mitigation provisions of this Section 4.2, the Trustee shall pay to Employee out of the Trust the following: (a) fifty-four and fifty-five hundredths percent (54.55%) of the total amount originally deposited in the Trust on the first day of the seventh month following the Termination Event or Sale of Company Termination Event; and (b) the remaining forty-five and forty five hundredths percent (45.45%) of the total amount originally deposited in the Trust in six (6) equal installments on the last day of each month commencing on the last day of the seventh month following the Termination Event or Sale of Company Termination Event. Employee agrees that in the event he earns any salary, consulting fees, signing bonuses, or other compensation income from a party other than the Company during the twelve (12) month period following the Termination Event or Sale of Company Termination Event (“MITIGATION PERIOD”), that the Company shall be entitled to reduce its Severance Payment obligation, net of withholding, by the amount of such payments received by Employee net of withholding (“OTHER NET COMPENSATION”) and that Employee will promptly notify the Company and the Trustee of his receipt of Other Net Compensation. If the Company and the Trustee receive such notice or otherwise verify that Employee has received Other Net Compensation during the Mitigation Period, the Trustee shall deliver to the Company from the Trust Deposit an amount equal to the Other Net Compensation received by Employee during the Mitigation Period. Once disbursed by the Trustee, Employee shall be under no obligation to reimburse the Company any of those disbursed amounts unless Employee has failed to disclose the receipt of any Other Net Compensation during the Mitigation Period. Any scheduled disbursements due from the Trustee shall be offset and reduced by the amount of Other Net Compensation received by Employee during the Mitigation Period. The Employee and Company will enter into a suitable trust agreement with the Trustee to carry out the provisions of this Section 4.2. Employee is under no duty to seek employment or other sources of compensation income during the Mitigation Period.

SECTION 5. SALE OF NOTES AND ACQUISITION BONUS; GROSS-UP AMOUNT

5.1 SALE OF NOTES AND ACQUISITION BONUS

(a) The Company has adopted an Amended and Restated the Company Bonus Program, adopted as of the date hereof (the “BONUS PROGRAM”). The Company hereby agrees that Employee shall be entitled to receive from the moneys allocated to the Bonus Program tied to the sale of Convertible Notes (“CNBP”) a payment equal to five percent (5%) of the Sale of Note Proceeds. In addition, the Company hereby agrees that Employee shall be entitled to receive from the moneys allocated to the Management and Employee Bonus Pool (the “MBP”) a payment equal to five percent (5%) of the Net Proceeds to Securityholders.

Employee hereby acknowledges that the percentage of Sale of Note Proceeds and percentage of Net Proceeds to Securityholders that he receives under this paragraph plus any amounts under Section 5.2 is the total amount to be paid to Employee under the Bonus Program and Section 5.2. Notwithstanding the foregoing, all amounts payable hereunder to Employee from MBP shall be reduced by an amount equal to the value of the spread between the option exercise price of the Employee’s options and the per share price to be distributed to the common shareholders in connection with the Sale of the Company for those options held by Employee that are “in-the-money”. By way of illustration, if the Acquisition Price is $21,000,000 and the Net Proceeds to Common Stockholders is $19,000,000, then the 5% payable to Employee would be applied to the entire $19,000,000 amount. The Employee would receive $950,000 as an acquisition bonus, less an In-The-Money Option amount as calculated in Section 3 of the Bonus Program (provided the shares underlying the Employee’s In-the-Money Options are purchased by the acquiring party in connection with the Sale of the Company), plus the gross-up amount specified in Section 5.2.

(b) Should a Current Securityholder Acquiring Party be the purchaser in a Sale of the Company and that party does not receive, or waives its right to receive, all or any portion of the purchase price otherwise payable to Securityholders, then and only in that event, the Net Sales Proceeds to Securityholders shall include the value of the shares of Company stock held by such Current Securityholder Acquiring Party based on the same value per share that will be paid or distributed to Securityholders owning the same class or series of shares, Convertible Notes or other convertible securities (the “Value Adjustment”). The payment of bonuses applicable to this Value Adjustment is an obligation of the Company and shall not reduce the amount of Net Proceeds to Securityholders otherwise payable to stockholders other than the Employee and other participants in the Bonus Pool.

(c) The payments made under this Section 5.1 will be made within five (5) business days of the Company’s receipt of any net proceeds with respect to the CNBP and within five (5) business days from receipt of any payment in connection with a Sale of the Company with respect to the MBP.

- 7 -

5.2 GROSS-UP AMOUNT. The Company shall provide an additional payment to the Employee (“GROSS-UP PAYMENT”) to cover all applicable excise taxes payable by the Employee upon the distribution of any Bonus Program proceeds and the value of the Employee’s stock options subject to such excise taxes. The Gross-Up Payment shall be payable from the consideration allocated to the CNBP and/or the MBP. The Company and Employee hereby agree, notwithstanding the foregoing that the total amount paid to Employee under Section 5, including the Gross-Up Payment, shall not exceed six and one quarter percent (6.25%) of the Sale of Note Proceeds and Net Proceeds to Securityholders and the value of the Employee’s stock options subject to excise taxes.

5.3 SEVERANCE BENEFITS. The payments under this Section 5 do not include or replace any Severance Payment that may be payable to or received by the Employee upon the occurrence of a Termination Event or a Sale of the Company Termination Event, as described in Section 4.

SECTION 6. PARTIAL INVALIDITY

The invalidity or unenforceability of a particular provision of this Agreement shall not affect the other provisions hereof, and this Agreement shall be construed in all respects as if such invalid or unenforceable provisions were omitted.

SECTION 7. TERMINATION OF AGREEMENT

This Agreement shall terminate upon the earlier of: (i) the date the Employee is terminated for Cause or resigns without Good Reason; (ii) twelve months and one day after a Sale of the Company has occurred; or (iii) the fourth (4th) anniversary of this Agreement. The obligations of Employee under Section 4.2 and 4.4 will survive termination of this Agreement.

SECTION 8. NO ORAL MODIFICATION

Except as set forth in Section 9 below, no modification, amendment or waiver of any of the provisions of this Agreement shall be deemed effective unless made in writing specifically referring to this Agreement and duly signed by each party hereto.

SECTION 10. GOVERNING LAW/VENUE

This Agreement shall be governed and construed by the provisions hereof and in accordance with the laws of the State of Florida applicable to agreements to be performed in the State of Florida. Venue for any litigation stemming from the construction and operation of this Agreement shall be in Brevard County, Florida.

SECTION 11. ASSIGNABILITY

This Agreement may not be assigned by either party, in whole or in part, without the prior written consent of the party to be charged; provided, however, that such prior written consent shall not be unreasonably withheld.

SECTION 12. BINDING EFFECT

This Agreement shall be binding on the successors and assigns of either party hereto, except that the Company shall not be relieved of any liability hereunder upon the assignment, in connection with a Sale of the Company or otherwise, of this Agreement.
