              of the Company to Newco prior to the expiration of the 2 year
              period following the Completion Date only if:

              (i)   the Purchaser will directly own the whole of the issued

              expiration of the two year period following the Completion Date
              if:

              (i)   the provision in Clause 8.7.1(i) is satisfied;

              (ii)  Newco does not or will not make an election pursuant to 
                    Section 301.7701-3 of US Treasury Regulations to treat
                    Newcosub as an association taxable as a corporation, and
                    Newco makes a timely election pursuant to Section 301.7701-3
                    of US Treasury Regulations to treat Newcosub as an entity
                    disregarded as separate from Newco effective from the date
                    of incorporation of Newcosub;

              (iii) Newco directly owns or will own the whole of the issued 
                    share capital of Newcosub throughout the period beginning on

       8.7.3  the Purchaser or Newco may transfer the whole of the issued share
              capital of the Company to any person provided that the Purchaser
              obtains, prior to such transfer, either a ruling from the U.S.

              tax counsel to the Purchaser, addressed to the Vendors,
              concluding, that such transfer will not the cause the Purchaser's

               concerning the foregoing matters shall, subject to the
               requirements of law or any regulatory body or the rules and

9.4  Successors and Assigns

              to it. Accordingly, neither the Purchaser nor the Vendors nor the
              Company may, without the prior written consent of the others,
              assign the benefit of all or any of the others' obligations under
              this Agreement, nor any benefit arising under or out of this
              Agreement.

       9.4.2  Except as otherwise expressly provided in this Agreement, the

              assign to a connected company the benefit of all or any of the
              Vendors' obligations under this Agreement provided that such
              assignment shall not be absolute but shall be expressed to have
              effect only for so long as the assignee remains a connected
              company. For the purposes of this sub-clause a connected company
              is a company which is a wholly-owned subsidiary of the party
              concerned or which is a holding company of such party or a

period originally fixed or any time, date or period so extended time shall be of
the essence.

9.7  Further Assurance

The Vendors severally agree with the Purchaser that, at any time after the date
of this Agreement, they shall and shall use their reasonable best endeavours to

reasonably require for the purpose of giving to the Purchaser the full benefit
of all the provisions of this Agreement.

9.8  Interest

If the Vendors or the Purchaser default in the payment when due of any sum
payable under this Agreement (whether determined by agreement or pursuant to an
order of a court or otherwise) the liability of the Vendors or the Purchaser (as
the case may be) shall be increased to include interest on such sum from the
date when such payment is due until the date of actual payment (as well after as
before judgment) at a rate per annum of 2 per cent. above the base rate from
time to time of Lloyds Bank PLC. Such interest shall accrue from day to day.

1.   Shelf Registration and Listing

1.1  The Purchaser shall prepare and file with the United States Securities and
     Exchange Commission (the "SEC"), as promptly as practicable after the
     Completion Date (but in no event later than the date which is 30 calendar
     days after the Completion), a registration statement pursuant to Rule 415
     under the Securities Act covering all of the Consideration Shares to be
     issued pursuant to this Agreement (the "Purchaser Registration Statement".
     The Purchaser Registration Statement shall be on Form S-3 or another
     appropriate form permitting registration of the Consideration Shares for
     resale by the Vendors. The Purchaser shall not permit any securities to be
     included in the Purchaser Registration Statement other than the
     Consideration Shares to be issued pursuant to this Agreement. The Purchaser
     shall use its reasonable best efforts to cause the Purchaser Registration
     Statement to be declared effective pursuant to the Securities Act as soon
     as practicable after the filing thereof and to keep the Purchaser
     Registration Statement continuously effective under the Securities Act
     until the earlier of (i) the date which is 24 months following the
     Completion Date, (ii) the date that all Consideration Shares covered by the
     Purchaser Registration Statement have been sold in the manner set forth and
     as contemplated in the Purchaser Registration Statement or (iii) the date
     on which each Vendor could sell all of its Consideration Shares issued
     pursuant to this Agreement at one time pursuant to Rule 144 (other than
     Rule 144(k)) promulgated under the Securities Act (the "Effectiveness
     Period"). Each Vendor shall notify Purchaser in writing of the date that
     all of its Consideration Shares have been sold in the manner set forth and
     as contemplated in the Purchaser Registration Statement.

