Corporate
Governance and Board Matters



Board Committees and Meetings



During fiscal 2015, the Board held fifteen meetings.
At all Board meetings our independent directors meet separately without management present. All of the then current members of
our Board attended the 2014 annual meeting of stockholders. The Company has no policy regarding director attendance at its Annual
Meeting. A majority of the Board, consisting of Messrs. Beecken, Hood, Jetter, Kowaloff, Kraemer and Sullivan are “independent
directors”, as such term is defined in Rule 5605(a)(2) of the NASDAQ Listing Rules. The following table provides membership
information as of September 30, 2015 for the Audit, Compensation and Nominating and Corporate Governance committees of our Board:

* Committee Chairperson



Below is a description of the Audit, Compensation,
Nominating and Corporate Governance and Finance committees of our Board and information regarding committee meetings held in fiscal
2015.



Audit Committee. Our Audit Committee is
currently composed of three directors, Messrs. Beecken (who serves as Chairman), Hood and Kowaloff, all of whom are independent
directors as such term is defined in Rule 5605(a)(2) of the NASDAQ Listing Rules, and as required by the Audit Committee Charter.
In addition, our Board has determined that each of Messrs. Hood and Kowaloff is an “audit committee financial expert,”
as defined by the U.S. Securities and Exchange Commission (the “SEC”).



The primary function of the Audit Committee is
to serve as an independent and objective party to oversee our accounting and financial reporting processes and internal control
system; to pre-approve all auditing and non-auditing services to be provided by our independent auditor; to review and oversee
the audit efforts of our independent auditor; and to provide an open avenue of communication among the independent auditor, financial
and senior management and our Board. The Audit Committee has responsibility and authority, among other matters, to review with
our management any financial information filed with the SEC or disseminated to the public; to establish and maintain procedures
for receiving and treating complaints regarding accounting, internal accounting controls and auditing matters, and for the confidential
anonymous submission by employees of concerns regarding these matters; to appoint, determine funding for and oversee our independent
auditor; to review, in consultation with the independent auditor and our accounting personnel, the integrity of our financial reporting
processes; and to review in advance any proposed transaction between us and any related party. A copy of our Audit Committee Charter
can be found on our corporate website at www.sirona.com. The Audit Committee met eight times during the fiscal year ended September
30, 2015.



Compensation Committee. Our Compensation
Committee is currently composed of four directors, Messrs. Sullivan (who serves as Chairman), Hood, Kowaloff and Kraemer, all of
whom are independent directors as such term is defined in Rule 5605(a)(2) of the NASDAQ Listing Rules, and as required by the Compensation
Committee Charter. The Compensation Committee is comprised solely of independent directors. The Compensation Committee has oversight
responsibility relating to the compensation of our executive officers and directors and the administration of awards under our
2015 Long-Term Incentive Plan. In August 2011, our Board expanded the number of members of the Compensation Committee from three
to four directors. On July 1, 2013, the Board amended and restated our Compensation Committee Charter to expand the responsibilities,
duties and authority of the Compensation Committee in compliance with the new NASDAQ Listing Rules related to compensation committees.
In particular, under the amended and restated Compensation Committee Charter, the Compensation Committee (i) has the authority,
in its sole discretion, to retain or obtain the advice of a compensation consultant, legal counsel or other adviser, (ii) is directly
responsible for the appointment, compensation and oversight of the work of any compensation consultant, legal counsel and other
adviser, (iii) will receive appropriate funding, as determined by the Compensation Committee, for payment of reasonable compensation
to a compensation consultant, legal counsel or any other adviser; and (iv) will select, or receive advice from, a compensation
consultant, legal counsel or other adviser, other than in-house legal counsel, only after taking into consideration factors related
to the independence of such compensation consultant, legal counsel or other adviser, as required by the NASDAQ Listing Rules. A
copy of our amended and restated Compensation Committee Charter can be found on our corporate website at www.sirona.com. The Compensation
Committee met six times during the fiscal year ended September 30, 2015.

Compensation Committee Interlocks and Insider
Participation. No member of the Compensation Committee is an officer or employee, or former officer or employee, of our Company
or any of our subsidiaries. No interlocking relationship existed during the fiscal year ended September 30, 2015 between the members
of our Board or Compensation Committee and the board of directors or compensation committee of any other company, nor have any
other “compensation committee interlocks” existed in the past.



