(i) if within a further 6 months of the date of such grant (or, in any event, if by the date which is 12 months from the Completion Date) no exploration licence over the balance of the block (currently the subject of Petroleum Licence 3599) is granted, or is granted to someone other than the Company or any of its Affiliates then, the Buyer shall have not received the full benefit for which it paid the Purchase Price, and shall be entitled to present the Zorlu Holding cheque referred to in clause 4.3(b) and draw-down (in full) the amount of US$18,000,000; and

Page 14

(ii) if after the draw-down amount in sub-paragraph (i) above is paid to the Buyer an exploration licence for the balance of the block (the subject of Petroleum Licence 3599) is granted to the Company or any of its Affiliates then the Buyer shall promptly pay to the Seller (or Zorlu Holding) the sum of US$18,000,000.

6.5 Covenants for gas connections following Completion

The Buyer and the Seller agree and acknowledge that:

(a) US$20,000,000 will be dedicated and set aside by the Seller towards the construction from time to time (at the cost of the Seller) of natural gas transmission lines and facilities required to transport gas produced from the Petroleum Licences from the outlet of the compression station(s) to be established by the Buyer to the inlet of the “local distribution company” or to a BOTAŞ pipeline connection where that is the applicable point of sale;

(b) the parties will enter into gas connection protocols in accordance with the principles set out in the Gas Connection Agreement referred to at clause 1.5(d) from time to time under which the Seller must construct natural gas transmission lines and facilities required to transport gas produced from each of the Petroleum Licences, at the cost of the Seller (using funds including those set aside under clause 6.5(a));

(c) in the Alpullu gas field located in Petroleum Licence 3599, the Company has established a producing field which has no nearby market to take the gas. The Seller, in co-ordination with the Buyer, commits to immediately commence planning and proceed with construction of a connection (transmission) line from the Alpullu field to the BOTAŞ transmission network (a distance of approximately 22 kilometres) or such other location as the Parties may agree upon, as further set forth in the Gas Connection Agreement. This connection line shall be constructed by or on behalf of the Seller under its commitment under this clause 6.5 and the cost of such connection line shall be financed out of the funds set aside under clause 6.5(a);

(d) the parties will endeavour to coordinate well drilling, gas gathering and compression systems and gas transmission lines to ensure that all xxxxx capable of production are within the time frames described in the Framework Agreement, the Gas Connection Agreement and the Gas Storage Agreement (referred to in clause 1.5) connected and producing at their maximum efficiency rate;

(f) as to the connection line referred to in clause 6.5(c) and other future connection lines to the BOTAŞ transmission network, the Gas Connection Agreement is to contain a mechanism allowing the Seller to recover some of its unrecovered costs of constructing and commissioning those connection lines.

6.6 Accounting for Loss of Licences

(a) The parties agree that the Purchase Price was determined on the basis that the Buyer would (by acquiring the Company and, in turn, Petrogas) receive the benefit of all of

Amity Oil Share Purchase Agreement

Page 15

the Petroleum Licences including the Alpullu production lease referred to in clause 6.4. The Company is obliged to comply with a variety of obligations in relation to the Petroleum Licences. If, for any reason other than by voluntary relinquishment by the Buyer or any of the affiliates and subsidiaries of the Buyer, any of the Petroleum Licences are terminated (or the Alpullu production lease (the subject of block 3599 referred to in clause 6.4) is not awarded) through no fault or liability of the Buyer either prior to Completion or within 6 months of the Completion Date, there shall be an adjustment to the Purchase Price in favour of the Buyer. The Parties shall use their best efforts to procure the award of the Alpullu production lease and Petroleum Licence no. 3599 (referred to in clause 6.4) to the Company and/or any of its Affiliates. If the Alpullu production lease or Petroleum Licence no. 3599 is not awarded to the Company and/or to one of its Affiliate, the Company shall take all necessary legal steps provided for in the Turkish Petroleum Law to secure the award of such licence or lease, at the Seller’s cost (where such costs shall be verified).

(b) If the parties cannot agree on an appropriate adjustment to the Purchase Price within 20 Business Days of request in writing from either party, then either party may refer the matter to the Technical Expert for a determination with a request that the Technical Expert makes a decision on the disagreement as soon as practical after receiving any submissions form the Buyer and Seller. Those submissions must be made in writing within 30 days after the Technical Expert is appointed and a copy must be made available to each party. In respect of the Technical Expert:

(i) the decision of the Technical Expert is, in the absence of manifest error, conclusive and binding on the parties for the purposes of determining the amount of the adjustment (if any) to the Purchase Price;

(ii) the Seller and Buyer agree to each pay one half of the Technical Expert’s costs and expenses in connection with the reference;

(iii) the Technical Expert will be appointed as an expert and not an arbitrator.

(iv) the procedures for determination are to be determined by the Technical Expert in its discretion.

If the Purchase Price is adjusted pursuant to clause 6.6 after Completion, then the Seller must within 5 Business Days of the determination of the adjustment amount (by agreement or determination by the Technical Expert) refund to the Buyer the amount of the adjustment, by electronic transfer of cleared funds (in $US) to a bank account nominated by the Buyer to the Seller in writing. If the adjustment relates to a Petroleum Licence held (or formerly held) by Petrogas, the Seller agrees that it shall be liable to pay the entire amount of the adjustment notwithstanding that it was not the holder (as at the date of this agreement) of the Minority Petrogas Shares.

(c) (Financial clean-out) As soon as practicable following the date of execution of this agreement, and by no later than the Completion Date, the Seller must use its best endeavours (including procuring performance by the Company, Petrogas, other members of the Zorlu Group and third parties) to ensure that (to the extent reasonably practicable):

(i) all revenues and income derived before the Effective Date and all receivables that were outstanding at the Effective Date have been collected by the Company or Petrogas;

Such amounts (determined in accordance with paragraphs (i) to (vi) above, and having regard to the guiding principles set out in clause 6.7(a)) shall be aggregated (and set-off against each other, to the extent relevant) to determine a positive or negative total amount.

(e) The Buyer will provide the Seller with a copy of the Statement within 5 Business Days of it being finalised. The Seller shall consult with the Buyer and advise whether it agrees with the contents of the Statement. If the Seller does not raise any objection to the content of the Statement within 10 Business Days of receipt, then the Statement shall be taken to be agreed for the purposes of this agreement.
