ARTICLE I.

Form, Authentication and Delivery of
the Bonds

Section 1. There shall be a twenty-fifth series of bonds, limited in aggregate principal amount, designated as “Philadelphia Suburban Water Company First Mortgage Bonds, 9.89% Series due 2008”, a twenty-sixth series of bonds, limited in aggregate principal amount, designated “Philadelphia Suburban Water Company First Mortgage Bonds, 9.93% Series due 2013” and a twenty-seventh series of bonds, limited in aggregate principal amount, designated “Philadelphia Suburban Water Company First Mortgage Bonds, 9.97% Series due 2018” (sometimes the twenty-fifth, twenty-sixth and twenty-seventh series of bonds are herein referred to individually as the “9.89% Series due 2008”, “9.93% Series due 2013” and “9.97% Series due 2018”, respectively, and collectively as the “Bonds”).

The Bonds shall be dated as of the date of issue (except that if any bond shall be issued prior to December 1, 1988 in exchange for any other bond, it shall be dated the date of the bond for which it is exchanged, and if any such bond shall be issued on any interest payment date it shall be dated as of the day next following such interest payment date), shall mature on and shall bear interest at the rate set forth below:

Interest shall be payable semi-annually on the first day of June and the first day of December of each year. The Bonds shall bear interest from the interest payment date next preceding the date thereof, except that Bonds dated prior to December 1, 1988, shall bear interest from the date thereof and except as otherwise provided in Section 5 of Article II of the Original Indenture with respect to Bonds issued upon transfer or exchange of Bonds on which interest is in default.

The Bonds shall be issuable only as registered bonds without coupons, shall be in the form hereinabove recited, in the denomination of Five Thousand Dollars ($5.000) or any multiple thereof, shall be lettered “R”, and shall bear such numbers as the Company may reasonably require.

The principal of, and premium, if any, and interest on the Bonds shall be payable at the office of the Trustee in the City of Philadelphia, Pennsylvania, in such coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts; provided, however, that each installment of interest may be paid by check to the order of the person entitled thereto, mailed to such person’s address as the same appears on the 

books maintained for such purpose by or on behalf of the Company, or by bank wire transfer of immediately available funds pursuant to instructions incorporated in an agreement between such person and the Trustee or the Company.

The person in whose name any Bond is registered at the close of business on any record date (as hereinafter defined) with respect to any interest payment date shall be entitled to receive the interest payable on such interest payment date notwithstanding the cancellation of such Bond upon any transfer or exchange subsequent to the record date and prior to such interest payment date; provided, however, that if and to the extent the Company shall default in the payment of the interest due on such interest payment date, such defaulted interest shall be paid to the persons in whose names outstanding Bonds are registered at the close of business on a subsequent record date established by notice given by mail by or on behalf of the Company to the holders of Bonds not less than fifteen days preceding such subsequent record date, such record date to be not less than ten days preceding the date of payment of such defaulted interest. The term “record date” as used in this Section 1 with respect to any regular interest payment date shall mean the fifteenth day of the calendar month preceding such interest payment date if such fifteenth day is a business day; if such fifteenth day is not a business day, the record date shall be the next preceding business day.

Exchange of any Bonds shall be effected in accordance with the applicable provisions of Sections 7,  8 and 9 of Article II of the Original Indenture. The text of the Bonds and of the certificate of the Trustee upon such Bonds shall be, respectively, substantially of the tenor and effect hereinbefore recited.

