              CONSOLIDATED CONDENSED NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
                                       JUNE 30, 1999


1.       ORGANIZATION AND CAPITALIZATION OF THE COMPANY

         Cardiac Science, Inc. (the "Company") was incorporated on May 20, 1991
to develop, manufacture and market software driven non-invasive (non-surgical)
fully automatic external cardioverter defibrillator devices ("AECD") (the
"Products") to treat persons suffering from or at high risk of life-threatening
ventricular tachyarrhythmias. The Products, all of which are still under
development, are designed to continuously monitor, quickly detect and then
automatically, through transmission of electrical energy charges to the
patient's heart, terminate the ventricular tachyarrhythmia (abnormally fast
heart rate) and/or ventricular fibrillation (quivering of the heart following
tachyarrhythmia, which usually results in death) and convert the patients heart
back to a normal rhythm. The key benefit of the Company's AECD technology is its
ability to provide immediate defibrillation therapy without human intervention
for hospitalized patients at risk of cardiac arrest.

         On April 11, 1997, the Company acquired Innovative Physician
Services, Inc. (d.b.a. Diagnostic Monitoring). The Company sold substantially
all of the assets of Diagnostic Monitoring on December 31, 1998 (see notes 4
and 5).

2.       CONTINUED EXISTENCE

         Additional capital is needed to fulfill the Company's current
marketing, research and product development goals. Through June 30, 1999, the
Company incurred losses of approximately $14.3 million. Recovery of the
Company's assets is dependent upon future events, the outcome of which is
indeterminable. Additionally, successful completion of the Company's development
program and its transition to attain profitable operations is dependent upon
achieving a level of revenues adequate to support the Company's cost structure.
The Company anticipates that its current cash balance will be sufficient to meet
the Company's cash requirements through August 31, 1999. Given the current
applications of cash, the Company expects that additional capital will be
necessary to sustain growth and viability. In this respect, the Company is
considering a number of alternatives, including additional equity financings and
corporate partnerships. There can be no assurance that any such transactions
will be available at terms acceptable to the Company, if at all, or that any
financing transaction will not be dilutive to current stockholders, or that the
Company will have sufficient working capital to fund future operations. If the
Company is not able to raise additional funds, it may be required to
significantly curtail or cease its operating activities. The accompanying
financial statements have been prepared assuming that the Company will continue
as a going concern.

3.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         In the opinion of the Company's management, the accompanying
consolidated condensed unaudited financial statements include all adjustments
(which consist only of normal recurring adjustments) necessary for a fair
presentation of its financial position at June 30, 1999 and results of
operations and cash flows for the periods presented. Although the Company
believes that the disclosures in these financial statements are adequate to make
the information presented not misleading, certain information and disclosures
normally included in financial statements prepared in accordance with generally
accepted accounting principles have been condensed or omitted and should be read
in conjunction with the Company's audited financial statements

                                                                             6

included in the Company's 1998 Annual Report on Form 10-KSB. Results of
operations for the six months ended June 30, 1999 are not necessarily
indicative of results for the full year.

4.       INVESTMENT IN UNCONSOLIDATED AFFILIATE

         On December 31, 1998, the Company acquired a 7.7% voting interest in
Biosensor as partial consideration for the sale of substantially all of the
assets of Diagnostic Monitoring. The Company accounts for this investment using
the equity method of accounting in accordance with Accounting Principles Board
Opinion No. 18.

5.       DISCONTINUED OPERATIONS

         On December 31, 1998, the Company completed the sale of substantially
all of Diagnostic Monitoring's assets to Biosensor, a Minnesota corporation,
pursuant to an Agreement for Purchase and Sale of Assets dated December 31,
1998. The Company received, in consideration for the sale, 1,440,000 shares of
common stock of Biosensor valued at $115,000. In addition, Biosensor assumed
certain liabilities amounting to approximately $107,000.

         The Company has restated its prior financial statements to present the
operating results of Diagnostic Monitoring as a discontinued operation. Included
in the loss from discontinued operations is amortization of goodwill of $32,856.
Operating results from discontinued operations are as follows:

ITEM 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

GENERAL

         The following discussion should be read in conjunction with the
consolidated financial statements and notes thereto set forth elsewhere in this
Quarterly Report on Form 10-QSB.

         We are engaged in the development of non-invasive fully-automatic
external cardioverter defibrillation devices for the treatment of ventricular
tachyarrhythmias that lead to cardiac arrest. We commenced operations in May
1991. Until our acquisition of Diagnostic Monitoring in April 1997, our
operations consisted primarily of research and development activities and
clinical FDA testing. Diagnostic Monitoring manufactured PC-based Holter
Electrocardiogram systems and Ambulatory Holter recorders and distributed these
products in over 40 countries. We sold substantially all of the assets of
Diagnostic Monitoring on December 31, 1998 (see note 5 of the consolidated
financial statements).

