IRIS INTERNATIONAL, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited  dollars in thousands except per share amounts)

1. Nature of Business

IRIS International, Inc. was incorporated in California in 1979. We design, develop, manufacture and
market in vitro diagnostic (IVD) products, including IVD imaging systems based on patented and proprietary neural network-based Automated Particle Recognition (APR) software to enable high-speed digital processing to classify and
display images and describe the morphology, of microscopic particles, molecular diagnostics assays based in our Nucleic Acid Detection Immuno-Assay (NADIA) technology, as well as special purpose centrifuges and other small instruments for automating
microscopic procedures performed in clinical laboratories.

2. Interim Financial Reporting

Basis of Presentation The financial statements have been prepared in accordance with the instructions to Form 10-Q under the Securities
Exchange Act of 1934, as amended, and do not include all of the information and note disclosures required by accounting principles generally accepted in the United States (GAAP). These financial statements should be read in conjunction
with the Consolidated Financial Statements and accompanying notes contained in the Companys Annual Report on Form 10-K for the year ended December 31, 2006.

The Consolidated Financial Statements included herein are unaudited, but in the opinion of management, such financial statements include all adjustments,
consisting only of normal recurring adjustments, necessary to summarize fairly the Companys financial position and results of operations for the interim period. The results reported in these Consolidated Financial Statements should not be
taken as indicative of results that may be expected for the entire year.

Use of Estimates The preparation of financial
statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The significant estimates in the preparation of the consolidated financial statements relate to the
assessment of the carrying value of accounts receivables, inventories, purchased intangibles, estimated provisions for warranty costs and deferred tax assets. Actual results could differ materially from those estimates.

Earnings Per Share Basic earnings per share are computed by dividing net income or loss by the weighted average number of common shares
outstanding. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares and common stock equivalents outstanding, calculated on the treasury stock method for options and warrants. The weighted
average number of outstanding antidilutive common stock options and warrants excluded from the computation of diluted net income per common share for the three and six month periods ended June 30, 2007 were 443,000 and 462,000. During the
prior year periods, we incurred a loss, accordingly all outstanding options and warrants were excluded from the computation because they were anti-dilutive. A reconciliation of the shares used in the basic and diluted earnings per common share is as
follows:

3. Acquisition

On April 3, 2006 we acquired all the stock of Leucadia Technologies, Inc., a development stage molecular diagnostics company pursuant to the merger of Leucadia into our wholly-owned subsidiary renamed Iris
Molecular Diagnostics (IMD). With this acquisition we acquired significant core technology for an ultra-sensitive immunoassay process and novel in-vitro separation and concentration process as well as in-process research and development
for bacteria and cancer detection applications.

Pursuant to the acquisition agreement we paid $3.3 million of cash, 272,375 shares of IRIS
common stock, valued at $4.2 million, deferred stock units for 51,879 shares of IRIS common stock valued at $800,000 and $230,000 of transaction fees. The IRIS common stock and deferred stock units were valued based on the average closing market
price of IRIS common stock a few days before and a few days following the acquisition. In addition, we will issue up to 108,950 shares of IRIS common stock and deferred stock units for 20,752 shares of IRIS common stock as earn-out consideration if
certain regulatory and sales milestones are achieved.

The acquisition was accounted for as a purchase with the allocation, based on fair
value, as follows:

5. Bank Loan Agreement

We have a credit facility with a commercial bank. The credit facility consists of a $6.5 million revolving line of credit for working capital and a $10.0 million line of credit for acquisitions and product
opportunities. Borrowings under the revolving line of credit are limited to a percentage of eligible receivables and inventory. The entire credit facility has variable interest rates, which will change from time to time based on changes to either
the LIBOR rate or the lenders prime rate.

As of June 30, 2007 and December 31, 2006, there were no outstanding borrowings under
the credit facility. We are however, subject to certain financial covenants under the credit facility with the bank and as of June 30, 2007, we were in compliance with such covenants.

6. Income Taxes

On a quarterly basis, we estimate
what our effective tax rate will be for the full fiscal year and record a quarterly income tax provision based on the anticipated rate. As the year progresses, we refine our estimate based on the facts and circumstances by each tax jurisdiction. The
effective tax rates for the three and six months ended June 30, 2007 were 30% and 35%.

