                                    PART I
 
ITEM 1. BUSINESS
 
     Philadelphia Suburban Corporation ('PSC' or the 'Registrant'), a
Pennsylvania corporation, was incorporated in 1968. The business of PSC is
conducted almost entirely through its subsidiary Philadelphia Suburban Water
Company ('PSW'), a regulated public utility. PSC also owns a small data
processing service operation, Utility & Municipal Services, Inc. The information
appearing in 'Management's Discussion and Analysis' from the portions of PSC's
1993 Annual Report to shareholders filed as Exhibit 13 to this Form 10-K Report
is incorporated by reference herein.
 
     In the third quarter of 1990, the Board of Directors authorized the sale of
Mentor Information Systems, Inc., Digital Systems, Inc., American Tele/Response
Group, Inc., Stoner Associates, Inc., and its subsidiary Kesler Engineering,
Inc.; and during the first quarter of 1991, the Board of Directors authorized
the sale of PSC Engineers & Consultants, Inc. During 1991, all the businesses
were sold except for American Tele/Response Group, Inc. and Kesler Engineering,
Inc., which were sold in the first quarter of 1993. The results of operations of
these businesses are accounted for as discontinued operations. Unless otherwise
indicated, as used herein the 'Company' includes the continuing operations of
both PSC and its consolidated subsidiaries. The sales of the non-water service
subsidiaries were authorized in order to allow the Company to concentrate its
activities on its core water utility operations.
 
     Consistent with that decision, in December 1993, PSW acquired the water
utility assets and franchise rights of the Borough of Malvern for $1,323,000 in
cash. The acquisition of this water system added approximately 859 customers or
.3% to PSW's customer base and one square mile of service territory or .3% to
PSW's existing service territory. PSW has made a proposal to acquire a municipal
water system serving approximately 13,000 customers in an area contiguous to
PSW's service territory for a purchase price in excess of $20,000,000, although
there can be no assurance that the proposal will be accepted or that such a
transaction will be consummated. PSW is not currently a party to any definitive
agreement with respect to any pending acquisition. In December 1992, PSW
acquired the water utility assets of the West Whiteland Township and the Uwchlan
Township Municipal Authority water systems for $9,128,257 in cash and the
issuance of $1,776,947 in debt. The December 1992 acquisitions added
approximately 6,900 customers or 2.9% to PSW's customer base and 40 square miles
of service territory or 11.8% to PSW's existing service territory.
 
                      PHILADELPHIA SUBURBAN WATER COMPANY
 
     General.  PSW is an operating public utility company, which supplies water
to approximately 247,195 residential, commercial, industrial and public
customers. PSW's contiguous service territory is approximately 380 square miles,
comprising a large portion of the suburban area west and north of the City of
Philadelphia. This territory is primarily residential in nature and is
completely metered, except for fire hydrant service.
 
     Based on the 1990 census, PSW estimates that the total number of persons
currently served is approximately 800,000. Excluding the customers that were
added as a result of the acquisitions in December 1993 and 1992, customer
accounts have grown at an average rate of approximately .6% per annum for the
last three years.

     Water supplies and usage.  PSW derives its principal supply of water from
the Schuylkill River, five rural streams which are tributaries of the Schuylkill
and Delaware Rivers, and the Upper Merion Reservoir, a former quarry now
impounding groundwater. All of these are either within or adjacent to PSW's
service territory. PSW acquired the right to remove water from these sources,
and in connection with such rights, PSW has secured the necessary regulatory
approvals. PSW has constructed five impounding reservoirs and four treatment and
pumping facilities to provide storage and purification of these surface water
supplies.
 
     The Pennsylvania Department of Environmental Resources ('DER') has
regulatory power with respect to sources of supply and the construction,
operation and safety practices for certain dams and other water containment
structures under the Pennsylvania Dam Safety and Encroachments Act of 1979.
PSW's dams are in compliance with these requirements in all material respects.
 
     PSW's surface supplies are supplemented by 39 wells. PSW also has
interconnections with: the Chester Water Authority, which permits PSW to
withdraw up to 6.2 million gallons per day ('mgd'); the Bucks County Water and
Sewer Authority, which provides for a supply of up to 7.0 mgd; and the West
Chester Area Municipal Authority, which provides up to a maximum of 1.0 mgd.
Agreements regarding the first two interconnections require PSW to purchase
certain minimum amounts of water. PSW believes it possesses all the necessary
permits to obtain its supply of water from the sources indicated above.
 
     The minimum safe yield of all sources of supply described above, based on
low stream flows of record with respect to surface supplies, is as follows:
 
<TABLE>
<S>                                                  <C>        <C>
Surface supplies...................................       90.5 mgd
Upper Merion Reservoir.............................        7.2
Wells..............................................       17.7
Purchased supplies.................................        8.1
                                                     ---------
     Total.........................................      123.5 mgd
                                                     ---------  
                                                     ---------  
</TABLE>
 
     During periods of normal precipitation, the safe yield is more than the
minimum shown above. Under normal operating conditions, PSW can deliver a
maximum of 139 mgd to its distribution system for short periods of time. The
average daily send-out for 1993, 1992 and 1991 was 89.1, 85.4, and 87.2 mgd,
respectively.
 
     The maximum demand ever placed upon PSW's facilities for one month occurred
during June 1988, when send-out averaged 101.4 mgd. The peak day of record
occurred during July 1993 when water use reached 118.8 mgd.
 
     Actual water usage (as measured by the water meters installed at each
service location) is less than the amount of water delivered into the system due
to leaks, PSW's operational use of water, fire hydrant usage and other similar
uses. Water consumption per customer is affected by local weather conditions
during the year. In general, during the late spring and summer, an increase in
rainfall 
 
                                       4
<PAGE>


reduces water consumption, while a decrease in rainfall increases it.
Also, an increase in the average temperature generally causes an increase in
water consumption.
 
     Energy supplies.  PSW does all of its pumping using electric power
purchased from PECO Energy Company. Energy supplies have been sufficient to meet
customer demand.
 
     Water shortages.  The Delaware River Basin, which is the drainage area of
the Delaware River from New York State to Delaware, periodically experiences
water shortages during the summer months. To the extent that the reservoirs in
the upper part of the Basin are affected by a lack of precipitation, the
Delaware River Basin Commission (the 'DRBC') may impose either voluntary or
mandatory water use restrictions on portions or all of the Basin.
 
     PSW's raw water supplies have generally been adequate to meet customer
demand for the past five years principally because of its five impounding
reservoirs. However, since PSW's service territory is within the Basin, PSW's
customers may be required to comply with DRBC water use restrictions, even if 
PSW's supplies are adequate, if the availability of water
in the entire DRBC area is inadequate.
 
     During 1988 and the two preceding years, the lower regions of the Basin
experienced hot, dry weather conditions while the upper regions of the Basin
enjoyed normal or above normal precipitation. During all three years PSW had
sufficient quantities of raw water available and no drought restrictions were
imposed by the DRBC. However, in the summer of 1988, with the record breaking
heat and the resulting high water demand created by lawn sprinkling, PSW imposed
restrictions banning nonessential water uses in order to maintain adequate
storage levels of treated water and to reduce peak demands in the distribution
system. No water use restrictions were imposed by PSW in the years subsequent to
1988. The addition of the 15 mgd Pickering Creek treatment plant in 1991 and
improvements to the distribution system in the past five years have reduced the
possibility of PSW issuing water use restrictions in the future due to demands
on its system.
 
     Regulation by the Pennsylvania Public Utility Commission.  PSW is subject
to regulation by the Pennsylvania Public Utility Commission (the 'PUC') which
has jurisdiction with respect to rates, service, accounting procedures, issuance
of securities and other matters.
 
     Under applicable Pennsylvania statutes, PSW has rights granted under its
Articles of Incorporation and by certificates of public convenience from the PUC
authorizing it to conduct its present operations in the manner in which such
operations are now conducted and in the territory in which it now renders
service, to exercise the right of eminent domain and to maintain its mains in
the streets and highways of such territory. Such rights are generally
nonexclusive, although it has been the practice of the PUC to allow only one
water company to actually provide service to a given area. Consequently, PSW is
subject to competition only with respect to potential customers located on the
fringe of areas that it presently serves who also may have access to the service
of another water supplier.
 
     In 1992, the PUC issued a policy statement which, under certain
circumstances, required utilities to extend service to new customers without the
benefit of a customer advance for construction. As a result of various problems
and uncertainties associated with the implementation of this policy statement,
the PUC initiated a rulemaking procedure in December 1993, intended to
facilitate the development of practical standards by which the broad policy
statement can be applied. The Company believes that when instituted, the new
standards will reflect the position that the cost of service extensions should
be justified by anticipated revenues from the extension or should be paid by the
service applicant.
 
     Water Quality & Environmental Issues.  PSW is subject to regulation of
water quality by the U.S. Environmental Protection Agency ('EPA') under the
Federal Safe Drinking Water Act (the 'SDWA') and by the Pennsylvania Department
of Environmental Resources ('DER') under the Pennsylvania Safe Drinking Water
Act. The SDWA provides for the establishment of uniform  

                                       5
<PAGE>

minimum national water quality standards, as well as governmental authority to 
specify the type of treatment process to be used for public drinking water. 
PSW is presently in compliance with all standards and treatment requirements 
promulgated to date.
 
     The EPA has an ongoing directive to issue additional regulations under the
SDWA. The directive was clarified in 1986 when Congress amended the SDWA to
require, among other revisions, disinfection of all drinking water, additional
maximum contaminant level ('MCL') specifications, and filtration of all surface
water supplies. PSW has already installed the necessary equipment to provide for
the disinfection of the drinking water throughout the system and is monitoring
for the additional specified contaminants. PSW's principal surface water
supplies are currently filtered. PSW began to provide full filtration of its
supply from the Upper Merion Reservoir in November 1993 upon the completion of a
filtration facility at that location. This facility was necessary in order to
maintain PSW's compliance with the SDWA.
 
     In addition, the 1986 SDWA Amendments require the EPA to promulgate MCLs
for many chemicals not previously regulated. EPA has to date promulgated MCLs
for numerous additional
contaminants and is required to mandate further MCLs every three years.
Promulgation of additional MCLs by the EPA in the future may require PSW to
change some of its treatment techniques, however, PSW meets all existing MCL
requirements and believes that the currently proposed MCLs will not have a
significant impact on its capital requirements or operating expenses. In 1991,
the EPA proposed regulations pertaining to radionuclides (including radon).
Recently, the Congress placed a one year moratorium on radon regulations.
Depending upon the final MCLs permitted, PSW will likely be required to take
remedial action at certain of its groundwater facilities. The remediation
options presently under evaluation include dilution, treatment, or replacement
of the supply with other groundwater or surface water supplies. Based on the MCL
initially proposed, it is anticipated that the capital costs of compliance will
range from $2.5 to $3.5 million over the next 10 years. PSW may, in the future,
have to change its method of treating drinking water at certain of its sources
of supply if additional regulations become effective.
 
     In June, 1991, EPA promulgated final regulations for lead and copper (the
'Lead and Copper Rule'). Under the Lead and Copper Rule, large water utilities
are required to conduct corrosion control studies and to sample certain
high-risk customer homes to determine the extent of treatment techniques that
may be required. PSW conducted the two required rounds of sampling in 1992 and
did not exceed the EPA action levels for either lead or copper. Additional
sampling will be required in the future. PSW has developed a corrosion control
program for its surface sources of supply and does not foresee the need to make
any major additional treatment changes or capital expenditures as a result of
the Lead and Copper Rule.
 
     On January 1, 1993, new federal regulations ('Phase II') became effective
for certain volatile organics, herbicides, pesticides and inorganic parameters.
Although PSW will not be required by the DER to monitor for most of these
parameters until 1995, PSW has already done substantial monitoring. In the few
cases where Phase II contaminants were detected, concentrations were below MCLs.
Future monitoring will be required, but no major treatment modifications are
anticipated as a result of these regulations.
 
     PSW is also subject to other environmental statutes administered by the EPA
and DER. These include the Federal Clean Water Act and the Resource Conservation
and Recovery Act ('RCRA'). Under the Federal Clean Water Act, the Company must
obtain National Pollutant Discharge Elimination System ('NPDES') permits for
discharges from its treatment stations. PSW currently maintains three NPDES
permits relating to its surface water treatment plants, which are subject to
renewal every five years. During the past five years, PSW has installed the
required waste water treatment facilities and presently meets all NPDES
requirements. Although management recognizes that permit renewal may become more
difficult if more stringent guidelines are imposed, no significant obstacles to
permit renewal are presently foreseen.
 
                                       6
<PAGE>
 
     Under RCRA, PSW is subject to specific regulations regarding the solid
waste generated from the water treatment process. The DER promulgated 'Final
Rulemaking' for solid waste (Residual Waste Management) in July 1992. PSW has
retained an engineering consultant to assist with the extensive monitoring,
record keeping and reporting required under these regulations. A preliminary
application for permitting has been filed, and formal permitting of these
facilities should be completed by 1996 in accordance with regulatory
requirements.
 
     Where PSW is required to make certain capital investments in order to
maintain its compliance with any of the various regulations discussed above, it
is management's belief that all such expenditures would be fully recoverable in
PSW's water rates. However, the capital costs, under current law, would have to
be financed prior to their inclusion in PSW's rate structure, and the resulting
rate increases would not necessarily be timely.



                       UTILITY & MUNICIPAL SERVICES, INC.
 
     Utility & Municipal Services, Inc. ('UMS') provides data processing
services to several water utilities including PSW, and to several municipal
water and sewer systems. The services provided to the utilities and
municipalities include billing services and the processing of financial reports.
 
                               EMPLOYEE RELATIONS
 
     As of December 31, 1993, the Registrant employed a total of 523 persons, of
which 511 are employees of PSW. Hourly employees of PSW are represented by the
International Brotherhood of Firemen and Oilers, Local No. 473. The contract
with the union expires on December 1, 1994. Management considers its employee
relations to be satisfactory.
 
ITEM 2. PROPERTIES
 
     The Registrant believes that the facilities used in the operation of its
various businesses are generally in excellent condition in terms of suitability,
adequacy and utilization.
 
     The property of PSW consists of a waterworks system devoted to the
collection, storage, treatment and distribution of water in its service
territory. Management considers that its properties are maintained in good
operating condition and in accordance with current standards of good waterworks
practice. The following table summarizes the principal physical properties owned
by PSW:

</TABLE>
 
     In addition, PSW also owns 45 standpipes with a combined distribution
storage capacity of 137.9 million gallons and five surface water impounding
reservoirs. The water utility also owns approximately 2,960 miles of
transmission and distribution mains, has 247,195 active metered services and
10,991 fire hydrants.
 
     PSW's properties referred to herein, with certain minor exceptions which do
not materially interfere with their use, are owned and are subject to the lien
of an Indenture of Mortgage dated as of January 1, 1941, as supplemented. In the
case of properties acquired through the exercise of the power of eminent domain
and certain properties acquired through purchase, it has title only for water
supply purposes.

     The Registrant's corporate offices and the facilities of UMS are leased
from PSW and located in Bryn Mawr, Pennsylvania.
 
ITEM 3. LEGAL PROCEEDINGS
 
     There are no pending legal proceedings to which the Registrant or any of
its subsidiaries is a party or to which any of their properties is the subject
that present a reasonable likelihood of a material adverse impact on the
Registrant. In March of 1992, PSW received notice of an arbitration proceeding
against the New Jersey Spill Fund by a party claiming damages of approximately
$2.5 million as a result of a fire at a warehouse in Newark, New Jersey, where
hazardous substances had been stored. The Spill Fund had previously denied this
claim, but the claimant demanded an arbitration proceeding to review the claim.
If the claimant is successful in the arbitration proceeding, the Spill Fund
could commence a civil action seeking to recover the amount of its payment to
the claimant from a group of over 70 entities, including PSW, who have been
identified as having some of their material stored at the warehouse. The Company
does not believe that any assessment against the Company as a result of
the arbitration proceeding will be material to the business or financial
condition of the Company. PSW has also been advised that on February 15, 1994
the State of New Jersey and the Spill Fund instituted a separate action 
against approximately 100 entities in the Superior Court of New Jersey Law
Division -- Essex County seeking to recover, among other related expenses, the
State's cost of $3.82 million in cleaning up the site of the Newark warehouse. 
PSW is one of the defendants named in the Complaint, but PSW has not been 
served with a Complaint as of March 24, 1994. PSC does not believe that any 
assessment against PSW as a result of this action will be material to the 
business or financial condition of PSC.



 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
     No matters were submitted to a vote of security holders during the fourth

Under date of February 1, 1994, we reported on the consolidated balance sheets

and 1992 and the related consolidated statements of income and cash flows for
each of the years in the three-year period ended December 31, 1993, as contained
in the 1993 Annual Report to shareholders. These consolidated financial
statements and our report thereon are incorporated by reference in the annual
report on Form 10-K for the year 1993. In connection with our audits of the
aforementioned consolidated financial statements, we also have audited the
related additional financial data listed in Item 14. -- Financial Statement
Schedules of this report on Form 10-K. These financial statement schedules are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statement schedules based on our audits.
 
In our opinion, such additional financial data, when considered in relation to
the basic consolidated financial statements taken as a whole, present fairly, in
all material respects the information set forth therein.

interest payment date next preceding the date of this bond (or if this bond be
dated prior to October 1, 1993, from the date hereof) until the principal hereof
shall become due and payable, at the rate of seven and 15/100ths percent (7.15%)

     The interest so payable will (except as otherwise provided in the
Twenty-Eighth Supplemental Indenture referred to herein) be calculated on the
basis of a 360-day year of twelve 30-day months and be paid to the person in
whose name this bond (or a bond or bonds in exchange for which this bond was

aggregate principal amount except as set forth in the Indenture hereinafter
mentioned in one or more series and equally secured (except insofar as a sinking

supplemental thereto reference is hereby made for a description of the property
mortgaged and pledged, the nature and extent of the security, the rights of the
holders and registered owners of the bonds and of the Trustee in respect of such
security, and the terms and conditions under which the bonds are and are to be
secured and may be issued under the Indenture; but neither the foregoing
reference to the Indenture nor any provision of this bond or of the Indenture or
of any indenture supplemental thereto shall affect or impair the obligation of
the Company, which is absolute and unconditional, to pay at the stated or
accelerated maturity herein and in the Indenture provided, the principal of and
interest and premium, if any, on this bond as herein provided. 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

of April 1, 1993, and designated therein as 'First Mortgage Bonds, 7.15% Series
due 2008 (the 'bonds of the 7.15% series due 2008').
 
     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
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
 
                                       5

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 7.15% series due 2008 are subject to redemption prior to
maturity in part on April 1 of each year, commencing April 1, 1998, pursuant to
the terms of a sinking fund provided in the Twenty-Eighth Supplemental Indenture
at a price equal to one hundred percent (100%) of the principal amount of the
bonds to be redeemed, together with unpaid interest accrued to the date fixed
for redemption.
 
     The bonds of the 7.15% series due 2008 are subject to redemption at the
option of the Company, either as a whole or in part, on any 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 a redemption price equal to
the principal amount of bonds of the 7.15% series due 2008 to be redeemed plus
interest thereon to the date of redemption plus a premium, as provided in the
Twenty-Eighth Supplemental Indenture.
 
     The bonds of the 7.15% series due 2008 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
7.15% series due 2008 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 date fixed for
redemption.
 
     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, as supplemented,
interest shall cease to accrue hereon or on such portion, as the case may be,
from and after the date fixed for redemption.
 
     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, as supplemented, upon the happening of an event of default, as in
the Indenture, as supplemented, provided; subject, however, to the right, under
certain circumstances, of the registered owners of a majority in principal
amount of bonds of the 7.15% series due 2008 outstanding to annul such
declaration.
 
     This bond is transferable by the registered owner hereof in person or by
attorney duly authorized in writing, on books of the Company to be kept for that
purpose at the principal corporate trust office of the Trustee in the City of
Philadelphia, Pennsylvania, upon surrender hereof for cancellation at such
office and upon presentation of a written instrument of transfer duly executed,
and thereupon the Company shall issue in the name of the transferee or
transferees, and the Trustee shall authenticate and deliver, a new bond or bonds
in authorized denominations, of equal aggregate unpaid principal amount. Any
such transfer or exchange shall be subject to the terms and conditions and to
the payment of the charges specified in the Indenture.
 
     The Company and the Trustee 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.
 
     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
 
                                       6

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, as supplemented.
 
     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 CoreStates Bank, N.A., as Trustee under the Indenture, or a successor
trustee thereunder shall have signed the certificate of authentication endorsed
hereon.

