                                   SCHEDULE I

                              DESCRIPTION OF SYSTEM

A trans-Atlantic cable system which is to operate from London and Paris to New
York and will include trans-Atlantic subsea elements and backhaul elements in
Europe and the United States.

The subsea elements will involve the construction of four landing stations ("the
Landing Stations"), three submarine cable sub-segments, Long Island North (USA)
-- UK, UK -- France and France -- Long Island South (USA) each containing six
fiber pairs. The Landing Stations are currently expected to be at (i) Cornwall
(UK), (ii) St. Brieuc (France), (iii) Makamah Beach on the North shore of Long
Island, New York (USA) and (iv) Long Beach on the South shore of Long Island,
New York (USA). Each amplified fiber pair will be designed for a minimum
capacity of 40 wavelengths with each wavelength running at 10 Gbps. The fiber
pair on which the Purchaser will derive its capacity in accordance with this
Agreement in each of the three submarine cable sub-segments will be initially
equipped with 40 Gbps of capacity structured as 4 wavelengths each operating at
10 Gbps. Such fiber pair will be equipped with amplifiers, dedicated SLTEs and
four transponders per SLTE.

The backhaul elements will connect the Landing Stations to an optical
input/output port on the optical distribution frame ("Terminal Point") in
London, Paris, New York City and, at the absolute discretion of FA-1, New Jersey
or to the applicable breakout point where Purchaser has chosen to intercept the
fiber at a splice case or joint box close to the applicable Terminal Point.

For Purchaser, the backhaul elements will consist of concatenated single fiber
pairs meeting either (at the absolute discretion of FA-1) ITU-T G.655 or G.652
requirements as well as sufficient space for repeaters and regenerators at sites
chosen by FA-1 for its own repeaters and regenerators, as detailed in the
collocation and maintenance agreement referred to in clause 2.7.

For Purchaser the system does not include SDH- ATM, or IP interfaces for the
Submarine IRU nor the electronic and optronic equipment necessary for
Purchaser's transmission of data on the Terrestrial IRU, including any equipment
used to derive channels from the Dark Fiber.

The Initial Stage of the system will consist of the Northern subsea link from
Cornwall to the North shore of Long Island, the Cornwall to Brittany
Trans-Channel link and the backhaul elements (which includes the terrestrial
link between the North shore and the South shore of Long Island). The Final
Stage will consist of the Initial Stage and the Southern subsea link from
Brittany, France to the south shore of Long Island.

FA-1 expects to meet the following milestones:

1.    Access to Dark Fiber and transmission stations -- 31 January 2001
2.    Initial RFS Date -- 31 March 2001
3.    Final RFS Date -- 30 June 2001

Date: 18th September 1987                 Your Ref:
                                          Our Ref: RE S3/55 Vol. 17

To: Parties shown in the attached lists

Dear Sirs

1ST SUPPLEMENTAL AGREEMENT TO THE SOUTH-EAST-ASIA AND INDIAN OCEAN CABLE
MAINTENANCE AGREEMENT (SEAIOCMA)

      We refer to the 3rd South-East-Asia and Indian ocean Cable Maintenance
Agreement (SEAIOCMA) Management Committee Meeting held between 11 May to 12 May
87 in Jakarta, and to paragraph 11 of the minutes thereof, wherein we sought
clarification on the ambit of Clause 1 of the above Supplemental Agreement.

2 The explanation as given to us therein was that the said provision is intended
to deal with a situation where, as a result of anyone of those causes, records
of the Maintenance Authority were destroyed making it unable to make the
required payment until it had been furnished with the replacement of the bill
etc. by the Facility Providers. It is during this interim period that interest
on the deferred payment should not be paid by the Maintenance Authority. We
have, on the basis that the explanation will be binding on all the parties,
proceeded to sign this Supplemental Agreement as a signatory.

3 As also agreed therein, a copy of this letter of ours will be attached to each
counterpart of this Supplemental Agreement.

Yours faithfully

for & on behalf of Telecoms

                   CABLESHIP FIXED STANDING CHARGE ALLOCATION

1.    The Cableship Fixed Standing Charge will be allocated to each Scheduled
      Cable in accordance with the PIOCAU Cost Allocation Formula as defined
      below:-

      The PIOCAU Cost Allocation Formula is:-

      PIOCAUs = NM [1 + (Bearer Capacity x Fill Factor/5000)]

      Where:

      a)    NM equals the Chargeable Sheath Mileage of a cable system.

      b)    Bearer capacity is the assigned, notional or design capacity
            whichever is used as the basis of ownership of each segment of a
            cable system as identified in the relevant Construction and
            Maintenance Agreement, or its equivalent, for that cable system.

