PROSPECTUS SUMMARY
      This Prospectus Summary calls your attention to the most significant aspects of the offering covered by this document, but may not contain all the information that is important to you. Unless otherwise indicated, we have assumed in presenting information about outstanding shares of common stock, including per share information, that the underwriters’ over-allotment option will not be exercised. The terms “Company,” “we,” “our,” and “us” refer to Middlesex Water Company and its subsidiaries, including Tidewater Utilities, Inc. (“Tidewater”) (and Tidewater’s wholly-owned subsidiaries, Southern Shores Water Company, LLC (“Southern Shores”) and White Marsh Environmental Systems, Inc. (“White Marsh”)), Tidewater Environmental Services, Inc. (“TESI”), Pinelands Water Company (“Pinelands Water”) and Pinelands Wastewater Company (“Pinelands Wastewater” and collectively with Pinelands Water, “Pinelands”), Utility Service Affiliates, Inc. (“USA”), and Utility Service Affiliates (Perth Amboy) Inc., (“USA-PA”). The term “you” refers to a prospective investor. The term “Middlesex System” refers to our central New Jersey water utility. To understand the offering fully and for a more complete description of the offering you should read this entire document carefully, including especially the “Risk Factors” section, as well as the documents to which we have referred you in the section entitled “Where You Can Find More Information.”
Our Business
      Middlesex Water 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 domestic, 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 the rates charged to customers for water and wastewater services, as to the quality of water service we provide and as to certain other matters. Only our USA, USA-PA and White Marsh subsidiaries are not regulated utilities.
      Our Middlesex System provides water service 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 294,000. Through our subsidiary, USA-PA, we operate the water supply system and wastewater system for the City of Perth Amboy, New Jersey. Our other New Jersey subsidiaries, Pinelands Water and Pinelands Wastewater, provide water and wastewater services to residents in Southampton Township, New Jersey. Our USA subsidiary offers residential customers in New Jersey and Delaware a service line maintenance program called LineCaresm.
      Our Delaware subsidiaries, 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 in Delaware. Our White Marsh subsidiary serves an additional 4,000 customers under unregulated operating contracts with various owners of small water and wastewater systems in Kent and Sussex Counties. Our customer base in Delaware has the potential to grow substantially within the existing territories we currently serve. The developments we either serve or have entered into contracts to serve have obtained approvals to build additional housing units. If those additional housing units are built and sold, we project our customer base would grow to 41,000 without the acquisition of additional housing developments. Further, there is significant economic development and population growth within and near many of our Delaware service areas. For example, according to the United States Census Bureau, from 2000 to 2005, the population in Kent and Sussex Counties is estimated to have increased 13.6% and 12.7%, respectively.

Our Strategy
      Our strategy is focused on four key areas:
  •  Serve as a trusted and continually-improving provider of safe, reliable and cost-effective water, wastewater and related services.
 
  •  Provide a comprehensive suite of water and wastewater solutions in the rapidly developing Delaware market that results in profitable growth.
 
  •  Pursue profitable, core growth in New Jersey.
 
  •  Invest in products, services and other viable opportunities that complement our core competencies.
Recent Developments
Earnings for Six Months ended June 30, 2006
      For the six months ended June 30, 2006, our revenues were $39.3 million, an increase of $4.1 million from the same period in 2005. Water sales increased by $0.6 million resulting from hot, dry weather. Base rate increases contributed $2.3 million of the increase. Water consumption and related fees from customer growth, primarily in the Delaware subsidiaries, added $0.6 million of the increase, while additional revenues from other sources contributed $0.6 million. Operating expenses increased to $21.2 million, an increase of $0.9 million over the same period in 2005. Approximately $0.3 million of this increase is due to increased costs for wages and benefits, some of which is resulting from the addition of employees to support growth. Pumping and water treatment costs for our Middlesex System increased by $0.3 million. The remaining $0.3 million of the increase relates to a combination of additional wastewater treatment costs in Delaware and various miscellaneous items.
      We reported earnings applicable to common stock of $2.9 million, or $0.25 per share, for the quarter ended June 30, 2006, compared with $1.9 million, or $0.16 per share for the same period in 2005.
Tidewater Rate Request
      In April 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.

RISK FACTORS
      We have described for you below risks involved in investing in the common stock offered under this prospectus. You should carefully consider each of the following factors and all of the information both in this prospectus and in the other documents we have filed with the Securities and Exchange Commission which are incorporated in this prospectus by reference.
Our revenue and earnings depend on the rates we charge our customers. We cannot raise utility rates in our regulated businesses without filing a petition with the appropriate governmental agency. If these agencies modify, delay, or deny our petition, our revenues will not increase and our earnings will decline unless we are able to reduce costs.
      The New Jersey Board of Public Utilities (“BPU”) regulates our public utility companies in New Jersey with respect to rates and charges for service, classification of accounts, awards of new service territory, acquisitions, financings and other matters. That means, for example, that we cannot raise the utility rates we charge to our customers without first filing a petition with the BPU and going through a lengthy administrative process. In much the same way, the PSC regulates our public utility companies in Delaware. We cannot give assurance of when we will request approval for any such matter, nor can we predict whether the BPU or PSC will approve, deny or reduce the amount of such requests.
      Certain costs of doing business are not completely within our control. The failure to obtain any rate increase would prevent us from increasing our revenues and, unless we are able to reduce costs, would result in reduced earnings.
We are subject to environmental and safety laws and regulations, including water quality and wastewater effluent quality regulations, as well as other state and local regulations. Compliance with these laws and regulations requires us to incur costs and we are subject to fines or other sanctions for non-compliance.
      The United States Environmental Protection Agency (“EPA”) and New Jersey Department of Environmental Protection (“DEP”) regulate our operations in New Jersey with respect to water supply, treatment and distribution systems and the quality of the water. Our operations in Delaware are regulated by the EPA, Delaware Department of Natural Resources and Environmental Control (“DNREC”), Delaware Department of Health and Social Services-Division of Public Health (“DPH”), and Delaware River Basin Commission (“DRBC”) with respect to water supply, treatment and distribution systems and the quality of water. Federal, New Jersey and Delaware regulations relating to water quality require us to perform expanded types of testing to ensure that our water meets state and federal water quality requirements. We are subject to EPA regulations under the Federal Safe Drinking Water Act, which include the Lead and Copper Rule, the maximum contaminant levels established for various volatile organic compounds, the Federal Surface Water Treatment Rule and the Total Coliform Rule. There are also similar state regulations by the DEP in New Jersey. The DEP and DPH monitor our activities and review the results of water quality tests that we perform for adherence to applicable regulations. In addition, environmental regulatory agencies are continually reviewing regulations governing the limits of certain organic compounds found in water as byproducts of treatment.
      We are also subject to regulations related to fire protection services. In Delaware, fire protection is regulated statewide by the Office of State Fire Marshal. In New Jersey there is no state-wide fire protection regulatory agency, but state regulations exist as to the size of piping required regarding the provision of fire protection services.
      The cost of compliance with the water and wastewater effluent quality standards depends in part on the limits set in the regulations and on the method selected to implement them. If new or more restrictive standards are imposed, the cost of compliance could be very high and have an adverse impact on our revenues and results of operations if we cannot recover those costs through our rates that we charge our customers. The cost of compliance with fire protection requirements could also be high and make us less profitable if we cannot recover those costs through our rates charged to our customers.