We adopted the provisions of Financial
Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes-an Interpretation of FASB Statement 109 (FIN 48), on January 1, 2007. Our condensed consolidated financial statements for 2007
reflect the impact of FIN 48, but the condensed consolidated financial statements for 2006 have not been restated to reflect, and do not include, the impact of FIN 48.

As a result of the initial adoption of FIN 48, we recognized a $547,000 reduction in our deferred tax benefit relating to federal and California tax credits for which we could not conclude that it is more likely than
not that such tax credits will be sustainable on audit by the respective taxing authorities. As a result we reduced the deferred tax asset by $547,000 and recorded a charge to retained earnings as of January 1, 2007, by a like amount.

We will recognize potential interest and penalties related to income tax positions as a component of the provision for income taxes on the
consolidated statements of income in any futures periods in which we must record a liability. Since we have not recorded a liability at June 30, 2007, there would be no impact on our effective tax rate. We do not anticipate that total
unrecognized tax benefits will significantly change during the next twelve months. We are no longer subject to federal, state, or foreign income tax examinations for years prior to 2003.

7. Stock-Based Compensation

Effective January 1, 2006, we adopted the provisions of Statement
of Financial Accounting Standards (SFAS) No. 123R, Share-Based Payment, which requires compensation costs related to share-based transactions, including employee stock options, to be recognized in the financial
statements based on fair value. Share-based compensation expense for the three months and six months ended June 30, 2007 and 2006 includes incremental share-based compensation expense as follows:

The aggregate intrinsic value in the table above represents the total pretax intrinsic value (the
difference between our closing stock price on June 30, 2007 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders, had all option holders exercised their options on
June 30, 2007. Total intrinsic value of options exercised for the six months ended June 30, 2007 amounted to $1,404,000. As of June 30, 2007, total unrecognized stock-based compensation expense related to nonvested stock options was
$2.6 million which is expected to be recognized over the remaining weighted average period of 3.7 years.

Restricted Shares

We began awarding restricted share units in 2006. Restricted shares currently vest 25% after one
year and 61/4% quarterly thereafter. Unvested restricted shares are forfeited if the recipients employment
terminates for any reason other than death, disability, or special circumstances as determined by the Compensation Committee of the Board. Restricted shares activity during the six months ended June 30, 2007 is as follows:

Fair value of our restricted shares is based on our closing stock price on the date of grant. As
of June 30, 2007, total unrecognized stock-based compensation expense related to non vested restricted share grants was $1.7 million which is expected to be recognized over the remaining weighted average period of approximately 2.9 years.

The Compensation Committee of the Board of Directors determines the exercise price of options. Payment of the exercise price may be made
either in cash or with shares of common stock that have been held at least six months. The options generally vest over either three or four years and expire either five or ten years from the date of grant. The fair value of each option grant is
estimated on the date of the grant using the Black-Scholes option pricing model with the following weighted average assumptions:

The expected volatilities are based on the historical volatility of our stock. The observations are made
on a weekly basis. The expected terms of the stock options are based on the average vesting period on a basis consistent with the historical experience for similar option grants. The risk-free rate is consistent with the expected terms of the stock
options and based on the U.S. Treasury yield curve in effect at the time of grant.

A summary of our non-vested stock options during the
six months ended June 30, 2007 is presented below:

8. Capital Stock  Warrants

At June 30, 2007, there were outstanding and exercisable warrants to purchase 74,300 shares at a price of $7.80 per share.

9. Contingencies

Litigation

From time to time, we are party to certain litigation arising in the normal course of business. Management believes that the resolution of such matters
will not have a material adverse effect on our financial position, results of operations or cash flows.

Guarantees

We enter into indemnification provisions under (i) agreements with other companies in the ordinary course of business, typically with business
partners, contractors, customers and landlords, and (ii) agreements with investors. Under such provisions we generally indemnify and hold harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of our
activities or, in some cases, as a result of the indemnified partys activities under the agreement. Indemnification provisions often include indemnifications relating to representations made by us with regard to intellectual property rights.
Such indemnification provisions generally survive termination of the underlying agreement. In addition, in some cases, we agree to reimburse employees for certain expenses and to provide salary continuation. The maximum potential amount of future
payments we could be required to make under these indemnification provisions is unlimited. To date, we have not incurred any material costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, we believe the
estimated fair value of these agreements is minimal. Accordingly, we have no recorded liabilities for these agreements as of June 30, 2007.

