                                 GUARANTEE

               GUARANTEE dated as of November 29, 1999, by Water Pik
Technologies, Inc., a Delaware corporation (the "Guarantor"), in favor of The
Chase Manhattan Bank, a New York banking corporation, as agent ("Agent") for (i)
the Lenders (the "Lenders") named in Schedule 2.01 of the Restated Credit
Agreement dated as of the date hereof, among Water Pik, Inc., a Delaware
corporation ("Water Pik" or a "Borrower"), Laars, Inc., a Delaware corporation
("Laars" or a "Borrower" and together with Water Pik, the "Borrowers"), the
Guarantor, the Lenders named therein, and the Agent (as amended, modified or
supplemented from time to time in accordance with its terms, the "Credit
Agreement"; capitalized terms used herein and not otherwise defined herein shall
have the meanings attributed thereto in the Credit Agreement) and (ii) itself as
issuer of the Letters of Credit.

               The Agent and the Lenders have agreed to extend Loans and certain
other financial accommodations to, including, without limitation, the issuance
of the Letters of Credit for the account of the Borrowers pursuant to, and
subject to the terms and conditions of, the Credit Agreement. The obligation of
the Lenders to extend such Loans and of the Agent to issue the Letters of Credit
under the Credit Agreement is conditioned on the execution and delivery by the
Guarantor of a guarantee in the form hereof of the Obligations (such Obligations
to include, without limitation, the due and punctual payment and performance of
(a) the principal of and interest on the Loans, when and as due, whether at
maturity, by acceleration, upon one or more dates set for prepayment or
otherwise, (b) Indebtedness at any time and from time to time under the Letters
of Credit, (c) all other obligations of the Borrowers at any time and from time
to time under the Credit Agreement and the other Loan Documents and (d) all
obligations of the Guarantor at any time and from time to time under the Loan
Documents).

               Accordingly, in consideration of the premises and in order to
induce the Agent and the Lenders to make Loans and extend other financial
accommodations under the Credit Agreement, the Guarantor hereby agrees as
follows:

               Section 1. Guarantee. The Guarantor hereby irrevocably and
unconditionally guarantees the punctual payment when due, whether at stated
maturity, by acceleration or otherwise, and the punctual performance, of all
present and future Obligations of the Borrowers (the foregoing being herein
referred to as the "Guaranteed Obligations");

               Section 2. Waiver. The Guarantor hereby absolutely,
unconditionally and irrevocably waives, to the fullest extent permitted by law,
(i) promptness, diligence, notice of acceptance and any


                                        1
<PAGE>   2
other notice with respect to this Guarantee, (ii) presentment, demand of
payment, protest, notice of dishonor or nonpayment and any other notice with
respect to the Guaranteed Obligations, (iii) any requirement that the Agent or
Lenders protect, secure, perfect or insure any security interest or Lien or any
property subject thereto or exhaust any right or take any action against the
Borrowers or any other person or any Collateral, and (iv) any other action,
event or precondition to the enforcement of this Guarantee or the performance by
the Guarantor of the obligations hereunder.

               Section 3. Guarantee Absolute. (a) The Guarantor guarantees that,
to the fullest extent permitted by law, the Guaranteed Obligations will be paid
or performed strictly in accordance with their terms, regardless of any law,
regulation or order now or hereafter in effect in any jurisdiction affecting any
of such terms or the rights of the Agent or any Lender with respect thereto.

               (b) No invalidity, irregularity, voidability, voidness or
unenforceability of the Credit Agreement, the Notes, or any other Loan Document
or any other agreement or instrument relating thereto, or of all or any part of
the Guaranteed Obligations or of any security therefor shall affect, impair or
be a defense to this Guarantee.

               (c) This Guarantee is one of payment and performance, not
collection, and the obligations of the Guarantor under this Guarantee are
independent of the Obligations of the Borrowers, and a separate action or
actions may be brought and prosecuted against the Guarantor to enforce this
Guarantee, irrespective of whether any action is brought against the Borrowers
or whether the Borrowers are joined in any such action or actions.

               (d) The liability of the Guarantor under this Guarantee shall be
absolute and unconditional irrespective of:

                      (i) any change in the manner, place or terms of payment or
       performance, and/or any change or extension of the time of payment or
       performance of, renewal or alteration of, any Obligation, any security
       therefor, or any liability incurred directly or indirectly in respect
       thereof, or any other amendment or waiver of or any consent to departure
       from the Credit Agreement or the Notes or any other Loan Document,
       including any increase in the Guaranteed Obligations resulting from the
       extension of additional credit to the Borrowers or any of their
       subsidiaries or otherwise;

                      (ii) any sale, exchange, release, surrender, realization
       upon any property by whomsoever at any time pledged or mortgaged to
       secure, or howsoever securing, all or any of the Guaranteed Obligations,
       and/or any offset against, or failure to perfect, or continue the
       perfection of, any Lien in any such property, or delay in the perfection
       of any such Lien, or any amendment or waiver of or consent to departure
       from any other guarantee for all or any of the Guaranteed Obligations;


