Attn.:  James P. Reilly

Ladies and Gentlemen:

      You have advised Fleet Bank, N.A. ("FLEET") that Cantel Medical Corp., a
Delaware corporation (the "BORROWER") will acquire all the outstanding stock of
the TargetCo pursuant to a statutory merger of TargetCo and Borrower or
Borrower's wholly owned subsidiary (such transaction being the "ACQUISITION").
The Acquisition will be financed, in part, through an equity issuance by you,
and from funds borrowed pursuant to the Credit Facilities (as defined below).

      Fleet is pleased to advise you of its commitment to provide up to the full
amount of $47,500,000 senior secured credit facilities (the "CREDIT FACILITIES")
on the terms and conditions summarized in this letter and in the Summary of
Terms and Conditions attached to this letter (the "TERM SHEET"). The Credit
Facilities will be used (i) to finance, in part, the purchase price for the
Acquisition and to pay fees and expenses of the Acquisition (ii) to repay
existing indebtedness and (iii) for general working capital purposes.

      Although Fleet is committing to provide all of the Credit Facilities on a
fully underwritten basis, Fleet expects that a portion of the Credit Facilities
will be made available by other financial institutions (such lenders including
Fleet, the "LENDERS"). It is agreed that Fleet will act as the sole
administrative agent (in such capacity, the "ADMINISTRATIVE AGENT") for the
Credit Facilities and Fleet Securities, Inc ("FSI") will act as arranger for the
Credit Facilities. Fleet will be responsible for preparing and negotiating
definitive documentation for the Credit Facilities, and Fleet and FSI will
manage the syndication effort of forming the syndicate of lenders that will make
the Credit Facilities available. Additional agents, co-agents or arrangers may
be appointed at the discretion of Fleet and FSI.

      You agree to assist Fleet and FSI in forming any such syndicate and to
provide Fleet, FSI and the other Lenders, promptly upon request, with all
information reasonably deemed necessary by them (consistent with industry
practice) to complete successfully the syndication, including, but not limited
to, (i) an information package for delivery to potential syndicate members and
participants and (ii) all information and projections prepared by you or your
advisers




Cantel Medical Corp.

relating to the transactions described herein. Prior to the closing of the
Credit Facilities you agree to refrain from any other financings (except equity
issuances having no debt characteristics) during such syndication process unless
otherwise agreed to by Fleet. You further agree to make appropriate officers and
representatives of the Borrower and its subsidiaries available to participate in
informational meetings for potential syndicate members and participants at such
times and places as Fleet or FSI may reasonably request.

      Fleet and FSI reserve the right, based on market reception, in
consultation with the Borrower, to reallocate the aggregate principal amount of
the Credit Facilities among the Revolving Facility and the Term Facility (as
defined in the Term Sheet) and/or to otherwise change the structure or terms
thereof prior to the closing of the Credit Facilities if Fleet and FSI
determines that such reallocation or changes are advisable in order to ensure a
successful syndication and if the aggregate amount of the Credit Facilities
remains unchanged and if any pricing changes are consistent with credits of
similar quality.

      You represent and warrant and covenant that (i) all information which has
been or is hereafter made available to Fleet or FSI by you or any of your
representatives in connection with the transactions contemplated hereby is and
will be complete and correct in all material respects with respect to the
matters such information purports to cover and does not and will not contain any
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements contained therein not materially misleading in
light of the circumstances under which such statements have been or will be made
and (ii) all financial projections that have been or are hereafter prepared by
you and made available to Fleet, FSI or any other participants in the Credit
Facilities have been or will be prepared in good faith based upon reasonable
assumptions. You agree to supplement the information and projections referred to
in clauses (i) and (ii) above from time to time until completion of the
syndication so that the representations and warranties in the preceding sentence
remain correct. In arranging and syndicating the Credit Facilities, Fleet and
FSI may use and rely on such information and projections without independent
verification thereof.

      In connection with the syndication of the Credit Facilities, Fleet and FSI
may, in their discretion, allocate to other Lenders portions of any fees payable
to Fleet or FSI in connection with the Credit Facilities. You agree that no
Lender will receive any compensation of any kind for its participation in the
Credit Facilities, except as expressly provided for in this letter, the Term
Sheet or in the Fee Letter referred to below.

      Please note, however, that the terms and conditions of this commitment and
undertaking are not limited to those set forth in this letter. Those matters
that are not covered or made clear herein or in the attached Term Sheet (which
is a part of this Commitment) are subject to mutual agreement of the parties.
The terms and conditions of this commitment and undertaking may be modified only
in writing. In addition, this commitment and undertaking is subject to: (i) the
preparation, execution and delivery of mutually acceptable loan documentation,
including a credit agreement incorporating substantially the terms and
conditions outlined herein and in the Term Sheet, (ii) the absence of (a) a
material adverse change in, or a development that would reasonably be expected
to have a material adverse effect on, the business, condition (financial or
otherwise), operations, properties or prospects of the Borrower and TargetCo and
their respective subsidiaries, taken as a whole, since July 31, 2000 to the date
of this Commitment Letter in respect

material adverse effect on, the condition (financial or otherwise), operations,

respective subsidiaries, taken as a whole, following the date of this Commitment
Letter, and (c) any material adverse change in loan syndication or financial or
capital market conditions generally from those currently in effect that would be
reasonably likely to have a material adverse effect on the ability of Fleet to
successfully syndicate the commitment under this letter, (iii) the accuracy and
completeness in all material respects of all representations, taken as a whole,
that you make to us and all information, taken as a whole, that you furnish to
us in connection with this commitment and undertaking and your compliance with

hereof, and no information becoming known after the date hereof, that (a)

by you or would reasonably be expected to be materially adverse to the condition
(financial or otherwise), business, operations, properties or prospects of the
Borrower and TargetCo and their respective subsidiaries, taken together, or to
the Administrative Agent, the Arranger or the Lenders, or to the legal, tax,
accounting or financial aspects of the Acquisition, or (b) has had or would

upon demand, to pay and reimburse Fleet, FSI and each indemnified person for any
legal or other out-of-pocket expenses incurred in connection with investigating,
defending or preparing to defend any such action, suit, proceeding (including
any inquiry or investigation) or claim (whether or not Fleet, FSI or any such
person is a party to any action or proceeding out of which any such expenses
arise); PROVIDED, HOWEVER, that you shall not have to indemnify any indemnified
person against any loss, claim, damage, expense or liability to the extent that
it resulted from the gross negligence or willful misconduct of such indemnified
person. This letter is issued for your benefit only and no other person or
entity may rely hereon. Under no circumstances shall Fleet, FSI or any of their
respective affiliates be liable to you or any other person for any punitive,
