(b) Selling Shareholders agree: (1) that Selling Shareholder will not sell, assign, pledge, give, transfer or otherwise dispose of the Shares or any interest therein, or make any offer or attempt to do any of the foregoing, except pursuant to a registration of the Shares under the Act and all applicable Securities Laws or in a transaction which is exempt from the registration provisions of the Act and all applicable Securities Laws; and (2) that Parent and any transfer agent for the Shares shall not be required to give effect to any purported transfer of any of the Shares except upon compliance with the foregoing restrictions. 9 Section 5.4.

Parent shall take all action necessary to authorize and cause Sub to consummate the Merger. The Board of Directors of each of Parent and the Company shall recommend such approval and Parent and the Company shall each take all lawful action to solicit such approval; provided, however, that such recommendation is subject to any action believed in good faith after consultation with independent counsel to be required by the fiduciary duties of the Board of Directors of the Company under applicable law and any such action shall not constitute a breach of this Agreement. Parent and the Company shall coordinate and cooperate with respect to the timing of such meetings and shall use their best efforts to hold such meetings on the same day. Section 5.5.

(the "Company") have merged the Company with Sub (the "Merger"). Sub is now the surviving entity which owns and operates the oil and gas properties ("Oil and Gas Leases") as a result of the Merger. B. In connection with the Merger, Parent and Sub have requested, and Selling Shareholder has agreed, to provide appropriate covenants of non- competition, confidentiality and non-solicitation for a certain period. NOW, THEREFORE, for valuable consideration received from Parent, including, without limitation, the monetary and other consideration paid or delivered by Parent to Selling Shareholder in connection with the Merger, Selling Shareholder and Parent hereby agree as follows: 105 TERMS OF AGREEMENT: 1. ACKNOWLEDGMENT OF CONFIDENTIAL INFORMATION AND COVENANT OF NON- DISLOSURE. (a) CONFIDENTIAL INFORMATION. Selling Shareholder acknowledges that the business which will be operated by Parent using the business assets as a result of the Merger involves valuable, confidential and/or proprietary data including names of potential lessors, drilling techniques, geologic data and technical information regarding the area in which the Oil and Gas Leases are situated and/or other information concerning the assets and business operations, products, services and/or personnel or business, acquired (the "Confidential Information") which, if used or disclosed could be utilized by potential Parent or Sub competitors. (b) COVENANT OF NON DISCLOSURE. Due to the reasonable possibility that use of disclosure of the Confidential Information will adversely affect the business of the Parent or Sub or give to a competitor a competitive advantage, then for a period commencing with the Effective Date and ending twenty-four (24) months following the Effective Date of the Merger, Selling Shareholder shall not, without the prior written consent of the Parent or Sub, use for his own benefit, or disclose to any person, any of the Confidential Information. 2. NON-COMPETITION COVENANT. For a period from the Effective Date until the twenty-four (24) month anniversary of the Effective Date, Selling Shareholder shall not compete with Parent or Sub within a 200-mile radius of the Oil and Gas Leases. The term "compete" shall mean that Selling Shareholder, shall not, directly or indirectly, participate in asset ownership, stock ownership, employment with, consultation to, financing for, or brokerage for any other person or entity which is in the business of acquiring, developing, marketing or operating oil and gas properties without written consent of Parent or Sub. Such restrictions shall not be construed to prohibit stock ownership in publicly traded companies. 106 3. COVENANT OF NON-SOLICITATION. For a period commencing with the Effective Date and ending twenty-four (24) months following the Effective Date, Selling Shareholder shall not solicit or assist any other person in soliciting any existing Oil and Gas Lease lessor or potential lessor within the restricted radius to withdraw, curtail or cancel its business dealings with Parent or Sub or commit any other act which might injure the business of Parent or Sub. For the same period, Selling Shareholder further agrees that Selling Shareholder will not solicit for employment or otherwise cause or induce any employee of Parent or Sub to voluntarily terminate his or her employment with Parent or Sub for the purpose of seeking other employment. 4. RIGHTS AND REMEDIES. If Selling Shareholder breaches or threatens to commit a breach of any of the provisions of this Agreement, Parent or Sub shall have the following rights and remedies, each of which will be in addition to, and not in lieu of, any other rights and remedies available to Parent or Sub at law or in equity: (a) Specific Performance. The right and remedy to have the terms of this Agreement specifically enforced or to have any actual or threatened breach thereof enjoined by any court having equity jurisdiction, all without the need to post a bond or any other security or to prove any amount of actual damage or that money damages would not provide an adequate remedy, it being acknowledged and agreed that any such breach or threatened breach will cause irreparable injury to Parent and Sub and that monetary damages will not provide an adequate remedy to Parent and Sub; and 107 (b) Accounting and Indemnification. The right and remedy to require Selling Shareholder (i) to account for and pay over to Parent and Sub all compensation, profits, monies, accruals, increments or other benefits derived or received by Selling Shareholder or any associated party deriving such benefits as a result of any such breach of any of the covenants made by Selling Shareholder in this Agreement; and (ii) to indemnify Parent and Sub against any other losses, damages (including special and consequential damages), costs and expenses, including actual attorneys' fees and court costs, which may be incurred by them and which result from or arise out of any such breach or threatened breach of the covenants of this Agreement. 5. ATTORNEY'S FEES. In the event of any action, suit or other proceeding concerning the negotiation, interpretation, validity, performance or breach of this Agreement, the prevailing party shall recover all of such party's actual attorneys' fees, expenses and costs, not limited to costs of suit, incurred in each and every such action, suit or other proceeding including any and all appeals or petitions relating thereto.
