Entry into a Material Definitive Agreement On September 30, 2005, Pioneer Natural Resources Company (the "Company"), as Borrower, JPMorgan Chase Bank, N.A. as Administrative Agent, and a syndication of participating banks (collectively with JPMorgan Chase Bank, N.A, the "Lenders") entered into an Amended and Restated 5-Year Revolving Credit Agreement (the "Amended Credit Agreement") that amended and restated the Company's 5-Year Revolving Credit Agreement dated as of December 16, 2003. The Amended Credit Agreement matures in September 2010, or such later date as maturity with respect to the loan commitments of consenting Lenders shall be extended (not to exceed three one-year extensions) in accordance with the terms of the Amended Credit Agreement. The terms of the Amended Credit Agreement provide for initial aggregate loan commitments of $1.5 billion, which may be increased to a maximum aggregate amount of $1.8 billion if the Lenders increase their loan commitments or if loan commitments of new financial institutions are added to the Amended Credit Agreement. Borrowings under the Amended Credit Agreement may be in the form of revolving loans or swing line loans. Aggregate outstanding swing line loans may not exceed $100 million. Revolving loans bear interest, at the option of the Company, based on (a) a rate per annum equal to the higher of the prime rate announced from time to time by JPMorgan Chase Bank or the weighted average of the rates on overnight Federal funds transactions with members of the Federal Reserve System during the last preceding business day plus 0.5 percent or (b) a base Eurodollar rate, substantially equal to the London Interbank Offered Rate ("LIBOR"), plus a margin (the "Applicable Margin") that is determined by reference to a grid based on the Company's debt rating (currently .625 percent). Swing line loans bear interest at a rate per annum equal to the "ASK" rate for Federal funds periodically published by the Dow Jones Market Service plus the Applicable Margin. The Company pays commitment fees on the undrawn amounts under the Amended Credit Agreement that are determined by reference to a grid based on the Company's debt rating, which commitment fees were 0.125 percent per annum at September 30, 2005. As of September 30, 2005, the Company had $755.0 million borrowed under the Amended Credit Agreement, bearing interest at an effective rate of 4.75 percent per annum. Many of the parties to the Amended Credit Agreement are also counterparties to the Company's derivative instruments and provide other banking, investment banking and brokerage services to the Company in the ordinary course of their businesses. The Amended Credit Agreement contains certain financial covenants, which include the maintenance of a ratio of the Company's earnings before gain or loss on the disposition of assets, interest expense, income taxes, depreciation, depletion and amortization expense, exploration and abandonments expense and other noncash charges and expenses to consolidated interest expense of at least 3.5 to 1.0; maintenance of a ratio of total debt to book capitalization less intangible assets (other than intangible oil and gas assets), accumulated other comprehensive income and certain noncash asset write-downs not to exceed 0.60 to 1.0; and if the Company should fall below an investment grade rating by both Moody's Investors Service and Standard and Poor's prior to the date, if any, on which its investment grade rating by either of such rating agencies is determined to be stable under the terms of the Amended Credit Agreement, maintenance of an annual ratio of the net present value of the Company's oil and gas properties to total debt of at least 1.50 to 1.0 for the first 18 months following the date of the Amended Credit Agreement, and 1.75 to 1.0 thereafter. The terms of the Amended Credit Agreement provide for customary representations and warranties, negative and affirmative covenants (in addition to the financial covenants described above) and events of default. The lenders may declare any outstanding obligations under the Amended Credit Agreement immediately due and payable upon the occurrence, and during the continuance of, an event of default, which includes a defined change in control of the Company. As of September 30, 2005, the Company had $35.3 million of undrawn letters of credit under the Amended Credit Agreement, subject to a per annum fee of 0.75 percent. As of September 30, 2005, the Company had unused borrowing capacity of $709.7 million under the Amended Credit Agreement. The Company was a borrower under its 364-Day Credit Agreement dated as of September 28, 2004, which agreement was scheduled to mature on September 27, 2005. To accommodate the timing of the execution of the Amended Credit Agreement, the Company and its lenders converted the outstanding loans under the 364-Day Credit Agreement to term loans and extended the maturity of such loans by up to fifteen business days. In connection with the funding of the Amended Credit Agreement on September 30, 2005, all amounts outstanding under the 364-Day Credit Agreement were retired and the 364-Day Credit Agreement terminated. 3 PIONEER NATURAL RESOURCES COMPANY The Amended Credit Agreement is attached as exhibit 99.1, and the terms and conditions thereof are incorporated herein by reference.
