CARDIAC SCIENCE, INC.

CONSOLIDATED CONDENSED NOTES TO FINANCIAL STATEMENTS (Unaudited)

(Dollars in thousands, except per share
amounts)

1.       Organization and Description of the Business

Cardiac Science, Inc. (the Company) was incorporated in May 1991 and develops, manufactures and markets portable public access defibrillators and a
fully-automatic in-hospital bedside defibrillator-monitor that continuously monitors cardiac patients, instantly detects the onset of life-threatening abnormal heart rhythms, and, when appropriate, delivers defibrillation shocks within seconds and
without human intervention to convert the heart back to its normal rhythm.  The Companys core technology platform consists of its proprietary arrhythmia detection and discrimination software (RHYTHMx®), which
is combined with its proprietary STAR®Biphasic defibrillation hardware and electrode technology to create the only fully automatic in-hospital cardioverter defibrillator (the Powerheart®
CRM® or CRM) and a unique semi-automatic, or automated defibrillator, (the Powerheart AED or AED) for use in out-of-hospital settings.  The Companys Powerheart®
Cardiac Rhythm Module and Powerheart®brand AEDs along with Diascope G2® patient monitoring products are marketed by its direct sales force in the United States and by international distributors
around the world.

On July 1, 2000, the Company acquired Cadent Medical Corporation, a privately held company, for an aggregate of
4,500,000 restricted shares of the Companys common stock.

On September 26, 2001, the Company acquired Survivalink Corporation, a
privately held company, for $10,500 in cash, $25,800 in senior secured promissory notes, and 18,150,000 shares of the Companys common stock.

On November 30, 2001, the Company acquired 94.7% of Artema Medical AB for 4,150,976 shares of common stock and approximately $215 in cash.  Effective April 1,
2003, the Company acquired the remaining minority interest for $1,299 in cash.

On May 29, 2003, the Company acquired Lifetec
Medical Limited, its U.K. distributor, for $383 in cash.

2.       Continued Existence

The Company believes its current cash balances, combined with net cash that it expects to generate from operations, will sustain its ongoing operations for at least
twelve months. In the event that the Company requires additional cash to support its operations during the next twelve months, it will attempt to raise the required capital through either debt or equity arrangements. The Company cannot provide any
assurance that the required capital will be available on acceptable terms, if at all, or that any financing activity will not be dilutive to current stockholders of the Company. If the Company is not able to raise additional funds, it may be
required to significantly curtail its operations and this would have an adverse effect on its financial position, results of operations and cash flows.

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, 2003 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
included in the Companys 2002 Annual Report on Form 10-K.  Results of operations for the six months ended June 30, 2003 are not necessarily indicative of results for the full year.

Company placed $525 of CRM units at customer locations. The Company retains title to these units and such amounts were transferred to property and equipment where they are being depreciated over a five-year period.

Goodwill and Intangibles

In
accordance with SFAS No. 142, Goodwill and Other Intangible Assets, which became effective January 1, 2002, goodwill and other intangible assets with indeterminate lives are no longer subject to amortization but are tested for impairment
annually or whenever events or changes in circumstances indicate that the asset might be impaired.  The Company has also reclassified the balance of acquired workforce to goodwill.  Accordingly, no goodwill or acquired workforce
amortization has been recognized since December 31, 2001.  Other intangible assets with finite lives continue to be subject to amortization, and any impairment is determined in accordance with SFAS No. 144, Accounting for the Impairment
or Disposal of Long-Lived Assets.   Estimated intangible asset amortization expense (based on existing intangible assets) for the years ended December 31, 2003, 2004, 2005, 2006 and 2007 is $1,506, $1,183, $1,183, $1,183 and $1,183,

Product Warranty

Our products are generally

Stock Based Compensation

On December 31, 2002, the FASB issued Statement No. 148 (SFAS No. 148), Accounting for Stock-Based CompensationTransition and
Disclosure, which amends SFAS No. 123, Accounting for Stock-Based Compensation. SFAS No. 148 allows for three methods of transition for those companies that adopt

##### Table of Contents

SFAS No. 123s provisions for fair value recognition. SFAS No. 148s transition guidance and provisions for annual and interim disclosures are effective for
fiscal periods ending after December 15, 2002. The Company will not adopt fair value accounting for employee stock options under SFAS No. 123 and SFAS No. 148.

The Company has adopted the disclosure-only provisions of SFAS No. 123, Accounting for Stock-Based Compensation. SFAS No. 123 defines a fair value based method
of accounting for an employee stock option. Fair value of the stock option is determined considering factors such as the exercise price, the expected life of the option, the current price of the underlying stock, expected dividends on the stock, and
the risk-free interest rate for the expected term of the option. Under the fair value based method, compensation cost is measured at the grant date based on the fair value of the award and is recognized over the service period. Pro forma disclosures
are required for entities that elect to continue to measure compensation cost under the intrinsic method provided by Accounting Principles Board Opinion (APB) No. 25.

Additionally, in accordance with SFAS 123 and EITF Issue No. 96-18, Accounting for Equity Instruments That are Issued to Other Than Employees for Acquiring, or in
Conjunction with Selling Goods or Services, the Company measures stock based non-employee compensation at fair value.

Under SFAS
No. 123, stock based compensation expense related to stock options granted to consultants is recognized as the stock options are earned. The fair value of the stock options granted is calculated at each reporting date using the Black-Scholes option
pricing model. As a result, the stock based compensation expense will fluctuate as the fair market value of the Companys stock fluctuates.

Had compensation costs been determined based upon the fair value at the grant date, consistent with the methodology prescribed under SFAS No. 123, the Companys
total stock-based compensation cost, proforma net loss, and proforma net loss per share, basic and diluted, would have been as follows:

Recent Pronouncements

In June 2002, the Financial Accounting Standards Board (FASB) issued SFAS No. 146 (SFAS No. 146), Accounting for Exit or Disposal
Activities. SFAS No. 146 is effective for exit or disposal activities that are initiated after December 31, 2002. SFAS No. 146 addresses significant issues regarding the recognition, measurement, and reporting of costs that are associated with
exit and disposal activities, including restructuring activities that were previously accounted for pursuant to the guidance that the Emerging Issues Task Force (EITF) has set forth in EITF Issue No. 94-3, Liability Recognition for Certain
Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring). The scope of SFAS No. 146 also includes (1) costs related to terminating a contract that is not a capital lease,
and (2) termination benefits that employees who are involuntarily terminated receive under the terms of a one-time benefit arrangement that is not an ongoing benefit arrangement or an individual deferred-compensation contract. The Companys
adoption of SFAS No. 146 had an impact on its accounting for its corporate restructuring and relocation (see Note 6).

In November 2002,
the FASB issued Interpretation No. 45 (FIN 45),Guarantors Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees Of Indebtedness Of Others, an Interpretation

9



---

##### Table of Contents

of FASB Statements No. 5, 57, and 107 and Rescission of FASB Interpretation No. 34. FIN 45 relates to the accounting for and disclosure of guarantees and addresses (1)
an obligation to stand ready to perform over the term of the guarantee in the event that the specified triggering events or conditions occur and (2) a contingent obligation to make future payments if those triggering events or conditions occur. FIN
45 excludes certain types of guarantees from its initial recognition and measurement, including guarantees accounted for as derivative instruments and hedging activities, guarantees relating to performance of non-financial assets that are owned by
the guaranteed party (e.g., product warranties), guarantees issued in a business combination that represent contingent consideration, and others. They are subject to its disclosure requirements. The disclosure requirements are effective for
financial statements of interim and annual periods ending after December 15, 2002. The initial recognition and initial measurement provisions should be applied only on a prospective basis to guarantees issued or modified after December 31, 2002. The
guarantors previous accounting for guarantees issued prior to the initial application date of FIN 45 should not be revised or restated to reflect the effect of the new recognition and measurement provisions. The adoption of FIN 45 did not have
a material impact on the Companys consolidated financial statements.

EITF Issue No. 00-21 (the Issue 00-21),
Revenue Arrangements with Multiple Deliverables addresses the accounting for multiple element revenue arrangements which involve more than one deliverable or unit of accounting in circumstances, where the delivery of those units takes
place in different accounting periods. Issue 00-21 requires disclosure of the accounting policy for revenue recognition of multiple element revenue arrangements and the nature and description of such arrangements. It will be effective for revenue
arrangements entered into in fiscal periods beginning after June 15, 2003. The Company does not expect that the adoption of Issue 00-21 will have a significant impact on the Companys consolidated financial statements.

In May 2003, the FASB issued Statement of Financial Accounting Standards No. 150, Accounting For Certain Financial Instruments with Characteristics of both
Liabilities and Equity (SFAS 150).  SFAS 150 establishes standards for how an issuer classifies and measures in its statement of financial position certain financial instruments with characteristics of both liabilities and equity.
 It requires that an issuer classify a financial instrument that is within its scope as a liability (or an asset in some circumstances) because that financial instrument embodies an obligation of the issuer.  SFAS 150 is effective for
financial instruments entered into or modified after May 31, 2003, and otherwise shall be effective at the beginning of the first interim period beginning after June 15, 2003.  The Company does not believe that the adoption of SFAS 150 will
have a material impact on its consolidated financial position, results of operations, or cash flows.

4.       Segment reporting

The Company follows the provisions of SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information.SFAS No. 131 established
standards for reporting information about operating segments in annual financial statements and requires selected information about operating segments in interim financial reports issued to stockholders. It also established standards for related
disclosures about products and services, geographic areas and major customers. An operating segment is defined as a component of an enterprise that engages in business activities from which it may earn revenues and incur expenses whose separate
financial information is available and is evaluated regularly by the Companys chief operating decision makers, or decision making group, to perform resource allocations and performance assessments.

The Companys chief operating decision makers are the Executive Management Team which is comprised of the Chief Executive Officer and senior executive officers
of the Company. Based on evaluation of the Companys financial information, management believes that the Company operates in one reportable segment with its various product lines that service the external defibrillation and cardiac monitoring
industry. The product lines include AEDs and related accessories, Powerhearts, electrodes and related accessories, and emergency defibrillators, monitors and related accessories.

The Companys chief operating decision makers evaluate revenue performance of product lines, both domestically and internationally, however, operating, strategic
and resource allocation decisions are not based on product line performance, but rather on the Companys overall performance in its operating segment.

5.       Artema Restructuring and Planned Disposal of the MCS Gas
Business

As part of the Artema acquisition, the Company had developed a plan to restructure the operations of the manufacturing
facility in Denmark (the plan). Originally, the Company recorded certain purchase price adjustments in connection with the plan totaling $3,064. The plan included plant and facility closure costs that were either contractually obligated
or were incremental in nature, adjustments to fair market value for owned facilities to be disposed of based on market assessments, adjustments to fair value for raw materials that would not be converted into finished goods and certain severance
related costs for employees in closed facilities that the Company was obligated to pay upon execution of the plan.

The plan, which
included closing the manufacturing facility in Denmark, relocating from the then current facility in Copenhagen, as well as discontinuing or subcontracting the manufacturing of certain product lines, was completed in the quarter ended September 30,
2002. Additionally, an existing defibrillator product line and the accompanying future service obligations were sold to a European company as part of the plan. The Company sold related inventories, manufacturing assets and the right to manufacture
and sell the existing products for consideration of cash and future royalty payments based on future units produced. No gain or loss was recognized on the transaction as the disposal of these assets was contemplated as a part of the plan. Upon
execution of the plan, the Company recorded an additional $905 of purchase price adjustments to reflect the fair value of the assets disposed.

The Company also entered into a licensing agreement with the European company granting them the right to use Cardiac Sciences proprietary bi-phasic
defibrillation technology. In consideration, the Company received an upfront payment of $487 and will receive eight quarterly installments over the next 2 years totaling $500. The total licensing revenue of $987 will be recognized on a pro-rata
basis over the next seven years, which is the term of the agreement and, accordingly, the Company recognized $70 of licensing revenue in the six months ended June 30, 2003.

Also as part of the Artema acquisition, the Company identified the MCS gas business, located in Stockholm, Sweden, as a business segment acquired in a business
combination accounted for as a purchase, to be disposed of.

