CMD Cantel Medical Corp

Opto Circuits (India) Limited (�Opto Circuits�) today announced that it has completed its acquisition of Criticare Systems, Inc. (�Criticare�) (AMEX:CMD). Through a tender offer by its wholly-owned subsidiary, Packer Acquisition Corporation (the �Purchaser�), Opto Circuits had previously acquired approximately 92.8% of the outstanding shares of Criticare common stock for a purchase price of $5.50 per share in cash and without interest. As the final step of the acquisition, Opto Circuits caused the Purchaser to merge with and into Criticare effective April 10, 2008. In the merger, each Criticare share not purchased in the tender offer, other than shares for which statutory appraisal rights are properly exercised, was converted into the right to receive the same $5.50 per share in cash and without interest, as received by Criticare stockholders in the tender offer. As a result, Criticare is now a wholly-owned subsidiary of Opto Circuits.