10.
Segments and Geographic Information

Our operations are organized on the basis of products and related services and under SFAS
No. 131, we operate in two segments: (1) IVD and (2) sample processing.

The IVD segment designs, develops, manufactures,
markets and distributes IVD systems based on patented and proprietary technology for automating microscopic procedures for urinalysis. The segment also provides ongoing sales of supplies and services necessary for the operation of installed
urinalysis workstations. In the United States, these products are sold and serviced primarily through a direct sales and service force. Internationally, these products, with the exception of France, are sold and serviced through distributors. The
segment also includes the operations of IMD.

The sample processing segment designs, develops, manufactures and markets a variety of bench
top centrifuges, small instruments and supplies. These products are used primarily for manual specimen preparation and dedicated applications in coagulation, cytology, hematology and urinalysis. These products are sold worldwide through
distributors.

The accounting policies of the segments are the same as those described in the Summary of
Significant Accounting Policies. We evaluate the performance of our segments and allocate resources to them based on earnings before income taxes, excluding corporate charges (Segment Profit).

The tables below present information about reported segments for the three and six months ended June 30, 2007 and 2006:

Overview

IRIS International, Inc. consists of units in two business segments as determined in
accordance with SFAS 131. Our largest unit, Iris Diagnostics Division, designs, manufactures and markets in vitro diagnostics (IVD) systems, consumables and supplies for urinalysis. Our Sample Processing division markets small centrifuges and other
processing equipment and accessories for rapid specimen processing. With the acquisition of Leucadia Technologies and the creation of Iris Molecular Diagnostics in April 2006, we acquired significant core technology for an ultra-sensitive
immunoassay process and novel in-vitro separation and concentration process as well as in-process research and development for bacteria and cancer detection applications.

We generate revenues primarily from: sales of IVD instruments, IVD consumables and service and sample processing instruments and supplies. Revenues from IVD instruments include sales of urine microscopy and chemistry
analyzers manufactured by us and urine chemistry analyzers sourced from a Japanese manufacturer. We sell the urine microscopy analyzers and the iChem 100; our new semi-automated chemistry analyzer introduced in the third quarter of 2006 on a global
basis and distribute the other chemistry analyzers domestically only. Consumables include products such as chemical reagents and urine test strips. Service revenues are derived primarily from annual service contracts purchased by our domestic
customers after the initial year of sale, which is covered by product warranties and spare parts from international customers. Once the analyzers are installed, we generate recurring revenue from sales of consumables. Consumable and service revenue
will continue to expand as the installed base of related instruments increases. Revenue is also generated from sales of sample processing instruments and related supplies, which primarily consists of centrifuge systems, DNA processing workstations
and blood analysis products.

Domestic sales of our automated urinalysis systems are direct to the customer through our sales force.
International sales, with the exception of France, are through independent distributors. Sales in France are direct to end use customers. International sales represented 32% of consolidated revenues during the first half of 2007 as compared to 31%
during the first half of 2006. Since the launch of our iQ200 product line, we have increased our sales efforts in the international marketplace, with the ultimate goal of balancing our urinalysis business between domestic and international markets.
Our Sample Processing products are sold worldwide through distributors.

We make significant investments in research and development for
new products and enhancements to existing products. We internally fund research and development programs. During the second quarter of 2007 we closed the operations of our Advanced Digital Imaging Research subsidiary (ADIR), whose costs
had previously been substantially covered by government sponsored grants. Under government guidelines under the Small Business Administration (SBA), ADIR no longer qualifies for government grant funding previously provided to ADIR. While
the closing of ADIR resulted in one-time charges of approximately $163,000, future period expense should decrease slightly as we will no longer subsidize the salaries and related overhead of this subsidiary.

In addition to the suspension of government funding, the 3D facial recognition technology which ADIR had been developing would have taken at least
another two years to develop a commercial product capable of screening individuals at airports and other security checkpoints. Further, the present market for 3D facial recognition is practically non-existent and it would likely take years to
develop a commercially viable product. Therefore, as this product development initiative was outside of our core healthcare business it was the opinion of management that it was not in the best interest of our shareholders to continue these efforts.

