MIDDLESEX WATER COMPANY

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 - Summary of Significant Accounting Policies

Organization - Middlesex Water Company (Middlesex or the Company) is the parent company and sole shareholder of Tidewater Utilities, Inc. (Tidewater), Tidewater Environmental Services, Inc. (TESI), Pinelands Water Company (Pinelands Water) and Pinelands Wastewater Company (Pinelands Wastewater) (collectively, Pinelands), Utility Service Affiliates, Inc. (USA), and Utility Service Affiliates (Perth Amboy) Inc. (USA-PA). On January 1, 2006, the Company's Bayview Water Company subsidiary was merged into Middlesex. Southern Shores Water Company, LLC (Southern Shores) and White Marsh Environmental Systems, Inc. (White Marsh) 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 significant intercompany accounts and transactions have been eliminated.

The consolidated notes within the 2005 Form 10-K are applicable to these financial statements and, in the opinion of the Company, the accompanying unaudited condensed consolidated financial statements contain all adjustments necessary (including normal recurring accruals) to present fairly the financial position as of March 31, 2006 and the results of operations for the three month periods ended March 31, 2006 and 2005, and cash flows for the three month periods ended March 31, 2006 and 2005. Information included in the Balance Sheet as of December 31, 2005, has been derived from the Company's audited financial statements for the year ended December 31, 2005.

Certain reclassifications have been made to the prior year financial statements to conform with the current period presentation.

Recent Accounting Pronouncements - In May 2005, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No.154, "Accounting Changes and Error Corrections" (SFAS 154), which requires retrospective application to prior periods' financial statements of voluntary changes in accounting principles unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS 154 makes a distinction between "retrospective application" of an accounting principle and the "restatement" of financial statements to reflect the correction of an error. SFAS 154 replaces Accounting Principles Bulletin (APB) No. 20, "Accounting Changes" (APB 20), and SFAS No. 3, Reporting Accounting Changes in Interim Financial Statements. APB 20 previously required that most voluntary changes in accounting principles be recognized by including the cumulative effect of changing to the new accounting principle in the net income of the period of the change. SFAS 154 requires that a change in depreciation, amortization or depletion method for long-lived non-financial assets be accounted for as a change in accounting estimate affected by a change in accounting principle, whereas APB 20 had required accounting for such a change as a change in accounting principle. SFAS 154 carries forward the guidance in APB 20 for reporting the correction of an error in previously issued financial statements and a change in accounting estimate as well as the requirement for justifying a change in accounting principle on the basis of a preference. This statement is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005 (January 1, 2006 for the Company).

In December 2004, the FASB issued SFAS No.123(R), "Share-Based Payment" (SFAS
123(R)), which replaces SFAS No. 123, "Accounting for Stock-Based Compensation" (SFAS 123), and supersedes APB Opinion No. 25, "Accounting for Stock Issued to Employees". SFAS 123(R) requires that the cost resulting from all share-based payment transactions be recognized in the financial statements. The Statement also establishes fair

5

value as the measurement objective in accounting for share-based payment arrangements and requires all entities to apply a fair-value-based measurement method in accounting for share-based payment transactions with employees, except for equity instruments held by employee share ownership plans. This statement was originally effective for quarters beginning after June 15, 2005, however on April 14, 2005, the Securities and Exchange Commission adopted a rule which makes the provisions of SFAS 123(R) effective for the first annual reporting period beginning after June 15, 2005 (January 1, 2006 for the Company). The Company previously recognized compensation expense at fair value for stock-based payment awards in accordance with SFAS 123 and the adoption of this standard did not have a material impact on the Company's financial position, results of operations, or cash flows.

In November 2005, the FASB issued FASB Staff Position (FSP) FAS115-1/124-1, "The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments," which addresses the determination as to when an investment is considered impaired, whether that impairment is other than temporary, and the measurement of an impairment loss. This FSP also includes accounting considerations subsequent to the recognition of another-than-temporary impairment and requires certain disclosures about unrealized losses that have not been recognized as other-than-temporary impairments. The guidance in this FSP amends FASB Statements No. 115, "Accounting for Certain Investments in Debt and Equity Securities," and No. 124, "Accounting for Certain Investments Held by Not-for-Profit Organizations," and APB Opinion No. 18, "The Equity Method of Accounting for Investments in Common Stock." The FSP was effective for accounting for reporting periods beginning after December 15, 2005 (January 1, 2006 for the Company). The adoption of this FSP had no impact on the Company's financial position, results of operations, or cash flows.

Rate Matters - On April 28, 2006, Tidewater filed for a $5.5 million, or 38.6%, base rate increase with the Delaware Public Service Commission (PSC). The requested increase is intended to recover increased costs of operations, maintenance and taxes, as well as capital investment of approximately $23.8 million since March 2005. We cannot predict whether the PSC will ultimately approve, deny, or reduce the amount of our request. Concurrent with the rate increase filing, Tidewater also submitted a request for a 15% interim rate increase subject to refund. Under PSC regulations, interim rates may go into effect 60 days after the initial request is submitted.

Effective April 13, 2006, Pinelands Water and Pinelands Wastewater received approval from the New Jersey Board of Public Utilities (BPU) for base rate increases of 7.02% and 0.98%, respectively. This increase represents a total base rate increase of approximately $0.1 million for Pinelands to help offset the increased costs associated with capital improvements, and the operation and maintenance of their systems.

In accordance with the tariff established for Southern Shores, an annual rate increase of 3% was implemented on January 1, 2006. Under the terms of a contract with Southern Shores Homeowners Association, the increase cannot exceed the lesser of the regional Consumer Price Index or 3%. The rates are set to expire on December 31, 2006, and the Company is currently negotiating a new agreement.

Stock Based Compensation - The Company recognizes compensation expense at fair value for its restricted stock awards in accordance with SFAS 123(R). As discussed in Note 1, SFAS 123(R) the adoption of this standard did not have a material impact on the Company's financial position, results of operations, or cash flows.

The Company maintains a Restricted Stock Plan, under which 56,067 shares of the Company's common stock are held in escrow by the Company as of March 31, 2006 for key employees. Such stock is subject to an agreement requiring forfeiture by the employee in the event of termination of employment within five years of

6

the award other than as a result of retirement, death, disability or change in control. The maximum number of shares authorized for grant under this plan is 240,000 shares. There were no grants, vesting or forfeitures of restricted stock during the three months ended March 31, 2006.

Compensation expense is determined by the market value of the stock on the date of the award and is being amortized over a five-year period. Compensation expense for the three months ended March 31, 2006 and 2005 was $0.1 million. Total unearned compensation related to restricted stock was $0.6 million at March 31, 2006.

