Employment Agreements

On June 1, 2012, the Company entered into employment agreements (the “Employment Agreements”) with the following officers of the Company (collectively, the “Officers”):

The Employment Agreements were executed based upon a form employment agreement approved by the Compensation Committee of the Board (the “Compensation Committee”) after consulting with Longnecker & Associates, an independent compensation consultant.

The Employment Agreements are for an initial term ending December 31, 2013 and automatically extend for an additional one year period every year thereafter unless either party gives written notice that the automatic extension will not occur. However, the Employment Agreement entered into with Mr. Wilson provides for an initial term of two years and may be renewed for an additional two-year period upon the express written notice of the Company.

Under the terms of the Employment Agreements, each Officer will receive an annual base salary in the amount set forth below, subject to any increase the Compensation Committee may deem appropriate from time to time.

In addition, the Officers will be eligible to receive one or more annual cash bonuses and grants of stock options, restricted stock or other equity-related awards from the Company’s various equity compensation plans, as determined by the Compensation Committee.

If the Company terminates an Officer due to the Officer’s death or inability to perform, the Employment Agreements provide for payment to the Officer of any unpaid portion of the Officer’s base salary and benefits accrued through the date of death or inability to perform and, at the discretion of the Compensation Committee, a bonus.

If the Company terminates an Officer’s Employment Agreement for “cause” or if an Officer terminates his or her Employment Agreement without “good reason” (as such terms are defined in the Employment Agreement), the Officer will not be entitled to a severance payment or any other termination benefits. However, the Company will pay the Officer any unpaid portion of the Officer’s base salary and benefits accrued through the date of such termination.

Upon a termination of an Officer’s Employment Agreement by the Company without cause or by the Officer for good reason, the Officer will be entitled to (i) any unpaid portion of the Officer’s base salary and benefits accrued through the date of termination, and (ii) the pro rated amount of the Officer’s target bonus for the year in which the date of termination occurs or such greater amount as determined by the Compensation Committee. In addition, all stock options and other incentive awards held by the Officer will become fully vested and immediately exercisable and all restrictions on any restricted stock held by the Officer will be removed.

The Officer will also be entitled to a lump sum severance payment equal to the sum of the following: (i) an amount equal to the Officer’s base salary in effect as of the date of termination, plus (ii) an amount equal to the greater of (A) the bonus payable to the Officer for the year in which the date of termination occurs or (B) the bonus paid to the Officer for the year immediately preceding the year in which the date of termination occurs. The Officer will also be entitled to receive a reimbursement of up to 12 months of Consolidated Omnibus Reconciliation Act, or COBRA, premiums, if the Officer timely elects and remains eligible for COBRA.

However, if such termination occurs within a two year period following a “change in control” (as such term is defined in the Employment Agreement), then the officer will be entitled to a severance payment calculated as a multiple (the “Severance Multiplier”) of the respective Officer’s base salary and bonus. The Severance Multiplier for each Officer is set forth below:

The Officer’s severance payment will be the Severance Multiplier multiplied by the sum of (i) an amount equal to the greater of (A) the Officer’s base salary in effect as of the date of termination or (B) the Officer’s base salary in effect immediately prior to the change in control, plus (ii) an amount equal to the greater of (A) the bonus payable to the Officer for the year in which the date of termination occurs, (B) the bonus paid to the Officer for the year immediately preceding the year in which the date of termination occurs, or (C) the bonus paid to the Officer for the year immediately preceding the year in which the change in control occurs. The Officer will also be entitled to receive a reimbursement of up to 18 months of COBRA premiums if the Officer timely elects and remains eligible for COBRA.

The Employment Agreements also contain customary confidentiality, non-competition and non-solicitation provisions. Under the non-compete provisions, during the term of his or her Employment Agreement, the Officer is prohibited from, directly or indirectly, engaging in or becoming interested financially in, as a principal, employee, partner, contractor, shareholder, agent, manager, owner, advisor, lender, guarantor, officer or director, any business that is engaged in leasing, acquiring, exploring, producing, gathering or marketing hydrocarbons and/or related products, subject to certain exceptions for passive investments as more fully set forth in the Employment Agreements.

Additionally, the non-solicitation provisions of the Employment Agreements prohibit the Officer from soliciting for employment any employee of the Company or any person who was an employee of the Company in the 90-day period before such solicitation. This prohibition applies during the Officer’s employment with the Company and for six months following the termination of the Officer’s employment and extends to offers of employment for his own account or benefit or for the account or benefit of any other person, firm or entity, directly or indirectly.

The foregoing descriptions are not complete and are qualified in their entirety by reference to the full text of the Employment Agreements, copies of which are attached as Exhibits 10.1 10.2, 10.3, 10.4 and 10.5 to this Current Report on Form 8-K and are hereby incorporated herein by reference.
