                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization  - Middlesex  Water Company  (Middlesex)  is the parent company and
sole  shareholder of Tidewater  Utilities,  Inc.  (Tidewater),  Pinelands  Water
Company,  Pinelands Wastewater Company, Utility Service Affiliates,  Inc. (USA),
and Utility Service Affiliates (Perth Amboy) Inc. (USA-PA).  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  (the Company) are reported on a consolidated  basis.
All intercompany accounts and transactions have been eliminated.

The  consolidated  notes  accompanying the 1998 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, 1999 and the results of  operations  and its cash flows for the
periods ended September 30, 1999 and 1998.  Information  included in the Balance
Sheet as of December 31,  1998,  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, 1998.

NOTE 2 - REGULATORY MATTERS

On  September  20,  1999,  Tidewater  Utilities,  Inc.  and Public  Water Supply
Company,  Inc.  jointly  filed a  petition  with  the  Delaware  Public  Service
Commission (PSC) for a base rate increase of $1.7 million or 38.3%. The increase
is necessary to cover additional  capital  improvements and increased  operating
and maintenance costs. As prescribed by PSC regulations, Tidewater has requested
an interim rate increase,  subject to refund, of 14.8%,  effective  November 19,
1999.  The  PSC is  expected  to  address  this  issue  on  November  16,  1999.
Concurrently  with the rate  increase  request,  an  application  was  filed and
approved by the PSC for a corporate  merger of  Tidewater  and Public.  The last
increase  in base  rates  for  Tidewater  and  Public  were in  1991  and  1992,
respectively.  A rate  decision by the PSC is expected in the second  quarter of
2000.

NOTE 3 - CAPITALIZATION

COMMON STOCK - During the three months ended  September 30, 1999,  19,582 common
shares ($0.3 million) were issued under the Company's  Restricted Stock Plan and
Dividend Reinvestment and Common Stock Purchase Plan.

PREFERRED  STOCK - In  September,  the  number of  authorized  Preferred  Stock,
without par value,  was reduced from 149,980 shares to 148,980 shares to account
for the  election to exercise  the  conversion  privilege of 1,000 shares of the
$8.00 Series into 6,857 shares of the Company's common shares.

LONG-TERM  DEBT - On November 5, 1999, the Company closed on a BPU approved $4.5
million,  20 year  loan  from  the  State  of New  Jersey  and  the  New  Jersey
Environmental   Infrastructure  Trust  (Trust)  through  the  New  Jersey  State
Revolving Fund. The loan, which is secured by First Mortgage Bonds designated as
Series Z and AA, is comprised of a $2.15  million zero interest  borrowing  from
the New  Jersey  Department  of  Environmental  Protection  and a $2.35  million
borrowing  from the Trust with the  interest  rate varying from 5.25% to 5.75 %,
depending on the maturity date. Final maturity for both series of Mortgage Bonds
is August 1, 2019.  The interest paid to bond holders is exempt from federal and
New Jersey incomes  taxes,  but is subject to the  Alternative  Minimum Tax. The
proceeds  will be used to fund the 2000 and 2001  capital  projects to clean and
cement line previously unlined pipes and mains.

NOTE 4 - EARNINGS PER SHARE

Basic earnings per share (EPS) are computed on the basis of the weighted average
number of shares  outstanding.  Diluted EPS assumes the  conversion  of both the
Convertible  Preferred  Stock $7.00 Series and the  Convertible  Preferred Stock
$8.00 Series.

NOTE 5 - BUSINESS SEGMENT DATA

The  Company  has  identified  two  reportable  segments.  One is the  regulated
business  of  collecting,  treating  and  distributing  water  on a  retail  and
wholesale  basis to  residential,  commercial,  industrial  and fire  protection
customers  in parts of New Jersey and  Delaware.  It also  operates a  regulated
wastewater system in New Jersey. The Company is subject to regulations as to its
rates,  services and other matters by the States of New Jersey and Delaware with
respect  to  utility  service  within  these  States.  The other  segment is the
non-regulated  contract  services for the operation and maintenance of municipal
water and wastewater systems. On January 1, 1999 the Company began operating the
water and  wastewater  systems of the City of Perth  Amboy,  New Jersey  under a
service contract.  The accounting policies of the segments are the same as those
described  in the summary of  significant  accounting  policies in Note 1 to the
Consolidated  Financial  Statements.   Inter-segment  transactions  relating  to
operational  costs are  treated as pass  through  expenses.  Finance  charges on
inter-segment  loan  activities  are based on interest rates that are below what
would normally be charged by a third party lender.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS - THREE MONTHS ENDED SEPTEMBER 30, 1999

