TO TENDER
ALL OUTSTANDING
8.125% SENIOR NOTES DUE 2019

KODIAK OIL & GAS CORP.
PURSUANT TO THE PROSPECTUS
DATED                    , 2012

THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON                    , 2012 (THE "EXPIRATION DATE"), UNLESS EXTENDED. TENDERS MAY BE WITHDRAWN PRIOR TO 5:00 P.M., NEW YORK CITY TIME, ON THE EXPIRATION DATE.

The Exchange Agent for the Exchange Offer is:

U.S. Bank National Association
60 Livingston Avenue
St. Paul, MN 55107
(800) 934-6802

        If you wish to exchange your issued and outstanding 8.125% Senior Notes due 2019 ("Old Notes") for an equal aggregate principal amount of newly issued 8.125% Senior Notes due 2019 ("New Notes") with materially identical terms that have been registered under the Securities Act of 1933, as amended (the "Securities Act") pursuant to the exchange offer, you must validly tender (and not withdraw) your Old Notes to the Exchange Agent prior to the Expiration Date.

        We refer you to the prospectus, dated                    , 2012 (the "Prospectus"), of Kodiak Oil & Gas Corp., a Yukon Territory corporation (the "Issuer"), which, together with this Letter of Transmittal (the "Letter of Transmittal"), describe the Issuer's offer (the "Exchange Offer") to exchange the Old Notes for a like aggregate principal amount of New Notes. Capitalized terms used but not defined herein have the respective meaning given to them in the Prospectus.

        The Issuer reserves the right, at any time or from time to time, to extend the Exchange Offer at its discretion, in which event the term "Expiration Date" shall mean the latest date to which the Exchange Offer is extended. The Issuer shall notify the Exchange Agent and each registered holder of the Old Notes of any extension by oral (promptly followed in writing) or written notice prior to 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date.

        This Letter of Transmittal is to be used by holders of the Old Notes. Tender of Old Notes is to be made according to the Automated Tender Offer Program ("ATOP") of The Depository Trust Company ("DTC") pursuant to the procedures set forth in the Prospectus under the caption "Exchange Offer—Exchange Offer Procedures." DTC participants that are accepting the Exchange Offer must transmit their acceptance to DTC, which will verify the acceptance and execute a book-entry delivery to the Exchange Agent's DTC account. DTC will then send a computer generated message known as an "agent's message" to the Exchange Agent for its acceptance. For you to validly tender your Old Notes in the Exchange Offer, the Exchange Agent must receive, prior to the Expiration Date, an agent's message under the ATOP procedures that confirms that:

•

DTC has received your instructions to tender your Old Notes; and

•

you agree to be bound by the terms of this Letter of Transmittal.

        BY USING THE ATOP PROCEDURES TO TENDER OLD NOTES, YOU WILL NOT BE REQUIRED TO DELIVER THIS LETTER OF TRANSMITTAL TO THE EXCHANGE AGENT. HOWEVER, YOU WILL BE BOUND BY ITS TERMS, AND YOU WILL BE DEEMED TO HAVE MADE THE ACKNOWLEDGMENTS AND THE REPRESENTATIONS AND WARRANTIES IT CONTAINS, JUST AS IF YOU HAD SIGNED IT.

PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY.

6.

If you are a broker-dealer and Old Notes held for your own account were not acquired as a result of market-making or other trading activities, such Old Notes cannot be exchanged pursuant to the Exchange Offer.
