Because they cover interim periods, the statements and related notes to the financial statements do not include all disclosures and notes normally provided in annual financial statements and, therefore, should be read in conjunction with the Aqua America Annual Report on Form 10-K for the year ended December 31, 2004 and the Quarterly Report on Form 10-Q for the quarter ended March 31, 2005. The results of operations for interim periods may not be indicative of the results that may be expected for the entire year. Certain prior year amounts have been reclassified to conform with current year's presentation. Note 2 Stockholders' Equity -------------------- On August 2, 2005, Aqua America's Board of Directors declared a four-for-three common stock split effected in the form of a 33.3% stock distribution for shareholders of record on November 17, 2005. The new shares will be distributed on December 1, 2005. Aqua America's par value of $0.50 per share will not change as a result of the common stock distribution, and as a result, on the distribution date an amount will be transferred from Capital in Excess of Par Value to Common Stock to record the common stock split. Except where noted, the share and per share data contained in this Quarterly Report on Form 10-Q have not been restated to give effect to this stock split. The following table shows the pro forma effect on the Company's historical net income per share: Six Months Ended Three Months Ended June 30, June 30, ---------------------------- --------------------------- 2005 2004 2005 2004 ---------------------------- --------------------------- Pre-split net income per common share, as reported: Basic $ 0.43 $ 0.36 $ 0.23 $ 0.19 Diluted 0.42 0.36 0.23 0.19 Pro forma post-split net income per common share: Basic $ 0.32 $ 0.27 $ 0.17 $ 0.14 Diluted 0.32 0.27 0.17 0.14 Aqua America reports other comprehensive income in accordance with Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive Income."

AQUA AMERICA, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of dollars, except per share amounts) (continued) (UNAUDITED) Note 3 Long-term Debt and Loans Payable -------------------------------- In February 2005, Aqua America issued $30,000 of unsecured notes of which $18,000 are due in 2015 with an interest rate of 5.01% and $12,000 are due in 2020 with an interest rate of 5.20%. The proceeds of this financing were used to refinance existing short-term debt. In May 2005, the Company's Pennsylvania operating subsidiary issued $72,000 of tax-exempt bonds secured by a supplement to the trust indenture relating to its First Mortgage Bonds on the following terms: $22,000 at 4.87% due in 2036, $25,000 at 4.88% due in 2037 and $25,000 at 4.89% due in 2038. Of the $72,000 in proceeds, $22,000 will be used to retire previously issued tax-exempt bonds in August 2005 and the balance of the proceeds are restricted to funding the costs of certain capital projects in 2005 and 2006. Note 4 Net Income per Common Share --------------------------- Basic net income per common share is based on the weighted average number of common shares outstanding. Diluted net income per common share is based on the weighted average number of common shares outstanding and potentially dilutive shares. The dilutive effect of employee stock options is included in the computation of diluted net income per common share. The following table summarizes the shares, in thousands, used in computing basic and diluted net income per common share: Six Months Ended Three Months Ended June 30, June 30, -------------------------- -------------------------- 2005 2004 2005 2004 -------------------------- -------------------------- Average common shares outstanding during the period for basic computation 95,701 92,793 95,889 92,899 Dilutive effect of employee stock options 1,210 1,035 1,234 949 -------------------------- -------------------------- Average common shares outstanding during the period for diluted computation 96,911 93,828 97,123 93,848 ========================== ========================== For the quarter and six months ended June 30, 2005, there were no outstanding employee stock options excluded from the calculation of diluted net income per share as the average market price of the Company's common stock was greater than the options' exercise price. For the quarter and six months ended June 30, 2004, outstanding employee stock options to purchase 581,900 shares of common stock were excluded from the calculation of diluted net income per share as the options' exercise price was greater than the average market price of the Company's common stock during this period. 8

AQUA AMERICA, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of dollars, except per share amounts) (continued) (UNAUDITED) Note 5 Stock-Based Compensation Aqua America currently accounts for stock-based compensation using the intrinsic value method in accordance with APB Opinion No. 25, "Accounting for Stock Issued to Employees." Accordingly, no compensation expense related to granting of stock options has been recognized in the financial statements for stock options that have been granted, as the grant price is equal to the market price on the date of grant. Please refer to Note 8 - Recent Accounting Pronouncements for information concerning changes to Aqua America's accounting for stock-based compensation. Pursuant to the current disclosure requirements of SFAS No. 123, "Accounting for Stock-Based Compensation," as amended by SFAS No. 148, pro forma net income and earnings per share are presented in the following table as if compensation cost for stock-based employee compensation was determined as of the grant date under the fair value method: Six Months Ended Three Months Ended June 30, June 30, ------------------------- ------------------------- 2005 2004 2005 2004 ------------------------- ------------------------- Net income, as reported: $ 41,089 $ 33,446 $ 22,218 $ 17,871 Add: stock-based employee compensation expense included in reported net income, net of tax 209 168 151 136 Less: pro forma expense related to stock options granted, net of tax effects (1,099) (1,082) (596) (593) ------------------------- ------------------------- Pro forma $ 40,199 $ 32,532 $ 21,773 $ 17,414 ========================= ========================= Basic net income per share: As reported $ 0.43 $ 0.36 $ 0.23 $ 0.19 Pro forma 0.42 0.35 0.23 0.19 Diluted net income per share: As reported $ 0.42 $ 0.36 $ 0.23 $ 0.19 Pro forma 0.41 0.35 0.22 0.19 The fair value of options at the date of grant was estimated using the Black-Scholes option-pricing model. 9

AQUA AMERICA, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of dollars, except per share amounts) (continued) (UNAUDITED) Note 7 Water and Wastewater Rates -------------------------- In April 2005, the Company's operating subsidiaries in Illinois and North Carolina's Heater division were granted rate increases designed to increase total revenue on an annual basis by approximately $1,287 and $1,489, respectively. In June 2005, the Company's wastewater subsidiary in Pennsylvania was granted rate increases for three separate systems designed to increase total revenue on an annual basis by approximately $125. In May 2004, the Company's operating subsidiary in Texas filed an application with the Texas Commission on Environmental Quality to increase rates by $11,920 over a multi-year period. The application seeks to increase annual revenues in phases and is accompanied by a plan to defer and amortize a portion of the Company's depreciation, operating and other tax expense over a similar multi-year period, such that the annual impact on operating income approximates the requested amount. The application is currently pending before the Commission, and several parties have joined the proceeding to challenge our rate request. The Company commenced billing for the requested rates and implemented the deferral plan in August 2004, in accordance with authorization from the Texas Commission on Environmental Quality in July 2004. The revenue recognized and the expenses deferred by the Company reflect an estimate of the final outcome of the ruling. As of June 30, 2005, the Company has deferred $7,403 of expenses and recognized $2,475 of revenue that is subject to refund based on the outcome of the final commission order. In the event the Company's request is denied completely or in part, it could be required to refund some or all of the revenue billed to date, and write-off some or all of the regulatory asset for the expense deferral. Based on the Company's review of the present circumstances, no additional reserve or change in estimate adjustments are required for the revenue recognized to date or for the impairment of its regulatory asset. Note 8 Recent Accounting Pronouncements -------------------------------- In May 2005, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 154, "Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20 and FASB Statement No. 3." SFAS No. 154 requires retrospective application to prior periods' financial statements for changes in accounting principle, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 also requires that retrospective application of a change in accounting principle be limited to the direct effects of the change. Indirect effects of a change in accounting principle should be recognized in the period of the accounting change. SFAS No. 154 further requires that a change in depreciation, amortization or depletion method for long-lived, nonfinancial assets be accounted for as a change in accounting estimate effected by a change in accounting principle. Aqua America intends to adopt this standard as required in 2006. 11

