EXPLANATORY NOTE



This Amendment No. 1 on Form 10-K/A (this
“Amendment”) amends the Annual Report on Form 10-K of Rofin-Sinar Technologies, Inc. (the “Company”) for
the fiscal year ended September 30, 2015 that was filed with the Securities and Exchange Commission (“SEC”) on November
30, 2015 (the “Original Filing”; and as amended by this Amendment, “this Annual Report”). Because the Company
has determined that it will not file its definitive proxy statement within 120 days of the end of its fiscal year ended September
30, 2015, the Company is filing this Amendment to include the information required by Part III and not included in the Original
Filing.



In addition, pursuant to the rules of the
SEC, Item 15 of Part IV of the Original Filing has been amended to contain currently dated certifications from our Chief Executive
Officer and Chief Financial Officer, as required by Sections 302 and 906 of the Sarbanes-Oxley Act of 2002 with respect to this
Form 10-K/A. The currently dated certifications of our Chief Executive Officer and Chief Financial Officer are attached to this
Form 10-K/A as Exhibits 31.1, 31.2, 32.1 and 32.2. Except with regard to the currently dated certifications included under said
Item 15 and as set forth in Part III below, no other changes are made to the Original Filing other than the deletion of the reference
on the cover of the Original Filing to the incorporation by reference of the Company’s definitive proxy statement into Part
III of the Original Filing. Unless expressly stated, this Amendment does not reflect events occurring after the filing of the Original
Filing, nor does it modify or update in any way the disclosures contained in the Original Filing.

DIRECTOR INDEPENDENCE AND CORPORATE GOVERNANCE



Director Independence



We believe that the Company benefits from having a strong and
independent Board of Directors. For a director to be considered independent, the Board must determine that the director does not
have any direct or indirect material relationship with the Company that would affect his or her exercise of independent judgment.
On an annual basis, the Board reviews the independence of all directors under guidelines established by NASDAQ and in light of
each director's affiliations with the Company and members of management. This review considers all known relevant facts and circumstances
in making an independence determination. Based on this review, the Board has made an affirmative determination that all directors,
other than Dr. Wirth, and Messrs. Merk and Baasel, are independent. Mr. Merk was determined to lack independence due to his status
as the Company's President and Chief Executive Officer ("CEO"). Dr. Wirth and Mr. Baasel lack independence due to their
previously held positions within the Company as noted above in this Item 10 and, in the case of Mr. Baasel due to certain rental
payments he receives from the Company as noted below in Item 13 "Certain Relationships and Related Transactions."



Audit Committee Financial Expert



The Board of Directors has determined that Daniel J. Smoke,
Chairman of the Audit Committee, qualifies as an "audit committee financial expert" as such term is defined in the applicable
Securities and Exchange Commission Audit Committee rules and that he has the requisite level of financial sophistication required
under the listing standards of NASDAQ.



Code of Business Conduct and Ethics



The Board of Directors and the Company are committed to good
corporate governance practices. The Company's Code of Business Conduct and Ethics requires management, including the Company's
CEO, Chief Financial Officer and Controller, and employees to abide by high standards of business conduct and ethics. The Code
of Business Conduct and Ethics is available in the Investors Relations section of the Company's web site at www.rofin.com



Executive Sessions of Non-Management Directors



Executive sessions of non-management directors (consisting of
all independent directors) are regularly scheduled and held at each meeting of the Board of Directors.



Stockholder Communications with the Board



Any stockholder who wishes to send any communications to the
Board, a particular committee of the Board or a particular director should also deliver such communications to the Secretary of
the Company at 40984 Concept Drive, Plymouth, MI 48170. The Secretary is responsible for determining, in consultation with other
officers of the Company, counsel, and other advisers as appropriate, which stockholder communications will be relayed to the Board.



Risk Oversight Process



Our Board of Directors has the primary responsibility for risk
oversight of the Company as a whole. However, the Board has delegated primary oversight responsibility to the Audit Committee.
The Audit Committee is responsible for overseeing risks associated with financial and accounting matters, including compliance
with all legal and regulatory requirements and internal control over financial reporting. In addition, the Audit Committee has
oversight responsibility for the Company's overall business risk management process, which includes the identification, assessment,
mitigation and monitoring of key business risks on a company-wide basis. On at least an annual basis the Audit Committee reviews
the key business process risks and controls of the Company, and approves the internal audit control testing plan. On a quarterly
basis, the internal audit department reports the progress of the annual control testing to the Audit Committee. At the year-end
meeting, the Company's internal audit department and the external auditors report their respective findings to the Audit Committee.
Any significant findings are followed up on and corrected under the direction of the Audit Committee or Executive Management. The
Board believes that the current leadership structure of the Board supports effective oversight of the Company's risk management
processes described above by providing independent leadership at the Board committee level, with ultimate oversight by the full
Board as led by the Chairman, and the President and CEO.

BOARD OF DIRECTORS AND COMMITTEES



During the fiscal year ended September 30, 2015, the Board of
Directors held twenty meetings. All directors attended at least 75% of the meetings of the Board of Directors and meetings of the
committees of which they are members. To conduct its business, the Board maintains three standing committees: an Audit Committee,
a Compensation Committee, and a Nominating Committee. In addition, from time-to-time, the Board may determine that it is appropriate
to form an additional committee or committees of the Board to address a particular matter or matters not specific to, or determined
to be appropriate for, one of its standing committees. All committees report on their activities to the Board.



We do not have a formal policy regarding attendance by directors
at annual meetings. However, our directors are expected to attend board meetings, our Annual Meeting of Stockholders and meetings
of committees on which they serve and to spend the time needed and meet as frequently as necessary to properly discharge their
responsibilities. All directors who were on the Board at the time of the last Annual Meeting of Stockholders attended the meeting,
with two directors attending remotely by telephone.



The role of Chairman of the Board is currently held by Dr. Peter
Wirth, while the role of Chief Executive Officer is held by Thomas Merk. We separate the roles of Chief Executive Officer and Chairman
of the Board of Directors in recognition of the differences between the two roles. The Chief Executive Officer is responsible for
setting the strategic direction for the Company and the day to day leadership and performance of the Company, while the Chairman
of the Board of Directors provides guidance to the Chief Executive Officer and sets the agenda for Board of Directors meetings
and presides over meetings of the full Board of Directors and executive sessions of the Board of Directors. Our Chief Executive
Officer serves on our Board of Directors, which we believe helps the Chief Executive Officer serve as a bridge between management
and the Board of Directors, helping to ensure that both groups act with a common purpose. We believe that the Chief Executive Officer's
presence on the Board of Directors enhances his ability to provide insight and direction on important strategic initiatives to
both management and the independent directors.

