SIRONA DENTAL SYSTEMS, INC. AND SUBSIDIARIES

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. General

The Company and its Operations

Sirona Dental Systems, Inc. (Sirona or the Company) is the leading manufacturer of high-quality, technologically
advanced dental equipment, and is focused on developing, manufacturing and marketing innovative systems and solutions for dentists around the world. We offer a broad range of products across all major segments of the dental technology market
including CEREC and our other CAD/CAM systems, digital intra oral and 2D and 3D panoramic imaging systems, treatment centers and instruments. The Company acquired Schick Technologies, Inc. (Schick) in 2006, in a transaction accounted for
as a reverse acquisition, further expanding our global presence and product offerings and strengthening our research and development capabilities. Sirona has served equipment dealers and dentists worldwide for more than 130 years. The
Companys headquarters are located in Long Island City, New York with its primary facility located in Bensheim, Germany, as well as other support, manufacturing, assembling and sales and service facilities located elsewhere in the world.

Basis of Presentation

These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally
accepted in the United States (U.S. GAAP). Preparation of the interim financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions related to the reported amounts of assets and liabilities and
the disclosure of contingent assets and liabilities as at the reporting date and the reported amounts of revenues and expenses for the interim period. Actual results could differ from those estimates. Certain information and footnote disclosures
normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information not
misleading. The year-end condensed consolidated balance sheet data was derived from the audited consolidated financial statements, but does not include all disclosures required by U.S. GAAP. These consolidated financial statements should be read in
conjunction with the Consolidated Financial Statements and the Notes thereto included in the Companys Annual Report on Form 10-K for the fiscal year ended September 30, 2009.

In the opinion of management, all adjustments (consisting of those of a normal recurring nature) considered necessary to present fairly
the Companys financial position as of March 31, 2010 and September 30, 2009 and the results of operations and cash flows for the three and six months ended March 31, 2010 and 2009, respectively, as applicable to interim periods
have been made. The results of operations for the three or six months ended March 31, 2010 are not necessarily indicative of the operating results for the full fiscal year or future periods.

All amounts are reported in thousands of U.S. Dollars ($), except per share amounts or as otherwise disclosed.

Fiscal year

The
Companys fiscal year is October 1 to September 30.

Principles of consolidation

The consolidated financial statements include, after eliminating inter-company transactions and balances, the accounts of Sirona Dental
Systems, Inc. and its subsidiaries. The Company applies the equity method of accounting for investments in associated companies over which the Company has significant influence but does not have effective control.

2. Recently Issued Accounting Pronouncements

Adopted

Business Acquisitions

On October 1, 2009, the Company adopted the new accounting guidance for business combinations (SFAS No. 141
(Revised), Business Combinations (SFAS 141R)  (FASB Codification ASC 805, Business Combinations)). This guidance establishes principles and requirements for the reporting entity in a business combination, including
recognition and measurement in the financial statements of the identifiable assets acquired, the liabilities assumed, goodwill, and any noncontrolling interest in the acquiree, as well as disclosure requirements to enable financial statement users
to evaluate the nature and financial effects of the business combination. Additionally, it provides guidance for identifying a business combination, measuring the acquisition date, and defining the measurement period for adjusting provisional
amounts recorded. The implementation of this standard did not have a material impact on the Companys interim condensed consolidated financial statements.

Noncontrolling Interests

On October 1, 2009, the Company adopted the new accounting guidance for reporting a noncontrolling interest (NCI) in a
subsidiary (SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements  an amendment of ARB No. 51, (SFAS 160)  (FASB Codification ASC 810, Consolidation), which amends
Accounting Research Bulletin No. 51, Consolidated Financial Statements (ARB No. 51)). This new guidance defines a noncontrolling interest, establishes a single method of accounting for changes in a parents
ownership interest not resulting in deconsolidation, accounting for deconsolidation, and expands the disclosures of NCIs in consolidated financial statements. As a result, the Company reported NCI as a separate component of Stockholders
Equity in the Condensed Consolidated Balance Sheet. Additionally, the Company reported the portion of net income attributed to the Company and NCI separately in the Condensed Consolidated Income Statements. The portion of comprehensive income
attributed to the Company and NCI are reported separately in a Note to the consolidated financial statements. All related disclosures have been adjusted accordingly. Prior year amounts associated with NCI in the financial statements and accompanying
footnotes have been adjusted retrospectively to conform to the adoption.

Intangible Assets

On October 1, 2009, the Company adopted the new accounting guidance for determination of the useful lives of intangible assets (FASB
Staff Position (FSP) No. 142-3, Determination of the Useful Lives of Intangible Assets, (FSP 142-3)  (FASB Codification ASC 350, Intangibles  Goodwill and Other)). This new guidance amends the
factors that should be considered in developing renewal or extension assumptions used to determine the useful life of an intangible asset as well as the period of expected cash flows used to measure the fair value of intangible assets in business
combinations. The implementation of this new guidance did not have a material impact on the Companys interim condensed consolidated financial statements.

