ANNEX B TO THE FIRST SUPPLEMENTAL INDENTURE

[FORM OF REVERSE SIDE OF EXCHANGE NOTE]

8.50% Senior Secured Second Lien Notes due 2023

Capitalized terms used herein but not defined shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

1. Interest. Northern Oil and Gas, Inc., a Delaware corporation (the “Company”), promises to pay Cash Interest on the principal amount of this Note at 8.50% per annum from May 15, 2018 until maturity (the “Cash Interest Rate”); provided, however, beginning on July 1, 2018, the Company shall pay additional interest in kind at 1.00% per annum (the “PIK Interest Rate”) (in addition to the Cash Interest Rate) on the then outstanding principal amount of this Note (a “PIK Note Payment”) by increasing the principal amount of this Note or by issuing additional Notes in a principal amount equal to such interest (“PIK Interest”) on the applicable Interest Payment Date. Notwithstanding the foregoing, if the Company delivers a PIK Interest Suspension Certificate to the Trustee on or before the Compliance Certificate Due Date for the most recently ended Measurement Fiscal Quarter, the PIK Interest shall not accrue from the Interest Payment Date following the delivery of such PIK Interest Suspension Certificate through the Interest Payment Date following the Compliance Certificate Due Date for the immediately succeeding Measurement Fiscal Quarter; provided, however, if a PIK Interest Suspension Certificate is not delivered by such Compliance Certificate Due Date, PIK Interest shall immediately and automatically begin accruing on the then outstanding principal amount of this Note on the next succeeding Interest Payment Date and shall continue to accrue until the next Interest Payment Date following the date on which a PIK Interest Suspension Certificate is delivered in compliance with Section 2.13 of the Indenture. The Company will pay interest quarterly in arrears on January 1, April 1, July 1 and October 1 of each year, commencing July 1, 2018 (each an “Interest Payment Date”), and at Stated Maturity, the Company will pay interest from the most recent date to which interest has been paid to the Stated Maturity date. If an Interest Payment Date falls on a day that is not a Business Day, the interest payment to be made on such Interest Payment Date will be made on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date, and no additional interest will accrue solely as a result of such delayed payment. Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of original issuance; provided that if there is no existing Default or Event of Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date, except in the case of the original issuance of Notes, in which case interest shall accrue from the date of authentication. The Company shall pay in cash (i) interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate that is 3% higher than the then applicable interest rate on the Notes to the extent lawful and (ii) interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the rate that is 3% higher than the then applicable interest rate on the Notes to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve (12) 30-day months.

ANNEX B TO THE FIRST SUPPLEMENTAL INDENTURE

PIK Note Payments shall be effected (i) with respect to Notes in certificated form, by issuing PIK Notes in certificated form in an aggregate principal amount equal to the amount of PIK Interest to be paid on the principal amount of Notes held by each Holder on the relevant record date, after giving effect to any interest to be paid in Cash Interest (rounded up to the nearest $1.00) or (ii) with respect to Global Notes, by increasing the principal amount of the outstanding Global Note by an amount equal to the amount of PIK Interest for the applicable Interest Period (rounded up to the nearest $1.00), and the Trustee will, at the written order of the Company signed by an Officer, authenticate and deliver such PIK Notes on the Interest Payment Date in certificated form for original issuance to the Holders of record on the relevant record date or cause such increase in principal amount with respect to Global Notes. Following an increase in the principal amount of the outstanding Global Notes as a result of a PIK Note Payment, the Notes will bear interest on such increased principal amount from and after the date of such PIK Note Payment. Any PIK Notes issued in certificated form will be dated as of the applicable Interest Payment Date and will bear interest from and after such date.

Method of Payment. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the December 15, March 15, June 15 or September 15 next preceding the Interest Payment Date, even if such Notes are cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. Holders must surrender Notes to the Paying Agent to collect payments of principal and premium, if any, together with accrued and unpaid interest due at maturity. The Notes will be payable as to principal, Cash Interest, PIK Interest, if any, premium, if any, at the office or agency of the Company maintained for such purpose, or, at the option of the Company, payment of Cash Interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders, and provided that payment by wire transfer of immediately available funds to an account in the United States of America will be required with respect to any amounts due on all Global Notes and all other Notes the Holders of which shall have provided wire transfer instructions to the Company to be provided to the Paying Agent or the Paying Agent. Notwithstanding the foregoing, if this Note is a Global Note, payment may be made pursuant to the Applicable Procedures of the Depository as permitted in the Indenture. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts, except in the case of any PIK Interest.