BOARD COMMITTEES



Audit Committee



The Audit Committee's responsibilities include recommending
an independent registered public accounting firm to the Board of Directors, reviewing the proposed scope of such audit, approving
the audit fees, overseeing and evaluating the performance of the independent registered public accounting firm, overseeing the
accounting and financial reporting policies and internal control systems of the Company, reviewing and approving transactions between
the Company and its directors, officers and affiliates, considering whether the provision by the external auditors of services
related to the annual audit and quarterly reviews is consistent with maintaining the auditors' independence, and reviewing annually
the adequacy of the Audit Committee Charter. The Board of Directors has adopted a written Charter for the Audit Committee. A copy
of the Audit Committee Charter is available in the Investor Relations section of the Company's website at www.rofin.com.



During fiscal year 2015, the members of the Audit Committee
were Messrs. Reins, Smoke and Willis and Dr. Fantone. Mr. Smoke has been identified as an "audit committee financial expert"
under applicable Securities and Exchange Commission ("SEC") audit committee rules. All members of the Audit Committee
are independent directors within the meaning of Rule 5605(a)(2)of the NASDAQ Marketplace Rules. During fiscal year 2015, Mr. Smoke
was Chairman of the Audit Committee. In fiscal year 2015, the Audit Committee held four meetings.



The Nominating Committee



The Nominating Committee is responsible for assisting the Board
by actively identifying individuals qualified to become Board members and recommending to the Board of Directors nominees for election
at the next annual meeting of stockholders. The Nominating Committee has two primary methods for identifying candidates (other
than those proposed by the Company's stockholders, as discussed below). First, on a periodic basis, the Nominating Committee solicits
ideas for possible candidates from a number of sources including members of the Board; senior level Company executives; individuals
personally known to the members of the Board; and research. Second, the Nominating Committee may from time to time use its authority
under its charter to retain, at the Company's expense, one or more search firms to identify candidates (and to approve such firms'
fees and other retention terms). The Nominating Committee will also consider nominees recommended by stockholders. Stockholders
wishing to submit nominations should notify the Company at its principal offices (Attention: Cindy Denis, Secretary, 40984 Concept
Drive, Plymouth, MI 48170) of their intent to do so. To be considered by the Nominating Committee, nominations must be received
on or before the deadline for receipt of stockholder proposals. Any candidate submitted by a stockholder must meet the definition
of an "independent director" under NASDAQ rules.



The Nominating Committee will consider all candidates identified
through the processes described above, and will evaluate each of them, including incumbents, based on the same criteria. Once the
nominee has been contacted and accepts to be considered as a nominee, the Nominating Committee reviews and analyzes the nominee's
resume, credentials, qualifications and characteristics to serve on the Board, and the expertise the nominee would offer the Board
of Directors and the Company. While the Nominating Committee does not have a formal policy with respect to diversity, the Board
and the Committee believe that it is essential that Board members represent diverse business backgrounds, experience, talents,
and perspectives. In considering candidates for the Board, the Nominating Committee considers the entirety of each candidate's
credentials. Director nominees are selected based on, among other things, their ability to represent the best interests of the
Company's stockholders and not just one particular constituency; demonstrated sound business judgment and an inquiring mind; expertise
that adds to the composition of the Board; professional experience, education, and their interest in, and capacity for understanding
the complexities of, the operation of the Company; personal and professional character and actions appropriate for a Board member
and the reputation of the Company; and their being prepared to participate fully in Board activities, including active membership
on at least one Board committee and attendance at, and active participation in, meetings of the Board and the committee of which
he or she is a member. These individuals can bring considerable experience to the impartial oversight of the Company's operations.
The Board of Directors has adopted a written Charter for the Nominating Committee. A copy of the Nominating Committee Charter is
available in the Investor Relations section of the Company's website at www.rofin.com.



The members of the Nominating Committee, during fiscal year
2015, were Dr. Fantone and Messrs. Reins, Smoke and Willis, each of whom is an independent director within the meaning of Rule
5605(a)(2) of the NASDAQ Marketplace Rules. Messrs. Reins, Willis, and Smoke and Dr. Fantone are not employees of the Company.
During fiscal year 2015, Dr. Fantone was Chairman of the Nominating Committee. In fiscal year 2015, the Nominating Committee held
nine meetings.

The Compensation Committee



The Compensation Committee is responsible for providing a general
review of the Company's compensation and benefit plans and ensuring that they meet financial and strategic objectives.



The responsibilities of the Compensation Committee also include
administering the Annual Incentive Plan and the 2007 Incentive Stock Plan and 2015 Incentive Stock Plan (all of which are described
below), including selecting the officers and salaried employees to whom awards will be granted and making such awards. The Board
of Directors has adopted a written charter for the Compensation Committee. A copy of the Compensation Committee Charter is available
in the Investor Relations section of the Company's website at www.rofin.com. The members of the Compensation Committee are Messrs.
Reins, Willis, and Smoke and Dr. Fantone, each of whom is an independent director within the meaning of Exchange Act Rule 10C-1(b)(1)
and Rules 5605(a)(2) and 5605(d)(2) of the NASDAQ Marketplace Rules. During fiscal year 2015, Mr. Willis was Chairman of the Compensation
Committee. In fiscal year 2015, the Compensation Committee held ten meetings.



Compensation Committee Matters



Scope of Authority



The Compensation Committee acts on behalf of the Board of Directors
of the Company and, by extension, the stockholders to establish the compensation of executive officers of the Company and provides
oversight of the Company's global compensation philosophy. The Compensation Committee also acts as the oversight committee with
respect to our 2015 Incentive Stock Plan (including all amendments to the Plan) discussed below covering Named Executive Officers
("NEOs") and other employees. In general, the Committee may rely on recommendations from the Chief Executive Officer
regarding participant selection and award determination. However, the Compensation Committee makes final determinations regarding
any compensation decisions.