Table of Contents

      In addition, if we fail to comply with environmental or other laws and regulations to which our business is subject, we could be fined or subject to other sanctions, which could adversely impact our business or results of operations.
We are currently appealing a notice of violation and request for corrective action issued by the Delaware Fire Marshal regarding the alleged failure of one of the community water systems operated by Tidewater to meet Delaware fire protection requirements. If our appeal is unsuccessful, our operating results could be materially affected.
      In July 2005, Tidewater received a notice of violation and request for corrective action issued by the Delaware Fire Marshal regarding the alleged failure of one of the community water systems operated by Tidewater to meet Delaware fire protection requirements. Tidewater appealed the Fire Marshal’s decision with the Delaware State Fire Prevention Commission (the “SFPC”) and, in November 2005, the SFPC denied Tidewater’s appeal. In December 2005, Tidewater filed an appeal of the SFPC’s decision with the Sussex County Superior Court in Delaware, which is still pending. There are approximately 67 of our other systems that may not meet the Delaware Fire Marshal’s recent interpretation of the fire protection requirements. If the Delaware Fire Marshal’s interpretation of the regulations is upheld upon appeal, we may be required to make corrections to the system at issue and the Delaware Fire Marshal could issue notices of violation and requests for corrective action for some or all of the approximately 67 other community systems. At this time, we cannot predict how many community water systems would ultimately require corrective action if our appeal is unsuccessful nor can we predict the timing and the cost of any required corrective actions. We will apply to the PSC to increase base rates to recover the costs of any such corrective actions. However, if corrective actions need to be taken at several community water systems, our costs could be significant, and to the extent the PSC does not approve rate increases to offset these costs, or if there is a significant delay in receiving approval for such rate increases, such costs could have a material adverse effect on our operating results.
We depend upon our ability to raise money in the capital markets to finance some of the costs of complying with laws and regulations, including environmental laws and regulations, or to pay for some of the costs of improvements to or expansion of our utility system assets. Our regulated utility companies cannot issue debt or equity securities without regulatory approval.
      We require financing to fund our ongoing capital program for the improvement of our utility system assets and for planned expansion of those systems. We expect to spend between $86 million and $112 million for capital projects through 2008. We must obtain regulatory approval to sell debt or equity securities to raise money for these projects. If sufficient capital is not available, the cost of capital is too high, or if the regulatory authorities deny a petition of ours to sell debt or equity securities, we may not be able to meet the costs of complying with environmental laws and regulations or the costs of improving and expanding our utility system assets to the level we believe necessary. This might result in the imposition of fines or restrictions on our operations and may curtail our ability to improve upon and expand our utility system assets.
Weather conditions and overuse of underground aquifers may interfere with our sources of water, demand for water services and our ability to supply water to customers.
      Our ability to meet the existing and future water demands of our customers depends on an adequate supply of water. Unexpected conditions may interfere with our water supply sources. Drought and overuse of underground aquifers may limit the availability of ground and/or surface water. Freezing weather may also contribute to water transmission interruptions caused by pipe and/or main breakage. Any interruption in our water supply could cause a reduction in our revenue and profitability. These factors might adversely affect our ability to supply water in sufficient quantities to our customers. Governmental drought restrictions might result in decreased use of water services and can adversely affect our revenue and earnings.

Table of Contents

Our business is subject to seasonal fluctuations, which could affect demand for our water service and our revenues.
      Demand for our water during the warmer months is generally greater than during cooler months due primarily to additional consumption of water in connection with irrigation systems, swimming pools, cooling systems and other outside water use. Throughout the year, and particularly during typically warmer months, demand may vary with temperature and rainfall levels. In the event that temperatures during the typically warmer months are cooler than normal, or if there is more rainfall than normal, the demand for our water may decrease and adversely affect our revenues.
Our water sources may become contaminated by naturally-occurring or man-made compounds and events. This may cause disruption in services and impose costs to restore the water to required levels of quality.
      Our sources of water may become contaminated by naturally-occurring or man-made compounds and events. In the event that our water supply is contaminated, we may have to interrupt the use of that water supply until we are able to install treatment equipment or substitute the flow of water from an uncontaminated water source through our transmission and distribution systems. We may also incur significant costs in treating the contaminated water through the use of our current treatment facilities, or development of new treatment methods. Our inability to substitute water supply from an uncontaminated water source, or to adequately treat the contaminated water source in a cost-effective manner, may reduce our revenues and make us less profitable.
We face competition from other water and wastewater utilities and service providers, which might hinder our growth and reduce our profitability.
      We face risks of competition from other utilities authorized by federal, state or local agencies. Once a state utility regulator grants a franchise to a utility to serve a specific territory, that utility has an exclusive right to service that territory. Although a new franchise offers some protection against competitors, the pursuit of franchises is competitive, especially in Delaware where new franchises may be awarded to utilities based upon competitive negotiation. Competing utilities have challenged, and may in the future challenge, our applications for new franchises. Also, third parties entering into long-term agreements to operate municipal systems might adversely affect us and our long-term agreements to supply water on a contract basis to municipalities, which could adversely affect our operating results.
We have a long-term contractual obligation for water and wastewater system operation and maintenance under which we may incur costs in excess of payments received.
      Middlesex Water Company and USA-PA operate and maintain the water and wastewater systems of the City of Perth Amboy, New Jersey under a 20-year contract expiring in 2018. This contract does not protect us against incurring costs in excess of revenues we earn pursuant to the contract. There can be no assurance that we will not experience losses resulting from this contract. Losses under this contract or our failure or inability to perform may have a material adverse effect on our financial condition and results of operations. Also, in connection with the contract, 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. As of June 30, 2006, approximately $23.9 million of Perth Amboy’s bonds we have guaranteed remain outstanding. If Perth Amboy defaults on its obligations to pay the bonds we have guaranteed, we would have to raise funds to meet our obligations under that guarantee.
An important element of our growth strategy is the acquisition of water and wastewater assets, operations, contracts or companies. Any pending or future acquisitions we decide to undertake may involve risks.
      The acquisition and/or operation of water and wastewater systems is an important element in our growth strategy. This strategy depends on identifying suitable opportunities and reaching mutually agreeable terms with acquisition candidates or contract partners. These negotiations, as well as the integration of acquired

