                                HARMONY BROOK, INC.
                        SPECIAL MEETING OF SHAREHOLDERS
                           TO BE HELD MARCH 13, 1998
 
    This Proxy Statement is being furnished to shareholders of Harmony Brook,
Inc., a Minnesota corporation ("Harmony" or the "Company"), in connection with
the solicitation of proxies by the Board of Directors of Harmony for use at the
Company's Special Meeting of Shareholders, to be held at the Courtyard by
Marriott, Minneapolis--St. Paul Airport, 1352 Northland Drive, Mendota Heights,
Minnesota 55120 at 10:00 a.m., Minneapolis time, on March 13, 1998, or any
adjournment or postponement thereof (the "Special Meeting"). The Special Meeting
is being held to consider and act upon a proposal to approve the Agreement and
Plan of Merger and Reorganization, attached hereto as Appendix A (the "Merger
Agreement"), pursuant to which Culligan Acquisition Corp. ("Merger Sub") will be
merged with and into Harmony (the "Merger"), with Harmony being the surviving
corporation and a wholly-owned subsidiary of Culligan International Company
("Culligan"). By virtue of the Merger, each outstanding share of Harmony Common
Stock will be converted into the right to receive $0.545 in cash. This Proxy
Statement and form of Proxy are first being sent to shareholders on or about
February 19, 1998.
 
    Any shareholder giving a proxy may revoke it at any time before the
convening of the Special Meeting. Revocation must be in writing, signed in
exactly the same manner as the Proxy, and dated. Revocations of proxies will be
honored if received at the offices of the corporate secretary, Nancy A. Quam,
Corporate Secretary, 601 Lakeshore Parkway, Suite 1140, Minneapolis, Minnesota
55305, on or before March 12, 1998. In addition, on the day of the Special
Meeting, prior to the convening thereof, revocations may be delivered to the
tellers who will be seated at the door of the meeting room. Proxies will be
voted as specified by the shareholders. Proxies which are signed by shareholders
but which lack any specification will be voted in favor of the approval of the
Merger Agreement and will be deemed to confer authority on the appointed Proxies
to vote in their discretion on other matters which may properly come before the
Special Meeting. If a shareholder abstains from voting as to any matter, then
the shares held by such shareholder shall be deemed present at the meeting for
purposes of determining a quorum and for purposes of calculating the vote with
respect to such matter, but shall not be deemed to have been voted in favor of
such matter. If a broker returns a "non-vote" proxy, indicating a lack of
authority to vote on such matter, then the shares covered by such non-vote shall
be deemed present at the meeting for purposes of determining a quorum but shall
not be deemed to be represented at the meeting for purposes of calculating the
vote with respect to such matter.
 
    Proxies are being solicited on behalf of Harmony by its Board of Directors.
The cost of soliciting Proxies, including the preparation and assembly of the
proxies and solicitation material, as well as the cost of forwarding such
material to beneficial owners of Harmony Common Stock, will be borne by the
Company. Directors, officers and regular employees of Harmony may, without
compensation other than their regular compensation, solicit proxies personally
or by telephone.
 
    THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND
RECOMMENDS THAT SHAREHOLDERS VOTE FOR APPROVAL OF THE MERGER AGREEMENT.
 
    No person is authorized to give any information or make any representation
not contained in this Proxy Statement and, if given or made, such information or
representation should not be relied upon as having been authorized. The delivery
of this Proxy Statement shall not under any circumstances create an implication
that there has been no change in the affairs of Harmony or Culligan or in the
information set forth herein since the date of this Proxy Statement.

BACKGROUND OF THE MERGER:
 
    The terms of the Merger Agreement are the results of arm's-length
negotiations between representatives of Culligan and Harmony. In September,
1997, Culligan initiated contact with Harmony to consider possible strategic
business transactions. After several conversations and meetings, in September,
1997, Culligan proposed, in a letter of intent, to acquire all of the
outstanding Common Stock of Harmony at a price of $0.55 per share.
 
                                       2
<PAGE>
    On September 25, 1997, the Board of Directors of Harmony approved the letter
of intent, subject to the receipt of a fairness opinion from an investment
banker to be selected by the Board of Directors, and Culligan and Harmony
entered into the letter of intent. See "The Merger -- Opinion of Investment
Banker."
 
    In December of 1997, following completion by Culligan of its due diligence
examination of Harmony, Culligan's offer was revised to provide for a purchase
price of $0.545 per share.
 
    Harmony and Culligan negotiated the terms of the Merger Agreement. On
December 24, 1997, John G. Kinnard & Co. ("Kinnard") presented its fairness
opinion and the Board of Directors of Harmony unanimously approved the execution
of the Merger Agreement.
 
POSSIBLE CONFLICTS OF INTEREST:
 
    Following the Merger, James C. Hawley, Harmony's President and Chief
Executive Officer, is expected to be employed by the surviving corporation in a
similar capacity. In connection with such continued employment, Mr. Hawley will
be entitled to receive a severance benefit equal to 12 months compensation if
his employment is involuntarily terminated.
 
    Donald R. Brattain, Harmony's Chairman of the Board, will enter into a
non-competition agreement in which he will agree, for a period of two years
following consummation of the Merger, not to engage in any business competitive
with the business of Harmony. As a condition to the consummation of the Merger,
Mr. Brattain has also agreed to indemnify Culligan against certain
misrepresentations and breaches of warranty on the part of Harmony under the
Merger Agreement, up to a maximum indemnification obligation of $1,000,000. Mr.
Brattain has also provided bridge financing to Harmony in an amount of $50,000
as of the date of this Proxy Statement. The Company expects to borrow up to an
additional $250,000 from Mr. Brattain prior to consummation of the Merger. In
consideration of Mr. Brattain's delivery of the non-competition agreement,
indemnification agreement and bridge financing, Harmony will pay him the sum of
$40,225, payable upon consummation of the Merger.
 
    Upon consummation of the Merger, all holders of employee incentive stock
options to purchase Harmony Common Stock, including Harmony's executive
officers, but not including its directors, will receive, for each share subject
to an option, a cash payment equal to $0.05 per share.
 
    See "The Merger -- Possible Conflicts of Interest."
 
REASONS FOR THE MERGER:
 
    In reaching their conclusion to approve the Merger Agreement and to
recommend the approval of the Merger Agreement by the Harmony shareholders, the
Harmony Board of Directors considered, among other factors, the competitive
environment in the water vending marketplace; the significant premium offered by
the Merger over the trading price of Harmony Common Stock prior to the
announcement of the proposed Merger; Culligan's ability to support and
supplement Harmony's management team with financial and other resources and to
provide the advantages of a large-scale distribution network; the business,
financial condition, results of operations and prospects of Harmony on both an
historical and prospective basis; and the current and historical market prices
of Harmony Common Stock. The Board of Directors also considered the fairness
opinion given by John G. Kinnard & Co. ("Kinnard") on December 24, 1997 to the
effect that the consideration to be received by Harmony shareholders in the
Merger is fair to such shareholders from a financial point of view. See "The
Merger -- Harmony's Reasons for the Merger; Recommendation of the Harmony Board
of Directors," "The Merger -- Opinion of Investment Banker," and "Stock Prices
and Dividends."

<PAGE>
HARMONY'S INVESTMENT BANKER:
 
    Kinnard was retained by Harmony to render a fairness opinion to the Board of
Directors in connection with the Merger. Kinnard undertook a formal analysis of
the financial consideration to be received by Harmony shareholders in the Merger
and presented its opinion and distributed information supporting this opinion to
the Harmony Board on December 24, 1997. Kinnard reaffirmed its opinion as of the
date of the mailing of this Proxy Statement. The full extent of Kinnard's
opinion, as reaffirmed, which contains information as to the assumptions made,
matters considered and the scope and limitations on the review undertaken, is
set forth as Appendix C to this Proxy Statement and should be read in its
entirety. See "The Merger -- Opinion of Investment Banker."
 
EFFECTIVE TIME OF THE MERGER:
 
    As soon as practicable following approval of the Merger Agreement by the
requisite vote of the Harmony shareholders and the satisfaction or waiver of the
other conditions to the Merger, Articles of Merger will be filed with the
Minnesota Secretary of State, at which time the Merger will become effective.
See "The Merger -- Conditions."
 
CONDITIONS TO THE MERGER; TERMINATION:
 
    Consummation of the Merger is conditioned upon the fulfillment of certain
conditions set forth in the Merger Agreement. See "The Merger -- Conditions."
The Merger Agreement may be terminated (i) by mutual consent of Culligan and
Harmony; (ii) by either Culligan or Harmony if the Merger has not been
consummated before March 15, 1998 for a reason other than the failure of the
terminating party to comply with its obligations under the Merger Agreement;
(iii) by Culligan if (a) there has been a material breach on the part of Harmony
in the representations, warranties or covenants of Harmony set forth in the
Merger Agreement, or any material failure on the part of Harmony to comply with
its obligations thereunder, (b) Harmony's shareholders do not approve of the
Merger Agreement at the Special Meeting, or (c) the Board of Directors of
Harmony withdraws, amends or modifies its recommendation of the Merger
Agreement; or (iv) by Harmony if (a) there has been a material breach on the
part of Culligan in the representations, warranties or covenants of Culligan set
forth in the Merger Agreement, or any material failure on the part of Culligan
to comply with its obligations thereunder, or (b) Harmony's shareholders do not
approve of the Merger Agreement at the Special Meeting. See "The Merger --
Termination and Amendment."
 
EXPENSES AND FEES:
 
    Except as set forth in the following sentence, Harmony and Culligan will
each bear its own expenses in connection with the Merger Agreement and the
transactions contemplated thereby, whether or not the Merger is consummated. See
"Expenses of the Merger." In the event the Merger is not consummated because of
a failure of Harmony's shareholders to approve the Merger, or the Board of
Directors of the Company withdraws, amends or modifies its favorable
recommendation of the Merger, Culligan shall be entitled to a termination fee of
$500,000 if Harmony enters into an agreement, arrangement or understanding
providing for the sale or other disposition of its business or a "Competing
Transaction" (as defined in the Merger Agreement), within twelve months
following such termination.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES:
 
    The receipt of cash by Harmony shareholders, either in accordance with the
terms of the Merger Agreement or as a result of exercising dissenters' rights,
will require each shareholder to recognize gain or loss (generally capital gain
or loss) in an amount equal to the difference between the amount received by the
shareholder and the shareholder's tax basis in his or her Harmony Common Stock.
Harmony shareholders should read the discussion under "The Merger -- Federal
Income Tax Consequences" and should consult with their own tax advisors.

                              GENERAL INFORMATION
 
    This Proxy Statement is furnished in connection with the solicitation by the
Board of Directors of Harmony Brook, Inc. ("Harmony" or the "Company") of
proxies to be voted at the Special Meeting to be held March 13, 1998.
 
    At the Special Meeting, Harmony shareholders will be asked to consider and
vote upon the approval of the Merger Agreement providing for the merger of
Merger Sub, a wholly-owned subsidiary of Culligan, with and into Harmony, as a
result of which Harmony will become a wholly-owned subsidiary of Culligan. A
copy of the Merger Agreement is attached as Appendix A to this Proxy Statement.
 
    The Board of Directors of Harmony has unanimously approved the Merger
Agreement. The Board of Directors of Culligan, the initial Board of Directors of
Merger Sub, and Culligan, as the sole shareholder of Merger Sub, have also
approved the Merger Agreement.
 
    Pursuant to the Merger Agreement, upon effectiveness of the Merger, each
outstanding share of Harmony Common Stock, except for shares of Harmony Common
Stock held by shareholders who perfect dissenters' rights under Minnesota law,
will be converted into the right to receive $0.545 in cash. See "The Merger --
Rights of Dissenting Shareholders." See also Sections 302A.471 and 302A.473 of
the Minnesota Business Corporation Act attached hereto as Appendix B.
 
    The close of business on February 17, 1998 (the "Record Date") has been
fixed as the record date for determination of the holders of Harmony Common
Stock who are entitled to notice of and to vote at the Special Meeting. As of
the Record Date, there were 8,045,161 shares of Harmony Common Stock outstanding
held by approximately 133 holders of record, of which 2,285,582 shares, or
approximately 28%, were held by Harmony directors, executive officers and their
affiliates.
 
    The affirmative vote of the holders of the majority of the outstanding
shares of Harmony Common Stock is required for approval of the Merger Agreement.
The holders of record on the Record Date of shares of Harmony Common Stock are
entitled to one vote per share at the Special Meeting. As of the Record Date,
certain officers and directors of Harmony and their affiliates owned a total of
2,285,582 shares of Harmony Common Stock (excluding shares issuable pursuant to
stock options exercisable within sixty days of the Record Date), constituting
approximately 28% of the outstanding Harmony Common Stock, and have indicated
that they intend to vote for approval of the Merger Agreement. The presence at
the Special Meeting in person or by proxy of the holders of a majority of the
outstanding shares of Harmony Common Stock entitled to vote shall constitute a
quorum for the transaction of business. If a shareholder abstains from voting as
to any matter, then the shares held by such shareholder shall be deemed present
at the meeting for purposes of determining a quorum and for purposes of
calculating the vote with respect to such matter, but shall not be deemed to
have been voted in favor of such matter. If a broker returns a "non-vote" proxy,
indicating a lack of authority to vote on such matter, then the shares covered
by such non-vote shall be deemed present at the meeting for purposes of
determining a quorum but shall not be deemed to be represented at the meeting
for purposes of calculating the vote with respect to such matter.
 
    The Harmony Board of Directors is not aware of any business to be acted upon
at the Special Meeting other than as described herein. If, however, other
matters are properly brought before the Special Meeting, the persons appointed
as Proxies will have discretion to vote thereon in accordance with their best
judgment.
 
    A proxy card is enclosed for use by Harmony shareholders. Such shareholders
are solicited on behalf of the Board of Directors of Harmony to SIGN AND RETURN
THE ENCLOSED PROXY CARD. All properly executed proxies not revoked will be voted
at the Special Meeting in accordance with the instructions contained therein.
Proxies containing no instructions will be voted in favor of approval of the
Merger Agreement. A shareholder who has executed and returned a proxy may revoke
it at any time before the convening of the Special Meeting. Revocation must be
in writing, signed in exactly the same
 
                                       6
<PAGE>
manner as the proxy , and dated. Revocations of proxies will be honored if
received at the offices of the corporate secretary, Nancy A. Quam, 601 Lakeshore
Parkway, Suite 1140, Minneapolis, Minnesota 55305 on or before March 12, 1998.
In addition, on the day of the Special Meeting, prior to the convening thereof,
revocations may be delivered to the tellers who will be seated at the door of
the meeting room.
 
    Representatives of Coopers & Lybrand L.L.P., Harmony's independent
accountants, are expected to be present at the Special Meeting. Such
representatives will have the opportunity to make a Statement if they so desire
and are expected to be available to respond to appropriate questions.
 
    THE BOARD OF DIRECTORS OF HARMONY UNANIMOUSLY RECOMMENDS THAT THE
SHAREHOLDERS VOTE FOR THE APPROVAL OF THE MERGER AGREEMENT.
 
    SHAREHOLDERS SHOULD NOT SEND THEIR STOCK CERTIFICATES WITH THEIR PROXY
CARDS.
 
    The cost of solicitation of the shareholders of Harmony will be paid by
Harmony. In addition to the solicitation of Proxies by use of mail, the
directors, officers or regular employees of Harmony may, but without
compensation other than their regular compensation, solicit proxies personally
or by telephone. Harmony intends to reimburse brokerage houses and other
custodians, nominees and fiduciaries for reasonable out-of-pocket expenses
incurred in forwarding copies of solicitation material to beneficial owners of
Harmony Common Stock held of record by such persons.
 
    All information in this Proxy Statement with respect to Culligan has been
furnished by Culligan, and all information with respect to Harmony has been
furnished by Harmony.
 
    The mailing of this Proxy Statement to shareholders of Harmony is expected
to commence on or about February 19, 1998.

    SET FORTH BELOW IS A BRIEF DESCRIPTION OF CERTAIN TERMS OF THE MERGER
AGREEMENT AND RELATED MATTERS. ALTHOUGH HARMONY'S MANAGEMENT BELIEVES THAT THIS
DESCRIPTION PROVIDES AN ADEQUATE DESCRIPTION OF THE MATERIAL PROVISIONS OF THE
MERGER AGREEMENT, THIS DESCRIPTION DOES NOT PURPORT TO BE COMPLETE AND IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE MERGER AGREEMENT, WHICH IS
ATTACHED HERETO AS APPENDIX A AND INCORPORATED HEREIN BY REFERENCE.
 
GENERAL
 
    Harmony, Culligan and Merger Sub have entered into the Merger Agreement,
which provides that Merger Sub will be merged with and into Harmony, with
Harmony becoming a wholly-owned Subsidiary of Culligan. Pursuant to the Merger,
each outstanding share of Harmony Common Stock, other than shares held by
shareholders who perfect dissenters' rights under Minnesota law, will be
converted at the Effective Time (as defined below) into the right to receive
$0.545 in cash. See "The Merger -- Conversion of Harmony Common Stock." As soon
as practicable after the conditions to consummation of the Merger described
below have been satisfied or waived and, unless the Merger Agreement has been
terminated as provided below, Articles of Merger will be filed with the
Secretary of State for the State of Minnesota, at which time the Merger will
become effective (the date on which the Merger becomes effective is referred to
herein as the "Effective Time"). It is currently contemplated that the Effective
Time will be as soon as practicable after the Special Meeting.
 
