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 June 30, 2006 and the results of operations for the three and six month periods ended June 30, 2006 and 2005, and cash flows for the six month periods ended June 30, 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 July 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 48 (FIN 48) "Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109", to clarify certain aspects of accounting for uncertain tax positions, including recognition and measurement of those tax positions. This interpretation is effective for fiscal years beginning after December 15, 2006. The Company is in the process of evaluating the impact of the adoption of this interpretation on the Company's results of operations and financial condition. On March 31, 2006, the FASB issued an exposure draft that would require recognition of the overfunded or underfunded positions of defined benefit pension and other postretirement plans on the balance sheet. For an underfunded plan, the incremental liability to be recorded would be equal to the difference between the projected benefit obligation and the fair value of plan assets. Statement of Financial Accounting Standard No. 87, "Employers' Accounting for Pensions" (SFAS 87) and SFAS No. 106, "Employers' Accounting for Postretirement Benefits Other Than Pensions" (SFAS 106) allow for deferred recognition of this liability through amortization of this difference over time. Under this exposure draft, actuarial gains and losses and prior service costs and credits that arise during the period but, pursuant to SFAS 87 and SFAS 106 are not yet recognized as components of net periodic benefit cost, would be recognized as a component of Other Comprehensive Income (net of tax). The exposure draft also would require an adjustment to the beginning balance of retained earnings (net of tax) for any transition obligation remaining from the initial application of SFAS 87 and 106. Such amounts would subsequently not be amortized as a component of net periodic benefit cost. 5

If the exposure draft is adopted as proposed, such amounts not yet recognized would result in a material reduction of the Company's shareholders' equity, and thus have an adverse impact on its current rate-making methodology. Accordingly, the Company would petition the New Jersey Board of Public Utilities (BPU) to seek to have the amounts recognized as Other Comprehensive Income treated as a Regulatory Asset and amortize these costs in rates. The Company is unable to predict the ultimate regulatory treatment that would be applied if a pronouncement were adopted according to the exposure draft in its present form. 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 request is intended to recover increased costs of operations, maintenance and taxes, as well as capital investment of approximately $23.8 million since rates were last established in March 2005. We cannot predict whether the PSC will ultimately approve, deny, or reduce the amount of the request. Concurrent with the rate filing, Tidewater also submitted a request for a 15% interim rate increase subject to refund as allowed under PSC regulations. The interim rates went into effect on June 27, 2006. 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. These increases represent a total base rate increase of approximately $0.1 million for Pinelands to offset 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. Note 2 - Capitalization Common Stock -During the six months ended June 30, 2006, there were 35,553 common shares (approximately $0.8 million) issued under the Company's Dividend Reinvestment and Common Stock Purchase Plan. Long-term Debt - On July 19, 2006, Middlesex received approval from the BPU 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. 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. On May 31, 2006, the Company closed on the loan with an established interest rate of 4.03%. 6

Note 3 - 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 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 June 30, 2006, the Company has established lines of credit aggregating $38.0 million. At June 30, 2006, the outstanding borrowings under these credit lines were $12.6 million at a weighted average interest rate of 5.80%. As of that date, the Company had borrowing capacity of $25.4 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 $9.2 million and $12.0 million at 5.91% and 4.36% for the three months ended June 30, 2006 and 2005, respectively. The weighted average daily amounts of borrowings outstanding under the Company's credit lines and the weighted average interest rates on those amounts were $7.6 million and $11.1 million at 5.82% and 4.11% for the six months ended June 30, 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 in addition, 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 June 30, 2006, approximately $23.9 million of the Series C Serial Bonds remained outstanding. Middlesex is 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 that may be implemented by Perth Amboy 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. 9

