No administrator of the Seller has been appointed by any person entitled to appoint such an administrator pursuant to Schedule B1 to the Insolvency ▇▇▇ ▇▇▇▇, nor have any documents been filed with the Court for the appointment of such an administrator, and not has any notice of intention to appoint such an administrator been given by any such person. No composition in satisfaction of the debts of the Seller, scheme of arrangement of its affairs or its members or both, or any class of either its creditors or members or both, has been proposed, sanctioned or approved. No distress, distraint, charging order, garnishee order, execution, or other process has been levied or applied for in respect of the whole or any part of the Interests. No event has occurred causing, or which on intervention or notice by any third party may cause, any floating charge created by the Seller to crystallise over the Interests or any part of them, not any charge created by it to become enforceable over the Interests or any of them, nor has such crystallisation occurred and nor is such enforcement in process.

6.11

Subject to the terms of this Agreement, the Purchaser hereby represents and warrants to the Seller as follows:

	6.11.1		The Purchaser is duly incorporated with limited liability and validly existing under the laws of England and Wales;
	6.11.2		The documents which contain or establish the Purchaser’s constitution incorporate provisions which authorise, and all necessary corporate action has been taken to authorise, the Purchaser to execute and deliver this Agreement and perform the transactions contemplated hereby;
	6.11.3		The signing and delivery of this Agreement and the performance of the transactions contemplated by this Agreement, will not contravene or constitute a default under any provision contained in any agreement, instrument, law, judgement, order, licence, permit or consent by which the Purchaser or any of its Affiliates or any of its assets is bound or affected;
	6.11.4		It will acquire the ▇▇▇▇▇ “as is, where is,” and with all faults; and
	6.11.5		No litigation, arbitration, administrative proceeding, dispute or judgement against the Purchaser or its Affiliates or to which the Purchaser or any of its Affiliates is a party which might by itself or together with any such other proceedings have a material adverse effect on the Purchaser’s or any of its Affiliates’ business, assets or condition and which would materially and adversely affect its ability to observe or perform its obligations under this Agreement and the transactions contemplated hereby, is subsisting or, so far as the Purchaser is aware, threatened or pending against the Purchaser or its Affiliates or any of its assets;

6.12

	6.12.1		A Warranty Claim by the Purchaser shall be limited to damages and the Purchaser’s claim for breach of any other provision of this Agreement shall be limited to damages or specific performance or injunction (or similar discretionary remedy) and in either case, the Purchaser shall not be entitled to any other form of remedy in relation thereto including rescission.
	6.12.2		Any damages recoverable by the Purchaser under this Agreement shall be assessed on the basis of:

	(a)		the diminution in value of the Interests in the case of a claim for breach of warranty or representation under this Agreement; or
	(b)		the direct loss, damage or expense incurred by the Purchaser in the case of a claim for breach of any other provision under this Agreement;

which in either case shall be directly attributable to the matter or circumstance giving rise to that claim and shall not in either case be taken to be greater than the Consideration.

6.13		The Seller shall not be liable for any Claim in relation to any Warranty Claim unless it shall have received from the Purchaser, as soon as practicable after the Purchaser becomes aware of the same, a notice containing reasonable details of the relevant Warranty Claim including the Purchaser’s provisional estimate of the amount of the Warranty Claim provided always that such notice is received on or before the date which is twelve (12) months after the Completion Date. Any such Warranty Claim made shall be deemed to have been withdrawn unless proceedings in respect thereof have been both issued and served on the Seller within three (3) months of the giving of such notice.
6.14		A breach of the Warranties which is capable of remedy shall not entitle the Purchaser to make a Warranty Claim unless the Seller is given notice of such breach and the Seller has failed:

	6.14.1		where the necessary remedial action consists of offshore operational activities, to commence any such physical remedial action involving operational activities within forty-five (45) days after the date on which such notice is served on the Seller and to work diligently to complete such remedial action; and otherwise
	6.14.2		to undertake and complete remedial action within thirty (30) days after the date on which such notice is served on the Seller,

provided that nothing in this Clause 6.14 shall require the Purchaser to defer making a Warranty Claim until after the period specified in Clause 6.13.

