Section 1. Background.

(a) The Authority proposes to enter into a Financing Agreement (the “Financing Agreement”) dated as of October 15, 2010 with the Company, under which the Authority will agree to loan to the Company funds: (i) to currently refund on November 18, 2010 (the “Refunding Project”) the outstanding $25,000,000 Delaware County Industrial Development Authority Water Facilities Revenue Bonds (Philadelphia Suburban Water Company Project), Series of 1999 (the “1999 Bonds”), which were issued to finance the costs of the facilities located at various sites throughout the Company’s existing water supply and distribution system, and to pay a portion of the costs of issuance of such bonds (the “1999 Project Facilities”); and the outstanding $18,360,000 Mercer County Industrial Development Authority Water Facilities Revenue Bonds, Series of 2000 (Consumers Pennsylvania Water Company – Shenango Valley Division Project) (the “2000 Bonds”, and together with the 1999 Bonds, the “Prior Bonds”), which were used to finance a portion of the cost of acquisition, construction, installation and equipping of its water treatment and filtration facilities located in Sharon, Pennsylvania, and pay a portion of the costs of issuance of such bonds (the “2000 Project Facilities”, and together with the 1999 Project Facilities, the “Refunding Project Facilities”), and related refunding financing costs; (ii) to finance certain capital costs of the construction, acquisition and installation of modifications, expansions and replacements of water distribution, treatment and related operating systems located in the counties of Bucks, Chester, Delaware, Mercer, Montgomery and Warren Counties in Pennsylvania (the “Project Facilities” and together with the Refunding Project Facilities the “Facilities”) that are part of the Company’s System (the “Construction Project”, and together with the “Refunding Project”, the “Project”); and (iii) the related financing costs.

To finance the loan under the Financing Agreement, the Authority proposes to issue and sell $45,180,000 aggregate principal amount of its Water Facilities Revenue Refunding Bonds (Aqua Pennsylvania, Inc. Project), Series A of 2010 (the “2010A Bonds”), and $96,205,000 aggregate principal amount of its Water Facilities Revenue Bonds (Aqua Pennsylvania, Inc. Project), Series B of 2010 (the “2010B Bonds”, and together with the 2010A Bonds, the “Bonds”) to the Underwriters, who will in turn reoffer the Bonds for sale to the public.

(b) The Bonds will be issued pursuant to the Pennsylvania Economic Development Financing Law, Act of August 23, 1967, P.L. 251, as amended and supplemented (the “Act”), a resolution adopted by the Authority on September 15, 2010 (the “Authority Resolution”) and a Trust Indenture, dated as of October 15, 2010 (the “Trust Indenture”), between the Authority and U.S. Bank National Association, as trustee (the “Trustee”). The Bonds will have such terms as are set forth in Schedule II attached hereto.

The Bonds will be payable out of payments by the Company under the Financing Agreement, including payments under its First Mortgage Bond, 5.00% Series due December 1, 2033 in the principal amount of $25,910,000; its First Mortgage Bond, 5.00% Series due December 1, 2034, in the principal amount of $19,270,000; its First Mortgage Bond, 4.50% Series due December 1, 2042, in the principal amount of $15,000,000; and its First Mortgage Bond, 5.00% Series due December 1, 2043, in the principal amount of $81,205,000 (together, the “First Mortgage Bonds”) issued with respect to the Bonds. The First Mortgage Bonds will be issued under and secured by the Company’s Indenture of Mortgage dated as of January 1, 1941 (the “Indenture of Mortgage”), from the Company to The Bank of New York Mellon Trust Company, N.A., as trustee (successor to The Pennsylvania Company for Insurance on Lives and Granting Annuities, The Pennsylvania Company for Banking and Trusts, The First Pennsylvania Banking and Trust Company, First Pennsylvania Bank, N.A., CoreStates Bank, N.A., Mellon Bank, N.A., Chase Manhattan Trust Company, National Association and J.P. Morgan Trust Company, National Association) (the “Mortgage Trustee”), as presently amended and supplemented and as to be further supplemented by a Forty-sixth Supplemental Indenture of Mortgage to be dated as of October 15, 2010 (the “Forty-sixth Supplemental Mortgage”, which together with the Indenture of Mortgage, as amended and supplemented, is referred to hereinafter as the “Mortgage”). Each of the First Mortgage Bonds will be issued in the same aggregate principal amount, and will mature on the same date and bear interest at the same rate as the Bonds that it secures. All of the Authority’s rights under the Financing Agreement to receive and enforce repayment of its loan to the Company and to enforce payment of the Bonds, including all of the Authority’s rights to the First Mortgage Bonds, and all of the Authority’s rights to moneys and securities in the Project Funds, the Revenue Funds and the Debt Service Funds (and the accounts within all such Funds applicable to the Bonds) established by the Trust Indenture, except for the Authority’s rights to certain fees and reimbursements for expenses, indemnification and notice thereunder and rights relating to amendments of and notices under the Financing Agreement, will be assigned to the Trustee as security for the Bonds pursuant to the Trust Indenture.