            (The assigned or notional capacity is that which would normally
            accommodate the traffic requirements of a cable system for at least
            10 years from RFS date).

      c)    Fill Factors are shown below on the basis of notional years of
            service for each cable system and/or segment from its ready for
            service date (RFS).

(d)   For the purposes of paragraph (c) above, notional years of services for
      Scheduled Cables shall be determined as follows:-

      (i)   A Scheduled Cable shall commence its first notional year of service
            on its RFS date; and

      (ii)  A Scheduled Cable shall commence its second notional year of service
            on 1st July of the year following the calendar year of its RFS date
            and shall commence subsequent notional years of service on 1st July
            of subsequent years.

(e)   The Cableship Operators will automatically apply the fill factor for new
      cables entering the zone, adjust the fill factor for existing Scheduled
      Cables in accordance with paragraphs (c) and (d) above, remove cables from
      the Schedules with effect from the dates they are withdrawn from service
      and circulate amended Schedules to all parties to this agreement as soon
      as practicable after each amendment.

2.    Where a Scheduled Cable or part of a Schedule Cable shown in Schedule C is
      2000 nautical miles or more from the base port of the Cableship in that
      Normal Operational Zone then, for PIOCAU calculation, the amount of the
      Scheduled Cable beyond the 2000 nautical miles shall be considered as half
      its actual length and this added to the cable length within 2000 nautical
      miles shall be the Chargeable Sheath Mileage.

3.    For Maintenance Authorities whose Scheduled Cables carry wholely or
      partially domestic or non-commercial circuits, the following formula shall
      apply for PIOCAU calculation purposes.

                                   Z = Y/2 x X

                                                                     Page 4 of 8

WHERE:      X     = the Chargeable Sheath Mileage of a Scheduled Cable between
                  landing points (after adjustment calculated in accordance with
                  paragraph 2 above)

            Y     = the ratio of domestic or non-commercial circuits to all the
                  used circuits carried on the Scheduled Cable

            Z     = gives the discounted section of the Scheduled Cable.

      Then X - Z shall give the Chargeable Sheath Mileage to be included in the
      PIOCAU Cost Allocation Formula for derivation of the costs to be allocated
      to the Maintenance Authority eligible for such discount.

4.    Page 5 of this schedule indicates the cost allocation to each Scheduled
      Cable calculated on the basis of (l), (2) and (3) above. The effective
      length of Scheduled Cable after application of (2) and (3) is the
      Chargeable Sheath Mileage. The Chargeable Sheath Mileage shall be included
      in the PIOCAU Cost Allocation Formula and the number of PIOCAUs shall be
      calculated in accordance with (1) above.

5.    Maintenance Authorities shall keep the Management Committee and the
      Cableship Operators advised of any change in the ratio (Y) of domestic or
      non-commercial circuits currently on the Scheduled Cables in proportion to
      all the traffic carried on the Scheduled Cables, for which they have
      responsibility. Page 5 of this schedule shall be amended from time to time
      as necessary.

6.    Maintenance Authorities shall. advise the Management Committee of the
      Bearer Capacity applicable to each Scheduled Cable.

                                                                     Page 1 of 2

                          PRIORITY REPAIR ARRANGEMENTS

This Schedule provides procedures pertaining to Priority Repair Arrangements.

In the event of simultaneous cable failures the priority of repair should be
guided by the principle of mutual cooperation between Maintenance Authorities
when electing to invoke Priority Repair Arrangements. The Maintenance
Authorities should recognize circumstances where a small failed system (lower
priority) might be more vital to its owners than the larger failed system and
conditions might exist where the owners of a smaller system may be in isolation
due to the failure.

Unless other arrangements are agreed by the Maintenance Authorities involved,
the priority of repair should be in accordance with the procedures set out
below.

1.    Determination of Priority Factor

      A Priority Factor (P/F) should be established for each Scheduled Cable.
      The P/F is determined from the following formula:

                                 P/F = PIOCAU's
                                       --------
                                         NM

      Where:

      -     PIOCAU's equal the value of PIOCAU's calculated for each Scheduled
            Cable.

      -     NM is the Chargeable Sheath Mileage in Nautical Miles for the
            Scheduled Cable.

            The Priority Factor of each Scheduled Cable is shown in page 5 of
            Schedule D2 next to its respective PIOCAU rating.