Application of Critical Accounting Policies and Use of Estimates

A description of our critical accounting policies that represent the more significant judgments and estimates used in the preparation of our financial
statements was provided in the Managements Discussion and Analysis of Financial Condition and Results of Operations section of our Annual Report on Form 10-K for the year ended December 31, 2006. Other than the adoption of FIN48 as
discussed in Note 6 to the accompanying condensed consolidated financial statements, there have been no material changes in theses critical accounting policies since December 31, 2006.

The preparation of financial statements and related disclosures in conformity with U.S. generally accepted accounting principles and our discussion and
analysis of our financial condition and results of operations require us to make judgments, assumptions, and estimates that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. We base our estimates
on historical experience and on various other assumptions we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. We regularly discuss with
our audit committee the basis of our estimates. Actual results may differ from these estimates and such differences may be material.

Results of
Operations

The following table summarizes results of operations data for the periods indicated. The percentages in the table are based
on total revenues with the exception of percentages for gross profit margins which are computed on related revenue.

Comparison of Three months ended June 30, 2007 to 2006

Revenues for the three months ended June 30, 2007
increased by 26% over the prior year quarter. Revenues in the IVD urinalysis segment increased to $18.0 million in the second quarter of 2007, from $13.8 million or 30% over the prior year quarter. Sales of IVD instruments increased to $8.6 million
from $6.0 million, a 42% increase. The increase in instrument sales is primarily due to increased domestic sales. We sell our instruments and consumables direct to customers domestically. In the international market, the average sale prices of the
iQ200 analyzer and related consumables are lower due to the fact that such sales, with the exception of France, are made through independent distributors in approximately 60 countries. International revenues accounted for approximately

##### Table of Contents

32% of consolidated revenue during the three months ended June 30, 2007 compared to 31% during the prior year quarter. We also continue to service and
support the installed base of legacy systems discontinued in 2004. IVD consumables and service revenue increased during the quarter to $9.4 million from $7.7 million, an increase of $1.7 million or 22% over the prior year quarter, primarily due to
the larger installed base of instruments. Revenues during the quarter from the sample processing instruments and supplies increased 6% to $3.0 million compared to $2.8 million for the prior year quarter primarily due to higher sales of the Express
2.

Unit volume of iQ200 Analyzers sold during the current quarter was 128, which is 25% higher than the 102 units sold during the second
quarter of 2006. Domestically, we sell the iQ200 microscopy analyzers either separately or combined with a chemistry analyzer, which we acquire from a Japanese supplier. The majority of domestic sales are sold as combined systems. Internationally,
we sell our iQ200 microscopy analyzer separately or with our semi-automated chemistry analyzer, as we do not have the distribution rights for the fully automated chemistry analyzer. We are currently developing an automated chemistry analyzer
internally which we anticipate will be introduced by the end of 2007.

Overall gross profit margins were constant at 51% in both the 2007
and 2006 second quarters in spite of the fact that IVD instruments (which generate lower gross margin than consumable products) represented 41% of consolidated revenues in the second quarter of 2007 vs. 36% of consolidated revenue in the second
quarter 2006. The gross profit margin of our IVD instruments improved to 49% during the second quarter compared to 46% during the prior year quarter, primarily due to the mix of instruments sold domestically versus internationally and a cost
reduction resulting from a change in the estimated accrual for laboratory information system implementations of approximately $250,000. The gross margin of our IVD consumables and services decreased to 53% during the quarter compared to 55% during
the prior year quarter. The decrease included a combination of losses in our German chemistry strip manufacturing operation acquired in June 2005, currently operating below capacity as well as increased costs associated with additional personnel for
domestic service in order to improve customer service response times. Our German strip manufacturing facility is expected to continue to operate below capacity until we launch our new automated urine chemistry analyzer later this year. Gross profit
margin for our sample processing laboratory instrument and supply segment improved to 52% in 2007 compared to 49% in 2006 due to the implementation of manufacturing cost reduction programs.

Marketing and selling expenses totaled $3.3 million, or 16% of revenue, for the current years second quarter, as compared to $2.6 million, or 16%
of revenue, in the second quarter of 2006. The increase includes additional personnel costs of $204,000; higher commissions paid of $263,000 as well as increased travel and related costs of $194,000 due to increased domestic sales.