                                       9
<PAGE>
and shall be equally secured hereby and thereby, with the same effect as if said

date thereof; subject, however, to the provisions with reference to extended,

Indenture and subject to any sinking or improvement fund or maintenance deposit
provisions, or both, for the benefit of any particular series of bonds.
 
     IT IS HEREBY COVENANTED, DECLARED AND AGREED, by and between the parties
hereto, that all such bonds and coupons are to be authenticated, delivered and
issued, and that all property subject or to become subject hereto is to be held
subject to the further covenants, conditions, uses and trusts hereinafter set

or both, as follows:
 
                                   ARTICLE I.
     FORM, AUTHENTICATION AND DELIVERY OF THE BONDS; REDEMPTION PROVISIONS
 
     SECTION 1. There shall be a thirty-fourth series of bonds, limited in
aggregate principal amount to $22,000,000, designated as 'Philadelphia Suburban
Water Company First Mortgage Bonds, 7.15% Series due 2008' (the 'Bonds').
 
     Interest on the Bonds shall be payable semiannually on April 1 and October
1 of each year (each an 'interest payment date'), commencing October 1, 1993.
Each Bond shall be dated the date of its authentication and shall bear interest
from the interest payment date next preceding its date, unless authenticated on
an interest payment date, in which case it shall bear interest from such
interest payment date, or, unless authenticated prior to the first interest
payment date for the Bonds, in which case it shall bear interest from the date
of original authentication and delivery of the Bonds; provided, however, that if
at the time of authentication of any Bond interest on the predecessor Bond of
such Bond is in default, such Bond shall bear interest from the date to which
interest has been paid, or, if no interest has been paid from the date of
original authentication and delivery of the Bonds. The Bonds shall be stated to
mature (subject to the right of earlier redemption at the prices and dates and
upon the terms and conditions hereinafter set forth) and shall bear interest at
the rates set forth below:

</TABLE>
 
Principal of any Bond, premium, if any, thereon and, to the extent legally
enforceable, any installment of interest not paid when due shall bear interest
at a rate equal to the rate borne by such Bond plus two percent (2%).
 
     The Bonds shall be issuable only as registered bonds without coupons, shall
be in the form hereinabove recited, in the denomination of Five Thousand Dollars
($5,000) or any integral multiple thereof, shall be lettered 'R', and shall bear
such numbers as the Company may reasonably require.
 
     The principal of, and premium, if any, and interest on the Bonds shall be
payable at the corporate trust office of the Trustee in the City of
Philadelphia, Pennsylvania, 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; provided, however, that each payment of principal, interest and
premium, if any, to the holders of the Bonds shall be paid by the Trustee, with
funds received from the Company, by bank wire transfer of immediately available
funds pursuant to instructions respectively incorporated in those certain
Purchase Agreements dated as of April 1, 1993, between such person and the
Company, as such instructions may be modified from time to time as provided in
said Purchase Agreements.
 
     Notwithstanding any provisions of the Indenture to the contrary, no holder
of the Bonds shall be required to present or surrender such Bonds to the
Company, the Trustee or any other person prior to, or as a condition of,
receiving payment of any kind in respect thereof. All holders of the Bonds shall
 
                                       10
<PAGE>
deliver to the Trustee all Bonds registered in their names at the time of final
payment in full of all amounts due in respect thereof within a reasonable time
period after receipt of such final payment.
 
     The person in whose name any Bond is registered at the close of business on
any record date (as hereinafter defined) with respect to any payment date shall
be entitled to receive the principal, premium, interest or other payment payable
on such payment date, notwithstanding the cancellation of such Bond upon any
transfer or exchange subsequent to the record date and prior to such payment
date; provided, however, that if and to the extent the Company shall default in
the payment of the interest due on an interest payment date, such defaulted
interest shall be paid to the persons in whose names outstanding Bonds are
registered at the close of business on a subsequent record date established by
notice given by mail by or on behalf of the Company to the holders of Bonds not
less than fifteen (15) days preceding such subsequent record date, such record
date to be not less than ten (10) days preceding the date of payment of such
defaulted interest. The term 'record date' as used in this Section I with
respect to any regular interest payment date shall mean the fifteenth day of the
calendar month next preceding the calendar month in which such interest payment
date occurs if such fifteenth day is a business day; if such fifteenth day is
not a business day, the record date shall be the next preceding business day.
 
     Exchange of any Bonds shall be effected in accordance with the applicable
provisions of Sections 7, 8 and 9 of Article II of the Original Indenture.
 
     The text of the Bonds and of the certificate of the Trustee upon such Bonds
shall be, respectively, substantially of the tenor and effect hereinbefore
recited.
 
     SECTION 2. The Company shall establish a Sinking Fund for the benefit and
security of the Bonds and shall pay to the Trustee on or before the first day of
April (the 'Mandatory Redemption Date') in each year commencing April 1, 1998 to
and including April 1, 2007 a sum in cash sufficient to redeem on such Mandatory
Redemption Date $2,000,000 principal amount of bonds of said series, which shall
be applied on such Mandatory Redemption Date to the redemption of bonds of said
series at one hundred percent (100%) of the principal amount thereof, together
interest accrued thereon to the date fixed for redemption.
 
     For the purposes of this Section 2, any redemption of less than all of the
Bonds pursuant to Section 3 hereof shall be applied to the scheduled principal
payments of such series in inverse chronological order.
 
     SECTION 3. The Bonds shall be redeemable at the option of the company,
either as a whole or in part at any time at one hundred percent (100%) of the
principal amount thereof, together with interest accrued thereon to the date
fixed for redemption, plus a premium equal to the 'Make-Whole Premium'
determined five (5) business days prior to the date fixed for redemption;
provided, that the Company shall furnish notice to the Trustee and to each
holder of the Bonds by telecopy or other same day communication, on a date at
least two (2) business days prior to the date fixed for redemption of the
Make-Whole Premium, if any, applicable to such redemption and the calculations,
in reasonable detail, used to determine the amount thereof.
 
As used herein, the following terms have the meanings set forth:
 
     'Make-Whole Premium' shall mean, in connection with any redemption of the
Bonds, the excess, if any, of (i) the aggregate present value as of the date of
such redemption of each dollar of principal of the Bonds being redeemed (taking
into account the application of such redemption required by Section 2 of this
Twenty-Eighth Supplemental Indenture) and the amount of interest (exclusive of
interest accrued to the date of redemption) that would have been payable in
respect of such dollar amount if such redemption had not been made, determined
by discounting such amounts at the Reinvestment Rate from the respective dates
on which they would have been payable, over (ii) 100% of the principal amount of
the outstanding Bonds being redeemed. If the Reinvestment Rate is equal to or
higher than the interest rate of the Bonds being redeemed, the Make-Whole
Premium shall be zero.
 
                                       11
<PAGE>
     'Reinvestment Rate' shall mean the sum of (i) 0.5% plus (ii) the arithmetic
mean of the yields under the respective headings 'This Week' and 'Last Week'
published in the Statistical Release under the caption 'Treasury Constant
Maturities' for the maturity (rounded to the nearest month) corresponding to the
Weighted Average Life to Maturity of the principal being redeemed (taking into
account the application of such redemption required by Section 2 of this
Twenty-Eighth Supplemental Indenture). If no maturity exactly corresponds to
such Weighted Average Life to Maturity, yields for the two published maturities
most closely corresponding to such Weighted Average Life to Maturity shall be
calculated pursuant to the immediately preceding sentence and the Reinvestment
Rate shall be interpolated or extrapolated from such yields on a straight-line
basis, rounding in each of such relevant periods to the nearest month. For the
purposes of calculating the Reinvestment Rate, the most recent Statistical
Release published prior to the date of determination of the premium hereunder
shall be used.
 
     'Statistical Release' shall mean the statistical release designated
'H.15(519)' or any successor publication which is published weekly by the
Federal Reserve System and which establishes yields on actively traded U.S.
Government Securities adjusted to constant maturities or, if such statistical
release is not published at the time of any determination hereunder, then such
other reasonably comparable index which shall be designated by the holders of
66 2/3% in aggregate principal amount of the outstanding Bonds being redeemed.
 
     'Weighted Average Life to Maturity' of the principal amount of Bonds being
redeemed shall mean, as of the time of any determination thereof, the number of
years obtained by dividing the then Remaining Dollar-Years of the principal of
the Bonds being redeemed by the aggregate amount of such principal. The term
'Remaining Dollar-Years' of any such principal being redeemed shall mean the
amount obtained by (i) multiplying (1) the amount by which each required
repayment (including repayment at maturity) shall be reduced as a result of the
redemption of such principal being redeemed (which redemption shall be applied

                             REVOLVING CREDIT LOANS
 
     Section 3.01. The Bank's Obligation to Make Revolving Loans.   Subject to
the terms and conditions of this Agreement, and relying upon the representations
and warranties herein set forth, each Bank severally agrees to make revolving
credit loans ('Revolving Credit Loans') to the Borrower at any time or from time
to time on or after the date hereof to, but not including, the Revolving Credit
Commitment Termination Date in an aggregate principal amount not to exceed at
any one time such Bank's Revolving Credit Commitment. Within such limits of time
and amount and subject to the other provisions of this Agreement, the Borrower
may borrow, repay and reborrow pursuant to this Section 3.01; provided, however,
that each Revolving Credit Loan shall be in the minimum amount of (i) $100,000,

Alternative
 
                                       8
<PAGE>
or the Prime Rate Alternative, (ii) $500,000, with respect to any Revolving
Credit Loan bearing interest at the CD Rate Alternative or Euro-Rate Alternative
and (iii) $2,000,000, with respect to any Revolving Credit Loan bearing interest
at the As-Offered Rate Alternative. All Revolving Credit Loans shall be
evidenced by the Revolving Credit Notes.
 
     Section 3.02. Nature of Banks' Obligations with Respect to Revolving Credit
Loans.  (a) Each Bank shall be obligated to participate in each request for
Revolving Credit Loans pursuant to Section 3.03 hereof in accordance with its
Ratable Share. The aggregate of each Bank's Revolving Credit Loans outstanding
hereunder to the Borrower at any time shall never exceed its Revolving Credit
Commitment as the same may be amended from time to time. The obligations of each
Bank hereunder are several and not joint. The failure of any Bank to perform its
obligations hereunder shall not affect the obligations of the Borrower to any
other party nor shall any other party be liable for the failure of such Bank to
perform its obligations hereunder. The Banks shall have no obligation to make
Revolving Credit Loans hereunder on or after the Revolving Credit Commitment
Termination Date.
 
     (b) In the event any Bank is unable to fund all or a portion of its Ratable
Share of a Revolving Credit Loan due to it exceeding its Commitment and such
failure to fund was a result of it being awarded an As-Offered Rate Revolving
Credit Loan (which was funded) then the remaining unfunded portion of such
Revolving Credit Loan shall be funded by the remaining Banks that have unused
Commitments hereunder based on a calculation which reflects a gross-up of each
remaining Banks respective Commitment in relative proportion to their respective
percentages of Commitments at such time. Such calculation by Agent shall be
conclusive and binding upon each Bank absent manifest error.
 
     Section 3.03. Making the Loans.  (a) Subject to Section 3.03(b) below,
whenever the Borrower desires that the Banks make a Revolving Credit Loan, the

information:
 
          (i) The proposed Borrowing Date;
 
          (ii) The total principal amount of such Revolving Credit Loan, which
     shall be the sum of the principal amounts selected pursuant to subsection
     (a) (iii) of this Section 3.03;
 
          (iii) The Rate Alternative or Alternatives selected in accordance with
     Section 4.02 hereof and the principal amounts selected in accordance with

     Portion, As-Offered Rate Portion and each Funding Segment of the CD Rate
     Portion, the Euro-Rate Portion, and the As-Offered Rate Portion, as the
     case may be, of such Revolving Credit Loan; and
 
          (iv) With respect to each such Funding Segment, the Interest Period

Upon receipt of such Standard Notice the Agent's Loan Administration Department

Borrower of the As-Offered Rate of each Bank. If the As-Offered Rate Alternative

ascending rates until the amount of Borrower's funding needs are satisfied. In
no case shall requests for Revolving Credit Loans bearing interest at an
As-Offered Rate be less than $2,000,000. Upon acceptance by the Borrower of a
Bank's or Banks' bid, as the case may be, and funding by the Bank or Banks, as
the case may be, such Revolving Credit Loan shall be deemed to be made by such
Bank or Banks and not by the Banks pro rata.

prepayments of the outstanding balance of the Revolving Credit Loans shall be

determination the Banks shall use its best efforts to minimize the costs and
expense for which the Banks may be entitled to compensation under Section 3.08

Increased Costs or Reduced Return Resulting From Taxes, Reserves, Capital
Adequacy Requirements, Expenses, Etc. If any Law or guideline or interpretation
or application thereof by any Official Body charged with the interpretation or
administration thereof or compliance with any request or directive of any
Official Body (whether or not having the force of law) now existing or hereafter
adopted:
 
          (i) subjects any Bank to any tax or changes the basis of taxation with
     respect to this Agreement, the Notes, the Revolving Credit Loans or

     deposit or similar requirement against credits or commitments to extend

cost to, reduce the income receivable by, or impose any expense (including loss
of margin) upon any Bank with respect to this Agreement, the Notes or the
making, maintenance or funding of any part of the Revolving Credit Loans (or, in
the case of any capital adequacy or similar requirement, to have the effect of
reducing the rate of return on any Bank's capital, taking into consideration
such Bank's policies with respect to capital adequacy) by an amount which such
Bank deems to be material (such Bank being deemed for this purpose to have made,
maintained or funded the Federal Funds Rate Portion and As-Offered Rate Portion
and each Funding Segment of the CD Rate Portion and the Euro-Rate Portion from a
Corresponding Source of Funds), such Bank shall from time to time notify the
Borrower of the amount determined in good faith (using any averaging and
attribution methods) by such Bank to be necessary to compensate such Bank for
such increase, reduction or imposition provided that if any of the foregoing
results in retroactive treatment the Borrower shall only be obligated to
compensate such Bank for such increase, reduction or imposition retroactively up
to one year. Such amount shall be due and payable by the Borrower to such Bank
sixty (60) Business Days after such notice is given. Such Bank agrees that it

     Segment of the CD Rate Portion, the Euro-Rate Portion or the As-Offered
     Rate Portion on a day other than the last day of the corresponding Interest
     Period (whether or not such payment, prepayment or conversion is mandatory
     or automatic and whether or not such payment or prepayment is then due),
 
          (ii) attempt by the Borrower to revoke (expressly, by later
     inconsistent notices or otherwise) in whole or part any notice stated
     herein to be irrevocable (any Bank having in its sole discretion the
     options (a) to give effect to such attempted revocation and obtain
     indemnity under this Section 3.08(b) or (b) to treat such attempted
     revocation as having no force or effect, as if never made), or
 
          (iii) default by the Borrower in the performance or observance of any
     covenant or condition contained in this Agreement or the Notes, including
     without limitation any failure of the Borrower
 
                                       11
<PAGE>
     to pay when due (by acceleration or otherwise) any principal, interest,
     Commitment Fee or any other amount due hereunder or under the Notes.

time notify the Borrower of the amount determined in good faith by such Bank to
be necessary to indemnify such Bank for such loss or expense (such Bank being
deemed for this purpose to have made, maintained or funded the Federal Funds
Rate Portion and As-Offered Rate Portion and each Funding Segment of the CD Rate
Portion and the Euro-Rate Portion from a Corresponding Source of Funds). Such
amount shall be due and payable by the Borrower to such Bank ten Business Days
after such notice is given.
 
     (c) In the event the Borrower is required to make payment under Section
3.08(a) hereof, the Borrower in its sole discretion may require that such
Bank(s) and its respective Revolving Credit Commitment be replaced in its
entirety; first, by the remaining Banks hereunder (if such remaining Banks so
agree) and second, to any other bank or financial institution reasonably
acceptable to each of the other Banks.
 
     Section 3.09. Effect of Payments or Prepayments.  Any payment or prepayment
of the outstanding balance of the Revolving Credit Loans as provided in Section
3.06 hereof prior to the Revolving Credit Commitment Termination Date shall
restore the availability of the Revolving Credit Commitment to the extent of
such payment or prepayment, unless the Revolving Credit Commitments have been
terminated by the Borrower pursuant to Section 2.03 or by any Bank pursuant to
Section 8.01 on or before the date of such payment or prepayment.
 
     Section 3.10. Form of Notice.  Any notice from the Borrower to the Agent or
from the Agent to the Borrower required or permitted by this Article III shall
be sent by telephone confirmed by first class mail or fax (which shall be
effective when telephoned), by fax (which shall be effective when received) or
by first-class or first-class express mail (which shall be effective two
Business Days after such notice is deposited), in all cases with charges
prepaid.
 
     Section 3.11. Funding by Euro-Rate Funding Office.  Each Bank shall have
the right from time to time, prospectively or retrospectively, without notice to
the Borrower, to deem any branch, subsidiary or affiliate of such Bank to have
made, maintained or funded any Euro-Rate Portion at any time. Any branch,
subsidiary or affiliate so deemed shall be known as a 'Euro-Rate Funding
Office.' Each Bank shall deem any Euro-Rate Portion or the funding therefor to
have been transferred to a different Euro-Rate Funding Office if such transfer
would lessen compensation payable by the Borrower under Section 3.08(a) hereof,
and if such Bank determines in its sole discretion that such transfer would be
practicable and would not have a material adverse effect on such Revolving
Credit Loan, such Bank or any Euro-Rate Funding Office (it being assumed for
purposes of such determination that each Euro-Rate Portion is actually made or
maintained by or funded through the corresponding Euro-Rate Funding Office).
 
                                   ARTICLE IV
                                    INTEREST
 
     Section 4.01. Accrual of Interest on Revolving Loans.  Each Revolving
Credit Loan shall accrue interest at the Rate Alternative applicable to such
Revolving Credit Loan in accordance with this Article IV. Interest on each
Revolving Credit Loan bearing interest at the Prime Rate Alternative or the
Federal Funds Rate Alternative shall accrue interest subject to the provisions
of this Article IV, during the time such Revolving Credit Loan is outstanding.
Interest on each Revolving Credit Loan bearing interest at the CD Rate
Alternative, the Euro-Rate Alternative or the As-Offered Rate Alternative shall
accrue during the Interest Period applicable to such Revolving Credit Loan in
accordance with this Article IV.
 
     Section 4.02. Rate Alternatives.  The unpaid principal amount of the
Revolving Credit Loans shall bear interest for each day until due on one or more
bases selected by the Borrower from among the Rate Alternatives set forth below,
it being understood that subject to the provisions of this
 
                                       12
<PAGE>
Agreement, the Borrower may select different Rate Alternatives to apply
simultaneously to different parts of the Revolving Credit Loans and may select
different Funding Segments to apply simultaneously to different parts of the CD
Rate Portion, the Euro-Rate Portion or the As-Offered Rate Portion:
 
     (a) Prime Rate Alternative:  A rate per annum for each day equal to the
Prime Rate for such day, such interest rate to change automatically and be
effective from time to time, effective as of the effective date of each change
in the Prime Rate without notice to the Borrower. 'Prime Rate', as used herein,
means the interest rate per annum announced by the Agent from time to time as
its prime rate, and is used by the Agent as a reference rate with respect to
different interest rates charged to borrowers. The determination and statement
of the 'Prime Rate' shall not in any way preclude the Agent from making loans to
other borrowers at rates which are higher or lower than the Prime Rate.
 
     (b) Federal Funds Rate Alternative:  A rate per annum for each day equal to
the Federal Funds Effective Rate for such day plus .75%, such interest rate to
change automatically and be effective from time to time, effective as of the
date of each change in the Federal Funds Effective Rate without notice to the
Borrower. 'Federal Funds Effective Rate' for any day, as used herein, shall mean
the rate per annum (rounded upward to the nearest 1/100 of 1%) announced by the
Federal Reserve Bank of New York (or any successor) on such day as being the
weighted average of the rates on overnight Federal funds transactions arranged
by Federal funds brokers on the previous trading day, as computed and announced
by such Federal Reserve Bank (or any successor) in substantially the same manner
as such Federal Reserve Bank computes and announces the weighted average it
refers to as the 'Federal Funds Effective Rate' as of the date of this
Agreement; provided, if such Federal Reserve Bank (or its successor) does not
announce such rate on any day, the 'Federal Funds Effective Rate' for such day
shall be the Federal Funds Effective Rate for the last day on which such rate
was announced.
 
