                            ZOLL MEDICAL CORPORATION
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.   Basis of Presentation
     The Consolidated Balance Sheet as of March 30, 2003, the Consolidated
     Income Statements for the three and six months ended March 30, 2003 and
     March 31, 2002, and the Consolidated Statements of Cash Flows for the six
     months ended March 30, 2003 and March 31, 2002 are unaudited, but in the
     opinion of management include all adjustments, consisting of normal
     recurring items, necessary for a fair presentation of results for these
     interim periods. Preparing financial statements requires management to make
     estimates and assumptions that affect the reported amounts of assets,
     liabilities, revenues and expenses. Examples include provisions for
     returns, bad debts and the estimated lives of fixed assets. Actual results
     may differ from these estimates. The results for the interim periods are
     not necessarily indicative of results to be expected for the entire year.
     The information contained in the interim financial statements should be
     read in conjunction with the Company's audited financial statements as of
     and for the year ended September 29, 2002 included in its Form 10-K filed
     with the Securities and Exchange Commission ("SEC") on December 30, 2002.
     Certain reclassifications may have been made to the prior years' unaudited
     consolidated financial statements to conform to the current period
     presentation with no impact on net income.

2.   Segment and Geographic Information
     Segment information: The Company operates in a single business segment: the
     design, manufacture and marketing of an integrated line of proprietary
     non-invasive cardiac resuscitation devices, and systems used for emergency
     resuscitation of cardiac arrest victims. In order to make operating and
     strategic decisions, ZOLL's chief operating decision maker evaluates
     revenue performance based on the worldwide revenues of four
     customer/product categories but, due to shared infrastructures,
     profitability based on an enterprise-wide measure. These customer/product
     categories consist of (1) the sale of cardiac resuscitation devices and
     accessories to the North American hospital market, (2) the sale of the same
     items and data collection management software to the North American
     pre-hospital market, (3) the sale of disposable/other products in North
     America, (4) the sale of cardiac resuscitation devices, accessories and
     disposable electrodes to the international market.

     Net sales by customer/product categories were as follows:

3.  Comprehensive Income
    The Company computes comprehensive income in accordance with Statement of
    Financial Accounting Standards No. 130 "Reporting Comprehensive Income"
    (SFAS 130). SFAS 130 establishes standards for the reporting and display of
    comprehensive income and its components in the financial statements. Other
    comprehensive income, as defined, includes all changes in equity during a
    period from non-owner sources, such as unrealized gains and losses on
    available-for-sale securities and foreign currency translation. Total
    comprehensive income for the three months and six months ended March 30,
    2003 and March 31, 2002 were as follows:

4.  Stock Option Plans
    At March 30, 2003, the Company had three stock-based compensation plans. The
    Company's 1992 and 2001 stock option plans provide for the granting of
    options to officers and other key employees to purchase the Company's Common
    Stock at a purchase price, in the case of incentive stock options, at least
    equal to the fair market value per share of the outstanding Common Stock of
    the Company at the time the option is granted, as determined by the
    Compensation Committee of the Board of Directors. Options are no longer
    granted under the 1992 plan. The options become exercisable ratably over two
    or four years and have a maximum life of 10 years. The Company's
    Non-employee Director Stock Option Plan provides for the grant of options to
    purchase 10,000 shares of Common Stock to Directors of the Company who are
    not also employees of the Company or any of its subsidiaries upon the
    Directors' initial appointment to the Board of Directors. The Non-employee
    Director options vest in equal annual installments over a four year period.
    The Non-employee Director options are granted at an exercise price equal to
    the fair market value of the Common Stock on the date the option is granted.

    In December 2002, the Financial Accounting Standards Board (FASB) issued
    Statement of Financial Accounting Standard (SFAS) No. 148, "ACCOUNTING FOR
    STOCK-BASED COMPENSATION - TRANSITION AND DISCLOSURE - AN AMENDMENT OF SFAS
    NO. 123", which provides optional transition guidance for those companies
    electing to voluntarily adopt the accounting provisions of SFAS No. 123. In
    addition, SFAS No. 148 amends the disclosure requirements of SFAS No. 123 to
    require prominent disclosures in both annual and interim financial
    statements about the method of accounting for stock-based employee
    compensation and the effect of the method used on reported results. The
    Company accounts for the plans under the recognition and measurement
    provisions of Accounting Principles Board No. 25, "ACCOUNTING FOR STOCK
    ISSUED TO EMPLOYEES," and related Interpretations. No stock-based employee
    compensation cost is reflected in net income, as all options granted under
    those plans had an exercise price equal to the market value of the
    underlying common stock on the grant date. The following table illustrates
    the effect on net income and earnings per share if the Company had applied
    the fair value recognition provisions of Statement of Financial Accounting
    Standards No. 123, "ACCOUNTING FOR STOCK-BASED COMPENSATION", to the
    stock-based employee compensation. The estimated fair value of each option
    is calculated using the Black-Scholes option-pricing model:

6. Derivative Instruments and Hedging Activities:
The Company recognizes all derivative financial instruments in the consolidated
financial statements at fair value, regardless of the purpose or intent for
holding the instrument, in accordance with FASB Statement No. 133, ACCOUNTING
FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. Changes in the fair value of
derivative instruments are recorded in earnings unless hedge accounting criteria
are met. For derivative instruments designated as fair value hedges, the changes
in fair value of both the derivative instrument and the hedged item are recorded
in earnings under investment and other income. The Company does not enter into
any derivative transaction for speculative purposes.

The Company has international offices in Canada, United Kingdom, Netherlands,
France, Germany, and Australia. These subsidiaries transact business in their
functional or local currency. Therefore, we are exposed to foreign currency
exchange risks and fluctuations in foreign currencies, along with economic and
political instability in the foreign countries in which we operate, all of which
could adversely impact our results of operations and financial condition.

The Company uses forward contracts to reduce our exposure to foreign currency
risk due to fluctuations in exchange rates underlying the value of intercompany
accounts receivable denominated in foreign currencies. A forward contract
obligates us to exchange predetermined amounts of specified foreign currencies
at specified exchange rates on specified dates. These forward contracts are
denominated in the same currency in which the underlying foreign currency
receivables are denominated and bear a contract value and maturity date that
approximate the value and expected settlement date, respectively, of the
underlying transactions.

The Company had a forward exchange contract outstanding in the notional amount
of approximately $4.3 million at March 30, 2003, and zero at March 31, 2002.
This contract serves as a hedge of a substantial portion of our Euro-denominated
intercompany balances and matures in three months. The fair value of this
foreign currency derivative contract outstanding at March 30, 2003 and March 31,
2002 was approximately $4.3 million and zero, respectively. Net foreign exchange
gains recorded to date on this forward exchange contract totaled approximately

In December 2002, the FASB issued Interpretation No. 45, "GUARANTOR'S ACCOUNTING
AND DISCLOSURE REQUIREMENTS", which requires the disclosure of any guarantees in
place prior to December 31, 2002 and the recognition of a liability for the fair
value of any guaranteed entered into or modified after that date. The Company is
not a guarantor in arrangements that require the recognition of a liability or
disclosure under Interpretation No. 46, therefore does not believe it will
materially impact the Company's consolidated financial statements.