                                                                     Page 2 of 2

2.    Procedures to Implement Priority Repair Arrangements

      (a)   The Scheduled Cable with the highest Priority Factor is first cable
            to be repaired.

      (b)   If the Priority Factors of the cables are equal, the Scheduled Cable
            with the highest number of PIOCAU's is first repaired.

      (c)   If the PIOCAU's of the Scheduled Cables are the same, the
            Maintenance Authority that calls first for the repair ship is first
            served.

            C.S. Cable Enterprise shall cease to apply in respect thereof upon
            the respective dates that each of these vessels is replaced by a New
            Vessel.

      (e)   Should a New Vessel replace an existing Cableship in the course of a
            Financial Year the Fixed Standing Charge chargeable for that
            Financial Year shall be the aggregate of the proportionate amount of
            Fixed Standing Charge of the Cableship being replaced and that of

                   CABLESHIP FIXED STANDING CHARGE ALLOCATION

1.    The Cableship Fixed Standing Charge will be allocated to each scheduled
      Cable in accordance with the PIOCAU Cost Allocation Formula as defined
      below:-

      The PIOCAU Cost Allocation Formula is:-

      PIOCAUs - NM [I + (Bearer Capacity x Fill Factor/5000)]

      Where:
      a)    NM equals the Chargeable Sheath Mileage of a cable system.

      b)    Bearer Capacity is the assigned, notional or design capacity
            whichever is used as the basis of ownership of each segment of a
            cable system as identified in the relevant Construction and
            Maintenance Agreement (C&MA"), or its equivalent, for that cable
            system.

            (The assigned or notional capacity is that which would normally
            accommodate the traffic requirement of a cable system for at least
            10 years from RFS date except as specified in Paragraph (c) (ii)
            below

      c)    Fill Factors (FF) as shown below, are applied on the basis of years
            of service for each Scheduled Cable from its Ready For Service (RFS)
            date. The FF are intended to reflect system utilization from traffic
            forecasts. The 10 year FF are assigned to all the Scheduled cables
            except as specified in Paragraph (c) (ii) below.

                  entities on a "demand basis" and no Notional Capacity is
                  listed in the cable's C&MA, the maintenance authority (ies) of
                  said cable system shall submit in writing to the Maintenance
                  Authority (ies) for approval the activated capacity of the
                  cable system to be used as Bearer Capacity. Fill Factor to be
                  used is 1.00.

      d)    For the purpose of paragraph (c) above, notional years of service
            for Scheduled Cable shall be determined as follows:-

            (i)   A Scheduled Cable shall commence its first notional year of
                  service on its RFS date except as specified in Paragraph (c)
                  (ii) above; and

            (ii)  A Scheduled Cable shall commence its second notional year of
                  service on 1st July of the year following the calendar year of
                  its RFS date and shall commence subsequent notional years of
                  service on 1st July of subsequent years except as specified in
                  Paragraph (c) (ii) above.

      e)    The Cableship Operators will automatically apply the fill factor for
            new cable entering the zone, adjust the fill factor for existing
            Scheduled Cable in accordance with paragraphs (c) and (d) above
            except as specified in Paragraph (c) (ii) above.

      f)    The Cableship Operators will automatically remove cables from the
            Schedule with effect from the dates they are withdrawn from service
            and circulate amended Schedule to all parties to this agreement as
            soon as possible.

2.    Where a Scheduled Cable or part of a Scheduled Cable shown in Schedule C
      is 2000 nautical miles or more from the base port of the Cableship in that
      Normal Operational Zone then, for PIOCAU calculation, the amount of the
      Scheduled Cable beyond the 2000 nautical miles shall be considered as half
      its actual length and this added to the cable length with 2000 nautical
      miles shall be the Chargeable Sheath Mileage.

                                                          Effective 3 April 1997

      or non-commercial circuits, the following formula shall apply for PIOCAU
      calculation purpose.

            Z=Y/2 x X

      Where:

            X=    the Chargeable Sheath Mileage of a Scheduled Cable between
                  landing points (after adjustment calculate in accordance with
                  paragraph 2 above)

            Y=    the ratio of domestic or non-commercial circuit to all the
                  used circuits carried on the Scheduled Cable

            Z=    gives the discounted section of the Scheduled Cable.

      Then X - Z-shall give the Chargeable Sheath Mileage to be included in the
      PIOCAU Cost Allocation Formula for derivation of the costs to be allocated
      to the Maintenance Authorities eligible for such discount.

