Overview

Sirona Dental Systems, Inc. (Sirona, the Company, we, us, and our refer to Sirona
Dental Systems, Inc. and its consolidated subsidiaries and their predecessors) is the leading manufacturer of high-quality, technologically-advanced dental equipment, and is focused on developing, manufacturing and marketing innovative 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. Sirona provides a broad range of technologically advanced products in each of its four product segments:



| |  |  | Dental CAD/CAM Systems;
| | - |  | -----------------------



| |  |  | Imaging Systems;
| | - |  | ----------------



| |  |  | Treatment Centers; and
| | - |  | ----------------------



| |  |  | Instruments.
| | - |  | ------------

Sirona markets its products globally to dental practices, clinics and laboratories through an international network of distributors. These dental distributors typically supply both dental equipment and
consumables, and have regular contact with the ultimate end-users.

Sironas revenue for the fiscal year ended
September 30, 2010 was $770.3 million. Sirona sells its products globally, with the U.S. market contributing 31% of revenue, or $239.5 million, the German market contributing 19% of revenue, or $148.3 million, and the rest of the world
contributing 50% of revenue, or $382.4 million.

History

Sirona dates back to the establishment of Reiniger, Gebbert & Schall, which introduced the first dental electrical drill in 1882. In 1925, the Company became part of Siemens & Halske
Group and in 1934 launched the smallest x-ray in the world, enabling dental x-rays for the first time. In 1956, Siemens introduced Sirona as a brand for treatment centers, and in 1958 the group developed the first ball-bearing turbine for dental
drills.

In 1997, funds advised by the financial sponsor, Permira, acquired the Sirona dental business from Siemens in a
leveraged buy-out transaction. Following the transaction, Sirona substantially increased its international sales and intensified its focus on product innovation. In November 2003, Permira sold Sirona to the Scandinavian financial sponsor, EQT, and
management in a leveraged buy-out transaction that closed on February 16, 2004. On April 30, 2005, funds managed by Madison Dearborn Partners, a private equity firm, and Sironas management entered into an agreement to acquire Sirona
in a leveraged buy-out transaction that closed on June 30, 2005.

On September 25, 2005, Schick Technologies, Inc.
(Schick) entered into an Exchange Agreement with Sirona Holdings Luxco S.C.A. (Luxco) and Sirona Holding GmbH (Sirona Holding) providing for the issuance of 36,972,480 shares of Schick common stock to Luxco in
exchange for Luxcos entire economic interest in Sirona Holding, which consisted of all of the issued and outstanding share capital of Sirona Holding and the existing indebtedness of Sirona Holding owed to Luxco in the principal amount of Euro
151.0 million ($182 million) plus accrued interest (the Exchange). On June 20, 2006, the Exchange closed and Schick, a Delaware corporation formed in 1997, was renamed Sirona Dental Systems, Inc. Although Sirona Holding became
a subsidiary of Schick upon the completion of the Exchange, Sirona Holding was deemed the acquiring corporation for accounting purposes because Luxco received a controlling ownership interest in the Company, Sirona Holdings designees
constituted a majority of the members of the Companys board of directors and Sirona Holdings senior management represented a majority of the senior management of the Company.

Schicks business was founded in 1992 and completed an initial public offering of its common stock on July 1, 1997. Our common
stock is currently traded publicly on the NASDAQ Global Select Market. In connection with the Exchange, we changed our trading symbol to SIRO from SCHK. Previously, from September 16, 1999 through December 20, 2005,
Schicks common stock was traded on the Over-the-Counter (OTC) Bulletin Board under the trading symbol SCHK.

Industry/Products

Overview

The global dental market encompasses the diagnosis, treatment and
prevention of disease and ailments of the teeth, gums and supporting bone. This market has enjoyed steady growth, driven by a number of factors, including an increased desire for aesthetics, a demographic shift towards an aging population coupled
with a desire to retain tooth structure later in life, growth in disposable income, a desire for more convenience on the part of both dentists and patients, a shift towards private pay, a greater need for dental preventative care and technological
innovation.

The global dental market has benefited from technological developments, which increase productivity for the
dentist. This is particularly important in markets facing increased demand for dental services with little or no increase in the number of dentists servicing those markets. In addition, technological developments allow dentists to offer higher
quality treatment to patients. We believe that the high-tech end of the dental market is growing at a faster pace than the overall dental market and that this trend will continue over time.

Recent technological advancements in the dental equipment industry include 3D radiography, digital radiography, CAD/CAM technology, and
intra oral cameras.

The market we serve comprises the whole working environment of a dentist or dental technician, including
the dentists chair, lights, imaging systems and dental CAD/CAM systems, instruments, as well as practice furniture and other dental or lab-based systems. These are important investments by the practitioner, and the products can have an average
life cycle of 10-20 years (shorter for instruments and software), depending on the nature and quality of the product.

Products

Our principal products can be generally classified into the following segments: Dental CAD/CAM Systems, Imaging Systems,
Treatment Centers and Instruments.

A brief description of each of our segments follows. See Note 23 to our consolidated
financial statements for revenues and gross profit by segment for each of the last three fiscal years, and assets by segment, at September 30, 2010 and 2009.

Dental CAD / CAM Systems

Dental CAD/CAM Systems address the
worldwide market for dental restorations, which includes several types of restorations, such as inlays, onlays, veneers, crowns, bridges, copings and bridge frameworks made from ceramic, metal or composite blocks. The global market for dental
restorations can be divided into two sub-segments: in-mouth fillings and out-of-mouth pre-shaped restorations. CAD/CAM-produced ceramic restorations represent a growing portion of the out-of-mouth restoration market and the number of out-of-mouth
restorations prepared with CAD/CAM systems has increased substantially over the past few years. At the same time, the number of dental practitioners and dental laboratories using CAD/CAM technology has increased. Sirona estimates that as of the end
of fiscal year 2010, the market penetration for in-office CAD/CAM systems in the United States had grown to approximately 11% and increased to approximately 13% in Germany.

Sirona pioneered the application of high-tech CAD/CAM techniques to the traditional lab-based restoration process with the commercialization of the CEramic REConstruction, or CEREC, method. Sironas
CEREC system is an in-office application that enables dentists to produce high quality restorations from ceramic material and insert them into the patients mouth during a single appointment. CEREC has a number of advantages compared to the
traditional out-of-mouth pre-shaped restoration method, as CEREC does not require a physical model, restorations can be created in the dentists office and the procedure can be completed in a single visit. The CEREC system consists of an
imaging unit and a milling unit. The imaging unit scans the damaged area, captures the image of the tooth or teeth requiring restoration and proposes the specifications for the restoration. The milling unit then mills the ceramic restoration to the
required specifications based upon the captured image and the dentists design specifications. The result is a biocompatible, non-metallic, natural-looking restoration made of durable, high-quality ceramic materials completed in a single
treatment session. Independent studies indicate that CEREC ceramic restorations are as durable as gold and can replace conventional restoration materials for most procedures. In addition, CEREC restorations are aesthetically pleasing and have the
benefit of a natural-looking appearance.

In fiscal year 2003, Sirona launched its CEREC 3D product, an important development
that allowed the dentist to view the onscreen restoration in three dimensions. This product has been periodically updated, including enhanced software applications. In fiscal year 2007, Sirona launched its next generation milling unit, the MC XL.
The MC XL produces a high quality, precisely fitted restoration in half the time that the classic CEREC milling unit requires. Fiscal year 2007 also saw the

roll out of Sironas Biogeneric software which virtually automates the CAD portion of the CAD/CAM process. This software has been further enhanced to include crowns and bridges
and version 3.8 has been launched in fiscal year 2010. In January 2009, Sirona launched the CEREC AC Digital Impression Unit, which is based on the Bluecam technology, further strengthening its leadership position in the dental CAD/CAM market. The
AC unit takes digital dental impressions quickly, more accurately and with improved workflow. This advanced digital impression acquisition unit significantly expands the range of clinical indications and gives CEREC dentists the choice of either
creating the restoration in-office or sending a digital impression to a laboratory, which then fabricates the restoration from the digital model.

Sirona offers a service contract on its CEREC product, which includes software updates and upgrades and maintenance on software-related hardware.

In addition to CEREC, Sirona also offers CAD/CAM products for dental laboratories, including the inLab restoration fabrication system and
the extra-oral inEos scanner. These products are designed to improve efficiency and reduce costs for the dental lab. The inLab system scans the models received from the dentists and then mills ceramic or composite block restorations, such as crown
copings and bridge frameworks to the specifications of the captured image. In fiscal year 2007, Sirona launched its next generation inLab milling unit, the inLab MC XL. The new unit features a modern, elegant design with solid, heavy-duty
construction. Milling performance and precision have been greatly enhanced and milling time has been considerably reduced. The inEos scanner, which was launched in 2005, is a high speed extra-oral scanner which produces 3D digital images from a
single tooth up to a jaw, directly from the plaster model. In fiscal year 2010, the successor model inEos Blue was launched. inEos Blue is based on the Bluecam technology, is easy to use, fast, precise, flexible, and its auto capture function
allows for substantial time savings.

In fiscal year 2004, Sirona started its central restoration service business for copings
and bridge-frameworks in Germany and expanded the service to the United States in fiscal year 2006. The central restoration service allows dental labs to scan a plaster model received from the dentist and then transmit the digital image directly to
Sirona via the internet. A bridge or coping is then created at Sironas central manufacturing site; with the final product shipped directly back to the lab.

In fiscal year 2008, we expanded our CEREC offering with the introduction of CEREC Connect. CEREC Connect is a web-based service that facilitates the electronic transmission of digital impressions
acquired with a CEREC acquisition unit to inLab laboratories. Laboratories can use the digital impression to create final restorations. This process eliminates the need to take physical impressions, resulting in increased accuracy, less reworking of
restorations and productivity savings.

The Dental CAD/CAM Systems segment contributed 34%, 35% and 31% to Sironas
revenue for the fiscal years ended September 30, 2010, 2009 and 2008, respectively.

Imaging Systems

Imaging Systems comprise a broad range of digital and film-based systems for diagnostic imaging in the dental practice. Sirona has
developed a comprehensive range of imaging systems for 2D and 3D, panoramic and intra-oral applications that allow the dentist to accommodate the patient in a more efficient manner.

Intra-oral x-ray systems use image-capture devices (film or sensor), which are inserted into the mouth behind the diagnostic area, and
typically take images of one or two teeth. Panoramic x-ray systems produce images of the entire jaw structure by means of an x-ray tube and an image capture device, which rotates around the head.

In 2004, Sirona introduced its next generation of digital panoramic x-ray systems, the Orthophos XG line. The flagship model, the
Orthophos XG Plus, provides specialists, orthodontists, oral surgeons and implantologists with over 30 programs and a wide variety of diagnostic possibilities. Other models of the family include the Orthophos XG 5 and the basic model Orthophos XG 3,
both of which are designed for general dental practitioners.

As a result of the Exchange, we expanded our imaging system
product line to include Schicks CDR (computed digital radiography) system, the leading intra-oral digital imaging system in the United States. Schicks product line includes an imaging sensor based on CMOS technology and the Schick Pan, a
digital panoramic unit.

In fiscal year 2007, Sirona introduced its GALILEOS Comfort 3-D imaging unit. Today,
three-dimensional imaging is offering dentists advanced diagnostic and therapeutic options in the fields of surgery, prosthetics, orthodontics, and restorative dentistry. The Company believes GALILEOS integrates these capabilities efficiently into
dental practices. In July 2008, Sirona launched GALILEOS Compact, which is specifically tailored to meet the needs of the general practitioner. GALILEOS Comfort and GALILEOS Compact also have the ability to display traditional 2-D panoramic digital
images. In fiscal year 2009, Sirona introduced software that facilitates the integration of Galileos 3D X-ray volume (bone level data) with

a CEREC AC CAD/CAM scan (surface level information). This software allows the practitioner to plan both the implant surgery and the prosthetic at the start of the implant treatment session. This
integrated process reduces the number of treatment sessions, results in greater accuracy and superior implant alignment. With this new software, the dental practitioner can now place more focus on the desired aesthetic outcome throughout the entire
treatment process.

The Imaging Systems segment contributed 33%, 32% and 34% to Sironas revenue for the fiscal years
ended September 30, 2010, 2009 and 2008, respectively.

Treatment Centers

Treatment Centers comprise a broad range of products from basic dentist chairs to sophisticated chair-based units with integrated
diagnostic, hygiene and ergonomic functionalities, as well as specialist centers used in preventative treatment and for training purposes. Sirona offers specifically configured products to meet the preferences of dentists within each region in which
it operates. Sironas treatment center configurations and system integration are designed to enhance productivity by creating a seamless workflow within the dental practice. Sironas centers therefore allow the dentist to both improve
productivity and increase patient satisfaction, significant factors in adding value to his or her practice. In October 2004, Sirona acquired one of the leading Chinese manufacturers of basic treatment centers, located in Foshan (South China). This
facility manufactures basic products for both the domestic Chinese market and export markets.

In July 2008, Sirona launched
its new TENEO Treatment Center, which combines industry-leading technology with a timeless design that provides both patient and dentist with the ultimate in convenience and comfort.

The Treatment Centers segment contributed 21%, 21% and 22% to Sironas revenue for the fiscal years ended September 30, 2010,
2009 and 2008, respectively.

Instruments

Sirona offers a wide range of instruments, including handheld and power-operated handpieces for cavity preparation, endodontics, periodontology and prophylaxis. The instruments are supplemented by
multi-function tips, supply and suction hoses, as well as care and hygiene systems for instrument preparation. Sironas instruments are often sold as packages in combination with treatment centers. During the last several years, Sirona
introduced a variety of new products, including SIROLaser, a compact diode laser; PerioScan, an all-in-one ultrasonic scaling unit enabling both diagnosis and treatment of dental calculus with a single device; SIROEndo, a root canal preparation
unit; and SIROPure, oil-free, power-driven handpieces.

Sirona intends to continue to strengthen the position of its
Instruments segment as a diversified supplier of high-quality, reliable, user-friendly and cost-efficient dental instruments.

The Instruments segment contributed 12%, 12% and 13% to Sironas revenue for the fiscal years ended September 30, 2010, 2009
and 2008, respectively.

Manufacturing and Suppliers

Our main manufacturing and assembly activities are located in Bensheim, approximately 60 kilometers south of Frankfurt am Main, Germany. We also operate smaller manufacturing sites in New York, Italy,
Denmark and China. All of our facilities are in good condition.

All of our manufacturing facilities have established and
maintain a Quality Management System that is registered to ISO 9001:2000 and ISO 13485:2003. Our New York and Bensheim facilities also maintain a Device Establishment Registration with the United States Food and Drug Administration.

Manufacturing consists primarily of assembly, systems integration and testing. We generally outsource manufacturing of parts and
components used in the assembly of our products but own the design and tools used by our key component suppliers. We do, however, manufacture most of the precision parts used for our instruments, and we also operate an Electronic Center for the
supply of electronic boards and components.

##### Table of Contents

We purchase various components for our products from a number of outside suppliers. We
currently have established relationships with approximately 1,300 suppliers, of which we view approximately 250 as key suppliers. Each supplier is selected according to stringent quality criteria, which are reviewed regularly. We do not
believe we are dependent on one or a small group of suppliers and believe we could locate alternative suppliers if needed. For reasons of quality assurance or cost effectiveness, the Company relies on single sources for certain purchased components,
e.g. sensors, which we use in our imaging segment. We work closely with our suppliers to help ensure continuity of supply while maintaining high quality and reliability. We have agreements in place and use a number of techniques, including security
or consignment stock commitments, to address potential disruptions of the supply chain. We also own any custom tooling used in manufacturing these components. The Company has not experienced any significant difficulty in the past in obtaining the
materials necessary to meet its production schedule. However, the need to replace one of our single source suppliers could cause a disruption in our ability to timely deliver certain of our products or increase costs. See Item 1A Risk Factors
 We are dependent upon a limited number of suppliers for critical components. If these suppliers delay or discontinue the manufacture of these components, we may experience delays in shipments, increased costs and cancellation of orders
for our products.

Sales and Marketing

Our sales and marketing efforts are directed through regional managers who oversee our sales professionals. These professionals work closely with our distribution partners to maximize the efficiency and
productivity of their sales efforts. Our marketing initiatives are focused on highlighting Sironas leading role as a high-tech systems provider and industry innovator. In order to promote our brand and increase client loyalty, our distribution
partners are supported through wide ranging advertising activities. In addition, we have been a key presenter at all major dental exhibitions, which are critical forums for raising brand awareness and new product introductions. Lastly, our product
information is actively made available to business publications, dentists, journals, professional organizations and dental schools, and our website (www.sirona.com) is an important interactive platform for end-users as well as for distributors.

Distribution

Sirona distributes its products globally to dental practices, clinics and laboratories through an international network of more than 300
distributors. See Note 23 to our consolidated financial statements for a description of our net sales and long-lived assets by geographic region for the last three fiscal years. Because distributors typically cover both dental equipment and
consumables, they have regular contact with the dentist and are therefore optimally positioned to identify new equipment sale opportunities. Sironas primary distributors are Patterson Companies and Henry Schein, two of the worlds largest
dental distributors. In the United States, Patterson is Sironas primary distributor. Outside of the United States, Henry Schein is the companys largest distributor. Patterson Companies and Henry Schein accounted for 30% and 15%,
respectively, of Sironas worldwide revenue for the fiscal year ended September 30, 2010. Sirona distributes elsewhere through a well developed network of independent regional distributors. Sirona works closely with its distributors by
training their technicians and sales representatives with respect to its products. With over 9,000 sales and service professionals trained each year, Sirona seeks to ensure high standards of quality in after-sale service and the best marketing of
its products. The success of Sironas products is evidenced by their importance to its distribution partners, and in many cases are among their best selling offerings.

