(c) Seller will not be required to meet any claim under clause 12.1(a) or 12.1(b) to the extent that: (i) the Taxation would not have arisen, or would have been reduced or eliminated but for a failure by the Company after the Completion Date to make a claim or election or to give any notice or consent, the making or giving of which was notified by Seller in writing to Buyer five Business Days prior to the Execution Date, or where the making or giving of which will not adversely affect the Company is notified by Seller in writing to Buyer ten Business Days prior to the date the claim or election or notice of consent was required to be made or given; 26 (ii) Buyer or the Company will receive or has received a reduction in Tax payable after the Completion Date in relation to the matters giving rise to the claim, however only the net present value to the Company or Buyer of the reduction in Tax payable as at the date the Tax giving rise to the claim is payable shall be taken into account; (iii) the Taxation relates to an amount of income or an asset that was not taken into account in the calculation of the Purchase Price where the benefit of the income or asset arising after the Effective Date is equal to or in excess of the amount of the claim; (iv) any relief available to the Company in relation to a period ended on or before 31 December 2001 which has not been taken into account in the calculation of the Purchase Price and which is able to relieve or mitigate that Taxation liability; (v) it is for any Tax loss or memorandum account balance of the Company which is eliminated as a result of the transfer of Shares pursuant to this Agreement; (vi) the Company or Buyer, without the written consent of Seller has made a payment (except to the extent required by law) or admission of liability in respect of a Taxation claim or has taken other steps (including failing to notify Seller) which may in any way prejudice any objection to it or defence to that Taxation claim; (vii) the Company, without the written consent of Seller after the Completion Date amends or requests an amendment to any return filed prior to Completion by the Company with the Inland Revenue Department or other relevant revenue authority, other than an amendment required by law. (d) Any payment Seller is required to make in relation to any claim under this clause 12.1: (i) subject to clause 12.1(d)(ii), must be made at least 3 Business Days before the date on which the Taxation in respect of which the payment is required to be made is due for payment; (ii) where the amount of Taxation is payable immediately, is to be paid to Buyer on demand being made by Buyer; and (iii) is to be made to Buyer in reduction and refund of the Purchase Price. Provided however that in any case Seller may satisfy a claim for an income tax liability by way of offsetting tax losses of Seller or its Affiliates with the net income of the Company to the extent the requirements of the Tax Act are satisfied. (e) Buyer may not make a claim under this clause 12.1 after the sooner of the following: (i) the date after which the Inland Revenue Department or other relevant public body is no longer able to issue an assessment or similar notice in respect of the period or event giving rise to the claim; and (ii) 8 years after the Execution Date. 27 (f) Seller shall have the right to control all aspects of any Taxation claim giving rise to a claim under clause 12.1, including whether and how a Taxation claim is disputed and the appointment of counsel provided that Seller shall consult with the Company in respect of the decisions made by Seller and will take into account all reasonable concerns and issues raised by Buyer in all action that is taken by Seller following consultation. (g) For the purposes of any claim by Buyer under this clause 12.1, Taxation will be deemed to be suffered or incurred by or arise in respect of Buyer to the extent that Taxation is suffered or incurred by the Company. It will not be necessary for Buyer to establish loss or damage to itself whether by way of diminution of the Shares or otherwise, and the amount of the Taxation suffered or incurred by or arising in respect of Buyer will be deemed to be equal to the Taxation suffered or incurred by the Company. (h) Seller's aggregate liability under clause 12.1 is limited to the net overall increased liability for Taxation incurred by the Company in respect of the period prior to and including 31 December 2001 (not taking into account non-income tax amounts in relation to the period from the Execution Date). 12.2 Refunds Buyer acknowledges that the Company may be entitled to receive refunds of Taxes for operations before the Execution Date or in respect of supplies made pursuant to the EENZL Agreement or Southern Petroleum (Ohanga) Share Sale Agreement and that to the extent that these refunds have not been taken into account pursuant to Clause 12.1(c) that these refunds are for the benefit of Seller and agrees to co-operate and procure the Company to co-operate with Seller to obtain the refunds and reimburse refunds obtained to Seller forthwith upon receipt by Buyer or the Company. 12.3 Gross Up (a) If Seller is required by New Zealand law to make any deduction or withholding from any sum payable by it to Buyer under clause 8.1 or 12.1; or (b) Buyer is required by New Zealand law to characterise any amount received or receivable from Seller under clause 8.1 or 12.1 other than as an adjustment to the Purchase Price and is required by New Zealand law to make any payment of income tax in the income year of receipt on or in relation to such amount; then the sum payable by Seller will be increased to the extent necessary to ensure that after Seller has made the deduction, withholding or payment, or Buyer has paid the income tax, Buyer receives and retains (free of any liability for any such deduction, withholding or payment) a net sum equal to the sum that Buyer would have received and so retained had no such deduction, withholding or payment been made. 12.4 Refund of Gross Up Where any additional amount is payable by Seller under clause 12.3, Buyer shall refund to Seller any payment made under that clause 12.3 to the extent Buyer itself obtains a refund, set-off, deduction or credit in respect of any deduction, withholding or payment referred to in clause 12.3 and the refund by Buyer shall be made within 5 Business days of the date on 28 which Buyer receives the benefit of that refund, set-off, deduction or credit in respect of the deduction, withholding or payment. 12.5 Limitation on Claims In the event that Buyer is entitled to make a claim under clause 8.1 for a breach by Seller of the warranties given under clause 9.1, and when any such act, failure or omission by Seller giving rise to Buyer's claim, simultaneously or consequently amounts to a breach of Seller's indemnity under clause 12.1, then rather than being entitled to make further or additional claim against Seller, Buyer shall be entitled to make claim against Seller under either clause 8.1 or clause 12.1, but not both, and any such claim made by Buyer shall constitute Buyer's entire claim against Seller in terms of such breach. 13 CONFIDENTIALITY AND ANNOUNCEMENTS 13.1 Agreed Announcements Subject to Clause 13.2, no Party shall, without the written consent of the other Party, issue or make any public announcement or statement regarding this Agreement. 13.2 Legal Requirements (a) If a Party is required to issue or make an announcement or statement in respect of this Agreement in order to comply with: (i) applicable law; or (ii) the requirements of any recognised stock exchange on which the securities of a Party or any of its Affiliates are listed; then the Parties shall agree on the form and substance of such announcement or statement and a copy of the same shall be furnished to the other Party prior to publication or release.