Nominating and Corporate Governance Committee.
Our Nominating and Corporate Governance Committee is currently composed of four directors, Messrs. Kraemer (who serves as Chairman),
Jetter, Kowaloff and Sullivan, all of whom are independent directors as such term is defined in Rule 5605(a)(2) of the NASDAQ Listing
Rules, and as required by the Nominating and Corporate Governance Charter. The Nominating and Corporate Governance Committee is
comprised solely of independent directors. The former Nominating Committee was established by resolution of our Board on August
3, 2004. On July 30, 2010, our Board replaced the Nominating Committee with the Nominating and Corporate Governance Committee and
reduced the number of members of the Nominating and Corporate Governance Committee to four directors. The functions of the Nominating
and Corporate Governance Committee are to (i) establish criteria for selecting candidates for nomination to our Board and actively
seek candidates who meet those criteria, (ii) recommend nominees to our Board and (iii) advise the Board on corporate governance
matters and Board performance matters. The Nominating and Corporate Governance Committee will consider director candidates who
have relevant business experience, are accomplished in their respective fields and who possess the skills and expertise to make
a significant contribution to our Board, us and our stockholders. Director nominees should have relevant business or other experience,
knowledge about issues affecting us and the ability and willingness to apply sound and independent business judgment. The Company’s
Corporate Governance Guidelines provide that directors should be selected so that the Board is a diverse body, with diversity reflecting
gender, ethnic background, country of citizenship and professional experience. The Nominating and Corporate Governance Committee
does not discriminate on the basis of race, gender or ethnicity. The Nominating and Corporate Governance Committee will establish
procedures by which it will exercise oversight of the evaluation of the Board and management. The Nominating and Corporate Governance
Committee will also establish procedures for the Board, on at least an annual basis, to evaluate the Board’s performance
and to make any recommendations to the Board that the Committee deems appropriate regarding improvements of the Board’s operations.
The Nominating and Corporate Governance Committee will consider nominees for election or appointment to our Board that are recommended
by stockholders, provided that a complete description of the nominees’ qualifications, experience and background, together
with a statement signed by each nominee in which he or she consents to act as such, accompanies the recommendations. Such recommendations
should be submitted in writing to the attention of the Nominating and Corporate Governance Committee, c/o Corporate Secretary,
Sirona Dental Systems, Inc., 30-30 47th Avenue, Suite 500 Long Island City, NY 11101 and should not include self-nominations. A
copy of our Nominating and Corporate Governance Committee Charter can be found on our corporate website at www.sirona.com. The
Nominating and Corporate Governance Committee met three times in the fiscal year ended September 30, 2015.



Attendance at Board and Committee Meetings.
Each of our directors attended all meetings of the Board during the fiscal year ended September 30, 2015. In addition, each of
our directors attended all meetings held by all committees of the Board on which such director served during the fiscal year ended
September 30, 2015.



Board of Directors and Management Following the Merger



Immediately following the effective time of the
Merger, the board of directors of the combined company will consist of eleven members, including: (i) six of the directors of DENTSPLY
immediately prior to the merger, to be selected by DENTSPLY, of which one will be Brett Wise and (ii) five of the directors of
Sirona immediately prior to the merger, to be selected by Sirona, of which one will be Mr. Slovin. All other director designees
of DENTSPLY and Sirona will qualify as “independent directors” under NASDAQ rules. Upon completion of the Merger, one
director designated by Sirona will serve as the lead independent director of the combined company. As of the date of this joint
proxy statement/prospectus, other than Mr. Wise, in the case of DENTSPLY, and Mr. Slovin, in the case of Sirona, neither DENTSPLY
nor Sirona has made a determination as to which directors will be appointed to the board of directors of the combined company.

Table of Contents











Upon completion of the merger, Mr. Wise will
serve as executive chairman of the board of directors of the combined company and Mr. Slovin will serve as the chief executive
officer of the combined company. Through the third anniversary of the effective date of the Merger, the board of directors of the
combined company may only replace, remove, alter the responsibilities and authorities or grant conflicting responsibilities or
authorities of Mr. Wise, Mr. Slovin, or the lead independent director, as applicable, by the affirmative vote of the greater of
(i) at least 70% of the entire board of directors and (ii) eight directors.



The combined company’s management team
will include from DENTSPLY, Christopher T. Clark (the current president and chief financial officer of DENTSPLY) as president and
chief operating officer, technologies of the combined company, and James G. Mosch (the current executive vice president and chief
operating officer of DENTSPLY) as president and chief operating officer, dental and healthcare consumables of the combined company,
and from Sirona, Mr. Michel (the current executive vice president and chief financial officer of Sirona) as executive vice president
and chief financial officer of the combined company. As of the date of this Form 10-K/A, other than Messrs. Wise, Clark and Mosch,
in the case of DENTSPLY, and Messrs. Slovin and Ulrich, in the case of Sirona, neither DENTSPLY nor Sirona has made a determination
as to which officers will be appointed to the management team of the combined company.