Fair Value Measurement

On October 1, 2009, the Company adopted FAS 157, Fair Value Measurements (FASB Codification ASC 820, Fair Value
Measurements and Disclosures) for non-recurring fair value measurements of non-financial assets and liabilities. The implementation of this new guidance did not have a material impact on the Companys interim condensed consolidated
financial statements.

Not yet adopted

In October 2009, the FASB issued ASU 2009-13, Multiple-Deliverable Revenue Arrangements  a consensus of the FASB Emerging Issues
Task Force, which amends the criteria for separating consideration in multiple-deliverable arrangements, establishes a selling price hierarchy for determining the selling price of a deliverable, replaces the term fair value in
the revenue allocation with selling price to clarify that the allocation of revenue is based on entity-specific assumptions rather than assumptions of a marketplace participant, replaces the residual method of
allocation with the relative selling-price method, and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables applying this method, including proportional allocation of any
discounts to each deliverable. In addition, this new guidance will require that a vendor determine its best estimate of selling price in a manner that is consistent with that used to determine the selling price of a deliverable on a standalone basis
and expands the required disclosures to provide information about the significant judgments made and changes to those judgments and about how the application of the relative selling-price method affects the timing or amount of revenue recognition.
ASU 2009-13 is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010, which corresponds to the Companys fiscal year beginning October 1, 2010. The
Company is evaluating the potential impact of adoption.

In October 2009, the FASB issued ASU 2009-14, Certain Revenue
Arrangements that Include Software Elements  a consensus of the FASB Emerging Issues Task Force, which changes the accounting model for revenue arrangements that include both tangible products and software elements. This new guidance
removes from the scope of the software revenue recognition guidance in ASC 985-605, Software Revenue Recognition, those tangible products containing software components and nonsoftware components that function together to deliver the tangible
products essential functionality. In addition, this guidance requires that hardware components of a tangible product containing software components always be excluded from the software revenue recognition guidance as well as provides further
guidance on determining which software, if any, relating to the tangible product also would be excluded from the scope of software revenue recognition guidance. The guidance further identifies specific factors in determining whether the tangible
product contains software that works together with the nonsoftware components of the tangible product to deliver the tangible products essential functions. Guidance is also provided on how a vendor should allocate arrangement consideration to
deliverables in an arrangement containing both tangible products and software. The disclosures mandated in ASU 2009-13 are also required by this new guidance. ASU 2009-14 is effective prospectively for revenue arrangements entered into or materially
modified in fiscal years beginning on or after June 15, 2010, which corresponds to the Companys fiscal year beginning October 1, 2010. The Company is evaluating the potential impact of adoption.

3. Employee Share-Based Compensation

Stock compensation expense for the Companys stock option plans amounted to $4,109 and $8,048 for the three and six months ended
March 31, 2010, respectively, and $3,959 and $7,794 for the three and six months ended March 31, 2009, respectively. The fiscal 2010 expenses include the impact of previous stock options, restricted stock, and the restricted stock unit
(RSU) grants.

On December 8, 2009, the Company granted 188,000 RSUs under the Equity Incentive Plan
(the 2006 Plan). The RSUs vest over a period of four years (one third each at December 8, 2011, 2012 and 2013). The value of each RSU is determined by the closing price as of the date of grant of $34.45. The 2006 Plan provides
for granting in total up to 4,550,000 stock options, incentive stock, and RSUs to employees, directors, and consultants and received stockholder approval at the Companys Annual Meeting of Stockholders held on February 27, 2007, and
was amended on February 25, 2009. As of March 31, 2010, 1,646,358 shares were available for future grant under the 2006 Plan.

The change in the book value of goodwill and of
intangible assets from September 30, 2009 to March 31, 2010 mainly results from foreign currency fluctuations, with an impact of $47,066 on goodwill and $50,569 on intangible assets for the first half of fiscal 2010. Goodwill has also been
reduced by (i) $400 as a result of the sale of a subsidiary and (ii) $656 as a result of tax benefits received subsequent to the acquisition of Schick for options that were vested and included in the determination of purchase price at the
time of that acquisition.

Senior Term Loans

On November 22, 2006, Sirona Dental Systems, Inc. entered into a Senior Facilities Agreement (the Senior Facilities
Agreement) as original guarantor, with all significant subsidiaries of Sirona as original borrowers and original guarantors. Initial borrowings under the Senior Facilities Agreement plus excess cash were used to retire the outstanding
borrowings under the Companys previous credit facilities.