The Compensation Committee has the sole discretion to retain
or obtain the advice of a compensation consultant, legal counsel or other adviser (each a "Compensation Adviser"), and
the direct responsibility for the appointment, compensation and oversight of the work of any Compensation Adviser it retains. Additionally,
the Compensation Committee's charter requires the Committee to take into account the following six factors before hiring any Compensation
Adviser:



| | • | the provision of other services to the Company or its subsidiaries by the person that employs the Compensation Adviser;
| | - | -----------------------------------------------------------------------------------------------------------------------

| | • | the amount of fees received from the Company or its subsidiaries by the person that employs the Compensation Adviser, as a
percentage of the total revenue of the person that employs the Compensation Adviser;
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | • | the policies and procedures of the person that employs the Compensation Adviser that are designed to prevent conflicts of interest;
| | - | -----------------------------------------------------------------------------------------------------------------------------------

| | • | any business or personal relationship of the Compensation Adviser with a member of the Committee;
| | - | -------------------------------------------------------------------------------------------------

| | • | any stock of the Company owned by the Compensation Adviser; and
| | - | ---------------------------------------------------------------

| | • | any business or personal relationship of the Compensation Adviser or the person employing the Compensation Adviser with an
executive officer of the Company.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------



The Committee's Processes



The Compensation Committee has established a number of processes
to assist it in ensuring that the Company's executive compensation program is achieving its objectives. Among those are:



| | • | Meetings. The Compensation Committee meets several times each year. Compensation Committee agendas are established in consultation
with the Committee Chair. The Compensation Committee also meets in executive session following regular meetings, as deemed appropriate.
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | • | Assessment of Company Performance. The Compensation Committee uses Company performance measures in establishing total compensation
ranges. The Compensation Committee considers various measures of Company performance, including revenues or net income.
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | • | Assessment of Individual Performance. Individual performance has a strong impact on the compensation of employees, including
the NEOs. During the course of each year, the Compensation Committee meets with the Chief Executive Officer to review recommendations
on changes, if any, in base salary of each NEO (other than the Chief Executive Officer).
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



- 8 -






| | • | Stockholder Advisory Votes. The Committee considers the results of the most recent advisory vote of the stockholders on executive
compensation in making compensation determinations and recommendations. However, the Committee is not bound by the results of an
advisory vote.
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | • | Consideration of Compensation Arrangements and their Relationship to the Encouragement of Risk-Taking Behavior. The Committee
reviews the Company's incentive compensation arrangements to determine whether they encourage excessive risk-taking. The Committees
reviews and discusses at least annually the relationships between risk management policies and practices and compensation, and
evaluates compensation policies and practices that could mitigate any such risk.
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Compensation Committee Interlocks And Insider Participation



Messrs. Willis, Reins and Smoke and Dr. Fantone are the members
of the Compensation Committee of the Board of Directors of the Company. None of such individuals is an officer of the Company.
There are no compensation committee interlocks involving executive officers of the Company.



Section 16(a) Beneficial Ownership Reporting Compliance



Section 16(a) of the Securities Exchange
Act of 1934, as amended, requires the Company's officers and directors, and persons who own more than ten percent of a registered
class of the Company's equity securities, to file reports of securities ownership and changes in such ownership with the Securities
and Exchange Commission (the "SEC"). Officers, directors and greater than ten percent stockholders are also required
by rules promulgated by the SEC to furnish the Company with copies of all Section 16(a) forms they file.



Based solely upon a review of the copies
of such forms, the absence of a Form 3, Form 4 or Form 5 or written representations that no Form 4's or 5's were required, the
Company believes that, with respect to the fiscal year ended September 30, 2015, its officers, directors and greater than ten percent
beneficial owners complied with all applicable Section 16(a) filing requirements.



Item 11. 	EXECUTIVE COMPENSATION



COMPENSATION DISCUSSION AND ANALYSIS



For the fiscal year ended September 30, 2015, which we refer
to as "fiscal year 2015", our NEOs were:



| | • | Mr. Thomas Merk, our President and Chief Executive Officer, effective July 1, 2015
| | - | ----------------------------------------------------------------------------------



| | • | Mr. Gunther Braun, our former President and Chief Executive Officer, who was succeeded by Mr. Merk effective July 1, 2015
| | - | -------------------------------------------------------------------------------------------------------------------------



| | • | Ms. Ingrid Mittelstaedt, our Chief Financial Officer and Executive Vice President of Finance and Administration
| | - | ---------------------------------------------------------------------------------------------------------------

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



Following this "Compensation Discussion and Analysis",
you will find a series of tables containing specific information about the compensation earned, awarded or paid during fiscal year
2015. Please refer to those tables when considering the discussion below.



Executive Summary



In determining fiscal year 2015 compensation for our senior
executives, the Compensation Committee of the Board, comprised solely of independent directors, considered the operating plans
and targets established by management for the fiscal year, the actual performance of the Company during that period, and the external
market conditions of the Company's served markets. The Compensation Committee seeks to compensate our NEOs (and other key employees)
in a way that would enable us to retain them as our senior management team through the challenges and appropriately recognize their
individual contributions to the Company performance, consistent with our overall business objectives and our stockholders' best
interests.

In March 2015, we held a stockholder advisory vote on the compensation
of our named executive officers, commonly referred to as a say-on-pay vote. Our stockholders approved the compensation of our named
executive officers, with approximately 94% of stockholder votes cast in favor of our 2015 say-on-pay resolution. As we evaluated
our compensation practices and talent needs throughout 2015, we were mindful of the strong support our stockholders expressed for
our pay for performance compensation philosophy. As a result, the Committee decided to retain our general approach to executive
compensation, with an emphasis on short- and long-term incentive compensation that rewards our most senior executives when they
deliver value for our stockholders. In addition, when determining how often to hold a stockholder advisory vote on executive compensation,
the Board took into account the strong preference for an annual vote expressed by our stockholders at our 2011 Annual Meeting.
Accordingly, the Board determined that we will hold an annual advisory stockholder vote on the compensation of our named executive
officers until the next say-on-pay frequency vote.



In making its compensation decisions for fiscal year 2015, the
Compensation Committee paid particular attention to the following areas of achievement:



| | • | Market share gains in the fiber and ultra-short pulse laser markets;
| | - | --------------------------------------------------------------------

| | • | Cost reduction achievement in fiber lasers; and
| | - | -----------------------------------------------

| | • | Company-wide initiatives to increase productivity and reduce expenses.
| | - | ----------------------------------------------------------------------