On April 27, 1998, Sirona and Patterson Companies entered into an exclusive distribution agreement (the Distribution Agreement) pursuant to which Patterson was appointed as the exclusive
distributor of Sironas CEREC CAD/CAM products within the United States and Canada. Under the terms of the Distribution Agreement, Pattersons exclusivity was to terminate on September 30, 2007. On June 30, 2005, Sirona and
Patterson entered into an amendment of the Distribution Agreement which extended Pattersons exclusivity from October 1, 2007 through September 30, 2017. As consideration for the extension of its exclusivity, Patterson agreed to make
a one-time payment to Sirona in the amount of $100 million (the Exclusivity Fee). In July 2005, Patterson paid the Exclusivity Fee, in its entirety, to Sirona. The full amount of the Exclusivity Fee was recorded as deferred income and is
being recognized on a straight-line basis commencing on October 1, 2007. In the event of termination of the Distribution Agreement (a) due to force majeure, (b) by Patterson due to Sironas insolvency, or (c) by Sirona as a
result of a failure by Patterson to meet its performance obligations, Sirona would be required to refund to Patterson a portion of the Exclusivity Fee as liquidated damages. The amount of the Exclusivity Fee required to be refunded declines by $15
million per year in each of fiscal years 2008 through 2012 and by $5 million per year thereafter. In the event of termination by Patterson due to a breach by Sirona of its exclusivity obligations, the unearned portion of the Exclusivity Fee (as
determined on a straight-line basis beginning in fiscal year 2008) must be refunded to Patterson as liquidated damages. The extension did not modify or alter the underlying provisions of the companies agreement through 2007, including the
performance criteria necessary to maintain the exclusivity. The performance criteria are benchmark thresholds which afford Sirona the opportunity to abandon the exclusivity or to terminate the agreement with Patterson, but do not create minimum
purchase obligations under a take-or-pay arrangement.

In April 2000, Schick and Patterson entered into an exclusive
distribution agreement covering the United States and Canada; and as of May 1, 2000, Schick began marketing and selling its CDR dental products in the United States and Canada through Patterson. This contract was amended in July
2005, March 2007, and May 2010 and is due to expire on December 31, 2012.

##### Table of Contents

Sirona executes separate contracts with Henry Schein for each product group in each of the
various jurisdictions in which Henry Schein distributes its products. The contracts governing most of the products distributed through Henry Schein are non-exclusive. Each of the contracts provides for minimum annual purchases, which are set
annually. The contracts have terms of up to five years. Either party is entitled to terminate any of the contracts upon six months notice but generally not before the third anniversary of the contract. Sirona may terminate a contract upon 30
days notice in case of Henry Scheins default under the terms of the contract.

Competition

Competition in the global dental market is fragmented by both geography and products. We compete with a variety of companies, including
large international companies as well as smaller companies that compete regionally or on a narrower product line. Sirona competes on the basis of its comprehensive and innovative product line and its global distribution network.

Research and Development

Sirona commits significant resources to research and development, with a particular focus on developing products that offer new diagnostic
and treatment options, while increasing comfort for both users and patients and streamlining process efficiency. Sirona spent approximately $46 million, $41 million and $49 million on research and development activities in the fiscal years ended
September 30, 2010, 2009 and 2008, respectively, which represented approximately 6% of Sironas total revenue in each year. Sirona employs 223 professionals in its global research and development departments. Sirona also cooperates in its
research efforts with partners in research facilities and dental practices around the world.

Patents, Trade Secrets and Proprietary Rights

We seek to protect our intellectual property through a combination of patent, trademark and trade secret protection. We
believe that our future success will depend in part on our ability to obtain and enforce patents for our products and processes, preserve our trade secrets and operate without infringing the proprietary rights of others.

Patents

We have
an active corporate patent program, the goal of which is to secure patent protection for our technology. Sirona owns and/or maintains approximately 700 patents and patent applications throughout the world. The patents expire at various dates through
2027. We also license or sublicense some of the technology used in our products from third parties.

Trademarks

We generally attempt to build brand awareness of our products through the use of trademark registrations. Sirona,
CEREC, Orthophos, Heliodent, inLab, CDR, and Schick are some of our key registered trademarks. In addition, we have common law trademark rights in several other names we use
commercially in connection with our products.

Trade Secrets

In addition to patent protection, we own trade secrets and proprietary know-how, which we seek to protect, in part, through appropriate
agreements with employees, and, to a limited degree, employment agreements with appropriate individuals. These agreements generally allow assignment of confidential information developed by or made known to the individual by the Company during the
course of the individuals relationship with the Company as confidential and not to be disclosed to third parties, except in specific limited circumstances. The agreements also generally assign to the Company all inventions conceived by the
individual in the course of rendering services to the Company. However, there can be no assurance that the Company will be successful in enforcing this policy in each case, that the Company would have adequate remedies available for any breach or
that the Companys trade secrets will not otherwise become known to, or independently developed by, its competitors.

Regulation

Medical Devices

Most of our products require certain forms of
regulatory clearance, including, but not limited to, marketing clearance by the United States Food and Drug Administration (the FDA) in accordance with the Federal Food, Drug and Cosmetic Act, as amended (the FD&C Act)
and by our Notified Body in accordance with the European Unions Medical Device Directive 93/42/EEC (MDD).

The FDA and MDD review process typically requires extended proceedings pertaining to product safety and efficacy. We believe that our
future success will depend to a large degree upon commercial sales of improved versions of our current products and sales of new products; we will not be able to market such products in the U.S. or in the European Union without FDA or MDD clearance,
respectively. There can be no assurance that any products developed by us in the future will be granted clearance by applicable regulatory authorities or that additional regulations will not be adopted or current regulations amended in such a manner
as to adversely affect us.

Pursuant to the FD&C Act, the FDA regulates the introduction, manufacture, advertising,
labeling, packaging, marketing and distribution of, and record-keeping for dental devices. The FDA classifies medical devices intended for human use into three classes: Class I, Class II, and Class III. The Companys products are classified by
the FDA into Class I or II that renders them subject only to general controls that apply to all medical devices, in particular regulations regarding alteration, misbranding, notification, record-keeping and good manufacturing practices.

The FD&C Act further provides that, unless exempted by regulation, medical devices may not be commercially distributed in the U.S.
unless they have been cleared by the FDA. There are two review procedures by which medical devices can receive such clearance. Some products may qualify for clearance under a Section 510(k) procedure, in which the manufacturer submits to the
FDA a pre-market notification that it intends to begin marketing the product, and shows that the product is substantially equivalent to another legally marketed product (i.e., that it has the same intended use and that it is as safe and effective as
a legally marketed device, and does not raise different questions of safety and effectiveness than does a legally marketed device). Certain Class I devices are exempt from the 510(k) pre-market notification requirement and manufacturers of such
products may proceed to market without any submission to the FDA. In some cases, the 510(k) notification must include data from human clinical studies.

Marketing in the U.S. may commence once the FDA issues a clearance letter finding such substantial equivalence. According to FDA regulations, the agency has 90 days in which to respond to a Class I or II
510(k) notification. There can be no assurance, however, that the FDA will provide a timely response, or that it will reach a finding of substantial equivalence.

If a product does not qualify for the 510(k) procedure (either because it is not substantially equivalent to a legally marketed device or because it is a Class III device), the FDA must approve a
Pre-Market Approval (PMA) application before marketing can begin. PMA applications must demonstrate, among other things, that the medical device is safe and effective. A PMA application is typically a complex submission that includes the
results of clinical studies. Preparation of such an application is a detailed and time-consuming process. Once a PMA application has been submitted, the FDAs review process may be lengthy and include requests for additional data. By statute
and regulation, the FDA may take 180 days to review a PMA application, although such time may be extended. Furthermore, there can be no assurance that the FDA will approve a PMA application.

The products that we distribute in the European Union bear the CE Mark, a European Union symbol of compliance with the MDD.
In order to market our products in the member countries of the European Union, it is necessary that those products conform to the requirements of the MDD. Our Bensheim facility which is engaged in the manufacturing of Class IIa and Class IIb medical
devices as defined by the MDD is ISO 13485 certified. It is also necessary that our products comply with any revisions which may be made to these standards or the MDD.

Medical devices are subject to ongoing regulatory oversight by the FDA and a Notified Body. The FD&C Act requires that all medical device manufacturers and distributors register annually with the FDA
and submit a list of those medical devices which they distribute commercially. The MDD requires that Class IIa devices or higher bear a CE mark with a Notified Body Number. The FD&C Act and the MDD also requires that all manufacturers of medical
devices comply with labeling requirements and manufacture their products and maintain their documents in a prescribed manner with respect to manufacturing, testing, and quality control activities. The FDAs Medical Device Reporting regulation
and the MDD subject medical devices to post-market reporting requirements for death or serious injury, and for certain malfunctions that would be likely to cause or contribute to a death or serious injury if malfunction were to recur. In addition,
the FDA and the MDD

prohibit a device which has received marketing clearance from being marketed for applications for which marketing clearance has not been obtained. Furthermore, the FDA generally requires that
medical devices not cleared for marketing in the U.S. receive FDA marketing clearance before they are exported, unless an export certification has been granted. The FDA and the ISO Notified Bodies regularly inspect our registered and/or certified
facilities.

Failure to comply with applicable regulatory requirements can, among other consequences, result in fines,
injunctions, civil penalties, suspensions or loss of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution. In addition, governmental regulations may be established that could prevent or delay
regulatory clearance of our products. Delays in receipt of clearance, failure to receive clearance or the loss of previously received clearance would have a material adverse effect on our business, financial condition and results of operations.

Environmental, Health and Safety Matters

In addition to the laws and regulations discussed above, we are subject to government regulations applicable to all businesses, including, among others, regulations related to occupational health and
safety, workers benefits and environmental protection. The extent of government regulation that might result from any future legislation or administrative action cannot be accurately predicted. Failure to comply with regulatory requirements
could have a material adverse effect on our business, financial condition and results of operations.

Employees

As of September 30, 2010, the Company had 2,345 employees. The Company believes that its relations with its employees are good. No
Company employees are represented by labor unions or are subject to a collective bargaining agreement in the United States. Approximately 25% of our German employees are members of the IG Metall union. We have not experienced any work stoppages due
to labor disputes.

|ITEM 1A. | RISK FACTORS
|-------- | ------------

These risk
factors may be important to understanding any statement in this Annual Report on Form 10-K or elsewhere. The following information should be read in conjunction with Managements Discussion and Analysis of Financial Condition and Results of
Operations (MD&A), and the consolidated financial statements and related notes incorporated by reference in this report.

Our businesses routinely encounter and address risks, some of which will cause our future results to be different - sometimes materially
different - than we anticipate. Discussion about the material operational risks that our businesses encounter can be found in our MD&A, in the business descriptions in Item 1 of this report and in previous SEC filings. Below, we have
described our present view of the material risks facing our business.

Risks Related to Our Business

We must develop new products and enhancements to existing products to remain competitive.

We are currently developing new products and enhancements to existing products. We cannot assure you that we will initiate, continue with
and/or succeed in our efforts to develop or enhance such products. It is expected that we will file 510(k) applications with the Food and Drug Administration, or FDA, and similar filings with governmental authorities in other countries in
connection with our future products and certain of our future product enhancements. There can be no assurance that we will file applications for or obtain regulatory approval from the FDA, either in the form of a pre-market clearance or a
510(k) clearance, for any of our future products, or that in order to obtain FDA clearance, we will not be required to submit additional data or meet additional FDA requirements that may substantially delay the application process and result in
substantial additional expense. In addition, such pre-marketing clearance, if obtained, may be subject to conditions on marketing or manufacturing which could impede our ability to manufacture and/or market our products. There can be no assurance
that any new products will be developed by us, or if developed, will be approved by, or receive marketing clearance from, applicable domestic and/or international governmental or regulatory authorities. If we are unable to develop, obtain regulatory
approval for and market new products and enhancements to existing products, our business and results of operations could be harmed.

If
we cannot obtain or maintain approval from government agencies, we will not be able to sell our products.

We must
obtain certain approvals by, and marketing clearances from, governmental authorities, including the FDA and similar health authorities in foreign countries to market and sell our products in those countries. These regulatory agencies regulate the
marketing, manufacturing, labeling, packaging, advertising, sale and distribution of medical devices. The FDA enforces additional regulations regarding the safety of X-ray emitting devices. Our products are currently regulated by such authorities
and certain of our new products will require approval by, or marketing clearance from, various governmental authorities, including the FDA. Various states also impose similar regulations.

The FDA review process typically requires extended proceedings pertaining to the safety and efficacy of new products. A
510(k) application is required in order to market a new or modified medical device. If specifically required by the FDA, a pre-market approval, or PMA, may be necessary. Such proceedings, which must be completed prior to marketing a new medical
device, are potentially expensive and time consuming. They may delay or hinder a products timely entry into the marketplace. Moreover, there can be no assurance that the review or approval process for these products by the FDA or any other
applicable governmental authority will occur in a timely fashion, if at all, or that additional regulations will not be adopted or current regulations amended in such a manner as will adversely affect us. The FDA also oversees the content of
advertising and marketing materials relating to medical devices which have received FDA clearance. Failure to comply with the FDAs advertising guidelines may result in the imposition of penalties.

We are also be subject to other federal, state and local laws, regulations and recommendations relating to safe working conditions,
laboratory and manufacturing practices. The extent of government regulation that might result from any future legislation or administrative action cannot be accurately predicted. Failure to comply with regulatory requirements could have a material
adverse effect on our business.

Similar to the FDA review process, the EU review process typically requires extended
proceedings pertaining to the safety and efficacy of new products. Such proceedings, which must be completed prior to marketing a new medical device, are potentially expensive and time consuming and may delay or prevent a products entry into
the marketplace.

##### Table of Contents

Our business may be negatively affected if we do not continue to adapt to rapid technological change,
evolving industry standards and new product introductions.

The market for our products is characterized by rapid and
significant technological change, evolving industry standards and new product introductions. Our products require significant planning, design, development and testing which requires significant capital commitments and investment by us. There can be
no assurance that our products or proprietary technologies will not become noncompetitive or obsolete as a result of technological change, evolving industry standards or new product introductions or that we will be able to generate any economic
return on our investment in product development. If our products or technologies become noncompetitive or obsolete, our business could be negatively affected.

Our profitability may be negatively impacted by adverse general macroeconomic conditions in the geographic markets in which we sell our products.

Our profitability depends in part on the varying economic and other conditions of the global dental market, which in turn is impacted by
general macroeconomic conditions in the geographic markets in which we sell our products. Growth in the global dental market over the past few years has been driven by a number of factors, including a growth in disposable income, a shift towards
private pay, a greater need for dental preventative care and an increased emphasis on aesthetics. Demand for our products would be negatively impacted by a decline in the economy in general, including interest rate and tax changes, that impact the
financial strength of our customers, as well as by changes in the economy in general that reduce disposable income among dental consumers in the markets we sell our products, which would in turn reduce the demand for preventative and aesthetic
dental services.

The recent disruptions in the overall world economy and financial markets could reduce disposable income
among dental consumers and negatively affect the demand for dental services, which could be harmful to our financial position and results of operations. Furthermore, there can be no assurances that government responses to the disruptions in the
financial markets will stabilize the markets or increase liquidity and the availability of credit for our customers. Difficult economic conditions may also result in a higher rate of losses on our accounts receivable. As a result, our business,
results of operations or financial condition could be materially adversely affected.

In the last two fiscal years, our
business was impacted by the weak global economy, which resulted in a challenging environment for selling dental technologies. We have observed that some dentists are postponing investments in equipment.

We are dependent upon a limited number of distributors for a significant portion of our revenue, and loss of these key distributors could result in
a loss of a significant amount of our revenue.

Historically, a substantial portion of our revenue has come from a
limited number of distributors. For example, Patterson Dental Company, Inc. accounted for 30% of revenue for the fiscal year ended September 30, 2010. In addition, 15% of our revenue for the fiscal year ended September 30, 2010, was
attributable to sales to Henry Schein, Inc. It is anticipated that Patterson and Henry Schein will continue to be the largest contributors to our revenue for the foreseeable future. There can be no assurance that Patterson and Henry Schein will
purchase any specified minimum quantity of products from us or that they will continue to purchase any products at all. If Patterson or Henry Schein ceases to purchase a significant volume of products from us, it could have a material adverse effect
on our results of operations and financial condition.

Competition in the markets for our products is intense, and we may not be able to
compete effectively.

Competition relating to our current products is intense and includes various companies, both
within and outside of the United States. We anticipate that competition for our future products will also be intense and include various companies, both within and outside of the United States, Asia and Europe. Our competitors and potential
competitors include large companies with substantially greater financial, sales and marketing, and technical resources, larger and more experienced research and development staffs, more extensive physical facilities and substantially greater
experience in obtaining regulatory approvals and in marketing products than we have. In addition, we cannot assure you that our competitors are not currently developing, or will not attempt to develop, technologies and products that are more
effective than those being developed by us or that would otherwise render our existing and new technology and products obsolete or noncompetitive. We may not be able to compete successfully and may lose market share to our competitors.

Our failure to obtain issued patents and, consequently, to protect our proprietary technology could hurt our competitive position.

Our success will depend in part on our ability to obtain and enforce claims in our patents directed to our products,
technologies and processes, both in the United States and in other countries. Risks and uncertainties that we face with respect to our patents and patent applications include the following:



| |  |  | the pending patent applications that we have filed, or to which we have exclusive rights, may not result in issued patents or may take longer than we
expect to result in issued patents;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our revenue and operating results are likely to fluctuate.