Corporate Governance Guidelines



The Board of Directors adopted Corporate Governance
Guidelines, a copy of which is available on our Internet website at www.sirona.com. Our Corporate Governance Guidelines address
topics such as (i) the role and responsibilities of the Board of Directors, (ii) the definition of independence, (iii) the selection
of Board of Director nominees, (iv) Board membership criteria, (v) Board leadership, (vi) Board meetings, (vii) committees, (viii)
director compensation, (ix) orientation and continuing education of directors, (x) management development and succession planning,
(xi) attendance of directors at the Annual Meeting of Stockholders, (xii) directors’ access to management and independent
advisors, (xiii) evaluation of the Board of Directors and committees and (xiv) submission of director resignations. The Corporate
Governance Guidelines were revised in fiscal 2013 with the following changes: we included a director resignation policy which states
that any nominee for director in an uncontested election who receives a greater number of votes “withheld” from his
or her election than votes “for” such election is required to tender his or her resignation to the Board of Directors,
and we added the position of senior independent director, who will be appointed annually by the independent directors, and who
is responsible for presiding at all meetings of the Board at which the Chairman is not present, including executive sessions of
the independent directors.



The Board of Directors also adopted Stock Ownership
Guidelines to ensure that the interests of the executive officers and directors are aligned with those of stockholders. The individual
stock ownership guideline level for each executive officer is equal to the number of shares equivalent to: (i) six (6) times the
annual base salary for the Chief Executive Officer; or (ii) one (1) times the annual base salary of any executive officer other
than the Chief Executive Officer. The individual stock ownership guideline level for each director is equal to the number of shares
equivalent to five (5) times the annual cash retainer payable to such director. In addition to the ownership guidelines, each executive
officer and director is required to retain an amount equal to 50% of the net shares received as a result of the exercise, vesting
or payment of any Company granted equity until such time as the ownership guideline is met. A copy of the Stock Ownership Guidelines
is available on our Internet website at www.sirona.com.



Code of Ethics



On June 2, 2004, by resolution of our Board,
we adopted a code of ethics governing the conduct of our personnel, including our principal executive officer, principal financial
officer, principal accounting officer or controller, or persons performing similar functions. A copy of the current code of ethics
is available on our website at www.sirona.com. In addition, a free copy of the code may be obtained by stockholders upon request
by contacting Jonathan Friedman, General Counsel of the Company, at (718) 482-2011.



In the event that any amendment is made to the
code of ethics, and such amendment is applicable to our principal executive officer, principal financial officer, principal accounting
officer or controller, or persons performing similar functions, we shall disclose the nature of any such amendment on our website
within four business days following the date of the amendment. In the event that we grant a waiver, including an implicit waiver,
from a provision of the code of ethics, to our principal executive officer, principal financial officer, principal accounting officer
or controller, or persons performing similar functions, we shall disclose the nature of any such waiver, including the name of
the person to whom the waiver is granted and the date of such waiver, on our website within four business days following the date
of the waiver. Our website address is www.sirona.com.

Stockholder Communications with the Board of Directors



Historically, we have not adopted a formal process
for stockholder communications with our Board. Nevertheless, every effort has been made to ensure that the views of stockholders
are heard by our Board or individual directors, as applicable, and that appropriate responses are provided to stockholders in a
timely manner. We believe our responsiveness to stockholder communications to our Board has been excellent, and to date, we have
not considered it necessary to adopt a formal process. Nevertheless, during the upcoming year the Board will continue to monitor
whether it would be appropriate to adopt a formal process for stockholder communications with the Board.



Report of the Audit Committee of the Board of Directors



In executing its responsibilities, the Audit
Committee has reviewed and discussed our audited financial statements with our management. The Audit Committee has also discussed
with the Company’s independent auditor the overall scope and plans for their audits of the Company. Furthermore, the Audit
Committee has discussed with our independent auditor the matters required to be discussed by SAS 61, as amended. In addition, the
Audit Committee has received written disclosures and a letter from our independent auditor delineating all relationships between
them and us, consistent with the applicable requirements of the Public Company Accounting Oversight Board regarding the independent
auditor’s communications with the Audit Committee concerning independence, and has discussed with them matters pertaining
to their independence. The Audit Committee also considered whether the additional services unrelated to audit services performed
by KPMG during the fiscal year ended September 30, 2015 were compatible with maintaining their independence in performing their
audit services. In addition, the Audit Committee met with the independent auditor, with and without management present, to discuss
the results of their examinations, their evaluations of the Company’s internal controls, and the overall quality of the Company’s
financial reporting.



Based upon the reviews and discussions referred
to above, the Audit Committee recommended to our Board of Directors that the audited financial statements be included in our Annual
Report on Form 10-K for the fiscal year ended September 30, 2015 for filing with the SEC. The Audit Committee and Board of Directors
have also recommended the selection of KPMG as our independent auditor for the fiscal year ending September 30, 2016.

