1 EXHIBIT 10.8 NOTE October 10, 2000 US$32,515,200 SECTION 1. AMOUNT; INTEREST; PAYMENTS; DEFAULT. Western Australia Gas Transmission Company I, a Cayman Islands corporation, (together with its successors and permitted assigns, "Borrower"), for value received, hereby promises to pay to CMS Oil and Gas (International) Ltd., a Cayman Islands corporation ("Holder"), the principal amount of Thirty-two Million Five Hundred Fifteen Thousand Two Hundred United States Dollars (US$32,515,200). Such payment shall be made on January 8, 2001 (the "Maturity Date"). The Borrower further agrees to pay, in lawful money of the United States of America ("Dollars") and in immediately available funds, interest from the date hereof on the unpaid and outstanding principal amount hereof until such unpaid and outstanding principal amount shall become due and payable (whether at the Maturity Date, by acceleration or otherwise) in arrears on the Maturity Date at a rate per annum equal to 6.44% (the "Borrowing Rate"). All accruals of interest shall be calculated on the basis of a 360-day year and the actual number of days elapsed, including the date on which each payment of interest is made. If any amounts required to be paid by the Borrower under this Note remain unpaid at the Maturity Date, interest shall accrue on the aggregate outstanding balance of such unpaid amount from the Maturity Date until those amounts are paid in full at a rate per annum equal to the Borrowing Rate plus 200 basis points (2%). The Borrower has the right to prepay the principal and interest, or a portion thereof, without penalty, at any time prior to the Maturity Date. The Borrower may, on any date (the "Prepayment Date") on no less than one (1) Business Day's (as defined hereinafter) prior written notice (each a "Prepayment Notice"), prepay all or any portion of the then outstanding principal balance of the Note specified in such Prepayment Notice, by paying to the Holder on such date the principal amount specified in such Prepayment Notice, together with all accrued but unpaid interest on such principal amount so prepaid on and as of the date of such prepayment. Any amount prepaid may not be reborrowed hereunder. On the Maturity Date, the Borrower shall pay or cause to be paid to the Holder the aggregate outstanding principal amount of the Note, all accrued but unpaid interest thereon and all other amounts then due under this Note. All payments on or in respect of this Note shall be made by wire transfer of immediately available funds, with the Federal Reference number relating to such transfer received by Holder no later than 12:00 p.m. New York time, to such account as may be specified in writing by Holder from time to time. If any payment cannot be made via wire transfer, such payment shall be made by check (drawn off a U.S. bank branch) made payable to CMS Oil and Gas (International) Ltd., Fairlane Plaza South, 330 Town Center Drive, Suite 1100, Dearborn Michigan, 48126, USA. Any payment Page 1 of 6 2 or prepayment received by the Holder after 12:00 noon New York time, shall be deemed to have been received on the next succeeding Business Day. If any payment on this Note becomes due and payable on a date that is not a Business Day, "Business Day" being a day that is not a Saturday, Sunday or legal holiday in the State of Michigan, the Cayman Islands, or Western Australia, or a day on which banking institutions chartered by the State of Michigan, the Cayman Islands, or Australia are legally required or authorized to close, such payment shall be made on the first succeeding Business Day. All payments under this Note shall be applied, to the extent of the amount thereof, first, to any costs, charges or expenses then due and payable by the Borrower to the Holder hereunder, second, to the amount of accrued but unpaid interest on the Note as of the date of such payment or with respect to any prepayment, to the amount of all accrued but unpaid interest on the principal amount so prepaid, and third, against the outstanding principal balance of the Note as of the date of such payment. All payments or prepayments under this Note shall not be subject to set-off or counterclaim of any kind for any amounts which may be due or alleged to be due from the Holder to the Borrower. If any of the following events (each an "Event of Default") shall occur and be continuing after the applicable grace period and notice requirement (if any), the Holder shall be entitled to exercise the remedies set forth herein: (a) the Borrower shall fail to make payment when due and payable of any amount that the Borrower is obligated to pay under this Note; (b) (i) the Borrower shall generally not pay its debts as such debts become due, or shall admit in writing its inability to pay its debts generally, or shall make an assignment for the benefit of creditors; or (ii) any proceeding shall be instituted by or against the Borrower seeking to adjudicate it as bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief, or composition of its debts under any law relating to bankruptcy, insolvency, or reorganization or relief of debtors, or seeking the entry of an order for relief or the appointment of a receiver, trustee, or other similar official for it or for any substantial part of its property and, in the case of a proceeding instituted against the Borrower, either such proceeding shall remain undismissed or unstayed for a period of 60 days or any of the actions sought in such proceeding (including, without limitation, the entry of an order for relief against the Borrower or the appointment of a receiver, trustee, custodian or other similar official for the Borrower or any of its property) shall occur; or (iii) the Borrower shall take any corporate or other action to authorize any of the actions set forth above in this subsection (b); or (c) one or more judgments, decrees or orders for the payment of money in excess of $5 Million in the aggregate shall be rendered against the Borrower or its properties and either (i) enforcement proceedings shall have been commenced by any creditor upon any such judgment or Page 2 of 6 3 order or (ii) there shall be any period of 30 consecutive days during which a stay of enforcement of such judgment or order, by reason of a pending appeal or otherwise, shall not be in effect; or (d) any material provision of this Note, after execution hereof shall for any reason other than the express terms hereof cease to be valid and binding on any party hereto; or the Borrower, or any court or governmental regulatory body having jurisdiction over the Borrower, shall so assert in writing; or (e) any government or governmental authority shall have condemned, nationalized seized, or otherwise expropriated all or any substantial part of the property or other assets of the Borrower or of its capital stock or shall have assumed custody or control of such property or other assets or of the business or operations of the Borrower or of its capital stock or shall have taken any action for the dissolution, receivership or disestablishment of the Borrower or any action that would prevent the Borrower or its officers from carrying on its business or operations or a substantial part thereof; or (f) any material adverse change in the financial condition or business of the Borrower shall occur, which, in the reasonable opinion of the Holder, may imperil, delay, or prevent the fulfillment by the Borrower of any of its obligations under this Note.
