                            CARRIER SERVICE AGREEMENT

This  Carrier  Service  Agreement  ("AGREEMENT")  is entered  into  between  the
provider of service, Frontier Communications of the West, Inc., f/k/a West Coast
Telecommunications,  Inc. on behalf of itself and its affiliates ("FRONTIER"), a
California  corporation located at 90 Castilian Drive,  Goleta, CA 93117 and IDX
International,  Inc.  ("IDX or  "PURCHASER"),  a Virginia  corporation  with its
principal place of business located at 12015 Lee Jackson Hwy, Fairfax,  VA 22033
(hereinafter, Frontier and IDX may be referred to in the aggregate as "PARTIES",
and each singularly as a "PARTY".)

                                     PURPOSE

The Parties are telecommunications carriers subject to the Communications Act of
1934, as amended, as well as the  Telecommunications Act of 1996. IDX desires to
purchase network  transport and other  telecommunication  services from Frontier
for IDX's resale to its business and residential customers. The Parties agree as
follows:

1.      SERVICES:

         (a)   Frontier shall, in accordance with this Agreement, provide to IDX
               those  services  IDX  subscribes  to  hereunder  as  defined  and
               identified   herein  and  on   exhibits,   schedules   and  other
               attachments  appended  hereto  and made a part of this  Agreement
               from time-to-time by the Parties (collectively, the "SCHEDULES").
               All  such  services   being  provided  under  the  Schedules  are
               collectively referred to as the "SERVICES".

         (b)   In the event IDX is not billing at least $25,000 in total monthly
               dollar usage for Services within six (6) months from the Start of
               the Service Date,  Frontier may at any time upon thirty (30) days
               written  notice  to  IDX,  terminate  this  Agreement  for  under
               utilization of the Services.

         (c)   IDX shall provide Frontier with a forecast  covering a good faith
               estimate  based on historical  information  (if available) of the
               monthly traffic volume and geographic distribution for an ordered
               Service.  The  estimate  will be for the 3 calendar  month period
               following  the desired  activation  date in a format  supplied or
               approved by Frontier. Frontier may request updated forecasts on a
               reasonable   basis.   Forecasts  of  not   constitute  a  binding
               commitment  on  the  part  of  IDX.   Provision  of  Services  is
               contingent on availability of Frontier facilities.

         (d)   Orders  for  Services  will  be  transmitted   and  processed  in
               accordance with the procedures  provided to IDX from time to time
               by Frontier.

2.      TERM OF THE AGREEMENT:

         (a)   INITIAL  TERM:  This  Agreement  is  effective  and the  Parties'
               obligations  commence  upon the  date of  execution  by  Frontier
               ("EFFECTIVE  DATE") and  continues  in effect for a period of one
               (1) year  ("INITIAL  TERM")  from either the day Service is first
               utilized by IDX (as  determined  by Frontier's  records).  Or the
               90th day after the Effective  Date,  whichever date occurs first,
               such date known as the "START OF SERVICE DATE".

         (b)   AUTOMATIC RENEWAL:  This Agreement renews automatically for a one
               year  period  at the  expiration  of  the  Initial  Term,  unless
               canceled in accordance  with the  termination  provisions of this
               Agreement   ("SUBSEQUENT  TERM").  Each  Subsequent  Term  renews
               automatically  for a one year period upon its expiration,  unless
               canceled in accordance  with the  termination  provisions of this
               Agreement.

                                                                   [Initials JG]
                                                                  [Initials BVF]

<PAGE>

         (c)   CANCELLATION:  Either Party may  terminate  this  Agreement  upon
               expiration  of a term upon written  notice given at least 30 days
               prior to expiration of the then current term.

3.       BILLING AND  PAYMENT:  IDX shall pay  Frontier  for the Services at the
         rates  and  charges  set  out in the  applicable  Schedules.  If IDX is
         required to pay an initial cash deposit or provide  other  assurance of
         payment,  then Frontier is not obligated to begin  accepting  orders or
         providing  'Service until the deposit or other  assurance of payment is
         received.

         (a)   IDX shall provide  security in the form of an irrevocable  letter
               of credit in the amount of $25,000  from a financial  institution
               and in a format  acceptable to Frontier,  and additionally in the
               form of a UCC-1 granting  Frontier a first  security  interest in
               IDX's existing and hereafter acquired accounts,  contract rights,
               chattel paper, account receivable (including funds deposited into
               lock box and similar accounts) and general  intangibles,  and all
               products and proceeds thereof, including without limitation, call
               detail  records,  customer  contracts,  records and lists and all
               causes of action for  recovery  or  collection  of the  foregoing
               (collectively,  the  "COLLATERAL")  to the extent such Collateral
               relates in any manner to Services  being  provide to IDX or IDX's
               customer's  by   Frontier.;   IDX  shall  execute  any  documents
               reasonably  required by  Frontier  to perfect the above  security
               interest.

