In these cases, the broker can register your shares as being present at the meeting for purposes of determining the presence of a quorum but will not be able to vote on those matters for which specific authorization is required under the rules of the New York Stock Exchange (NYSE). If you are a beneficial owner whose shares are held of record by a broker, your broker has discretionary voting authority under NYSE rules to vote your shares on the proposal to ratify the selection of Ernst & Young LLP and the proposal to amend the Company's Certificate of Incorporation, even if the broker does not receive voting instructions from you. However, your broker does not have discretionary authority to vote on the election of Directorsdirectors or on the advisory vote on executive compensation without instructions from you, in which case a broker non-vote will occur and your shares will not be voted on these matters.

Your vote is important and we strongly encourage you to vote your shares by following the instructions provided on the voting instruction card.

Q:

What is "householding" and how does it work?

A:

The SEC's "householding" rules permit us to deliver only one set of proxy materials to stockholders who share an address unless otherwise requested. This procedure reduces printing and mailing costs. If you share an address with another stockholder and have received only one set of proxy materials, you may request a separate copy of these materials at no cost to you by writing to Cantel Medical Corp., 150 Clove Road, Little Falls, New Jersey 07424, Attn: Assistant Secretary, or by calling us at (973) 890-7220. Alternatively, if you are currently receiving multiple copies of the proxy materials at the same address and wish to receive a single copy in the future, you may contact us by calling or writing to us at the telephone number or address given above.

If you are a beneficial owner (i.e., your shares are held in the name of a bank, broker or other holder of record), the bank, broker or other holder of record may deliver only one copy of the notices of stockholder meetings and related proxy statements to stockholders who have the same address unless the bank, broker or other holder of record has received contrary instructions from one or more of the stockholders. If you wish to receive a separate copy of the notices of stockholder meetings and proxy statements, now or in the future, you may contact us at the address or telephone number above and we will promptly deliver a separate copy. Beneficial owners sharing an address, who are currently receiving multiple copies of the notice of stockholders meetings and proxy statements and wish to receive a single copy in the future, should contact their bank, broker or other holder of record to request that only a single copy be delivered to all stockholders at the shared address in the future.

The ten nominees include seven independent directors as defined in the NYSE rules and regulations.

        A majority of the votes cast is required for the election of directors in an uncontested election (which is the case for the election of directors at the meeting). A majority of the votes cast means that the number of votes cast "for" a director nominee must exceed the number of votes cast "against" that nominee. Our Corporate Governance Guidelines contain detailed procedures to be followed in the event that one or more directors do not receive a majority of the votes cast. Each nominee elected as a director will continue in office until the next Annual Meeting of Stockholders or until his or her successor has been elected or appointed.appointed and qualified, or until his or her earlier death, resignation or retirement.

BOARD MATTERS; COMMITTEES

Board Meetings and Attendance of Directors

        The Board held four regular meetings during the fiscal year ended July 31, 2012.2014. During fiscal 2012,2014, each of the directors attended 75% or more of the combined total meetings of the Board and the respective committees on which he served. Directors are required to make every reasonable effort to

attend the Annual Meeting of Stockholders. AllNine of the ten individuals then serving as members of the Board attended our last Annual Meeting of Stockholders.

Director Independence

        In determining independence pursuant to NYSE standards, each year the Board affirmatively determines whether directors have a direct or indirect material relationship with the Company that may interfere with their ability to exercise their independence from the Company. When assessing the materiality of a director's relationship with the Company, the Board considers all relevant facts and circumstances, not merely from the director's standpoint, but from that of the persons or organizations with which the director has an affiliation. Material relationships can include commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships. The Board has affirmatively determined that the following seven directors have no material relationship with us and are independent within the meaning of Rule 10A-3 of the Securities Exchange Act of 1934 (the Exchange Act) and within the NYSE definition of "independence": Alan R. Batkin, Ann E. Berman, Joseph M. Cohen, George L. Fotiades, Alan J. Hirschfield, Peter J. Pronovost, M.D., Ph.D. and Bruce Slovin. Our Board has also concluded that none of these directors possessed the objective relationships set forth in the NYSE listing standards

that prevent independence. None of our independent directors has any relationship with the Company other than his or her service as a director and on committees of the Board. Independent directors receive no compensation from us for service on the Board or the Committees other than directors' fees and equity grants under our 2006 Equity Incentive Plan.

Executive Sessions; Presiding Director

        As required by the NYSE listing standards, our non-management directors meet in executive sessions at which only non-management directors are present on a periodic basis.basis, generally following meetings of the full board of directors.

During the fiscal year ended July 31, 2012,2014, none of our executive officers served as a member of the board of directors or compensation committee of any entity that has one or more executive officers who serve on our Board or our Compensation Committee.

        Nominating Committee.    The Nominating Committee is composed of Mr. Fotiades (Chairman), Dr. Pronovost and Mr. Cohen. The Committee performs the following functions: (1) identifying individuals qualified to become Board members, consistent with criteria approved by the Board and recommending that the Board select the director nominees for the next Annual Meeting of Stockholders; (2) developing and recommending to the Board the Corporate Governance Guidelines; (3) overseeing evaluation of the Board and management and (4) reviewing and assessing the compensation paid to members of the Board and its committees. The Nominating Committee held one meeting during fiscal 2012.2014.

Board Leadership Structure

        The CEO and Chairman roles at Cantel are separated between Andrew A. Krakauer and Charles M. Diker, respectively, in recognition of their differing responsibilities. The CEO is responsible for leading the organization's day-to-day performance, executing the Company's strategies and ensuring the success of our acquisition program. The Chairman is responsible for advising the CEO, collaborating on acquisitions, and presiding over meetings of the Board. In addition, the Chairman is principally responsible for setting the strategic direction of the Company with assistance from the CEO. Although we do not have a formal policy regarding whether the offices of Chairman and CEO should be separate, our Board believes that the existing leadership structure, with the separation of the

Chairman of the Board and CEO roles, enhances the accountability of the CEO to the Board and strengthens the Board's independence from management. In addition, the Board believes that having a separate Chairman creates an environment that is more conducive to the objective evaluation and oversight of management's performance, increasing management accountability, and improving the ability of the Board to monitor whether management's actions are in the best interests of the Company and our stockholders.

Board Role in Risk Oversight

        The Board is responsible for oversight of the Company's management of enterprise risks. Cantel's senior management is responsible for the Company's risk management process and the day-to-day supervision and mitigation of enterprise risks. Management of the Company advises the Board on areas of material Company risk, including strategic, operational, financial, legal and regulatory risks. We do not believe our Board's oversight of risk influences our leadership structure, though we believe our leadership structure helps mitigate risk by separating oversight of our day-to-day business from the oversight of our Board.

