NEW JERSEY NATURAL GAS COMPANY

General

  NJNG provides natural gas service to more than 385,000 customers. Its service
territory encompasses 1,436 square miles, covering 104 municipalities with an
estimated population of 1.3 million.

  NJNG's service territory is primarily suburban, with a wide range of cultural
and recreational activities, highlighted by approximately 100 miles of New
Jersey seacoast. It is in proximity to New York, Philadelphia and the
metropolitan areas of northern New Jersey and is accessible through a network of
major roadways and mass transportation. These factors have contributed to NJNG
adding 11,819, 11,708 and 10,978 new customers in 1998, 1997 and 1996,
respectively. This annual growth rate of 3% is expected to continue with
projected additions of 36,000 new customers over the next three years. See
Management's Discussion and Analysis of Financial Condition and Results of
Operations (MD&A) - Liquidity and Capital Resources-NJNG in the Company's 1998
Annual Report for a discussion of NJNG's projected capital expenditure program
associated with this growth in 1999 and 2000.

  In assessing the potential for future growth in its service area, NJNG uses
information derived from county and municipal planning boards which describes
housing developments in various stages of approval. In addition, builders in
NJNG's service area are surveyed to determine their development plans for future
time periods. Finally, NJNG uses information concerning its service territory
and projected population growth rates from a periodic study prepared by outside
consultants. In addition to customer growth through new construction, NJNG's
business strategy includes aggressively pursuing conversions from other fuels,
such as electricity and oil. It is estimated that approximately 40% of NJNG's
projected customer growth will consist of conversions. NJNG will also continue
to pursue off-system sales and non-peak sales, such as natural gas-fueled
electric generating projects.

Throughput

  For the fiscal year ended September 30, 1998, operating revenues and
throughput by customer class were as follows:

  See MD&A - NJNG Operations in the Company's 1998 Annual Report for a
discussion of gas and transportation sales. Also see NJNG Operating Statistics
in the Company's 1998 Annual Report for information on operating revenues and
throughput for the past six years. During this period, no single customer
represented more than 10% of operating revenues.

Seasonality of Gas Revenues

  As a result of the heat-sensitive nature of NJNG's residential customer base,
therm sales are significantly affected by weather conditions. Specifically,
customer demand substantially increases during the winter months when natural
gas is used for heating purposes. See MD&A - Liquidity and Capital Resources -
NJNG in the Company's 1998 Annual Report for a discussion of the effect of
seasonality on cash flow.

  The impact of weather on the level and timing of NJNG's revenues and cash
flows has been affected by a weather-normalization clause (WNC), which provides
for a revenue adjustment if the weather varies by more than one-half of 1% from
normal, or 20-year average, weather. The WNC does not fully protect the Company
from factors such as unusually warm weather and declines in customer usage
patterns, which were set at the conclusion of NJNG's last base rate case in
January 1994. The accumulated adjustment from one heating season (i.e.,
October-May) is billed or credited to customers in subsequent periods. See MD&A
- - NJNG Operations in the Company's 1998 Annual Report and Item 1. Business -
State Regulation and Rates for additional information with regard to the WNC.

Gas Supply

A) Firm Natural Gas Supplies

  NJNG currently purchases a diverse gas supply portfolio consisting of
long-term (over seven months), winter-term (for the five winter months) and
short-term contracts. In 1998, NJNG purchased gas from 76 suppliers under
contracts ranging from one month to twelve years. NJNG has 5 long-term firm gas
purchase contracts and purchased approximately 12% of its gas in 1998 under one
long-term firm gas purchase contract with Alberta Northeast Gas Limited, which
expires in 2006. NJNG does not purchase more than 10% of its total gas supplies
under any other single long-term firm gas purchase contract. NJNG believes that
its supply strategy should adequately meet its expected firm load over the next
several years.

B) Firm Transportation and Storage Capacity

  In order to deliver the above supplies, NJNG maintains agreements for firm
transportation and storage capacity with several interstate pipeline companies.
The pipeline companies that provide firm transportation service to NJNG's city
gate stations in New Jersey, the maximum daily deliverability of that capacity
and the contract expiration dates are as follows:

  The pipeline  companies  that provide firm  transportation  service to NJNG,
which feeds the above pipelines are: Texas Gas Transmission  Corporation,  CNG
Transmission Corporation,  Columbia Gulf Transmission Corporation,  Equitrans,
Inc. and Carnegie Interstate Pipeline Company.

  In addition, NJNG has storage and related transportation contracts that
provide additional maximum daily deliverability of 216,000 Dths from storage
fields in its Northeast market area. The significant storage suppliers, the
maximum daily deliverability of that storage capacity and the contract
expiration dates are as follows:

                                                =======
</TABLE>

  NJNG also has storage contracts with CNG Transmission Corporation (maximum
daily deliverability of 103,661 Dths) and Equitrans, Inc. (maximum daily
deliverability of 9,996 Dths), but utilizes NJNG's existing transportation
contracts to transport that gas from the storage fields to its city gate.

C) Peaking Supply

  To meet its increased winter peak day demand, NJNG, in addition to utilizing
the previously mentioned firm storage services, maintains two liquefied natural
gas (LNG) facilities and purchases firm storage services. See Item 2 -
Properties - NJNG for additional information regarding the LNG storage
facilities. NJNG presently has LNG storage deliverability of 140,000 Dths per
day, which represents approximately 22% of its peak day sendout.

D)  Future Supplies

   NJNG expects to be able to meet the current level of gas requirements of its
existing and projected firm customers for the foreseeable future. Nonetheless,
NJNG's ability to provide supply for its present and projected sales will depend
upon its suppliers' ability to obtain and deliver additional supplies of natural
gas, as well as NJNG's ability to acquire supplies directly from new sources.
Factors beyond the control of NJNG, its suppliers and the independent suppliers
who have obligations to provide gas to certain NJNG customers, may affect NJNG's
ability to deliver such supplies. These factors include other parties control
over the drilling of new wells and the facilities to transport gas to NJNG's
city gate, competition for the acquisition of gas, priority allocations, the
regulatory and pricing policies of federal and state regulatory agencies, as
well as the availability of Canadian reserves for export to the United States.
Proposed energy deregulation legislation discussed immediately below may 
increase

                                       4
<PAGE>   7
competition among gas utilities and impact the quantities of natural gas
requirements needed for residential services. If NJNG's gas requirements
decrease, NJNG expects to resell any unnecessary supplies that it is required to
purchase under existing agreements with its suppliers.

Energy Deregulation Legislation

  Committees of the New Jersey Senate and Assembly have completed a series of
hearings focusing on the "Electric Discount and Energy Restructuring Act." Bills
S-5/A-10 were introduced in October 1998 after nearly a year of stakeholder
meetings conducted by the New Jersey Board of Public Utilities (BPU). The
pending legislation includes various provisions relating to natural gas
utilities. These provisions provide all customer classes with the ability to
choose their natural gas supplier other then their incumbent utility by December
31, 1999. The bills also allow continuation of the utilities role as a gas
supplier at least until December 31, 2002, when the BPU must decide whether to
make the gas supply function competitive. The proposed legislation would allow
natural gas utilities to stay in competitive services (i.e., appliance
services), and customers would be allowed to choose their provider of account
services (i.e., meter reading, billing and collections) by December 31, 2000.

  The legislature is currently expected to vote on this matter in early calendar
1999.

Regulation and Rates

A)  State

  NJNG is subject to the jurisdiction of the BPU with respect to a wide range of
matters, such as rates, the issuance of securities, the adequacy of service, the
manner of keeping its accounts and records, the sufficiency of gas supply,
pipeline safety and the sale or encumbrance of its properties.

  Over the last five years, NJNG has been granted two increases in its base
tariff rates, and various increases and decreases in its Levelized Gas
Adjustment clause (LGA). The latter of the base rate increases related to the
recognition of costs for postretirement benefits other than pensions (OPEB).
Through its LGA billing factor, which is reviewed annually, NJNG recovers the
cost of six adjustment clauses. They are: (i) the Gas Cost Recovery (GCR)
factor, which reflects purchased gas costs that are in excess of the level
included in its base rates, (ii) Prior Gas Cost Adjustment Surcharge (PGCA)
factor, which is designed to recover $34.9 million of unrecovered gas costs from
September 1997 and earlier, (iii) Demand Side Management (DSM) factor for
recovery of conservation-related costs, (iv) Remediation Adjustment (RA) factor,
which recovers the costs of remediating former manufactured gas plant sites, (v)
Transportation Education and Implementation (TEI) factor for recovery of
incremental costs incurred in administering a transportation program and (vi)
the WNC factor, which credits or surcharges margins accrued from the past
heating season weather. LGA recoveries do not include an element of profit and,
therefore, have no effect on earnings.

   See Note 7 to the Consolidated Financial Statements - Regulatory Issues in
the Company's 1998 Annual Report for additional information regarding NJNG's
rate proceedings.

  In September 1991, the BPU adopted a conservation incentive rule which
requires energy utilities to file a DSM plan. In June 1995, the BPU approved a
Stipulation Agreement approving NJNG's DSM plan. In November 1997, the BPU
extended NJNG's DSM plan to January 1999. In November 1998, NJNG requested the
DSM plan be extended to July 2000.

  In November 1992, NJNG filed a petition with the BPU for approval of a Gas
Service Agreement (GSA) executed between NJNG and Freehold Cogeneration
Associates L.P. (Freehold) in September 1992. The GSA provided for NJNG to
supply Freehold with between 21,800 and 26,000 Dths of natural gas per day over
a twenty-year period. Freehold had planned to construct and operate a
cogeneration facility in Freehold, New Jersey, and had executed a power purchase
agreement with Jersey Central Power & Light Company (JCP&L). In November 1993,
the BPU ruled that Freehold and JCP&L should attempt to renegotiate the power
purchase agreement within 30 days of receipt of a written order. In February
1994, the BPU approved the GSA conditioned by a side letter agreement in which
Freehold and NJNG agreed to negotiate in good faith to amend the pricing terms
of the GSA to conform it to changes, if any, in the power purchase agreement if
it is renegotiated. The November 1993 BPU order was overturned in litigation not
involving NJNG as a party. Freehold was successful in this litigation. In April
1996, JCP&L and Freehold reached an agreement in which JCP&L bought out its
rights and obligations under the power purchase agreement for $120 million ("Buy
Out Agreement"). Under the Buy Out Agreement, JCP&L indemnified Freehold against
certain potential claims, including any potential claims NJNG may have
against Freehold for breach of the GSA. NJNG currently is in discussions with
JCP&L and the BPU regarding a possible resolution of NJNG's potential claims.

  In January 1998, the BPU approved a 3.5% LGA price increase, which included
updates to NJNG's GCR, PGCA, WNC, RA and DSM clause factors.

  In September 1998, the BPU approved a comprehensive agreement which provides
all NJNG customers the option to choose a natural gas supplier as early as
January 1, 1999, modification and extension of the existing margin-sharing
formulas for the off-system and capacity release programs and

                                       6
<PAGE>   9
a new margin-sharing incentive related to permanent cost reductions of NJNG's
gas supply portfolio. The BPU also approved an additional 3.5% price increase
designed to recover $34.9 million of deferred gas costs from both sales and
transportation customers. All of these provisions are effective for the period
from October 1, 1998 to December 31, 2001.

  In September 1998, NJNG filed with the BPU to extend the current $.1842 per
therm LGA billing factor for a 15-month term rather than for 12 months. By using
the 15-month LGA billing factor, the Company would move to a calendar year basis
for LGA recovery. Further, NJNG proposed a flexible LGA pricing mechanism to
transition toward market-based pricing. The 15-month proposal is currently being
discussed by the parties to the proceeding. NJNG also requested the collection
of $15.8 million of WNC margins accrued but not collected due to the impact of
warmer-than-normal weather during fiscal year 1998 and minimal adjustments to
its RA, DSMAC and Transportation Education and Implementation charge (TEI)
factors.

  See Item 3.c Legal Proceedings - BPU Inquiry for information on potential
regulatory proceedings.

B)  Federal

  NJNG is subject to regulation by the Federal Energy Regulatory Commission
(FERC). Since the mid-1980's, the FERC has issued a series of orders,
regulations and policy statements (e.g., FERC Orders 380, 436, 451, 500, and
528) intended to transform the natural gas industry from a highly regulated
industry to a less regulated, market-oriented industry. The culmination of the
FERC's deregulatory effort was the issuance of Order 636 which established new
rules mandating the unbundling of interstate pipeline sales for resale and
transportation services. The FERC instituted proceedings through which NJNG's
interstate pipeline suppliers have restructured their services in response to
Order 636.