The Senior Facilities Agreement includes: (1) a term
loan A1 in an aggregate principal amount of $150 million (the tranche A1 term loan) available to Sironas subsidiary, Schick NY, as borrower; (2) a term loan A2 in an aggregate principal amount of Euro 275 million
(the tranche A2 term loan) available to Sironas subsidiary, Sirona Dental Services GmbH, as borrower; and (3) a $150 million revolving credit facility available to Sirona Dental Systems GmbH, Schick NY and Sirona Dental
Services GmbH, as initial borrowers. The revolving credit facility is available for borrowing in Euro, U.S. Dollars, Yen or any other freely available currency agreed to by the facility agent. The facilities are made available on an unsecured basis.
Subject to certain limitations, each European guarantor guarantees the performance of each European borrower, except itself, and each U.S. guarantor guarantees the performance of each U.S. borrower, except itself. There are no cross-border
guarantees since all guarantees are by entities that have the same functional currency as the currency in which the respective guaranteed borrowing is denominated.

##### Table of Contents

Each of the senior term loans are to be repaid in three annual installments beginning on
November 24, 2009 and ending on November 24, 2011. Of the amounts borrowed under the term loan facilities, 15% was due on November 24, 2009, 15% was due on November 24, 2010 and 70% is due on November 24, 2011. The senior
debt repayment tranche originally scheduled for November 24, 2009 was prepaid on May 11, 2009 in the amount of $78.6 million, and the senior debt repayment tranche originally scheduled for November 24, 2010 was prepaid on
March 31, 2010 in the amount of $78.1 million. At the Companys current Debt Cover Ratio, the facilities bear interest of Euribor, for Euro-denominated loans, and Libor for the other loans, plus a margin of 45 basis points for both.

The Senior Facilities Agreement contains a margin ratchet. Pursuant to this provision, which applies from November 24,
2007 onwards, the applicable margin will vary between 90 basis points and 45 basis points per annum according to the Companys leverage multiple (i.e. the ratio of consolidated total net debt to consolidated adjusted EBITDA as defined in the
Senior Facilities Agreement). Interest rate swaps were established for 66.6% of the interest until March 2010. These swaps expired on March 31, 2010 and were not renewed. The interest rate swaps fixed the LIBOR or EURIBOR element of
interest payable on 66.7% of the principal amount of the loans for defined twelve and thirteen month interest periods over the lifetime of the swaps, respectively. The defined interest rates fixed for each twelve or thirteen month interest period
ranged from 3.50% to 5.24%. Settlement of the swaps was required on a quarterly basis.

The Senior Facilities Agreement
contains restrictive covenants that limit Sironas ability to make loans, make investments (including in joint ventures), incur additional indebtedness, make acquisitions or pay dividends, subject to agreed-upon exceptions. The Company has
agreed to certain financial debt covenants in relation to the financing. The covenants stipulate that the Company must maintain certain ratios in respect of interest payments and defined earnings measures. If the Company breaches any of the
covenants, the loans will be become repayable on demand.

Debt issuance costs of $5.6 million were incurred in relation
to the financing in November 2006 and were capitalized as deferred charges and are amortized using the effective interest method over the term of the loan.

9. Income Taxes

For the
first half of fiscal year 2010, an estimated effective tax rate of 20% has been applied, compared to an estimated effective tax rate of 28% for the first half of fiscal year 2009 and an effective tax rate for fiscal year 2009 of 14.7%. The estimated
effective tax rate is primarily driven by the expected distribution of profits across different countries. Factors such as variances between the expected and actual distribution of profits for the remainder of the year could result in a deviation of
the actual from the estimated tax rate.

With limited exception, the Company and its subsidiaries are no longer subject to
U.S. federal, state and local or non-U.S. income tax examinations by taxing authorities for tax returns filed with respect to periods prior to fiscal 2005.

Stock options to acquire 80,250 and 1,231,950 shares
of Sironas common stock that were granted in connection with the Companys stock option plans were not included in the computation of diluted earnings per share for the three and six months ended March 31, 2010 and 2009,
respectively, because the options underlying exercise prices were greater than the average market price of Sironas common stock for the respective period.

13. Net Other Operating Income

Net other operating income for the three and six months ended March 31, 2010 was $3.4 million and $5.9 million, respectively,
compared to net other operating income/(loss) of $(0.3) million and $3.2 million, respectively, for the three and six months ended March 31, 2009. In both periods, net other operating income included $2.5 million (three months) and $5.0 million
(six months), respectively, of income resulting from the amortization of the deferred income relating to the Patterson exclusivity payment. In the three and six months ended March 31, 2010, net other operating income included a gain from the
sale of a subsidiary in Italy of $0.9 million. In the three and six months ended March 31, 2009, net other operating income included a gain from the sale of a sales and service subsidiary in Spain of $1.0 million. In the three and six months
ended March 31, 2009, net other operating income included restructuring costs of $2.8 million.

