TO CREDIT AGREEMENT

THIS FIRST AMENDMENT TO CREDIT AGREEMENT (this “Amendment”), is made and entered into as of this 6th day of February, 2004, with an effective date as set forth in Section 6 hereof, by and among DRS TECHNOLOGIES, INC., a corporation organized under the laws of Delaware (the “Borrower”), those certain subsidiaries of the Borrower party to the Subsidiary Guaranty Agreement referred to below (the “Subsidiary Guarantors”), the Lenders party to the Credit Agreement referred to below (the “Lenders”) pursuant to the authorization (in the form attached hereto as Annex A, the “Authorization”), WACHOVIA BANK, NATIONAL ASSOCIATION, as Administrative Agent for the Lenders (the “Administrative Agent”), BEAR STEARNS CORPORATE LENDING INC., as Syndication Agent for the Lenders (the “Syndication Agent”), and FLEET NATIONAL BANK, as Documentation Agent for the Lenders (the “Documentation Agent”). WACHOVIA CAPITAL MARKETS, LLC and BEAR, STEARNS & CO. INC. acted as Co-Lead Arrangers in connection with the Credit Agreement referred to below and this Amendment.

Statement of Purpose

The Lenders agreed to extend certain credit facilities to the Borrower pursuant to the Second Amended and Restated Credit Agreement dated as of November 4, 2003 by and among the Borrower, the Lenders, the Administrative Agent, the Syndication Agent and the Documentation Agent (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”). In connection therewith, certain of the Subsidiaries of the Borrower executed the Subsidiary Guaranty Agreement dated as of September 28, 2001 in favor of the Administrative Agent for the ratable benefit of itself and the other Lenders (as reaffirmed by the Reaffirmation Agreement dated as of November 4, 2003 and as further amended, restated, supplemented or otherwise modified from time to time, the “Subsidiary Guaranty Agreement”).

The parties now desire to amend or modify certain provisions of the Credit Agreement in certain respects on the terms and conditions set forth below.

NOW THEREFORE, for good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, the parties hereto agree as follows:

1. Capitalized Terms. All capitalized undefined terms used in this Amendment shall have the meanings assigned thereto in the Credit Agreement.

2. Amendments to the Credit Agreement. The Credit Agreement is hereby modified as follows:

(a) Amendments to Existing Definitions. The definition of the following defined terms which are set forth in Section 1.1 of the Credit Agreement are hereby amended in their entirety as follows:

“Additional Term Loan Effective Date” means (i) with respect to the First Additional Term Loans, the First Amendment Effective Date and (ii) with respect to any other Additional Term Loans, the date, which shall be a Business Day, on or before the Term Loan Maturity Date, but no earlier than thirty (30) days after any Increase Notification Date (unless otherwise agreed to by the Administrative Agent), on which each of the Increase Lenders make any Additional Term Loans to the Borrower pursuant to Section 4.6.

“Notes” means the collective reference to the Revolving Credit Notes, the Term Notes and the Swingline Note, and “Note” means any of such Notes. From and after the First Amendment Effective Date, some or all of the Loans may not be evidenced by Notes, and consequently, with respect to any Lender that has made Loans not evidenced by Notes, any reference to a Revolving Credit Note, a Term Note, a Swingline Note or a Note, shall, as applicable, be deemed to be a reference to the related Obligations that would be represented by such Revolving Credit Note, such Term Note, such Swingline Note or such Note had such Lender elected to have its Loans represented by Notes.

(b) Amendment to Add New Definitions. Section 1.1 of the Credit Agreement is hereby amended by adding the following definitions thereto in the appropriate alphabetical order:

“First Additional Term Loans” means the Additional Term Loans which were made to the Borrower by the Lenders on the First Amendment Effective Date.

“First Amendment” means the First Amendment to Credit Agreement dated as of February 6, 2004 by and among the Borrower, the Subsidiary Guarantors, the Lenders, the Administrative Agent, the Syndication Agent and the Documentation Agent.

“First Amendment Effective Date” means February 6, 2004.

(c) Amendment to Section 4.3(b). The proviso to subsection (b) of Section 4.3 of the Credit Agreement is hereby deleted in its entirety and the following is substituted in lieu thereof:

provided that (i) if not sooner paid, such Additional Term Loans shall be paid in full, together with accrued interest thereon, on the Term Loan Maturity Date and (ii) the amounts of individual installments may be adjusted pursuant to Section 4.4.

(d) Amendments to Section 4.6. Section 4.6 of the Credit Agreement is hereby amended by:

(i) deleting subsection (a) in its entirety and inserting the following in lieu thereof:

(a) Subject to the conditions set forth below, the Borrower shall have the option, exercisable on no more than three (3) occasions following the Closing Date until the Term Loan Maturity Date, to incur additional indebtedness under this Agreement in the form of an increase of the Term Loan Commitment of up to Three Hundred Thirty-Five Million Four

Hundred Ten Thousand Dollars ($335,410,000). The Borrower, by providing an Increase Notification, may request that additional Term Loans be made on the applicable Additional Term Loan Effective Date pursuant to such increase in the Term Loan Commitment (each such additional Term Loan, an “Additional Term Loan”, and collectively, the “Additional Term Loans”). The Borrower, the Administrative Agent and the Lenders hereby agree and acknowledge that the Borrower first exercised the option set forth in this subsection (a) on the First Amendment Effective Date in connection with the incurrence of First Additional Term Loans in the amount of $235,410,000.

