PURPOSE OF AMENDMENT

      The purpose of this amendment is to amend and supplement Items 8 in the
Solicitation/Recommendation Statement on Schedule 14D-9 previously filed by PYR
Energy Corporation ("PYR Energy" or the "Company") on April 11, 2007, and
subsequently amended.


ITEM 8.    ADDITIONAL INFORMATION

Item 8 is hereby amended and supplemented by the addition of the following
information:

      Samson's Extension of the Subsequent Offering Period

      On June 4, 2007, Samson and Acquisition Corp. announced the extension of
the previously announced subsequent offering period to Tuesday, June 12, 2007 at
5:00 p.m., New York City time, unless extended. As of June 4, 2007, and
including those shares tendered in the initial offering period, approximately
27,481,752 shares of the Company Common Stock have been tendered, which,
together with the shares owned by Acquisition Corp. prior to the commencement of
the Offer, represents approximately 82 percent of the outstanding Company Common
Stock.

      Pursuant to the terms and conditions of the Merger Agreement, Acquisition
Corp. will be merged with and into the Company, and each outstanding share of
Company Common Stock not tendered into the Revised Offer, including in the
subsequent offering period (other than shares held by the Company, Samson,
Acquisition Corp. or stockholders who properly perfect appraisal rights under
Maryland law, if applicable), will be converted into the right to receive $1.30
per share in cash, without interest. Following consummation of the Merger, the
Company will continue as the surviving corporation and a wholly owned subsidiary
of Samson. Assuming Acquisition Corp. has acquired at least 90% of the
outstanding Company Common Stock following the expiration of the subsequent
offering period, the Merger is expected to occur promptly thereafter.

      Changes in Officers


      On May 30, 2007, the board of directors of the Company removed Mr. Kenneth
R. Berry, Jr. from the offices of President and Chief Executive Officer, Ms.
Jane M. Richards from the office of Chief Financial Officer and Mr. Tucker
Franciscus from the offices of Vice President-Strategic Development and
Secretary. Each of Messrs. Berry and Franciscus and Ms. Richards will remain
employed by the Company. Also on May 30, 2007, the board of directors of the
Company appointed Mr. C. Philip Tholen as Chief Executive Officer, President and
Chief Financial Officer, Mr. Scott Rowland as Vice President and Ms. Annabel
Jones as Secretary.
