             amendments as set out in Annexure 15 only unless the Tenant shall
             otherwise approve an amendment (such approval not to be
             unreasonably withheld). If approval shall not have been given or

            period of delay and any resulting delays to the Base Building Works
            properly attributable thereto shall be a Tenant's Delay for the

            Agreement by reason of Force Majeure and/or Tenant's Delay and/or
            any delays consequential thereon then the Developer shall notify the

            event of dispute) is determined by an Independent Person acting as
            an expert in accordance with Clause 30.5 each such extension of time
            shall be granted to the Developer and all the dates and periods in
            this Agreement which are expressed to be extendable by reason of
            such delay shall be treated as deferred (or further deferred if
            extensions of time have already been granted) by such agreed or
            determined extension of time and, for the avoidance of doubt, if the
            Developer fails to comply with its obligations to achieve the
            matters the subject of this Agreement by the date specified in this
            Agreement referable to such matters but would have so complied but
            for Tenant's Delay and/or Force Majeure, then for the purposes of

                 the Base Building Works

            (c)  the Base Building Definition

            (d)  the terms of this Agreement

7.1  Base Building Works Finishes Design Development

                                      -20-


     The Developer shall within the relevant time limits specified in the
     Critical Dates Schedule submit to the Tenant architectural and engineering
     working drawings and specifications (as appropriate) prepared by the
     relevant Consultant or Key Consultant or any other party detailing Design
     Development of the Base Building Works Finishes from the stage shown on the
     Base Building Plans listed in the drawings schedule annexed to this
     Agreement as Annexure 4 in sufficient detail to enable the Tenant properly
     to assess and consider the Design Development being proposed. The Developer
     shall have regard to (but shall not be bound by) any reasonable
     representations made by the Tenant with regard to the Design Development of
     Base Building Works Finishes

7.2  Permitted Variations

     7.2.1  On giving the Tenant prior written notice (which may be by the
            provision of drawings) the Developer shall be entitled to make
            alterations, additions or variations to the Base Building Works
            without the Tenant's consent where:-

            (a)  such are lawfully required after the commencement of the Base
                 Building Works in order to comply with Statutory Requirements;
                 or

            (b)  any materials specified in the specifications relating to the
                 Base Building Works are in short supply or are or become
                 unobtainable or continuous supply thereof cannot be reasonably
                 expected guaranteed or are subject to delay and if awaited
                 would demonstrably impede the progress of the Base Building
                 Works (in which event the Developer may use alternative
                 materials of a similar nature, type, character, design and of
                 no lesser quality to those specified in the specification
                 forming part of the Base Building Definition); or

            (c)  the same will not materially adversely affect the Tenant's
                 beneficial use and enjoyment of the Demised Premises as offices
                 and do not relate to the Base Building Works Finishes; or

            (d)  the same constitute Design Development

     7.2.2  The Developer shall be entitled to make alterations, additions or
            variations to the Base Building Works with the Tenant's approval
            (such approval not to be unreasonably withheld) where the same
            relate to the Base Building Works Finishes or do not otherwise fall
            within Clause 7.2.1

     7.2.3  If within a period of six (6) Working Days following receipt by the
            Tenant of a written notice from the Developer requesting the Tenant
            to consent to an alteration, variation or amendment or the details
            of the same pursuant to Clause 7.2.2 (such request being accompanied
            by such technical drawings and information as are available and the
            Tenant shall reasonably require in order to evaluate the request)
            the Tenant has not in writing approved or reasonably objected to any
            such alterations, additions or variations or objected to the details
            of them giving its reasons or requested such further technical
            drawings and information as it may reasonably require in order to
            evaluate the request then consent shall be deemed to have been given
            by the Tenant

     7.2.4  The Developer shall as soon as reasonably practicable and in advance
            where possible supply to the Tenant details of any such alterations,
            additions or variations as are referred to in this Clause 7 (whether
            or not the Tenant's approval is required

                                      -21-


            or given to such) together with copies of any plans drawings and
            specifications relating to them

     7.2.5  If the Tenant makes a written objection following a request for
            consent pursuant to the provisions of Clause 7.2.2 such written
            objection shall specify in reasonable detail the grounds for such
            objection and in the event of dispute as to whether or not the
            Tenant is acting reasonably in objecting then either party may refer
            the matter to the Independent Person acting as an expert pursuant to
            the provisions of Clause 30.5