##### Table of Contents

The MCS gas business designs, develops and manufactures gas analyzers, which are sold to OEM patient monitoring customers. The MCS gas business is a distinct and separate
business unit. The Company was, for the period from acquisition through November 30, 2003 accounting for this in accordance with EITF 87-11, Allocation of Purchase Price to Assets to be Sold,which requires that the operations of the MCS gas
business be excluded from the consolidated operating results of the Company. The Company had initially estimated that the net loss of the MCS gas business from the acquisition date until disposition would be approximately $1,017 and had included
this as a liability assumed in the acquisition and included it in the purchase price allocation. This estimated net loss was subsequently revised to an estimated loss of $306. Accordingly, a net loss of $306 has been excluded for the one year period
from acquisition through November 30, 2002 and net income of $130 and $237 for the three and six months ended June 30, 2003, respectively, has been recorded as discontinued operations in accordance with EITF 90-6, Accounting for Certain Events
not Addressed in Issue No. 87-11 Relating to Acquired Operating Unit to be Sold.

In February 2003, the Company paid off
Artemas outstanding line of credit with a Swedish bank. Effective April 1, 2003, the Company acquired the remaining 5.3% minority interest in Artema for $1,299 in cash.

6.       Corporate Relocation and Restructuring

During the first
quarter of 2003, the Company relocated its corporate headquarters, expanded its manufacturing capacity, and consolidated its accounting and finance functions in Irvine, California.

The costs which were incurred are included in general and administrative expenses in the accompanying consolidated income statement for the six months ended June 30,
2003.  All expansion, relocation, and restructuring activities were completed in the second quarter of 2003 and there are no future expected costs.

The following is a breakdown of the accrual recorded related to the expansion, relocation and restructuring activities:

The accrual represents costs recognized pursuant to FASB Statement No. 146, Accounting for Costs Associated with
Exit or Disposal Activities and SEC Staff Accounting Bulletin (SAB) 100, Restructuring and Impairment Charges.  The Company committed to a sufficiently detailed plan that identified significant actions to be taken and the
activities that will not be continued.  The plan was completed during the quarter ended June 30, 2003 and there were no significant changes to the plan.  The involuntary one-time employee-termination arrangement established the benefits to
be paid to employees and specifically identified the classifications or functions of those employees, their locations, and the expected completion date.  All employees were informed about the terms of the benefit arrangement, including the
benefits that employees will receive upon termination (including but not limited to cash payments), in sufficient detail to enable employees to determine the type and amount of benefits they will receive.  The Company reviewed the net book
value of leasehold improvements to be abandoned in certain facilities in accordance with SFAS No. 144, and has appropriately recorded an adjustment to accelerate the related depreciation over the revised useful life through their cease-use
dates.

7.       Distribution and License Agreement

In December 1998, the Company entered into a five-year exclusive distribution and licensing agreement with Medtronic Physio-Control (MPC), a subsidiary of
Medtronic, Inc. (Medtronic). Under the original agreement, MPC had the exclusive right to market the Powerheart in the United States and Canada. In May 1999, the agreement was expanded to include the United Kingdom, Germany, France, and
certain Scandinavian countries. Subsequent to December 31, 2000, MPC provided the Company with notice that, among other things, the acquisition of Survivalink, a significant competitor of MPC, placed MPC at substantial risk of violating restrictions
placed on Medtronic by the Federal Trade Commission in connection with Medtronics acquisition of Physio-Control. MPC believed these restrictions, among other things, directly impacted MPCs ability to continue its relationship with
Cardiac Science. MPC had stated that in light of such fact, it believed it to be in the best interests of the parties to terminate the agreement. The Company entered into a settlement agreement and mutual release with MPC in February 2002. The terms
of this settlement agreement provided that MPC return to the Company, at no charge, approximately 220 Powerheart units, which MPC had previously purchased and paid for, in substantially the same condition in which the units were originally sold to
MPC. Additionally, the Company owed MPC $1,100 pursuant to a senior secured promissory note issued by the Company to MPC in the merger transaction between the Company and Survivalink. This $1,100 is part of the $25,800 of senior secured promissory
notes issued in the Survivalink merger. Pursuant to this settlement agreement, MPC agreed to forgive and release payment of $832 of the amount owing under the promissory note to MPC.

8.       Litigation

In November 2002, the Company settled a patent
infringement suit with ZOLL Medical Corporation (ZOLL), which it originally initiated in March 2002. The terms of the settlement included the cross licensing of a number of patents between the two parties. Under the terms of the
confidential settlement agreement, the Company received a settlement amount and will be entitled to royalties under a licensing agreement based on ZOLLs AED sales. The Company has recorded the settlement as an offset to legal expense included
in general and administrative expenses in the accompanying consolidated income statement for the year ended December 31, 2002.

December 3, 2002, the Company filed a Complaint in Orange County Superior Court against Medical Research Laboratories, Inc. (MRL) alleging declaratory relief and breach of contract arising out of a July 29, 2002 letter of intent entered
into between the parties. The Company alleged that MRL failed to comply with certain conditions of closing set forth in the letter of intent whereby the Company would acquire all of MRLs stock. MRL filed a cross-complaint, also seeking breach
of contract and declaratory relief arising out of the same letter of intent. On February 25, 2003, the Company filed suit against MRL for patent infringement in the United States District Court for the District of Minnesota.  The Company
alleged that MRLs LifeQuest JumpStart AED infringed the

Companys patented disposable electrode pre-connect technology.  The Company settled both law suits with MRL on June 24, 2003.  Under the terms of the
confidential settlement agreement, the Company received a settlement amount from MRL and MRL received the right to license two of the Companys patents for additional royalties.