Our
quarterly operating results have varied in the past, and our operating results are likely to continue to fluctuate in the future. These variations result from a number of factors, many of which are substantially outside of our control, including:



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



| |  |  | timing of industry tradeshows, particularly the International Dental Show;

| | - |  | --------------------------



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

Our financial results may be adversely affected by fluctuations in foreign currency exchange rates.

We are exposed to currency exchange risk with respect to the U.S. Dollar in relation to the Euro, because a large portion of our
revenue and expenses are denominated in Euros. In addition, we have an increasing portion of revenue and expenses denominated in other foreign currencies, e.g. Yen, Australian Dollar, and Yuan Renminbi. While we enter into hedging arrangements to
protect our business against certain currency fluctuations, these hedging arrangements from time to time do not provide comprehensive protection. We monitor changes in our exposure to exchange rate risk that result from changes in our situation. If
we do not enter into effective hedging arrangements in the future, our results of operations and prospects could be materially and adversely affected.

Our hedging transactions may expose us to loss or limit our potential gains.

As part of our risk management program, we use foreign currency exchange forward contracts. While intended to reduce the effects of exchange rate fluctuations, these transactions may limit our
potential gains or expose us to loss. Should our counterparties to such transactions or the sponsors of the exchanges through which these transactions are offered fail to honor their obligations due to financial distress or otherwise, we would
be exposed to potential losses or the inability to recover anticipated gains from these transactions.

We enter into foreign
currency exchange forward contracts as economic hedges of trade commitments or anticipated commitments denominated in currencies other than the functional currency to mitigate the effects of changes in currency rates. Although we do not enter
into these instruments for trading purposes or speculation, and although our management believes all of these instruments are economically effective as hedges of underlying physical transactions, these foreign exchange commitments are dependent on
timely performance by our counterparties. Their failure to perform could result in our having to close these hedges without the anticipated underlying transaction and could result in losses if foreign currency exchange rates have changed.

Our indebtedness could have material adverse consequences for our business, cash flow, financial
condition and results of operations.

We have total bank debt to unrelated parties of $370.7 million as of
September 30, 2010. This level of indebtedness, combined with our other financial obligations and contractual commitments, could have important consequences to our business. For example, it could:



| |  |  | increase the risk that we would be unable to generate cash sufficient to pay amounts due on our indebtedness;
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | make us more vulnerable to adverse changes in general economic, industry and competitive conditions and to adverse changes in government regulation;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, including any indebtedness we may incur
in the future, thereby reducing the availability of our cash flows to fund working capital, capital expenditures, research and development, acquisitions and other general corporate purposes;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;
| | - |  | --------------------------------------------------------------------------------------------------------------------



| |  |  | place us at a competitive disadvantage compared to our competitors that have less debt; and
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | limit our ability to borrow additional amounts or to sell capital stock for working capital, capital expenditures, research and development,
acquisitions, debt service requirements or other general corporate purposes.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Any of these factors could
have a material adverse effect on us.

Restrictive covenants and conditions contained in our senior credit agreement impose operating
and financial restrictions on our business.

Our senior credit agreement contains a number of restrictive covenants and
conditions that impose operating and financial restrictions on our business, including restrictions on our ability to take actions that may be in the best interests of the business. These restrictions and conditions include a mandatory prepayment on
a change in control or sale of all or substantially all assets, as well as significant restrictions on mergers and on any business acquisition. Other covenants limit changes to our business, lending activities, investments including joint ventures,
further indebtedness, and the payment of dividends and capital share redemptions. The financial covenants require that we maintain a debt coverage ratio of consolidated total net debt to consolidated adjusted EBITDA of no more than 2.50 to 1, and a
cash interest coverage ratio of consolidated adjusted EBITDA to cash interest costs of 4.00 to 1 or greater. Failure to comply with these covenants will result in a default under the terms of our senior credit agreement and could result in
acceleration of this indebtedness. For more information concerning compliance with these covenants, please see Item 7. Managements Discussion and Analysis of Financial Conditions and Results of Operations  Liquidity and Capital
Resources.

If we lose our key management personnel or are unable to attract and retain qualified personnel, it could adversely affect
our results of operations or delay or hurt our research and product development efforts.

Our success is dependent, in
part, upon our ability to hire and retain management, sales, technical, research and other personnel who are in high demand and are often subject to competing employment opportunities. It is possible that the loss of the services of one or a
combination of our senior executives or key managers could have an adverse effect on our operations.

We may experience difficulties
managing our growth, which could adversely affect our results of operations.

It is expected that we will grow in
certain areas of our operations as we develop and, assuming receipt of the necessary regulatory approvals, market our products. We will therefore need to recruit personnel, particularly sales and marketing personnel, and expand our capabilities,
which may strain our managerial, operational, financial and other resources. To compete effectively and manage our growth, we must:



| |  |  | train, manage, motivate and retain a growing employee base;
| | - |  | -----------------------------------------------------------



15



---

##### Table of Contents

| |  |  | accurately forecast demand for, and revenue from, our product candidates; and
| | - |  | -----------------------------------------------------------------------------



| |  |  | expand existing operational, financial and management information systems to support our development and planned commercialization activities and the
multiple locations of our offices.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our failure to manage these challenges effectively could materially harm
our business.

Since we operate in markets outside of the United States and Europe, we are subject to additional risks.

We anticipate that sales outside of the United States and Europe will continue to account for a significant percentage
of our revenue. Such revenue is subject to a number of uncertainties, including, but not limited to, the following:



| |  |  | economic and political instability;
| | - |  | -----------------------------------



| |  |  | import or export licensing requirements;
| | - |  | ----------------------------------------



| |  |  | trade restrictions;
| | - |  | -------------------



| |  |  | longer payment cycles;
| | - |  | ----------------------



| |  |  | unexpected changes in regulatory requirements and tariffs;
| | - |  | ----------------------------------------------------------



| |  |  | fluctuations in currency exchange rates;
| | - |  | ----------------------------------------



| |  |  | potentially adverse tax consequences; and
| | - |  | -----------------------------------------



| |  |  | potentially weak protection of intellectual property rights.
| | - |  | ------------------------------------------------------------

These risks may impair our ability to generate revenue from our sales efforts. In addition, many countries outside of the United States
and Europe have their own regulatory approval requirements for the sale of products. As a result, the introduction of new products into, and our continued sale of existing products in, these markets could be prevented, and/or costly and/or
time-consuming, and we cannot assure you that we will be able to obtain the required regulatory approvals on a timely basis, if at all.

We may be exposed to liabilities under the Foreign Corrupt Practices Act, and any determination that we violated the Foreign Corrupt Practices Act
could have a material adverse effect on our business.

To the extent that we operate outside the United States, we are
subject to the Foreign Corrupt Practices Act (the FCPA) which generally prohibits U.S. companies and their intermediaries from bribing foreign officials for the purpose of obtaining or keeping business or otherwise obtaining
favorable treatment. In particular, we may be held liable for actions taken by our strategic or local partners even though such partners are foreign companies that are not subject to the FCPA. Any determination that we violated the FCPA could result
in sanctions that could have a material adverse effect on our business.

We may be a party to legal actions that are not covered by
insurance.

We may be a party to a variety of legal actions, such as employment and employment discrimination-related
suits, employee benefit claims, breach of contract actions, tort claims, stockholder suits, including securities fraud, governmental investigations and intellectual property related litigation. In addition, because of the nature of our business, we
are subject to a variety of legal actions relating to our business operations. Although we have maintained insurance coverage for some of these potential liabilities, we cannot assure you that such insurance coverage will continue to be available
or, if available, that it can be obtained in sufficient amounts or at reasonable cost or that it will be sufficient to cover any claims that may arise. Other potential liabilities may not be covered by insurance, insurers may dispute coverage, or
the amount of insurance may not be sufficient to cover the damages awarded. In addition, certain types of damages, such as punitive damages, may not be covered by insurance and/or insurance coverage for all or certain forms of liability may become
unavailable or prohibitively expensive in the future.

##### Table of Contents

We are dependent upon a limited number of suppliers for critical components. If these suppliers delay
or discontinue the manufacture of these components, we may experience delays in shipments, increased costs and cancellation of orders for our products.

We rely on key suppliers for various critical components and procure certain components from outside sources which are sole suppliers. The availability and prices of these components may be subject to
change due to interruptions in production, changing market conditions and other events. Any delays in delivery of or shortages in these components could interrupt and delay manufacturing of our products and result in the cancellation of orders for
our products. In addition, these suppliers could discontinue the manufacture or supply of these components at any time. We may not be able to identify and integrate alternative sources of supply in a timely fashion or at all. Any transition to
alternate suppliers may result in delays in shipment and increased expenses and may limit our ability to deliver products to our customers. If we are unable to develop reasonably-priced alternative sources in a timely manner, or if we encounter
delays or other difficulties in the supply of such products and other materials from third parties, our business and results of operations may be harmed. In past years, semiconductors have been subject to significant price fluctuations.

While we have, in the past, attempted to mitigate the effects of such potential fluctuations, we cannot assure you that we will continue
to do so or that we will be able to successfully mitigate the effect of future price increases on our results of operations and financial condition. See Item 1 Business  Manufacturing and Suppliers.

Our profitability could suffer if third parties infringe upon our proprietary technology.

Our profitability could suffer if third parties infringe upon our intellectual property rights or misappropriate our technologies and
trademarks for their own businesses. To protect our rights to our intellectual property, we rely on a combination of patent and trademark law, trade secret protection, confidentiality agreements and contractual arrangements with our employees,
strategic partners and others. We cannot assure you that any of our patents, any of the patents of which we are a licensee or any patents which may be issued to us or which we may license in the future, will provide us with a competitive advantage
or afford us protection against infringement by others, or that the patents will not be successfully challenged or circumvented by third parties, including our competitors. The protective steps we have taken may be inadequate to deter
misappropriation of our proprietary information. We may be unable to detect the unauthorized use of, or take appropriate steps to enforce, our intellectual property rights. Effective patent, trademark and trade secret protection may not be available
in every country in which we will offer, or intend to offer, our products. Any failure to adequately protect our intellectual property could devalue our proprietary content and impair our ability to compete effectively. Further, defending our
intellectual property rights could result in the expenditure of significant financial and managerial resources.

Our products may
infringe on the intellectual property rights of others.

Litigation may be necessary to enforce our patents or to
defend against any claims of infringement of patents owned by third parties that are asserted against us. In addition, we may have to participate in one or more interference proceedings declared by the United States Patent and Trademark Office, the
European Patent Office or other foreign patent governing authorities, to determine the priority of inventions, which could result in substantial costs.

If we become involved in litigation or interference proceedings, we may incur substantial expense, and the proceedings may divert the attention of our technical and management personnel, even if we
ultimately prevail. An adverse determination in proceedings of this type could subject us to significant liabilities, allow our competitors to market competitive products without obtaining a license from us, prohibit us from marketing our products
or require us to seek licenses from third parties that may not be available on commercially reasonable terms, if at all. If we cannot obtain such licenses, we may be restricted or prevented from commercializing our products.

The enforcement, defense and prosecution of intellectual property rights, including the United States Patent and Trademark Offices,
the European Patent Offices and other foreign patent offices interference proceedings, and related legal and administrative proceedings in the United States and elsewhere, involve complex legal and factual questions. As a result, these
proceedings are costly and time-consuming, and their outcome is uncertain. Litigation may be necessary to:



| |  |  | assert against others or defend us against claims of infringement;
| | - |  | ------------------------------------------------------------------



| |  |  | enforce patents owned by, or licensed to us from, another party;
| | - |  | ----------------------------------------------------------------



| |  |  | protect our trade secrets or know-how; or
| | - |  | -----------------------------------------



| |  |  | determine the enforceability, scope and validity of our proprietary rights or the proprietary rights of others.
| | - |  | ---------------------------------------------------------------------------------------------------------------

Changes in the healthcare industry could adversely affect our business.

The healthcare industry has undergone, and is in the process of undergoing, significant changes driven by efforts to reduce costs. These
changes include legislative healthcare reform, the reduction of spending budgets by government and private insurance programs, such as Medicare, Medicaid and corporate health insurance plans; trends toward managed care; consolidation of healthcare
distribution companies; consolidation of healthcare manufacturers; collective purchasing



17

##### Table of Contents

arrangements and consolidation among office-based healthcare practitioners; and changes in reimbursements to customers. Some of these potential changes may cause a decrease in demand for and/or
reduce the prices of our products. These changes could adversely affect our revenues and profitability. In addition, similar legislative efforts in the future could adversely impact our business.

Product liability claims exposure could be significant.

We may face exposure to product liability claims and recalls for unforeseen reasons from consumers, distributors or others. We may experience material product liability losses in the future, and we may
incur significant costs to defend these claims. In addition, if any of our products are or are alleged to be defective; we may be required to participate in a recall involving those products. End-users of our products may look to us for contribution
when faced with product recalls or product liability claims. Although we have maintained insurance coverage related to product liability claims, we cannot assure you that product liability insurance coverage will continue to be available or, if
available, that it can be obtained in sufficient amounts or at reasonable cost or that it will be sufficient to cover any claims that may arise. We may not maintain any insurance relating to potential recalls of our products. A successful product
liability claim brought against us in excess of available insurance coverage or a requirement to participate in any product recall could reduce our profits and/or impair our financial condition, and damage our reputation.

Product warranty claims exposure could be significant.

We generally warrant each of our products against defects in materials and workmanship for a period of one year from the date of shipment plus any extended warranty period purchased by the customer. The
future costs associated with providing product warranties could be material. A successful warranty claim brought against us could reduce our profits and/or impair our financial condition, and damage our reputation.

Adverse publicity regarding the safety of our technology or products could negatively impact us.

Despite any favorable safety tests that may be completed with respect to our products, adverse publicity regarding application of X-ray
products or other products being developed or marketed by others could negatively affect us. If other researchers studies raise or substantiate concerns over the safety of our technology approach or product development efforts generally, our
reputation could be harmed, which would adversely impact our business.

Inadequate levels of reimbursement from governmental or other
third-party payers for procedures using our products may cause our revenue to decline.

Third-party payers, including
government health administration authorities, private health care insurers and other organizations regulate the reimbursement of fees related to certain diagnostic procedures or medical treatments. Third-party payers are increasingly challenging the
price and cost-effectiveness of medical products and services. While we cannot predict what effect the policies of government entities and other third-party payers will have on future sales of our products, there can be no assurance that such
policies would not cause our revenue to decline.

We have developed and must continue to maintain internal controls.

Effective internal controls are necessary for us to provide assurance with respect to our financial reports and to effectively prevent
fraud. If we cannot provide reasonable assurance with respect to our financial reports and effectively prevent fraud, our operating results could be harmed. The Sarbanes-Oxley Act of 2002 requires us to furnish a report by management on internal
control over financial reporting, including managements assessment of the effectiveness of such control. Internal control over financial reporting may not prevent or detect misstatements because of its certain limitations, including the
possibility of human error, the circumvention or overriding of controls, or fraud. As a result, even effective internal controls may not provide reasonable assurances with respect to the preparation and presentation of financial statements. In
addition, projections of any evaluation of effectiveness of internal control over financial reporting to future periods are subject to the risk that the control may become either obsolete or inadequate as a result of changes in conditions, or that
the degree of compliance with the policies or procedures may deteriorate. If we fail to maintain adequate internal controls, including any failure to implement required new or improved controls, or if we experience difficulties in implementing new
or revised controls, our business and operating results could be harmed and we could fail to meet our reporting obligations.

Risks Related to Our Common Stock

Future sales of our common stock may cause the market price for our common stock to decline even if our business is doing well.

Future sales by us or by our existing stockholders of substantial amounts of our common stock in the public market, or the perception that
these sales may occur, could cause the market price of our common stock to decline.

Sirona Holdings Luxco SCA, or
Luxco, requested that we register common stock that they own under the Securities Act pursuant to contractual registration rights, and on August 19, 2008, we filed a registration statement providing for the potential resale of up to
36,972,480 shares of our common stock. In August 2009, December 2009, and February 2010, Luxco sold 8,625,000, 7,100,000, and 7,000,000 shares, respectively, pursuant to underwritten public offerings. We cannot predict the size or timing of actual
future sales of our common stock or the effect, if any, that future sales of shares of our common stock, or the expectation of such sales, would have on the market price of our common stock.

Our largest stockholder can exert influence over us and may have interests that diverge from yours.

At September 30, 2010, Luxco owned approximately 25% of our outstanding common stock. As a result, Luxco has the voting power to significantly influence our policies, business and affairs, and the
outcome of any corporate transaction or other matter, including mergers, consolidations and the sale of all, or substantially all, of our assets. This concentration in ownership may have the effect of delaying, deterring, or preventing a change in
control that otherwise could result in a premium in the price of our common stock.

Luxco may have interests that diverge from
those of other holders of our common stock. As a result, Luxco may vote the shares it owns or otherwise cause us to take actions that may conflict with your best interests as a stockholder, which could adversely affect our results of operations and
the trading price of our common stock.

Certain provisions of our certificate of incorporation and bylaws and Delaware law could
discourage, delay, or prevent a merger or acquisition at a premium price.