The Compensation Committee also took into account the following
threshold, target, and maximum level metrics and the performance of the Company as compared to these metrics:



| | • | Sales: Sales targets were weighted at 30% for the Incentive Plan with the sales target threshold being set at $540 million
and maximum set at $600 million. If the Company achieved its target (set at $560 million), the potential payout would be 100%,
if the Company achieved its stretch goal (set at $580 million), the potential payout would be 110%, and if the Company achieved
its maximum (set at $600 million), the potential payout would be up to 150% of the incentive sales target. The actual net sales
for fiscal year 2015 were approximately $519.6 million, a decrease of approximately 2% over fiscal year 2014.
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | • | Net Income Improvement: Net income targets were weighted at 70% for the Incentive Plan. The 2015 net income threshold
was set at $40 million, and the net income maximum was set at $57 million. If the Company achieved its target (set at $44.9 million),
the potential payout would be 100%, if the Company achieved its stretch goal (set at $50 million), the potential payout would be
110%, and if the Company achieved its maximum (set at $57 million), the potential payout would be up to 150% of the incentive sales
target. The actual net income for fiscal year 2015 was $41.3 million, an increase of approximately 64% over fiscal year 2015.
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Consistent with our historical compensation practices, our fiscal
year 2015 compensation program featured the following attributes:



| | • | A balanced mix of annual cash and long-term equity incentives that reward our NEOs for current performance and align their
compensation with longer term performance and shareholder value creation.
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | • | No NEO severance plans or agreements, and no "golden parachute" agreements with cash payouts for the NEOs conditioned
upon a change of control.
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------



| | • | A structure for NEO compensation that attempts to comply with Internal Revenue Code requirements to tax deductibility.
| | - | ----------------------------------------------------------------------------------------------------------------------



| | • | Option plan awards were also allocated, pursuant to our option plan, by the Compensation Committee. These awards were principally
based on the performance of the NEO and certain other key employees since the Compensation Committee determined that these individuals
were instrumental in achieving the Company's performance in fiscal year 2015.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Compensation Philosophy and Objectives



Our philosophy is to align NEO compensation with our strategic
objectives, while providing competitive compensation that enables us to attract and retain top quality executive talent. To that
end, the primary objectives of our NEO compensation policy are to:



| | • | Provide compensation in a manner that allows for management to share in the risks and potential rewards of our enterprise growth.
| | - | ---------------------------------------------------------------------------------------------------------------------------------



| | • | Maintain the common interest of NEOs and our stockholders in our long-term growth through a focus on stock options.
| | - | -------------------------------------------------------------------------------------------------------------------



- 10 -






| | • | Provide incentives for short-term success-oriented operation through our annual cash incentive program.
| | - | -------------------------------------------------------------------------------------------------------



| | • | Attract and retain individuals with the leadership and technical skills to carry the Company into the future and to grow the
business and create long-term shareholder value for our stockholders.
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Principal Components of Executive Compensation



The principal components of our executive compensation program
are:



| | • | Base salary
| | - | -----------



| | • | Annual cash incentive plan; and
| | - | -------------------------------



| | • | Long-term, equity-based incentives
| | - | ----------------------------------



Mix of Compensation Components



NEO compensation is based on our pay-for-performance philosophy,
which rewards executive performance that correlates closely with the achievement of both shorter-term performance objectives and
longer-term shareholder value. To this end, a substantial portion of our executives' annual and long-term compensation is at-risk,
meaning that the ultimate value of their compensation is largely or entirely dependent on our overall growth and success, thereby
aligning their interests with those of our stockholders. We believe that this benefits our Company and stockholders by ensuring
that our management team has strong commitment to the health of our entire Company.



Target Pay Philosophy - How We Use Our "Comparator Group"



Our NEO compensation is reviewed against executive compensation
at a designated set of publicly-traded companies (which we call our "Comparator Group"). Historically, our Comparator
Group was constructed using companies that are reasonably similar to us in terms of their total revenues, manufacturing focus and
profitability and for which executive officer positions were comparable to ours in terms of breadth, complexity and scope of responsibilities.



Historically, our Comparator Group included manufacturing companies
with an optical, electronics and/or engineering focus having revenues ranging from $400 million to approximately $1.0 billion with
return on sales of approximately 10% or higher over a three-year period. The latest NEO compensation comparative analysis was completed
in December 2011. Consistent with the approximate historical practice, it is expected that the next NEO compensation comparative
analysis will occur in 2016.



In December 2011, the Company hired Radford, an independent
third party compensation consulting firm, to assist with the NEO compensation analysis. Radford provided an analysis of data from
peer companies' proxy filings with respect to similarly situated individuals at a Comparator Group of companies and compensation
survey sources. The Comparator Group in this analysis included manufacturing companies with a semiconductor and/or capital equipment
background having revenues ranging from approximately $200 million to approximately $1.6 billion. The Comparator Group consisted
of the following companies: Coherent Inc., Newport Corp., GSI Group, FLIR Systems, Inc., Aeroflex Inc., MTS Systems, Inc., Littlefuse
Inc., Altra Holdings Inc., Blount International, Cymer, Electro Scientific Industries, FEI Company, Finisar, II-VI Inc., IPG Photonics,
Measurement Specialties, MKS Instruments, NN Inc., and Veeco Instruments. This Comparator Group is consistent with the Comparator
Group used in the 2007 NEO compensation analysis. The results of this third party study have shown that the Company's NEO total
compensation is positioned at the 50th percentile of the Comparator Group. This report supports the Company's NEO compensation
packages in comparison to the Comparator Group.



The Compensation Committee retained Radford in November 2012
to provide an update to the executive compensation review conducted in December 2011. This update was intended to present the Compensation
Committee with the appropriate facts and data to make decisions regarding executive compensation.



The Compensation Committee retained Radford in fiscal year 2015
to advise the Committee on the appropriate compensation as the Company transitioned to a new Chief Executive Officer, including
change of control benefits for Mr. Merk and other NEOs.



The Compensation Committee evaluates the total compensation
package of our NEOs against the total compensation package of NEOs in the Comparator Group. The individual components of the total
package and the relative size of each component to the total compensation package are used in this consideration, although the
Committee does not seek to match any particular percentile among the Comparator Group. Instead, the Committee considers information
on our Comparator Group in order to get a general sense of



- 11 -






compensation trends in our industry and the appropriateness
of our NEO compensation packages. The Compensation Committee relies on proxy statements, executive compensation surveys and other
published information for data on current market pay practices and trends.



Components of Executive Compensation for fiscal year 2015



As is our general philosophy, for fiscal year 2015, the Compensation
Committee used a three-pronged approach to our executive compensation program: 1) base salary; 2) annual cash incentive plans;
and 3) long-term equity-based compensation. We believe that this program balances the mix of cash and equity compensation, and
leaves an appropriate portion of each NEOs compensation package "at-risk". Historically, executive compensation for a
particular fiscal year is reviewed and finalized by the Compensation Committee during its first meeting in the then current fiscal
year.



Base Salary



The Compensation Committee considers relevant market pay practices
when setting executive compensation to ensure our ability to recruit and retain high caliber talent. The Compensation Committee
sets base salary levels for executive officers each year based on a number of factors, including the status of the competitive
marketplace for such positions, the responsibilities of the position, the experience of the individual, the individual's performance
and contributions to the Company during the past year, and our desire to maintain internal equity in pay structure in relationship
to other executives within the Company and against the executive compensation of our Comparator Group. Base salary is the one fixed
component of our executives' total direct compensation, in contrast to incentive compensation, which is based on our performance.
The Compensation Committee reviews the base salaries of executive officers annually and whenever an executive is promoted. The
Compensation Committee meets with the Chief Executive Officer to review recommendations on changes, if any, in base salary of each
NEO (other than the Chief Executive Officer).



