      corporate documents, and this Agreement has been duly executed and
      delivered and is a valid, binding and enforceable obligation of it.

      figures set out in APPENDIX 3 (three page document) which shows the

      70,230,523 and special tax purposes of NOK 73,065,139 as at 31 December
      2003, as well as remaining tax depreciation basis of NOK 27,861,424,
      unused uplift of NOK 1,851,192 and future unused uplift of NOK 8,358,427
      as at the same date (together referred to as the "Tax Balances") of the
      Company.

      In the event that the Tax Balances are reduced when the actual figures are
      determined by the Oil Taxation Board in an assessment of the Company, the
      Seller shall repay to the Buyer as a reduction of the Purchase Price 75.88
      % of the reduction in the Tax Balances multiplied with the relevant tax
      rate applicable as of 31 December 2003. In the event that the Tax Balances
      are higher when the actual figures are determined by the Oil Taxation
      Board in an assessment of the Company, the Buyer shall pay to the Seller
      75.88 % of such surplus in the Tax Balances multiplied with the relevant
      tax rate applicable as of 31 December 2003.

      The Seller's payment under this section 7.5 shall take place within 7
      Business Days after the Buyer has notified the Seller that the Tax
      Balances are finally determined by the Oil Taxation Board. The Buyer's
      payment under this section 7.5 shall take place within 7 Business Days
      after the Tax Balances are finally determined by the Oil Taxation Board.

      In the event that the Tax Balances are reduced when the actual figures are
      determined by the Oil Taxation Board in an assessment of the Company, the
      Buyer shall undertake that the Company will make claim against Aker
      Maritime Finance AS to the extent the

                                      7/11


      Company is entitled to do so according to the agreement dated 7 November
      2003 between Aker Maritime Finance AS and the Company. 75.88 % of any
      payment made by Aker Maritime Finance AS according to that agreement shall
      immediately be forwarded to the Seller. If the Company fails to recover
      funds due to its failure to comply with the terms of that agreement, the
      Buyer shall immediately pay to the Seller 75.88 % of the amount that Aker
      Maritime Finance AS would have been obliged to pay to the Company
      according to that agreement, less 75.88 % of the costs the Company has
      incurred for recovery of such amount.

      The Buyer shall use its reasonable endeavours to dispute any reduction in
      the Tax Balances through appeals on the assessment. The Buyer shall
      provide the Seller with copies of all of the Company's tax assessments
      (and material correspondence relating to changes in the Tax Balances) for
      tax periods up to 31 December 2003, within a reasonable time given the
      circumstances. To the extent that it is within its powers as a shareholder
      in the Company, the Buyer shall ensure that the Company does not make any
      amendment to its tax returns for the years 2002 and 2003, if the effect of
      such amendment is to increase the Seller's liability or decrease the
      Seller's entitlements, as the case may be, under this section 7.5, without
      the Seller's prior written approval, unless such amendment is required by
      law, is necessitated by previously made factual errors or is initiated by
      the tax authorities.

      Any right to adjust the Purchase Price under this section with respect to
      the Tax Balances shall lapse following the expiry of the statutory
      limitation of amendments of tax assessments for the Company.