     (c) CD Rate Alternative:  A rate per annum for each day equal to the CD
Rate for such day plus .375%. 'CD Rate' for any day, as used herein, shall mean
for each Funding Segment of the CD Rate Portion corresponding to a proposed or
existing CD Rate Interest Period the rate per annum determined by the Agent by
adding
 
          (i) the rate per annum obtained by dividing (the resulting quotient to
     be rounded upward to the nearest 1/100 of 1%) (a) the rate of interest
     (which shall be the same for each day in such CD Rate Interest Period)
     determined in good faith by the Agent in accordance with its usual
     procedures to be the average of the secondary market bid rates at or about
     11:00 o'clock a.m., Eastern Time, on the first day of such CD Rate Interest
     Period by dealers of recognized standing in negotiable certificates of
     deposit for the purchase at face value of negotiable certificates of
     deposit of major money center banks for delivery on such day in amounts
     comparable to such Funding Segment and having maturities comparable to such
     CD Rate Interest Period by (b) a number equal to 1.00 minus the CD Rate
     Reserve Percentage and
 
          (ii) the Assessment Rate.
 
          The 'CD Rate' may also be expressed by the following formula:
 
<TABLE>
<S>            <C>                                                        <C>
               [average of the secondary market                  ]
               [bid rates determined by the Agent                ]
CD Rate =      [per Subsection (i)(a)                            ]         + Assessment Rate
               [1.00 - CD Rate Reserve Percentage                ]
</TABLE>
 
     The 'CD Rate Reserve Percentage' for any day is the maximum effective
percentage (expressed as a decimal, rounded upward to the nearest 1/100 of 1%),
as determined in good faith by the Agent, which is in effect on such day as
prescribed by the Board of Governors of the Federal Reserve System (or any
successor) for determining the reserve requirements (including without
limitation supplemental, marginal and emergency reserve requirements) for a
member bank of such System in respect of nonpersonal time deposits in Dollars in
the United States. The CD Rate shall be adjusted automatically and effective as
of the effective date of each change in the CD Rate Reserve Percentage without
notice to the Borrower.
 
                                       13
<PAGE>
     The 'Assessment Rate' for any day is the rate per annum (rounded upward to
the nearest 1/100 of 1%) determined in good faith by the Agent in accordance
with its usual procedures to be the maximum effective assessment rate per annum
payable by a bank insured by the Federal Deposit Insurance Corporation (or any
successor) for such day for insurance on Dollar time deposits, exclusive of any
credit allowed against such annual assessment on account of assessment payments
made or to be made by such bank. The CD Rate shall be adjusted automatically and
effective as of the effective date of each change in the Assessment Rate without
notice to the Borrower.
 
     The Agent shall give prompt notice to the Borrower of the CD Rate so
determined or adjusted.
 
     (d) Euro-Rate Alternative: A rate per annum for each day equal to the
Euro-Rate for such day plus .25%. 'Euro-Rate' for any day, as used herein, shall
mean for each Funding Segment of the Euro-Rate Portion corresponding to a
proposed or existing Euro-Rate Interest Period the rate per annum determined by
the Agent by dividing (the resulting quotient to be rounded upward to the
nearest 1/100 of 1%) (i) the rate of interest (which shall be the same for each
day in such Euro-Rate Interest Period) determined in good faith by the Agent in
accordance with its usual procedures to be the average of the rates per annum
for deposits in Dollars offered to major money center banks in the London
interbank market at approximately 11:00 o'clock a.m., London time, two London
Business Days prior to the first day of such Euro-Rate Interest Period for
delivery on the first day of such Euro-Rate Interest Period in amounts
comparable to such Funding Segment and having maturities comparable to such
Euro-Rate Interest Period by (ii) a number equal to 1.00 minus the Euro-Rate
Reserve Percentage.
 
     The 'Euro-Rate' may also be expressed by the following formula:
 
<TABLE>
<S>           <C>
              [average of the rates offered to major money  ]
              [center banks in the London interbank market  ]
Euro-Rate     [determined by the Agent per subsection (i)   ]
              [1.00 - Euro-Rate Reserve Percentage          ]
</TABLE>
 
     The 'Euro-Rate Reserve Percentage' for any day is the maximum effective
percentage (expressed as a decimal fraction, rounded upward to the nearest 1/100
of 1%), as determined in good faith by the Agent, which is in effect on such day
as prescribed by the Board of Governors of the Federal Reserve System (or any
successor) for determining the reserve requirements (including, without
limitation, supplemental, marginal and emergency reserve requirements) with
respect to eurocurrency funding (currently referred to as 'Eurocurrency
liabilities') of a member bank in such System. The Euro-Rate shall be adjusted
automatically and be effective as of the effective date of each change in the
Euro-Rate Reserve Percentage without notice to the Borrower.
 
     The Agent shall give prompt notice to the Borrower of the Euro-Rate so
determined or adjusted.
 
     (e) As-Offered Rate Alternative: A rate per annum for each day equal to the
As-Offered Rate for such day. As-Offered Rate for any day, as used herein, shall
mean for each Funding Segment of the As-Offered Interest Period the rate per
annum quoted by such Bank as its as-offered rate for such period.
 
     The Agent's Loan Administration Department upon Borrower's request shall
solicit bids from each Bank. Borrower shall accept bids in order of ascending
rates until Borrower's funding needs are satisfied, as more particularly
described in Sections 3.03(b) and 4.04(b).
 
     Section 4.03. Interest Periods.  At any time when the Borrower shall
select, convert to or renew the CD Rate Alternative, the Euro-Rate Alternative
or the As-Offered Rate Alternative to apply to any
 
                                       14
<PAGE>
part of the Revolving Credit Loans, it shall fix one or more periods during
which each such Rate Alternative shall apply, such periods (the 'Interest
Periods') being set forth in the chart below:
 
<TABLE>
<CAPTION>
RATE ALTERNATIVE                                                 AVAILABLE INTEREST PERIODS

As-Offered Rate Alternative                 One through thirty days ('As-Offered Rate Interest Period');
</TABLE>
 
provided, that:
 
          (a) Each CD Rate Interest Period which would otherwise end on a day
     which is not a Business Day shall be extended to the next succeeding
     Business Day;
 
          (b) Each Euro-Rate Interest Period shall begin on a London Business
     Day, and the duration of each Euro-Rate Interest Period shall be determined
     in accordance with the definition of the term 'month' herein; and
 
          (c) The Borrower may not fix an Interest Period that would end after
     the Revolving Credit Commitment Termination Date.
 
     Section 4.04. Conversion or Renewal of Rate Alternatives.
 
     (a) Conversion or Renewal.  Subject to Section 4.04(b) hereof and provided
no default or Event of Default exists at such time the Borrower may convert any
part of the Revolving Credit Loans from any Rate Alternative or Alternatives to
one or more different Rate Alternatives and may renew the CD Rate Alternative,
the Euro-Rate Alternative or the As-Offered Rate Alternative as to any Funding
Segment of the CD Rate Portion, the Euro-Rate Portion or the As-Offered Rate
Portion:
 
          (i) at any time with respect to conversion from the Prime Rate
     Alternative or the Federal Funds Rate Alternative,
 
          (ii) at the expiration of any Interest Period with respect to
     conversions from or renewals of the CD Rate Alternative, the Euro-Rate
     Alternative or the As-Offered Rate Alternative, as the case may be, as to
     the Funding Segment corresponding to such expiring Interest Period, or
 
          (iii) on the date specified in a notice by the Agent pursuant to
     Section 4.07(b) hereof with respect to conversions from the CD Rate
     Alternative, the Euro-Rate Alternative or the As-Offered Rate Alternative,
     as the case may be.
 
     Whenever the Borrower desires to convert or renew any Rate Alternative or
Alternatives the Borrower shall provide to the Agent Standard Notice setting
forth the following information:
 
          (A) The Borrowing Date on which the proposed conversion or renewal is
     to be made;
 
          (B) The principal amounts selected in accordance with Section 3.01
     hereof of the Prime Rate Portion, the Federal Funds Rate Portion and each

     renewed;
 
          (C) In the case of conversions, the Rate Alternative or Alternatives
     selected in accordance with Section 4.02 hereof and the principal amounts
     selected in accordance with Section 3.01 of the Prime Rate Portion, the
     Federal Funds Rate Portion and each Funding Segment of the CD Rate Portion,
     the Euro-Rate Portion and the As-Offered Rate Portion, as the case may be,
     to be converted to; and
 
          (D) With respect to each Funding Segment to be converted to or
     renewed, the Interest Period selected in accordance with Section 4.03
     hereof to apply to such Funding Segment.
 
                                       15
<PAGE>
Standard Notice having been so provided, after the date specified in such
Standard Notice interest shall be calculated upon the principal amount of the
Revolving Credit Loans as so converted or renewed.
 
     (b) As-Offered Rate.  Whenever the Borrower desires to convert to an
As-Offered Rate Alternative or renew a Revolving Credit Loan bearing interest at
an As-Offered Rate Alternative, the Borrower will provide Standard Notice to the
Agent's Loan Administration Department, Attention: Ms. Flossie Bowers, setting
forth the information described in Section 4.04(a) above. Upon receipt of such
Standard Notice, the Agent's Loan Administration Department will solicit bids
from the Banks and will notify the Borrower of the As-Offered Rate of each Bank.
If the As-Offered Rate Alternative is selected by the Borrower, Borrower agrees
to accept all bids in the order of ascending rates until the amount of
Borrower's funding needs are satisfied. In no event shall requests for Revolving
Credit Loans bearing interest at the As-Offered Rate be less than $2,000,000.
Upon acceptance by the Borrower of a Bank's or Banks' bid, as the case may be,
and the funding by the Bank or Banks such Revolving Credit Loan shall be deemed
to be made by such Bank or Banks and not by the Banks pro rata.
 
     (c) Failure to Convert or Renew. Absent due notice from the Borrower of
conversion or renewal in the circumstances described in Section 4.04(a)(ii)
hereof, any part of the CD Rate Portion, Euro-Rate Portion or As-Offered Rate
Portion for which such notice is not received shall be converted automatically
to the Prime Rate Alternative on the last day of the expiring Interest Period.
 
     Section 4.05. Calculation of Accrued Interest.  The accrual of interest
under this Article IV shall be computed for the actual number of days elapsed,
and on the basis of a year of 360 days (on a 365/360 day basis except that in a
leap year the computation shall be on a 366/360 days basis).
 
     Section 4.06. Payment of Interest. Interest on each Revolving Credit Loan
accrued in accordance with this Article IV shall be due and payable in
accordance with Article III hereof.
 
     Section 4.07. Unavailability of Certain Loans.  (a) Federal Funds Effective
Rate Unascertainable; Impracticability. If at any time the Banks shall have
determined in good faith that:
 
          (i) the Federal Reserve Bank of New York (or its successor) shall not
     have announced a Federal Funds Effective Rate on any day other than a
     Saturday, Sunday, public holiday or other day on which no Federal Funds
     Effective Rate would normally be announced under the practices of such
     Federal Reserve Bank as of the date hereof, at the time when the Federal
     Funds Effective Rate on such day would normally be announced under the
     practices of such Federal Reserve Bank as of the date hereof,
 
          (ii) the effective cost to any Bank of funding any proposed or
     existing Federal Funds Rate Portion of the Revolving Credit Loans from a
     Corresponding Source of Funds shall exceed the Federal Funds Effective
     Rate, or
 
          (iii) the making, maintenance or funding of any part of the Federal
     Funds Rate Portion of the Revolving Credit Loans has been made impractical
     or unlawful by compliance with any Bank in good faith with any Law or
     guideline or interpretation or administration thereof by any Official Body
     charged with the interpretation or administration thereof or with any
     request or directive of any such Official Body (whether or not having the
     force of law);
 
then, and in any such event, interest on the Federal Funds Rate Portion of the
Revolving Credit Loans shall be at the Prime Rate Alternative until such Bank
shall have later determined in good faith that the circumstances giving rise to
such previous determination no longer exist. If and when the Banks shall make
such a later determination, interest on the Federal Funds Rate Portion of the
Revolving Credit Loans shall again be at the Federal Funds Rate Alternative.
 
     The Banks shall notify the Agent (and the Agent shall notify the Borrower)
forthwith of any determination under this Section 4.07(a). The Borrower may
convert any part of the Federal Funds Rate Portion of the Revolving Credit Loans
to another Alternative or Alternatives in accordance with the provisions of this
Agreement during the continuance of any condition described in this Section
4.07(a). The Borrower may select or convert any part of the Revolving Credit
Loans to the Federal
 
                                       16
<PAGE>
Funds Rate Alternative in accordance with the provisions of this Agreement
during the continuance of any condition described in this Section 4.07(a),
although during the continuance of such condition interest on such part of the
Revolving Credit Loans shall be at the Prime Rate Alternative in accordance with
this Section 4.07(a).
 
     (b) CD Rate or Euro-Rate Unascertainable; Impracticability. If,
 
        (i) on any date on which a CD Rate or a Euro-Rate would otherwise be set
any Bank shall have in good faith determined that:
 
             (A) adequate and reasonable means do not exist for ascertaining
        such CD Rate or Euro-Rate,
 
             (B) a contingency has occurred which materially and adversely
        affects the ability of any Bank to obtain funds in the secondary market
        for negotiable certificates of deposit maintained by dealers of
        recognized standing or the interbank eurodollar market, as the case may
        be, or
 
             (C) the effective cost to any Bank of funding a proposed Funding
        Segment of the CD Rate Portion or the Euro-Rate Portion from a
        Corresponding Source of Funds shall exceed the CD Rate or the Euro-Rate,
        as the case may be, applicable to such Funding Segment, or
 
          (ii) at any time any Bank shall have determined in good faith that the
     making, maintenance or funding of any part of the CD Rate Portion or the
     Euro-Rate Portion has been made impracticable or unlawful by compliance by
     any Bank in good faith with any Law or guideline or interpretation or
     administration thereof by any Official Body charged with the interpretation
     or administration thereof or with any request or directive of any such
     Official Body (whether or not having the force of law);
 
then, and in any such event, the Agent shall notify the Borrower of such
determination. Upon such date as shall be specified in such notice (which shall
not be earlier than the date such notice is given) the obligation of the Banks
to allow the Borrower to select, convert to or renew the CD Rate Alternative or
the Euro-Rate Alternative, as the case may be, shall be suspended until such
Bank shall have later notified the Borrower of the Bank's determination in good
faith that the circumstances giving rise to such previous determination no
longer exist.
 
     If any Bank notifies the Borrower of a determination under subsection (ii)
of this Section 4.07(b) the Borrower shall, as to the CD Rate Portion or the
Euro-Rate Portion, as the case may be, on the date specified in such notice
either convert such Portion to another Rate Alternative or Alternatives in
accordance with Section 4.02 hereof or prepay such Portion in accordance with
Section 3.06(b) hereof. Absent due notice from the Borrower of conversion or
prepayment the CD Rate Portion or the Euro-Rate Portion, as the case may be,
automatically shall be converted to the Prime Rate Alternative upon such
specified date.
 
     If at the time any Bank makes a determination under subsection (i) or (ii)
of this Section 4.07(b) and the Borrower has previously notified the Agent that
it wishes to select, convert to or renew the CD Rate Alternative or the
Euro-Rate Alternative, as the case may be, but such Alternative has not yet gone
into effect, such notification shall be deemed to provide for selection of,
conversion to or renewal of the Prime Rate Alternative instead of the CD Rate
Alternative or the Euro-Rate Alternative, as the case may be.
 
     (c) In the event the Borrower is required to make payment under Sections
4.07(a) and 4.07(b) hereof, the Borrower in its sole discretion may require that
such Bank(s) and its respective Revolving Credit Commitment be replaced in its
entirety; first, by the remaining Banks hereunder (if such remaining Banks so
agree) and second, to any other bank or financial institution, reasonably
acceptable to each of the other Banks.

     Section 4.08. Maximum Interest.  No provision of this Agreement or any
Revolving Loan Note shall require the payment or permit the collection of
interest in excess of the highest rate permitted by applicable law.
 
     Section 4.09. Form of Notice.  Any notice from the Borrower to the Agent or
from the Agent to the Borrower required or permitted by this Article IV shall be
sent by telephone confirmed by first class mail or fax (which shall be effective
when telephoned), by fax (which shall be effective when received) or by
first-class or first-class express mail (which shall be effective two Business
Days after such notice is deposited), in all cases with charges prepaid.
 
     Section 4.10. Pro-Rata Treatment of Banks; Payments.  (a) Each borrowing,
and each selection of, conversion to or renewal of any Rate Alternative and each
payment or prepayment by the Borrower with respect to principal, interest,
Commitment Fee, or other fees or amounts due from Borrower hereunder to the
Banks with respect to the Revolving Credit Loans, shall (except as provided in
Sections 3.02(b), 3.03(b) and 4.04(b), Section 4.07 [Unavailability CD Rate or
Euro-Rate Unascertainable] or Section 2.02(b) [Fees], hereof) be made in
proportion to Revolving Credit Loans outstanding from each Bank and if no such
Revolving Credit Loans are then outstanding, in proportion to the Ratable Share
of each Bank.
 
     In instances where a Revolving Credit Loan is funded pursuant to Section
3.02(b) hereof, any payments and/or prepayments shall be applied in the
proportions in which such Revolving Credit Loan was originally funded.
 
     (b) All payments and prepayments received by Agent in respect of principal,
interest, Commitment Fees, or other fees or amounts due from the Borrower to the
Banks hereunder shall be promptly distributed by the Agent to the Banks in
immediately available funds; provided, that, in the event payments are received
by 11:00 a.m. (Philadelphia time) by the Agent with respect to the Loans and
such payments are not distributed to the Banks on the same day received by the
Agent, the Agent shall pay the Banks the Federal Funds Effective Rate with
respect to the amount of such payments for each day held by the Agent and not
distributed to the Banks.

guarantees or other contingent liabilities of the Borrower exceeding $500,000 in

Form) including all attachments thereto as filed with the Internal Revenue
Service for each Plan has been provided to the Agent and fairly presents the
funding status of each Plan. There has been no material deterioration in any
Plan's funding status since the date of such Annual Report. The Borrower has

Multiemployer Plan. The PBGC premiums and contributions required to meet the
minimum funding requirements of ERISA and the Code for all Plans for the last
five plan years prior to the date hereof have not exceeded $2,500,000 on an
annual basis. The amount by which the accumulated benefit obligation exceeds the
fair value of the Plan assets, as certified to by the Plan's actuary, for any
Plan for the last plan year ended prior to the date hereof for which an
actuarial report containing such a calculation has been completed did not exceed
$10,000 and for all Plans for such plan year did not exceed $20,000. The

quasi-governmental authority or agency or any other Person concerning any
material non-compliance with any Environmental Law, including those that relate

Reserve System (12 C.F.R. 207, 221), and the Borrower does not have any present
intention of acquiring any margin security.
 
     Section 5.15. No Untrue Statements.  To the best of the Borrower's
knowledge, the Loan Documents nor any other document, certificate or statement
furnished or to be furnished by the Borrower or by any other party to the Banks
in connection herewith contains, or at the time of delivery will contain, any
untrue statement of a material fact or omits or will omit to state a material

and to have been signed, sent or made by the proper person or persons, and upon
the advice and opinions of counsel and other professional advisers selected by
the Agent. The Agent shall be fully justified in failing or refusing to take any
action hereunder unless it shall first be indemnified to its satisfaction by the
Banks against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action.
 
     Section 10.09. Notice of Default.  The Agent shall not be deemed to have

Revolving Credit Commitments and the Revolving Credit Loans made by it, the
Agent shall have the same rights and powers hereunder as any other Bank and may

capacity. Mellon Bank, N.A. and its affiliates and each of the Banks and their
respective affiliates may, without liability, except as prohibited herein, make
Revolving Credit Loans to, accept deposits from, discount drafts for, act as
trustee under indentures of, and generally engage in any kind of banking or
trust business with, the Borrower and its affiliates, in the case of the Agent,
as though it were not acting as Agent hereunder and in the case of each Bank as
though such Bank were not a Bank hereunder.
 
