 CARRIER AGREEMENT

TERMS AND CONDITIONS

     This Carrier Agreement (the "Agreement"), is between MCI TELECOMMUNICATIONS
CORPORATION ("MCI"), 1801 Pennsylvania Avenue N.W., Washington, D.C. 20006, a   
Delaware corporation, and ASSOCIATED COMMUNICATIONS COMPANIES OF AMERICA (ACCA) 
("Customer"), an association of carriers which are resale common carriers       
subject to the Communications Act of 1934, as amended, with offices located at  
111 Congress Avenue, Suite 3000, Austin, Texas 78701.                           

1.   Scope of Agreement.                                                        

    (a)   A member of ACCA will be referred to herein as a "Member". A list of
     said Members is attached hereto as Exhibit A to this Agreement. Each Member
  must be a signatory to this Agreement in order to receive the benefit of
    this Agreement. New Members of ACCA may be permitted to become signatories
and receive the benefits of this Agreement only through the written   
     amendment of this Agreement, signed by both parties hereto. For purposes of
 this Agreement, all references to "Customer" shall be deemed to include
Customer generally, and each Member individually with respect to its  
individual usage of services hereunder, unless otherwise provided.    

  (b)   MCI will provide to Customer certain specified domestic interstate
    services, international services, and intrastate common carriage services.
For domestic interstate and international services, this Agreement    
  incorporates by reference the terms of MCI Tariff FCC No. 1 on file with
the Federal Communications Commission ("FCC") or any successor to such
tariff ("Tariff"), which may be modified from time to time by MCI in  
accordance with law and thereby affect the services furnished Customer
   under this Agreement, except that the following terms and conditions will
supplement or, to the extent inconsistent, supersede Tariff terms and 
conditions and will remain in effect throughout the Service Term (as  
defined in Paragraph 8(a)). For intrastate services, this Agreement   
    incorporates by reference each applicable state tariff filed by MCI, which
  may be modified by MCI from time to time and thereby affect the services
     furnished Customer. This Agreement is entered pursuant to Section 211(a) of
the Communications Act of 1934, as amended.                           

   (c)   Capitalized terms not otherwise defined in this Agreement will have
the meanings assigned to them in the Tariff.                          

2.   Monthly Commitment.                                                        

  (a)   During each monthly billing period of the Service Term, Customer's
 aggregate "Monthly Usage" for such month (as defined in Paragraph 2(b))
will equal or exceed [_____________] ("Monthly Commitment").          

    (b)   Monthly Usage will mean Customer's usage during each monthly billing
  period of the MCI services in Attachment 1 calculated in accordance with
the following:                                                        

        1)   Customer's usage of domestic interstate and international MCI
    Services (hereinafter "Interstate Services" and "International
         Services") calculated at the rates set forth in Attachment 1, after
   application of all discounts and credits other than discounts
       applicable under Paragraph 5(d) and under Attachment 1, Paragraph
      4(a) hereof (which shall be applied after calculation of Monthly

           Usage), and excluding any applicable taxes (and gross receipts taxes)
         and tax-related surcharges on Interstate Services and International
Services; and                                             

           2)   Customer's domestic intrastate usage of MCI Services at standard
        tariff rates (hereinafter "Intrastate Services") but not including
          any applicable taxes (and gross receipts taxes) and tax related sur-
charges on MCI Intrastate Services.                       

   (c)   Interstate Services, International Services and Intrastate Services
  are collectively hereinafter "MCI Services." The rates for all other MCI
   products and services not explicitly contained within this Agreement will
be governed by the applicable MCI Tariff or applicable state tariff.  

    (d)   If Customer's Monthly Usage is less than the Monthly Commitment in a
     month, for that month: (i) Customer will pay the Customer's actual combined
     monthly recurring and usage charges for MCI Services at standard MCI Tariff
   rates (however, Members will continue to be billed at the rates contained
 in this Agreement); and (ii) an underutilization charge (which Customer
agrees is reasonable) equal to [___________________] of the difference
between the Monthly Commitment and Customer's Monthly Usage. All      
    underutilization charges shall be billed both to ACCA and to Members. ACCA
     shall be responsible for paying all such underutilization charges. However,
Customer's liability under this Paragraph 2(b) shall be limited to the
amount of the Monthly Commitment. Members shall not be liable for     
underutilization in any month that the overall Monthly Usage equals or
exceeds the Monthly Commitment.                                       

(e)   If for any monthly billing period during the Service Term MCI   
 overbills any or all Members for MCI Services and subsequently corrects
   that billing, reducing the amount of the bill(s), and if Customer reduces
  its usage of MCI Services as a direct result of such overbilling, and if
Customer's usage reduction was calculated reasonably, based on the    
     overbilling, to maintain Customer's Monthly Commitment, MCI will not assess
any charges under Paragraph 2(d) above for any month in which         
 underutilization charges are due until sixty (60) days from the date on
     which MCI provides rebill information that reduces the actual monthly usage
below the Monthly Commitment.                                         

3.   Rates and Additional Terms.                                                

     (a)   Customer will pay the rates and charges for MCI Services set forth in
the Attachment(s) and Exhibit(s) to this Agreement and agrees to the  
additional terms and conditions set forth in such Attachment(s) and   
Exhibit(s).                                                           

  (b)   Pursuant to Section 276 of the Telecommunications Act of 1996, the
     Federal Communications Commission has prescribed regulations that establish
a compensation plan to ensure that all payphone service providers are 
    compensated for completed calls from a payphone. MCI reserves the right to
 adjust MCI's rates, including the rates herein, or to impose additional
     charges or surcharges in order to recover amounts MCI is required to pay to
payphone service providers pursuant to Section 276 and the regulations
    implementing Section 276, and any costs incurred by MCI in connection with
such compensation requirement.                                        

(c)   MCI International Rate Review.                                  

     The rates for international services contained herein will be fixed for the
  first three (3) months of the Service Term (as defined in Paragraph 8(a)
below). After such three (3) month period, MCI will have the option to
     revise the rates for any international services contained herein on fifteen
(15) days prior written notice.                                       

(d)   International Call Back Limitations.                            

        1)   If MCI detects the use of "polling" technique by Customer for
      signaling, setup or completion of calls, MCI may, subject to and
without limitation upon the Tariff, block calls.

        2)   If any action or ruling by the FCC or foreign PTTs prevent or
           impede MCI from performing any material obligation in this Agreement,
          MCI may, at MCI's option and upon ten (10) days prior written notice
     to Customer, terminate the affected services herein without any
liability.                                                

        3)   MCI will not be considered in breach of this Agreement if any
           action or ruling by the FCC or foreign PTTs prevents or affects MCI's
           ability to provide MCI Services. In addition, MCI's actions resulting
          from the PTTs blocking or interrupting MCI's Service, or threatening
  to do so, will not be considered a breach of this Agreement.