4.    Page 5 of this schedule indicates the cost allocation to each Schedule
      Cable calculated on the basis of (1), (2) and (3) above. The effective
      length of Schedule Cable after application of (2) and (3) is the
      Chargeable Sheath Mileage. The Chargeable Sheath Mileage shall be included
      in the PIOCAU Cost Allocation Formula and the number of PIOCAUs shall be
      calculated in accordance with (1) above.

5.    Maintenance Authorities shall keep the Management Committee and the
      Cableship Operators advised of any change in the ratio (Y) of domestic or
      non-commercial circuits currently on the Scheduled Cable in proportion to
      all the traffic carried on the Scheduled Cables, for which they have
      responsibility. Page 5 of this schedule shall be amended from time to time
      as necessary.

6.    Maintenance Authorities shall advise the Management Committee of the
      Bearer Capacity, or Activated Capacity as specified in Paragraph (c) (ii)
      above, applicable to each Schedule Cable.

      Billing parties in accordance with and as indicated in Clause 21 (j) and
      Schedule B2.

      Amendment to the Chargeable Sheath Mileage shall be subject to the
      approval of the Management Committee and shall be effective from the date
      of such notification unless otherwise agreed.

8.    Whenever Sheath Mileage, Bearer Capacity/Activated capacity or Fill Factor
      of a Schedule Cable is revised, the PIOCAU's for said Schedule Cable shall
      be recalculated, and the total PIOCAU's for the Scheduled Cables shall
      also be recalculated and the Order of Priority for the Scheduled Cable
      shall be determined in accordance with Schedule M and Schedule D2 shall be
      revised and distributed to each Party by CW(M).

                       BASIC CABLESHIP TECHNICAL CRITERIA

1.    An outline specification of the C S Cable Enterprise and C S Retriever is
      given in this Schedule G.

2.    The operational capabilities of both Cableships include the following:

      (i)   Both vessels are capable of undertaking the repair of all Scheduled
            analogue (coaxial) Cables including those of French, Japanese,
            American and British manufacture except in the case of American
            cable-to-repeater joints.

      (ii)  Both vessels are capable of undertaking the repair of all optical
            fibre Scheduled Cables.

      (iii) Both vessels are capable of handling and testing all types of
            analogue (coaxial) repeaters and equalisers in use in the
            Operational Zone at the effective date of the Agreement including
            temperature compensating repeaters, both Cableships being equipped
            with a thermally insulated repeater stack which holds powered
            repeaters at a stable working temperature.

      (iv)  Both vessels are capable of handling, powering and testing the
            optical fibre Scheduled Cables in the Operational Zone. A list of
            basic, common testing and associated equipment is shown in Annex I
            to this Schedule G. Each vessel is capable of testing and jointing
            of the optical fibre repeaters and cable in the Operational Zone and
            each Vessel is equipped to suit the needs of the systems in its
            Normal Operational Zone.

      (v)   The Maintenance Authorities will, unless otherwise agreed, provide
            the vessel covering the Normal Operational Zone in which its cable
            is listed with the necessary jointing and specialised test
            equipment, required by the Maintenance Authority to be carried in
            order to maintain its cable, over and above the equipment listed in
            Annex 1 to this Schedule G.

      (vi)  Where the vessel attends an optical fibre Scheduled Cable outside
            its Normal Operational Zone and the faulty cable is of the same type
            the vessel maintains in its Normal Operational Zone then the
            Cableship Operator will request the Maintenance Authority who has
            provided the specialised test and jointing equipment relevant to the
            two systems for permission to use this equipment on the faulty
            cable.

            [Maintenance Authorities are requested to keep the Cableship
            Operators informed of any agreements reached between them on the
            common sharing of equipment and pooling of spare cable and plant.]

      (vii) Both vessels are capable of undertaking shallow and deep-water
            repairs and of carrying sufficient quantities of rope, buoys,
            grapnels and other associated items normally required for such
            repair.

      (viii) Both vessels are capable of carrying different types of cables,
            repeaters, branching units and coupling tails at any one time for
            the Scheduled Cables.

      (ix)  Both vessels are capable of handling remotely controlled submersible
            vehicles (RCSVs).

WORK PACKAGE

The work package is designed to assist in cable repair and maintenance, post lay
inspections and re-burial operations. It is equipped with a Simrad nighthawk SIT
Low Light Level Underwater Camera and an Innovatum cable locator system. With
these two sets of equipment, the ROV operator is provided with a clear vision
even in the most remote areas at 2,000 meters below sea level.