General and administrative expenses decreased to $2.3 million compared to $2.8 million in the prior year primarily due to charges in 2006 of $500,000
related to a CFO transition, and $300,000 of higher bad debt expense in the prior year which was partially offset by an increase in professional fees in the 2007 quarter of $200,000 relating to higher audit and legal services.

Research and development expense amounted to $3.0 million during the second quarter of 2007 compared to $2.1 million in the same period in the prior year
quarter reflecting our continued investments in new product platforms in urinalysis and molecular diagnostics. The increased level of spending reflects the continued investment in the new chemistry analyzer which amounted to $700,000 during the
current quarter as well as increased headcount amounting to $200,000. The current year quarter was also impacted by the cost of closing down the AIDR subsidiary which amounted to approximately $163,000 during the quarter.

Interest income during the second quarter of 2007 amounted to $384,000, a $142,000 increase over the prior year quarter. The increase relates to our
continued investment of excess cash during the quarter, as well as interest earned on lease financing from the sale of instruments to customers. Our sales-type lease financings approximated $9.7 million during both periods.

Income tax expense during the second quarter of 2007 amounted to 30% of pre-tax income as compared to a $413,000 tax expense on the loss during the prior
year quarter. During the prior year, we purchased Leucadia Technologies in-process research and development totaling $5.2 million which was expensed for accounting purposes but not deductible for tax purposes. The tax provision continues to be
primarily a non-cash expense, since we have significant deferred tax assets relating to tax loss carryforwards and credits. As of January 1, 2007, federal tax loss carryforward amounted to approximately $9.4 million and research and development
tax credit carryovers totaled $3.9 million.

Comparison of Six months ended June 30, 2007 to 2006

Revenues for the six months ended June 30, 2007 increased by 26% over the prior year period. Revenues in the IVD urinalysis segment increased 31% to
$35.4 million in 2007, from $27.0 million in the prior year period. Sales of IVD instruments increased 43% to $17.1 million up from $12.0 million during the prior year period. The increase in instrument sales is primarily due to increased sales to
both domestic and international customers. International revenues accounted for approximately 32% of consolidated revenue during the six months ended June 30, 2007 compared to 33% during the prior year. IVD consumables and service revenue
increased to $18.3 million from $15.0 million, an increase of $3.3 million or 22% over the prior year, primarily due to the larger installed base of instruments. Revenues during the first six months from the sample processing instruments and
supplies were steady at $5.7 million for both periods. Unit volume of iQ200 instruments sold during the first six months of 2007 was 257, which is 26% higher than the 204 units sold during the prior year period.

Overall gross profit margins for the first six months was fairly constant at 50% during the current year period compared to 51% for the 2006 period in
spite of the fact that IVD instruments (which generate lower gross margin than consumable products) represented 42% of consolidated revenues in the first half of 2007 vs. 37 % of consolidated revenue in the first half of 2006. The gross profit
margin of our IVD instruments was improved to 47% in 2007 compared to 46% during the prior year, primarily due to the mix of instruments sold domestically versus internationally and a cost reduction resulting from a change in the estimated accrual
for laboratory information system implementations of approximately $250,000. The gross margin of our IVD consumables and services decreased to 53% during the quarter compared to 56% during the prior year quarter, primarily due to a combination of
losses generated in our German chemistry strip manufacturing, currently operating below capacity as well as increased costs associated with additional personnel for domestic service in order to improve customer service response times. Gross profit
margin for our sample processing laboratory instrument and supply segment increased to 50% in 2007 from 48% in 2006, primarily due to manufacturing cost improvement programs.

Marketing and selling expenses totaled $6.3 million, or 15% of revenue, for the first six months, as compared to $5.0 million, or 15% of revenue, in the
same period of 2006. The increase includes additional personnel costs of $409,000; higher commissions paid of $407,000; higher fees paid to GPOs (group purchasing organizations) of $81,000; increased travel and related costs of $306,000 due to
increased sales to domestic customers; and an increase of $78,000 in professional fees.

