PROCEDURES FOR THE DERIVATION OF ACCOUNTING UNITS FOR DESIGNATED CABLES.

This Schedule provides procedures for the derivation of ACCOUNTING UNITS for
analogue and optical fibre DESIGNATED CABLES. ACCOUNTING UNITS for each
DESIGNATED CABLE and the percentage shares of ACCOUNTING UNITS for each
MAINTENANCE AUTHORITY are obtained on an EAST ZONE and WEST ZONE basis as shown
on Schedule Cl and Schedule C2 annexed to this Schedule. ACCOUNTING UNITS for
analogue and optical fibre DESIGNATED CABLES are based on the procedures
contained in this Schedule and Schedules Cl and C2 are prepared in accordance
with Article 7.

I.    ACCOUNTING UNIT COMPONENT AND FORMULAE

      1. ACCOUNTING UNIT Components.

      1.1   The ACCOUNTING UNITS for analogue and optical fibre cable systems in
            each ZONE are based on formulae that contain two or more of the
            following components respective to each DESIGNATED CABLE or part,
            segment or subsegment thereof in the respective ZONE:

      1.2 Where:  L1=   the number of unburied nautical miles from the beach
                        joint until the cable system is at a depth of 500
                        fathoms.

                  L2=   the number of unburied nautical miles between the points
                        where the cable system is at depths of 500 and 1,000
                        fathoms.

                  L3=   the number of nautical miles that the cable system is
                        buried from the beach joint until the cable system is at
                        a depth of 1,000 fathoms.

                  Bx=   the multiplier to be applied to the buried section
                        length of optical fibre cable systems, where:

III. INTRODUCTION OF NEW OR ADDITIONAL DESIGNATED CABLES

      Procedures for including new or additional cable systems into Schedules C1
      and/or C2 shall be as follows:

      1. GENERAL PROCEDURES

      1.1   In accordance with Article 7 cables may be added to Schedules C1,
            and/or C2. Since the date of inclusion of these cables will usually
            not correspond to either the analogue cable circuit count date, the
            bi-annual updates of Schedule C1 and C2 for analogue cables or the
            annual updates for optical fibre cables, the following procedures
            shall be used.

      1.2   Upon notification by the MAINTENANCE AUTHORITY of its desire to
            include a new or additional cable, segment, subsegment or activated
            spare capacity in this AGREEMENT, its date of inclusion and other
            required system information, Schedules C1 and/or C2 shall be amended
            effective the first day of the billing quarter that follows the date
            of introduction.

2. ANALOGUE CABLE SYSTEMS

      2.1   A new or additional analogue cable system shall be included in the
            AGREEMENT as a DESIGNATED CABLE with effect from the date of
            inclusion advised under Section III, Sub-paragraph 1.2 of this
            Schedule and shall be included in the next issue of Schedule C using
            the number of circuits in use on 1 January or 1 July as appropriate
            as shown on the appropriate ACMA Schedule B.

      2.2   No retrospective billing adjustment will be required of the CENTRAL
            BILLING PARTY for the period between the date of inclusion in this
            AGREEMENT and the effective date of the next Schedule C. However,
            during the first six (6) months of billing which includes the new or
            additional cable, the ACCOUNTING UNITS for the cable will be
            increased by an amount obtained by multiplying (i) the number of
            ACCOUNTING UNITS calculated in accordance with Section I,
            Subparagraph 2.1 of this Schedule by (ii) the amount of time, as a
            proportion of six (6) months, between the date of inclusion in this
            AGREEMENT and the effective date of the above-referenced Schedule C.

3. OPTICAL FIBRE CABLE SYSTEMS

<PAGE>

            3.1.1 As a new or additional cable systems is introduced into the
                  AGREEMENT, the optical fibre system ACCOUNTING UNIT formula
                  shall include the FF derived in accordance with Section 1,
                  Sub-paragraph 1.2 of this Schedule.

            3.1.2 For single fibre pair system with capacity below design level,
                  the Bearer Capacity shall be based on the assigned or Notional
                  Capacity.

