Exhibit 10.24 PHILADELPHIA SUBURBAN CORPORATION DEFERRED COMPENSATION PLAN MASTER TRUST AGREEMENT THIS TRUST AGREEMENT is made and entered into as of this 31st day of December, 1996 by and between Philadelphia Suburban Corporation, a corporation organized and existing under the laws of the Commonwealth of Pennsylvania (the "Company"), and PNC Bank, National Association, a banking association organized and existing under the laws of the Commonwealth of Pennsylvania (the "Trustee"). WITNESSETH: WHEREAS, the Company and each Affiliated Company which is designated by the Board of Directors as a Participating Employer have established or may hereafter establish certain non-qualified employee benefit plans and programs (hereinafter referred to collectively as the "Plans"), listed on Exhibit A attached hereto as of the date hereof or, thereafter, added if designated by the President of the Company (the "President"); and WHEREAS, the Plans provide for the Company to pay all benefits from its general revenues and assets; WHEREAS, the Company wishes to establish separate irrevocable trust funds (individually, a "Trust" and collectively, the "Trusts") with respect to designated participants in the Plans, though, prior to a Change of Control, as defined in Section 16.3 hereof, any such Trust may not necessarily hold sufficient assets to satisfy all of the benefits to be provided under the Plans; WHEREAS, the Company also wishes to establish a Trust fund to provide a source for payment of any fees, including legal fees, incurred by the Trustee in the administration of the Trusts or by participants in enforcing their rights hereunder (the "Fee Trust") and a Trust fund to provide a source of payment of any benefits under a Plan to the extent that the assets of an individual Trust established for a Participant are insufficient to provide all benefits due (the "Shortfall Trust"); WHEREAS, the Company wishes to contribute to the Trusts assets, either on the date hereof or thereafter as determined by the President, that shall be held therein, to serve as a source of funds to assist it in meeting its liabilities under the Plans, subject to the claims of Company's creditors in the event of Company's Insolvency, as herein defined, until paid to Plan participants and their beneficiaries in such manner and at such times as specified hereunder or in the Plans; WHEREAS, contributions to the Trusts shall be held by the Trustee and invested, reinvested and distributed in accordance with the provisions of this Trust Agreement; WHEREAS, each Trust established by this Trust Agreement is intended to be a "grantor trust" with the result that the corpus and income of the Trusts are treated as assets and income of the Company pursuant to Sections 671 through 679 of the Internal Revenue Code of 1986, as amended (the "Code"); WHEREAS, the Company has appointed the Pension Committee of the Board of Directors (the "Committee"), to administer the Trusts established hereunder and otherwise to act on behalf of the Company in a non-fiduciary capacity. -1- NOW, THEREFORE, the parties do hereby establish the Trusts and agree that the Trusts shall be comprised, held and disposed of as follows: ARTICLE I ESTABLISHMENT 1.1 The Company hereby establishes with the Trustee a separate, and subject to Section 16.2 hereof, irrevocable Trust on behalf of each participant in the Plans designated by the Committee (the "Participant") pursuant to a separate agreement or agreements that shall be expressly incorporated in and made a part of this Trust Agreement (each such agreement to be attached hereto as part of Exhibit B) as well as the Shortfall Trust. Each separate Trust shall be governed by the terms of this Trust Agreement. Each Trust is intended to be exempt from substantially all of the provisions of the Employee Retirement Income Security Act of 1974, as amended, ("ERISA") by reason of the provisions of Sections 201(2), 301(3) and 401(1) thereof, as applicable, and the Company shall immediately notify the Trustee should such exempt status change for any reason. 1.2 The Trust shall consist of such sums of money and other property acceptable to the Trustee as shall be paid or delivered to the Trustee by the Company immediately following the date hereof or from time to time in the future, as determined by the President. The Fee Trust and the Shortfall Trust shall be irrevocable and each other Trust, subject to the provisions of Section 16.2 hereof, shall be irrevocable for the Participant for which it is established. Except as provided in Sections 4.2, 4.3 and 16.2 hereof, the Company shall have no right to direct the Trustee to return or divert any Trust assets before the payment of all benefits under the Plans to the Participant. All such money and other property, all in vestments and reinvestment made therewith or