Purchased water costs are shown below: (Dollars in Millions) Three Months Ended Six Months Ended June 30, June 30, 2006 2005 2006 2005 ------------------------------------- Purchased Water Treated $ 0.5 $ 0.5 $ 1.1 $ 1.1 Untreated 0.4 0.5 0.9 0.9 ------------------------------------- Total Costs $ 0.9 $ 1.0 $ 2.0 $ 2.0 ------------------------------------- Construction - The Company expects to spend approximately $37.8 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. 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 required 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. 10

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 contributed $1.3 million of cash to the plan in July 2006. In addition, the Company maintains an unfunded supplemental pension plan for seven company officers. 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 in the fourth quarter of 2006. The following table sets forth information relating to the Company's periodic costs for its retirement plans. (Dollars in Thousands) Pension Benefits Other Benefits ---------------- -------------- Three Months Ended June 30, 2006 2005 2006 2005 ----------------------------------- Service Cost $ 334 $ 283 $ 189 $ 153 Interest Cost 425 381 201 193 Expected Return on Assets (402) (384) (83) (69) Amortization of Unrecognized Losses 62 3 111 120 Amortization of Unrecognized Prior Service Cost 3 23 -- -- Amortization of Transition Obligation -- -- 34 34 ----------------------------------- Net Periodic Benefit Cost $ 422 $ 306 $ 452 $ 431 ----------------------------------- Pension Benefits Other Benefits ---------------- -------------- Six Months Ended June 30, 2006 2005 2006 2005 ----------------------------------- Service Cost $ 644 $ 565 $ 366 $ 306 Interest Cost 855 762 419 385 Expected Return on Assets (816) (768) (174) (137) Amortization of Unrecognized Losses 119 7 240 240 Amortization of Unrecognized Prior Service Cost 3 46 -- -- Amortization of Transition Obligation -- -- 68 68 ----------------------------------- Net Periodic Benefit Cost $ 805 $ 612 $ 919 $ 862 ----------------------------------- Note 8 - Stock Based Compensation The Company recognizes compensation expense at fair value for its restricted stock awards in accordance with SFAS 123(R). The adoption of this standard on January 1, 2006 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 June 30, 2006 for key employees. Such stock is subject to an 11

agreement requiring forfeiture by the employee in the event of termination of employment within five years of 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 six months ended June 30, 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 June 30, 2006 and 2005 was $0.1 million. Compensation expense for the six months ended June 30, 2006 and 2005 was $0.1 million. Total unearned compensation related to restricted stock was $0.6 million at June 30, 2006.

For an additional discussion of factors that may affect the Company's business and results of operations, see Item 1A. - Risk Factors in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2005. 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 29,100 retail customers in New Castle, Kent, and Sussex Counties, Delaware. Our TESI subsidiary provides regulated wastewater service to approximately 30 residential retail customers. White Marsh serves 4,000 customers 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 regulated water services to customers in our franchise 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 since the end of 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. 14

Recent Developments Rate Increases 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 rates were last established in March 2005. We cannot predict whether the PSC will ultimately approve, deny, or reduce the amount of the request. Concurrent with the rate filing, Tidewater also submitted a request for a 15% interim rate increase subject to refund, as allowed under PSC regulations. The interim rates went into effect on June 27, 2006. 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. These increases represent a total base rate increase of approximately $0.1 million for Pinelands to offset 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 six months ended June 30, 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. 15

