     In consideration of good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

1.  Switched Services; Other Documents; Start of Service.

     (A) Services.  MCI WorldCom agrees to provide and Customer agrees to
     accept and pay for switched telecommunications services and other
     associated services (collectively the "Switched Services") as further
     described in the "Attachments" attached hereto and incorporated herein by
     reference, which describe the particular services, rates, specific terms
     and other information necessary or appropriate for MCI WorldCom to
     provide the Switched Services to Customer.  The Switched Services
     provided by MCI WorldCom are subject to (i) the terms and conditions
     contained in this TSA and the Program Enrollment Terms (the "PET") which
     is attached hereto and incorporated herein by reference, (ii) the rates
     and discounts and other applicable terms set forth in Attachment(s)
     attached hereto from time to time and incorporated herein by reference,
     and (iii) each Service Request (described below) which is accepted
     hereunder.  The PET, as subscribed to by the parties, shall set forth the
     Effective Date, the Service Term, Customer's minimum monthly commitment,
     if any, and other information necessary to provide the Switched Services
     under this TSA.  In the event of a conflict between the terms of this
     TSA, the PET, the Attachments and the Service Request(s), the following
     order of precedence will prevail: (1) the PET, (2) the Attachments, (3)
     this TSA, and (4) Service Request(s).  This TSA, the PET, and the
     applicable Attachments are sometimes collectively referred to as the
     "Agreement".

     (B) Service Requests.  Customer's requests to initiate or cancel Switched
     Services shall be described in an appropriate MCI WorldCom
     Request("Service Request").  A Service Request may consist of machine
     readable tapes, facsimiles or other means approved by MCI WorldCom.
     Further, Service Requests shall specify all reasonable information, as
     determined by MCI WorldCom, necessary or appropriate for MCI WorldCom to
     provide the Switched Service(s) in question, which shall include without
     limitation, the type, quantity and end point(s) (when necessary) of
     circuits comprising a Service Interconnection as described in the
     applicable Service Schedules, or automatic number identification ("NI")
     information relevant to the Switched Service(s), the "Requested Service
     Date", and charges, if any, relevant to the Switched Services described
     in the Service Request.

     (C) Start of Service.  MCI WorldCom's obligation to provide and
     Customer's obligation to accept and pay for non-usage sensitive charges

<PAGE>

     for Switched Services shall be binding to the extent provided for in this
     Agreement upon the submission of an acceptable Service Request to MCI
     WorldCom by Customer.  Customer's obligation to pay for usage sensitive
     charges for Switched Services shall commence with respect to any Switched
     Service as of the date the Switched Service in question is made available
     to and used by Customer ("Start of Service"), but in no event later than
     "Requested Service Date" if such Switched Service is available for
    Customer's use as of such Requested Service Date.  Start of Service for
    particular Services shall be further described in the Attachment(s)
    relevant to the Switched Services in question.

2.  Cancellation.

     (A) Cancellation Charge.  At any time after the Effective Date, Customer
     may cancel this Agreement if Customer provides written notification
     thereof to MCI WorldCom not less than thirty (30 days prior to the
     effective date of cancellation.  In such case (or in the event MCI
     WorldCom terminates this Agreement as provided in Section 7), Customer
     shall pay to MCI WorldCom all charges for Services provided through the
     effective date of such cancellation plus a cancellation charge (the
     "Cancellation Charge") equal to one hundred percent (100%) of the
     Customer's commitment(s), if any, (as described in the PET) that would
     have become due for the unexpired portion of the Service Term.

     (B) Liquidated Damages.  It is agreed that MCI WorldCom's damages in the
     event Customer cancels this Agreement shall be difficult or impossible to
     ascertain.  The provision for a Cancellation Charge in Subsection 2(A)
     above is intended, therefore, to establish liquidated damages in the
     event of a cancellation and is not intended as a penalty.