(c) The proceeds of the 2010A Bonds and 2010B Bonds will be used to refinance and finance, respectively, the acquisition, construction, installation and equipping of facilities for the furnishing of water for purposes of Section 142(a)(4) of the Internal Revenue Code of 1986, as amended (the “Code”), so that the interest on the Bonds will not be includable in gross income for federal income tax purposes under the Code and the Underwriters may offer the Bonds for sale without registration under the Securities Act of 1933, as amended (the “1933 Act”), or qualification of the Trust Indenture under the Trust Indenture Act of 1939, as amended (the “1939 Act”).

(d) A Preliminary Official Statement dated October 15, 2010, including the Appendices thereto and all documents incorporated therein by reference (the “Preliminary Official Statement”), has been supplied to the parties hereto, and a final Official Statement to be dated the date hereof, including the Appendices thereto and all documents incorporated therein by reference, prepared for use in such offerings will be supplied to the parties hereto as soon as it is available, subject to Section 10 hereof (such final Official Statement, as it may be amended or supplemented with the consent of the Authority, the Representative and the Company, is hereinafter referred to as the “Official Statement”).

Section 2. Purchase, Sale and Closing. On the terms and conditions herein set forth, the Underwriters will buy from the Authority, and the Authority will sell to the Underwriters, all (but not less than all) of the Bonds at a purchase price equal to $141,764,215.45, which is equal to the $141,385,000.00 aggregate principal amount of the Bonds, plus net original issue premium of $1,838,245.45, less the underwriting discount of $1,459,030.00. Payment for the Bonds shall be made in immediately available funds to the Trustee for the account of the Authority. Closing (the “Closing”) will be at the offices of Ballard Spahr LLP, Philadelphia, Pennsylvania (“Bond Counsel”), at 10:00 a.m., Eastern Standard Time, on November 17, 2010 or at such other date, time or place or in such other manner as may be agreed on by the parties hereto.

(k) The Project consists of either land or property of a character subject to depreciation for federal income tax purposes and will be used to furnish water that is or will be made available to members of the general public (including electric utility, industrial, agricultural, or commercial users); the rates for the furnishing or sale of the water have been established or approved by a state or political subdivision thereof, by an agency or instrumentality of the United States, or by a public service or public utility commission or other similar body of any state or political subdivision thereof; and all other information supplied by the Company to the Representative with respect to the exclusion from gross income pursuant to Section 103 of the Code of the interest on the Bonds is correct and complete.

Section 5. Authority’s Covenants. The Authority will:

(a) Furnish such information, execute such instruments and take such other action in cooperation with the Representative as the Representative may reasonably request to qualify the Bonds for offer and sale under the Blue Sky or other securities laws and regulations of such states and other jurisdictions in the United States of America as the Representative may designate and will assist, if necessary therefor, in the continuance of such qualifications in effect so long as required for distribution of the Bonds; provided, however, that the Authority shall in no event be required to file a general consent to suit or service of process or to qualify as a foreign corporation or as a dealer in securities in any such state or other jurisdiction.

(c) Refrain from knowingly taking any action (and permitting any action with regard to which the Authority may exercise control) that would result in the loss of the exclusion from gross income for federal income tax purposes of interest on the Bonds.

Section 6. Company’s Covenants. The Company agrees that it will:

(a) Refrain from knowingly taking any actions (and from permitting any action with regard to which the Company may exercise control) that would result in the loss of the exclusion from gross income for federal tax purposes of interest on the Bonds.

