                         WORLDCOM NETWORK SERVICES, INC.

                     CLASSIC/TRANSCEND(TM) SWITCHED SERVICES

                                SERVICE SCHEDULE

      This Service Schedule is made this 1st day of November, 1998, by and
between WorldCom Network Services, Inc. ("WorldCom") and Incomnet Communications
Corporation (successor-in-interest to National Telephone & Communications, Inc.)
("Customer") and is a part of their Telecommunication Services Agreement for
Switched Services. Neither Customer nor WorldCom shall be obligated with respect
to the Switched Services described below, nor any other condition of such
Switched Services until Customer has submitted and WorldCom has accepted a
Service Request with respect to the particular Switched Service. Capitalized
terms not defined herein shall have the meaning ascribed to them in the TSA, the
PET or the applicable Rate and Discount Schedule.

1. SWITCHED SERVICES: During the Service Term of the Agreement, WorldCom will
provide the following Switched Services (all as more particularly described
herein), (i) to and from the locations below, and (ii) for the charges and
applicable discounts set forth in the applicable Rate and Discount Schedule
attached herewith:

(a)   "TERMINATION Service" which is WorldCom's termination of calls received
      from Customer's Service Interconnection(s).

(b)   "TOLL FREE ORIGINATION Service" which is the origination of Toll Free
      calls by WorldCom and the termination of such calls to Customer's Service
      Interconnection(s).

(c)   "SWITCHED ACCESS Service" which is the origination (via individual
      telephone access lines) and termination of calls solely over facilities
      comprising the WorldCom network.

(d)   "DEDICATED ACCESS Service" which is the origination and termination of
      calls solely over facilities comprising the WorldCom network which
      origination or termination is via dedicated access lines.

(e)   "TRAVEL CARD Service" which is the origination (via Travel Card Toll Free
      number access) and termination of calls solely over facilities comprising
      the WorldCom network.

2.    SERVICE INTERCONNECTIONS:

      (a) In order to utilize (i) TERMINATION Service and TOLL FREE ORIGINATION
      Service, one or more full time dedicated connections between Customer's
      network and the WorldCom network at one or more WorldCom designated
      locations ("WorldCom POP") must


                                  Page 1 of 8


      be established ("Carrier Service Interconnections"), and (ii) DEDICATED
      ACCESS Service, one or more full time dedicated connections between an End
      User's private branch exchange ("PBX") or other customer premise equipment
      and the WorldCom network at one or more WorldCom POP(s) must be
      established ("Dedicated Service Interconnections"). Each Carrier Service
      Interconnection and Dedicated Service Interconnection shall be comprised
      of one or more dedicated access circuits, as the case may be. Carrier
      Service Interconnections and Dedicated Service Interconnections are
      collectively referred to as "Service Interconnections".

      (b) The circuit(s) comprising each Service Interconnection to a WorldCom
      POP shall be requested by Customer on the appropriate WorldCom Service
      Request. Each Service Request will describe (among other things) the
      WorldCom POP to which a Service Interconnection is to be established, the
      Requested Service Date therefor, the type and quantity of circuits
      comprising the Service Interconnection and any charges and other
      information relevant thereto, such as, Customer's terminating or
      originating switch location, as the case may be. Such additional
      information may be obtained from Customer or gathered by WorldCom and
      recorded in Technical Information Sheets provided by WorldCom.

      (c) Once ordered, and unless otherwise provided for in this TSA, Service
      Interconnections or the circuits comprising each Service Interconnection
      may only be canceled by Customer upon not less than thirty (30) days prior
      written notice to WorldCom.

      (d) With respect to a Carrier Service Interconnection, absent the
      automatic number identification ("ANI") of the calling party, Customer
      shall provide WorldCom with a written certification (the "Certification")
      of the percentage of interstate (including international) and intrastate
      minutes of use relevant to the minutes of traffic to be terminated in the
      same state in which the WorldCom POP is located to which the Carrier
      Service Interconnection is made. This Certification shall be provided by
      Customer prior to Start of Service for any Carrier Service Interconnection
      and may be modified from time to time by Customer and subject to
      recertification upon the request of WorldCom which requests shall not be
      made unilaterally by WorldCom more than once each calendar quarter. Any
      such modification(s) or Certification (s) shall be effective as of the
      first day of any calendar month and following at least forty-five (45)
      days notice from Customer. In the event Customer fails to make such
      Certification, the relevant minutes of use will be deemed to be subject to
      the Intrastate Rates described in the applicable Rate and Discount
      Schedule. In the event WorldCom or any other third party requires an audit
      of WorldCom's interstate/intrastate minutes of traffic, Customer agrees to
      cooperate in such audit at its expense and make its call detail records,
      billing systems and other necessary information reasonably available to
      WorldCom or any third party solely for the purpose of verifying Customer's
      interstate/intrastate minutes of traffic. Customer agrees to indemnify
      WorldCom for any liability WorldCom incurs in the event Customer's
      Certification is different than that determined by the audit.