4.   Security.                                                                  

     (a)   Nothing contained herein shall limit or be interpreted to limit MCI's
     rights as provided for in Section B-7.04 of the Tariff to require, in MCI's
sole discretion based upon MCI's reasonable review of Customer's or   
Member's financial condition, alternative or additional security from 
 Customer. Customer's failure or refusal to comply with such requirement
upon MCI's request therefor may result in the cancellation of this    
   Agreement and Customer's service for cause pursuant to Section B-11.01 of
    the Tariff. The security arrangements provided for hereunder shall survive
    the expiration of the Service Term, as defined herein, and shall remain in
     effect so long as Customer uses MCI Services or has any outstanding balance
due for use of MCI Services.                                          

(b)   Letter of Credit                                                
----------------                                          

       1)   Consistent with Section B-7.04 of the Tariff and in specific
        implementation of such Tariff provision, MCI will conduct a credit
     review of each Member within fifteen (15) days of such Member's
         execution of this Agreement. Based upon the results of such review,
         each Member may be required, as a condition precedent to receipt of
MCI Services hereunder, to provide a security deposit or  
         unconditional letter of credit in a form and from a bank acceptable
          to MCI. If required, such security deposit or letter of credit shall
      be equal to up to [____________________________________] by such
          Member or such other amount as MCI may reasonably require, and shall
           be provided to MCI no later than ten (10) days following MCI's demand
for such security.                                        

         2)   MCI shall have no obligation or liability under this Agreement
          and shall not accept any orders from a Member or provide such Member
          with any MCI Services until the security deposit or letter of credit
        described in Paragraph 4(b)1) immediately above has been provided.
          MCI may immediately terminate its obligation to provide service to a
           Member pursuant to this Agreement without liability in the event that
           such Member fails to provide the security deposit or letter of credit
        described in Paragraph 4(b)1) within ten (10) days of MCI's demand
          for such security. Any waiver of the provisions of this paragraph by
        MCI must be delivered by an authorized executive officer of MCI in
     writing, and no waiver shall be deemed to occur by other means,
 including course of action or other forms of communication.

5.   Payment.                                                                   

   (a)   Before the first day of each usage month each Member shall pay MCI,
     as an estimate of the amount of usage charges to be incurred for such usage
     month, an amount equal to such Member's most recent MCI invoice. If, at the
   beginning of the Service Term, such Member has not received any prior MCI
   invoices at the time payment is due, the Member shall pay an amount equal
  to such Member's reasonable estimate of its usage of MCI Services during
the usage month.                                                      

   (b)   After each usage month each Member shall receive an MCI invoice for
MCI Services provided to such Member under this Agreement. If Member's
    estimated payment made pursuant to Paragraph 5(a) above is less than MCI's
     invoice ("shortfall") such Member shall pay the shortfall amount within ten
    (10) days after receipt of the invoice. If Member's estimated payment made
   pursuant to Paragraph 5(a) above is greater than MCI's invoice ("excess")
MCI shall credit the excess to such Member's next MCI invoice.

   (c)   All payments by Members under this Agreement shall be by electronic
  funds transfer, overnight check or by other means approved in advance by
MCI in writing. A Member's failure to pay either the amount due under 
Paragraph 5(a) above before the first day of the usage month or any   
  shortfall under Paragraph 5(b) above within 10 days after receipt of the
   invoice may result in (i) the exercise of MCI's rights under the security
     provisions contained in Paragraph 4(a) immediately above, (ii) the exercise
  of MCI's rights under Tariff Section B-11.01 with respect to termination
of service to such Member under this Agreement; and/or (iii) MCI's    
  application of any amount owed by MCI to such Member, whether under this
    Agreement or otherwise, to satisfy all or a portion of the amounts owed to
MCI by such Member under this Paragraph 5.                            

 (d)   If MCI receives the estimated prepayment due under Paragraph 5(a)
 above, in immediately available funds, not more than three (3) business
days from the date due, then such Member shall receive an additional  
  [_________________________] discount on its Monthly Usage charges during
   such month. Such discount shall be reflected on such Member's invoice for
    such month, after application of all other discounts and credits that such
    Member may be entitled to under MCI's tariffs or this Agreement, and shall
   be applied as a credit against such Member's interstate and international
Monthly Usage charges.                                                

   (e)   The termination of service to any Member under this Agreement shall
 not affect Customer's Monthly Commitment as described in Paragraph 2(a)
    above. Notwithstanding any other provision contained in this Agreement, it
is understood and agreed that Customer shall have no liability for the
payment of charges owed to MCI by a defaulting or terminated Member.  

  (f)   Customer and each Member understands and acknowledges that, in the
event MCI terminates Carrier Network Services to a Member, whether for
    nonpayment or otherwise, that Member's customers or endusers ("Endusers"),
   may be unable to make calls via MCI's network. If an Enduser is unable to
   make calls via MCI's network, MCI shall have no duty to interact with the
   Enduser in connection with the furnishing of telecommunications services.
    Customer and Member understand and accept that, as a result of Member's or
Member's agent's failure to provide alternate service to Endusers upon
     termination of service, that an Enduser may elect to become an MCI customer
and that MCI shall have no responsibility or liability to Customer or 
Member as a result thereof.                                           

6.   Dispute Resolution.                                                        

     (a)   Any claims or disputes, including billing disputes, arising out of or
related to this Agreement shall be made within six (6) months of their
   occurrence. Any dispute arising out of or related to this Agreement which
    can not be resolved by negotiation will be resolved by binding arbitration
in accordance with the rules contained in MCI Tariff FCC No. 1        
     ("Arbitration Rules"). Neither party may seek injunctive relief of any kind
prior to the confirmation of an arbitration award, except that MCI may
    seek injunctive relief against Customer for violation of Paragraphs 19 and
21 herein.                                                            

    (b)   Independent of Customer's payment obligations set forth in Paragraph
   5, Customer will make a separate claim in writing, with adequate support,
    for any service interruption credit to which Customer believes Customer is
     entitled, and MCI and Customer will promptly address and attempt to resolve
    the claim. In the event the parties are unable to resolve any claim within
     two (2) weeks of the date such claim is received by MCI (or a longer period
    if mutually agreed upon in writing by MCI and Customer), the parties will:

        1)   Consent to mandatory arbitration of all disputes amounting to
        [______________________________] or more. Such arbitration will be
  governed by the Commercial Arbitration Rules of the American
         Arbitration Association, 1739 Rhode Island Avenue, N.W., Suite 509,
   Washington, D.C. 20036 ("AAA"), as amended by this Agreement.

          2)   In the event of a dispute that Customer and MCI cannot resolve,
       either MCI or Customer may notify AAA at the above address of the
          dispute and provide a copy of this Agreement. MCI will provide AAA a
copy of the Tariff in effect at the time of the dispute.

         3)   The party which first gives notice of the dispute will deposit
           with AAA the administrative fee required by AAA's rules and a further
           deposit of [__________________________________________] to secure the
           payment of expenses and fees to the arbitrator. The party which first
           gives notice will send a copy of the notice to the other party, which
         will upon receipt of such notice deposit [_________________________
      _______________] to secure its half of the arbitrator's fees and
expenses.                                                 

         4)   Customer acknowledges that Customer will not withhold any sums
          invoiced unless MCI agrees in advance to the withholding of disputed
       sums in writing. Customer will pay all invoiced sums and then may
    seek a refund in arbitration, in which event MCI will take all
reasonable steps to expedite the arbitration process.     

       5)   The arbitrator will be selected under AAA rules from among a
  panel of seven (7) telecommunications attorneys, retired FCC
employees, and law professors, all of whom will be neutral
         arbitrators under AAA rules. MCI will provide the list of seven (7)
        arbitrators to AAA and will update the list semiannually. AAA will
        select the arbitrator to hear the dispute from among the seven (7)
members of the panel.                                     

           6)   Within twenty (20) days of receipt of notice of the dispute, the
           other party will submit a written response to AAA, which will forward
         the notice and the response to the arbitrator. Within ten (10) days
        of receipt of the notice and the response, the arbitrator will set
the time and place of the hearing.                        

     7)   Customer and MCI expressly recognize that the arbitrator's
          authority is limited to resolution of disputes under this Agreement,
     the Tariff, and any other documents signed by both parties. The
         arbitrator's decision will follow the plain meaning of the relevant
           documents and will be final. In no event will the arbitrator have the
         authority to make any award that provides for punitive or exemplary
damages.                                                  

7.   Termination for Insolvency.                                                

In the event Customer or any Member becomes or is declared insolvent or         
bankrupt, is the subject of any proceedings related to Customer's or Member's   
liquidation, insolvency or for the appointment of a receiver or similar officer 
for Customer or Member, makes an assignment for the benefit of all or           
substantially all of Customer's or Member's creditors, or enters into an        
agreement for the composition, extension, or readjustment of all or             
substantially all of Customer's or Member's obligations, MCI may, by giving     
written notice thereof to Customer or Member, terminate this Agreement in whole 
or in part, with respect to such Member(s), as of a date specified in such      
notice of termination.                                                          

8.   Term.                                                                      

   (a)   The term of this Agreement ("Service Term") will begin on September
1, 1997 ("Effective Date"), provided this Agreement is executed and   
  delivered to MCI by ACCA on or before September 17, 1997. Otherwise, the
Effective Date will be the first day of the first full month following

(b)   If Customer's total actual Monthly Usage accrued hereunder after

 of the Service Term have expired prior to the date of such termination.
  Notwithstanding anything in this Agreement to the contrary, if notice of
  termination is provided pursuant to this Paragraph, but Customer's total
 actual Monthly Usage as of the designated termination date is less than
    [________________________________], Customer shall pay to MCI, in addition
     to all unpaid charges incurred through the termination date, the difference
    between [_________________________________] and Customer's aggregate total
of Monthly Usage through such date.                                   

9.   Expiration of Term.                                                        

Upon expiration of the Service Term of this Agreement, Customer or MCI may      
terminate this agreement by providing the other party sixty (60) days prior     
written notice. If neither party provides such notice within sixty (60) days    
before the expiration of the Service Term, the Service Term will be extended on 
a monthly basis until two (2) full months following the provision of such notice
by either party. Customer will be fully subject to all the terms and conditions,
including standard tariff rates, set forth in the Tariff and respective state   
tariffs for MCI Services received by Customer after this Agreement is           
terminated.                                                                     

10.  Termination Liability.                                                     

Except as otherwise provided in Paragraph 8(b) above, if Customer terminates    
this Agreement before expiration of the Service Term, or if MCI terminates this 
Agreement before expiration of the Service Term for Customer's material breach, 
Customer will pay MCI within thirty (30) days of the effective date of such     
termination an amount equal to [___________________] of the aggregate of        
Customer's remaining Monthly Commitment for each month remaining in the Service 
Term after termination (and a pro rata portion thereof for any partial month),  
together with any previously incurred charges which remain unpaid as of such    
termination date. In addition to the above liability for early termination,     
Customer will pay the termination liability for early termination of all        
tariffed discount plans in which the Customer has enrolled. Charges payable by  
Customer under this Paragraph 10 are not exclusive of any other rights or       
remedies to which MCI may be entitled with respect to any breach or failure by  
Customer. ACCA will be billed for all termination charges.                      

11.  Nondisclosure.                                                             

Neither Customer nor Members will disclose to any third party during this       
Agreement, or during the three (3) year period thereafter, any of the terms and 
conditions set forth in this Agreement unless such disclosure is lawfully       
required by any federal governmental agency or is otherwise required to be      
disclosed by law, or is necessary in any proceeding establishing rights and     
obligations under this Agreement. MCI reserves the right to terminate this      
Agreement for the Member(s) involved in the disclosure immediately upon         
delivering written notice to Customer and such Member of any impermissible third
party disclosure hereunder.                                                     

12.  Notices.                                                                   

All notices, reports and other communications pursuant to or in connection with 
this Agreement will be sent via personal delivery, registered or certified mail 
(return receipt requested), or courier service. All such communications will be 
addressed to the respective party at its address shown below:

Members shall appoint MCI as Customer's agent pursuant to a Letter of Agency in 
substantially the form attached hereto and incorporated herein as Attachment 3  
to this Agreement

When applicable, Members shall certify that any special access lines used in

15.  Tax Exemption.                                                             

When applicable, Members shall certify that such Members are exempt from        
federal, state, and/or local taxes.

This Agreement, including all matters relating to the validity, construction,   
performance and enforcement thereof, shall be governed by the laws of the State 
of New York without giving reference to its principles of conflicts of law,     
except to the extent the Communications Act of 1934, as amended and as          
interpreted and applied by judicial and regulatory authorities, including the   
Federal Communications Commission applies.                                      

17.  Assignment.                                                                

     (a)   This Agreement will be binding on MCI, Customer, Member(s), and their
   respective successors and assigns. Except as otherwise permitted pursuant
to this Paragraph 17, MCI, Customer and Members shall not assign this 
Agreement, whether by operation of law or otherwise, without the prior
     written consent of the other party, which consent shall not be unreasonably
withheld.

 conduct a review of the assignee based on MCI's prior business dealings
  with such entity, and MCI will review the financial credit worthiness of
  the entity. Customer nor Member will assign the agreement if MCI opposes
   the assignment in its reasonable discretion based on MCI's prior business
     dealing's with the entity or if the assignee fails to meet MCI's reasonable
credit worthiness standards.

  (d)   If Customer or a Member assigns this Agreement without MCI's prior
  written approval when such approval is required under this Paragraph 17,
MCI shall be entitled to terminate this Agreement for cause.          

(e)   MCI may terminate its obligation to provide services to a Member
  under this Agreement without liability on ten (10) business days written
    notice in the event that such Member undergoes a merger involving a change
   of control, or divests itself of all or a substantial portion of Member's
telecommunications business, or undergoes a change of more than fifty 
   percent (50%) of Member's ownership. The provisions of this Paragraph (e)
shall not be applicable with respect to mergers or other transactions 
     between a parent and a subsidiary, provided that the surviving entity shall
   assume and acknowledge responsibility for all past and future obligations
     of the prior obligor entity hereunder. This Paragraph (e) shall also not be
applicable with respect to the possible acquisition of Consolidated   
Communications, Inc., by McLeod Telephone.                            

18.  No Waiver.                                                                 

No waiver of any of the provisions of this Agreement will be binding unless it  
is in writing and signed by the party making the waiver. No waiver shall be     
deemed, or shall constitute, a waiver of any other provision, whether or not    
similar, and no waiver shall be deemed, or shall constitute, a continuing       
waiver.                                                                         

19.  Carrier Network Service.                                                   

(a)   In order to be eligible to purchase MCI Carrier Network Services
(hereinafter "CNS"):                                                  

          1)   Except in areas where service origination is not available from
         access providers via a Carrier Identification Code ("CIC"), Members
           will originate all CNS switched outbound traffic and all CNS operator
      services traffic via ANIs with the Primary Interexchange Carrier
         ("PIC") designated to Member's own CIC. Member will submit to MCI a
  list of Local Exchange Carrier ("LEC") end offices requiring
        installation and routing of Member's CIC ("CIC Installation"). MCI
           will invoice Member for the cost of CIC Installation for such LEC end
       offices. MCI will not initiate the CIC Installation process until
   Member pays the invoiced CIC Installation charges, subject to
          application of any installation credits available to Member pursuant
         to Attachment 1, Paragraph 4(b) hereof. Installation and routing of
     Member's CIC may not be supported by MCI in all LEC end offices
          because of excessive requirements for CIC loading and administrative
       demands by such LEC, in the determination of MCI. MCI requires at
          least sixty (60) days prior written notice from Member to deactivate
     or change the translation for sub CIC routing at any end office
           and/or tandem. MCI will handle all Authorized Service Requests (ASRs)
        submitted to the appropriate LEC(s) for MCI's CNS. MCI will not be
          liable for any act or omission of any LEC, including but not limited
          to translation failures resulting from the LECs processing the ASRs.
        In addition, Member will be financially responsible for payment of
        all fees charged by the local exchange carrier related to the ASRs
       submitted to modify the sub-CIC routing and migrate traffic to or
from MCI's network.                                       

           2)   Customer will comply with Section 64.1100 of the FCC's Rules and
  Regulations, as well as other applicable laws or regulations
          pertaining to the sale and delivery of telecommunications service(s)
   to Customer's customers. MCI will not be liable to Customer's
     customers for any claim, liability or expense asserted by those
      customers in connection with Customer's sale or delivery of such
           service(s), including the unauthorized conversion of a customer's PIC
        designation to Customer's CIC. Customer and Members will indemnify
      and hold MCI harmless from any actions, claims, suits or damages
         arising out of a Member's violation or alleged violation of any FCC
           or other applicable law or state regulation, and Customer and Members
        will pay all attorney fees and costs incurred by MCI in connection
with such actions, claims, suits or damages.              

     (b)   Without limitation, if a Member fails to abide by the requirements in
Paragraph 19(a) above or violates any FCC or other applicable law or  
 regulation pertaining to the sale or delivery of Customer's service(s),
   such failure will be regarded as a material breach of this Agreement, and
MCI may terminate all or

   a portion of the service to such Member under this Agreement by providing
such Member fifteen (15) business days written notice of such material
breach.                                                               

(c)    Customer agrees that MCI may use an appropriate internal MCI   
database to determine Working Telephone Number ("WTN") historical data
    regarding MCI and non-MCI PICs, and Customer understands that such systems
are not error free. MCI will not be liable to Customer or Members for 
    errors made in determining WTN in reliance on information contained in the
internal MCI system.                                                  

   (d)   Customer agrees that if a Member's enduser makes a call using 1OXXX
or 1+ access utilizing Customer's CIC from an ANI which Member did not
 provide to MCI to enter into MCI's Billing and Order Entry systems, MCI
     will bill the call through the LEC at MCI Tariff or applicable state tariff
rates, and MCI's name will appear as the service provider on the LEC  
    invoice. Furthermore, Customer and Members agree that a Member's sales and
   marketing channels will only market 10XXX access as a dialing option from
  ANIs that the end-user had PIC'd to the Member's CIC, in areas where the
Member's CIC is pointed to MCI for termination.                       

 (e)   1)   Customer acknowledges that Customer has been informed by MCI
       that the CNS product does not support a multiple PIC for a single
          ANI. A "multiple PIC" is where: (i) the end user selects one carrier
for interLATA and a different carrier for intraLATA and/or
         international or (ii) the end user selects one carrier for operator
        service calls dialed with the 0+, 01+ or 00- dialing pattern and a
different carrier for 1+ long distance calls.             

          2)   Each Member will comply with Section 64.1150 of the FCC's Rules
      and Regulations, as well as other applicable laws or regulations
    pertaining to letter of agency requirements for a primary long
          distance carrier change. Each Member represents that during the term
          of this Agreement such Member will not submit any ANI for CNS unless
          Member has been selected as the carrier for interLATA, intraLATA and
     international traffic FOR ALL TRAFFIC TYPES for the ANI. Member
    understands that all ANIs submitted to MCI for Carrier Network
     Services will carry all traffic for such ANI (including but not
        limited to interLATA, intraLATA, international, interstate, 1+ and
   operator assisted) except for 10XXX calls directed to another
        carrier's CIC. ANIs with multiple PICs submitted by Members to MCI
for CNS will be deemed an unauthorized use of MCI's CNS.  

       3)   If a Member submits an ANI(s) with a multiple PIC to MCI for
           CNS, Member will be fully liable to MCI and all third parties for any
           claims, liability or expenses, including but not limited to fines and
    penalties, arising out of Member's submission of an ANI with a
      multiple PIC. MCI will not be liable to Customer, Members or any
        third party for any damage or loss due to a Member's submission of
      ANIs with multiple PICs. MCI will have no liability to Customer,
          Members or any third party for revenue that may have been earned but
   for MCI's inability to support multiple PIC for a single ANI.

        4)   Members will indemnify MCI, MCI's affiliated companies, MCI's
           and MCI's affiliated companies' their respective officers, directors,
      employees, agents or subcontractors, and will hold them harmless
      against all costs, expenses, liabilities, loses, damages, suits,
           fines, penalties, claims and demands of every kind or nature asserted
          by or on behalf of any person or entity arising out of or related to
           Member's submission of ANI(s) for CNS. Member will pay MCI reasonable
    attorney fees and costs, including allocable costs of in house
counsel, incurred in enforcing this Agreement.            

(f)   Members will receive CNS Feature Services (Call Detail Records, 
     Carrier Direct, and RELI) pursuant to the terms and conditions set forth in
Exhibit B of this Agreement.

   (a)   Members will provide MCI prior written notice on each occasion that
 Member subscribes to CNS at a detention facility. Notice to MCI will be
provided at:                                                          

MCI Telecommunications Corporation        
MCI Carrier Finance Services              
Attn:  Scott Rauschenberg                 
Six Concourse Parkway                     
Atlanta, GA 30328                         

 (b)   Member agrees after the Effective Date of this Agreement, but not
 more than once semi-annually, MCI may request, and Member will promptly
   provide to MCI in writing or in a machine readable format as specified by
    MCI, Member's records, data and invoices pertaining to Member's total long
   distance telecommunications usage for each Member detention facility end-
user for the most recent six (6) month period preceding the request.  

  (c)   MCI in MCI's sole discretion and consistent with Section B-7.04 of
MCI Tariff FCC No. 1 and in specific implementation of such Tariff    
   provision, may require Member, as a condition precedent to receipt of MCI
Carrier Network Service to detention facilities as defined above, to  
provide within ten (10) days of executing this Agreement, or any time 
    thereafter, a cash deposit or letter of credit in a form acceptable to MCI
 in an amount equal to [__________________________________________]. Any
executed letter of credit will be attached hereto and incorporated by 
     reference. Member will continuously renew any letter of credit as necessary
to keep such letter of credit in effect during the Service Term.      