                                        2
<PAGE>   3
                      (iii) any exercise or failure to exercise any rights
       against the Borrowers or others (including the Guarantor);

                      (iv) any settlement or compromise of any Obligation, any
       security therefor or any liability (including any of those hereunder)
       incurred directly or indirectly in respect thereof or hereof, and any
       subordination of the payment of all or any part thereof to the payment of
       any Obligation (whether due or not) of the Borrowers to creditors of the
       Borrowers other than the Guarantor;

                      (v) any manner of application of Collateral, or proceeds
       thereof, to all or any of the Guaranteed Obligations, or any manner of
       sale or other disposition of any Collateral for all or any of the
       Guaranteed Obligations or any other assets of the Borrowers or any of
       their subsidiaries;

                      (vi) any change, restructuring or termination of the
       existence of the Borrowers or any of their subsidiaries; or

                      (vii) any other agreements or circumstance of any nature
       whatsoever which might otherwise constitute a defense available to, or a
       discharge of, this Guarantee and/or obligations of the Guarantor
       hereunder, or a defense to, or discharge of, the Borrowers or any other
       person or party relating to this Guarantee or the obligations of the
       Guarantor hereunder or otherwise with respect to the Loans, Letters of
       Credit or other financial accommodations to the Borrowers.

               (e) The Agent may at any time and from time to time (whether or
not after revocation or termination of this Guarantee) without the consent of,
or notice (except as shall be required by applicable statute and cannot be
waived) to, the Guarantor, and without incurring responsibility to the Guarantor
or impairing or releasing the obligations of the Guarantor hereunder, apply any
sums by whomsoever paid or howsoever realized to any Guaranteed Obligation
regardless of what Guaranteed Obligations remain unpaid.

               (f) This Guarantee shall continue to be effective or be
reinstated, as the case may be, if claim is ever made upon the Agent or any
Lender for repayment or recovery of any amount or amounts received by the Agent
or such Lender in payment or on account of any of the Guaranteed Obligations and
the Agent or such Lender repays all or part of said amount by reason of any
judgment, decree or order of any court or administrative body having
jurisdiction over the Agent or such Lender or the respective property of each,
or any settlement or compromise of any such claim effected by the Agent


                                        3
<PAGE>   4
or such Lender with any such claimant (including the Borrowers), then and in
such event the Guarantor agrees that any such judgment, decree, order,
settlement or compromise shall be binding upon the Guarantor, notwithstanding
any revocation hereof or the cancellation of any note (including the Notes) or
other instrument evidencing any Obligation, and the Guarantor shall be and
remain liable to the Agent and/or such Lender hereunder for the amount so repaid
or recovered to the same extent as if such amount had never originally been
received by the Agent or such Lender.

               Section 4. Continuing Guarantee. This Guarantee is a continuing
one and shall (i) remain in full force and effect until the indefeasible payment
and satisfaction in full of the Guaranteed Obligations, (ii) be binding upon the
Guarantor, its successors and assigns, and (iii) inure to the benefit of, and be
enforceable by, the Agent and its successors, transferees and assigns. All
obligations to which this Guarantee applies or may apply under the terms hereof
shall be conclusively presumed to have been created in reliance hereon.

       this Guarantee or the consummation of the transactions contemplated
       hereby;

               (d) The execution, delivery and performance by the Guarantor of

       respectively, constituting all of the authorized, issued and outstanding

charged.

               Section 9. Subordination of Subrogation Rights. The Guarantor
hereby waives and releases any and all rights and claims it may now or hereafter
have or acquire against the Borrowers that would constitute it a "creditor" of
the Borrowers for purposes of the Federal Bankruptcy Code, including all rights
of subrogation against the Borrowers and their property and all rights of
indemnification, contribution and reimbursement from the Borrowers and their
property, regardless of whether such rights arise in connection with this

the Guarantor against any and all of the obligations of the Guarantor now or
hereafter existing under this Guarantee, whether or not the Agent or such Lender
shall have made any demand under this Guarantee and although such obligations
may be contingent and unmatured. The Agent agrees promptly to notify the
Guarantor after any such set-off and application, provided that the failure to
give such notice shall not affect the validity of such set-off and application.
The rights of the Agent and Lenders under this Section 10 are in addition to
other rights and remedies (including other rights of set-off) which the Agent
and Lenders may have.

               Section 11. Statute of Limitations. Any acknowledgment or new

limitations shall have expired, prevent the operation of such statute of
limitations.

delay by the Agent shall constitute a waiver of its rights and remedies
hereunder or otherwise. No single or partial waiver by the Agent of any default
hereunder or right or remedy which it may have shall operate as a waiver of any
other default, right or remedy or of the same default, right or remedy on a
future occasion.

any copy of this Guarantee signed by the Guarantor and transmitted by telecopier