General and administrative expenses decreased
during the first six months to $4.7 million compared to $4.9 million in the prior year primarily due to decreased wages due to open positions in 2007 amounting to $335,000, and $500,000 of expense related to the CFO transition that occurred in 2006,
partially offset by $500,000 of increased professional fees.

Research and development expense amounted to $5.4 million during the first
six months of 2007 compared to $3.6 million in the same period in the prior year. The incremental spending in the new chemistry analyzer amounted to $700,000 as well as increased headcount amounting to $869,000 partially offset by a reduction in
government grant revenue of $226,000. The current year period also was impacted by the cost of closing down the ADIR subsidiary which amounted to approximately $163,000 during the quarter.

Interest income during the first six months of 2007 amounted to $723,000, a $218,000 increase over the same period in 2006. The increase relates to our
continued investment of excess cash during the quarter, as well as interest earned on lease financing from the sale of instruments to customers.

Income tax expense during the six months of 2007 amounted to 35% of pre-tax income as compared to $1.4 million tax on the loss during the prior year period. During the prior year, we purchased Leucadia Technologies in-process research
and development totaling $5.2 million which was expensed for accounting purposes but not deductible for tax purposes.

Off-Balance Sheet Arrangements

At June 30, 2007 and 2006, we did not have any relationships with unconsolidated entities or financial partnerships, such as
entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not
exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.

Liquidity and Capital Resources

Our primary source of liquidity is cash from operations, which depends heavily on sales of our IVD instruments, consumables and
service, as well as sales of sample processing instruments and supplies. At June 30, 2007, our cash and cash equivalents amounted to $25.6 million compared to $23.2 million at December 31, 2006.

##### Table of Contents

Operating Cash Flows.Cash provided by operations for the six months ended June 30, 2007
improved to $3.5 million as compared to $1.7 million during the prior year period. The $1.8 million improvement primarily results from the improvement in net income during the current period versus a net loss during the prior year period; a decrease
in the amount invested in inventories between periods of $1.9 million in 2007 versus 2006; a smaller decrease of accounts payable and accrued expenses of $610,000 plus a reduction in the amount of financing of sales-type lease transactions of
$174,000. These increases in cash were partially offset by smaller decreases in 2007 in receivables of $901,000 and an increase in 2007 in prepaid expenses and other assets of $962,000.

The relationship of receivables to revenues has increased over the prior year. The number of days sales in accounts receivable improved to 56 days at the
end of the first half of 2007 compared to 60 days for the prior year period. The number of days sales in inventory decreased to 63 days at the end of the first half of 2007 compared to 75 days at the beginning of the year. The lower number of days
sales in inventory is due to higher sales volume and improved inventory planning procedures including reduced safety stock on hand. In addition, the level of slow moving inventory on hand for the Legacy product line continued to decrease during the
first half of 2007.

Our cash flow continues to be favorably affected by the fact that at December 31, 2006 we had net operating tax
loss carry forwards into 2007 of $9.4 million for federal and $1.0 million for state as well as tax credit carry forwards of $2.2 million for federal and $1.7 million for state taxes. We continue to realize tax deductions from both the exercise of
stock options and the purchase by employees of our common stock at a discount to market. During the six months ended June 30, 2007, we realized additional tax deductions of approximately $312,000 from these items.

Investing Activities.Cash used in investing activities decreased to $2.0 million during the six months ended June 30, 2007, a $3.4 million
improvement over the prior year period primarily as a result of the acquisition in 2006 of Leucadia Technologies which amounted to $3.6 million.

Financing Activities.Cash provided by financing activities was approximately the same in the first half of 2007 and 2006 and resulted from issuances of common stock for cash of $645,000 during the 2007 period and $1.1 million during
the 2006 period. During the first half of 2007, we realized tax deduction benefits amounting to $312,000 from the exercise of stock options.

We currently have a credit facility with a commercial bank consisting of a $6.5 million revolving line of credit for working capital and a $10.0 million line of credit for acquisitions and product opportunities. Borrowings under the
revolving line of credit are limited to a percentage of eligible receivables and inventory. The entire credit facility has variable interest rates, which will change from time to time based on changes to either the LIBOR rate or the lenders
prime rate. As of June 30, 2007, there were no borrowings under the new credit facility. We are subject to certain financial covenants under the credit facility with the bank and as of June 30, 2007, we were in compliance with such
covenants.