The Compensation Committee reviews and approves changes in the
base salary of the Chief Executive Officer. Our NEOs' base salaries trend towards the low end of the range of base salaries in
our Comparator Group for that position.



For more information regarding our NEOs' base salaries for fiscal
year 2015, see the "Summary Compensation Table" appearing below in this Annual Report.



Cash Incentive Plan



The Compensation Committee has established a Cash Incentive
Plan for our NEOs in order to align executive compensation with the Company's revenue, operating profit and net income objectives.



Under the Cash Incentive Plan, actual bonus payouts are determined
by the Compensation Committee based upon the actual performance of the NEO against the targeted goals. The Chief Executive Officer
approves all individual awards under the Cash Incentive Plan except his own and the NEOs', which are approved by the Compensation
Committee in its sole discretion. The Cash Incentive Plan is available to all NEOs and selected other members of the Company's
senior management. Awards to the NEOs under the Cash Incentive Plan paid for fiscal year 2015 appear in the Summary Compensation
Table under the "Non-Equity Incentive Plan Compensation" column. The selected participants receive incentive awards designed
to focus management's attention and effort on the attainment of pre-established annual performance goals.



Target Opportunities. Each participant in the Cash Incentive
Plan is assigned a target award opportunity, expressed as a percentage of the annual base salary. For fiscal years 2015 and 2014,
the target award opportunity for Mr. Braun was 70% of his base salary, the target award opportunities for Messrs. Hefter, Merk,
Molnar and Ms. Mittelstaedt were 50% of their base salaries, and the target award opportunity for Mr. Seifert was 40% of his base
salary. After becoming the Company's Chief Executive Officer effective July 1, 2015, Mr. Merk's target award opportunity was raised
to 70% of his base salary for the proportionate remaining three months of fiscal year 2015.



Pre-Established Performance Goals. For Messrs. Merk,
Hefter, Molnar and Seifert, and Ms. Mittelstaedt, the performance goals are based upon consolidated revenues and consolidated net
income for the fiscal year. In addition, Messrs. Molnar's and Seifert's performance goals include pre-established individual goals
which are determined to be important in relationship to the position they maintain within the Company.



For each metric, a specific target performance goal and a defined
performance range around the target are established. The performance range consists of a threshold, minimum performance level,
and a maximum performance level for each NEO. The cash incentive award is guaranteed if the applicable targets are reached. Details
of these metrics are included in the Executive Summary appearing earlier in this Compensation Discussion and Analysis.



- 12 -






For fiscal year 2015, if we reached our threshold targets,
Mr. Braun would have been entitled to 35% of his base salary; Messrs. Hefter, Merk and Molnar, Ms. Mittelstaedt would have been
entitled to 25% of their base salaries, and Mr. Seifert would have been entitled to 20% of his base salary. If we reached our target
goals, Mr. Braun would have been entitled to 70% of his base salary; Messrs. Hefter, Merk and Molnar, and Ms. Mittelstaedt would
have been entitled to 50% of their base salaries, and Mr. Seifert would have been entitled to 40% of his base salary. If we reached
the stretch performance target, Mr. Braun would have been entitled to 77% of his base salary; Messrs. Hefter, Merk and Molnar
and Ms. Mittelstaedt would have been entitled to 55% of their base salary, and Mr. Seifert would have been entitled to 44% of his
base salary. If we reached the maximum performance target, Mr. Braun would have been entitled to 105% of his base salary;
Messrs. Hefter, Merk and Molnar and Ms. Mittelstaedt would have been entitled to 75% of their base salaries. Subsequent to becoming
the Company's Chief Executive Officer, the percentages for Mr. Merk were increased to those previously assigned for Mr. Braun,
for the proportionate part of the 2015 fiscal year during which Mr. Merk was CEO.



In fiscal year 2015, the Compensation Committee also included
six-month performance goals, that if achieved, could add an additional 20% to the above targets.



The Compensation Committee does have "negative" discretion
to reduce the size of any award if the relevant targets are met. Additionally, the Compensation Committee has the discretion to
provide an award given the overall performance of the Company if specific target goals are not met.



Our target goals are intended to be attainable yet challenging.
However, they are set high enough that significantly exceeding them would require performance in excess of our expectations. We
believe that if financial targets are not attainable, the Cash Incentive Plan will lose the motivational effect it was designed
to achieve and payouts will lag behind competitive market levels.



Long-Term Incentive Compensation - Stock Options



We believe that long-term equity incentive compensation is an
integral component of our compensation program because it has the effect of recruiting, retaining and motivating high-quality employees.
In addition, we believe that long-term incentive compensation aligns executives' interests with the interests of stockholders,
and rewards the achievement of the Company's long-term strategic goals. Grants of long-term incentive awards are based on Company
performance, and targeted at levels that approximate market value of equity incentive compensation for executives holding comparable
positions at companies in the Comparator Group, utilizing the same compensation data used for setting total annual compensation.
In November of each fiscal year, the Compensation Committee reviews and approves the long-term incentive compensation to be granted
to executives and other eligible employees who participate in the Company's long-term incentive programs. Generally, in recent
years, stock options have been granted to executive officers as a compensation component over the vesting period of the options,
generally five years.



All equity awards granted in fiscal year 2015 were granted from
our 2007 Incentive Stock Plan and 2015 Incentive Stock Plan. Some features of our stock option program include:

For additional information concerning the timing of grants of
stock options, see "Equity Grant Practices" below.



In November 2014, the Committee awarded stock options from our
2007 Incentive Stock Plan to each of the NEOs as follows: Mr. Braun 40,000 shares; Mr. Merk and Ms. Mittelstaedt 30,000 shares;
Mr. Molnar 25,000 shares; Mr. Hefter 20,000 shares; and Mr. Seifert 5,000 shares. In July 2015, the Committee awarded Mr. Merk
an additional 20,000 shares from our 2015 Incentive Stock Plan upon being named as President and Chief Executive Officer of the
Company. We determined the size of each NEO's grant based on our previous year's performance and the relative performance of each
NEO and his or her seniority and responsibilities. In addition, the Committee considered the historical equity compensation awards
by companies in our Comparator Group.



