This SUBSCRIPTION AGREEMENT (this “Agreement”), is executed as of September 24, 2010, to be effective according to Section 1.02(a), by and between Crimson Exploration Inc., a Delaware corporation (the “Company”), and America Capital Energy Corporation, a New York corporation (the “Purchaser”). Certain capitalized terms used herein are defined in Section 7.19 of this Agreement.

RECITALS

WHEREAS, the Company wishes to issue and sell to Purchaser, and Purchaser desires to purchase, (i) shares of the Company’s authorized but unissued shares of common stock, par value US$0.001 per share (the “Common Stock”) and (ii) an option (the “Option”) to acquire a newly created class of preferred stock having the rights and preferences as summarized on Exhibit A (the “Preferred Stock”), in each case on the terms and conditions set forth in this Agreement;

WHEREAS, Purchaser has disclosed to the Company that, while it has no current arrangements, understandings or agreements to do so, Purchaser may from time to time purchase additional shares of the Company’s common stock for investment purposes through open market purchases, negotiated private acquisitions or otherwise.

NOW, THEREFORE, in consideration of the premises, representations, warranties and the mutual covenants contained in this Agreement, the parties agree as follows:

ARTICLE I

THE COMMON SHARES; THE OPTION

Section 1.01 Issuance, Sale and Delivery of Shares to Purchaser.

(a) On the terms and subject to the conditions of this Agreement the Company shall issue and sell to Purchaser, and Purchaser shall purchase from the Company, (i) 4,250,000 shares of the Common Stock (the “Common Shares”) and (ii) the Option to acquire an additional 1,750,000 shares of the Preferred Stock (the “Preferred Shares”) which shall be automatically convertible into a like number of shares of Common Stock as described herein, for an aggregate cash payment of US$21,250,000 (the “Purchase Price”). The Common Shares and the Option will be issued and sold to Purchaser on the Closing Date, and the Purchase Price will be paid on the Closing Date as set forth in Section 1.02.

(b) The Option shall be exercisable in full and not in part by Purchaser for a period beginning on the date of the Closing and ending on and including the 60 calendar days from the Closing Date (the “Exercise Period”). Subject to such additional requirements for exercise as may be set forth in the Option Agreement (as defined below), Purchaser may exercise the Option during the Exercise Period by providing to the Company written notice of exercise in accordance with Section 7.06 together with delivery of a cash payment of US$8,750,000 in immediately available funds to the Deposit Account (as defined in the Deposit Agreement) of the Company. For the avoidance of doubt, after the expiration of the Exercise Period, the Option shall lapse and shall no longer be exercisable by Purchaser. Upon valid exercise of the Option, (i) the Preferred Shares will be deemed issued and sold to Purchaser and (ii) the Company shall promptly issue

and deliver to Purchaser a stock certificate or certificates in definitive form, registered in the name of Purchaser, representing the Preferred Shares (or if such Preferred Shares have automatically converted to shares of Common Stock, such shares of Common Stock), bearing such restrictive legends as may be customarily required under United States securities laws.

Section 1.02 Effectiveness; Closing.

(a) This Agreement shall become effective at the time the conditions to each party’s obligations to consummate the Closing as set forth in Article V have been satisfied or, with respect to such conditions which by their terms must be satisfied at the Closing, the time in which each party is capable of performing such conditions.

(b) The closing of the issuance and sale of the Common Shares and the Option (the “Closing”) shall take place at the offices of Xxxxxx & Xxxxxx LLP in Houston, Texas on the date (such date, the “Closing Date”) determined pursuant to Section 1(a) of the Deposit Agreement, dated September 24, 2010, by and between the Company and Purchaser (the “Deposit Agreement”).

The Company has obtained and is maintaining in full force and effect all material permits, licenses and approvals required by all Environmental Laws applicable to the Premises and the business operations conducted thereon and is in compliance with all such permits, licenses and approvals, except as such non-compliance would not, individually or in the aggregate, reasonably be expected to cause a Material Adverse Change.

