REVISED LETTER OF TRANSMITTAL

THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT MIDNIGHT, NEW YORK CITY

TIME, ON THURSDAY, MAY 24, 2007, UNLESS THE OFFER IS EXTENDED.

DELIVERY OF THIS LETTER OF TRANSMITTAL TO AN ADDRESS, OR TRANSMISSION OF INSTRUCTIONS VIA A FACSIMILE NUMBER, OTHER THAN AS SET FORTH ABOVE, WILL NOT CONSTITUTE A VALID DELIVERY.

THE INSTRUCTIONS ACCOMPANYING THIS LETTER OF TRANSMITTAL SHOULD BE READ CAREFULLY AND IN THEIR ENTIRETY BEFORE THIS LETTER OF TRANSMITTAL IS COMPLETED.

This Letter of Transmittal is to be completed by stockholders of PYR Energy Corporation either if certificates evidencing Shares (as defined below) are to be forwarded herewith or if delivery of Shares is to be made by book-entry transfer to an account maintained by the Depositary at the Book-Entry Transfer Facility (as defined in and pursuant to the procedures set forth in Section 3 of the Offer to Purchase). DELIVERY OF DOCUMENTS TO A BOOK-ENTRY TRANSFER FACILITY DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.

Stockholders whose certificates evidencing Shares (“Share Certificates”) are not immediately available or who cannot deliver their Share Certificates and all other documents required hereby to the Depositary prior to the Expiration Date (as defined in Section 1 of the Offer to Purchase) or who cannot complete the procedure for delivery by book-entry transfer on a timely basis and who wish to tender their Shares must do so pursuant to the guaranteed delivery procedure described in Section 3 of the Offer to Purchase. See Instruction 2.

This Letter of Transmittal supersedes and replaces, in its entirety, the previously circulated Letter of Transmittal sent to stockholders on or about March 28, 2007. Tendering stockholders may continue to use the previously circulated Letter of Transmittal or they may use this Letter of Transmittal. Stockholders using the previously circulated Letter of Transmittal to tender their Shares will be deemed to be tendering pursuant to the Offer and will receive the offer price of $1.30 per Share as described in the Offer to Purchase and the Supplement if Shares are accepted for payment and paid for by the Purchaser (as defined below) pursuant to the Offer. Stockholdes tendering their Shares according to the guaranteed delivery procedures set forth in Section 3 of the Offer to Purchase may do so using either the previously circulated Notice of Guaranteed Delivery sent to stockholders on or about March 28, 2007 or the Notice of Guaranteed Delivery circulated herewith. Unless otherwise indicated, as used herein, the term “Notice of Guaranteed Delivery” refers to any such document.

Shares previously tendered pursuant to the Offer to Purchase, dated March 28, 2007, and the related Letter of Transmittal and not withdrawn constitute valid tenders for purposes of the Offer. Stockholders who have validly tendered and not withdrawn their Shares are not required to take any further action with respect to such Shares in order to receive the offer price of $1.30 per Share if Shares are accepted for payment and paid for by the Purchaser pursuant to the Offer, except as may be required by the guaranteed delivery procedure if such procedure was utilized. See Section 3 of the Offer to Purchase. If you have not already tendered your Shares, please disregard the materials prevously delivered to you and use the materials accompanying the Supplement.

The undersigned hereby tenders to Samson Acquisition Corp., a Maryland corporation (“Purchaser”) and a wholly owned subsidiary of Samson Investment Company, a privately owned Nevada corporation (“Parent”), the above-described shares of common stock, par value $0.001 per share (the “Common Stock”), of PYR Energy Corporation, a Maryland corporation (the “Company”), and the associated Series A Junior Participating Preferred Stock purchase rights (the “Rights,” and together with the Common Stock, the “Shares”) issued pursuant to the Rights Agreement, dated as of January 31, 2007, between the Company and U.S. Stock Transfer Corporation, as Rights Agent, for $1.30 per Share, net to the seller 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 or supplemented from time to time, the “Offer to Purchase”), the Supplement to the Offer to Purchase, dated April 30, 2007 (the “Supplement”), receipt of which is hereby acknowledged, and in this Letter of Transmittal (as may be amended or supplemented form time to time, the “Letter of Transmittal”, which, together with the Offer to Purchase and the Supplement collectively constitute the “Offer”). The undersigned understands that Purchaser reserves the right to transfer or assign, in whole or from time to time in part, to one or more of its affiliates the right to purchase all or any portion of Shares tendered pursuant to the Offer.

