As provided in the Indenture, the bonds may be issued in series for various principal amounts, may bear different dates and mature at different times, may bear interest at different rates and may otherwise vary as in the Indenture provided or permitted. This bond is one of the bonds described in an indenture supplemental to said Indenture known as the "Thirty-Third Supplemental Indenture" dated as of November 15, 1999, and designated therein as "First Mortgage Bonds, 1999 Medium Term Note Series, Subseries __" (the "Bonds of the 1999 Medium Term Note Series"). The Bonds of the 1999 Medium Term Note Series will be issued in fully registered form, without coupons. The Bonds of the 1999 Medium Term Note Series will be deposited with, or on behalf of DTC and registered in the name of a nominee of DTC in the form of one or more global securities (the "Global Bonds") 9 or will remain in the custody of the Trustee pursuant to a Medium-Term Note Certificate Agreement, dated December 2, 1988, between DTC and The Chase Manhattan Bank, which was merged into Chemical Bank, which changed its name to The Chase Manhattan Bank. DTC was created to hold securities of persons who have accounts with DTC ("participants") and to facilitate the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of the participants. Upon the issuance of a Global Bond, DTC or its nominees will credit the respective Bonds of the 1999 Medium Term Note Series represented by such Global Bond to accounts of participants. The accounts to be credited shall be designated by the purchasers. Ownership of beneficial interests in such Global Bonds will be limited to participants or persons that may hold interests through participants. Ownership of beneficial interests by participants in such Global Bonds will be shown on, and the transfer of those ownership interests will be effected only through, records maintained by DTC or its nominee for such Global Bonds. Ownership of beneficial interests in such Global Bonds by persons that hold through participants will be shown on, and the transfer of that ownership interest within such participant will be effected only through, records maintained by such participant. So long as DTC or its nominee is the registered owner of a Global Bond, DTC or such nominee, as the case may be, will be considered the sole owner or holder of those Bonds of the 1999 Medium Term Note Series beneficially owned by other persons for all purposes under the Indenture. Except as set forth below, owners of beneficial interests in such Global Bonds will not be entitled to have the Bonds of the 1999 Medium Term Note Series registered in their names, will not receive or be entitled to receive physical delivery of the Bonds of the 1999 Medium Term Note Series in definitive form and will not be considered the owners or holders thereof under the Indenture. Payment of principal of and any interest on the Bonds of the 1999 Medium Term Note Series registered in the name of or held by DTC or its nominee will be made to DTC or its nominee, as the case may be, as the registered owner or the holder of the Global Bond. Neither the Company, the Trustee nor any paying agent for the Bonds of the 1999 Medium Term Note Series will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Bond or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. Payment of principal or any interest on the Certificated Bonds (as defined below), if any, will be made to the registered owners thereof. The Company expects that DTC, upon receipt of any payment of principal or interest in respect of a permanent Global Bond, will credit immediately participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of such Global Bond as shown on the records of DTC. The Company also expects that payments by participants to owners of beneficial interests in such Global Bond held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in "street name", and will be the responsibility of such participants. 10 A Global Bond may not be transferred except as a whole by DTC to a nominee or a successor of DTC. If DTC is at any time unwilling or unable to continue as depositary and a successor depositary is not appointed by the Company within 90 days, the Company will issue Bonds of the 1999 Medium Term Note Series in definitive registered form (the "Certificated Bonds") in exchange for the Global Bond or Bonds representing such Bonds of the 1999 Medium Term Note Series. In addition, the Company may at any time and in its sole discretion determine not to have some of or all the bonds of the 1999 Medium Term Note Series represented by one or more Global Bonds and, in such event, will issue bonds of the 1999 Medium Term Note Series in definitive registered form in exchange for all of the Global Bonds representing such Bonds of the 1999 Medium Term Note Series. In any such instance, an owner of a beneficial interest in a Global Bond will be entitled to physical delivery of Certificated Bonds represented by such Global Bond equal in amount to that represented by such beneficial interest and to have such Certificated Bonds registered in its name. Payments of principal, premium, if any, and interest shall be made in such coin or currency of the United States as at the time of payment is legal tender for the payment of public and private debts. Payments of interest, other than interest payable at the Maturity Date, or any earlier Redemption Date or Tender Date, will be paid in immediately available funds by wire transfer to the