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 giving such information will be borne by the Purchaser; and 13.4.2	the purpose of implementing the provisions of this Agreement in which case the cost of giving such information will be borne by the Vendor. 13.5	Not later than two business days after the Completion Date the Vendor shall send to each of the Employees a letter, in the agreed form, explaining that his employment has been transferred to the Purchaser pursuant to the Regulations. 13.6	The Vendor will, if so required by the Purchaser any time within 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. 13.9	After Completion, the Sellers shall provide the Purchaser with 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.

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.

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 or transmitted to the Party at the addresses first written above, provided that a Party may designate a different address by notice in accordance with this section.
