requested by Bridge.  Sprint shall  provide  written  recommendations  to Bridge

14.      Access Management.

         (a) Sprint shall order and manage on Bridge's  behalf  access  services
for use in  connection  with the Products  and  Services.  Sprint shall  utilize

("ACF") and Central Office Connection ("COC") charges waived. Sprint will review
access rates annually.  Sprint will only pass through to Bridge any decreases in
Tariff 8 rates,  but shall not pass through any  increases.  For rates that have
decreased, Sprint will reprice at the then current Tariff 8 rates less 15%. Once
the SIA Local Access Services  contract is signed,  Bridge may take advantage of
the SIA  pricing if TCG  provides  the  access.  However,  Bridge may use access
pricing  from only one  contract,  i.e.,  either this  contract or the SIA Local
Access Services contract. If SIA access pricing is selected,  non-SIA sites will
be  charged at  current  Sprint  Tariff 8 rates and ACF and COC shall be waived.
(Bridge  shall  also have the option of  choosing  Sprint's  Coordinated  Vendor
Billed  Access  ("SCVBA")  service at the price  specified in  Attachment  B. If
Bridge selects this option,  Sprint act's as Bridge's  agent to order,  test and
install access services, but the access provider bills Bridge directly.)

         (b) Bridge shall supply  Sprint with letters of agency to permit Sprint
to act on Bridge's behalf for purposes of ordering and managing access services.
The access  provider  will invoice  Sprint,  and Sprint will invoice  Bridge for
access services.

         (c) Sprint shall use due care to (i) monitor, direct and supervise such
access  provider's  performance  (including  conducting fault  isolation);  (ii)
enforce any warranties and other  assurances of performance  obtained from it by
Sprint  pursuant to tariff or otherwise;  or (iii) report promptly to Bridge any
actual or threatened failure of performance by such access provider that does or
could  reasonably  be  expected  to affect  adversely  in any  material  respect

requirements of this Agreement.

otherwise  provided herein,  Bridge shall surrender the equipment to Sprint upon
the termination of this Agreement.

                  (ii) Bridge  shall be liable for damages to the  Products  and
Services  caused by the  negligence  or willful  acts or  omissions  of Bridge's
officers,  employees,  agents  or  contractors;  for the loss  through  theft or
vandalism  of the  Products  and  Services at the  Installation  Sites;  and for
damages to Products and Services  caused by the use of equipment or supplies not
provided hereunder or otherwise authorized by Sprint.

                  (iii) Bridge shall neither permit nor assist others to use the
Products  and  Services  for any  purposes  other  than that for which  they are
intended;  fail to maintain a suitable  environment  as specified  Sprint in the
applicable  schedule;  or alter,  tamper with, adjust or repair the Products and
Services. Any such alteration,  tampering,  adjustment or repair by Bridge shall
relieve  Sprint  from any  liability  or  obligation  hereunder  (including  any
warranty  or  indemnity  obligation)  relating  to  the  affected  Products  and
Services,  and Bridge shall be liable to Sprint for any documented  direct costs
incurred by Sprint as a result of such actions.

the use of the Sprint network by other Sprint  customers or authorized  users in
violation of the law or in support of any unlawful act.

16.      Rights and Obligations of Sprint.

         (a) Program Manager.  Sprint shall assign a representative  to serve as
Bridge's  point-of-contact for all matters concerning its performance under this
Agreement.

