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 pence 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 pence 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.

	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 Act 1994 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 Act 1994 for a direction that the records relating to the
Option 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, 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 Act 1994.

  

	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 Act 1973 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 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. 

  

 43 

	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 Buyer 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 Buyer 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. 
  

	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. 

  

 44 

	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. 

  

	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 Buyer, 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 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.
