st March 2014. Any claim made shall be deemed to have been withdrawn or satisfied unless arbitration proceedings in respect thereof have been
both issued and served on the Seller within six (6) months of the giving of such notice. 


  

	7.6	Except as set out in Clause 7.1, neither the Seller nor any of its Affiliates nor any officer, shareholder, director, employee, agent, adviser, consultant or representative of the
Seller or any of its Affiliates (including their auditors) makes any representation, warranty, statement, opinion, information or advice (including any representation, warranty, statement, opinion, information or advice (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,
adviser, consultant or representative of the Seller or any Affiliate of the Seller) and the Purchaser acknowledges, affirms and warrants that (except as aforesaid) it has not relied, and will not rely, upon any such representation, warranty,
statement, opinion, information or advice of any person 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 hydrocarbons attributable to the Interests, (ii) any geological, geophysical, technical, 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, or (v) the physical state or condition of any of the assets associated with
the Interests and the Purchaser acknowledges that all such assets are to be acquired by the Purchaser on an “as is, where is” basis. 

  

	7.7	Save in the case of fraud or wilful concealment of material facts, the Purchaser shall not be liable for any claim in relation to any breach of the provisions of Clause 7.2 unless
it shall have received from the Seller, as soon as practicable after the Seller becomes aware of the same, written notice containing reasonable details of the relevant claim including the Seller’s bona fide provisional estimate of the amount of
the claim and in any event such notice is received on or before the expiry of twelve (12) months from the Completion Date. Any claim made shall be deemed to have been withdrawn or satisfied unless judicial proceedings in respect thereof have
been both issued and served on the Purchaser within six (6) months of the giving of such notice. 

  

	7.8	Save in the case of fraud or wilful concealment of material facts or breach of the Warranty contained in Clause 7.1.19, the liability of the Seller in respect of any claim for
breach of the Warranties shall be limited as follows: 

  

	 	7.8.1	the Seller shall have no such liability unless the total loss or damage claimed to have been suffered by the Purchaser (acting in good faith) in respect thereof when aggregated with
other such claims amounts to two million Dollars ($2,000,000) or more, whereupon the whole of such liability and not merely the excess shall be recoverable; and 

  

 25 









	 	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 

  

	 	7.8.3	the maximum aggregate liability of the Seller in respect of all such claims (including interest and expenses) shall not exceed an amount equal to the Purchase Price.


  

	7.9	If: 

  

	 	7.9.1	the Purchaser becomes aware of any circumstance which may result in the Purchaser having a claim against the Seller under this Clause 7 as a result of or in connection with a
liability or alleged liability to a third party, or 

  

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


 the Purchaser shall promptly notify the Seller thereof in writing and the Purchaser 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 Purchaser 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 Purchaser in terms reasonably acceptable to the Purchaser against any Losses and Expenses the Purchaser may incur, and the Purchaser 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. 
  

	 	7.10	Where the Purchaser is or may be entitled to recover from some other person any sum in respect of any liability, loss or damage the subject of a claim by the Purchaser against the
Seller in respect of any breach of the Warranties or for which such a claim could be made, the Purchaser shall, before seeking to recover any amount from the Seller under this Agreement, take all reasonable steps as the Seller may reasonably require
to enforce such recovery and shall keep the Seller informed of the progress of any action taken and any claim against the Seller shall be limited (in addition to the limitations on the liability of the Seller referred to in this Clause 7) to the
amount by which the loss or damage suffered by the Purchaser as a result of such breach shall exceed the amount so recovered. If the Seller pays to the Purchaser an amount pursuant to a claim in respect of any breach of the Warranties 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 claim, the Purchaser 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 Purchaser 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 Purchaser 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 Purchaser. 

  

 26 









	 	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 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. 

  

	 	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 Interests; or any increase in operating or other costs; or all indirect or consequential losses or damages howsoever caused or arising. 

  

	8	Ongoing obligations and liabilities 

  

	 	8.1	The Parties shall co-operate with each other and shall execute such documents and take such actions as may reasonably be requested from time to time in order to give full effect to
the intent of this Agreement. 

  

	 	8.2	Each Party undertakes to provide written advice to the other Party of any event giving rise to an adjustment under Clause 6, Clause 7 or Clause 12.7 or Clause 12.9.2, including such
documentary evidence as is reasonably deemed to be necessary by the other Party to verify the adjustment, within thirty (30) days of becoming aware of such an event. 

