As disclosed in the Original Filing, the Company appointed current interim Chief Executive Officer Daniel D. Greenwell to serve as President and Chief Executive Officer. This Current Report on Form 8-K/A amends the Original Filing to (i) set forth the description of the terms of the employment agreement between Mr. Greenwell and the Company, entered into and effective as of December 31, 2015 (the “Employment Agreement”) and (ii) describe the terms of a restricted stock award granted to Mr. Greenwell in connection with his appointment as President and Chief Executive Officer, made pursuant a Restricted Stock Agreement by and between the Company and Mr. Greenwell, dated December 31, 2015 (the “Restricted Stock Agreement”).

Employment Agreement

The Employment Agreement provides that Mr. Greenwell: (i) will serve as the President and Chief Executive Officer of the Company for an initial term of three (3) years with the Employment Agreement automatically renewing for successive one-year periods on the anniversary of the effective date until terminated by either party, as described below; (ii) will receive an annual base salary of at least $800,000; (iii) will be eligible to receive a target annual cash performance bonus equal to 62.5% of Mr. Greenwell’s base salary (the “target bonus”) and a maximum cash bonus equal to 125% of Mr. Greenwell’s base salary (the “maximum bonus”), depending on the Company’s achievement of performance criteria, as determine by the Board; (iv) will receive an annual equity award of restricted stock that has a value of not less than 337.5% of Mr. Greenwell’s base salary (the first grant described below); and (v) will receive four (4) weeks of paid vacation per calendar year.

The Employment Agreement provides that Mr. Greenwell will be eligible to receive benefits should his employment with the Company be terminated (i) due to death or disability, (ii) by the Company without Cause (as defined in the Employment Agreement), or (iii) by Mr. Greenwell for Good Reason (as defined in the Employment Agreement). If Mr. Greenwell’s employment with the Company is terminated due to death or disability, (1) Mr. Greenwell will receive a lump sum payment equal to a pro rata portion of his annual bonus based on actual company performance for the year of termination, paid at the same time such bonuses are paid to all employees generally and (2) all outstanding equity awards will vest pro rata as of the date of termination. If Mr. Greenwell’s employment is terminated by the Company without Cause or by Mr. Greenwell for Good Reason, Mr. Greenwell will receive (a) a lump sum payment equal to a pro rata portion of his annual bonus based on actual company performance for the year of termination, paid at the same time such bonuses are paid to all employees generally, (b) a lump sum payment equal to two (2) times his base salary and target bonus (three (3) times base salary and target bonus should the termination occur within twenty-four (24) months following a Change in Control) payable on the first pay date following execution of a release of claims, (c) accelerated vesting of all outstanding equity awards as of the date of termination, and (d) continuation of health benefits for eighteen (18) months on the same economic terms applicable prior to his termination. All severance or termination benefits payable to Mr. Greenwell under the Employment Agreement are dependent on his execution and delivery of a release of claims within sixty (60) days following the date of termination. Following termination of employment, Mr. Greenwell will be subject to non-compete and non-solicitation restrictions for a period of twenty-four (24) months.