    (d)   Notwithstanding any other provisions of the Tariff, each Member will
 remain responsible for payment of all charges for services furnished to
such Member, which responsibility is not changed by virtue of any use,
     misuse, or abuse of Member's service or Member-provided systems, equipment,
     facilities or service interconnected to Member's service, which use, misuse
   or abuse may be occasioned by third parties including without limitation,
Member's employees or other members of the public.                    

     (e)   Members will comply with applicable federal, state and local laws and
     regulations, including without limitation, laws and regulations relating to
     operator service as they pertain to detention facilities during the term of
this Agreement.                                                       

21.  Resale of MCI Services.                                                    

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

(b)   Customer agrees that Customer and each Member will obtain and   
  maintain any and all approvals to resell MCI Services 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 obtain or maintain the appropriate
           approvals, MCI will not be liable for any delay or failure to provide
MCI Services.                                             

        (c) Each Member will have sole responsibility for interacting with
        Member's customers in all matters pertaining to service, including
           the placing and handling of service orders, service installation, PIC
   provisioning, operation and termination, dispute handling and
       resolution, and billing and collection matters. MCI will incur no
   obligation, nor will MCI be deemed to have any obligation, to
        interact with Member's customers for any reason or purpose. Member
 will cooperate with MCI as necessary to address and resolve
       service-related issues and problems and will impose upon Member's
        customers an obligation to cooperate with Member in addressing and
resolving service-related issues and problems.            

           (d) MCI, Customer, and the Members each understands and accepts that,
      as part of each party's normal business policy and practices and
       obligations under law, that each of them will engage in extensive
          marketing efforts in an attempt to sell their services to the public
      and that such efforts will result in active competition with the
          other party for the business of users who are customers or prospects
          of such other party. Accordingly, each party further understands and
          accepts that such competition is in all respects fair and proper and
     that no party (including Members) will complain, or be heard to
          complain, of business lost to the other party. Under no circumstance
  will any inference be derived that a party's entry into this
          Agreement means that such party will restrict its efforts to compete
        against the other party in any way. Notwithstanding the foregoing,
         MCI will not use confidential information obtained from Customer or
      Members pursuant to this Agreement in connection with the active
         marketing of MCI services to the customers of Customer or a Member.

         (e) Customer understands and accepts that no fiduciary relationship
          arises by virtue of this Agreement and that, accordingly, MCI incurs
   none of the obligations that arise in such relationship as an
          incident of MCI's fulfilling MCI's obligations under this Agreement.
        Further, Customer understands and accepts that MCI neither insures
       the profits for Customer nor guarantees the success of Customer's
       business as a result of Customer's receipt of services under this
Agreement.                                                

22.        Access Review                                                        

If an event or events should occur within the telecommunications industry which 
directly results in a change in access and/or egress charges across the         
telecommunications industry of [_______________] or more, Customer or MCI may,  
request that the parties negotiate in good faith towards a mutually satisfactory
amendment of this Agreement to reflect such change. If the parties are not able 
to reach mutually satisfactory agreement with respect to the terms of an        
amendment within thirty (30) days after such change in access/egress charges    
becomes effective, then either party may terminate this Agreement without       
further liability to the other party, effective thirty (30) days after receipt  
of prior written notice by the non-terminating party.                           

23.        Counterparts.                                                        

This Agreement may be executed by the parties in one or more counterparts, each 
of which shall constitute an original, and which together shall constitute one  
Agreement.                                                                      

24.        Entire Agreement; Amendments.                                        

This Agreement will be valid only if signed by Customer by September 17, 1997,  
and if subsequently accepted by MCI. This Agreement shall be effective with     
respect to each Member after execution hereof by such Member, as described in   
Paragraph 8(a). Any and all prior or contemporaneous offers, representations and
understandings made to Customer or any Member, whether written or oral, are     
hereby superseded. This Agreement shall supersede the Carrier Agreement between 
MCI and Customer, signed by MCI on November 11, 1995, as heretofore amended.    
This Agreement shall not supersede or otherwise affect any service agreement    
which may currently be in effect between MCI and any Member. Exclusive of any   
Tariff or state tariff modifications initiated by MCI, once this Agreement has  
been executed, any amendments hereto must be made in writing and signed by both 
parties.

for at least the previous ninety (90) days) that Customer converts to MCI. For  
dedicated MCI Carrier Network Service the discount shall be based on the number 
of non-MCI DALs that Customer converts to MCI. Each month MCI will calculate the
overall cumulative total of non-MCI ANIs, WTNs or DALs converted to MCI and then
apply a discount to Customer's usage as follows:                                

Cumulative Percentage            Percentage of

such instance, Customer will pay the CNS domestic non-dedicated         
interstate outbound rates in Paragraph 1(a) and the non-dedicated       
intrastate rates in Paragraph 1(a).

Part A of the Tariff. These rates will apply only to circuits that are
     wholly-owned and operated end-to-end by MCI and the rates will not apply to

    circuits where MCI leases all or a portion of the DS-0, TDS 1.5, or TDS-45
 facilities, MCI may elect to provide a rate different than the rates in

4)   The provisioning of domestic TDS-45 Service is based upon service
     availability, as determined by MCI. The availability of domestic interstate
  TDS-45 Service is limited and MCI does not guarantee the provisioning of
    such service. Customer's ability to comply with the Monthly Commitment set
forth in Paragraph 2, will not be contingent upon the provisioning of 
domestic interstate TDS-45 Service.                                   

     5)   MCI will waive the M13 multiplex charges as such charges are described

  exceeds [________________] miles, MCI will waive Echo control charges on
such circuit.

I. CALL DETAIL RECORDS                                                        

Customer may receive call detail record ("CDR(s)") information daily through    
MCI's Call Window application and monthly through magnetic tapes. Weekly        
magnetic tapes is only available for Carrier Network Services Feature Card and  
network MCI conferencing.                                                       

A.         Daily CDRs. Daily CDRs are only available for outbound and toll free 
usage through the MCI Call Window Software, which resides on the MCI Service-   
View platform ("Call Window"). Call Window provides electronic access to daily  
CDR's. Daily CDR's will not be delivered via magnetic tape. The daily CDRs will 
be unedited by MCI's billing system and not audited by MCI's billing center to  
ensure timeliness of delivery. MCI will not be liable to Customer for any errors
or inaccuracies contained in the daily CDRs.                                    

1.  Daily CDRs are prepared as follows:                   

                     (a) An extract is taken of calls from MCI's call processing
  system prior to monthly invoice preparation and MCI will use
         reasonable efforts to have CDR's available to Customer two (2) days
after traffic is created..                                

                   (b) Files will be received by 12:00 p.m. Eastern Standard
Time, seven (7) days per week.                            

               (c) Two (2) communications access options to the Call
        Window server will be available for selection by Customer based on
          Customers predicated volume. Any and all expenses incurred to set up
           any dedicated line, hardware, software or other equipment that may be
required for data delivery shall be paid by the Customer. 