account of Cede & Co., as nominee for DTC, or, in the case of Certificated Bonds, by check mailed to the registered holder of such bond at the address shown in the Register maintained by the Trustee, or at the option of the registered holder, at such place in the United States of America as the registered holder shall designate to the Trustee in writing. Notwithstanding the foregoing, the registered holder of $10,000,000 or more of Certificated Bonds with the same Interest Payment Date shall be entitled to receive payment by wire transfer of immediately available funds, provided that written instructions designating the account number and bank in New York, New York (or other bank consented to by the Company) shall have been received by the Trustee not less than ten (10) days prior to the Record Date for such Interest Payment Date. Once such wire transfer instructions have been received by the Trustee they shall remain in effect unless (i) the Trustee is notified, in writing, of a change thereof not less than ten (10) days prior to the Record Date for an Interest Payment Date; or (ii) the registered holder no longer holds an aggregate principal amount of at least $10,000,000 of Certificated Bonds having the same Interest Payment Date. The principal amount hereof, premium, if any, and interest due on the Redemption Date, Tender Date or at the Maturity Date will be paid on the Redemption Date, Tender Date or at the Maturity Date in immediately available funds by wire transfer to such account at a bank in New York, New York (or such other bank consented to by the Company) as such holder of the bond of the 1999 Medium Term Note Series shall have designated for such payment or for the payment of interest as provided above. Payment to a registered holder of Bonds of the 1999 Medium Term Note Series for which appropriate instructions for payment have not been received by the Trustee not later than ten (10) days prior to the related date of payment shall be made by check mailed by the Trustee to the person entitled thereto at such person's address appearing in the registry maintained by the Trustee. Wire transfer instructions received by the Trustee in connection with the payment of principal, premium, if any, and interest due on the Redemption Date, Tender Date or the Maturity Date of the Bond of the 1999 Medium Term Note Series shall remain in effect unless the Trustee is notified of a change thereof not less than ten (10) days prior to the Redemption Date, Tender Date or Maturity Date. Payment of principal, premium, if any, and interest due on the Redemption Date, Tender Date or the Maturity Date on the Bond of the 1999 Medium Term Note Series shall only be made against presentation and surrender of this bond at a delivery office designated by the Trustee and maintained for that purpose in Dallas, Texas, or at such other office or agency of the Company as the Company shall designate. 11 So long as the Bonds of the 1999 Medium Term Note Series are in book-entry form represented by Global Bonds registered in the name of Cede & Co., or another nominee of DTC, then Cede & Co., or such other nominee of DTC, as the case may be, will be considered the sole owner or holder of the Bonds of the 1999 Medium Term Note Series represented by such Global Bond for the purpose of receiving payment on the Bonds of the 1999 Medium Term Note Series, receiving notices and for all other purposes under the Indenture or the Global Bond. Ownership of beneficial interests in Global Bonds will be limited to persons who have accounts with DTC (the "participants") or persons that may hold interests through participants. Beneficial interests in a Global Bond will be evidenced only by, and transfers thereof will be effected only through, records maintained by DTC. Ownership of beneficial interests in such Global Bonds by persons that hold through participants will be shown on, and the transfer of that ownership interest within such participant will be effected only through, records maintained by such participant. In the case of Certificated Bonds, subject to certain restrictions set forth on the face hereof and in the Indenture, this bond may be transferred at the aforesaid office of the Trustee by surrendering this bond for cancellation, accompanied by a written instrument of transfer in form satisfactory to the Trustee and duly executed by the registered holder hereof in person or by the holder's attorney duly authorized in writing, and thereupon the Trustee will issue in the name of the transferee or transferees, in exchange hereof, a new bond or bonds having identical terms and provisions and having a like aggregate principal amount in authorized denominations, subject to the terms and conditions set forth herein; provided, however, that the Trustee will not be required to register the exchange or transfer of any Bond of the 1999 Medium Term Note Series after the first notice of redemption of such bond has been mailed or after the first notice of Tender (hereinafter defined) of such Bond has been received by the Trustee or during a period beginning at the opening of business ten (10) days preceding an Interest Payment Date. Bonds of the 1999 Medium Term Note Series are exchangeable at said office for other Bonds of the 1999 Medium Term Note Series of other authorized denominations of equal aggregate principal amount and having identical terms and provisions. All such exchanges of Bonds of the 1999 Medium Term Note Series will be free of