Each party shall hold in confidence all nonpublic information until such time as such information is otherwise publicly available and, if this Agreement is terminated, each party will deliver to the other all documents, work papers and other materials (including copies) obtained by such party or on its behalf from the other party as a result of this Agreement or in connection herewith, whether so obtained before or after the execution hereof. Notwithstanding the foregoing, the Confidentiality Agreement dated August 1, 2007 between the

Section 6.2 Meeting of Company Stockholders; Conditions to Change of Recommendation; Superior Proposal; Notification.

(a) The Company shall take all action necessary to convene and hold a meeting of the Company’s stockholders (the “Company Stockholders’ Meeting”), which shall, in addition to the matters described herein, satisfy the requirements to act as the Company’s 2008 annual meeting of stockholders, to be held as promptly as practicable after receipt of confirmation that the SEC has no further comments to the Proxy, for the purpose of authorizing and approving: (i) the issuance of Common Shares to the holders of Membership Interests as a result of the Transactions, (ii) the adoption of an amendment to the Company’s Articles of Incorporation to increase the number of authorized Common Shares to 500,000,000, (iii) the election of each of the Director Nominees (and no other persons) to the Company’s Board of Directors, (iv) the approval of the adoption of the 2008 LTIP and the grant of the LTIP Options and (v) the adoption of an amendment to the Company’s Articles of Incorporation to change the Company’s name to “Crusader Energy Group Inc.” (collectively, the “Required Proposals”) and (vi) the approval of a 1 for 2 reverse split of the Common Shares (the “Reverse Stock Split”) (the “Other Proposal”). Unless the Board of Directors of the Company has made a Change of Recommendation pursuant to Section 6.2(c), the Company will use its reasonable best efforts to solicit from its stockholders proxies in favor of the Required Proposals and the Other Proposal and will take all other action necessary or advisable to obtain such approvals and to secure the requisite affirmative vote of its stockholders. In each case, the Company (A) shall consult with the Crusader Representative regarding the date of the Company Stockholders’ Meeting, and (B) shall not postpone or adjourn the Company Stockholders’ Meeting without the prior written consent of Crusader Representative; provided, however, that the Company may, and the Company shall upon the request of the Crusader Representative, adjourn or postpone the Company Stockholders’ Meeting to the extent necessary to ensure that any necessary supplement or amendment to the Proxy is provided to the Company’s stockholders in advance of a vote on the Required Proposals or if, as of the time for which the Company Stockholders’ Meeting is originally scheduled, there are insufficient Common Shares represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Company Stockholders’ Meeting. The Company shall call, notice, convene, hold and conduct the Company Stockholders’ Meeting, and solicit proxies in connection with the Company Stockholders’ Meeting, in compliance with the Nevada Revised Statutes, its articles of incorporation and bylaws, the rules of the American Stock Exchange and all other applicable laws and regulations. The Company’s obligation to call, give notice of, convene and hold the Company Stockholders’ Meeting in accordance with this Section 6.2(a) shall not be limited to or otherwise affected by the commencement, disclosure, announcement or submission to the Company of any Acquisition Proposal or Superior Proposal unless there has been a Change of Recommendation in which case the Company Stockholders’ Meeting shall be cancelled. At any time prior to the mailing of the definitive Proxy, the Crusader Entities may amend Exhibit A of the LTIP (provided any such amendment may not increase the total number of Common Shares that may be purchased upon exercise of the LTIP Options) and such amendments shall be reflected in the Proxy.

(b) Unless the Board of Directors of the Company has made a Change of Recommendation pursuant to Section 6.2(c): (i) the Board of Directors of the Company shall recommend that the Company’s stockholders vote in favor of and adopt and approve the Required Proposals and the Other Proposal at the Company Stockholders’ Meeting; (ii) the Proxy shall include a statement to the effect that the Board of Directors of the Company has recommended that the Company’s stockholders vote in favor of and adopt and approve the Required Proposals and the Other Proposal at the Company Stockholders’ Meeting; (iii) neither the Board of Directors of the Company nor any committee thereof shall withdraw, amend or modify, or propose or resolve to withdraw, amend or modify in a manner adverse to the Transactions, the recommendation of the Board of Directors of the Company that the Company’s stockholders vote in favor of and adopt and approve the Required Proposals and the Other Proposal; and (iv) except as otherwise permitted by Section 6.2, the Company shall not, and shall cause its Subsidiaries not to, enter into any letter of intent, agreement in principle, merger, acquisition or similar agreement with respect to any Acquisition Proposal.