Selection of Nominees for Election to the Board

        The Nominating Committee has established a process for identifying and evaluating nominees for director. Although the Nominating Committee will consider nominees recommended by stockholders, the Nominating Committee believes that the process it utilizes to identify and evaluate nominees for director is designed to produce nominees that possess the educational, professional, business and personal attributes that are best suited to further our purposes. Any interested person may recommend a nominee by submitting the nomination, together with appropriate biographical information, to the Nominating Committee, c/o Cantel Medical Corp., 150 Clove Road, Little Falls, NJ 07424, Attn: Assistant Secretary. All recommended candidates will be considered using the criteria set forth in our Corporate Governance Guidelines.

        The Nominating Committee will consider, among other things, the following factors to evaluate recommended nominees: the Board's current composition, including expertise, diversity, balance of management and non-management directors, independence and other qualifications required or recommended by applicable laws, rules and regulations (including NYSE requirements) and company policies or procedures. Although the Board considers diversity as a factor to be considered in identifying and evaluating nominees, it does not have any formal policy with respect to diversity. The Nominating Committee will also consider the general qualifications of potential nominees, including, but not limited to personal integrity; concern for Cantel's success and welfare; experience at strategy/policy setting level; high-level leadership experience in business or administrative activity; breadth of knowledge about issues affecting Cantel; an ability to work effectively with others; sufficient time to devote to the Company; and freedom from conflicts of interests.

COMPENSATION DISCUSSION AND ANALYSIS

        The Compensation Committee of our Board discharges certain responsibilities of the Board with respect to compensation of the Company's executive officers, which, for the fiscal year ended July 31, 2012,2014, included our Chairman of the Board and member of Office of the Chairman, Charles M. Diker; President/Chief Executive Officer (CEO) and member of Office of the Chairman, Andrew A. Krakauer; SeniorPresident and Chief Operating Officer and member of Office of the Chairman, Jorgen B. Hansen; Executive Vice President, General Counsel and Secretary, Eric W. Nodiff; Seniorand Executive Vice President, Chief Financial Officer (CFO) and Treasurer, Craig A. Sheldon; and Vice President and Controller, Steven C. AnayaSheldon (collectively, the Named Executive Officers or NEOs).

Objectives of Compensation Programs

        The primary objectives of the Company's compensation program are to:

•

Closely align the interests of the executive officers with those of the stockholders, and



•

Offer compensation opportunities that attract and retain talented executive officers, motivate such officers to perform at their highest level and reward their achievements.

        The abilities and performance of the Company's executives are critical to the Company's long-term success, and the objectives of the compensation program are designed to complement each other by balancing the Company's interest in achieving both its short-term and long-term goals. Base salary and incentive-based cash bonuses are paid to reward performance and the achievement of short-term objectives and equity awards are used to align the executives' interests with the long-term success of the Company.

What the Company's Compensation Program is Designed to Reward

        The Company's business plan emphasizes growth through the expansion of existing operations and the addition of new products through acquisitions and product development. This strategy is advanced by identifying and acquiring businesses; effectively integrating acquired operations, personnel, products

and technologies into the organization; retaining and motivating key personnel throughout the Company; attracting and retaining customers; and encouraging new product development. In addition, the Company relies on its executives to sustain and efficiently manage current businesses while adapting and growing its business segments in response to the ever-changing competitive landscape, and, in general, to maximize stockholder value. The compensation program is designed to reward the NEOs for successfully managing these tasks, increasing earnings of the Company, and creating stockholder value.

Role of Peer Group CEO Compensation Consultant and Survey Data

        AlthoughWith respect to our CEO's compensation in fiscal 2014, in order to obtain a general understanding of current trends in compensation practices and ranges of amounts being awarded by other public companies to their chief executive officers, the CEO provided the Compensation Committee with a list of peer group companies to the Company that are public companies engaged in our industry, in related industries, or that possess size or other characteristics which are similar to ours. The Compensation Committee then provided this list to an independent consulting firm, The Kinsley Group, and such consulting firm provided the Compensation Committee with data requested by the Compensation Committee about the compensation paid by these companies to their chief executive officers. While the consulting firm assisted the Compensation Committee in compiling and interpreting such data, it did not otherwise provide advice to the Committee regarding compensation decisions. The Kinsley Group has not provided any services to management. Further, the Compensation Committee has retainedreviewed the nature of the relationship with The Kinsley Group and worked with an independent consulting firmdid not believe there were any conflicts of

interest that impacted the data provided to the Compensation Committee. The companies in the past, it electedpeer group consisted of: AngioDynamics, Inc., ICU Medical, Inc., Masimo Corporation, Medical Action Industries Inc., Merit Medical Systems Inc., Natus Medical Inc., NuVasive, Inc., Volcano Corporation and Wright Medical Group, Inc.

        The Compensation Committee used the peer group data principally to obtain a general understanding of median base salary, bonus and severance levels paid to chief executive officers in the healthcare industry and to determine where compensation levels of the Company's CEO fell relative to median compensation levels of comparable industry executives. The data showed that the combined base salaries and short-term cash incentives were mixed relative to the medians in the comparative groups. However, the Committee did not utilize the data for benchmarking to do sospecific market percentiles or modify any salaries, incentives or benefits of the CEO based on the data in the survey. The Committee took this data into account, as reference points to be considered in determining if its current levels and mix of compensation for fiscal 2012. In addition, itthe CEO were reasonable for the Company.

        The Compensation Committee did not utilize any specific survey data or benchmarking with respect to fiscal 2012 compensation.2014 compensation of any of the other NEOs. Instead, the Committee relied on its own analyses and processes described herein in setting fiscal 20122014 compensation for the NEOs. In the future,

Elements of the Compensation Program; Why the Compensation Committee Chose Each Element and How it Relates to the Company's Objectives

        The two principal elements comprising executive compensation are cash and equity awards. The cash element is divided into base salary and annual cash incentives under the Company's Annual Incentive Compensation Plan, which constitutes the short term incentive compensation plan (STIP) and the equity element consists of stock options and restricted stock awards (subject to a risk of forfeiture) under the Company's Long Term Incentive Compensation Plan (LTIP). These elements complement each other and give the Compensation Committee flexibility to create compensation packages that provide short and long-term incentives in line with the Company's approach to compensation. Such approach is designed to provide the executive sufficient cash to be competitive with other employment opportunities, while at the same time providing the executive with an incentive to build stockholder value by aligning the executive's interests with those of our stockholders.

        Base salary is the primary fixed element of the Company's compensation program and is used to attract and retain, as well as motivate and reward, executive officers. In determining the base salary of NEOs, the Compensation Committee considers the experience, skills, knowledge and responsibilities required of the executive officer in his role, specifically, the functional role of the position, the level of the individual's responsibility, the ability to replace the individual, and if applicable, the base salary of the individual at his prior employment.

