3. Consideration

3.1 The consideration for the sale and transfer by the Seller to the Buyer of the Option Interests shall be the payment by the Buyer to the Seller of a sum calculated using the following formula:

if X > 69.1p/therm, then the Purchase Price = £6,140,000 + [(X/69.1) x £66,250,000]

if X < 69.1p/therm, then the Purchase Price = £72,390,000

Where:

X = price in p/therm of gas as determined by the Tunnel as of the day before the day on which the Option is exercised

69.1 p/therm = price per therm of gas as determined by the Tunnel as of October 22, 2008

(the “Purchase Price”) (of which six million one hundred and forty thousand Pounds (£6,140,000) shall have been paid by the Buyer to the Seller upon exercise of the Option (the “Advance”) as adjusted pursuant to this Agreement (the “Consideration”).

3.2 Subject to Clause 12, the Consideration shall be allocated as set out in Schedule 2.

Adjustments

3.3 The Purchase Price shall be adjusted by the Adjustments which shall operate by way of increases or decreases, as the case may be, to the Purchase Price provided that no item taken into account in calculating any one of the Adjustments shall be taken into account in calculating any one of the other Adjustments so as to result in a Party making or receiving payment twice in respect thereof.

3.4 No adjustment under this Clause 3 shall be made in respect of any matter to which Clause 6.6 applies.

3.5 The Working Capital Adjustment, which if positive shall increase the Purchase Price and if negative shall reduce the Purchase Price, shall be the aggregate of the working capital balances in relation to the Option Interests calculated in respect of each of the categories listed in Schedule 3 as at the Economic Date by reference to the statements provided by the Operator and otherwise in accordance with Schedule 3. Such working capital balances shall be prepared in accordance with proper accounting and operating procedures and otherwise in accordance with good oil and gas field practice.

3.6 The Cash Calls Adjustment, which shall increase the Purchase Price, shall be the sum of all cash calls or billing invoices paid in respect of the Option Interests by the Seller during and/or in respect of the Interim Period and which, using the Accruals Basis of Accounting, relate to periods beginning on or after the Economic Date pursuant to the Licensed Interest Documents.

3.7 The Petroleum Sales Adjustment, which shall decrease the Purchase Price, shall be the notional value of the Gas produced in respect of the Option Interests in each day of the Interim Period based on multiplying the volume of such Gas by the Market Price for such Gas and for this purpose the Market Price shall be calculated as follows:

Market Price = (0.25 x MP) + (0.75 x DP)

22

where:

“DP” means the applicable gas index price for Day D expressed in xxxxx per therm based on the arithmetic average of the Day ahead NBP bid prices and the Day ahead NBP offer prices for Natural Gas (in xxxxx per therm) published by Heren on the preceding Day (D-1).

In case of a Banking Day following a weekend or a public holiday the arithmetic average of the Day ahead NBP bid prices and the Day ahead NBP offer prices published by Heren on the last Banking Day before the weekend or public holiday shall be used.

In the case of a weekend and a public holiday immediately preceding or following a weekend then the arithmetic average of the Heren weekend NBP bid prices and the weekend NBP offer prices on the preceding Banking Day for that weekend shall be used.

In the case of a public holiday mid week the arithmetic average of the special NBP bid prices and special NBP offer prices for that period published by Heren on the preceding Banking Day shall be used, provided that if no such prices are published then the weekend NBP bid prices and weekend NBP offer prices for that period published by Heren on the preceding Banking Day shall be used.

“Heren” means Heren Energy in European Spot Gas Markets.

“MP” means the applicable gas index price for Month M (expressed in xxxxx per therm) based on the arithmetic average of the month- ahead NBP bid prices and the Month ahead NBP offer prices for Natural Gas (in xxxxx per therm) for Month M as published by Heren for each day of publication in Month M-1 which are then averaged over the number of days in which prices are published.

