PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of dollars, except per share amounts) (UNAUDITED) Note 1 Basis of Presentation --------------------- The accompanying consolidated balance sheet and statement of capitalization of Philadelphia Suburban Corporation ("PSC") at September 30, 2003, the consolidated statements of income and comprehensive income for the nine months and quarter ended September 30, 2003 and 2002, and the consolidated statements of cash flow for the nine months ended September 30, 2003 and 2002, are unaudited, but reflect all adjustments, consisting of only normal recurring accruals, which are, in the opinion of management, necessary to present fairly the consolidated financial position, the consolidated results of operations, and the consolidated cash flow for the periods presented. 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 PSC Annual Report on Form 10-K for the year ended December 31, 2002 and the Quarterly Reports on Form 10-Q for the quarters ended June 30, 2003 and March 31, 2003. The results of operations for interim periods may not be indicative of the results that may be expected for the entire year. Note 2 Acquisitions ------------ Pursuant to our strategy to grow through acquisitions, on July 31, 2003, PSC completed its acquisition of four operating water and wastewater subsidiaries of AquaSource, Inc. (a subsidiary of DQE, Inc.), including selected, integrated operating and maintenance contracts and related assets (individually and collectively the acquisition is referred to as "AquaSource") for $195,533 in cash. Pursuant to the purchase agreement, the total amount paid for AquaSource at closing consisted of a purchase price of $190,179 ("purchase price") plus a working capital adjustment of $5,354, both of which are subject to further adjustment upon completion of a closing balance sheet and the finalization of other adjustments that may occur over approximately a six month period. At this time, PSC expects the finalization of adjustments to result in a decrease in the total amount paid for AquaSource. The purchase agreement provides for a minimum purchase price of $174,000. The maximum amount of the working capital adjustment under the purchase agreement is $10,000. The results of AquaSource have been included in our consolidated financial statements beginning August 1, 2003. The acquired operations of AquaSource serve over 130,000 water and wastewater customer accounts in eleven states (including the Connecticut operations which were sold in October 2003). For the fiscal year ended December 31, 2002, the acquired operations had revenues of $69,541 (unaudited). Under the purchase method of accounting, the purchase price is allocated to AquaSource's net tangible and intangible assets based upon their estimated fair values at the date of the acquisition. PSC is in the process of obtaining and reviewing a third-party valuation of the non-regulated net tangible and intangible assets. The purchase price allocation for this acquisition is based on preliminary estimates and valuations and will be refined at a later date with additional information concerning 6

PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of dollars, except per share amounts) (continued) (UNAUDITED) the final purchase price and the final asset and liability valuations. The preliminary purchase price allocation is as follows (unaudited): July 31, 2003 -------- Property, plant and equipment, net $214,187 Current assets 9,783 Other long-term assets 14,204 Assets held for sale, net 4,096 -------- Total assets acquired 242,270 -------- Current liabilities 7,270 Long-term debt 7,170 Other long-term liabilities 32,297 -------- Total liabilities assumed 46,737 -------- Net assets acquired $195,533 ======== The net property, plant and equipment balance includes accumulated depreciation of $91,296. The following supplemental pro forma information is presented to illustrate the effects of the AquaSource acquisition, which was completed on July 31, 2003, on the historical operating results for the three and nine months ended September 30, 2003 and 2002 as if the acquisition had occurred at the beginning of the respective periods (unaudited): Nine Months Ended Three Months Ended September 30, September 30, ---------------------- ---------------------- 2003 2002 2003 2002 -------- -------- -------- -------- Operating revenues $306,416 $291,866 $108,266 $110,549 Net income $ 55,854 $ 52,434 $ 24,261 $ 23,135 Net income per common share: Basic $ 0.77 $ 0.72 $ 0.33 $ 0.32 Diluted $ 0.76 $ 0.71 $ 0.33 $ 0.32 The supplemental information is not necessarily representative of the actual results that may have occurred for these periods or of the results that may occur in the future. This information does not reflect the effects of recent rate increases or cost savings that may result from the acquisition, such as the effects of a reduction in administrative costs. This information is based upon the historical operating results of AquaSource for periods prior to the acquisition date of July 31, 2003 as provided to PSC by AquaSource, Inc. and DQE, Inc. management. In May 2003, PSC announced agreements for the sale of the AquaSource regulated and nonregulated operations located in Connecticut and New York to a New England-based water company for an aggregate purchase price of $5,000 and the assumption of approximately $800 of debt. The sale of the Connecticut regulated operations closed on October 31, 2003. The sale of the New York regulated operations is subject to state regulatory approval. Closing on the sale of the New York operations is expected to occur by early 2004. The combined operations in New York and Connecticut represented approximately 2% of the operations acquired from AquaSource, Inc. 7

PHILADELPHIA SUBURBAN CORPORATION 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 July 2003, PSC issued $135,000 of unsecured notes due 2023 and with an interest rate of 4.87%. In July 2003, an unsecured note of $90,000 was issued by PSC. Interest under this note is based, at the borrower's option, on either a defined base rate or an adjusted London Interbank Offered Rate corresponding to the interest period selected. The proceeds of these financings were used to fund the AquaSource acquisition and to refinance existing debt. The unsecured note of $90,000 was repaid on August 21, 2003 with proceeds from the issuance of common stock. At various times during the first nine months of 2003, our operating subsidiaries issued notes payable in aggregate of $11,480 at various rates ranging from 1% to 5.1% due at various times in 2022, 2023, and 2032. Note 4 Water Rates ----------- During the first nine months of 2003, operating subsidiaries located in Pennsylvania, Illinois, Ohio and Maine were granted rate increases, representing thirteen rate adjustments, intended to increase total revenues by approximately $9,001 on an annual basis. Revenues from the rate increases recorded in the first nine months of 2003 were approximately $5,333. Note 5 Stockholders' Equity -------------------- On August 5, 2003, PSC's Board of Directors declared a 5-for-4 common stock split to be effected in the form of a 25% stock distribution for shareholders of record on November 14, 2003. The new shares will be distributed on December 1, 2003. PSC's par value of $.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. 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 dividend. On August 21, 2003, PSC issued 4,000,000 shares of common stock through a shelf registration, providing proceeds of approximately $90,100, net of expenses. A portion of the net proceeds were used to repay an unsecured note of $90,000. The indebtedness was incurred by PSC in connection with the acquisition of the operations that were purchased from AquaSource, Inc. On May 19, 2003, PSC issued 1,495,000 shares of common stock through a shelf registration, providing proceeds of approximately $33,100, net of expenses. The net proceeds were used to repay short-term debt, including the repayment of $22,000 of indebtedness incurred in connection with our repurchase of 1.2 million shares of our common stock from affiliates of Veolia Environnement, S.A. (formerly Vivendi Environnement, S.A.) in October 2002. 8

PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of dollars, except per share amounts) (continued) (UNAUDITED) PSC reports other comprehensive income in accordance with Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive Income."

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.

PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of dollars, except per share amounts) (continued) (UNAUDITED) Note 7 Stock-Based Compensation ------------------------ PSC 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. Pursuant to the disclosure requirements of SFAS No. 123, "Accounting for Stock-Based Compensation," as amended by SFAS No. 148, pro forma net income available to common stock and earnings per share are presented in the following table as if compensation cost for stock options was determined as of the grant date under the fair value method: Nine Months Ended Three Months Ended September 30, September 30, ---------------------- ------------------- 2003 2002 2003 2002 -------- ------- ------- ------- Net income available to common stock: As reported $ 52,179 $48,508 $23,620 $21,815 Less: pro forma expense related to stock options granted, net of tax effects (1,216) (951) (405) (317) -------- ------- ------- ------- Pro forma $ 50,963 $47,557 $23,215 $21,498 ======== ======= ======= ======= Basic net income per share: As reported $ 0.75 $ 0.71 $ 0.33 $ 0.32 Pro forma 0.73 0.69 0.32 0.31 Diluted net income per share: As reported $ 0.74 $ 0.70 $ 0.33 $ 0.31 Pro forma 0.73 0.69 0.32 0.31 The fair value of options at the date of grant was estimated using the Black-Scholes option-pricing model. Note 8 Recent Accounting Pronouncements -------------------------------- In July 2001, the Financial Accounting Standards Board ("FASB") approved Statement of Financial Accounting Standards ("SFAS") No. 143, "Accounting for Asset Retirement Obligations." SFAS No. 143 requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred. When the liability is initially recognized, the carrying amount of the related long-lived asset is increased by the same amount. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, PSC may settle the obligation for its recorded amount, or an alternative amount, thereby incurring a gain or loss upon settlement. The adoption of this statement as required on January 1, 2003 did not have a material impact on PSC's results of operations or financial position. 10

PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of dollars, except per share amounts) (continued) (UNAUDITED) In April 2002, the FASB approved SFAS No. 145, "Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13, and Technical Corrections." SFAS No. 145, among other things, rescinds SFAS No. 4, which required all gains and losses from the extinguishment of debt to be classified as an extraordinary item and amends SFAS No. 13 to require that certain lease modifications that have economic effects similar to sale-leaseback transactions be accounted for in the same manner as sale-leaseback transactions. PSC adopted this statement in the first quarter of 2003 and it did not have a material impact on PSC's results of operations or financial position. In June 2002, the FASB approved SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities." SFAS No. 146 requires the recognition of costs associated with exit or disposal activities when they are incurred rather than at the date of a commitment to an exit or disposal plan. This statement replaces the previous accounting guidance provided in Emerging Issues Task Force Issue No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)." SFAS No. 146 is effective for exit or disposal activities that are initiated after December 31, 2002. PSC adopted this standard in the first quarter of 2003 and it did not have a material impact on PSC's results of operations or financial position. In November 2002, the FASB issued FASB Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others," an interpretation of SFAS No. 5, 57 and 107 and rescission of SFAS No. 34. This interpretation clarifies the requirements of FASB Statement No. 5, "Accounting for Contingencies" relating to the guarantor's accounting for, and disclosure of, the issuance of certain types of guarantees. The disclosure provisions of the interpretation are effective for financial statements of periods ending after December 15, 2002. The provisions for initial recognition and measurement are effective on a prospective basis for guarantees that are issued or modified after December 31, 2002. PSC adopted the accounting provisions of this standard in the first quarter of 2003 and it did not have a material impact on PSC's results of operations or financial position. In April 2003, the FASB approved SFAS No. 149, "Amendment of Statement No. 133 on Derivative Instruments and Hedging Activities." SFAS No. 149 amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts and for hedging activities. PSC believes the adoption of this standard will have no effect on its results of operations or financial position. As of September 30, 2003, PSC had no derivative instruments or hedging activities. 11

PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (In thousands of dollars, except per share amounts) (continued) (UNAUDITED) In May 2003, the FASB approved SFAS No. 150, "Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity." SFAS No. 150 establishes standards for classifying and measuring as liabilities certain financial instruments with characteristics of both liabilities and equity. The standard is effective for financial instruments entered into or modified after May 31, 2003, and is otherwise effective July 1, 2003. This statement did not have a material impact on PSC's results of operations or financial position. 12

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (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 effects of recent accounting pronouncements; the final purchase price for AquaSource; the completion of the sale of the New York AquaSource operations; the projected annual value of rate increases, the effect of any additional minimum liability that may be recognized in connection with our defined benefit retirement plan, 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, the rate of return on our pension assets, the discount rate used to value pension liabilities, and our ability to assimilate acquired operations. We undertake no obligation to update or revise forward-looking statements, whether as a result of new information, future events or otherwise. General Information ------------------- Philadelphia Suburban Corporation ("we" or "us"), a Pennsylvania corporation, is the holding company for regulated utilities providing water or wastewater services to approximately 2.5 million people in Pennsylvania, Ohio, Illinois, Texas, New Jersey, Indiana, Virginia, Florida, North Carolina, Maine, Missouri, New York, South Carolina and Kentucky. One of our operating subsidiaries provides water or wastewater services to approximately 1.3 million people in the suburban areas north and west of the City of Philadelphia and in 18 other counties in Pennsylvania. 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. 13