6.15

Except as set forth in Clause 6.10, neither the Seller nor any of its Affiliates nor any officer, shareholder, director, employees, agent, consultant, auditor or representative of the Seller or of any of its Affiliates makes any

representation, warranty or undertaking, statement, opinion, information or advice (including any representation, warranty, undertaking, statement, opinion, information or advice whether (a) communicated (orally or in writing) to the Purchaser or any Affiliate of the Purchaser or (b) made in any data, information or document communicated to the Purchaser or any Affiliate of the Purchaser, or made by any officer, shareholder, director, employee, agent, consultant, auditor or representative of the Seller or any of its Affiliates) and the Purchaser acknowledges, affirms and warrants that it has not relied, and will not rely, upon such representation, warranty, undertaking, statement, opinion, information or advice in entering into this Agreement or carrying out the transactions contemplated by this Agreement. Without limiting the generality of the foregoing, the Seller makes no representation or warranty as to: (i) the amounts, quality or deliverability of reserves of Oil, Gas or other Petroleum attributable to the Interests, (ii) any geological, geophysical, engineering, economic or other interpretations, forecasts or evaluations, (iii) any forecast of expenditures, budgets or financial projections, (iv) any geological formation, drilling prospect or hydrocarbon reserve, (v) the state, condition or fitness for purpose of any of the physical assets, including all onshore and offshore: installations, structures, platforms, pipelines, plant, equipment, machinery, ▇▇▇▇▇ and facilities related to the Interests and/or to operations under the Licence and or other Licensed Interest Documents, or (vi) the existing or future statutory or regulatory regime, including as to Taxation, applicable to the acquisition and operation of oil and gas properties, or (vii) market prices of Gas, Oil or other Petroleum.

6.16

The liability of the Seller (whether in contract, tort, including negligence, breach of duty, or otherwise) a Warranty Claim shall be limited as follows:

	6.16.1		there shall be disregarded for all purposes any Warranty Claim in respect of the amount of the damages to which the Purchaser would otherwise be entitled in respect of such Warranty Claim is less than One hundred thousand Pounds (£100,000);
	6.16.2		the Seller shall have no liability unless and until the damages to which the Purchaser is entitled in aggregate in respect of all Warranty Claims qualifying under Clause 6.16.1 exceed One million Pounds (£1,000,000) (in which case the Purchaser shall be able to claim for the whole amount of such claims and not just only the excess);

and

6.16.3

the maximum aggregate liability of the Seller in respect of all Warranty Claims, and any breach of any other provision of this Agreement shall not exceed an amount equal to 100% of the Consideration.

6.17

If:

	6.17.1		any circumstance arises which may result in the Purchaser having a Warranty Claim against the Seller as a result of or in connection with a liability or alleged liability to a third party; or
	6.17.2		the Purchaser is or may be entitled by law to recover from some other person, firm, authority or body corporate any sum in respect of which the Purchaser may have a Warranty Claim against the Seller, the Purchaser shall promptly notify the Seller thereof and unless the Purchaser also notifies the Seller that it withdraws the said Warranty Claim, the Seller shall be entitled (provided always that it does not act to unreasonably prejudice the business of the Purchaser) (i) to take and/or require the Purchaser to take any action the Seller might reasonably request to resist such liability or enforce such recovery in the name of the Purchaser but at the cost and expense of the Seller, and (ii) to have conduct of any appeal, dispute, compromise or defence of the dispute and of any incidental negotiations for the aforesaid purposes, and the Purchaser will give the Seller all co-operation, access and assistance for the purposes of resisting such liability or enforcing such recovery as the Seller may reasonably require.

6.18

If the Seller pays to the Purchaser an amount pursuant to a Warranty Claim, and the Purchaser is entitled to recover from some other person any sum to which it would not have been or become entitled but for the circumstances giving rise to such a Warranty Claim, the Purchaser shall promptly undertake all reasonable steps to enforce such recovery and shall forthwith repay to the Seller following such recovery so much of the amount paid by it as does not exceed the amount recovered from the third party, less all costs, charges and expenses reasonably incurred by the Purchaser in obtaining such recovery from the third party.

