Execution Version

THIS VOTING AGREEMENT (this “Agreement”), is dated as of April 24, 2012 by and among Halcón Resources Corporation, a Delaware corporation (“Parent”), Leopard Sub I, Inc., a Colorado corporation and wholly owned subsidiary of Parent (“Merger Sub”), and each of the Persons listed on Schedule A hereto (each a “Stockholder” and, collectively, the “Stockholders”).

WHEREAS, each of the Stockholders is, as of the date hereof, the record and beneficial owner of that number of shares of Common Stock, par value $0.01 per share (the “Company Common Stock”), of GeoResources, Inc., a Colorado corporation (the “Company”), set forth opposite such Stockholder’s name on Schedule A hereto;

WHEREAS, Parent, Merger Sub and the Company concurrently with the execution and delivery of this Agreement are entering into an Agreement and Plan of Merger, dated as of the date hereof (as the same may be amended or supplemented, the “Merger Agreement”), providing for, among other things, the merger (the “Merger”) of Merger Sub with and into the Company, and the Company as the surviving entity to the Merger thereafter merging with and into Leopard Sub II, LLC, a Delaware limited liability company and wholly owned subsidiary of Parent, upon the terms and subject to the conditions set forth in the Merger Agreement (capitalized terms used and not otherwise defined herein shall have the meanings attributed thereto in the Merger Agreement); and

WHEREAS, as a condition to the willingness of Parent and Merger Sub to enter into the Merger Agreement, and in order to induce Parent and Merger Sub to enter into the Merger Agreement, the Stockholders have agreed to enter into this Agreement.

NOW, THEREFORE, in consideration of the execution and delivery by Parent and Merger Sub of the Merger Agreement and the mutual representations, warranties, covenants and agreements contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

Section 1. Representations and Warranties of the Stockholders. Each of the Stockholders hereby represents and warrants to Parent and Merger Sub, severally and not jointly, as follows:

(a) Such Stockholder is the beneficial owner (within the meaning of Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) and unless otherwise indicated, the record owner of the shares of Company Common Stock (as may be adjusted from time to time pursuant to Section 5 hereof, the “Shares”) set forth opposite such Stockholder’s name on Schedule A to this Agreement and such Shares represent all of the shares of Company Common Stock beneficially owned by such Stockholder as of the date hereof. For purposes of this Agreement, the term “Shares” shall include any shares of Company Common Stock issuable to such Stockholder upon exercise or

conversion of any existing right, contract, option, or warrant to purchase, or securities convertible into or exchangeable for, Company Common Stock (“Stockholder Rights”) that are currently exercisable or convertible or become exercisable or convertible and any other shares of Company Common Stock such Stockholder may acquire or beneficially own during the term of this Agreement.

(b) Such Stockholder has all requisite power and authority and, if an individual, the legal capacity, to execute and deliver this Agreement and to consummate the transactions contemplated hereby. This Agreement has been validly executed and delivered by such Stockholder and, assuming that this Agreement constitutes the legal, valid and binding obligation of the other parties hereto, constitutes the legal, valid and binding obligation of such Stockholder, enforceable against such Stockholder in accordance with its terms (except insofar as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally, or by principles governing the availability of equitable remedies).

(c) The execution and delivery of this Agreement by such Stockholder does not, and the performance of this Agreement by such Stockholder will not, (i) conflict with the certificate of incorporation or bylaws or similar organizational documents of such Stockholder as presently in effect (in the case of a Stockholder that is a legal entity), (ii) conflict with or violate any judgment, order, decree, statute, Law, ordinance, rule or regulation applicable to such Stockholder or by which it is bound or affected, (iii)(A) result in any breach of or constitute a default (or an event that with notice or lapse of time or both would become a default) under, (B) give to any other Person any rights of termination, amendment, acceleration or cancellation of, or (C) result in the creation of any pledge, claim, lien, charge, encumbrance or security interest of any kind or nature whatsoever upon any of the properties or assets of the Stockholder under, any agreement, contract, indenture, note or instrument to which such Stockholder is a party or by which it is bound or affected, except for such breaches, defaults or other occurrences that would not prevent or materially delay the performance by such Stockholder of any of such Stockholder’s obligations under this Agreement, or (iv) except for applicable requirements, if any, of the Exchange Act, the Securities Act of 1933, as amended (the “Securities Act”), the New York Stock Exchange (the “NYSE”) or the Xxxx-Xxxxx-Xxxxxx Antitrust Improvements Act of 1976, as amended (the “HSR Act”), require any filing by such Stockholder with, or any permit, authorization, consent or approval of, any governmental or regulatory authority, except where the failure to make such filing or obtain such permit, authorization, consent or approval would not prevent or materially delay the performance by Stockholder of any of such Stockholder’s obligations under this Agreement.