        Short-term incentive compensation is an opportunity for executives to receive cash bonuses based on the Company's (or its divisions') annual financial performance. The short-term incentive compensation is intended to reward performance for the most recently completed fiscal year when financial objectives are achieved and motivate and retain qualified individuals who have the opportunity to influence future results, advance business objectives, and enhance stockholder value. Likewise, this element of compensation is designed to provide a reduced award or no award when financial objectives are not achieved. Under the STIP, target amounts for the annual bonus opportunity are required to be established within 75 days after the commencement of the fiscal year and are based on achievement of one or more metrics described in the STIP. The exact annual metrics and targets to be used under the STIP are approved by the Compensation Committee each year. In addition, under the STIP, the

Compensation Committee has the flexibility to award additional discretionary bonuses to recognize and reward performance in excess of measurable performance objectives.

        Although Mr. Diker does not participate in the STIP, during fiscal 2014 the Compensation Committee made Mr. Diker eligible to receive a separate target bonus of $75,000 (for the last six months of fiscal 2014) plus a discretionary bonus determined by the Compensation Committee. Both the target bonus and does not receive cash bonuses.discretionary bonus were based on the same Company annual financial performance objectives imposed on executives under the STIP for fiscal 2014. The Committee decided to provide bonus eligibility to Mr. Diker to reward him on the same basis as other executives when financial objectives of the Company are achieved. Although Mr. Diker received his target bonus, he waived his entitlement to the discretionary bonus.

        For fiscal 2012,2014, the Committee established a target level, as a percentage of base salary, for each member of senior management for purposes of determining cash bonuses under the STIP. Achievement of the target levels was based on attainment of the Company's fiscal 20122014 targeted diluted earnings per share (EPS) and, in the case of division CEOs, budgeted operating income for the applicable division. Factors included in the process of determining senior management target levels, as well as discretionary additional bonuses, were business performance, scope of responsibilities and accountability, competitive and other industry compensation data, special circumstances and expertise, individual performance, comparison with compensation of our other senior managers and recommendations of the Chairman of the Board and the CEO.

        The purpose of the LTIP is to contribute to the motivation of key employees in accomplishing the Company's long-term strategic and stockholder value goals. Through equity awards, the LTIP is designed to communicate and reinforce strategic, operational and financial objectives linked to creating stockholder value, provide a competitive incentive for achievement of long-term corporate stockholder value goals and establish an objective basis for determining annual long-term incentive awards for eligible participants.

        Equity awards (which may consist of restricted stock, stock options, stock appreciation rights or performance awards) are granted under the LTIP to NEOs in order to give them an ownership interest in the Company, thereby aligning their interests with those of the stockholders and providing a long-term incentive. Restricted stock awards consist of awards of the Company's common stock subject to specified vesting restrictions or conditions including, among other things, continued employment with the Company. Stock options and stock appreciation rights (rights to receive a payment equal to the increase in fair market value of the Company's common stock since the grant date thereof) are equity awards whose value depends on an increase in the Company's common stock price. The Compensation Committee determined at the end of fiscal 2010 to no longer grant stock options to management under the LTIP and rather, to grant only restricted stock to management. Grants of restricted stock have intrinsic value regardless of price appreciation, and may create a better identity of interests between management and other stockholders. In addition, the Committee believes that due to their intrinsic value, restricted shares may have a stronger retentive effect on management than stock options. Following fiscal 20122014, restricted stock awards were granted to management under the LTIP. Mr. Diker does not participate in the LTIP but is awarded restricted stock awards and stock options as an employee of the Company from time to time based on recommendations of the Compensation Committee and approval of the Board.

        The Compensation Committee typically imposes time-based vesting conditions on stock options and restricted stock awards because it believes that time based vesting encourages recipients of awards to remain employed by the Company and continue to provide services to us, and also encourages recipients to build stockholder value over a long period of time. As with other issued shares of our common stock, recipients of restricted stock (but not stock options) awarded under the LTIP are entitled to receive dividends we pay on our common stock.

Risk in Our NEO Compensation Program

        Our Compensation Committee believes that the mix and design of the elements of executive compensation do not encourage management to assume excessive risks. We believe the base salary levels of our executives mitigate excessive risk-taking behavior by providing reasonable predictability in the level of income earned by each executive and alleviating pressure on executives to focus exclusively on stock price performance to the detriment of other important business metrics. We also provide a mixture of both short-term and long-term incentives. With a significant weighting on long-term incentives that are subject to time-based vesting, we believe NEOs' incentives are aligned with those of our stockholders and short-term risk taking is discouraged. In addition, the performance measures used for short-term incentives are intended to be challenging yet attainable, so that it is more likely than not

that the executives will earn a substantial portion of their target bonus annually, which mitigates the potential that our executives will take excessive risks. The metrics we use are typically calculable in accordance with generally accepted accounting principles (GAAP) and audited at the end of the year. Also, for fiscal 2014, short-term incentives in the form of annual performance bonus payouts have been established, depending on an executive's position, at between 40-85%40-100% of base salary for on-target performance. Under the STIP, the Compensation Committee may determine that extraordinary performance warrants a higher payout but with a cap of 200% of targeted bonus, which the Compensation Committee believes mitigates the likelihood that our executives will take excessive risks. In addition, stock options and restricted stock awards granted to employees generally vest annually over three years, so executives always have a significant amount of unvested awards that could decrease significantly in value if our business is not managed for the long-term. The Compensation Committee further retains discretion under both the STIP and LTIP to reduce or not pay awards under such plans due to an NEO's misconduct or poor performance.

How the Compensation Committee Chose Amounts and Formulas for Each Element

        Base Salary.    Currently the Compensation Committee approves the base salaries of all NEOs; however, the base salary of Mr. Diker, who provides services to the Company on a part time basis, is also subject to approval by the Board. InOn February 2012,1, 2014, the base salary of the Chairman was increased by 17%, from $300,000 to $350,000 and the base salary of the CEO was increased by 8.3%13%, from $485,000$575,000 to $525,000$650,000, both in recognition of histheir contributions and the performance of the Company. The base salary of eachsalaries of Messrs. Anaya,Hansen, Nodiff and Sheldon waswere increased by 5.0%3.0% in recognition of their contributions and the performance of the Company. The Committee maintained the relative differences among them (other than the Chairman and CEO) that had been established in prior fiscal years based on the NEOs' roles and responsibilities and the Committee's prior perception of executives of other similar companies of similar position, responsibility, experience, qualifications, and performance. The greater percentage increase for the Chairman was based on the Committee's desire to more closely align his salary with other executive officers of the Company. The greater percentage increase for the CEO was due to his leadership of the Company expanded responsibilities with theand continued growth of the Companysales and the excellent fiscal 2011 operating resultsearnings. The current base salaries of the Company. The base salary of Mr. Diker, who does not provide services to the Company on a full time basis, was established by the Board in recognition of his contributions to the Company. Mr. Diker's base salary of $250,000 was not changed during fiscal 2012. The base salary of the NEOs which will remain in effect through at least January 31, 2013, are as follows:

        Short-Term Incentive Plan.    For fiscal 2012,2014, the Compensation Committee chose EPS as the performance metric under the STIP, as well as for the target bonus compensation payable to Mr. Diker, to maintain a focus on increasing stockholder value and driving superior financial performance. The

Committee believes EPS is a key metric in measuring the Company's success and provides certainty and comparability since it is calculated in accordance with generally accepted accounting principles and audited each year. Specifically, for fiscal 20122014 the performance target was diluted EPS of $0.96.$1.03.

