         necessary to procure the satisfaction of the Condition including, but
         not limited to, the provision by all parties of all information
         reasonably necessary and providing such assistance as may reasonably be
         required.

         shall sell, and the Purchaser shall buy, the Sale Shares with full
         title guarantee free from all Encumbrances and together with all rights
         that attach (or may in the future attach) to them including, in
         particular, the right to receive all dividends and distributions

         of clause 4.6) (pound)3,100,000 payable in cash at Completion to the
         Vendor's Solicitors.

4.2      The Purchase Price shall be deemed to be reduced by the amount of any
         payment made to the Purchaser:

         (a)      as a result of a Substantiated Claim; or

         (b)      under clause 10; or

4.3      The Purchaser shall procure that as soon as practicable and in any
         event within 6 weeks after Completion the Company and PEL prepare the
         Completion Accounts. The Completion Accounts shall (subject to taking

         entirely consistent basis to the Accounts and on the basis of the same
         accounting policies, conventions standards and principles as the
         Accounts. The Purchaser shall also procure that PEL certifies the
         amount of the Net Assets. The cost of the preparation of the Completion
         Accounts and certification shall be borne by the Company and PEL as
         applicable. To facilitate the preparation of the Completion Accounts


                                       6




         the Purchaser shall procure a stock take of PEL is conducted within 10
         days of Completion to substantially verify the stock of PEL at
         Completion in accordance with normal industry practice and
         representatives of both the Vendor and the Purchaser shall be entitled
         to attend. Once prepared the Completion Accounts and PEL's
         certification of the Net Assets shall be submitted to the Vendor and
         Vendor's Auditors.

4.4      The parties shall disclose to the Company and PEL all relevant facts
         and information for the purposes of preparing the Completion Accounts
         and certifying the Net Assets. The Purchaser shall procure that the
         Company and PEL gives to the Vendor and the Vendor's Auditors all
         relevant facts information and documentation reasonably requested by
         them for the purpose of enabling them to review the draft Completion
         Accounts and the draft certification of Net Assets.

4.5      The draft Completion Accounts and the draft certificate of Net Assets
         shall be deemed to have been accepted by the Vendor unless the
         Purchaser receives notice to the contrary from the Vendor within 25
         Business Days of their being delivered to the Vendor pursuant to clause
         4.3 specifying (i) the item or items disputed (ii) their reasons and
         (iii) how the draft Completion Accounts and certificate of Net Assets
         should be adjusted (the "NOTICE"). The Purchaser shall permit the
         Vendor to have such access as the Vendor may reasonably request to the
         accounts working papers and relevant personnel relating to the
         preparation of the draft Completion Accounts and draft certification of
         Net Assets so as to enable the Vendor to evaluate the draft Completion
         Accounts and the draft certificate of the Net Assets delivered to it.
         If the Purchaser and the Vendor resolve the matters raised in the
         Notice within 10 working days following receipt by the Purchaser of the
         Notice the draft Completion Accounts and certificate of Net Assets
         (adjusted as agreed between the Purchaser and the Vendor) will be
         deemed to have been accepted by the parties as final. If the Purchaser
         and the Vendor are unable to reach agreement in such 10 working day
         period the matters in dispute may at the written election of the
         Purchaser or Vendor be referred to the decision of an independent
         chartered accountant ("Independent Accountant") to be appointed in
         default of agreement between the parties within 7 days of the election
         being made, by the President for the time being of the Institute of
         Chartered Accountants in England and Wales upon the application of
         either the Vendor or the Purchaser. The Independent Accountant shall
         act as an expert and not as an arbitrator (and neither the Arbitration
         Act 1996 or any earlier or later enactments on arbitration shall
         apply). The Independent Accountant's decision shall be final and
         binding (in the absence of manifest error) on the parties for all
         purposes of this agreement. The Completion Accounts and certificate of
         Net Assets as adjusted to reflect the Independent Accountant's decision
         shall be deemed to be accepted by the parties as final. The costs of
         the Independent Accountant shall be apportioned between the parties as
         the Independent Accountant shall decide but all parties shall bear
         their own costs for presenting their case to the Independent
         Accountant.

4.6      If the Net Assets as certified amount to less than (pound)2,520,000 the
         Purchase Price for the Sale Shares shall be reduced by the amount of
         that shortfall on a pound for pound basis. The amount of any reduction
         shall be limited to the Completion Payment. For the purpose of this
         clause 4.6 the Vendor and the Purchaser agree that the net assets of
         the Company as disclosed by the Completion Accounts of the Company when
         consolidated with the Net Assets of PEL should have no effect on the
         Net Assets of PEL. If for any reason such consolidation results in the
         Net Assets of PEL being reduced then the Net Assets of PEL for the
         purposes of this clause 4.6 shall be taken to be the lower figure which
         results from such consolidation.

                                       7




4.7      If the Net Assets amount to a sum in excess of (pound)2,520,000 the
         Purchase Price shall be increased by the amount of that excess on a
         pound for pound basis.

4.8      The Vendor or Purchaser (as the case may be) undertake to pay the
         amount of any reduction or increase (as the case may be) in the
         Purchase Price to the Vendor or the Purchaser (as the case may be) in
         cash within 14 days after the Completion Accounts and certificate of
         Net Assets are deemed to be accepted pursuant to this clause 4 and
         failing payment in full within the period of 14 days the balance
         outstanding from time to time shall bear interest (as well after as
         before judgment) from the date of deemed acceptance pursuant to this
         clause 4 until actual payment at the rate of 3 per cent per annum above
         the base rate of Barclays Bank PLC from time to time.

5.   COMPLETION

5.1      Completion shall take place on the Completion Date:

         (a)      at the offices of the Purchaser's Solicitors; or

         (b)      at any other place agreed in writing by the Vendor and the
                  Purchaser.

5.2      "COMPLETION DATE" means 15th March 2005 but if the Condition has not
         been satisfied in accordance with clause 2 on or before that date, it

                  and gives the Purchaser the undertakings set out in that
                  Schedule;

         (b)      that in the period between the date of this agreement and the
                  Completion Date it will use its reasonable endeavours to
                  procure that neither the Company nor its Subsidiary
                  deliberately do or deliberately omit to do anything which
                  would cause a breach of Warranty or make any Warranty untrue
                  or misleading were it to be repeated at Completion. The
                  Purchaser acknowledges that the Vendor will not be liable for
                  any breach of this clause 5.3(b) that is caused by
                  circumstances or actions outside of the reasonable control of
                  the Vendor or the Company or its Subsidiary.

5.4      At Completion the Vendor shall:

                  Schedule 3;

         (c)      deliver any other documents referred to in this agreement as

                  resolution of this agreement, and any other documents referred
                  to in this agreement as being required to be delivered by it;

         (f)      deliver written confirmation in the agreed form from the
                  Vendor confirming that upon receipt of the sum of
                  (pound)1,600,000 to be paid by the Purchaser to the Vendor on
                  behalf of the Company and its Subsidiary the Vendor shall

                  same to the Vendor in discharge of the Intelek Debt

5.5      At Completion the Purchaser shall:

         (a)      pay the Completion Payment less the Pension Retention by
                  telegraphic transfer to the Vendor's Solicitors and shall pay

                  Clause 8;

         (b)      lend to the Company the sum of (pound)1,600,000 in accordance
                  with the terms of the Loan Agreement which sum shall be

                  to in this agreement as being required to be delivered by it.

         the Purchaser does not comply with the requirements of clause 5.5 in
         each case in any material respect then the other party may, without
         prejudice to any other rights it has:

         (a)      proceed to Completion; or

         (b)      rescind this agreement.

