Appendix A

AFFILIATE GUARANTEE

1. Guarantee. With respect to the 8.125% Senior Notes due 2019 (the “Notes”) issued by Kodiak Oil & Gas Corp. (“Kodiak”) pursuant to an Indenture, dated as of November 23, 2011, as amended (as heretofore or hereafter amended and supplemented, the “Indenture”), by and among Kodiak, as issuer, Kodiak Oil & Gas (USA), Inc. and Kodiak Williston, LLC, as subsidiary guarantors, Xxxxxxx Petroleum Corporation, as parent guarantor, U.S. Bank National Association, as trustee (the “Trustee”), and Computershare Trust Company of Canada, as Canadian trustee (the “Canadian Trustee”), Xxxxxxx Oil and Gas Corporation, a Delaware corporation (the “Affiliate Guarantor”), unconditionally and irrevocably guarantees the prompt payment, when due, of any amount owed to the holders of the Notes under the Notes and the Indenture and any other amounts due pursuant to the Indenture (the “Obligations”).

2. Nature of Guarantee. The Affiliate Guarantor’s obligations hereunder shall not be affected by any circumstance relating to the Obligations that might otherwise constitute a legal or equitable discharge of or defense to the Affiliate Guarantor. The Affiliate Guarantor agrees that the Trustee, the Canadian Trustee or the holders of the Notes may resort to the Affiliate Guarantor for payment of any of the Obligations whether or not the Trustee, the Canadian Trustee, or the holders of the Notes shall have first proceeded against Kodiak or any other obligor principally or secondarily obligated with respect to the Obligations. The Trustee, the Canadian Trustee or the holders of the Notes shall not be obligated to file any claim relating to the Obligations in the event that Kodiak becomes subject to a bankruptcy, reorganization or similar proceeding, and the failure of the Trustee, the Canadian Trustee or the holders of the Notes to so file shall not affect the Affiliate Guarantor’s obligations hereunder. In the event that any payment to the Trustee, the Canadian Trustee or the holders of the Notes in respect of the Obligations is rescinded or must otherwise be returned for any reason whatsoever, the Affiliate Guarantor shall remain liable hereunder with respect to such Obligations as if such payment had not been made.

3. Changes in Obligations, and Agreements Relating thereto; Waiver of Certain Notices. The Affiliate Guarantor agrees that the Trustee, the Canadian Trustee or the holders of the Notes may at any time and from time to time, either before or after the maturity thereof, without notice to or further consent of the Affiliate Guarantor, extend the time of payment of, or renew all or any part of the Obligations, and may also make any agreement with Kodiak for the extension, renewal, payment, compromise, discharge or release thereof, in whole or in part, or for any modification of the terms thereof or of any agreement between the Trustee, the Canadian Trustee or the holders of the Notes and Kodiak, without in any way impairing or affecting this Guarantee. The Affiliate Guarantor waives notice of the acceptance of this Guarantee and of the Obligations, presentment, demand for payment, notice of dishonor and protest.

4. Expenses. The Affiliate Guarantor agrees to pay on demand all reasonable fees and out-of-pocket expenses (including the reasonable fees and expenses of one firm of counsel representing the Trustee, the Canadian Trustee or the holders of the Notes) in any way relating to the enforcement or protection of the rights of the Trustee, the Canadian Trustee or the holders of the Notes hereunder, provided that the Affiliate Guarantor shall not be liable for any expenses of the Trustee, the Canadian Trustee or the holders of the Notes if no payment under this Guarantee is due.

5. Subrogation. Upon payment of the Obligations to the Trustee, the Canadian Trustee or the holders of the Notes in full, the Affiliate Guarantor shall be subrogated to the rights of the Trustee, the Canadian Trustee or the holders of the Notes against Kodiak with respect to the Obligations, and the Trustee, the Canadian Trustee or the holders of the Notes agree to take at the Affiliate Guarantor’s expense such steps as the Affiliate Guarantor may reasonably request to implement such subrogation.

6. No Waiver; Cumulative Rights. No failure on the part of the Trustee, the Canadian Trustee or the holders of the Notes to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by the Trustee, the Canadian Trustee or the holders of the Notes of any right, remedy or power hereunder preclude any other or further exercise of any right, remedy or power. Each and every right, remedy and power hereby granted to the Trustee, the Canadian Trustee and the holders of the Notes or allowed it or them by law or in equity or other agreement shall be cumulative and not exclusive of any other, and may be exercised by the Trustee, the Canadian Trustee or the holders of the Notes at any time or from time to time.

7. Assignment. Nothing contained in this Guarantee shall prevent any consolidation or merger of Affiliate Guarantor with or into any other Person (whether or not affiliated with the Affiliate Guarantor), or successive consolidations or mergers in which Affiliate Guarantor or its successor shall be a party or parties, or shall prevent any conveyance or transfer of the properties and assets of Affiliate Guarantor as an entirety or substantially as an entirety to any other Person (whether or not affiliated with Affiliate Guarantor) lawfully entitled to acquire the same; provided, however, that upon any such consolidation, merger, conveyance or transfer, the due and punctual performance and observance of all of the covenants and conditions of the Guarantee to be performed by Affiliate Guarantor, shall be expressly assumed, in form reasonably satisfactory to the Trustee and the Canadian Trustee, executed and delivered to the Trustee and the Canadian Trustee by the person (if other than the Affiliate Guarantor) formed by such consolidation, or into which Affiliate Guarantor shall have been merged, or by the Person which shall have acquired such properties and assets.

8. Notices. All notices to or demands on the Affiliate Guarantor shall be deemed effective when received, shall be in writing and shall be delivered by hand or by registered mail (or similar type mail), or by facsimile transmission promptly confirmed by registered mail (or similar type mail), addressed to the Affiliate Guarantor at:

Xxxxxxx Oil and Gas Corporation

Attention: Corporate Secretary

or to such other address or fax number as the Affiliate Guarantor shall have notified the Trustee and the Canadian Trustee in a written notice delivered to the Trustee and the Canadian Trustee at the address or facsimile number specified in the Indenture.

9. Continuing Guarantee. This Guarantee shall remain in full force and effect and shall be binding on the Affiliate Guarantor, its successors and assigns until all of the Obligations have been satisfied in full. Notwithstanding the foregoing or any other provision hereof to the contrary, in the event that the Affiliate Guarantor ceases to be an Affiliate (as defined in the Indenture) of Kodiak as the result of any transaction or series of transactions that complies with the Indenture, then the Affiliate Guarantor shall be released from this Guarantee upon the consummation thereof without the necessity of any further action by any party.

11. Governing Law. This Guarantee shall be governed by and construed in accordance with the laws of the State of New York.