proceeds thereof and all earnings and profits (less losses) thereon, less all payments and charges as authorized herein, for each of the Trusts are hereinafter referred to as the "Trust Fund". The Trust Fund shall be held by the Trustee and shall be dealt with in accordance with the provisions of this Trust Agreement. All Trust Funds created hereunder shall be treated as a single trust fund for purposes of investing the assets of each Trust Fund (the "Fund") but the Trustee shall maintain, or cause to be maintained records sufficient to determine the interest of each Trust Fund in the Fund. 1.3 Within 90 days of the date hereof, the Company shall fund each Trust Fund (other than the Fee Trust) with sufficient assets to provide the benefits due, through December 31, 1995, to the Participant for whose benefit the Trust Fund has been established. Thereafter, and subject to the provisions of Article XVI, the Company may contribute such sums of money or property to the Trust Fund, from time to time, as the President determines appropriate, in the President's sole discretion, without any requirement that the amount of such contributions be sufficient to meet the minimum funding standards imposed by ERISA which are not applicable to contributions under the Plans. 1.4 The principal of each Trust Fund and the Fund, and any earnings thereon shall be held separate and apart from other funds of Company and shall be used exclusively for the uses and purposes of Participants and general creditors as herein set forth. Participants and their beneficiaries shall have no preferred claim on, or any beneficial ownership interest in, any assets of the Trust Fund. Any rights created under the Plans and this Trust Agreement shall be mere unsecured contractual rights of Participants and their beneficiaries against the Company. Any assets held by the Fund will be subject to the claims of the Company's general creditors under federal and state law in the event of Insolvency, as defined in Section 4.2 herein. -2- ARTICLE II TRUSTEE ACCEPTANCE 2.1 The Trustee accepts each Trust established under this Trust Agreement on the terms and subject to the provisions set forth herein, and it agrees to discharge and perform fully and faithfully all of the duties and obligations imposed upon it under this Trust Agreement. 2.2 The Trustee shall not be responsible for the proper operation of the Plans. ARTICLE III PLANS IN RELATION TO TRUST AGREEMENT 3.1 A copy of each of the Plans is attached hereto as Exhibit C. All defined terms used herein and not defined shall have the respective meanings set forth in the Plans unless specifically provided to the contrary herein. The Company will promptly deliver to the Trustee copies of all amendments to the Plans and copies of any additional plans to be covered by this Agreement after the date first above written. 3.2 The terms of each of the Plans shall govern the amount, form and timing of benefit payments under each Plan to which a Participant is entitled. 3.3 The provisions of this Trust Agreement shall not cause the Plans to become irrevocable under the provisions of Section 1.2 of this Trust Agreement. 3.4 The Trustee shall not be a party to the Plans, nor shall the Trustee have any right or obligations with respect to any of the provisions of the Plans relating to the funding of benefits or the funding of the Fee Trust or the Shortfall Trust. ARTICLE IV TRUST FUND 4.1 It is intended that each Trust constitute a grantor trust under Code Sections 671 through 679, with the assets of the Fund being treated as assets of the Company for purposes of Federal, state and local income tax laws. The creation of the Trusts shall not cause the Plans to be treated as funded plans for purposes of Title I of the Employee Retirement Income Security Act of 1974, as amended from time to time. 4.2. The assets of the Fund shall at all times be subject to the claims of the general creditors of the Company under Federal and state law. The Trustee shall suspend payments to the Participants from the Fund if the Trustee receives timely written notification from the Company's Board of Directors and its Chief Executive Officer that the Company is Insolvent. For purposes of this Article IV, the term "Insolvent" means (a) the inability of the Company to pay its debts when they mature or (b) the Company is subject as a debtor to a pending proceeding under the Federal Bankruptcy Code. It shall be the duty of the Company's Board of Directors and its Chief Executive Officer to provide the Trustee with timely written notification of such events. Under any such circumstance, the Trustee shall suspend payments from the Fund to the Participants and shall pay the assets held in the Fund only as a court of competent jurisdiction shall direct to satisfy claims of general creditors of the Company. It