(a) The obligations of the Vendor and the Purchaser under this Agreement (other than those contained in this Clause 2, Clause 8 and Clauses 26 to 28 and Clauses 30 to 40 which are unconditional) are conditional in all respects upon:

(i) the European Commission having issued a decision under Council Regulation (EC) No. 139/2004 (the "Merger Regulation") (or being deemed to have done so under Article 10(6) of the Merger Regulation) declaring the purchase of the Shares by the Purchaser compatible with the common market and/or, if any aspect of the acquisition is referred to a competent authority of a European Union or EFTA State or more than one such competent authorities under Article 9 of the Merger Regulation, confirmation having been received from each such competent authority that the purchase of the Shares by the Purchaser may proceed;

(ii) the receipt of evidence in a form and substance reasonably satisfactory to the Vendor and the Purchaser that, if required, all other regulatory consents and appraisals have been received, all filings have been made and all waiting periods have expired or been terminated in relation to the transactions contemplated in this Agreement pursuant to the applicable laws of any jurisdiction, including without limitation, the Hart Scott Rodino Anti-Trust Improvements Act of 1976 (as amended) of the United States of America;

(iii) either (a) no factual information that has not been fairly disclosed in the Disclosure Letter or the Data Room or that has not been delivered prior to the date hereof to the Purchaser's Solicitors expressly in the context of their review of the LDPE Technology Licence (such information being referred to in this Clause 2(a)(iii) as "new information") coming to the attention of either the Vendor or the Purchaser which relates to the period prior to the date hereof and which is relevant to the interpretation of the LDPE Technology Licence (and for the avoidance of doubt, ExxonMobil's reaction, of itself (as opposed to any new information put forward as the basis for, or in connection with such reaction), to the transactions contemplated by this Agreement will not be treated as a fact which is relevant to the interpretation of the LDPE Technology Licence), or (b) if such new information does come to the attention of the Vendor or the Purchaser, the obtaining of an opinion pursuant to Clause 9(b) or Clause 9(c) in relation to the LDPE Technology Licence which gives the confirmations contemplated by Clause 9(b)(ii) or Clause 9(c)(ii) (as the case may be);

(vii) the Vendor having complied in all material respects with its obligations under Clause 8 (or, if the Vendor has failed to comply in all material respects with such obligations, such failure not having been remedied on or before Completion);

(viii) no event or circumstance having occurred or been discovered which, if the Purchaser were to proceed to Completion, would entitle the Purchaser to bring a claim (or claims

(ix) no event or circumstance, other than an event or circumstance which is constituted by matters which pertain either to general economic conditions affecting the United Kingdom, European or world economy or to conditions in the petrochemicals industry generally, having occurred or been discovered which, if the Warranties were repeated immediately before Completion, would have constituted a breach of Warranty and which would have (or would be more than likely to have) a material adverse effect on the Company; and

(x) no order or judgment of any court or governmental, statutory or regulatory body having been issued or made prior to Completion, and no legal or regulatory requirement remaining to be satisfied, which has the effect of making unlawful or otherwise prohibiting either (i) the transfer of the Shares to the Purchaser or (ii) the transactions contemplated by this Agreement other than the transfer of the Shares to the Purchaser (in the case of (ii) only) to a material extent.

(b) The Vendor shall use all reasonable endeavours promptly to procure the satisfaction of the conditions set out in sub-clause (a)(i), (ii), (iv), (v), (vii) and (x). The Purchaser shall use all reasonable endeavours promptly to procure the satisfaction of the conditions set out in sub-clause (a)(i), (ii), (iv), and (x)

(i) providing information which is requested by any such governmental or regulatory body or other person;

(ii) co-operating with and assisting the Vendor and the Company to obtain any consents, approvals or actions of any governmental or regulatory body or other person required by either the Vendor or the Company;

(iii) notifying the Vendor, and providing copies, of any communications from any such governmental or regulatory body or other person in relation to obtaining any such consent, approval or action;

(iv) disclosing to the Vendor or the Vendor's advisers any information relating to the Purchaser or the Purchaser's Group as may be reasonably required by the Vendor for the purposes of obtaining any such consent, approval or action; and

(v) where requested by the Vendor, providing the Vendor (or advisers nominated by the Vendor) with draft copies of all submissions and communications to governmental or regulatory bodies or other persons at such time as will allow the Vendor a reasonable opportunity to provide comments on such submissions and communications before they are submitted or sent and amending all such submissions or communications in accordance with the reasonable requirements of the Vendor (or such nominated advisers) and providing the Vendor (or such nominated advisers) with copies of all such submissions and communications in the form submitted or sent.

(d) Without prejudice to sub-clause (b) above, the Vendor shall, so far as is reasonably necessary, and as promptly as practicable, provide the Purchaser with such reasonable assistance as the Purchaser may reasonably require for the purpose of fulfilling the Purchaser's obligations under sub-clause (c) above, including without limitation:

(i) providing information which is requested by any governmental or regulatory body or other persons whose consents, approvals or other actions are required in order to permit completion of the transactions contemplated by this Agreement, including information which the Purchaser reasonably considers necessary for it to make all notifications and filings to any such body or person;

(e) Nothing in this Clause 2 shall impose any obligation on any party to:

(i) enter into agreements to hold separate or dispose of any part of the businesses of the Vendor's Group or the Purchaser's Group (as the case may be); or

(ii) enter into agreements to supply any products; or

(iii) enter into agreements other than on commercially reasonable terms; or

(iv) enter into any consent judgment, consent agreement or undertaking in relation to any part of its business which competes with all or part of the Acquired Business; or

(v) disclose confidential information relating to its financial or business affairs to any person other than to another party to this Agreement or such other party's legal advisors or to governmental or regulatory authorities; or

(vi) where that party is obliged under this Clause 2 to disclose confidential information relating to its financial or business affairs to another party to this Agreement or its legal advisers, disclose such information beyond the extent necessary to enable such other party to comply with its obligations under this Clause 2 (which may, by way of example, involve disclosure of specific information to legal advisers on the basis that it will not be disclosed to such other party).

(f) The conditions set out in sub-clauses (a)(i), (ii), (iv), (v), (viii) and (x) may only be waived by the written agreement of each party to this Agreement. The conditions set out in sub-clauses (a)(iii), (vi), (vii) and (ix) may be waived in writing by the Purchaser alone. For the avoidance of doubt, any such waiver by the Purchaser shall not in any respect constitute a waiver by the Purchaser of any rights which it might have in respect of the circumstances giving rise to the non-satisfaction of the relevant condition, including but not limited to any right which it may have to bring a claim for breach of warranty in the case of the non-satisfaction of the conditions set out in sub-clauses (a)(viii) or (ix), provided that if new information (as defined in sub-clause (a)(iii)) emerges in relation to the LDPE Technology Licence and the Purchaser waives the condition set out in sub-clause (a)(iii), that new information shall be deemed to have been fairly disclosed in the Disclosure Letter and the Purchaser's rights to bring a claim for breach of Warranty in respect of the Warranties contained in paragraph 49 or, insofar as it relates to the LDPE Technology Licence, paragraph 51(A), of Schedule 3 shall be limited accordingly.

(g) If any fact which makes any of the conditions set out in sub-clause (a) incapable of being satisfied on or before the relevant Termination Date comes to the knowledge of any party at any time prior to Completion then that party shall notify the others of that fact and any party shall be entitled to treat this Agreement as terminated by written notice to the others provided that (i) no party shall be entitled to treat this Agreement as terminated where that party is in breach of its obligations under this Clause where such breach has contributed materially to the non-satisfaction of the condition and (ii) no party other than the Purchaser or the Purchaser's Guarantor shall be entitled to treat this Agreement as terminated by reference to the incapability of satisfaction of any of the conditions the satisfaction of which may be waived by the Purchaser alone, unless and until the Purchaser states in writing that it will not waive that condition.

(h) If the conditions set out in sub-clause (a) are not satisfied or waived in accordance with sub-clause (f) on or before the relevant Termination Date, this Agreement shall automatically terminate.

(i) If this Agreement is terminated or terminates pursuant to this Clause then the obligations of each party under this Agreement (except for obligations under this Clause 2 and Clauses 26 to 28 and Clauses 30 to 40) shall automatically terminate provided that the rights and liabilities of

the parties which have accrued prior to termination shall subsist and provided further that, for the avoidance of doubt, no rights and liabilities in respect of the Warranties or in respect of any breach of Clause 8 shall subsist following such termination. The only remedy available to any party (i) for another party's failure to use all reasonable endeavours pursuant to sub-clause 2(b), or (ii) where the failure to satisfy a condition under Clause 2(a) has been caused by the Vendor's breach of Clause 8 or a breach of a Warranty, shall in either case be compensation for wasted costs and expenses incurred in connection with negotiating this Agreement and carrying out due diligence on the Company, and such remedy shall only be available to the extent that such other party could reasonably have prevented such failure or breach.

3. SALE AND PURCHASE

(a) On the terms set out in this Agreement, the Vendor shall sell and the Purchaser shall purchase the legal and beneficial ownership of the Shares as at and with effect from Completion together with all rights attached or accruing to them at Completion.

(b) The Vendor undertakes that the Shares shall be transferred at Completion free from all liens, charges and encumbrances and all other rights in favour of or exercisable by third parties.

(c) The Purchaser shall be entitled from Completion to exercise all rights attached or accruing to the Shares, including, without limitation, the right to receive all dividends or distributions or any return of capital declared, paid or made by the Company, on or after the Completion Date.

(d) The Vendor (for itself and on behalf of any other relevant member of the Vendor's Group) waives all rights of pre-emption over the Shares, howsoever conferred and shall procure that no later than Completion all such rights of pre-emption and any other similar or comparable rights over or in respect of the Shares conferred upon any other person are waived so as to permit the sale and purchase of the Shares hereunder.

(e) For the avoidance of doubt, Part I of the Law of Property (Miscellaneous Provisions) Act 1994 shall not apply for the purpose of this Clause 3.

4. CONSIDERATION

(a) The initial aggregate consideration payable at Completion for the sale of the Shares shall be the payment by the Purchaser to the Vendor of the Debt Free Price:

(i) plus the Provisional Cash Amount;

(ii) less the aggregate of the Provisional Third Party Debt Amount and the Provisional Intra-Group Debt Amount;

(iii) either:

(A) plus the difference between the Provisional Working Capital and the Target Working Capital, if the Provisional Working Capital is greater than the Target Working Capital; or

(B) less the difference between the Provisional Working Capital and the Target Working Capital, if the Provisional Working Capital is less than the Target Working Capital;

(iv) either:

(A) less the amount (if any) by which the Provisional Actual Expenditure is less than $208,000,000; or

(B) plus the amount (if any) by which the Provisional Actual Expenditure is more than $208,000,000; and

(v) less the amount (if any) by which the Provisional Forecast Expenditure is more than $360,000,000,

provided the adjustments in (i), (ii), (iv) and (v) (but excluding the adjustment in (iv)(B)) above shall only apply to the extent that they do not result in an amount over the Debt Free Price being payable,

(the "Initial Cash Consideration") (such payment to be made in accordance with Clause 10).

Between the date of this Agreement and Completion, the parties will procure that their respective accountants or financial personnel will meet with a view to agreeing the methodology for determining the provisional amounts specified in (i) to (v) above with a view to ensuring that those provisional amounts are as accurate as possible. Where the parties do not agree prior to Completion on a methodology for determining any such provisional amount, the relevant provisional amount shall be as estimated in good faith by the Vendor. Where the parties agree on a methodology in relation to any such provisional amount prior to Completion, the Vendor shall use such methodology in estimating such provisional amount.

Not less than 2 Business Days prior to the Completion Date the Vendor will notify the Purchaser in writing of its estimates of the Provisional Cash Amount, the Provisional Third Party Debt Amount, the Provisional Intra-Group Debt Amount, the Provisional Working Capital, the Provisional Actual Expenditure and the Provisional Forecast Expenditure together with supporting documentation and a statement signed by the CFO (Chief Financial Officer) of the Vendor's Guarantor confirming that the estimates have been determined in good faith and are believed by him (without assuming personal liability) to be fair.

(b) Following determination of the Final Third Party Debt Amount, the Final Intra-Group Debt Amount, the Final Cash Amount, the Actual Expenditure, the Forecast Expenditure and the Completion Working Capital, in accordance with the provisions of Clauses 5, 6 and 7 and Schedule 10, the Initial Cash Consideration shall be adjusted to take account of payments made pursuant to those Clauses in order to determine the final aggregate cash consideration for the sale of the Shares (the "Final Cash Consideration"), provided that:

(i) the adjustments to the Initial Cash Consideration pursuant to Clauses 5(a)(i) to (iv), 6 and 7 and Schedule 10 (excluding any adjustment under paragraph 3(A)(i) of Schedule 10 and any interest under Clauses 5(a) or 6(b)) shall apply only to the extent

that they do not cause the Final Cash Consideration (excluding any reduction by virtue of paragraph 14 of Schedule 4) to exceed the Debt Free Price; and

(ii) any upward adjustment to the Initial Cash Consideration in relation to Actual Expenditure pursuant to paragraph 3(A)(i) of Schedule 10 or in relation to Completion Working Capital pursuant to Clause 5(a)(v) and (vi) or in relation to interest under Clauses 5(a) or 6(b) will apply regardless of the extent it causes the Final Cash Consideration to exceed the Debt Free Price.

(c) The Initial Cash Consideration, the Final Cash Consideration, any payments made pursuant to Clauses 5, 6 and 7 and Schedule 10, and any other payment made under this Agreement to the Vendor shall be exclusive of any amount in respect of VAT.