     Section 10.12. Holders of Revolving Credit Notes.  The Agent may deem and
treat any payee of any Revolving Credit Note as the owner thereof for all
purposes hereof unless and until written notice of the assignment or transfer
thereof shall have been filed with the Agent. Any request, authority or consent

consent is the holder of any Revolving Credit Note shall be conclusive and
binding on any subsequent holder,

respect to all amounts received by any Bank or any such holder for application
on any obligation hereunder or under any Revolving Credit Note or under any
other Loan Document or under any such participation, whether received by
voluntary payment, by realization upon security, by the exercise of the right of
set-off or banker's lien, by counterclaim or by any other non-pro rata source,
equitable adjustment will be made in the manner stated in the following sentence
so that, in effect, all such excess amounts will be shared ratably among the
Banks and such holders in proportion to their interests in payments under the
Revolving Credit Notes, except as otherwise provided in Sections 4.04 or 4.07
hereof. The Banks or any such holder receiving any such amount shall purchase
for cash from each of the other Banks an interest in such Bank's Revolving
Credit Loans in such amount as shall result in a ratable participation by the
Banks and each such holder in the aggregate unpaid amount under the Revolving
Credit Notes, provided that if all or any portion of such excess amount is
thereafter recovered from the Bank or the holder making such purchase, such
purchase shall be rescinded and the purchase price restored to the extent of
such recovery, together with interest or other amounts, if any, required by Law
(including court order) to be paid by the Bank or the holder making such
purchase.

from among the Banks a successor agent for the Banks within the thirty (30) day
period following the Agent's notice to the Banks of its resignation, or (b) the
Agent shall appoint, with the consent of the Borrower, such consent not to be
unreasonably withheld, a successor agent who shall serve as Agent until such
time as the Majority Banks appoint, a successor agent. Upon its appointment

to the rights, powers and duties of the Agent and the term 'Agent' shall mean
such successor agent, effective upon its appointment, and the former Agent's
rights, powers and duties as Agent shall be terminated without any other or
further act or deed on the part of such former Agent or any of the parties to
this Agreement. After the resignation of any Agent hereunder, the provisions of
this Article X shall inure to the benefit of such former Agent and such former
Agent shall not by reason of such resignation be deemed to be released from
liability for any actions taken or not taken by it while it was an Agent under
this Agreement.
 
     Section 10.15. Availability of Funds.  Unless the Agent shall have been
notified by a Bank prior to the date upon which a Loan is to be made that such
Bank does not intend to make available to the Agent such Bank's portion of such
Loan, the Agent may assume that such Bank has made or will make such proceeds
available to the Agent on such date and the Agent may, in reliance upon such
assumption (but shall not be obligated to), make available to the Borrower a
corresponding amount. If such corresponding amount is not in fact made available
to the Agent by such Bank, the Agent shall be entitled to recover such amount on
demand from such Bank (or, if such Bank fails to pay such amount forthwith upon
such demand from the Borrower) together with interest thereon, in respect of
each day during the period commencing on the date such amount was made available
to the Borrower and ending on the date the Agent recovers such amount, at a rate
per annum equal to the applicable interest rate in respect of the Loan.
 
     Section 10.16. Calculations.  In the absence of gross negligence or willful
misconduct, the Agent shall not be liable for any error in computing the amount
payable to any Bank whether in respect of the Loans, fees or any other amounts
due to the Banks under this Agreement. In the event an error in computing any
amount payable to any Bank is made, the Agent, the Borrower and each affected
Bank shall, forthwith upon discovery of such error, make such adjustments as
shall be required to correct such error, and any compensation thereof will be
calculated at the Federal Funds Effective Rate.

     Section 10.17. Beneficiaries.  The provisions of this Article X are for the
benefit of the Agent and the Banks, and except as expressly provided herein, the
Borrower shall not have any rights to rely on or enforce any of the provisions
hereof. In performing its functions and duties under this Agreement, the Agent
shall act solely as agent of the Banks and does not assume and shall not be
deemed to have assumed any obligation toward or relationship of agency or trust
with or for the Borrower.
 
                                   ARTICLE XI
                                 MISCELLANEOUS
 
     Section 11.01. Modifications, Amendments or Waivers.  With the written
consent of the Majority Banks, the Agent, acting on behalf of all the Banks, and
the Borrower may from time to time enter into written agreements amending or
changing any provision of this Agreement or any other Loan Document or the
rights of the Banks or the Borrower hereunder or thereunder, or may grant
written waivers or consents to a departure from the due performance of the
obligations of the Borrower hereunder or thereunder. Any such agreement, waiver
or consent made with such written consent shall be effective to bind all the
Banks; provided, that, without the written consent of all the Banks, no such
agreement, waiver or consent may be made which will:
 
     (a) Reduce the amount of the Commitment Fee or any other fees payable to
any Bank hereunder, extend the Revolving Credit Commitment Termination Date,
increase the Commitment amount with respect to any Bank, or amend Sections [4.10
(Pro Rata Treatment of Banks)], [10.06] (Exculpatory provisions) and [10.13]
(Equalization of Banks) hereof;
 
     (b) Whether or not any Revolving Credit Loans are outstanding, extend the
time for payment of principal or interest of any Revolving Credit Loan, or
reduce the principal amount of or the rate of interest borne by any Revolving
Credit Loan, or otherwise affect the terms of payment of the principal of or
interest of any Loan;
 
     (c) Amend this Section 11.01, change the definition of Majority Banks or
change any requirement providing for the Banks or the Majority Banks to
authorize the taking of any action hereunder; or
 
     (d) Except for sales of assets permitted herein, release any collateral or
other security (if any), for the Borrower's obligations hereunder.
 
     Section 11.02. No Waiver; Cumulative Remedies. No failure or delay on the
part of the Agent or any Bank in exercising any right, power or remedy hereunder
shall operate as a waiver thereof; nor shall any single or partial exercise of
any such right, power or remedy preclude any other or further exercise thereof
or the exercise of any other right, power or remedy hereunder. The remedies
herein provided are cumulative and not exclusive of any remedies provided by
Law.
 
     Section 11.03. Costs, Expenses and Attorneys' Fees. If the transactions
contemplated by this Agreement and the other Loan Documents are not fully
consummated due to the fault of the Borrower, the Borrower shall promptly pay
(or reimburse, as the Agent may elect) all reasonable costs and expenses which
the Agent has incurred or may hereafter incur in connection with the
negotiation, preparation, reproduction, interpretation and enforcement of this
Agreement and the other Loan Documents, the collection of all amounts due
hereunder and thereunder, and any amendment, modification, consent or waiver
which may be hereafter requested by the Borrower or otherwise required. Such
costs and expenses shall include the reasonable fees and disbursements of
counsel to the Agent, the costs of appraisal fees, searches of public records,
costs of filing and recording documents with public offices, and similar costs
and expenses incurred by the Agent. Upon the occurrence of an Event of Default,
such costs shall also include the reasonable fees of any accountants,
consultants or other professionals retained by the Agent and the Banks directly
related hereto. The Borrower's reimbursement obligations under this Section
shall survive any termination of this Agreement.
 
                                       33
<PAGE>
     Section 11.04. Governing Law.  This Agreement and the Notes shall be
governed in all respects by the law of the Commonwealth of Pennsylvania and for
all purposes shall be construed in accordance with such law.
 
     Section 11.05. Headings.  Article and Section headings used in this
Agreement are for convenience only and shall not affect the construction of this
Agreement.
 
     Section 11.06. Exhibits.  All exhibits attached hereto are hereby made a
part hereof.
 
     Section 11.07. Amendments and Waivers.  The Banks and the Borrower may from
time to time enter into agreements amending, modifying or supplementing this
Agreement or the Notes or any other documents or instruments pursuant to or in
connection herewith or changing the rights of the Banks or of the Borrower
hereunder or thereunder, and the Banks may from time to time grant waivers or
consents to a departure from the due performance of the obligations of the
Borrower hereunder or thereunder. Any such agreement, waiver or consent must be
in writing and shall be effective only to the extent specifically set forth in
such writing. In the case of any such waiver or consent relating to any
provision hereof, any Event of Default so waived or consented to shall be deemed
to be cured and not continuing, but no such waiver or consent shall extend to
any other or subsequent Event of Default or impair any right consequent thereto.
 
     Section 11.08. Successors and Assigns; Participations.  This Agreement
shall be binding upon and inure to the benefit of the Banks, the Borrower and
their respective successors and assigns, except that the Borrower may not assign
or transfer any of its rights hereunder without the prior written consent of the
Agent and Banks. Each Bank may, at its own cost, make assignments of or sell
participations in all or any part of its Revolving Credit Commitment and the
Loans made by it to one or more banks or other entities, subject to the consent
of the Borrower and the Agent with respect to any assignees, such consent not to
be unreasonably withheld, and provided that no assignment or participation shall
be made in amounts less than $5,000,000 and further provided that with respect
to any assignment each assigning Bank agrees to pay to Agent a servicing fee of
$2,000 payment on or prior to the date of assignment. In the case of an
assignment, upon receipt by the Agent of the Assignment and Assumption Agreement
in the form set forth in Exhibit 11.08 hereof and the $2,000 service fee, the
assignee shall have, to the extent of such assignment (unless otherwise provided
therein), the same rights, benefits and obligations as it would have if it had
been a signatory Bank hereunder, the Commitments in Section 2.01 and Schedule
1.01(a) shall be adjusted accordingly, and upon surrender of any Note subject to
such assignment, the Borrower shall execute and deliver a new Note to the
assignee in an amount equal to the amount of the Revolving Credit Commitment
assumed by it and a new Revolving Credit Note to the assigning Bank in an amount
equal to the Revolving Credit Commitment retained by it hereunder. In the case
of a participation, the participant shall only have the rights specified in
Section 8.01(C) (the participant's rights against such Bank in respect of such
participation to be those set forth in the agreement executed by such Bank in
favor of the participant relating to changes of the type referenced in clauses
(A), (B), or (C) under Section 11.01 hereof), all of such Bank's obligations
under this Agreement or any other Loan Document shall remain unchanged and all
amounts payable by the Borrower hereunder or thereunder shall be determined as
if such Bank had not sold such participation.
 
     Section 11.09. Records.  The unpaid principal amount of the Notes, the
unpaid interest accrued thereon, the interest rate or rates applicable to such
unpaid principal amount, the duration of such applicability, the Revolving
Credit Commitments and the accrued and unpaid Commitment Fee shall at all times
be ascertained from the records of the Agent, which shall be conclusive absent
manifest error.
 
     Section 11.10. Judicial Proceedings.  Each party to this Agreement agrees
that any suit, action or proceeding, whether claim or counterclaim, brought or
instituted by any party hereto or any successor or assign of any party, on or
with respect to this Agreement or any of the other Loan Documents or the
dealings of the parties with respect hereto, or thereto, shall be tried only by
a court and not by a jury. EACH PARTY HEREBY KNOWINGLY, VOLUNTARILY AND
INTENTIONALLY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY SUCH SUIT, ACTION OR
PROCEEDING. Further, except as otherwise provided herein, each party waives any
right it may have to claim or recover, in
 
                                       34
<PAGE>
any such suit, action or proceeding, any special, exemplary, punitive or
consequential damages or any damages other than, or in addition to, actual
damages. THE BORROWER ACKNOWLEDGES AND AGREES THAT THIS SECTION IS A SPECIFIC
AND MATERIAL ASPECT OF THIS AGREEMENT AND THAT THE BANKS WOULD NOT EXTEND CREDIT
TO THE BORROWER IF THE WAIVERS SET FORTH IN THIS SECTION WERE NOT A PART OF THIS
AGREEMENT.
 
     Section 11.11. Consent to Jurisdiction and Service of Process.  The
Borrower irrevocably appoints each and every financial or executive officer of
the Borrower as its attorneys upon whom may be served, by regular or certified
mail at the address set forth in Section [11.12] hereof, any notice, process or
pleading in any action or proceeding against it arising out of or in connection
with this Agreement or any of the other Loan Documents; and the Borrower hereby
consents that any action or proceeding against it be commenced and maintained in
any court within the Commonwealth of Pennsylvania or in the United States
District Court for the Eastern District of Pennsylvania by service of process on
any such officer; and the Borrower agrees that the courts of the Commonwealth of
Pennsylvania and the United States District Court for the Eastern District of
Pennsylvania shall have jurisdiction with respect to the subject matter hereof
and the person of the Borrower and the collateral, if any. Notwithstanding the
foregoing, the Agent and the Banks, in their absolute discretion may also
initiate proceedings in the courts of any other jurisdiction in which the
Borrower may be found or in which any of its properties may be located.
 
     Section 11.12. Notices.  All notices, requests, demands, directions and
other communications (collectively, 'notices') given to or made upon any party
hereto under the provisions of this Agreement shall be by telephone or in
writing (including telex or facsimile communication) unless otherwise expressly
permitted hereunder and shall be delivered or sent by telex or facsimile to the
respective parties at the addresses and numbers set forth under their respective
names on the signature pages hereof or in accordance with any subsequent
unrevoked written direction from any party to the others. All notices shall,
except as otherwise expressly herein provided, be effective (a) in the case of
telex or facsimile, when received, (b) in the case of hand-delivered notice,
when hand delivered, (c) in the case of telephone, when telephoned, provided,
however, that in order to be effective, telephonic notices must be confirmed in
writing no later than the next day by letter, facsimile or telex, (d) if given
by mail, four (4) days after such communication is deposited in the mails with
first class postage prepaid, return receipt requested, and (e) if given by any
other means (including by air courier), when delivered; provided, that notices
to the Agent shall not be effective until received. Any Bank giving any notice
to the Borrower shall simultaneously send a copy thereof to the Agent, and the
Agent shall promptly notify the other Banks of the receipt by it of any such
notice.
 
     Section 11.13. Severability.  The provisions of this Agreement are intended
to be severable. If any provision of this Agreement shall be held invalid or
unenforceable in whole or in part in any jurisdiction such provision shall, as
to such jurisdiction, be ineffective to the extent of such invalidity or
unenforceability without in any manner affecting the validity or enforceability
thereof in any other jurisdiction or the remaining provisions hereof in any
jurisdiction.

                             CONTINGENT LIABILITIES
 
     A. Operating lease between LMV Leasing, Inc. and Philadelphia Suburban
Water Company for automobiles and other equipment through 1997. During the next
four years, $1,191,000 of future minimum lease payments are due: $768,000 in
1994, $314,000 in 1995, $108,000 in 1996, and $1,000 in 1997.
 
     B. Suretyship agreements in the amount of $4,137,461.00 as of March 17,
1994. The major portion of this amount, $3,352,961, arises from the bonding
requirements under the Pennsylvania Residual Waste Regulations relating to the
future closure of landfills used to dispose of water treatment plant sludge. The
balance of the surety bonds support various licenses, permits and condemnations.
 
     C. Agreements for the purchase of water are maintained with Chester Water
Authority and Bucks County Water and Sewer Authority. The agreements stipulate
purchases of minimum quantities of water to the year 2017. As of December 31,
1993, the estimated annual commitments related to such purchases total
approximately $2,637,000 through 1998.
 
     D. In the normal course of business, after PSWC performs excavation work in
various highways in order to access water mains and other underground
facilities, PSWC is required by township and state permits to restore the
excavated area.

                             ENVIRONMENTAL MATTERS
 
     A. In its water treatment process, PSWC uses chemicals, including chlorine,
caustic soda and sodium chlorite, which are listed as hazardous substances.
These chemicals are, in all material respects, stored and used at PSWC's plants
and facilities in accordance with the Environmental Laws.
 
     B. PSWC operates a central laboratory at its Bryn Mawr facility for
analysis of drinking water samples. To perform required analyses, PSWC maintains
small quantities of solvents, reagents and chemical standards, some of which are
listed as hazardous substances. These materials, in all material respects, are
stored and used in compliance with the Environmental Laws.
 
     C. By letter dated March 4, 1992, the New Jersey Department of
Environmental Protection and Energy ('DEPE') advised PSWC and over 70 other
entities of a pending arbitration proceeding involving a company named 'Frigid,
Inc.' and the New Jersey Spill Compensation Fund (the 'Spill Fund'). The
arbitration involves Frigid's claim to recover damages totaling $2,500,000
allegedly resulting from a fire on April 11, 1983 in a warehouse near Frigid's 
facility. During the fire, hazardous substances were allegedly discharged from 
the burning warehouse. DEPE has informed PSWC that it believes that some 
materials from PSWC may have been transported to and stored at the warehouse 
where the fire occurred. DEPE has identified PSWC and the other 70 entities as 
potentially responsible parties. Under New Jersey law, a party who is in any 
way responsible for a hazardous substance discharge may be strictly liable and 
jointly and severally liable for the cost of clean-up. The arbitration will not 
address PSWC's liability, but only whether Frigid can recover from the Spill 
Fund. The arbitration is scheduled for March, 1994 and the DEPE and certain of 
the potentially responsible parties are expected to contest the amount and 
validity of Frigid's claim. If Frigid is successful in its claim, the DEPE 
would likely seek to recover from the potentially responsible parties the 
amount paid from the Spill Fund. Frigid, Inc./Enertron Industries, Inc. 
Arbitration.
 
     D. During the week of March 6, 1994, PSWC was advised by an outside party
that the State of New Jersey had instituted a separate action in the Superior
Court of Essex County seeking reimbursement of the costs incurred by the State
as a result of warehouse fire mentioned in the Frigid summary above. PSWC was
advised, but has not been able to confirm, that the State of New Jersey is
seeking reimbursement for approximately $3.5 million dollars. PSWC believes that
it has been named as a defendant along with approximately 100 other entities. As
of March 15, 1994, PSWC had not been served with this Complaint. State of New
Jersey, Department of Environmental Protection and Energy v. Signo Trading
International.

Corporation.

                       PHILADELPHIA SUBURBAN CORPORATION
                      1994 INCENTIVE COMPENSATION PROGRAM
 
BACKGROUND
 
o During the first quarter of 1989, the Company and its compensation consultant
  conducted a feasibility study to determine whether the Company should
  implement an incentive compensation plan. The study was prompted by the
  positive experience of other investor-owned water companies and PSC's
  experience with incentive compensation.
 
o The study included interviews with PSWC and PSC executives and an analysis of
  competitive compensation levels. Based on the results, the compensation
  consultant recommended that the Company's objectives and competitive practice
  supported the adoption of an annual incentive plan.
 
o The program has two components -- a Management Incentive Plan and an Employee
  Recognition Plan.
 
o After three years of experience with the Incentive Compensation Program,
  management has recommended certain changes to the Program to ensure the
  Program provides the appropriate incentive to the officers and managers of the
  Company. The 1994 Management Incentive Plan will cover all officers and
  managers of Philadelphia Suburban Corporation, and its subsidiaries, except
  Utility & Municipal Services, Inc., which is covered by a separate incentive
  bonus arrangement based on the profitability of that subsidiary.
 
MANAGEMENT INCENTIVE PLAN
 
o Performance Measures
 
  -- PSC's actual after-tax net income from continuing operations relative to
     the annual budget will be the primary measure. Each year a 'Target Net
     Income' level will be established. For purposes of the Plan, the Target Net
     Income may differ from the budgeted net income level. For 1994, the Target
     Net Income will exclude the impact of FAS 106, the effect of any unbudgeted
     extraordinary gains or losses, changes in accounting principles, changes in
     tax rates and any gains or losses related to the discontinued operations.
 
  -- Based on a review of historic performance, the minimum or threshold level
     of performance is set at 90 percent of the Target Net Income. That is, no
     bonus awards will be made if actual net income is less than 90 percent of
     the Target Net Income for the year. No additional bonus will be earned for
     results exceeding 120 percent of the Target Net Income.
 
  -- Each individual's performance and achievement of his or her objectives will
     also be evaluated and factored into the bonus calculation.
 
o Participation
 
  -- Participation in the Plan will be determined each year. Each participant
     will be assigned a 'Target Bonus Percentage' ranging from 5 to 40 percent
     of salary depending on duties and responsibilities.
 
  -- Actual bonuses may range from 0, if the Company's financial results fall
     below threshold or the participant's performance rating is Below
     Expectations, to 225 percent if performance -- both company and individual
     -- is rated at 150 percent.
 
  -- Exhibit 1 shows the recommended participants and the Target Bonus
     Percentages for the current year.

o Example 2
 
  -- Using the same salary and target bonus, but assuming Company performance
     was less than 90 percent of Target Net Income, there would be no bonus
     earned.
 
     Calculation:
 
                     $7,000  x  0  x  90%  =  0
 
o Example 3
 
  -- Similarly, if individual Performance is rated Below Expectations, no bonus
     would be earned regardless of the Company Rating.
 
     Calculation:
 
                    $7,000  x  100%  x  0  =  0

                       PHILADELPHIA SUBURBAN CORPORATION
                         1994 EQUITY COMPENSATION PLAN
 
1. PURPOSE
 
     The purpose of this plan (the 'Plan') is to provide an incentive, in the
form of a proprietary interest in Philadelphia Suburban Corporation (the
'Corporation'), to officers and other key employees of the Corporation and its
subsidiaries and key consultants who are in a position to contribute materially
to the successful operation of the business of the Corporation, to increase
their interest in the Corporation's welfare, and to provide a means through
which the Corporation can attract and retain officers and other key employees
and key consultants of significant abilities.
 
