          Item 1. Amended and Restated Description of Securities to be
Registered.

          On February 24, 2005, EOG Resources, Inc., a Delaware
corporation (the "Company"), entered into an amendment (the
"Amendment") to its Rights Agreement, dated as of February 14,
2000, as amended, between the Company and EquiServe Trust
Company, N.A. (as Rights Agent) (the "Rights Agreement") to
modify the definition of "Qualified Institutional Investor."
Under the terms of the Amendment, a Qualified Institutional
Investor is an institution that meets the following requirements:
(1) such institutional investor is described in Rule 13d-1(b)(1)
promulgated under the Securities Exchange Act of 1934 and is
eligible to report (and, if such institutional investor
beneficially owns greater than 5% of the Company's common stock,
par value $.01 per share (the "Company Common Stock"), then
outstanding, does in fact report) beneficial ownership of Company
Common Stock on Schedule 13G; (2) such institutional investor is
not required to file a Schedule 13D (or any successor or
comparable report) with respect to its beneficial ownership of
the Company Common Stock; (3) such institutional investor shall
"Beneficially Own" less than 15% of the Company Common Stock then
outstanding (including in such calculation the holdings of all of
such institutional investor's affiliates and associates other
than those which, under published interpretations of the SEC or
its Staff, are eligible to file separate reports on Schedule 13G
with respect to their beneficial ownership of the Company Common
Stock); and (4) such institutional investor shall Beneficially
Own less than 20% of the Company Common Stock then outstanding
(including in such calculation the holdings of all of the
institutional investor's affiliates and associates).  Under the
terms of the Rights Agreement, a "Person" (other than the
Company, any subsidiary of the Company, any employee benefit plan
of the Company or any subsidiary of the Company, or any entity
holding Company Common Stock for or pursuant to the terms of any
such plan) who does not meet the aforementioned exception is
deemed an "Acquiring Person" if such Person is the Beneficial
Owner of 10% or more of the Company Common Stock.

          The foregoing description is qualified in its entirety
by reference to the Rights Agreement and the Amendment which are
incorporated herein by reference.