  The transition to a more market-oriented interstate pipeline market may offer
long-term benefits. Order 636 has provided NJNG with increased opportunities to
purchase and manage its own, specifically-tailored gas supply portfolio and to
resell its interstate pipeline capacity to other potential customers during
off-peak periods. However, these long-term benefits have been offset by
increases in interstate pipeline demand charges required by Order 636, in
addition to the flow-through of transition costs that pipeline companies have
incurred as a result of the restructuring of their existing gas purchase and
sales arrangements. In the individual pipeline restructuring proceedings
resulting from Order 636, all of NJNG's pipeline suppliers have settled
transition cost recovery issues with their customers. These settlements provide
for partial cost absorption by some of NJNG's pipeline suppliers and the orderly
recovery of remaining costs from pipeline customers, including NJNG.

  NJNG continually reviews its gas supply portfolio requirements in the
post-Order 636 environment. Because of its interconnections with multiple
interstate pipelines, NJNG believes that the Order 636 proceedings will not have
a material impact on its ability to obtain adequate gas supplies at market
rates. However, no assurance can be given in this regard.


Franchises

  NJNG holds non-exclusive franchises granted by the 104 municipalities it
serves which gives it the right to lay, maintain and operate public utility
property in order to provide natural gas service within

                                       7
<PAGE>   10
these municipalities. Of these franchises, 47 are perpetual and the balance
expire between 1999 and 2038.

Competition

  Although its franchises are non-exclusive, NJNG is not currently subject to
competition from other natural gas distribution utilities with regard to the
transportation of natural gas in its service territory. Due to significant
distances between NJNG's current large industrial customers and the nearest
interstate natural gas pipelines, as well as the availability of its
transportation tariff, NJNG currently does not believe it has significant
exposure to the risk that its distribution system will be bypassed. Competition
does exist from suppliers of oil, coal, electricity and propane. At the present
time, natural gas enjoys an advantage over alternate fuels as the preferred
choice of fuels in over 95% of new construction due to its efficiency and
reliability. As deregulation of the natural gas industry continues, prices will
be determined by market supply and demand, and while NJNG believes natural gas
will remain competitive with alternate fuels, no assurance can be given in this
regard.

  In October 1994, the BPU approved a Stipulation Agreement that provides NJNG's
commercial and industrial customers an expanded menu of transportation and
supplier choices. As a result of the BPU approval, NJNG's sales to its
commercial and industrial customers are subject to competition from other
suppliers of natural gas; however, NJNG continues to provide transportation
service to these customers. Based on its rate design, NJNG's profits would not
be negatively affected by a customer's decision to utilize a sales or a
transportation only service. At September 30, 1998 NJNG had 3,987 commercial and
industrial customers utilizing the transportation service.

  In January 1997, the BPU approved a Stipulation Agreement that provides
residential customers the option to choose their gas supplier. In April 1997,
the first 5,000 residential customers switched to a transportation service. In
September 1997, the BPU accelerated the schedule to allow an additional 25,000
residential customers to chose its supplier starting January 2, 1998. A
comprehensive agreement approved by the BPU in September 1998 provides all NJNG
customers the option to choose a natural gas supplier as early as January 1,
1999. On December 16, 1998 the BPU deferred the implementation of full customer
choice until the BPU has resolved certain policy issues related to a fully open
market. The BPU also allowed for the expansion of NJNG's residential supplier
choice pilot to accept an additional 10,000 customers. Based on its current and
projected level of transportation customers, the Company does not expect any
problems with its gas supply portfolio.

  See MD&A - NJNG Operations in the Company's 1998 Annual Report for a
discussion of NJNG's financial results.

NJR ENERGY HOLDINGS CORPORATION

  Energy Holdings includes the operations of Energy Services, Natural Energy and
NJR Energy.

  Natural Energy markets natural gas to retail customers. As of September 30,
1998, Natural Energy marketed natural gas to 7,502 retail customers. An
additional 8,600 residential customers have executed contracts and will begin
service in 1999. The increase is due to participation in residential pilot
programs. Energy Services provides fuel and capacity management services to
wholesale customers including GPU Service, Inc., an electric utility based in
Pennsylvania, Gas Energy, Inc. and Calpine Corporation, independent power
producers operating in New York. Energy Services also

                                       8
<PAGE>   11
purchases natural gas for Natural Energy and trades natural gas, under risk
management guidelines, primarily in Northeast markets.

  NJR Energy and its subsidiaries were involved in oil and natural gas
development, production, transportation, storage and other energy-related
ventures. In 1996, the Company exited the oil and natural gas production
business and sold the reserves and related assets of NJR Energy and NJNR.

  NJR Energy's continuing operations consist primarily of Pipelines' 2.8% equity
investment in the Iroquois Gas Transmission System, L.P., a 375-mile natural gas
pipeline from the Canadian border to Long Island.

  See MD&A - Energy Holdings in the Company's 1998 Annual Report for a
discussion of Energy Services, Natural Energy and NJR Energy's consolidated
financial results.

NJR DEVELOPMENT CORPORATION

  NJR Development consists solely of CR&R's operations.

  As of September 30, 1998, CR&R's completed space totaled 25,000 square feet in
two fully-occupied buildings. In fiscal 1998, CR&R sold a 280,000 square-foot
office building generating proceeds of $15.6 million and an after-tax gain of
$900,000.

  Consistent with the Company's previously disclosed strategy to realign its
asset base more closely with its core energy business, CR&R has sold a majority
of its real estate buildings over the past three years.

  In conjunction with one of the real estate sales, CR&R granted options to the
buyer to purchase approximately 165 of CR&R's remaining 183 acres of undeveloped
land. CR&R has retained limited rights to sell and develop the acreage that are
subject to the options.

  The Company used the sale proceeds from the abovementioned transactions to pay
down outstanding debt incurred to develop the real estate assets. The Company's
future earnings from operations will not be materially affected by these sales
based upon the historical earnings generated by the real estate subsidiary.

  See Item 2 - Properties - NJR Development Corporation for additional
information regarding CR&R's remaining real estate assets.

  See MD&A - NJR Development Operations in the Company's 1998 Annual Report for
a discussion of CR&R's financial results.


                                   ENVIRONMENT

  The Company and its subsidiaries are subject to legislation and regulation by
federal, state and local authorities with respect to environmental matters. The
Company believes that it is in substantial compliance with all applicable
environmental laws and regulations.

                                       9
<PAGE>   12
  CR&R is the owner of certain undeveloped acreage in the Monmouth Shores
Corporate Park (MSCP), located in Monmouth County, New Jersey. This acreage is
regulated by the provisions of the Freshwater Wetlands Protection Act (the Act),
which restricts building in areas defined as "freshwater wetlands" and their
transition areas.

  Based upon an environmental engineer's delineation of the wetland and
transition areas in accordance with the provisions of the Act, CR&R will file
for a Letter of Interpretation from the New Jersey Department of Environmental
Protection (NJDEP) as parcels of land are selected for development. Based upon
the environmental engineer's revised estimated developable yield for MSCP, the
Company does not believe that a reserve against this property was necessary as
of September 30, 1998.

  Although the Company cannot estimate with certainty future costs of
environmental compliance, which among other factors are subject to changes in
technology and governmental regulations, the Company does not presently
anticipate any additional significant future expenditures, other than the
activities described in Note 10 to the Consolidated Financial Statements -
Commitments and Contingent Liabilities in the Company's 1998 Annual Report, for
compliance with existing environmental laws and regulations which would have a
material effect upon the capital expenditures, earnings or competitive position
of the Company or its subsidiaries.

  See Item 3 - Legal Proceedings - a. Gas Remediation for additional information
regarding environmental activities.

                               EMPLOYEE RELATIONS

  The Company and its subsidiaries employed 791 and 824 employees at September
30, 1998 and 1997, respectively. NJNG had 466 and 495 union employees at
September 30, 1998 and 1997, respectively. In December 1997, NJNG reached
agreement with the union on a three-year collective bargaining agreement which
provides, among other things, for annual wage increases of 3.25%, 3% and 3%,
effective December 3, 1997 and December 8, 1998 and 1999, respectively.

ITEM 2. PROPERTIES

NJNG (All properties are in New Jersey)

  NJNG owns 11,170 miles of distribution main and services, 325 miles of
transmission main and approximately 385,400 meters. Mains are primarily located
under public roads. Where mains are located under private property, NJNG has
obtained easements from the owners of record.

  In addition to mains and services, NJNG owns and operates two LNG storage
plants located in Stafford Township, Ocean County, and Howell Township, Monmouth
County. The two LNG plants have an estimated maximum capacity of 19,200 and
150,000 Dths per day, respectively. These facilities are used for peaking supply
and emergencies.

  NJNG owns four service centers located in Rockaway Township, Morris County;
Atlantic Highlands and Wall Township, Monmouth County; and Lakewood, Ocean
County. These service centers house storerooms, garages, gas distribution and
appliance service operations and administrative offices. NJNG leases its

Asbury Park and Wall Township, Monmouth County and a service center in
Manahawkin, Ocean County. These customer service offices support customer
contact, marketing and other functions. NJNG also owns an equipment storage
facility in Long Branch, Monmouth County.

                                       12
<PAGE>   15
  Substantially all of NJNG's properties, not expressly excepted or duly
released, are subject to the lien of an Indenture of Mortgage and Deed of Trust
to Harris Trust and Savings Bank, Chicago, Illinois, dated April 1, 1952, as
amended by twenty-nine supplemental indentures (Indenture), as security for
NJNG's bonded debt, which totaled approximately $238 million at September 30,
1998. In addition, under the terms of its Indenture, NJNG could have issued
approximately $252 million of additional first mortgage bonds as of September
30, 1998. In January 1998, NJNG issued variable rate Series EE and Series FF
Bonds for $9.5 million and $15 million, respectively, due 2028 under its
Indenture. The proceeds were used to redeem the $9.5 million 7.05% Series T and
the $15 million 7.25% Series U Bonds on March 1, 1998. In April 1998, NJNG
entered into a loan agreement whereby the New Jersey Economic Development
Authority loaned NJNG the proceeds from its $18 million Natural Gas Facilities
Revenue Bonds, Series 1998C. Also in April 1998, NJNG drew down $2 million from
the construction fund and issued $2 million of its Series GG Bonds.

Energy Holdings

  Pipeline has a 2.8% equity interest in the Iroquois Gas Transmission System,
L.P. which owns and operates the Iroquois pipeline project, a 375-mile pipeline
located from the Canadian border in upstate New York to Long Island.

NJR Development Corporation  (All properties are in New Jersey)

  At September 30, 1998, CR&R owned 183 acres of undeveloped land and two
fully-occupied buildings. The buildings consisted of 25,000 square feet of
commercial office and mixed-use commercial/industrial space.

  See Item 1. Business - NJR Development  Corporation for a description of the

Report for a discussion of the Company's anticipated 1999 and 2000 capital
expenditures for each business segment.

ITEM 3. LEGAL PROCEEDINGS

a. Gas Remediation

  NJNG has identified eleven former manufactured gas plant (MGP) sites, dating
back to the late 1800's and early 1900's, which contain contaminated residues
from the former gas manufacturing operations. Ten of the eleven sites in
question were acquired by NJNG in 1952. All of the gas manufacturing operations
ceased at these sites at least by the mid-1950's and in some cases had been
discontinued many years earlier, and all of the old gas manufacturing facilities
were subsequently dismantled by NJNG or the former owner. NJNG is currently
involved in administrative proceedings with the NJDEP and local government
authorities with respect to the plant sites in question, and is participating in
various studies and investigations by outside consultants to determine the
nature and extent of any such contaminated residues and to develop appropriate
programs of remedial action, where warranted. Since October 1989, NJNG has
entered into Administrative Consent Orders or



                                       13
<PAGE>   16
Memoranda of Agreement with the NJDEP covering all eleven sites. These documents
establish the procedures to be followed by NJNG in developing a final remedial
clean-up plan for each site.

  Most of the cost of such studies and investigations is being shared under an
agreement with the former owner and operator of ten of the MGP sites. See Note
10 to the Consolidated Financial Statements - Commitments and Contingent
Liabilities in the Company's 1998 Annual Report for a discussion of the
regulatory treatment of gas remediation costs.

   In March 1995, NJNG filed a complaint in New Jersey Superior Court against
various insurance carriers for declaratory judgment and for damages arising from
such defendants' breach of their contractual obligations to defend and/or
indemnify NJNG against liability for claims and losses (including defense costs)
alleged against NJNG relating to environmental contamination at the former MGP
sites and other sites. NJNG is seeking (i) a declaration of the rights, duties
and liabilities of the parties under various primary and excess liability
insurance policies purchased from the defendants by NJNG from 1951 through 1985,
and (ii) compensatory and other damages, including costs and fees arising out of
defendants' obligations under such insurance policies. The complaint was amended
in July 1996 to name Kaiser-Nelson Steel & Salvage Company (Kaiser-Nelson) and
its successors as additional defendants. The Company is seeking (a) a
declaration of the rights, duties and liabilities of the parties under
agreements with respect to claims against the Company that allege property
damage caused by various substances used, handled or generated by NJNG or the
predecessor in title that were removed from several of the MGP sites by
Kaiser-Nelson, and (b) money damages or compensatory relief for the harm caused
by Kaiser-Nelson's aforementioned actions. Discovery is proceeding in this
matter. There can be no assurance as to the outcome of these proceedings.

b. South Brunswick Asphalt, L.P.

