                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 - Summary of Significant Accounting Policies

Organization  - Middlesex  Water  Company  (Middlesex  or Company) is the parent
company and sole shareholder of Tidewater Utilities, Inc. (Tidewater), Pinelands
Water Company, Pinelands Wastewater Company and Utility Service Affiliates, Inc.
(USA). Public Water Supply Company,  Inc. (Public) and White Marsh Environmental
Systems,  Inc.  are  wholly-owned   subsidiaries  of  Tidewater.  The  financial
statements for Middlesex and its wholly-owned subsidiaries  (Consolidated Group)
are reported on a consolidated basis. All intercompany accounts and transactions
have been eliminated.

The  consolidated  notes  accompanying the 1997 Form 10-K are applicable to this
report  and,  in  the  opinion  of  the  Company,  the  accompanying   unaudited
consolidated  financial  statements contain all adjustments  (consisting of only
normal recurring accruals) necessary to present fairly the financial position as
of September 30, 1998 and the results of  operations  and its cash flows for the
periods ended September 30, 1998 and 1997.  Information  included in the Balance
Sheet as of  December  31,  1997 has been  derived  from the  Company's  audited
financial  statements  included  in its annual  report on Form 10-K for the year
ended December 31, 1997.

Note 2 - Regulatory Matters

On September 17, 1998,  Middlesex  filed a petition with the New Jersey Board of
Public  Utilities  (BPU) for a base rate  increase  of $7.9  million  or 2 1.9%.
Approximately  75% of the increase is necessary to recover the investment in the
upgrade and  expansion  of the Carl J. Olsen Water  Treatment  Plant (CJO Plant)
serving  our  Central  New Jersey  water  system.  The  purpose of the CJO Plant
upgrade is to meet the new and anticipated regulatory standards concerning water
quality, as well as to increase the plant's production  capacity.  A decision by
the BPU is expected in the summer of 1999. In January 1998,  Middlesex  received
approval  from the BPU for an overall  rate  increase of 4.4% or a $1.5  million
based on an original petition tiled in November 1996.

Note 3 - Capitalization

Common  Stock - On September 9, 1998,  Middlesex  filed a petition  with the BPU
seeking  approval  to issue up to  525,000  shares  of its no par  common  stock
through  a  public  offering.  A  decision  is  expected  in  November  1998.  A
registration  statement on Form S-3 is expected to be filed on or about the same
date as the Form 10-Q for the quarter ended September 30, 1998.

During the three months ended  September  30, 1998,  23,652  common  shares (0.3
million) were issued under the Company's  Restricted Stock Plan and the Dividend
Reinvestment and Common Stock Purchase Plan.

Long-term  Debt In November  1998, the Company will close on a BPU approved $2.2
million,  20 year  loan  from  the  State  of New  Jersey  and  the  New  Jersey
Environmental  Infrastructure  Trust (Trust).  The proceeds will he used to fund
the 1999 capital project to clean and cement line  previously  unlined pipes and
mains. The State loan of $l.05 million will come from the New Jersey  Department
of  Environmental  Protection,  which is funded under a Federal grant program to
finance  projects  that  improve  water  quality.  This  portion  of the loan is
interest free.





The Trust loan of $1.15 million will carry a coupon  interest rate that averages
approximately  4.50%.  The weighted rate for this  combination  of loans will be
about 2.35%.  The Company has delivered in escrow two Mortgage Bonds to evidence
these loans.

