                                     PART I

Item 1.  Business

         Piedmont Natural Gas Company, Inc., incorporated in 1950, is an energy
and services company primarily engaged in the distribution and sale of natural
gas and the sale of propane to over 710,000 residential, commercial and
industrial customers in North Carolina, South Carolina and Tennessee.

         We are the second-largest natural gas utility in the Southeast, serving
over 660,000 customers. Along with our non-utility subsidiaries and divisions,
we are also engaged in acquiring, marketing, transporting and storing natural
gas for large-volume customers, in retailing residential and commercial gas
appliances and in the sale of propane to over 48,000 customers in our
three-state service area.

         In the Carolinas, our service area is comprised of numerous cities,
towns and communities including Anderson, Greenville and Spartanburg in South
Carolina and Charlotte, Salisbury, Greensboro, Winston-Salem, High Point,
Burlington and Hickory in North Carolina. In Tennessee, our service area is the
metropolitan area of Nashville. Our propane market is in and adjacent to our
natural gas market in all three states.

         We have one reportable business segment, domestic natural gas
distribution. This business is conducted by the parent company and two wholly
owned subsidiaries, Piedmont Intrastate Pipeline Company and Piedmont Interstate
Pipeline Company. Piedmont Intrastate is a member of Cardinal Pipeline Company,
L.L.C., which owns and operates a natural gas pipeline. Piedmont Interstate is a
member of Pine Needle LNG Company, L.L.C., which owns a liquified natural gas
storage facility.

         All of our other activities are conducted by wholly owned subsidiaries,
Piedmont Propane Company and Piedmont Energy Company. Piedmont Propane markets
propane and propane appliances to residential, commercial and industrial
customers. Piedmont Energy has an equity interest in SouthStar Energy Services
LLC which offers a combination of unregulated energy products and services to
over 476,000 industrial, commercial and residential customers in the
southeastern United States.

         Operating revenues shown in the consolidated financial statements
represent revenues from utility operations only. Such revenues totaled
$686,470,000 for the year ended October 31, 1999, of which 43% was from
residential customers, 24% from commercial customers, 21% from industrial
customers, 11% from secondary market activity and 1% from various sources.
Revenues from non-utility operations, less related costs and income taxes, are
shown in the consolidated financial statements in other income. For further
segment

information, see "Note 8. Business Segments and Other Non-Utility Activities" in
Item 8 of this report on page 41.

         Our utility operations are subject to regulation by the North Carolina
Utilities Commission (NCUC), the Public Service Commission of South Carolina
(PSCSC) and the Tennessee Regulatory Authority (TRA) as to rates, service area,
adequacy of service, safety standards, extensions and abandonment of facilities,
accounting and depreciation. We are also subject to regulation by the NCUC as to
the issuance of securities. We are also subject to or affected by various
federal regulations.

         We hold non-exclusive franchises for natural gas service in all
communities where required, with expiration dates from 2000 to 2048. February
2000 is the earliest date at which a franchise for a major service area expires
and renewal is currently being arranged. The franchises are adequate for
operation of the gas distribution business and do not contain restrictions which
are of a materially burdensome nature. In most cases, the loss of a franchise
would not have a material effect on operations. We have never failed to obtain
the renewal of a franchise; however, this is not necessarily indicative of
future action.

         Our utility business and non-utility propane activities are seasonal in
nature as variations in weather conditions generally result in greater earnings
during the winter months. We normally inject natural gas into storage during
summer months (principally April 1 through October 31) for withdrawal from
storage during winter months (principally November 1 through March 31) when
customer demand is higher. During 1999, the amount of natural gas in storage
varied from 9.8 million dekatherms (one dekatherm equals 1,000,000 BTUs) to 21.1
million dekatherms, and the aggregate commodity cost of this gas in storage
varied from $19,985,000 to $47,583,000.

         The following is a five-year comparison of gas sales and other
statistics for the years ended October 31, 1995 through 1999:

         During 1999, we delivered 136 million dekatherms of natural gas to our
customers, of which 44.6 million dekatherms were transported for large
industrial customers. This compares with 143 million dekatherms delivered in
1998, of which 42 million



                                       3

dekatherms were transported. In addition to this system throughput,
secondary-market sales volumes increased to 34.8 million dekatherms in 1999,
compared with 34 million dekatherms in 1998.

         Sales to temperature-sensitive customers, whose consumption varies with
the weather, were 64.8 million dekatherms in 1999, compared with 69.7 million
dekatherms in 1998. Weather which was 13% warmer than normal was experienced in
1999, compared with 8% warmer-than-normal weather in 1998. We sold or
transported 7 million dekatherms to power generation customers in 1999, compared
with 9.1 million dekatherms in 1998. We sold or transported 64.2 million
dekatherms to industrial users in 1999 and 1998. Industrial sales are the most
price-sensitive of our markets and are largely a function of our ability to
obtain supplies of natural gas competitively priced with other industrial fuels.

         Except as set forth below, all natural gas distributed is transported
to us by one or more of eight interstate pipelines, Transcontinental Gas Pipe
Line Corporation (Transco), Tennessee Gas Pipeline Company, Texas Eastern
Transmission Corporation, Columbia Gas Transmission Company, Columbia Gulf
Transmission Corporation, National Fuel Gas Supply Corporation, Texas Gas
Transmission Corporation and CNG Transmission Corporation.

         As of November 1, 1999, we have contracted to purchase the following
pipeline long-term firm transportation capacity in dekatherms of daily
deliverability:

</TABLE>

         We utilize a "best cost" gas purchasing philosophy that seeks to
purchase gas on a short- or long-term basis by weighing cost against supply
security and reliability factors. In 1999,



                                       4
<PAGE>   7

130.6 million dekatherms of natural gas were purchased.

         We own or have under contract 24.7 million dekatherms of storage
capacity, either in the form of underground storage or LNG. This capability is
used to supplement regular pipeline supplies on colder winter days when demand
increases.

         For further information on gas supply and regulation, see "Gas Supply
and Regulatory Proceedings" included in Management's Discussion and Analysis of
Financial Condition and Results of Operations in Item 7 of this report.

         Approximately 32% of annual gas deliveries in 1999 were made to
industrial or large commercial customers who have the capability to burn a fuel
other than natural gas. The alternative fuels are primarily fuel oil and some
propane and, to a much lesser extent, coal or wood. The ability to maintain or
increase deliveries of gas to these customers depends on a number of factors,
including weather conditions, governmental regulations, the price of gas from
suppliers and the price of alternate fuels. Under existing regulations of the
Federal Energy Regulatory Commission (FERC), certain large commercial or
industrial customers located in proximity to the interstate pipelines delivering
gas to us could attempt to bypass us and take delivery of gas directly from the
pipeline or from a third party connecting with the pipeline. To date, only
minimal bypass activity has been experienced in part because of our ability to
negotiate competitive rates and service terms. The future level of bypass
activity cannot be predicted.

         In the residential and small commercial markets, natural gas competes
primarily with electricity for such uses as cooking and water heating and with
electricity and fuel oil for space heating.

         During 1999, our largest customer contributed $19,745,000, or 3%, to
total operating revenues.

         We spend an immaterial amount for research and development costs. We
contribute to gas industry-sponsored research projects; however, the amounts
contributed to such projects are minimal.

         Compliance with federal, state and local environmental protection laws
had no material effect on capital expenditures, earnings or competitive position
during 1999. For further information on environmental issues, see "Environmental
Matters" included in Management's Discussion and Analysis of Financial Condition
and Results of Operations in Item 7 of this report.

         As of October 31, 1999, we had 1,821 employees, compared with 1,841
employees as of October 31, 1998.

Item 2.  Properties

         Our properties consist primarily of distribution systems and related
facilities to serve our utility customers. We have constructed and own
approximately 526 miles of lateral pipelines up to 16 inches in diameter which
connect our distribution systems with the transmission systems of our pipeline
suppliers. Natural gas is distributed through approximately 18,400 miles
(three-inch equivalent) of distribution mains. The lateral pipelines and
distribution mains are located on or under public streets and highways, or
private property with the permission of the individual owners.

         We either own or lease for varying periods district and regional
offices for our utility and non-utility operations.


Item 3.  Legal Proceedings

         There are a number of lawsuits pending against us in the ordinary
course of business for damages alleged to have been caused by our employees. We
have liability insurance which we believe is adequate to cover any material
judgments which may result from these lawsuits.


Item 4.  Submission of Matters to a Vote of Security Holders

         None.

Item 7. Management's Discussion and Analysis of Financial Condition and Results
of Operations

Liquidity and Capital Resources

         The gas distribution business is highly weather sensitive and seasonal.
This weather sensitivity and seasonality cause short-term cash requirements to
vary significantly during the year. 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.
Short-term debt may be used to finance construction pending the issuance of
long-term debt or equity. We sell common stock and long-term debt to cover cash
requirements when market or other conditions are favorable for such long-term
financing.

         Various banks provide lines of credit totaling $75 million for these
direct short-term borrowings. Additional lines are also available on an as
needed, if available, basis. These short-term borrowings include bankers'
acceptances, transactional borrowings and overnight cost-plus loans based on the
lending bank's cost of money, with a maximum rate of the lending bank's
commercial prime interest rate. Outstanding short-term borrowings during 1999
ranged from zero to a high of $115 million and interest rates ranged from 4.88%
to 6.25% during the year. At October 31, 1999, $79.5 million of short-term debt
was outstanding at a weighted average interest rate of 5.63%.


