NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

1 - Basis of Presentation

The accompanying interim condensed consolidated
financial statements of Natus Medical Incorporated (Natus, we, us, or the Company) have been prepared in accordance with accounting principles generally accepted in the United States of America
(GAAP). Except as updated below, the accounting policies followed in the preparation of the interim condensed consolidated financial statements are consistent in all material respects with those presented in Note 1 to the consolidated
financial statements included in the Companys Annual Report on Form 10-K for the year ended December 31, 2008.

Interim financial reports are prepared in accordance with the rules and regulations of the Securities and Exchange Commission; accordingly, they do not include all of the information and notes required by GAAP for annual financial
statements. The interim financial information is unaudited, but reflects all normal adjustments that are, in the opinion of management, necessary for the fair presentation of our financial position, results of operations, and cash flows for the
interim periods presented. Operating results for the three and nine months ended September 30, 2009 are not necessarily indicative of the results that may be expected for the year ending December 31, 2009. The accompanying condensed
consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

Foreign Currency

Effective January 1, 2009, the Companys Canadian subsidiary, Xltek changed its functional currency to the U.S. dollar. The change
in functional currency reflects the fact that Xltek now conducts the majority of its business transactions in U.S. dollars and maintains a significant portion of its balance sheet in U.S. dollar denominated accounts.

Recent Accounting Pronouncements

In June 2009, the Financial Accounting Standards Board (FASB) issued a Statement on Accounting Standards Codification. This Statement establishes the codification as the single official
source of authoritative United States accounting and reporting

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)(Continued)



standards for all non-governmental entities, other than guidance issued by the Securities and Exchange Commission. The codification changes the referencing and organization on financial standards
and is effective for interim and annual periods ending on or after September 15, 2009. We began applying the codification to our disclosures in the third quarter of 2009. As the codification is not intended to change existing accounting
guidance, its adoption has not had an impact on our financial position, results of operations, or cash flows.

In October
2009, the FASB issued Accounting Standards Update (ASU), 2009-13, Revenue Recognition (Topic 605): Multiple Deliverable Revenue Arrangements  A Consensus of the FASB Emerging Issues Task Force. This update provides
application guidance on whether multiple deliverables exist, how the deliverables should be separated and how the consideration should be allocated to one or more units of accounting. This update establishes a selling price hierarchy for determining
the selling price of a deliverable. The selling price used for each deliverable will be based on vendor specific objective evidence, if available, third-party evidence if vendor-specific objective evidence is not available, or estimated selling
price if neither vendor-specific or third-party evidence is available. This guidance applies prospectively for revenue arrangements entered into or materially modified after June 15, 2010, with earlier adoption permitted. We do not believe the
adoption of this guidance will have a material impact on our financial position, results of operations, or cash flows.

In May
2009, the FASB issued Accounting Codification Statement (ASC) Topic 855, Subsequent Events, which establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before
financial statements are issued. ASC 855-10 is effective for interim or annual financial periods ending after June 15, 2009. We adopted ASC 855-10 during our second quarter 2009 and have evaluated subsequent events through the date of this
filing. See Note 13.

In April 2009, ASC 825-10-65-1, Interim Disclosures about Fair Value of Financial Instruments,
was revised to require disclosures about fair value of financial instruments in interim as well as annual financial statements. This standard is effective for periods ending after June 15, 2009. We adopted the provisions of ASC 825-10-65-1 in
our second quarter 2009. The adoption of this guidance did not have a material impact on our financial position, results of operations, or cash flows; however we have added additional disclosures with respect to the fair value of our financial
instruments in Note 12 pursuant to the provisions of ASC 825-10-65-1.

In February 2009, ASC 805-20-35-3, Accounting for
Assets Acquired and Liabilities Assumed in a Business Combination That Arise from Contingencies, was revised. The revisions relate to the initial recognition and measurement, subsequent measurement, and disclosure of assets and liabilities
arising from contingencies in a business combination under ASC Topic 805. We adopted the provisions of ASC 805-20-35-3 on September 1, 2009 and applied these provisions to two business combinations completed during the third quarter 2009. See
Note 2.

In December 2007, the FASB issued ASC Topic 805, Business Combinations, which expands the definition of a
business combination and requires the fair value of the purchase price of an acquisition, including the issuance of equity securities, to be determined on the acquisition date. ASC Topic 805 also requires that all assets, liabilities, contingent
consideration and contingencies of an acquired business to be recorded at fair value at the acquisition date. In addition acquisition costs are generally expensed as incurred, restructuring costs generally are expensed in periods subsequent to the
acquisition date. Additionally, changes in accounting for deferred tax asset valuation allowances and acquired income tax uncertainties resulting from new information obtained during the measurement period about facts and circumstances that existed
as of the acquisition date will result in an adjustment to goodwill, while all other changes in these items are recognized as adjustments to income tax expense. We adopted ASC Topic 805 on January 1, 2009.

Alpine Biomed Holdings Corp.

We acquired Alpine Biomed Holdings
Corp. (Alpine Biomed) on September 14, 2009 pursuant to an Agreement and Plan of Merger. Alpine Biomed, with corporate headquarters in Fountain Valley, California and manufacturing facilities in Montreal, Canada, and Copenhagen,
Denmark, is a leader in the development, manufacturing, and sales of devices for the diagnosis of neurological disorders. Alpine Biomeds broad range of products includes advanced electromyography systems for the diagnoses of peripheral nervous
system dysfunctions as well as devices for routine EEG and long term epilepsy monitoring.

We acquired all outstanding shares of Alpine Biomed capital stock for $43.2 million in
cash and assumed a contingent obligation valued at $600,000. The contingent obligation is associated with an earn out provision of the purchase agreement that may result in the payment of additional cash consideration to the former shareholders of
Alpine Biomed based on the achievement of a certain revenue target as of December 31, 2009. The contingent obligation was recorded as a current liability. We also incurred $345,000 of direct costs associated with the acquisition that were
expensed as a component of general and administrative expense in the third quarter 2009.

In accordance with ASC 805-10, the
acquisition has been accounted for as a purchase business combination. Under the purchase method of accounting, the assets acquired and liabilities assumed from Alpine Biomed at the date of acquisition are recorded in the consolidated financial
statements at their respective fair values as of the acquisition date. The excess of the purchase price over the fair value of the acquired net assets has been recorded as goodwill in the amount of $26.4 million. This goodwill is expected to be
non-deductible for tax purposes. Alpine Biomeds results of operations are included in the consolidated financial statements from the date of the acquisition.

The determination of estimated fair value of acquired assets and liabilities requires management to make significant estimates and assumptions. We determined the fair value by applying established
valuation techniques, based on information that management believed to be relevant to this determination. The following table summarizes the preliminary purchase price allocation of the fair value of the assets acquired and liabilities assumed at
the date of acquisition, as adjusted (in thousands):

Valuing certain components of the acquisition, including primarily accounts
receivable, inventory, prepaid expenses, identifiable intangible assets, goodwill, deferred taxes, accrued warranty costs, accounts payable, other accrued expenses, and deferred revenue, required us to make estimates that may be adjusted in the
future. In addition, we have not completed a reconciliation of intercompany account balances among Alpine Biomed and its subsidiaries. Consequently, the purchase price allocation is considered preliminary.

Identifiable intangible assets.Intangible assets included in the purchase price allocation consist of: (a) technology of $5.8
million assigned an average economic life of 20 years being amortized on the straight line method, (b) customer-related intangible assets of $4.9 million assigned an economic life of 15 years being amortized on the straight line method, and
(c) tradenames of $4.7 million that have an indefinite life and are not being amortized.

Goodwill. Approximately
$26.4 million has been allocated to goodwill. Goodwill represents the excess of the purchase price over the fair value of the underlying net tangible and intangible assets. In accordance with ASC 350-20, goodwill will not be amortized but
instead will be tested for impairment at least annually (more frequently if certain indicators are present). In the event that management determines that the value of goodwill has become impaired, we will incur an accounting charge for the amount of
impairment during the fiscal quarter in which the determination is made.

Deferred tax assets (liabilities) / valuation allowance. A preliminary estimate
of $4.7 million has been allocated to non-current deferred tax assets, and $3.0 million has been allocated to non-current deferred tax liabilities, which result primarily from amortizable intangible assets. A preliminary valuation allowance of $1.9
million has been recorded on certain non-current deferred tax assets.

the pro forma financial results do not purport to be indicative of results of operations as of the date hereof, for any period ended on the date hereof, or for any other future date or period.

Hawaii Medical

We acquired Hawaii Medical, LLC on July 2, 2009 pursuant to an Agreement and Plan of Merger. Massachusetts based Hawaii Medical manufactures and markets single-use disposable products sold into the
NICU and nursery in hospitals.

We acquired all outstanding units of Hawaii Medical for $2.9 million in cash. In addition to
the purchase price paid at closing, an earn out provision of the purchase agreement may result in additional cash consideration depending upon the achievement of certain revenue targets over a 36 month period. Although there is no limit to the
additional consideration that will be paid if the revenue targets are exceeded, no contingent obligation has been recorded as there is significant uncertainty that the revenue targets will be achieved. We also incurred $115,000 of direct costs
associated with the acquisition that were expensed as a component of general and administrative expense in the third quarter 2009.