1.2  The Purchaser shall use its reasonable best efforts to keep the Purchaser
     Registration Statement continuously effective during the Effectiveness
     Period by supplementing and amending the Purchaser Registration Statement
     if required by the rules, regulations or instructions applicable to the
     registration form used for such Purchaser Registration Statement. In the
     event of an issuance of any stop order suspending the effectiveness of the
     Purchaser Registration Statement, or any order suspending or preventing the
     use of any related prospectus or suspending the qualification of the
     Consideration Shares included in such Purchaser Registration Statement for
     sale in any jurisdiction, the Purchaser will use its reasonable best
     efforts promptly to obtain the withdrawal of such order. In the event of
     the issuance of any such stop order, the Effectiveness Period (if
     calculated under Section 1.1(i)) will be extended by the number of days
     such stop order is in effect.

1.3  The Purchaser may suspend sales under the Purchaser Registration Statement
     or defer the updating of the Purchaser Registration Statement and suspend
     sales thereunder for a reasonable period of time (not exceeding 60 days) if
     the Purchaser furnishes the Vendors (with such notice to be sent to the
     Vendors Representative in the case of the Remaining Vendors) with a notice
     signed by an executive officer of the Purchaser (a "Suspension Notice")
     stating that, in its good faith judgment, the Purchaser has determined that
     maintaining the effectiveness of the Purchaser Registration Statement and
     permitting offers and sales thereunder would require the Purchaser to make
     public disclosure of information not otherwise required to be publicly
     disclosed at such time, the public disclosure of which would have Material
     Adverse Effect upon the Purchaser or would adversely affect the ability of
     the Purchaser to consummate a material financing, acquisition, disposition
     of assets or stock, merger or other comparable transaction. Upon the
     receipt of any such notice from the Purchaser, each Vendor agrees to
     discontinue disposition of Consideration Shares pursuant to the Purchaser
     Registration Statement (a "Black Out") until the earlier of (i) such time
     as such Vendor receives copies of a supplemental or amended prospectus,
     (ii) such time as such Vendor receives notification from the Purchaser that
     such suspension is no longer required or (iii) 60 days, provided, that the 
     Purchaser may not suspend sales for more than aggregate of 90 days in any
     twelve-month period.

                                      -47-

 

     In the event the Purchaser shall give a Suspension Notice, the
     Effectiveness Period will be extended by the number of days during the time
     period from and including the date of the giving of such Suspension Notice
     to and including the date when the Black-Out shall have terminated in
     accordance with the immediately preceding paragraph.

2.   Registration Procedures.

     In any offering hereunder, the Purchaser shall:

2.1  Before filing the Purchaser Registration Statement, any prospectus
     supplement or any pre- or post-effective amendment to the Purchaser
     Registration Statement in connection with the offering of Consideration
     Shares, the Purchaser will furnish to the Vendors Representative copies of
     all such documents proposed to be filed and a reasonable opportunity to
     comment thereon.

2.2  Subject to Section 2.1 above, prepare and file such post-effective
     amendments to the Purchaser Registration Statement as may be necessary to
     keep it continuously effective for the Effective Period (including any
     extensions thereof in accordance with Section 1.3); cause the related
     prospectus to be supplemented by any required prospectus supplement, and as
     so supplemented to be filed pursuant to Rule 424 (or any similar provisions
     then in force) under the Securities Act; and comply with the provisions of
     the Securities Act with respect to the disposition of all securities
     covered by the Purchaser Registration Statement during the applicable
     period in accordance with the intended methods of disposition by the
     sellers thereof set forth in such prospectus as so supplemented.

2.3  Notify the selling holders promptly, and (if required by any such person)
     confirm such notice in writing, (i) when the Purchaser Registration
     Statement has been filed and when the same has become effective, (ii) of
     the issuance by the SEC or any other federal or state governmental
     authority of any stop order suspending the effectiveness of the Purchaser
     Registration Statement or the initiation of any proceedings for that
     purpose, and (iii) of the occurrence of any event which makes any statement
     made in the Purchaser Registration Statement or related prospectus or
     prospectus supplement, or any document incorporated or deemed to be
     incorporated therein by reference, untrue in any material respect or which
     requires the making of any changes in the Purchaser Registration Statement,
     prospectus, any prospectus supplement or any such document so that, in the
     case of the Purchaser Registration Statement, it will not contain any
     untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary to make the statements therein
     not misleading and, in the case of the prospectus or prospectus supplement,
     it will not contain any untrue statement of a material fact or omit to
     state any material fact required to be stated or necessary to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading.