                                       8
<PAGE>   11

         We had $425 million of long-term debt outstanding at October 31, 1999.
Annual sinking fund requirements and maturities of this debt are $2 million in
2000, $32 million in 2001, $2 million in 2002, $47 million in 2003 and $2
million in 2004. Long-term debt retired in 1999 totaled $46 million.

         On September 15, 1999, we prepaid our 10.02% and 10.11% Senior Notes
due in 2003 and 2004, respectively, in the amount of $36 million plus accrued
interest and an early payment premium of $1.1 million. To fund this prepayment
and for other working capital and construction purposes, we issued two
medium-term notes under a shelf registration statement for $150 million of debt
securities that was filed with the Securities and Exchange Commission in 1997.
These two issues consist of $30 million of 7.35% notes due 2009 and $60 million
of 7.95% notes due 2029. Both notes are to be redeemed in a single payment at
maturity.

         At October 31, 1999, our capitalization ratio consisted of 46%
long-term debt and 54% common equity. The embedded cost of long-term debt at
that date was 8.04%. The return on average common equity in 1999 was 12.25%.

         Cash provided from operations, from financing and from the issuance of
Common Stock through dividend reinvestment and stock purchase plans was
sufficient to fund capital expenditures of $103.6 million, payments of debt
principal and interest of $78.7 million and dividend payments to shareholders of
$42.2 million.

         We have a substantial capital expansion program for construction of
distribution facilities, purchase of equipment and other general improvements
funded through sources noted above. The capital expansion program supports our
5% current annual growth in customer base. Utility capital expenditures for 1999
were $102 million. Non-utility capital expenditures in 1999 were $1.6 million.
In addition, we made an equity contribution in 1999 of $18.7 million to cover
our portion of the permanent financing of a liquified natural gas peak-demand
facility in which we have an equity interest. Utility capital expenditures
totaling $116.7 million, primarily to serve customer growth, and $2.6 million
for non-utility activities are budgeted for 2000.

Competition and Accounting for Regulated Activities

         The natural gas industry, including producers, pipelines and local gas
distribution companies (LDCs), has undergone significant changes in recent years
in moving toward a less-regulated marketplace. In response to the changing
competitive situation, we continue to assess the nature of our business and


                                       9
<PAGE>   12

explore alternatives to the traditional utility role of purchase, sale and
transportation of natural gas. Non-traditional ratemaking initiatives and
market-based pricing of products and services provide additional challenges and
opportunities for us. We anticipate that opportunities for non-regulated sales
will increase as competition intensifies and further retail market unbundling
occurs.

         We account for our regulated activities in accordance with Statement of
Financial Accounting Standards (SFAS) No. 71, "Accounting for the Effects of
Certain Types of Regulation" (FAS 71). FAS 71 provides that rate-regulated
public utilities account for and report assets and liabilities consistent with
the economic effect of the manner in which independent third-party regulators
establish rates. In applying FAS 71, we have capitalized certain costs and
benefits as regulatory assets and liabilities, respectively, pursuant to orders
of state utility regulatory commissions, either in general rate proceedings or
expense deferral proceedings, in order to provide for recovery of or refunds to
utility customers in future periods. As competition increases and we are further
subjected to the impact of deregulation, we may not be able to continue to apply
FAS 71 to all or parts of our business. If this were to occur, we would be
required to apply accounting standards utilized by non-regulated enterprises. At
such time as we determine that the provisions of FAS 71 no longer apply, costs
previously deferred as regulatory assets in the consolidated balance sheet would
be eliminated, net of the elimination of any regulatory liabilities. The
composition and amount of regulatory assets and liabilities are shown in Note 1
to the consolidated financial statements.

         While we believe the provisions of FAS 71 continue to apply to our
regulated operations, the changing nature of the business requires continual
assessment of the impact of those changes on our accounting policies.

Gas Supply and Regulatory Proceedings

         To meet customer requirements, we must acquire sufficient gas supplies
and pipeline capacity to ensure delivery to our distribution system while also
ensuring that our supply and capacity contracts will allow us to remain
competitive. We have a diversified portfolio of local peaking facilities,
transportation and storage contracts with interstate pipelines and supply
contracts with major producers and marketers to satisfy the supply and
deliverability requirements of our customers.

         In our opinion, present rules and regulations of our three


                                       10
<PAGE>   13

state utility regulators, the North Carolina Utilities Commission (NCUC), the
Public Service Commission of South Carolina (PSCSC) and the Tennessee Regulatory
Authority (TRA), permit the pass through of interstate pipeline capacity and
storage service costs, as well as gas commodity costs from natural gas
suppliers, that may be incurred under orders or regulations of the Federal
Energy Regulatory Commission (FERC). The majority of our natural gas supply is
purchased from producers and marketers in non-regulated transactions. Our rate
schedules include provisions permitting the recovery of prudently incurred gas
costs. The NCUC and the PSCSC require annual prudence reviews covering a
historical twelve-month period; however, such review is not required in
Tennessee. For the most recent twelve-month period, the NCUC and the PSCSC found
us to be prudent in our gas purchasing practices and allowed 100% recovery of
our gas costs.

         In 1996, the TRA approved a two-year experimental performance incentive
plan effective July 1, 1996, which 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. The plan is 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. In 1998, the TRA renewed the
plan and in 1999 authorized the continuance of the 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.

         Secondary market transactions permit us to market short-term gas
supplies and transportation services by contract with wholesale or off-system
customers. These sales contribute the smallest per-unit margin to earnings;
however, the program allows us to act as a wholesale marketer of natural gas and
transportation capacity in order to generate operating margin from sources not
restricted by the capacity of our retail distribution system. In North Carolina,
a sharing mechanism is in effect where 75% of any margin earned is refunded to
firm customers. Sales in Tennessee are included in the rate-sharing mechanism
under the performance incentive plan.

         Approximately 32% of annual gas deliveries in 1999 were made to
industrial or large commercial customers who have the capability to burn a fuel
other than natural gas. The alternative fuels are primarily fuel oil and some
propane and, to a much lesser extent, coal or wood. The ability to maintain or


                                       11
<PAGE>   14

increase deliveries of gas to these customers depends on a number of factors,
including weather conditions, governmental regulations, the price of gas from
suppliers and the price of alternate fuels. Under existing regulations of the
FERC, certain large commercial or industrial customers located in proximity to
the interstate pipelines delivering gas to us could attempt to bypass us and
take delivery of gas directly from the pipeline or from a third party connecting
with the pipeline. To date, only minimal bypass activity has been experienced in
part because of our ability to negotiate competitive rates and service terms.
The future level of bypass activity cannot be predicted.

         The NCUC has established an expansion fund consisting of supplier
refunds due customers to be used to extend natural gas service into unserved
areas of the state. As of October 31, 1999, the North Carolina State Treasurer
held $30.5 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 November 1998, the NCUC issued an order approving our request for an
expansion project to extend natural gas service to the counties of Avery,
Mitchell and Yancey. We 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 January 1999, we proposed an alternate route to these counties and
in May the NCUC approved the transfer of an additional $1.5 million in supplier
refunds to our expansion fund. This provides funding of $27.8 million for the
project, now estimated to cost $33.4 million.

         In December 1999, we filed with the TRA for a general rate increase of
$10.7 million annually. The case is expected to be set for hearing in early
2000.

Results of Operations

         Net income for 1999 was $58.2 million, compared with $60.3 million in
1998 and $54.1 million in 1997.

         Net income for 1999 decreased $2.1 million from 1998 primarily for the
reasons listed below.

         -        Sales decreased in all customer classes.
         -        Earnings decreased from propane operations.
         -        Earnings decreased from unregulated retail energy marketing
                  services.


                                       12
<PAGE>   15

         -        Depreciation expense increased.

         These decreases were partially offset for the reasons listed below.

         -        Operations expenses decreased.
         -        General taxes decreased.
         -        Utility interest charges decreased.

         Net income for 1998 increased $6.2 million from 1997 primarily for the
reasons listed below.

         -        Regulatory rate changes increased rates and updated gas cost
                  components.
         -        Secondary market transactions increased.
         -        Interest income increased.
         -        Operations and maintenance expenses decreased.
         -        General taxes decreased.
         -        Utility interest charges decreased.

         An increase in depreciation expense partially offset these increases in
net income.

         Compared with the prior year, weather in our service area was 6% warmer
in 1999, 4% warmer in 1998 and 13% warmer in 1997. Volumes of gas delivered to
customers, which we refer to as system throughput, were 136 million dekatherms
in 1999, compared with 143 million dekatherms in 1998, a decrease of 5%, and
135.1 million dekatherms in 1997. In addition to this system throughput,
secondary-market sales volumes increased to 34.8 million dekatherms in 1999,
compared with 34 million dekatherms in 1998 and 24.5 million dekatherms in 1997.

         Operating revenues were $686.5 million in 1999, $765.3 million in 1998
and $775.5 million in 1997.

         Operating revenues for 1999 decreased by $78.8 million from 1998
primarily for the reasons listed below.