Note 2 - Capitalization

Common Stock -During the three months ended March 31, 2006, there were 18,739 common shares (approximately $0.4 million) issued under the Company's Dividend Reinvestment and Common Stock Purchase Plan.

Long-term Debt - Middlesex filed an application with the BPU seeking approval to issue up to $4.0 million of first mortgage bonds through the New Jersey Environmental Infrastructure Trust under the New Jersey State Revolving Fund (SRF) program. If approved by the BPU, the Company expects to close on the bonds in November 2006.

On April 25, 2006, Tidewater received approval from the PSC to borrow up to $1.0 million under the Delaware SRF program. The Delaware SRF program allows, but does not obligate, Tidewater to draw against a General Obligation Note for a specific project over a two-year period ending in April 2008. The interest rate is set on the loan closing date and is based on 62.5% of the interest rate for a 10+ year high quality corporate bond. The Company expects to close on the loan during May 2006.

Note 3 - Earnings Per Share

Note 4 - 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. This segment also includes the operations of 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 services within these States. The other segment primarily includes non-regulated contract services for the operation and maintenance of municipal and private water and wastewater systems in New Jersey and Delaware. The accounting policies of the segments are the same as those described in the summary of significant accounting policies in the Consolidated Notes to the Financial Statements in the Company's Annual Report for the period ended December 31, 2005 filed on Form 10-K. 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. These inter-segment transactions are eliminated in the Company's consolidated financial statements.

Note 5 - Short-term Borrowings

As of March 31, 2006, the Company has established lines of credit aggregating $40.0 million. At March 31, 2006, the outstanding borrowings under these credit lines were $7.2 million at a weighted average interest rate of 5.24%. As of that date, the Company had borrowing capacity of $32.8 million under its credit lines.

The weighted average daily amounts of borrowings outstanding under the Company's credit lines and the weighted average interest rates on those amounts were $5.9 million and $10.4 million at 5.59% and 3.85% for the three months ended March 31, 2006 and 2005, respectively.

Note 6 - Commitments and Contingent Liabilities

Guarantees - USA-PA operates the City of Perth Amboy's (Perth Amboy) water and wastewater systems under a service contract agreement through June 30, 2018. The agreement was 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 receives a fixed fee and a variable fee based on increased system billing. Scheduled fixed fee payments for 2006 are $7.6 million. The fixed fees will increase over the term of the contract to $10.2 million.

In connection with the agreement, Perth Amboy, through the Middlesex County Improvement Authority, issued approximately $68.0 million in three series of bonds. Middlesex guaranteed one of those series of bonds, designated the Series C Serial Bonds, in the principal amount of approximately $26.3 million. Perth Amboy guaranteed the two other series of bonds. The Series C Serial Bonds have various maturity dates with the final maturity date on September 1, 2015. As of March 31, 2006, approximately $23.9 million of the Series C Serial Bonds remained outstanding.

We are obligated to perform under the guarantee in the event notice is received from the Series C Serial Bonds trustee of an impending debt service deficiency. If Middlesex funds any debt service obligations as guarantor, there is a provision in the agreement that requires Perth Amboy to reimburse us. There are other provisions in the agreement that we believe make it unlikely that we will be required to perform under the guarantee, such as scheduled annual rate increases for water and wastewater services as well as rate increases due to unforeseen circumstances. In the event revenues from customers could not satisfy the reimbursement requirements, Perth Amboy has Ad Valorem taxing powers, which could be used to raise the needed amount.

Water Supply - Middlesex has an agreement with the New Jersey Water Supply Authority (NJWSA) for the purchase of untreated water through November 30, 2023, which provides for an average purchase of 27 million gallons per day (mgd). Pricing is set annually by the NJWSA through a public rate making process. The agreement has provisions for additional pricing in the event Middlesex overdrafts or exceeds certain monthly and annual thresholds.

Middlesex also has an agreement with a non-affiliated regulated water utility for the purchase of treated water. This agreement, which expires February 27, 2011, provides for the minimum purchase of 3 mgd of treated water with provisions for additional purchases.

Purchased water costs are shown below:

Construction - The Company expects to spend approximately $44.5 million on its construction program in 2006.

Litigation - A lawsuit was filed in 1998 against the Company by an electric utility for damages involving the break of both a Company water line and an underground electric power cable containing both electric lines and petroleum based insulating fluid. The electric utility also asserted claims against the Company. The lawsuit was settled in 2003, and by agreement, the electric utility's counterclaim for approximately $1.1 million in damages was submitted to binding arbitration, in which the agreed maximum exposure of the Company is $0.3 million, for which the Company has accrued a liability. While we are unable to predict the outcome of the arbitration, we believe that we have substantial defenses.

During 2005, the Office of State Fire Marshal in Delaware issued a Notice of Violation (NOV) to Tidewater regarding a plan of correction to provide fire protection services to one of Tidewater's community water systems, based upon a recent interpretation by the Fire Marshal of regulations that have been effective since 1989. Tidewater has appealed this NOV in the Superior Court of the State of Delaware on the grounds that the water system was grandfathered under the 1989 regulations and that due process had not been served in the application of the recent interpretation. It is the Company's position that Tidewater is not required to provide fire protection service to that water system. If Tidewater is not successful in its appeal, it would be required to install a fire protection system in this community at an estimated capital cost of $0.9 million to $1.6 million. If the Company is unsuccessful in its appeal, we cannot predict what further actions, if any, or the costs or timing thereof, may be taken by the Fire Marshal regarding over 60 of Tidewater's other community water systems. However, such amounts could be material. The Company believes that any capital investments resulting from an unfavorable outcome would be a component of Tidewater's rate base and therefore, included in future rates. While we are unable to predict the outcome of our appeal, we believe that we have substantial defenses.

The Company is a defendant in various lawsuits in the normal course of business. We believe the resolution of pending claims and legal proceedings will not have a material adverse effect on the Company's consolidated financial statements.

Change in Control Agreements - The Company has Change in Control Agreements with certain of its Officers that provide compensation and benefits in the event of termination of employment in connection with a change in control of the Company.

Note 7 - Employee Retirement Benefit Plans

Pension - The Company has a noncontributory defined benefit pension plan, which covers all employees with more than 1,000 hours of service. The Company expects to make cash contributions of $1.2 million during the current year. These contributions are expected to be made during the second quarter of 2006. In addition, the Company maintains an unfunded supplemental pension plan for its executives.

10

Postretirement Benefits Other Than Pensions - The Company maintains a postretirement benefit plan other than pensions for substantially all of its retired employees. Coverage includes healthcare and life insurance. Retiree contributions are dependent on credited years of service. The Company expects to make total cash contributions of $1.0 million during the current year. These contributions are expected to be made each quarter during 2006.

The following table sets forth information relating to the Company's periodic costs for its retirement plans.