Inc.:

Leadership Structure



Our Board is committed to adopting governance
policies and practices that promote the most effective and ethical management of the Company. In addition, the Board believes that
it is important to retain flexibility to determine the Company’s optimal leadership structure and to choose the best qualified
person(s) to serve in the roles of Chief Executive Officer and Chairman of the Board. Consequently, after our former Chairman and
Chief Executive Officer, Mr. Fischer, retired in February 2013, the Board determined that the designation of an independent, Non-Executive
Chairman represented the optimal leadership structure for the Company. The directors believe that this role provides the Board
with independent leadership and allows Mr. Slovin, the Company’s Chief Executive Officer, to concentrate on the Company’s
business operations. Therefore, Mr. Jetter, who served as a director since April 2010, was appointed to the role of Non-Executive
Chairman of the Board following our Annual Meeting on February 20, 2013.



We recognize that different board leadership
structures may be appropriate for companies in different situations and believe that no one structure is suitable for all companies.
Because the leadership structure that is appropriate for a company can also change over time, we intend to review our leadership
structure annually to determine if it is the most appropriate one for the Company.



Risk Oversight



Our Board is responsible for overseeing the Company’s
risk management process. The Board focuses on the Company’s general risk management strategy, the most significant risks
facing the Company, and ensures that appropriate risk mitigation strategies are implemented by management. The Board is also apprised
of particular risk management matters in connection with its general oversight and approval of corporate matters.

Table of Contents











The Board has delegated to the Audit Committee
oversight of the Company’s risk management process. Among its duties, the Audit Committee (a) reviews with management Company
policies with respect to risk assessment and management of risks that may be material to the Company, including the risk of fraud,
(b) reviews the integrity of the Company’s financial reporting processes, both internal and external, including reviewing
management’s report on its assessment of the effectiveness of internal control over financial reporting as of the end of
each fiscal year, (c) reviews the Company’s major financial risk exposures and the steps management has taken to monitor
and control such exposures and (d) the Company’s compliance with legal and regulatory requirements. The Audit Committee is
also responsible for reviewing major legislative and regulatory developments that could materially impact the Company’s contingent
liabilities and risks. Our other Board committees also consider and address risk as they perform their respective committee responsibilities.
All committees report to the full Board as appropriate, including when a matter rises to the level of a material or enterprise
level risk.



The Company’s management is responsible
for day-to-day risk management. Our Internal Audit area serves as the primary monitoring and testing function for company-wide
policies and procedures, and manages the day-to-day oversight of the risk management strategy for the ongoing business of the Company.
This oversight includes identifying, evaluating, and addressing potential risks that may exist at the enterprise, strategic, financial,
operational, and compliance and reporting levels.



We believe the division of risk management responsibilities
described above is an effective approach for addressing the risks facing the Company and that our Board leadership structure supports
this approach.



Section
16(a) Beneficial Ownership Reporting Compliance



Section 16(a) of the Exchange Act, requires our
directors and executive officers, and persons who own more than 10% of a registered class of our equity securities, to file with
the SEC initial reports of ownership and reports of changes in ownership of our Common Stock and other of our equity securities.
Specific due dates for these reports have been established, and we are required to disclose any failure to file by these dates
during fiscal 2015. Our officers, directors and greater than 10% stockholders are required by the SEC regulations to furnish us
with copies of all Section 16(a) forms they file.



To our knowledge, based solely on a review of the copies of such
reports furnished to us and representations that no other reports were required, during the fiscal year ended September 30, 2015,
all Section 16(a) filing requirements applicable to our officers, directors and greater than 10% beneficial owners were complied
with.

Say-on-Frequency and Say-on-Pay



Consistent with the desire of the stockholders
(per the Say-on-Frequency vote in early 2011), we have adopted the practice of conducting an annual non-binding advisory vote on
NEO compensation. The Compensation Committee has and will continue to monitor the results of the annual advisory Say-on-Pay proposal
and incorporate such results as one of many factors considered in connection with the discharge of its responsibilities, although
no such factor is assigned a quantitative weighting. As in prior years, Sirona received near universal support for the our fiscal
2014 compensation program, we, in keeping with evolving corporate governance best practices continue to consider appropriate changes
to our compensation program.



Independent Compensation Consultant



Since October 2007, the Compensation Committee
has retained PM to provide advice and recommendations with respect to the competitiveness of our executive and director compensation
programs. The Compensation Committee directly engaged PM to conduct competitive market assessments for our NEO group in fiscal
2008, 2011, 2012, 2013 and 2014. Additionally, PM was also engaged to provide competitive market assessments of our Non-Employee
Director Compensation program in fiscal 2008, 2011, 2013 and 2015. PM has never performed any services other than executive and
director compensation consulting for us, and performed its services only on behalf of and at the direction of the Compensation
Committee.