The provisions of our certificate of
incorporation and bylaws may also deter, delay or prevent a third-party from acquiring us. These provisions include:



| |  |  | limitations on the ability of stockholders to amend our charter documents, including stockholder supermajority voting requirements;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | the authority of the board of directors to adopt amendments to our bylaws without shareholder approval;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | the inability of stockholders to act by written consent or to call special meetings;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | a classified board of directors with staggered three-year terms;
| | - |  | ----------------------------------------------------------------



| |  |  | advance notice requirements for nominations for election to the board of directors and for stockholder proposals; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | the authority of our board of directors to issue, without stockholder approval, up to 5,000,000 shares of preferred stock with such terms as the board
of directors may determine and to issue additional shares of our common stock.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We are also subject to the
protections of Section 203 of the Delaware General Corporation Law, which prevents us from engaging in a business combination with a person who acquires at least 15% of our common stock for a period of three years from the date such person
acquired such common stock, unless board or stockholder approval were obtained.

In addition, in the event of a change
of control as defined in our senior credit agreement, we may be required to, among other things, repay all of our obligations outstanding under the senior credit agreement, with interest thereon, which could materially adversely impact the
value of our common stock.

These provisions could have the effect of delaying, deferring or preventing a change in control of
our company, discourage others from making tender offers for our shares, lower the market price of our stock or impede the ability of our stockholders to change our management, even if such changes would be beneficial to our stockholders.

The market price of our common stock may fluctuate significantly, and this may make it difficult for
holders to resell our common stock when they want or at prices that they find attractive.

The price of our common
stock on the NASDAQ Global Select Market constantly changes. We expect that the market price of our common stock will continue to fluctuate. The market price of our common stock may fluctuate as a result of a variety of factors, many of which are
beyond our control. These factors include:



| |  |  | changes in market conditions;
| | - |  | -----------------------------



| |  |  | quarterly variations in our operating results;
| | - |  | ----------------------------------------------



| |  |  | operating results that vary from the expectations of management, securities analysts and investors;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | changes in expectations as to our future financial performance;
| | - |  | ---------------------------------------------------------------



| |  |  | announcements of strategic developments, significant contracts, acquisitions and other material events by us, our competitors, or our distribution
partners;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the operating and securities price performance of other companies that investors believe are comparable to us;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | future sales of our equity or equity-related securities;
| | - |  | --------------------------------------------------------



| |  |  | changes in the economy and the financial markets;
| | - |  | -------------------------------------------------



| |  |  | departures of key personnel;
| | - |  | ----------------------------



| |  |  | changes in governmental regulations; and
| | - |  | ----------------------------------------



| |  |  | geopolitical conditions, such as acts or threats of terrorism or military conflicts.
| | - |  | ------------------------------------------------------------------------------------

In addition, in recent years, the stock market in general has experienced extreme price and volume fluctuations. This volatility has had
a significant effect on the market price of securities issued by many companies for reasons often unrelated to their operating performance. These broad market fluctuations may adversely affect the market price of our common stock, regardless of our
operating results.

On November 15, 2010,
there were approximately 95 holders of record of the Companys common stock. However, the Company believes that the number of beneficial owners of its common stock is substantially higher.

In connection with the Exchange, Schick declared a $2.50 per share dividend to stockholders of record as of the close of business on
June 19, 2006. Since the Exchange, Sirona has not paid any dividends to holders of its common stock. The Company may consider paying dividends in the future, but currently has no plans to do so. The payment of dividends is within the discretion
of the Board of Directors and will depend upon the Companys earnings, its capital requirements, financial condition and other relevant factors. The payment of dividends is restricted by the terms of our senior credit facility.

No repurchases were made by the Company during the current fiscal year.

|(2) | On September 25, 2005, Schick, a Delaware Corporation, which on June 20, 2006 was renamed Sirona Dental Systems, Inc. (Sirona or the
Company), entered into an agreement with Luxco and Sirona Holding providing for the issuance of 36,972,480 shares of Schick common stock to Luxco in exchange for Luxcos entire economic interest in Sirona Holding, which consisted of
all of the issued and outstanding share capital of Sirona Holding and the existing indebtedness of Sirona Holding owed to Luxco in the principal amount of Euro 151 million plus accrued interest (the Exchange). The Exchange closed on
June 20, 2006. For accounting purposes, the Exchange is accounted for as a reverse acquisition of Schick by Sirona Holding. The historical financial statements of Sirona Holding and its predecessor and the historical financial statements of the
Company, and the acquisition by Sirona Holding of the assets and liabilities of Schick are accounted for under the purchase method of accounting. Results of operations of Schick and its wholly owned subsidiary have been included in financial
statements from June 20, 2006, the effective date of the Exchange.

|ITEM 7. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

The following discussion should be read in conjunction with the Consolidated Financial Statements included elsewhere in this Report. This
discussion contains forward-looking statements based on current expectations that involve risks and uncertainties. Actual results and the timing of certain events may differ significantly from those projected in such forward-looking statements due
to a number of factors, including those set forth in Results of Operations in this Item and elsewhere in this Report. Except as otherwise disclosed all amounts are reported in U.S. Dollars ($).

Overview

Sirona Dental
Systems Inc. (Sirona, the Company, we, us, and our refer to Sirona Dental Systems, Inc. and its consolidated subsidiaries and their predecessors) 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 approximately 130 years ago, the first dental X-ray unit approximately 100 years ago, the first dental computer-aided design/computer-aided
manufacturing (CAD/CAM) system 25 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 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. Due to the international nature of the Companys business, movements in global foreign exchange rates have a significant effect on financial results.

The U.S. market is the largest individual market for Sirona, followed by Germany. Between fiscal years 2004 and 2010, the Company
increased U.S. revenues from $88.2 million to $239.5 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 commencing
at the beginning of the extension of the exclusivity period in fiscal year 2008.

In addition to strong U.S. market growth,
Sirona has pursued expansion in non-U.S. and non-German markets. Between fiscal years 2004 and 2010, the Company increased revenues in non-U.S. and non-German markets from $190.9 million to $382.4 million. To support this growth, Sirona expanded its
local presence and distribution channels by establishing sales and service locations e.g. in Japan, Australia, China, Korea, Italy, France, and the UK. The expansion helped to increase market share but also contributed to higher SG&A expenses.

The weak global economy in 2009 resulted in a challenging environment for selling dental technology, which impacted
Sironas revenue and financial performance. In fiscal year 2009, total Company revenues increased 1.3% on a constant currency basis, with successful new product launches, including the CEREC AC, partially offsetting the weak economic
trends. To deal with the weakened economy, the Company undertook certain targeted actions in 2009 to reduce operating costs and to increase efficiency on a longer term basis.

While the global economy improved in 2010, it did not fully recover and we continued to experience economic headwinds in fiscal year
2010. Despite these headwinds, Sirona increased revenues by 7.9% constant currency in fiscal year 2010, with strong growth in our Imaging segment driven by our Galileos 3D imaging system. In fiscal year 2010, our net

income benefited from this revenue growth, but also from margin expansion, expense management initiatives, and debt reduction. Our targeted cost-saving actions were on plan, and we started
reinvesting some of these cost savings in the second half of fiscal year 2010. Cash flow from operations was strong, mainly driven by higher cash flow from operations and lower interest payments.

Significant Factors that Affect Sironas Results of Operations

The MDP Transaction and the Exchange

On June 30, 2005, Sirona
Holdings Luxco S.C.A. (Luxco), a Luxembourg-based holding entity owned by funds managed by Madison Dearborn Partners, Beecken Petty OKeefe, management and employees of Sirona, obtained control over the Sirona business. The
transaction was effected by using new legal entities, Sirona Holding GmbH (formerly Blitz 05-118 GmbH) and its wholly owned subsidiary Sirona Dental Services GmbH, to acquire 100% of the interest in Sirona Dental Systems Beteiligungs- und
Verwaltungs GmbH, the former parent of the Sirona business through a leveraged buy-out transaction (the MDP Transaction).

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 result 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 currencies vary depending on the country of operation. For the fiscal year ended September 30, 2010, approximately 45% of Sironas revenue and approximately 71% of its
expenses were in Euro. During the periods under review, the U.S. Dollar/Euro exchange rate has fluctuated significantly, thereby impacting Sironas financial results. Between October 1, 2007 and September 30, 2010, the U.S.
Dollar/Euro exchange rate used to calculate items included in Sironas financial statements varied from a low of $1.1919 to a high of $1.6017. Although Sirona does not apply hedge accounting, Sirona has entered into foreign exchange forward
contracts to manage foreign currency exposure. As of September 30, 2010, these contracts had notional amounts totaling $33.5 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 above and
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 exchange rate for the fiscal year ended September 30, 2010, was $1.35730 and varied
from $1.48990 to $1.22161. For the fiscal year ended September 30, 2009, the weighted average quarterly exchange rate used in converting Euro denominated revenues into U.S. Dollars in the Companys financial statements prepared in
accordance with U.S. GAAP was $1.35475 based on the average of the exchange rates for the individual quarters included within the year.

Loans made to Sirona under the Senior Facilities Agreement entered into on 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;
| | - |  | ------------------------------------------------------------------



| |  |  | timing of industry tradeshows, particularly the International Dental Show;
| | - |  | --------------------------------------------------------------------------



| |  |  | 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;
| | - |  | ------------------------------------



| |  |  | 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 future performance.

Effective
Tax Rate

Sironas effective tax rate may vary significantly from period to period. As a global enterprise, the
Companys effective tax rate is affected by many factors. These factors include, but are not limited to, the actual distribution of profits across the different jurisdictions, tax planning initiatives, varying local tax rates, tax
characteristics of income, as well as the timing and deductibility of expenses for tax purposes. The distribution of lower-taxed foreign earnings to the U.S. would generally increase the Companys effective tax rate.

Fiscal Year Ended September 30, 2010 compared to Fiscal Year Ended September 30, 2009

Revenue

Revenue for the fiscal year ended September 30, 2010 was $770.3 million, an increase of $57.0 million, or 8.0%, as compared with the fiscal year ended September 30, 2009. On a constant currency
basis, adjusting for the fluctuations in the U.S. Dollar/Euro exchange rate, total revenue increased by 7.9%. By segment, Imaging Systems increased 11.4% (up 11.3% on a constant currency basis), Instruments increased 7.3% (up 7.1% on a constant
currency basis), Treatment Centers increased 6.3% (up 6.1% on a constant currency basis), and CAD/CAM Systems increased 6.1% (up 6.0% on a constant currency basis). We were able to grow our revenues due to the demand for our innovative products, and
we continue to benefit from our global sales and service infrastructure. Our products enable dental professionals to improve their clinical results and to increase the profitability of their practices.

Imaging segment revenues increased 11.4%, benefiting from the continued strong demand for digital products. Sales growth was particularly
driven by the success of our Galileos 3D panoramic unit helped by the CEREC meets Galileos offering. Instruments segment revenues increased 7.3% and benefited from strong hygiene sales and high volume projects in several non-US markets.

The Treatment Centers segment revenues increased 6.3%. Continued strong Teneo sales as well as larger volume projects in non-US,
non-European markets contributed to this development.

Dental CAD/CAM Systems segment revenues grew 6.1%, driven by the
continued demand for this technology. The CEREC AC trade-in program for existing CEREC users supported the growth.

Revenue in
the U.S. for the fiscal year ended September 30, 2010 was up 8.3% compared to prior year. Revenue growth was mainly driven by the Imaging segment and the success of Galileos. Revenue outside the U.S. increased by 7.9%. On a constant currency
basis, adjusting for the fluctuations in the U.S. Dollar/Euro exchange rate, these revenues increased by 7.7%. Revenue growth was particularly strong in the Asia Pacific region and the Middle East. European markets showed solid performance.

Revenue growth on a constant currency basis was mainly volume driven. Prices in general remained stable, with the exception
of pricing pressure and product mix shifts in the 2D and 3D panoramic imaging product lines.

Cost of Sales

Cost of sales for the fiscal year ended September 30, 2010 was $371.3 million, a increase of $4.1 million, or 1.1%, as compared with the fiscal year ended September 30, 2009. Gross profit as a
percentage of revenue was 51.8% compared to 48.5% in the prior year. Cost of sales included amortization and depreciation expense resulting from the step-up to fair values of tangible and intangible assets of $56.1 million as well as non-cash
share-based compensation expense of $0.1 million for the fiscal year ended September 30, 2010, compared to amortization and depreciation expense resulting from the step-up to fair values of tangible and intangible assets of $66.1 million and
non-cash share-based compensation expense of $0.3 million for the fiscal year ended September 30, 2009. Excluding these amounts, cost of sales as a percentage of revenue was 40.9% for the fiscal year ended September 30, 2010, compared with
42.2% for the fiscal year ended September 30, 2009, and therefore gross profit as a percentage of revenue was 59.1% compared to 57.8% in the prior year. The expansion in the gross profit margin was mainly due to product and regional mix and
showed in all segments.

Selling, General and Administrative

For the fiscal year ended September 30, 2010, SG&A expense was $235.9 million, a increase of $10.6 million, or 4.7%, as compared
with the fiscal year ended September 30, 2009. SG&A expense included amortization and depreciation resulting from the step-up to fair values of tangible and intangible assets of $3.3 million as well as non-cash share-based compensation
expense in the amount of $13.3 million for the fiscal year ended September 30, 2010, compared with $4.0 million and $14.9 million, respectively, for the fiscal year ended September 30, 2009. Excluding these amounts, as a percentage of
revenue, SG&A expense slightly decreased to 28.5% for the fiscal year ended September 30, 2010 as compared with 28.9% for the fiscal year ended September 30, 2009. The increase in the absolute SG&A expense is mainly driven by
investments in sales and service infrastructure in international markets.

amount of $0.2 million for the fiscal year ended September 30, 2010, compared with $0.5 million for the fiscal year ended September 30, 2009. Excluding this amount, as a percentage of revenue, R&D expense increased to 6.0% for the
fiscal year ended September 30, 2010, compared to 5.6% for the fiscal year ended September 30, 2009.

The increase
of the absolute R&D expense was primarily driven by the timing of new product launches.

Loss/(Gain) on Foreign Currency Transactions

Loss on foreign currency transactions for the fiscal year ended September 30, 2010 amounted to $7.2 million compared to a gain of
$1.2 million for the fiscal year ended September 30, 2009. For fiscal year 2010, the loss included an unrealized non-cash foreign currency loss of $5.7 million on the U.S. Dollar denominated deferred income from the translation
adjustment of Pattersons exclusivity payment and an unrealized non-cash foreign currency loss on the U.S. Dollar denominated short term intra-group loans to our Austrian entity of $5.1 million. Excluding these amounts, foreign currency
transactions for fiscal year 2010 resulted in a gain of $3.6 million.

The gain for the fiscal year ended September 30,
2009 included an unrealized non-cash foreign currency gain of $1.5 million on the U.S. Dollar denominated deferred income from the translation adjustment of Patterson ́s exclusivity payment, as well as a non-cash unrealized foreign
currency gain on the U.S. Dollar denominated short term intra-group loans to our Austrian entity of $1.4 million. Excluding these amounts, foreign currency transactions for fiscal year 2009 resulted in a loss of $1.7 million.

(Gain)/Loss on Derivative Instruments

The gain on derivative instruments for the fiscal year ended September 30, 2010, amounted to $6.1 million compared to a loss of $0.2 million for the fiscal year ended September 30, 2009. For the
fiscal year ended September 30, 2010, the gain included an unrealized non-cash gain of $6.4 million on interest swaps, as well as an unrealized non-cash loss on foreign currency hedges of $0.3 million. The loss for the fiscal year ended
September 30, 2009, included an unrealized non-cash loss of $3.8 million on interest swaps, as well as a non-cash gain on foreign currency hedges of $3.7 million.

Interest Expense

Net interest expense for the fiscal year ended
September 30, 2010, was $11.0 million, compared to $22.5 million for the fiscal year ended September 30, 2009. This decrease resulted from lower interest rates and lower overall debt levels.

Other Expenses

In December 2009, Luxco sold 7,100,000 shares pursuant to an underwritten follow-on public offering. The Company incurred $0.4 million of
costs pursuant to the terms of a registration rights agreement.

In February 2010, Luxco sold 7,000,000 shares pursuant to an
underwritten follow-on public offering. The Company incurred $0.4 million of costs pursuant to the terms of a registration rights agreement.

For the fiscal year ended September 30, 2009, Luxco sold 8,625,000 shares in August 2009 pursuant to an underwritten secondary public offering. $0.4 million of costs were incurred by the Company
pursuant to the terms of a registration rights agreement.

Income Tax Provision

For the fiscal years ended September 30, 2010 and 2009, Sirona recorded a profit before income taxes of $115.2 million and $63.3
million, respectively. The average actual effective tax rate for these years was 20.6% and 14.7%, respectively. The income tax provision for the fiscal years ended September 30, 2010 and 2009 was $23.8 and $9.3 million, respectively. The income
tax provision for the fiscal year ended September 30, 2009 included credits of $1.6 million to adjust for prior year items. In addition, a lower level of non tax-deductible items in relation to pre-tax income positively impacted the effective
tax rate for the fiscal year ended September 30, 2009.

Net Income

Sironas net income for the fiscal year ended September 30, 2010 was $91.4 million, an increase of $37.5 million, as compared with the fiscal year ended September 30, 2009. Major
influencing factors on net income were the increase in revenues, lower costs resulting from the effects of restructuring and other cost-savings initiatives, the lower amortization of assets acquired in past business combinations, partially offset by
the increase in the effective tax rate. The effective tax rate for fiscal year 2010 was 20.6%, up from 14.7% in fiscal year 2009. Fiscal year 2010 net income included amortization and depreciation expense resulting from the step-up to fair values of
intangible and tangible assets related to past business combinations (i.e. the Exchange and the MDP Transaction - deal related amortization and depreciation) of $59.5 million ($47.2 million net of tax), unrealized, non-cash foreign currency losses
on the deferred income from the Patterson exclusivity payment of $5.7 million ($4.5 million net of tax), losses on the revaluation of short-term intra-group loans of $5.1 million ($4.0 million net of tax), a gain on interest swaps of $6.4 million
($5.1 million net of tax), a gain on the release of the unused restructuring accrual of $0.8 million ($0.6 million net of tax), and a gain on a sale of a subsidiary of $0.9 million ($0.7 million net of tax).