     (C) Cancellation Without Charge.  Notwithstanding anything to the
     contrary contained in Subsection 2(A) above, Customer may cancel this
     Agreement, as provided below, without incurring any cancellation charge
     (other than payment for Services provided by MCI WorldCom up through the
     effective date of cancellation) if (i) MCI WorldCom fails to provide a
     network as warranted in Section 8 below; (ii) MCI WorldCom fails to
     deliver call detail records promptly based on the frequency selected by
     Customer (i.e., monthly, weekly or daily); or (iii) MCI WorldCom fails to
     submit ANI(s) relevant to Customer's Service Requests to the applicable
     local exchange companies ("LECs"0 within the time period described in
     applicable Attachment(s).  Provided, however, Customer must give MCI
     WorldCom written notice of any such default and an opportunity to cure
     such default within five (5) days of the notice.  In the event MCI
     WorldCom fails to cure any such default within five-day period on more
     than three (3) occasions within any six (6) month period, customer may
     cancel this Agreement without incurring any cancellation charge.

3.  Customer's End Users.

     (A) End Users.  Customer will obtain, and upon MCI WorldCom's request
     provide MCI WorldCom (within two (2) business days of the date of the
     request), a written Letter of Agency ("LOA") acceptable to MCI WorldCom
     (or with any other means if approved by the Federal Communications
     Commission ("FCC"), the applicable public utility commission ("PUC") and
     the applicable LEC), for each ANI indicating the consent of such end user
     of Customer ("End User") to be served by Customer and transferred (by way

     the End User has consented to the transfer being performed by Customer or
     Customer's designee.  When applicable, Customer will be responsible for
     notifying its End Users, in writing (or by

     applicable LEC) that (i) a transfer charge will be reflected on their LEC
     bill for effecting a change in their PIC, (ii) the entity name under
     which their interstate, intrastate, local and/or operator services will
     be billed (if different from Customer), and (iii) the "primary" telephone
     number(s) to be used for maintenance and questions concerning their
     telecommunications services and/or billing.  Customer agrees to send MCI
     WorldCom a copy of the documentation Customer uses to satisfy the above
     requirements for Customer's confirming orders and/or for notifying End
     Users regarding the transfer charge at any time in order to conform with
     applicable FCC and state regulations, including without limitation, the
     regulations established by the FCC with respect to verification of orders

     C.F.R., Part 64, Subpart K, Section 64.1100 or any successor regulation(s).

     (B) Transfer Charges/Disputed Transfers.  Customer agrees that it is
     responsible for (i) all charges incurred by MCI WorldCom to change the
     PIC of End Users to the MCI WorldCom network, (ii) all charges incurred
     by MCI WorldCom to change End Users back to their previous PIC arising
     from disputed transfers to the MCI WorldCom network plus, at MCI
     WorldCom's option, an administrative charge equal to twenty percent(20%)
     of such charges, and (iii)  any other damages or costs suffered by or
     awards against MCI WorlCom resulting from disputed transfers.

     (C) Excluded ANIs.  Customer agrees to provide all ANIs to be carried on
     the MCI WorldCom network prior to the provisioning of such ANIs with the
     LECs.  MCI WorldCom has the right to reject any ANI supplied by Customer
     for any of the following reasons: (i) MCI WorldCom is not authorized to
     provide or does not proved long distance services in the particular
     jurisdiction in which the ANI is located, (ii) a particular ANI submitted
     by Customer is not in proper form, (iii) Customer is not certified to
     provide ling distance services in the jurisdiction in which the ANI is
     located, (iv) Customer is in material default of this Agreement, (v)
     Customer fails to cooperate with MCI WorldCom in implementing reasonable
     verification processes determined by MCI WorldCom to be necessary or
     appropriate in the conduct of business, (vi) such ANI is rejected by a
     LEC (e.g., "PIC freezes"),j or (vii) any other circumstance reasonably
     determined by MCI WorldCom which could adversely affect MCI WorldCom's
     performance under this Agreement or MCI WorldCom's general ability to
     transfer its other customers or other end users to the MCI Worldcom
     network, including without limitation, MCI WorldCom's ability to
     electronically effect PIC changes with the LECs.  In the event MCI
     WorldCom rejects an ANI, MCI WorldCom will notify Customer of its
     decision specifically describing the rejected ANI and the reason(s) for
     rejecting that ANI, and will not incur any further liability under this
     Agreement with regard to that ANI.  Further, any ANI previously requested
     by Customer for Switched Services may be deactivated by MCI WorldCom if
     no Switched Services billings relevant thereto are generated in any three
     (3) consecutive calendar month/billing periods.  MCI WorldCom will be
     under no obligation to accept ANIs submitted by Customer within the last
     full calendar month period preceding the scheduled expiration of the
     Service Term.