Operating  revenues for the quarter ended  September 30, 1999 rose 27.5% or $3.3
million  over the same period in 1998.  Better than half of the increase or $1.8
million is due to the contract  service revenues from the operations of the City
of Perth Amboy's water and wastewater systems.  Revenues from the May 1999 11.5%
increase in Middlesex  rates  accounted  for $1.3 million with  consumption  and
customer growth in Delaware contributing $0.2 million. Record water usage during
July and early  August in New  Jersey  was  completely  offset by the  statewide
drought  restrictions  imposed by the  Governor of New Jersey on August 6, 1999.
Generally, these restrictions were subsequently lifted on September 27, 1999. At
all times, Middlesex had adequate sources of water to supply its customers. This
fact, along with the Company's  objection to such a broad water  restriction was
communicated to State authorities.

Operating expenses increased for the quarter over last year's comparative period
by $2.7  million or 29.5%.  Perth Amboy  contract  expenses  were $1.6  million.
Together,  purchased  water  and  electric  costs  increased  by  $0.2  million.
Personnel  costs  rose $0.2  million.  The  improvements  to  Middlesex  primary
treatment  facility,  the Carl J. Olsen Water Treatment Plant (CJO Plant),  were
placed in  service  July  1999  causing  most of the $0.2  million  increase  in
depreciation  expense.  Other  Taxes  rose  $0.3  million  as a result of higher
revenue  related  taxes.  Federal  income  taxes  also  increased  $0.3  million
consistent with higher earnings for the period.

Other income fell $0.2 million due to lower  levels in the  Allowance  for Funds
Used During  Construction  (AFUDC) and investment income.  AFUDC was ceased once
the CJO Plant was placed in service. Expenditures for the CJO Plant expenditures
from  October  1998  through  1999  lowered  the amount of funds  available  for
investment.

RESULTS OF OPERATIONS - NINE MONTHS ENDED SEPTEMBER 30, 1999

Operating  revenues  for the nine  months  ended  September  30,  1999 rose $8.5
million or 26% compared to the first nine months of 1998.  The increase was made
up of $5.2 million from Perth Amboy contract revenues,  $2.2 million due to rate
increases in New Jersey,  $0.6 million from higher consumption in New Jersey and
$0.5 million from customer growth in Delaware.

Offsetting some of the higher revenues were increased operating expenses of $7.1
million.  The primary components of this 28.1% increase are Perth Amboy contract
expenses  of $4.8  million,  $0.4  million  for  purchased  water  and power and
personnel costs of $0.6 million.  Almost two thirds of the depreciation  expense
increase  of $0.3  million is due to the CJO Plant  additions.  Other Taxes rose
$0.7 million  mostly due to higher revenue  related taxes.  Federal income taxes
also increased $0.3 million consistent with higher earnings for the period.

A higher level of AFUDC  calculated  on CJO Plant capital  expenditures  for the
first nine  months of 1999 over 1998 added $0.7  million to other  income.  This
more than offset lower investment related earnings for the period.

Debt service related to the Series W and Y First Mortgage Bonds, issued in March
and November  1998,  respectively,  accounted  for the year to date  increase in
interest expense.

Basic  earnings per share  increased  $0.20 and diluted  earnings per share rose
$0.19.  The per share  dilution for the nine months ended  September 30, 1999 is
attributable  to  the  two  series  of  convertible  preferred  stock  currently
outstanding.

RESULTS OF OPERATIONS - TWELVE MONTHS ENDED SEPTEMBER 30, 1999

Operating revenues for the twelve months ended September 30, 1999 increased $9.0
million  or 21.2%.  Contributing  to this  increase  were Perth  Amboy  contract
revenues of $5.2 million,  rate increase  related  revenues of $2.7 million from
New Jersey  customers,  increased  consumption of $0.5 million and growth in our
Delaware service area amounted to $0.6 million.

Total operating expenses  increased $7.8 million or 23.5%.  Expenses incurred to
operate the Perth Amboy water and wastewater  systems  amounted to $4.9 million.
Other  factors that pushed  expenses up were salaries and wages of $0.9 million,
purchased  water of $0.3  million and  purchased  power  costs of $0.2  million.
Depreciation  expense  rose $0.3  million.  Other taxes  increased  $0.8 million
mostly due to higher revenue related taxes.