Restructuring Costs

In fiscal year 2009, we incurred restructuring costs of $8.2 million included in net other operating income for certain actions to reduce
operating costs and thereby to improve the efficiency of our organization.

As of September 30, 2009, we had accrued
restructuring costs in the amount of $4.2 million. No further restructuring costs were incurred for the three and six months ended March 31, 2010. The development of restructuring costs in the current fiscal year is presented in the following
table:

14. Derivative Instruments and Hedging Strategies

Our operations are exposed to market risks from changes in foreign currency exchange rates and interest rates. In the normal course of
business, these risks are managed through a variety of strategies, including the use of derivatives.

Interest Rate Risk

The Company is exposed to interest rate risk associated with fluctuations in the interest rates on its variable interest rate debt. In
order to manage this risk, the Company entered into interest rate swap agreements that convert the debts variable interest rate to a fixed interest rate. While these swap agreements were considered to be economic hedges, they are not
designated as hedging instruments under ASC 815.

Interest rate swaps were established for 66.6% of the interest until
March 2010. These swaps expired on March 31, 2010 and were not renewed. The interest rate swaps fixed the LIBOR or EURIBOR element of interest payable on 66.7% of the principal amount of the loans for defined twelve and thirteen month
interest periods over the lifetime of the swaps, respectively. The defined interest rates fixed for each twelve or thirteen month interest period ranged from 3.50% to 5.24%. Settlement of the swaps was required on a quarterly basis.

Foreign Currency Exposure

Although the U.S. Dollar is Sironas reporting currency, its functional currency varies depending on the country of operation.
During the periods under review, particularly the U.S. Dollar/Euro exchange rate fluctuated significantly, thereby impacting Sironas financial results.

In order to manage foreign currency exposures, the Company enters into foreign exchange forward contracts (USD, AUD, and JPY). As with
its interest rate swap instruments, the Company enters into forward contracts that are considered to be economic hedges, which are not considered hedging instruments under ASC 815.

As of March 31, 2010, these contracts had notional amounts totaling $72.7 million. These agreements are relatively short-term
(generally six months).

The fair value carrying amount of the Companys derivative instruments at March 31, 2010 is
described in Note 15 Fair Value Measurements.

The location and amount of gains and losses from the fair value changes of
derivative instruments reported in our condensed consolidated income statement were as follows:

15. Fair Value Measurements and Financial Instruments

On October 1, 2008, the Company adopted the provisions of ASC 820, Fair Value Measurements and Disclosures, for assets and
liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. ASC 820 defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly
transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities that are required to be recorded or disclosed at fair value, the Company considers the principal or most
advantageous market in which it would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as inherent risk, transfer restrictions, and the credit risk of the
Company and counterparties to the arrangement.

ASC 820 establishes a fair value hierarchy that prioritizes the inputs to
valuation techniques used to measure fair value into three levels. A financial instruments categorization within the fair value hierarchy is based upon the lowest

level of input that is available and significant to the fair value measurement. ASC 820 establishes and prioritizes the following three levels of inputs that may be used to measure fair value:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar
assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Inputs that are generally unobservable and typically reflect managements estimates of assumptions that market participants would use in
pricing the asset or liability.

Assets/Liabilities Measured at Fair Value on a Recurring Basis

The following table presents the Companys assets and liabilities related to foreign exchange contracts measured at fair value on a
recurring basis as of March 31, 2010:

In the Companys March 31, 2010 Consolidated Balance Sheet, derivative assets and
derivative liabilities are classified as prepaid expenses and other current assets and accrued liabilities and deferred income, respectively.

The Company did not elect the fair value option for any eligible financial instruments.

Fair value of financial instruments

Financial instruments consist of cash, cash equivalents, accounts receivable, accounts payable, and foreign currency forward contracts.
The carrying amounts of cash, cash equivalents, accounts receivable and accounts payable approximate their respective fair values because of the short-term nature of these items. The fair value of foreign currency forward contracts is estimated by
obtaining quotes from financial institutions.

16. Segment Reporting

The following tables reflect the results of the Companys reportable segments under the Companys management reporting system.
The segment performance measure used to monitor segment performance is gross profit (Segment Performance Measure) excluding the impact of the acquisition of control of the Sirona business by Sirona Holdings Luxco S.C.A.
(Luxco), a Luxembourg-based holding entity owned by funds managed by Madison Dearborn Partners (MDP), Beecken Petty OKeefe and management of Sirona, through a leveraged buyout transaction on June 30, 2005 (the
MDP Transaction) and the acquisition of Schick (the Exchange) in 2006. This measure is considered by management to better reflect the performance of each segment as it eliminates the need to allocate centrally incurred costs
and significant purchase accounting impacts that the Company does not believe are representative of the performance of the segments. Furthermore, the Company monitors performance geographically by region. As the Company manages its business on both
a product and a geographical basis, U.S. GAAP requires segmental disclosure based on product information.

