


         11.3.    So  long  as  Bridge  is the  beneficial  owner  of 20% of the
                  outstanding voting securities of SAVVIS Parent,  SAVVIS Parent
                  shall not,  without the prior written consent of Bridge,  take
                  any action or otherwise enter into any agreement,  arrangement
                  or understanding, including without limitation the creation or
                  issuance  of any  class of stock  or  other  security,  or any
                  agreement with any shareholder of SAVVIS Parent, the effect of
                  which would be to provide  any  shareholder  of SAVVIS  Parent
                  with any voting or registration  rights superior to the voting
                  or  registration  rights of Bridge,  other than as required by
                  law.

         11.4.    SAVVIS acknowledges that the occurrence of Event of Default by
                  SAVVIS,  arising  from either (i) a failure of the Networks to
                  meet  Quality  of  Service  Standards  or (ii) a total loss to
                  Telerate of the use of the Networks,  could cause  irreparable
                  harm to  Telerate,  the  amount of which may be  difficult  to
                  determine,  thus  potentially  making  any remedy at law or in
                  damages inadequate.  SAVVIS,  therefore,  agrees that Telerate
                  shall  have  the  right to  apply  to any  court of  competent
                  jurisdiction  for injunctive  relief upon the occurrence of an
                  Event of  Default  by  SAVVIS  or the  occurrence  of an event
                  which, with the passage of time or the giving of notice, could
                  become  an  Event  of  Default  by  SAVVIS  and for any  other
                  appropriate  relief.  This right  shall be in  addition to any
                  other remedy  available  to Telerate in law or equity.  SAVVIS
                  further  agrees  that,  upon  the  occurrence  of an  Event of
                  Default by SAVVIS, SAVVIS shall pay to Telerate, as liquidated
                  damages and not as a penalty, an amount equal to the lesser of
                  (a) the  aggregate  amounts  paid by Telerate to SAVVIS  under
                  this Agreement  during the six months  preceding such Event of
                  Default by SAVVIS or (b) $50,000,000;  provided, however, that
                  Telerate  may recover  liquidated  damages  under this Section
                  only for an Event of Default by SAVVIS  that  occurs (i) prior
                  to any Event of Default by SAVVIS for which Telerate or Bridge
                  or any  Telerate  Subsidiary  or  any  Bridge  Subsidiary  has
                  claimed  liquidated  damages  under this  Section or under the
                  Bridge Network  Services  Agreement or under any Local Network
                  Services  Agreement or under any Bridge Local Network Services
                  Agreement,  or (ii)  more than 36  months  following  the most
                  recent Event of Default by SAVVIS for which Telerate or Bridge
                  or any  Telerate  Subsidiary  or  any  Bridge  Subsidiary  has
                  claimed  liquidated  damages  under this  Section or under the
                  Bridge Network  Services  Agreement or under any Local Network
                  Services   Agreement  or  under  any  Telerate  Local  Network
                  Services Agreement.

12.      LIMITATIONS OF LIABILITY

         12.1.    Subject to Section 11.4,  neither party shall be liable to the
                  other  for  indirect,  incidental,  consequential,  exemplary,
                  reliance  or  special  damages,  including  damages  for  lost
                  profits, regardless of the form of action whether in contract,
                  indemnity,  warranty,  strict  liability  or  tort,  including
                  negligence  of any kind with  respect to the Networks or other
                  conduct under this Agreement.

         12.2.    Nothing  contained in this Section shall limit either  party's
                  liability  to  the  other  for  (a)  willful  or   intentional
                  misconduct, including fraud, or (b) injury or death, or damage
                  to  tangible  real  or  tangible   personal  property  or  the
                  environment,  when proximately caused by SAVVIS' or Telerate's
                  negligence or that of their respective agents,  subcontractors
                  or  employees.  Nothing  contained in this Section shall limit
                  SAVVIS'  intellectual  property  indemnification   obligations
                  under Section 16.1 or Telerate's  indemnification  obligations
                  with respect to a breach of Section 10.3.

13.      EQUIPMENT AND SOFTWARE NOT PROVIDED BY SAVVIS

         13.1.    SAVVIS  shall  not  be  responsible   for  the   installation,
                  operation or maintenance of equipment or software not provided
                  by it under this  Agreement,  nor shall SAVVIS be  responsible
                  for the  transmission or reception of information by equipment
                  or software  not  provided by SAVVIS  hereunder.  In the event
                  that  Telerate  uses  equipment  or software  not  provided by
                  SAVVIS  hereunder in a manner that impairs  Telerate's  use of
                  the Networks,  Telerate  shall not be excused from payment for
                  such use and SAVVIS shall not be  responsible  for any failure
                  of the  Networks  to meet the  Quality  of  Service  Standards
                  resulting  from  the  use of such  equipment  or  software  by
                  Telerate.  Upon  notice  from  SAVVIS  that the  equipment  or
                  software  not  provided  by SAVVIS  under  this  Agreement  is
                  causing or is likely to cause hazard,  interference or service
                  obstruction,  Telerate shall  eliminate the likelihood of such
                  hazard, interference or service obstruction.

         13.2.    Notwithstanding the foregoing,  SAVVIS shall, at no additional
                  charge, provide all interface  specifications for the Networks
                  reasonably  requested  by  Telerate.  SAVVIS  shall,  upon the
                  receipt of appropriate  specifications  from Telerate,  inform
                  Telerate  of  the  compatibility  with  the  Networks  of  any
                  equipment  or  software  that  Telerate  proposes  to  use  in
                  connection therewith,  the effects, if any, of the use of such
                  equipment    or   software   on   the    quality,    operating
                  characteristics  and  efficiency  of  the  Networks,  and  the
                  effects,   if  any,   of  the   Networks   on  the   operating
                  characteristics  and  efficiency  of  any  such  equipment  or
                  software.

14.      PROPRIETARY RIGHTS; LICENSE

         14.1.    SAVVIS hereby grants to Telerate and the Telerate Subsidiaries
                  a  non-exclusive  and  non-transferable  license  to  use  all
                  programming  and  software  necessary  for  Telerate  and  the
                  Telerate  Subsidiaries  to use the  Networks.  Such license is
                  granted for the term of this Agreement for the sole purpose of
                  enabling  Telerate  and the Telerate  Subsidiaries  to use the
                  Networks.

         14.2.    All title and property rights (including intellectual property
                  rights) to the Networks (including associated  programming and
                  software) are and shall remain with SAVVIS or the  third-party
                  providers  thereof to SAVVIS.  Telerate  shall not  (except as
                  permitted by applicable law) attempt to examine,  copy, alter,
                  reverse

                                       16

                  engineer,  decompile,  disassemble,  tamper with or  otherwise
                  misuse the Networks, programming and software.

15.      CONFIDENTIALITY

         15.1.    During  the term of this  Agreement  and for a period  of five
                  years  from  the  date  of  its   expiration  or   termination
                  (including  all  extensions  thereof),  each  party  agrees to
                  maintain in strict  confidence all  Confidential  Information.
                  Neither  party shall,  without  prior  written  consent of the
                  other party,  use the other party's  Confidential  Information
                  for any purpose other than for the  performance  of its duties
                  and  obligations,  and the exercise of its rights,  under this
                  Agreement.   Each  party  shall  use,   and  shall  cause  all
                  authorized   recipients  of  the  other  party's  Confidential
                  Information  to use,  the same  degree of care to protect  the
                  other party's  Confidential  Information as it uses to protect
                  its own  Confidential  Information,  but in any event not less
                  than a reasonable degree of care.

         15.2.    Notwithstanding  Section  15.1,  either party may disclose the
                  Confidential  Information  of the  other  party  to:  (a)  its
                  employees  and the  employees,  directors  and officers of its
                  Affiliates  as  necessary  to implement  this  Agreement;  (b)
                  employees,  agents or  representatives  of the other party; or
                  (c) other persons (including counsel, consultants,  lessors or
                  managers of  facilities  or  equipment  used by such party) in
                  need of access to such  information for purposes  specifically
                  related  to  either   party's   responsibilities   under  this
                  Agreement,   provided  that  any  disclosure  of  Confidential
                  Information  under  clause  (c) shall be made only upon  prior
                  written  approval  of  the  other  party  and  subject  to the
                  appropriate  assurances that the recipient of such information
                  shall hold it in strict confidence.

         15.3.    Upon the  request of the party  having  proprietary  rights to
                  Confidential  Information,  the  party in  possession  of such
                  information  shall  promptly  return it (including any copies,
                  extracts and  summaries  thereof,  in whatever form and medium
                  recorded) to the  requesting  party or, with the other party's
                  written  consent,  shall  promptly  destroy it and provide the
                  other party with written certification of such destruction.

         15.4.    Either party may request in writing that the other party waive
                  all or any portion of the requesting party's  responsibilities
                  relative to the other party's Confidential  Information.  Such
                  waiver request shall identify the affected information and the
                  nature of the proposed  waiver.  The  recipient of the request
                  shall respond within a reasonable  time and, if it determines,
                  in its sole discretion, to grant the requested waiver, it will
                  do so in writing over the signature of an employee  authorized
                  to grant such request.

         15.5.    Telerate  and  SAVVIS   acknowledge  that  any  disclosure  or
                  misappropriation  of Confidential  Information in violation of
                  this  Agreement  could cause  irreparable  harm, the amount of
                  which may be difficult to determine,  thus potentially  making

                                       17
<PAGE>

                  any  remedy  at  law or in  damages  inadequate.  Each  party,
                  therefore, agrees that the other party shall have the right to
                  apply to any  court  of  competent  jurisdiction  for an order
                  restraining  any breach or  threatened  breach of this Section
                  and for any other appropriate  relief.  This right shall be in
                  addition to any other remedy available in law or equity.

         15.6.    A party requested or ordered by a court or other  governmental
                  authority  of  competent   jurisdiction  to  disclose  another
                  party's Confidential  Information shall notify the other party
                  in  advance  of any such  disclosure  and,  absent  the  other
                  party's  consent to such  disclosure,  use its best efforts to
                  resist,  and to assist  the  other  party in  resisting,  such
                  disclosure.  A party providing  another  party's  Confidential
                  Information to a court or other  governmental  authority shall
                  use  its  best  efforts  to  obtain  a  protective   order  or
                  comparable  assurance  that the  Confidential  Information  so
                  provided will be held in confidence and not further  disclosed
                  to any other person, absent the owner's prior consent.

         15.7.    The  provisions  of  Section  15.1  above  shall  not apply to
                  reasonably  necessary  disclosures  in or in  connection  with
                  filings  under any  securities  laws,  regulatory  filings  or
                  proceedings,  financial  disclosures  which in the good  faith
                  judgment  of  the  disclosing   party  are  required  by  law,
                  disclosures   required  by  court  or  tribunal  or  competent
                  jurisdiction,  or disclosures that may be reasonably necessary
                  in connection  with the sale of securities or the  performance
                  or  enforcement  of this  Agreement or any of the  obligations
                  hereof;  provided,  however, that if the receiving party would
                  otherwise  be required  to refer to or describe  any aspect of
                  this  Agreement  in any of the  preceding  circumstances,  the
                  receiving party shall use its reasonable  efforts to take such
                  steps as are available  under such  circumstances  (such as by
                  providing a summary or  synopsis) to avoid  disclosure  of the
                  financial    terms   and   conditions   of   this   Agreement.
                  Notwithstanding  any  provisions  of  this  Agreement  to  the
                  contrary,  either party may disclose the terms and  conditions
                  of this  Agreement  in the  course of a due  diligence  review
                  performed in connection  with  prospective  debt  financing or
                  equity  investment by, or a sale to, a third party, so long as
                  the persons  conducting such due diligence  review have agreed
                  to maintain the  confidentiality of such disclosure and not to
                  use such  disclosure  for any purpose other such due diligence
                  review.

16.      INDEMNIFICATIONS

         16.1.    SAVVIS shall defend,  settle,  or otherwise  manage at its own
                  cost and expense any claim or action  against  Telerate or any
                  of its directors, officers, employees or assigns for actual or
                  alleged infringement by the Networks of any patent, copyright,
                  trademark,  trade secret or similar  proprietary  right of any
                  third party,  except to the extent that such actual or alleged
                  infringement   arises   from  (i)  such   actual  or   alleged
                  infringement  by  the  Acquired  Network   Facilities  on  the
                  Effective  Date or (ii) an act or  omission  of  Telerate or a
                  Telerate  Subsidiary  or a vendor or customer of Telerate or a
                  Telerate  Subsidiary  or (iii)  equipment or


                                       18
<PAGE>


                  software  used by Telerate  and not provided by SAVVIS or (iv)
                  services or equipment provided by or on behalf of Bridge under
                  the Technical Services Agreement. Telerate shall notify SAVVIS
                  promptly  in  writing  of any such  claim  or suit  and  shall
                  cooperate  with SAVVIS in a reasonable  way to facilitate  the
                  settlement  or  defense  thereof.  SAVVIS  further  agrees  to
                  indemnify and hold Telerate  harmless from and against any and
                  all liabilities and damages (whether incurred as the result of
                  a judicial decree or a settlement), and the costs and expenses
                  associated  with any claim or action of the type identified in
                  this Section (including reasonable attorneys' fees).

         16.2.    If,  as a  consequence  of a  claim  or  action  of  the  kind
                  described in Section 16.1, SAVVIS' or Telerate's use of all or
                  part of any Network is enjoined,  SAVVIS shall,  at its option
                  and  expense,  either:  (a) procure for  Telerate the right to
                  continue using the affected  Network;  (b) modify such Network
                  so  that   they  are   non-infringing,   provided   that  such
                  modification  does not affect the  intended use of the Network
                  as contemplated  hereunder. If SAVVIS does not take any of the
                  actions  described  in clauses (a) or (b),  then  Telerate may
                  terminate  the affected  portion of such  Network,  and SAVVIS
                  shall refund to Telerate any prepaid charges therefor.

         16.3.    Subject to Section 12,  Telerate  will defend,  indemnify  and
                  hold  harmless  SAVVIS  or  any of  its  directors,  officers,
                  employees  or assigns  from and against  all loss,  liability,
                  damage and  expense,  including  reasonable  attorneys'  fees,
                  caused by:

                  (a)      claims for  libel,  slander,  invasion  of privacy or
                           infringement   of  copyright,   and  invasion  and/or
                           alteration  of private  records or data  arising from
                           any  information,  data or messages  transmitted over
                           the Networks by Telerate; and

                  (b)      claims for  infringement  of patents arising from the
                           use by Telerate of equipment and software,  apparatus
                           and systems not provided hereunder in connection with
                           the Networks; and

                  (c)      the violation of any representations,  warranties and
                           covenants made by Bridge in this Agreement.

         16.4.    Subject to Section 12, SAVVIS will defend,  indemnify and hold
                  harmless Telerate or any of its directors, officers, employees
                  or assigns  from and against all loss,  liability,  damage and
                  expense, including reasonable attorneys' fees, caused by:

                  (a)      claims for  infringement  of patents arising from the
                           use by SAVVIS of equipment  and  software,  apparatus
                           and  systems  not  provided  by SAVVIS  hereunder  in
                           connection with the Networks (other than any Acquired

17.      DISPUTES

         17.1.    Except  as   expressly   provided  in  Schedule  4.1  of  this
                  Agreement, the resolution of any and all disputes arising from
                  or  in  connection  with  this  Agreement,  whether  based  on
                  contract, tort, statute or otherwise,  including disputes over
                  arbitrability  and disputes in connection with claims by third
                  persons  ("DISPUTES")  shall be  exclusively  governed  by and
                  settled in accordance  with the provisions of this Section 17.
                  The  foregoing   shall  not  preclude   recourse  to  judicial
                  proceedings to obtain injunctive, emergency or other equitable
                  relief to enforce the provisions of this Agreement,  including
                  specific  performance,  and  to  decide  such  issues  as  are
                  required to be resolved in  determining  whether to grant such
                  relief. Resolution of Disputes with respect to claims by third
                  persons shall be deferred until any judicial  proceedings with
                  respect thereto are concluded.

         17.2.    The parties  hereby  agree to submit all  Disputes to rules of
                  arbitration of the American  Arbitration  Association  and the
                  Missouri  Uniform  Arbitration  Act (the  "RULES")  under  the
                  following  provisions,  which shall be final and binding  upon
                  the  parties,  their  successors  and  assigns,  and  that the
                  following  provisions  constitute a binding arbitration clause
                  under applicable law. Either party may serve process or notice
                  on the other in any  arbitration  or  litigation in accordance
                  with the notice  provisions  hereof.  The parties agree not to
                  disclose any information  regarding any Dispute or the conduct
                  of any arbitration hereunder,  including the existence of such
                  Dispute or such  arbitration,  to any  person or entity  other
                  than such employees or representatives of such party as have a
                  need to know.

         17.3.    Either party may commence proceedings hereunder by delivery of
                  written  notice  providing  a  reasonable  description  of the
                  Dispute to the other,  including a reference to this provision
                  (the "DISPUTE NOTICE").  Either party may initiate arbitration
                  of  a  Dispute  by   delivery  of  a  demand   therefor   (the
                  "ARBITRATION  DEMAND")  to the other  party not sooner than 60
                  calendar days after the date of delivery of the Dispute Notice
                  but at any time thereafter. The arbitration shall be conducted
                  in St. Louis, Missouri.

         17.4.    The arbitration  shall be conducted by three  arbitrators (the
                  "ARBITRATORS"), one of whom shall be selected by Telerate, one
                  by  SAVVIS,  and the third by  agreement  of the other two not
                  later than 10 days  after  appointment  of the first two,  or,
                  failing such agreement, appointed pursuant to the Rules. If an
                  Arbitrator  becomes  unable to  serve,  a  successor  shall be
                  selected  or  appointed  in  the  same  manner  in  which  the
                  predecessor Arbitrator was appointed.

         17.5.    The arbitration shall be conducted pursuant to such procedures
                  as the parties may agree or, in the absence of or failing such
                  agreement,   pursuant  to  the  Rules.

                  Notwithstanding the foregoing, each party shall have the right
                  to inspect  the books and  records of the other party that are
                  reasonably  related  to the  Dispute,  and  each  party  shall
                  provide to the other,  reasonably  in advance of any  hearing,
                  copies of all documents which such party intends to present in
                  such  hearing  and the names and  addresses  of all  witnesses
                  whose testimony such party intends to present in such hearing.

         17.6.    All hearings shall be conducted on an expedited schedule,  and
                  all proceedings shall be confidential. Either party may at its
                  expense make a stenographic record thereof.

         17.7.    The Arbitrators  shall complete all hearings not later than 90
                  calendar days after the Arbitrators' selection or appointment,
                  and shall make a final award not later than 30  calendar  days
                  thereafter.  The  Arbitrators  shall  apportion  all costs and
                  expenses of the Arbitration,  including the Arbitrators'  fees
                  and  expenses  of experts  ("ARBITRATION  COSTS")  between the
                  prevailing and non-prevailing  parties as the Arbitrators deem
                  fair and reasonable. In circumstances where a Dispute has been
                  asserted or defended  against on grounds that the  Arbitrators
                  deem manifestly  unreasonable,  the Arbitrators may assess all
                  Arbitration  Costs  against the  non-prevailing  party and may
                  include in the award the prevailing  party's  attorneys'  fees
                  and expenses in connection with any and all proceedings  under
                  this Section 17.

         17.8.    Either party may assert appropriate  statutes of limitation as
                  a defense in  arbitration;  provided,  that upon delivery of a
                  Dispute  Notice  any  such  statute  shall be  tolled  pending
                  resolution hereunder.

         17.9.    Pending the resolution of any dispute or  controversy  arising
                  under this  Agreement,  the parties shall  continue to perform
                  their respective obligations  hereunder,  and SAVVIS shall not
                  discontinue,  disconnect  or in any  other  fashion  cease  to
                  provide  all or any  substantial  portion of the  Networks  to
                  Telerate  unless  otherwise  directed by Bridge.  This Section
                  shall not apply where (a)  Telerate  is in default  under this
                  Agreement  or (b)  the  dispute  or  controversy  between  the
                  parties  relates to harm to the Networks  allegedly  caused by
                  Telerate and Telerate  does not  immediately  cease and desist
                  from the activity giving rise to the dispute or controversy.

18.      FORCE MAJEURE

         18.1.    In no event shall  either party be liable to the other for any
                  failure  to  perform  hereunder  that  is due to  war,  riots,
                  embargoes, strikes or other concerted acts of workers (whether
                  of a party  hereto or of  others),  casualties,  accidents  or
                  other   causes  to  the  extent  that  such  failure  and  the
                  consequences  thereof  are  reasonably  beyond the control and
                  without the fault or negligence of the party claiming  excuse.
                  Each party shall, with the cooperation of the other party, use
                  reasonable  efforts to  mitigate  the extent of any failure to
                  perform and the adverse consequences thereof.

                                       21

         18.2.    If SAVVIS cannot promptly provide a suitable  temporary SAVVIS
                  alternative  to  all  or  part  of a  Network  subject  to  an
                  interruption  in  connection  with  the  existence  of a force
                  majeure condition,  Telerate may, at its option and at its own
                  cost, contract with one or more third parties for the affected
                  portion of the Network for the shortest commercially available
                  period likely to cover the reasonably expected duration of the
                  interruption,  and  may  suspend  SAVVIS'  provision  of  such
                  affected  portion  for such  period.  SAVVIS  shall not charge
                  Telerate for the affected  portion thus  suspended  during the
                  period of  suspension.  SAVVIS shall  resume  provision of the
                  suspended  portion  of  the  Network  upon  the  later  of the
                  termination  or  expiration  of  Telerate's   legally  binding
                  commitments under contracts with third parties for alternative
                  services  or the  cessation  or remedy  of the  force  majeure
                  condition.

         18.3.    In the event that a force majeure condition shall continue for
                  more than 60 days, Telerate may cancel the affected portion of
                  the Network with no further liability to SAVVIS other than for
                  obligations  incurred  with respect to such  affected  portion
                  prior to the occurrence of the force majeure condition.

         18.4.    The consequences  arising from existence and continuation of a
                  force majeure  condition,  including  without  limitation  any
                  interruption  of the  Networks and the exercise by Telerate of
                  its  rights  under  this  Section  18,  shall be deemed not to
                  constitute   a  breach   by   either   party   hereto  of  any
                  representations,  warranties or covenants  hereunder and shall
                  not be grounds  for the  exercise of any  remedies  under this
                  Agreement, including without limitation remedies under Section
                  2.2 or Section 7, other than those  specified  in this Section
                  18.

19.      GENERAL PROVISIONS

         19.1.    NO THIRD-PARTY BENEFICIARIES.  This Agreement shall not confer
                  any rights or  remedies  upon any person or entity  other than
                  the  parties and their  respective  successors  and  permitted

                  referred to herein)  constitutes the entire agreement  between
                  the  parties   and   supersedes   any  prior   understandings,
                  agreements,  or  representations  by or between  the  parties,
                  written or oral,  to the extent they related in any way to the
                  subject matter hereof.

         19.3.    SUCCESSION AND  ASSIGNMENT.  This  Agreement  shall be binding
                  upon and inure to the benefit of the parties  named herein and
                  their respective  successors and permitted  assigns.  No party
                  may  assign  either  this  Agreement  or any  of  its  rights,
                  interests,  or obligations hereunder without the prior written
                  approval  of the  other  party,  which  consent  shall  not be
                  unreasonably withheld.

         19.4.    COUNTERPARTS.  This  Agreement  may be executed in one or more
                  counterparts,  each of which shall be deemed an  original  but
                  all of  which  together  will  constitute  one  and  the  same
                  instrument.

         2.2      Each Network  shall be  operated,  managed and  maintained  by
                  SAVVIS.  SAVVIS  may,  but  shall  not be  obligated  to,  use
                  facilities   of  SAVVIS  other  than  the   Acquired   Network
                  Facilities  to  provide  all  or  any  part  of  any  Network.
                  Beginning on the first  anniversary  of the Effective Date and
                  thereafter,  each  Network  shall  be  operated,  managed  and
                  maintained  by SAVVIS  according  to the  Quality  of  Service
                  Standards  set forth in Schedule 2.2 hereof,  and SAVVIS shall
                  be responsible  for monitoring the performance of the Networks
                  with  respect to the  Quality of Service  Standards  and shall
                  provide Customer with monthly reports of such performance.  If
                  the Quality of Service Standards are not met with respect to a
                  particular  Installation Site in any month,  Customer shall be
                  entitled to receive,  upon written  request by Customer within
                  30 days of its  receipt  of the  performance  report  for such
                  Installation  Site for such month,  a credit in the amount set
                  forth on Schedule  2.2  attached  hereto (or, in the case of a
                  Distributor  Country,  as set  forth  on  Schedule  2.2 to the
                  Network Services  Agreement),  which amount shall be deemed to
                  be one month's charges  applicable to such  Installation  Site
                  under this  Agreement  with  respect to such month;  provided,
                  however, that Customer shall not be entitled to such credit to
                  the extent  that the  failure  to meet the  Quality of Service
                  Standards with respect to such Installation Site is due to (i)
                  an act or  omission  of  Customer  or a vendor or  customer of
                  Customer or (ii)  equipment  or software  used by Customer and
                  not  provided  by  SAVVIS.  Not more  than one  credit  of one
                  month's  charges shall be given for a particular  Installation
                  Site for a particular  month. The Quality of Service Standards
                  shall not apply to the provision of Local Access Facilities in
                  countries  in which the  products and services of Telerate and
                  Telerate   Subsidiaries  are  provided   through   third-party
                  distributors.  For all purposes of this  Agreement,  including
                  without limitation the determination of an Event of Default by
                  SAVVIS,  the  Quality of  Service  Standards  applicable  to a
                  particular  Installation  Site in any month shall be deemed to
                  have been met unless  Customer,  within 30 days of its receipt
                  of the performance  report for such Installation Site for such
                  month,  requests  in writing a credit as set forth  above with
                  respect to such Installation Site for such month.

         2.3      [Intentionally omitted.]

         2.4      In providing  Additional Network Facilities,  SAVVIS agrees to
                  use its best  efforts  to  expedite  the  provisioning  of the
                  circuits  for  such  Additional  Network  Facilities  in those
                  instances in which SAVVIS is responsible for provisioning such
                  circuits,  and to use its best efforts to avoid single  points
                  of  failure  in the  engineering  design  of  such  Additional
                  Network  Facilities,  consistent  with the level of redundancy
                  specified in the applicable Addendum.

         2.5      Throughout  the term of this  Agreement,  SAVVIS shall use its
                  reasonable  best  efforts to continue to meet the  requests of
                  Customer to enhance the total capacity,

                                       29
<PAGE>

                  geographic  extension and performance quality of the Networks,
                  and to maintain its research and development effort at a level
                  appropriate  to sustain  the ability of Customer to compete on
                  the basis of the quality of the Networks.

3.        RATES AND CHARGES

         3.1      Customer  shall pay SAVVIS for the Networks using the Acquired
                  Network Facilities and Additional Network Facilities according
                  to the rates and  charges  set  forth in  Schedule  3.1 of the
                  Network Services Agreement.

         3.2      The parties  recognize that certain  savings might be obtained
                  by consolidating the multiple Local Access Facilities that are
                  provided at such building  locations on the Effective Date. In
                  the event that SAVVIS  consolidates  the multiple Local Access
                  Facilities  at one or  more  of such  building  locations  and
                  obtains  cost  savings as a result  thereof,  the parties will
                  mutually agree within 30 days following such  consolidation on
                  the manner in which such savings shall be shared as follows:

                           (a)      between   SAVVIS  and   Customer,   if  only
                                    Customer  uses  those   consolidated   Local
                                    Access Facilities; or

                           (b)      between  SAVVIS,  Customer and the Affiliate
                                    of [Telerate Parent]/[Bridge Parent] that is
                                    a  party  to the  Local  [Telerate]/[Bridge]
                                    Network Services Agreement, if both Customer
                                    and such  Affiliate  use those  consolidated
                                    Local Access Facilities.

         3.3      For  any  Installation  Site  to  which  SAVVIS  is  providing
                  services    both   under   this    Agreement   and   a   Local
                  [Telerate]/[Bridge]  Network Services Agreement, the rates and
                  charges  applicable  to  such  Installation  Site  under  this
                  Agreement  shall be  one-half  of the rates and  charges  that
                  would otherwise be applicable to such  Installation Site under
                  this Agreement.

4.       PROVISION OF TAIL CIRCUITS

         4.1    SAVVIS  shall use its  reasonable  efforts  to  provide a Tail
                  Circuit to Customer  by  contracting  with the Local  Exchange
                  Carrier  for access to the Tail  Circuit  and causing the Tail
                  Circuit to be operated,  managed,  and maintained as necessary
                  to  provide  access  thereto  to  Customer.  SAVVIS  does  not
                  guarantee  or warrant the  performance  of the Tail Circuit or
                  the   performance  by  the  Local  Exchange   Carrier  of  its
                  obligations  under any contract  between  SAVVIS and the Local
                  Exchange   Carrier,   applicable  laws  and  regulations,   or
                  standards of the industry.

         4.2      Customer  shall not use the Tail Circuit in any way that might
                  cause SAVVIS to violate the terms and  conditions  under which
                  access to the Tail  Circuit is provided by the Local  Exchange
                  Carrier,  whether such terms and  conditions  be  contractual,
                  regulatory, or other.

                                       30
<PAGE>

         4.3      Customer shall be responsible for only that portion of SAVVIS'
                  costs  attributable to Customer's own access to and use of the
                  Tail Circuit.  In the event that SAVVIS provides access to any
                  third  party or parties,  Customer  and SAVVIS will follow the
                  procedure set forth in Section 1.2 above in order to establish
                  a mutually  agreed upon method or formula for  determining the
                  amount to be charged  to  Customer,  generally  based on a pro
                  rata allocation of SAVVIS' total costs among all its customers
                  and other relevant  considerations  and/or fair and reasonable
                  adjustments in light of the circumstances at that time.

5.       INVOICES

         5.1      The amounts due to SAVVIS from Customer for the  installation,
                  operation, management and maintenance of the Networks shall be
                  billed  monthly  in  advance.  All items on  invoices  not the
                  subject of a bona fide dispute shall be payable by Customer in
                  legal currency of [jurisdiction]  within 30 days from the date
                  of receipt of the  invoice.  All  amounts  not in dispute  are
                  subject to interest  charges of 1-1/2 percent that will accrue
                  daily on all  amounts  not paid  within 30 days of the date of
                  receipt of the invoice.

         5.2      At any time and from time to time,  Customer  may,  by written
                  notice to SAVVIS,  have one or more Installation Sites removed
                  from  the  Networks.  Each  monthly  invoice  from  SAVVIS  to
                  Customer  shall  reflect a reduction in the amount  charged to
                  Customer for the Networks  resulting  from any such removal of
                  Installation  Sites.  In the  case  of any  Installation  Site
                  removed from the Acquired Network  Facilities,  such reduction
                  shall be the sum of:

                  (a)      the  actual  cost  of  the  Local  Access  Facilities
                           connecting  the Acquired  Network  Facilities to such
                           Installation  Site,  effective  as of  such  time  as
                           SAVVIS is no longer required to pay such costs, and

                  (b)      the amounts set forth on Schedule  5.2 of the Network
                           Services  Agreement,  which  are  deemed  to  be  one
                           month's charges  applicable to such Installation Site
                           under  this  Agreement  with  respect  to such  month
                           during the first  Agreement  Year,  according  to the
                           geographic  location  and  connection  speed  at such
                           Installation Site,  effective as of such time as such
                           Installation Site is disconnected from the Networks.

         5.3      Customer shall pay any sales,  use,  federal excise,  utility,
                  gross receipts,  state and local  surcharges,  value added and
                  similar  taxes,  charges or levies  lawfully  levied by a duly
                  constituted taxing authority against or upon the Networks.  In
                  the   alternative,   Customer  shall  provide  SAVVIS  with  a
                  certificate evidencing Customer's exemption from payment of or
                  liability for such taxes. All other taxes,  charges or levies,
                  including  any ad valorem,  income,  franchise,  privilege  or
                  occupation taxes of SAVVIS shall be paid by SAVVIS.

         5.4      Bona fide disputes  concerning  invoices  shall be referred to
                  the parties' respective  representatives who are authorized to
                  resolve such matters. Any amount to which Customer is entitled
                  as a result of the  resolution  of a billing  dispute shall be
                  credited promptly to Customer's  account.  Any amount to which
                  SAVVIS is entitled as a result of the  resolution of a billing
                  dispute shall be paid promptly to SAVVIS.

         5.5      Against  the amounts  owed by  Customer  to SAVVIS  under this
                  Agreement, Customer shall have the right to offset any amounts
                  owed by SAVVIS to Customer under this Agreement, or otherwise,
                  including without limitation any amounts paid by Bridge Parent
                  on behalf  of  SAVVIS  under  guarantees  by Bridge  Parent of
                  obligations of SAVVIS.

6.       TERM AND EXTENSIONS

         6.1      This Agreement  shall commence on the Effective Date and shall
                  continue in full force and effect for the Initial  Term unless
                  terminated  or  extended  in  accordance  with the  provisions
                  hereof.

         6.2      The term of this Agreement may be extended by Customer for one
                  additional  five-year  period by giving SAVVIS  written notice
                  not less than one year before the scheduled  expiration of the
                  Initial Term.