5. CASH/THIRD PARTY DEBT/WORKING CAPITAL ADJUSTMENT

(a) Subject to Clause 4(b), if:

(i) the Final Cash Amount is greater than the Provisional Cash Amount, then the Purchaser shall pay to the Vendor an amount equal to the difference;

(ii) the Final Cash Amount is less than the Provisional Cash Amount, then the Vendor shall pay to the Purchaser an amount equal to the difference;

(iii) the Final Third Party Debt Amount is greater than the Provisional Third Party Debt Amount, then the Vendor shall pay to the Purchaser an amount equal to the difference;

(iv) the Final Third Party Debt Amount is less than the Provisional Third Party Debt Amount, then the Purchaser shall pay to the Vendor an amount equal to the difference;

(v) the Completion Working Capital is greater than the Target Working Capital, then the Purchaser shall pay to the Vendor an amount equal to the difference,

(A) less the amount paid by the Purchaser to the Vendor pursuant to Clause 4(a)(iii)(A) (if any); or

(B) plus the amount deducted from the Initial Cash Consideration pursuant to Clause 4(a)(iii)(B) (if any);

(vi) the Completion Working Capital is less than the Target Working Capital, then the Vendor shall pay to the Purchaser an amount equal to the difference,

(A) less the amount deducted from the Initial Cash Consideration pursuant to Clause 4(a)(iii)(B) (if any); or

(B) plus the amount paid by the Purchaser to the Vendor pursuant to Clause 4(a)(iii)(A) (if any),

provided that the above payments shall be netted-off against each other and, within five Business Days of the final agreement or determination of the Final Cash Amount, the Final Third Party Debt Amount and the Completion Working Capital, the Vendor shall be obliged to pay the Purchaser the net balance or the Purchaser shall be obliged to pay the Vendor the net balance, as the case may be, together with an amount equal to interest on the net balance at the Agreed Rate (accrued daily) for the period from the Completion Date to the date of payment. Any payment under this sub-clause 5(a) shall constitute an adjustment to the Initial Cash Consideration.

(b) Within 20 Business Days of Completion, the Vendor shall notify the Purchaser of its calculation of the Final Cash Amount, the Final Third Party Debt Amount and the Completion Working Capital together with reasonably detailed supporting documentation. The Purchaser shall notify the Vendor of any dispute in relation to any such amount within 30 Business Days of the date of the Vendor's notice and shall provide reasonable details of the grounds for disputing such amount and (so far as reasonably practicable) of the amount which the Purchaser believes in good faith to be the correct amount for such Final Cash Amount, Final Third Party Debt Amount or Completion Working Capital. The Purchaser shall be deemed to have agreed to the Final Cash Amount, Final Third Party Debt Amount or Completion Working Capital (as the case may be) which it does not so dispute within 30 Business Days of the date of the Vendor's notice.

(c) If the Purchaser serves notice of a dispute in accordance with sub-clause 5(b), and if the Vendor and the Purchaser are unable to agree any of the Final Cash Amount, Final Third Party Debt Amount or Completion Working Capital within 15 Business Days of the date of the Purchaser's notice referred to in sub-clause 5(b) (or such longer period as they may agree), then the determination of such Final Cash Amount, Final Third Party Debt Amount or Completion Working Capital shall be referred for determination to the Expert who shall be instructed to notify both the Vendor and the Purchaser of his determination and of the reasons for it within 20 Business Days of such referral. In making his determination the Expert shall act as expert and not arbitrator and his determination shall, in the absence of manifest error, be final and binding and deemed to have been accepted and approved by the Vendor and the Purchaser and shall be deemed to constitute the Final Cash Amount, Final Third Party Debt Amount or Completion Working Capital (as the case may be) for all purposes of this Agreement. The fees and costs of the Expert incurred under this Clause 5 shall be paid as to one-half by the Vendor and one-half by the Purchaser unless otherwise directed by the Expert (who shall have the authority to make such direction if he deems it equitable).

(d) For the purposes of determining and agreeing the Final Cash Amount, Final Third Party Debt Amount or Completion Working Capital the Purchaser shall, and shall procure that the Company shall, give the Vendor and the Expert reasonable access at all reasonable times to all books and records relating to such Final Cash Amount, Final Third Party Debt Amount or Completion Working Capital in their respective possession or control and the Vendor shall as soon as reasonably practicable respond to all reasonable enquiries and provide such relevant information reasonably within its control as may be reasonably requested by the Purchaser and/or the Expert for that purpose.

(e) In determining the Final Cash Amount, the Final Third Party Debt Amount and Completion Working Capital the definitions, principles, policies, procedures and methods and practices of accounting set out in Attachment IV shall be applied.

(f) All payments referred to in this Clause 5 shall be made in immediately available funds to the Purchaser's Bank Account or (as the case may be) the Vendor's Bank Account.

(g) The Vendor undertakes that it will identify to the Purchaser no later than the time of delivery of the Vendor's notice referred to in Clause 5(b) all items which are properly to be included in the Final Third Party Debt Amount.

6. INTRA-GROUP DEBTS

(a) The Purchaser shall immediately prior to Completion advance to the Company on loan a sum sufficient to enable the Company to repay the amount (if any) owed by it to the Vendor's Group taken into account within the Provisional Intra-Group Debt Amount, and the Vendor shall procure that, immediately after receipt of that sum, but prior to Completion, (i) such sum shall be paid by the Company to the Vendor (as trustee for the relevant members of the Vendor's Group) in repayment of such amount, and (ii) the relevant member of the Vendor's Group shall repay to the Company the amount (if any) owed to the Company taken into account within the Provisional Intra-Group Debt Amount provided that the price adjustments under Clauses 4, 5 and 6 shall be made disregarding such loan and the payments in (i) and (ii) above, and the Vendor shall prepare its notifications under sub-clauses 4(a) and 5(b) disregarding such loan and such payments (and for the avoidance of doubt this sub-clause 6(a) does not affect the Vendor's ability to prepare such notifications taking into account any cash that will be applied to reduce the Final Intra-Group Debt Amount up until immediately before such loan and such payments).

(b) Subject to Clause 4(b), in relation to the Final Intra-Group Debt Amount:

(i) if the Final Intra-Group Debt Amount is greater than the Provisional Intra-Group Debt Amount then the Vendor shall pay an amount equal to the difference, together with an amount equivalent to interest which has accrued on the amount of the difference outstanding from time to time at the Agreed Rate for the period from the Completion Date to the date the relevant difference is repaid, to the Purchaser within ten Business Days of the agreement or determination of such Final Intra-Group Debt Amount;

(ii) if the Final Intra-Group Debt Amount is less than the Provisional Intra-Group Debt Amount then the Purchaser shall pay an amount equal to the difference, together with an amount equivalent to interest which has accrued on the amount of the difference outstanding from time to time at the Agreed Rate for the period from the Completion Date to the date the relevant difference is repaid, to the Vendor within ten Business Days of the agreement or determination of such Final Intra-Group Debt Amount.

(c) Payments to be made under this Clause 6 from the Purchaser to the Vendor or vice versa shall constitute an adjustment to the Initial Cash Consideration.

(d) Within 20 Business Days of Completion, the Vendor shall notify the Purchaser of the calculation of the Final Intra-Group Debt Amount owed by the Company together with reasonably detailed supporting documentation. The Purchaser shall notify the Vendor of any dispute in relation to any such amount within 30 Business Days of the date of the Vendor's notice and shall provide reasonable details of the grounds for disputing such amount and (so far as reasonably practicable) of the amount which the Purchaser believes in good faith to be the correct amount for the Final Intra-Group Debt Amount. The Purchaser shall be deemed to have agreed to the Final Intra-Group Debt Amount if it does not so dispute within 30 Business Days of the date of the Vendor's notice.

(e) If the Purchaser serves notice of a dispute in accordance with sub-clause 6(d), and if the Vendor and the Purchaser are unable to agree the Final Intra-Group Debt Amount within 15 Business Days of the date of the Purchaser's notice referred to in sub-clause 6(d) (or such longer period as they may agree), then the determination of the Final Intra-Group Debt Amount may be referred for determination by any party to the Expert who shall be instructed to notify both the Vendor and the Purchaser of his determination and of the reasons for it within 20 Business Days of such referral. In making his determination the Expert shall act as expert and not arbitrator and his determination shall, in the absence of manifest error, be final and binding and deemed to have been accepted and approved by the Vendor and the Purchaser and shall be deemed to constitute the relevant Final Intra-Group Debt Amount for all purposes of this Agreement. The fees and costs of the Expert incurred under this Clause 6 shall be paid as to one-half by the Vendor and one-half by the Purchaser unless otherwise directed by the Expert (who shall have the authority to make such direction if he deems it equitable).

(f) For the purposes of determining and agreeing the Final Intra-Group Debt Amount the Purchaser shall, and shall procure that the Company shall, give the Vendor and the Expert reasonable access at all reasonable times to all books and records relating to such Final Intra-Group Debt Amount in their respective possession or control and the Vendor shall procure that each member of the Vendor's Group shall give the Purchaser and the Expert reasonable access at all reasonable times to the books and records of each member of the Vendor's Group relating to such Final Intra-Group Debt Amount and each party shall promptly respond to all reasonable enquiries and provide such other information within its control as may reasonably be requested by the other and/or the Expert for that purpose.

(g) In determining the Final Intra-Group Debt Amount, the definitions, principles, policies, procedures and methods and practices of accounting set out in Attachment IV shall be applied.

(h) All payments referred to in this Clause 6 shall be made in immediately available funds to the Vendor's Account or, as the case may be, the Purchaser's Account.

(i) The Vendor undertakes that it will identify to the Purchaser no later than the time of delivery of the Vendor's notice referred to in Clause 6(d) above all items which are properly to be included in the Final Intra-Group Debt Amount.

The Vendor undertakes that immediately prior to Completion the individuals listed in Schedule 1 in the definition of "so far as the Vendor is aware" will be consulted by one or more of the individuals named in the preceding sentence of this paragraph in order to determine whether a notification is required under this sub-clause in relation to a breach of this Clause 8 or any of the Warranties.

Subject to the following sentence, if following Completion, it is discovered that any Intra Group Balance remains after such repayment, whether owing by the Company or by a member of the Vendor's Group, such remaining Intra-Group Balance shall be written off by the Company and the relevant member of the Vendor's Group. Where any such remaining Intra-Group Balances are owed to the Company and, had all such Intra-Group Balances been settled immediately prior to Completion, that settlement would have resulted in an increase in the Initial Cash Consideration pursuant to an adjustment under Clause 4(a)(i) or (ii), but for the fact that such increase was prevented or limited under Clause 4(a) by virtue of it otherwise resulting in an amount over the Debt Free Price being payable, then to the extent only that such increase would have been so prevented or limited, the Company shall not be obliged to write off such remaining Intra-Group Balances.

(h) Following the date of this Agreement and prior to the Completion Date the Vendor shall be permitted to procure that the Company completes the Lease.

(a) From the date hereof until the Completion Date, the Vendor will not, and will procure that the Company will not, agree to any amendment to the terms of the LDPE Technology Licence.

(b) If, between the date hereof until the Completion Date, any new information (and "new information" shall for the purposes of this Clause have the meaning ascribed to it in Clause 2(a)(iii)) comes to the attention of either the Vendor or the Purchaser which relates to the period prior to the date hereof and which is relevant to the interpretation of the LDPE Technology Licence, the Vendor or the Purchaser (as the case may be) shall promptly inform the other and thereafter the Vendor and the Purchaser shall as soon as reasonably practicable and on a shared cost basis jointly instruct Lord Grabiner Q.C. by:

(i) providing him with the new information that has emerged; and

(ii) seeking an opinion confirming that such new information would not change the conclusion in paragraph 16 of his opinion, given on 6 September 2006, that the terms of the LDPE Technology Licence do not permit ExxonMobil either to terminate such licence or to accelerate the payment of royalties under such licence in each case as a result of the proposed sale of the Company to the Purchaser and that such claims, if put forward by ExxonMobil before a court or arbitrator correctly applying English law, would fail.

(c) In the event that Lord Grabiner Q.C. is not available, by reason of death, incapacity or otherwise, to provide this second opinion, the Vendor and the Purchaser shall as soon as reasonably practicable and on a shared cost basis jointly instruct Laurence Rabinowitz Q.C., or in the event of his unavailability, Mark Barnes Q.C., by:

(i) providing him with the instructions previously given to Lord Grabiner Q.C. and a copy of his opinion, together with the new information and a copy of the LDPE Technology Licence; and

(ii) seeking an opinion confirming that, taking into account such new information, he would conclude that the terms of the LDPE Technology Licence do not permit ExxonMobil either to terminate such licence or to accelerate the payment of royalties under such licence in each case as a result of the proposed sale of the Company to the Purchaser and that such claims, if put forward by ExxonMobil before a court or arbitrator correctly applying English law, would fail.

(d) Prior to Completion, the Purchaser may engage in discussions with ExxonMobil in relation to the LDPE Technology Licence, provided that such discussions are limited to appropriate ring-fencing protections to both the Purchaser and ExxonMobil relative to each party's LDPE technology and know-how. If, in the context of such discussions, ExxonMobil indicates that the sale of the Company might have an adverse effect on the ongoing validity of the LDPE Technology Licence or otherwise provides new information, the Purchaser will reasonably promptly notify the Vendor of such fact, and the Vendor will approach ExxonMobil to discuss the matter and will keep the Purchaser informed as to the progress of its discussions.

(e) Prior to Completion, the Purchaser will not seek contractual modifications to the LDPE Technology Licence with ExxonMobil. For the avoidance of doubt, the Purchaser's satisfaction as to its ability to successfully negotiate contractual modifications with ExxonMobil will not be a condition to Completion.

(f) If either the Vendor or the Purchaser fails to comply in any material respect with its obligations under Schedule 2 at Completion then the other may:

(ii) proceed to Completion as far as practicable (without limiting its rights under this Agreement); or

(iii) terminate this Agreement by notice to the other.

(g) The right to terminate under this Clause 10 is without prejudice to Clause 26 and not exclusive of any rights, powers or remedies provided by law, including any right to seek compensation for the other party's breach leading to such termination.

(h) The Purchaser undertakes with the Vendor (for itself and as trustee for each other member of the Vendor's Group) to comply with all notifications and other requirements arising as a result of this Agreement and the transactions contemplated hereunder under any relevant competition, anti-restrictive trade practices or anti-trust laws in circumstances where the Purchaser should reasonably have known, or has been informed by the Vendor, that the Vendor is jointly responsible for such requirement or that the Vendor might incur a liability arising from a failure to comply with such requirements (but not where such requirements are the sole responsibility of the Vendor under such laws).