##### Table of Contents

Reconciliation of the results of the segment performance measure to the consolidated statements of
operations

The following table and discussion provide a reconciliation of the total results of operations of the
Companys business segments under management reporting to the consolidated financial statements. The differences shown between management reporting and U.S. GAAP for the three and six month periods ended March 31, 2010 and 2009 are mainly
due to the impact of purchase accounting. Purchase accounting effects are not included in gross profit as the Company does not believe these to be representative of the performance of each segment.

Inter-segment transactions are based on amounts which management believes are approximate to the amounts of transactions with unrelated
third parties.

Overview

Sirona Dental Systems Inc. (Sirona or the Company) is the leading manufacturer of high-quality, technologically
advanced dental equipment, and is focused on developing, manufacturing and marketing innovative systems and solutions for dentists around the world. The Company is uniquely positioned to benefit from several trends in the global dental industry,
such as technological innovation, increased use of CAD/CAM systems in restorative dentistry, the shift to digital imaging, favorable demographic trends and growing patient focus on dental health and cosmetic appearance. The Company has its
headquarters in Long Island City, New York and its largest facility in Bensheim, Germany.

Sirona has a long tradition of
innovation in the dental industry. The Company introduced the first dental electric drill 130 years ago, the first dental X-ray unit 100 years ago, the first dental computer-aided design/computer-aided manufacturing (CAD/CAM) system 24
years ago, and numerous other significant innovations in dentistry. Sirona continues to make significant investments in research and development, and its track record of innovative and profitable new products continues today with numerous recent
product launches including: the inEOS Blue (launched in January 2010), the Galileos and CEREC combination (launched in September 2009), the CEREC AC unit (launched in January 2009), the Galileos Compact 3D imaging system (launched in July 2008), the
TENEO treatment center (launched in July 2008) and the CAD/CAM milling unit MC XL (launched in fiscal year 2007).

Sirona
manages its business on both a product and geographic basis and has four segments: Dental CAD/CAM Systems, Imaging Systems, Treatment Centers, and Instruments. Sirona has the broadest product portfolio in the industry, and is capable of fully
outfitting and integrating a dental practice. Products from each category are marketed in all geographical sales regions.

The
Companys business has grown substantially over the past five years, driven by numerous high-tech product introductions, a continued expansion of its global sales and service infrastructure, strong relationships with key distribution partners,
namely Patterson and Henry Schein, and an international dealer network. Patterson and Henry Schein accounted for 31% and 17%, respectively, of Sironas global revenues for the six month period ended March 31, 2010.

The U.S. market is the largest individual market for Sirona, followed by Germany. Between fiscal 2004 and 2009, the Company increased
U.S. revenues from $88.2 million to $221.2 million, driven by innovative products, particularly in the CAD/CAM and imaging segments, and the Schick acquisition. Patterson made a payment of $100 million to Sirona in July 2005 in exchange for the
exclusive distribution rights for CAD/CAM products in the U.S. and Canada until 2017 (the Patterson exclusivity payment). The amount received was recorded as deferred income and is being

recognized on a straight-line basis that commenced at the beginning of the extension of the exclusivity period in fiscal 2008.

In addition to strong U.S. market growth, Sirona has pursued expansion in non-U.S. and non-German markets. Between fiscal 2004 and 2009,
the Company increased revenues in non-U.S. and non-German markets from $190.9 million to $344.8 million. To support this growth, Sirona expanded its local presence and distribution channels by establishing sales and service locations in Japan,
Australia, China, Italy, France, and the UK. The expansion helped to increase market share but also contributed to higher SG&A expenses. Due to the international nature of the Companys business, movements in global foreign exchange rates
have a significant effect on financial results.

The weak global economy in 2009 resulted in a challenging environment for
selling dental technology, which impacted Sironas revenues. In fiscal year 2009, U.S. revenues were flat and international revenues decreased 8.2% (up 1.8% on a constant currency basis). During the year, the Company introduced breakthrough
advancements in dental care, led by the CEREC AC. In the context of the weak global economy, the Company implemented a near-term cost savings and deferral plan for 2009 and separately undertook certain targeted actions to reduce operating costs and
to increase efficiency on a longer term basis. We finished the year with a robust fourth quarter with constant currency revenue growth of 8.4%, driven by our innovative high-tech product line.

The positive trends from the fourth quarter of fiscal year 2009 continued into the first half of fiscal 2010. This development was driven
by our recent innovative product launches and our technologically advanced product portfolio. Our net income benefited from robust sales growth, margin expansion, expense management initiatives, and deleveraging. Our targeted cost saving actions are
on plan, and we expect to begin reinvesting a part of these cost savings as we move through the second half of the year. Cash flow from operations was strong, mainly driven by operating income.