Note 4-- Commitments

The Company  has formed a new  subsidiary,  Utility  Service  Affiliates  (Perth
Amboy), Inc. (USA-PA), which is negotiating a 20-year agreement with the City of
Perth Amboy,  New Jersey  (Perth  Amboy) and the  Middlesex  County  Improvement
Authority (MCIA) to operate and maintain the water and wastewater systems of the
municipality. Perth Amboy has a population of 40,000 and has approximately 9,500
customers,  most of whom are  served by both  systems.  The  agreement  is being
effected under New Jersey's Water Supply Public/Private  Contracting Act and the
New Jersey  Wastewater  Public/Private  Contracting  Act.  Under the  agreement,
USA-PA would  receive a fixed fee and a variable  fee based on increased  system
billing. Fixed fee payments begin at $6.4 million in the first year and increase
to $9.7 in year 20. The agreement  would also require USA-PA to lease from Perth
Amboy all of its  employees  who  currently  work on the Perth  Amboy  water and
wastewater systems. In connection with the agreement,  the MCIA will issue up to
$69.5  million  in three  series of  bonds.  One of those  series  of bonds,  in
principal  amount up to $27.5 million,  is to be guaranteed by the Company.  The
other series of bonds are to be  guaranteed  by Perth Amboy.  The  agreement and
related  financing  have  received  the  approvals of the BPU and the New Jersey
Department of Community  Affairs-Local Finance Board. If the agreement goes into
effect,  USA-PA may enter into a subcontract  with a sewer  contracting firm for
the  operation  and  maintenance  of the Perth  Amboy  wastewater  system.  This
potential contract would result in certain sharing of fixed and variable fees as
well as the leased employees.

Liquidity and Capital Resources


The  table  below  presents  the  estimated  capital  expenditures  for  all our
companies for 1998, 1999 and 2000:

Our plan to finance  these  projects is well  underway.  Proceeds from the $23.0
million  Series W First  Mortgage Bond issued in March 1998 and the  anticipated
common stock offering will be used to finance the CJO Plant expenditures in 1998
and 1999.  Our Middlesex  system will receive $2.2 million from New Jersey State
Revolving Fund to cover the cost of the 1999 RENEW Program, which is our program
to clean and line with  cement  nine  miles of  unlined  mains in the  Middlesex
system.  There is a total of approximately 170 miles of unlined mains in the 670
mile Middlesex System. We expect to apply for similar funds in 1999 for the year
2000 RENEW Program.

The financing of our Delaware subsidiaries capital program will be a combination
of a capital  contribution  from  Middlesex and long-term  debt  financing  from
either a financial institution or Middlesex. The debt financing decision will be
based upon the terms of financing  available to our  Delaware  subsidiaries.  We
anticipate that we may file with the Delaware Public Service  Commission  during
1999 for a rate increase for Tidewater Utilities, Inc.

We expect to be able to cover the costs of  scheduled  upgrades to the  existing
systems with the cash flow  generated  from our utility  operations  through the
year 2000. For the nine months ended, our consolidated  group has expended $18.8
million for capital projects, including $12.2 for the CJO Plant.

From time to time it may be  necessary  to  utilize  the $28.0  million in total
lines of  credit we have  available  with  three  commercial  banks for  working
capital purposes or provide interim funds until long-term financing is arranged.
At September  30, 1998, we had $4.5 million of loans  outstanding  against those
lines of credit.

Regulatory Matters

On September 17, 1998,  Middlesex  filed a petition with the New Jersey Board of
Public  Utilities  (BPU)  for a base rate  increase  of $7.9  million  or 21.9%.
Approximately 75% of the increase is





necessary to recover the  investment in the upgrade and expansion of the Carl J.
Olsen Water  Treatment  Plant (CJO Plant)  serving our Central New Jersey  water
system.  The purpose of the CJO Plant upgrade is to meet the new and anticipated
regulatory  standards  concerning  water  quality,  as well as to  increase  the
plant's production  capacity. A decision by the BPU is expected in the summer of
1999. 

On January 29,  1998,  the BPU approved an increase in the rates of Middlesex by
4.4% or $1.5 million.  The original  petition was filed in November 1996.  Under
the  approval,  the  allowed  return on equity is 11.0% with an overall  rate of
return of 8.56%.  The increase  includes the recovery of  post-retirement  costs
other than pension expenses which are mandated by the Company's  compliance with
Statement of Financial Accounting Standards No. 106, "Employers' Accounting for
Postretirement Benefits Other Than Pensions."