In February 2003, the Company announced that it had filed a patent infringement action against Philips Medical Systems North America, Inc., Philips Electronics North
America Corporation and Koninklijke Philips Electronics N.V. (Philips) in the United States District Court for the District of Minnesota. The suit charged that Philips automated external defibrillators sold under the names
HeartStart OnSite Defibrillator and HeartStart Home Defibrillator infringed at least seven of the Companys United States patents. In the same action, the Company also sought a declaration from the Court that the
Companys products do not infringe several of Philips patents.  In June 2003, the Company filed its First Amended Complaint further accusing Philips HeartStart FR2 automated external defibrillator of infringing the
Companys U.S. Patents and removing four of the Philips patents from suit at Philips request.  The Philips HeartStart Home Defibrillator, which was recently cleared by the U.S. Food and Drug Administration
(FDA) for marketing in the United States, is promoted by Philips as including, among other things, pre-connected disposable defibrillation electrodes and daily self-testing of electrodes and battery, features that the suit alleges are
key competitive advantages of the Companys Powerheart and Survivalink AEDs and are covered under the Companys patents.  On June 19, 2003, Philips filed a Complaint against the Company in the United States District Court for the
Western District of Washington.  Philips Complaint alleged patent infringement of ten of Philips U.S. Patents by the Companys Powerheart and Survivalink AEDs.  Five of the asserted patents were already contained in the
Companys Minnesota case against Philips.  The Company has made a motion to dismiss the Washington case as duplicative.  Philips has made a motion in the Minnesota case to have its patents severed from that action.  These motions
are currently pending. At this stage, the Company is unable to predict the outcome of this litigation or its ultimate effect, if any, on its financial condition.

On April 30, 2003, the Company filed a Complaint against Defibtech, LLC for patent infringement in the United States District Court for the District of
Minnesota.  The Complaint alleged that Defibtechs Sentry and Reviver AEDs infringe the Companys patented disposable electrode pre-connect technology. Defibtech answered the Complaint with no counterclaims.  At this stage, the
Company is unable to predict the outcome of this litigation or its ultimate effect, if any, on its financial condition.

In the ordinary
course of business, various lawsuits and claims are filed against the Company. While the outcome of these matters is currently not determinable, management believes that the ultimate resolution of these matters will not have a material adverse
effect on the Companys operations or financial position.

9.       Subsequent Event

On July 31, 2003, the Company announced that they had signed multi-year strategic OEM, distribution and development agreements with GE Medical Systems Information Technologies, under which GE will market the Companys AEDs and CRMs
under the GE name in Europe, Asia, the Middle East and other international markets. Under the agreements, the Company will also develop and manufacture a line of biphasic external defibrillators for exclusive sale by GE on a world-wide basis. The
Company expects to begin shipping the private-label AEDs and CRMs to GE in the fall of 2003.

General

Sudden cardiac arrest (SCA) is the leading cause of death in the United States and Europe.  According to the Centers for Disease Control and
Prevention (the CDC) approximately 450,000 people die annually in the U.S. from sudden cardiac arrest.  Of that number, approximately one-third die from SCA inside a hospital.  For every minute that passes from the onset of
sudden cardiac arrest, a persons survival rate decreases by 10% or more.  Clinical studies have shown that the average survival rate for individuals suffering SCA outside the hospital is

estimated at 5% and for patients suffering SCA in-hospital is about 15% - a rate that has not changed since the 1960s.    The American Heart Association
and other major resuscitation councils around the world have acknowledged that immediate defibrillation therapy is the single most important factor in determining the survival rate of sudden cardiac arrest victims.

Our core technology platform consists of proprietary arrhythmia detection and discrimination software (RHYTHMx®), which is combined with
our proprietary STAR® Biphasic defibrillation hardware and disposable defibrillation electrode technology to create the only fully automatic in-hospital cardioverter defibrillator, the Powerheart® Cardiac Rhythm
Module (the CRM) and an automated public access defibrillator, (the Powerheart® AED) for use in out of hospital settings.  The RHYTHMx technology allows our line of defibrillators to:

| |  | continuously monitor a patients heart rhythms

| |  | instantly and accurately detect the onset of life-threatening arrhythmias, and

| |  | in the case of Powerheart CRM, automatically deliver a potentially life saving defibrillation shock within seconds of the onset of SCA and with no human intervention, or in the case of our
Powerheart AED product, advise the operator to deliver the therapy.

Our initial product, the Powerheart
AECD®, was introduced into the United States in February 2000.  This first generation product was replaced by our second-generation device, the Powerheart CRM, which received market clearance from the U.S. Food and Drug
Administration (FDA) in February 2002. We began shipping the CRM in limited quantities in March 2002.  The Powerheart CRM is approximately 25% of the size of the original Powerheart and costs approximately 60% less to
manufacture.  Based on the safety and efficacy of the RHYTHMx technology, the Powerheart CRM is the only hospital bedside monitor defibrillator cleared by the FDA to be prophylactically attached to hospital patients and provide automatic
defibrillation without human intervention.   The Powerheart CRM is a compact, portable, fully-automatic defibrillator, which utilizes a proprietary and patented biphasic defibrillation waveform and is designed to provide complete cardiac
rhythm management capabilities, including fully automatic, semi-automatic and manual defibrillation therapy modes and external pacing and function as a stand-alone defibrillator, or in conjunction with existing third party patient monitoring
systems.  We believe that the Powerheart CRM can create a new standard of care for hospitalized cardiac patients and significantly increase the survival rate of patients suffering sudden cardiac arrest.

In September 2001, we acquired Survivalink Corporation, a Minneapolis, Minnesota based developer, manufacturer and marketer of automated public access defibrillators
(AEDs) and related accessories and products.  These devices are portable, emergency defibrillators intended for use by minimally trained rescuers in the treatment of SCA in a wide variety of settings.   The
Survivalink® AED is distinct from the competition and features one-button operation and pre-connected, interchangeable electrodes and RescueReady® self-testing capabilities that ensure that the battery, circuitry and
electrodes are functioning properly.

In early 2002, we successfully integrated our RHYTHMx algorithm technology into the
Survivalink AED, and made other improvements in the device.  Among other things, the Powerheart AED is now capable of being attached to people exhibiting symptoms of cardiac arrest and providing continuous monitoring of patients
post-resuscitation.  In February 2002, we received FDA clearance to market and began shipping the Powerheart AED.

While the
Powerheart AED currently accounts for the overwhelming majority of our AED sales, we plan to continue to manufacture and make available the original Survivalink AED to customers for as long as there is any material demand.