(c) If all of the following conditions in clauses (i) through (viii) below are met, nothing in this Agreement shall prevent the Board of Directors of the Company, in response to the receipt of a Superior Proposal, from withholding, withdrawing, amending or modifying its recommendation in favor of the Required Proposals and the Other Proposal, and, in the case of a Superior Proposal that is a tender or exchange offer made directly to its stockholders, may recommend that its stockholders accept the tender or exchange offer (any of the foregoing actions, whether by the Board of Directors of the Company or a committee thereof, a “Change of Recommendation”):

(i) a Superior Proposal is made to the Company and is not withdrawn;

(ii) the Company Stockholders’ Meeting has not occurred; provided, however, that if the meeting is adjourned in accordance with Section 6.2(a), then such meeting shall not be deemed to have occurred for purposes of this clause (ii);

(iii) the Company shall have provided to the Crusader Representative a copy of all written materials delivered after the date of this Agreement to the Person or group making the Superior Proposal in connection with such Superior Proposal, and shall make available to the Crusader Representative all written materials and information made available to the Person or group making the Superior Proposal in connection with such Superior Proposal;

(iv) the Company shall provide the Crusader Representative with at least two business days prior notice (or such lesser prior notice as provided to the members of the Company’s Board of Directors) of any meeting of the Company’s Board of Directors at which the Company’s Board of Directors is reasonably expected to consider any Acquisition Proposal to determine whether such Acquisition Proposal is a Superior Proposal;

(v) the Company shall have provided written notice to the Crusader Representative (a “Notice of Superior Proposal”) advising the Crusader Entities that the Company has received a Superior Proposal and that the Board intends to effect a Change

of Recommendation and the manner in which it intends to do so, specifying in reasonable detail all of the material terms and conditions of such Superior Proposal and identifying the Person, entity or group making such Superior Proposal;

(vi) the Crusader Entities shall not have, within five business days after the Crusader Representative’s receipt of the Notice of Superior Proposal (it being understood and agreed that the receipt of a Modified Superior Proposal during such five business day period shall require a new Notice of a Superior Proposal and a new five day period with respect to such Modified Superior Proposal), made a Matching Bid (as hereinafter defined) that the Company’s Board of Directors by a majority vote determines in its good faith judgment (after consultation with and the receipt of advice from its outside legal counsel and its financial advisor) to be at least as favorable to the Company’s stockholders as such Superior Proposal (it being agreed that the Board of Directors of the Company shall convene a meeting to consider any such Matching Bid by the Crusader Entities reasonably promptly following the receipt thereof and that the Board of Directors of the Company will not withhold, withdraw, amend or modify its recommendation to the Company’s stockholders in favor of approval and adoption of the Required Proposals or the Other Proposal for five business days after receipt by the Crusader Entities of the Notice of Superior Proposal);

(vii) the Board of Directors of the Company concludes in good faith, after consultation with and receipt of advice from its outside legal counsel, that, in light of such Superior Proposal and any Matching Bid, the failure to effect a Change of Recommendation would be a breach of its fiduciary obligations to the Company’s stockholders under applicable Legal Requirements; and

(viii) The Company shall have complied in all material respects with this Section 6.2 and Sections 6.1 and 6.3.

(d) Nothing contained in this Agreement shall limit the Company’s obligation to call, give notice of, hold and convene the Company Stockholders’ Meeting (regardless of the commencement, disclosure, announcement or submission to the Board of Directors of the Company of any Acquisition Proposal) unless there has been a Change of Recommendation, in which case the Company Stockholders’ Meeting shall be cancelled. The Company shall not submit to the vote of its stockholders for a vote any Acquisition Proposal or propose or agree to do so at or prior to the Company Stockholders’ Meeting.

(e) For purposes of this Agreement, “Superior Proposal” shall mean any unsolicited Acquisition Proposal (with all of the percentages included in the definition of Acquisition Proposal changed to fifty percent (50%) for purposes of this definition), on terms that the Board of Directors of the Company concludes in good faith, after consultation with and receipt of advice from its outside financial advisors and outside legal counsel, taking into account, among other things, all legal, financial, regulatory and other aspects of the offer, the Person or group making the offer and the source of financing, to be (i) more favorable to the Company’s stockholders from a financial point of view than the terms of the Transactions, taking into account all the terms and conditions of such proposal and this Agreement (including any proposal by either party to amend the terms of this Agreement) and the Person making the offer,

and (ii) reasonably capable of being consummated without undue delay on the terms as proposed; provided, however, that any such offer shall not be deemed to be a Superior Proposal if any financing required to consummate the transaction contemplated by such offer is not committed or if there is a general due diligence condition to any party’s obligations to consummate the transaction that is the subject of the Superior Proposal.

