2.5

Effect of Prepayments.  Any amounts prepaid under section 2.3 or 2.4 shall in each case be accompanied by payment of all accrued and unpaid interest on the principal amount being prepaid.

2.6

Payments.  The Borrower shall make each payment to be made hereunder, not later than 5:00 p.m. (local timein the jurisdiction where the Lenders account is maintained) in US Dollars on the day when due, in same day funds, by deposit of such funds to such account as the Lender shall stipulate. Whenever any payment hereunder is due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day.

2.7

Interest on Advances.  Interest shall accrue during each Interest Period on the unpaid principal amount of any Advance at a rate of six month LIBOR (as per Reuters page LIBOR 01) at the start of such Interest Period plus, up to and including the Repayment Date, three and one-half per cent (3.5%) per annum and, after the Repayment Date or from the date of any demand made during a Bankruptcy Event, five and one-half per cent (5.5%) per annum, in each case calculated on the daily amount outstanding on the basis of a 360-day year.

During the period up to and including the Final Economic Completion Date, accrued interest on the principal amount from time to time outstanding hereunder shall on each June 30 and December 31 be added to the principal outstanding, and thereafter shall accrue interest in like manner as other principal.

During the period following the Final Economic Completion Date, accrued interest on the principal amount from time to time outstanding hereunder shall be payable semi-annually in arrears from Available Funds on each June 30 and December 31, and any amount not so paid by virtue of a shortfall in Available Funds shall be added to the principal outstanding, and thereafter shall accrue interest in like manner as other principal.

2.8

Priority.  The Credit Facility shall rank behind and be subordinated in right of payment and security to the Project Debt Financing, the CAT Financial and all other leasing obligations, all hedging obligations and the Consortium Sub-Debt (but excluding, for greater certainty, any Other Shareholder Loans, as to which the Credit Facility shall rank senior).

The Lender shall enter into such subordination and other agreements, and take such further and other action, as may reasonably be required by the Borrower, or by any holder of indebtedness referred to above, in order to evidence and confirm  the  subordinated ranking of the  Credit Facility herein contemplated (which agreements will provide for, inter alia, customary notice of default and standstill provisions applicable to subordinated shareholder debt).

Security.