In January 1997, the BPU approved a stipulation  agreed to by the parties to the
Pinelands  Water and  Wastewater  Companies'  rate  cases  which  were  filed in
February  1996. The  stipulations  allow for a combined rate increase which will
result in $0.4 million additional revenues. The new rates will be phased in over
a three-year period to minimize the impact on customers. Phases one and two were
implemented in January 1997 and 1998, respectively.

Accounting Standards

In February  1997,  the  Financial  Accounting  Standards  Board  (FASB)  issued
Statement of Financial Accounting Standards No.128,  "Earnings Per Share," (SFAS
No.128). This statement supersedes Accounting Principles Bulletin Opinion No.15,
"Earnings Per Share," and simplifies the reporting and computing of earnings per
share  (EPS).  SFAS  No.128  requires  dual  presentation  of basic and  diluted
earnings  per  share  on the  face  of  the  income  statement  and  requires  a
reconciliation  of the basic EPS computation to the diluted EPS computation.  At
December  31,1997,   the  Company  adopted  SFAS  No.128.  See  Note  5  to  the
Consolidated Financial Statements.

Statement  of  Financial   Accounting   Standards   (SFAS)  No.130,   "Reporting
Comprehensive  Income"  establishes  standards  for  reporting  and  display  of
comprehensive  income  and  its  components  in a full  set  of  general-purpose
financial statements. At September 30, 1998, the Company does not have any items
of comprehensive income that would affect the current reporting of the Company's
financial position, results of operations or cash flows.

SFAS  No.131,   "Disclosures   about  Segments  of  an  Enterprise  and  Related
Information,"  requires that public enterprises report certain information about
operating segments in complete sets of financial  statements.  Disclosure is not
required  for  interim   financial   statements  in  the  initial  year  of  its
application.  The Company is evaluating the requirements of SFAS No.131. Because
the  statement  relates  solely to disclosure  provisions,  it will not have any
effect on the Company's financial position, results of operations or cash flows.

SFAS No. 132,  "Employers'  Disclosures about Pensions and Other  Postretirement
Benefits,"  revises and  standardizes  disclosure  requirements  for pension and
other post-retirement benefit





plans but does not change the  measurement or  recognition of those plans.  This
Statement  is required to be adopted  for the fiscal  year ending  December  31,
1998.

Year 2000

Software  used in many computer  systems and  computerized  control  devices was
designed to record only the last two digits of each year. This software, some of
which the Company owns, may not function  properly as of January 1, 2000 because
it interprets  the new year as 1900.  The Company has evaluated its own computer
systems to make certain that those systems work properly when 1999 becomes 2000.
The Company has also requested  certification  of Year 2000  compliance from the
principal vendors of data processing serving its financial  reporting,  payroll,
billing,  customer  information  and  shareholder  record systems and the vendor
installing the new Supervisory Control and Data Acquisition system (SCADA).  The
vendors  have  certified  that  their  systems  have been  tested  and will work
properly.  The Company believes it may reasonably rely on those  certifications.
The Company also expects to spend up to $10,000 to bring other operating systems
including its network of desktop personal computers,  into Year 2000 compliance.
Nonetheless,  the Company may not have  identified  every  computerized  control
device  of the  Company's  which  may be  affected  by the  Year  2000.  Even if
identified,  the Company may not be able to reprogram or replace  those  devices
before January 1, 2000. More  importantly,  the Company cannot assess the impact
on the  Company of failures of  computer  systems  and control  devices  used by
others.  The Company is  especially  concerned  about third  parties who provide
significant services and materials to process, treat and distribute water and to
process,  treat and dispose of  wastewater,  and about the  possible  failure of
electric  power and  telecommunications  or the inability' to obtain diesel fuel
for  the  Company's  stand-by  generators.  The  occurrence  of  any  such  Year
2000-related  problem  could have a  material  adverse  effect on the  Company's
financial condition and results of operations.

