         for 1+ and TOLL FREE calls within the State of Texas will be $0.1175.

C.       DISCOUNT SCHEDULE/APPLICATION OF DISCOUNTS/RATES. Commencing with
         Customer's December, 1998 billing period (i.e., January, 1999 invoice),
         be parties agree to delete the Rate and Discount Schedule attached to
         the TSA in its entirety and replace said Schedule with the Amended and
         Restated Rate and Discount Schedule attached hereto.

         herein, the terms and conditions of the TSA and the PET will remain in

                                 III. APPLICATION OF DISCOUNTS

(A) After determining Customer's applicable Discount percentage under Article II
above, the applicable percentage will be applied to Monthly Revenues comprised
of Customer's INTERSTATE (including Alaska, Hawaii, the United States Virgin
Islands and Puerto Rico UNLESS otherwise noted herein) measured usage charges
(which includes 1+ and Toll Free usage UNLESS otherwise noted herein).

(B) During the Service Term, accumulated credits derived from the applicable
Discount will be applied in arrears commencing with the first day of the month
following the Effective Date, that is, the Discount will be applied to
Customer's measured usage charges for the preceding month (the "DISCOUNT
PERIOD"). The initial Discount Period shall include any partial calendar month
following Start of Service, or such other time basis as may be mutually
determined by the parties.

<PAGE>

(C) Each Discount will result in the application of a credit obtained during the
Discount Period to the WorldCom invoice to Customer relevant to the billed
measured Switched Service for the calendar month next following the completion
of each Discount Period, PROVIDED Customer has paid undisputed charges
(including any late fees, if applicable) for that month and has not otherwise
been subject to a Suspension Notice in accordance with the TSA. Failure of
Customer to comply with the foregoing provision shall entitle WorldCom to
withhold any credit due Customer for the Discount Period in question until such
charges (including late fees) have been paid in full.

         IN WITNESS WHEREOF, Customer has initialed this CLASSIC SWITCHED
SERVICES Amended and Restated Rate and Discount Schedule on the date first
written above.

                         WORLDCOM NETWORK SERVICES, INC.

                      CLASSIC/TRANSCENDTM SWITCHED SERVICES

                              AMENDED AND RESTATED
                                SERVICE SCHEDULE

         THIS AMENDED AND RESTATED SERVICE SCHEDULE is made by and between
WorldCom Network Services, Inc. ("WORLDCOM") and Logix Communications
Corporation ("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
                  World Com 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 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 World Com network at one or more World Com POP(s)
         must be established ("DEDICATED SERVICE INTERCONNECTIONS"). Each
         Carrier Service Interconnection and Dedicated Service Interconnection
         shall be comprised of

                                        Page 1 of 8
                                       CONFIDENTIAL
<PAGE>

         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 World Com 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
         World Com 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 World
         Com or any third party solely for the purpose of verifying Customer's
         interstate/intrastate minutes of traffic. Customer agrees to indemnify
         World Com for any liability World Com 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 World Com'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 World
         Com'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 D$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 carder, WorldCom will have the authority to direct
         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 World Com. The monthly recurring

                                       Page 2 of 8
                                      CONFIDENTIAL

<PAGE>

         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 following 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 DS1 (or DS-1 equivalent circuit) of
         not less than an average of $1,500 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., $1,500) 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 $3,500, Customer's actual
                  Switched Services measured usage charges for 2 DS-1s
                  comprising a Carrier Service Interconnection at WorldCom POP B
                  is $4,500, 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 $600. Customer
                  would not be subject to a Minimum Usage Charge since
                  Customer's actual Minimum Monthly Usage is $8,600 which
                  exceeds Customer's Minimum Monthly Usage of $7,500 [5 x
                  $1,500).

         (h) DS-1 circuits comprising all Service Interconnections will be
         subject to a nonrecurring $400 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 World Com 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
World Com's request which shall not be more frequent than once every three (3)
months.

8.       TOLL FREE NUMBERS:

         (a) TOLL FREE numbers will be issued to Customer (i.e., issuance
         equates to activation or reservation, whichever occurs first) on a
         random basis. Customer requests for specific numbers will be considered
         by WorldCom, and if provided, will be subject to additional charges as
         set forth below and WorldCom's then current reservation policy which
         shall also apply to any randomly selected and reserved TOLL FREE
         number. At any time preceding three (3) months from the scheduled
         expiration of the Service Term, Customer may only reserve TOLL FREE
         numbers in an amount equal to the greater of (i) 50, or (ii) fifteen
         percent (15%) of the total number of TOLL FREE numbers activated by
         WorldCom for Customer. Customer requests for TOLL FREE numbers
         inconsistent with the above stated conditions may be considered by
         World Com on an individual case basis. TOLL FREE numbers reserved for
         Customer will be activated upon Customer's request,

         which a TOLL FREE number is reserved for or otherwise assigned to
         Customer, that Customer will not seek any remedy from WorldCom under
         a theory of detrimental reliance or otherwise that such TOLL FREE
         number(s) are found not to be available for Customer's use until such
         TOLL FREE number is put in service for the benefit of Customer, and
         that such TOLL FREE number(s) shall not be sold, bartered, brokered or
         otherwise released by Customer for a fee (TOLL FREE Number
         Trafficking"). Any attempt by Customer to engage in TOLL FREE Number
         Trafficking shall be grounds for reclamation by WorldCom for
         reassignment of the TOLL FREE number(s) reserved for or assigned to
         Customer.

