Except as otherwise provided in this Agreement as to LIBOR Tranches, should any such payment become due and payable on a day other than a Business Day, the maturity of such payment shall be extended to the next succeeding Business Day, and, in the case of a payment of principal or past due interest, interest shall accrue and be due and payable thereon for the period of such extension. Each payment under a Loan Document shall be due and payable at the place provided therein or, if no specific place of payment is provided, shall be due and payable at the place of payment of the Note.

SECTION 2.7. USE OF PROCEEDS. In no event shall the proceeds of the Revolving Loan be used directly or indirectly for the purpose, whether immediate, incidental or ultimate, of purchasing, acquiring or carrying any "margin stock" (as such term is defined in Regulation U promulgated by the Board of Governors of the Federal Reserve System) or to extend credit to others directly or indirectly for the purpose of purchasing or carrying any such margin stock or margin securities. Borrower represents and warrants to BOTW that Borrower is not engaged principally, or as one of its important activities, in the business of extending credit to others for the purpose of purchasing or carrying such margin stock. The proceeds of the Revolving Loan shall be used solely for the funding of capital expenditures relating to the acquisition, exploration, drilling, development and/or workover of oil and gas properties by Borrower, general working capital purposes, the issuance of Letters of Credit on terms reasonably acceptable to BOTW and other uses in the ordinary course of Borrower's business.

SECTION 2.8. BORROWING BASE PROCEDURES. Based upon the engineering reports submitted by Borrower pursuant to Section 6.1(b) below and upon such other information and data as BOTW deems relevant, BOTW will redetermine the Borrowing Base as of the first day of each Borrowing Base Period. BOTW and Borrower shall each have the option to request one (1) unscheduled interim Borrowing Base review in between each scheduled review date. BOTW shall advise Borrower of each redetermination of the Borrowing Base by providing to Borrower a Borrowing Base Notice approximately ten (10) days prior to the effectiveness of the redetermined Borrowing Base; provided that if, due to any failure by Borrower to submit in a timely manner any engineering report or other information required to be submitted by Borrower hereunder or, if requested in writing by BOTW, any additional information or data needed in connection with a redetermination of the Borrowing Base or due to any other reason beyond the control of BOTW, BOTW does not provide a Borrowing Base Notice at the time described above, then, unless BOTW gives notice to the contrary to Borrower, the Borrowing Base from the previous period shall be carried over into the new period until a Borrowing Base Notice has been sent to Borrower by BOTW.

III. SECURITY; FEES; LIBOR PROVISIONS; TAXES; INCREASED CAPITAL

SECTION 3.1. THE SECURITY. The Obligations will be secured on a pari passu basis by any and all Security Documents executed and delivered contemporaneously with the execution and delivery of this Agreement and any additional Security Documents hereafter delivered by any Obligated Person and accepted by BOTW. The Liens provided by the Security Documents shall be senior to and have priority over any other Liens which may arise contemporaneously with or subsequent to the execution of this Agreement.

SECTION 3.2. PERFECTION AND PROTECTION OF SECURITY INTERESTS AND LIENS. Borrower will from time to time deliver to BOTW any amendments, financing statements, continuation statements, extension agreements and other documents, properly completed and executed (and acknowledged when required) by Borrower in form and substance reasonably satisfactory to BOTW, which BOTW may request for the purpose of perfecting, confirming or protecting BOTW's Liens and other rights in the Collateral.

SECTION 3.3. BANK ACCOUNTS AND OFFSET. To secure the repayment of the Obligations, Borrower hereby grants to BOTW a security interest, a lien, and a right of offset, each of which shall be upon and against: (a) any and all moneys, securities or other property (and the proceeds therefrom) of Borrower now or hereafter held or received by or in transit to BOTW from or for the account of Borrower, whether for safekeeping, custody, pledge, transmission, collection or otherwise, (b) any and all deposits (general or special, time or demand, provisional or final) of Borrower with BOTW, and (c) any other credits and claims of Borrower at any time existing against BOTW, including without limitation claims under certificates of deposit. Upon the occurrence of any Event of Default, BOTW is hereby authorized to foreclose upon, offset, appropriate, and apply, at any time and from time to time, without notice to Borrower other than any notice required under Section 7.1, any and all items hereinabove referred to against the Obligations (whether or not such Obligations are then due and payable).

SECTION 3.4. FEES.

(a) Borrower shall pay to BOTW, for the time period commencing on the date hereof through the Maturity Date (Revolving), on the last day of each calendar quarter prior to the Maturity Date (Revolving) (or, if such last day is not a Business Day, on the next succeeding Business Day), commencing with the calendar quarter ending September 30, 2008, and on the Maturity Date (Revolving) (or, if the Maturity Date (Revolving) is not a Business Day, on the next succeeding Business Day), for the time period from the end of the last such calendar quarter through the Maturity Date (Revolving), a commitment fee in an amount equal to: (1) the

Commitment Fee Rate, times (2) the excess, if any, of the Commitment Amount, over the sum of the aggregate outstanding principal balance of all Advances plus the face amounts of all outstanding Letters of Credit, computed on a daily basis for such calendar quarter or other time period, times (3) the length of such calendar quarter or other time period, expressed as a fraction of a year.

(b) Borrower shall pay to BOTW with respect to each Letter of Credit a fee in an amount equal to the greater of: (1)(A) the applicable Letter of Credit Fee Rate, as in effect for the Business Day on which such Letter of Credit is issued, times (B) the face amount of such Letter of Credit, times (C) the term of such Letter of Credit, expressed in years, or (2) $500.00, which fee shall be due and payable at the time of issuance (and again at the time of any renewal) of such Letter of Credit. Any amendment, transfer, negotiation or other fees related to each Letter of Credit will be paid by Borrower for the account of the issuing bank, upon the terms of the issuing bank's then current fee policy.

(c) Contemporaneously with any and all subsequent increases in the Borrowing Base hereunder, Borrower shall pay to BOTW a fee in an amount equal to: (1) 0.0025, times (2) the incremental amount by which the Borrowing Base is then increased.

(d) Upon the execution and delivery of this Agreement, Borrower shall pay to BOTW a loan origination fee in the amount of $12,500.

SECTION 3.5. SPECIAL LIBOR PROVISIONS.

(a) If BOTW shall reasonably determine (which determination shall, upon notice thereof to Borrower, be conclusive and binding upon Borrower and BOTW) that the introduction of or any change in or in the interpretation of any law makes it unlawful, or any central bank or other governmental authority having jurisdiction asserts that it is unlawful, for BOTW to fund, continue or maintain any LIBOR Tranche, the obligation of BOTW to fund, continue or maintain any such LIBOR Tranche shall, upon such determination, forthwith be suspended until BOTW shall notify Borrower that the circumstances causing such suspension no longer exist, and all LIBOR Tranches shall automatically be converted into the Prime Rate Portion at the end of the then-current LIBOR Interest Periods with respect thereto or sooner, if required by such law or assertion.

(b) If BOTW shall reasonably determine that:

(1) U.S. Dollar deposits in the relevant amount and for the relevant LIBOR Interest Period are not available to BOTW in its relevant market; or

(2) By reason of circumstances affecting BOTW's relevant market, adequate means do not exist for ascertaining the interest rate applicable hereunder to LIBOR Tranches;

then, upon notice from BOTW to Borrower, the obligation of BOTW to include any portion of the Revolving Loan in a LIBOR Tranche shall forthwith be suspended until BOTW shall notify Borrower that the circumstances causing such suspension no longer exist.

