THIS IS ANNEXURE "A" REFERRED TO IN THE LEASE BETWEEN NESOVA PTY LIMITED (AS
LESSOR) AND WORLD XCHANGE PTY LIMITED (AS LESSEE) DATED THIS 14th Day of
July, 1997

1.   The provisions of Memorandum Y119929 are deemed to be incorporated
     herein with the following additions and alterations:

     CLAUSE 1 - DEFINITIONS

     1.1      Clause 1.1 is amended by adding the following:

              ""Index Number" means the Consumer Price Index (All Groups) for
              the City of Sydney published from time to time in the
              Commonwealth Statistician's Summary of Australian Statistics.
              If the Commonwealth Statistician updates the reference base of
              the Consumer Price Index (All Groups) for the City of Sydney
              due conversion must be made to preserve the intended continuity
              of calculation by using the appropriate arithmetical factor
              determined by the said Statistician.  If there is any suspension
              or discontinuance of the Consumer Price Index (All Groups) by the
              Commonwealth Authorities "Index Number" means such index
              published at the commencement of the term and at the date of
              suspension or discontinuance of the Consumer Price Index (All
              Groups) in the Commonwealth Statistician's Summary of Australian
              Statistics which reflects fluctuations in the cost of living in
              Sydney and which the parties mutually agree on.  If they are
              unable to agree then "Index Number" means such index chosen by a
              Valuer nominated by the President for the time being of the
              Institute.  Such determination binds the Lessor and the Lessee.
              The cost of such determination will be borne equally by the
              Lessor and the Lessee.

              "Institute" means the Australian Institute of Valuers and Land
              Economists Inc (NSW Division) or such other professional
              organisation which succeeds that body."

              (i)   The Minimum Rent payable for the year immediately preceding
                    the relevant CPI Review Date increased by five per cent
                    (5%); or

              (ii)  The Minimum Rent payable for the year immediately preceding
                    the relevant CPI Review Date multiplied by the Index Number
                    for the quarter ending immediately prior to the relevant
                    CPI Review Date and divided by the Index Number for the
                    quarter ending twelve (12) months prior to the relevant CPI
                    Review Date."

     2.5      Clause 2.5 is amended by deleting the words "the Australian
              Institute of Valuers" and by inserting instead the words "the

                           16 shall be upon terms and conditions required by

                           Lessor upon demand by the Lessor all amounts
                           payable to the Lessor in consequence of the
                           Lessee's failure to duly observe or perform any
                           of such provisions.

                    (c)    If at any time the Lessee fails to duly observe or

                           any loss or damage suffered or which may be suffered
                           by the Lessor by reason of such failure. Any such
                           calling up by the Lessor shall not constitute a
                           waiver of such failure and shall not prejudice any
                           other remedy or right of the Lessor in respect of
                           such failure.

                    (d)    If the bank guarantee is called up by the Lessor
                           in accordance with this clause and this Lease is
                           not terminated by the Lessor the Lessee shall
                           provide to the Lessor a further bank guarantee in
                           the amount so called up (as the case may be) to be
                           held in accordance with this clause.



                                       5

                    (e)    If the Minimum Rent is increased during the term,
                           the Lessee must if requested by the Lessor, provide
                           to the Lessor a further bank guarantee so the
                           amount guaranteed at all time has the same
                           proportion to the Minimum Rent as at the
                           commencement date.

                    (f)    If the Lessor's interest in the premises is
                           assigned or transferred the Lessor shall be at
                           liberty to assign the bank guarantee less all sums
                           called up by it in accordance with this clause to
                           any such assignee or transferee and thereupon the
                           Lessor shall be discharged from all liability to
                           the Lessee or any other person in respect of the
                           bank guarantee.

              16.2  The calling up of the bank guarantee shall not deem the
                    Lessor to condone or waive the Lessee's breach of the
                    Lease and shall be without prejudice to the rights of the
                    Lessor in respect thereof.

              be provided to the Building by Australia Post.  The Lessee
              agrees that it will be the Lessee's responsibility to arrange for
              the collection of its mail from an office of Australia Post or
              if Australia Post has ceased to exist then the postal authority

                               CONSENT TO LEASE

LEASE between NESOVA PTY LIMITED                                  (the LESSOR)

AND WORLD XCHANGE PTY LIMITED                                     (the LESSEE)

OF PREMISES AT Levels 3 & 4, 1 Elizabeth Plaza, North Sydney    (the PREMISES)

AUSTRALIA AND NEW ZEALAND BANKING GROUP LIMITED
ACN 005 357 522 of Level 2, 100 Queen Street, Melbourne             (the BANK)

the proprietor of Mortgage No. 2064791
over the land described in the Certificate of Title

Auto Consol 9590-26

at the request of the parties to the subject Lease CONSENTS to the granting
of the Lease and all other provisions of the Lease subject to these
provisions:

     -        This consent is without prejudice to the right of the Bank to
              exercise its rights under its Mortgage subject to the rights of
              the Lessee under the Lease.

     -        When the Bank exercises its rights under its Mortgage, it has
              all the rights of the Lessor under the Lease:

              -     to enforce observance of all covenants in the Lease
                    relating to the use and occupation of the Premises;

              -     to exercise all rights, powers, privileges, remedies and
                    authorities of the Lessor (including all right of re-entry
                    and all incidental powers); and

              -     to do all acts and grant all consents and licenses to the
                    same extent as if those covenants, provisions, rights,
                    powers, privileges and authorities were given to the Bank.

     -        If the Bank exercises its rights under its Mortgage and gives a
              written notice to the Lessee to pay the rent to it, the Lessee
              must pay all future rents and other moneys payable under the
              Lease to the Bank, who may demand and sue for them if not paid.
              Upon receipt of that notice, the Lease is then deemed to be
              executed by the Lessee and the Bank.

     -        All rights, powers and remedies of the Lessor under the Lease
              are not capable of being enforced by the Lessor without the
              consent in writing of the Bank until that notice is withdrawn
              or the Mortgage is discharged.  Until then the Bank will have
              the same rights and remedies as the Lessor by virtue of the
              Lease, but if the Lessee has any legal or equitable rights of
              set-off against the Lessor, the Lessee cannot enforce them
              against the Bank.

     -        Subject to the Lessee's right of quiet enjoyment of the
              Premises, the Bank will not be liable to observe or perform any
              of the obligations of the Lessor under the Lease unless it
              becomes mortgagee in possesion.



                                       2.

     -        The Lessor and the Lessee must not:

              -     agree to assign or mortgage the Lease, or sublet all or
                    any part of the Premises, or change the use of the Premises;
                    or

              -     vary the terms and conditions of the Lease or any renewal
                    of it without the written consent of the Bank, which it
                    will not withhold unreasonably.

     -        If the Lessee does not observe the terms and conditions of this
              consent, then the Bank's consent to the granting of the Lease may,
              at the option of the Bank, become void and the rights of the Bank
              as mortgagee can be enforced without reference to the Lease.

     -        Any statutory form of consent by the Bank is given without
              prejudice to these conditions.

              THE BANK AGREES that while the Lessee is not in default under
              the Lease it will not interfere with the Lessee's use or
              occupation of the Premises even though the Lessor is in default
              under the Mortgage.

              THE LESSOR AND THE LESSEE accept these conditions.
