24. CONTRACTS

24.1 Subject to Clause 24.2.3, after the Option Completion Date, the Buyer shall:

24.1.1 perform all the Seller’s obligations to be performed from the Option Completion Date under each Contract (or, in the case of the Enforcement Option only, each Core Contract) (other than payment of the liabilities and settlement of the claims referred to in Clause 23.1) in accordance with the terms of each Contract (or, in the case of the Enforcement Option only, each Core Contract); and

24.1.2 indemnify, and keep indemnified, the Seller on demand against each loss, liability and/or cost which the Seller incurs as a result of the Buyer’s performance, or non-performance, of the Seller’s obligations under each Contract (or, in the case of the Enforcement Option only, each Core Contract) (as referred to in Clause 24.1.1) to the extent that the loss, liability and/or cost is attributable to the Buyer’s act or omission from the Option Completion Date (including each loss, liability and/or cost incurred as a result of defending or settling a claim alleging such liability).

25. EMPLOYEES

25.1 The Buyer and the Seller declare that they each consider the sale and purchase of the Business and the Station Assets under this Agreement shall constitute the transfer of an undertaking for the purposes of the Employment Regulations and accordingly the contracts of employment of the Employees will have effect from the Option Completion Date as if originally made between the Employees and the Buyer.

26.1.2 those Employees who are in contributing service under the BECG immediately before the Option Completion Date shall continue in contributing service under the BECG on the same terms from the Option Completion Date (although this shall not be construed so as to prevent the Buyer from subsequently providing benefits applicable under the BECG for the Employees under a different arrangement);

26.1.3 the Buyer shall be deemed (for the purposes of the rules of the ESPS applicable to the BECG and all related purposes) to have become the employer or last employer of all those members and former members associated with the BECG who are not Employees but whose employer immediately prior to ceasing active membership of the BECG for the last time was the Seller; and

26.1.4 the Existing Principal Employer (and each other Seller’s Group Company that has participated in the BECG before the Option Completion Date) shall be discharged from all functions, duties, obligations and liabilities whatsoever in

This indemnity shall survive termination of this Agreement.

26.4 From the Option Completion Date, the Seller shall indemnify, and keep indemnified, the Buyer on demand against each loss, liability and/or cost which the Buyer incurs, or which is asserted against or demanded from the Buyer, under or in relation to the BECG in respect of those members of the BECG whose employer immediately prior to their last ceasing active membership of the BECG before the Option Completion Date was not the Seller, and each loss, liability and/or cost incurred as a result of defending or settling a claim alleging such a liability. This indemnity shall survive termination of this Agreement.

27.2.2 prior to the Option Completion Date, the Seller provided the Buyer with information that is sufficient for the Buyer to be aware of the presence of Hazardous Substances at, in, on or under the Properties;

27.2.3 from the Option Completion Date, the Buyer shall be responsible for all and any Environmental Liabilities associated with the Properties (whether such Environmental Liabilities arise before or after the Option Completion Date);

27.2.4 both the Seller and the Buyer are large commercial organisations;

27.2.5 the Property is sold in its existing state and condition at the Option Completion Date (including the presence of any Hazardous Substances) and no warranty is given as to such state and condition or its suitability for any purpose and function;

27.2.6 The agreements and acknowledgements in Clauses 27.2.1 to 27.2.5 (both inclusive) above are made in accordance with statutory guidance under Part IIA of the Environmental Protection Act 1990 to exclude the Seller as an appropriate person to bear responsibility for environmental liability in relation to or derived from the Properties; and

28. ENVIRONMENTAL INDEMNITY

28.1 On and after the Option Completion Date, the Buyer shall indemnify the Indemnified Parties on demand in relation to all Environmental Losses (except to the extent that these arise as a consequence of any breach of the Credit Agreement and have not been compensated for by an adjustment to the Break Fee). This indemnity shall survive termination of this Agreement.

29. PERMITS

29.1 After the Option Time, the Buyer and the Seller shall use reasonable endeavours (each at their own cost and expense) to have the Environmental Permits transferred or novated to the Buyer (or its nominee) on the Option Completion Date, provided that the transfer of such Environmental Permits shall not take place until the authorisation issued under Part 1 of the Environmental Protection Act 1990 or the authorisation issued under the Prevention, Pollution and Control Act 1999 in respect of the Station has been transferred to the Buyer (or its nominee).

29.2 After the Option Time, the Seller and the Buyer shall use best endeavours to procure that the Buyer completes the transfer of the Gale Common Permit to the Buyer (or its nominee) on the Option Completion Date if reasonably possible but if not as soon as reasonably practicable thereafter.

**** indicates material omitted and filed separately with the Commission.

32

29.3 If the transfer of the Gale Common Permit to the Buyer (or its nominee) does not take place on the Option Completion Date, until the transfer is achieved the Seller shall at the Buyer’s sole cost and risk delegate so far as it may lawfully do, its duties in relation to Gale Common to the Buyer (or its nominee) and the Buyer shall be responsible for all liabilities, costs and/or expenses in employing the site manager and other personnel during this period.

29.4 The Buyer shall indemnify the Seller and hold the Seller harmless for all liabilities, costs and/or expenses arising in respect of Gale Common or the Gale Common Permit or an Environmental Permits from the Option Completion Date including any costs, liabilities and/or expenses related to carrying out any of its remaining responsibilities and duties at Gale Common. This indemnity shall survive termination of this Agreement.

