                ANTHONY & SYLVAN POOLS CORPORATION AND SUBSIDIARY
         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(1)        BASIS OF PRESENTATION

                Anthony & Sylvan Pools Corporation and Subsidiary (the
           "Company") is among the largest residential in-ground concrete pool
           sales and installation businesses in the United States and operates
           in one business segment.

                On August 10, 1999, a third party (the "Acquiring Party")
           acquired Essef Corporation ("Essef") the Company's former parent, in
           a merger transaction that included the Company being split-off to
           Essef's common shareholders through a taxable distribution of 100% of
           the Company's shares as part of the merger consideration. The
           split-off was accomplished through the distribution of 0.25 shares of
           common stock for every share of Essef common stock held at the time
           of the distribution. Immediately prior to the split-off, the Company
           amended its articles of incorporation to provide for the issuance of
           up to 1,000,000 serial preferred shares and 29,000,000 shares of
           common stock.

                The Company, Essef and Acquiring Party have entered into various
           agreements that provide for administrative services, tax sharing and
           indemnification (the "Agreements"). Among other things, these
           Agreements provided for the Company to pay a dividend of $17,000,000,
           subject to certain adjustments, to Essef with the balance of the
           inter-company payable being contributed to capital retroactive to the
           split-off date. The potential adjustments to the $17,000,000
           primarily related to the net tax benefit, as defined in the
           Agreements, realized by Essef from the exercise of employee stock
           options net of the corporate tax payable from the split-off. Pursuant
           to the Agreements, the calculation of adjustments has been completed
           and the Company was not required to pay Essef any of the $17,000,000.
           As such all of the Company's debt to Essef, which totaled $27,241,000
           at the date of the split-off, was contributed to the Company's
           capital increasing shareholders' equity to approximately $34,700,000
           at the date of the split-off.

                Company management believes that for the periods presented
           herein in which the Company was owned by Essef that the financial
           statements reflect all material expenses of the Company as if it was
           organized as a stand-alone legal entity including specifically
           identifiable costs incurred by Essef on behalf of, and charged to,
           the Company.

(2)        INTERIM UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                The accompanying condensed consolidated balance sheet as of
           March 31, 2000 and statements of operations and cash flows for the
           three-month periods ended March 31, 2000 and 1999 are unaudited. In
           the opinion of management, these interim unaudited condensed
           consolidated financial statements have been prepared on the same
           basis as the audited financial statements for the year ended December
           31, 1999 and include all adjustments, consisting of only normal and
           recurring adjustments, necessary for the fair presentation of the
           interim period. The disclosures in the notes related to these interim
           unaudited condensed consolidated financial statements are also
           unaudited. The unaudited condensed consolidated statements of
           operations for the three-month period ended March 31, 2000 are not
           necessarily indicative of the results to be expected for the full
           year.

(3)        EARNINGS PER SHARE

                Basic earnings per share is computed by dividing net income by
           the weighted average number of common shares outstanding. Diluted
           earnings per share is based on the combine weighted average number of
           shares outstanding including the assumed exercise or conversion of
           options. The treasury stock method is used in computing diluted
           earnings per share. For the periods prior to the split-off from Essef
           earnings per share is calculated based on the number of shares that
           would have been outstanding assuming the split-off had occurred at
           the beginning of the period shown. The calculations are as follows
           (In thousands except per share data):

                                            THREE-MONTHS ENDED

          (a)  Due to the net loss reported in both periods, the share base used
               in calculating net income/(loss) per diluted share does not
               include the effect of common share equivalents, as its effect
               would be anti-dilutive.

(4)        RELATED PARTY TRANSACTIONS

                With the exception of certain capitalized lease obligations,
           prior to June 30, 1999 the Company did not have external sources of
           borrowings, and as such relied upon Essef as its primary source of
           funding. Interest was charged at an average rate of 10.6% for the
           three-month period ended March 31, 1999. Total interest charges on
           the inter-company account for the three-months ended March 31, 1999
           were $1,085,000. At the date of the split-off the intercompany
           account was contributed to capital (see note 1).

(5)          DEBT

                On August 10, 1999, the Company entered into a $35 million
             revolving credit facility ("Credit Facility") with a group of
             banks. The Credit Facility, secured by the assets of the Company,
             matures August 10, 2002 and may be extended in one-year increments
             with the approval of the bank group. The Company's borrowing
             capacity and interest rates under the Credit Facility are based on
             its profitability and leverage. Interest rates are charged at
             increments over either Prime or Libor rates. In addition a 37.5
             basis points commitment fee is payable on the total amount of the
             unused commitment. As of March 31, 2000, the effective rate on all
             outstanding borrowings under the Credit Facility was 7.7% and the
             available borrowings were $16.2 million. The Company is in
             compliance with all of its debt covenants under the Credit
             Facility.

(6)          LITIGATION

                Certain claims, suits and complaints arising in the ordinary
             course of business have been filed or are pending against the
             Company. In the opinion of management, the results of all such
             matters will not have a material adverse effect on the Company's
             financial position, results of operations or liquidity.

(7)          SUBSEQUENT EVENTS

                On May 2, 2000, the Board of Directors authorized a 10% stock
             dividend to be distributed on or about May 30, 2000 to shareholders
             of record on May 16, 2000. The consolidated financial statements
             have not been restated to reflect the number of shares outstanding
             following the dividend.

ITEM 2.

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                   OPERATIONS

                 THREE MONTHS ENDED MARCH 31, 2000 COMPARED WITH
                        THREE MONTHS ENDED MARCH 31, 1999

Net sales of $30.4 million for the three-months ended March 31, 2000 increased
15.0% from $26.4 million for the same period in fiscal 1999. The increase was
attributable to increases in production and increases in average selling prices.

