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

(1)        BASIS OF PRESENTATION

                Anthony & Sylvan Pools Corporation and Subsidiaries (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.

(2)        INTERIM UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                The accompanying condensed consolidated balance sheet as of
           March 31, 2001 and statements of operations and cash flows for the
           three-month periods ended March 31, 2001 and 2000 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, 2000 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, 2001 are not
           necessarily indicative of the results to be expected for the full
           year. Financial statements should be read in conjunction with the
           audited financial statements included in the annual report on Form
           10-K.

(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 combined 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. The calculations are as follows (in thousands
           except per share data):

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

(4)      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 is 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, 2001, the
         effective rate on all outstanding borrowings under the Credit Facility
         was 8.375% and the available borrowings were $17.0 million. The Company
         is in compliance with all of its debt covenants under the Credit
         Facility.

(5)      CAPITAL STOCK

                  On January 5, 2001, based on the authorization of its Board of
         Directors, the Company purchased a block of 250,000 shares of its
         common stock, in a private transaction at $8.00 per share.

(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)      NEW ACCOUNTING STANDARDS

                  Statement of Financial Accounting Standards No. 133,
         Accounting for Derivative Instruments and Hedging Activities,"
         establishes accounting and reporting standards for derivative
         instruments, including certain derivative instruments embedded in other
         contracts and for hedging activities. The Company adopted the statement
         effective January 1, 2001. The adoption of SFAS No. 133 did not have a
         significant impact on the financial position or results of operations
         of the Company because the Company does not have derivative
         instruments.

(8)      SUBSEQUENT EVENTS

                  On May 4, 2001, the Board of Directors authorized a 10% stock
         dividend to be distributed on or about May 30, 2001 to shareholders of
         record on May 16, 2001. The consolidated financial statements have not
         been restated to reflect the number of shares outstanding following the
         dividend.

INDEPENDENT ACCOUNTANTS' REPORT

To the Shareholders and Board of Directors of
Anthony & Sylvan Pools Corporation and Subsidiary
Mayfield Village, Ohio


We have reviewed the accompanying condensed consolidated balance sheet of
Anthony & Sylvan Pools Corporation and Subsidiary (the "Company") as of March
31, 2001, and the related condensed consolidated statements of operations and
cash flows for the three-month periods ended March 31, 2001 and 2000. These
consolidated financial statements are the responsibility of the Company's
management.

We conducted our reviews in accordance with standards established by the
American Institute of Certified Public Accountants. A review of interim
financial information consists principally of applying analytical procedures to
financial data and of making inquiries of persons responsible for financial and
accounting matters. It is substantially less in scope than an audit conducted in
accordance with auditing standards generally accepted in the United States of
America, the objective of which is the expression of an opinion regarding the
financial statements taken as a whole. Accordingly, we do not express such an
opinion.

Based on our reviews, we are not aware of any material modifications that should
be made to such condensed consolidated financial statements for them to be in
conformity with accounting principles generally accepted in the United States of
America.

We have previously audited, in accordance with auditing standards generally
accepted in the United States of America, the consolidated balance sheet of the
Company as of December 31, 2000, and the related statements of operations,
shareholders' equity, and cash flows for the year then ended (not presented
herein) and in our report dated March 28, 2001 we expressed an unqualified
opinion on those financial statements. In our opinion, the information set forth
in the accompanying condensed consolidated balance sheet as of December 31, 2000
is fairly stated, in all material respects, in relation to the balance sheet
from which it has been derived.

ITEM 2.

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

                 THREE MONTHS ENDED MARCH 31, 2001 COMPARED WITH
                        THREE MONTHS ENDED MARCH 31, 2000

Net sales of $26.1 million for the three-months ended March 31, 2001 decreased
14.2% from $30.4 million for the same period in fiscal 2000. The decrease was
primarily attributable to decreases in production as a result of winter weather
conditions which was worse than was experienced in the last several years, and
which had a major impact on our ability to install swimming pools in many of our
markets, offset by increases in average selling prices compared with a year
earlier.

Gross profit decreased to $5.0 million in 2001 from $6.5 million in 2000 as a
result of the decrease in net sales. Gross profit as a percentage of sales for
the three months decreased from 21.2% of net sales to 19.1% as the lower
production volume resulted in fixed construction costs being spread over a lower
revenue base.

Operating expenses, consisting of selling and administrative expenses, increased
by $0.3 million to $10.1 million in 2001 from $9.8 million in 2000. The increase
was primarily attributable to higher administrative expenses related to efforts
at improving our infrastructure and execution, partially offset by a credit for
non-cash deferred compensation related to the Company's long-term incentive plan
which is accounted for as a variable plan, based on changes in the Company's
stock price.

As a result of the above items, adjusted for the impact of federal and state
taxes, the net loss for the three month period increased $1.0 million from $2.2
million in 2000 to $3.2 million in 2001. The net loss per share, which benefited
from a higher number of shares outstanding following a stock option exercise in
the fourth quarter of 2000, increased $(0.13) per share from $(0.70) in 2000 to
$(0.83) in 2001.

                         LIQUIDITY AND CAPITAL RESOURCES

Cash flow from operating activities was $2.6 million for the three-months ended
March 31, 2001 compared with $3.6 million in the same period in fiscal 2000. The
decrease is primarily attributable to the higher net loss in 2000. Cash used in
investing activities increased $0.9 million to $1.7 million in 2001 from $0.8
million in 2000 as a result of increased expenditure related to the Company's
investment in new technology which commenced in the fourth quarter of 2000. The
excess of cash from operating activities over cash used in investing activities,
combined with $1.0 million in proceeds from long-term debt, was used to acquire
$2.0 million of treasury shares in 2001.

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

                                       10
<PAGE>   11

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 8.375% and the available borrowings were $17.0 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, 2001 is included in the Condensed Consolidated
Financial Statements.

The Company's financial results have been impacted by fluctuations in its stock
price, as a portion of the Company's Long-Term Incentive Plan was treated as a
variable versus a fixed stock option award plan.

                           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, results of
operations or liquidity.

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.