        For fiscal 2012,2014, the target incentive awards under the STIP, established as a percentage of base salary (and as a fixed dollar amount in the case of Mr. Diker), were set by the Compensation Committee as follows:

        The target incentive award percentages of Messrs. Krakauer and Hansen under the STIP were increased following fiscal 2013 from 85% to 100% for Mr. Krakauer was increasedand from 60% to 70% to 85% andfor Mr. Hansen based on their individual performances as well as the target incentive awards for Messrs. Nodiff and Sheldon were each increased by 5% fromCompany's fiscal 2011. The increases were made in consideration of the continued growth and positive performance of the Company and the increased responsibilities of the NEOs.2013 performance.

        In fiscal 2012,2014, the Company exceeded the diluted EPS performance target of $0.96$1.03 compared to our actual diluted EPS of $1.15.$1.04. Therefore, Messrs. Diker, Krakauer, Hansen, Nodiff Sheldon and AnayaSheldon each received his full target incentive award. In addition, because of the significant extent by which our actual EPS exceeded our performance target and our prior year's diluted EPS the surpassing of other financial targets such as cash flow and EBITDAS,$0.95 as well as the closing and successful integration of our most recent acquisitions, the Compensation Committee utilized its discretion under the STIP to award additional cash bonuses to our NEOs (exclusive ofNEOs. Mr. Diker who does not participatevoluntarily waived his participation in our STIP)discretionary bonus compensation for fiscal 2014. The discretionary STIP awards increased the incentive-based awards by 25%. Total STIP awards to NEOs for fiscal 20122014 were as follows:

        These discretionary STIP awards increased the incentive-based awards by 90%. The percentage of the fiscal 2012 discretionary awards was increased relative to the fiscal 2011 awards due to the Compensation Committee's assessment of the Company's performance during fiscal 2012 relative to fiscal 2011.

        Equity Awards.    The Compensation Committee determines the number of shares of stock underlying the equity awards based upon each NEO's position and performance during the fiscal year. The Committee established fiscal 20122014 equity award targets for all NEOs other than Mr.Messrs. Diker and Krakauer based on a percentage of their base salary (described below). Mr. Diker is not a participant in the LTIP but has received equity awards from time to time upon the recommendation of the Compensation Committee and approval of the Board. All restricted stock awards to NEOs are subject to vesting in three equal annual installments beginning on the first anniversary of the grant date.

        The target incentive equity award percentages and fixed value award (in the case of Mr. Krakauer) were determined by the Compensation Committee to reflect the objectives of the LTIP and to give effect to the positions, responsibilities and contributions to the Company of each NEO. The percentages also reflect the Compensation Committee's view, based on past analyses which were not updated in fiscal 2012,2014, of market-based differences for similarly positioned executives at other companies.

        On October 15, 2012,10, 2014, the Compensation Committee awarded the NEOs restricted shares under the LTIP attributable to fiscal 20122014 performance based on the $25.56$36.08 closing price of Cantel common stock on the NYSE on thatthe date immediately preceding the grant date. In addition, the Compensation Committee awarded Mr. Diker a stock option to purchase 35,00025,000 shares at an exercise price of $36.70, the closing price of Cantel stock on the NYSE on the date of grant, based on his contributions to the Company and for providing direction and assistance to management during fiscal 2012.2014.

        Mr. Krakauer was awarded 39,12541,575 shares of restricted stock, calculated by dividing $1,000,000$1,500,000 by $25.56.$36.08, the closing price of Cantel stock on the NYSE on the date immediately preceding the grant date. This represented a significant$250,000 increase in value from the prior year's restricted stock award to Mr. Krakauer. Following fiscal 2011, Mr. Krakauer was awarded 35,812 shares, which was calculated by dividing $485,000 by $13.54 (the closing price of Cantel common stock on the NYSE on the date of grant). The increase was in recognition of the Company's significantoverall growth since Mr. Krakauer became President and subsequently, CEO of the Company, as well as the Compensation Committee's perception of CEO compensation of other similar companies of similar position, responsibility, experience, qualifications, and performance.

        The number of shares of restricted stock issued to Messrs. Nodiff and SheldonMr. Hansen was calculated by (1) multiplying such NEO'shis base salary by the100% (his incentive award percentagepercentage) and (2) dividing the product by $25.56.$36.08.

        The number of shares of restricted stock issued to Mr. AnayaNodiff was calculated by (1) multiplying 50%his base salary by 85% (his incentive award percentage) and (2) dividing the product by $36.08. Due to Mr. Sheldon's announced plans for retirement and as part of the agreement reached between the Company and Mr. Sheldon on severance payable in connection with his retirement, Mr. Sheldon did not receive a grant of restricted stock award. There was no change in the formulas from the priorshares with respect to fiscal year.2014.

        For the awards to Mr. Diker and the NEOs, the Compensation Committee established the following payment percentages and, as a result, made the grants indicated:

Post-Retirement and Other Benefits

        Each of Messrs. Krakauer, Nodiff, SheldonHansen and AnayaNodiff is party to a severance agreement with the Company that contains certain post-termination benefits. Mr. Sheldon has announced his future retirement and has entered into a retirement agreement with the Company described below that, together with other agreements referenced therein that take effect upon retirement, will govern the benefits related to his retirement. The compensation payable to Mr. Sheldon under the retirement agreements recognizes his long service to the Company, the desire to ensure a smooth transition of duties to his successor, and the desire to secure Mr. Sheldon's consulting services following retirement.