           2.        MCI does not assume responsibility for failures in delivery
    of CDR data which are caused by Customers billing and customer
          premise equipment. MCI will store files for up to fourteen (14) days
          in case a retransmission is requested, after which all files will be
purged.                                                   

           3.        Due to Error Suspense, as defined in paragraph B,2, not all
       calls will necessarily appear on the file specific to their date;
        calls may actually appear on a later file but the call will retain
the original date.                                        

          4.        Customer understands that daily CDR delivery is subject to
the following:                                            

                     (a) The record format will be identical to monthly magnetic
     tape except in ASCII rather than EBCDIC, and will be subject to
quarterly changes.                                        

                    (b) Daily CDRs will not always correspond with the monthly
file for the following reasons:                           

                  (i) records do not complete the full billing process and
               may get dropped as "unbillable" when the full billing
process is completed.                 

                 (ii) Error Suspense, as defined in paragraph B,2, could
                result in calls from previous dates being delivered in
         daily files. Normal Error Suspense accounts for
          approximately one percent (1%) of total traffic.

              (iii) calls can be recycled for ninety (90) days for
                domestic traffic and one hundred twenty (120) days for
                 international traffic until they are either invoiced or
 dropped in the invoice editing process.

                    (c) Call traffic can experience up to a two (2) week delay
         prior to appearing in the daily file process. This only occurs when
 ANI's added to a new account or Corporate Id which has been
       established within two weeks of when the ANI was tied to this new
account via MCI's order entry system.                     

                     (d) File creation is time driven (i.e., data is distributed
       at approximately the same time each day regardless of whether all
      files have been received from all data centers). Therefore, some
        files on given days could be incomplete with the remainder of data
          received on the following day's file. The file header shall indicate
           if all data was obtained from each of the three (3) MCI data centers.

                   (e) MCI shall have no obligation to research or track any
           discrepancies between the daily and monthly files. Customer shall pay
      pursuant to the monthly invoice, regardless of any discrepancies
between the monthly invoice and the daily files.          

      5. If Customer elects to receive Daily CDRs through the MCI Call
Window software application, Customer shall pay a one-time
 installation fee of Two Hundred Dollars ($200) for each MCI
ServiceView workstation.                                  

           6. CDR's for Carrier Operator Services are available to Customer on a
           next day basis. Customer assumes responsibility for pulling the CDR's
          from the Carrier Operator Services Bulletin Board. Records will only
        be posted to the bulletin board for ten (10) days from the date of
the call.                                                 

B.         Magnetic Tapes. The magnetic tapes shall be provided to Customer in  
MCI format and at applicable Tariff and state tariff rates and in accordance    
with the following:                                                             

       1. The CDR's from MCI on the weekly magnetic tape for MCI Feature
        Card and networkMCI Conferencing will be in the same record layout
format as the MCI monthly billing magnetic tape.          

          2. The weekly magnetic tape service is a value-added product and MCI
     shall have no obligation to research or track any discrepancies
           between monthly magnetic tape and the weekly call detail records (but
MCI may elect to do so, in its sole discretion).          

    3. MCI will use the monthly magnetic tape to invoice Customer.
       Customer is responsible for paying the monthly invoice in full in
accordance with the terms specified in this Agreement.    

     4. MCI makes no guarantee that such tape is compatible with any
         billing systems Customer may choose to use. Further, MCI assumes no
         obligation to conform the magnetic tape format to become compatible
      with any billing system of Customer or Customer's billing agent.

C.         Limitation of Liability. MCI's total liability to Customer arising   
from its provisioning of CDRs under this Exhibit B shall be limited to the      
lesser of (a) Customer's proven direct damages or (b) the total amount paid by  
Customer to MCI for CDR services during the one (1) month period prior to the   
event giving rise to the cause of action. The foregoing limitation applies to   
all causes of actions and claims, including without limitation breach of        
contract, breach of warranty, negligence, strict liability, misrepresentation   
and other torts. Further, no cause of action which arose more than six (6)      
months prior to the institution of a legal proceeding alleging such cause of    
action may be asserted by either party against the other.

II.       MCI CARRIER DIRECT                                                  

STANDARD CONDITIONS OF SERVICE (April 23, 1997)                                 

MCI Carrier Direct ("Carrier Direct") is a client - server software application 
on MCI's ServiceView ("ServiceView") platform, for sending order entry files    
directly to MCI's server application, providing remote access to ANI            
provisioning and ANI status reports for MCI Carrier Network Services ("CNS").   
Carrier Direct shall be implemented in accordance with the standard terms of    
service prescribed by MCI from time to time, the terms of service and software  
license provisions applicable to use of MCI's ServiceView platform, the         
respective Conditions of Service set forth herein, and the provisions of the    
carrier agreement between MCI and Customer pursuant to which CNS is provided    
("Carrier Agreement"). Any use of Carrier Direct by Customer shall signify      
Customer's acceptance of such terms and provisions, as may then be in effect.   

A.         Customer's Responsibilities.                                         

      1. Customer shall, at its expense, be responsible for obtaining,
installing, operating and maintaining all necessary terminal equipment and      
software in accordance with the equipment and software specifications and       
requirements prescribed by MCI for use of Carrier Direct. MCI is not responsible
for the installation, maintenance, compatibility or performance of any equipment
or software not provided by MCI.                                                

         2. Customer shall use Carrier Direct to input all data pertinent to
an ANI, or upload such data files in the format prescribed by Carrier Direct.   
Customer shall have the right to use Carrier Direct only to obtain, view, alter,
supplement, or change data, reports, records or other information directly      
relating to Customer's use of MCI CNS Service and ANIs PICed to Customer.       
Customer shall be fully responsible for the content and accuracy of all data    
submitted through Carrier Direct.                                               

       3. Customer shall be responsible for regularly monitoring Carrier
Direct for reports, notices and other information applicable to Customer,       
Customer's ANIs and Customer's use of CNS. Customer shall be responsible for    
archiving Customer's data, reports, notices and records. Customer shall be      
charged with receipt and notice of all data, reports, notices and other         
information posted to Customer's attention or otherwise available to Customer on
Carrier Direct, from the date of posting or availability.                       

         4. Carrier Direct is available for Customer's internal use only and
shall not be distributed to Customer's agents, customers, consultants or any    
other entity who is not a party to the Carrier Agreement. Customer shall be     
solely responsible for protection of its transmission facilities, premises      
equipment, its data entered on the Carrier Direct system, and its ID(s),        
password(s), user names and the like, from all unauthorized access or use.      
Customer shall comply with all security procedures and standards prescribed by  
MCI with respect to Customer's use of Carrier Direct.                           

           5. Customer shall not use Carrier Direct or permit any use of Carrier
Direct which is illegal, unlawful, or harassing, or which infringes intellectual
property rights of MCI or any third person, or which otherwise constitutes      
network abuse.                                                                  

          6. Customer shall indemnify MCI and its affiliated companies and its
or their respective officers, directors, employees, agents or subcontractors and
hold them harmless from all costs, expenses, liabilities, losses, damages,      
suits, fines, penalties, claims, and demands of every kind or nature asserted by
or on behalf of any person or entity arising out of or related to (i) the misuse
or unauthorized use of Carrier Direct by Customer or any person or entity,      
whether authorized by Customer or otherwise, using Carrier Direct through       
Customer's facilities or Customer's accounts; or (ii) the data, information,    
files or transmissions submitted, obtained or initiated by Customer to or from  
Carrier Direct. Customer shall pay MCI reasonable attorney fees and costs,      
including allocable costs of in house counsel, incurred by MCI in enforcing this
Agreement.