(ii) by adding the following parenthetical at the end of clause (iv) in subsection (c):

(provided that the Administrative Agent and the Lenders agree that the financial projections and the financial condition certificate delivered as of the Closing Date shall be sufficient to satisfy the requirements of this Section 4.6(c)(iv) with respect to the First Additional Term Loans)

(iii) deleting clause (vii) in subsection (c) in its entirety and inserting the following in lieu thereof:

(vii) the amount of such increase in the Term Loan Commitment and any Additional Term Loans obtained thereunder shall not be less than a minimum principal amount of $10,000,000, or any whole multiple of $5,000,000 in excess thereof (unless otherwise agreed to by the Administrative Agent);

(iv) deleting subsection (f) in its entirety and inserting the following in lieu thereof:

(f) Within five (5) Business Days after receipt of notice, upon the request of any existing Lender or with respect to any Lender not theretofore a Lender, the Borrower shall execute and deliver to the Administrative Agent, in exchange for any surrendered Term Note of any such Lender, a new Term Note to the order of such Lender in amounts equal to the Term Loan Commitment of such Lender as set forth in the Register. Such new Term Note shall be in an aggregate principal amount equal to the aggregate principal amount of the Term Loan Commitment of such Lender, shall be dated as of the applicable Additional Term Loan Effective Date and shall otherwise be in substantially the form of the existing Term Notes. Each surrendered Term Note and/or Term Notes shall be canceled and returned to the Borrower.

(e) Amendment to Section 9.12. Section 9.12 of the Credit Agreement is hereby deleted in its entirety and the following is substituted in lieu thereof:

SECTION 9.12 Use of Proceeds. The Borrower shall use the proceeds of the Extensions of Credit (a) to finance the IDT Merger (including the refinancing of certain existing Debt of IDT) (b) to finance Permitted Acquisitions, (c) to refinance existing indebtedness of the Borrower, (d) to finance Capital Expenditures of the Borrower, and (e)

for working capital and general corporate requirements of the Borrower and its Restricted Subsidiaries, including the payment of certain fees and expenses incurred in connection with the IDT Merger and the other transactions contemplated hereby. Notwithstanding the foregoing, the proceeds of the First Additional Term Loans shall be used to refinance the Initial Term Loans on the First Amendment Effective Date.

3. Additional Term Loan Agreement. The Applicable Margin and the terms for repayment of the First Additional Term Loans are set forth on Schedule 1 attached hereto and in Articles IV and V of the Credit Agreement; provided that the terms set forth on Schedule 1 attached hereto shall control to the extent such terms conflict with the terms of Articles IV and V of the Credit Agreement. For the purpose of Section 4.6 of the Credit Agreement, this Amendment shall constitute the Additional Term Loan Agreement with respect to the Additional Term Loans being made on the date hereof.

4. Conversion of the Initial Term Loans into Additional Term Loans.

(a) The parties hereby agree that upon the First Amendment Effective Date, the Initial Term Loans of each Lender that will hold First Additional Term Loans on the First Amendment Effective Date (each such Lender, a “Converting Lender”) shall be converted into First Additional Term Loans, in each case in the amounts and the percentages, as applicable, set forth in the Register for such Converting Lender. In the event that, immediately after giving effect to the payments, conversions and reallocations on the Conversion Date as contemplated by this Section 4(a), the outstanding principal amount of a Converting Lender’s First Additional Term Loans will exceed the outstanding principal amount of such Converting Lender’s Initial Term Loans immediately prior to giving effect to such payments, conversions and reallocations, then such Converting Lender shall make an advance in an amount equal to such excess. Furthermore, the Administrative Agent shall make such reallocations of outstanding Term Loans of each Converting Lender as are necessary in order that the First Additional Term Loans of such Converting Lender reflect such Converting Lender’s Term Loan Commitment, in each case as set forth on the Register immediately after giving effect to the payments, conversions and reallocations contemplated in this Section 4(a).

(b) As of the First Amendment Effective Date, after giving effect to the payments, conversions and reallocations described in Section 4(a), the aggregate outstanding amount of the First Additional Term Loans shall be $235,410,000. The outstanding Initial Term Loans of all Lenders other than the Converting Lenders (the “Departing Lenders”) shall be repaid in full from the proceeds of the First Additional Term Loans and terminated and each such Departing Lender shall cease to be a Lender with respect to Term Loans under the Credit Agreement. In addition, on the First Amendment Effective Date, the Initial Term Loans shall be entirely re-evidenced and replaced with the First Additional Term Loans. The Borrower hereby agrees that after the First Amendment Effective Date, neither the Administrative Agent, the Syndication Agent, the Documentation Agent nor any Lender shall have any further obligations with respect to the Initial Term Loans.

(c) All Term Notes issued by the Borrower to any Lender in connection with the Initial Term Loans shall be canceled and be promptly returned to the Borrower. Upon the request of any

Lender in connection with the First Additional Term Loans, the Borrower shall execute and deliver to such Lender new Term Notes.

(d) To the extent any conversion, reallocation or prepayment provided in this Section 4 is deemed to conflict with any of the provisions of Articles IV or V of the Credit Agreement (including, without limitation, Section 4.6(d)), any such conflicting provisions are hereby waived for purposes of this Amendment.

(e) The events and transactions described and contemplated in this Section 4 are not intended to, and shall not, constitute a novation of the Credit Agreement or any of the indebtedness incurred in connection therewith, including, without limitation, any Obligations.

5. Consent.