BACKGROUND OF THE MERGER
 
    During the first half of 1997, Harmony's Board of Directors considered the
strategic alternatives available to the Company, including potential
recapitalization transactions, as well as the viability of maintaining Harmony
as an independent entity. Harmony's management and Board of Directors believe
that Harmony's business could be developed further, but recognize that attaining
the desired growth would require a significant amount of time and a substantial
financial investment. Because Harmony is a small public company, the Board of
Directors believe that Harmony's value would not be reflected in the market
price of its Common Stock unless Harmony achieved substantially greater sales
and achieved significant profitability. As the purified water vending business
continues to grow, and as major players in the industry pursue consolidation, it
has become clear that the size and financial strength of Harmony's competitors
would hinder Harmony's ability to compete long-term in the marketplace and
achieve the required growth. Accordingly, the Company's Board of Directors
recognize that a sale of Harmony at an appropriate price would be in the best
interests of the Company's shareholders.
 
    During the third quarter of 1997, Harmony entered into discussions with
another water vending company regarding a possible merger. A term sheet was
agreed to, and the other party commenced its due diligence review of the
Company. Upon completion of its review, it withdrew from further discussions
with the Company.
 
    In September of 1997, Culligan initiated discussions with Harmony to
determine whether there might be a possible strategic relationship between
Culligan and Harmony. Representatives of Harmony's Board of Directors then met
with representatives of Culligan to discuss the acquisition of Harmony by
Culligan.
 
    In September of 1997, Culligan presented an offer to purchase all of the
outstanding shares of Harmony Common Stock for $0.55 per share. On September 25,
1997, the letter of intent was formally accepted by the Harmony Board of
Directors and executed on behalf of Harmony. The letter of intent included a
provision foreclosing Harmony from seeking or considering competing bids and
discussions, except as might be required in order for the Board to satisfy its
fiduciary obligations. Harmony agreed not to offer or participate in
negotiations, discussions or due diligence with any other party other than
Culligan until November 1, 1997. During the period between the approval of the
letter of intent and approval of the Merger Agreement by the Harmony Board,
Harmony did receive one other inquiry from another potential
 
                                       10
<PAGE>
investor, which party, after initial discussions with the Company, concluded
that it had no interest in pursuing a transaction.
 
    Following its due diligence, Culligan advised Harmony that certain matters
had come to its attention that, in its opinion, required an adjustment of the
consideration to $0.545 per share. The Harmony Board of Directors agreed to this
reduction in the purchase price per share.
 
    On December 24, 1997, the Harmony Board of Directors approved a form of the
Merger Agreement and authorized its officers to execute and deliver the Merger
Agreement in substantially that form. A definitive Merger Agreement was executed
between the parties as of January 12, 1998. On January 12, 1998, Harmony
publicly announced the signing of the Merger Agreement. Although prior to the
approval of the Merger Agreement, the Board of Directors of the Company did not
actively put the Company up for bid, it had engaged in discussions regarding
strategic transactions with several parties during 1997 and had received no
indications of interest from other potential purchasers other than as discussed
above. Accordingly, the Board of Directors of the Company, relying also on the
fairness opinion of Kinnard, believes that the proposed Merger provides the best
value to Harmony shareholders.
 
POSSIBLE CONFLICTS OF INTEREST
 
    Following the Merger, James C. Hawley, Harmony's President and Chief
Executive Officer, is expected to be employed by the surviving corporation in a
similar capacity. In connection with such continued employment, Mr. Hawley will
be entitled to receive certain benefits if his employment is voluntarily or
involuntarily terminated at any time prior to the first anniversary of the
consummation of the Merger. If Mr. Hawley is involuntarily terminated by the
surviving corporation within 12 months of the Effective Time, he will receive a
severance benefit equal to 12 months compensation.
 
    Although Harmony's existing officers are expected to continue serving as
officers of the corporation surviving the Merger, such officers have not and are
not expected to enter into employment agreements with Culligan or the surviving
corporation.
 
    Donald R. Brattain, the Company's Chairman of the Board, will enter into a
non-competition agreement, pursuant to which he will agree that for a period of
three years following consummation of the Merger, he will not engage in any
business competitive with the business of Harmony. In addition, Mr. Brattain
will execute and deliver an indemnification agreement indemnifying Culligan with
respect to damages resulting from any material breach of representations or
warranties made by the Company in the Merger Agreement. Mr. Brattain's exposure
under the indemnification agreement will not exceed $1,000,000. In addition, Mr.
Brattain has and will continue to provide bridge financing to Harmony up to the
date of the Special Meeting. Accordingly, the Company has agreed to provide Mr.
Brattain with compensation in the amount of $40,225 in connection with his
providing bridge financing, and the execution and delivery of the
non-competition agreement and the indemnification agreement, which consideration
will be paid to Mr. Brattain upon consummation of the Merger.
 
    The Merger Agreement also provides that, upon consummation of the Merger,
each unexpired, unexercised option to purchase Harmony Common Stock outstanding
and held by employees of the Company prior to the Merger (excluding options held
by non-employee directors), will entitle the holder to receive, for each share
of Harmony Common Stock subject to such option, $0.05 per share in cash. Under
this provision, Harmony's two executive officers will receive the following
consideration for their options.

HARMONY'S REASONS FOR THE MERGER; RECOMMENDATION OF THE HARMONY BOARD OF
  DIRECTORS
 
    The Harmony Board of Directors has unanimously approved the Merger
Agreement. The Harmony Board of Directors believes that the Merger is in the
best interests of Harmony shareholders and unanimously recommends that
shareholders vote FOR approval of the Merger Agreement. See "The Merger --
Conflicts of Interest." In reaching these conclusions, the Board of Directors
considered the following material factors, which were discussed at various
meetings of the Board during 1997. The Board considered the risks presented by
the competitive environment in the water vending marketplace. The Board also
recognized that the consideration offered to the shareholders in the Merger
represented a significant premium over the trading price of the Harmony Common
Stock immediately preceding announcement of the Merger Agreement. The Board of
Directors also considered the business, financial condition, results of
operations and prospects of Harmony on both an historical and prospective basis,
and the current and historical market prices of Harmony Common Stock, as well as
the opinion of Kinnard that the consideration to be received by shareholders of
Harmony in the Merger is fair to the shareholders from a financial point of
view. Although the Board approved the letter of intent subject to receipt of a
fairness opinion, its review of the final Merger Agreement was conducted with
full consideration of all relevant factors including the fairness opinion
delivered by Kinnard. See "The Merger -- Opinion of Investment Banker" and
"Stock Prices and Dividends."
 
    Further, the Board of Directors considered Culligan's ability to support and
supplement Harmony's management team with financial and other resources and to
provide Harmony with the advantages of a well-established, large-scale
distribution network. Minnesota law permits directors, in considering the best
interests of the corporation, to consider the interests of the corporation's
employees, customers and suppliers, as well as other non-financial
considerations. Consequently, the Board considered the foregoing factors as
important aspects of the fairness of the overall transaction.
 
OPINION OF INVESTMENT BANKER
 
    Harmony has retained John G. Kinnard & Co. ("Kinnard") to provide an opinion
to the Board of Directors as to the fairness of the consideration to be received
by the Harmony shareholders in connection with the Merger. Kinnard is an
investment banking firm and is engaged, in part, in mergers and acquisitions
advisory work and in valuations of businesses and securities.
 
    Kinnard was selected to evaluate the fairness of the consideration to be
received by the Harmony shareholders in conjunction with the Merger based, in
part, on previous investment banking services provided to Harmony by Kinnard.
Kinnard has, over the past six years, assisted Harmony in raising capital
through private and public offerings of the Company's common stock, including
the Company's initial public offering in 1993. Because of Kinnard's previous
contacts with Harmony and its understanding of Harmony's business, the Board of
Directors had confidence in Kinnard's ability to analyze the proposed Merger. In
addition, the Board concluded that Kinnard's bid with respect to the fairness
opinion was reasonable when compared to fees which might be charged by other
investment banking firms.
 
    Kinnard delivered its opinion to the Harmony Board of Directors on December
24, 1997, in connection with the Board's approval of the Merger Agreement.
Kinnard reaffirmed its opinion as of the date of the mailing of this Proxy
Statement.
 
    In arriving at its opinion, Kinnard:
 
     1. reviewed Harmony's annual reports, its reports on Form 10-KSB and
        related information for the three-year period ended December 31, 1996,
        and Harmony's reports on Form 10-QSB and related financial information
        for the first three quarters of 1997;
 
     2. reviewed certain information, including financial projections, related
        to the business, earnings, cash flow, assets and prospects of Harmony,
        as furnished by Harmony;
 
                                       12
<PAGE>
     3. conducted discussions with members of Harmony's senior management
        concerning Harmony's business, prospects and changes in Harmony's
        industry;
 
     4. visited the headquarters of Harmony in Eagan, Minnesota;
 
     5. conducted discussions with members of Culligan's senior management;
 
     6. reviewed published analysts' reports on the water processing,
        purification and vending industries;
 
     7. reviewed historical market prices and trading activity for Harmony
        Common Stock and compared such prices and activity to those of companies
        Kinnard deemed to be reasonably similar to Harmony;
 
     8. compared Harmony's results of operations to those of companies Kinnard
        deemed to be reasonably similar to Harmony;
 
     9. compared the proposed financial terms of the Merger with the financial
        terms, to the extent publicly available, of other mergers and
        acquisitions deemed by Kinnard to be relevant; and
 
    10. reviewed the Merger Agreement.
 
    In its review and analysis, and in preparing and formulating its opinion,
Kinnard assumed and relied upon the accuracy and completeness of all financial
and other information provided or otherwise made available to it (including
publicly available information), and Kinnard did not attempt to independently
verify any of such information. Kinnard assumed that the financial projections
provided to it were prepared in good faith and on a basis reflecting the best
currently available judgments and estimates of the management of Harmony.
Kinnard did not make or obtain an independent valuation or appraisal of the
assets or liabilities of Harmony. Kinnard's opinion is based on economic and
market conditions and other circumstances as they existed and could be evaluated
by it on the date of its opinion and on the date such opinion was reaffirmed.
Although Harmony's management believes that the financial and other information,
including projections, provided or otherwise made available to Kinnard was
accurate and complete in all material respects, if such information was
inaccurate or incomplete in any material respect, it is possible that Kinnard
might have come to a different conclusion as to the fairness of the Merger
consideration if it had been provided with accurate and complete information.
 
    No limitations were imposed by the Harmony Board upon Kinnard with respect
to the scope of the investigation made or the procedures followed by it in
rendering its opinion. Although Kinnard analyzed various alternative
transactions which may be available to Harmony, it was not authorized to and did
not solicit third party indications of interest for all or any part of Harmony
or its assets.
 
    The report presented by Kinnard to the Harmony Board on December 24, 1997 in
connection with its fairness opinion dated that date included the following
financial analyses with respect to Harmony:
 
        (i) comparable company analysis, which consisted of reviewing and
    considering financial and market data of Harmony and comparing that data
    with similar data for certain other publicly traded companies believed to be
    reasonably similar to Harmony;
 
        (ii) comparable transaction analysis, which consisted of reviewing
    purchase prices and financial terms of selected acquisitions involving
    companies in the water industry and public companies in general; and
 
       (iii) discounted cash flow analysis, which consisted of discounting to
    present value of projected future cash flows to shareholders of Harmony.
 
The report also included an analysis of the current trading prices of Harmony
Common Stock through December 18, 1997.
 
                                       13
<PAGE>
    In conducting the review and in performing the analyses described below,
Kinnard did not attribute any particular weight to any information or analysis
considered by it, but rather made qualitative judgments as to the significance
and relevance of each factor and analysis. Accordingly, Kinnard believes that
the information reviewed and the analysis conducted must be considered as a
whole and that considering any portion of such information or analyses, without
considering all of such information and analyses, could create a misleading or
incomplete view of the process underlying the opinion.
 
    COMPARABLE COMPANY ANALYSIS.  In performing the comparable Company analysis
for Harmony, Kinnard reviewed and compared the financial and market performance
of the following group of publicly traded water processing companies: Glacier
Water Services, Inc., Recovery Engineering, Inc., Great Pines Water Company,
Inc. and Water Point Systems Inc. (now defunct). Kinnard selected the Harmony
comparable companies on the basis of various characteristics, particularly lines
of business within the water processing industry. Kinnard considered certain
financial data of the comparable companies, including common stock prices, 1997
and 1998 projected earnings per share, price to earnings multiples, market
capitalization to revenue and operating income and total capitalization to
revenue and operating income.
 
    SELECTED MERGER AND ACQUISITION TRANSACTIONS.  Kinnard reviewed the terms of
selected mergers and acquisitions in the water industry, analyzing prices paid
relative to revenues, operating income and per vending machine. Kinnard also
discussed the acquisition premium, which is the amount by which the offer price
exceeds the market value of the acquired company's stock before the transaction
was publicly announced. This amount is typically expressed as a percentage of
the per share market value of the acquired company's shares. In connection with
analyzing acquisition premiums, Kinnard used industry sources which compile
information from hundreds of merger and acquisition transactions in various
industries. Kinnard submitted to the Harmony Board information stating that the
median acquisition premium on all public transactions has ranged from
approximately 27% to 35% over the past ten years. Culligan's offer of $0.545 per
share represents a premium of 58% over the midpoint of the bid and ask prices of
Harmony on December 18, 1997. Kinnard found Culligan's offer of $0.545 to be
fair relative to the prices paid in the selected merger and acquisition
transactions.
 
    DISCOUNTED CASH FLOW ANALYSIS.  Using a discounted cash flow to shareholders
analysis, Kinnard estimated the net present value of the future free cash flows
to shareholders that Harmony might be expected to produce over a five-year
period from 1998 through 2002, using projections provided by Harmony's
management, and assumptions relating to terminal values, if Harmony were to
perform on a stand-alone basis. The use of free cash flow multiples to determine
the terminal value resulted in a discounted cash flow reference range per share
of Harmony Common Stock of from $0.29 to $0.51. Analyzing the net present value
of future cash flows using net income multiples to determine the terminal value
resulted in a discounted cash flow reference range per share of Harmony Common
Stock of from $0.17 to $0.53.
 
    Harmony has agreed to pay Kinnard a fixed fee of $50,000 for its services in
connection with rendering its fairness opinion and has agreed to reimburse
Kinnard for its reasonable out-of-pocket expenses, including legal fees,
incurred in performing its services, and to indemnify Kinnard against certain
liabilities, including those arising under federal and state securities laws.
 
VOTE REQUIRED
 
    Approval of the Merger Agreement requires the affirmative vote of the
holders of a majority of the outstanding shares of Harmony Common Stock. Each
holder of Harmony Common Stock outstanding as of the Record Date is entitled to
one vote for each share held. On the Record Date, there were 8,045,161 shares of
Harmony Common Stock outstanding.
 
                                       14
<PAGE>
    Culligan, as the sole shareholder of Merger Sub, has approved the Merger
Agreement. Approval of the Merger Agreement by Culligan's shareholders is not
required under Minnesota or Delaware law and is not being sought.
 
CONVERSION OF HARMONY COMMON STOCK
 
    At the Effective Time, each share of Harmony Common Stock issued and
outstanding, exclusive of any shares of Harmony Common Stock held by holders who
have perfected their dissenters' rights under Minnesota Law (see "The Merger --
Rights of Dissenting Shareholders"), will be automatically converted into the
right to receive $0.545 in cash.
 
SURVIVING CORPORATION
 
    In the Merger, Merger Sub will be merged with and into Harmony, with Harmony
emerging as the surviving corporation and a wholly-owned subsidiary of Culligan.
At the Effective Time, the Articles of Incorporation of Merger Sub will serve as
the Articles of Incorporation of the surviving corporation until amended in
accordance with applicable law. The By-Laws of Merger Sub in effect at the
Effective Time shall be the By-Laws of the surviving corporation until amended
in accordance with applicable law.
 
SURRENDER OF CERTIFICATES FOR CASH
 
    Norwest Bank Minnesota, N.A., the Company's transfer agent, has been
designated as agent (the "Exchange Agent") for the holders of shares of Harmony
Common Stock to effect the exchange of stock certificates for cash. Culligan
will deposit with the Exchange Agent sufficient funds for the shares of Harmony
Common Stock which by virtue of the Merger are converted into and exchangeable
for cash as described above. The Exchange Agent will, as promptly as practicable
after the Effective Time, mail to all shareholders as of the Effective Time a
notice specifying the Effective Time of the Merger, accompanied by instructions
and a transmittal letter for the submission of stock certificates. HARMONY
SHAREHOLDERS ARE REQUESTED NOT TO SUBMIT THEIR STOCK CERTIFICATES UNTIL THEY
RECEIVE SUCH INSTRUCTIONS AND TRANSMITTAL LETTER.
 
    If any payment for shares of Harmony Common Stock is to be made in a name
other than that in which the shares surrendered for payment are registered on
the stock transfer books or other records of Harmony at the Effective Time, it
will be a condition for such payment that the certificates so surrendered shall
be properly endorsed or otherwise be in proper form for transfer and that the
person requesting such payment shall provide evidence that any applicable stock
transfer taxes have been paid.
 
