1.2   INTERPRETATION

1.2.1 A reference in this Agreement or in any other document referred to herein
      or delivered in connection herewith to a statute or any provision thereof
      shall refer also to that statute or provision as amended or re-enacted.

1.2.2 A reference in this Agreement or in any other document referred to herein
      or delivered in connection herewith to an agreement or document shall
      refer also to such agreement or document as amended, varied or
      supplemented and shall include all appendices and other attachments.

2.    SHAREHOLDER LOANS

2.1   On the Effective Date the Lender shall provide the Borrower with a loan,
      subject to the terms of this Agreement. The amount of such loan shall be
      determined in accordance with the Debt Restructuring Agreement. Such loan
      amount shall constitute Subordinated Debt.

2.2   Any further indebtedness owed by the Borrower to the Lender shall also
      constitute Subordinated Debt, unless the parties agree otherwise (provided
      this is permissible pursuant to the terms of the Notes and the Indenture).
      Such further indebtedness shall be incurred as agreed between the parties.

2.3   Any distributions from Preem Petroleum to the Borrower by way of group
      contributions (Sw: KONCERNBIDRAG) which are made in the form of
      subordinated loans from the Borrower to Preem Petroleum under Clause 2.3
      of the Shareholder Loan Agreement No. 1B, shall be further distributed
      from the Borrower to the Lender as group contributions in the form of
      loans hereunder from the Lender to the Borrower, so that the amount of
      such loans shall constitute Subordinated Debt.

2.4   Nothing in this Agreement shall prevent the Borrower from incurring other
      debt owed to the Lender which is not Subordinated Debt (to the extent this
      is not prohibited under the terms of the Notes or the Indenture), from
      repaying such other debt or from paying interest on such other debt.

3.    REPAYMENT

      The Borrower shall not repay the Loan during the Subordination Period,
      except with the prior written consent of the Trustee.

                                                                            4(4)
--------------------------------------------------------------------------------

4.    INTEREST

4.1   Neither the Loan nor any other amount which may be payable hereunder shall
      carry interest before the date on which such amount is due and payable.

4.2   If the Borrower fails to pay an amount payable by it under this Agreement
      on the due date, it shall forthwith on demand by the Lender pay interest
      on the overdue amount from the due date up to the date of actual payment
      at a rate determined by adding a margin of two (2) percentage units to
      STIBOR on the due date. Interest shall be compounded at end of each thirty
      (30) day period during which the overdue amount remains outstanding.

5.    PAYMENTS

5.1   All payments by the Borrower under this Agreement shall be made for value
      on the due date (at such time as is customary for the settlement of
      transactions in the relevant currency) and in immediately available funds
      to the account at such office or bank as the Lender may designate from
      time to time. Any such designation shall be notified to the Borrower not
      later than five (5) Business Days before the payment is due.

5.2   All payments made by the Borrower under this Agreement shall be made
      without set-off or counterclaim.

5.3   If a payment is due on a day which is not a Business Day, the due date for
      that payment shall instead be the following Business Day.

5.4   A repayment or prepayment of the Loan is payable in Swedish Kronor.
      Amounts payable in respect of costs, expenses and Taxes and the like are
      payable in the currency in which they are incurred.

5.5   If Swedish Kronor is replaced as legal tender in Sweden by the euro, all
      references to Swedish Kronor in this Agreement shall be deemed to be
      references to the euro, provided that the Lender, acting reasonably and in
      good faith and after having consulted with the Borrower, shall determine
      at what time such replacement shall be made for the purpose of this
      Agreement in the event that such replacement includes a transition period.
      In case of any such change of currency, this Agreement shall be amended to
      the extent the Lender specifies to be necessary to reflect the change in
      currency and to put the Lender and the Borrowers in the same position, so
      far as possible, that they would have been in if no change of currency had
      occurred.

6.    WITHHOLDINGS

6.1   All payments to be made by the Borrower hereunder shall be made free and
      clear of any deduction or withholding.

6.2   If the Borrower is required by law to make any deduction or withholding on
      account of Tax or otherwise from any payment to the Lender hereunder, the
      sum due from it in respect of such payment shall be increased to the
      extent necessary to ensure that, after making of such deduction or
      withholding, the Lender receives a net sum equal to the sum which it would
      have received had no deduction or withholding been made.

6.3   This Clause 6 (Withholdings) shall not apply in the case of deductions or
      withholdings to be made with reference to income tax on its overall income
      ultimately due by the Lender by operation of applicable laws.

7.    INDEMNITIES

      If the Lender receives an amount in respect of the Borrower's liability
      under this Agreement or if that liability is converted into a claim,
      proof, judgement or order in a currency other than the currency in which
      such obligation is due (the "CONTRACTUAL CURRENCY"):

      (a)   the Borrower shall on demand indemnify the Lender as an independent
            obligation against any loss or liability arising out of or as a
            result of the conversion;

      (b)   if the amount received by the Lender, when converted into the
            Contractual Currency at a market rate in the usual course of its
            business, is less than the amount owed in the Contractual Currency,
            the Borrower shall on demand pay to the Lender an amount in the
            Contractual Currency equal to the deficit; and

      (c)   the Borrower shall on demand pay to the Lender any exchange costs
            and Taxes payable in connection with any such conversion.
