               PIEDMONT NATURAL GAS COMPANY, INC. AND SUBSIDIARIES
        Notes to Condensed Consolidated Financial Statements (Unaudited)

1.       The condensed consolidated financial statements have not been audited
         by independent auditors. These financial statements should be read in
         conjunction with the Notes to Consolidated Financial Statements
         included in the Company's 1997 Annual Report.

2.       In the opinion of the Company, the accompanying unaudited condensed
         consolidated financial statements include all adjustments (consisting
         only of normal recurring accruals) necessary to present fairly the
         financial position of the Company at July 31, 1998, and October 31,
         1997, and the results of its operations and its cash flows for the
         three months, nine months and twelve months ended July 31, 1998 and
         1997.

3.       The Company's business is seasonal in nature. The results of operations
         for the three-month and nine-month periods ended July 31, 1998, are not
         necessarily indicative of the results to be expected for the full year.

4.       Basic earnings per share are computed based on the weighted average
         number of shares of Common Stock outstanding during each period.
         Effective January 1, 1998, the Company adopted Statement of Financial
         Accounting Standards No. 128, "Earnings Per Share". A reconciliation of
         basic and diluted earnings per share is presented below:

Item 2.  Management's Discussion and Analysis of Financial
Condition and Results of Operations

Financial Condition

The Company finances its current cash requirements through internally generated
cash, the issuance of new common stock through dividend reinvestment and
employee stock purchase plans and committed bank lines of credit totaling $75
million. In addition, the Company sells common stock and long-term debt to cover
cash requirements when market or other conditions warrant such long-term
financing.

Because of the seasonal nature of the natural gas business, a substantial
portion of the annual earnings are realized in the winter period, which is the
first six months of the fiscal year. Injections of natural gas into storage
occur during periods of warm weather (principally April 1 through October 31)
for withdrawal from storage during periods of cold weather (principally November
1 through March 31). Due to this seasonality and the demand for gas during the
winter season, inventory of stored gas decreased and receivables increased from
October 31, 1997, to July 31, 1998.

The Company has a substantial capital expansion program to sustain its
approximately 5% current annual growth in customer base. The capital expansion
program is dependent on the continuing ability to generate the necessary funds
required for this growth. Utility construction expenditures for the three, nine
and twelve months ended July 31, 1998, were $24.5 million, $59.2 million and
$81.2 million, respectively, compared with $26.7 million, $71.5 million and
$97.7 million, respectively, for similar prior periods.

At July 31, 1998, capitalization consisted of long-term debt of 44% and common
equity of 56%.

Results of Operations

Margin for the three months ended July 31, 1998, decreased $1.6 million compared
with the same period last year even though increased volumes of natural gas,
including secondary market transactions, were sold or transported to industrial
customers. A lower margin is earned on activity with these customers compared
with other classes of customers. Delivered volumes (system throughput) for the
current three-month period decreased from the similar prior period by 117,000
dekatherms, a less than 1% decrease. Volumes from secondary market sales
increased over the similar prior period by 2 million dekatherms, a 61% increase.
Weather for the three months ended July 31, 1998, was 75% warmer than the
similar prior period; however, weather does not significantly impact margin for
the three months ended July 31.

                                       -6-

Margin for the nine months ended July 31, 1998, increased $7.9 million compared
with the similar prior period due to customer growth and increased volumes of
gas sold or transported, including secondary market transactions. The current
period includes rate increases in Tennessee with only partial inclusion of the
rate increase in the similar prior period as the increases were effective
January 1, 1997. System throughput for the current nine months increased over
the similar prior period by 5.4 million dekatherms, a 5% increase. Volumes from
secondary market sales increased over the similar prior period by 9.1 million
dekatherms, a 51% increase. Weather for the nine months ended July 31, 1998, was
1% warmer than the similar prior period. The weather normalization adjustment
(WNA), in effect from November 1 through March 31, increased operating revenues
by $5 million in the current nine-month period, compared with an increase of
$10.6 million for the similar prior period.

Margin for the twelve months ended July 31, 1998, increased $9.3 million
compared with the similar prior period due to regulatory-approved changes and
increased volumes of gas sold or transported, including secondary market
transactions. The current twelve month period includes higher rates from general
rate cases as compared to partial inclusion in the similar prior period. System
throughput for the current twelve months increased over the similar prior period
by 5.5 million dekatherms, a 4% increase. Volumes from secondary market sales
increased over the similar prior period by 9.5 million dekatherms, a 39%
increase. Weather for the twelve months ended July 31, 1998, was less than 1%
warmer than the similar prior period. The WNA increased operating revenues by $5
million in the current twelve-month period, compared with an increase of $10.6
million for the similar prior period.