2. ADMINISTRATION
 
     This Plan shall be administered by a Committee (the 'Committee') of the
Board of Directors of the Corporation. The Committee shall consist of three or
more of those members of the Board of Directors who are not eligible, and for at
least one year prior to their appointment were not eligible, to receive grants
under the Plan or any other plan of the Corporation or any of its affiliates
entitling the participants therein to acquire stock, stock options, stock
appreciation rights or dividend equivalents of the Corporation or any of its
affiliates.
 
     From time to time the Committee or the Board of Directors may make grants,
subject to the terms of the Plan, with respect to such number of shares of
Common Stock of the Corporation as the Committee or the Board of Directors, each
acting in its sole discretion, may determine. All references to the Committee
hereunder shall also mean the Board of Directors when acting pursuant to its
authority to make grants under the Plan.
 
     Subject to the provisions of the Plan, the Committee shall be authorized to
interpret the Plan and the grants made under the Plan, to establish, amend and
rescind any rules and regulations relating to the Plan, to determine the terms
and provisions of the agreement related to grants described in Section 9 hereof,
and to make all other determinations, including factual determinations,
necessary or advisable for the administration of the Plan. The Committee may
correct any defect, supply any omission and reconcile any inconsistency in the
Plan or in any option or grant in the manner and to the extent it shall be
deemed desirable to carry it into effect. The determinations of the Committee in
the administration of the Plan, as described herein, shall be final and
conclusive. The Committee may adopt such rules and regulations as it deems
necessary for governing its affairs.
 
3. GRANTS
 
     Pursuant to the terms of the Plan, the Committee shall have the authority
to grant stock options to officers and other key employees and key consultants
and restricted stock and dividend equivalents to officers and other key
employees (hereinafter collectively referred to as the 'Grants'). All Grants
shall be subject to the terms and conditions set forth herein and to those other
terms and conditions consistent with this Plan as the Committee deems
appropriate and as are specified in writing by the Committee in the agreement
described in Section 9 of the Plan (the 'Agreement'). Grants under a particular
Section of the Plan need not be uniform as among the employees or consultants
and Grants under two or more Sections of the Plan may be combined in one
instrument.
 
4. SHARES SUBJECT TO THE PLAN
 
     Subject to adjustment as provided in Section 15, the maximum aggregate
number of shares of the Common Stock of the Corporation that may be issued or
transferred under the Plan shall be 450,000 shares. The maximum number of shares
of Common Stock that may be issued or transferred under the Plan subject to
restricted stock grants is 25,000 shares of Common Stock. Shares deliverable
under the 
 
                                       1
<PAGE>

Plan may be authorized and unissued shares or treasury shares, as the
Committee may from time to time determine. Shares of Common Stock related to the
unexercised or undistributed portion of any terminated, expired or forfeited
Grant for which no material benefit was received by a grantee also may be made
available for distribution in connection with future Grants under the Plan.
 
5. ELIGIBILITY
 
     Only officers, key employees and key consultants of the Corporation and its
subsidiaries (excluding any director who is not a salaried employee) shall be
eligible for Grants under the Plan. The term 'subsidiaries' shall mean any
corporation in an unbroken chain of corporations beginning with the Corporation,
if at the time of the Grant, each of the corporations other than the last
corporation in the unbroken chain owns stock possessing 50% or more of the total
combined voting power of all classes of stock in one of the other corporations
in such chain.
 
6. GRANTING OF OPTIONS
 
     The Committee may, from time to time, grant stock options to eligible
officers and other key employees and shall designate options at the time of
grant as either 'incentive stock options' intended to qualify as such under
section 422 of the Internal Revenue Code of 1986, as from time to time amended
or any successor statute of similar purpose (the 'Code'), or 'nonqualified stock
options', which options are not intended to so qualify. The Committee may, from
time to time, grant nonqualified stock options to key consultants. Except as
hereinafter provided, options granted pursuant to the Plan shall be subject to
the following terms and conditions:
 
     (a) Price
 
     The purchase price per share of stock deliverable upon the exercise of each
option shall be not less than 100% of the fair market value of the Corporation's
Common Stock on the date the option is granted. The fair market value shall be
the mean of the high and low sale prices of the Corporation's Common Stock on
the New York Stock Exchange composite tape or other recognized market source, as
determined by the Committee, on the date the option is granted, or if there is
no sale on such date, then the mean of such high and low sale prices on the last
previous day on which a sale is reported. In any event, in case of the grant of
an incentive stock option, the fair market value shall be determined in a manner
consistent with section 422 of the Code.
 
     Shares may be purchased only by delivering a notice of exercise to the
Committee with accompanying payment of the purchase price therefor in full. Such
notice may instruct the Corporation to deliver shares of Common Stock due upon
the exercise of the option to any registered broker or dealer in lieu of
delivery to the grantee. Such instructions must designate the account into which
the shares are to be deposited. The grantee may tender this notice of exercise,
which has been properly executed by the grantee, and the aforementioned delivery
instructions to any broker or dealer. With the consent of the Committee, payment
of the purchase price may be made, in whole or in part, through the surrender of
shares of the Common Stock of the Corporation (including without limitation
shares of Common Stock acquired pursuant to the option then being exercised) at
the fair market value of such shares determined as of the last trading day prior
to the date on which the option is exercised, in the same manner set forth in 
the above paragraph.
 
        (b) Terms of Options
 
     The term during which each incentive stock option may be exercised shall be
determined by the Committee, but in no event shall an incentive stock option be
exercisable in whole or in part more than 10 years from the date it is granted
and in no event shall a nonqualified stock option be exercisable in whole or in
part more than 10 years and one day from the date it is granted. All rights to
purchase pursuant to an option shall, unless sooner terminated, expire at the
date designated by the Committee.
 
     The Committee shall determine the date on which each option shall become
exercisable and may provide that an option shall become exercisable in
installments. The shares comprising each installment may be purchased in whole
or in part at any time after such installment becomes
 
                                       2
<PAGE>

exercisable. The Committee may, in its sole discretion, accelerate the time at 
which any option may be exercised in whole or in part. Notwithstanding any 
determinations by the Committee regarding the exercise period of any option, 
all outstanding options shall become immediately exercisable upon a Change of 
Control of the Corporation (as defined herein).
 
     (c) Termination of Employment
 
     Upon the termination of a grantee's employment for any reason (except as a
result of retirement, disability or death), the options held by such grantee
shall terminate. Notwithstanding the fact that, in all cases, a grantee's
employment shall be deemed to have terminated upon the sale of a subsidiary of
the Corporation that employs such grantee, the Committee, in its sole
discretion, may extend the period during which any option held by such a grantee
may be exercised after such sale to the earliest of (i) a date which is not more
than three years from the date of the sale of the subsidiary, (ii) the date of
the grantee's termination of employment with the subsidiary (or successor
employer) following such sale for reasons other than retirement, disability or
death, (iii) the date which is one year from the date of the grantee's
termination of employment with the subsidiary on account of the grantee's total
disability (as defined in section 22(e)(3) of the Code), or three months from
the date of such termination if on account of retirement or a disability other
than a total disability, or (iv) the expiration of the original term of the
option as established at the time of grant. The Committee, in its sole
discretion, may similarly extend the period of exercise of any option held by a
grantee employed by the Corporation whose employment with the Corporation is
terminated in connection with the sale of a subsidiary of the Corporation.
 
     Upon termination of a grantee's employment as a result of retirement,
disability or death, the period during which the options may be exercised shall
not exceed: (i) one year from the date of such termination of employment in the
case of death and (ii) two years from the date of such termination in the case
of permanent and total disability (within the meaning of section 22(e)(3) of the
Code) or retirement; and (iii) three months from the date of such termination of
employment in the case of other disability; provided, however, that in no event
shall the period extend beyond the expiration of the option term.
 
     Subject to the foregoing, in the event of death, such options may be
exercised by a grantee's legal representative or beneficiary, but only to the
extent that installments had accrued as of the date of death. Notwithstanding
the foregoing, the Committee, in its sole discretion, may determine that
installments that have not accrued as of the date of the grantee's death,
termination of employment on account of permanent and total disability (within
the meaning of section 22(e)(3) of the Code) or other termination of employment
may also be exercised by a grantee, or in the case of death, a grantee's legal
representative or beneficiary. Transfer from the Corporation to a subsidiary,
from a subsidiary to the Corporation, or from one subsidiary to another, shall
not be deemed to be a termination of employment. All references in this Section
6(c) to the termination of a grantee's employment shall include the termination
of a consultant's relationship with the Corporation or any subsidiary.
 
     (d) Limits on Incentive Stock Options.

     Each Grant of an incentive stock option shall provide that it (i) is not
transferable by the grantee otherwise than by will or the laws of descent and
distribution or, if permitted under Rule 16b-3 of the Securities Exchange Act of
1934 (the 'Exchange Act') and if permitted in any specific case by the Committee
in its sole discretion, pursuant to a qualified domestic relations order as
defined under the Code or Title I of the Employee Retirement Income Security Act
of 1974, as amended ('ERISA') or the rules thereunder, and (ii) is exercisable,
during the grantee's lifetime, only by the grantee and that the aggregate fair
market value of the Common Stock on the date of the Grant with respect to which
incentive stock options are exercisable for the first time by a grantee during
any calendar year under the Plan and under any other stock option plan of the
Corporation shall not exceed the limitation set forth in section 422(d) of the
Code. An incentive stock option shall not be granted to any grantee who, at the
time of grant, owns stock possessing more than 10 percent of the total combined
voting power of all classes of stock of the Corporation or subsidiary of the
Corporation, unless the exercise price of the incentive stock option is no less
than 110% of the fair market value per share on the date of grant and 

 
                                      3
<PAGE>

the term of the incentive stock option is not more than five years. Unless a 
grantee could otherwise transfer Common Stock issued pursuant to an incentive 
stock option granted hereunder without incurring liability under section 16(b) 
of the Exchange Act, at least six months must elapse from the date of 
acquisition of an incentive stock option to the date of disposition of the 
Common Stock issued upon exercise of such option.
 
7. RESTRICTED STOCK GRANTS
 
     The Committee may issue or transfer shares of Common Stock of the
Corporation to an eligible officer or other key employee subject to the maximum
number of shares of Common Stock reserved for issuance in connection with
restricted stock grants described in Section 4 of the Plan. The following
provisions are applicable to restricted stock grants:
 
          (a) General Requirements. Shares of Common Stock of the Corporation
     issued pursuant to restricted stock grants may be issued for consideration
     or for no consideration. Subject to any other restrictions by the Committee
     as provided pursuant to Section 7(e), restrictions on the transfer of
     shares of Common Stock set forth in Section 7(c) shall lapse on such date
     or dates as the Committee may approve until the restrictions have lapsed on
     100% of the shares; provided, however, that upon a Change of Control of the
     Corporation, all restrictions on the transfer of the shares which have not,
     prior to such date, been forfeited shall immediately lapse. The period of
     years during which the restricted stock grant will remain subject to
     restrictions will be designated in the Agreement (the 'Restriction
     Period'). Prior to the lapse of the Restriction Period the shares of Common
     Stock granted to any grantee shall be held by the Corporation.
 
          (b) Number of Shares. The Committee shall grant to each grantee a
     number of shares of Common Stock of the Corporation determined in its sole
     discretion.
 
          (c) Requirement of Employment. If the grantee's employment terminates
     during the Restriction Period, the restricted stock grant terminates as to
     all shares covered by the Grant as to which restrictions on transfer have
     not lapsed, and those shares of Common Stock must be immediately returned
     to the Corporation. The Committee may, however, provide for complete or
     partial exceptions to this requirement as it deems equitable.
 
          (d) Restrictions on Transfer and Legend on Stock Certificate. During
     the Restriction Period, a grantee may not sell, assign, transfer, pledge,
     or otherwise dispose of the shares of Common Stock to which such
     Restriction Period applies except to a Successor Grantee (as defined in
     Section 10 of the Plan). Each certificate for a share issued or transferred
     under a restricted stock grant shall contain a legend giving appropriate
     notice of the restrictions in the Grant. The grantee shall be entitled to
     have the legend removed from the stock certificate or certificates covering
     any of the shares subject to restrictions when all restrictions on such
     shares have lapsed.
 
          (e) Lapse of Restrictions. All restrictions imposed under the
     restricted stock grant shall lapse upon the expiration of the applicable
     Restriction Period; provided, however, that upon a Change of Control of the
     Corporation, all restrictions on the transfer of shares which have not,
     prior to such date, been forfeited shall immediately lapse. In addition, 
     the Committee may determine as to any or all restricted stock grants, that
     all the restrictions shall lapse, without regard to any Restriction Period,
     under such circumstances as it deems equitable.
 
8. DIVIDEND EQUIVALENTS
 
     The Committee may grant dividend equivalents to eligible officers and other
key employees either alone or in conjunction with all or part of any option
granted under the Plan. A dividend equivalent shall be equal to the dividend
payable on a share of Common Stock of the Corporation. The amount of dividend
equivalents for any grantee (the 'Dividend Equivalent Amount') is determined by
multiplying the number of dividend equivalents subject to the Grant by the
per-share cash dividend, or the per-share fair market value (as determined by
the Committee) of any dividend in other than cash, 

 
                                       4
<PAGE>

paid by the Corporation on each record date for the payment of a dividend 
during the period described in Section 8(a).
 
     (a) Amount of Dividend Equivalent Credited.
 
     The Corporation shall credit to an account for each grantee maintained by
the Corporation in its books and records on each record date, from the date of
grant until the earlier of the date of (i) the end of the applicable
accumulation period designated by the Committee at the time of grant, (ii) the
date of the termination of employment for any reason (including retirement),
other than total disability (as defined in section 22(e)(3) of the Code) or
death of the grantee, or as otherwise determined by the Committee, in its sole
discretion, at the time of a grantee's termination of employment or (iii) the
end of a period of four years from the date of grant, that portion of the
Dividend Equivalent Amount for each such grantee attributable to each record
date. The Corporation shall maintain in its books and records separate accounts
which identify each Grantee's Dividend Equivalent Amount. Except as set forth in
Section 8(e) below, no interest shall be credited to any such account.
 
     (b) Payment of Credited Dividend Equivalents.
 
     The Committee, at the time of grant, shall designate the percentage of each
grantee's Dividend Equivalent Amount that shall be paid to the grantee at the
end of an applicable performance period (the 'Performance Period') of four years
from the date of grant (the Committee, in its sole discretion, shall retain the
right to designate a longer or shorter Performance Period at the time of grant);
provided, however, that such Performance Period shall be:
 
          (i) reduced by one year for each calendar year during the applicable
     Performance Period ending after the date of grant in which the measurable
     performance criteria established by the Committee at the time of grant for
     the applicable Performance Period exceeds the targets for such criteria
     established by the Committee at the time of grant.
 
          (ii) increased by one year for each calendar year during the
     applicable Performance Period ending after the date of grant in which the
     measurable performance criteria established by the Committee at the time of
     grant for the applicable Performance Period is less than the targets for
     such criteria established by the Committee at the time of grant.
 
          (iii) In no event shall the Performance Period be reduced to less than
     two years or increased to more than eight years from the date of grant.
 
          (iv) In the event that the Performance Period is shorter than the
     period described in Section 8(a), a grantee shall receive the payment of
     the amount credited to his account at the end of the applicable Performance
     Period and any portion of the Dividend Equivalent Amount not yet so
     credited to his account shall be paid on the Corporation's normal dividend
     payment dates until the grantee's Dividend Equivalent Amount for the period
     described in Section 8(a) is fully paid to the grantee.
 
     (c) Timing of Payment of Dividend Equivalents.

     Except as otherwise determined by the Committee in the event of a grantee's
termination from employment prior to the end of the applicable Performance
Period, no payments of the Dividend Equivalent Amount shall be made until the
end of the applicable Performance Period and no payments shall be made to any
grantee whose employment by the Corporation or a subsidiary terminates prior to
the end of the applicable Performance Period for any reason other than
retirement under the Corporation's or a subsidiary's retirement plan, death or
total disability (as defined in section 22(e)(3) of the Code). Subject to
Section 8(b)(iv), as soon as practicable after the end of such Performance
Period, unless a grantee shall have made an election under Section 8(f) to defer
receipt of any portion of such amount, a grantee shall receive 100% of the
Dividend Equivalent Amount payable to him. Notwithstanding the foregoing, upon a
Change of Control of the Corporation, any Dividend Equivalent Amount or portion
thereof, which has not, prior to such date, been paid to the grantee or
forfeited shall immediately become payable to the grantee without regard to
whether the applicable Performance Period has ended.
 
                                       5
<PAGE>
 
     (d) Form of Payment. The Committee shall have the sole discretion to
determine whether the Corporation's obligation in respect of the payment of a
Dividend Equivalent Amount shall be paid solely in credits to be applied toward
payment of the option price under then exercisable options, solely in cash or
partly in such credits and partly in cash.
 
     (e) Interest on Dividend Equivalents. From a date which is 45 days after
the end of the applicable Performance Period until the date that the Dividend
Equivalent Amount payable to the grantee is paid to such grantee, the account
maintained by the Corporation in its books and records with respect to such
dividend equivalents shall be credited with interest at a market rate determined
by the Committee.
 
     (f) Deferral of Dividend Equivalents. A grantee shall have the right to
defer receipt of any Dividend Equivalent Amount payments if he shall elect to do
so on or prior to December 31 of the year preceding the beginning of the last
full year of the applicable Performance Period (or such other time as the
Committee shall determine is appropriate to make such deferral effective under
the applicable requirements of federal tax laws). The terms and conditions of
any such deferral (including the period of time thereof and any earnings on the
deferral) shall be subject to approval by the Committee and all deferrals shall
be made on a form provided a grantee for this purpose.
 
9. AGREEMENT WITH GRANTEES
 
     Each grantee who receives a Grant under the Plan shall enter into an
agreement with the Corporation which shall contain such provisions, consistent
with the provisions of the Plan, as may be established from time to time by the
Committee.
 
10. TRANSFERABILITY OF GRANTS
 
     Only a grantee or his or her authorized legal representative may exercise
rights under a Grant. Such persons may not transfer those rights except by will
or by the laws of descent and distribution or, if permitted under Rule 16b-3 of
the Exchange Act and if permitted in any specific case by the Committee in their
sole discretion, pursuant to a qualified domestic relations order as defined
under the Code or Title I of ERISA or the rules thereunder. When a grantee dies,
the personal representative or other person entitled to succeed to the rights of
the grantee ('Successor Grantee') may exercise such rights. A Successor Grantee
must furnish proof satisfactory to the Corporation of his or her right to
receive the Grant under the grantee's will or under the applicable laws of
descent and distribution.
 
11. FUNDING OF THE PLAN
 
     This Plan shall be unfunded. The Corporation shall not be required to
establish any special or separate fund or to make any other segregation of
assets to assure the payment of any Grants under this Plan. Subject to Section
8(e), in no event shall interest be paid or accrued on any Grant, including
unpaid installments of Grants.

12. RIGHTS OF GRANTEES
 
     Nothing in this Plan shall entitle any grantee or other person to any claim
or right to receive a Grant under this Plan. Neither this Plan nor any action
taken hereunder shall be construed as giving any grantee any rights to be
retained in the employ of the Corporation or to be retained as a consultant by
the Corporation.
 
13. WITHHOLDING OF TAXES
 
     The Corporation shall have the right to deduct from all Grants paid in cash
any federal, state or local taxes required by law to be withheld with respect to
such cash awards. The grantee or other person receiving such shares shall be
required to pay to the Corporation the amount of any such taxes which the
Corporation is required to withhold with respect to such Grants. With respect to
Grants of restricted stock or nonqualified stock options, the Corporation shall
have the right to require that the grantee make such provision, or furnish the
Corporation such authorization as may be necessary or 
 
                                       6
<PAGE>

desirable so that the Corporation may satisfy its obligation, under applicable 
income tax laws, to withhold for income or other taxes due upon or incident to 
such restricted stock or the exercise of such nonqualified stock options.
 
     The Committee may adopt such rules, forms and procedures as it considers
necessary or desirable to implement such withholding procedures, which rules,
forms and procedures shall be binding upon all grantees, and which shall be
applied uniformly to all grantees similarly situated.
 