     (D) Records.  Customer will maintain documents and records ("Records")
     supporting Customer's re-sale of Switched Services, including, but not
     limited to, appropriate and valid documentation of each subscribing End
     User's authorization to Customer to act as the End User's PIC for a
     period of not less than twelve (12) months or such longer period as may
     be required by applicable law, rule or regulation.  Customer shall

     Switched Services to be provided to Customer.

     (E) Customer Service.  Customer will be solely responsible for billing
     its End Users and providing such End Users with customer service.

     Switched Services, including without limitation, excess noise, echo, or
     loss of service.

4.  Customer's Responsibilities.

     (A) Expedite Charges.  In the event Customer requests expedited services
     and/or changes to Service Requests and MCI WorlCom agrees to such
     request, MCI WorldCom will pass through the charges assessed by any
     supplying parteies( e.g., local access providers) for such expedited
     charges and/or changes to Service Requests involved at the same rate to
     Customer.  MCI WorldCom may further condition its performance of such
     request upon Customer's payment of such additional charges to MCI
     worldCom.

     (B) Fraudulent Calls.  Customer shall indemnify and hold MCI WorldCom
     harmless from any and all costs, expenses, damages, claims or actions
     arising from fraudulent calls of any nature which may comprise a portion
     of the Switched Services to the extent that the party claiming the
     call(s) in question to be fraudulent is (or had been at the time of the
     call) an End User of such Switched Services through Customer or an end
     user of the Switched Services through Customer's distribution channels.
     Customer shall not be excused from paying MCI WorldCom for Switched
     Services provided to Customer or any portion thereof on the basis that
     fraudulent calls comprised a corresponding portion of the Switched
     Services.  In the event MCI WorldCom discovers fraudulent calls being
     made (or reasonable believes fraudulent calls from taking place,
     including without limitation, denying Switched Services to particular
     ANIs or terminating Switched Services to or from specific locations.

     MCI WorldCom to take any action with respect to fraudulent calls.

5.  Charges and Payment Terms.

     (A) Payment.  MCI WorldCom billings for Switched Services hereunder are
     made on a monthly basis (or such other basis as may be mutually agreed to
     by the parties) following Start of Service.  Subject to Subsection 5(C)
     below, Switched Services shall be billed at the rates set forth in the
     applicable Attachment(s).  Customer will pay all undisputed charges
     relative to each MCI WorldCom invoice for Switched Services within thirty
     (30) days of the invoice date set forth on each MCI WorldCom invoice to
     Customer ("Due Date").  If payment is not received by MCI WorldCom on or
     before the Due Date, Customer shall also pay a late fee in the amount of
     the lesser of one and one-half percent (1 1/2 %) of the unpaid balance of
     the charges for Switched Services rendered per month or partial month
     that such payment is late, or the maximum lawful rate under applicable
     state law.

     (B) Taxes.  Customer acknowledges and understands that MCI WorldCom
     computes all charges herein exclusive of any applicable federal, state or

<PAGE>

     local use, excise, gross receipts, sales and privilege taxes, duties,
     fees or similar liabilities (other than general income or property
     taxes), whether charged to or against MCI WorldCom or Customer because of
     the Switched Services furnished to Customer ("Additional Charges").
     Customer shall pay such Additional Charges in addition to all other
     charges provided for herein.  Customer will not be liable for certain
     Additional Charges if Customer provides MCI WorldCom with an appropriate
     exemption certificate.

     (C) Modification of Charges.  MCI WorldCom reserves the right to
     eliminate particular Switched Services and/or modify charges for
     particular Switched Services (which charge modifications shall not exceed
     then0current generally available MCI WorldCom charges for comparable
     services), upon not less than sixty (60) days prior notice to customer,
     which notice will state the effective date for the charge modification.
     In the event MCI WorldCom notifies Customer of the elimination of a
     particular Switched Service and/or an increase in the charges, Customer
     may terminate this Agreement without incurring a cancellation charge
     (other than payment for Services provided by MCI WorldCom up through the
     effective date of cancellation) only with respect to the Switched
     Service(s), Customer must notify MCI WorldCom, in writing, at least
     thirty (30 days prior to the effective date of the increase in charges.
     In the event Customer cancels its subscription to a particular Switched
     Service as described in this Subsection 5(C), MCI WorldCom and Customer
     agree to negotiate in good faith concerning Customer's minimum monthly
     commitment, if any, described in the PET.

