     required or permitted pursuant to this Agreement or pursuant to an
     Integration Committee minute approving such action:

(a)  unless the Buyer's representatives on the Integration Committee agree

4.2  Pyrmont Property Lease

(a)  BT Pty Ltd undertakes that it will, in conjunction with the Buyer, use all
     reasonable endeavours from the date of this Agreement to achieve an
     assignment to the Buyer of BT Pty Ltd's interest in the Pyrmont Property
     Lease (in respect of Level 4 and half of Level 3 only) on terms equal to
     the Buyer paying AU$264,506 per annum with a yearly increase of the higher
     of 4% or CPI, exclusive of outgoings and payments under the Car Park
     Licence. If it becomes apparent to the Parties that despite their
     reasonable efforts the landlord under the Pyrmont Property Lease (Landlord)
     is not prepared to consent to an assignment of the Pyrmont Property Lease,
     then in any such case BT Pty Ltd and the Buyer will use all reasonable
     endeavours to achieve a sub-letting to the Buyer on terms substantially
     equivalent to BT Pty Ltd's Pyrmont Property Lease of BT Pty Ltd's interest
     in the Pyrmont Property Lease (in respect of Level 4 and half of Level 3
     only).

(b)  BT Pty Ltd acknowledges that its reasonable efforts for the purposes of
     this clause 4.2 include the following:

     (i)  in the case of an assignment: BT Pty Ltd undertaking to the Landlord
          to place in escrow on the granting of the licence to assign, a sum
          equivalent to the Net Present Value of the amounts payable under the
          Pyrmont Property Lease for the period from Completion until 31
          December 2006, less an amount equal to AU$264,506 per annum with a
          yearly increase of the higher of 4% or CPI, exclusive of outgoings and
          payments under the Car Park Licence; or

     (ii) in the case of a sub-letting to the Buyer: BT Pty Ltd giving to the
          Buyer a sum worked out by multiplying $38,113 per month by the number
          of months from the Completion Date to 31 December 2006 (for example,
          assuming Completion on 31 May 2002, such sum would be $2,096,240).

4.3  Access to information

The Sellers must:

(a)  allow the Buyer and its agents, representatives and advisers reasonable
     access to the Property, the Business Assets, the books and records
     (including to take copies of such material) and the Employees of the
     Sellers upon reasonable prior notice; and

                                     Page 5

<PAGE>

(b)  ensure the Buyer is kept promptly informed of all material matters relating
     to the businesses, assets and affairs of the Sellers and further that the
     Buyer receives a copy of all board papers, management reports and accounts,
     and Integration Committee minutes as soon as practicable but no later than
     such time when they are received by the Sellers.

4.4  Integration Committee

The Buyer and BT Pty Ltd shall each appoint in writing 3 representatives to an
Integration Committee for the purpose of monitoring and advising on the
operation of the Business by the Sellers prior to the Completion Date and the
performance of the Buyer and the Sellers of their respective obligations
pursuant to this Agreement. In the event of deadlock of any meeting of the
Integration Committee, the parties agree that Bijan Khezri shall have the final
and casting vote.

4.5  The Buyer's Conduct

Unless BT Pty Ltd agree otherwise in writing, prior to Completion the Buyer must
not do anything, fail to do anything, or allow anything to happen which would
make a Buyer Warranty false or misleading in a material respect. During the
period from signing this Agreement until Completion, the Buyer must not do
anything which would make a Seller Warranty false or misleading in a material
respect, provided that this provision will not restrict the Buyer from operating
the Buyer's own business on a normal commercial basis.

4.6  HIC Agreement

(a)  BT Pty Ltd will use reasonable endeavours:

     (i)  to remedy to HIC's satisfaction defects or deficiencies alleged by HIC
          in products or services supplied by BT Pty Ltd to the Health Insurance
          Commission (HIC) pursuant to the agreement between HIC and BT Pty Ltd
          dated 1 February 2000 (the HIC Agreement); and

     (ii) to secure consent by HIC to assignment of the HIC Agreement from BT
          Pty Ltd to the Buyer with effect on and from Completion, but varied in
          accordance with the draft letter from Rory Brennan of BT Pty Ltd to
          Kathy Kirby of HIC which is Attachment J to the "Disclosure Bundle"
          attached to the Disclosure Letter (Agreed HIC Amendments), or
          substantially similar terms or as otherwise agreed by the parties.

