REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To the Administrative Committee of the NUI Corporation Savings and Investment Plan: We have audited the accompanying statement of net assets available for benefits, including the schedule of investments, of the NUI Corporation Savings and Investment Plan (the "Plan") as of December 31, 1998 and 1997, and the related statements of changes in net assets available for benefits for each of the two years in the period ended December 31, 1998. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 1998 and 1997, and the changes in net assets available for benefits for the year ended December 31, 1998, in conformity with generally accepted accounting principles. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of assets held for investment purposes and reportable transactions are presented for purposes of additional analysis and are not a required part of the basic financial statements but are supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The Fund Information in the statement of changes in net assets available for benefits is presented for purposes of additional analysis rather than to present the changes in net assets available for plan benefits of each fund. The supplemental schedules and Fund Information have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.

NUI CORPORATION SAVINGS AND INVESTMENT PLAN NOTES TO FINANCIAL STATEMENTS FOR THE YEARS ENDED DECEMBER 31, 1998 and 1997 1. Summary Description of the Plan The NUI Corporation Savings and Investment Plan (the Plan) is a defined contribution plan covering eligible employees of NUI Corporation and its subsidiaries (the Company). The Plan, as amended, conforms to the requirements of the Employee Retirement Income Security Act of 1974, as amended. The following description provides only general information. See the Plan agreement for a more complete description. See Note 5 for a discussion of Plan amendments. The Plan allows eligible employees who participate to make "basic" contributions of up to 6% of their annual base pay, which are matched by contributions by the Company. Participants investing in the NUI Stock Fund are matched by the Company at 60% of their "basic" contributions. "Basic" contributions invested in all other funds are matched by the Company at 50%. The matching percentage cannot be less than 25%. Participants may make additional contributions of up to 10% of their annual base pay, providing these contributions do not exceed limits imposed by the Internal Revenue Code of 1986, as amended (the Code). These additional contributions are not matched by the Company. Contributions may be made on a before-tax or after-tax basis as permitted by tax regulations. Company contributions are invested in the NUI Stock Fund, unless the participant has reached age 55, whereby they can direct the investment of these contributions into any fund. Participant contributions may be invested in the following funds: Income Accumulation Fund, Asset Allocation Fund, Norwest Large Company Growth A Fund, S&P 500 Stock Fund, the LifePath Funds, Templeton Foreign Fund and the NUI Stock Fund, as designated by the participants. A Plan participant is vested at all times in the amount of his/her contributions and earnings thereon. A participant becomes 50% vested in the Company contributions after 36 months of service, 75% after 48 months of service and 100% after 60 months of service. An eligible employee with five or more years of service with the Company becomes fully vested upon entering the Plan. A participant also becomes fully vested upon attaining his/her normal retirement date as an employee, or upon his/her death or disability. Forfeitures of a participant's non-vested account balances can be used to pay Plan fees and/or reduce Company contributions, as directed by the Plan Administrator. Forfeitures during the years ended December 31, 1998 and 1997 were $6,000 and $10,134, respectively. Participants may borrow up to 50% of the value of the vested portion of their accounts, excluding the Company match portion of their accounts, as calculated on the effective date of the loan, up to a maximum of $50,000. The interest rate is the prime rate plus 1% at the time of the loan. The term of the loan cannot exceed five years, nor be less than one year. If a participant's employment is terminated for any reason, the remaining unpaid loan balance becomes immediately due and payable, and if unpaid, may become a taxable distribution. Loan repayments are credited to a participant's account based upon the participant's investment election for new contributions. Although it has not expressed any intent to do so, the Company has the right under the Plan agreement to terminate the Plan. Upon termination, all employees would become 100% vested and benefits would be distributed to participants. In 1988, certain NUI subsidiaries participating in the Plan were spun off to shareholders as KCS Energy, Inc. (KCS). For each share of NUI common stock outstanding, one share of KCS common stock was issued. KCS participants held approximately 15.9% of Plan assets as of June 1, 1988, the effective date of the spin-off. As a result of the spin-off, KCS participants, through the KCS Stock Fund, can maintain their balances in the Plan as of the date of spin-off; however, they cannot make further contributions to the Plan and may withdraw their balances in accordance with the withdrawal provisions of the Plan. 2. Significant Accounting Policies The financial statements have been prepared on the accrual basis of accounting. The Company's management has made a number of estimates and assumptions relating to the reporting of investments. Actual results could differ from those estimates. The Plan's investments in each Investment Fund are maintained in shares/units and are reflected in the accompanying Statement of Net Assets Available for Benefits at market value. The market value of the Insured Money Market and