         -        Sales to residential, commercial and industrial customers
                  decreased due to warmer weather.
         -        North Carolina gross receipts taxes were eliminated from rates
                  during 1999 (see discussion of General Taxes below).
         -        Revenues from secondary market activity decreased even though
                  volumes increased.

         Operating revenues for 1998 decreased by $10.2 million from 1997
primarily for the reasons listed below.



                                       13
<PAGE>   16

         -        A reduction in the embedded cost of gas which is a component
                  of revenue.
         -        The shift from sales of gas to transportation on which there
                  is no commodity cost included in revenues.
         -        Increased volumes in secondary market sales at wholesale
                  market rates which are lower than retail tariff rates.

         The weather normalization adjustment mechanism (WNA) generated revenues
of $19.7 million, $5 million and $10.6 million in 1999, 1998 and 1997,
respectively. The WNA in effect in all three states is designed to offset the
impact that unusually cold or warm weather has on residential and commercial
customer billings and margin. Weather 13% warmer than normal was experienced in
1999, compared with 8% warmer-than-normal weather in 1998 and 4%
warmer-than-normal weather in 1997.

         In general rate proceedings, the state regulatory commissions authorize
us to recover a margin, applicable rate less cost of gas, on each unit of gas
sold. Each commission has also authorized us to negotiate lower rates to certain
of our industrial customers when necessary to remain competitive. We are
generally permitted to recover margin losses resulting from these negotiated
transactions through rates. The ability to recover such negotiated margin
reductions is subject to continuing regulatory approvals.

         Cost of gas was $366 million in 1999, $442.4 million in 1998 and $460.7
million in 1997.

         Cost of gas for 1999 decreased $76.4 million from 1998 primarily for
the reasons listed below.

         -        Decreases in embedded gas costs.
         -        Increased volumes in secondary market sales at wholesale
                  market rates which are lower than retail tariff rates.
         -        Increases in capacity release transactions.

         Cost of gas for 1998 decreased $18.3 million from 1997 primarily for
the reasons listed below.

         -        Decreases in embedded gas costs.
         -        The shift from sales to transportation.
         -        Increased volumes in secondary market sales at wholesale
                  market rates which are lower than retail tariff rates.

         Increases or decreases in purchased gas costs from suppliers have no
significant impact on margin as substantially all changes are passed on to
customers through purchased gas adjustment procedures.



                                       14
<PAGE>   17

         Margin was $320.5 million in 1999, $322.9 million in 1998 and $314.9
million in 1997. Margin increased or decreased due to the changes in revenues
and cost of gas noted above. The margin earned per dekatherm of system
throughput increased by $.10 in 1999 over 1998 and decreased by $.07 in 1998
from 1997.

         Other operations and maintenance expenses were $116.8 million in 1999,
$119.6 million in 1998 and $126.8 million in 1997.

         Operations and maintenance expenses for 1999 decreased $2.8 million,
compared with 1998, primarily for the reasons listed below.

         -        Decrease in risk insurance expense.
         -        Decrease in office supplies expense.
         -        Decrease in payroll expense.
         -        Decrease in employee benefits expense.
         -        Decrease in the provision for uncollectibles.

         Increases in outside labor expense and advertising expense partially
offset these decreases in 1999.

         Operations and maintenance expenses for 1998 decreased $7.2 million,
compared with 1997, primarily due to the following reasons.

         -        Decrease in payroll expense.
         -        Decrease in rent expense.
         -        Decrease in advertising expense.
         -        Decrease in the provision for uncollectibles.

         An increase in outside labor expense partially offset these decreases
in 1998.

         As part of a plan to reduce overall operating expenses, the Company
eliminated 93 positions in 1997 which reduced the utility workforce by 5% from
the employee count as of the end of 1996. The workforce reduction plan resulted
in a charge to operations expense of $1.8 million in the fourth quarter of 1997.

         Depreciation expense increased from $39.2 million to $44.1 million over
the three-year period 1997 to 1999 primarily due to the growth in plant in
service.

         General taxes decreased from $32.9 million to $29.5 million over the
three-year period 1997 to 1999 primarily due to



                                       15
<PAGE>   18

decreases in gross receipts taxes charged on lower amounts billed to customers
and the elimination of North Carolina gross receipts taxes explained below.
Increases in property taxes resulting from rate increases and additions to
taxable property and state franchise taxes partially offset these decreases.

         Effective July 1, 1999, for bills rendered after August 1, 1999, we
began charging a new excise tax on piped natural gas used in North Carolina.
This tax replaced the sales and use tax and gross receipts tax that were
previously applicable to piped natural gas. The excise tax is calculated using a
declining block rate structure applied to the number of therms delivered each
month. The excise tax is not intended to increase or decrease taxes, but to
replace the combination of the sales and use tax and gross receipts tax.

         The gross receipts tax was included in our gas rates billed to
customers and therefore was in our operating revenues. Gross receipts tax
expense in the same amount was also included in general taxes. The sales and use
tax was not included in rates but was collected as a surcharge and remitted to
the state with no impact on the income statement. The excise tax follows the
previous sales and use tax treatment and is not included in revenues or
expenses. This change impacts the comparability of revenues and thus margin
(revenues less cost of gas) and general taxes for all periods prior to the
change.

         Other income, net of income taxes, decreased to a loss of $1.1 million
in 1999 compared with income of $2.3 million in 1998 and $4.1 million in 1997
primarily due to the following reasons.

         -        Decrease in earnings from unregulated retail energy marketing
                  services.
         -        Decrease in interest earned on temporary cash investments.

         Decreases in earnings from unregulated retail energy marketing services
result from start-up costs incurred by our retail marketing joint venture,
SouthStar Energy Services LLC (SouthStar), associated with its entry into the
unregulated retail gas market in Georgia.

         Increases in earnings from non-utility LNG operations and in the
allowance for funds used during construction partially offset these decreases.

         Utility interest charges were $32.4 million in 1999, $33.2 million in
1998 and $34 million in 1997.

         Utility interest charges for 1999 decreased $800,000, compared with
1998, primarily due to the following reasons.

         -        Decrease in interest on long-term debt due to lower balances
                  outstanding over the period.
         -        Decrease in interest charged on refunds due customers from
                  lower balances outstanding.
         -        Increase in the portion of the allowance for funds used during
                  construction attributable to borrowed funds.

         An increase in interest on short-term debt due to greater balances
outstanding even at slightly lower interest rates partially offset these
decreases in 1999.

         Utility interest charges for 1998 decreased $800,000, compared with
1997, primarily due to the following reasons.

         -        Decrease in interest on long-term debt due to lower balances
                  outstanding.
         -        Decrease in interest on short-term debt due to lower balances
                  outstanding but at slightly higher rates.
         -        Increase in the portion of the allowance for funds used during
                  construction attributable to borrowed funds.

         An increase in interest on refunds due customers due to higher balances
outstanding partially offset these decreases in 1998.

Environmental Matters

         We have owned, leased or operated manufactured gas plant (MGP)
facilities at 12 sites in our three-state service area. In 1997, we entered into
a settlement with a third party with respect to nine of these sites. As of
October 31, 1999, we had an environmental liability of $1.4 million for the
remaining three MGP sites not covered by the settlement. This liability is
estimated based on a generic MGP site study as we have not performed
site-specific evaluations.

         Our three state regulatory commissions authorized us to utilize
deferral accounting, or to create a regulatory asset, for expenditures made in
connection with environmental matters. In connection with the settlement noted
above and the estimated liability for the three remaining sites, we have
recorded a regulatory asset of $6.6 million. As of October 31, 1999, we had an
additional regulatory asset in the amount of $377,000, net of recoveries from
customers, for other environmental costs, primarily legal fees and engineering
assessments.



                                       17
<PAGE>   20

         Further evaluations of the three remaining sites could significantly
affect recorded amounts; however, we believe that the ultimate resolution of
these matters will not have a material adverse effect on financial position or
results of operations.

Accounting Pronouncements

         Effective November 1, 2000, we will adopt SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities" (FAS 133), as amended by SFAS No.
137, "Accounting for Derivative Instruments and Hedging Activities - Deferral of
the Effective Date of FASB Statement No. 133". We are currently evaluating the
effects of FAS 133 on financial position and results of operations.

Year 2000

Overview

         In 1996, we formed a Year 2000 Project Team and selected a consulting
firm to help us with a comprehensive company-wide project to inventory, assess,
replace, remediate and test hardware, software and embedded systems intended to
make them Year 2000 ready. In 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 these efforts, we also formed a Test Management Group who
established specific testing processes and procedures that were used with both
Information Technology (IT) and non-IT systems. The testing methodology included
the use of various testing techniques such as regression, system, parallel,
interface and stress testing. Test plans included additional testing scenarios
to demonstrate Year 2000 readiness. The Test Management Group reviewed the
results of these tests to verify that a particular system's functional and Year
2000 readiness testing was properly completed.

         During the fourth calendar quarter of 1999, we were required by some
software vendors to apply additional patches to systems that had been previously
upgraded or replaced. This work was completed and the systems were made Year
2000 ready.