8.   TENANT'S REQUESTED MODIFICATIONS

8.1  Tenant's notification of Modifications

     8.1.1  The Tenant shall be entitled in accordance with the provisions of
            this Clause 8 and subject to clauses 8.1.2 and 8.1.3 and subject to
            the request being practicable to implement at the time of the
            request and subject to compliance with Clause 8.2, at the Tenant's
            sole cost and expense and by application in writing to request the
            Developer to approve (such approval not to be unreasonably withheld)
            additions and/or substitutions to the Base Building Works (in each
            case a "Tenant's Requested Modification"). In the event that there
            is disagreement between the parties as to whether this Clause 8.1
            applies either party may apply for the matter to be determined by an
            Independent Person acting as an expert pursuant to Clause 30.5

     8.1.2  The Tenant shall only be entitled to request a Tenant's Requested
            Modification within six (6) months before the Target Date:-

            (a)  which is not reasonably likely to cause delay to the Base
                 Building Works; or

            (b)  which is reasonably likely to cause delay to the Base Building
                 Works which relate to the Demised Premises but which is capable
                 of being disregarded for the purposes of issuing the Base
                 Building Works Practical Completion Certificate

     8.1.3  The Tenant shall not be entitled to request a Tenant's Requested
            Modification within six (6) months before the Target Date:-

            (a)  which in the Developer's opinion is likely to cause delay to
                 any part of the Base Building Works which do not relate to the
                 Demised Premises; or

            (b)  where in the Developer's opinion the requested additions and/or
                 substitutions to the Base Building Works are likely to render
                 the issue of the Base Building Works Practical Completion
                 Certificate impracticable

8.2  Restrictions on Proposals

     Tenant's Requested Modifications shall not contain facilities, materials or
     work which, if implemented (when looked at together with any previously
     requested Tenant's Requested Modifications including those requested but
     not yet agreed and taking into account any payments made or to be made
     between the parties pursuant to this Clause 8), would:-

     8.2.1  alter the exterior (including the appearance) of the Building except
            the roof; or

                                      -22-


     8.2.2   materially alter the roof of the Building; or

     8.2.3   adversely affect the structural integrity of the Building; or

     8.2.4   reduce the lettable area of the Demised Premises (other than to an
             immaterial extent); or

     8.2.5   reduce the lettable area of the Building; or

     8.2.6   reduce the open market value or open market rent of the Building
             otherwise than by reducing its lettable area; or

     8.2.7   negate or adversely affect the validity or enforceability of or the
             availability or quantum of remedies or damages under any
             appointment contract or warranty entered into by any Key Consultant
             or any Consultant or any Trade Contractor (unless the Key
             Consultant or Consultant or Trade Contractor agrees otherwise); or

     8.2.8   place (or prospectively place) the Developer in breach of its
             obligations to any third parties; or

     8.2.9   be incompatible with any of the Base Building Works already carried
             out or to be carried out by the Developer; or

     8.2.10  be such as are intended to form any part of the MSDF Works (or
             works of that type) or any part of the Tenant's Works provided that
             this shall not exclude alterations to the Base Building Works in
             order to facilitate the Tenant's Works; or

     8.2.11  adversely affect the usage or the functioning of the Building
             Systems or the cost of operating the Building Systems; or

     8.2.12  violate any laws or (subject to the provisions of clause 8.6.4) the
             requirements of any Approvals or the requirements from time to time
             of any insurers or be such that any Approval or any insurance
             effected or to be effected by the Developer pursuant to Clause 21
             is reasonably likely to be unobtainable or is adversely affected;
             or

     8.2.13  in the Developer's reasonable judgement not be reasonably capable
             of being reinstated at the end or sooner determination of the
             contractual term of the Lease (if such reinstatement is required in
             accordance with Clause 8.4.1(e)); or

     8.2.14  involve the carrying out of works or the installation of items
             which in the Developer's reasonable opinion are relatively untried
             and untested and which in the Developer's reasonable opinion
             increase (otherwise than to an immaterial extent) the risks
             accepted by the Developer concerning defective works; or

     8.2.15  prevent or be likely to prevent any supply or supplies made
             pursuant to the grant of the Lease pursuant to this Agreement being
             treated as an exempt supply or supplies of land under Group 1 of
             Schedule 9 to the Value Added Tax Act 1994; or