2.4  If requested by the holders holding a majority of the Consideration Shares
     being registered, (i) promptly incorporate in a prospectus supplement or
     post-effective amendment such information as such holders agree should be
     included therein and (ii) make all required filings of such prospectus
     supplement or such post-effective amendment as soon as practicable after
     the Purchaser has received notification of the matters to be incorporated
     in such prospectus supplement or post-effective amendment; provided,
     however, that the Purchaser will not be required to take any actions under
     this Section 2.4 that are not, in the opinion of independent counsel
     retained by the Purchaser, in compliance with applicable law.

                                     -48-


2.5  Deliver to each selling holder, without charge, as many copies of the
     prospectus or prospectuses relating to such Consideration Shares (including
     each preliminary prospectus) and any amendment or supplement thereto as
     such persons may reasonably request; and the Purchaser hereby consents to
     the use of such Prospectus or each amendment or supplement thereto by each
     of the selling holders in connection with the offering and sale of the
     Consideration Shares covered by such prospectus or any amendment or
     supplement thereto.

2.6  To register or qualify or cooperate with the selling holders in connection
     with the registration or qualification (or exemption from such registration
     or qualification) of such Consideration Shares for offer and sale under the
     securities or blue sky laws of such jurisdictions within the United States
     as any seller reasonably requests in writing; use all reasonable efforts to
     keep such registration or qualification (or exemption therefrom) effective
     during the period the Purchaser Registration Statement is required to be
     kept effective and do any and all other acts or things necessary or
     advisable to enable the disposition in each such jurisdiction of the
     Consideration Shares covered by the Purchaser Registration Statement;
     provided, however, that the Purchaser will not be required to (i) qualify
     to do business in any jurisdiction in which it is not then so qualified or
     (ii) take any action that would subject it to service of process in any
     such jurisdiction in which it is not then so subject.

2.7  Upon the occurrence of any event contemplated by Section 2.3(iii) hereof,
     prepare and file a supplement or post-effective amendment to the Purchaser
     Registration Statement or a supplement to the related prospectus or any
     document incorporated therein by reference or any other required document
     so that, as thereafter delivered to the purchasers of the Consideration
     Shares being sold thereunder, such prospectus will not contain an untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements therein, in light of
     the circumstances under which they were made, not misleading.

2.8  The Purchaser may require each seller of Consideration Shares as to which
     any registration is being effected to furnish to the Purchaser such
     information regarding the distribution of such Consideration Shares as the
     Purchaser may, from time to time, reasonably request in writing in order to
     provide adequate disclosure in the Purchaser Registration Statement and the
     Purchaser may exclude from such registration the Consideration Shares of
     any seller who unreasonably fails to furnish such information within a
     reasonable time after receiving such request.

3.   Registration Expenses.

     All fees and expenses incident to the performance of or compliance with the
     terms of this Schedule 2 by the Purchaser will be borne by the Purchaser.
     Such fees and expenses will include, without limitation, (i) all
     registration and filing fees (including, without limitation, fees and
     expenses for compliance with securities or "blue sky" laws), (ii) printing
     expenses (including, without limitation, expenses of printing certificates
     of Consideration Shares in a form eligible for deposit with The Depository
     Trust Company and of printing a reasonable number of prospectuses and
     prospectus supplements if the printing thereof is requested by the holders
     of a majority of the Consideration Shares participating in the offering),
     (iii) messenger, telephone and delivery expenses, (iv) fees and
     disbursements of counsel for the Purchaser, (v) fees and disbursements of
     all independent certified public accountants of Purchaser and (vi) fees and
     expenses of all other persons retained by the Purchaser. In addition, the
     Purchaser will pay its internal expenses (including, without limitation,
     all salaries and expenses of its officers and employees performing legal or
     accounting duties), the expenses of any annual audit, the fees and expenses
     incurred in connection with the listing of the securities to be registered
     on any securities exchange on which similar securities issued by the
     Purchaser are then listed and the fees and expenses of any person,
     including special experts, retained by the Purchaser. In no event, however,
     will the Purchaser be responsible for any selling commission with respect
     to any sale of Consideration Shares pursuant to this Agreement, and the
     holders shall be responsible on a pro rata basis for any taxes of any kind
     (including, without limitation, transfer taxes) with respect to any
     disposition, sale or transfer of Consideration Shares and for any legal,
     accounting and other expenses incurred by them in connection with any
     offering of Consideration Shares hereunder.

