1.    PRIOR AGREEMENT: Notwithstanding anything to the contrary contained in
      Section 24 of the Telecommunications Services Agreement (the "TSA"), the

      Telecommunications Services Agreement dated November 15, 1994, and more
      particularly described as TSA#NTC-941101 (the "Prior Agreement"). The
      parties agree that as of the Effective Date described in Section 2 below,
      (i) the Prior Agreement will be canceled in its entirety and of no further
      force or effect with the exception of certain accrued obligations arising
      under the Prior Agreement such as the payment of money or the application
      of credits arising prior to the Effective Date, and provisions intended to
      survive termination, such as limitation of liability, indemnification and
      confidentiality, and (ii) all Services currently being provided under the
      Prior Agreement will be provisioned and maintained by WorldCom taking
      into account the terms and conditions of this Agreement (including the
      rates set forth in the Rate Schedule attached herewith).

      "Effective Date") and shall continue through and include October 31, 2001
      (the "Service Term"), subject to extension as provided in Subsection 3(B)
      below; provided, however, in no event will this Agreement be extended past
      October 31, 2003. Upon expiration of the Service Term, the Switched

3.    CUSTOMER'S MINIMUM MONTHLY REVENUE COMMITMENT/DEFICIENCY CHARGE:

      (A) Commencing with the November, 1998, billing period (i.e., December,
      1998 invoice) and continuing through the end of the Service Term, Customer
      agrees to maintain, on a take-or-pay basis, Monthly Revenue (as defined in
      the applicable Rate Schedule) of at least the amounts shown below
      (collectively, "Customer's Minimum Revenue Commitment") in the respective
      periods shown (collectively, the "Commitment Period"), subject to
      modification as described in Section 4 below.

                                                     Minimum Monthly
      Period                                       Revenue Commitment
      ------                                       ------------------
      11/1/98 (12/1/98 invoice) through 4/30/99             [*]
      5/1/99 (6/1/99 invoice) through 10/31/99              [*]
      11/1/99 (12/1/99 invoice) through 10/31/00            [*]
      11/1/00 (12/1/00 invoice) through 10/31/01            [*]

      (B) In the event the Service Term is extended as described in Subsection
      4(C) below, Customer's Minimum Revenue Commitment during the extension
      period(s) will be as follows for the periods indicated.

                                                     Minimum Monthly
      Period                                       Revenue Commitment
      ------                                       ------------------
      11/1/99 (12/1/01 invoice) through 10/31/02            [*]
      11/1/00 (12/1/02 invoice) through 10/31/03            [*]

      (C) In the event Customer does not maintain Customer's applicable Minimum
      Revenue Commitment in any month shown above, then for those month(s) only,
      Customer will pay WorldCom the difference between Customers applicable
      Minimum Revenue Commitment and Customer's actual Monthly Revenue (as
      described in the applicable Rate Schedule) for such month (collectively,
      the "Deficiency Charge"). The Deficiency Charge will be due at the same
      time payment is due for Service provided to Customer, or immediately in an
      amount equal to Customer's applicable Minimum Revenue Commitment(s) for
      the unexpired portion of the Service Term, if WorldCom terminates this
      Agreement based on Customer's default.

4.    CUSTOMER'S AGGREGATE MINIMUM REVENUE COMMITMENT:

      (A) In addition to Customer's Minimum Monthly Revenue Commitments
      described in Section 3 above, commencing with the Effective Date and
      continuing through the end of the Service Term (subject to extension as
      provided herein) Customer agrees to maintain Monthly Revenue which totals
      in the aggregate of at least $250,000,000 (which amount may be increased
      as described in Subsection (B) below) ("Customer's Aggregate Commitment").
      In order to achieve Customer's Aggregate Commitment, Customer agrees to
      maintain cumulative Monthly Revenue of at least the amounts shown below
      (collectively, the "Target Amount") in the respective yearly periods
      indicated (the "Target Period"):


                                  Page 2 of 5


      Period                                       Target Amount
      ------                                       -------------
      November, 1998 - October, 1999 (Year 1)           [*]
      November, 1999 - October, 2000 (Year 2)           [*]
      November, 2000 - October, 2001 (Year 3)           [*]

      IF APPLICABLE AS DETERMINED UNDER SUBSECTION (C) BELOW:

      November, 2001 - October, 2002 (Year 4)      To be Determined
      November, 2002 - October, 2003 (Year 5)      To be Determined

      (B) In the event Customer's actual cumulative Monthly Revenue in any
      Target Period (including any Deficiency Charges described in Subsection
      3(C) above actually paid by Customer during such Target Period) is greater
      than the applicable Target Amount for such Target Period, any excess
      amount will be deducted from the Target Amount for such the immediately
      following Target Period.

      (C) In the event Customer's actual cumulative Monthly Revenue in any
      Target Period (including any Deficiency Charges described in Subsection
      3(C) above actually paid by Customer during such Target Period) is less
      than the applicable Target Amount for such Target Period (hereinafter
      referred to as a "Shortfall Amount"), the Shortfall Amount will first be
      increased by the applicable percentage shown below and then added to the
      Target Amount for the immediately following Target Period. Further,
      Customer's Aggregate Commitment will be increased by an amount equal to
      the Shortfall Amount times the percentage shown ("Customer's Modified
      Aggregate Commitment"). If necessary, the Service Term will be extended
      beyond Year 3 but in no event will the extension period go beyond October
      31, 2003.