     8.2.16  cause or be likely to cause a Tenant's Delay which (when taken
             together with any other Tenant's Delays which have already occurred
             or which are reasonably foreseeable) would exceed 120 days in the
             aggregate

     Any dispute as to whether a Tenant's Requested Modification is prohibited
     by this Clause 8.2 or whether the Developer is reasonably withholding
     consent pursuant to Clause 8.1 or this

                                      -23-


     Clause 8.2 shall be agreed between the Developer and the Tenant or in the
     event they cannot so agree determined by the Independent Person acting as
     an expert in accordance with Clause 30.5

8.3  Approval of Modifications

     The Tenant shall furnish with any such application (a "TRM Application")
     the reasons for it and sufficient information to enable the Developer
     (acting reasonably) to determine the extent and scope of the Tenant's
     Requested Modifications, the cost of the same, any proposed changes to
     lettable area, any anticipated impact on the construction programme, the
     letting, running or management of the Building or any part of it or the
     Developer's interest in it. The Developer shall not be obliged, where it
     has given initial consideration to a TRM application but has found that any
     such reasons and/or information as referred to above have not been provided
     or the Developer reasonably requires other information, to give further
     consideration to the TRM application until the Tenant has (following
     written request from the Developer identifying the missing further
     information that is required such request to be given within five (5)
     Working Days of receipt of the TRM Application) provided that further
     information which the Developer reasonably requires

8.4  Authorisation Requests and Estimates

     8.4.1  As soon as reasonably practicable following receipt of the
            information specified in Clause 8.3 and (subject as set out in
            Clauses 8.1 and 8.2) if the Developer approves a TRM Application the
            Developer shall as soon as reasonably practicable work closely with
            the relevant Tenant's Consultant (and, in particular, the Tenant's
            Quantity Surveyors) and shall furnish to the Tenant in duplicate a
            memorandum which sets out details of the Tenant's Requested
            Modification in question, the duplicate of which will include an
            acceptance section for completion by the Tenant if it wishes to
            proceed with such Tenant's Requested Modification (the "TRM
            Authorisation Request") and to which is annexed a statement setting
            out:-

            (a)  the Approvals and the third party consents required in respect
                 of the Tenant's Requested Modification (the "Modification
                 Consents")

            (b)  an estimate of any Tenant's Delay which is likely to result by
                 reason of such Tenant's Requested Modification and which shall
                 include any estimated period of delay in respect of seeking and
                 obtaining the Modification Consents ("Estimate of Tenant's
                 Delay") and in the case of a Tenant's Requested Modification
                 requested within six (6) months before the Target Date an
                 estimate of the likely delay to the Base Building Works
                 Practical Completion and whether it is likely to render the
                 issue of the Base Building Works Practical Completion
                 Certificate impracticable

            (c)  a statement (the "Costs Estimate") setting out in reasonable
                 detail the Developer's good faith estimate of the Modification
                 Costs in relation to such Tenant's Requested Modification

            (d)  in the case of substitutions to the Base Building Works the
                 Unspent Costs attributable to the substitution (the "Estimated
                 Unspent Costs")

            (e)  whether the Developer (acting reasonably) will require
                 reinstatement of the Tenant's Requested Modification at the end
                 or sooner determination of the term of the Lease (the
                 "Reinstatement TRM's")

                                      -24-


                 Provided That the Estimate of Tenant's Delay, the Costs
                 Estimate, and the Estimated Unspent Costs (the "Relevant
                 Estimates") shall not be binding on the Developer or the Tenant
                 and no warranty as to the accuracy of such statements is given
                 or shall be implied

     8.4.2  Prior to receiving the Tenant's countersigned TRM Authorisation
            Request and Relevant Estimates the Developer shall continue to
            progress or procure the progress of the Base Building Works as if no
            application for a Tenant's Requested Modification had been received

8.5  Acceptance by the Tenant

     8.5.1  If, having received the TRM Authorisation Request and the Relevant
            Estimates provided by the Developer pursuant to Clause 8.4.1, the
            Tenant wishes to have the Tenant's Requested Modification made it
            shall within six (6) Working Days after receipt of such TRM
            Authorisation Request and Relevant Estimates countersign (by way of
            acknowledgement) and return the duly countersigned duplicate
            (without amendment or qualification) of the TRM Authorisation
            Request to the Developer

