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

1.     Independent auditors have not audited the condensed consolidated
       financial statements. These financial statements should be read in
       conjunction with the Notes to Consolidated Financial Statements included
       in our 1998 Annual Report.

2.     In our opinion, the unaudited condensed consolidated financial statements
       include all normal recurring adjustments necessary for a fair statement
       of financial position at April 30, 1999, and October 31, 1998, and the
       results of operations and cash flows for the three months, six months and
       twelve months ended April 30, 1999 and 1998.

       We make estimates and assumptions when preparing financial statements.
       Those estimates and assumptions affect the reported amounts of assets and
       liabilities and the disclosure of contingent assets and liabilities at
       the date of the financial statements and the reported amounts of revenues
       and expenses during the reporting period. Actual results could differ
       from our estimates.

3.     Our business is seasonal in nature. The results of operations for the
       three-month and six-month periods ended April 30, 1999, do not
       necessarily reflect the results to be expected for the full year.

4.     Basic earnings per share are computed by dividing net income by the
       weighted average number of shares of common stock outstanding for the
       period. Diluted earnings per share reflect the potential dilution that
       could occur when common stock equivalents are added to common shares
       outstanding. Shares that may be issued under the long-term incentive plan
       are our only common stock equivalents. A reconciliation of basic and
       diluted earnings per share is shown below:

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

Forward-Looking Statements

Our discussion contains forward-looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995. Statements concerning plans,
objectives, proposed capital expenditures and future events or performance are
some of the items included in forward-looking statements. Our statements reflect
our current expectations and involve a number of risks and uncertainties.
Although we believe that our expectations are based on reasonable assumptions,
we can give no assurances that these expectations will be achieved. Important
factors that could cause actual results to differ include:

         -        regulatory issues, including those that affect allowed rates
                  of return, rate structure and financings,
         -        industrial, commercial and residential growth in the service
                  territories,
         -        deregulation, unanticipated impacts of restructuring and
                  increased competition in the energy industry,
         -        the potential loss of large-volume industrial customers due to
                  bypass or the shift by such customers to special competitive
                  contracts at lower per unit margins,
         -        economic and capital market conditions,
         -        ability to meet internal performance goals,
         -        the capital intensive nature of our business, including
                  development project delays or changes in project costs,
         -        changes in the availability and price of natural gas,
         -        changes in demographic patterns and weather conditions,
         -        changes in environmental requirements and cost of compliance
                  and
         -        unexpected problems related to our internal Year 2000
                  initiative as well as potential adverse consequences related
                  to third-party Year 2000 compliance.

Financial Condition

We finance current cash requirements through operating cash flows, the issuance
of new common stock through dividend reinvestment and employee stock purchase
plans and short-term borrowings. Various banks provide lines of credit totaling
$75 million for these direct short-term borrowings. We sell common stock and
long-term debt to cover cash requirements when market or other conditions
require such long-term financing.

Our natural gas business is seasonal in nature causing fluctuations in balances
in accounts receivable from customers, inventories of stored natural gas and
accounts payable to suppliers. From April 1 to October 31, we build up natural
gas inventories by injecting gas into storage for sale in the colder months.
Inventory of stored gas and accounts payable decreased and accounts receivable
increased from October 31, 1998, to April 30, 1999, due to this seasonality and
the

                                       -6-
<PAGE>   7


demand for gas during the winter season. Most of our annual earnings are
realized in the winter period, which is the first five months of our fiscal
year.

We have a substantial capital expansion program for construction of distribution
facilities, purchase of equipment and other general improvements funded through
sources noted above and short-term debt. The capital expansion program supports
our approximately 5% current annual growth in customer base. Utility
construction expenditures for the three months ended April 30, 1999, were $24.5
million, compared with $17.7 million for the same period in 1998. Utility
construction expenditures for the six months ended April 30, 1999, were $46.8
million, compared with $34.8 million for the same period in 1998. Utility
construction expenditures for the twelve-month period ended April 30, 1999, were
$105.6 million, compared with $83.4 million for the same period in 1998.

At April 30, 1999, our capitalization consisted of 42% in long-term debt and 58%
in common equity.

Results of Operations

We will discuss the results of operations for the three months, six months and
twelve months ended April 30, 1999, compared with the same periods in 1998.

Margin

Margin (operating revenues less cost of gas) for the three months ended April
30, 1999, decreased $207,000 compared with the same period in 1998 primarily for
the reasons listed below.