2.       SERVICE INTERCONNECTIONS:

         (A) In order to utilize ADVANCED TOLL FREE Service, one or more full
         time dedicated connections between Customer's network and the MCI
         WorldCom network at one or more MCI WorldCom POP(s) must be established
         ("SERVICE INTERCONNECTION(S)"). Each Service Interconnection shall be
         comprised of one or more dedicated access circuits, as the case may be.

         (B) The circuit(s) comprising each Service Interconnection to a MCI
         WorldCom POP shall be requested by Customer on the appropriate MCI
         WorldCom Service Request. Each Service Request will describe (among
         other things) the MCI 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
         originating or terminating switch location, as the case may be. Such
         additional information may be obtained from Customer or gathered by MCI
         WorldCom and recorded in Technical Information Sheets provided by MCI
         WorldCom.

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

         (D) Customer shall be solely responsible for establishing and
         maintaining each Service Interconnection over facilities subject to MCI
         WorldCom's approval. Service Interconnections shall be only comprised
         of DS-1 facilities unless otherwise provided for in the Service Request
         and agreed to in writing by MCI WorldCom. If a Service Interconnection
         is proposed to be

                                       Page 2 of 3

<PAGE>

         made via a local exchange carrier, MCI WorldCom will have the authority
         to direct Customer to utilize MCI WorldCom's entrance facilities or
         local serving arrangement ("LSA") with the relevant local telephone
         operating company, and Customer will be subject to a nondiscriminatory
         charge therefor from MCI WorldCom. The monthly recurring charge
         relevant to Customer's use of LSA capacity shall be subject to upward
         adjustment by MCI 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.

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

         (F) Commencing with the second full calendar month following Start of
         Service for each circuit comprising a Service Interconnection 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 $1,500 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,
         MCI WorldCom will charge and Customer will pay the difference between
         the total combined number of DS-1s times the Minimum Monthly Usage
         (i.e., $1,500) and Customer's total combined Switched Services measured
         usage charges for the circuit(s) comprising the Service Interconnection
         in question ("MINIMUM USAGE CHARGE").

         (G) DS-1 circuits comprising all Service Interconnections will be
         subject to a nonrecurring $400 per DS-1 switch port installation charge
         (provided the maximum charge hereunder will be $2,000 for up to 28 DS-1
         s ordered at the same time), and DS3 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.       OTHER TERMS AND CONDITIONS. Except as specifically amended or modified
         herein, the terms and conditions of the Agreement will remain in full
         force and effect throughout the applicable Service Terms and any
         extensions thereof.

         IN WITNESS WHEREOF the parties have entered into this Amendment No. 2
as of the date first written above.

                         WORLDCOM NETWORK SERVICES, INC.

                    ATTACHMENT FOR ADVANCED TOLL FREE SERVICE

         This ATTACHMENT FOR ADVANCED TOLL FREE SERVICE is made by and between
Logix Communications Corporation ("CUSTOMER") and WorldCom Network Services,
Inc. ("MCI WORLDCOM") and is a part of their Telecommunications Services
Agreement for Switched Services. Capitalized terms not defined herein shall
have the meaning ascribed to them in the TSA, the PET, the applicable
Attachment(s) or the Tariff (as defined below), whichever is applicable. NOTE:
ANY MODIFICATIONS, ADDITIONS OR DELETIONS FROM THIS ATTACHMENT WILL NOT BE
EFFECTIVE UNLESS SPECIFICALLY SET FORTH IN THE PET.

         During the Service Term of the Agreement, MCI WorldCom will provide
"ADVANCED TOLL FREE SERVICE" which is MCI WorldCom's origination of calls and
the termination of such calls to Customer's Carrier PLUS Service
Interconnection(s) (as defined in the PET), (i) to and from the locations
below, and (ii) for the charges and applicable discounts set forth herein.
With respect to Domestic Interstate and International ADVANCED TOLL FREE
Service, this Attachment incorporates by reference the terms of MCI Tariff FCC
No. 1 (the "TARIFF'), which may be modified from time to time by MCI WorldCom
in accordance with law and thereby affect the Services furnished Customer
hereunder, except that the terms and conditions contained in the TSA, the PET
or this Attachment shall supplement or, to the extent inconsistent, supersede
the Tariff terms and conditions. With respect to Intrastate ADVANCED TOLL FREE
Service, this Attachment incorporates by reference each applicable state
tariff filed by MCI WorldCom, which may be modified from time to time by MCI
WorldCom, and thereby affect the Services furnished.