Overview

The Company has operated as a water utility in New Jersey since 1897, and in Delaware, through our wholly-owned subsidiary, Tidewater, since 1992. We are in the business of collecting, treating, distributing and selling water for residential, irrigation, commercial, municipal, industrial and fire protection purposes. We also operate a New Jersey municipal water and wastewater system under contract and provide wastewater services in New Jersey and Delaware through our subsidiaries. We are regulated as to rates charged to customers for water and wastewater services in New Jersey and Delaware, as to the quality of water service we provide and as to certain other matters. Our USA, USA-PA and White Marsh subsidiaries are not regulated utilities.

Our New Jersey water utility system (the Middlesex System) provides water services to approximately 58,500 retail customers, primarily in central New Jersey. The Middlesex System also provides water service under contract to municipalities in central New Jersey with a total population of approximately 267,000. Through our subsidiary, USA-PA, we operate the water supply system and wastewater collection system for the City of Perth Amboy, New Jersey. Pinelands Water and Pinelands Wastewater provide water and wastewater services to residents in Southampton Township, New Jersey.

Tidewater and Southern Shores provide water services to approximately 28,700 retail customers in New Castle, Kent, and Sussex Counties, Delaware. Our TESI subsidiary provides service to approximately 30 residential retail customers. White Marsh serves 4,000 residents under unregulated operating contracts with various owners of small water and wastewater systems in Kent and Sussex Counties.

Our USA subsidiary provides customers within the Middlesex System a service line maintenance program called LineCareSM.

The majority of our revenue is generated from retail and contract water services to customers in our service areas. We record water service revenue as such service is rendered and include estimates for amounts unbilled at the end of the period for services provided after the last billing cycle. Fixed service charges are billed in advance by our subsidiary, Tidewater, and are recognized in revenue as the service is provided.

Our ability to increase operating income and net income is based significantly on four factors: weather, adequate and timely rate relief, effective cost management, and customer growth. These factors are evident in the discussions below which compare our results of operations with prior periods.

Recent Developments

Rate Increases

On April 28, 2006, Tidewater filed for a $5.5 million, or 38.6%, base rate increase with the Delaware Public Service Commission (PSC) on April 28, 2006. The requested increase is intended to recover increased costs of operations, maintenance and taxes, as well as capital investment of approximately $23.8 million since March 2005. We cannot predict whether the PSC will ultimately approve, deny, or reduce the amount of our request. Concurrent with the rate increase filing, Tidewater also submitted a request for a 15% interim rate increase subject to refund. Under PSC regulations, interim rates may go into effect 60 days after the initial request is submitted.

Effective April 13, 2006, Pinelands Water and Pinelands Wastewater received approval from the BPU for base rate increases of 7.02% and 0.98%, respectively. This increase represents a total base rate increase of approximately $0.1 million for Pinelands to help offset the increased costs associated with capital improvements, and the operation and maintenance of their systems.

In accordance with the tariff established for Southern Shores, an annual rate increase of 3% was implemented on January 1, 2006. Under the terms of a contract with the Southern Shores Homeowners Association, the increase cannot exceed the lesser of the regional Consumer Price Index or 3%. The rates are set to expire on December 31, 2006, and the Company is currently negotiating a new agreement.

Merger of Bayview Water Company into Middlesex Water Company

In December 2005, the BPU approved a merger of Bayview into the Middlesex system effective January 1, 2006. As part of the BPU's stipulation approving the merger, the water service rates for the customers of Bayview are to remain at their current levels until the water service rates for Middlesex customers exceed the current Bayview rates.

Operating Results by Segment

The Company has two operating segments, Regulated and Non-Regulated. Our Regulated segment contributed 88% of total revenues and 92% of net income for the three months ended March 31, 2006 and 2005. The discussion of the Company's results of operations is on a consolidated basis, and includes significant factors by subsidiary. The segments in the tables included below are comprised of the following companies: Regulated- Middlesex, Tidewater, Pinelands, Southern Shores, and TESI; Non-Regulated- USA, USA-PA, and White Marsh.

Operating revenues for the three months ended March 31, 2006 increased $1.5 million or 8.9% from the same period in 2005. Water sales increased by $1.0 million in our New Jersey systems, which was primarily a result of base rate increases. Revenues rose in our Delaware systems by $0.3 million. Customer growth in Delaware provided additional water consumption sales, facility charges and connection fees totaling $0.2 million. Base rate increases accounted for $0.1 million of the increase. New unregulated wastewater contracts in Delaware provided $0.1 million of additional revenues. USA's LineCareSM maintenance program contributed an additional $0.1 million for new contracts sold since the same period in 2005. Revenues for all of our other operations were consistent with the same period in 2005.

While we anticipate continued organic customer and consumption growth in our Delaware systems, such growth and increased consumption cannot be guaranteed. Revenues from our water systems are highly dependent on the effects of weather, which may adversely impact future consumption despite customer growth. Appreciable organic customer and consumption growth is less likely in our New Jersey systems due to the extent to which our service territory is developed.

Operation and maintenance expenses increased $0.4 million or 4.5%. Water production and treatment costs for the Middlesex system increased $0.2 million. This increase was offset by reduced payroll and benefits costs of $0.2 million in New Jersey. In Delaware, insurance, legal fees, and additional employees and related benefit expenses increased by $0.2 million. The costs of providing services for new unregulated wastewater contracts increased by $0.1 million. Costs for all of our other operations increased by $0.1 million.

We anticipate increases in electric generation costs beginning May 2006 in Delaware due to deregulation of electricity. We expect our pension and postretirement costs to increase in 2006. Payroll and related employee benefit costs (excluding pension and postretirement expenses previously discussed) are also expected to be higher in 2006.

Depreciation expense increased $0.1 million or 7.8%, primarily as a result of a higher level of utility plant in service.

15

Other taxes increased by $0.1 million, reflecting higher taxes on taxable gross revenues.

Other income decreased $0.1 million, primarily due to reduced AFUDC as a result of the completion of a new $9.3 million raw water pipeline in New Jersey in April 2005.

Interest expense increased by $0.1 million, primarily due to higher average long-term borrowings as compared to the prior year period.

Higher income taxes of $0.1 million over the prior year are attributable to improved operating results for 2006 as compared to 2005.

Net income increased by 31.3% to $1.8 million, and basic and diluted earnings per share increased from $0.12 to $0.15.

Liquidity and Capital Resources

Cash flows from operations are largely dependent on three factors: the impact of weather on water sales, adequate and timely rate increases, and customer growth. The effect of those factors on net income is discussed in results of operations. For the three months ended March 31, 2006, cash flows from operating activities were $4.7 million, which was $1.7 million higher than the prior year. This increase was attributable to the timing of collection of customer accounts and payments for taxes. These increases were partially offset by the timing of payments to vendors and payments of interest. The $4.7 million of net cash flow from operations allowed us to fund all of our utility plant expenditures internally for the period.

