MURRAY FRANK LLP Investigates Breaches Of Fiduciary Duty Regarding Acquisition Of Integral Systems Inc. By Kratos Defense & Security Solutions Inc.

MURRAY FRANK LLP is investigating claims of breach of fiduciary duty by certain members of the board of directors of Integral Systems Inc. (NASDAQ: ISYS) ("Integral" or the "Company") in relation to the acquisition of Integral by Kratos Defense & Security Solutions Inc. ("Kratos").

On May 16, 2011, Integral and Kratos announced that Kratos will acquire Integral pursuant to a transaction under which Integral stockholders will receive $5.00 in cash and .588 of a share of Kratos common stock for each share of Integral common stock held. The deal should total an aggregate value of approximately $366 million or $13.00 per share. This amount represents a discount to Integral's closing price on May 13, 2011 of $13.00.

The investigation concerns whether certain members of the board of directors breached their fiduciary duty in connection with their efforts to sell Integral to Kratos at an inadequate price through an unfair process that significantly undervalues the Company.

If you are a current investor in Integral who purchased ISYS shares before May 16, 2011, and you wish to discuss this investigation or have any questions concerning this notice or your rights or interests with respect to these matters, please contact Katherine Smith at (800) 497-8076 or (212) 682-1818, or by email at [email protected].