14. LISTING AND REGISTRATION
 
     Each Grant shall be subject to the requirement that, if at any time the
Committee shall determine in its discretion that the listing, registration or
qualification of the Grant or the shares subject to the Grant upon any
securities exchange or under any state or federal law, or the consent or
approval of any governmental regulatory body, is necessary or desirable as a
condition of, or in connection with, such Grant or the issue or purchase of
shares thereunder, no such Grant may be exercised in whole or in part unless
such listing, registration, qualification, consent or approval shall have been
effected or obtained free of any conditions not acceptable to the Committee.
 
15. ADJUSTMENT OF AND CHANGES IN COMMON STOCK OF THE CORPORATION.
 
     In the event of a reorganization, recapitalization, change of shares, stock
split, spin-off, stock dividend, reclassification, subdivision or combination of
shares, merger, consolidation, rights offering, or any other change in the
corporate structure or shares of the Corporation, the Committee shall make such
adjustment as it deems appropriate in the number and kind of shares authorized
by the Plan, in the number and kind of shares covered by Grants made under the
Plan, in the purchase prices of outstanding options or the terms and conditions
applicable to dividend equivalents.
 
16. RIGHTS OF GRANTEES
 
     Neither the grantee nor any personal representative shall be, or have any
of the rights and privileges of, a shareholder of the Corporation in respect of
any shares related to any Grant or purchasable upon the exercise of any option,
in whole or in part, unless and until certificates for such shares have been
issued. Notwithstanding the foregoing, a grantee who receives a grant of
restricted stock shall have all rights of a shareholder, except as set forth in
Section 7(d), during the Restriction Period, including the right to vote and
receive dividends.
 
17. CHANGE OF CONTROL OF THE CORPORATION
 
     As used herein, a 'Change of Control' shall be deemed to have taken place
if (i) any Person (including any individual, firm, corporation, partnership or
other entity except the Corporation or any employee benefit plan of the
Corporation or of any Affiliate or Associate, both as defined in Rule 12b-2 of
the General Rules and Regulations under the Securities Exchange Act of 1934, as
amended, any Person or entity organized, appointed or established by the 
Corporation for or pursuant to the terms of any such employee benefit plan), 
together with all Affiliates and Associates of such Person, shall become the 
beneficial owner in the aggregate of 20% or more of the Common Stock of the 
Corporation then outstanding or (ii) during any twenty-four month period, 
individuals who at the beginning of such period constituted the Board of 
Directors cease for any reason to constitute a majority thereof, unless the 
election, or the nomination for election by the Corporation's shareholders, 
of at least seventy-five percent of the directors who were not directors at 
the beginning of such period was approved by a vote of at least seventy-five 
percent of the directors in office at the time of such election or nomination 
who were directors at the beginning of such period. Notwithstanding the 
foregoing, a Change in Control shall not be deemed to have taken place under 
clause (i) of the immediately preceding sentence if (a) such Person becomes 
the beneficial owner in the aggregate of 20% or more of the Common Stock of 
the Corporation then outstanding as a result of an inadvertent acquisition by 
such Person if such Person, as soon as practicable, divests itself of a 
sufficient amount of its Common Stock so that it no longer owns 20% or more 
of the Common Stock then outstanding, as determined by the Board of 
 
                                       7
<PAGE>

Directors  of the Corporation, or (ii) the shares of Common Stock required to 
be counted  in order to meet the 20% minimum threshold described under such 
clause  (i) include any of the shares described in subsections (i) through (vi) 
of section 2543(b) of the Pennsylvania Business Corporation Law of 1988 
(15 Pa.C.S.A. section 2543(b)) as in effect on the date of adoption of the Plan.
 
18. AMENDMENT AND TERMINATION
 
     (a) The Plan may be amended by the Board of Directors of the Corporation as
it shall deem advisable to ensure such qualification and conform to any change
in the law or regulations applicable thereto, including such new regulations as
may be enacted pertaining to the tax treatment of incentive stock options to be
granted under this Plan, or in any other respect that the Board may deem to be
in the best interest of the Corporation; provided, however, that the Board may
not, without the authorization and approval of the shareholders of this
Corporation (i) materially increase the benefits accruing to participants under
the Plan, (ii) increase the number of shares which may be issued under the Plan,
except pursuant to Section 15 hereof, or (iii) materially modify the
requirements as to eligibility for participation in the Plan.
 
     The Board of Directors shall not amend the Plan if the amendment would
cause the Plan or any Grant, or the exercise of any right under the Plan to fail
to comply with the requirements of Rule 16b-3 under the Securities Exchange Act
of 1934, as amended, or if such amendment would cause the Plan or the Grant or
exercise of an incentive stock option under the Plan to fail to comply with the
requirements of section 422 of the Code including, without limitation, a
reduction of the option price set forth in Section 6(a) or an extension of the
period during which an incentive stock option may be exercised as set forth in
Section 6(b).
 
     (b) The Board of Directors of the Corporation may, in its discretion,
terminate, or fix a date for the termination of, the Plan. Unless previously
terminated, the Plan shall terminate on May 19, 2004 and no Grants shall be made
under the Plan after such date.
 
     (c) A termination or amendment of the Plan that occurs after a Grant is
made shall not result in the termination or amendment of the Grant unless the
grantee consents or unless the Committee acts under Section 19. The termination
of the Plan shall not impair the power and authority of the Committee with
respect to an outstanding Grant. Whether or not the Plan has terminated, an
outstanding Grant may be terminated or amended under this Section 18 or may be
amended by agreement of the Corporation and the grantee consistent with the
Plan.
 
19. COMPLIANCE WITH LAW.
 
     The Plan, the exercise of Grants and the obligations of the Corporation to
issue or transfer shares of Common Stock under Grants shall be subject to all
applicable laws, including any applicable federal or Pennsylvania state law, and
to approvals by a governmental or regulatory agency as may be required. With
respect to persons subject to section 16 of the Exchange Act, it is the intent
of the Corporation that the Plan and all transactions under the Plan comply 
with all applicable conditions of Rule 16b-3 or its successors under the 
Exchange Act. The Committee may revoke any Grant if it is contrary to law or 
modify a Grant to bring it into compliance with any valid and mandatory 
government regulation. The Committee may also adopt rules regarding the 
withholding of taxes on payments to grantees. The Committee may, in its sole 
discretion, agree to limit its authority under this Section.
 
20. EFFECTIVE DATE OF THE PLAN
 
     The Plan shall be effective as of April 1, 1994, subject to the approval by
a majority of the Corporation's shareholders within twelve months of such
effective date. No Grant shall be made pursuant to the Plan on or after the
tenth anniversary of the date of shareholder approval, but Grants made prior to
such tenth anniversary may extend beyond that date.

               PHILADELPHIA SUBURBAN CORPORATION AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              (IN THOUSANDS OF DOLLARS, EXCEPT PER SHARE AMOUNTS)
 
Summary of Significant Accounting Policies
 
Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its subsidiaries, all of which are wholly-owned. The business of
Philadelphia Suburban Corporation ('PSC' or the 'Company') is conducted almost
entirely through its subsidiary, Philadelphia Suburban Water Company, a
regulated public utility. All material intercompany accounts and transactions
have been eliminated.
 
Recognition of Revenues
 
     Utility revenues include amounts billed to customers on a cycle basis and
unbilled amounts based on estimated usage from the latest billing to the end of
the accounting period.
 
     Nonutility revenues include amounts billed to customers and amounts
accruable under contract terms.
 
Property, Plant and Equipment and Depreciation
 
     Property, plant and equipment consist primarily of utility plant. The cost
of additions includes contracted cost, direct labor and fringe benefits,
materials, allowable overheads and, for certain utility plant, allowance for
funds used during construction. Utility expenditures for maintenance and
repairs, including minor renewals and betterments, are charged to operating
expenses in accordance with the Uniform System of Accounts prescribed by the
Pennsylvania Public Utility Commission ('PUC'). The cost of new units of
property and betterments are capitalized. When units of utility property are
replaced, retired or abandoned, the recorded value thereof is credited to the
asset account and such value, together with the net cost of removal, is charged
to accumulated depreciation.
 
     The straight-line remaining life method is used to compute depreciation on
utility plant. The straight-line method is used with respect to transportation
and mechanical equipment and nonutility plant and equipment.
 
Allowance for Funds Used During Construction
 
     The allowance for funds used during construction ('AFUDC') represents the
estimated cost of funds used to finance the construction of utility plant. AFUDC
is applied to construction projects requiring more than one month to complete.
No AFUDC is applied to projects funded by customer advances for construction or
contributions in aid of construction. AFUDC includes the net cost of borrowed
funds and a rate of return on other funds when used, and is recovered through
water rates as the utility plant is depreciated. The amount of AFUDC related to
equity funds was $338, $147 and $730 in 1993, 1992 and 1991, respectively.
 
Deferred Charges
 
     Deferred bond and preferred stock issuance expenses are amortized by the
straight-line method over the life of the related issues.
 
     Call premiums related to the early redemption of long-term debt of the
utility, along with the unamortized balance of the related issuance expense, are
deferred and amortized over the life of the long-term debt used to fund the
redemption.
 
     The cost of purchased software that is used within the Company is amortized
using the straight-line method over five years.
 
                                       4
<PAGE>

     Expenses associated with filing for rate increases are deferred and
amortized over the estimated period the rates will be in effect, approximately
one year.
 
Income Taxes
 
     Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, 'Accounting for Income Taxes' ('SFAS 109'). SFAS
109 requires a change from the deferred method of accounting for income taxes of
Accounting Principles Board Opinion ('APB') 11 to the asset and liability method
of accounting for income taxes. The asset and liability method requires the
recognition of deferred tax liabilities and assets for the expected future tax
consequences attributable to differences between financial statement carrying
amounts of existing assets and liabilities and their tax carrying values.
 
     Deferred taxes were not previously provided under APB 11 for those
temporary differences for which the tax effects were flowed through to the
ratepayer. The cumulative effect of the change in accounting for income taxes
resulted in a significant increase in deferred tax liabilities for the water
utility. However it did not have a material effect on net income since the
increase in deferred taxes was offset by increases to a regulatory asset and
utility plant.
 
Customers' Advances for Construction
 
     Advances are received from customers, real estate developers and builders
principally for construction of water main extensions and are refundable as
operating revenues are earned or as new customers are connected after the
completion of construction. After all refunds are made, any remaining balance is
transferred to contributions in aid of construction.
 
Contributions in Aid of Construction
 
     Contributions in aid of construction include direct contributions and the
portion of customers' advances for construction which become nonrefundable.
 
Inventories, Materials and Supplies
 
     Inventories are stated at average cost, not in excess of market value.
 
Acquisitions
 
     In December 1993, the water utility acquired the franchise rights and the
water utility assets of the Borough of Malvern for $1,323 in cash. This water
supply system serves approximately 859 metered customers in a one square mile
area surrounded by the water utility's existing service territory. Assets
acquired consist primarily of utility plant in service and have been classified
in the accompanying consolidated financial statements on a net basis as
property, plant and equipment pending final allocation. Revenues in 1993 of the
acquired water supply system amounted to approximately $250.
 
     In November 1993, the water utility submitted a proposal to purchase the
water utility assets of a municipally-owned water system for a purchase price in
excess of $20,000. The municipality is presently evaluating the water utility's
proposal, versus one other that it has received, and expects to select the
successful bidder sometime in 1994. The municipal water system serves
approximately 13,000 customers over a 23-square-mile service area contiguous to
the water utility's service territory. Annual revenues from this system
approximate $4,500.
 
     In December 1992, the water utility acquired the franchise rights and the
water utility assets of the West Whiteland Township and the Uwchlan Township
Municipal Authority water systems for $9,128
 
 
                                       5
<PAGE>

in cash and issuance of a $1,777 9% installment note. These water supply 
systems serve approximately 6,900 metered customers in a 40-square-mile area
contiguous to the water utility's service territory. Assets acquired consist
primarily of utility plant in service. Revenues included in the consolidated
financial statements related to the acquired water supply systems amounted to 
approximately $2,052 in 1993.

Discontinued Operations
 
     The Board of Directors authorized the sale of substantially all of the
Company's nonregulated businesses. The decision to sell Mentor Information
Systems, Inc., Digital Systems, Inc., Stoner Associates, Inc., Kesler
Engineering, Inc. and American Tele/Response Group, Inc. occurred in September
1990 and the decision to sell PSC Engineers & Consultants, Inc. occurred in
March 1991 (the measurement dates). During 1991, all these businesses were sold
except for American Tele/Response Group, Inc. and Kesler Engineering, Inc.,
which were sold in the first quarter of 1993. The sale of the two companies in
1993 had no impact on the results of operations in 1993.
 
     As a result of deterioration in the operating results and backlog of future
work at the remaining businesses for sale during 1992, and a substantial
reduction in the estimated net proceeds from the ultimate disposition of the
businesses, a charge of $5,500 was taken in the third quarter of 1992 to reflect
the Company's revised estimate of the ultimate loss on the disposition of these
businesses. In the third quarter of 1991, a similar charge of $5,000 was taken
to reflect the then current estimate as to the ultimate outcome of the Company's
divestiture effort. Both charges were based on estimates which considered the
facts and circumstances known at the time the charges were taken, and included
projections of operating results through the expected disposition dates and
estimates of the net proceeds from the dispositions. Delays in finding suitable
buyers, further deterioration in operating performance and the resulting decline
in the estimated net proceeds from the disposition were the most significant
variations from the Company's previous projections as to the ultimate results of
the divestiture efforts. The timing and the net proceeds from the disposition of
the remaining two businesses and the operating losses during the period they
were owned by the Company were within the estimated reserves established in the
third quarter of 1992 and the Company does not foresee the need for any further
charges to income related to discontinued operations.
 
     Reserves related to discontinued operations cover future costs associated
with these operations, including administrative, legal and tax services,
contingent legal and lease obligations and certain employee costs. The notes to
the consolidated financial statements relate to continuing operations, except
where otherwise indicated.
 
     Financial information on the discontinued operations is as follows:

     Due to the sales of the companies during 1993 and 1991, the operating
results of the discontinued operations are not comparable for the three years
presented, since the operating results of the businesses sold are included only
for the periods prior to their sale.
 
     Operating expenses of the discontinued operations reflect allocated
interest charges of $271 and $1,162 in 1992 and 1991, and other costs of $773,
$228 and $1,697, which were specifically associated with these operations in
1993, 1992 and 1991, respectively. The effective tax rates of the discontinued
operations differ from statutory rates primarily because of the nondeductibility
of goodwill amortization in computing the taxable loss.

Income Taxes
 
     As noted in the Summary of Significant Accounting Policies footnote, the
Company adopted SFAS 109 as of January 1, 1993. Adoption of this standard
resulted in a net increase in deferred tax liabilities as of January 1, 1993 of
$47,399 which reflects deferred taxes that had previously not been recorded by
the water utility. Offsetting the net increase in deferred tax liabilities is a
regulatory asset of $46,480 and an increase in utility plant of $919. The
regulatory asset represents the expected recovery through future water rates of
the reversal of deferred taxes and investment tax credits. The increase in
utility plant reflects the interest component of AFUDC that was previously
accounted for net of tax. Consequently, there is no cumulative effect of this
change in the Consolidated Statement of Income for the year ended December 31,
1993. Prior years' financial statements have not been restated.
 
     Total income tax expense for the year ended December 31, 1993 is allocated
as follows:

     During 1992, the Company filed an application with the Internal Revenue
Service ('IRS') to change its tax accounting method with respect to interest and
overhead costs capitalized on utility plant construction. This application,
which was approved by the IRS, was made in order to place the Company in full
compliance with the uniform capitalization rules of the Internal Revenue Code,
which rules were enacted as part of the Tax Reform Act of 1986. As a result of
this change, the Company amended its 1991 tax returns to incorporate this change
for all utility plant constructed since 1986 and increased its taxable income
for 1991 by $2,548, the cumulative impact of the change on all prior years.
While the result of this change increased current tax expense by $1,073 in 1992,
the Federal tax portion was offset by a deferred tax benefit of $866. Since the
PUC does not allow the recovery of deferred state income taxes through rates,
$312 of additional state income taxes were recorded, which increased the
Company's effective tax rate in 1992 by 1.2%.

Commitments
 
     The water utility maintains agreements with the Chester Water Authority and
the Bucks County Water and Sewer Authority for the purchase of water in order to
supplement its water supply, particularly during periods of peak demand. The
agreements stipulate purchases of minimum quantities of water to the year 2017.
The estimated annual commitments related to such purchases total
approximately $2,637 through 1998. The water utility purchased approximately
$2,922 $2,649 and $3,006 of water under these agreements during the years ended
December 31, 1993, 1992 and 1991, respectively.
 
     The water utility leases motor vehicles and other equipment under operating
leases which are noncancellable and expire on various dates through 1997. During
the next five years, $1,191 of future minimum lease payments are due: $768 in
1994, $314 in 1995, $108 in 1996, and $1 in 1997. Rent expense was $1,134 $1,019
and $927 for the years ended December 31, 1993, 1992 and 1991, respectively.

(a) Provisions of the water utility's trust indenture and supplements thereto
    relating to these First Mortgage Bonds require sinking fund payments
    amounting to 1/2 of 1% of the maximum aggregate principal amount of these
    bonds outstanding. These sinking fund payments may be deferred until final
    maturity by certification to the Trustee of the net amount of available
    permanent additions to utility plant. All prior sinking fund requirements
    have been deferred by such certification and it is expected that they will
    be deferred in the same manner for the next five years.
(b) The supplemental trust indentures relating to these First Mortgage Bonds
    require annual sinking fund payments.
(c) The supplemental trust indentures relating to these First Mortgage Bonds
    require no annual sinking fund payments.

     The supplemental indentures with respect to certain issues of the Bonds
restrict the ability of the water utility to declare dividends, in cash or
property, or repurchase or otherwise acquire the water utility's stock. As of
December 31, 1993, approximately $51,000 of retained earnings were free of these
restrictions. Certain supplemental indentures also prohibit the water utility
from making loans to or purchasing the stock of the Company.
 
     Except for the amounts due under the water utility's revolving credit
agreement, the Company's sinking fund payments and debt maturities for the next
five years are as follows:

     In April 1993, the water utility issued $22,000 First Mortgage Bonds 7.15%
Series due 2008. Proceeds from this issue were used to fund the 1993 retirement
of the First Mortgage Bonds noted below and to repay amounts outstanding under
the water utility's revolving credit agreement. In June 1992, the water utility
issued $7,200 of First Mortgage Bonds in two series: $4,000 5.95%, due 2002 and
$3,200 6.5%, due 2010. The proceeds from these bonds were used to retire $7,200
First Mortgage Bonds 8.875% Series due 2010, at a premium of 2% or $144. The
unamortized bond issuance expenses related to the 1992 retirements were $90.
 
     In May 1993, the water utility retired $4,400 First Mortgage Bonds 10.125%
Series due 1995 and $3,150 First Mortgage Bonds 9.2% Series due 2001 at premiums
of .447% or $20 and 3.07% or $97, respectively. In August 1993, the water
utility retired $10,000 First Mortgage Bonds 12.45% Series due 2003 at a premium
of 5.12% or $512. The unamortized bond issuance expenses related to the 1993
retirements were $28. The premiums paid on the early retirement of debt, along
with the related unamortized bond issuance expense, were capitalized and are
being amortized, in accordance with the Uniform System of Accounts prescribed by
the PUC, over the life of the long-term debt used to fund the redemption.
 
     The water utility has a $22,000 revolving credit agreement due February
1994. The agreement had been amended to temporarily increase the available
borrowings under this facility by $10,000 from August 1992 to April 1993 when
proceeds were received from the issuance of bonds. Interest under this facility
is based, at the water utility's option, on the prime rate, an adjusted federal
funds rate, an adjusted certificate of deposit rate corresponding to the
interest period selected or an adjusted Euro-Rate corresponding to the interest
period selected. A commitment fee of 1/4 of 1% is charged on the unused portion
of the loan. The average cost of borrowing under this facility was 4.0 and 4.2%,
and the average borrowing was $11,723 and $9,011 during 1993 and 1992,
respectively.
 
     In February 1994, the water utility replaced its expiring revolving credit
facility with a $30,000 revolving credit agreement due March 1998. The terms of
the new facility and the interest rate selection are substantially the same as
the expiring facility. This agreement restricts the total amount of short-term
borrowings of the water utility. A commitment fee of 1/8 of 1% is charged on the
unused portion of the loan. The note payable to banks under the existing
revolving credit agreement has been classified as long-term debt since funds
under this new facility will be used to repay amounts outstanding under the
existing facility.
 
     In 1992, a 9% installment note payable for $1,777 was issued in connection
with the acquisition of the water utility assets of the Uwchlan Township
Municipal Authority. This note requires annual payments of $191 which consist of
both principal and interest.
 