5.7      As soon as possible after Completion, the Vendor shall send to the

         records, correspondence, documents, files, memoranda and other papers
         relating to the Company and its Subsidiary not required to be delivered
         at Completion, which are not kept at any of the Properties.

6.   WARRANTIES

6.1      The Purchaser is entering into this agreement on the basis of, and in
         reliance on, the Warranties.

                                       9




6.2      The Vendor warrants to the Purchaser as at the date of this agreement
         in the terms of the Warranties.

6.3      The Purchaser acknowledges that save in the case of fraud or fraudulent
         misrepresentation on the part of the Vendor it's sole remedy for breach
         of Warranty shall be in damages and the Purchaser shall have no right
         to rescind this agreement provided that if at any time before
         Completion the Purchaser becomes aware that a Warranty has been
         breached (or would have been breached had the Warranties been repeated
         at Completion) then the Purchaser may either proceed to Completion (in
         which case the Purchaser shall waive its right to bring a Claim in
         respect of such matter) or may as its sole remedy by notice in writing
         to the Vendor elect to rescind this agreement in which case this
         agreement shall cease to have effect immediately after that date and
         time except for the provisions set out in clause 2.3.

6.4      If at any time before or at Completion the Vendor becomes aware that a
         Warranty has been breached or would be breached had the Warranties been
         repeated at Completion it shall as soon as reasonably practicable
         notify the Purchaser in such detail in the possession of the Vendor to
         enable the Purchaser to make a reasonable assessment of the situation
         for the purposes of clause 6.3.

6.5      Warranties stated to be given "so far as the Vendor is aware" or "to
         the best of the Vendor's knowledge information and belief" or any
         similar such expression are deemed to be given after the Vendor has
         made all reasonable enquiries of the directors of the Company and its
         Subsidiary (but excluding Dr Brian Mazonas), Nicholas Stillwell, Guy
         Newham and Stuart Ellsbury, and the actual (as opposed to deemed or
         imputed) knowledge of each of the Vendor's Solicitors and the auditors
         of the Company and its Subsidiary (but not further or otherwise).

6.6      Each of the Warranties is separate and, unless otherwise specifically
         provided, is not limited by reference to any other Warranty or any
         other provision in this agreement.

6.7      Unless specifically stated to the contrary in this agreement the rights
         and remedies of the Purchaser in respect of any breach of the
         Warranties and the Tax Covenant shall not be affected by Completion, by
         any investigation made by it or on its behalf into the affairs of the
         Company or its Subsidiary, by its failing to exercise or delaying the
         exercise of any right or remedy, or by any other event or matter,
         except a specific and duly authorised written waiver or release, and no
         single or partial exercise of any right or remedy shall preclude any
         further or other exercise.

6.8      With the exception of the matters Disclosed, nothing the Purchaser
         knows, or which is a necessary consequence of facts within its
         knowledge, shall prevent or prejudice a Claim. Any document contained
         in the Disclosure Bundle shall only constitute a disclosure of the
         information contained in that document and not of any other matter or
         circumstances relating to or conclusion which might be drawn from the
         subject matter of that document which might give rise to a breach of
         any of the Warranties unless and to the extent that such other matter
         circumstances or conclusion is Disclosed expressly in the Disclosure
         Letter itself.

6.9      If the Purchaser is liable to pay Tax on any sum paid by the Vendor to
         the Purchaser as a result of a Substantiated Claim the amount so
         payable by the Vendor shall be increased by such amount as will ensure
         that (after payment of such Tax) the net receipt to the Purchaser is
         the same as it would have been were the payment by the Vendor not
         subject to Tax in the hands of the Purchaser.

                                       10




6.10     Clause 6.9 shall not apply to any Tax that the Purchaser is liable to
         pay to the extent that such Tax has already been taken into account in
         quantifying the liability of the Vendor under the Substantiated Claim.

6.11     If the Purchaser assigns the benefit of this agreement or any part
         thereof, the Vendor shall not be liable pursuant to clause 6.9, save to
         the extent that the Vendor would have been so liable had no such
         assignment occurred.

7.       LIMITATIONS ON CLAIMS

7.1      The definitions and rules of interpretation in this clause apply in
         this agreement.

         CLAIM: a claim under the Warranties;

         SHARE WARRANTY CLAIM: a claim under the Share Warranties;

         SUBSTANTIATED CLAIM: a Claim in respect of which liability is admitted
         by the party against whom such Claim is brought, or which has been
         adjudicated on by a Court of competent jurisdiction and no right of
         appeal lies in respect of such adjudication, or the parties are
         debarred by passage of time or otherwise from making an appeal.

         A Claim is CONNECTED with another Claim or Substantiated Claim if they
         all arise out of the occurrence of the same event or relate to the same
         subject matter.

7.2      This clause limits the liability of the Vendor in relation to any Claim
         and any claim under the Tax Covenant.

7.3      The aggregate liability of the Vendor for all Substantiated Claims and
         all claims under the Tax Covenant when taken together shall not exceed
         the Purchase Price (as adjusted in accordance with Clause 4) plus the
         amount of the Intelek Debt.

7.4      The Vendor shall not be liable for a Claim or a claim under the Tax
         Covenant unless:

         (a)      the amount of a Substantiated Claim, or of a series of
                  connected Substantiated Claims of which that Substantiated
                  Claim is one, exceeds (pound)5,000;

         (b)      the amount due in respect of a claim under the Tax Covenant
                  exceeds (pound)5,000;

         (c)      the amount of all Substantiated Claims and all claims under
                  the Tax Covenant that are not excluded under Clause 7.4(a) and
                  clause 7.4(b) when taken together, exceeds (pound)62,500 in
                  which case the whole amount (and not just the amount by which
                  the limit in this clause 7.4(c) is exceeded) is recoverable by
                  the Purchaser.

                                       11




7.5      The Vendor is not liable for any Claim to the extent that the Claim is
         in respect of a breach of Warranty and relates to matters Disclosed as
         permitted in this agreement.

7.6      The Vendor is not liable for a Claim or a claim under the Tax Covenant
         unless the Purchaser has given the Vendor notice in writing of the
         Claim or the claim under the Tax Covenant, specifying in reasonable
         detail the nature of the Claim or claim under the Tax Covenant and the
         amount claimed:

         (a)      in the case of a claim made under the Tax Warranties or the
                  Tax Covenant, within the period of seven years beginning with
                  the Completion Date; and

         (b)      in any other case, within the period of two years beginning
                  with the Completion Date,

         and the liability of the Vendor for any Claim or claim under the Tax
         Covenant specified in such notice shall absolutely determine and cease
         (unless the amount payable in respect of the relevant Claim or claim
         under the Tax Covenant has been agreed by the Vendor within three
         months of the date of such written notice) if legal proceedings have
         not been instituted in respect of such Claim or claim under the Tax
         Covenant by the due service of process on the Vendor within twelve
         months of such written notice.

7.7      The Vendor shall have no liability whatsoever in respect of any Share
         Warranty Claim to the extent that the claim arises or is increased as a
         result of any act or omission on the part of the Purchaser, the Company
         or its Subsidiary after Completion (otherwise than in the ordinary
         course of trading) or would not have arisen but for the passing of or
         any change in after the date of this agreement, any law, rule,
         regulation, interpretation of the law or administrative practice of any
         government, governmental department, agency or regulatory body or
         increase in the rates of Taxation or any imposition of new Taxation.