In accordance with ASC 805-10, the acquisition has been accounted for as a purchase business combination. Under the purchase method of accounting, the assets acquired and liabilities assumed from Hawaii Medical at the date of acquisition
are recorded in the consolidated financial statements at their respective fair values as of the acquisition date. The excess of the purchase price over the fair value of the acquired net assets has been recorded as goodwill in the amount of $2.4
million. This goodwill is expected to be non-deductible for tax purposes. Hawaii Medicals results of operations are included in the consolidated financial statements from the date of the acquisition.

The determination of estimated fair value requires management to make significant estimates and assumptions. We determined the fair value by
applying established valuation techniques, based on information that management believed to be relevant to this determination. The following table summarizes the preliminary purchase price allocation of the fair value of the assets acquired and
liabilities assumed at the date of acquisition, as adjusted (in thousands):

Valuing certain components of the acquisition, including primarily inventory, required
us to make estimates that may be adjusted in the future; consequently, the purchase price allocation is considered preliminary.

Identifiable intangible assets.Intangible assets included in the purchase price allocation consisting of tradenames valued at $300,000 have an indefinite life and are not being amortized.

Goodwill. Approximately $2.4 million has been allocated to goodwill.

Neurocom

We acquired Neurocom International Inc. (Neurocom) on October 2, 2008. Neurocom, based in Clackamas, Oregon, develops and markets computerized systems for the assessment and rehabilitation of balance and mobility disorders.
The acquisition added to our growth opportunities by broadening the product offerings in our neurology business.

We acquired
all outstanding shares of Neurocom for $18.2 million in cash including direct costs of the acquisition.

Valuing certain
components of the acquisition, including primarily accrued warranty costs and other accrued expenses, required us to make estimates that may be adjusted in the future; consequently, the purchase price allocation is considered preliminary.

Schwarzer Neurology

We acquired Schwarzer Neurology, a division of Schwarzer GmbH, on July 2, 2008. Schwarzer Neurology develops and markets computer-based electrodiagnostic systems and disposable supplies used by
medical practitioners to aid in the detection, diagnosis, and monitoring of neurologic disorders. The acquisition broadened our product offerings in the EEG market, allowing us to further leverage its international distribution organization.

We acquired the assets of Schwarzer Neurology for EUR 4.5 million, or approximately $7.0 million, including direct costs
of the acquisition. We were obligated to make additional payments pursuant to an earnout provision in the purchase agreement based on the achievement of certain revenue targets through September 30, 2009. The revenue targets were not achieved
and no additional purchase consideration was or will be paid.

Olympic

We acquired Olympic Medical on October 16, 2006 for $16.9 million. To date we have recorded $1.6 million of additional purchase
consideration pursuant to an earnout provision in the purchase agreement based on the achievement of certain revenue targets for sales of the Olympic Cool-Cap. At September 30, 2009 the maximum potential future amount payable under this
provision, based on sales results from January 1, 2009 through December 31, 2009, is $1.5 million.

Capitalized Software Development Costs

Pursuant to ASC 350-40, we capitalized software development costs of $293,000 and $637,000 during the three and nine months ended
September 30, 2009, respectively, and $372,000 and $1.2 million during the three and nine months ended September 30, 2008, respectively.

We report capitalized software development costs as a component of intangible assets. Amortization of capitalized software development costs was $50,000 and $235,000 during the three and nine months ended
September 30, 2009, respectively, and $36,000 during the three and nine months ended September 30, 2008.

3 - Basic and Diluted
Earnings Per Common Share

Earnings per share is computed in accordance with ASC 260-10.Basic earnings per share is
based upon the weighted average number of common shares outstanding during the period. Diluted earnings per share is based upon the weighted average number of common shares outstanding and dilutive common stock equivalents outstanding during the
period. Common stock equivalents are options granted and shares of restricted stock issued under our stock awards plans and are calculated under the treasury stock method. Common equivalent shares from unexercised stock options and restricted stock
are excluded from the computation when there is a loss as their effect is anti-dilutive, or if the exercise price of such options is greater than the average market price of the stock for the period.

For the three and nine months ended September 30, 2009, common stock equivalents of 998,969 and 702,751 shares, respectively, were
included in the weighted average shares outstanding used to calculate diluted earnings per share. For the three and nine months ended September 30, 2009, common stock equivalents of 1,411,152 and 1,594,888 shares, respectively, were excluded
from the calculation of diluted earnings per share because the exercise price of such options was greater than the average market price of the stock for the periods. For the three and nine months ended September 30, 2008, common stock
equivalents of 1,311,262 and 1,277,836 shares, respectively, were included in the weighted average shares outstanding used to calculate diluted earnings per share. For the three and nine months ended September 30, 2008, common stock equivalents
of 366,551 and 220,254 shares, respectively, were excluded from the calculation of diluted earnings per share because the exercise price of such options was greater than the average market price of the stock for the periods.

Depreciation and amortization expense of property and equipment was $313,000 and $2.4

6 - Reserve for Product Warranties

We provide a warranty on all medical device products that is generally one year in length. We also sell extended service agreements on our medical device products. Service for domestic customers is provided by Company-owned service centers
that perform all service, repair and calibration services. Service for international customers is provided by a combination of Company-owned facilities and third-party vendors on a contract basis.

We have accrued a warranty reserve, included in accrued liabilities on the accompanying condensed consolidated balance sheets, for the
expected future costs of servicing products during the initial warranty period. Amounts are added to the reserve on a per-unit basis by reference to historical experience in honoring warranty obligations. On new products, where we do not have
historical experience of the cost to honor warranties, additions to the reserve are based on a combination of factors including the standard cost of the product and other judgments, such as the degree to which the product incorporates new
technology. As warranty costs are incurred, the reserve is reduced.

The details of activity in the warranty reserve are as
follows (in thousands):

9 - Income Taxes

Provision for Income Tax

We recorded a provision for income tax of
$1.6 million and $3.5 million for the three and nine months ended September 30, 2009, respectively. Our effective tax rate was 30.0% and 33.9% for the three and nine months ended September 30, 2009, respectively. Our effective tax rate was
lower in the third quarter than in previous quarters because of a number of discrete adjustments to the tax provision, including primarily the impact of foreign currency fluctuations on deferred tax assets and liabilities of our Xltek subsidiary.

We recorded a provision for income tax of $2.7 million and $6.8 million for the three and nine months ended
September 30, 2008, respectively. Our effective tax rate was 36.1% and 37.8% for the three and nine months ended September 30, 2008, respectively.

Deferred Income Taxes

We account for income taxes in accordance
with ASC 740-10, which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. ASC 740-10 also requires that
deferred tax assets be reduced by a valuation allowance if it is more likely than not that some or all of the deferred tax assets will not be realized. We believe that it is more likely than not that most of our deferred tax assets will be fully
realized; therefore, a valuation allowance has been provided for only a small portion of our deferred tax assets.

Uncertain Tax Positions

We have cumulatively accrued approximately $639,000 for estimated interest and
penalties related to uncertain tax positions at September 30, 2009. We recorded approximately $51,000 and $153,000 of interest and penalties related to unrecognized tax positions as a component of income tax expense during the three and nine
months ended September 30, 2009, respectively, and $69,000 and $207,000 during the three and nine months ended September 30, 2008, respectively.

Our tax returns remain open to examination as follows: U.S. federal, 2004 through 2008; U.S. states, generally 2003 through 2008; significant foreign jurisdictions, generally 2005 through 2008.

On September 2, 2008, we executed a second amendment to our Amended and Restated
Credit Agreement (the Second Amendment) with Wells Fargo Bank, National Association (Wells Fargo). The Second Amendment increased the borrowing limit of our revolving line of credit to $25 million and made other changes to
the terms of the credit facility. Additional revisions to the credit facility were executed in February 2009, June 2009 and September 2009. The credit facility contains covenants, including covenants relating to liquidity and other financial
measurements, and provides for events of default, including failure to pay any interest when due, failure to perform or observe covenants, bankruptcy or insolvency events, and the occurrence of a material adverse effect. We have granted Wells Fargo
a security interest in all of our assets. As of September 30, 2009 there were no outstanding borrowings on the credit facility.

In accordance with ASC Topic 820, Fair Value Measurements, Level 1 evaluations
are based on quoted prices in active markets for identical assets or liabilities that we have the ability to access. Level 2 evaluations are based on quoted prices in markets that are not active or for which all significant inputs are observable,
either directly or indirectly. Bank money market accounts have a net asset value of $1.00 per share and are classified as Level 2 assets. Level 3 evaluations are based on assets and liabilities for which there are no observable inputs that are
significant to the overall fair value measurement.

13 - Subsequent Events

We evaluated all subsequent events from the date of the balance sheet through November 9, 2009, which represents the date these
financial statements are being filed with the SEC. There were no events or transactions occurring during this subsequent event reporting period which require recognition or disclosure in the financial statements.

During the three and nine months ended September 30, 2009, no single customer or
foreign country contributed to more than 10% of revenue, and revenue from services was less than 10% of revenue.

2009
Third Quarter Overview

Our revenue increased 6% to $44.3 million in the third quarter ended September 30, 2009,
compared to $41.7 million reported in the comparable quarter of the previous year. Net income decreased 23% to $3.7 million, or $0.13 per diluted share, for the third quarter of 2009, compared with net income of $4.8 million, or $0.17 per diluted
share, for the third quarter of 2008. The increase in revenue in 2009 compared to the same period in 2008 was primarily attributable to our recent acquisitions.

The severe worldwide economic downturn that started to impact our business in December 2008 continued to influence our results for the third quarter of 2009. In the quarter, hospitals in the United States
reduced expenditures on capital equipment, but the decrease was less than in the first half of 2009. This impacted sales of all of our product lines except our newborn care products. We saw a small increase in capital equipment spending outside the
United States. Revenue from our neurology, balance and mobility, hearing diagnostic, and newborn hearing equipment products were all down by at least 11% year over year, but increased sequentially over our 2009 second quarter.