  

 27 









	9	Announcements and Confidentiality 

  

	9.1	No Party shall, and each Party shall procure that none of its Affiliates shall, issue or make any public announcement or statement regarding this Agreement or any transactions
contemplated hereby without the prior written consent of the other Party, such consent not to be unreasonably withheld or delayed, except to the extent that it is necessary for a 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 or other regulatory body, the London Stock Exchange plc, the Securities
and Exchange Commission of the United States of America or a recognised stock exchange on which that Party or such Affiliate has its shares or oil production or royalty stock listed, in which event the Party proposing to make such an announcement or
statement shall, as soon as practicable and, if possible prior to its release, issue a copy thereof to the other Party. In all circumstances the Parties shall consult in relation to the form of the announcement. 

  

	9.2	The terms and conditions of this Agreement shall be held confidential by the Parties and all information furnished or disclosed to a Party in connection with the transactions
contemplated by this Agreement (“Confidential Information”) whether before or after the date hereof shall be held confidential by such Party and neither the terms of this Agreement nor any Confidential Information shall, subject to
Clause 9.1, be divulged in any way to any third party by one Party without the prior written approval of the other Party; provided that such Party may, without such approval, disclose the same to:- 

  

	 	9.2.1	any of its Affiliates provided such Party remains liable for any breach of confidentiality by such Affiliate(s); or 

  

	 	9.2.2	any outside professional consultants or other professional advisers consulted in connection with this Agreement (including an expert and/or accountant appointed hereunder) provided
such Party obtains a similar undertaking of confidentiality (but excluding this proviso) from such consultants and advisers; or 

  

	 	9.2.3	any bank or financial institution from whom such Party is seeking or obtaining finance, provided such Party obtains a similar undertaking of confidentiality (but excluding this
proviso) from such bank or institution; or 

  

	 	9.2.4	the extent required by any applicable laws, the Licence(s), or the requirements of any recognised stock exchange or the Securities and Exchange Commission of the United States of
America in compliance with its rules and regulations; or 

  

	 	9.2.5	the extent required by any Government agency or authority lawfully requesting the same; or

this undertaking. 

  

	9.3	Notwithstanding the termination of this Agreement the provisions of this Clause 9 shall continue to apply for a period of three (3) years from the date hereof.

	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. 

  

 30 









	11.3	The Purchaser 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 Interests to
the Purchaser. 

  

	12	Taxation 

  

	12.1	The Seller confirms that it is registered and the Purchaser 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 Act 1994 in relation to the Interests.


  

	12.2	The Purchaser undertakes that it will use the 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 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 Purchaser 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. 

  

	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 Purchaser 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 Act 1994 for a direction that the records
relating to the Interests which under paragraph 6 of Schedule 11 to the Value Added Tax Act 1994 have been maintained by the Seller or its Affiliates should be preserved by the Seller or its Affiliates, as the case may be, 



  

 31 









	 	 
notwithstanding the provisions of the said section. The Seller shall, as soon as reasonably practicable following receipt thereof, provide the Purchaser with
a copy of any such direction and the Purchaser 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 Interests and the Seller
covenants to retain such records as required by paragraph 6 of Schedule 11 to the Value Added Tax Act 1994. 


  

	12.7	CT Adjustments 

  

	 	12.7.1	The Purchase Price shall be increased by the Purchaser 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 Purchaser 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 Purchaser 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. 

  

	 	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 Purchaser from the
Seller of the Seller’s estimate of such adjustments, the adjustments in dispute may be referred by either the Seller or the Purchaser 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 Purchaser. 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 Purchaser in equal shares
and the Parties shall bear their own costs in respect of such reference. 

  

 32 









	12.8	The Seller shall be liable for any liabilities arising under Schedule 15 to the Finance Act 1973 in respect of the Interests or the Licence(s)for periods ending up to the Economic
Date and the Purchaser shall be liable for all periods thereafter. 

  

	12.9.1	The Seller and the Purchaser 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 Purchaser 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 Purchaser, 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 Purchaser is reduced, the Seller shall pay to the Purchaser, by way of adjustment to the Purchase
Price, an amount equal to fifty percent (50%) of the amount by which the total of the Purchaser’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 Purchaser pursuant to this Clause 12.9.2 unless it shall have received from the Purchaser, as soon as practicable after the Purchaser becomes aware of the amount of capital
allowances not being so agreed, written notice containing reasonable details of the relevant claim including the Purchaser’s bona fide provisional estimate of the amount of the claim and in any event such notice is received on or before
31st March 2014. Any payment under this clause shall not be due for payment until the earlier of 1st 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.



  

	13	Variation 

 The terms and conditions of this Agreement shall only
be varied by an agreement in writing signed by each of the Parties and specifically referring to this Agreement. 
  

