Any increase or decrease in interest rate resulting from a change in the Maximum Rate shall be effective immediately when such change becomes effective, without notice to the Borrower, unless Applicable Law (as defined in the Credit Agreement) requires that such increase or decrease not be effective until a later time, in which event such increase or decrease shall be effective at the earliest time permitted under the provisions of such law. Notwithstanding the foregoing, if during any period the Floating Rate exceeds the Maximum Rate, the rate of interest in effect on this Note shall be limited to the Maximum Rate during each such period, but at all times thereafter the rate of interest in effect on this Note shall be the Maximum Rate or, if there is no Maximum Rate, the Agreed Maximum Rate (as defined below), until the total amount of interest accrued on this Note equals the total amount of interest which would have accrued hereon if the Floating Rate had at all times been in effect. This Note is a revolving credit note and it is contemplated that by reason of prepayments hereon there may be times when no indebtedness is owing hereunder; but notwithstanding such occurrence, this Note shall remain valid and in full force and effect as to each principal advance made hereunder subsequent to each such occurrence. Each principal advance and each payment hereof made pursuant to this Note shall be reflected by the Bank's records and the aggregate unpaid amounts reflected by such records shall constitute rebuttably presumptive evidence of the principal and unpaid, accrued interest remaining outstanding on this Note. "Agreed Maximum Rate" means a per annum rate of seven and three-fourths percent (7.75%) plus the Floating Rate from time to time in effect, which Agreed Maximum Rate shall apply only during any period while there is no Maximum Rate applicable to this Note. Other capitalized terms used herein, that are not defined herein, shall have the meanings prescribed therefor in the Credit Agreement. The Borrower and the Bank hereby agree that Chapter 346 of the Texas Finance Code, shall not apply to this Note or the loan transaction evidenced by, and referenced in, the Credit Agreement (hereinafter defined) in any manner, including without limitation, to any account or arrangement evidenced or created by, or provided for in, this Note.

If any amount of interest taken or received by the Bank shall be in excess of the maximum amount of interest which, under Applicable Law, could lawfully have been collected on this Note, then the excess shall be deemed to have been the result of a mathematical error by the parties hereto and shall be refunded promptly to the Borrower. All amounts paid or agreed to be paid in connection with the indebtedness evidenced by this Note which would under Applicable Law be deemed "interest" shall, to the extent permitted by Applicable Law, be amortized, prorated, allocated and spread throughout the full term of this Note.

MDW ------------------- Borrower's Initials The Borrower and the Bank hereby agree that Chapter 346 of the Texas Finance Code, shall not apply to this Note or the loan transaction evidenced by, and referenced in, the Credit Agreement (hereinafter defined) in any manner, including without limitation, to any account or arrangement evidenced or created by, or provided for in, this Note. The principal sum of this Note, after giving credit for unadvanced principal, if any, remaining at final maturity, shall be due and payable on or before March 1, 2006; interest to accrue upon the principal sum from time to time owing and unpaid hereunder shall be due and payable as provided in the Credit Agreement; provided, however, the final installment of interest hereunder shall be due and payable not later than the maturity of the principal sum hereof, howsoever such maturity may be brought about. In no event shall the aggregate of the interest on this Note, plus any other amounts paid in connection with the loan evidenced by this Note which would under Applicable Law be deemed "interest," ever exceed the maximum amount of interest which, under Applicable Law, could be lawfully charged on this Note. The Bank and the Borrower specifically intend and agree to limit contractually the interest payable on this Note to not more than an amount determined at the Maximum Rate. Therefore, none of the terms of this Note or any other instruments pertaining to or securing this Note shall ever be construed to create a contract to pay interest at a rate in excess of the Maximum Rate, and neither the Borrower nor any other party liable herefor shall ever be liable for interest in excess of that determined at the Maximum Rate, and the provisions of this paragraph shall control over all provisions of this Note or of any other instruments pertaining to or securing this Note. If any amount of interest taken or received by the Bank shall be in excess of the maximum amount of interest which, under Applicable Law, could lawfully have been collected on this Note, then the excess shall be deemed to have been the result of a mathematical error by the parties hereto and shall be refunded promptly to the Borrower. All amounts paid or agreed to be paid in connection with the indebtedness evidenced by this Note which would under Applicable Law be deemed "interest" shall, to the extent permitted by Applicable Law, be amortized, prorated, allocated and spread throughout the full term of this Note. This Note is secured by all security agreements, collateral assignments, mortgages and lien instruments executed by the Borrower (or by any other party) in favor of Bank One, NA, as Administrative Agent for the Banks, including those executed simultaneously herewith, those executed heretofore and those hereafter executed, and including specifically and without limitation the Security Instruments described and defined in that certain Credit Agreement dated as of March 22, 2000 by and between Borrower, Ultra Petroleum (USA) Inc., and Bank One, Texas, National Association, as amended by that certain First Amendment to Credit Agreement dated as of July 19, 2001 by and between Borrower and Bank One, NA, and as amended and restated by that certain First Amended and Restated Credit Agreement dated March 1, 2002, as amended by the First Amendment thereto dated November 4, 2002 and the Second Amendment thereto dated May 14, 2003, by and among Borrower, Bank One, NA, as the Administrative Agent, as a Bank and as LC Issuer, and the several other banks and financial institutions who are from time to time party thereto as Banks (as may be further amended from time to time, the "Credit Agreement").