        The Compensation Committee believes that post-termination benefits are an important aspect of an executive compensation program because they allow the Company to better recruit and retain executive officers by offering competitive compensation packages. Such benefits also allow the executive officers to focus on performance of their duties and eliminate distractions related to job security concerns. The severance agreements also provide benefits in the event of a change in control of the Company to further align the interests of the executive with those of the stockholders. These arrangements are primarily intended to maintain the executive's motivation to consummate the sale of the Company in circumstances where such event will maximize stockholder value, notwithstanding that such transaction may result in the executive's loss of continued employment with the Company. We

believe a "double trigger" requiring actual termination following a change of control rather than simply awarding amounts in the event of a change of control best aligns the NEOs' interests by encouraging them to continue to perform their duties adequately rather than simply receiving an award for completing a transaction.

        We believe that these severance benefits are reasonable and appropriate for our NEOs in light of the anticipated time it takes high-level executives to secure new positions with responsibilities and

compensation that are commensurate with their experience. We do not include "gross-up" provisions in the severance agreements. A more detailed description of our severance agreements may be found below under the heading "Post Termination Benefits and Change in Control."

        Severance benefits also include the vesting of 100% of the executives' unvested stock options and unvested restricted stock awards and other similar rights in certain circumstances. We believe that the equity awards granted to our executive officers have been reasonable in amount and that, in the event of a change in control and certain other terminations, it is appropriate that our executive officers receive the full benefit under their equity compensation awards of the increase in Cantel's value attributable to the performance of the current management team.

        The severance agreements for our NEOs (other than Mr. Sheldon, whose benefits are now governed by the retirement agreements described below) provide equal benefits for each NEO that is a party to a severance agreement, other than with respect to cash severance payable in the event of a termination in a non-change of control situation (i.e., a termination without cause). In such event, the CEO (i.e., Mr. Krakauer)Krakauer (CEO) is entitled to two times the sum of the CEO'shis base salary and target bonus at the time of termination; a 15-year executive (e.g., Mr. Sheldon)Hansen (COO) is entitled to 18 months' base salary; and the other executives (i.e., Messrs.Mr. Nodiff and Anaya) areis entitled to 12 months' base salary. During fiscal 2012, the CEO was entitled to 18 months' base salary in this scenario. The Compensation Committee increased such amount on October 31, 2012 to (a) 24 months' base salary plus (b) two times Mr. Krakauer's annual target bonus based on the rate in effect as of the relevant termination date (currently 85% of his annual base salary). The change was made based on the Committee's perception of severance being paid to executives of other similar companies of similar position, responsibility, experience, qualifications, and performance. We believe that a higher severance formula for our CEO is justified and needed in order to attract the individual we believe is best suited for the office. Our CEO is the individual the public and our stockholders most closely identify as the face of the company. He has the greatest individual impact on our success, and he faces the greatest personal risks when the company takes risks. We also believe that the position of Chief Operating Officer merits a higher severance formula in order to attract the individual we believe is best suited for the office. Finally, we believe that any NEO (other than Mr. Diker) who has 15 years of employment with the Company should be entitled to additional compensation in the event of a termination of his employment in a non-change in control situation in recognition of his long service to the Company.

        In addition to the above benefits, we provide to Messrs. Krakauer, Hansen, Nodiff Sheldon and AnayaSheldon (1) term life insurance equal to one year's base salary, (2) a car allowance equal to $750 a month plus related expenses, (3) an executive physical once every three years (up to $3,500, subject to a gross-up to make this benefit tax neutral), (4) a $7,000 allowance for disability insurance or long term care insurance and (5) a 401(k) plan match. We believe these perquisites and benefits are appropriate as part of a competitive benefits package. Mr. Diker is provided a 401(k) plan match.

Say-on-Pay Vote Response

        In evaluating our compensation process for fiscal 2012,2014, our Compensation Committee generally considered the results of the advisory vote of our stockholders on the compensation of the executive officers named in our last proxy statement related to our prior annual meeting of stockholders. Our Compensation Committee noted that more than 97% of votes cast approved of the compensation of those executive officers as described in our last proxy statement. Our Compensation Committee considered these voting results as supportive of the Compensation Committee's general executive compensation practices.

Tax Deductibility of Compensation

        Section 162(m) of the Internal Revenue Code (the Code) limits the deduction a public company is permitted for compensation paid to the chief executive officer and to the four most highly compensated executive officers other than the chief executive officer. Generally, amounts paid in excess of $1,000,000

to a covered executive cannot be deducted, unless the compensation is paid pursuant to a plan which is performance related, non-discretionary and has been approved by stockholders. In its deliberations the Compensation Committee considers ways to maximize deductibility of executive compensation, but nonetheless retains the discretion to compensate executive officers at levels the Committee considers commensurate with their responsibilities and achievements. We have not adopted a policy that all executive compensation be fully deductible. A portion of Mr. Krakauer's compensation is non-deductible. The compensation of all other NEO's is fully deductible.

        The following table sets forth certain additional information regarding grants of plan-based awards to our Named Executive Officers for the fiscal year ended July 31, 2012:2014:

Narrative Addendum to the Summary Compensation Table and Grants of Plan-Based Awards Table

Short-Term Incentive Plan

        Under the STIP, our NEOs (other than Mr. Diker) and certain other executives and key employees of the Company are eligible to receive cash bonus awards based on their achievement of performance targets for each fiscal year ending July 31st (each year being referred to as a Plan Year).

        The STIP is administered by the Compensation Committee, which establishes annual performance targets (the Performance Targets) for each Plan Year. Awards are based on the achievement of the Performance Targets, which are based on the attainment of specified levels of one or any combination of the following: revenues, cost reductions, operating income, income before taxes, net income, adjusted net income, earnings per share, adjusted earnings per share, operating margins, working capital measures, return on assets, return on equity, return on invested capital, cash flow measures, market share, stockholder return or economic value added of the Company or the subsidiary or division of the Company for or within which the participant is primarily employed. Such Performance Targets may also be based on the achievement of specified levels of Company performance (or performance of an applicable subsidiary) under one or more of the measures described above relative to the performance of other corporations. For fiscal 2012,2014, the Compensation Committee utilizedestablished a Performance Target of EPS of $1.03, which was $0.03 higher than the Company's fiscal 20122014 budgeted EPS of $0.96.$1.00. In fiscal 2012,2014, the Company exceeded this Performance Target.

        The target incentive awards for each eligible position (by category) are expressed as a percentage of base salary within the ranges designated below for fiscal 2014 (with the actual target incentive award percentages determined by the Compensation Committee on an annual basis):

        For fiscal 2012,2014, the actual target incentive awards were set by the Compensation Committee as follows:

        Notwithstanding the foregoing, Division CEOs have 25% of their bonus target based on the annual Performance Target established for executives of Cantel. The remaining 75% is based on the annual performance target specific to the operations of such CEO's Division(s), which are established by the CEO of the Company in consultation with the Compensation Committee.

        Awards are determined as follows:

        For fiscal 2012,2014, none of the Division CEOs were NEOs.