     (D) Billing Disputes.  Notwithstanding the foregoing, amounts reasonably
     disputed by Customer (along with late fees attributed to such amounts)
     shall apply but shall not be due and payable for a period of sixty (60
     days following the Due Date therefor, provided Customer: (i) pays all
     undisputed charges on or before the Due Date, (ii) presents a written
     statement and supporting documentation of any billing discrepancies to
     MCI WorldCom in reasonable detail on or before the Due Date of the
     invoice in question, and (iii) negotiates in good faith with MCI WorldCom
     for the purpose of resolving such dispute within said sixty (60 day
     period.  In the event such dispute is mutually agreed upon and resolved
     in favor of MCI WorldCom, Customer agrees to pay MCI WorldCom the
     disputed amounts together with any applicable late fees within ten (10)
     days of the resolution (the "Alternate Due Date").  In the event such
     dispute is mutually agreed upon and resolved in favor of Customer,
     Customer will receive a credit for the dispute within such sixty (60) day
     period (unless MCI WorldCom has agreed in writing to extend such period)
     all disputed amounts together with late fees shall become due and
     payable, and this provision shall not be construed to prevent Customer
     from pursuing any available legal remedies.  MCI WorldCom shall not be
     obligated to consider any Customer notice of billing discrepancies which
     are received by MCI WorldCom more than sixty (60) days following the Due
     Date of the Invoice in question.

6.  Credit; Creditworhiness:

     (A) Credit.  Customer's execution of this Agreement signifies customer's
     acceptance of MCI WorldCom's initial and continuing credit approval
     procedures and policies.  MCI WorldCom reserves the right to withhold
     initiation or full implementation of any or all Switched Services under
     this Agreement pending MCI WorldCom's initial satisfactory credit review
     and approval thereof which may be conditioned upon terms specified by MCI
     WorldCom, including, but not limited to, security for payments due
     hereunder in the form of a cash deposit or other means.  MCI WorldCom
     reserves the right to modify its requirements,

     (i) disconnect all or any portion the Switched Services being provided
     hereunder and/or terminate this Agreement; (ii) withhold billing
     information from Customer; and/or (iii) contact the End Users (for Whom
     calls are originated and terminated solely over facilities comprising the
     MCI WorldCom network) directly and bill such End Users directly until
     such time as MCI WorldCom has been paid in full for the amount owed by
     Customer.  If Customer fails to make payment by the date stated in the
     Suspension Notice and MCI WorldCom, after giving Customer five (5) days
     prior written notice, terminates this Agreement as provided in this
     Section 7, such termination shall not relieve Customer for payment of the

     MCI WorldCom's involvement in said proceeding is based solely on MCI
     WorldCom's provision of Switched Services to Customer.

Services with end points within a single state or Switched Services which
originate/terminate at points both of which are situated within a single
state.  In those states where MCI WorldCom is authorized to provide intrastate

other materials shall be deemed not approved. Customer agrees to change or
correct, at Customer's expense, any such material or activity which MCI
WorldCom, in its sole judgment, determines to be inaccurate, misleading or
otherwise objectionable for any reason. Customer is explicitly authorized to
only use the following statements in its sales literature or if in response to
an inquiry by Customer's End User. (i) "Customer utilizes the MCI WorldCom
network", (ii) "Customer utilizes MCI WorldCom's facilities", (iii) "MCI
WorldCom provides only the network facilities", and (iv) "MCI WorldCom is our
network services provider". Except as specifically provided in this Section
13, the parties further agree that any press release, advertisement or
publication generated by a party regarding this Agreement, the Services

other party or the other party's parent or affiliated company(ies), will be
submitted to the non-publishing party for its written approval prior to

                     MCI WORLDCOM NETWORK SERVICES, INC.