The package is also installed with the Schilling TITAN III manipulator,
incorporating state-of-the-art technology. This pair of "arms" is designed
specifically for heavy duty work underwater, such as retriving cables and cable
re-burial operations.

Installed with such a good cable tracking system, a camera that provides clear
vision in the dark, and a pair of strong "arms", the operator is virtually
unhindered by any obstacles when locating cables.

Weddelli, a cable maintenance Remotely Operated Vehicle (ROV) named after a deep
diving seal, has an umbilical cable of 2,500 meters in length and is able to
operate at a water depth of 2,000 meters.

She is specially built for the purpose of assisting in repair and maintenance of
submarine cables. Her responsibility and role in ACPL has had a tremendous
impact on conventional cable retrieving methods such as the grapnel. Using her
will increase accuracy and speed of operation. Her ability and versatility have
given her the ability to trace and retrieve buried cables normally undertaken by
divers. In addition, she is designed to operate underwater for an indefinite
time period. As for divers, they can only operate underwater for a limited time
period.

Her mobility and flexibility allow her to be deployed on any vessel of
opportunity to carry out subsea missions as required.

Weddelli is manned by the Subsea Unit formed by ACPL's staff who have been
trained professionally and are continually being upgraded to meet customers'
needs.

                          PRIORITY REPAIR ARRANGEMENTS

This Schedule provides procedures pertaining to Priority Repair Arrangements.

In the event of simultaneous cable failures the priority of repair should be
guided by the principle of mutual cooperation between Maintenance Authorities
when electing to invoke Priority Repair Arrangements. The Maintenance
Authorities should recognize circumstances where a small failed system (lower
priority) might be more vital to its owners than the larger failed system and
conditions might exist where the owners of a smaller system may be in isolation
due to the failure.

For the purpose of this Schedule simultaneous cable failures shall be deemed to
have occurred when a written fault notification is received by the Cableship
Operators within 24 hours of a previous written fault notification.

Unless other arrangements are agreed by the Maintenance Authorities involved,
the priority of repair should be in accordance with the procedures set out
below.

Determination and implementation of Priority Factor

1.    A Priority Factor (P/F) shall be established for each Scheduled Cable in
      accordance with the number of PIOCAUs calculated for the Scheduled Cables.
      The Scheduled Cable with the highest number of PIOCAUs will have priority
      over the Cableship in the case of a simultaneous cable failure as defined
      above.

2.    For the purposes of calculating the Priority Factor, unless agreed
      otherwise by the Management Committee, all branched sub-segments of a
      Scheduled Cable shall be considered as one cable system. Calculation of
      the overall PIOCAUs of these cable systems will be based on the individual
      sum of each sub-segment's PIOCAUs.

3.    If the Priority Factor of the Scheduled Cables is the same, the
      Maintenance Authority that calls first for the Cableship is first served.

4.    Schedule D2 identifies the Priority Factor for each Scheduled Cable.

5.    The Priority Factor will be reviewed at each MC meeting.

                         ROV STANDING CHARGE ALLOCATION

I.    The ROV Standing Charge will be allocated to each Scheduled Cable in
      accordance with the ROV cost allocation formula which is defined as
      follows:

      ROV Accounting Units ("RAUs") = L1 + 0.5L2 + 4B

      where:

      o     L1 = Unburied cable length in water depths between 0-1000 metres.

      o     L2 = Unburied cable length in water depths between 1000-2000 metres.

      o     B = Total buried cable length.

2.    L1, L2, and B, above, will be adjusted according to the following rules:

      (i)   Where a Scheduled Cable or part of a Scheduled Cable is 2,000
            nautical miles or more from the base port of the Cableship in its
            Normal Operating Zone, for the purposes of allocating ROV Standing
            Charges, the amount of the Scheduled Cable beyond 2,000 nautical
            miles shall be considered half its actual length, and this added to
            the cable length within 2,000 nautical miles shall be used in
            calculating L1, L2, and B.

      (ii)  For Scheduled Cables that carry wholly or partially domestic
            traffic, the following formula shall apply for RAU calculation
            purposes:

            Z=Y/2 x X

            Where:

      o     X = Chargeable Sheath Mileage of a Scheduled Cable between landing
            points (after adjustment calculated in accordance with para 2(i)
            above.

      o     Y = The ratio of domestic circuits to all used circuits carried on
            the Scheduled Cable.

      o     Z = The discounted section of the Scheduled Cable.

<PAGE>

            X - Z is the cable length to be used in the calculation of L1, L2,
            and B for determining the allocation of ROV Standing Charges.