PHILADELPHIA SUBURBAN CORPORATION 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 nine months of 2003, we acquired AquaSource for $195,533 in cash, had $105,948 of capital expenditures, repaid $1,306 of customer advances for construction and repaid debt and made sinking fund contributions and other loan repayments of $40,467. The capital expenditures were related to improvements to treatment plants, new and rehabilitated water mains, customer service lines and hydrants, in addition to well and booster improvements. During the first nine months of 2003, the proceeds from the issuance of long-term debt, 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. On May 19, 2003, PSC issued 1,495,000 shares of common stock through a shelf registration, providing proceeds of approximately $33,100, net of expenses. The net proceeds were used to repay short-term debt, including the repayment of $22,000 of indebtedness incurred in connection with our repurchase of 1.2 million shares of our common stock from affiliates of Veolia Environnement, S.A. (formerly Vivendi Environnement, S.A.) in October 2002. In July 2003, PSC issued $135,000 of unsecured notes due 2023 and with an interest rate of 4.87%. Also in July 2003, an unsecured note of $90,000 was issued by PSC. The proceeds of these financings were used to fund the AquaSource acquisition, and to refinance existing debt. At various times during the first nine months of 2003, our operating subsidiaries issued notes payable in aggregate of $11,480 at various rates ranging from 1% to 5.1% due at various times in 2022, 2023, and 2032. On August 21, 2003, PSC issued 4,000,000 shares of common stock through a shelf registration, providing proceeds of approximately $90,100, net of expenses. The net proceeds were used to repay the unsecured note of $90,000 that had been issued in July 2003. The indebtedness had been incurred by PSC in connection with the acquisition of the operations that were purchased from AquaSource, Inc. At September 30, 2003, we had short-term lines of credit of $179,000, of which $69,151 was available. On August 5, 2003, PSC's Board of Directors increased the quarterly cash dividend on common stock from $.14 per share to $.15 per share effective upon the December 1, 2003 payment. On July 31, 2003, we completed the acquisition of four operating water and wastewater subsidiaries of AquaSource, Inc. (a subsidiary of DQE, Inc.), including selected, integrated operating and maintenance contracts and related assets (individually and collectively the acquisition is referred to as "AquaSource") for $195,533 in cash. Pursuant to the purchase agreement, the total amount paid for AquaSource at closing consisted of a purchase price of $190,179 ("purchase price") plus a working capital adjustment of $5,354, both of which are subject to further adjustment upon completion of a closing balance sheet and the finalization of other adjustments that may occur over approximately a six month period. At this time, PSC expects the finalization of adjustments to result in a decrease in the total amount paid for AquaSource. The purchase agreement provides for a minimum purchase price of $174,000. The maximum amount of the working capital adjustment under the purchase agreement is $10,000. The acquired operations of AquaSource serve over 130,000 water and wastewater customer accounts in eleven states (including the Connecticut operations which were sold in October 2003). For the fiscal year ended December 31, 2002, the acquired operations had revenues of $69,451 (unaudited). In May 2003, we announced agreements for the sale of the AquaSource regulated and nonregulated operations located in Connecticut and New York to a New England-based water company for an aggregate purchase price of $5,000 and the 14

PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued) (In thousands of dollars, except per share amounts) assumption of approximately $800 of debt. The sale of the Connecticut regulated operations closed on October 31, 2003. The sale of the New York regulated operations is subject to regulatory approval. Closing on the sale of the New York operations is expected to occur by early 2004. The combined operations in New York and Connecticut represented approximately 2% of the operations acquired from AquaSource, Inc. 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 Nine Months of 2003 Compared to First Nine Months of 2002 --------------------------------------------------------------------------- Revenues for the first nine months increased $25,819 or 10.7% primarily due to increased water rates granted to our Pennsylvania, Ohio, New Jersey and Maine operating subsidiaries, and additional water revenues associated with the larger customer base due to acquisitions, offset by lower water consumption due to unfavorable weather conditions in several of the states where we operate. The above-average rainfall experienced in the summer of 2003 resulted in lower customer water usage as compared to the same period in 2002. The AquaSource acquisition, which was closed on July 31, 2003, provided operating revenues of $11,747 since the date of the acquisition. Operations and maintenance expenses increased by $11,127 or 12.7% primarily due to the additional operating costs associated with acquisitions, primarily from AquaSource, increased postretirement benefits expenses, and higher maintenance expenses, offset in part by reduced bad debt expense. The postretirement benefits expense increase resulted principally from higher pension costs and increased retiree medical costs. The increased maintenance expenses are primarily a result of additional main break repairs resulting from the relatively harsh winter weather that was experienced in 2003. Depreciation expense increased $4,964 or 16.3% reflecting the utility plant placed in service since the third quarter of 2002, including the assets acquired through system acquisitions. Amortization increased $318 due to the AquaSource acquisition and the amortization of the costs associated with, and other costs being recovered in, various rate filings. Taxes other than income taxes increased by $1,151 or 7.8% as a result of the additional taxes associated with the AquaSource acquisition, an increase in state regulatory taxes, and an increase in capital stock tax due to an increase in the base on which the tax is applied. Interest expense increased by $2,728 or 9.0% primarily due to additional borrowings to finance on-going capital projects and acquisitions, offset partially by decreased interest rates on borrowings. Allowance for funds used during construction ("AFUDC") increased by $291 primarily due to an increase in the AFUDC rate as a result of tax-exempt borrowings for our multi-year infrastructure rehabilitation plan and an increase in the average balance of utility plant construction work in progress, associated with the AquaSource acquisition, to which AFUDC is applied. 15

PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued) (In thousands of dollars, except per share amounts) Gain on sale of other assets totaled $4,414 in the first nine months of 2003 and $2,079 in the same period in 2002. The change is due to an increase in the gain on the sale of land realized of $3,382 as compared to the same period in 2002 and a decrease in the gain on sale of marketable securities of $1,047. Our effective income tax rate was 40.0% in the first nine months of 2003 and 38.4% in the first nine months of 2002. The change was due to a decrease in our tax-deductible expenses. Net income available to common stock for the first nine months increased by $3,671 or 7.6%, in comparison to the same period in 2002 primarily as a result of the factors described above. On a diluted per share basis, earnings increased $.04 or 5.7% reflecting the change in net income and a 1.2% 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 through the shelf registration, dividend reinvestment plan, and employee stock purchase plan and equity compensation plan. Analysis of Third Quarter of 2003 Compared to Third Quarter of 2002 ------------------------------------------------------------------- Revenues for the quarter increased $10,235 or 11.1% primarily due to additional water and sewer revenues associated with the larger customer base due to the AquaSource acquisition, and increased water rates granted to our Pennsylvania, Ohio, New Jersey and Maine operating subsidiaries, offset partially by reduced water consumption associated with the wet weather experienced in a significant portion of our service territory during the third quarter of 2003 and the revenues associated with a water system sold in 2002 of $564. The unfavorable weather conditions resulted in lower water consumption by our customers in Pennsylvania, Ohio and New Jersey. Operations and maintenance expenses increased by $5,634 or 18.1% primarily due to the additional operating costs associated with acquisitions, principally the AquaSource acquisition, and increased postretirement benefits expenses, offset partially by reduced water production costs and lower bad debt expenses. The postretirement benefits expense increase resulted principally from higher pension costs. Depreciation expense increased $2,353 or 22.9% reflecting the utility plant placed in service since the third quarter of 2002, including the assets acquired through system acquisitions. Amortization increased $165 due to the AquaSource acquisition and the amortization of the costs associated with, and other costs being recovered in, various rate filings. Taxes other than income taxes increased by $820 or 17.3% due to the additional taxes associated with the AquaSource acquisition and an increase in state taxes. 16

PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued) (In thousands of dollars, except per share amounts) Interest expense increased by $1,136 or 10.7% primarily due to additional borrowings to finance the AquaSource acquisition and capital projects, offset partially by decreased interest rates on borrowings due to refinancing of certain existing debt issues. Allowance for funds used during construction ("AFUDC") increased by $347 primarily due to an increase in the AFUDC rate as a result of tax-exempt borrowings for our multi-year infrastructure rehabilitation plan and an increase in the average balance of utility plant construction work in progress, associated with the AquaSource acquisition, to which AFUDC is applied. Gain on sale of other assets totaled $4,194 in the third quarter of 2003 and $321 in the third quarter of 2002. The change is due to an increase in the gain on the sale of land realized of $3,871 and a slight increase in the gain on sale of marketable securities as compared to the third quarter of 2002. Our effective income tax rate was 40.0% in the third quarter of 2003 and 37.7% in the third quarter of 2002. The change was due to a decrease in our tax-deductible expenses. Net income available to common stock for the quarter increased by $1,805 or 8.3%, in comparison to the same period in 2002 primarily as a result of the factors described above. On a diluted per share basis, earnings increased $.02 or 6.5% reflecting the change in net income and a 4.1% 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 4,000,000 share offering in August 2003. Recent Events ------------- Environmental Regulation - Provision of water and wastewater services is subject to regulation under the federal Safe Drinking Water Act, the Clean Water Act and related state laws, and under state and federal regulations issued under these laws. These laws and regulations establish criteria and standards for drinking water and for discharges to surface waters. In addition, we are subject to federal and state laws and other regulations relating to solid waste disposal, dam safety and other operations. Capital expenditures and operating costs required as a result of water quality standards and environmental requirements have been generally recognized by state public utility commissions as appropriate for inclusion in establishing rates. There are some environmental compliance issues at various water and wastewater facilities associated with the AquaSource acquisition that was completed on July 31, 2003. We estimate that the capital expenditures required to address these AquaSource compliance issues will be approximately $65,000 over the next five years. Various operating subsidiaries that were acquired in the AquaSource acquisition are parties to agreements with regulatory agencies regarding environmental compliance. These agreements are intended to provide the regulators assurance that problems will be addressed, and they generally provide some protection to us from fines, penalties and other actions while corrective measures are being implemented. For the most part, the agreements were negotiated by AquaSource prior to the acquisition being completed, and we have assumed AquaSource's obligations under these agreements. In one case, PSC negotiated a compliance agreement to address conditions that developed prior to 17

PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued) (In thousands of dollars, except per share amounts) closing. Actions remain to be taken to resolve the compliance issues covered by these agreements. We are actively working directly with state environmental officials to implement or amend these agreements as necessary. The regulatory agencies may impose fines and penalties, with respect to existing compliance issues at the AquaSource operations, which are not expected to be material and, to the extent such fines and penalties arise from incidents that occurred prior to our purchase of the AquaSource operations, we may make an indemnity claim for such amounts against DQE, Inc. and AquaSource, Inc. under the purchase agreement. Safe Drinking Water Act - The Safe Drinking Water Act establishes criteria and procedures for the Environmental Protection Agency to develop national quality standards for drinking water. Regulations issued pursuant to the Safe Drinking Water Act and its amendments set standards on the amount of certain microbial and chemical contaminants and radionuclides allowable in drinking water. Current requirements under the Safe Drinking Water Act are not expected to have a material impact on our operations or financial condition as we have already made investments to meet existing water quality standards. We may, in the future, be required to change our method of treating drinking water at certain sources of supply if additional regulations become effective. Issuance by the EPA of a rule regulating radon in tap water has been postponed repeatedly since 1991. Limits for radon would probably become effective 4 or 5 years after issuance of any such rule. We anticipate this rule may establish a radon level that would require treatment at a number of our wells. If the states in which we operate elect not to implement general radon reduction programs (Multi-Media Mitigation), then a lower limit for radon may apply and a larger number of wells would be affected. We anticipate that states will adopt Multi-Media Mitigation programs. The capital costs to comply with the anticipated limit are expected to total approximately $1,000 or less than 1% of our typical annual capital expenditures. The Safe Drinking Water Act provides for the regulation of radionuclides other than radon, such as radium and uranium. In December 2000, the EPA issued a final rule regulating certain radionuclides other than radon. The rule will become effective in December 2003, may require additional testing, and may require additional treatment at a limited number of wells. The cost of compliance is expected to be less than $1,000. The impact of the new rulemaking is not expected to have a material impact on our results from operations or financial condition. In order to eliminate or inactivate microbial organisms, the Surface Water Treatment Rule and the Interim Enhanced Surface Water Treatment Rule were issued by the EPA to improve disinfection or filtration of potable water. The EPA developed the Disinfectants-Disinfection By-products Rule to reduce consumers' exposure to disinfectants and by-products of the disinfection process. In 1998, the EPA issued new rules on disinfection and on surface water treatment. Groundwater and smaller surface water systems have until December 2003 to comply with the rules on disinfection and on surface water treatment. In the future we may be required to install filtration or other treatment for one surface water supply. The cost of this treatment, should it be required, is not expected to exceed $5,000. Certain groundwater systems could be reclassified as being influenced by surface water. This may require additional treatment or the development of replacement sources of supply over time, and the cost for which is not expected to exceed $5,000. 18

PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued) (In thousands of dollars, except per share amounts) In January 2001, the EPA issued a final rule for arsenic that lowers the limit on arsenic in potable water to a more stringent level effective by 2006, with a provision for further time extensions for small systems. Currently, several small well systems slightly exceed the new arsenic levels and may require additional treatment. The cost of maintaining compliance with this new rulemaking is not expected to exceed $1,000 and will not have a material impact on our results from operations or financial condition. In April 2000, the gasoline additive Methyl tert-Butyl Ether ("MtBE") was discovered in a production well in one of our operating subsidiaries at levels exceeding the state drinking water standard. The well was immediately taken out of service and alternate water supplies were obtained. The company responsible for the contamination has reimbursed us for a substantial portion of the expenses incurred to-date. We continue to pursue developing a long-term replacement supply and based on various studies we believe an alternate water system will be needed. We have taken legal action seeking reimbursement for the costs associated with obtaining an alternate long-term water supply, and we expect to recover these costs from the responsible party. Clean Water Act - The Clean Water Act regulates discharges from drinking water and wastewater treatment facilities into lakes, rivers, streams, and groundwater. We operate numerous water and wastewater facilities in a number of states. It is our policy to obtain and maintain all required permits and approvals for the discharge from these water and wastewater facilities, and to comply with all conditions of those permits and other regulatory requirements. A program is in place to monitor facilities for compliance with permitting, monitoring and reporting for wastewater discharges. From time to time, violations may occur which may result in fines. As described previously, various operating subsidiaries that were acquired in the AquaSource acquisition had entered into agreements, prior to the acquisition being completed, to address compliance issues. Based on AquaSource's previous experience with these agreements, penalties or fines that may be imposed under these agreements are not expected to have a material impact on our results of operations or financial condition, and the required costs to comply with the agreements previously cited are expected to be recoverable in rates. Solid Waste Disposal - The handling and disposal of residuals and solids from water and wastewater treatment facilities are governed by state and federal laws and regulations. A program is in place to monitor our facilities for compliance with regulatory requirements, and we do not currently anticipate any major expenditures in connection with the management and disposal of residuals and solids from our water and wastewater facilities in the future. Economic Regulation - The City of Fort Wayne, Indiana is considering the acquisition, by eminent domain or otherwise, of a portion of the utility assets of one of the operating subsidiaries that we acquired in connection with the AquaSource acquisition in July 2003. The system represents approximately 7,500 customers or approximately 1% of our total customer base. We are actively discussing this matter with the City of Fort Wayne officials. We believe that our Indiana operating subsidiary is entitled to fair market value for its assets. 19

PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued) (In thousands of dollars, except per share amounts) Pension Plan - During 2002, the fair market value of our pension plan assets declined due to negative equity market performance and the decrease of the discount rate resulting in an increase in pension liabilities. As a result, we recorded an additional minimum liability of $4,731 on our consolidated balance sheet as of December 31, 2002. The additional minimum liability equaled the excess of the accumulated benefit obligation over the fair value of the plan assets and resulted in the establishment of a regulatory asset, as we anticipate recovery of the future, increased pension expense through customer rates. During the first nine months of 2003, market interest rates have declined and we will likely use a lower discount rate which would have the effect of increasing our pension liabilities. As a result, we will likely be required to recognize an increase to the additional minimum liability at December 31, 2003. The amount of the increased additional minimum liability can not be determined at this time as it is dependent on the asset returns through the fourth quarter of 2003 and the assumed discount rate at the end of the fourth quarter. Name Change - We have announced our intention to change our name to Aqua America, Inc. to reflect our position as the largest U.S.-based publicly-traded water utility. The name change is expected to become effective in mid-January 2004 at which time we will also change our ticker symbol on the New York Stock Exchange and the Philadelphia Stock Exchange from "PSC" to "WTR". Impact of Recent Accounting Pronouncements ------------------------------------------ In July 2001, the Financial Accounting Standards Board ("FASB") approved Statement of Financial Accounting Standards ("SFAS") No. 143, "Accounting for Asset Retirement Obligations." SFAS No. 143 requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred. When the liability is initially recognized, the carrying amount of the related long-lived asset is increased by the same amount. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, we may settle the obligation for its recorded amount, or an alternative amount, thereby incurring a gain or loss upon settlement. The adoption of this statement as required on January 1, 2003 did not have a material impact on our results of operations or financial position. In April 2002, the FASB approved SFAS No. 145, "Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13, and Technical Corrections." SFAS No. 145, among other things, rescinds SFAS No. 4, which required all gains and losses from the extinguishment of debt to be classified as an extraordinary item and amends SFAS No. 13 to require that certain lease modifications that have economic effects similar to sale-leaseback transactions be accounted for in the same manner as sale-leaseback transactions. We adopted this statement in the first quarter of 2003 and it did not have a material impact on our results of operations or financial position. In June 2002, the FASB approved SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities." SFAS No. 146 requires the recognition of costs associated with exit or disposal activities when they are incurred rather than at the date of a commitment to an exit or disposal plan. This statement replaces the previous accounting guidance provided in Emerging Issues Task Force Issue No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring)." SFAS No. 146 is effective for exit or disposal activities that are initiated after December 31, 2002. We adopted this standard in the first quarter of 2003 and it did not have a material impact on our results of operations or financial position. 20

PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued) (In thousands of dollars, except per share amounts) In November 2002, the FASB issued FASB Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others," an interpretation of SFAS No. 5, 57 and 107 and rescission of SFAS No. 34. This interpretation clarifies the requirements of FASB Statement No. 5, "Accounting for Contingencies" relating to the guarantor's accounting for, and disclosure of, the issuance of certain types of guarantees. The disclosure provisions of the interpretation are effective for financial statements of periods ending after December 15, 2002. The provisions for initial recognition and measurement are effective on a prospective basis for guarantees that are issued or modified after December 31, 2002. We adopted the accounting provisions of this standard in the first quarter of 2003 and it did not have a material impact on our results of operations or financial position. In April 2003, the FASB approved SFAS No. 149, "Amendment of Statement No. 133 on Derivative Instruments and Hedging Activities." SFAS No. 149 amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts and for hedging activities. We believe the adoption of this standard will have no effect on our results of operations or financial position. As of September 30, 2003, we had no derivative instruments or hedging activities. In May 2003, the FASB approved SFAS No. 150, "Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity." SFAS No. 150 establishes standards for classifying and measuring as liabilities certain financial instruments with characteristics of both liabilities and equity. The standard is effective for financial instruments entered into or modified after May 31, 2003, and is otherwise effective July 1, 2003. This statement did not have a material impact on our results of operations or financial position. 21

PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES Item 3. Quantitative and Qualitative Disclosures About Market Risk ---------------------------------------------------------- We are subject to market risks in the normal course of business, including changes in interest and equity prices. There have been no significant changes in our exposure to market risks since December 31, 2002. Refer to Item 7A of the Company's Annual Report on Form 10-K for the year ended December 31, 2002 for additional information. Item 4. Controls and Procedures ----------------------- (a) Evaluation of Disclosure Controls and Procedures Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report are functioning effectively to provide reasonable assurance that the information required to be disclosed by us in reports filed under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. A controls system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the controls system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected. (b) Changes in Internal Control over Financial Reporting No change in our internal control over financial reporting occurred during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. 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 expected to have a material effect on our financial position, results of operations or cash flows. 22

SECTION 5. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents and warrants to each Purchaser that: Section 5.1. Organization; Power and Authority. The Company is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, and is duly qualified as a foreign corporation and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Company has the corporate power and authority to own or hold under lease the properties it purports to own or hold under lease, to transact the business it transacts and proposes to transact, to execute and deliver this Agreement and the Notes and to perform the provisions hereof and thereof. Section 5.2. Authorization, Etc. This Agreement and the Notes have been duly authorized by all necessary corporate action on the part of the Company, and this Agreement constitutes, and upon execution and delivery thereof each Note will constitute, a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors' rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). Section 5.3. Disclosure. The Company, through its agent, PNC Capital Markets, Inc., has delivered to each Purchaser a copy of a Private Placement Memorandum, dated June, 2003 (the "Memorandum"), relating to the transactions contemplated hereby. The Memorandum fairly describes, in all material respects, the general nature of the business and principal properties of the Company and its Subsidiaries. This Agreement (excluding the representations of the Purchasers in Section 6), the Memorandum, the documents, certificates or other writings delivered to the Purchasers by or on behalf of the Company in connection with the transactions contemplated hereby and the financial statements listed in Schedule 5.5, taken as a whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made. Since December 31, 2002, there has been no change in the financial condition, operations, business or properties of the Company or any of its Subsidiaries except changes that individually or in the aggregate could not reasonably be expected to have a Material Adverse Effect. There is no fact known to the Company that could reasonably be expected to have a Material Adverse Effect that has not been set forth herein or in the Memorandum or in the other documents, certificates and other writings delivered to each Purchaser by or on behalf of the Company specifically for use in connection with the transactions contemplated hereby. -4-

Section 5.4. Organization and Ownership of Shares of Subsidiaries. (a) Schedule 5.4 contains (except as noted therein) a complete and correct list of the Company's Subsidiaries, showing, as to each Subsidiary, the correct name thereof, the jurisdiction of its organization, and the percentage of shares of each class of its capital stock or similar equity interests outstanding owned by the Company and each other Subsidiary. (b) All of the outstanding shares of capital stock or similar equity interests of each Subsidiary shown in Schedule 5.4 as being owned by the Company and its Subsidiaries have been validly issued, are fully paid and nonassessable and are owned by the Company or another Subsidiary free and clear of any Lien (except as otherwise disclosed in Schedule 5.4). (c) Each Subsidiary identified in Schedule 5.4 is a corporation or other legal entity duly organized, validly existing and in good standing under the laws of its jurisdiction of organization, and is duly qualified as a foreign corporation or other legal entity and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Each such Subsidiary has the corporate or other power and authority to own or hold under lease the properties it purports to own or hold under lease and to transact the business it transacts and proposes to transact. Section 5.5. Financial Statements. The Company has delivered to each Purchaser copies of the financial statements of the Company and its Subsidiaries listed on Schedule 5.5. All of said financial statements (including in each case the related schedules and notes) fairly present in all material respects the consolidated financial position of the Company and its Subsidiaries as of the respective dates specified in such financial statements and the consolidated results of their operations and cash flows for the respective periods so specified and have been prepared in accordance with GAAP consistently applied throughout the periods involved except as set forth in the notes thereto (subject, in the case of any interim financial statements, to normal year-end adjustments). Section 5.6. Compliance with Laws, Other Instruments, Etc. The execution, delivery and performance by the Company of this Agreement and the Notes will not (a) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of the Company or any Subsidiary under, any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, corporate charter or by-laws, or any other Material agreement or instrument to which the Company or any Subsidiary is bound or by which the Company or any Subsidiary or any of their respective properties may be bound or affected, (b) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court, arbitrator or Governmental Authority applicable to the Company or any Subsidiary, or (c) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the Company or any Subsidiary, except for any such default, breach, contravention or violation which would not reasonably be expected to have a Material Adverse Effect. Section 5.7. Governmental Authorizations, Etc. No consent, approval or authorization of, or registration, filing or declaration with, any Governmental Authority is required in connection with the execution, delivery or performance by the Company of this Agreement or the Notes. -5-

