                                AMENDED AGREEMENT

                  THIS Amended Agreement made as of the 7th day of August, 2001,
by and among Philadelphia Suburban Water Company, a Pennsylvania corporation
(the "Company"), Philadelphia Suburban Corporation, a Pennsylvania corporation
("PSC"), and Richard D. Hugus (the "Executive").

                  WHEREAS, the Executive is presently employed by the Company,
as its Vice President - Corporate Development; and

                  WHEREAS, the Company considers it essential to foster the
employment of well-qualified, key management personnel, and, in this regard, the
boards of directors of the Company and PSC recognize that, as is the case with
many publicly-held corporations such as PSC, the possibility of a change of
control of PSC may exist and that such possibility, and the uncertainty and
questions which it may raise among management, may result in the departure or
distraction of key management personnel to the detriment of the Company;
                  WHEREAS, the boards of directors of the Company and PSC have
determined that appropriate steps should be taken to reinforce and encourage the
continued attention and dedication of key members of the Company's management to
their assigned duties without distraction in the face of potentially disturbing
circumstances arising from the possibility of a change of control of PSC,
although no such change is now contemplated;

                  WHEREAS, in order to induce the Executive to remain in the
employ of the Company, the Company and PSC, for which certain of the employees
of the Company, such as the Executive, provide key executive services, entered
into an Agreement, effective as of January 1, 1997, to provide that the
Executive would receive certain compensation in the event his employment with
the Company is terminated subsequent to a "Change of Control" (as defined in
Section 1 hereof) of PSC as a cushion against the financial and career impact on
the Executive of any such Change of Control; and

                  WHEREAS, the agreement was amended effective as of November
30, 1998 and as of February 1, 1999, to clarify the term of the Agreement; and

                  WHEREAS, the Company wishes to amend and restate the Agreement
at this time to clarify certain rights of the Executive, incorporate the
amendment that was made to the Agreement effective as of February 1, 1999, and
to make other desirable changes; and

PSC or its subsidiaries;

                  3. Severance Compensation upon Termination.

                           (a) Subject to the provisions of Section 11 hereof,
in the event of the Executive's involuntary Termination of Employment for any
reason other than Cause or in the event of a Good Reason Termination, in either
event within two years after a Change of Control, the Company shall pay to the
Executive, upon the execution of a release in the form required by the Company
of its terminating executives prior to the Change of Control, within 15 days
after the Termination Date (or as soon as possible thereafter in the event that
the procedures set forth in Section 11(b) hereof cannot be completed within 15
days), an amount in cash equal to two times the Executive's Base Compensation,
subject to required employment taxes and deductions. PSC hereby guarantees the
obligations of the Company and, in the event that the Company does not satisfy
its obligation hereunder within the required time period, PSC shall pay or cause
to be paid all compensation, benefits and other amounts remaining due to the
Executive upon prompt written notice to PSC that the Company has not satisfied
its obligation (or a portion thereof) to the Executive.

                           (b) In the event the Executive's Normal Retirement
Date would occur prior to 12 months after the Termination Date, the aggregate
cash amount determined as set forth in (a) above shall be reduced by multiplying

3.

3 hereof shall be in addition to and not in lieu of any payments or benefits due
to the Executive under any other plan, policy or program of the Company, and its
Subsidiaries or Affiliates. In addition, the Executive shall be entitled to (i)
a continuation of health, dental, life and welfare benefits, excluding
disability benefits, otherwise provided to senior level executives or employees
generally, as the same may be amended for all such individuals from time to
time, for the period of two years, (ii) continued use of the automobile
furnished to the Executive for the lesser of (1) two years after the Termination
Date or (2) the balance of the applicable lease term, if any, in either case to
the same extent as was provided to the Executive in the calendar year

the Executive's choice for 6 months following the Termination Date.

                  5. Trust Fund. PSC sponsors an irrevocable trust fund pursuant
to a trust agreement to hold assets to satisfy its obligations to the Executive
under this Agreement. Funding of such trust fund shall be subject to the
discretion of PSC's President, as set forth in the agreement pursuant to which
the fund has been established.

                  6. Enforcement.

                           (a) In the event that the Company (or PSC, as
appropriate) shall fail or refuse to make payment of any amounts due the
Executive under Sections 3 and 4 hereof within the respective time periods
provided therein, the Company shall pay to the Executive, in addition to the
payment of any other sums provided in this Agreement, interest, compounded
daily, on any amount remaining unpaid from the date payment is required under
Section 3 or 4, as appropriate, until paid to the Executive, at the rate from
time to time announced by PNC Bank as its "prime rate" plus 1%, each change in
such rate to take effect on the effective date of the change in such prime rate.

                           (b) It is the intent of the parties that the
Executive not be required to incur any expenses associated with the enforcement
of his rights under this Agreement by arbitration, litigation or other legal
action because the cost and expense thereof would substantially detract from the
benefits intended to be extended to the Executive hereunder. Accordingly, the
Company shall pay the Executive on demand the amount necessary to reimburse the
Executive in full for all reasonable expenses (including all attorneys' fees and
legal expenses) incurred by the Executive in enforcing any of the obligations of
the Company under this Agreement.