7


Table of Contents

businesses, could require us to incur significant costs and cause diversion of our management’s time and resources. Further, acquisitions may result in dilution of our equity securities, incurrence of debt and contingent liabilities, fluctuations in quarterly results and other related expenses. In addition, the assets, operations, contracts or companies we acquire may not achieve the sales and profitability expected.
The current concentration of our business in central New Jersey and Delaware makes us susceptible to any adverse development in local regulatory, economic, demographic, competitive and weather conditions.
      Our Middlesex System, which accounted for 69% of our 2005 revenue and 68% of our revenue during the first six months of 2006, provides water services to retail customers who are located primarily in eastern Middlesex County, New Jersey and provides water under wholesale contracts to the Township of Edison, the Boroughs of Highland Park and Sayreville, and both the Old Bridge and the Marlboro Township Municipal Utilities Authorities, and the City of Rahway in Union County, New Jersey. Our Tidewater System provides water services to retail customers in the State of Delaware. Our revenues and operating results are therefore subject to local regulatory, economic, demographic, competitive and weather conditions in a relatively concentrated geographic area. A change in any of these conditions could make it more costly or difficult for us to conduct our business. In addition, any such change would have a disproportionate effect on us, compared to water utility companies that do not have such a geographic concentration.
The necessity for increased security has and may continue to result in increased operating costs.
      Since the September 11, 2001 terrorist attacks and the continuing threats to the health and security of the United States of America, we have taken steps to increase security measures at our facilities and heighten employee awareness of threats to our water supply. We have tightened our security measures regarding the delivery and handling of certain chemicals used in our business. We are at risk for terrorist attacks and have incurred, and will continue to incur, increased costs for security precautions to protect our facilities, operations and supplies from such risks.
Our ability to achieve growth in Delaware is somewhat dependent on the residential building market in the territories we serve. If housing starts decline significantly, our rate of growth may not meet our expectations.
      We expect our revenues to increase from customer growth in Delaware for our regulated water operations and, to a lesser degree, our regulated wastewater operations as a result of the anticipated construction and sale of new housing units in the territories we serve. Although the residential building market in Delaware has experienced growth in recent years, this growth my not continue in the future. If housing starts in the Delaware territories we serve decline significantly as a result of economic conditions or otherwise, our revenue growth may not meet our expectations and our financial results could be negatively impacted.
We have restrictions on our dividends. There can be no assurance that we will continue to pay dividends in the future or, if dividends are paid, that they will be in amounts similar to past dividends.
      Our Restated Certificate of Incorporation and our Indenture of Mortgage dated as of April 1, 1927, as supplemented, impose conditions on our ability to pay dividends. We have paid dividends on our common stock each year since 1912 and have increased the amount of dividends paid each year since 1973.
      Our earnings, financial condition, capital requirements, applicable regulations and other factors, including the timeliness and adequacy of rate increases, will determine both our ability to pay dividends on common stock and the amount of those dividends. There can be no assurance that we will continue to pay dividends in the future or, if dividends are paid, that they will be in amounts similar to past dividends.

If we are unable to pay the principal and interest on our indebtedness as it comes due or we default under certain other provisions of our loan documents, our indebtedness could be accelerated and our results of operations and financial condition could be adversely affected.
      Our ability to pay the principal and interest on our indebtedness as it comes due will depend upon our current and future performance. Our performance is affected by many factors, some of which are beyond our control. We believe that our cash generated from operations, and, if necessary, borrowings under our existing credit facilities, will be sufficient to enable us to make our debt payments as they become due. If, however, we do not generate sufficient cash, we may be required to refinance our obligations or sell additional equity, which may be on terms that are not as favorable to us.
      No assurance can be given that any refinancing or sale of equity will be possible when needed or that we will be able to negotiate acceptable terms. In addition, our failure to comply with certain provisions contained in our trust indentures and loan agreements relating to our outstanding indebtedness could lead to a default under these documents, which could result in an acceleration of our indebtedness.
There is a limited trading market for our common stock; you may not be able to resell your shares at or above the price you pay for them.
      Although our common stock is listed for trading on The Nasdaq Global Select Market, the trading in our common stock has substantially less liquidity than many other companies listed on The Nasdaq Global Select Market. A public trading market having the desired characteristics of depth, liquidity and orderliness depends on the presence in the market of willing buyers and sellers of our common stock at any given time. This presence depends on the individual decisions of investors and general economic and market conditions over which we have no control. Because of the limited volume of trading in our common stock, a sale of a significant number of shares of our common stock in the open market could cause our stock price to decline. We cannot provide any assurance that this offering will increase the volume of trading in our common stock.
We depend significantly on the services of the members of our senior management team, and the departure of any of those persons could cause our operating results to suffer.
      Our success depends significantly on the continued individual and collective contributions of our senior management team. If we lose the services of any member of our senior management or are unable to hire and retain experienced management personnel, it could affect our operating results.
We are subject to anti-takeover measures that may be used by existing management to discourage, delay or prevent changes of control that might benefit non-management shareholders.
      Subsection 10A of the New Jersey Business Corporation Act, known as the Shareholder Protection Act, applies to us. The Shareholder Protection Act deters merger proposals, tender offers or other attempts to effect changes in our control that are not negotiated and approved by our Board of Directors. In addition, we have a classified Board of Directors, which means only one-third of the Directors are elected each year. A classified Board can make it harder for an acquirer to gain control by voting its candidates onto the Board of Directors and may also deter merger proposals and tender offers. Our Board of Directors also has the ability, subject to obtaining BPU approval, to issue one or more series of preferred stock having such number of shares, designation, preferences, voting rights, limitations and other rights as the Board of Directors may fix. This could be used by the Board of Directors to discourage, delay or prevent an acquisition that might benefit non-management shareholders.