A higher  level of AFUDC  calculated  on CJO Plant  capital  expenditures  added
almost $1.0 million to other income and  investment  earnings  increased to push
other income up to just over $1.0 million.

Basic and  diluted  earnings  per share  grew at a lower  percentage  versus net
income due to the effect of the December  1998 common stock  offering of 515,000
shares.

CAPITAL RESOURCES

The  Company's  capital  program for 1999 is estimated  to be $24.1  million and
includes $15.0 million for the remaining expenditures for the upgrade of the CJO
Plant,  $2.0  million for the RENEW  Program,  which is our program to clean and
cement line  approximately  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.  The capital  program  also  includes  $3.3 million for water
system  additions and improvements for our Delaware systems and $3.8 million for
scheduled upgrades to our existing systems in New Jersey. The scheduled upgrades
consists of $1.6 million for mains, $0.7 million for service lines, $0.4 million
for meters, $0.3 million for hydrants and $0.8 million for various other items.

LIQUIDITY

Proceeds from the $23.0 million  Series W First  Mortgage Bonds and the December
1998.  $12.7  million  common stock  offering  have been used to finance the CJO
Plant  expenditures  in 1999.  Middlesex  issued $2.2 million of First  Mortgage
Bonds in November  1998  through the New Jersey  State  Revolving  Fund (SRF) to
cover the cost of the 1999 RENEW Program.  The capital  program in Delaware will
be financed through a combination of a capital  contribution  from Middlesex and
long-term  debt  financing  from either a financial  institution or the Company.
Other capital  expenditures will be financed through internally  generated funds
and sale of common  stock  through the  Dividend  Reinvestment  and Common Stock
Purchase Plan (DRP). Capital expenditures of $15.4 million have been incurred in
the nine  months  ended  September  30,  1999.  The  Company  may  also  utilize
short-term  borrowings through $28.0 million of available lines of credit it has
with three commercial banks for working capital purposes. At September 30, 1999,
there were $1.0 million of loans outstanding against the lines of credit.

ACCOUNTING STANDARDS

In June 1998, The Financial  Accounting  Standards  Board (FASB) issued SFAS No.
133,  "Accounting  for  Derivative  Instruments  and Hedging  Activities."  This
Statement   establishes   accounting  and  reporting  standards  for  derivative
instruments,   including  certain  derivative   instruments  embedded  in  other
contracts.   The  Company  is  currently  evaluating  the  requirements  of  the
accounting  standard,  which is required  to be adopted in the first  quarter of
2001.

YEAR 2000 READINESS

The Company, through its year 2000 (Y2K) Committee,  continues to advance in its
efforts to ensure that our ability to provide service will not be interrupted by
Y2K related problems.

Responses to our critical  vendor  questionnaire  have  reached  100%.  Critical
vendors include electric utilities, chemical companies, bulk water suppliers and
telecommunications   providers.   Each  vendor  has  indicated  their  level  of
readiness.  Middlesex  contingency plans have been formalized and were submitted
to the BPU in August 1999.  Contingency  plans for our Delaware water  utilities
have been  submitted to the Delaware  Public  Service  Commission.  The costs to
implement these plans are currently projected to be less than $0.1 million.

The Y2K Committee  has  completed  its  inventory of equipment  that may contain
embedded  chips.  Y2K  compliance  statements  have been received for all of the
manufactured  equipment  in question.  In each  instance  the  manufacturer  has
indicated that the equipment or components in use are not Y2K  sensitive.  Based
on the  information  received,  Y2K testing for the respective  equipment is not
being  considered.  The ability of our financial  system to recognize  post 1999
dates was tested and determined to be compliant.

Our customer  billing and  information  system has been tested and classified as
Y2k compliant.  All customers have received  notification of our plans to ensure
service as usual on January 1, 2000.

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,  objective,  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.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES OF MARKET RISK

The Company is subject to the risk of  fluctuating  interest rates in the normal
course of business.  Our policy is to manage  interest  rates through the use of
fixed  rate  long-term  debt  and,  to a lesser  extent,  short-term  debt.  The
Company's  interest rate risk related to existing fixed rate,  long-term debt is
not material due to the term of the majority of our First Mortgage Bonds,  which
have final maturity dates ranging from 2009 to 2038. Over the next twelve months
approximately  $0.1 million of the current  portion of three existing  long-term
debt  instruments  will mature.  Applying a  hypothetical  change in the rate of
interest  charged by 10% on those borrowings would not have a material effect on
earnings.