(f) Nothing contained in this Agreement shall prohibit the Company or its Board of Directors from taking and disclosing to its stockholders a position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act; provided, however, that the Company shall not effect a Change of Recommendation unless specifically permitted pursuant to Section 6.2(c).

(g) Notwithstanding anything in this Section 6.2 to the contrary, at any time prior to satisfaction of the conditions in Section 7.2(f), concurrently with or after a Change of Recommendation, the Board of Directors of the Company may, in response to a Superior Proposal that did not result from a breach of this Agreement, cause the Company to terminate this Agreement pursuant to Section 9.1(h) and concurrently with such termination enter into a definitive agreement providing for the transactions contemplated by such Superior Proposal; provided, however, that the Company shall not terminate this Agreement pursuant to Section 9.1(h), and any purported termination pursuant to Section 9.1(h) shall be void and of no force or effect, unless the Company shall have complied in all material respects with all the provisions of this Section 6.2 and Sections 6.1 and 6.3, including the notification provisions in this Section 6.2(g), and with all applicable requirements of Section 9.2(b) (including the payment of the Termination Fee prior to or concurrently with such termination) in connection with such Superior Proposal; and provided further, however, that the Company shall not exercise its right to terminate this Agreement pursuant to Section 9.1(h): (i) until after the fifth business day after the date of delivery of a Notice of Superior Proposal and stating that the Board of Directors of the Company intends to cause the Company to exercise its right to terminate this Agreement pursuant to Section 9.1(h) (it being understood and agreed that, prior to any termination pursuant to Section 9.1(h) taking effect, any amendment to the price or any other material term of a Superior Proposal (such amended Superior Proposal, a “Modified Superior Proposal”) shall require a new Notice of Superior Proposal and a new five business day period with respect to such Modified Superior Proposal) and (ii) unless either (x) on or before the expiration of the five business day period after the date of the delivery to the Crusader Representative of any Notice of Superior Proposal, the Crusader Entities do not make a good faith written proposal (a “Matching Bid”) in response to such Superior Proposal or (y) following receipt of a Matching Bid, the Board of Directors of the Company concludes in good faith, after consultation with and the receipt of advice from its outside legal counsel and financial advisors and after taking into consideration the Matching Bid, that the Superior Proposal to which the Notice of Superior Proposal relates continues to be a Superior Proposal.

(h) For purposes of this Agreement, “Acquisition Proposal” shall mean any offer or proposal (other than an offer or proposal by the Crusader Entities) relating to, or involving: (A) any acquisition or purchase from the Company by any Person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) of more than a 15% interest in the total outstanding voting securities of the Company or any of its Subsidiaries or any tender offer or exchange offer that if consummated would result in any

Person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) beneficially owning 15% or more of the total outstanding voting securities of the Company or any of its Subsidiaries or any merger, consolidation, business combination or similar transaction involving the Company pursuant to which the stockholders of the Company immediately preceding such transaction hold less than 85% of the equity interests in the surviving or resulting entity of such transaction; (B) any sale, lease (other than in the ordinary course of business), exchange, transfer, license (other than in the ordinary course of business), acquisition, or disposition of more than 15% of the assets of the Company and its Subsidiaries, taken as a whole; or (C) any liquidation, dissolution, recapitalization or other significant corporate reorganization of the Company.

(i) As used in this Agreement, the term “Superior Proposal” shall be deemed to mean a “Modified Superior Proposal” if a Modified Superior Proposal has been made.

(j) Nothing contained in this Section 6.2 shall permit the Company or any of its Subsidiaries to enter into any letter of intent, memorandum of understanding, term sheet or agreement contemplating or otherwise relating to an Acquisition Proposal other than a confidentiality agreement containing terms no less favorable to the Company than the Confidentiality Agreement until the termination of this Agreement pursuant to Article IX.

Section 6.3 No Solicitation.

