                  AMERICAN EXPLORATION COMPANY, a corporation organized and
existing under the laws of the State of Delaware (the "Corporation"), pursuant

Company.

                  SECOND: The Restated Certificate of Incorporation of the
Corporation is hereby amended by deleting the first paragraph of Article Fourth
thereof and substituting therefor the following:

                  "FOURTH: The total number of shares of all classes of stock
which the Corporation shall have authority to issue is 50,100,000 shares, of
which 100,000 shares, par value $1.00 per share, shall be a class designated
"Preferred Stock" and 50,000,000 shares, par value $.05 per share, shall be a
class designated "Common Stock." Each outstanding share of Common Stock as of
the Effective Date (as hereinafter defined) shall be converted into and
reconstituted as one-tenth of a share of Common Stock. No fractional shares
shall be issued upon such conversion and reconstitution, and the number of
shares of Common Stock to be issued shall be rounded down to the nearest whole
share. If a fractional interest in a share of Common Stock would, except for the
provisions of the preceding sentence, be deliverable upon such conversion and
reconstitution, the Corporation shall pay an amount in cash equal to the fair
market value of such fractional interest, as determined by the Corporation's
Board of Directors, to each holder of shares of Common Stock to whom such
fractional interest would have been deliverable. As used in this Article FOURTH,
"Effective Date" shall mean the date on which the Certificate of Amendment to
the Restated Certificate of Incorporation of the Corporation is filed with the
Secretary of State of the State of Delaware to affect the inclusion of this
paragraph."

                  THIRD: That the amendment to the Restated Certificate of
Incorporation set forth in this Certificate of Amendment has been duly adopted
in accordance with Section 242 of the General Corporation Law of the State of
Delaware by affirmative vote of a majority of the members of the Board of
Directors of the Corporation and by the affirmative vote of holders entitled to
cast a majority of the votes entitled to be cast by the outstanding shares of
the Corporation's Common Stock and the outstanding shares of the Corporation's
$450 Cumulative Convertible Preferred Stock, Series C, voting as a single class,
and the affirmative vote of a majority of the votes entitled to be cast by the
holders of outstanding shares of the Corporation's Common Stock, voting
separately as a class.

seal to be hereunto affixed and this Certificate of Amendment to be executed by
John M. Hogan, its Senior Vice President, and by T. Frank Murphy, its Secretary,