The term “Hazardous Substances” includes oil, gas and other hydrocarbons, asbestos, polychlorinated biphenyls, urea formaldehyde and any materials classified as hazardous or toxic under any Environmental Laws.

TERMS OF PREFERRED STOCK

1.	Economic and Voting Rights	The Preferred Stock will provide for economic and voting rights identical to the Common Stock on an as-converted basis and will vote as a single class with the Common Stock, except as otherwise provided by law. The Preferred Stock will be entitled only to such dividends as may be declared on the Common Stock and shall not have any preference in dividends or in liquidation and will rank pari passu in liquidation with the Common Stock on an as-converted basis.
2.	Director Designation Rights	Holders of a majority of the issued and outstanding shares of the Preferred Stock will provide a holder thereof with the right to designate and appoint a director to serve on the Company’s Board of Directors to serve until the Company’s next annual meeting of shareholders, and thereafter if such director may be nominated and elected by the stockholders of the Company.
3.	Conversion	Each share of Preferred Stock will convert on a one-for-one basis into a share of the Common Stock. All of the outstanding shares of Preferred Stock will automatically convert to an equivalent number of shares of Common Stock upon the earlier of (i) the exercise of the Preferred Stock holder’s right to designate and appoint a director to serve on the Company’s Board of Directors pursuant to the terms thereof and (ii) December 31, 2010.

Exhibit A-1

EXHIBIT B

REGISTRATION RIGHTS

1.	Registrable Securities	The Common Shares (and the shares of Common Stock issuable upon conversion of the Preferred Stock) will constitute “Registrable Securities” for so long as Purchaser (i) owns at least 10% of the issued and outstanding shares of the Company’s Common Stock and (ii) a director that is an officer or director of Purchaser or an Affiliate of Purchaser serves on the Board. The Common Shares will also cease to be “Registrable Securities” under customary circumstances, including when the Common Shares are sold pursuant to an effective registration statement or pursuant to Rule 144 and when the Common Shares cease to be outstanding.
2.	Demand Rights	Purchaser will be entitled to exercise two demand rights with respect to registration of the Common Shares. Subject to the priority provisions and exceptions to its obligations, the Company will be obligated to effect the registration of the Common Shares as soon as reasonably practicable upon receipt of a demand request. The Company will be entitled to defer the registration of the Common Shares pursuant to a demand request for a period of 60 days once in a 12-month period if the Board determines in good faith that filing the registration statement would be seriously detrimental to the Company or would materially and adversely affect a prospective or pending material transaction.
3.	Piggyback Rights	Subject to the priority provisions, Purchaser will be entitled to piggyback rights with respect to any registration statement the Company proposes to file, with customary exceptions including registration statements on Form S-4 and Form S-8.
4.	Lock-up Period	Purchaser will not be entitled to exercise its registration rights until the one year anniversary of the Closing under the Subscription Agreement. In addition, in the event of any underwritten public offering of Common Stock by the Company, Purchaser shall agree to execute and deliver customary lock-up agreements for the same post-offering period as may apply to executive officers and directors of the Company.

Exhibit B-1

5.	Blackout Period	As an insider, Purchaser will be subject to restrictions on sales of the Common Shares during blackout periods imposed by the Company as a result of material information or developments known to the Company and not yet known to the public.
7.	Priority	If the managing underwriter of an underwritten public offering determines that the inclusion of all registrable securities in the registration statement will materially and adversely interfere with the marketing of the offering, the Company and OCM GW Holdings, LLC (“Oaktree”) will be entitled to priority over the rights of Purchaser to include the Common Shares in such registration statement. Purchaser will acknowledge the priority rights of Oaktree in the definitive registration rights agreement that includes these provisions.
8.	Expenses	Purchaser will be responsible for costs and expenses incurred by Purchaser and the Company as a result of the exercise of its demand rights. Purchaser will be responsible for its own direct costs (e.g., registration fees and any underwriting discount) in connection with the exercise of its piggyback rights.
9.	Transferability	Purchaser will be entitled to transfer its registration rights to any of its affiliates if the transfer is in accordance with applicable securities laws and prior written notice is provided to the Company.