The Company's capital program for 2006 is estimated to be $44.5 million and includes $20.2 million for additions and improvements to our Delaware water systems, including the construction of several storage tanks and the creation of new wells and interconnections. We expect to spend approximately $13.9 million for system additions and acquisitions for our Delaware wastewater systems. We expect to spend $3.3 million for the RENEW program, to clean and cement line approximately nine miles of unlined mains in the Middlesex system. There remains a total of approximately 120 miles of unlined mains in the 730-mile Middlesex system. The capital program also includes $7.1 million for scheduled upgrades to facilities in New Jersey. These upgrades consist of $1.4 million for improvements to existing plant, $1.0 million for mains, $0.8 million for service lines, $0.4 million for meters, $0.3 million for hydrants, and $3.2 million for other infrastructure needs.

To fund our capital program in 2006, we will utilize internally generated funds and funds available under existing New Jersey Environmental Infrastructure Trust
(NJEIT) loans (currently, $4.1 million) and Delaware State Revolving Fund (SRF)
loans (currently, $2.9 million), which provide low cost financing for projects that meet certain water quality and system improvement benchmarks. We will also utilize short-term borrowings through $40.0 million of available lines of credit with several financial institutions. As of March 31, 2006, $7.2 million was outstanding against the lines of credit.

Middlesex filed an application with the BPU seeking approval to issue up to $4.0 million of first mortgage bonds through the NJEIT. If approved by the BPU, the Company expects to close on the bonds in November 2006.

On April 25, 2006, Tidewater received approval from the PSC to borrow up to $1.0 million under the Delaware SRF program. The Delaware SRF program allows, but does not obligate, Tidewater to draw against a General Obligation Note for a specific project over a two-year period ending in April 2008. The interest rate is set on the

16

loan closing date and is based on 62.5% of the interest rate for a 10+ year high quality corporate bond. The Company expects to close on the loan during May 2006.

The Company periodically issues shares of common stock in connection with its dividend reinvestment and stock purchase plan. From time to time, the Company may issue additional equity to reduce short-term indebtedness, align its capital structure with utility commission guidelines, and for other general corporate purposes.

Going forward into 2007 through 2008, we currently project that we will be required to expend approximately $112.2 million for capital projects. To the extent possible and because of the favorable interest rates available to regulated water utilities, we will finance our capital expenditures under SRF loan programs. We also expect to use internally generated funds and proceeds from the sale of common stock through the Dividend Reinvestment and Common Stock Purchase Plan. We also expect to sell shares of our common stock through a public offering in late 2006 or early 2007.

In addition to the effect of weather conditions on revenues, increases in certain operating costs will impact our liquidity and capital resources. As described in our overview section, we have recently received rate relief for Middlesex and Pinelands. Changes in operating costs and timing of capital projects will have an impact on revenues, earnings, and cash flows and will also impact the timing of filings for future rate increases.

Recent Accounting Pronouncements - See Note 1 of the Notes to Unaudited Condensed Consolidated Financial Statements for a discussion of recent accounting pronouncements.

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 capital program is partially financed with 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 Amortizing Secured Notes and First Mortgage Bonds, which have maturity dates ranging from 2009 to 2038. Over the next twelve months, approximately $2.0 million of the current portion of fifteen existing long-term debt instruments will mature. Applying a hypothetical change in the rate of interest of 10% on those borrowings would not have a material effect on earnings.

Item 4. Controls and Procedures

As required by Rule 13a-15 under the Exchange Act, an evaluation of the effectiveness of the design and operation of the Company's disclosure controls and procedures was conducted by the Company's Chief Executive Officer along with the Company's Chief Financial Officer. Based upon that evaluation, the Company's Chief Executive Officer and the Company's Chief Financial Officer concluded that the Company's disclosure controls and procedures are effective as of the end of the period covered by this Report. There have been no significant changes in the Company's internal controls or in other factors, which could significantly affect internal controls during the quarter ended March 31, 2006.

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in Company reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in Company reports filed under the

17

Exchange Act is accumulated and communicated to management, including the Company's Chief Executive Officer and Chief Financial Officer as appropriate, to allow timely decisions regarding disclosure.

WATER SERVICE AGREEMENT

BETWEEN

MIDDLESEX WATER COMPANY

AND

ELIZABETHTOWN WATER COMPANY

THIS AGREEMENT made this 28th day of February, 2006,

BETWEEN

ELIZABETHTOWN WATER COMPANY, a public utility and corporation organized under the laws of the State of New Jersey, with its principal office 131 Woodcrest Road, Cherry Hill, County of Camden, State of New Jersey,

hereinafter referred to as "ELIZABETHTOWN,"

AND

MIDDLESEX WATER COMPANY, a public utility and corporation organized under the laws of the State of New Jersey, with its office 1500 Ronson Road, Iselin, Woodbridge Township, County of Middlesex, State of New Jersey,

hereinafter referred to as "MIDDLESEX,"

WHEREAS, MIDDLESEX desires to obtain an additional supply of potable water for its use and for that of its customers; and

WHEREAS, ELIZABETHTOWN has a Rate Schedule No. 8, "Service to Other Systems Under Contract," filed under authority of the New Jersey Board of Public Utilities, and MIDDLESEX desires to obtain a supply of water under that rate schedule and subject to its provisions, as may be amended and supplemented under approval of the New Jersey Board of Public Utilities; and

WHEREAS, ELIZABETHTOWN and MIDDLESEX presently have an Agreement for water supply dated April 28, 1995 as extended by agreement dated December 21, 2005, and the parties desire to have this Agreement supersede the said extended Agreement;

NOW, THEREFORE, in consideration of the mutual promises and covenants herein, it is agreed by the parties hereto as follows:

1. Effective upon the execution of this Agreement, ELIZABETHTOWN agrees to sell, deliver and transport to MIDDLESEX 3,000,000 gallons of potable water per day and MIDDLESEX agrees to accept and pay for a minimum daily quantity of water in the amount of 3,000,000 gallons per day (MGD) from the water sources and supplies of ELJZABETHTOWN at the rate set forth in Rate Schedule No. 8, "Service to Other Systems Under Contract," and subject to its provisions as they may be amended and supplemented under approval of the New Jersey Board of Public Utilities.


If available in ELIZABETHTOWN's reasonable determination, ELIZABETHTOWN will allow MIDDLESEX to take, on an as needed basis, as much water as ELIZABETHTOWN is capable of providing without affecting the minimum daily quantity requirement.

2. The initial obligation of both parties to perform in accordance with the terms and conditions of this contract shall begin upon the date of signing this contract and expire five (5) years from said date, provided that this agreement shall renew for additional five (5) year periods unless either party gives notice to the other no later than one (1) year before the end of the then current term.