4.   Indemnification.

4.1  Indemnification by the Purchaser. The Purchaser will indemnify and hold
     harmless each holder of Consideration Shares registered pursuant to this
     Agreement, the officers, directors, agents and employees of each of them,
     each person who controls such a holder (within the meaning of Section 15 of
     the Securities Act or Section 20 of the Exchange Act) and the officers,
     directors, agents and employees of any such controlling person, from and
     against all losses, claims, damages, liabilities, costs (including, without
     limitation, reasonable attorneys' fees and expenses, and the costs incurred
     in connection with defending any investigation) and expenses (collectively,
     "Losses"), arising out of or based upon any untrue or alleged untrue
     statement of a material fact contained in the Purchaser Registration
     Statement, prospectus or form of prospectus or in any amendment or
     supplement thereto or in any preliminary prospectus, or arising out of or
     based upon any omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading, except insofar as the same are based solely upon
     information furnished in writing to the Purchaser by such holder expressly
     for use therein.

                                     -49-

 
4.2  Indemnification by Holders. In connection with the offering in which a
     holder is participating, such holder will furnish to the Purchaser in
     writing such information as the Purchaser may reasonably request for use in
     connection with the Purchaser Registration Statement, prospectus or any
     amendment or supplement thereto or preliminary prospectus and will
     indemnify, to the fullest extent permitted by law, the Purchaser, its
     respective directors and officers, agents and employees, each person who
     controls the Purchaser (within the meaning of Section 15 of the Securities
     Act and Section 20 of the Exchange Act), and the directors, officers,
     agents or employees of such controlling persons, from and against all
     Losses arising out of or based upon any untrue statement of a material fact
     contained in any Registration Statement, prospectus or any amendment or
     supplement thereto or preliminary prospectus or arising out of or based
     upon any omission of material fact required to be stated therein or
     necessary to make the statements therein not misleading, to the extent, but
     only to the extent, that such untrue statement or omission is contained in
     any information so furnished in writing by such holder to the Purchaser
     expressly for use in such Registration Statement, prospectus or any
     amendment or supplement thereto or preliminary prospectus.

4.3  Conduct of Indemnification Proceedings. If any person shall become entitled
     to indemnity hereunder (an "Indemnified Party"), such Indemnified Party
     shall give prompt notice to the party from which such indemnity is sought
     (the "Indemnifying Party") of any claim or of the commencement of any
     action or proceeding with respect to which such Indemnified Party seeks
     indemnification or contribution pursuant hereto; provided, however, that
     the failure to so notify the Indemnifying Party will not relieve the
     Indemnifying Party from any obligation or liability except to the extent
     that the Indemnifying Party has been prejudiced materially by such failure.
     In case any such action is brought against an Indemnified Party, unless in
     such Indemnified Party's reasonable judgment a conflict of interest between
     such Indemnified and Indemnifying Parties may exist in respect of such
     claim, the Indemnifying Party will be entitled to participate in and,
     jointly with any other Indemnifying Party similarly notified, to assume the
     defense thereof, to the extent that it may wish, with counsel reasonably
     satisfactory to such Indemnified Party, and after notice from the
     Indemnifying Party to such Indemnified Party of its election so to assume
     the defense thereof, the Indemnifying Party will not be liable to such
     Indemnified Party for any legal or other expenses subsequently incurred by
     the latter in connection with the defense thereof, unless in such
     Indemnified Party's reasonable judgment a conflict of interest between such
     Indemnified and Indemnifying Parties arises in respect of such claim after
     the assumption of the defense thereof, and the Indemnifying Party will not
     be subject to any liability for any settlement made without its consent
     (which consent shall not be unreasonably withheld). The Indemnifying Party
     will not consent to entry of any judgment or enter into any settlement or
     otherwise seek to terminate any action or proceeding in which any
     Indemnified Party is or could be a party and as to which indemnification or
     contribution could be sought by such Indemnified Party under this Section
     4, unless such judgment, settlement or other termination includes as an
     unconditional term thereof the giving by the claimant or plaintiff to such
     Indemnified Party of a release, in form and substance satisfactory to the
     Indemnified Party, from all liability in respect of such claim or
     litigation for which such Indemnified Party would be entitled to
     indemnification hereunder. An Indemnifying Party who is not entitled to, or
     elects not to, assume the defense of a claim will not be obligated to pay
     the fees and expenses of more than one counsel in any single jurisdiction
     for all parties indemnified by such Indemnifying Party with respect to such
     claim, unless in the reasonable judgment of any Indemnified Party a
     conflict of interest may exist between such Indemnified Party and any other
     of such Indemnified Parties with respect to such claim, in which event the
     Indemnifying Party shall be obligated to pay the fees and expenses of such
     additional counsel or counsels as may be reasonably necessary.
     Notwithstanding anything else to the contrary herein, and without limiting
     the rights set forth above, in any event any party will have the right to
     retain, at its own expense, counsel with respect to the defense of a claim.