In January 2003, the FASB issued Interpretation No. 46, "CONSOLIDATION OF
VARIABLE INTEREST ENTITIES", to clarify the conditions under which the assets,
liabilities and activities of another entity should be consolidated into the
financial statements of a company. Interpretation No. 46 requires the
consolidation of a variable interest entity by a company that bears the majority
of the risk of loss from the variable interest entity's activities or is
entitled to receive the majority of the variable interest entity's residual
returns. The provisions of Interpretation No. 46 are required to be adopted by
the Company in Q4 of fiscal 2003. The Company currently has minor equity
investments in LifeCor, Inc., ResQSystems, Inc., and AED@Home with a carrying
value of approximately $5.0 million. The Company is in the process of


                                       8

determining the effect of adoption of Interpretation No. 46, but does not
believe it will materially impact the Company's consolidated financial
results of operations.

In April 2003, the FASB issued SFAS No. 149, "AMENDMENT OF STATEMENT 133 ON
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES", which is effective for contracts
entered into or modified after June 30, 2003 and for hedging relationships
designated after June 30, 2003. SFAS No. 149 amends and clarifies the accounting
for derivative instruments and hedging activities under SFAS No. 133 "ACCOUNTING
FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES", as amended by SFAS No. 137
and SFAS No. 138. The Company is in the process of determining the effect of
adoption of SFAS No. 149, but does not believe it will materially impact the
Company's consolidated financial statements.


ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

THREE MONTHS ENDED MARCH 30, 2003 COMPARED TO THREE MONTHS ENDED MARCH 31, 2002

Net sales increased 34% to $46.6 million for the three months ended March 30,
2003 as compared to $34.7 million for the same period a year earlier. Sales to
the North American hospital market amounted to $18.1 million, a 57% increase in
comparison to $11.5 million for the same period a year prior. Sales to the North
American pre-hospital market increased 18% to $13.1 million, up from $11.1
million in the previous year. Total North American sales increased 31% to $36.2
million in comparison to $27.7 million for the same period a year earlier. The
increase in sales over the prior quarter in 2002 can be attributed to shipments
to the United States military and increased market share gains with our AED Plus
product. International sales increased 49% to $10.4 million in comparison to
$7.0 million for the same period a year earlier. International direct sales
operations continue to perform well as compared to the prior year period,
particularly in the United Kingdom and Australia which approximately doubled
their sales. Distributor operations also exceeded the prior year, with
particularly strong growth in China.

Gross margin for the three months ended March 30, 2003 decreased to 54.6% as
compared to 55.6% for the comparable prior year quarter. The lower margin from
the prior comparable period is due to an increasing percentage of international
shipments and increased shipments to the United States military. International
shipments, including sales to distributors, typically carry lower gross margins
than sales in North America, while we increased shipments to the United States
military which reflect volume pricing.

Selling and marketing expenses remained consistent as a percentage of net sales
at 32.6%. Selling and marketing expenses in total increased $3.8 million or 34%
for the three months ended March 30, 2003 compared to the three months ended
March 31, 2002. The increase in selling and marketing expense reflects our
continued investment in our international operations, expansion of our AED Plus
sales force, and higher marketing costs related to increased promotional
activities.

General and administrative expenses decreased as a percentage of net sales to
6.9% from 7.2%. General and administrative expenses increased $702,000 or 28%
for the three months ended March 30, 2003 compared to the three months ended
March 31, 2002. This increase was due to staffing and related personnel costs,
professional fees and increased insurance premiums.

Research and development expenses decreased as a percentage of net sales to 7.8%
from 8.5%. Research and development expenses increased $686,000 or 23% for the
three months ended March 30, 2003 compared to the three months ended March 31,
2002. This change reflects additional personnel we have hired to support ongoing
future product development.

Our effective tax rate decreased from 34% to 33% for the three months ended
March 30, 2003 as compared to the same period in fiscal 2002, reflecting
increased use of research and development credits stemming from the development
of our CCT and AED Plus products.

SIX MONTHS ENDED MARCH 30, 2003 COMPARED TO SIX MONTHS ENDED MARCH 31, 2002

Our net sales increased 32% to $89.7 million for the six months ended March 30,
2003 as compared to $68.1 million for the same period a year earlier. Sales to
the North American hospital market amounted to $31.1 million, a 31% increase in
comparison to $23.8 million for the same period a year prior. Sales to the North
American pre-hospital market increased 21% to $24.5 million, up from $20.3
million in the previous year. Total North American sales increased 22% to $65.3
million in comparison to $53.7 million for the same period a year earlier. The
increase in North American sales over the prior comparable period reflected
increased defibrillator sales, particularly the shipments to the United States
military; the addition of our AED Plus product; and stronger software sales to


                                       9

<PAGE>

EMS customers. International sales increased 69% to $24.3 million in comparison
to $14.4 million for the same period a year earlier. International sales
reflected strength from both our direct and distributor operations. Our direct
subsidiaries in the United Kingdom, Germany and Australia have grown very well,
more than doubling sales for the same period in the prior year. Our distributor
operations have also performed well, particularly in Europe.

Gross margin for the six months ended March 30, 2003 was 54.1% compared to 56.1%
for the comparable prior period. The lower margin was driven by a shift in our
geographic mix, as our International sales (which generally have lower margins
as described above) growth outpaced North American sales growth during the
period. International shipments during the six months ended March 30, 2003 have
increased approximately 69% from the prior year and accounted for 27% of our
consolidated sales. In addition, increased shipments to the United States
military reduced margins as these shipments reflect volume pricing.

Selling and marketing expenses remained relatively constant as a percentage of
net sales at 33%. Selling and marketing expenses increased $7.0 million or 31%
for the six months ended March 30, 2003 compared to the six months ended March
31, 2002. This increase reflects expansion of our international sales force,
worldwide public access defibrillation distribution expansion, increases to the
North America sales management team, new North America training resources and
normal additions to our North America direct sales force. Also contributing to
the increase were additional resources dedicated to our global marketing effort
for our AED Plus product.

General and administrative expenses decreased as a percentage of net sales to
6.9% from 7.4%. General and administrative expenses increased $1.2 million or
24% for the six months ended March 30, 2003 compared to the six months ended
March 31, 2002. The increase from the comparable prior period primarily reflects
additional personnel and related costs to support our growth, increased employer
contributions to our defined contribution 401k Plan, higher insurance premiums,
and legal fees associated with settlement of a patent infringement suit.

Research and development expenses decreased as a percentage of net sales to 7.5%
from 8.3%. Research and development expenses increased $1.1 million or 19% for
the six months ended March 30, 2003 compared to the six months ended March 31,
2002. This change reflects additional personnel we have hired to support ongoing
future product development.

Our effective tax rate decreased from 34% to 33% for the six months ended March
30, 2003 as compared to the same period in fiscal 2002, reflecting increased
research and development credits stemming from the development of our CCT and
AED Plus products.


LIQUIDITY AND CAPITAL RESOURCES

Our total cash, cash equivalents and marketable securities decreased $282,000
for the six months ended March 30, 2003. Our cash and cash equivalents at March
30, 2003 totaled $55.0 million compared with $55.7 million at September 29,
2002. In addition, we had marketable securities amounting to $10.5 million at
March 30, 2003 in comparison to $10.1 million at September 29, 2002.

Cash provided by operating activities for the six months ended March 30, 2003
was $4.7 million as compared to $9.6 million during the same period in fiscal
year 2002. This decrease was primarily attributable to increases in accounts
receivable, inventory, and early payment of vendor invoices in order to take
advantage of early payment discount opportunities, offset by improved net
earnings, stock option tax benefits, and increased depreciation expense.
Accounts receivable increased as a result of higher revenues however, our days
of sales outstanding remained consistent. Inventory has increased as we prepare
for higher sales volumes of our M-Series and AED Plus products.

