SUBJECT TO COMPLETION, DATED MAY 31, 2006 PROSPECTUS 12,650,000 Shares RAM Energy Resources, Inc. Common Stock $5.00 per share --------- This prospectus relates to an aggregate of 12,650,000 shares of common stock, $0.0001 par value, that may be issued upon the exercise of outstanding warrants. In connection with the sale of the warrants, we agreed to register the shares of common stock issuable upon exercise of the warrants. Each warrant entitles the holder, upon exercise, to purchase one share of our common stock at a price of $5.00 per share. Our common stock is quoted on the Nasdaq Capital Market under the symbol RAME. Our offices are located at 5100 East Skelly Drive, Suite 650, Tulsa, Oklahoma 74135, and our telephone number is (918) 663-2800. You should read this prospectus and any prospectus supplement before you invest. Total(1) Per Share(1) ----------- ------------ Price $63,250,000 $5.00 Underwriter's Discounts and Commissions $ 0(2) $ 0(2) Net Proceeds $63,222,000 $5.00 ------------------------- (1) These amounts presume that all warrants are exercised. (2) We have engaged EarlyBirdCapital, Inc., or EBC, on a non-exclusive basis, as our agent for the solicitation of the exercise of the warrants. Subject to certain circumstances, we will pay EBC a commission of five percent of the exercise price of the warrants, or $.25 per share, for each warrant exercised, payable on the date of such exercise. The amounts above assume that EBC did not solicit any exercises of warrants. If EBC otherwise solicited fifty percent (50%) of the exercises of the warrants, and assuming that all warrants were exercised, total commissions would be $1,581,250 (or $.125 per share), and net proceeds would be $61,640,750 (or $4.875 per share). If EBC otherwise solicited all of the exercises of the warrants, and assuming that all warrants were exercised, total commissions would be $3,162,500 (or $.25 per share), and net proceeds would be $60,059,500 (or approximately $4.75 per share). See "Use of Proceeds" for a description of our engagement with EBC. --------- Investing in the shares involve risks.

PROSPECTUS SUMMARY You should read the following summary together with the more detailed information and financial statements that we incorporate by reference and related notes appearing elsewhere in this prospectus. Unless the context otherwise requires, all references in this prospectus to "RAM Energy Resources," "our," "us," and "we" refer to RAM Energy Resources, Inc. (formerly known as Tremisis Energy Acquisition Corporation) and its subsidiaries, as a combined entity, except where it is clear that such term means only RAM Energy Resources, Inc. All references in this prospectus to "RAM" refer to RAM Energy, Inc., our wholly owned subsidiary. Unless the context otherwise requires, the information contained in this prospectus gives effect to the May 8, 2006 consummation of the merger of RAM Energy Acquisition, Inc., our wholly owned subsidiary, with and into RAM Energy, Inc., and the change of our name from Tremisis Energy Acquisition Corporation to RAM Energy Resources, Inc., which transactions are collectively called the "merger." References to "pro forma" with respect to our results of operations reflect adjustments to our historical financial statements as if the merger had occurred as of January 1, 2006. References to "pro forma" with respect to our financial condition reflect adjustments to our historical financial statements as if the merger had been completed as of March 31, 2006. A summary of the business and operations of RAM Energy Resources is included in our proxy statement filed with the Commission on April 18, 2006, which is incorporated herein by reference, and our Current Report on Form 8-K filed with the Commission on May 12, 2006, which is incorporated herein by reference. Our offices are located at 5100 East Skelly Drive, Suite 650, Tulsa, Oklahoma 74135, and our telephone number is (918) 663-2800. RISK FACTORS A discussion of the risk factors relating to an investment in us is included in our proxy statement filed with the Commission on April 18, 2006, which is incorporated herein by reference. You should carefully consider the risk factors discussed in the proxy statement, together with all of the other information included in this prospectus, before you decide whether to exercise your warrants. FORWARD-LOOKING STATEMENTS We believe that some of the information in this prospectus constitutes forward-looking statements within the definition of the Private Securities Litigation Reform Act of 1995. You can identify these statements by forward-looking words such as "may," "expect," "anticipate," "contemplate," "believe," "estimate," "intends," and "continue" or similar words. You should read statements that contain these words carefully because they: o discuss future expectations; o contain projections of future results of operations or financial condition; or o state other "forward-looking" information. We believe it is important to communicate our expectations to our stockholders. However, there may be events in the future that we are not able to predict accurately or over which we have no control. The risk factors and cautionary language discussed in our proxy statement, which is incorporated herein by reference, provide examples of risks, uncertainties and events that may cause actual results to differ materially from the expectations described by us in such forward-looking statements, including among other things: o outcomes of government reviews, inquiries, investigations and related litigation; o continued compliance with government regulations; o legislation or regulatory environments, requirements or changes adversely affecting the business in which we are engaged; o fluctuations in customer demand; o management of rapid growth; o general economic conditions; o our business strategy and plans; o the actual quantities of our reserves of oil and natural gas; o the future levels of production of oil and natural gas by us; o future prices of and demand for oil and natural gas; o the results of our future exploration, development and exploitation activities; o future operating and development costs of our oil and natural gas properties; and o the results of future financing efforts. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this prospectus. USE OF PROCEEDS The amount of the proceeds we will receive from the shares covered by this prospectus depends on the number of warrants exercised. Subject to the discussion below, if all of the warrants are exercised, our gross proceeds from the sale of the shares of common stock pursuant to the exercise of the warrants will be $63,250,000. We expect net proceeds, which are what we will receive after paying the estimated expenses of this offering, to be approximately $63,222,000. For the purpose of estimating net proceeds, we are assuming that the offering price will be $5.00 per share, which is the exercise price of the warrants. We have engaged EarlyBirdCapital, Inc., or EBC, on a non-exclusive basis, as our agent for the solicitation of the exercise of the warrants. We will (i) assist EBC with respect to such solicitation, if requested by EBC, and (ii) at EBC's request, provide EBC, and direct our transfer and warrant agent to provide to EBC, at our cost, lists of the record and, to the extent known, beneficial owners of, the warrants. We will pay EBC a commission of five percent of the exercise price of the warrants, or $.25, for each warrant exercised, payable on the date of such exercise, on the terms provided for in the warrant agreement, but only if permitted under the rules and regulations of the NASD and only to the extent that a warrant holder who exercises a warrant specifically designates, in writing, that EBC solicited the exercise. EBC may engage sub-agents in its solicitation efforts. If EBC otherwise solicited fifty percent (50%) of the exercises of the warrants, and assuming that all warrants were exercised, total commissions would be $1,581,250, and net proceeds would be approximately $61,640,750. If EBC otherwise solicited all of the exercises of the warrants, and assuming that all warrants were exercised, total commissions would be $3,162,500, and net proceeds would be $60,059,500. We intend to use the net proceeds for working capital, to pay down our revolver under our secured credit facility or for other general corporate purposes. DETERMINATION OF OFFERING PRICE The offering price for the shares covered by this prospectus is the exercise price of the warrants, which was determined at the time the warrants were issued. DIVIDEND POLICY We currently intend to retain all of our earnings to finance our operations, repay indebtedness and fund our future growth. We do not expect to pay any dividends on our common stock for the foreseeable future. In addition, covenants contained in the instrument governing our secured credit facility limit our ability to pay dividends on our common stock. LEGAL MATTERS McAfee & Taft A Professional Corporation, Oklahoma City, Oklahoma, will issue an opinion to us about certain legal matters relating to the securities. C. David Stinson is a shareholder with the law firm of McAfee & Taft A Professional Corporation, which provided the opinion in connection with the securities being registered by this registration statement. Mr. Stinson owns 489,626 shares of our common stock. EXPERTS The consolidated financial statements of RAM Energy, Inc. at December 31, 2005 and 2004, and for each of the three years in the period ended December 31, 2005, incorporated by reference in this registration statement, have been audited by UHY Mann Frankfort Stein & Lipp CPAs, LLP, independent registered public accounting firm, as set forth in their report appearing in the proxy statement pursuant to Section 14(a) of the Securities Exchange Act of 1934 filed on April 18, 2006, and are incorporated herein by reference in reliance upon such report given on the authority of such firm as experts in accounting and auditing. The financial statements of RAM Energy Resources, Inc. (formerly known as Tremisis Energy Acquisition Corporation) at December 31, 2005 and 2004, the year ended December 31, 2005, the period from February 5, 2004 (inception) to December 31, 2004, and the period from February 5, 2004 (inception) to December 31, 2005, incorporated by reference in this registration statement, have been audited by BDO Seidman, LLP, independent registered public accounting firm as set forth in their report (which contains an explanatory paragraph regarding the Company's ability to continue as a going concern) appearing in the proxy statement pursuant to Section 14(a) of the Securities Exchange Act of 1934 filed on April 18, 2006, and are incorporated herein by reference in reliance upon such report given on the authority of such firm as experts in accounting and auditing. Certain estimates of oil and natural gas reserves incorporated herein by reference to the proxy statement (No. 000-50682) pursuant to Section 14(a) of the Securities Exchange Act of 1934 filed on April 18, 2006, were based upon engineering studies prepared by Williamson Petroleum Consultants, Inc., independent petroleum engineers, and Forrest A. Garb & Associates, Inc., independent petroleum engineers. Each such estimate is incorporated by reference herein in reliance on the authority of each of the respective firms as an expert in such matters. See Appendix A and Appendix B. INDEMNIFICATION Section 145 of the Delaware General Corporation Law, under which we are incorporated, grants each corporation organized thereunder the power to indemnify any person who is or was a director, officer, employee or agent of a corporation or enterprise, against expenses, including attorney's fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of the corporation, by reason of being or having been in any such capacity, if he acted in good faith in a manner reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. Article Eighth of our Amended and Restated Certificate of Incorporation, as well as Article VII of our Bylaws, provide indemnification of directors, officers and agents to the extent permitted by the Delaware General Corporation Law. These provisions may be sufficiently broad to indemnify such persons for liabilities under the Securities Act of 1933. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is therefore unenforceable. PLAN OF DISTRIBUTION The securities covered by this prospectus will be distributed solely to existing warrantholders upon exercise of their warrants. The warrants are immediately exercisable as of the effective date of the registration statement. The shares of common stock issued upon exercise of the warrants will be freely tradable, except that sales by warrantholders who are our affiliates will be subject to Rule 144 as promulgated under the Securities Act. We do not know if or when the warrants will be exercised. We also do not know whether any of the shares acquired upon exercise will be sold. DESCRIPTION OF SECURITIES The description of the securities covered by this prospectus is contained in our proxy statement filed April 18, 2006, which is incorporated herein by reference.

Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is a part of the registration statement. (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