(d) The Shares and the certificates representing the Shares owned by such Stockholder are now and at all times during the term hereof will be held by such Stockholder, or by a nominee or custodian for the benefit of such Stockholder, free and clear of all pledges, liens, charges, claims, security interests,

proxies, voting trusts or agreements, understandings or arrangements or any other encumbrances whatsoever, except for any such encumbrances or proxies arising hereunder or under applicable federal and state securities laws or under the agreements set forth on Schedule B hereto. Such Stockholder owns of record or beneficially no shares of Company Common Stock other than such Stockholder’s Shares.

(e) As of the date hereof, neither such Stockholder, nor any of its respective properties or assets is subject to any order, writ, judgment, injunction, decree, determination or award that would prevent or delay the consummation of the transactions contemplated hereby.

(f) Such Stockholder understands and acknowledges that Parent is entering into, and causing Merger Sub to enter into, the Merger Agreement in reliance upon the Stockholder’s execution and delivery of this Agreement.

Section 2. Representations and Warranties of Parent and Merger Sub. Parent and Merger Sub hereby jointly and severally represent and warrant to the Stockholders as follows:

(a) Each of Parent and Merger Sub is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation. Each of Parent and Merger Sub has all requisite power and authority to execute and deliver this Agreement, to perform its obligations hereunder and to consummate the transactions contemplated hereby, and has taken all necessary corporate action to authorize the execution, delivery and performance of this Agreement. This Agreement has been duly executed and delivered by each of Parent and Merger Sub and, assuming that this Agreement constitutes the legal, valid and binding obligation of the other parties hereto, constitutes the legal, valid and binding obligation of each of Parent and Merger Sub, enforceable against each of them in accordance with its terms (except insofar as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally, or by principles governing the availability of equitable remedies).

(b) The execution and delivery of this Agreement by each of Parent and Merger Sub does not, and the performance of this Agreement by each of Parent and Merger Sub will not, (i) conflict with the certificate of incorporation or bylaws or similar organizational documents of each of Parent and Merger Sub as presently in effect, (ii) conflict with or violate any judgment, order, decree, statute, Law, ordinance, rule or regulation applicable to Parent or Merger Sub or by which either is bound or affected, (iii) (A) result in any breach of or constitute a default (or an event that with notice or lapse of time or both would become a default) under, (B) give to any other Person any rights of termination, amendment, acceleration or cancellation of, or (C) result in the creation of any pledge, claim, lien, charge, encumbrance or security interest of any kind or nature whatsoever upon any of the properties or assets of Parent or Merger Sub under,

any agreement, contract, indenture, note or instrument to which Parent or Merger Sub is a party or by which it is bound or affected, except for such breaches, defaults or other occurrences that would not prevent or materially delay the performance by Parent or Merger Sub of their obligations under this Agreement, or (iv) except for applicable requirements, if any, of the Exchange Act, the Securities Act, the NYSE or the HSR Act, require any filing by Parent or Merger Sub with, or any permit, authorization, consent or approval of, any governmental or regulatory authority, except where the failure to make such filing or obtain such permit, authorization, consent or approval would not prevent or materially delay the performance by Parent or Merger Sub of their obligations under this Agreement.

(c) As of the date hereof, neither Parent or Merger Sub, nor any of their respective properties or assets is subject to any order, writ, judgment, injunction, decree, determination or award that would prevent or delay the consummation of the transactions contemplated hereby.

Section 3. Covenants of the Stockholders. Each of the Stockholders, severally and not jointly, agrees as follows:

(a) Such Stockholder shall not, except as contemplated by the terms of this Agreement, and except for the pledge set forth in Schedule B, sell, transfer, pledge, assign or otherwise dispose of, or enter into any contract, option or other arrangement (including any profit-sharing arrangement) or understanding with respect to the sale, transfer, pledge, assignment or other disposition of, the Shares (including any options or warrants to purchase Company Common Stock) to any Person other than Merger Sub or Merger Sub’s designee (any such action, a “Transfer”). For purposes of clarification, the term “Transfer” shall include, without limitation, any short sale (including any “short sale against the box”), pledge, transfer, and the establishment of any open “put equivalent position” within the meaning of Rule 16a-1(h) under the Exchange Act. Notwithstanding the foregoing, (i) Transfers of Shares as bona fide gifts, (ii) distributions of Shares to partners, members, stockholders, subsidiaries, affiliates, affiliated partnerships or other affiliated entities of the undersigned, (iii) Transfers of Shares by will or intestacy, and (iv) Transfers of Shares to (A) the undersigned’s immediate family or (B) a trust, the beneficiaries of which are the undersigned and/or members of the undersigned’s immediate family, shall not be prohibited by this Agreement; provided that in the case of any such transfer or distribution pursuant to clause (i), (ii), (iii) or (iv), each donee or distributee shall execute and deliver to Parent a valid and binding counterpart to this Agreement.