    Each certificate which, prior to the Effective Time, represented outstanding
shares of Harmony Common Stock will, after the Effective Time, be deemed for all
purposes to evidence only the right to receive the amount of cash into which
such instruments shall have been converted by virtue of the Merger, except that
no conversion shall be made in respect of any share of Harmony Common Stock, the
holder of which is a "dissenting shareholder" who has (a) filed in the office of
the Secretary of Harmony, prior to the Special Meeting, a written objection to
the Merger and demand for payment, and (b) not voted in favor of the Merger. See
"Rights of Dissenting Shareholders" in this section. No interest will accrue or
be payable with respect to the amount payable in exchange for Harmony Common
Stock after the Effective Time or with respect to any funds held by the Exchange
Agent for the benefit of Harmony shareholders. During the six months following
the Effective Time, the Exchange Agent will pay to holders of Harmony Common
Stock (other than holders who have perfected their dissenter's rights under
Minnesota law), upon surrender of their certificates for shares (together with a
validly completed and duly executed transmittal letter in the form furnished by
the Exchange Agent) the amount in cash into which the shares of Common Stock
shall have been converted. After six months from the Effective Time,
shareholders must look to Harmony, as the surviving corporation in the Merger,
for such payment. Holders of Harmony Common Stock requesting payment from the
Company after six months from the Effective Time should send to Harmony a letter
requesting payment, which letter should include the holder's stock
certificate(s). Upon
 
                                       15
<PAGE>
receipt of such letter and certificate(s) and any other documentation and
information Harmony may request to verify the identity of the shareholder and
the validity of the certificate(s), Harmony will make the proper payments.
 
BUSINESS OF HARMONY PENDING THE MERGER
 
    Harmony has agreed that, prior to consummation of the Merger, unless
Culligan consents in writing, it will conduct its business in the regular course
and will use all reasonable efforts to preserve its business organization
intact. Harmony has further agreed that, unless consented to in writing by
Culligan, it will not amend its Articles of Incorporation or By-Laws, issue,
transfer, pledge, or sell, or authorize or oppose or agree to the issuance,
transfer, pledge or sale of any shares of its capital stock of any class, any
voting debt securities or other equity interests or any securities convertible
into, or any rights, warrants, calls, subscriptions, options or other rights or
agreements, commitments or understandings to acquire, any such shares, voting
debt securities, equity interests or convertible securities; acquire or agree to
acquire by merging or consolidating with, or by purchasing a substantial equity
interest in or substantial portion of the assets of, or by any other manner, any
business or any corporation, partnership, association, or other business
organization or division thereof or otherwise acquire or agree to acquire any
assets outside the ordinary and usual course of business consistent with past
practice, or otherwise enter into any material commitment or transaction outside
the ordinary and usual course of business consistent with past practice; sell,
lease, license, encumber or otherwise dispose of, or agree to sell, lease,
license, encumber or otherwise dispose of, any of its assets outside the usual
and ordinary course of business consistent with past practice; incur, assume,
pre-pay, guaranty, endorse or otherwise become liable or responsible (whether
directly, contingently or otherwise) for any indebtedness except pursuant to the
Company's existing outstanding lines of credit or in the ordinary and usual
course of business consistent with past practice; issue or sell any debt
securities or warrants or rights to acquire any debt securities of the Company
or guaranty any obligations of others; make any loans, advances or capital
contributions to, or investments in, any other person except in the ordinary and
usual course of business consistent with past practice; enter into, adopt, amend
or terminate any compensation or benefit plan or any agreement, arrangement,
plan or policy between the Company and one or more of its directors, officers or
employees; except in the ordinary course of business consistent with prior
practice, increase in any manner the compensation or fringe benefits of any
director, officer or employee or pay any benefit to any director, officer or
employee not required by any plan or arrangement as in effect as of the date of
the Merger Agreement or enter into any contract, agreement, commitment or
arrangement to do any of the foregoing or engage in any transaction with any
shareholder, officer or director except for certain scheduled transactions;
change any of its accounting principles, policies or procedures, except as may
be required by generally accepted accounting principles; take any action that
would or is reasonably likely to result in any of the conditions to the Merger
not being satisfied or that would materially impair the ability of the Company
to consummate the Merger in accordance with the terms of the Merger Agreement or
materially delay such consummation.
 
    Harmony has also agreed that it will not, directly or indirectly, through
any officer, director, agent or otherwise, initiate, solicit, encourage,
negotiate or discuss with any third party (including by way of furnishing
non-public information concerning the Company, its business or its assets or
properties), or take any other action to facilitate any inquiries with respect
to or the making of, any proposal that constitutes or may reasonably be expected
to lead to a merger, consolidation, business combination, sale of a significant
amount of assets outside the ordinary course of business, sale of shares of
capital stock outside the ordinary course of business, tender or exchange offer
or similar transaction involving the Company.
 
    During the period prior to the Effective Time, Harmony has agreed to afford
Culligan and its representatives reasonable access to Harmony's properties,
books and records, and all other information concerning the business, properties
and personnel of the Company as Culligan may reasonably request. Both Harmony
and Culligan have agreed to execute and deliver such instruments and take such
other
 
                                       16

action as may reasonable be required in order to carry out the Merger Agreement

    (b) by either Culligan or Harmony if the Merger shall not have been
       consummated before March 15, 1998 (unless the failure to so consummate

       Culligan and the representations, warranties or covenants or Culligan set
       forth in the Merger Agreement, or any material failure on the part of
       Culligan to comply with its obligations thereunder, or (ii) the Company's
       shareholders do not approve of the Merger Agreement at the Special
       Meeting.
 
    Upon termination of the Merger Agreement by either Harmony or Culligan, the
Merger Agreement shall forthwith become void and there shall be no liability or
obligation on the part of Culligan, Merger Sub, Harmony or their respective
affiliates, officers or directors, except as described below under "The Merger
- -- Expenses and Fees" and except as to the obligation of Culligan to maintain
the confidentiality of information provided by Harmony in connection with
Culligan's evaluation of Harmony.
 
DEREGISTRATION OF HARMONY COMMON STOCK
 
    If the Merger is consummated, the conditions for terminating registration of
the Harmony Common Stock under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), will be met. Accordingly, upon consummation of the Merger,
Harmony will terminate registration of the Harmony Common Stock under the
Exchange Act and cause the Harmony Common Stock to cease to be authorized for
quotation on The Nasdaq SmallCap Market.
 
EXPENSES AND FEES
 
    Except as described in the following sentences, whether or not the Merger is
consummated, all costs, fees and expenses incurred in connection with the Merger
(including, but not limited to, accounting, legal and investment banking fees)
and the transactions contemplated by the Merger Agreement will be paid by the
party incurring such costs, fees and expenses; provided, that upon consummation
of the Merger, Culligan shall cause the surviving corporation to pay all
reasonable fees, costs and expenses of Harmony incurred in connection with the
Merger Agreement and the transactions contemplated thereby.
 
    So long as Culligan shall not have materially breached its obligations under
the Merger Agreement, Harmony will be obligated to pay Culligan the sum of
$500,000 if, within twelve months following termination of the Merger Agreement
as a result of (i) the failure of the Company's shareholders to approve the
Merger Agreement at the Special Meeting, or (ii) the withdrawal, amendment or
modification by the Board of Directors of the Company, in a manner adverse to
Culligan, its favorable recommendation of the Merger Agreement, and Harmony
shall enter into an agreement, arrangement or understanding providing for the
sale or other disposition of the business of the Company, or a Competing
Transaction (as defined in the Merger Agreement). In the event of a termination
of the Merger Agreement for the reasons described above, Harmony will also be
obligated to pay the reasonable out-of-pocket expenses incurred by Culligan in
connection with the Merger within two business days after receipt from Culligan
of a statement of such expenses.
 
                                       18

ACCOUNTING TREATMENT
 
    The Merger will be accounted for as a "purchase" as such term is used under
generally accepted accounting principles.
 
FEDERAL INCOME TAX CONSEQUENCES
 
    The following general description of the federal income tax consequences of
the Merger does not take into account the facts and circumstances of any
particular shareholder of Harmony. Each Harmony shareholder should consult his
or her tax advisor about the specific tax consequences to him or her of the
proposed transactions, including the application and effect of state, local,
foreign and other tax laws.
 
    Shareholders will recognize gain or loss for federal income tax purposes
measured by the difference between the tax basis of their shares and the cash
received therefor. Such gain or loss will be treated as a capital gain or loss
if the Harmony Common Stock exchanged for cash was held as a capital asset at
the Effective Time. The receipt of cash pursuant to the exercise of dissenters'
rights with respect to the Merger will be a taxable transaction to shareholders
receiving such cash, and a dissenting shareholder will recognize gain or loss
measured by the difference between the cash so received and such shareholder's
tax basis in the Harmony Common Stock exchanged therefor. Such gain or loss will
be treated as a capital gain or loss if such shares are held as a capital asset
at the Effective Time.
 
    THE FEDERAL INCOME TAX DISCUSSION IN THIS PROXY STATEMENT IS BASED UPON
CURRENT LAW AND IS INTENDED FOR GENERAL INFORMATION ONLY. EACH SHAREHOLDER IS
URGED TO CONSULT HIS OR HER OWN TAX ADVISOR CONCERNING THE SPECIFIC TAX
CONSEQUENCES OF THE MERGER TO SUCH SHAREHOLDER, INCLUDING THE APPLICABILITY AND
EFFECT OF STATE, LOCAL AND OTHER TAX LAWS.
 
REGULATORY APPROVALS
 
    Harmony is not aware of any governmental approvals or actions that are
required for the consummation of the Merger. Should any such approvals or
actions be required, it is currently contemplated that such approvals or actions
would be sought, but there can be no assurance that such approvals, if any,
would be received.
 
RIGHTS OF DISSENTING SHAREHOLDERS
 
    Although Harmony's management believes that the following discussion of the
law pertaining to dissenter's rights under the Minnesota Business Corporation
Act (the "MBCA") provides an accurate description of the material provisions of
such law, such discussion does not purport to be complete and is qualified in
its entirety by reference to the full text of Sections 302A.471 and 302A.473 of
the MBCA attached to this Proxy Statement as a Appendix B. Any shareholder of
Harmony who wishes to exercise such dissenters' rights or who wishes to preserve
his or her right to do so should review the following discussion and Appendix B
carefully, because failure to comply timely and properly with the procedures
specified will result in the loss of dissenters' rights in connection with the
Merger.
 
    PROCEDURES TO PRESERVE DISSENTERS' RIGHTS.  Under Minnesota law, any holder
of Harmony Common Stock who follows the procedures set forth in Section 302A.473
of the MBCA will be entitled to receive payment in cash of the "fair value" of
such shareholder's shares. As used in Section 302A.473, the "fair value of the
shares" means the value of the shares of Harmony immediately before the
Effective Date of the Merger.
 
    The Merger Agreement must be approved by the holders of a majority of the
outstanding shares of Common Stock of Harmony.
 
                                       19
<PAGE>
    Under Section 302A.473 of the MBCA, if a corporation calls a shareholder
meeting at which a plan of merger to which such corporation is a party is to be
voted upon, the notice of the meeting must inform each shareholder of the right
to dissent and must include a copy of Section 302A.471 and Section 302A.473 of
the MBCA and a brief description of the procedure to be followed under such
sections. This Proxy Statement constitutes such notice to the shareholders of
Harmony, and the applicable statutory provisions of the MBCA are attached to
this Proxy Statement as a Appendix B.
 
    A shareholder who wishes to exercise dissenters' rights must file with
Harmony, before the vote on the Merger Agreement, a written notice of intent to
demand the fair value of the shares owned by such shareholder and must not vote
his or her shares in favor of the Merger Agreement. A vote against the Merger
Agreement will not in itself constitute such a written notice, and a failure to
vote will not affect the validity of a timely written notice. However, the
submission of a blank Proxy will constitute a vote in favor of the Merger
Agreement and a waiver of statutory dissenters' rights.
 
    The written notice should be executed by or on behalf of the holder of
record fully and correctly, as the holder's name appears on the holder's stock
certificates. If the shares of Harmony Common Stock are owned of record in a
fiduciary capacity, such as by a trustee, guardian, or custodian, execution of
the written notice should be made in that capacity. If the shares of Harmony
Common Stock are owned of record by a corporation or other organization, the
written notice must be executed by a duly authorized legal representative, such
as an officer. If the shares of Harmony Common Stock are owned of record by more
than one person, as in a joint tenancy or tenancy in common, the notice should
be executed by or on behalf of all joint owners. An authorized agent, including
one or more joint owners, may execute a written notice on behalf of a holder of
record; however, the agent must identify the record owner or owners and, in
executing the written notice, must expressly disclose that the agent is agent
for such owner or owners.
 
    All written notices should be sent or delivered to Nancy A. Quam, Corporate
Secretary, 601 Lakeshore Parkway, Suite 1140, Minneapolis, Minnesota 55305, so
as to be received prior to the vote on the Merger Agreement.
 
    After the Merger Agreement has been approved by the shareholders of Harmony,
Harmony must send a written notice to all shareholders who have filed with
Harmony before the vote on the Merger Agreement a written notice of intent to
demand the fair value of the shares owned by such shareholder and have not voted
their shares in favor of the Merger Agreement. The notice from Harmony must
contain:
 
    (1) the address to which a demand for payment and stock certificates must be
       sent in order to obtain payment and the date by which they must be
       received;
 
    (2) a form to be used to certify the date on which the shareholder, or the
       beneficial owner on whose behalf the shareholder dissents, acquired the
       shares or an interest in them and to demand payment; and
 
    (3) a copy of Sections 302A.471 and 302A.473 of the MBCA and a brief
       description of the procedures to be followed under such sections.
 
    In order to receive the fair value of the shares, a dissenting shareholder
must demand payment and deposit his shares within 30 days after the
above-described written notice is given, but the dissenter retains all other
rights of a shareholder until the Merger takes effect.
 
    A shareholder may not assert dissenters' rights as to less than all of the
shares registered in the name of the shareholder. However, a record owner, such
as a broker who holds shares of Harmony Common Stock as a nominee for several
beneficial owners, may exercise dissenters' rights with respect to all of the
shares of Harmony Common Stock held for one or more beneficial owners while not
exercising such rights with respect to the shares of Harmony Common Stock held
for other beneficial owners. In such case, the written notice of intent to
demand the fair value of the shares of Harmony Common Stock must disclose the
name and address of each beneficial owner on whose behalf the shareholder
dissents and the number
 
                                       20
<PAGE>
of shares of Harmony Common Stock beneficially owned by each. In that event, the
rights of the dissenter will be determined as if the shares as to which the
shareholder has dissented and the other shares were registered in the names of
different shareholders. If no such information is provided, the written notice
will be presumed to cover all shares of Harmony Common Stock held in the name of
the record owner.
 
    A person who is the beneficial owner of shares of Harmony Common Stock held
in a brokerage account or other nominee form and who wishes to exercise
dissenters' rights must take all necessary steps in order that a written notice
is timely filed by the record holder of such shares. Alternatively, such
beneficial owner may assert dissenters' rights with respect to shares held on
his or her behalf and will be treated as a dissenting shareholder under the
terms of Sections 302A.471 and 302A.473, if the beneficial owner submits a
signed written consent of the record holder to Harmony at the time of or before
the assertion of such rights. The written consent of the record holder will
serve to verify the beneficial owner's entitlement and allow the record holder
to protect any security interest in the shares.
 
    Beneficial owners of Harmony Common Stock are urged to consult with their
brokers to determine the appropriate procedures for asserting dissenters'
rights.
 
    PROCEDURES FOLLOWING AN ASSERTION OF DISSENTERS' RIGHTS.  After the
Effective Date, or after Harmony receives a valid demand for payment, whichever
is later, Harmony must remit to each dissenting shareholder who has not voted
his or her shares in favor of the Merger Agreement and has filed with Harmony
before the vote on the Merger Agreement a written notice of intent to demand the
fair value of the shares owned by such shareholder and who has demanded payment
and deposited his or her shares, the amount Harmony estimates to be the fair
value of the shares, plus interest ("interest" commences five days after the
Effective Date up to and including the date of payment, calculated at a rate
provided under Minnesota law for interest on verdicts and judgments),
accompanied by:
 
    (1) Harmony's closing balance sheet and statement of income for a fiscal
       year ended not more than 16 months before the Effective Date of the
       Merger, together with the latest available interim financial statements;
 
    (2) An estimate by Harmony of the fair value of the shares and a brief
       description of the method used to reach the estimate; and
 
    (3) A copy of Sections 302A.471 and 302A.473 of the MBCA, and a brief
       description of the procedure to be followed in demanding supplemental
       payment.
 
    Harmony may withhold the above-described remittance from a person who was
not a shareholder on the date the Merger Agreement was first announced to the
public or who is dissenting on behalf of a person who was not a beneficial owner
on that date. If the dissenter has not voted his or her shares in favor of the
Merger Agreement and has filed with Harmony before the vote on the Merger
Agreement a written notice of intent to demand the fair value of the shares
owned by such shareholder, Harmony must forward to such dissenter the materials
described in the preceding paragraph, a statement of the reason for withholding
the remittance, and an offer to pay to the dissenter the amount listed in the
materials if the dissenter agrees to accept that amount in full satisfaction.
The dissenter may decline the offer and demand payment of the dissenter's own
estimate of the fair market value of the shares, plus interest, by written
notice to Harmony. Failure to do so entitles the dissenter only to the amount
offered. If the dissenter makes demand, the procedures, costs, fees and expenses
described below for petitioning the court shall apply.
 
