                           1,764,856.90. None of the provisions of Clause 7 of
                           this Agreement shall apply to this indemnity nor
                           shall liability hereunder be qualified by the terms
                           of the Disclosure Letter.

         6.9      The provisions of Clause 4 of the Tax Undertaking shall apply
                  mutatis mutandis in respect of a Tax Claim (as defined
                  therein) to a liability under Clause 6.8.2 but the provisions
                  of Clause 2 of the Tax Undertaking shall not apply in respect
                  of such a liability nor shall the Warrantors be liable for
                  breach of any Warranty to the extent that the Purchaser or the
                  Company is entitled to make recovery under Clause 6.8 in
                  respect of the subject matter of the breach.

7        WARRANTY LIMITATIONS

         Save in the case of fraud

         7.1      The Warrantors shall be under no liability howsoever arising
                  in respect of any claim for any breach or non-fulfilment of
                  any of the Warranties or for any claim under the Tax
                  Undertaking (together in this Clause "a Claim") unless and to
                  the extent that the Purchaser, acting bona fide, has served on
                  each of the Warrantors a written notice thereof not later than
                  two years after Completion in the case of a Claim under the
                  Warranties and 7 years after Completion in the case of a Claim
                  under the Tax Undertaking giving details of the Claim
                  including the Purchaser's reasonable estimate of the amount of
                  any liability of the Warrantors in respect thereof based on
                  the information then available to the Purchaser. Any such
                  claim shall (if it has not been previously satisfied, settled
                  or withdrawn) be deemed to have been withdrawn 12 months after
                  service of such written notice (and the Warrantors shall have
                  no further liability in respect of it), unless proceedings in
                  respect of it have commenced by being warranted or signetted
                  by a relevant Scottish Court.

         7.2      The Warrantors shall have no liability under the Warranties in
                  respect of matters fairly and accurately disclosed in the
                  Disclosure Letter or the Supplemental Disclosure Letter.

         7.3      In relation to any Claim:-

                  7.3.1    the liability of each Warrantor in respect of all or
                           any Claims shall not exceed the Consideration paid to
                           such Warrantor in cash and/or Loan Notes.

                  7.3.2    the Warrantors shall have no liability unless the
                           aggregate amount of all claims under the Warranties
                           available to the Purchaser exceeds pound sterling
                           100,000 but in which event the Purchaser shall be
                           entitled to recover the whole amount of such claim.

                                       13



         7.4      If any Claim is based upon a liability of the Company or the
                  Purchaser which is contingent only, the Warrantors shall not
                  be liable hereunder to make any payment to the Purchaser or to
                  the Company unless and until such contingent liability becomes
                  an actual liability.

         7.5      The Purchaser will take all reasonable steps to avoid or
                  mitigate any loss or liability which might give rise to a
                  Claim.

         7.6      Where any claim is made by a third party against the Company
                  or the Purchaser and in relation to which it appears that the
                  Warrantors are or may be liable hereunder, the Purchaser shall
                  give notice thereof to the Warrantors and the Purchaser shall
                  (provided that the Warrantors shall indemnify and, if the
                  Purchaser acting reasonably so requires, secure the Purchaser
                  against liability for costs associated therewith) take such
                  action and procure that the Company shall take such action and
                  provide such assistance as the Warrantors (acting reasonably)
                  may require including instructing such professional advisers
                  as the Warrantors may nominate to avoid, dispute, resist,
                  appeal against, compromise or defend the claim and any
                  adjudication in respect thereof provided that the Warrantors
                  shall have the conduct of any proceedings in respect of any
                  such claim or any such adjudication.

         7.7      7.7.1    Where the Purchaser is or becomes entitled (whether
                           under any insurance or by way of payment, discount,
                           credit, set off, counterclaim or otherwise) to
                           recover from any third party (including any Taxation
                           Authority) any sum in respect of Taxation or any
                           other loss, damage or liability which is or may be
                           the subject of a Claim, the Purchaser shall, if so
                           required by the Warrantors and subject to Clause
                           7.7.2 take all such steps or proceedings as the
                           Warrantors may reasonably require to enforce such
                           recovery.

                  7.7.2    All such steps or proceedings shall be taken at the
                           Warrantors' cost and expense and the Purchaser shall
                           not be under any obligation to take them or procure
                           them to be taken unless the Warrantors shall have
                           provided indemnities and security to the reasonable
                           satisfaction of the Purchaser in respect of all costs
                           and expenses likely to be thereby incurred.

                  7.7.3    The Purchaser shall procure that the Warrantors are
                           provided (at the expense of the Warrantors) with all
                           such information and reports concerning any such
                           steps or proceedings taken by the Purchaser as the
                           Warrantors may from time to time reasonably request.