AQUA AMERICA, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of dollars, except per share amounts) (continued) (UNAUDITED) In March 2005, the FASB issued FASB Interpretation No. 47, "Accounting for Conditional Asset Retirement Obligations," which clarifies that an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value can be reasonably estimated. The obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and (or) method of settlement. Aqua America intends to adopt this standard as required in 2006. Aqua America is currently evaluating the provisions of this statement and has not yet determined the effect of adoption on its results of operations or financial position. In December 2004, the FASB issued SFAS No. 123R, "Share-Based Payment," which revises SFAS No. 123, "Accounting for Stock-based Compensation," and supersedes APB No. 25, "Accounting for Stock Issued to Employees." In April 2005, the effective date for this standard was changed to require adoption of the standard at the beginning of the next fiscal year after June 15, 2005. As noted in Note 5 - Stock-based Compensation, the Company currently provides pro forma disclosure of its compensation costs associated with the fair value of stock options that have been granted. The Company currently accounts for stock-based compensation associated with stock options using the intrinsic method, and accordingly, no compensation costs have been recognized in its consolidated financial statements. SFAS 123R generally requires that the Company measure the cost of employee services received in exchange for stock-based awards on the grant-date fair value and this cost will be recognized over the period during which an employee provides service in exchange for the award. The fair value of the option grant will be estimated using an option-pricing model. The Company is currently evaluating this standard to determine the impact on its consolidated financial statements, including the selection of an appropriate option-pricing model as permitted under SFAS No. 123R, and the method by which it will adopt SFAS No. 123R. The impact of adoption of SFAS No. 123R on the Company's earnings cannot be predicted at this time because it will depend on a number of variables including the level of share-based payments granted in the future. However, had the Company adopted SFAS No. 123R in prior periods, the impact of the standard would not have been materially different from the impact of SFAS 123 as described in the disclosure of pro forma net income and net income per share in Note 5 - Stock-based Compensation. The Company believes the adoption will have no impact on its overall financial position or cash flow, but will result in the reclassification of related tax benefits from operating cash flow to financing cash flow to the extent these tax benefits exceed the associated compensation cost recognized in the income statement. The Company is currently evaluating the change in the cash flow reporting and has not yet determined the effect of adoption on its cash flow statement presentation. In November 2004, the FASB approved Statement of Financial Accounting Standards ("SFAS") No. 151, "Inventory Costs - An Amendment of ARB No. 43, Chapter 4." SFAS No. 151 requires the exclusion of certain costs from inventories and the allocation of fixed production overheads to inventories to be based on the normal capacity of the production facilities. The standard is effective for the Company for costs incurred after December 31, 2005. The Company believes this statement will not have a material impact on its results of operations or financial position. 12

AQUA AMERICA, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of dollars, except per share amounts) (continued) (UNAUDITED) In November 2004, the FASB issued SFAS No. 153, "Exchanges of Nonmonetary Assets - An Amendment of APB Opinion No. 29." SFAS No. 153 eliminates the exception for nonmonetary exchanges of similar productive assets and replaces it with a general exception for exchanges of nonmonetary assets that do not have commercial substance. SFAS No. 153 specifies that a nonmonetary exchange has commercial substance if the future cash flows of the entity are expected to change significantly as a result of the exchange. SFAS No. 153 is effective for fiscal periods beginning after June 15, 2005. The Company believes this statement will not have a material impact on its results of operations or financial position. On October 22, 2004, the American Jobs Creation Act ("AJCA") was signed into law. Among other provisions, the AJCA creates a new deduction for qualified domestic production activities. Certain activities of the Company, such as its water treatment activity, are considered as qualifying production activities for purposes of determining the deduction for qualified production activities. In December 2004, the FASB issued FSP 109-1, "Application of FASB Statement No. 109, Accounting for Income Taxes, to the Tax Deduction on Qualified Production Activities Provided by the American Jobs Creation Act of 2004." In accordance with FSP 109-1, the Company will treat the deduction for qualified domestic production activities as a reduction of the income tax provision in the period as realized. The Company adopted this statement in the first quarter of 2005 and the effect was to reduce the provision for income taxes by approximately $680 in the first six months of 2005 with approximately $340 of the reduction occurring in the second quarter of 2005. 13

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations AQUA AMERICA, INC. AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued) (In thousands of dollars, except per share amounts) Forward-looking Statements -------------------------- This Management's Discussion and Analysis of Financial Condition and Results of Operations and other sections of this Quarterly Report contain, in addition to historical information, forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements address, among other things: our use of cash; projected capital expenditures; liquidity; possible acquisitions and other growth ventures; the completion of various construction projects; the projected annual value of rate increases; the projected effects of recent accounting pronouncements, as well as information contained elsewhere in this report where statements are preceded by, followed by or include the words "believes," "expects," "anticipates," "plans" or similar expressions. These statements are based on a number of assumptions concerning future events, and are subject to a number of uncertainties and other factors, many of which are outside our control. Actual results may differ materially from such statements for a number of reasons, including the effects of regulation, abnormal weather, changes in capital requirements and funding, acquisitions, and our ability to assimilate acquired operations. In addition to these uncertainties or factors, our future results may be affected by the factors and risk factors set forth in our annual report on Form 10-K for the fiscal year ended December 31, 2004. We undertake no obligation to update or revise forward-looking statements, whether as a result of new information, future events or otherwise. General Information ------------------- Nature of Operations - Aqua America, Inc. ("we" or "us"), a Pennsylvania corporation, is the holding company for regulated utilities providing water or wastewater services to what we estimate to be more than 2.5 million people in Pennsylvania, Ohio, North Carolina, Illinois, Texas, New Jersey, Florida, Indiana, Virginia, Maine, Missouri, New York and South Carolina. Our largest operating subsidiary, Aqua Pennsylvania, Inc., provides water or wastewater services to approximately 1.3 million residents in the suburban areas north and west of the City of Philadelphia and in 21 other counties in Pennsylvania. Our other subsidiaries provide similar services in 12 other states. In addition, we provide water and wastewater service through operating and maintenance contracts with municipal authorities and other parties close to our operating companies' service territories. We are the largest U.S.-based publicly-traded water utility based on number of people served. 14

AQUA AMERICA, INC. AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued) (In thousands of dollars, except per share amounts) Financial Condition ------------------- During the first half of 2005, we had $93,197 of capital expenditures, acquired water and wastewater systems for $2,211, repaid $1,780 of customer advances for construction and repaid debt and made sinking fund contributions and other loan repayments of $47,657. The capital expenditures were related to improvements to treatment plants, new and rehabilitated water mains, tanks, hydrants, and service lines, in addition to well and booster improvements. During the first half of 2005, the proceeds from the issuance of long-term debt, the proceeds from the issuance of common stock, internally generated funds and available working capital were used to fund the cash requirements discussed above and to pay dividends. In February 2005, Aqua America issued unsecured notes of $30,000 at a weighted-average interest rate of 5.086% and the proceeds of this financing were used to refinance existing short-term debt. In May 2005, our Pennsylvania operating subsidiary issued $72,000 tax-exempt bonds secured by a supplement to the trust indenture relating to its First Mortgage Bonds at a weighted-average interest rate of 4.88% due in years ranging from 2036 to 2038. Of the $72,000 in proceeds, $22,000 will be used to retire previously issued tax-exempt bonds of 6.35% in August 2005 and the balance of the proceeds are restricted to fund the costs of certain capital projects in 2005 and 2006. At June 30, 2005, we had short-term lines of credit of $217,000, of which $103,310 was available. Effective with the December 1, 2005 payment, Aqua America increased the quarterly cash dividend on common stock from $0.13 per share to $0.1425 per share. Management believes that internally generated funds along with existing credit facilities and the proceeds from the issuance of long-term debt and common stock will be adequate to meet our financing requirements for the balance of the year and beyond. Results of Operations --------------------- Analysis of First Six Months of 2005 Compared to First Six Months of 2004 ------------------------------------------------------------------------- Revenues for the first six months increased $30,796 or 14.9% primarily due to additional revenues of $17,433 resulting from increased water rates implemented in various operating subsidiaries, and additional water and sewer revenues of $11,876 associated with a larger customer base, primarily resulting from acquisitions, principally the Heater acquisition which closed in June 2004 and the Florida Water acquisition which occurred in June 2004. Operations and maintenance expenses increased by $11,886 or 13.8% primarily due to the additional operating costs associated with acquisitions, principally the Heater and Florida Water acquisitions, increased pension costs, higher purchased water expenses and normal increases in operating costs. 15

