may be reasonably necessary in the circumstances and co-operate to 
enable the Sellers to bring or defend any proceedings in connection 
with any such Claim and in any event not to make any admission of 
liability in or otherwise to compromise any Claim with respect of 
any third party.

8.3	The maximum joint aggregate liability of the sellers to the 
Purchaser in respect of any and all Claims, is hereby limited to a 
sum equivalent to two thirds of the aggregate of the Consideration.

8.4	The Purchaser shall not bring any Claim in respect of any 
Warranty unless such individual claim exceeds 50,000 pounds sterling 
and until the aggregate of such claims exceeds 250,000 pounds sterling. 
These amounts are not intended to establish the standard of materiality 
under this Agreement.

8.5	Any amounts paid by either Seller in respect of any Claim shall 
be treated as a pound for pound reduction in the Consideration.

8.6	To the extent that the circumstances underlying any Claim are 
capable of being remedied then the Purchaser shall afford the Sellers 
a reasonable opportunity to remedy the same (which shall not however 
extend beyond 90 days after notice is given pursuant to Clause 8.1).

8.7	The Sellers shall not be liable in respect of any Claim to the 
extent that:-

8.7.1	the Purchaser caused or contributed to the same or to the acts 
and/or omissions giving rise to such Claim; and

8.7.2	the matter to which it relates is fully and promptly made good 
by the Sellers without cost to the Purchaser.

8.8	The Purchaser shall not be entitled to recover under any Claim 
if and to the extent that the facts or information upon which the Claim 
is based are fairly disclosed in the Disclosure Letter.

8.9	The Sellers shall not be liable to make any payment in respect 
of any Claim based on a contingent liability of the Purchaser unless and 
until the liability of the Purchaser becomes an actual liability.

8.10	The Sellers shall have no liability in respect of any Claim if 
and to the extent that it arises or is increased as a result of an 
increase in rates of taxation after Completion, or the passing of 
any legislation (or making of any subordinate legislation) with 
immediate or retrospective effect.

8.11	The Sellers shall have no liability in respect of any Claim to 
the extent that it relates to any loss for which the Purchaser is 
indemnified by insurance.

8.12	The Sellers shall have no liability in respect of any Claim to 
the extent that the circumstances, facts or events giving rise to 
the Claim would have been readily apparent to the Purchaser by 
virtue of the investigations into the Assets or the Site carried 
out on behalf of the Purchaser prior to the Completion Date.

8.13	Where the Purchaser is entitled to recover from some other 
person any sum in respect of any matter or event which could give 
rise to a Claim the Purchaser shall take all appropriate steps to 
recover that sum before making such Claim, and any sum recovered 
will reduce the amount of such Claim (and, in the event of the 
recovery being delayed until after such Claim has been satisfied 
by the Sellers, the sum recovered will be paid to the Sellers, 
after deduction of all reasonable costs and expenses of the recovery).

8.14	The Purchaser hereby relinquishes and waives any right of 
set-off or counter-claim, deduction or retention which the Purchaser 
might otherwise have in respect of any Claim or out of any payments 
which the Purchaser may be obliged to make (or procure to be made) 
to the Sellers (or any of them) pursuant to this Agreement or otherwise.

8.15	The Purchaser's sole remedy in respect of any Claim (other than 
any arising under Clause 6 or Clause 10) shall be damages.

8.16	In the event Completion does not occur (for whatever reason other 
than the refusal by a party to do so in circumstances where all 
conditions to Completion set out in Clause 3.12 have been satisfied 
or waived by the other parties), then it is agreed and acknowledged 
that no party shall have any liability to any other party whether 
for damages or otherwise.

9.1	On and from Completion the Purchaser shall indemnify and keep 
indemnified the Sellers from and against any claim, damages, costs, 
legal costs, orders or awards  and any other liability of whatever 
nature incurred by them in respect of the Assets and/or products sold 
by the Purchaser arising after the Completion Date whether arising in 
contract, tort or otherwise at law or under any statute or applicable 
European Union laws or directives.

9.2	On and from Completion the Sellers shall indemnify and keep 
indemnified the Purchaser from and against any claim, damages, costs, 
legal costs, orders or awards and any other liability of whatever 
nature incurred by it in respect of the Assets and/or products sold by 
the Sellers arising prior to the Completion Date whether arising in 
contract, tort or otherwise at law or under any statute or applicable 
European Union laws or directives.

9.3	This Clause 9 is without prejudice to any other express right or 
obligation of indemnification arising under this Agreement.

10.	CONFIDENTIALITY

10.1	Each Party undertakes to each other Party to keep the subject 
matter of this Agreement and any confidential or commercially 
sensitive information or knowledge relating to the transfer of the 
Business (whether or not so labelled and whether or not stored or 
recorded in any medium) belonging to or coming from each other Party 
as strictly confidential.