charge, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge in connection therewith. All bonds of the 1999 Medium Term Note Series surrendered for exchange shall be accompanied by a written instrument of transfer in the form attached hereto to the Trustee and executed by the registered holder in person or by the holder's attorney duly authorized in writing. To the extent permitted by and as provided in the Indenture, modifications or alterations of the Indenture, or of any indenture supplemental thereto, and of the rights and obligations of the Company and of the holders and registered owners of bonds issued and to be issued thereunder may be made with the consent of the Company by an affirmative vote of the holders and registered owners of not less than 75% in principal amount of bonds then outstanding under the Indenture and entitled to vote, at a meeting of the bondholders called and held as provided in the Indenture, and, in case one or more but less than all of the series of bonds then outstanding under the Indenture are so affected, by an affirmative vote of the holders and registered owners of not less than 75% in principal amount of bonds of any series then outstanding under the Indenture and entitled to vote on and affected by such modification or alteration, or by the written consent of the holders and registered owners of such percentages of 12 bonds; provided, however, that no such modification or alteration shall be made which shall reduce the percentage of bonds the consent of the holders or registered owners of which is required for any such modification or alteration or which shall affect the terms of payment of the principal of or interest on the bonds, or permit the creation by the Company of any lien prior to or on a parity with the lien of the Indenture with respect to any property subject to the lien of the Indenture as a first mortgage lien thereon, or which shall affect the rights of the holders or registered owners of less than all of the bonds of any series affected thereby. The Bonds of the 1999 Medium Term Note Series are subject to redemption at the option of the Company on or after the Initial Redemption Date specified on the face hereof (if any), either as a whole or in part, in increments of $1,000 (provided that any remaining principal hereof shall be at least $100,000) on any Interest Payment Date in coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts at the Redemption Price equal to the Initial Redemption Percentage specified on the face hereof of the principal amount hereof, which shall decline on each anniversary of the Initial Redemption Date by the Annual Redemption Reduction Percentage specified on the face hereof of the principal amount to be redeemed until the Redemption Price is 100% of such principal amount, in each case plus accrued interest to the Redemption Date. The Bonds of the 1999 Medium Term Note Series are 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. In such a mandatory redemption, the Bonds of the 1999 Medium Term Note Series 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 Redemption Date. Any redemption shall be effected by notice mailed to the registered owners thereof, as provided in the Indenture, at least thirty (30) days before the Redemption Date, all on the conditions and in the manner provided in the Indenture. If this bond or any portion hereof is called for redemption and payment thereof is duly provided for as specified in the Indenture, interest shall cease to accrue hereon or on such portion, as the case may be, from and after the Redemption Date. In the event of redemption of this bond in part only, a new bond for the unredeemed portion hereof shall be issued in the name of the holder hereof upon the surrender hereof. 14 [Tender Bonds only - This bond is subject to optional tender ("Tender"), in its entirety, by holders thereof on the first Interest Payment Date ("Tender Date") next succeeding the tenth anniversary of the Original Issue Date 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 a tender price ("Tender Price") of one hundred percent (100%) of the principal amount thereof, plus accrued interest to the Tender Date. Any Tender shall be effectuated by (1) notice ("Tender Notice") mailed (by registered mail with return receipt requested or other courier or express delivery service) by the registered owner of a Bond of the 1999 Medium Term Note Series to the Trustee at least thirty (30) days prior to the Tender Date, and (2) presentment to the Trustee of said Bond[s] of the 1999 Medium Term Note Series at least five (5) Business Days prior to the Tender Date. If a Bond of the 1999 Medium Term Note Series which is subject to Tender is tendered and payment thereof is duly provided for, interest shall cease to accrue hereon from and after the Tender Date. By delivery of the Tender Notice, the owner irrevocably agrees to deliver the bond or bonds described therein (if such bonds are in certificated form) to the delivery office of the Trustee at least five (5) Business Days prior to the Tender Date. The determination by the Trustee of a bondholder's compliance with the requirement of the Tender Notice is in its sole discretion and binding on the Company and the holder of the bond or bonds. Any Tender Notice which is determined not to be in compliance with the Thirty-Third Supplemental Indenture shall be of no force and effect. If a holder who gives a Tender Notice shall fail to deliver the bond identified in the Tender Notice to the Trustee