    If Harmony fails to remit payment within 60 days of the deposit of
certificates, it must return all deposited certificates and cancel all transfer
restrictions. However, Harmony may require a deposit or restrict transfer at a
later time and again give notice that contains:
 
    (1) The address to which a demand for payment and certificates of
       certificated shares must be sent in order to obtain payment and the date
       by which they must be received;
 
                                       21
<PAGE>
    (2) A form to be used to certify the date on which the shareholder, or the
       beneficial owner on whose behalf the shareholder dissents, acquired the
       shares or an interest in them and to demand payment; and
 
    (3) A copy of Sections 302A.471 and 302A.473 of the MBCA and a brief
       description of the procedures to be followed under such sections.
 
    If a dissenter believes that the amount remitted by Harmony is less than the
fair value of the shares, plus interest, the dissenter may give written notice
to Harmony of the dissenter's own estimate of the fair value of shares, plus
interest, within 30 days after Harmony mails the remittance, and demand payment
of the difference (a "Demand"). Otherwise, a dissenter is entitled only to the
amount remitted by Harmony.
 
    If Harmony receives a Demand, it must, within 60 days after receiving the
Demand, either pay to the dissenter the amount demanded or agreed to by the
dissenter after discussion with Harmony or file in the appropriate court a
petition requesting that the court determine the fair value of the shares, plus
interest. The petition must name as parties all dissenters who made a Demand for
payment and who have not reached agreement with Harmony. The jurisdiction of the
court is plenary and exclusive. The court may appoint appraisers, with powers
and authorities the court deems proper, to receive evidence on and recommend the
amount of the fair value of the shares. The court must determine whether the
shareholder or shareholders in question have fully complied with the
requirements of Section 302A.473 of the MBCA and must determine the fair value
of the shares, taking into account any and all factors the court finds relevant,
computed by any method or combination of methods that the court, in its
discretion, sees fit to use, whether or not used by Harmony or by a dissenter.
The fair value of the shares as determined by the court is binding on all
shareholders, wherever located. A dissenter is entitled to judgment for the
amount by which the fair value of the shares as determined by the court, plus
interest, exceeds the amount, if any, remitted by Harmony, but shall not be
liable to Harmony for the amount, if any, by which the amount, if any, remitted
to the dissenter exceeds the fair value of the shares as determined by the
court, plus interest.
 
    The court must determine the costs and expenses of any appraisers in a
proceeding under the preceding paragraph, including the reasonable expenses and
compensation of any appraisers appointed by the court, and must assess these
costs and expenses against Harmony, except that the court may assess part or all
of those costs and expenses against a dissenter whose demand is found to be
arbitrary, vexatious, or not in good faith.
 
    If the court finds that Harmony has failed to comply substantially with
Section 302A.473 of the MBCA, the court may assess all fees and expenses of any
experts or attorneys as the court deems equitable. These fees and expenses may
also be assessed against a person who has acted arbitrarily, vexatiously, or not
in good faith in bringing the proceeding and may be awarded to a party injured
by those actions.
 
    The court may award, in its discretion, fees and expenses to an attorney for
the dissenters out of the amount awarded to the dissenters, if any.
 
    FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTIONS 302A.471 AND 302A.473 OF
THE MBCA FOR PERFECTING DISSENTERS' RIGHTS MAY RESULT IN THE LOSS OF THOSE
RIGHTS.
 
TRANSACTIONS BETWEEN HARMONY AND CULLIGAN
 
    Prior to the negotiation, execution and delivery of the Merger Agreement,
there have been no business transactions between Harmony and Culligan.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    The following discussion should be read in conjunction with Harmony's
consolidated financial statements and the notes thereto appearing elsewhere in
this Proxy Statement.
 
RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS -- FIRST NINE MONTHS (1997)
 
REVENUES
 
    For the first nine months of 1997, revenues were $6,631,000, an increase of
six percent over revenues of $6,277,000 reported for the first nine months of
1996.
 
    For the first nine months of 1997, contracted revenue sharing sales were
$4,705,000 compared to $4,527,000 for the first nine months of 1996, an increase
of four percent. These revenue increases represented an increase in the number
of gallons of treated water sold by the Company. The increase in the number of
gallons of treated water sold is driven both by the increase in the number of
customer locations for the Company's installed Harmony Brook-Registered
Trademark- Premium Drinking Water systems and the increase in volume at existing
customer locations. At September 30, 1997, the Company had 1,617 domestic
customer locations installed, compared with 1,561 at September 30, 1996. In
addition, the Company had 110 customer locations installed in Mexico at
September 30, 1997 compared with 104 customer locations at September 30, 1996.
The total customer locations at September 30, 1997 was 1,727 compared with 1,665
customer locations at September 30, 1996, a four percent increase. Domestic
revenues for customer locations in place at both September 30, 1997 and 1996
grew five percent in the first nine months, while retail gallons dispensed
increased seven percent. Growth rates for the Company's number of customer
locations, dispenser revenues and gallons dispensed continued to be affected by
instances of account turnover and price concessions near the end of 1996 and
start of 1997, which resulted from increased competition in the Company's core
Midwest markets.
 
    Bottle sales increased 12 percent for the first nine months of 1997 to
$1,714,000 compared to $1,529,000 in the first nine months of 1996. Bottle sales
are recognized from two different classes of customers: those customers who
purchase bottles in conjunction with having one of the Company's Harmony
Brook-Registered Trademark- Premium Drinking Water systems installed (Premium
Bottle Sales) and all other customers who purchase bottles typically on a
wholesale basis (Wholesale Bottle Sales). Premium Bottle Sales decreased one
percent both in the comparable third quarters, from $336,000 in 1996 to $332,000
in 1997, and in the first nine months, from $849,000 in 1996 to $844,000 in
1997. The slight third quarter and nine month decrease in Premium Bottle Sales
is a result of certain routes being open at times due to employee turnover.
Wholesale Bottle Sales increased 28 percent in the comparable first nine months,
from $680,000 in 1996 to $870,000 in 1997. The increases in Wholesale Bottles
sales were a result of continued emphasis on rebuilding and growing this
business segment.
 
    Equipment sales, while contributing incremental revenue, continue to be a
lower priority for the Company. Management does not expect a significant
contribution from equipment sales for the full year 1997 or 1998.
 
GROSS MARGIN
 
    For the first nine months, the Company's total gross margin was 51 percent
of revenues for l997 compared with 54 percent of revenues for 1996. These
decrease reflects primarily the impact of price competition, costs related to
increased product quality testing and equipment refurbishment in the Company's
core business segment, contracted revenue sharing. This refurbishment activity
results in a significant portion of the cost being expensed to the income
statement but does conserve cash when compared to building new equipment for new
customer locations.
 
                                       23
<PAGE>
    The gross margin for contracted revenue sharing for the first nine months of
1997 was 58 percent of related revenues. The comparable gross margin for 1996
was 62 percent of related revenues for the first nine months. This decrease was
related to the same three factors cited above.
 
    The gross margin for bottle sales was 33 percent of related revenues in the
first nine months of 1997. This margin compares to 33 percent of related
revenues in the first nine months of 1996. Gross margins on bottle sales vary
depending on the style and quantities of bottles sold.
 
    For the first nine months of 1996 and 1997 the gross margin for equipment
sales was 26 percent of related revenues. The margins for equipment sales
reflect the mix of sales between complete systems sold (typically a lower
margin) versus sales of service parts (typically a higher margin).
 
EXPENSES
 
    For the first nine months of 1997 and 1996 field office expenses were
$1,932,000 and $1,947,000, respectively, a decrease of one percent. Compensation
expense decreased due to employee turnover, but this decrease was offset by
increased vehicle expenses for the first nine months of 1997 due to the
Company's aging fleet. No new geographic territories were entered for all
periods presented, although two service routes were added in existing
territories in the first half of 1997.
 
    For the first nine months of 1997 corporate S,G & A expenses were $1,253,000
compared to $1,220,000 in the first nine months of 1996, a three percent
increase. This increase in the first nine months of 1997 is primarily
attributable to increased Mexican subsidiary expenses related to added personnel
to support its growth and a high inflation environment.
 
OPERATING AND NET INCOME (LOSS)
 
    Operating income was reported for all periods presented. Other expense, the
only line item between operating income and net income (loss), consisted
primarily of net interest expense for all interim periods presented. A net loss
is reported for both the first nine months of 1996 and 1997.
 
MEXICAN SUBSIDIARY
 
    All of the interim financial information included in this Proxy Statement
reflects the results and balances of the Company's Mexican Subsidiary unless
explicitly stated otherwise. The following table summarizes the Company's
Mexican Subsidiary results of operations in U.S. Dollars for the interim periods
presented and the percentage change. The Company does not allocate charges for
financing or corporate administrative support services to Mexico.

LIQUIDITY AND CAPITAL RESOURCES
 
    In the first nine months of 1997, the Company had $697,000 of net cash
provided by operating activities compared to $739,000 of net cash provided by
operating activities in the first nine months of 1996. The primary decrease in
net cash provided by operating activities for the first nine months of 1997 was
an increase in accounts receivable. The increase in accounts receivable for the
first nine months was
 
                                       24
<PAGE>
offset by an increase in accounts payable. Cumulative changes in all other
operating activity areas were small compared to the changes in accounts
receivable and accounts payable for all periods presented.
 
    For the first nine months of 1997 and 1996, the Company invested $982,000
and 964,000, respectively, in property and equipment, an increase of two
percent. The first nine months of 1996 included a $135,000 buy-out of leased
equipment. After adjusting for this lease buy-out in the first nine months of
1996, the remaining investment in property and equipment for all periods
presented consisted primarily of the manufacture of new Harmony Brook-Registered
Trademark- Premium Drinking Water systems and the refurbishment of existing
systems. The increase in investment in property and equipment is primarily
driven by the capitalized portion of refurbishment of the Company's older
systems.
 
    On February 18, 1997, the Company and its principal lender amended and
restated the Company's term loan agreement. The agreement combined both
outstanding term loans into one term loan facility to be repaid in equal monthly
principal installments plus accrued interest with a final principal payment plus
accrued interest due in February 2000. The amended term loan bears interest at
the bank's reference rate plus 3.75 percent. In addition, the bank received a
fee of $15,000.
 
    As part of the amended and restated term loan agreement, the principal
lender required the Company to raise at least $1,000,000 by March 1, 1997 with
30 percent of the gross proceeds to be specifically applied to the principal
balance of outstanding bank debt. In February 1997, the Company negotiated a
private placement of $1,000,000 of subordinated notes with shareholders and
accredited investors. The notes bear interest at 14 percent, payable monthly and
are due March 2000. In addition, warrants were issued in connection with the
notes at the rate of one warrant for each $5.00 of subordinated debt. The notes
are collateralized by a lien on all the Company's assets, subordinate to the
interests of the Company's two senior lenders.
 
    On July 31, 1997, the Company entered into an agreement with a shareholder
and board member for the sale/leaseback of dispensing equipment; this was the
second such agreement in the first nine months of 1997.
 
    The Company required additional capital during the fourth quarter of 1997
and management estimates that under its current operating plan it will require
additional capital during calendar 1998. As of the date of this Proxy Statement,
the Company had obtained bridge financing in the amount of $50,000 from the
Chairman of its Board of Directors. Projections also indicate that, upon closing
its books, the Company expects to determine that during the fourth quarter of
1997 it will probably have violated certain financial covenants contained in the
loan agreement with its principal bank lender. The Company has obtained
agreements from its two senior lenders to suspend principal payments due in
November 1997 through February 1998. If the Merger is consummated, management
expects that the surviving corporation will receive the necessary additional
capital from Culligan. Management also expects that financial covenant
violations and other issues relating to the payment of principal and interest to
the Company's senior lenders will be resolved by the surviving corporation with
the assistance of Culligan shortly after consummation of the Merger.
 
    In the event Harmony's shareholders do not approve the Merger Agreement at
the Special Meeting, the Company will have to obtain additional capital
immediately. Management is currently uncertain about its ability to obtain the
necessary capital should the Merger Agreement be terminated, and there can be no
assurance that such capital, if available, can be obtained on terms acceptable
to the Company or its shareholders (See Note 2 to the Audited Consolidated
Financial Statements).
 
EARNINGS PER SHARE
 
    Statement of Financial Accounting Standards (SFAS) No. 28, EARNINGS PER
SHARE, is effective for the Company for the periods ending after December 15,
1997. The Company expects no material impact from
 
                                       25

the adoption of this financial standard. The basic earnings per share
computation, as defined by SFAS No. 128, applied to all periods presented would
yield the same result that is currently reported herein.

REVENUES
 
    Total revenues are realized from contracted revenue sharing, bottle sales,
and equipment sales.
 
    Contracted revenue sharing consists of revenues derived from the sale of
treated water by the gallon to supermarkets or other retail operators, who sell
the water to the public or use the water themselves. Revenues from contracted
revenue sharing have grown primarily as a result of the Company's system removal
and relocation program and secondly as a result of the increase in the number of
customer locations under contract. The weighted average number of customer
locations during 1996 was 1,521, an increase of two percent from the 1995
weighted average of 1,489. These customer locations produced average annualized
contracted revenue sharing of $3,588 per location, an increase of six percent
from the 1995 annualized revenue per location of $3,386.
 
    The Company's domestic customers increased three percent from 1,528 at the
end of 1995 to 1,574 at the end of 1996. Behind this net increase of 46
customers, the Company actually removed 207 customer locations and installed 253
new customer locations during 1996. Of the 207 systems removed during 1996, 34
were from a supermarket chain that closed or sold substantially all of its West
Coast locations, 24 were from a Midwest division of a supermarket chain that was
lost to a competitor in late 1996, leaving 149
 
                                       26
<PAGE>
systems which were primarily removed at the Company's discretion due to poor
return on investment. Systems that are removed are refurbished, if needed, and
then reinstalled in locations based on retailer demand, volume potential and fit
to established routes.
 
    Domestic customer locations that were installed for all of 1995 and 1996
grew seven percent in dollars and 12 percent in gallons for dispenser gallons
only. The primary difference between the dollar growth and dispensed gallons
growth is price concessions given to customers as a direct result of
competition. One regional competitor in the Midwest has competed for the
Company's customers using lower pricing as its primary selling point. While the
Company believes competition on the basis of providing superior service and
overall value is the appropriate long-term strategy, future potential price
concessions coupled with the potential for other competitors with greater
financial resources to enter the Company's markets could adversely effect the
Company's future operating results and financial position.
 
    Revenues from bottle sales are a composite of field bottle sales and
wholesale bottle sales. Field bottle sales increased 12 percent from $992,000 in
1995 to $1,109,000 in 1996. This increase is due to the increase in the number
of contracted revenue sharing customer locations to which field bottle sales are
made, coupled with a continuing emphasis placed on this product line by
management as a catalyst for increased contracted revenue sharing sales volume.
Wholesale bottle sales increased three percent from $794,000 in 1995 to $816,000
in 1996. This increase is attributable primarily to the Company's efforts to
rebuild its wholesale bottle customer base.
 
    Equipment sales consist primarily of revenues from the sale of Harmony
Brook-Registered Trademark- Premium Drinking Water systems to third party
dealers, both domestic and international. Revenues increased slightly in 1996
from this segment without an increase in resources devoted to generating these
revenues.
 
GROSS MARGINS
 
    The Company's total gross margin for 1996 increased nearly one percentage
point over 1995. This increase is due to better management of costs associated
with both bottle and equipment sales.
 
    Contracted revenue sharing gross margin, as a percent of sales, decreased
due primarily to the cost of certain refurbishments performed on removed systems
during 1996. The gross margin percent on bottle sales increased slightly due to
a shift in product mix towards larger containers that yield a higher margin.
Gross margin on equipment sales increased due primarily to a small price
increase combined with a reduction in manufacturing overhead costs in 1996.
 
EXPENSES
 
    Field office selling, general and administrative expenses increased three
percent in 1996, significantly less than the percentage increase in overall
revenue. This increase is due primarily to the addition of staff to service
major chain customers in the Midwest. The Company's primary focus for 1997
continues to consist of increasing market penetration in its existing geographic
territories versus development of new geographic territories.
 
    Corporate selling, general and administrative costs increased slightly
during 1996 due to added administrative staff in Mexico. This slight increase
continues to reflect the Company's efforts to control its discretionary
spending.
 
    The Company's operating expenses for 1995 included one-time charges of
$193,000 related to officer severance and other special charges reflecting
changes in certain business strategies. Also in 1995, the Company recorded a
charge of $123,000 related to an uncollectible receivable from its largest
wholesale bottle customer. These charges totaled $316,000, or $0.06 per share.
 