         (b)   Frontier  shall  invoice IDX via  facsimile on or about the fifth
               Business  Day  after  the  close of each  Billing  Cycle  for the
               Services  and for any other sums due Frontier  ("INVOICE").  Each
               invoice details:  (i) the amount due Frontier,  or the credit due
               IDX,  after a  reconciliation  between the actual charges for the
               Services of the prior Billing Cycle and any required  pre-payment
               for the  prior  Billing  Cycle,  and  (ii)  any  other  sums  due
               Frontier.   Except  if   Frontier   has   agreed  to  a  lock-box
               arrangement, in addition to the amounts under (i) and (ii) above,
               the Invoice  will  provide for a  pre-payment  equal to 0% of the
               actual  charges  for the  Services  for the prior  Billing  Cycle
               (exclusive of any non-recurring  charges). If IDX has submitted a
               letter of credit that has an expiration date greater than 45 days
               after the Invoice date, or a cash deposit,  the pre-payment for a
               given month will be reduce by the amount of such security (but to
               not less than zero).

         (c)   Each  Invoice  shall be paid by IDX in  immediately  available US
               funds so that the  payment is  received by Frontier no later than
               thirty (30)  calendar days from the date of the Invoice (the "DUE
               DATE").  Frontier  agrees that (i) the  Invoice  date will be the
               same day the Invoice is faxed to IDX,  and (ii) the Invoice  will
               be faxed on a Business  Day. Any Invoice not paid by the Due Date
               shall bear late  payment fees at the rate of 1-1/2% per month (or
               such lower amount as maybe required by law) until paid.

         (d)   The IDX facsimile number and contact for purposes of this Section
               3. are 703-385-9134,  Attention: Divya Katya, Accounting Manager.
               IDX may change the  facsimile  number and  contact  upon  written
               notice to Frontier.

         (e)   If IDX is  delinquent  in payment of an Invoice and Frontier does
               not have  security  from IDX equal to IDX's prior  month's  usage
               charges,  IDX shall provide such additional  security as Frontier
               may reasonably request in writing.

         (f)   FRAUDULENT  USAGE.  Subject to the fraudulent usage provisions of
               the  Frontier   InterLink   Calling  Card  Services  Schedule  if
               applicable, Frontier is not responsible for any fraudulent use of
               Service.  IDX is  solely  responsible  for all  Services'  usage,
               fraudulent  or otherwise.  Claims of  fraudulent  usage shall not
               constitute a valid basis for dispute of an Invoice. Frontier will
               monitor End-User call activity for suspected fraudulent use using
               the same procedures  Frontier uses for its own customers  (except
               Frontier   will  contact  IDX  in  lieu  of  the  End-User   when
               investigating suspected fraudulent use).

                                                                   [Initials JG]
                                                                  [Initials BVF]

         (g)   IDX agrees to pay to Frontier any and all local exchange  carrier
               ("LEC")  assessed charges (other than access or other LEC charges
               otherwise  included  under  this  Agreement)  and  governmentally
               mandated  charges  levied  upon  Frontier as a result of Services
               provided to IDX, such as but not limited to:

               (i)   assessment  by  regulatory  agencies,   including  but  not
                     limited to, the Federal Communications Commission (FCC) and
                     state Public Utility/Service Commissions (PUC):

               (ii)  charges or costs incurred by Frontier for FCC/PUC  mandated
                     initiatives  under the  Telecommunications  Act of 1996, or
                     otherwise,  such  as  the  "access  reform"  and  "payphone
                     dial-around  compensation"  initiatives,  plus a reasonable
                     fee for  administration of those initiatives  applicable to
                     the Services provided to IDX; and

               (iii) applicable  charges set out in the  Schedule  of  Ancillary
                     Fees attached hereto as Exhibit B and made a part hereof as
                     the same may be modified from time to time by Frontier upon
                     written notice to IDX.