Sironas net income for the fiscal year ended September 30, 2009 included deal related amortization and depreciation of assets
acquired in past business combinations of $70.1 million ($59.8 million net of tax), currency revaluation gains on the Patterson exclusivity payment of $1.5 million ($1.3 million after tax), a loss on interest swaps of $3.9 million ($3.3 million net
of tax), a gain on the revaluation of short-term intra-group loans of $1.4 million ($1.2 million net of tax), and a gain on the sale of a subsidiary of $3.9 million ($3.3 million net of tax).

Share-based compensation expense was $13.6 million ($10.8 million net of tax) in fiscal year 2010, compared to $15.7 million ($13.4
million net of tax) in fiscal year 2009.

Fiscal Year Ended September 30, 2009 compared to Fiscal Year Ended September 30,
2008

Revenue

Revenue for the fiscal year ended September 30, 2009 was $713.3 million, a decrease of $43.8 million, or 5.8%, as compared with the fiscal year ended September 30, 2008. On a constant currency
basis, adjusting for the fluctuations in the U.S. Dollar/Euro exchange rate, total revenue increased by 1.3%. By segment, CAD/CAM Systems increased 3.4% (up 9.3% on a constant currency basis), Instruments decreased 9.1% (up 0.5% on a constant
currency basis), Treatment Centers decreased 9.7% (flat on a constant currency basis), and Imaging Systems decreased 10.7% (down 5.4% on a constant currency basis).

All segments were impacted by the weak global economy, which resulted in a challenging environment for selling dental technology. In the current slowdown, we are seeing that some dentists are postponing
investments in equipment. At the same time, they continue to demand innovative high tech products that improve their competitive position and increase their practice income; such products in general include CAD/CAM systems, digital imaging and
Galileos 3D imaging systems. In fiscal year 2009, revenues were positively impacted by our new product launches, particularly the CEREC AC and TENEO, orders from the bi-annual international trade show IDS and larger projects from
non-U.S., non-European markets.

Dental CAD/CAM Systems segment revenue growth benefited from the strong global reception of
our new acquisition unit CEREC AC. The CEREC AC trade-in program for existing CEREC users supported the growth.

Despite the
weak economic environment, Sironas Treatment Center revenue was flat on a constant currency basis. The Treatment Centers segment benefited from the TENEO treatment center launch and strong business in non-U.S., non-European markets.

Instruments segment revenue increased 0.5% on a constant currency basis, also impacted by the weak economic conditions.
Instruments benefited from strong hygiene product sales as well as larger projects in several non-U.S. markets.

Imaging
segment revenues were impacted by pricing pressure and the weak economic environment. However, Sirona maintained and in many regions expanded its market share in the segment. 3D imaging systems sales showed a solid performance.

Revenue in the U.S. for the fiscal year ended September 30, 2009 was flat compared to prior year. This overall development was
driven by strong CAD/CAM sales, which was offset by lower sales in other segments.

Revenue outside the U.S. decreased by
8.2%. On a constant currency basis, adjusting for the fluctuations in the U.S. Dollar/Euro exchange rate, these revenues increased by 1.8%, with mixed results among the various countries. Revenue growth was particularly solid in Germany, Japan,
Australia, and some other non-European markets. This solid growth was partly offset by declines in Spain, South Korea, Russia and the UK.

##### Table of Contents

Revenue growth on a constant currency basis was mainly volume driven. Prices in general
remained stable, with the exception of pricing pressure and product mix shifts particularly in the 2D and 3D panoramic imaging product lines.

Cost of Sales

Cost of sales for the fiscal year ended September 30, 2009 was $367.2 million, a decrease of $44.3 million, or 10.8%, as compared
with the fiscal year ended September 30, 2008. Gross profit as a percentage of revenue was 48.5% compared to 45.7% in the prior year. Cost of sales included amortization and depreciation expense resulting from the step-up to fair values of
tangible and intangible assets of $66.1 million as well as non-cash option expense of $0.3 million for the fiscal year ended September 30, 2009, compared to amortization and depreciation expense resulting from the step-up to fair values of
tangible and intangible assets of $85.0 million and non-cash option expense of $0.7 million for the fiscal year ended September 30, 2008. Excluding these amounts, cost of sales as a percentage of revenue was 42.2% for the fiscal year ended
September 30, 2009, compared with 43.1% for the fiscal year ended September 30, 2008, and therefore gross profit as a percentage of revenue was 57.8% compared to 56.9% in the prior year. The increase in gross profit margin was due to
product and regional mix.

Gross profit margins were impacted by the fluctuations in the Euro/U.S. Dollar exchange rate, as
the majority of expenses are Euro denominated. The gross profit margin for the Instrument, Imaging Systems and Treatment Center segments were at or below the prior year levels, while CAD/CAM Systems margins expanded. The Imaging Systems gross profit
margin in fiscal year 2009 was the result of a favorable product mix offset by pricing pressure.

Selling, General and Administrative

For the fiscal year ended September 30, 2009, SG&A expense was $225.4 million, a decrease of $16.9 million,
or 7.0%, as compared with the fiscal year ended September 30, 2008. SG&A expense included amortization and depreciation resulting from the step-up to fair values of tangible and intangible assets of $4.0 million as well as non-cash option
expense in the amount of $14.9 million for the fiscal year ended September 30, 2009, compared with $5.4 million and $13.8 million, respectively, for the fiscal year ended September 30, 2008. Excluding these amounts, as a percentage of
revenue, SG&A expense decreased to 28.9% for the fiscal year ended September 30, 2009 as compared with 29.5% for the fiscal year ended September 30, 2008.

The decrease in SG&A was primarily due to the weaker Euro relative to the U.S. Dollar (as most of the expenses are Euro denominated), partially offset by increased expenses related to our
expanded presence in Japan and Italy, and expenses for IDS. Fiscal year 2009 results benefited from short-term cost savings and deferral initiatives.

Research and Development

R&D expense for the fiscal year ended
September 30, 2009 was $40.6 million, a decrease of $8.1 million, or 16.6%, as compared with the fiscal year ended September 30, 2008.

R&D expense included non-cash stock option expense in the amount of $0.5 million for the fiscal year ended September 30, 2009, compared with $1.0 million for the fiscal year ended
September 30, 2008. Excluding this amount, as a percentage of revenue, R&D expense decreased to 5.6% for the fiscal year ended September 30, 2009, compared to 6.3% for the fiscal year ended September 30, 2008.

The decrease of the absolute R&D expense was primarily driven by the weaker Euro relative to the U.S. Dollar, as most R&D
expenses were Euro denominated, and the timing of new product launches.

Net Other Operating Income and Restructuring Costs

Net other operating income for the fiscal year ended September 30, 2009, was $5.7 million, compared to $10.0
million for the fiscal year ended September 30, 2008. In both periods net other operating income included $10.0 million resulting from the amortization of the deferred income relating to the Patterson exclusivity payment. See Note 14 to our
consolidated financial statements included elsewhere in this report for further information about the Patterson exclusivity payment.

##### Table of Contents

In the fiscal year ended September 30, 2009, net other operating income included a gain
from the sale of a sales and service subsidiary of $3.9 million.

In December 2008, we announced certain actions to reduce
operating costs and to improve the efficiency of our organization. These actions predominantly relate to overhead functions in Germany including increased automation of our processes, the optimization of the supply chain and increased efficiency in
our administrative functions. For the fiscal year ended September 30, 2009, we incurred restructuring and other related costs of $8.2 million, consisting of employee severance pay and benefits and outside consulting fees directly related to the
restructuring plan. Of these costs, $4.3 million have been paid in fiscal year 2009; the residual amount is expected to be paid in the first half of fiscal year 2010. No material increases in expenses or revenue reductions directly related to this
plan are expected going forward. The Company anticipates annual cost savings from these initiatives to be approximately $10 million starting in fiscal year 2010. It is expected that these cost savings will impact future cost of goods sold in all
segments, as well as SG&A and R&D expenses going forward.

The development of restructuring costs in the current
fiscal year is presented in the following table:

Gain on Foreign Currency Transactions

Gain on foreign currency transactions for the fiscal year ended September 30, 2009 amounted to $1.2 million compared to a gain of $8.9 million for the fiscal year ended September 30, 2008. For
fiscal year 2009, the gain mainly included realized and unrealized foreign currency gains due to fluctuations of the U.S. Dollar/Euro and Yen/Euro exchange rate. Additionally, the fiscal year 2009 gain included realized foreign currency gain and
unrealized non-cash foreign currency gain of $1.5 million on the U.S. Dollar denominated deferred income from the translation adjustment of Pattersons exclusivity payment and a non-cash unrealized foreign currency gain on the
U.S. Dollar denominated short term intra-group loans to our Austrian entity of $1.4 million.

The gain for the fiscal
year ended September 30, 2008 included realized foreign currency gain and unrealized non-cash foreign currency gain of $1.4 million on the U.S. Dollar denominated deferred income from the translation adjustment of Pattersons
exclusivity payment, as well as a non-cash foreign currency gain on the U.S. Dollar denominated short term intra-group loans to our Austrian entity of $0.6 million.

Loss on Derivative Instruments

The loss on derivative instruments
for the fiscal year ended September 30, 2009, amounted to $0.1 million compared to a loss of $6.7 million for the fiscal year ended September 30, 2008. For the fiscal year ended September 30, 2009, the loss included an unrealized
non-cash loss of $3.8 million on interest swaps, as well as an unrealized non-cash gain on foreign currency hedges of $3.7 million. The loss for the fiscal year ended September 30, 2008, included an unrealized non-cash loss of $2.1 million on

Interest Expense

Net interest expense for the fiscal year ended September 30, 2009, was $22.5 million, compared to $26.8 million for the fiscal year
ended September 30, 2008. This decrease resulted from variations in the U.S. Dollar/Euro exchange rates, lower interest rates and lower overall debt levels.

Other Expenses

In August 2009, Luxco sold 8,625,000 shares pursuant to an underwritten secondary public offering. $0.4 million of costs were incurred by the Company pursuant to the terms of a registration rights
agreement. For the fiscal year ended September 30, 2008, other expenses related to $0.3 million of real estate transfer taxes.

Income Tax Provision

For the fiscal years ended September 30, 2009 and 2008, Sirona recorded a profit before income taxes and minority interest of $63.3 million and $38.9 million, respectively. The average actual
effective tax rate for these years was 14.7% and 24.0%, respectively. The income tax provision for the fiscal years ended September 30, 2009 and 2008 was $9.3 million, in each year. The income tax provision for the fiscal year ended
September 30, 2009 included credits of $1.6 million to adjust for prior year items. In addition, a lower level of non tax-deductible items in relation to pre-tax income positively impacted the effective tax rate for the fiscal year ended
September 30, 2009.

Net Income

Sironas net income for the fiscal year ended September 30, 2009 was $54.0 million, an increase of $24.4 million, as compared with the fiscal year ended September 30, 2008. Major
influencing factors on net income were the lower effective tax rate, the lower amortization of assets acquired in past business combinations, partially offset by restructuring expenses. The effective tax rate for fiscal year 2009 was 14.7%, down
from 24.0% in fiscal year 2008. Fiscal year 2009 net income included amortization and depreciation expense resulting from the step-up to fair values of intangible and tangible assets related to past business combinations (i.e. the Exchange and the
MDP Transaction - deal related amortization and depreciation) of $70.1 million ($59.8 million net of tax), unrealized, non-cash foreign currency gains on the deferred income from the Patterson exclusivity payment of $1.5 million ($1.3 million net of
tax), gains on the revaluation of short-term intra-group loans of $1.4 million ($1.2 million net of tax) and restructuring expenses of $8.2 million ($7.0 million net of tax), and a gain on a sale of a subsidiary of $3.9 million ($3.3 million net of
tax).

Sironas net income for the fiscal year ended September 30, 2008 included deal related amortization and
depreciation of assets acquired in past business combinations of $90.4 million ($68.7 million net of tax), currency revaluation losses on the Patterson exclusivity payment of $1.4 million ($1.1 million after tax) and a gain on the revaluation of
short-term intra-group loans of $0.6 million ($0.5 million net of tax).

Option expense was $15.7 million ($13.4 million net
of tax) in fiscal year 2009, compared to $15.6 million ($11.9 million net of tax) in fiscal year 2008.

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:

Consolidated
Adjusted EBITDA means for the relevant period: the consolidated income before taxes from ordinary activities plus: (i) any consolidated net finance charges; (ii) any items treated as exceptional or extraordinary items, (iii) any
realized or unrealized gains or losses with respect to borrowings due to movements in exchange rates occurring during such period to the extent the same has not resulted in a cash receipt or payment; (iv) any refinancing costs related to the
senior facility and the Companys former mezzanine facility and any costs related to the 2005 acquisition by MDP; (v) any amount attributable to the amortization of refinancing costs or costs of intangible assets or the depreciation of
tangible assets and current assets or write off of research and development currently in progress incurred in connection with purchase price accounting (fair market value adjustments/step-up); (vi) option or similar non-cash expenses; and
(vii) any non-recurring costs and expenses incurred in order to ensure compliance with Sarbanes-Oxley Act of 2002, less (i) the amount of any profit (and adding the loss) attributable to minority interests; and (ii) the amount of any
profit of any investment or entity (which is not itself a member of the consolidated group) to the extent that the amount of such profit exceeds the amount received in cash. Set forth below is a reconciliation of Consolidated Adjusted EBITDA, as
calculated under the Senior Facilities Agreement, to EBITDA and net income for the 12 months ended September 30, 2010 (in thousands). The measure Consolidated Adjusted EBITDA presented below is calculated in a different manner than EBITDA,
presented elsewhere in this MD&A.

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 $175.7 million for fiscal year 2010 compared to $119.9 million for fiscal year 2009, and $94.7 million for fiscal year 2008. The primary contributing factors to the increase in cash provided by
operating cash flows in fiscal year 2010 were (i) increase in operating income; (ii) improvement in working capital; and (iii) lower interest payments, driven by lower interest rates and lower debt. Net cash provided by operating
activities for fiscal years 2009 and 2008 was impacted by (i) increases in operating income, partly offset by restructuring costs in fiscal year 2009; (ii) income tax refunds received in fiscal year 2009 in the amount of $10.8 million; and
(iii) income tax payments, net of refunds, for the fiscal year and for prior years in the amount of $20.6 million and $43.1 million in fiscal year 2009 and fiscal year 2008, respectively.

Net Cash Used in Investing Activities

Net cash used in investing activities represents cash used for capital expenditures in the normal course of operating activities, financial investments, acquisitions and long-lived asset disposals. The
primary contributors to the investing cash outflow in the periods presented are capital expenditures in the course of normal operating activities and the cash effect from the sale of a subsidiary in fiscal year 2010 as well as fiscal year 2009.

Net cash used in investing activities was $23.2 million for the fiscal year ended September 30, 2010, compared to $16.0
million for the fiscal year ended September 30, 2009, and $36.8 million for the fiscal year ended September 30, 2008. The primary contributors to the investing cash outflow in fiscal year 2010 were (i) capital expenditures and
software developed for sale, related to product launches, partially offset by (ii) proceeds from the sale of a manufacturing subsidiary in Italy, and (iii) a subsequent payment resulting from a purchase price adjustment for a manufacturing
subsidiary in China. The primary contributors in 2009 were investments in special tools and software developed for sale, related to product launches, partially offset by proceeds from the sale of a sales and service subsidiary in Spain; and the
primary contributors in 2008 were investments in special tools and software developed for sale, related to product launches.

Net Cash
Used in Financing Activities

Net cash used in financing activities was $73.9 million for the fiscal year ended
September 30, 2010, compared to net cash used in financing activities of $78.4 million for the fiscal year ended September 30, 2009 and net cash used in financing activities of $8.5 million for the fiscal year ended September 30,
2008. Net cash used in financing activities in fiscal year 2010 relates mainly to the early repayment of senior debt that was originally due in November 2010 eight months ahead of schedule. Net cash used in financing activities in fiscal year 2009
related mainly to the early repayment of senior debt that was originally due in November 2009 six months ahead of schedule. Net cash used in financing activities in fiscal year 2008 related mainly to the repayment of the revolving credit facility of
the Company.

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

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 the U.S. Dollar-denominated exclusivity payment and borrowings
where the functional currency is the Euro, and the Exchange. Sironas management believes that these items are either nonrecurring or non-cash in nature, and should be considered by investors in assessing Sironas financial condition,
operating performance and underlying strength.

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.

Long-term debt

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

##### Table of Contents

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 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 and are
amortized using the effective interest method over the term of the loan.

The amounts disclosed above include interest of $0.3 million on long-term debt accreted at September 30,
2010; future variable interest payments are not included.

Off-Balance Sheet Arrangements

In July 2005, Sirona entered into a sale and leaseback agreement regarding unused land on the Bensheim site of Sirona in Germany. The land
was sold for Euro 0.9 million ($1.2 million at the U.S. Dollar/Euro exchange rate of September 30, 2010) to an unrelated property development company, who constructed an office building based on Sironas specifications on the site.
Sirona leases the building from the property development company through an 20-year lease. Rental payments started in April 2007 when the building was ready for occupancy. Under the terms of the lease, rent is fixed at Euro 1.2 million ($1.6
million at the U.S. Dollar/Euro exchange rate of September 30, 2010) per annum until 2013. After 2013, rent is subject to adjustment according to an inflation index. The land remains an asset on Sironas balance sheet and the building
has been accounted for as an operating lease.