The Compensation Committee believes that there
was no conflict of interest between the compensation consultant and the Compensation Committee during the year ended September
30, 2015. In reaching this conclusion, the Compensation Committee has analyzed whether the work of PM as a compensation consultant
has raised any conflict of interest, taking into consideration the following factors: (i) the provision of other services to us
by PM; (ii) the amount of fees from us paid to PM as a percentage of PM’s total revenue; (iii) the policies and procedures
of PM that are designed to prevent conflicts of interest; (iv) any business or personal relationship of PM or the individual compensation
advisors employed by PM with any of our executive officers; (v) any business or personal relationship of the individual compensation
advisors with any member of the Compensation Committee; and (vi) any of our stock owned by PM or the individual compensation advisors
employed by PM.

Compensation Philosophy: We do business
in a competitive and dynamic industry. Our continued success in such an environment depends, in large part, on our ability to attract
and retain talented senior executives. In order to align the compensation delivered to these executives with stockholder interests,
a significant portion (approximately 80% of total target compensation) is variable (short- and long-term incentives) and based
on corporate performance. As a result, the Compensation Committee’s compensation policies are designed to:



(i)           Provide a competitive level of compensation
to attract and retain talented management;



(ii)          Reward senior executives for corporate
performance;



(iii)         Align the interests of senior executives
with our stockholders in order to maximize stockholder value;



(iv)         Motivate executive officers to achieve
our business objectives; and



(v)         Reward individual performance.



To achieve these compensation objectives, the
Compensation Committee has developed a compensation program for the NEOs generally consisting of base salary, annual cash bonus
and long-term incentive compensation in the form of stock options, restricted shares/units and/or performance-contingent shares.



Target compensation levels for the NEOs approximate
the market as follows:



•           Base Salary: 55th percentile of Market



•           Annual Cash Bonus: 65th percentile
of Market



•           Long-term Incentive: 65th percentile
of Market



Base salary levels are positioned just above
market median to account for our greater product complexity and broader geographic reach. However, as mentioned above, compensation
is primarily driven by incentive awards tied to our performance. As in past years, the Compensation Committee continues to believe
that our growth targets justify positioning target incentive compensation (short- and long-term) at above-median levels.



The resulting target total compensation pay
mix for the President and CEO, Jeffrey T. Slovin, is:



•           Base Salary: 15%



•           Annual Cash Bonus: 15%



•           Long-term Incentive: 70%



The average total compensation pay mix for the
other NEOs is structured to be:



•           Base Salary: 23%



•           Annual Cash Bonus: 16%



•           Long-term Incentive: 61%



The Compensation Committee believes that placing
heavier weight on long-term incentives helps ensure strong alignment with creating long-term value for stockholders.



Review of Market Data for Peer Companies



Compensation levels for our named executive
officers are determined based on a number of factors, including a review of the compensation levels in the marketplace for similar
positions. The Peer Group was generally consistent with the Peer Group established in 2007, but updated to take into account changes

Base Salaries (Short-term Fixed Pay)



The Compensation Committee generally reviews
base salary levels on an annual basis and determines if increases are warranted to align with prevailing market levels. For fiscal
2015, the Company increased base salaries by 3% for NEOs to align with market-based merit increases. Note, fiscal 2015 values are
lower for Messrs. Michel, Petersohn and Berthan as a result of the changing FX rate.



|Executive     | Fiscal 2014 Base  Salary |         |   | Fiscal 2015 Base Salary |   |         | Increase % |

Non-Equity Performance Compensation (Short-Term Variable Pay)



The Compensation Committee believes that annual
bonuses can serve an important function by adding a fiscal performance-based incentive to an executive’s compensation package.
To that end, we maintain a bonus program for the NEOs: the Executive Bonus Plan (“Executive Plan”). As discussed in
more detail below, the Fiscal 2015 bonus program is based on the following metrics: Sales growth (25%), Operating Income Margin
(25%), Diluted EPS (25%) and Free Cash Flow (25%).



Executive Bonus Plan



The purpose of the Executive Plan is to provide
to senior executive officers selected by the Compensation Committee cash bonus compensation that is (1) performance based and (2)
competitive at target performance with the cash bonuses paid to similarly situated senior executives. The Compensation Committee
annually determines target performance metrics based upon budgetary estimates of financial performance approved by the Board of
Directors in the first quarter of each fiscal year. The target bonus amount of each participant is a percentage of such participant’s
annual base salary.



The Compensation Committee determined for fiscal
2015 that the target bonus amounts were:



•        Mr. Slovin: 100% of base salary



•        Mr. Michel: 70% of base salary



•        Mr. Friedman: 60% of base salary



•        Mr. Petersohn: 70% of base salary



•        Mr. Berthan: 70% of base salary



Consistent with our compensation philosophy,
target bonus amounts are within +/-15% of the market 65th percentile.