         (b)  Provision  of the  Products and  Services.  Sprint shall  install,
operate,  maintain and manage the Products and Services at the Installation Site
designated by Bridge in accordance with the Performance Specifications and other
terms of this  Agreement.  Sprint  shall  install  the cable that  connects  the
Products and Services to Bridge servers at such Installation  Sites to achieve a
Working System.  Bridge may at any time add, delete,  relocate or, with Sprint's
consent,  modify any  Product or  Service.  The  installation  interval  for any
addition or relocation shall be determined by agreement of the parties.

as is  reasonably  necessary to provide the Products and Services in  accordance
with this  Agreement,  provided that Sprint  personnel shall comply at all times
with  Bridge's  reasonable  security  requirements.  Bridge shall have the right
immediately  to terminate the right of access of any Sprint  personnel to any or
all Installation  Sites should Bridge determine in its sole discretion that such
termination  is in  Bridge's  best  interest,  provided  that  Bridge  shall not
exercise this right on grounds  unrelated to job performance or in a manner that
obliges  Sprint  to  commit  any  unlawful  act.  Unless  Sprint  knew or should
reasonably have known that particular  Sprint  personnel would be barred from an
Installation 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 Sprint to deploy substitute  personnel,  provided
that Sprint  shall use its best efforts to deploy such  substitute  personnel as

         (d)      Insurance.

                  (i) At all times  during  the term of this  Agreement,  Sprint
shall maintain for itself, its officers,  employees, agents, and representatives
the  following:  (i) all insurance  coverage  required by federal and state law,
including workers' compensation insurance;  (ii) comprehensive general liability
insurance  with a combined  limit of not less than  $5,000,000  of coverage  for
bodily injury and property  damage under a standard or excess  policy,  together
with  additional  insurance  required to cover  claims,  losses and  liabilities
hereunder;  (iii) a fidelity  bond covering  Sprint,  its officers and employees
with a limit of not less than $5,000,000, underwritten by an insurer licensed to
do business in the state of Missouri; and (iv) automobile liability insurance in
the amount of not less than  $1,000,000.  Sprint's general  liability  insurance
shall include  coverage for claims  brought  against  Sprint as a result of work
performed  by its  subcontractors.  The policy  limits set forth in this Section
shall in no way be construed as a limitation on Sprint's liability hereunder.

                  (ii) Sprint shall  furnish to Bridge,  upon  written  request,
certificates of insurance or other appropriate documentation (including evidence
of renewal  of  insurance)  evidencing  the  general  liability  and  automobile
liability  insurance coverage  referenced above,  naming Bridge as an additional
insured.  Such  certificates  or other  documentation  shall include a provision
whereby  fifteen  (15) days' prior  written  notice  shall be provided to Bridge
prior to coverage  cancellation or other material alteration by either Sprint or
the applicable  insurer.  Such  cancellation  or material  alteration  shall not
relieve Sprint of its continuing  obligation to maintain  insurance  coverage in
accordance with this Subsection.

                  (iii)  In  lieu  of all or  part  of  the  insurance  coverage
specified  in  Subsection  (i),  Sprint  may  self-insure  with  respect  to any
insurance coverage, except where expressly prohibited by law.

         (e)      Representations and Warranties.

                  (i) Sprint  hereby  warrants  that the Products and  Services,
with the  exception  of the ISC  Cards,  will  operate  in  accordance  with the
Performance  Specifications  upon the date  installed and throughout the term of
this Agreement.  Sprint assumes no responsibility for the performance of the ISC
Cards because Bridge is contracting directly with ISC for special development of
the Cards.  Sprint  acknowledges  that, in the event of the  Interruption of any
Product or Service,  Bridge may suffer damages the amount of which cannot easily
be determined.

                           (A) In the event that Sprint does not provide overall
network  availability  as defined in  Attachment  E, Sprint shall grant Bridge a
credit (the "Credit  Allowance")  for the sites that cause  Sprint's  failure to
meet the overall network availability.

A separate  availability  calculation  will be derived  for those sites that are
contributory to Sprint's  failure to meet its network  availability  commitment.
Credits will be applied to those sites in accordance with the following table:

         For Site Types A, B1, B2, C1, C2, if the service availability is:

             Greater than
             or equal to            and less than             the credit is

No credit shall exceed 10% for any site.