Gross profit increased to $6.5 million in 2000 from $5.7 million in 1999 as a
result of the increase in net sales. Gross profit as a percentage of sales for
the three months decreased slightly from 21.6% of net sales to 21.2%.

Operating expenses consisting of selling and administrative expenses increased
by $0.2 million to $9.7 million in 2000 from $9.5 million in 1999. As a
percentage of sales, operating expenses decreased from 36.0% in 2000 to 31.8% in
the current period. The percentage of sales decrease was primarily attributable
to tighter spending controls implemented in 2000 during the seasonally slow
first quarter of the year.

Interest and other expense decreased $0.9 million from $1.1 million in 1999 to
$0.2 million in the current period. Interest was paid on external borrowings in
2000, while the interest paid in 1999 was paid to the Company's former Parent,
Essef Corporation, through an intercompany borrowing arrangement.

As a result of the above items, adjusted for the impact of federal and state
taxes, the net loss for the three month period decreased from $3.0 million in
1999 to $2.1 million in 2000, and the net loss per diluted share decreased $0.08
per share from $0.88 in 1999 to $0.80 in 2000.

                         LIQUIDITY AND CAPITAL RESOURCES

Cash flow from operating activities was $3.6 million in each of the three month
periods ended March 31, 2000 and 1999, while cash used in investing activities
increased $0.1 million to $0.8 million in 2000 compared with $0.7 million in
1999. The excess of cash from operating activities over cash used in investing
activities combined with the proceeds from the sale of treasury shares was used
to reduce external borrowings by $2.5 million in the three months ended March
31, 2000.

On August 10, 1999, a third party acquired the Company's former Parent, Essef
Corporation ("Essef"), in a merger transaction that included the Company being
split-off to Essef's common shareholders as part of the merger consideration. In
accordance with the terms of the merger agreement, subsequent to June 30, 1999
the Company separated its cash management activities from Essef. Therefore, the
Company could no longer be advanced funds from Essef while retaining its
after-tax cash flow after such date. Additionally, the Company was not required
to pay Essef any of the $17,000,000 that might have been due under certain
adjustment mechanisms related to the Company's split-off from Essef. As such,
all of the Company's debt to Essef, which totaled $27,241,000 at the date of the
split-off, was contributed to the Company's capital at the date of the
split-off.

On August 10, 1999, the Company entered into a $35 million revolving credit
facility ("Credit Facility") with a group of banks. The Credit Facility, secured
by the assets of the Company, matures August 10, 2002 and may be extended in
one-year increments with the approval of the bank group. The Company's borrowing
capacity and interest rates under the Credit Facility are based on its
profitability and leverage. Interest rates are charged at increments over either
Prime or Libor rates. In addition, a 37.5 basis points commitment fee is payable
on the total amount of the unused commitment. As of March 31, 2000, the
effective

                                       9
<PAGE>   10

rate on all outstanding borrowings under the Credit Facility was 7.7% and the
available borrowings were $16.2 million. The Company is in compliance with all
of its debt covenants under the Credit Facility.

The Company believes that existing cash and cash equivalents, internally
generated funds and funds available under its line of credit will be sufficient
to meet its needs.

            QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The Company is exposed to various market risks, including changes in pricing of
equipment, materials and contract labor, and interest rates. Market risk is the
potential loss arising from adverse changes in market rates and prices, such as
commodity prices and interest rates. The Company does not enter into financial
instruments to manage and reduce the impact of some of these risks. Further, the
Company does not enter into derivatives or other financial instruments for
trading or speculative purposes.

The Company is exposed to cash flow and fair value risk arising out of changes
in interest rates with respect to its long-term debt. Information with respect
to the Company's principal cash flows and it's weighted average interest rates
on long-term debt at March 31, 2000 is included in the Condensed Consolidated
Financial Statements.

                                YEAR 2000 MATTERS

The Company did not experience any significant malfunction or errors in its
operating or business systems when the date changed from 1999 to 2000. Based on
operations since January 1, 2000, the Company does not expect any significant
impact to its ongoing business as a result of the "Year 2000 issue." However it
is possible that the full impact of the date change has not been fully
recognized. In addition, the Company is not aware of any significant Year 2000
or similar problems that have arisen for its suppliers or service providers, and
does not believe it would have difficulty securing alternate sources of supply
in the event that any of its current suppliers or service providers do
experience Year 2000 or similar problems.

The Company's expenditure on Year 2000 readiness efforts was not material. These
efforts included replacing or upgrading outdated, noncompliant hardware and
software as well as identifying and remediating Year 2000 problems.

                           CYCLICALITY AND SEASONALITY

The Company believes that the in-ground swimming pool industry is strongly
influenced by general economic conditions and tends to experience periods of
decline during economic downturns. Since the majority of the Company's swimming
pool installation purchases are financed, pool sales are particularly sensitive
to interest rate fluctuations and the availability of credit. A sustained period
of high interest rates could result in declining sales, which could have a
material adverse effect on The Company's financial condition and results of
operations.

Historically, approximately 70% of the Company's revenues have been generated in
the second and third quarters of the year, the peak season for swimming pool
installation and use. Conversely, the Company typically incurs net losses during
the first and fourth quarters of the year. Unseasonably cold weather or
extraordinary amounts of rainfall during the peak sales season can significantly
reduce pool purchases. In addition, unseasonably early or late warming trends
can increase or decrease the length of the swimming pool season, significantly
affecting sales and operating profit.
