Item 4. Purpose of Transaction.

On December 21, 2011, the Issuer entered into a Securities Purchase Agreement (the “Purchase Agreement”) with Halcon Resources, LLC, a Delaware limited liability company (“Halcon”). Pursuant to the Purchase Agreement, (i) Halcon will purchase and the Issuer will sell 220,000,000 shares of the Issuer’s common stock (the “Shares”) for a purchase price of $275,000,000, or $1.25 per share, and (ii) Halcon will purchase at face value and the Issuer will issue a senior convertible promissory note in the principal amount of $275,000,000 (the “Note”), together with five year warrants to purchase 110,000,000 shares of the Issuer’s common stock at an exercise price of $1.50 per share (the “Warrants”). The purchase and sale of the Shares, the Note and the Warrants is referred to herein as the “Securities Purchase”.

The Board of Directors of the Issuer and the members of Halcon have approved the Purchase Agreement and the Securities Purchase. The stockholders filing this Schedule 13D, which hold a majority of the Issuer’s outstanding shares of common stock, have executed a stockholders agreement (the “Stockholders Agreement”) pursuant to which such stockholders agreed to execute and deliver within 20 business days following the execution of the Purchase Agreement, or January 20, 2012, a written consent (the “Stockholder Approval”) approving (i) the issuance of the Shares, the Note and the Warrants pursuant to the terms of the Purchase Agreement; (ii) the amendment of the Issuer’s certificate of incorporation to (A) increase the Issuer’s authorized shares of common stock from 100,000,000 shares to 1,010,000,000 shares; (B) effect a 1-for-3 reverse stock split of the Issuer’s common stock upon satisfaction of the notice requirements of the NASDAQ Stock Market following the closing; and (C) change the name of the Issuer to Halcon Resources Corporation; and (iii) the amendment of the Issuer’s 2006 Long-Term Incentive Plan to increase the number of shares that may be issued under the plan from 7.4 million to 11.1 million shares.

As a condition to closing, the Issuer’s current officers and directors will resign effective as of the closing, although certain Issuer officers may be retained by Halcon for an indefinite period. A new Board of Directors will be immediately appointed by Halcon. Completion of the Securities Purchase is also subject to other customary closing conditions.

Following closing, Halcon has agreed, expressly for the benefit of the Issuer’s stockholders other than Halcon that, for the two year period following the closing date, Halcon will not vote its shares in favor any transactions that would result in the Issuer “going private” such as a “cash-out” or “freeze-out merger,” a more than 1-for-100 reverse stock split or any other transaction that would constitute a transaction regulated by Rule 13e-3 of the Securities Exchange Act of 1934.

The Purchase Agreement contains customary termination rights for both the Issuer and Halcon, including the right of the Issuer or Halcon to terminate the Purchase Agreement in the event that the Issuer accepts a Superior Proposal (as defined in the Purchase Agreement) prior to the date that the stockholders execute and deliver the Stockholder Approval. The Stockholders Agreement will terminate upon termination of the Purchase Agreement.

The Shares, the Note and the Warrants will be issued and sold in a private placement exempt from the registration requirements of the Securities Act of 1933 under Section 4(2) of the Securities Act of 1933. At closing, the Issuer will enter into a registration rights agreement with Halcon which will give Halcon the right to require the Issuer, on up to three occasions, to register for public sale the Shares acquired at the closing and any shares of common stock acquired upon the exercise of the Warrants and conversion of the Note. The registration rights agreement will also provide Halcon with piggyback registration rights with respect to registrations of the offer and sale of any shares of the Issuer’s common stock the Issuer may effect for its own account or for the benefit of other selling stockholders.

Item 5. Interest in Securities of the Issuer.

Jefferies & Company, Inc.

Jefferies has a service agreement with Trading, pursuant to which Trading has granted to Jefferies the power to vote or direct the vote, and to dispose or to direct the disposition of, the shares of Common Stock reported herein and held for the account of Trading, and, accordingly, Jefferies may be deemed to beneficially own the shares of Common Stock reported herein which are held for the account of Trading. Holdings is the sole owner of Trading, and, in such capacity, may be deemed to beneficially own the shares of Common Stock reported herein which are held for the account of Trading. Jefferies Group is the sole owner of Jefferies and a member of Holdings, and, in such capacities, may be deemed to beneficially own the shares of Common Stock reported herein which are held for the accounts of Jefferies and Holdings.

The filing of this amendment shall not be construed as an admission that Jefferies, Trading, Holdings, or Jefferies Group is, for purposes of Section 13 of the Act, the beneficial owner of any shares not held directly for the account of each such Jefferies Reporting Person covered by this Schedule 13D.