                            (B) For any  Interruption  that the parties agree is
likely to last  beyond  ten (10) days,  Bridge  shall have the right in its sole
discretion to subscribe to an alternative Sprint service to replace the affected
Product or Service for the period of time that the  Products  and  Services  are
interrupted.  If Sprint cannot provide a suitable  alternative  service over its
own facilities,  Sprint shall obtain from other vendors or carriers the services
or  facilities  necessary  to provide  substitute  service to Bridge.  If Bridge
elects to obtain these alternative services through Sprint, Bridge shall pay the
lesser of the rates and  charges  for the  affected  Product  or  Service or the
charges incurred for the alternative  service (including usage charges, if any).
Sprint shall not charge Bridge to connect, commence or terminate any alternative
service obtained under this Subsection.

Bridge/Sprint Confidential               -12-                   January 30, 1995

<PAGE>

                            (C) Sprint shall not be liable for Credit Allowances
for an  Interruption  in  connection  with a Product or Service for which Bridge
obtains  alternative  service  under  Subsection  (B) after it begins using such
alternative service.

                  (ii) Sprint  hereby  represents  and  warrants  that the terms
hereof do not conflict in any respect  whatsoever with any Sprint tariff on file
with the Federal Communications  Commission or other regulatory body. If, during
the  term of this  Agreement,  Sprint  shall  file a  contract  specific  tariff
governing the Products and Services or any portion  thereof,  such tariff filing
shall be consistent in all respects with the terms of this Agreement, and Sprint
shall give Bridge ten (10) days'  advance  notice of making such a tariff filing
and of filing any subsequent modifications thereto.

                  (iii)  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.

17.      Limitations on Liability.

         (a) Each party's liability to the other during the service term for all
injuries  other than those listed in  Subsection  (c) below shall not exceed one
hundred thousand dollars ($100,000).

         (b)  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 regard to the Products and Services or other conduct under this Agreement.

         (c)  Nothing  contained  in this  Section  shall limit  either  party's
liability to the other for (i) willful or intentional misconduct; or (ii) injury
or death,  or damage to  tangible  real or  tangible  personal  property  or the
environment,  when proximately caused by Sprint's or Bridge's negligence or that
of their  respective  agents,  subcontractors  or employees.  Nor shall anything
contained in this Section limit Sprint's intellectual  property  indemnification
obligations under Section 21.

18.      Equipment and Software Not Provided by Sprint.

         (a) Sprint shall not be responsible for the installation,  operation or
maintenance  of equipment or software not  provided  under this  Agreement;  nor
shall Sprint be responsible for the  transmission or reception of information by
equipment  or software  not  provided  hereunder.  In the event that Bridge uses
equipment or software not provided  hereunder in a manner that impairs  Bridge's
use of the Products and  Services,  Bridge shall not be excused from payment for
such use.

Bridge/Sprint Confidential               -13-                   January 30, 1995

<PAGE>

Upon notice  from Sprint that  equipment  or software  not  provided  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.

         (b)  Notwithstanding  the  foregoing,  Sprint  shall,  at no additional
charge,  provide all  interface  specifications  for the  Products  and Services
reasonably  requested by Bridge.  Sprint shall,  upon the receipt of appropriate
specifications from Bridge, inform Bridge of the compatibility with the Products
and  Services  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
Products and  Services;  and the effects if any, of the Products and Services on
the operating characteristics and efficiency of any such equipment or software.

         (c) If any material  modification or reprovisioning of Sprint's network
(including  any  modification  of the  software  for which a license is provided
hereunder)  undertaken other than at Bridge's request (i) adversely  affects any
of the Products and Services,  (ii) causes Bridge to incur significant costs for
any Products and Services (a write-down of equipment or equipment-related assets
being a cost for purposes of this  Subsection),  (iii) prevents proper operation
of any Bridge equipment, or (iv) prevents any Products and Services from meeting
any  Performance  Specification,  Bridge shall have the right to  terminate  any
adversely  affected  Products and  Services  pursuant to Section 5. Sprint shall
provide   advance   notification   to  Bridge  of  any  such   modification   or
reprovisioning.