3. All water supplied to MIDDLESEX by ELIZABETHTOWN shall be metered by meters owned and maintained by ELIZABETHTOWN, at the existing meter station commonly known as Tingley Lane, and such other locations as may be agreed upon by the parties.

4. Where the words "daily" is used in this Agreement, it shall refer to the 24-hour period between daily meter readings. Meter readings shall be taken daily when feasible, and if not, the meter readings shall be averaged over a weekly or monthly period to arrive at an average daily quantity of water delivered.

5. In the event that the total daily quantity of water delivered by ELIZABETHTOWN exceeds 3,000,000 gallons per day, such excess quantity of water shall be paid for at the rate set forth in Rate Schedule No. 8, "Service to Other Systems Under Contract."

6. The parties hereby agree that the agreed upon minimum daily quantity of water shall not be decreased during the term of this Agreement.

7. All water supplied and delivered to MIDDLESEX pursuant to this Agreement will comply with all primary Federal and State Safe Drinking Water Act requirements. ELIZABETHTOWN will provide notice to MIDDLESEX of any violation in the water supplied to MIDDLESEX of the Maximum Contamination Levels, as required in the Federal and State Safe Drinking Water Acts. ELIZABETHTOWN will provide to MIDDLESEX a copy of New Jersey Department of Environmental Protection Safe Drinking Water Act Water Quality Reports for the ELIZABETHTOWN supply.

8. ELIZABETHTOWN agrees to provide a continuous, regular and uninterrupted transmission of water, subject to the terms of this Agreement, and subject further to interruptions by reasons of an Act of God, strike, State or Municipal interference or other causes beyond its control. In such event, ELIZABETHTOWN shall not be liable to MIDDLESEX for damages by reason of interruptions in supply of water to MIDDLESEX or its customers as a result of such interruptions unless the same arises out of any gross negligence, breach of warranty or other breach of duty by ELIZABETHTOWN.

ELIZABETHTOWN agrees to excuse payment obligations of MIDDLESEX if, by reason of an Act of God, strike, State or Municipal interference or other causes outside either party's control, there is a disruption of water being transmitted to MIDDLESEX by ELIZABETHTOWN.

9. MIDDLESEX shall completely indemnify, protect and save harmless ELIZABETHTOWN from any and all costs, expenses, including legal fees, liabilities, losses, claims, suits and proceedings of whatsoever nature arising out of any negligence, breach of warranty or other breach of duty by MIDDLESEX in relation to the obligations contained herein.

10. ELIZABETHTOWN shall completely indemnify, protect and save harmless


MIDDLESEX from any and all costs, expenses, including legal fees, liabilities, losses, claims, suits and proceedings of whatsoever nature arising out of any negligence, breach of warranty or other breach of duty by ELIZABETHTOWN in relation to the obligations contained herein.

11. ELIZABETHTOWN and MIDDLESEX hereby release the other from all claims, liability and performance under the aforesaid contract dated April 28, 1995 as extended by agreement on December 21, 2005, unless such claims or liability shall have accrued by the effective date of this Agreement.

12. This Agreement shall be governed by and interpreted in accordance with the laws of the State of New Jersey.

13. This Agreement shall be filed with the Board of Public Utilities of the State of New Jersey and approved by the Department of Environmental Protection of the State of New Jersey, as required.

IN WITNESS WHEREOF, the ELIZABETHTOWN WATER COMPANY has caused these presents to be signed by its Vice President and its corporate seal to be affixed hereto and attested by its Secretary, and the MIDDLESEX WATER COMPANY, in the County of Middlesex, has caused these presents to be signed by its President and its corporate seal to be affixed hereto and attested by its Secretary, the day and year first written above.

Exhibit 10.1

AGREEMENT

FOR A SUPPLY OF WATER

BY

MIDDLESEX WATER COMPANY

TO THE

BOROUGH OF HIGHLAND PARK


Dated as of January 1, 2006



This Agreement (hereinafter referred to as the "Agreement") made as of this 1st day of January 2006 between:

MIDDLESEX WATER COMPANY, a public utility and corporation organized under the laws of the State of New Jersey, with offices at 1500 Ronson Road, Iselin, New Jersey (hereinafter referred to as "Middlesex"),

and the

BOROUGH OF HIGHLAND PARK, a municipal corporation of the State of New Jersey (hereinafter referred to as "Highland Park").

W I T N E S S E T H:

WHEREAS, Middlesex owns and operates a public water supply system; and

WHEREAS, Highland Park has requested that Middlesex provide it with additional supplies of water for private and public use; and

WHEREAS, the parties intend that their Agreement for a Supply of Water, dated as of October 24, 1995, as amended, is to be superseded by this new Agreement;

Now therefore, in consideration of the premises and of the mutual covenants herein contained, the parties agree that:

2

1. Supply of Water.

Middlesex agrees to supply Highland Park with water upon the terms and conditions set forth herein.

2. Term.

This Agreement shall be binding upon execution by both parties. Service under this Agreement shall begin on or about January 1, 2006, and service under this Agreement shall terminate on December 31, 2016. However, the terms of the Agreement shall remain in effect after December 31, 2016 unless written notice of intention to terminate the Agreement is given by either party at least thirty
(30) days prior to the end of such period. In the event that such notice has not been given, the Agreement shall remain in effect until the earlier of (a) renewal or modification of the Agreement by consent of both parties, or (b) a date no less than ninety (90) days after the date that either party provides written notification of termination.

3. Rate.

Highland Park shall pay for water delivered pursuant hereto at the rate of $1,476.72 per million gallons according to Rate Schedule No. 5 or as said rate may be changed from time to time with the approval of the Board of Public Utilities of the State of New Jersey, or its successor agency, as required by law (hereinafter referred to as the "Contract Rate").

3

4. Meter Stations/Delivery System.

Water to be supplied by Middlesex hereunder shall be delivered to Highland Park through existing interconnections in Suttons Lane in Edison adjacent to the railroad right of way, at Middlesex's Treatment Plant in Edison, and through such other points of delivery as may be agreed to from time to time by the parties (hereinafter referred to as the "Meter Stations"). The parties agree that Middlesex may install one or more additional interconnections on a large diameter transmission main (anticipated to be 36 or 42 inches in diameter) planned for future construction by Middlesex and extending from Middlesex's Treatment Plant in Edison, through the Borough of Highland Park, to a transmission main or other facilities of Middlesex. Any additional interconnections with the Borough of Highland Park would be installed by mutual agreement. The general route for the Transmission Main is shown on Exhibit A. (Said transmission main is hereinafter referred to as the "SRB Transmission Main" or the "Transmission Main".) The SRB Transmission Main may be constructed in phases.