Section 2. The Bonds shall be redeemable either at the option of the Company pursuant to the provisions of the Original Indenture or of this Twenty-Fourth Supplemental Indenture pursuant to any provision of the Original Indenture or of this Twenty-Fourth Supplemental Indenture requiring such redemption,  either as a whole at any time prior to maturity, or in part from time to time on any Interest Payment Date, except that in the case of redemption at the option of the Company, no Bonds may be redeemed in such manner prior to June 1,  2003. The Bonds shall be subject to mandatory redemption (i) in connection with the sale to or other acquisition by or on behalf of one or more governments or municipal corporations or other governmental subdivisions, bodies, authorities or agencies of all or substantially all of the property of the Company, or (ii) in connection with any voluntary or involuntary liquidation, dissolution or winding up of the Company, occurring in connection with or subsequent to the acquisition of all or substantially all of the stock of the Company ordinarily entitled to voting rights by or on behalf of one or more governments or municipal corporations or other governmental subdivisions, bodies, authorities or agencies. The Bonds are redeemable in such coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts,  at one hundred per cent (100%) of the principal amount thereof, together with interest accrued thereon to the date fixed for redemption. If redeemed otherwise than in accordance with the second preceding sentence, the Bonds of each series are redeemable in like coin and currency at a redemption price (the “Optional Redemption Price”) equal to the principal amount to be redeemed plus interest thereon to the date of redemption plus a premium equal to the amount by which the present value. as of the date of redemption, of all remaining payments of principal and interest thereon to stated maturity using the Applicable Treasury Rate (as hereinafter defined) as a discount factor exceeds the outstanding principal amount to be redeemed of the particular series of Bonds. No premium shall be payable if such difference is less than or equal to zero. For the purposes hereof. the Applicable Treasury Rate means the yield on the United States Treasury obligations, determined with reference to the Statistical Release, whose maturity most closely coincides with the maturity of the Bonds being redeemed. For the purposes hereof, the Statistical Release means the statistical release designated “H.l5 (519)” which is published weekly by the Federal Reserve System or if such release shall cease to be published by the Federal Reserve System or if such release does not set forth the interest rate of United States Treasury obligations with maturities permitting the calculation of the premium, then any comparable release of the Federal Reserve System which sets forth the interest rate of United States Treasury obligations with maturities permitting the calculation of the premium,  or if the Federal  Reserve System shall 

not publish such comparable release then such other similar publicly available release which is acceptable to the Company and the holders of 662/3% of outstanding Bonds.

Any redemption of the Bonds shall be effected in accordance with the provisions of Article V of the Original Indenture except that, notwithstanding any other provisions to the contrary,  whenever less than all the outstanding Bonds of any series are to be redeemed, then the Bonds of such series to be redeemed shall not be selected by lot as provided in Section 2 of Article V of the Original Indenture but (in the absence of an agreement as hereinafter referred to) shall be selected by the Trustee, in accordance with any method which it shall adopt, in such manner that the principal amount of Bonds of such series of each registered owner thereof to be so redeemed shall, except as hereinafter provided, bear to the aggregate principal amount of Bonds of such series at the time to be redeemed the same ratio as is borne by the principal amount of Bonds of such series at the time registered in the name of that owner to the aggregate principal amount of such series of Bonds at the time outstanding; provided, however, that, to the extent. but only to the extent,  that Bonds or portions thereof to be redeemed cannot be selected in the exact ratios above provided by reason of the fact that the application of such ratios would involve the selection of fractional parts of bonds (that is,  portions of principal amounts thereof less than $5,000), the Trustee shall select the principal amount of Bonds of each of the registered owners thereof to be redeemed in such amount as shall be deemed, in the discretion of the Trustee, appropriate to maintain, through successive partial redemptions, the ratios above provided. If an agreement with respect to the selection of Bonds to be redeemed duly executed by the registered owners of all of the outstanding Bonds of any series shall be filed with the Trustee at least ten days prior to the date upon which the publication or mailing of the notice of redemption hereinbefore mentioned is required to be made. the Bonds of said series to be redeemed shall be selected in accordance with the provisions of such agreement.

Section 3. Bonds of the 9.89%  Series due 2008 in the aggregate principal amount of $5,000,000,  bonds of the 9.93% Series due 2013 in the aggregate principal amount of $5,000,000 and bonds of the 9.97% Series due 2018 in the aggregate  principal amount of $5,000,000 may be issued under the provisions of Article IV of the Original Indenture and may forthwith be executed by the Company and delivered to the Trustee and shall be authenticated by the Trustee and delivered to or upon the order of the Company, upon receipt by the Trustee of the resolutions, certificates, opinions and/or other  instruments required to be delivered upon the issue of bonds pursuant to the provisions of the Original Indenture.
