REVERSE SIDE OF GLOBAL NOTE

7% Senior Subordinated Note due 2014

     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. Whiting Petroleum Corporation, a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Note at 7% per annum from October 4, 2005 until maturity. The Company will pay interest semi-annually in arrears on April 1 and October 1 of each year, commencing April 1, 2006, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”). 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 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 the rate then in effect; it shall pay 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 same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

     2. 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 March 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 2.11 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, premium, if any, and interest at the office or agency of the Company maintained for such purpose within the City and State of New York, or, at the option of the Company, payment of 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 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 or the Paying Agent. 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.

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

     4. Indenture. The Company issued the Notes under an Indenture dated as of October 4, 2005 (“Indenture”) among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. The Notes are unsecured senior subordinated obligations of the Company limited to $250,000,000 aggregate principal amount in the case of Notes issued on the Initial Issuance Date (as defined in the Indenture).

     5. Optional Redemption.

     The Notes shall be subject to redemption at the option of the Company as provided in Section 3.07 of the Indenture.

     6. Mandatory Redemption.

     Except as set forth in paragraph 7 below, the Company shall not be required to make mandatory redemption or sinking fund payments with respect to the Notes or to repurchase the Notes at the option of the Holders.

     7. Repurchase at Option of Holder.

     (a) Within 30 days following the occurrence of a Change of Control, the Company shall make an offer (a “Change of Control Offer”) to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of each Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest to the date of settlement (the “Change of Control Settlement Date”), 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 Change of Control Settlement Date. Within 30 days following a Change of Control, the Company shall mail a notice of the Change of Control Offer to each Holder and the Trustee describing the transaction that constitutes the Change of Control and setting forth the procedures governing the Change of Control Offer as required by Section 4.15 of the Indenture.

     (b) On the 361st day after an Asset Sale, if the aggregate amount of Excess Proceeds then exceeds $50.0 million, the Company shall commence an offer to all Holders of Notes (an “Asset Sale Offer”) pursuant to Section 3.09 of the Indenture, and to all holders of any Pari Passu Indebtedness then outstanding, to purchase the maximum principal amount of Notes and such Pari Passu Indebtedness that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount of the Notes plus accrued and unpaid interest thereon to the date of settlement, 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 Change of Control Settlement Date, in accordance with the procedures set forth in the Indenture. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use such remaining Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes surrendered by Holders thereof and Pari Passu Indebtedness surrendered by holders or lenders, collectively, exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and Pari Passu Indebtedness 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 $1,000, or integral multiples thereof, shall be purchased) on the basis of the aggregate principal amount of tendered Notes and Pari Passu Indebtedness. 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.

     8. Notice of Redemption. Notice of redemption will be mailed at least 30 days but not more than 60 days (except as otherwise provided in the Indenture if the notice is issued in connection with a Legal Defeasance, Covenant Defeasance or Discharge) before the redemption date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger than $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date interest ceases to accrue on Notes or portions thereof called for redemption.

     9. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. 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, it need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed.

     10. Persons Deemed Owners. The registered Holder of a Note may be treated as its owner for all purposes.

     11. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding Notes, and any existing default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes. Without the consent of any Holder of a Note, the Indenture or the Notes may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for the assumption of the Company’s obligations to Holders of the Notes pursuant to Article 5 of the Indenture, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder, provided that any change to conform the Indenture to the Offering Memorandum shall not be deemed to adversely affect the legal rights under the Indenture of any Holder, to secure the Notes or the Subsidiary Guarantees pursuant to Section 4.12 of the Indenture or otherwise, to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture, to add any additional Guarantor with respect to the Notes or to evidence the release of any Guarantor from its Subsidiary Guarantee, in each case as provided in the Indenture, to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the Trust

Indenture Act or to evidence or provide for the acceptance of appointment under the Indenture of a successor Trustee.

     12. Defaults and Remedies. Events of Default include: (i) default for 30 days in the payment when due of interest on the Notes; (ii) default in payment when due of the principal of or premium, if any, on the Notes when due at Stated Maturity, upon optional redemption, upon required repurchase, upon declaration or otherwise; (iii) failure by the Company to comply with Section 4.07, 4.09, 4.10, 4.15 or 5.01 of the Indenture; (iv) failure by the Company for 60 days after notice to comply with any of its other agreements in the Indenture or the Notes; (v) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or guarantee now exists or is created after the Initial Issuance Date, if such default (a) is caused by a failure to pay principal of, or premium or interest, if any, on such Indebtedness prior to the expiration of any grace period provided in such Indebtedness (a “Payment Default”) or (b) results in the acceleration of such Indebtedness prior to its Stated Maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates in excess of $50.0 million; (vi) failure by the Company or any of its Subsidiaries to pay final judgments aggregating in excess of $50.0 million, which judgments are not paid, discharged or stayed (including a stay pending appeal) for a period of 60 days after the date of such final judgment (or, if later, the date when payment is due pursuant to such judgment); (vii) except as permitted by the Indenture, any Subsidiary Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Subsidiary Guarantee; and (viii) certain events of bankruptcy, insolvency or reorganization with respect to the Company, any Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary as specified in Section 6.01(h) or 6.01(i) of the Indenture. If any Event of Default occurs and is continuing, the Trustee, by notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Notes, by notice to the Company and 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 certain events of bankruptcy, insolvency or reorganization with respect to the Company, any Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary described in Section 6.01(h) or 6.01(i) of the Indenture, all outstanding Notes will become due and payable without further action or notice. 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 or premium) if it determines that withholding notice is in their interest. 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 past 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 premium or interest on the Notes or in respect of a covenant that cannot be amended without the consent of each Holder. The Company is required to deliver to

the Trustee annually a statement regarding compliance with the Indenture, and, so long as any Notes are outstanding, the Company is required upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

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

     14. Subordination.

Each Holder of this Note, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee his attorney-in-fact for any and all such purposes.

     15. No Recourse Against Others. No past, present or future director, officer, employee, incorporator, member, partner or stockholder or other owner of Capital Stock 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 Guarantees or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation.