         During the transition weekend of December 31, 1999, through January 3,
2000, we had personnel on-site to monitor our gas distribution network and to
verify that our computer systems did not experience any Year 2000 impacts. We
did not experience any failures that resulted in the loss of gas service to our
customers or that posed any safety-related issues to the public or our
employees.



                                       18

Readiness of Systems, Applications and Embedded Devices

         We completed the implementation of Year 2000 ready solutions for our
mission-critical applications in December 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. The final
application was completed on schedule in September 1999.

         We completed the inventory and assessment of embedded systems and found
that approximately 4% of the devices had a Year 2000 impact. We developed a
remediation strategy for each of the impacted devices and completed the upgrades
on all of those systems.

         We will continue to monitor the readiness status of our systems due to
the Year 2000 being a leap year in an effort to reduce the risk that any Year
2000 failures after January 1, 2000, could result in material impacts to us.

Suppliers and Vendors

         We are dependent on a variety of suppliers and vendors 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 committed significant resources to contacting our
critical suppliers and assessing their readiness. In cases where suppliers were
non-responsive or demonstrated a significant risk of being non-compliant, we
identified alternative sources. In other cases, we increased our inventory
levels of specific critical items. Our intent was to minimize or avoid 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 developed
contingency plans to address each of the items. Our worst case scenarios were as
follows:

         -        Electrical outages,
         -        Telecommunication outages,
         -        Natural gas shortages,
         -        Water outages,
         -        Vehicle fuel shortages,
         -        Staff shortages,
         -        Postal service outages,


                                       19
<PAGE>   22

         -        Data center services outages,
         -        Emergency response impacts, and
         -        Financial institution impacts.

         During the transition weekend, we were not required to invoke any
contingency plans related to our worst case scenarios.

Contingency Planning

         We developed contingency plans in the areas of facilities,
applications, suppliers, embedded technologies and worst case scenarios. We
followed a standard template based on guidelines outlined by the General
Accounting Office for Year 2000 Business Continuity and Contingency Planning.
The contingency planning process assumed that there could be multiple concurrent
failures of systems, thus requiring an additional level of planning to
compensate for any assumptions that were made within a particular contingency
plan. During September 1999, we completed the testing of selected contingency
plans based on potential risks.

         In addition, we developed a Year 2000 event plan that outlined the
staffing requirements and the system verification procedures that were utilized
during the transition weekend. The plan included a Command and Control Center
that was managed by one of our senior executives. Personnel in the center
monitored the system verification activities and coordinated the communication
of our status to state regulatory agencies, the American Gas Association and the
media.

         In an effort to reduce our risk from staff shortages, we established a
policy which limits employee vacations during December 1999 and 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.

Financial Impact

         We estimate our total costs for Year 2000 readiness, including
inventory, assessment, replacements, upgrades, repairs and testing, to be $23.6
million, substantially all of which was incurred as of October 31, 1999. Total
operating costs are estimated to be $4.3 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 capitalized costs of $19.3
million to replace existing applications with new systems that are Year 2000
operational and that provide additional business management information and
functionality. We did not defer or cancel any planned IT projects due to Year
2000 issues.



                                       20
<PAGE>   23

         As of October 31, 1999, we have expensed $3 million and deferred $1.3
million. Year 2000 costs were funded by revenues generated from operations or
through borrowings under existing credit agreements. The Year 2000 costs for
fiscal 1999 comprised approximately 33% of the IT budget.

         Total costs associated with Year 2000 readiness did not significantly
impact our financial position or results of operations.

     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

A. Operations and Principles of Consolidation.

         Piedmont Natural Gas Company, Inc., is an investor-owned public utility
primarily engaged in the sale and transportation of natural gas to residential,
commercial and industrial customers in the Piedmont region of North Carolina and
South Carolina and the metropolitan Nashville, Tennessee, area. The consolidated
financial statements include the accounts of our wholly owned subsidiaries. All
revenues and expenses of non-state-regulated operations are included in other
income in the consolidated income statements. Significant intercompany
transactions have been eliminated in consolidation where appropriate.

B. Utility Plant and Depreciation.

         Utility plant is stated at original cost, including direct labor and
materials, allocable overheads and an allowance for borrowed and equity funds
used during construction (AFUDC). AFUDC totaled $3,461,000 for 1999, $2,611,000
for 1998 and $1,418,000 for 1997. The portion of AFUDC attributable to equity
funds is included in other income, and the portion attributable to borrowed
funds is shown as a reduction of utility interest charges. The costs of property
retired are removed from utility plant and such costs, including removal costs
net of salvage, are charged to accumulated depreciation.

         We compute depreciation expense using the straight-line method. The
composite weighted-average rates were 3.38% for 1999, 3.43% for 1998 and 3.41%
for 1997.

         We review long-lived assets and certain identifiable intangibles for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Our review did not result in
a material effect on results of operations or financial condition.

C. Inventories.

         We maintain inventories on the basis of the average cost charged
thereto.

D. Deferred Purchased Gas Adjustment.

         Rate schedules include gas adjustment provisions that permit the
recovery of gas costs. 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.




                                       29
<PAGE>   32

E. Income Taxes.

         We provide deferred income taxes for differences between the book and
tax basis of assets and liabilities, principally attributable to accelerated tax
depreciation and the timing of the recording of revenues and cost of gas. We
amortize deferred investment tax credits to income over the estimated useful
life of the related property.

F. Operating Revenues.

         We recognize revenues from meters read on a monthly cycle basis which
results in unrecognized revenue from the cycle date through month end. We defer
the cost of gas for volumes delivered to customers but not yet billed under the
cycle-billing method.

G. Earnings Per Share.

         We compute basic earnings per share using the weighted average number
of shares of Common Stock outstanding during each period. A reconciliation of
basic and diluted earnings per share for the years ended October 31, 1999, 1998
and 1997, is presented below:

H. Rate-Regulated Basis of Accounting.

         Statement of Financial Accounting Standards (SFAS) No. 71, "Accounting
for the Effects of Certain Types of Regulation" (FAS 71), provides that
rate-regulated public utilities account for and report assets and liabilities
consistent with the economic effect of the manner in which independent
third-party regulators establish rates. In applying FAS 71, we have capitalized
certain costs and benefits as regulatory assets and liabilities, respectively,
pursuant to orders of the state utility regulatory commissions, either in
general rate proceedings or expense deferral proceedings, in order to provide
for recovery of or refunds to utility customers in future periods.


                                       30
<PAGE>   33

         We monitor the regulatory and competitive environment in which we
operate to determine that our regulatory assets continue to be probable of
recovery. If we, at some point in the future, determine that all or a portion of
these regulatory assets no longer meet the criteria for continued application of
FAS 71, then we would be required to write off that portion which we could not
recover, net of any regulatory liabilities which would be deemed no longer
necessary.

         The amounts recorded as regulatory assets and liabilities in the
consolidated balance sheets at October 31, 1999 and 1998, are summarized as
follows:

I. Statement of Cash Flows.

         For purposes of reporting cash flows, we consider all highly liquid
debt instruments purchased with an original maturity of three months or less to
be cash equivalents.

J.  Other Recently Issued Accounting Standards.

         SFAS No. 130, "Reporting Comprehensive Income", requires the reporting
and display of comprehensive income and its components in the financial
statements. We have no items of other comprehensive income in any period
presented.

         SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities" (FAS 133), requires all derivative instruments to be recognized on
the balance sheet at their fair value. Changes in the fair value of derivatives
are to be recorded each period either in other comprehensive income or in
current earnings depending on the use of the derivative and whether it qualifies
for hedge accounting. FAS 133, as amended by



                                       31
<PAGE>   34

SFAS No. 137, which deferred the effective date, is effective for all fiscal
quarters of fiscal years beginning after June 15, 2000. We are currently
evaluating the effects of FAS 133 on financial position and results of
operations.

K.  Use of Estimates.

         We make estimates and assumptions when preparing financial statements.
Those estimates and assumptions affect the reported amounts of assets and
liabilities and 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 estimates.

L. Reclassifications.

         We have reclassified certain financial statement items for 1998 and
1997 to conform with the 1999 presentation.


2.  Regulatory Matters

         Our utility operations are subject to regulation by the North Carolina
Utilities Commission (NCUC), the Public Service Commission of South Carolina
(PSCSC) and the Tennessee Regulatory Authority (TRA) as to rates, service area,
adequacy of service, safety standards, extensions and abandonment of facilities,
accounting and depreciation. We are also subject to regulation by the NCUC as to
the issuance of securities.

         We have been operating in an unbundled environment with all of our
interstate pipelines for several years under Federal Energy Regulatory
Commission (FERC) Order 636. In our opinion, present rules and regulations of
the NCUC, the PSCSC and the TRA permit the pass through to customers of
interstate pipeline capacity and storage service costs that may be incurred
under Order 636. Through 1999, the Company has recovered substantially all such
costs through purchased gas adjustment procedures.

         In 1996, the NCUC ordered us to establish an expansion fund and
approved initial funding with supplier refunds due customers to enable the
extension of natural gas service into unserved areas of the state. As of October
31, 1999, the North Carolina State Treasurer held $30,500,000 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 November 1998, the NCUC issued an order approving our request for an
expansion project to extend natural gas service to the counties of Avery,
Mitchell and Yancey. We requested



                                       32
<PAGE>   35

authority to use $26,300,000 in expansion fund money to pay a portion of the
estimated cost of the project of $31,900,000. In January 1999, we filed an
affidavit with the NCUC proposing an alternate route for the pipeline to these
counties at an additional cost of $1,500,000. In May 1999, the NCUC approved the
transfer of an additional $1,500,000 in supplier refunds to our expansion fund.
This provides funding of $27,800,000 for the project, now estimated to cost
$33,400,000.