USE OF PROCEEDS
      Based on an assumed offering price of $19.00, the net proceeds from the sale of the common stock offered by this prospectus, after deducting the underwriters’ commissions and estimated offering expenses, is estimated to be $23.5 million (or $27.4 million if the underwriters exercise their over-allotment options in full). We expect to use the net proceeds to finance our ongoing construction program and to repay all of our outstanding short-term borrowings, which, as of October 5, 2006, consist of borrowings from PNC Bank ($4.5 million), Bank of America ($9.5 million), and CoBank ($4.9 million). These short-term borrowings were primarily incurred to finance costs associated with our capital program in Delaware, which amounted to $15.8 million for the twelve months ended June 30, 2006.

OUR COMPANY
Overview
      Middlesex Water Company was incorporated as a water utility company in 1897 and owns and operates regulated water and wastewater utility systems in New Jersey and in Delaware. We also operate water and wastewater systems on behalf of others in New Jersey and Delaware.
Middlesex System
      The Middlesex System in New Jersey provides water services to approximately 58,500 retail customers, primarily in eastern Middlesex County, New Jersey and provides water under wholesale contracts to the City of Rahway, Township of Edison, the Boroughs of Highland Park and Sayreville, and both the Old Bridge and the Marlboro Township Municipal Utilities Authorities. The Middlesex System treats, stores and distributes water for residential, commercial, industrial and fire prevention purposes. Under a special contract, the Middlesex System also provides water treatment and pumping services to the Township of East Brunswick. The Middlesex System, through its retail and contract sales, accounted for approximately 69% of our 2005 revenue and 68% of revenue during the first six months of 2006. Revenues for the Bayview System, with water services for approximately 300 customers in Cumberland County, New Jersey, are included in the revenue for the Middlesex System in 2006.
      The Middlesex System’s retail customers are located in an area of approximately 55 square miles in Woodbridge Township, the City of South Amboy, the Boroughs of Metuchen and Carteret, portions of Edison Township and the Borough of South Plainfield in Middlesex County and, to a minor extent, a portion of the City of Rahway and the Township of Clark in Union County. The retail customers include a mix of residential customers, large industrial concerns and commercial and light industrial facilities. These retail customers are located in generally well-developed areas of central New Jersey. The contract customers of the Middlesex System comprise an area of approximately 141 square miles with a population of approximately 294,000.
Tidewater System
      Tidewater, together with its wholly-owned subsidiary, Southern Shores, provides water services to approximately 29,100 retail customers for domestic, commercial and fire protection purposes in over 271 separate community water systems in New Castle, Kent and Sussex Counties, Delaware (the “Tidewater System”). Tidewater has another wholly-owned subsidiary, White Marsh, which operates water and wastewater systems under contract for approximately 4,000 customers and also owns the office building that Tidewater uses as its business office. White Marsh’s rates for water and wastewater operations are not regulated by the PSC. The Tidewater System accounted for approximately 17% of our total revenue in 2005 and 18% of revenue during the first six months of 2006.
Utility Service Affiliates (Perth Amboy)
      USA-PA operates the City of Perth Amboy’s water and wastewater systems under a 20-year agreement, which expires in 2018. Perth Amboy has a population of approximately 40,000 and has approximately 9,600 customers, most of whom are served by both systems. The agreement was effected under New Jersey’s Water Supply Public-Private Contracting Act and the New Jersey Wastewater Public/ Private Contracting Act and requires USA-PA to lease from Perth Amboy all of its employees who currently work on the Perth Amboy water and wastewater systems. Under the agreement, USA-PA receives both fixed and variable fees based on increased system billing. Fixed fee payments were $7.4 million in 2005 and are to increase over the term of the 20-year contract to $10.2 million. USA-PA accounted for approximately 10% of our total revenue in 2005 and 10% of revenue during the first six months of 2006.
      In connection with the agreement with Perth Amboy, we guaranteed a series of Perth Amboy’s municipal bonds in the principal amount of approximately $26.3 million, of which approximately $23.9 million remains outstanding. In connection with the agreement with Perth Amboy, USA-PA entered into a 20-year subcontract with a wastewater operating company for the operation and maintenance of the Perth Amboy

wastewater system. The subcontract provides for the sharing of certain fixed and variable fees and operating expenses.
Pinelands System
      Pinelands Water provides water services to approximately 2,400 residential customers in Burlington County, New Jersey. Pinelands Water accounted for less than 1% of our total revenue in 2005 and less than 1% of our revenue during the first six months of 2006. Pinelands Wastewater provides wastewater services to approximately 2,400 primarily residential retail customers. Under contract, it also services one municipal wastewater system in Burlington County, New Jersey with about 200 residential customers. Pinelands Wastewater accounted for approximately 1% of our total revenue in 2005 and approximately 1% of revenue during the first six months of 2006.
Bayview System
      Our Bayview System provides water service to approximately 300 customers in Cumberland County, New Jersey. The Bayview System formerly was operated by our Bayview Water Company subsidiary, which we merged into Middlesex Water Company effective January 1, 2006. As a result, the revenues for the Bayview System are included within the Middlesex System for the first six months of 2006.
Utility Service Affiliates, Inc.
      USA provides residential customers in New Jersey and Delaware a service line maintenance program called LineCaresm. LineCaresm is an affordable maintenance program that covers all parts, material and labor required to repair or replace specific elements of the customer’s water service line and customer shut-off valve in the event of a failure. USA accounted for less than 1% of our total revenue in 2005 and less than 1% of our revenue during the first six months of 2006.
TESI System
      TESI, which began in 2005, provides wastewater services to approximately 30 residential retail customers in Delaware. TESI contributed less than 1% of our total revenue in 2005 and less than 1% of our revenue for the first six months of 2006.
Our Strategy
      Our strategy is focused on four key areas:
  •  Serve as a trusted and continually-improving provider of safe, reliable and cost-effective water, wastewater and related services.
 
  •  Provide a comprehensive suite of water and wastewater solutions in the rapidly developing Delaware market that results in profitable growth.
 