We acquired Hawaii Medical on July 2, 2009 for $2.9 million in cash, with the potential for additional consideration depending upon the
achievement of certain revenue targets. Hawaii Medical, which manufactures and markets single-use disposable products sold into the nursery and neonatal intensive care unit (NICU) in hospitals.

We acquired Alpine Biomed on September 14, 2009, for $43.2 million in cash, with the
potential for additional consideration depending upon the achievement of certain revenue targets. Alpine Biomed is a leader in the development, manufacturing, and sales of devices for the diagnosis of neurological disorders.

Please see Note 2 - Business Combinations, Goodwill, and Intangible Assets of our condensed consolidated financial statements included in
this report for additional information regarding the terms of these acquisitions

Application of Critical Accounting
Policies

We prepare our financial statements in accordance with accounting principles generally accepted in the United
States of America (GAAP). In so doing, we must often make estimates and use assumptions that can be subjective, and, consequently, our actual results could differ from those estimates. For any given individual estimate or assumption we
make, there may also be other estimates or assumptions that are reasonable.

We believe that the following critical accounting
policies require the use of significant estimates, assumptions, and judgments. The use of different estimates, assumptions, or judgments could have a material affect on the reported amounts of assets, liabilities, revenue, expenses, and related
disclosures as of the date of the financial statements and during the reporting period:



| |  |  | Revenue recognition
| | - |  | -------------------



| |  |  | Allowance for doubtful accounts
| | - |  | -------------------------------



| |  |  | Inventory is carried at the lower of cost or market value
| | - |  | ---------------------------------------------------------



| |  |  | Carrying value of intangible assets and goodwill
| | - |  | ------------------------------------------------



| |  |  | Liability for product warranties
| | - |  | --------------------------------



| |  |  | Share-based compensation
| | - |  | ------------------------

These critical accounting policies are described in more detail in our Annual Report on Form 10-K for the year ended December 31, 2008, under Item 7, Managements Discussion and Analysis
of Financial Condition and Results of Operations. There have been no changes to these policies during the three and nine months ended September 30, 2009.

Certain reclassifications have been made to the prior period classification of revenue as
devices and systems or supplies and services to conform to the current presentation.

We acquired Neurocom in October 2008,
Hawaii Medical in July 2009, and Alpine Biomed in September 2009. Where significant, we have noted the impact of these acquisitions on our results of operations for the three and nine months ended September 30, 2009, as compared to the same
periods in 2008.

Three Months Ended September 30, 2009 and 2008

Revenue increased $2.5 million, or 6%, for the three month period ended September 30, 2009 from the comparable 2008 period. The increase
was due primarily to the acquisition of NeuroCom, Hawaii Medical and Alpine Biomed which contributed to $6.1 million of revenue offset by a $3.6 million decrease in capital equipment revenue.

Device and systems revenue decreased $922,000, or 3.7%, to $23.8 million in the three months ended September 30, 2009 compared to $24.7
million in the same period in 2008. NeuroCom and Alpine Biomed contributed to $4.2 million of revenue from devices and systems offset by a $3.5 million decrease in revenue from other neurology products, and a $1.6 million decrease in revenue from
other products. Revenue from devices and systems was 54% of consolidated revenue in the three months ended September 30, 2009 compared to 59% of consolidated revenue for the third quarter of 2008.

Supplies and services revenue increased 21.4%, or $3.5 million, to $19.7 million in the third quarter of 2009 compared to $16.2 million in
the same period in 2008. In the 2009 third quarter, revenue from hearing screening and neurology supplies increased by $2.3 million and service fees increased by $1.2 million. Revenue from supplies and services was 44% of consolidated revenue in the
three months ended September 30, 2009 compared to 39% of consolidated revenue for the third quarter of 2008.

Revenue
from sales outside the U.S. increased $2.3 million, or 19.9%, to $14.1 million in the third quarter of 2009 compared to $11.8 million for the same period in 2008. Neurocom and Alpine Biomed contributed to $2.8 million of international revenue,
offset by $500,000 decrease in revenue from other devices and systems.

Gross profit as a percentage of revenue was 60.6% for
the three months ended September 30, 2009 compared to 62.0% for the respective period in 2008. The lower margin in the 2009 period reflects higher manufacturing overhead costs, primarily associated with the transfer of manufacturing operations
of Hawaii Medical products to our Olympic facility in Seattle. We also accrued $460,000 of severance costs for production personnel at Xltek and at our corporate facility in San Carlos, California during the third quarter of 2009. These severance
costs reflect our continued effort to outsource manufacturing to contract manufacturers. These severance costs reduced our third quarter 2009 gross profit by 1.0%.

Cost of revenue increased $1.6 million, or 10.2%, to $17.4 million in the three months ended September 30, 2009, from $15.8 million in 2008, reflecting lower margins on sales in the 2009 period.
Gross profit increased $922,000, or 3.6%, to $26.8 million in the third quarter of 2009, from $25.9 million in the third quarter of 2008.

Total operating costs increased by $2.7 million or 14.2%, to $21.6 million in the three months ended September 30, 2009, compared to $18.9 million in the same period in 2008. Neurocom and Alpine
Biomed contributed to $2.5 million of the increase.

Marketing and selling expenses increased $1.8 million, or 18.1%, to $11.8
million in the three months ended September 30, 2009 compared to $10.0 million in the same period in 2008. Neurocom and Alpine Biomed contributed to $1.4 million of marketing and selling expenses, while other marketing and selling expenses were
approximately 4% higher in the third quarter of 2009 compared to the same period in 2008 reflecting higher salary and commission related expenses.

Research and development expenses increased $109,000, or 2.7%, to $4.2 million for the three months ended September 30, 2009 compared to $4.1 million in the same period of 2008. Neurocom and Alpine
Biomed contributed to $334,000 of research and development expenses, while other research and development expenses were approximately 5% lower in the third quarter of 2009 compared to the same period in 2008. The reduction in research and
development expenses exclusive of Neurocom and Alpine Biomed reflects the impact of our 2008 restructuring plan and lower outside service costs.

General and administrative expenses increased $775,000, or 15.8%, to $5.7 million in the
three months ended September 30, 2009 compared to $4.9 million in the same period in 2008. During the third quarter 2009 Neurocom and Alpine Biomed contributed to $627,000 of general and administrative expenses for which we had no such costs in
the 2009 period. We also recorded $460,000 of direct acquisition costs associated with the acquisitions of Hawaii Medical and Alpine Biomed in the third quarter 2009. Other general and administrative expense exclusive of those associated with
Neurocom and Alpine, and the referenced acquisition costs, were $312,000 less in the 2009 third quarter compared to the same period in 2008, which resulted primarily from a reduction in outside consulting expenses.

We adopted an integration and restructuring plan in February 2008 that was designed to reduce redundant costs resulting from prior
acquisitions and to improve efficiencies in operations. These actions were phased in during the first nine months of 2008. Costs under the plan, which were primarily for severance benefits, stay bonuses, and duplicative salaries, totaled
approximately $700,000. We accrued $460,000 and $64,000 of employee termination benefits in the three months ended September 30, 2009 and 2008, respectively.

Other income, net consists of investment income from our investment portfolio, interest expense, net currency exchange gains and losses, and other miscellaneous income and expenses. We reported other
income, net of $71,000 in the three months ended September 30, 2009, compared to $567,000 in the same period in 2008, due primarily to lower rates of interest earned on our investment portfolio; however we expect this trend will continue, even
if interest rates rise, as our investment portfolio has decreased as a result of our recent acquisitions.

We recorded income
tax expense of $1.6 million in the three months ended September 30, 2009, compared to $2.7 million in the same period in 2008. Our effective tax rate in the third quarter of 2009 was 30.0% compared to an effective rate of 36.1% in the third
quarter of 2008 and 38.0% for the first six months of 2009. Our effective tax rate was lower in the third quarter 2009 than in previous quarters because of a number of discrete adjustments to the tax provision, including primarily the impact of
foreign currency fluctuations on deferred taxes of our Xltek subsidiary. Because the functional currency of Xltek became the U.S. Dollar on January 1, 2009, deferred tax assets and liabilities of Xltek are revalued to the Canadian Dollar
and the net change in value is reported as a component of our tax provision. We expect that this revaluation will increase the volatility in our effective tax rate in the future.

Nine Months Ended September 30, 2009 and 2008

Revenue decreased $3.6 million, or 3.0%, for the nine month period ended September 30, 2009 from the comparable 2008 period. The
decrease was due primarily to lower capital equipment sales across all of our product lines. We believe that these lower sales resulted from weakness in demand due to the current economic recession and not a loss of market share. Neurocom, Hawaii
Medical and Alpine Biomed contributed to $9.7 million of revenue offset by a $13.3 million decrease in revenue from our other capital equipment products.

Device and systems revenue decreased $8.0 million, or 10.9%, to $63.6 million in the nine months ended September 30, 2009 compared to $71.6 million in the same period in 2008. Neurocom and Alpine
Biomed contributed to $7.8 million of revenue from devices and systems offset by a $10.8 million decrease in revenue from other neurology and sleep diagnostics products, a $3.7 million decrease in revenue from hearing products, and a $1.2 million
decrease in revenue from newborn care and other products. Revenue from devices and systems was 55.4% of consolidated revenue in the nine months ended September 30, 2009 compared to 60.4% of consolidated revenue for the same period in 2008.