(b) Indemnify and hold harmless the Authority, its members, directors, officers, agents, attorneys, and employees and the Underwriters, their respective officers, directors, officials, agents, attorneys, employees, and each person, if any, who controls each of the Underwriters within the meaning of Section 15 of the 1933 Act or Section 20 of the Securities Exchange Act of 1934, as amended (the “1934 Act”), from and against all losses, claims, damages, liabilities and expenses, joint or several, to which the Authority and the Underwriters, or either of them, or any of their respective members, directors, officers, agents, attorneys, and employees and each person, if any, who controls the Underwriters within the meaning of the 1933 Act or 1934 Act as aforedescribed may become subject, under federal laws or regulations, or otherwise, insofar as such losses, claims, damages, liabilities and expenses (or actions in respect thereof) arise out of or are based upon: (i) a breach of the Company’s representations included in this Agreement; (ii) any untrue statement or alleged untrue statement of any material fact pertaining to the Project or the Company set forth in the Official Statement, the Preliminary Official Statement or any amendment to either; (iii) the willful or negligent omission of (or the alleged omission to state) a material fact in the Official Statement, the Preliminary Official Statement, or any amendment or supplement to either, as such fact is required to be stated therein or necessary to make the statements therein that pertain to the Company or the Project not misleading in the light of the circumstances under which they were made; (iv) or arising by virtue of the failure to register the Bonds under the 1933 Act or the failure to qualify the Trust Indenture under the 1939 Act; or (v) arising by virtue of any audit or investigation conducted by a state or federal agency, department or entity questioning, among other things, the tax-exempt status of the Bonds.

(c) Undertake, pursuant to the Continuing Disclosure Agreement dated as of November 17, 2010 to be entered into between the Company and the Trustee (the “Continuing Disclosure Agreement”), to provide annual reports and notices of certain material events in accordance with Rule l5c2-l2 under the 1934 Act, as amended (“Rule 15c2-12”).

(d) Not amend or supplement the Official Statement without prior notice to, and the consent of, the Representative, and will advise the Representative and the Authority promptly of the institution of any proceedings by any governmental agency or otherwise affecting the use of the Official Statement in connection with the offer and the sale of the Bonds.

Section 7. Underwriters’ Covenant and Compensation.

(a) By acceptance hereof, each of the Underwriters, on a several (according to their respective percentages on Schedule I) but not joint basis, agrees to indemnify and hold harmless the Authority, its members, directors, officers, agents, attorneys, and employees and the Company, its officers, directors, agents, attorneys, and employees and each person if any, who controls the Company within the meaning of Section 15 of the 1933 Act against all or several claims, losses, damages, liabilities and expenses asserted against them, or any of them, at law or in equity, in connection with the offering and sale of the Bonds on the grounds that the information under the caption “UNDERWRITING” in the Preliminary Official Statement or the Official Statement (or any supplement or amendment to said information) contains an untrue or allegedly untrue statement of a material fact or omits or allegedly omits to state any material fact necessary to make the statements therein not misleading in the light of the circumstances under which they were made (it being understood that the Underwriters furnished only the information under such “UNDERWRITING” heading), or failure on the part of the Underwriters to deliver an Official Statement to any purchaser. The Underwriters will reimburse any legal or other expenses reasonably incurred by a party, person or entity indemnifiable under this Section 7 in connection with investigating or defending any such loss, claim, damage, liability or action. This indemnity agreement will be in addition to any liability that the Underwriters may otherwise have. The Underwriters shall not be liable for any settlement of, any such action effected without its consent.

(b) The Underwriters will be paid an underwriting discount of $1,459,030.00 with respect to the Bonds.

(c) The Underwriters acknowledge that the Authority is relying upon the accuracy of the certification in clause (b) above on the date hereof as a condition precedent to lending the proceeds of the Bonds to the Company.