The financial performance metrics used to measure
and reward performance under the Executive Plan has four major components: a Sales Growth Metric, an Operating Income Margin Metric,
a Diluted Earnings Per Share Metric and a Free Cash Flow Metric.

Table of Contents













Sales Growth Metric. Each participant
would earn 25% of his or her target bonus if actual fiscal year 2015 Sales Growth achieved target of 8.0%. Sales Growth attainment
below 4.0% would yield zero payout (Threshold) and Sales Growth at or above 10.0% would result in a capped payout of 2x target
(Maximum); with payout levels interpolated on a straight-line basis based on performance attainment between threshold-target and
target-maximum.



|Fiscal
    2015 Sales Growth |  | %
    of Target Bonus | 
|---------------------------- |  | --------------------- | 
|Below 4.0%                   |  | 0%                    |

|Greater than 10.0%           |  | 50%                   | 



Operating Income Margin Metric. Each
participant would earn 25% of his or her target bonus if actual fiscal year 2015 Operating Income Margin achieved target of 24.0%.
Operating Income Margin below 23.0% would yield zero payout (Threshold) and Operating Income Margin at or above 25.0% would result
in a capped payout of 2x target (Maximum); with payout levels interpolated on a straight-line basis based on performance attainment
between threshold-target and target-maximum.



|Fiscal
    2015 Operating Income Margin |  | %

|Greater than 25.0%                      |  | 50%                                                        | 



Diluted Earnings Per Share Metric. Each
participant would earn 25% of his or her target bonus if actual fiscal year 2015 Adjusted Diluted EPS, as defined under the Executive
Plan, achieved target of $4.00. Diluted Earnings Per Share
below $3.92 would yield zero payout (Threshold) and Diluted Earnings Per Share above $4.14 would result in a capped payout of 2x
target (Maximum); with payout levels interpolated on a straight-line basis based on performance attainment between threshold-target
and target-maximum.



|Fiscal
    2015 Diluted Earnings Per Share |  | % of
    Target Bonus | 
|------------------------------------------ |  | --------------------- | 
|Below $3.92                                |  | 0%                    |

|Greater than $4.14                         |  | 50%                   | 



Free Cash Flow Metric. Each participant
would earn 25% of his or her target bonus if actual fiscal year 2015 Free Cash Flow achieved target of$190
million. Free Cash Flow below $170 million would yield zero payout (Threshold) and Free Cash Flow at or above $210 million would
result in a capped payout of 2x target (Maximum); with payout levels interpolated on a straight-line basis based on performance
attainment between threshold-target and target-maximum.

Final bonus payout is 100% formula-based (i.e.,
the sum of the payout levels attained on each of the performance metrics) with no element of individual performance considered
in the award determination.



2015 Fiscal Year Performance and Bonus Results
under Executive Plan. The fiscal 2015 results for the Sales Growth Metric, the Operating Income Margin Metric, the Diluted
Earnings Per Share Metric and the Free Cash Flow Metric, as derived from our audited fiscal 2015 financial statements in accordance
with the definitions approved by the Compensation Committee, were 8.8%, 22.7%, $3.98 and $188.9 million, respectively. After applying
the calculations set forth in the charts above for performance below, at or above target, the Compensation Committee determined
that the bonus payable to each of the participating named executive officers for each of the Sales Growth Metric, the Operating
Income Margin Metric, the Diluted Earnings Per Share Metric and the Free Cash Flow Metric, as a percentage of target bonus, was
approximately 140%, 0%, 87.50% and approximately 97.25%, respectively. Total payout was funded at 81.20%.



Pursuant to the foregoing, each of the covered
executives earned the following:



|Executive     |  | Target Bonus |         | Actual Bonus Earned |   | Actual as % of Target |

*            Note: bonus amounts for Mr. Michel, Mr.
Berthan and Mr. Petersohn were paid in Euros. The rest were paid in U.S. dollars.



There are no payments under the Executive Plan
to any person upon termination of employment (for any reason) or upon a change in control of the Company, however, participants
may be eligible for such payments under their employment or other agreements with the Company. Please see “Employment Agreements”
below.



Equity Awards (Long-term Variable Pay)



As discussed above, the Compensation Committee
targets long-term incentive compensation at the 65th percentile of the Peer Group. Additionally, the Compensation Committee has
determined that granting long-term incentives on an annual basis, rather than on a periodic basis, is more aligned with market
practice and is in the best interest of stockholders.



In furtherance of our desire to award the appropriate
mix of stock options, time-vested restricted stock/units and performance-based shares to its NEOs, in fiscal 2015 the Compensation
Committee decided to grant an equity mix of stock options, time-vested restricted stock unit and performance units to each of the
named executive officers in order to provide an appropriate balance between performance, desire for stockholder alignment and retention.