(i) The Vendor shall give reasonable assistance to the Purchaser in seeking the consent of the Department of Trade and Industry to the change of control of the Company as it relates to the LDPE Grant.

(i) any Senior Employee whose employment with the relevant member of the Vendor's Group has then ceased or who has given (or received) notice terminating such employment;

(ii) any Senior Employee who responds to any bona fide public recruitment advertisement placed by or on behalf of any member of the Purchaser's Group; and

(iii) in response to an unsolicited approach from that Senior Employee,

23. PROVISION RELATING TO RESTRICTIONS

Each undertaking contained in Clauses 21 and 22 shall be construed as a separate undertaking and if one or more of the undertakings is held to be against the public interest or

unlawful or in any way an unreasonable restraint of trade, the remaining undertakings shall continue to bind the Vendor and/or the Purchaser as the case may be.

24. PAYMENTS

(a) Except to the extent otherwise set out in this Agreement, any payment to be made by any party under this Agreement shall be made in full without any set-off, restriction or condition (whether for or on account of any counterclaim or otherwise) and without, and free and clear of, any deduction or withholding whatsoever (save only as required by law).

(b) If any deductions or withholdings are required by law to be made from any sums payable under this Agreement, the party who is obliged to make the payment shall also be obliged to pay to the party to whom payment is to be made (for the purposes of this Clause 24, the "recipient") such sum as will, after such deduction or withholding has been made, leave the recipient with the same amount as it would have been entitled to receive in the absence of any such requirement to make such deduction or withholding except in respect of withholdings and deductions from payments of interest.

PROVIDED that the recipient shall:-

(i) use all reasonable endeavours to obtain and utilise, or as the case may be procure the obtaining and utilisation of, any Tax credit, repayment or other Tax benefit which is available to the recipient or any of its subsidiaries, any holding company of the recipient and any of the other subsidiaries of such holding company from time to time, (together, for the purposes of this Clause 24, the "recipient's group") solely as a result of the matter giving rise to the payment on the same basis as any other Tax credit, repayment or other Tax benefit which is available to the recipient or any other member of the recipient's group; and

(ii) as soon as practicable after the utilisation in whole or in part of any Tax credit, repayment or other Tax benefit which is available to the recipient or any other member of the recipient's group solely as a result of the matter giving rise to the payment, pay to the other party an amount which will leave it, or other such member, (after payment of that amount) in the same after Tax position as it, or other such member, would have been the obligation to make the payment not arisen.

pension scheme and the Pre-Sale Split will be subject to the consent of the trustees of the Huntsman pension scheme;

(h) no party will be required to agree to a Pre-Sale Split if it would give rise to a less favourable tax treatment (or create greater uncertainty about the tax treatment) for that party in connection with the transactions contemplated under this Agreement than if the Pre-Sale Split did not occur;

(i) no party will be required to agree to a Pre-Sale Split if it will lead to Completion taking place at a later date than it would otherwise have taken place (including where it will lead to the non-satisfaction or a delay in the satisfaction of any of the conditions set out in Clause 2) and the agreement and achievement of a Pre-Sale Split will not, for the avoidance of doubt, be a condition to Completion;

(j) the Pre-Sale Split will not result in less consideration being payable by the Purchaser than would otherwise have been the case under this Agreement or in an increase in the liability of the Vendor or any member of the Vendor's Group under any of the Warranties, indemnities or other provisions of this Agreement; and

(k) the Purchaser must provide to the Vendor within 14 days of this Agreement reasonable details of the structure it proposes for the Pre-Sale Split (failing which, there will be no negotiation in relation to the Pre-Sale Split) and the Vendor will be entitled to raise any reasonable objections to such proposal and if, when the parties pursue negotiations relating to the Purchaser's proposal, it becomes apparent that the proposal would involve the Vendor, the Company or any member of the Vendor's Group doing anything which it would not be obliged to do or which is otherwise prevented under paragraphs (c) to (i) above, the Vendor will not be entitled to pursue those negotiations further,

and the provisions of paragraphs (a) to (k) above will apply whether Completion occurs or not, and notwithstanding termination of this Agreement for any reason. If the Pre-Sale Split is agreed, appropriate amendments to the terms of this Agreement and the Tax Covenant shall be made to reflect the provisions of paragraphs (a) to (j) above and the alternative transaction structure. This will include changing references in this Agreement to Shares so that they comprise both shares in the Company and shares in Newco, changing references in this Agreement to the Company to be references to the Company and Newco, changing Clause 8 of this Agreement to permit the restructuring to take place and changing Clause 2 of this Agreement so that any consequences of implementing the Pre-Sale Split will not be treated as a material adverse effect for the purposes of Clause 2(a)(viii) or (ix).

IN WITNESS whereof the parties have entered into this Agreement the day and year first before written.

4. No liability if loss is otherwise compensated for

(A) No liability shall attach to the Vendor by reason of any breach of any of the Warranties or the Tax Covenant to the extent that the same loss has been recovered by the Purchaser under the Tax Covenant or any other Warranty or term of this Agreement or any other document referred to herein and accordingly the Purchaser may only recover once in respect of the same loss.

(B) The Vendor shall not be liable (save that nothing in this sub-paragraph shall prejudice the right of any Further Protected Person under the terms of the Environmental Covenant) for breach of any of the Warranties or under the Tax Covenant or the Environmental Covenant to the extent that the subject of the claim has been or is made good or is otherwise compensated for without cost to the Purchaser or any other member of the Purchaser's Group.

(C) The Purchaser shall use all reasonable endeavours to obtain and utilise, or as the case may be procure the obtaining and utilisation of, any Tax credit, repayment or other Tax benefit which is available to the Purchaser or any other member of the Purchaser's Group solely as a result of the matter giving rise to a liability of the Vendor for any breach of the Warranties or the under the Environmental Covenant and if the Purchaser or any other member of the Purchaser's Group obtains and utilises any such Tax credit, repayment or other Tax benefit, the Purchaser shall, as soon as practicable after the utilisation in whole or in part of any such Tax credit, repayment or other Tax benefit, pay to the Vendor an amount which will leave it (after that payment) in the same after Tax position as it would have been had the obligation of the Vendor to make the payment not arisen. For the purposes of this paragraph, the amount of any Tax credit, repayment or other Tax benefit is to be determined by the auditors of the Purchaser at the shared expense of both parties and is to be certified as such to the Vendor.

5. Recovery from Insurers and other Third Parties

(A) If, in respect of any matter which would give rise to a claim under the Warranties or under the Environmental Covenant, any member of the Purchaser's Group is entitled to claim under any policy of insurance, then no such matter shall be the subject of a claim under the Warranties or under the Environmental Covenant, unless and until the appropriate member of the Purchaser's Group shall have made a claim against its insurers and used all reasonable endeavours to pursue such claim and any such insurance claim shall then reduce by the amount recovered or extinguish any such claims under the Warranties or under the Environmental Covenant.

(B) Where the Purchaser or any member of the Purchaser's Group is at any time entitled to recover from some other person any sum in respect of any matter giving rise to a claim under the Warranties or under the Environmental Covenant (provided that this does not apply to a claim under the ICI Indemnity), the Purchaser shall, and shall procure that the member of the Purchaser's Group concerned shall, subject to the Vendor indemnifying the Purchaser against any liability, cost, damage or expense which may be incurred thereby, take all reasonable steps to enforce such recovery prior to taking action against the Vendor (other than to notify the Vendor of the claim against the Vendor) and, in the event that the Purchaser or any member of the Purchaser's Group shall recover any amount from such other person, the amount of the claim against the Vendor shall be reduced by the amount recovered provided that the Purchaser shall not be required to commence any legal proceedings where either:

(i) the Purchaser or the relevant member of the Purchaser's Group has validly assigned all of its rights in relation to the relevant claim to the Vendor in a manner which entitles the Vendor to the same benefits in respect of such rights as the Purchaser or the relevant member of the Purchaser's Group had; or

(ii) where sub-paragraph (B)(i) does not apply, the Vendor has not notified the relevant party against whom such proceedings are brought that such proceedings are being brought at the instruction of the Vendor.

(C) If the Vendor pays at any time to the Purchaser or any member of the Purchaser's Group an amount pursuant to a claim in respect of the Warranties or under the Environmental Covenant or under any other provision of this Agreement and the Purchaser or relevant member of the Purchaser's Group subsequently recovers from some other person any sum in respect of any matter giving rise to such claim, the Purchaser shall, and shall procure that the relevant member of the Purchaser's Group shall, repay to the Vendor the lesser of (i) the amount paid by the Vendor to the Purchaser or other member of the Purchaser's Group and (ii) the sum (including interest (if any)) recovered from such other person (less, in each case, the costs of recovery of such sum).

(D) For the purposes of paragraph 2 of this Schedule, provided notice of the potential claim is given by the Purchaser to the Vendor within the period specified in that paragraph, there shall be no obligation on the part of the Purchaser to commence proceedings until after the outcome of its claim under its insurance policy or against the third party has been finally dealt with, and the Purchaser's right to maintain its claim against the Purchaser shall not expire by reason of its failure to commence such proceedings. Further, notwithstanding this paragraph 5, the Purchaser may commence Proceedings against the Vendor at any time if by failing to do so it would lose (or risk losing) the right to do so by reason of the operation of any statute of limitation or other time limit.

6. Acts of Purchaser

(A) No claim shall lie against the Vendor under or in relation to the Warranties to the extent that such claim is attributable to:

(i) any act, omission, transaction, or arrangement carried out by the Purchaser or by a member of the Purchaser's Group on or after Completion which the Purchaser or the member of the Purchaser's Group could reasonably have avoided and which it knew or ought reasonably to have appreciated might give rise to the claim; or

(ii) any omission by the Vendor or the Company between the date of this Agreement and Completion that is due to the Purchaser unreasonably withholding its consent to a matter in respect of which consent is sought under Clause 8.

(B) The Vendor shall not be liable for any breach of any Warranty, which would not have arisen but for any reorganisation or change in ownership of any member of the Purchaser's Group or of any assets of any such member after Completion or change in any accounting basis on which any member of the Purchaser's Group values its assets or any accounting basis, method, policy or practice of any member of the Purchaser's Group which is different from that adopted or used in the preparation of the Accounts (provided the Accounts comply with the Warranties in paragraph 9 of Schedule 3).

7. The Accounts

No matter shall be the subject of a claim under the Warranties or under the Environmental Covenant, to the extent that allowance, provision or reserve in respect of such matter shall have been expressly made in the Accounts (other than any such allowance, provision or reserve in respect of Tax).

8. Retrospective legislation

No liability shall arise in respect of any breach of any of the Warranties to the extent that liability for such breach occurs or is increased directly or indirectly as a result of any legislation not in force on or prior to the date of this Agreement or as a result of the withdrawal of any published extra-statutory concession or other agreement or arrangement currently granted by or made with any governmental authority or as a result of any change after the date of this Agreement of any generally accepted interpretation or application of any legislation or in the enforcement policy or practice of the relevant authorities.

9. Purchaser�s knowledge

The rights of the Purchaser to maintain a claim for breach of the Warranties shall not be limited by, nor shall the quantum of damages to which it is entitled thereunder be reduced by any matter of which the Purchaser is, or is alleged to have been, aware (whether actually, or notionally, or vicariously) or which it could have discovered, at or prior to Completion:

(i) except to the extent provided by paragraph 12 of this Schedule 4; and

(C) Shortfall

(i) Subject to paragraph 6(A), if the amount which has been actually transferred (if any) by the Vendor's Scheme to the Purchaser's Scheme on or before the Payment Date in respect of the Transferring Members is less (other than by the application of the final sentence of paragraph 6(B)) than the Transfer Amount plus the Deficit Transfer Amount, then the Vendor shall pay to the Purchaser within 5 Business Days after the Payment Date, so far as possible by way of repayment of the consideration payable for the Shares pursuant to this Agreement, a cash sum in US dollars or, if the Vendor and the Purchaser agree, in pounds sterling (the "Gross Shortfall") calculated according to the formula:

((A-B) + C)

where

A	=	the Transfer Amount plus the Deficit Transfer Amount in pounds sterling;

B	=	the amount in pounds sterling actually transferred on or before the Payment Date multiplied by the Timing Adjustment for the period from and including the date or dates on which such amount was transferred to and excluding the Payment Date;

C	=	the amount representing interest at the Agreed Interest Rate on an amount equal to A - B for the period from and including the Payment Date to and excluding the date on which payment is made under this sub-paragraph,

provided that, if ((A � B) + C) exceeds �18 million then ((A � B) + C) shall be deemed to be equal to �18 million and where, unless the Vendor and the Purchaser agree otherwise, once ((A � B) + C) has been calculated in pounds sterling it is converted to US dollars in accordance with paragraph 6(C)(v).

The amount of the Gross Shortfall shall be determined by the Vendor's Actuary and agreed by the Purchaser's Actuary or, in default of agreement, be determined under paragraph 9.

(ii) (a) If any deduction or withholding is required by law to be made from the payment of the Gross Shortfall, the Vendor shall also be obliged to pay to the Purchaser such sum as will, after such 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 such deduction or withholding.

(b) If any Tax Authority brings into charge to Tax (or into any computation of income, profit or gain for the purposes of any charge to Tax) the payment of the Gross Shortfall, then the Vendor shall pay such additional amount to the Purchaser as shall be required to ensure that the Purchaser is placed in the same after Tax position as if the obligation to make payment of the Gross Shortfall had not arisen.

