NOTES:
   If no rate is identified in the contract, the rate for the specific service
   or function will be as set forth in applicable BellSouth tariff or as
   negotiated by

   1  In states where a specific NRC for customer transfer, feature additions
      and changes is not stated, the applicable NRC from the appropriate tariff
      applies.

   2  Transmission/usage charges associated with POTS circuit switched usage
      will also apply to circuit switched voice and/or circuit switched data
      transmission by B-Channels associated with 2-wire ISDN ports.

   3  Access to B Channel or D Channel Packet capabilities will be available
      only through BFR/New Business Request Process. Rates for the packet
      capabilities will be determined via the Bona Fide Request/New Business
      Request Process.

   4  This rate element is for those states which have a specific rate for User
      Profile per B Channel.

   5  When CLEC buys the switch at the network element rate it will receive
      vertical services at no additional charge, but when it buys combinations
      of elements to produce a BellSouth retail service, and thus comes under
      the resale pricing provisions, it must also pay the wholesale rate for
      vertical services, if those services are in the retail tariff on the
      effective date of the agreement. Vertical services which are not in the
      retail tariff but which can be provided by the switch will be available at
      no additional charges. (NC)

   6  This rate element is for use in those states with a different rate for
      additional minutes of use.

   7  BellSouth and CLEC shall negotiate rates for this offering. If agreement
      is not reached within sixty (60) days of the Effective Date, either party
      may petition the Florida PSC to settle the disputed charge or charges
      (FL).

   8  This rate element is for those states w/o separate rates for 800 calls
      with 800 No. Delivery vs. POTS No. Delivery and calls with Optional
      Complex Features vs. w/o Optional Complex Features.

   9  This charge is only applicable where signaling usage measurement or
      billing capability does not exist.

   10 Prices for AIN to be determined upon development of mediation device
      (TN).

   11 Price for Line Class Codes for Selective Routing shall be determined by
      the TRA (TN).

NOTES:

If no rate is identified in the contract, the rate for the specific service or
function will be as set forth in applicable BellSouth tariff or as negotiated by
the parties upon request by either Party.

   1  Until the FCC issues its order implementing a cost recovery mechanism for
      permanent number portability, the Company will track its costs of
      providing interim SPNP with sufficient detail to verify the costs. This
      will facilitate the Florida PSCs consideration of the recovery of these
      costs in Docket 950737-TP (FL)

   2  BellSouth and CLEC will each bear their own costs of providing remote call
      forwarding as an interim number portability option. (KY)

                   Amendment to the Interconnection Agreement
               By and Between BellSouth Telecommunications, Inc.
                    And ITC/\DeltaCom Communications, Inc.
                               Dated June 5, 2000

     This Amendment ("Amendment") is made and entered into by and between
ITC/\DeltaCom Communications, Inc. ("ITC/\DeltaCom") and BellSouth
Telecommunications, Inc. ("BellSouth") and is intended to amend the
Interconnection Agreement (`The Agreement") entered into by ITC/\DeltaCom and
BellSouth on June 5, 2000. This Amendment shall be deemed effective on the date
executed by ITC/\DeltaCom and BellSouth.

     WHEREAS, ITC/\DeltaCom and BellSouth (individually, a "Party" and
collectively, the "Parties") have discovered that certain language was included
in the Agreement in error and such language had not been agreed upon by the
Parties; and

     WHEREAS, the Parties desire to amend the Agreement to reflect the actual
agreement of the Parties;

     NOW THEREFORE, in consideration of the provisions contained herein and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, ITC/\DeltaCom and BellSouth hereby covenant and agree as
follows:

     1.  Paragraph 6.4 of Attachment 4 of the Agreement shall be deleted in its
entirety, and in lieu thereof, a new Paragraph 6.4 of Attachment 4 shall be
included in the Agreement as follows:

          6.4  Construction and Provisioning Interval. BellSouth will negotiate
               --------------------------------------
               construction and provisioning intervals per request on an
               individual case basis. Excluding the time interval required to
               secure the appropriate government licenses and permits, BellSouth
               will use best efforts to complete construction for collocation
               arrangements under ordinary conditions as soon as possible and
               within a maximum of 90 business days from receipt of a complete
               and accurate Bona Fide Firm Order. Ordinary conditions are
               defined as space available with only minor changes to support
               systems required, such as but not limited to, HVAC, cabling and
               the power plant(s). Excluding the time interval required to
               secure the appropriate government licenses and permits, BellSouth
               will use best efforts to complete construction of all other
               collocation space ("extraordinary conditions") within 130
               business days of the receipt of a complete and accurate Bona Fide
               Firm Order. Extraordinary conditions are defined to include but
               are not limited to major BellSouth equipment rearrangement or
               addition; power plant addition or upgrade; major mechanical
               addition or upgrade; major upgrade for ADA compliance;
               environmental hazard or hazardous materials abatement.