10.2	No Party shall disclose or permit the disclosure of any such 
information without the prior, written consent of the other Party.

10.3	Each Party shall use its best endeavours to procure compliance 
with this Clause 10 by its agents, employees or associates.

on the part of the Party making any relevant disclosure of the Party's 
information or which is required to be disclosed by compulsion of law 
or order of court (and then only so far as is so compelled).

10.5	No Party shall make any statement to the public concerning the 
subject matter of this Agreement except as is otherwise agreed, or as

exchange (and then subject to the Party requiring to make such 
statement first consulting the other).

Purchaser without the agreement of or novation by or consent to

Purchaser may require from time to time.

12.4	If such consent or novation is refused or otherwise not obtained

being present at any meetings;

13.1.4	immediately give to the Purchaser copies of all management 
accounts (including draft accounts) for periods in 1998 currently in 
the Vendor's possession and the Vendor shall pass to the Purchaser 
forthwith upon receipt copies of management accounts for subsequent

13.2	The Parties agree to co-operate and negotiate with each other 
in good faith between exchange of this Agreement and Completion in 
order to put arrangements in place to facilitate a smooth and efficient 
transfer of the Business from the Sellers to the Purchaser.  It is 
acknowledged that this is likely to include the following:-

13.2.1	the agreement on applicable terms and conditions in 
respect of pensions; and

13.2.2	the negotiation of a contract for the provision of 
services by the Vendor to the Purchaser after Completion.

Obligations After Completion

13.3	The Sellers undertake to pass to the Purchaser as soon as 
reasonably practicable after receipt any orders or inquiries in 
relation to the Business which they may receive at any time after 
Completion.

13.4	On and at any time after Completion the Sellers will use their 
reasonable endeavours to give or procure to be given to the Purchaser 
all such material information as is within their possession (including, 
without limitation, particulars of customers, suppliers and others who 
have dealt with the Sellers in connection with the Business) as the 
Purchaser may reasonably require for:-

13.4.1	the conduct of the Business in which case the cost of

agreed form, explaining that his employment has been transferred 
to the Purchaser pursuant to the Regulations.

30 business days after Completion and at the Purchaser's expense, send 
a circular in a form provided by the Vendor (such approval not to be 
unreasonably withheld or delayed) to persons who have had dealings 
with the Sellers in connection with the Business announcing the transfer 
to the Purchaser of the Business and the Assets. 

13.7	Pension Arrangements

13.7.1	the Vendor and the Purchaser shall, before the Completion, 
use their respective reasonable endeavours to agree the pension terms 
applicable to those Employees who are, immediately before April 5, 1998, 
contributory members of the Pension Scheme ("the Relevant Members");

13.7.2	the Purchaser shall establish or nominate a pension scheme 
("the Purchaser's Plan") on no less favorable terms than the Minteq UK 
Pension Plan details of which have been provided to the Sellers and 
invite relevant Members to join the Purchaser's Plan for future service;

13.7.3	the Vendor and the Purchaser shall each use their 
best endeavours:

1.	to procure that each Relevant Member shall have the opportunity 
to transfer his or her past service benefits to the Purchaser's Plan, 
and

2.	to procure from their respective actuaries a letter in agreed 
form setting out the amount which will enable the Purchaser's Plan to 
pay benefits to those Relevant Employees who enroll in the Purchaser's 
Plan, taking into account the effect of the past service of Relevant 
Members on the amount of future benefits.  The actuaries shall disclose 
the assumptions on which the calculation of such transfer amount is based.

The enrollment of Relevant Members in the Purchaser's Plan will include 
a credit for past service benefits, provided that a transfer is made 
from the trustees of the Pension Scheme to the trustees of the 
Purchaser's Plan in respect of that past service on the basis agreed 
by the actuaries of the Sellers and the Purchasers.

Such transfer will not entail any additional expense to the Sellers 
(other than the fees of their actuaries) and the Sellers shall have 
no obligation to pay any amount in excess of contributions required 
to be made pursuant to the rules of the Pension Scheme.

13.8	The Sellers shall, within 15 business days after Completion 
and at the Seller's expense, provide the Purchaser with a sworn, 
statutory declaration in respect of the Sellers' full and undisturbed 
possession since 1992 of the strip of land adjoining the towpath of the 
Stratford on Avon Canal.

all reasonable assistance in obtaining a license from the British 
Waterways Board authorising the discharge of clean surface water 
from the Site into the Stratford on Avon Canal.

13.10	Provided there exists no legal or contractual impediment 
the Sellers shall, at their own reasonable expense, provide that 
within 30 days after Completion, the name of the Vendor shall be 
changed so as not to include the word "Sturge" or any confusingly 
similar word or name.