                  7.7.4    If any such sum as is referred to in Clause 7.7.1
                           shall be recovered by the Purchaser from the third
                           party, any Claim by the Purchaser in respect of any
                           Taxation or other loss, damage or liability to which
                           the sum relates shall be limited (without prejudice
                           to any other limitations on the liability of

                                       14



                           the Warrantors referred to in this Clause 7) to the
                           amount (if any) by which the amount of such Taxation
                           or other loss, damage or liability is exceeds the
                           aggregate of:-

                 7.7.4.1   the sum recovered less all costs, charges and
                           expenses properly incurred by the Purchaser in
                           recovering that sum from the third party; and

                 7.7.4.2   any sum or sums previously paid by the
                           Warrantors to the Purchaser in respect of such
                           Taxation or other loss, damage or liability.

                  7.7.5    If the aggregate of the sums referred to in Clause
                           7.7.4.1 and 7.7.4.2 exceeds the amount of Taxation or
                           other loss, damage or liability to which the sum
                           recovered relates, the Purchaser shall as soon as
                           reasonably practicable pay to the Warrantors the
                           amount of the excess.

         7.8      The Warrantors shall have no liability for any Claims to the
                  extent that they are a result of or are otherwise attributable
                  to:

                  7.8.1    any matter expressly provided for in this Agreement
                           or in its implementation;

                  7.8.2    any voluntary act, matter or thing done or omitted to
                           be done by the Purchaser or the Company or at the
                           request or with the approval of the Purchaser after
                           Completion;

                  7.8.3    any legislation not in force at the date hereof or
                           any change of law or administrative practice which
                           takes effect retroactively or any increase in the
                           rates of taxation or withdrawal of any concession in
                           force at the date hereof;

                  7.8.4    any change in accounting policy or practice of the
                           Purchaser or the Company introduced or having effect
                           after Completion other than any such change made so
                           as to comply with any Standard Statement of
                           Accounting Practice in the UK.

         7.9      The Warrantors shall have no liability for any Claims:-

                  7.9.1    if and to the extent that the Company would have been
                           indemnified in respect of the loss giving rise to the
                           Claim had it maintained after Completion insurance
                           cover at a level and type equal to that existing
                           immediately prior to the date of this Agreement; or

                  7.9.2    where provision or reserve in respect of the
                           circumstance giving rise to the Claim has been made
                           in the Accounts or the Management Accounts and in


<PAGE>   16

                                       15



                           the case of the Management Accounts provided that the
                           relevant provision or reserve is specifically
                           identified in the relevant supporting papers.

         7.10     If a Claim shall arise hereunder and under the Tax Undertaking
                  with reference to the same circumstances of claim the
                  Purchaser shall (if appropriate) be entitled to recover such
                  Claim under either the Warranties or the Tax Undertaking but
                  not both.

         7.11     Any amount paid by the Warrantors in respect of any Claim
                  shall be deemed to constitute a reduction in the Consideration
                  received by them pursuant to this Agreement.

         7.12     The Purchaser will not be entitled to recover damages in
                  respect of any Claim or obtain reimbursement or restitution
                  more than once in respect of the same misrepresentation or
                  breach of any particular Warranty.

         7.13     As soon as is reasonably practicable, upon receipt of a
                  written request, the Purchaser will give or ensure that there
                  is given to the Warrantors and their professional advisers
                  full access during business hours at a mutually convenient
                  time to all relevant accounts, documents and records within
                  the possession or control of the Purchaser or the Company or
                  the Subsidiaries to enable the Warrantors and such advisers to
                  consider any Claim made by the Purchaser or as may reasonably
                  be required in connection with any returns by the Company to
                  any fiscal, governmental or other regulatory body and for such
                  purpose the Warrantors and such professional advisers will be
                  permitted (at the expense of the Warrantors) to take copies of
                  all such relevant accounts, documents and records.

         7.14     The Warrantors will appoint one firm of solicitors (and if
                  relevant one firm of Chartered Accountants only) to act on
                  their behalf and shall nominate one of their number to be
                  their agent for the purpose of dealing with the Purchaser, its
                  solicitors or accountants under this Clause 7.

         7.15     The Purchaser will use reasonable endeavours to procure that
                  the Company retains and preserves all books, records,
                  documents and information (including information recorded or
                  retained in any electronic form) of, or relating to the
                  Company which are or may be relevant in connection with any
                  Claim or Claims brought by the Purchaser against the
                  Warrantors for so long as any actual or prospective Claims
                  remain outstanding.

         7.16     In this Clause 7, where reference is made to "the Company" in
                  respect of acts, omissions, requests, approvals or consents
                  (herein "Actions") such shall only exclude or limit liability
                  on the part of the Warrantors provided such Actions have been
                  disclosed by the Warrantors (to the extent that they are at
                  the relevant time continuing employees of the Company) to the
                  board of directors of the Company and approved by it having
                  regard to the best interests of the Company.