Upon the terms and subject to the conditions of the Offer (and if the Offer is extended or amended, the terms of any such extension or amendment), and subject to, and effective upon, acceptance for payment of Shares tendered herewith, in accordance with the terms of the Offer, the undersigned hereby sells, assigns and transfers to or upon the order of Purchaser all right, title and interest in and to all Shares that are being tendered hereby and all dividends, distributions (including, without limitation, distributions of additional Shares) and rights declared, paid or distributed in respect of such Shares on or after the date of the Offer to Purchase (collectively, “Distributions”) and irrevocably appoints the Depositary the true and lawful agent and attorney-in-fact of the undersigned with respect to such Shares (and all Distributions), with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to (i) deliver Share Certificates evidencing such Shares (and all Distributions), or transfer ownership of such Shares (and all Distributions) on the account books maintained by the Book-Entry Transfer Facility, together, in either case, with all accompanying evidences of transfer and authenticity, to or upon the order of Purchaser, (ii) present such Shares (and all Distributions) for transfer on the books of the Company and (iii) receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares (and all Distributions), all in accordance with the terms of the Offer.

By executing this Letter of Transmittal, the undersigned hereby irrevocably appoints C. Philip Tholen, Dudley Viles, Annabel Jones and Mike Daniel, and each of them, as the attorneys and proxies of the undersigned, each with full power of substitution, to vote in such manner as each such attorney and proxy or his substitute shall, in his sole discretion, deem proper and otherwise act (by written consent or otherwise) with respect to all Shares tendered hereby which have been accepted for payment by Purchaser prior to the time of such vote or other action and all Shares and other securities issued in Distributions in respect of such Shares, which the undersigned is entitled to vote at any meeting of stockholders of the Company (whether annual or special and whether or not an adjourned or postponed meeting) or consent in lieu of any such meeting or otherwise. This proxy and power of attorney is coupled with an interest in Shares tendered hereby, is irrevocable and is granted in consideration of, and is effective upon, the acceptance for payment of such Shares by Purchaser in accordance with other terms of the Offer. Such acceptance for payment shall revoke all other proxies and powers of attorney granted by the undersigned at any time with respect to such Shares (and all Shares and other securities issued in Distributions in respect of such Shares), and no subsequent proxies, powers of attorney, consents or revocations may be given by the undersigned with respect thereto (and if given will not be deemed effective). The undersigned understands that, in order for Shares or Distributions to be deemed validly tendered,

immediately upon Purchaser’s acceptance of such Shares for payment, Purchaser must be able to exercise full voting and other rights with respect to such Shares (and any and all Distributions), including, without limitation, voting at any meeting of the Company’s stockholders then scheduled.

The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer Shares tendered hereby and all Distributions, that when such Shares are accepted for payment by Purchaser, Purchaser will acquire good, marketable and unencumbered title thereto and to all Distributions, free and clear of all liens, restrictions, charges and encumbrances, and that none of such Shares and Distributions will be subject to any adverse claim. The undersigned, upon request, shall execute and deliver all additional documents deemed by the Depositary or Purchaser to be necessary or desirable to complete the sale, assignment and transfer of Shares tendered hereby and all Distributions. In addition, the undersigned shall remit and transfer promptly to the Depositary for the account of Purchaser all Distributions in respect of Shares tendered hereby, accompanied by appropriate documentation of transfer, and pending such remittance and transfer or appropriate assurance thereof, Purchaser shall be entitled to all rights and privileges as owner of each such Distribution and may withhold the entire purchase price of Shares tendered hereby, or deduct from such purchase price, the amount or value of such Distribution as determined by Purchaser in its sole discretion.

No authority herein conferred or agreed to be conferred shall be affected by, and all such authority shall survive, the death or incapacity of the undersigned. All obligations of the undersigned hereunder shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned. Except as stated in the Offer to Purchase, this tender is irrevocable.