Section 5.8. Litigation; Observance of Statutes and Orders. (a) There are no actions, suits or proceedings pending or, to the knowledge of the Company, threatened against or affecting the Company or any Subsidiary or any property of the Company or any Subsidiary in any court or before any arbitrator of any kind or before or by any Governmental Authority that, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect. (b) Neither the Company nor any Subsidiary is in default under any order, judgment, decree or ruling of any court, arbitrator or Governmental Authority or is in violation of any applicable law, ordinance, rule or regulation (including without limitation Environmental Laws) of any Governmental Authority, which default or violation, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect. Section 5.9. Taxes. The Company and its Subsidiaries have filed all income tax returns that are required to have been filed in any jurisdiction, and have paid all taxes shown to be due and payable on such returns and all other taxes and assessments payable by them to the extent such taxes and assessments have become due and payable and before they have become delinquent, except for any taxes and assessments (a) the amount of which is not individually or in the aggregate Material or (b) the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which the Company or a Subsidiary, as the case may be, has established adequate reserves in accordance with GAAP. The charges, accruals and reserves on the books of the Company and its Subsidiaries in respect of federal, state or other taxes for all fiscal periods are adequate. The federal income tax liabilities of the Company and its Subsidiaries have been determined by an audit by the Internal Revenue Service for the fiscal year ended December 31, 1999 and all amounts owing in respect of such audit have been paid. Section 5.10. Title to Property; Leases. The Company and its Subsidiaries have good and sufficient title to their respective Material properties, including all such properties reflected in the most recent audited balance sheet referred to in Section 5.5 or purported to have been acquired by the Company or any Subsidiary after said date (except as sold or otherwise disposed of in the ordinary course of business), in each case free and clear of Liens prohibited by this Agreement, except for those defects in title and Liens that, individually or in the aggregate, would not have a Material Adverse Effect. All Material leases are valid and subsisting and are in full force and effect in all material respects. Section 5.11. Licenses, Permits, Etc. Except as disclosed in Schedule 5.11, the Company and its Subsidiaries own or possess all licenses, permits, franchises, certificates of conveyance and necessity, authorizations, patents, copyrights, service marks, trademarks and trade names, or rights thereto, that are Material, without known conflict with the rights of others except for those conflicts, that, individually or in the aggregate, would not have a Material Adverse Effect. Section 5.12. Compliance with ERISA. (a) The Company and each ERISA Affiliate have operated and administered each Plan in compliance with all applicable laws except for such instances of noncompliance as have not resulted in and could not reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in Section 3 of ERISA), and no event, transaction or condition has occurred or exists that would reasonably be expected to result in the incurrence of any such liability by the Company or any ERISA Affiliate, or in the imposition of any Lien on any of the rights, properties or assets of the Company or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or 412 of the Code, other than such liabilities or Liens as would not be individually or in the aggregate Material. -6-

(b) The present value of the accrued benefit liabilities under each of the Plans (other than Multiemployer Plans), determined as of the end of such Plan's most recently ended plan year on the basis of the actuarial assumptions specified for funding purposes in such Plan's most recent actuarial valuation report, did not exceed the aggregate current value of the assets of such Plan allocable to such benefit liabilities. The term "benefit liabilities" has the meaning specified in section 4001 of ERISA and the terms "current value" and "present value" have the meaning specified in Section 3 of ERISA. (c) The Company and its ERISA Affiliates have not incurred any withdrawal liabilities (and are not subject to contingent withdrawal liabilities) under Section 4201 or 4204 of ERISA in respect of Multiemployer Plans that individually or in the aggregate are Material. (d) The expected post-retirement benefit obligation (determined as of the last day of the Company's most recently ended fiscal year in accordance with Financial Accounting Standards Board Statement No. 106, without regard to liabilities attributable to continuation coverage mandated by section 4980B of the Code) of the Company and its Subsidiaries is not Material. (e) The execution and delivery of this Agreement and the issuance and sale of the Notes hereunder will not involve any transaction that is subject to the prohibitions of Section 406 of ERISA or in connection with which a tax could be imposed pursuant to Section 4975(c)(1)(A)-(D) of the Code. The representation by the Company in the first sentence of this Section 5.12(e) is made in reliance upon and subject to the accuracy of each Purchaser's representation in Section 6.2 as to the sources of the funds to be used to pay the purchase price of the Notes to be purchased by such Purchaser. Section 5.13. Private Offering by the Company. Neither the Company nor anyone acting on the Company's behalf has offered the Notes or any similar securities for sale to, or solicited any offer to buy any of the same from, or otherwise approached or negotiated in respect thereof with, any Person other than the Purchasers and not more than 24 other Institutional Investors, each of which has been offered the Notes in connection with a private sale for investment. Neither the Company nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Notes to the registration requirements of Section 5 of the Securities Act. -7-

Section 5.14. Use of Proceeds; Margin Regulations. The Company will apply the proceeds of the sale of the Notes for general corporate purposes of the Company and its Subsidiaries (including the repayment of Debt of the Company and its Subsidiaries) and to finance the acquisition of certain subsidiaries of AquaSource, Inc. No part of the proceeds from the sale of the Notes hereunder will be used, directly or indirectly, for the purpose of buying or carrying any margin stock within the meaning of Regulation U of the Board of Governors of the Federal Reserve System (12 CFR 221), or for the purpose of buying or carrying or trading in any securities under such circumstances as to involve the Company in a violation of Regulation X of said Board (12 CFR 224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock does not constitute more than 2% of the value of the consolidated assets of the Company and its Subsidiaries and the Company does not have any present intention that margin stock will constitute more than 2% of the value of such assets. As used in this Section, the terms "margin stock" and "purpose of buying or carrying" shall have the meanings assigned to them in said Regulation U. Section 5.15. Existing Debts. Except as described therein, Schedule 5.15 sets forth a complete and correct list of all outstanding Debt of the Company and its Subsidiaries as of June 30, 2003, since which date there has been no Material change in the amounts, interest rates, sinking funds, installment payments or maturities of the Debt of the Company or its Subsidiaries. Neither the Company nor any Subsidiary is in default and no waiver of default is currently in effect, in the payment of any principal or interest on any Debt of the Company or such Subsidiary, and no event or condition exists with respect to any Debt of the Company or any Subsidiary, the outstanding principal amount of which exceeds $5,000,000, that would permit (or that with notice or the lapse of time, or both, would permit) one or more Persons to cause such Debt to become due and payable before its stated maturity or before its regularly scheduled dates of payment. Section 5.16. Foreign Assets Control Regulations, Etc. Neither the sale of the Notes by the Company hereunder nor its use of the proceeds thereof will violate the Trading with the Enemy Act, as amended, or any of the foreign assets control regulations of the United States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or executive order relating thereto or is in violation of any federal statute or Presidential Executive Order, including without limitation Executive Order 13224 66 Fed. Reg. 49079 (September 25, 2001) (Blocking Property and Prohibiting Transactions with Persons who Commit, Threaten to Commit or Support Terrorism). Section 5.17. Status under Certain Statutes. Neither the Company nor any Subsidiary is an "investment company" registered or required to be registered under the Investment Company Act of 1940, as amended, or is subject to regulation under the Public Utility Holding Company Act of 1935, as amended, the ICC Termination Act of 1995, as amended, or the Federal Power Act, as amended. Section 5.18. Environmental Matters. Neither the Company nor any Subsidiary has knowledge of any claim or has received any notice of any claim, and no proceeding has been instituted raising any claim against the Company or any of its Subsidiaries or any of their respective real properties now or formerly owned, leased or operated by any of them, or other assets, alleging damage to the environment or any violation of any Environmental Laws, except, in each case, such as could not reasonably be expected to result in a Material Adverse Effect. Except as otherwise disclosed to each Purchaser in writing: -8-

(a) neither the Company nor any Subsidiary has knowledge of any facts which would give rise to any claim, public or private, for violation of Environmental Laws or damage to the environment emanating from, occurring on or in any way related to real properties or to other assets now or formerly owned, leased or operated by any of them or their use, except, in each case, such as could not reasonably be expected to result in a Material Adverse Effect; (b) neither the Company nor any of its Subsidiaries has stored any Hazardous Materials on real properties now or formerly owned, leased or operated by any of them or has disposed of any Hazardous Materials in each case in a manner contrary to any Environmental Laws and in any manner that could reasonably be expected to result in a Material Adverse Effect; and (c) all buildings on all real properties now owned, leased or operated by the Company or any of its Subsidiaries are in compliance with applicable Environmental Laws, except where failure to comply could not reasonably be expected to result in a Material Adverse Effect. SECTION 6. REPRESENTATIONS OF THE PURCHASER. Section 6.1. Purchase for Investment. Each Purchaser represents that it is purchasing the Notes for its own account or for one or more separate accounts maintained by it or for the account of one or more pension or trust funds and not with a view to the distribution thereof, provided that the disposition of such Purchaser's or such pension or trust funds' property shall at all times be within such Purchaser's or such pension or trust funds' control. Each Purchaser understands that the Notes have not been registered under the Securities Act and may be resold only if registered pursuant to the provisions of the Securities Act or if an exemption from registration is available, except under circumstances where neither such registration nor such an exemption is required by law, and that the Company is not required to register the Notes.

The Company will give each holder of Notes written notice of each optional prepayment under this Section 8.2 not less than 30 days and not more than 60 days prior to the date fixed for such prepayment.