         -        Margin was reduced in South Carolina, effective November 1,
                  1998, as ordered by the Public Service Commission of South
                  Carolina (PSCSC), to eliminate the recovery of demand side
                  management (DSM) costs included in rates.
         -        Adjustments required by regulatory authorities resulted in
                  margin decreases from the same period in 1998.

Decreases in margin for the three-month period were partially offset by the
following increases.

         -        Weather was 3% colder than the same period in 1998.
         -        Delivered volumes of natural gas, which we refer to as system
                  throughput, increased over the same period in 1998 by 151,000
                  dekatherms.
         -        Volumes from secondary market sales increased over the same
                  period in 1998 by 749,000 dekatherms, a 6% increase. Secondary
                  market sales include sales for resale, off-system sales,
                  capacity release and other interstate transactions.

         -        Weather was 5% warmer than normal. The warmer-than-normal
                  weather generated operating revenues of $8.9 million from the
                  weather normalization adjustment (WNA). The WNA is designed to
                  offset the impact of unusually cold or warm weather, compared
                  with normal, on customer billings and operating margin. The
                  same period in 1998 reflected increased operating revenues of
                  $5.8 million from the WNA.

Margin for the six months ended April 30, 1999, decreased $1.7 million compared
with the same period in 1998 primarily for the reasons listed below.

         -        Delivered volumes of natural gas decreased from the same
                  period in 1998 by 6.3 million dekatherms, a 7% decrease.
         -        We changed rates in South Carolina to eliminate the recovery
                  of DSM costs as noted above.

Decreases in margin for the six-month period were partially offset by the
following increases.

         -        Volumes from secondary market sales increased over the same
                  period in 1998 by 4.8 million dekatherms, a 22% increase.
         -        Weather was 10% warmer than the same period in 1998, and 14%
                  warmer than normal. The warmer-than-normal weather generated
                  operating revenues of $19.7 million from the WNA. The same
                  period in 1998 reflected increased operating revenues of $5
                  million from the WNA.

Margin for the twelve months ended April 30, 1999, decreased $3.3 million
compared with the same period in 1998 primarily for the reasons listed below.

         -        Delivered volumes of natural gas decreased from the same
                  period in 1998 by 3.9 million dekatherms, a 3% decrease.
         -        We changed rates in South Carolina to eliminate the recovery
                  of DSM costs as noted above.

Decreases in margin for the twelve-month period were partially offset by the
following increases.

         -        Volumes from secondary market sales increased over the same
                  period in 1998 by 6.5 million dekatherms, a 21% increase.
         -        Weather was 16% warmer than normal and 14% warmer than the
                  same period in 1998 and generated $19.7 million in operating
                  revenues from the WNA. The same period in 1998 reflected
                  increased operating revenues of $5 million from the WNA from
                  3% warmer-than-normal weather.

Our rate schedules include provisions permitting the recovery of prudently
incurred gas costs. Regulatory commissions in North Carolina and South Carolina
require annual prudence reviews covering a historical twelve-month period;
however, such review is not required in Tennessee.

                                       -8-
<PAGE>   9


We revise rates in all three states 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 are added to or deducted from cost of gas and
included in refunds due customers in the financial statements.

Operations and Maintenance Expenses

Operations and maintenance expenses for the three months ended April 30, 1999,
compared with the same period in 1998 increased by $414,000 primarily for the
reasons listed below.

          -       Increase in outside labor,
          -       Increase in consultants fees and
          -       Increase in office supplies expenses.

Decreases in payroll, advertising expenses and employee benefits partially
offset these increases for the three months ended April 30, 1999, compared with
the same period in 1998.

Operations and maintenance expenses for the six months ended April 30, 1999,
compared with the same period in 1998 decreased by $224,000 primarily for the
reasons listed below.

         -        Decrease in provision for uncollectibles,
         -        Decrease in advertising expenses and
         -        Decrease in employee benefits.

An increase in outside labor partially offset these decreases for the six months
ended April 30, 1999, compared with the same period in 1998.

Operations and maintenance expenses for the twelve months ended April 30, 1999,
compared with the same period in 1998 decreased by $4 million primarily for the
reasons listed below.

         -        Decrease in payroll,
         -        Decrease in transportation expenses,
         -        Decrease in provision for uncollectibles,
         -        Decrease in risk insurance expenses and
         -        Decrease in advertising expenses.

Increases in outside labor expenses and materials and office supplies expenses
partially offset these decreases for the twelve months ended April 30, 1999,
compared with the same period in 1998.

General Taxes

General taxes for the three months ended April 30, 1999, compared with the same
period in 1998 decreased slightly by $66,000 primarily for the reasons listed
below.