The undersigned understands that the valid tender of Shares pursuant to any one of the procedures described in Section 3 of the Offer to Purchase and in the Instructions hereto will constitute the undersigned’s acceptance of the terms and conditions of the Offer. Purchaser’s acceptance of such Shares for payment will constitute a binding agreement between the undersigned and Purchaser upon the terms and subject to the conditions of the Offer (and, if the Offer is extended or amended, the terms or conditions of any such extension or amendment).

Unless otherwise indicated below in the box entitled “Special Payment Instructions”, please issue the check for the purchase price of all Shares purchased and return all Share Certificates evidencing Shares not tendered or not accepted for payment in the name(s) of the registered holder(s) appearing above under “Description of Shares Tendered”. Similarly, unless otherwise indicated below in the box entitled “Special Delivery Instructions”, please mail the check for the purchase price of all Shares purchased and return all Share Certificates evidencing Shares not tendered or not accepted for payment (and accompanying documents, as appropriate) to the address(es) of the registered holder(s) appearing above under “Description of Shares Tendered” on the reverse hereof. In the event that the boxes below entitled “Special Payment Instructions” and “Special Delivery Instructions” are both completed, please issue the check for the purchase price of all Shares purchased and return all Share Certificates evidencing Shares not tendered or not accepted for payment in the name(s) of, and deliver such check and return such Share Certificates (and any accompanying documents, as appropriate) to, the person(s) so indicated. Unless otherwise indicated below in the box entitled “Special Payment Instructions”, please credit any Shares tendered hereby and delivered by book-entry transfer that are not accepted for payment by crediting the account at the Book-Entry Transfer Facility designated above. The undersigned recognizes that Purchaser has no obligation, pursuant to the Special Payment Instructions, to transfer any Shares from the name of the registered holder(s) thereof if Purchaser does not accept for payment any Shares tendered hereby.

Share Certificates evidencing all physically tendered Shares, or a confirmation of a book-entry transfer into the Depositary’s account at the Book-Entry Transfer Facility of all Shares delivered by book-entry transfer, as well as a properly completed and duly executed Letter of Transmittal (or a manually signed facsimile thereof) and any other documents required by this Letter of Transmittal, must be received by the Depositary at one of its addresses set forth below prior to the Expiration Date (as defined in Section 1 of the Offer to Purchase) or the expiration of a subsequent offering period, if applicable. If Share Certificates are forwarded to the Depositary in multiple deliveries, a properly completed and duly executed Letter of Transmittal must accompany each such delivery.

IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

No alternative, conditional or contingent tenders will be accepted and no fractional Shares will be purchased. By execution of this Letter of Transmittal (or a manually signed facsimile hereof), all tendering stockholders waive any right to receive any notice of the acceptance of their Shares for payment.

If the space provided on the reverse hereof under “Description of Shares Tendered” is inadequate, the Share Certificate numbers, the number of Shares evidenced by such Share Certificates and the number of Shares tendered should be listed on a separate signed schedule and attached hereto.

4. Partial Tenders (not applicable to stockholders who tender by book-entry transfer). If fewer than all Shares evidenced by any Share Certificate delivered to the Depositary herewith are to be tendered hereby, fill in the number of Shares that are to be tendered in the box entitled “Number of Shares Tendered”. In such cases, new Share Certificate(s) evidencing the remainder of Shares that were evidenced by the Share Certificates delivered to the Depositary herewith will be sent to the person(s) signing this Letter of Transmittal, unless otherwise provided in the box entitled “Special Delivery Instructions” on the reverse hereof, as soon as practicable after the Expiration Date or the termination of the Offer.

If this Letter of Transmittal is signed by the registered holder(s) of Shares tendered hereby, the signature(s) must correspond with the name(s) as written on the face of the Share Certificates evidencing such Shares without alteration, enlargement or any other change whatsoever.

If any Shares tendered hereby are held of record by two or more persons, all such persons must sign this Letter of Transmittal.

If any Shares tendered hereby are registered in different names, it will be necessary to complete, sign and submit as many separate Letters of Transmittal as there are different registrations of such Shares.