Supplies and services revenue increased $4.5 million, or 10.2%, to $49.0 million in the nine months ended September 30,
2009 compared to $44.5 million in the same period in 2008. NeuroCom, Hawaii Medical and Alpine Biomed contributed to $2.4 million of revenue from supplies and services and sales of Neurology supplies increased by $2.1 million. Revenue from supplies
and services was 42.7% of consolidated revenue in the nine months ended September 30, 2009 compared to 37.6% of consolidated revenue for the nine months ended September 30, 2008.

Revenue from sales outside the U.S. increased $855,000, or 1.7%, to $36.1 million in the nine months ended September 30, 2009 compared
to $35.2 million for the same period in 2008. Neurocom and Alpine Biomed contributed to $4.0 million of international revenue. International device and systems revenue decreased $2.8 million, reflecting the impact of the economic recession in
international markets, while international hearing and newborn care supplies revenue increased $1.5 million during the 2009 period.

Gross profit as a percentage of revenue was 60.9% for the nine months ended September 30, 2009 compared to 61.8% for the respective period in 2008. The lower margin reflects higher materials and manufacturing overhead costs in the 2009
period included the $460,000 of severance costs recorded in the third quarter of 2009. These severance costs reduced our third quarter 2009 gross profit by 0.5%.

Total operating costs increased by $4.1 million or 7.3%, to $60.3 million in the nine months
ended September 30, 2009, compared to $56.2 million in the same period in 2008. Neurocom and Alpine Biomed contributed to $4.8 million of total operating costs, while other operating costs were approximately 1.2% lower in the nine months ended
September 30, 2009 compared to the same period in 2008. The reduction in operating expenses exclusive of Neurocom and Alpine Biomed reflects the impact of our 2008 restructuring plan and the implementation of tighter cost controls.

Marketing and selling expenses increased $3.0 million, or 10.3%, to $32.0 million in the nine months ended September 30, 2009
compared to $29.0 million in the same period in 2008. Neurocom and Alpine Biomed contributed to $3.4 million of marketing and selling expenses, while other marketing and selling expenses were approximately 1% lower in the nine months ended
September 30, 2009 compared to the same period in 2008.

Research and development expenses decreased $122,000, or 1.0%,
to $11.8 million for in the nine months ended September 30, 2009 compared to $12.0 million in the same period of 2008. Neurocom and Alpine Biomed contributed to $715,000 of research and development expenses, while other research and development
expenses were approximately 7% lower in the nine months ended September 30, 2009 compared to the same period in 2008. The reduction in research and development expenses exclusive of Neurocom and Alpine Biomed reflects the impact of our 2008
restructuring plan.

General and administrative expenses increased $1.3 million, or 8.2%, to $16.5 million in the nine months
ended September 30, 2009 compared to $15.2 million in the same period in 2008. During the third quarter 2009 Neurocom and Alpine Biomed contributed to $902,000 of general and administrative expenses, and the direct costs of acquiring Hawaii
Medical and Alpine Biomed totaling $460,000 were expensed.

We adopted an integration and restructuring plan in February 2008
that was designed to reduce redundant costs resulting from prior acquisitions and to improve efficiencies in operations. These actions were phased in during the first nine months of 2008. Costs under the plan, which were primarily for severance
benefits, stay bonuses, and duplicative salaries, totaled approximately $700,000. Pursuant to the plan, we accrued $460,000 and $301,000 of employee termination benefits in the nine months ended September 30, 2009 and 2008, respectively.

Other income, net consists of investment income from our investment portfolio, interest expense, net currency exchange gains
and losses, and other miscellaneous income and expenses. We reported net other income of $584,000 in the nine months ended September 30, 2009, compared to $954,000 in the same period in 2008 due primarily to lower exchange gains and lower
investment income offset by reduced interest expense in 2009 compared to the same period in 2008.

We recorded income tax
expense of $3.5 million in the nine months ended September 30, 2009, compared to $6.8 million in the same period in 2008. Our effective tax rate in the first nine months of 2009 was 33.9% compared to an effective rate of 37.8% in the same
period in 2008. Our tax rate was lower in the 2009 period because of the impact of foreign currency changes on deferred taxes at our Xltek subsidiary and because more of our income is taxed in foreign jurisdictions with lower tax rates than our
consolidated effective tax rate.

Liquidity and Capital Resources

Liquidity is our ability to generate sufficient cash flows from operating activities to meet our obligations and commitments. In addition,
liquidity includes the ability to obtain appropriate financing or to raise capital. Therefore, liquidity cannot be considered separately from capital resources that consist of our current funds and the potential to increase those funds in the
future. We plan to use our capital resources in meeting our commitments and in achieving our business objectives.

As of
September 30, 2009, we had cash and cash equivalents of $28.7 million, short-term investments of $944,000, stockholders equity of $238.3 million, and working capital of $73.7 million, compared with cash and cash equivalents of $56.9
million, stockholders equity of $226.5 million, and working capital of $102.3 million as of December 31, 2008.

We
believe that our current cash, cash equivalents, and short-term balances, including cash generated from operations, will be sufficient to meet our ongoing operating and capital requirements for the foreseeable future. We completed two acquisitions
in 2009, three acquisitions in 2008, one in 2007, and three in 2006. We intend to continue to acquire additional technologies, products or businesses, and these acquisitions could be significant. These actions will likely affect our future capital
requirements and the adequacy of our available funds. We may be required to raise additional funds through public or private financings, strategic relationships, or other arrangements. Any equity financing may be dilutive to stockholders, and debt
financing, if available, may involve restrictive covenants and increase our cost of capital.

On September 2, 2008, we executed a second amendment to our Amended and Restated Credit
Agreement (the Second Amendment) with Wells Fargo Bank, National Association (Wells Fargo). The Second Amendment increased the borrowing limit of our revolving line of credit to $25 million and made other changes to the terms
of the credit facility. Additional revisions to the credit facility were executed in February 2009, June 2009 and September 2009. The credit facility contains covenants, including covenants relating to liquidity and other financial
measurements, and provides for events of default, including failure to pay any interest when due, failure to perform or observe covenants, bankruptcy or insolvency events and the occurrence of a material adverse effect. We have granted Wells Fargo a
security interest in all of our assets.

Cash provided by operations increased by $16.7 million for the nine months ended
September 30, 2009 to $20.9 million, compared to $4.2 million for the same period in 2008. The sum of our net income and non-cash expense items, such as reserves, depreciation and amortization, and stock based compensation, was approximately
$17.9 million in the 2009 period, compared to $16.7 million in 2008. The overall impact of changes in certain operating assets and liabilities on total operating cash flows resulted in a cash inflow of $3.0 million in 2009 compared with a cash
outflow of $12.5 million in 2008.

Cash used in investing activities was $50.6 million for the nine months ended
September 30, 2009 compared to $18.1 million for the same period in 2008. During the nine months ended September 30, 2009 we paid $47.1 million for acquired businesses and earnout obligations, net of cash acquired, and $944,000 for
investment in marketable securities, compared to $13.8 million paid for net business acquisitions and $12.1 million for marketable securities in 2008. We paid $1.9 million for purchases of property and equipment for the nine months ended
September 30, 2009 compared to $2.2 million in the same period of 2008, and capitalized $637,000 of internal use software development costs in 2009 compared to $1.2 million in 2008.

Cash provided by financing activities was $188,000 during the nine months ended September 30, 2009, compared to $68.8 million in the
same period in 2008. We raised cash through sales of our stock pursuant to our stock awards plans and our employee stock purchase plan in the amount of $542,000 and $2.6 million in the nine months ended September 30, 2009 and 2008,
respectively. We raised an aggregate of $99.3 million through underwritten public offerings of our common stock in April and May 2008 with no similar transactions in 2009. We also realized an excess tax benefit of $31,000 on the exercise of employee
stock options for the nine months ended September 30, 2009 that was recorded as an increase to stockholders equity, as compared with a tax benefit of $2.1 million in the first nine months of 2008. During the nine months ended
September 30, 2008, we increased our borrowings under our credit facility by $6.0 million and we repaid $25.2 million on our term loan and $16.0 million on our revolving credit facility resulting in a net cash outflow of $41.2 million for the
nine months ended September 30, 2008, compared with payments of $385,000 for the nine months ended September 30, 2009.

Our future liquidity and capital requirements will depend on numerous factors, including the:



| |  |  | Amount and timing of revenue;
| | - |  | -----------------------------



| |  |  | Extent to which our existing and new products gain market acceptance;
| | - |  | ---------------------------------------------------------------------



| |  |  | Extent to which we make acquisitions;
| | - |  | -------------------------------------



| |  |  | Cost and timing of product development efforts and the success of these development efforts;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | Cost and timing of marketing and selling activities; and
| | - |  | --------------------------------------------------------



| |  |  | Availability of borrowings under line of credit arrangements and the availability of other means of financing.
| | - |  | --------------------------------------------------------------------------------------------------------------

Commitments and Contingencies

In the normal course of business, we enter into obligations and commitments that require future contractual payments. The commitments primarily result from firm, noncancellable purchase orders placed with
contract vendors that manufacture some of the components used in our medical devices and related disposable supply products, as well as commitments for leased office, manufacturing, and warehouse facilities. There have been no material changes to
the table of contractual obligations presented in Item 7, Managements Discussion and Analysis of Financial Condition and Results of Operations, of our Annual Report on Form 10-K for the year ended December 31, 2008.

