     (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

     Commission ("FCC"), the applicable public utility commission ("PUC") and
     the applicable LEC), for each ANI indicating the consent of such end user

     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.

     (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

     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
     Cancellation Charge as described in Section 2 above.

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

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

                     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:

     Attachments attached to the TSA, commencing as of November  1, 1999 and

     force and effect throughout the Service Term and any extensions thereof.