                  7. No Mitigation. The Executive shall not be required to
mitigate the amount of any payment or benefit provided for in this Agreement by
seeking other employment or otherwise, nor shall the amount of any payment or
benefit provided for herein be reduced by any compensation earned by other
employment or otherwise.

                  8. Non-exclusivity of Rights. Nothing in this Agreement shall
prevent or limit the Executive's continuing or future participation in or rights
under any benefit, bonus, incentive or other plan or program provided by the
Company, or any of its Subsidiaries or Affiliates, and for which the Executive
may qualify.

                  9. No Set-Off. The Company's obligation to make the payments
provided for in this Agreement and otherwise to perform its obligations
hereunder shall not be affected by any circumstances, including, without
limitation, any set-off, counterclaim, recoupment, defense or other right which
the Company may have against the Executive or others.

                  10. Taxes. Any payment required under this Agreement shall be
subject to all requirements of the law with regard to the withholding of taxes,
filing, making of reports and the like, and the Company shall use its best
efforts to satisfy promptly all such requirements.

                  11. Certain Reduction of Payments.

                           (a) Anything in this Agreement to the contrary
notwithstanding, in the event that it shall be determined that any payment or
distribution by the Company to or for the benefit of the Executive, whether paid
or payable or distributed or distributable pursuant to the terms of this
Agreement or otherwise (a "Payment"), would constitute an "excess parachute
payment" within the meaning of Section 280G of the Internal Revenue Code of
1986, as amended (the "Code"), the aggregate present value of amounts payable or
distributable to or for the benefit of the Executive pursuant to this Agreement
(such payments or distributions pursuant to this Agreement are hereinafter
referred to as "Agreement Payments") shall be reduced (but not below zero) to
the Reduced Amount. The "Reduced Amount" shall be an amount expressed in present
value, which maximizes the aggregate present value of Agreement Payments without
causing any Payment to be subject to the loss of deduction under Section 280G of
the Code. For purposes of this Section 11, present value shall be determined in
accordance with Section 280G(d)(4) of the Code.

                           (b) All determinations to be made under this Section
11 shall be made by PSC's independent public accountant immediately prior to the
Change of Control (the "Accounting Firm"), which firm shall provide its
determinations and any supporting calculations both to the Company and the
Executive within 10 days of the Termination Date. Any such determination by the
Accounting Firm shall be binding upon the Company and the Executive. The
Executive shall then have the right to determine which of the Agreement Payments
shall be eliminated or reduced in order to produce the Reduced Amount in
accordance with the requirements of this Section. Within five days after this
determination, the Company shall pay (or cause to be paid) or distribute (or
cause to be distributed) to or for the benefit of the Executive such amounts as
are then due to the Executive under this Agreement.

                           (c) As a result of the uncertainty in the application
of Section 280G of the Code at the time of the initial determination by the
Accounting Firm hereunder, it is possible that Agreement Payments, as the case
may be, will have been made by the Company which should not have been made
("Overpayment") or that additional Agreement Payments which have not been made
by the Company could have been made ("Underpayment"), in each case, consistent
with the calculations required to be made hereunder. Within two years after the
Termination of Employment, the Accounting Firm shall review the determination
made by it pursuant to the preceding paragraph and the Company shall cooperate
and provide all information necessary for such review. In the event that the
Accounting Firm determines that an Overpayment has been made, any such
Overpayment shall be treated for all purposes as a loan to the Executive which
the Executive shall repay to the Company together with interest from the date of
payment under this Agreement at the applicable Federal rate provided for in
Section 7872(f)(2) of the Code (the "Federal Rate"); provided, however, that no
amount shall be payable by the Executive to the Company if and to the extent
such payment would not reduce the limit on the amount that is deductible under
Section 280G of the Code. In the event that the Accounting Firm determines that
an Underpayment has occurred, any such Underpayment shall be promptly paid by
the Company to or for the benefit of the Executive together with interest from
the date of payment under this Agreement at the Federal Rate.

                           (d) All of the fees and expenses of the Accounting
Firm in performing the determinations referred to in subsections (b) and (c)
above shall be borne solely by the Company. The Company agrees to indemnify and
hold harmless the Accounting Firm of and from any and all claims, damages and
expenses resulting from or relating to its determinations pursuant to
subsections (b) and (c) above, except for claims, damages or expenses resulting
from the gross negligence or willful misconduct of the Accounting Firm.