7.8      The Vendor shall have no liability whatsoever for any Claim or claim
         under the Tax Covenant to the extent that any loss occasioned to the
         Purchaser or the Company or its Subsidiary is covered by a right to
         make recovery or claim indemnity or by a policy of insurance in force
         on the date of this agreement and payment is made under such indemnity
         or policy without any increase in premium or change in terms on any
         renewal of such policy in consequence thereof.

7.9      The Vendor shall have no liability for any Share Warranty Claim:

         7.9.1    to the extent that provision, reserve or allowance has been
                  made in the Accounts or the Completion Accounts or was
                  specifically referred to in the notes to the Accounts or the
                  Completion Accounts in respect thereof or to the extent that
                  payment or discharge thereof has been taken into account
                  therein or in accordance with generally accepted accounting
                  principles has not been so taken account of, or referred to;
                  or

         7.9.2    to the extent that provision, reserve or allowance made in the
                  Accounts or the Management Accounts or the Completion Accounts
                  for any Taxation liability proves to be insufficient by reason
                  of any increase in the rates of Taxation or variation in the
                  method of applying, or calculating the rate of Taxation made
                  after Completion whether or not with retrospective effect; or

                                       12




         7.9.3    to the extent that the Purchaser fails to act in accordance
                  with the reasonable request or directions of the Vendor
                  pursuant to the provisions of clause 7.15.4 and the amount of
                  the liability is thereby increased beyond what it would have
                  been had the Purchaser acted in accordance with such request
                  or directions, then in respect of the amount of such increase.

7.10     If any potential Claim under the Share Warranties arises by reason of a
         liability which is contingent only, then the Vendor will not be under
         any obligation to make a payment in respect of such Claim until such
         time as the contingent liability ceases to be contingent and becomes
         actual however this shall not prevent or delay the Purchaser from
         pursuing the Claim in accordance with this agreement.

7.11     The Vendor shall not be liable in respect of any breach of the
         Warranties if, and to the extent that, the loss incurred is or has been
         included in any claim under the Tax Covenant which has been satisfied
         in cleared funds, nor shall the Vendor be liable in respect of a claim
         under the Tax Covenant if, and to the extent that, the amount claimed
         is or has been included in a breach of the Warranties which has been
         satisfied in cleared funds.

7.12     Nothing in this clause 7 applies to a Claim or a claim under the Tax
         Covenant that arises or is delayed as a result of dishonesty, fraud,
         wilful misconduct or wilful concealment by the Vendor, its agents or
         advisers.

7.13     The Vendor shall not plead the Limitation Act 1980 in respect of any
         claims made under the Tax Warranties or Tax Covenant up to seven years
         after the Completion Date.

7.14     If the Purchaser becomes aware of any event which might give rise to a
         Share Warranty Claim, the following provisions shall apply:

         7.14.1   the Purchaser shall as soon as reasonably practicable give
                  notice to the Vendor of the event and shall consult with the
                  Vendor in respect of the event;

         7.14.2   the Purchaser shall provide to the Vendor and to the Vendor's
                  professional advisers reasonable access to its personnel and
                  to the relevant assets, documents and records within the
                  Purchaser's power, possession or control for the purpose of
                  investigating the event and enabling the Vendor to take such
                  action as is referred to in clause 7.14.4 below;

         7.14.3   the Vendor (at its own expense) shall be entitled to take
                  copies of any relevant documents or records and photograph any
                  premises or assets as referred to in clause 7.14.2 above; and

         7.14.4   the Purchaser shall:

                  (a)      take such action and institute proceedings and give
                           such information and assistance as the Vendor may
                           reasonably request to dispute, resist, appeal,
                           compromise, defend, remedy or mitigate the event or
                           enforce against any person any rights of the
                           Purchaser in relation to the matter;

                  (b)      in connection with any proceedings related to the
                           event, use professional advisers approved (such
                           approval not to be unreasonably withheld) by the
                           Vendor; and

                                       13




                  (c)      take all reasonable steps to inform and consult with
                           the Vendor in respect of the conduct of those
                           proceedings and of any negotiations relating to them;

                  in each case subject to the Vendor indemnifying and securing
                  the Purchaser to its reasonable satisfaction against any
                  liability, costs, damages, penalties or expenses which may be
                  incurred as a result of any request by the Vendor, provided
                  that nothing in this clause shall require the Purchaser to
                  take any action which, in the reasonable opinion of the
                  Purchaser, could damage the commercial interests of the
                  Purchaser or the Company or its Subsidiary.

          For the avoidance of doubt the provisions of clause 7.14.4 do not
          apply to the pursuance by the Purchaser of any Claim under the Tax
          Warranties or claim under the Tax Covenant against the Vendor.

7.15     If at any time the Purchaser, the Company or its Subsidiary becomes
         entitled to recover from some other person (including any Taxation
         Authority) any sum in respect of any Share Warranty Claim then the
         Purchaser shall or shall procure that the Company or the Subsidiary
         shall:

         7.15.1   undertake all reasonable steps necessary to enforce such
                  recovery without being required to initiate litigation; and

         7.15.2   promptly supply all information which relates to such recovery
                  to the Vendor including details of any steps taken to enforce
                  such recovery and copies of all correspondence and documents
                  relating to the same.

7.16     If the Vendor pays to the Purchaser an amount in respect of a Share
         Warranty Claim and the Purchaser, the Company or its Subsidiary
         subsequently recovers from a third party an amount referable to the
         event giving rise to such claim then:

         7.16.1   if the amount paid by the Vendor in respect of the Share
                  Warranty Claim is more than the sum recovered, the Purchaser
                  shall promptly pay the Vendor the sum recovered less the costs
                  incurred by the Purchaser in recovering the same; and

         7.16.2   if the amount paid by the Vendor in respect of the Share
                  Warranty Claim is less than or equal to the sum recovered
                  (after deducting the costs incurred by the Purchaser in
                  recovering the same) the Purchaser shall promptly pay the
                  Vendor an amount equal to the amount paid by the Vendor.

7.17     If any amount is repaid to the Vendor by the Purchaser pursuant to
         clause 7.16.2 above, an amount equal to the amount so repaid shall be
         deemed never to have been paid by the Vendor for the purposes of
         paragraph 7.4 and accordingly shall not be treated as an amount in
         respect of which any liability has been incurred.

7.18     For the purposes of this paragraph the "sum recovered" means an amount
         equal to the amount recovered from the third party plus any repayment
         supplement in respect of the amount recovered from the third party
         under section 825 ICTA plus any interest in respect of the amount
         recovered from the third party, less the Purchaser's reasonable costs
         and expenses in pursuing such recovery.

7.19     Any payment to the Purchaser shall be deemed to be a reduction of the
         Purchase Price.

                                       14




7.20     Notwithstanding the terms of any other Warranty, the only Warranties
         given by the Vendor to the Purchaser in connection with the Environment
         and Environmental Matters (as such terms are defined in paragraph 19 of
         Schedule 4) are the Warranties set out in Warranty 19 of Schedule 4. No
         other Warranties in this agreement are given or may be interpreted as
         being given by the Vendor in connection with the Environment and
         Environmental Matters.

7.21     Notwithstanding the terms of any other Warranty, the only Warranties
         given by the Vendor to the Purchaser in connection with the Properties
         are the Warranties set out in Warranty 24 of Schedule 4. No other
         Warranties in this agreement are given or may be interpreted as being
         given by the Vendor in connection with the Properties.

7.22     Notwithstanding the terms of any other Warranty, the only Warranties
         given by the Vendor to the Purchaser in connection with the Accounts
         and the Management Accounts are the Warranties set out in Warranty 25
         of Schedule 4. No other Warranties in this agreement are given or may
         be interpreted as being given by the Vendor in connection with the
         Accounts and the Management Accounts.