is intended that the rights of the general creditors of the Company to enforce the provisions of this Article in the event of the Company's Insolvency be enforceable with respect to the Fund at the time of Insolvency under both Federal and state law. It is also intended that no provision of this Trust Agreement shall in any way affect the Participants' rights as general creditors of the Company. -3- 4.3 If a person claiming to be a creditor of the Company alleges in writing to the Trustee that the Company has become Insolvent, the Trustee shall determine whether the Company is Insolvent and, pending such determination, in accordance with Section 4.4, the Trustee shall discontinue payment of benefits to Participants or beneficiaries. 4.4 Unless the Trustee has actual knowledge of the Company's Insolvency, or has received notice from the Company or a person claiming to be a creditor alleging that the Company is Insolvent, the Trustee shall have no duty to inquire whether the Company is Insolvent. The Trustee may in all events rely on such evidence concerning the Company's Insolvency as may be furnished to the Trustee and that provides the Trustee with a reasonable basis for making a determination concerning the Company's Insolvency. 4.5 The Trustee shall resume the payment of benefits to the Participants or beneficiaries in accordance with Article VII of this Trust Agreement only after the Trustee has determined that the Company is not Insolvent (or is no longer Insolvent) based on such evidence as the Trustee determines to be sufficient for such purpose such as a report from the Company's independent auditors, if the Company is not subject to a bankruptcy proceeding or otherwise an order from a court of competent jurisdiction. 4.6 Provided that there are sufficient assets, if the Trustee discontinues the payment of benefits from the Fund pursuant to this Article and subsequently resumes such payments, the first payment following such discontinuance shall include the aggregate amount of all payments due to the Participants or beneficiaries under the terms of the Plans for the period of such discontinuance, less the aggregate amount of any payments made to the Participants or beneficiaries by the Company in lieu of the payments provided for hereunder during any such period of discontinuance. ARTICLE V DUTIES OF THE TRUSTEE WITH RESPECT TO INVESTMENTS AND DIRECTIONS 5.1 The Trustee shall invest and reinvest the principal and income of the Trust Fund as directed by the Committee in writing, which directions may be changed from time to time. Following the receipt of notice of a Change of Control pursuant to Section 16.1 hereof, the Trustee shall invest and reinvest the principal and income of the Trust Fund as it shall determine in its sole discretion subject to the overall objective of the Fund which is the preservation of capital. In such event, the Trustee shall keep the Trust Fund invested, without distinction between principal and income, in any property, whether real, personal or mixed, and wherever situated and whether or not productive of income, including without limitation, capital, common and preferred stocks, and personal, corporate and governmental or other obligations, whether secured or unsecured, and including any collective part interest therein; trust and participation certificates or other evidences of ownership, part ownership or part interest; all without being limited or restricted to investments of a character authorized for trustees or other fiduciaries under any present or future laws and, except as otherwise required by Federal law without regard to the proportion any such property may bear to the entire amount of the Trust Fund. Specifically, but not by way of limitation, the Trustee is authorized and empowered to invest all or any part of the Trust Fund in any common or collective trust fund or pooled investment fund presently or hereafter maintained by the Trustee as the same may be amended from time to time; and the declaration of trust establishing such common or collective fund is hereby made a part hereof as if set forth at length herein, the assets of the fund invested in said common or collective trusts shall be held and administered by the Trustee strictly in accordance with the terms of the instrument, and the combining of assets of the Trust Fund with assets of other trusts in such common or collective trust fund is specifically authorized hereby. -4- 5.2 The Trustee shall not be liable for any loss or any breach which arises from the Committee's exercise or non-exercise of rights under this Article 5, unless it was clear on their face that the actions to be taken under the Committee's directions were contrary to the terms of this Agreement. 