Results of Operations - Three Months Ended June 30, 2006 (Thousands of Dollars) Three Months Ended June 30, --------------------------- 2006 2005 ---- ---- Non- | Non- Regulated Regulated Total | Regulated Regulated Total --------- --------- ----- | --------- --------- ----- Revenues $ 18,663 $ 2,374 $ 21,037 | $ 16,393 $ 2,038 $ 18,431 Operations and maintenance expenses 8,921 1,885 10,806 | 8,593 1,795 10,388 Depreciation expense 1,683 30 1,713 | 1,594 26 1,620 Other taxes 2,313 56 2,369 | 2,102 62 2,164 ----------------------------------------------------------------------- Operating income 5,746 403 6,149 | 4,104 155 4,259 ----------------------------------------------------------------------- | Other income 144 -- 144 | 160 -- 160 Interest expense 1,784 24 1,808 | 1,555 23 1,578 Income taxes 1,365 152 1,517 | 842 53 895 ----------------------------------------------------------------------- Net income $ 2,741 $ 227 $ 2,968 | $ 1,867 $ 79 $ 1,946 ----------------------------------------------------------------------- Operating revenues for the three months ended June 30, 2006 increased $2.6 million, or 14.1%, from the same period in 2005. Water sales improved by $1.4 million in our New Jersey systems, of which $1.1 million was a result of a base rate increase that was granted to Middlesex on December 8, 2005, and $0.3 million was due to additional consumption as a result of favorable weather. Revenues rose in our Delaware service territories by $0.9 million. Higher water consumption sales by our existing customers contributed $0.3 million in revenue, customer growth contributed $0.2 million of water sales, and base rate increases provided an additional $0.1 million. Connection fee revenues contributed an additional $0.3 million in Delaware. USA-PA contributed an additional $0.2 million related to additional services provided to the City of Perth Amboy. New unregulated wastewater contracts in Delaware provided $0.1 million of additional revenues. Revenues for all other operations were comparable to the prior year period. 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. Customer growth in both the regulated water and wastewater businesses are dependent upon economic conditions surrounding new housing as well as developer construction timetables. 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 4.0%. In New Jersey, payroll and benefits costs increased $0.1 million. The continued growth of our Delaware systems resulted in $0.1 million of increases for the cost of water treatment, insurance and additional employees and related benefit costs. Wastewater treatment costs for White Marsh increased by $0.1 million. All other operating expenses increased $0.1 million. We are experiencing increases in electric generation costs 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 5.7%, primarily as a result of a higher level of utility plant in service since June 30, 2005. 16

Other taxes increased by $0.2 million, reflecting taxes on increased taxable gross revenues in New Jersey. Interest expense increased by $0.2 million, primarily due to higher average long-term borrowings as compared to the prior year period. Income taxes increased by $0.6 million as a result of increased operating income as compared to the prior year period. Net income increased by 52.5% from $1.9 million to $3.0 million. Basic earnings per share increased from $0.17 to $0.25 due to the increase in earnings. Diluted earnings per share increased from $0.16 to $0.25. Results of Operations - Six Months Ended June 30, 2006 (Thousands of Dollars) Six Months Ended June 30, ------------------------- 2006 2005 ---- ---- Non- | Non- Regulated Regulated Total | Regulated Regulated Total --------- --------- ----- --------- --------- ----- Revenues $ 34,663 $ 4,604 $ 39,267 | $ 31,152 $ 4,022 $ 35,174 Operations and maintenance expenses 17,432 3,759 21,191 | 16,841 3,488 20,329 Depreciation expense 3,324 57 3,381 | 3,121 47 3,168 Other taxes 4,458 115 4,573 | 4,123 124 4,247 --------------------------------------------------------------------------- Operating income 9,449 673 10,122 | 7,067 363 7,430 --------------------------------------------------------------------------- | Other income 313 -- 313 | 417 -- 417 Interest expense 3,273 50 3,323 | 2,914 46 2,960 Income taxes 2,082 250 2,332 | 1,430 131 1,561 --------------------------------------------------------------------------- Net income $ 4,407 $ 373 $ 4,780 | $ 3,140 $ 186 $ 3,326 --------------------------------------------------------------------------- Operating revenues for the six months ended June 30, 2006 increased $4.1 million, or 11.6%, from the same period in 2005. Water sales improved by $2.4 million in our New Jersey systems, of which $2.1 million was a result of a base rate increase that was granted to Middlesex on December 8, 2005, and $0.3 million was due to additional consumption as a result of favorable weather. Revenues rose in our Delaware service territories by $1.1 million. Higher water consumption sales by our existing customers contributed $0.3 million in revenue, customer growth contributed $0.4 million of water sales, and base rate increases provided an additional $0.2 million. Connection fee revenues contributed an additional $0.2 million in Delaware. USA-PA contributed an additional $0.3 million related to additional services provided to the City of Perth Amboy. New unregulated wastewater contracts in Delaware provided $0.2 million of additional revenues. All other operations accounted for $0.1 million of additional revenues. Operation and maintenance expenses increased $0.9 million, or 4.2%. Pumping and water treatment costs for our Middlesex system increased a combined $0.3 million due to higher costs for electricity, chemicals and disposal of residuals. This increase was partially offset by $0.1 million of reduced cost of repairs to the Middlesex system. In New Jersey, corporate governance related fees and bill production costs increased $0.1 million. As previously discussed, the continuing growth of our Delaware systems resulted in higher costs of water treatment, additional employees and related benefit expenses, and corporate governance related fees of $0.3 million. Costs related to providing services by our non-regulated wastewater operation in Delaware increased by $0.2 million. All other operating costs increased by $0.1 million. 17