19.      Proprietary Rights; License.

         (a) Sprint hereby grants to Bridge a non-exclusive and non-transferable
license to use all  programming  and  software  necessary  for Bridge to use the
Products and  Services.  Such license is granted for the term of this  Agreement
and for the sole purpose of enabling Bridge to use the Products and Services.

         (b) All title and  property  rights  (including  intellectual  property
rights) to Products and Services (including associated programming and software)
are and shall  remain with Sprint.  Bridge  shall not attempt to examine,  copy,
alter,  "reverse  engineer,"  tamper with or otherwise  misuse such Products and
Services,  programming  and software.  Bridge accepts title to the Equipment and
risk of loss of Equipment FOB destination.

20.      Confidentiality.

         (a)  During  the term of this  Agreement  and for a period  of five (5)
years  from the date of its  expiration  or  termination  or the  expiration  or
termination of all extensions  thereto,  each party agrees to maintain in strict
confidence  all  Confidential  Information.  Neither party shall,  without prior
written consent,

Bridge/Sprint Confidential               -14-                   January 30, 1995

<PAGE>

use the other party's  Confidential  Information  for any purpose other than for
the performance of its duties and obligations  under this Agreement.  Each party
shall use, and 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.

         (b)  Notwithstanding  Subsection  (a),  either  party may  disclose the
Confidential Information of other party to: (i) its employees and the employees,
directors  and  officers  of its  affiliates  as  necessary  to  implement  this
Agreement;  (ii)  employees,  agents or  representatives  of the other party; or
(iii) 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  (iii) shall be made only upon the prior  written  approval of the
other party and subject to  appropriate  assurances  that the  recipient of such
information shall hold it in strict confidence.

         (c)  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) 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 same.

         (d) 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, in its sole discretion,
it determines to grant the requested  waiver,  it will do so in writing over the
signature of an employee authorized to grant such request.

         (e)   Bridge   and   Sprint   acknowledge   that  any   disclosure   or
misappropriation  of  Confidential  Information  in violation of this  Agreement
could cause irreparable harm, the amount of which may be extremely  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.

         (f) A party requested or ordered by a court order 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

Bridge/Sprint Confidential               -15-                   January 30, 1995

<PAGE>

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.

21.      Indemnification.

         (a) Sprint shall defend,  settle,  or otherwise manage its own cost and
expense any claim or action against  Bridge or any of its  directors,  officers,
employees  or  permissible  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  use of the Products and
Services.  Bridge shall notify  Sprint  promptly in writing of any such claim or
suit and shall  cooperate  with Sprint in a  reasonable  way to  facilitate  the
settlement  or defense  thereof.  Sprint  further  agrees to indemnify  and hold
Bridge  harmless  from and against  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
Subsection.

         (b) If, as a consequence  of a claim or action of the kind described in
Subsection  (a),  Sprint's or Bridge's  use of any Product or Service or related
documentation is enjoined,  Sprint shall, at its own option and expense, either:
(i)  procure  for Bridge the right to  continue  using the  affected  Product or
Service or  documentation;  (ii) modify such Product or Service or documentation
so that it is  non-infringing  (provided that such  modification does not affect
the  intended  use of the Product or Service or  documentation  as  contemplated
hereunder);  or (iii) upon written notice to Bridge, substitute for such Product
or  Service  or   documentation   a   comparable,   non-infringing   service  or
documentation.  If Sprint  cannot do (i)-(iii)  above,  Bridge may terminate any
affected  Product or Service  pursuant to Section 5, and Sprint  shall refund to
Bridge any prepaid charges therefor.

         (c) Sprint and Bridge  will be  indemnified  and saved  harmless by the
other  from and  against  all loss,  liability,  damage and  expense,  including
reasonable counsel fees, caused by:

                  (i)  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
network by Bridge; and

                  (ii) Claims for  infringement  of patents arising from the use
of equipment  and  software,  apparatus  and systems not  provided  hereunder in
connection with Products and Services.