7.23     No warranty given by the Vendor to the Purchaser in respect of the
         Environment, Environmental Matters, the Properties and/or the Accounts
         are given or may be interpreted as being given in respect of the
         subject matter of any Warranties set out in Schedule 4 other than the
         relevant Warranties at 19, 24 and 25 respectively.

8.       PENSION RETENTION

8.1      The Pension Retention shall on Completion be paid into the Retention
         Account which shall be opened by Hammonds, solicitors for and to the

8.2      The Vendor shall procure that as soon as practicable and in any event
         within 30 days after Completion, the Actuary shall be instructed to

         of the statutory shortfall in the Pension Scheme, assessed in
         accordance with Section 75 of the Pensions Act 1995 and the
         Occupational Pensions Scheme (Deficiency on Winding-up etc) Regulations
         1996, being the debt due to the Scheme from PEL at Completion (being
         the time at which PEL ceased to be an "Associated Employer" in terms of
         Rule 34.1.5 of the Rules of the Pension Scheme) ("the Certificate")

8.3      The Vendor and Intelek shall and the Purchaser shall procure that PEL
         shall disclose to the Actuary all relevant facts and information for
         the purposes of preparing the Certificate.

8.4      The Vendor shall use its reasonable endeavours to procure delivery to
         the Purchaser of a copy of the Certificate as soon as reasonably
         practicable following Completion and no later than 90 days following
         Completion as provided in clause 8.2 (the Vendor being deemed to have
         accepted the Certificate by virtue of procuring the delivery of the
         Certificate to the Purchaser).

                                       15

         Vendor shall forthwith instruct and authorise the Solicitors to

         specified in the Certificate from the Pension Retention provided that:

         (a)      in the event that the Pension Retention is insufficient to
                  meet the amount shown on the Certificate to be due from PEL to
                  the Pension Scheme the Vendor undertakes to the Purchaser to
                  pay the amount of any shortfall to the trustees of the Pension
                  Scheme in cash within 14 days of receipt of the Certificate by
                  the Purchaser;

         (b)      if the Certificate discloses that the amount of the debt due
                  from PEL to the Pension Scheme is less than the amount of the
                  Pension Retention the Solicitors shall instruct that the
                  balance of any monies after the payment to the trustees of the
                  Pension Scheme standing to the credit of the Retention Account
                  less all bank charges and costs and together with all accrued

10.      INDEMNITIES

10.1     The Saxon House Property is excluded from the sale and purchase of the
         Company and its Subsidiary and has been assigned from the Subsidiary to
         Intelek prior to the date of this agreement with the intention that the
         Purchaser, the Company and its Subsidiary shall have no liability
         whatsoever in respect of the Saxon House Property whether in respect of
         any matter which arose prior to or following the date of this
         agreement.

10.2     The Vendor undertakes to indemnify, and to keep indemnified, the

         proceedings, costs, expenses, penalties, legal and other professional

         proceedings, costs, expenses, penalties, legal and other professional
         fees and costs) which are suffered or incurred by any of them and which
         arise directly or indirectly in connection with the inability, for any

         the guarantee given by Intelek in favour of the Westridge Landlord in
         connection with the Westridge Property Lease and the refusal of the

         the avoidance of doubt the Purchaser and the Purchaser's Guarantor
         shall not be required to give any rent deposit, bank guarantee or other
         such security.

         Pension Scheme resulting from PEL's participation in the Pension Scheme
         prior to the Completion Date.

10.6     The Purchaser confirms on its own behalf and on behalf of PEL that
         (save as may be its duty and obligation in accordance with the law) it
         will not at any time procure, provoke, solicit, encourage or in any way
         assist with the formulation, origination or pursuit of any claim which
         may be brought or threatened against PEL by any person or body in
         relation to PEL's participation in the Pension Scheme or the provision,
         prior to the Completion Date, of any arrangements for pension or
         retirement benefits (whether benefits claimed as a result of actual
         pensionable service in the Pension Scheme or otherwise) by PEL.

10.7     In the event of any claim is brought or threatened by any person who,

                  known to the Purchaser or to PEL;

         (b)      not communicate or correspond (except for acknowledging
                  receipt and indicating the papers are being passed to Intelek
                  and the Trustee of the Pension Scheme) with any claimant or
                  any alleged or threatened claimant, save at such time, in such
                  manner and in such form as may be determined or expressly

                  Intelek are the only parties liable to members under the
                  Pension Scheme from the Completion Date and will, wherever
                  possible, direct the Communicator's enquiry to the Trustee of
                  the Pension Scheme and/or Intelek. PEL and the Purchaser will
                  forward without delay any correspondence from the Communicator
                  to the Trustees of the Pension Scheme and Intelek and consult
                  with them prior to taking any action.

         contained in clause 10.7 by itself and by PEL, Intelek will indemnify

                           the time of the offer or attempt, and was at the
                           Completion Date, a director, officer or employee
                           holding an executive or managerial position with the
                           Company or its Subsidiary; or

                  (ii)     procure or facilitate the making of any such offer or
                           attempt by any other person; or

                  business:

                  (i)      the words "Pascall"; or

                  (ii)     anything which is, in the reasonable opinion of the
                           Purchaser, capable of confusion with such words,

                  (iii)    any trade or service mark, business or domain name,

                  Subsidiary at any time during the 12 months immediately
                  preceding the Completion Date, if that solicitation or
                  enticement causes or would cause such supplier to cease
                  supplying, or materially reduce its supply of, those goods
                  and/or services to the Company or its Subsidiary.

11.2     Nothing in this clause 11 shall prevent the Vendor or any member of the
         Vendor's Group from:

         (a)      carrying on or being engaged or economically interested in any
                  business which at the Completion Date the Vendor or members of
                  the Vendor's Group carry on or are engaged in;

                                       18




         (b)      employing any person whose employment with the Company or its
                  Subsidiary is terminated after Completion by the Company or
                  its Subsidiary (as applicable) however in the case of Adele
                  McLachlan this exception shall not apply unless either (i) she
                  is offered employment by the Vendor or any member of the
                  Vendor's Group in a business division which is not engaged in
                  any business which is in direct competition with any part of
                  the Business or (ii) she is not offered employment until the
                  earlier of (1) the expiry of twelve months from the
                  termination of her employment by the Vendor or its Subsidiary
                  and (2) the expiry of the period in clause 11.1(c);

         (c)      advertising generally for staff;

         (d)      acquiring (whether by means of a share or asset purchase) as
                  part of a larger acquisition any interest in any business
                  which competes or which may compete with the Business
                  ("Competitive Business"):

                  provided that:

                  (i)      the acquisition of such Competitive Business is not a
                           principle reason for such acquisition;

                  (ii)     the Competitive Business shall not thereafter be
                           carried on under a corporate or trading name
                           incorporating "Pascall" or any colourable imitation
                           of "Pascall";

                  (iii)    the Competitive Business does not represent 15 per
                           cent. or more of the total consolidated turnover of
                           the business or assets being acquired.

11.3     The covenants in this clause 11 are intended for the benefit of the
         Purchaser, the Company and its Subsidiary and apply to actions carried
         out by the Vendor or any member of its Group in any capacity and
         whether directly or indirectly, on the Vendor's own behalf, on behalf
         of any other person or jointly with any other person.

11.4     Nothing in this clause 11 prevents the Vendor or any member of its
         Group from holding for investment purposes only:

         (a)      any units of any authorised unit trust; or

         (b)      not more than 5% of any class of shares or securities of any
                  company traded on any regulated stock exchange.