(a) From and after the date of this Agreement until the Closing or termination of this Agreement pursuant to Article IX, the Company shall not, nor shall it authorize or permit its Subsidiaries or any of its or their respective officers, directors, affiliates, Company Employees or consultants or any investment banker, attorney, advisor or other agent or representative retained by any of them to, directly or indirectly, (i) solicit, initiate, seek, entertain, encourage, facilitate, support or induce the making, submission or announcement of any Acquisition Proposal, (ii) continue or participate in any discussions or negotiations regarding, or furnish to any Person any information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes, or may reasonably be expected to lead to, any Acquisition Proposal, (iii) grant any waiver or release under any standstill or similar agreement with respect to any class or series of the capital stock of the Company, (iv) engage or participate in discussions with any Person with respect to any unsolicited Acquisition Proposal, except as necessary to ascertain the terms of and understand any Acquisition Proposal and to decline to engage or participate in such discussions by referring to the existence of these provisions, (v) approve, endorse or recommend any Acquisition Proposal, except as specifically provided in Section 6.2(b), or (vi) enter into any letter of intent, memorandum of understanding, term sheet or agreement contemplating or otherwise relating to any Acquisition Proposal; provided, however, that this Section 6.3 shall not prohibit the Company, prior to satisfaction of the conditions in Section 7.3(f), from engaging in discussions or negotiations regarding or furnishing information to the party making an unsolicited, written, bona fide Acquisition Proposal so long as, and only to the extent that, (A) the Company’s Board of Directors in good faith, after consultation with and receipt of advice from its outside financial and outside legal advisors, concludes that such Acquisition Proposal is, or would reasonably be expected to result in, a Superior Proposal, (B) neither the Company nor any representative of the Company or its Subsidiaries acting under its authority shall have violated any of the restrictions set forth in

Section 6.1 or Section 6.2 or this Section 6.3, (C) the Board of Directors of the Company concludes in good faith, after consultation with and receipt of advice from its outside financial and outside legal counsel, that such action is required in order for the Board of Directors of the Company to comply with its fiduciary obligations to the Company’s stockholders under applicable Legal Requirements, (D) at least two business days prior to entering into discussions or negotiations (other than preliminary discussions permitted above) with, or furnishing information to, such party, the Company gives the Crusader Entities written notice of the identity of such Person, entity or group and all of the material terms and conditions of such Acquisition Proposal and of the Company’s intention to take action with respect to such Person, entity or group, and the Company receives from such Person or group an executed confidentiality agreement containing terms no less favorable to the Company than the Confidentiality Agreement, (E) the Company gives the Crusader Entities at least two business days advance notice of its intent to furnish such nonpublic information or enter into such discussions, and (F) contemporaneously with furnishing any such information to such Person or group, the Company furnishes such information to the Crusader Entities (to the extent such information has not been previously furnished by the Company to the Crusader Entities).

(b) The Company shall, as promptly as practicable, and in any event within 24 hours after the receipt thereof, advise the Crusader Entities orally and in writing of any Acquisition Proposal, request for information which the Company reasonably believes would lead to an Acquisition Proposal or any inquiry with respect to or which could reasonably be expected to lead to any Acquisition Proposal, the material terms and conditions of such Acquisition Proposal, request or inquiry, any material modification or material amendment to the terms and conditions of such Acquisition Proposal, the identity of the Person or group making any such Acquisition Proposal, request or inquiry and copies of all written materials sent or provided to the Company by or on behalf of any Person or group or provided to such Person or group by or on behalf of the Company after the date of this Agreement. The Company shall take reasonable efforts to keep the Crusader Entities informed in all material respects of the status and details (including material amendments or proposed amendments) of any such Acquisition Proposal, request or inquiry.

(c) The Company shall immediately cease, and shall cause any Person acting on its behalf to cease, and cause to be terminated any existing discussions or negotiations with any third party conducted heretofore with respect to any Acquisition Proposal and shall request any such third parties in possession of confidential information about the Company or any of its Subsidiaries that was furnished by or on behalf of the Company or any such Subsidiary to return or destroy all such information in the possession of such third party or the agent or advisor of such third party.

Section 6.4 Directors’ and Officers’ Indemnification and Insurance.