3.8 The Interim Period Adjustment, which shall increase the Purchase Price, shall be the sum of all expenditure incurred by the Seller, using the Accruals Basis of Accounting, in respect of the Option Interests during the Interim Period, including demurrage, brokers’ fees (other than fees of advisers engaged in relation to the matters referred to herein), insurance premia and deductibles, rent and licence fees and all other costs and expenses incurred by the Seller in respect of the Option Interests which are in respect of the period on and after the Economic Date and which have not been met by cash calls or other payments taken into account under the foregoing provisions of this Clause 3 or Clause 12 provided that any such expenditure relating to any period prior to the Economic Date which has not been taken into account in the Working Capital Adjustment shall be for the account of the Seller.

3.9 Where any sums payable by the Buyer to the Seller or by the Seller to the Buyer pursuant to Clauses 3, 6, 7 or 12 are expressed in Sterling, the same shall be paid in Sterling.

23

Payment of disputed amounts or portions thereof shall be made within five (5) Business Days following agreement of the Parties or determination under Clause 3.13.

If the Parties fail to agree the Final Completion Statement within fifteen (15) Business Days of receipt by the Buyer, the Final Completion Statement shall be referred for determination in accordance with the provisions of Clause 3.13. The agreed or determined amounts, to the extent not already paid or taken into account on Completion, shall be paid by the Buyer. Payment of agreed or disputed amounts or portions thereof shall be made within ten (10) Business Days following either agreement of the Parties or determination under Clause 3.13 (as the case may be).

3.13 If the Parties cannot reach agreement on the contents of all or part of the statements referred to in Clauses 3.10 and/or 3.12 within the time limit provided in Clause 3.12, the disputed items may be referred by either the Seller or the Buyer for determination by an independent chartered accountant nominated by the Parties or, in the absence of agreement between the Parties within ten (10) Business Days of a Party notifying the other that it proposes to refer the dispute to an independent chartered accountant, by the President of the Institute of Chartered Accountants in England and Wales on the application of such Party. The nominated chartered accountant shall be afforded such access to books, records, accounts and documents in the possession of the Parties as he may reasonably request, and he shall act as expert not as arbitrator.

3.14 The Interim Completion Statement and the Final Completion Statement will be prepared on the information available at the time of their preparation and shall be without prejudice to any further claims arising under Clauses 6, 7 and/or 12 after the time of the preparation of such statements.

24

Statement and the Seller shall provide to the Buyer, as soon as reasonably practicable, all the Seller’s calculations (and supporting documents) in the preparation of the Adjustments for verification purposes including such explanations and methodology as the Buyer shall reasonably require. Without prejudice to the generality of the foregoing, subject to and to the extent of any confidentiality obligations by which it is bound, the Seller shall provide the Buyer with copies of all Operators’ reports, billing statements and correspondence and any other relevant documentation in its possession necessary to support the Interim Completion Statement and the Final Completion Statement. Where the Seller is unable to provide the Buyer with such information due to confidentiality obligations by which it is bound it shall provide the same to an independent chartered accountant for the purposes of certifying the accuracy of such information to the Buyer.

Time-value adjustments

3.15 An amount equivalent to interest (calculated on a compounded basis on the accumulated daily balances) at the Agreed Rate shall be payable on the Purchase Price from the Economic Date up to the Completion Date (both dates inclusive).

3.16 In respect of the Adjustments, an amount equivalent to interest (calculated on a compounded basis on the accumulated daily balances) at the Agreed Rate shall be payable (and in the case of clauses 3.16.3 and 3.16.4 below be taken into account in the calculation of the relevant Adjustment) on each of:

3.16.1 the Working Capital Adjustment from the Economic Date up to and including the Completion Date, and, in the case of final adjustments or disputed items, thereafter up to and including the date of settlement thereof;

7.8.2 individual claims with a value of less than two hundred and fifty thousand Dollars ($250,000) shall be disregarded for all purposes including for the calculation of the aggregate value of claims for the purposes of Clause 7.8.1; and

7.9.2 the Buyer is or may be entitled by law to recover from some other person any sum in respect of which the Buyer may have a claim against the Seller under this Clause 7,

the Buyer shall promptly notify the Seller thereof in writing and the Buyer shall make no admission of liability, agreement, settlement or compromise with any third party in relation to any such liability or alleged liability without the prior written consent of the Seller and the Seller shall at its expense be entitled to take and/or require the Buyer to take any action the Seller might reasonably request to prevent a claim arising or to resist such liability or enforce such recovery (as the case may be) and to have conduct of any appeal, dispute, compromise or defence and of any incidental negotiations for the aforesaid purposes, subject to indemnifying the Buyer in terms reasonably acceptable to the Buyer against any Losses and Expenses the Buyer may incur, and the Buyer will give the Seller all practicable co-operation, access, assistance and information for the purposes of preventing such a claim, resisting such liability or enforcing such recovery as aforesaid.