The Company's rate schedules include gas cost recovery provisions that permit
the recovery of prudently incurred gas costs. Annual prudence reviews covering a
historical twelve-month period are required in North Carolina and South Carolina
but are not required in Tennessee. Through Purchased Gas Adjustment (PGA)
procedures, rates in all three states are revised periodically without formal
rate proceedings to reflect changes in the cost of gas. Charges to cost of gas
are based on the amount recoverable under approved rate schedules. The net of
any over- or under-recoveries of gas costs is charged or credited to cost of gas
and included in refunds due customers in the financial statements.

Operations and maintenance expenses for the three months, nine months and twelve
months ended July 31, 1998, decreased from similar prior periods primarily due
to decreases in advertising, office supplies, outside consultants and employee
benefit costs, partially offset by increases in outside labor. Compared with the
similar prior period, expenses for the three months decreased for

                                       -7-

payroll and the provision for uncollectibles. For the nine months, expenses for
rents and leases and payroll also decreased. And for the twelve months, expenses
for rents and leases decreased, partially offset by an increase in payroll. Such
results reflect the Company's plan to reduce overall operating expenses
implemented during fiscal 1997.

Depreciation expense for the three months, nine months and twelve months ended
July 31, 1998, increased over similar prior periods due to the growth of plant
in service.

General taxes for the three months, nine months and twelve months ended July 31,
1998, decreased from similar prior periods. Decreases for the nine-month and
twelve-month periods were primarily due to decreases in gross receipts taxes and
payroll taxes, partially offset by increases in property taxes and franchise
taxes. The decrease in the three-month period was primarily due to a decrease in
payroll taxes, partially offset by an increase in property taxes.

Other income for the three months and nine months ended July 31, 1998, decreased
from similar prior periods primarily due to decreases in earnings from energy
marketing services. The decrease in the three-month period was also due to a
decrease in earnings from jobbing operations and non-regulated gas activities,
partially offset by an increase in earnings from merchandise operations. The
nine-month period was also decreased due to decreases in earnings from propane
operations and merchandise activities. Other income for the twelve months ended
July 31, 1998, increased over the similar prior period due to increases in
earnings from propane operations, jobbing activities, interest income and income
from the performance incentive plan in Tennessee. The increase in the
twelve-month period was partially offset by decreases in earnings from energy
marketing services and merchandise operations.

Utility interest charges for the three months, nine months and the twelve months
ended July 31, 1998, decreased from similar prior periods primarily due to
decreases in interest on long-term debt due to lower balances outstanding. The
nine-month and twelve-month periods were also decreased by decreases in interest
on short-term debt due to lower balances outstanding, but at slightly higher
interest rates. The decreases in the nine-month and twelve-month periods were
partially offset by increases in interest on refunds due customers due to higher
balances outstanding.

Year 2000 Issues

The Company has initiated an enterprise project to address the Year 2000 issue
for all technology hardware and software and all interfaces with customers and
suppliers. Based upon comprehensive

                                       -8-

assessments, a master plan has been developed that outlines time and cost
estimates for replacement or remediation, including internal and external
resources. Replacement of the Company's core financial systems with Year 2000
compliant client-server software is in process with an anticipated ready date of
November 1998. The replacement of the human resources/payroll system is in
process with an expected ready date of December 1998. The capital costs of the
core financial and human resources/payroll systems, including infrastructure
costs, are expected to be $11 million, of which $4.4 million has already been
incurred. Mainframe applications are also included in the master plan and have
undergone or are currently undergoing remediation at an expected cost before
testing of $900,000.

The Company's telecommunications and embedded systems are currently being
assessed. The Company plans to upgrade or replace mission-critical components of
the telecommunications and embedded systems. Pending completion of this
assessment, the Company cannot as yet estimate these costs. Overall, the master
plan is to have all mission-critical systems Year 2000 ready by December 31,
1998. The remaining support systems and non-critical embedded systems, as well
as final testing, will be completed before December 31, 1999.