        The target incentive award payable to each participant for 100% achievement of the Performance Targets (the Bonus Target) is calculated by multiplying the participant's base salary earned duringat the end of the relevant Plan Year by a designated percentage established by the Compensation Committee for such participant for such Plan Year.Year (pro rated if an NEO was employed for a partial year). If more or less than 100% of the Performance Target is achieved, the Compensation Committee has the discretion to increase the Bonus Target (not to exceed 200% of the Bonus Target) or decrease the Bonus Target (not to be less than 50% of the Bonus Target, provided that a minimum threshold performance level has been achieved); provided, however, that the Compensation Committee in its discretion may establish minimum Performance Targets that must be achieved in order for any incentive award to be paid. The Compensation Committee will determine the degree to which any applicable Performance Target has been achieved and any incentive award paid. At the sole discretion of the Compensation Committee, a participant may not receive an award, or the amount of an award may be decreased, due to substantiated poor individual performance or misconduct and may be declared ineligible under the STIP.

        For fiscal 2012,2014, the Compensation Committee established the following payment criteria based on the achievement of the Performance Target:

        The actual awards for our NEOs under the STIP for fiscal 20122014 are shown in the tables and discussed in Compensation Discussion and Analysis above.

Long-Term Incentive Plan

        The purpose of the LTIP is to contribute to the motivation of key employees in accomplishing the Company's long-term strategic and stockholder value goals. All equity awards under the LTIP are granted under the Company's 2006 Equity Incentive Plan (the Plan), which is described below, and are subject to the terms thereof.

        Under the LTIP, NEOs (other than Mr. Diker) and other executives and certain key employees of the Company, are eligible to receive annual equity awards for each Plan Year. Participants are identified by title and recommended by the CEO of the Company each year, subject to the approval of the Compensation Committee. The Compensation Committee administers the LTIP with respect to all participants. The annualized expected value of the participants' target awards under the LTIP are reviewed annually by the Compensation Committee. Except asAs described above, with respect to the CEO, the Compensation Committee did not modifyincreased the annualized expected value of the participants'Mr. Krakauer's target awards under the LTIP for fiscal 20122014 from the prior year.

        Performance based awards under the LTIP are contingent on acceptable individual performance as well as predetermined financial objectives of the Company or one or more of its subsidiaries or operating segments determined by the Compensation Committee. Performance based awards vest upon achievement of the designated performance criteria, which will be based on the attainment of specified levels of one or any combination of the following: revenues, cost reductions, operating income, income before taxes, net income, adjusted net income, earnings per share, adjusted earnings per share, operating margins, working capital measures, return on assets, return on equity, return on invested capital, cash flow measures, market share, stockholder return or economic value added of the Company or the subsidiary or division of the Company for or within which the participant is primarily employed. Such performance goals also may be based on the achievement of specified levels of Company performance (or performance of an applicable subsidiary) under one or more of the measures described above relative to the performance of other corporations. Notwithstanding the specific performance criteria established, in making a determination as to whether or not such criteria such as earnings growth was achieved, the Compensation Committee takes into consideration factors such as unanticipated taxes, acquisition costs, non-recurring and extraordinary items (if any), and other equitable factors, as determined by the Compensation Committee in its discretion. If a participant's employment with the Company is terminated for any reason, the participant will forfeit any non-vested performance based awards. The Compensation Committee did not grant any performance based awards in fiscal 2012.2014.

        Service-based awards under the LTIP vest ratably over three years following the date of grant, or such other period of time determined by the Compensation Committee, subject to the terms and conditions set forth in the Plan and the agreement reflecting the award. Under the LTIP, in the event a participant's employment is terminated prior to the end of the vesting period due to (A) death, all of the service-based awards granted to the participant under the LTIP will automatically vest as of the date of termination of employment, (B) Retirement (as defined in the LTIP), all of the service-based

stock options granted to the participant under the LTIP will automatically vest and the participant will forfeit any non-vested restricted stock awards or portions thereof granted under the LTIP unless the Compensation Committee, in its discretion, accelerates the vesting of such non-vested restricted stock awards, or (C) disability, any service-based awards that would have vested within the 12 month period following the termination date but for the participant's termination of employment (e.g., stock options and restricted stock awards subject only to time vesting) will automatically vest as of the termination date.

        At the sole discretion of the Compensation Committee, a participant may not receive an award or may receive a reduced award due to substantiated poor individual performance or misconduct and may be declared ineligible under the Plan.

        The actual awards for our NEOs under the LTIP for fiscal 20122014 are shown in the tables and discussed in Compensation Discussion and Analysis above.

2006 Equity Incentive Plan

        The Plan provides for the granting of stock options, restricted stock awards, stock appreciation rights (SARs) and performance awards to our employees, including our executive officers. Non-employee directors also participate in the Plan. The Plan does not permit the granting of discounted options or discounted SARs. The selection of employee participants in the Plan and the level of participation of each participant are determined by the Compensation Committee (the Board makes determinations relating to awards to directors). The number of shares that may be granted to a participant under the Plan during any calendar year may not exceed 75,000.168,750. Subject to the limitations set forth in the Plan, the Compensation Committee may delegate to our Chief Executive Officer or other executive officers such duties and powers as the Compensation Committee may deem advisable with respect to the designation of employees to be recipients of Plan awards and the nature and size of such awards, except that no delegation may be made in the case of awards to executive officers or directors or awards intended to qualify under Section 162(m) of the Code, or individual awards in excess of 1,5003,375 restricted shares or 5,00011,250 stock options (or aggregate awards during any fiscal quarter in excess of 5,00011,250 restricted shares or 25,00056,250 stock options) or such other parameters as may be set forth by the Compensation Committee in a subsequent resolution.

        The Plan permits the grant of non-qualified stock options, incentive stock options qualifying under Section 422 of the Code (ISOs) and SARs. SARs permit the recipient to receive a payment measured by the increase in the fair market value of a specified number of our shares from the date of grant to the date of exercise. Distributions to the recipient of a SAR may be made in common stock, in cash, other property or in any combination of the preceding as determined by the Compensation Committee. The Compensation Committee determines the terms of each stock option and SAR at the time of the grant. The exercise price of a stock option may not be less than the fair market value of our common stock on the date the option is granted; likewise, no SAR may be granted at less than the fair market value of our common stock on the date the SAR is granted. The Compensation Committee determines the exercise period of each stock option and SAR; however, the terms of stock options and SARs granted under the Plan may not exceed ten years. The Compensation Committee did not award any SARs in fiscal 2014.