         (h)   Frontier  may revise the rates and  monthly  recurring  and other
               charges  in this  Agreement  and the  Schedules  at any time upon
               written  notice to IDX.  Unless  otherwise  stated in the notice,
               domestic   rates   are   effective   within   thirty   days   and
               international/offshore  rates are effective  within seven days of
               the date of the Frontier  written  notice.  If the effective rate
               for a Service is increased  pursuant to this paragraph,  then IDX
               may cancel the Service  subject to the rate increase upon written
               notice to Frontier  given  within 30 days after IDX's  receipt of
               the rate increase  notice.  Cancellation  of a Service under this
               paragraph  includes a pro-rata reduction in the Minimum Charge to
               adjust for the Service being canceled. If a rate increase affects
               a portion  of a Service  that is not  severable  from the  entire
               Service  IDX shall not be able to cancel  the  affected  portion,
               e.g.  domestic  outbound  switched service is not cancelable as a
               result of a rate  increase  in  directory  assistance  calls (D/A
               cannot be  separately  blocked);  further,  if the rate  increase
               affects  traffic to a  particular  LATA or country,  IDX may only
               cancel  Service  to the  particular  LATA/country  to the  extent
               severable by Frontier.

         (i)   IDX agrees that any make up to minimum charges, shortfall charges
               and  surcharges  for which it is liable under this  Agreement are
               based  on  agreed  upon  minimum  commitments  on  its  part  and
               corresponding  rate  concessions on Frontier's  part, and are not
               penalties or consequential or other damages under Section 7.(b).

4.       BILLING  DISPUTES.  The  Parties  agree that time is of the essence for
         payment  of  all  Invoices.   IDX  shall  provide  written  notice  and
         supporting documentation for any good-faith dispute it may have with an
         Invoice ("DISPUTE") within 60 Business Days after IDX's receipt. If IDX
         does not report a Dispute within the 60 Business Day period,  IDX shall
         have waived its dispute rights for that Invoice. IDX shall pay disputed
         amounts,  subject  to  resolution  of the  Dispute.  Frontier  will use
         reasonable  efforts to resolve timely  Disputes within 30 Business Days
         after its receipt of the Dispute  notice.  If a Dispute is not resolved
         within the 30 Business Day period to IDX's satisfaction,  then at IDX's
         request  the  Dispute  will be  referred  to an  executive  officer  of
         Frontier.  If the Dispute is not resolved within 15 Business Days after
         the  referral,  then either Party may commence an action in  accordance
         with  Section 16.,  provided  that the  prevailing  Part in such action
         shall be entitled to payment of its reasonable  attorney fees and costs
         by the other Party.

                                                                   [Initials JG]
                                                                  [Initials BVF]

5.      TERMINATION RIGHTS:

         (a)   REGULATORY  CHANGES:  If the  FCC,  a  state  PUC or a  court  of
               competent  jurisdiction issues a rule,  regulation,  law or order
               which has the effect of canceling,  changing,  or superseding any
               material  term  or  provision  of this  Agreement  (collectively,
               "REGULATORY  REQUIREMENT"),  then this Agreement  shall be deemed
               modified  in  such  a  way  as  the  Parties  mutually  agree  is
               consistent  with the form,  intent and purpose of this  Agreement
               and is  necessary  to comply  with such  Regulatory  Requirement.
               Should  the  Parties  not  be  able  to  agree  on  modifications
               necessary to comply with a Regulatory  Requirement within 30 days
               after the Regulatory Requirement is effective,  then upon written
               notice  either  Party may, to the extent  practicable,  terminate
               that  portion  of  this  Agreement  impacted  by  the  Regulatory
               Requirement.

         (b)   Either Party may terminate  this Agreement upon the other Party's
               insolvency,  dissolution  or  cessation  of business  operations.
               Frontier may, upon written  notice,  immediately  terminate  this
               Agreement for IDX's failure to pay any delinquent  invoice, or to
               maintain  any other  assurance  of payment  that may be  required
               hereunder.

         (c)   In the event of a breach of any  material  term or  condition  of
               this  Agreement  by a Party (other than a failure to pay which is
               covered  under (b)  above),  the other Party may  terminate  this
               Agreement upon 30 days written notice, unless the breaching Party
               cures the breach  during the 30 day period.  A breach that cannot
               be reasonably  cured within a 30 day period may be addressed by a
               written waiver of this paragraph signed by the Parties.