Sirona does not have other off-balance sheet financing arrangements other than
its derivatives.

Critical Accounting Policies

The preparation of financial statements in conformity with U.S. GAAP requires Sirona to make estimates and assumptions that affect amounts reported in its consolidated financial statements and
accompanying notes. These estimates and assumptions are evaluated on an ongoing basis based on historical developments, market conditions, industry trends and other information Sirona believes to be reasonable under the circumstances. There can be
no assurance that actual results will conform to Sironas estimates and assumptions, and that reported results of operations will not be materially adversely affected by the need to make accounting adjustments to reflect changes in its
estimates and assumptions from time to time. The following accounting policies are those that Sirona believes to be the most sensitive to its estimates and assumptions.

##### Table of Contents

Revenue Recognition

Revenue, net of related discounts and allowances, is recognized when persuasive evidence of the arrangement exists, the price is fixed or determinable, collectability is reasonably assured and title and
risk of loss has passed to customers based on the shipping terms. Returns of products, excluding warranty related returns, are infrequent and insignificant. Revenue related to products that contain software that is more than incidental to the
product is recognized in accordance with ASC 985-605, Software  Revenue Recognition. For orders which contain one or more elements to be delivered at a future date, but do not include software that is more than incidental to the other
elements, the Company recognizes revenue in accordance with ASC 605-25, Revenue Recognition  Multiple-Element Arrangements. For revenue on certain CEREC units recognized in accordance with both ASC 985-605 and ASC 605-25, the Company
allocates revenues between the various elements using the relative fair value method because vendor-specific objective evidence of fair value (VSOE) exists for all elements. Under the relative fair value method, as applied by the
Company, the revenue is allocated between the elements of the arrangement in proportion to the VSOE of each element. The revenue allocated to the service contract is deferred until the service is provided. For revenue on certain GALILEOS units
recognized in accordance with both ASC 985-605 and ASC 605-25, the Company allocates revenues between the various elements using the residual method because VSOE exists for the undelivered service contract but does not exist for the delivered
product. Under the residual method, as applied by the Company, the revenue is allocated first to the undelivered elements based on VSOE and the residual contract amount is then allocated to the delivered element. The revenue allocated to the service
contract is deferred until the service is provided.

The revenue allocated to the CEREC or GALILEOS product sold, which
contains software and hardware the functionality of which is dependent on the software and for which the software is integral (i.e., software-related hardware), is recognized as revenue upon delivery which is when the risk and rewards of ownership
are transferred. The VSOE of products and service contracts is based on the price charged when the same element is sold separately to customers or, in the case of GALILEOS service contracts that are sold together with the GALILEOS product, based on
the service contract renewal rate.

The Company offers its customers an option to purchase extended warranties on certain
products. The Company recognizes revenue on these extended warranty contracts ratably over the life of the contract. The costs associated with these extended warranty contracts are recognized when incurred.

The Company offers discounts to its distributors if certain conditions are met. Discounts and allowances are primarily based on the
volume of products purchased or targeted to be purchased by the individual customer or distributor, but may also be involved in trade-in programs. Discounts are deducted from revenue at the time of sale or when the discount is granted, whichever is
later. The Company estimates volume discounts based on the individual customers historical and estimated future product purchases.

Amounts received from customers in advance of product shipment are classified as deferred income until the revenue can be recognized in accordance with the Companys revenue recognition policy.

Pensions and 401(k) Plan

The Company has defined benefit and defined contribution pension plans and an early retirement plan.

As of September 30, 2007, the Company adopted the recognition provisions of ASC 715-30, Compensation-Retirement Benefits  Defined Benefit Plans-Pension. Upon adoption, Sirona recognized as an
adjustment to accumulated other comprehensive income the funded status of its benefit plans, measured as the difference between the fair value of plan assets and benefit obligations as of September 30, 2007, net of related tax effects.
Beginning in fiscal year 2008, Sirona recognizes changes in the funded status of its benefit plans, not yet recognized in the income statement, in other comprehensive income until they are amortized as a component of net periodic benefit cost.

Pension expense is recognized on an accrual basis over the employees approximate service periods. Defined benefit
pension costs are determined by using an actuarial method, which provides for the deferral of actuarial gains and losses (in excess of a specified corridor) that result from changes in assumptions or actual experience differing from that assumed.
Costs relating to changes in the benefit plan as well as the transition obligation are amortized. Disclosure of the components of periodic pension cost is also required. When purchase accounting is applied, pension liabilities are recognized for the
projected benefit obligation in excess of plan assets.

##### Table of Contents

The key assumption used in the actuarial calculations for the defined benefit pension plans
is the selection of the appropriate discount rate. The discount rate has been selected by reference to market interest rates. The discount rate used reflects the rates available on high quality fixed income investment of appropriate duration at the
measurement dates of each year. Fluctuations in market interest rates could impact the amount of pension expense recorded for these plans. The discount rate assumption changed from 5.50% at September 30, 2009 to 4.75% at September 30,
2010, thereby affecting the amount of pension obligation recorded at September 30, 2010.

Plan assets consist of
insurance policies with a guaranteed minimum return by the insurance company and an excess profit participation feature for a portion of the benefits. Sirona pays the premiums on the insurance policies but does not manage the investment of the
funds; the insurance company makes all decisions on investment of funds, including the allocation to asset groups. The fair value of the plan assets such as equity securities, fixed-income investments, and others is based on the cash surrender
values reported by the insurance company.

Contributions made to the defined contribution pension plans and the 401(k) savings
plan for U.S. employees are accrued based on the contributions required by the plan.

The Company also has an early retirement
plan, Altersteilzeit (ATZ), which allows certain German employees who have been accepted into the plan to retire at 60 rather than at the legal retirement age of 67. Eligible employees are those who have attained the age of 55 by
calendar year 2009 and have been accepted to participate in the ATZ plan. The ATZ plan can cover a period between the ages of 58 to 63 of the participating employees and is split into an active service period, where the employees work full time for
the Company, and an inactive service period, where the employees do not work for the Company. During the active service period, the employees receive 50% of their salary and the remaining 50% of their salary, plus a bonus payment equal to 35% of
their salary is paid during the inactive service period. The Company recognizes the salary component of the ATZ plan over the period from the beginning of the ATZ period to the end of the active service period. The Company recognizes the bonus
component over the period from the point at which the employee signs the ATZ contract until the end of the active service period.

Income Taxes

Sirona recognizes deferred tax assets and liabilities based on the differences between the financial statement carrying amounts and the
tax basis of assets and liabilities. Sirona regularly reviews its deferred tax assets for recoverability and establishes a valuation allowance, as necessary, based on historical taxable income, projected future taxable income, the expected timing of
the reversals of existing temporary differences and the implementation of tax-planning strategies. If Sirona is unable to generate sufficient future taxable income in certain tax jurisdictions, or if there is a material change in the actual
effective tax rates or time period within which the underlying temporary differences become taxable or deductible, it could be required to increase its valuation allowance against its deferred tax assets resulting in an increase in its effective tax
rate and an adverse impact on operating results. As of September 30, 2010, Sirona had recorded valuation allowances against its deferred tax assets in the amount of $2.2 million. Further information on income taxes is provided in Note 10 to the
consolidated financial statements appearing elsewhere in this report.

Effective at the beginning of fiscal year 2008, the
Company adopted the provisions of ASC 740, Income Taxes. Further information may be found in Note 10, Income Taxes in the Notes to Consolidated Financial Statements of this Form 10-K.

Management believes it is more likely than not that forecasted income, including income that may be generated as a result of certain tax
planning strategies, together with the tax effects of the deferred tax liabilities, will be sufficient to fully recover the remaining deferred tax assets. In the event that the Company determines all or part of the net deferred tax assets are not
realizable in the future, the Company will make an adjustment to the valuation allowance that would be charged to earnings in the period such determination is made. In addition, the calculation of tax liabilities involves significant judgment in
estimating the impact of uncertainties in the application of ASC 740 and other complex tax laws. Resolution of these uncertainties in a manner inconsistent with managements expectations could have a material impact on the Companys
financial condition and operating results.

Impairment of Long-Lived and Finite-Lived Assets

Sirona assesses all its long-lived assets for impairment whenever events or circumstances indicate their carrying value may not be
recoverable. Sironas management assesses whether there has been an impairment by comparing anticipated undiscounted future cash flows from operating activities with the carrying value of the asset. The factors considered by



42



---

##### Table of Contents

Sironas management in this assessment include operating results, trends and prospects, as well as the effects of obsolescence, demand, competition and other economic factors. If an
impairment is deemed to exist, management records an impairment charge equal to the excess of the carrying value over the fair value of the impaired assets. This could result in a material charge to earnings.

Impairment of Indefinite-Lived Assets

Sirona tests goodwill for impairment annually on September 30 by comparing the fair value of its reporting units to their carrying values. We regard our reporting units to be our operating segments
(Dental CAD/CAM Systems, Imaging Systems, Treatment Centers, and Instruments). Goodwill has been allocated to reporting units for impairment testing. Goodwill may be tested for impairment between annual tests if an event occurs or circumstances
change that would more likely than not reduce the fair value of a reporting unit below its carrying value. These events or circumstances could include a significant change in the business climate, legal factors, operating performance indicators,
competition, sale or disposition of a significant portion of the business or other factors. If the carrying amount of a reporting unit exceeds its fair value, additional steps, including an allocation of the estimated fair value to the assets and
liabilities of the reporting unit, would be necessary to determine the amount, if any, of goodwill impairment. In this second step, a fair value exercise similar to a business combination would be performed where the individual identifiable assets
and liabilities of the reporting unit are valued at fair value with the difference between the fair value of the reporting unit being the implied fair value of goodwill. The Company uses a discounted future cash flow model to estimate reporting unit
fair value. Significant assumptions in our discounted cash flow model include discount rate, revenue and profit margin growth and terminal growth rates. Although we believe our judgments, estimates and assumptions used in determining fair value are
reasonable, making material changes to such judgments, estimates and/or assumptions could materially affect such impairment analyses and our financial results.

Sirona evaluates trademarks, which are considered indefinite-lived intangible assets, for impairment at least annually or whenever events or circumstances indicate their carrying value might be impaired.
In performing this assessment, Sironas management considers operating results, trends and prospects, as well as the effects of obsolescence, demand, competition and other economic factors. The carrying value of trademarks is considered
impaired when their carrying value exceeds their fair market value. In such an event, an impairment loss is recognized equal to the amount of that excess. Key assumptions in determining fair value include using the projected cash flows discounted at
a rate commensurate with the risk involved.

|ITEM 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

Sironas primary market risk exposure is interest rate risk associated with short and long-term bank loans bearing variable interest rates. To manage this interest rate risk exposure, Sirona entered
into interest rate swap agreements, all of which expired on March 31, 2010 and were not renewed. Sirona is also exposed to foreign currency risk, which can adversely affect our sales and operating profits. To manage this risk, Sirona enters
into forward exchange contracts.

The following discussion should be read in conjunction with Notes 2 and 13 to Sironas
audited consolidated financial statements appearing elsewhere in this report, which provide further information on Sironas derivative instruments.

Interest Rate Sensitivity

To reduce the exposure associated with
Sironas variable rate debt, Sirona entered into interest rate swap agreements in 2006 that limit the variable rate for a substantial portion of the debt terms (i.e. through March 2010). These interest rate swap agreements expired on
March 31, 2010 and were not renewed. See Managements Discussion and Analysis of Financial Conditions and Results of Operations - Long-term debt for further details.

A hypothetical, instantaneous increase of one percentage point in the interest rates applicable to the variable interest rate debt would
have increased the interest expense for the fiscal year ended September 30, 2010, by approximately $2.5 million.

As of
September 30, 2009, the interest rate swaps had notional amounts of $363.0 million and a negative fair value of $(6.5) million. The variable benchmark interest rates associated with these instruments ranged from 3.5% to 5.24%. A
hypothetical, instantaneous increase of one percentage point in the interest rates applicable to the variable interest rate debt would have increased the interest expense for the fiscal year ended September 30, 2009, by approximately $1.5
million.

Exchange Rate Sensitivity

The Euro is the functional currency for the majority of Sironas subsidiaries, including its German operations, which are the primary sales and manufacturing operations of Sirona. Sales from other
Sirona operations are denominated in various foreign currencies. Sales in Euro, U.S. Dollar and other currencies represented 44.7%, 37.2% and 18.1%, respectively, of total sales for fiscal year 2010. In order to hedge portions of the
transactional exposure to fluctuations in exchange rates between the U.S. Dollar and the Euro, based on forecasted and firmly committed cash flows, Sirona enters into forward foreign currency (different from functional currency) contracts.
These forward foreign currency contracts are intended to protect Sirona against the short-term effects of changes in the exchange rates. Sirona does not apply hedge accounting to these forward foreign currency contracts.

##### Table of Contents

The table below provides information, as of September 30, 2010, about receivables and
derivative financial instruments by functional currency and presents such information in U.S. Dollars, which is Sironas reporting currency. The table summarizes information on instruments and transactions that are sensitive to foreign currency
exchange rates. The estimated fair value of receivables is considered to approximate their carrying value because receivables have a short maturity. For foreign currency forward exchange agreements, the table presents the notional amounts and
weighted average exchange rates by expected (contractual) maturity dates. These notional amounts generally are used to calculate the contractual payments to be exchanged under the contract.

|-------- | -----------------------

Evaluation of
Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer (principal
executive officer) and chief financial officer (principal financial officer), evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934), as of
September 30, 2010. Based upon this evaluation, our chief executive officer and chief financial officer concluded that, as of September 30, 2010, the Companys disclosure controls and procedures are effective. Our disclosure controls
and procedures are designed to ensure that information relating to the Company, including our consolidated subsidiaries, that is required to be disclosed in the reports we file or submit under the Securities Exchange Act of 1934 is recorded,
processed, summarized and reported within the time periods specified in Commissions rules and forms, and is accumulated and communicated to our management, including our principal executive officer and our principal financial officer, as
appropriate to allow timely decisions regarding required disclosure.

Managements Annual Report on Internal Control over Financial
Reporting

Our management is responsible for establishing and maintaining adequate internal control over the Companys
financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of the Companys internal control over financial reporting as of September 30, 2010.
In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control Integrated Framework. Based on our assessment, management believes that, as of
September 30, 2010, our internal control over financial reporting is effective based on those criteria.

The independent
registered public accounting firm, which audited the Companys financial statements included in this Form 10-K, has issued an attestation report on the Companys internal control over financial reporting. Please see attestation report
on page F-3.

Changes in Internal Control over Financial Reporting

No change in our internal control over financial reporting (as defined in rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred
during the quarter ended September 30, 2010, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Supplement
Agreement to Service Agreement with Jost Fischer

On November 15, 2010, the Companys executive compensation
committee of the board of directors approved a supplement agreement to the service agreement between the Company, Sirona Dental GmbH, and Jost Fischer, the Companys Chairman and Chief Executive Officer. The supplement agreement amends the
executive service agreement between Sirona Dental GmbH and Mr. Fischer, dated as of October 10, 2007, as amended by the amended and restated service agreement between the Company, Sirona Dental GmbH and Jost Fischer, dated as of December 2,
2008.

The supplement agreement provides that Mr. Fischer may provide services under the service agreement partially to the
Company, and that Mr. Fischers yearly salary and bonus under the service agreement will be paid by the Company pro rata to the days he has worked for the Company compared to total days to be worked under the service agreement, with the
remaining portion of the yearly salary and bonus to be paid by Sirona Dental GmbH. In order to facilitate the payment mechanism, the Company will pay Mr. Fischer a fixed amount on a monthly basis in the amount of 20% of the total salary, with the
remaining 80% to be paid by Sirona Dental GmbH. Within 30 days following the end of the calendar year, the Company and Sirona Dental GmbH will each compensate the other for the difference between the portion of salary actually paid and the pro rata
portion to be paid for such calendar year.

The supplement agreement further provides that Mr. Fischer will be subject to tax
equalization, by which he will remain neutral, subject to certain conditions and limitation, from a tax perspective with respect to (i) compensation received by him from the Company and/or Sirona Dental GmbH, including any U.S. tax on salary,
bonuses, share based compensation (including effects in case of exercises), and (ii) the indirect investment of Mr. Fischer in the Company. Mr. Fischer will pay the same amount of income taxes as he would have paid had he performed all of his duties
in Austria and did not perform the duties in the United States of America and been subject to a salary split mentioned above.

Supplement
Agreement to Service Agreement with Simone Blank

On November 15, 2010, the Companys executive compensation
committee of the board of directors approved a supplement agreement to the service agreement between the Company, Sirona Dental GmbH, and Simone Blank, the Companys Executive Vice President and Chief Financial Officer. The supplement agreement
amends the executive service agreement between Sirona Dental GmbH and Ms. Blank, dated as of October 10, 2007, as amended by the amended and restated service agreement between the Company, Sirona Dental GmbH and Simone Blank, dated as of December 2,
2008.

The supplement agreement provides that Ms. Blank may provide services under the service agreement partially to the
Company, and that Ms. Blanks yearly salary and bonus under the service agreement will be paid by the Company pro rata to the days she has worked for the Company compared to total days to be worked under the service agreement, with the
remaining portion of the yearly salary and bonus to be paid by Sirona Dental GmbH. In order to facilitate the payment mechanism, the Company will pay Ms. Blank a fixed amount on a monthly basis in the amount of 20% of the total salary, with the
remaining 80% to be paid by Sirona Dental GmbH. Within 30 days following the end of the calendar year, the Company and Sirona Dental GmbH will each compensate the other for the difference between the portion of salary actually paid and the pro rata
portion to be paid for such calendar year.