5.3 Whenever the President or the Committee provides a direction to the Trustee, the Trustee shall not be liable for any loss, or by reason of any breach, arising from the direction (i) if the direction is contained in a writing (or is oral and immediately confirmed in a writing) signed by any individual whose name and signature have been submitted (and not withdrawn) in writing to the Trustee by the President and (ii) if the Trustee reasonably believes the signature of the individual to be genuine, unless it is clear on the directions face that the actions to be taken under the direction would be contrary to the terms of this Agreement or applicable law. 5.4 The Company shall indemnify the Trustee against, and hold the Trustee harmless from, any and all loss, damage, penalty, liability, cost and expense, including without limitation, reasonable attorneys' fees and disbursements, that may be incurred by, imposed upon, or asserted against the Trustee by (i) reason of any claim, regulatory proceeding, or litigation arising from any act done or omitted to be done by any individual or person with respect to any Plan or the Trust, (ii) any action incident to a good faith determination concerning the Company's Insolvency or (iii) following the advice of counsel in good faith, excepting, in any such case, only any and all loss, etc., arising solely from the Trustee's negligence, bad faith or breach of applicable law or the terms of this Agreement. Notwithstanding the foregoing, the Company shall not indemnify the Trustee, unless the Trustee gives reasonably prompt written notice to the Company of any such claim, regulatory proceeding or litigation and offers the Company the right to defend against any such action unless the positions of the Company and the Trustee are in conflict and in any event the Trustee shall have the right to consult as to the defense. 5.5 The provisions of this Article V shall survive the termination of this Agreement. ARTICLE VI ADDITIONAL POWERS AND DUTIES OF THE TRUSTEE 6.1 Subject to the provisions of Article V hereof, the Trustee shall have the following powers and authority with respect to all property constituting part of the Fund: (a) To sell, exchange, convey or transfer any property at public or private sale for cash or on credit and grant options for the purchase or exchange thereof; provided, however, that in no event may the Trustee invest in securities (including stock or rights to acquire stock unless such stock is the Company's principal class of common stock) or obligations issued by the Company, other than a de minimis amount held in common investment vehicles in which the Trustee invests. No person dealing with the Trustee shall be bound to see to the application of the purchase money or other property delivered to the Trustee or to inquire into the validity, expedience or propriety of any such sale or other disposition. (b) To participate in any plan of reorganization, consolidation, merger, combination, liquidation or other similar plan relating to any such property, and to consent to or oppose any such plan or any action thereunder, or any contract, lease, mortgage, purchase, sale or other action by any corporation or other entity.

ARTICLE VII PAYMENTS BY THE TRUSTEE 7.1 If a Participant or beneficiary does not receive a payment(s) from the Company to which the individual claims entitlement under any of the Plans, the individual shall notify the Company, or, in the case of a Change of Control, the Trustee, in writing of such entitlement. 7.2 The Trustee shall make payments to a Participant or beneficiary in accordance with written instructions given at the time of payment or in advance of such payment to the Trustee from the President as to the manner and timing of payments hereunder and the Trustee shall have no responsibility to determine the amount of such payments. Any such instructions in effect on the date of this Trust Agreement shall be attached hereto as Exhibit D, as the same may be changed from time to time prior to a Change of Control. The Company may not change such instructions on or after notification or knowledge of a Change of Control of the Company with respect to benefits accrued to date. 7.3 Nothing in this Trust Agreement shall be deemed to limit the rights of a Participant (or beneficiary) under the Plans, including the right to contest the denial of benefit payment(s) and, following a Change of Control, to have all reasonable legal fees and expenses incurred in contesting a denial paid from the Fee Trust. 7.4 The Trustee shall withhold from each payment any Federal withholding taxes or charges which the Trustee is properly instructed to deduct by the President or, following a Change of Control, by any compensation consultant engaged by the Company as to which the Trustee is notified in the instructions referred to in Section 7.2 hereof, and remit the amount withheld to the Company for deposit and reporting of such amounts to the appropriate authorities. 