B.         Limitations on Service.                                              

          1. MCI may suspend or terminate Customer's access to Carrier Direct,
upon thirty (30) days prior written notice, if Customer's use of Carrier Direct 
or the Carrier Direct software is in violation of these Conditions of Service,  
the Carrier Agreement, the ServiceView Software License Agreement.              
Notwithstanding the foregoing, MCI may immediately suspend or terminate         
Customer's access to Carrier Direct, without prior notice, if: (a) the Carrier  
Agreement is terminated for any reason; (b) if necessary, in the sole           
determination of MCI in order to prevent damage to or degradation of MCI's      
network and/or database integrity, or to protect the interests of MCI and its   
customers from immediate harm; or (c) if necessary to comply with any law,      
regulation, court order, or other governmental request order which requires     
immediate action, or otherwise to protect MCI from legal liability.             

          2. CARRIER DIRECT IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS
WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
WARRANTIES OF TITLE, NONINFRINGEMENT OR IMPLIED WARRANTIES OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE. NO ADVICE OR INFORMATION GIVEN BY MCI'S       
EMPLOYEES, AGENTS OR CONTRACTORS SHALL CREATE A WARRANTY. CUSTOMER ASSUMES TOTAL
RESPONSIBILITY FOR CUSTOMER'S USE OF CARRIER DIRECT. MCI MAKES NO EXPRESS OR    
IMPLIED WARRANTIES, REPRESENTATIONS OR ENDORSEMENTS REGARDING ANY INFORMATION   
PROVIDED THROUGH CARRIER DIRECT.                                                

       3. MCI shall operate and maintain Carrier Direct, contingent upon
MCI's ability to maintain necessary licenses or permissions and MCI's network   
capacity and connection availability. MCI has no obligation to monitor Carrier  
Direct; however, MCI may monitor Carrier Direct and disclose to lawful          
authorities information gained from such monitoring in order to satisfy any law,
regulation or other governmental request, to operate Carrier Direct properly, or
to protect MCI or its customers. MCI reserves the right to refuse to post or to 
remove any information, in whole or in part, that, in MCI's sole discretion, is 
unacceptable, undesirable, or in violation of these Conditions of Service.      

         4. Until MCI notifies Customer of MCI's ability to support multiple
PICs, MCI will not accept any ANI submitted through Carrier Direct for MCI CNS  
unless Customer has been selected as the carrier for interLATA, intraLATA and   
international traffic for all call types for such ANI.                          

      5. While Customer is utilizing Carrier Direct, provisions of the
Carrier Agreement relating to other methods or procedures for provisioning of   
ANIs or ANI management and reporting shall be inapplicable. If MCI terminates   
Carrier Direct, MCI shall satisfy its obligations under the Carrier Agreement   
with respect to ANI provisioning and management by the ANI provisioning and     
management procedures in effect prior to the availability of Carrier Direct or  
by other means reasonably acceptable to Customer.                               

C.        Limitation of Liability.                                            

           1. MCI's total liability to Customer arising from its provisioning of
Carrier Direct to Customer shall be limited to the lesser of (a) Customer's     
proven direct damages or (b) $5,000. The foregoing limitation applies to all    
causes of actions and claims, including without limitation breach of contract,  
breach of warranty, negligence, strict liability, misrepresentation and torts.  
Except with respect to claims arising directly as a result of MCI's provisioning
of Carrier Direct, such limitation of liability is not exclusive of remedies    
which might otherwise be available to Customer under the Carrier Agreement.     

     2. UNDER NO CIRCUMSTANCES SHALL MCI BE LIABLE FOR ANY INDIRECT,
INCIDENTAL, SPECIAL, PUNITIVE OR CONSEQUENTIAL DAMAGES, UNDER ANY THEORY OF     
TORT, CONTRACT, STRICT LIABILITY, NEGLIGENCE OR OTHER LEGAL THEORIES, EVEN IF   
MCI HAD BEEN ADVISED, KNEW OR SHOULD HAVE KNOWN OF THE POSSIBILITY OF SUCH      
DAMAGES, THAT RESULT FROM CUSTOMER'S USE OF OR INABILITY TO ACCESS ANY PART OF  
CARRIER DIRECT OR CUSTOMER'S RELIANCE ON OR USE OF INFORMATION PROVIDED ON OR   
THROUGH CARRIER DIRECT, OR THAT RESULT FROM MISTAKES, OMISSIONS, INTERRUPTIONS, 
DELETION OF FILES, ERRORS, DEFECTS,

DELAYS IN OPERATION, OR TRANSMISSION, OR ANY FAILURE OF PERFORMANCE OF CARRIER  
DIRECT.                                                                         

SERVICEVIEW SOFTWARE LICENSE AGREEMENT -- CONFIDENTIALITY ADDENDUM              

 1. Confidential Information. By virtue of MCI's license and
------------------------                            
Customer's use of the ServiceView Software, including Carrier Direct, the       
parties may have access to, or exchange, information that is confidential to one
another. As used in this Addendum, the term "Confidential Information" shall    
mean only such information of the other party that may be reasonably understood 
from legends, the nature of such information itself and/or the circumstances of 
such information's disclosure, to be confidential and/or proprietary to the     
other party or to third parties to which the other party owes a duty of         
non-disclosure. MCI and Customer agree that the ServiceView application,        
including Carrier Direct, any documentation provided by MCI in connection       
therewith, and any data contained in MCI's databases accessed by the ServiceView
application shall be deemed the Confidential Information of MCI for purposes of,
and to be treated by Customer in conformity with, the requirements of this      
Addendum. This Addendum conveys no rights to a party to obtain, view or use any 
information of the other party or any third party unless authorized under the   
terms of the ServiceView Software License Agreement, the Carrier Agreement, or  
the Standard Conditions of Service for Carrier Direct.                          

2. Obligations. Each of the Parties agrees that as to any 
-----------                                         
Confidential Information disclosed by one Party ("Discloser") to the other Party
("Recipient") hereunder:                                                        

             (a)       to use such Confidential Information only in connection
with the services provided as part of the Carrier Agreement between the parties,
or as otherwise expressly permitted by the Discloser;                           

             (b)       not to make copies of any such Confidential Information
or any part thereof except to the extent expressly permitted by the Carrier     
Agreement or by the Discloser;                                                  

              (c)       not to disclose any such Confidential Information to any
third party, using the same degree of care used to protect Recipients own       
confidential or proprietary information of like importance, but in any case     
using no less than a reasonable degree of care; provided, however, without      
intending to alter any right or limitation of disclosure from that expressly    
authorized under the terms of the ServiceView License Agreement, that Recipient 
may disclose Confidential Information received hereunder to its employees who   
have a need to know to perform or exercise rights under the Carrier Agreement,  
and who are bound to protect the received Confidential Information from         
unauthorized use and disclosure under the terms of a written agreement          
(including without limitation a pre-existing written agreement); and            

            (d)       to return such Confidential Information and any copies
thereof upon any expiration or earlier termination of the Carrier Agreement, or 
upon Customer's discontinuation of use of the ServiceView Software.             