The supplement agreement further provides that Ms. Blank will be subject to tax equalization, by
which she will remain neutral, subject to certain conditions and limitation, from a tax perspective with respect to (i) compensation received by her from the Company and/or Sirona Dental GmbH, including any U.S. tax on salary, bonuses, share based

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors

Sirona
Dental Systems, Inc.:

We have audited the accompanying consolidated balance sheets of Sirona Dental Systems, Inc.
and subsidiaries as of September 30, 2010 and 2009, and the related consolidated statements of income, shareholders equity and comprehensive income, and cash flows for each of the years in the three-year period ended September 30,
2010. These consolidated financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those
standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Sirona Dental Systems, Inc. and subsidiaries as of September 30, 2010 and 2009, and the results of their operations and their cash flows for each of the years in the three-year
period ended September 30, 2010 in conformity with generally accepted accounting principles.

We also have audited, in
accordance with the standards of the Public Company Accounting Oversight Board (United States), Sirona Dental Systems, Inc.s internal control over financial reporting as of September 30, 2010, based on criteria established in
Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated November 18, 2010 expressed an unqualified opinion on the effectiveness of Sirona Dental
Systems, Inc.s internal control over financial reporting.

We have audited Sirona Dental Systems, Inc.s internal control over financial reporting as of
September 30, 2010, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Sirona Dental Systems, Inc.s management is
responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Managements Report on Internal Control over
Financial Reporting under Item 9A. Our responsibility is to express an opinion on the Companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material
weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe
that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a
process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys
internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the
company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company
are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the
companys assets that could have a material effect on the financial statements.

Because of its inherent limitations,
internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions,
or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Sirona Dental
Systems, Inc. maintained, in all material respects, effective internal control over financial reporting as of September 30, 2010, based on criteria established in Internal ControlIntegrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated
balance sheets of Sirona Dental Systems, Inc. and subsidiaries as of September 30, 2010 and 2009, and the related consolidated statements of income, shareholders equity and comprehensive income, and cash flows for each of the years
in the three-year period ended September 30, 2010, and our report dated November 18, 2010 expressed an unqualified opinion on those financial statements.

SIRONA DENTAL SYSTEMS, INC. AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1. The Company and its operations

Sirona Dental Systems, Inc.
(Sirona, Company, we, us, or our) and its subsidiaries manufacture high quality, technologically advanced dental technology and systems solutions for the global dental market. We offer a
broad range of products across all major segments of the dental technology market including CEREC, CAD/CAM systems, digital and film based intra oral and 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 strengthened 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 the primary facility located in Bensheim, Germany, as well as other support, manufacturing, assembling,
and sales and service facilities located elsewhere throughout the world.

2. Basis of presentation and summary of significant accounting
policies

The accompanying financial statements have been prepared in accordance with accounting principles generally
accepted in the United States (U.S. GAAP). 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.

In the year ended September 30, 2010, the Company adopted the new accounting guidance for reporting a noncontrolling interest (NCI) in a subsidiary according to FASB Codification ASC 810,
Consolidation. 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 Consolidated Balance Sheet. Additionally, the Company reported the portion of net
income attributed to the Company and NCI separately in the Consolidated Income Statements. The portion of comprehensive income attributed to the Company and NCI are reported separately in the Statement of Changes in Shareholders Equity. 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.

Use of estimates

The
preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities
at the date of the consolidated financial statements and the reported amount of revenues and expenses during the reporting periods. Actual results could differ from estimates. Some of the more significant estimates include allowances for doubtful
accounts, inventory valuation reserves, purchase accounting assumptions, depreciable lives of assets, amortization periods, impairment of long-lived assets, deferred tax asset valuation allowance, discounts to customers, pension reserves, provisions
and warranty reserves.

SIRONA DENTAL SYSTEMS, INC. AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Foreign currency

The functional currency for foreign operations has been determined in all cases to be the local currency. Assets and liabilities of foreign subsidiaries are translated at exchange rates on the balance
sheet date; revenue and expenses are translated at the weighted average exchange rates for the interim periods within the full period. Operating cash flows are translated based on the weighted average exchange rates for the full period based on the
net income line. Investing and financing cash flows are translated based on the exchange rate applicable to the respective transaction. The effects of these translation adjustments are recognized in shareholders equity, as a component of
accumulated other comprehensive income. Exchange gains and losses arising from transactions denominated in a currency other than the functional currency of the entity involved, as well as the fair value adjustment of forward foreign exchange
contracts, are shown separately on the face of the consolidated statements of income.

Comprehensive income

In addition to net income, comprehensive income includes other charges or credits to equity other than those resulting from transactions
with shareholders. Accumulated other comprehensive income relates to foreign currency translation adjustments related to the Companys foreign subsidiaries as well as to the pension adjustment resulting from the application of ASC 715-30,
Compensation-Retirement Benefits  Defined Benefit Plans-Pension. Components of comprehensive income are included within the Consolidated Statements of Shareholders Equity and Comprehensive Income.

Revenue recognition

Revenue, net of related discounts and allowances, is recognized when persuasive evidence of the arrangement exists, the price is fixed or
determinable, collectability is reasonably assured and title and risk of loss has passed to customers based on the shipping terms. Returns of products, excluding warranty related returns, are infrequent and insignificant. Revenue related to products
that contain software that is more than incidental to the product is recognized in accordance with the provisions of ASC 985-605, Software  Revenue Recognition. For orders which contain one or more elements to be delivered at a future
date, but do not include software that is more than incidental to the other elements, the Company recognizes revenue in accordance with ASC 605-25, Revenue Recognition  Multiple-Element Arrangements. For revenue on certain CEREC units
recognized in accordance with both ASC 985-605 and ASC 605-25, the Company allocates revenues between the various elements using the relative fair value method because vendor-specific objective evidence of fair value (VSOE) exists for
all elements. Under the relative fair value method, as applied by the Company, the revenue is allocated between the elements of the arrangement in proportion to the VSOE of each element. The revenue allocated to the service contract is deferred
until the service is provided. For revenue on certain GALILEOS units recognized in accordance with both ASC 985-605 and ASC 605-25, the Company allocates revenues between the various elements using the residual method because VSOE exists for the
undelivered service contract but does not exist for the delivered product. Under the residual method, as applied by the Company, the revenue is allocated first to the undelivered elements based on VSOE and the residual contract amount is then
allocated to the delivered element. The revenue allocated to the service contract is deferred until the service is provided.

The revenue allocated to the CEREC or GALILEOS product sold, which contains software and hardware the functionality of which is dependent
on the software and for which the software is integral (i.e., software-related hardware), is recognized as revenue upon delivery which is when the risk and rewards of ownership are transferred. The VSOE of products and service contracts is based on
the price charged when the same element is sold separately to customers or, in the case of GALILEOS service contracts that are sold together with the GALILEOS product, based on the service contract renewal rate.

The Company offers its customers an option to purchase extended warranties on certain products. The Company recognizes revenue on these
extended warranty contracts ratably over the life of the contract. The costs associated with these extended warranty contracts are recognized when incurred.

The Company offers discounts to its distributors if certain conditions are met. Discounts and allowances are primarily based on the volume of products purchased or targeted to be purchased by the
individual customer or distributor. Discounts are deducted from revenue at the time of sale or when the discount is offered, whichever is later. The Company estimates volume discounts based on the individual customers historical and estimated
future product purchases.

Amounts received from customers in advance of product shipment or rendering of services are
classified as deferred income until the revenue can be recognized in accordance with the Companys revenue recognition policy.

Research and development

Amounts spent by the Company for research and development (R&D) efforts are recorded as R&D expenses when incurred. R&D costs relate primarily to internal costs for salaries, direct overhead
costs and outside vendors. The Company capitalizes costs of equipment used for general R&D if it has alternative future use. The depreciation related to this capitalized equipment is included in the Companys R&D costs. Software
development costs incurred prior to the attainment of technological feasibility are considered R&D and are expensed as incurred.

Warranty expense

The
Company offers warranties on its products for periods between one and three years. Estimated future warranty obligations related to product sales are charged to operations in the period in which the related revenue is recognized. These estimates are
based on historical warranty experience and other relevant information of which the Company is aware. Estimated warranty expenses are recorded as an accrued liability and selling, general and administrative expense. During the fiscal years ended
September 30, 2010, 2009 and 2008, warranty expense was $18,903, $20,512 and $23,217, respectively.

Shipping and handling costs

Shipping and handling costs charged to customers are included in revenues and the associated expense is recorded in cost
of sales for all periods presented.

Advertising costs

Advertising costs are expensed as incurred and recorded within selling, general and administrative expense. During the fiscal years ended September 30, 2010, 2009 and 2008, advertising expense was
$22,769, $25,804 and $27,884 respectively.

Pension benefits

The Company has defined benefit and defined contribution pension plans and an early retirement plan. Sirona recognizes changes in the funded status of its benefit plans, not yet recognized in the income
statement, in other comprehensive income until they are amortized as a component of net periodic benefit cost in accordance with the provisions of ASC 715-30, Compensation-Retirement Benefits  Defined Benefit Plans-Pension.

Pension expense is recognized on an accrual basis over the employees approximate service periods. Defined benefit pension costs are
determined by using an actuarial method, which provides for the deferral of actuarial gains and losses (in excess of a specified corridor) that result from changes in assumptions or actual experience differing from that assumed. Costs relating to
changes in the benefit plan as well as the transition obligation are amortized. Disclosure of the components of periodic pension cost is also required. When purchase accounting is applied, pension liabilities are recognized for the projected benefit
obligation in excess of plan assets.

For the defined contribution pension plans, the net pension cost is equal to the
contributions required by the plan.

The Company also has an early retirement plan, Altersteilzeit (ATZ), which
allows certain German employees who have been accepted into the plan to retire at 60 rather than at the legal retirement age of 67. Eligible employees are those who have attained the age of 55 by calendar year 2009 and have been accepted to
participate in the ATZ plan. The ATZ plan can cover a period between the ages of 58 to 63 of the participating employees and is split into an active service period, where the employees work full time for the Company, and an inactive service period,
where the employees do not work for the Company. During the active service period, the employees receive 50% of their salary and the remaining 50% of their salary, plus a bonus payment equal to 35% of their salary is paid during the inactive service
period. The Company recognizes the salary component of the ATZ plan over the period from the beginning of the ATZ period to the end of the active service period. The Company recognizes the bonus component over the period from the point at which the
employee signs the ATZ contract until the end of the active service period.

Income Taxes

Differences between the basis of assets and liabilities for financial statement purposes and for tax return purposes are recorded as deferred tax assets or deferred tax liabilities in the accompanying
consolidated financial statements. Deferred taxes represent the tax consequences in future years of these differences at each balance sheet date, based on the enacted tax laws and statutory rates applicable to the periods in which the differences
are expected to affect taxable income. The provision (benefit) for income taxes represents the tax payable for the period and the change during the period in deferred tax assets and liabilities. A valuation allowance is established when it is more
likely than not that the deferred tax assets are not realizable. The effect on deferred tax assets and liabilities of a change in the tax rates is recognized in income as an adjustment to income tax expense in the period that includes the enactment
date. See Note 10, Income Taxes for additional information.

Cash and cash equivalents

All highly liquid investments with an original maturity of three months or less are considered to be cash equivalents. Investments in
money market funds are carried at fair value. All other cash equivalents are stated at cost, which approximates fair value.

Restricted
cash

Restricted cash represents cash balances pledged as collateral to financial institutions that provide security for
prepayments from customers and other bonds.

Accounts receivable

Accounts receivable are stated at the invoiced amount, less allowances for doubtful accounts, which approximates fair value given their
short-term due dates. Collectability of accounts receivable is regularly reviewed and is based upon managements knowledge of customers and compliance with credit terms. The allowance for doubtful accounts is adjusted based on such evaluation,
with a corresponding provision included in selling, general and administrative expense. Accounts receivable balances are written off when management deems the balances uncollectible.

Inventory

Inventory is carried at the lower of cost or market value. Cost
is determined using standard costing, which approximates the weighted average cost method. In addition to direct material and direct labor costs, certain costs related to the overhead and production expenses are included in inventory. Inventory
reserves are provided for risks relating to slow moving, unmarketable and obsolete items.

Investments in companies

Investments in associated companies over which the Company can exercise significant influence but not effective control are accounted for
using the equity method. Investments in associated companies over which the Company cannot exercise significant influence or effective control are accounted for at cost.

Property, plant and equipment

Property, plant and equipment are recorded at historical cost plus the fair value of asset retirement costs, if any and if reasonably
estimable, less accumulated depreciation. Additions, improvements and major renewals, which extend the useful life of the asset, are capitalized; maintenance and repairs are expensed as incurred. When assets are retired or disposed of, the assets
and related accumulated depreciation and amortization are removed from the balance sheet and the resulting gain or loss is reflected in current operating income. Development costs for external use software incurred after the establishment of
technological feasibility are capitalized and amortized to cost of revenues on a straight-line basis over the expected useful life of the software. Costs of software developed for internal use incurred during the development of the application are
capitalized and amortized to operating expense on a straight-line basis over the expected useful life of the software. Prepayments for property, plant & equipment are classified as property, plant and equipment and are not depreciated until
the assets are received and placed into service.

The cost of plant and equipment is depreciated using the straight-line
method over the following estimated useful lives of the respective assets.



|                                                 |  |  |                | 
|------------------------------------------------ |  |  | -------------- | 
|Buildings                                        |  |  | 25 to 50 years | 
|Building improvements and leasehold improvements |  |  | 5 to 10 years  | 
|Machinery and technical equipment                |  |  | 3 to 10 years  | 
|Software and software licenses                   |  |  | 3 to 5 years   | 

Finite-lived intangible assets

Finite-lived intangible assets are amortized according to the pattern in which the economic benefit of the asset is used
up over their estimated useful lives, as shown below.



|                                      |  |  |                | 
|------------------------------------- |  |  | -------------- | 
|Patents and licenses                  |  |  | 10 to 13 years | 
|Technologies and Dealer Relationships |  |  | 1 to 13 years  | 

For intangible assets
acquired after October 1, 2009, the Company adopted the new accounting guidance for determination of the useful lives of intangible assets in 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 an impact on the Companys consolidated financial statements.

Impairment of long-lived and finite-lived assets

Long lived assets held for use by the Company are reviewed for impairment whenever events or circumstances provide evidence that suggests the carrying amount of the asset may not be recoverable. The
Company performs ongoing impairment analysis on technology-related intangible assets. Determination of whether an impairment exists is based upon a comparison of the identifiable undiscounted cash flows of the assets or groups of assets to the
carrying amount of the assets or groups of assets. If impaired, the resulting charge reflects the excess of the assets carrying amount over its fair value.

Goodwill and indefinite-lived intangible assets

Goodwill and indefinite
lived intangible assets, consisting of certain trademarks, are not amortized, but are tested for impairment on an annual basis as of September 30, or whenever events or circumstances indicate that the carrying amount may not be recoverable.
These impairment tests are based upon a comparison of the fair value of the reporting units to their respective carrying amount. If the carrying amount of the reporting unit exceeds its fair value, the goodwill impairment loss is measured as the
excess of the carrying amount of goodwill over its implied fair value. If impairment is identified on indefinite-lived intangibles, the resulting charge reflects the excess of the assets carrying amount over its fair value.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)



On October 1, 2009, the Company adopted the new accounting guidance for business
combinations according to 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 an impact on the Companys consolidated financial statements.

Other non-current assets

Other non-current assets and prepaid expenses are mainly comprised of capitalized debt issuance costs. The costs are amortized using the
effective interest method. The non-current unamortized balance of such debt issuance costs was $130 and $1,054 as of September 30, 2010 and 2009, respectively.

Derivative financial instruments

The Company enters into forward foreign
currency contracts in order to manage currency risks arising from its forecasted and firmly committed foreign currency denominated cash flows. The Company enters into these contracts to limit the foreign exchange rate risk for periods generally not
to exceed six months. The Company also enters into interest rate swaps to manage its interest rates on its long term debt.

The Company does not utilize financial instruments for speculative purposes. The Company accounts for derivative financial instruments in
accordance with ASC 815, Derivatives and Hedging. This Topic prescribes requirements for designation and documentation of hedging relationships and ongoing assessments of effectiveness in order to qualify for hedge accounting. The Company has
not designated any of its derivatives as qualifying for hedge accounting under ASC 815. All derivatives instruments are therefore recognized as either assets or liabilities in the consolidated balance sheet at fair value. The fair value of the
forward foreign currency contracts and interest rate swaps are included within prepaid and other current assets or current accrued liabilities, depending on whether they are an asset or a liability, and the change in fair value is recognized within
Gains (losses) on derivative instruments in the consolidated statement of income.

Fair value of financial instruments

Financial instruments consist of cash, cash equivalents, accounts receivable, accounts payable, foreign currency forward
contracts and interest rate swaps. The fair values 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 the foreign currency
forward contracts and interest rate swaps are estimated based on information such as quotes from financial institutions.

At
September 30, 2010, the foreign exchange forward contracts outstanding had notional amounts of $49,332 ($58,326 as at September 30, 2009) and a fair value asset of $1,452 (fair value asset of $1,355 as at September 30, 2009), with the
unrealized fair value loss for the fiscal year ended September 30, 2010 of $(262) (year ended September 30, 2009, gain of $3,699).

During the fiscal year ended September 30, 2010, the interest rate swaps expired on March 31, 2010 and were not renewed. At September 30, 2009, the interest rate swaps had notional amounts
of $363,008 and a fair value liability of $(6,500), with the unrealized fair value loss for the fiscal year ended September 30, 2009, of $(3,850).