Significant Factors that Affect Sironas Results of Operations

The MDP Transaction and the Exchange

The assets and liabilities acquired in the MDP Transaction and the Exchange were partially stepped up to fair value, and a related
deferred tax liability was recorded. The excess of the total purchase price over the fair value of the net assets acquired, including IPR&D, which were expensed at the date of closing of the MDP Transaction and the Exchange, was allocated to
goodwill and is subject to periodic impairment testing.

Sironas cost of goods sold, research and development, selling,
general and administrative expense and operating results have been and will continue to be materially affected by depreciation and amortization costs resulting from the step-up to fair value of Sironas assets and liabilities.

Fluctuations in U.S. Dollar/Euro Exchange Rate

Although the U.S. Dollar is Sironas reporting currency, its functional currency varies depending on the country of operation.
For the six months ended March 31, 2010, approximately 45% of Sironas revenue and approximately 71% of its expenses were denominated in Euros. During the periods under review, the U.S. Dollar/Euro exchange rate has fluctuated
significantly, thereby impacting Sironas financial results. Between October 1, 2008 and March 31, 2010, the U.S. Dollar/Euro exchange rates used to calculate items included in Sironas financial statements varied from a low of
1.2439 to a high of 1.5121 and as of March 31, 2010 and September 30, 2009 were 1.3472 and 1.4662, respectively. Although Sirona does not apply hedge accounting, Sirona has entered into foreign exchange forward contracts to manage foreign
currency exposure. As of March 31, 2010, these contracts had notional amounts totaling $72.7 million. As these agreements are relatively short-term (generally six months), continued fluctuation in the U.S. Dollar/Euro exchange rate could
materially affect Sironas results of operations.

Certain revenue information under Results of Operations
below is presented on a constant currency basis. This information is a non-GAAP financial measure. Sirona supplementally presents revenue on a constant currency basis because it believes this information facilitates a comparison of Sironas
operating results from period to period without regard to changes resulting solely from fluctuations in currency rates. Sirona calculates constant currency revenue growth by comparing current period revenues to prior period revenues with both
periods converted at the U.S. Dollar/Euro average foreign exchange rate for each month of the current period. The average monthly exchange rate for the six months ended March 31, 2010 was $1.43 and varied from $1.48102 to $1.35825. For the
three and six months

##### Table of Contents

ended March 31, 2009, an average quarterly foreign exchange rate converting Euro-denominated revenues into U.S. Dollars of $1.30799 and $1.31347, respectively, was applied.

Loans made to Sirona under the Senior Facilities Agreement entered into November 22, 2006 are denominated in the functional currency
of the respective borrowers. See Liquidity and Capital Resources for a discussion of our Senior Facilities Agreement. However, intra-group loans are denominated in the functional currency of only one of the parties to the loan
agreements. Where intra-group loans are of a long-term investment nature, the potential non-cash fluctuations in exchange rates are reflected within other comprehensive income. These fluctuations may be significant in any period due to changes in
the exchange rates between the Euro and the U.S. Dollar.

Fluctuations in Quarterly Operating Results

Sironas quarterly operating results have varied in the past and are likely to vary in the future. These variations result from a
number of factors, many of which are substantially outside its control, including:



| |  |  | the timing of new product introductions by us and our competitors;
| | - |  | ------------------------------------------------------------------



| |  |  | the timing of industry tradeshows;
| | - |  | ----------------------------------



| |  |  | changes in relationships with distributors;
| | - |  | -------------------------------------------



| |  |  | developments in government reimbursement policies;
| | - |  | --------------------------------------------------



| |  |  | changes in product mix;
| | - |  | -----------------------



| |  |  | our ability to supply products to meet customer demand;
| | - |  | -------------------------------------------------------



| |  |  | fluctuations in manufacturing costs;
| | - |  | ------------------------------------



| |  |  | income tax incentives;
| | - |  | ----------------------



| |  |  | currency fluctuations; and
| | - |  | --------------------------



| |  |  | general economic conditions, as well as those specific to the healthcare industry and related industries.
| | - |  | ---------------------------------------------------------------------------------------------------------

Due to the variations which Sirona has experienced in its quarterly operating results, it does not believe that period-to-period
comparisons of results of operations of Sirona are necessarily meaningful or reliable as indicators of current and future performance.

Effective Tax Rate

Sironas effective tax rate may vary significantly from period to period. Various factors may have a favorable or unfavorable impact
on our effective tax rate. These factors may include, but are not limited to, the actual distribution of profits across the different jurisdictions, tax planning initiatives, changes in local tax rates, as well as the timing and deductibility of
expenses for tax purposes.

