NEW YORK, NY, May 25, 2006 – As previously reported, L-3 Communications (NYSE: LLL) and OSI Systems, Inc. (OSI) are parties to a litigation arising out of a letter of intent between the company and OSI relating to the company’s acquisition of the detection systems business of PerkinElmer, Inc. OSI brought counterclaims against the company alleging that the company defrauded OSI and breached fiduciary duties alleged to be owed to OSI. On May 24, 2006, the jury found in favor of OSI and awarded $125.6 million of damages, including awards of $33 million for compensatory damages and $92.6 million for punitive damages. The company believes this verdict and the damages awarded are inconsistent with the law and evidence presented. The company intends to move to have the verdict set aside and, if necessary, to appeal.