3.    The attached tables, 'ROV Cost Allocation to Scheduled Cables', shows the
      ROV Standing Charge allocation to each Scheduled Cable calculated on the
      basis of (1) and (2) above, and the billing and liability for payment
      parties for each Scheduled Cable. These tables will be amended as
      necessary from time to time.

                                   WITNESSETH

WHEREAS by an agreement dated 1 June 1986 between the Maintenance Authorities
and the Cableship Operators as named therein ("SEAIOCMA"), as amended by a First
Supplemental Agreement dated 1 December 1986, a Second Supplemental Agreement
dated 1 June 1990, and a Third Supplemental Agreement dated 17 September 1992,
the Cableship Operators agreed to provide facilities and services within the
Operational Zone.

WHEREAS the increasing number of buried cable systems in the Operational Zone
has necessitated the introduction of submersible facilities to assist the
Cableship Operators in maintaining buried cable systems.

WHEREAS the Maintenance Authorities have agreed to the enhancement of the
Cableships' facilities by the inclusion of remotely operated vehicles.

WHEREAS the Cableship Operators are required to undertake jointer training and
requalification of jointers, and the Maintenance Authorities have agreed to pay
for the costs associated with such activities.

WHEREAS the Parties have agreed to the need to reference Schedule M in the text
of SEAIOCMA.

NOW THEREFORE, the Parties agree with one another as follows:-

1.    DEFINITIONS

      Save as is herein amended, the words and/or expressions as used in the
      Fourth Supplemental Agreement shall have the same meanings ascribed to
      them as in SEAIOCMA, the First Supplemental Agreement, the Second
      Supplemental Agreement, and the Third Supplemental Agreement.

      Clause 1 of SEAIOCMA shall be amended as follows;

      "ROV"                   means the CIRRUS ROV or any new remotely operated
                              vehicle provided by the Cableship Operators under
                              SEAIOCMA as more fully described in Schedule N.

      "ROV Running Costs"     means the variable costs for an ROV as defined in
                              Schedule O over and above the ROV Standing Charges
                              incurred in respect of repairs, maintenance, and
                              other such operational circumstances as stipulated
                              in the Agreement.

                                       3
<PAGE>

      "ROV Standing Charges" means the annual charges as allocated in Schedule
      P, payable to the Cableship Operators in consideration of the provision
      of ROVs as detailed in Clause 3 of the Fourth Supplemental Agreement.

2.    PROVISION OF ROV FACILITIES

a)    In accordance with Clause 5(f) of SEAIOCMA, the Cableship Operators will
      provide ROVs as additional facilities under the Agreement.

b)    As from 1st October 1995, CWM shall provide the CIRRUS ROV on the C.S.
      Cable Enterprise and thereafter on the New Vessel ("Vessel 2") after it
      replaces the C.S. Cable Enterprise, until such time that CIRRUS is
      replaced by a new ROV in accordance with Clause 2(c)(ii) of this Fourth
      Supplemental Agreement. The specification of the CIRRUS ROV is appended
      hereto as Schedule N.

c)    The Cableship Operators shall procure new ROVs based on the target
      specification which is appended hereto as Schedule N, as follows:

      (i)   A new ROV ("ROV 1") shall be procured by ACPL and installed on
            Vessel I (hereinafter called C.S. ASEAN Restorer) by 1st December
            1995 or as soon as possible thereafter.

      (ii)  A new ROV ("ROV 2") shall be procured by CWM and installed on Vessel
            2 by 1st January 1999 or as soon as possible thereafter.

d)    The CIRRUS ROV shall accordingly be withdrawn from SEAIOCMA as at the date
      of its replacement by ROV 2 as specified above and the Maintenance
      Authorities shall incur no further obligation or liability for the CIRRUS
      ROV thereafter.

(e)   When each new ROV is delivered by the manufacturer to ACPL and CWM
      respectively, their specifications shall be incorporated as Schedule N and
      shall supersede the target specifications appended hereto.