AQUA AMERICA, INC. AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued) (In thousands of dollars, except per share amounts) Depreciation expense increased $2,132 or 7.8% reflecting the utility plant placed in service since the second quarter of 2004, including the assets acquired through system acquisitions, offset partially by an adjustment in the second quarter of 2005 resulting from the recent identification of a previously issued rate order that permitted the deferral of $520 of depreciation expense. This depreciation expense was recognized in prior periods. Amortization increased $536 due to the amortization of the costs associated with, and other costs being recovered in, various rate filings. Taxes other than income taxes increased by $1,795 or 12.9% due to the additional taxes associated with acquired operations. Interest expense increased by $2,098 or 9.0% primarily due to additional borrowings to finance the Heater and Florida Water acquisitions, and capital projects, offset partially by decreased interest rates on borrowings due to the refinancing of certain existing debt issues. Allowance for funds used during construction ("AFUDC") decreased by $269 primarily due to investment income of $762 earned in the second quarter of 2005 which reduced both AFUDC and interest expense, and a decrease in the average balance of utility plant construction work in progress, to which AFUDC is applied. These variances were offset partially by additional AFUDC recorded as an adjustment in the second quarter of 2005 of $974 resulting from the recent identification of a previously issued rate order which allowed the continuation of AFUDC on certain capital projects subsequent to being placed into utility service. This AFUDC was not recognized in prior periods. Gain on sale of other assets totaled $505 in the first half of 2005 and $476 in the first half of 2004. The change is due to timing of sales of land and marketable securities. Our effective income tax rate was 39.2% in the first half of 2005 and 39.7% in the first half of 2004. The change was due to the recognition of the American Jobs Creation Act tax deduction for qualified domestic production activities that reduced our tax provision in the first half of 2005 by approximately $680. Net income for the first six months increased by $7,643 or 22.9%, in comparison to the same period in 2004 primarily as a result of the factors described above. On a diluted per share basis, earnings increased $0.06 or 16.7% reflecting the change in net income and a 3.3% increase in the average number of common shares outstanding. The increase in the number of shares outstanding is primarily a result of the additional shares issued in the November 2004 share offering, and the additional shares sold or issued through the dividend reinvestment plan and the employee stock and incentive plan. 16

AQUA AMERICA, INC. AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued) (In thousands of dollars, except per share amounts) Analysis of Second Quarter of 2005 Compared to Second Quarter of 2004 --------------------------------------------------------------------- Revenues for the quarter increased $16,576 or 15.6% primarily due to additional revenues of $9,103 resulting from increased water rates implemented in various operating subsidiaries, and additional water and sewer revenues of $5,589 associated with a larger customer base primarily resulting from acquisitions, principally the Heater acquisition which closed in June 2004 and the Florida Water acquisition which occurred in June 2004. Operations and maintenance expenses increased by $6,408 or 14.4% primarily due to the additional operating costs associated with acquisitions, principally the Heater and Florida Water acquisitions, increased pension costs, higher purchased water expenses and normal increases in operating costs. Depreciation expense increased $1,123 or 8.3% reflecting the utility plant placed in service since the second quarter of 2004, including the assets acquired through system acquisitions, offset partially by an adjustment in the second quarter of 2005 resulting from the recent identification of a previously issued rate order that permitted the deferral of $520 of depreciation expense. This depreciation expense was recognized in prior periods. Amortization decreased $22 or 1.8% due to the amortization of the costs associated with, and other costs being recovered in, various rate filings. Taxes other than income taxes increased by $947 or 13.9% due to the additional taxes associated with acquired operations. Interest expense increased by $1,105 or 9.7% primarily due to additional borrowings to finance the Heater and Florida Water acquisitions, and capital projects, offset partially by decreased interest rates on borrowings due to the refinancing of certain existing debt issues. Allowance for funds used during construction ("AFUDC") decreased by $24 primarily due to investment income of $762 earned in the second quarter of 2005 which reduced both AFUDC and interest expense, and a decrease in the average balance of utility plant construction work in progress, to which AFUDC is applied. These variances were partially offset by additional AFUDC recorded as an adjustment in the second quarter of 2005 of $974 resulting from the recent identification of a previously issued a rate order which allowed the continuation of AFUDC on certain capital projects subsequent to being placed into utility service. This AFUDC was not recognized in prior periods. Gain on sale of other assets totaled $24 in the second quarter of 2005 and $26 in the second quarter of 2004. The change is due to the timing of sales of land. Our effective income tax rate was 39.6% in the second quarter of 2005 and 40.0% in the second quarter of 2004. The change was due to the recognition of the American Jobs Creation Act tax deduction for qualified domestic production activities that reduced our tax provision in the second quarter of 2005 by approximately $340. 17

AQUA AMERICA, INC. AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued) (In thousands of dollars, except per share amounts) Net income for the quarter increased by $4,347 or 24.3%, in comparison to the same period in 2004 primarily as a result of the factors described above. On a diluted per share basis, earnings increased $0.04 or 21.1% reflecting the change in net income and a 3.5% increase in the average number of common shares outstanding. The increase in the number of shares outstanding is primarily a result of the additional shares issued in the November 2004 share offering, and the additional shares sold or issued through the dividend reinvestment plan and the employee stock and incentive plan. Impact of Recent Accounting Pronouncements ------------------------------------------ In May 2005, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 154, "Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20 and FASB Statement No. 3." SFAS No. 154 requires retrospective application to prior periods' financial statements for changes in accounting principle, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 also requires that retrospective application of a change in accounting principle be limited to the direct effects of the change. Indirect effects of a change in accounting principle should be recognized in the period of the accounting change. SFAS No. 154 further requires that a change in depreciation, amortization or depletion method for long-lived, nonfinancial assets be accounted for as a change in accounting estimate effected by a change in accounting principle. Aqua America intends to adopt this standard as required in 2006. In March 2005, the FASB issued FASB Interpretation No. 47, "Accounting for Conditional Asset Retirement Obligations," which clarifies that an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value can be reasonably estimated. The obligation to perform the asset retirement activity is unconditional even though uncertainty exists about the timing and (or) method of settlement. We intend to adopt this standard as required in 2006. We are currently evaluating the provisions of this statement and have not yet determined the effect of adoption on our results of operations or financial position. In December 2004, the FASB issued SFAS No. 123R, "Share-Based Payment," which revises SFAS No. 123, "Accounting for Stock-based Compensation," and supersedes APB No. 25, "Accounting for Stock Issued to Employees." In April 2005, the effective date for this standard was changed to require adoption of the standard at the beginning of the next fiscal year after June 15, 2005. As noted in Note 5 - - Stock-based Compensation, we currently provide pro forma disclosure of our compensation costs associated with the fair value of stock options that have been granted. We currently account for stock-based compensation associated with stock options using the intrinsic method, and accordingly, no compensation costs have been recognized in our consolidated financial statements. SFAS 123R generally requires that we measure the cost of employee services received in exchange for stock-based awards on the grant-date fair value and this cost will be recognized over the period during which an employee provides service in exchange for the award. The fair value of the option grant will be estimated using an option-pricing model. We are currently evaluating this standard to determine the impact on our consolidated financial statements, including the selection of an appropriate option-pricing model as permitted under SFAS No. 123R, and the method by which we will adopt SFAS No. 123R. The impact of adoption of SFAS No. 123R on our earnings cannot be predicted at this time because it will depend on a number of variables including the level of share-based payments granted in the future. However, had we adopted SFAS No. 123R in prior periods, the impact of the standard would not have been materially different from the impact of SFAS 123 as described in the disclosure of pro forma net income and net income per share in Note 5 - Stock-based Compensation. We believe the adoption will have no impact on our overall financial position or cash flow, but will result in the reclassification of related tax benefits from operating cash flow to financing cash flow to the extent these tax benefits exceed the associated compensation cost recognized in the income statement. We are currently evaluating the change in the cash flow reporting and have not yet determined the effect of adoption on our cash flow statement presentation. 18

SFAS No. 151 requires the exclusion of certain costs from inventories and the allocation of fixed production overheads to inventories to be based on the normal capacity of the production facilities. The standard is effective for Aqua America for costs incurred after December 31, 2005. We believe this statement will not have a material impact on our results of operations or financial position. In November 2004, the FASB issued SFAS No. 153, "Exchanges of Nonmonetary Assets - - An Amendment of APB Opinion No. 29." SFAS No. 153 eliminates the exception for nonmonetary exchanges of similar productive assets and replaces it with a general exception for exchanges of nonmonetary assets that do not have commercial substance. SFAS No. 153 specifies that a nonmonetary exchange has commercial substance if the future cash flows of the entity are expected to change significantly as a result of the exchange.