         6.3      Upon the  termination of this Agreement in accordance with its
                  scheduled  expiration  or by  Customer  pursuant to Section 7,
                  SAVVIS will  continue to provide  the  Networks in  accordance
                  with the terms and  conditions  herein  (excluding the Minimum
                  Annual  Commitment) for a period of up to five years after the
                  effective  date  of  termination  (the  "TRANSITION  PERIOD").
                  During the  Transition  Period,  Customer shall pay SAVVIS for
                  the  use of  the  Networks  at  the  rates  in  effect  at the
                  effective date of termination.  If Customer has not completely
                  transitioned from its use of the Networks after the Transition
                  Period,  SAVVIS  will  provide the  Networks  at SAVVIS'  then
                  current list rates.  SAVVIS and its successor  will  cooperate
                  with  Customer  until  Customer  has  completely  migrated  to
                  another provider.

         6.4      The above  provisions of this Section 6  notwithstanding,  the
                  term of this  Agreement,  including  the Initial  Term and any
                  extension  provided  under  Section  6.2,  and the  Transition
                  Period  shall not  extend  beyond  the term or the  transition
                  period of the Network Services Agreement.

7.       TERMINATION BY CUSTOMER

         7.1      An "EVENT OF DEFAULT BY SAVVIS" shall be deemed to occur if:

                  (a)      SAVVIS has failed to a material  degree to perform or
                           comply   with   or   has    violated   any   material
                           representation,    warranty,   term,   condition   or

                                       32
<PAGE>


                           obligation of SAVVIS under this Agreement, and SAVVIS
                           has failed to cure such failure or  violation  within
                           60 days after receiving notice thereof from Customer;
                           or

                  (b)      SAVVIS   becomes  the  subject  of  a  voluntary   or
                           involuntary bankruptcy, insolvency, reorganization or
                           liquidation  proceeding,  makes an assignment for the
                           benefit  of  creditors,  or  admits  in  writing  its
                           inability to pay debts when due; or

                  (c)      an Event of Default by SAVVIS  occurs under the Local
                           [Telerate]/[Bridge]  Network  Services  Agreement  or
                           SAVVIS Communications defaults under the terms of the
                           Network Services Agreement.

         7.2      Customer  shall have the right to  terminate  this  Agreement,
                  with no liability  to SAVVIS other than for charges  (less any
                  applicable  credits) for the Networks  provided  prior to such
                  termination, if:

                  (a)      Customer  provides  written notice to SAVVIS,  at any
                           time  after the ninth  anniversary  of the  Effective
                           Date,  of  Customer's   intent  to  terminate,   such
                           termination  to be  effective  not less than one year
                           following the date of such notice; or

                  (b)      Customer  provides  10  days  written  notice  of its
                           intent to  terminate  in the  event  that an Event of
                           Default by SAVVIS occurs.

         7.3      For  purposes  of Section  7.1(a),  if the  Quality of Service
                  Standards   are  not  met  with   respect   to  a   particular
                  Installation Site in any month, SAVVIS shall be deemed to have
                  cured such  failure  within 60 days if the  Quality of Service
                  Standards  are met with respect to such  Installation  Site in
                  the following  month.  The parties  acknowledge and agree that
                  the failure of the Quality of Service Standards to be met with
                  respect  to one or  more  Installation  Sites  in one or  more
                  months may, but does not necessarily,  constitute a failure by
                  SAVVIS to a material  degree to  perform  or comply  with or a
                  violation to a material degree of any material representation,
                  warranty,  term,  condition or obligation of SAVVIS under this
                  Agreement.

         7.4      As  provided  in  Section   2.2,  for  all  purposes  of  this
                  Agreement,  including without  limitation the determination of
                  an Event of Default by SAVVIS under this Section,  the Quality
                  of Service Standards  applicable to a particular  Installation
                  Site in any month  shall be  deemed  to have  been met  unless
                  Customer,  within 30 days of its  receipt  of the  performance
                  report for such Installation Site for such month,  requests in
                  writing a credit as set forth in Section  2.2 with  respect to
                  such Installation Site for such month.

8.       TERMINATION BY SAVVIS

                  (a)      Customer  has failed to pay any  invoice  that is not
                           the subject of a bona fide dispute  within 60 days of
                           the date on which such  payment is due and SAVVIS has
                           provided   Customer  with  written  notice   thereof,
                           provided that  Customer  shall have a further 30 days
                           from the time it receives  such notice from SAVVIS of
                           nonpayment to cure any such default;

                  (b)      SAVVIS  provides 10 days written notice of its intent
                           to terminate in the event that Customer has failed to
                           perform or comply with or has  violated  any material
                           representation,    warranty,   term,   condition   or
                           obligation  of  Customer  under this  Agreement,  and
                           Customer has failed to cure such failure or violation
                           within 60 days after  receiving  notice  thereof from
                           SAVVIS; or

                  (c)      Customer  becomes  the  subject  of  a  voluntary  or
                           involuntary bankruptcy, insolvency, reorganization or
                           liquidation  proceeding,  makes an assignment for the
                           benefit  of  creditors,  or  admits  in  writing  its
                           inability to pay debts when due; or

                  (d)      SAVVIS  becomes   entitled  to  terminate  the  Local
                           [Telerate]/[Bridge]  Network  Services  Agreement  or
                           SAVVIS  Communications  becomes entitled to terminate
                           the Network Services Agreement.

         8.2      Notwithstanding the provisions of Section 8.1(b) above, SAVVIS
                  shall not have the right to  terminate  this  Agreement  under
                  Section  8.1(b) solely for a failure by Customer to perform or
                  comply with, a violation  by Customer of, the  obligations  of
                  Customer under Section 15 (Confidentiality) of this Agreement,
                  without prejudice,  however, to such rights as SAVVIS may have
                  pursuant to such  Section  and to such rights and  remedies to
                  which  SAVVIS may be  entitled,  at law or in  equity,  as the
                  result of an actual or  threatened  breach by Customer of such
                  Section.

9.       ACCEPTANCE OF ADDITIONAL NETWORK FACILITIES

         9.1.     Upon the installation of Additional  Network Facilities at any
                  Installation  Site, SAVVIS shall conduct  appropriate tests to
                  establish that such Additional  Network  Facilities perform in
                  accordance  with  mutually  agreed  upon  acceptance  criteria
                  ("ACCEPTANCE  CRITERIA") set forth in the applicable  Addendum
                  entered  into  pursuant  to Section  2.4,  and shall  promptly
                  inform  Customer of such test  results.  If test  results show
                  that the  Additional  Network  Facilities  are  performing  in
                  accordance  with the  Acceptance  Criteria,  Customer shall be
                  deemed to accept  the  Additional  Network  Facilities  at the
                  Installation Site immediately.

<PAGE>


         9.2      If SAVVIS' tests  establish  that newly  installed  Additional
                  Network  Facilities at the Installation Site do not perform in
                  accordance with the mutually agreed upon Acceptance  Criteria,
                  then SAVVIS shall  immediately  and diligently  exert its best
                  efforts to bring the  Additional  Network  Facilities  at such
                  Installation  Site  into  compliance.  SAVVIS  shall  not bill
                  Customer  for  the  Additional   Network  Facilities  at  such
                  Installation  Site  until  the  test  results  show  that  the
                  Additional  Network  Facilities  are  performing in accordance
                  with the Acceptance Criteria.

        9.3       Upon repair or restoration of any part of the Networks, SAVVIS
                  shall conduct appropriate tests to establish that the Networks
                  perform in  accordance  with mutually  agreed upon  Acceptance
                  Criteria  and  shall  promptly  inform  Customer  of such test
                  results.

10.      RIGHTS AND OBLIGATIONS OF CUSTOMER

         10.1     SITE PREPARATION.  For the installation of Additional  Network
                  Facilities,  Customer shall,  at its own expense,  provide all
                  necessary preparations of each Installation Site in accordance
                  with  the  requirements  to be  mutually  agreed  upon  by the
                  parties and set forth in an Addendum hereto,  including inside
                  wiring,  demarcation  extension  and rack  mount  accessories.
                  Customer  shall  ensure that  Customer-provided  equipment  is
                  on-site  by the  scheduled  installation  date.  If  SAVVIS is
                  required to reschedule the  installation of  Customer-provided
                  equipment   because  it  is  not  on-site  by  the   scheduled
                  installation  date,  Customer  shall pay SAVVIS to  redispatch
                  installation personnel.

         10.2.    PROPER USE OF NETWORKS.

                  10.2.1.  Customer  shall use any equipment  provided by SAVVIS
                           in connection  with the Networks in  accordance  with
                           its  documentation,   which  documentation  shall  be
                           provided by SAVVIS at no  additional  charge.  Unless
                           otherwise  provided  herein,  upon the termination of
                           this Agreement Customer shall surrender to SAVVIS the
                           equipment  provided by SAVVIS, in good working order,
                           ordinary wear and tear excepted.

                  10.2.2.  Customer  shall be liable for damages to the Networks
                           caused by the negligence or willful acts or omissions
                           of   Customer's   officers,   employees,   agents  or
                           contractors,  for loss through  theft or vandalism of
                           the  Networks  at  the  Installation  Site,  and  for
                           damages  to  the  Networks   caused  by  the  use  of
                           equipment or supplies  not provided  hereunder or not
                           otherwise authorized by SAVVIS.

                  10.2.3.  Customer  shall  neither  permit nor assist others to
                           use the Networks for any purpose  other than that for
                           which  they  are  intended,  nor fail to  maintain  a
                           suitable  environment  specified  by  SAVVIS  in  the
                           applicable  schedule,  nor alter, tamper with, adjust
                           or  repair  the   Networks.   Any  such   alteration,
                           tampering,  adjustment  or repair by  Customer  shall
                           relieve

                                       35
<PAGE>

                  SAVVIS from any liability or obligation  hereunder  (including
                  any warranty or indemnity obligation) relating to the affected
                  Network,  and  Customer  shall be  liable  to  SAVVIS  for any
                  documented direct costs incurred by SAVVIS as a result of such
                  actions.

         10.3.    ABUSE OR FRAUDULENT  USE OF NETWORKS.  Customer  shall neither
                  permit  nor  assist  others to abuse or  fraudulently  use the
                  Networks,  or to use  the  Networks  for any  unauthorized  or
                  illegal purposes, including:

                  (a)      obtaining  or  attempting  to obtain  service  by any
                           fraudulent means or device to avoid payment; or

                  (b)      accessing,  altering or destroying any information of
                           another party by any fraudulent  means or device,  or
                           attempting to do so; or

                  (c)      using the Networks so as to interfere with the use of
                           the  SAVVIS  network  by other  SAVVIS  customers  or
                           authorized users or in violation of law or in support
                           of any unlawful act; or

                  (d)      using the  Networks for voice  communications  over a
                           private  network in  jurisdictions  where such use is
                           not allowed.

                  Notwithstanding  the  provisions of Section 8, upon the breach
                  of this Section 10.3 by Customer,  SAVVIS shall have the right
                  to terminate this Agreement immediately upon written notice to
                  Customer.

         10.4.    COVENANT NOT TO COMPETE.

                  10.4.1.  As  an  inducement  to  SAVVIS  to  enter  into  this
                           Agreement,  which Customer acknowledges is of benefit
                           to it,  and in  consideration  of  the  promises  and
                           representations   of  SAVVIS  under  this  Agreement,
                           Customer covenants and agrees that during the term of
                           this  Agreement  and  for  a  period  of  five  years
                           thereafter,   neither   Customer   nor   any  of  its
                           successors or assigns will,  directly or  indirectly,
                           engage in, or have any interest in any other  person,
                           firm,  corporation  or other  entity  engaged in, any
                           business activities anywhere in the world competitive
                           with  or  similar  or  related  to  the   packet-data
                           transport  network services  provided by SAVVIS under
                           this Agreement;  provided, however, that (i) Customer
                           shall be free to  continue to use the Call Assets and
                           the satellite  networks  currently  used by Customer,
                           until such Call  Assets or  satellite  networks  have
                           been  acquired by SAVVIS,  SAVVIS  Communications  or
                           Affiliates   of  SAVVIS   Communications,   and  (ii)
                           Customer shall be free to make passive investments in
                           securities of companies that provide network services
                           in competition  with SAVVIS which, in the case of any
                           such  security,  does not  constitute  more  than ten
                           percent (10%) of the total outstanding amount of such
                           security.

                  10.4.2.  If any court or  tribunal of  competent  jurisdiction
                           shall refuse to enforce one or more of the  covenants
                           in  this   Section   10.4   because  the  time  limit
                           applicable  thereto  is  deemed  unreasonable,  it is
                           expressly understood and agreed that such covenant or
                           covenants  shall not be void but that for the purpose
                           of such  proceedings  such time  limitation  shall be
                           deemed  to be  reduced  to the  extent  necessary  to
                           permit the enforcement of such covenant or covenants.

                  10.4.3.  If any court or  tribunal of  competent  jurisdiction
                           shall  refuse to enforce any or all of the  covenants
                           in this Section 10.4 because,  taken  together,  they
                           are more  extensive  (whether as to geographic  area,
                           scope of business or otherwise)  than is deemed to be
                           reasonable,  it is  expressly  understood  and agreed
                           between  the  parties  hereto  that such  covenant or
                           covenants  shall not be void but that for the purpose
                           of  such  proceedings  the   restrictions   contained
                           therein  (whether  as to  geographic  area,  scope of
                           business or otherwise)  shall be deemed to be reduced
                           to the extent  necessary to permit the enforcement of
                           such covenant or covenants.

                  10.4.4.  Customer  specifically  acknowledges  and agrees that
                           the foregoing  covenants are commercially  reasonable
                           and reasonably  necessary to protect the interests of
                           SAVVIS hereunder.  Customer hereby  acknowledges that
                           SAVVIS and its  successors  and  assigns  will suffer
                           irreparable  and  continuing  harm to the extent that
                           any of the  foregoing  covenants is breached and that
                           legal  remedies  would be  inadequate in the event of
                           any such breach.

11.      RIGHTS AND OBLIGATIONS OF SAVVIS

         11.1.    PROVISION OF THE NETWORKS.  SAVVIS shall operate, maintain and
                  manage  the  Networks  at the  Installation  Sites  using  the
                  Acquired Network  Facilities in accordance with the Quality of
                  Service Standards and other terms of this Agreement, including
                  all Addenda hereto.

         11.2.    REPRESENTATIONS AND WARRANTIES.

                  11.2.1.  [Intentionally omitted.]

                  11.2.2.  SAVVIS hereby  represents and warrants that the terms
                           hereof do not conflict in any respect whatsoever with
                           any   SAVVIS   tariff  on  file   with  the   Federal
                           Communications  Commission or other  regulatory body.
                           If, during the term of this  Agreement,  SAVVIS shall
                           file  a  contract   specific  tariff   governing  the
                           Networks or any portion  thereof,  such tariff filing
                           shall be consistent in all respects with the terms of
                           this  Agreement,  and SAVVIS  shall give  Customer 10
                           days advance  written  notice of making such a tariff
                           filing  and of filing  any  subsequent  modifications
                           thereto.

                                       37
<PAGE>

                  11.2.3.  THE  FOREGOING  WARRANTIES  ARE IN LIEU OF ALL  OTHER
                           WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED
                           WARRANTIES  OF  MERCHANTABILITY  AND  FITNESS  FOR  A
                           PARTICULAR PURPOSE.

         11.3.    SAVVIS acknowledges that the occurrence of Event of Default by
                  SAVVIS,  arising  from either (i) a failure of the Networks to
                  meet  Quality  of  Service  Standards  or (ii) a total loss to
                  Customer of the use of the Networks,  could cause  irreparable
                  harm to  Customer,  the  amount of which may be  difficult  to
                  determine,  thus  potentially  making  any remedy at law or in
                  damages inadequate.  SAVVIS,  therefore,  agrees that Customer
                  shall  have  the  right to  apply  to any  court of  competent
                  jurisdiction  for injunctive  relief upon the occurrence of an
                  Event of  Default  by  SAVVIS  or the  occurrence  of an event
                  which, with the passage of time or the giving of notice, could
                  become  an  Event  of  Default  by  SAVVIS  and for any  other
                  appropriate  relief.  This right  shall be in  addition to any
                  other remedy  available  to Customer in law or equity.  SAVVIS
                  further  agrees  that,  upon  the  occurrence  of an  Event of
                  Default by SAVVIS, SAVVIS shall pay to Customer, as liquidated
                  damages and not as a penalty, an amount equal to the lesser of
                  (a) the  aggregate  amounts  paid by Customer to SAVVIS  under
                  this Agreement  during the six months  preceding such Event of
                  Default by SAVVIS or (b) $50,000,000;  provided, however, that
                  Customer  may recover  liquidated  damages  under this Section
                  only for an Event of Default by SAVVIS  that  occurs (i) prior
                  to any Event of  Default  by  SAVVIS  for  which  Customer  or
                  [Bridge  Parent]/[Telerate  Parent] or any customer of [Bridge
                  Parent]/[Telerate Parent] has claimed liquidated damages under
                  this  Section  or under a Network  Services  Agreement  or any
                  Local [Telerate]/[Bridge]  Network Services Agreement, or (ii)
                  more than 36 months following the most recent Event of Default
                  by SAVVIS  for which  Customer  or  [Bridge  Parent]/[Telerate
                  Parent] or any customer of [Bridge  Parent]/[Telerate  Parent]
                  has claimed  liquidated  damages under this Section or under a
                  Network  Services  Agreement or any Local  [Telerate]/[Bridge]
                  Network Services Agreement.

12.      LIMITATIONS OF LIABILITY

         12.1.    Subject to Section 11.4,  neither party shall be liable to the
                  other  for  indirect,  incidental,  consequential,  exemplary,
                  reliance  or  special  damages,  including  damages  for  lost
                  profits, regardless of the form of action whether in contract,
                  indemnity,  warranty,  strict  liability  or  tort,  including
                  negligence  of any kind with  respect to the Networks or other
                  conduct under this Agreement.

         12.2.    Nothing  contained in this Section shall limit either  party's
                  liability  to  the  other  for  (a)  willful  or   intentional
                  misconduct, including fraud, or (b) injury or death, or damage
                  to  tangible  real  or  tangible   personal  property  or  the
                  environment,  when proximately caused by SAVVIS' or Customer's
                  negligence or that of their respective agents,  subcontractors
                  or  employees.  Nothing  contained in this

                                       38
<PAGE>

                  Section    shall   limit   SAVVIS'    intellectual    property
                  indemnification  obligations  under Section 16.1 or Customer's
                  indemnification  obligations  with  respect  to  a  breach  of
                  Section 10.3.

13.      EQUIPMENT AND SOFTWARE NOT PROVIDED BY SAVVIS

         13.1.    SAVVIS  shall  not  be  responsible   for  the   installation,
                  operation or maintenance of equipment or software not provided
                  by it under this  Agreement,  nor shall SAVVIS be  responsible
                  for the  transmission or reception of information by equipment
                  or software  not  provided by SAVVIS  hereunder.  In the event
                  that  Customer  uses  equipment  or software  not  provided by
                  SAVVIS  hereunder in a manner that impairs  Customer's  use of
                  the Networks,  Customer  shall not be excused from payment for
                  such use and SAVVIS shall not be  responsible  for any failure
                  of the  Networks  to meet the  Quality  of  Service  Standards
                  resulting  from  the  use of such  equipment  or  software  by
                  Customer.  Upon  notice  from  SAVVIS  that the  equipment  or
                  software  not  provided  by SAVVIS  under  this  Agreement  is
                  causing or is likely to cause hazard,  interference or service
                  obstruction,  Customer shall  eliminate the likelihood of such
                  hazard, interference or service obstruction.

         13.2.    Notwithstanding the foregoing,  SAVVIS shall, at no additional
                  charge, provide all interface  specifications for the Networks
                  reasonably  requested  by  Customer.  SAVVIS  shall,  upon the
                  receipt of appropriate  specifications  from Customer,  inform
                  Customer  of  the  compatibility  with  the  Networks  of  any
                  equipment  or  software  that  Customer  proposes  to  use  in
                  connection therewith,  the effects, if any, of the use of such
                  equipment    or   software   on   the    quality,    operating
                  characteristics  and  efficiency  of  the  Networks,  and  the
                  effects,   if  any,   of  the   Networks   on  the   operating
                  characteristics  and  efficiency  of  any  such  equipment  or
                  software.

14.      PROPRIETARY RIGHTS; LICENSE

         14.1.    SAVVIS   hereby  grants  to  Customer  a   non-exclusive   and
                  non-transferable  license to use all  programming and software
                  necessary  for Customer to use the  Networks.  Such license is
                  granted for the term of this Agreement for the sole purpose of
                  enabling Customer to use the Networks.

         14.2.    All title and property rights (including intellectual property
                  rights) to the Networks (including associated  programming and
                  software) are and shall remain with SAVVIS or the  third-party
                  providers  thereof to SAVVIS.  Customer  shall not  (except as
                  permitted by applicable law) attempt to examine,  copy, alter,
                  reverse  engineer,  decompile,  disassemble,  tamper  with  or
                  otherwise misuse the Networks, programming and software.

15.      CONFIDENTIALITY

         15.1.    During  the term of this  Agreement  and for a period  of five
                  years  from  the  date  of  its   expiration  or   termination
                  (including  all  extensions  thereof),  each  party  agrees to
                  maintain in strict  confidence all  Confidential  Information.
                  Neither  party shall,  without  prior  written  consent of the
                  other party,  use the other party's  Confidential  Information
                  for any purpose other than for the  performance  of its duties
                  and  obligations,  and the exercise of its rights,  under this
                  Agreement.   Each  party  shall  use,   and  shall  cause  all
                  authorized   recipients  of  the  other  party's  Confidential
                  Information  to use,  the same  degree of care to protect  the
                  other party's  Confidential  Information as it uses to protect
                  its own  Confidential  Information,  but in any event not less
                  than a reasonable degree of care.

         15.2.    Notwithstanding  Section  15.1,  either party may disclose the
                  Confidential  Information  of the  other  party  to:  (a)  its
                  employees  and the  employees,  directors  and officers of its
                  Affiliates  as  necessary  to implement  this  Agreement;  (b)
                  employees,  agents or  representatives  of the other party; or
                  (c) other persons (including counsel, consultants,  lessors or
                  managers of  facilities  or  equipment  used by such party) in
                  need of access to such  information for purposes  specifically
                  related  to  either   party's   responsibilities   under  this
                  Agreement,   provided  that  any  disclosure  of  Confidential
                  Information  under  clause  (c) shall be made only upon  prior
                  written  approval  of  the  other  party  and  subject  to the
                  appropriate  assurances that the recipient of such information
                  shall hold it in strict confidence.

         15.3.    Upon the  request of the party  having  proprietary  rights to
                  Confidential  Information,  the  party in  possession  of such
                  information  shall  promptly  return it (including any copies,
                  extracts and  summaries  thereof,  in whatever form and medium
                  recorded) to the  requesting  party or, with the other party's
                  written  consent,  shall  promptly  destroy it and provide the
                  other party with written certification of such destruction.

         15.4.    Either party may request in writing that the other party waive
                  all or any portion of the requesting party's  responsibilities
                  relative to the other party's Confidential  Information.  Such
                  waiver request shall identify the affected information and the
                  nature of the proposed  waiver.  The  recipient of the request
                  shall respond within a reasonable  time and, if it determines,
                  in its sole discretion, to grant the requested waiver, it will
                  do so in writing over the signature of an employee  authorized
                  to grant such request.

         15.5.    Customer  and  SAVVIS   acknowledge  that  any  disclosure  or
                  misappropriation  of Confidential  Information in violation of
                  this  Agreement  could cause  irreparable  harm, the amount of
                  which may be difficult to determine,  thus potentially  making
                  any  remedy  at  law or in  damages  inadequate.  Each  party,
                  therefore, agrees that the other party shall have the right to
                  apply to any  court  of  competent  jurisdiction

                                       40
<PAGE>


                  for an order  restraining  any breach or threatened  breach of
                  this Section and for any other appropriate  relief. This right
                  shall be in addition to any other  remedy  available in law or
                  equity.

         15.6.    A party requested or ordered by a court or other  governmental
                  authority  of  competent   jurisdiction  to  disclose  another
                  party's Confidential  Information shall notify the other party
                  in  advance  of any such  disclosure  and,  absent  the  other
                  party's  consent to such  disclosure,  use its best efforts to
                  resist,  and to assist  the  other  party in  resisting,  such
                  disclosure.  A party providing  another  party's  Confidential
                  Information to a court or other  governmental  authority shall
                  use  its  best  efforts  to  obtain  a  protective   order  or
                  comparable  assurance  that the  Confidential  Information  so
                  provided will be held in confidence and not further  disclosed
                  to any other person, absent the owner's prior consent.

         15.7.    The  provisions  of  Section  15.1  above  shall  not apply to
                  reasonably  necessary  disclosures  in or in  connection  with
                  filings  under any  securities  laws,  regulatory  filings  or
                  proceedings,  financial  disclosures  which in the good  faith
                  judgment  of  the  disclosing   party  are  required  by  law,
                  disclosures   required  by  court  or  tribunal  or  competent
                  jurisdiction,  or disclosures that may be reasonably necessary
                  in connection  with the sale of securities or the  performance
                  or  enforcement  of this  Agreement or any of the  obligations
                  hereof;  provided,  however, that if the receiving party would
                  otherwise  be required  to refer to or describe  any aspect of
                  this  Agreement  in any of the  preceding  circumstances,  the
                  receiving party shall use its reasonable  efforts to take such
                  steps as are available  under such  circumstances  (such as by
                  providing a summary or  synopsis) to avoid  disclosure  of the
                  financial    terms   and   conditions   of   this   Agreement.
                  Notwithstanding  any  provisions  of  this  Agreement  to  the
                  contrary,  either party may disclose the terms and  conditions
                  of this  Agreement  in the  course of a due  diligence  review
                  performed in connection  with  prospective  debt  financing or
                  equity  investment by, or a sale to, a third party, so long as
                  the persons  conducting such due diligence  review have agreed
                  to maintain the  confidentiality of such disclosure and not to
                  use such  disclosure  for any purpose other such due diligence
                  review.

16.      INDEMNIFICATIONS

         16.1.    SAVVIS shall defend,  settle,  or otherwise  manage at its own
                  cost and expense any claim or action  against  Customer or any
                  of its directors, officers, employees or assigns for actual or
                  alleged infringement by the Networks of any patent, copyright,
                  trademark,  trade secret or similar  proprietary  right of any
                  third party,  except to the extent that such actual or alleged
                  infringement   arises   from  (i)  such   actual  or   alleged
                  infringement  by  the  Acquired  Network   Facilities  on  the
                  Effective  Date or (ii) an act or  omission  of  Customer or a
                  vendor or customer of Customer or (iii)  equipment or software
                  used by Customer  and not provided by SAVVIS.  Customer  shall
                  notify  SAVVIS  promptly  in writing of any such claim or suit
                  and  shall  cooperate  with  SAVVIS  in a  reasonable  way  to
                  facilitate the

                                       41
<PAGE>

                  settlement  or  defense  thereof.  SAVVIS  further  agrees  to
                  indemnify and hold Customer  harmless from and against any and
                  all liabilities and damages (whether incurred as the result of
                  a judicial decree or a settlement), and the costs and expenses
                  associated  with any claim or action of the type identified in
                  this Section (including reasonable attorneys' fees).

         16.2.    If,  as a  consequence  of a  claim  or  action  of  the  kind
                  described in Section 16.1, SAVVIS' or Customer's use of all or
                  part of any Network is enjoined,  SAVVIS shall,  at its option
                  and  expense,  either:  (a) procure for  Customer the right to
                  continue using the affected  Network;  (b) modify such Network
                  so  that   they  are   non-infringing,   provided   that  such
                  modification  does not affect the  intended use of the Network
                  as contemplated  hereunder. If SAVVIS does not take any of the
                  actions  described  in clauses (a) or (b),  then  Customer may
                  terminate  the affected  portion of such  Network,  and SAVVIS
                  shall refund to Customer any prepaid charges therefor.

         16.3.    Subject to Section 12,  Customer  will defend,  indemnify  and
                  hold  harmless  SAVVIS  or  any of  its  directors,  officers,
                  employees  or assigns  from and against  all loss,  liability,
                  damage and  expense,  including  reasonable  attorneys'  fees,
                  caused by:

                  (a)      claims for  libel,  slander,  invasion  of privacy or
                           infringement   of  copyright,   and  invasion  and/or
                           alteration  of private  records or data  arising from
                           any  information,  data or messages  transmitted over
                           the Networks by Customer;

                  (b)      claims for  infringement  of patents arising from the
                           use by Customer of equipment and software,  apparatus
                           and systems not provided hereunder in connection with
                           the Networks; and

                  (c)      the violation of any representations,  warranties and
                           covenants made by Customer in this Agreement.

16.4.             Subject to Section 12, SAVVIS will defend,  indemnify and hold
                  harmless Customer or any of its directors, officers, employees
                  or assigns  from and against all loss,  liability,  damage and
                  expense, including reasonable attorneys' fees, caused by:

                  (a)      claims for  infringement  of patents arising from the
                           use by SAVVIS of equipment  and  software,  apparatus
                           and  systems  not  provided  by SAVVIS  hereunder  in
                           connection with the Networks (other than any Acquired
                           Network Facilities); and

                  (b)      the violation of any representations,  warranties and
                           covenants made by SAVVIS in this Agreement.

17.      DISPUTES

         17.1.    Except  as   expressly   provided  in  Schedule  4.1  of  this
                  Agreement, the resolution of any and all disputes arising from
                  or  in  connection  with  this  Agreement,  whether  based  on
                  contract, tort, statute or otherwise,  including disputes over
                  arbitrability  and disputes in connection with claims by third
                  persons  ("DISPUTES")  shall be  exclusively  governed  by and
                  settled in accordance  with the provisions of this Section 17.
                  The  foregoing   shall  not  preclude   recourse  to  judicial
                  proceedings to obtain injunctive, emergency or other equitable
                  relief to enforce the provisions of this Agreement,  including
                  specific  performance,  and  to  decide  such  issues  as  are
                  required to be resolved in  determining  whether to grant such
                  relief. Resolution of Disputes with respect to claims by third
                  persons shall be deferred until any judicial  proceedings with
                  respect thereto are concluded.

         17.2.    The parties  hereby  agree to submit all  Disputes to rules of
                  arbitration of the American  Arbitration  Association  and the
                  Missouri  Uniform  Arbitration  Act (the  "RULES")  under  the
                  following  provisions,  which shall be final and binding  upon
                  the  parties,  their  successors  and  assigns,  and  that the
                  following  provisions  constitute a binding arbitration clause
                  under applicable law. Either party may serve process or notice
                  on the other in any  arbitration  or  litigation in accordance
                  with the notice  provisions  hereof.  The parties agree not to
                  disclose any information  regarding any Dispute or the conduct
                  of any arbitration hereunder,  including the existence of such
                  Dispute or such  arbitration,  to any  person or entity  other
                  than such employees or representatives of such party as have a
                  need to know.

         17.3.    Either party may commence proceedings hereunder by delivery of
                  written  notice  providing  a  reasonable  description  of the
                  Dispute to the other,  including a reference to this provision
                  (the "DISPUTE NOTICE").  Either party may initiate arbitration
                  of  a  Dispute  by   delivery  of  a  demand   therefor   (the
                  "ARBITRATION  DEMAND")  to the other  party not sooner than 60
                  calendar days after the date of delivery of the Dispute Notice
                  but at any time thereafter. The arbitration shall be conducted
                  in St. Louis, Missouri.

         17.4.    The arbitration  shall be conducted by three  arbitrators (the
                  "ARBITRATORS"), one of whom shall be selected by Customer, one
                  by  SAVVIS,  and the third by  agreement  of the other two not
                  later than 10 days  after  appointment  of the first two,  or,
                  failing such agreement, appointed pursuant to the Rules. If an
                  Arbitrator  becomes  unable to  serve,  a  successor  shall be
                  selected  or  appointed  in  the  same  manner  in  which  the
                  predecessor Arbitrator was appointed.

         17.5.    The arbitration shall be conducted pursuant to such procedures
                  as the parties may agree or, in the absence of or failing such
                  agreement,   pursuant  to  the  Rules.   Notwithstanding   the
                  foregoing,  each party  shall  have the right to  inspect  the
                  books and  records  of the  other  party  that are  reasonably
                  related to the  Dispute,  and each party shall  provide to the
                  other,  reasonably  in advance of any  hearing,  copies of all

                                       43
<PAGE>


                  documents  which such party intends to present in such hearing
                  and the names and addresses of all witnesses  whose  testimony
                  such party intends to present in such hearing.

         17.6.    All hearings shall be conducted on an expedited schedule,  and
                  all proceedings shall be confidential. Either party may at its
                  expense make a stenographic record thereof.