4.4  Contribution. If the indemnification provided for in this Section 4 is
     unavailable to an Indemnified Party in respect of any Losses or is
     insufficient to hold such Indemnified Party harmless, then each applicable
     Indemnifying Party, in lieu of indemnifying such Indemnified Party, will,
     severally but not jointly, contribute to the amount paid or payable by such
     Indemnified Party as a result of such Losses, in such proportion as is
     appropriate to reflect the relative fault of the Indemnifying Party or
     Indemnifying Parties, on the one hand, and such Indemnified Party, on the
     other hand, in connection with the actions, statements or omissions that
     resulted in such Losses as well as any other relevant equitable
     considerations. The relative fault of such Indemnifying Party or
     Indemnifying Parties, on the one hand, and such Indemnified Party, on the
     other hand, will be determined by reference to, among other things, whether
     any action in question, including any untrue or alleged untrue statement of
     a material fact or omission or alleged omission of a material fact, has
     been taken or made by, or related to information supplied by, such
     Indemnifying Party or Indemnified Party, and the parties'

                                     -50-

 

     relative intent, knowledge, access to information and opportunity to
     correct or prevent such action, statement or omission. The amount paid or
     payable by a party as a result of any Losses will be deemed to include any
     legal or other fees or expenses incurred by such party in connection with
     any action or proceeding.

     The parties hereto agree that it would not be just and equitable if
     contribution pursuant to this Section 4.4 were determined by pro rata
     allocation or by any other method of allocation that does not take into
     account the equitable considerations referred to in the immediately
     preceding paragraph. No person guilty of fraudulent misrepresentation
     (within the meaning of Section 11(f) of the Securities Act) will be
     entitled to contribution from any person who was not guilty of such
     fraudulent misrepresentation.

     Notwithstanding the provisions of this Section 4, an Indemnifying Party
     that is a selling holder will not be required to pay any amount in respect
     of indemnity hereunder or contribute any amount hereunder in excess of the
     amount by which the total price at which the Consideration Shares sold by
     such Indemnifying Party were offered to the public exceeds the amount of
     any damages which such Indemnifying Party has otherwise been required to
     pay by reason of such untrue or alleged untrue statement or omission or
     alleged omission.

     The indemnity, contribution and expense reimbursement obligations of the

       7.7.2  The Final Salary Scheme is sufficiently and effectively funded on
              an on-going basis using the actuarial assumptions which were used

              currently, prospectively and contingently payable under the Final
              Salary Scheme at least to the extent to which they have accrued at
              the date of this Agreement.

              Scheme on retirement, death or leaving service and each Group
              Company may terminate any obligation it may have to contribute to

       7.7.5  No power or discretion to augment benefits under any of the 
              Schemes has been exercised in favour of an Employee in the last 5
              years as there is no obligation in respect of any employee to do
              so.

7.8  Disclosed Schemes - compliance

       7.8.1  The Schemes are Approved and none of the Vendors is aware of any
              circumstances which might give the Board of Inland Revenue reason
              to withdraw Approval.

       7.8.2  The Schemes are contracted-out schemes for the purposes of the
              Pension Schemes Act 1993 and have been administered in accordance
              with the contracting-out requirements of Part III of that Act.

       7.8.3  The Disclosed Schemes and the Executive Pension Plan have at all
              times been operated in accordance with their governing
              documentation and in accordance with all applicable laws and
              regulatory requirements including, without limitation, the
              requirements of Article 119 of the Treaty of Rome relating to
              equal benefits and admission to membership (except insofar as it
              relates to GMPs) and the requirements of the Pensions Act 1995.