	14	Assignment 

 No Party shall assign or transfer its rights or its
obligations under this Agreement without the prior written consent of the other Party save that (a) prior to Completion the Purchaser may assign its rights under this Agreement (in whole or in part) with the consent of the Seller (such consent
not to be unreasonable withheld or delayed) and (b) after Completion the Purchaser may assign its rights under this Agreement (in whole or in part), in either case to an Affiliate(s) and/or to an Affiliate(s) of Edison S.p.A. 
  

 33 









	15	Rights of Third Parties 

 With the exception of the rights of the
Seller’s Affiliates to enforce the terms of Clause 6.6, nothing in this Agreement is intended to confer on any person any right to enforce any term of this Agreement which that person would not have had but for the Contracts (Rights of Third
Parties) Act 1999. Notwithstanding the foregoing, the Parties may by agreement rescind or vary any term of this Agreement without the consent of any of the Seller’s Affiliates. 
  

	16	General 

  

	16.1	If there is any conflict between the provisions of this Agreement and the provisions of the Assignment Documents, the provisions of this Agreement shall prevail. The provisions of
the main body of this Agreement shall prevail over the provisions of the Schedules in the event of any conflict. 

  

	16.2	Without prejudice to the provisions of Clauses 7.5 and 7.7, this Agreement shall remain in full force and effect notwithstanding Completion. 

  

	16.3	No waiver by any Party of any breach of a provision of this Agreement shall be binding unless made expressly and in writing and any such waiver shall relate only to the matter to
which it expressly relates and shall not apply to any subsequent or other matter. 

  

	16.4	This Agreement shall inure to the benefit of and be binding upon the respective successors and permitted assigns of the Parties. 

  

	16.5	This Agreement may be executed in any number of counterparts but shall not be effective until each Party has executed at least one counterpart. Each of the executed counterparts
shall be deemed to be an original of this Agreement, but taken together, all the counterparts shall constitute one and the same instrument. 

  

	16.6	This Agreement is not intended to constitute or create nor shall it be construed so as to constitute or create any partnership, association, joint venture or trust. Notwithstanding
the foregoing if, for the income tax purposes of the United States of America, this Agreement and the transactions under this Agreement are regarded as a partnership, each Party which is affected thereby elects to be excluded from the application of
all of the provisions of Subchapter “K” of Chapter 1 of Subtitle “A” of the Internal Revenue Code of 1986 as amended of the United States of America (the “Code”), as permitted and authorised by Section 761 of the
Code and the Treasury Regulations promulgated under the Code, and any future income tax laws of the United States containing similar provisions. No affected Party shall give any notices or take any other action inconsistent with the election made
hereby. In making the foregoing election, each affected Party states that the income derived by it from the transactions under this Agreement can be adequately determined without a computation of partnership taxable income. A Party that is not
subject to the income tax laws of the United States of America in respect of this Agreement and the transactions under this Agreement shall not be required to do any act or execute any instrument which might subject it to the taxation jurisdiction
of the United States of America. 

  

 34 









	16.7	Each provision of this Agreement is severable and distinct from the others and if any such provision shall in whole or in part be held to any extent to be illegal or unenforceable
under any enactment or rule of law that provision or part shall to that extent be deemed not to form part of this Agreement and the validity and enforceability of the remainder of this Agreement shall not be affected. 

  

	 16.8
	 This Agreement, and the confidentiality agreement between the Parties dated 30th May 2008 contain the entire agreement between the Parties and supersedes the Offer Letter dated 28 August 2008 from the Purchaser, the Letter Agreements dated
September 5, 2008 and September 11, 2008 between the Parties, all prior negotiations, proposals, statements of intent, understandings and agreements relating to the subject matter hereof. Each of the Parties agrees that it will have no
remedy in respect of any untrue representations or statements made by the other Party or its advisers, unless made fraudulently, and upon which it relied in entering this Agreement. 


  

	17	Governing Law and Arbitration 

  

	17.1	The construction validity and performance of this Agreement and all agreements executed pursuant hereto shall be governed by English law (other than choice of law rules).


  

	17.2	Subject to Clause 3.13 and Clause 12.7.4, all disputes arising out of or in connection with this Agreement shall be finally settled under the Rules of Arbitration of the LCIA by
three (3) arbitrators appointed in accordance with those rules. London shall be the seat of arbitration and the language of the arbitration shall be English and all documents submitted to the arbitration shall be submitted to the arbitration in
their original form together with an English translation. 

  

	17.5	Each Party agrees that without preventing any other mode of service, any document in any dispute referred to arbitration hereunder may be served on any Party by being delivered to
or left for that Party at its address for service of notices under Clause 10 and each Party undertakes to maintain such an address at all times in accordance with Clause 10 and to notify the other Party in advance of any change from time to time of
the details of such address in accordance with the manner prescribed for service of notices under Clause 10.
