(2) Commencing June 1, 1996, and on the first day of each calendar month thereafter through and including May 1, 2000 (the "Full Amortization Date"), the unpaid principal balance of this Note, plus accrued interest thereon, shall be due and payable in 48 consecutive monthly installments. Beginning with the June 1, 1996 installment and continuing to and including the installment due on the first Change Date (as hereinafter defined), the monthly installments shall be in an amount which would be sufficient to repay in full the original principal balance hereof, together with interest at the Applicable Rate, in 48 substantially equal monthly payments (i.e., the payments shall be set based on a 48-month amortization). If the rate of interest is adjusted on any Change Date, the amount of the monthly installments of principal and interest will change, effective with the first monthly installment due after the Change Date. Changes in the monthly installments will be made such that the monthly installments will always be sufficient to repay the unpaid balance as of the applicable Change Date in full on the Full Amortization Date, at the new rate of interest, in substantially equal installments. Any amount due hereunder remaining unpaid as of the Full Amortized Date shall be due and payable on the Full Amortization Date. The "Applicable Rate," as herein used, shall be a variable rate of interest, and shall initially be equal to the WSJ Prime Rate (as hereinafter defined) published on the original date of this Note. The Applicable Rate shall be adjusted on each Change Date to the WSJ Prime Rate published on such Change Date. In the event a Change Date occurs on a day that the WSJ (as hereinafter defined) is not published, the Applicable Rate shall be adjusted to the WSJ Prime -1- Rate published in the most recent previously published edition of the WSJ. The Applicable Rate in effect at any given time shall remain in effect without change until the next Change Date. The "Change Dates," as herein used, shall be the first day of August, 1996, and the first day of each November, February, May and August thereafter during the term hereof. The "WSJ Prime Rate," as herein used, means that annual rate of interest from time to time published in the daily issues of The Wall Street Journal (the "WSJ") as the Prime Rate under the column presently headed "Money Rates" as that base rate of interest for corporate loans currently being charged by certain of the largest commercial banks in the United States of America. If the WSJ should cease to publish an annual rate of interest as the Prime Rate, the WSJ Prime Rate for purposes of this Note shall be that variable annual rate of interest readily ascertainable from reported or published sources established by others independent of the holder hereof which the holder hereof shall in good faith determine to be the principal equivalent of that rate of interest formerly published in the WSJ as the Prime Rate. Each of the payments referred to above shall be applied first to the payment of interest then accrued and due on the unpaid principal balance evidenced by this Note and the remainder thereof shall be applied to the reduction of the principal balance. The undersigned may voluntarily prepay all or a portion of the principal indebtedness hereunder, at any time, without premium or penalty. If any payment shall become due upon a Saturday or Sunday or other day on which a majority of commercial banks in Des Moines, Iowa, are closed by reason of a holiday, such payment shall be due upon the next ensuing banking day. All sums not paid when due hereunder shall bear interest from the due date until paid at the WSJ Prime Rate plus six percent (6%) per annum. If all or any portion of the indebtedness hereby evidenced is not paid when due, and such failure to pay continues for a period in excess of ten days following notice by the holder to the undersigned of such failure to pay, or in the event of the dissolution, insolvency, bankruptcy or receivership of the undersigned, the holder may, without further notice or demand, declare this indebtedness to be immediately due and payable. The undersigned agrees that if, and as often as, this Note is placed in the hands of an attorney for collection or to defend or enforce any of the holder's rights hereunder or under any instruments securing payment of this Note, the undersigned will pay to the holder its reasonable attorney's fees and all court costs and other expenses incurred in connection therewith. The makers, endorsers, sureties, guarantors and all other persons who may become liable for all or any part of this obligation severally waive presentment for payment, protest and notice of nonpayment. Said parties consent to any extension of time (whether one or more) of payment hereof, release of all or any part of the security for the payment hereof and the release of any -2- party liable for payment of this obligation. Any such extension of time or release may be made at any time and from time to time without notice to any such party and without discharging said party's liability hereunder. This Note is to be construed according to the laws of the State of Iowa. INTERCOAST GLOBAL MANAGEMENT, INC.

The Subject Wells.