         17.7.    The Arbitrators  shall complete all hearings not later than 90
                  calendar days after the Arbitrators' selection or appointment,
                  and shall make a final award not later than 30  calendar  days
                  thereafter.  The  Arbitrators  shall  apportion  all costs and
                  expenses of the Arbitration,  including the Arbitrators'  fees
                  and  expenses  of experts  ("ARBITRATION  COSTS")  between the
                  prevailing and non-prevailing  parties as the Arbitrators deem
                  fair and reasonable. In circumstances where a Dispute has been
                  asserted or defended  against on grounds that the  Arbitrators
                  deem manifestly  unreasonable,  the Arbitrators may assess all
                  Arbitration  Costs  against the  non-prevailing  party and may
                  include in the award the prevailing  party's  attorneys'  fees
                  and expenses in connection with any and all proceedings  under
                  this Section 17.

         17.8.    Either party may assert appropriate  statutes of limitation as
                  a defense in  arbitration;  provided,  that upon delivery of a
                  Dispute  Notice  any  such  statute  shall be  tolled  pending
                  resolution hereunder.

         17.9.    Pending the resolution of any dispute or  controversy  arising
                  under this  Agreement,  the parties shall  continue to perform
                  their respective obligations  hereunder,  and SAVVIS shall not
                  discontinue,  disconnect  or in any  other  fashion  cease  to
                  provide  all or any  substantial  portion of the  Networks  to
                  Customer unless otherwise  directed by Customer.  This Section
                  shall not apply where (a)  Customer  is in default  under this
                  Agreement  or (b)  the  dispute  or  controversy  between  the
                  parties  relates to harm to the Networks  allegedly  caused by
                  Customer and Customer  does not  immediately  cease and desist
                  from the activity giving rise to the dispute or controversy.

18.      FORCE MAJEURE

         18.1.    In no event shall  either party be liable to the other for any
                  failure  to  perform  hereunder  that  is due to  war,  riots,
                  embargoes, strikes or other concerted acts of workers (whether
                  of a party  hereto or of  others),  casualties,  accidents  or
                  other   causes  to  the  extent  that  such  failure  and  the
                  consequences  thereof  are  reasonably  beyond the control and
                  without the fault or negligence of the party claiming  excuse.
                  Each party shall, with the cooperation of the other party, use
                  reasonable  efforts to  mitigate  the extent of any failure to
                  perform and the adverse consequences thereof.

         18.2.    If SAVVIS cannot promptly provide a suitable  temporary SAVVIS
                  alternative  to  all  or  part  of a  Network  subject  to  an
                  interruption  in  connection  with  the  existence  of a force
                  majeure condition,  Customer may, at its option and at its own

                                       44
<PAGE>


                  cost, contract with one or more third parties for the affected
                  portion of the Network for the shortest commercially available
                  period likely to cover the reasonably expected duration of the
                  interruption,  and  may  suspend  SAVVIS'  provision  of  such
                  affected  portion  for such  period.  SAVVIS  shall not charge
                  Customer for the affected  portion thus  suspended  during the
                  period of  suspension.  SAVVIS shall  resume  provision of the
                  suspended  portion  of  the  Network  upon  the  later  of the
                  termination  or  expiration  of  Customer's   legally  binding
                  commitments under contracts with third parties for alternative
                  services  or the  cessation  or remedy  of the  force  majeure
                  condition.

         18.3.    In the event that a force majeure condition shall continue for
                  more than 60 days, Customer may cancel the affected portion of
                  the Network with no further liability to SAVVIS other than for
                  obligations  incurred  with respect to such  affected  portion
                  prior to the occurrence of the force majeure condition.

         18.4.    The consequences  arising from existence and continuation of a
                  force majeure  condition,  including  without  limitation  any
                  interruption  of the  Networks and the exercise by Customer of
                  its  rights  under  this  Section  18,  shall be deemed not to
                  constitute   a  breach   by   either   party   hereto  of  any
                  representations,  warranties or covenants  hereunder and shall
                  not be grounds  for the  exercise of any  remedies  under this
                  Agreement, including without limitation remedies under Section
                  2.2 or Section 7, other than those  specified  in this Section
                  18.

                  the  parties and their  respective  successors  and  permitted

                  interests,  or obligations hereunder without the prior written
                  approval  of the  other  party,  which  consent  shall  not be
                  unreasonably withheld.

         19.4.    COUNTERPARTS.  This  Agreement  may be executed in one or more
                  counterparts,  each of which shall be deemed an  original  but
                  all of  which  together  will  constitute  one  and  the  same
                  instrument.

1.       CONTRACT DOCUMENTS AND DEFINITIONS

         1.1.     This  Agreement  shall  consist  of  this  Technical  Services
                  Agreement  by and  between  SAVVIS and Bridge,  including  all
                  addenda to this Agreement entered into in the manner set forth
                  herein (each an "ADDENDUM" and  collectively  the  "ADDENDA").
                  This Agreement shall be interpreted wherever possible to avoid
                  conflicts   between  the  Sections  hereof  and  the  Addenda,
                  provided  that if such a conflict  shall  arise,  the  Addenda
                  shall control.

         1.2.     Whenever it is provided in this  Agreement  for a matter to be
                  mutually  agreed  upon  by the  parties  and set  forth  in an
                  Addendum to this  Agreement,  either  party may  initiate  the
                  process of  determining  such matter by  submitting a proposed
                  outline or contents of such Addendum to the other party.  Each
                  party shall appoint a primary contact and a secondary  contact
                  for the completion of such Addendum,  who shall be the contact
                  points for every issue  concerning such Addendum and who shall
                  be informed of the progress of the  project.  The names of the
                  contacts  will be exchanged  in writing by the parties.  Using
                  the  contacts,  the parties  shall work together in good faith
                  with such diligence as shall be commercially  reasonable under
                  the   circumstances  to  complete  such  Addendum,   provided,
                  however,  that neither  party shall be obligated to enter into
                  such an Addendum.  Upon the  completion of such  Addendum,  it
                  shall be set forth in a written  document  and executed by the
                  parties and shall become a part of this Agreement and shall be
                  deemed to be incorporated herein by reference.

                  below shall have the  meanings  given  below,  and all defined
                  terms shall include the plural as well as the singular. Unless
                  otherwise  stated,  the words "herein",  "hereunder" and other
                  similar words refer to this  Agreement as a whole and not to a
                  particular Section or other subdivision.  The words "included"
                  and "including" shall not be construed as terms of limitation.

                           liquidation  proceeding,  makes an assignment for the
                           benefit of creditors, admits in writing its inability
                           to pay debts when due.

                   serve as Bridge's point-of-contact for all matters concerning
                   its performance under this Agreement.

         8.2.      CONTRACT  MANAGER.  Bridge shall assign a  representative  to

9.       RIGHTS AND OBLIGATIONS OF BRIDGE

         9.1.      PROVISION OF THE SERVICES.  Bridge shall provide the Services
                   at the Service Sites  designated by SAVVIS in accordance with
                   the  Quality of  Service  Standards  and other  terms of this
                   Agreement.

         9.2.      ACCESS AND SECURITY.  Bridge personnel shall have such access
                   to SAVVIS' premises as is reasonably necessary to provide the

                   Bridge  personnel  shall  comply  at all times  with  SAVVIS'
                   reasonable security requirements. SAVVIS shall have the right
                   immediately  to  terminate  the right of access of any Bridge
                   personnel to any or all Service Sites should SAVVIS determine
                   in its sole  discretion  that such  termination is in SAVVIS'
                   best  interest,  provided that SAVVIS shall not exercise this
                   right on grounds  unrelated to job performance or in a manner
                   that obliges Bridge to commit an unlawful act.  Unless Bridge
                   knew or should  reasonably have known that particular  Bridge
                   personnel  would be  barred  from a  Service  Site,  the time
                   allowed for any installation,  repair, maintenance or similar
                   action that such  personnel were to perform shall be extended
                   for the  period  reasonably  required  by  Bridge  to  deploy
                   substitute personnel, provided that Bridge shall use its best
                   efforts to deploy  such  substitute  personnel  as quickly as
                   possible.  For purposes of this Section, any subcontractor or
                   other agent of Bridge shall be treated as Bridge personnel.

         9.3.     PROPER USE OF SAVVIS EQUIPMENT.

         9.3.1.    Bridge shall use any SAVVIS  Equipment in connection with the
                   Services  in  accordance   with  its   documentation,   which
                   documentation  shall be provided  by SAVVIS at no  additional
                   charge.

         9.3.2.    Bridge  shall be liable for  damages to the SAVVIS  Equipment
                   caused by the  negligence  or willful  acts or  omissions  of
                   Bridge's officers,  employees, agents or contractors, and for
                   damages to SAVVIS Equipment caused by the use of equipment or
                   supplies not authorized by SAVVIS.

                   9.3.3.    Bridge shall  neither  permit nor assist  others to
                             use the SAVVIS Equipment for any purpose other than
                             that for which they are intended,  and Bridge shall
                             be liable to SAVVIS for any direct  costs  incurred
                             by SAVVIS as a result of such use.

         9.4.      INSURANCE.

                   9.4.1.    At all  times  during  the term of this  Agreement,
                             Bridge  shall  maintain for itself,  its  officers,
                             employees,  agents and representatives insurance as
                             shall  be  provided  for  in an  Addendum  mutually
                             agreed  upon by the parties in the manner set forth
                             in Section 1.2 hereof.

                   9.4.2.    Bridge  shall  furnish  to  SAVVIS,   upon  written
                             request,   certificates   of   insurance  or  other
                             appropriate  documentation  (including  evidence of
                             renewal  of  insurance)  evidencing  the  insurance
                             coverage  referenced  above,  naming  SAVVIS  as an
                             additional  insured.  Such  certificates  or  other
                             documentation  shall  include a proviso  whereby 15
                             days prior  written  notice  shall be  provided  to
                             SAVVIS  prior  to  coverage  cancellation  or other
                             material   alteration   by  either  Bridge  or  the
                             applicable  insurer.  Such cancellation or material
                             alteration   shall  not   relieve   Bridge  of  its
                             continuing   obligation   to   maintain   insurance
                             coverage in accordance with this Section.

                   9.4.3.    In lieu of all or  part of the  insurance  coverage
                             specified in this Section,  Bridge may  self-insure
                             with  respect  to any  insurance  coverage,  except
                             where expressly prohibited by law.

         9.5.     REPRESENTATIONS AND WARRANTIES.

                   9.5.1.    Bridge  hereby  warrants  that the Services will be
                             provided in accordance  with the Quality of Service
                             Standards throughout the term of this Agreement. In
                             the event that  Bridge  fails to provide any of the
                             Services in accordance  with the Quality of Service
                             Standards, SAVVIS shall be entitled to recover from
                             Bridge (i) a refund of all  amounts  paid by SAVVIS
                             to  Bridge,  if  any,  for the  performance  of the
                             specific  Service that fails to meet the applicable
                             Quality of Service  Standards,  plus (ii) the costs
                             actually  incurred  by SAVVIS in order to have such
                             service  provided by a third  party,  to the extent
                             such costs are in excess of the amounts that SAVVIS
                             actually  paid,  or would have paid,  to Bridge for
                             the performance of the specific  Service that fails
                             to  meet  the   applicable   Quality   of   Service
                             Standards.

                   9.5.2.    THE FOREGOING  WARRANTIES  ARE IN LIEU OF ALL OTHER
                             WARRANTIES,   EXPRESS  OR  IMPLIED,  INCLUDING  THE
                             IMPLIED WARRANTIES OF  MERCHANTABILITY  AND FITNESS
                             FOR A PARTICULAR PURPOSE.

10.      LIMITATIONS OF LIABILITY

         10.1.    Neither  party  shall be liable  to the  other  for  indirect,
                  incidental,  consequential,  exemplary,  reliance  or  special
                  damages, including damages for lost profits, regardless of the
                  form of  action  whether  in  contract,  indemnity,  warranty,
                  strict  liability or tort,  including  negligence  of any kind
                  with  respect  to the  Services  or other  conduct  under this
                  Agreement.

         10.2.    Nothing  contained in this Section shall limit either  party's
                  liability  to  the  other  for  (a)  willful  or   intentional
                  misconduct, or (b) injury or death, or damage to tangible real
                  or  tangible  personal  property  or  the  environment,   when
                  proximately  caused by SAVVIS' or Bridge's  negligence or that
                  of  their  respective  agents,  subcontractors  or  employees.
                  Nothing   contained  in  this  Section  shall  limit  Bridge's
                  intellectual   property   indemnification   obligations  under
                  Section 13.

11.      PROPRIETARY RIGHTS; LICENSE

         11.1.    Bridge   hereby   grants   to  SAVVIS  a   non-exclusive   and
                  non-transferable  license  to  use  all  hardware,  equipment,
                  programming  and  software  necessary  for  SAVVIS  to use the
                  Services.  Such  license  is  granted  for  the  term  of this
                  Agreement  for the sole purpose of enabling  SAVVIS to use the
                  Services.

         11.2.    All title and property rights (including intellectual property
                  rights) to  Services  (including  associated  programming  and
                  software)  are and shall remain with Bridge.  SAVVIS shall not
                  attempt to examine, copy, alter, reverse engineer,  decompile,
                  disassemble,  tamper with or otherwise  misuse such  Services,
                  programming and software.

12.      CONFIDENTIALITY

         12.1.    During  the term of this  Agreement  and for a period  of five
                  years  from  the  date  of  its   expiration  or   termination
                  (including  all  extensions  thereof),  each  party  agrees to
                  maintain in strict  confidence all  Confidential  Information.
                  Neither  party shall,  without  prior  written  consent of the
                  other party,  use the other party's  Confidential  Information
                  for any purpose other than for the  performance  of its duties
                  and  obligations,  and the exercise of its rights,  under this
                  Agreement.   Each  party  shall  use,   and  shall  cause  all
                  authorized   recipients  of  the  other  party's  Confidential
                  Information  to use,  the same  degree of care to protect  the
                  other party's  Confidential  Information as it uses to protect
                  its own  Confidential  Information,  but in any event not less
                  than a reasonable degree of care.

         12.2.    Notwithstanding  Section  12.1,  either party may disclose the
                  Confidential  Information  of the  other  party  to:  (a)  its
                  employees  and the  employees,  directors  and officers of its
                  Affiliates  as  necessary  to implement  this  Agreement;  (b)
                  employees,  agents or  representatives  of the other party; or
                  (c) other persons (including counsel, consultants,  lessors or
                  managers of  facilities  or  equipment

                                       10

                  used by such party) in need of access to such  information for
                  purposes    specifically    related    to    either    party's
                  responsibilities  under  this  Agreement,  provided  that  any
                  disclosure of Confidential  Information under clause (c) shall
                  be made only upon prior  written  approval  of the other party
                  and subject to the  appropriate  assurances that the recipient
                  of such information shall hold it in strict confidence.

         12.3.    Upon the  request of the party  having  proprietary  rights to
                  Confidential  Information,  the  party in  possession  of such
                  information  shall  promptly  return it (including any copies,
                  extracts and  summaries  thereof,  in whatever form and medium
                  recorded) to the  requesting  party or, with the other party's
                  written  consent,  shall  promptly  destroy it and provide the
                  other party with written certification of such destruction.

         12.4.    Either party may request in writing that the other party waive
                  all or any portion of the requesting party's  responsibilities
                  relative to the other party's Confidential  Information.  Such
                  waiver request shall identify the affected information and the
                  nature of the proposed  waiver.  The  recipient of the request
                  shall respond within a reasonable  time and, if it determines,
                  in its sole discretion, to grant the requested waiver, it will
                  do so in writing over the signature of an employee  authorized
                  to grant such request.

         12.5.    Bridge  and  SAVVIS   acknowledge   that  any   disclosure  or
                  misappropriation  of Confidential  Information in violation of
                  this  Agreement  could cause  irreparable  harm, the amount of
                  which may be difficult to determine,  thus potentially  making
                  any  remedy  at  law or in  damages  inadequate.  Each  party,
                  therefore, agrees that the other party shall have the right to
                  apply to any  court  of  competent  jurisdiction  for an order
                  restraining  any breach or  threatened  breach of this Section
                  and for any other appropriate  relief.  This right shall be in
                  addition to any other remedy available in law or equity.

         12.6.    A party requested or ordered by a court or other  governmental
                  authority  of  competent   jurisdiction  to  disclose  another
                  party's Confidential  Information shall notify the other party
                  in  advance  of any such  disclosure  and,  absent  the  other
                  party's  consent to such  disclosure,  use its best efforts to
                  resist,  and to assist  the  other  party in  resisting,  such
                  disclosure.  A party providing  another  party's  Confidential
                  Information to a court or other  governmental  authority shall
                  use  its  best  efforts  to  obtain  a  protective   order  or
                  comparable  assurance  that the  Confidential  Information  so
                  provided will be held in confidence and not further  disclosed
                  to any other person, absent the owner's prior consent.

         12.7.    The  provisions  of  Section  12.1  above  shall  not apply to
                  reasonably  necessary  disclosures  in or in  connection  with
                  filings  under any  securities  laws,  regulatory  filings  or
                  proceedings,  financial  disclosures  which in the good  faith
                  judgment  of  the  disclosing   party  are  required  by  law,
                  disclosures   required  by  court  or  tribunal  or

                                       11

<PAGE>

                  competent jurisdiction,  or disclosures that may be reasonably
                  necessary in connection with the performance or enforcement of
                  this  Agreement or any of the  obligations  hereof;  provided,
                  however,  that  if the  receiving  party  would  otherwise  be
                  required to refer to or describe any aspect of this  Agreement
                  in any of the preceding  circumstances,  the  receiving  party
                  shall use its  reasonable  efforts  to take such  steps as are
                  available  under such  circumstances  (such as by  providing a
                  summary or  synopsis)  to avoid  disclosure  of the  financial
                  terms and conditions of this  Agreement.  Notwithstanding  any
                  provisions of this Agreement to the contrary, either party may
                  disclose  the terms and  conditions  of this  Agreement in the
                  course of a due diligence  review performed in connection with
                  prospective debt financing or equity  investment by, or a sale
                  to, a third party, so long as the persons  conducting such due
                  diligence  review have agreed to maintain the  confidentiality
                  of such  disclosure  and not to use  such  disclosure  for any
                  purpose other than such due diligence review.

13.      INDEMNIFICATIONS

         13.1.    Bridge shall defend,  settle,  or otherwise  manage at its own
                  cost and expense any claim or action  against SAVVIS or any of
                  its  directors,  officers,  employees or assigns for actual or
                  alleged  infringement  of any  patent,  copyright,  trademark,
                  trade secret or similar  proprietary  right to the extent that
                  such claim or action  arises from  Bridge's  provision  of the
                  Services.  SAVVIS shall notify  Bridge  promptly in writing of
                  any such claim or suit and shall  cooperate  with  Bridge in a
                  reasonable   way  to  facilitate  the  settlement  or  defense
                  thereof.  Bridge  further  agrees to indemnify and hold SAVVIS
                  harmless from and against any and all  liabilities and damages
                  (whether  incurred  as the  result of a  judicial  decree or a
                  settlement),  and the costs and expenses  associated  with any
                  claim  or  action  of the  type  identified  in  this  Section
                  (including reasonable attorneys' fees).

         13.2.    If,  as a  consequence  of a  claim  or  action  of  the  kind
                  described  in Section  13.1,  SAVVIS' or  Bridge's  use of any
                  Service or related documentation is enjoined, Bridge shall, at
                  its option and  expense,  either:  (a)  procure for SAVVIS the
                  right   to   continue   using   the   affected   Services   or
                  documentation;  (b) modify such  Service or  documentation  so
                  that it is  non-infringing,  provided  that such  modification
                  does  not  affect  the   intended   use  of  the   Service  or
                  documentation as contemplated  hereunder;  or (c) upon written
                  notice to SAVVIS, substitute for such Service or documentation
                  a   comparable,   non-infringing   product   or   service   or
                  documentation.  If  Bridge  does not  take any of the  actions
                  described  in  clauses  (a),  (b) and  (c),  then  SAVVIS  may
                  terminate  any  affected  Service  pursuant  to Section 5, and
                  Bridge shall refund to SAVVIS any prepaid charges therefor.

14.      DISPUTES

         14.1.    Resolution  of  any  and  all  disputes  arising  from  or  in
                  connection  with this  Agreement,  whether  based on contract,
                  tort,   statute  or   otherwise,   including   disputes

                                       12

<PAGE>


                  over  arbitrability  and disputes in connection with claims by
                  third persons  ("DISPUTES")  shall be exclusively  governed by
                  and settled in accordance  with the provisions of this Section
                  14. The  foregoing  shall not  preclude  recourse  to judicial
                  proceedings to obtain injunctive, emergency or other equitable
                  relief to enforce the provisions of this Agreement,  including
                  specific  performance,  and  to  decide  such  issues  as  are
                  required to be resolved in  determining  whether to grant such
                  relief. Resolution of Disputes with respect to claims by third
                  persons shall be deferred until any judicial  proceedings with
                  respect thereto are concluded.

         14.2.    The parties  hereby  agree to submit all  Disputes to rules of
                  arbitration of the American  Arbitration  Association  and the
                  Missouri  Uniform  Arbitration  Act (the  "RULES")  under  the
                  following  provisions,  which shall be final and binding  upon
                  the  parties,  their  successors  and  assigns,  and  that the
                  following  provisions  constitute a binding arbitration clause
                  under applicable law. Either party may serve process or notice
                  on the other in any  arbitration  or  litigation in accordance
                  with the notice  provisions  hereof.  The parties agree not to
                  disclose any information  regarding any Dispute or the conduct
                  of any arbitration hereunder,  including the existence of such
                  Dispute or such  arbitration,  to any  person or entity  other
                  than such employees or representatives of such party as have a
                  need to know.

         14.3.    Either party may commence proceedings hereunder by delivery of
                  written  notice  providing  a  reasonable  description  of the
                  Dispute to the other,  including a reference to this provision
                  (the "DISPUTE NOTICE").  Either party may initiate arbitration
                  of  a  Dispute  by   delivery  of  a  demand   therefor   (the
                  "ARBITRATION  DEMAND")  to the other  party not sooner than 60
                  calendar days after the date of delivery of the Dispute Notice
                  but at any time thereafter. The arbitration shall be conducted
                  in St. Louis, Missouri.

         14.4.    The arbitration  shall be conducted by three  arbitrators (the
                  "ARBITRATORS"),  one of whom shall be selected by Bridge,  one
                  by  SAVVIS,  and the third by  agreement  of the other two not
                  later than 10 days  after  appointment  of the first two,  or,
                  failing such agreement, appointed pursuant to the Rules. If an
                  Arbitrator  becomes  unable to  serve,  a  successor  shall be
                  selected  or  appointed  in  the  same  manner  in  which  the
                  predecessor Arbitrator was appointed.

         14.5.    The arbitration shall be conducted pursuant to such procedures
                  as the parties may agree or, in the absence of or failing such
                  agreement,   pursuant  to  the  Rules.   Notwithstanding   the
                  foregoing,  each party  shall  have the right to  inspect  the
                  books and  records  of the  other  party  that are  reasonably
                  related to the  Dispute,  and each party shall  provide to the
                  other,  reasonably  in advance of any  hearing,  copies of all
                  documents  which such party intends to present in such hearing
                  and the names and addresses of all witnesses  whose  testimony
                  such party intends to present in such hearing.

                                       13

<PAGE>


         14.6.    All hearings shall be conducted on an expedited schedule,  and
                  all proceedings shall be confidential. Either party may at its
                  expense make a stenographic record thereof.

         14.7.    The Arbitrators  shall complete all hearings not later than 90
                  calendar days after the Arbitrators' selection or appointment,
                  and shall make a final award not later than 30  calendar  days
                  thereafter.  The  Arbitrators  shall  apportion  all costs and
                  expenses of the Arbitration,  including the Arbitrators'  fees
                  and  expenses  of experts  ("ARBITRATION  COSTS")  between the
                  prevailing and non-prevailing  parties as the Arbitrators deem
                  fair and reasonable. In circumstances where a Dispute has been
                  asserted or defended  against on grounds that the  Arbitrators
                  deem manifestly  unreasonable,  the Arbitrators may assess all
                  Arbitration  Costs  against the  non-prevailing  party and may
                  include in the award the prevailing  party's  attorneys'  fees
                  and expenses in connection with any and all proceedings  under
                  this Section 14.

         14.8.    Either party may assert appropriate  statutes of limitation as
                  a defense in  arbitration;  provided,  that upon delivery of a
                  Dispute  Notice  any  such  statute  shall be  tolled  pending
                  resolution hereunder.

         14.9.    Pending the resolution of any dispute or  controversy  arising
                  under this  Agreement,  the parties shall  continue to perform
                  their respective obligations  hereunder,  and Bridge shall not
                  discontinue,  disconnect  or in any  other  fashion  cease  to
                  provide  all or any  substantial  portion of the  Services  to
                  SAVVIS unless otherwise directed by SAVVIS. This Section shall
                  not apply where SAVVIS is in default under this Agreement.

15.      FORCE MAJEURE

         15.1.    In no event shall  either party be liable to the other for any
                  failure  to  perform  hereunder  that  is due to  war,  riots,
                  embargoes, strikes or other concerted acts of workers (whether
                  of a party  hereto or of  others),  casualties,  accidents  or
                  other   causes  to  the  extent  that  such  failure  and  the
                  consequences  thereof  are  reasonably  beyond the control and
                  without the fault or negligence of the party claiming  excuse.
                  Each party shall, with the cooperation of the other party, use
                  reasonable  efforts to  mitigate  the extent of any failure to
                  perform and the adverse consequences thereof.

         15.2.    If Bridge cannot promptly provide a suitable  temporary Bridge
                  alternative  to  a  Service  subject  to  an  Interruption  in
                  connection  with the existence or a force  majeure  condition,
                  SAVVIS may, at its option and at its own cost,  contract  with
                  one or more third  parties  for (or provide for itself) any or
                  all affected Services for the shortest commercially  available
                  period likely to cover the reasonably expected duration of the
                  Interruption,  and  may  suspend  Bridge's  provision  of such
                  Services for such period.  Bridge shall not charge  SAVVIS for
                  any Services thus  suspended  during the period of suspension.
                  Bridge shall resume  provision of the suspended  Services upon
                  the later of the  termination or expiration of SAVVIS'

                                       14

<PAGE>

                  legally binding commitments under contracts with third parties
                  for  alternative  services or the  cessation  or remedy of the
                  force majeure condition.

         15.3.    In the event that a force majeure condition shall continue for
                  more than 60 days,  SAVVIS may cancel  the  affected  Services
                  with no further  liability  to Bridge  other than for Services
                  received  by  SAVVIS  prior  to the  occurrence  of the  force
                  majeure condition.

16.      GENERAL PROVISIONS

         16.1.    NO THIRD-PARTY BENEFICIARIES.  This Agreement shall not confer
                  any rights or  remedies  upon any person or entity  other than

                  upon and inure to the benefit of the parties  named herein and
                  their respective  successors and permitted  assigns.  No party
                  may  assign  either  this  Agreement  or any  of  its  rights,
                  interests,  or obligations hereunder without the prior written
                  approval  of the  other  party,  which  consent  shall  not be
                  unreasonably withheld.

                  default, misrepresentation,  or breach of warranty or covenant
                  hereunder,  whether  intentional  or not,  shall be  deemed to
                  extend to any prior or subsequent default,  misrepresentation,
                  or breach of warranty or covenant  hereunder  or affect in any
                  way any rights  arising  by virtue of any prior or  subsequent
                  such occurrence.

                  enforceability of the offending term or provision in any other

the Premises in its as-is  condition as modified by all work, if any,  performed
by Landlord at its expense prior to the respective  Delivery Dates in accordance
with the Work  Letter.  Except as provided  in and  subject to the Work  Letter,
Landlord has no  obligation  for the  completion  or remodeling of the Premises.
Tenant will accept the Premises in its "as is" condition on the Delivery Date.

     6. OPERATING EXPENSES.  Tenant shall pay additional Rent in accordance with
EXHIBIT C attached hereto.

     7. SERVICES.

     7.1 Subject to the provisions  below,  Landlord agrees,  without charge, in
accordance  with standards  reasonably  determined by Landlord from time to time
for the Building  consistent  with the standards  observed by operators of first
class  office  buildings in the northern  Virginia  market:  (1) at all hours to
furnish  running  water at those  points of supply for general use of tenants of
the Building;  (2) during Ordinary Business Hours and such other times as may be
required by Tenant to furnish to interior  Common Areas heated or cooled air (as
applicable),   electrical  current,   janitorial   services,   and  maintenance;
(3) during  Ordinary  Business  Hours and such other times as may be required by
Tenant to  furnish  heated or cooled  air to the  Premises  consistent  with the
design  capacity of the Building  HVAC;  (4) to furnish,  subject to capacity of
building systems,  unfiltered treated chilled water for use in Tenant's packaged
HVAC systems


                                       3
<PAGE>

provided  that such  systems are  approved  by  Landlord,  including  strainers,
pumping systems and controls;  (5) to provide,  during Ordinary  Business Hours,
the general use of  passenger  elevators  for ingress and egress to and from the
Premises (at least one such  elevator  shall be available at all times except in
the case of emergencies or repair);  (6) to provide janitorial  services for the
Premises in accordance with the attached EXHIBIT F (including  window washing of
the outside of exterior  windows and  relamping and  replacement  of ballasts in
flourescent  ceiling light fixtures in the Premises);  and (7) to cause electric
current to be supplied to the Premises for Tenant's  Standard  Electrical  Usage
(items (1) through (7) are collectively called  "Services").  "Tenant's Standard
Electrical  Usage"  means  electricity  for  normal  office  purposes  including
fluorescent and incandescent  lighting (including task and task ambient lighting
systems) and for normal office equipment,  including duplicating  (reproduction)
machines and personal  computers  (provided  they do not require any  additional
voltage,  special electrical or HVAC requirements beyond the systems existing in
the Premises),  and internal communications  systems.  "Ordinary Business Hours"
means 8:00 a.m. to 6:00 p.m. Monday through Friday and 8:00 a.m. to 1:00 p.m. on
Saturdays, Legal Holidays excepted. "Legal Holidays" mean New Year's Day, Martin
Luther King Day,  Inauguration Day, Presidents' Day, Memorial Day,  Independence
Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving Day, Christmas Day, and
such  other  national  holidays  hereafter  established  by  the  United  States
Government.  The  security  system  shall be  operative  at all times  except as
required for repair or maintenance and shall restrict access (in accordance with
the security  system  specifications)  to the main Building  lobby and access to
individual floors from the elevator on such days and at such hours as Tenant may
request by notice to Landlord; Tenant shall have access to the Building 24 hours
a day, 7 days a week  (subject to the  provisions  of this Lease).  Any security
system or other security  measures  (collectively  "security") that Landlord may
undertake are for  protection of the physical  structures  only and shall not be
relied upon by Tenant,  its  agents,  employees  or  invitees  to protect  their
person, or property,  including Tenant's Property.  Tenant shall not do anything
to circumvent or allow others to circumvent security.  Tenant shall have a right
to install its own security system in the Building  provided that such system is
installed in such a manner as to permit the  continued  operation of  Landlord's
security  and life safety  systems or is a substitute  security  system (for the
Building and Premises and Tenant's  allocated  portion of parking  level four of
the parking  garage,  as referred to in Section 29, but  excluding  the security
system for the main access controls for the parking garage), reasonably approved
by Landlord, that interfaces with Landlord's life safety systems to permit their
continued  operation.  Tenant shall provide Landlord with keys,  access cards or
access numbers for any security system installed by Tenant to permit Landlord to
have access to the Building and  Premises.  If a substitute  security  system is
used, Tenant shall deliver to Landlord, at the expiration or earlier termination
of the Lease,  all manuals and other  equipment  required  for  operation of the
system and leave in place all  cabling and related  equipment  installed  in the
Building.  Landlord  shall not be liable  for any  failure  of any  security  to
operate or for any  breach or  circumvention  of the  security  by  others,  and
Landlord makes no  representations  or warranties  concerning the  installation,
performance  and  monitoring  of the  security  or that it will  detect or avert
occurrences  which any such security is intended or expected to detect or avert.
Landlord shall maintain the security which it elects to install in good repair.

     7.2  Electricity  for the Building,  including the entirety of the Premises
shall be separately  metered and paid by Tenant upon billing by service provider
of Landlord (based on the actual costs incurred to the provider,  without markup
or profit to Landlord) and electricity shall not be included in amounts required
to be paid by Tenant as Operating Expenses under EXHIBIT C. In addition,  Tenant
shall be  responsible  for and shall pay promptly,  directly to the  appropriate
supplier, all charges for telephone,  interior landscape maintenance,  and other
materials and services furnished directly to Tenant or the Premises,  or used by
Tenant  in or about  the  Premises  during  the  Term,  together  with any taxes
thereon.  Tenant  shall have the right to  contract  for fiber optic cable to be
installed,  at Tenant's  expense,  from the street  right-of-way to the Premises
using  existing  conduits  installed by Landlord for use of this  Building or by
installation of additional conduits,  subject to Landlord's  reasonable approval
based on the  capacity,  design and location of such  conduits.  "Excess  Usage"
means any usage of electricity  (1) during other than Ordinary  Business  Hours;
(2) in an amount in excess of Tenant's  Standard  Electrical  Usage;  or (3) for
Special  Equipment  or for standard  HVAC  services  during other than  Ordinary
Business Hours.  "Special Equipment" means (a) any equipment consuming more than
0.5 kilowatts at rated  capacity,  (b) any  equipment  requiring a voltage other
than  120  volts,  single  phase,  or (c)  equipment  that  requires  the use of
self-contained  HVAC units.  If Tenant desires  Excess Usage,  Landlord will use
reasonable  efforts to supply the same. Tenant shall reimburse  Landlord for all
Landlord's  costs of providing  services for Excess Usage,  including  costs for
materials,   additional  wear  and  tear  on  equipment,  utilities,  and  labor
(including fringe and overhead costs). Computation of such costs will be made by
Landlord's  engineer,  based on his engineering survey of Tenant's Excess Usage.