        Unless otherwise provided by the Compensation Committee, in the event of the termination of a participant's service as an employee or non-employee director for any reason other than the participant's Retirement (as defined in the Plan), death or disability, stock options and SARs (to the extent exercisable) will remain exercisable for a period of 90 days from such date or until the expiration of the stated term of such stock options or SARs, whichever period is shorter (except that in the case of a termination of employment for cause, such stock options and SARs will immediately expire). Unless otherwise provided by the Compensation Committee, upon the termination of a participant's

employment due to death or disability, stock options and SARs granted to such participant will remain exercisable (to the extent vested) for a period of one year from such date or until the expiration of the stated term of such stock options or SARs, whichever period is shorter. In addition, when an employee or non-employee director who has at least ten years of service with the Company and is at least 65 years of age (or at least 60 years of age with at least fifteen years of service) terminates his or her service as an employee or director (i.e., Retires), all stock options and SARs granted to such employee or director under the Plan will, upon such termination, become immediately exercisable in full and remain exercisable through the original term of the award.

        Generally, no stock option granted under the Plan may be exercised during the first year of its term or such longer period as may be specified in the option grant. However, the Plan gives the Compensation Committee the authority, in its discretion, to accelerate the vesting of stock options. The Plan also provides that unvested stock options and SARs will immediately vest if the recipient's

employment or service with the Company is terminated as a result of the recipient's death or Retirement, or is terminated without cause during the 12-month period following a change in control. The Plan similarly provides for the acceleration of vesting of the next tranche of stock options and SARs in the event of a termination of employment or service as a result of disability. The Plan also provides for the acceleration of vesting of a stock option or SAR if such accelerated vesting is provided under any benefit plan of the Company to which the recipient is subject. In addition, under the Plan, the Compensation Committee may in its discretion "cash out" any award, whether vested or unvested, upon a change in control by paying the recipient the amount by which the Change in Control Price (as defined in the Plan) exceeds the exercise or grant price per share under the stock option or SAR award multiplied by the number of shares granted under the stock option or SAR award. The Plan does not permit the repricing of options or the exchange of underwater options for cash or other awards without shareholder approval.

        Under the Plan, the Compensation Committee may also grant restricted stock awards and performance awards, subject to specified restrictions or vesting conditions, including but not limited to continued employment or service of the recipient with us (in the case of restricted stock awards) or the achievement of one or more specific goals relating to our performance or the performance of a business unit or the recipient over a specified period of time (in the case of performance awards). Performance-based measures could be based on various factors such as our revenues, cost reductions, operating income, income before taxes, net income, adjusted net income, earnings per share, adjusted earnings per share, operating margins, working capital measures, return on assets, return on equity, return on invested capital, cash flow measures, market share, and/or economic value added or such factors as they apply to one of its business units within which the recipient is primarily employed. The performance goals of the performance awards will be set by the Compensation Committee within the time period prescribed by Section 162(m) of the Code.

        Except to the extent that the Compensation Committee specifies a longer vesting schedule in the award agreement, restricted stock awards given to non-employee Directorsdirectors (and to employee Directorsdirectors in their capacities as directors) will vest on the first anniversary of the grant date. Except as otherwise provided in the award agreement, restricted stock awards given to employees will vest ratably on the first, second and third anniversaries of the grant date. The Plan provides that if the recipient's service with the Company as a Directordirector or employee terminates as a result of the recipient's death, any restricted stock awarded under the Plan will automatically vest, and if such service terminates as a result of disability, the next tranche of shares will automatically vest. The Plan also provides for the acceleration of vesting of a restricted stock award if such accelerated vesting is provided under any benefit plan of the Company to which the recipient is subject. In addition, the Plan gives the Compensation Committee the authority, in its discretion, to accelerate the vesting of any restricted stock award and, in connection with a change in control, to "cash out" any unvested restricted stock award, whether vested or unvested.award.

Risk Considerations in Our Compensation Program

        The Compensation Committee has considered the risks that may exist in the Company's compensation plans and the factors that mitigate against the plans creating material risks to the Company and believes that risks arising from our compensation policies and practices for our employees are not likely to have a material adverse effect on the Company.

However, if a Change in Control (as defined in the severance agreements to generally include a person or group acquiring more than 50% of our stock, a majority of our Board being replaced during any 12-month period if not endorsed by our current Board, a merger or consolidation unless the Company's stockholders hold at least 80% of the voting stock of the surviving entity, a sale of all or substantially all of the Company's assets, or the approval of a plan of complete liquidation by the Company's stockholders) occurs, the term will not end before the second anniversary of the Change in Control.

        Under the severance agreements, upon termination of employment for any reason, the NEO will be entitled to his (a) earned but unpaid base salary through the termination date, (b) accrued and unused paid time off through the termination date, and (c) reimbursement of expenses. Subject to certain conditions (such as signing a release), if an NEO is terminated (1) by the Company for any reason other than for Cause, Unacceptable Performance, Disability or death or (2) by the NEO for Adequate Reason (each such capitalized term as defined in the severance agreements), then the NEO will be entitled to certain benefits, unless termination occurs during a Change in Control Coverage Period (as defined in the severance agreements).

In addition, for the partial fiscal year in which the termination occurs, the NEO will be entitled to a pro rated bonus (based on the number of full or partial months the NEO worked in the partial fiscal year) to the extent such bonus would have been earned under his applicable bonus plan if his employment had continued through the next bonus payment date.

        This report confirms that the Audit Committee has (1) reviewed and discussed the audited financial statements for the year ended July 31, 20122014 as well as the unaudited financial statements included in Quarterly Reports on Form 10-Q for each of the first three quarters of the fiscal year, with management and Cantel's independent registered public accounting firm; (2) discussed with our independent registered public accounting firm the matters required to be reviewed pursuant to the Statement on Auditing Standards No. 61 (Communications with Audit Committees), as amended, as adopted by the Public Company Accounting Oversight Board in Rule 3200T;Auditing Standard No. 16; (3) received the written disclosures and the letter from our independent registered public accounting firm required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm communications with the Audit Committee concerning independence; and (4) discussed with our independent registered public accounting firm their independence. The Audit Committee has considered the compatibility of the independent registered public accounting firm's provision of non-audit services with maintaining the firm's independence and found the provision of such services to be compatible with the firm's independence.

        Based upon the above review and discussions, the Audit Committee recommended to the Board that the Company's audited financial statements for the year ended July 31, 20122014 be included in our Annual Report on Form 10-K for filing with the Securities and Exchange Commission.

PROPOSAL 2

APPROVAL OF AMENDMENT TO
CERTIFICATE OF INCORPORATION TO INCREASE COMMON STOCK

        The Board has adopted a resolution declaring it advisable and in the best interests of Cantel and the stockholders to amend our Certificate of Incorporation, as amended (the Certificate) to increase the authorized number of shares of our common stock, par value $.10 per share, from 30,000,000 to 75,000,000 shares.