11.5     Each of the covenants in this clause 11 is a separate undertaking and
         shall be enforceable by the Purchaser separately and independently of
         its right to enforce any one or more of the other covenants contained
         in this clause 11. Each of the covenants in this clause 11 is
         considered fair and reasonable by the parties, but if any restriction
         is found to be unenforceable, but would be valid if any part of it were
         deleted or the period or area of application reduced, the restriction
         shall apply with such modifications as may be necessary to make it
         valid and enforceable.

11.6     The consideration for the undertakings contained in this clause 11 is
         included in the Purchase Price.

                  confidential; or

         (c)      information about the Purchaser's Group, the Vendor's Group or
                  the Company's Group that it receives from a source not

                  any obligation of confidence to any other person.

12.3     The Purchaser does not have to keep confidential or restrict its use
         of:

                  Completion; or

         (b)      information that is known to the Purchaser before the date of
                  this agreement and that it has acquired free from any
                  obligation of confidence to any other person.

                  officers of its Group as are reasonably necessary to advise on
                  this agreement, or to facilitate the Transaction, if the
                  disclosing party procures that the people to whom the
                  information is disclosed keep it confidential as if they were
                  that party; or

         (b)      with the written consent of all the other parties; or

                           employment are conducted; or

                  (v)      to protect the disclosing party's interest in any
                           legal proceedings,

         the disclosure before making it.

12.5     Each party shall supply any other party with any information about
         itself, its Group or this agreement as such other party may reasonably

         regulatory body or securities exchange to which such other party is
         subject.

12.6     No party shall make any announcement relating to this agreement or its
         subject matter without the prior written approval of all the other
         parties except as required by law or by any legal or regulatory
         authority.

13.      FURTHER ASSURANCE

         The Vendor shall (at its expense) promptly execute and deliver all such
         documents, and do all such things, as the Purchaser may from time to
         time reasonably require for the purpose of giving full effect to the
         provisions of this agreement.

14.      ASSIGNMENT

14.1     Except as provided otherwise in this agreement, no party may assign, or
         grant any Encumbrance or security interest over, any of its rights
         under this agreement or any document referred to in it.

14.2     Each party that has rights under this agreement is acting on its own
         behalf.

14.3     The Purchaser may assign its rights under this agreement (or any
         document referred to in this agreement) but not its obligations to a
         member of its Group to whom it transfers the Sale Shares.

14.4     If there is an assignment:

         (a)      the Vendor may discharge its obligations under this agreement
                  to the assignor until it receives notice of the assignment;
                  and

         (b)      the assignee may enforce this agreement as if it were a party
                  to it, but the Purchaser shall remain liable for any
                  obligations under this agreement.

15.      WHOLE AGREEMENT

15.1     This agreement, and any documents referred to in it, constitute the
         whole agreement between the parties and supersede any arrangements,
         understanding or previous agreement between them relating to the
         subject matter they cover.

15.2     Nothing in this clause 15 operates to limit or exclude any liability
         for fraud.

                                       21




15.3     The Purchaser acknowledges that it has not entered into this agreement
         in reliance upon any warranties, representations, covenants,
         undertakings, indemnities or other statements whatsoever other than
         those expressly set out in this agreement and the documents referred to
         herein.

16.      VARIATION AND WAIVER

16.1     Any variation of this agreement shall be in writing and signed by or on
         behalf of the parties.

16.2     Any waiver of any right under this agreement is only effective if it is
         in writing and it applies only to the party to whom the waiver is
         addressed and to the circumstances for which it is given and shall not
         prevent the party who has given the waiver from subsequently relying on
         the provision it has waived.

16.3     A party that waives a right in relation to one party, or takes or fails
         to take any action against that party, does not affect its rights in
         relation to any other party.

16.4     No failure to exercise or delay in exercising any right or remedy
         provided under this agreement or by law constitutes a waiver of such
         right or remedy or shall prevent any future exercise in whole or in
         part thereof.

16.5     No single or partial exercise of any right or remedy under this
         agreement shall preclude or restrict the further exercise of any such
         right or remedy.

16.6     Unless specifically provided otherwise, rights arising under this
         agreement are cumulative and do not exclude rights provided by law.

17.      COSTS

17.1     Unless otherwise provided, all costs in connection with the
         negotiation, preparation, execution and performance of this agreement,
         and any documents referred to in it, shall be borne by the party that
         incurred the costs.

18.      GUARANTEE PROVISIONS

18.1     In consideration of the Purchaser agreeing to purchase the Sale Shares,
         Intelek as primary obligor unconditionally and irrevocably:

         (a)      guarantees by way of continuing guarantee to the Purchaser the
                  payment when due of all amounts payable by the Vendor under
                  this agreement (the "Vendor Financial Obligations"); and

         (b)      agrees that each time the Vendor fails to pay a Vendor
                  Financial Obligation to the Purchaser when it is due under
                  this agreement, Intelek shall on demand (without requiring the
                  Purchaser first to take steps against the Vendor or any other
                  person) pay such Vendor Financial Obligation to the Purchaser.

                                       22

         payable by Intelek free and clear of all deductions or withholdings of
         any kind except for those required by law.

18.3     Intelek's obligation to guarantee the Vendor Financial Obligations
         shall not be affected by any matter or thing which but for this
         provision might operate to affect or prejudice those obligations
         including without limitation:

         (a)      any time or indulgence granted to, or composition with the
                  Vendor or any other person;

                  perfect or enforce this agreement against the Vendor;

         (c)      any claim or purported (or actual) right of set-off by the
                  Vendor against any member of the Purchaser's Group; or

         (d)      any unenforceability or invalidity of any obligation of the
                  Vendor so that this guarantee shall be construed as if there
                  were no such obligation.

18.4     The Purchaser may appropriate any sum paid by the Vendor, Intelek or
         any other person or recovered or received on account of the Vendor
         Financial Obligations as the Purchaser sees fit, whether or not towards
         those obligations.

18.5     Intelek will reimburse the Purchaser for all legal and other costs
         (including VAT) incurred by the Purchaser's Group in connection with
         the enforcement of this guarantee.

18.6     In consideration of the Vendor agreeing to sell the Sale Shares, the
         Purchaser's Guarantor as primary obligor unconditionally and
         irrevocably:

         (a)      guarantees by way of continuing guarantee to the Vendor
                  payment when due of all amounts payable by the Purchaser under
                  clause 10.3 of this agreement (the "Purchaser Financial
                  Obligations"); and

         (b)      agrees that each time the Purchaser fails to pay a Purchaser
                  Financial Obligation to the Vendor when it is due under clause
                  10.3 of this agreement, the Purchaser's Guarantor shall on
                  demand (without requiring the Vendor first to take steps
                  against the Purchaser or any other person) pay such Purchaser
                  Financial Obligation to the Vendor.

18.7     Each payment to be made by the Purchaser's Guarantor under this
         guarantee shall be payable by the Purchaser's Guarantor free and clear
         of all deductions or withholdings of any kind except for those required
         by law.

18.8     The Purchaser's Guarantor's obligation to guarantee the Purchaser
         Financial Obligations shall not be affected by any matter or thing
         which but for this provision might operate to affect or prejudice those
         obligations including without limitation:

                  Purchaser or any other person;

         (c)      any claim or purported (or actual) right of set-off by the
                  Purchaser against any member of the Vendor's Group; or

         (d)      any unenforceability or invalidity of any obligation of the
                  Purchaser so that this guarantee shall be construed as if
                  there were no such obligation.