Part II. Other Information Item 1. Legal Proceedings There are no pending legal proceedings to which we or any of our subsidiaries is a party or to which any of their properties is the subject that are material or are expected to have a material effect on our financial position, results of operations or cash flows. 20

BACKGROUND. (a) The Authority proposes to enter into a Financing Agreement (the "Financing Agreement") dated as of May 1, 2005 with the Company, under which the Authority will agree to loan to the Company funds to (i) finance certain capital costs of numerous acquisitions, constructions, modifications, expansions, installations and replacements of water distribution, treatment and related operating systems located in the counties of Berks, Bucks, Chester, Delaware and Montgomery in Pennsylvania (the "2005A Facilities") that are part of the Company's system (the "System") for the distribution of water to its customers, and related financing costs (collectively, the "Construction Project"); and (ii) currently refund (the "Refunding Project") the Authority's Water Facilities Revenue Bonds (Philadelphia Suburban Water Company Project), Series of 1995 (the "1995 Bonds"), which were issued to finance certain capital costs of numerous acquisitions, constructions, modifications, expansions, installations and replacements of water distribution, treatment and related operating systems located in the counties of Bucks, Chester, Delaware and Montgomery in Pennsylvania (the "2005B Facilities" and, together with the 2005A Facilities, the "Facilities") and pay costs of issuance of the 1995 Bonds. To finance the loan under the Financing Agreement, the Authority proposes to issue and sell $49,540,000 aggregate principal amount of Delaware County Industrial Development Authority Water Facilities Revenue Bonds (Aqua Pennsylvania, Inc.

The 2005 Bonds will have such terms as are set forth in Schedule I attached hereto.

The Series A Bonds will be payable out of payments by the Company under the Financing Agreement, including payments under its two First Mortgage Bonds issued with respect to the Series A Bonds in the aggregate principal amount of $49,540,000 (collectively, the "2005A First Mortgage Bond"). The Series B Bonds will be payable out of payments by the Company under the Financing Agreement, including payments under its First Mortgage Bond issued with respect to the Series B Bonds in the principal amount of $21,770,000 (the "2005B First Mortgage Bond" and, together with the 2005A First Mortgage Bond, the "First Mortgage Bonds").

Each First Mortgage Bond will be issued in the same principal amount and will mature on the same date and bear interest at the same rate as the series of 2005 Bonds that it secures.

COMPANY'S COVENANTS.

The Underwriter will reimburse any legal or other expenses reasonably incurred by a party, person or entity indemnifiable under this Section 7 in connection with investigating or defending any such loss, claim, damage, liability or action.

Promptly after a party, person or entity indemnifiable under Section 6 or 7 of this Bond Purchase Agreement (an "Indemnitee") receives notice of the commencement of any audit, investigation or action against such Indemnitee in respect of which indemnity is to be sought by the Indemnitee against the Company or an Underwriter, as the case may be (the "Indemnifying Party"), the Indemnitee will notify the Indemnifying Party in writing of such action, and the Indemnifying Party may assume the defense thereof, including the employment of counsel and the payment of all expenses; but the omission so to notify the Indemnifying Party will not relieve the Indemnifying Party from any liability that it may have to the Indemnitee otherwise than hereunder. The Indemnifying Party shall not be liable for any settlement of any such action effected without its consent, but if settled with the consent of the Indemnifying Party or if there is a final judgment for the plaintiff in any such action, the Indemnifying Party will indemnify and hold harmless the Indemnitee from and against any loss or liability by reason of such settlement or judgment. The indemnity agreements contained in this Bond Purchase Agreement (i) shall include reimbursement for expenses reasonably incurred by an Indemnitee in investigating the claim and in defending it if the Indemnifying Party declines to assume the defense and (ii) shall survive delivery of the 2005 Bonds. Notwithstanding the foregoing, in the event of an investigation or audit by the Internal Revenue Service or the Securities and Exchange Commission or any other state or federal agency, department, or entity with respect to the 2005 Bonds, the Authority shall have the right and duty to undertake its own defense, including the employment of counsel, with full power to litigate, compromise or settle the same on its own behalf, and the Company agrees that it will indemnify and hold the Authority harmless for all costs and expenses, including, but not limited to, attorney fees and expenses and costs, of any such settlement. 10

9. EQUITABLE CONTRIBUTION. If the indemnification provided for in Section 6(b) of this Bond Purchase Agreement is unavailable to the Underwriter (or any controlling person thereof) in respect of any losses, claims, damages or liabilities referred to therein, then the Company shall, in lieu of indemnifying the Underwriter, contribute to the amount paid or payable by the Underwriter as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative benefits received by the Company and the Underwriter, respectively, from the offering of the 2005 Bonds. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then the Company shall contribute to such amount paid or payable by the Underwriter in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Underwriter, respectively, in connection with the statements or omission which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefit received by the Company or the Underwriter shall be deemed to be in the same proportion as the total proceeds from the offering (before deducting issuance costs and expenses other than underwriting fees and commissions) received by the Company, on the one hand, bear to the total underwriting fees and commissions received by the Underwriter, on the other hand. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact related to information supplied by the Company or the Underwriter and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to above in this Section 9. The amount paid or payable by the Underwriter as a result of the losses, claims, damages or liabilities referred to above in this Section 9 shall be deemed to include any reasonable legal or other expenses reasonably incurred by the Underwriter in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the 2005 Bonds underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that the Underwriter has otherwise been required to pay by reason of such untrue or allegedly untrue statement or omission or alleged omission. 11

10. OFFICIAL STATEMENT; PUBLIC OFFERING. (a) In order to enable the Underwriter to comply with Rule 15c2-12: (i) the Company has prepared (or caused to be prepared) the Preliminary Official Statement, which the Company and the Authority (but, in the case of the Authority, only with respect to the information therein under the headings "THE AUTHORITY" and, insofar as they relate to the Authority, "INTRODUCTORY STATEMENT" and "ABSENCE OF MATERIAL LITIGATION") deem final and complete as of its date except for certain "Permitted Omissions" as described in Rule 15c2-12; (ii) the Company shall provide to the Underwriter sufficient copies of the Official Statement in sufficient time to accompany any confirmation that requires payment from any customer and in any event within seven business days after the date of this Bond Purchase Agreement; and (iii) of which the Company has or gains knowledge would render the Official Statement misleading in any material respect in the period from the date of its delivery to the Underwriter by the Company (as that phrase is defined in Rule 15c2-12) then the Company shall promptly give the Underwriter notice thereof. The Authority and the Company hereby authorize the use of the Preliminary Official Statement and the Official Statement by the Underwriter in connection with the offering of the 2005 Bonds. (b) After the Closing, and until the Underwriter has informed the Authority and the Company that the Underwriter has sold all the 2005 Bonds, the Authority and the Company will not adopt or distribute any amendment of or supplement to the Official Statement, except with the prior written consent of the Underwriter; and if any event relating to or affecting the Authority, the Company or the 2005 Bonds shall occur, the result of which shall make it necessary, in the opinion of the Underwriter, to amend or supplement the Official Statement in order to make it not misleading in the light of the circumstances existing at that time, the Company shall forthwith prepare, and the Company and the Authority shall approve for distribution, a reasonable number of copies of an amendment of or supplement to the Official Statement, in form and substance reasonably satisfactory to the Underwriter, so that the Official Statement then will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances existing at that time, not misleading. The Authority shall cooperate with the Company in the issuance and distribution of any such amendment or supplement. (c) Upon Closing, the Underwriter shall promptly provide a Nationally Recognized Municipal Securities Information Repository ("NRMSIR") and the Municipal Securities Rulemaking Board ("MSRB") with a copy of the Official Statement for filing in accordance with Rule 15c2-12, and inform the Authority and the Company in writing as to (i) the date and place of such filing and (ii) the date of the end of the underwriting period. 11.