PROVIDED that the Purchaser shall:-

(aa) use all reasonable endeavours to obtain and utilise, or as the case may be procure the obtaining and utilisation of, any Tax credit, repayment or other Tax benefit which is available to the Purchaser or any other member of the Purchaser's Group solely as a result of the payment of the Gross Shortfall on the same basis as any other Tax credit, repayment or other Tax benefit which is available to the Purchaser or any other such member; and

(bb) as soon as practicable after the utilisation in whole or in part of any Tax credit, repayment or other Tax benefit which is available to the Purchaser or any other member of the Purchaser's Group solely as a result of the payment of the Gross Shortfall, pay to the Vendor by way of further consideration for the Shares an amount in US dollars (such amount to be calculated in accordance with paragraph 6(C)(v)) or, if the Vendor and the Purchaser agree, in pounds sterling equal to the amount of Tax which has been saved by the Purchaser or any other member of the Purchaser's Group in consequence of utilising in whole or in part such Tax credit, repayment or other Tax benefit.

(iii) If, after the Payment Date, the Vendor's Scheme makes any payment in respect of any benefits retained by the Vendor's Scheme in respect of any Transferring Member the Purchaser shall pay forthwith to the Vendor so far as possible by way of further consideration for the Shares a cash sum in US dollars equal to that payment converted to US dollars in accordance with paragraph 6(C)(v) or, if the Vendor and the Purchaser agree, in pounds sterling,

provided that the Vendor shall be required to use its reasonable endeavours to prevent any payment being made by the Vendor's Scheme where such payment is not legally required. If the Purchaser does not pay the amount due under the previous sentence within 2 days of the date of the payment in respect of benefits by the Vendor's Scheme, the Purchaser shall, in addition, pay interest at the Agreed Interest Rate (as well after as before judgment) on the amount due from and including the date on which the payment was made by the Vendor's Scheme to and excluding the date on which payment actually is made by the Purchaser.

(iv) Whenever, after the payment by the Purchaser of any amount due under paragraph 6(C)(iii), the Vendor achieves a reduction in its liability to corporation tax as a result of being able to treat a payment of an amount equal to that amount to the Vendor's Scheme as deductible for corporation tax purposes, the Vendor shall pay to the Purchaser, within 7 days after the Vendor would otherwise have been liable to pay the saved corporation tax, so far as possible by way of repayment of the consideration payable for the Shares pursuant to this Agreement a cash sum in US dollars equal to that corporation tax reduction converted to US dollars in accordance with paragraph 6(C)(v) or, if the Vendor and the Purchaser agree, in pounds sterling.

(v) For the purposes of this paragraph 6(C), where any monetary sum is expressed in a currency other than US dollars, that amount shall be translated into US dollars at the closing rate of exchange on the last Business Day prior to the date of payment under the relevant provision of this paragraph 6(C) as published by Bloomberg, or, where no such rate of exchange is published in respect of that date, at the rate quoted by Reuters as at close of business on that date. For these purposes, what constitutes a "Business Day" will be determined by reference to days on which banks are open for business in London (other than solely for trading and settlement in euros), but not taking into account whether banks are open in New York or The Netherlands.

7. VOLUNTARY FUND

(A) Meaning of "Voluntary Fund"

In this paragraph 7, the expression "Voluntary Fund" means a fund comprising those voluntary contributions, or the investments or moneys representing them and any income derived from them, in respect of which the entitlements of the members who have paid them are not related to earnings (however defined) but are based on the respective parts of such Voluntary Fund which are attributable to them.

(B) Voluntary Fund to be disregarded for calculations

Notwithstanding the preceding provisions of this Schedule, if within the Vendor's Scheme there is a Voluntary Fund, the Voluntary Fund, the benefits payable from it, the contributions payable to it and any transfer payment made from it shall be disregarded for all the preceding provisions of this Schedule.

(C) Transfer of Voluntary Fund

The Vendor shall nevertheless use its reasonable endeavours to procure that the part of the Voluntary Fund attributable to the Transferring Members in accordance with the provisions of the Vendor's Scheme is transferred to the Purchaser's Scheme on the Payment Date.

8. TRANSFER AMOUNT TO PURCHASE BENEFITS FOR TRANSFERRING MEMBERS

Subject to receipt of the Transfer Amount (as reduced in accordance with the final sentence of paragraph 6(B), if applicable) by the Purchaser's Scheme (and, where applicable, the payment of the Gross Shortfall by the Vendor under paragraph 6(C)), the Purchaser shall procure that the Purchaser's Scheme shall provide benefits in respect of the pensionable service (including transfer credits) of each Transferring Member in the Vendor's Scheme before Completion which are identical to the benefits applying in the Vendor's Scheme (as in force on the date of this Agreement) in relation to such service.

9. DISPUTES

(A) Referral to an independent Actuary

(i) Any dispute between the Vendor's Actuary and the Purchaser's Actuary concerning the determination or agreement of the Transfer Amount or of any other matters to be determined or agreed by them for the purposes of this Schedule shall, in the absence of agreement between them, be referred to an independent Actuary.

(ii) The independent Actuary shall be nominated jointly by the Vendor and the Purchaser or, failing such nomination, shall be nominated by the President for the time being of The Institute of Actuaries at the instance of the party first applying to him. If the independent Actuary is unable to agree the terms of his appointment with the Vendor and the Purchase jointly, the terms of his appointment shall be agreed between him and the Vendor.

(B) Independent Actuary to act as expert and direct payment of costs

The independent Actuary so appointed shall act as an expert and not as an arbitrator. His decision shall be final and binding. His costs shall be borne between the Vendor of the one part and the Purchaser of the other part as the independent Actuary may direct.

10. NO ASSISTANCE TO BE GIVEN BY THE PURCHASER

(A) No assistance to be given which would result in an amount larger than the Transfer Amount being payable

(i) The Purchaser undertakes neither to take any action nor to assist, whether directly or indirectly, any person in any manner which would result in the Vendor's Scheme having to pay a larger amount than the Transfer Amount to the Purchaser's Scheme.

100

(ii) The Purchaser agrees that this undertaking extends to the Purchaser and any other company directly or indirectly controlled or connected with the Purchaser.

(B) Purchaser's Scheme trust deed and rules to require Purchaser to approve acceptance of transfer payment

The Purchaser undertakes to the Vendor:

(i) that on and after the Completion Date the trust deed and rules of the Purchaser's Scheme will require that the Purchaser must approve the acceptance of any transfer payment to be made by the Vendor's Scheme to the Purchaser's Scheme pursuant to the terms of the Transfer Agreement; and

(ii) that it will not give such approval to the extent that the total payment proposed to be made to the Purchaser's Scheme by the Vendor's Scheme exceeds an amount equal to the Transfer Amount for any reason including without limitation any statutory or other requirement that transfer values be of a minimum amount.

11. CALCULATION OF LIABILITY

In quantifying any liability, damage, cost, claim or expense which either party may incur or sustain arising out of or in connection with the breach by the other of any of the provisions of this Schedule, the parties agree that the Actuarial Assumptions shall be applied as nearly as may be and in default of agreement as to how they should apply, the disagreement shall be resolved in accordance with paragraph 9.

12. THIRD PARTY RIGHTS

(A) Certain of the provisions of this Schedule confer a benefit on the persons specifically referred to in that provision (each a "Third Party") and, subject to paragraph 12(B), are intended to be enforceable by each Third Party by virtue of the Contracts (Rights of Third Parties) Act 1999.

(B) Notwithstanding paragraph 12(A), such provisions may be rescinded or varied in any way and at any time by the parties to this Agreement without the consent of any Third Party.

6.6 If the auditors certify under sub-clause 6.5 that an amount previously certified should be amended, that amended amount shall be substituted for the purposes of sub-clause 6.4 as the

115

Relevant Amount in respect of the certification in question in place of the amount originally certified, and such adjusting payment (if any) as may be required by virtue of the above-mentioned substitution shall be made as soon as practicable by the Covenantor or (as the case may be) to the Covenantor.

7. RECOVERY FROM OTHER PERSONS

(A) any sum so recovered by the Company in respect of that Tax Liability (including any interest or repayment supplement paid by the Tax Authority or other person on or in respect thereof, but less any Tax payable by the Company in respect of that interest); and

(B) the amount paid by the Covenantor under Clause 2 (COVENANT) in respect of that Tax Liability.

8. CLAIMS PROCEDURE

(A) in a case that involves an actual payment of Tax by the Company, the date falling two Business Days before the last date on which the Company would have had to have paid to the appropriate Tax Authority the Tax that has given rise to the Covenantor's liability under this deed in order to avoid incurring a liability to interest or a charge or penalty in respect of that Tax Liability; or

(B) in any other case, the date falling five Business Days after the date when the Covenantor have been notified by the Company or the Purchaser that the auditors for the time being of the Company have certified, at the request of the Purchaser or the

119

Company, that the Covenantor has a liability for a determinable amount under Clause 2 (COVENANT).

10.2 If any payment required to be made by the Covenantor under this deed is not made by the due date for the making thereof, then, except to the extent that the Covenantor's liability under Clause 2 (COVENANT) compensates the Purchaser for the late payment by virtue of its extending to interest and penalties, that payment shall carry interest from that due date until the date when the payment is actually made at the Agreed Rate on the basis of a 365-day year and actual days elapsed, and to accrue daily (but without compounding).

11. DEDUCTIONS FROM PAYMENTS, ETC.

11.1 All sums payable by the Covenantor to the Purchaser under this deed shall be paid free and clear of all deductions or withholdings whatsoever, save only as may be required by law.

11.2 If any deductions or withholdings are required by law to be made from any of the sums payable as mentioned in sub-clause 11.1, the Covenantor shall be obliged to 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.

11.3 If any sum payable by the Covenantor to the Purchaser under this deed (other than interest under Clause 10 (DUE DATE OF PAYMENT) shall be subject to a Tax liability in the hands of the Purchaser, the Covenantor shall be under the same obligation to make an increased payment in relation to that Tax liability as if the liability were a deduction or withholding required by law.

11.4 If the Purchaser has assigned the whole or part of the benefit of this deed, then sub-clauses 11.2 and 11.3 shall only apply to the extent that the Covenantor would have been obliged to make such payment or payments had no such assignment occurred.

12. SURRENDER OF GROUP RELIEF

12.1 The Purchaser shall procure that the Company shall surrender (to the extent permitted by law) to the Covenantor or to such other member of the Covenantor's Group as the Covenantor may specify all such Group Relief as the Covenantor may at its sole discretion direct in writing in respect of the Straddle Period and any prior accounting period of the Company.

12.2 The Purchaser hereby undertakes that it shall, and shall procure that the Company will, use all reasonable endeavours to procure that full effect is given to the surrenders to be made under

120

sub-clause 12.1 and that such surrenders are allowed in full by HM Revenue & Customs and (without prejudice to the generality of the foregoing) the Purchaser shall procure that the Company shall sign and submit to HM Revenue & Customs all such notices of consent to surrender (including provisional or protective notices of consent in cases where any relevant Tax computation has not yet been agreed) and all such other documents and returns as may be necessary to secure that full effect is given to this Clause 12.

12.3 In consideration of each of the surrenders to be made under sub-clause 12.1, the Covenantor shall pay to the Company or, as the case may be, shall procure that the relevant member of the Covenantor's Group shall pay to the Company a sum equal to the amount of corporation Tax from which the relevant claimant company has been relieved by virtue of that surrender being validly and effectively made; PROVIDED THAT the provisions of this sub-clause shall not have effect if and to the extent that payment in respect of any such surrender has been made on the basis specified in the foregoing provisions of this sub-clause on or before the date of this deed.

12.4 Any sum payable under sub-clause 12.3 shall be paid on the date on which any corporation Tax chargeable on the taxable profits of the relevant claimant company for the accounting period to which the relevant surrender relates becomes due and payable (or would have become due and payable had the Company incurred any liability to corporation Tax in respect of that accounting period).

12.5 In the event that any payment is made in accordance with the foregoing provisions of this Clause 12 in respect of any surrender of Group Relief made under sub-clause 12.1 and corporation Tax falls nevertheless to be charged in respect of the taxable profits that the relevant surrender was intended to relieve from such Tax (whether as a result of HM Revenue & Customs refusing to allow Group Relief or subsequently withdrawing Group Relief in respect of the relevant surrender or for any other reason whatsoever), the Purchaser shall procure that the Company shall forthwith repay to the Covenantor or to the relevant member of the Covenantor's Group either the sum previously paid in respect of the relevant surrender in accordance with the foregoing provisions of this Clause 12 or, as the case may be, such part of that sum as is attributable to the element of the surrender that did not have the effect of relieving from corporation Tax the taxable profits intended to be relieved by virtue of that surrender.

12.6 The Purchaser shall pay to the Covenantor by way of an adjustment to the consideration payable under the Agreement for the Shares an amount equal to the payment required to be made by the Covenantor or other member of the Covenantor's Group pursuant to sub-clause 12.3 on the same date that such payment is made.

12.7 The Covenantor shall pay to the Purchaser by way of an adjustment to the consideration payable under the Agreement for the Shares an amount equal to any payment required to be made by the Company pursuant to sub-clause 12.5 on the same date that such payment is made.

12.8 The Purchaser shall procure that the Company shall claim (to the extent permitted by law) from the Covenantor or from such member of the Covenantor's Group as the Covenantor may

121

specify such Group Relief as the Covenantor may at its sole discretion direct in writing in respect of the Straddle Period and any prior accounting period of the Company provided that nothing in this sub-clause or sub-clause 12.9 shall require the Company to make any payment in consideration for such surrender.

12.9 The Purchaser hereby undertakes that it shall, and shall procure that the Company will, use all reasonable endeavours to procure that full effect is given to the claims to be made under sub-clause 12.8 and that such claims are allowed in full by HM Revenue & Customs and (without prejudice to the generality of the foregoing) the Purchaser shall procure that the Company shall sign and submit to HM Revenue & Customs all such claims and other documents and returns as may be necessary to secure that full effect is given to sub-clause 12.8.

The Purchaser shall not be disentitled from claiming under this Schedule 9 as a result of any reasonable delay in providing such notice or reasonable failure to provide information in such notice, where such delay or failure has not prejudiced the Vendor.