In December 2001, we acquired approximately 95% of the outstanding shares of Artema Medical AB, a Stockholm, Sweden based developer and
manufacturer of emergency defibrillators and patient monitoring equipment, which are sold via distributors exclusively outside the U.S.  In addition to broadening our product line, the acquisition increased our international distribution
channel.  Effective April 1, 2003, we acquired the remaining  minority interest in Artema for $1,299 in cash.

##### Table of Contents

We own 70 issued patents and have 12 patent applications pending relating to our core defibrillation and software
technology, wearable defibrillation technology, disposable defibrillation electrode pad technology and to the AED technology originally developed by Survivalink.  We believe strongly in the value of our intellectual property and intend to
continue to file additional patent applications relating to our technology.

We are highly focused on increasing revenue and gaining
additional market share in the fast growing AED or public access defibrillation market in our domestic U.S. market as well as other countries around the world. We estimate that we currently hold approximately 25% of the worldwide market for AEDs,
which is projected to grow at a rate of 30% per year according to the market analysis published by Frost & Sullivan in 2000.  They also estimate that the worldwide market for AEDs will expand to over 250,000 units a year by 2006, accounting
for over $650 million in annual market revenue.

Our multi-faceted growth strategy includes sales and marketing initiatives
designed to take advantage of fast growing segments such as the U.S. corporate workplace market segment, municipal public access programs, schools, law enforcement, fire departments and government and continued increases in our direct and in-direct
distribution channels. Our growth strategy is focused on offering what we believe is the easiest to use and most technologically sophisticated line of AEDs on the market.  We are currently marketing the Survivalink and Powerheart AEDs in the
U.S. through our direct sales force and over 75 independent distributors.

Since the acquisition of Survivalink in September 2001, we
have tripled the size of our direct sales force. At the end of June 2003, there were 50 direct sales persons and 7 sales managers in the U.S. and 8 employee sales managers supporting international distributors in overseas markets. 
Internationally, we are selling our complete line of products, including our AEDs, through independent medical device distributors on a country-by-country basis with over 45 distributors selling the Companys products in over 50 countries. We
intend to establish direct sales operations in certain markets, and as part of this strategy, we acquired Lifetec Medical Limited, our U.K. distributor in May 2003.

Our strategy for the hospital based Powerheart CRM is centered on building an installed base of devices in order to maximize the potential recurring revenue
associated from the sale of our proprietary, single use, disposable defibrillator electrode pads.  The Powerheart CRM is designed to utilize these defibrillator electrodes, which for sanitary, safety and performance reasons, must be changed
once every 24 hours.  Our defibrillator electrodes feature proprietary smart chip technology, designed to ensure that only our electrodes will be used with the Powerheart CRM.  In April 2001, we began direct marketing
activities to hospitals in the United States, and are currently marketing the Powerheart CRM through a 3 person direct sales force, supported by 6 clinical specialists.  We offer the Powerheart CRM to hospitals on a traditional outright
purchase basis as well as on a no-cap program, which allows the customer to adopt the technology without up-front capital expenditure.  Under this model, we market the Powerheart CRM to U.S. hospitals directly, and agree to place
units in a customers facility, while retaining ownership of the unit, with no upfront capital equipment charge, in exchange for an agreement to purchase a specific number of our proprietary, disposable defibrillation electrodes monthly or
quarterly.  We believe this model may increase the rate of adoption of our Powerheart CRM technology by addressing the capital budget constraints many U.S. hospitals face and will ultimately result in higher levels of recurring revenue from
disposable electrodes.  We have also entered into several distribution agreements with regional medical distributors for the sale of the CRM product line.

Internationally, the Powerheart CRM is sold to end users via distributors.  We also intend to enter into strategic alliances or OEM relationships with third
party patient monitoring equipment manufacturers to increase the adoption rate for our in-hospital technology.

Results of Operations

Quarter Ended June 30, 2003 Compared to the Quarter Ended June 30, 2002

Revenue for the quarter ended June
30, 2003 increased $1,686 or 13.1% to $14,527, compared to $12,841 for the quarter ended June 30, 2002. This increase is primarily attributable to a 43.1% increase in sales of AED and related accessories to $13,276 this quarter as compared to $9,279
in the second quarter of 2002.  This increase in AED revenue was partially offset by a 79% decrease in sales of emergency defibrillators and patient monitors to

##### Table of Contents

$665 this quarter from $3,174 last quarter.  This decrease resulted from lower patient monitoring sales to the Middle East due to the war in Iraq, and the planned phase
out of certain low margin, legacy Artema product lines.

Cost of goods sold for the quarter ended June 30, 2003 was $6,221 compared to
$6,667 for the quarter ended June 30, 2002.  Gross margins, as a percentage of revenue, improved to 57.2% in the second quarter of 2003 compared to 48.1% in the second quarter of 2002. The improvement in gross margins is primarily the result of
an increase of higher margin AED sales as a percentage of total revenue. In addition, the gross margin on the Diascope patient monitor has increased year over year due to reductions in manufacturing costs.

Sales and marketing expenses increased $94 to $3,946 or 27.2% of revenue for the quarter ended June 30, 2003, compared to $3,852 or 30.0% of revenue in the quarter
ended June 30, 2002. The absolute dollar increase in sales and marketing expense is primarily attributable to higher levels of direct sales costs, including salaries, fringe benefits, commissions and travel costs associated with the expansion of our
direct AED sales force which grew from approximately 45 to 56 representatives year over year.  The decrease in sales and marketing costs as a percentage of revenue reflects the operating leverage we are beginning to realize.

Research and development expenses decreased $224 or 13.9% to $1,393 in the second quarter of 2003, compared to $1,617 or 12.6% of revenue for the quarter
ended June 30, 2002. This decrease is primarily attributable to a reduction in headcount and associated costs related to the completion of the Powerheart CRM project in 2002.

General and administrative expenses for the quarter ended June 30, 2003 were $3,207, which represented an increase of $133 or 4.3% over the $3,074 in the quarter
ended June 30, 2002. This increase over the prior year was primarily comprised of the remaining one time expenses of $187 associated with the relocation of our corporate facilities and centralization of certain operations.

Amortization of intangibles was $381 for the quarter ended June 30, 2003, a decrease of $176 or 31.6% from the $557 for the quarter ended June 30, 2002. This
decrease resulted from certain identifiable intangible assets becoming fully amortized.