         (d)   Upon any material breach by IDX not cured after expiration of all
               applicable  notice  and cure  periods,  Frontier  may at its sole
               option do any or all of the following:

               (i)   cease  accepting  or  processing  orders  for  Service  and
                     suspend Service;

               (ii)  cease all electronically and manually generated information
                     and reports (including any DCR not paid for by IDX);

         (a)   Each Party  agrees that all  information  furnished  to it by the
               other  Party,  or to which it has access  under  this  Agreement,
               shall be deemed the confidential  and proprietary  information or
               trade   secrets   (collectively   referred  to  as   "PROPRIETARY
               INFORMATION")  of the Disclosing  Party and shall remain the sole
               and  exclusive  property  of  the  Disclosing  Party  (the  Party
               furnishing  the  Proprietary   Information  referred  to  as  the
               "DISCLOSING  PARTY"  and  the  other  Party  referred  to as  the
               "RECEIVING  PARTY").  Each  Party  shall  treat  the  Proprietary
               information  and the contents of this Agreement in a confidential
               manner and, except to the extend necessary in connection with the
               performance  of its  obligations  under this  Agreement,  neither
               Party may  directly  or  indirectly  disclose  the same to anyone
               other than its employees on a need to know basis and who agree to
               be  bound by the  terms  of this  Section,  without  the  written
               consent of the Disclosing Party.

         (b)   The  confidentiality  of obligations of this Section do not apply
               to any  portion of the  Proprietary  Information  which is (i) or
               becomes public knowledge through no fault of the Receiving Party;
               (ii)  in the  lawful  possession  of  Receiving  Party  prior  to
               disclosure  to it by the  Disclosing  Party (as  confirmed by the
               receiving  Party's  records);  (iii)  disclosed to the  receiving
               Party without  restriction  on disclosure by a person who has the
               lawful  right to  disclose  the  information;  or (iv)  disclosed
               pursuant  to the  lawful  requirements  or  formal  request  of a
               governmental  agency.  If the  Receiving  Party is  requested  or
               legally compelled by a governmental agency to disclose any of the
               Proprietary  information of the Disclosing  Party,  the Receiving
               Party  agrees  that it will  provide  the  Disclosing  Party with
               prompt  written  notice of such  requests so that the  Disclosing
               Party  has the  opportunity  to pursue  its  legal and  equitable
               remedies regarding potential disclosure.

         (c)   Each Party  acknowledges  that its breach or threatened breach of
               this  Section may cause the  Disclosing  Party  irreparable  harm
               which would not be adequately  compensated  by monetary  damages.
               Accordingly,  in the  event  of any  such  breach  or  threatened
               breach,   the  receiving  Party  agrees  that  equitable  relief,
               including  temporary  or permanent  injunctions,  is an available
               remedy in addition to any legal  remedies to which the Disclosing
               Party may be entitled.

         (d)   Neither Party may use the name, logo, trade name,  service marks,
               trade marks,  or printed  materials  of the other  Party,  in any
               promotional or advertising material,  statement,  document, press
               release or  broadcast  without the prior  written  consent of the
               other  Party,  which  consent  may be granted or  withheld at the
               Party's sole discretion.

                              CALL DETAIL RECORDS

1.      If IDX requires call detail records for usage of the Services ("CDR") it
        has the  option of (i)  receiving  CDR on a monthly  basis via  magnetic
        tape,  and/or (ii) having  access on a daily basis via  electronic  data
        exchange.

2.      If IDX elects  option  1.(i),  then on or about the fifth  Business  Day
        following  the end of a Billing  Cycle,  Frontier  will  deposit with an
        overnight  delivery service for delivery to IDX a CDR Tape in the format
        established  by Frontier.  CDR Tapes rate the Services at Frontier rates
        in effect at the time the Services were provided and must be re-rated by
        IDX at its tariffed rates.

3.      If IDX elects option  1.(ii),  then Frontier will make CDR available for
        IDX's access Monday through Saturday,  excluding  nationally  recognized
        holidays,  for the prior period's  traffic.  IDX's access to CDR will be
        via electronic data exchange ("ELECTRONIC EXCHANGE") to either (i) IDX's
        designated  mainframe  computer via the IBM Information  Network ("IIN")
        via Network Data Mover ("NDM"),  o (ii) dedicated  personal computer via
        Procomm+ software.  IDX is liable for all transmission  charges together
        with the cost of Frontier  compatible hardware and software necessary at
        its location for use of Electronic  Exchange.  Frontier will archive CDR
        for 8 Business Days.

4.      IDX may cancel an option at any time on 30 days written notice.  IDX may
        change  an  existing  option  or  select a new  option  at any time upon
        written notice and payment to Frontier of any then current set up charge
        for such option.  Changes or new  selections are effective in the second
        Billing Cycle  following  receipt of the request and any required set up
        charge.

                         DEDICATED TERMINATION SCHEDULE

Unless  otherwise  stated,  domestic  calls are measured in 6 second  increments
after a 6 second minimum and international  calls in 6 second increments after a
30 second minimum.