(c) Borrower agrees to reimburse BOTW for any increase in the cost to BOTW of, or any reduction in the amount of any sum receivable by BOTW in respect of, funding, continuing or maintaining (or of its obligation to fund, continue or maintain) any LIBOR Tranche; provided that the foregoing shall not apply to increases resulting from general increases in interest rates or general increases in BOTW's administrative expenses or overhead costs. BOTW shall promptly notify Borrower in writing of the occurrence of any such event, such notice to state, in reasonable detail, the reasons therefor and the additional amount required fully to compensate BOTW for such increased cost or reduced amount. Such additional amount shall be due and payable by Borrower to BOTW within fifteen days of Borrower's receipt of such notice, and such notice shall, in the absence of clear error, be conclusive and binding on Borrower.

(d) In the event BOTW shall incur any loss or expense (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by BOTW to fund, continue or maintain any portion of the principal amount of any LIBOR Tranche) as a result of:

(1) Any conversion, repayment or prepayment (whether voluntary or mandatory) of the principal amount of any LIBOR Tranche on a date other than the scheduled last day of the LIBOR Interest Period applicable thereto; or

(2) Any requested LIBOR Tranche not being funded as a LIBOR Tranche in accordance with the provisions of this Agreement or the Interest Rate Election therefor, unless due to circumstances beyond Borrower's control;

then, upon the written notice by BOTW to Borrower, Borrower shall, within fifteen days of receipt thereof, pay BOTW such amount as will (in the reasonable determination of BOTW) reimburse BOTW for such loss or expense. Such written notice (which shall include calculations in reasonable detail) shall, in the absence of clear error, be conclusive and binding upon Borrower.

SECTION 3.6. INCREASED CAPITAL COSTS. If any change in, or the introduction, adoption, effectiveness, interpretation, reinterpretation or phase-in of, any law or regulation, directive, guideline, decision or request (whether or not having the force of law) of any court, central bank, regulator or other governmental authority affects or would affect the amount of capital required or expected to be maintained by BOTW or any Person controlling BOTW, and BOTW reasonably determines that the rate of return on its or such controlling Person's capital as a consequence of the Revolving Loan is reduced to a level below that which BOTW or such controlling Person could have achieved but for the occurrence of any such circumstance, then, in any such case upon notice from time to time by BOTW to Borrower, Borrower hereby agrees to pay to BOTW, within fifteen days of the effective date of such notice, such additional amount (as may be reasonably determined by BOTW) sufficient to compensate BOTW or such controlling Person for such reduction in rate of return. A statement to Borrower by BOTW as to any such additional amount or amounts (including calculations thereof in reasonable detail) shall, in the absence of clear error, be conclusive and binding upon Borrower.

SECTION 3.7. TAXES. All payments by Borrower of principal of, and interest on, the Revolving Loan and all other amounts payable hereunder shall be made free and clear of and without deduction for any present or future income, excise, stamp or franchise taxes and other taxes, fees, duties, withholdings or other charges of any nature whatsoever imposed by any taxing authority, but excluding franchise taxes and taxes imposed on or measured by BOTW's net income or receipts (such non-excluded items being called "Taxes"). In the event that any withholding or deduction from any payment to be made by Borrower hereunder is required in respect of any Taxes pursuant to any applicable law, rule or regulation, Borrower will:

(a) Pay directly to the relevant authority the full amount required to be so withheld or deducted;

(b) Promptly forward to BOTW an official receipt or other documentation reasonably satisfactory to BOTW evidencing such payment to such authority; and

(c) Pay BOTW such additional amount or amounts as may be necessary to ensure that the net amount actually received by BOTW will equal the full amount BOTW would have received had no such withholding or deduction been required.

Moreover, if any Taxes are directly asserted against BOTW with respect to any payment received by BOTW hereunder, BOTW may pay such Taxes and Borrower will promptly pay such additional amounts (including any penalties, interest or expenses) as may be necessary in order that the net

amount received by BOTW after the payment of such Taxes (including any Taxes on such additional amount) shall equal the amount BOTW would have received had not such Taxes been asserted.

If Borrower fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to BOTW the required receipts or other required documentary evidence, then Borrower shall indemnify, save and hold harmless BOTW from and against any incremental Taxes, interest or penalties that may become payable by BOTW as a result of any such failure.

SECTION 3.8. OBLIGATIONS ABSOLUTE. The obligation of Borrower to repay any amount drawn on BOTW pursuant to the terms of a Letter of Credit shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, under all circumstances whatsoever, including without limitation the following circumstances:

(a) The existence of any claim, set-off, defense or other right which Borrower may have at any time against any beneficiary of a Letter of Credit (or any Person for whom any such beneficiary may be acting) or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or any unrelated transactions;

(b) Any statement or any other document presented under any Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect whatsoever; or

(c) Payment by BOTW under any Letter of Credit against presentation of a draft or certificate which does not comply in all material respects with the terms of such Letter of Credit.

Payment by Borrower of a reimbursement obligation in connection with a Letter of Credit issued pursuant to this Agreement shall not be deemed a waiver of any rights of Borrower against BOTW under Section 3.10(d) below.

SECTION 3.9. INDEMNIFICATION. Borrower hereby indemnifies and holds harmless BOTW from and against any and all claims, damages, losses, liabilities, costs or expenses whatsoever which BOTW may incur (or which may be claimed against BOTW by any Person) by reason of or in connection with the execution and delivery or transfer of or payment or failure to pay under any Letter of Credit; provided, however, that Borrower shall not be required to indemnify BOTW for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by the willful misconduct, bad faith or gross negligence of BOTW in connection with paying a draft presented under a Letter of Credit. Nothing in this Section 3.9 is intended to limit the obligation of Borrower to repay any amount drawn on BOTW pursuant to the terms of a Letter of Credit.

SECTION 3.10. LIABILITY OF BOTW. Borrower assumes all risks of the acts or omissions of any beneficiary or permitted transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither BOTW nor any of its employees, officers or directors shall be liable or responsible for:

(a) The use which may be made of any Letter of Credit or for any acts or omissions of any beneficiary or transferee thereof in connection therewith;

(b) The validity, sufficiency or genuineness of documents, or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, insufficient, fraudulent or forged; or

(c) Any other circumstance whatsoever in making or failing to make payment under the Letter of Credit, except only that Borrower shall have a claim against BOTW, and BOTW shall be liable to Borrower, to the extent, but only to the extent, of any direct (as opposed to consequential) damages suffered by Borrower which were caused by:

(1) BOTW's willful misconduct, bad faith or gross negligence in connection with the Letter of Credit; or

(2) BOTW's bad faith or grossly negligent failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a draft and certificate strictly complying with the terms and conditions of such Letter of Credit.

(e) Maintenance of Existence and Qualifications.

(h) Insurance.

Borrower will in all respects conduct its business and affairs in compliance with all laws, regulations, and orders applicable thereto (including those relating to pollution and other environmental matters).

(l) Certifications of Compliance.