at or prior to 10:00 a.m. on the Purchase Date, such bond shall be deemed purchased and shall cease to accrue interest on such Tender Date and the holder thereof shall thereafter be entitled only to payment of the Tender Price therefor and to no other benefits of the Thirty-Third Supplemental Indenture. Notwithstanding anything to the contrary herein, the right of the holders of a bond to tender the bonds shall cease immediately and without further notice from and including the date on which the Trustee notifies the holder of such bond of an acceleration under Article XI of the Indenture.] The principal hereof may be declared or may become due prior to its Maturity Date on the conditions, in the manner and with the effect set forth in the Indenture upon the happening of an event of default, as in the Indenture provided; subject, however, to the right, under certain circumstances, of the registered owners of a majority in principal amount of bonds then outstanding, including the Bonds of the 1999 Medium Term Note Series, to annul such declaration. The Company, the Trustee and any Paying Agent may deem and treat the registered owner of this bond as the absolute owner hereof for the purpose of receiving payment of or on account of the principal hereof and the interest hereon, and for all other purposes, and shall not be affected by any notice to the contrary. 14 When any notice to holders of the Bonds of the 1999 Medium Term Note Series requesting consents, waivers, votes or other actions of such holders is given by the Trustee hereunder at any time that the Bonds of the 1999 Medium Term Note Series are represented by Global Bonds registered in the name of Cede & Co., or another nominee of DTC, such notice shall be sent by the Trustee to DTC with a request that DTC forward (or cause to be forwarded) the notice to the DTC participants so that DTC participants may forward (or cause to be forwarded) the notice to the beneficial owners. The Trustee shall be entitled to rely on any omnibus proxy delivered by DTC and to consider those DTC participants to whose account the Bonds of the 1999 Medium Term Note Series are credited on any record date or special record date, as appropriate, and identified in a listing attached to the omnibus proxy, as owners of the aggregate amount of Bonds of the 1999 Medium Term Note Series set forth on such listing for purposes of any consent, waiver, vote or other action of holders of such Bonds of the 1999 Medium Term Note Series. No recourse shall be had for the payment of the principal of or interest on this bond or for any claim based hereon or otherwise in respect hereof or of the Indenture or of any indenture supplemental thereto against any incorporator or any past, present or future stockholder, officer or director of the Company or of any predecessor or successor corporation, as such, either directly or through the Company, or through any such predecessor or successor corporation or through any receiver or trustee in bankruptcy, by virtue of any constitutional provision, statute or rule of law or equity, or by the enforcement of any assessment or penalty or otherwise; all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released by every holder or registered owner hereof, as more fully provided in the Indenture. The Bonds of the 1999 Medium Term Note Series and related documentation may be amended or supplemented from time to time by the Company without the consent of any holder of Bonds of the 1999 Medium Term Note Series to modify the restrictions on and procedures for resale and other transfers of the Bonds of the 1999 Medium Term Note Series to reflect any change in applicable law or regulation (or the interpretation thereof) or provide alternative procedures in compliance with applicable law and practices relating to the resale or other transfer of restricted securities generally. Each holder of any bond of the 1999 Medium Term Note Series will be deemed, by the acceptance of such bond, to have agreed to any such amendment or supplement. The Company agrees to make available to any holder of Bonds of the 1999 Medium Term Note Series or a prospective purchaser of Bonds of the 1999 Medium Term Note Series, each of whom is a Qualified Institutional Buyer as defined in Rule 144A of the Securities Act of 1933, as amended, such information required by Rule 144A to enable resales of the Bonds of the 1999 Medium Term Note Series to be made pursuant to Rule 144A. However, the Company shall not be required to provide more information than was required by Rule 144A as originally adopted but may elect to do so, if necessary, under subsequent revisions of Rule 144A. This Bond shall not be entitled to any benefit under the Indenture or any indenture supplemental thereto, or become valid or obligatory for any purpose, until Chase Manhattan Trust Company, National Association, as Trustee under the Indenture, or a successor trustee thereunder, shall have signed the certificate of authentication endorsed hereon. This Bonds of the 1999 Medium Term Note Series shall be deemed to be a contract and shall be construed in accordance with and governed by the laws of the Commonwealth of Pennsylvania (excluding laws governing conflicts of law). 15 IN WITNESS WHEREOF, Philadelphia Suburban Water Company has caused this bond to be signed by its President or a Vice President and its corporate seal to be hereto affixed and attested by its Secretary or an Assistant Secretary, and this bond to be dated ____________.

