                [LOGO OF CABLE & WIRELESS, INC. APPEARS HERE]
 
              GENERAL TERMS AND CONDITIONS FOR CARRIER AGREEMENTS

1.   Service to be Provided by CWI: CWI will provide the long-distance services
     -----------------------------
     set forth in the Order Information section of this Agreement (hereinafter
     collectively, "Services").

     The Carrier will access CWI's network via dedicated T-1 lines ("Access
     Lines") ordered from local exchange carriers or alternate access carriers
     (collectively, "Local Carriers") and paid for by the Carrier. If the
     Carrier orders an Access Line from a Local Carrier, the Carrier will pay
     the Local Carrier directly for the Access Line. If the Carrier requests CWI
     to order the Access Line and if permitted by the Local Carrier, CWI will
     order the Access Line on behalf of the Carrier and will have the Local
     Carrier bill the Carrier directly for the Access Line.

2.   Term: The term of this Agreement will start as of the date it is fully
     ----
     executed and it will continue thereinafter for the number of months after
     service is initiated set forth in the "Term" portion of the Order
     Information section of this Agreement ("Term").

3.   Rates and Taxes: The Carrier will pay any monthly, usage, and one-time
     ---------------
     charges set forth in the Dedicated Access Service Agreement, and the rates
     set forth or referenced in the Order Information section of this Agreement.
     Each call will be billed in 6-second increments and will be subject to a
     30-second minimum charge except that domestic outbound calls (both
     interstate and intrastate) will be subject to a 6-second minimum charge.
     The Carrier will pay any applicable federal, state, or local taxes,
     surcharges, or similar fees for the Services.

4.   Payment: CWI will provide monthly involves covering designated 30-day
     -------
     periods which will be due and payable within the "Payment Period" set forth
     in the Order Information section of this Agreement.

     If the Order Information section of this Agreement indicates that estimated
     payments are required, CWI will notify the Carrier on the last day of the
     "Estimated Usage Period," or if such day is not a business day, on the next
     business day, as to CWI's estimate of the charges incurred by the Carrier
     during such period. The Carrier will pay CWI such estimated amount
     ("Estimated Payment") no later than the "Estimated Payment Due Date". At 
     the end of a CWI monthly billing period, CWI will provide an invoice for
     the usage charges actually incurred that month less that month's Estimated
     Payment; provided, however, that if a minimum monthly payment obligation
     applies for that month and such minimum has not been met, then the invoice
     amount will be that month's minimum payment obligation less that month's
     Estimated Payment. The Carrier will pay the invoiced amount within the
     Payment Period.

     A late payment charge will be applied on balances that remain unpaid after
     the Payment Period in the amount of the lesser of (a) 1 1/2% per month of
     the amount of the late payment starting from the day following the Payment
     Period, or (b) maximum amount allowed under applicable law. The Carrier
     must pay all invoices when due; any questions which the Carrier may have
     concerning an invoice must be brought to CWI's attention within forty-five
     (45) days of the invoice date. The Carrier shall reimburse CWI for any
     expenses, including, without limitation, reasonable attorney's fees, CWI
     may incur in collecting amounts due hereunder.
     
     If so indicated in the Order Information section of this Agreement, all
     payments by the Carrier will be made via wire transfer (in immediately
     available funds) to Mellon Bank, 3 Mellon Bank Center, Room 153-2718,
     Pittsburgh, PA 15259-0001, ABA #0430-00261/Account#1705643.

5.   Financial Reports: If the Order Information section of this Agreement
     -----------------
     indicates that financial reports are required, within thirty (30) days
     after the end of each calendar quarter, the Carrier will provide CWI with a
     written report updating the Carrier's financial status ("Quarterly
     Report"), and within ninety (90) days after the end of each calendar year,
     the Carrier will provide CWI with an audited annual report. Each Quarterly
     Report will contain, as a minimum, an updated balance sheet and income
     statement. The Carrier represents and warrants that no Quarterly Report
     will contain any material misstatement or omission bearing on the Carrier's
     financial condition.

