Other Events On June 22, 2004, Pioneer Natural Resources Company (the "Company") as the Borrower; JP Morgan Chase Bank as the Administrative Agent; JP Morgan Chase Bank and Bank of America, N.A., as the Issuing Banks; Wachovia Bank, National Association as the Syndication Agent; Bank of America, N.A., Bank One, N.A., Fleet National Bank and Wells Fargo Bank, National Association, as the Co-Documentation Agents; and certain other lenders entered into a First Amendment, dated as of June 9, 2004 (the "First Amendment"), to the Company's $700,000,000 5-Year Revolving Credit Agreement dated as of December 16, 2003 (the "Credit Agreement"). The First Amendment is attached hereto as Exhibit 99.1. The First Amendment changes certain definitions in the Credit Agreement, including a change to remove reference to Pioneer Natural Resources USA, Inc., a wholly-owned subsidiary of the Company ("Pioneer USA"), from the definition of "Subsidiary Guarantor" and adds definitions for "First Amendment" and "Total Adjusted Debt". As a result of the First Amendment, Pioneer USA is no longer a guarantor of the Credit Agreement. The indentures of the Company's senior notes provide for subsidiary guarantees of the Company's senior notes equivalent to the subsidiary guarantees imposed by the Credit Agreement as long as such guarantee was in existance. Accordingly, the First Amendment removes Pioneer USA as a guarantor of the Credit Agreement and has the effect of removing Pioneer USA as a guarantor of the Company's senior notes. Item 7.