         In December 1999, we filed with the TRA for a general rate increase of
$10,688,000 annually. The case is expected to be set for hearing in early 2000.


3.  Long-Term Debt

         Long-term debt at October 31, 1999 and 1998, is summarized as follows:

         Annual sinking fund requirements and maturities through 2004 are
$2,000,000 in 2000, $32,000,000 in 2001, $2,000,000 in 2002, $47,000,000 in 2003
and $2,000,000 in 2004.

         On September 15, 1999, we prepaid our 10.02% and 10.11% Senior Notes
due in 2003 and 2004, respectively, in the amount of $36,000,000 plus accrued
interest and an early payment premium of $1,100,000. The premium was deferred
and is being amortized over ten years. To fund this prepayment and for other
working capital and construction purposes, we issued two medium-term notes under
a shelf registration statement for $150,000,000 of debt



                                       33
<PAGE>   36

securities that was filed with the Securities and Exchange Commission in 1997.
These two medium-term notes consist of $30,000,000 of 7.35% notes due 2009 and
$60,000,000 of 7.95% notes due 2029. Both notes are to be redeemed in a single
payment at maturity.

         The amount of cash dividends that may be paid on Common Stock is
restricted by provisions contained in our articles of incorporation and in note
agreements under which long-term debt was issued. At October 31, 1999, all
retained earnings were free of such restrictions.

5.       Financial Instruments and Related Fair Value

         Various banks provide lines of credit totaling $75,000,000 to finance
current cash requirements. Additional lines are also available on an as needed,
if available, basis. These short-term borrowings under the lines, with maturity
dates of less than 90



                                       34
<PAGE>   37

days, include bankers' acceptances, transactional borrowings and overnight
cost-plus loans based on the lending bank's cost of money, with a maximum rate
of the lending bank's commercial prime interest rate. At October 31, 1999, the
lines of credit were on either a fee basis or compensating balance basis, with
average annual balance requirements of $300,000.

         At October 31, 1999, outstanding notes payable consisted of $50,000,000
in bankers' acceptances and $29,500,000 in overnight cost-plus loans. The
weighted average interest rate on such borrowings was 5.63%.

         Our principal business activity is the sale and transportation of
natural gas to customers located in North Carolina, South Carolina and
Tennessee. At October 31, 1999, gas receivables totaled $23,867,000 and other
receivables totaled $9,103,000. The uncollected balance of installment
receivables which have been transferred with recourse was $18,699,000 and
$20,969,000 at October 31, 1999 and 1998, respectively. We have provided an
adequate allowance for any receivables which may not be ultimately collected,
including the receivables transferred with recourse.

         During 1999, we made equity contributions to our subsidiary, Piedmont
Energy Company (Piedmont Energy), who is a member of SouthStar Energy Services
LLC (SouthStar). Piedmont Energy used these equity contributions to make loans
to SouthStar in accordance with a loan agreement between SouthStar and its
members. Loans are funded by the members based on ownership percentage and our
loans are limited to $22,500,000. Interest is charged on the outstanding
principal balance of each loan at an annual fixed rate equal to LIBOR plus 85
basis points with interest payable quarterly. All loans mature on June 27, 2000.

         At October 31, 1999, SouthStar owed Piedmont Energy $22,354,000,
including accrued interest. Piedmont Energy received $265,000 as interest earned
on the loans for the twelve months ended October 31, 1999.

         The carrying amounts in the consolidated balance sheets of cash and
cash equivalents, restricted cash, receivables, notes payable and accounts
payable approximated their fair values due to the short-term maturities of these
financial instruments. Based on quoted market prices of similar issues having
the same remaining maturities, redemption terms and credit ratings, the
estimated fair values of long-term debt at October 31, 1999 and 1998, including
current portion, were as follows:

</TABLE>

         The use of different market assumptions or estimation methodologies may
have a material effect on the estimated fair values. The fair value amounts are
not intended to reflect principal amounts that we will ultimately be required to
pay.

         We engage in minimal derivative products activities, such as
exchange-traded futures and over-the-counter forward contracts, to manage
commodity price and basis risk when appropriate. The hedging activities permit
us to translate physical market activities into a common pricing index against
which transaction values will be measured at the margin. Under internal
guidelines, we utilize limited speculative positions in the derivatives market
or in the form of fixed-price gas supply contracts. Our derivative products
activity is not material to financial position or results of operations.

         SouthStar enters into derivative instruments to hedge its exposure to
the impact of price and basis fluctuations on gas contracts and utilizes a
balanced book approach for matching sales to customers and supply from third
parties. Market risk is managed through adherence to open position limits,
signature authorizations and day-to-day commercial procedures maintained by
SouthStar. Risk of loss is mitigated by continually assessing such risks in the
context of the business and the structure of deals. All hedge transactions are
subject to a risk management policy, approved by SouthStar's Board of Directors,
which does not permit speculative positions. SouthStar's derivative products
activity is not material to our financial position or results of operations.


6. Employee Benefit Plans

         We have a defined-benefit pension plan for the benefit of substantially
all full-time regular employees. Plan benefits are generally based on credited
years of service and the level of compensation during the five consecutive years
of the last ten years prior to retirement during which the participant received
the highest compensation. Our policy is to fund the plan in an amount not in
excess of the amount that is deductible for income tax purposes. Plan assets
consist primarily of marketable securities and cash equivalents. We amend the
plan from time to time in accordance with changes in tax law.



                                       36
<PAGE>   39

         We provide certain postretirement health care and life insurance
benefits to substantially all full-time regular employees. As of October 31,
1999, the liability associated with such benefits was funded in irrevocable
trust funds which can only be used to pay the benefits.

         A reconciliation of the changes in the plans' benefit obligations and
fair value of assets for the years ended October 31, 1999 and 1998, and a
statement of the funded status as of October 31, 1999 and 1998, are presented

         We amortize unrecognized prior-service cost over the average remaining
service period for active employees. We amortize the unrecognized net transition
asset over the average remaining service period for active employees expected to
receive benefits under the plan as of the date of transition. We amortize gains
and losses in excess of 10% of the greater of the benefit obligation and the
market-related value of assets over the average remaining service period of
active employees. The method of amortization in all cases is straight-line.

obligation as of October 31, 1999, 1998 and 1997, are presented below:

         The assumed health care cost trend rate used in measuring the

2000, declining gradually to 4% in 2005 and remaining at that level thereafter.
The health care cost trend rate assumption has a significant effect on the

trend rates would have the following effects:

         We maintain salary investment plans which are profit-sharing plans
under Section 401(a) of the Internal Revenue Code of 1986, as amended (the Tax
Code), which include qualified cash or deferred arrangements under Tax Code
Section 401(k). Employees who have completed six months of service are eligible
to participate. Participants are permitted to defer a portion of their base
salary to the plans and we match a portion of the participants' contributions.
All contributions vest immediately. For the years ended October 31, 1999, 1998
and 1997, we contributed $2,298,000, $2,135,000 and $2,172,000, respectively, in
matching contributions to the plans.

8.  Business Segments and Other Non-Utility Activities

         We adopted SFAS No. 131, "Disclosures about Segments of an Enterprise
and Related Information", in 1999. The statement requires that operating
segments be reported on the basis that is used internally by the chief operating
decision maker in making decisions related to resource allocation and segment
performance. We have one reportable segment, domestic natural gas distribution.
Our reportable segment is operated and managed as three strategic business units
and is organized based on products and services and regulatory environments.

         Our domestic natural gas distribution business is conducted through the
following three companies:

         -        Piedmont Natural Gas Company, the parent company, is primarily
                  engaged in the sale and transportation of natural gas to
                  residential, commercial and industrial customers in the
                  Piedmont region of North Carolina and South Carolina and the
                  metropolitan Nashville, Tennessee, area.
         -        Piedmont Intrastate Pipeline Company, a wholly owned
                  subsidiary, is a 36% member of Cardinal Pipeline Company,
                  L.L.C. (Cardinal), a North Carolina limited liability company.
                  Cardinal owns and operates a natural gas pipeline from a
                  connection with an interstate pipeline to facilities owned by
                  us and facilities owned by another utility company who is also
                  a member. Because our investment is treated as utility assets
                  for ratemaking purposes, we include our share of the assets
                  and operations of Cardinal in utility operations.
         -        Piedmont Interstate Pipeline Company, a wholly owned
                  subsidiary, is a 35% member of Pine Needle LNG Company, L.L.C.
                  (Pine Needle), a North Carolina limited liability company.
                  Pine Needle owns a liquified natural gas (LNG) peak-demand
                  facility in North Carolina from which peaking service began in
                  May 1999. Storage capacity is four billion cubic feet with
                  vaporization capability of 400 million cubic feet per day. We
                  subscribe to one-half of this capacity to provide gas for
                  peak-use periods when demand is the highest. We made an equity
                  contribution of $18,725,000 to Pine Needle in 1999 to cover
                  our portion of the permanent financing of the facility.