Cash used for investing activities amounted to $6.5 million during the six
months ended March 30, 2003 compared to $8.2 million during the six months ended
March 31, 2002. This change reflects equity investments totaling approximately
$3.0 million in Lifecor, Inc., ResQSystems, Inc., and AED@Home, which were
offset by fewer fixed asset additions and an increased number of sales of
marketable securities than in the same period a year ago.

Cash provided by financing activities was $1.0 million for the six months ended
March 30, 2003 compared to $330,000 for the same period in fiscal year 2002
reflecting increased stock option activity.

                                       10
<PAGE>

We maintain a working capital line of credit with our bank. Under this working
capital line, we may borrow on a demand basis. Currently, we may borrow up to
$12.0 million at an interest rate equal to the bank's base rate. No borrowings
were outstanding on this line at the end of the second quarter of fiscal 2003.

Our only contractual obligations consist of operating lease commitments. Our
total lease commitments are approximately $9.5 million, of which $1.2 million is
due in less than one year, $4.8 million is due in one to four years, and $3.5
million is due in five to eight years. In March 2003, we executed a long-term
lease on a new facility in Chelmsford, Massachusetts, which is effective
beginning in July 2003.

We believe that the cash generated by operations and amounts available under our
existing line of credit will be sufficient to meet our ongoing operating and
capital expenditure requirements for at least the remainder of the fiscal year.

LEGAL AND REGULATORY AFFAIRS

We are involved in the normal course of our business in various litigation
matters and regulatory issues, including product recalls. Although we are unable
to determine at the present time the exact amount of any impact in any pending
matters, we believe that none of the pending matters will have an outcome
material to our financial condition or business.

CRITICAL ACCOUNTING POLICIES

Our most critical accounting policies include revenue recognition and those that
are reflective of significant judgments and uncertainties, and may potentially
result in materially different results under different assumptions and
conditions. We believe that our most critical accounting policies are limited to
those described below. For a detailed discussion on the application of these and
other accounting policies, see Note A in the notes to the fiscal 2002
consolidated financial statements, included in our Form 10-K filed with the SEC
on December 30, 2002.

REVENUE RECOGNITION

Revenues from sales of cardiac resuscitation devices, disposable electrodes and
accessories are recognized when a signed non-cancelable purchase order exists,
the product is shipped, title and risk of loss have passed to the customer, the
fee is fixed and determinable, and collection is considered probable. Revenues
are recorded net of estimated returns.

We also license software under non-cancelable license agreements and provide
services including training, installation, consulting and maintenance, which
consist of product support services, periodic updates and unspecified upgrade
rights (collectively, post-contract customer support ("PCS")). Revenue from the
sale of software is recognized in accordance with the American Institute of
Certified Public Accountants ("AICPA") Statement of Position ("SOP") 97-2,
"Software Revenue Recognition," as amended. License fee revenues are recognized
when a non-cancelable license agreement has been signed, the software product
has been shipped, there are no uncertainties surrounding product acceptance, the
fees are fixed and determinable, and collection is considered probable. Revenues
from maintenance agreements and upgrade rights are recognized ratably over the
period of service.

Our software arrangements contain multiple elements, which include software
products, services and PCS. In general, we do not have vendor specific objective
evidence of fair value for our software products. Accordingly, for transactions
where vendor specific objective evidence exists for undelivered elements but not
for delivered elements, we use the residual method as discussed in SOP 98-9,
"Modification of SOP 97-2, With Respect to Certain Transactions." Under the
residual method, the total fair value of the undelivered elements, as indicated
by vendor specific objective evidence, is deferred and the difference between
the total arrangement fee and the amount deferred for the undelivered elements
is recognized as revenue related to the delivered elements.

ALLOWANCE FOR DOUBTFUL ACCOUNTS / SALES RETURNS AND ALLOWANCES

We maintain an allowance for doubtful accounts for estimated losses, which are
included in bad debt expense, resulting from the inability of our customers to
make required payments. We determine the adequacy of this allowance by regularly
reviewing the aging of our accounts receivable and evaluating individual
customer receivables, considering customers' financial condition, credit history
and current economic condition. We also maintain an estimate of potential future
product returns and discounts given related to trade-ins and to current period
product receivables. We analyze the rate of historical returns when evaluating
the adequacy of the allowance for sales returns, which are included with the
allowance for doubtful accounts on our balance sheet.

                                       11
<PAGE>

As of March 30, 2003 our accounts receivable balance of $43.8 million is
reported net of allowances for doubtful accounts of $3.7 million. We believe our
reported allowances at March 30, 2003 are adequate. If the financial conditions
of our customers were to deteriorate, resulting in their inability to make
payments, we may need to record additional allowances, resulting in additional
expenses being recorded for the period in which such determination was made.

WARRANTY RESERVES

Our products are sold with warranty provisions that require us to remedy
deficiencies in quality or performance over a specified period of time, usually
one to five years. We provide for the estimated cost of product warranties at
the time revenue is recognized. While we engage in product quality programs and
processes, our warranty obligation is affected by product failure rates,
material usage and service delivery costs incurred in correcting a product
failure. We believe that our recorded liability of $2.6 million at March 30,
2003 is adequate to cover future costs for the servicing of our products sold
through that date. If actual product failure rates, material usage or service
delivery costs differ from our estimates, revisions to the estimated warranty
liability would be required.

INVENTORY RESERVES

Significant management judgment is required to determine the reserve for
obsolete or excess inventory. Inventory on hand may exceed future demand either
because the product is outdated, obsolete, or because the amount on hand is in
excess of future needs. We provide for the total value of inventories that we
determine to be obsolete based on criteria such as customer demand and changing
technologies. At March 30, 2003, our inventory reserves were $2.4 million, or
6.7% of our $35.9 million gross inventories.

We value our inventories at the lower of cost or market. Cost is determined by
the first-in, first-out ("FIFO") method, including material, labor and factory
overhead.

SAFE HARBOR STATEMENTS

Except for the historical information contained herein, the matters set forth
herein are forward looking statements within the meaning of Section 27A of the
Securities Act of 1933 as amended, and Section 21E of the Securities Exchange
Act of 1934, as amended, that are subject to certain risks and uncertainties
that could cause actual results to differ materially from those set forth in the
forward looking statements. Such risks and uncertainties include, but are not
limited to: product demand and market acceptance risks, the effect of economic
conditions, results of pending or future litigation, the impact of competitive
products and pricing, product development and commercialization, technological
difficulties, the government regulatory environment and actions, trade
environment, capacity and supply constraints or difficulties, the results of
financing efforts, actual purchases under agreements, potential warranty issues,
the effect of the Company's accounting policies, and those items set forth in
the following section entitled "Risk Factors."