3.19 Subject to paragraph 3.20, the Vendor shall not be liable in respect of a claim under the Part A2 Indemnities in respect of a claim in relation to Pre-1999 North Tees Soil and Groundwater Contamination under an ICI Insolvency Default Payment or any Top-up Payment in relation to such matter only unless such written notice has been given before 1 January, 2031. For the avoidance of doubt, this paragraph 3.19 does not apply to Post-1999 North Tees Soil and Groundwater Contamination, the Benzene Spillage and/or Sealed Structure Contamination or to any claim in relation to Pre-1999 North Tees Soil and Groundwater Contamination save to the extent provided for in this paragraph 3.19.

3.20 The liability of the Vendor in respect of such claim under the Part A2 Indemnities shall absolutely determine (if such claim has not been satisfied, settled, or withdrawn) if, after the relevant Final notice, order or requirement referred to in paragraph 4.1 exists, legal proceedings in respect of such claim shall not have been commenced by the Purchaser against the Vendor within 12 months of the service of notice by the Vendor requiring commencement of proceedings (a "Claim Commencement Notice") and for this purpose proceedings shall not be deemed to have been commenced unless they shall have been properly issued and validly served upon the Vendor.

Miscellaneous

3.21 The Parties agree that notwithstanding any provision in this Schedule 9 to the contrary, in a claim by the Purchaser in respect of Post-1999 North Tees Soil and Groundwater Contamination, the Benzene Spillage and/or Sealed Structure Contamination the definitions of "Criteria" and of "Significant Environmental Impact" shall be deemed to include an express reference to Future Environmental Law as well as Environmental Law and shall be interpreted as if such reference were expressly included in such definitions, provided that the Vendor does

143

not by virtue of this paragraph make any admission in relation to the ICI Indemnity or undertake any obligation to make a Top-up Payment in respect of Pre-1999 Matters.

LIMITATIONS ON LIABILITY APPLYING TO PART A3 INDEMNITIES

3.22 The limitations on liability set out in paragraphs 4, 5 (to the extent provided for therein), 7 and 13 of Schedule 4 (Limitations on liability) of this Agreement inclusive shall apply to any claim made under the Part A3 Indemnities.

3.23 For the avoidance of doubt, the maximum aggregate liability of the Vendor in respect of claims made in relation to Agreed Demolition Liabilities shall not be subject to the cap of US$400,000,000.00 (US$400 million) provided for in paragraph 3.2 or the overall cap provided for in paragraph 1(B) of Schedule 4 (Limitations on Liability) of this Agreement.

3.24 The Vendor shall not be liable for any claim under the Part A3 Indemnities unless the Purchaser shall have given the Vendor written notice containing (so far as reasonably available) specific details of the claim, including the Purchaser's estimate (on a without prejudice basis and so far as it can reasonably be made at the date of the notice) of the amount of such claim. The Purchaser shall not be disentitled from claiming under this Schedule 9 as a result of any reasonable delay in providing such notice or reasonable failure to provide information in such notice, where such delay or failure has not prejudiced the Vendor.

3.25 Subject to paragraph 3.24, the Vendor shall not be liable in respect of a claim under the Part A3 Indemnities in relation to an Agreed Demolition Unit unless such written notice has been given before the expiry of a period of 12 months after the Agreed Demolition Completion Date in relation to such Agreed Demolition Unit.

3.26 The liability of the Vendor in respect of such claim under the Part A3 Indemnities shall absolutely determine (if such claim has not been satisfied, settled, or withdrawn) if, after the relevant Final notice, order or requirement referred to in paragraph 4.1 exists, legal proceedings in respect of such claim shall not have been commenced by the Purchaser against the Vendor within 12 months of the service of notice by the Vendor requiring commencement of proceedings (a "Claim Commencement Notice") and for this purpose proceedings shall not be deemed to have been commenced unless they shall have been properly issued and validly served upon the Vendor.

TRIGGER CONDITIONS

4.1 Subject to paragraphs 4.2 and 4.3 below, the Purchaser shall not be entitled to make a claim under the Part A1 or Part A2 Indemnities unless and to the extent that Environmental Proceedings have been commenced or issued under Future Environmental Law (in relation to Pre-2006 Completion Protected Matters or the Part A2 Indemnities) or Environmental Law (in relation to the Part A1 Indemnities other than Pre-2006 Completion Protected Matters) by a Governmental Authority or any other person in respect of the same subject matter and such Environmental Proceedings would (even if contested) result in a notice, order or requirement which is Final;

144

4.2 Sub-paragraph 4.1 shall be deemed to have been satisfied if:

(a) notice has been given to the Vendor as required under paragraphs 3.7 and 3.18 (if applicable) and 9.1;

(b) Environmental Proceedings would have been commenced or issued, and would (even if contested) have resulted in a notice, order or requirement which is Final, but for a settlement or agreement reached with the relevant Governmental Authority or other person in accordance with paragraphs 7 and 9, to the extent such settlement or agreement results in Environmental Losses no greater than would have been the case were any such Final notice, order or requirement to have been imposed.

4.3 Where the Vendor has assumed conduct under paragraph 9 and sub-paragraph 4.2(b) is satisfied in relation to the relevant matter at any subsequent time, any right of the Purchaser to claim under this Schedule 9 shall not be adversely affected or reduced as a result of any unreasonable delay or failure by the Vendor thereafter in reaching the relevant settlement or agreement, the assessment of reasonableness to take account of the effect of any such delay or failure both on the terms of any settlement or agreement which may be reached and on the Purchaser's claim under this Schedule 9.

4.4 The requirements of paragraph 4.1 are deemed to be satisfied by an Emergency unless the final determination by an expert under paragraph 13 is that the matter which is the subject of the claim is not an Emergency.

POST-2006 COMPLETION CONDUCT

5.1 The Vendor shall not be liable under the Part A1 Indemnities or Part A2 Indemnities in respect of any matter to the extent that such claim would not have arisen but for, results from or is increased by:

(a) the cessation after 2006 Completion of any operations at any of the Properties; or

(b) any new or different mode or form of industrial process outside the current production methods of the business as at 2006 Completion ("Changed Industrial Process") at any Property after 2006 Completion except to the extent that a valid claim under this Schedule 9 could have arisen irrespective of the Changed Industrial Process, had the existence of the relevant matter been known; or

(d) any development, extension, expansion, construction or intensification or any change of use ("Development"), except to the extent that (a) such Development amounts (in aggregate from 2006 Completion) to no more than 20 per cent of the built footprint at any Property after 2006 Completion, such footprint to be deemed to include as at 2006 Completion the area of the LDPE Plant ("Permitted Development") or (b) if the information revealed by the Development had become known through some other means, (not involving any Development) it would have given rise to a valid claim under

145

this Schedule 9 provided that, in relation to any Development which could affect, disturb or reveal Pre-2006 Completion Soil or Groundwater Contamination:

(1) the Purchaser shall give prior written notice to the Vendor;

(2) the Purchaser shall consult in good faith with the Vendor and shall take account of any reasonable requests of the Vendor made in relation to the process of obtaining permission for and carrying out the Development; and

(3) the Protected Person (its employees, contractors, agents, sub-tenants and licensees) shall in relation to such Development act at all times non-negligently and in accordance with the standards of a Reasonable and Prudent Operator; or

(e) any Remedial Action required by any Governmental Authority under or as a condition of any Permit issued by or informal or formal agreement with a Governmental Authority in connection with Development except to the extent that if the information revealed by the Development had become known through some other means, (not involving any Development) it would have given rise to a valid claim under this Schedule 9; or

(f) any Remedial Action required by a Governmental Authority at any Property under or as a condition of any Permit or informal or formal agreement issued by or made with a Governmental Authority in connection with any Development after 2006 Completion at any property other than any Property; or

(h) save in relation to the renewal of the Pie-Crust Leases on substantially the same terms, any voluntary modification, renewal, termination, surrender or variation by a Protected Person (its employees, contractors, agents, sub-tenants and licensees) after 2006 Completion of any lease or other agreement or arrangement under which any Protected Person occupies or uses all or any part of any Property; or

(i) ownership or occupation by any Protected Person (in the case of the Company, after 2006 Completion) of any adjacent or affected property (except for the Properties); or

(j) any direct or indirect interest of any Protected Person (in the case of the Company, not existing at 2006 Completion) in any present or former owner of any adjacent or affected property (except for the Properties); or

(k) the instigation or initiation by any Protected Person of any Environmental Proceedings, actions or claims by a Governmental Authority, without prejudice in all cases (a) to any permitted act or right of a Protected Person under this Schedule 9; (b) to a Protected Person acting as a Reasonable and Prudent Operator balancing the potential Environmental Losses which may be sustained as a result of its conduct

146

against the potential benefits of such Conduct (such balance to be assessed on the hypothetical assumption that any such Environmental Losses would not be recoverable under this Schedule 9 or otherwise);

(l) the deliberate taking by a Protected Person of any action or step which is calculated or designed to give rise to Environmental Proceedings in order to trigger a claim under this Schedule 9; or

(m) any intrusive Investigative Works by a Protected Person (its employees, contractors, sub-tenants and licensees) which:

(1) do not satisfy the requirements of paragraph 11; or

(2) do not fall within (a) and are undertaken otherwise than for the purpose of Development as referred to in paragraph 5.1(d) or, though carried out for that purpose, are not carried out in accordance with paragraph 5.1(d); or

(3) which exceeds the bi-annual monitoring arrangements already adopted by the Company at the Wilton Site;

(n) any admission of liability (in whole or part) or settlement of any claim by any Protected Person other than in accordance with paragraph 9; or

(o) save for any obligation entered into in accordance with paragraph 22.7, any contractual obligation entered into, varied, amended or otherwise modified after 2006 Completion other than pursuant to this Agreement so as to establish or increase the Environmental Losses of any Protected Person.

SPECIFIC EXCLUSIONS

6.1 The Purchaser shall not be entitled to claim for any Environmental Losses under the Part A1 Indemnities or the Part A2 Indemnities to the extent that the relevant claim would not have arisen but for, results from or is increased by matters which relate to:

(a) except in relation to soil or groundwater contamination, the carrying out of or the failure to carry out works after 2006 Completion which are routine or recurring as a result of the normal and lawful operation of the business of the Protected Person in a negligent manner or other than in accordance with the standards of a Reasonable and Prudent Operator, but, for the avoidance of doubt, not including any failure to carry out routine maintenance in relation to a Discovery Window Defect prior to its discovery;

(b) town and country planning (in the United Kingdom) or comparable land use planning or zoning systems in other jurisdictions except to the extent relating to Hazardous Materials or Waste;

147

6.2 In respect of any claim under the Part A1 Indemnities other than in relation to Pre-2006 Completion Protected Matters and except in relation to paragraphs 8.1(b) and 11.1(a), the Vendor shall not be liable to the extent that the relevant claim would not have arisen but for, results from or is increased by Future Environmental Laws, provided that the Vendor shall not be entitled to exclude, avoid or reduce its liability under this Schedule 9 as a result of Future Environmental Laws which are no more onerous than Environmental Laws and references to Environmental Laws shall be interpreted accordingly.

6.3 Any reference to liability under Environmental Laws or Future Environmental Laws (as applicable) shall be deemed to include any contractual obligation by which a Protected Person is responsible for or to contribute to that liability, to the extent such obligation is in force and binding on the relevant Protected Person at or prior to 2006 Completion or as the direct result of the transactions provided for in this Agreement.

MITIGATION

7.1 The Purchaser and any relevant Protected Person shall mitigate any Environmental Losses under this Schedule 9.

7.2 The Purchaser shall not be entitled to claim under the Part A1 Indemnities or the Part A2 Indemnities in respect of Environmental Losses incurred in obtaining professional services in relation to the subject matter, conduct or validity of the claim during the period prior to making that claim in accordance with paragraph 3.7 or 3.18 above.

DISCLOSURE TO GOVERNMENTAL AUTHORITIES

8.1 Subject to paragraph 8.2 and 9 neither the Purchaser nor any member of the Purchaser's Group shall disclose any information in relation to any matter which could reasonably be expected to be the subject of a claim under the Part A1 Indemnities or the Part A2 Indemnities to any Governmental Authority without the prior written consent of the Vendor except following prior written notice to and consultation with the Vendor in relation to sub-paragraphs (b) and (c) below:

(a) in an Emergency where, because of the circumstances it is impracticable to obtain the prior written consent of the Vendor; or

(b) as required by law;

(c) following the final determination by the expert under paragraph 13 (or earlier agreement between the parties) that there is a Significant Environmental Impact;

(d) in relation to Pre-2006 Completion Compliance Issues following the final determination under paragraph 13.1 (or earlier agreement between the parties) that there is a high likelihood that a Governmental Authority would require any Protected Person to carry out Remedial Action (High Likelihood).

8.2 The notice referred to in paragraph 8.1 shall contain specific reasonable details of the matter proposed to be disclosed, the identity of the Governmental Authority and individual officers to

148

whom the disclosure is to be made and the proposed manner and timetable for disclosure (including any documents or presentations or drafts of the same). The Vendor shall be given 30 days (or such lesser period which allows compliance with the relevant law where paragraph 8.1(b) applies) in which to review and comment on the proposals for disclosure and the Purchaser shall have regard to and incorporate the reasonable requests of the Vendor in relation to the proposed disclosure.

8.3 In the event that the Vendor withholds its consent to a disclosure in circumstances where the Purchaser notifies the Vendor in writing that it is of the opinion that there is a Significant Environmental Impact then the provisions of paragraph 13.1 shall apply.

CLAIMS PROCEDURE

9.1 Upon the Purchaser becoming aware of a matter which could reasonably be expected to give rise to a claim for Environmental Losses under the Part A1 Indemnities, the Part A2 Indemnities or the Part A3 Indemnities the Purchaser shall as soon as reasonably practicable thereafter notify the Vendor by written notice. Without limiting the obligation of the Purchaser to comply with this paragraph 9.1, the purpose of such notice shall be to alert the Vendor to the existence of the relevant matter in order that the Vendor may decide to exercise its rights in relation to conduct and such notice shall (if the Purchaser wishes to proceed with a claim under this Schedule 9) be accompanied by or followed by a notice under clause 3.7 or 3.18.