                                       4
<PAGE>

Tenant shall reimburse  Landlord for all additional  costs, if any,  incurred by
Landlord as a result of Tenant's installation or use of Special Equipment, other
than electrical costs (which shall be included in the metered  electricity),  as
reasonably   determined   by  Landlord's   engineer,   including  all  costs  of
supplementing  the Building HVAC Systems and/or extending or  supplementing  any
electrical  service,  as Landlord  determines is necessary,  as a result of such
Special  Equipment.  "Special  Equipment"  means  (a)  any  equipment  requiring
modification or supplementation of the Building HVAC or electrical systems,  (b)
any  equipment  requiring a voltage other than 120 volts,  single phase,  or (c)
equipment that requires the use of self-contained  HVAC units. If Tenant desires
use of Building  services  after  Ordinary  Business  Hours,  Tenant  shall give
Landlord  such  prior  notice as is  reasonably  required  to  arrange  for such
after-hours services; provided, however, that only 2 hours prior notice shall be
required if such notice is given during  Ordinary  Business  Hours during Monday
through Friday (or such lesser notice as is required so long as after hours HVAC
is under the  control  of the  Charles E. Smith  Environmental  Control  Center,
pursuant to the applicable Building engineering services agreement). Charges for
Building HVAC use after Ordinary  Business  Hours, to be used in determining the
charges referred to above, are set forth on the attached EXHIBIT G. Tenant shall
also reimburse  Landlord for all costs of supplementing the Building HVAC System
and/or extending or supplementing any electrical service, as Landlord determines
is necessary, as a result of Tenant's Excess Usage. Prior to installation or use
of Special  Equipment or  operation  of the  Premises  for extended  hours on an
ongoing basis, Tenant shall notify Landlord of such intended installation or use
and obtain  Landlord's  consent.  Tenant may request  that  Landlord  install at
Tenant's  cost a check meter and/or flow meter to determine the cost of Tenant's
Excess  Usage.  Tenant shall also pay the cost of  replacing  light bulbs and/or
tubes and ballast used in all lighting in the Premises  other than that provided
by Landlord to all tenants of the Building.

     7.3 If Tenant  requires  janitorial  services  other than those included as
standard  Services,  Tenant shall  separately pay for such services monthly upon
billings by Landlord, or Tenant shall, at Landlord's option, separately contract
for such services  with the same company used by Landlord to furnish  janitorial
services to the Building.

     7.4  Landlord  may  discontinue,   reduce,   or  curtail  Services  (either
temporarily or permanently) when necessary due to accident beyond the reasonable
control of Landlord,  repairs, strikes, lockouts,  Applicable Laws, or any other
happening  beyond  Landlord's  reasonable  control.  Landlord  is not liable for
damages to Tenant or any other party as a result of any interruption, reduction,
or  discontinuance  of Services  (either  temporary or permanent)  nor shall the
occurrence  of any such event be  construed  as an eviction of Tenant,  cause or
permit an abatement,  reduction or setoff of Rent, or operate to release  Tenant
from  Tenant's   obligations;   provided,   however,  that  notwithstanding  the
foregoing,  if the  Premises  should  become  unsuitable  for  Tenant's use as a
consequence  of a cessation of Services  (other than an  interruption  resulting
from a fire or other  casualty,  which shall be governed  by the  provisions  of
Section 18) (excluding, however, acts or omissions of Tenant or Tenant's Agents,
as defined below) and persists for more than three (3) consecutive business days
(an  "Interfering  Event"),  then  Tenant  shall  be  entitled  to an  equitable
abatement  of Rent to the extent of the  interference  with  Tenant's use of the
Premises  occasioned  thereby from the date of the  Interfering  Event until the
date the Services are restored to the Premises.  If Tenant  continues to use any
part of the Premises to conduct its  business,  the Rent will only abate for the
untenantable part not used. Should any


                                       5
<PAGE>

malfunction of the Building improvements or facilities required to be maintained
by  Landlord  occur that  affect  such  Services,  Landlord  shall  repair  such
malfunction as soon as reasonably  practicable with reasonable  diligence and in
the event of the  discontinuance,  reduction or  curtailment of Services for any
reason, Landlord shall use commercially reasonable efforts to have such services
restored as soon as reasonably practicable.

     7.5 Tenant shall  promptly  notify  Landlord of any accidents or defects in
the Building of which Tenant has actual  knowledge,  including defects in pipes,
electric  wiring,  and HVAC  equipment,  and of any condition which is likely to
cause injury or damage to the Building or any person or property therein.

     8. QUIET  ENJOYMENT.  So long as an Event of Default has not  occurred  and
which is  continuing,  Tenant is entitled to the quiet  enjoyment  and  peaceful
possession of the Premises  subject to the  provisions  of this Lease.  Landlord
shall under no  circumstances  be held responsible for restriction or disruption
of access to the Building from public  streets  caused by  construction  work or
other actions taken by or on behalf of governmental authorities,  or for actions
taken by other  tenants  (their  employees,  agents,  visitors,  contractors  or
invitees), or any other cause not entirely within Landlord's direct control, and
same shall not constitute a constructive eviction of Tenant nor give rise to any
right or remedy of Tenant against  Landlord of any nature or kind. This covenant
of quiet  enjoyment  is in lieu of any covenant of quite  enjoyment  provided or
implied by law,  and Tenant  expressly  waives any such other  covenant of quiet
enjoyment to the extent broader than the covenant contained in this Section.

     9. DEPOSIT.

     9.1 By not later than 10 days  following  the  delivery  by Landlord of the
fully executed Lease to Tenant,  Tenant shall deposit,  and will keep on deposit
at all times during the Initial Term,  with Landlord the Deposit as security for
the payment and performance of Tenant's obligations under this Lease. If, at any
time,  after an Event of Default by  Tenant,  Landlord  has the right to use the
Deposit,  or so much thereof as necessary,  in payment of Rent, in reimbursement
of any expense  incurred by Landlord,  and in payment of any damages incurred by
Landlord by reason of such Event of  Default.  In such  event,  Tenant  shall on
demand of Landlord  forthwith  remit to Landlord a sufficient  amount in cash to
restore the Deposit to the original  amount.  If the entire Deposit has not been
utilized,  the remaining amount will be refunded to Tenant or to whoever is then
the holder of Tenant's interest in this Lease, without interest,  within 60 days
after  expiration  of the  Initial  Term.  Landlord  may deliver the Deposit (or
rights to the  Deposit  account,  as  referred  to above)  to any  purchaser  of
Landlord's  interest in the  Premises  and  Landlord  shall be  discharged  from
further  liability  therefor  following  actual  delivery  of such  Deposit  and
assumption by the  transferee of Landlord's  obligations  with respect  thereto.
Tenant  agrees  that if a  Mortgagee  succeeds  to  Landlord's  interest  in the
Premises by reason of foreclosure or deed in lieu of foreclosure,  Tenant has no
claim against the Mortgagee for the Deposit or any portion  thereof  unless such
Mortgagee has actually  received the same from  Landlord.  If claims of Landlord
exceed the Deposit, Tenant shall remain liable for the balance.

     9.2  Subject  to the  provisions  of Section  9.4,  if there is no Event of
Default  by  Tenant  as of the end of the end of the 36th  month  following  the
Commencement Date or circumstances which with the mere passage of time or giving
of notice would constitute an Event of Default  following such date, the Deposit
shall be  reduced by  $184,667.08;  if there is Event of Default by Tenant as of
the  end of the  end of the  36th  month  following  the  Commencement  Date  or
circumstances  which  with the mere  passage  of time or giving of notice  would
constitute an Event of Default,  such reduction shall occur thereafter only upon
the  curing of such  Event of  Default  or  circumstances,  as  applicable.  The
remaining  Deposit  shall then be held for the balance of the Initial Term until
the  Expiration  Date (as provided in Section 1.3),  subject to  application  in
accordance with this Section.

     9.3 The  Deposit  shall  be in the  form  of  immediately  available  funds
deposited  in a separate  interest-bearing  account in  Landlord's  name,  which
interest shall be considered  additional Deposit or,  alternatively Tenant shall
have  the  right  to  request  Landlord's  consent  to  the  substitution  of an
irrevocable transferable letter of credit for the Deposit and Landlord shall not
withhold  consent to such  substitution  subject to such letter of credit  being
issued by a lending  institution  approved by Landlord  and the letter of credit
being in a form approved by Landlord ("Letter of


                                       6
<PAGE>

Credit"), such approval not to be unreasonably withheld, conditioned or delayed,
in the amount of the Deposit,  subject to reduction  as provided  above.  If the
Letter of Credit would  otherwise  expire prior to the Expiration  Date,  Tenant
shall  present  Landlord  with an extension or renewal of the initial  Letter of
Credit,  or a  substitute  Letter of Credit in the same form,  not later than 60
days prior to the  expiration  date of such  initial  Letter of  Credit,  from a
lending institution subject to Landlord's  reasonable approval;  such extension,
renewal or substitute  Letter of Credit shall be effective no later than the day
prior to the  expiration of the initial  Letter of Credit and shall  continue in
effect for not less than the period ending with the Expiration Date and shall be
in the  amount  provided  above.  Tenant  agrees  that in an Event of Default by
Tenant (as defined in Section  20),  Landlord  shall have a right to present the
Letter of Credit (or the renewal,  extension or  substitute)  for payment,  with
amounts  received to be held and applied in accordance  with this  Section.  Any
failure of Tenant to provide  Landlord with an extension,  renewal or substitute
Letter of Credit,  as  required  hereunder,  shall be deemed an Event of Default
under the Lease and Landlord  shall have a right to present the Letter of Credit
in accordance with the foregoing provision. If the Letter of Credit has not been
presented  for  payment  in  accordance  with  this  Section  on or  before  the
Expiration  Date,  Landlord  shall return the Letter of Credit to Tenant  within
thirty (30) days after the Expiration  Date.  Tenant agrees that in the event of
any  assignment  or this  Lease or  mortgage,  Landlord  shall have the right to
transfer the Letter of Credit or  substitute  to the assignee or mortgagee  (and
Tenant  shall  pay any  costs or fees  charged  by the  issuer  to  permit  such
transfer),  and if the Letter of Credit has been  transferred as provided above,
Tenant  shall  look  solely to such  transferee  for the return of the Letter of
Credit (or  substitute),  provided  that Landlord  shall give written  notice to
Tenant of transfer of Landlord's interest resulting in transfer of the Letter of
Credit and the  transferee  shall  assume the  obligation  to return the same to
Tenant in accordance  with this Lease.  Landlord shall deliver the  then-current
effective  Letter of Credit to Tenant upon receipt of any conforming  renewal or
substitute  Letter of Credit  provided in  accordance  with this  Paragraph  and
cooperate  with the  issuing  bank to effect the  release  of such  then-current
effective Letter of Credit.

     9.4 In accordance  with  Paragraph 6 of the Addendum,  the  obligations  of
Tenant are  guaranteed by the Guarantor,  Bridge  Information  Systems,  Inc., a
Missouri  corporation,  pursuant  to the  terms of the  Guaranty.  The  Guaranty
provides  for the ability to  substitute  Tenant's  parent  corporation,  Savvis
Communications  Corporation,  a Delaware corporation,  as Guarantor,  subject to
increasing the amount of the Deposit to a total of  $3,196,419.30 in the form of
the Letter of Credit referred to above; the effective date of such  substitution
is referred to as the Substitution Date. In such event, the following  provision
shall be applicable,  in  substitution  for the provisions of Section 9.2 above:
(i) if there  is no  Event of  Default  (or  circumstances  which  with the mere
passage of time or giving of notice  would  constitute  an Event of  Default) by
Tenant  as of the end of the  12th  month  following  the  Substitution  Date or
circumstances  which  with the mere  passage  of time or giving of notice  would
constitute an Event of Default following such date, the Deposit shall be reduced
by  $351,107.29;   (ii)  likewise,   on  each  anniversary   thereafter  of  the
Substitution  Date through and  including  the 7th  anniversary,  if there is no
Event of Default (or circumstances which with the mere passage of time or giving
of notice  would  constitute  an Event of Default) as of such date,  the Deposit
shall be additionally  reduced by $351,107.29  (however,  in no event shall such
reductions  result  in  reduction  below   $738,668.32);   (iii)  if  there  are
circumstances  which  with the mere  passage  of time or giving of notice  would
constitute  an  Event  of  Default  as of  the  respective  anniversary  of  the
Substitution Date, the respective reduction shall occur thereafter only upon the
curing of such  Event of  Default  or  circumstances,  as  applicable;  (iv) the
remaining  Deposit as of the 7th  anniversary of $738,668.32  shall then be held
until the  Expiration  Date of the  Initial  Term,  subject  to  application  in
accordance  with this Section.  The reduction of the amount of the Deposit shall
be effected by amendment of the  then-effective  Letter of Credit (by  amendment
executed by the issuer and Landlord) or by Tenant's substitution of a substitute
Letter of Credit in the respective reduced amount (in which event Landlord shall
surrender the Letter of Credit being held as of the substitution upon receipt of
the substitute).

     10.  CHARACTER  OF  OCCUPANCY.  Tenant  shall  occupy the  Premises for the
Permitted  Use and for no other  purpose,  and use it in a  careful,  safe,  and
proper manner and pay on demand for any damage to the Premises  caused by misuse
or abuse by Tenant,  Tenant's agents or employees,  or any other person entering
upon the Premises under express or implied  invitation of Tenant  (collectively,
"Tenant's Agents").  The term "Permitted Use" shall mean: general office use for
administrative,  clerical, and professional office purposes and the operation of
internet and telecommunications services and Collocation Services (as defined in
Section 14.7)  (collectively,  the "Primary Use") and for  activities  ancillary
thereto (the  "Ancillary  Uses")  provided that  Ancillary Uses shall not be the
primary use of


                                       7
<PAGE>

the Premises, are permitted by Applicable Laws (as hereinafter defined), and are
expressly  approved  by  Landlord,  which  approval  shall  not be  unreasonably
withheld if such uses are consistent  with first class  suburban  general office
building uses and so long as in keeping with Building's  first-class quality and
allowed under PDC zoning applicable to the Building. Tenant shall be responsible
for  obtaining any  approvals or permits  required for the Ancillary  Uses under
Applicable Laws and the Declaration.  Tenant, at Tenant's expense,  shall comply
with  all  applicable  federal,  state,  city,  quasi-governmental  and  utility
provider  laws,  codes,  rules,  and  regulations  now or  hereafter  in  effect
("Applicable  Laws") which impose any duty upon  Landlord or Tenant with respect
to the  occupation or  alteration  of the  Premises.  Tenant shall not commit or
permit waste or any nuisance on or in the Premises.  Tenant agrees not to store,
keep, use, sell,  dispose of or offer for sale in, upon or from the Premises any
article or substance  prohibited by any insurance  policy  covering the Building
Complex nor shall Tenant keep,  store,  produce or dispose of on, in or from the
Premises or the Building Complex any substance which may be deemed an infectious
waste or hazardous  substance under any Applicable Laws, except customary office
and cleaning supplies or supplies customarily associated with the Primary Use of
the  Premises  that  are  disclosed  to  Landlord  and are  stored  and  used in
accordance with Applicable Laws and applicable industry  standards.  Landlord is
responsible  for  complying  with  Applicable  Laws  relating  to  the  Building
(excluding  the  Premises)  and its  Common  Areas,  including  Title III of the
Americans  with  Disabilities  Act of 1990  (the  "ADA")  and the  costs of such
compliance  with existing  Applicable Laws as of the date hereof will be paid by
Landlord  and will not be  charged  back to  Tenant.  The  method  and timing of
compliance  will be within  Landlord's  discretion.  Tenant is  responsible  for
compliance with all existing and any new Applicable Laws,  including ADA, within
the Premises.  Landlord will include  Landlord's  future compliance costs due to
changes in or new  Applicable  Laws as an Operating  Expense in accordance  with
Exhibit  C. To the  extent  that  Tenant  is  responsible  for  compliance  with
Applicable  Laws,  Tenant  shall  have  the  right  to  contest  by  appropriate
proceedings  diligently  conducted in good faith, in the name of Tenant or, with
the prior written  consent of Landlord,  in the name of Landlord,  or both,  the
validity or application of any Applicable Laws of any nature affecting Tenant or
its use of the Premises.  If compliance with any of such Applicable Laws legally
may be delayed pending the prosecution of any proceeding,  without incurring any
lien,  charge or liability of any kind against the Building and/or the Premises,
or against  Landlord's  interest in the Building  and/or the Premises or sale of
the Building and/or the Premises,  and without  subjecting Tenant or Landlord to
any  liability,  civil or  criminal,  interest or penalty for failure to comply,
Tenant may delay compliance until the final determination of the proceeding.

     11. MAINTENANCE, ALTERATIONS AND REENTRY BY LANDLORD.

     11.1 Landlord will (i) make repairs and  replacements to HVAC,  mechanical,
life safety and  electrical  systems in the Premises (to the extent such systems
are Building standard) deemed necessary by Landlord for normal operations of the
Building  Complex;  and (ii)  provide  upkeep,  maintenance,  and repairs to all
Common Areas of the Building Complex,  including without  limitation the Parking
Facilities,  and all  structural  elements of the  Building,  including  without
limitation the roof,  exterior  walls  (including  windows and glass),  interior
bearing walls, foundations, footings, and all exterior surfaces of the Building.
Landlord  shall  perform its  obligations  under this  Section  11.1 in a manner
consistent with other first class office buildings in the northern Virginia area
and in accordance  with Applicable  Laws.  Except as provided in this Section or
otherwise  expressly  required in this Lease,  Landlord is not  required to make
improvements or repairs to the Premises during the Term.

     11.2  Landlord  or  Landlord's  agents may at any time  enter the  Premises
without notice in case of emergency and for  performance of janitorial  services
and in all other  instances  after  reasonable  prior oral or written  notice to
Tenant and subject to compliance  with  Tenant's  reasonable  security  measures
(which may include an escort) for examination and inspection,  or to perform, if
Landlord elects, any obligations of Tenant which Tenant fails to perform or such
cleaning, maintenance, janitorial services, repairs, replacements, additions, or
alterations  as  Landlord  deems  necessary  for  the  safety,  improvement,  or
preservation  of the Premises or other  portions of the  Building  Complex or as
required by Applicable  Laws.  Landlord or  Landlord's  agents may also show the
Premises to prospective purchasers,  Mortgagees and during the last 12 months of
the Term, to prospective tenants,  upon not less than 48 hours prior notice. Any
such reentry does not  constitute an eviction or entitle  Tenant to abatement of
Rent.  Landlord may make such  alterations  or changes in other  portions of the
Building Complex as Landlord desires so long as such alterations and


                                       8
<PAGE>

changes do not unreasonably interfere with Tenant's occupancy of the Premises or
use of the Common  Areas or conflict  with the other  provisions  of this Lease.
Landlord  may use the  Common  Areas  and one or more  street  entrances  to the
Building  Complex as may be necessary in  Landlord's  judgment to complete  such
work.

     12. ALTERATIONS AND REPAIRS BY TENANT.

     12.1 Tenant shall not make any alterations to the Premises during the Term,
including installation of equipment or machinery which requires modifications to
existing  electrical  outlets or increases  Tenant's usage of electricity beyond
Tenant's Standard Electrical Usage (collectively  "Alterations") without in each
instance first  obtaining the written  consent of Landlord,  which consent shall
not be  unreasonable  withheld,  conditioned or delayed.  Landlord's  consent or
approval of the plans,  specifications  and working drawings for any Alterations
shall not constitute any warranty or  representation  by Landlord (and shall not
impose any liability on Landlord) as to their completeness,  design sufficiency,
or compliance with  Applicable  Laws;  provided,  however,  Tenant may,  without
Landlord's consent,  perform interior  non-structural  Alterations not involving
modifications  to the Base  Building  plumbing,  electrical,  mechanical or life
safety  systems (as  distinguished  from the  portions of such  systems  located
within the  Premises  that are  installed  by Tenant as Initial  Tenant  Finish)
provided the cost of any particular  Alterations  (taking into account  together
all  Alterations  being made as part of a common or phased plan) does not exceed
Seventy Five Thousand Dollars  ($75,000)(such  cost limit shall not, however, be
applicable to Alterations  on the 6th floor).  Tenant shall at its cost: pay all
engineering and design costs incurred by Landlord as to all Alterations,  obtain
all governmental permits and approvals required, and cause all Alterations to be
completed in compliance  with  Applicable  Laws and  requirements  of Landlord's
insurance.  All such work relating to  Alterations  shall be performed in a good
and  workmanlike  manner,  using new  materials  and equipment at least equal in
quality to the Initial Tenant Finish.  All  Alterations,  repair and maintenance
work  performed  by  Tenant  shall be done at  Tenant's  expense  by  Landlord's
employees or, with  Landlord's  prior consent,  which shall not be  unreasonably
withheld, conditioned or delayed, by other persons requested by Tenant; however,
if such work is not performed by Landlord's employees, Tenant shall pay Landlord
a  supervisory  fee upon  receipt of an  invoice.  If Landlord  authorizes  such
persons to perform work,  Tenant shall deliver to Landlord prior to commencement
certificates issued by insurance companies qualified to do business in the state
in which the Premises are located, evidencing that worker's compensation, public
liability insurance,  and property damage insurance (in amounts,  with companies
and on forms  satisfactory  to  Landlord)  are in force  and  maintained  by all
contractors  and  subcontractors  engaged to perform  such work.  All  liability
policies  shall name  Landlord,  Building  Manager,  and Mortgagee as additional
insureds.  Each certificate shall provide that the insurance may not be canceled
or modified  without 10 days' prior  written  notice to Landlord and  Mortgagee.
Landlord  also has the  right  to post  notices  in the  Premises  in  locations
designated by Landlord  stating that Landlord is not responsible for payment for
such work and containing such other information as Landlord deems necessary. All
such work shall be performed in a manner which does not  unreasonably  interfere
with the performance of Landlord's  rights and obligations  under this Lease, or
impose  additional  expense  upon  Landlord  in the  operation  of the  Building
Complex.

     12.2 Tenant shall keep the Premises in as good order, condition, and repair
and in an orderly  state,  as on the  Commencement  Date,  loss by fire or other
casualty or ordinary wear excepted.

     12.3 All Alterations,  including partitions, paneling, carpeting, drapes or
other window  coverings,  and light  fixtures (but not including  movable office
furniture,  equipment  and  other  property  not  permanently  attached  to  the
Building), are deemed a part of the real estate and the property of Landlord and
remain upon and be surrendered with the Premises at the end of the Term, whether
by lapse of time or otherwise,  unless Landlord notifies Tenant no later than 15
days  prior to the end of the Term that it elects to have  Tenant  remove all or
part of such  Alterations,  and in such event,  Tenant shall at Tenant's expense
promptly remove the Alterations  specified and restore the Premises to its prior
condition, reasonable wear and tear excepted.

         13.  CONSTRUCTION  LIENS.  Tenant  shall  pay for all work  done on the
Premises by Tenant or at its request (other than the Initial Tenant Finish) of a
character  which may result in liens on  Landlord's  or  Tenant's  interest  and


                                       9
<PAGE>

Tenant will keep the Premises free of all construction liens, and other liens on
account of such work. Tenant  indemnifies,  defends,  and saves Landlord and all
Mortgagees  harmless from all liability,  loss,  damage, or expenses,  including
attorneys' fees, on account of any claims of laborers, materialmen or others for
work  performed  or for  materials  or supplies  furnished  to Tenant or persons
claiming under Tenant.  If any lien is recorded against the Premises or Building
or any suit  affecting  title  thereto is commenced as a result of such work, or
supplying  of  materials,  Tenant  shall cause such lien to be removed of record
within 10 days after  notice  from  Landlord.  If Tenant  desires to contest any
claim, Tenant must either arrange for release of such lien and substitution of a
bond or other  collateral  (in  accordance  with  Applicable  Laws)  or  furnish
Landlord  adequate  security  of at least 150% of the amount of the claim,  plus
estimated costs and interest and, if a final judgment  establishing the validity
of any lien is entered,  Tenant shall  immediately  pay and satisfy the same. If
Tenant  fails to  proceed as  aforesaid,  Landlord  may pay such  amount and any
costs, and the amount paid,  together with reasonable  attorneys' fees incurred,
shall be immediately due Landlord upon notice.

     14. SUBLETTING AND ASSIGNMENT.

     14.1 Except as provided in Section  14.7,  Tenant shall not sublet any part
of the  Premises  nor assign or  otherwise  transfer  this Lease or any interest
herein  (sometimes  referred to as "Transfer," and the subtenant or assignee may
be referred  to as  "Transferee")  without  the consent of Landlord  first being
obtained,  which  consent  will not be  unreasonably  withheld,  conditioned  or
delayed  provided that: (1) Tenant complies with the provisions of Section 14.4;
(2)  Landlord  declines to  exercise  its rights  under  Section  14.3;  (3) the
Transferee is engaged in a business and the portion of the Premises will be used
for the Permitted Use in a manner which is in keeping with the then standards of
the Building and does not conflict with any exclusive use rights  granted to any
other  tenant  of the  Building  Complex;  (4)  the  Transferee  has  reasonable
financial worth in light of the responsibilities  involved; (5) Tenant is not in
default  at  the  time  it  makes  its  request;  (6)  the  Transferee  is not a
governmental  or  quasi-governmental  agency;  and (7) the  Transferee  is not a
tenant or currently  negotiating a lease with Landlord in any building  owned by
Landlord  in the  metropolitan  area  of the  Building  Complex  (including  the
Building  Complex).  Transfer  includes a sale by Tenant of substantially all of
its  assets or stock if Tenant is a  publicly  traded  corporation,  a merger of
Tenant with another  corporation,  the transfer of 49% or more of the stock in a
corporate tenant whose stock is not publicly traded,  or transfer of 49% or more
of the  beneficial  ownership  interests in a partnership  or limited  liability
company  tenant.  If any  Alterations  to the  Premises or the Common  Areas are
required by Applicable  Laws in connection  with such Transfer or the particular
business  of such  Transferee,  such  Alterations  shall be subject to the prior
approval of Landlord  (which  approval shall not be  unreasonably  withheld) and
Tenant shall bear the cost of such Alterations.

     14.2  Following any Transfer in accordance  with this Section 14,  Landlord
may, during the continuance of an Event of Default by Tenant,  collect rent from
the  Transferee or occupant and apply the net amount  collected to the Rent, but
no Transfer or  collection  will be deemed an  acceptance  of the  Transferee or
occupant as Tenant or release Tenant from its obligations. Consent to a Transfer
shall  not  relieve  Tenant  from  obtaining  Landlord's  consent  to any  other
Transfer.  Notwithstanding  Landlord's  consent  to  a  Transfer,  Tenant  shall
continue to be primarily liable for its obligations. If Tenant collects any rent
or other amounts from a Transferee in excess of the Rent (after deduction of the
reasonable  costs of such  Transfer)  for any monthly  period,  Tenant shall pay
Landlord fifty percent (50%) of the excess monthly, as and when received.

     14.3  Notwithstanding  the above (and except for a Transfer permitted under
Section 14.7),  if Tenant requests  Landlord's  consent to sublet 49% or more of
the Premises for all or  substantially  all of the remainder of the then-current
Term of the Lease or assign Tenant's interest in the Lease,  Landlord may refuse
to grant such consent in its sole  discretion and terminate this Lease as to the
portion  of the  Premises  with  respect to which such  consent  was  requested;
provided,  however,  if Landlord  does not consent and elects to  terminate  the
Lease as to such  portion,  Tenant may within 15 days after notice from Landlord
to this effect  withdraw  Tenant's  request  for  consent.  If such  termination
occurs,  it shall be effective on the date  designated in a notice from Landlord
and shall not be more than 30 days following such notice.


                                       10
<PAGE>

     14.4 Tenant must notify Landlord at least 30 days prior to the desired date
of the  Transfer  ("Tenant's  Notice"),  excluding  a Transfer  permitted  under
Section 14.7.  Tenant's  Notice shall describe the portion of the Premises to be
transferred and the terms and conditions.  Landlord has, without obligation,  15
days  following  receipt of Tenant's  Notice to (i) propose a subtenant for such
space (which  subtenant  shall be subject to  reasonable  approval of Tenant) or
(ii) exercise its rights pursuant to Section 14.3 if Tenant's  Notice  discloses
that 49% or more of the Premises is involved; provided, however, that Landlord's
option in  clause  (i) shall not be  applicable  until 24 months  following  the
Commencement  Date so long as the  Transfers  are  subleases for a period not to
exceed 36 months which which do not involve more than 33% of the Premises in the
aggregate.  If the space covered by Tenant's  Notice is subleased to a sublessee
proposed by Landlord, rent and other sums due from the subtenant will be paid to
Tenant directly and Landlord has no  responsibility  for the performance by such
subtenant of its  obligations  under its sublease with Tenant.  If Landlord does
not  exercise  its rights  under  clause (i) or clause (ii) within 15 days after
receipt of Tenant's  Notice,  Landlord shall be deemed to have waived its rights
under those clauses with respect to the proposed transaction and Tenant shall be
free to sublet the specified portion of the Premises to any third party on terms
substantially  identical  to those  described  in  Tenant's  Notice,  subject to
Landlord's consent as set forth above. If Tenant does not sublet such portion of
the Premises within 180 days following Landlord's notice to Tenant,  Tenant must
reoffer the Premises to Landlord in accordance with the provisions  hereof prior
to subleasing to a third party.

     14.5 All documents utilized by Tenant to evidence a Transfer are subject to
approval by Landlord. Tenant shall pay Landlord's reasonable expenses, including
reasonable  attorneys' fees, of determining  whether to consent and in reviewing
and approving the documents. Tenant shall provide Landlord with such information
as  Landlord  reasonably  requests  regarding a proposed  Transferee,  including
financial information.

     14.6 If a trustee or debtor in  possession  in  bankruptcy  is  entitled to
assume control over Tenant's  rights under this Lease and assigns such rights to
any third party  notwithstanding  the provisions  hereof, the rent to be paid by
such party shall be  increased  to the current  Base Rent (if greater  than that
being paid for the Premises) which Landlord  charges for comparable space in the
Building as of the date of such third party's occupancy. If Landlord is entitled
under the Bankruptcy Code to "Adequate  Assurance" of future performance of this
Lease, the parties agree that such term includes the following:

     (1) Any assignee must demonstrate to Landlord's  reasonable  satisfaction a
net  worth  (as  defined  in  accordance  with  generally  accepted   accounting
principles consistently applied) at least as large as the net worth of Tenant on
the  Commencement  Date  [increased by 4%,  annually,  for each year  thereafter
through  the date of the  proposed  assignment]  or other  equivalent  financial
capacity.  Tenant's financial condition was a material inducement to Landlord in
executing this Lease.

     (2) The  assignee  must assume and agree to be bound by the  provisions  of
this Lease.

     14.7  Notwithstanding  anything to the contrary  contained  hereinabove but
subject to Section 14.2 and provided that the  conditions of clauses (3) and (5)
of Section 14.1 are met, Tenant may, without obtaining  Landlord's prior written
consent,  assign or sublease all or any portion of the Premises to the following
parties on the following  conditions:  (1) any  subsidiary or affiliate in which
Tenant has, directly or indirectly, an ownership interest of more than 50%; (ii)
any direct or ultimate  parent of Tenant;  (iii) any  subsidiary or affiliate in
which Tenant's  parent owns,  directly or  indirectly,  by means of an ownership
interest  of more than 50%;  or (iv) any  corporation  into which  Tenant may be
merged or consolidated or which purchases all or substantially all of the assets
or stock of Tenant  provided that the resulting  corporation  has a net worth at
least equal to Tenant's net worth as of the date  hereof.  A sale or transfer of
stock in Tenant pursuant to a public offering,  including  publicly traded stock
or  Tenant,  shall be  permitted  without  obtaining  Landlord's  prior  written
consent.  As soon as  practicable  prior to the effective  date of a transaction
permitted   under  this  Section  14.7,   Tenant  will  provide   Landlord  with
documentation  evidencing  such  transaction and such other evidence as Landlord
may reasonably require to establish that such transaction falls within the terms
and  provisions  of this  Section.  Furthermore,  Tenant may allow  employees of
companies  to whom  Tenant is  providing  products or  services  (including  the
maintenance


                                       11
<PAGE>

and  operation of computer  servers for such  companies) or with which Tenant is
collaborating   in  the   development  or  provision  of  products  or  services
(collectively  referred to as  "Collocation  Services")  to work in the Premises
without  Landlord's  consent and without being deemed to have sublet any portion
of the  Premises,  so  long as such  employees  do not  occupy  space  which  is
separated  from that occupied by Tenant by demising walls and the number of such
employees  whose primary place of employment is the Premises does not exceed ten
percent (10%) of the total number of persons regularly occupying the Premises.