We believe that our current cash on hand, together with cash generated from operations and cash available under the credit
facility with the bank will be sufficient to fund normal operations. However additional funding may be required to fund expansion of our business. There is no assurance that such funding will be available, on terms acceptable to us.

New Accounting Pronouncements

In September 2006, the
FASB issued SFAS 157, which addresses how companies should measure fair value when they are required to use a fair value measure for recognition or disclosure purposed under generally accepted accounting principles. As a result of SFAS 157, there is
a common definition of fair value to be used throughout GAAP; SFAS 157 is effective for fiscal years beginning after November 15, 2007. We are currently evaluating the impact of adopting SFAS 157 on our financial position and results of
operations.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial
Liabilities (SFAS 159), which provides entities with the option to measure certain financial instruments and other items at fair value, whereas those items are not currently required to be measured at fair value. SFAS 159 will be effective for
us on January 1, 2008. We are currently evaluating the impact of adopting SFAS 159 on our financial position and results of operations.

Inflation

We do not foresee any material impact on our operations from inflation.

Healthcare Reform Policies

In recent years, an increasing number of legislative proposals have been introduced or proposed in Congress and in some state legislatures that would
effect major changes in the healthcare system, nationally, at the state level or both. Future legislation, regulation or payment policies of Medicare, Medicaid, private health insurance plans, health maintenance organizations and other third-party
payors could adversely affect the demand for our current or future products and our ability to sell our products on a profitable basis. Moreover, healthcare legislation is an area of extensive and dynamic change, and we cannot predict future
legislative changes in the healthcare field or their impact on our business.



|Item 3. | Quantitative and Qualitative Disclosures About Market Risk
|------- | ----------------------------------------------------------

Market Risk

Our business is exposed to various market risks, including changes in interest rates and foreign currency
exchange rates. Market risk is the potential loss arising from adverse changes in market rates and prices, such as interest rates and foreign currency exchange rates. We do not invest in derivatives or other financial instruments for trading or
speculative purposes. We had no debt at June 30, 2007.

Foreign Currencies

We are subject to certain foreign currency risks in the importation of goods from Japan. Our purchases from this supplier are denominated in Japanese Yen.
These components represent a significant portion of our material costs. Fluctuations in the US Dollar/ Japanese Yen exchange rate could result in increased costs for our key components. Similarly, we are also exposed to currency fluctuations with
respect to the exportation of our products. With the exception of France which is denominated in Euros, all of our sales are denominated in US Dollars. Our strip manufacturing facility in Germany has the US Dollar as its functional currency.



|Item 4. | Controls and Procedures
|------- | -----------------------

(a) Evaluation of
Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as defined by paragraph (e) of Exchange Act
Rules 13a-15 or 15d-15, designed to ensure that we are able to collect the information we are required to disclose in the reports we file with the SEC and to approve, summarize and disclose this information within the time periods specified in the
rules of the SEC. Our Chief Executive Officer and Interim Chief Financial Officer are responsible for establishing and maintaining these procedures, and, as required by the rules of the SEC, evaluate their effectiveness. Our Chief Executive Officer
and Interim Chief Financial Officer have evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2007, the end of the period covered by this report, and based upon that evaluation, the Chief Executive Officer and
Interim Chief Financial Officer concluded that our disclosure controls and procedures are effective.

(b) Changes in Internal Controls
over Financial Reporting

There was no change in the Companys internal control over financial reporting that occurred during the
period covered by this Quarterly Report of Form 10-Q that materially affected, or is reasonable likely to materially affect, the Companys internal control over financial reporting.

Since the date of the most recent evaluation of our internal controls over our financial reporting by the Chief Executive Officer and Interim Chief
Financial Officer, we have identified certain significant deficiencies in such controls and plan to implement the following:



| |  |  | Financial Reporting Processa deficiency in the area of financial reporting was noted during the quarter ended June 30, 2007. Employee turnover affected the
timeliness of our financial reporting process and created delays in providing adequate supporting documentation for journal entries. We recorded post closing adjustments after our normal period-end closing process but before the filing of this
report. A new Chief Financial Officer was hired in August and the Company plans to add additional senior accounting and information technology personnel by the end of the year.
