Exhibit 10.21 PROMISSORY NOTE US$130 million November 10, 1998 PDVSA Finance Ltd. ("PDVSA Finance"), for value received, hereby unconditionally promises to pay to the order of PDV America, Inc., or to its assigns (the "Lender"), in lawful money of the United States of America, the principal amount of One Hundred Thirty Million Dollars (US$130 million) (the "Loan") in installments as described below. PDVSA Finance further promises to pay interest on the unpaid principal amount of the Loan at the interest rate and on the dates described below. 1. General 1.1. General PDVSA Finance covenants and agrees that, so long as any amount payable under the Loan remains unpaid it shall observe and perform each of the covenants and obligations set forth in Article 4 and Article 7 of the Fiscal and Paying Agency Agreement, (the "Fiscal Agency Agreement"), dated May 14, 1998, among PDVSA Finance and The Chase Manhattan Bank, as Fiscal Agent, and Chase Manhattan Bank Luxembourg S.A., as Paying Agent, which Articles are incorporated by reference in this promissory note as if fully set forth herein, in accordance with their terms. Capitalized terms used in this promissory note have the meanings specified in the Fiscal Agency Agreement unless otherwise defined herein. This promissory note constitutes a Debt Agreement as defined in the Fiscal Agency Agreement. 2. Definitions 2.1. Definitions. For purposes of this Note, the following terms shall have the meanings indicated: "Business Day" means a day that in the city in which Loan amounts are payable, is not a day on which banking institutions are authorized or required by law or regulation to close. "Dollars" or "$" means the lawful currency of the United States of America. "Loan" means the loan to PDVSA Finance evidenced hereby. "Make-Whole Premium" means a premium determined as of the Business Day prior to the prepayment date for a prepayment being made pursuant to Section 3.2 of this promissory note, in respect of the outstanding Loan amount (or the portion thereof) to be prepaid, equal to the amount (but not less than zero) obtained by subtracting (a) the sum of the unpaid principal amount of such Loan (or the portion thereof) being prepaid and the amount of interest thereon accrued to such prepayment date, from (b) the Current Value of the amount of principal and interest on such Loan (or the portion thereof) being prepaid that would otherwise have become due on and after the date of such determination if the Note were not being prepaid (each such amount of principal or interest being referred to herein as an "Amount Payable"). The "Current Value" means such Amount Payable discounted (on a monthly basis) to its present value on the date of determination, in accordance with the following formula: Amount Payable Current Value = --------------------- (1+d/12)n where "d" is the sum of (i) 50 basis points, plus (ii) the Treasury Yield per annum expressed as a decimal, and "n" is an exponent (which need not be an integer) equal to the number of monthly periods and portions thereof (any such portion of a period to be determined by dividing the number of days in such portion of such period by the total number of days in such period, both computed on the basis of twelve 30-day months in a 360-day year) between the date of such determination and the due date of the Amount Payable. The "Treasury Yield" shall be determined by reference to the yields for U.S. Treasury Notes as indicated (currently on page "500" thereof) on the Telerate Screen for actively traded U.S. Treasury Notes at approximately 10:00 a.m. (New York City time) on the Business Day next preceding such prepayment date or, if such yields shall not be reported as of such time or the yields reported as of such time shall not be ascertainable, by reference to the most recent Federal Reserve Statistical Release H.15 (519) which has become publicly available at least two Business Days prior to such prepayment date, and shall be the most recent weekly average yield on actively traded U.S. Treasury Notes adjusted to a constant maturity equal to the then remaining weighted average life of the outstanding principal amount of the Note (the "Remaining Life"), computed by dividing (A) the sum of all remaining principal payments into (B) the total of the products obtained by multiplying (1) the amount of each remaining principal payment by (2) the number of years (calculated to the nearest one-twelfth) which will elapse between the date as of which such computation is made and the due date of each remaining principal payment. If the Remaining Life is not equal to the constant maturity of a U.S. Treasury Note for which a weekly average yield is given, the Treasury Yield shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of (x) the actively traded U.S. Treasury Note with the average