The Company has initiated a formal communications process with critical
suppliers, vendors and large-volume customers through use of a Year 2000 survey
to determine the extent to which those companies are addressing their Year 2000
compliance. The Company is continuing to evaluate their responses and is making
follow-up inquiries to those who have not yet responded. Following further
analysis, the Company will take the appropriate actions necessary to mitigate
any anticipated negative impacts to the Company. At this time, the Company does
not expect a major impact from non-compliant Year 2000 suppliers, vendors or
customers.

The Company expects that all necessary systems will be Year 2000 ready by
December 31, 1999. As progress is made, the master plan is continually revised
to address the risks of the Year 2000 issue, including contingency plans as
appropriate to address "worst case" scenarios. The total capital and operating
costs to be Year 2000 ready, including assessment, replacement and remediation,
are estimated to be $21 million. Such costs are not expected to significantly
impact the Company's financial position or results of operations.

Item 5.  Other Information

South Carolina Rate Proceedings

In November 1995, the Public Service Commission of South Carolina (PSCSC)
approved a general increase in the Company's rates of approximately $7.8 million
annually. The rate increase was based on a return on common equity of 12.5%. The
South Carolina Consumer Advocate appealed the order of the PSCSC. On August 31,
1998, the South Carolina Supreme Court ruled that the PSCSC had failed to set
forth sufficient findings of fact to support the 12.5% return. The matter was
remanded to the PSCSC for further proceedings. The Company believes there is
sufficient evidence in the record to support the allowed return and that the
return will ultimately be upheld once the PSCSC sets forth the findings of fact
upon which it based its decision. The Court also ruled that the PSCSC erred in
permitting the Company to recover certain demand side management costs because
the Company did not provide a cost benefit analysis with respect to these costs.
The Company does not believe this ruling will have an adverse effect on the
Company since these costs will be placed in a deferred account for recovery in a
subsequent rate proceeding when the PSCSC can examine the benefits relating to
these costs.

Tennessee Rate Proceedings

As previously reported, the Tennessee Regulatory Authority (TRA), in a general
rate case proceeding, approved in December 1996 an increase in the Company's
margin in Tennessee, effective January 1, 1997, in the amount of $4.4 million
annually. The TRA's decision was confirmed by a written decision in February
1997. The Tennessee Consumer Advocate filed several pleadings with the TRA
arguing, among other things, that the Company was not entitled to recover the
increased rates prior to the date of the TRA's February order. All parties in
this proceeding, including the Company, petitioned the TRA to reconsider its
February order. In June 1997, the TRA issued an order denying all motions and
upholding its previous orders. In August 1997, the Consumer Advocate petitioned
the Court of Appeals for a review of the TRA's orders. On July 1, 1998, the
Court of Appeals affirmed the TRA's February order.

SouthStar Energy Services Company, LLC and Resource Energy Services
Company, LLC

On July 15, 1998, the Company, along with AGL Resources, Inc., and Dynegy, Inc.,
announced the formation, effective July 1, 1998, of SouthStar Energy Services,
LLC (SouthStar), which will offer a combination of unregulated energy products
and services to industrial, commercial and residential customers in the
southeast

                                      -11-

United States. The products and services will include natural gas, electricity,
fuel oil and propane, along with related retail services. The Company's
investment in the venture is through its wholly owned subsidiary, Piedmont
Energy Company.

SouthStar will initially market energy products and services to industrial and
commercial customers throughout the southeast and will offer residential and
small business energy services to customers within Georgia as that market opens
to competition in November 1998. As other states open their markets to
competition, SouthStar will expand its residential and small business services
to these areas.

Effective April 30, 1998, Piedmont Energy Company sold its 51% interest in
Resource Energy Services Company, LLC (Resource). Piedmont Energy Company
subsequently purchased certain assets from Resource and transferred those assets
to SouthStar. The net result of the loss on the sale of the interest in Resource
and the transfer of assets to SouthStar was immaterial.

Expansion of Services

On June 17, 1998, the Company filed a petition with the North Carolina Utilities
Commission (NCUC) for approval of an expansion project that would extend natural
gas service to the counties of Avery, Mitchell and Yancey which are currently
without natural gas service. The Company also requested authority to use $26.3
million in expansion fund money to partially fund the estimated cost of the
project of $31.9 million. Hearings are scheduled to begin in September. The
outcome of this proceeding cannot be determined at this time.