Our use of multiple equity vehicles aligns with
our desire to align the long-term interests of our stockholders with our interests and those of our senior executives. Stock options
are inherently performance-oriented and aligned with stockholder interest because stock price appreciation above the exercise price
is required before an executive realizes any value. Unlike stock options, a restricted stock unit award has some value regardless
of stock price volatility thereby enhancing retention during times of stock price volatility. This retention feature is further
enhanced by requiring the first tranche (1/3rd) of restricted stock units to vest two years following the grant date and annually
thereafter (as opposed to stock options which vest 25% one year following the grant date and 25% each year thereafter). Lastly
performance units tied to absolute 3 year sales growth (25%), absolute 3 year EPS growth (25%) and relative 3 year total stockholder
return performance (50%) versus the SPDR S&P Healthcare Equipment Index provide a direct alignment with business fundamentals
and relative total stockholder return. Given their direct linkage to our financial and total stockholder return performance, these
units have a payout potential ranging from 0-200% of the targeted number of granted units (see Grants of Plan-Based Awards table
for actual grant amounts at target).

We do not publicly disclose specific long-term
incentive plan targets on a prospective basis due to potential competitive harm. Revealing specific objectives prospectively would
provide competitors and other third parties with insights into our confidential planning process and strategies, thereby causing
competitive harm. Given that we are only in the second year of the performance share program, the result of the fiscal 2014 grant
is not yet certain.



Compensation Recoupment Policy



In the event of a material restatement of our
financial results, the Board will consider whether any executive officer received compensation based on the original financial
statements because it appeared he or she achieved financial performance targets which in fact were not achieved based on the restatement.
The Board will also consider the accountability of any executive officer whose acts or omissions were responsible in whole or in
part for the events that led to the restatement and whether such acts or omissions constituted misconduct.



Possible actions of the Board may include the
following: (i) the recoupment of all or part of any bonus or other compensation paid to the executive officer that was based upon
the achievement of financial results that were subsequently restated, (ii) disciplinary actions, up to and including termination,
and/or (iii) the pursuit of other available remedies.



Severance Payments and Change in Control



In March 2008, the Compensation Committee, after
review of the competitive market assessment conducted by PM, determined that Mr. Slovin should receive payments of up to 24 months
annual base salary and two times target bonus in the year of termination in the event that he was terminated without cause or if
he terminated his employment for good reason. The Compensation Committee also decided that equity awards held in the Company by
Mr. Slovin would be accelerated in the event of a change in control. Mr. Slovin’s employment agreement already provided for
such acceleration of equity awards held by him.



On December 2, 2008, the Compensation Committee
approved amendments to employment agreement of Mr. Slovin for the purposes of providing the revised severance and change in control
benefits described in the paragraph above. Additionally, Mr. Slovin’s employment agreement was further amended to reflect
his promotion to Chief Executive Officer.



On September 15, 2015, the Company amended Mr.
Slovin’s employment agreement to provide for termination by Mr. Slovin for good reason if certain minimum compensation terms
were not granted to Mr. Slovin in a new employment agreement effective the time of the Merger. For further detail see terms set
forth under the section “Employment Agreements” below.

Other Compensation



Executive pension plans are common in European
companies but are declining in the United States. In March 2008, the Compensation Committee, after review of the competitive market
assessment conducted by PM, decided that Ms. Blank should be enrolled in a defined contribution retirement savings plan because
she is not eligible to participate in the Company’s 401(k) plan. The Compensation Committee believes that such a retirement
savings plan provides a competitive benefit to our Europe-based named executive officers. While such benefit was authorized by
the Compensation Committee in fiscal 2008, the retirement saving plan became available to our Europe-based named executive officers
during fiscal 2009. For a description of this plan, see “Nonqualified Defined Contribution and other Nonqualified Deferred
Compensation.” The Compensation Committee also determined that the Company should provide payments on behalf of some named
executive officers for private health care insurance coverage. In fiscal 2015, payment $37,403 was made on behalf of Mr. Slovin.
The Compensation Committee also decided in March 2008, after review of the competitive market assessment conducted by PM, to continue
the Company’s current practice of providing limited auto, housing and tax advisory services to its named executive officers.
These perquisites facilitate the performance of our named executive officers’ managerial duties and provide for competitive
total compensation when compared to the total compensation of the Peer Group.



Modification of Compensation Policies



The Omnibus Budget Reconciliation Act of 1993
includes potential limitations on tax deductions for compensation in excess of $1,000,000 paid to our executive officers. The Compensation
Committee has analyzed the impact of this provision of the tax law on our compensation policies, has determined that historically
the effect of this provision on the taxes paid by us has not and would not have been significant and has decided for the present
not to modify our compensation policies based on such provision. In the event that a material amount of compensation might potentially
not be deductible, it will consider what actions, if any, should be taken to seek to make such compensation deductible without
compromising its ability to motivate and reward excellent performance.