7.5 The insufficiency of assets in the Trust Fund shall not relieve the Company of its obligations or liabilities to make benefit payments otherwise due to a Participant or beneficiary under the terms of the Plans. 7.6 If any portion of the Trust Fund has been invested in a life insurance contract, the Trustee shall be precluded from payment of any benefits it has received pursuant to that contract to the Company unless the Participant (or beneficiary) has received all benefit payments due and payable under the terms of the applicable Plan. 7.7 The Company may make payment of benefits directly to Participants or their beneficiaries as they become due under the terms of the Plans. The Company shall notify the Trustee of its decision to make payment of benefits directly prior to the time amounts are payable to Participants or their beneficiaries. In addition, if the principal of the Trust Fund is not sufficient to make payments of benefits in accordance with the terms of the Plans, the Trustee shall use assets of the Shortfall Trust to make -7- payments due but if not sufficient, the Company shall make the balance of each such payment as it falls due. The Trustee shall notify the Company where principal and earnings of the Trust and the Shortfall Trust are not sufficient. ARTICLE VIII TAXES, EXPENSES AND COMPENSATION 8.1 The Company shall from time to time pay taxes of any and all kinds which are lawfully levied or assessed upon or become payable in respect of the Trust Fund, the income or any property forming a part thereof, or any security transaction pertaining thereto. To the extent that any taxes lawfully levied or assessed upon the Trust Fund are not paid by the Company, the Trustee shall pay such taxes out of the Fee Trust, or, to the extent that the Fee Trust is insufficient, on a pro rata basis from the other Trust Funds. The Trustee shall at the expense and direction of the Company contest the validity of any taxes in any manner deemed appropriate by the Company or its counsel or the Company may itself contest the validity of any such taxes. All reasonable expenses incurred by the Trustee in the performance of its duties under this Trust Agreement, including but not limited to legal fees and brokerage commissions, shall be charged against and paid from the Fee Trust to the extent that the Company does not pay such expenses, or, to the extent that the Fee Trust is insufficient, on a pro rata basis from the other Trust Funds. 8.2 The Company will pay the Trustee such reasonable compensation for its services indicated in Fee Schedule attached hereto as Exhibit E and as may thereafter be agreed upon in writing from time to time by the Company and the Trustee. Such compensation shall be paid directly by the Company. In the event such compensation is not paid by the Company, it shall be charged against the Fee Trust. ARTICLE IX ADMINISTRATION AND RECORDS 9.1 The Trustee shall keep or cause to be kept accurate and detailed accounts of any investments, receipts, disbursements and other transactions hereunder, and all accounts, books and records relating thereto shall be open to inspection and audit at all reasonable times by any person designated by the Company. All such accounts, books and records shall be preserved (in original form, or on microfilm, magnetic tape or any other similar process) for such period as the Trustee may determine, but the Trustee may only destroy such accounts, books and records after first notifying the Company in writing of its inten tion to do so and transferring to the Company any of such accounts, books and records requested. 9.2 Within 60 days after the close of each calendar year, and within 60 days after the removal or resignation of the Trustee or of the termination of the Trust, the Trustee shall file with the Company (and provide a copy thereof to the Participants, upon a written request) a written accounting setting forth all investments, receipts, disbursements and other transactions effected by it during the preceding calendar year and, if applicable, during the current calendar year to the date of such removal, resignation or termination, including a description of all investments and securities purchased and sold with the cost or net proceeds of such purchases or sales and showing all cash, securities and other property held at the end of such calendar year or other period and the fair market value thereof. To the extent permitted by applicable law, upon the expiration of 180 days from the date of filing such annual or other accounting, the Trustee shall be released and discharged from all liability and accountability with respect to the propriety of its acts and transactions shown in such accounting, except with respect to any such acts or transactions as to which the Company shall within such 180 day period file with the Trustee written objections. -8- 9.3 Nothing contained in this Trust Agreement shall be construed as depriving the Trustee or the Company of the right to have a judicial settlement of the Trustee's accounts, and upon any proceeding for a judicial settlement of the Trustee's accounts or for instructions, the only necessary party thereto in addition to the Trustee shall be the Company. 