Commission on April 19, 2002 and amended and supplemented by Amendment No.
1 thereto dated April 22, 2002 and Amendment No. 2 thereto dated April 29,
2002, relates to the offer by Testco Acquisition Corp., a Delaware
corporation (the "Purchaser") and a wholly owned subsidiary of Aeroflex
Incorporated, a Delaware corporation ("Aeroflex"), to purchase all of the
outstanding shares of common stock, par value $.01 per share (including the
associated rights to purchase common stock, the "Shares") of IFR Systems,
Inc., a Delaware corporation (the "Company"), at a price of $1.35 per
Share, net to the seller in cash, upon the terms and subject to the

was inadvertently paid; the balance of $120 of the filing fee is being paid