Under our bylaws, we have agreed to indemnify our officers and directors for certain events or occurrences arising as a
result of the officer or director serving in such capacity. We have a directors and officers liability insurance policy that limits our exposure and enables us to recover a portion of any amounts paid resulting from the indemnification
of our directors and officers. In addition, we enter into indemnification agreements with other parties in the ordinary course of business. We believe the estimated fair value of these indemnification agreements is minimal and we have not recorded a
liability for these agreements.

Recent Accounting Pronouncements

See Note 1 to our Condensed Consolidated Financial Statements for a discussion of new accounting pronouncements that affect us.

Cautionary Information Regarding Forward Looking Statements

This report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E
of the Securities Exchange Act of 1934 about Natus Medical Incorporated. These statements include, among other things, statements concerning our expectations, beliefs, plans, intentions, future operations, financial condition and prospects, and
business strategies. The words may, will, continue, estimate, project, intend, believe, expect, anticipate, and other similar expressions
generally identify forward-looking statements. Forward-looking statements in this Item 2 include, but are not limited to, statements regarding the following: our effective tax rate for 2009, our expectation that the reduction in capital
equipment purchases has stabilized and will not further deteriorate, our expectation regarding expansion of our international operations, our expectations regarding our new products, the sufficiency of our current cash, cash equivalents, and
short-term investment balances, and any cash generated from operations to meet our ongoing operating and capital requirements for the foreseeable future, our expectations with respect to integration of products acquired from Hawaii Medical, our
expectations with respect to the acquisition of Alpine Biomed being accretive in the fourth quarter, and our intent to acquire additional technologies, products, or businesses.

Forward-looking statements are not guarantees of future performance and are subject to substantial risks and uncertainties that could
cause the actual results predicted in the forward-looking statements as well as our future financial condition and results of operations to differ materially from our historical results or currently anticipated results. Investors should carefully
review the information contained under the caption Risk Factors contained in Part II, Item 1A of this report for a description of risks and uncertainties. All forward-looking statements are based on information available to us on
the date hereof, and we assume no obligation to update forward-looking statements.



|ITEM 3. | Quantitative and Qualitative Disclosures about Market Risk
|------- | ----------------------------------------------------------

We develop products in the U.S., Canada, and Europe and sell those products primarily in the U.S., Europe and Asia. As a result, our financial results could be affected by factors such as changes in
foreign currency exchange rates or weak economic conditions in foreign markets. Most of our sales in Europe and Asia are denominated in U.S. dollars and Euros, and with the acquisition of Xltek in November 2007, a small portion of our sales are now
denominated in Canadian dollars. As our sales in currencies other than the U.S. dollar increase, our exposure to foreign currency fluctuations may increase.

In addition, changes in exchange rates also may affect the end-user prices of our products compared to those of our foreign competitors, who may be selling their products based on local currency pricing.
These factors may make our products less competitive in some countries.

If the U.S. dollar uniformly increased or decreased
in strength by 10% relative to the currencies in which our sales were denominated, our net income would have correspondingly increased or decreased by an immaterial amount for the nine months ended September 30, 2009. Our interest income is
sensitive to changes in the general level of interest rates in the U.S. However, because current market conditions have resulted in historically low rates of return on our investments, a hypothetical decrease 10% in market interest rates would not
result in a material decrease in interest income earned on investments held at September 30, 2009.

When able, we invest
excess cash in bank money-market funds or discrete short-term investments. The fair value of short-term investments and cash equivalents (investments) is sensitive to changes in the general level of interest rates in the U.S., and the
fair value of these investments will fall if market interest rates increase. However, since we generally have the ability to hold these investments to maturity, these declines in fair value may never be realized. If market interest rates were to
increase by 10% from levels at September 30, 2009, the fair value of our investments would decline by an immaterial amount.

All of the potential changes noted above are based on sensitivity analyses performed on our financial position as of September 30, 2009. Actual results may differ as our analysis of the effects of changes in interest rates does not
account for, among other things, sales of securities prior to maturity and repurchase of replacement securities, the change in mix or quality of the investments in the portfolio, and changes in the relationship between short-term and long-term
interest rates.

|ITEM 4. | Controls and Procedures
|------- | -----------------------

Evaluation of Disclosure Controls and Procedures

Under the rules of the Securities and Exchange
Commission, disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act of 1934 is
recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission. Disclosure controls and procedures include, without limitation, controls and procedures designed to
ensure that information required to be disclosed by us in our reports that we file or submit under the Securities Exchange Act of 1934 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.

Our management, with the participation of
our chief executive officer and our chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2009. Our chief executive officer and chief financial officer determined that as of
September 30, 2009 our disclosure controls and procedures were effective for the purpose set forth above.

Changes
in Internal Control over Financial Reporting

Under the rules of the Securities and Exchange Commission, internal
control over financial reporting is defined as a process designed by, or under the supervision of, an issuers principal executive and principal financial officers, and effected by the issuers board of directors, management and
other personnel, to provide reasonable assurances regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

There was no change in our internal control over financial reporting that occurred during the fiscal quarter ended September 30, 2009,
that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION



|ITEM 1. | Legal Proceedings
|------- | -----------------

We may
from time to time become a party to various legal proceedings or claims that arise in the ordinary course of business. Our management reviews these matters if and when they arise and believes that the resolution of any of these matters will not have
a significant adverse effect on our financial condition.



|ITEM 1A. | Risk Factors
|-------- | ------------

We have completed a
number of acquisitions and expect to complete additional acquisitions in the future. There are numerous risks associated with acquisitions and we may not achieve the expected benefit of any of our acquisitions

Our acquisitions of products, technology assets, or businesses may have a negative impact on our business if we fail to achieve the
anticipated financial, strategic, and other benefits of acquisitions or investments, and our operating results may suffer because of this.

We acquired intellectual property assets and technology patents from Pemstar Pacific Consultants during 2002, Neometrics Inc. and affiliated entities in 2003; Fischer-Zoth in 2004, Bio-logic, Deltamed,
and Olympic Medical, and certain assets of Nascor in 2006, Xltek in 2007, Sonamed, Schwarzer Neurology, and Neurocom in 2008, and Hawaii Medical and Alpine Biomed in 2009.

We expect to continue to pursue opportunities to acquire other businesses in future periods. The acquisitions that we have completed may not
result in improved operating results for us, or in our achieving a financial condition superior to that which we would have achieved had we not completed them. Our results of operations may be adversely impacted by costs associated with our
acquisitions, including one-time charges associated with restructurings or in-process research and development assets. Our acquisitions could fail to produce the benefits that we anticipate, or could have other adverse effects that we currently do
not foresee. In addition, some of the assumptions that we have relied upon, such as achievement of operating synergies, may not be realized. In this event, one or more of the acquisitions could result in reduced earnings of Natus as compared to the
earnings that would have been achieved by Natus if the acquisition had not occurred.

We have incurred indebtedness to fund some of our acquisitions. The use of debt to fund our
acquisitions may have an adverse impact on our liquidity and cause us to place more reliance on cash flow from operations for our liquidity. If our cash flow from operations is not sufficient for our needs, our business could be adversely affected.
If we are required to seek additional external financing to support our need for cash to fund future acquisitions, we may not have access to financing on terms that are acceptable to us, or at all. Alternatively, we may feel compelled to access
additional financing on terms that are dilutive to existing holders of our common stock or that include covenants that restrict our business, or both. If the recent lack of liquidity in credit markets persists into the future, our ability to obtain
debt financing for future acquisitions may be impaired.

If we fail to successfully manage the combined operations of Natus
and the businesses we have acquired, we may not realize the potential benefits of the acquisition. Our corporate headquarters are located in San Carlos, California. We also have the following operating divisions: Bio-logic in Illinois, Olympic in
Washington, Neurocom in Oregon, Neometrics in New York, Xltek in Ontario, Canada, Deltamed in France, and Fischer-Zoth, IT Med and Schwarzer Neurology in Germany. If we fail to manage these disparate operations effectively, our results of operations
could be harmed, employee morale could decline, key employees could leave, and customers could cancel existing orders or choose not to place new ones. In addition, we may not achieve the synergies or other benefits of these and future acquisitions
that we anticipate. We may encounter the following additional difficulties, costs, and delays involved in integrating and managing these operations, and the operations of companies we may acquire:



| |  |  | Failure of customers to continue using the products and services of the combined company;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | Failure to successfully develop the acquired technology into the desired products or enhancements;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | Assumption of unknown liabilities;
| | - |  | ----------------------------------



| |  |  | Failure to understand and compete effectively in markets and with products or technologies with which we have limited previous experience;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Impairment charges incurred to write down the carrying amount of intangible assets, including goodwill, generated as a result of the acquisition;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Decreased liquidity, restrictive bank covenants, and incremental financing costs associated with debt we may incur to complete future acquisitions;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Challenges in integrating the reporting and control systems of acquired businesses, particularly in those acquisitions where we acquire divisions,
product lines, or assets of other companies for which the former owner provided these functions; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Diversion of the attention of management from other ongoing business concerns.
| | - |  | ------------------------------------------------------------------------------

Our acquisitions of products, technology assets, or businesses may have a negative impact on our business if we fail to achieve the
anticipated financial, strategic and other benefits of acquisitions or investments, and our operating results may suffer because of this.