EXHIBIT A FORM OF APPROVING OPINION OF BALLARD SPAHR ANDREWS & INGERSOLL, LLP Upon delivery of the Bonds, Ballard Spahr Andrews & Ingersoll, LLP, Philadelphia, Pennsylvania, Bond Counsel, will issue its approving opinion in substantially the following form: Re: $49,540,000 aggregate principal amount of Delaware County Industrial Development Authority Water Facilities Revenue Bonds (Aqua Pennsylvania, Inc. Project) Series A of 2005 and $21,770,000 aggregate principal amount of Delaware County Industrial Development Authority Water Facilities Revenue Refunding Bonds (Aqua Pennsylvania, Inc. Project) Series B of 2005 ---------------------------------------------------------------- Ladies and Gentlemen: We have acted as Bond Counsel to the Delaware County Industrial Development Authority (the "Authority") in connection with the issuance and sale of its $49,540,000 aggregate principal amount of Delaware County Industrial Development Authority Water Facilities Revenue Bonds (Aqua Pennsylvania, Inc. Project) Series A of 2005 (the "Series A Bonds") and its $21,770,000 aggregate principal amount of Delaware County Industrial Development Authority Water Facilities Revenue Refunding Bonds (Aqua Pennsylvania, Inc. Project) Series B of 2005 (the "Series B Bonds" and, together with the Series A Bonds, the "Bonds"). The Series A Bonds are being issued by the Authority at the request of Aqua Pennsylvania, Inc., as successor to Philadelphia Suburban Water Company (the "Company"), to finance facilities located in the Pennsylvania Counties of Berks, Bucks, Chester, Delaware and Montgomery (the "2005 Project Facilities") for the furnishing of water which is made available on reasonable demand to members of the general public in portions of the Pennsylvania Counties of Berks, Bucks, Chester, Delaware and Montgomery. The Series B Bonds are being issued by the Authority at the request of the Company to provide for the current refunding of $22,000,000 outstanding principal amount of the Authority's Exempt Facilities Revenue Bonds (Philadelphia Suburban Water Company Project) Series of 1995 (the "1995 Bonds"). The 1995 Bonds were issued at the request of the Company to finance facilities located in the Pennsylvania Counties of Bucks, Chester, Delaware and Montgomery (the "1995 Project Facilities" and, together with the 2005 Project Facilities, the "Project Facilities") for the furnishing of water which is made available on reasonable demand to members of the general public in portions of the Pennsylvania Counties of Bucks, Chester, Delaware and Montgomery. The Bonds are issuable in fully registered form, and are being issued under the Trust Indenture dated as of May 1, 2005 (the "Indenture") between the Authority and Wachovia Bank, National Association, as trustee (the "Trustee"). The Authority and the Company are entering into a Financing Agreement dated as of May 1, 2005 (the "Financing Agreement"), pursuant to which the Authority will lend the proceeds of the Bonds to the Company to (i) finance the 2005 Project Facilities and (ii) currently refund the 1995 Bonds. A-1

In satisfaction of its obligation under the Financing Agreement with respect to the Bonds, the Company, concurrently with the issuance of the Bonds, is delivering to the Trustee (i) its First Mortgage Bond, 5.00% Series, due 2038, and its First Mortgage Bond 5.00% Series, due 2037 (collectively, the "Series A First Mortgage Bonds") in an aggregate principal amount equal to the principal amount of the Series A Bonds and with principal, premium and interest payments corresponding to the principal, premium and interest payments on the Series A Bonds and (ii) its First Mortgage Bond, 5.00% Series, due 2036 (the "Series B First Mortgage Bond" and, together with the Series A Mortgage Bonds, the "First Mortgage Bonds") in the principal amount equal to the principal amount of the Series B Bonds and with principal, premium and interest payments corresponding to the principal, premium and interest payments on the Series B Bonds. The Authority has assigned its interests under the Financing Agreement with respect to the Bonds, including its right to receive the First Mortgage Bonds and the payments thereunder, to the Trustee for the benefit of the holders of the Bonds. The Internal Revenue Code of 1986, as amended (the "Code") establishes certain requirements which must be met on a continuing basis subsequent to the issuance and delivery of the Bonds for interest on the Bonds to be excluded from the gross income of the holders thereof for federal income tax purposes. For the purposes of the opinion set forth below, we have relied on representations of the Authority and the Company with respect to the application of the proceeds of the Bonds and the 1995 Bonds, the nature of the Project Facilities and other matters solely within the knowledge of the Authority and the Company which we have not independently verified, and have assumed continuing compliance with the covenants in the Indenture, the Financing Agreement and the certificates of the Company with respect to the Project Facilities delivered at closing pertaining to the requirements of those sections of the Code which affect the exclusion from gross income of interest on the Bonds for federal income tax purposes. In the event that such representations are determined to be inaccurate or incomplete or the Authority or the Company fails to comply with the aforementioned covenants, interest on the Bonds could become includable in gross income from the date of issuance, regardless of the date on which the event causing such inclusion occurs. In our capacity as Bond Counsel, we have examined such documents, records of the Authority and other instruments as we deemed necessary to enable us to express the opinions set forth below, including original counterparts or certified copies of the Indenture, the Financing Agreement, the First Mortgage Bonds, the other documents listed in the closing memorandum filed with the Trustee and an executed Water Facilities Revenue Bond (Aqua Pennsylvania, Inc. Project) Series A of 2005 and an executed Water Facilities Revenue Refunding Bond (Aqua Pennsylvania, Inc. Project) Series B of 2005, each as authenticated by the Trustee. Based on the foregoing, it is our opinion that: 1. The Authority is a public instrumentality of the Commonwealth of Pennsylvania and a body corporate and politic, organized and existing under Pennsylvania law, with full power and authority to execute and deliver the Financing Agreement and the Indenture, and to issue and sell the Bonds. 2. The Financing Agreement and the Indenture have been duly authorized, executed and delivered by the Authority and constitute legal, valid and binding obligations of the Authority enforceable against the Authority in accordance with their respective terms, subject to state and federal laws and equitable principles affecting the enforcement of creditors' rights. A-2

3. All right, title and interest of the Authority under the Financing Agreement as they relate to the Bonds, including the right to receive the First Mortgage Bonds and the payments thereunder (except for certain rights to indemnification and to payments in respect of administrative expenses of the Authority), have been effectively assigned to the Trustee by the Indenture. 4. The issuance and sale of the Bonds have been duly authorized by the Authority; the Bonds have been duly executed and delivered by the Authority; and, on the assumption that all Bonds have been authenticated by the Trustee, the Bonds are legal, valid and binding obligations of the Authority enforceable against the Authority in accordance with their terms, subject to state and federal laws and equitable principles affecting the enforcement of creditors' rights, and are entitled to the benefit and security of the Indenture. 5. Under existing laws as enacted and construed on the date of initial delivery of the Bonds, interest on the Bonds is excludable from gross income for purposes of federal income tax, assuming the accuracy of the certifications of the Authority and the Company and continuing compliance by the Authority and the Company with the requirements of the Code, except that interest on a Bond is not excludable while the Bond is held by a substantial user of the Project Facilities or a related person as provided in the Code. Interest on the Bonds is a tax preference item that is subject to individual and corporate federal alternative minimum tax. Interest on Bonds held by foreign corporations may be subject to the branch profits tax imposed by the Code. Ownership of the Bonds may result in other federal income tax consequences to certain taxpayers, including, without limitation, financial institutions, property and casualty insurance companies, individual recipients of social security or railroad retirement benefits, certain S corporations and taxpayers who may be deemed to have incurred or continued debt to purchase or carry the Bonds. Bond Counsel expresses no opinion as to these matters. 6. Under the existing laws of the Commonwealth of Pennsylvania as enacted and construed on the date of initial delivery of the Bonds, interest on the Bonds is exempt from Pennsylvania personal income tax and Pennsylvania corporate net income tax, and the Bonds are exempt from personal property taxes in Pennsylvania. We do not express any opinion herein as to the adequacy or accuracy of the Official Statement of the Authority pertaining to the offering of the Bonds. We call your attention to the fact that the Authority's obligation to make payments in respect of the Bonds is limited to moneys received from payments to be made by the Company pursuant to the First Mortgage Bonds and as provided in the Indenture and that the Bonds do not pledge the credit or taxing power of the County of Delaware or the Commonwealth of Pennsylvania or any political subdivision thereof. The Authority has no taxing power. Very truly yours, A-3