(b) Such Stockholder shall not, except as contemplated by the terms of this Agreement (i) enter into any voting arrangement, whether by proxy, voting agreement, voting trust, power-of-attorney or otherwise, with respect to the Shares or (ii) take any other action that would in any way restrict, limit or interfere with the performance of his/her obligations hereunder or the transactions contemplated hereby or make any representation or warranty of such Stockholder herein untrue or incorrect in any material respect.

(c) Until the Merger is consummated or this Agreement is terminated, except to the extent specifically permitted by the Merger Agreement, such Stockholder shall not, and shall use its reasonable best efforts to cause any investment banker, financial adviser, attorney, accountant or other representative or agent of such Stockholder not to, directly or indirectly (i) solicit, initiate, encourage or facilitate any inquiries or the making or submission of any proposal or offer that constitutes, or could reasonably be expected to lead to, an Acquisition Proposal, or (ii) participate or engage in any discussions or negotiations with, or disclose any material nonpublic information relating to the Company or any of its Subsidiaries, or otherwise cooperate with any Person concerning an Acquisition Proposal, except to notify such Person as to the existence of this Agreement. Such Stockholder shall immediately terminate, and shall use its reasonable best efforts to cause its affiliates to terminate, any existing discussions or negotiations with any Persons (other than Parent) that could be reasonably expected to lead to an Acquisition Proposal. Such Stockholder shall as promptly as practicable (and in any event within 24 hours) advise Parent of any request for information or inquiry with respect to any Acquisition Proposal or of any Acquisition Proposal, and within 24 hours of the receipt thereof, provide to Parent copies of any written materials received in connection with any of the foregoing, and the identity of the Person making any such Acquisition Proposal or such request or inquiry and shall keep Parent reasonably informed of the status of any Acquisition Proposal, and shall provide to Parent within 24 hours of receipt thereof all written materials received by it with respect thereto. The Shareholder may satisfy its obligation to provide notice and information to Parent with respect to an Acquisition Proposal by arranging for the Company to provide that information to Parent.

(d) At any meeting of Stockholders of the Company called to vote upon the Merger, the Merger Agreement or any other transaction contemplated by the Merger Agreement or at any adjournment thereof or in any other circumstances upon which a vote, consent or other approval (including by written consent) with respect to such matters is sought, each Stockholder shall vote (or cause to be voted), or shall consent, execute a consent or cause to be executed a consent in respect of, such Stockholder’s Shares in favor of the Merger, the adoption by the Company of the Merger Agreement and the approval of any other transactions contemplated by the Merger Agreement. At any meeting of Stockholders of the Company or at any adjournment thereof or in any other circumstances upon which the Stockholder’s vote, consent or other approval is sought, such Stockholder shall vote (or cause to be voted) such Stockholder’s Shares against (i) any merger agreement or merger (other than the Merger Agreement and the Merger), consolidation, combination, sale of substantial assets, reorganization, recapitalization, dissolution, liquidation or winding up of or by the Company or any other Acquisition Proposal with respect to the Company (collectively, “Alternative Transactions”) or (ii) any amendment of the

Company’s articles of incorporation or bylaws or other proposal, action or transaction involving the Company or any of its Subsidiaries, which amendment or other proposal, action or transaction would in any manner impede, frustrate, prevent or nullify the Merger, the Merger Agreement or any of the other transactions contemplated by the Merger Agreement (collectively, “Frustrating Transactions”).

(e) Such Stockholder agrees to permit Parent and Merger Sub to publish and disclose in the Proxy Statement and related filings under the securities laws such Stockholder’s identity and ownership of Shares and the nature of its commitments, arrangements and understandings under this Agreement and any other information required by applicable Law.

Section 4. Grant of Irrevocable Proxy; Appointment of Proxy.

(a) Each Stockholder hereby irrevocably grants to, and appoints, Xxxxx X. Xxxxxx, and any other individual who shall hereafter be designated by Parent, such Stockholder’s proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead of such Stockholder, to vote such Stockholder’s Shares, or grant a consent or approval in respect of such Shares, at any meeting of Stockholders of the Company or at any adjournment thereof or in any other circumstances upon which their vote, consent or other approval is sought, in favor of the Merger, the adoption by the Company of the Merger Agreement and the approval of the other transactions contemplated by the Merger Agreement and against any Alternative Transaction or Frustrating Transaction.