Brian P. Friedman who beneficially owns shares of Issuer common stock may be considered an affiliate of the Jefferies Reporting Persons for purposes of Section 13 of the Act and the Jefferies Reporting Persons may be deemed to beneficially own the shares of Issuer common stock beneficially owned by Mr. Friedman. Mr. Friedman and each of the Jefferies Reporting Persons may coordinate their decisions or actions relating to the holding, voting and/or disposition of the shares of Issuer common stock beneficially owned by each such person. Each of the Jefferies Reporting Persons expressly disclaims (a) beneficial ownership of the shares of Issuer common stock beneficially owned by Mr. Friedman and (b) that the Jefferies Reporting Persons and Mr. Friedman constitute a “group” or “person” for purposes of Section 13 of the Act.

Amount Beneficially Owned:

As of the date hereof:

Percentage of Class:

The calculations set forth herein are based on 78,768,405 shares of Issuer common stock outstanding. This number was reported as outstanding on December 21, 2011 by the Issuer.

Exhibit 10.3

STOCKHOLDERS AGREEMENT

This Stockholders Agreement (the “Agreement”) is made and entered into this 21st day of December, 2011, by and among RAM ENERGY RESOURCES, INC., a Delaware corporation (the “Company”), HALCON RESOURCES, LLC, a Delaware limited liability company (“Halcon”), and the undersigned stockholders of the Company (the “Stockholders”).

RECITALS

WHEREAS, the Company and Halcon have entered into a Securities Purchase Agreement of even date herewith (the “Purchase Agreement”) that provides, among other things, for the purchase by Halcon from the Company of shares of common stock, par value $.0001 per share, of the Company (“Common Stock”), as well as Warrants and a Note that will be exercisable for or convertible into additional shares of Common Stock; and

WHEREAS, the Stockholders currently own, of record and beneficially, and control a majority of the outstanding shares of Common Stock and, in order to induce Halcon to enter into the Purchase Agreement and to consummate the transactions contemplated thereby, the Stockholders desire to agree to approve such transactions and to take certain additional actions as set forth herein; and

WHEREAS, each of the Stockholders has read and understands the terms and provisions of the Purchase Agreement and the effects of the consummation of the transactions contemplated thereby, including but not limited to the dilution of their individual and collective ownership interests in the Company; and

WHEREAS, the parties are entering into this Agreement as a condition to the execution of the Purchase Agreement.

NOW, THEREFORE, in consideration of the mutual promises contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Stockholder Voting. Each of the Stockholders agrees, so long as it owns or controls such shares, to vote the shares of Common Stock owned, of record and beneficially, by such Stockholder as set forth on Exhibit A attached hereto (the “Stock”) to approve the issuance of the Securities pursuant to the terms and conditions of the Purchase Agreement and each of the following items (such issuance and other items, collectively, the “Proposed Actions”):

Without limiting the foregoing, each Stockholder agrees to execute and deliver to the Company, not later than twenty (20) Business Days after the date hereof, a written consent, in a form reasonably acceptable to Halcon (the “Written Consent”), evidencing the affirmative vote of all of the Stock owned and controlled by such Stockholder to approve each of the Proposed Actions. The Stockholders understand and agree that their covenants and agreements set forth herein are irrevocable for so long as this Agreement remains in effect. Each Stockholder agrees not to revoke, rescind or supersede, or to vote any of its Stock in any manner contrary to, its approval of the Proposed Actions given pursuant to the Written Consent or at any meeting of stockholders. The preceding sentence shall survive any termination of this Agreement pursuant to clause (ii) or (iii) of Section 2 below until the Purchase Agreement is terminated in accordance with its terms or the transactions contemplated by the Purchase Agreement are consummated.

2. Term. This Agreement shall terminate and be of no further force and effect upon the first to occur of (i) termination of the Purchase Agreement, (ii) the delivery to the Company of the Written Consent executed by all of the Stockholders, or (iii) the date of any meeting of the Company’s stockholders, whereby the issuance of the Securities pursuant to the Purchase Agreement and the other Proposed Actions are voted upon.

