a direct wholly-owned subsidiary of Aeroflex Holding Corp. (&ldquo;Aeroflex&rdquo;), entered into Amendment No. 1 (the &ldquo;Amendment&rdquo;)
to the Credit and Guaranty Agreement, dated as of May 9, 2011, by and among Aeroflex, Borrower, certain subsidiaries of Borrower,
as guarantors thereto, the lenders party thereto and JPMorgan Chase Bank, N.A., as administrative agent (the &ldquo;Credit Agreement&rdquo;).</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">The Amendment increases flexibility under
the total leverage ratio covenant. Pursuant to the Amendment, the maximum total leverage ratio (as defined in the Credit Agreement)
permitted as of June 30, 2012 will be 5.75 to 1.00, which periodically decreases to 3.50 to 1.00 on March 31, 2015. The Amendment
also increases the interest rate payable with respect to outstanding borrowings under the loan facility by 1.5% to either: (i)
the base rate (as defined in the Credit Agreement), plus an applicable margin of 3.5%, or (ii) the adjusted LIBOR rate (as defined
in the Credit Agreement), plus an applicable margin of 4.5%, in each case, subject to a quarter point reduction if total leverage
is less than 4.00 to 1.00. The Amendment also modifies the excess cash flow mandatory prepayment percentage, from a range of 0%
to 50% to a range of 0% to 75%, depending on the level of Aeroflex&rsquo;s senior secured leverage ratio, and extends through May
24, 2013 call protection provisions under the facility.</P>

fees and expenses in the aggregate amount of approximately $4 million, including a consent fee payable to each lender approving

Item 1.01.
Entry into a Material Definitive Agreement.
On May 24, 2012, Aeroflex Incorporated ("Borrower"),
a direct wholly-owned subsidiary of Aeroflex Holding Corp. ("Aeroflex"), entered into Amendment No. 1 (the "Amendment")
to the Credit and Guaranty Agreement, dated as of May 9, 2011, by and among Aeroflex, Borrower, certain subsidiaries of Borrower,
as guarantors thereto, the lenders party thereto and JPMorgan Chase Bank, N.A., as administrative agent (the "Credit Agreement").
The Amendment increases flexibility under
the total leverage ratio covenant. Pursuant to the Amendment, the maximum total leverage ratio (as defined in the Credit Agreement)
permitted as of June 30, 2012 will be 5.75 to 1.00, which periodically decreases to 3.50 to 1.00 on March 31, 2015. The Amendment
also increases the interest rate payable with respect to outstanding borrowings under the loan facility by 1.5% to either: (i)
the base rate (as defined in the Credit Agreement), plus an applicable margin of 3.5%, or (ii) the adjusted LIBOR rate (as defined

is less than 4.00 to 1.00. The Amendment also modifies the excess cash flow mandatory prepayment percentage, from a range of 0%
to 50% to a range of 0% to 75%, depending on the level of Aeroflex's senior secured leverage ratio, and extends through May
24, 2013 call protection provisions under the facility.
The Amendment will result in additional
interest expense of approximately $10 million per year. In addition, as a result of the Amendment, Aeroflex paid certain one-time
fees and expenses in the aggregate amount of approximately $4 million, including a consent fee payable to each lender approving
the Amendment.