3.    ROV STANDING CHARGES

(a)   In consideration of the provision of ROVs on the Cableships, the
      Maintenance Authorities shall pay annual ROV Standing Charges in addition
      to the annual Fixed Standing Charges as follows:

                                       4

      (i)   CIRRUS

            1995/96        (pound)824,400
            1996/97        (pound)857,700
            1997/98        (pound)891,900
            1998/99        (pound)927,000

      (ii)  ROV 1

            1995/96        Sing$2,850,000
            1996/97        Sing$2,964,000
            1997/98        Sing$3,082,750
            1998/99        Sing$3,206,250

      (iii) ROV 2

            1998/99        (pound)1,381,300
            1999/2000      (pound)1,439,250
            2000/01        (pound)1,496,250

b)    It is recognized by the Parties that the ROV Standing Charges in respect
      of ROV 2 as detailed above are based on the current expectations of the
      capital cost of ROV 2 as detailed in paper 21 of SEAIOCMA Management
      Committee meeting 11. In the event that the actual capital cost differs
      from the current expectation due to a different cost being quoted from the
      supplier, or as a result of changes in prevailing exchange rates, CWM
      shall re-compute the ROV Standing Charges in respect of ROV 2, and
      re-submit them for approval of the Management Committee. Such approval
      shall not be unreasonably withheld. ROV Standing Charges re-submitted and
      agreed under this clause shall replace the ROV Standing Charges in respect
      of ROV 2 as detailed in Clause 33 (a)(iii) of the Fourth Supplemental
      Agreement.

c)    Should an ROV be incorporated into or withdrawn from SEAIOCMA during the
      course of a Financial Year, the ROV Standing Charge applicable to that
      Financial Year shall be pro-rated accordingly.

d)    The ROV Standing Charges subsequent to those indicated in Clause 3(a) of
      the Fourth Supplemental Agreement shall be subject to an annual increase
      of 4% from the previous year.

e)    ROV Running Costs incurred during an operation are calculated in
      accordance with Schedule 0, appended hereto.

                                       5
<PAGE>

4.    BASIS OF ROV COST ALLOCATION

      The ROV Standing Charges shall be allocated to the Maintenance Authorities
      in proportion to each Scheduled Cable's allocated number of ROV Accounting
      Units as determined in accordance with the provisions of Schedule P
      attached to this Fourth Supplemental Agreement.

5.    OPERATION OF THE CABLESHIPS

      The following sub-clauses shall be incorporated in SEAIOCMA as new clauses
      7(i) and 7(j);

      "7(1) At the inception of the Fourth Supplemental Agreement, the Cableship
            Operators undertake to commence negotiations with a suitable local
            company to supply additional ROV personnel during operations that
            require the use of an ROV. It is recognised and agreed by the
            Maintenance Authorities that until such arrangements are finalised,
            in such instances where an ROV is required, the Cableship Operators
            will use reasonable endeavours to put the Cableship to sea in
            accordance with Clause 7 of SEAIOCMA."

      "7(j) Notwithstanding sub-clause 7(i) above, in the event that an ROV is
            required to assist in a maintenance or repair operation, the
            Cableship Operators undertake to mobilise the additional ROV
            personnel with due dispatch."

6.    JOINTER TRAINING AND REOUALIFICATION COSTS

      The following sub-clause shall be incorporated in SEAIOCMA as new clause
      19(n):

      "Any costs incurred by the Cableship Operators in respect of training and
      re-qualifying jointers to provide jointing services under this Agreement
      shall be allocated to the Scheduled Cables in proportion to their
      allocated number of PIOCAUs in accordance with Schedule D2 prevailing at
      the time that such training or re-qualification costs were incurred".

7.    BILLING, ACCOUNTING AND SETTLEMENT ARRANGEMENTS

      Clause 21(b) of SEAIOCMA shall be amended by the addition of the following
      text;

      "Bills in respect of an ROV shall be submitted on a quarterly basis to the
      Maintenance Authorities fifteen (15) days prior to the first date of the
      quarter in which they apply, save

                                       6
<PAGE>

      that the first quarterly bill in respect of the CIRRUS ROV will be
      submitted at the date of the Fourth Supplemental Agreement".

8.    PERFORMANCE OF ROV OPERATION'S

      The Cableship Operators shall with due dispatch, use reasonable skill and
      care in undertaking ROV operations, but the Cableship Operators shall not
      be subject to any undertaking, express or implied, as to the depth or
      speed of burial, such performance and time being dependent on the
      circumstances in which the Cableship and the ROV are required to operate.

9.    USE OF ROVs FOR OUTSIDE CHARTER

(a)   The Cableship Operators shall be at liberty to seek outside charter work
      for the ROVs. If such work requires the use of an ROV only, without a
      requirement for the Cableship, then the Cableship Operator shall seek the
      prior agreement of the Management Committee to demobilise the ROV from its
      Cableship. Such agreement shall not be unreasonably withheld.