  NJNG has been named a defendant in a civil action commenced in New Jersey
Superior Court by South Brunswick Asphalt, L.P. (SBA) and its affiliated
companies seeking damages arising from alleged environmental contamination at
three sites owned or occupied by SBA and its affiliated companies. Specifically,
the suit charges that tar emulsion removed from 1979 through 1983 by an
affiliate of SBA (Seal Tite, Inc.) from NJNG's former gas manufacturing plant
sites has been alleged by the NJDEP to constitute a hazardous waste and that the
tar emulsion has contaminated the soil and ground water at the three sites in
question. In February 1991, the NJDEP issued letters classifying the tar
emulsion/sand and gravel mixture at each site as dry industrial waste, a
non-hazardous classification. In April 1996, in a meeting with all parties to
the litigation and the judge assigned to the case, the NJDEP confirmed the
non-hazardous classification, which will allow for conventional disposal. In May
1997, SBA submitted applications to NJDEP for permits to allow SBA to recycle
the tar emulsion/sand and gravel mixture at each site into asphalt, to be used
as a paving material. These applications are currently under review by NJDEP. In
July 1998, SBA filed an amended complaint adding NJDEP to the proceedings to
facilitate the resolution of the applications. The Company does not believe that
the ultimate resolution of these matters will have a material adverse effect on
its consolidated financial condition or results of operations.

c. BPU Inquiry

  On August 4, 1998, NJNG was informed by the BPU that the Audit Division staff
had concluded an informal review of certain gas purchases made by NJNG from 1989
to 1995, including purchases relating to the Freehold cogeneration project, and
was recommending that its conclusions be referred to the BPU's counsel for a
determination of whether any of the BPU's statutes or regulations may have


                                       14
<PAGE>   17
been violated. The Company has not been informed of the results of that
referral. The Company and NJNG are currently in discussions with senior staff of
the BPU concerning a possible resolution of the open audits and related BPU
docket items, including those related to the subject matter of the Audit
Division staff's informal review and the proper disposition of any proceeds NJNG
may receive from a settlement with the owners of the Freehold cogeneration
project. Although the Company cannot currently predict the outcome of such
discussions, management does not believe that a resolution of these matters as a
whole would have a material adverse effect on the Company's consolidated
financial condition or results of operations.

d. Various

  The Company is party to various other claims, legal actions and complaints
arising in the ordinary course of business. In management's opinion, the
ultimate disposition of these matters will not have a material adverse effect on
its financial condition or results of operations.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

  None

INFORMATION CONCERNING FORWARD LOOKING STATEMENTS

     Certain of the statements contained in this report (other than the
financial statements and other statements of historical fact), including,
without limitation, statements as to management expectations and belief
presented in Part I under the captions "New Jersey Natural Gas Company -
General; - Gas Supply; - Energy Deregulation Legislation; - Regulation and
Rates; - Competition," "Environment" and "Legal Proceedings", are
forward-looking statements. Forward-looking statements are made based upon
management's expectations and belief concerning future developments and their
potential effect upon the Company. There can be no assurance that future
developments will be in accordance with management's expectations or that the
effect of future developments on the Company will be those anticipated by
management.

   The Company wishes to caution readers that the assumptions which form the
basis for forward-looking statements with respect to or that may impact
financial results and capital requirements for fiscal 1999 and thereafter
include many factors that are beyond the Company's ability to control or
estimate precisely, such as estimates of future market conditions and the
behavior of other market participants. Among the factors that could cause actual
results to differ materially from estimates reflected in such forward-looking
statements are weather conditions, economic conditions, and demographic changes
in NJNG's service territory, fluctuations in energy commodity prices, conversion
activity and other marketing efforts, the conservation efforts of NJNG's
customers, the ability to extend certain fuel management contracts, the pace of
deregulation of retail gas markets, competition for the acquisition of gas, the
regulatory and pricing policies of federal and state regulatory agencies, the
availability of Canada's reserves for export to the United States and other
regulatory changes.

   While the Company periodically reassesses material trends and uncertainties
affecting the Company's results of operations and financial condition in
connection with its preparation of management's discussion and analysis of
results of operations and financial condition contained in its quarterly and
annual reports, the Company does not, by including this statement, assume any
obligation to review or revise any particular forward-looking statement
referenced herein in light of future events.

<PAGE>   13
                   Section 2.1. There shall be a twenty-ninth series of Bonds,
known as and entitled "First Mortgage Bonds, Adjustable Rate Series EE due 2028"
or "First Mortgage Bonds, Adjustable Rate Series EE" (herein and in the
Indenture referred to as the "2028 Series EE Bonds"), and the form thereof shall
contain suitable provisions with respect to the matters hereinafter in this
Section specified and shall in other respects be substantially as set forth in
the preambles to the Original Indenture.

         The aggregate principal amount of 2028 Series EE Bonds which may be
authenticated and delivered and outstanding under the Indenture is Nine Million
Five Hundred Forty-Five Thousand Dollars ($9,545,000).

         The 2028 Series EE Bonds shall be payable to the EDA Loan Trustee, and
shall be nontransferable except to a successor of the EDA Loan Trustee.

         The 2028 Series EE Bonds shall bear interest at the minimum rate per
annum necessary to yield interest in amounts sufficient, when taken together
with other amounts available therefor under the EDA Bond Indenture, to pay the
interest from time to time payable on the 1998A EDA Bonds, computed on the same
basis as the 1998A EDA Bonds (interest on overdue principal and premium, if any,
and, to the extent legally enforceable, interest, being at the rate of six
percent (6%) per annum), but in no event shall the interest rate on the 2028
Series EE Bonds exceed ten percent (10%) per annum; and the 2028 Series EE Bonds
shall mature on January 1, 2028, subject to prior redemption as described
herein. The amount of "annual interest charges" on the 2028 Series EE Bonds,
within the meaning of any provision of the Indenture requiring a determination
of said amount as a condition to the issuance of any Bonds thereunder
(including, without limitation, the 2028 Series EE Bonds), shall mean the amount
calculated by applying to the 2028 Series EE Bonds the interest rate of ten
percent (10%) per annum; provided, however, that if the rate of interest on the
1998A EDA Bonds shall have become fixed and determined at a per annum rate lower
than ten percent (10%) for a period not less than the remaining maturity of said
1998A EDA Bonds (whether said 1998A EDA Bonds shall mature at their stated
maturity, by earlier redemption or otherwise), then said lower rate shall be
used to determine the amount of the "annual interest charges" on the 2028 Series
EE Bonds.

         The 2028 Series EE Bonds shall be in the form of registered Bonds
without coupons of denominations of Five Thousand Dollars ($5,000) and any
integral multiple thereof which may be authorized by the Company, the issue of a
registered Bond without coupons in any such denomination to be conclusive
evidence of such authorization. The 2028 Series EE Bonds shall be dated as
provided in Section 2.05 of the Indenture. All 2028 Series EE Bonds shall bear
interest from their respective dates, such interest to be payable, upon the
terms of and otherwise in accordance with the 2028 Series EE Bonds, on the first
business day preceding each date on which interest shall from time to time be
payable on the 1998A EDA Bonds; provided, that the obligation of the Company to
make payments with respect to the principal of, premium, if any, and interest on
the 2028 Series EE Bonds shall be fully or partially, as the case may be,
satisfied and discharged to the extent that at

                                      -12-
<PAGE>   14
the time any such payment shall be due, the then due principal of, premium, if
any, and interest on any of the 1998A EDA Bonds shall have been fully or
partially paid from payments made by the Company under the Loan Agreement or
from other moneys expressly available therefor in the principal and interest
account for the 1998A EDA Bonds under the EDA Bond Indenture or, as far as
principal is concerned, reduced by the principal amount of any of the 1998A EDA
Bonds deemed paid pursuant to Article X of the EDA Bond Indenture. The principal
of and the premium, if any, and interest on the 2028 Series EE Bonds shall be
payable at the principal office of the Trustee, in the City of Chicago,
Illinois, or, at the option of the Company, at the "Principal Office" (as that
term is defined in the EDA Bond Indenture) of the EDA Loan Trustee, in any coin
or currency of the United States of America which at the time of payment shall
be legal tender for the payment of public and private debts.

         Notwithstanding any other provision of the Indenture or of the 2028
Series EE Bonds, payments of the principal of and the premium, if any, and
interest on any 2028 Series EE Bond may be made directly to the registered
holder thereof without presentation or surrender thereof or the making of any
notation thereon if there shall be filed with the Trustee a Certificate of the
Company to the effect that such registered holder (or the person for whom such
registered holder is a nominee) and the Company have entered into a written
agreement that payment shall be so made; provided, however, that before such
registered holder transfers or otherwise disposes of any 2028 Series EE Bond,
such registered holder will, at its election, either endorse thereon (or on a
paper annexed thereto) the principal amount thereof redeemed and the last date
to which interest has been paid thereon or make such Bond available to the
Company at the principal office of the Trustee for the purpose of making such
endorsement thereon. The 2028 Series EE Bonds shall be subject to redemption at
the option of the Company or otherwise, in the manner provided in the applicable
provisions of Article Ten of the Indenture, as amended by Article IV of this
Supplemental Indenture.

         The 2028 Series EE Bonds shall be excluded from the benefits of, and
shall not be subject to redemption through the operation of, a Mandatory Sinking
Fund pursuant to Section 11.02 of the Indenture and shall also be excluded from
the benefits of the covenants of Section 9.08 and Section 11.01 of the
Indenture.

         Notwithstanding the provisions of Section 10.04 or any other provision
of the Indenture, the selection of 2028 Series EE Bonds to be redeemed shall, in
case fewer than all of the outstanding 2028 Series EE Bonds are to be redeemed,
be made by the Trustee pro rata (to the nearest multiple of Five Thousand
Dollars ($5,000)) among the registered holders of the 2028 Series EE Bonds in
proportion, as nearly as practicable, to the respective unpaid principal amounts
of 2028 Series EE Bonds registered in the names of such holders, with
adjustments, to the extent practicable, to compensate for any prior redemption
not made exactly in such proportion (or otherwise as may be specified by a
written order signed by the registered holders of all outstanding 2028 Series EE
Bonds).

                                      -13-
<PAGE>   15
         The definitive 2028 Series EE Bonds may be issued in the form of
engraved Bonds or Bonds printed or lithographed on steel engraved borders or
Bonds in typed form on normal bond paper. Subject to the foregoing provisions of
this Section and the provisions of Section 2.11 of the Indenture, all definitive
2028 Series EE Bonds shall be fully exchangeable for other Bonds of the same
series, of like aggregate principal amounts, and, upon surrender to the Trustee
at its principal office, shall be exchangeable for other Bonds of the same
series of a different authorized denomination or denominations, as requested by
the holder surrendering the same. The Company will execute, and the Trustee
shall authenticate and deliver, registered Bonds without coupons, whenever the
same shall be required for any such exchange.

                   Section 2.2. 2028 Series EE Bonds in the aggregate principal
amount of Nine Million Five Hundred Forty-Five Thousand Dollars ($9,545,000) may
forthwith upon the execution and delivery of this Supplemental Indenture, or
from time to time thereafter, be executed by the Company and delivered to the
Trustee, and shall thereupon be authenticated and delivered by the Trustee upon
compliance by the Company with the provisions of Articles Four, Five or Six of
the Indenture, without awaiting the filing or recording of this Supplemental
Indenture. No additional 2028 Series EE Bonds shall be issued under Article
Four, Five or Six without the consent in writing of the holders of all the
outstanding 2028 Series EE Bonds.

                                  ARTICLE III.

                              2028 SERIES FF BONDS

                  Section 3.1. There shall be a thirtieth series of Bonds, known
as and entitled "First Mortgage Bonds, Adjustable Rate Series FF due 2028" or
"First Mortgage Bonds, Adjustable Rate Series FF" (herein and in the Indenture
referred to as the "2028 Series FF Bonds"), and the form thereof shall contain
suitable provisions with respect to the matters hereinafter in this Section
specified and shall in other respects be substantially as set forth in the
preambles to the Original Indenture.

         The aggregate principal amount of 2028 Series FF Bonds which may be
authenticated and delivered and outstanding under the Indenture is Fifteen
Million Dollars ($15,000,000).

         The 2028 Series FF Bonds shall be payable to the EDA Loan Trustee, and
shall be nontransferable except to a successor of the EDA Loan Trustee.