         For purposes of this Attachment "ORIGINATING LEC" shall mean the LEC
from which an inbound call originates based upon the NPA/NXX designations, or
complete ANI systems if and when the capability is developed to process such
information, as determined in the Local Exchange Routing Guide (LERG).

I.       TERMS AND CONDITIONS.

         (A)   FORECASTS: Before Customer's initial order for ADVANCED TOLL
         FREE Services, Customer shall provide MCI WorldCom with a forecast
         regarding the number of minutes expected to be originated in various
         LATAs and/or Tandems, so as to enable MCI WorldCom to configure
         optimum network arrangements. IN THE EVENT CUSTOMER'S TRAFFIC VOLUMES
         RESULT IN A LOWER THAN INDUSTRY STANDARD COMPLETION RATE OR OTHERWISE
         ADVERSELY AFFECT THE MCI WORLDCOM NETWORK, MCI WORLDCOM RESERVES THE
         RIGHT TO BLOCK THE SOURCE OF SUCH ADVERSE TRAFFIC AT ANY TIME.
         Customer will provide MCI WorldCom with additional forecasts from
         time to time upon MCI WorldCom's request which shall not be more
         frequent than once every three (3) months.

         (B)   START OF SERVICE: Start of Service for ADVANCED TOLL FREE
         Service will be concurrent with the activation of each circuit
         comprising a Carrier PLUS Service Interconnection relevant to
         ADVANCED TOLL FREE Service.

         (C)   LIMITATION OF ORIGINATION AND TERMINATION LOCATIONS: ADVANCED
         TOLL FREE Service may be originated from locations in the 48
         contiguous United States,

                                       Page 1 of 4

<PAGE>

         Hawaii, Alaska, the US Virgin Islands, Puerto Rico, Guam, North
         Marianas Islands, Canada and International locations as described in
         Schedule PR-B and terminated to any Customer-designated Carrier PLUS
         Service Interconnection.

         (D)   PAY PHONE SURCHARGE: In the event MCI WorldCom is required to
         compensate payphone service providers (PSPs) for toll-free or access
         code calls which originate from payphones (including without
         limitation, any Order adopted by the FCC) ("PAYPHONE SURCHARGE"), MCI
         WorldCom will charge and Customer agrees to pay MCI WorldCom the
         amount of the Payphone Surcharge which is required to be paid by MCI
         WorldCom.

         (E)   TOLL FREE NUMBERS:

               (1)   TOLL FREE numbers will be issued to Customer (i.e.,
               issuance equates to activation or reservation, whichever occurs
               first) on a random basis. Customer requests for specific
               numbers will be considered by MCI WorldCom, and if provided,
               will be subject to additional charges as set forth below and
               MCI WorldCom's then current reservation policy which shall also
               apply to any randomly selected and reserved TOLL FREE number.
               At any time preceding three (3) months from the scheduled
               expiration of the Service Term, Customer may only reserve TOLL
               FREE numbers in an amount equal to the greater of (i) 50, or
               (ii) fifteen percent (15%) of the total number of TOLL FREE
               numbers activated by MCI WorldCom for Customer. Customer
               requests for TOLL FREE numbers inconsistent with the above
               stated conditions may be considered by MCI WorldCom on an
               individual case basis. TOLL FREE numbers reserved for Customer
               will be activated upon Customer's request, however, MCI
               WorldCom may charge Customer an SMS Storage fee for each TOLL
               FREE number.

               (2)   Customer Request for Specific Numbers - $25 per individual
               TOLL FREE number reserved or assigned.

               (3)   Customer specifically agrees that regardless of the method
               in which a TOLL FREE number is reserved for or otherwise
               assigned to Customer, that Customer will not seek any remedy
               from MCI WorldCom including, but not limited to, any remedy
               based on a theory of detrimental reliance or otherwise that
               such TOLL FREE number(s) are found not to be available for
               Customer's use until such TOLL FREE number is put in service
               for the benefit of Customer, and that such TOLL FREE number(s)
               shall not be sold, bartered, brokered or otherwise released by
               Customer for a fee ("TOLL FREE NUMBER TRAFFICKING"). Any
               attempt by Customer to engage in TOLL FREE Number Trafficking
               shall be grounds for reclamation by MCI WorldCom for
               reassignment of the TOLL FREE number(s) reserved for or
               assigned to Customer.

         (F)   RESPORG SERVICES: Responsible Organization Services (relevant to
         TOLL FREE Numbers) if provided by MCI WorldCom will be provided by MCI
         WorldCom pursuant to MCI WorldCom's applicable tariffs (or the
         applicable tariffs of its affiliates).
