RE:SEPARATION AGREEMENT AND GENERAL RELEASE

Craig:

Reference is hereby made to the letter agreement by and between you and Cantel Medical Corp. (“Cantel” or the “Company”) dated April 15, 2014 as amended (the “letter agreement”).  Capitalized terms used but not defined herein are used as defined in the letter agreement.  You are signing this Separation and General Release (this “Agreement”) on or within twenty-one (21) days after your Retirement Date (as defined below) in accordance with the terms and conditions of the letter agreement and this Agreement.

This Agreement confirms your agreed upon retirement and termination of employment with Cantel will be effective on May 8, 2015 (the “Retirement Date”).  This Agreement confirms your final pay and benefits and confirms the separation package you will receive if you sign and return the original of this Agreement to the Company in the time frame noted below except as otherwise provided in the letter agreement.

Your final pay and benefits are as follows:

·Base Salary; PTO. Regardless of whether you sign this Agreement, the effective date of your termination of employment is the Retirement Date specified above except as otherwise provided in this Agreement and the letter agreement.  Regardless of whether you sign this Agreement, you will be paid your accrued and unpaid base salary as well as your accrued and unused paid time off (“PTO”) (inclusive of carryover PTO of up to 10 days), if any, through such date.  You will also be entitled to the bonus and other compensation described in the letter agreement.

·Benefits.  Regardless of whether you sign this Agreement, following the Retirement Date you will have the option to elect to continue your medical, dental and life insurance benefits under the Consolidated Omnibus Reconciliation Act of 1985 (“COBRA”) for 18 months or other applicable COBRA continuation period. You will receive COBRA information from Acclaim Benefits, our COBRA Administrator, within fourteen (14) days of your last date of employment, which will include information regarding the payment of your portion of the premiums you will be required to pay for insurance benefits.  All other benefits, including, but not limited to, PTO, and holiday pay, end on your last day of employment.  Your 401(k)

benefits are governed by applicable plan documents.  See discussion below related to the payment of COBRA premiums.

·Restricted Stock.  Regardless of whether you sign this Agreement, all unvested restricted Cantel stock held by you on the Retirement Date will vest on the Retirement Date.

·You will be entitled to receive an additional bonus of $77,377.42, comprised of $8,300 per month for each full month you were employed by Cantel during the fiscal year ending July 31, 2015 and pro rata for May 2015, which will be payable to you within ten (10) calendar days following the Retirement Date.

·You will continue to participate in Cantel’s Annual Incentive Compensation Plan (the “STIP”), and thereby remain eligible for your annual bonus thereunder, for the fiscal year ending July 31, 2015, subject to the terms of the STIP.  Your STIP bonus will be determined on a pro rata basis, based on the number of days you are employed by Cantel during the period from August 1, 2014 through the Retirement Date, which will be paid to you at the same time that executive officers of Cantel are paid their STIP bonuses.

Following the Retirement Date you will be entitled to the severance benefits listed below (the “Severance Benefits”), subject to the terms and conditions of this Agreement and the letter agreement.  All of the Severance Benefits are subject to (i) your delivery to the Company of this Agreement, signed by you, no earlier than the Retirement Date and no later than the  twenty-first (21st) day following such Retirement Date (such twenty-first (21st) day, the “Release End Delivery Date”), (ii) the expiration of the seven (7) day period following your execution of  this Agreement (the “Rescission Period”) without rescission by you, and (iii) your compliance with all other terms and conditions of this Agreement applicable to you. The signed Agreement should be delivered to Chris Geschickter, VP, Human Resources, 150 Clove Road, 9th Floor, Little Falls, NJ 07424 or to the Company’s General Counsel.  If you execute and deliver  this Agreement to the Company and the Rescission Period expires without rescission of this Agreement by you, the fifth business day following the last day of such Rescission Period is referred to herein as the “Payment Date”; provided, however, that if the fifth business day following the 7th day after the Release End Delivery Date falls in the calendar year next succeeding the calendar year of the Retirement Date, the Payment Date will be no earlier than the first business day of such next succeeding calendar year.  You will receive a copy of the fully executed Agreement from the Company.

·Severance Payment.  The Company will pay you a severance payment in the gross amount of $700,000 (net of applicable taxes and withholdings) in a lump sum on the date that is six months plus one day following the Retirement Date (or the next business day thereafter).

·COBRA Benefits.  The Company will pay the Company portion of the premiums for COBRA continuation coverage for you under the Company’s group medical and dental plans for 18 months, beginning on your election of COBRA continuation coverage. The Company will make such payment when due commencing after the Payment Date.  In addition, on or about the last day of such 18th month, the Company will pay you a lump sum amount equal to six (6) times the amount of the monthly premium paid by the

2

Company for such 18th month (the “Additional Insurance Payment”). As a condition to the Company’s obligation to make the premium payments and lump sum payment, you (i) must be participating in the Company’s group medical and dental plans immediately prior to the Retirement Date; and (ii) must elect COBRA continuation coverage.  In addition, such obligations will immediately terminate if and when you become eligible through another employer for medical insurance with benefits not substantially less favorable than those under Cantel’s current medical insurance plan.

·D&O Insurance.  You will continue to be entitled to any rights to insurance and indemnification under any directors and officers liability insurance, including any ERISA rider (“D&O Insurance”), Certificate of Incorporation, and Bylaws, of the Company or a Related Employer (as defined below) as in effect before the Retirement Date (or rights to insurance and indemnification that are substantially the same thereto), with respect to any claims relating to the period before the Retirement Date.  Additionally, any and all D&O Insurance policies obtained by Cantel or a Related Employer following the Retirement Date that are “claims made” polices will cover you to the same extent as other former officers of Cantel.  The term “Related Employer” means Cantel and any other employer that is required to be aggregated with Cantel pursuant to Section 414(b), (c), or (m) of the Internal Revenue Code, as amended.

·Change in Control Payment. If (i) a “Change in Control” of Cantel (as defined in the Amended and Restated Executive Severance Agreement between you and Cantel dated as of October 31, 2012 (the “2012 Severance Agreement”) occurs within six months after the Retirement Date, or (ii) a “Potential Change in Control” of Cantel (as defined in the 2012 Severance Agreement”) occurred prior to the Retirement Date and a resulting “Change in Control” of Cantel occurs within two years following the Retirement Date, then Cantel will pay you lump sum of $220,000 (plus interest, if applicable) in accordance with the terms set forth in paragraph 15 of the letter agreement.

·All payments, benefits and Severance Benefits made to you under this Agreement are subject to all applicable federal, state and local tax withholdings and any other withholdings required by law.

·By signing this Agreement, you agree that the Severance Benefits constitute adequate consideration for your release and waiver of any and all claims as set forth below.  For valuable consideration you receive from Cantel pursuant to this Agreement, you (on your own behalf and on behalf of your heirs, executors, administrators, trustees, legal representatives, successors and assigns) hereby release, waive and forever discharge all claims, demands, causes of actions, administrative claims, obligations, liabilities, claims for punitive or liquidated damages or penalties, any other damages, any claims for costs, disbursements or attorney’s fees, any individual or class action claims, or any other claims or demands of any nature whatsoever, whether asserted or unasserted, known or unknown, absolute or contingent that you have or may have against Cantel, any parent, subsidiary, division, or affiliate of the Company, any of  its or their past, present or future owners, present, former or subsequent insurers, agents, representatives, officers, directors, shareholders, managers, members, employees, representatives or consultants, and the current or former administrators or trustees of