9.4 In the event of the removal or resignation of the Trustee, the Trustee shall deliver to the successor trustee all records which shall be required by the successor trustee to enable it to carry out the provisions of this Trust Agreement. 9.5 In addition to any returns required of the Trustee by law, the Trustee shall prepare and file such tax reports and other returns as the Company and the Trustee may from time to time agree upon in writing. ARTICLE X REMOVAL OR RESIGNATION OF THE TRUSTEE AND DESIGNATION OF SUCCESSOR TRUSTEE 10.1 The Company may remove the Trustee with or without cause, upon at least 60 days' notice in writing to the Trustee; provided, however, that following a Change of Control of the Company, as defined in Article XVI hereof, the Trustee may be removed only for cause. 10.2 The Trustee may resign at any time upon at least 60 days' notice in writing to the Company. 10.3 In the event of such removal or resignation, the Trustee shall duly file with the Company a written accounting as provided in Section 9.2 hereof for the period since the last previous annual accounting, listing the investments of the Trust and any uninvested cash balance thereof, and setting forth all receipts, disbursements, distributions and other transactions respecting the Trust not included in any previous accounting, and if written objections to such accounting are not filed as provided in Section 9.2 hereof, the Trustee shall to the maximum extent permitted by applicable law be forever released and discharged from all liability and accountability with respect to the propriety of its acts and transactions shown in such accounting. 10.4 Within 60 days after any notice of removal or resignation of the Trustee, the Company shall designate a successor trustee qualified to act hereunder; provided, however that in no event may the Company, an affiliate of the Company or of any Participant serve as the successor trustee. Notwithstanding the foregoing, the Trustee may not be removed or resign following a Change of Control of the Company unless the Trustee or the Company has obtained the agreement of, or a court of competent jurisdiction has appointed, a bank with assets in excess of $1 billion and net worth in excess of $50 million (a "Replacement Trustee") to replace the Trustee as trustee under the terms of this Trust Agreement. In any event, the Trustee shall continue to be custodian of the Fund's assets until the new trustee is in place, and the Trustee shall be entitled to expenses and fees through the end of its custodianship of the Fund. Each such successor trustee, during such period as it shall act as such, shall be bound by all of the provisions hereof as well as any instructions provided by the Company pursuant to the provisions hereof, shall have the powers and duties herein conferred upon an individual trustee, and the word "Trustee" wherever used herein, except where the context otherwise requires, shall be deemed to include any successor trustee. -9- 10.5 Upon designation of a successor trustee and delivery to the resigned or removed Trustee of written acceptance by the successor trustee of such designation, such resigned or removed trustee shall promptly assign, transfer, deliver and pay over to such successor trustee, in conformity with the re quirements of applicable law, the funds and properties in its control or possession then constituting the Trust Fund. If, by the termination date, the Company has not notified the Trustee in writing as to whom the assets and cash are to be transferred and delivered, the Trustee may bring an appropriate action or proceeding for leave to deposit the assets and cash in a court of competent jurisdiction. The Trustee shall be reimbursed by the Fee Trust for all costs and expenses of the action or proceeding including, without limitation, reasonable attorneys' fees and disbursements if not paid directly by the Company or, to the extent that the Fee Trust is insufficient, on a pro rata basis from the other trust funds. ARTICLE XI ENFORCEMENT OF TRUST AGREEMENT 11.1 The Company shall have the right to enforce any provisions of this Trust Agreement. In any action or proceedings affecting the Fund the only necessary parties shall be the Company and the Trustee and, except as provided in Section 12.1 hereof or as otherwise required by applicable law, no other person shall be entitled to any