         7.17     The Purchaser shall be entitled to set off, in priority to but
                  without prejudice to any other rights and remedies which
                  remain after exercise of the right of set-off contained
                  herein, the amount of any liability of the Warrantors to the
                  Purchaser under Clause 6 and the Schedule Part 3 of this
                  Agreement or of the Covenantors to the Purchaser under (and as
                  defined in) the Tax Undertaking against any amount (whether by
                  way of principal or interest) payable by the Purchaser to the
                  Warrantor(s) in respect of the Loan Notes, to the extent that
                  the liability in question constitutes a relevant Claim in
                  terms of this Agreement or under the Tax Undertaking and
                  either (i) is the subject of a judgement of a court of
                  competent jurisdiction in favour of the Purchaser in respect
                  of which the period of any appeal which may be competent has
                  passed or (ii) has been agreed to in writing by the Warrantors
                  (or in their capacity as Covenantors, as the case may be) to
                  be then due and payable to the Purchaser, and such liability
                  shall not have been paid to the Purchaser for a period of 14
                  days from when it first became due and payable.

8        BREACH ETC. ON OR BEFORE COMPLETION

         8.1      If at any time on or before the Completion Date:-

                  8.1.1    the Purchaser becomes aware of any fact or event (not
                           being a fact or event provided for or contemplated by
                           this Agreement) which in its reasonable opinion is a
                           material breach of any of the Warranties or is likely
                           to give rise to a material claim under the Tax
                           Undertaking (if executed), or

                  8.1.2    the Company sustains loss or damage on account of
                           fire, flood, explosion, death strike or any other
                           similar cause which in the reasonable opinion of the
                           Purchaser materially and adversely affects the value
                           of the Shares or the manner in which the Company can
                           continue to carry on its business

                  then the Purchaser may, by written notice to the Vendors elect
                  to rescind this Agreement (in which event no party will have
                  any claim against any other party in relation to this
                  Agreement and the matters contemplated herein) or to proceed
                  to Completion, in which event the terms of this Agreement
                  shall continue to apply and so that subject to the foregoing
                  if the Purchaser elects to so complete it waives any Claim in
                  relation to the relevant matter which has arisen under Clause
                  8.1 of this Agreement.

         8.2      For the purposes of Clause 8.1 a matter shall be material if
                  it would give rise to a claim which, taking account of all
                  relevant circumstances is or would be likely to be greater
                  than pound sterling 250,000.

         8.3      The Warrantors undertake to the Purchaser that (save as
                  otherwise agreed in writing by the Purchaser and the

                  any company which is under the control of that Vendor under
                  section 767A or 767AA ICTA (and any reasonable costs and
                  expenses incurred by the Vendor or that company in relation to
                  such Taxation liability or in making any claim under this
                  clause 24.1) at the time such Taxation liability is imposed,
                  where such Taxation liability arises as a result of the
                  failure by the Company to discharge after Completion a
                  Taxation liability for which the Company is primarily liable
                  and which is not within clause 2.1 of the Tax Undertaking.

         24.2     If the Purchaser becomes liable to make a payment under clause
                  24.1, the Purchaser shall (subject to Clause 24.4) pay such
                  amount in cleared immediately available funds on or before the
                  later of the date 2 business days before that Taxation
                  liability is finally due and payable and the date 5 business
                  days after the date of written demand on the Purchaser by the
                  relevant Vendor.

         24.3     The Purchaser shall not be required to make any payment
                  pursuant to clause 24.1 unless that Vendor and each company in
                  respect of that Vendor referred to in clause

                  24.1 shall enter into a binding irrevocable undertaking not to
                  seek to recover any amount from the Company in respect of the
                  Taxation liability in question pursuant to section 767B ICTA
                  1988.

         24.4     The provision of Clause 7.17 (set off) will apply (mutatis
                  mutandis) in relation to any amount which would otherwise be
                  payable to the Warrantors under clause 24.2.

                                     PART 3

                                 THE WARRANTIES

In this part of the Schedule, where reference is made in a warranted statement
to "the Company" that shall be deemed to include a reference to each and all of
the Subsidiaries (where the context so permits).

                  THE COMPANY AND ITS SHARE CAPITAL AND RECORDS

         1.1      The facts and information relating to the Company set out in
                  the Agreement, (including the Schedule Part 1 and Part 2 and
                  the recitals thereto) and the written information comprised in
                  the Appendix to this Agreement and initialled on the index
                  page by the Purchaser's Solicitors and the Vendors' Solicitors
                  was when given and remains true and accurate in all respects
                  and not misleading.

         1.2      The Group's budgeted activity levels and profit forecast (a
                  copy of which are attached hereto) are based on facts which
                  are true and accurate in material respects, and the opinions
                  and forecasts contained therein are made on reasonable
                  grounds. There is no fact or circumstance known to the
                  Warrantors which would invalidate to any material extent such
                  opinions or forecasts.