                                       12
<PAGE>

     During 1992, the Company retired $25,000 of the 10.125% Debentures due July
1998 at a premium of 4.27% or $1,068. The premium, plus the write-off of the
associated bond issuance expense of $195, net of income tax benefits of $429,
have been classified as an extraordinary charge in the Company's Consolidated
Statements of Income.
 
     At December 31, 1993 and 1992, the Company and the water utility had
short-term lines of credit totaling $4,000. Funds borrowed under these lines are
classified as loans payable and are used to provide working capital. The average
borrowing under the lines was $393 and $686 during 1993 and 1992, respectively.
The maximum amount outstanding at the end of any one month
was $819 in 1993 and $2,190 in 1992. Borrowings are at the lesser of the prime
rate or an adjusted federal funds rate. In 1993 and 1992, a commitment fee of
1/4 of 1% was charged on the unused portion of the lines of credit. The average
cost of borrowings under all lines during 1993 and 1992 was 4.4% and 4.9%,
respectively.
 
     The total amount of interest paid on all borrowings, net of amounts
capitalized, was $13,327, $16,876 and $15,184 in 1993, 1992 and 1991,
respectively.
 
Fair Value of Financial Instruments
 
     The carrying amount of current assets and liabilities which are considered
financial instruments approximates their fair value as of the dates presented.
The carrying amounts and estimated fair values of the Company's long-term
financial liabilities as of December 31, 1993 are as follows:

Preferred stock of subsidiary with mandatory redemption...................       10,000       11,126
</TABLE>
 
     The fair value of long-term debt and preferred stock has been determined by
discounting their future cash flows using current market interest or dividend
rates for similar financial instruments of the same duration. The Company's
customers' advances for construction and related tax deposits have carrying
values of $24,379 and $6,179, respectively at December 31, 1993. Their relative
fair values cannot be accurately estimated since future refund payments depend
on several variables, including new customer connections, customer consumption
levels and future rate increases. Portions of these non-interest-bearing
instruments are payable annually through 2014, and amounts not paid by the
contract expiration dates become non-refundable. The fair value of these amounts
would, however, be less than their carrying value due to the non-interest
bearing feature.
 
Preferred Stock of Subsidiary with Mandatory Redemption
 
     In February 1991, the water utility issued 100,000 shares of 8.66% Series 1
Cumulative Preferred Stock, at par value of $100 per share in a private
placement. Dividends of this issuance are payable quarterly and are cumulative.
These shares are subject to mandatory redemption through an annual sinking fund
equal to the par value of 14,285 shares plus accrued dividends starting in 1995
and ending in 2001. The sinking fund requirements may be met by a direct
redemption of outstanding shares at par value plus any accrued dividends. The
water utility has the right to redeem all or a portion of the preferred stock at
a price above par beginning in 1995. Under the terms of the Stock Purchase
Agreement, the water utility may not pay dividends on its common stock unless
provision has been made for payment of the preferred dividends. As of December
31, 1993, all preferred dividends have been provided for. The water utility is
authorized to issue up to 1,000,000 shares of preferred stock, with stated par
value, in one or more series.

Net Income per Share and Equity per Common Share
 
     Net income per share is based on the weighted average number of common and
dilutive common equivalent shares outstanding during the year. Common equivalent
shares arise from stock options.
 
     Equity per common share was $11.89 and $10.88 at December 31, 1993 and
1992, respectively. These amounts were computed by dividing common
stock-holders' equity by the number of shares of common stock outstanding at the
end of each year.
 
Common Stockholders' Equity
 
     At December 31, 1993, the Company had 20,000,000 shares of common stock
authorized; par value $.50. Shares outstanding at December 31, 1993, 1992 and
1991 were 11,429,968, 9,831,824 and 8,034,496, respectively. Treasury shares
held at December 31, 1993, 1992 and 1991 were 135,472, 83,837 and 82,154,
respectively.
 
     At December 31, 1993, the Company had 1,770,819 shares of authorized but
unissued Series Preferred Stock, $1.00 par value.

     In April 1993, the Company issued 1,100,000 shares of its common stock
through a public offering, resulting in proceeds of $18,331, net of expenses.
The proceeds of the offering and the stock plans described below were used by
the Company to fund $29,000 of equity investments in the water utility during
1993.
 
     The Company has a Customer Stock Purchase Plan for the water utility's
customers, and a Dividend Reinvestment and Optional Stock Purchase Plan for
existing shareholders. Shares of common stock are sold at a five percent
discount from the current market value under the Dividend Reinvestment Plan.
Under these plans, 417,501, 1,737,461 and 243,019 shares of common stock were
sold providing the

<PAGE>

Company with $7,539, $25,191 and $3,317 of additional
capital, after expenses, during 1993, 1992 and 1991, respectively.
 
In August 1993, the Board of Directors approved a resolution authorizing the
Company to purchase, from time to time, up to 250,000 shares of its common stock
in the open market or through privately
negotiated transactions. The number of shares purchased by the Company, if any,
is limited to the number of shares sold under its Employee Stock Option Plans,
Customer Stock Purchase Plan or Dividend Reinvestment and Optional Stock
Purchase Plan. The purchase of shares has been authorized in order to offset the
dilutive effect on earnings per share of issuances of additional shares under
these plans. Funding for any stock purchases is not expected to have a material
impact on the Company's financial position. During 1993, 51,635 shares have been
purchased at a net cost of $992.
 
Shareholder Rights Plan
 
     The Company has a Shareholder Rights Plan designed to protect the Company's
shareholders in the event of an unsolicited unfair offer to acquire the Company.
Each outstanding common share is entitled to one Right which is evidenced by the
common share certificate. In the event that any person
acquires 25% or more of the outstanding common shares or commences a tender or
exchange offer which, if consummated, would result in a person or corporation
owning at least 30% of the outstanding common shares of the Company, the Rights
will begin to trade independently from the common shares and, if certain
circumstances occur, including the acquisition by a person of 25% or more of the
outstanding common shares, each Right would then entitle its holder to purchase
a number of common shares of the Company at a substantial discount. If the
Company is involved in a merger or other business combination at any time after
the Rights become exercisable, the Rights will entitle the holder to acquire a
certain number of shares of common stock of the acquiring company at a
substantial discount. The Rights are redeemable by the Company at a redemption
price of $.02 per Right at any time before the Rights become exercisable. The
Rights will expire on March 1, 1998, unless previously redeemed.
 
Employee Stock Plans
 
     The 1982 Stock Option Plan, which was terminated effective March 1988, was,
and the 1988 Stock Option Plan is intended to provide officers and other key
employees of the Company and its subsidiaries with an incentive in the form of a
proprietary interest in the Company. These plans provide for the granting of
qualified and nonqualified options to purchase the Company's common stock at not
less than 100% of the market price on the day of grant. No additional grants may
be made from the 1982 plan; 425,000 shares were reserved for grants under the
1988 plan. Generally, options are exercisable in installments of 20% annually
starting one year from the date of the grant and expire 10 years from the date
of the grant.
 
     The following table summarizes stock option transactions for both the 1982
and 1988 Plans:

     Options exercised during 1993 ranged in price from $11.46 per share to
$15.63 per share. The shares under option at December 31, 1993 are exercisable
at prices ranging from $12.88 to $17.13 per share. At December 31, 1993, 122,740
shares were exercisable, and 500 options were available for grant.
 
     The Executive Incentive Award Plan, as amended, awarded key executives and
senior managers incentive bonuses by allowing them to purchase a specified
number of shares of common stock at par value. Awards under the plan are subject
to vesting restrictions, generally five years from the date of issue. The plan
expired by its terms on December 31, 1991, but one previous grant remains
outstanding. At December 31, 1993 and 1992, 10,000 shares of stock were subject
to vesting restrictions.
 
Pension Plans and Other Postretirement and Postemployment Benefits
 
     The Company has defined benefit pension plans which cover the majority of
all full-time employees. Retirement benefits under the plans are generally based
on the employee's total years of service and compensation during the last five
years of employment. The Company's policy is to fund these plans annually at a
level which is deductible for income tax purposes and which provides assets
sufficient to meet its pension obligations. As a result of certain limitations
imposed by the Internal Revenue Code with respect to payments under qualified
plans, the Company, in 1989, adopted a nonqualified Excess Benefit Plan for
Salaried Employees in order to prevent certain employees from being penalized by
these limitations. The Company also has a Supplemental Executive Retirement Plan
for two employees. The net pension costs and obligations of these plans are
included in the tables which follow.
 
     The Company's pension expense includes the following components:

     The accumulated benefit obligation represents the actuarial present value
of benefits based on historical compensation and historical years of service.
The projected benefit obligation represents the actuarial present value of
benefits based on future projected compensation levels and historical years of
service. The unrecognized net obligation is being amortized over 15 years
starting January 1986 and the unrecognized prior service cost is being amortized
over 14 years starting January 1990.
 
     The accumulated and projected benefit obligations were calculated using the
projected unit credit method, and reflect the following assumptions: discount
rates of 7.00% for 1993, 8.00% for 1992 and 8.25% for 1991; increase in future
compensation levels of 5.5% for 1993 and 6.5% for 1992 and 1991; and long-term
rate of return on assets of 10% for 1993, 1992 and 1991.
 
     In addition to providing pension benefits the water utility offers certain
Postretirement Benefits other than Pensions ('PBOPs') to employees retiring with
at least 15 years of service. These PBOPs include continuation of medical and
prescription drug benefits for all eligible retirees and a life insurance policy
for eligible union retirees.
 
     In 1993, the water utility amended its postretirement medical and
prescription drug benefits for non-union employees adopting a graduated
eligibility schedule applicable to employees who had not met the eligibility
requirements of 15 years of service and at least 55 years of age to participate
in the plan as of December 31, 1993. Additionally, the 1993 amendments shift the
burden of excessive future medical inflation to such non-eligible employees as
the water utility's contribution toward the benefits is limited to a medical
inflation rate of no more than 5% per year.
 
     In January 1993, the Company adopted SFAS 106, 'Employers' Accounting for
Postretirement Benefits Other Than Pensions'. Under SFAS 106, the cost of PBOPs
is recognized on an accrual basis as employees perform services for the Company.
Prior to 1993, the costs for these benefits were recognized on a cash, or
'pay-as-you-go' basis.
 
     As of January 1, 1994, the Company's Accumulated Postretirement Benefit
Obligation ('APBO') related to SFAS 106 was approximately $15,580. The annual
1993 PBOP costs computed 

 
                                       17

under SFAS 106 are $2,260, which include a 20-year
amortization of the Company's APBO and $564 of 'pay-as-you-go' costs. The
Company's 1992 and 1991 PBOP costs computed under the 'pay-as-you-go' method
were $511 and $446, respectively. Costs computed under SFAS 106 for 1993
included the following components:

</TABLE>
 
     The water utility's current water rates include recovery of PBOP costs on
the 'pay-as-you-go' basis. In November, 1993, the PUC approved deferral of the
water utility's incremental SFAS 106 costs until such time as they are included
in the Company's base rates. In granting this approval, the PUC declared the
regulatory asset recorded pursuant to their decision allowable for ratemaking
purposes in Pennsylvania and concluded that the water utility was allowed to
make a claim to recover in rates both the annual SFAS 106 costs and the
regulatory asset. These acknowledgements, coupled with the PUC's 1993 actions to
approve SFAS 106 costs in other utility rate proceedings, provide sufficient
basis for the establishment of a regulatory asset in accordance with Statement
of Financial Accounting Standards No. 71, 'Accounting for the Effects of Certain
Types of Regulation' and the Financial Accounting Standards Board's ('FASB')
Emerging Issues Task Force consensus position. Accordingly, a regulatory asset
has been established for such deferrals. As a result, the adoption of SFAS 106
has had no effect on the Company's results of operations for 1993 and the
Company does not expect the adoption of this standard to have a significant
impact on future period operating results. In December 1993, the water utility
initiated a base rate filing with the PUC requesting, among other things,
recovery through water rates of its PBOP costs computed under SFAS 106,
including a five-year amortization of the SFAS 106 costs it has recorded as a
regulatory asset. The Pennsylvania Office
of Consumer Advocate has appealed other utility rate decisions to the
Commonwealth Court, when the PUC allowed rate recovery of the utility's
incremental SFAS 106 costs. If the Court should reverse the PUC decision, the
Company's 1994 SFAS 106 expense and all amounts previously
deferred would likely be charged to expense, reducing 1994 net income by
approximately $1,900.
 
     The APBO and the 1993 PBOP costs are calculated utilizing the following
assumptions: discount rate of 7%; medical inflation rates of 12%, reducing to 5%
in 1994 for those employees not eligible by December 31, 1993, and to 4.5% by
2002 for all others; and no return on plan assets. The effect of a 1% increase
in the assumed medical inflation rates would be to increase the APBO and the
1993 PBOP costs by $1,940 and $196, respectively.
 
     The Company has not begun funding its SFAS 106 liability and expects to do
so in conjunction with the inclusion of these costs in water rates, anticipated
in the third quarter of 1994.
 
     In November 1992, FASB issued Statement of Financial Accounting Standards
No. 112 'Employers' Accounting for Postemployment Benefits' ('SFAS 112'). Under
SFAS 112, the cost of postemployment benefits must be recognized on an accrual
basis as employees perform services for the Company. The costs for these
benefits are currently recognized at the time they are paid. Many of the
provisions and concepts of SFAS 112 are similar to current standards on
accounting for pensions and postretirement benefits. Historically, the Company
has experienced minimal postemployment medical costs and the Company has already
established adequate reserves for other costs which are accruable 

 
                                       74
<PAGE>

under this standard. Consequently, the implementation of SFAS 112 in the first 
quarter of 1994 is expected to have little or no impact on the results of 
operations or financial position of the Company.
 
Water Rates
 
     The water utility filed an application with the PUC on December 3, 1993
requesting a $14,000 or 14% increase in annual revenues. This application is
currently pending before the PUC and a final determination is anticipated before
September 1994.
 
     The water utility has been granted rate increases of 7.4% and 7.7%
effective June 1, 1993 and October 18, 1991, respectively. These increases were
calculated to provide annual revenues of approximately $6,750 and $6,530,
respectively. In addition to the general rate increases, the water utility, in
August 1991, was permitted to add a surcharge to its bills in order to recover
costs associated with Pennsylvania tax rate increases. The surcharge generated
additional revenue of $706, $2,281 and $1,292 in 1993, 1992 and 1991,
respectively. Effective June 1, 1993, the Company no longer added the surcharge
to its bills as the appropriate costs were included in the water rates which
took effect on that date.

                              MANAGEMENT'S REPORT
 
     The consolidated financial statements and related information for the years
ended December 31, 1993, 1992 and 1991 were prepared by management in accordance
with generally accepted accounting principles and include management's best
estimates and judgments, as required. Financial information included in other
sections of this annual report is consistent with that in the consolidated
financial statements.
 
     The Company has an internal accounting control structure designed to
provide reasonable assurance that assets are safeguarded and that transactions
are properly authorized and recorded in accordance with established policies and
procedures. The internal control structure is supported by the selection and
training of qualified personnel, the delegation of management authority and
responsibility and dissemination of policies and procedures.
 
     The Company's independent auditors, KPMG Peat Marwick, provide an
independent review of management's reporting of results of operations and
financial condition. KPMG Peat Marwick has audited the financial statements by
conducting tests as they deemed appropriate and their report follows.
 
     The Board of Directors through the Audit Committee selects the Company's
independent auditors and reviews the scope and results of their audits. The
Audit Committee also reviews the adequacy of the Company's internal control
structure and other significant matters. The Audit Committee is composed of
three outside Directors who meet periodically with management and the
independent auditors. The Audit Committee held two meetings in 1993.

                          INDEPENDENT AUDITORS' REPORT
 
The Stockholders and Board of Directors
Philadelphia Suburban Corporation:
 
     We have audited the accompanying consolidated balance sheets of
Philadelphia Suburban Corporation and subsidiaries as of December 31, 1993 and
1992, and the related consolidated statements of income, and cash flows for each
of the years in the three-year period ended December 31, 1993. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Philadelphia
Suburban Corporation and subsidiaries as of December 31, 1993 and 1992, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1993, in conformity with generally accepted
accounting principles.
 
     As discussed in the notes to the consolidated financial statements, the
Company changed its method of accounting for income taxes and postretirement
benefits other than pensions to adopt the provisions of Financial Accounting
Standards Board Statements of Financial Accounting Standards No. 109,
'Accounting for Income Taxes' and No. 106, 'Employers' Accounting for
Postretirement Benefits Other Than Pensions'.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
              (IN THOUSANDS OF DOLLARS, EXCEPT PER SHARE AMOUNTS)
 
General Information
 
     Philadelphia Suburban Corporation ('PSC' or the 'Company') is composed of
two businesses, a regulated water utility (Philadelphia Suburban Water Company
or 'PSW'), and a nonregulated data processing service bureau (Utility &
Municipal Services, Inc.). The service bureau operations are not significant to
the financial results of the Company and, therefore, are not discussed
separately. In 1990, the Board of Directors authorized the sale of Mentor
Information Systems, Inc., Digital Systems, Inc., American Tele/Response Group,
Inc., Stoner Associates, Inc., and its subsidiary Kesler Engineering, Inc.; and
in the first quarter of 1991, the Board of Directors authorized the sale of PSC
Engineers & Consultants, Inc. In 1991, the Company sold all of these businesses
with the exception of American Tele/Response Group, Inc. and Kesler Engineering,
Inc., which were both sold in early 1993. The results of operations of these
businesses during the period they were owned by the Company are accounted for as
discontinued operations. See Results of Operations - Discontinued Operations.

     Income from continuing operations of the Company has grown at an annual
compound rate of approximately 8.4% during the five-year period ended December
31, 1993. During this same period, revenues and total expenses, other than
income taxes, have grown at compound rates of 6.7% and 5.7%, respectively.
 
Earned Revenues
 
     Water revenues have accounted for approximately 98% of the Company's earned
revenues from continuing operations during the five-year period covered above.
The balance of the revenue from continuing operations is primarily associated
with data processing services that have remained relatively constant.
 
     The growth in water revenues over the past five years is primarily a result
of increases in rates and, to a lesser extent, an increase in customer base.
Revenues in 1993 also increased as a result of the December 1992 acquisitions of
two municipal water systems which provided water revenues of $2,052. Excluding
the 7,748 customers that were added as a result of the acquisitions in December
1992 and 1993, the customer base increased at a five-year annual compound rate
of .6%. This increase represents normal expansion within the water utility's
established 339-square-mile service territory. Water rates have increased by 32%
since 1989, reflecting an annual compound growth rate of 5.6% over the five-year
period.
 
     Rates charged by PSW for water service are subject to the approval of the
Pennsylvania Public Utility Commission ('PUC'). PSW continuously reviews the
necessity of filing applications with the PUC for increases in rates charged for
water service. Among the factors considered by management in determining the
need to apply for increased rates are: changes in the cost of capital and the
capital structure of PSW; increases in operating expenses (including wages,
fringe benefits, electric and chemical expenses), depreciation and taxes
experienced since the previous rate decision; and the amount of utility plant
additions and replacements made since the previous rate decision. Based on these
assessments, PSW will periodically file a request with the PUC to increase its
rates. Typically, the PUC will suspend the rate request for up to nine months
during which time hearings on the merits of the request are held. During these
hearings, the views of PSW as well as the PUC staff, the Consumer Advocate and
other interested parties are presented and evaluated.
 
                                     22
<PAGE>
     The return allowed on PSW's common equity is a major factor in the
determination of rates and is also evaluated before applying for a rate
increase. The return on common equity allowed by the PUC has declined in recent
years from 13.7% allowed in the 1988 increase. The 1991 rate increase, in which
a 12% return on common equity was allowed, was the most recent request that the
PUC specified a return on common equity for PSW. The rate increases which were
effective in June 1993 and September 1990 resulted from settlements, with PUC
approval, between the Company and the opposing parties and, as such, no
determination of the rate of return on common equity was made by the PUC.
 
     Over the past 10 years, PSW had applied for, and received the following
rate increases from the PUC:

     On December 3, 1993, PSW filed a request with the PUC to increase its rates
by 14% or $14,000 on an annual basis. Included in this filing is a requested
return on common equity of 11.9%. In January 1994, the PUC suspended this
request and hearings on the merits of the request are expected in March and
April of 1994. The PUC is anticipated to rule on the rate request by August
1994.
 