Dedicated Termination Service:

1.      For domestic and international  traffic (including  Directory Assistance
        Transport)  originating from IDX's switch,  IDX shall pay the applicable
        rates set out in the attached pricing schedules.

2.      Each DS-1 circuit  connecting IDX to one of the Frontier POPs set out in
        the attached  Network  Interconnections  Schedule has a monthly  minimum
        usage  requirement of 100,000 minutes.  Frontier may add or delete a POP
        at any time upon written notice. If a DS-1 circuit experiences a minimum
        shortfall over two consecutive Billing Cycles,  Frontier may provide IDX
        with written notice of such fact and of Frontier's  intent to disconnect
        the under-minimum  circuit if the minimum is not attained by the Billing
        Cycle  commencing  after  the date the  notice  is  received.  IDX shall
        reimburse  Frontier for any termination fees or charges paid by Frontier
        to the circuit provider for early disconnection of such circuit.

3.      IDX shall be responsible,  at its sole expense, for all ordering of, and
        charges for,  dedicated  facilities  and equipment  required to maintain
        access,  interconnection  and interface  with  Frontier's  equipment and
        network.

4.      If at any given  month more than 15% of IDX's total  domestic  dedicated
        carrier  traffic  does not  terminate to a RBOC/GTE  franchised  region,
        Frontier  may apply a $0.04 per minute  surcharge to all of such traffic
        in excess of the 15%.

                                                                   [Initials JG]

                           FRONTIER ACCESS DIRECT[TM]
                     DEDICATED CARRIER TERMINATION SCHEDULE

Unless otherwise stated in a pricing schedule,  domestic calls are billed in six
second  increments and  international  calls in six second increments after a 30
second minimum (Mexico calls are billed in one minute increments).

1.       For domestic and international  traffic  originating from IDX's switch,
         IDX shall pay the  applicable  rates  set out in the  attached  pricing
         schedules.

2.       Each DS-1 circuit  interconnecting  IDX to one of the Frontier POPs set
         out in the  attached  Network  Interconnections  Schedule has a monthly
         minimum  usage  requirement  of 100,000  minutes.  Frontier  may add or
         delete a POP at any time upon written notice. If a circuit  experiences
         a minimum shortfall over two consecutive  Billing Cycles,  Frontier may
         provide IDX with written  notice of such fact and of Frontier's  intent
         to disconnect the under-minimum  circuit if the minimum is not attained
         by the Billing Cycle  commencing after the date the notice is received.
         IDX shall reimburse Frontier for any termination fees or charge paid by
         Frontier  to the  circuit  provider  for  early  disconnection  of such
         circuit.

3.       Unless  otherwise   agreed  by  Frontier  in  writing,   IDX  shall  be
         responsible, at its sole expense, for all ordering of, and charges for,
         dedicated   facilities  and  equipment  required  to  maintain  access,
         interconnection and interface with Frontier's equipment and network.

                      TOLL-FREE CARRIER TRANSPORT SCHEDULE

Billing increments for domestic and offshore calls will be six second increments
(calls  from Canada  will be billed in six second  increments  after a 30 second
minimum.

1.       In order to protect the integrity of its network  Frontier may, without
         liability,  temporarily block any Toll-Free Number having usage surges.
         Frontier agrees to use reasonable  efforts to promptly notify IDX after
         blockage has occurred.

2.       At IDX's  written  request  and to the extent  available  to  Frontier,
         Toll-Free  Directory  Assistance  is available  for Frontier  Toll-Free
         Numbers  only at the  charges  identified  below.  Due to the fact that
         Toll-Free Directory  Assistance is provided through an arrangement with
         a third  party,  the  provision of Toll-Free  Directory  Assistance  by
         Frontier is subject to the policies  and  procedures  promulgated  from
         time to time by such third  party.  IDX  understands  that any Frontier
         Toll-Free  number  listed with  Toll-Free  Directory  Assistance is not
         published in any written directory,  but is only available on a call-in
         basis.

3.       The transfer of Toll-Free  Numbers to another carrier is subject to the
         Guidelines  and the Frontier  policies  and  procedures  for  Toll-Free
         number/traffic  transfers  in  effect  at the  time  of  the  requested
         transfer.

4.       IDX  acknowledges  and  agrees  that  call  records  detail  (CDR)  for
         Toll-Free  Carrier  Transport it receives  from  Frontier may not match
         billable  CDR's from IDX's  switch as Frontier  bills IDX for all calls
         completed  to  their  switch  at  Time  point  7 minus  Time  point  1,
         (regardless of whether the call is completed to the called party).