      (e) With respect to Carrier Service Interconnections, Customer shall be
      solely responsible for establishing and maintaining each Carrier Service
      Interconnection over facilities subject to WorldCom's approval. With
      respect to Dedicated Service Interconnections, WorldCom will provision and
      maintain local access facilities between the End User location (i.e., PBX)
      and the WorldCom POP, subject to any LEC charges plus other applicable
      terms and charges set forth in WorldCom's F.C.C. Tariff No. 5, however,
      Customer may elect to be responsible for establishing each Dedicated
      Service Interconnection over facilities subject to WorldCom's approval.
      Service Interconnections shall only be comprised of DS-1 facilities unless
      otherwise provided for in the Service Request and agreed to in writing by
      WorldCom. If a Service Interconnection is proposed to be made via a local
      exchange carrier, WorldCom will have the authority to direct


                                  Page 2 of 8


      Customer to utilize WorldCom's entrance facilities or local serving
      arrangement ("LSA") with the relevant local telephone operating company,
      and Customer will be subject to a non-discriminatory charge therefor from
      WorldCom. The monthly recurring charge relevant to Customer's use of LSA
      capacity shall be subject to upward adjustment by WorldCom from time to
      time which adjustment, if any, shall not exceed the rate that otherwise
      would be charged for the equivalent switched access capacity between the
      same points by the relevant local telephone operating company pursuant to
      its published charges for the type of service in question.

      (f) If other private line interexchange facilities are necessary to
      establish a Service Interconnection, and such facilities are requested
      from WorldCom, such facilities will be provided on an individual case
      basis.

      (g) Commencing with the second full calendar month folbwing Start of
      Service for each circuit comprising a Service Interconnection (i.e., both
      Carrier Service Interconnections and Dedicated Service Interconnections)
      and thereafter, Customer will maintain Switched Services measured usage
      charges per DS-1 (or DS-1 equivalent circuit) of not less than an average
      of [*] per calendar month/billing period ("Minimum Monthly Usage"). In the
      event Customer fails to obtain the required Minimum Monthly Usage for the
      circuits comprising each Service Interconnection, WorldCom will charge and
      Customer will pay the difference between the number of DS-1s times the
      Minimum Monthly Usage (i.e., [*]) and Customer's total Switched Services
      measured usage charges for the circuit(s) comprising the Service
      Interconnection in question ("Minimum Usage Charge"). WorldCom TERMINATION
      Service and TOLL FREE ORIGINATION Service minutes carried over the same
      Service Interconnection, if any, shall be included in determining if
      Customer has met the Minimum Monthly Usage requirement.

            Example: Assume Customer's actual Switched Services measured usage
            charges for 2 DS-1s comprising a Carrier Service Interconnection at
            WorldCom POP A is [*], Customer's actual Switched Services measured
            usage charges for 2 DS-1s comprising a Carrier Service
            Interconnection at WorldCom POP B is [*], and Customer's End User's
            actual Switched Services measured usage charges for 1 DS-1
            comprising a Dedicated Service Interconnection at WorldCom POP C is
            [*]. Customer would not be subject to a Minimum Usage Charge since
            Customer's actual Minimum Monthly Usage is [*] which exceeds
            Customer's Minimum Monthly Usage of [*] [5 x [*]].

      (h) DS-1 circuits comprising all Service Interconnections will be subject
      to a nonrecurring [*] per DS-1 switch port installation charge, and DS-3
      circuits comprising all Service Interconnections will be subject to a
      nonrecurring per DS-3 switch port installation charge as determined on an
      individual case basis.

3. FORECASTS: Before Customer's initial order for Switched Services, Customer
shall provide WorldCom with a forecast regarding the number of minutes expected
to be terminated or originated in various LATAs and/or Tandems, so as to enable
WorldCom to configure optimum network arrangements. In the event Customer's
Switched Service traffic volumes result in a lower than industry standard
completion rate or otherwise adversely affect the WorldCom Network, WorldCom
reserves the right to block the source of such adverse traffic at any time.
Customer will provide WorldCom with additional forecasts from time to time upon
WorldCom's request which shall not be more frequent than once every three (3)
months.

4. START OF SERVICE: Start of Service for the various Switched Services will
occur as described below:
