No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party that is not set forth expressly in this Agreement. This Agreement contains the entire agreement, and supersedes any other agreement or understanding between Company and Employee relating to Employee’s employment, provided, however, that if and to the extent that Company has previously granted equity or other similar compensation to Employee that is subject to a vesting schedule, contingency or performance condition, this Agreement does not alter Employee’s entitlement to such compensation in accordance with the original terms thereof. With respect to the provision in Section 2.3 of Employee’s April 1, 2008, employment agreement with Company entitling Employee to an overriding royalty interest on all oil and gas properties identified and recommended by Employee during the three year term of that agreement, Employee remains entitled to such royalties but is not entitled to royalties on any other properties. Employee represents and warrants that his employment by Company hereunder does not and will not conflict with or constitute a breach or default under any prior or existing agreement with any former employer or other person or entity.