Section 8. Notice of Indemnification; Settlement. Promptly after a party, person or entity indemnifiable under Section 6 or 7 of this Bond Purchase Agreement (an “Indemnitee”) receives notice of the commencement of any audit, investigation or action against such Indemnitee in respect of which indemnity is to be sought by the Indemnitee against the Company or any of the respective Underwriters, as the case may be (the “Indemnifying Party”), the Indemnitee will notify the Indemnifying Party in writing of such action, and the Indemnifying Party may assume the defense thereof, including the employment of counsel and the payment of all expenses; but the failure so to notify the Indemnifying Party will not relieve the Indemnifying Party from any liability that it may have to the Indemnitee otherwise than hereunder. The Indemnifying Party shall not be liable for any settlement of any such action effected without its consent, but if settled with the consent of the Indemnifying Party or if there is a final judgment for the plaintiff in any such action, the Indemnifying Party will indemnify and hold harmless the Indemnitee from and against any loss or liability by reason of

such settlement or judgment. The indemnity agreements contained in this Bond Purchase Agreement shall include reimbursement for expenses reasonably incurred by an Indemnitee in investigating the claim and in defending it if the Indemnifying Party declines to assume the defense and shall survive delivery of the Bonds. Notwithstanding the foregoing, in the event of an investigation or audit by the Internal Revenue Service or the Securities and Exchange Commission or any other state or federal agency, department, or entity with respect to the Bonds, the Authority shall have the right and duty to undertake its own defense, including the employment of counsel, with full power to litigate, compromise or settle the same on its own behalf, and the Company agrees that it will indemnify and hold the Authority harness for all costs and expenses, including, but not limited to, attorney fees and expenses and costs, of any such settlement.

Section 9. Equitable Contribution. If the indemnification provided for in Section 6(b) of this Bond Purchase Agreement is unavailable to any of the respective Underwriters (or any controlling person thereof) in respect of any losses, claims, damages or liabilities referred to therein, then the Company shall, in lieu of indemnifying each or any of the respective Underwriters, contribute to the amount paid or payable by each or any of the Underwriters as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative benefits received by the Company and the Underwriters, respectively, from the offering of the Bonds. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then the Company shall contribute to such amount paid or payable by the Underwriters in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and each or any of the Underwriters, respectively, in connection with the statements or omission which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefit received by the Company or the Underwriters shall be deemed to be in the same proportion as the total proceeds from the offering (before deducting issuance costs and expenses other than underwriting fees and commissions) received by the Company, on the one hand, bear to the total Underwriting fees and commissions received by the Underwriters, on the other hand. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact related to information supplied by the Company or each of the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to above in this Section 9. The amount paid or payable by each of the Underwriters as a result of the losses, claims, damages or liabilities referred to above in this Section 9 shall be deemed to include any reasonable legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the amount of the discount allowed to each Underwriter as set forth in Section 7(b) hereof.

Section 10. Official Statement; Public Offering.

(a) In order to enable the Underwriters to comply with Rule l5c2-l2, the Company has prepared (or caused to be prepared) the Preliminary Official Statement, which the Company and the Authority (in the case of the Authority, only with respect to the information therein under the headings “THE AUTHORITY” and, insofar as they relate to the Authority, “INTRODUCTORY STATEMENT” and “ABSENCE OF MATERIAL LITIGATION”) deem final and complete as of its date except for certain permitted omissions as described in Rule l5c2-l2. The Company shall provide to the Representative sufficient copies of the Official Statement in sufficient time to accompany any confirmation that requires payment from any customer and in any event within seven (7) business days after the date of this Bond Purchase Agreement. If the Company, during the period described in Section l0(b) below, has or gains knowledge of a fact or circumstance that would render the Official Statement misleading in any material respect, then the Company shall promptly give the Representative written notice thereof.

The Authority shall cooperate with the Company in the issuance and distribution of any such amendment or supplement.

(c) Upon Closing, the Representative shall promptly provide the Municipal Securities Rulemaking Board with a copy of the Official Statement for filing in accordance with Rule 15c2-l2, and inform the Authority and the Company in writing as to the date and place of such filing and the date of the end of the underwriting period.

(d) Any event or condition occurring or arising after the date hereof, which in the reasonable judgment of the Representative renders untrue or incorrect, in any material respect as of the time to which the same purports to relate, the information contained in the Official Statement, or which requires that information not reflected in the Official Statement or Appendices thereto should be reflected therein in order to make the statements and information contained therein not misleading in any material respect as of such time; provided that the Authority, the Company and the Representative will use their best efforts to amend or supplement the Official Statement to reflect, to the reasonable satisfaction of the Representative, such changes in or additions to the information contained in the Official Statement.