         In 1995, the two members of Cardinal along with another utility company
and an interstate pipeline formed Cardinal Extension Company, L.L.C. (Cardinal
Extension), a North Carolina limited liability company, to extend the existing
Cardinal pipeline by approximately 67 miles. Effective November 1, 1999,



                                       41
<PAGE>   44

the new facilities were placed in service and Cardinal was merged into Cardinal
Extension with the surviving entity named Cardinal Pipeline Company, L.L.C. Our
investment in Cardinal was transferred to the new entity and our percentage
membership in the new entity is approximately 16%. Effective November 1, 1999,
our investment is no longer treated as utility assets for ratemaking purposes
and our share of the assets and operations of Cardinal will be accounted for in
non-utility operations.

         The accounting policies of our domestic natural gas distribution
segment are described in the summary of significant accounting policies in Note
1. Performance is evaluated based on margin, operations and maintenance
expenses, operating income and income before taxes. All of our operations are
within the United States. No single customer's revenues exceeded 10% or more of
our consolidated revenues.

         All of our other activities are included in Other in the segment tables
and consist of the following:

         -        Piedmont Propane Company, a wholly owned subsidiary, markets
                  propane and propane appliances to residential, commercial and
                  industrial customers within and adjacent to our three-state
                  natural gas service area.
         -        Piedmont Energy Company (Piedmont Energy), a wholly owned
                  subsidiary, has an equity interest in SouthStar Energy
                  Services LLC (SouthStar), a Delaware limited liability
                  company. SouthStar offers a combination of unregulated energy
                  products and services to industrial, commercial and
                  residential customers in the southeastern United States. These
                  products and services include natural gas, electricity, fuel
                  oil and propane, along with related services. Prior to July
                  1998, Piedmont Energy was a 51% member of Resource Energy
                  Services Company, L.L.C. (Resource Energy), a North Carolina
                  limited liability company. Resource Energy offered natural gas
                  acquisition, transportation and storage services to industrial
                  users and other utilities in the southeastern, mid-Atlantic
                  and midwestern regions of the United States.

         Continuing operations by segment for the years ended October 31, 1999,
1998 and 1997, are presented below:

9.  Environmental Matters

         We have owned, leased or operated manufactured gas plant (MGP)
facilities at 12 sites in our three-state service area. In 1997, we entered into
a settlement with a third party with respect to nine of these sites. As of
October 31, 1999, we had an environmental liability of $1,360,000 for the
remaining three MGP sites not covered by the settlement. This liability is
estimated based on a generic MGP site study as we have not performed
site-specific evaluations.

         Our three state regulatory commissions authorized us to utilize
deferral accounting, or to create a regulatory asset, for expenditures made in
connection with environmental matters. In connection with the settlement noted
above and the estimated liability for the three remaining sites, we have
recorded a regulatory asset of $6,610,000. As of October 31, 1999, we had an
additional regulatory asset in the amount of $377,000, net of recoveries from
customers, for other environmental costs, primarily legal fees and engineering
assessments.

         Further evaluations of the three remaining sites could significantly
affect recorded amounts; however, we believe that the ultimate resolution of
these matters will not have a material adverse effect on financial position or
results of operations.

MANAGEMENT'S RESPONSIBILITY FOR FINANCIAL REPORTING

         The management of Piedmont Natural Gas Company is responsible for the
preparation and integrity of the accompanying consolidated financial statements
and related notes. We prepared the statements in conformity with generally
accepted accounting principles appropriate in the circumstances and included
amounts which are necessarily based on our best estimates and judgments made
with due consideration to materiality. Financial information presented elsewhere
in this report is consistent with that in the financial statements.

         We have established and are responsible for maintaining a comprehensive
system of internal accounting controls which we believe provides reasonable
assurance that policies and procedures are complied with, assets are safeguarded
and transactions are executed according to management's authorization. We
continually review this system for effectiveness and modify it in response to
changing business conditions and operations and as a result of recommendations
by internal and external auditors.

         The Audit Committee of the Board of Directors, consisting solely of
outside Directors, meets periodically with Deloitte & Touche LLP, the internal
auditors and representatives of management to discuss auditing and financial
reporting matters. The Audit Committee reviews audit plans and results and
accounting, financial reporting and internal control practices, procedures and
results. Both Deloitte & Touche LLP and the internal auditors have full and free
access to all levels of management.

INDEPENDENT AUDITORS' REPORT

Piedmont Natural Gas Company, Inc.

         We have audited the accompanying consolidated balance sheets of
Piedmont Natural Gas Company, Inc. and subsidiaries (the Company) as of October
31, 1999 and 1998, and the related statements of consolidated income, retained
earnings and cash flows for each of the three years in the period ended October
31, 1999. Our audits also included the supplemental consolidated financial
statement schedule listed in Item 14. These financial statements and financial
statement schedule are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements and
financial statement schedule 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 October 31,
1999 and 1998, and the results of its operations and its cash flows for each of
the three years in the period ended October 31, 1999 in conformity with
generally accepted accounting principles. Also, in our opinion, such
consolidated financial statement schedule, when considered in relation to the
basic consolidated financial statements taken as a whole, presents fairly in all
material respects the information set forth therein.

         The pattern of quarterly earnings is the result of the highly seasonal
nature of the business as variations in weather conditions generally result in
greater earnings during the winter months. Basic earnings per share are
calculated using the weighted average number of shares outstanding during the
quarter. The annual amount may differ from the total of the quarterly amounts
due to changes in the number of shares outstanding during the year.


Item 9. Changes in and Disagreements with Accountants on Accounting and
Financial Disclosure

relationship with the Corporation; and

         2. Base Salary. The Corporation shall pay the Officer during the term
of this Agreement as compensation for all services rendered by him to the
Corporation a base salary in such amounts and at such intervals as shall be
commensurate with his duties and responsibilities hereunder. Initially such base

shall consider the overall performance of the Officer and the service of the
Officer rendered to the Corporation and its subsidiaries and changes in the cost
of living. The Board of Directors may also provide for performance or merit
increases. Participation by Officer in any incentive, deferred compensation,
stock option, stock purchase, bonus, pension, life insurance or other employee
benefit plans which may be offered by the Corporation from time to time and
participation in any fringe benefits provided by the Corporation shall not cause
a reduction of the base salary payable to the Officer. The Officer will be
entitled to such customary fringe benefits, vacation and sick leave as are
consistent with the normal practices and established policies of the
Corporation.

         3. Participation in Incentive, Retirement and Employee Benefit Plans;
Fringe Benefits. The Officer shall be entitled to participate in any plan
relating to incentive compensation, stock options, stock purchase, pension,
thrift, profit sharing, group life insurance, medical coverage, disability
coverage, education, or other retirement or employee benefits that the
Corporation has adopted, or may from time to time adopt, for the benefit of its
executive employees and for employees generally, subject to the eligibility
rules of such plans.

         The Officer shall also be entitled to participate in any other fringe
benefits which are now or may be or become applicable to the Corporation's
executive employees, including the payment of reasonable expenses for attending
annual and periodic meetings of trade associations, and any other benefits which
are commensurate with the duties and responsibilities to be performed by the
Officer under this Agreement. Additionally, the Officer shall be entitled to
such vacation and sick leave as shall be established under uniform employee
policies promulgated by the Board of Directors. The Corporation shall reimburse
the Officer for all out-of-pocket reasonable and necessary business expenses
which the Officer may incur in connection with his service on behalf of the
Corporation.

         4. Term. The initial term of employment under this Agreement shall be

party advising the other party that this Agreement is not to be further

the Officer agrees he will not, own, manage, operate, join, control or
participate in the management, operation or control of, or be employed by or
connected in any manner with any business which competes with the Corporation or
any of its subsidiary corporations without the prior written consent of the
Corporation. Notwithstanding the foregoing, the Officer shall be free, without
such consent, to purchase or hold as an investment or otherwise, up to five
percent of the outstanding stock or other securities of any corporation which
has its securities publicly traded on any recognized securities exchange or in
any established over-the-counter market.

                  The Officer shall hold in confidence all knowledge or
information of a confidential nature with respect to the business of the
Corporation or any subsidiary of the Corporation received by him during the term
of this Agreement and will not disclose or make use of such information without

ascertain the amount of monetary damages in the event of a breach by the Officer
under the provisions of this Section 5 and agrees that, in the event of a breach
of this Section, injunctive relief enforcing the terms of this Section is an
appropriate remedy.

under this Agreement in accordance with such reasonable standards expected of
employees with comparable positions in comparable organizations and as may be
established from time to time by the Board of Directors. The Corporation will

executives and necessary for him to perform his duties.

         7. Termination and Termination Pay.

                  (a) Change of Control. Following a Change in Control and
during the term of the Severance Agreement, this Agreement shall become null and
void except with respect to any rights or obligations accruing prior to the
Change in Control and the rights and obligations of the Officer and the Company,
including any termination of the Officer, shall be subject to the provisions of
the Severance Agreement.

                  (b) By Death. The Officer's employment under this Agreement
shall be terminated upon the death of the Officer during the term of this
Agreement, in which event the Officer's estate shall be entitled to receive all
compensation due the Officer through the last day of the calendar month in which
his death shall have occurred.