Any such offer shall provide each holder with sufficient information to enable it to make an informed decision with respect to such offer, and shall remain open for at least 15 Business Days. If the holders of more than 10% of the principal amount of the Notes then outstanding accept such offer, the Company shall promptly notify the remaining holders of such fact and the expiration date for the acceptance by holders of Notes of such offer shall be extended by the number of days necessary to give each such remaining holder at least 10 Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes. Section 8.6. Make-Whole Amounts. The term "Make-Whole Amount" means with respect to a Note an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings: "Called Principal" means, with respect to a Note, the principal of such Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. "Discounted Value" means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal. "Reinvestment Yield" means, with respect to the Called Principal of any Note, 0.50% plus the yield to maturity implied by (i) the yields reported, as of 10:00 A.M. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as "PX-1" on the Bloomberg Financial Market Screen (or such other display as may replace "PX-1" on the Bloomberg Financial Market Screen) for actively traded U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable, the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (519) (or any comparable successor publication) for actively traded U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. Such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond-equivalent yields in accordance with accepted financial practice and (b) interpolating linearly on a straight line basis between (1) the actively traded U.S. Treasury security with the maturity closest to and greater than the Remaining Average Life and (2) the actively traded U.S. Treasury security with the maturity closest to and less than the Remaining Average Life. -16-

"Remaining Average Life" means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment. "Remaining Scheduled Payments" means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 or 12.1. "Settlement Date" means, with respect to the Called Principal of any Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. Section 8.7. Change in Control. (a) Notice of Change in Control or Control Event. The Company will, within five Business Days after any Responsible Officer has knowledge of the occurrence of any Change in Control or Control Event, give written notice of such Change in Control or Control Event to each holder of Notes unless notice in respect of such Change in Control (or the Change in Control contemplated by such Control Event) shall have been given pursuant to subparagraph (b) of this Section 8.7. If a Change in Control has occurred, such notice shall contain and constitute an offer to prepay Notes as described in subparagraph (c) of this Section 8.7 and shall be accompanied by the certificate described in subparagraph (g) of this Section 8.7. (b) Condition to Company Action. The Company will not take any action that consummates or finalizes a Change in Control unless (i) at least 20 days prior to such action it shall have given to each holder of Notes written notice containing and constituting an offer to prepay Notes as described in subparagraph (c) of this Section 8.7, accompanied by the certificate described in subparagraph (g) of this Section 8.7, and (ii) contemporaneously with such action, it prepays all Notes required to be prepaid in accordance with this Section 8.7. -17-

(c) Offer to Prepay Notes. The offer to prepay Notes contemplated by subparagraphs (a) and (b) of this Section 8.7 shall be an offer to prepay, in accordance with and subject to this Section 8.7, all, but not less than all, the Notes held by each holder (in this case only, "holder" in respect of any Note registered in the name of a nominee for a disclosed beneficial owner shall mean such beneficial owner) on a date specified in such offer (the "Proposed Prepayment Date"). If such Proposed Prepayment Date is in connection with an offer contemplated by subparagraph (a) of this Section 8.7, such date shall be not less than 20 days and not more than 60 days after the date of such offer (if the Proposed Prepayment Date shall not be specified in such offer, the Proposed Prepayment Date shall be the 30th day after the date of such offer). (d) Acceptance/Rejection. A holder of Notes may accept the offer to prepay made pursuant to this Section 8.7 by causing a notice of such acceptance to be delivered to the Company at least 5 days prior to the Proposed Prepayment Date. A failure by a holder of Notes to respond to an offer to prepay made pursuant to this Section 8.7 shall be deemed to constitute acceptance of such offer by such holder. (e) Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.7 shall be at 100% of the principal amount of such Notes together with interest on such Notes accrued to the date of prepayment. On the Business Day preceding the date of prepayment, the Company shall deliver to each holder of Notes being prepaid a statement showing the amount due in connection with such prepayment and setting forth the details of the computation of such amount. The prepayment shall be made on the Proposed Prepayment Date except as provided in subparagraph (f) of this Section 8.7. (f) Deferral Pending Change in Control. The obligation of the Company to prepay Notes pursuant to the offers required by subparagraph (c) and accepted in accordance with subparagraph (d) of this Section 8.7 is subject to the occurrence of the Change in Control in respect of which such offers and acceptances shall have been made. In the event that such Change in Control does not occur on the Proposed Prepayment Date in respect thereof, the prepayment shall be deferred until and shall be made on the date on which such Change in Control occurs. The Company shall keep each holder of Notes reasonably and timely informed of (i) any such deferral of the date of prepayment, (ii) the date on which such Change in Control and the prepayment are expected to occur, and (iii) any determination by the Company that efforts to effect such Change in Control have ceased or been abandoned (in which case the offers and acceptances made pursuant to this Section 8.7 in respect of such Change in Control shall be deemed rescinded).

Each offer to prepay the Notes pursuant to this Section 8.7 shall be accompanied by a certificate, executed by a Senior Financial Officer of the Company and dated the date of such offer, specifying: (i) the Proposed Prepayment Date; (ii) that such offer is made pursuant to this Section 8.7; (iii) the principal amount of each Note offered to be prepaid; (iv) the interest that would be due on each Note offered to be prepaid, accrued to the Proposed Prepayment Date; (v) that the conditions of this Section 8.7 have been fulfilled; (vi) in reasonable detail, the nature and date of the Change in Control; and (vii) that the failure to respond to such offer of prepayment shall constitute acceptance of such offer. -18-

However, any such information relating to such U.S. federal tax treatment and U.S. federal tax structure is required to be kept confidential to the extent necessary to comply with any applicable securities laws.

Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be entitled to the benefits of this Section 20 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note of information required to be delivered to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying the provisions of this Section 20. -36-

SECTION 21. SUBSTITUTION OF PURCHASER.

Upon receipt of such notice, wherever the word "Purchaser" is used in this Agreement (other than in this Section 21), such word shall be deemed to refer to such Affiliate in lieu of such Purchaser. In the event that such Affiliate is so substituted as a purchaser hereunder and such Affiliate thereafter transfers to such Purchaser all of the Notes then held by such Affiliate, upon receipt by the Company of notice of such transfer, wherever the word "Purchaser" is used in this Agreement (other than in this Section 21), such word shall no longer be deemed to refer to such Affiliate, but shall refer to such Purchaser, and such Purchaser shall have all the rights of an original holder of the Notes under this Agreement. SECTION 22. MISCELLANEOUS. Section 22.1. Successors and Assigns. All covenants and other agreements contained in this Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not.

Anything in this Agreement or the Notes to the contrary notwithstanding, any payment of principal of or Make-Whole Amount or interest on any Note that is due on a date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day. Section 22.3. Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction. Section 22.4. Construction. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person. Section 22.5. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto. -37-

The Company has the full corporate power and the corporate authority to conduct the activities in which it is now engaged and is duly licensed or qualified and is in good standing as a foreign corporation in each jurisdiction in which the character of the properties owned or leased by it or the nature of the business transacted by it makes such licensing or qualification necessary except in jurisdictions where the failure to be so qualified or licensed would not have a material adverse effect on the business of the Company. 2. Each Subsidiary is a corporation duly incorporated, validly existing and in good standing under the laws of its jurisdiction of incorporation, and is duly licensed or qualified and is in good standing and has valid and subsisting franchises and certificates of conveyance and necessity in each jurisdiction in which the character of the properties owned or leased by it or the nature of the business transacted by it makes such licensing or qualification or the possession of such franchises and certificates of conveyance and necessity necessary except in jurisdictions where the failure to be so qualified or licensed to possess such would not have a material adverse effect on the business of the Subsidiaries and the Company taken as a whole. Except as set forth in Schedule 5.4 to the Note Purchase Agreement, all of the issued and outstanding shares of capital stock of each such Subsidiary have been duly issued, are fully paid and non-assessable and are owned by the Company, by one or more Subsidiaries, or by the Company and one or more Subsidiaries. 3.

There are no actions, suits or proceedings pending or, to the knowledge of such counsel after due inquiry, threatened against or affecting the Company or any Subsidiary in any court or before any governmental authority or arbitration board or tribunal which are both likely to be, adversely determined, and if so determined would have a materially adverse effect on the properties, business, prospects, profits or condition, (financial or otherwise) of the Company and its Subsidiaries taken as a whole or the ability of the Company to perform its obligations under the Note Purchase Agreement and the Notes or on the legality, validity or enforceability of the Company's obligations under the Note Purchase Agreement or the Notes. To the knowledge of such counsel, neither the Company nor any Subsidiary is in default with respect to any order of any court or governmental authority, or arbitration board or tribunal which default would have a materially adverse effect on the Subsidiaries and the Company taken as a whole.

If and to the extent that such Bank shall not have made such Loan available to the Agent, such Bank and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Agent at (i) in the case of the Borrower, the interest rate applicable at the time to the Loans and (ii) in the case of such Bank, the Federal Funds Effective Rate. If such Bank shall repay to the Agent such corresponding amount, such amount shall constitute such Bank's Loan for purposes of this Agreement. (b) All conversions and continuations of Loans hereunder and all selections of Interest Periods hereunder shall be in such amounts and be made pursuant to such elections so that, after giving effect thereto, (A) the aggregate principal amount of the portion of the Loans comprising each Tranche of Eurodollar Loans shall be equal to $500,000 or a whole multiple of $100,000 in excess thereof and (B) the Borrower shall not have outstanding at any one time more than in the aggregate five (5) separate Tranches of Eurodollar Loans. 2.3 Fees. (a) The Borrower agrees to pay to the Agent for its and each Bank's account, as applicable, administrative, closing and other fees at the times and in the amounts set forth in the Fee Letter (collectively, the "Fees"). (b) All fees payable pursuant to this Section 2.3 shall be paid on the dates due, in immediately available funds, to the Agent. Once paid, none of such fees shall be refundable under any circumstances. 2.4 Notes; Repayment of Loans. The Loan made by each Bank shall be evidenced by a single Note duly executed on behalf of the Borrower, dated the Closing Date, in substantially the form attached hereto as Exhibit A with the blanks appropriately filled, payable to such Bank in a principal amount equal to the Loan made by such Bank. Each Note shall bear interest from the date thereof on the outstanding principal balance thereof as set forth in Section 2.5. Each Bank shall, and is hereby authorized by the Borrower to, endorse on the schedule attached to the relevant Note held by such Bank (or on a continuation of such schedule attached to each such Note and made a part thereof), or otherwise to record in such Bank's internal records, an appropriate notation evidencing the date and amount of the Loan of such Bank, each payment or prepayment of principal of the Loan, and the other information provided for on such schedule; provided, however, that the failure of any Bank to make such a notation or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loan made by such Bank in accordance with the terms of the relevant Note. The outstanding principal balance of each Loan, as evidenced by the relevant Note, shall be payable on the Maturity Date and is subject to optional and mandatory prepayment as provided in Section 2.7. 15

2.5 Interest on Loans. (a) Subject to the provisions of Section 2.6, each Base Rate Loan shall bear interest (computed on the basis of the actual number of days elapsed over a year of 365 or 366 days, as the case may be) at a rate per annum equal to the Base Rate. (b) Subject to the provisions of Section 2.6, each Eurodollar Loan shall bear interest (computed on the basis of the actual number of days elapsed over a year of 360 days) at a rate per annum equal to the Eurodollar Rate for the Interest Period in effect for such Eurodollar Loan plus the Applicable Margin. (c) Interest on each Loan shall be payable on each Interest Payment Date applicable to such Loan; provided that, interest accruing on overdue amounts pursuant to Section 2.6 shall be payable on demand as provided in the Notes. The Eurodollar Rate and the Base Rate shall be determined by the Agent, and such determination shall be conclusive absent error. 2.6 Default Rate; Additional Interest; Alternate Rate of Interest. (a) To the extent not contrary to any Requirement of Law, upon the occurrence and during the continuation of an Event of Default, any principal, past due interest, fee or other amount outstanding hereunder shall, at the option of the Required Banks, bear interest for each day thereafter until paid in full (after as well as before judgment) at a rate per annum which shall be equal to two percent (2%) above the Base Rate (but in no event shall any such rate exceed the maximum rate permitted by any Requirement of Law). The Borrower acknowledges that such increased interest rate reflects, among other things, the fact that such loans or other amounts have become a substantially greater risk given their default status and that the Banks are entitled to additional compensation for such risk. (b) In the event, and on each occasion, that on the day two Business Days prior to the commencement of any Interest Period for a Eurodollar Loan, the Agent shall have determined (which determination absent manifest error shall be conclusive and binding upon the Borrower) that dollar deposits in the principal amount of such Eurodollar Loan are not generally available in the London Interbank Market, or that the rate at which such dollar deposits are being offered will not adequately and fairly reflect the cost to the Banks of making or maintaining the principal amount of such Eurodollar Loan during such Interest Period, or that reasonable means do not exist for ascertaining the Eurodollar Rate, the Agent shall, as soon as practicable thereafter, give written, telegraphic or telephonic notice of such determination to the Borrower and the Banks, and any request by the Borrower for a Eurodollar Loan or for conversion to or maintenance of a Eurodollar Loan pursuant to the terms of this Agreement shall be deemed a request for a Base Rate Loan. After such notice shall have been given and until the circumstances giving rise to such notice no longer exist, each request for a Eurodollar Loan shall be deemed to be a request for a Base Rate Loan. Each determination by the Agent hereunder shall be conclusive absent manifest error. 16