         The 2028 Series FF Bonds shall bear interest at the minimum rate per
annum necessary to yield interest in amounts sufficient, when taken together
with other amounts available therefor under the EDA Bond Indenture, to pay the
interest from time to time payable on the 1998B EDA Bonds, computed on the same
basis as the 1998B EDA Bonds (interest on overdue principal and premium, if any,
and, to the extent legally enforceable, interest, being at the rate of six
percent (6%) per annum), but in

                                      -14-
<PAGE>   16
no event shall the interest rate on the 2028 Series FF Bonds exceed ten percent
(10%) per annum; and the 2028 Series FF Bonds shall mature on January 1, 2028,
subject to prior redemption as described herein. The amount of "annual interest
charges" on the 2028 Series FF Bonds, within the meaning of any provision of the
Indenture requiring a determination of said amount as a condition to the
issuance of any Bonds thereunder (including, without limitation, the 2028 Series
FF Bonds), shall mean the amount calculated by applying to the 2028 Series FF
Bonds the interest rate of ten percent (10%) per annum; provided, however, that
if the rate of interest on the 1998B EDA Bonds shall have become fixed and
determined at a per annum rate lower than ten percent (10%) for a period not
less than the remaining maturity of said 1998B EDA Bonds (whether said 1998B EDA
Bonds shall mature at their stated maturity, by earlier redemption or
otherwise), then said lower rate shall be used to determine the amount of the
"annual interest charges" on the 2028 Series FF Bonds.

         The 2028 Series FF Bonds shall be in the form of registered Bonds
without coupons of denominations of Five Thousand Dollars ($5,000) and any
integral multiple thereof which may be authorized by the Company, the issue of a
registered Bond without coupons in any such denomination to be conclusive
evidence of such authorization. The 2028 Series FF Bonds shall be dated as
provided in Section 2.05 of the Indenture. All 2028 Series FF Bonds shall bear
interest from their respective dates, such interest to be payable, upon the
terms of and otherwise in accordance with the 2028 Series FF Bonds, on the first
business day preceding each date on which interest shall from time to time be
payable on the 1998B EDA Bonds; provided, that the obligation of the Company to
make payments with respect to the principal of, premium, if any, and interest on
the 2028 Series FF Bonds shall be fully or partially, as the case may be,
satisfied and discharged to the extent that at the time any such payment shall
be due, the then due principal of, premium, if any, and interest on any of the
1998B EDA Bonds shall have been fully or partially paid from payments made by
the Company under the Loan Agreement or from other moneys expressly available
therefor in the principal and interest account for the 1998B EDA Bonds under the
EDA Bond Indenture or, as far as principal is concerned, reduced by the
principal amount of any of the 1998B EDA Bonds deemed paid pursuant to Article X
of the EDA Bond Indenture. The principal of and the premium, if any, and
interest on the 2028 Series FF Bonds shall be payable at the principal office of
the Trustee, in the City of Chicago, Illinois, or, at the option of the Company,
at the "Principal Office" (as that term is defined in the EDA Bond Indenture) of
the EDA Loan Trustee, in any coin or currency of the United States of America
which at the time of payment shall be legal tender for the payment of public and
private debts.

         Notwithstanding any other provision of the Indenture or of the 2028
Series FF Bonds, payments of the principal of and the premium, if any, and
interest on any 2028 Series FF Bond may be made directly to the registered
holder thereof without presentation or surrender thereof or the making of any
notation thereon if there shall be filed with the Trustee a Certificate of the

registered holder is a nominee) and the Company have entered 

                                      -15-

into a written agreement that payment shall be so made; provided, however, that
before such registered holder transfers or otherwise disposes of any 2028 Series
FF Bond, such registered holder will, at its election, either endorse thereon
(or on a paper annexed thereto) the principal amount thereof redeemed and the
last date to which interest has been paid thereon or make such Bond available to
the Company at the principal office of the Trustee for the purpose of making
such endorsement thereon.

         The 2028 Series FF Bonds shall be subject to redemption at the option
of the Company or otherwise, in the manner provided in the applicable provisions
of Article Ten of the Indenture, as amended by Article V of this Supplemental
Indenture.

         The 2028 Series FF Bonds shall be excluded from the benefits of, and
shall not be subject to redemption through the operation of, a Mandatory Sinking
Fund pursuant to Section 11.02 of the Indenture and shall also be excluded from
the benefits of the covenants of Section 9.08 and Section 11.01 of the
Indenture.

         Notwithstanding the provisions of Section 10.04 or any other provision
of the Indenture, the selection of 2028 Series FF Bonds to be redeemed shall, in
case fewer than all of the outstanding 2028 Series FF Bonds are to be redeemed,

           Section 1.1. The Original Indenture, as heretofore amended, be and it
hereby is further amended in the following respects, the section numbers
specified below being the sections of the Indenture in which such amendments
occur:

          Section l.01.   The following definition be and it hereby is added

      "'TWENTY-NINTH SUPPLEMENTAL INDENTURE' shall mean the Supplemental

          Section 1.01.   The following definition be and it hereby is added

      "'2033 SERIES GG BOND' shall mean one of the First Mortgage Bonds,
      Adjustable Rate Series GG due 2033, issued hereunder."

            Section 2.11. The following be and it hereby is added at the end of

      registration of transfer thereof."

          Section 8.08. The period at the end of the first paragraph of Section

      specified in Section 10.74 and Section 10.77."

                                   ARTICLE II.

                              2033 SERIES GG BONDS

           Section 2.1. There shall be a thirty-first series of Bonds, known as
and entitled "First Mortgage Bonds, Adjustable Rate Series GG due 2033"


                                      -11-
<PAGE>   13
or "First Mortgage Bonds, Adjustable Rate Series GG" (herein and in the
Indenture referred to as the "2033 Series GG Bonds"), and the form thereof shall
contain suitable provisions with respect to the matters hereinafter in this
Section specified and shall in other respects be substantially as set forth in
the preambles to the Original Indenture.

      The aggregate principal amount of 2033 Series GG Bonds which may be
authenticated and delivered and outstanding under the Indenture is Eighteen
Million Dollars ($18,000,000).

      The 2033 Series GG Bonds shall be payable to the EDA Loan Trustee, and
shall be nontransferable except to a successor of the EDA Loan Trustee.

      The 2033 Series GG Bonds shall bear interest at the minimum rate per annum
necessary to yield interest in amounts sufficient, when taken together with
other amounts available therefor under the EDA Bond Indenture, to pay the
interest from time to time payable on the 1998C EDA Bonds, computed on the same
basis as the 1998C EDA Bonds (interest on overdue principal and premium, if any,
and, to the extent legally enforceable, interest, being at the rate of six
percent (6%) per annum), but in no event shall the interest rate on the 2033
Series GG Bonds exceed ten percent (10%) per annum; and the 2033 Series GG Bonds
shall mature on April 1, 2033, subject to prior redemption as described herein.
The amount of "annual interest charges" on the 2033 Series GG Bonds, within the
meaning of any provision of the Indenture requiring a determination of said
amount as a condition to the issuance of any Bonds thereunder (including,
without limitation, the 2033 Series GG Bonds), shall mean the amount calculated
by applying to the 2033 Series GG Bonds the interest rate of ten percent (10%)
per annum; provided, however, that if the rate of interest on the 1998C EDA
Bonds shall have become fixed and determined at a per annum rate lower than ten
percent (10%) for a period not less than the remaining maturity of said 1998C
EDA Bonds (whether said 1998C EDA Bonds shall mature at their stated maturity,
by earlier redemption or otherwise), then said lower rate shall be used to
determine the amount of the "annual interest charges" on the 2033 Series GG
Bonds.

      The 2033 Series GG Bonds shall be in the form of registered Bonds without
coupons of denominations of Five Thousand Dollars ($5,000) and any integral
multiple thereof which may be authorized by the Company, the issue of a
registered Bond without coupons in any such denomination to be conclusive
evidence of such authorization. The 2033 Series GG Bonds shall be dated as
provided in Section 2.05 of the Indenture. All 2033 Series GG Bonds shall bear
interest from their respective dates, such interest to be payable, upon the
terms of and otherwise in accordance with the 2033 Series GG Bonds, on the first
business day preceding each date on which interest shall from time to time be
payable on the 1998C EDA Bonds; provided, that the obligation of the Company to
make payments with respect to the principal of, premium, if any, and interest on
the 2033 Series GG Bonds shall be fully or partially, as the case may be,
satisfied and discharged to the extent that at the time any such payment shall
be due, the


                                      -12-
<PAGE>   14
then due principal of, premium, if any, and interest on any of the 1998C EDA
Bonds shall have been fully or partially paid from payments made by the Company
under the Loan Agreement or from other moneys expressly available therefor in
the principal and interest account for the 1998C EDA Bonds under the EDA Bond
Indenture or, as far as principal is concerned, reduced by the principal amount
of any of the 1998C EDA Bonds deemed paid pursuant to Article X of the EDA Bond
Indenture. The principal of and the premium, if any, and interest on the 2033
Series GG Bonds shall be payable at the principal office of the Trustee, in the
City of Chicago, Illinois, or, at the option of the Company, at the "Principal
Office" (as that term is defined in the EDA Bond Indenture) of the EDA Loan
Trustee, in any coin or currency of the United States of America which at the
time of payment shall be legal tender for the payment of public and private
debts.

      Notwithstanding any other provision of the Indenture or of the 2033 Series
GG Bonds, payments of the principal of and the premium, if any, and interest on
any 2033 Series GG Bond may be made directly to the registered holder thereof
without presentation or surrender thereof or the making of any notation thereon
if there shall be filed with the Trustee a Certificate of the Company to the
effect that such registered holder (or the person for whom such registered
holder is a nominee) and the Company have entered into a written agreement that
payment shall be so made; provided, however, that before such registered holder
transfers or otherwise disposes of any 2033 Series GG Bond, such registered
holder will, at its election, either endorse thereon (or on a paper annexed
thereto) the principal amount thereof redeemed and the last date to which
interest has been paid thereon or make such Bond available to the Company at the
principal office of the Trustee for the purpose of making such endorsement
thereon.

      The 2033 Series GG Bonds shall be subject to redemption at the option of
the Company or otherwise, in the manner provided in the applicable provisions of
Article Ten of the Indenture, as amended by Article IV of this Supplemental
Indenture.

      The 2033 Series GG Bonds shall be excluded from the benefits of, and shall
not be subject to redemption through the operation of, a Mandatory Sinking Fund
pursuant to Section 11.02 of the Indenture and shall also be excluded from the
benefits of the covenants of Section 9.08 and Section 11.01 of the Indenture.

      Notwithstanding the provisions of Section 10.04 or any other provision of
the Indenture, the selection of 2033 Series GG Bonds to be redeemed shall, in
case fewer than all of the outstanding 2033 Series GG Bonds are to be redeemed,
be made by the Trustee pro rata (to the nearest multiple of Five Thousand
Dollars ($5,000)) among the registered holders of the 2033 Series GG Bonds in
proportion, as nearly as practicable, to the respective unpaid principal amounts
of 2033 Series GG Bonds registered in the names of such holders, with
adjustments, to the extent practicable, to compensate for any prior redemption
not made exactly in such proportion (or otherwise as may be specified by a
written order signed by the registered holders of all outstanding 2033 Series GG
Bonds).


                                      -13-
<PAGE>   15
      The definitive 2033 Series GG Bonds may be issued in the form of engraved
Bonds or Bonds printed or lithographed on steel engraved borders or Bonds in
typed form on normal bond paper. Subject to the foregoing provisions of this
Section and the provisions of Section 2.11 of the Indenture, all definitive 2033
Series GG Bonds shall be fully exchangeable for other Bonds of the same series,
of like aggregate principal amounts, and, upon surrender to the Trustee at its
principal office, shall be exchangeable for other Bonds of the same series of a
different authorized denomination or denominations, as requested by the holder
surrendering the same. The Company will execute, and the Trustee shall
authenticate and deliver, registered Bonds without coupons, whenever the same
shall be required for any such exchange.

           Section 2.2. 2033 Series GG Bonds in the aggregate principal amount
of Eighteen Million Dollars ($18,000,000) may forthwith upon the execution and
delivery of this Supplemental Indenture, or from time to time thereafter, be
executed by the Company and delivered to the Trustee, and shall thereupon be
authenticated and delivered by the Trustee upon compliance by the Company with
the provisions of Articles Four, Five or Six of the Indenture, without awaiting
the filing or recording of this Supplemental Indenture. No additional 2033
Series GG Bonds shall be issued under Article Four, Five or Six without the
consent in writing of the holders of all the outstanding 2033 Series GG Bonds.

                                 ARTICLE III

                    REDEMPTION OF THE 2033 SERIES GG BONDS

           Section 3.1. The following Section 10.77 and Section 10.78 be and
they hereby are added to Article Ten of the Indenture:

        "Section 10.77. The 2033 Series GG Bonds shall be subject to mandatory
redemption as follows: payments of principal of and premium on the 2033 Series
GG Bonds shall be made to the EDA Loan Trustee to redeem 2033 Series GG Bonds in
such amounts as shall be necessary, in accordance with the provisions of the
Loan Agreement, to provide funds under the Loan Agreement to (a) make, when due,
payment at maturity (including, without limitation, maturity upon acceleration
of the 1998C EDA Bonds) and (b) make, when due, any prepayment required by the
Loan Agreement in connection with any mandatory or optional redemption of 1998C
EDA Bonds; provided, however, that the obligation of the Company to make any
redemption payments under this Section shall be fully or partially, as the case
may be, satisfied and discharged to the extent that at any time such payment
shall be due, the then due payment at maturity or redemption payment on any of
the 1998C EDA Bonds shall have been fully or partially made from payments made
by the Company under the Loan Agreement or from other moneys expressly available
therefor in a redemption account or subaccount for the 1998C EDA Bonds under the
EDA Bond Indenture or, as far as principal is concerned, reduced by the
principal amount of any 1998C EDA Bonds deemed paid pursuant to Article X of the
EDA Bond Indenture. Terms used and not defined in this


                                     -14-

Supplemental Indenture dated as of April 1, 1998."