If this Letter of Transmittal is signed by the registered holder(s) of Shares tendered hereby, no endorsements of Share Certificates or separate stock powers are required, unless payment is to be made to, or Share Certificates evidencing Shares not tendered or not accepted for payment are to be issued in the name of, a person other than the registered holder(s). If the Letter of Transmittal is signed by a person other than the registered holder(s) of the Share Certificate(s) evidencing Shares tendered, the Share Certificate(s) tendered hereby must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name(s) of the registered holder(s) appear(s) on such Share Certificate(s).

6. Stock Transfer Taxes. Except as otherwise provided in this Instruction 6, Purchaser will pay all stock transfer taxes with respect to the sale and transfer of any Shares to it or its order pursuant to the Offer. If, however, payment of the purchase price of any Shares purchased is to be made to, or Share Certificate(s) evidencing Shares not tendered or not accepted for payment are to be issued in the name of, any person other than the registered holder(s) or if tendered certificates are registered in the name of any person other than the person(s) signing the Letter of Transmittal, the amount of any stock transfer taxes (whether imposed on the registered holder(s), or such other person, or otherwise) payable on account of the transfer to such other person will be deducted from the purchase price of such Shares purchased, unless evidence satisfactory to Purchaser of the payment of such taxes, or exemption therefrom, is submitted.

EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR TRANSFER TAX STAMPS TO BE AFFIXED TO THE SHARE CERTIFICATES EVIDENCING SHARES TENDERED HEREBY.

7. Special Payment and Delivery Instructions. If a check for the purchase price of any Shares tendered hereby is to be issued in the name of, and/or Share Certificate(s) evidencing Shares not tendered or not accepted for payment are to be issued in the name of and/or returned to, a person other than the person(s) signing this Letter of Transmittal or if such check or any such Share Certificate is to be sent to a person other than the signor of this Letter of Transmittal or to the person(s) signing this Letter of Transmittal but at an address other than that shown in the box entitled “Description of Shares Tendered” on the reverse hereof, the appropriate boxes herein must be completed.

8. Questions and Requests for Assistance or Additional Copies. Questions or requests for assistance may be directed to the Information Agent at its address and telephone numbers as set forth on the back page of this Letter of Transmittal. Requests for additional copies of the Offer to Purchase, the Supplement, this Letter of Transmittal, the Notice of Guaranteed Delivery and the Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 may be directed to the Information Agent, and copies will be furnished promptly at Purchaser’s expense. Stockholders may also contact their brokers, dealers, commercial banks, trust companies or other nominees for assistance concerning the Offer.

9. Substitute Form W-9. Each tendering stockholder is required to provide the Depositary with a correct Taxpayer Identification Number (“TIN”) on the Substitute Form W-9 which is provided under “Important Tax Information” below, and to certify, under penalty of perjury, that such number is correct and that such stockholder is not subject to backup withholding of U.S. federal income tax and that such stockholder is a U.S. person. If a tendering stockholder has been notified by the Internal Revenue Service that such stockholder is subject to backup withholding, such stockholder must cross out item (2) of the Certification box of the Substitute Form W-9, unless such stockholder has since been notified by the Internal Revenue Service that such stockholder is no longer subject to backup withholding. Failure to provide the information on the Substitute Form W-9 may subject the tendering stockholder to backup withholding of U.S. federal income tax at a 28% rate on the payment of the purchase price of all Shares purchased from such stockholder. If the tendering stockholder has not been issued a TIN and has applied for one or intends to apply for one in the near future, such stockholder should write “Applied For” in the space provided for the TIN in Part I of the Substitute Form W-9, and sign and date the Substitute Form W-9. If “Applied For” is written in Part I and the Depositary is not provided with a TIN within 60 days, the Depositary will withhold 28% on all payments of the purchase price to such stockholder until a TIN is provided to the Depositary.