Although the Compensation Committee has the authority under
our 2007 Incentive Stock Plan and our 2015 Incentive Stock Plan to grant stock appreciation rights, stock grants, and stock units
in addition to stock options, in recent years we have used only stock options because we believe that options provide NEOs the
best opportunity to purchase and maintain an equity position in the Company and to share in the appreciation of the value of our
Common Stock. However, we may grant other forms of equity



- 13 -






compensation in the future. We do not currently have any stock
ownership guidelines or requirements in place for our executive officers; however, we have designed our equity incentive compensation
to encourage stock ownership by management.



Equity Grant Practices



Historically, the Company has issued stock options primarily
in one of three situations: (1) to employees periodically as an incentive for continued, productive employment and retention; (2)
to new employees as a component of an offer of employment and an incentive to attract them to the Company and (3) to new employees
in connection with an acquisition as an incentive for continued productive employment with the Company after the acquisition is
complete. All stock options are issued with an exercise price equal to the closing market value of a share of our Common Stock
on the date of grant.



Stock options are granted, at the discretion of the Compensation
Committee, to groups of employees from time to time at a regularly scheduled meeting of the Compensation Committee. The exact amount
of these grants to NEOs in 2015 is shown in the "Grants of Plan Based Awards" table appearing below in this Annual Report.
The Compensation Committee approves all grants to employees and no authority to make grants has been delegated to management. Stock
options may be granted to new employees as a component of their overall compensation package. These option grants are approved
by the Compensation Committee.



The Company may also issue options as a component of an acquisition.
When this occurs, the options are approved by the Compensation Committee at a special meeting or as part of a regular meeting.
No such options were issued during fiscal year 2015.



Long-Term Incentive Compensation-Pension Plans



RSL Pension Plan



Mr. Hefter and Ms. Mittelstaedt participate in the Rofin-Sinar
Laser GmbH Pension Plan (the "RSL Pension Plan") for RSL executives, an unfunded plan in accordance with the typical
practices of German companies. The RSL Pension Plan provides pensions to participants who (i) retire on or after age 60 or terminate
employment due to a permanent disability and (ii) have served at least 10 years with RSL at the time of separation.



The annual benefits payable under the RSL Pension Plan, which
commence at the statutory retirement age of 65 for Mr. Hefter and 67 for Ms. Mittelstaedt (according to German law), are based
upon the age at which the participant leaves RSL.



Book reserves are kept to record benefits accruals under the
RSL Pension Plan. Mr. Hefter and Ms. Mittelstaedt joined or were deemed to have joined (as applicable) the RSL Pension Plan on
October 1, 1984 and January 1, 1997, respectively. Assuming retirement at or after age 60, Mr. Hefter and Ms. Mittelstaedt would
receive a monthly pension benefit of $997 and $666, respectively (at the weighted average Euro/U.S. dollar exchange rate in effect
during the fiscal year ended September 30, 2015).



Rofin-Sinar Inc. Pension Plan



In 1996 we adopted a defined benefit plan for employees of Rofin-Sinar
Inc. known as the Rofin-Sinar Inc. Pension Plan (the "RSI Plan"). Under the RSI Plan, employees receive annual pension
benefits equal to the product of (i) the sum of 1.125% of the first $12,000 of "average final compensation" and 1.5%
of "average final compensation" in excess of that amount, and (ii) the number of years of service in which the employee
was employed by a participating employer. Average final compensation is based upon the period of four consecutive plan years out
of the last ten full plan years preceding the employee's retirement which produces the highest amount. Mr. Molnar is currently
the only NEO participating in the RSI Plan. The RSI plan was frozen and a nonqualified benefit plan was created to ensure employees
who were in the RSI plan would receive the same level of benefits. The only difference in the new plan is that it requires a lump
sum payment upon termination.



Assuming retirement at or after age 62, Mr. Molnar would receive
an estimated monthly benefit of $4,454.



Perquisites and Other Benefits



During fiscal year 2015, we did not provide perquisites or personal
benefits to executive officers, except those required under the separation agreement with Mr. Braun, other than leased automobiles,
as disclosed in the Summary Compensation Table. As part of the separation agreement with Mr. Braun, the Company purchased Mr. Braun's
former leased car and transferred ownership of that car to Mr. Braun. The value of the car has been disclosed in the Summary Compensation
Table.

Employment Agreements with Named Executive Officers



Messrs. Merk and Hefter, and Ms. Mittelstaedt have employment
agreements with us, under which they are entitled to specified base salaries, adjusted by the Compensation Committee, plus the
opportunity to participate in the Cash Incentive Plan. Each employment agreement has an indefinite term, subject to termination
by either the Company and RSL or the executive upon two years' prior written notice, in the case of Mr. Merk; upon two years' prior
written notice to the end of the year, in the case of Mr. Hefter; and one year's written notice to the end of the fiscal year in
the case of Ms. Mittelstaedt. In accordance with the employment agreements, each executive has agreed (i) not to disclose or exploit
any of the Company's Confidential Information (as defined therein), and (ii) to assign to the Company all inventions or improvements
made by the executive in the course of his or her employment with the Company, and not to compete with the Company for a six month
period after the completion of his or her applicable term of employment. During the six month non-competition period, the executive
is generally entitled under German law to receive half of his or her monthly salary. The employment agreements do not provide for
severance. Mr. Molnar is subject to a written offer letter specifying his base salary plus the opportunity to participate in the
Cash Incentive Plan. Mr. Seifert has an employment agreement with Nufern, a wholly-owned subsidiary of the Company, which provides
for severance payments equal to one year’s salary in the event he is terminated without cause or resigns for good cause.



Change-In-Control Arrangements and Agreements



The Company does not have any change-in-control agreements or
arrangements in place for any of its NEOs, other than the general change in control provision as described in our 2007 Incentive
Stock Plan and our 2015 Incentive Plan as described later in this Annual Report.



Tax and Accounting Considerations



Tax Deductibility of Compensation Expense. Section 162(m)
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"), places a limit of $1,000,000 on the amount
of compensation to certain officers that may be deducted by the Company as a business expense in any tax year unless, among other
things, the compensation is performance-based and has been approved by the stockholders. To qualify as performance-based compensation,
the amount of compensation must depend on the officer's performance against pre-determined performance goals established by a committee
that consists solely of at least two "outside" directors who have never been employed by the Company or its subsidiaries.
It is the policy of the Compensation Committee to periodically evaluate the qualification of compensation for exclusion from the
$1 million deduction limit under Section 162(m) of the Internal Revenue Code while maintaining flexibility to take actions with
respect to compensation that it deems to be in the interest of the Company and its stockholders which may not qualify for tax deductibility.