loans to participants is based on cost, which approximates market value. The market value of the Income Accumulation Fund is determined in good faith and in the best judgment of the investment officers of Merrill Lynch Trust Company (Merrill Lynch) in accordance with accepted practices, applicable laws and regulations, and procedures formulated by Merrill Lynch. The market value of the Asset Allocation, Norwest Large Company Growth A, LifePath Funds, Templeton Foreign Fund, and S&P 500 Stock Funds is based on the Funds' published quotation. The market value of the KCS and NUI Stock Funds is based on published market quotations of the Funds' underlying assets. Purchases and sales of assets are reflected on a trade-date basis. The value of a share/unit is determined daily by dividing the value of each Investment Fund by its total number of outstanding shares/units. The following is a summary of the share/unit values and shares/units outstanding as of December 31, 1998 and 1997: 1998 1997 ------------------------ ------------------------ Share/Unit Shares/Units Share/Unit Shares/Units Value Outstanding Value Outstanding Income Accumulation Fund $14.81 593,151 $13.95 652,608 Asset Allocation Fund $14.14 74,835 $12.74 438,406 Growth Stock Fund - - $14.61 245,745 Norwest Large Company Growth A Fund $54.48 63,256 - - S&P 500 Stock Fund $24.61 302,385 $20.39 292,720 KCS Stock Fund $2.40 510,651 $15.62 569,788 NUI Stock Fund $13.01 1,582,784 $13.41 1,706,493 LifePath 2000 $11.63 7,076 $11.27 2,226 LifePath 2010 $14.40 29,831 $13.30 13,827 LifePath 2020 $16.47 8,650 $14.82 12,603 LifePath 2030 $18.73 5,180 $16.23 6,599 LifePath 2040 $20.33 6,523 $17.31 3,385 Templeton Foreign Fund $8.39 32,124 $ 9.95 28,415 In accordance with generally accepted accounting principles, distributions are recorded when paid. There were no distributions payable to participants at December 31, 1998 and 1997. Recordkeeping, investment fund election changes and loan fees are paid by the participants from their accounts. Investment management fees are also paid by the participants and are included as a reduction of the investment return. All other fees of the Plan (e.g. legal, accounting, tax, etc.) are paid by the Company. Plan assets are invested in various mutual funds, any of which could from time-to-time utilize financial derivatives. Generally accepted accounting principles require the investment managers of such funds to list in their financial statements the amount and purpose of such derivatives. Upon request, participants can be provided with copies of the funds' financial statements directly from Merrill Lynch and should refer to these for information on this issue. Derivative securities are not used for speculative purposes. When derivatives are used, it is simply to manage a fund into a market-neutral position, to attempt to match the return of a stated benchmark. 3. Investment Funds The Plan consists of the following funds: Income Accumulation Fund - This fund seeks to provide a stable return while preserving value by investing in U.S. government and agency securities, and other short-term fixed-income securities. Asset Allocation Fund - This fund seeks to achieve a high level of long-term total return at reasonable risk by shifting investments among three asset classes: common stocks, U.S. Treasury long-term bonds and money market instruments. Norwest Large Company Growth A Fund _ This fund seeks long-term capital appreciation by investing in larger capitalization growth companies whose growth rates in earnings and revenues are expected to be above average. S&P 500 Fund - This fund seeks to achieve a long-term total rate of return approximating the total rate of return of the stocks comprising the S&P 500 index. KCS Stock Fund - This fund is no longer designated as available for investment by participants. Existing investments and earnings thereon may continue to be invested in the KCS Stock Fund until withdrawn or transferred to another fund in the Plan. NUI Stock Fund - This fund is invested and dividends are reinvested in common stock of NUI Corporation. Templeton Foreign Fund - This is an international equity fund that seeks long-term capital growth. Principal investments are in stocks and debt obligations of companies and governments outside the United States. LifePath Funds - These are asset allocation funds that change their investment mix based on the expected risk and return of the different asset classes in which they invest. LifePath represents a family of five funds with each fund name containing a target date; the nearer the target date the more conservatively the fund invests. The objective of each fund is to maximize return while maintaining a level of risk appropriate to its target date. The Plan also uses an Insured Money Market Fund as a pass-through of amounts in and out of the Investment Funds. This fund had a balance of $63,494 as of December 31, 1998. Interest and other income earned by the Investment Funds are reinvested by the Trustee in accordance with the terms of the Plan. Interest and other income earned by the Investment Funds are reinvested by the Trustee in accordance with the terms of the Plan. 4. Federal Income Taxes The Internal Revenue Service issued a determination letter, dated July 22, 1995, which stated that the Plan, as designed, met the requirements of Section 401 (a) of the Internal Revenue Code and was exempt from taxation. Management and Counsel believe the Plan continues to operate in accordance with IRS regulations and therefore continues to be tax exempt. Under present Federal income tax law, a participant is not taxed currently on any before-tax contributions or Company contributions to the Plan, income earned by the Plan, or gain on the sale of securities held by the Plan until the participant's account is distributed to him/her or made available to him/her without restriction. Participants are taxed currently on the amount of their after-tax contributions.