2        The Company

         2.1      is neither the holder nor beneficial owner of any class of the
                  shares or other capital of any other Company (whether
                  incorporated in the United Kingdom or elsewhere) other than
                  the Subsidiaries; and

         2.2      is not a member of any partnership or other unincorporated
                  association (other than recognised trade associations).

3        No one is entitled to receive from the Company a finder's fee,
         brokerage or other commission in connection with the sale and purchase
         of the Shares pursuant to this Agreement.

4        None of the Shares has been the subject of a transfer which is
         challengeable under Sections 242 or 243 of the Insolvency Act 1986
         within the period of five years prior to the date of execution of this
         Agreement.

5        All dividends or distributions of profits made or paid by the Company
         have been declared, made or paid in accordance with the Act and the
         Company's Articles of Association, and all dividends declared or
         otherwise due in respect of the Shares have been paid.

6        The Shares comprise the whole of the Company's allotted and issued
         share capital and are fully paid or properly credited as fully paid.
         There are no agreements in force which call for


<PAGE>   38

                                       37



         the present or future issue or transfer of or grant to any person, firm
         or company the right whether conditional or otherwise to call for the
         issue or transfer of any share or loan capital of the Company
         (including the Shares) nor for the grant of any option, nor is there
         any right of pre-emption over the Shares. There is no mortgage, charge,
         pledge, lien or other security over the Shares or agreement to create
         such a security.

7        The Company has not issued any loan stock, loan notes, loan capital or
         debentures which are outstanding.

8        The Company has not at any time since 1 December 1993:-

         8.1      repaid or agreed to repay or redeem any of the Shares or any
                  class of its share capital or otherwise reduced or agreed to
                  reduce its share capital or any class thereof otherwise than
                  in accordance with the Company's Articles of Association;

         8.2      capitalised or agreed to capitalise in the form of shares or
                  debentures or other securities, or in paying up any amounts
                  unpaid on any shares, debentures or other securities, any
                  profits or reserves of any class or description, or passed or
                  agreed to pass any resolution to do so; or

                  assistance in connection with the purchase of any of its own
                  shares.

9        The copy of the Memorandum and Articles of Association of the Company
         annexed to the Disclosure Letter are true and accurate in all respects
         and up-to-date. The Company's Statutory Books and Records, including
         its Register of Members have been properly kept and contain an accurate
         and complete record of the matters which should be dealt with therein.
         No notice or allegation that any of the same is incorrect or should be
         rectified has been received by the Company. All returns, particulars,
         resolutions and other documents required to be prepared, filed with or
         delivered to the Registrar of Companies or any other statutory,
         governmental or regulatory authority by the Company have been correctly
         and properly prepared and filed and delivered.

10       Each of the Warrantors has the full legal right and capacity and full
         power and authority, and has taken all action required, to sign this
         Agreement, all the documents to be signed by him at Completion and to
         perform his obligations under same, and this Agreement constitutes, and
         (as applicable) the Tax Undertaking and all other documents to be
         signed by him at Completion, when executed, will constitute,
         obligations binding on each of the Warrantors in accordance with their
         terms.

11       None of the accounts, books and records of the Company's business,
         assets and/or activities is maintained, recorded or in any other manner
         dependent in whole or in part upon any electronic, mechanical or
         photographic or other process (whether computerised or not) which


<PAGE>   39

                                       38



         is not under the exclusive ownership and direct control of the Company.

            THE COMPANY'S BUSINESS, CONTRACTS AND OWNERSHIP OF ASSETS

12       No contract has been entered into or commitment incurred by the Company
         or in which it has an interest which

         12.1     is outside its ordinary and proper course of business or

         12.2     imposes an obligation of unusual length or which is unduly
                  onerous or is likely to result in a loss to the Company on its
                  completion or

         12.3     is on other than an arm's length basis or is one in which any
                  Vendor is interested directly or indirectly;

         12.4     involves a liability to pay liquidate or pre-estimated damages
                  (or a penalty) on breach thereof;

         12.5     involves or is likely to involve an obligation (whether for
                  the supply of goods or services or otherwise) the aggregate
                  value of which in any period of twelve months will or is
                  likely to be more than 10% of the amount of the Company's
                  turnover as measured by reference to the financial year ended
                  on the Accounts Date.

13       Neither the profits of the Company nor the financial position of the
         Company has been affected by any contract or arrangement of the Company
         which is or was not on an entirely arms length basis.

14       The Company is not in material breach of contract with any third party
         and no event has occurred which constitutes, or which with the giving
         of notice and/or the lapse of time would constitute, a breach of, or
         default under, any agreement or arrangement to which the Company is a
         party. No event has occurred which would entitle any party to avoid,
         repudiate or otherwise terminate any contract or any benefit enjoyed by
         the Company.

