These two agreements are called the Stock Rights and Restrictions Agreement and the Registration Rights Agreement. On July 15, 1999, Devon executed an agreement (the "Termination Agreement") with Kerr-McGee. The Termination Agreement provides for, among other things, the termination of the Stock Rights and Restriction Agreement upon the effectiveness of the pending merger of Devon Energy Corporation and PennzEnergy Company. A copy of the Termination Agreement is filed herewith as exhibit 4. Item 7. Financial Statements and Exhibits (c) Exhibits 4.

Upon the effectiveness of the Merger, the Registration Agreement is hereby amended to delete Section 5 thereof entitled "Stock Rights and Restrictions Agreement" and, as so amended, shall continue in force and effect in accordance with its terms. 6.