RISK FACTORS

  IF WE FAIL TO COMPETE SUCCESSFULLY IN THE FUTURE AGAINST EXISTING OR
  POTENTIAL COMPETITORS, OUR OPERATING RESULTS MAY BE ADVERSELY AFFECTED

    Our principal global competitors with respect to our entire cardiac
    resuscitation equipment product line are Physio-Control Corporation and
    Royal Philips Electronics. Physio-Control is a subsidiary of Medtronic,
    Inc., a leading medical technology company and Agilent Technologies'
    Healthcare Solutions Group is now part of the Medical Systems division of
    Royal Philips Electronics. Physio-Control has been the market leader in the
    defibrillator industry for over twenty years. As a result of
    Physio-Control's dominant position in this industry, many potential
    customers have relationships with Physio-Control that could make it
    difficult for us to continue to penetrate the markets for our products. In
    addition, Physio-Control, its parent and Royal Philips Electronics and other
    competitors each have significantly greater resources than we do.
    Accordingly, Physio-Control, Royal Philips Electronics and other competitors
    could substantially increase the resources they devote to the development
    and marketing of products that are competitive with ours. These and other
    competitors may develop and successfully commercialize medical devices that
    directly or indirectly accomplish what our products are designed to
    accomplish in a superior and/or less expensive manner. For example, we
    expect our competitors to develop and sell devices in the future that will
    compete directly with our M Series product line and although our biphasic
    waveform technology is unique, our competitors have devised alternative
    biphasic waveform technology. We have also licensed our biphasic waveform
    technology to GE Medical Systems Information Technologies.


                                       12
<PAGE>

    There are a number of smaller competitors in the United States, which
    include MRL and Cardiac Science, Inc. It is possible the market may embrace
    these competitors' products which could negatively impact our market share.

    In addition to external defibrillation and external pacing with cardiac
    resuscitation equipment, it is possible that other alternative therapeutic
    approaches to the treatment of sudden cardiac arrest may be developed. These
    alternative therapies or approaches, including pharmaceutical or other
    alternatives, could prove to be superior to our products.

    There is significant competition in the business of developing and marketing
    software for data collection, billing and data management in the emergency
    medical system market. Our principal competitors in this business include
    Healthware Technologies, Inc., Tritech Software Systems, Inc., Sweet
    Computer Services, Inc., RAM Software Systems, Inc., Intergraph Corporation
    and AmbPac, Inc., some of which have greater financial, technical, research
    and development and marketing resources than we do. Because the barriers to
    entry in this business are relatively low, additional competitors may easily
    enter this market in the future. It is possible that systems developed by
    competitors could be superior to our data management system. Consequently,
    our ability to sell our data management system could be materially impacted
    and our financial results could be materially and adversely affected.

  OUR OPERATING RESULTS ARE LIKELY TO FLUCTUATE WHICH COULD CAUSE OUR STOCK
  PRICE TO BE VOLATILE, AND THE ANTICIPATION OF A VOLATILE STOCK PRICE CAN
  CAUSE GREATER VOLATILITY

    Our quarterly and annual operating results have fluctuated and may continue
    to fluctuate. Various factors have and may continue to affect our operating
    results, including:

    -   high demand for our products which could disrupt our normal factory
        utilization and cause shipments to occur in uneven patterns;

    -   variations in product orders;

    -   timing of new product introductions;

    -   temporary disruptions on buying behavior due to changes in technology
        (e.g. shift to biphasic technology);

    -   changes in distribution channels;

    -   actions taken by our competitors such as the introduction of new
        products or the offering of sales incentives;

    -   the ability of our sales forces to effectively market our products;

    -   supply interruptions from our single source vendors;

    -   temporary manufacturing disruptions;

    -   regulatory actions, including actions taken by the FDA or similar
        agencies; and

    -   delays in obtaining domestic or foreign regulatory approvals.

    A large percentage of our sales are made toward the end of each quarter. As
    a consequence, our quarterly financial results are often dependent on the
    receipt of large customer orders in the last weeks of a quarter. The absence
    of these large orders could cause us to fall short of our quarterly sales
    targets, which in turn could cause our stock price to decline sharply. As we
    grow in size, and these large orders are received closer to the end of a
    period, we may not be able to manufacture, test, and ship all orders in time
    to count as revenue for that quarter.

    Based on these factors, period-to-period comparisons should not be relied
    upon as indications of future performance. In anticipation of less
    successful quarterly results, parties may take short positions in our stock.
    The actions of parties shorting our stock might cause even more volatility
    in our stock price. The volatility of our stock may cause the value of a
    stockholder's investment to decline rapidly.

  THE COMPANY'S LEASE IN BURLINGTON, MASS. EXPIRES IN JULY 2003, AND WE WILL
  RELOCATE ALL OF THE OPERATIONS CURRENTLY CONDUCTED IN BURLINGTON TO A NEW
  LOCATION IN CHELMSFORD, MASS. WHICH MAY CAUSE A DISRUPTION.

    The Company's lease at its Burlington, Mass. facility expires in July 2003.
    This facility houses our corporate headquarters, Sales and Marketing, and
    R&D departments, and manufacturing and distribution for our capital
    equipment line of business. We have executed a long-term lease on a new
    facility in Chelmsford, Mass. We plan to relocate our operations in July
    2003. We have been planning this move for a long time and do not believe it
    is likely to cause a material disruption to our business.

  THE CURRENT SEVERE ACUTE RESPIRATORY SYNDROME (SARS) MAY AFFECT OUR ABILITY
  TO APPROACH CUSTOMERS AND SELL OUR EQUIPMENT INTO AREAS WHERE THE ILLNESS IS
  MOST CONCENTRATED.

    Our sales personnel have seen restricted access to hospitals in Toronto and
    Hong Kong. If the current SARS illness spreads into significant parts of
    Europe and the United States we may experience difficulties in approaching,
    demonstrating, and selling our products to health facilities where the
    illness is most severe.

  THE AED PAD (PUBLIC ACCESS DEFIBRILLATION) BUSINESS IS NEW TO US. IF WE ARE
  NOT SUCCESSFUL IN ENTERING THIS BUSINESS SEGMENT, OUR OPERATING RESULTS MAY
  BE AFFECTED.

    The PAD market is a new market for us and has many new dynamics. This market
    involves many new types of non-traditional healthcare distributors, and the
    efficiency of these distributors may not be as robust as we expect. Payment
    from these distributors for products they purchase from us may be
    questionable if these distributors are unable to sell the product on to end
    users. These new types of distributors may present credit risks since they
    may not be well established and may not have the necessary business volumes.
    In addition, we may not be successful in gaining market acceptance of our
    AED Plus into alternative PAD markets if our PAD Distributors are not
    successful. Also, our focus upon the PAD market may distract our operations
    from our core M Series business. All of these items could cause our
    operating results to be unfavorably impacted.

    We have noticed that as the PAD market has grown, there have been an
    increasing number of smaller, start-up companies entering the market. In
    order to gain market share, these companies compete mainly on price. If
    these companies are able to capture a larger market share with lower prices,
    this may cause declining prices and negatively affect our operating results.

    Two of our major competitors have announced plans to enter the home market.
    We have also announced such a plan and if our plan turns out to be less
    effective or efficient, we might have difficulty building market share.

  WE MAY BE REQUIRED TO IMPLEMENT A COSTLY PRODUCT RECALL

    In the event that any of our products proves to be defective, we can
    voluntarily recall, or the FDA could require us to redesign or implement a
    recall of, any of our products. Both our competitors and we have, on
    numerous occasions, voluntarily recalled products in the past, and based on
    this experience, we believe that future recalls could result in significant
    costs to us and significant adverse publicity, which could harm our ability
    to market our products in the future. Though it is not possible to quantify
    the economic impact of a recall, it could have a material adverse effect on
    our business, financial condition and results of operations. For example, on
    December 15, 2002, we initiated a recall of approximately 5,000 AED Plus
    units to correct a potential fault that can occur during its operation. We
    are currently supplying to our customers new software which, when installed,
    eliminates the potential for this fault to occur. The cost of implementing
    this corrective action is currently estimated to be less than $200,000.