                  (c) By Total Disability. Except for that period of time
following a Change in Control and during the term of the Severance Agreement,
the Officer's employment under this Agreement shall be terminated upon the total
permanent disability of the Officer during the term of this Agreement, in which
event the Officer shall receive all compensation, including bonuses, through the
date of determination of such disability and for a period of 90 days thereafter.
For purposes of this Section, the Officer shall be deemed to have suffered
permanent disability upon the determination of such status by the United States
Social Security Administration or a certification to such effect by the
Officer's regular physician.

                  (d) By Officer. Except as provided in Section 4 of the
Severance Agreement, the Officer's employment under this Agreement may be
terminated at any time by the Officer upon 60 days' written notice to the Board
of Directors. Upon such termination, the Officer shall be entitled to receive
all compensation, including bonuses, through the effective date of such
termination.

                  (e) By Corporation. Except for that period of time following a
Change of Control and during the term of the Severance Agreement, the Board of
Directors may terminate the Officer's employment at any time, but any such
termination by the Board of Directors, other than termination for cause, shall
not prejudice the Officer's right to continue to receive payment of all
compensation and the continuance of benefits for a period of 12 months from the
effective date of termination or until such time as the Officer reaches 65 years
of age (whichever is less) as provided below. The Officer shall have no right to
receive compensation or other benefits (other than vested benefits) for any
period after termination for "cause." Termination for cause shall mean
termination because of the Officer's personal dishonesty, incompetence, willful
material misconduct, breach of fiduciary duty involving personal profit,
intentional failure to perform stated duties, willful material violation of an
law, rule or regulation (other than traffic or traffic-related violations or
similar offenses) or final cease-and-desist order, or material breach of any
provisions of this Agreement.

                  (f) Costs and Expenses. In the event any dispute shall arise
between the Officer and the Corporation as to the terms or interpretation of
this Agreement, including this Section 7, whether instituted by formal legal
proceedings or otherwise, including any action taken by Officer to enforce the
terms of this Section 7 or in defending against any action taken by the
Corporation, the Corporation shall reimburse the Officer for all costs and
expenses, proceedings or actions in the event the Officer prevails in any such
action.

         8. Successors and Assigns.

                  (a) This Employment Agreement shall inure to the benefit of
and be binding upon any corporate or other successor of the Corporation which
shall acquire, directly or indirectly, by conversion, merger, consolidation,
purchase or otherwise, all or substantially all of the assets of the
Corporation.

                  (b) Since the Corporation is contracting for the unique and
personal skills of the Officer, the Officer shall be precluded from assigning or
delegating his rights or duties hereunder without first obtaining the written
consent of the Corporation.

         9. Modification; Waiver; Amendments. No provision of this Agreement may
be modified, waived or discharged unless such waiver, modification or discharge
is agreed to in writing, signed by the Officer and on behalf of the Corporation
by such Officer as may be specifically designated by the Board of Directors. No
waiver by either party hereto at any time of any breach by the other party
hereto of, or compliance with, any condition or provision of this Agreement to
be performed by such other party shall be deemed a waiver of similar or
dissimilar provisions or conditions at the same or at any prior or subsequent
time. No amendments or additions to this Agreement shall be binding unless in
writing and signed by both parties, except as herein otherwise provided. Any
modification, waiver or amendment shall be made consistent with the terms and
conditions of the Severance Agreement.

                  The Officer shall hold in confidence all knowledge or
information of a confidential nature with respect to the business of the
Corporation or any subsidiary of the Corporation received by him during the term
of this Agreement and will not disclose or make use of such information without
the prior written consent of the Corporation.

                  The Officer acknowledges that it would not be possible to
ascertain the amount of monetary damages in the event of a breach by the Officer
under the provisions of this Section 5 and agrees that, in the event of a breach
of this Section, injunctive relief enforcing the terms of this Section is an
appropriate remedy.

         6. Standards. The Officer shall perform his duties and responsibilities
under this Agreement in accordance with such reasonable standards expected of
employees with comparable positions in comparable organizations and as may be
established from time to time by the Board of Directors. The Corporation will
provide the Officer with the working facilities and staff customary for similar
executives and necessary for him to perform his duties.

         7. Termination and Termination Pay.

                  (a) Change of Control. Following a Change in Control and
during the term of the Severance Agreement, this Agreement shall become null and
void except with respect to any rights or obligations accruing prior to the
Change in Control and the rights and obligations of the Officer and the Company,
including any termination of the Officer, shall be subject to the provisions of
the Severance Agreement.

                  (b) By Death. The Officer's employment under this Agreement
shall be terminated upon the death of the Officer during the term of this
Agreement, in which event the Officer's estate shall be entitled to receive all
compensation due the Officer through the last day of the calendar month in which

                  (c) By Total Disability. Except for that period of time

event the Officer shall receive all compensation, including bonuses, through the
date of determination of such disability and for a period of 90 days thereafter.
For purposes of this Section, the Officer shall be deemed to have suffered

                  (d) By Officer. Except as provided in Section 4 of the
Severance Agreement, the Officer's employment under this Agreement may be
terminated at any time by the Officer upon 60 days' written notice to the Board
of Directors. Upon such termination, the Officer shall be entitled to receive

                  (e) By Corporation. Except for that period of time following a
Change of Control and during the term of the Severance Agreement, the Board of
Directors may terminate the Officer's employment at any time, but any such
termination by the Board of Directors, other than termination for cause, shall
not prejudice the Officer's right to continue to receive payment of all
compensation and the continuance of benefits for a period of 12 months from the
effective date of termination or until such time as the Officer reaches 65 years
of age (whichever is less) as provided below. The Officer shall have no right to
receive compensation or other benefits (other than vested benefits) for any
period after termination for "cause." Termination for cause shall mean
termination because of the Officer's personal dishonesty, incompetence, willful
material misconduct, breach of fiduciary duty involving personal profit,
intentional failure to perform stated duties, willful material violation of an
law, rule or regulation (other than traffic or traffic-related violations or
similar offenses) or final cease-and-desist order, or material breach of any
provisions of this Agreement.

                  (f) Costs and Expenses. In the event any dispute shall arise
between the Officer and the Corporation as to the terms or interpretation of
this Agreement, including this Section 7, whether instituted by formal legal
proceedings or otherwise, including any action taken by Officer to enforce the
terms of this Section 7 or in defending against any action taken by the
Corporation, the Corporation shall reimburse the Officer for all costs and
expenses, proceedings or actions in the event the Officer prevails in any such
action.

         8. Successors and Assigns.

                  (a) This Employment Agreement shall inure to the benefit of
and be binding upon any corporate or other successor of the Corporation which
shall acquire, directly or indirectly, by conversion, merger, consolidation,
purchase or otherwise, all or substantially all of the assets of the
Corporation.

                  (b) Since the Corporation is contracting for the unique and
personal skills of the Officer, the Officer shall be precluded from assigning or
delegating his rights or duties hereunder without first obtaining the written
consent of the Corporation.

         9. Modification; Waiver; Amendments. No provision of this Agreement may
be modified, waived or discharged unless such waiver, modification or discharge
is agreed to in writing, signed by the Officer and on behalf of the Corporation
by such Officer as may be specifically designated by the Board of Directors. No
waiver by either party hereto at any time of any breach by the other party
hereto of, or compliance with, any condition or provision of this Agreement to
be performed by such other party shall be deemed a waiver of similar or
dissimilar provisions or conditions at the same or at any prior or subsequent
time. No amendments or additions to this Agreement shall be binding unless in
writing and signed by both parties, except as herein otherwise provided. Any
modification, waiver or amendment shall be made consistent with the terms and

                              W I T N E S S E T H:

         WHEREAS, the Board of Directors of the Corporation has determined that
the continued retention of the services of the Officer on a long-term basis as
described herein is in the best interest of the corporation in that (a) it
promotes the stability of senior management of the Corporation; (b) it enables

         WHEREAS, the services of the Officer, his experience and knowledge of
the affairs of the Corporation, and his reputation and contacts in the
Corporation's industry are extremely valuable to the Corporation; and

         WHEREAS, the Corporation considers the establishment and maintenance of
a sound and vital management to be part of its overall corporate strategy and to
be essential to protecting and enhancing the best interests of the Corporation
and its stockholders; and

         WHEREAS, the parties desire to enter into this Agreement in order to
clearly set forth the terms and conditions of the Officer's employment
relationship with the Corporation; and

         WHEREAS, contemporaneous with this Agreement, the parties have entered
into a Severance Agreement (the "Severance Agreement"), which sets forth certain
rights and obligations of the Officer and certain rights and obligations of the
Corporation in the event of a "Potential Change of Control" (as defined in the
Severance Agreement) or following a "Change in Control" (as defined in the
Severance Agreement). Use of the phrases "Potential Change of Control" and
"Change in Control" herein shall have the meanings ascribed to those phrases in

         NOW, THEREFORE, in consideration of the premises and mutual covenants
herein contained, the parties hereby agree as follows:

         1. Employment. The Corporation hereby employs the Officer and the
Officer hereby accepts such employment, upon the terms and conditions stated
herein, as President of the Corporation. The Officer shall render such
administrative and management services to the Corporation as are customarily
performed by persons situated in a similar executive capacity. The Officer shall

         2. Base Salary. The Corporation shall pay the Officer during the term
of this Agreement as compensation for all services rendered by him to the
Corporation a base salary in such amounts and at such intervals as shall be
commensurate with his duties and responsibilities hereunder. Initially such base

be increased from time to time to reflect the duties required of the Officer. In
reviewing the Officer's base salary, the Board of Directors of the Corporation
shall consider the overall performance of the Officer and the service of the
Officer rendered to the Corporation and its subsidiaries and changes in the cost
of living. The Board of Directors may also provide for performance or merit
increases. Participation by Officer in any incentive, deferred compensation,
stock option, stock purchase, bonus, pension, life insurance or other employee
benefit plans which may be offered by the Corporation from time to time and
participation in any fringe benefits provided by the Corporation shall not cause
a reduction of the base salary payable to the Officer. The Officer will be
entitled to such customary fringe benefits, vacation and sick leave as are
consistent with the normal practices and established policies of the
Corporation.