     In addition to the rate increases noted above, the PUC has adjusted rates
to reflect changes in the tax laws. Effective August 1991, PSW was allowed to
add a 4.1% surcharge to its bills in order to recover costs associated with an
increase in certain Pennsylvania tax rates. Initially, this surcharge allowed
PSW to recover during the seven-month period from August 1991 to March 1992,
most of the additional tax expenses that were incurred during the 15-month
period from January 1991 to March 1992. In accordance with PUC regulations, the
surcharge was recomputed to 2.03% for bills rendered from April 1992 to March
1993 and to 1.97% for bills rendered from April 1993 to May 1993, reflecting the
more timely recovery of these additional taxes. Recovery of the additional tax
expenses was incorporated into PSW's base rates which took effect on June 1,
1993 and the surcharge was no longer added to bills for water service subsequent
to that date. Revenues associated with the surcharge were $706 in 1993, $2,281
in 1992 and $1,292 in 1991.
 
     'Sendout' represents the quantity of treated water delivered to the
distribution system and is used by management as an indicator of customer
demand. Consumption per customer is the sendout that was used by metered
customers and is based on the actual bills rendered during the year adjusted for
the estimated unbilled customer usage. Over the past five years, an average of
approximately 81.9% of the sendout was consumed by metered customers. The
majority of the balance was used through unmetered fixed-rate fire hydrants,
lost through leaks in water mains or used by PSW in its operations. PSW's ratio
of metered customer use to total sendout is consistent with industry statistics.
The percentage of water consumed by metered customers was 83.4% in 1993, 82.2%
in 1992 and 82.3% in 1991. The improvement in the percentage of sendout consumed
by metered customers is associated with fewer main breaks, particularly in the
past three years when the winter months were less severe, PSW's leak detection
and water main rehabilitation programs, and an increase in the number of newer
and more accurate meters.
 
     In 1993, the average consumption per customer improved over 1992 but was
still slightly below the average for the years 1989 to 1991. While consumption
in 1993 improved significantly during the summer months, this improvement was
largely offset by decreases in consumption during the balance of the year. In
1992, average consumption decreased by 2.5% over 1991 and it is believed that
this
 
                                       23
<PAGE>

decrease was associated with the cool, wet weather experienced in the late
spring and early summer of that year. The recession, which impacted most classes
of customers, and conservation by customers also may have had an impact on
consumption in the past two years.
 
     Water consumption tends to be impacted by weather conditions, particularly
during the late spring and summer months when nonessential and recreational use
of water is at its highest. Consequently, a higher proportion of annual
operating revenues is realized in the second and third quarters. Except for
1992, the average annual consumption per customer over the past five years was
relatively constant. The spring and summer of 1992 were characterized by cooler
weather with frequent rains and consumption declined. It is difficult to
establish an exact correlation between the weather and water consumption, since
conservation and even day-to-day variations in weather patterns can have an
effect. Conservation efforts and mandated water use restrictions in response to
drought conditions in prior years have also had an effect on water consumption.
 
Operating Expenses
 
     Operating expenses of a water utility company may be grouped into the
general categories of collection, pumping, purification, distribution and
administration. These expenses for 1993, 1992 and 1991 totaled $44,480, $41,314
and $40,059, respectively. All elements of cost are subject to the effects of
inflation, as well as the effects of changes in water consumption and the degree
of treatment required due to variations in the quality of the raw water being
processed. The principal elements of operating costs are labor, electricity,
chemicals and maintenance expenses. Electricity and chemical expenses vary in
relationship to water consumption and raw water quality. Maintenance expenses
are sensitive to extreme cold weather, which can cause water mains to rupture.
 
     PSW's operating expenses increased in 1993 over 1992 by 7.7% due to
increased wages and employee benefit costs; operating expenses associated with
the December 1992 acquisitions and the cost to process and distribute the
increased volume of water sold. The increase in 1992 over 1991 of 3.1% was
associated with wage increases offset in part by reductions in variable costs
due to the reduction in water sales.
 
     Corporate costs related to continuing operations were 1%, 2% and 4% of the
Company's operating expenses in 1993, 1992 and 1991, respectively. Such expenses
include those unallocated general and administrative expenses associated with
maintaining a publicly-held company.
 
Depreciation and Amortization
 
     Depreciation expense was $9,927, $8,646 and $7,612 in 1993, 1992 and 1991,
respectively, and has increased principally as a result of the significant
capital expenditures made to expand and modernize the water utility plant.
Depreciation expense was approximately 2.2% of the average utility plant in
service for all years. Amortization expense, which was $1,008, $800 and $641 in
1993, 1992 and 1991, respectively, increased in each of the last two years due
to the frequency of rate request filings and a decrease in the time frame over
which those costs are amortized.
 
Taxes Other than Income Taxes
 
     Taxes other than income taxes increased by 6% in 1993 and by 7% in 1992
over the previous year. The majority of the increase in both years was
associated with increases in the bases on which the Pennsylvania Public Utility
Realty Tax (PURTA) and the Capital Stock Tax are calculated. The increase in
taxable base for the PURTA is due to the increases to utility plant over the
past two years, including the December 1992 and 1993 acquisitions, while the
increase in the Capital Stock Tax is due to the common equity raised over the
past two years.
 
                                       24
<PAGE>

Interest and Debt Expenses
 
     Interest expense was $13,108, $15,068 and $14,781 in 1993, 1992 and 1991,
respectively. The decrease in 1993 was due to reductions in total debt
outstanding, the refinancing in the past two years of certain First Mortgage
Bonds at PSW with lower-cost debt and reductions in interest rates on borrowings
under PSW's revolving credit facility. The Company was able to reduce its
average outstanding debt in 1993 with the proceeds it received from the sale of
common stock and the discontinued operations. Interest expense increased in 1992
over 1991 due to higher average borrowings during that year, offset in part by
lower interest rates on borrowings under PSW's revolving credit facility.
 
Allowance for Funds Used During Construction
 
     The allowance for funds used during construction ('AFUDC') was $805, $258
and $1,194 in 1993, 1992 and 1991, respectively, and has varied over the years
as a result of changes in the average balance of utility plant construction in
progress, to which AFUDC is applied, and, to a lesser extent, to changes in the
AFUDC rate.
 
     The average balance of construction in progress to which AFUDC is applied
was $8,379, $3,197 and $14,372 in 1993, 1992 and 1991, respectively. The
variances in these average balances are primarily due to a $32,700 water
treatment plant placed in service in mid-1991 and an $11,500 treatment plant
placed in service in November 1993. AFUDC was no longer applied to these
projects after they were placed in service but was applied to an ever-increasing
base during the period they were under construction. The average cost of capital
on which the AFUDC rate was based, has declined since 1991 reflecting similar
decreases in interest rates and the allowed return on PSW's common equity.
 
Income Taxes
 
     The Company's effective income tax rate was 43.0% in 1993 as compared to
43.1% in 1992 and 41.0% in 1991. The effective tax rate declined in 1993,
despite a 1% increase in the statutory federal tax rate, due to a reduction of
operating expenses at the parent company which are not deductible for state
income taxes. In 1992, the Company filed with the Internal Revenue Service
('IRS') a request to change its method of accounting with respect to interest
and overhead costs capitalized on utility plant construction. As a result of
this request, the Company incurred additional state income taxes which increased
the effective tax rate in 1992.
 
Discontinued Operations
 
     As a result of deterioration in the operating results and backlog of future
work at the discontinued operations during 1992, and a substantial reduction in
the estimated net proceeds from the ultimate disposition of the businesses, a
charge of $5,500 was taken in the third quarter of 1992 to reflect the Company's
revised estimate of the ultimate loss on the disposition of these businesses. In
the third quarter of 1991, a similar charge of $5,000 was taken to reflect the
then current estimate as to the ultimate outcome of the Company's divestiture
effort. Both charges were based on estimates, which considered the facts and
circumstances known at the time the charges were taken, and included projections
of operating results through the expected disposition dates and estimates of the
net proceeds from the dispositions. Delays in finding suitable buyers, further
deterioration in operating performance and the resulting decline in the
estimated net proceeds from the disposition were the most significant variations
from the Company's previous projections as to the ultimate results of the
divestiture efforts. The timing and the net proceeds from the disposition of the
two businesses sold in the first quarter of 1993, and the operating losses
during the period they were owned by the Company were within the estimated
reserves established in the third quarter of 1992 and the Company does not
foresee the need for any further charges to income related to the discontinued
operations. The balance of the reserves for discontinued operations were
established to cover future additional costs associated
 
                                       25
<PAGE>

with these operations, including administrative, legal and tax services;
contingent legal and lease obligations and certain employee costs.
 
Summary
 
     Operating income from continuing operations in 1993, 1992 and 1991 was
$37,430, $34,337 and $31,637, respectively, and income from continuing
operations was $13,835, $10,626 and $10,179, respectively, for the same periods.
On a per share basis, income from continuing operations in 1993, 1992 and 1991
was $1.27, $1.23 and $1.29, respectively. The increase in the per share income
from continuing operations in 1993 over 1992 was due to the aforementioned
improvements in profits offset in part by a 25.7% increase in the average number
of shares outstanding during the year.
 
     Although the Company has experienced increased income from continuing
operations in the recent past, continued adequate rate increases reflecting
increased operating costs and new capital investments are important to the
future realization of improved profitability. This in turn will provide the
level of internal funds necessary to expand and modernize the utility plant.
 
     Net income in 1993, 1992 and 1991 was $13,835, $4,292 and $4,889,
respectively. Net income in 1993 improved as compared to 1992 due to increased
income from continuing operations and to the absence of charges related to the
discontinued operations and the early retirement of debt. Net income in 1992
declined as compared to 1991 as a result of the losses related to the
discontinued operations and the extraordinary charge related to the early
retirement of parent company debt, offset by the improvement in income from
continuing operations.
 
Fourth Quarter Results
 
     Income from continuing operations for the fourth quarter of 1993 increased
by $562 to $3,387 primarily as a result of a $2,551 increase in revenues and
reduced interest expense during this period. The increase in revenues is a
result of the 7.4% rate increase which took effect in June 1993 and to a slight
increase in water sales during the quarter. The increase in revenues was
partially offset by higher operating expenses, income taxes, depreciation,
amortization and taxes other than income taxes. Operating expenses increased as
a result of an increase in variable costs associated with the increase in water
sales, wage increases, an increase in costs associated with main breaks and to
expenses related to the December 1992 acquisitions. Depreciation increased due
to utility plant additions made since the fourth quarter of 1992. Amortization
increased primarily due to the amortization of costs associated with the June
1993 rate increase. Taxes other than income taxes increased primarily because of
the increase in the base on which the PURTA and Capital Stock Tax are computed.
Interest declined in the fourth quarter primarily as a result of the retirement
of $25,000 of parent company debt in the second half of 1992 and lower interest
rates.
 
Recent Events
 
     In January and February 1994, the extreme cold weather experienced in PSW's
service territory caused an abnormally high number of water main breaks and as a
result, maintenance expenses have increased. In addition, sendout increased, and
while some of this increase is associated with the water main breaks, a portion
of the increase in sendout may be due to additional use by customers who allowed
water to run in order to keep pipes within their properties from freezing. Any
increase in revenues attributable to additional customer use will not be
determined until the end of the first quarter and consequently, the impact of
the weather on the results of operations during this period is unknown at this
time.
 
Effects of Inflation
 
     The effects of inflation on the Company during the past several years have
not been significant. As a regulated enterprise, PSW's rates are established to
provide recovery of costs and a return on its investment. Recovery of the
effects of inflation through higher water rates is dependent upon receiving
adequate and timely rate increases. However, rate increases are not retroactive
and often lag increases
 
                                       26
<PAGE>

in costs caused by inflation. During periods of moderate to low inflation, as
has been experienced for the past several years, the effects of inflation on the
water utility's operating results are not significant.
 
Regulatory Asset
 
     During the year, the Company adopted Statement of Financial Accounting
Standards No. 106, 'Employers' Accounting for Postretirement Benefits Other Than
Pensions' ('SFAS 106') and Statement of Financial Accounting Standards No. 109,
'Accounting for Income Taxes' ('SFAS 109'). These standards require PSW to
compute its income tax expense and its postretirement benefit costs other than
pensions ('PBOP') in a manner which differs from the computations used to
establish the recovery of expenses in the rate making process. A regulatory
asset was established during the year to defer the incremental costs related to
the adoption of the new standards and to recognize their expected recovery
through future water rates. During the year a regulatory asset of $51,229 was
recorded of which $1,696 relates to SFAS 106 and $49,533 relates to SFAS 109.
 
     The use of regulatory accounts is permitted by Statement of Financial
Accounting Standards No. 71 'Accounting for the Effects of Certain Types of
Regulation' ('SFAS 71'), which recognizes that the economic effects of
regulations on a utility can sometimes require accounting which is different
from that applied to enterprises in general in order for the financial
statements to be presented fairly. A recent interpretation of SFAS 71 by the
Emerging Issues Task Force of the Financial Accounting Standards Board ('FASB'),
whose positions are a source of generally accepted accounting principles
('GAAP'), indicates that the use of a regulatory asset to offset the impact of
costs computed under SFAS 106 is appropriate only if certain conditions are met.
Primary among these conditions is the assessment that it is probable that the
PUC will allow costs as defined by SFAS 106, including amounts previously
deferred, to be recovered in the rates the Company charges its customers.
 
     The Company's rate request filed on December 3, 1993 includes costs
computed under SFAS 106. In addition, during 1993, PSW requested and was granted
PUC approval to record the regulatory asset as it relates to SFAS 106. In
granting the request, the PUC declared the regulatory asset recorded pursuant to
their decision allowable for ratemaking purposes and concluded that the water
utility was allowed to make a claim to recover in rates both the annual SFAS 106
costs and the regulatory asset. These acknowledgements, coupled with the PUC's
1993 actions to approve SFAS 106 costs in other utility rate proceedings,
provide sufficient basis for the establishment of a regulatory asset for the
excess costs computed under SFAS 106.
 
     In 1993, the Pennsylvania Office of Consumer Advocate, in response to the
PUC's approval of other utility requests for deferral or recovery of SFAS 106
costs, appealed selected cases to the Commonwealth Court. Should the Court
reverse the PUC's approval, the Company would likely cease deferring any cost
associated with SFAS 106 and all amounts previously deferred would be expensed.
However, since the Company does not intend to fund the excess of its SFAS 106
cost over the pay-as-you-go-cost if rate recovery is not provided, cash flow
from operations will not be impacted.
 
     Income tax expense recognized in the rate making process has generally been
limited to current tax expense plus deferred Federal taxes as they related to
certain depreciable assets. The PUC has generally not recognized deferred income
tax expenses related to any state tax or on other differences between book and
taxable income. As a result, tax expense for rate making purposes has been
reduced resulting in rates which have been lower than they would have been had
financial accounting standards been used in establishing rates. Management
believes that the PUC will continue to follow its practice of allowing rate
recovery of current taxes and accordingly, recovery of the additional taxes
included in the regulatory asset will occur as the temporary differences
reverse.

</TABLE>
 
     Of the $135,117 in capital expenditures made in the past five years,
$134,800 results from PSW's construction program. Included in PSW construction
expenditures are: $44,200 for the construction of two surface water treatment
plants; $18,684 for new water mains; and $16,750 for the rehabilitation of
existing water mains. During this five year period, PSW received $16,152 of
advances and contributions in aid of construction to finance new water mains. In
addition to its capital program, PSW has made sinking fund contributions
aggregating $5,850, replaced $40,981 of debt and has refunded $10,444 of
customer advances for construction over the past five years and expended $10,451
related to the December 1993 and 1992 acquisitions of three municipal water
systems.
 
     Since net operating cash flow to PSW plus advances and contributions in aid
of construction have not been sufficient to fully fund its cash requirements,
PSW issued approximately $69,000 of long-term debt during the past five years,
$10,000 of preferred stock in 1991 and received $29,000 of equity investments
from the Company during 1993.
 
     The Company funded its investment in PSW and the repayment of approximately
$35,000 of its debt in 1991 and 1992 with the proceeds from the sale of common
stock and the sale of its discontinued operations. In April 1993, the Company
sold 1,100,000 shares of common stock in a public offering for net proceeds of
$18,331. The Company has also sold 2,909,343 shares of common stock for net
proceeds of $42,248 since 1989 through three plans that allow existing
shareholders and customers of PSW to purchase shares of common stock directly
from the Company. The following table provides the net proceeds to the Company
and the shares issued under these plans:

     Proceeds from the Customer Stock Purchase Plan ('CSPP') increased
dramatically in 1992 and, in order to better match future equity additions with
the need for additional capital, the Company amended this Plan in 1993 to
eliminate the 5% discount it previously offered customers and limited future
stock sales under this Plan to approximately 100,000 shares in each of the three
subscription periods during the year. The Dividend Reinvestment Plan ('DRP')
continues to offer a 5% discount to participants of this Plan.
 
     PSW's 1994 capital program, exclusive of the costs of new mains financed by
advances and contributions in aid of construction, is estimated to be $27,115
which is expected to be financed, along with $850 of sinking fund obligations
and $4,034 of debt maturities, through internally-generated funds, a revolving
credit facility, equity investments from the Company, and issuance of new long-
term debt. PSW has also submitted a proposal to acquire a municipal water system
contiguous to its existing service territory for a purchase price in excess of
$20,000. The proposal is currently being evaluated by the municipality and, if
accepted, it is anticipated that the acquisition would be completed in the
second half of 1994. This acquisition would be funded initially with short-term
debt with subsequent repayment from the proceeds of long-term debt and issuance
of new equity.
 
     Future utility construction in the period 1995 through 1998, including
recurring programs, such as the ongoing replacement of water meters, the
rehabilitation of water mains and additional transmission mains to meet customer
demands, exclusive of the costs of new mains financed by advances and
contributions in aid of construction, is estimated to require aggregate
expenditures of approximately $100,000. The Company anticipates that
approximately 50%of these expenditures will require external financing,
including additional investments from the Company. The estimates discussed above
do not include any amounts for possible future acquisitions of water systems or
the financing necessary to support them.
 
     PSW's ability to finance its future construction programs depends on its
ability to attract the necessary external financing and maintain or increase
internally-generated funds. Rate orders permitting compensatory rates of return
on invested capital and timely rate adjustments will be required to allow PSW to
achieve an adequate level of earnings to enable it to attract capital, maintain
satisfactory debt coverage ratios and maintain the water utility's financial
position at a level sufficient to secure attractively priced capital.
 
     Operating cash flow from the water utility along with external financings
will enable the Company to pursue its capital expenditure programs, pay
dividends and supply the working capital required by the Company in 1994.
Management believes, that with the improvement in the Company's
 
                                       29

capitalization ratios over the past two years, it will be able to obtain the
external financing that it will need.

</TABLE>
 
     The changes in the capitalization ratios result from the issuance of common
stock over the past five years, preferred stock in 1991, the retirement of
parent company debt in 1992 and 1991 and the issuance of debt by PSW to finance
its capital program.
 
Impact of Recent Accounting Pronouncements
 
     In November 1992, the FASB issued Statement of Financial Accounting
Standards No. 112, 'Employers' Accounting for Postemployment Benefits' ('SFAS
112') which requires the Company to accrue the expected cost of providing
postemployment benefits during the years that employees render services to the
Company. The Company intends to adopt this standard as required in the first
quarter of 1994. Historically, the Company has experienced minimal
postemployment medical costs and the Company has already established adequate
reserves for other costs which are accruable under this standard. Consequently,
the implementation of SFAS 112 is expected to have little or no impact on the
results of operations or financial position of the Company.

4% to $1.08 beginning with the June 1993 dividend.

ITEM 9. UNDERTAKINGS.
 
(a) The undersigned registrant hereby undertakes:
 
    Insofar as indemnification for liabilities rising under the Securities Act
    of 1933 (the 'Securities Act') may be permitted to directors, officers or
    persons controlling the registrant pursuant to the provisions described in
    this registration statement, or otherwise, Philadelphia Suburban Corporation
    (the 'Company') has been advised that in the opinion of the Commission such
    indemnification is against public policy as expressed in the Securities Act
    and is therefore unenforceable. In the event that a claim for
    indemnification against such liabilities (other than the payment by the
    Company of expenses incurred or paid by a director, officer or controlling
    person of the Company in the successful defense of any action, suit or
    proceeding) is asserted by such director, officer or controlling person in
    connection with the securities being registered, the Company will, unless in
    the opinion of its counsel the matter has been settled by controlling
    precedent, submit to a court of appropriate jurisdiction the question
    whether such indemnification by it is against public policy as expressed in
    the Securities Act and will be governed by the final adjudication of such
    issue.
