1.  BASIS OF PRESENTATION

The consolidated financial statements included in this Form 10-QSB have been
prepared by the Company, without audit, pursuant to the rules and regulations of
the Securities and Exchange Commission.  Certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been condensed, or omitted,
pursuant to such rules and regulations.  These consolidated financial statements
should be read in conjunction with the financial statements and related
footnotes included in the Company's Annual Report on Form 10-KSB for the year
ended December 31, 1996, previously filed with the Commission. 

The consolidated financial statements presented herein for the three months and
six months ended June 30, 1997 and 1996, reflect, in the opinion of management,
all adjustments (which consist only of normal recurring adjustments) necessary
for a fair presentation of financial position and the results of operations for
the periods presented.  The results of operations for the interim period are not
necessarily indicative of the operating results to be expected for the full
year.


2.  INVENTORIES

3.  EARNINGS PER SHARE

Statement of Financial Accounting Standards (SFAS) No. 128, EARNINGS PER SHARE,
is effective for the Company in the fourth quarter of 1997.  The Company expects
no material impact from 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 within
this Form 10-QSB.  All common stock equivalents are currently anti-dilutive.

FORM 10-QSB
Item 2 - Management's Discussion and Analysis of Results of Operations
        and Financial Condition



RESULTS OF OPERATIONS - SECOND QUARTER AND FIRST SIX MONTHS


REVENUES

Revenues for the second quarter ended June 30, 1997 were $2,175,000 compared
with revenues of $2,107,000 for the quarter ended June 30, 1996, an increase of
three percent.  For the first six months of 1997, revenues were $4,176,000, an
increase of five percent over revenues of $3,989,000 reported for the first six
months of 1996.

Contracted revenue sharing sales for the second quarter of 1997 were $1,526,000.
This represented a two percent increase over the prior year's second quarter
contract revenue sharing sales of $1,498,000.  For the first six months of 1997,
contracted revenue sharing sales were $2,969,000 compared to $2,896,000 for the
first six months of 1996, an increase of three 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 composite growth of its maturing system portfolio.  At June 30, 1997, the
Company had 1,557 domestic customer locations installed, compared with 1,529 at
June 30, 1996.  In addition, the Company had 110 customer locations installed in
Mexico at June 30, 1997 compared with 103 at June 30, 1996.  The total customer
locations at June 30, 1997 was 1,667 compared with 1,632 at June 30, 1996, a two
percent increase.  Domestic revenues for customer locations in place at both
June 30, 1997 and 1996 grew four percent, while the increase in retail gallons
dispensed increased six percent.  The Company has experienced increased
competition for customers in several of its key Midwest markets, primarily in
the form of pricing, which has contributed significantly to a slowing of growth
rates for customer locations and revenue from dispensed gallons of water.

Bottle sales increased 18 percent in the second quarter of 1997 to $565,000 from
$480,000 for the comparable second quarter of 1996.  Bottle sales increased 13
percent for the first six months of 1997 to $1,030,000 compared to $912,000 in
the first six 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 nine percent in the comparable second quarters
from $277,000 in 1996 to $251,000 in 1997.  In the first six months Premium
Bottle Sales decreased from $513,000 in 1996 to $512,000 in 1997.  Wholesale
Bottle Sales increased by 55 percent in the second quarter ($203,000 in 1996 to
$314,000 in 1997) and 30 percent in the first six months ($399,000 in 1996 to
$518,000 in 1997) of 1997.  The 


                                          6
<PAGE>

second quarter decrease in Premium Bottle Sales is due to changes in customer
locations that were precipitated by increased competition, as well as brief
periods when certain routes went uncovered as a result of changes in personnel. 
The increases in Wholesale Bottles are a result of continued emphasis to rebuild
and grow 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 in 1997.


GROSS MARGIN

The Company's total gross margin for the second quarter and first six months of
1997 was 50 and 51 percent, respectively, of revenues compared with 53 percent
of revenues for the second quarter and first six months of 1996.  These
decreases reflect primarily the impact of competition and increased product
quality testing in the Company's core business segment, contracted revenue
sharing.

The gross margin for contracted revenue sharing for the second quarter of 1997
was 58 percent of related revenues and 59 percent of related revenues for the
first six months of 1997.  The comparable gross margins for 1996 were 62 and 61
percent of related revenues for the second quarter and first six months,
respectively.  These decreases are related to two factors.  First, competition
has forced pricing concessions resulting in lower sales revenues per gallon. 
Second, as a way to further assure product quality and distinguish itself from
competition, the Company has increased the frequency of water testing and its
related costs.  The Company expects the margin in this segment to remain
relatively stable for the balance of 1997.

