SECOND AMENDMENT TO AQUA AMERICA, INC.
SUPPLEMENTAL PENSION BENEFIT PLAN
FOR SALARIED EMPLOYEES

(As Amended and Restated Effective January 1, 2008)

WHEREAS, Aqua America, Inc. (the “Company”) maintains the Aqua America, Inc.
Supplemental Pension Benefit Plan for Salaried Employees (the “Plan”) for the
benefit of a select group of management and highly compensated employees; and

WHEREAS, the Company and Nicholas DeBenedictis have entered into an Employment
Agreement; and

WHEREAS, Nicholas DeBenedictis (the “Participant”) made the one-time irrevocable
election, pursuant to and in accordance with Section 3.2(d), to transfer his
benefit hereunder to the Aqua America, Inc. Executive Deferral Plan; and

WHEREAS, the Company desires to amend the Plan in accordance with the Employment
Agreement between the Company and Nicholas DeBenedictis to increase the benefit
to be transferred to the Aqua America, Inc. Executive Deferral Plan for payment
to his Surviving Spouse in the event of his Separation from Service due to death
after age 55 and to clarify Section 3.4;

NOW, THEREFORE, effective immediately, the Plan is hereby amended to read as
follows:

1. Section 1.16 is hereby amended to read as follows:

1.16 “Surviving Spouse Benefit” means, except as otherwise provided in Section
3.2(d), the survivor annuity payable to the Surviving Spouse determined as if
the Participant had retired on the later of the day prior to his death or on the
date of his earliest retirement age (having survived to such date), with an
immediate joint and survivor annuity. The survivor annuity percentage shall be
75% with respect to Participants in Part A of the Retirement Plan and 50% with
respect to Participants in Part C of the Retirement Plan. A Surviving Spouse
Benefit shall be determined in the form of a single life annuity (based on such
survivor annuity) for the life of the Surviving Spouse commencing on the later
of the Participant’s date of death or earliest retirement age. Earliest
retirement age shall have the same meaning as under the Retirement Plan.

2. Section 3.2(d) is hereby amended by adding a sentence at the end thereof to
read as follows:

Notwithstanding the foregoing, or any other provision of this Plan to the
contrary, with respect to the participation of Nicholas DeBenedictis in the
event of his Separation from Service due to death after age 55, the Supplemental
Surviving Spouse Benefit to be transferred to the Aqua America, Inc. Executive
Deferral Plan shall be an amount equal to the actuarial equivalent present value
of the Supplemental Benefit that would have been transferred to such Executive
Deferral Plan had Mr. DeBenedictis retired on the day prior to the day of his
death.

3. Section 3.4 is hereby amended for clarification purposes by adding a sentence
at the end thereof to read as follows:

For avoidance of doubt, the Supplemental Benefit as of any date after the
Participant’s Normal Retirement Date shall be the greater of (i) the
Supplemental Benefit as of the Participant’s Normal Retirement Date increased by
one-half of one percent (1/2%) per month, for a Participant in Part A of the
Retirement Plan for the period from his Normal Retirement Date to the date of
determination or the Actuarial Equivalent of the Supplemental Benefit as of
Normal Retirement Date for a Participant in Part C of the Retirement Plan, or
(ii) the Supplemental Benefit calculated as of the date of determination.

IN WITNESS WHEREOF, Aqua America, Inc. has caused this Amendment to be duly
executed, under seal, this 31st day of       January     , 2010.
