BUSINESS OPPORTUNITY AGREEMENT

EXHIBIT 10.13

BUSINESS OPPORTUNITY AGREEMENT

     THIS BUSINESS OPPORTUNITY AGREEMENT (this “Agreement”), dated as of June 26, 2008 is entered into by and among CRUSADER ENERGY GROUP INC., a Nevada Corporation (the “Company”), and the parties to this Agreement listed on Exhibit A hereto (each a “Designated Party” and collectively the “Designated Parties").

RECITALS

     A. Each of the Designated Parties engages, directly or indirectly, in the E&P Business.

     B. In recognition that certain Designated Parties and their respective Affiliates (other than the Company and its Subsidiaries) may engage, directly or indirectly, in the same or similar activities or lines of business and have an interest in the same or similar areas of business as the Company and its Subsidiaries, and in recognition of the benefits to be derived by the Company and its Subsidiaries through their continued contractual, corporate and business relations with each Designated Party (including services of employees, officers and directors of each Designated Party as directors and officers of the Company), this Agreement is set forth to regulate and define the conduct of certain affairs of the Company and its Subsidiaries as they may involve each Designated Party, and, as applicable, its employees, officers and directors, and the powers, rights, duties, liabilities and expectations of the Company and its Subsidiaries in connection therewith.

     C. The law relating to fiduciary and other duties that certain Designated Parties may owe to the Company is not clear. The application of such law to particular circumstances is often difficult to predict, and, if a court were to hold that any Designated Party breached any such duty, such Designated Party could be subject to claims for damages or other remedies in a legal action brought by or on behalf of the Company.

     D. In order to induce the Designated Parties to serve as directors of the Company, the Company is willing to enter into this Agreement, consistent with Section 78.070 of the Nevada Revised Statutes and other applicable provisions of law of the State of Nevada, in order to renounce, effective upon the date hereof, any interest or expectancy it may have in the classes or categories of business opportunities specified herein that are presented to or identified by any Designated Party, as more fully described herein. As a result of this Agreement, each Designated Party, as applicable, may continue to conduct her, his or its business and to pursue certain business opportunities as described herein without an obligation to offer such opportunities to the Company or any of its Subsidiaries, and any Designated Party, as applicable, may continue to discharge his, her or its responsibilities as a director or employee of such Designated Party or any company in which such Designated Party has an interest.

     NOW, THEREFORE, in consideration of the foregoing, the mutual covenants, rights and obligations set forth in this Agreement and the benefits to be derived herefrom and other good

and valuable consideration, the receipt and sufficiency of which each of the undersigned acknowledges and confesses, the undersigned agree as follows:

     1. Renouncement of Business Opportunities. The Company, for itself and each Subsidiary of the Company, hereby renounces any interest or expectancy in any Renounced Business Opportunity and waives any claim that such potential Renounced Business Opportunity should have been presented to the Company or any Subsidiary of the Company. No Designated Party shall have any obligation to communicate or offer any Renounced Business Opportunity to the Company or any Subsidiary of the Company, and any Designated Party may develop, pursue, conduct or consummate a Renounced Business Opportunity for the benefit of such Designated Party or any Third Person, provided that such Renounced Business Opportunity is developed, pursued, conducted and/or consummated, as applicable, by such Designated Party in accordance with the standard set forth in Section 2. Neither the Company nor any Subsidiary of the Company shall be prohibited from pursuing any Business Opportunity with respect to which it has renounced any interest or expectancy as a result of this Section 1.

     2. Standards for Separate Conduct of Renounced Business Opportunities. A Designated Party may pursue a Renounced Business Opportunity for the benefit of such Designated Party or any Third Person if such Renounced Business Opportunity is developed, pursued, conducted and/or consummated, as applicable, solely through the use of personnel and assets of the Designated Party (including, as applicable, such Designated Party in his capacity as a director, officer, employee or agent of the Designated Party) or any other Third Person.

     3. Liability. Provided a Renounced Business Opportunity is developed, pursued, conducted and/or consummated, as applicable, by a Designated Party in accordance with the standards set forth in Section 2 hereof, no Designated Party shall be liable to the Company, any Subsidiary of the Company or any Stockholder for breach of any fiduciary or other duty by reason of such Renounced Business Opportunity. In addition, no Designated Party shall be liable to the Company, any Subsidiary of the Company or any Stockholder for breach of any fiduciary duty as a director or controlling Stockholder, as applicable, by reason of the fact that such Designated Party develops, pursues, conducts or consummates such Renounced Business Opportunity for itself, directs such Renounced Business Opportunity to any Third Person or does not communicate information regarding such Renounced Business Opportunity to the Company or any Subsidiary of the Company.

     4. Disclosing Conflicts of Interest. Should any director of the Company have actual knowledge that he or she or his or her Affiliates (other than the Company or any Subsidiary of the Company) is pursuing a Renounced Business Opportunity also pursued by the Company (or any Subsidiary of the Company), he or she shall disclose to the Company’s board of directors that he or she may have a conflict of interest, so that the board of directors may consider requesting his or her withdrawal from discussions in board deliberations, or abstention from voting on a particular matter before the board, as appropriate.