The gross margins for bottle sales were 33 percent of related revenues in both
the second quarter of 1997 and first six months of 1997.  These margins compare
to 32 percent of related revenues in the second quarter of 1996 and 33 percent
of related revenues in the first six months of 1996.

The gross margin for equipment sales was 24 percent of related revenues in the
second quarter of 1997 compared to 21 percent of related revenues in the second
quarter of 1996.  For the first six months of 1996 and 1997 the gross margin for
equipment sales was 24 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).


SELLING, GENERAL AND ADMINISTRATIVE (S,G & A) EXPENSES

Field office S,G & A expenses were $633,000 in the second quarter of 1997, a two
percent increase from field office expense of $623,000 in the comparable second
quarter of 1996.  For the first six months of 1997 and 1996 field office
expenses were $1,276,000 and $1,291,000, respectively, a decrease of one
percent.  Compensation expense decreased due to employee turnover offset by
increased vehicle expenses due to the Company's aging fleet for the second 


                                          7
<PAGE>

quarter and first six months of 1997.  No new geographic territories were
entered for all periods presented, although two service routes were added in
existing territories.

Corporate S,G & A expenses were $390,000 in the second quarter of 1997, a three
percent decrease from corporate expenses of $401,000 in the second quarter of
1996.  For the first six months of 1997 corporate S,G & A expenses were $833,000
compared to $793,000 in the first six months of 1996, a five percent increase. 
This increase in the first six months of 1997 is primarily attributable to
increased Mexican subsidiary expenses related to added personnel and a high
inflation environment.


OPERATING INCOME AND NET LOSS

Operating income is reported for all periods presented.  Other expense, the only
line item between operating profit and net loss, consisted primarily of net
interest expense for all periods presented.

balances of the Company's Mexican Subsidiary unless explicitly stated otherwise.

LIQUIDITY AND CAPITAL RESOURCES

The Company had net cash provided by operating activities of $148,000 in the
second quarter of 1997 compared to $131,000 of net cash provided by operating
activities in the second quarter of 1996.  In the first six months of 1997 the
Company had $312,000 of net cash provided by operations compared to $262,000 of
net cash provided by operating activities in the first six months of 1996.  The
primary contributor to the improvement in net cash provided by operating
activities in both the second quarter and first six months of 1997 was an
increase in accounts payable.  The increase in accounts payable was offset by an
increase in 


                                          8

accounts receivable.  Cumulative changes in all other operating activity areas
were small compared to the changes in accounts payable and accounts receivable
for all periods presented.

The Company invested $400,000 in property and equipment in the second quarter of
1997, an increase of 65 percent from the $242,000 invested in the second quarter
of 1996.  For the first six months of 1996 and 1997 the Company invested
$719,000 in property and equipment. The first six months of 1996 included a
$135,000 buy-out of leased equipment.  After adjusting for this lease buy-out in
the first six months of 1996, the remaining investment in property and equipment
for all periods presented consisted primarily of both the manufacture of new
Harmony Brook-Registered Trademark- Premium Drinking Water systems and the
refurbishment of existing systems.  The increase in investment of property and
equipment is primarily driven by extensive capital refurbishment of the
Company's older systems.

On June 30, 1997, the Company entered into a sale/leaseback agreement with a
shareholder and board member for dispensing equipment.  Under the terms of the
agreement, ten systems were sold for $63,450 and were leased back by the Company
pursuant to a five-year operating lease for placement and operation in one
supermarket chain.  This lease requires a monthly payment of $1,400 and requires
the Company to service and maintain the equipment.  Deferred income of $21,000
is being amortized as a reduction of cost of revenues on a straight-line basis
over the lease term.
 
The Company currently does not have any borrowing capacity available under its
credit facilities. To maintain the Company's current growth strategy, management
believes the Company will need to raise additional financing by late 1997. 
While the Company believes it will be able to obtain additional financing, there
can be no assurance that such financing will be available or available on terms
acceptable to the Company.  In the event such financing is not available, the
Company has the ability to revise its growth strategy to decrease or eliminate
further investment in dispensing equipment which is the primary use of the
Company's cash flows.