 CHANGES IN THE HEALTH CARE INDUSTRY MAY REQUIRE US TO DECREASE THE SELLING
 PRICE FOR OUR PRODUCTS OR COULD RESULT IN A REDUCTION IN THE SIZE OF THE
 MARKET FOR OUR PRODUCTS, EACH OF WHICH COULD HAVE A NEGATIVE IMPACT ON OUR
 FINANCIAL PERFORMANCE

    Trends toward managed care, health care cost containment, and other changes
    in government and private sector initiatives in the United States and other
    countries in which we do business are placing increased emphasis on the
    delivery of more cost-effective medical therapies which could adversely
    affect the sale and/or the prices of our products. For example:


                                       14
<PAGE>

    -   major third-party payers of hospital and pre-hospital services,
        including Medicare, Medicaid and private health care insurers, have
        substantially revised their payment methodologies during the last few
        years which has resulted in stricter standards for reimbursement of
        hospital and pre-hospital charges for certain medical procedures;

    -   Medicare, Medicaid and private health care insurer cutbacks could create
        downward price pressure in the cardiac resuscitation pre-hospital
        market;

    -   numerous legislative proposals have been considered that would result in
        major reforms in the U.S. health care system that could have an adverse
        effect on our business;

    -   there has been a consolidation among health care facilities and
        purchasers of medical devices in the United States who prefer to limit
        the number of suppliers from whom they purchase medical products, and
        these entities may decide to stop purchasing our products or demand
        discounts on our prices;

    -   there is economic pressure to contain health care costs in international
        markets;

    -   there are proposed and existing laws and regulations in domestic and
        international markets regulating pricing and profitability of companies
        in the health care industry; and

    -   there have been initiatives by third party payers to challenge the
        prices charged for medical products which could affect our ability to
        sell products on a competitive basis.

    Both the pressure to reduce prices for our products in response to these
    trends and the decrease in the size of the market as a result of these
    trends could adversely affect our levels of revenues and profitability of
    sales, which could have a material adverse effect on our business.

  GENERAL ECONOMIC CONDITIONS MAY CAUSE OUR CUSTOMERS TO DELAY BUYING OUR
  PRODUCTS RESULTING IN LOWER REVENUES

    The national economy of the United States and the global economy are both
    subject to economic downturns. An economic downturn in any market in which
    we sell our products may have a significant impact on the ability of our
    customers, in both the hospital and pre-hospital markets, to secure adequate
    funding to buy our products or might cause purchasing decisions to be
    delayed. Any delay in purchasing our products may result in decreased
    revenues and also allow our competitors additional time to develop products
    which may have a competitive edge over our M Series products, making future
    sales of our products more difficult.

    For example, as the current economic climate in the U.S. continues to
    soften, many states are experiencing deficits and shortfalls of revenue to
    cover expenditures. As a result, states may cut their spending and support
    to local cities and towns, who then in-turn might reduce their spending for
    capital equipment purchases for their EMS services. If this occurs, we may
    experience slower than expected sales in this customer segment.

  THE WAR ON TERRORISM AND THE IMPACT OF A BIO-TERROR THREAT MAY CAUSE OUR
  CUSTOMERS TO STOP OR DELAY BUYING OUR PRODUCTS, RESULTING IN LOWER REVENUES

    The current war on terrorism and a threat of a bio-terror attack may have a
    significant impact on our customers' ability or willingness to buy our
    products. Our customers may have to divert their funding, earmarked for
    capital equipment purchases to the purchase of other medical equipment and
    supplies to fight any potential bio-terror attack. The war on terrorism may
    cause the diversion of any government funding of hospitals and EMS services
    for capital equipment purchases to the war effort. Such diversion of money
    may result in decreased revenues.

  THE POTENTIAL DISRUPTION IN THE TRANSPORTATION INDUSTRY ON THE COMPANY'S
  SUPPLY CHAIN AND PRODUCT DISTRIBUTION CHANNELS MAY CAUSE DELAYS IN THE
  DELIVERY OF OUR PRODUCTS, RESULTING IN LOWER REVENUES

    Any future disruption in the transportation industry, as the country
    experienced during September 2001, could impact our ability to deliver our
    products to our customers in time to be able to recognize revenues in a
    period, resulting in lower revenues.

  WE CAN BE SUED FOR PRODUCING DEFECTIVE PRODUCTS AND WE MAY BE REQUIRED TO
  PAY SIGNIFICANT AMOUNTS TO THOSE HARMED IF WE ARE FOUND LIABLE, AND OUR
  BUSINESS COULD SUFFER FROM ADVERSE PUBLICITY

    The manufacture and sale of medical products such as ours entail significant
    risk of product liability claims. Our quality control standards comply with
    FDA requirements and we believe that the amount of product liability
    insurance we maintain is adequate based on past product liability claims in
    our industry. We cannot be assured that the amount of such insurance will be
    sufficient to satisfy claims made against us in the future or that we will
    be able to maintain insurance in the future at satisfactory rates or in
    adequate amounts. Product liability claims could result in significant costs
    or litigation. A successful claim brought against us in excess of our
    available insurance coverage or any claim that results in significant
    adverse publicity against us could have a material adverse effect on our
    business, financial condition and results of operations.

  RECURRING SALES OF ELECTRODES TO OUR CUSTOMERS MAY DECLINE

    We typically have recurring sales of electrodes to our customers. Other
    vendors have developed electrode adaptors which allow generic electrodes to
    be compatible with our defibrillators. If we are unable to continue to
    differentiate the superiority of our electrodes over these generic
    electrodes, our future revenue from the sale of electrodes could be reduced.

  FAILURE TO PRODUCE NEW PRODUCTS OR OBTAIN MARKET ACCEPTANCE FOR OUR NEW
  PRODUCTS IN A TIMELY MANNER COULD HARM OUR BUSINESS

    Because substantially all of our revenue comes from the sale of cardiac
    resuscitation devices and related products, our financial performance will
    depend upon market acceptance of, and our ability to deliver and support,
    new products. We cannot be assured that we will be able to produce viable
    products in the time frames we currently estimate. Factors which could cause
    delay in these schedules or even cancellation of our projects to produce and
    market these new products include: research and development delays, the
    actions of our competitors producing competing products and the actions of
    other parties who may provide alternative therapies or solutions which could
    reduce or eliminate the markets for pending products.

    The degree of market acceptance of any of our products will depend on a
    number of factors, including:

    -   our ability to develop and introduce new products in a timely manner;

    -   our ability to successfully implement new product technologies;

    -   the market's readiness to accept new products such as our data
        management products;

    -   the standardization of an automated platform for data management
        systems;

    -   the clinical efficacy of our products and the outcome of clinical
        trials;

    -   the ability to obtain timely regulatory approval for new products; and

    -   the prices of our products compared to the prices of our competitors'
        products.

    If our new products do not achieve market acceptance, our financial
    performance could be adversely affected.

  WE MAY EXPERIENCE SHORT TERM OPERATING FLUCTUATIONS AS WE CONTINUE TO
  INTRODUCE OUR BIPHASIC TECHNOLOGY

    While we believe our biphasic technology offers substantial opportunity for
    future growth, there can be no guarantee that this will occur. In addition,
    in the short term, an industry shift towards biphasic technology could cause
    a lengthening of buying cycles, take additional sales time, and reduce the
    salability of existing inventory and trade-in products. As more customers
    convert to biphasic technology, it may become more difficult for us to sell
    the older monophasic technology products resulting in inventory
    obsolescence. This risk related to a shift towards biphasic technology could
    also be affected by the uncertainty of the governing bodies' recommendations
    concerning biphasic technology.