(a) For six years after the Closing, the Company shall indemnify, defend and hold harmless each person who is now, or has been at any time prior to the date hereof or who becomes prior to the Closing, an officer or director of the Company or any Subsidiary of the Company (each an “Indemnified Party”), who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, or investigative (a “proceeding”), against all losses, damages, liabilities, fees and expenses

(including reasonable fees and disbursements of counsel and experts and judgments, fines, losses, claims, liabilities and amounts paid in settlement (provided that any such settlement is effected with the prior written consent of the Company, which will not be unreasonably withheld)) actually and reasonably incurred by the Indemnified Party because the Indemnified Party is or was a director or officer of the Company or any Subsidiary of the Company pertaining to any act or omission existing or occurring at or prior to the Closing including any act or omission relating to this Agreement or the Transactions (the “Indemnified Liabilities”) to the full extent permitted under Nevada law or the Company’s articles of incorporation and bylaws. If an Indemnified Party makes or asserts any claim for Indemnified Liabilities, any determination required to be made with respect to whether an Indemnified Party’s conduct complies with the standards set forth under the Nevada Revised Business Corporations Act shall be made by independent counsel mutually acceptable to the Company and the Indemnified Party; and provided, further, that nothing herein shall impair any rights or obligations of any Indemnified Party. If any claim or claims are brought against any Indemnified Party (whether arising before or after the Closing), such Indemnified Party may select counsel for the defense of such claim, which counsel shall be reasonably acceptable to the Company.

(b) The Company shall promptly advance all reasonable out-of-pocket expenses of each Indemnified Party in connection with any such action or proceeding described above, as such expenses are incurred, to the fullest extent permitted by the Nevada Revised Business Corporations Act, subject to the receipt by the Company of an undertaking by or on behalf of such Indemnified Party to repay such amount if it shall ultimately be determined that such Indemnified Party is not entitled to be indemnified by the Company.

(c) The Company shall maintain the Company’s existing officers’ and directors’ liability insurance policy (“D&O Insurance”) for a period of at least six years after the Closing, but only to the extent related to actions or omissions prior to the Closing; provided, that the Company may substitute therefor (i) policies of substantially similar coverage and amounts containing terms no less advantageous to such former directors or officers or (ii) a run-off directors’ and officers’ liability insurance policy for the Company’s current policies to be effective from and after the Closing with respect to claims arising from facts or events which occurred prior to the Closing and covering persons who are currently covered by such insurance, which policy, without any lapse in coverage, will provide coverage for a period of six years after the Closing (or the Company otherwise will maintain coverage for such period) and contain terms and conditions which are substantially comparable to the Company’s existing directors’ and officers’ liability insurance policy.

Section 6.5 Further Assurances. Each party shall use commercially reasonable efforts to obtain all consents and approvals and to do all other things necessary for the consummation of the Transactions; provided, however, that in no event shall any party or its Subsidiaries be required to pay, and without the Crusader Representative’s prior consent the Company and its Subsidiaries shall not pay, any fee, penalties or other consideration to any third party under any agreement to obtain any consent or approval required for the consummation of the Transactions. The parties shall take such further action to deliver or cause to be delivered to each other at the Closing and at such other times thereafter as shall be reasonably agreed by such parties such additional agreements or instruments as any of them may reasonably request for the purpose of carrying out this Agreement and the Transactions. The parties shall afford each other

access to all information, documents, records and personnel who may be necessary for any party to comply with laws or regulations (including the filing and payment of taxes and handling tax audits), to fulfill its obligations with respect to indemnification hereunder or to defend itself against suits or claims of others. The Company and the Crusader Operating Entities shall duly preserve all files, records or any similar items of the Company or the Crusader Operating Entities received or obtained as a result of the Transactions with the same care and for the same period of time as it would preserve its own similar assets.

Section 6.6 Expenses.

(a) Except as provided in Section 9.2(c) and Section 6.16, the Crusader Operating Entities shall bear and timely pay all Expenses incurred by the Crusader Entities (pro rata in relation to the number of Common Shares to be delivered pursuant to Sections 1.1(a), (b), (d) and (e) to the Crusader Parent Entity owning the membership interest of such Crusader Operating Entity) and the Company shall bear and timely pay all Expenses incurred by the Company and its Subsidiaries; provided, however, that if this Agreement is terminated for any reason, then, except as provided in Section 9.2(c) and Section 6.16, the allocable share of the Company and the Crusader Operating Entities for all Expenses (including any fees and expenses of accountants, experts, and consultants, but excluding the fees and expenses of outside legal counsel and investment bankers) related to preparing, printing, filing and mailing the Proxy and all SEC and other regulatory filing fees incurred in connection with the Proxy and, if required, the HSR Act shall be allocated one-half each (and, as among such one-half allocated to the Crusader Operating Entities, pro rata as provided above); provided, further, however, that (i) if the Crusader Entities terminate this Agreement pursuant to the Company’s breach pursuant to Section 9.1(c), then the Crusader Entities shall not be required to pay any of the Company’s Expenses or (ii) If the Company terminates this Agreement pursuant to a breach by a Crusader Entity pursuant to Section 9.1(d), then the Company shall not be required to pay any of the Crusader Entities’ Expenses.