         Cardiac arrest is the single largest cause of death in the United
States and Europe. Our mission is to increase the survival rate of cardiac
arrest victims and create a new standard of care through the development and
commercialization of our proprietary automatic defibrillation technology.

         We have three products under development that utilize our proprietary
technology. Our initial product, the Powerheart, is a bedside
defibrillator-monitor designed for in-hospital use. The Powerheart attaches
prophylactically to at risk cardiac patients for the purpose of providing
fully-automatic detection and treatment of life-threatening tachyarrhythmias
(abnormal rhythms of the heart), such as ventricular tachycardia (dangerously
rapid heart rate) and ventricular fibrillation (quivering of the heart), that
lead to cardiac arrest. The second product under development, the RHYTHMx ECD
module, is designed for integration into bedside patient monitoring systems.
Functionally, the RHYTHMx ECD module extends patient monitoring systems beyond
diagnostics to provide patients who suffer life-threatening tachyarrhythmias
with the added protection of automatic therapy delivery without human
intervention. . We believe the Powerheart and RHYTHMx ECD will be ideally suited
for hospitalized patients temporarily at risk (periods ranging from days to
months) of suffering cardiac arrest. . The third product under development is a
fully-automatic public access defibrillator that can be used by first responders
and other non-technical individuals outside of the hospital environment.

         In December 1998, we entered into a five-year exclusive distribution
and licensing agreement with the world leader in external defibrillation,
Medtronic Physio-Control, a subsidiary of Medtronic, Inc. Medtronic
Physio-Control will market the Powerheart in the U.S., Canada and selected
European countries, and also has been licensed to integrate the AECD
Technology into Medtronic's LIFEPAK-Registered Trademark- line of in-hospital
external defibrillators. We have signed distribution agreements to date
covering 24 other international markets giving Cardiac Science representation
in 35 countries.

         We have received 510(k) clearance from the U.S. Food and Drug
Administration for the clinical version of the Powerheart and have also received
FDA 510(k) clearance for its proprietary AECD Technology platform, which we plan
to integrate into third-party manufactured bedside monitoring and defibrillator
systems.

         We have been issued one patent, and have one additional patent under
exclusive license. We are in the process of filing additional patents relating
to our proprietary technology.

                                                                             9

RESULTS OF OPERATIONS

         Research and development expenses increased to $1,072,282 and
$1,669,310, respectively, for the three and six months ended June 30, 1999, from
$561,520 and $979,799, respectively, for the three and six months ended June 30,
1998. This increase was due to engineering and pre-production costs associated
with the commercialization of the Powerheart. Included in these costs were
increases in personnel costs and related fringes, and costs associated with
independent engineering contractors.

         Selling expenses increased to $404,672 and $679,921, respectively, for
the three and six months ended June 30, 1999, from $71,943 and $121,994,
respectively for the three and six months ended June 30, 1998. The increase was
a result of pre-marketing expenses related to the Powerheart including costs
associated with the development of marketing literature and the addition of
personnel and related fringes.

         General and administrative expenses increased to $468,513 and $749,625,
respectively, for the three and six months ended June 30, 1999, from $356,235
and $608,400 for the three and six months ended June 30, 1998. The increase in
expenses for the quarter and six months ended June 30, 1999 as compared to the
same periods in 1998 included personnel costs and related fringes, consulting
and professional fees.

         Interest expense, net, decreased to $460 and $3,632 for the three month
and year to date period ended June 30, 1999 as compared to $5,097 and $9,126,
respectively, for the same periods in the prior year due to the reduction of the
bank line of credit and investment of the proceeds from private placements.

LIQUIDITY AND CAPITAL RESOURCES

         At June 30, 1999, we had cash and cash equivalents of $1,165,120 and a
working capital deficit of $218,457 as compared to cash and cash equivalents of
$1,247,602 and negative working capital of $549,898 at December 31, 1998. From
inception, our sources of funding for operations were derived from equity
placements aggregating approximately $14,900,000. We have incurred losses of
$14,322,475 since inception, and we expect to incur substantial additional
operating losses as a result of expenditures related to marketing and sales
efforts, research and product development activities and costs associated with
the development of a commercial model and pre-production costs for the
Powerheart. The timing and amounts of these expenditures will depend upon many
factors, some of which are beyond our control, such as the requirements for and
time required to obtain approval of 510(k) applications or other regulatory
approvals, the progress of research and development programs, and market
acceptance of our products.