                                       16

  OUR DEPENDENCE ON SOLE AND SINGLE SOURCE SUPPLIERS EXPOSES US TO SUPPLY
  INTERRUPTIONS AND MANUFACTURING DELAYS CAUSED BY FAULTY COMPONENTS THAT
  COULD RESULT IN PRODUCT DELIVERY DELAYS AND SUBSTANTIAL COSTS TO REDESIGN
  OUR PRODUCTS

    Although we use many standard parts and components for our products, some
    key components are purchased from sole or single source vendors for which
    alternative sources at present are not readily available. For example, we
    currently purchase proprietary components, including capacitors, display
    screens, gate arrays and integrated circuits, for which there are no direct
    substitutes. Our inability to obtain sufficient quantities of these
    components as well as our limited ability to deal with faulty components may
    result in future delays or reductions in product shipments which could cause
    a fluctuation in our results of operations.

    These components could be replaced with alternatives from other suppliers,
    which could involve a redesign of our products. Such a redesign could
    involve considerable time and expense.

    If our manufacturers are unable or unwilling to continue manufacturing our
    components in required volumes, we will have to transfer manufacturing to
    acceptable alternative manufacturers whom we have identified, which could
    result in significant interruptions of supply. The manufacture of these
    components is complex, and our reliance on the suppliers of these components
    exposes us to potential production difficulties and quality variations,
    which could negatively impact the cost and timely delivery of our products.
    Accordingly, any significant interruption in the supply, or degradation in
    the quality, of any component would have a material adverse effect on our
    business, financial condition and results of operations.

  WE MAY NOT BE ABLE TO OBTAIN APPROPRIATE REGULATORY APPROVALS FOR OUR NEW
  PRODUCTS

    The manufacture and sale of our products are subject to regulation by
    numerous governmental authorities, principally the FDA and corresponding
    state and foreign agencies. The FDA administers the Federal Food, Drug and
    Cosmetic Act, as amended, and the rules and regulations promulgated
    hereunder. Some of our products have been classified by the FDA as Class II
    devices and others, such as our automated external defibrillators, have been
    classified as Class III devices. All of these devices must secure a 510(k)
    pre-market notification clearance before they can be introduced into the
    U.S. market. The process of obtaining 510(k) clearance typically takes
    several months and may involve the submission of limited clinical data
    supporting assertions that the product is substantially equivalent to
    another medical device on the market prior to 1976. Delays in obtaining
    510(k) clearance could have an adverse effect on the introduction of future
    products. Moreover, approvals, if granted, may limit the uses for which a
    product may be marketed, which could reduce or eliminate the commercial
    benefit of manufacturing any such product.

    We are also subject to regulation in each of the foreign countries in which
    we sell products. Many of the regulations applicable to our products in such
    countries are similar to those of the FDA. However, the national health or
    social security organizations of certain countries require our products to
    be qualified before they can be marketed in those countries. We cannot be
    assured that such clearances will be obtained.

  IF WE FAIL TO COMPLY WITH APPLICABLE REGULATORY LAWS AND REGULATIONS, THE FDA
  AND OTHER FOREIGN REGULATORY AGENCIES COULD EXERCISE ANY OF THEIR REGULATORY
  POWERS, WHICH COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR BUSINESS

    Every company that manufactures or assembles medical devices is required to
    register with the FDA and to adhere to certain quality systems, which
    regulate the manufacture of medical devices and prescribe record keeping
    procedures and provide for the routine inspection of facilities for
    compliance with such regulations. The FDA also has broad regulatory powers
    in the areas of clinical testing, marketing and advertising of medical
    devices. To ensure that manufacturers adhere to good manufacturing
    practices, medical device manufacturers are routinely subject to periodic
    inspections by the FDA. If the FDA believes that a company may not be
    operating in compliance with applicable laws and regulations, it could take
    any of the following actions:

    -   place the company under observation and re-inspect the facilities;

    -   issue a warning letter apprising of violating conduct;

    -   detain or seize products;

    -   mandate a recall;

    -   enjoin future violations; and


                                       17
<PAGE>

    -   assess civil and criminal penalties against the company, its officers or
        its employees.

    We, like most of our U.S. competitors, have received warning letters from
    the FDA in the past, and may receive warning letters in the future. We have
    always complied with the warning letters we have received. However, our
    failure to comply with FDA regulations could result in sanctions being
    imposed on us, including restrictions on the marketing or recall of our
    products. These sanctions could have a material adverse effect on our
    business.

    If a foreign regulatory agency believes that the company may not be
    operating in compliance with their laws and regulations, they could prevent
    us from selling our products in their country, which could have a material
    adverse effect on our business.

  WE ARE DEPENDENT UPON LICENSED AND PURCHASED TECHNOLOGY FOR UPGRADEABLE
  FEATURES IN OUR PRODUCTS, AND WE MAY NOT BE ABLE TO RENEW THESE LICENSES OR
  PURCHASE AGREEMENTS IN THE FUTURE

    We license and purchase technology from third parties for upgradeable
    features in our products, including 12 lead analysis program, pulse
    oximetry, EtCO2, and NIBP technologies. We anticipate that we will need to
    license and purchase additional technology to remain competitive. We may not
    be able to renew our existing licenses and purchase agreements or to license
    and purchase other technologies on commercially reasonable terms or at all.
    If we are unable to renew our existing licenses and purchase agreements or
    we are unable to license or purchase new technologies, we may not be able to
    offer competitive products.

  FLUCTUATIONS IN CURRENCY EXCHANGE RATES MAY ADVERSELY AFFECT OUR
  INTERNATIONAL SALES

    Our revenue from international operations can be denominated in or
    significantly influenced by the currency and general economic climate of the
    country in which we make sales. A decrease in the value of such foreign
    currencies relative to the U.S. dollar could result in downward price
    pressure for our products or losses from currency exchange rate
    fluctuations. As we continue to expand our international operations,
    downward price pressure and exposure to gains and losses on foreign currency
    transactions may increase.

    We may continue our use of forward contracts and other instruments in the
    future to reduce our exposure to exchange rate fluctuations from
    intercompany accounts receivable denominated in foreign currencies, and we
    may not be able to do this successfully. Accordingly, we may experience
    economic loss and a negative impact on our results of operations and equity
    as a result of foreign currency exchange rate fluctuations.

  WE HAVE LICENSED OUR BIPHASIC TECHNOLOGY TO GE MEDICAL SYSTEMS INFORMATION
  TECHNOLOGIES

    In 2001, we entered into a five-year license agreement with GE Medical
    Systems Information Technologies that permits GE to incorporate our patented
    biphasic waveform technology into their defibrillator and monitoring
    systems. At this time GE has taken only limited action to incorporate our
    technology into their products. However, GE has significantly greater
    resources than we do. If they bring our technology to market, it could
    impact our ability to market and sell our products, potentially lowering our
    revenues.