Adverse economic conditions in markets in which we operate may harm our business

Unfavorable changes in U.S.
and international economic environments may adversely affect our business and financial results. For example, economic conditions in the countries in which we operate and sell products have recently become more negative and global financial markets
have experienced volatility and declines since the third quarter of 2008. These conditions stem from slower economic activity, adverse credit conditions, and numerous other factors, and we are unable to foresee when, or if, these factors might
return to more normal levels. During challenging economic times, and in tight credit markets, our customers may delay or reduce capital expenditures. These conditions began to adversely affect our operating results in December 2008 and continued to
have a significant impact in the first nine months of 2009 and could continue to result in reductions in sales of our products, longer sales cycles, difficulties in collection of accounts receivable, slower adoption of new technologies, and
increased price competition. In addition, these factors have caused us to be more cautious in evaluating potential acquisition opportunities, which could hinder our ability to grow through acquisition while these conditions persist.

Demand for some of our products depends on the capital spending policies of our customers, and changes in
these policies could harm our business

A majority of customers for our products are hospitals, physician offices, and
clinics. Many factors, including public policy spending provisions, available resources, and economic cycles have a significant effect on the capital spending policies of these entities and the amount that they can spend on our products. If one or
more of these factors limit the capital spending of our customers, they will be less likely to purchase new equipment from us or to upgrade to any of our newer equipment products. We believe that the recent lack of liquidity in credit markets,
increasing unemployment, and additional effects of the uncertainty in economic conditions worldwide, have had an adverse effect on the spending patterns of our customers and may continue to have such an effect in future periods. This, in turn, can
have a significant adverse effect on our operating results and financial position.

Our growth in recent years has depended substantially
on the completion of acquisitions and we may not be able to complete acquisitions of this nature or of a relative size in the future to support a similar level of growth

The acquisitions that we have completed have been the primary source of our growth in revenue in recent years. We expend considerable effort
in seeking to identify attractive acquisition candidates and, upon doing so, to convince the potential target to consider a sale to us and, ultimately, to negotiate mutually agreeable acquisition terms. If we are not successful in these efforts in
the future, our growth rate will not increase at a rate corresponding to that which we have achieved in recent years. Further, as we grow larger it will be necessary to complete the acquisition of larger companies and product lines to support a
growth similar to that which we have achieved in the past. The market for attractive acquisitions is competitive and others with greater financial resources than we have may be better positioned than we are to acquire desirable targets. Further, we
may not be able to negotiate acquisition terms with target companies that will allow us to achieve positive financial returns from the transaction.

Future changes in technology or market conditions could result in adjustments to our recorded asset balance for intangible assets, including goodwill, resulting in additional charges that could significantly impact our operating results

Our balance sheet includes significant intangible assets, including goodwill and other acquired intangible assets. The
determination of related estimated useful lives and whether these assets are impaired involves significant judgments. Our ability to accurately predict future cash flows related to these intangible assets might be hindered by events over which we
have no control. Due to the highly competitive nature of the medical device industry, new technologies could impair the value of our intangible assets if they create market conditions that adversely affect the competitiveness of our products. We
test our intangible assets, including goodwill, in the fourth quarter of each year, but we may test more frequently if there is a change in circumstances that indicates that the carrying value of these assets may be impaired. Any future
determination that these assets are carried at greater than their fair value could result in substantial impairment charges, which could significantly impact our operating results.

Our acquisitions have included in-process research and development assets (IPR&D assets) from which we hope to generate future cash flows; our results of operations could be adversely
affected if we are unable to bring these assets to market

Through our acquisitions of other businesses, we have acquired
IPR&D assets from which we hope to generate future cash flows. There is inherent risk in bringing these IPR&D assets to market and we may be unable to realize the full value we have assigned to them. We may be unable to complete the
development of these IPR&D assets in a timely manner, or we may encounter technological difficulties that prevent us from completing their development. If we are unable to derive future revenue from our IPR&D assets, our results of
operations could be adversely impacted.

We may not be able to preserve the value of our intellectual property because we may not be able
to protect access to it or we may lose our intellectual property rights due to expiration of our licenses or patents

If
we fail to protect our intellectual property rights or if our intellectual property rights do not adequately cover the technology we employ, other medical device companies could sell products with features similar to ours, and this could reduce
demand for our products. We protect our intellectual property through a combination of patent, copyright, trade secret and trademark laws. Despite our efforts to protect our proprietary rights, others may attempt to copy or otherwise improperly
obtain and use our products or technology. Policing unauthorized use of our technology is difficult and expensive, and we cannot be certain that the steps we have taken will prevent misappropriation. Our means of protecting our proprietary rights
may be inadequate. Enforcing our intellectual property rights could be costly and time consuming and may divert our managements attention and resources. Failing to enforce our intellectual property rights could also result in the loss of those
rights.

If health care providers are not adequately reimbursed for procedures conducted with our devices or
supplies, or if reimbursement policies change adversely, we may not be successful marketing and selling our products or technologies

Clinicians, hospitals, and government agencies are unlikely to purchase our products if clinicians are not adequately reimbursed for the procedures conducted with our devices or supplies. Unless a
sufficient amount of conclusive, peer-reviewed clinical data about our products has been published, third-party payors, including insurance companies and government agencies, may refuse to provide reimbursement. Furthermore, even if reimbursement is
provided, it may not be adequate to fully compensate the clinicians or hospitals. Some third-party payors may impose restrictions on the procedures for which they will provide reimbursement. If health care providers cannot obtain sufficient
reimbursement from third-party payors for our products or the screenings conducted with our products, we may not achieve significant market acceptance of our products. Acceptance of our products in international markets will depend upon the
availability of adequate reimbursement or funding within prevailing health care payment systems. Reimbursement, funding, and health care payment systems vary significantly by country. We may not obtain approvals for reimbursement in a timely manner
or at all.

Adverse changes in reimbursement policies in general could harm our business. We are unable to predict
changes in the reimbursement methods used by third-party health care payors, particularly those in countries and regions outside the U.S. For example, some payors are moving toward a managed care system in which providers contract to provide
comprehensive health care for a fixed cost per person. In a managed care system the cost of our products may not be incorporated into the overall payment for patient care or there may not be adequate reimbursement for our products separate from
reimbursement for other procedures.

If we fail in our efforts to educate clinicians, government agency personnel, and third-party payors
on the effectiveness of our products, we may not achieve future sales growth

It is critical to the success of our sales
efforts that we educate a sufficient number of clinicians, hospital administrators, and government agencies about our products and the costs and benefits of their use. The commercial success of our products depends upon clinician, government agency
and other third-party payor confidence in the economic and clinical benefits of our products as well as their comfort with the efficacy, reliability, sensitivity and specificity of our products. We believe that clinicians will not use our products
unless they determine, based on published peer-reviewed journal articles and experience, that our products provide an accurate and cost-effective alternative to other means of testing or treatment. Our customers may choose to use competitive
products, which may be less expensive or may provide faster results than our devices. Clinicians are traditionally slow to adopt new products, testing practices and clinical treatments, partly because of perceived liability risks and the uncertainty
of third-party reimbursement. If clinicians, government agencies and hospital administrators do not adopt our products, we may not maintain profitability. Factors that may adversely affect the medical communitys acceptance of our products
include:



| |  |  | Publication of clinical study results that demonstrate a lack of efficacy or cost-effectiveness of our products;
| | - |  | ----------------------------------------------------------------------------------------------------------------



| |  |  | Changing governmental and physician group guidelines;
| | - |  | -----------------------------------------------------



| |  |  | Actual or perceived performance, quality, price, and total cost of ownership deficiencies of our products relative to other competitive products;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our ability to maintain and enhance our existing relationships and to form new relationships with leading physicians, physician organizations,
hospitals, state laboratory personnel, and third-party payors;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Changes in state and third-party payor reimbursement policies for our products; and
| | - |  | -----------------------------------------------------------------------------------



| |  |  | Repeal of laws requiring universal newborn hearing screening and metabolic screening.
| | - |  | -------------------------------------------------------------------------------------

Increased sales through group purchasing organizations and sales to high volume purchasers may reduce our average selling prices, which would reduce our
revenue and gross profits

We have entered, and expect in the future to enter into agreements with customers who purchase
high volumes of our products. Our agreements with these customers may contain discounts from our normal selling prices and other special pricing considerations, which could cause our revenue and profits to decline. In addition, we have entered into
agreements to sell our products to members of GPOs, which negotiate volume purchase prices for medical devices and supplies for member hospitals, group practices and other clinics. While we make sales directly to GPO members, the GPO members receive
volume discounts from our normal selling price and may receive other special pricing considerations from us. Sales to members of all GPOs accounted for approximately 31%, 35%

##### Table of Contents

and 31% of our total revenue during 2008, 2007 and 2006, respectively, and sales to members of one GPO, Novation LLC, accounted for approximately 10%, 9% and 12% of our total revenue in 2008,
2007 and 2006, respectively. Other of our existing customers may be members of GPOs with which we do not have agreements. Our sales efforts through GPOs may conflict with our direct sales efforts to our existing customers. If we enter into
agreements with new GPOs and some of our existing customers begin purchasing our products through those GPOs, our revenue and profits could decline.

Our markets are very competitive and in the United States we sell certain of our products in a mature market

We face competition from other companies in all of our product lines. Our competitors range from small, privately-held companies to multinational corporations and their product offerings vary in scope and breadth. We do not believe that any
single competitor is dominant in any of our product lines.

The markets for certain of our products in the U.S., including the
newborn hearing screening and EEG monitoring markets, are mature and we are unlikely to see significant growth for such products in the U.S. In the U.S. we derive a significant portion of our revenue from the sale of disposable supplies that are
used with our hearing screening devices. Because these disposable supply products can generate high margins, we expect that our products, particularly our hearing screening disposable supply products, could face increasing competition, including
competitors offering lower prices, which could have an adverse affect on our revenue and margins.

