FIRST AMENDMENT TO LOAN AND SECURITY AGREEMENT

Exhibit 10.61

FIRST AMENDMENT TO LOAN AND SECURITY AGREEMENT

This First Amendment (this “Amendment”) is made as of this 16th day of March, 2005 to that certain Loan and Security Agreement dated December 14, 2004 (the “Loan Agreement”) among Citizens Bank of Massachusetts (the “Bank”) and each of VIISAGE TECHNOLOGY, INC., a Delaware corporation, TRANS DIGITAL TECHNOLOGIES CORPORATION, a Delaware corporation, IMAGING AUTOMATION, INC., a Delaware corporation and BIOMETRICA SYSTEMS, INC., a New Hampshire corporation (hereinafter collectively referred to as the “Borrower”). Capitalized terms used and not defined in this Amendment shall have the meanings ascribed to them in the Loan Agreement.

RECITALS

Borrower has advised Bank that Borrower was not in compliance with the Minimum EBITDA covenant contained in Section 15(c) of the Loan Agreement as of its fiscal year end December 31, 2004 and has requested that Bank agree to waive compliance with such covenant. Borrower has further requested that Bank agree to (i) modify certain other financial covenants contained in Section 15 of the Loan Agreement and (ii) make certain other modifications to the Loan Agreement.

Bank is amenable to so waiving compliance with the Minimum EBITDA Covenant at December 31, 2004 and to so modifying the Loan Agreement, but only on the terms and conditions contained in this Amendment.

AGREEMENT

In consideration of the foregoing, of the undertakings of Borrower and Bank herein and for other good and valuable consideration, receipt and sufficiency of which is hereby acknowledged, the parties hereto hereby agree as follows:

1. Section 5(c) of the Loan Agreement is hereby deleted in its entirety and replaced with the following text:

“(c) The term “Credit Limit” as used herein shall mean an amount equal to Twenty-Five Million and 00/100 ($25,000,000.00) Dollars, up to Ten Million ($10,000,000.00) Dollars of which (the “L/C Limit”) shall be available for standby Letters of Credit, as provided below, and up to Two Million and 00/100 ($2,000,000.00) Dollars of which (the “FX Limit”) shall be available as a reserve for settlement risk on foreign exchange transactions. For purposes of the foregoing, the credit exposure to be reserved against the FX Limit with respect to any foreign exchange contract shall be equal to the Applicable Percentage of the face amount of such foreign exchange contract (expressed in US Dollars). The Applicable Percentage is a percentage determined by Bank in its discretion from time to time with respect to each foreign exchange transaction based upon the currency and length of contract, and is initially agreed to be up to 15.0%.

This Amendment shall be binding upon Bank and Borrowers, and their representatives, successors, and assigns, and shall inure to the benefit of Bank and Borrowers and their respective successors and assigns. This Amendment and all documents, instruments, and agreements executed in connection herewith incorporate all of the discussions and negotiations among Borrowers and Bank, either expressed or implied, concerning the matters included herein and in such other documents, instruments and agreements, any statute, custom, or usage to the contrary notwithstanding.

17. If any clause or provision of this Amendment is determined to be illegal, invalid or unenforceable under any present or future law by the final judgment of a court of competent jurisdiction, the remainder of this Amendment will not be affected thereby. It is the intention of the parties that if any such provision is held to be invalid, illegal or unenforceable, there will be added in lieu thereof an enforceable provision as similar in terms to such provision as is possible, and that such added provision will be legal, valid and enforceable.

18. This Amendment is delivered to Bank in The Commonwealth of Massachusetts and it is the desire and intention of the parties that this Amendment and the Loan Documents be in all respects interpreted according to the laws of The Commonwealth of Massachusetts. Borrowers each specifically and irrevocably consent to the personal and subject matter, jurisdiction and venue of any court of The Commonwealth of Massachusetts sitting in the counties of Suffolk or Middlesex or in the District Court of the United States for the District of Massachusetts with respect to all matters concerning this Amendment or the Loan Documents or the enforcement of any of the foregoing.

19. This Amendment may be executed in one or more counterparts, each of which will be deemed an original document, but all of which will constitute a single document. This Amendment will not be binding on or constitute evidence of a contract between the parties until such time as a counterpart of this document has been executed by each of the parties and delivered to Bank.
