for complete financial statements. In the opinion of management, all adjustments
(consisting of normal recurring accruals) considered necessary for a fair
presentation have been included. Operating results for the ninety-five day
period ended April 5, 1998 are not necessarily indicative of the results that
may be expected for the year ending January 3, 1999, or any other period. For
further information, refer to the financial statements and footnotes thereto for
the year ended December 31, 1997 included in the Company's latest annual report
on Form 10-K.

In 1998, the Company's fiscal year will end on the Sunday closest to December 31
(January 3, 1999) and each quarter ends on the last Sunday of a thirteen week
period. As a result, the first quarters ended April 5, 1998 and March 31, 1997
included 95 and 90 days, respectively. In the Company's opinion, this difference
in days does not materially affect the comparability of the financial results of
the periods presented.

Note B -- Inventory

The components of inventory consist of the following:

Note C -- Net Loss Per Share

In 1997, the Financial Accounting Standards Board (FASB) issued Statement No.
128, EARNINGS PER SHARE. Statement 128 replaced the calculation of primary and
fully diluted earnings per share with basic and diluted earnings per share.
Unlike primary earnings per share, basic earnings per share excludes any
dilutive effects of options, warrants and convertible securities. Diluted
earnings per share is very similar to the previously reported fully diluted
earnings per share. All earnings per share amounts for all periods have been
presented, and where appropriate, restated to conform to Statement 128
requirements.


<PAGE>


Note D -- Accounting Statements

In 1997, the FASB issued Statements No. 130, REPORTING COMPREHENSIVE INCOME, and
No. 131, DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION,
effective for fiscal years beginning after December 15, 1997. The adoption by
the Company of these Statements in January 1998 did not have a material impact
on the Company's financial statements.

Note E -- Subsequent Events

The Company completed a public offering of Common Stock on April 28, 1998
netting approximately $33,200,000 from the sale of 1,190,000 shares. The Common
Stock was priced at $30.00 per share. All of the shares were sold by the
Company. The underwriters have informed the Company that on May 18, 1998 they
will purchase an additional 178,500 shares of Common Stock pursuant to the
exercise of their overallotment option, which will result in additional net
proceeds to the Company of approximately $5,000,000.

Item 2.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

                  (Ninety-five Day Period ended April 5, 1998)

RESULTS OF OPERATIONS:

Net sales for the ninety-five day period ended April 5, 1998 increased 66
percent over sales for the ninety day period ended March 31, 1997. This growth
was due to increased sales of the Company's existing PUR household water
filtration products and the introduction of new products for the household
market. In March 1998, the Company began shipping the PUR PLUS pitcher,
which is one of its new pour-through products introduced at the International
Housewares Show in January. The Company also continued to increase its
distribution base including the addition of Rite Aid, a nationwide drug store
chain, adding over 2,000 new retail outlets at which PUR products may be
purchased by consumers. PUR water filter systems and replacement filters
are now available at over 28,000 retail outlets nationwide.

Gross profit margin for the period ended April 5, 1998 was 47.6 percent compared
to 40.2 percent for the period ended March 31, 1997. This improvement was due to
the implementation of automated manufacturing and assembly processes, reductions
in costs of materials, and an increase in sales of higher margin household
products including replacement filter cartridges as a percentage of total sales.

Selling, general and administrative expenses increased to $7.9 million for the
period ended April 5, 1998 from $5.2 million for the period ended March 31,
1997, representing 45.7% and 49.8% of net sales, respectively. The increase in
selling, general and administrative expenses was attributable primarily to
advertising and promotional expenses related to the continued rollout and
expansion of the Company's line of household water filters. While selling
expenses are expected to be above 1997 levels throughout the remainder of the
year to support the continued roll-out of the household drinking water systems
and product line extensions, they are expected to remain flat as a percentage of
sales.

Research and development expense increased to $1,011,000 for the period ended
April 5, 1998,compared to $754,000 for the period ended March 31, 1997,
reflecting the Company's commitment towards developing new products and
technology. Development of product line extensions and other new products will
require continued emphasis and increased spending on research and development.

Other expenses increased to $540,000 for the period ended April 5, 1998 compared
to $143,000 for the period ended March 31, 1997. The increase is due to payments
of interest on long-term debt and the Company's line of credit as well as no
interest income corresponding to decreased balances of cash, cash equivalents
and marketable securities.