                               AMENDMENT NO. 1

     This Amendment No. 1 is made this 10th day of November , 1999, by and
between Cybertel Communications, Inc. ("Customer") and MCI WORLDCOM Network
Services, Inc. (successor-in-interest to WorldCom Network Services, Inc.)
("MCI WorldCom"), to those certain Program Enrollment Terms (the "PET"), to
the applicable Attachment(s) (the "Attachment(s)"), and to that certain
Switched Services Telecommunications Services Agreement and more particularly
described as TSA#CCC-991006  (the "TSA"), made by and between Customer and MCI
WorldCom dated October  10 1999. In the event of any conflict between the
terms of the TSA, the Attachment(s), or the PET and the terms of this
Amendment No. 1, the terms of this Amendment No. 1 shall control. The TSA
along with the PET, the Attachment(s) attached to the TSA, and this Amendment
No. 1 shall collectively be referred to as the "Agreement".

     The parties agree for good and valuable consideration, intending legally
to be bound, as follows:

A.   SERVICE TERM. The parties agree to substitute Section 1 of the PET to
     read in its entirety as follows:

     1.   SERVICE  TERM: This Agreement shall commence as of October 6, 1999
          (the "Effective Date"), and shall continue through and include
          August 1, 2003 (the "Service Term"). Upon expiration of the Service
          Term, the Switched Services in question will continue to be provided
          pursuant to the same terms and conditions as are then in effect
          (including without limitation, the applicable rates, discounts and
          commitments, if any), subject to termination by either party upon
          thirty (30)days prior written notice to the other party.

B.   CUSTOMER'S MINIMUM REVENUE COMMITMENT. Commencing with the August, 2000
     billing period (i.e., September, 2000 invoice) and continuing through the
     end of the Service Term (including any extensions thereto) (the
     "Commitment Period"), Customer agrees to maintain, on a take-or-pay
     basis, Monthly Revenue (as defined in Section 2 of the PET) of at least
     $1 ,000,000 ("Customer's Minimum Revenue Commitment").

C.   DEFICIENCY CHARGE: In the event Customer does not maintain Customer's
     Minimum Revenue Commitment in any month during the Commitment Period
     (regardless of whether Customer has commenced using any or all of the
     Switched Services described herein), then for those month(s) only,
     Customer will pay MCI WorldCom, in addition to charges due for Switched
     Services provided to Customer, the difference between Customer's Minimum
     Revenue Commitment and Customer's actual Monthly Revenue (as described in
     Section 2 of the PET) (the "Deficiency Charge"). The Deficiency Charge
     will be due at the same time payment is due for Switched

<PAGE>

     Services provided to Customer for the billing period in which the
     Deficiency Charge arises, or immediately in an amount equal to Customer's
     Minimum Revenue Commitment for the unexpired portion of the Service Term,
     if MCI WorldCom terminates this Agreement based on Customer's default or
     if Customer terminates this Agreement pursuant to Section 2(A) of the
     TSA. It is agreed that MCI WorldCom's damages in the event Customer fails
     to maintain Customer's Minimum Revenue Commitment shall be difficult or
     impossible to ascertain. The provision for a Deficiency Charge in this
     Paragraph C is intended, therefore, to establish liquidated damages in
     the event Customer fails to maintain Customer's Minimum Revenue
     Commitment and is not intended as a penalty.

D.  SPECIAL RATES:

     (A) Notwithstanding anything to the contrary contained in the applicable
     Attachments attached to the TSA, commencing as of November  1, 1999 and
     continuing through the end of the Service Term, with respect to CLASSIC

     WorldCom reserves the right to modify the Special Rates described in

     then-current generally available MCI WorldCom charges for comparable
     services), upon not less than fifteen (15) calendar days' prior notice to
     Customer (facsimile being acceptable), which notice will state the
     effective date for the charge modification.

     Attachment for CLASSIC 2000 SWITCHLESS/END USER DEDICATED Services, and

     herein, the terms and conditions of the Agreement will remain in full
     force and effect throughout the Service Term and any extensions thereof.

on the date first written above.

         (4) By either party, upon fifteen (15) days' prior written notice,

                                  ARTICLE 3
                                PAYMENT TERMS

3.1 Payment and Invoices.  Customer shall pay for Carrier Service weekly in
arrears.  Carrier Service shall be invoiced no later than two (2) calendar
days after the beginning of the week following the week for which Services
were provided, which invoice shall be paid via bank wire no later than two (2)
calendar days of the date of such invoice (the "Due Date").  All payment under
this Agreement shall be made in U.S. dollars.  Each calendar months Customer
shall be invoiced for the entire month indicating weekly payments and the
balance due for the final partial week (if applicable).  The month-end invoice
shall be paid in the same manner as each weekly interim invoice.