6.19		The Seller shall have no liability in respect of a Warranty Claim to the extent that is occasioned by the Seller doing or omitting to do any act or thing at the express written request of the Purchaser prior to Completion.
6.20		Nothing in this Agreement shall relieve the Purchaser of any duty, whether at common law or otherwise, to mitigate any loss or damage incurred by it in respect of any Warranty Claim.
6.21		The Purchaser shall not be entitled to recover from the Seller the same sum or loss more than once in respect of any Warranty Claim of any of them.
6.22		The Seller shall not be liable to the Purchaser for any Warranty Claim in respect of a breach of the Warranties, to the extent that:

6.22.1

the subject of such Warranty Claim has been fairly disclosed in this Agreement, the Licensed Interest Documents, the Data Room Documents or the Disclosure Letter with sufficient details to identify the nature and scope of the matter disclosed; or

6.22.2

allowance, provision or reserve has been made, for the benefit of the Purchaser, for such Warranty Claim in the Final Completion Statement.

6.23		Save as set out in this Agreement, the Seller shall not be liable to the Purchaser for any Warranty Claim or any of them to the extent such Warranty Claim was increased by or to the extent to which the Warranty Claim arose as a result of an act, omission or transaction carried out after the date hereof by the Purchaser or the Purchaser’s Associated Parties otherwise than:

	6.23.1		in the ordinary and usual course of business,
	6.23.2		in pursuance of a legally binding commitment entered into prior to the date hereof;

6.24		The Seller shall not be liable in respect of any Warranty Claim or any of them to the extent that such Warranty Claim is attributable to, or is increased as a result of, any legislation not in force at the date hereof or to any change of law, regulation, directive, requirement or administrative practice or any change in rates of tax, which in each case is not in force at the date hereof.
6.25		If any Warranty Claim or any of them shall arise by reason of some liability which at the time that the Warranty Claim is notified to the Seller is contingent only, the Seller shall not be under any obligation to make any payment in respect of such Warranty Claim until such time as the contingent liability ceases to be so contingent.
6.26		Notwithstanding any other provision of this Agreement, neither the Seller nor the Purchaser shall under any circumstances howsoever arising whether arising in contract or tort (including negligence, breach of duty, statutory or otherwise) be liable to the other Party under, arising out of or in any way connected with this Agreement or the Assignment Documents for any Consequential Loss.
6.27		If:

	6.27.1		the Seller makes a payment in respect of a Warranty Claim to the Purchaser (the “Damages Payment”);
	6.27.2		at any time after making the Damages Payment the Purchaser or any Associated Party of the Purchaser receives any sum other than from the Seller which would not have been received but for the matter or circumstance giving rise to that Warranty Claim (the “Third Party Sum”);
	6.27.3		the receipt of the Third Party Sum was not taken into account in calculating the Damages Payment; and
	6.27.4		the aggregate of the Third Party Sum and the Damages Payment exceeds the amount required to compensate the Purchaser in full for the loss or liability which gave rise to the Warranty Claim in question (such excess being the “Excess Recovery”),

the Purchaser shall, promptly following receipt of the Third Party Sum by it or its Associated Party, repay to the Seller an amount equal to the lower of (i) the Excess Recovery and (ii) the Damages Payment.