         We have raised $3,700,000 in a series of private equity placements for
the six month period ending June 30, 1999. In connection with these private
placements we paid certain fees and expenses. Additional capital will be needed
to fulfill our marketing, research and product development goals. Successful
completion of our development program for our products and transition to attain
profitable operations is dependent upon achieving a level of revenues adequate
to support the required cost structure.

         We anticipate that the current cash balance will be sufficient to meet
our cash requirements into September 1999. Given the current applications of
cash, we expect that additional capital will be necessary to sustain growth and
viability. In this respect, we are considering a number of alternatives,
including additional equity financings and corporate partnerships. There can be
no assurance that any such transactions will be available on terms acceptable to
us, if at all, or that any financing transaction will not be dilutive to current
stockholders, or that we will have sufficient working capital to fund future
operations. If we are not able to raise additional funds, we may be required to
significantly curtail or cease our operating activities. The accompanying
financial statements have been prepared assuming that we will continue as a
going concern.

                                                                            10

YEAR 2000 ISSUE

         In the next six months, many companies will face a potentially serious
information systems (computer) problems because many software applications and
operational programs written in the past may not properly recognize calendar
dates beginning in the Year 2000. This problem could force computers to either
shut down or provide incorrect information and could result in an inability to
process transactions or engage in normal business activities. Based on a recent
assessment, we believe that the software we use will not be impacted by the Year
2000 issue. We believe that most of our existing information systems equipment,
primarily composed of personal computers, are Year 2000 compliant. We intend to
replace those systems that are not compliant, the cost of which is not
anticipated to be material. In addition, our initial product, the Powerheart,
and our proprietary technology are not expected to encounter any problems with
the Year 2000 issue. We have initiated communications with our vendors regarding
the Year 2000 Issue. Costs spent to date on the Year 2000 issue are minimal and
we do not expect to incur additional costs which would be considered material.
If we determine that a particular vendor will be impacted by this problem, we
may attempt to identify additional or replacement vendors, which could delay
accessibility of the products and/or services provided by such vendors. Such a
delay or failure to identify an additional or replacement vendor could have a
material adverse effect on our business, operating results and financial
condition.

FORWARD LOOKING STATEMENTS

         Except for the historical information contained herein, the matters
discussed herein are forward looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995. The forward looking statements
contained in this Quarterly Report on Form 10-QSB are subject to various risks,
uncertainties and other factors that could cause actual results to differ
materially from the results anticipated in such forward looking statements.
Included among the important risks, uncertainties and other factors are those
hereinafter discussed, the accuracy of which is necessarily subject to risks and
uncertainties.

         Few of the forward looking statements in this Quarterly Report on Form
10-QSB deal with matters that are within our unilateral control. There is
substantial regulation of the manufacture and sale of medical products,
including many of our products, by governmental agencies in the United States
and foreign countries. These government agencies often have considerable
discretion in determining whether and when to approve the marketing of our
products that have not yet received such approval.

         The availability of equity and debt financing to our company is
affected by, among other things, domestic and world economic conditions and the
competition for funds. Potential investors and lenders will be influenced by
their evaluations of our products and comparisons with alternative investment
opportunities.

         Many of the our competitors have greater financial resources and
technical capabilities than we do, which may enable such competitors to design
and produce superior products or to market their products in a manner that
achieves commercial success even in the face of technical superiority on the
part of our products.

         Our patents may not offer effective protection against competitors.
Competitors may be able to design around our patents or employ technologies not
covered by such patents. In addition, our patents may be challenged, and even if
such patents are upheld, the diversion of financial and human resources
associated with patent litigation could adversely affect our company. We may be
found to be violating the patents of others and forced to obtain a license under
such patents or modify the design of its products.

                                                                            11

         Rapid technological developments are expected to continue in the
industries in which we compete. We may not be able to develop, manufacture and
market products which meet changing user requirements or which successfully
anticipate or respond to technological changes in a cost-effective and timely
manner.

                                                                           12

                $2,800,000 to foreign investors in an offshore transaction
                pursuant to Regulation S promulgated under the Securities Act of
                1933. In connection with the offering, we are obligated to pay a
                finder a fee equal to ten percent of the gross proceeds of the
                sale, payable in cash or common stock.

                On April 1, 1999, we sold 10,000 shares of common stock to a
                consultant in consideration for $21,250 of services rendered.

                $2.50 per share, to Medtronic Physio-Control Corp. for an
                aggregate purchase price of $400,000. The securities were sold
                pursuant to Section 4(2) of the Securities Act of 1933 and
                Regulation D promulgated thereunder.