                                       27
<PAGE>
OPERATING INCOME AND NET LOSS
 
    The Company recorded its first full year of operating income in 1996.
Operating income increased $884,000 from a 1995 operating loss of $734,000 to
1996 operating income of $150,000. This increase of $884,000 compares to an
increase of $1,141,000 in sales resulting in an incremental margin of 77
percent. Taking into account the one-time and special charges of $316,000 in
1995, the comparable operating income increase would be $568,000 with an
incremental margin of 50 percent.
 
    The net loss for 1996 is the difference between operating income and the
other income and expenses, which consists primarily of interest expense.

REVENUES
 
    Revenues from contracted revenue sharing grew as a result of the increase in
the number of customer locations under contract. The weighted average number of
customer locations during 1995 was 1,489, an increase of 26 percent from the
1994 weighted average of 1,185. These customer locations produced average
annualized contracted revenue sharing of $3,386 per location, an increase of 11
percent from the 1994 annualized revenue per location of $3,047.
 
    Revenues from bottle sales declined in 1995. Field bottle sales increased 31
percent from $727,000 in 1994 to $954,000 in 1995. This increase was due to the
increase in the number of contracted revenue sharing customer locations to which
field bottle sales are made coupled with a continued emphasis placed
 
                                       28
<PAGE>
on this product line by management as a catalyst for increased contracted
revenue sharing sales volume. Wholesale bottle sales decreased 45 percent from
$1,500,000 in 1994 to $833,000 in 1995. This decrease was attributable primarily
to the loss of the Company's largest wholesale bottle customer in early 1995 due
to that customer's insolvency, as well as to a slowing down of the purchasing
activity of the larger remaining customers.
 
GROSS MARGINS
 
    The Company's total gross margin for 1995 increased four percentage points
over 1994. This increase was essentially due to higher contracted revenue
sharing revenues in comparison to total revenues. The gross margin increase on
contracted revenue sharing resulted from the higher number of customer
installations in place during 1995, which improved the Company's ability to
cover its fixed costs related to this portion of its revenues.
 
    The gross margin on bottle sales increased slightly due to a shift in
product mix towards larger containers that yield a higher margin. Gross margin
on equipment sales decreased due to lower production levels in 1995, which
resulted in greater fixed overhead costs being allocated to each unit produced.
 
EXPENSES
 
    The Company's operating expenses for 1995 included one-time charges of
$193,000 related to officer severance and other special charges reflecting
changes in certain business strategies. Also in 1995, the Company recorded a
charge of $123,000 related to an uncollectible receivable from its largest
wholesale bottle customer. These charges totaled $316,000, or $0.06 per share.
 
    Field office selling, general and administrative expenses increased faster
than overall revenue, but slightly slower than contracted revenue sharing
revenues. This increase was primarily due to a full year's effect of the
Company's extensive geographic expansion that occurred throughout 1994. Also
contributing to this increase was a full year of operations in 1995 from both
the wholesale bottle segment plus the Company's wholly owned Mexican subsidiary.
 
    Corporate selling, general and administrative costs increased at less than
half the rate of field office selling, general and administrative expenses,
reflecting the Company's efforts to control its discretionary spending.
 
OPERATING AND NET LOSS
 
    The Company's operating loss increased from 1994 to 1995 primarily due to
the one-time special charges, the uncollectible receivable write-off, the
decline in wholesale bottle sales and the increase in field office selling,
general and administrative expenses. Excluding the one-time special charges and
the uncollectible receivable write-off from 1995's operating loss results in an
adjusted operating loss of $418,000 compared to $329,000 in 1994, a 27 percent
increase.
 
    Other expense consisted of interest expense which increased significantly
due to increased debt financing of the Company's growth.

    Mexican operations began in early 1994. At year-end 1994, the subsidiary had
60 units installed with most of these installations occurring in the last half
of the year. At the end of 1995, the Company had 85 total units installed, an
increase of 42 percent over year-end 1994. At the end of 1996, the Mexican
subsidiary had 107 customer locations installed, an increase over year-end 1995
of 26 percent.
 
    Although the Company believes that potential exists for profitable growth in
the Mexican market, the devaluation of the Mexican New Peso, which began in
December 1994, and the resulting adverse economic conditions that occurred
throughout 1995 and 1996 have caused management to re-evaluate its strategy for
Mexican growth. Management does not intend to provide a significant amount of
additional equipment to the Mexican subsidiary for the foreseeable future due
primarily to limited capital resources, but also due to the unstable conditions
existing in the Mexican economy. In addition, one of the Company's senior
lenders has negotiated a restrictive covenant with the Company limiting the
amount of equipment that can be supplied to its Mexican subsidiary (see Note 5
to the Audited Consolidated Financial Statements).
 
    The Company continues to believe in this subsidiary's ability to become a
significant contributor to operating profits in future periods.
 
FOREIGN CURRENCY TRANSLATION
 
    As discussed in Note 1 to the Audited Consolidated Financial Statements,
operations of the Company's Mexican subsidiary have been measured in local
currency and translated into U.S. dollars for the inclusion in the Company's
consolidated financial statements. The Company has advanced funds to purchase
equipment and support operations during its development stage. These advances
are not expected to be repaid in the foreseeable future. The exchange gains and
losses arising from fluctuations in the rate of exchange between U.S. Dollars
and New Pesos have therefore been recorded as a separate component of
shareholders' equity. The business transactions in Mexico including sales,
payment of wages and salaries, auto costs, etc., are all conducted in New Pesos.
 
    Effective January 1, 1997, the functional currency of the Mexican subsidiary
has changed for accounting purposes from the Mexican New Peso to the U.S. Dollar
due to the Mexican economy meeting the definition of a highly inflationary
economy under generally accepted accounting principles. As a result of this
change, future transaction and translation gains and losses will be included in
the Company's statements of operations resulting from changes in the exchange
rate applied to inventories, fixed assets and dollar denominated inter-company
debt. The Mexican subsidiary's exchange gains and losses computed on the
subsidiary's dollar denominated debt owed to the Company have been included as a
separate component of shareholders' equity through December 31, 1996.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Shareholders and Board of Directors of Harmony Brook, Inc.:
 
    We have audited the accompanying consolidated balance sheets of Harmony
Brook, Inc. and Subsidiary as of December 31, 1996 and 1995, and the related
consolidated statements of operations, shareholders' equity, and cash flows for
the years then ended. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Harmony Brook,
Inc. and Subsidiary as of December 31, 1996 and 1995, and the consolidated
results of their operations and their cash flows for the years then ended in
conformity with generally accepted accounting principles.
 
    While the Company has continued operations for a period in excess of one
year from the date of the most recent balance sheet included herein, subsequent
to February 7, 1997, management of the Company has determined that the Company
is in immediate need of additional capital. As described in Note 2 to the
consolidated financial statements, the Company's ability to continue as a going
concern through the end of 1998 is dependent upon consummation of the merger
with Culligan or management's ability to successfully raise additional capital.
The consolidated financial statements do not include any adjustments relating to
the recoverability and classification of recorded asset amounts or the amounts
or classification of liabilities that might be necessary should the Company be
unable to continue as a going concern.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    BUSINESS DESCRIPTION
 
    Harmony Brook, Inc. (the "Company") develops, manufactures, markets,
distributes and operates equipment which processes ordinary tap water into
high-quality drinking water at the point of use. The Company's principal product
line consists of the Harmony Brook-Registered Trademark- Premium Drinking Water
system, a self-serve dispensing system for use in supermarkets and other retail
locations. In January 1994, the Company established a wholly owned subsidiary in
Mexico where the Company has installed its equipment in supermarket and retail
store locations.
 
    The Company commenced operations in late 1989. Under the Company's revenue
sharing leases, systems are leased to supermarkets and other retailers who pay a
fee based on the amount of water used or dispensed. In addition to such leasing
arrangements, the Company engages in the sale of its manufactured equipment to
licensed dealers. The Company maintains field offices in various parts of the
United States and Mexico, and also distributes its products through a network of
independent dealers. The Company sells a line of one, two, three and five gallon
containers to be used with its systems and sells containers to third parties on
a wholesale basis.
 
    PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements for the years ended December 31, 1996
and 1995, include the accounts of the Company and its wholly-owned Mexican
subsidiary. All significant intercompany accounts and transactions have been
eliminated in consolidation.
 
    FOREIGN CURRENCY TRANSLATION
 
    Financial position and results of operations of the Company's Mexican
subsidiary are measured using local currency as the functional currency. Assets
and liabilities of the subsidiary are translated at the exchange rate in effect
at the end of the period.
 
    Statements of operations accounts are translated at the average rates of
exchange prevailing during the period. Translation adjustments arising from the
use of differing exchange rates are included in the cumulative foreign currency
translation adjustments account in shareholders' equity. Sales by the Company's
Mexican subsidiary are negotiated, invoiced and paid in New Pesos.
 
    Effective January 1, 1997, the Mexican subsidiary will be accounted for as a
hyperinflationary economy and use the U.S. dollar as the functional currency.
Therefore, certain assets and liabilities will be translated at historical
exchange rates and all translation gains and losses included in the Company's
Consolidated Statement of Operations.
 
    USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. The most
significant areas which require the use of management's estimates relate to the
determination of allowances for uncollectible accounts receivable and obsolete
inventories, estimated

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
useful lives of dispensing equipment for computing depreciation and
amortization, recoverability of long-lived assets, and the valuation allowance
for deferred tax assets.
 
    CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents consist of checking accounts and a money market
fund, substantially all of which are held in one depository institution. The
Company considers all highly liquid investments purchased with an original
maturity of three months or less to be cash equivalents.
 
    INVENTORIES
 
    Inventories consist of bottles and also raw materials and spare parts
expected to be used in the production of equipment for sale to dealers and are
stated at the lower of cost or market. Cost is determined using standard costs,
which approximate the first-in, first-out method.
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment, which includes raw materials and spare parts
expected to be used in the production of dispensing equipment to be placed in
customer locations under revenue sharing leases and dispensing equipment
awaiting installation, are stated at cost. The cost of dispensing equipment
includes actual raw material costs plus an allocation of labor and overhead
costs. Except for dispensing equipment, depreciation and amortization is
computed using the straight-line method over estimated useful asset lives of
three to seven years. Depreciation and amortization of dispensing equipment
begins once the equipment is installed and is computed using the greater of an
amount calculated using the units-of-production (based on gallons of water
produced) method or 25% of that which would have been recorded using the
straight-line method based on an estimated useful life of 12 years.
 
    When property and equipment is retired from service or otherwise disposed
of, the cost and related accumulated depreciation and amortization are removed
from the asset accounts with the resulting gain or loss included in operations.
Expenditures for maintenance and repairs which do not improve or extend the life
of the respective assets are expensed as incurred. The Company reviews property
and equipment on a quarterly basis in order to assess recoverability based on
projected income and related cash flows on an undiscounted basis.
 
    OTHER ASSETS
 
    Other assets consist primarily of the excess of acquisition cost over the
fair value of the net assets acquired (goodwill), which is amortized on a
straight-line basis over 10 years. The Company reviews goodwill on a quarterly
basis in order to assess recoverability based on projected income and related
cash flows on an undiscounted basis.
 
    PREFERRED STOCK
 
    The Company's Articles of Incorporation, as amended on March 1, 1993,
authorizes the issuance of 5,000,000 shares of preferred stock. The rights,
preferences and privileges of the authorized shares may be established by the
Board of Directors without further action by the holders of the Company's common
stock. As of December 31, 1996, none has been issued.

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    REVENUE RECOGNITION
 
    Contracted revenue sharing, which represents revenues from dispensing
equipment under operating lease agreements, is recognized as the water is sold
to the customer. Revenues from bottle sales and equipment sales are recognized
upon shipment or delivery of services. Accounts receivable from customers are
uncollateralized.
 
    INCOME TAXES
 
    The Company utilizes the asset and liability method of accounting for income
taxes whereby deferred taxes are determined based on the difference between the
financial reporting and tax bases of assets and liabilities using enacted tax
rates applicable to the periods in which the differences are expected to affect
taxable income. Valuation allowances are established when necessary to reduce
deferred tax assets to the amount expected to be realized. Income tax expense is
the tax payable for the period and the change during the period in deferred tax
assets and liabilities.
 
    LOSS PER SHARE
 
    Loss per share is computed using the weighted average number of shares of
common stock outstanding. Common stock equivalents are anti-dilutive.
 
2.  PROPOSED MERGER AND ADDITIONAL CAPITAL REQUIREMENTS
 
    On January 12, 1998, the Company entered into an Agreement and Plan of
Merger and Reorganization (the Merger Agreement) whereby the Company would be
merged into Culligan Acquisition Corp., a wholly-owned subsidiary of Culligan
International Company (Culligan). Under the terms of the Merger Agreement, which
is subject to approval by the Company's shareholders, the Company would become a
wholly-owned subsidiary of Culligan, and each outstanding share of the Company's
common stock would be converted into the right to receive $0.545 in cash.
 
    In the event the Company's shareholders do not approve the Merger Agreement,
the Company will need to obtain additional capital immediately to continue under
the Company's current operating plan. In January 1998, the Company obtained
bridge financing of $50,000 from the Chairman of its Board of Directors. The
Company obtained agreements from its two senior lenders to suspend principal
payments due in November 1997 through February 1998. The Company expects, upon
finalization of its fourth quarter 1997 financial results, that it will have
violated certain financial covenants contained in the loan agreement with its
principal bank lender. Management of the Company is currently uncertain about
its ability to obtain the necessary additional capital should the Merger
Agreement be terminated.
 
    The actions described in the previous paragraph have allowed the Company to
continue operations into January 1998 (more than a year from the date of the
most recent balance sheet included herein). However, the Company's ability to
continue as a going concern through the end of 1998 is dependent upon
consummation of the merger with Culligan or management's ability to successfully
raise additional capital. The consolidated financial statements do not include
any adjustments relating to the recoverability and classification of recorded
asset amounts or the amounts or classification of liabilities that might be
necessary should the Company be unable to continue as a going concern.

3.  ACQUISITION
 
    On December 14, 1995, the Company acquired certain assets of Certified Pure
Water of Illinois, Inc. (Certified Pure Water), an owner and operator of
self-serve point of use water treatment equipment in northern Illinois with 49
existing customer locations, in exchange for 333,333 shares of common stock
(valued at $250,000) and cash of $175,000. The acquisition has been accounted
for as a purchase and, accordingly, the results of the operation of these units
since December 14, 1995 have been included in the Company's financial
statements.
 
    Unaudited pro forma data, as though the acquisition of Certified Pure
Water's assets had been effective at the beginning of 1995 are as follows:

    Prior to the amendment and restatement described in the following
paragraphs, the bank agreement contained restrictive financial covenants which
included, among others, requirements that the Company maintain a current ratio
of at least 0.75 to 1, maintain an annual minimum coverage ratio of 1.1 to 1,
achieve annual net income of at least $50,000 in 1996 and $300,000 in each
successive year thereafter, maintain minimum levels of capital base, and
maintain a minimum cash balance of $150,000 on deposit with the bank at all
times, and which prohibited the Company from paying any dividends. At December
31, 1996, the Company was in violation of the net income, current ratio,
cumulative net loss, minimum capital base and minimum coverage ratio covenants.
The Company has obtained a written waiver from the bank waiving its right to
accelerate repayment as part of an amended and restated loan agreement dated
February 18, 1997 (see following two paragraphs).
 
    On February 18, 1997, the Company and the bank amended an restated its term
loan agreement. The agreement combined both outstanding term loans into one term
loan facility to be repaid in equal monthly principal installments plus accrued
interest at the bank's reference rate plus 3.75 percent, with a final principal
payment plus accrued interest due in February 2000. Borrowings under the amended
and restated term loans are collateralized by substantially all of the Company's
assets, subordinate to a leasing company's collateral interest in certain leased
dispensing equipment. In addition, the bank agreement contains restrictive
financial covenants which include, among others, that the Company maintain a
current ratio of at least 0.75 to 1, maintain an annual minimum coverage ratio
of 1.05 to 1, maintain a minimum cash balance of $150,000 on deposit with the
bank at all times, and which prohibits the Company from paying any dividends.

5.  FINANCING ARRANGEMENTS (CONTINUED)
    The amended and restated term loan agreement has a provision that if the
Company did not obtain commitments for at least $1,000,000 of new subordinated
debt financing by March 1, 1997, an event of default would occur. The agreement
also requires that 30 percent of the gross proceeds of the subordinated debt are
to be used to pay down the principal balance with its bank lender (see following
paragraph).
 
    In February 1997, the Company obtained commitments for the purchase of a
series of subordinated notes payable from shareholders and accredited investors
sufficient to meet the provisions of the amended and restated term loan
agreement. The notes bear interest at 14 percent payable monthly and are due in
March 2000. In addition, warrants were offered in conjunction with the notes at
the rate of one warrant for each $5.00 in notes payable. The notes are
collateralized by a second lien on all of the Company's assets, subordinate to
the bank and leasing company's interests.
 
    On July 28, 1995, the Company entered into a $200,000 bridge loan agreement
bearing interest at 13% per annum with its Chairman. The Company borrowed
$100,000 pursuant to this agreement on October 12, 1995. The entire principal
balance was repaid on October 25, 1995 in conjunction with the sales of its
common stock.
 
    On January 5, 1996, the Company and a leasing company amended their loan
agreement. The amended loan agreement extended the payment terms and provides
for escalating monthly principal payments plus accrued interest through June
1999. The leasing company received a new warrant for 300,000 shares of common
stock which replaced a warrant for 200,000 shares of common stock that was
canceled as part of this amended loan agreement (see Note 8).
 