3.2 Taxes.  All Service under this Agreement are provided exclusive of any
applicable federal, local or foreign sales, use, excise, privilege, gross
receipts and other similar taxes, duties and charges imposed by any
governmental authority.  Such taxes, duties and charges shall be separately
stated on the monthly invoice and shall be paid directly by Customer unless
required to be collected by FRC, in which case such taxes, duties and charges
shall be paid to FRC to the appropriate authority upon receipt of payment from
Customer.  Any amounts not paid when the invoice is due shall be treated as a
late payment for purposes of Sections 2.2(b) and 3.4.  If Customer claims any
exemption from otherwise applicable taxes, duties or charges it shall provide
FRC with a valid tax exemption certification or other evidence reasonably
satisfactory to FRC that Customer is not subject to such taxes, duties or
charges.

<PAGE>

3.3 Disputed Charges.  If Customer, in good faith, disputes in writing the
amount or appropriateness of a charge included in an invoice from FRC,
Customer shall notify FRC of the disputed charge and provide documentation
reasonable requested by FRC to resolve the disputed charge.  Such notification
shall not relieve Customer of the obligation to make all payments by the due
date, including the amounts disputed by the Due Date.  Customer and FRC shall
exercise reasonable, good faith efforts to resolve the disputed charges.
Failure to contest a charge within forty-five (45) days of the date of the
invoice shall create an irrebuttable presumption of the correctness of the
charge.  If FRC and the Customer fail to resolve the disputed charge with
ninety (90) days from the date of the invoice, the parties are then free to
exercise their rights hereunder to seek remedy in a court of law and such
charges shall be considered due from the original Due Date and shall be
subject to all late payment penalties contained in this Agreement, in the
event FRC is the prevailing party.  If the dispute is resolved within this
ninety (90) day period, no late fees will be assessed.

3.4 Late Fees.  Any payments (which are not disputed in accordance with
Paragraph 3.3 above) not received by the Due Date shall bear interest at an
annual rate of eighteen (18) percent, or the maximum rate permitted by law,
whichever is less, from the Due Date until paid in full.  Any payments
received which are less than the total amount due shall be applied first to
interest and collection fees, and then to the oldest invoice(s) outstanding,
regardless of any contrary instructions received from the Customer.

                                  ARTICLE 4
                                  LIABILITY

4.1 Service Interruptions.  FRC shall not be liable for interruptions in the
provisions of Service to Customer caused by or resulting from any act of God,
flood, earthquake, storm, lightning, fire, epidemic, war, outbreak of
hostilities (whether or not war is declared), riot, strikes or other labor
unrest, civil disturbance, sabotage, failures of third parties, including
mechanical failures, fiber or cable cuts, accidents, defects in transmission,
expropriation by governmental authorities, interruptions by regulatory or
judicial authorities or other acts or events that are outside the reasonable
control of FRC.

4.2 LIMITATION OF LIABILITY.  IN NO EVENT SHALL FRC BE LIABLE TO CUSTOMER OR
ANY OTHER THIRD PARTY IN ANY RESPECT, INCLUDING, WITHOUT LIMITATION, FOR ANY
DIRECT, CONSEQUENTIAL, SPECIAL, INCIDENTAL, ACTUAL OR PUNITIVE DAMAGES, OR FOR
ANY LOST PROFITS OF ANY KIND OR NATURE WHATSOEVER, ARISING OUT OF OR RELATING
TO THIS AGREEMENT (OR THE OBLIGATIONS, HEREUNDER).

4.3 NO WARRANTY.  FRC MAKES NO WARRANTY TO CUSTOMER OR ANY OTHER PERSON OR
ENTITY, WHETHER EXPRESS OR IMPLIED OR STATUTORY, AS TO THE QUALITY,
MERCHANTABILITY, COMPLETENESS OR FITNESS FOR A PARTICULAR USE OR PURPOSE OF
THE SERVICES PROVIDED UNDER THIS AGREEMENT, ALL SUCH WARRANTIES HEREBY BEING
EXPRESSLY EXCLUDED AND DISCLAIMED.