Net interest and other non-operating expense for
the quarter ended June 30, 2003 was $1,483 compared to  $821 for the same period in 2002. This increase was primarily a result of higher interest expense and amortization of the debt discount and debt issuance costs associated with the Senior
Debt issued in May 2002.

Six Months ended June 30, 2003 Compared to the Six Months Ended June 30, 2002

Revenue for the six months ended June 30, 2003 increased $6,349 or 28.8% to $28,551 as compared to $22,202 for the six months ended June 30, 2002.  The increase
in net sales was attributable to a 56.4% increase in the sales of AEDs and related accessories to $25,690 in this period as compared to $16,430 in the prior year period.  This increase in AED revenue was offset by a 58% reduction in sales
of emergency defibrillators and patient monitors primarily resulting from the planned phase out of certain low margin, legacy Artema product lines.

Cost of goods sold for the six months ended June 30, 2003 was $12,310 as compared to $11,557 for the six months ended June 30, 2002.  Gross margins as a
percentage of revenue improved to 56.9% from 47.9% for the comparable period in 2002.  The improvement in gross margins was primarily a result of the shift in product mix to the higher margin AEDs and accessories which accounted for 90% of
total revenue this period compared to 74% in the prior year.

Sales and marketing expense for the six months ended June 30, 2003
increased $897 from $8,363, or 29.3% of sales, this period as compared to $7,466, or 33.6% of sales, for the same six month period in 2002.  The increase in absolute dollars is primarily attributable to the expenses associated with an increase
in our direct sales organization. The decrease in sales and marketing costs as a percentage of revenue reflects the operating leverage we are beginning to realize.

Research and development expenses for the six months ended June 30, 2003 decreased $675 to $2,495, or 8.7% of
sales, as compared to $3,170, or 14.3% of sales, for the comparable period in 2002. This decrease is primarily attributable to a reduction in headcount and associated costs related to the completion of the Powerheart CRM project in 2002.

General and administrative expenses for the six months ended June 30, 2003 increased $886 to $6,414, or 22.5% of sales, as compared to $5,528, or
23.7% of sales for the comparable period in 2002.  The increase was primarily comprised of $718 in non-recurring charges related to our facility relocation and centralization of certain operations, with the balance of the increase made up of a
variety of other general corporate expenditures associated with supporting the growth of the company.

Amortization of intangibles
decreased $228 or 21.6% to $830 for the six months ended June 30, 2002 from $1,058 for the comparable period in 2002.  This decrease resulted from certain identifiable intangible assets becoming fully amortized.

Net interest and other non-operating expense increased $1,404 to $2,884 for the six months ended June 30, 2003 compared to $1,480 for the comparable period in
2002.  This increase was primarily a result of higher interest expense and amortization of the debt discount and debt issuance costs associated with the Senior Debt issued in May 2002.

Liquidity and Capital Resources

At June 30, 2003, we had cash and cash equivalents of $9,894 and working
capital of $19,550 as compared to cash and cash equivalents of $15,598 and working capital of $19,177 at December 31, 2002. At June 30, 2003 our current days sales outstanding on accounts receivable was approximately 88 days. From inception, our
sources of funding for operations and mergers and acquisition activity were derived from issuance of debt and equity securities.  In May 2002, we entered into a Senior Note and Warrant Purchase Agreement with investors pursuant to which the
investors loaned $50,000 to us.  We in turn repaid the $26,468, plus accrued interest, in senior promissory notes relating to the Survivalink acquisition.

From inception through June 30, 2003, we incurred losses of $97,707. Recovery of our assets is dependent upon future events, the outcome of which is indeterminable.
Additionally, transition to profitable operations is dependent upon achieving a level of revenues adequate to support our cost structure. The accompanying financial statements have been prepared assuming that the Company will continue as a going
concern.

We believe that our current cash balances, combined with net cash that we expect to generate from operations, will sustain our
ongoing operations for at least twelve months. In the event that we require additional cash to support our operations during the next twelve months, we will attempt to raise the required capital through either debt or equity arrangements. We cannot
provide any assurance that the required capital will be available on acceptable terms, if at all, or that any financing activity will not be dilutive to our current stockholders. If we are not able to raise additional funds, we may be required to
significantly curtail our operations and this would have an adverse effect on our financial position, results of operations and cash flows.

We had no material commitments for capital expenditures as of June 30, 2003.

Income Taxes

As of December 31, 2002, the Company has research and experimentation credit carry forwards for federal and state purposes of approximately $2,613 and
$1,123 respectively. These credits begin to expire in 2006 for federal and state purposes. The Company also has approximately $124,716 and $72,742 of federal and state net operating loss carry forwards which will begin to expire in 2004 and 2006,
respectively. The utilization of net operating loss and tax credit carry forwards may be significantly and materially limited under the provisions of Internal Revenue Code Sections 382 and 1503 and similar state provisions.

Critical Accounting Policies

Our discussion and
analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these
financial statements requires us to make estimates and judgments that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenue
and expenses for each period.

The following represents a summary of our critical accounting policies, defined as those policies that we
believe are: (a) the most important to the portrayal of our financial condition and results of operations, and (b) that require our most difficult, subjective or complex judgments, often as a result of the need to make estimates about the
effects of matters that are inherently uncertain.

Valuation of Accounts Receivable

We maintain an allowance for uncollectible accounts receivable to estimate the risk of extending credit to customers. The allowance is estimated based on customer
compliance with credit terms, the financial condition of the customer and collection history, where applicable. Additional allowances could be required if the financial condition of our customers were to be impaired beyond our estimates.

Valuation of Inventory

Inventory is valued at the lower of cost (estimated using the first-in, first-out method) or market. We periodically evaluate the carrying value of inventories and
maintain an allowance for obsolescence to adjust the carrying value, as necessary, to the lower of cost or market. The allowance is based on physical and technical functionality as well as other factors affecting the recoverability of the asset
through future sales. Unfavorable changes in estimates of obsolete inventory would result in an increase in the allowance and a decrease in gross profit.