    The Company believes that the amount recorded as a long-term debt
approximates its fair value at December 31, 1996.
 
    Principal maturities of long-term debt at December 31, 1996, which reflect
the maturities in the February 1997 financing transactions, are as follows:

6.  LEASES
 
    AS LESSOR
 
    The Company leases dispensing equipment with a carrying value of $7,099,000
net of accumulated depreciation of $2,651,000 at December 31, 1996, to customers
under cancelable operating leases with one to five year terms. Terms of the
lease agreement provide both the Company and the lessee with the option to
remove the equipment if, after six months, water sales are less than minimum
levels. Monthly lease payments are based on actual usage and are subject to
minimum payment amounts. The leases also require the Company to service and
maintain the equipment.

6.  LEASES (CONTINUED)
    AS LESSEE
 
    Certain office and production facilities, vehicles and office equipment are
leased under noncancelable operating lease expiring at various dates through
2000. The minimum monthly rentals under these agreements vary from
month-to-month because certain leases require the Company to pay a pro rata
share of the lessor's operating costs. Also, certain leases are renewable at the
Company's option. Future minimum lease payments on these leases are $192,000,
$146,000, $58,000, $23,000 and $1,000 in 1997, 1998, 1999, 2000 and 2001,
respectively.
 
    During 1996, the Company entered into various sale/leaseback agreements with
certain shareholders and Board members for dispensing equipment. These
agreements were approved by the Company's principal bank lender under the terms
that the equipment be installed and operated with one named chain customer and
that the installations consist of newly manufactured equipment. Under the terms
of the agreements, 27 systems were sold for $171,000 ($6,345 per system) and
were leased back by the Company pursuant to five-year operating leases for
placement and operation in one supermarket chain. The leases require a monthly
payment of $4,000 ($140 per system) and requires the Company to service and
maintain the equipment. The monthly payment per system can increase based on
increases in the prime interest rate. In addition, the Company has the option to
purchase the equipment at the end of the lease term for its fair market value.
Deferred income of $82,000 is being amortized as a reduction of cost of revenues
on a straight-line basis over the lease terms. At December 31, 1996, the
unamortized portion of this deferred income included on the Company's balance
sheet was $75,000.
 
    During 1991 and 1990, the Company entered into various sale-leaseback
agreements with certain shareholders and Board members for dispensing equipment.
All of these leases expired during 1996 and the Company exercised its option to
purchase the equipment from the lessors at its fair market value for a total
purchase price of $148,000.
 
    Rent expense was approximately $267,000 in 1996 and $514,000 in 1995, of
which approximately $29,000 in 1996 and $250,000 in 1995 related to the
sale-leaseback agreements with certain shareholders and Board members.
 
    The Company also leased certain property and equipment pursuant to terms of
a master sale-leaseback agreement with a leasing company. A board member and
shareholder in the leasing company is also Chairman of the Board and a
significant shareholder of the Company. The capital lease agreements expired in
December 1995 and March 1996.

periods.
 
8.  STOCK OPTIONS AND WARRANTS
 
    On April 25, 1996, the Company adopted the 1996 Stock Option Plan (1996
Plan) which provides for a maximum of 350,000 shares of common stock available
for grant. On April 20, 1995, the Company adopted the 1995 Stock Option Plan
(1995 Plan) which provides for a maximum of 150,000 shares of common stock
available for grant. On March 1, 1993, the Company adopted the 1993 Stock Option
Plan (1993 Plan) which provides for a maximum of 150,000 shares of common stock
available for grant. The 1996 Plan, 1995 Plan and the 1993 Plan (collectively
"the Option Plans") are administered by the Compensation Committee of the Board
of Directors (the "Committee"). The Option Plans provide that options granted
thereunder may be either incentive stock options (ISOs) as defined by the
Internal Revenue Code, or nonqualified stock options. Options may be granted to
key employees and officers of the Company. The Committee determines who will
receive options under the Option Plans and sets the terms. Options may have a
maximum term of no more than ten years and have vesting periods of three years.
The exercise price of all ISOs granted under the Option Plans must be at least
equal to the fair market value of the Company's common stock on the date of
grant. The exercise price may be paid in cash, options, or shares of previously
owned common stock. If an option expires, terminates or is canceled, the shares
not purchased thereunder may become available for additional option awards under
the Option Plans. The 1996 Plan, 1995 Plan and the 1993 Plan expire on April 24,
2006, April 19, 2005 and February 28, 2003, respectively.

8.  STOCK OPTIONS AND WARRANTS (CONTINUED)
 
    On March 1, 1993, the Company also adopted the Outside Directors'
Nonqualified Stock Option Plan (the Directors Plan) which is administered by the
Board of Directors (the "Board"). Options are to be granted to only those
directors of the Company who are not members of management. The maximum number
of shares of common stock available for grant under the Directors Plan is
75,000. The Directors Plan provides for automatic annual grants to each outside
director of options to purchase 2,000 shares with an exercise price equal to the
fair market value on the date of grant. Options may have a term of no more than
ten years and vest at the rate of 20% of the original grant per year. The
exercise price may be paid in cash, options or shares of previously owned common
stock. The Directors Plan expires on February 28, 2003.
 
    In addition, the Board granted to certain directors nonqualified stock
options to purchase 60,000 shares of the Company's common stock at $3.00 per
share on March 1, 1993. In 1994, 10,000 of these stock options were forfeited.
These options were not granted under any of the plans discussed above and vest
at the rate of 20% per year over five years.
 
    Option activity is summarized below. Aggregate activity related to the 1996
Plan, 1995 Plan, 1993 Plan and Directors Plan is presented separately from other

    In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, a new standard of accounting and
reporting for stock-based compensation plans. The Company adopted this new
standard in 1996. The Company has continued to measure compensation cost

for its stock option plans using the intrinsic value-based method of accounting
it has historically used and, therefore, the new standard has no effect on the
Company's operating results.
 
    Had the Company used the fair value-based method of accounting for its stock
option plans beginning in 1995 and charged compensation cost against operations
over the vesting period, based on the fair value of options at the date of
grant, net loss and net loss per share for 1996 and 1995 would have been the
following pro forma amounts:

    The pro forma information above only includes stock options granted in 1995
and 1996. Compensation expense under the fair value-based method of accounting
will increase over the next few years as additional stock option grants are
considered.
 
    The Company used the Black-Scholes option pricing model to value its options
using the following assumptions: risk free interest rates ranging from 5.7% to
7.8%, expected life of the options of five years, expected volatility of 54.5%,
and no expected dividends. The weighted average fair value of options on the
date of grant was $0.79 and $0.48 for options granted in 1995 and 1996,
respectively.
 
    On December 6, 1996, the Company's Board of Directors authorized the
cancellation of outstanding incentive stock options and reissuance of new
options to current employees excluding those employees who are also Directors.
This action by the Board is subject to acceptance by each employee. The reissued
options will have an exercise price of $0.63 per share. If all employees elect
to cancel their outstanding options in return for new options, options covering
249,733 shares at a weighted average exercise price of $0.63 per share would
replace options covering 249,733 shares at a weighted average exercise price of
$0.99 per share. All reissued options will be ten-year options with a vesting
period of three years beginning on December 6, 1996.
 
    The Company has issued stock warrants to shareholders and others in
conjunction with various financing activities. Net proceeds from the issuance of
the note payable and related warrants in 1994 were allocated based on the
relative fair values on the issue date. All warrants are fully vested with the
holder.
 
    Warrant activity is summarized as follows:

                            CONVERSION OF SECURITIES
 
    SECTION 2.1. CONVERSION OF CAPITAL STOCK.  As of the Effective Time, by
virtue of the Merger and without any action on the part of the holder of any
shares of Common Stock, no par value per share, of the Company (the "Company
Common Stock") or the holder of any capital stock of Merger Sub:
 
    (a) Each issued and outstanding share of Common Stock, par value $1.00 per
       share, of Merger Sub (the "Merger Sub Common Stock") be converted into
       one share of common stock of the Surviving Corporation.
 
    (b) All shares of Company Common Stock that are owned by the Company as
       treasury stock and any shares of Company Common Stock owned by Parent or
       any wholly owned Subsidiary of Parent shall be cancelled and retired and
       shall cease to exist and no consideration shall be delivered in exchange
       therefor.
 
    (c) Subject to SECTION 2.2(b), each issued and outstanding share of Company
       Common Stock (other than shares to be cancelled in accordance with
       SECTION 2.1(b)) shall be converted into the right to receive $.545 in
       cash (the "Consideration"). All such shares of Company Common Stock, when
       so converted, shall no longer be outstanding and shall automatically be
       cancelled and retired and shall cease to exist, and each holder of a
       certificate representing any such shares shall cease to have any rights
       with respect thereto, except the right to receive cash to be paid in
       consideration therefor upon the surrender of such certificate in
       accordance with SECTION 2.2, without interest.
 
    (d) If after the date hereof and prior to the Effective Time the
       out-standing shares of Company Common Stock shall have been changed into
       a different number of shares or a different class, by reason of any stock
       dividend, subdivision, reclassification, recapitalization, split,
       combination or exchange of shares, the Consideration shall be

    SECTION 2.2. EXCHANGE OF CERTIFICATES.
 
    (a) Promptly following the Closing Date, Parent shall deposit with a bank or
       trust company designated by Parent and reasonably acceptable to the
       Company (the "Exchange Agent"), for the benefit of the holders of shares
       of Company Common Stock, for exchange in accordance with this ARTICLE II,
       through the Exchange Agent, the aggregate Consideration to be paid to
       holders of the Company Common Stock in the Merger (the "Exchange Fund").
 
    (b) As soon as practicable after the Effective Time, the Surviving
       Corporation shall cause the Exchange Agent to mail to each holder of
       record of a certificate or certificates which immediately prior to the
       Effective Time represented outstanding shares of Company Common Stock
       (the "Certificates") whose shares were converted pursuant to SECTION 2.1
       into the right to receive the Consideration (i) a letter of transmittal
       (which shall be in such form and have such provisions as Parent and the
       Company may reasonably specify) and (ii) instructions for use in
       effecting the surrender of the Certificates in exchange for the
       Consideration. Upon surrender of a Certificate for cancellation to the
       Exchange Agent or to such other agent or agents as may be appointed by
       Parent, together with such letter of transmittal, duly executed, the
       holder of such Certificate shall be entitled to receive in exchange
       therefor the Consideration to which such holder is entitled pursuant to
       SECTION 2.1(c) hereof, after giving effect to any required tax
       withholdings, and the Certificate so surrendered shall forthwith be
       cancelled. In the event of a transfer of ownership of Company Common
       Stock which is not registered in the transfer records of the Company, the
       Consideration payable to the transferee thereof in the Merger may be
       issued to a transferee if the Certificate representing such Company
       Common Stock is presented to the Exchange Agent, accompanied by all
       documents required to evidence and effect such transfer and by evidence
       that any applicable stock transfer taxes have been paid. Until
       surrendered as contemplated by this SECTION 2.2, each Certificate shall
       be deemed at any time after the Effective Time to represent only the
       right to receive upon such surrender the Consideration payable in the
       Merger.
 
    (c) (i) Notwithstanding any provision of this Agreement to the Contrary, the
            holder (a "Dissenting Shareholder") of any shares of Company Common
            Stock who has demanded and perfected such holder's demand for
            appraisal of said shares (the "Dissenting Shares") in accordance
            with Sections 302A.471 and 302A.473 of the MBCA and as of the
            Effective Time has neither effectively withdrawn nor lost his or her
            right to such appraisal shall not have a right to receive the
            Consideration for such Dissenting Shares pursuant to Section 2.1(c)
            and shall only be entitled to such rights as are granted by the
            MBCA. The Surviving Corporation shall make any and all payments due
            to holders of Dissenting Shares.
 
        (ii) Notwithstanding the provisions of 2.2(c)(i), if any Dissenting
             Shareholder demanding appraisal of such Dissenting Shareholder's
             Dissenting Shares under the MBCA shall effectively withdraw or lose
             (through failure to perfect or otherwise) his or her right to
             appraisal, then as of the Effective Time or the occurrence of such
             event, whichever occurs later, such Dissenting Shares shall
             automatically be converted into and represent only the right to
             receive the Consideration as provided in SECTION 2.1(c) upon
             surrender of the certificate or certificates representing such
             Dissenting Shares.
 
       (iii) The Company shall give Parent and Merger Sub prompt notice of any
             demand by a Dissenting Shareholder for payment, or notices of
             intent to demand payment received by the Company under Sections
             302A.471 and 302A.473 of the MBCA, and Parent and Merger Sub shall
             have the right to participate in all negotiations and proceedings
             with respect to such demands. The Company shall not, except with
             the prior written consent of Parent (which consent shall not be
             unreasonably withheld or delayed) or as otherwise required by law,
             make any payment with respect to, or settle, or offer to settle,
             any such demands.
 
                                      A-4
<PAGE>
    (d) All of the Consideration paid upon shares of Company Common Stock in
       accordance with the terms hereof shall be deemed to have been paid in
       full satisfaction of all rights pertaining to such shares of Company
       Common Stock.
 
    (e) Any portion of the Exchange Fund which remains undistributed to the
       stockholders of the Company for six months after the Effective Time shall
       be delivered to the Surviving Corporation, upon demand, and any
       stockholders of the Company who have not theretofore complied with this
       ARTICLE II shall, subject to any applicable abandoned property, escheat
       or similar law, thereafter look only to the Surviving Corporation for the
       Consideration payable in the Merger.
 
    (f) None of Parent, Merger Sub nor the Company shall be liable to any holder
       of shares of Company Common Stock for such cash payable in the Merger
       delivered to a public official pursuant to any applicable abandoned
       property, escheat or similar law.

<PAGE>
    (b) The Company and the Mexican Subsidiary have not, as of and since the
       date upon which they acquired any of the Proprietary Rights, (i)

    (c) To the best of the Company's knowledge, the conduct of the business of
       the Company and the Mexican Subsidiary as currently conducted does not
       conflict or infringe in any way with any proprietary right of any third
       party that, individually or in the aggregate, is reasonably likely to
       have a material adverse effect on the Company or the Mexican Subsidiary,
       and there is no claim, suit, action or proceeding pending or to the
       knowledge of the Company threatened against the Company or the Mexican

which
 
                                      A-9
<PAGE>
could materially and adversely affect the Company, its assets, financial
condition, results of operations or prospects, the Business, or the transactions
contemplated hereby. The Company is not a party to or subject to the provisions
of any judgment, order, writ, injunction, decree or award of any court,

Company or the Mexican Subsidiary.
 
    SECTION 3.18. EMPLOYMENT AGREEMENTS AND EMPLOYEE BENEFIT PLANS.
 
    (a) Except as set forth in SCHEDULE 3.12 or SCHEDULE 3.18, neither the
       Company nor the Mexican Subsidiary has, and has not had at any time, any
       bonus, deferred compensation, pension, retirement, profit-sharing,
       thrift, savings, employee stock ownership, stock bonus, stock purchase,
       restricted stock or stock option plans, employment or severance
       contracts, other material employee benefit plans and any applicable
       "change of control" or similar provisions in any plan, contract or
       arrangement which cover employees or former employees ("Company
       Employees") of the Company or any entity (an "ERISA Affiliate") which is
       considered one employer with the Company under Section 4001(b)(1) of the
       Employee Retirement Income Security Act of 1974, as amended ("ERISA"), or
       Section 414(b) or (c) of the Internal Revenue Code of 1986, as amended
       (the "Code") or any other benefit plans, contracts or arrangements
       (regardless of whether they are funded or unfunded or foreign or
       domestic) covering Company Employees, including, but not limited to,
       "employee benefit plans" within the meaning of Section 3(3) of the ERISA
       (collectively, the "Compensation and Benefit Plans"). The Company has
       made available to Parent true and complete copies of all the Compensation
       and Benefit Plans, including any trust instruments and/or insurance
       contracts, if any, forming a part of any such plans, and all amendments
       thereto; where applicable, current summary plan descriptions; where
       applicable, the most current determination letter received from the
       Internal Revenue Service (the "Service") and most recent
 
                                      A-10
<PAGE>
       determination letter application, and where applicable, annual reports,
       financial statements and actuarial reports for the last three plan years
       ending before December 31, 1997, which fairly and accurately reflect the
       financial condition of the plans.
 
    (b) All of the Compensation and Benefit Plans, to the extent subject to
       ERISA, are in material compliance with ERISA. Each Compensation and
       Benefit Plan which is an "employee pension benefit plan" within the
       meaning of Section 3(2) of ERISA ("Pension Plan") and which is intended
       to be qualified under Section 401(a) of the Code, has received a
       favorable determination letter from the Service, and the Company is not
       aware of any circumstances likely to result in revocation of any such
       favorable determination letter. Neither the Company nor any ERISA
       Affiliate has engaged in a transaction with respect to any Compensation
       and Benefit Plan that, assuming the taxable period of such transaction
       expired as of the date hereof, could subject the Company or any ERISA
       Affiliate to a tax or penalty imposed by either Section 4975 of the Code
       or Section 502(i) of ERISA in an amount which would have a material
       adverse effect on the Company. Neither the Company nor any ERISA
       Affiliate has contributed or been required to contribute to any
       Multi-employer Pension Plan subject to Subtitle E of Title IV of ERISA.
 