            3.1.3 Introduction of Multi-Fibre Systems.

            a)    The same procedures shall be followed as described in the
                  preceding paragraphs 3.1.1. and 3.1.2. for systems with a
                  capacity below design level for each fibre pair. The sheath
                  mileage shall be counted once as shown in the formula in (b)
                  below.

            b)    Determine the Bearer Capacity of each fibre pair and apply the
                  FF of each fibre pair at the date of inclusion.

                  i)    ACCOUNTING UNITS = Cf where:

                  Cf = [L1 + L2/2 + (Bx x Lb)] x
                       [(Nfl x FF1)+ (Nf2 x FF2)]/1,000

                  ii)   Where: Nf1 and FF1 apply to the first fibre pair and Nf2
                        and FF2 apply to the second fibre pair. For systems with
                        more than two fibre pairs, "f3 x FF3" and so on are
                        inserted into the formula.

            c)    For branched cable systems the Bearer capacity and associated
                  ACCOUNTING UNITS for each segment or subsegment shall be
                  determined separately, and so displayed on the applicable
                  Schedules C1 and/or C2.

      3.2   The introduction of Newly Equipped Spare Capacity.

            3.2.1 When the Bearer Capacity of a DESIGNATED CABLE is expanded,
                  the Bearer Capacity of the system shall be adjusted to reflect
                  the new capacity as defined in the amended relevant C&MA.

<PAGE>

            3.2.2 The ACCOUNTING UNITS for newly equipped spare fibre pairs or
                  the expansion of a cable beyond its initial capacity shall be
                  based on the following formula:

                  i)    ACCOUNTING UNITS = Df where:

                  Df=[L1 + L2/2 + (Bx x Lb)] x [(Nf1 x FF1) +Nf2 x FF2)]/1,000

                  ii)   Where: Nf1 and FF1 apply to the original capacity and NV
                        and FF2 apply to the new equipped or expanded capacity.

            3.2.3 The Beater Capacity of the original capacity shall be
                  determined in accordance with the reasons in the relevant C&MA
                  for justifying the expanded capacity as follows:

                  i)    If the expansion of the system is the result of the
                        original capacity reaching full utilisation, the FF1
                        applied to Nf1 shall be 1.0.

                  ii)   If the expansion was not the result of the original
                        capacity being fully utilised, the FF1 shall continue at
                        its current assigned FE at the time the spare capacity
                        is activated.

                  iii)  If the amended C&MA indicates another Bearer Capacity or
                        other level of utilisation, the Bearer Capacity or the
                        FF1 as appropriate should be adjusted accordingly.

                  iv)   The FF of the newly equipped and original fibre pair
                        shall be adjusted annually as specified in Part II,
                        Paragraph 3.1.2 of this Schedule.

            3.2.4 Total ACCOUNTING UNITS for the cable system, segment or
                  subsegment shall be determined on the basis of cumulative
                  totals for the original and subsequently activated capacities
                  in those cases where more than one FF is used and the
                  MAINTENANCE AUTHORITIES and cable system terminals are the
                  same. Where the MAINTENANCE AUTHORITIES and/or system or
                  segment terminals are different, the ACCOUNTING UNITS shall be
                  displayed separately on schedule Cl and/or C2 as appropriate.

IV. CABLES WITHDRAWN FROM SERVICE AND THE REDUCTION OF NOTIONAL CAPACITY.

      1. CABLE WITHDRAWN FROM SERVICE

            1.1   When a DESIGNATED CABLE is withdrawn from service, the
                  MAINTENANCE AUTHORITY responsible shall inform the Chairman of
                  the OPERATING COMMITTEE and the Appointed Party of the date of
                  withdrawal. The Appointed Party shall amend Schedule C by
                  deleting the cable, and shall issue a revised Schedule Cl
                  and/or C2, effective the date of withdrawal from service.

      2. REDUCTION OF NOTIONAL CAPACITY.

            2.1   There may be circumstances for optical fibre cable systems, or
                  segments or subsegments where some capacity might not be
                  usable as a result of a mis-match with interconnecting
                  facilities, a condition of isolation due to circuits turned
                  back to the owners, or other conditions where the use of such
                  capacity is not available to the cable owners. The MAINTENANCE
                  AUTHORITY(s) concerned shall advise the OPERATING COMMITTEE of
                  those circumstances where the unavailability is deemed
                  permanent in nature, and upon approval of the OPERATING
                  COMMITTEE, the Notional Capacity shall be correspondingly
                  reduced in the ACCOUNTING UNIT formula.

            2.2   The Notional Capacity of the cable system, segment or
                  subsegment shall be reduced in accordance with Paragraph 2.1
                  above and Schedule C1 and/or C2 shall be amended accordingly
                  effective the first day of the following quarter. The FF would
                  continue as previously assigned.
