ZOLL Wins World Class Service Excellence Award

Tuesday, April 27, 2004 – CHELMSFORD, MASS.—ZOLL Medical Corporation (NASDAQ: ZOLL), a manufacturer of non-invasive cardiac resuscitation devices, announced today that it has won a NorthFace ScoreBoard Award, presented by the Omega Management Group Corporation. The annual award is presented to companies that demonstrate exemplary customer service and exceed customer expectations. The service categories in which ZOLL was recognized in 2003 were technical support, order shipment, and depot repair.

“While providing excellent customer service is a goal of every product or service company, maintaining it over time is not an everyday occurrence,” said Richard A. Packer, President and Chief Executive Officer of ZOLL. “I am proud of the ZOLL employees whose continued diligence has helped to earn this well-deserved honor. It shows our commitment to enhancing our customers’ ability to save lives through cardiac resuscitation.”

To qualify for the NorthFace ScoreBoard Award, a company must meet four criteria: 1) senior management commitment to exceeding customer expectations; 2) customer satisfaction program that identifies and corrects customer problems; 3) measuring the level of customer satisfaction with product/service; and 4) achieving an overall score of 4.0 out of 5.0 for a year. In ZOLL’s case, Omega conducted quarterly telephone surveys with 100 customers to determine level of achievement and quantify results. Highlights from the ZOLL customer satisfaction surveys were as follows:

· 98% of customers responding to the technical support survey rated ZOLL as meeting or exceeding their expectations.
· 97% of customers who responded to the order/delivery survey rated ZOLL as meeting or exceeding their expectations.