Depreciation expense increased $0.2 million, or 6.7%, due to the higher level of utility plant in service, as discussed for the three-month results. Other taxes increased by $0.3 million, reflecting taxes on higher taxable gross revenues in New Jersey. Other income decreased $0.1 million, primarily due to reduced Allowance for Funds Used During Construction as a result of the timing of spending for capital projects in New Jersey and Delaware as compared to the prior year. Also, while overall capital spending increased from $11.6 million to $11.9 million, our TESI subsidiary acquired a $1.4 million wastewater system during 2006 rather than construct it. Interest expense increased by $0.4 million, primarily due to higher average long-term borrowings as compared to the prior year. Income taxes increased by $0.8 million as a result of increased operating income as compared to the prior year. Net income increased by $1.5 million, or 43.7%, and basic and diluted earnings per share increased from $0.28 to $0.40 per share. The earnings per share increase was due to the higher net income. 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 six months ended June 30, 2006, cash flows from operating activities were $7.4 million, an increase of $2.7 million from the prior year. This increase was attributable to increased earnings, the timing of collection of customer receivables and payments for taxes. These increases were partially offset by the timing of payments to vendors and payments of interest. The $7.4 million of net cash flow from operations allowed us to fund 62% of our utility plant expenditures internally for the period, with the remainder funded with proceeds from equity issued under our Dividend Reinvestment Plan and short-term borrowings. The Company's capital program for 2006 is estimated to be $37.8 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 $7.2 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, $3.9 million), which provide low cost financing for projects that meet certain water quality and system improvement benchmarks. We also expect to utilize short-term borrowings through $38.0 million of available lines of credit with several financial institutions. As of June 30, 2006, $12.6 million was outstanding against the lines of credit. 18

On July 19, 2006, Middlesex received approval from the BPU to issue up to $4.0 million of first mortgage bonds through the NJEIT. The Company expects to close on the bonds in November 2006. The proceeds from this financing will be used to fund the 2007 RENEW program. 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. On May 31, 2006, the Company closed on the loan with an established interest rate of 4.03%. The Company periodically issues shares of common stock in connection with our dividend reinvestment and stock purchase plan (DRP). From time to time, the Company may issue additional equity to reduce short-term indebtedness, fund our capital program, and for other general corporate purposes. Middlesex has filed an application with the BPU seeking approval to issue up to 1.5 million shares of common stock before the end of 2006. Going forward into 2007 through 2008, we currently project that we will expend between $85.9 million and $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, proceeds from the DRP, and the proceeds from the 1.5 million share common stock offering to pay for our capital program. 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 $2.1 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 changes in the Company's internal controls or in other factors, which materially affected internal controls during the quarter ended June 30, 2006. 19

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 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.