Forward Looking Information

Certain  matters  discussed  in this  report on Form  10-Q are  "forward-looking
statements"  intended to qualify for safe harbors from liability  established by
the  Private  Securities  Litigation  Reform Act of 1995.  Such  statements  may
address future plans,  objectives,  expectations and events  concerning  various
matters such as capital expenditures,  earnings,  litigation,  growth potential,
rate  and  other  regulatory  matters,   liquidity  and  capital  resources  and
accounting  matters.  Actual results in each case could differ  materially  from
those  currently  anticipated  in such  statements.  The Company  undertakes  no
obligation to publicly update or revise any forward-looking statements,  whether
as a result of new information, future events or otherwise.

Results of Operations - Nine Months Ended September 30, 1998

Operating  Revenues  for the nine  months  ended  September  30,  1998 were $2.2
million higher than last year. Rate increases resulted in additional revenues of
$1.2 million.  The Middlesex  System received  regulatory  approval from the New
Jersey  Board of Public  Utilities  (BPU) to  implement a 4.4% rate  increase in
January 1998. The Pinelands Water and Wastewater  Companies also increased their
rates in January 1998. This increase represented the second part of a three part
rate increase  previously  approved by the BPU.  The third increase is scheduled
for January 1999.

A subsidiary  acquisition  added $0.6 million to revenues.  The  acquisition  of
Public Water





Supply  Company,  Inc.  (Public)  by  our  wholly-owned  subsidiary,   Tidewater
Utilities,  Inc.  (Tidewater)  was completed on July 31, 1997. As a result,  the
nine months of consolidated  revenue for 1997 only include two months of revenue
from Public.

Customer  growth  contributed  $0.4  million to revenues.  The customer  base of
Tidewater grew by 820 accounts over the twelve month period ended  September 30,
1998.  This  translates to an annual growth rate of 11.6% and is consistent with
the increase of 13.0% in water services billed to the customers of Tidewater.

Operating  Expenses  rose $ 1.7  million  or 7.2%  for  the  nine  months  ended
September 30, 1998. Some of the reasons for this increase are briefly  discussed
here. The Middlesex  System changed the composition of the water sources it used
to supply its  customers.  During  1998 less water was  withdrawn  from its well
fields and more was purchased from the New Jersey Water Supply Authority and the
Elizabethtown  Water Company.  This resulted in higher purchased water costs and
higher chemicals expense of $0.2 million. Electric power costs for the Middlesex
System were higher by about $0.2 million over last year due primarily to a large
credit we received in the 1997 period from our power provider.  Costs associated
with the  recognition of post  retirement  benefits  under  mandated  accounting
standards pushed operating expenses up by $0.3 million.  With the acquisition of
Public,  their  expenses are now included in our  consolidated  expenses.  Their
expenses amounted to $0.3 million for the nine months ended September 30, 1998.

On a consolidated  basis almost $9.5 million of newly constructed  utility plant
or utility  plant  acquired  through  acquisition  was  placed in service  since
September 30, 1997.  This resulted in higher  depreciation  expense in the first
nine months of 1998 of $0.2 million or 8% over that period last year.

Taxes other than income  taxes  includes  the taxes that the State of New Jersey
charges  regulated  water and wastewater  utilities based upon gross receipts of
operations  in New Jersey.  These taxes are called Gross  Receipts and Franchise
Taxes.  In general,  for every dollar of revenue  collected  from our New Jersey
customers  approximately  13.5%  is  remitted  to the  State of New  Jersey.  As
described above,  about $1.2 million of additional  revenues was recorded by our
New Jersey  companies which in turn increased the tax expense by just under $0.2
million.