Project) Series A of 2005 and $21,770,000 Water Facilities Revenue Refunding Bonds (Aqua Pennsylvania, Inc. Project) Series B of 2005 (collectively, the "Bonds") ---------------------------------------------------------------- Ladies and Gentlemen: We have acted as counsel to the Delaware County Industrial Development Authority ("Authority") in connection with the authorization, execution and issuance by the Authority of the captioned Bonds ("Bonds"). This opinion is being rendered pursuant to Section 11(c)(iii) of the Bond Purchase Agreement, dated May 10, 2005 (the "Bond Purchase Agreement") by and among Sovereign Securities Corporation, LLC ("Underwriter"), Aqua Pennsylvania, Inc. ("Borrower") and the Authority. Capitalized terms used herein and not otherwise defined shall have the meanings ascribed to them in the Bond Purchase Agreement. As the basis for this opinion, we have examined the Pennsylvania Economic Development Financing Law, 73 P.S. ss.ss. 371 et seq., as amended ("Act"); the Resolution of the Authority relating to the Bonds adopted on April 22, 2005 ("Resolution"), and such other documents, certificates and records of the Authority and other instruments and matters of law as we have deemed necessary to enable us to express the opinion set forth below, including, without limitation, original counterparts or certified copies of the Trust Indenture, dated as of May 1, 2005 ("Indenture"), between the Authority and Wachovia Bank, National Association, as trustee ("Trustee"), the Financing Agreement, dated as of May 1, 2005 ("Financing Agreement"), between the Authority and the Borrower), the Escrow Deposit Agreement dated the date hereof ("Escrow Agreement") among the Authority, the Borrower, the Trustee and J.P. Morgan Trust Company, National Association, as escrow agent and the Bond Purchase Agreement. The Indenture, the Loan Agreement, the Escrow Agreement and the Bond Purchase Agreement are collectively referred to herein as the "Authority Documents". C-1

We have assumed and relied upon the truth, completeness, authority and accuracy of all documents, certificates and instruments examined and the authenticity of all signatures thereon. We have also assumed that each of the documents referred to herein are, where appropriate, duly authorized and executed by and valid and legally binding obligations of, and enforceable in accordance with their terms against all parties thereto other than the Authority and that the actions required to be taken or consents required to be obtained by such parties have been taken and obtained. In rendering this opinion, we have also assumed that such parties have acted in full compliance with the terms of all applicable laws, regulations and orders. As to questions of fact material to this opinion, we have relied upon certificates and representations of officers and representatives of the Authority or of other public officials, without independent investigation. We have not made any independent investigation in rendering this opinion other than the examination described above. Our opinion is therefore qualified in all respects by the scope of that examination. Our opinions are specifically limited to the present internal laws of the Commonwealth of Pennsylvania ("Commonwealth") and present federal law and no opinion is expressed as to the effect the laws of any other jurisdiction might have upon the subject matter of the opinions expressed herein under conflict of laws principles or otherwise. Based upon the foregoing, and subject to the limitations, assumptions, qualifications and exceptions set forth herein, we are of the opinion that: 1. The Authority is a body corporate and politic constituting an instrumentality of the Commonwealth and is duly created and existing pursuant to the Act. 2. The Authority has duly authorized the execution and issuance of the Bonds and the execution and delivery of the Authority Documents. The Bonds have been duly and validly executed and delivered by the Authority and the Authority Documents have each been duly and validly executed and delivered by the Authority and the Bonds and each of the Authority Documents are valid and binding agreements of the Authority, enforceable against the Authority in accordance with their respective terms. 3. The execution and the issuance by the Authority of the Bonds, the execution and delivery by the Authority of the Authority Documents and performance by the Authority of the Authority's obligations under the Bonds and the Authority Documents, do not conflict with or constitute on a part of the Authority a violation of, breach of or default under any existing constitutional provision or statute of the Commonwealth applicable to the Authority, or, to our knowledge without having undertaken any independent investigation, any indenture, mortgage, deed of trust, resolution, note agreement or other agreement or instrument to which the Authority is a party or by which the Authority is bound and which is known to us, or, to our knowledge, without having undertaken any independent investigation, any order, rule or regulation of any court, governmental agency or body of the Commonwealth having jurisdiction over the Authority or any of its activities or property. C-2

4. To our knowledge, without having undertaken any independent investigation, there is no action, suit, proceeding, inquiry or investigation, at law or in equity, before or by any court, public board or body, pending or threatened against the Authority, wherein an unfavorable decision, ruling or finding would materially and adversely affect the obligations of the Authority under the Bonds. 5. The Authority has approved the distribution of the Preliminary Official Statement dated April 29, 2005 and the Official Statement dated May 10, 2005 ("Official Statement") by the Underwriter in connection with the offering of the Bonds. 6. The information contained in the Official Statement under the heading "INTRODUCTORY STATEMENT - The Authority" and "THE AUTHORITY" has been reviewed by us and nothing has come to our attention which would lead us to believe that such information contains any untrue statement of a material fact or omits to state a material fact which is required to be stated therein or which is necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading in any material respect. The opinions expressed herein are subject in all respects to the following qualifications: (a) no opinion is rendered as to the availability of equitable remedies including, but not limited to, specific performance and injunctive relief, whether enforceability is considered in a processing in equity or at law; (b) no opinion is rendered as to the effect of bankruptcy, reorganization, insolvency, fraudulent conveyance, moratorium and other similar laws or legal principles affecting creditors' rights or remedies; (c) no opinion is rendered as to the creation, perfection or priority of any lien or security interest; (d) no opinion is rendered with respect to any "blue sky" or other securities laws of the Commonwealth or of other jurisdictions; and (e) no opinion is rendered with regard to any federal income tax law or regulation or any state tax law or regulation of the Commonwealth or of other jurisdictions. No opinion is expressed as to the validity or enforceability of any provisions of the Authority Documents: (a) allowing any person or entity to institute judicial or non-judicial proceedings or to exercise any other rights, without notice to the person or entity against whom enforcement is sought; (b) waiving any right or defense of any person or entity; (c) providing or implying the availability of self-help in any particular event or circumstances; (d) relating to court costs or legal fees which may be properly chargeable or recoverable in any judicial proceedings; (e) relating to indemnification; and (f) relating to confession of judgment. We call your attention to the fact that the Bonds are special and limited obligations of the Authority, payable solely from the payments derived by the Authority under the Financing Agreement. The Bonds are not obligations or liabilities of the Commonwealth or the County of Delaware, Pennsylvania or any other political subdivision thereof nor do the Bonds pledge the credit of the Commonwealth or the County of Delaware, Pennsylvania or any other political subdivision thereof nor do the Bonds pledge the credit of the Authority (other than to the limited extent described above). The Authority has no taxing power. C-3

This opinion is given as of the date hereof. No opinion is expressed as to any matter not set forth in the numbered paragraphs herein. We make no undertaking to supplement this opinion if facts or circumstances hereafter come to our attention or changes in law occur after the date hereof. This opinion is rendered solely in connection with the original delivery and payment for the Bonds on the date hereof, and may not be relied upon for any other purpose. This opinion may not be relied upon by any other person, including any purchaser of the Bonds from the Underwriter or otherwise or for any other purpose, nor may this opinion be distributed, quoted or disclosed to any person, firm or entity without the prior written consent in each instance of a partner of the undersigned firm.

Morgan Trust Company, National Association is trustee (the "Mortgage Trustee"). The Original Mortgage as amended and supplemented is hereinafter called the "Mortgage". Capitalized terms used herein and not otherwise defined shall have the meanings ascribed to such terms in the Purchase Agreement. D-1

We have examined and reviewed, among other things: (a) a copy of the Articles of Incorporation of the Company, as amended and restated and now in effect; (b) a copy of the bylaws of the Company as now in effect; (c) resolutions of the Board of Directors of the Company authorizing the execution and delivery of the Purchase Agreement, the Financing Agreement, the Thirty-Ninth Supplemental Indenture, the First Mortgage Bonds, the Continuing Disclosure Agreement and the Official Statement; (d) the Purchase Agreement; (e) the Financing Agreement dated as of May 1, 2005 (the "Financing Agreement") between the Authority and the Company; (f) the Continuing Disclosure Agreement dated as of May 1, 2005 (the "Continuing Disclosure Agreement") between the Company and Wachovia Bank, National Association, as trustee for the Authority Bonds (the "Trustee"); (g) the Escrow Deposit Agreement dated as of May 1, 2005 (the "Escrow Agreement") among the Authority, the Company, the Trustee and J.P. Morgan Trust Company, National Association, as trustee and escrow agent for the bonds being refunded by the Series B of 2005 Authority Bonds; (h) the Official Statement relating to the Authority Bonds dated May 10, 2005 (the "Official Statement"); (i) the Securities Certificate relating to the issue and sale of the First Mortgage Bonds, filed by the Company with the Pennsylvania Public Utility Commission pursuant to the provisions of Chapter 19 of the Pennsylvania Public Utility Code, and a copy of the Order of the Public Utility Commission registering such Securities Certificate, certified by the Secretary of the Pennsylvania Public Utility Commission; (j) a Subsistence Certificate from the Secretary of the Commonwealth with respect to the Company; (k) executed counterparts of the Original Mortgage and of the Thirty-Ninth Supplemental Indenture supplemental thereto and evidence satisfactory to us of the due recordation thereof in the Counties of Adams, Berks, Bradford, Bucks, Carbon, Chester, Columbia, Cumberland, Delaware, Forest, Juniata, Lackawanna, Lawrence, Luzerne, Mercer, Monroe, Montgomery, Northampton, Northumberland, Pike, Schuylkill, Snyder, Susquehanna, Wayne and Wyoming, Pennsylvania; (l) the documents delivered to the Mortgage Trustee in connection with the authentication of the First Mortgage Bonds pursuant to the provisions of Sections 2(B) and 3 of Article IV of the Original Mortgage; D-2