15       The Company is not a party to any subsisting agency or distributorship
         agreement nor has it any outstanding liability to any former agent or
         distributor.

16       The Company is not a party to any written agreement or written
         arrangement under the terms of which any other party shall by reason of
         any change in the beneficial ownership of shares in the Company's
         capital be entitled to terminate the agreement or arrangement earlier
         than it would otherwise have been liable to be terminated or require
         the adoption of terms less favourable to the Company than those
         subsisting in the absence of the change.

17       The Company is not a party to any agreement or arrangement which
         imposes any restriction on its freedom to borrow or give security or
         dispose of its assets or which involve exclusive


<PAGE>   40

                                       39



         purchasing obligations or restrictive covenants in relation to sales.

18       The Company is not under any obligation or a party to any contract
         which cannot readily be fulfilled or performed by it on time and
         without undue or unusual expenditure of money or effort.

19       No person has been appointed agent of the Company for any purpose
         whatsoever and the Company has not given any power of attorney or any
         other authority (express implied or ostensible) which is still
         outstanding or effective to any person to enter into any contract or
         commitment or do anything on its behalf (other than any authority of
         officers and employees to enter into routine trading contracts in the
         normal course of their duties).

20       Other than in the ordinary course of business, no offer or tender has
         been given or made by the Company which is still outstanding and which
         is capable of giving rise to a contract merely by any unilateral act of
         a third party.

21       The Company has not in the twelve months prior to Completion used any
         standard terms and conditions of business other than those disclosed in
         the Disclosure Letter.

22       None of the Company's assets have been acquired for a consideration in
         excess of, or disposed of for less than, the market value at the date
         of such acquisition or disposal.

23       23.1     Other than in relation to the Properties which are subject to
                  the terms of separate Warranties as to title herein, the
                  Company has a good title to its whole assets, free of any
                  mortgage or other security, express or implied (excluding
                  retention of title imposed under standard supplier terms and
                  conditions).

         23.2     All of the Company's assets are in working order and in
                  reasonable condition having regard to their age and have been
                  properly maintained and where applicable serviced in
                  accordance with (as applicable) manufacturer's
                  recommendations, the requirements of any supply, leasing or
                  financing agreement and good industry practice and conform to
                  all relevant statutory requirements. No material repairs or
                  other work (excluding routine maintenance) requires to be
                  carried out in respect of such assets.

24       24.1     The Company's stock and work-in-progress is in good condition
                  and can be sold by the Company in the ordinary course of
                  business.

         24.2     The Company's stock of raw materials, packaging and finished
                  goods held is not excessive and is adequate in relation to the
                  current trading requirements of the Company.

25       The Company owned at the Accounts Date all the assets represented in
         the Accounts as being owned by the Company and (save for disposals for
         value in the ordinary course of its trade) still owns such assets and
         no person has any option or right to acquire such assets.

                                       40


26       The Company is not subject to any liability or obligation (save as may
         be implied by law) whether by way of guarantee, warranty or otherwise
         to service, repair, maintain, replace or take back any goods supplied
         by it on terms other than under any standard form contracts disclosed
         in the Disclosure Letter.

27       Full details of any hire or hire purchase agreement or credit sale
         agreement or agreement for payment on deferred terms to which the
         Company is a party are referred to in the Disclosure Letter and the
         Company has observed and performed in all respects all the terms and
         conditions on its part to be observed and performed in all such
         agreements.

28       Other than those referred to in the Schedule hereto, there are no
         loans, guarantees or undertakings, mortgages, charges indemnities or
         other liabilities (including contingent liabilities) which have been
         given or made or incurred by or assigned to or vested in and are
         outstanding in respect of the Company.

29       29.1     All the  stock-in-trade,  the  Properties  and the  assets
                  and undertaking of the Company of an insurable nature, have at
                  all relevant times since 1 December 1993 or (in relation to
                  the assets located at the Maldon Property) since 21 August
                  1995 been adequately insured against fire, accident, damage,
                  injury, third party loss, loss of profits and other risks
                  normally insured against by persons carrying on the same class
                  of business as that carried on by the Company, and all such
                  insurance is currently in full force and effect and nothing
                  has been done or is to be done which would make any policy of
                  insurance void or voidable. No claims are currently
                  outstanding or pending or threatened nor have circumstances
                  arisen which would entitle a claim to be made under any such
                  policy.

         29.2     So far as the Warrantors are aware, within the period of
                  commencement of the Company's trading to 30 November 1993, and
                  since that date, no application or proposal for a policy of
                  insurance of any kind whatsoever made by the Company has been
                  refused or rejected by any insurance company in whole or in
                  part nor within the said period has the level of insurance
                  cover provided by any policy of insurance of any kind
                  whatsoever existing at any time during the said period in
                  favour of the Company been reduced or in any way altered at
                  the instance of the insurance company issuing such policy of
                  insurance.