               Year      Percent
               ----      -------
                1           [*]
                2           [*]
                3           [*]
                4           [*]

            Example: Assume Customer's actual Monthly Revenue in Year 1 is [*].
            The Target Amount for Year 2 will be [*][[*]+([*]x[*])] and
            Customer's Aggregate Commitment will be [*]([*]+[*]x[*]).

      (D) As soon as Customer's aggregate Monthly Revenue since November 1,
      1998, equals at least Customer's Aggregate Commitment (or Customer's
      Modified Aggregate Commitment, if applicable), either Customer or WorldCom
      may terminate this Agreement upon at least ninety (90) days' prior written
      notice.

5.    REQUIREMENTS AGREEMENT: In consideration of the rates set forth in the
      Rate Schedule, a reduction in Customer's commitments under the Prior
      Agreement, and other good and valuable consideration, the receipt and
      sufficiency of which are hereby acknowledged, during the Service Term
      Customer agrees to purchase one hundred percent (100%) of its
      telecommunications services requirements from SWITCHED


                                  Page 3 of 5


      ACCESS Service (1+ and Toll Free) (which services are described in this
      Agreement) from WorldCom under the terms and conditions set forth in this
      Agreement ("Customer's Requirements Obligation"). Upon request from
      WorldCom, Customer agrees to provide WorldCom reasonable documentation
      evidencing Customer's compliance with this Section 5 and if requested by
      WorldCom, agrees to allow WorldCom or its representatives to audit
      Customer's books and records as may be necessary solely to ensure
      Customer's compliance with Customer's Requirements Obligation. In the
      event Customer is in breach of this Agreement, in addition to WorldCom's
      other rights and remedies described in this Agreement, notwithstanding
      anything to the contrary contained in the Agreement, WorldCom shall have
      the right to immediately increase Customer's SWITCHED ACCESS Service rates
      set forth in the Rate Schedule to [*]. Any increase as described herein
      will not affect Customer's Commitments set forth in Sections 3 and 4
      above.

6.    WAIVER OF DEFICIENCY CHARGES: Upon execution of this Agreement, in
      consideration of Customer's Requirements Obligation and other good and
      valuable consideration, the receipt and sufficiency of which are hereby
      acknowledged, WorldCom agrees to waive all deficiency charges which have
      been assessed Customer under the terms of the Prior Agreement up through
      and including October 31, 1998.

7.    QUARTERLY REVIEW OF RATES: Provided Customer is in substantial compliance
      with the terms of this Agreement, commencing February 1, 1999, and
      continuing on the first day of every fourth (4th) month thereafter (i.e.,
      June 1, October 1, February 1, etc.), WorldCom and Customer agree to
      review the rates hereunder and negotiate in good faith as to whether
      modifications are necessary in order to maintain reasonable parity between
      such rates and rates then made generally available by WorldCom to its
      other carrier customers for the same Services taking into account all of
      the terms associated with such rates. In connection with such review, the
      parties agree to review the relative state of parity between the
      then-current rates offered to Customer under the terms of this Agreement
      and the rates generally available in the wholesale marketplace for similar
      services and commitments. Provided, however, nothing contained in this
      Section 7 will obligate WorldCom to reduce Customer's rates under this
      Agreement or obligate or require WorldCom to adopt the same or similar
      rates or offer the same or similar products of third parties.

8.    CONDITIONAL OBLIGATIONS: The parties specifically acknowledge that the
      terms and conditions offered hereunder are contingent upon (i) Customer's
      compliance with the requirements set forth in that certain Forbearance
      Letter dated October 30, 1998 from Denis Richard, Customer's President and
      Chief Executive Officer Robert S. Vetera, Director of Credit for WorldCom,
      and (ii) WorldCom and Customer's reconciliation of all of Customer's
      accounts on or before March 15, 1999, which reconciliation must be
      satisfactory to WorldCom.

9.    PROMOTIONAL CREDIT: In consideration of Customer's Minimum Revenue
      Commitment (as described in Section 3 above) and other good and valuable
      consideration, the receipt and sufficiency of which are hereby
      acknowledged, WorldCom agrees to provide Customer a nine-month promotional
      pricing allowance (as


                                  Page 4 of 5


      described herein) based on the incremental growth of charges for
      Customer's Interstate SWITCHED ACCESS Service (1+ and Toll Free) within
      the 48 contiguous United States ("Promotional Traffic"). For purposes of
      this Section 9, the parties agree that the base amount (the "Base Amount")
      of charges for such Promotional Traffic will be determined by multiplying
      (x) Customer's minutes of Promotional Traffic shown on Customer's November
      1, 1998 invoice (i.e., Customer's October, 1998 Promotional Traffic) times
      (y)[*](hereinafter referred to as the "Base Amount"). WorldCom will then
      apply a discount (the "Promotional Credit") equal to [*] for every dollar
      charged Customer over the Base Amount for the Promotional Traffic, if any,
      for the nine (9) months commencing with Customer's December 1, 1998
      invoice (i.e., Customer's November, 1998 Promotional Traffic) and
      continuing through Customer's August 1, 1999 invoice (i.e., Customer's
      July, 1999 Promotional Traffic). Promotional Credits, if any, will be
      applied by WorldCom one month in arrears. For example, the first
      Promotional Credit, if any, based on Customer's December 1, 1998 invoice
      will be applied to Customer's January 1, 1998 invoice, and the Promotional
      Credit, if any, based on Customer's August 1, 1999 invoice will be applied
      to Customer's September 1, 1999 invoice.

      IN WITNESS WHEREOF, the parties have executed these Classic/TRANSCEND(TM)
Switched Services Program Enrollment Terms.
