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.

                                       8

         5.3.  Bridge 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,  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

                                       13
<PAGE>

                           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

                                       17
<PAGE>

                  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

         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.

19.      GENERAL PROVISIONS

         19.1.    NO THIRD-PARTY BENEFICIARIES.  This Agreement shall not confer

                  may  assign  either  this  Agreement  or any  of  its  rights,
                  interests,  or obligations hereunder without the prior written

                                  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
<PAGE>

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:

              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.

                           Affiliates of Bridge Parent (the "OA NETWORK"),

                  (b)      that  portion  of a global  data  collection  network
                           located   in  the   Jurisdiction   (the   "COLLECTION
                           NETWORK") and

                  (c)      that  portion of a global data  distribution  network
                           located  in  the  Jurisdiction   (the   "DISTRIBUTION
                           NETWORK"),

                           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 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.

                                       7

         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.

8.       TERMINATION BY SAVVIS

         8.1.     SAVVIS shall have the right to terminate this Agreement if:

                  (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.

                                       10
<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

                                       11
<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

                           filing  and of filing  any  subsequent  modifications

                  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

                                       14
<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

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.

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
                  assigns.]  [Except as  expressly  provided in this  Agreement,
                  nothing in this  Agreement will create or confer any rights or
                  other benefits on or in favor of any person who is not a party

                  referred to herein)  constitutes the entire agreement  between

                  agreements,  or  representations  by or between  the  parties,
                  written or oral,  to the extent they related in any way to the

                  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.

                                  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

                  subsidiaries  of  Telerate  which  will  be  involved  in  the
                  operation or ownership of the Acquired Network Facilities.

                  "TRANSITION  PERIOD" has the meaning  assigned to such term in
                  Section 6.3 of this Agreement.

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
                  Telerate,  Affiliates  of Telerate or any party  making use of
                  the   Networks   through   Telerate  the   following   managed
                  packet-data  transport  networks,   including  the  operation,
                  management and maintenance thereof:

                  (a)   a   global    office-automation    network,    providing
                        connectivity  between the offices of Telerate and 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 Telerate'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 Telerate 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,  Telerate shall be
                  entitled to receive,  upon written  request by Telerate within

                                       5
<PAGE>

                  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 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
                  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  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
<PAGE>

         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.

                                       15
<PAGE>

         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

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

                  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
                           Network Facilities); and

                                       19

                  (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 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
                  assigns.

         19.2.    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.

         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.

                  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

         8.1      SAVVIS shall have the right to terminate this Agreement if:

                  (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.

                                       34
<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.

<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

                                       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.

         17.1.    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.

19.      GENERAL PROVISIONS

                  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 benefits on or in favor of any person who is not a party

                  referred to herein)  constitutes the entire agreement  between

                  agreements,  or  representations  by or between  the  parties,
                  written or oral,  to the extent they related in any way to the

                  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.

                  owed by Bridge to SAVVIS  under this  Agreement,  the  Network
                  Services Agreement, or otherwise.

                  hereof.

         5.2.     The term of this Agreement shall automatically  terminate upon

6.       TERMINATION BY SAVVIS

         6.1.     SAVVIS shall have the right to terminate this Agreement,  with
                  no  liability  to  Bridge  other  than for  charges  (less any
                  applicable  credits)  for  Services  provided  prior  to  such
                  termination, if:

                  (a)      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;
                           or

                  (b)      Bridge   becomes  the  subject  of  a  voluntary   or
                           involuntary bankruptcy, insolvency, reorganization or
                           liquidation  proceeding,  makes an assignment for the

                           to pay debts when due.

         6.2.     In the event that SAVVIS  exercises  this option,  Bridge will
                  continue to provide the Services in accordance with the terms,
                  conditions  and rates  herein  for a period of up to 12 months
                  after the effective date of termination.  If the Services have
                  not  completely  transitioned  from  Bridge  after 12  months,
                  Bridge will provide the Services at Bridge's then current list
                  rates.  Bridge and its successor  will  cooperate  with SAVVIS
                  until  the  Services  are   completely   migrated  to  another
                  provider.

                           date on which  such  payment  is due and  Bridge  has
                           provided SAVVIS with written notice thereof, provided
                           that  SAVVIS  shall  have 30 days  from  the  time it
                           receives  such notice from  Bridge of  nonpayment  to
                           cure any such default; or

                   (b)     SAVVIS   becomes  the  subject  of  a  voluntary   or
                           involuntary bankruptcy, insolvency, reorganization or
                           liquidation  proceeding,  makes an assignment for the

                   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
                   serve as SAVVIS'  point-of-contact for all matters concerning
                   its performance under this Agreement.

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
                  the  parties and their  respective  successors  and  permitted
                  assigns.

         16.2.    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.

         16.3.    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.

         16.4.    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.

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