9.2 The Vendor shall have the right to conduct Environmental Proceedings and Remedial Action in respect of any matter which could reasonably be expected to become a claim under the Part A1 Indemnities, unless the Vendor (i) notifies the Purchaser in writing within a reasonable time thereafter, that it declines the right to conduct under this paragraph; or (ii) is in breach of paragraph 9.10 in circumstances which would result in any material Environmental Losses being incurred by the relevant Protected Person which are not covered by a valid claim under this Schedule 9 and/or would materially adversely affect the value of the Property or the goodwill or good name of such Protected Person, in which event the Purchaser shall have conduct. For the avoidance of doubt the provisions of paragraph 9.6 shall not apply to such conduct by the Vendor of Environmental Proceedings or Remedial Action under this paragraph.

9.3 Subject to paragraph 9.10 below, the Vendor shall have the right at any time to assume by written notice to the Purchaser conduct of all or any part of any Environmental Proceedings or the carrying out of any Remedial Action relating to or affecting any claim under the Part A1 Indemnities or the Part A2 Indemnities provided that if the Vendor has assumed any such conduct and the Vendor is in breach of paragraph 9.10 in the circumstances described in paragraph 9.2 above the Purchaser shall be entitled to have conduct.

9.4 The Purchaser shall promptly provide the Vendor with such reports, documents, correspondence, information, assistance and facilities relating to any Environmental Proceedings or Remedial Action or other matter for which written notice has been given under paragraphs 3.7, 3.18 or 9.1 as the Vendor may reasonably require the Purchaser to provide

149

(including if required by the Vendor reasonable access to any Property or so far as practicable adjacent or affected property) except that nothing in this paragraph shall require any waiver of legal privilege or breach of any duty of confidentiality excluding any duty of confidentiality between the Purchaser (or the relevant Protected Person) and any consultant in respect of or relating to Environmental Proceedings or Remedial Action or other matter the subject of written notice under paragraph 9.1. Each party shall use its reasonable endeavours to avoid assuming any duty of confidentiality which would impede the efficient operation of this paragraph 9.

9.5 The Conduct Party shall be entitled to avoid, dispute, deny, defend, resist, appeal, compromise or contest any Environmental Proceedings, or any matter the subject of the relevant written notice (including, without limitation, making counterclaims or other claims against third parties in its own name) and to have the conduct of any Environmental Proceedings, and any related Remedial Action or appeals or other matter the subject of the relevant written notice but no admission of liability shall be made by or on behalf of the Conduct Party and the Environmental Proceedings or other matter the subject of written notice under paragraph 9.1 shall not be compromised, disposed of or settled without, in each case, the consent of the other party (such consent not to be unreasonably withheld or delayed and provided that such consent shall not be withheld where the relevant settlement or agreement satisfies the criteria in paragraph 4.2 (b) (including as to quantum of Environmental Losses) and has been reached in accordance with this paragraph 9).

9.6 The Conduct Party (where the Purchaser is the Conduct Party) shall use its reasonable endeavours to ensure that:

(a) the other party shall be informed promptly of any information which comes to the knowledge of the Conduct Party other than information which the Conduct Party reasonably considers to be immaterial to the Environmental Proceedings or any other matter the subject of the relevant written notice;

(b) the other party shall be allowed a reasonable opportunity to review and to comment upon any material reports documents and correspondence to be prepared and provided by the Conduct Party to the other parties to, or to any Governmental Authority hearing, administering or involved in such Environmental Proceedings or matter the subject of the relevant written notice and the Conduct Party shall have regard to the views of the other party on such reports, documents or correspondence;

(c) the other party shall be provided with advance notice of and be allowed to attend and participate in any material site visit meeting or negotiation involving the Conduct Party (or any subsidiary of the Conduct Party) and any other parties to, or the Governmental Authority hearing, administering or involved in, any Environmental Proceeding or matter the subject of the relevant written notice under paragraph 9.1 and if it so requests and undertakes to pay for the reasonable cost of taking and providing such notes the other party shall be provided promptly with reasonably full and accurate but not verbatim notes of such visit meetings negotiations which it does not attend and participate in;

150

(d) if the other party so requests, copies of all material correspondence and documents passing between the Conduct Party and other parties to the Environmental Proceedings or matter the subject of the relevant written notice under paragraph 9.1 or provided by the Conduct Party to the Governmental Authority hearing, administering or involved in the Environmental Proceedings or matter the subject of the relevant written notice under paragraph 9.1 shall be provided promptly to the other party;

(e) subject to the other Party undertaking to pay the reasonable cost thereof detailed written reports shall be provided to the other Party regarding the status and progress of any Environmental Proceedings or any other matter the subject of the relevant written notice under paragraph 9.1 as frequently and in such form and detail as the other party shall reasonably require;

(f) the other party shall be provided with reasonable notice of any proposal by the Conduct Party or any third party (to the extent the Conduct Party is aware of such proposal) to undertake Remedial Action PROVIDED THAT this obligation shall not apply in case of an Emergency;

(g) any Remedial Action carried out by the Conduct Party or any contractor or subcontractor of the Conduct Party shall be carried out using all reasonable skill and care;

(h) the other party shall be allowed to send such representatives as the other party may reasonably require to attend and inspect the carrying out of Remedial Action whilst they are being carried out PROVIDED THAT such representatives shall not interfere with the proper undertaking of the Remedial Action or the operation of the relevant business or the activities of any third party;

(i) where an environmental expert is to be appointed the Conduct Party shall consult with the other party and have regard to the other Party's views on whom to appoint, the scope of the appointment and the terms and conditions of appointment.

9.7 Each party shall comply with the reasonable requests of the other for arrangements or procedures to maintain confidentiality or legal privilege in relation to any matters arising out of or relating to any Environmental Proceedings, Remedial Action or other matter the subject of written notice under paragraph 9.1.

9.8 The other party shall give the Conduct Party or its agents or contractors access to personnel, premises, chattels, documents and records as the Conduct Party may reasonably request and allow without limitation entry to premises to make such examination and investigations as the Conduct Party may consider necessary, the taking of samples, measurements, photographs and recordings of soil, air, water or substances and combinations of substances at any Property, with the full co-operation of the other party, the interviewing of any person the Conduct Party has reasonable cause to believe to be able to give relevant information and the production of extracts, papers and records in relation to any matter which is or is likely to be the subject of a claim under the Part A1 and Part A2 Indemnities.

9.9 The other party shall in a timely fashion:

151

(a) provide the Conduct Party with such information as it may reasonably require to enable it to assist in the conduct of Environmental Proceedings;

(b) consult in good faith with the Conduct Party in relation to Environmental Proceedings; and

(c) provide the Conduct Party with such material information as comes to the knowledge of the other Party and which relates to the Environmental Proceedings.

9.10 Where the Vendor has conduct of all or any part of Environmental Proceedings pursuant to paragraph 9.2 above, or assumes conduct of all or any part of Environmental Proceedings pursuant to paragraph 9.3 above, the Vendor shall (subject to appropriate arrangements to maintain confidentiality and privilege):

(a) provide reasonably frequent and reasonably detailed reports to the other party regarding the progress of Environmental Proceedings or Remedial Action;

(b) allow the other party a reasonable opportunity to review and comment in advance on proposals for Remedial Action;

(c) develop in consultation with the other party, proposals for Remedial Action, having regard to the Vendor's obligation at sub-paragraph (f) below;

(d) have regard to and incorporate the reasonable requests of the other party in relation to such Environmental Proceedings or Remedial Action (unless any such request of the other party would in excess of the cost of complying with (e) and (f) increase the amount of Purchaser's claim or the cost of the Remedial Action in excess of the cost of complying with (e) and (f) in which case the Purchaser shall be liable to the Vendor for any such increase in relation to such request which is accepted by the Vendor);

(e) carry out Remedial Action in a proper and workmanlike manner (including, in relation to any claims which are not the subject of a claim on the Further Protected Persons Basis under Part B only, complying with each and every term of the leases of any of the Properties to the extent that such terms are applicable) and proceed with the same in a timely manner and with due diligence;

(f) so far as reasonably practicable avoid or minimise interruption or disruption to the business carried on at any of the Properties;

(g) if so requested by the Purchaser (a) carry out any intrusive Investigative Works where and to the extent that the criteria in paragraph 11.1 are satisfied; and (b) make any disclosure where and to the extent that the criteria in paragraph 8 are satisfied. Any right of the Purchaser to claim under this Schedule 9 which would have arisen had the Purchaser retained conduct and carried out such work or made such disclosure shall not be adversely affected or reduced as a result of any unreasonable delay in complying with any such request (the assessment of reasonableness to take account of all relevant matters including the effect of any such delay on the Purchaser's claim under this Schedule 9, or the claim which the Purchaser would have had, but for such

152

delay having regard to when the Purchaser might reasonably have been expected to have carried out such work or made such disclosure had the Purchaser retained conduct).

STANDARD OF WORKS

10.1 The Purchaser shall not be entitled to claim under the Part A1 Indemnities or the Part A2 Indemnities in respect of the cost of carrying out Remedial Action except for the reasonable costs of such Remedial Action which are the minimum necessary:

(a) to comply with the Final notice, order or requirement of a Governmental Authority acting under Environmental Law or (in relation to Pre-2006 Completion Protected Matters or Part A2 Indemnity Matters) Future Environmental Law or a settlement or agreement under paragraph 4.2; or

(b) to address the Emergency (which for the avoidance of doubt excludes anything other than such works as are necessary at the time of the Emergency to (a) remove the direct cause of and (b) control the immediate effects of the Emergency).

INVESTIGATIVE WORKS

11.1 The Purchaser shall not be entitled to claim under the Part A1 Indemnities or the Part A2 Indemnities for any Investigative Works in relation to any Pre-2006 Completion Protected Matters or Pre-2006 Completion Environmental Conditions or Pre-2006 North Tees Soil and Groundwater Contamination, the Benzene Spillage or Sealed Structure Contamination except where and to the extent that such Investigative Works:

(a) are specifically and lawfully ordered or required by the relevant Governmental Authority under law; or

(b) are carried out in accordance with paragraph 7 and 9 in relation to a matter where:

(1) a notice has been served under paragraphs 3.7 or 3.18;

(2) the Vendor has not assumed conduct under paragraph 9;

(3) on the basis of the available information (prior to the relevant Investigative Works) there are reasonable grounds to believe that Significant Environmental Impact may exist.

STATEMENTS

12.1 In the event of any circumstances arising which do or could reasonably be expected to give rise to a claim for Environmental Losses neither the Purchaser, Protected Persons nor the Vendor or any member of the Vendor's Group shall make any public statements (including, for the avoidance of doubt, any statement to any Governmental Authority, unless required by law or in an Emergency) regarding such circumstances without first discussing with the other party and reaching written agreement on the text of any such public statement before it is made,

153

such agreement not to be unreasonably withheld or delayed by either Party and without prejudice to paragraph 8.1.

DISPUTES

13.1 If any dispute arises between the Vendor and the Purchaser as to:

(a) whether or not an Emergency arose; or

(b) whether or not a High Likelihood exists; or

(d) whether a matter is to be deemed to be Substantially Pre-1999 for the purposes of Part C,

the matter shall be referred for final determination in accordance with the Criteria, at the request of either of the Vendor or the Purchaser to an independent environmental consultant having experience relevant to the matter in dispute as agreed between the Vendor and the Purchaser or in default of any such agreement within seven days of such request by the Vendor or the Purchaser, nominated in accordance with the criteria set out below at the request of either the Vendor or the Purchaser by or on behalf of the Chief Executive of the Environmental Auditors Registration Association or, if he or she is unable to make a nomination within 28 days (or 14 days in the case of a dispute as to whether a matter is Substantially Pre-1999 for the purposes of Part C) of the request made to him or her, by the President for the time being of the Chartered Institute of Arbitrators. Such independent environmental consultant shall act as an expert and not as an arbitrator and his fees and expenses shall be borne as he shall direct.

13.2 The criteria referred to and to be applied in the nomination of the independent environmental consultant shall be that he shall not have less than 10 years experience relevant to the matter in issue and he shall be a member of a company or firm which has been established for at least three years preceding the date of the nomination.

13.3 The said environmental consultant shall be offered the appointment within seven business days of the parties reaching agreement on the appointment or upon nomination by the Chief Executive of the Environmental Auditors Registration Association or President of the Chartered Institute of Arbitrators as the case may be, he can only be dismissed by the mutual agreement of the Vendor and the Purchaser. The said environmental consultant shall present his written determination within 28 days (or 14 days in the case of a dispute as to whether a matter is Substantially Pre-1999 for the purposes of Part C) of his appointment or nomination or such longer period as the Vendor and the Purchaser may mutually agree.

13.4 The terms of appointment of the environmental consultant will include a provision that neither the Vendor nor the Purchaser will engage the environmental consultant or any consultancy firm with which he is associated after his nomination in relation to the relevant matter without the written consent of the other party.

154

13.5 The decision of the said environmental consultant in relation to the matters referred to in paragraph 13.1 shall in the absence of manifest error be final and binding on the parties hereto.

PART B: PRE-1999 MATTERS UNDER THE CONTRIBUTION AGREEMENT

14.1 The Purchaser shall only be entitled to claim under the Part A1 Indemnities or Part A2 Indemnities in relation to any Pre-1999 Matters on the basis set out in Part D and Part E and subject to and after the application of the provisions set out in Part C for a claim or claims to be made by the Vendor or any member of the Vendor's Group for the benefit of the Purchaser against ICI under the Contribution Agreement in relation to Pre-1999 Matters on the Further Protected Person Basis.

PART C: CONDUCT OF A CLAIM ON THE FURTHER PROTECTED PERSON BASIS

15.1 The Purchaser shall and shall procure that the Protected Persons shall comply with the provisions of the ICI Indemnity in relation to any matters which are or could become the subject of a claim on the Further Protected Person Basis, subject to the provisions of this Part C.