     15. DAMAGE TO PROPERTY. Tenant agrees Landlord is not liable for any injury
or damage,  either  proximate  or remote,  occurring  through or caused by fire,
water, steam, or any repairs, alterations,  injury, accident, or any other cause
to the Premises,  to any  furniture,  fixtures,  Tenant  improvements,  or other
personal property of Tenant kept or stored in the Premises, or in other parts of
the  Building  Complex,  whether  by  reason of the  negligence  or  default  of
Landlord,  other occupants,  any other person, or otherwise;  and the keeping or
storing of all property of Tenant in the Premises and Building Complex is at the
sole risk of Tenant.

     16. INDEMNITY TO LANDLORD.

     16.1 Tenant  agrees to  indemnify,  defend,  and hold Landlord and Building
Manager harmless from all liability,  costs, or expenses,  including  attorneys'
fees,  on  account  of damage  to the  person or  property  of any third  party,
including any other tenant in the Building Complex,  to the extent caused by the
negligence or breach of this Lease by the Tenant or Tenant's Agents.

     16.2  Tenant  shall  maintain  throughout  the  Term a  commercial  general
liability  policy,  including  protection  against  death,  personal  injury and
property damage,  issued by an insurance company qualified to do business in the
state in which the Premises  are  located,  with a single limit of not less than
$1,000,000.00.  Such policy shall name Landlord, Building Manager, and Mortgagee
as  additional  insureds,  be primary  to any other  similar  insurance  of such
additional  insureds,  and  provide  that it may not be  cancelled  or  modified
without at least 20 days' prior  notice to Landlord and  Mortgagee.  The minimum
limits of such insurance do not limit the liability of Tenant  hereunder.  Prior
to  occupancy  of the  Premises,  and prior to  expiration  of the  then-current
policy,  Tenant shall deliver  certificates  evidencing that insurance  required
under this Lease is in effect.

     16.3 Landlord  agrees to indemnify,  defend,  and hold Tenant harmless from
all liability,  costs,  or expenses,  including  attorneys'  fees, on account of
damage to the person or property of any third party (excluding  Tenant's Agents)
including any other tenant in the Building Complex,  to the extent caused by the
negligence  or breach of this Lease by Landlord,  subject to the  provisions  of
Section 18.6

     17. SURRENDER AND NOTICE.  Upon the expiration or other termination of this
Lease,  Tenant  shall  immediately  quit and  surrender to Landlord the Premises
broom clean,  in good order and  condition,  ordinary  wear and tear and loss by
fire or other  casualty  excepted,  and Tenant  shall  remove all of its movable
furniture and other effects,  all telephone  cable and related  equipment in the
Building  installed for Tenant, and such Alterations,  as Landlord requires.  If
Tenant fails to timely vacate the Premises as required, Tenant is responsible to
Landlord for all resulting costs and damages of Landlord,  including any amounts
paid to third parties who are delayed in occupying the Premises.

     18. INSURANCE, CASUALTY, AND RESTORATION OF PREMISES.

     18.1 Landlord shall maintain  property  insurance for the Building Complex,
the shell and core of the Building and the Premises in such  amounts,  from such
companies, and on such terms and conditions, sufficient to prevent Landlord from
being a coinsurer under its policy of insurance,  for property loss equal to the
full replacement value of the Building Complex and public liability insurance in
an amount customary for first class office  properties in the Northern  Virginia
area.


                                       12
<PAGE>

     18.2 Tenant shall maintain  throughout the Term insurance coverage at least
as broad as ISO Special Form Coverage  against risks of direct  physical loss or
damage  (commonly known as "all risk") for the full replacement cost of Tenant's
property and betterments in the Premises,  including  tenant finish in excess of
the Initial Tenant Finish.

     18.3 If the Building is damaged by fire or other casualty which renders the
Premises  wholly  untenantable  and the damage is so extensive that an architect
selected by Landlord  certifies in writing to Landlord and Tenant within 30 days
of said  casualty (or such longer  period,  not to exceed a total of 45 days, if
Landlord  is unable to obtain  such  certification  within the 30 day period for
causes beyond Landlord's  reasonable control) that the Premises cannot, with the
exercise of reasonable  diligence,  be made fit for occupancy within 180 working
days from the  happening  thereof,  then,  at the option of  Landlord  or Tenant
exercised  in writing to the other  within 30 days of such  determination,  this
Lease shall  terminate  as of the  occurrence  of such  damage.  In the event of
termination,  Tenant  shall  pay Rent  duly  apportioned  up to the time of such
casualty and forthwith surrender the Premises and all interest.  If Tenant fails
to do so,  Landlord may reenter and take  possession  of the Premises and remove
Tenant.  If, however,  the damage is such that the architect  certifies that the
Premises can be made tenantable  within such 180-day period or neither  Landlord
or Tenant elects to terminate  the Lease despite the extent of damage,  then the
provisions below apply.

     18.4 If the  Premises are damaged by fire or other  casualty  that does not
render it wholly untenantable and require a repair period in excess of 180 days,
Landlord shall with reasonable  promptness  except as hereafter  provided repair
the Premises up to the level of the Initial Tenant Finish.

     18.5 If the Parking Garage or portions of the Building Complex required for
support or operation of the Building is damaged  (though the Premises may not be
affected, or if affected, can be repaired within 180 days) and within 30 days of
said  casualty  (or such  longer  period,  not to exceed a total of 45 days,  if
Landlord  is unable to obtain  such  certification  within the 30 day period for
causes beyond Landlord's reasonable control) Landlord decides not to reconstruct
or rebuild the Building,  then,  notwithstanding anything contained herein, upon
notice to that effect from  Landlord  within said  period,  Tenant shall pay the
Rent apportioned to the later of such casualty or the date that Tenant ceases to
use the Premises,  this Lease shall terminate from the date of such notice,  and
both parties discharged from further  obligations except as otherwise  expressly
provided.

     18.6 Landlord and Tenant waive all rights of recovery against the other and
its  respective  officers,  partners,  members,  agents,  representatives,   and
employees  for loss or  damage  to its real and  personal  property  kept in the
Building  Complex  which is capable of being  insured  against under ISO Special
Form Coverage,  or for loss of business  revenue or extra expense arising out of
or related to the use and occupancy of the Premises. Tenant also waives all such
rights of recovery  against  Building  Manager and Building  Manager  waives all
rights to recovery against Tenant. Each party shall, upon obtaining the property
damage insurance  required by this Lease,  notify the insurance carrier that the
foregoing waiver is contained in this Lease and use reasonable efforts to obtain
an appropriate waiver of subrogation provision in the policies.

     18.7 Rent shall  abate from the later of the date of such  casualty  or the
date that Tenant  ceases to use the Premises and  continuing  until  substantial
completion  during any period of repair and  restoration  up to the level of the
Initial Tenant Finish permitting  occupancy by Tenant,  any recovery by Landlord
under its loss of rent insurance  related to the Premises in the same proportion
that  the  part  of the  Premises  rendered  untenantable  bears  to the  whole;
provided,  however,  if the casualty is the fault of Tenant or Tenant's  agents,
then the Rent will abate  during any such period of repair and  restoration  but
only to the  extent of any  recovery  by  Landlord  under its  rental  insurance
related to the Premises.

     19. CONDEMNATION. If the Premises or substantially all of it or any portion
of the Building  Complex  which  renders the Premises  untenantable  is taken by
right of eminent domain, or by condemnation (which includes a conveyance in lieu
of a taking),  this Lease, at the option of either Landlord or Tenant  exercised
by notice to the other within 30 days after the taking, shall terminate and Rent
shall  be  apportioned  as of the date of the  taking.  Tenant  shall  forthwith
surrender  the Premises and all interest in this Lease,  and, if Tenant fails to
do so, Landlord may reenter and take


                                       13
<PAGE>

possession  of the  Premises.  If less than all the Premises is taken,  Landlord
shall  promptly  repair the  Premises  as nearly as  possible  to its  condition
immediately  prior to the taking,  unless  Landlord  elects not to rebuild under
Section 18.5.  Landlord shall receive the entire award or consideration  for the
taking,  except with respect to the value of Tenant's  improvements and fixtures
and for any separate award made to Tenant for its relocation  expenses  pursuant
to a  separate  independent  action  taken  by  Tenant  against  the  condemning
authority.

     20. DEFAULT BY TENANT.

     20.1 Each of the following events is an "Event of Default":

     (1) Any failure by Tenant to pay Rent on the due date  unless such  failure
is cured within 5 business days after notice by Landlord; however, Tenant is not
entitled to more than 2 notices of delinquent  payments during any calendar year
and, if  thereafter  during such calendar year any Rent is not paid when due, an
Event of Default shall automatically occur;

     (2) Tenant  vacates  (other than  temporary  vacation  during  which period
Tenant is engaged in trying to relet the  Premises) or abandons the Premises (as
evidenced by vacating the Premises  with the intent by Tenant not to be bound by
the terms of the Lease, as evidenced by a breach of any of its other obligations
under the Lease, including the payment of Rent);

     (3) This Lease or Tenant's interest is transferred  whether  voluntarily or
by operation of law except as permitted in Section 14;

     (4) This  Lease  or any part of the  Premises  is taken by  process  of law
against Tenant and is not released within 15 days after a levy;

     (5)  Commencement by Tenant of a proceeding  under any provision of federal
or state law relating to insolvency,  bankruptcy, or reorganization ("Bankruptcy
Proceeding");

     (6)  Commencement  of  a  Bankruptcy   Proceeding  against  Tenant,  unless
dismissed within 60 days after commencement;

     (7) The  insolvency of Tenant or execution by Tenant of an  assignment  for
the benefit of creditors; or the failure of Tenant generally to pay its debts as
they  mature,  or the  occurrence  of any of the  foregoing  with respect to any
Guarantor, if any, of Tenant's obligations;

     (8) The admission in writing by Tenant (or any general partner of Tenant if
Tenant is a  partnership),  that it is unable to pay its debts as they mature or
it is generally not paying its debts as they mature;

     (9)  Tenant  fails  to take  possession  of the  Premises  by the  90th day
following the Commencement Date (which deadline may be extended by delays beyond
the reasonable  control of Tenant,  provided that Tenant is proceeding  with due
diligence to complete the Finish Work and move into the Premises);

     (10)   Tenant   fails  to  perform  any  of  its  other   obligations   and
non-performance  continues  for 30 days  after  notice by  Landlord  or, if such
performance cannot be reasonably had within such 30 day period,  Tenant does not
in good faith  commence  performance  within  such 30 day period and  diligently
proceed  to  completion;  provided,  however,  that if  Tenant's  failure  would
constitute a violation of Applicable  Law and Landlord would be subject to fines
or penalties or use of the Building Complex by another tenant would be adversely
affected,  Tenant's  right to cure  shall not  exceed  the  period  provided  by
Applicable Law;


                                       14
<PAGE>

     (11) Any event which is expressly  defined as or deemed an Event of Default
under Sections 9 and 27.22 of this Lease.

     20.2 Remedies of Landlord. If an Event of Default occurs, Landlord may then
or at any time thereafter, either:

     (1) (a) Without  further  notice  except as required  by  Applicable  Laws,
reenter  and  repossess  the  Premises  or any part and expel  Tenant  and those
claiming  through or under Tenant and remove the effects of both  without  being
deemed  guilty of any manner of trespass  and without  prejudice to any remedies
for arrears of Rent or preceding  breach of this Lease.  Should Landlord reenter
or take possession  pursuant to legal  proceedings or any notice provided for by
Applicable Law, Landlord may, from time to time, without terminating this Lease,
relet the  Premises  or any part,  either  alone or in  conjunction  with  other
portions of the Building  Complex,  in  Landlord's  or Tenant's name but for the
account  of  Tenant,  for such  periods  (which  may be greater or less than the
period which would  otherwise have  constituted  the balance of the Term) and on
such conditions and upon such other terms (which may include concessions of free
rent and alteration  and repair of the Premises) as Landlord,  in its reasonable
discretion,  determines and Landlord may collect the rents therefor. Landlord is
not in any way  responsible or liable for failure to relet the Premises,  or any
part  thereof,  or for any failure to collect any rent due upon such  reletting,
but Landlord shall use commercially  reasonable efforts to mitigate its damages.
If there is other  unleased  space in the Worldgate  complex  (consisting of the
Building,  Plaza I and  building  that  may be built  on the  property  known as
Worldgate Parcel 12; collectively,  the "Worldgate Complex"), Landlord may lease
such other space  without  prejudice to its  remedies  against  Tenant.  No such
reentry  or  repossession  or notice  from  Landlord  shall be  construed  as an
election by Landlord to  terminate  this Lease  unless  specific  notice of such
intention is given Tenant.  Acts of  maintenance or  preservation  or efforts to
relet the Premises or the  appointment of a receiver upon initiative of Landlord
to  protect  Landlord's  interest  under  this  Lease  shall  not  constitute  a
termination of Tenant's  contractual  liability  under this Lease unless written
release of liability is given by Landlord to Tenant. Landlord reserves the right
following any reentry  and/or  reletting to exercise its right to terminate this
Lease by giving  Tenant  notice,  in which  event this Lease will  terminate  as
specified in the notice.

     (b) If Landlord takes possession of the Premises  without  terminating this
Lease,  Tenant  shall  pay  Landlord  (i) the Rent  which  would be  payable  if
repossession  had not  occurred,  less  (ii) the net  proceeds,  if any,  of any
reletting of the Premises after deducting all of Landlord's expenses incurred in
connection with such  reletting,  including all reasonable  repossession  costs,
brokerage commissions,  attorneys' fees, expenses of employees,  alteration, and
repair costs  (collectively  "Reletting  Expenses").  If, in connection with any
reletting,  the new lease term extends  beyond the Term or the premises  covered
thereby include other premises not part of the Premises, a fair apportionment of
the rent received from such reletting and the Reletting  Expenses,  will be made
in determining the net proceeds received from the reletting. In determining such
net proceeds, rent concessions will also be apportioned over the term of the new
lease.  Tenant shall pay such  amounts to Landlord  monthly on the days on which
the Rent  would  have been  payable  if  possession  had not been  retaken,  and
Landlord is entitled to receive the same from Tenant on each such day; or

     (2) Give Tenant notice of  termination  of this Lease on the date specified
and, on such date,  Tenant's right to possession of the Premises shall cease and
the Lease will terminate except as to Tenant's  liability as hereafter  provided
as if the  expiration of the term fixed in such notice were the end of the Term.
If this Lease  terminates  pursuant to this Section,  Tenant  remains  liable to
Landlord  for damages in an amount equal to the Rent which would have been owing
by Tenant for the  balance of the Term had this Lease not  terminated,  less the
net  proceeds,  if any, of reletting of the Premises by Landlord  subsequent  to
termination  after  deducting  Reletting  Expenses.  Landlord  may collect  such
damages  from  Tenant  monthly  on the days on which  the Rent  would  have been
payable if this Lease had not  terminated  and  Landlord  shall be  entitled  to
receive the same from Tenant on each such day.  Alternatively,  if this Lease is
terminated,  Landlord  at its option may  recover  forthwith  against  Tenant as
damages  for loss of the  bargain  and not as a penalty  an amount  equal to the
worth at the time of termination of the excess,  if any, of the Rent reserved in
this Lease for the balance of the Term over the then Reasonable  Rental Value of
the Premises for the same period plus all Reletting Expenses. "Reasonable Rental
Value" is the amount of rent  Landlord can obtain for the  remaining  balance of
the Term.

     20.3 Cumulative Remedies.  Suits to recover Rent and damages may be brought
by Landlord,  from time to time, and nothing herein  requires  Landlord to await
the  date  the  Term  would  expire  had  there  been no  Event  of  Default  or
termination,  as the case may be.  Each  right and remedy  provided  for in this
Lease is cumulative  and  non-exclusive  and in addition to every other right or
remedy  now or  hereafter  existing  at  law  or  equity,  including  suits  for
injunctive  relief and  specific  performance.  The exercise or beginning of the
exercise by Landlord of one or more rights or remedies  shall not  preclude  the
simultaneous  or later  exercise by Landlord of other  rights or  remedies.  All
costs  incurred by  Landlord to collect any Rent and damages or to enforce  this
Lease are also  recoverable  from Tenant.  If any suit is brought  because of an
alleged breach of this Lease,  the prevailing  party is also entitled to recover
from the other  party all  reasonable  attorneys'  fees and  costs  incurred  in
connection therewith.

     20.4 No Waiver. No failure by Landlord to insist upon strict performance of
any provision or to exercise any right or remedy upon a breach  thereof,  and no
acceptance  of full  or  partial  Rent  during  the  continuance  of any  breach
constitutes  a waiver of any such  breach or such  provision,  except by written
instrument executed by Landlord.  No waiver shall affect or alter this Lease but
each  provision  hereof  continues  in effect  with  respect  to any other  then
existing or subsequent breach thereof.

     20.5 Bankruptcy. Nothing contained in this Lease limits Landlord's right to
obtain as liquidated damages in any bankruptcy or similar proceeding the maximum
amount  allowed by law at the time such  damages are to be proven,  whether such
amount is  greater,  equal to, or less than the amounts  recoverable,  either as
damages or Rent, referred to in any of the preceding provisions of this Section.
Notwithstanding  anything  in  this  Section  to the  contrary,  any  proceeding
described  in Section  20.1(5),(6),(7)  and (8) is an Event of Default only when
such proceeding is brought by or against the then holder of the leasehold estate
under this Lease.

     20.6 Late Payment  Charge.  Any Rent not paid within 5 business  days after
the due date shall  thereafter  bear  interest at 5 percentage  points above the
Prime Rate or the highest rate permitted by law, whichever is lower, until paid.
Further,  if such Rent is not paid within 5 business days after  notice,  Tenant
agrees Landlord will incur  additional  administrative  expenses,  the amount of
which will be difficult to determine; Tenant therefore shall also pay Landlord a
late charge for each late  payment of 5% of such  payment.  Any amounts  paid by
Landlord to cure a default of Tenant  which  Landlord  has the right but not the
obligation  to do,  shall,  if not  repaid by Tenant  within 5 days of demand by
Landlord,  thereafter bear interest at 5 percentage  points above the Prime Rate
until paid.  "Prime Rate" means that rate announced by Wells Fargo Bank, N.A. as
its prime rate on the date closest to the date interest commences.

     20.7 Waiver of Jury Trial.  Tenant and Landlord  waive any right to a trial
by jury in suits arising out of or concerning the provisions of this Lease.

     20.8 Self-Help.  Notwithstanding anything in the Lease to the contrary, the
use of force by Landlord or its agents shall not be included  among the remedies
available  to  Landlord.  Landlord  reserves  the right to use  other  self-help
remedies provided that they do not disturb the peace.

     21. DEFAULT BY LANDLORD. In the event of any alleged default on the part of
Landlord,  Tenant shall give notice to Landlord and afford Landlord a reasonable
opportunity to cure such default,  provided  Landlord  commences such cure on or
before the Fifth (5th) day following Tenant's notice and diligently pursues such
cure to completion using commercially  reasonable efforts.  Such notice shall be
ineffective  unless  a copy  is  simultaneously  also  delivered  in the  manner
required  in this  Lease  to any  holder  of a  mortgage  and/or  deed of  trust
affecting   all  or  any  portion  of  the   Building   Complex   (collectively,
"Mortgagee"),  provided  that prior to such notice Tenant has been given written
notice in  accordance  with the notice  provisions of this Lease of the identity
and the address of such  Mortgagee.  Within  such Five (5) day period,  Landlord
shall  provide  written  notice to Tenant of  Landlord's  intended  actions  and
schedule for completion of such cure and regular progress reports  regarding the
same. If Landlord fails to cure such default in accordance with the requirements
set forth above or within 30 days following the notice to Landlord, whichever is
earlier,


                                       16
<PAGE>

then  Mortgagee  shall have an additional 30 days following a second notice from
Tenant or, if such  default  cannot be cured within that time,  such  additional
time as may be necessary to effect a cure,  provided  Mortgagee  commences  such
cure on or  before  the  Fifth  (5th)  day  following  such  second  notice  and
diligently pursues such cure to completion using commercially reasonable efforts
(which  pursuit  shall  include,  without  limitation,   commencing  foreclosure
proceedings  and  seeking  relief in any  applicable  bankruptcy  or  insolvency
proceedings, if necessary to effect such cure). If Landlord fails to cure within
Landlord's cure period,  Tenant shall be entitled to relief against Landlord for
such  default  (other  than  termination  of  the  Lease)  for  so  long  as the
Mortgagee's cure period remains in effect.  If such default involves  Landlord's
failure to make repairs,  provide essential  services,  pay utility bills as are
required under this Lease or any other circumstance that would materially impair
Tenant's  ability to continue  operating  its business on and from the Premises,
then, if such default or failure is not cured within Five (5) days following the
date of such notice to Landlord, Tenant also shall have the right (but shall not
be  obligated  to) to  undertake  such repairs (in such manner as to not to void
applicable  warranties),  provide  services or pay such bills or take such other
actions as are  reasonably  required  to enable  Tenant to avoid  such  material
impairment  and to continue  operating  its business  activities on and from the
Premises  (consistent  with the Permitted Uses under this Lease),  provided that
such  undertakings  by Tenant do not  materially  interfere with such actions by
Landlord to effect a cure as are (1) actually  being  undertaken  by Landlord at
such time and (2) as are equally likely and  expeditious in effecting a complete
cure as those  which  could be taken or are  proposed to be taken by Tenant and,
further provided,  that Tenant's  undertakings to effect a cure do not result in
any permanent  material  damage to the Building or Building  Complex.  As to all
such  undertakings by Tenant,  Landlord shall reimburse Tenant within 30 days of
receipt of Tenant's  invoice the full  amount of such  reasonable  out-of-pocket
costs and  expenses  incurred  by Tenant;  provided,  however,  that if Landlord
disputes  that such default  exists or disputes the  reasonableness  of all or a
portion of the amount to be paid, by notice to Tenant prior to the expiration of
the 30 day period,  then  Landlord  shall have no  obligation  to pay the amount
disputed  until  such  dispute is  determined  by final  decision  of a court or
agreement  of the parties.  If any such repairs will affect the HVAC,  plumbing,
electrical or mechanical  systems of the Building (the "Building Systems "), the
structural  integrity  of  the  Building,  or  the  exterior  appearance  of the
Building,  Tenant  shall use only  those  contractors  used by  Landlord  in the
Building for work on the  Building  Systems,  or its  structure,  provided  that
Landlord  provides Tenant (upon Tenant's  request) with notice  identifying such
contractors  and  any  changes  to the  list of such  contractors,  unless  such
contractors  are  unwilling  or unable to perform  such work or the cost of such
work is not  competitive,  in which event Tenant may utilize the services of any
other qualified  contractors which normally and regularly  performs similar work
on  comparable  buildings.  To the extent any sum thus  reimbursed  to Tenant by
Landlord  represents  an amount that would have been  included in the  Operating
Expenses  of the  Building if paid by  Landlord  to perform  the  obligation  in
question,  Landlord  shall be entitled to include in Operating  Expenses the sum
reimbursed to Tenant.  Tenant's sole additional  remedy will be equitable relief
or actual damages but in no event is Landlord or any Mortgagee  responsible  for
consequential  damages  or lost  profit  incurred  by  Tenant as a result of any
default  by  Landlord.  If  a  Mortgagee,  or  transferee  under  such  Mortgage
(hereafter defined),  succeeds to Landlord's interest as a result of foreclosure
or otherwise,  such party shall not be: (i) liable for any default,  nor subject
to any setoff or defenses  that Tenant may have  against  Landlord  except for a
reimbursement  obligation  arising under this Section as to which such Mortgagee
has been given  notice and the  opportunity  to  dispute as  provided  herein or
except for  obligations  arising or continuing  after the date such Mortgagee or
transferee  succeeds  to  Landlord's  interest;  (ii)  bound  by  any  amendment
(including an agreement for early  termination)  without its consent made at any
time after notice to Tenant that such Mortgage requires such consent;  and (iii)
bound by payment of Rent in advance for more than 30 days.  Tenant agrees to pay
Rent (and will receive  credit under this Lease) as directed in any  Mortgagee's
notice of  Landlord's  default  under the Mortgage  reciting  that  Mortgagee is
entitled to collect Rent.  The terms of Section 7 of this Lease shall be subject
to the terms of this Section.

     22. SUBORDINATION AND ATTORNMENT.

     22.1 This Lease at Landlord's  option will be  subordinate to any mortgage,
deed of trust and related  documents  now or hereafter  placed upon the Building
Complex  (including  all  advances  made  thereunder),  and to  all  amendments,
renewals,  replacements,  or restatements  thereof  (collectively,  "Mortgage").
Tenant  agrees  that no  documentation  other  than this  Lease is  required  to
evidence such subordination, provided, however, that the subordination by Tenant
to any such future mortgage, deed of trust or related documents shall be subject
to Tenant obtaining a non-


                                       17
<PAGE>

disturbance  agreement,  on such lender's standard form agreement,  with changes
are Tenant may  reasonably  require (to the extent such  changes are  consistent
with  provisions  in forms  customarily  executed  by  credit-worthy  full-floor
tenants)  whereby  such lender  agrees,  provided  Tenant is not then in default
under  this  Lease,  that  Tenant's  occupancy  of the  Premises  and rights and
privileges  under this Lease shall not be  disturbed  or impaired in  connection
with any proceeding to enforce or foreclose any such mortgage,  trust  indenture
or other lien and if such party  succeeds to the interests of Landlord by reason
of such proceedings or conveyance in lieu thereof, Tenant shall attorn hereunder
directly to such party;  provided,  however,  such party shall not be (i) liable
for any act or omission of any prior  landlord or (ii) subject to any offsets or
defenses which Tenant might have against any prior landlord,  including Landlord
(but such  limitation  shall not relieve such party from the  responsibility  to
perform the obligations as successor to Landlord applicable during its period of
ownership);  or (iii) bound by any rental  which Tenant might have paid for more
than one (1)  month in  advance  to any  prior  landlord;  or (iv)  bound by any
amendment or modification of the Lease made without its consent.

     22.2 If any Mortgagee elects to have this Lease superior to the lien of its
Mortgage  and gives  notice to Tenant,  this Lease will be deemed  prior to such
Mortgage  whether  this Lease is dated prior or  subsequent  to the date of such
Mortgage or the date of recording thereof.

     22.3 In confirmation of subordination or superior position, as the case may
be, Tenant will execute such documents as may be required by Mortgagee and if it
fails to do so within 10 days after demand,  Tenant hereby irrevocably  appoints
Landlord as Tenant's attorney-in-fact and in Tenant's name, place, and stead, to
do so.

     22.4 Tenant hereby attorns to all successor owners of the Building, whether
such ownership is acquired by sale, foreclosure of a Mortgage, or otherwise.

     22.5 Upon the  execution  hereof,  Tenant and  Landlord's  Mortgagee  shall
execute the form of  nondisturbance  agreement  in the form  attached  hereto as
EXHIBIT J and thereafter Landlord promptly shall provide Tenant such document as
executed by Landlord's Mortgagee.

     23. REMOVAL OF TENANT'S PROPERTY.

     23.1 All movable personal  property of Tenant not removed from the Premises
upon vacation,  abandonment,  or termination of this Lease shall be conclusively
deemed  abandoned and may be sold, or otherwise  disposed of by Landlord without
notice to Tenant and without obligation to account;  Tenant shall pay Landlord's
expenses in connection with such disposition.

     23.2 Tenant shall have the right to collaterally  assign Tenant's  interest
in its furniture,  fixtures,  and equipment that are not considered  part of the
Premises; Landlord agrees to execute documents, subject to Landlord's reasonable
approval,  evidencing  that Landlord does not have a  pre-existing  lien on such
personal property.

     24.  HOLDING  OVER:  TENANCY  MONTH-TO-MONTH.  If, after the  expiration or
termination of this Lease,  Tenant remains in possession of the Premises without
a  written  agreement  as to such  holding  over and  continues  to pay rent and
Landlord  accepts such rent, such  possession is a tenancy from  month-to-month,
subject to all provisions hereof but at a monthly rent equivalent to 150% of the
monthly Rent paid by Tenant immediately prior to such expiration or termination.
Rent shall  continue to be payable in advance on the first day of each  calendar
month. Such tenancy may be terminated by either party upon 10 days' notice prior
to the end of any monthly period. Nothing contained herein obligates Landlord to
accept rent tendered after the expiration of the Term or relieves  Tenant of its
liability under Section 17.

     25. PAYMENTS AFTER  TERMINATION.  No payments by Tenant after expiration or
termination  of this Lease or after any notice  (other than a demand for payment
of money) by  Landlord to Tenant  reinstates,  continues,  extends the Term,  or
affects  any  notice  given to  Tenant  prior to such  payments.  After  notice,
commencement of a suit, or


                                       18
<PAGE>

final  judgment  granting  Landlord  possession  of the  Premises,  Landlord may
collect  any amounts  due or  otherwise  exercise  Landlord's  remedies  without
waiving any notice or affecting any suit or judgment.

     26.  STATEMENT OF  PERFORMANCE.  Tenant and Landlord agree at any time upon
not less than 10  business  days'  written  notice to execute and deliver to the
requesting  party a written  statement  certifying that this Lease is unmodified
and in full force and effect  (or,  if there have been  modifications,  that the
same is in full force and effect as modified  stating the  modifications);  that
there have been no  defaults  by  Landlord or Tenant and no event which with the
giving of notice or passage of time, or both,  would  constitute  such a default
(or, if there have been defaults, setting forth the nature thereof); the date to
which Rent has been paid in advance and such other  information  relating to the
Lease as the requesting party requests. Such statement from Tenant may be relied
upon by a prospective purchaser of Landlord's interest or Mortgagee. The failure
of either party when  requested to timely  deliver such  statement is conclusive
upon the failing party that:  (i) this Lease is in full force and effect without
modification  except as may be represented by the requesting  party;  (ii) there
are no uncured  defaults in the requesting  party's  performance;  and (iii) not
more than 1 month's Rent has been paid in advance.  Upon request, the certifying
party will furnish Landlord an appropriate certificate confirming that the party
signing the statement is authorized to do so.

     27. MISCELLANEOUS.

     27.1 Transfer by Landlord.  The term "Landlord" means so far as obligations
of  Landlord  are  concerned,  only  the  owner of the  Building  at the time in
question and, if any transfer of the title occurs, Landlord herein named (and in
the  case of any  subsequent  transfers,  the  then  grantor)  is  automatically
released  from and after the date of such  transfer of all liability as respects
performance of any obligations of Landlord thereafter to be performed. Any funds
in Landlord's possession at the time of transfer in which Tenant has an interest
will be turned over to the  grantee  and any amount  then due Tenant  under this
Lease will be paid to Tenant.

     27.2 No Merger.  The termination or mutual  cancellation of this Lease will
not work a merger,  and such  termination or cancellation  will at the option of
Landlord either terminate all subleases or operate as an automatic assignment to
Landlord of such subleases.

     27.3  Common  Area Use.  Landlord  may use any of the Common  Areas for the
purposes of completing or making  repairs or  alterations  in any portion of the
Building Complex, subject to the provisions of Section 11.

     27.4  Independent  Covenants.  This Lease is to be  construed as though the
covenants  between  Landlord and Tenant are  independent  and not  dependent and
Tenant is not  entitled to any setoff of the Rent  against  Landlord if Landlord
fails to perform its  obligations;  provided,  however,  the foregoing  does not
impair  Tenant's  right to commence a separate  suit  against  Landlord  for any
default by Landlord so long as Tenant complies with Section 21.

     27.5 Validity of  Provisions.  If any provision is invalid under present or
future laws,  then it is agreed that the remainder of this Lease is not affected
and that in lieu of each provision that is invalid,  there will be added as part
of this  Lease a  provision  as  similar  to such  invalid  provision  as may be
possible and is valid and enforceable.

     27.6 Captions.  The caption of each Section is added for  convenience  only
and has no effect in the construction of any provision of this Lease.

     27.7  Construction.  The  parties  waive  any  rule  of  construction  that
ambiguities are to be resolved  against the drafting party.  Any words following
the words "include,"  "including," "such as," "for example," or similar words or
phrases shall be illustrative only and are not intended to be exclusive, whether
or not language of non-limitation is used.


                                       19
<PAGE>

     27.8 Applicability.  Except as otherwise  provided,  the provisions of this
Lease are  applicable  to and binding upon  Landlord's  and Tenant's  respective
heirs,  successors  and  assigns.  Such  provisions  are also  considered  to be
covenants running with the land to the fullest extent permitted by law.

     27.9  Authority.  Tenant  and the party  executing  this Lease on behalf of
Tenant represent to Landlord that such party is authorized to do so by requisite
action of Tenant and agree,  upon  request,  to deliver  Landlord a  resolution,
similar document, or opinion of counsel to that effect.

     27.10  Severability.  If there is more than one party  which is the Tenant,
the obligations imposed upon Tenant are joint and several.

     27.11  Acceptance  of Keys,  Rent or  Surrender.  No act of Landlord or its
representatives  during the Term,  including any agreement to accept a surrender
of the Premises or amend this Lease,  is binding on Landlord  unless such act is
by a partner,  member or officer of Landlord, as the case may be, or other party
designated  in writing by Landlord as authorized to act. The delivery of keys to
Landlord or its representatives  will not operate as a termination of this Lease
or a surrender of the Premises. No payment by Tenant of a lesser amount than the
entire  Rent owing is other than on account of such Rent nor is any  endorsement
or  statement  on any  check  or  letter  accompanying  payment  an  accord  and
satisfaction.  Landlord may accept payment without prejudice to Landlord's right
to recover the balance or pursue any other remedy available to Landlord.