        The Certificate presently authorizes 30,000,000 shares of common stock, of which 27,171,293 shares were issued and outstanding as of November 14, 2012, the record date for the Annual Meeting; and 1,000,000 shares of preferred stock, one dollar ($1.00) par value, none of which is presently issued and outstanding. As of November 14, 2012, 2,823,939 shares of common stock were held by us as treasury shares. As such, a total of 29,995,232 shares were issued as of November 14, 2012. Additionally, as of that date an aggregate of 895,638 shares of common stock were reserved for issuance upon the exercise of outstanding options or upon grants of stock options or other awards under our 2006 Equity Incentive Plan. Therefore, upon the exercise of outstanding options or upon grant of stock awards or if we desire to issue common equity for stock splits or acquisitions or to obtain funds through an offering or for any other purpose, we are currently limited to the issuance of 4,768 shares of common stock or the reissuance of our treasury shares.

        The Board considers it desirable to have available for issuance sufficient authorized shares of common stock to enable us to act without delay of seeking stockholder approval if favorable opportunities arise to raise additional equity capital or to acquire companies or products by the issuance of shares of common stock and otherwise to be in a position to take various steps requiring the issuance of additional shares of common stock (including stock splits or stock dividends) that in the judgment of the Board are in our best interests. The shares will also be available for issuance under current and future equity compensation plans. Other than issuances upon exercise of outstanding stock options and future grants under our 2006 Equity Incentive Plan, we have no current plans, arrangements or understandings regarding the issuance of any additional shares of common stock for which authorization is sought and there are no negotiations pending with respect to the issuance thereof for any purpose.

        Additional shares of common stock authorized pursuant to this proposal would be identical in all respects to the common stock now authorized. While authorization of the additional shares will not currently dilute the proportionate voting power or other rights of existing stockholders, future issuances of common stock could reduce the proportionate ownership of existing holders of common stock, and, depending on the price at which such shares are issued, may be dilutive to the existing stockholders.

        Common stock (including the additional shares of common stock authorized pursuant to this proposal) and preferred stock may be issued from time to time upon authorization of the Board, without further approval by the stockholders, unless otherwise required by applicable law, and for the consideration that the Board may determine is appropriate and as may be permitted by applicable law.

        As provided for by the Delaware General Corporation Law, the Board has directed that the proposed amendment to increase the number of authorized shares of common stock be submitted to a vote of the stockholders. Approval of the proposed amendment requires the affirmative vote of a majority of the votes entitled to be cast by the holders of common stock.

        Although an increase in the authorized shares of our capital stock could, under certain circumstances, also be construed as having an anti-takeover effect (for example, by permitting easier dilution of the stock ownership of a person seeking to effect a change in the composition of the Board or contemplating a tender offer or other transaction resulting in our acquisition by another company), the proposed increase is not in response to any effort by any person or group to accumulate our stock

or to obtain control of Cantel by any means. In addition, the proposal is not part of any current plan by the Board to recommend or implement a series of anti-takeover measures or any other corporate transactions.

        The proposed amendment to the Certificate would amend Article Fourth of the Certificate by striking out the first sentence of Article FOURTH, up to the colon, as it now exists and inserting in lieu and instead thereof the following:

"FOURTH:    The total number of shares of all classes of stock that the Corporation shall have authority to issue is Seventy Six Million (76,000,000), of which Seventy Five Million (75,000,000) shall be shares of Common Stock, par value $0.10 per share, and One Million (1,000,000) shall be shares of Preferred Stock, par value $1.00 per share, and the voting powers, designations, preferences and relative, participating, optional or other special qualifications, limitations or restrictions thereof are as follows:"

        If approved by the requisite number of shares, the amendment to our Certificate will become effective upon filing the Certificate of Amendment with the Delaware Secretary of State, which is expected to occur promptly following the meeting.

The Board recommends that stockholders vote "FOR" Proposal 2 to approve the amendment to the Company's Certificate of Incorporation.

PROPOSAL 3

ADVISORY VOTE ON EXECUTIVE COMPENSATION
(SAY-ON-PAY VOTE)

        As required by Section 14A of the Exchange Act, we are providing our stockholders with a vote on a non-binding, advisory basis on the compensation of our Named Executive Officers, as such compensation is disclosed under Item 402 under the SEC's Regulation S-K in the Compensation Discussion and Analysis section of this Proxy Statement, the accompanying tabular disclosure regarding such compensation and the related narrative disclosure. We urge our stockholders to review the Compensation Discussion and Analysis section of this Proxy Statement and the related executive compensation tables and narratives for more information about our NEOs' compensation.

        Our executive compensation programs are designed to enable us to attract, motivate and retain executive talent, who are critical to our success. Consistent with our performance-based compensation philosophy, we reserve the largest portion of potential compensation for performance- and equity-based programs. Our performance-based bonus program rewards the Company's executive officers for achievement of key operational goals that we believe will provide the foundation for creating long-term stockholder value, while our equity awards, mainly in the form of restricted stock, reward long-term performance and align the interests of management with those of our stockholders.

        Among the various forms of performance-based compensation, we believe that equity awards, in particular, serve to align the interests of our executives with those of our long-term stockholders by encouraging long-term performance. As such, equity awards are a key component of our executive compensation program. Equity awards closely align the long-term interests of our executives with those of our stockholders because the value of such awards is dependent upon the Company's stock price. In addition, equity awards align with our growth strategy and provide significant financial upside if our growth objectives are achieved, while placing a significant portion of our executives' compensation at-risk if our objectives are not achieved.

        The Board believes that the information provided above and within the Compensation Discussion and Analysis section of this Proxy Statement demonstrates that our executive compensation program was designed appropriately and is working to ensure that management's interests are aligned with our

stockholders' interests and support long-term value creation. Accordingly, the following resolution is to be submitted for a stockholder vote at the meeting:

"RESOLVED, that the Company's stockholders approve, on an advisory basis, the compensation of the Named Executive Officers, as disclosed pursuant to Item 402 of Securities and Exchange Commission Regulation S-K, including the Compensation Discussion and Analysis, the compensation tables and narrative disclosures in this Proxy Statement."

        Because the vote is advisory, it will not be binding on the Board. The vote on this proposal is not intended to address any specific element of compensation. However, the Board and the Compensation Committee will review the voting results and take into account the outcome when considering future executive compensation arrangements. The Board and management are committed to our stockholders and understand that it is useful and appropriate to obtain the views of our stockholders when considering the design and initiation of executive compensation programs.

        The Board recommends that stockholders vote "FOR" Proposal 32 to approve the compensation of the Company's Named Executive Officers, as described in the Compensation Discussion and Analysis, the compensation tables and narrative disclosures in this Proxy Statement.