         29.3     Copies of all or summaries of all policies of insurance
                  effected by the Company since 1 December 1993 (and by the
                  Landlords in relation to the Leased Properties and the
                  building contractors in relation to the construction of the
                  New Kelso Property) are attached to the Disclosure Letter.
                  None of the insurance policies maintained by the Company is
                  subject to special or unusual terms or restrictions or to the
                  payment of a premium in excess of the normal rate.

         29.4     All insurances have at all relevant times since 1 December
                  1993 been effected by the



<PAGE>   42

                  Company on the basis that cover is given in respect of claims
                  arising in relation to acts or omissions occurring during the
                  period covered by the insurance notwithstanding the date of
                  the claim.

                  the century to eliminate date ambiguity without human
                  intervention including leap year calculations; and

         65.4     the year 2000 is being recognised as a leap year.

         Kelso Property) are so far as the Warrantors are aware in good repair
         and condition (having regard to their age) and are substantially fit
         for the purpose for which they are at present used and there are no
         major repairs contracted for or demanded by the Landlord or proposed in

                  alterations or additions to, any building or other erection on
                  the Properties.

         89.2     no part of the Properties have since 1 December 1993 (in

         which were true and accurate in all material respects when made and as

         relevant excise authorities in respect of taxation for all periods down
         to the Accounts Date and have continued to be submitted on or before
         the due date where the due date falls before Completion in respect of
         later periods; there is no dispute with any such tax authority and the
         Warrantors have no reason to suppose that any of such computations and
         returns be the subject of such a dispute.

91       Claims have been timeously submitted for all reliefs from tax assumed
         to be claimed for the purposes of the Accounts. The Warrantors are not
         aware of any reason whereby the Company would be disentitled to claim
         any such relief.

         cause a discovery to be made or investigation to commence.

93       The Company has duly paid all tax for which it has been liable and
         which has fallen due for payment by it as and when due and the Company
         has not at any time been required to pay nor as far as the Warrantors
         are aware have circumstances arisen which may give rise to a liability
         to any penalty, fine, surcharge or interest under the provisions of the
         Taxes Management Act 1970, the Value Added Tax Acts 1983 and 1994, the
         Finance Act 1985, the Customs & Excise Management Act 1979, the Stamp
         Act 1891 and the Stamp Duties Management Act 1891 or otherwise. So far
         as the Warrantors are aware no circumstance has arisen whereby the
         Company will be liable to make payment of any tax which might be the
         subject of a claim by the Purchaser under the Tax Undertaking .

94       The Company has duly deducted and accounted to the Inland Revenue for
         all tax required to be deducted from any payment made by it including

                  terms of S349 and 350 of the Taxes Act, and

         94.2     from payments to sub-contractors in the construction industry
                  (S559-567 of the Taxes Act).

95       No relief or deferment from Corporation Tax in respect of chargeable
         gains has been obtained by the Company in respect of the replacement of
         business assets pursuant to Sections 165, 247, 152, 153 or 175 of TCGA
         which will affect the chargeable gain or allowable loss which would
         arise on a disposal by the Company of any of its assets.

96       The Company has not at any time since 6 April, 1965 repaid or redeemed
         or agreed to repay or redeem any shares of any class of its issued
         share capital, nor capitalised or agreed to capitalise in the form of
         shares or debentures any profits or reserves of any class or

         the purposes of the Capital Allowances Act 1990 of any pool of assets

         pool shown or adopted for the purposes of the Accounts and the written
         down value of any other asset for the purposes of the Capital
         Allowances Act 1990 is not less than the book value of that asset shown
         or adopted for the purposes of the Accounts.

         course of business by reason of which any balancing charge may be made
         against or any disposal value may be brought into account by the

         valid election has been made under Section 158 of the Capital
         Allowances Act 1990. (sales between connected persons).

104      The Company is not in dispute with any person as to its entitlement to
         capital allowances under Section 57(7) of the Capital Allowances Act
         1990 and there are no circumstances which could give rise to such
         dispute. (ownership of fixtures severed from land).

105      No securities within the meaning of Section 254 (1) of the Taxes Act
         issued by the Company and remaining in issue at the date hereof were
         issued in such circumstances that the interest payable thereon falls to

         Scheme.

         of Chapter IV of Part XIV of the Taxes Act and so far as the Warrantors

4        DISPUTES AND CONDUCT OF TAX CLAIMS

         4.1      If the Purchaser or the Company (as the case may be) shall
                  become aware of a Tax Claim, the Purchaser shall or shall
                  procure that the Company shall within a reasonable time
                  thereafter give written notice thereof to the Covenantors and
                  in any event within 14 days of receipt.

