Unless otherwise approved by the Lender, accrued interest is payable on the last business day of each calendar month, and on the date of each payment or prepayment of the Principal Amount. 1.5 The Lender will endorse from time to time and at such times as the Lender shall determine the following on Appendix I of this Agreement or any continuation thereof; (a) the outstanding Principal Amount; (b) the amount of any pre-payments of the outstanding Principal Amount made by the Borrower under Section 1.3 above; (c) the Lending Rate applying from time to time; (d) the amount of money transfers added to the outstanding Principal Amount pursuant to section 1.7 below; and (e) the amount of invoices sent added to the outstanding Principal Amount pursuant to section 1.8 below, PROVIDED that the failure so to endorse Appendix I shall not affect the Borrower's obligations hereunder. 1.6 Nothwithstanding anything to the contrary in this Agreement, Appendix I of this Agreement may be endorsed, amended and modified by the Lender without any consent from or writing executed by the Borrower. 1.7 Money transfers made from the Lender to the Borrower during the term of and pursuant to this Agreement shall be added to the outstanding Principal Amount on the value date that money transfers were made and interest shall accrue upon it as of that date. 1.8 At the Lender's option, amounts equal to the amounts of invoices sent from the Lender to the Borrower may be added to the outstanding Principal Amount on the last day of the month they 2 <Page> were sent and interest shall accrue upon it as of the first of the month following. 1.9 Subject to the terms and conditions of this Agreement, the Lender may make additional loans to the Borrower, following receipt by the Lender from the Borrower of a drawdown notice substantially in the form set out in Appendix II of this Agreement (the "DRAWDOWN NOTICE"), PROVIDED that the total amount of loans, (including loans made pursuant to a Drawdown Notice) money transfers and invoices sent added to the outstanding Principal Amount annually will not exceed the applicable annual funding requirement budget as determined by the Lender in its sole discretion. 1.10 All payments under this Agreement to the Lender will be made by the Borrower without reflecting any deduction for any set-off, suspension or counterclaim and without withholding or deduction for or on account of any present or future taxes, duties, assessments or governmental charges of whatever nature, unless the withholding of such taxes or duties is required by applicable law, in which case, the relevant payment shall be increased to the extent necessary to ensure that, after the making of such withholding or deduction, the Lender receives (and retains, free from any liability in respect of such deduction or withholding) a net sum equal to the sum that it would have received had no such withholding or deduction been required and the Borrower shall indemnify the Lender against any losses or costs incurred by any of them by reason of any failure of the Borrower to make any such deduction or withholding or by reason of any increased payment not being made on the due date for such payment. 2.