14.	GENERAL

14.1	The Purchaser shall account to the Inland Revenue for 
(and shall indemnify the Sellers from any liability for) any stamp 
or other duty payable upon this Agreement or any agreement or 
conveyance executed by the Parties in contemplation hereof.

14.2	The Consideration is exclusive of Value Added Tax.

14.3	The Parties intend that the provisions of Section 49 of the 
Value Added Tax Act 1994 and Article 5 of the Value Added Tax 
(Special Provisions) Order 1995 shall apply to the sale of the Assets 
and the Site and, accordingly, no VAT shall be charged by the Sellers 
on them.  The Sellers and the Purchaser shall each promptly following 
Completion inform their respective VAT Offices of the sale and purchase 
under this Agreement, complete all relevant forms for VAT purposes 
relating to such sale and purchase and take all reasonable steps to 
ensure that the sale of the Assets is treated neither as a supply of 
goods nor a supply of services for the purposes of VAT but as the 
transfer of a going concern.  In the event that it is at any time 
etermined by H. M. Customs & Excise or, on appeal, by the Tribunal or 
the Court that Section 49 of the Value Added Tax Act 1994 and Article 5 
of the Value Added Tax (Special Provisions) Order 1995 do not apply to 
the sale of the Assets or the Site or any part of them, the Purchaser 
shall pay to the Vendor or the Guarantor (as the case may be), the 
amount of the VAT in question on the later of the business day before 
such amount is due to be paid by the relevant Seller to Customs & Excise 
and the day on which the relevant Seller delivers to the Purchaser, 
a valid VAT invoice or invoices in respect thereof.

14.4	The Purchaser undertakes to keep all of the Documents which 
relate to the tax and accounting affairs of the Business secure and 
complete for not less than six years after the Completion Date and to 
allow the Sellers access to them at all reasonable times during this 
period for the purposes of inspection and to take copies thereof 
where necessary.

14.5	The Parties shall do and give all such deeds and further 
assurances as may be reasonable to give effect to each of the 
assignments and transactions contemplated herein (the costs of 
the preparation, execution and filing of all such deeds and assurances 
and any registrations, filings and notifications with or to any 
regulatory body to be borne by the Purchaser).

14.6	Save as is expressly provided otherwise, each Party shall bear 
its own costs in connection with the negotiation or preparation or 
completion of this Agreement.

14.7	Each Party unconditionally waives any rights it may have to 
claim damages against the other on the basis of any written or oral 
statement made by the other (whether made carelessly or not) not set 
out or referred to in this Agreement (or for breach of any warranty 
given by the other not so set out or referred to) unless such statement 
or warranty was made or given fraudulently or with a reckless disregard 
for its truthfulness.

14.8	Each Party unconditionally waives any rights it may have to 
rescind or to seek to rescind this Agreement on the basis of any 
written or oral statement made by the other (including any Warranty) 
(whether made carelessly or not) whether or not such statement is set 
out or referred to in this Agreement unless such statement was made 
fraudulently or with a reckless disregard for its truthfulness.

14.9	The parties agree to execute, complete and keep the original 
and all executed counterparts of this Agreement outside the 
United Kingdom at all times, except that a Party shall be entitled 
to bring the original or counterpart into the United Kingdom where:

(i)	it is a mandatory legal requirement to produce the document 
in any judicial or arbitration proceedings:

(ii)	the document is to be used as evidence in legal or arbitration 
proceedings and the judge or arbitrator responsible for the 
determination of the proceedings has ruled that a certified 
copy cannot be produced as adequate evidence; or

(iii)	the document is required by the Inland Revenue or HM Customs 
to determine the liability of either of the Sellers to taxation 
arising from the execution of the document or performance of the Agreement.

PROVIDED ALWAYS that the Sellers shall use all reasonable efforts to 
procure the agreement of the person or authority requiring production 
of the document to accept a certified copy in its place.
		
15.	JURISDICTION

15.1	The Parties hereby submit to the exclusive jurisdiction of the 
English Courts but without prejudice to the enforcement or execution 
of any judgment, order or award thereof, or to any interlocutory or 
injunctive proceedings in any other jurisdiction.  This Clause 15.1 
is without prejudice to Clause 15.3.

15.2	For the purposes of Order 10, Rule 3, Rules of the Supreme Court 
(or any modification thereof), the Parties agree that any process or 
other legal proceedings may be served on any of them by leaving a copy 
thereof or by posting a copy thereof addressed to a Party at its 
address first stated above.

15.3	The Parties hereby agree that they shall use their reasonable 
endeavours to seek to settle any dispute and to negotiate the same 
in good faith prior to instituting any proceedings.

15.4	Any notice permitted or required to be given under this 
Agreement shall be in writing and shall be given, posted, delivered
