Cardiac Science Shareholder Investigation by Briscoe Law Firm Concerning the Merger with Opto Circuits (India) Limited

The Briscoe Law Firm, PLLC, founded by a former state prosecutor and enforcement attorney for the United States Securities and Exchange Commission, and the law firm of Powers Taylor, LLP are investigating potential legal claims against the Board of Directors of Cardiac Science Corporation (“Cardiac Science” or “CSCX”) (NASDAQ: CSCX) related to the proposed acquisition of Cardiac Science by Opto Circuits (India) Limited.

The definitive merger agreement, which was announced on October 19, 2010, involves a transaction valued at approximately $55 million under which Cardiac Science shareholders will receive only $2.30 in cash for each share of Cardiac Science/CSCX common stock they hold. The transaction is structured to include an all-cash tender offer by a wholly owned subsidiary of Opto Circuits, followed by a second-step merger of the companies, to be completed in the fourth quarter of 2010.

At least one analyst has set a target price for Cardiac Stock at $6.00 per share, and Cardiac Stock traded as high as $2.48 per share in August 2010. Based on the lack of a premium to shareholders and other factors, the proposed transaction may undervalue Cardiac Science/CSCX shares and not be fair to Cardiac Science shareholders. The investigation relates to possible breaches of fiduciary duty and other violations of state law by the Board of Directors of Cardiac Science for approving this transaction and whether Cardiac Science’s Board of Directors acted in the shareholders’ best interests.