(m) the First Mortgage Bonds delivered to the Trustee at the Closing held today; (n) the certificates of the Company and other documents delivered to the Mortgage Trustee at the Closing; (o) a certificate of the Company and various bringdown title searches by Commonwealth Land Title Insurance Company in the Counties of Adams, Berks, Bradford, Bucks, Carbon, Chester, Columbia, Cumberland, Delaware, Forest, Juniata, Lackawanna, Lawrence, Luzerne, Mercer, Monroe, Montgomery, Northampton, Northumberland, Pike, Schuylkill, Snyder, Susquehanna, Wayne and Wyoming, Pennsylvania, each dated as of a recent date (collectively, "Title Searches"), as to matters relating to title to real estate and the lien of the Mortgage thereon, on which certificate and searches we are relying for the purposes of this opinion; and (p) various certificates of officers of the Company relating to title to real property and the priority of any lien thereon. In rendering this opinion, we have assumed that all signatures on documents and instruments examined by us are genuine (except signatures of the Company on the Purchase Agreement, the Thirty-Ninth Supplemental Indenture, the Financing Agreement, the First Mortgage Bonds, the Escrow Agreement, and the Continuing Disclosure Agreement (collectively, the "Company Documents") and the Official Statement), the authenticity of all documents submitted to us as originals and the conformity with the original documents of all documents submitted to us as copies. We have also assumed, with your permission, that none of the signatories of the documents and instruments referred to above is an affiliate of the Company within the meaning of 66 Pa.C.S. ss.2101 (1989). As to questions of fact material to the opinions hereinafter expressed, we have relied solely and without investigation upon certificates of public officials, certificates of officers of the Company and the representations of the Company contained in the Company Documents (including the exhibits and schedules to such documents) and the certificates and other documents delivered pursuant thereto. To the extent that the opinions contained herein are given to the best of our knowledge, such knowledge means the actual knowledge of those attorneys within our firm who have provided substantive representation to the Company in connection with this financing, without investigation and inquiry, and does not include matters of which such attorneys could be deemed to have constructive knowledge. In rendering this opinion, we have also assumed that each of the Company Documents has been duly authorized, executed and delivered by each party thereto (other than the Company) and that each of the Company Documents is binding and enforceable against each such party in accordance with its respective terms. Further, as to matters relating to title to real estate and the lien of the Mortgage, we have relied exclusively upon various certificates of officers of the Company and the Title Searches and we have not made, nor undertaken to make, any investigation or inquiry with respect to title to real property or the priority of any lien thereon. D-3

We are generally familiar with the Company's operations as a public utility within the Commonwealth of Pennsylvania (the "Commonwealth"). Based upon the foregoing and such other examination of fact and law as we have deemed necessary for purposes of this opinion, we are of the opinion that: 1. The Company was organized and subsists under the laws of the Commonwealth, with power (corporate and other) to own its properties and conduct its business as described in the Official Statement. 2. The Company has the corporate power and authority to enter into and perform the Purchase Agreement, the Financing Agreement, the First Mortgage Bonds, the Thirty-Ninth Supplemental Indenture, the Escrow Agreement and the Continuing Disclosure Agreement. The execution, delivery and performance by the Company of the Financing Agreement, the Bond Purchase Agreement, the First Mortgage Bonds, the Thirty-Ninth Supplemental Indenture, the Escrow Agreement and the Continuing Disclosure Agreement have been duly authorized by all requisite corporate action. 3. The Purchase Agreement, the Financing Agreement, the Escrow Agreement and the Continuing Disclosure Agreement constitute legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms. 4. Each First Mortgage Bond has been duly authorized, executed, authenticated, issued and delivered and each constitutes a valid and legally binding obligation of the Company entitled to the benefits provided by the Mortgage. 5. The First Mortgage Bonds are not subject to the registration requirements of the 1933 Act. 6. The Mortgage constitutes a direct, valid and enforceable mortgage lien (except as enforceability of such lien may be limited by bankruptcy, insolvency, reorganization or other laws affecting the enforcement of creditors' rights) upon all of the properties and assets of the Company (not heretofore released as provided for in the Mortgage) specifically or generally described or referred to in the Mortgage as being subject to the lien thereof, except for permitted liens under the Mortgage; the Original Mortgage, either separately or as an exhibit to the Thirty-Fifth Supplemental Indenture dated as of January 1, 2002 or the Thirty-Eighth Supplemental Indenture dated as of November 15, 2004, and the Thirty-Ninth Supplemental Indenture have been properly recorded in the Counties of Adams, Berks, Bradford, Bucks, Carbon, Chester, Columbia, Cumberland, Delaware, Forest, Juniata, Lackawanna, Lawrence, Luzerne, Mercer, Monroe, Montgomery, Northampton, Northumberland, Pike, Schuylkill, Snyder, Susquehanna, Wayne and Wyoming in the Commonwealth and such recordations are the only recordations necessary in order to establish, preserve, protect and perfect the lien of the Mortgage on all real estate and fixed property of the Company (excluding easement and other similar rights) described in the Mortgage as subject to the lien thereof. D-4

7. In each of the following cases with such exceptions as are not material and do not interfere with the conduct of the business of the Company, the Company has good and marketable title to all of its real property currently held in fee simple; good and marketable title to all of its other interests in real property (other than to certain rights of way, easements, occupancy rights, riparian and flowage rights, licenses, leaseholds, and real property interests of a similar nature); and good and marketable title to all personal property owned by it; in each case free and clear of all liens, encumbrances and defects except such as may be described in the Official Statement, the lien of the Mortgage, permitted liens under the Mortgage or such as do not materially affect the value of such property and do not interfere with the use made and proposed to be made of such property by the Company; and any real property and buildings held under lease by the Company are held by it under valid, subsisting and enforceable leases with such exceptions as are not material and do not interfere with the use made and proposed to be made of such property and buildings by the Company. 8. The Company is not a holding company, a registered holding company or an affiliate of a registered holding company within the meaning of the Public Utility Company Holding Act of 1935, as amended. 9. The Mortgage and the First Mortgage Bonds conform in all material respects as to legal matters to the descriptions thereof in the Official Statement. Without having undertaken to determine independently the accuracy, completeness and fairness of the statements contained in the Official Statement, nothing has come to our attention in connection with our representation of the Company in respect of the issuance of the First Mortgage Bonds which leads us to believe that the information with respect to the Company contained in the Official Statement (including Appendix A and the information incorporated therein by reference) contains any untrue statement of a material fact or omits to state a material fact which is required to be stated therein or which is necessary to make such information and descriptions, in the light of the circumstances under which they were made, not misleading in any material respect. The foregoing opinions are subject to the following qualifications: (i) The opinions expressed in paragraphs 3 and 4 are subject to the qualifications that the enforceability of the First Mortgage Bonds are subject to (i) applicable bankruptcy, insolvency, reorganization, moratorium, and other similar laws of general application relating to or affecting creditors' rights, (ii) certain provisions of Pennsylvania law affecting the availability of certain remedies, and (iii) the further qualification that the availability of specific performance, injunctive relief or other equitable remedies is subject to the discretion of the court before which any proceeding therefor may be brought. (ii) Our opinions are subject to limitations imposed by general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is considered in proceedings at law or in equity). (iii) We express no opinion as to the enforceability with respect to any provisions purporting to waive the effect of applicable laws and remedies and any provisions releasing any party from, or requiring indemnification for, liability for gross negligence, recklessness or willful misconduct. D-5