Paying Agent, Collateral Agent and Registrar. Initially, Wilmington Trust, National Association, the Trustee under the Indenture, will act as Paying Agent, Collateral Agent and Registrar. The Company may appoint and change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

ANNEX B TO THE FIRST SUPPLEMENTAL INDENTURE

If the Company or any Guarantor Transfers Oil and Gas Properties (or any Equity Interests in any Guarantor owning such Oil and Gas Properties) or Liquidates any Swap Agreement (in each case, other than Transfers permitted under Section 4.37(a)(i), Section 4.37(a)(iii), Section 4.37(a)(v), Section 4.37(a)(vi) or Section 4.37(a)(viii)), then the Company shall, subject to the prepayment provisions in the First Lien Credit Agreement or, if the First Lien Credit Agreement ceases to exist, any substantively equivalent provision in the Credit Facility, within ten (10) Business Days after such Transfer or Liquidation, make an Asset Sale Offer to all Holders of Notes to purchase the maximum principal amount of Notes that may be purchased from such Net Cash Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of principal amount of such Net Cash Proceeds in excess of $20,000,000 plus accrued and unpaid interest thereon to the Settlement Date plus the Make Whole Premium, subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Settlement Date, and will be payable in cash. Notwithstanding the foregoing, the company may, as long as no Default or Event of Default exists, within ten (10) Business Days after such Transfer or Liquidation, notify the Trustee and the Holders that it intends to reinvest such Net Cash Proceeds; provided that if no Default or Event of Default exists and the Company notifies the Trustee and the Holders that it plans to reinvest such Net Cash Proceeds in the acquisition or development of Oil and Gas Properties constituting Proved Reserves, then it shall do so within ninety (90) days after the date of such Transfer or Liquidation (provided that the execution of a binding AFE during such period shall be deemed to be a reinvestment so long as the amounts owed under such AFE are funded within 180 days after the date such AFE is executed); provided further, that (A) if the Company fails to make such reinvestment in such period, it shall make an Asset Sale Offer in amount equal to 100% of such Net Cash Proceeds within ten (10) Business Days after the expiration of such 90-day period (or, as applicable, after the expiration of the 180-day period following the execution of a binding AFE) and (B) in no event shall the aggregate amount of Net Cash Proceeds permitted to be reinvested exceed $50,000,000 during the term of this Indenture. If the aggregate principal amount of Notes tendered into such Asset Sale Offer exceeds the amount of Net Cash Proceeds, the Trustee shall select the Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of $1.00, or integral multiples of $1.00 in excess thereof, shall be purchased). Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” on the reverse of the Notes.

Guarantees. The payment by the Company of the principal of and interest, premium, if any, on, the Notes is fully and unconditionally guaranteed on a joint and several senior unsecured basis by each of the Guarantors to the extent set forth in the Indenture.

The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and the Company may require a Holder to pay any Taxes due on transfer or exchange. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the transfer of any Notes for a period of fifteen (15) days before a selection of Notes to be redeemed.

ANNEX B TO THE FIRST SUPPLEMENTAL INDENTURE

Material Adverse Effect, in either such case, shall have been rendered against a Note Party and the same shall remain undischarged for a period of forty-five (45) consecutive days during which execution shall not be effectively stayed, or any action shall be legally taken by a judgment creditor to attach or levy upon any assets of a Note Party to enforce any such judgment; (x) an ERISA Event shall have occurred that, when taken together with all other ERISA Events that have occurred, could reasonably be expected to result in a Material Adverse Effect; and (xi) the Note Documents cease to be in full force and effect or are repudiated or cease to create a valid and perfected lien in favor of the Collateral Agent. If any Event of Default occurs and is continuing, the Trustee, by written notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Notes, by written notice to the Company with a copy to the Trustee, may declare all the Notes to be due and payable immediately. Notwithstanding the preceding, in the case of an Event of Default arising from such events of bankruptcy, insolvency or reorganization described in Section 6.01(h) or 6.01(i) of the Indenture, all outstanding Notes will become due and payable immediately without further action or notice, together with all accrued and unpaid interest and premium (including the Applicable Premium and Make Whole Premium), if any, thereon. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power conferred on it. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal, interest, premium, if any) if it in good faith determines that withholding notice is in their interests. The Holders of a majority in principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all the Notes rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except with respect to nonpayment of principal, interest, premium, if any, that have become due solely because of the acceleration) have been cured or waived. The Holders of a majority in principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of the principal of, or interest, premium (including the Applicable Premium and Make Whole Premium), if any, on, the Notes. The Company is required to deliver to the Trustee annually an Officers’ Certificate regarding compliance with the Indenture, and, so long as any Notes are outstanding, the Company is required upon any Officer of the Company becoming aware of any Default or Event of Default, to deliver to the Trustee a statement describing such Default or Event of Default, its status and what action the Company is taking or proposes to take in respect thereof.

Defeasance and Discharge. The Notes are subject to defeasance and discharge upon the terms and conditions specified in the Indenture.

No Recourse Against Others. No director, officer, partner, employee, incorporator, manager or shareholder or other owner of Equity Interests of the Company or any Guarantor, as such, shall have any liability for any obligations of the Company or any Guarantor under the Notes, the Subsidiary Guarantee or the Indenture, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.