6.28		The Seller shall not be liable in respect of any Warranty Claim to the extent that any Taxation for which the Purchaser is now or in the future accountable or liable to be assessed is reduced or extinguished as a result of the matter giving rise to such Warranty Claim.
6.29		The Purchaser shall refrain from doing, and shall procure that its Affiliates shall refrain from doing, any act or thing (other than in the ordinary course of business) which may give rise to a Warranty Claim which would not otherwise arise.
6.30		None of the limitations in this Clause 6 shall apply to any Warranty Claim which arises (or to the extent that it is increased) as a consequence of fraud or fraudulent misrepresentation by the Seller or its Affiliates.
6.31		The Warranties set out in Clauses 6.10.1, 6.10.2, 6.10.3, 6.10.4, 6.10.5, 6.10.6(a), 6.10.7(a) and 6.10.9(a), shall be deemed to have been repeated immediately prior to Completion.
7.		Ongoing Obligations and Liabilities
7.1		At all times from the date hereof (including following Completion), the Seller and the Purchaser shall use all reasonable endeavours to obtain from the relevant authorities an irrevocable release of the Seller and each Affiliate of the Seller from its or their obligations and liabilities under the ▇▇▇▇▇▇▇▇▇ ▇▇▇ ▇▇▇▇ and all notices and regulations served and issued pursuant thereto (and under any antecedent legislation which is the subject of consolidation by the said Act), insofar as the same relate to the Interests. For the avoidance of doubt, the aforesaid obligation shall include procuring release from any subsequent notice or notices issued to the Seller or any of its Affiliates under section 29 of the ▇▇▇▇▇▇▇▇▇ ▇▇▇ ▇▇▇▇.
7.2		The Seller and the Purchaser shall co-operate with each other and execute and deliver to each other such other instruments and documents and take such other actions as may reasonably be requested from time to time in order to carry out, evidence and confirm their rights under, and the intended purpose of, this Agreement.
8.		Announcements
		Neither the Seller nor the Purchaser shall (and the Seller and the Purchaser will procure that no Affiliate shall) be entitled, without the prior written consent of the other, which consent can be withheld for any reason, to issue or make any public announcement or statement regarding this Agreement or any transactions contemplated hereby. Notwithstanding the foregoing provisions and the

provisions of Clauses 4.3 and 12, such provisions shall not apply to the extent that it is necessary for that Party or its Affiliate to make such public announcement or statement in order to comply with a statutory obligation, an obligation to include information in published or audited accounts, or with the requirement of a competent government agency, The London Stock Exchange, the Securities and Exchange Commission or other securities or regulatory body, or a recognised stock exchange on which that Party or such Affiliate has its shares or stock listed, in which event the Party proposing to make such an announcement or statement shall (and in the case of an Affiliate of such Party will procure that such Affiliate shall), where reasonably practicable, issue a draft thereof to the other Party prior to its release for approval which approval shall not be unreasonably withheld or delayed.

9.		Notices
9.1		Except as otherwise provided in this Agreement, any notice or other document to be given under this Agreement shall be in writing and shall be deemed to be duly given if it (or the envelope containing it) identifies the Party to which it is intended to be given as the addressee and, in the case of the Seller, is marked “for the attention of the Manager Business Development — Europe” or such other person as may be notified to the Purchaser by the Seller and, in the case of the Purchaser is marked “for the attention of the Director of Commercial Operations” or such other person as may be notified to the Seller by the Purchaser and it is:

10.3		The Purchaser shall be responsible for payment in a timely fashion of any and all Stamp Duty Land Tax payable on or in respect of this Agreement, the Assignment Documents, and in respect of its or their subject matter and any similar duties and charges wheresoever arising.
10.4		The Purchaser warrants to the Seller that it has incurred no liability, contingent or otherwise, for broker’s or finder’s fees in connection with this Agreement or the transaction contemplated by it for which the Seller will have any responsibility.
11.		Taxation
11.1		General

11.1.1

Notwithstanding any other provisions of this Agreement, the Seller shall retain access to all books, records and Operator’s information,

			which relate to the Interests for all periods prior to the Completion Date for the purposes of administering their Taxation affairs and as required by law. The Purchaser shall retain all such books, records and information received by the Purchaser.
	11.1.2		The Purchaser shall, as soon as reasonably practicable, ensure that the Seller is informed of all documentation relating to Taxation in respect of the Interests in periods prior to the Completion Date delivered to the Purchaser by the Operator (otherwise than by the Seller) and shall promptly deliver copies of such documentation which are reasonably required by the Seller for the purposes of the Seller’s Taxation affairs to the Seller.
	11.1.3		The Seller shall promptly provide the Purchaser with copies of any information or documents relating wholly or partly to the Interests for periods prior to the Completion Date which are reasonably required by the Purchaser for the purposes of the Purchaser’s Taxation affairs.

