CARDIAC SCIENCE REACHES LAWSUIT AGREEMENT

Cardiac Science, a manufacturer of automatic public-access defibrillators, has executed a memorandum of understanding with plaintiffs' class counsel to dismiss the class action lawsuit related to the company's proposed merger with Quinton Cardiology Systems that is pending in the Delaware Chancery Court.

Plaintiffs' class counsel has agreed to withdraw their motion for preliminary injunction and release all parties associated with the transaction regarding disclosure claims involving the merger. Counsel for an institutional shareholder in a related case has also entered into the same agreement. In addition, plaintiffs' class counsel in the Delaware class action has agreed to dismiss all remaining damage claims without prejudice.

In exchange for such agreements, Cardiac Science agreed to make additional disclosures in its registration statement on Form S-4 filed with the Securities and Exchange Commission in connection with the proposed merger transaction. A final settlement agreement is subject to approval by the Delaware Chancery Court.