  •  Pursue profitable, core growth in New Jersey.
 
  •  Invest in products, services and other viable opportunities that complement our core competencies.
Serve as a Trusted and Continually-Improving Provider of Safe, Reliable and Cost-effective Water, Wastewater and Related Services.
      We regularly invest in our facilities to improve the reliability and security of our utility infrastructure. In 2005, we made capital investments towards meeting increasingly stringent federal and state water quality standards and addressing the water supply needs of new and existing customers. As part of this investment, a second raw water pipeline that stretches from the raw water pumping station on the Delaware & Raritan Canal in New Brunswick, New Jersey to our primary water treatment plant in Edison, New Jersey went into operation in early March 2005. The second pipeline is providing additional security and reliability and added capacity to our water distribution system.

      We also continue to improve our central New Jersey distribution system by cleaning and cement lining unlined pipe through our RENEW Program (“RENEW”). In 2006, we expect to clean and line five miles of water main in the Iselin and Colonia sections of Woodbridge Township, New Jersey. This program helps eliminate interior pipe restrictions and improves water quality and flow. In addition to rehabilitating the older water mains, RENEW provides for new valves, hydrants and service lines to be installed where necessary. Since establishing RENEW in 1995, we have rehabilitated approximately 60 miles of water main. Since 1999, the funding for this program has come from low-interest financing from the New Jersey Environmental Infrastructure Trust program.
      In addition, solar power is helping us to address our energy needs. We believe in exploring alternative energy sources where these efforts make economic sense for the benefit of our customers. With the help of a grant from the New Jersey Board of Public Utilities Office of Clean Energy’s Renewable Energy Program, we installed a solar electric generation system at our primary water treatment plant in Edison, New Jersey. The system, which is a combination of fixed roof panels and a ground tracker system, is designed to produce approximately 4% of the power used at the plant annually.
Provide a Comprehensive Suite of Water and Wastewater Solutions in the Rapidly Developing Delaware Market that Results in Profitable Growth.
      Since 1992, we have increased our retail customer base in Delaware from approximately 3,000 to approximately 29,100 through acquisitions and customer growth. Our customer base in Delaware has the potential to continue substantial growth within the existing territories we currently serve. The developments we either serve or have entered into contracts to serve have obtained approvals to build additional housing units. If those additional housing units are built and sold, we project our customer base would grow to 41,000 without the acquisition of additional contracts. Any slowdown in construction of new residential development in Delaware will delay that growth. Further, there is significant economic development and population growth within and near many of our Delaware service areas. For example, according to the United States Census Bureau, from 2000 - 2005, the population in Kent and Sussex Counties is estimated to have increased 13.6% and 12.7%, respectively.
      Our strategy is to offer a suite of services to this expanding market relating to the design, building, operating and financing of water and wastewater systems, including systems inside and outside of our franchise areas and systems owned by others that we service under contracts. Our Tidewater and Southern Shores subsidiaries provide regulated water services.
      TESI, formed in 2005, is a regulated wastewater utility in Delaware. We intend to grow this business by obtaining additional franchises and constructing wastewater collection and treatment systems to meet the needs of developers, municipalities and commercial entities.
      White Marsh continues to seek to acquire contracts to operate non-regulated wastewater systems throughout Delaware. We believe our water and wastewater contract operations business provides us with additional tools to help grow our regulated water and wastewater businesses in Delaware.
Pursue Profitable, Core Growth in New Jersey.
      We expect core growth in New Jersey to come from water and wastewater management services as well as through service line protection services.
      We provide water and wastewater utility management services through our subsidiaries in New Jersey, including contract operations, maintenance and bulk water supply. We have significant operational expertise and are committed to working with municipalities, developers and industry to find solutions that meet their needs and to pursue opportunities for profitable growth.
      USA is actively marketing its LineCaresm service line protection program to customers throughout our service territories. We are also marketing LineCaresm to homeowners in local municipalities outside of our existing service areas.

Table of Contents

Invest in Products, Services and Other Viable Opportunities that Complement our Core Competencies.
      We have successfully grown through acquisitions in the past and will continue to seek such growth opportunities in the future. We intend to pursue acquisitions of municipally-owned and investor-owned water and wastewater systems and to engage in activities with respect to potential acquisitions, such as identifying suitable acquisition opportunities and attempting to negotiate mutually agreeable terms with acquisition candidates.
      Since January 1, 1999, USA-PA has operated and maintained the City of Perth Amboy’s water and wastewater systems. We continue to seek opportunities to enter into contracts with additional municipalities to operate their water and wastewater systems.
Recent Accounting Standard
      In September 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards (“SFAS”) No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans” (“SFAS 158”). SFAS 158 requires recognition of the overfunded or underfunded status of defined benefit pension and other postretirement plans as an asset or liability on the balance sheet and recognition of changes in that funded status in the year in which the changes occur through comprehensive income. 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. SFAS No. 87, “Employers’ Accounting for Pensions” (“SFAS 87”) and SFAS No. 106, “Employers’ Accounting for Postretirement Benefits Other Than Pensions” (“SFAS 106”) allowed for deferred recognition of this liability through amortization of this difference over time. Under SFAS 158, actuarial gains and losses and prior service costs and credits that arise during the period but, pursuant to SFAS 87 and SFAS 106 were not yet recognized as components of net periodic benefit cost, will be recognized as a component of Other Comprehensive Income (net of tax). SFAS 158 also requires 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 SFAS 106. Such amounts subsequently will not be amortized as a component of net periodic benefit cost. We will be required to adopt SFAS 158 as of December 31, 2006.
      Because we are subject to regulation in the states in which we operate, we are required to maintain our accounts in accordance with the regulatory authority’s rules and guidelines, which may differ from other authoritative accounting pronouncements. In those instances, we follow the guidance of SFAS No. 71, “Accounting for the Effects of Certain Types of Regulation” (“SFAS 71”). Based on prior regulatory practice, and in accordance with the guidance provided by SFAS 71, we will record approximately $13.5 million of underfunded pension and postretirement obligations, which otherwise would be recognized as Other Comprehensive Income as of December 31, 2006 under SFAS 158, as a Regulatory Asset, and recover those costs in our rates charged to customers. We do not anticipate that the adoption of this standard will have a material impact on our financial position, results of operations, and cash flows, except as described above.
Employees
      As of June 30, 2006, we had a total of 148 employees in New Jersey, and a total of 87 employees in Delaware. In addition, we lease 20 employees under the USA-PA contract with the City of Perth Amboy, New Jersey. No employees are represented by a union except the leased employees who are subject to a collective bargaining agreement with the City of Perth Amboy. We believe our employee relations are good. Wages and benefits, other than for leased employees, are reviewed annually and are considered competitive within both the industry and the regions where we operate.
Competition
      Our business in our franchised service area is substantially free from direct competition with other public utilities, municipalities and other entities. However, our ability to provide some contract water supply and wastewater services and operations and maintenance services is subject to competition from other public utilities, municipalities and other entities. Although Tidewater has been granted an exclusive franchise for