The parties agree that Middlesex may proceed when it deems necessary with the construction of the SRB Transmission Main. The construction of the SRB Transmission Main and any service connections (and meter chambers) related to the SRB Transmission Main shall be at the sole cost of Middlesex. Highland Park agrees to cooperate and act in good faith in connection therewith and in

4

providing and obtaining necessary or desirable governmental approvals, authorizations, rights of way and other actions. Highland Park agrees to grant to Middlesex or to acquire for Middlesex, by purchase, condemnation, exchange or otherwise, to the extent legally authorized, all lands, and/or easements in Highland Park as are necessary or convenient for Middlesex's construction and use of the SRB Transmission Main, and for any other mains, pipelines and appurtenances necessary or convenient for water service to Highland Park with all costs borne by Middlesex. Middlesex agrees to comply with reasonable requirements of Highland Park for pavement and property restoration.

5. Meters, Services and Other Appurtenances.

Middlesex shall furnish, install and maintain at its own cost such service connections and meters as agreed upon by both parties for connection to Highland Park's water distribution system. The meters and service pipes shall remain the property of Middlesex. Highland Park shall furnish, install and maintain at its own cost all other piping, fittings, valves, meter pits or vaults and appurtenances necessary to take water from Middlesex.

6. Exclusive Supplier.

The parties agree that during the term of this Agreement, Middlesex shall be Highland Park's sole supplier of water. Except as provided in this paragraph, Highland Park shall not purchase water from any other supplier in the normal course of business. Highland Park shall have the right to purchase water from

5

other sources in the event of an emergency or during any periods of time that Middlesex is unable to supply water as provided in this Agreement.

7. Minimum Payment Obligation.

Highland Park shall be obligated to pay for the Daily Minimum quantity of water. "Daily Minimum" shall mean either (a) one million two hundred thousand (1.2 mgd) gallons of water a day, or (b) such greater amount as may be established under paragraph 8 of this Agreement.

All water taken in any 24-hour period in excess of the Daily Minimum shall be paid for at the Contract Rate.

8. Increase in Minimum Payment Obligation.

The total daily quantity of water taken by Highland Park at the Meter Stations may exceed the Daily Minimum by up to 100% on a 24-hour basis without affecting the minimum payment obligation.

The quantity of water supplied in the peak hour multiplied by 24 may exceed the Daily Minimum by 200% without affecting the minimum payment obligation.

If either the quantity of water taken in a 24-hour period shall exceed the Daily Minimum by more than 100% or if the maximum hourly flow multiplied by 24 shall exceed the Daily Minimum by more than 200%, the Daily Minimum will be increased to the greater of: (a) one-half of the daily quantity of water supplied in the 24-hour period; or (b) one-third of the quantity supplied in the peak hour

6

multiplied by 24. (For example, an existing Daily Minimum of 1.2 million gallons per day ("mgd") will be increased if the quantity of water taken in any 24-hour period exceeds 2.4 mgd, or if the quantity of water taken in any peak hour multiplied by 24 exceeds 3.6 mgd.)

In no instance, and under no conditions, shall the daily quantity of water supplied and purchased under this Agreement exceed 4.0 million gallons, nor shall the maximum hourly flow multiplied by 24 exceed 5.0 million gallons per day.

Any increased Daily Minimum payment obligation shall continue in effect for 12 months unless increased again by an overrun. After this 12-month period with the higher Daily Minimum in effect, the Daily Minimum shall revert to the next lower minimum incurred during the four months preceding the end of such 12-month period and that amount shall continue as the Daily Minimum for 12 months unless increased again by an overrun.

9. Combined Charge.

The Daily Minimum payment obligation shall be determined on the basis of the combined total daily quantity of water supplied through all the Meter Stations.

10. Definitions.

Where the words "daily" or "24-hours" are used in this contract, they shall refer to the 24-hour period between the daily meter readings.

7

11. Exceptions for Emergencies.

The Daily Minimum payment obligation shall not be affected in the event that the amount of water supplied to Highland Park exceeds the daily or hourly limitations established herein for not more than 24 hours in case of fire or main break emergencies and for not more than five days in the case of other catastrophes requiring an emergency supply of water, provided Middlesex is promptly notified that any such emergency exists.

12. Meter Readings.

Middlesex will read the meters daily for all water supplied to Highland Park at each connection then in operation.

13. Excused Performance.

Middlesex agrees to provide a continuous, regular and uninterrupted supply of water, subject to interruptions by reasons of acts of God, accident, strike, legal process, State or municipal interference or other cause beyond its control, but shall not be liable for damages to Highland Park by reasons of inadequate pressure or volume or failure to provide water for any cause whatever.

14. Indemnification/Limitation of Liability.

Highland Park shall completely indemnify, protect and save harmless Middlesex from any and all costs, expenses, liability, losses, claims, suits and proceedings of any nature whatsoever arising out of the water service by Highland Park. However, as to claims involving water quality, the within Article is intended

8

not to apply to water until after it is delivered to Highland Park's system,
i.e. after water is supplied through the Meter Stations referred to in Article 4.

Middlesex shall completely indemnify, protect and save harmless Highland Park from all costs, expenses, liability, losses, claims, suits and proceedings of any nature whatsoever arising out of any negligence of Middlesex.

Notwithstanding anything herein to the contrary, Middlesex's aggregate liability to Highland Park arising out of or in connection with this Agreement shall not exceed an amount equal to one year's gross revenues required to be paid by Highland Park to Middlesex based upon the Daily Minimum in effect at the time of the occurrence giving rise to the liability, and Highland Park hereby releases Middlesex from any liability in excess thereof. This paragraph is not intended to limit Middlesex's liability to third parties.

15. Regulatory Approvals.

If required by law, this Agreement shall be filed with and subject to approval by the Board of Public Utilities of the State of New Jersey and the Department of Environmental Protection of the State of New Jersey.

9

IN WITNESS WHEREOF, the parties have caused this Agreement to be duly executed as of the day and year first written above.

WHEREAS, Middlesex owns and operates a public water supply system; and

WHEREAS, Rahway has requested that Middlesex provide it with a supply of water for private and public use; and

WHEREAS, this Agreement is designed to set for the terms and conditions between the parties relating to a supply of water.

Now therefore, in consideration of the premises and of the mutual covenants herein contained, the parties agree that:

1. Supply of Water.

Middlesex agrees to supply Rahway with water, and Rahway agrees to accept such water upon the terms and conditions set forth herein.

2. Term.

The term of this Agreement shall be ten (10) years from the date hereof. Except as otherwise provided herein, or as the parties may mutually agree upon, service shall terminate on a date that is ten (10) years following the date hereof.