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND
RESULTS OF OPERATIONS                           New Jersey Resources Corporation




RESULTS OF OPERATIONS

CONSOLIDATED

Net income increased 5% to $41.8 million in 1998, compared with $39.9 million in
1997 and $37.1 million in 1996. The increase each year was primarily
attributable to continued profitable customer growth in New Jersey Natural Gas
Company (NJNG), the principal subsidiary of New Jersey Resources
Corporation (the Company).

Basic earnings per share increased 6% to $2.35 in 1998, compared with $2.22 in
1997 and $2.06 in 1996. Diluted earnings per share were $2.33, $2.21 and $2.05
in 1998, 1997 and 1996, respectively.

Dividends declared per share increased 2.5% to $1.64 in 1998, compared with
$1.60 in 1997 and $1.55 in 1996.


NJNG OPERATIONS

NJNG is a natural gas distribution company that provides regulated energy and
appliance services to more than 385,000 residential and commercial customers in
central and northern New Jersey, and participates in the off-system sales and
capacity release markets.

NJNG's financial results are summarized as follows:

</TABLE>

GROSS MARGIN

Effective January 1, 1998, gross margin is defined as gas revenues less gas
costs, sales tax and a transitional energy facilities assessment (TEFA). Gross
margin provides a more meaningful basis for evaluating utility operations, since
gas costs, sales tax and TEFA are passed through to customers and, therefore,
have no effect on earnings. Gas costs are charged to operating expenses on the
basis of therm sales at the rates included in NJNG's tariff. The Levelized Gas
Adjustment (LGA) clause allows NJNG to recover gas costs that exceed the level
reflected in its base rates. Sales tax is calculated at 6% of revenue and
excludes sales to other utilities, off-system sales and federal accounts. TEFA
is calculated on a per therm basis and excludes sales to other utilities and
off-system sales. Prior to January 1, 1998, gross margin was defined as gas
revenues less gas costs and gross receipts and franchise taxes (GRFT), which
were replaced by the sales tax, state income tax and TEFA.

State income taxes are included in operating expenses. The revised tax structure
will allow NJNG to be more competitive with other energy providers, and has not
adversely impacted NJNG's net income. (See Note 1: Summary of Significant
Accounting Policies).

The comparison of gross margin between periods will be impacted by the state tax
change described above.

RESIDENTIAL AND COMMERCIAL

Residential and commercial (i.e., firm) gross margin is subject to a
Weather-Normalization Clause (WNC), which provides for a revenue adjustment if
the weather varies by more than one-half of 1% from normal, or 20-year average,
weather. The WNC does not fully protect NJNG from factors such as unusually warm
weather and declines in customer usage patterns, which were set at the
conclusion of NJNG's last base rate case in January 1994. The accumulated
adjustment from one heating season (i.e., October-May) is billed or credited to
customers in subsequent periods. This mechanism reduces the variability of both
customer bills and NJNG's earnings due to weather fluctuations.

NJNG added 11,819 and 11,708 new customers, and converted the heating systems of
another 865 and 1,048 existing customers in 1998 and 1997, respectively. The
growth in 1998 represents an annual increase of approximately 1.9 Billion cubic
feet (Bcf), or 4.5%, in sales to firm customers.

Gross margin from sales to firm customers increased $1.5 million, or 1%, in
1998, and $4.2 million, or 3%, in 1997 due to customer growth, the impact of the
WNC and state tax law changes.

Sales to firm customers were 42.6 Bcf in 1998, compared with 45.7 Bcf in 1997
and 50.4 Bcf in 1996. The decreases in sales were due to 9% and 15% warmer
weather and the impact of customers switching to firm transportation service,
which more than offset customer growth in 1998 and 1997, respectively.

The weather in 1998 was 11% warmer than normal, which, in accordance with the
WNC, resulted in $12.2 million of gross margin being accrued for future recovery
from customers. In 1997, warmer-than-normal weather resulted in $3.3 million of
gross margin being accrued and recovered from customers in 1998. In 1996,
colder-than-normal weather resulted in $11.9 million of gross margin being
deferred and credited to customers in 1997.

In both 1999 and 2000, NJNG's goal is to add 11,800 to 12,000 new customers, and
convert an additional 950 existing customers each year to natural gas heat.
Achieving these goals would represent a customer growth rate of more than 3% and
result in a sales increase of approximately 1.9 Bcf per year, assuming normal
weather and average use, and increase gross margin under present rates by
approximately $5.5 million per year.

These growth goals are based upon management's review of county and municipal
planning board activity, builder surveys and studies of population growth rates
in NJNG's service territory. However, future sales will be affected by the
weather, economic conditions in NJNG's service territory, conversion activity,
the impact of changing from a regulated to a competitive environment, and other
marketing efforts, as has been the case in prior years.

A comprehensive agreement approved by the New Jersey Board of Public Utilities
(BPU) in September 1998 provides all NJNG customers the option to choose a
natural gas supplier as early as January 1, 1999, which makes NJNG the first New
Jersey energy supplier to make such an offer. In addition, the BPU approved the
extension of existing margin-sharing programs as well as a new incentive
program (see "Off-System and Capacity Release" below). As part of the agreement,
the BPU also set forth a recovery schedule designed to collect $34.9 million of
deferred gas costs over three years.

NJNG's goal is to continue to grow without increasing its base rates in order to
remain competitive as the utility industry transitions to a more market-based
environment.

FIRM TRANSPORTATION

Gross margin from firm transportation customers increased 25% to $18.3 million
in 1998 as more customers chose this service. NJNG transported 6.6 Bcf for its
firm customers in 1998, compared with 5.5 Bcf in 1997 and 4.5 Bcf in 1996.

At September 30, 1998 and 1997, NJNG provided firm transportation service to
16,495 and 7,647 customers, respectively. Transportation customers are expected
to grow as customers select other suppliers. An additional 5,500 customers have
executed contracts and will begin transportation service in 1999.

NJNG's total gross margin is not negatively impacted by customers who utilize
its firm transportation service and purchase their gas from another supplier, as
NJNG's tariffs are designed such that no profit is earned on the commodity
portion of sales to firm customers, and all customers who do purchase gas from
another supplier continue to utilize NJNG for transportation.

OFF-SYSTEM AND CAPACITY RELEASE

In order to reduce the overall cost of its gas supply commitments, NJNG has
entered into contracts to sell gas to customers outside its franchise territory
when the gas is not needed for system requirements. These sales enable NJNG to
spread its fixed demand costs, which are charged by pipelines to access their
supplies year round, over a larger and more diverse customer base. NJNG also
participates in the capacity release market on the interstate pipeline network
when the capacity is not needed for its own system requirements. Through
September 30, 1998, NJNG retained 20% of the gross margin from these sales, with
the balance credited to firm sales customers through the LGA clause. Effective
October 1, 1998 through December 31, 2001, NJNG will retain 15% of the gross
margin from these sales.

Also effective October 1, 1998, is a new incentive mechanism designed to reduce
the fixed cost of NJNG's gas supply portfolio. Any savings achieved through the
permanent reduction or replacement of capacity or other services will be shared
between customers and shareowners. Under this program, NJNG retains 40% of the
savings for the first 12 months following any transaction and retains 15% for
the remaining period through December 31, 2001, with the balances credited to
firm sales customers through the LGA clause.

NJNG's off-system sales totaled 62.2 Bcf and generated $2.6 million of gross
margin in 1998, compared with 44.7 Bcf and $3 million of gross margin in 1997
and 23.8 Bcf and $1.6 million of gross margin in 1996. The gross margin
generated by the capacity release program was $2.3 million in 1998, compared
with $2.4 million in 1997 and $3 million in 1996. The margin decreases in both
programs in 1998 were due primarily to warmer weather, which increased the
availability of supply and capacity and resulted in lower margins per therm.

INTERRUPTIBLE 

NJNG serves 49 customers through interruptible sales and/or transportation
tariffs. Sales made under the interruptible sales tariff are priced on
market-sensitive oil and gas parity rates. Although therms sold and transported
to interruptible customers represented 6% of total throughput in 1998 and 7% in
1997, they accounted for less than 1% of the total gross margin in each year due
to the margin-sharing formulas that govern these sales. Under these formulas,
NJNG retains 10% of the gross margin from interruptible sales and 5% of the
gross margin from transportation sales, with the balance credited to firm sales
customers through the LGA clause. Interruptible sales were 2 Bcf in 1998,
compared with 1.5 Bcf in 1997 and 1.4 Bcf in 1996. In addition, NJNG transported
8.6 Bcf, 8.2 Bcf and 8.4 Bcf in 1998, 1997 and 1996, respectively, for its
interruptible customers.

APPLIANCE SERVICE REVENUES

Revenues from appliance service contracts and service calls increased 10% in
1998 due to the addition of 9,400 service contracts. Revenues increased 40% in
1997 due to an overall 30% increase in rates charged for such services effective
April 1996. Costs related to this service work are primarily included
in operation and maintenance expenses.

OPERATING INCOME BEFORE FEDERAL INCOME TAXES 

Operating income before federal income taxes decreased 1% in 1998 and increased
6% in 1997. The 1998 results were adversely affected by reduced sales because of
warmer winter weather and a higher level of depreciation expense on utility
plant, which includes the capitalized costs of a new customer information and
billing system (CIS) placed in service in 1997, which were partially offset by
customer growth and increased appliance service revenues and lower operation and
maintenance expenses. Operation and maintenance expenses declined by 1% due to
lower fringe benefit costs and other cost control efforts. The 1997 increase was
primarily due to higher gross margin and appliance service revenues, which more
than offset higher operating expenses.



                                                                              25

NET INCOME

Net income increased 4% to $39.1 million in 1998 and 5% to $37.5 million in
1997. The 1998 increase was due to lower interest expense and lower federal
income taxes, which more than offset lower operating income before taxes. The
1997 increase was the result of increased operating income, which more than
offset higher interest costs and income taxes.

ENERGY HOLDINGS OPERATIONS

NJR Energy Holdings Corporation's (Energy Holdings) consolidated financial
results, which include NJR Energy Services Company (Energy Services), and New
Jersey Natural Energy Company (Natural Energy), the Company's unregulated fuel
and capacity management and marketing subsidiaries, and the continuing
operations of NJR Energy Corporation (NJR Energy), which includes an equity
investment in the Iroquois Gas Transmission System, L.P. (Iroquois), are

</TABLE>

Energy Holdings' energy deliveries and gas under management increased to 82.9
Bcf in 1998, compared with 67.3 Bcf in 1997 and 28.7 Bcf in 1996. Retail sales
were 6.7 Bcf in 1998, compared with 9.1 Bcf in 1997 and 8.9 Bcf in 1996. Natural
Energy had 7,502 and 6,949 retail customers at September 30, 1998 and 1997,
respectively. An additional 8,600 customers have executed contracts and will
begin service in 1999. The increase is due to participation in residential pilot
programs.

The decline in Energy Holdings' gross margin, operating income and net income in
1998 was primarily due to the impact of warmer weather, changes in state tax
laws and increased competition. Operating income before federal income taxes and
net income decreased in 1997, primarily due to lower retail marketing results,
which more than offset increased wholesale marketing results.

NJR Energy's results include interest expense related to debt remaining after
the discontinuance of the oil and natural gas production business in 1994. The
Company plans to further reduce such debt from cash flow generated by its equity
investment in Iroquois.

Future results are subject to Energy Holdings' ability to grow its retail
customer base with more marketing services, expand its fuel management
agreements and increase its wholesale marketing activity.

NJR DEVELOPMENT OPERATIONS

NJR Development Corporation's financial results, which consist solely of
Commercial Realty & Resources Corp.'s (CR&R) operations, are summarized as
follows:

                                            ------------------------------------
</TABLE>

In 1998, CR&R sold a 280,000 square-foot office building for $15.6 million.
Included in Other income, net is an after-tax gain of $900,000 related to this
transaction. 

In 1996, CR&R entered into a sale-leaseback transaction, which generated a
pre-tax gain of $17.8 million, which is included in Deferred revenue and is
being amortized to Other income, net over 25 years in accordance with generally
accepted accounting principles. The primary tenant of the facility, NJNG, is
leasing the building under a long-term master lease agreement and continues to
occupy a majority of the space in the building.

The net loss in 1997 was due primarily to interest expense related to debt
remaining after the sale of certain real estate assets in 1996.