     8.5.2  The countersigning and returning of the duplicate TRM Authorisation
            Request unamended and unqualified by the Tenant authorises the
            Developer to proceed with or procure that CWCL proceeds with the
            Tenant's Requested Modification and confirms that the actual
            Modification Costs referable to the Tenant's Requested Modification
            incurred by the Developer and/or CWCL whether or not in excess of
            those set out in the Costs Estimate shall (inter alia) constitute
            Modification Costs for the purposes of this Agreement and that the
            Tenant shall be responsible for all the consequences of any actual
            resulting period of Tenant's Delay whether or not in excess of the
            Estimate of Tenant's Delay and shall have the benefit of any actual
            Unspent Costs referable to the Tenant's Requested Modification in
            question

8.6  Preparation of plans

     If the Tenant has countersigned and returned a TRM Authorisation Request
     unamended and unqualified to the Developer then:-

     8.6.1  The Developer shall, subject to Clause 8.6.2, prepare or procure the
            preparation of scaled and dimensioned architectural and engineering
            working drawings and specifications showing in detail and in scope
            the Tenant's Requested Modification which drawings and
            specifications are in this Agreement together called "Modification
            Plans" Provided That if it is apparent that a Modification Consent
            is required the Developer shall first prepare or procure the
            preparation of the plans which are necessary in order to apply for
            the Modification Consent and only prepare or procure the preparation
            of full Modification Plans either when the Modification Consent has
            been obtained or, if earlier, when the parties agree (acting
            reasonably) that it is appropriate to do so

     8.6.2  The Tenant shall bear the proper costs and expenses incurred by the
            Developer and/or CWCL in preparation of the Modification Plans and
            the plans necessary to apply for the Modification Consent

     8.6.3  Any facilities or materials supplied by and any work performed or
            procured by the Developer by reason of Tenant's Requested
            Modification which are described in the Modification Plans are
            called "Modifications" in this Agreement and shall be deemed to be
            part of the Base Building Works

                                      -25-


     8.6.4  At the request of the Tenant the Developer shall at the Tenant's
            cost and expense seek and use its best endeavours to obtain the
            Modification Consents and shall notify the Tenant whether the same
            have been granted or otherwise forthwith on receiving notification
            of the same

     8.6.5  If the Modification Consents are refused the Tenant's request for
            the Tenant's Requested Modification shall be deemed to be withdrawn
            and the provisions of Clause 8.9 shall apply

     8.6.6  Subject to the Tenant having received copies of the Modification
            Consents, the Tenant shall notify the Developer within six (6)
            Working Days of their receipt by the Tenant whether the Modification
            Consents are satisfactory to it and if they are the provisions of
            Clause 8.8 shall apply and if they are not or if the Tenant shall
            fail to give such notice within such period the Tenant's request for
            the Tenant's Requested Modification shall be deemed to be withdrawn
            and the provisions of Clause 8.9 shall apply

     8.6.7  Any delay to the Base Building Works resulting from the need for and
            the obtaining of Modification Consents shall be a Tenant's Delay for
            the purposes of this Agreement

8.7  Calculation of actual Modification Costs referable to Tenant's Requested
     Modifications and Unspent Costs

     8.7.1  The Developer shall calculate the amount of the actual Modification
            Costs referable to the Modifications utilising (inter alia)
            initially for estimation purposes the pricing information provided
            by each Trade Contractor appointed or to be appointed in respect of
            the relevant element of the Base Building Works and eventually
            utilising (inter alia) the sums finally payable to Trade Contractors
            in relation to the relevant Tenant's Requested Modifications

              Base Building Works Practical Completion Certificate when issued
              and this may be issued by the Developer subject to a list of
              Snagging Items

      19.1.3  If the Tenant disputes the correctness of the Base Building Works
              Practical Completion Certificate or maintains that the Base
              Building Works were not practically complete at the date of the
              Base Building Works Practical Completion Certificate (subject as
              set out in Clause 19.1.2) the Tenant may serve a Counter-Notice
              (the "Counter-Notice") in writing upon the Developer within five
              (5) Working Days after the receipt by the Tenant of the Base
              Building Works Practical Completion Certificate specifying the
              respects in which in the opinion of the Tenant the Base Building
              Works have not been practically completed as aforesaid or in which
              it is contended that the Base Building Works Practical Completion
              Certificate is incorrect and giving such written reasons as can be
              given at that time for any contentions to the Developer and
              attaching copies of all notes, reports, memoranda or other matters
              in the possession of or available to the Tenant and which are
              relevant to its contentions. If the Tenant fails to serve such a
              Counter-Notice within the said five (5) Working Day period the
              Tenant shall be deemed to have accepted the relevant Certificate
              which shall be final and binding for the purposes of this
              Agreement