                                  ARTICLE 5
                               CONFIDENTIALITY

5.1 Confidentiality.  During the term of this Agreement, the parties may
disclose to each other certain "proprietary" and/or "confidential"
information.  The parties desire to assure the confidential and proprietary
status of the information which may be disclosed to each other and therefore
for themselves and their affiliates agree as follows:

(a) All information disclosed shall be deemed to be confidential and
proprietary (hereinafter "Proprietary Information") provided that written
information is clearly marked in a conspicuous place as proprietary, and
verbal information is immediately confirmed in writing as proprietary.  All
information contained in this Agreement, including the Schedules hereto, as

<PAGE>

information and rate information of either party given to or learned by the
other in connection with this Agreement shall be considered Proprietary
Information without further act of either party.

(b) Each party agrees to use the Proprietary Information received from the
other party only for the purpose of this Agreement.  No other rights, and
particularly licenses, to trademarks, service marks, inventions, copyrights,
or patents are implied or granted under this Agreement.

(c) Proprietary Information supplied shall not be reproduced in any form or
orally communicated except as required to accomplish the intent of this
Agreement.

(d) The receiving party shall provide at a minimum the same care to avoid
disclosure or unauthorized use of the Proprietary Information as it provides
to protect its own proprietary information.  It is agreed that all Proprietary
Information shall be retained by the receiving party in a secure place with
access limited to only such of the receiving party's employees or agents who
need to know such information for purposes of this Agreement.

(e) All Proprietary Information, unless otherwise specified in writing, shall
remain in the property of the disclosing party, shall be used by the receiving
party only for the purpose intended, and such Proprietary Information,
including all copies thereof, shall be returned to the disclosing party or
destroyed after the receiving party's need for it has expired or upon written
request of the disclosing party, and, in any event, upon termination of this
Agreement.  The non-disclosing party shall promptly provide the disclosing
party written certification that all Proprietary Information has been returned
or destroyed.

(f) It is understood that the term "Proprietary Information" does not include
information which:

     (1) has been lawfully published or is otherwise in the public domain
through no fault of the parties;

     (2) prior to disclosure is properly within the legitimate possession of
the receiving party without restriction of the receiving party's right to
disseminate the information and without notice of any restriction against its
further disclosure;

     (3) subsequent to disclosure is lawfully received from a third party
having rights therein without restriction of the third party's right to
disseminate the information and without notice of any restriction against its
further disclosure;

     (4) is independently developed without breach of any obligation of
confidentiality through parties who have not had, either directly or
indirectly, access to or knowledge of such Proprietary Information;

     (5) is disclosed with the prior written approval of the other party; or

     (6) is obligated to be produced under order of a court of competent
jurisdiction or other legal or regulatory process or procedure, provided that
the party who is requested to produce the Proprietary Information shall
promptly notify the other party in writing of the request.

5.2 Use of Name.  Each party agrees that, without the other party's written
consent, it will not use the name, service marks or trademarks of the other
party or of any of its affiliated companies in any advertising publicity
releases or sales presentations.  Neither party shall take any actions which
will in any manner compromise other party's registered trademarks and/or

("Customer") agrees to purchase from FRC, Inc. ("FRC"), and FRC agrees to sell
to Customer, the long distance telephone services "the "Carrier Service") set
forth in Exhibit 1 at the stated rates, with the understanding that such
Customer is responsible for delivering its calls or other services to FRC's
switching site at 60 Hudson Street, New York, New York, 10022, or such other
points and locations as may be mutually agreed upon.

A.2 Rate Changes.  FRC reserves the right t adjust its rates at any time upon
five(5) days' prior written notice to Customer, and Customer's continued use
of the Carrier Service constitutes acceptance of the rates and Customer's
agreement to pay all applicable charges.