So that the Compensation Committee may retain maximum flexibility
to structure performance targets based on corporate and individual metrics designed to achieve our various corporate goals, our
Cash Incentive Plan does not conform to the requirements of Section 162(m). However, stock option awards granted to our executive
officers have been structured so that the compensation realized when the stock options are exercised should be treated as performance-based
compensation exempt from the deduction limitation of Section 162(m). The Compensation Committee does not believe that any loss
of deductibility under Section 162(m) would have a material impact on the financial condition of the Company.



Tax Implications for Officers. Section 409A of the Internal
Revenue Code imposes additional income taxes on executive officers for certain types of deferred compensation that do not comply
with Section 409A. Because the Company does not provide deferred compensation to the NEOs, this limitation should not have an impact
on the structure of the compensation program for the officers. Section 280G of the Internal Revenue Code imposes an excise tax
on payments to executives of severance or change of control compensation that exceed the levels specified in Section 280G. The
NEOs could receive the amounts as explained in the section entitled "Potential Payments Upon Termination or Change in Control"
appearing later in this Annual Report as severance or change of control payments, but the Compensation Committee does not consider
their potential impact in compensation program design.



Accounting Considerations. The Compensation Committee
also considers the accounting and cash flow implications of various forms of executive compensation. In its financial statements,
the Company records salaries and performance-based compensation incentives as expenses in the amount paid, or to be paid, to the
NEOs. Accounting rules also require the Company to record an expense in its financial statements for equity awards, even though
equity awards are not paid as cash to employees. The accounting expense of equity awards to employees is calculated in accordance
with Financial Accounting Standards ("FASB") ASC Topic 718 (formerly known as SFAS 123(R)). The Compensation Committee
believes, however, that the many advantages of equity compensation, as discussed above, more than compensate for the non-cash accounting
expense associated with them.



Consideration of Compensation Programs and their Relationship
to the Encouragement of Risk-Taking



The Compensation Committee has reviewed all of the plans described
above, and does not believe that any of them encourage our NEOs to take unnecessary or excessive risks that threaten our value.
The features of these plans do not make it likely that taking



- 15 -






unnecessary or excessive risks that threaten our value will
provide greater compensation than actions that involve a prudent level of risk. The equity-based plans encourage our NEOs and other
employees to focus on increasing shareholder value over a period of years. The pension plans provide helpful ways for our employees
to save for retirement. The Compensation Committee believes that the plans described above do not pose any unnecessary risks, and
do not encourage employees to manipulate reported earnings to enhance the compensation of any employee.



COMPENSATION COMMITTEE REPORT



The Compensation Committee has reviewed and discussed the Compensation
Discussion and Analysis included in this Annual Report on Form 10-K with management.



Based on such review and discussions, the Compensation Committee
recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Annual Report on Form 10-K.

| | 1. | These columns consist of potential awards under our Cash Incentive Plan for fiscal year 2015. The Threshold column represents
the minimum amount payable when threshold performance goals are met. The Target column represents the amount payable if specified
performance targets are met. The Stretch column represents the amount payable if specified stretch performance goals are met. The
Maximum column represents the maximum amount payable under the Plan for 2015 based on the highest target levels. Amounts are based
on the executives' current salary as of the end of the Company's fiscal year. See the Summary Compensation Table for actual amounts
earned under the Cash Incentive Plan in fiscal year 2015 and the information provided earlier under the Compensation Discussion
and Analysis for a discussion of our Cash Incentive Plan. The Compensation Committee also included six-month performance goals,
that if achieved, could add an additional 20% to the above targets.

| | 5. | The grant date fair value of the option awards has been computed in accordance with FASB ASC Topic 718 (formerly known as SFAS
No. 123(R)), which requires that we recognize as compensation expense the value of all stock-based awards, including stock options,
granted to employees in exchange for services over the requisite service period, which is typically the vesting period, but excluding
forfeiture assumptions that are used in calculating equity award expense in the Company's financial statements. Refer to Note 19
to the Company's Consolidated Financial Statements on Form 10-K for the fiscal year ended September 30, 2015 for the relevant weighted-average
assumptions underlying the valuation of the option awards.

Potential Payments upon Termination or Change in Control



Effective March 12, 2015, our stockholders approved the Rofin-Sinar
Technologies Inc. 2015 Incentive Stock Plan ("the 2015 Incentive Plan"). The 2015 Incentive Plan supersedes the Rofin-Technologies
Inc. 1996 Non-Employee Directors' Stock Plan, the Rofin-Sinar Technologies Inc. 2002 Equity Incentive Plan and the Rofin-Sinar
Technologies Inc. 2007 Equity Incentive Plan. Under the above stock option plans, unless the Compensation Committee determines
otherwise in its sole discretion, if an employee's employment with the Company terminates by any reason other than death, disability,
or retirement, an employee has up to sixty days from the date of such termination or until the expiration of the stated term of
stock award, whichever period is shorter, to exercise any options that were exercisable on the date of such termination. If an
employee's employment with the Company terminates by reason of death, disability, or retirement, an employee has up to one year
from the date of such termination or, if earlier, until the expiration of the stated term of stock award, to exercise any options
that were exercisable on the date of such termination.



Upon any Change in Control, the Board shall have the right to
cancel all outstanding Options, Stock Appreciation Rights, Stock Grants and Stock Unit Grants after providing each Eligible Employee
and Director a reasonable period to exercise his or her Options and Stock Appreciation Rights and to take such other action as
necessary or appropriate to receive the stock subject to any stock grants or stock unit grants and the cash payable under any stock
unit grants.



Except as otherwise provided in the applicable award agreement,
and to the extent permitted under Section 409A of the Code, if an award granted under this Plan is assumed, continued, or replaced
by the Company or successor after the Change in Control, and if the holder's service with the Company or its successor is terminated
coincident with or within one year following the Change in Control either by the Company or its successor without Cause or by the
holder for Good Reason (as such terms are defined in the plan), then all conditions to the exercise of such holder's outstanding
Options and Stock Appreciation Rights on the date of termination and any and all outstanding issuance and forfeiture conditions
on any Stock Grants and Stock Unit Grants held by the holder on such date automatically shall be deemed 100% satisfied as of the
date of such termination of service.



The following constitute a change of control under the stock
plans:



| | • | any acquiring person becomes the beneficial owner of twenty percent (20%) or more of the then outstanding shares of Common
Stock;
| | - | ---------------------------------------------------------------------------------------------------------------------------------



| | • | the stockholders of the Company approve a merger or consolidation; or
| | - | ---------------------------------------------------------------------



| | • | the stockholders approve a plan of reorganization or complete liquidation of the Company
| | - | ----------------------------------------------------------------------------------------

In addition, in accordance with German law and their employment
agreements, each of Messrs. Merk and Hefter, and Ms. Mittelstaedt will, in the event they resign or are terminated by the Company,
be entitled to receive one-half of his or her monthly salary if the Company determines to enforce their six month non-competition
period. We would pay these amounts in equal monthly installments over six months.