(b) “Expenses” as used in this Agreement shall include all reasonable out-of-pocket expenses (including all reasonable fees and expenses of outside legal counsel, accountants, auditors, financing sources, investment bankers, experts and consultants to a party hereto and its affiliates) incurred by a party or on its behalf in connection with or related to the due diligence, authorization, preparation, negotiation, execution and performance of this Agreement and the Ancillary Agreements, the preparation, printing, filing and mailing of the Proxy, the solicitation of stockholder approval, HSR Act filings, if required, and all other matters related to the consummation of the Transactions (subject to reasonable documentation).

Section 6.8 Publicity. Neither the Company, the Crusader Entities, nor any of their respective affiliates shall issue or cause the publication of any press release or other

announcement or public statement (including any statements to stockholders of the Company) with respect to the Transactions without the prior consultation of the other parties, and shall not issue any such press release or make any such announcement or public statement (including any statements to stockholders of the Company) without the consent of the other parties, except as may be reasonably determined to be required by applicable law or by any listing agreement with a national securities exchange, and each party shall use reasonable efforts to provide copies of such release or other announcement to the other party hereto, and give due consideration to such comments as each such other party may have, prior to such release or other announcement. Without limiting the foregoing, neither the Company, the Crusader Entities, nor any of their respective affiliates shall issue or cause the publication of any presentation to be provided orally or in writing to third parties, including any presentation to be made to stockholders of the Company or the owners of the Crusader Entities, regarding the Transactions, without consulting with the other party regarding the Persons to whom such presentations shall be provided, the timing of delivery of such presentations and the representatives of the Company and the Crusader Entities who shall be present at each delivery of such presentation (it being agreed that each of the Company and the Crusader Entities shall be entitled to have at least one representative present at each delivery of such presentation), and shall not make any such presentation without the consent of the other parties, except as may be reasonably determined to be required by applicable law or by any listing agreement with a national securities exchange.

Section 6.9 Additional Actions. Subject to the terms and conditions of this Agreement, each party agrees to use commercially reasonable efforts to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations, or to remove any injunctions or other impediments or delays, to consummate and make effective the Transactions, subject, however, to the Company Stockholders’ Approval.

Section 6.12 Company Board of Directors.

(a) As of the date of this Agreement, certain of the existing directors of the Company shall have executed and delivered to the Company an irrevocable resignation, in the form of Exhibit E hereto (a “Resignation”), of their position as a director effective as of the Closing and the parties hereto contemplate that additional Resignations will be delivered as contemplated by Section 6.26. From time to time following the date hereof, the Crusader Representative may deliver to the Company (i) a writing identifying one or more persons to be

included in the Proxy (the “Director Nominees”) for election, effective as of the Closing, as members of the Company’s Board of Directors, (ii) biographical descriptions of each Director Nominee, with each such description containing all of the information required to be disclosed about nominees for directors in a proxy statement filed with the SEC, (iii) a completed directors questionnaire executed by the Director Nominee in a form reasonably acceptable to the Company, and (iv) a written statement executed by the Director Nominee consenting to serve as a director of the Company if so elected. Each such Director Nominee shall be acceptable to the Company’s Board of Directors, acting reasonably. If the Company does not notify the Crusader Representative whether the Director Nominee is acceptable to the Company’s Board within five business days following receipt of such notice, the Company shall be deemed to have delivered notice that such Director Nominee is not acceptable to the Company’s Board of Directors.

(b) If, at any time prior to Closing, any Director Nominee who was deemed acceptable by the Company’s Board of Directors is unable, for any reason, to serve as a director, the Crusader Representative may propose to the Company’s Board of Directors a replacement director by providing the information regarding such proposed replacement specified in paragraph (a) of this Section. Each such replacement Director Nominee shall be acceptable to the Company’s Board of Directors, acting reasonably. If the Company does not notify the Crusader Representative whether the proposed replacement Director Nominee is acceptable to the Company’s Board within five business days following receipt of such notice, the Company shall be deemed to have delivered notice that such proposed replacement Director Nominee is not acceptable to the Company’s Board of Directors.