11.2		Allocation of Consideration
		The Parties agree that no part of the Consideration shall be treated as expenditure incurred by the Purchaser on either mineral exploration and access on which a first year allowance could be claimed under section 416B CAA2001 or plant and machinery on which first year allowances could be claimed under section 52 CAA2001.
11.3		Taxation on Post Completion Payments and Receipts
		Any payments or receipts made after Completion between the Parties, except for any payment under Clause 3.9, shall be adjusted for Taxation so as to produce the same economic result as required by Clause 2.1.
11.4		VAT

	11.4.1		All sums payable under this Agreement are exclusive of VAT, which will be added where applicable and will be payable by the Purchaser on production of a valid VAT invoice.
	11.4.2		The Purchaser and the Seller confirm that they are registered or registerable as taxable persons for the purposes of VAT as at the date of Completion.
	11.4.3		The Purchaser and the Seller confirm that no election has been made and confirm that no election will be made prior to the Completion Date under paragraph 2 schedule 10 Value Added Tax ▇▇▇ ▇▇▇▇ in relation to any of the Interests.
	11.4.4		Notwithstanding that the Parties believe that the sale and transfer hereunder is a transaction which is outside the scope of VAT by virtue of the Value Added Tax (Special Provisions) Order 1995, in the event that either the Purchaser or the Seller is advised in writing by HMRC after full disclosure of all material facts that the transaction hereunder is

			subject to VAT, the Purchaser undertakes that, if called upon to do so by the Seller, it will pay to the Seller on presentation by the Seller of a VAT invoice any amounts properly due in respect of VAT set out in such invoice within thirty (30) days of demand.
	11.4.5		Subject to Clauses 11.4.1 and 11.4.4, any Adjustments pursuant to Clause 3 or payments or reimbursements pursuant to Clause 6.2 will be subject to VAT where applicable. However, where payment is due by the Seller to the Purchaser, the Parties agree that where any such Adjustment, payment or reimbursement is made, there is no obligation to adjust the original VAT charge, provided the Purchaser was entitled to recover all the original VAT on the supply as input tax.
	11.4.6		Notwithstanding that the Parties believe that the sale and transfer hereunder is a transaction which is outside the scope of VAT by virtue of the Value Added Tax (Special Provisions) Order 1995, if the conditions under Article 5 thereof are not met the Parties believe that the sale and transfer contemplated hereby is a supply of services in relation to land situated outside the United Kingdom by virtue of the VAT (Place of Supply of Services) Order 1992 and is thus outside the scope of UK VAT.

11.5

Withholding Taxes

	11.5.1		The Seller shall, where required by UK law, withhold tax from any payments made to the Purchaser to the extent required by such law and, upon written request from the Purchaser, shall provide a withholding tax receipt or other documentary evidence of the withholding tax to the Purchaser.

Standard Oil Accounting Procedures (SOAP1)

3.3.1 Content and Format

The information required to support the budget proposal varies according to the phase of activity and type of expenditure. Materiality is the main criterion for the level of explanation required.

“Contingent” items should be clearly identified to avoid confusion as to what approval is being sought. Contingent items would need subsequent approval.

     The following information is recommended:

     § work programme and assumptions, including production details (if applicable);

     § phased expenditure, by quarter, by major classification or anticipated AFE for the budget year;

     § a forecast outlook at summary level for the current year plus the two years beyond the budget year.

     § Clear summary of contingent items.

     § Summary of carry over expenditure from prior year approved budgets.

3.3.1 Approvals

Exploration and Appraisal
(E&A)

Active licences, including all ▇▇▇▇▇ and major G&G projects, require AFE approval. Other costs, e.g. minor studies, licence rentals and overheads should be approved at the budget stage.

Transfers between budget categories are permitted up to a maximum of 10%, and will be reported in Management Information unless the total budget moves by more than the allowed (10%) tolerance, when formal approval is required.

All budgets should be expressed in sterling, but with co-ventures given the option of having major currency commitments shown separately.