18.9     The Vendor may appropriate any sum paid by the Purchaser, the
         Purchaser's Guarantor or any other person or recover or received on
         account of the Purchaser Financial Obligations as the Vendor sees fit,
         whether or not towards those obligations.

18.10    The Purchaser's Guarantor will reimburse the Vendor for all legal and
         other costs (including VAT) incurred by the Vendor's Group in
         connection with the enforcement of this guarantee.

         Due Date (or other due date for the payment of such sums), then, except
         to the extent that the Vendor's liability under paragraph 2 compensates
         the Purchaser for the late payment by virtue of it extending to
         interest and penalties, such sums shall bear interest (which shall


                                       66




         accrue from day to day after as well as before any judgment for the
         same) at the rate of 2% per annum over the base rate from time to time
         of Barclays Bank PLC or (in the absence thereof) at such similar rate
         as the recipient shall select from the day following the Due Date (or
         other due date for the payment of such sums) up to and including the
         day of actual payment of such sums.

4.       EXCLUSIONS

4.1      The Vendor shall not be liable under any Tax Warranty or any claim
         under the covenant contained in paragraph 2 in respect of any liability
         to the extent that:

o        a provision, allowance or reserve in respect thereof has been made in
         or its payment or discharge is reflected in, or taken into account in
         the Completion Accounts; or

o        the liability arises or is increased by reason of any increase in the
         rates of Tax or variation in the method of applying or calculating the
         rate of Tax made after the Completion Date whether or not with
         retrospective effect; or

o        the liability arises or is increased as a result of any change in the
         law or accounting practice or principle or the published practice of a
         Taxation Authority announced and coming into force after Completion
         (whether relating to rates of Tax or otherwise) or the withdrawal after
         Completion of any extra-statutory concession previously made by a
         Taxation Authority (whether or not the change purports to be effective
         retrospectively in whole or in part); or

o        the liability would not have arisen or would not have been increased
         but for a change after Completion in the bases, methods or policies of
         accounting of the Company or its Subsidiary or upon which the Company
         or its Subsidiary values its assets (other than a change made in order
         to comply with UK GAAP in force at Completion); or

o        the Purchaser is compensated for any such matter under any other
         provision of this agreement; or

o        the liability would not have arisen or would not have been increased
         but for a voluntary act, transaction or omission of the Purchaser, the
         Company or its Subsidiary after Completion being an act, transaction or
         omission which:


         (i) is not in the ordinary course of business of the Company or its
         Subsidiary; or


         (ii) the Company or its Subsidiary was not legally committed to do
         under a commitment that existed on or before Completion; or

                                       67




o        the Liability for Taxation is a De-grouping Charge which, whether by
         election or otherwise, is treated as accruing not to the Company or its
         Subsidiary but to the Vendor or any member of the Retained Group; or

o        the liability would not have arisen or would have been reduced or
         eliminated but for a failure or omission after Completion, on the part
         of the Company, its Subsidiary or the Purchaser, to make any claim,
         election, surrender or disclaimer or to give any notice or consent or
         to do any other thing under any enactment or regulation relating to Tax
         the making, giving or doing of which was taken into account in
         computing the provision for Tax in the Completion Accounts; or

o        the liability arises or is increased as a result of either the Company,
         the Subsidiary or the Purchaser failing to act in accordance with the
         provisions of paragraph 9 of this schedule; or

o        such liability arises as a result of: (i) any voluntary disclaimer by
         the Company or the Subsidiary after Completion of the whole or part of
         any capital allowances claimed before Completion or the entitlement to
         which was taken into account in preparing the Completion Accounts, or
         (ii) the voluntary revocation or revision by the Company or the
         Subsidiary after Completion of any Relief claimed or the entitlement to
         which was taken into account in preparation of the Completion Accounts;
         or

o        any Relief, other than a Purchaser's Relief is available to the Company
         or its Subsidiary (including by way of group relief from another
         company) to relieve or mitigate that liability.

5.       RECOVERY FROM THIRD PARTIES

5.1      Where the Purchaser, the Company or its Subsidiary is or becomes
         entitled to recover from some other person (including for the avoidance
         of doubt a Taxation Authority) not being the Purchaser, the Company or
         its Subsidiary or any other company within the Purchaser's Tax Group,
         any amount in respect of a Liability for Taxation, which has resulted
         in a payment being made by the Vendor under the Tax Warranties or the
         Tax Covenant, the Purchaser shall or shall procure that the Company or
         its Subsidiary shall:

o        notify the Vendor of its entitlement as soon as reasonably practicable;
         and

o        if required by the Vendor and, subject to the Purchaser, the Company or
         its Subsidiary being indemnified by the Vendor against any Tax that may
         be suffered on receipt of that amount and any costs and expenses
         incurred in recovering that amount, take or procure that the Company or
         its Subsidiary takes all reasonable steps to enforce that recovery
         against the person in question (keeping the Vendor fully informed of
         the progress of any action taken) save where in the Purchaser's
         reasonable opinion, to do so is likely to harm its or the Company's or
         its Subsidiary's commercial relationship with that or any other person
         to an extent as great or greater than the amount which is sought to be
         recovered.

                                       68




5.2      If the Purchaser, the Company or its Subsidiary recovers any amount
         referred to in paragraph 5.1, whether after taking any action requested
         by the Vendor or otherwise the Purchaser shall as soon as reasonably
         practicable account to the Vendor for the lesser of:

o        any amount recovered (including any related interest or related
         repayment supplement) less any Tax 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 Vendor);
         and

o        the amount paid by the Vendor under paragraph 2 or under any Tax
         Warranty in respect of the Liability for Taxation in question.

6.       OVER-PROVISIONS AND CORRESPONDING BENEFIT

6.1      If, before the seventh anniversary of the date of this agreement:

         (a)      any provision for Tax in the Completion Accounts proves to be
                  an over-provision;

         (b)      the amount by which any right to repayment of Tax which has
                  been treated (or, in accordance with generally accepted
                  accounting principles, could have been treated) as an asset in
                  the Completion Accounts proves to have been under-stated;

         (c)      a payment by the Vendor in respect of any Liability for
                  Taxation under the Tax Covenant or the Tax Warranties, or the
                  matter giving rise to such Liability for Taxation results in
                  the Company, the Subsidiary or the Purchaser receiving or
                  becoming entitled to any Relief (other than an Accounts
                  Relief) which they utilise (including by way of repayment of
                  Tax) (CORRESPONDING RELIEF),

             then an amount equal to such over-provision, under-stated right to
             repayment of Tax, or the Tax saved by the Corresponding Relief at
             the date such Corresponding Relief is utilised (RELEVANT AMOUNT),
             shall be dealt with in accordance with paragraph 6.2.

6.2      The Relevant Amount:

         (a)      shall first be set off against any payment then due from the
                  Vendor under the Tax Covenant or the Tax Warranties;

         (b)      to the extent there is an excess of the Relevant Amount after
                  any application of the same under paragraph 6.2 (a), a refund
                  shall be made to the Vendor of any previous payment or
                  payments made by the Vendor under the Tax Covenant or the Tax
                  Warranties and not previously refunded under this paragraph
                  6.2 (b) up to the amount of such excess; and

         (c)      to the extent that the excess referred to in paragraph 6.2 (b)
                  is not exhausted under that paragraph, the remainder of that
                  excess shall be carried forward and set off against any future
                  payment or payments which become due from the Vendor under the
                  Tax Covenant or the Tax Warranties.

                                       69




6.3      If the Purchaser, the Company or its Subsidiary becomes aware of any
         circumstances which shall or may give rise to the application of
         paragraph 6.1, the Purchaser shall or shall procure that the Company or
         its Subsidiary (as appropriate) shall as soon as reasonably practicable
         give written notice of the same to the Vendor.