We believe that our primary
competitive strengths relate to the functionality and reliability of our products, our recognized brands, and our developed sales channels. Our competitors may have certain competitive advantages, which include the ability to devote greater
resources to the development, promotion, and sale of their products. Consequently, we may need to increase our efforts, and related expenses for research and development, marketing, and selling to maintain or improve our position.

We expect recurring sales to our existing customers to generate a majority of our revenue in the future, and if our existing customers do
not continue to purchase products from us, our revenue may decline.

Our operating results may decline if we do not succeed in developing,
acquiring and marketing additional products or improving our existing products

We intend to develop additional products
and technologies, including enhancements of existing products, for the screening, detection, treatment, monitoring and tracking of common medical ailments. Developing new products, and improving our existing products, to meet the needs of current
and future customers requires significant investments in research and development. If we fail to successfully sell new products, update our existing products, or timely react to changes in technology, our operating results may decline as our
existing products reach the end of their commercial life cycles.

Our plan to expand our international operations will result in increased
costs and is subject to numerous risks; if our efforts are not successful, this could harm our business

We have expanded
our international operations through acquisitions and plan to expand our international sales and marketing efforts to increase sales of our products in foreign countries. We may not realize corresponding growth in revenue from growth in
international unit sales, due to the lower average selling prices we receive on sales outside of the U.S. Even if we are able to successfully expand our international selling efforts, we cannot be certain that we will be able to create or increase
demand for our products outside of the U.S. Our international operations are subject to other risks, which include:



| |  |  | Impact of adverse conditions including possible recessions in economies outside the U.S.;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | Political and economic instability, including instability related to war and terrorist attacks in the U.S. and abroad;
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | Contractual provisions governed by foreign law, such as local law rights to sales commissions by terminated distributors;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | Decreased health care spending by foreign governments that would reduce international demand for our products;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | Continued strengthening of the U.S. dollar relative to foreign currencies that could make our products less competitive because most of our
international sales are denominated in U.S. dollars;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



29

##### Table of Contents

| |  |  | Greater difficulty in accounts receivable collection and longer collection periods;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | Difficulties of staffing and managing foreign operations;
| | - |  | ---------------------------------------------------------



| |  |  | Reduced protection for intellectual property rights in some countries and potentially conflicting intellectual property rights of third parties under
the laws of various foreign jurisdictions;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Difficulty in obtaining and maintaining foreign regulatory approval; and
| | - |  | ------------------------------------------------------------------------



| |  |  | Attitudes by clinicians, and cost reimbursement policies, towards use of disposable supplies that are potentially unfavorable to our business.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------

In particular, our international sales could be adversely affected by a strengthening of the U.S. dollar
relative to other foreign currencies, which makes our products more costly to international customers to whom sales are denominated in U.S. dollars.

Our operating results may suffer because of our exposure to foreign currency exchange rate fluctuations

While
substantially all of the sales contracts of Natus Medical Incorporated and our North American subsidiaries provide for payment in U.S. dollars, substantially all of the revenue and expenses of our subsidiaries outside of North America are
denominated in the local currency. To date we have executed only limited foreign currency contracts to hedge these currency risks. Our future revenue and expenses may be subject to volatility due to exchange rate fluctuations that could result in
foreign exchange gains and losses associated with foreign currency transactions and the translation of assets and liabilities denominated in foreign currencies.

Substantially all our sales from our U.S. operations to our international distributors also provide for payment in U.S. dollars. A strengthening of the U.S. dollar relative to other foreign currencies
could increase the effective cost of our products to our international distributors as their functional currency is typically not the U.S. dollar. This could have a potential adverse effect on our ability to increase or maintain average selling
prices of our products to our foreign-based customers.

If guidelines mandating universal newborn hearing screening do not continue to
develop in foreign countries and governments do not mandate testing of all newborns as we anticipate, or if those guidelines have a long phase-in period, our revenue may be adversely impacted

We estimate that approximately 95% of the children born in the U.S. are currently being tested for hearing impairment prior to discharge
from the hospital. To date, there has been only limited adoption of newborn hearing screening prior to hospital discharge by foreign governments, and when newborn hearing screening programs are enacted by foreign governments there can be a phase-in
period spanning several years. The widespread adoption of guidelines depends, in part, on our ability to educate foreign government agencies, neonatologists, pediatricians, third-party payors, and hospital administrators about the benefits of
universal newborn hearing screening as well as the use of our products to perform the screening and monitoring. Our revenue from our newborn hearing screening product lines may not grow if foreign governments do not require universal newborn hearing
screening prior to hospital discharge, if physicians or hospitals are slow to comply with those guidelines, or if governments provide for a lengthy phase-in period for compliance.

Because we rely on distributors or sub-distributors to sell our products in most of our markets outside of the U.S., our revenue could decline if our existing distributors reduce the volume of
purchases from us, or if our relationship with any of these distributors is terminated

We currently rely on our
distributors or sub-distributors for a majority of our sales outside the U.S. Some distributors also assist us with regulatory approvals and education of clinicians and government agencies. We intend to continue our efforts to increase our sales in
Europe, Japan, and other developed countries. If we fail to sell our products through our international distributors, we would experience a decline in revenues unless we begin to sell our products directly in those markets. We cannot be certain that
we will be able to attract new international distributors to market our products effectively or provide timely and cost-effective customer support and service. Even if we are successful in selling our products through new distributors, the rate of
growth of our revenue could be harmed if our existing distributors do not continue to sell a large dollar volume of our products. None of our existing distributors are obligated to continue selling our products.

We may be subject to foreign laws governing our relationships with our international distributors. These laws may require us to make
payments to our distributors if we terminate our relationship for any reason, including for cause. Some countries require termination payments under local law or legislation that may supersede our contractual relationship with the distributor. Any
required payments would adversely affect our operating results.

If we lose our relationship with any supplier of key product components or our relationship with a
supplier deteriorates or key components are not available in sufficient quantities, our manufacturing could be delayed and our business could suffer

We contract with third parties for the supply of some of the components used in our products and the production of our disposable products. Some of our suppliers are not obligated to continue to supply
us. We have relatively few sources of supply for some of the components used in our products and in some cases we rely entirely on sole-source suppliers. In addition, the lead-time involved in the manufacturing of some of these components can be
lengthy and unpredictable. If our suppliers become unwilling or unable to supply us with components meeting our requirements, it might be difficult to establish additional or replacement suppliers in a timely manner, or at all. This would cause our
product sales to be disrupted and our revenue and operating results to suffer.

Replacement or alternative sources might not
be readily obtainable due to regulatory requirements and other factors applicable to our manufacturing operations. Incorporation of components from a new supplier into our products may require a new or supplemental filing with applicable regulatory
authorities and clearance or approval of the filing before we could resume product sales. This process may take a substantial period of time, and we may not be able to obtain the necessary regulatory clearance or approval. This could create supply
disruptions that would harm our product sales and operating results.

We depend upon key employees in a competitive market for skilled
personnel, and, without additional employees, we cannot grow or maintain profitability

Our products and technologies are
complex, and we depend substantially on the continued service of our senior management team. The loss of any of our key employees could adversely affect our business and slow our product development process. Our future success also will depend, in
part, on the continued service of our key management personnel, software engineers, and other research and development employees and our ability to identify, hire, and retain additional personnel, including customer service, marketing, and sales
staff. Hiring research and development, engineering, sales, marketing and customer service personnel in our industry is very competitive due to the limited number of people available with the necessary technical skills and understanding of our
product technologies. We may be unable to attract and retain personnel necessary for the development of our business.

Our ability to
market and sell products depends upon receipt of domestic and foreign regulatory approval of our products and manufacturing operations. Our failure to obtain or maintain regulatory approvals and compliance could negatively affect our business

Our products and manufacturing operations are subject to extensive regulation in the United States by the FDA and by similar
regulatory agencies in many other countries in which we do business. Our products are classified as medical devices. Medical devices are subject to extensive regulation by the FDA pursuant to regulations that are wide ranging and govern, among other
things: design and development; manufacturing and testing; labeling; storage and record keeping; advertising, promotion, marketing, sales distribution and export; and surveillance and reporting of deaths or serious injuries.

Unless an exemption applies, each medical device that we propose to market in the U.S. must first receive one of the following types of FDA
premarket review authorizations:



| |  |  | Clearance via Section 510(k) of the Food, Drug, and Cosmetics Act of 1938, as amended; or
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | Premarket approval via Section 515 of the Food, Drug, and Cosmetics Act if the FDA has determined that the medical device in question poses a
greater risk of injury.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------

The FDA will clear marketing of a medical device through the 510(k) process if it
is demonstrated that the new product is substantially equivalent to other 510(k)-cleared products. The premarket approval application process is much more costly, lengthy and uncertain than the 510(k) process, and must be supported by extensive data
from preclinical studies and human clinical trials. The FDA may not grant either 510(k) clearance or premarket approval for any product we propose to market. Further, any modification to a 510(k)-cleared device that could significantly affect its
safety or effectiveness, or that would constitute a major change in its intended use, design or manufacture, requires a new 510(k) clearance or, possibly, approval of a premarket approval application. The FDA requires every manufacturer to make this
determination in the first instance, but the FDA may review any manufacturers decision. If the FDA requires us to seek 510(k) clearance or premarket approval for modification of a previously cleared product for



31



---

##### Table of Contents

which we have concluded that new clearances or approvals are unnecessary, we may be required to cease marketing or to recall the modified product until we obtain clearance or approval, and we may
be subject to significant regulatory fines or penalties. Further, our products could be subject to recall if the FDA determines, for any reason, that our products are not safe or effective.