           3. Exceptions. The restrictions set forth in this Addendum on the use
----------                                          
and disclosure of Confidential Information shall not apply to information that: 
(a) was publicly known at the time of Discloser's communication thereof to      
Recipient or through no fault of Recipient subsequent to the time of Discloser's
communication thereof to Recipient; (b) is in Recipient's possession free of any
obligation of confidentiality at the time of Discloser's communication thereof  
to Recipient; (c) is developed by Recipient independently of and without use of 
any of Discloser's Confidential Information or other information that Discloser 
disclosed in confidence to any third party; (d) is rightfully obtained by       
Recipient without restriction from third parties authorized to make such        
disclosure; or (e) is identified by Discloser in writing as no longer           
proprietary or confidential.                                                    

         4. Disclosure Pursuant to Legal Requirement. In the event Recipient
----------------------------------------            
is required by law, regulation or court order to disclose any of Discloser's    
Confidential Information, Recipient will promptly notify Discloser in writing   
prior to making any such disclosure in order to facilitate Discloser seeking a  
protective order or other appropriate remedy from the proper authority.         
Recipient agrees to cooperate with Discloser in seeking such order or other     
remedy. Recipient further agrees that if Discloser is not successful in         
precluding the requesting legal body from requiring the disclosure of the       
Confidential Information, it will furnish only that portion of the Confidential 
Information which is

legally required and will exercise all reasonable efforts to obtain reliable    
assurances that confidential treatment will be accorded the Confidential        
Information.                                                                    

        5. Proprietary Notices. Each Party shall reproduce and maintain on
-------------------                                 
any copies of the other Party's Confidential Information received hereunder,    
including without limitation the ServiceView Software, including Carrier Direct,
and any related documentation, such proprietary legends or notices (whether of  
the Party providing the Confidential Information or of a third party) as are    
contained in or on the original.                                                

           6. Term. The rights and obligations arising under this Addendum shall
----

ATTACHMENT TO EXHIBIT G 

MCI FEATURE CARD FRAUD DETECTION PROCEDURES 
------------------------------------------- 

All calling card calls will be validated by MCI to permit only those calls      
authorized or facilitated by Customer or legitimate card holders. MCI will, at  
the direction of Customer, preclude all calls utilizing expired or terminated   
calling card numbers compared against an authorized list provided by Customer   
and will be responsible for all fraudulent use, unauthorized use, misuse, or    
abuse of calling cards occurring after MCI receives actual notice of the        
expiration or termination of a calling card or receives specifically detailed   
written notification concerning any card which has been lost, stolen,           
compromised or which Customer has reason to believe is or may be used           
fraudulently. MCI will deactivate a calling card within four (4) hours of       
receipt by MCI's Consumer Markets Fraud Detection of a request by Customer.     

In addition, all calling card calls will be monitored by MCI for fraudulent use,
unauthorized use, misuse or abuse on a twenty four (24) hour a day, seven (7)   
days a week basis. MCI shall establish fraud prevention, detection and          
minimization procedures so that fraudulent use arising from lost or stolen      
calling cards and potential disruption to authorized card holders will be       
minimized.                                                                      

MCI will not hold the Customer responsible for "service fraud" associated with  
the unauthorized use of an MCI calling card. "Service fraud" can best be        
described as unauthorized use of an MCI calling card following the involuntary  
theft or loss of a card which was not intentionally facilitated or impliedly    
authorized by Customer or an authorized user. "Service fraud" often follows the 
theft of a wallet, purse or briefcase, or sometimes is the result of "shoulder  
surfing" (thieves observing/recording authorization codes) which occurs at      
payphones located in airports, bus terminals, train stations and the like. MCI  
shall not be responsible for losses caused by fraudulent information submitted  
by a card holder in subscribing for calling card services or for usage which was
intentionally facilitated or impliedly authorized by an authorized user.        

In the event that MCI is unable to contact Customer of suspected abuse of the   
calling card, in order to minimize potential abuse, MCI will deactivate any     
calling card which has exceeded established fraud detection parameters or which 
MCI has reason to believe is or may be used fraudulently.

CONFIDENTIAL TREATMENT. THE OMITTED PORTIONS HAVE BEEN FILED SEPARATELY WITH THE

MCI CARRIER OPERATOR SERVICES 

Customer is interested in buying MCI Carrier Operator Services for resale and   
MCI is interested in providing such services to Customer. In order to accomplish
those purposes the parties hereby agree as follows:                             

1.   Operator Services.                                                         
-----------------                                                     

  (a) Carrier Operator Services for Carrier Network Services Customers may
not be supported by MCI in all LEC end offices due to excessive       
     requirements for CIC loading and administrative demands by such LEC, in the
determination of MCI.                                                 

   (b) "Operator Service Calls" mean long distance calls dialed with the 0+,
  01+ or 00- dialing pattern (and excluding calls dialed with the 950-XXXX
and 800 dialing patterns).                                            

     (c) Customer shall not use any service mark or trademark of MCI or refer to
 MCI in connection with any service provided hereunder without the prior
written approval of MCI.                                              

(d) Call Originating Identification Information. MCI must receive     
-------------------------------------------                   
  electronic call origination identification ANI information for each call
carried hereunder. If the Originating Site uses Feature Group D local 
     access service, the required call origination identification information is
  automatically supplied by the local exchange company. If the Originating
   Site uses a type of local access service other than Feature Group D local
access service, the Originating Site shall cause electronic call      
    origination identification information (in a form acceptable to MCI) to be
supplied to MCI at the initiation of each call.                       

  (e) Emergency Calls. Each Originating Site shall configure its system so
---------------                                               
 that 911 emergency calls, where available, and similar emergency calls,
 will be automatically routed to the appropriate party or clearing house
without the intervention of MCI. Emergency calls which do reach a MCI 
operator shall be handled in accordance with MCI standard operating   
   procedures. MCI makes no representation or warranty as to the handling of
9l1 or other emergency calls.                                         

(f)  Payphones.                                                       
---------                                                   

(1)  Payphone lines must be classed as "07" COCOT.          

    (2)  All payphones must have Billed Number Screening ("BNS"), if
      available. If BNS is not available, the Customer will be
    responsible for calls billed to any lines without BNS.

          (3)  Unless otherwise permitted by law, all 0- calls must be passed to
the Local Exchange Carrier ("LEC").               

   (4)  Payphones must not block 950-XXXX or l-800-XXX-XXXX calls.

         (5)  All payphones must have "011" blocking at the central office, if
          available. If international blocking is not available, or if
              Customer chooses not to block "011" calls, then Customer assumes
responsibility for any international fraud.       

        (6)  For Premises Telephones located in condominiums, Customer shall
               be liable for all charges attributable to the failure of Customer
      to secure screening which prevents 1+ 1OXXX domestic and
             international dialing and which indicates to operators that the
              telephone is restricted to prohibit billing to the original ANI.