THE YEAR 2000 ISSUE

The Company's overall goal is to be Year 2000 ready. "Year 2000 ready" means
that critical systems, devices, applications or business relationships have been
evaluated and are expected to be suitable for continued use into and beyond the
Year 2000, or contingency plans are in place. 

The Company began addressing the Year 2000 issue in 1994 by assessing its
enterprise computer systems, such as general ledger, payroll, inventory control,
accounts receivable and CIS. The majority of these systems have been replaced
and have been running the Company's day-to-day computing environment since 1995.
The vendor of the software systems notified the Company that the new CIS,
installed in August 1997, is Year 2000 compliant and the balance of the systems
will be compliant with a scheduled system upgrade that will take place the first
half of 1999.

In 1997, a Year 2000 Project was established to provide leadership and direction
to the Year 2000 efforts throughout the Company and its subsidiaries. The
project scope was also expanded to include "embedded" systems (such as chart
recorders, data loggers and calibration equipment), end-user computing hardware
and software, plant and corporate facilities, gas control hardware and software,
meter reading equipment and remittance processing equipment, and business
relationships with key suppliers and customers. Additionally, the Year 2000
Project includes intelligent devices used in field operations.

                                                New Jersey Resources Corporation



The Company is using a multi-step approach in conducting its Year 2000 Project.
These steps are: inventory, assessment, remediation, testing, and contingency
planning. The first step, an inventory of all systems and devices with potential
Year 2000 problems, was completed in May 1998. The next step, also completed in
May 1998, was to conduct an initial assessment of the inventory to determine the
state of its Year 2000 readiness. As part of the assessment phase, remediation
strategies are being identified and remediation cost estimates are being
developed. The Company will utilize both internal and external resources to
remediate and test for Year 2000 readiness. The testing and contingency phases
are scheduled to end in August 1999. The Company has initiated formal
communications with the suppliers with which it has active contracts to
determine the extent to which the Company is vulnerable to those third parties'
failure to remediate their own Year 2000 issues. Key vendors have been mailed
surveys regarding their Year 2000 compliance, however not all responses have
been received. The Company will continue to pursue its key vendors to obtain
their Year 2000 readiness.

COSTS

The capitalized costs through September 30, 1998 of updating its enterprise
computer systems, including the CIS described above, was $18 million. The
Company expects to incur $6.4 million in 1999 for projects which will also
address Year 2000 readiness, of which $6.1 million is for new software and
hardware which the Company expects to capitalize. The costs of the projects and
the date on which the Company plans to complete the Year 2000 modifications are
based on management's best estimates, which were derived utilizing numerous
assumptions of future events including the continued availability of certain
resources, third parties' Year 2000 readiness and other factors.

RISK ASSESSMENT 

At this time, the Company believes its most reasonably likely worst case
scenario is a temporary disruption of service to its gas customers, including
the disruptions caused by key vendors on which the Company relies for its gas
deliveries. In particular, the Company believes that most of the gas movement
components can be manually controlled. The Company has been informed that our
major gas supplier will have staff standing by at the time of transition. The
Company is assessing the risk of these scenarios and is formulating contingency
plans, currently scheduled to be completed during the second quarter of 1999, to
mitigate the potential impact.

CONTINGENCY PLANS 

Contingency plans will be prepared so that the Company's critical business
processes can be expected to continue to function on January 1, 2000 and beyond.
The Company's contingency plans will be structured to address both remediation
of systems and their components and overall business operating risk. The work on
the contingency plan is focusing primarily on high priority items that affect
customer safety, continuation of service and revenue. These plans are intended
to mitigate both internal risks as well as potential risks in the supply chain
of the Company's suppliers and customers.

The Company's Year 2000 project is designed to provide corrective action with
respect to Year 2000 risks. If the plan is not successfully carried out in a
timely manner, or if unforeseen events occur, Year 2000 problems could have a
material adverse impact on the Company. Management does not expect such problems
to have such an effect on its financial position or results of operations.

LIQUIDITY AND CAPITAL RESOURCES

CONSOLIDATED

The Company obtains its common equity requirements, if any, through issuances of
its common stock, including the proceeds from its Automatic Dividend
Reinvestment Plan (DRP). In 1996, the DRP was amended to allow for the purchase
of shares on the open market. The Company can switch funding options once in any
three-month period. In September 1996, the Company implemented a one-million
share repurchase program, and through September 30, 1998, has repurchased
522,670 shares.

The Company provides the debt requirements for its unregulated companies, while
NJNG satisfies its debt needs by issuing short-term and long-term debt based
upon its own financial profile. In order to meet the working capital and
external debt financing requirements of the unregulated companies, as well as
its own working capital needs, the Company maintains committed credit facilities
totaling $135 million with a number of banks.

It is the Company's objective to maintain a consolidated capital structure that
reflects the different characteristics of each business segment and provides
adequate financial flexibility for accessing capital markets as required. Based
upon its existing mix of investments, it is the Company's goal to achieve a
common equity ratio of approximately 50%.

At September 30, the Company's consolidated capital structure was as follows:

NJNG

The seasonal nature of NJNG's operations creates large short-term cash
requirements, primarily to finance gas purchases and customer accounts
receivable. NJNG obtains working capital for these requirements, as well as for
the temporary financing of construction expenditures, sinking fund needs and
energy tax payments through the issuance of commercial paper and short-term bank
loans. To support the issuance of commercial paper, NJNG maintains committed
credit facilities totaling $90 million with a number of commercial banks.



                                                                              27

The level of construction expenditures results primarily from the need for
services, mains and meters to support NJNG's continued customer growth and
general system maintenance. Optional redemption activity included $38 million,
$7 million and $6 million of First Mortgage Bonds in 1998, 1997 and 1996,
respectively. In September 1998, NJNG received approval from the BPU to
establish a $60 million medium-term note program. On October 26, 1998, NJNG
redeemed its $20 million 7.72% Redeemable Preferred Stock. NJNG currently plans
to redeem its $20 million 10.1% Series S Bonds in 1999, subject to market and
other conditions.

</TABLE>

Cash flow, defined as net income adjusted for depreciation, amortization of
deferred charges and the change in deferred income taxes, represents the cash
generated from operations available for capital expenditures, dividends, working
capital and other requirements. Cash flow increased in 1998 and 1997 due
primarily to higher earnings and deferred tax benefits.

NJNG's external financing requirements are expected to be $50 million in 1999
and none in 2000. It is currently anticipated that they will be met through
additional issuances of short-term and long-term debt. The timing and mix of
these issuances will be geared toward maintaining a common equity ratio of
approximately 50%, which is consistent with maintaining its current short-term
and long-term credit ratings.

ENERGY HOLDINGS

Energy Holdings' capital requirements and financing activity for 1996 through
1998 were as follows:

</TABLE>

NJR Energy invested $2 million in 1998 for an equity interest in Capstone
Turbine Corporation, a developer of energy efficient gas-fired microturbine
units which produce electricity. Energy Holdings' cash flow in 1998 declined due
to lower earnings.

NJR Energy sold its interest in Market Hub Partners, L.P. for $9.1 million in
1997. Proceeds from the sale were used to reduce debt.

Energy Holdings does not currently expect any significant capital expenditures
or external financing requirements in 1999.

                                        ----------------------------------------
</TABLE>

Proceeds from asset sales have been used by the Company to reduce debt, while
the changes in cash flow in each year reflect the tax payments related to the
asset sales.

CR&R currently has 183 acres of undeveloped land and two, fully-occupied
buildings totaling 25,000 square-feet.

Capital expenditures were $1.6 million in 1998 in connection with the
construction of a 21,000 square-foot, build-to-suit office building, which is
supported by a ten-year lease.

CR&R's future capital expenditures will be limited to the fit-up of existing
tenant space and additional investments to preserve the value of its real estate
holdings.

FINANCIAL RISK MANAGEMENT

COMMODITY MARKET RISKS

The regulated and unregulated natural gas businesses of the Company and its
subsidiaries are subject to market risk due to fluctuations in the price of
natural gas. To hedge against such fluctuations, the Company and its
subsidiaries have entered into futures contracts, options agreements and
over-the-counter swap agreements. The Company's natural gas businesses are
conducted through three of its operating subsidiaries. First, NJNG is a
regulated utility whose recovery of gas costs is protected by the LGA, but to
further hedge against price fluctuations, utilizes futures and options through
its financial risk management program. Second, Energy Services has entered into
fixed-price sales contracts with wholesale customers for an aggregate of
approximately .7 Bcf of natural gas at prices ranging from $2.16 to $2.56 per
Mmbtu. Energy Services has also hedged its commitments to purchase natural gas
for the retail customers of Natural Energy and hedged purchases and sales of
storage gas. Finally, NJR Energy has entered into a long-term, fixed-price
contract to sell approximately 30.9 Bcf of natural gas to a gas marketing
company at prices ranging from $2.43 to $4.41 per Mmbtu.

Natural gas is a nationally traded commodity, and its prices are effectively
determined by the New York Mercantile Exchange (NYMEX) and over-the-counter
markets. The prices on the NYMEX and over-the-counter markets generally reflect
the national balance of natural gas supply and demand, but are also influenced
significantly from time to time by other events.

NJNG entered into futures contracts to buy and sell 8.1 Bcf of natural gas
through October 1999 at prices ranging from $1.995 to $2.72 per Mmbtu, and as of
September 30, 1998, NJNG had a deferred unrealized gain of approximately
$239,000 from these contracts.

As of September 30, 1998, Energy Services had entered into futures contracts to
buy 5.3 Bcf of natural gas through July 2000, at prices ranging from $1.885 to
$2.79 per Mmbtu, and had a deferred unrealized gain of $613,000 from these
futures contracts. Energy Services also entered into natural gas swap agreements
in order to hedge its risks on 5.1 Bcf of natural gas. As of September 30, 1998,
Energy Services had a deferred unrealized loss of approximately $162,000 from
these swap agreements.

NJR Energy has hedged both its price and physical delivery risks associated with
its long-term, fixed-price sales contract with a gas marketing company (the "Gas
Sale Contract"). To hedge its price risk, NJR Energy entered into two swap
agreements. Under the terms of these two swap agreements, NJR Energy will pay to
the counterparties the identical fixed price it receives from the gas marketing
company in exchange for the payment by the counterparties of an index price plus
a spread per Mmbtu for the total volumes under the Gas Sale Contract. The swap
agreements were effective as of November 1995. In order to hedge its physical
delivery risk, NJR Energy entered into a purchase contract with a second gas
marketing company for the identical volumes it is obligated to sell under the
Gas Sale Contract. NJR Energy has agreed to pay this second gas marketing
company the identical floating price it receives under the swap agreements
mentioned above.

To manage these instruments, the Company has well-defined risk management
policies and procedures, which include volumetric limits and monetary
guidelines.

All of the futures contracts, options and swap agreements described above are
held for hedging, rather than trading purposes. As of September 30, 1998, the
Company does not have any options outstanding. With respect to futures contracts
and swap agreements, the Company has performed a sensitivity analysis to
estimate its exposure to market risk arising from natural gas price fluctuations
using the net futures positions and the net swaps positions. Futures contracts
and swap agreements are substantially all settled at the NYMEX settlement date
and the related natural gas quantity is purchased or sold in the physical market
and, therefore, their notional values, which represent the absolute sum of all
outstanding natural gas futures contracts or swap agreements, as the case may
be, are not accurate measurements of risk to the Company from those futures
contracts or swap agreements. With respect to natural gas futures contracts as
of September 30, 1998, in the event of a hypothetical 10 percent change in
natural gas prices, the value of the Company's contracts would change by
approximately $1.2 million. With respect to natural gas swap agreements as of
September 30, 1998, in the event of a hypothetical 10 percent change in natural
gas prices, the value of such agreements would change by approximately $690,000
(in addition to the deferred unrealized loss of approximately $162,000 discussed
above). However, any such additional changes in value under the futures
contracts and the swap agreements would be substantially offset by a
corresponding change on the related underlying contracts that are being hedged.

INTEREST RATE RISK

NJNG has total variable rate debt of $97 million, of which $56 million has been
hedged by the purchase of a 6.5% interest rate cap through the year 2003.
According to the Company's sensitivity analysis, NJNG's annual interest rate
exposure on the $56 million, based on the difference between current average
rates and the 6.5% interest rate cap, is limited to $1.1 million, net of tax. If
interest rates were to change by 100 basis points on the remaining $41 million
of variable rate debt, NJNG's interest expense, net of tax, would change by
$242,000. The Company also has variable rate debt of $59.3 million, of which $15
million is hedged through an interest rate swap agreement which fixes interest
at 9.5%. According to the Company's sensitivity analysis, if interest rates were
to change by 100 basis points on the remaining $44.3 million, interest expense,
net of tax, would change by $261,000. Subsequent to the expiration of the
interest rate swap agreement in June 1999, a 100 basis point change would result
in an additional $89,000 annual change in interest expense, net of tax.