IMPORTANT: THIS LETTER OF TRANSMITTAL (OR MANUALLY SIGNED FACSIMILE HEREOF), PROPERLY COMPLETED AND DULY EXECUTED (TOGETHER WITH ANY REQUIRED SIGNATURE GUARANTEES (OR, IN THE CASE OF A BOOK-ENTRY TRANSFER, AN AGENT’S MESSAGE) AND SHARE CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER REQUIRED DOCUMENTS) OR A PROPERLY COMPLETED AND DULY EXECUTED NOTICE OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE DEPOSITARY PRIOR TO THE EXPIRATION DATE (AS DEFINED IN THE OFFER TO PURCHASE) OR THE EXPIRATION OF A SUBSEQUENT OFFERING PERIOD, IF APPLICABLE.

Under U.S. federal income tax law, a stockholder whose tendered Shares are accepted for payment is generally required to provide the Depositary (as payer) with such stockholder’s correct TIN on Substitute Form W-9 provided herewith. If such stockholder is an individual, the TIN generally is such stockholder’s social security number. If the Depositary is not provided with the correct TIN, the stockholder may be subject to a $50

penalty imposed by the Internal Revenue Service and payments that are made to such stockholder with respect to Shares purchased pursuant to the Offer may be subject to backup withholding of 28%. In addition, if a stockholder makes a false statement that results in no imposition of backup withholding, and there was no reasonable basis for making such statement, a $500 penalty may also be imposed by the Internal Revenue Service.

Certain stockholders (including, among others, corporations and certain non-U.S. individuals) are not subject to these backup withholding and reporting requirements. In order for a non-U.S. individual to qualify as an exempt recipient, such individual must submit a statement (Internal Revenue Service Form W-8BEN), signed under penalties of perjury, attesting to such individual’s exempt status. Forms of such statements can be obtained from the Depositary. See the enclosed “Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9” for additional instructions. Each stockholder should consult his or her tax advisor as to such stockholder’s qualification for exemption from backup withholding and the procedure for obtaining such exemption.

If backup withholding applies, the Depositary is required to withhold 28% of any payments made to the stockholder. Backup withholding is not an additional tax. Rather, the U.S. federal income tax liability of persons subject to backup withholding can be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained provided that the required information is timely furnished to the Internal Revenue Service.

To prevent backup withholding on payments that are made to a stockholder with respect to Shares purchased pursuant to the Offer, each stockholder is required to notify the Depositary of such stockholder’s correct TIN by completing the form below certifying that (a) the TIN provided on Substitute Form W-9 is correct (or that such stockholder is awaiting a TIN), and (b)(i) such stockholder has not been notified by the Internal Revenue Service that he is subject to backup withholding as a result of a failure to report all interest or dividends or (ii) the U.S. Internal Revenue Service has notified such stockholder that such stockholder is no longer subject to backup withholding.

Each tendering stockholder is required to give the Depositary the TIN (e.g., social security number or employer identification number) of the record holder of Shares tendered hereby. If Shares are in more than one name or are not in the name of the actual owner, consult the enclosed “Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9” for additional guidance on which number to report. If the tendering stockholder has not been issued a TIN and has applied for a number or intends to apply for a number in the near future, the stockholder should write “Applied For” in the space provided for the TIN in Part I, and sign and dated the Substitute Form W-9. If “Applied For” is written in Part I and the Depositary is not provided with a TIN within 60 days, the Depositary will withhold 28% of all payments of the purchase price to such stockholder until a TIN is provided to the Depositary.

Facsimiles of the Letter of Transmittal, properly completed and duly signed, will be accepted. The Letter of Transmittal and Share Certificates and any other required documents should be sent or delivered by each stockholder or such stockholder’s broker, dealer, commercial bank, trust company or other nominee to the Depositary at one of its addresses or to the facsimile number set forth below.

Questions or requests for assistance may be directed to the Information Agent at its address and telephone numbers as set forth below. Requests for additional copies of the Offer to Purchase, the Supplement, this Letter of Transmittal, the Notice of Guaranteed Delivery and the Guidelines for Certification of the Guidelines for Certifcation of Taxpayer Identification Number on Substitute Form W-9 may be directed to the Information Agent, and copies will be furnished promptly at Purchaser’s expense. Free copies of the tender offer materials may also be found at the Security and Exchange Commission’s website at www.sec.gov or at Parent’s website at ww.samson.com when available. Stockholders may also contact their brokers, dealers, commercial banks, trust companies or other nominees for assistance concerning the Offer.