16


Table of Contents

each of its existing community water systems, its ability to expand service areas can be affected by the PSC awarding franchises to other regulated water utilities with whom we compete for such franchises.
Regulation
      We are regulated as to rates charged to customers for water and wastewater services in New Jersey and Delaware, as to the quality of the services we provide and as to certain other matters. Only our USA, USA-PA and White Marsh subsidiaries are not regulated utilities. We are subject to environmental and water quality regulation by the EPA, and the DEP with respect to operations in New Jersey and DNREC, the DPH, and the DRBC with respect to operations in Delaware. We are also subject to certain regulations regarding fire protection services in the areas we serve. In addition, our issuances of securities are subject to the prior approval of the SEC and the BPU or the PSC.
Regulation of Rates and Services
      New Jersey water and wastewater service operations (excluding the operations of USA-PA) are subject to regulation by the BPU. Similarly, our Delaware water and wastewater operations are subject to regulation by the PSC. These regulatory authorities have jurisdiction with respect to rates, service, accounting procedures, the issuance of securities and other matters of utility companies operating within the States of New Jersey and Delaware, respectively. For ratemaking purposes, we account separately for operations in New Jersey and Delaware to facilitate independent ratemaking by the BPU for New Jersey operations and the PSC for Delaware operations.
      In determining our rates, the BPU and the PSC consider the income, expenses, rate base of property used and useful in providing service to the public and a fair rate of return on that property each within its separate jurisdiction. Rate determinations by the BPU do not guarantee particular rates of return to us for our New Jersey operations nor do rate determinations by the PSC guarantee particular rates of return for our Delaware operations. Thus, we may not achieve the rates of return permitted by the BPU or the PSC.
Water Quality and Environmental Regulations
      Both the EPA and the DEP regulate our operations in New Jersey with respect to water supply, treatment and distribution systems and the quality of the water. The EPA, DNREC, DPH and DRBC regulate our operations in Delaware with respect to water supply, treatment and distribution systems and the quality of the water.
      Federal, New Jersey and Delaware regulations adopted relating to water quality require us to perform expanded types of testing to ensure that our water meets state and federal water quality requirements. In addition, environmental regulatory agencies are reviewing current regulations governing the limits of certain organic compounds found in the water as byproducts of treatment. We participate in industry-related research to identify the various types of technology that might reduce the level of organic, inorganic and synthetic compounds found in the water. The cost to water companies of complying with the proposed water quality standards depends in part on the limits set in the regulations and on the method selected to implement such reduction. We believe the CJO Plant capabilities put us in a strong position to meet any such future standards with regard to our Middlesex System. We regularly test our water to determine compliance with existing federal, New Jersey and Delaware primary water quality standards.
      Well water treatment in our Tidewater System is by chlorination and, in some cases, pH correction and filtration for nitrate and iron removal. Well water treatment in the Pinelands and Bayview Systems (chlorination only) is done at individual well sites.
      The DEP and the DPH monitor our activities and review the results of water quality tests that are performed for adherence to applicable regulations. Other regulations applicable to us include the Lead and Copper Rule, the maximum contaminant levels established for various volatile organic compounds, the Federal Surface Water Treatment Rule and the Total Coliform Rule.

Fire Protection Standards
      We are also subject to regulations related to fire protection services. In Delaware, fire protection is regulated by the Office of State Fire Marshal. In New Jersey there is no formal regulatory agency, but state regulations exist as to the size of piping required regarding the provision of fire protection services. Noncompliance with fire protection regulations and requirements could require capital expenditures by the Company to take corrective action.

DESCRIPTION OF CAPITAL STOCK
      Our authorized capital stock consists of 20,000,000 shares of common stock, without par value, 139,497 shares of Cumulative Preferred Stock, without par value, and 100,000 shares of Cumulative Preference Stock, without par value. As of October 4, 2006, there were 11,661,332 shares of common stock outstanding, four series of Cumulative Preferred Stock representing a total of 36,898 shares outstanding and no shares of the Cumulative Preference Stock outstanding. The issuance of the common stock offered hereby is subject to approval by the BPU.
      The transfer agent for the common stock is Registrar and Transfer Company. Our outstanding common stock is traded on The Nasdaq Global Select Market System.
      Certain New Jersey state laws and provisions in our Restated Certificate of Incorporation may deter or prevent a change in control of us and/or a change in management, even if desired by a majority of the shareholders.
      The following is a brief summary of certain information relating to our common stock, Preferred Stock and Preference Stock. This summary does not purport to be complete and is intended to outline such information in general terms only.
Dividend Rights
      Our Restated Certificate of Incorporation provides that whenever full dividends have been paid on the Preferred Stock and the Preference Stock outstanding for all past quarterly periods, the Board of Directors may declare and pay dividends on the common stock out of legally available funds.
      The dividend rate for our varying classes of Preferred Stock is as follows: $7.00 per share per annum for the $7.00 Series Cumulative Preferred Stock, $4.75 per share per annum for the $4.75 Series Cumulative Preferred Stock, $7.00 per share per annum for the $7.00 Cumulative and Convertible Preferred Stock, and $8.00 per share per annum for the $8.00 Series Cumulative and Convertible Preferred Stock.
Voting Rights
      Every holder of the common stock is entitled to one vote for each share held of record. Our Restated Certificate of Incorporation and By-laws provide for a Board of Directors divided into three classes of directors serving staggered three-year terms. A classified board has the effect of increasing the time required to effect a change in control of the Board of Directors. Our By-laws provide that nominations for directors must be (i) made in writing, (ii) received by the Secretary of the Company not less than 21 days prior to the date fixed for the meeting of shareholders and (iii) accompanied by the written consent of the nominee to serve as a director. In addition, the Restated Certificate of Incorporation provides that the By-laws may only be amended by shareholders if the holders of two-thirds or more of the issued and outstanding shares of common stock vote for the amendment. Our Restated Certificate of Incorporation also provides that shareholders may take action only at an annual or special meeting upon prior notice and pursuant to a vote.
      No holder of Preferred Stock or Preference Stock (none of which Preference Stock has been issued) has any right to vote for the election of directors or, except as otherwise required by law, for any other purpose; provided, however, that if and whenever dividends on the outstanding Preferred Stock are in arrears in an amount equal to at least four quarterly dividends, the holders of the outstanding Preferred Stock of all series, voting as a class, are entitled, until all dividends in arrears are paid, to elect two members to the Board of Directors, which two members shall be in addition to the directors elected by the holders of the common stock. Whenever dividends on the outstanding Preference Stock are in arrears in an amount equal to at least four quarterly dividends, the holders of the outstanding Preference Stock of all series, voting as a class, are entitled, until all dividends in arrears are paid, to elect two members to the Board of Directors, which two members shall be in addition to the members elected by the holders of the common stock and by the holders of the Preferred Stock. In addition, unless certain tests set forth in our charter are met, the consent of the holders of a majority of the outstanding shares of Preferred Stock of all series, voting as a class, is required for issuance or sale of any additional series of Preferred Stock or any class of stock ranking prior to or on a parity

