April 23, 2008 - Shareholder Rights Plan Renewed INVESTOR CONTACT: A. Ernest WhitonChief Financial OfficerZOLL Medical Corporation+1 (978) 421-9655 ZOLL Medical Corporation Renews Shareholder Rights Plan April 23, 2008—CHELMSFORD, Mass. — ZOLL Medical Corporation (NASDAQGS: ZOLL), a manufacturer of resuscitation devices and software solutions, announced today that its Board of Directors has renewed its Shareholder Rights Plan, which was originally adopted by ZOLL’s Board of Directors in June 1998. Richard A. Packer, President and Chief Executive Officer of ZOLL, stated, “The Board believes that a Shareholders Rights Plan continues to enhance its ability to protect shareholder interests and ensures that shareholders receive fair treatment in the event of any coercive takeover attempt. The Plan is intended to provide the Board with sufficient time to consider any and all alternatives to such an action. The Board believes it is protecting the interests of all of its shareholders.” In connection with the renewal of the Shareholder Rights Plan, the Board of Directors declared a dividend distribution of one preferred stock purchase right for each outstanding share of ZOLL Medical Corporation’s common stock to shareholders of record as of the close of business on April 24, 2008. Initially, these rights will not be exercisable and will trade with the shares of ZOLL Medical Corporation’s common stock. Under the Shareholder Rights Plan, the rights generally will become exercisable if a person becomes an “acquiring person” by acquiring 15% or more of the common stock of ZOLL Medical Corporation or if a person commences a tender offer that could result in that person owning 15% or more of the common stock of ZOLL Medical Corporation. If a person becomes an “acquiring person,” each holder of a right (other than the acquiring person) would be entitled to purchase, at the then-current exercise price, such number of shares of preferred stock which are equivalent to shares of ZOLL Medical Corporation’s common stock having a value of twice the exercise price of the right. If ZOLL Medical Corporation is acquired in a merger or other business combination transaction after any such event, each holder of a right would then be entitled to purchase, at the then-current exercise price, shares of the acquiring company’s common stock having a value of twice the exercise price of the right.