The terms of the Agreement shall remain in effect after the termination date and any periods of renewal of the Agreement, unless written notice of intention to terminate the Agreement is given by either party at least three hundred sixty-five (365) days prior to the end of any such period. In the event that such notice has not been given, the Agreement shall remain in effect until the earlier of (a) renewal or modification of the Agreement by consent of both parties, or (b) a date no less than three hundred sixty-five (365) days after the date that either party provides written notification of termination.

-2-

3. Rates.

Rahway shall pay Middlesex at a rate which is the sum of (a) the rate for Service Under Contract pursuant to Rate Schedule No. 5 of Middlesex's tariff, currently at the rate of $1,476.72 per million gallons (Exhibit A attached hereto), and (b) the rate for Transmission Service pursuant to Rate Schedule No. 8 of Middlesex's tariff, currently at the rate of $50.00 per million gallons (Exhibit B attached hereto); or as applicable rates and tariffs may be established and/or changed from time to time with the approval of the New Jersey Board of Public Utilities ("BPU") as required by law. (Such rate is hereinafter referred to as the "Contract Rate.") Rahway shall pay Middlesex at the said Contract Rate for the greater of the Daily Minimum quantity of water (as defined below in paragraph 7) or for all water delivered to Meter Stations (as defined below in paragraph 5 (Meter Stations/Points of Delivery) up to and including the Allowable Excess as determined under paragraph 8 (a). Rahway shall pay Middlesex the applicable Peaking Charges, set forth in paragraph 8, for all water in excess of the Allowable Excess, subject to the provisions of paragraph 9 hereof.

4. Delivery System.

Water to be supplied by Middlesex hereunder shall be delivered to Rahway through Middlesex's water transmission system and all existing interconnections located on such transmission system as existed at the date of this Agreement and such other interconnections as may be reasonably agreed upon from time to time.

5. Meter Stations/Points of Delivery.

The parties understand and agree that delivery shall be made through such points of delivery into the Rahway system as may be reasonably agreed upon from time to time by the parties (hereinafter referred to as "Meter Stations"). Water so supplied shall be metered at the Meter Stations.

6. Meters, Services and Other Appurtenances.

Middlesex shall furnish, install and maintain at its own cost such service connections and meters as it shall deem necessary for connection to the Meter Stations. The meters and service pipes shall remain the property of Middlesex. Middlesex shall maintain and verify the accuracy of said meters at least annually, and Rahway, at its sole cost, shall have the right to test the meters at the Meter Stations by a certified meter

-3-

technician at any reasonable time upon written notice to Middlesex. Rahway shall provide for furnishing, installing and maintaining at its own cost all other piping, fittings, valves, meter pits or vaults and appurtenances, including pressure reducing stations, necessary to take water from Middlesex.

7. Minimum Payment Obligation.

(a) Rahway shall be obligated to pay for the Daily Minimum quantity of water at the Contract Rate. "Daily Minimum" shall mean:

(i) One hundred thousand (100,000) gallons of water a day (0.10 million gallons per day (mgd)), or

(ii) Such greater amount as may be elected under paragraph
7 (b) of this Agreement.

(b) At any time during the term of this Agreement, Rahway may elect, upon written notification to Middlesex, to increase the Daily Minimum quantity of water to a greater quantity of water (hereinafter referred to as the "Revised Daily Minimum"). Once such an election is made by Rahway, the Revised Daily Minimum quantity of water shall remain in effect for a period of at least twelve
(12) months from the effective date of such election unless further increased pursuant to this Agreement. At the end of such twelve (12) month period, the Revised Daily Minimum shall remain in effect unless Rahway shall further amend (increase or decrease) the Revised Daily Minimum. Each such election to amend shall be on written notice to Middlesex and shall remain in effect for a period of twelve (12) months from the effective date of such election unless further increased pursuant to this Agreement. Any election to decrease the Revised Daily Minimum shall not be reduced below the initial amount of one hundred thousand (100,000) gallons of water a day specified in paragraph 7(a)(i) of this Agreement.

8. Peaking Charges.

(a) The total daily quantity of water taken by Rahway at the Meter Stations may exceed the Daily Minimum or the Revised Daily Minimum by up to 50% on a 24-hour basis without affecting the Contract Rate. The quantity of water taken in the peak hour multiplied by 24 may exceed the Daily Minimum or the Revised Daily Minimum by up to 100% without affecting the Contract Rate. Such excess quantities of water are known as the "Allowable Excess".

-4-

(b) If the quantity of water taken in a 24-hour period shall exceed the Daily Minimum or the Revised Daily Minimum by more than 50%, ("Daily Peaking Excess"), Rahway shall pay for such Daily Peaking Excess at a rate (the "Daily Peaking Rate") determined by the following formula:

(i)      A  fraction  (the  numerator  of which is the  actual
         daily  usage;  and the  denominator  of  which is the
         applicable  Daily  Minimum or Revised  Daily  Minimum
         then in effect  multiplied by 1.5)  multiplied by the
         Contract Rate. For example, if the actual daily usage
         is .25 million gallons,  and the Daily Minimum is .10
         million gallons and the Contract Rate is

         $1,500.00:
               .25        x    Contract Rate
         ---------
         .10 x 1.5

         1.67             x    $1,500.00 = $2,505.00 (Daily
                                                      Peaking
                                                        Rate)

In this example, the charge for the Daily Peaking Excess would be $250.00 calculated as follows:

.25 - .15 (Allowable Excess) = .10 (Daily Peaking Excess) .10 x $2,505.00 = $250.50

(c) If the quantity of water supplied in the maximum peak hour multiplied by 24 shall exceed the Daily Minimum or the Revised Daily Minimum by more than 100%, ("Hourly Peaking Excess") Rahway shall pay for such Hourly Peaking Excess with a charge (the "Hourly Peaking Charge") determined by the following formula:

(i) A fraction (the numerator of which is the quantity of water supplied in the maximum peak hour multiplied by 24; and the denominator of which is the applicable Daily Minimum or Revised Daily Minimum then in effect multiplied by 2.0) multiplied by the

Contract Rate.

For example, if the quantity of water
supplied in the maximum peak hour multiplied
by 24 equals .30 million gallons; and the

-5-

Daily Minimum is .10 million gallons and the
Contract Rate is

$1,500.00:
      .30     x    Contract Rate
---------
  .10 x 2

1.50 x $1,500.00 = $2,250.00
(Hourly Peaking Charge)

In this example, the charge for such Hourly Peaking Excess would be calculated as follows:

300,000 gal. / 24 = 12,500

200,000 gal. / 24 = 8,333

Calculated maximum

Peak hour excess =
                 12,500 - 8,333 = 4,167 gal.

Hourly Peaking Charge x Calculated Max. Peak
Hour Excess

$2,250 mgd                   4,167 gal.
$2,250 mgd            x    .004167

= $9.375 for such Hourly Peaking Excess

A similar calculation would be made for each
day there is an Hourly Peaking Excess, but
there shall not be more than one such Hourly
Peaking Charge in each 24-hour period.