Liquidity and Capital Resources

Historically, Sironas principal uses of cash, apart from operating requirements, including research and development expenses, have
been for interest payments, debt repayment and acquisitions. Operating capital expenditures are approximately equal to operating depreciation (excluding any effects from the increased amortization and depreciation expense resulting from the step-up
to fair values of Sironas and Schicks assets and liabilities required under purchase accounting). Sironas management believes that Sironas working capital is sufficient for its present requirements.

The Senior Facilities Agreement contains restrictive covenants that limit Sironas ability to make loans, make investments
(including in joint ventures), incur additional indebtedness, make acquisitions or pay dividends, subject to agreed exceptions. The Company has agreed to certain financial debt covenants in relation to the financing. The covenants stipulate that the
Company must maintain certain ratios in respect of interest payments and defined earnings measures. If the Company breaches any of the covenants, the loans will be become repayable on demand.

The financial covenants require that the Company maintain a debt coverage ratio (Debt Cover Ratio) of consolidated total net
debt to consolidated adjusted EBITDA (Consolidated Adjusted EBITDA) of no more than 2.50 to 1, and a cash interest coverage ratio (Cash Interest Cover Ratio) of consolidated adjusted EBITDA to cash interest costs of 4.00 to 1
or greater. The Company is required to test its ratios as of September 30 and March 31. As calculated in accordance with the Senior Facilities Agreement, the following table presents the Companys actual Debt Cover Ratio and Cash
Interest Cover Ratio, and their respective components, for required testing periods in fiscal year 2010 and 2009:

Net Cash Provided by Operating Activities

Net cash provided by operating activities represents net cash from operations, returns on investments, and payments for interest and
taxation.

Net cash provided by operating activities was $74.8 million for the six months ended March 31, 2010, compared
to $21.9 million for the six months ended March 31, 2009. The primary contributing factor to the increase in cash provided by operating activities was an increase in operating income, as well as an improvement in working capital.

Net Cash Used in Investing Activities

For the six months ended March 31, 2010, net cash used in investing activities represents cash used in capital expenditures in the
course of normal operating activities, partly offset by proceeds from the sale of a subsidiary in Italy. The investing cash outflow for the six months ended March 31, 2009, resulted from capital expenditures in the course of normal operating
activities, partly offset by proceeds from the sale of a subsidiary in Spain.

Net Cash Used in Financing Activities

Net cash used in financing activities was $73.9 million for the six months ended March 31, 2010, compared to net cash used in
financing activities of $1.3 million for the six months ended March 31, 2009. Net cash used in financing activities in the six months ended March 31, 2010 primarily relates to the early repayment of senior debt that was originally due in
November 2010 eight months ahead of schedule, partly offset by proceeds and tax-related benefits of stock options exercised in the first half of the fiscal year. Net cash used in financing activities in the six months ended March 31, 2009,
related to the repayment of a bank loan in China and the purchase of treasury shares under the stock repurchase program.

Sironas management believes that Sironas operating cash flows and available cash (including restricted cash), together with
its long-term borrowings, will be sufficient to fund its working capital needs, research and development expenses, anticipated capital expenditure and debt service requirements for the foreseeable future.

Capital Resources

Senior
Facilities Agreement

On November 22, 2006, Sirona Dental Systems, Inc. entered into a senior facilities
agreement (the Senior Facilities Agreement) as original guarantor, with Schick Technologies, Inc., a New York company and wholly owned subsidiary of Sirona (Schick NY), as original borrower and original guarantor, with
Sirona Dental Systems GmbH, as original borrower and original guarantor, with Sirona Dental Services GmbH, as original borrower and original guarantor and with Sirona Dental Systems LLC, Sirona Holding GmbH (subsequently merged with Sirona Dental
Services GmbH) and Sirona Immobilien GmbH as original guarantors. Initial borrowings under the Senior Facilities Agreement plus excess cash were used to retire the outstanding borrowings under the Companys previous credit facilities.

The Senior Facilities Agreement includes: (1) a term loan A1 in an aggregate principal amount of $150 million (the
tranche A1 term loan) available to Sironas subsidiary, Schick NY, as borrower; (2) a term loan A2 in an aggregate principal amount of Euro 275 million (the tranche A2 term loan) available to Sironas
subsidiary, Sirona Dental Services GmbH, as borrower; and (3) a $150 million revolving credit facility available to Sirona Dental Systems GmbH, Schick NY and Sirona Dental Services GmbH, as initial borrowers. The revolving credit facility
is available for borrowing in Euro, U.S. Dollars, Yen or any other freely available currency agreed to by the facility agent. The facilities are made available on an unsecured basis. Subject to certain limitations, each European guarantor
guarantees the performance of each European borrower, except itself, and each U.S. guarantor guarantees the performance of each U.S. borrower, except itself. There are no cross-border guarantees since all guarantees are by entities that have the
same functional currency as the currency in which the respective guaranteed borrowing is denominated.