      19.1.4  The Developer may accept a Counter-Notice from the Tenant but if
              the Developer (by notice in writing to the Tenant within five (5)
              Working Days after the Counter-Notice) disputes the correctness of
              the Tenant's Counter-Notice the dispute shall be referred for
              determination by an Independent Person acting as an expert in
              accordance with Clause 30.5 to determine whether the Base Building
              Works have been practically completed or whether the Base Building
              Works Practical Completion Certificate is correct or the Base
              Building Works were not practically complete at the date of the
              Base Building Works Practical Completion Certificate and, if not,
              what works still remain to be carried out in order to achieve Base
              Building Works Practical Completion or what steps are necessary to
              correct the Base Building Works Practical Completion Certificate

      19.1.5  If the Independent Person (taking account of Clause 19.1.2)
              determines that there is work remaining to be carried out as set
              out in Clause 19.1.4 he shall specify such work and the Developer
              shall procure the same to be carried out as soon as reasonably
              practicable to the reasonable satisfaction of the Independent
              Person who shall thereupon certify the date upon which such work
              was completed to his

                                      -40-


              reasonable satisfaction and the date so certified shall be the
              date upon which Base Building Works Practical Completion shall be
              deemed to have taken place for the purposes of this Agreement and
              the Base Building Works Practical Completion Certificate validly
              issued

      19.1.6  If the Independent Person determines that the Base Building Works
              Practical Completion Certificate is incorrect then he shall
              specify the errors which were made in issuing the Base Building
              Works Practical Completion Certificate and the Developer shall
              ensure that such errors are corrected as soon as reasonably
              practicable to the satisfaction of the Independent Person who
              shall thereupon certify the date upon which in his opinion the
              Base Building Works Practical Completion Certificate would have
              been validly issued and subject to Clause 19.3 such date shall be
              the date upon which Base Building Works Practical Completion is
              deemed to have taken place for the purposes of this Agreement and
              the Base Building Works Practical Completion Certificate treated
              as issued

19.2  Tenant's Works Practical Completion

      The Tenant will notify the Developer promptly of Practical Completion of
      the Tenant's Works and promptly provide a copy of the relevant certificate
      and an opportunity to inspect as soon as practicable following the issue
      of such certificate

19.3  Tenant's Delay

      The Developer shall give notice to the Tenant certifying the dates on
      which the Base Building Works Practical Completion Certificate would have
      been issued but for Tenant's Delay taking into account all periods of
      Tenant's Delay and all extensions of time already agreed or determined in
      respect of Tenant's Delay pursuant to Clause 5.4.3 and the other
      provisions of this Agreement each applied in accordance with the
      definition of Tenant's Delay ("Delay Notice"). In the event that the
      Tenant disputes the date referred to in such certificate within six (6)
      Working Days (failing which the Tenant shall be deemed to have accepted
      the relevant Delay Notice which shall be final and binding for the
      purposes of this Agreement) the matter shall be referred to an Independent
      Person acting as an expert in accordance with Clause 30.5. If the
      Independent Person determines that the Tenant's Delay Notice is incorrect
      then he shall certify the date upon which he considers the Base Building
      Works Practical Completion Certificate would have been issued but for
      Tenant's Delay taking account of all extensions of time already agreed or
      determined in respect of Tenant's Delay pursuant to Clause 5.4.3 and the
      other provisions of this Agreement

19.4  Damage caused by Tenant

      For the avoidance of doubt and notwithstanding that any Certificate may be
      issued subject to Snagging Items any damage caused to the Base Building
      Works by the Tenant or the Tenant's Contractors or anyone under their
      respective control shall be ignored and deemed to have been made good for
      the purposes of certifying Base Building Works Practical Completion

                                      -41-

      of the same from the Tenant) procure to be remedied and made good to the
      reasonable satisfaction of the Tenant all Defects in the Base Building
      Works and the Tenant shall give notice to the Developer as soon as

               voidable wholly or in part nor (unless the Tenant has previously
               notified the Developer and agreed to pay the increased premium)

      Tenant shall apply all monies received from such insurance (insofar as the
      same shall extend) in making good the loss or damage in respect of which
      the same shall have been received