A.3 Payment Security.  Upon the request of FRC, Customer shall provide
financial statements, credit reports and other publicly available financial
information reasonably requested by FRC to determine Customer's
creditworthiness.  If requested by FRC, Customer shall provide a cash deposit,
a letter of credit drawn on a financial institution acceptable to FRC or such
other security as FRC and Customer may agree upon prior to FRC rendering any
Service to secure Customer's payments during the term that Services are
provided hereunder.  Subject to Section 3.3 of the Agreement, FRC may offset
against the security any amounts due under the Agreement by Customer that are
not paid when due.  Upon the expiration or termination of the Agreement for
any reason, FRC shall have the right to offset against the security any
amounts owed to it by Customer and shall remit the balance promptly to
Customer without interest.

A.4 Applicability of Tariffs and Laws.  Service provided hereunder and the
rights and obligations of the parties hereunder may be subject to and be
governed by tariffs filed by FRC from time to time with the Federal
Communications Commission or any applicable regulatory authority
(collectively, the "Tariffs"), the terms of which are incorporated herein by
reference.  If there is any conflict or inconsistency between the terms of the
Agreement and any of the Tariffs applicable to this Agreement, the terms of
the Agreement shall control.  The Tariffs are subject to modification in
accordance with applicable law and the rules and regulations of applicable
regulatory authorities.  The provision of Service under this hereunder also is
subject to applicable law and the rules and regulations of applicable
regulation authorities.  Each party shall perform its obligations hereunder in
compliance with applicable laws.

A.5 Resale of Services.

(a) In reselling FRC's Services under this Agreement, Customer will observe
the highest standard of integrity and fair dealing with members of the public.
Customer agrees to sell and bill FRC's Service under its own name, identity or
mark, and Customer further agrees not to reference FRC's name or marks in any
context involving its furnishings of service(s) to the public.  If any
violation of this provision occurs during the term of this Agreement, FRC may
terminate this Agreement on five(5) business days written notice.
Furthermore, Customer agrees to indemnify FRC for any actions, claims, suits
or damages arising out of any allegation that if proved would cause Customer
to be in breach of this provision and Customer shall also pay all attorney's
fees and costs incurred by FRC due to any actions, claims, suits or damages
arising out of such allegation.

(b) Customer agrees that it will obtain and maintain any and all approvals to
resell FRC's Service hereunder from the FCC, including requirements imposed by
Section 214 of the Communications Act of 1934, as amended, and state
regulatory bodies.  In the event Customer fails to botain or maintain the
appropriate approvals, FRC shall not be liable for any delay or failure to
provide FRC's Services.

(c) Customer shall have sole responsibility for interacting with its customers
in all matters pertaining to service, including the placing and handling of
service orders, service installation, operation and termination, dispute
handling and resolution, and billing and collection matters.  FRC shall incur

<PAGE>

no obligation, nor shall it be deemed to have any obligation, to interact with
Customer's customers for any reason or purpose.  Customer shall cooperate with
FRC as necessary to address and resolve service-related issues and problems
and shall impose upon its customers an obligation to cooperate, with Customer
in addressing and resolving service-related issues and problems.

(d) Customer understands and accepts that, as part of FRC's normal business
policy and practices and its obligations under law, FRC will engage in
extensive marketing efforts in attempt to sell its services to the public and
that such efforts will result in active competition with Customer for the
business of users who are Customer's customers or prospects.  Accordingly,
Customer further understands and accepts that such competition by FRC is in
all respects fair and proper and that Customer shall not complain, or be heard
to complain, of business lost to FRC.  Under no circumstance shall any
inference be derived that FRC's entry into this Agreement with Customer means
that FRC will restrict its efforts to compete against Customer in any way.

(e) Customer understands and accepts that no fiduciary relationship arises by
virtue of this Agreement and that, accordingly, FRC incurs non of the
obligations that arise in such relationship as an incident of its fulfilling
its obligations under this Agreement.  Further, Customer understands and
accepts that FRC is not an insurer of profits for Customer, nor does FRC
guarantee the success of Customer's business as a result of Customer's receipt
of service(s) under this Agreement.

A.6 Fraudulent Calls.  FRC shall not be liable for any fraudulent calls
delivered to FRC and billed to Customer's account.  FRC shall notify Customer
promptly of any fraudulent calling of which FRC has knowledge, it being
understood that FRC is under no obligation to investigate the authenticity of
calls charged to Customer's account.

IN WITNESS WHEREOF, the parties accept this Schedule A to the Carrier Services
Agreement dated May 29, 1998 between FRC and Customer as of this 29th day of
May, 1998.