6.4      The Vendor may require (at the Vendor's cost) the auditors for the time
         being of the Company or its Subsidiary to certify the existence and
         quantum of any Relevant Amount and the date on which the Corresponding
         Relief is utilised and, in the absence of manifest error, their
         decision shall be final and binding.

7.       PURCHASER'S COVENANT

7.1      The Purchaser covenants to pay to the Vendor an amount equal to:

         (a)      any liability or increased liability to Tax of the Vendor or
                  any person connected with the Vendor arising under or by
                  reference to section 767A or section 767AA of the ICTA 1988,
                  section 190 of the TCGA 1992 or section 132 of the FA 1988,
                  paragraph 68 of schedule 29 to the FA 2002, paragraph 8 of
                  schedule 34 to the FA 2002, paragraph 9 of schedule 35 to the
                  FA 2002, paragraphs 1 or 2 of schedule 39 to the FA 2002 or
                  Section 43 of the VATA 1994 by virtue of the non-payment of
                  Tax by the Company or the Subsidiary save that this paragraph
                  7.1 (a) shall not apply in respect of any Tax for which the
                  Vendor is liable to make (but has not yet made) payment to the
                  Purchaser under the Tax Covenant; and

         (b)      the reasonable costs and expenses of the Vendor or any person
                  connected to the Vendor in connection with any liability
                  referred to or in taking any action under this paragraph.

7.2      For the purposes of this paragraph, any reference to a liability to Tax
         shall include any liability to make a payment of Tax which would have
         arisen but for the utilisation of any Relief.

7.3      Paragraph 3 of this schedule shall apply to this paragraph 7 (with all
         necessary changes).

8.       CORPORATION TAX RETURNS

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

8.2      The Purchaser shall procure that the returns and computations referred
         to in paragraph 8.1 shall be authorised, signed and submitted to the
         relevant Taxation Authority without amendment or with such amendments
         as the Purchaser reasonably considers to be necessary and shall give
         the Vendor or its agent all such assistance as may reasonably be


                                       70




         required (at the Vendor's cost and expense) to prepare and agree those
         returns and computations with the relevant Taxation Authority provided
         that the Purchaser shall not be obliged to take any such action as is
         mentioned in this paragraph 8.2 in relation to any return that is not
         complete, true and accurate in all material respects.

8.3      The Vendor or its duly authorised agent shall at the Vendor'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 and its Subsidiary for all accounting
         periods ended on or prior to the Accounts Date provided that the Vendor
         shall not without the prior written consent of the Purchaser (not to be
         unreasonably withheld or delayed) transmit any communication (written
         or otherwise) to the relevant Taxation Authority or agree any matter
         with the relevant Taxation Authority.

8.4      The Purchaser shall and shall procure that the Company and its
         Subsidiary shall, at the Vendor's cost and expense,

         (a)      afford such access to their books, accounts and records as is
                  necessary and reasonable to enable the Vendor or its duly
                  authorised agent to prepare and agree the corporation tax
                  returns and computations of the Company and its Subsidiary for
                  all accounting periods ended on or before the Accounts Date
                  and conduct matters relating to them in accordance with this
                  paragraph 8;

         (b)      ensure that any correspondence which relates to the
                  corporation tax returns and computations of the Company and
                  its Subsidiary for all accounting periods ended on or before
                  the Accounts Date, if received by the Purchaser, the Company
                  or its Subsidiary (or their agents or advisers) is properly
                  copied to the Vendor.

8.5      The Vendor shall take all reasonable steps to ensure that the
         corporation tax returns and computations of the Company and its
         Subsidiary for all accounting periods ended on or before the Accounts
         Date are prepared and agreed with the relevant Taxation Authority as
         soon as reasonably possible.

8.6      The Purchaser or its duly authorised agent shall at the Purchaser's
         cost and expense prepare, or procure that the Company and/or its
         Subsidiary shall prepare the corporation tax returns and computations
         of the Company and its Subsidiary for the accounting period ending on
         the date of Completion, to the extent that the same have not been
         prepared before Completion, and submit them to the Vendor.

8.7      The Purchaser shall procure that the corporation tax returns referred
         to in paragraph 8.6 shall be authorised, signed and submitted to the
         relevant Taxation Authority without amendment or with such amendments
         as the Vendor shall suggest to make the returns and computations
         complete, true and accurate in all respects (provided that for the
         avoidance of doubt the Purchaser shall not have to take into account
         any amendments suggested by the Vendor unless by not making such
         amendment the returns and computations would not be true, complete and
         accurate in all respects) and shall give the Vendor or its agent all
         such assistance as may be reasonably required (at the Vendor's cost and
         expense) to review and amend those returns and computations provided
         that the Purchaser shall not be obliged to take any such action as is
         mentioned in this paragraph 8.7 in relation to any return that is not
         true and accurate in all material respects.

                                       71




8.8      The Vendor shall use its reasonable endeavours to ensure that the
         Company and its Subsidiary which is party to a group payment
         arrangement ("Group Payment Arrangement") with the Inland Revenue under
         section 36 of the Finance Act 1998 (as part of the group of companies
         of which the Vendor is a member) is as soon as reasonably practicable
         removed from the Group Payment Arrangement as provided for in the Group
         Payment Arrangement.

8.9      The Vendor shall use its reasonable endeavours to ensure that the
         nominated company (nominated for discharge of any liability to pay
         corporation tax under the Group Payment Arrangement) exercises its
         rights to apportion and re-apportion payments under the Group Payment
         Arrangement so far as reasonably practicable to ensure that any
         Liability for Taxation of the Company or its Subsidiary for which
         recovery would otherwise be available by the Purchaser under the Tax
         Covenant are fully and expeditiously discharged.

8.10     The Vendor will use its reasonable endeavours to ensure (to the extent
         permitted by law and for no consideration) that any Degrouping Charge
         for which recovery would otherwise be available by the Purchaser under
         the Tax Covenant or under the Tax Warranties is treated as accruing not
         to the Company or its Subsidiary but to the Vendor or a member of the
         Retained Group and the Purchaser will procure that the Company or its
         Subsidiary executes all claims, elections, consents or other documents
         relevant for that purpose.

8.11     For the avoidance of doubt:

o        where any matter relating to Tax gives rise to a Tax Claim, the
         provisions of paragraph 9 shall take precedence over the provisions of
         this paragraph 8; and

o        the provisions of this paragraph 8 shall not prejudice the rights of
         the Purchaser to make a claim under this Tax Covenant in respect of any
         Liability for Taxation.

9.       CONDUCT OF TAX CLAIMS

9.1      If the Purchaser, the Company or its Subsidiary becomes aware of a Tax
         Claim, the Purchaser shall give or procure that notice in writing is
         given to the Vendor as soon as is reasonably practicable of the Tax
         Claim, provided that if the Vendor receives any Tax Claim for whatever
         reason, it shall notify the Purchaser in writing as soon as is
         reasonably practicable and the Purchaser shall be deemed on receipt of
         such notification to have given the Vendor notice of such Tax Claim in
         accordance with the provisions of this paragraph 9 provided always that
         the giving of such notice shall not be a condition precedent to the
         Vendor's liability under the Tax Covenant.

                                       72




9.2      If the Vendor so requests in writing, the Purchaser shall provide the
         Vendor with all reasonable and relevant details, documents and
         information as the Vendor may reasonably request relating to the Tax
         Claim in the possession or under the control of the Purchaser or the
         Company or its Subsidiary.