         4.2      If the Covenantors shall secure the Company and/or (as the

                  Purchaser to the Purchaser's reasonable satisfaction against
                  all liabilities, costs, damages or expenses which may be
                  properly incurred thereby including any additional Liability
                  for Taxation, the Purchaser shall and shall procure that the
                  Company shall take such action as the Covenantors may
                  reasonably request by notice in writing given to the Company
                  and the Purchaser to avoid, mitigate, dispute, defend, resist,
                  appeal or compromise any Tax Claim (such a Tax Claim where
                  action is so requested being hereinafter referred to as a
                  "Dispute"). Provided that neither the Company nor the
                  Purchaser shall be obliged to appeal or procure an appeal
                  against any assessment to Taxation raised on either of them
                  if, the Covenantors having been given written notice of the
                  receipt of such assessment, the Company and the Purchaser have
                  not within 21 days of the date of the notice received
                  instructions in writing from the Covenantors to do so.

         4.3      If (1) the Covenantors do not request the Purchaser or the
                  Company to take any action under sub-clause 4.2 of this Deed
                  or fail to secure the Purchaser and the Company to the
                  Purchaser's reasonable satisfaction within a period of time
                  (commencing with the date of the notice given to the
                  Covenantors that is reasonable having regard to the nature of
                  the Tax Claim and the existence of any time limit in relation
                  to avoiding, disputing, defending, resting, appealing or
                  compromising such Tax Claim) and which period shall not in any
                  event exceed a period of 42 days or (2) the Tax Claim alleges
                  on reasonable grounds that fraud or a criminal offence has
                  been committed by the Covenantors or, on or before Completion,
                  by the Company, the Purchaser or Company shall have the
                  conduct of the Dispute absolutely (without prejudice to its
                  rights under this Deed) and shall be free to pay or settle the
                  Tax Claim on such terms as the Purchaser or the Company may in
                  its absolute discretion consider fit without prejudice to any
                  rights of the Covenantors against either of them.

         4.4      Subject to sub-clause 4.3, at the written request of the
                  Covenantors the conduct of a Dispute shall be delegated to the
                  Covenantors Provided that, unless the Purchaser and the
                  Company and the Covenantors specifically agree otherwise in
                  writing, the following terms shall apply;

                  4.4.1    the Company and the Purchaser shall promptly be kept
                           informed of all matters pertaining to the Dispute and
                           shall be entitled to see and keep copies of all
                           correspondence and notes or other written records of
                           meetings with representatives of the Tax Authority in
                           question to the extent that it relates to the
                           Dispute;

                  4.4.2    the appointment of solicitors or other professional
                           advisers to act in the name of the Company shall be
                           subject to the approval of the Purchaser, such
                           approval not to be unreasonably withheld or delayed;

                  4.4.3    all material written communications pertaining to the
                           Dispute which are to

                           be transmitted to the relevant Taxation Authority
                           shall first be submitted to the Purchaser and the
                           Company for approval and shall only be finally
                           transmitted if such approval is given, which approval
                           is not to be unreasonably withheld or delayed; and

                  4.4.4    the Covenantors shall make no settlement or
                           compromise of the Dispute or agree any matter in the
                           conduct of the Dispute without the prior approval of
                           the Company, such approval the Purchaser shall
                           procure shall not be unreasonably withheld or
                           delayed.

         4.5      Neither the Purchaser nor the Company shall be subject to any
                  claim by or liability to either of the Covenantors for
                  non-compliance with any of the foregoing provisions of this
                  Clause 4 if the Purchaser or the Company has bona fide acted
                  in accordance with the instructions of [any one or more of the
                  Covenantors].

5        PAYMENT DATE AND INTEREST

         5.1      Where the Covenantors are liable to make any payment under
                  Clause 2, the due date for the making of that payment (the
                  "Due Date") shall be the later of the date falling seven days
                  after the Purchaser has served a notice on the Covenantors
                  demanding that payment and;

                  5.1.1    in a case that involves an actual payment of Taxation
                           by the Company, the date on which the Taxation in
                           question would have had to have been paid to the
                           relevant Taxation Authority in order to prevent a
                           liability to interest or a fine, surcharge or penalty
                           from arising in respect of the Liability for Taxation
                           in question; or

                  5.1.2    in any case that involves a Liability for Taxation
                           falling within Clause 1.4.1 the last date upon which
                           the Taxation referred to in that clause is or would
                           have been required to be paid by the Company to the
                           relevant Taxation Authority; or

                  5.1.3    in any case that involves a Liability for Taxation
                           falling within Clause 1.4.2 the date upon which the
                           repayment was due from the relevant Taxation
                           Authority; or

                  5.1.4    in any case that involves a Liability for Taxation
                           falling within Clause 1.4.3 the date upon which the
                           Taxation for which the Company becomes liable is
                           required to be paid to the relevant Taxation
                           Authority.