(b) Each Stockholder represents that any proxies heretofore given in respect of such Stockholder’s Shares are not irrevocable, and that any such proxies are hereby revoked.

(c) Each Stockholder hereby affirms that the irrevocable proxy set forth in this Section 4 is given in connection with the execution of the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of such Stockholder under this Agreement. Such Stockholder hereby further affirms that the irrevocable proxy is coupled with an interest and may under no circumstances be revoked, subject to Section 7 herein. Such Stockholder hereby ratifies and confirms all that such irrevocable proxy may lawfully do or cause to be done by virtue hereof. Such irrevocable proxy is executed and intended to be irrevocable in accordance with applicable Law (including the provisions of Section 0-000-000 of the Colorado Business Corporation Act). Such irrevocable proxy shall be valid until the termination of this Agreement pursuant to Section 7 herein.

Section 5. Adjustments Upon Share Issuances, Changes in Capitalization. In the event of any change in Company Common Stock or in the number of outstanding shares of Company Common Stock by reason of a stock dividend, subdivision, reclassification, recapitalization, split, combination, exchange of shares or other similar

event or transaction or any other change in the corporate or capital structure of the Company (including, without limitation, the declaration or payment of an extraordinary dividend of cash, securities or other property), and consequently the number of Shares changes or is otherwise adjusted, this Agreement and the obligations hereunder shall attach to any additional shares of Company Common Stock, Stockholder Rights or other securities or rights of the Company issued to or acquired by each of the Stockholders.

Section 6. Further Assurances. Each Stockholder will, from time to time, execute and deliver, or cause to be executed and delivered, such additional or further transfers, assignments, endorsements, consents and other instruments as Parent or Merger Sub may reasonably request for the purpose of effectively carrying out the transactions contemplated by this Agreement and to vest the power to vote such Stockholder’s Shares as contemplated by Section 3 herein.

Section 7. Termination. This Agreement, and all rights and obligations of the parties hereunder, shall terminate upon the earlier of (a) the Effective Time; (b) the date upon which the Merger Agreement is terminated pursuant to Section 7.1 thereof, or (c) with respect to any Stockholder, upon its delivery of written notice of termination to Parent following any amendment to the Merger Agreement to decrease the Merger Consideration or otherwise alter the Merger Agreement in a manner adverse to the Stockholder in any material respect unless such amendment has been consented to by stockholder in writing prior to such amendment. Notwithstanding the foregoing, Sections 7, 8 and 9 shall survive any termination of this Agreement.

Section 8. Action in Stockholder Capacity Only. No Person executing this Agreement who is or becomes during the term hereof a director or officer of the Company makes any agreement or understanding herein in his or her capacity as such director or officer. Each Stockholder signs solely in his or her capacity as the record holder and beneficial owner of, or the trustee of a trust whose beneficiaries are the beneficial owners of, such Stockholder’s Shares and nothing herein shall limit or affect any actions taken by or fiduciary duties of, a Stockholder or any of its affiliates, in his or her capacity as an officer or director of the Company to the extent permitted by the Merger Agreement and applicable law.

Section 9. Miscellaneous.

(a) Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties without the prior written consent of the other parties, except that Merger Sub may assign, in its sole discretion, any or all of its rights, interests and obligations hereunder to Parent or to any direct or indirect wholly owned subsidiary of Parent. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns. Each Stockholder agrees that this Agreement and the obligations of such Stockholder hereunder shall attach to such Stockholder’s Shares and shall be binding upon any Person or entity to which legal or beneficial ownership of such Shares shall pass, whether by operation of law or otherwise, including without limitation such Stockholder’s heirs, guardians, administrators or successors.

(b) Expenses. All costs and expenses incurred in connection with this Agreement and the transactions contemplated thereby shall be paid by the party incurring such expenses.

EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (B) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (C) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (D) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9(h).

(k) Several Liability. Each party to this Agreement enters into this Agreement solely on its own behalf, each such party shall solely be severally liable for any breaches of this Agreement by such party and in no event shall any party be liable for breaches of this Agreement by any other party hereto.

(l) Non-Recourse. No past, present or future director, officer, employee, incorporator, member, partner, stockholder, agent, attorney, representative or affiliate of any Stockholder hereto or of any of their respective affiliates shall have any liability (whether in contract or in tort) for any obligations or liabilities of such party arising under, in connection with or related to this Agreement or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby provided, however, that nothing in this Section (l) shall limit any liability of any Stockholder hereto for its breaches of the terms and conditions of this Agreement.

(m) Waiver. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.