Borrower hereby agrees to indemnify, defend and hold harmless BOTW and its successors and assigns and the respective agents, affiliates, officers, directors and employees of BOTW and its successors and assigns from and against any and all claims, losses, demands, actions, causes of action and liabilities whatsoever (including without limitation reasonable attorneys' fees and expenses and costs and expenses reasonably incurred in investigating, preparing or defending against any litigation or claim, action, suit, proceeding or demand of any kind or character) arising out of or resulting from: (a) the Loan Documents (including without limitation the enforcement thereof), except to the extent such claims, losses and liabilities are due to BOTW's gross negligence, bad faith or willful misconduct, (b) any violation on or prior to the Release Date of any Applicable Environmental Law, (c) any act, omission, event or circumstance existing or occurring on or prior to the Release Date (including without limitation the presence on the Collateral or release from the Collateral of hazardous substances or solid wastes disposed of or otherwise released), resulting from or in connection with the ownership, construction, occupancy, operation, use and/or maintenance of the Collateral, regardless of whether the act, omission, event or circumstance constituted a violation of any Applicable Environmental Law at the time of its existence of occurrence, and (d) any and all claims or proceedings (whether brought by a private party or governmental agencies) for bodily injury, property damage, abatement or remediation, environmental damage or impairment or any other injury or damage resulting from or relating to any hazardous or toxic substance, solid waste or contaminated material located upon or migrating into, from or through any of the Collateral (whether or not the release of such materials was caused by Borrower, a tenant or subtenant or a prior owner, tenant or subtenant on the Collateral and whether or not the alleged liability is attributable to the handling, storage, generation, transportation, removal or disposal of such substance, waste or material or the mere presence of such substance, waste or material on the Collateral), for which BOTW may have liability due to the making of the Revolving Loan, the granting of the Security Documents, the exercise of BOTW's rights under the Loan Documents or otherwise. WITHOUT LIMITATION, IT IS THE INTENTION OF BORROWER, AND BORROWER AGREES, THAT THE FOREGOING INDEMNITIES SHALL APPLY TO EACH INDEMNIFIED PARTY WITH RESPECT TO CLAIMS, DEMANDS, LIABILITIES, LOSSES, DAMAGES, CAUSES OF ACTION, JUDGMENTS, PENALTIES, COSTS AND EXPENSES (INCLUDING WITHOUT LIMITATION REASONABLE

ATTORNEYS' FEES) WHICH IN WHOLE OR IN PART ARE CAUSED BY OR ARISE OUT OF THE NEGLIGENCE OF SUCH (AND/OR ANY OTHER) INDEMNIFIED PARTY. However, such indemnities shall not apply to any particular indemnified party (but shall apply to the other indemnified parties) to the extent the subject of the indemnification is caused by or arises out of the gross negligence, bad faith or willful misconduct of such particular indemnified party. The foregoing indemnities shall not terminate upon the Release Date or upon the release, foreclosure or other termination of the Security Documents, but will survive the Release Date, foreclosure of the Security Documents or conveyances in lieu of foreclosure, and the repayment of the Revolving Loan and the discharge and release of the Security Documents and the other documents evidencing and/or securing the Revolving Loan.

VIII. MISCELLANEOUS

SECTION 8.1. WAIVER AND AMENDMENT. No failure or delay by BOTW in exercising any right, power or remedy which it may have under any of the Loan Documents shall operate as a waiver thereof or of any other right, power or remedy, nor shall any single or partial exercise by BOTW of any such right, power or remedy preclude any other or further exercise thereof or of any other right, power or remedy. No waiver of any provision of any Loan Document and no consent to any departure therefrom shall ever be effective unless it is in writing and signed by BOTW, and then such waiver or consent shall be effective only in the specific instances and for the purposes for which given and to the extent specified in such writing. No notice to or demand on any Obligated Person shall in any case of itself entitle any Obligated Person to any other or further notice or demand in similar or other circumstances. No modification or amendment of or supplement to this Agreement or the other Loan Documents shall be valid or effective unless the same is in writing and signed by the party against whom it is sought to be enforced.

SECTION 8.2. SURVIVAL OF AGREEMENTS; CUMULATIVE NATURE. All of the Obligated Persons' various representations, warranties, covenants and agreements in the Loan Documents shall survive the execution and delivery of this Agreement and the other Loan Documents and the performance hereof and thereof, including without limitation the making or granting of the Revolving Loan and the delivery of the Note and the other Loan Documents, and shall further survive until all of the Obligations are paid in full to BOTW and all of BOTW's obligations to Borrower are terminated. All statements and agreements contained in any certificate or other instrument delivered to BOTW under any Loan Document shall be deemed representations and warranties by Borrower to BOTW and/or agreements and covenants of Borrower under this Agreement. The representations, warranties, and covenants made by the Obligated Persons in the Loan Documents, and the rights, powers, and privileges granted to BOTW in the Loan Documents, are cumulative, and no Loan Document shall be construed in the context of another to diminish, nullify, or otherwise reduce the benefit to BOTW of any such representation, warranty, covenant, right, power or privilege. In particular and without limitation, no exception set out in this Agreement to any representation, warranty or covenant herein contained shall apply to any similar representation, warranty or covenant contained in any other Loan Document, and each such similar representation, warranty or covenant shall be subject only to those exceptions which are expressly made applicable to it by the terms of the various Loan Documents.

SECTION 8.3. NOTICES. All notices, requests, consents, demands and other communications required or permitted under any Loan Document shall be in writing and, unless otherwise specifically provided in such Loan Document, shall be deemed sufficiently given or furnished if delivered by personal delivery, by expedited delivery service with proof of delivery, or by registered or certified United States mail, return receipt requested, postage prepaid, at the addresses specified below (unless

changed by similar notice in writing given by the particular Person whose address is to be changed). Any such notice or communication shall be deemed to have been given upon receipt:


Borrower's address:		▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇
BOTW's address:		▇▇▇ ▇▇^▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇ Attention: ▇▇▇ ▇▇▇▇▇, Vice President

SECTION 8.4. PARTIES IN INTEREST. All grants, covenants and agreements contained in the Loan Documents shall bind and inure to the benefit of the parties thereto and their respective successors and assigns; provided, however, that no Obligated Person may assign or transfer any of its rights or delegate any of its duties or obligations under any Loan Document without the prior consent of BOTW.

SECTION 8.5. GOVERNING LAW. The Loan Documents shall be deemed contracts and instruments made under the laws of the State of Colorado and shall be construed and enforced in accordance with and governed by the laws of the State of Colorado and the laws of the United States of America, except (a) to the extent that the law of another jurisdiction is expressly elected in a Loan Document, and (b) with respect to specific Liens, or the perfection thereof, evidenced by Security Documents covering real or personal property which by the laws applicable thereto are required to be construed under the laws of another jurisdiction. Borrower hereby irrevocably submits itself to the non-exclusive jurisdiction of the state and federal courts of the State of Colorado.

SECTION 8.6. LIMITATION ON INTEREST. BOTW and the Obligated Persons intend to contract in strict compliance with applicable usury law from time to time in effect. In furtherance thereof such persons stipulate and agree that none of the terms and provisions contained in the Loan Documents shall ever be construed to create a contract to pay, for the use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted to be charged by applicable law from time to time in effect. Neither any Obligated Person nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the maximum amount that may be lawfully charged under applicable law from time to time in effect, and the provisions of this section shall control over all other provisions of the Loan Documents which may be in conflict or apparent conflict herewith. BOTW expressly disavows any intention to charge or collect excessive unearned interest or finance charges in the event the maturity of any Obligation is accelerated. If: (a) the maturity of any Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the legal maximum, or (c) BOTW or any other holder of any or all of the Obligations shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Obligations to an amount in excess of that permitted to be charged by applicable law then in effect, then all such sums determined to constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Obligations or, at BOTW's option, promptly returned to Borrower or the other payor thereof upon such determination.