22.      Assignment.

         Neither  party may assign this  Agreement or any rights or  obligations
hereunder, without the prior written consent of the other party, which the other
party  may  grant  or  withhold  in its  sole  discretion.  Notwithstanding  the
foregoing,  either  party may assign this  Agreement or any or all of its rights
and obligations hereunder,  to its parent, any of its affiliates or subsidiaries
upon notice to, but without the consent of, the other party.  No  assignment  of
this Agreement  shall relieve either party of any  obligations  thereunder.  Any
attempted assignment in violation of this Section shall be void.

23.      Force Majeure.

         (a) 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  Sprint's or  others'),  casualties,
accidents or other causes beyond the control of the party  claiming  excuse.  No
failure to perform  shall be excused under this  Subsection  unless such failure
and the  consequences  thereof  are beyond the  control and without the fault or
negligence of the party claiming excuse.  Each party shall, with the cooperation
of the other,  use  reasonable  efforts to mitigate the extent of any failure to
perform and the adverse consequences thereof.

         (b) If Sprint  cannot  promptly  provide a  suitable  temporary  Sprint
alternative  to a Product or Service  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 any or all affected
Products and Services for the shortest  commercially  available period likely to
cover the  reasonably  expected  duration of the  Interruption,  and may suspend
Sprint's  provision of such Products and Services for such period.  Sprint shall
not charge Bridge for any Products and Services thus suspended during the period
of  suspension.  Sprint shall resume  provision  of the  suspended  Products and
Services 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.

         (c) In the event that a force majeure condition shall continue for more
than sixty (60) days,  Bridge may cancel the affected Products and Services with
no further  liability to Sprint other than for Products and Services received by
it prior to the occurrence of the force majeure condition.

24.      Modifications.

         No  modification,  amendment,  or supplement to the Agreement or any of
its  provisions  shall be binding  upon the  parties  unless made in writing and
signed by an authorized  representative  of the party  against whom  enforcement
thereof is  sought.  A failure  or delay of either  party to enforce  any of the
provisions of this

Bridge/Sprint Confidential               -17-                   January 30, 1995

<PAGE>

Agreement,  to exercise  within the time specified (if any) any option  provided
herein,  or to require  performance  of any provision  hereof shall in no way be
construed to be a waiver of such option or provision.

25.      Notices.

         All notices or other  communications  required or permitted to be given
or delivered  under this Agreement shall be in writing and shall be sufficiently

given if delivered,  in the case of disputes  arising under this  Agreement,  by
registered  mail or overnight  express  mail service or, in all other cases,  by

publicity  release,  solicitation  or  promotional  material,  or  advertisement
without the prior written consent of the other. This prohibition includes use of
the other's name,  trademarks or logos or any other reference to the other party

                     DOMESTIC INSTALLATION, MAINTENANCE, AND
                               MANAGEMENT SERVICES

This document describes the installation,  maintenance,  and management services
provided by Sprint for Bridge's managed router network.

I.       INSTALLATION

Sprint  will  provide  installation  services  for all  routers,  Telebit  PN2DE
Netblazers,  and Telebit modems ordered from Sprint.  Sprint reserves the rights
to employ third party vendors for the actual on-site installation.  Installation
for fully managed routers consists of:

         1.       A physical or telephone  site survey may be required  prior to
                  installation.

         2.       Collection  of  necessary  configuration  information  using a
                  Sprint  provided  router   installation  form  (joint  process
                  between  Sprint and the customer).  Configuration  information
                  must be  completed  prior to the install and each site must be
                  certified  by Bridge as ready for  installation.  Physical and
                  electrical   requirements   must  be  met  for  each  site  in
                  accordance  with standard  requirements  provided by Wellfleet
                  and Telebit.