(iv) Any requirements in any of the documents specifying that provisions of a document may only be waived in writing may not be enforced to the extent that an oral agreement or an implied agreement by trade practice or course of conduct has been created modifying any provision of such document. (v) We express no opinion as to the applicability to the transactions contemplated by the Company Documents of Section 548 of the Bankruptcy Code or any applicable state law relating to fraudulent transfers and obligations. (vi) Other applicable local, state and federal laws, regulations and ordinances, court decisions and constitutional requirements may limit or render unenforceable certain of the rights or remedies contained in the Company Documents, but in our opinion, none of the same would materially impair the practical realization of the benefits intended to be provided by the Company pursuant to the Company Documents. (vii) Our opinion is limited in all respects to the laws of the Commonwealth in effect as of the date hereof and we express no opinion as to the laws of any other jurisdiction. (viii) This opinion is limited to the matters set forth herein, no opinion may be inferred or implied beyond the matters expressly stated herein, and our statements contained in the opinion portion of this letter must be read in conjunction with the assumptions, limitations, exceptions and qualifications set forth in this letter. (ix) The opinions herein are expressed as of the date hereof only and not as of some future date. We undertake no responsibility to advise you of any change in law or new laws, regulations or judicial decisions in the future. Nor do we assume any obligation to update or supplement this opinion to reflect any facts or circumstances which may hereafter come to our attention. References to "laws," "regulations" and "judicial decisions" herein shall include only officially published laws and regulations of the Commonwealth of Pennsylvania. This opinion is solely for the benefit of each of you and the benefit of any subsequent holder of the First Mortgage Bonds or the Authority Bonds and may not be relied upon by any other person or for any other purpose. Very truly yours, D-6

Project), Series A of 2005 and $21,770,000 Aggregate Principal Amount of Delaware County Industrial Development Authority Water Facilities Revenue Refunding Bonds (Aqua Pennsylvania, Inc. Project), Series B of 2005 (collectively, the "Authority Bonds") --------------------------------------------------------------- Ladies and Gentlemen: I am Senior Vice President-Law and Administration for Aqua Pennsylvania, Inc. (the "Company"). Pursuant to Section 11(c)(iv) of the Bond Purchase Agreement dated May 10, 2005 (the "Purchase Agreement") among the Authority, the Underwriter and the Company (f/k/a Pennsylvania Suburban Water Company, as successor by merger to Philadelphia Suburban Water Company) relating to the Authority Bonds, I have been asked to render an opinion to you regarding certain matters involving the Company. Capitalized terms used herein and not otherwise defined shall have the definitions ascribed to such terms in the Purchase Agreement. In rendering this opinion, I have assumed the following: i. the genuineness of all signatures (other than the signatures of the Company on the Thirty-Ninth Supplemental Mortgage, as hereinafter defined); ii. the authenticity and completeness of all documents submitted to me as originals; iii. the conformity to original documents of all documents submitted to me as copies, and the authenticity of the originals of such copies; iv. the entity executing the Mortgage as trustee is duly organized and validly existing, in good standing under the laws of the jurisdiction of its organization, is properly qualified to do business in all jurisdictions in which the business conducted by it makes such qualification necessary and has all necessary legal and corporate power and authority to enter into and perform its obligations under the Mortgage; D-7

v. the due authorization, execution and delivery of the Mortgage by or on behalf of the party thereto other than the Company; vi. the enforceability against each party thereto (other than the Company) of the Mortgage in accordance with its respective terms; and vii. that the execution, delivery and performance of the Mortgage by the entity other than the Company which is party thereto does not and will not conflict with, result in any breach of, or constitute a default under any order, writ, injunction or decree of any court or governmental authority, or any agreement, indenture or other instrument, to which any such party is a party or by which it or its properties are bound, and that all necessary approvals, consents, permits, registrations, filings or other notices to or grants of authority from any federal or local governmental body necessary for the execution, delivery and performance of the Mortgage by each party thereto (other than the Company) have been duly received or made, with all appeal periods expired and no appeals taken. I am making each of the foregoing assumptions with your permission and with the disclaimer that we make no representation as to the accuracy of such assumptions, although I have no knowledge that any such assumption is untrue. In my opinion: 1. In each of the following cases with such exceptions as are not material and do not materially interfere with the conduct of the business of the Company: (a) the Company has all licenses, franchises, permits, authorizations, rights, approvals, consents and order of all governmental authorities or agencies necessary for the ownership or lease of the properties owned or leased by it and for the operation of the business carried on by it as described in the Official Statement, and all water rights, riparian rights, easements, rights of way and other similar interests and rights described or referred to in the Mortgage necessary for the operation of the business carried on by it as described in the Official Statement; (b) except as otherwise set forth in the Official Statement, all such licenses, franchises, permits, orders, authorizations, rights, approvals and consents are in full force and effect and contain no unduly burdensome provisions; (c) to the best of my knowledge, except as otherwise set forth in the Official Statement, there are no legal or governmental proceedings pending or, to my knowledge, threatened that would result in a material modification, suspension or revocation thereof; and (d) the Company has the legal power to exercise the rights of eminent domain for the purposes of conducting its water utility operations. 2. The issue and sale of the Bonds; the issue and delivery of the First Mortgage Bonds and the compliance by the Company with all of the applicable provisions of the First Mortgage Bonds and the Mortgage; and the execution, delivery and performance by the Company of the Thirty-Ninth Supplemental Mortgage, the Financing Agreement, the Purchase Agreement, the Escrow Agreement and the Continuing Disclosure Agreement will not materially conflict with or result in a material breach of any of the terms or provisions of, or constitute a material default under, or result in the creation or imposition of any material lien, charge or encumbrance (other than the lien of the Mortgage) upon any of the property or assets of the Company pursuant to the terms of, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the property or assets of the Company is subject, nor will such action result in a violation of the provisions of the Articles of Incorporation, as amended, or the Bylaws of the Company or any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any of its property. No consent, approval, authorization, order, registration or qualification of or with any court or any such regulatory authority or other governmental body not already obtained is required for the issue and delivery of the First Mortgage Bonds, the execution, delivery and performance of the Purchase Agreement, the Financing Agreement, the Thirty-Ninth Supplemental Mortgage, the First Mortgage Bonds, the Escrow Agreement and the Continuing Disclosure Agreement, or the consummation of the other transactions contemplated by the Purchase Agreement or the Mortgage. D-8

3. There are no legal or governmental proceedings pending to which the Company is a party or of which any property of the Company is the subject, other than as set forth in the Official Statement and other than litigation incident to the kind of business conducted by the Company, wherein an unfavorable ruling, decision or finding is likely that would have a material adverse effect on the financial position, stockholders' equity or results of operations of the Company. 4. Each of the Indenture of Mortgage dated as of January 1, 1941 (the "Original Mortgage"), between the Company and The Philadelphia Company for Insurance on Lives and Exacting Annuities (now J.P. Morgan Trust Company, National Association, as successor in interest), as trustee (the "Trustee") and the thirty-nine indentures supplemental thereto, including the Thirty-Ninth Supplemental Indenture dated as of May 1, 2005 between the Company and the Trustee (the Original Mortgage as so supplemented and amended, the "Mortgage") was duly authorized, executed and delivered by the Company and the Mortgage constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms (subject to applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws relating to creditors' rights generally from time to time in effect, and subject, as to enforceability, to general principles of equity, regardless of whether such enforceability is considered in a proceeding in equity or at law). The foregoing opinions are subject to the following qualifications: i. The enforceability of the Mortgage, including, without limitation, any non-judicial and self-help remedies and waivers contained therein, may be limited by bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or other similar laws affecting the rights of creditors generally and are subject to limitations imposed by general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is considered in proceedings at law or in equity), public policy and applicable law which may limit the availability of the remedies provided for therein, ii. I express no opinion as to the adequacy of any notice with respect to the disposition of any collateral. I also express no opinion as to the effectiveness or enforceability of provisions relating to waivers of notice or waivers of other rights, severability, prepayment fees or penalties, choice of law, or any provisions which release or limit the Company's liability or relate to cumulative remedies or, to the extent they purport to or would have the effect of compensating the Company in amounts in excess of any actual loss suffered by the Company, provisions relating to the payment of a default rate of interest. D-9