2.7 Optional and Mandatory Prepayments of Loans. (a) The Borrower shall have the right at any time and from time to time to prepay the Loans, in whole or in part, without premium or penalty (but in any event subject to Section 2.11), upon prior written, telecopy or telephonic notice to the Agent given no later than 11:00 a.m., Philadelphia time, one Business Day before any proposed prepayment; provided, however, that each such partial prepayment of Loans shall be in the principal amount of at least $500,000 or in multiples of $100,000 in excess thereof. (b) The Borrower shall pay to the Agent monthly installments, each in the amount of $750,000, on the last day of each month beginning February 28, 2004, which shall be applied by the Agent to the prepayment of the Loans then outstanding, without premium or penalty (but in any event subject to Section 2.11). (c) Promptly upon receipt by the Borrower of any Net Proceeds from any Equity Issuance by the Borrower or the incurrence after the date hereof by the Borrower of indebtedness for borrowed money (other than under operating lines of credit), the Borrower shall pay to the Agent 100% of such Net Proceeds. Such payments shall be applied by the Agent to the prepayment of the Loans then outstanding, without premium or penalty (but in any event subject to Section 2.11) with such payments being applied to reduce the installments of principal in inverse order of maturity. The Borrower shall give the Agent no later than 11:00 a.m., Philadelphia time, one Business Day's prior written, telecopy or telephonic notice of each prepayment pursuant to this clause (b) setting forth the date and expected amount thereof. All prepayments of the Loans under this clause (b) shall be applied to Base Rate Loans then outstanding and the balance, if any, shall be applied to Eurodollar Loans then outstanding, with payments applied to Eurodollar Loans being applied in order of next maturing Interest Periods. (d) Promptly following demand of the Agent at any time on or after the occurrence of a Change of Control, the Borrower shall prepay the Loans in full without premium or penalty (but in any event subject to Section 2.11). (e) Each required notice of prepayment shall specify the prepayment date and the principal amount of the Loans to be prepaid, shall be irrevocable and shall commit the Borrower to prepay such Loans (or portion thereof) by the amount stated therein. All prepayments under this Section on other than Base Rate Loans shall be accompanied by accrued interest on the principal amount being prepaid to the date of prepayment. No prepayments of the Loans, whether optional or mandatory, may be reborrowed by the Borrower. 2.8 Illegality. Notwithstanding any other provision herein, if any change in any Requirement of Law or in the interpretation or application thereof shall make it unlawful for any Bank to make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such Bank hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and convert Base Rate Loans to Eurodollar Loans shall forthwith be cancelled and (b) the portion of such Bank's Loan then outstanding as Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans on the respective last days of the then current Interest Periods with respect to such Loan or within such earlier period as required by law. If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, the Borrower shall pay to such Bank such amounts, if any, as may be required pursuant to Section 2.11. 17

2.9 Requirements of Law. (a) In the event that any change in any Requirement of Law or in the interpretation, or application thereof or compliance by any Bank with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof: (i) shall subject any Bank to any tax of any kind whatsoever with respect to this Agreement, any Note or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Bank in respect thereof (except for taxes covered by Section 2.12 and changes in the rate of tax on the overall net income, gross receipts or revenue of such Bank); (ii) shall impose, modify or hold applicable any reserve, special deposit or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Bank which is not otherwise included in the determination of the interest rate on such Eurodollar Loan hereunder; or (iii) shall impose on such Bank any other condition; and the result of any of the foregoing is to increase the cost to such Bank, by an amount which such Bank reasonably deems to be material, of making, converting into, continuing or maintaining Eurodollar Loans or to reduce any amount receivable hereunder in respect thereof then, in any such case, the Borrower shall as promptly as practicable pay such Bank, upon its demand, any additional amounts necessary to compensate such Bank for such increased cost or reduced amount receivable; provided, that the Borrower shall not be liable for any such amounts incurred by such Bank more than 180 days prior to the date of such Bank's notification to the Borrower. If any Bank becomes entitled to claim any additional amounts pursuant to this subsection, it shall as promptly as practicable notify the Borrower, through the Agent, of the event by reason of which it has become so entitled. A certificate describing in reasonable detail the determination of any additional amounts payable pursuant to this subsection submitted by such Bank, through the Agent, to the Borrower shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment of the Notes and all other amounts payable hereunder. If any amount is refunded to such Bank, such Bank will reimburse Borrower for amounts paid in respect of the refunded amount. (b) In the event that any Bank shall have determined that any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Bank or any corporation controlling such Bank with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof does or shall have the effect of reducing the rate of return on such Bank's or such corporation's capital as a consequence of its obligations hereunder to a level below that which such Bank or such corporation could have achieved but for such change or compliance (taking into consideration such Bank's or such corporation's policies with respect to capital adequacy) by an amount reasonably deemed by such Bank to be material, then from time to time, after submission as promptly as practicable by such Bank to the Borrower (with a copy to the Agent) of a written request therefor, the Borrower shall pay to such Bank such additional amount or amounts as will compensate such Bank for such reduction. 18

(c) Each Bank agrees that it will use reasonable efforts in order to avoid or to minimize, as the case may be, the payment by the Borrower of any additional amount under subsections 2.9(a) and (b); provided, however, that no Bank shall be obligated to incur any expense, cost or other amount in connection with utilizing such reasonable efforts. Notwithstanding any other provision of this Section 2.9, no Bank shall apply the provisions of subsections 2.9(a) or (b) hereof with respect to the Borrower if it shall not at the time be the general policy or practice of the Bank exercising its rights hereunder to apply the provisions similar to those of this Section 2.9 to other Borrower in substantially similar circumstances under substantially comparable provisions of other credit agreements. 2.10 Taxes. (a) All payments made by the Borrower under this Agreement and the Notes shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding, in the case of the Agent and each Bank, net income taxes and franchise or gross receipts taxes (imposed in lieu of net income taxes) imposed on the Agent or such Bank, as the case may be, as a result of a present or former connection between the jurisdiction of the government or taxing authority imposing such tax and the Agent or such Bank or any political subdivision or taxing authority thereof or therein (all such non-excluded taxes, levies, imposts, duties, charges, fees, deductions and withholdings being hereinafter called "Taxes"). Except as provided in Section 2.10(c) and the penultimate sentence of this Section 2.10(a), if any Taxes are required to be withheld from any amounts payable to the Agent or any Bank hereunder or under the Notes, the amounts so payable to the Agent or such Bank shall be increased to the extent necessary to yield to the Agent or such Bank (after payment of all Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement and the Notes. Whenever any Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the Agent for its own account or for the account of such Bank, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to the Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Agent and the Banks for any incremental taxes, interest or penalties that may become payable by the Agent or any Bank as a result of any such failure. If as a result of a payment by the Borrower of Taxes pursuant to this subsection a Bank receives a tax benefit or tax savings such as by receiving a credit against, refund of, or reduction in Taxes which such Bank would not have received but for the payment by the Borrower of Taxes pursuant to this subsection, then such Bank shall promptly pay to the Borrower the amount of such credit, refund, reduction or any other similar item. The agreements in this subsection shall survive the termination of this Agreement and the payment of the Notes and all other amounts payable hereunder. 19

(b) Each Bank that is not incorporated under the laws of the United States of America or a state thereof agrees that it will deliver to the Borrower and the Agent (i) two duly completed copies of United States Internal Revenue Service Form W-8ECI or W-8BEN or W-8IMY or successor applicable form, as the case may be, and (ii) an Internal Revenue Service Form W-8 or W-9 or successor applicable form. Each such Bank also agrees to deliver to the Borrower and the Agent two further copies of the said Form W-8ECI or W-8BEN or W-8IMY and Form W-8 or W-9, or successor applicable forms or other manner of certification, as the case may be, on or before the date that any such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrower, and such extensions or renewals thereof as may reasonably be requested by the Borrower or the Agent, unless in any such case an event (including, without limitation, any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Bank from duly completing and delivering any such form with respect to it and such Bank so advises the Borrower and the Agent. Such Bank shall certify (i) in the case of a Form W-8ECI or W-8BEN or W-8IMY, that it is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes and (ii) in the case of a Form W-8 or W-9, that it is entitled to an exemption from United States backup withholding tax. Each Bank shall deliver to the Borrower and the Agent, with respect to Taxes imposed by any Governmental Authority other than the United States of America, similar forms, if available (or the information that would be contained in similar forms if such forms were available), to the forms which are required to be provided under this subsection with respect to Taxes of the United States of America. (c) The Borrower shall not be required to pay any additional amounts to the Agent or any Bank in respect of payments of United States withholding tax or other Taxes made by the Borrower which are consistent with the forms and information delivered to the Borrower and the Agent or if the payment of such amounts would not have arisen but for a failure by the Agent or such Bank to comply with the requirements of subsection 2.10(b) or the Agent or such Bank did not timely deliver to the Borrower the forms listed or described in subsection 2.10(b) or did not take such other steps as reasonably may be available to it under applicable tax laws and any applicable tax treaty or convention to obtain an exemption from, or reduction (to the lowest applicable rate) of, such United States withholding tax and other Taxes or, if such steps were taken, the information was not timely and duly delivered to Borrower. 2.11 Indemnity. The Borrower agrees to indemnify each Bank and to hold each Bank harmless from any loss or expense which such Bank may sustain or incur as a consequence of (a) default by the Borrower in payment when due of the principal amount of or interest on any Eurodollar Loan, (b) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (c) default by the Borrower in making any prepayment after the Borrower has given a notice thereof in accordance with the provisions of this Agreement or (d) the making of a prepayment of Eurodollar Loans on a day which is not the last day of an Interest Period with respect thereto, including, without limitation, in each case, any such loss or expense arising from the reemployment of funds obtained by it or from fees payable to terminate the deposits from which such funds were obtained. This covenant shall survive the termination of this Agreement and the payment of the Notes and all other amounts payable hereunder. 20

2.12 Pro Rata Treatment, etc. Except as required under Section 2.8, each Borrowing, each payment or prepayment of principal of the Loans, each payment of interest on the Loans, and each conversion of Loans shall be made pro rata among the Banks in accordance with their respective Pro-Rata Percentages. 2.13 Payments. (a) The Borrower shall make each payment (including principal of or interest on any Loan or any Fees or other amounts) hereunder not later than 12:00 (noon), Philadelphia time, on the date when due in Dollars to the Agent at its offices at 1600 Market Street, Philadelphia, Pennsylvania, or at such other place as may be designated by the Agent, in immediately available funds. (b) Whenever any payment (including principal of or interest on any Loan or any Fees or other amounts) hereunder shall become due, or otherwise would occur, on a day that is not a Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of interest or Fees, if applicable. 2.14 Conversion and Continuation Options. The Borrower shall have the right at any time upon prior irrevocable notice to the Agent (i) not later than 11:00 a.m., Philadelphia time, on the Business Day of conversion, to convert any Eurodollar Loan to a Base Rate Loan, (ii) not later than 11:00 a.m., Philadelphia time, three Business Days prior to conversion or continuation, (y) to convert any Base Rate Loan into a Eurodollar Loan, or (z) to continue any Eurodollar Loan as a Eurodollar Loan for any additional Interest Period, and (iii) not later than 11:00 a.m., Philadelphia time, three Business Days prior to conversion, to convert the Interest Period with respect to any Eurodollar Loan to another permissible Interest Period, subject in each case to the following: (a) a Eurodollar Loan may not be converted at a time other than the last day of the Interest Period applicable thereto; (b) any portion of a Loan maturing or required to be repaid in less than one month may not be converted into or continued as a Eurodollar Loan; (c) no Eurodollar Loan may be continued as such and no Base Rate Loan may be converted to a Eurodollar Loan when any Default or Event of Default has occurred and is continuing; (d) any portion of a Eurodollar Loan that cannot be converted into or continued as a Eurodollar Loan by reason of paragraph 2.14(b) or 2.14(c) automatically shall be converted at the end of the Interest Period in effect for such Loan to a Base Rate Loan; (e) if by the third Business Day prior to the last day of any Interest Period for Eurodollar Loans, the Borrower has failed to give notice of conversion or continuation as described in this subsection, the Agent shall give notice thereof to the Banks and such portion of the Loans shall be automatically converted to Base Rate Loans on the last day of such then expiring Interest Period; and 21

