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

          On June 15, 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" and
to amend the Rights Agreement in certain other respects.  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; and (3) such institutional investor
shall "Beneficially Own" less than 15% of the Company Common
Stock then outstanding; provided, however, that a Person who
would constitute a Qualified Institutional Investor except for
its failure to satisfy clause (3) above shall nonetheless
constitute a Qualified Institutional Investor if (A) such Person
or an Affiliate of such Person shall have, as of December 31,
2004, reported beneficial ownership of greater than 5% of the
Company Common Stock for a period of two consecutive years and
shall thereafter continuously beneficially own greater than 5% of
the Company Common Stock then outstanding prior to the time of
determination, (B) such Person shall be the Beneficial Owner of
less than 15% of the Company Common Stock then outstanding
(including in such calculation the holdings of all such Person'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 (C) such Person shall
be the Beneficial Owner of less than 30% of the Company Common
Stock then outstanding (including in such calculation the
holdings of all such Person'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.