Each of the senior term
loans has a five year maturity and is to be repaid in three annual installments beginning on November 24, 2009 and ending on November 24, 2011. Of the amounts borrowed under the term loan facilities, 15% was due on November 24, 2009,
15% was due on November 24, 2010 and 70% is due on November 24, 2011. The senior debt repayment tranche originally scheduled for November 24, 2009 was prepaid on May 11, 2009 in the amount of $78.6 million, and the senior debt
repayment tranche originally scheduled for November 24, 2010 was prepaid on March 31, 2010 in the amount of $78.1 million. At the Companys current Debt Cover Ratio, the facilities bear interest of Euribor, for Euro-denominated loans,
and Libor for the other loans, plus a margin of 45 basis points for both.

The Senior Facilities Agreement contains a margin
ratchet. Pursuant to this provision, which applies from November 24, 2007 onwards, the applicable margin will vary between 90 basis points and 45 basis points per annum according to the Companys leverage multiple (i.e. the ratio of
consolidated total net debt to consolidated adjusted EBITDA as defined in the Senior Facilities Agreement). Interest rate swaps were established for 66.6% of the interest until March 2010. These swaps expired on March 31, 2010 and were not
renewed. The interest rate swaps fixed the LIBOR or EURIBOR element of interest payable on 66.7% of the principal amount of the loans for defined twelve and



31

##### Table of Contents

thirteen month interest periods over the lifetime of the swaps, respectively. The defined interest rates fixed for each twelve or thirteen month interest period ranged from 3.50% to 5.24%.
Settlement of the swaps was required on a quarterly basis.

The Senior Facilities Agreement contains restrictive covenants
that limit Sironas ability to make loans, make investments (including in joint ventures), incur additional indebtedness, make acquisitions or pay dividends, subject to agreed exceptions. The Company has agreed to certain financial debt
covenants in relation to the financing. The covenants stipulate that the Company must maintain certain ratios in respect of interest payments and defined earnings measures. If the Company breaches any of the covenants, the loans will be become
repayable on demand.

Debt issuance costs of $5.6 million were incurred in relation to the new financing and were capitalized
as deferred charges.

EBITDA is a non-GAAP financial measure that is
reconciled to net income, its most directly comparable U.S. GAAP measure, in the accompanying financial tables. EBITDA is defined as net earnings before interest, taxes, depreciation, and amortization. Sironas management utilizes EBITDA as an
operating performance measure in conjunction with U.S. GAAP measures, such as net income and gross margin calculated in conformity with U.S. GAAP. EBITDA should not be considered in isolation or as a substitute for net income prepared in accordance
with U.S. GAAP. There are material limitations associated with making the adjustments to Sironas earnings to calculate EBITDA and using this non-GAAP financial measure. For instance, EBITDA does not include:



| |  |  | interest expense, and because Sirona has borrowed money in order to finance its operations, interest expense is a necessary element of its costs and
ability to generate revenue;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | depreciation and amortization expense, and because Sirona uses capital and intangible assets, depreciation and amortization expense is a necessary
element of its costs and ability to generate revenue; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | tax expense, and because the payment of taxes is part of Sironas operations, tax expense is a necessary element of costs and impacts
Sironas ability to operate.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, other companies may define EBITDA differently. EBITDA, as
well as the other information in this filing, should be read in conjunction with Sironas consolidated financial statements and footnotes.

In addition to EBITDA, the accompanying financial tables also set forth certain supplementary information that Sirona believes is useful
for investors in evaluating Sironas underlying operations. This supplemental information includes gains/losses recorded in the periods presented which relate to the early extinguishment of debt, share based compensation, revaluation of
U.S. Dollar denominated exclusivity payment and borrowings where the functional currency is Euro, and the Exchange. Sironas management believes that these items are either nonrecurring or noncash in nature, and should be considered by
investors in assessing Sironas financial condition, operating performance and underlying strength.

##### Table of Contents

Sironas management uses EBITDA together with this supplemental information as an
integral part of its reporting and planning processes and as one of the primary measures to, among other things:



| | (i) | monitor and evaluate the performance of Sironas business operations;
| | --- | ---------------------------------------------------------------------



| | (ii) | facilitate managements internal comparisons of the historical operating performance of Sironas business operations;
| | ---- | ---------------------------------------------------------------------------------------------------------------------



| | (iii) | facilitate managements external comparisons of the results of its overall business to the historical operating performance of other companies that may have
different capital structures and debt levels;
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | analyze and evaluate financial and strategic planning decisions regarding future operating investments; and
| | ---- | -----------------------------------------------------------------------------------------------------------



| | (v) | plan for and prepare future annual operating budgets and determine appropriate levels of operating investments.
| | --- | ---------------------------------------------------------------------------------------------------------------

Sironas management believes that EBITDA and the supplemental information provided is useful to investors as it provides them with
disclosures of Sironas operating results on the same basis as that used by Sironas management.