                                       -9-
<PAGE>   10


         -        Decrease in gross receipts taxes from lower sales to customers
                  of volumes on which gross receipts taxes are charged and
         -        Decrease in payroll taxes.

An increase in franchise tax payments partially offset these decreases for the
three months ended April 30, 1999, compared with the same period in 1998.

General taxes for the six months ended April 30, 1999, compared with the same
period in 1998 decreased by $2.1 million primarily for the reasons listed below.

         -        Decrease in gross receipts taxes from lower sales to customers
                  and
         -        Decrease in payroll taxes.

General taxes for the twelve months ended April 30, 1999, compared with the same
period in 1998 decreased by $2 million primarily for the reasons listed below.

         -        Decrease in gross receipts taxes from lower sales to customers
                  and
         -        Decrease in payroll taxes.

Increases in property taxes and franchise taxes partially offset these decreases
for the twelve months ended April 30, 1999, compared with the same period in
1998.

Other Income

Other income for the three months ended April 30, 1999, compared with the same
period in 1998 decreased by $502,000. The primary reasons for these decreases
are listed below.

         -        Decrease in earnings from jobbing operations,
         -        Decrease in earnings from energy marketing services and
         -        Decrease in interest income.

These decreases in other income were partially offset by the following
increases.

         -        Increase in earnings from propane operations,
         -        Increase in earnings from merchandise operations and
         -        Increase in the allowance for funds used during construction.

Other income for the six months ended April 30, 1999, compared with the same
period in 1998 decreased by $1.7 million. Other income for the twelve months
ended April 30, 1999, compared with the same period in 1998 decreased by $3.2
million. The primary reasons for these decreases are listed below.

         -        Decrease in earnings from propane operations due to warmer
                  weather,
         -        Decrease in earnings from energy marketing services,


                                      -10-
<PAGE>   11


         -        Decrease in earnings from jobbing operations and
         -        Decrease in interest income.

Increases in earnings from merchandise operations and in the allowance for funds
used during construction partially offset these decreases in other income for
the six-month and twelve-month periods ended April 30, 1999, compared with the
same periods in 1998.

Utility Interest Charges

Utility interest charges for the three months ended April 30, 1999, compared
with the same period in 1998 decreased by $431,000. Utility interest charges for
the six months ended April 30, 1999, compared with the same period in 1998
decreased by $416,000. The primary reasons for these decreases are listed below.

         -        Decrease in interest in long-term debt from lower amounts of
                  debt outstanding and
         -        Decrease in interest incurred on refunds due customers.

An increase in interest on short-term debt due to higher amounts outstanding but
at slightly lower interest rates partially offset these increases in utility
interest charges for the three-month and six-month periods ended April 30, 1999,
compared with the same periods in 1998.

Utility interest charges for the twelve months ended April 30, 1999, compared
with the same period in 1998 decreased by $797,000 primarily due to a decrease
in interest in long-term debt from lower amounts of debt outstanding. Increases
in interest on refunds due customers due to higher amounts outstanding and in
interest on short-term debt at higher amounts outstanding but at slightly lower
interest rates partially offset this decrease.


Year 2000

Overview

In 1996, we formed a Year 2000 Project Team and selected a consulting firm to
help us. Since that time, we have undertaken a comprehensive company-wide
project to inventory, assess, remediate and test hardware, software and embedded
systems intended to make them Year 2000 ready. In December 1997, we formed a
Year 2000 Sub-Committee composed of senior-level executives to monitor Year 2000
efforts and assure that our core systems would be Year 2000 ready prior to the
turn of the century.

In support of Year 2000 efforts, we also formed a Test Management Group that has
established specific testing processes and procedures that are being used with
both Information Technology (IT) and non-IT systems. The testing methodology
includes the use of various testing techniques



                                      -11-
<PAGE>   12


such as regression, system, parallel, interface and stress testing. Test plans
include additional testing scenarios to demonstrate Year 2000 readiness. The
Test Management Group reviews the results of these tests to ensure that a
particular system's functional and Year 2000 readiness testing matches the
testing methodology.

Although extensive testing is being completed prior to the system
implementations, we will perform additional testing during 1999. During the
third calendar quarter of 1999, we intend to conduct a final Year 2000
company-wide review to verify that all issues have been adequately addressed.

Readiness of Systems, Applications and Embedded Devices

We have completed an inventory and assessment of the entire portfolio of
hardware, software and embedded systems. The compliance or non-compliance of
systems was based on written responses or Internet web site information from
vendors. Based on those findings, we developed a Year 2000 Master Plan that
outlined a remediation strategy to either repair, replace, upgrade or retire
each system, application or device that was deemed non-compliant. In an effort
to prioritize the Year 2000 efforts, we classified each system, application or
device as either mission critical, support intensive or low impact based on
certain factors that describe its relative importance to the business. The Year
2000 Sub-Committee reviewed and approved these classifications and strategies.