EFFECTS OF INFLATION

Although inflation rates have been low to moderate in recent years, any change
in price levels has an effect on operating results due to the capital intensive
and regulated nature of the Company's principal subsidiary. The Company attempts
to minimize the effects of inflation through cost control, productivity
improvements and regulatory actions where appropriate.

INFORMATION CONCERNING
FORWARD LOOKING STATEMENTS

Certain statements contained in this report (other than the financial statements
and other statements of historical fact), including statements as to management

Management's Discussion and Analysis under the captions "NJNG Operations - Gross

future developments and their potential effect upon the Company. There can be no
assurance that future developments will be in accordance with management's
expectations or that the effect of future developments on the Company will be
those anticipated by management.

The Company wishes to caution readers that the assumptions which form the basis
for forward-looking statements with respect to or that may impact financial
results and capital requirements for fiscal 1999 and thereafter include many
factors that are beyond the Company's ability to control or estimate precisely,
such as estimates of future market conditions and the behavior of other market

materially from estimates reflected in such forward-looking statements are
weather conditions, economic conditions, and demographic changes in NJNG's
service territory, fluctuations in energy commodity prices, conversion activity
and other marketing efforts, the conservation efforts of NJNG's customers, the
ability to extend certain fuel management contracts, unknown Year 2000 related
problems, the pace of deregulation of retail gas markets, competition for the
acquisition of gas, the regulatory and pricing policies of federal and state
regulatory agencies, legislative changes due to legislation in the New Jersey
Senate and the Assembly, the availability of Canada's reserves for export to the
United States and other regulatory changes. 

The Company does not, by including this statement, assume any obligation to
review or revise any particular forward-looking statement referenced herein in
light of future events.

INDEPENDENT AUDITORS' REPORT

To the Shareowners and Board of Directors of New Jersey Resources Corporation:

We have audited the accompanying consolidated balance sheets and consolidated
statements of capitalization of New Jersey Resources Corporation and its
subsidiaries (the Company) as of September 30, 1998 and 1997 and the related
consolidated statements of income, common stock equity and cash flows for each
of the three years in the period ended September 30, 1998. These financial
statements are the responsibility of the Company'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, such consolidated financial statements present fairly, in all
material respects, the financial position of the Company at September 30, 1998
and 1997 and the results of their operations and their cash flows for each of
the three years in the period ended September 30, 1998 in conformity with
generally accepted accounting principles.

We have also previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheets and consolidated statements of
capitalization as of September 30, 1996, 1995, 1994, and 1993, and the related
consolidated statements of income, common stock equity and cash flows for the
years ended September 30, 1995, 1994 and 1993 (none of which are presented
herein) and we expressed unqualified opinions on those consolidated financial
statements. In our opinion, the information set forth in the Selected Financial
Data for each of the six years in the period ended September 30, 1998 for the
Company, presented on page 22, is fairly stated in all material respects, in
relation to the consolidated financial statements from which it has been
derived.

NOTES TO CONSOLIDATED
FINANCIAL STATEMENTS                            New Jersey Resources Corporation


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF THE BUSINESS

New Jersey Resources Corporation (the Company) is an energy services holding
company providing retail and wholesale natural gas and related energy services
to customers from the Gulf Coast to New England. Its principal subsidiary, New
Jersey Natural Gas Company (NJNG), provides regulated natural gas and appliance
services in central and northern New Jersey and participates in the off-system
sales and capacity release markets. Other operating subsidiaries include New
Jersey Natural Energy Company (Natural Energy) and NJR Energy Services Company
(Energy Services), the Company's unregulated marketing and fuel and capacity
management subsidiaries, NJR Energy Corporation (NJR Energy), an investor in
energy-related ventures, and Commercial Realty and Resources Corp. (CR&R), a
commercial real estate developer.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and
its subsidiaries. Significant intercompany accounts and transactions have been
eliminated.

REGULATORY ACCOUNTING

NJNG maintains its accounts in accordance with the Uniform System of Accounts as
prescribed by the New Jersey Board of Public Utilities (BPU). As a result of the
ratemaking process, the accounting principles applied by NJNG differ in certain
respects from those applied by unregulated businesses.

UTILITY PLANT AND DEPRECIATION

Depreciation is computed on a straight-line basis for financial statement
purposes, using rates based on the estimated average lives of the various
classes of depreciable property. The composite rate of depreciation was 3.36% of
average depreciable property in 1998, 3.25% in 1997 and 3.12% in 1996. When
depreciable properties are retired, the original cost thereof, plus cost of
removal less salvage, is charged to accumulated depreciation.

UTILITY REVENUES

Customers are billed through monthly cycle billings on the basis of actual or
estimated usage. Revenues are based upon service rendered.

GAS PURCHASES

NJNG's tariff includes a Levelized Gas Adjustment (LGA) clause, which is
normally revised on an annual basis. Under this clause, NJNG projects its cost
of gas, net of supplier refunds and credits from non-firm sales and
transportation activities, over the subsequent 12 months and recovers the
excess, if any, of such projected costs over those included in its base rates
through levelized charges to customers. Any under- or over-recoveries are
deferred and reflected in the LGA clause in subsequent years.

STATE OF NEW JERSEY TAX REFORM

In January 1998, the utility gross receipts tax formula was replaced with a
state sales tax, a state income tax and a transitional energy facilities
assessment (TEFA). The TEFA will be gradually phased out between 1999 and 2002.
The new law requires that all energy providers in the state be subject to the
sales and state income taxes. Previously, non-utility providers of energy were
not subject to the gross receipts and franchise tax.

INCOME TAXES

Deferred income taxes are calculated in conformance with Statement of Financial
Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes" (SFAS 109)
(See Note 6: Income Taxes).

Investment tax credits have been deferred and are being amortized as a reduction
to the tax provision over the average lives of the related property.

CAPITALIZED INTEREST

The Company's capitalized interest totaled $714,000 in 1998, $1.3 million in
1997 and $1.4 million in 1996.

FINANCIAL INSTRUMENTS AND RISK MANAGEMENT

Gains and losses related to qualifying hedges of firm commitments or anticipated
transactions are deferred and recognized in income or as adjustments of carrying
amounts when the hedged transaction occurs (See Note 9: Financial Instruments
and Risk Management).

REGULATORY ASSETS

Regulatory Assets at September 30, 1998 and 1997 consist of the following items:

NEW ACCOUNTING STANDARDS

In June 1997, the Financial Accounting Standards Boards (FASB) issued SFAS No.
130 "Reporting Comprehensive Income" and SFAS No. 131 "Disclosure About Segments
of an Enterprise and Related Information." In February 1998, the FASB also
issued SFAS No. 132 "Employers' Disclosures about Pensions and Other
Postretirement Benefits." These statements must be adopted by fiscal 1999. It is
management's opinion that these statements will not have a material effect on
either its financial condition or results of operations. In June 1998, the FASB
issued SFAS No. 133 "Accounting for Derivative Investments and Hedging
Activities," which must be adopted by the quarter ended December 31, 1999. The
Company is currently evaluating the effects of SFAS No. 133 on its financial
condition and results of operations, which will vary based on the Company's use
of derivative instruments at the time of adoption.

RECLASSIFICATIONS 

Certain prior year amounts have been reclassified to conform to the current year
reporting.

USE OF ESTIMATES

The consolidated financial statements of the Company include estimates and
assumptions of certain assets, liabilities, revenues and expenses and the
disclosure of certain contingent assets and liabilities. Actual future results
may differ from such estimates.

2. COMMON STOCK

At September 30, 1998, there were 1,238,585 shares reserved for issuance under
the Company's Automatic Dividend Reinvestment, Employee Stock Ownership and
Retirement Savings Plans.

A total of 750,000 shares are reserved for issuance to employees under the
Long-Term Incentive Compensation Plan (the Plan) at the discretion of the Board
of Directors. At September 30, 1998, there were 352,967 shares remaining for
issuance or grant under the Plan. The Company issued 22,461 shares in 1997 with
a related annual expense of approximately $224,000, which vest over a three-year
period and are subject to the Company achieving certain performance targets.

All options granted under the Plan have been non-qualified stock options. They
give a right to purchase the Company's common stock at prices no less than the
closing price on the date of grant. Generally no option can be exercised before
one year or more than 10 years from the date of each grant.

A total of 175,000 shares are reserved for issuance to outside directors under
the Restricted Stock and Stock Option Program for Outside Directors (the
Program). Under the Program, each director received an award of 200 shares of
restricted stock which vests over four years. Each director is also granted
5,000 options upon joining the Board. A Supplemental Stock Option Program
(Supplemental Program) was approved by the Board of Directors, effective October
1, 1998. The Supplemental Program provides that each director receives an annual
grant of 1,500 options. All other terms of the Program remain the same. In 1998,
200 shares were issued and none were forfeited. At September 30, 1998, there
were 60,750 shares remaining for issuance or grant under the Program, including
the Supplemental Program. All options granted under the Program allow for
purchase of common stock at prices equal to the closing price on the date of
grant, and no option can be exercised before one year or more than 10 years from
the date of each grant.

In 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based Compensation"
(SFAS 123). As permitted by SFAS 123, the Company will continue to apply
Accounting Principles Board Opinion No. 25 and its related interpretations in
accounting for its stock-based plans and provide the pro forma disclosures
required by SFAS 123. No compensation expense has been recognized for its
stock-based plans except for performance-based awards. If compensation expense
had been determined based on the fair value of stock options at the date of
grant consistent with the methodology of SFAS 123, the Company's net income
would have been reduced by approximately $171,000 ($.01 EPS - Basic and Diluted)
in 1998, $249,000 ($.02 EPS - Basic, $.01 EPS - Diluted) in 1997, and $47,000
($.01 EPS - Basic and no impact to Diluted) in 1996.

The following table summarizes the stock option activity for the past three
years:

The Company has adopted SFAS No. 128 "Earnings Per Share" which establishes
standards for computing and presenting basic and diluted earnings per share
(EPS). SFAS 128 requires that all prior data presented be restated. The
incremental shares, which relate to stock options and restricted stock, using
the treasury stock method, that were required for inclusion in the denominator
for the diluted EPS calculation were 96,205 and 50,540 for 1998 and 1997,
respectively. The numerator for both the basic and diluted calculations was net
income. The impact was a two-cent and one-cent dilutive effect for 1998 and
1997, respectively.

In September 1996, the Board of Directors authorized the repurchase of up to one
million of the Company's common shares. As of September 30, 1998, the Company
has repurchased 522,670 shares of its common stock at a cost of $16.7 million.

3. REDEEMABLE PREFERRED STOCK

The $20 million 7.72% series was redeemed in October 1998 at a price of $101.72
per share.

Preferred stockholders are entitled to one vote per share on all NJNG matters
and have priority as to dividends. NJNG's certificate of incorporation prohibits
the distribution of common stock dividends unless NJNG is in compliance with all
its provisions. In addition, whenever preferred dividends are in arrears in an
amount equal to four quarterly dividends, preferred stockholders may elect a
number of directors necessary to constitute one less than a majority of NJNG's
Board of Directors, until such dividends are paid in full.

In July 1996, the Board of Directors adopted a shareholder rights plan that
provides for the distribution of one right for each share of common stock
outstanding on or after August 15, 1996. Each right entitles its holder to
purchase 1/1000 of one share of the Series A Stock (as defined below), at an
exercise price of $55.

The rights plan provides that after a person or group acquires 10% or more of
the Company's common stock, each of the rights, except for those held by the 10%
holder, which become void once the holder reaches the 10% threshold, becomes the
right to acquire shares of the Company's common stock having a market value
equal to twice the exercise price. If a person or group acquires at least 10%,
but less than 50%, the Board of Directors may exchange each right for one share
of the Company's common stock. The rights may be redeemed for $.01 per right at
any time prior to the first public announcement or communication to the Company
that a person or group has crossed the 10% threshold.

The Company has 400,000 shares of authorized and unissued $100 par value
preferred stock. The Company has created and reserved for issuance 50,000 shares
of Series A Junior Participating Cumulative Preferred Stock (Series A Stock) in
connection with the adoption of the shareholder rights plan.

4. LONG-TERM DEBT, DIVIDENDS AND RETAINED EARNINGS RESTRICTIONS

Annual redemption requirements for the next five years are as follows: 1999, $2
million; 2000, $61.3 million; 2001, $2.3 million; 2002, $27.3 million and 2003,
$2.4 million.

NJNG's mortgage secures its First Mortgage Bonds and represents a lien on
substantially all its property, including gas supply contracts. Certain
indentures supplemental to the mortgage include restrictions as to cash
dividends and other distributions on NJNG's common stock, which restrictions
apply so long as certain series of First Mortgage Bonds are outstanding. Under
the most restrictive provision, approximately $54.1 million of NJNG's retained
earnings was available for such purposes at September 30, 1998.

NJNG has entered into loan agreements with the New Jersey Economic Development
Authority (the Authority) in which the Authority issues bonds to the public. To
secure its loans from the Authority, NJNG issues First Mortgage Bonds with
interest rates and maturity dates identical to the Authority's Bonds.