If the Seller pays to the Buyer an amount pursuant to a claim in respect of any breach of the Warranties and the Buyer 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 claim, the Buyer shall promptly undertake all appropriate steps to enforce such recovery and shall forthwith repay to the Seller the amount recovered from the third party or, if less, the amount paid by the Seller, less any costs and expenses reasonably incurred by the Buyer in recovering that amount from the third party.

7.11 The Seller shall not be liable for any breach of any provision of this Clause 7 nor shall the Buyer have any rights in respect of any inconsistency therewith arising after the date hereof, to the extent that such breach or inconsistency is occasioned by the Seller doing or omitting to do any act or thing at the written request of the Buyer.

7.12 A breach of warranties under Clause 7.1 or Clause 7.2 which is capable of remedy shall not entitle a Party to make a claim unless the warrantor is given notice of such breach and the warrantor has failed to commence remedial action within thirty (30) days after the date on which such notice is served on the warrantor. Without prejudice to the foregoing, if any claim shall arise by reason of some liability which at the time that the claim is notified to a Party is contingent only, such Party shall not be under any obligation to make any payment in respect of such claim until such time as the contingent liability ceases to be so contingent.

7.13 Where a representation or warranty is qualified by the words “so far as the Seller is aware”, or any similar expression, such representation or warranty is given only to the extent that any of the officers or directors of the Seller or ATP Oil & Gas Corporation or senior managers of the Seller have actual knowledge of the matters to which it refers as at the date the representation or warranty is given after due and careful inquiry only of those of the Seller’s senior employees directly engaged in the management of the Option Interests and who could reasonably be expected to have knowledge of the subject matter of the relevant representation or warranty (and no other persons).

7.14 Nothing in this Agreement shall relieve a Party of any duty, whether at common law or otherwise, to mitigate any loss or damage incurred by it in respect of any breach by the other Party of the representations, warranties, indemnities or any other term of this Agreement or in respect of its subject matter.

37

7.15 A Party shall not be entitled to recover from the other Party the same sum or loss more than once in respect of any claims for any breach of any provision of this Agreement or in respect of its subject matter.

7.16 Notwithstanding any other provisions of this Agreement, neither Party shall be liable to the other Party under, arising out of or in any way connected to this Agreement or the Assignment Documents, for any Consequential Loss, whether arising in contract or in tort (including negligence, breach of statutory duty or otherwise). For these purposes “Consequential Loss” means loss of revenue, production or profits; or inability to produce Petroleum; or losses associated with business interruption; or loss of bargain, contract (other than this Agreement), expectation or opportunity; or any loss, claim or expense which arises out of the delay, postponement, interruption to or inability to produce, deliver or process production from the Option Interests; or any increase in operating or other costs; or all indirect or consequential losses or damages howsoever caused or arising.

10.4 For the purposes of this Clause 10 “notice” shall include any request, demand, instructions or other document.

11 Costs and Expenses

11.1 Save as otherwise stated in this Agreement, each Party shall pay its and its Affiliates’ own costs, expenses, duties and, except as otherwise expressly agreed in writing, Taxation in relation to the preparation and execution of this Agreement, the documents contemplated hereby or executed pursuant hereto and any transactions contemplated by this Agreement.

11.2 Without prejudice to any other rights or remedies available to a Party hereunder or at law, if any amount payable hereunder is not paid when due, the defaulting Party shall pay interest on such amount from the due date of payment (after as well as before judgment) at a rate equal to two percent (2%) above the Agreed Rate calculated on a compounded basis on the accumulated daily balances.