7.9  Executive Pension Plan

The rules of and a current benefit statement for the Executive Pension Plan have
been disclosed to the Purchaser. The Executive Pension Plan is a defined
contribution scheme, of which John Charman is the only member. No person is
principal employer of the Executive Pension Plan other than CUAL, and no person
is a participating employer in the Executive Pension Plan other than CUAL. There
are no circumstances in which the liability (whether actual or contingent) of
CUAL (or any other Group Company) to the Executive Pension Plan could (in
aggregate) exceed 40 per cent. of the basic 

                                      -62-

 
annual salary of John Charman. Other than in the ordinary course of business,

8  Taxation Matters

8.1  Returns, Information and Clearances

       8.1.1  All returns, computations, notices and information which are or 
              have been required to be made or given by each Group Company for
              any Taxation purpose (i) have been made or given within the
              requisite periods and on a proper basis and are up-to-date and
              correct and (ii) none of them is, or is likely to be, the subject
              of any dispute with the Inland Revenue or other Taxation
              authorities.

       8.1.2  Each Group Company is in possession of sufficient information to
              enable it to compute its liability to Taxation insofar as it
              depends on any Transaction occurring on or before Completion.

8.2  Taxation Claims, Liabilities and Reliefs

       8.2.1  There are set out in the Vendors' Disclosure Letter, with express
              reference to this paragraph, details of all matters relating to
              Taxation in respect of which each Group Company (either alone or
              jointly with any other person) has, or at Completion will have, an
              outstanding entitlement to make: any claim (including a
              supplementary claim) for relief; any election, including an
              election for one type of relief, or one basis, system or method of
              Taxation, as opposed to another; any appeal or further appeal
              against an assessment to Taxation; any application for the
              postponement of, or payment by instalments of, Taxation; or to
              disclaim or require the postponement of any allowance or relief.
              Such details are reasonably sufficient to enable the Purchaser to
              procure that any time limit to such entitlement expiring within
              six months after Completion can be met.

       8.2.2  No relief (whether by way of deduction, reduction, set-off, 
              exemption, postponement, roll-over, hold-over, repayment or
              allowance or otherwise) from, against or in respect of any
              Taxation has been claimed and/or given to any Group Company which
              could or might be effectively withdrawn, postponed, restricted,
              clawed back or otherwise lost as a result of any act, omission,
              event or circumstance arising or occurring in the ordinary course
              of business at or at any time after Completion.

nowhere else at all times since its incorporation and will be so resident at
Completion.

8.5  Acquisitions from Members of the same Group

The entry into or Completion of this Agreement will not result in any profit or
gain being deemed to accrue to any Group Company for Taxation purposes, whether
pursuant to Section 179 of the Taxation of Chargeable Gains Act 1992 (TCGA) or
otherwise.

8.6  Replacement of Business Assets

No claim has been made under Section 152, 153, 154 or 175 TCGA or any other
section which would affect the amount of any gain accruing or being treated as
accruing on a disposal of an asset of any Group Company.

8.7  Base Values and Costs of Acquisition

If each of the assets (other than trading stock) or the plant and machinery
taken as a whole of each Group Company was disposed of for a consideration equal
to the book value of that asset or, as appropriate, plant and machinery in, or
adopted for the purpose of, the Audited Accounts, no liability to corporation
tax on chargeable gains or balancing charge under the Capital Allowances Act
1990 not fully provided for in the Audited Accounts would arise; and, for the
purpose of determining corporation tax on chargeable gains, there shall be
disregarded any relief and allowances available to the Group Company concerned
other than amounts falling to be deducted under Section 38 TCGA.

8.8  Rebasing

No Group Company has made a disposal to which Section 35 TCGA applies.

8.9  PAYE and National Insurance

duly accounting to the Inland Revenue for all sums so deducted and for all other
amounts for which it is required to account under the PAYE and National
Insurance contributions systems.

8.10  Depreciatory Transactions and Value Shifting

No asset owned by any Group Company has at any time since its acquisition by
that or any other Group Company or any company which has at any time been a
member of a group (as defined from time to time for any Taxation purpose) of
which the Group Company has at any time been a member 

                                      -64-

 
been subjected to a reduction in value such that any allowable loss arising on
its disposal is likely to be reduced or eliminated or any chargeable gain
arising on its disposal is likely to be increased.

8.11  Value Added Tax (VAT)

       8.11.1  Each Group Company has complied fully with all statutory 
               requirements, orders, provisions, directions or conditions
               relating to VAT, including (for the avoidance of doubt) the terms
               of any agreement reached with the Commissioners of Customs &
               Excise.

       8.11.2  No Group Company is a "developer" as defined in paragraph 5 
               Schedule 10 Value Added Tax Act 1994 in relation to any building
               or work within paragraph 5(2) of that Schedule or any

                    these policies voidable, nor have any circumstances arisen
                    which would render any of these policies void or

                    been any breach of the terms, conditions and warranties of
