                                  INTRODUCTION

      This Amendment No. 2 (this "Amendment") amends and supplements the Tender
Offer Statement on Schedule TO filed on March 28, 2007 and amended by Amendment
No. 1 filed April 5, 2007 (as so amended, the "Schedule TO") by Samson
Acquisition Corp. ("Purchaser"), a Maryland corporation and wholly-owned
subsidiary of Samson Investment Company, a Nevada corporation ("Parent"). The
Schedule TO relates to the offer by Purchaser to purchase all outstanding shares
of common stock, par value $0.001 per share, of PYR Energy Corporation, a
Maryland corporation (the "Company"), net per share in cash (subject to
applicable withholding taxes), without interest, upon the terms and subject to
the conditions set forth in the Offer to Purchase dated March 28, 2007, as
amended (the "Offer to Purchase"), and in the related Letter of Transmittal
which are annexed to and filed with the Schedule TO as Exhibits (a)(1) and
(a)(2), respectively. This Amendment is being filed on behalf of Purchaser and
Parent. Except as specifically provided herein, this Amendment does not modify
any of the information previously reported on the Schedule TO.

ITEM 5.  PAST CONTACTS, TRANSACTIONS, NEGOTIATIONS AND AGREEMENTS

      Item 5 of the Schedule TO is hereby amended and supplemented as follows:

      Section 10, "Background of the Offer; Contacts with the Company," of the
Offer to Purchase is amended and supplemented as follows:

      On March 31, 2007, Samson, the Company and their respective legal counsel
met at JAMS offices in Dallas, Texas for a court ordered mediation of the
lawsuit filed by the Company on July 29, 2005 in the U.S. District Court for the
Eastern District of Texas, Beaumont Division, against Lone Star and Samson
Resources Company. In attendance at the mediation on behalf of Samson were Mr.
Tholen, Mr. Viles, Mr. Daniel and Ms. Annabel Jones, internal Samson counsel,
Mr. Richard Watt, outside litigation counsel to Samson, and Mr. Scott Cohen,
outside corporate counsel to Samson, and on behalf of the Company were Mr.
Berry, Mr. Dennis M. Swenson, a Company director, and Mr. Robert Thibault and
Mr. Jesse R. Pierce, counsel to the Company. At the mediation, Samson renewed
its offer to the Company, which was first made at the February 21, 2007 meeting,
to purchase the Company's Jefferson County, Texas properties for aggregate
consideration consisting of $21 million in cash, plus the 3,689,200 shares of
Company common stock owned by Samson. The Company declined the offer.

      On April 6, 2007, Mr. Viles received a telephone call from Mr. Montano, of
C.K. Cooper, to notify Samson that the Company's board of directors would like
to meet with Samson to discuss an agreed upon transaction with Samson.

      On April 7 and April 8, 2007, Mr. Montano and Mr. Tholen spoke by
telephone several times to discuss arrangements for the meeting between Samson
and the Company on April 9, 2007.

      On April 9, 2007, Samson and the Company met at the offices of C.K. Cooper
in Irvine, California. Participating in the meeting on behalf of Samson were Mr.
Tholen, Mr. Viles, Mr. Koenig and Mr. Joe Lytle, Samson's senior geologist, and
on behalf of the Company were Mr. Kilpatrick, Mr. Rhodes and Mr. Swenson, Mr.
Berry and Mr. Montano. At this meeting, Samson and the Company reached an
agreement in principle pursuant to which Samson would make a revised tender
offer for all of the outstanding shares of Company common stock at a purchase
price of $1.30 per share in cash, subject to certain conditions, including the
negotiation and execution of a definitive merger agreement.

      On April 11, 2007, Samson and the Company issued a joint press release
announcing the agreement in principle.