(d) In no instance, and under no conditions, shall the daily 24-hour quantity of water supplied and purchased under this Agreement exceed One (1) million gallons, nor shall the maximum hourly flow exceed the rate of Two (2) million gallons per day, unless otherwise agreed in writing by the parties.

(e) Notwithstanding anything herein to the contrary, the obligation of Middlesex to supply water under this Agreement beyond the Daily Minimum or the Revised Daily Minimum, as the case may be, is subject to Middlesex having the supply and capacity to provide such amounts.

9. Exceptions for Special Circumstances

Notwithstanding anything to the contrary herein, the parties recognize that at different times during the year, Rahway experiences a problem with excess chloride in its

-6-

water (the "Chloride Issue"). In addition, at different times during the year, Rahway experiences an additional passing flow problem whereby it is required to cease taking, or decrease the amount of, water which it may legally take from the Rahway River (the "Passing Flow Issue").

In the event that Rahway is experiencing either of these problems throughout the year and properly notifies Middlesex of such problems, and the expected duration of the same, then and in such event, Middlesex agrees that Rahway shall be obligated to pay for the amount of water needed to address each such problem according to the following schedule:

(a) For the daily amount of water used for the Chloride Issue during the period from October 1 - April 30, Rahway shall pay for such water at the Contract Rate set forth herein without regard to any additional Peaking Charges as set forth in paragraph 8 hereof.

(b) For the daily amount of water used for the Passing Flow Issue during the period from October 1 - April 30, Rahway shall pay for such water at the Contract Rate set forth herein without regard to any additional Peaking Charges as set forth in paragraph 8 hereof.

(c) For the daily amount of water used for the Chloride Issue during the period from May 1 - September 30, Rahway shall pay for such water at the Contract Rate set forth herein without regard to any additional Peaking Charges as set forth in paragraph 8 hereof, provided that the amount of water used for the Chloride Issue does not exceed one million gallons per day. For any amounts of water used in excess of one million gallons per day, Rahway shall pay for such excess at a Daily Peaking Rate as determined under paragraph 8 hereof.

(d) For the daily amount of water used for the Passing Flow Issue during the period from May 1 - September 30, Rahway shall pay for such water in accordance with the provisions of paragraphs 7 and 8 herein, except that the amount charged as the Daily Peaking Rate shall not exceed and shall be capped at the rate for one million gallons under the Consumption Charges as set forth in Rate Schedule No. 1 - General Water Service - GS (the "Retail Rate") then in effect under the applicable Middlesex Tariff. As

-7-

of the date of the Agreement, the Retail Rate is the equivalent of $2,938.70 per million gallons of water used.

10. Payment.

The terms are net cash on presentation of invoice.

11. Combined Charge.

Payments for water (in excess of the Daily Minimum or the Revised Daily Minimum and adjustments of the Daily Minimum or the Revised Daily Minimum under paragraph 7) shall be determined on the basis of the combined total daily quantity of water supplied through all the Meter Stations as determined by meter readings at said Meter Stations.

12. Meter Readings.

Middlesex will read the meters daily (at a regular hour determined by Middlesex) for all water supplied to Rahway at each connection then in operation.

13. Definitions.

Where the words "daily" or "24 hours" are used in this contract, they shall refer to the 24-hour period between the daily meter readings.

14. Quality.

All water delivered to Rahway by Middlesex under this Agreement is intended to comply with all Federal and State primary requirements for safe drinking water.

15. Scheduling.

Middlesex shall have the right to modify its rate of delivery to manage its system requirements in accordance with accepted operating procedures. Rahway shall give Middlesex reasonable advance notice of any anticipated departures from its then normal usage.

16. Exceptions for Emergencies.

The Daily Minimum or Revised Daily Minimum payment obligation shall not be affected in the event that the amount of water supplied by Middlesex to Rahway exceeds the daily or hourly limitations established herein for not more than twenty-four (24) hours in case of documented fire or main break emergencies experienced by Rahway and for not more that five (5) days in the case of other exceptional circumstances experienced by Rahway requiring an emergency supply of water, provided Middlesex is promptly

-8-

notified that any such emergency exists. It is at the sole reasonable discretion of Middlesex to determine if such requests meet the criteria of an emergency as contemplated in this Agreement.

17. Excused Performance.

Middlesex agrees to provide a continuous, regular and uninterrupted supply of water at the Meter Stations, subject to delays in initiating service or interruptions in service by reasons of acts of God, accident, strike, legal process, or other cause beyond its control, or failure, refusal, or delay on the part of any governmental or regulatory body having jurisdiction in issuing permits, approvals, authorizations, licenses, rights-of-way or the like. Middlesex shall not be liable for damages to Rahway by reason of inadequate pressure or volume or quality or failure to provide water for any cause whatsoever provided that the same does not arise out of the negligence of Middlesex. In the event of an interruption in service Middlesex agrees to act diligently within the bounds of normal operating procedures to return service to normal.

18. Indemnification.

Rahway shall completely indemnify, protect and save harmless Middlesex from any and all costs, expenses, liability, losses, claims, suits and proceedings of any nature whatsoever arising out of the water service by Rahway. However, as to claims involving water quality, this paragraph is intended not to apply to water until after it is delivered to Rahway system, i.e., after water is supplied through points of delivery referred to in paragraph 5.

Middlesex shall completely indemnify, protect and save harmless Rahway from all costs, expenses, liability, losses, claims, suits and proceedings of any nature whatsoever caused by any breach by Middlesex of its obligations under this Agreement.

Notwithstanding anything herein to the contrary, each party's aggregate liability to the other arising out of or in connection with this Agreement shall not exceed an amount equal to two times one year's gross revenues required to be paid by Rahway to Middlesex based upon the Daily Minimum or Revised Daily Minimum in effect at the time of the occurrence giving rise to the liability, and each party hereby releases the other from any liability in excess thereof. This paragraph is not intended to limit either party's liability to third parties.

-9-

19. Regulatory Approvals.

This Agreement shall be filed with and subject to approval by the BPU and the New Jersey Department of Environmental Protection as may be required by law.
Middlesex shall expeditiously initiate the said filings for the said approvals. Both parties agree to cooperate and act in good faith in connection with obtaining these and any other regulatory authorizations.

20. Miscellaneous.

To the extent not inconsistent with this Agreement, all other provisions of Middlesex's tariff shall be deemed to govern service hereunder.

This Agreement shall be governed by and interpreted in accordance with the laws of the State of New Jersey.

-10-

IN WITNESS WHEREOF, the parties have caused this Agreement to be duly executed as of the day and year first written above.