Other income  increased  $0.7 million in the first nine months of 1998 over last
year. One of the components of the increase is higher earnings on the unexpended
proceeds from the Series W Mortgage  Bonds issued in March 1998. As of September
30, 1998, $11.3 million of the $23.0 million received from the Series W offering
remains in a CJO Plant Construction  account maintained by a trustee.  We submit
payment requisitions to the trustee for qualified CJO Plant expenditures.  It is
our  expectation  that the balance of the proceeds will be exhausted by February
1999. Another piece of the increase pertains to interest  capitalized on the CJO
Plant work in process expenditures.  Public utilities refer to this as Allowance
for Funds Used During Construction  (AFUDC). In general,  AFUDC is recorded as a
cost of the  project  until the  utility  plant is ready to  provide  service to
customers.  The  effect is to reduce  expenses  currently  for the  Company  and
depreciate the  capitalized  interest along with the rest of the CJO Plant costs
over its estimated useful life.

Interest  charges rose $0.5  million  which  represents  our  obligation  to pay
interest on those





Series W Mortgage Bonds.

Net Income for the nine months ended  September 30, 1998  increased $0.7 million
or 15.6% over the comparable  1997 period based upon the discussion  above.  The
increase in the preferred  stock  dividend  requirement is  attributable  to the
issuance of preferred  stock in July 1997 to complete the acquisition of Public.
Through  September  1998 nine months  worth of the  dividend  requirements  were
recorded while for the same period in 1997 only two months were recorded.

Basic and Diluted  Earnings  per Share both  increased  by $0.11 over last year.
There is a $0.01 per share  difference  between  Basic and Diluted  Earnings per
Share.  This difference is due to the two series of convertible  preferred stock
that we have issued.


Results of Operations - Three Months Ended September 30, 1998

Operating Revenues in the third quarter increased $1.1 million or 10.1% compared
to the same period in 1997.  Rate  increases  resulted in additional  revenue of
$0.5 million.  The inclusion of Public in consolidated  operations for the third
quarter  contributed  additional revenue of $0.2 million over 1997,  Consumption
increases for both Middlesex  residential  customers and a contract customer, as
well as growth in Tidewater's  customer base,  accounted for $0.4 million of the
higher revenues.

Total Operating Expenses rose $0.8 million or 9.2% for the third quarter.  These
increases  are  partially  the  result  of  higher  operations  and  maintenance
expenses.  Purchased  water and  electric  power each rose $0.1  million.  Water
treatment  costs and mandated  recognition  of accrued  post-retirement  benefit
costs other than pensions also  increased $0.1 million each and the inclusion of
Public's expenses added $0.2 million.

Depreciation  for the third  quarter  increased  9.6%. On a  consolidated  basis
almost $9.5 million of newly constructed utility plant or utility plant acquired
through acquisition was placed in service since September 30, 1997.

Taxes other than Income Taxes increased $0.1 million due to higher revenue based
taxes.  Federal Income Taxes  decreased $0.1 million for the quarter as a result
of a deferred tax benefit related to increased capitalized interest.

Other income  increased  $0.4 million for the quarter over last year. One of the
components of the increase is higher  earnings on the  unexpended  proceeds from
the Series W Mortgage Bonds.  Another piece of the increase pertains to interest
capitalized on the CJO Plant work in process expenditures.

Interest  charges rose $0.3  million  which  represents  our  obligation  to pay
interest on those Series W Mortgage Bonds.

Net Income for the three months ended  September 30, 1998 increased $0.5 million
or 24.0% over the comparable  1997 period based upon the discussion  above.  The
increase in the preferred  stock  dividend  requirement is  attributable  to the
issuance of preferred





stock in July 1997 to complete the acquisition of Public.  Only two months worth
of the dividend requirements were recorded for the third quarter of 1997.

Basic Earnings per Share increased by $0.09 over last year and Diluted  Earnings
per  Share  increased  by $0.08  over  last  year.  There is a $0.01  per  share
difference  between  Basic and Diluted  Earnings per Share for the quarter ended
September 30, 1998.