  OUR CURRENT AND FUTURE INVESTMENTS MAY LOSE VALUE IN THE FUTURE

    We have made a $3.5 million investment in LifeCor, Inc., a development stage
    company and have agreed in certain circumstances to invest another $1.5
    million. In addition, we hold minor investments in ResQSystems, Inc. and
    AED@Home and may in the future invest in the securities of other companies
    and participate in joint venture agreements. These investments and future
    investments are subject to the risks that the entities in which we invest
    will become bankrupt or lose money. Investing in securities involves risks
    and no assurance can be made as to the profitability of any investment. Our
    inability to identify profitable investments could adversely affect our
    financial condition and results of operations. Unless we hold a majority
    position in an investment or joint venture, we will not be able to control
    all of the activities of the companies in which we invest or the joint
    ventures in which we are participating. Because of this, such entities may
    take actions against our wishes and not in furtherance of, and even opposed
    to, our business plans and objectives. These investments are also subject to
    the risk of impasse if no one party exercises ultimate control over the
    business decisions.

                                       18

<PAGE>

  FUTURE CHANGES IN APPLICABLE LAWS AND REGULATIONS COULD HAVE AN ADVERSE
  EFFECT ON OUR BUSINESS

    Although we are not aware of any pending changes in applicable laws and
    regulations governing our industry, we cannot be assured that federal, state
    or foreign governments will not change existing laws or regulations or adopt
    new laws or regulations that regulate our industry. Changes in or adoption
    of new laws or regulations could result in the following consequences that
    would have an adverse effect on our business:

    -   regulatory clearance previously received for our products could be
        revoked;

    -   costs of compliance could increase; or

    -   we may be unable to comply with such laws and regulations so that we
        would be unable to sell our products.

  UNCERTAIN CUSTOMER DECISION PROCESSES MAY RESULT IN LONG SALES CYCLES WHICH
  COULD RESULT IN UNPREDICTABLE FLUCTUATIONS IN REVENUES AND DELAY THE
  REPLACEMENT OF CARDIAC RESUSCITATION DEVICES

    Many of the customers in the pre-hospital market consist of municipal fire
    and emergency medical systems departments. As a result, there are numerous
    decision-makers and governmental procedures in the decision-making process.
    In addition, decisions at hospitals concerning the purchase of new medical
    devices are sometimes made on a department-by-department basis. Accordingly,
    we believe the purchasing decisions of many of our customers may be
    characterized by long decision-making processes, which have resulted in and
    may continue to result in long sales cycles for our products. For example,
    the sales cycles for cardiac resuscitation products typically have been
    between six and nine months, although some sales efforts have taken as long
    as two years.

  OUR INTERNATIONAL SALES EXPOSE OUR BUSINESS TO A VARIETY OF RISKS THAT COULD
  RESULT IN SIGNIFICANT FLUCTUATIONS IN OUR RESULTS OF OPERATIONS

    Approximately 31% of our sales for the six months ended March 30, 2003 were
    made to foreign purchasers and we plan to increase the sale of our products
    to foreign purchasers in the future. As a result, a significant portion of
    our sales is and will continue to be subject to the risks of international
    business, including:

    -   fluctuations in foreign currencies;

    -   trade disputes;

    -   changes in regulatory requirements, tariffs and other barriers;

    -   the possibility of quotas, duties, taxes or other changes or
        restrictions upon the importation or exportation of the products being
        implemented by the United States or these foreign countries;

    -   timing and availability of import/export licenses;

    -   political and economic instability;

    -   difficulties in accounts receivable collections;

    -   difficulties in managing laws;

    -   increased tax exposure if our revenues in foreign countries are subject
        to taxation by more than one jurisdiction;

    -   accepting customer purchase orders governed by foreign laws which may
        differ significantly from U.S. laws and limit our ability to enforce our
        rights under such agreements and to collect damages, if awarded;

    -   war on terrorism;

    -   disruption in the international transportation industry; and


                                       19
<PAGE>

    -   the general economies of these countries in which we transact business.

    As international sales become a larger portion of our total sales, these
    risks could create significant fluctuations in our results of operations.
    These risks could affect our ability to resell trade-in products to domestic
    distributors, who in turn often resell the trade-in products in
    international markets. Our inability to sell trade-in products might require
    us to offer lower trade-in values, which might impact our ability to sell
    new products to customers desiring to trade in older models and then
    purchase newer products.

    We have recently expanded the size and number of our direct sales forces and
    our marketing support for these sales forces. We intend to continue to
    expand these areas, but if our sales forces are not effective, or if there
    is a sudden decrease in the markets where we have direct operations, the
    profitability of these operations and our Company as a whole could be
    adversely affected.

  WE MAY FAIL TO ADEQUATELY PROTECT OR ENFORCE OUR INTELLECTUAL PROPERTY
  RIGHTS OR SECURE RIGHTS TO THIRD PARTY INTELLECTUAL PROPERTY, AND OUR
  COMPETITORS CAN USE SOME OF OUR PREVIOUSLY PROPRIETARY TECHNOLOGY

    Our success will depend in part on our ability to obtain and maintain patent
    protection for our products, methods, processes and other technologies, to
    preserve our trade secrets and to operate without infringing the proprietary
    rights of third parties. To date, we have been issued 23 U.S. patents for
    our various inventions and technologies. Additional patent applications have
    been filed with the U.S. Patent and Trademark Office and are currently
    pending. The patents that have been granted to us are for a definitive
    period of time and will expire. We have filed certain corresponding foreign
    patent applications and intend to file additional foreign and U.S. patent
    applications as appropriate. We cannot be assured as to:

    -   the degree and range of protection any patents will afford against
        competitors with similar products;

    -   if and when patents will be issued;

    -   whether or not others will obtain patents claiming aspects similar to
        those covered by our patent applications;

    -   whether or not competitors will use information contained in our expired
        patents;

    -   whether or not others will design around our patents or obtain access to
        our know-how; or

    -   the extent to which we will be successful in avoiding any patents
        granted to others.

    We have, for example, patents and pending patent applications for our
    proprietary biphasic technology. Our competitors could develop biphasic
    technology that has comparable or superior clinical efficacy to our biphasic
    technology and if our patents do not adequately protect our technology, our
    competitors would be able to obtain patents claiming aspects similar to our
    biphasic technology or our competitors could design around our patents.

    If certain patents issued to others are upheld or if certain patent
    applications filed by others issue and are upheld, we may be:

    -   required to obtain licenses or redesign our products or processes to
        avoid infringement;

    -   prevented from practicing the subject matter claimed in those patents;
        or

    -   required to pay damages.

    There has been substantial litigation regarding patent and other
    intellectual property rights in the medical device industry. Litigation or
    administrative proceedings, including interference proceedings before the
    U.S. Patent and Trademark Office, related to intellectual property rights
    could be brought against us or be initiated by us. Adverse determinations in
    any patent litigation could subject us to significant liabilities to third
    parties, could require us to seek licenses from third parties and could, if
    licenses are not available, prevent us from manufacturing, selling or using
    certain of our products, some of which could have a material adverse effect
    on the Company. In addition, the costs of any such proceedings may be
    substantial whether or not we are successful. For example in fiscal 2002, we
    spent significant amounts in legal costs responding to a lawsuit filed by
    Cardiac Science, Inc. alleging patent infringement.


                                       20
<PAGE>

    Our success is also dependent upon the skills, knowledge and experience,
    none of which is patentable, of our scientific and technical personnel. To
    help protect our rights, we require all U.S. employees, consultants and
    advisors to enter into confidentiality agreements, which prohibit the
    disclosure of confidential information to anyone outside of our company and
    require disclosure and assignment to us of their ideas, developments,
    discoveries and inventions. We cannot be assured that these agreements will
    provide adequate protection for our trade secrets, know-how or other
    proprietary information in the event of any unauthorized use or disclosure
    of the lawful development by others of such information.