     27.12 Building Name and Size.  Landlord may change the name of the Building
and as it relates to the Building  Complex other than the  Building:  change the
name,  increase the size by adding  additional  real property,  construct  other
buildings  or  improvements,  change  the  location  and/or  character,  or make
alterations  or  additions  subject  to  the  provisions  of  Section  11.1.  If
additional  buildings are  constructed  or the size is  increased,  Landlord and
Tenant shall execute an amendment that incorporates any necessary  modifications
to  Tenant's  Pro Rata  Share.  Tenant may not use the  Building's  name for any
purpose other than as part of its business address.

     27.13 Diminution of View.  Tenant agrees that no diminution of light,  air,
or view from the Building  entitles  Tenant to any  reduction of Rent under this
Lease,  results in any  liability  of Landlord,  or in any way affects  Tenant's
obligations.

     27.14  Limitation  of Liability.  Notwithstanding  anything to the contrary
contained in this Lease,  Landlord's liability is limited to Landlord's interest
in the Building and Landlord  shall never be  personally  liable for recovery of
any judgment.

     27.15  Non-Reliance.  Tenant  confirms it has not relied on any statements,
representations,  or warranties by Landlord or its representatives except as set
forth herein.

     27.16 Written  Modification.  No amendment or modification of this Lease is
valid or binding unless in writing and executed by the parties.

     27.17 Lender's  Requirements.  Tenant will make such  modifications to this
Lease as may  hereafter  be  required  to  conform  to any  lender's  reasonable
requirements, so long as such modifications do not increase Tenant's obligations
or materially alter its rights, as reasonably determined by Tenant.

     27.18  Effectiveness.  Submission of this  instrument  for  examination  or
signature by Tenant does not  constitute a reservation of or option to lease and
it is not effective unless and until execution and delivery by both Landlord and
Tenant.


                                       20
<PAGE>

     27.19  Survival.  This Lease,  notwithstanding  expiration or  termination,
continues in effect as to any  provisions  requiring  observance or  performance
subsequent to termination or expiration.

     27.20 Time of Essence. Time is of the essence herein.

     27.21 Rules and Regulations.  If rules and regulations are attached hereto,
they are a part of this Lease and Tenant agrees that Tenant and Tenant's  Agents
shall at all times abide by such rules and regulations.

     27.22 Recording.  Tenant will not record this Lease. Recording of the Lease
by or on behalf of Tenant is an Event of Default.

     27.23 Consent.  Where either  party's  consent is required under the Lease,
such consent shall not be unreasonably withheld, delayed or conditioned,  except
as expressly provided.

     28. AUTHORITIES FOR ACTION AND NOTICE.

     28.1  Unless  otherwise  provided,  Landlord  may  act  through  Landlord's
Building Manager or other designated representatives from time to time.

     28.2 All notices or other communications required or desired to be given to
Landlord must be in writing, addressed as set forth in Section 1.10 and shall be
deemed  received  when:  (i) delivered  personally to any officer,  partner,  or
member of Landlord (depending upon the nature of Landlord) or the manager of the
Building (the "Building  Manager")  whose office is in the Building,  or (ii) if
deposited in the United States mail,  postage prepaid,  certified or registered,
return receipt requested, when such notice is received or receipt is refused, or
(iii) if  deposited  with a  nationally  recognized  courier  service  providing
confirmation of receipt,  when such notice is received or receipt is refused, or
(iv) if sent by facsimile  transmission,  when received and oral confirmation by
telephone  of such  receipt  has been  given by the  recipient.  All  notices or
communications  required  or desired to be given to Tenant  must be in  writing,
addressed  as set  forth in  Section  1.13 and shall be  deemed  received  when:
(i) delivered  personally  to  any  officer,  partner,  or  member  of  Landlord
(depending  upon the nature of  Landlord)  or the manager of the  Building  (the
"Building Manager") whose office is in the Building, or (ii) if deposited in the
United States mail,  postage  prepaid,  certified or registered,  return receipt
requested,  when such  notice is  received  or receipt is  refused,  or (iii) if
deposited with a nationally recognized courier service providing confirmation of
receipt,  when such notice is received or receipt is refused, or (iv) if sent by
facsimile transmission, when received and oral confirmation by telephone of such
receipt has been given by the  recipient.  Either party may designate in writing
served as above  provided a different  address to which  notice is to be mailed.
The foregoing does not prohibit notice from being given as provided in the rules
of civil  procedure,  as amended  from time to time,  for the state in which the
Real Property is located.

     29.  PARKING.  Landlord  shall  control  parking in the  Parking  Garage by
Tenant's  employees  and employees of tenants in Plaza II by issuance of parking
passes;  Landlord will make  available the number of parking spaces set forth in
Section 1.9 without  charge for parking by Tenant's  employees by issuing passes
to employees designated by Tenant for the applicable number of spaces.  Landlord
shall have the right to control or limit  parking by visitors to the Building in
a manner  consistent  with  policies  at similar  first-class  buildings  in the
suburban  northern  Virginia area; the visitor spaces for Tenant shall be in the
surface spaces adjacent to the entry to the Building,  as shown on the site plan
attached  as  EXHIBIT  H (which  spaces  shall be a  portion  of the 322  spaces
allocated to Tenant in  accordance  with Section 1.9)  designated  by signage as
visitor  parking  spaces for Tenant's  visitors only (but Landlord shall have no
obligation  to police the use of such visitor  spaces);  the  remaining  parking
spaces  shall be in the  parking  garage  located in the lower level and the 1st
through 4th floors of the  Building  and of the Plaza I Building  (the  "Parking
Garage") and in surface  parking  spaces in the Building  Complex as depicted on
the  attached  EXHIBIT  H.  All  Tenant's  parking  spaces  shall be in and out,
non-assigned,  however, at Tenant's request, Landlord shall label by signage all
spaces  allocated to Tenant (other than  handicapped  spaces) as depicted on the
attached  EXHIBIT H and Tenant  shall have the right to  install  control  gates
limiting


                                       21
<PAGE>

access to Tenant's  parking  spaces on parking level four (subject to Landlord's
reasonable  approval  of such system and  subject to the  provisions  of Section
7.1);  the costs of such  signage  and  control  gates  shall be paid by Tenant.
Notwithstanding the above, Landlord's inability to make such spaces available at
any time for  reasons  beyond  Landlord's  reasonable  control is not a material
breach by Landlord of its obligations  hereunder and Tenant has no rights to use
the parking garage except as provided in this Section.  If Landlord is unable to
make all such spaces available for reasons beyond Landlord's reasonable control,
Landlord  shall  take  reasonable  steps to make all such  spaces  available  as
provided herein.  All vehicles parked in the parking facilities and the personal
property  therein shall be at the sole risk of Tenant,  Tenant's  Agents and the
users of such spaces and  Landlord  shall have no  liability  for loss or damage
thereto for whatever cause.

     30. SUBSTITUTE PREMISES. INTENTIONALLY OMITTED.

     31.  BROKERAGE.  Tenant  represents  it has not  employed  any broker  with

                                    ADDENDUM

     THIS  ADDENDUM is to that  certain  lease  agreement  (the  "Lease") by and
between WGP ASSOCIATES,  LLC, a Virginia limited liability company ("Landlord"),
and SAVVIS COMMUNICATIONS  CORPORATION, a Missouri corporation ("Tenant"),  with
respect to  approximately  80,580 rentable square feet of space (the "Premises")
in the Building.  In the event of any conflict  between the terms and provisions
of the  Lease  and the  terms and  provisions  of this  Addendum,  the terms and
provisions of this Addendum shall control.

     1. Landlord  grants  Tenant an option (the  "Option") to extend the term of
the Lease for one (1) additional term of five (5) years (the "Option Term"). The
Option applies only to the Premises and is on the following conditions:

     A. Notice of Tenant's  interest in  exercising  the Option must be given to
Landlord  no  earlier  than 12 months  and no later  than 9 months  prior to the
Expiration  Date  ("Tenant's  Notice").  Not later than  thirty  (30) days after
receiving  Tenant's  Notice,  Landlord  will  notify  Tenant  of the  Base  Rent
applicable  during the  Option  Term in  accordance  with  subparagraph  E below
("Landlord's Notice").

     B.  Tenant  shall have 15 days  following  Tenant's  receipt of  Landlord's
Notice  within  which to exercise  the Option for the Option Term by  delivering
written  notice of such  exercise to Landlord at the Base Rent,  allowances  and
concessions, if any, set forth in Landlord's Notice or delivering notice of such
exercise but reserving the right to final  determination  of the Base Rent to be
paid in accordance with  subparagraphs E below ("Tenant's  Dispute Notice").  If
Tenant timely  exercises the Option for the  respective  Option Term,  the Lease
shall be deemed  extended and  thereafter the parties shall execute an amendment
to the Lease setting forth the extension for the Option Term and the rental rate
applicable  upon  determination  of the Base Rent  applicable in accordance with
subparagraph E below.

     C.  Unless  Landlord  is  timely  notified  by Tenant  in  accordance  with
subparagraphs A and B above, it will be conclusively  deemed that Tenant has not
exercised the Option and the Lease will expire in  accordance  with its terms on
the Expiration Date.

     D. Tenant's  rights  pursuant to this  Paragraph are personal to Tenant and
may not be assigned.  Tenant's right to exercise the Option is  conditioned  on:
(i)  Tenant  not  being in  default  at the time of  exercise  or at the time of
commencement  of the Option  Term;  (ii) Tenant not having  subleased or vacated
more than 33% of the Premises or assigned its interest under the Lease as of the
commencement  of the Option Term; and (iii) Tenant having the financial  ability
to perform its  obligations  under the Option Term.  Upon an  assignment  of the
Lease, this Paragraph is null and void.

     E. Following delivery of Tenant's Dispute Notice, Landlord and Tenant shall
promptly initiate  negotiations to determine a mutually acceptable Base Rent. If
the parties  mutually agree upon a Base Rent rate, such agreed rate shall be the
Base Rent rate applicable during the Option Term. If the parties have not agreed
upon the  terms as of the 20th day after the date of  Tenant's  Dispute  Notice,
then Landlord and Tenant shall,  within thirty (30) days after Tenant's delivery
of Tenant's Dispute Notice, agree upon a qualified commercial real estate broker
of good reputation,  having at least five (5) years'  experience in the northern
Virginia  real estate  market;  if  Landlord  and Tenant  cannot  agree upon the
broker, then they shall each select,  within the foregoing  thirty-day period, a
real estate broker who meets the above  qualifications and together such brokers
will then  select as the  arbitrator  a real  estate  broker who meets the above
qualifications (the broker selected shall be deemed the "Arbitrator" hereunder).
Within ten (10)) days of selection of the  Arbitrator,  Landlord and Tenant each
shall state, in writing,  their  determination  of the Prevailing  Market Rental
Rate  supported by the reasons  therefor and shall make  counterpart  copies for
each other and the Arbitrator, under an arrangement for simultaneous exchange of
the  determinations.  The Arbitrator will review each party's declaration of the
Prevailing  Market  Rental  Rate and  select  the one which he  determines  most
accurately  reflects such  Arbitrator's  determination of the Prevailing  Market
Rental Rate.  The  Arbitrator  shall have no right to propose a middle ground or
any


                                        1
<PAGE>

modifications of either of the two proposed  resolutions.  The Base Rent to paid
during the Option Term shall be the Prevailing  Market Rental Rate so determined
and Tenant shall have the right to receive the  allowance  and  concessions,  if
any, set forth in  Landlord's  Notice.  The costs  incurred in  connection  with
engaging the  Arbitrator  shall be shared  equally by Landlord  and Tenant,  and
shall be determined at the time the Arbitrator is selected. For purposes of this
Paragraph, Prevailing Market Rental Rate shall mean the annual amount per square
foot (including the then-current Operating Expenses) that a willing tenant would
pay and a willing landlord would accept following arms-length  negotiations with
respect to an "Assumed  Lease" (as defined below) under the  circumstances  then
obtaining.  "Assumed  Lease" means (i) a lease or renewal  having a commencement
date within 6 months of Tenant's Notice for space of approximately the same size
as the  Premises of the  Building or a  "Comparable  Building,"  as  hereinafter
defined,  located in a portion of the Building or such Comparable Building,  and
with a view and floor  height  similar to the portion of the  Premises for which
Prevailing Market Rental Rate is being determined, for a term equal in length to
the Option Term;  (ii)  assuming  that a real estate  commission is payable with
respect to such lease to the extent a  third-party  commission  with  respect to
extension is agreed or  obligated to be paid by Landlord;  and (iii) taking into
consideration  and making  adjustment  to  reflect  allowances  and  concessions
provided  in  Landlord's  Notice,  if any,  and the  use of the  Base  Operating
Expenses provided in Section 1.5 during the Option Term.  "Comparable  Building"
shall mean any existing building or building hereafter constructed in the Dulles
corridor of northern Virginia which is of a size, location, quality and prestige
comparable  to, and with a size and  efficiency of floor plate,  amenities,  and
with tenants of a stature reasonably comparable with the Building, provided that
appropriate  adjustments  shall be made to adjust for  differences  in the size,
location,  age,  efficiency  of  floorplate,  and  quality  between  such  other
buildings and the Building.

     F. After exercise,  or failure to exercise the Option, Tenant shall have no
further rights to extend the Term.

     2. In accordance with the Work Letter,  as part of the Finish Work,  Tenant
shall have the right to have signage  installed on a monument to be  constructed
by Landlord,  which  monument  shall be  constructed  at Landlord's  cost;  such
signage  shall be subject to  approval by  Landlord  of the exact  location  and
details,  which  approval  shall not be  unreasonably  withheld,  conditioned or
delayed.  Further,  the monument and Tenant's signage on the monument is subject
to  approval  under  Applicable  Law and under  the  declaration  of  protective
covenants  applicable  to the Real Property  (the  "Declaration"),  all of which
approvals shall be diligently pursued by Landlord. The monument,  which shall be
designed  and  constructed  by Landlord at  Landlord's  cost,  is intended for a
building  name/address  identifier for the entire 4 tower Worldgate Plaza I, II,
III,  and IV complex and for tenants of the  complex,  and  notwithstanding  the
above, is not exclusively for Tenant's signage;  however,  Tenant shall have the
right to use 25% of such monument  signage area;  the monument shall not be used
for Tenant's signage if only the Building  name/address  identifier is permitted
on such monument under the  Declaration  and  Applicable  Law. The costs for the
design,  fabrication and installation of such Tenant's signage shall be borne by
Tenant  (subject to the allowance  provisions  of the Work Letter).  Tenant will
bear the costs of removal of any signage at the termination or expiration of the
Lease,  including  restoring or repairing damages to the monument caused by such
removal to the condition at the time of installation.  In addition,  if Landlord
is required at any time to remove any signage,  including any approved  signage,
due to any Applicable Law or if Tenant elects to remove or change the signage at
any time, Tenant shall bear the costs of such change or removal.  Tenant will be
responsible  at its cost to maintain its signage in  reasonably  good  condition
acceptable  to Landlord at  Landlord's  reasonable  discretion;  Landlord  shall
maintain  the  monument  as part of the  Common  Areas and shall  require  other
tenants to maintain  their  respective  signage.  In  addition  to the  monument
signage, Tenant shall have the right to install a corporate  identification sign
on the exterior of the Building facing the Dulles  Toll/Access  Roads out of the
Allowance  or, if there is no balance of the  Allowance  available,  at Tenant's
expense.  Such  Building  signage shall be subject to approval  (including  with
respect to  location,  style,  size,  material,  and method of  application)  by
Landlord,  which approval  shall not be  unreasonably  withheld,  conditioned or
delayed,  and under  Applicable Laws and under the Declaration  (which approvals
shall be  diligently  pursued by  Landlord).  Tenant shall not  otherwise  affix
signage to the outside of the  Building  and no signage  shall be affixed to the
inside of the Building that is visible outside the Building without the approval
of Landlord,  which approval shall not be unreasonably  withheld or delayed. The
rights  granted to Tenant  pursuant to this Paragraph are personal to Tenant and
any assignees (except an assignee  permitted under Section 14.7 of the Lease) or


                                        2
<PAGE>

subtenants  of Tenant have no rights under this  Section.  Tenant shall have the
right to erect temporary construction  identification  signage, at Tenant's sole
cost and expense,  during the period prior to the Commencement  Date identifying
the Building as Tenant's future  location,  subject to approval  (including with
respect to  location,  style,  size,  material,  and method of  application)  by
Landlord  which  approval  shall not be  unreasonably  withheld,  conditioned or
delayed,  and approval under  Applicable Laws and under the  Declaration  (which
approvals shall be diligently pursued by Landlord).

     3.  During  the  Term,  Tenant  shall  have a right  to use the roof of the
Building for the purpose of installing,  maintaining and operating the following
described  equipment  on  a  portion  of  the  roof  of  the  Building  ("Roof")
anticipated  to be within the area  labeled  "(1)" on the roof plan  attached as
part of EXHIBIT I, with the actual  location to be  designated  by Landlord,  in
Landlord's reasonable discretion ("Roof Space"): (1) chillers, as referred to on
EXHIBIT 5 to the Work Letter, to service equipment in the Premises  ("Chillers")
and (2) non-penetrating (or alternative attachment methods approved by Landlord)
microwave/satellite  dishes,  not to exceed  approximately one meter in diameter
(or such  larger  dimensions  as shall be subject to  Landlord's  prior  written
consent, not to be unreasonably withheld, conditioned or delayed) (the "Dishes")
and   antennae   not  to  exceed   approximately   one  meter  in  height   (the
"Antennae")(the  foregoing  height and size  limitations  shall be  exclusive of
dimensions of any customary  pedestals,  platforms,  supports or other  mounting
devices associated with such equipment), and (3) screening, equipment, conduits,
cables and  materials  to be located on the Roof Space or in other  parts of the
Building  serving  the items  listed in clauses (1) and (2)  (collectively,  the
"Related Equipment") in accordance with the terms of this Section.  Tenant shall
have the  right to  locate  on the Roof  additional  equipment  associated  with
Tenant's  use of the  Premises  for the  Permitted  Uses,  provided  that Tenant
obtains  Landlord's  prior  consent  (which  consent  shall not be  unreasonably
withheld);  if  approved,  such  additional  equipment  shall be  subject to the
provisions  of  this  Paragraph  and  deemed  Related  Equipment  hereunder.  In
designating  the actual location of the Chillers,  Dishes,  Antennae and Related
Equipment,  Landlord shall use reasonable  efforts to accommodate  line of site,
avoidance of interference  and other technical  requirements to be satisfied for
the full functionality of such Chillers, Dishes, Antennae and Related Equipment.
In the event that the Roof Space is unsuitable for any such Dishes, Antennae and
Related  Equipment or cannot perform  according to Tenant's  requirements on the
Roof Space, Landlord shall reasonably consent to the use by Tenant of roof space
on  another  building  within  the  Building  Complex,  provided  that  space is
available  on such roof and the use,  location  and  equipment  is  approved  in
accordance with  Applicable  Laws and is otherwise  permitted in accordance with
the Declaration and agreements Landlord may have entered into with third parties
as of such time,  and  Tenant  agrees to be bound by the  requirements  to which
third party  tenants  are  required  to be bound  under  subsection  D, below in
respect  of their  use of the Roof  Space.  All costs and  expenses  related  to
installation  (including  costs of acquiring  any required  permits  therefor or
approvals  under the  Declaration),  maintenance,  operation  and removal of the
Chillers,  Dishes,  Antennae and Related  Equipment shall be borne by Tenant but
Tenant shall not pay any additional fee or Rent for use of the Chillers,  Dishes
Antennae and the Related Equipment under this Lease.

     A.  Tenant  will not use the Roof for any  purpose  other than  installing,
maintaining and operating the Chillers,  Dishes,  Antennae and Related Equipment
for  Tenant's  business  operations,  but shall not have any right to license or
otherwise  provide use of the Chillers,  Dishes,  Antennae and Related Equipment
other than in connection with Collocation Services.  Tenant's Agents agree to be
accompanied at all times by Landlord's designated  representative when access to
the Roof Space or Related Equipment areas is necessary for installation,  repair
and  maintenance;   Landlord  will  make  such  representative   available  upon
reasonable prior notice.  Tenant will make every  reasonable  effort to minimize
the number of service  calls made to the Roof Space or Related  Equipment  areas
and will enter such only for required  maintenance  or in case of an  emergency.
Tenant must secure and maintain at all times all required  approvals and permits
of the  Federal  Communications  Commission  and all other  governmental  bodies
having jurisdiction over its business, including its communications,  operations
and  facilities.  Landlord may require Tenant to cease  operation of or relocate
(at  Tenant's  cost and  expense)  the  Chillers,  Dishes,  Antennae and Related
Equipment  upon notice to Tenant if  Landlord  reasonably  determines  that such
installation  or use materially  interferes  with the operation of machinery and
apparatus of the  Building,  such as the  elevators,  and Tenant fails to remedy
such condition as soon as reasonably  practicable  and not later than 3 business
days. In no event shall Landlord be responsible for any interruption of services
or use of the  Building  caused by the  Chillers,  Dishes,  Antennae and Related
Equipment.  If the machinery or apparatus of the Building is equipment  that was
installed following  completion of the Base Building Work, the costs of any such
relocation shall be


                                       3
<PAGE>

borne by Landlord and the relocation is scheduled and performed in a manner that
minimizes any disruption to Tenant and its use of the Chillers, Dishes, Antennae
and Related  Equipment.  Landlord may suspend or terminate Tenant's right to use
the Roof under this  Section as required  upon  notice to Tenant,  to the extent
that it is found by a public  authority  having  jurisdiction  over the Building
that the  installation  and use of the  Chillers,  Dishes,  Antennae and Related
Equipment  constitute a nuisance or hazard to the public or to the  occupants of
the Building or if this Lease expires or is  terminated  in accordance  with its
terms. If Tenant fails to suspend or terminate  operations as so required at the
request of Landlord, Landlord will be entitled to injunctive relief and the cost
of obtaining such relief will be paid by the prevailing party.

     B. Upon  expiration or earlier  termination,  Tenant will, at its sole cost
and expense,  remove the Chillers,  Dishes,  Antennae and Related  Equipment and
repair any damage  caused to the Roof  Space and  restore  the Roof Space to the
condition   existing  prior  to  such  installation  to  the  extent  reasonably
practicable. Tenant will keep and maintain the Chiller, Dishes, Antennae and the
Related Equipment in good condition and repair, at its sole expense, in a manner
that does not conflict or  interfere  with the use of other  Building  equipment
installed  in the  Building  or on the Roof as of the  Delivery  Date.  Further,
Tenant  will  not  damage  or  permit  damage  to the  Roof or the  Building  in
conjunction with the Chillers, Dishes, Antennae and Related Equipment.

     C. All transmitters  must be equipped with any transmitter  isolator device
as may be required by law or as industry standard for such equipment to minimize
spurious  radiation.  Tenant  shall  indemnify  Landlord for all claims of third
parties with respect to  interference  from  operation of the Chillers,  Dishes,
Antennae and Related  Equipment.  Landlord makes no warranty that the Roof Space
is suitable for the Chillers,  Dishes, Antennae and Related Equipment or that it
will perform according to Tenant's requirements.

     D. Landlord and its agents, employees, contractors or anyone else permitted
by Landlord to be on the Roof may from time to time repair,  replace,  maintain,
or install  additional  improvements or fixtures on the Roof,  provided that the
same do not cause interference with the Chillers or to Tenant's Dishes, Antennae
and Related Equipment, and provided further,  however, that anyone other than an
employee of Landlord or the Building manager shall be required to be accompanied
by a representative  of Landlord or the Building manager at all times.  Landlord
shall not  license  the use of roof space to any third  parties  except to other
tenants in the  Worldgate  Complex  and only to such  tenants if the roof of the
building in which they are located is unsuitable  for operation of the equipment
proposed  to  be  used.  Tenant  will  cooperate  in  any  repair,  replacement,
maintenance  and  installation  as reasonably  required by Landlord from time to
time  consistent  with the  foregoing.  Landlord's  right to permit  such  other
licensees to install  other  rooftop  equipment,  shall be subject to Landlord's
undertaking  to use  reasonable  efforts to coordinate  such  installation  with
Tenant and to subject all such permissions,  licenses, easements and the like to
the condition that such other equipment shall not interfere with the Chillers or
Tenant's  Dishes,  Antennae  and  Related  Equipment  and  operations.   If  any
interference is caused by Landlord or any such other tenant, including,  without
limitation,  as a result of any  subsequent  change or addition of  equipment or
improvements by Landlord,  Landlord agrees to use reasonable  efforts to correct
and  eliminate  such  interference  at  Landlord's  cost in a prompt  and timely
manner,  not to exceed a period of 3 business  days after notice  thereof.  Such
efforts  may  include  modification  of the  third  party  tenant  equipment  or
relocation to another area mutually approved by Landlord and Tenant.

     E.  Tenant  will,  at  Tenant's  sole  cost and  expense,  comply  with all
Applicable  Laws,  or the  requirements  of  Landlord's  insurance  underwriters
relating to the installation, maintenance, height, location, use, operation, and
removal of said Dishes and Related Equipment and indemnify  Landlord against any
loss, cost, or expense incurred  resulting from the  installation,  maintenance,
operation,  or removal of said Dishes and Related  Equipment.  Landlord makes no
representation  that Applicable Laws permit the installation or operation of the
Dishes or Related Equipment.

     F. The insurance  required to be carried by Tenant under Section 16.2 shall
provide coverage with respect to the ownership,  operation and use of the Dishes
and the Related  Equipment.  Landlord has no  responsibility  or  liability  for
damage to the Dishes or the Related Equipment.

     4. Landlord is the owner of an adjacent  parcel of land known  generally as
Worldgate  Parcel 12 on which  Landlord is  constructing  an  additional  office
building  ("Plaza  III").  Landlord  agrees to offer to lease space to Tenant in
Plaza III in accordance with the following provisions:

     A.  Prior to  initial  leasing  of the 7th and 8th  floors  in  Plaza  III,
Landlord shall give notice to Tenant (the "Offer  Notice") of Landlord's  desire
to lease such floors to Tenant (the "RFO  Space"),  provided  that,  if Landlord
desires  at such  time to offer a  portion  or all of the 7th and 8th  floors to
another  proposed  tenant in conjunction  with leasing other space in Plaza III,
Landlord  shall have a right to identify  all of the space being  proposed to be
leased as well (the space  being  proposed  outside of the RFO Space 7th and 8th
floors is referred to collectively as the "Additional Space"); however, Landlord
shall not include  Additional  Space unless the square footage  available on the
7th and 8th floors is not adequate to accommodate the proposed  leasing.  Tenant
has 10 calendar days after  receipt of  Landlord's  Offer Notice within which to
notify  Landlord  if it  elects  to  exercise  its  Right of Offer as to (i) the
entirety  of the RFO Space  floors  included  in such  proposal  (if there is no
Additional  Space  identified  in the Offer Notice) or (ii) the RFO Space floors
included in such proposal and the Additional Space (if there is Additional Space
identified in the Offer Notice).  If there is Additional  Space set forth in the
Offer Notice and Tenant elects to lease the Additional Space,  Tenant shall have
a right to also take the balance of the 7th and 8th floors then available  which
is not  included  in Offer  Notice.  For  example,  if Landlord  identifies  the
Additional  Space as both the 5th and 6th floors and the RFO Space as 1/2 of the
7th floor,  Tenant  shall have the right to elect to  exercise as to (1) the 5th
and 6th floors and all of the 7th,  or (2) the 5th and 6th floors and all of the
7th and all of the 8th floor (assuming the 8th floor is then available).  To the
extent that the  Additional  Space  includes  portions or all of the 5th and 6th
floors in Plaza III, Tenant's right under this Paragraph shall be subject to the
pre-existing rights of Onepoint  Communications  Corp. as tenant under its lease
for space in Plaza I. The space Tenant elects to lease,  in accordance  with the
foregoing  provisions,  as set forth in Tenant's  responsive  notice  ("Tenant's
Election Notice") shall be deemed the "Offer Space."

     B. If Tenant  does not  timely  notify  Landlord,  it will be  conclusively
presumed  that  Tenant has waived its Right of Offer as to the floors of the RFO
Space  included  in the  Offer  Notice,  Landlord  shall  be free to  lease  the
described  RFO Space to anyone  whom it desires  and Tenant will have no further
rights  to the  respective  floors of RFO Space  included  in the Offer  Notice,
provided,  however,  that if after Tenant  waives its right as to any such space
Landlord  desires to lease the space to a prospective  tenant on materially more
beneficial  terms than  provided in  Landlord's  Offer  Notice,  Landlord  shall
re-offer such space on such changed  terms to Tenant  before  leasing to a third
party.  If the Offer  Notice  did not  include  both  floors  of the RFO  Space,
Tenant's  rights as to the excluded floor shall continue in accordance  with the
terms of this  Paragraph  4. For  purposes of this  Addendum:  "more  beneficial
terms"  means an  effective  per square foot rental rate  (taking  into  account
amortization  of  allowances  and rent credits on a straight line basis over the
applicable  term)  which is less  than the rate set  forth in  Landlord's  Offer
Notice;  "materially  more  beneficial  terms"  means an  effective  rental rate
(taking into account  amortization  of allowances and rent credits on a straight
line  basis  over the  applicable  term)  which is 90% or less than the rate set
forth in Landlord's Offer Notice.

     C. The Offer  Notice  shall  include  the lease  term,  the per square foot
rental  rate,  per square  foot  finish  allowance,  terms and  conditions  that
Landlord desires offer to lease the respective space to third parties (including
finish allowance and lease provisions), but in no event shall the rental rate be
less  than the per  square  foot  rental  rate that  Tenant  is  paying  for the
Premises. Except as set forth in Landlord's Offer Notice, the provisions of this
Lease shall be  applicable to such space and, at  Landlord's  option,  evidenced
either in a  separate  lease or, if  mutually  agreed by  Landlord  and  Tenant,
amendment to this Lease;  however,  the provisions of this Addendum shall not be
applicable  to such space and  provisions  regarding  services,  calculation  of
Operating  Expenses  (except  exclusions  of Operating  Expenses  not  otherwise
logically  inapplicable)  and  other  provisions  applicable  to  such  separate
building shall be subject to separate  determination and calculation  consistent
with other leases of space in Plaza III.  Except any finish  allowance  and work
letter  provisions  referred to in the Offer Notice,  all costs of preparing the
space for Tenant's occupancy, including costs of compliance with Applicable Laws
(except  for  compliance  that is the  obligation  of  Landlord  under such work
letter), will be paid by Tenant.


                                       5
<PAGE>

     D. Tenant's  rights under this Paragraph 2 are  conditioned  on: (i) Tenant
not being in default under the Lease at the time it delivers  Tenant's  Election
Notice or on the date that Tenant's  occupancy of the Offered Space is scheduled
to commence;  (ii) Tenant not having  vacated or subleased  more than 25% of the
Premises  or  assigned  its  interest in the Lease  (except as  permitted  under
Section 14.7 of the Lease) at the time it exercises the Right of Offer or on the
date that Tenant's occupancy of the Offered Space is scheduled to commence;  and
(iii) there being at least 2 years  remaining in the Term.  Notwithstanding  the
foregoing,  if there are less than two years  remaining in the Term but Tenant's
rights under this paragraph would otherwise be available to Tenant and an option
to extend the Term is  available  to Tenant  hereunder,  Tenant may exercise its
rights under this Paragraph  provided that Tenant  simultaneously  exercises its
option to extend the term of the Lease. Tenant's rights under this paragraph are
personal to Tenant and may not be assigned  (except as permitted  under  Section
14.7 of the  Lease) and upon an  assignment  of the Lease  (except as  permitted
under Section 14.7), this Paragraph is null and void.

     5.  Tenant,  at  Tenant's  sole cost and  expense,  shall have the right to
install an emergency generator  ("Generator"),  generator fuel tank ("Generat or
Fuel Tank") and  uninterrupted  battery  power source (the "UPS"),  as generally
described  on  EXHIBIT  5 to the  Work  Letter,  ("collectively  the  Generator,
Generator Fuel Tank and UPS are referred to as the "Backup  System") and related
equipment connecting such Backup System to the Premises, including the equipment
referred  to under the  heading  "Riser  Backup  Power" on EXHIBIT 5 to the Work
Letter (the "Backup Related Equipment"). The Generator,  Generator Fuel Tank and
the UPS shall be located in the areas of the Building  Complex labeled "(3)" for
the Generator and Generator Fuel Tank and "(2)" for the UPS on the parking level
one plan  attached as part of EXHIBIT I, with the exact  location and space used
being  designated  by Landlord,  as  reasonably  approved by Tenant.  The Backup
System  and  Backup  Related   Equipment  shall  be  subject  to  the  following
provisions:

     A. The specifications  and types of Generator,  Generator Fuel Tank and UPS
and Backup Related Equipment,  and any alterations thereto,  shall be subject to
the prior  approval  of  Landlord,  which  approval  shall  not be  unreasonably
withheld.

