1.Amendments to the Employment Agreement. The Employment Agreement is hereby amended as set forth below.

(a)Amendment to Section 5(a) of the Employment Agreement. The first (1^st)

sentence of Section 5(a) of the Employment Agreement is hereby amended and restated as follows:

Executive shall make an I.R.C. Section 83(b) election (the "Election") in 2015 with regard to the Subsequent Restricted Stock Award to accelerate Executive's recognition of the income from the Subsequent Restricted Stock Award such that it is treated as income to Executive in the year of grant for state and federal income tax purposes. In addition to all other compensation due to Executive

hereunder, the Company shall also pay Executive a bonus, with respect to each applicable year, in an amount equal to the tax liability Executive incurs as a result of the vesting of the Initial Restricted Stock Award and making the Election with respect to the Subsequent Restricted Stock Award (regardless of whether such vesting occurs as result of the passage of time or pursuant to Section 7(b)(iii) of this Agreement) (each, a "Tax Payment Bonus"), which payment shall be "grossed up" to compensate for the additional tax liability Executive incurs as a result of receiving the Tax Payment Bonus such that the Company fully and completely reimburses Executive for any state and federal income tax liability Executive incurs as a result of the vesting of the Initial Restricted Stock Award and making the Election with respect to the Subsequent Restricted Stock Award.

(c)Amendment to Section 5(c) of the Employment Agreement by Adding a New Final Sentence. The following sentence is added to the end of Section 5(c) and constitutes Section 5(c)'s final sentence:

Unless required to be paid earlier pursuant to Section 7(d) of this Agreement, the Tax Payment Bonus shall be payable on the date on which annual bonuses are paid to senior executives generally, but in no event later than two-and-one-half (2½) months following the end of the fiscal year in which the vesting of the Restricted Stock Award occurs.

To the extent any portion of the Restricted Stock Awards and the Common Stock underlying the Warrant are not fully vested as of the Termination Date: (A) such vesting periods shall automatically accelerate such that the Restricted Stock Awards and the Warrant shall be fully vested as of the Termination Date; and (B) Executive shall receive a lump sum amount equal to the Tax Payment Bonus in connection with the vesting of the Restricted Stock Awards; and

2.Existing Terms. The existing terms and conditions of the Employment Agreement shall remain in full force and effect except as such terms and conditions are specifically amended by, or in conflict with, the terms of this Amendment.