30. TAX

30.1 The Seller hereby agrees that upon being given evidence reasonably satisfactorily to it that the Buyer has, solely as a result of the grant (but not the actual exercise or completion) of the Option, paid stamp duty in respect of this Agreement or has accounted for stamp duty land tax in respect of the grant of the Option, the Seller will within 10 Business Days reimburse to the Buyer the amount of such stamp duty or (as the case may be) stamp duty land tax. If the Seller so requests, the Buyer will use all reasonable endeavours to assist the Seller to minimise the stamp duty or stamp duty land tax due on the grant of the Option. For the avoidance of doubt, all stamp duty or stamp duty land tax due in respect of the exercise of the Option or Completion shall be paid by the Buyer and will not be reimbursed by the Seller. If the Buyer so requests, the Seller will use all reasonable endeavours to assist the Buyer to minimise the stamp duty or stamp duty land tax due on exercise of the Option.

30.2 Upon exercise of an Option, the Buyer shall, subject to Clause 30.3, at the written request of the Seller in a timely manner join in an election under section 198 Capital Allowances Act 2001 on such terms as the Seller may reasonably require.

30.3 The Seller shall allocate the consideration for the Business and the Station Assets as follows: (a) to inventory and current assets if any - the Seller’s book value; (b) to assets in respect of which expenditure is eligible for capital allowances under Part 2 Capital Allowances Act 2001 - not less than £50,000,000 but provided it is not less than £50,000,000, such amount as shall ensure the Seller neither suffers a balancing charge nor obtains a balancing allowance in respect of the disposal; and (c) to other assets - such amount as the Seller proposes and that ensures the Seller neither makes taxable revenue profit nor incurs an allowable revenue loss in respect of the disposal. The Seller shall ensure any election as referred to in Clause 30.2 or apportionment under Clause 7.2 or 8.2 shall be consistent with this Clause 30.3. The Seller will deliver a draft allocation of consideration for the Business and Station Assets to the Buyer and give the Buyer a reasonable opportunity to review it before delivering a final allocation. The Buyer may make representations to the Seller as to the draft allocation of the consideration and the Seller shall adjust the allocation as required by the Buyer before producing a final allocation provided that such

**** indicates material omitted and filed separately with the Commission.

33

revised allocation can properly be made and does not give rise to any Tax liability for the Seller greater than that (if any) in the Seller’s original allocation.

31. RELEASE OF GROUP COLLATERAL

31.1 From the Option Completion Date, the Buyer shall be responsible for the giving of any cash collateral, financial or other guarantee, indemnity, undertaking or bond (as the case may be) as required under or in respect of:

31.1.1 the Industry Documents;

31.1.2 the Gale Common Permit; and

31.1.3 the Heavy Fuel Oil Agreement

32.2 If the Buyer or the Seller makes a deduction or withholding required by law from a payment (other than a payment of interest) under this Agreement, the sum due from that party shall be increased to the extent necessary to ensure that, after the making of any deduction or withholding, the party to whom such amount is payable (including an Indemnified Party or Indemnified Parties) receives a sum equal to the sum it would have received had no deduction or withholding been made.

32.3 If a payment under this Agreement will be or has been subject to Tax, the Buyer or the Seller (as the case may be) making such payment shall pay to the party to whom such amount is payable (including an Indemnified Party or Indemnified Parties) the amount (after taking into account Tax payable in respect of the amount) that will ensure that the party to whom such amount is payable (including an Indemnified Party or Indemnified Parties) receives and retains a net sum equal to the sum it would have received had the payment not been subject to Tax.

32.4 Nothing in this Clause 32 shall effect any obligation of the Escrow Agent which shall be governed instead by Clause 32.

34.2 If notwithstanding Clause 34.1 value added tax is chargeable on the transfer of the Business or any of the Station Assets under this Agreement, the Buyer shall (against delivery of tax invoices in respect of the Business or any of the Station Assets respectively) pay the amount equal to any penalty or interest incurred by the Seller for the late payment of value added tax resulting from any failure or delay by the Buyer in making payment as required by this Clause 34.2.

34.3 At Completion the Seller shall give the Buyer all records referred to in section 49 of the VATA. After Completion the Seller shall not make a request to H.M. Customs & Excise for the records to be taken out of the Buyer’s custody. During the period for which the records are required to be preserved under paragraph 6 of Schedule 11 to the VATA (duty to keep records), the Buyer shall give the Seller reasonable access to the records for the purpose of inspecting, and making copies of, them.

35.1 If at any time any provision of this Agreement is or becomes illegal, invalid or unenforceable in any respect under the law of any jurisdiction (a “Relevant Event”), that shall not affect or impair:

(a) a breach of the obligations imposed by this letter by you (or by any person to whom disclosure of information is made as permitted under this letter); or

(b) a breach by you (or any other such person) of any other duty of confidentiality relating to that information.

1.5 You will procure that each person to whom disclosure of Information is made as permitted under Sub-paragraph 1.4 is made aware (in advance of disclosure) of the terms of this letter and you will procure that each such person provides a confidentiality undertaking to you on substantially the same terms as this undertaking and also includes an express acknowledgement and confirmation that such person extends the terms of such undertaking for the benefit of each member of the Group; and

1.6 You will promptly notify EPL in writing if any Information is required to be disclosed by law or other regulation or any stock exchange whether in the United Kingdom or elsewhere and cooperate with EPL or its ultimate parent regarding the timing and content of such disclosure or any action which EPL or its ultimate parent may reasonably elect to take to challenge the validity of such requirement.

2. You further acknowledge and confirm to EPL that:

2.1 Your obligations under this letter shall extend to protect each and every member of the Group; and

2.2 Your obligations under this letter shall be continuing for a period of two years from the date of this letter, in particular they shall survive the termination of any discussions or negotiations between you, EPL, and each other member of the Group and the Banks regarding the Plant.
