Capitalized terms used and not otherwise defined herein have their respective meanings set for the Agreement and Plan of Merger by and among Parent, Purchaser, Badlands Energy, LLC, a North Dakota limited liability company (the “Company”) and Mark D. Johnsrud (the “Seller”) (as may be amended or modified from time to time, the “Merger Agreement”).

W I T N E S S E T H:

WHEREAS, concurrently herewith, Parent, Purchaser, Seller and the Company are entering into the Merger Agreement pursuant to which, at the Effective Time, Purchaser will be merged with and into the Company, following which the Purchaser shall continue as the Surviving Company (the “Merger”);

WHEREAS, as of the date hereof, each Principal Stockholder owns beneficially or of record or has the power to vote, or direct the vote of, the number of shares of common stock, par value $0.001 per share, of Parent (the “Parent Company Stock”) as set forth opposite such Principal Stockholder’s name on Exhibit A hereto (all such Parent Company Stock and any shares of Parent Company Stock of which ownership of record or beneficially or the power to vote is hereafter acquired by the Principal Stockholders prior to the termination of this Agreement being referred to herein as the “Shares”);

WHEREAS, the member, manager or board of directors of the Purchaser and Parent, as applicable, have adopted resolutions adopting, approving and declaring advisable the Merger Agreement and transactions contemplated thereby;

WHEREAS, in accordance with Rule 312.03 of the New York Stock Exchange, the approval of the stockholders of Parent is required by a majority of votes cast at a meeting of stockholders for the issuance of a number of shares of Parent Company Stock pursuant to the Merger Agreement that will be upon issuance equal to or in excess of twenty percent (20%) of the number of shares of Parent Company Stock outstanding before such issuance (the “Parent Stockholder Approval”);

WHEREAS, as soon as practicable after the date of the Merger Agreement, Parent shall (i) file a preliminary proxy statement relating to the solicitation of proxies from the stockholders of Parent for the Parent Stockholder Approval and (A) respond promptly to any comments made by the SEC with respect to the preliminary proxy statement and promptly cause a definitive proxy statement to be mailed to Parent’s stockholders and (B) solicit proxies from its stockholders for the Parent Stockholder Approval and (ii) cause a special meeting of its stockholders (the “Special Meeting”) to be duly called, noticed and held as promptly as practicable after the date of this Agreement for the purpose of obtaining the Parent Stockholder Approval; and

WHEREAS, as a condition to the willingness of Seller and the Company to enter into the Merger Agreement, Seller and the Company have requested that the Principal Stockholders enter into this Agreement, and, in order to induce Purchaser, Parent, Seller and the Company to enter into the Merger Agreement, the Principal Stockholders have agreed to enter into this Agreement solely in each Principal Stockholder’s capacity as a stockholder of Parent.

NOW, THEREFORE, in consideration of the premises and of the mutual agreements and covenants set forth herein and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, and intending to be legally bound hereby, the parties hereto agree as follows:

ARTICLE I

TRANSFER AND VOTING OF SHARES

SECTION 1.01 Transfer of Shares. No Principal Stockholder shall, directly or indirectly, until the earlier of the termination of this Agreement or when the Parent Stockholder Approval is obtained (a) sell, pledge, encumber, assign, transfer, grant an option with respect to or otherwise dispose of any or all of such Principal Stockholder’s Shares or any interest in such Shares, (b) deposit any of such Principal Stockholder’s Shares or any interest in such Shares into a voting trust or enter into a voting agreement or arrangement with respect to any such Shares or grant any proxy with respect thereto (other than as contemplated herein), or (c) enter into any contract, commitment, option or other arrangement or undertaking with respect to the direct or indirect acquisition or sale, assignment, pledge, encumbrance, transfer, option with respect to, or other disposition of any Shares. Notwithstanding the provisions in the previous sentence, prior to the Effective Time, any Principal Stockholder may transfer, sell, exchange, pledge or otherwise dispose of or encumber, Shares (i) to any Affiliate of such Principal Stockholder, provided that each such transferee or assignee, prior to the completion of the transfer, sale, exchange, pledge or encumbrance, shall have executed documents assuming all of the obligations of such Principal Stockholder under this Agreement and shall have executed a proxy in the form attached hereto as Exhibit B (the “Proxy”) with respect to the transferred Shares and (ii) pursuant to a plan in effect as of the date of this Agreement in compliance with Rule 10b5-1 under the Exchange Act.

SECTION 1.02 Grant of Irrevocable Proxy. Concurrently with the execution of this Agreement, each Principal Stockholder agrees to deliver to Purchaser the Proxy, which shall be coupled with an interest and irrevocable to the fullest extent permissible by law. Such Proxy will survive the death, incompetence or disability of such Principal Stockholder. Each Principal Stockholder represents and warrants that any proxies heretofore given in respect of such Principal Stockholder’s Shares that may still be in effect are not irrevocable and that any such proxies are hereby revoked.

SECTION 1.03 Vote in Favor of the Parent Stockholder Approval. If for any reason the Proxy is deemed to be invalid, during the period commencing on the date hereof and terminating at the Effective Time, each Principal Stockholder, solely in such Principal Stockholder’s capacity as a stockholder of Parent, agrees to vote (or cause to be voted) all of his Shares at the Special Meeting, or any adjournment thereof (whether held directly or beneficially and whether now owned or hereafter acquired), in favor of the Parent Stockholder Approval. If a Principal

2

Stockholder is the beneficial owner, but not the record holder, of the Parent Company Stock, such Principal Stockholder agrees to take all commercially reasonable actions necessary to cause the record holder and any nominees to vote all of the Parent Company Stock in favor of the Parent Stockholder Approval.

SECTION 1.04 Termination. This Agreement, the Proxies granted hereunder and the obligations of the Principal Stockholders pursuant to this Agreement shall terminate upon the earliest of (a) the date of the termination of the Merger Agreement pursuant to Article 8 thereof, (b) the date upon which the Board of Directors of the Company approves or recommends a Superior Proposal and (c) the Effective Time.

ARTICLE II

SECTION 2.03 Litigation. With respect to such Principal Stockholder, as of the date hereof, there is no action, suit, investigation or proceeding pending against, or, to the knowledge of such Principal Stockholder, threatened against or affecting, such Principal Stockholder or any of his properties or assets (including the Shares) that could reasonably be expected to impair the ability of such Principal Stockholder to perform his obligations hereunder or to consummate the transactions contemplated hereby on a timely basis.