SECTION 8.7. SEVERABILITY. If any term or provision of any Loan Document shall be determined to be illegal or unenforceable all other terms and provisions of the Loan Documents shall nevertheless remain effective and shall be enforced to the fullest extent permitted by applicable law.

SECTION 8.8. COUNTERPARTS. This Agreement may be separately executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so

executed shall be deemed to constitute one and the same Agreement. Delivery of this Agreement and the other documents to be delivered in connection herewith by any party may be effected, without limitation, by faxing a signed counterpart of any such document to BOTW (any party that effects delivery in such manner hereby agreeing to transmit promptly to each of the other parties an actual signed counterpart).

SECTION 8.9. CONFLICTS. To the extent of any irreconcilable conflicts between the provisions of this Agreement and the provisions of any of the Loan Documents, the provisions of this Agreement shall prevail.

SECTION 8.10. ENTIRE AGREEMENT. This Agreement, the Note, the Security Documents and the other Loan Documents from time to time executed in connection herewith state the entire agreement between the parties with respect to the subject matter hereof.

SECTION 8.11. WAIVER OF JURY TRIAL. EACH OF BORROWER AND BOTW HEREBY WAIVE ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION: (A) ARISING UNDER THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR (B) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM IN RESPECT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT. EACH OF BORROWER AND BOTW HEREBY AGREES THAT THE OTHER MAY FILE A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHTS TO TRIAL BY JURY.

SECTION 8.12. USA PATRIOT ACT NOTICE. BOTW hereby notifies Borrower that, pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56, signed into law October 26, 2001 (the "Act")), BOTW is required to obtain, verify and record information that identifies Borrower and other information that will allow BOTW to identify Borrower in accordance with the Act.

BORROWING BASE PROPERTIES

[To be provided by Borrower to BOTW from time to time]

GUARANTY BY CORPORATION

Denver, Colorado
September 11, 2008

This Guaranty, dated as of September 11, 2008, is made by Kodiak Oil & Gas Corporation, a Yukon territory corporation (the "Guarantor"), for the benefit of Bank of the West (with its participants, successors and assigns, the "Lender").

The Lender and Kodiak Oil & Gas (USA), Inc., a Colorado corporation (the "Borrower"), are parties to a Credit Agreement of even date herewith (as the same may be amended, supplemented or restated from time to time, the "Credit Agreement") pursuant to which the Lender may make advances and extend other financial accommodations to the Borrower.

As a condition to extending such credit to the Borrower, the Lender has required the execution and delivery of this Guaranty.

ACCORDINGLY, the Guarantor, in consideration of the premises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, hereby agrees as follows:

1. Definitions. Capitalized terms defined in the Credit Agreement that are used but not otherwise defined herein shall have the meanings given them in the Credit Agreement.

2. Indebtedness Guaranteed. The Guarantor hereby absolutely and unconditionally guarantees to the Lender the full and prompt payment when due, whether at maturity or earlier by reason of acceleration or otherwise, of (i) the Revolving Loan, the Borrower/BOTW Hedging Obligations and any other obligations of Borrower under the Credit Agreement and (ii) any obligations of Borrower to Lender arising out of account overdrafts (all of said sums being hereinafter called the "Indebtedness").

3. Guarantor's Representations and Warranties. The Guarantor represents and warrants to the Lender that (i) the Guarantor is a corporation, duly organized and existing in good standing and has full power and authority to make and deliver this Guaranty; (ii) the execution, delivery and performance of this Guaranty by the Guarantor have been duly authorized by all necessary action of its directors and stockholders and do not and will not violate the provisions of, or constitute a default under, any presently applicable law or its articles of incorporation or bylaws or any agreement presently binding on it; (iii) this Guaranty has been duly executed and delivered by the authorized officers of the Guarantor and constitutes its lawful, binding and legally enforceable obligation; and (iv) the authorization, execution, delivery and performance of this Guaranty do not require notification to, registration with, or consent or approval by, any federal, state or local regulatory body or administrative agency. The Guarantor represents and warrants to the Lender that the Guarantor has a direct and substantial economic interest in the Borrower and expects to derive substantial benefits therefrom and from any loans, credit transactions, financial accommodations, hedging arrangements, discounts, purchases of property and other transactions and events resulting in the creation of the Indebtedness guaranteed hereby, and that this Guaranty is given for a corporate purpose. The Guarantor agrees to rely exclusively on the right to revoke this Guaranty prospectively as to future transactions in accordance with Paragraph 4, if at any time, in the opinion of the directors or officers of the Guarantor, the benefits then being received by the Guarantor in connection with this Guaranty are not sufficient to warrant the continuance of this Guaranty as to the future Indebtedness of the Borrower. Accordingly, so long as this Guaranty is not revoked prospectively in accordance with Paragraph 4, the Lender may rely conclusively on a continuing warranty, hereby made, that the Guarantor continues to be benefited by this Guaranty and the Lender shall have no duty to inquire into or confirm the receipt of any such benefits, and this Guaranty shall be effective and enforceable by the Lender without regard to the receipt, nature or value of any such benefits.

4. Unconditional Nature. No act or thing need occur to establish the Guarantor's liability hereunder, and no act or thing, except full payment and discharge of all of the Indebtedness, shall in any way exonerate the Guarantor hereunder or modify, reduce, limit or release the Guarantor's liability hereunder. This is an absolute, unconditional and continuing guaranty of payment of the Indebtedness and shall continue to be in force and be binding upon the Guarantor, whether or not all of the Indebtedness is paid in full, until this Guaranty is revoked prospectively as to future transactions, by written notice actually received by the Lender, provided that such revocation shall not be effective as to (i) the amount of Indebtedness existing or committed for at the time of actual receipt of such notice by the Lender, (ii) any future hedging arrangements that may be entered into by the Lender and the Borrower or any Borrower/BOTW Hedging Obligations that may arise in the future, or (iii) any renewals, extensions, refinancings or refundings of (i) or (ii).

5. Dissolution or Insolvency of Guarantor. The dissolution or adjudication of bankruptcy of the Guarantor shall not revoke this Guaranty, except upon actual receipt of written notice thereof by the Lender and only prospectively, as to future transactions, as herein set forth. If the Guarantor shall be dissolved or shall be or become insolvent (however defined), then the Lender shall have the right to declare immediately due and payable, and the Guarantor will forthwith pay to the Lender, the full amount of all of the Indebtedness whether due and payable or unmatured. If the Guarantor voluntarily commences or there is commenced involuntarily against the Guarantor a case under the United States Bankruptcy Code, the full amount of all Indebtedness, whether due and payable or unmatured, shall be immediately due and payable without demand or notice thereof.

6. Subrogation, etc. The Guarantor hereby waives all rights that the Guarantor may now have or hereafter acquire, whether by subrogation, contribution, reimbursement, recourse, exoneration, contract or otherwise, to recover from the Borrower or from any property of the Borrower any sums paid under this Guaranty. The Guarantor will not exercise or enforce any right of contribution to recover any such sums from any Person who is a co-obligor with the Borrower or a guarantor or surety of the Indebtedness or from any property of any such Person until all of the Indebtedness shall have been fully paid and discharged.