                  12. Term of Agreement. The term of this Agreement shall be
indefinite until the Company notifies the Executive in writing that this
Agreement will not be renewed at least sixty days prior to the proposed
termination; provided, however, that (i) after a Change of Control during the
term of this Agreement, this Agreement shall remain in effect until all of the
obligations of the parties hereunder are satisfied or have expired, and (ii)
this Agreement shall terminate if, prior to a Change of Control, the employment
of the Executive with the Company and its Subsidiaries, as the case may be,
shall terminate for any reason; provided, however, that if a Change of Control
occurs within 18 months after (a) the Executive's termination incurred for any
reason other than a voluntary resignation or retirement (a Good Reason
Termination shall not be deemed voluntary) or termination for Cause or (b) the
termination of this Agreement, the Executive shall be entitled to all of the
terms and conditions of this Agreement as if the Executive's termination had
occurred on the date of the Change of Control.

                  13. Successor Company. PSC shall require any successor or
successors (whether direct or indirect, by purchase, merger or otherwise) to all
or substantially all of the business and/or assets of PSC or the Company, or of
any of their Subsidiaries that actually employ the Executive, by agreement in
form and substance satisfactory to the Executive, to acknowledge expressly that
this Agreement is binding upon and enforceable against the successor or
successors, in accordance with the terms hereof, and to become jointly and
severally obligated with PSC and the Company to perform this Agreement in the
same manner and to the same extent that PSC and the Company would be required to
perform if no such succession or successions had taken place. Failure of PSC or
the Company to notify the Executive in writing as to such successorship, to
provide the Executive the opportunity to review and agree to the successor's
assumption of this Agreement or to obtain such agreement prior to the
effectiveness of any such succession shall be a breach of this Agreement. As
used in this Agreement, PSC and the Company shall mean PSC and the Company,
respectively, and their Subsidiaries as hereinbefore defined and any such
successor or successors to their business and/or assets, jointly and severally.

                  15 Governing Law. This Agreement shall be governed by and
interpreted under the laws of the Commonwealth of Pennsylvania without giving
effect to any conflict of laws provisions.

                  16. Contents of Agreement, Amendment and Assignment. This
Agreement supersedes all prior agreements, sets forth the entire understanding
between the parties hereto with respect to the subject matter hereof and cannot
be changed, modified, extended or terminated except upon written amendment
executed by the Executive and the Company's Chairman of the Company's Executive
Compensation and Employee Benefits Committee, or its successor. The provisions
of this Agreement may require a variance from the terms and conditions of
certain compensation or bonus plans under circumstances where such plans would
not provide for payment thereof in order to obtain the maximum benefits for the
Executive. It is the specific intention of the parties that the provisions of
this Agreement shall supersede any provisions to the contrary in such plans, and
such plans shall be deemed to have been amended to correspond with this
Agreement without further action by the Company or the Board.

                  17. No Right to Continued Employment. Nothing in this
Agreement shall be construed as giving the Executive any right to be retained in
the employ of the Company.

                  18. Successors and Assigns. All of the terms and provisions of
this Agreement shall be binding upon and inure to the benefit of and be
enforceable by the respective heirs, representatives, successors and assigns of
the parties hereto, except that the duties and responsibilities of PSC and the
Company hereunder shall not be assignable in whole or in part.

                  19. Severability. If any provision of this Agreement or
application thereof to anyone or under any circumstances shall be determined to
be invalid or unenforceable, such invalidity or unenforceability shall not
affect any other provisions or applications of this Agreement which can be given
effect without the invalid or unenforceable provision or application.

                  20. Remedies Cumulative; No Waiver. No right conferred upon
the Executive by this Agreement is intended to be exclusive of any other right
or remedy, and each and every such right or remedy shall be cumulative and shall
be in addition to any other right or remedy given hereunder or now or hereafter
existing at law or in equity. No delay or omission by the Executive in
exercising any right, remedy or power hereunder or existing at law or in equity
shall be construed as a waiver thereof.

                  21. Miscellaneous. All section headings are for convenience
only. This Agreement may be executed in several counterparts, each of which is
an original. It shall not be necessary in making proof of this Agreement or any
counterpart hereof to produce or account for any of the other counterparts.

                  22. Arbitration. In the event of any dispute under the
provisions of this Agreement other than a dispute in which the sole relief
sought is an equitable remedy such as an injunction, the parties shall be
required to have the dispute, controversy or claim settled by arbitration in
Bryn Mawr, Pennsylvania, in accordance with the National Rules for the
Settlement of Employment Disputes of the American Arbitration Association,
before one arbitrator who shall be an executive officer or former executive
officer of a publicly traded corporation, selected by the parties. Any award
entered by the arbitrator shall be final, binding and nonappealable and judgment
may be entered thereon by either party in accordance with applicable law in any
court of competent jurisdiction. This arbitration provision shall be
specifically enforceable. The arbitrator shall have no authority to modify any
provision of this Agreement or to award a remedy for a dispute involving this
Agreement other than a benefit specifically provided under or by virtue of the
Agreement. The Company shall be responsible for all of the fees of the American
Arbitration Association and the arbitrator and any expenses relating to the
conduct of the arbitration (including reasonable attorneys' fees and expenses).

bound, have executed this Agreement as of the date first above written.