(b)  Not less than five (5) days prior to Completion the Buyer will advise the
     Sellers whether the Buyer nominates the HIC Agreement as an Excluded
     Contract. If the Buyer does not so nominate, the HIC Agreement will be a
     Customer Contract and governed as such by other provisions of this
     Agreement. If the Buyer does so nominate:

                                     Page 6

<PAGE>

     (i)  the HIC Agreement will be an Excluded Contract as though included in
          Part 2 of Schedule 1 and governed as such by other provisions of this
          agreement which relate to Excluded Contracts;

     (ii) BT Pty Ltd must and, subject to paragraph (iii), will require Buyer
          to, and Buyer will, provide professional services at the same rates as
          are payable by HIC to BT Pty Ltd under the HIC Agreement, to
          facilitate BT Pty Ltd to provide support services to HIC as required
          under the HIC Agreement and otherwise as reasonably required to enable
          BT Pty Ltd to fulfil its ongoing support obligations to HIC (other
          than Level 3 support) subsequent to Completion on the same terms as
          apply generally to provision of professional services by the Buyer to
          BT plc;

     (iii) if the Buyer does not provide professional services as referred to in
          paragraph (ii) in accordance with the terms as apply generally to
          provision of professional services by the Buyer to BT plc and
          otherwise as reasonably required to enable BT Pty Ltd to fulfil its
          ongoing support obligations to HIC (other than Level 3 support)
          subsequent to Completion and the Buyer does not remedy that deficiency
          within 10 days from the date of any notice from BT Pty Ltd to the
          Buyer specifying that deficiency, then notwithstanding clause 2.1 of
          the Distribution Agreement and without affecting BT Pty Ltd's other
          rights and remedies, BT Pty Ltd will be entitled to itself provide or
          to purchase support services from another provider in order to fulfil
          BT Pty Ltd's obligations under the HIC Agreement.

(c)  If at any time subsequent to Completion BT Pty Ltd is able to:

     (i)  remedy to HIC's satisfaction defects or deficiencies alleged by HIC in
          products or services supplied by BT Pty Ltd to HIC pursuant to the HIC
          Agreement; and

     (ii) secure consent by HIC to assignment of the HIC Agreement from BT Pty
          Ltd to the Buyer varied in accordance with the Agreed HIC Amendments
          or substantially similar terms or as otherwise agreed by the parties,

     BT Pty Ltd must notify the Buyer, providing reasonable evidence of
     fulfilment of (i) and (ii) above. If BT Pty Ltd is able to do so, the Buyer
     will consent to an assignment of the HIC Agreement subject to the Agreed
     HIC Amendments, and the provisions of clause 7 of this Agreement will
     operate as and from the date that this assignment takes effect, amended
     however such that where provisions of clause 7 refer to Completion and the
     Completion Date, those references will be read as references to the
     assignment pursuant to this provision and the date that that assignment
     takes effect.

                                     Page 7

<PAGE>

(d)  At any time subsequent to Completion and notwithstanding that BT Pty Ltd is
     not able to fulfil the conditions stated in (i) and (ii) of paragraph (c)
     above, the Buyer may, at Buyer's election exercised on not less than 20
     Business Days prior notice, require BT Pty Ltd to assign the HIC Agreement,
     on reasonable terms and subject to such assignment being in accordance with
     provisions of the HIC Agreement, in which event the provisions of clause 7
     of this Agreement will operate as and from the date that this assignment
     takes effect, amended however such that where provisions of clause 7 refer
     to Completion and the Completion Date, those references will be read as
     references to the assignment pursuant to this provision and the date that
     that assignment takes effect.

(e)  The provisions of this clause 4.6 survive Completion of this Agreement and
     will continue for such period as is required to give effect to these
     provisions in accordance with their tenor.

          reductions in the Purchase Price; and

     and the Buyer. The net adjustment amount (Adjustment Amount) determined in
     accordance with the Adjustment Statement will be an amount payable by the
     Sellers to the Buyer, or by the Buyer to the Sellers, as the case may be.
     The Adjustment Amount must be paid in accordance with clause 6.9 on the
     Adjustment Date.

(b)  During the Adjustment Period, the Buyer and the Sellers shall use all

     preparing the calculation of the Adjustment Statement at the Completion
     Date.

(e)  If the Buyer and the Sellers do not agree on a value or a particular item
     in the calculation of the Adjustment Statement upon the expiry of the
     Adjustment Period, the value or particular item is to be determined by an
     Independent Expert in accordance with clause 5.2.

(f)  For the purpose of calculating any increase to the Purchase Price under
     clause 5.1(a), the Work in Progress shall be calculated on a GST exclusive
     basis and Seller Prepayments shall be reduced by the amount of any Input
     Tax Credits for which the Seller is entitled in respect of those Seller
     Prepayments.

5.2  Independent Expert

(a)  valuation: If a matter is referred to the Independent Expert under clause
     5.1, the parties must immediately upon the expiry of the Adjustment Period
     instruct the Independent Expert to complete the relevant determination as
     soon as possible and no later than 28 days following the expiry of the
     Adjustment Period.

(b)  access and submissions: Each party:

     (i)  must provide the Independent Expert with full access to its books and
