HANS KOBLER EMPLOYMENT AGREEMENT

This First Amendment (this “Amendment”) to the Employment Agreement, dated as of October 1, 2005 (the “Agreement”), by and between Hans Kobler (“Employee”) and ICx Technologies, Inc. (the “Company”), is dated as of April 26, 2007. All capitalized terms used but not defined herein have the meanings set forth in the Agreement.

WHEREAS, the Employee desires to amend the terms of the Agreement; and

WHEREAS, as consideration for such amendment, the Employee has agreed to enter into an additional employment agreement with the Company effective as of October 1, 2007 (the “Employment Extension Agreement”);

WHEREAS, the Company will derive significant benefit from the Employment Extension Agreement;

NOW THEREFORE, for the consideration recited above and other good and valuable consideration the parties hereby amend the Agreement effective as of April 26, 2007 as follows:

1. The following definition shall be added to the Agreement:

“Severance Base Salary” shall mean a base salary at an annual rate of $750,000.

2. Section 9 of the Agreement shall be deleted in its entirety and replaced with the following:

9. Severance. Upon termination of employment for any reason, Employee shall receive payment of (i) his Base Salary, as then in effect, earned but unpaid through the date of termination of employment and (ii) all accrued vacation, expense reimbursements and any other benefits (other than severance benefits, except as provided below) due to Employee through the date of termination of employment in accordance with established Company plans and policies or applicable law (the “Accrued Obligations”). In addition, the following will apply:

(a) Involuntary Termination or Resignation for Good Reason. If (i) the Company terminates Employee’s employment with the Company for reasons other than Cause, death or Disability, or (ii) the Employee resigns for Good Reason, then, subject to Employee’s compliance with Section 9(e), Employee shall be entitled to receive continuing payments of severance pay (less applicable withholding taxes) at a rate equal to his Severance Base Salary rate, as then in effect, for a period of twelve (12) months from the date of such termination (herein after the “Severance Term”), to be paid periodically in accordance with the Company’s normal payroll policies. If the Employee accepts other employment or engages in his own business prior to the last date of the Severance Term, the Employee shall forthwith notify the Company, but such other activity shall not diminish

the Company’s obligation under this Section 9(a); provided that if Employee continues to be employed in any capacity by a successor entity following a Chance of Control, the severance pay that would otherwise be payable under this Section 9(a) shall be reduced by the amount of base compensation and guaranteed bonus (if any) the Employee receives in such capacity during or attributable to the Severance Term.

(b) Voluntary Termination; Termination for Cause. If Employee’s employment with the Company terminates (i) voluntarily by Employee for other than Good Reason, or (ii) for Cause by the Company, then Employee will only be eligible for his Accrued Obligations.

(c) Extended Severance Term Election. If Employee’s employment with the Company terminates for any reason during the Term, the Company shall have the right in its discretion to pay the Employee severance pay for a period of up to twelve (12) months less the Severance Term (the “Extended Severance Term”), in the same manner provided in subsection (a) hereof. If the Company elects to pay such severance pay during any Extended Severance Term, the Employee shall be bound under the noncompetition provisions of Section 9 of the Supplemental Agreement and any comparable provision of any amended or successor agreement (the “Noncompete Provisions”) for such Extended Severance Term. The Company shall give the Employee written notice of its election to pay additional severance pay, and the time period for the Extended Severance Term, under this provision within 10 business days following the Employee’s termination. If the Company fails to provide such notice, or fails to pay severance pay as set forth in this Section 9(c), the Employee shall be discharged from any further obligations under the Noncompete Provisions at the end of the earlier of the end of the Term of this Agreement or the Severance Term (if any).

(d) Termination by Death or Disability. If the Employee’s employment is terminated by disability or death, the Employee or the Employee’s estate as the case may be shall be entitled to receive only the Accrued Obligations.