15.2 Upon the Purchaser becoming aware of a matter which the Purchaser bona fide believes could give rise to a claim on the Further Protected Person Basis (irrespective of the strength or merits of the potential claim) the Purchaser shall as soon as reasonably practicable thereafter notify the Vendor by written notice. The purpose of such notice shall be to alert the Vendor to the existence of the relevant matter and the possibility of a claim being made on the Further Protected Person Basis.

15.3 The parties agree that the relevant claim in relation to a matter notified under paragraph 15.2 shall be brought on the Further Protected Person Basis if:

(a) the parties agree that the subject matter of the relevant claim is Substantially Pre-1999; or

(b) in default of agreement it is determined under the Expert Procedure in Part A that on the basis of the available evidence (irrespective of the strength or merits of the potential claim) such matter reasonably appears to be Substantially Pre-1999:

For the purposes of this paragraph 15.3, a matter shall be deemed to reasonably appear to be Substantially Pre-1999 if on the basis of the available information as at as the date of the relevant determination under the Expert Procedure in Part A it is reasonably likely that such matter comprises or relates substantially to Pre-1999 Matters. For the avoidance of doubt, any agreement or determination under this paragraph 15.3 that a matter shall be deemed to be Substantially Pre-1999 shall be binding on the parties for the purposes of determining whether or not a claim shall be brought on the Further Protected Person Basis under this Part C but shall not preclude a claim being brought by the Purchaser under the Part A1 Indemnities or Part A2 Indemnities in the circumstances provided for in paragraph 15.8 below.

155

15.4 Where it is determined in accordance with this Part C that a claim is to be made on the Further Protected Person Basis, the Vendor shall and shall procure that the relevant member of the Vendor's Group shall pursue such claim as expeditiously and diligently as it is reasonably able subject to the Purchaser bearing the Purchaser's costs of so doing and subject to the Purchaser's compliance with its obligations under this Part C.

15.5 The Vendor shall and shall procure that the relevant member of the Vendor's Group shall comply with all requests of the Purchaser in relation to the conduct of such claim on the Further Protected Person Basis:

PART E: APPLICATION OF PART A1 INDEMNITIES OR PART A2 INDEMNITIES IN RELATION TO PRE-1999 MATTERS

17. This Part E relates to circumstances in which a claim on the Further Protected Person Basis is not capable of being made, reduced or avoided as a result of:

(a) the arrangements set out in Part C not validly and effectively giving the relevant member of the Vendor's Group the right to claim in respect of Environmental Losses on behalf of the relevant member of the Purchaser's Group, provided that this sub-paragraph (a) shall not apply:-

(i) where and to the extent there is no valid and effective right to claim as a result of any change in circumstances or matters arising after 2006 Completion where such circumstances or matters arising are within the control of the Purchaser's or any member of the Purchaser's Group (subject to sub-paragraph (e)); and/or

(ii) where and to the extent that the relevant Environmental Losses would not have been recoverable irrespective of the arrangements set out in Part C, unless and to the extent sub-paragraph (c), (d), (e) or (f) applies;

(b) the Vendor or any member of the Vendor's Group (including its employees, contractors, agents, sub-tenants or licensees) failing to comply with Part C;

165

(c) any act or omission of the Vendor or any member of the Vendor's Group (including its employees, contractors, agents, sub-tenants or licensees) before or after 2006 Completion (not being an act or omission which is provided for in Part C);

(d) any act or omission of the Company before 2006 Completion;

(e) the benefit granted to the Vendor in respect of a Further Protected Person under paragraph 16.2 of Schedule 14 of the Contribution Agreement ceasing to apply as the result of a share transaction within the Purchaser's Group satisfying all of the following conditions:

(i) the Company remaining a fully and directly owned subsidiary of the Purchaser following such transaction;

(ii) both the Purchaser and the Company remaining wholly owned subsidiaries of a member of the Purchaser's Group following such transaction; and

(iii) no subsequent transaction (connected with the first transaction) causes the Company or the Purchaser to cease to be wholly owned subsidiaries of a member of the Purchaser's Group;

(f) in the event of ICI Insolvency.

17.2 If and to the extent that a Halo Default or ICI Insolvency has arisen and the relevant Environmental Losses would have been recoverable under the Contribution Agreement but for such Halo Default or ICI Insolvency, then to that extent the exclusion of claims under Part A1 Indemnities or the Part A2 Indemnities in respect of Pre-1999 Matters in paragraph 14.1 shall be deemed to not apply and the Purchaser shall be entitled to claim under the Part A1 Indemnities or Part A2 Indemnities as applicable.

17.3 Where any claim is made by the relevant member of the Vendor's Group on the Further Protected Person basis and is subsequently brought under the Part A1 Indemnities or Part A2 Indemnities as applicable, the conduct provisions set out at paragraphs 7 and 9 shall be applied in a reasonable manner taking account of information available and actions taken in the course of the claim made on the Further Protected Person Basis.

PART F: POST-2006 COMPLETION COUNTER INDEMNITY

18.1 The Purchaser shall indemnify and hold the Vendor and the Vendor's Guarantor for themselves and any member of the Vendor's Group harmless on an after Tax basis ("Post-2006 Completion Counter Indemnity") from and against any liability of any member of the Vendor's Group to ICI in relation to Post-2006 Completion Environmental Conditions under paragraph 14 (Post-Closing Counter Indemnity) of Part A of Schedule 14 of the Contribution Agreement.

18.2 The Purchaser acknowledges that conduct in relation to matters giving rise to a claim by ICI against any member of the Vendor's Group under paragraph 14 (Post-Closing Counter Indemnity) of the Contribution Agreement shall be governed by Part E of Schedule 14 of the

166

Contribution Agreement. The Purchaser shall provide all necessary information, access, facilities and assistance after 2006 Completion to enable the relevant member of the Vendor's Group to comply with its obligations in relation to conduct under Part E of Schedule 14 of the Contribution Agreement.

PART G: AGREED DEMOLITION AND THE AGREED DEMOLITION PROCEDURES

19.1 The Purchaser shall be entitled in its sole discretion to decide whether or not to decommission and/or demolish any or all of the Agreed Demolition Units. If the Purchaser so decides in relation to one or more of the Agreed Demolition Units then the provisions of this Part G shall apply.

19.2 If the Purchaser decides to decommission and/or demolish an Agreed Demolition Unit, the Purchaser shall give prior written notice to the Vendor. The Purchaser will consult in good faith with the Vendor in relation to the proposed work plan for the proposed decommissioning and demolition in advance of commencement and shall take reasonable account of comments provided by the Vendor. The Purchaser shall ensure that the Vendor is provided with such information as it reasonably requires in order for such consultation to take place.

19.3 The Vendor shall be provided with a copy of the agreed demolition work plan determined in accordance with paragraph 19.2 and shall be informed of and consulted with in relation to any proposed changes.

19.4 The Vendor shall be provided with advance notice of commencement of decommissioning and/or demolition and shall be provided with reasonable opportunities to attend and inspect whilst work is being carried out and shall be involved to a reasonable extent in the supervision of the work. The Vendor shall be kept reasonably informed as to the progress of the work and of any matters relevant to compliance with the following provisions of this Part G.

19.5 The demolition and/or decommissioning in relation to an Agreed Demolition Unit shall be carried out in accordance with the Agreed Demolition Work Plan and shall be carried out reasonably and without negligence, having regard to the need to minimise any Agreed Demolition Liabilities.

19.6 Subject to paragraphs 19.7 and 19.8 below, but without prejudice to paragraph 19.5 above, the Agreed Demolition shall not extend beyond any concrete slab or to other surface or sub-surface structures which do contain or are reasonably likely to contain any Hazardous Materials or Waste.

19.7 Where the Agreed Demolition Unit includes surface or sub-surface structures which contain or are reasonably likely to contain Hazardous Materials or Waste (but not, for the avoidance of doubt, any above ground structures) then the Purchaser shall not remove such structure as part of the Agreed Demolition unless taking into account any available information and the need to minimize Agreed Demolition Liabilities the risk presented by such structure is sufficient to justify intrusive investigation and the removal of such structure. Subject to paragraph 19.8, intrusive investigations shall not be carried out in relation to such structure.

167

19.8 If the removal of a structure reasonably appears to the Purchaser to be justified on the basis set out in paragraph 19.7 above, the Purchaser shall consult with the Vendor and the Vendor shall have the right to direct that such structure is not removed and instead is purged, sealed or otherwise so far as reasonably practicable (having regard to the need to minimize Agreed Demolition Liabilities) is made safe without it being removed. The Part A2 Indemnities shall apply to any such structure which is not removed pursuant to a direction under this paragraph as and to the extent provided for therein (for the avoidance of doubt, the limitations at paragraphs 5.1(a), 5.1(c) and 6.1(b) which are applicable to the Part A2 Indemnities will only apply in the context of Sealed Structure Contamination to such structures which are the subject matter of the direction of the Vendor under this paragraph 19.8, once such direction has been given and Sealed Structure Contamination shall not, at any time, be subject to Parts B, C, D and E of this Schedule 9). However nothing in this paragraph 19.8 shall prejudice the right and ability of the Purchaser to remove such structures if required by law (including any Permit or the terms of any applicable lease) to do so, although, where the Purchaser is required by law to remove such structures then he shall as far as reasonably practicable consult with the Vendor and if so requested by the Vendor the relevant Governmental Authority in respect of the work being carried and shall have regard to the reasonable views of the Vendor and the Governmental Authority. Where the Purchaser, having regard at all times to its obligations under this paragraph 19.8, is required to remove such structure by law (including any Permit or the terms of any applicable lease) at the time of or prior to the physical act of decommissioning or demolishing an Agreed Demolition Unit under the Agreed Demolition Work Plan then paragraph 3.16 of this Schedule 9 shall cease to apply to any claim relating to the removal of such structure.

19.9 Where the Purchaser carries out any Remedial Action in connection with the demolition and/or decommissioning at an Agreed Demolition Unit, the Part A1 Indemnities and Part A2 Indemnities shall not apply to such Remedial Action and the Purchaser shall carry out works in relation to such Remedial Action as are the minimum necessary:

(a) to comply with the Final notice, order or requirement of a Governmental Authority acting under Future Environmental Law, a Permit (including, for the avoidance of doubt, any requirements under any Permit on the cessation of operations and the surrender of such Permit if the relevant Governmental Authority so requires) or a settlement or agreement under paragraph 4.2 (mutatis mutandis); or

19.10 The costs of demolition and/or decommissioning shall be borne by the Purchaser (including the removal of asbestos and any other environmental or health and safety matters except as provided for in paragraph 19.11 below).

19.11 The Part A3 Indemnities shall apply in relation to an Agreed Demolition Unit where and to the extent:-

(a) notice is provided by the Purchaser to the Vendor on or before the first anniversary of the Agreed Demolition Completion Date; and

168

(b) a liability arises in relation to:

(i) any soil and groundwater contamination (but not including any Sealed Structure Contamination); and/or

(ii) any Environmental Losses in relation to any structure or item of plant or equipment (including any liquids or other materials contained therein) (disregarding its size, age or complexity or the costs associated with its decommissioning or demolition) where such structure or item of plant or equipment (including any liquids or other materials contained therein) would not usually be encountered in the context of decommissioning and/or demolishing a petrochemicals unit,

in each case, existing at the Agreed Demolition Unit prior to 2006 Completion as the direct result of carrying on the demolition and decommissioning in accordance with this Part G.

19.12 For the avoidance of doubt, where the Purchaser carries out any decommissioning and/or demolition not part of the Agreed Demolition and such decommissioning and/or demolition results in Environmental Losses, the Purchaser shall not by virtue of the Part G be prevented from making a claim under the Part A1 Indemnities or Part A2 Indemnities in respect of such Environmental Losses where the Environmental Losses did not occur as a direct result of the decommissioning and/or demolition.

PART H: MISCELLANEOUS

PAYMENT

20.1 Any sums for which either party is liable under this Schedule 9 shall be due and payable 30 days from the day following service of a proper invoice in accordance with this Agreement.

21.3 It is a condition of any claim by a 2006 Further Protected Person that each 2006 Further Protected Person shall comply with and in all respects be bound by this Schedule 9.

21.4 For the avoidance of doubt, Part I shall not extend or increase the Vendor's liabilities under the Part A1, A2 and A3 Indemnities of this Schedule 9 and any claims brought by a 2006 Further Protected Person shall be limited accordingly.

PART J: DISCOVERY WINDOW

Rebuttable presumptions in relation to soil and groundwater contamination

22.1 Where soil or groundwater contamination is discovered and notified to the Vendor in accordance with paragraph 22.10 prior to the expiry of the Discovery Window, there shall be a rebuttable presumption in favour of the Purchaser and against the Vendor that such soil or groundwater is as applicable Pre-2006 Completion Soil or Groundwater Contamination (as opposed to Post-2006 Soil or Groundwater Contamination) or Pre-2006 North Tees Soil or Groundwater Contamination (as opposed to Post-2006 Soil or Groundwater Contamination). Such rebuttable presumption shall cease to apply if the Vendor is able to prove on the balance of probabilities that such soil or groundwater contamination is Post-2006 North Tees Soil or Groundwater Contamination.

22.2 Where soil or groundwater contamination is discovered and notified to the Vendor in accordance with paragraph 22.10 after the expiry of the Discovery Window, it shall be for the Purchaser to prove on the balance of probabilities that such soil or groundwater contamination is Pre-2006 Completion Soil or Groundwater Contamination or Pre-2006 North Tees Soil or Groundwater Contamination (as opposed to applicable Pre-2006 Completion Soil or Groundwater Contamination or Pre-2006 North Tees Soil or Groundwater Contamination).

170

Rebuttable presumptions in relation to Relevant Defects

22.3 Where any Relevant Defect in a pipe, drain, sump, interceptor or other item of plant or equipment designed to contain liquid or other materials at the relevant Property is discovered by the relevant Protected Person (its employees, contractors, agents, sub-tenants or licensees) and notified to the Vendor during the Discovery Window in accordance with paragraph 22.10 there shall be a rebuttable presumption in favour of the Purchaser and against the Vendor that such fracture, crack, or leak first arose prior to 2006 Completion.