         5.2      If any sums required to be paid by the Covenantors under this
                  Deed are not paid on the Due Date, then, except to the extent
                  that the Covenantors' liability under Clause 2 compensates the
                  Purchaser for the late payment by virtue of it extending to



<PAGE>   74
                                       73




                  interest and penalties, such sums shall bear interest (which
                  shall accrue from day to day after as well as before any
                  judgement from the same) at the rate of 2 per cent per annum
                  over the base rate from time to time of Bank of Scotland from
                  the date following the Due Date up to and including the day of
                  actual payment of such sums.

6        TAXATION OF PAYMENTS

         6.1      Any sum payable by the Covenantors to the Purchaser under this
                  Deed shall be paid free and clear of any deduction or
                  withholding whatsoever, save only as may be required by law.

         6.2      If any deduction or withholding is required by law to be made
                  from any payment by the Covenantors under this Deed (other
                  than a payment made pursuant to Clause 5.3) or if (ignoring
                  any Accounts Relief or Post-Completion Relief) the Purchaser
                  is subject to Taxation in respect of such payment the
                  Covenantors shall (save to the extent the Purchaser is
                  entitled to credit for such deduction or withholding) increase
                  the amount of the payment by such additional amount as is
                  necessary to ensure that the net amount received and retained
                  by the Purchaser (after taking account of all deductions or
                  withholdings or Taxation) is equal to the amount which it
                  would have received and retained had the payment in question
                  not been subject to any deductions or withholdings or
                  Taxation.

         6.3      The provision of Clause 6.2 shall not require the Covenantors
                  to make any such additional payment as is referred to therein
                  to the extent that the payment by the Covenantors is subject
                  to Taxation as a result of any act or omission of the
                  Purchaser or the Company on or after Completion.

7        RECOVERY FROM OTHER PERSONS

                  becomes aware that it may be entitled to recover from some
                  other person not being the Purchaser, the Company or any other
                  company within the same group companies as the Purchaser or
                  the Company any amount which is referable to a Liability for
                  Taxation which has resulted in a liability of the Covenantors
                  to make payment under this Deed or to make a Saving, the
                  Purchaser shall or shall procure that the Company shall:

                  7.1.1    notify the Covenantors of its entitlement or
                           potential entitlement; and

                  7.1.2    if required by the Covenantors and, subject to the
                           Purchaser and the Company being indemnified by the
                           Covenantors against any Taxation that may be suffered
                           on receipt of that amount and secured against any
                           costs and expenses incurred in recovering that
                           amount, take or procure that the Company takes all
                           reasonable steps to enforce that recovery or to make
                           that Saving.

                                       74




         7.2      If the Purchaser or the Company recovers any amount referred
                  to in sub-clause 7.1 or obtains such a Saving the Purchaser
                  shall account to the Covenantors for the lesser of:

                  7.2.1    any amount recovered (including any related interest
                           or related repayment supplement) less any Taxation
                           suffered in respect of that amount and any costs and
                           expenses incurred in recovering that amount (save to
                           the extent that that amount has already been made
                           good by the Covenantors under sub-clause 7.1.2) or

8        CORPORATION TAX RETURNS

         8.1      The Covenantors or their duly authorised agents shall (at the
                  Company's cost and expense) prepare the corporation tax
                  returns and computations of the Company for all accounting
                  periods ended on or prior to the Accounts Date, to the extent
                  that the same shall not have been prepared before Completion,
                  and submit them to the Purchaser.

         8.2      The Purchaser shall procure that the returns and computations
                  mentioned in sub-clause 8.1 shall be authorised, signed and
                  submitted to HM Inspector of Taxes without amendment or only
                  with such amendments as the Purchaser reasonably considers to
                  be necessary so as to make them true and accurate in all
                  respects and as to which the Covenantors shall agree (such
                  agreement not to be unreasonably withheld or delayed) and
                  shall give the Covenantors or their agents all such assistance
                  as may reasonably be required (at the Company's cost and
                  expense) to agree those returns and computations with HM
                  Inspector of Taxes.

         8.3      The Covenantors or their duly authorised agents shall (at the
                  Company's cost and expense) prepare all documentation and
                  shall have conduct of all matters (including correspondence)
                  relating to the corporation tax returns and computations of
                  the Company for all accounting periods ended on or prior to
                  the Accounts Date provided that the Covenantors shall not
                  without the prior written consent of the Purchaser (not to be
                  unreasonably withheld or delayed) transmit any substantive
                  communication to HM Inspector of Taxes.

         8.4      The Purchaser shall procure that the Company affords such
                  access to its books, accounts and records as is necessary and
                  reasonable to enable the Covenantors or their duly authorised
                  agents to prepare the corporation tax returns and computations
                  of the Company for all accounting periods ended on or before
                  the Accounts Date and conduct matters relating to them in