7. Enforcement Expenses. The Guarantor will pay or reimburse the Lender for all costs, expenses and attorneys' fees paid or incurred by the Lender in endeavoring to collect and enforce the Indebtedness and in enforcing this Guaranty.

8. Lender's Rights. The Lender shall not be obligated by reason of its acceptance of this Guaranty to engage in any transactions with or for the Borrower. Whether or not any existing relationship between the Guarantor and the Borrower has been changed or ended and whether or not this Guaranty has been terminated or revoked, the Lender may enter into transactions resulting in the creation or continuance of the Indebtedness and may otherwise agree, consent to or suffer the creation or continuance of any of the Indebtedness, without any consent or approval by the Guarantor and without any prior or subsequent notice to the Guarantor. The Guarantor's liability shall not be affected or impaired by any of the following acts or things (which the Lender is expressly authorized to do, omit or suffer from time to time, both before and after termination or revocation of this Guaranty, without consent or approval by or notice to the Guarantor): (i) any acceptance of collateral security, guarantors, accommodation parties or sureties for any or all of the Indebtedness; (ii) one or more extensions or renewals of the Indebtedness (whether or not for longer than the original period) or any modification of the interest rates, maturities, if any, or other contractual terms applicable to any of the Indebtedness or any amendment or modification of any of the terms or provisions of any loan agreement or other agreement under which the Indebtedness or any part thereof arose; (iii) any waiver or indulgence granted to the Borrower, any delay or lack of diligence in the enforcement of the Indebtedness or any failure to institute proceedings, file a claim, give any required notices or otherwise protect any of the Indebtedness; (iv) any full or partial release of, compromise or settlement with, or agreement not to ▇▇▇, the Borrower or any guarantor or other Person liable in respect of any of the

Indebtedness; (v) any release, surrender, cancellation or other discharge of any evidence of the Indebtedness or the acceptance of any instrument in renewal or substitution therefor; (vi) any failure to obtain collateral security (including rights of setoff) for the Indebtedness, or to see to the proper or sufficient creation and perfection thereof, or to establish the priority thereof, or to preserve, protect, insure, care for, exercise or enforce any collateral security; or any modification, alteration, substitution, exchange, surrender, cancellation, termination, release or other change, impairment, limitation, loss or discharge of any collateral security; (vii) any collection, sale, lease or disposition of, or any other foreclosure or enforcement of or realization on, any collateral security; (viii) any assignment, pledge or other transfer of any of the Indebtedness or any evidence thereof; (ix) any manner, order or method of application of any payments or credits upon the Indebtedness; and (x) any election by the Lender under Section 1111(b) of the United States Bankruptcy Code. The Guarantor waives any and all defenses and discharges available to a surety, guarantor or accommodation co-obligor.

9. Waivers by Guarantor. The Guarantor waives any and all defenses, claims, setoffs and discharges of the Borrower, or any other obligor, pertaining to the Indebtedness, except the defense of discharge by payment in full. Without limiting the generality of the foregoing, the Guarantor will not assert, plead or enforce against the Lender any defense of waiver, release, discharge or disallowance in bankruptcy, statute of limitations, res judicata, statute of frauds, anti-deficiency statute, fraud, incapacity, minority, usury, illegality or unenforceability which may be available to the Borrower or any other Person liable in respect of any of the Indebtedness, or any setoff available against the Lender to the Borrower or any other such Person, whether or not on account of a related transaction. The Guarantor expressly agrees that the Guarantor shall be and remain liable for any deficiency remaining after foreclosure of any mortgage or security interest securing the Indebtedness, whether or not the liability of the Borrower or any other obligor for such deficiency is discharged pursuant to statute or judicial decision. The liability of the Guarantor shall not be affected or impaired by any voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all of the assets, marshalling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of, or other similar event or proceeding affecting, the Borrower or any of its assets. The Guarantor will not assert, plead or enforce against the Lender any claim, defense or setoff available to the Guarantor against the Borrower. The Guarantor waives presentment, demand for payment, notice of dishonor or nonpayment and protest of any instrument evidencing the Indebtedness. The Lender shall not be required first to resort for payment of the Indebtedness to the Borrower or other Persons, or their properties, or first to enforce, realize upon or exhaust any collateral security for the Indebtedness, before enforcing this Guaranty.

10. If Payments Set Aside, etc. If any payment applied by the Lender to the Indebtedness is thereafter set aside, recovered, rescinded or required to be returned for any reason (including, without limitation, the bankruptcy, insolvency or reorganization of the Borrower or any other obligor), the Indebtedness to which such payment was applied shall for the purpose of this Guaranty be deemed to have continued in existence, notwithstanding such application, and this Guaranty shall be enforceable as to such Indebtedness as fully as if such application had never been made.

11. Additional Obligation of Guarantor. The Guarantor's liability under this Guaranty is in addition to and shall be cumulative with all other liabilities of the Guarantor to the Lender as guarantor, surety, endorser, accommodation co-obligor or otherwise of any of the Indebtedness or obligation of the Borrower, without any limitation as to amount, unless the instrument or agreement evidencing or creating such other liability specifically provides to the contrary.

12. Financial Information. The Guarantor will deliver to the Lender all financial information concerning the Guarantor required to be delivered under the Credit Agreement.

13. No Duties Owed by Lender. The Guarantor acknowledges and agrees that the Lender (i) has not made any representations or warranties with respect to, (ii) does not assume any responsibility to

the Guarantor for, and (iii) has no duty to provide information to the Guarantor regarding, the enforceability of any of the Indebtedness or the financial condition of the Borrower or any guarantor. The Guarantor has independently determined the creditworthiness of the Borrower and the enforceability of the Indebtedness and until the Indebtedness is paid in full will independently and without reliance on the Lender continue to make such determinations.

14. Miscellaneous. This Guaranty shall be effective upon delivery to the Lender, without further act, condition or acceptance by the Lender, shall be binding upon the Guarantor and the successors and assigns of the Guarantor and shall inure to the benefit of the Lender and its participants, successors and assigns. Any invalidity or unenforceability of any provision or application of this Guaranty shall not affect other lawful provisions and application thereof, and to this end the provisions of this Guaranty are declared to be severable. This Guaranty may not be waived, modified, amended, terminated, released or otherwise changed except by a writing signed by the Guarantor and the Lender. This Guaranty shall be governed by and construed in accordance with the substantive laws (other than conflict laws) of the State of Colorado. The Guarantor hereby (i) consents to the personal jurisdiction of the state and federal courts located in the State of Colorado in connection with any controversy related to this Guaranty; (ii) waives any argument that venue in any such forum is not convenient; (iii) agrees that any litigation initiated by the Lender or the Guarantor in connection with this Guaranty may be venued in either the state or federal courts located in the City and County of Denver, Colorado; and (iv) agrees that a final judgment in any such suit, action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

15. Waiver of Jury Trial. THE GUARANTOR HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF, BASED ON OR PERTAINING TO THIS GUARANTY.

IN WITNESS WHEREOF, this Guaranty has been duly executed by the Guarantor the date first written above.

