         has with Lender;

                  (c) Any representation or statement made or furnished to

                  (d) A receiver is appointed for any part of Borrower's
         property, Borrower makes an assignment for the benefit of creditors, or
         any proceeding is commended either by Borrower or against Borrower
         under any Bankruptcy or insolvency laws.

         5. Remedies upon Default. Upon an Event of Default or upon the
occurrence of any other event of default under the Security Agreement or any
other any other agreement Borrower has executed in conjunction with this Note,
the entire amount due under this Note, including the principal, interest and all
Handling Fees and all other sums paid or advanced by Lender to or on behalf of
the Borrower pursuant to the terms of this Note, shall at the option of Lender
(or, in the case of a Bankruptcy Event, automatically) become immediately due
and payable without further notice or demand, and Lender may forthwith exercise
the remedies available to Lender at law or in equity, as well as those remedies
set forth in this Note, Security Agreement and any other any other agreement
Borrower has executed in conjunction with this Note, and one or more executions
may forthwith issue on any judgment or judgments obtained by virtue thereof. All
of the terms, covenants and provisions contained in the Security Agreement and
any other any other agreement Borrower has executed in conjunction with this
Note are hereby made part of this Note to the same extent and with the same
force and effect as if they were fully set forth herein. The rights, remedies
and powers of Lender under this Note are cumulative and concurrent and not
exclusive of any rights or remedies that Lender would otherwise have, and may be
pursued successively or together against the Borrower, or any security for the
performance of this Note, in Lender's sole and absolute discretion.

         6. Security for Obligation. This Note is secured by that certain
Security Agreement of even date ("Security Agreement") from Borrower granting a
first-priority lien in favor of Lender of that certain account receivable in the
amount of $221,433.64 payable by Raytheon Technical Services Co LLC to Borrower
(the "Account Receivable") as more particularly described in the Security
Agreement executed concurrently herewith. Borrower shall have obtained prior to
or concurrently with the execution of this Note the agreement and consent of any
and all senior secured lien holder to subordinate any security interest in the
Account Receivable, to Lender's first-priority lien. Borrower further agrees to
make all filings and take such other action necessary or desirable to protect
and perfect such the first-priority lien of Lender in the Account Receivable,
including without limitation the filing of such UCC-1 financing statements in
favor of the Lender and the filing of any such UCC-2 Financing Statement
Amendments reflecting the subordination of all senior lien holders.

         7. Usury Savings Clause. If, by the terms of this Note, the Borrower is
at any time required or obligated to pay interest at a rate in excess of such
maximum rate, the rate of interest under this Note shall be deemed to be
immediately reduced to such maximum rate and interest payable hereunder shall be
computed at such maximum rate and the portion of all prior interest payments in
excess of such maximum rate shall be applied to reduce (and shall be deemed to
have been payments in reduction of )the principal balance of the Note.

         8. Notices. Any notice, payment or other communication required or
permitted hereunder shall be expressed in writing and sent by certified or
registered mail, return receipt requested, to their respective parties at the