Delays in receipt or failure to receive clearances or approvals, the loss of previously received clearances or approvals, or the failure to
comply with existing or future regulatory requirements could adversely impact our operating results. If the FDA finds that we have failed to comply with these requirements, the Agency can institute a wide variety of enforcement actions, ranging from
a public warning letter to more severe sanctions such as:



| |  |  | Fines, injunctions and civil penalties;
| | - |  | ---------------------------------------



| |  |  | Recall or seizure of our products;
| | - |  | ----------------------------------



| |  |  | Issuance of public notices or warnings;
| | - |  | ---------------------------------------



| |  |  | Imposition of operating restrictions, partial suspension, or total shutdown of production;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | Refusal of our requests for Section 510(k) clearance or premarket approval of new products;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | Withdrawal of Section 510(k) clearance or premarket approvals already granted; or
| | - |  | ---------------------------------------------------------------------------------



| |  |  | Criminal prosecution.
| | - |  | ---------------------

Domestic regulation of our products and manufacturing operations, other than that which is administered by the FDA, includes the Environmental Protection Act, the Occupational Safety and Health Act, and
state and local counterparts to these Acts.

Our business would be harmed if the FDA determines that we have failed to comply with
applicable regulations governing the manufacture of our products and/or we do not pass an inspection

We and our suppliers
are required to demonstrate and maintain compliance with the FDAs Quality System Regulation. The Quality System Regulation sets forth the FDAs requirements for good manufacturing practices of medical devices and includes requirements
for, among other things, the design, testing, production processes, controls, quality assurance, labeling, packaging, storage and shipping of such products. In addition, we and our suppliers must engage in extensive recordkeeping and reporting and
must make available our manufacturing facility and records for periodic unscheduled inspections by federal, state and foreign agencies, including the FDA. We cannot assure you that we and our suppliers are or will continue to be in full compliance
with the Quality System Regulation, and that we will not encounter any manufacturing difficulties.

Failure of our third party
suppliers and manufacturers or us to comply with applicable regulations could result in sanctions being imposed on us, including, among other things, fines, injunctions, civil penalties, failure of regulatory authorities to grant marketing approval
of our products, delays, suspension or withdrawal of approvals, seizures or recalls of products and manufacturing restrictions, any of which could harm our business.

Our Olympic Cool-Cap product is subject to greater products liability exposure and FDA regulation

The FDA classifies medical devices into one of three classes, depending on the degree of risk associated with each medical device and the extent of controls that are needed to ensure safety and
effectiveness. Devices deemed to pose lower risk are placed in either class I or class II. Devices deemed by the FDA to pose the greatest risk, such as life-sustaining, life supporting or implantable devices, or a device deemed to not be
substantially equivalent to a previously cleared 510(k) device are placed in class III, and generally require premarket approval from the FDA before they may be marketed.

In December 2006 we received premarket approval from the FDA to market the Olympic Cool-Cap, a product designed to lower the cerebral temperature of newborns born with a particular medical condition. This
product is a class III minimally invasive medical device, and as such we may be subject to an increased product liability risk relative to our other class I and class II non-invasive products. In addition, this type of product is subject to
greater FDA oversight than our other products and there is greater risk that sales of the product could be interrupted due to the premarket approval processes of the FDA and other regulatory bodies.

Our business may suffer if we are required to revise our labeling or promotional materials, or if the FDA
takes an enforcement action against us for off-label uses

We are prohibited by the FDA from promoting or advertising our
medical device products for uses not within the scope of our clearances or approvals, or from making unsupported promotional claims about the benefits of our products. If the FDA determines that our claims are outside the scope of our clearances, or
are unsupported, it could require us to revise our promotional claims or take enforcement action against us. If we were subject to such an action by the FDA, our sales could be delayed, our revenue could decline, and our reputation among clinicians
could be harmed. Likewise, if we acquire new products, either through the purchase of products, technology assets, or businesses, that are subsequently deemed to have inadequate supporting data, we may be required to (i) obtain adequate data,
which could be costly and impede our ability to market these products, or (ii) modify the labeling on these products, which could impair their marketability, as described above.

If we fail to comply with healthcare regulations, we could face substantial penalties and our business, operations and financial condition could be adversely affected.

We do not provide healthcare services, control the referral of patients for healthcare services, nor bill Medicare, Medicaid or other
third-party payors; however, due to the breadth of many healthcare laws and regulations, we could be subject to healthcare fraud regulation and enforcement by both the federal government and the states in which we conduct our business. The laws that
may affect our ability to operate include: (i) the federal healthcare programs Anti-Kickback Law, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or
indirectly, in exchange for or to induce either the referral of an individual for, or the purchase, order or recommendation of, any good or service for which payment may be made under federal healthcare programs such as Medicare or Medicaid,
(ii) federal false claims laws which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payors that are false or
fraudulent, and which may apply to entities like us which provide coding and billing advice to customers, and/or (iii) state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may apply to items
or services reimbursed by any third-party payor, including commercial insurers, many of which differ from their federal counterparts in significant ways, thus complicating compliance efforts.

If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we
may be subject to penalties, including civil and criminal penalties, damages, fines and the curtailment or restructuring of our operations. Any penalties, damages, fines, curtailment or restructuring of our operations could adversely affect our
ability to operate our business and our financial results. The risk of our being found in violation of these laws is increased by the fact that their provisions are open to a variety of interpretations. Any action against us for violation of these
laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our managements attention from the operation of our business.

Our operating results would suffer if we were subject to a protracted infringement claim

The medical technology industry is characterized by a substantial amount of litigation and related administrative proceedings regarding patents and intellectual property rights. We expect that medical
screening and diagnostic products may become increasingly subject to third-party infringement claims as the number of competitors in our industry segment grows and the functionality of products in different industry segments overlap. Third parties
such as individuals, educational institutions or other medical device companies may claim that we infringe their intellectual property rights. Any claims, with or without merit, could have any of the following negative consequences:



| |  |  | Result in costly litigation and damage awards;
| | - |  | ----------------------------------------------



| |  |  | Divert our managements attention and resources;
| | - |  | ------------------------------------------------



| |  |  | Cause product shipment delays or suspensions; or
| | - |  | ------------------------------------------------



| |  |  | Require us to seek to enter into royalty or licensing agreements.
| | - |  | -----------------------------------------------------------------

A successful claim of infringement against us could result in a substantial damage award and materially harm our financial condition. Our
failure or inability to license the infringed or similar technology, or design and build non-infringing products, could prevent us from selling our products and adversely affect our business and financial results.

We license intellectual property rights from third parties and would be adversely affected if our licensors do not appropriately defend their proprietary
rights or if we breach any of the agreements under which we license commercialization rights to products or technology from others

We license rights from third parties for products and technology that are important to our business. If our licensors are unsuccessful in asserting and defending their proprietary rights, including patent rights and trade secrets, we may
lose the competitive

advantages we have through selling products that we license from third parties. Additionally, if it is found that our licensors infringe on the proprietary rights of others, we may be prohibited
from marketing our existing products that incorporate those proprietary rights. Under our licenses, we are subject to commercialization and development, sublicensing, royalty, insurance and other obligations. If we fail to comply with any of these
requirements, or otherwise breach a license agreement, the licensor may have the right to terminate the license in whole or to terminate the exclusive nature of the license.

Product liability suits against us could result in expensive and time consuming litigation, payment of substantial damages, and an increase in our insurance rates

The sale and use of our products could lead to the filing of a product liability claim by someone claiming to have been injured using one of
our products or claiming that one of our products failed to perform properly. A product liability claim could result in substantial damages and be costly and time consuming to defend, either of which could materially harm our business reputation or
financial condition. Our product liability insurance may not protect our assets from the financial impact of defending a product liability claim. Any product liability claim brought against us, with or without merit, could increase our product
liability insurance rates or prevent us from securing any coverage in the future.

We have experienced seasonality in the sale of our
products

We experience seasonality in our revenue. For example, our sales typically decline from our fourth fiscal
quarter to our first fiscal quarter, due to patterns in the capital budgeting and purchasing cycles of our current and prospective customers, many of which are government agencies. We may also experience declining sales in the third fiscal quarter
due to summer holiday and vacation schedules. We anticipate that we will continue to experience these seasonal fluctuations, which may lead to fluctuations in our quarterly operating results. We believe that you should not rely on our results of
operations for interim periods as an indication of our expected results in any future period.

We have initiated changes to our information
systems that could disrupt our business and our financial results.

We plan to continuously improve our enterprise
resource planning, customer relationship management, and document lifecycle management systems to support the form, functionality, and scale of our business. These types of transitions frequently prove disruptive to the underlying business of an
enterprise and may cause us to incur higher costs than we anticipate. Failure to manage a smooth transition to the new systems and the ongoing operations and support of the new systems could materially harm our business operations.

For example, we are currently in the process of implementing the rollout of an enterprise resource planning application
(ERP) in our North American operating divisions. Until we have completed the ERP implementation, we will be dependent on multiple platforms. We may experience difficulties in implementing the ERP and we may fail to gain the efficiencies
the implementation is designed to produce. The implementation could also be disruptive to our operations, including the ability to timely ship and track product orders to customers, project inventory requirements, manage our supply chain and
otherwise adequately service our customers.