6.   Security Deposits: If the Order Information section of this Agreement
     -----------------
     indicates that security deposits are required, each required security
     deposit will be either in cash (paid by check or via wire transfer) or an
     irrevocable stand-by letter of credit in a form and from a financial
     institution reasonably acceptable to CWI. The "Initial Security Deposit"
     amount will be provided prior to the initiation of service. Thereafter, if
     requested in writing by CWI, the Carrier will add additional amounts to the
     Initial Security Deposit such that the total amount of security deposit
     being held by CWI at all times is at least equal to the "Continuing
     Security Deposit". The Carrier will provide any such required additional
     amounts within five (5) business days after receiving CWI's written
     request. CWI will refund or release, as applicable, any security deposit it
     is holding (plus, if the security deposit is in the form of cash, accrued
     interest at the applicable rate set by regulation of the state in which CWI
     invoices the Carrier, or if no such rate is set by regulation, CWI's then-
     prevailing interest rate for security deposit refunds) if the following
     conditions are met by the Carrier: (i) for the entire "Deposit Release
     Period", the Carrier pays CWI in full when each payment is due; and (ii)
     CWI determines that the Carrier's Quarterly Reports covering the Deposit
     Release Period indicate that the Carrier's financial condition has had no
     materially adverse change as compared to the equivalent period of time
     immediately prior to the start of the Deposit Release Period. If CWI does
     not refund or release the security deposit during the Term as set forth
     above, the security deposit will be refunded or released, as applicable, at
     the end of the Term.

7.   Minimum Payment Obligations: If the total amount of usage charges incurred
     ---------------------------
     by the Carrier in any month is less than the amount of the then-applicable
     minimum monthly payment obligation set forth in the Order Information
     section of this Agreement, then in addition to paying for its actual usage
     that month, the Carrier will pay (as an underutilization fee and not as a
     penalty) a shortfall charge equal to the difference between (i) the actual
     usage charges incurred that month, and (ii) the amount of the
     then-applicable minimum monthly payment obligation.

8.   Termination: Prior to the end of the Term, the Carrier may, for its
     -----------
     convenience, terminate this Agreement in its entirety by providing CWI with
     thirty (30) days' prior written notice. In such event, in addition to
     paying for all charges incurred through the date service is discontinued,
     including any applicable shortfall charges, the Carrier will pay (as a
     contract discontinuance fee and not as a penalty) a discontinuance charge
     equal to the sum of the minimum monthly payment obligations for each of the
     remaining months in the Term.

     If the Carrier fails to do any of the following when due and then does not
     cure such failure within three (3) business days after receiving notice
     thereof from CWI, CWI may, in addition to any other remedies available to
     it and without any further written notice to the Carrier, immediately
     terminate this Agreement in its entirety and discontinue providing
     Services: (i) make a payment in full; (ii) provide any required security
     deposit amount; or (iii) provide any required financial report.

9.   Additional Terms: This is a carrier-to-carrier agreement subject to (S)211
     ----------------
     of the Communications Act of 1934, as amended. The Carrier is responsible
     for and shall comply with any and all legal and regulatory requirements
     with respect to the Carrier's use and resale of the Services, including
     those of the Federal Communications Commission and state public utility
     commissions. The Services are governed by this Agreement and all Carrier
     obligations and CWI rights set forth in the "General Rules and Regulations"
     section of CWI's interstate tariff, as may be amended by CWI in accordance
     with applicable laws and regulations. The Carrier shall defend, indemnify
     and hold CWI harmless from and against all claims, demands, actions, causes
     of action, judgments, costs and reasonable attorneys' fees and expenses of
     any kind arising from or related to any use of the Service or otherwise
     arising under this Agreement. In no event shall CWI be liable for any loss
     of profits, or for any indirect, incidental, special, exemplary or
     consequential damages.

     This Agreement is effective as of the date of signature of the last party
     to sign and it is governed by and subject to the laws and the exclusive