The four criteria used to classify a system, application or device as mission
critical are as follows, listed in order of importance:

         -        provide for public or employee safety,
         -        provide for gas supply or service to customers,
         -        provide the ability to comply with regulatory or legal
                  requirements and
         -        provide a sustained level of business and income.

Support-intensive systems are described as "systems providing a major part of
the business operation but an alternative solution could be formulated and
executed." Low-impact applications are defined as "systems that assist with
operations but whose failure would cause only minor inconvenience."

We completed the implementation of Year 2000 ready solutions for our
mission-critical applications by December 31, 1998. Examples of these
applications are SCADA (real-time system pressure and flow monitoring), Customer
Information, Telemetering, Materials Management, Gas Management, Accounts
Payable, General Ledger and Asset Management. Many of our support-intensive and
low-impact applications were also Year 2000 ready by the end of December 1998.
We expect all remaining applications to be complete by September 30, 1999.



                                      -12-

<PAGE>   13

We completed the inventory and assessment of embedded systems and found that
approximately 4% of the devices have a Year 2000 impact. We developed a
remediation strategy for each of the impacted devices and have completed the
upgrades on 93% of the impacted systems. In a few cases, the current
availability of hardware or software components or scheduling conflicts with
vendors have affected our ability to implement a Year 2000 ready solution by our
target date of April 30, 1999. The upgrades to these remaining devices should be
completed by June 30, 1999.

Suppliers and Vendors

During our efforts, it became clearly evident that we are dependent on a variety
of vendors and suppliers to provide essential equipment, materials and services.
In many ways, our ability to continue normal business operations is dependent on
the timely delivery of these goods and services. We have committed significant
resources to contacting our critical suppliers and assessing their readiness. In
cases where suppliers are non-responsive or demonstrate a significant risk of
being non-compliant, we are identifying alternative sources. In other cases, we
are planning to increase our inventory levels of specific critical items. We
anticipate this work effort will be complete by June 30, 1999. Our intent is to
avoid or minimize the impact of any disruptions associated with the inability of
a given supplier to respond to our business needs.

Risks

The Year 2000 Sub-Committee reviewed and approved ten specific "worst case"
scenarios. We designated plan owners for each scenario and they are developing
contingency plans to address each of the items. We anticipate the development of
these plans will be complete by June 30, 1999. Worst case scenarios are as
follows:

         -        electrical outages
         -        telecommunication outages
         -        natural gas shortages
         -        water outages
         -        vehicle fuel shortages
         -        staff shortages
         -        postal service outages
         -        data center services outages
         -        emergency response impacts and
         -        financial institution impacts.

We currently have in place the following that can be used to mitigate risks,
minimize potential impacts and provide safe uninterrupted service to customers:

         -        a territory-wide radio system to overcome telecommunication
                  outages,
         -        natural gas-powered backup electrical generators at regional
                  operations centers,

                                      -13-
<PAGE>   14

         -        liquefied natural gas facilities that can provide short-term
                  gas supply,
         -        a hot-site disaster recovery provider for computer services
                  and
         -        warehouse facilities that allow stockpiling of critical
                  supplies.

Contingency Planning

We are currently developing contingency plans in the areas of facilities,
applications, suppliers, embedded technologies and worst case scenarios. We are
following a standard template that was developed based on guidelines outlined by
the General Accounting Office for Year 2000 Business Continuity and Contingency
Planning. The contingency planning process assumes that there will be multiple
concurrent failures of systems, thus requiring an additional level of planning
to compensate for any assumptions that are made within a particular contingency
plan. We anticipate the development of contingency plans will be complete by
June 30, 1999. During the third calendar quarter of 1999, we intend to test
selected contingency plans based on potential risks.

In an effort to reduce our risk from staff shortages, we established a new
policy regarding the vacation schedules of personnel before and after January 1,
2000. The policy states that employee vacations will be suspended during the
last two weeks of December 1999 and the month of January 2000. The policy
provides for certain exceptions and reserves the right for management to
determine final work or vacation schedules based on the needs of our business
and customers.

Although we have not yet completed the contingency planning process, it is
reasonable to assume that any combination of worst case scenarios, coupled with
application or system failures, would result in a material adverse effect on
financial position or results of operations.