         3.       Sprint will provide installation services for the Bridge owned
                  Codex 3520 DSUs.  Bridge will be responsible for de-installing
                  these DSUs and shipping them to Bridge where a V.35 cable will
                  be  installed.  Bridge will then send the DSU and cable to the
                  Sprint Repair Depots (RDs).  Bridge agrees to have one month's
                  supply   (approximately   80)  DSUs  in  the  RDs  during  the
                  implementation period.

II.      MAINTENANCE PLANS

         A. WELLFLEET ROUTERS

analysis, and correction of troubles. This group is accountable to customers for
the end-to-end  management of network  services.  The Internet  Network  Service
Center (INSC) is the group that actually monitors customer router networks.  The
Enterprise Internet Engineering (EIE) group is responsible for the configuration
and design of a customers  network.  Sprint will  provide  Customer  with router
network management  services  including Single Point of Contact,  Trouble Ticket
Handling,  Maintenance  Coordination,  24 X 7 Proactive  Network  Monitoring and
Fault Management,  Out of Band Dial-in Network Management Access,  Configuration
Management, and Router Network Engineering.

         A.       SINGLE POINT OF CONTACT:

         24 hours per day, 7 days per week, 365 days a year,  Sprint's  Internet
         Network  Service  Center (INSC)  provides a single point of contact for
         troubles  (Routers and  Transport)  associated  with the managed router
         service. Trouble reports are received from the customer's help desk via
         a domestic toll-free number.

         B.       TROUBLE TICKET HANDLING:

         A trouble  ticket  number will be provided  to the  customer  Help Desk
         reporting  trouble.  For each  trouble  report,  Sprint  will  maintain
         information about the trouble,  the steps taken to resolve the trouble,
         and  the   final   disposition   of  the   trouble   report.   Customer
         representatives  will  be  kept  apprised  of  the  status  of  service
         restoration  actions.  A  trouble  ticket  will not be closed by Sprint
         until Bridge is satisfied that the problem has been corrected.

         C.       MAINTENANCE COORDINATION:

         The services of any third party vendors required to service portions of
         the managed router service will be coordinated by Sprint. The INSC will
         dispatch vendor  technicians to perform  on-site router  maintenance as
         necessary.  Any higher-level assistance will also be coordinated by the
         INSC.

         D.       OUT-OF-BAND DIAL-IN NETWORK MANAGEMENT ACCESS:

         Bridge is  required  to  provide a  standard  business  line for remote
         out-of-band  dial-in to each customer site. V.32 compatible modems will
         be attached to the business  line and an auxiliary  port on the router.
         Sprint's  INSC will then be able to dial in to customer  routers.  If a
         problem  occurs where the INSC can no longer access the router  in-band
         from the network  management  system,  a technician will dial in to the
         affected router's modem port. The technician will then be able to check
         the router and its ports for trouble.

         E.       NETWORK MONITORING AND FAULT MANAGEMENT:

         Sprint's  INSC will provide  network  monitoring  and fault  management
         services 24 hours per day, 7 days per week, and 365 days per year. This
         includes the detection, isolation, diagnosis, and correction of network
         troubles. The INSC operates a Simple Network Management Protocol (SNMP)
         based  management  system which provides  real-time,  graphics-oriented
         network management of routers and associated communications links. This
         management  system will be used for initial  screening  of all customer
         trouble reports.  It is Sprint's objective to respond within 15 minutes
         of all detectable network events.

         F.       CONFIGURATION MANAGEMENT AND ROUTER NETWORK ENGINEERING:

         As part of the provisioning process, Sprint may conduct site surveys of
         user  locations  to  develop  data  required  for  circuits  and router
         installation.  Pre-coordination  with  customer  technical  staff  will
         ascertain  information needed to properly configure the routers such as
         routing protocols,  applications,  traffic,  connectivity requirements,

         electronic form.  Sprint will monitor these statistics on a daily basis
         for trends and potential problems.