Goodwill and Other Intangibles

In
accordance with SFAS No. 142, Goodwill and Other Intangible Assets, which became effective January 1, 2002, goodwill and other intangible assets with indeterminate lives are no longer subject to amortization but are tested for impairment
annually or whenever events or changes in circumstances indicate that the asset might be impaired. Other intangible assets with finite lives continue to be subject to amortization, and any impairment is determined in accordance with SFAS No. 144,
Accounting for the Impairment or Disposal of Long-Lived Assets.

Should an impairment in goodwill be determined, it could
result in a material charge to operations.

Valuation of Long-Lived Assets

In accordance with SFAS No. 144, long-lived assets and intangible assets with determinate lives are reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be recoverable. The Company evaluates potential impairment by comparing the carrying amount of the asset with the estimated undiscounted future cash flows associated with the use of
the asset and its eventual disposition. Should the review indicate that the asset is not recoverable, the Companys carrying value of the asset would be reduced to its estimated fair value, which is generally measured by future discounted cash
flows. In our estimate, no provision for impairment is currently required on any of our long-lived assets.

Revenue Recognition

We record revenue in accordance with SEC Staff Accounting Bulletin No. 101, Revenue Recognition in Financial Statements (SAB
101), as amended. Product sales are recognized when there is persuasive evidence of an arrangement which states a fixed and determinable price and terms, delivery of the product has occurred in accordance with the terms of the sale, and
collectibility of the sale is reasonably assured. Some of the Companys customers are distributors which sell goods to third party end users. The Company is not contractually obligated to

20



---

##### Table of Contents

repurchase any inventory from distributors or end user customers. License fees are generally deferred and recognized systematically over the term of the license agreement.

We record sales when we have received a valid customer purchase order for product at a stated price, the customers credit is
approved and we have shipped the product to the customer.

Product Warranty

Products sold are generally covered by a warranty against defects in material and workmanship for a period of one to five years. We accrue a warranty reserve to
estimate the risk of incurring costs to provide warranty services. The accrual is based on our historical experience and our expectation of future conditions. An increase in warranty claims or in the costs associated with servicing those claims
would result in an increase in the accrual and a decrease in gross profit.

Discontinued Operations

SFAS No. 144 establishes accounting and reporting standards requiring that long-lived assets to be disposed of be reported as discontinued operations if
management has committed to a plan to dispose of the assets under usual and customary terms within one year of establishing the plan.  The acquisition and initiation of disposal of our MCS gas business occurred prior to the effective date of
SFAS No. 144, therefore, we have followed the guidance of EITF 90-6, Accounting for Certain Events Not Addressed in Issue No. 87-11 Related To an Acquired Operating Unit To Be Sold for the period subsequent to the initial one-year period and
classified operations of this business as discontinued operations.

Litigation and Others Contingencies

We regularly evaluate our exposure to threatened or pending litigation and other business contingencies. Because of the uncertainties related to the
amount of loss from litigation and other business contingencies, the recording of losses relating to such exposures requires significant judgment about the potential range of outcomes. As additional information about current or future litigation or
contingencies becomes available, we will assess whether such information warrants the recording of additional expense relating to contingencies. To be recorded as expense, a loss contingency must generally be both probable and measurable. If a loss
contingency is material but is not both probable and estimable, we will disclose it in notes to the financial statements.

Recent Accounting Pronouncements

In June 2002, the Financial Accounting Standards Board (FASB) issued SFAS No. 146 (SFAS No. 146), Accounting for Exit or Disposal Activities.
SFAS No. 146 is effective for exit or disposal activities that are initiated after December 31, 2002. SFAS No. 146 addresses significant issues regarding the recognition, measurement, and reporting of costs that are associated with exit and disposal
activities, including restructuring activities that were previously accounted for pursuant to the guidance that the Emerging Issues Task Force (EITF) has set forth in EITF Issue No. 94-3, Liability Recognition for Certain Employee Termination
Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring). The scope of SFAS No. 146 also includes (1) costs related to terminating a contract that is not a capital lease, and (2) termination
benefits that employees who are involuntarily terminated receive under the terms of a one-time benefit arrangement that is not an ongoing benefit arrangement or an individual deferred-compensation contract. Our adoption of SFAS No. 146 had an impact
on our accounting for our corporate restructuring and relocation (see Note 6 of the consolidated financial statements).

In
November 2002, the FASB issued Interpretation No. 45 (FIN 45), Guarantors Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees Of Indebtedness Of Others, an Interpretation of FASB Statements No. 5, 57, and
107 and Rescission of FASB Interpretation No. 34. FIN 45 relates to the accounting for and disclosure of guarantees and addresses (1) an obligation to stand ready to perform over the term

21



---

##### Table of Contents

of the guarantee in the event that the specified triggering events or conditions occur and (2) a contingent obligation to make future payments if those triggering events or
conditions occur. FIN 45 excludes certain types of guarantees from its initial recognition and measurement, including guarantees accounted for as derivative instruments and hedging activities, guarantees relating to performance of non-financial
assets that are owned by the guaranteed party (e.g., product warranties), guarantees issued in a business combination that represents contingent consideration, and others. They are subject to its disclosure requirements. The disclosure requirements
are effective for financial statements of interim and annual periods ending after December 15, 2002. The initial recognition and initial measurement provisions should be applied only on a prospective basis to guarantees issued or modified after
December 31, 2002. The guarantors previous accounting for guarantees issued prior to the initial application date of FIN 45 should not be revised or restated to reflect the effect of the new recognition and measurement provisions. We do not
believe that the adoption of FIN 45 will have a material impact on our consolidated financial statements.

EITF Issue No. 00-21
(Issue 00-21), Revenue Arrangements with Multiple Deliverables addresses the accounting for multiple element revenue arrangements, which involve more than one deliverable or unit of accounting in circumstances, where the
delivery of those units takes place in different accounting periods. Issue 00-21 requires disclosure of the accounting policy for revenue recognition of multiple element revenue arrangements and the nature and description of such arrangements. It
will be effective for revenue arrangements entered into in fiscal periods beginning after June 15, 2003. We do not expect that the adoption of Issue 00-21 will have a significant impact on our consolidated financial statements.