Concentration of credit risk

Financial instruments that potentially subject the Company to concentrations of credit risk include cash, cash equivalents and accounts
receivable. Sirona has two customers accounting for more than 45% of revenue for the fiscal years ended September 30, 2010 and 2009. The accounts receivables from these two customers totaled $23,841 and $32,703 as of September 30, 2010 and
2009, respectively.

3. Recent Accounting Pronouncements

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.

4. Employee Share-Based Compensation

ASC 718, Compensation  Stock Compensation, requires that all share based compensation arrangements, including
grants of stock option awards to employees, be recognized based on the estimated fair value of the share-based payment award.

Share-based awards outstanding under Schicks legacy stock option plans continue to be outstanding. At the date of the acquisition
of Schick, 862,220 vested and 458,179 unvested options were outstanding. Options granted under these plans have 10 year contractual lives and vesting periods of between 2 to 4 years from the grant date. The Company does not expect to repurchase
these shares within the next 12 months.

In contemplation of the acquisition by Sirona, Schick conditionally granted employees
and consultants 1,530,000 options upon the acquisition by Sirona. The four year vesting period of that grant commenced with the closing of the business acquisition on June 20, 2006.

All Schick legacy plans have expired, and accordingly, no further options may be granted under such plans.

On December 8, 2009 and May 10, 2010, the Company granted 188,000 and 25,000 RSUs under the Equity Incentive Plan (the
2006 Plan), respectively. The RSUs vest over a period of four years (one third each at December 8, 2011, 2012 and 2013 for the December grant) and ratably over three years for the May grant. All grants expire ten years after
the date of the grant. The RSUs do not have rights to dividends prior to vesting. The value of each RSU is determined by the closing price as of the date of grant of $34.45 for the December 2009 grant and $38.11 for the May 2010 grant. 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 September 30, 2010, 1,634,920 shares were available for future grant under the 2006 Plan.

In fiscal year 2009, the Company granted 1,247,700 stock options under the 2006 Plan. Grants generally vest over four years. All grants expire ten years after the date of the grant. The 2006 Plan, as
amended in February 2009, provides for grants of up to 4,550,000 options and or restricted shares to employees, directors and consultants.

The fair value of options granted in 2009 under the 2006 Plan were estimated using the Black-Scholes option pricing model using assumptions in the following table. The exercise price is equal to fair
market value at the grant date. Expected volatility is based on the Companys history stock price volatility. The risk-free rate is based on the U.S. Treasury yield curve in effect at the day of grant and has a term equal to the expected life
of the option. The expected life represents the period of time the options are expected to be outstanding based on anticipated grantee behavior. The expected dividend yield is based on the Companys history of not paying regular dividends in
the past and the Companys current intention not to pay dividends in the foreseeable future.

In January and March 2009, the Company completed two value-for-value stock option exchanges for holders of eligible options granted under
the 1996 Plan and the 2006 Plan with exercise prices of $21.32 or higher. The Companys independent directors did not participate in the exchange programs. Under value-for-value option exchange programs, the option holders surrendered their
eligible options in exchange for a lower number of replacement options and agreed to an additional year of service for vesting and having an exercise price equal to the closing price of Sironas stock on January 21, 2009 or March 30,
2009, the date the respective offers expired. The fair value of the replacement options approximates the fair value of the surrendered options in the aggregate, as determined using the Black-Scholes option pricing model as of the respective exchange
date. Aggregate future non-cash stock option compensation expense is unchanged by the exchange programs in terms of both amount and timing of recognition.

Under the January 21, 2009 option exchange program, holders of 1,000,500 eligible options issued under the 2006 Plan with a weighted average exercise price of $34.63 surrendered those options in
exchange for 421,428 replacement options with an exercise price of $11.73. Accordingly, 579,072 options were added back to the plan and became available for future grant. Under the March 30, 2009 option exchange program, holders of 1,619,750
eligible options issued under the 1996 Plan at an exercise price of $25.10 surrendered those options in exchange for 988,325 replacement options under the 2006 Plan with an exercise price of $14.09. Because the 1996 Plan has expired, the cancelled
options did not become available for future grant.

Compensation expense of $13.6 million, $15.7 million, and $15.6 million
has been charged to income for stock-based compensation for the fiscal years ended September 30, 2010, 2009, and 2008, respectively. The total income tax benefit recognized in the income statement for share-based compensation was $2.8, $3.9,
and $3.7 million for the fiscal years ended September 30, 2010, 2009, and 2008, respectively. The following table summarizes compensation expense recorded in these financial statements.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Buildings and leasehold improvements includes office space that is leased under
operating leases to third parties with a historical cost of $1,463 and $1,572 and carrying amount of $791 and $985 at September 30, 2010 and 2009, respectively.

9. Intangible assets and goodwill

On June 30, 2005, Sirona Holdings
Luxco S.C.A. (Luxco), a Luxembourg-based holding entity owned by funds managed by Madison Dearborn Partners, Beecken Petty OKeefe, management and employees of Sirona, obtained control over the Sirona business. The transaction was
effected by using new legal entities, Sirona Holding GmbH (formerly Blitz 05-118 GmbH) and its wholly owned subsidiary Sirona Dental Services GmbH, to acquire 100% of the interest in Sirona Dental Systems Beteiligungs- und Verwaltungs GmbH, the
former parent of the Sirona business through a leveraged buy-out transaction (the MDP Transaction). The MDP Transaction was accounted for as a leveraged buyout transaction, in a manner similar to a business combination. Certain members
of Sirona management who were deemed to be in the control group held equity interests in Sirona Group prior to and subsequent to the MDP Transaction (Continuing Shareholders). The interests of the Continuing Shareholders have been
reflected at the predecessor basis, resulting in 9.15% of each asset and liability acquired being valued at historical cost at June 30, 2005. The remaining 90.85% interest in each asset and liability was recognized at fair value at
June 30, 2005 and the excess of purchase price over predecessor basis is presented as a separate component of shareholders equity. Intangible assets and goodwill were primarily recorded in the MDP Transaction and the reverse acquisition
of Schick on June 30, 2006.

The Company performed the required annual impairment tests as of September 30 in each
year and identified no impairment.

Amortization expense for finite-lived identifiable intangible assets for the fiscal years
ended September 30, 2010, 2009, and 2008 was $60,844, $71,486, and $91,649. The annual estimated amortization expense related to these intangible assets for the fiscal years 2011, 2012, 2013, 2014, and 2015 is $53,802, $49,238, $39,130, $32,222
and $26,102, respectively.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)



The change in the value of goodwill and of intangible assets from September 30,
2009 to September 30, 2010 is mainly attributable to foreign currency fluctuations, with an impact of $39,949 on goodwill and $43,326 on intangible assets. Goodwill has been increased by $1,221 as a result of a subsequent purchase price
adjustment for a subsidiary in China and also reduced by (i) $400 as a result of the sale of a subsidiary and (ii) $762 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.

10. Income taxes

The income tax provision is comprised of the following:

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)



In assessing the recoverability of deferred tax assets, management considers whether it
is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon sufficient taxable income within the carry-back years and the generation of future
taxable income during the periods in which those temporary differences and tax loss carry-forwards become deductible. Management considers taxable income in the carry-back years, if carry back is permitted in the tax law, the projected future
taxable income (including the realization of future taxable temporary differences), and tax planning strategies in making this assessment.

As of September 30, 2010, the Company had $8,523 of gross tax loss carry-forwards subject to expiration as follows:

|                   |  |        |       | 

The Company recognized a valuation allowance of $2,208 at September 30, 2010, ($4,731 at
September 30, 2009) on deferred tax assets of $2,512 ($5,223 at September 30, 2009) predominantly relating to tax loss carry-forwards, as management believes that it is more likely than not that the benefits of those existing tax loss
carry-forwards will not be realized within the period those tax losses are deductible.

Non-deductible expenses primarily include stock option expense in the U.S. The income tax provision at
September 30, 2009 includes credits of $1,623 to adjust for prior year items.

In August 2007 a new tax law was enacted
in Germany which has been applicable since Sironas fiscal year 2008. The new German tax law introduced earnings stripping rules (Zinsschranke) that may limit the deductibility of interest. For the fiscal years ended
September 30, 2010 and 2009, the Companys deductibility of interest was not limited as a result of this German tax law.

The components of income before taxes are:

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.

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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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.

14. Deferred income

On June 30, 2005, Sirona and its largest distributor, Patterson, amended the terms of an existing distribution agreement to extend
Pattersons rights as exclusive distributor of certain Sirona products within the U.S. and Canada from October 1, 2007 through September 30, 2017. As consideration for the extension of its exclusivity rights, Patterson made a one-time
payment of $100 million to Sirona in July 2005. Sirona recorded the full amount of the payment as deferred income and started amortizing the amount on a straight-line basis over ten years on October 1, 2007. In the event of termination by
Patterson for certain breaches of contract by Sirona, Sirona has to refund to Patterson the unearned portion of the $100 million payment as liquidated damages. Depending on the reason for termination, the amount of liquidated damages declines
(i) on a straight line basis beginning in fiscal year 2008 or (ii) by $15 million per year in each of fiscal year 2008 through fiscal year 2012 and by $5 million per year thereafter. Sirona accounts for the deferred income related to the
Patterson payment as a monetary liability. The deferred income is amortized and recognized as other operating income on a straight line over the term of the contract ($10 million per year). The current portion of deferred income is reported within
Accrued liabilities and deferred income in the consolidated balance sheets. Effects of remeasurement of the amount from U.S. Dollar to Euro are reflected currently in the statement of income. Sirona recognized $5.7 million in foreign currency
transaction losses in the fiscal year ended September 30, 2010, and $1.5 million and $1.4 million in foreign currency transaction gains in the fiscal years ended September 30, 2009 and 2008, respectively, and recognized $10.0 million of
the Patterson deferred income in the consolidated statements of income for the fiscal years ended September 30, 2010, 2009, and 2008.

Stock options to acquire 85,000, 359,500, and 2,861,625 shares of Sironas common stock that were
granted in connection with the 2007 Plan were not included in the computation of diluted earnings per share for the fiscal years ended September 30, 2010, 2009, and 2008, respectively, because the options underlying exercise prices were
greater than the average market price of Sironas common stock for the period.

16. Commitments and contingencies

Operating lease commitments

The Company leases certain buildings, vehicles
and IT equipment from unrelated third parties. The leases are non-cancellable and have terms of more than one year. During the fiscal year ended September 30, 2010, leasing expense was $10,135 (year ended September, 30, 2009: $9,118; year ended
September, 30, 2008: $8,436).

In July 2005, Sirona entered into a sale and leaseback agreement regarding unused land on the
site of the major facility in Bensheim. The land was sold to an unrelated property development company, who constructed an office building on the site based on Sironas specifications. Sirona leased the property from the property development
company through an 18-year lease. Under the terms of the lease, rent is fixed at Euro 1,202 ($1,641 at the U.S. Dollar/Euro exchange rate of September 30, 2010) per annum until 2013. After 2013, rent is subject to adjustment according to
an inflation index. Rental payments started in April 2007 when the building was ready for occupancy. The land remains an asset on Sironas balance sheet and the building is accounted for as an operating lease.

Furthermore, the Company rents space in New York, Charlotte (USA), Salzburg (Austria) and other locations.

Future minimum lease payments under non-cancelable operating lease agreements as of September 30, 2010 are as follows:



|                          |  |        |        |

|                          |  |        |        | 

Unconditional purchase commitments

As of September 30, 2010, the Company had unconditional purchase commitments of $57,066, mainly for purchases of raw material and components, which are due over a period of from one to three years.

Contingencies

The Company may be involved in lawsuits, claims, investigations and proceedings, including patent and commercial matters that arise in the
ordinary course of business. At September 30, 2010, there are no such matters pending that the Company expects to be material in relation to its business, consolidated financial position, results of operations or cash flows.

19. Pension plans

Defined benefit plans

In Germany, the Company traditionally had an
unfunded defined benefit pension plan whose benefits are based primarily on years of service and wage and salary group. As of January 1, 2001, the Company replaced its unfunded defined benefit pension plan with a new defined contribution plan.
All new hires after that date only receive defined contributions to a pension plan based on a percentage of the employees eligible compensation. However, due to grandfathering provisions for certain existing employees hired before that date,
the Company continues to be obligated to provide pension benefits which are at a minimum equal to benefits that would have been available under the terms of the traditional defined benefit plans (Grandfathered Benefit). The Grandfathered Benefit and
contributions to the Companys pension plan made for those employees after January 1, 2001 are included in the disclosures for defined benefit plans. The Company accounts for the Grandfathered Benefit by recognizing the higher of the
defined contribution obligation or the defined benefit obligation for the minimum benefit. As of September 30, 2010 and 2009, contributions made through the defined contribution plan for those employees are adequate to cover the Grandfathered
Benefit obligation. Therefore, the Company accounts for that portion of its pension obligation as a fully funded plan with a funded status of zero.

In addition, the Company offers defined contribution benefits under the terms of a Section 401(k) plan to employees in the U.S.

The Company uses an actuarial measurement date of September 30.

The accumulated benefit obligation as of September 30, 2010 and 2009 was $51,824 and $49,401,
respectively.

To the extent the defined benefit obligation is recognized for the Grandfathered Benefit, the long-term
estimated rate of return on plan assets is 5% per annum. This rate was based on an appropriate long-term rate for the plan assets held.

The benefits expected to be paid in cash of the following five years, and in aggregate for the fiscal years thereafter, are as follows:

Plan assets consist of
insurance policies with a guaranteed minimum return by the insurance company and an excess profit participation feature for a portion of the benefits. Sirona pays the premiums on the insurance policies but does not manage the investment of the
funds; the insurance company makes all decisions on investment of funds, including the allocation to asset groups. The fair value of the plan assets such as equity securities, fixed-income investments, and others is based on the cash surrender
values reported by the insurance company.

Defined contribution plans

The Company made contributions of $557 to the German plan for the fiscal year ended September 30, 2010, and $553 to the German plan
for the fiscal year ended September 30, 2009.

Contributions to the U.S. plans were $469 for the fiscal year ended
September 30, 2010, and $548 for the fiscal year ended September 30, 2009. The Company is obligated to match employee contributions as defined in the plans.

20. Net Other Operating Income and Restructuring Costs

Net other operating income for the fiscal years ended September 30, 2010 and September 30, 2009 was $11.6 million and $5.7
million, respectively. In both periods, net other operating income included $10.0 million of income resulting from the amortization of the deferred income relating to the Patterson exclusivity payment. In the fiscal year ended September 30,
2010, net other operating income included a gain of $ 0.8 million from the release of the remaining accrued restructuring costs as well as a gain from the sale of a subsidiary in Italy of $0.9 million. In the fiscal year ended September 30,
2009, net other operating income included restructuring costs of $8.2 million, and a gain from the sale of a sales and service subsidiary in Spain of $3.9 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. In the fiscal year ended September 30, 2010, we completed our restructuring efforts and released the
remaining accrual of $ 0.8 million, as actual expenses were lower than the estimated restructuring costs. The development of restructuring costs in the current fiscal year is presented in the following table:

21. 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, 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 September 30, 2010, these contracts had notional amounts totaling $49.3 million. These agreements are relatively short-term
(generally six months).

The fair value carrying amount of the Companys derivative instruments at September 30,
2010 is described in Note 22 Fair Value Measurements.

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

22. Fair Value Measurements

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.

In the Companys September 30, 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 fair values of cash, cash equivalents, accounts receivable and accounts payable approximate their respective fair values because of the short maturity and nature of these items. The fair value of
the foreign currency forward contracts is estimated by obtaining quotes from financial institutions.

23. Segment reporting

Sirona manages its business on both a product and geographic basis and has four reporting segments; Dental CAD/CAM Systems, Imaging
Systems, Treatment Centers, and Instruments. There are two regional sales organizations, USA and Other World Markets, which distribute Sironas products globally through a network of independent distributors to dental practices, clinics and
laboratories. The Electronic Center is a shared facility that manufactures electronic components and provides services for all Sirona segments, and to a very limited extent, external parties. Further shared functions including customer service,
logistics, site management, IT and administration are operated centrally.

Description of the Companys segments

Dental CAD/CAM Systems

Dental CAD/CAM Systems products comprise CAD/CAM chairside systems for the dentist (CEREC) as well as CAD/CAM systems for the laboratories, such as inLab, inEOS and a central manufacturing service for
copings and bridge-frameworks. The CEREC system allows dentists to prepare restorations in an out-of-mouth pre-shaped process and insert them into the patients mouths during a single appointment.

Imaging Systems

Imaging systems products comprise a broad range of equipment for diagnostic imaging in the dental practice, using both film-based and
digital technologies. Sirona has developed a broad range of imaging systems for 3D, panoramic and intra-oral applications.

Treatment Centers

Sironas treatment centers comprise a broad range, from standard dentist chairs to sophisticated centers with integrated diagnostic, hygiene and ergonomic functionalities, such as Teneo, C2+ and M1+,
as well as specialist centers used for training purposes.

Instruments

Sirona offers a wide range of handpiece products, encompassing handheld and power-operated handpieces for cavity preparation, endodontics,
periodontology and prophylaxis. The handpieces are supplemented by multi-function tips, supply and suction hoses, as well as care and hygiene systems for handpiece preparation. Sironas handpieces are often sold as complete packages in
combination with treatment centers. The division also supplies parts for other divisions, especially Treatment Units (OEM turbines and tubes) and CAD/CAM Systems.

Segment results

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 MDP
Transaction. 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.

SIRONA DENTAL SYSTEMS, INC. AND SUBSIDIARIES

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)



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 fiscal year ended September 30, 2010, 2009 and 2008 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.
