Notwithstanding the foregoing, if the date hereof is after the 30th day or 31st day, respectively, of any April or October and before the next succeeding April 15 or October 15, this Note shall bear interest from such April 15 or October 15, as the case may be; provided, however, that if the Company shall default in the payment of interest due on such April 15 or October 15, then this Note shall bear interest from the next preceding April 15 or October 15 to which interest on the Notes has been paid or duly provided for, or, if no interest has been paid on the Notes or duly provided for, from April 13, 1999. The interest so payable, and punctually paid or duly provided for, on any April 15 or October 15 will, except as provided in the Indenture dated as of April 13, 1999 (herein called the "Indenture"), duly executed and delivered by the Company, Union Pacific Resources Inc., an Alberta corporation, UPR Capital Company, a Nova Scotia unlimited liability company, and The Bank of New York, as Trustee (herein called the "Trustee"), be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the next preceding April 1 or October 1, as the case may be (herein called the "Regular Record Date"), whether or not a Business Day, and may, at the option of the Company, be paid by check mailed to the registered address of such Person. Any such interest which is payable, but is not so punctually paid or duly provided for, shall forthwith cease to be payable to the registered Holder on such Regular Record Date and may be paid either to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Notes not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed and upon such notice as may be required by such exchange, if such manner of payment shall be deemed practical by the Trustee, all as more fully provided in the Indenture. Notwithstanding the foregoing, in the case of interest payable at Stated Maturity, such 3 interest shall be paid to the same Person to whom the principal hereof is payable. The Bank of New York will be the Paying Agent and the Security Registrar with respect to the Notes. The Company reserves the right at any time to vary or terminate the appointment of any Paying Agent or Security Registrar, to appoint additional or other Paying Agents and other Security Registrars, which may include the Company, and to approve any change in the office through which any Paying Agent or Security Registrar acts; provided that there will at all times be a Paying Agent in The City of New York and there will be no more than one Security Registrar for the Notes. This Note is one of the duly authorized issue of debentures, notes, bonds or other evidences of indebtedness (hereinafter called the "Securities") of the Company, of the series hereinafter specified, all issued or to be issued under and pursuant to the Indenture, to which Indenture and any other indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee and any agent of the Trustee, any Paying Agent, the Company and the Holders of the Securities and the terms upon which the Securities are issued and are to be authenticated and delivered. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any), may be subject to different covenants and Events of Default and may otherwise vary as provided or permitted in the Indenture. This Note is one of the series of Securities of the Company issued pursuant to the Indenture and designated as the 7.30% Notes due April 15, 2009 (herein called the "Notes"), limited in aggregate principal amount to $200,000,000. The Notes will be redeemable as a whole or in part, at the option of the Company at any time, at a redemption price equal to the greater of (i) 100% of the principal amount to be redeemed and (ii) the sum of the present values of the Remaining Scheduled Payments (as 4 hereinafter defined) thereon, discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as hereinafter defined) plus 35 basis points, plus accrued interest on the principal amount being redeemed to the redemption date. "Treasury Rate" means, with respect to any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. "Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Notes to be redeemed that would be used, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes. "Independent Investment Banker" means one of the Reference Treasury Dealers appointed by the Trustee after consultation with the Company. "Comparable Treasury Price" means, with respect to any redemption date, (i) the arithmetic average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third business day preceding such redemption date, as published in the daily statistical release (or any successor release) by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S. Government Securities" or (ii) if such release (or any successor release) is not available or does not contain such prices on such business day, the arithmetic average of the Reference Treasury Dealer Quotations for such redemption date. "Reference Treasury Dealer" means Credit Suisse First Boston Corporation and its successors; provided, however, that if Credit Suisse First Boston shall cease to be a primary U.S. Government securities dealer in New York City (a "Primary Treasury Dealer"), the Company shall substitute therefor another Primary Treasury Dealer. 5 "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any redemption date, the arithmetic average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer by 5:00 p.m. on the third business day preceding such redemption date. "Remaining Scheduled Payments" means, with respect to any Note, the remaining scheduled payments of the principal thereof to be redeemed and interest thereon that would be due after the related redemption date but for such redemption; provided, however, that, if such redemption date is not an interest payment date with respect to such Security, the amount of the next succeeding scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to such redemption date. Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each holder of Notes to be redeemed. Unless the Company defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Notes or portions thereof called for redemption. If an Event of Default with respect to the Notes shall occur and be continuing, the principal of all of the Notes may be declared due and payable in the manner, with the effect and subject to the conditions provided in the Indenture. The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee to enter into supplemental indentures to the Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of each series under the Indenture with the consent of the Holders of not less than a majority in principal amount of the Securities at the time Outstanding of each series to be affected thereby on behalf of the Holders of all Securities of such series. The Indenture also permits the Holders of a majority in principal amount of the Securities at the time Outstanding of each series, on 6 behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults and their consequences with respect to such series under the Indenture. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note or such other Notes. No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the place, rate and respective times and in the coin or currency herein and in the Indenture prescribed. As provided in the Indenture and subject to the satisfaction of certain conditions therein set forth, including the deposit of certain trust funds in trust, the Company shall be deemed to have paid and discharged the entire indebtedness represented by, and the obligations under, the Securities of any series and to have satisfied all the obligations (with certain exceptions) under the Indenture relating to the Securities of such series. The Notes are issuable in registered form without coupons in denominations of $1,000 and any integral multiple of $1,000. Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations at the office or agency of the Company in the Borough of Manhattan, The City of New York, designated for such purpose and in the manner and subject to the limitations provided in the Indenture. Upon due presentment for registration of transfer of this Note at the office or agency of the Company in the Borough of Manhattan, The City of New York designated for such purpose, a new Note or Notes of authorized denominations for a like aggregate principal amount will be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture. No charge shall be made for any such transfer or exchange, but the Company may require payment of a sum 7 sufficient to cover any tax or other governmental charge imposed in connection therewith. The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. Unless otherwise defined herein, all terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture. This Note shall be construed in accordance with and governed by the laws of the State of New York. 8 Unless the certificate of authentication hereon has been manually executed by or on behalf of the Trustee under the Indenture, this Note shall not be entitled to any benefits under the Indenture, or be valid or obligatory for any purpose.