    (c) No liability under Subtitles C or D of Title IV of ERISA has been or is
       expected to be incurred by the Company or any ERISA Affiliate with
       respect to any ongoing, frozen or terminated Compensation and Benefit
       Plan, currently or formerly maintained by any of them.
 
    (d) All contributions required to be made or accrued as of December 31, 1996
       under the terms of any Compensation and Benefit Plan for which the
       Company or the Mexican Subsidiary may have liability have been timely
       made or have been reflected on the Balance Sheet. No Pension Plan has
       incurred an "accumulated funding deficiency" (whether or not waived)
       within the meaning of Section 412 of the Code or Section 302 of ERISA.
       Neither the Company nor any ERISA Affiliate has provided, or is required
       to provide, security to any Pension Plan pursuant to Section 401(a)(29)
       of the Code.
 
    (e) Except as set forth in SCHEDULE 3.12 or SCHEDULE 3.18, the Company does
       not have any obligations for retiree health and life benefits under any
       Compensation and Benefit Plans.
 
    (f) All Compensation and Benefit Plans covering foreign Company Employees
       comply in all material respects with applicable local law. The Company
       and the Mexican Subsidiary have no unfunded liabilities in an amount
       which would have a material adverse effect on the Company with respect to
       any Pension Plan which covers foreign Company Employees.
 
    (g) Except as expressly provided in this Agreement or as set forth on
       SCHEDULE 3.12 or SCHEDULE 3.18, the consummation of the transactions
       contemplated by this Agreement will not (i) entitle any current or former
       employee or officer of the Company or any ERISA Affiliate to severance
       pay, unemployment compensation or any other payment, except as expressly
       provided in this Agreement or (ii) accelerate the time of payment or
       vesting, or increase the amount of compensation due any such employee or
       officer.
 
    (h) The Company has no unfunded liabilities with respect to any Pension Plan
       which covers former Employees in an amount which would have a material
       adverse effect on the Company or the Mexican Subsidiary.
 
    (i) Except with respect to employees of the Mexican Subsidiary, immediately
       after the Effective Time, the Surviving Corporation could terminate each
       Compensation and Benefit Plan in accordance with its terms and applicable
       law without incurring any material liability.
 
    (j) Except as expressly provided in this Agreement or as set forth on
       SCHEDULE 3.12 or SCHEDULE 3.18, with respect to the Company, the Mexican
       Subsidiary and the Business, the transactions contemplated by this
       Agreement will not cause any additional payments to be due under any
       Compensation and Benefit Plan, nor accelerate the payment or vesting of
       any amounts due under any
 
                                      A-11
<PAGE>
       Compensation and Benefit Plan, nor result in any excess parachute payment
       within the meaning of Code Section 280G except for payments which are
       paid prior to the Effective Time, accrued on the Balance Sheet or for
       which funds have been reserved.
 
    (k) There are no pending, or to the best of the Company's knowledge,
       threatened or anticipated claims by or on behalf of any Compensation and
       Benefit Plan, by any employee or beneficiary covered under any such
       Compensation and Benefit Plan, or otherwise involving any such
       Compensation and Benefit Plan (other than routine claims for benefits).
 
    (l) As of the date hereof, the Mexican Subsidiary is in compliance with all
       material provisions of Mexican law with respect to imposition with
       respect to its employees, except where the failure to so comply will not
       have a material adverse effect on the Business or the Company's or the
       Mexican Subsidiary's financial condition, results of operations or
       prospects.
 
    SECTION 3.19. EMPLOYEES.  SCHEDULE 3.19 sets forth a complete and correct
list, as of the date hereof, of the names and current annual salary rates of any
officer or employee of the Company or the Mexican Subsidiary whose current
regular annual compensation is $5,000 or more, together with a list of all
bonuses paid to any such persons for the Company's last two fiscal years, and,
to the extent existing on the date hereof, all arrangements with respect to any

product liability, workmen's compensation, vehicular and other insurance held by
or on behalf of the Company or the Mexican Subsidiary are set forth on SCHEDULE
3.20. Each such policy or binder is valid and enforceable in accordance with its
terms, and is in full force and effect. No notice has been received from any
insurer with respect to the cancellation of, or intent to cancel, or the
non-renewal of, any of such policies. Except as set forth on SCHEDULE 3.20, to
the Company's knowledge, no event has occurred which could result in a
cancellation of any of the insurance policies set forth on such Schedule or a
refusal by the insurer to pay under such policies, nor has the Company or the
Mexican Subsidiary failed to make any claim under any such policies in a due and
timely fashion.
 
    SECTION 3.21. BANK ACCOUNTS AND POWERS OF ATTORNEY.  SCHEDULE 3.21 sets
forth: (a) the name of each bank in which the Company or the Mexican Subsidiary
has an account or safe deposit box, the identifying numbers or symbols therefor
and the name of each person authorized to draw thereon or to have access
thereto; and (b) the name of each person, if any, holding powers of attorney
from the Company or the Mexican Subsidiary, true copies of which have previously
been delivered to Parent and Merger Sub.
 
    SECTION 3.22. TRANSACTIONS WITH AFFILIATES.  As of the date hereof, except
(i) as was disclosed in the Company's proxy statement for its 1997 annual
meeting of stockholders (the "1997 Proxy Statement"), or (ii) as disclosed in
SCHEDULE 3.22, (i) there are no outstanding notes payable to or accounts
receivable from, or advances by the Company or the Mexican Subsidiary to, and
neither the Company nor the Mexican Subsidiary is otherwise a creditor of, any
stockholder, officer, director, employee, or affiliate of the Company, other
than any such transactions which do not exceed $1,000 individually or $10,000 in
the aggregate, and (ii) neither the Company nor the Mexican Subsidiary is a
party to any contract with any stockholder, officer, director, or employee of
the Company or the Mexican Subsidiary.

heretofore made available to Parent true and complete copies of, all forms,
reports and documents required to be filed since January 1, 1995 by it under the
Securities Act of 1933 (the "Securities Act") or the Securities Exchange Act of
1934 (the "Exchange Act") (as such documents have been amended since the time of
their filing, collectively, the "Company SEC Documents"). The Company SEC
Documents, including, without limitation, any financial statements or schedules
included therein, (a) did not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading and (b) complied in all material respects
 
                                      A-12
<PAGE>
with the applicable requirements of the Securities Act or the Exchange Act, as
the case may be. The consolidated financial statements of the Company included
in the Company SEC Documents (including the notes and schedules thereto, the
"Company Financial Statements") comply as to form in all material respects with
applicable accounting requirements and with the published rules and regulations
of the SEC with respect thereto.
 
    SECTION 3.24. INFORMATION IN DISCLOSURE DOCUMENTS AND REGISTRATION
STATEMENT.  None of the information supplied or to be supplied by the Company or
its representatives for inclusion or incorporation by reference in the Proxy
Statement relating to the meeting of the Company's stockholders to be held in
connection with the Merger (the "Proxy Statement") will, at the date mailed to
the Company's stockholders and at the time of the meeting of stockholders to be
held in connection with the Merger, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances

or the Mexican Subsidiary, contains any untrue statement of a material fact or
omits to state a material fact required to make the statements herein or therein

                           INDEMNIFICATION AGREEMENT
 
    This INDEMNIFICATION AGREEMENT made and entered into as of January 12, 1998
by and between Culligan International Company, a Delaware corporation
("Parent"), and Donald R. Brattain ("Indemnitor"). Certain terms used herein,
each of which is capitalized, that are defined in the Merger Agreement, as
hereinafter defined, are used herein with the meanings therein provided.
 
                              W I T N E S S E T H:
 
    WHEREAS, Indemnitor owned a substantial amount of the outstanding capital
stock of Harmony Brook, Inc., a Minnesota corporation (the "Company") and has
been active in the management of the Company;
 
    WHEREAS, the Board of Directors of the Company have determined that the
merger (the "Merger") of the Company with and into a newly-formed wholly owned
indirect subsidiary of Parent ("Merger Sub") pursuant to an Agreement and Plan
of Merger (the "Merger Agreement") dated as of January 12, 1998 among Company,
Parent and Merger Sub would be in the best interest of the Company's
stockholders; and
 
    WHEREAS, but for the agreements of Indemnitor contained herein Parent and
Merger Sub would not be willing to effect the transactions contemplated by the
Merger Agreement;
 
    NOW, THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, Parent and Indemnitor hereby agree as follows:
 
    SECTION 1. GENERAL INDEMNIFICATION OBLIGATION OF THE INDEMNITOR.  From and
after the Closing, the Indemnitor will reimburse, indemnify and hold harmless
Parent and its shareholders, officers, directors, successors and assigns
("Indemnitee") against and in respect of:
 
    (a) any and all damages, losses, deficiencies, liabilities, costs and
       expenses incurred or suffered by Indemnitee that are a direct result of a
       material misrepresentation or material breach of warranty on the part of
       the Company under the Merger Agreement or any Related Document; provided,
       however, that Indemnitor shall owe no obligation or indemnification to
       Indemnitee in connection with any adjustments made to the book value of
       the Company's assets on or after the Effective Time which adjustments are
       the result of, arise out of or relate in any way to an allocation of
       negative goodwill created as a result of the Merger.
 
    (b) any and all actions, suits, claims, proceedings, investigations,
       demands, assessments, audits, fines, judgments, costs and other expenses
       (including, without limitation, reasonable legal fees and expenses)
       incident to any of the foregoing or to the enforcement of this SECTION 1.
 
    SECTION 2. METHOD OF ASSERTING CLAIMS, ETC.  In the event that any claim or
demand for which Indemnitor would be liable to Indemnitee hereunder is asserted
against or sought to be collected from Indemnitee by a third party, the
Indemnitee shall promptly notify Indemnitor in writing of such claim or demand,
specifying the nature of such claim or demand and the amount or the estimated
amount thereof to the extent then feasible (which estimate shall not be
conclusive of the final amount of such claim and demand) (the "Claim Notice").
The Indemnitor shall then have ten business days from the personal delivery or
mailing of the Claim Notice (the "Notice Period") to notify the Indemnitee: (i)
whether or not he disputes his liability to the Indemnitee hereunder with
respect to such claim or demand and (ii) notwithstanding any such dispute,
whether or not he desires, at his sole cost and expense, to defend the
Indemnitee against such claim or demand.
 
                                      A-25
<PAGE>
    (a) If the Indemnitor disputes his liability with respect to such claim or
       demand or the amount thereof (whether or not the Indemnitor desires to
       defend the Indemnitee against such claim or demand as provided in
       paragraphs (b) and (c) below), such claim or demand shall not be settled
       without the prior written consent of the Indemnitee.
 
    (b) In the event that the Indemnitor notifies the Indemnitee within the
       Notice Period that it desires to defend the Indemnitee against such claim
       or demand, then, except as hereinafter provided, the Indemnitor shall
       have the right to defend the Indemnitee by appropriate proceedings;
       PROVIDED, HOWEVER, the Indemnitor shall not, without the prior written
       consent of the Indemnitee (which consent shall not be unreasonably
       withheld), consent to the entry of any judgment against the Indemnitee or
       enter into any settlement or compromise which does not include, as an
       unconditional term thereof, the giving by the claimant or plaintiff to
       the Indemnitee of a release, in form and substance satisfactory to the
       Indemnitee in its reasonable judgment, from all liability in respect of
       such claim or litigation. If Indemnitee desires to participate in, but
       not control, any such defense or settlement, it may do so at its sole
       cost and expense; PROVIDED, HOWEVER, that, if the Indemnitee reasonably
       believes that there exists or could arise a conflict of interest that,
       under applicable principles of legal ethics, could prohibit a single
       legal counsel from representing both the Indemnitee and the Indemnitor,
       the Indemnitor will bear the reasonable fees and expenses of separate
       counsel.
 
    (c) If the Indemnitor elects not to defend the Indemnitee against such claim
       or demand, whether by not giving the Indemnitee timely notice as provided
       above or otherwise, then the amount of any such claim or demand, or if
       the same be defended by the Indemnitor or by the Indemnitee (but
       Indemnitee shall not have any obligation to defend any such claim or
       demand) then that portion thereof as to which such defense is
       unsuccessful, in each case shall be conclusively deemed to be a liability
       of the Indemnitor hereunder, unless the Indemnitor shall have disputed
       his liability to the Indemnitee hereunder, as provided in paragraph (a)
       above.
 
    (d) In the event Indemnitee should have a claim against the Indemnitor
       hereunder that does not involve a claim or demand being asserted against
       or sought to be collected from it by a third party, the Indemnitee shall
       promptly send a Claim Notice with respect to such claim to the
       Indemnitor. If the Indemnitor does not notify the Indemnitee within the
       Notice Period that it disputes such claim, the amount of such claim shall
       be conclusively deemed a liability of the Indemnitor hereunder.
 
    SECTION 3. PAYMENT.  Upon the determination of the liability under SECTION 2
hereof, the Indemnitor shall pay to the Indemnitee, within ten business days
after such determination, the amount of any claim for indemnification made
hereunder. In the event that the Indemnitee is not paid in full for any such
claim pursuant to the foregoing provisions promptly after the other party's
obligation to indemnify has been determined in accordance herewith, it shall
have the right, notwithstanding any other rights that it may have against any
other person, firm or corporation, to set off the unpaid amount of any such
claim against any amounts owed by it under the Merger Agreement, the Related
Documents or otherwise. Upon the payment in full of any claim, either by set-off
or otherwise, the Indemnitor shall be subrogated to the rights of the Indemnitee
against any person, firm or corporation with respect to the subject matter of
such claim.
 
    SECTION 4. LIMITATIONS ON INDEMNIFICATION.  Notwithstanding any other
provision in this Agreement to the contrary, (i) the Indemnitor shall not be
liable to indemnify Indemnitee until the aggregate of all claims for which
indemnity is made by Indemnitee hereunder shall exceed $150,000, (the "Basket")
in which case the Indemnitor shall be liable only for such amounts which exceed
the Basket up to the maximum amount provided in (x) below and (ii) the
Indemnitor shall not be liable to indemnify Indemnitee for (x) claims exceeding
in aggregate $1,000,000 and (y) claims for which the Indemnitor has not received
a Claim Notice on or prior to 5:00 Minneapolis time on the date which is one
year after the Effective Time.
 
                                      A-26
<PAGE>
    SECTION 5. OTHER RIGHTS AND REMEDIES NOT AFFECTED.  The indemnification
rights of the parties under this Agreement are independent of and in addition to
such rights and remedies as Indemnitee may have at law or in equity or otherwise
for any misrepresentation, breach of warranty or failure to fulfill any
agreement or covenant hereunder on the part of any party hereto, including
without limitation the right to seek specific performance, rescission or
restitution, none of which rights or remedies shall be adversely affected or
diminished hereby.
 
    SECTION 6. FAILURE TO ENFORCE AND WAIVER.  The failure to insist upon strict
compliance with any of the terms, covenants or conditions of this Agreement
shall not be deemed a waiver of such terms, covenants or conditions, and the
waiver or relinquishment of any right or power under this Agreement at any one
or more times shall not be deemed a waiver or relinquishment or such right or
power at any other time or times.
 
    SECTION 7. ASSIGNMENT.  The rights and obligations of Parent under this
Agreement (i) are assignable by Parent to any parent or subsidiary of Parent, to
any successor by merger to Parent and to any person which acquires all or
substantially all of the assets and business of Parent as a going concern and
(ii) shall inure to the benefit and shall be binding upon the successors and
assigns of Parent and Indemnitor.
 
    SECTION 8. NOTICES.  Any notice, request, demand, waiver, consent, approval

                           NON-COMPETITION AGREEMENT
 
    This NON-COMPETITION AGREEMENT made and entered into as of January 12, 1998
by and between Culligan International Company, a Delaware corporation
("Culligan"), and Donald R. Brattain ("Principal").
 
                              W I T N E S S E T H:
 
    WHEREAS, Principal owned a substantial amount of the outstanding the capital
stock of Harmony Brook, Inc., a Minnesota corporation (the "Company") and has
been active in the management of the Company;
 
    WHEREAS, the Board of Directors of the Company have determined that the
merger of the Company with and into Merger Sub (the "Merger") pursuant to an
Agreement and Plan of Merger (the "Merger Agreement") dated as of January 12,
1998 among Company, Parent and a newly-formed wholly owned indirect subsidiary
of Parent ("Merger Sub") would be in the best interest of the Company's
stockholders; and
 
    WHEREAS, but for the agreements of Principal contained herein Parent and
Merger Sub would not be willing to effect the transactions contemplated by the
Merger Agreement;
 
    NOW, THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, Parent and Principal hereby agree as follows:
 
    SECTION 1. COVENANT NOT TO COMPETE.  Principal acknowledges that he has been
involved, at the highest level, in the development, implementation and
management of the business, strategies and plans of the Company, including those
which involve its finances, marketing, operations, industrial relations and
acquisitions. By virtue of Principal's unique and sensitive position, the
employment of Principal by a competitor of Parent represents a serious
competitive danger to Parent, and the use of Principal's talent and knowledge
and information about the Company's business, strategies and plans can and would
constitute a valuable competitive advantage over Parent. In view of the
foregoing, Principal covenants and agrees that for a period of two years
following the date hereof, Principal will not engage or be engaged, in any
capacity, directly or indirectly, including but not limited to, as Principal,
officer, agent, consultant, manager, executive, owner or investor (except as a
passive investor owning less than a 5% interest in a publicly-held corporation)
in any business competitive with the business conducted by the Company as of the
date hereof.
 