21


Table of Contents

with the Preferred Stock as to dividends or distributions. The consent of the holders of two-thirds in interest of the outstanding Preferred Stock of all series, voting as a class, is required to create or authorize any stock ranking prior to the Preference Stock as to dividends or in liquidation, or to create or authorize any obligation or security convertible into shares of any such stock, except that such consent is not required with respect to any increase in the number of shares of Preferred Stock which we are authorized to issue or with respect to the creation and establishment of any series of our Preferred Stock.
Convertibility
      The conversion feature of the no par $7.00 Series Cumulative and Convertible Preferred Stock allows the holders of such shares of preferred stock to exchange one convertible preferred share for twelve shares of our common stock. In addition, we may redeem up to 10% of the outstanding convertible stock in any calendar year at a price equal to the fair market value of twelve shares of our common stock for each share of convertible stock redeemed.
      The conversion feature of the no par $8.00 Series Cumulative and Convertible Preferred Stock allows the holders of such shares to exchange one convertible preferred share for 13.714 shares of our common stock. The preferred shares were convertible at the election of the security holder until 2004. Since that time, both we and the holders of the $8.00 Series Cumulative and Convertible Preferred Stock have the right to convert the shares of preferred stock into our common stock.
Liquidation Rights
      Holders of common stock are entitled to share on a pro-rata basis, subject to the rights of holders of our First Mortgage Bonds, Preferred Stock or Preference Stock, in our assets legally available for distribution to shareholders in the event of our liquidation, dissolution or winding up.
Restriction on Acquisitions
      As a New Jersey corporation with its headquarters and principal operations in the state, we are a “resident domestic corporation” as defined in New Jersey’s Shareholder Protection Act (the “Act”). The Act bars any “business combination” as defined in that Act (generally, a merger or other acquisition transaction) with any person or affiliate of a person who owns 10% or more of the outstanding voting stock of a resident domestic corporation for a period of five years after such person first owns 10% or more of such stock, unless the “business combination” both is approved by the board of directors of the resident domestic corporation prior to the time that person acquires 10% or more of the resident domestic corporation’s voting stock and meets certain other statutory criteria.

DIVIDEND REINVESTMENT PLAN
      We have a Dividend Reinvestment and Common Stock Purchase Plan (“DRP”) under which participating shareholders may have cash dividends on all or a portion of their shares of common stock or Cumulative Preferred Stock automatically reinvested in newly issued shares of common stock and may invest at the same time up to an additional $25,000 per quarter in newly issued shares of common stock. Under the DRP, we may permit the purchase of shares of common stock at ninety-five percent (95%) of market value for specified periods as announced by us from time to time. We last authorized the purchase of shares of common stock at ninety-five percent (95%) of market value during the period of June 1, 2005 to December 1, 2005. As currently in effect, any purchase of shares under the DRP is at full market value. No commission or service charge is paid by participants in connection with any of their purchases under the DRP. The number of shares authorized under the DRP is 1,700,000 shares. The cumulative amount of shares issued under the DRP as of October 4, 2006 is 1,567,249.

Edwards & Sons, Inc. are serving as the representatives (the “Representatives”), have severally agreed to purchase, and we have agreed to sell to the underwriters, the aggregate number of shares of common stock set forth opposite their respective names below at the public offering price less the underwriting discount on the cover page of this prospectus.

      The underwriting agreement provides that obligations of the underwriters to purchase the shares and accept the delivery of the common stock that are being offered are subject to certain conditions precedent including the absence of any materially adverse change in our business, the receipt of certain certificates, opinions and letters from us, our attorneys and independent auditors. The offering is being made on a firm commitment basis and, thus, each underwriter is obligated to purchase all of the shares of the common stock being offered by this prospectus (other than shares of common stock covered by the over-allotment option described below) if it purchases any of the shares of common stock.
      The underwriters propose to offer some of the shares of common stock to the public initially at the offering price per share shown on the cover page of this prospectus and may offer shares to certain dealers at such price less a concession not in excess of $          per share. The underwriters may allow, and such dealers may reallow, a concession not in excess of $          per share to certain other dealers. After the public offering of the common stock, the public offering price and the concessions may be changed by the underwriters.
      The offering of common stock is made for delivery when, as and if accepted by the underwriters and subject to prior sale and to withdrawal, cancellation or modification of the offer without notice. The underwriters reserve the right to reject any order for the purchase of common stock in whole or in part.
      The following table shows the per share and total underwriting discount to be paid to the underwriters by us. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase the over-allotment shares:
                                 