22.4 Where any Relevant Defect in a pipe, drain, sump, interceptor or other item of plant or equipment designed to contain liquid or other materials at the relevant Property is discovered by the relevant Protected Person (its employees, contractors, agents, sub-tenants or licensees) after the Discovery Window it shall be for the Purchaser to prove on the balance of probabilities that such Relevant Defect first arose on or prior 2006 Completion.

22.5 The Purchaser shall procure that the relevant Protected Person carries out any repair, replacement or other corrective action in relation to a pipe, drain or other item of plant or equipment promptly following the discovery of a Discovery Window Defect. Following completion of such work (or the failure to complete such work promptly), the Discovery Window Period shall be deemed to have ceased in relation to that section or part of the pipe, drain or other item of plant or equipment that was subject to the work and there shall be an irrebuttable presumption that any subsequently discovered Relevant Defect in relation to such pipe, drain or other item of plant or equipment shall have arisen after the date of such repair, replacement or other corrective action.

Procedure in relation to Discovery Window

22.6 The Vendor and the Purchaser agree that it is in their respective best interests to ensure that they have equal access to an authoritative and up to date record of matters potentially relevant to whether matters have arisen before or after 2006 Completion as provided for in paragraphs 22.1 to 22.5 above (the "Shared Record") including without limitation:

(a) soil and groundwater monitoring data;

(b) records of spills and leaks;

such information being referred to below as Shared Record Data.

Failing such agreement the Shared Record Consultancy and Shared Record

171

Consultant shall be determined by the Chief Executive of the Environmental Auditors Registered Association and shall not be a firm which has or an individual who has performed any substantial work for the Vendor or the Purchaser or their respective Affiliates during the 5 year period preceding their appointment. Should it become reasonably necessary at any future time to replace the SRC the above procedure shall be applied mutatis mutandis.

22.8 The terms and conditions under which the SRC will act shall be determined by the Vendor and Purchaser acting reasonably and the fees, cost and expenses of the SRC shall be borne equally by the Vendor and the Purchaser. The duration of such appointment shall be five years from the date of 2006 Completion unless the parties agree in writing to extend such period.

(a) any proposal to carry out any assessment or investigation of soil or groundwater;

(b) integrity issues relating to containment of liquid or other materials;

(c) any known or suspected leaks or spills excluding minor leakages or spillages which could not be expected to have an impact below 0.3m of the soil sub-surface;

1. Conduct of business between signing and Completion

(A) The Vendor shall notify the Purchaser as soon as reasonably practicable upon becoming aware of any matter which is more than likely to require either:

(i) a variation to a Fixed Price Contract; or

(ii) the provision of goods or services by third parties (being persons other than members of the Vendor's Group) in respect of the LDPE Project otherwise than pursuant to Fixed Price Contracts to the extent such is consistent with the Project Financial Plan both as regards the stage which the LDPE Project has then reached and the budget for the goods or services in question;

involving (or likely to involve) expenditure in excess of �100,000.

(B) The Vendor shall procure that:

(i) no variation/change order is made to any Fixed Price Contract prior to Completion which will lead to additional expenditure by the Company of more than �100,000 in any individual case; and

(ii) no commitment is entered into by the Company for the provision of goods or services by third parties (being persons other than members of the Vendor's Group) in respect of the LDPE Project involving expenditure by the Company of more than �100,000 in any individual case, except so far as is consistent with the Project Financial Plan both as regards the stage which the LDPE Project has then reached and the budget for the goods or services in question;

except (in each case) with the prior written consent of the Purchaser (such consent not to be unreasonably withheld or delayed and in any event, in relation to a Fixed Price Contract, the Purchaser shall give its decision within 10 Business Days).

(C) For the purposes of determining whether or not anticipated expenditure in a currency other than sterling will exceed the sterling thresholds set out in paragraphs (A) and (B) above, the amount of the anticipated expenditure will be converted to sterling at the spot exchange rate applying at that time.

(D) Any expenditure incurred by the Vendor in breach of paragraph 1(B) shall be excluded from Actual Expenditure for the purposes of paragraph 3(A). Any additional expenditure which is required to achieve Project Completion as a result of the Purchaser unreasonably withholding or delaying its consent where required under paragraph 1(B) shall be deducted from Forecast Expenditure for the purposes of paragraph 3(A).

2. Exchange Rates for determining Actual Expenditure and Forecast Expenditure

(A) In order to determine the amount of Forecast Expenditure, the following exchange rates (the "Budgeted Exchange Rates") will be used to translate amounts of expenditure paid or to be paid in currencies other than US dollars into US dollars:

178

�1 : �1.49725;

�1 : $1.7967; and

�1 : $1.2.

(B) In order to determine the amount of Actual Expenditure:

(i) amounts of Actual Expenditure paid in currencies other than US dollars on or before 30 September 2006 will be translated into US dollars using the Budgeted Exchange Rates; and

(ii) amounts of Actual Expenditure paid in currencies other than US dollars in any calendar month after 30 September 2006 will be translated into US dollars using the Vendor's booking rates, being the closing rate of exchange on the third Business Day prior to the end of the month preceding the month in which such amounts are paid as published by Bloomberg, or, where no such rate of exchange is published in respect of that date, at the rate quoted by Reuters as at close of business in the UK on that date. For these purposes, what constitutes a "Business Day" will be determined by reference to days on which banks are open for business in London (other than solely for trading and settlement in euros), but not in New York or The Netherlands.

3. Actual Expenditure and Forecast Expenditure

(A) If:

(i) the Actual Expenditure is greater than $208,000,000, then the Purchaser shall pay to the Vendor an amount equal to the difference:

(a) plus the amount deducted from the Initial Cash Consideration pursuant to Clause 4(a)(iv)(A) (if any); or

(b) less the amount paid by the Purchaser to the Vendor pursuant to Clause 4(a)(iv)(B) (if any);

(ii) the Actual Expenditure is less than the $208,000,000, then the Vendor shall pay to the Purchaser an amount equal to the difference:

(a) less the amount deducted from the Initial Cash Consideration pursuant to Clause 4(a)(iv)(A) (if any); or

(b) plus the amount paid by the Purchaser to the Vendor pursuant to Clause 4(a)(iv)(B) (if any);

(iii) the Forecast Expenditure is greater than $360,000,000, then the Vendor shall pay to the Purchaser an amount equal to the difference, less the amount deducted from the Initial Cash Consideration pursuant to Clause 4(a)(v) (if any); and

179

(iv) the Forecast Expenditure is less than $360,000,000, then the Purchaser shall pay to the Vendor an amount equal to the amount deducted from the Initial Cash Consideration pursuant to Clause 4(a)(v) (if any),

provided that the above payments shall be netted-off against each other and, within five Business Days of the final agreement or determination of the Actual Expenditure and the Forecast Expenditure, the Vendor shall be obliged to pay the Purchaser the net balance or the Purchaser shall be obliged to pay the Vendor the net balance, as the case may be, together with an amount equal to interest on the net balance at the Agreed Rate (accrued daily) for the period from the Completion Date to the date of payment. Any payment under this sub-paragraph shall constitute an adjustment to the Initial Cash Consideration.

(B) The Vendor and the Purchaser shall use reasonable endeavours to agree in good faith the Forecast Expenditure prior to Completion. Where Forecast Expenditure has been so agreed prior to Completion, the following provisions of this paragraph 3 shall apply only in relation to Actual Expenditure.

(C) Within 30 Business Days of Completion, the Vendor shall notify the Purchaser of its calculation of Actual Expenditure and Forecast Expenditure, together with reasonably detailed supporting figures. The Purchaser shall notify the Vendor of any dispute in relation to any such amounts within 30 Business Days of the date of the Vendor's notice and shall provide reasonable details of the grounds for disputing such amounts and (so far as reasonably practicable) of the amounts which the Purchaser believes in good faith to be the correct amounts for such Actual Expenditure and Forecast Expenditure. The Purchaser shall be deemed to have agreed to the Actual Expenditure or Forecast Expenditure (as the case may be) to the extent it does not so dispute within 30 Business Days of the date of the Vendor's notice.

(D) If the Vendor and the Purchaser are unable to agree the Actual Expenditure or Forecast Expenditure within 30 Business Days of the date of the Vendor's notice referred to in paragraph (C) above, then the determination of Actual Expenditure and/or Forecast Expenditure (as the case may be) shall be referred for determination to the Project Expert who shall be instructed to notify both the Vendor and the Purchaser of his determination and of the reasons for it within 20 Business Days of such referral, and such instructions shall be in the form of the pro forma instruction letter at Annex 2 to this Schedule. In making his determination the Project Expert shall act as expert and not arbitrator and his determination shall, in the absence of manifest error, be final and binding and deemed to have been accepted and approved by the Vendor and the Purchaser and shall be deemed to constitute the Actual Expenditure and/or Forecast Expenditure (as the case may be) for all purposes of this Agreement. The fees and costs of the Project Expert incurred under this paragraph (D) shall be paid as to one-half by the Vendor and one-half by the Purchaser unless otherwise directed by the Project Expert (who shall have the authority to make such direction if he deems it equitable).

(E) For the purposes of determining and agreeing the Actual Expenditure or Forecast Expenditure the Purchaser shall, and shall procure that the Company shall, give the Vendor and the Project Expert reasonable access at all reasonable times to all books and records relating to such Actual Expenditure and/or Forecast Expenditure in their respective possession or control.

180

(F) In determining the Actual Expenditure and/or Forecast Expenditure the definitions, principles, policies, procedures and methods and practices of accounting set out in Attachment IV shall be applied. In relation to the Forecast Expenditure, the Project Expert shall change items in the Forecast Expenditure only to the extent that they arise from the LDPE Forecasting Tool not being applied properly.

ATTACHMENT IV
(Completion Statement)

Completion Statement in respect of Working Capital, Final Cash Amount, Final Third Party Debt Amount and the Final Intra-Group Debt Amount

Preparation of Completion Statement

1. The Completion Statement shall be prepared and agreed in accordance with the provisions of Clauses 5 and 6 and this Attachment IV.

2. Subject only to paragraphs 3, 4, 5, 6 and 7 of this Attachment, the Completion Statement shall:

(A) be extracted from the books and records of the Company;

(B) reflect actual values at Completion (including by reference to the stock take referred to in paragraph 5 below);

(C) exclude all Tax liabilities and deferred taxes other than VAT, payroll taxes, construction industry tax, climate change levy or amounts in respect thereof and all Tax assets or rights to repayments of Tax other than such Tax assets or rights to repayments of Tax relating to VAT, payroll taxes, construction industry tax, climate change levy or amounts in respect thereof;

(D) include a statement of the Completion Working Capital comprising the following line items in the Accounts:

(i) Stocks (including engineering spares) net of provision for stock losses and obsolescence in respect of engineering spares; plus

(ii) Debtors (and, for the avoidance of doubt, there will be no reserve for doubtful or bad debts) including prepayments and other debtors; less

(iii) Creditors due within one year, including accruals and any other short term liabilities,

but excluding any amounts comprised in the following:

(iv) the Final Intra-Group Debt Amount or the Intra-Group Balances;

(v) the Final Cash Amount;

(vi) any payables or accruals in respect of the LDPE Project;

(vii) interest receivable and payable;

(viii) dividends payable and receivable; or

188

(ix) US GAAP adjustments;

(E) include statements of the Final Cash Amount, the Final Third Party Debt Amount and the Final Intra-Group Debt Amount;

(F) subject to sub-paragraphs (B), (C), (D) and (E) and paragraphs 3 to 7, be prepared on the same basis and in accordance with the same principles, policies, procedures, methods and practices of accounting as were applied for the purposes of the Accounts on the basis that the exercise of judgment and discretion in the application of principles, policies, procedures, methods and practices of accounting will be consistent with such exercise as applied in relation to the Accounts and, for the avoidance of doubt, this sub-paragraph (F) shall not prevent changes in factual circumstances (including, but not limited to, the Company's withdrawal from the securitisation program relating to accounts receivable operated by the Vendor's Group) that have taken place between the Accounts Date and Completion from being taken into account in the preparation of the Completion Statement; and

(G) subject to sub-paragraphs (B), (C), (D), (E) and (F) and paragraphs 3 to 7, be prepared in accordance with principles, policies, procedures, methods and practices of accounting generally accepted in the United Kingdom.

Sub-paragraphs (F) and (G) are intended to be applied as a hierarchy, with sub-paragraph (F) being applied first and with sub-paragraph (G) being applied only where ambiguity remains following application of sub-paragraph (F).

3. The Completion Statement shall be prepared on the basis that the Completion Statement relates to the Company as a going concern and excludes any effects of the change of control and ownership of the Company contemplated by this Agreement or any other effect of this Agreement.

4. All balances relevant for the calculation of the Final Intra-Group Debt Amount in the Completion Statement shall be reconciled to the extent practicable between the records of the payer and those of the payee; in the event of any discrepancy, the records of the payee, shall, unless otherwise agreed between the Purchaser and the Vendor, prevail.

5. For the purposes of the Completion Statement, the quantities used for the valuation of Stocks (including engineering spares) shall be based on a physical stock-take conducted on (or as soon as practicable after) the Completion Date, which both the Vendor and the Purchaser (or its accountants) will attend.

6. In the preparation of the Completion Statement, where any monetary sum to be taken into account in calculating the Final Cash Amount, the Final Intra-Group Debt Amount, the Final Third Party Debt Amount or the Completion Working Capital is expressed in a currency other than US dollars, that amount shall be translated into US dollars at the closing rate of exchange on the third Business Day preceding the Completion Date as published by Bloomberg, or, where no such rate of exchange is published in respect of that date, at the rate quoted by Reuters as at close of business in the UK on that date. For these purposes, what constitutes a "Business Day" will be determined by reference to days on which banks are open for

189

business in London (other than solely for trading and settlement in euros), but not in New York or The Netherlands.

7. The Completion Statement shall reflect events which occur and information which becomes available after Completion to the extent that to do so is required by UK GAAP.