AND in furtherance thereof Mortgagor warrants, represents, covenants and agrees as follows:

SECTION 2.1 Mortgagor warrants, represents and covenants to and with BOTW that: (a) Mortgagor has the right to receive at all times the "Net Revenue Interest" specified in Exhibit "A" of all Hydrocarbons produced from the ▇▇▇▇▇ located on the Collateral; (b) Mortgagor's share of development and operating costs with respect to any of the ▇▇▇▇▇ or properties included in the Collateral is no greater than the "Working Interest" specified in Exhibit "A" for that well or property (unless Mortgagor's right to receive production proceeds from such well or property has been increased by a proportionate amount over the applicable "Net Revenue Interest" specified for such well or property in Exhibit "A"); (c) Mortgagor is the lawful owner of good and defensible title to the Collateral, free and clear of all liens, security interests, encumbrances and burdens, except liens, security interests and other matters permitted by the terms of the Credit Agreement; (d) each loan, the payment of which constitutes an Obligation hereunder, is or shall be for a business or commercial purpose; and (e) Mortgagor will forever defend the title to the Collateral against the claims of all persons whomsoever claiming or to claim the same or any part thereof.

SECTION 2.2 Mortgagor covenants that, so long as any part of the Obligations remains unpaid or unsatisfied, unless BOTW shall have otherwise consented in writing:

A. Mortgagor shall promptly and, insofar as not contrary to applicable law, at Mortgagor's own expense, file and refile in such offices, at such times and as often as may be necessary, this Instrument and every other instrument in addition or supplemental hereto, including applicable financing statements, as may be necessary to create, perfect, maintain and preserve the lien, encumbrance and security interest intended to be created hereby and the rights and remedies of BOTW hereunder;

B. Mortgagor shall execute, acknowledge and deliver to BOTW such other and further instruments and do such other acts as in the reasonable opinion of BOTW may be necessary or desirable to more fully identify and subject to the lien, encumbrance and security interest and assignment created hereby any property intended by the terms hereof to be covered hereby, to assure the first priority thereof, and otherwise to effect the intent of this Instrument, promptly upon request of BOTW and at Mortgagor's expense; and

C. If the title, interest, lien or encumbrance, as the case may be, of Mortgagor or BOTW to the Collateral or any part thereof, or the security of this Instrument, or the rights or powers of BOTW hereunder, shall be attacked, either directly or indirectly, or if any legal proceedings are commenced involving Mortgagor or the Collateral, Mortgagor shall promptly give written notice thereof to BOTW and at Mortgagor's own expense shall take all reasonable steps diligently to defend against any such attack or proceedings; and BOTW may take such independent action in connection therewith as it may in its discretion deem advisable, and all costs and expenses, including, without limitation, reasonable attorneys' fees and legal expenses, incurred by BOTW in connection therewith shall be a demand obligation owing by Mortgagor to BOTW, shall bear interest at the applicable rate provided in the Credit Agreement, and shall be a part of the Obligations.

XI. COLLECTION OF PROCEEDS OF PRODUCTION

SECTION 3.1 Pursuant to the assignment made by Mortgagor in paragraph B of the granting clause of this Instrument, BOTW is entitled to receive all of the severed and extracted Hydrocarbons produced from or attributed to all of the Interests, together with all of the proceeds thereof. Mortgagor acknowledges and agrees that said assignment is intended to be an absolute and unconditional assignment and not merely a pledge of or creation of a security interest therein or assignment as additional security. Mortgagor hereby authorizes and directs all parties producing, purchasing, receiving or having in their possession any such Hydrocarbons or proceeds to treat and regard BOTW as the party entitled, in Mortgagor's place and stead, to receive such Hydrocarbons and proceeds; and said parties shall be fully protected in so treating and regarding BOTW and shall be under no obligation to see to the application by BOTW of any such proceeds received by it.

SECTION 3.2 All of the proceeds received by BOTW pursuant to Section 3.1 shall be applied by BOTW in accordance with the terms of the Credit Agreement and Section 5.10 below.

SECTION 3.3 Upon any sale of any of the Collateral by or for the benefit of BOTW pursuant to Article V, the Hydrocarbons thereafter produced from or attributed to the part of the Collateral so sold, and the proceeds thereof, shall be included in such sale and shall pass to the purchaser free and clear of the provisions of this Article.

SECTION 3.4 BOTW is hereby absolved from all liability for failure to enforce collection of any such Hydrocarbons or proceeds and from all other responsibility in connection therewith, except the responsibility to account to Mortgagor for proceeds actually received.

SECTION 3.5 Mortgagor shall indemnify BOTW against all claims, actions, liabilities, judgments, costs, attorneys' fees and other charges of whatsoever kind or nature (herein called "Claims") made against or incurred by BOTW as a consequence of the assertion, either before or after the payment in full of the Obligations, that BOTW received Hydrocarbons or proceeds pursuant to this Article which were claimed by or due to third persons. BOTW shall have the right to employ attorneys and to defend against any Claims, and unless furnished with reasonable indemnity, BOTW shall have the right to pay or compromise and adjust all Claims. Mortgagor shall indemnify and pay to BOTW all such amounts as may be paid in respect thereof or as may be successfully adjudicated against BOTW. The liabilities of Mortgagor as set forth in this Section shall survive the termination of this Instrument.

SECTION 3.6 Nothing in this Instrument shall be deemed or construed to create a delegation to or assumption by BOTW of the duties and obligations of Mortgagor under any agreement or contract relating to the Collateral or any portion thereof, and all of the parties to any such contract shall continue to look to Mortgagor for performance of all covenants and other obligations and the satisfaction of all representations and warranties of Mortgagor thereunder, notwithstanding the assignment of production and proceeds herein made or the exercise by BOTW, prior to foreclosure, of any of its rights hereunder or under applicable law.

XII. TERMINATION

If all of the Obligations of Mortgagor shall be paid or performed in full pursuant to the terms and conditions of this Instrument and the instruments evidencing the Obligations and if BOTW has no further obligation to make advances to Mortgagor or in connection with Hedging Obligations of Mortgagor, then BOTW shall, promptly after the request of Mortgagor, execute, acknowledge and deliver to Mortgagor proper instruments in recordable form evidencing the termination and release of this Instrument. Mortgagor shall pay all reasonable legal fees and other out-of-pocket expenses incurred by BOTW for preparing and reviewing such instruments of termination and the execution and delivery thereof, and BOTW may require payment of the same prior to delivery of such instruments. Otherwise, this Instrument shall remain and continue in full force and effect.

XIII. DEFAULT

SECTION 5.1 The occurrence of any "Event of Default" or "Default" (as described in the Credit Agreement or in any agreement entered into in connection with the Hedging Obligations), including without limitation the expiration of any applicable grace period (an "Event of Default"), shall, automatically (as described in the Credit Agreement or in any agreement entered into in connection with the Hedging Obligations), or at the option of BOTW, make all amounts then remaining unpaid on the Obligations immediately due and payable, and the liens, encumbrances and security interests evidenced or created hereby shall be subject to foreclosure in any manner provided for herein or provided for by law.

SECTION 5.2 Upon the occurrence and during the continuance of any Event of Default, BOTW may elect to treat the fixtures included in the Collateral either as real property or as personal property, but not as both, and proceed to exercise such rights as apply to the type of property selected.