    Per Share   Total
         
    Without   With   Without   With

Underwriter Discounts and Commissions to be paid by us
  $       $       $       $    
      We estimate that our out-of-pocket expenses for this offering will be approximately $245,000. We have also agreed to pay the underwriters a non-accountable expense allowance of $50,000.
      We have granted to the underwriters an option, exercisable for up to 30 days after the date of this prospectus, to purchase up to 195,000 additional shares of common stock, at the same price per share as the public offering price, less the underwriting discounts and commissions shown on the cover page of this prospectus. The underwriters may exercise such option only to cover over-allotments in the sale of the shares of common stock offered by this prospectus. To the extent the underwriters exercise this option, each of the underwriters has a firm commitment, subject to certain conditions, to purchase a number of the additional shares of common stock proportionate to such underwriter’s initial commitment as indicated in the table above that lists the underwriters.
      In connection with this offering and in compliance with applicable securities laws, the underwriters may over-allot (i.e., sell more shares of common stock than is shown on the cover page of this prospectus) and may effect transactions that stabilize, maintain or otherwise affect the market price of the common stock at levels

above those which might otherwise prevail in the open market. Such transactions may include placing bids for the common stock or effecting purchases of the common stock for the purpose of pegging, fixing or maintaining the price of the common stock or for the purpose of reducing a short position created in connection with the offering. The underwriters are not required to engage in any of these activities and any such activities, if commenced, may be discontinued at any time.
      In connection with this offering, the underwriters may make short sales of our shares of common stock and may purchase those shares on the open market to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriter’s over-allotment option to purchase additional shares in the offering. The underwriters may close out any covered short position by either exercising their over-allotment option or purchasing shares on the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase on the open market as compared to the price at which they may purchase shares through the over-allotment option. “Naked” short sales are sales in excess of the over-allotment option. The underwriters may close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward price pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering. Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of the our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market.
      The underwriters may also impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the shares of the common stock originally sold by that syndicate member are purchased in a stabilizing transaction or syndicate covering transaction to cover syndicate short positions. The imposition of a penalty bid may have an effect on the price of the common stock to the extent that it may discourage resales of the common stock.
      In connection with this offering, the underwriters, selling group members or their respective affiliates who are qualified market makers on The Nasdaq Global Select Market may engage in passive market making transactions in our common stock on The Nasdaq Global Select Market in accordance with Rule 103 of Regulation M under the Securities Exchange Act of 1934, as amended, during the five business days prior to the pricing of the offering before the commencement of offers and sales of the common stock. Passive market makers must comply with applicable volume and price limitations and must be identified as such. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security. If all independent bids are lowered below the passive market maker’s bid, however, such bid must then be lowered when certain purchase limits are exceeded.
      We and the underwriters make no representation or prediction as to the direction or magnitude of any effect that these transactions may have on the price of the common stock. In addition, we and the underwriters make no representation that the underwriters will engage in such transactions or that such transactions, once commenced, will not be discontinued without notice.
      Each underwriter does not intend to confirm sales of the common stock to any accounts over which it exercises discretionary authority.
      Our directors, executive officers and certain of our other shareholders have agreed that they will not, without the Representatives’ prior written consent for a period of 90 days after the effective date of the Registration Statement, sell, offer to sell, contract to sell, or otherwise dispose of, directly or indirectly, any shares of common stock of the Company or any securities convertible into, or exercisable or exchangeable for, common stock of the Company (other than shares issuable pursuant to a plan for employees in effect on the date of this prospectus).

Item 15. Indemnification of Directors and Officers
      Section 14A:3-5 of the New Jersey Business Corporation Act (the “NJBCA”) gives the Company power to indemnify each of its directors and officers against expenses and liabilities in connection with any proceeding involving him by reason of his being or having been a director or officer if (a) he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Company, and (b) with respect to any criminal proceeding, he had no reasonable cause to believe his conduct was unlawful. However, in a proceeding by or in the right of the Company, there shall be no indemnification in respect of any liabilities or expenses if the officer or director shall have been adjudged liable to the Company unless the Court in such proceeding determines he is entitled to indemnity for such liabilities and/or expenses. No indemnification shall be made to or on behalf of a director or officer if a judgment or other final adjudication adverse to such director or officer establishes that his acts or omissions (a) were in breach of his duty of loyalty to the Company and its shareholders, (b) were not in good faith or involved a knowing violation of law or (c) resulted in receipt by the director or officer of an improper personal benefit. The NJBCA defines an act or omission in breach of a person’s duty of loyalty as an act or omission which that person knows or believes to be contrary to the best interests of the Corporation or its shareholders in connection with a matter in which he has a material conflict of interest. If a director or officer is successful in a proceeding, the statute mandates that the Company indemnify him against expenses.
      Article V of the Company’s By-laws provides:
        “Any present or future director or officer of the Company and any present or future director or officer of any other corporation serving as such at the request of the Company because of the Company’s interest in such other corporation, or the legal representative of any such director or officer, shall be indemnified by the Company against reasonable costs, expenses (exclusive of any amount paid to the Company in settlement), and counsel fees paid or incurred in connection with any action, suit, or proceeding to which any such director or officer or his legal representative may be made a party by reason of his being or having been such director or officer, provided, (1) said action, suit, or proceeding shall be prosecuted against such director or officer or against his legal representative to final determination, and it shall not be finally adjudged in said action, suit, or proceeding that he had been derelict in the performance of his duties as such director or officer, or (2) said action, suit or proceeding shall be settled or otherwise terminated as against such director or officer or his legal representative without a final determination on the merits, and it shall be determined by the Board of Directors (or, at the option of the

II-1


Table of Contents

  Board of Directors, by a disinterested person or persons selected by the Board of Directors to determine the matter) that said director or officer had not in any substantial way been derelict in the performance of his duties as charged in such action, suit, or proceeding. The right of indemnification provided by this By-law shall be in addition to and not in restriction or limitation of any other privilege or power which the Company may have with respect to the indemnification or reimbursement of directors, officers, or employees.”
      The Company has in effect a $20,000,000.00 policy of insurance indemnifying it against certain liabilities to directors and officers of the Company, and indemnifying directors and officers of the Company against certain of the liabilities which they may incur in acting in their capacities as such, all within specific limits.

Item 17. Undertakings
      Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the “1933 Act”), may be available to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that, in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the 1933 Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer, or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the 1933 Act and will be governed by the final adjudication of such issue.
      The undersigned Registrant hereby undertakes that:
        (1) For purposes of determining any liability under the 1933 Act, the information omitted from the form of prospectus filed as part of a registration statement in reliance upon Rule 430A and contained in the form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the 1933 Act shall be deemed to be part of the registration statement as of the time it was declared effective.
 
        (2) For the purposes of determining any liability under the 1933 Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
        (3) For purposes of determining any liability under the 1933 Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