11.3 The Buyer shall be responsible for payment in a timely fashion of any and all stamp duty land tax, stamp duties, transfer taxes, registration fees and other charges payable on or in respect of this Agreement, the Assignment Documents and/or any related agreements and in respect of its or their subject matter and any similar taxes, duties, fees and charges wheresoever arising in relation to the transfer of the Option Interests to the Buyer.

12 Taxation

12.1 The Seller confirms that it is registered and the Buyer confirms that it has applied for registration and will use its reasonable endeavours to obtain registration before Completion, as taxable persons for the purposes of VAT and that no election has been made and no election will be made prior to the Completion Date under paragraph 2 of Schedule 10 to the Value Added Tax Xxx 0000 in relation to the Option Interests.

12.2 The Buyer undertakes that it will use the Option Interests as part of its business of searching for, boring for and getting petroleum as a going concern for a sufficient period to comply with the requirements of Article 5 of the Value Added Tax (Special Provisions) Order 1995 so that the assignment of the Option Interests is treated as neither a supply of goods nor a supply of services for VAT purposes.

12.3 The Purchase Price is stated net of any applicable VAT. The Parties believe that the sale and transfer hereunder is a transaction which is outside the scope of VAT by virtue of Article 5 of the Value Added Tax (Special Provisions) Order 1995 and/or that the transfer contemplated hereby is of a right over land situated outside the United Kingdom and as such will be treated as outside the scope of Value Added Tax by virtue of Article 5 of the Value Added Tax (Place of Supply of Services) Order 1995. However, in the event that a Party is advised in writing by HM Revenue and Customs that the transaction hereunder is subject to VAT, the Buyer undertakes to pay to the Seller, on delivery of a valid VAT invoice, any amounts due in respect of VAT within thirty (30) days of demand.

41

12.4 Reimbursement pursuant to Clause 6.3 shall be exclusive of VAT which the Party receiving the reimbursement may be required to charge and, if called upon to do so by the such Party, the Party making the reimbursement undertakes to pay such Party, on presentation of a valid VAT invoice, any amounts properly due in respect of VAT set out in such invoice within thirty (30) days of demand.

12.5 Subject to Clause 12.3, any Adjustments pursuant to Clause 3 or payments or reimbursements pursuant to Clause 6.3 or Clause 7 in respect of any payment or receipt being an amount in respect of which VAT has been paid or received shall be made on a basis disregarding the VAT element where the VAT paid is fully deductible or is required to be accounted for in full to HM Revenue and Customs, but otherwise shall be made on a basis which leaves the Seller and the Buyer in no better and no worse a position (after taking account of VAT, and subject to the application of the other provisions of this Clause 12) than had the payment or receipt not been made or received.

12.6 The Seller shall make an application to HM Revenue and Customs under Section 49(1) (b) of the Value Added Tax Xxx 0000 for a direction that the records relating to the Option Interests which under paragraph 6 of Schedule 11 to the Value Added Tax Xxx 0000 have been maintained by the Seller or its Affiliates should be preserved by the Seller or its Affiliates, as the case may be, notwithstanding the provisions of the said section. The Seller shall, as soon as reasonably practicable following receipt thereof, provide the Buyer with a copy of any such direction and the Buyer shall retain access at all reasonable times during business hours to all books and records retained by the Seller or its Affiliates in relation to VAT matters concerning the Option Interests and the Seller covenants to retain such records as required by paragraph 6 of Schedule 11 to the Value Added Tax Xxx 0000.

12.7 CT Adjustments

12.7.1 The Purchase Price shall be increased by the Buyer paying to the Seller an amount equal to any CT paid by the Seller on any receipts taken into account, using the Accruals Basis of Accounting, for the purposes of Clause 3.7, the Petroleum Sales Adjustment.

12.7.2 The Purchase Price shall be decreased by the Seller paying to the Buyer an amount equal to any CT relief received by the Seller on any cash calls paid and any expenditure taken into account, using the Accruals Basis of Accounting, for the purposes of Clause 3.6, the Cash Calls Adjustment and Clause 3.8, the Interim Period Adjustment.