SECTION 5.3 Upon the occurrence and during the continuance of any Event of Default, in addition to all other rights and remedies herein conferred, BOTW shall have all of the rights and remedies of a mortgagee under a mortgage with respect to all of the Collateral. This Instrument shall be effective as a mortgage, and, upon the occurrence of an Event of Default, may be foreclosed as to any of the Collateral in any manner permitted by applicable law, and any foreclosure suit may be brought by BOTW. The provisions set forth in this Section 5.3 shall not in any way limit any other provision of this Instrument. Upon the occurrence and during the continuance of an Event of Default, BOTW shall, to the extent permitted by applicable law, have the right and power, but not the obligation, to enter upon and take immediate possession of the real property included in the Collateral or any part thereof, to exclude Mortgagor therefrom, to hold, use, operate, manage and control such real property, to make all such repairs, replacements, alterations, additions and improvements to the same as BOTW may deem proper, to sell all of the severed and extracted Hydrocarbons included in the same subject to the provisions of Article III, to demand, collect and retain all other earnings, proceeds and other sums due or to become due with respect to such real property, accounting for and applying to the payment of the Obligations only the net earnings arising therefrom after charging against the receipts therefrom all costs, expenses, charges, damages and losses incurred by reason thereof plus interest thereon at an annual rate which equals the default rate of interest payable on

overdue principal, as described in the Credit Agreement, as fully and effectually as if BOTW were the absolute owner of such real property and without any liability to Mortgagor in connection therewith.

SECTION 5.4 Upon the occurrence and during the continuance of any Event of Default, BOTW, in lieu of or in addition to exercising any other power, right or remedy herein granted or by law or equity conferred, may proceed by an action or actions in equity or at law for the seizure and sale of the real property included in the Collateral or any part thereof, for the specific performance of any covenant or agreement herein contained or in aid of the execution of any power, right or remedy herein granted or by law or equity conferred, for the foreclosure or sale of such real property or any part thereof under the judgment or decree of any court of competent jurisdiction, for the appointment of a receiver pending any foreclosure hereunder or the sale of such real property or any part thereof or for the enforcement of any other appropriate equitable or legal remedy.

SECTION 5.5 Upon the occurrence and during the continuance of any Event of Default, in addition to all other powers, rights and remedies herein granted or by law or equity conferred, BOTW shall have all of the rights and remedies of an assignee and secured party granted by applicable law, including the Uniform Commercial Code, and shall, to the extent permitted by applicable law, have the right and power, but not the obligation, to take possession of the personal property included in the Collateral, and for that purpose BOTW may enter upon any premises on which any or all of such personal property is located and take possession of and operate such personal property or remove the same therefrom. BOTW may require Mortgagor to assemble such personal property and make it available to BOTW at a place to be designated by BOTW which is reasonably convenient to both parties. The following presumptions shall exist and shall be deemed conclusive with regard to the exercise by BOTW of any of its remedies with respect to personal property:

A. If notice is required by applicable law, at least five days' prior written notice of the time and place of any public sale or of the time after which any private sale or any other intended disposition thereof is to be made shall be reasonable notice to Mortgagor. No such notice is necessary if such property is perishable, threatens to decline speedily in value or is of a type customarily sold on a recognized market.

B. Without in any way limiting the right and authority of BOTW to sell or otherwise dispose of Collateral in a commercially reasonable manner, the following, or any of them, shall be considered commercially reasonable: (1) BOTW may hold a public sale of the Collateral in Denver, Colorado, or San Francisco, California, after having provided Mortgagor with at least five days' notice of such sale (or such minimum notice as required by law, whichever is greater) and after having published notice of such sale by an advertisement in such publication as may be permitted or required under applicable state law, as BOTW determines to be appropriate (which advertisement may be placed in the "classified" section), for a period of not less than five consecutive issues commencing not more than ten days prior to the sale; (2) the Collateral may be sold for cash; and (3) BOTW or any other person owning, directly or indirectly, any interest in any of the Obligations may be a purchaser at such sale.

SECTION 5.6 Upon the occurrence and during the continuance of any Event of Default, BOTW may, with respect to all or any portion of the Collateral, subject to any mandatory requirements of applicable law, sell or have sold the real property or interests therein included in the Collateral or any part thereof at one or more sales, as an entirety or in parcels, at such place or places and otherwise in such manner and upon such notice as may be required by law or by this Instrument, or, in the absence of any such requirement, as BOTW may deem appropriate. BOTW may postpone the sale of such real property or interests therein or any part thereof by public announcement at the time and place of such sale, and from time to time thereafter may further postpone such sale by public announcement made at the time of sale fixed by the preceding postponement. Sale of a part of such real property or interests therein or any defective or irregular sale hereunder will not exhaust the power of sale, and sales may

be made from time to time until all such property is sold without defect or irregularity or the Obligations are paid in full. BOTW shall have the right to appoint one or more attorneys-in-fact to act in conducting the foreclosure sale and executing a deed to the purchaser. It shall not be necessary for any of the Collateral at any such sale to be physically present or constructively in the possession of BOTW.

SECTION 5.7 BOTW or any other person owning, directly or indirectly, any interest in any of the Obligations shall have the right to become the purchaser at any sale made pursuant to the provisions of this Article V and shall have the right to credit upon the amount of the bid made therefor the amount payable to it under or in connection with the Obligations. Recitals contained in any conveyance to any purchaser at any sale made hereunder will conclusively establish the truth and accuracy of the matters therein stated, including without limitation nonpayment of the Obligations and advertisement and conduct of such sale in the manner provided herein or provided by law. Mortgagor hereby ratifies and confirms all legal acts that BOTW may do in carrying out the provisions of this Instrument.

SECTION 5.8 Effective upon the occurrence and during the continuance of any Event of Default, Mortgagor hereby waives and relinquishes, to the maximum extent permitted by law, and subject to any mandatory requirements of applicable law, Mortgagor hereby agrees that Mortgagor shall not at any time hereafter have or assert, any right under any law pertaining to: marshalling, whether of assets or liens, the sale of property in the inverse order of alienation, the exemption of homesteads, the administration of estates of decedents, appraisement, valuation, stay, extension, redemption, subrogation, or abatement, suspension, deferment, diminution or reduction of any of the Obligations (including, without limitation, setoff), now or hereafter in force. Mortgagor expressly agrees that BOTW may offer the Collateral as a whole or in such parcels or lots as BOTW, in its sole discretion elects, regardless of the manner in which the Collateral may be described.

SECTION 5.9 All costs and expenses (including reasonable attorneys' fees, legal expenses, filing fees, and mortgage, transfer, stamp and other excise taxes) incurred by BOTW in perfecting, protecting and enforcing its rights hereunder, whether or not an Event of Default shall have occurred, shall be a demand obligation of Mortgagor to BOTW and shall bear interest at the applicable rate provided in the Credit Agreement, all of which shall be part of the Obligations.

SECTION 5.10 The proceeds of any sale of the Collateral or any part thereof made pursuant to this Article V shall be applied as follows:

A. First, to the payment of all costs and expenses incident to the enforcement of this Instrument, including, without limitation, a reasonable compensation to the agents, attorneys and counsel of BOTW;

B. Second, to the payment or prepayment of the Obligations, in such order as BOTW shall elect; and

C. Third, the remainder, if any, shall be paid to Mortgagor or such other person or persons as may be entitled thereto by law.

SECTION 5.11 Upon any sale made under the powers of sale herein granted and conferred, the receipt of BOTW will be sufficient discharge to the purchaser or purchasers at any sale for the purchase money, and such purchaser or purchasers and the heirs, devisees, personal representatives, successors and assigns thereof will not, after paying such purchase money and receiving such receipt of BOTW, be obligated to see to the application thereof or be in any way answerable for any loss, misapplication or non-application thereof.