The following table sets forth, for each of the following NEOs,
the potential amount that such NEO would realize upon the exercise of vested options held by the NEO as of September 30, 2015,
and the payments to which he or she would be entitled in connection with the non-compete clause in the relevant employment agreement,
assuming a termination or change in control as of September 30, 2015. The amounts shown are based on the difference between the
exercise price of the vested option and the closing price of the Common Stock on NASDAQ on September 30, 2015.

As noted above, effective July 1, 2015, Thomas Merk succeeded
Günther Braun as President and Chief Executive Officer. In connection with the succession, on June 4, 2015, the Company and
Mr. Braun entered into a Separation Agreement and General Release (the “U.S. Separation Agreement”) and ROFIN-SINAR
Laser GmbH and CBL Verwaltungsgesellschaft mbH, two of the Company’s indirect wholly-owned German subsidiaries, and Mr. Braun
entered into a Termination Agreement (the “German Termination Agreement”) in connection with Mr. Braun’s separation
from the Company and its subsidiaries.



Pursuant to the U.S. Separation Agreement, Mr. Braun ceased
to be an officer or director of the Company and its U.S. subsidiaries effective July 1, 2015, and he agreed to work with Mr. Merk
to facilitate a smooth and orderly transition process through June 30, 2015. The German Termination Agreement terminated Mr. Braun’s
existing employment agreement with his direct employer and provides that Mr. Braun will remain an employee and continue to receive
his existing base salary through September 30, 2017 (the “Termination Date”), which period of continued employment
and compensation is in accordance with the employment agreement that was terminated. The German Termination Agreement also provides
that Mr. Braun will receive a bonus for each of 2015, 2016 and 2017 in the amount of 25% of the base salary. The U.S. Separation
Agreement provides that Mr. Braun will remain eligible for continued vesting of previously awarded but unvested stock options in
accordance with the applicable plan documents through the Termination Date, whereupon any remaining unvested stock options will
become fully vested. Mr. Braun’s stock options will be exercisable through September 30, 2018. Both the U.S. Separation Agreement
and the German Termination Agreement contain certain non-competition and non-solicitation restrictive covenants and releases of
claims by Mr. Braun.

NON-EMPLOYEE DIRECTOR COMPENSATION



The Compensation program for non-employee directors is reviewed
annually by our Compensation Committee to ensure the program remains competitive. As part of the Compensation Committee's review,
the types and levels of compensation offered to our non-employee directors are compared with those provided by a select group of
comparable companies. Additionally, in January 2012, the Company hired Radford, a third party compensation consulting firm, to
assist with the analysis of the non-employee directors' compensation. The report has shown that the Company's average total non-employee
director compensation approximates the market's 25th percentile. The Compensation Committee strives to set compensation levels
that are competitive. The result of the report supports this goal.



Cash Compensation Paid to Board Members



Non-employee directors are entitled to receive an annual cash
retainer in the amount of $35,000 for service on the Board and attendance fees of $2,000 for each Board meeting ($1,000 for telephonic
meetings). Directors are also reimbursed for reasonable travel expenses incurred in connection with their duties as directors of
the Company.



In addition to the annual retainer, each non-employee director
who chairs the Audit, Compensation and Nominating Committees are entitled to an additional cash retainer in the amount of $10,000,
$7,000 and $4,000, respectively, for such service. The Lead Independent Director is also entitled to an additional cash retainer
in the amount of $12,000 for such service. Attendance fees are paid for Committee meetings as follows: $1,500 for each Audit Committee
meeting ($750 for telephonic meetings), $1,000 for each Compensation and Nominating Committee meeting ($500 for telephonic meetings);
and $1,500 for each other committee meeting ($750 for telephonic meetings), subject to review by the Board. Directors are also
reimbursed for reasonable travel expenses incurred in connection with their duties as members of the Committees.



Non-cash Compensation



The Company has reserved an additional 1,800,000 shares of Common
Stock under the 2015 Incentive Stock Plan approved at the Annual Meeting of Stockholders held on March 12, 2015, to provide for
the grant of options to purchase Common Stock ("options"), grants of shares of Common Stock ("stock grants"),
stock units, and stock appreciation rights ("SARs") to certain eligible employees and to non-employee directors. During
fiscal year 2015, outside directors each received 3,000 shares of Common Stock that were fully vested upon grant.



The following table shows the compensation paid in fiscal year
2015 to our non-employee directors. Directors who are also officers do not receive separate directors' fees and have been omitted
from this table if they appear in the Summary Compensation Table provided earlier in this Annual Report.

| | Item 13. | CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR
INDEPENDENCE
| | -------- | -------------------------------------------------------------------------



The main facility in Starnberg is rented
under a 25-year operating lease from the former minority shareholder of ROFIN-BAASEL Lasertech GmbH & Co. KG (“RBL”),
Mr. Baasel, who is also a member of the Board of Directors of the Company. That lease will terminate by end of December 2016. The
operating lease was acquired by the Company in 2000 as part of its then acquisition of RBL.  The Company paid expenses, mainly
for rental expense of approximately $735,000, $883,000 and $846,000 to Mr. Baasel during fiscal years 2015, 2014, and 2013, respectively.
In fiscal year 2015, the Company acquired a new manufacturing facility in Gilching, which is currently under reconstruction and
which is intended to replace all RBL leased facilities in Starnberg. As a result of the Company’s consolidation of operations
into a single facility, the required two-year notice of lease termination was given to Mr. Baasel in December 2014.



The Company believes that all transactions
noted above, have been executed on an arms-length basis. Except for the foregoing, no director, officer, nominee director, 5% holder
of the Company’s shares, or immediate family member, associate or affiliate thereof, had any material interest, direct or
indirect, in any transaction since the beginning of fiscal year 2015 or has any material interest, direct or indirect, in any proposed
transaction, having a value of $120,000 or more.



Director Independence



The information required by Item 407(a)
of Regulation S-K is incorporated herein by reference to Item 10 of this Annual Report “Directors, Executive Officers and

such services and these pre-approval decisions are presented to the full Audit Committee at its next scheduled meeting. During
fiscal year 2015 and 2014, the Audit Committee pre-approved 100% of the total fees to D&T.



During the two most recent fiscal years ended September 30,
2015 and 2014, and through December 1, 2015, there have been no reportable events (as defined in Regulation S-K, Item 304(a)(1)(v)).



The Company has not consulted D&T on any of the matters
referenced in Regulation S-K Item 304(a)(2) prior to D&T's appointment as the Company's independent registered public accounting
firm.