(f) each request by the Borrower to convert or continue any portion of a Loan shall constitute a representation and warranty that each of the representations and warranties made by the Borrower herein is true and correct in all material respects on and as of such date as if made on and as of such date. Accrued interest on a Loan (or portion thereof) being converted shall be paid by the Borrower at the time of conversion. SECTION 3. REPRESENTATIONS AND WARRANTIES To induce the Banks to enter into this Agreement, and to make the Loans, the Borrower hereby represents and warrants to the Agent and each Bank that: 3.1 Financial Condition. (a) The audited consolidated balance sheet of the Borrower and its Subsidiaries as at December 31, 2002 and the related consolidated statements of income and of cash flows for the fiscal year ended on such date, and the consolidated balance sheet as at March 31, 2003 and the statements of income and cash flow of the Borrower and its Subsidiaries for the three month period ended March 31, 2003, copies of all of which have heretofore been furnished to each Bank, present fairly the consolidated financial condition of the Borrower as at such dates, and the consolidated results of its operations and its consolidated cash flows for the periods covered thereby. All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved. Neither the Borrower nor any of its Subsidiaries had, at the date of the most recent balance sheet referred to above, any material Contingent Obligation, liability for taxes, or any long-term lease or unusual forward or long-term commitment, including, without limitation, any interest rate or foreign currency swap or exchange transaction, which is required by GAAP to be but is not reflected in the foregoing statements or in the notes thereto. (b) (i) As of the Closing Date and after giving effect to this Agreement and the Loans to be made on the Closing Date, the Borrower is Solvent. (ii) The Borrower does not intend to incur debts beyond its ability to pay such debts as they mature, taking into account the timing of and amounts of cash to be received by it and the timing of the amounts of cash to be payable on or in respect of its Debt. 3.2 No Adverse Change. Since December 31, 2002, there has been no development or event which has had a Material Adverse Effect. 3.3 Existence; Compliance with Law. The Borrower (a) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, (b) has the corporate power and authority, and the legal right, to own and operate its property, to lease the property it operates as lessee and to conduct the business in which it is currently engaged, (c) is duly qualified as a foreign entity and in good standing under the laws of each jurisdiction where its ownership, lease or operation of property or the conduct of its business requires such qualification, except to the extent that the failure to be so qualified would not, in the aggregate, have a Material Adverse Effect and (d) is in compliance with all Requirements of Law the non-compliance with which would have a Material Adverse Effect. 22

3.4 Corporate Power; Authorization; Enforceable Obligations. The Borrower has the corporate power, authority, and legal right, to make, deliver and perform this Agreement, the Notes, the other Loan Documents to which it is a party and the Purchase Agreement and to borrow hereunder and has taken all necessary corporate action to authorize the borrowings on the terms and conditions of this Agreement and the Notes and to authorize the execution, delivery and performance of this Agreement, the Notes, the other Loan Documents to which it is a party and the Purchase Agreement. No consent or authorization of, filing with or other act by or in respect of, any Governmental Authority or any other Person (including stockholders and creditors of the Borrower) is required in connection with the borrowings hereunder or with the execution, delivery, performance, validity or enforceability of this Agreement, the Notes, the other Loan Documents or the Purchase Agreement. This Agreement and the Purchase Agreement have been, and each Note and other Loan Document will be, duly executed and delivered on behalf of the Borrower. Each of this Agreement and the Purchase Agreement constitutes, and each Note and other Loan Document when executed and delivered will constitute, a legal, valid and binding obligation of the Borrower enforceable against the Borrower in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or similar laws affecting the enforcement of creditors' rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law). 3.5 No Legal Bar. The execution, delivery and performance of this Agreement, the Notes and the other Loan Documents and the Purchase Agreement by the Borrower, the borrowings hereunder and the use of the proceeds thereof and the purchase by the Borrower of its Capital Stock pursuant to the Purchase Agreement will not violate any Requirement of Law or Contractual Obligation of the Borrower or of any of the Subsidiaries and will not result in, or require, the creation or imposition of any Lien on any of its or their respective properties or revenues pursuant to any such Requirement of Law or Contractual Obligation. 3.6 No Material Litigation. Except as set forth on Schedule 3.6, no litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of the Borrower, threatened against the Borrower or against any of the properties or revenues of the Borrower or against any Plan (a) with respect to this Agreement, the Notes or the other Loan Documents or any of the transactions contemplated hereby, or (b) as to which there is a reasonable likelihood of an adverse determination and which, if adversely determined, would have a Material Adverse Effect. 3.7 No Default. The Borrower is not in default under or with respect to any of its Contractual Obligations, including without limitation, those under the Purchase Agreement, in any respect which would have a Material Adverse Effect. No Event of Default has occurred and is continuing. 23

3.8 Taxes. The Borrower has filed or caused to be filed all tax returns which are required to be filed (or has obtained authorized extensions for such filings) and has paid all taxes shown to be due and payable on said returns or on any assessments made against it or any of its property and all other taxes, fees or other charges imposed on it or any of its property by any Governmental Authority (other than any the amount or validity of which are currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the Borrower, as the case may be); no material tax Lien has been filed against the Borrower, and, to the knowledge of the Borrower, no claim is being asserted, with respect to any such tax, fee or other charges. 3.9 Federal Regulations. No part of the proceeds of any Loans will be used for "purchasing" or "carrying" any "margin stock" within the respective meanings of each of the quoted terms under Regulation U or for any purpose which violates the provisions of Regulation U. If requested by any Bank or the Agent, the Borrower will furnish to the Agent and each Bank a statement to the foregoing effect in conformity with the requirements of FR Form U-l referred to in said Regulation U. No part of the proceeds of the Loans hereunder will be used for any purpose which violates, or which is inconsistent with, the provisions of Regulation X. 3.10 ERISA. (a) The Borrower and each Commonly Controlled Entity have operated and administered each Plan in compliance with all applicable laws except for such instances of noncompliance as have not resulted in and could not reasonably be expected to result in a Material Adverse Effect. Neither the Borrower nor any Commonly Controlled Entity has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in Section 3 of ERISA), and no event, transaction or condition has occurred or exists that would reasonably be expected to result in the incurrence of any such liability by the Borrower or any Commonly Controlled Entity, or in the imposition of any Lien on any of the rights, properties or assets of the Borrower or any Commonly Controlled Entity, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or 412 of the Code, other than such liabilities or Liens as would not individually or in the aggregate have a Material Adverse Effect. (b) The present value of the accrued benefit liabilities under each of the Plans (other than Multiemployer Plans), determined as of the end of such Plan's most recently ended plan year on the basis of the actuarial assumptions specified for funding purposes in such Plan's most recent actuarial valuation report, did not exceed the aggregate current value of the assets of such Plan allocable to such benefit liabilities. The term "benefit liabilities" has the meaning specified in section 4001 of ERISA and the terms "current value" and "present value" have the meaning specified in Section 3 of ERISA. (c) The Borrower and its Commonly Controlled Entities have not incurred any withdrawal liabilities (and are not subject to contingent withdrawal liabilities) under Section 4201 or 4204 of ERISA in respect of Multiemployer Plans that individually or in the aggregate would have a Material Adverse Effect. To the best of the Borrower's knowledge, such Multiemployer Plans are neither in Reorganization as defined in Section 4241 of ERISA nor Insolvent. (d) The expected post-retirement benefit obligation (determined as of the last day of the Borrower's most recently ended fiscal year in accordance with Financial Accounting Standards Board Statement No. 106, without regard to liabilities attributable to continuation coverage mandated by section 4980B of the Code) of the Borrower and its Subsidiaries, together with the liabilities referred to in subsection (a) and (c) hereof would not have a Material Adverse Effect. 24

3.11 Investment Company Act; Public Utility Holding Company Act. Except as set forth on Schedule 3.11, the Borrower is not (a) an "investment company", or a company "controlled" by an "investment company", within the meaning of the Investment Company Act of 1940, as amended; (b) a "holding company" or a "subsidiary company" of a "holding company" or an "affiliate" of either a "holding company" or a "subsidiary company" within the meaning of the Public Utility Holding Company Act of 1935, as amended, or (c) subject to any other federal or state law or regulation which purports to restrict or regulate its ability to borrow money. 3.12 Purpose of Loans. The proceeds of the Loans shall be used by the Borrower solely to finance the cost of the AquaSource Acquisition pursuant to and in accordance with the terms of the Purchase Agreement, a true and correct copy of which has been delivered to the Agent. 3.13 Environmental Matters(a) .

(d) Notwithstanding any provision herein to the contrary or in the other Loan Documents, any proceeds received by the Agent from any payment made by the Borrower under this Agreement or the other Loan Documents after the occurrence of an Event of Default, or received by the Agent from the foreclosure, sale, lease, collection upon, realization of or other disposition of any collateral which may have been provided to the Agent for the obligations of the Borrower hereunder after the occurrence of an Event of Default (including without limitation insurance proceeds), shall be applied by the Agent as follows, unless otherwise agreed by all the Banks: (i) first, to reimburse the Agent for out-of-pocket costs, expenses and disbursements, including without limitation reasonable attorneys' fees and legal expenses, incurred by the Agent in connection with collection of any obligations of the Borrower under any of the Loan Documents; (ii) second, to accrued and unpaid interest on the Loans; (iii) third, to the principal amount of the Loans then outstanding; (iv) fourth, to fees payable under this Agreement or any of the other Loan Documents (ratably according to the respective amounts then outstanding); (v) fifth, to the repayment of all other indebtedness then due and unpaid of the Borrower to the Banks incurred under this Agreement or any of the other Loan Documents, whether of principal, interest, fees, expenses or otherwise (ratably according to the respective amounts then outstanding); and (vi) the balance, if any, as required by law. (e) Each Bank agrees that (i) if at any time it shall receive the proceeds of any collateral or any proceeds thereof or (ii) if after the occurrence of an Event of Default it shall receive any payment on account of the Loans or any other amounts owing hereunder or under the other Loan Documents (in either case other than through application by the Agent in accordance with subsection 7.2(d)), it shall promptly turn the same over to the Agent for application in accordance with the terms of subsection 7.2(d).