In April 1998, NJNG entered into a loan agreement whereby the Authority loaned
NJNG the proceeds from its $18 million Natural Gas Facilities Revenue Bonds,
Series 1998C (the EDA Bonds). The rates of interest on the EDA Bonds are
variable, currently set at a weekly mode, and may be changed by NJNG to daily,
weekly, flexible or long-term interest rate modes, not to exceed 10% per annum.
The EDA Bonds mature on April 1, 2033. The proceeds from the EDA Bonds were
deposited into a project construction fund. NJNG may obtain such funds in
reimbursement of its qualified expenditures relating to the project upon
delivering an equivalent amount of its Adjustable Rate Series GG First Mortgage
Bonds (Series GG Bonds) to the indenture trustee. In April 1998, NJNG drew down
$2 million from the construction fund and issued $2 million of its Series GG
Bonds.

In January 1998, NJNG issued variable rate Series EE and Series FF Bonds for
$9.5 million and $15 million, respectively. The proceeds were used to redeem the
$9.5 million 7.05% Series T and the $15 million 7.25% Series U Bonds on March 1,
1998.

In October 1997, NJNG issued variable rate Series DD Bonds for $13.5 million and
utilized the proceeds to redeem its $13.5 million 9% Series Q Bonds in December
1997.

NJNG has total variable rate debt of $97 million, of which $56 million has been
hedged by the purchase of a 6.5% interest rate cap through the year 2003.

In December 1995, the BPU approved NJNG's petition to enter into a master-lease
agreement for its headquarters building for a 25.5 year term with two five-year
renewal options. The present value of the agreement's minimum lease payments is
reflected as both a capital lease and a capital lease obligation, which are


                                                                              37

included in Utility Plant and Long-Term Debt, respectively, in the Consolidated
Balance Sheets. In accordance with its ratemaking treatment, NJNG records rent
expense as if the lease was an operating lease. Minimum annual lease payments
are $2.3 million in 1999, $2.4 million in 2000, and $2.6 million in 2001 through
2003, with $58.1 million over the remaining term of the lease. Approximately 21%
of the building, representing approximately $100,000 of minimum annual lease
payments through 1999, is presently subleased to other tenants.

The Company has six committed revolving credit agreements totaling $135 million,
which provide for bank loans at negotiable rates at or below the prime rate. At
September 30, 1998, a total of $59.3 million was outstanding under these
agreements, all of which matures in 2000.

The Company has one interest rate swap agreement, having a notional amount of
$15 million, to eliminate the impact of changes in interest rates on a portion
of its floating rate long-term debt. The agreement effectively fixes the
Company's interest rate on $15 million of its floating rate revolving credit
facilities at 9.5% through June 1999. In the event of nonperformance by the
counterparty, the Company's interest cost on $15 million of long-term debt would
revert to a floating rate. However, the Company does not anticipate
nonperformance by the counterparty.

The Company's remaining long-term debt outstanding under revolving credit
agreements at September 30, 1998 and 1997 totaled $44.3 million and $25 million,
with weighted average interest rates of 6.1% and 5.9%, respectively.

5. SHORT-TERM DEBT AND CREDIT FACILITIES 

Committed credit facilities of NJNG support the issuance of commercial paper and
provide for bank loans at negotiable rates at or below the prime rate. These
credit facilities total $90 million and require commitment fees on the unused
amounts. A comparison of pertinent data follows:

6. INCOME TAXES

The Company's federal income tax returns have been examined by the Internal
Revenue Service (IRS) through 1993 and all significant matters have been
settled. The IRS has substantially completed its examination of the 1995 and
1994 tax returns and the Company does not anticipate any significant issues.

Income tax expense differs from the amount computed by applying the statutory
federal income tax rate of 35% to pre-tax income for the following reasons:

7. REGULATORY ISSUES

NJNG's Weather-Normalization Clause (WNC) provides for a revenue adjustment if
the weather varies by more than one-half of 1% from the 20-year average, or
normal, weather. The accumulated adjustment from one heating season (i.e.,
October - May) is billed or credited to customers in subsequent years.

In January 1998, the BPU approved a 3.5% LGA price increase, which included
updates to NJNG's Gas Cost Recovery, WNC, Remediation Rider (RA) and Demand Side
Management Adjustment clause factors.

In September 1998, the BPU approved a comprehensive agreement which provides all
NJNG customers the option to choose a natural gas supplier as early as January
1, 1999, modification and extension of the existing margin-sharing formulas for
the off-system and capacity release programs and a new margin-sharing incentive
related to permanent cost reductions of NJNG's gas supply portfolio. The BPU
also approved an additional 3.5% price increase designed to recover $34.9
million of deferred gas costs from both sales and transportation customers. All
of these provisions are effective for the period from October 1, 1998 to
December 31, 2001.


8. EMPLOYEE BENEFIT PLANS

PENSION PLANS

The Company has two trusteed, noncontributory defined benefit retirement plans
covering all regular, full-time employees with more than one year of service.
Plan benefits are based on years of service and average compensation during the
last five years of employment. The Company makes annual contributions to the
plans consistent with the funding requirements of federal law and regulations.


The components of the net pension cost are as follows:

OTHER POSTRETIREMENT BENEFITS

Effective October 1, 1993, the Company adopted SFAS No. 106 "Employers'
Accounting for Postretirement Benefits Other Than Pensions," which requires an
accrual method of accounting for postretirement benefits, similar to that in
effect for pension plans. Previously, certain health care and life insurance
benefits were charged to expense when paid. Under the accrual method, the cost
of providing postretirement benefits will be recognized over the employee's
service period. The Company's transition obligation associated with SFAS 106 was
$8.6 million, which is being amortized over 20 years, and its annual expense has


                                                                              39

increased from approximately $400,000 to $2.2 million, of which over 95% relates
to NJNG. 

Effective October 1, 1998, the BPU approved the recovery of an additional
$945,000 of annual OPEB costs as well as recovery of $4.9 million of deferred
costs over the next 15 years, which is included in Regulatory Assets in the
Consolidated Balance Sheets.

A reconciliation of the accumulated postretirement benefit obligation (APBO) to
the amounts recognized in the Consolidated Balance Sheets is presented below:

The assumed health care cost trend rate used in measuring the APBO as of
September 30, 1998 was 10%, declining by 1% each year until attaining an
ultimate level of 5.5% in 2003, and then remaining constant thereafter for
participants under age 65. For participants age 65 and older the trend rate was
8% in 1998, declining to 5.5% in 2003, and then remaining constant thereafter. A
1% increase in the trend rates would increase the APBO as of September 30, 1998,
by $3.1 million and would increase the annual service and interest costs by
$369,000. The assumed discount rate used in determining the APBO was 6.25% and
7.75% at September 30, 1998 and 1997, respectively.

9. FINANCIAL INSTRUMENTS AND RISK MANAGEMENT 

Energy Services and Natural Energy enter into fixed-price contracts to sell
natural gas. In order to hedge these contracts, as of September 30, 1998, Energy
Services entered into futures contracts to buy 5.26 Bcf of natural gas through
July 2000 at prices ranging from $1.885 to $2.79 per MMbtu and had a deferred
unrealized gain of $613,000 related to these contracts. Energy Services also
entered into natural gas swap agreements in order to hedge its risk for 5.1 Bcf
of natural gas and as of September 30, 1998 had a deferred unrealized loss of
approximately $162,000 related to these agreements.

As part of its Financial Risk Management program, NJNG entered into futures
contracts to buy and sell 8.1 Bcf of natural gas through October 1999 at prices
ranging from $1.995 to $2.72 per MMbtu and had a deferred unrealized gain of
approximately $239,000 related to these contracts.

In March 1992, NJR Energy entered into long-term, fixed-price contracts to sell
natural gas to a gas marketing company. In October 1994, in conjunction with a
shift in capital allocation policy, NJR Energy entered into a swap agreement
which hedged its risk for sales volumes under the contract which were in excess
of the estimated production from natural gas reserves owned at that time. NJR
Energy has sold its natural gas reserves pursuant to a plan to exit the oil and
gas production business. In order to hedge its risk for sales volumes under such
contract that would have otherwise been fulfilled by its producing reserve base,
NJR Energy entered into a second swap agreement in June 1995. In connection with
the second swap, NJR Energy received $3.3 million, which is included in Deferred
Revenue and is being amortized to income over the 15-year life of the agreement.
Under the terms of the swap agreements, NJR Energy will pay to the
counterparties the identical fixed price it receives from the gas marketing
company (the fixed price) in exchange for the payment by the counterparties of
an index price plus a spread per MMbtu (the floating price) for the total
volumes under the gas sales contract. The swap agreements were effective as of
November 1995, and will expire on the same date as the underlying gas sales
contract. As of September 30, 1998, NJR Energy would have to pay approximately
$27.5 million to terminate these swap agreements.

In order to secure the physical gas supply to meet the delivery requirements
under its gas sales contracts, NJR Energy entered into a long-term purchase
contract effective November 1995 with a second gas marketing company for the
identical volumes it is obligated to sell under the above mentioned gas sales
contract. NJR Energy has agreed to pay the supplier the identical floating price
it is receiving under the swap agreements. In conjunction with this contract,
NJR Energy received $1.9 million, which is included in Deferred Revenue and is
being amortized to income over the life of the agreement.

                                                New Jersey Resources Corporation



The net result of the above swap agreements and purchase contract is that NJR
Energy has hedged both its price and volume risk associated with its long-term,
fixed-price sales contract. The respective obligations of NJR Energy and the
counterparties under the swap agreements are guaranteed, subject to a maximum
amount, by the Company and the respective counterparties' parent corporations.
In the event of nonperformance by the counterparties and their parent
corporations, NJR Energy's financial results would be impacted by the
difference, if any, between the fixed price it is receiving under the gas sales
contract compared with the floating price it is paying under the purchase
contract. However, the Company does not anticipate nonperformance by the
counterparties.

The fair value of cash and temporary investments, accounts receivable, accounts
payable, commercial paper and borrowings under revolving credit facilities are
estimated to equal their carrying amounts due to the short maturity of those
instruments. The estimated fair value of long-term debt is based on quoted
market prices for similar issues and the fair value of interest rate swap
agreements is based on the estimated amount the Company would receive or pay to
terminate the agreements. The carrying amount of long-term debt was $297.1
million and $259.8 million, with a fair market value of $311.8 million and
$266.3 million at September 30, 1998 and 1997, respectively. The Company would
have to pay approximately $756,000 and $1 million to terminate its interest rate
swap agreement at September 30, 1998 and 1997, respectively.

10. COMMITMENTS AND CONTINGENT LIABILITIES 

NJNG has entered into long-term contracts for the supply, storage and delivery
of natural gas with pipeline companies that expire at various dates through
2012. These contracts include fixed charges of approximately $104 million per
year, which are recovered through the LGA.

Capital expenditures are estimated at $54.7 million and $50.5 million in fiscal
1999 and 2000, respectively, and consist primarily of NJNG's construction
program to support its customer growth and maintain its distribution system.

NJNG is participating in environmental investigations and the preparation of
proposals for remedial action at 11 former manufactured gas plant (MGP) sites.
Through the RA approved by the BPU, NJNG is recovering expenditures incurred
through June 1997 over a seven-year period. Costs incurred subsequent to June
30, 1997 will be reviewed annually and, subject to BPU approval, recovered over
seven-year periods. In 1996, NJNG, with the assistance of an outside consulting
firm, completed an environmental review of the sites, including a review of its
potential liability for investigation and remedial action. On the basis of such
review, NJNG estimates that, exclusive of any insurance recoveries, total future
expenditures to remediate and monitor known MGP sites will range from $27.5
million to $60 million. NJNG's estimates of these liabilities are based upon
currently available facts, existing technology and presently enacted laws and
regulations. Where available information is sufficient to estimate the amount of
the liability, it is NJNG's policy to accrue the full amount of such estimate.
Where the information is sufficient only to establish a range of probable
liability and no point within the range is more likely than any other, it is
NJNG's policy to accrue the lower end of the range. Accordingly, NJNG has
recorded an accrued liability and corresponding regulatory asset of $27.5
million. The actual costs to be incurred by NJNG are dependent upon several
factors, including final determination of remedial action, changing technologies
and governmental regulations, the ultimate ability of other responsible parties
to pay and any insurance recoveries. NJNG will continue to seek recovery of such
costs through the RA.

NJNR Pipeline Company, a wholly-owned subsidiary of NJR Energy, owns a 2.8%
equity interest in the Iroquois Gas Transmission System, L.P. (Iroquois) which
has constructed and is operating a 375-mile, natural gas pipeline from the
Canadian border to Long Island. The Company has guaranteed a pro-rata share of a
debt service letter of credit obtained by Iroquois which totaled $1 million at
September 30, 1998. The Company does not expect to incur any cash requirements
under the guarantee.

The Company is a party to various claims, legal actions and complaints arising
in the ordinary course of business and other investigations. In management's
opinion, the ultimate disposition of these matters will not have a material
adverse effect on either its financial condition or results of operations.