12.7.3 The Parties recognise that adjustments under this Clause 12.7 are notional adjustments, as opposed to actual payments of, reliefs from or reductions in CT liabilities. For the purpose of calculating these notional adjustments it shall be assumed that both the Seller and the Buyer are single companies with no brought forward losses who are paying CT at the standard rate applicable for the period concerned. Such notional adjustments shall be effected by deducting from each relevant payment a notional CT charge. In calculating the notional CT charge, the CT rate to be used will be the rate which applies at the end of the month in which the receipt or payment arises, or if the rate of CT changes during a month the arithmetic mean of the rates applicable for that month shall be used.

42

12.7.4 If the Parties cannot reach agreement on all or part of the adjustments referred to in this Clause 12.7 within thirty (30) Business Days of receipt by the Buyer from the Seller of the Seller’s estimate of such adjustments, the adjustments in dispute may be referred by either the Seller or the Buyer for determination by an independent expert nominated by the Parties or, in the absence of agreement between the Parties within five (5) Business Days of a Party notifying the other that it proposes to refer the dispute to an expert, by the President of the Institute of Chartered Accountants in England and Wales on the application of either the Seller or the Buyer. Within twenty (20) Business Days after the appointment of such expert, each Party may submit to the expert a statement of the nature of the dispute, a description of the submitting Party’s claims with respect thereto, and any other supporting documentation or materials with respect thereto that the submitting Party desires the expert to consider. The Party submitting such statement shall provide a copy thereof to the other Party, who shall have ten (10) Business Days from receipt thereof to submit a responding statement to the expert. The nominated expert shall be afforded such access to books, records, accounts and documents in the possession of the Parties as he may reasonably request, and he shall act as expert not as arbitrator. The said expert’s determination shall, in the absence of fraud or manifest error or bias, be final and binding on the Parties, his fees and disbursements shall be borne by the Seller and the Buyer in equal shares and the Parties shall bear their own costs in respect of such reference.

12.8 The Seller shall be liable for any liabilities arising under Schedule 15 to the Finance Xxx 0000 in respect of the Option Interests or the Licence(s) for periods ending up to the Economic Date and the Buyer shall be liable for all periods thereafter.

12.9.1 The Seller and the Buyer agree that the allocation of Consideration set out in Schedule 2 is a just and reasonable apportionment of the Consideration and both agree to submit their CT returns for all relevant years on the basis of said allocation. Further, the Seller and the Buyer agree consistently to allocate the Consideration attributable to amounts eligible for capital allowances between plant and machinery allowances and mineral extraction allowances on their respective CT returns. Where HM Revenue and Customs does not agree with the claim for capital allowances by the Buyer, the allocation set out in Schedule 2 shall be adjusted to take into account the just and reasonable apportionment agreed by HM Revenue and Customs and to reflect any revised disposal proceeds taken into account in the Seller’s revised CT returns.

12.9.2 If any part of the Consideration allocated as set out in Schedule 2 to assets qualifying for capital allowances under Part 2 and/or Part 5 of the Capital Allowances Act 2001 is not agreed by HM Revenue and Customs and the total of the capital allowances claim of the Buyer is reduced, the Seller shall pay to the Buyer, by way of adjustment to the Purchase Price, an amount equal to fifty percent (50%) of the amount by which the total of the Buyer’s claim for capital allowances is reduced by HM Revenue and Customs provided always that, save in the case of fraud or wilful concealment of material facts, the Seller shall not be liable for any payment to the Buyer pursuant to this Clause 12.9.2 unless it shall have received from the Buyer, as soon as practicable after the Buyer becomes aware of the amount of capital allowances not being so agreed, written notice containing reasonable details of the relevant claim including the Buyer’s bona fide provisional estimate of the amount of the claim and in any event such notice is received on or before 31^st March 2014. Any payment under this clause shall not be due for payment until the earlier of 1^st January 2012 and the date on which the increased Taxation that results from the adjustments to the allocation of consideration falls due for payment to HM Revenue and Customs.