  RELIANCE ON OVERSEAS VENDORS FOR SOME OF THE COMPONENTS FOR OUR PRODUCTS
  EXPOSES US TO INTERNATIONAL BUSINESS RISKS, WHICH COULD HAVE AN ADVERSE
  EFFECT ON OUR BUSINESS

    Some of the components we use in our products are acquired from foreign
    manufacturers, particularly countries located in Europe and Asia. As a
    result, a significant portion of our purchases of components is subject to
    the risks of international business. The failure to obtain these components
    as a result of any of these risks can result in significant delivery delays
    of our products, which could have an adverse effect on our business.

  WE RELY HEAVILY ON SEVERAL EMPLOYEES WHO MAY LEAVE, AND IT MAY BE DIFFICULT
  TO RECRUIT EMPLOYEES

    Our future operating results will depend in part upon the contributions of
    the persons who will serve in senior management positions and the continued
    contributions of key technical personnel, some of who would be difficult to
    replace. Our future success will depend in part upon our ability to attract
    and retain highly qualified personnel, particularly product design
    engineers. It could be difficult and/or expensive to recruit and retain
    employees in a cost effective manner. There can be no assurance that such
    key personnel will remain in our employment or that we will be successful in
    hiring qualified personnel. Any loss of key personnel or the inability to
    hire or retain qualified personnel could have a material adverse effect on
    our business, financial condition and results of operations.

  WE MAY ACQUIRE OTHER BUSINESSES, AND WE MAY HAVE DIFFICULTY INTEGRATING
  THESE BUSINESSES OR GENERATING AN ACCEPTABLE RETURN FROM ACQUISITIONS

    We may attempt to acquire or make strategic investments in businesses and
    other assets. Such acquisitions will involve risks, including:

    -   the inability to achieve the strategic and operating goals of the
        acquisition;

    -   the inability to raise the required capital to fund the acquisition;

    -   difficulty in assimilating the acquired operations and personnel;

    -   disruption of our ongoing business; and

    -   inability to successfully incorporate acquired technology into our
        existing product lines and maintain uniform standards, controls,
        procedures and policies.

  PROVISIONS IN OUR CHARTER DOCUMENTS, OUR SHAREHOLDER RIGHTS AGREEMENT AND
  STATE LAW MAY MAKE IT HARDER FOR OTHERS TO OBTAIN CONTROL OF ZOLL EVEN
  THOUGH SOME STOCKHOLDERS MIGHT CONSIDER SUCH A DEVELOPMENT TO BE FAVORABLE

    Our board of directors has the authority to issue up to 1,000,000 shares of
    undesignated preferred stock and to determine the rights, preferences,
    privileges and restrictions of such shares without further vote or action by
    our stockholders. The rights of the holders of common stock will be subject
    to, and may be adversely affected by, the rights of the holders of any
    preferred stock that may be issued in the future. The issuance of preferred
    stock could have the effect of making it more difficult for third parties to
    acquire a majority of our outstanding voting stock. In addition, our
    restated articles of organization provide for staggered terms for the
    members of the board of directors which could delay or impede the removal of
    incumbent directors and could make a merger, tender offer or proxy contest
    involving the Company more difficult. Our restated articles of organization,
    restated by-laws and applicable Massachusetts law also impose various
    procedural and other requirements that could delay or make a merger, tender
    offer or proxy contest involving us more difficult.


                                       21

<PAGE>

    We have also implemented a so-called poison pill by adopting our
    shareholders rights agreement. This poison pill significantly increases the
    costs that would be incurred by an unwanted third party acquirer if such
    party owns or announces its intent to commence a tender offer for more than
    15% of our outstanding common stock. The existence of this poison pill could
    delay, deter or prevent a takeover of the Company.

    All of these provisions could limit the price that investors might be
    willing to pay in the future for shares of our common stock which could
    preclude our shareholders from recognizing a premium over the prevailing
    market price of our stock.

  WE HAVE ONLY ONE MANUFACTURING FACILITY FOR EACH OF OUR MAJOR PRODUCTS AND
  ANY DAMAGE OR INCAPACITATION OF EITHER OF THE FACILITIES COULD IMPEDE OUR
  ABILITY TO PRODUCE THESE PRODUCTS

    We have only one manufacturing facility, which produces defibrillators and
    one separate manufacturing facility which produces electrodes. Damage to
    either facility could render us unable to manufacture the relevant product
    or require us to reduce the output of products at the damaged facility. This
    could materially and adversely impact our business, financial condition and
    results of operations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We have cash equivalents and marketable securities that primarily consist of
money market accounts and fixed rate asset-backed corporate securities. The
majority of these investments have maturities within one to five years. We
believe that our exposure to interest rate risk is minimal due to the nature of
our investments and that fluctuations in interest rates would not have a
material adverse effect on our results of operations.

We have international offices in Canada, United Kingdom, Netherlands, France,
Germany, and Australia. These subsidiaries transact business in their functional
or local currency. Therefore, we are exposed to foreign currency exchange
risks and fluctuations in foreign currencies, along with economic and political
instability in the foreign countries in which we operate, all of which could
adversely impact our results of operations and financial condition.

We use forward contracts to reduce our exposure to foreign currency risk due to
fluctuations in exchange rates underlying the value of intercompany accounts
receivable denominated in foreign currencies. A forward contract obligates us to
exchange predetermined amounts of specified foreign currencies at specified
exchange rates on specified dates. These forward contracts are denominated in
the same currency in which the underlying foreign currency receivables are
denominated and bear a contract value and maturity date that approximate the
value and expected settlement date, respectively, of the underlying
transactions. Unrealized gains and losses on open contracts at the end of each
accounting period, resulting from changes in the fair value of these contracts,
are recognized in earnings generally in the same period as exchange gains and
losses on the underlying foreign denominated receivables are recognized. Gains
and losses on forward contracts and foreign denominated receivables are included
in investment and other income.

We had a forward exchange contract outstanding in the notional amount of $4.3
million at March 30, 2003. This contract serves as a hedge of a substantial
portion of our Euro-denominated intercompany balances. The fair value of this
foreign currency derivative contract outstanding at March 30, 2003 was
$4,296,000. A sensitivity analysis of a change in the fair value of the
derivative foreign exchange contract outstanding at March 30, 2003 indicates
that, if the U.S. dollar weakened by 10% against the Euro, the fair value of
this contract would decrease by $430,000. Conversely, if the U.S. dollar
strengthened by 10% against the Euro, the fair value of this contract would
increase by $391,000. Any gains and losses on the fair value of the derivative
contract would be largely offset by losses and gains on the underlying
transaction. These offsetting gains and losses are not reflected in the analysis
above.

ITEM 4. CONTROLS AND PROCEDURES

Within 90 days prior to the filing of this report with the SEC, an evaluation
had been performed under the supervision and with the participation of the
Company's management, including the Chief Executive Officer and Chief Financial
Officer, of the effectiveness of the design and operation of the Company's
disclosure controls and procedures. Based upon that evaluation, the Company's
management, including the CEO and CFO, concluded that the Company's disclosure
controls and procedures were effective as of March 30, 2003. There have been no
significant changes in the Company's internal controls or in other factors that
could significantly affect internal controls subsequent to March 30, 2003.