Tax Equalization Agreements



In fiscal 2010, the Company entered into an
agreement with Mr. Slovin providing for tax equalization. These payments were in recognition of the fact that such executive is
required to spend an increased percentage of his time outside his home country and were designed to make him whole on an after-tax
basis.



In connection with his September 2010 appointment
to President of the Company, Mr. Slovin agreed to be relocated to Bensheim, Germany for two years. During the period of relocation,
we agreed to make Mr. Slovin whole on an after-tax basis for German employment income and other applicable taxes on his remuneration
in excess of the tax that he would owe if his income was subject only to federal, state and local taxation applicable to Mr. Slovin
prior to his relocation. This tax equalization payment is calculated by the our outside accounting firm and paid with the monthly
payroll. On October 1, 2012, we entered into a Letter Amendment to Mr. Slovin’s existing Amended and Restated Employment
Agreement, providing that Mr. Slovin’s relocation to Bensheim, Germany will be extended until March 31, 2013. On May 7, 2013,
we entered into an amendment to Mr. Slovin’s existing Amended and Restated Employment Agreement, providing that Mr. Slovin’s
relocation to Germany is to be extended for a period to be determined within the sole discretion of Mr. Slovin. Furthermore, in
the event that our housing, car lease, insurance, maintenance or tuition payments are deemed to be income to Mr. Slovin, Mr. Slovin
will receive additional payments to make him whole on an after-tax basis.



Report of the Compensation Committee of the Board of Directors



The Compensation Committee has reviewed and
discussed with management the Compensation Discussion and Analysis provided above. Based on its review and discussions, the Compensation
Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in the proxy statement
and the Company’s Annual Report on Form 10-K for its 2015 fiscal year.

Stockholder Approval of Executive Compensation



Pursuant to section 14A of the Securities Exchange
Act, the Company provides stockholders with the opportunity to cast an advisory (non-binding) vote to approve the compensation
of the Company’s named executive officers. As an advisory vote, this proposal is non-binding. However, the Board of Directors
and the Compensation Committee value the opinions of stockholders and will consider the outcome of the vote when making future
compensation decisions for the named executive officers. In light of the results of the stockholder’s non-binding advisory
vote at the 2010 Annual Meeting with respect to the frequency with which stockholders will vote for the approval of the compensation
of the Company’s named executive officers, the Company currently intends to hold an annual non-binding advisory vote on such
named executive officer compensation.

least one, of the members of the Company’s Board of Directors, excluding employee, determines that (a) the employee has

employment for “good reason” subject to the notice and cure provisions set forth in the Employment Agreement. Mr.

Pension Benefits



None of the
named executive officers participate in a defined benefit pension plan.



Nonqualified Defined Contribution
and other Nonqualified Deferred Compensation



Mr. Michel
participates in a defined contribution retirement savings plan (the “Defined Contribution Plan”). While such benefit
was authorized by the Compensation Committee in fiscal 2008, no contributions have been made to any of current NEOs.



Employer
contributions are used to make payments on an insurance policy. Pursuant to the terms of the policy, the accumulated benefit bears
interest as determined pursuant to the insurance policy. This policy has been pledged to the beneficiaries. The only payments
to which the beneficiaries are entitled are the proceeds of the insurance policy and the employer has no further obligation. Beginning
on the first month following the 65th birthday of such executive, the benefits under the Defined Contribution Plan become automatically
due and payable. The executive may also elect to have such benefits begin at any time after his or her 60th birthday. If the executive
elects to receive benefits early, the accumulated funds are converted into a retirement pension using actuarial methods at that
time. In the case of inability to work, the surrender value of the insurance becomes due and payable. If the executive dies prior
to retirement a fully insured death lump sum is converted into an annuity for the executive’s spouse. If the executive dies
following retirement, 60% of the accumulated benefit is converted into an annuity for the executive’s spouse. If the beneficiary
leaves the Company prior to reaching retirement age, the accumulated benefit is paid to the executive when the executive reaches
the normal retirement age. Alternatively, a private continuation of the contract can be agreed.

Potential Payments upon Termination
or Change in Control



The following
tables provide information on the compensation payable to each named executive officer upon voluntary termination, disability,
death, termination for cause or upon a change in control. The amounts shown assume that the termination was effective as of September
30, 2015 and are estimates of the amounts that would be paid to the named executive officer upon his or her separation from the
Company. The actual amounts to be paid to each named executive officer can only be determined at the time of such person’s
separation from the Company. See “Employment Agreements.”