(c) The composition of the committees of the Company’s Board of Directors immediately following the Closing (including the respective chairmen thereof) shall be as designated at or immediately following the Closing in the sole discretion of the Company’s Board of Directors but shall meet the independence and other standards of the AMEX and the SEC.

Section 6.13 Preparation of the Proxy. The Company shall prepare and, as soon as possible following delivery of the 2006 Audit Opinions, file with the SEC a preliminary version of the Proxy and will use commercially reasonable efforts to respond to the comments of the SEC in connection therewith and to furnish all information required to prepare the definitive Proxy. The Company shall take any action (other than qualifying to do business in any jurisdiction in which it is not now so qualified or filing a general consent to service of process in any jurisdiction) required to be taken under any applicable state securities laws in connection with the issuance of Common Shares in the Transactions and the Crusader Operating Entities shall furnish all information concerning the Crusader Operating Entities and the holders of Membership Interests and Stock Interests as may be reasonably requested in connection with any such action and which meets the requirements of any applicable rules and regulations promulgated by the SEC. The Company shall as promptly as practicable notify the Crusader Representative of the receipt of any oral or written comments from the SEC relating to the Proxy. The Company shall cooperate and provide the Crusader Representative with a reasonable opportunity to review and comment on the draft of the Proxy (including each amendment or supplement thereto), and all responses to requests for additional information by and replies to comments of the SEC, prior to filing such with or sending such to the SEC, and the Crusader Representative and the Company will provide each other with copies of all such filings made and

correspondence with the SEC. Promptly after the staff of the SEC advises the Company that the staff of the SEC has no further comments on the Proxy, the Company shall cause the Proxy to be mailed to its stockholders, and if necessary, after the definitive Proxy has been mailed, promptly circulate amended, supplemented or supplemental proxy materials and, if required in connection therewith, re-solicit proxies or written consents, as applicable. If at any time prior to the Closing, the officers, directors or managers of the Company or the Crusader Operating Entities discover any statement which, in light of the circumstances to which it is made, is false or misleading with respect to a material fact or omits to state a material fact necessary to make the statement made in the proxy/prospectus not misleading, then such party shall immediately notify the other party of such misstatements or omissions.

Section 6.14 Stock Exchange Listing. The Company shall use its best efforts to cause the Common Shares to be issued in the Transactions and the Common Shares subject to issuance under the 2008 LTIP to be approved and admitted for listing on the American Stock Exchange at least ten consecutive trading days prior to the Closing, subject to official notice of issuance.

Section 6.15 Notice of Certain Events. Each party to this Agreement shall promptly as reasonably practicable notify the other parties of:

(a) any notice or other communication from any Person alleging that the consent of such Person (or other Person) is or may be required in connection with the Transactions;

(b) any notice or other communication from any Governmental Authority in connection with the Transactions;

(c) any actions, suits, claims, investigations or proceedings commenced or, to the best of its knowledge, threatened against, relating to or involving or otherwise affecting it or any of its Subsidiaries which, if pending on the date hereof, would have been required to have been disclosed pursuant to Section 3.9, Section 3.11, Section 4.10 or Section 4.12, or which relate to the consummation of the Transactions;

(d) any notice of, or other communication relating to, a default or event that, with notice or lapse of time or both, would become a default, received by it or any of its Subsidiaries subsequent to the date hereof, under any material agreement; and

(e) any Crusader Entity Material Adverse Effect or Company Material Adverse Effect or the occurrence of any event which would result in a Crusader Entity Material Adverse Effect or a Company Material Adverse Effect, as the case may be.

(b) No Change of Recommendation nor any termination of this Agreement shall have any effect on any of the approvals or other actions referred to herein for the purpose of causing the Anti-Takeover Laws to be inapplicable to this Agreement and the Transactions.

(c) Neither the Board of Directors nor the stockholders of the Company shall take any action to exempt or make not subject to the provisions of any Anti-Takeover Laws, including the Acquisition of Controlling Interest Statutes or the Combinations with Interested Stockholders Statutes, any Person (other than the Crusader Entities) or any action taken thereby, which Person or action would have otherwise been subject to the restrictive provisions of such Anti-Takeover Laws and not exempt therefrom.

Section 10.2 Crusader Representative.

