Page 2 EXPLANATORY NOTES: This Amendment No. 1 to Schedule 13D (this "Amendment") is being filed by Samson Investment Company ("Samson") identified in the Schedule 13D filed on January 4, 2007 (the "Schedule 13D") with the Securities and Exchange Commission (the "SEC") relating to the common stock, par value $0.001 per share, of Pyr Energy Corporation (the "Issuer"). The Schedule 13D is hereby amended and supplemented by Samson as set forth below in this Amendment. Capitalized terms used but not defined in this Amendment shall have the meanings given in the Schedule 13D. Item 3. Source and Amount of Funds or Other Consideration The disclosure in Item 3 is hereby amended and restated in its entirety as follows: The aggregate amount of funds used by Samson to purchase the 3,689,200 shares of the Issuer's common stock beneficially owned by it (the "Shares") was approximately $3.6 million, including commissions. The funds used to purchase the Shares were obtained from Samson's working capital. Any funds used to purchase the Issuer's common stock in the future will also be obtained from Samson's working capital. Item 4. Purpose of Transaction The disclosure in Item 4 is hereby amended and restated in its entirety as follows: Samson's initial acquisitions of the Issuer's common stock were effected for investment purposes. In connection with its most recent acquisition of shares of the Issuer's common stock, however, Samson began evaluating whether to make an offer to acquire the Issuer or a material portion of its oil and gas properties. Samson has changed its investment intent and now proposes to acquire all of the outstanding common stock of the Issuer. On January 29, 2007, Samson sent a letter to the Issuer, a copy of which is incorporated by reference into Item 4 and included as Exhibit A to this Amendment, pursuant to which Samson notified the Issuer of its proposal to offer to purchase 100% of the outstanding common stock of the Issuer at a cash price of $1.23 per share in accordance with the terms of the letter. As stated above in Item 3, the full purchase price for the shares of the Issuer's common stock will be funded from working capital and no additional financing will be required. Samson reserves the right to be in contact with members of the Issuer's management, the members of the Issuer's board of directors, other significant shareholders and others regarding alternatives that Issuer could employ to maximize shareholder value. Samson may, and reserves the right to, acquire additional shares of the Issuer's common stock at any time and from time to time in the open market, in privately negotiated transactions or otherwise. In addition, Samson may determine to dispose of all or any portion of the Shares at any time or from time to time in the open market, in privately negotiated transactions or otherwise. Further, Samson reserves the right to act in concert with any other shareholders of the Issuer, or other persons, for a common purpose should they determine to do so, and/or to recommend courses of action to the Issuer's management, the Issuer's board of directors and the shareholders of the Issuer. Page 3 Except as referenced above, neither Samson, nor to the best knowledge of Samson, any of the persons named on Schedule A of the Schedule 13D, has any plans or proposals of the types referred to in clauses (b) through (j) of Item 4 of Schedule 13D.