notice or service of process. Any judgment entered in such an action or proceeding shall be binding and conclusive on all persons having or claiming to have any interest in the Fund. ARTICLE XII AMENDMENTS 12.1 Subject to the provisions of Section 12.3 hereof, the Committee may by written instrument, from time to time, amend or modify, in whole or in part, any or all of the provisions of this Trust Agreement, except to make it revocable or to increase the duties of the Trustee without its written consent. The Committee may delegate its authority to the President to the extent provided in any delegation instrument. The Trustee and the Participants under the Trusts shall receive written notice of any such amendment including any amendment under Section 12.3 hereof. 12.2 The Committee and the Trustee shall execute any mutually agreeable supplements to, or amendments of, this Trust Agreement as shall be necessary to give effect to any such amendment or modification. 12.3 Notwithstanding anything herein to the contrary, to the extent that the terms hereof are inconsistent with the terms of the Plans, the latter shall control as if the terms hereof had been amended accordingly; provided, that the terms of the Plans may not increase the duties of the Trustee as set forth in this Agreement without the Trustee's written consent. Further, upon a Change of Control of the Company, the Committee shall be precluded from amending this Agreement in any manner that adversely affects the entitlement of the Participants and beneficiaries that had accrued on or prior to the Change of Control or is funded pursuant to the provisions of Article XVI hereof but has not been completely distributed to the Par ticipants or beneficiaries, unless, in any such event, the Participant or beneficiary, as applicable, consents, in writing, to such amendment. Upon a Change of Control of the Company, this Section 12.3 shall be deemed to supersede any provision of the Plans which permits amendments of such Plans inconsistent with the terms hereof and this Section 12.3 shall constitute an amendment to such Plans. -10- ARTICLE XIII TERMINATION OF TRUST 13.1 Except as provided in Sections 4.2 or 16.2 hereof, no part of the corpus or income of the Fund shall be paid to the Company or be used for any purpose other than for the exclusive purpose of providing benefits to the Participants or beneficiaries prior to the satisfaction of all liabilities under the Plans; provided, however, that nothing in this Article shall be deemed to limit or otherwise prevent the payment from the Fund of expenses and other charges as provided in Article VIII hereof. The Trust may be prospectively discontinued by written instrument of the Committee at any time, but each Trust Fund may not be liquidated until the payment of all amounts accrued for the Participant (or beneficiary) under the terms of the Plans as of the date of such termination whether or not then due. In no event shall the discontinuance of the Trust accelerate the payment of a Participant's benefit under any of the Plans unless the Committee determines otherwise in its sole discretion. 13.2 Upon the liquidation of the Fund or any individual Trust Fund, after all payments required by Section 13.1 have been made to the Participant(s) (or beneficiary(ies)), any and all funds remaining in the Trust Fund or the Fund shall be paid to the Company and the Trustee shall promptly take such action as shall be necessary to transfer such assets to the Company or to add to the Shortfall Trust, as directed by the President in accordance with the funding policy established in accordance with Section 1.3 hereof. ARTICLE XIV NON-ALIENATION 14.1 Except to the extent otherwise required by law, (i) no amount payable to or in respect of the Participant at any time under the Trust Fund and no interest that the Participant has in the Trust Fund shall be subject in any manner to alienation by anticipation, sale, transfer, assignment, bankruptcy, pledge, attachment, charge or encumbrance of any kind, and any attempt to so alienate, sell, transfer, assign, pledge, attach, charge or otherwise encumber any such amount, whether presently or thereafter payable, shall be void; and (ii) the Trust Fund shall in no manner be liable for or subject to the debts or liabilities of the Participant. 14.2 No provision of this Trust Agreement shall be interpreted as conferring upon the Participant any rights in any Trust Fund established hereunder other than those of a general creditor of the Company. ARTICLE XV COMMUNICATIONS 15.1 Communications to the Company shall be addressed to it at Philadelphia Suburban Corporation, 762 Lancaster Avenue, Bryn Mawr, PA 19010, Attention: President, with a required copy to Morgan, Lewis & Bockius, 2000 One Logan Square, Philadelphia, PA 19103-6993, Attention: Robert J.