     B. Upon  expiration or earlier  termination,  Tenant will, at its sole cost
and  expense,  remove  and retain  the  Backup  System  and the  Backup  Related
Equipment  and return  the  Building  to the  condition  existing  prior to such
installation.  Tenant will keep and  maintain  the Backup  System and the Backup
Related Equipment in good condition and repair, at its sole expense, in a manner
that does not conflict or interfere with the use of other  facilities  installed
in the  Building.  Further,  Tenant  will not  damage  or  permit  damage to the
Building in conjunction with the Backup System and the Backup Related Equipment.
The  Backup  System and Backup  Related  Equipment  will be of types that do not
cause  interference  with other  equipment  or  operations  in the  Building  or
surrounding  areas to the extent such  interference is unacceptable to Landlord,
in Landlord's reasonable determination.

     C.  Tenant  will,  at  Tenant's  sole  cost and  expense,  comply  with all
applicable laws, rules, regulations,  statutes, ordinances or other requirements
of any kind or  nature  of any  municipal,  state and  federal  governmental  or
quasi-governmental   authority  or  the  requirements  of  Landlord's  insurance
underwriters relating to the installation,  maintenance,  height, location, use,
operation,  and removal of the Backup  System and Backup  Related  Equipment and
indemnify  Landlord against any loss,  cost, or expense incurred  resulting from
the installation,  maintenance,  operation,  or removal of the Backup System and
Backup Related Equipment. Landlord makes no representation that applicable laws,
ordinances or  regulations  permit the  installation  or operation of the Backup
System or Backup  Related  Equipment.  The  insurance  required to be carried by
Tenant under Section 16.2 shall provide  coverage with respect to the ownership,
operation  and use of the  Backup  System  and  the  Backup  Related  Equipment.
Landlord has no  responsibility  or liability for damage to the Backup System or
the Backup Related Equipment.

     6. This Lease is conditioned, at Landlord's option, on Landlord obtaining a
guaranty of the performance of Tenant's obligations and covenants hereunder from
Guarantor,  Bridge Information Systems,  Inc., a Missouri  corporation,  in form
acceptable to Landlord (the  "Guaranty"),  which is subject to  substitution  in
accordance with Section 9.

EXHIBIT C TO LEASE

                               OPERATING EXPENSES

     6.1 Definitions.  The additional terms below have the following meanings in
this Lease:

     (1)  "Base  Operating  Expenses"  means an  amount  equal to the  Operating
Expenses for the calendar  year  identified  as the Base Year in Section 1.5, as
determined  by Landlord in accordance  with this Exhibit C. Tenant  acknowledges
Landlord has not made any  representations or warranties that the Base Operating
Expenses will equal any specified  amounts (any  estimates  provided by Landlord
are non-binding estimates only).

     (2)  "Landlord's  Accountants"  means that  individual  or firm employed by
Landlord  from  time to time to keep the  books  and  records  for the  Building
Complex, and/or to prepare the federal and state income tax returns for Landlord
with respect to the Building Complex, which books and records shall be certified
to by a representative of Landlord.  All determinations  made hereunder shall be
made by Landlord's Accountants unless otherwise stated.

     (3) "Rentable Area" means 80,582 rentable square feet of space. If there is
a significant  change in the aggregate Rentable Area as a result of an addition,
partial  destruction,  modification to building  design,  or similar cause which
causes a reduction or increase in the Rentable Area on a permanent  basis or, if
Landlord  remeasures  the  Building  and  a  change  in  Rentable  Area  occurs,
Landlord's  Accountants  shall make such  adjustments in the computations as are
necessary to provide for such change.

     (4)  "Tenant's  Pro Rata Share" means the  percentage  set forth in Section
1.5. If Tenant,  at any time  during the Term,  leases  additional  space in the
Building or if the Rentable  Area is adjusted,  Tenant's Pro Rata Share shall be
recomputed by dividing the total rentable square footage of space then leased by
Tenant  (including any additional  space) by the Rentable Area and the resulting
figure shall become Tenant's Pro Rata Share.

     (5)  "Operating  Expense  Year" means each  calendar  year during the Term,
except that the first Operating Expense Year begins on the Commencement Date and
ends on December 31 of such year and the last  Operating  Expense Year begins on
January 1 of the calendar year in which this Lease expires or is terminated  and
ends on the date of such expiration or termination. If an Operating Expense Year
is less than  twelve  (12)  months,  Operating  Expenses  for such year shall be
prorated.

     (6) "Operating Expenses" means all operating expenses of any kind or nature
which  are  in  Landlord's  reasonable  judgment  necessary,   appropriate,   or
customarily  incurred in connection  with the operation and  maintenance  of the
Building Complex. Operating Expenses include:

     (a) All real property taxes and assessments levied against the Building and
a proportionate share of amounts levied against the rest of the Building Complex
by any  governmental  or  quasi-governmental  authority or under any  covenants,
declarations,   easements  or  restrictions,   including   taxes,   assessments,
surcharges,  or service or other fees of a nature not  presently in effect which
are hereafter levied on the Building  Complex as a result of the use,  ownership
or operation of the Building Complex or for any other reason, whether in lieu of
or in addition to, any current real estate taxes and assessments.  However,  any
taxes which are levied on the rent of the Building Complex will be determined as
if the Building Complex were Landlord's only real property. In no event do taxes
and assessments  include any federal or state income taxes levied or assessed on
Landlord.  Expenses for tax consultants to contest taxes or assessments are also
included as Operating  Expenses (all of the foregoing are collectively  referred
to herein as "Taxes").  Taxes also include special  assessments,  license taxes,
business license fees, business license taxes,  commercial rental taxes, levies,
charges,  penalties or taxes,  imposed by any  authority  against the  Premises,
Building  Complex  or any  legal or  equitable  interest  of  Landlord.  Special
assessments are deemed payable in such number of installments  permitted by law,
whether or not actually so paid,  and include any applicable  interest,  but not
penalties or penalty interest on such installments. Taxes


                                       1
<PAGE>

(other than special  assessments)  are computed on an accrual basis based on the
year in  which  they are  levied,  even  though  not paid  until  the  following
Operating  Expense Year.  Notwithstanding  the foregoing or anything else to the
contrary, The terms "taxes", "assessments",  "special assessments," "Real Estate
Taxes"  "real   property   taxes"  or  "Taxes"   shall  exclude  (and  under  no
circumstances shall Real Estate Taxes or Taxes include) profit taxes,  franchise
taxes,  inheritance  taxes, gift taxes,  transfer taxes,  excise taxes,  capital
levies or similar taxes on Landlord's  business or any assessments to the extent
no substantial  benefit  accrues to Tenant.  In addition,  if the Building,  the
parking  facilities  or the  Property  are  subject  to any  provision  for  tax
abatement  during  the Base  Year as a result  of the  incomplete  status of the
Building Complex, the Base Operating Expenses for determining  increases in Real
Estate  Taxes shall be adjusted to reflect the  estimated  taxes that would have
been  applicable  for  a  fully  completed  Building  Complex.   If  substantial
additional  improvements  are added to the Plaza I Building or if there occurs a
rehabilitation  of or improvement  to the Plaza I Building,  Tenant shall not be
responsible  for increases in Real Estate Taxes  attributable to such additional
improvements  or  rehabilitation.  In the event any tax contest is  pending,  in
progress  or  contemplated  in respect of the Real Estate  Taxes,  the base Real
Estate  Taxes  for  determining  Tenant's  share  shall  not  be  reduced  as  a
consequence  of such contest until a final  determination.  In the event any tax
contest  subsequent  to the year on which base Real Estate Taxes are  determined
shall  result in a  reduction  of Real  Estate  Taxes,  Operating  Expenses  and
Tenant's Pro Rata Share of  Operating  Expenses  for the  applicable  Lease Year
shall be readjusted  upon a final  determination.  Landlord shall be entitled to
deduct  from the amount of the  readjustment  the actual out of pocket bona fide
expenses  incurred  by  Landlord  in  securing  such  reduction  so long as such
expenses are  appropriately  allocated to the  respective  years as to which the
reduction applies;

     (b) Costs of supplies,  including costs of relamping and replacing ballasts
in all Building standard tenant lighting;

     (c) Costs of energy for the Building  Complex,  including costs of propane,
butane, natural gas, steam, electricity, solar energy and fuel oils, coal or any
other energy sources;

     (d) Costs of water and sanitary and storm drainage services;

     (e) Costs of janitorial and security services;

     (f) Costs of general maintenance, repairs, and replacements including costs
under  HVAC  and  other  mechanical  maintenance  contracts;   and  repairs  and
replacements  of equipment used in  maintenance  and repair work;

     (g) Costs of maintenance, repair and replacement of landscaping;

     (h)  Insurance  premiums for the Building  Complex,  including  all-risk or
multi-peril  coverage,  together with loss of rent endorsement;  the part of any
claim  paid under the  deductible  portion of any  insurance  policy  carried by
Landlord;  public  liability  insurance;  and any  other  insurance  carried  by
Landlord on any component parts of the Building Complex;

     (i) All  labor  costs,  including  wages,  costs of  worker's  compensation
insurance, payroll taxes, fringe benefits, including pension, profit-sharing and
health, and legal fees and other costs incurred in resolving any labor dispute;

     (j) Professional  building  management fees, costs and expenses,  including
costs of office space and storage space required by management  for  performance
of its services;

     (k) Legal,  accounting,  inspection,  and other  consulting fees (including
fees for consultants  for services  designed to produce a reduction in Operating
Expenses  or  improve  the  operation,  maintenance  or state of  repair  of the
Building Complex);


                                       2
<PAGE>

     (l) Costs of capital  improvements and structural  repairs and replacements
to the Building Complex to conform to changes subsequent to the date of issuance
of the  shell  and  core  certificate  of  occupancy  for  the  Building  in any
Applicable Laws (herein "Required Capital  Improvements");  and the costs of any
capital improvements and structural repairs and replacements  designed primarily
to reduce Operating Expenses (herein "Cost Savings Improvements").  Expenditures
for  Required  Capital  Improvements  and  Cost  Savings  Improvements  will  be
amortized  at a market  rate of interest  over the useful  life of such  capital
improvement (as determined by Landlord's  Accountants);  however,  the amortized
amount  of any  Cost  Savings  Improvement  in any  year  will be  equal  to the
estimated resulting reduction in Operating Expenses; and

     (m)  Costs  incurred  for  Landlord's  Accountants  including  costs of any
experts and consultants engaged to assist in making the computations;

"Operating Expenses" do not include:

     (i)  Costs of work,  including  painting  and  decorating,  which  Landlord
performs  for any tenant  other than work of a kind and scope which  Landlord is
obligated  to furnish to all tenants  whose leases  contain a rental  adjustment
provision similar to this one;

     (ii)  Costs  of  repairs,   renovation   or  rebuilding   necessitated   by
condemnation or the exercise of eminent domain or other work occasioned by fire,
windstorm  or  other  insured  casualty  to the  extent  of  insurance  proceeds
received;

     (iii) Any and all of Landlord's costs to lease space in the Building to all
prior,  existing,  and  prospective  tenants,  including,   without  limitation:
consulting  and  marketing  fees,  leasing  commissions,  advertising  expenses,
brokerage   commissions,   legal  fees,   vacancy  costs,  rent  or  other  rent
concessions,   and/or  refurbishment  or  improvement  expenses;  and  costs  of
preparing,  improving or altering any space in preparation  for occupancy of any
new or renewal tenant; rent for management or leasing offices;

     (iv) Costs for any structural maintenance constituting Capital Improvements
or  replacement  or redesign of the  structure  (except  for  Permitted  Capital
Improvements),  including, without limitation, any financing related fees, costs
and expenses,  depreciation  or amortization of costs required to be capitalized
in  accordance  with  generally   accepted   accounting   principles   ("Capital
Improvements")  (other than Permitted  Capital  Improvements),  and professional
fees and  disbursements  incurred  in  connection  therewith;  rentals and other
expenses incurred in leasing systems,  elevators,  or other equipment ordinarily
considered to be of a capital nature,  and costs incurred to achieve  compliance
with any governmental laws, ordinances, rules, regulations or orders (other than
Permitted Capital Improvements);

     (v) Any and all of  Landlord's  payment of  principal or interest due under
any mortgage or deed of trust, payments pursuant to ground leases, declarations,
easements,  license  agreements,  and payments  pursuant to any other agreements
that do not constitute  operating expenses under generally  accepted  accounting
principles,  or for any costs or  expenses  relating to  Landlord's  obligations
under any work letter to construct Tenant improvements;

     (vi) Any and all of  Landlord's  costs to  compel  full  performance  under
leases  with all  prior,  existing  and  prospective  tenants  at the  Building,
including,  without  limitation,  all legal fees, costs, and expenses to collect
rent arrears and recover possession;

     (vii) Compensation  (exclusive of the professional building management fee)
paid to officers of Landlord or officers of the management  agent or anyone else
above the level of Building  manager,  and salaries of Landlord's  employees who
are not engaged in the  day-to-day  management  and  maintenance of the Premises
including,  without limitation,  any compensation paid to clerks,  attendants or
other  persons in  commercial  concessions  operated for profit by Landlord,  or
wages,  salaries or other  compensation  or benefits of other offsite  employees
applicable to the time


                                       3
<PAGE>

spend working at other buildings, other than the Building manager (provided that
with respect to each employee that services the Building and other buildings,  a
pro  rata  share  of such  employee's  salary  shall be  included  in  Operating
Expenses, as applicable);

     (viii) Any costs  incurred to Landlord or an  affiliate of Landlord for the
provision of any goods or  services,  in excess of the cost then  prevailing  in
similar transactions between unrelated parties.

     (ix) Depreciation on the Building Complex, except as specifically set forth
above;

     (x)  Expenses  for  the   correction  of  defects  in  Landlord's   initial
construction  of  the  Building,  Project,  or any  part  thereof,  except  that
conditions (not occasioned by construction defects) resulting from ordinary wear
and tear will not be deemed defects for the purpose of this  category;  the cost
of repair or replacement of any item covered by warranty;

     (xi) The cost of tools, equipment and material used in, and all other costs
associated  with, the initial  construction  of the Building,  the Project,  and
related  facilities;  the cost of any "tap  fees" or one time  lump sum sewer or
water connection fees for the Property;

     (xii) Any  documentary  and transfer  taxes imposed in connection  with the

wastes, or asbestos-containing  materials in or about or below the Building, the
Land, or the Project, including without limitation,  hazardous substances in the
groundwater or soil (other than ordinary  maintenance costs,  including changing
filters, etc.), unless the materials,  substances, wastes or asbestos-containing
materials  were in or on the Property due to Tenant's  negligence or intentional
acts;

     (xiv)  Property  management  fees in excess of Five  Percent  (5%) of gross
rentals generated by the Property; and

     (xv)  Interest  on  borrowed   money  or  debt   amortization,   except  as
specifically set forth above.

To the  extent  that  employees,  utilities  or  other  services  or  costs  are
attributable  to the  Building  and  other  buildings  on a common  basis or are
provided for Common Areas, such Operating Expenses shall be reasonably  prorated
by Landlord to reflect costs to be allocated  hereunder to the Building.  If any
lease entered into by Landlord with any tenant in the Building is on a so-called
"net" basis,  or provides for a separate basis of computation  for any Operating
Expenses with respect to its leased premises,  Landlord's Accountants may modify
the  computation  of Base  Operating  Expenses,  Rentable  Area,  and  Operating
Expenses  for a  particular  Operating  Expense  Year to eliminate or modify any
expenses which are paid for in whole or in part by such tenant.  If the Rentable
Area is not  fully  occupied  during  any  particular  Operating  Expense  Year,
Landlord's Accountants may adjust those Operating Expenses which are affected by
occupancy for the particular  Operating  Expense Year to reflect 100% occupancy.
Furthermore,   in  making  any  computations   contemplated  hereby,  Landlord's
Accountants  may  make  such  other  modifications  to the  computations  as are
required in their judgment to achieve the intention of the parties hereto.

     6.2 Additional  Payment.  If any increase occurs in Operating  Expenses for
any  Operating  Expense  Year  during  the Term in excess of the Base  Operating
Expenses,  Tenant  shall pay  Landlord  Tenant's Pro Rata Share of the amount of
such increase (less Estimated  Payments,  if any,  previously made by Tenant for
such year).

     6.3 Estimated  Payments.  During each Operating Expense Year beginning with
the first month of the second  Operating  Expense Year and continuing each month
thereafter  throughout the Term, Tenant shall pay Landlord,  at the same time as
Base Rent is paid,  an amount equal to 1/12 of  Landlord's  estimate of Tenant's
Pro  Rata  Share  of any  projected  increases  in  Operating  Expenses  for the
particular   Operating  Expense  Year  in  excess  of  Base  Operating  Expenses
("Estimated Payment").


                                       4
<PAGE>

     6.4 Annual Adjustments.

     (1) Following the end of each Operating  Expense Year,  including the first
Operating  Expense  Year,  Landlord  shall submit to Tenant a statement  setting
forth the exact  amount of Tenant's Pro Rata Share of the  increase,  if any, of
the Operating  Expenses for the Operating  Expense Year just  completed over the
Base Operating  Expenses.  Beginning with the statement for the second Operating
Expense Year,  each statement shall set forth the  difference,  if any,  between
Tenant's  actual Pro Rata Share of the  increase in  Operating  Expenses for the
Operating  Expense  Year  just  completed  and the  estimated  amount  for  such
Operating  Expense  Year.  Each  statement  shall  also set forth the  projected
increase,  if any, in Operating Expenses for the new Operating Expense Year over
Base Operating  Expenses and the corresponding  increase or decrease in Tenant's
monthly Rent for such new Operating Expense Year above or below the Rent paid by
Tenant for the  immediately  preceding  Operating  Expense Year.  All statements
related to  Operating  Expenses  shall be broken down on a  reasonably  itemized
basis. All books and records pertaining to Operating Expenses and all statements
relating  thereto  shall  conform to generally  accepted  accounting  principles
consistently applied.

     (2) To the extent that Tenant's Pro Rata Share of the increase in Operating
Expenses for the period  covered by a statement is different  from the Estimated
Payment  during the  Operating  Expense  Year just  completed,  Tenant shall pay
Landlord  the  difference  within  30 days  following  receipt  by Tenant of the
statement  or receive a credit  against  the next due Rent,  as the case may be.
Until  Tenant  receives a  statement,  Tenant's  Estimated  Payment  for the new
Operating Expense Year shall continue to be paid at the prior Estimated Payment,
but Tenant shall  commence  payment of Rent based on the new  Estimated  Payment
beginning  on the  first day of the month  following  the month in which  Tenant
receives the statement.  Tenant shall also pay Landlord or deduct from the Rent,
as the case may be, on the date required for the first payment, as adjusted, the
difference,  if any, between the Estimated Payment for the new Operating Expense
Year set forth in the statement and the Estimated  Payment  actually paid during
the new Operating  Expense Year. If, during any Operating Expense Year, there is
a change  in the  information  on which  Tenant  is then  making  its  Estimated
Payments so that the prior estimate is no longer  accurate,  Landlord may revise
the estimate and there shall be such adjustments made in the monthly Rent on the
first day of the month  following  notice  to  Tenant as shall be  necessary  by
either increasing or decreasing,  as the case may be, the amount of monthly Rent
then being paid by Tenant for the balance of the Operating Expense Year.

     6.5  Miscellaneous.  In no event will any decrease in Rent  pursuant to any
provision  hereof  result in a reduction  of Rent below the Base Rent.  Delay by
Landlord in submitting  any  statement  for any Operating  Expense Year does not
affect the  provisions  of this  Section or  constitute  a waiver of  Landlord's
rights for such  Operating  Expense  Year or any  subsequent  Operating  Expense
Years.

     6.6 Dispute.  If Tenant  disputes an adjustment  submitted by Landlord or a
proposed  increase or  decrease  in the  Estimated  Payment,  Tenant  shall give
Landlord  notice of such dispute within 180 days after  Tenant's  receipt of the
adjustment.  If Tenant does not give Landlord  timely notice,  Tenant waives its
right to dispute the particular adjustment. If Tenant timely objects, Tenant may
engage its own certified public accountants  ("Tenant's  Accountants") to verify
the  accuracy  of  the  statement  complained  of or the  reasonableness  of the
estimated increase or decrease.  The person conducting the examination on behalf
of Tenant shall enter into a confidentiality agreement satisfactory to Landlord.
If  Tenant's  Accountants  determine  that an error  has been  made,  Landlord's
Accountants  and Tenant's  Accountants  shall endeavor to agree upon the matter,
failing which such matter shall be submitted to an independent  certified public
accountant  selected by  Landlord,  with  Tenant's  reasonable  approval,  for a
determination which will be conclusive and binding upon Landlord and Tenant. All
costs  incurred by Tenant for Tenant's  Accountants  shall be paid for by Tenant
unless  Tenant's  Accountants  disclose  an error,  acknowledged  by  Landlord's
Accountants   (or  found  to  have  occurred   through  the  above   independent
determination),  of more  than 5% in the  computation  of the  total  amount  of
Operating  Expenses,  in which event  Landlord  shall pay the  reasonable  costs
incurred by Tenant to obtain such audit. Notwith-


                                       5
<PAGE>

standing the pendency of any dispute,  Tenant shall continue to pay Landlord the
amount  of  the  Estimated  Payment  or  adjustment   determined  by  Landlord's
Accountants  until the adjustment has been determined to be incorrect.  If it is
determined  that  any  portion  of the  Operating  Expenses  were  not  properly
chargeable  to  Tenant,  then  Landlord  shall  promptly  credit or  refund  the
appropriate sum to Tenant.

any  person  leaving  the  Building  with a package  or other  object to exhibit
authorization  from the Tenant of the premises  from which the package or object
is removed,  but the establishment and enforcement of such requirement shall not
impose any  responsibility  on the  Landlord to protect  any Tenant  against the
removal of property from its premises. The Landlord shall in no way be liable to
any Tenant for damages or loss arising from the admission, exclusion or ejection
of any person to or from Tenant's  Premises or the Building under the provisions

shall be  construed  as a waiver of such Rules and  Regulations  in favor of any
other tenant or tenants, nor prevent Landlord from thereafter enforcing any such
Rules and Regulations against any or all of the tenants of the Building.

construed  to in any way  modify  or  amend,  in whole or in  part,  the  terms,

     SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT AGREEMENT
     THIS  SUBORDINATION,   NON-DISTURBANCE   AND  ATTORNMENT   AGREEMENT  (this
"Agreement")  is made as of the  24th  day of  January,  2000  among  U.S.  BANK
NATIONAL ASSOCIATION, a national banking association ("Lender"), WGP ASSOCIATES,
LLC,  a   Virginia   limited   liability   company   ("Landlord"),   and  Savvis
Communications Corporation, a Missouri corporation ("Tenant").

                                    RECITALS
     A. Lender has made a loan to Landlord (the "Loan"),  upon certain terms and
conditions.

     B. The Loan is secured by, among other  things,  a Deed of Trust,  Security
Agreement,  Financing Statement and Assignment of Leases and Rents (the "Deed of
Trust")  executed by Landlord for the benefit of Lender and recorded in the real
estate records of Fairfax County,  Virginia on April 16, 1999 in Deed Book 10865
at Page 932. The Deed of Trust  created a first lien upon that certain  tract of
real  property  described  on  Exhibit  A  attached  hereto,  together  with the
improvements constructed or to be constructed thereon (the "Property"). The Loan
is  also  secured  by  other  security  agreements,   financing  statements  and
assignments  (the  Deed of Trust and all such  other  security  instruments  are
hereinafter collectively referred to as the "Collateral Documents").

     C. Tenant is the lessee of part of the Property (the  "Demised  Premises"),
under and by virtue of a lease (the "Lease")  between  Landlord and Tenant dated
January 24, 2000.

     D. It is a  condition  to the Lease that  Lender  confirm  certain  matters
relating  to the Loan and  Lender  is  willing  to do so  provided  that  Tenant
subordinates  the Lease and all of Tenant's rights  thereunder to the Collateral
Documents and the liens and security interests created thereby.

                                    AGREEMENT

     NOW,  THEREFORE,  for good and  valuable  consideration,  the  receipt  and
sufficiency of which are hereby acknowledged, Lender, Landlord and Tenant hereby
agree as follows:

     1. SUBORDINATION.  The Lease and all of Tenant's rights thereunder are, and
shall at all times continue to be,  subordinate to the Collateral  Documents and
the liens and security interests created thereby,  regardless of how often or in
what manner the Loan,  together with the liens securing the same, and any of the
Collateral Documents, may be increased, renewed, extended or modified.

     2. NON-DISTURBANCE.  So long as Tenant is not in default in the performance
of any of the terms, covenants or conditions of the Lease on Tenant's part to be
performed,  after the  expiration  of any grace  periods set forth in the Lease,
Tenant's  possession  and  occupancy  of the Demised  Premises  and the Tenant's
rights and privileges under the Lease shall not be diminished or interfered with
by Lender in the exercise of any of Lender's rights under the Deed of Trust.

     3.  ATTORNMENT.  In the event of the foreclosure of the lien of the Deed of
Trust or if the  Demised  Premises  are  conveyed  to  Lender by deed in lieu of
foreclosure,  Tenant  shall  attorn  to Lender  or the  purchaser  upon any such
conveyance or foreclosure  sale and shall recognize  Lender or such purchaser as
the  lessor  under the Lease and  Lender or such  purchaser  shall have the same
rights  and  remedies  under the Lease as  Landlord.  Such  attornment  shall be
effective and self-operative  without the execution of any further instrument on
the part of any of the  parties  hereto.  From and  after  any such  attornment,
Lender  or such  purchaser  shall be bound to  Tenant  under  all of the  terms,
covenants and conditions of the Lease;  provided,  however,  that Lender or such
purchaser shall not be:


                                       1
<PAGE>

     (a)  liable  for any  action or  omission  of any prior  lessor  (including
Landlord)  except for the right of the Tenant to recoup its  damages for a prior
lessor's  default which have been reduced to a final  judgment  against the Rent
owed under the Lease;

     (b)  bound by any rent  which  Tenant  might  have  paid for more  than the
current month to any prior lessor (including Landlord);

     (c) liable for the return or  application of any security  deposits  unless
Landlord delivers such deposits to Lender or such purchaser;

     (d)  bound by any  amendment  or  modification  of the Lease  made  without
Lender's written consent, which consent shall not be unreasonably withheld; or

     (e) subject to any offsets or  deficiencies  which Tenant might be entitled
to assert against any prior lessor (including  Landlord) except for the right to
recoup its damages for a prior Lessor default which have been reduced to a final
judgment against the Rent owed under the Lease.

     4.  NO  DIMINUTION  OF  LANDLORD'S  RIGHTS.  Nothing  contained  herein  is
intended, nor shall it be construed, to abridge or adversely affect any right or
remedy of  Landlord  under the  Lease in the event of  default  by Tenant in the
performance  of any of the  terms,  covenants  or  conditions  of the  lease  on
Tenant's part to be performed.

     5. NOTICES.  If Tenant gives Landlord notice requesting  arbitration of any
alleged  Landlord  default,  it shall  simultaneously  serve a duplicate  of the
notice  on  Lender,  and  Lender  shall  have the right to  participate  in such
arbitration.  Any notice required or permitted to be given hereunder shall be in
writing and will be deemed given (a) upon personal delivery or upon transmission
by  telecopier  or  similar  facsimile  transrnission  device,  (b) on the first
business day after  receipted  delivery to a courier  service  which  guarantees
next-business-day  delivery,  or (c) on the third business day after mailing, by
registered or certified United States mail, postage prepaid,  in any case to the

SAVVIS COMMUNICATIONS CORPORATION

RE:   Lease dated as of the 24th of January,  2000 (the "Lease"), by and between
      WGP ASSOCIATES,  LLC, a Virginia limited liability  company,  as Landlord,
      and SAVVIS COMMUNICATIONS CORPORATION, a Missouri corporation, as Tenant

Re:  Tenant:   SAVVIS COMMUNICATIONS CORPORATION, a Missouri corporation,

Premises:      Approximately   80,582  rentable square feet of space on the 5th,
               6th, 7th and 8th floors (the "Premises")

Address:       12851 Worldgate Drive, Herndon, Virginia

Gentlemen:

     Concurrently herewith, you ("Tenant") and the undersigned ("Landlord") have
executed a Lease (the  "Lease")  covering  the Premises  (initially  capitalized
words not  defined  have the same  meaning  set forth in the  Lease).  This Work
Letter sets forth how certain base building  construction (as defined more fully
below,  "Base Building Work") and certain  interior  finish  construction of the
Premises to be leased by Tenant  pursuant  to the Lease (as  defined  more fully
below,  "Tenant's  Finish Work") are to be constructed,  who will be responsible
for the construction of the base building  improvements and tenant improvements,
who will pay for such  construction,  and the time schedule and  coordination of
activities for the completion of such construction.  All provisions of the Lease
shall apply to this  Agreement  except to the extent clearly  inconsistent  with
this Agreement or otherwise inapplicable. This Agreement is a part of the Lease.
In  consideration  of the execution of the Lease,  Landlord and Tenant  mutually
agree as follows:

1.  Base Building Work; Space Planning and Engineering

1.1 Landlord has provided to Tenant the architectural  and engineering  drawings
for the base building  improvements for the Building and the Building Complex to
be completed by Landlord  ("Base  Building  Drawings")(as  further  described on
EXHIBIT 4 to this Work Letter),  as prepared by Davis, Carter & Scott Architects
(such  architectural  firm or its replacement,  if replaced by Landlord prior to
completion of construction,  is referred to as the "Landlord's Architect").  The
work to be completed by Landlord in accordance  with the Base Building  Drawings
as modified is hereinafter  referred to as the "Base Building Work." Landlord is
responsible  for  having  completed  the  Base  Building  Work  in  a  good  and
workmanlike  manner in accordance with Applicable Laws and the  Declaration,  as
further provided in Section 2.4.

1.2 Tenant has  retained  Davis Carter  Scott as Tenant's  architect  ("Tenant's
Architect") and Burr Computer Environments, Inc. as Tenant's engineer on the 6th
floor and Tolk  Engineering  Inc.  or  Shapiro-O'Brien  Associates  as  Tenant's
overall engineer ( collectively,  "Tenant's  Engineers");  Landlord reserves the
right to elect to retain separate engineers ("Landlord's  Engineers") to provide
a separate review on behalf of Landlord of plans prepared by Tenant's  Architect
and Tenant's Engineers (which review shall be at Landlord's cost and expense and
not as a deduction  from the  Allowance  except  that cost of a review,  if any,
required in  connection  with any request of Tenant to modify the Base  Building
Drawings  or  Base  Building   Work).   Tenant  has  provided  to  Landlord  the
Tenant-approved space plans for the Premises (collectively referred to herein as
"Space Plans") prepared by Tenant's Architect, which plans are dated January 17,
2000;  Tenant  shall also have  Tenant's  Engineers  review  the Space  Plans on
Tenant's behalf for conformity to the Base Building Drawing. The


                                       1
<PAGE>

Space  Plans  shall  contain  information  specified  in  EXHIBIT 1 and shall be
sufficiently complete to permit Landlord and Landlord's Engineers to review such
drawings for the purpose of  conforming  the Space Plans with the Base  Building
Drawings  and for the purposes  described in Section 1.3 below.  The Space Plans
shall be prepared  by Tenant's  Architect  at  Tenant's  sole cost and  expense,
subject to Landlord's payment of the Allowance as hereinafter provided.

1.3 Within 5 business days after the Delivery  Date,  Landlord  shall review the
Space Plans and confer with Tenant concerning such review.  Tenant's  Engineers,
and  Landlord's  Engineers,  if  applicable,  shall  advise  Landlord and Tenant
whether the Base Building Work will have to be supplemented or modified in order
to allow  installation  of work shown on the Space  Plans.  If  Landlord or such
engineers  reasonably  determine that the Space Plans (i) are inconsistent  with
the Base Building Drawings; (ii) do not contain all of the information specified
in EXHIBIT 1 or are not sufficiently  complete to permit Landlord to review them
for the purposes set forth therein;  or (iii) indicate space usages inconsistent
with the  Permitted  Use set forth in the Lease,  Landlord  shall notify  Tenant
within such 5 business day period of Landlord's  determination setting forth the
specific reasons therefor, in reasonable detail. Thereafter, Tenant shall revise
the Space  Plans  accordingly  and  resubmit  them to  Landlord  and the  review
procedure  and time  frames  set forth  above  shall be  repeated.  Any delay by
Landlord in  responding  within the  applicable  periods or delays  arising from
errors by  Landlord or its  engineers  in such  review  process  shall be deemed
"Landlord  Delay" to the extent that such delay results in delaying  approval of
the Approved  Space Plans beyond the 15th day  following  receipt by Landlord of
the initial Space Plans; except for such delay, approval of Approved Space Plans
shall not delay the Commencement  Date under Section 2.4 below. When approved by
Landlord and Tenant,  the Space Plans shall be  acknowledged as such by Landlord
and Tenant  signing each sheet  therefor  and such  approved  drawings  shall be
deemed the "Approved Space Plans."