3. Stockholders’ Representation and Warranties. Each Stockholder severally, as to itself only, represents and warrants to Halcon that (a) such Stockholder has duly authorized, executed and delivered this Agreement and this Agreement constitutes a valid and binding agreement, enforceable in accordance with its terms, and neither the execution and delivery of this Agreement nor the consummation by the Stockholder of the transactions contemplated hereby will constitute a violation of, a default under, or conflict with any contract, commitment, agreement, understanding, arrangement or restriction of any kind to which the Stockholder is a party or by which the Stockholder is bound; (b) consummation by such Stockholder of the transactions contemplated hereby will not violate, or require any consent, approval, or notice under, any provision of law other than filing on Schedule 13D that may be required under the Securities Exchange Act of 1934, as amended; (c) except to the extent contemplated herein, such Stockholder’s shares of Stock and the certificates representing such shares are now and at all times during the term of this Agreement will be held by the Stockholder, or by a nominee or custodian for the benefit of the Stockholder, free and clear of all liens, claims, security interests, proxies, voting trusts or agreements or any other encumbrances whatsoever (“Encumbrances”) with respect to the ownership or voting of such

shares of Stock or otherwise, other than Encumbrances created by or arising pursuant to this Agreement; (d) there are no outstanding options, warrants or rights to purchase or acquire, or proxies, powers-of-attorney, voting agreements, trust agreements or other agreements relating to, such shares of Stock other than this Agreement; and (e) such Stockholder has the present power and right to vote all the shares of Stock as contemplated herein.

4. Certain Defined Terms. Unless otherwise expressly provided herein, all capitalized terms used herein without definition shall have the meanings assigned to them in the Purchase Agreement.

5. Negative Covenants of Each Stockholder. Except to the extent contemplated herein or in the Purchase Agreement, each Stockholder hereby covenants and agrees that, during the term of this Agreement, such Stockholder will not, and will not agree to, directly or indirectly, (a) sell, transfer, assign, cause to be redeemed or otherwise dispose of any of its shares of Stock or enter into any contract, option or other agreement or understanding with respect to the sale, transfer, assignment, redemption or other disposition of its shares of Stock; (b) grant any proxy, power-of-attorney or other authorization or interest in or with respect to its shares of Stock pertaining or relating to the Purchase Agreement, any of the transactions contemplated thereby or any of the other Proposed Actions; or (c) deposit such Stock into a voting trust or enter into a voting agreement or arrangement with respect to such Stock, unless and until, in the case of clause (a), (b) or (c) above, the Stockholder shall have taken all actions (including, without limitation, the placement of a legend on the certificates evidencing such Stock) reasonably necessary to ensure that such Stock shall at all times be subject to all the rights, powers and privileges granted or conferred, and subject to all the restrictions, covenants and limitations imposed, by this Agreement and shall have caused, as a condition to any sale, transfer, pledge or other disposition of any shares of Stock, any transferee of any of the Stock, unless it is already a signatory to this Agreement, to become a signatory to and be bound by the terms of this Agreement.

6. Remedies and Liability for Breach. The Stockholders agree that, to the extent permitted by law, (i) the obligations imposed on them in this Agreement are special, unique and of an extraordinary character, and that in the event of a breach by any Stockholder, damages would not be an adequate remedy, and (ii) Halcon shall be entitled to specific performance and injunctive and equitable relief in addition to any other remedy to which it may be entitled at law or in equity.

7. Successors. This Agreement shall be binding upon and shall operate for the benefit of Halcon, the Stockholders and the Company, their respective members and stockholders, and their respective successors, assigns, executors, administrators and heirs, and it shall be binding upon any entity to whom any Stock is transferred whether or not in accordance with the provisions of this Agreement, and the executor or administrator of such entity.

8. Modification. Notwithstanding anything to the contrary in this Agreement or otherwise, no modification, amendment or waiver of any of the provisions of this Agreement shall be effective unless in writing and signed by all parties hereto. Each Stockholder covenants not to vote any shares of Stock in favor of any amendment of the certificate of

incorporation or bylaws of the Company, if such amendment would materially modify the terms or frustrate the purpose of this Agreement or the Purchase Agreement, unless the vote on such amendment is approved unanimously by the parties to this Agreement.

9. Non-Waiver. The failure to enforce at any time any of the provisions of this Agreement, or to require at any time performance by any other party of any of the provisions hereof, shall in no way be construed to be a waiver of such provisions.

10. Invalid Provisions. If any provision of this Agreement is held to be illegal, invalid, or unenforceable under present or future Laws effective during the term hereof, such provision shall be fully severable, this Agreement shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part hereof, and the remaining provisions hereof shall remain in full force and effect and shall not be affected by the illegal, invalid, or unenforceable provision or by its severance herefrom.

11. Entire Agreement. This Agreement and the Purchase Agreement contain the full understanding of the parties hereto with respect to the subject matter hereof, and there are no representations, warranties, agreements or understandings other than expressly contained herein or therein.

12. Notices. Any notice to be given by any party hereunder to any other shall be in writing, mailed by certified or registered mail, return receipt requested, and shall be addressed to all other parties at the addresses listed on the signature page hereof. All such notices shall be deemed to be given three (3) days after the date of mailing thereof.

13. Governing Law. THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF DELAWARE.

14. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute but one and the same instrument.