The Company's effective income tax rate was 15% for the period ended April 5,
1998, compared to 0% for the period ended March 31, 1997. The Company has a
$1,512,000 net deferred tax asset primarily related to net operating loss
carryforwards. The Company has

<PAGE>


recorded a valuation allowance for the majority of its deferred tax asset due to
the uncertainty of future realization.


LIQUIDITY AND CAPITAL RESOURCES:

Cash used in operations was $4,295,000 for the period ended April 5, 1998,
compared to cash used in operations of $4,657,000 for the period ended March 31,
1997. Cash was used to fund operations and increase the level of inventories and
receivables, as well as reduce the level of accounts payable and accrued
expenses.

Capital expenditures were $2,130,000 for the period ended April 5, 1998,
compared to $1,431,000 for the period ended March 31, 1997. The capital
expenditures were primarily to purchase tooling and manufacturing equipment for
both periods. The Company anticipates increased expenditures for tooling and
manufacturing equipment purchases associated with new product introductions and
an increase in overall production capacity.

The Company had $13,206,000 of bank debt at April 5, 1998, as compared to
$7,161,000 at December 31, 1997. This credit facility, established in March 1997
and amended in March 1998, provides for total borrowings of up to $25.0 million,
secured by equipment, inventory, receivables and intangibles. The credit
facility consists of $15.0 million discretionary working capital line of credit,
limited to eligible receivables and inventory, which bears interest at the
bank's reference rate plus 0.75%, and a $10.0 million equipment loan which bears
interest at the bank's reference rate plus 1.25%. Borrowings under the equipment
loan are made in increments of $2.0 million and are payable over a 48-month
period commencing the first full month following each separate advance. Other
borrowings under the credit facility are due on demand. Pursuant to the
Company's agreement with GS Group, borrowings under the bank credit facility
were limited to $10.0 million in 1997 and are limited to $12.5 million in 1998.
However, the Company received waivers from GS Group allowing it to borrow up to
$14.0 million under the credit facility during the fourth quarter of 1997 and up
to $16.0 million in 1998.

The Company completed a public offering of Common Stock on April 28, 1998
netting approximately $33,200,000 from the sale of 1,190,000 shares. The Common
Stock was priced at $30.00 per share. All of the shares were sold by the
Company. The underwriters have informed the Company that on May 18, 1998 they
will purchase an additional 178,500 shares of Common Stock pursuant to the
exercise of their overallotment option, which will result in additional net
proceeds to the Company of approximately $5,000,000.

Management believes that anticipated cash flows from operations, funds available
through its bank credit facility, and the net proceeds from its public offering
of Common Stock will provide sufficient capital resources for current operations
and planned product introductions.

The Company has not paid cash dividends. The Board of Directors currently
intends to retain all earnings for expansion of the Company's business.

PART II    OTHER INFORMATION

Item 1.    Legal Proceedings

           As previously reported, the Company is a defendant in a civil
           proceeding initiated in April 1997 by UltraPure Systems, Inc., a
           subsidiary of Culligan Water Technologies, Inc., which asserts that
           the Company has infringed an UltraPure patent on a faucet-mounted
           filter system. On April 16, 1998, the Court granted the Company's
           motion for summary judgment, dismissing all of UltraPure's claims.
           The Court's order is subject to appeal for a period of thirty days
           from the date the judgment is entered. The Company believes it does
           not infringe UltraPure's patent and, if the order for summary
           judgment is appealed, the Company intends to defend vigorously its
           right to market and sell these products.

Item 2.    Changes in Securities and Use of Proceeds

           On February 3, 1998, the Board of Directors of the Company adopted an
           amendment to the Rights Agreement between the Company and Norwest
           Bank Minnesota, National Association, as Rights Agent. The amendment
           provides that a person who becomes the beneficial owner of 15% or
           more (formerly 20% or more) of the shares of Common Stock of the
           Company then outstanding will be deemed to be an "Acquiring Person,"
           except that Brian F. Sullivan, William F. Wanner, Jr. or Goldman,
           Sachs & Co. and their respective affiliates may, in addition to
           shares beneficially owned on February 3, 1998, acquire shares that
           represent up to 3% of the shares of Common Stock outstanding without
           being deemed to be an "Acquiring Person." The amendment also provides
           that decisions to redeem the Rights or to adopt certain amendments to
           the Rights Agreement may be made only by "Continuing Directors," as
           such term is defined in the amendment.