1.4 Tenant has provided Landlord with architectural working drawings prepared by
Tenant's  Architect  (the  "Architectural  Working  Drawings")  and  structural,
plumbing,  fire  protection,  mechanical  controls,  electrical  and life safety
engineering  drawings  prepared  by  Tenant's  Engineers  ("Engineering  Working
Drawings") for the Premises approved by Tenant for review by Landlord, which are
to be substantially in the form provided in EXHIBIT 1. The Architectural Working
Drawings shall be coordinated by Tenant's Architect with the Engineering Working
Drawings  prepared by Tenant's  Engineers  pursuant to Paragraph 1.3 above.  The
Architectural  Working Drawings and the Engineering  Working Drawings shall be a
logical extension of the Approved Space Plans.  Landlord shall have the right to
have a representative of Landlord attend Tenant's weekly construction  meetings.
Tenant shall have responsibility for any problems caused by any inconsistency of
the Architectural Working Drawings and the Engineering Working Drawings with one
another or with the Base Building  Drawings,  conflicts with building codes, and
any conflicts  between such drawings and field  conditions  disclosed to Tenant.
Landlord,  Landlord's Architect and Landlord's Engineers,  as applicable,  shall
review the Architectural  Working Drawings and the Engineering  Working Drawings
within 7 business  days after the Delivery Date and give notice if they discover
any  conflicts  with  the  Base  Building   Drawings  or  field   conditions  or
noncompliance with building codes within such period. If Landlord does not reply
within such period, it shall be presumed that Landlord has no objection thereto,
however,  such approval shall not limit  Landlord's  right to request changes in
the future in the event design errors are discovered  later (which request shall
be made as soon as practicable following such discovery);  however, Tenant shall
be obligated  only to make changes with regard to design  errors  identified  by
Landlord  after such 7 business  day period that affect the safety of the Finish
Work or that are required by  Applicable  Laws. If Landlord  notifies  Tenant of
such errors  (within the time period,  if  applicable),  Tenant shall revise the
Architectural  Working Drawings and the Engineering Working Drawings accordingly
and resubmit them to Landlord and the review  procedure set forth above shall be
repeated.  Delay caused by such  revisions  shall be deemed Tenant  Delay.  When
approved (or deemed  approved) by Landlord and Tenant,  such  drawings  shall be
deemed the "Final Working Drawings."

1.5  Changes  to the  Final  Working  Drawings,  except  for minor  changes  not
affecting  the Building  mechanical,  electrical  or life safety  systems or the
structure  of the  Building,  may be made only upon prior  written  approval  of
Landlord. Landlord shall respond (in writing or by oral communication thereafter
confirmed in writing) to all written requests for changes within 7 business days
of  Landlord's  receipt of the same.  If Landlord  does not respond  within such
period,  Landlord  shall be deemed to have  consented to the requested  changes.
Tenant shall provide Landlord with revised Final Working Drawings reflecting any
such changes as soon as reasonably  practicable.  Any delay in completion of the
Finish Work or


                                       2
<PAGE>

the Base  Building  Work which  results  from any such changes or the process of
approval or  disapproval  (other than caused by Landlord  Delay) shall be deemed
Tenant  Delay.  Landlord's  review of the  Space  Plans,  Architectural  Working
Drawings, Engineering Working Drawings or Final Working Drawings shall not imply
approval  by  Landlord  for their  completeness,  design  sufficiency,  or as to
compliance with the requirements of applicable  codes,  rules, or regulations of
any governmental agencies having jurisdiction thereof now in effect or which may
hereafter be in effect.

II.  Finish Work and Finish Allowance
2.1 Tenant agrees to execute  contracts for design and construction  services to
complete the Finish Work (the "Contract")  with  contractors and  subcontractors
reasonably  satisfactory  to Landlord  (collectively,  "Tenant's  Contractors").
Tenant and Tenant's  Contractors  will be required to adhere to the requirements
set  forth on  EXHIBIT  2  (collectively,  "Requirements").  The  Contract  will
incorporate  the provisions of the  Requirements or otherwise be consistent with
the  Requirements,  subject to changes as may be approved by Landlord.  Prior to
execution of the Contract, Tenant will provide a copy to Landlord. Landlord will
review the Contract for compliance  with the  Requirements  and advise Tenant of
Landlord's  approval or required changes within 10 business days of receipt;  if
Landlord  fails to  respond  within  such  period,  Landlord  shall be deemed to
approved such contract(s). Following such approval and the Delivery Date, Tenant
will promptly commence and proceed diligently to complete the Finish Work.

2.2 Tenant's Contractors and contractors employed by Landlord who are completing
work in the Building Complex  ("Landlord's  Contractors")  shall be obligated to
mutually cooperate and such Contractors will each conduct its respective work in
an orderly  fashion  and  manner so as not to  unreasonably  interfere  with the
other. Tenant's subcontractors with respect to all mechanical,  electrical,  and
fire protection work in the Premises will be the subcontractors used by Landlord
for  such  work  in  the  Building,  provided,  however,  if  Tenant  bids  such
subcontracts  and the bids of  Landlord's  subcontractors  are in  excess  of 5%
higher  than the next  highest  bid,  Landlord  shall  either  not  unreasonably
withhold  approval  of such  other  subcontractor(s)  or  require  Tenant to use
Landlord's  subcontractor(s)  but pay to Tenant (as  additional  Allowance)  the
difference  between such bids. If requested by Tenant,  Landlord shall supervise
construction  by Tenant's  Contractors,  in which case Tenant shall pay from the
Allowance to Landlord a construction  supervision and management fee equal to 5%
of the total costs of construction of the Finish Work;  otherwise,  Tenant shall
be responsible for supervising Tenant's  Contractors,  but Tenant shall also pay
from the Allowance to Landlord a  construction  coordination  fee equal to 1% of
the total costs of construction of the Finish Work.

2.3 Tenant assumes full responsibility for Tenant's Contractor's  performance of
all  work  including  compliance  with  Applicable  Laws,  and for all  Tenant's
Contractors' property, equipment, materials, tools or machinery placed or stored
in the  Premises  during  the  completion  thereof  (subject  to the  provisions
regarding Builder's Risk insurance).  All such work is to be performed in a good
and workmanlike manner consistent with first class standards.

2.4 Landlord  has notified  Tenant that  Landlord has  determined  that the Base
Building Work has been Substantially Completed.  "Substantially Completed" means
that all of the following have occurred: (i) Landlord has performed or completed
substantially  all of the Base  Building  Work  which is the  responsibility  of
Landlord to complete in accordance with the Base Building Drawings and this Work
Letter,  except only punch list items which: (1) do not substantially  interfere
with Tenant's ability to perform and complete Tenant's Finish Work, otherwise to
complete  improvements to the Premises to be made by Tenant or occupy or use the
Premises,  and (2) which are reasonably  projected to be completed  prior to the
Rent  commencement  dates  provided  in Section 4 of the Lease for the  affected
areas; and (ii) all approvals, certificates of occupancy and permits (other than
Tenant's  business  licenses and  certificates  of occupancy  pertaining  to the
completion of Tenant's  Finish Work),  and those permits and approvals  from the
appropriate  governmental  authorities  pertaining  to the Base Building Work or
other  improvements  to be  constructed  by Landlord  required for the legal and
practical  occupancy  of the Premises  (except for such  permits  which by their
terms cannot be issued until Tenant's  Finish Work is completed);  and (iii) the
Landlord's  Architect  certifies  in writing to Tenant that the  portions of the
Premises   constituting  Base  Building  Work  and  other   improvements  to  be
constructed by Landlord are substantially complete; and (iv) the construction of
Common Areas, including,  without limitation,  lobbies,  corridors,  loading and
parking facilities and the Base Building Systems serving the Building shall have
been substantially completed and so certified by


                                       3
<PAGE>

Landlord's  Architect and approved by the appropriate  governmental  authorities
(to the extent  required);  and (v) Landlord has effected removal of rubbish and
debris  and  Landlord's  (and  its  contractors')   construction  materials  and
equipment  to the  extent  necessary  to  permit  Tenant  access  and use of the
Building and Premises for  commencing  its Tenant  Finish Work in the  Premises.
Following the Delivery  Date and prior to Tenant's  Contractors  commencing  the
Finish Work, the  representatives  of Landlord and Tenant shall jointly  inspect
the  Premises  with  Landlord's  Architect  and  develop a list of items of Base
Building Work that have not been completed (the items set forth on such list are
referred to herein as "Punch List Items"). In the event of a dispute, Landlord's
Architect and Tenant's  Architect shall mutually resolve such dispute and if the
Architects cannot agree upon a resolution,  the Architects shall jointly appoint
an independent  architect whose  determination  shall be binding on the parties.
The date on which Landlord  delivers a fully executed  original of this Lease to
Tenant is referred to as the  "Delivery  Date."  Following  the  Delivery  Date,
Landlord shall complete the Punch List Items with reasonable  diligence and in a
manner so as to minimize delay or interference with the completion of the Finish
Work by Tenant and Tenant shall  commence  completion of the Tenant Finish Work,
while being  responsible for repair of damage caused by Tenant's  Contractors in
the Building or Premises. Following the Delivery Date, Tenant is responsible for
the diligent  completion of all finish work substantially in accordance with the
Working Drawings (the "Finish Work"),  at its sole cost and expense,  subject to
Landlord's payment of the Allowance.  Tenant's use and occupancy of the Premises
following the Delivery  Date, as well as related use of the Building  Complex in
conjunction  with such use, is subject to all of the terms and provisions of the
Lease  (except for Tenant's  obligation  to pay Base Rent and  utilities,  which
shall be governed by the  provisions  of Section 4 and 7 of the Lease;  it being
understood that no Base Rent or utilities  obligations  shall commence until the
Rent  commencement  dates  provided  in Section 4 of the Lease).  Following  the
Delivery Date, to minimize interference or delay in the completion of the Finish
Work and Punch List  Items,  Tenant  will  cause  Tenant's  Contractors  to: (i)
conduct work so as not to  unreasonably  interfere  with any other  construction
occurring in the Building Complex  (including Punch List Items or occurring with
respect to the adjacent  building  known as Worldgate  Plaza I; (ii) comply with
the  Requirements;   and  (iii)  reach  reasonable   agreement  with  Landlord's
Contractors as to the terms and conditions  for hoisting,  systems  interfacing,
and  use of  temporary  utilities.  Landlord  shall  likewise  cause  Landlord's
Contractors  to : (i)  conduct  work so as not to  unreasonably  interfere  with
Tenant's  Contractors  completion of Finish Work;  (ii)  cooperate with Tenant's
Contractor's to permit their compliance with the  Requirements;  and (iii) reach
reasonable  agreement  with Tenant's  Contractors as to the terms and conditions
for hoisting,  systems interfacing,  and use of temporary utilities. There shall
be no charge for Tenant's and Tenant's Contractors access to the Building or for
use of  elevators  or hoists  and  Landlord  shall  permit  Tenant to  operate a
temporary  construction office on a floor of the Premises following the Delivery
Date or in a location  designated by Landlord elsewhere in the Building Complex,
to the extent  space is available  for such  purpose and  operation is permitted
under  applicable  codes  and  will  not  limit  Landlord's  ability  to  obtain
inspection approvals under applicable codes.

2.5 Landlord will pay the cost of the Finish Work as substantially  completed in
accordance  with the Final  Drawings  (including  the cost of preparation of the
Space Plan and Final  Drawings and Landlord's  review  thereof) in the amount of
$2,457,751.00  (the  "Allowance").  Landlord  shall make progress  payments on a
monthly basis as portions of the Finish Work is completed  following  request of
Tenant in accordance with Section 2.6. Finish Work Costs in excess of the Finish
Allowance ("Excess Costs") will be at Tenant's sole cost and expense and will be
paid promptly by Tenant, subject to the provisions of this Work Letter. Upon the
execution hereof,  Landlord shall pay to Tenant $8,058.20 as reimbursement for a
portion of the costs incurred by Tenant for Tenant's Architect's programming and
test fit design work,  which amount shall be in addition to the  Allowance  (the
"Design Allowance").

2.6 The Allowance is to be expended solely for the benefit of Landlord; that is,
the  Allowance   will  be  expended   only  to  pay  for  design,   engineering,
installation,  and construction of the Finish Work which under the Lease becomes
the property of Landlord upon  installation and for cabling and wiring,  but not
for movable furniture,  equipment, and trade fixtures not physically attached to
the  Premises.  Not more  than  $250,000.00  of the  Allowance  shall be paid to
Tenant's  Architect  and  Tenant's  Engineer  for  planning,  architectural  and
engineering costs (in addition to the Design Allowance). Any of Landlord's costs
and expenses payable to Landlord,  required to be paid by Tenant under this Work
Letter  will  also be paid  out of the  Allowance.  Prior to  Tenant  commencing
construction  of the Finish Work,  Tenant shall provide  Landlord with notice of
the total  estimated  cost of all  Finish  Work.  As  design,  engineering,  and
construction work is completed and


                                       4
<PAGE>

Tenant receives  invoices  therefor,  Tenant will submit requests for payment to
Landlord not more frequently than monthly,  along with  appropriate lien waivers
(substantially in the forms attached hereto as EXHIBIT 3) and such other related
documentation  as Landlord  reasonably  requires.  On a monthly basis  following
receipt of such  documentation  (with such payment being made by the 30th of the
month if all required  documentation  is received by Landlord by the 5th of such
month),  Landlord  will pay the  amounts  requested  by  delivery  to  Tenant of
Landlord's  check(s)  payable to Tenant  or, at  Landlord's  option,  payable to
Tenant  and  Tenant's  Contractors  jointly;  provided,  however,  that  if  the
estimated  costs of completing the Finish Work exceeds the  Allowance,  Landlord
shall have the right to disburse the Allowance on a percentage  basis,  equal to
that  percentage  of the  invoiced  work that  equals  the  percentage  that the
Allowance  constitutes of the total estimated  costs of the Finish Work.  Unless
otherwise  agreed by Landlord and Tenant in writing and subject to delays beyond
Tenant's reasonable control, if any portion of the costs to be reimbursed by the
Allowance has not been  requested by Tenant or will be requested for Finish Work
that is ongoing as of December  31, 2000 (which  deadline  shall be extended for
Finish  Work  ongoing  at the  time of such  deadline)  such  amounts  shall  be
forfeited by Tenant.

2.7  Landlord  will,  during  completion  of the  Finish  Work  and  immediately
thereafter,  reasonably  cooperate in the  balancing of the Building HVAC system
serving  the  Premises.  Landlord  shall  pay for  costs of  balancing  the Base
Building Work portions of the HVAC system  (including the central fans discharge
and the perimeter  heating/cooling  zone) and Tenant shall pay for balancing the
portions of the system within the Premises.

2.8  Subject to the  mutual  waiver in Section  18.6 of the Lease,  Tenant  will
indemnify,  defend and hold harmless Landlord,  Building Manager, and Landlord's
Contractors from and against liability, costs or expenses,  including attorney's
fees on account of damage to the person or property  of any third party  arising
out of, or resulting from the performance of the Finish Work, including, but not
limited  to,  mechanics'  or other  liens or claims  (and all  costs  associated
therewith),  subject to  Landlord's  obligation  to disburse  the  Allowance  in
accordance with the foregoing provisions. Tenant will also repair or cause to be
repaired  at its expense all damage  caused to the  Premises or the  Building by
Tenant's  Contractors  or its  subcontractor,  subject to the  mutual  waiver in
Section  18.6 of the Lease  and the  provisions  for  Builder's  Risk  insurance
provided in this Work Letter and Exhibits. Further, Landlord will have the right
as  described  in  Section  12.1 of the Lease to post and  maintain  notices  of
non-liability.  Subject  to the  mutual  waiver in  Section  18.6 of the  Lease,
Landlord  will   indemnify,   defend  and  hold  harmless  Tenant  and  Tenant's
Contractors from and against liability, costs or expenses,  including attorney's
fees on account of damage to the person or property  of any third party  arising
out of, or resulting  from the  performance  of the Base Building Work and other
improvements  and work  performed  by Landlord  and  Landlord's  Contractors  on
Landlord's behalf,  including,  but not limited to, mechanics' or other liens or
claims (and all costs associated therewith).  Landlord will also repair or cause
to be repaired at its expense all damage  caused to the Premises or the Building
by Landlord 's Contractors or its  subcontractors,  subject to the mutual waiver
in Section 18.6 of the Lease and the  provisions  for Builder's  Risk  insurance
provided in this Work Letter and Exhibits.

2.9 Tenant agrees to submit to Landlord  within 60 days following  completion of
all work one  reverse  mylar  sepia  and two  blueprint  copies  of the as built
drawings (the Final Drawings  showing all changes  thereon as marked by Tenant's
Contractors in the field to show field modifications).

2.10  Notwithstanding  any  provision  herein or in the  Lease to the  contrary,
Tenant's Rent obligations and other  obligations will not be delayed or extended
by any delay in completion of the Finish Work;  provided,  however,  that Tenant
shall be entitled to an  abatement  of Base Rent for any portion of the Premises
as to which Tenant's  completion of Finish Work for such portion of the Premises
is delayed by Landlord Delay or by a casualty  occurring after the Delivery Date
that is covered by the Builder's  Risk insurance  carried by Landlord.  The term
"Landlord Delay" means any delay designated as such in this Work Letter or delay
in the  preparation,  finalization  or  approval  of the  Space  Plans,  Working
Drawings or  completion  of the Finish Work caused by  Landlord's  or Landlord's
Contractors'  failure to perform its or their obligations under this Work Letter
within the time limits set forth herein that cause a delay in the  completion of
the Finish Work,  including,  without  limitation,  as a result of  interference
caused by  Landlord  or  Landlord's  Contractors  (to the extent  not  permitted
herein);  Tenant shall provide  notice to Landlord as soon as Tenant  determines
that  Landlord  Delay has  occurred.  All delays other than  Landlord  Delay are

                            EXHIBIT 2 TO WORK LETTER

                      LANDLORD REQUIREMENTS OF THE CONTRACT

The Contract  will be subject to review and  approval of Landlord in  accordance
with the Work Letter and will fully incorporate the following provisions. In the
event of any conflict  between any provisions of the Contract and the provisions
below, the provisions below will control.

1. The  Contract  will be in writing  and will  cover all  aspects of the Finish
Work. No Finish Work will be performed  except  pursuant to the Contract.  Fully
executed  copies of the Contract  will be  delivered  to  Landlord.  If Landlord
determines that the Contract does not comply with the provisions hereof, it will
immediately be corrected and no work will be commenced in the Premises until the
deficiencies  have been  corrected.  Any  delays in  completion  resulting  from
modifications  (except as  required by  Landlord  Delay) will be Tenant  Delays.
Following  delivery of a copy of the  Contract to Landlord  and its approval (or
deemed approval),  no material modification will be effective unless and until a
copy thereof has been delivered to Landlord for its review.

2. Changes in the Final  Drawings will be made only upon prior written  approval
(or deemed approval) of Landlord (to the extent required under and in accordance
with Section 1.5 of the Work Letter).

3. Scheduling of Finish Work: The Contract will obligate Tenant's  Contractor to
perform  Finish Work in  accordance  with time  schedules  acceptable to Tenant,
Tenant's  Contractor and Landlord  (which approval shall be based on consistency
with Landlord's schedule for completion of the Base Building Work). Any schedule
proposed by Tenant's  Contractor will be based upon Tenant's Contractor applying
its best efforts to the Finish Work.

4. Tenant's  Contractor will not knowingly perform Finish Work inconsistent with
the Final Working Drawings which will result in a lesser quality installation or
provide  inferior  performance  than that established by the base shell and core
drawings and specifications  covering similar work items. Landlord will have the
right at any time during the performance of Finish Work or thereafter to require
replacement and reconstruction at Tenant's Expense of Finish Work not conforming
to the standards and specifications in the Final Drawings.

5.  Tenant and  Tenant's  Contractor  will give all  notices and comply with all
laws, ordinances, rules, regulations and orders of any public authority relating
to the  performance of the Finish Work. If either party observes that any Finish
Work is at variance  with any  applicable  codes,  ordinances,  laws,  rules and
regulations (collectively, "Applicable Laws"), it will promptly notify the other
party and Landlord in writing,  and necessary changes will be made by Tenant. If
Tenant's  Contractor  performs  any  Finish  Work that it knows is  contrary  to
Applicable  Laws,  and fails to deliver  prior  notice to Tenant  and  Landlord,
Tenant's Contractor will assume full  responsibility  therefor and will bear all
costs  attributable  to repair,  replacement  or  correction.  Tenant,  Tenant's
Contractor and its subcontractors will comply with Federal,  State and local tax
laws, social security acts,  unemployment  compensation acts and such other acts
and laws as are applicable to the performance of Finish Work.

6. All risk of loss to all  property  of  Tenant,  Tenant's  Contractor  and its
subcontractors  will be the sole  responsibility of Tenant,  Tenant's Contractor
and its  subcontractors,  and  Landlord  will have no  responsibility  therefor,
subject to Builder's  Risk insurance on the Finish Work to the extent carried by
Landlord in accordance with Section 2.14 of the Work Letter.


                                       1

7. The following insurance requirements will be complied with:

     Finish Work,  whether such work is  performed by Tenant's  Contractor,  its
     subcontractors,  or by anyone for whose acts such  parties may be liable as

     appropriate "umbrella" policy):

<PAGE>

               Automobile Property Damage:
               $500,000 each person

     b. Unless Landlord  retains  Builder's Risk insurance on the Finish Work in
     accordance with Section 2.14 of the Work Letter, Tenant or Tenant's general
     contractor  shall carry  Builder's  Risk  insurance  covering the completed
     value of the Finish Work which will afford coverage against "all risks" for
     physical loss or damage.

     c.  Cancellation  - All  such  insurance  will be  carried  with a  company
     reasonably  satisfactory  to Landlord and Tenant and the  liability  policy
     will name Landlord and Tenant and their  employees and agents as additional
     insured  parties.  Each policy will provide that it will not be canceled or
     altered  except after 15 days prior written  notice to Tenant and Landlord,
     and the certificate of insurance will so state.

     d. Policy  Termination - Tenant's  Contractor and each  subcontractor  will
     maintain all insurance  required  hereunder during the term of the Contract
     and for a period ending one year after the date of completion of all Finish
     Work done pursuant to the Contract to the extent such  insurance is written
     in a "claims made basis."

     e. Policies - Prior to commencement of work by Tenant's Contractor, it will
     deliver one copy of the policies or certificates  evidencing such insurance
     to Tenant  and  Landlord.  Such  policies  must be  approved  by Tenant and
     Landlord prior to commencement of work. Notwithstanding the above, Landlord
     may  require  greater  coverage  or larger  limits by serving  notice  upon
     Tenant. Without the written consent of Landlord, Tenant's Contractor agrees
     that it will not  allow any  subcontractor  to  commence  work  within  the
     building until such subcontractor has obtained the required insurance.

     f. Umbrella Liability  Insurance - Umbrella liability insurance with limits
     of  liability  for claims of bodily  injury,  personal  injury and property
     damage  liability not less than $10,000,000 each occurrence and $10,000,000
     aggregate.

     g. Waiver of Subrogation - Landlord,  Tenant and Tenant's  Contractor  will
     waive all rights  against  each other,  and their  respective  contractors,
     subcontractors and  sub-subcontractors,  agents and employees,  for damages
     caused by fire or other perils  covered under the Builder's  Risk insurance
     policy on the Finish Work.

9. Tenant's  Contractor  will  indemnify,  defend,  and hold harmless Tenant and
Landlord and their  respective  representatives,  agents and employees  from and
against all claims, damages, losses and expenses,  including, but not limited to
reasonable  attorney's fees, arising out of or resulting from the performance of
Finish Work or Tenant's  Contractor's  failure to perform in accordance with the
Contract  (but  specifically  excluding the Finish Work itself and the Building)
which are:  a) caused in whole or in part by any  negligent  act or  omission of
Tenant's Contractor,  any subcontractor,  anyone directly or indirectly employed
by any of them or anyone for whose acts any of them may be liable, regardless of
whether or not such claim,  loss, damage or expense is caused in part by a party
indemnified hereunder, and b) attributable to bodily injury,  sickness,  disease
or death, or destruction of or damage to tangible property including loss of use
resulting from any of the foregoing acts.


<PAGE>

Tenant's  indemnification  obligation under this Paragraph 9 will not be limited
by any  limitation  on the amount or type of damages,  compensation  or benefits
payable  by  or  for  the  Contractor  or  any  subcontractor   under  workmen's
compensation acts, disability benefit acts or other employee benefit acts.

10.  Tenant's  Contractor  and Tenant  will agree that while  Landlord  may make
available  to  Tenant's  Contractor  for  incorporation  into  the  Finish  Work
materials previously purchased by Landlord,  Landlord is not the manufacturer of
such materials nor is it the commercial supplier of such materials. Accordingly,
Tenant  and  Tenant's  Contractor  will agree that if either one or both of them
have any claim with  respect to any of such  materials  supplied by Landlord for
incorporation  into the Finish Work,  whether such claims  relate to any alleged
breach of an express  warranty or an implied  warranty or otherwise,  any claims
against  Landlord  whether  directly or by way of defense,  counterclaim,  cross
claim or  offset  are  waived  and  released  and such  claims  will be  brought
exclusively  against  the person or entity  from whom  Landlord  purchased  such
materials or against the  manufacturer.  Landlord will execute such documents as
may be reasonably  necessary to assign any rights  Landlord would otherwise have
against a supplier or manufacturer.

11.  Landlord or Tenant may require  Tenant's  Contractor to provide payment and
performance  bonds for any or all  Finish  Work,  such bonds to be  provided  at
Tenant's expense (subject to reimbursement  under the Allowance).  Any bond will
be requested and provided prior to commencement of Finish Work.

12.  If  Tenant's  Contractor  is  adjudicated  a  bankrupt,  or makes a general
assignment  for the benefit of its  creditors,  or if a receiver is appointed on
account  of  Tenant's  Contractor's   insolvency,   or  if  Tenant's  Contractor
persistently  or  repeatedly  refuses or fails,  except in cases  where delay is
justified,  to supply enough properly  skilled workmen or proper materials or if
Tenant's  Contractor  persistently  disregards  Applicable Laws, or otherwise is
guilty of a substantial  violation of a provision of the  Contract,  Tenant may,
without  prejudice to any right or remedy and after giving  Tenant's  Contractor
and its surety, if any, 7 business days' written notice,  terminate the Contract
and take possession of all materials,  equipment,  tools, construction equipment
and machinery  owned by Tenant's  Contractor  and will  thereafter  complete the
Finish Work by whatever  method it may deem  expedient.  In such case,  Tenant's
Contractor will not be entitled to receive any further payments until completion
of all Finish Work;  provided,  however,  that Tenant's actions will not release
Tenant's  Contractor from any obligations to Tenant arising from its performance
or nonperformance prior to the date of such termination.  Following  completion,
Tenant will pay  Tenant's  Contractor  an amount  equal to the  aggregate of the
amounts actually due under the Contract at the time of the termination, less the
cost to Tenant of completing the Finish Work.

13.  Prior  to  commencement  of  any  Finish  Work  in the  Premises,  Tenant's
Contractor will give written notice to Landlord and Tenant of the date work will
commence.  If a subcontractor or materialman files a mechanics' lien as a result
of  performing  Finish Work pursuant to the Contract,  then,  provided  Tenant's
Contractor has been paid for such work,  Tenant's  Contractor will indemnify and
defend Tenant and Landlord from said lien and will,  when requested by Tenant or
Landlord,  furnish (as Landlord or Tenant may specify)  either a bond sufficient
to discharge  the lien,  deposit in an escrow  approved by Landlord and Tenant a
sum  equal  to 150%  of the  amount  of such  lien or  obtain  for  Landlord  an
endorsement  through  Landlord's  title policy  insuring  against loss or damage
resulting from such lien. Subject to any restrictions of Landlord's Mortgagee on
the Building,  Tenant's Contractor may, in cooperation with Landlord and Tenant,
contest the validity of a mechanics' lien,  including the right to prosecute any
appeals so long as during the pendency of any contest,  Tenant's Contractor will
effectively  stay any official or judicial sale of the Building,  upon execution
or  otherwise,  and so long as Tenant's  Contractor  immediately  pays any final
judgment entered and procures record satisfaction thereof. If Tenant or Landlord
is a party to any such contest,  or any other action  resulting  from or arising
out of the  performance  of the Finish Work,  Tenant's  Contractor  will pay all
legal fees and other costs and expenses

<PAGE>

incurred by Landlord and Tenant in such action. If Tenant's  Contractor fails to
provide a bond,  cash escrow or title  endorsement,  or otherwise fails to fully
satisfy  and obtain  the  release of a lien in  accordance  with the  provisions
hereof,  Tenant's Contractor will be obligated to refund Tenant or Landlord,  as
the case may be, all monies that the latter may pay in discharging any such lien
including costs and reasonable  attorneys' fees incurred in settling,  defending
against, appealing or in any other manner dealing with any such lien.

14.  Tenant's  Contractor  will  warrant  and agree at its expense to correct or
cause to be corrected any defects in the Finish Work (including, but not limited
to,  defects  due  to  defective  workmanship  or  materials  whether  supplied,
installed or performed by Tenant's  Contractor or any subcontractor or supplier)
which  occur  within  one  year  after  Tenant's  Contractor  has  substantially
completed the Finish Work,  including  completion of all punchlist items, or for
such  longer  period  as may be  set  forth  in  the  Final  Drawings.  Tenant's
Contractor will require a similar warranty in all subcontracts, and will deliver
to Landlord and Tenant, together with appropriate assignments,  if required, all
warranties of subcontractors  and suppliers.  All warranties will extend to both
Landlord  and Tenant,  as their  respective  interests in such Finish Work exist
pursuant to the Lease.

15. Tenant's  Contractor  will: (a) comply with all reasonable rules relating to
construction  activities in the Building  promulgated  by Landlord or Landlord's
Contractor;  (b) be responsible  for reaching  agreement with Landlord as to the
reasonable  conditions for use of the  elevators,  systems  interfacing,  use of
temporary  utilities,  access to the Premises and use of truck docks and storage
areas (without charge).

16.  Landlord shall make available  hoisting,  systems  interfacing,  and use of
temporary  utilities as is customary in construction of similar buildings in the
suburban Washington, D.C. area, subject to Landlord's schedule for completion of
the Base Building Work.

17.  Landlord  and  Landlord's  Contractor  may,  from time to time,  inspect or
perform work within the Premises. Such inspections or work will not unreasonably
conflict  with  Tenant's   Contractor's  work.  Landlord  may  suspend  Tenant's
Contractor's  work in the Premises if such work,  in the  reasonable  opinion of
Landlord or of  Landlord's  Contractor,  presents a danger to life,  safety,  or
property, or in an emergency situation.

18.  Tenant  will give  Landlord  reasonable  prior  notice of all  inspections,
punchouts and other reviews during the course of  construction  so that Landlord
may observe  such  events.  Landlord  will be likewise  informed of all Building
Department  inspections  and  requirements  for issuance of the  Certificate  of
Occupancy for the Premises.  Landlord's  observation of any such events will, in
no event be construed or  interpreted as a review or approval by Landlord of any
such  work  nor  will  it  prevent  Landlord,  if it  thereafter  discovers  any
deficiency in such Work, from requiring correction.  Tenant's Contractor will be
solely  responsible for obtaining a certificate of occupancy (or its equivalent)
for the  Premises (as  distinguished  from a similar  certificate  to the extent
required  for the Base  Building  Work) and will submit to Landlord the original
prior to  Tenant's  occupancy  of the  Premises  for the  purpose of  conducting
business.

19.  Landlord's  Engineer or other agent will have the option of  reviewing  all
equipment  and materials to be used in the  construction  of the Finish Work for
consistency  with Final Working  Drawings and all work prior to Tenant  move-in.
Such review will in no event constitute  approval by Landlord and Landlord shall
use reasonable efforts to minimize any delay arising from such reviews.

20. Tenant will promptly  furnish  Landlord a copy of the building permit issued
to Tenant's Contractor after issuance.


<PAGE>

21.  Tenant's  Contractor will not store materials or supplies in or outside the
Building (other than within the Premises) without the prior approval of Landlord
or Landlord's Contractor.

22.  All  deliveries  except  hand-held  items  must be taken to the  floors via
elevator(s) designated by Landlord for such purpose.

23. Tenant's Contractor will provide at all times direct supervision of all work
being performed for Tenant.

24.  Tenant's  Contractor  will  cooperate  with  Landlord in  disposing  refuse
resulting from the Finish Work. This may include the use of Landlord's  dumpster
and a proration of charges  associated with such use or at Landlord's  option at
Tenant's  expense the  placement of Tenant  Contractor's  dumpster at a location
reasonably specified by Landlord.

25. Tenant's Contractor will acknowledge that the work to be performed by it for
Tenant is also for the direct benefit of Landlord.  Landlord will have the right
to pursue in its own name directly  against  Tenant's  Contractor  any rights or
remedies including, without limitation, claims for damages granted to Tenant.

If any legal  action or  arbitration  proceeding  is  commenced  to enforce  the
provisions  of the  Contract  or to recover  damages as a result of the  alleged
breach of the  provisions  thereof,  the  prevailing  party will be  entitled to
recover  all  reasonable  costs  incurred  in  connection  therewith,  including
attorneys' fees.

The  Contract  will be  construed  in  accordance  with the laws of the State of
Virginia  Subject to Paragraph 26, any  litigation or other  proceeding  will be