9.3      Provided that the Vendor indemnifies the Purchaser and the Company or
         its Subsidiary (as appropriate) to the Purchaser's reasonable
         satisfaction against all liabilities, costs, damages or expenses which
         may be incurred thereby including any additional Liability for
         Taxation, the Purchaser shall take and shall procure that the Company
         or its Subsidiary shall take such action as the Vendor may reasonably
         request by notice in writing given to the Purchaser, the Company or its
         Subsidiary to negotiate, avoid, dispute, defend, resist, appeal or
         compromise any Tax Claim and any adjudication in respect thereof (such
         a Tax Claim where action is so requested being hereinafter referred to
         as a DISPUTE), provided that neither the Purchaser, the Company nor its
         Subsidiary shall be obliged to appeal or procure an appeal against any
         assessment to Tax raised on any of them if, the Vendor having been
         given written notice of the receipt of such assessment, the Purchaser
         has not within 14 days of the date of the notice, received instructions
         in writing from the Vendor to do so.

9.4      If:

o        the Vendor does not request the Purchaser to take or request the
         Purchaser to procure that, the Company or its Subsidiary takes any
         action under paragraph 9.3 or fails to indemnify the Purchaser, the
         Company or its Subsidiary to the Purchaser's reasonable satisfaction
         within a period of time (commencing with the date of the notice given
         to the Vendor) 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, resisting, appealing or compromising such Tax
         Claim, and which period will not in any event exceed a period of 21
         days; or

o        the Vendor (or the Company or its Subsidiary (in each case) before
         Completion) has been involved in a case involving fraudulent conduct in
         respect of the Liability for Taxation which is the subject matter of
         the Dispute; or

o        the Dispute involves an appeal against a determination by the Special
         Commissioners of the VAT and Duties Tribunal, unless the Vendor has
         obtained the opinion of Tax counsel of at least 5 years' standing that
         there is a reasonable prospect that the appeal will succeed,


the Purchaser, the Company or its Subsidiary shall have the conduct of the
Dispute absolutely (without prejudice to its rights under this Tax Covenant) and
shall be free to pay or settle the Tax Claim on such terms as are reasonable in
the circumstances.

9.5      Subject to paragraph 9.3, by agreement in writing between the Purchaser
         and the Vendor, the conduct of a Dispute may be delegated to the Vendor
         upon such terms as may be agreed from time to time between the
         Purchaser and the Vendor, provided that, unless the Purchaser and the
         Vendor specifically agree otherwise in writing, the following terms
         shall be deemed to be incorporated into any such agreement:

                                       73




o        the Purchaser, shall be entitled to see and keep copies of all
         correspondence or other written records of telephone conversations or
         meetings (in each case) with the relevant Taxation Authority relating
         to the Dispute and, in the event that there is no written record, shall
         be given an immediate report of any telephone conversation with any
         Taxation Authority to the extent that it relates to a Dispute;

o        the appointment by the Vendor of solicitors or other professional
         advisers to act in relation to the Dispute shall be subject to the
         approval of the Purchaser, such approval not to be unreasonably
         withheld or delayed;

o        all material written communications pertaining to the Dispute which are
         to be transmitted by the Vendor to the relevant Taxation Authority
         shall be first submitted to the Purchaser for approval and shall only
         be finally transmitted to the relevant Taxation Authority if such
         approval is given, which approval is not to be unreasonably withheld or
         delayed;

o        the Vendor shall make no settlement or compromise of the Dispute or
         agree any matter in the conduct of the Dispute which (in each case) is
         likely to affect the future liability to Tax of the Purchaser, the
         Company or its Subsidiary without the prior approval of the Purchaser,
         such approval not to be unreasonably withheld or delayed.

9.6      The Purchaser shall provide and shall procure that the Company or its
         Subsidiary provides to the Vendor and the Vendor's professional
         advisors reasonable access to premises and personnel and to any
         relevant assets, documents and records within their power, possession
         or control during normal business hours for the purpose of
         investigating the matters relating to the Tax Claim or Dispute and
         enabling the Vendor to take such action as is referred to in this
         paragraph 9.

9.7      Subject to the Vendor complying with the provisions of paragraph 9.3
         the Purchaser shall keep the Vendor fully informed of the conduct of
         the Dispute and shall forward to the Vendor copies of all such
         correspondence as is relevant to the Dispute received or sent by or to
         the Purchaser, the Company or its Subsidiary relating thereto.

9.8      Neither the Purchaser, the Company nor its Subsidiary shall be subject
         to any claim by or liability to the Vendor for non-compliance with any
         of the provisions of this paragraph 9 if the Purchaser, the Company or
         its Subsidiary has bona fide acted in accordance with the instructions
         of the Vendor.

10.      GROSSING UP

                                       74




10.1     All sums payable by the Vendor to the Purchaser under the Tax Covenant
         shall be paid free and clear of all deductions or withholdings
         whatsoever unless the deduction or withholding is required by law. If
         any deductions or withholdings are required by law to be made from any
         of the sums payable under the Tax Covenant, the Vendor shall pay to the
         Purchaser such sum as will, after the deduction or withholding has been
         made, leave the Purchaser with the same amount as it would have been
         entitled to receive in the absence of any such requirement to make a
         deduction or withholding.

10.2     If the Purchaser is required to pay Tax on any sum paid by the Vendor
         to the Purchaser under the Tax Covenant, the amount so payable by the
         Vendor shall be increased by such amount as will ensure that, after
         payment of such Tax, the Purchaser is left with a net sum equal to the
         sum it would have received had no such Tax been required to be paid.

10.3     If the Purchaser would, but for the availability of a Purchaser's
         Relief, incur a liability to pay Tax falling within paragraph 10.2, it
         shall be deemed for the purposes of that paragraph to have incurred and
         paid that liability.

10.4     If the Purchaser assigns the benefit of the Tax Covenant or any part of
         this agreement, the Vendor shall not be liable pursuant to paragraph
         10.1 or paragraph 10.2, save to the extent that the Vendor would have
         been so liable had no such assignment occurred.

11.      VALUE ADDED TAX GROUPS

11.1     The Purchaser shall procure that the Company shall notify HM Customs &
         Excise, as soon as reasonably practicable after Completion, that
         Pascall Electronics Systems Limieted and Pascall Microwave Limited are
         to be excluded from the value added tax group consisting of the
         Company, its Subsidiary, Pascall Electronics Systems Limited and
         Pascall Microwave Limited ("VAT GROUP") and that such exclusion is
         sought to have effect from not later than Completion. The Vendor shall
         provide the Purchaser with such information and assistance as the
         Purchaser may reasonably require for the purposes of this paragraph
         11.1.

12.      GROUP RELIEF

12.1     If the Vendor is liable to make any payment to the Purchaser under this
         Schedule, and such liability arises in relation to a Liability for
         Taxation which is capable of being mitigated or eliminated by the
         surrender of Group Relief, the Vendor shall be entitled to or to
         procure the surrender of Group Relief to the Company or its Subsidiary.
         Such surrender shall be made for no consideration and shall discharge
         the relevant liability of the Vendor under this Schedule.

12.2     If the Company or its Subsidiary holds any Relief (other than a
         Purchaser's Relief) which is capable of being surrendered as Group
         Relief by the Company or its Subsidiary to the Vendor or any company
         nominated by the Vendor, the Vendor shall be entitled to request such
         surrender to be made for no consideration.

                                       75




12.3     The Vendor and the Purchaser shall procure that all relevant claims,
         elections and surrenders and all other actions are taken as are
         required to effect the surrender and utilisation of the Group Relief
         referred to in this paragraph 12.
