      ZOLL Medical Corporation Announces Record Annual Revenues
                    Reports Fourth Quarter Results

    CHELMSFORD, Mass.--(BUSINESS WIRE)--Nov. 11, 2004--ZOLL Medical
Corporation (NASDAQ: ZOLL), a manufacturer of resuscitation devices
and software solutions, today announced record annual revenues of
$211,785,000, an increase of 15% as compared to annual revenues of
$184,603,000 last year. Net income for the year decreased 30% to
$8,956,000 as compared to $12,850,000 in the prior year.
    Annual sales to the North American market grew by 23% to $170.5
million as compared to $138.5 million for the prior year. Sales to the
North American hospital market increased 39% to $88.1 million as
compared to $63.6 million last year. Sales to the North American
pre-hospital market increased 13% to $62.4 million, as compared to
$55.4 in the prior year. International revenues decreased by 10% to
$41.3 million as compared to $46.1 million last year. AED Plus(TM)
sales increased 61% to $30.4 million for the year, as compared to
$18.8 million in the prior year.
    Fourth quarter revenues of $55,728,000 also set a record,
reflecting 11% growth over the fourth quarter of 2003. Net income of
$2,145,000 or $0.23 per share decreased 56% as compared to the prior
year fourth quarter. These results were in line with guidance given
earlier this month.
    Fourth quarter sales to the North American market grew to $46.8
million, an increase of 19% as compared to the fourth quarter of 2003.
Sales to the North American hospital market increased 37% to $25.8
million as compared to the fourth quarter of last year. Sales to the
North American pre-hospital market increased 3% to $16.2 million as
compared to the same period last year. International sales decreased
by 17% to $9.0 million as compared to the fourth quarter last year.
AED Plus(TM) product sales increased by 68% to $8.8 million as
compared to $5.3 million in the prior year.
    Regarding the fourth quarter, as previously disclosed, the Company
had approximately $2.5 million of additional orders in the quarter
that it planned to ship but was unable to do so due to unexpected unit
configurations. Also, as previously discussed, a higher volume of low
parameter hospital business, resulting in lower overall prices,
reduced gross margins to 56% from 58% a year ago. Other income was
lower than the prior year reflecting foreign exchange rate
fluctuations. The tax rate was reduced to 30% for the year and 17% for
the quarter as fixed research and development credits and export tax
incentives were applied to lower than expected income before tax.
    Richard A. Packer, President and Chief Executive Officer of ZOLL,
commented, "We were disappointed with our fourth quarter results and
our overall year. We did not achieve the results we desired, in spite
of significant investments in both sales and marketing, and R&D. We
have yet to make these investments payoff. However, there were a
number of areas of the business that performed better than expected
during the year. We were particularly pleased with our continued
strong performance in the North American hospital market. Sales grew
in excess of 39% overall, and 18% with all military sales excluded. We
continue to standardize large U.S. hospitals on the M Series(TM)
product line due to its superior features and our proprietary biphasic
technology."
    "Sales of our AED Plus(TM) product were also outstanding", Mr.
Packer continued, "as shipments increased over 60% in both the
comparable prior year quarter and fiscal year. This result was
significantly better than our stated goal of 50%. It is clear that we
are continuing to take market share. The strength of our distribution
has grown throughout the year. We believe customers are increasing
their understanding of the benefits the AED Plus(TM) product
provides."
    Commenting further, Mr. Packer observed, "Throughout the year, and
again in the fourth quarter, our results in International have been
disappointing. We believe we have lost ground in Europe and have made
several management changes to address the situation. We expect
improved performance in 2005, particularly in the second half, as
these changes have their desired effect. Also, softness continues in
the U.S. EMS market due to state budget deficits. This tight market
has reduced our ability to gain market share in this important market.
However, we are cautiously optimistic that we will see an improvement
in spending in the second half of fiscal 2005 and that pent up demand
will provide an additional boost."
    "Moving beyond the core business, in 2004 we made significant
progress in our efforts to move the company beyond defibrillation, and
develop a broader resuscitation portfolio," Mr. Packer said. "We have
achieved good early results from our acquisition of the Infusion
Dynamics business. We look for acceleration of this business as we
obtain a CE Mark and take the Power Infuser(R) fluid resuscitation
product to militaries around the world. Even more significant, our
recent acquisition of Revivant adds a whole new growth dimension to
ZOLL. We believe technology related to improving CPR for victims in
cardiac arrest represents a market potential in line with the current
professional defibrillator market, which currently stands at over $650
million. We expect the AutoPulse(TM) product to lead the way in the
development of this market, and create selling synergies for ZOLL that
we have not experienced in the past."
    Looking forward, Mr. Packer noted, "As we absorb the Revivant
acquisition we anticipate some transition issues, particularly in
balancing selling efforts on AutoPulse(TM) with those on other
products. As stated earlier, we have made changes in International but
it will take some time to get back on track. As a result of these
issues, primarily having an impact on the first half of 2005, we
expect annual earnings for 2005 to be in the range of $1.35 to $1.55
per share. We continue to anticipate a sharp improvement in results as
we move to the second half of 2005 due to acceleration of the
AutoPulse(TM) and improvement of International performance. While we
also expect the U.S. EMS market to improve in the second half, we are
not yet anticipating the full impact of a recovery in our guidance."
    Mr. Packer concluded, "The long term growth and profitability
prospects for ZOLL have never been better. We have a proven business
model that is profitable and can support high growth. Our balance
sheet is strong and we continue to generate cash from operations. Our
business can be unpredictable at times but it is built on solid
fundamentals and will perform over the longer term. Investments made
in 2004 that have hurt our bottom line this year should provide a
boost in 2005. I have not been this enthusiastic about the ZOLL
product pipeline and the position of our distribution since we
introduced our rectilinear biphasic technology on the heels of the M
Series(TM) launch. We expect to build significant momentum in 2005 and
are prepared for continued growth in 2006 and beyond."