life closest to and greater than the Remaining Life and (y) the actively traded U.S. Treasury Note with the average life closest to and less than the Remaining Life, except that if the Remaining Life is less than one year, the weekly average yield on actively traded U.S. Treasury Notes adjusted to a constant maturity of one year shall be used. The Treasury Yield shall be computed to the fifth decimal place (one-thousandth of a percentage point) and then rounded to the fourth decimal place (one-hundredth of a percentage point). "Next Payment of Scheduled Debt Service" means on any date of determination for any Debt Agreement, the amount of the first payment of Scheduled Debt Service in respect of Indebtedness outstanding under such Debt Agreement that is scheduled to be paid in cash after such date of determination. For this purpose, amounts scheduled to be paid on the same date shall be treated as a single payment whether such amounts shall be principal, interest or otherwise. "Note" means this promissory note of PDVSA Finance evidencing the payment obligations of PDVSA Finance in respect of the Loan. 2 "Payment Date" means each February 10, May 10, August 10 and November 10 of each year. If a Payment Date falls on any day which is not a Business Day, such Payment Date will be postponed to the next day which is a Business Day. 3 "Taxes" has the meaning assigned to that term in Section 6.1 below. 3. Repayment 3.1. Repayment. (a) PDVSA Finance shall repay the outstanding principal amount of the Loan commencing on February 10, 2009, in 20 equal quarterly installments of principal as illustrated in Exhibit A. (b) In the event of any prepayment pursuant to Section 3.2 hereof, the remaining unpaid installments of principal of the Loan will be ratably reduced by an aggregate amount equal to the principal amount so being repaid. 3.2. Optional Prepayment. PDVSA Finance may prepay the Loan, at any time, in whole or in part, in an integral multiple of $1,000,000 at the Prepayment Price as provided in this Section 3.2. The Prepayment Price shall be an amount equal to 100% of the outstanding principal amount to be prepaid together with accrued and unpaid interest thereon together with an amount equal to the Make-Whole Premium, if any, calculated as of the Business Day prior to the prepayment date. PDVSA Finance shall no later than the third Business Day preceding the date it designates for any prepayment, give the Lender written notice of the amount to be prepaid on such date. Any notice so given will be irrevocable. 4. Interest 4.1. Rate. Interest shall be payable in arrears quarterly on each Payment Date commencing on February 10, 1999 as illustrated in Exhibit A. Except as otherwise expressly provided in Section 4.2, interest shall accrue on the outstanding principal amount of the Loan, at a rate per annum equal to 8.558 percent (8.558%). 4.2. Interest on Late Payments. If PDVSA Finance shall fail to pay when due any installment of principal of or interest on the Note, it shall pay the Lender on demand interest on the amount in default (after giving effect to any applicable grace period) from the date such payment became due until payment in full at the rate of 1% over the applicable per annum interest rate. 5. Payments; Computations 5.1. Making of Payments. Each payment by PDVSA Finance to the Lender under this Note shall be made in Dollars pursuant to the terms of Section 3.02 of the Fiscal Agency Agreement or, if the Fiscal Agency Agreement shall no longer be in effect, pursuant to such other instructions as the Lender may give by prior written notice to PDVSA Finance. 5.2. Computations. Accrued interest on the Loan shall be calculated on the basis of a 360-day year of twelve 30-day months and shall be payable quarterly in arrears on each Payment Date. 4 6. Taxes 6.1. Taxes. All payments by PDVSA Finance hereunder shall be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings imposed by the Cayman Islands or Venezuela or any political subdivision or taxing authority therein (all such taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes"). If any Taxes shall be required by law to be deducted from or in respect of any amount payable hereunder, (i) the amount payable by PDVSA Finance shall be increased as may be necessary so that after making all required deductions the Lender shall receive an amount equal to the sum it would have received had no such deductions been made, (ii) PDVSA Finance shall make such deductions and (iii) PDVSA Finance shall pay the full amount deducted to the relevant taxing authority in accordance with applicable law. Within 30 days after the date of any payment of Taxes by PDVSA Finance in respect of any payment hereunder, PDVSA Finance will furnish to the Lender the original or a certified copy of a receipt evidencing payment thereof. 7.
