Item 1.   Description of Registrant's Securities to be Registered.

     Reference is hereby made to the Form 8-A of Vintage Petroleum, Inc. (the
"Corporation"), filed with the Securities and Exchange Commission on March 22,
1999, and such Form 8-A is incorporated herein by reference.

     On April 3, 2002, the Corporation executed the First Amendment (the
"Amendment") to the Rights Agreement dated as of March 16, 1999 (the "Rights

terms used herein and not otherwise defined shall have the meanings ascribed to
them in the Rights Agreement, as amended by the Amendment.

things, amends the Rights Agreement to lower the threshold at which a person

incorporated herein by reference. The foregoing discussion does not purport to
be complete and is qualified in its entirety by reference to such exhibit.