Financial Impact

We estimate our total costs for Year 2000 readiness, including inventory,
assessment, replacements, upgrades, repairs and testing, to be between $23
million and $25 million, of which $20.8 million has been incurred as of April
30, 1999. Total operating costs are estimated to be between $4 million and $5
million. By order of the North Carolina Utilities Commission, we defer and
amortize over a three-year period the portion of the operating costs
attributable to North Carolina (57% based on utility plant in service). Of the
total estimated costs, we will capitalize costs of $19 million to $20 million to
replace certain existing applications with new systems that will be Year 2000
operational and provide additional business management information and
functionality. Until we have completed further analysis of Year 2000 impacts on
our supplier and vendor relationships and contingency planning, an estimate of
any additional costs to be incurred as a result of these efforts cannot be
determined. We have not had to defer or cancel any planned IT projects due to
Year 2000 issues.




                                      -14-
<PAGE>   15


At April 30, 1999, we have expensed $2.5 million, deferred $1.5 million and
capitalized $16.8 million. We expect that these Year 2000 costs will be funded
by revenues generated from operations or through borrowings under existing
credit agreements. The projected Year 2000 costs for fiscal 1999 comprise
approximately 33% of the IT budget.

We expect that all necessary systems will be Year 2000 ready by late September
1999. As progress is made, we continually revise the master plan to address the
risks of Year 2000 issues, including contingency plans as appropriate to address
worst case scenarios. We do not expect the total capital and operating costs
associated with Year 2000 readiness, including assessment, replacement and
remediation, to significantly impact financial position or results of
operations.

                           PART II. OTHER INFORMATION

Item 5.   Other Information

Expansion Funds

As previously reported, the North Carolina Utilities Commission (NCUC) ordered
the establishment of an expansion fund for us and approved initial funding with
supplier refunds due customers to enable the expansion of natural gas service
into unserved areas of the state. At April 30, 1999, the North Carolina State
Treasurer held $28.1 million in our expansion fund account. This amount along
with other supplier refunds, including interest earned to date, is included in
restricted cash in the consolidated balance sheet. The NCUC decides the use of
these funds as we file individual project applications for unserved areas.

In June 1998, we filed a petition with the NCUC for approval of an expansion
project that would extend natural gas service to the counties of Avery, Mitchell
and Yancey. In that petition, we also requested authority to use $26.3 million
in expansion fund money to pay a portion of the estimated cost of the project of
$31.9 million. In November 1998, the NCUC issued an order approving our
requests.

On January 26, 1999, we filed an affidavit with the NCUC proposing an alternate
route of the pipeline to these counties at the direction of the National Forest
Service at an additional cost of $1.5 million. On May 20, the NCUC approved the
transfer of an additional $1.5 million in supplier refunds to our expansion fund
held by the state. This provides funding of $27.8 million for the project, now
estimated to cost $33.4 million.

Tennessee Incentive Plan

As previously reported, the Tennessee Regulatory Authority (TRA) approved a
two-year experimental performance incentive plan effective July 1, 1996. The
plan eliminated annual prudence reviews and established an incentive-sharing
mechanism based on differences in the actual cost of gas purchased and benchmark
rates, together with income from marketing transportation and storage capacity
in the secondary market, subject to an overall annual cap of $1.6 million on
gains or losses by us. The benefits of the incentive plan are the elimination of
annual gas purchase prudence reviews, reduction of gas costs for ratepayers and
potential earnings to shareholders by sharing in gas cost reductions. On August
18, 1998, the TRA orally approved our application to automatically renew the
performance incentive plan each year. On March 11, 1999, the TRA issued its
written order authorizing the continuance of the incentive plan each July 1
until we notify the TRA of termination 90 days before the end of a plan year or
until the plan is modified, amended or terminated by the TRA. An independent
review of the incentive plan is eliminated by the order.

Pine Needle LNG Company, L.L.C. (Pine Needle)

On May 1, 1999, the liquified natural gas (LNG) peak-demand facility located in
North Carolina began operations. We own 35% of the project through a subsidiary,
Piedmont Interstate Pipeline Company. Storage capacity is four billion cubic
feet with vaporization capability of 400 million cubic feet per day.


                                      -16-
<PAGE>   17


We have subscribed to one-half of this capacity to provide gas for peak-use
periods in winter when demand is the highest. As previously reported, Pine
Needle financed the construction of the facility through construction loans,
with permanent financing at the end of the construction period. On May 3, we
made an equity contribution of $18.7 million to Pine Needle to cover our portion
of the permanent financing.

Corporate Organization

On June 4, 1999, the Board of Directors elected Ware F. Schiefer, President and
Chief Operating Officer, to the Company's Board of Directors.