XIV. MISCELLANEOUS PROVISIONS

SECTION 6.1 Each and every right, power and remedy hereby granted to BOTW shall be cumulative and not exclusive, and each and every right, power and remedy whether specifically hereby granted or otherwise existing may be exercised from time to time and as often and in such order as may be deemed expedient by BOTW, and the exercise of any such right, power or remedy will not be deemed a waiver of the right to exercise, at the same time or thereafter, any other right, power or remedy. All changes to and modifications of this Instrument must be in writing and signed by Mortgagor and BOTW.

SECTION 6.2 If any provision hereof or of any of the other documents constituting, evidencing or creating all or any part of the Obligations is invalid or unenforceable in any jurisdiction, the other provisions hereof or of said documents shall remain in full force and effect in such jurisdiction and the remaining provisions hereof will be liberally construed in favor of BOTW in order to carry out the provisions hereof and of such other documents. The invalidity of any provision of this Instrument in any jurisdiction will not affect the validity or enforceability of any such provision in any other jurisdiction.

SECTION 6.3 This Instrument will be deemed to be and may be enforced from time to time as an assignment, contract, financing statement, real estate mortgage, or security agreement, and from time to time as any one or more thereof, as is appropriate under applicable state law. A carbon, photographic or other reproduction of this Instrument or any financing statement in connection herewith shall be sufficient as a financing statement for any and all purposes.

SECTION 6.4 Notwithstanding anything to the contrary contained herein, no rate of interest required hereunder or under the Obligations shall exceed the maximum legal rate under applicable law, and, in the event any such rate is found to exceed such maximum legal rate, Mortgagor shall be required to pay only such maximum legal rate.

SECTION 6.5 Insofar as permitted by otherwise applicable law, this Instrument and the Obligations shall be construed under and governed by the laws of the State of Colorado (excluding choice of law and conflict of law rules); provided, however, that, with respect to any portion of the Collateral located outside of the State of Colorado, the laws of the place in which such property is located shall apply to the extent necessary to permit BOTW to enforce or realize upon its rights and remedies hereunder with respect to such property, and any such enforcement or realization proceedings shall be conducted in compliance with the applicable laws of the state where the Collateral is located.

SECTION 6.6 This instrument may be executed in any number of counterparts, each of which will for all purposes be deemed to be an original, and all of which are identical except that: (a) to facilitate recordation, in particular counterparts hereof, portions of Exhibit "A" hereto which describe properties situated in counties or parishes other than the county or parish in which the counterpart is to be recorded have been omitted, and (b) to accommodate different execution formalities for different states in which the Collateral is located, the signature blocks and title pages in counterparts to be filed in certain states may contain captions, witnesses, acceptances and other formalities not included in other counterparts. Each counterpart shall be deemed to be an original for all purposes, and all counterparts shall together constitute but one and the same instrument.

SECTION 6.7 Unless otherwise specified in Exhibit "A" hereto, all recording references in Exhibit "A" hereto are to the official real property records of the county in which the affected land is located. The references in Exhibit "A" hereto to liens, encumbrances and other burdens shall not be deemed to recognize or create any rights in third parties.

SECTION 6.8 All deliveries and notices hereunder shall be deemed to have been duly made or given if made or given in conformity with the provisions of the Credit Agreement.

SECTION 6.9 This Instrument shall bind and inure to the benefit of the respective successors and assigns of Mortgagor and BOTW, including, without limitation, any and all other banks, lending institutions and parties which may participate in the indebtedness evidenced by the Obligations or any of them. Notwithstanding any other provision contained herein, if any property interest granted by this Instrument does not vest on the execution and delivery of this Instrument, it shall vest, if at all, no later than 20 years after the execution and delivery of this Instrument. As used herein, the term "person" shall mean individual, corporation, limited liability company, partnership, joint venture, agency or other form of entity or association.

SECTION 6.10 Some of the above goods are or are to become fixtures on the Land. The above described minerals or other substances of value which may be extracted from the earth (including without limitation oil and gas), and the accounts relating thereto will be financed at the wellhead of the well or ▇▇▇▇▇ located on the Land. This Instrument is to be filed for record in, among other places, the real estate records of each county in which the affected real estate is located; to wit, all of those listed in Exhibit "A." Mortgagor is the owner of a record interest in a portion of the real estate concerned. The mailing address of Mortgagor and the address of BOTW from which information concerning the security interest may be obtained are as set forth above.

SECTION 6.11 BOTW shall be entitled to enforce payment of any indebtedness and performance of any other of the Obligations secured hereby and to exercise all rights and powers under this Instrument or under any other instrument or other agreement or any laws now or hereafter in force, notwithstanding the fact that some or all of said indebtedness and other Obligations secured hereby may now or hereafter be otherwise secured, whether by mortgage, deed of trust, pledge, lien, assignment or otherwise. Neither the acceptance of this Instrument nor its enforcement, whether by court action or pursuant to the power of sale or other powers herein contained shall prejudice or in any manner affect BOTW's right to realize upon or enforce any other security now or hereafter held by BOTW, it being agreed that BOTW shall be entitled to enforce this Instrument and any other security now or hereafter held by BOTW in such order and manner as it may in its absolute discretion determine.

EXECUTED as of the date first above written.

Gentlemen:

Reference is made to that certain Credit Agreement dated as of September 11, 2008, between Kodiak Oil & Gas (USA) Inc., as borrower ("Borrower"), and Bank of the West, as lender (the "Bank"). The above-described Credit Agreement, as it may be amended from time to time, is herein referred to as the "Credit Agreement." Reference is also made to that certain Promissory Note dated September 11, 2008 (the "Note"), in the face amount of $20,000,000, made by Borrower, payable to the order of the Bank.

Payment of the indebtedness owing to the Bank by Borrower is secured by a Mortgage, Security Agreement, Assignment, Financing Statement and Fixture Filing dated as of September 11, 2008 (the "Mortgage"), from Borrower to the Bank.

Pursuant to the terms of the Mortgage, Borrower has assigned to the Bank the proceeds of the sales of oil and gas from the properties described in the Mortgage (the "Proceeds") and has granted to the Bank the right to receive all of the Proceeds directly and to apply them in satisfaction of the obligations of Borrower to the Bank.

Notwithstanding anything to the contrary contained in the Mortgage or in the Credit Agreement, the Bank hereby consents to the suspension of its right to receive the Proceeds directly and grants to Borrower a revocable license to collect the Proceeds, unless and until the Bank elects to revoke such consent and to terminate such license by notice to Borrower in accordance with the notice provisions of the Credit Agreement. Borrower and the Bank understand and agree that the Bank may elect to exercise its right to receive the Proceeds only upon the occurrence of an Event of Default (as defined in the Credit Agreement).

Nothing contained herein will limit the obligation of Borrower to make payments of principal and interest as set forth in the Credit Agreement at the times and in the amounts specified therein.

In the event the Bank does revoke the license granted to Borrower and the suspension of its right to receive the Proceeds as provided herein, upon such revocation, Borrower will then and thereafter receive and hold any such Proceeds as are received in trust pursuant to the relevant sections of the Mortgage and the Credit Agreement for the purpose of protecting the Bank's security interest in the Proceeds and will promptly pay over any and all such Proceeds to the Bank.

Please indicate your acceptance below.