In May 2003, the FASB issued Statement of Financial Accounting Standards No. 150, Accounting For Certain Financial Instruments with Characteristics of both Liabilities and Equity
(SFAS 150). SFAS 150 establishes standards for how an issuer classifies and measures in its statement
of financial position certain financial instruments with characteristics of both liabilities and equity. It requires that an issuer classify a financial instrument that is within its scope as a liability (or an asset in some circumstances) because
that financial instrument embodies an obligation of the issuer. SFAS 150 is effective for financial instruments entered into or modified after May 31, 2003, and otherwise shall be effective at the beginning of the first interim period beginning
after June 15, 2003. We do not believe that the adoption of SFAS 150 will have a material impact on our consolidated financial statements.

|ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|------- | ----------------------------------------------------------

Interest Rate and Market Risk.    We do not use derivative financial instruments in our investment portfolio. We are averse to principal
loss and try to ensure the safety and preservation of our invested funds by limiting default risk, market risk, and reinvestment risk. We attempt to mitigate default risk by investing in only the safest and highest credit quality securities. At June
30, 2003, we invested our available cash in money market securities of high credit quality financial institutions with original maturities of 90 days or less.

Interest expense on our existing long-term debt commitments is based on a fixed interest rate and therefore it is unaffected by fluctuations in interest rates.

Foreign Currency Exchange Rate Risk.    The international sales of the companys products, are made
through the companys international sales offices in Copenhagen in foreign currencies, and thus may be adversely affected by fluctuations in currency exchange rates. Additionally, fluctuations in currency exchange rates may adversely affect
foreign demand for the companys products by increasing the price of the companys products in the currency of the countries in which the products are sold. Our operations outside of the United States are maintained in their local
currency. All assets and liabilities of our international subsidiaries are translated to U.S. dollars at period-end exchange rates and income and expenses are translated using monthly average exchange rates.  Translation adjustments arising
from the use of differing exchange rates are included in accumulated other comprehensive income in stockholders equity. Gains and losses on foreign currency transactions are included in operations and were not material in any period.

|ITEM 4. | CONTROLS AND PROCEDURES
|------- | -----------------------

Evaluation of disclosure controls and procedures.We maintain disclosure controls and procedures that are designed to ensure that information required to
be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms, and that such information is accumulated and communicated to our management including our
Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure based closely on the definition of

22

##### Table of Contents

disclosure controls and procedures in Rule 13a-15(e) and 15(d)-15(e).  In designing and evaluating the disclosure controls and procedures, we recognized that
any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit
relationship of possible controls and procedures.

As of the end of the reporting period, we carried out an evaluation, under the
supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures.  Based on that evaluation, our Chief Executive Officer
and Chief Financial Officer have concluded that as of the date of the evaluation, our disclosure controls and procedures were adequate to timely alert them of material information to be included in our periodic SEC filings.

Changes in internal controls.There were no significant changes in our internal controls, or to our knowledge, in other factors that could
significantly affect our disclosure controls and procedures subsequent to the date of our most recent evaluation.

CARDIAC SCIENCE, INC.

PART II.    OTHER INFORMATION

Item 1.     Legal Proceedings

On December 3, 2002, the Company filed a Complaint in Orange County Superior Court against Medical Research Laboratories, Inc.
(MRL) alleging declaratory relief and breach of contract arising out of a July 29, 2002 letter of intent entered into between the parties. The Company alleged that MRL failed to comply with certain conditions of closing set forth in the
letter of intent whereby the Company would acquire all of MRLs stock. MRL filed a cross-complaint, also seeking breach of contract and declaratory relief arising out of the same letter of intent. On February 25, 2003, the Company filed suit
against MRL for patent infringement in the United States District Court for the District of Minnesota.  The Company alleged that MRLs LifeQuest JumpStart AED infringed the Companys patented disposable electrode pre-connect
technology.  The Company settled both law suits with MRL on June 24, 2003.  Under the terms of the confidential settlement agreement, the Company received a settlement amount from MRL and MRL received the right to license two of the
Companys patents for additional royalties.

In February 2003, it was announced that we had filed
a patent infringement action against Philips Medical Systems North America, Inc., Philips Electronics North America Corporation and Koninklijke Philips Electronics N.V. (Philips) in the United States District Court for the District of
Minnesota. The suit charged that Philips automated external defibrillators sold under the names HeartStart OnSite Defibrillator and HeartStart Home Defibrillator infringed at least seven of our United States patents. In
the same action, we also sought a declaration from the Court that our products do not infringe several of Philips patents.  In June 2003, we filed our First Amended Complaint further accusing Philips HeartStart FR2
automated external defibrillator of infringing our U.S. Patents and removing four of the Philips patents from suit at Philips request.  The Philips HeartStart Home Defibrillator, which was recently cleared by the U.S.
Food and Drug Administration (FDA) for marketing in the United States, is promoted by Philips as including, among other things, pre-connected disposable defibrillation electrodes and daily self-testing of electrodes and battery, features
that the suit alleges are key competitive advantages of our Powerheart and Survivalink AEDs and are covered under our patents.  On June 19, 2003, Philips filed a Complaint against us in the United States District Court for the Western District
of Washington.  Philips Complaint alleged patent infringement of ten of Philips U.S. Patents by our Powerheart and Survivalink AEDs.  Five of the asserted patents were already contained in our Minnesota case against
Philips.  We have made a motion to dismiss the Washington case as duplicative.  Philips has made a motion in the Minnesota case to have its patents severed from that action.  These motions are currently pending. At this stage, we are
unable to predict the outcome of this litigation or its ultimate effect, if any, on our financial condition.

On April 30, 2003,  we filed a Complaint against Defibtech, LLC for patent infringement in the United States District
Court for the District of Minnesota.  The Complaint alleged that Defibtechs Sentry and Reviver AEDs infringe our patented disposable electrode pre-connect technology. Defibtech answered the Complaint with no counterclaims.  At this
stage, we are unable to predict the outcome of this litigation or its ultimate effect, if any, on our financial condition.

In the ordinary course of business, various lawsuits and claims are filed against us. While the outcome of these matters is
currently not determinable, we believe that the ultimate resolution of these matters will not have a material adverse effect on our operations or financial position.