SECTION 8. THE AGENT 8.1 Appointment. Each Bank hereby irrevocably designates and appoints PNC as the Agent of such Bank under this Agreement. Each such Bank irrevocably authorizes the Agent, as the agent for such Bank to take such action on its behalf under the provisions of this Agreement and to exercise such powers and perform such duties as are expressly delegated to the Agent by the terms of this Agreement, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, the Agent shall not have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Bank, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or otherwise exist against the Agent. The Agent agrees to act as the Agent on behalf of the Banks to the extent provided in this Agreement. 8.2 Delegation of Duties. The Agent may execute any of its duties under this Agreement by or through agents or attorneys-in-fact and shall be entitled to engage and pay for the advice and services of counsel concerning all matters pertaining to such duties. The Agent shall not be responsible to the Banks for the negligence or misconduct of any agents or attorneys in-fact selected by it with reasonable care. 8.3 Exculpatory Provisions. Neither the Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be (i) liable to any of the Banks for any action lawfully taken or omitted to be taken by them or such Person under or in connection with this Agreement (except for their or such Person's own gross negligence or willful misconduct) or (ii) responsible in any manner to any of the Banks for any recitals, statements, representations or warranties made by the Borrower or any officer thereof contained in this Agreement or in any certificate, report, statement or other document referred to or provided for in, or received by the Agent under or in connection with, this Agreement or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement, the Notes or the other Loan Documents or for any failure of the Borrower to perform its obligations hereunder or thereunder. The Agent shall not be under any obligation to any Bank to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or the other Loan Documents, or to inspect the properties, books or records of the Borrower. 8.4 Reliance by Agent. The Agent shall be entitled to rely, and shall be fully protected in relying, upon any Note, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Borrower), independent accountants and other experts selected by the Agent. The Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Agent. The Agent shall be fully justified in failing or refusing to take any action under this Agreement unless it shall first receive such advice or concurrence of the Required Banks as they deem appropriate or they shall first be indemnified to its satisfaction by the Banks against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement, the Notes and the other Loan Documents in accordance with a request of the Required Banks, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Banks and all future holders of the Notes. 41

8.5 Notice of Default. The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless they have received notice from a Bank or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a "notice of default". In the event that the Agent receives such a notice, the Agent shall give notice thereof to the Banks. The Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Banks; provided that unless and until the Agent shall have received such directions, the Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Banks. 8.6 Non-Reliance on Agent and Other Banks. Each Bank expressly acknowledges that neither the Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates has made any representations or warranties to it and that no act by the Agent hereinafter taken, including any review of the affairs of the Borrower, shall be deemed to constitute any representation or warranty by the Agent to any Bank. Each Bank represents to the Agent that it has, independently and without reliance upon the Agent or any other Bank, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Borrower and made its own decision to make its Loans hereunder and enter into this Agreement. Each Bank also represents that it will, independently and without reliance upon the Agent or any other Bank, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Borrower. Except for notices, reports and other documents expressly required to be furnished to the Banks by the Agent hereunder, the Agent shall not have any duty or responsibility to provide any Bank with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of the Borrower which may come into the possession of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates. 8.7 Indemnification. The Banks agree to indemnify the Agent in its capacity as such (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so), ratably according to their respective Pro-Rata Percentages, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever which may at any time (including, without limitation, at any time following the payment of the Notes) be imposed on, incurred by or asserted against the Agent in any way relating to or arising out of this Agreement, the other Loan Documents, or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Agent under or in connection with any of the foregoing; provided that no Bank shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting solely from the Agent's gross negligence or willful misconduct. The agreements in this Section 8.7 shall survive the payment of the Notes and all other amounts payable hereunder. 42

8.8 Agent in its Individual Capacity. The Agent and its Affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrower as though it was not the Agent hereunder. With respect to its Loans made or renewed by it and any Note issued to it, the Agent shall have the same rights and powers under this Agreement as any Bank and may exercise the same as though it were not the Agent, and the terms "Bank" and "Banks" shall include the Agent in its individual capacity. 8.9 Successor Agent. The Agent may resign as Agent upon sixty (60) days' notice to the Banks and the Borrower. If such Agent shall resign as Agent under this Agreement, then the Required Banks shall appoint from among the Banks a successor agent for the Banks, which appointment shall be subject to the approval of the Borrower (which approval shall not be unreasonably withheld), whereupon such successor agent shall succeed to the rights, powers and duties of an Agent, and the term "Agent" shall mean such successor agent effective upon its appointment, and the former Agent's rights, powers and duties as Agent shall be terminated, without any other or further act or deed on the part of such former Agent or any of the parties to this Agreement or any holders of the Notes. After any retiring Agent's resignation as Agent, the provisions of this Section 8.9 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement. 8.10 Beneficiaries. Except as expressly provided herein, the provisions of this Section 8 are solely for the benefit of the Agent and the Banks, and the Borrower shall not have any rights to rely on or enforce any of the provisions hereof. In performing their functions and duties under this Agreement the Agent shall act solely as agent of the Banks and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for the Borrower. 8.11 USA Patriot Act. Each Bank or assignee or participant of a Bank that is not incorporated under the laws of the United States of America or a state thereof (and is not excepted from the certification requirement contained in Section 313 of the USA Patriot Act and the applicable regulations because it is both (i) an affiliate of a depository institution or foreign bank that maintains a physical presence in the United States or foreign country, and (ii) subject to supervision by a banking authority regulating such affiliated depository institution or foreign bank) shall deliver to the Agent the certification, or, if applicable, recertification, certifying that such Bank is not a "shell" and certifying to other matters as required by Section 313 of the USA Patriot Act and the applicable regulations: (1) within 10 days after the Closing Date, and (2) at such other times as are required under the USA Patriot Act.

Any such waiver and any such amendment, supplement or modification shall apply equally to each of the Banks and shall be binding upon the Borrower, the Banks, the Agent and all future holders of the Notes. In the case of any waiver, the Borrower, the Banks and the Agent shall be restored to their former position and rights hereunder and under the outstanding Notes, and any Default or Event of Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon. 43

The Register shall be available for inspection by the Borrower and any Bank, at any reasonable time and from time to time upon reasonable prior notice. 47

Such new Notes shall be dated the date of the surrendered Note which it replaces and shall otherwise be in substantially the form of Exhibit A hereto. Canceled Notes shall be returned to the Borrower. (f) Each Bank may without the consent of the Borrower or the Agent sell participations to one or more banks or other entities (each a "Participant") in all or a portion of its rights and obligations under this Agreement (including all or a portion of the Loan owing to it and the Note held by it); provided, however, that (i) such Bank's obligations under this Agreement shall remain unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Bank shall remain the holder of any such Note for all purposes under this Agreement, (iv) the Borrower, the Agent and the other Banks shall continue to deal solely and directly with such Bank in connection with such Bank's rights and obligations under this Agreement, (v) in any proceeding under the Bankruptcy Code such Bank shall be, to the extent permitted by law, the sole representative with respect to the obligations held in the name of such Bank whether for its own account or for the account of any Participant and (vi) such Bank shall retain the sole right to enforce the obligations of the Borrower relating to the Loan and to approve any amendment, modification or waiver of any provision of this Agreement or the Note held by such Bank other than any such amendment, modification or waiver with respect to any Loan or Commitment in which such Participant has an interest and which is described in subsection 9.1(a) hereof. (g) If amounts outstanding under this Agreement and the Notes are due or unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall be deemed to have the right of set-off in respect of its participating interest in amounts owing under this Agreement and any Note to the same extent as if the amount of its participating interest were owing directly to it as a Bank under this Agreement or any Note, provided that in purchasing such participation such Participant shall be deemed to have agreed to share with the Banks the proceeds thereof as provided in Section 9.8. The Borrower also agrees that each Participant shall be entitled to the benefits of Sections 2.9, 2.10, 2.11 and 9.5 with respect to its participation in the Loan outstanding from time to time; provided, that no Participant shall be entitled to receive any greater amount pursuant to such Sections than the Bank selling the participation would have been entitled to receive in respect of the amount of the participation transferred by such Bank to such Participant had no such transfer occurred. (h) If any Participant is organized under the laws of any jurisdiction other than the United States or any state thereof, the Bank selling the participation, concurrently with the sale of a participating interest to such Participant, shall cause such Participant (i) to represent to the Bank selling the participation (for the benefit of such Bank, the other Banks, the Agent and the Borrower) that under applicable law and treaties no taxes will be required to be withheld by the Agent, the Borrower or the Bank selling the participation with respect to any payments to be made to such Participant in respect of its participation in the Loan and (ii) to agree (for the benefit of such Bank, the other Banks, the Agent and Borrower) that it will deliver the tax forms and other documents required to be delivered pursuant to Section 2.10 and comply from time to time with all applicable U.S. laws and regulations with respect to withholding tax exemptions. 48

(i) Any Bank may at any time assign all or any portion of its rights under this Agreement and the Note issued to it to a Federal Reserve Bank; provided that no such assignment shall release a Bank from any of its obligations hereunder. 9.7 Confidentiality. The Banks agree that they will maintain all information and financial statements provided to them or otherwise obtained by them with respect to the Borrower and its Subsidiaries confidential and that they will not disclose the same or use it for any purposes; provided that nothing herein shall prevent any Bank from disclosing any such information (a) to the Agent or any other Bank, (b) to any prospective assignee or participant in connection with any assignment or participation of Loans permitted by this Agreement, (c) to its employees, directors, agents, attorneys, accountants and other professional advisers, provided that any such person is advised by such Bank that such information is subject to the confidentiality limitations of this Section, (d) upon the request or demand of any Governmental Authority having jurisdiction over such Bank, (e) in response to any order of any court or other Governmental Authority or as may otherwise be required pursuant to any Requirement of Law, provided that the Borrower has (unless prohibited by the terms of any such order or requirement) been advised at least ten (10) days (or if such is not possible or practicable, such lesser number of days as is possible or practicable under the circumstances) prior to such disclosure of the existence of such order or requirement, (f) which has been publicly disclosed other than in breach of this Agreement, or (g) in connection with the exercise of any remedy hereunder or under the Notes. 9.8 Adjustments; Set-off. (a) If any Bank (a "benefited Bank") shall at any time receive any payment of all or part of its Loan, or interest thereon, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in subsection 7(g), or otherwise), in a greater proportion than any such payment to or collateral received by any other Bank, if any, in respect of such other Bank's Loan, or interest thereon, being paid in respect of Loans being repaid simultaneously therewith or Loans required hereby to be paid proportionately, such benefited Bank shall purchase for cash from the other Banks such portion of each such other Bank's Loan, or shall provide such other Banks with the benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause such benefited Bank to share the excess payment or benefits of such collateral or proceeds ratably with each of the Banks; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such benefited Bank, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. The Borrower agrees that each Bank so purchasing a portion of another Bank's Loan may exercise all rights of payment (including, without limitation, rights of set-off) with respect to such portion as fully as if such Bank were the direct holder of such portion. 49

(b) In addition to any rights and remedies of the Banks provided by law, upon the occurrence of an Event of Default, each Bank shall have the right, without prior notice to the Borrower, any such notice being expressly waived by the Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by the Borrower hereunder or under the Notes (whether at the stated maturity, by acceleration or otherwise) to set-off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Bank to or for the credit or the account of the Borrower. Each Bank agrees promptly to notify the Borrower and the Agent after any such set-off and application made by such Bank, that the failure to give such notice shall not affect the validity of such set-off and application. 9.9 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument. A set of the copies of this Agreement signed by all the parties shall be lodged with the Borrower and each of the Banks. 9.10 Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 9.11 Integration. This Agreement represents the agreement of the Borrower, the Agent and the Banks with respect to the subject matter hereof, and there are no promises, undertakings, representations or warranties by the Agent or any Bank relative to subject matter hereof not expressly set forth or referred to herein or in the Notes or the other Loan Documents. 9.12 GOVERNING LAW.

The Borrower hereby acknowledges that: (a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement, the Notes and the other Loan Documents; (b) neither the Agent nor any Bank has any fiduciary relationship to the Borrower, and the relationship between the Agent and the Banks, on one hand, and the Borrower, on the other hand, is solely that of debtor and creditor; and (c) no joint venture exists among the Banks or between the Borrower and the Banks. 9.15 WAIVERS OF JURY TRIAL.