(b)   In the event that the Cableship Operators utilise an ROV for outside
      charter work, the Maintenance Authorities shall receive a daily rebate for
      the period during which the ROV is not available to the Maintenance
      Authorities. Such daily rebate will be an amount equal to the daily rate
      of the ROV Standing Charge calculated by dividing the ROV Standing Charge
      by 335.

(c)   The rebate due to the Maintenance Authorities at the end of such periods
      of outside charter work shall be allocated to the Maintenance Authorities
      in accordance with Schedule P appended hereto.

(d)   In the event that the Cableship is required for outside charier work
      without the need of an ROV, the Cableship Operator shall seek the prior
      permission of the Management Committee to release the Cableship only from
      its obligations under SEAIOCMA. Under such circumstances and if required
      by the Management Committee, the ROV will be demobilised at no cost to the
      Maintenance Authorities and shall be stored ashore in a state of
      operational readiness. The ROV Standing Charges will continue to be
      chargeable during outside charter work undertaken in accordance with this
      Clause 9 (d).

(e)   Should the ROV be required by a Maintenance Authority whilst the Cableship
      is on outside charier work as envisaged in Clause 9(d) above, the
      Cableship Operator shall assist the Maintenance Authority that requires
      the ROV in sourcing a suitable vessel of opportunity on which to mobilise
      the ROV. All costs incurred in providing a suitable

                                       7
<PAGE>

      vessel of opportunity, including but not limited to the cost of fitout of
      the vessel and mobilisation of the ROV shall be charged as ROV Running
      Costs as detailed in Schedule O.

10.   LOSS OF ROVs

(a)   In the event that an ROV is lost or becomes a constructive or actual loss,
      the Cableship Operator responsible for the operation of that ROV shall
      immediately notify all Parties, and shall use reasonable endeavours to
      secure an equivalent facility. If such a facility is available, the
      Parties agree to negotiate in good faith the terms and conditions for the
      provision of such a facility with the relevant Cableship Operator.

(b)   Should the Parties not agree to the provision of an equivalent facility,
      the ROV Standing Charge in respect of the lost ROV will cease to be
      charged as of the date of such loss.

11.   PREVIOUS AGREEMENTS

      Prior to the date of this Agreement, certain Parties hereto had rights and
      obligations under the CIRRUS ROV Insurance Premium Scheme. It is hereby
      agreed by the Parties that all rights and obligations under the CIRRUS ROV
      Insurance Premium Scheme shall terminate when the CIRRUS ROV is
      incorporated into SEAIOCMA in accordance with Clause 2(b) of this Fourth
      Supplemental Agreement, and that this Agreement shall supersede the CIRRUS

                         ROV STANDING CHARGE ALLOCATION

1.    The ROV Standing Charge will be allocated to each Scheduled Cable in
      accordance with the ROV cost allocation formula which is defined as
      follows:

      ROV Accounting Units ("RAUs") = L1 / 0.5L2 / 4B

      where:

      o     L1 = Unburied cable length in water depths between 0-1000 metres.

      o     L2 = Unburied cable length in water depths between 1000-2000 metres.

      o     B = Total buried cable length.

2.    L1, L2, and B, above, will be adjusting according to the following rules:

      (i)   Where a Scheduled Cable or part of a Scheduled Cable is 2,000
            nautical miles or more or more from the base port of the Cableship
            in its Normal Operating Zone, for the purposes of allocating ROV
            Standing Charges, the amount of the Scheduled Cable beyond 2,000
            nautical miles shall be considered half its actual length, and this
            added to the cable length within 2,000 nautical miles shall be used
            in calculating L1, L2, and B.

      (ii)  For Scheduled Cables that carry wholly or partially domestic
            traffic, the following formula shall apply for RAU calculation
            purposes:

            Z = Y/2 x X

            Where:

      o     X = Chargeable Sheath Mileage of a Scheduled Cable between landing
            points (after adjustment calculated in accordance with para 2(i)
            above).

      o     Y = The ratio of domestic circuits to all used circuits carried on
            the Scheduled Cable.

      o     Z = The discounted section of the Scheduled Cable.

                                       4
<PAGE>

            X - Z is the cable length to be used in the calculation of L1, L2,
            and B for determining the allocation of ROV Standing Charges.

3.    The attached tables, 'ROV Cost Allocation to Scheduled Cables', show the
      ROV Standing Charge allocation to each Scheduled Cable calculated on the
      basis of (l) and (2) above, and the billing and liability for payment
      parties for each Scheduled Cable. These tables will be amended as
      necessary from time to time.
