                  SECOND AMENDMENT, LIMITED WAIVER AND CONSENT

     THIS SECOND AMENDMENT, LIMITED WAIVER AND CONSENT dated as of August 10,
2005 (this "Amendment"), by and among EMS TECHNOLOGIES, INC., a Georgia
corporation (the "Borrower"), the Lenders listed on the signature page hereof
and SUNTRUST BANK, in its capacity as the Administrative Agent (the
"Administrative Agent").

                              W I T N E S S E T H:

      WHEREAS, the Borrower, the Lenders and the Administrative Agent entered
into that certain U.S. Revolving Credit Agreement dated as of December 10, 2004,
as amended by that certain First Amendment to U.S. Revolving Credit Agreement
dated as of February 11, 2005 (as so amended, the "Credit Agreement");

      WHEREAS, the Borrower, the Lenders and the Administrative Agent desire to
amend the Credit Agreement in certain respects on the terms and conditions
contained herein;

      WHEREAS, the Borrower has informed the Administrative Agent and the
Lenders that the Borrower has failed or will fail to comply with the financial
covenants contained in Sections 6.1 and 6.2 of the Credit Agreement for the
fiscal quarter of the Borrower ending on or about June 30, 2005, resulting in an
Event of Default under Sections 8.1(d) and 8.1(o) of the Credit Agreement (the
"Specified Defaults"), which failure is solely a consequence of the write-down
in the book value of the assets being sold in connection with the Canadian Sale
and Prepayment Event (the "Asset Write-Down");

      WHEREAS, the Borrower has informed the Administrative Agent and the
Lenders that the Borrower intends to sell the assets of the business currently
conducted by the Borrower's EMS Satellite Networks division from leased
facilities located in Montreal, Quebec (the "SatNet Assets") and has requested
that the Administrative Agent and the Lenders consent to the sale of the SatNet
Assets as required under Section 7.6 of the Credit Agreement; and

      WHEREAS, the Borrower has requested that the Administrative Agent and the
Lenders waive the Specified Defaults, and the effects thereof, under the Credit
Agreement and consent to the sale of the SatNet Assets.

      NOW, THEREFORE, for and in consideration of good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged by
the parties hereto, the Lenders, the Administrative Agent and the Borrower
hereby agree as follows:

1. DEFINED TERMS. Capitalized terms which are used herein without definition and
which are defined in the Credit Agreement shall have the same meanings ascribed
to them as in the Credit Agreement.

2. AMENDMENTS. (a) The Credit Agreement is hereby amended by adding the
following sentence at the end of the defined term "CONSOLIDATED NET INCOME"
contained in Section 1.1 thereof:

<PAGE>

            "Notwithstanding the foregoing, any net income (or loss)
      attributable to the sale of the SatNet Assets and/or the assets giving
      rise to the Canadian Sale and Prepayment Event that are otherwise included
      in Consolidated Net Income during the period of determination shall be
      excluded if such assets are sold during such period."

      (b) The Swingline Lender and the Borrower agree that (i) there shall be no
minimum amount for any Borrowings of Swingline Loans and (ii) there shall be no
minimum amount for the prepayment of any Swingline Loan. Accordingly, footnote 8
to Exhibit 2.5 is hereby deleted.

3. LIMITED WAIVER. At the request of the Borrower, but subject to the
satisfaction of the conditions precedent set forth in Section 5 below, the
Lenders hereby waive the Specified Defaults arising solely by virtue of the
Asset Write-Down; provided that the Asset Write-Down does not exceed
$12,000,000. The Borrower acknowledges and agrees that the waiver contained in
the foregoing sentence shall not waive (or be deemed to be or constitute a
waiver of) any other covenant, term or provision in the Credit Agreement or
hinder, restrict or otherwise modify the rights and remedies of the Lenders and
the Administrative Agent following the occurrence of any other present or future
Default or Event of Default (whether or not related to the Specified Defaults)
under the Credit Agreement or any other Loan Document.

4. CONSENT. At the request of the Borrower, but subject to the satisfaction of
the conditions precedent set forth in Section 5 below, the Lenders hereby
consent to the sale of the SatNet Assets; provided, that (i) the Borrower
receives cash consideration in an amount not less than $16,000,000, (ii) the Net
Proceeds of the sale of the SatNet Assets are applied in accordance with Section
2.14 of the Credit Agreement, and (iii) such sale shall be completed by December
31, 2005. The Borrower acknowledges and agrees that the consent contained in the
foregoing sentence shall not waive or amend (or be deemed to be or constitute an
amendment to or waiver of) any other covenant, term or provision in the Credit
Agreement or hinder, restrict or otherwise modify the rights and remedies of the
Lenders and the Administrative Agent following the occurrence of any present or
future Default or Event of Default (whether or not related to the sale of the
SatNet Assets) under the Credit Agreement or any other Loan Document.

5. EFFECTIVENESS OF AMENDMENT. The effectiveness of this Amendment is subject to