There shall be a thirty-ninth series (and later series as described herein) of bonds, limited in aggregate principal amount to $300,000,000 designated as "Philadelphia Suburban Water Company First Mortgage Bonds, 1999 Medium Term Note Series, Subseries "__" (the "Bonds"). The Bonds may be issued at any time during the Offering Period in a single subseries or from time to time during the Offering Period in more than one subseries pursuant to this Thirty-Third Supplemental Indenture and the Original Indenture. Each subseries of the Bonds issued hereunder shall constitute a separate series for purposes of this Thirty-Third Supplemental Indenture and the Original Indenture. Each subseries of the Bonds shall be initially authenticated and delivered from time to time upon delivery to the Trustee of the items specified in Article IV of the Original Indenture, including the initial authorizing resolution of the Board of Directors of the Company for the issuance of the Bonds (a "Series Authorizing Resolution") and a certificate of an authorized officer of the Company issued pursuant to said resolution (a "Subseries Authorizing Certificate") specifying the principal amount of the Bonds of such subseries to be issued on the specified date of issuance, the numbers, denominations, redemption date or dates, tender date if any, maturity date or dates, redemption prices and interest rate or rates of such Bonds. Interest on each subseries of the Bonds shall be payable semiannually on January 1 and July 1 (each an "Interest Payment Date") in each year commencing on the first Interest Payment Date next succeeding the date of authentication of such Bond (the "Original Issue Date"), unless the Original Issue Date or the date of authentication occurs between a Record Date, as defined below, and the next succeeding Interest Payment Date, in which case commencing on the second Interest Payment Date succeeding the Original Issue 21 Date or the date of authentication, to the registered holders of the Bonds on the Record Date with respect to such Interest Payment Date, and on the maturity date specified on the face of the Bond (the "Maturity Date") or any date fixed for tender or redemption pursuant to the terms of such Bond (the "Tender Date" or "Redemption Date" respectively). Interest on each subseries of Bonds will accrue from the most recent Interest Payment Date to which interest has been paid or duly provided for or, if no interest has been paid, from its Original Issue Date, until the principal has been paid or made duly available for payment. If the Maturity Date (or any Redemption Date or Tender Date) or an Interest Payment Date falls on a day which is not a Business Day, as defined below, principal (and premium, if any) or interest payable with respect to such Maturity Date (or Redemption Date or Tender Date) or Interest Payment Date will be paid on the next succeeding Business Day with the same force and effect as if made on such Maturity Date (or Redemption Date or Tender Date) or Interest Payment Date, as the case may be, and no interest shall accrue with respect to such payment for the period from and after such Maturity Date (or Redemption Date or Tender Date) or Interest Payment Date. The term "Record Date" as used in this Section 1 with respect to any regular Interest Payment Date shall mean the 15th day of the calendar month preceding such Interest Payment Date. As used herein, "Business Day" means any day other than a Saturday or Sunday, on which the Trustee, any paying agent or banks in New York, New York are not required or authorized by law or executive order to close. Each subseries of the Bonds shall be stated to mature (subject to the right of earlier redemption or Tender at the prices and dates and upon the terms and conditions hereinafter set forth) and shall bear interest at the rates set forth in the Subseries Authorizing Certificate.

The Redemption Price shall initially be the Initial Redemption Percentage specified on the face of such subseries of the Bonds of the principal amount of such subseries and, if applicable, shall decline on each anniversary of the Initial Redemption Date by the Annual Redemption Reduction Percentage specified on the face of such Subseries of the Bonds, of the principal amount to be redeemed until the Redemption Price is 100% of such principal amount. SECTION 3. Each subseries of 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.

Each subseries of the Bonds may 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 or other instruments or all of the foregoing required to be delivered upon the issue of bonds pursuant to the provisions of the Original Indenture and receipt of a Series Authorizing Resolution for such subseries. SECTION 6.

By delivery of the Tender Notice, the owner irrevocably agrees to deliver the bond or bonds described therein (if such bonds are in certificated form) to the delivery office of the Trustee designated in Article V, Section 2 hereof at least five (5) Business Days prior to the Tender Date. The determination by the Trustee of a bondholder's compliance with the requirement of the Tender Notice is in its sole discretion and binding on the Company and the holder of the bond or bonds. Any Tender Notice which is determined not to be in compliance with this Thirty-Third Supplemental Indenture shall be of no force and effect. If a holder who gives a Tender Notice shall fail to deliver the bond identified in the Tender Notice to the Trustee at or prior to 10:00 a.m. on the Purchase Date, such bond shall be deemed purchased and shall cease to accrue interest on such Tender Date and the holder thereof shall thereafter be entitled only to payment of the Tender Price therefor and to no other benefits of this Thirty-Third Supplemental Indenture. Notwithstanding anything to the contrary herein, the right of the holders of a bond to tender the bonds shall cease immediately and without further notice from and including the date on which the Trustee notifies the holder of such bond of an acceleration under Article XI of the Indenture. 24 ARTICLE II.