(a) Crusader Management is hereby appointed by each Crusader Entity (and their successors and assigns) as its representative (the “Crusader Representative”), to act as agent and attorney-in-fact for each Crusader Entity, for and on behalf of the Crusader Entities: (i) to give and receive notices and communications on their behalf with respect to any matters related to this Agreement; (ii) to litigate, mediate, arbitrate, defend or settle, or take any other actions and execute and any other documents that the Crusader Representative deems advisable in connection with enforcing any rights or obligations or defending, any claim or action under this Agreement on behalf of the Crusader Entities; (iii) to sign receipts, consents or other documents in connection with the Crusader Representative’s duties hereunder; (iv) to terminate this Agreement on behalf of each of the Crusader Entities pursuant to Section 9.1 and (v) to take

any and all actions necessary or appropriate in the judgment of the Crusader Representative for the accomplishment of the foregoing, in each case, without having to seek or obtain the consent of any Crusader Entity. Notice or communications to or from the Crusader Representative shall constitute notice to or from the Crusader Entities. All actions to be taken by a Crusader Entity shall be taken solely by the Crusader Representative.

(b) Without limiting the generality of the foregoing, the Crusader Representative shall not incur any liability with respect to any action taken or suffered by it in reliance upon any direction, instruction, consent, statement or other document believed by it to be genuinely and duly authorized, nor for any action or inaction in reliance in good faith upon advice of legal counsel. If the Crusader Representative shall dissolve, resign or otherwise be unable to fulfill its responsibilities hereunder, the Crusader Parent Entities, acting by consent of Crusader Parent Entities having an interest in the Share Consideration equal to a majority of the Common Shares constituting the Share Consideration (a “Majority”) shall, as soon as practicable after such dissolution or resignation, appoint a successor to the Crusader Representative and immediately thereafter notify the Company of the identity of such successor. If a Majority chooses to remove the Crusader Representative for any reason, such Majority shall simultaneously appoint a successor to the Crusader Representative and immediately thereafter notify the Company of the identity of such successor. Any such successor pursuant to either of the preceding two sentences shall succeed the Crusader Representative as Crusader Representative hereunder.

(c) A decision, act, consent or instruction of the Crusader Representative shall constitute a decision of the Crusader Entities and shall be final, binding and conclusive upon the Crusader Entities. The Company may rely upon any decision, act, consent or instruction of the Crusader Representative as being the decision, act, consent or instruction of the Crusader Entities. Although the Crusader Representative shall not be obligated to obtain instructions from the Crusader Entities, prior to any decision, act, consent or instruction, if, and to the extent that, the Crusader Representative receives any written instructions from a Majority, the Crusader Representative shall comply with such instructions.

(d) The Crusader Representative shall not be liable to the Crusader Entities for any act taken or omitted to be taken as Crusader Representative, except for the commission of actual fraud or willful misconduct. Each Crusader Entity shall severally indemnify the Crusader Representative and hold the Crusader Representative harmless against any damages or expenses incurred without bad faith on the part of the Crusader Representative and arising out of or in connection with the acceptance or administration of the Crusader Representative’s duties hereunder, including the reasonable fees and expenses of any legal counsel retained by the Crusader Representative.

Section 10.16 Specific Performance. The parties recognize and agree that if for any reason any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached, immediate and irreparable harm or injury would be caused for which money damages would not be an adequate remedy. Accordingly, each party agrees that, prior to any termination of this Agreement pursuant to Section 9.1, but subject to the last sentence of this Section 10.16, the parties shall be entitled to specific performance of the terms hereof.

Notwithstanding the foregoing, no Crusader Entity shall be entitled to an injunction to prevent breaches of this Agreement by the Company or to enforce specifically the terms and provisions of this Agreement if any Crusader Entity is, or collectively are, in material breach of its or their respective representations, warranties, covenants and obligations under this Agreement so as to cause any of the conditions set forth in Section 7.1 or Section 7.2 not to be satisfied.

Section 10.18 Authorship; Representation by Counsel. The parties agree that the terms and language of this Agreement were the result of negotiations between the parties and, as a result, there shall be no presumption that any ambiguities in this Agreement shall be resolved against any party. Any controversy over construction of this Agreement shall be decided without regard to events of authorship or negotiation. Each of the parties hereto acknowledges that it has

been represented by independent counsel of its choice throughout all negotiations that have preceded the execution of this Agreement.

Section 10.19 Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING, OR COUNTERCLAIM (WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.