    SECTION 2. CONFIDENTIALITY.  Principal agrees to treat as confidential and
not to disclose to anyone, other than Parent and its subsidiaries and affiliated
companies, the affairs of the Company, and he agrees that for a period of three
years after the date hereof he will not, without the prior written consent of
Parent, divulge, furnish or make known or accessible to, or use for the benefit
of, anyone other than Parent and its subsidiaries and affiliated companies, any
information of a confidential nature relating in any way to the business of the
Company or Parent, unless: (i) Principal is required to disclose any such
information by judicial or administrative process or, in the opinion of his
counsel, by other requirements of law, (ii) such information is in the public
domain through no fault of Principal, or (iii) such information has been
lawfully acquired by Principal from other sources unless Principal knows that
such information was obtained in violation of an agreement of confidentiality.
 
                                      A-29
<PAGE>
    SECTION 3. NON-INTERFERENCE.  Principal covenants and agrees that for a
period of three years after the date hereof, he will not:
 
    (a) persuade or attempt to persuade any supplier or customer of the Company
       to cease doing business with the Company, or to reduce the amount of
       business it does with the Company;
 
    (b) persuade or attempt to persuade any potential customer not to do
       business with the Company: or
 
    (c) persuade or attempt to persuade any employee or representative of the
       Company to leave the employ of the Company or any affiliate of the
       Company or to become employed by any person, firm, corporation,
       partnership, association or entity, other than Parent or a subsidiary or
       affiliate of Parent.
 
    SECTION 4. INJUNCTIVE RELIEF.  Principal agrees that in addition to any
other remedy provided at law or in equity or in this Agreement, Parent shall be
entitled to a temporary restraining order and both preliminary and permanent
injunctions restraining Principal from violating any provision of this
Agreement.
 
    SECTION 5. FAILURE TO ENFORCE AND WAIVER.  The failure to insist upon strict
compliance with any of the terms, covenants or conditions of this Agreement
shall not be deemed a waiver of such terms, covenants or conditions, and the
waiver or relinquishment of any right or power under this Agreement at any one
or more times shall not be deemed a waiver or relinquishment or such right or
power at any other time or times.
 
    SECTION 6. ASSIGNMENT.  The rights and obligations of Parent under this
Agreement (i) are assignable by Parent to any parent or subsidiary of Parent, to
any successor by merger to Parent and to any person which acquires all or
substantially all of the assets and business of Parent as a going concern and
(ii) shall inure to the benefit and shall be binding upon the successors and
assigns of Parent and Principal.
 
    SECTION 7. NOTICES.  Any notice, request, demand, waiver, consent, approval
or other communication which is required or permitted hereunder shall be in

                               PROVISIONS OF THE
                       MINNESOTA BUSINESS CORPORATION ACT
                          REGARDING DISSENTERS' RIGHTS
 
302A.471.  RIGHTS OF DISSENTING SHAREHOLDERS
 
    SUBDIVISION 1. ACTIONS CREATING RIGHTS.  A shareholder of a corporation may
dissent from, and obtain payment for the fair value of the shareholder's shares
in the event of, any of the following corporate actions:
 
    (a) An amendment of the articles that materially and adversely affects the
       rights or preferences of the shares of the dissenting shareholder in that
       it:
 
       (1) alters or abolishes a preferential right of the shares;
 
       (2) creates, alters, or abolishes a right in respect of the redemption of
           the shares, including a provision respecting a sinking fund for the
           redemption or repurchase of the shares;
 
       (3) alters or abolishes a preemptive right of the holder of the shares to
           acquire shares, securities other than shares, or rights to purchase
           shares or securities other than shares;
 
       (4) excludes or limits the right of a shareholder to vote on a matter, or
           to cumulate votes, except as the right may be excluded or limited
           through the authorization or issuance of securities of an existing or
           new class or series with similar or different voting rights; except
           that an amendment to the articles of an issuing public corporation
           that provides that section 302A.671 does not apply to a control share
           acquisition does not give rise to the right to obtain payment under
           this section;
 
    (b) A sale, lease, transfer, or other disposition of all or substantially
       all of the property and assets of the corporation, but not including a
       transaction permitted without shareholder approval in section 302A.661,
       subdivision 1, or a disposition in dissolution described in section
       302A.725, subdivision 2, or a disposition pursuant to an order of a
       court, or a disposition for cash on terms requiring that all or
       substantially all of the net proceeds of disposition be distributed to
       the shareholders in accordance with their respective interests within one
       year after the date of disposition;
 
    (c) A plan of merger, whether under this chapter or under chapter 322B, to
       which the corporation is a party, except as provided in subdivision 3;
 
    (d) A plan of exchange, whether under this chapter or under chapter 322B, to
       which the corporation is a party as the corporation whose shares will be
       acquired by the acquiring corporation, if the shares of the shareholder
       are entitled to be voted on the plan; or
 
    (e) Any other corporate action taken pursuant to a shareholder vote with
       respect to which the articles, the bylaws, or a resolution approved by
       the board directs that dissenting shareholders may obtain payment for
       their shares.
 
    SUBD. 2. BENEFICIAL OWNERS.
 
    (a) A shareholder shall not assert dissenters' rights as to less than all of
       the shares registered in the name of the shareholder, unless the
       shareholder dissents with respect to all the shares that are beneficially
       owned by another person but registered in the name of the shareholder and
       discloses the name and address of each beneficial owner on whose behalf
       the shareholder dissents. In that
 
                                      B-1
<PAGE>
       event, the rights of the dissenter shall be determined as if the shares
       as to which the shareholder has dissented and the other shares were
       registered in the names of different shareholders.
 
    (b) The beneficial owner of shares who is not the shareholder may assert
       dissenters' rights with respect to shares held on behalf of the
       beneficial owner, and shall be treated as a dissenting shareholder under
       the terms of this section and section 302A.473, if the beneficial owner
       submits to the corporation at the time of or before the assertion of the
       rights a written consent of the shareholder.
 
    SUBD. 3. RIGHTS NOT TO APPLY.
 
    (a) Unless the articles, the bylaws, or a resolution approved by the board
       otherwise provide, the right to obtain payment under this section does
       not apply to a shareholder of the surviving corporation in a merger, if
       the shares of the shareholder are not entitled to be voted on the merger.
 
    (b) If a date is fixed according to section 302A.445, subdivision 1, for the
       determination of shareholders entitled to receive notice of and to vote
       on an action described in subdivision 1, only shareholders as of the date
       fixed, and beneficial owners as of the date fixed who hold through
       shareholders, as provided in subdivision 2, may exercise dissenters'
       rights.
 
    SUBD. 4. OTHER RIGHTS.  The shareholders of a corporation who have a right
under this section to obtain payment for their shares do not have a right at law
or in equity to have a corporation action described in subdivision 1 set aside
or rescinded, except when the corporate action is fraudulent with regard to the
complaining shareholder or the corporation.

       the successor by merger of that issuer.
 
    (c) "Fair value of the shares" means the value of the shares of a
       corporation immediately before the effective date of the corporate action
       referred to in section 302A.471, subdivision 1.
 
    (d) "Interest" means interest commencing five days after the effective date
       of the corporate action referred to in section 302A.471, subdivision 1,
       up to and including the date of payment, calculated at the rate provided
       in section 549.09 for interest on verdicts and judgments.
 
    SUBD. 2. NOTICE OF ACTION.  If a corporation calls a shareholder meeting at

upon, the notice of the meeting shall inform each shareholder of the right to
dissent and shall include a copy of section 302A.471 and this section and a
brief description of the procedure to be followed under these sections.
 
    SUBD. 3. NOTICE OF DISSENT.  If the proposed action must be approved by the
shareholders, a shareholder who is entitled to dissent under section 302A.471

<PAGE>
    SUBD. 4. NOTICE OF PROCEDURE; DEPOSIT OF SHARES.
 
    (a) After the proposed action has been approved by the board and, if
       necessary, the shareholders, the corporation shall send to all
       shareholders who have complied with subdivision 3 and to all shareholders
       entitled to dissent if no shareholder vote was required, a notice that
       contains:
 
       (1) The address to which a demand for payment and certificated shares
           must be sent in order to obtain payment and the date by which they
           must be received;
 
       (2) Any restrictions on transfer of uncertificated shares that will apply
           after the demand for payment is received;
 
       (3) A form to be used to certify the date on which the shareholder, or
           the beneficial owner on whose behalf the shareholder dissents,
           acquired the shares or an interest in them and to demand payment; and
 
       (4) A copy of section 302A.471 and this section and a brief description
           of the procedures to be followed under these sections.
 
    (b) In order to receive the fair value of the shares, a dissenting
       shareholder must demand payment and deposit certificated shares or comply
       with any restrictions on transfer of uncertificated shares within 30 days
       after the notice required by paragraph (a) was given, but the dissenter
       retains all other rights of a shareholder until the proposed action takes
       effect.
 
    SUBD. 5. PAYMENT; RETURN OF SHARES.
 
    (a) After the corporate action takes effect, or after the corporation
       receives a valid demand for payment, whichever is later, the corporation
       shall remit to each dissenting shareholder who has complied with
       subdivisions 3 and 4 the amount the corporation estimates to be the fair
       value of the shares, plus interest, accompanied by:
 
       (1) The corporation's closing balance sheet and statement of income for a
           fiscal year ending not more than 16 months before the effective date
           of the corporate action, together with the latest available interim
           financial statements;
 
       (2) An estimate by the corporation of the fair value of the shares and a
           brief description of the method used to reach the estimate; and
 
       (3) A copy of section 302A.471 and this section, and a brief description
           of the procedure to be followed in demanding supplemental payment.
 
    (b) The corporation may withhold the remittance described in paragraph (a)
       from a person who was not a shareholder on the date the action dissented
       from was first announced to the public or who is dissenting on behalf of
       a person who was not a beneficial owner on that date. If the dissenter
       has complied with subdivisions 3 and 4, the corporation shall forward to
       the dissenter the materials described in paragraph (a), a statement of
       the reason for withholding the remittance, and an offer to pay to the
       dissenter the amount listed in the materials if the dissenter agrees to
       accept that amount in full satisfaction. The dissenter may decline the
       offer and demand payment under subdivision 6. Failure to do so entitles
       the dissenter only to the amount offered. If the dissenter makes demand,
       subdivisions 7 and 8 apply. If the dissenter makes demand, subdivisions 7
       and 8 apply.
 
    (c) If the corporation fails to remit payment within 60 days of the deposit
       of certificates or the imposition of transfer restrictions on
       uncertificated shares, it shall return all deposited certificates and
       cancel all transfer restrictions. However, the corporation may again give
       notice under subdivision 4 and require deposit or restrict transfer at a
       later time.
 
                                      B-3
<PAGE>
    SUBD. 6. SUPPLEMENTAL PAYMENT; DEMAND.  If a dissenter believes that the
amount remitted under subdivision 5 is less than the fair value of the shares
plus interest, the dissenter may give written notice to the corporation of the
dissenter's own estimate of the fair value of the shares, plus interest, within
30 days after the corporation mails the remittance under subdivision 5, and
demand payment of the difference. Otherwise, a dissenter is entitled only to the
amount remitted by the corporation.
 
    SUBD. 7. PETITION; DETERMINATION.  If the corporation receives a demand
under subdivision 6, it shall, within 60 days after receiving the demand, either
pay to the dissenter the amount demanded or agreed to by the dissenter after
discussion with the corporation or file in court a petition requesting that the
court determine the fair value of the shares, plus interest. The petition shall
be filed in the county in which the registered office of the corporation is
located, except that a surviving foreign corporation that receives a demand
relating to the shares of a constituent domestic corporation shall file the
petition in the county in this state in which the last registered office of the
constituent corporation was located. The petition shall name as parties all
dissenters who have demanded payment under subdivision 6 and who have not
reached agreement with the corporation. The corporation shall, after filing the
petition, serve all parties with a summons and copy of the petition under the
rules of civil procedure. Nonresidents of this state may be served by registered
or certified mail or by publication as provided by law. Except as otherwise
provided, the rules of civil procedure apply to this proceeding. The
jurisdiction of the court is plenary and exclusive. The court may appoint
appraisers, with powers and authorities the court deems proper, to receive
evidence on and recommend the amount of the fair value of the shares. The court
shall determine whether the shareholder or shareholders in question have fully
complied with the requirements of this section, and shall determine the fair
value of the shares, taking into account any and all factors the court finds
relevant, computed by any method or combination of methods that the court, in
its discretion, sees fit to use, whether or not used by the corporation or by a
dissenter. The fair value of the shares as determined by the court is binding on
all shareholders, wherever located. A dissenter is entitled to judgment in cash
for the amount by which the fair value of the shares as determined by the court,
plus interest, exceeds the amount, if any, remitted under subdivision 5, but
shall not be liable to the corporation for the amount, if any, by which the
amount, if any, remitted to the dissenter under subdivision 5 exceeds the fair
value of the shares as determined by the court, plus interest.
 
    SUBD. 8. COSTS; FEES; EXPENSES.
 
    (a) The court shall determine the costs and expenses of a proceeding under
       subdivision 7, including the reasonable expenses and compensation of any
       appraisers appointed by the court, and shall assess those costs and
       expenses against the corporation, except that the court may assess part
       or all of those costs and expenses against a dissenter whose action in
       demanding payment under subdivision 6 is found to be arbitrary,
       vexatious, or not in good faith.
 
    (b) If the court finds that the corporation has failed to comply
       substantially with this section, the court may assess all fees and
       expenses of any experts or attorneys as the court deems equitable. These
       fees and expenses may also be assessed against a person who has acted
       arbitrarily, vexatiously, or not in good faith in bringing the
       proceeding, and may be awarded to a party injured by those actions.
 
    (c) The court may award, in its discretion, fees and expenses to an attorney
       for the dissenters out of the amount awarded to the dissenters, if any.

                        OPINION OF JOHN G. KINNARD & CO.
                      REGARDING THE FAIRNESS OF THE MERGER
 
                                      C-1

February 19, 1998
 
Board of Directors
Harmony Brook, Inc.
1030 Lone Oak Road
Suite 110
Eagan, MN 55121
 
Gentlemen:
 
    You have requested our opinion as to the fairness, from a financial point of
view, to the common stock shareholders of Harmony Brook, Inc. (the "Company") of
the consideration to be received pursuant to the Agreement and Plan of Merger
and Reorganization (the "Merger Agreement") by and among Culligan International
Company (Culligan International), a wholly owned subsidiary of Culligan Water
Technologies, Inc. ("Culligan Water"), Culligan Acquisition Corp., a
newly-formed indirect wholly owned subsidiary of Culligan International ("Merger
Sub"), and the Company. Pursuant to the Merger Agreement, the Merger Sub shall
be merged with and into the Company, with the Company surviving as a wholly
owned subsidiary of Culligan International (the "Merger"). In the Merger, each
issued and outstanding common share of the Company will be converted into the
right to receive $0.545 in cash.
 
    John G. Kinnard and Company, Incorporated, as part of its investment banking
business, is continually engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, private placements, and valuations for estate, corporate and
other purposes. We are familiar with the Company having provided certain
investment banking services to the Company from time to time, including the
Company's initial public offering on April 23, 1993. In connection with the
public offering, Kinnard received warrants to purchase 110,166 shares of Company
common stock at an exercise price of $3.60 per share expiring on April 23, 1998.
In the ordinary course of our business we may actively trade the securities of
the Company for our own account or for the accounts of our customers and,
accordingly, may at anytime hold long or short positions in such securities. We
did not act as financial advisor to the Company in connection with the Merger.
We were not asked to solicit, and accordingly did not solicit, third parties
with respect to potential alternative transactions. For our services in
rendering this opinion, the Company will pay us a fee and indemnify us against
certain liabilities; the fee is not contingent upon consummation of the Merger.
 
    In connection with this opinion, we have reviewed, among other things, the
Merger Agreement dated as of January 12, 1998; Annual Reports to Stockholders
and Annual Reports on Form 10-K of the Company for the three years ended
December 31, 1996, and, in the case of Culligan Water, for the two fiscal years
ending January 31, 1997; certain interim reports to stockholders of the Company
and Culligan Water and certain Quarterly Reports on Form 10-Q of the Company and
Culligan Water; and certain other communications from the Company to
stockholders. We also have held discussions with certain members of the
management and directors of the Company regarding the Company's operations and
its future prospects. In addition, we have reviewed the reported price and
trading activity for the common stock of the Company, compared certain financial
and stock market information for the Company with similar information for
certain companies the securities of which are publicly traded, reviewed the
financial terms of certain recent business combinations in the vended drinking
water industry specifically and in other related industry segments generally,
and performed such other studies and analyses as we considered appropriate.
 
    We have relied upon the accuracy and completeness of all of the financial
and other information reviewed by us, and have assumed such accuracy and
completeness for purposes of this opinion. We have not made an independent
evaluation or appraisal of the assets and liabilities of the Company and we have