         3. Participation in Incentive, Retirement and Employee Benefit Plans;

relating to incentive compensation, stock options, stock purchase, pension,
thrift, profit sharing, group life insurance, medical coverage, disability
coverage, education, or other retirement or employee benefits that the
Corporation has adopted, or may from time to time adopt, for the benefit of its
executive employees and for employees generally, subject to the eligibility
rules of such plans.

         The Officer shall also be entitled to participate in any other fringe
benefits which are now or may be or become applicable to the Corporation's
executive employees, including the payment of reasonable expenses for attending
annual and periodic meetings of trade associations, and any other benefits which
are commensurate with the duties and responsibilities to be performed by the
Officer under this Agreement. Additionally, the Officer shall be entitled to
such vacation and sick leave as shall be established under uniform employee
policies promulgated by the Board of Directors. The Corporation shall reimburse
the Officer for all out-of-pocket reasonable and necessary business expenses
which the Officer may incur in connection with his service on behalf of the
Corporation.

         4. Term. The initial term of employment under this Agreement shall be
for a two-year period commencing December 1, 1999; provided that this Agreement
shall automatically be extended to a full one-year period on each successive day
during the term of this Agreement. The effect hereof shall be that the Agreement
shall at all times remain subject to a term of one year, unless (i) written
notice has been given that the Agreement shall not be extended as provided in
this Section 4, or (ii) the Agreement is terminated pursuant to Section 7. If
written notice from the Corporation or the Officer is delivered to the other
party advising the other party that this Agreement is not to be further
extended, then upon such notice, the Agreement shall terminate on the second
anniversary of the date of notice. Provided, further, no extension shall cause
this Agreement to extend beyond the date on which the Officer reaches 65 years
of age. Upon any extension, the base salary of the extended agreement shall be

annual and periodic meetings of trade associations, and any other benefits which
are commensurate with the duties and responsibilities to be performed by the
Officer under this Agreement. Additionally, the Officer shall be entitled to
such vacation and sick leave as shall be established under uniform employee
policies promulgated by the Board of Directors. The Corporation shall reimburse
the Officer for all out-of-pocket reasonable and necessary business expenses
which the Officer may incur in connection with his service on behalf of the
Corporation.

         4. Term. The initial term of employment under this Agreement shall be
for a one-year period commencing December 1, 1999; provided that this Agreement
shall automatically be extended to a full one-year period on each successive day
during the term of this Agreement. The effect hereof shall be that the Agreement
shall at all times remain subject to a term of one year, unless (i) written
notice has been given that the Agreement shall not be extended as provided in
this Section 4, or (ii) the Agreement is terminated pursuant to Section 7. If
written notice from the Corporation or the Officer is delivered to the other
party advising the other party that this Agreement is not to be further
extended, then upon such notice, the Agreement shall terminate on the second
anniversary of the date of notice. Provided, further, no extension shall cause
this Agreement to extend beyond the date on which the Officer reaches 65 years
of age. Upon any extension, the base salary of the extended agreement shall be
the base salary in effect on the effective date of such extension.

         5. Loyalty; Noncompetition

                  (a) The Officer shall devote his best efforts to the
performance of his duties and responsibilities under this Agreement.

                  (b) During the term of this Agreement, or any renewals hereof,
the Officer agrees he will not, own, manage, operate, join, control or
participate in the management, operation or control of, or be employed by or
connected in any manner with any business which competes with the Corporation or
any of its subsidiary corporations without the prior written consent of the
Corporation. Notwithstanding the foregoing, the Officer shall be free, without
such consent, to purchase or hold as an investment or otherwise, up to five
percent of the outstanding stock or other securities of any corporation which
has its securities publicly traded on any recognized securities exchange or in
any established over-the-counter market.

                  The Officer shall hold in confidence all knowledge or
information of a confidential nature with respect to the business of the
Corporation or any subsidiary of the Corporation received by him during the term
of this Agreement and will not disclose or make use of such information without
the prior written consent of the Corporation.

                  The Officer acknowledges that it would not be possible to
ascertain the amount of monetary damages in the event of a breach by the Officer
under the provisions of this Section 5 and agrees that, in the event of a breach
of this Section, injunctive relief enforcing the terms of this Section is an
appropriate remedy.

         6. Standards. The Officer shall perform his duties and responsibilities
under this Agreement in accordance with such reasonable standards expected of
employees with comparable positions in comparable organizations and as may be
established from time to time by the Board of Directors. The Corporation will
provide the Officer with the working facilities and staff customary for similar
executives and necessary for him to perform his duties.

         7. Termination and Termination Pay.

                  (a) Change of Control. Following a Change in Control and
during the term of the Severance Agreement, this Agreement shall become null and
void except with respect to any rights or obligations accruing prior to the
Change in Control and the rights and obligations of the Officer and the Company,
including any termination of the Officer, shall be subject to the provisions of
the Severance Agreement.

                  (b) By Death. The Officer's employment under this Agreement
shall be terminated upon the death of the Officer during the term of this
Agreement, in which event the Officer's estate shall be entitled to receive all
compensation due the Officer through the last day of the calendar month in which
his death shall have occurred.

                  (c) By Total Disability. Except for that period of time
following a Change in Control and during the term of the Severance Agreement,
the Officer's employment under this Agreement shall be terminated upon the total
permanent disability of the Officer during the term of this Agreement, in which
event the Officer shall receive all compensation, including bonuses, through the
date of determination of such disability and for a period of 90 days thereafter.
For purposes of this Section, the Officer shall be deemed to have suffered
permanent disability upon the determination of such status by the United States
Social Security Administration or a certification to such effect by the
Officer's regular physician.


                                       3
<PAGE>   4

                  (d) By Officer. Except as provided in Section 4 of the
Severance Agreement, the Officer's employment under this Agreement may be
terminated at any time by the Officer upon 60 days' written notice to the Board
of Directors. Upon such termination, the Officer shall be entitled to receive
all compensation, including bonuses, through the effective date of such
termination.

                  (e) By Corporation. Except for that period of time following a
Change of Control and during the term of the Severance Agreement, the Board of
Directors may terminate the Officer's employment at any time, but any such
termination by the Board of Directors, other than termination for cause, shall
not prejudice the Officer's right to continue to receive payment of all
compensation and the continuance of benefits for a period of 12 months from the
effective date of termination or until such time as the Officer reaches 65 years
of age (whichever is less) as provided below. The Officer shall have no right to
receive compensation or other benefits (other than vested benefits) for any
period after termination for "cause." Termination for cause shall mean
termination because of the Officer's personal dishonesty, incompetence, willful
material misconduct, breach of fiduciary duty involving personal profit,
intentional failure to perform stated duties, willful material violation of an
law, rule or regulation (other than traffic or traffic-related violations or
similar offenses) or final cease-and-desist order, or material breach of any
provisions of this Agreement.

                  (f) Costs and Expenses. In the event any dispute shall arise
between the Officer and the Corporation as to the terms or interpretation of
this Agreement, including this Section 7, whether instituted by formal legal
proceedings or otherwise, including any action taken by Officer to enforce the
terms of this Section 7 or in defending against any action taken by the
Corporation, the Corporation shall reimburse the Officer for all costs and
expenses, proceedings or actions in the event the Officer prevails in any such
action.

         8. Successors and Assigns.

                  (a) This Employment Agreement shall inure to the benefit of
and be binding upon any corporate or other successor of the Corporation which
shall acquire, directly or indirectly, by conversion, merger, consolidation,
purchase or otherwise, all or substantially all of the assets of the
Corporation.

                  (b) Since the Corporation is contracting for the unique and
personal skills of the Officer, the Officer shall be precluded from assigning or
delegating his rights or duties hereunder without first obtaining the written
consent of the Corporation.

         9. Modification; Waiver; Amendments. No provision of this Agreement may
be modified, waived or discharged unless such waiver, modification or discharge
is agreed to in writing, signed by the Officer and on behalf of the Corporation
by such Officer as may be specifically designated by the Board of Directors. No
waiver by either party hereto at any time of any breach by the other party
hereto of, or compliance with, any condition or provision of this Agreement to
be performed by such other party shall be deemed a waiver of similar or
dissimilar provisions or conditions at the same or at any prior or subsequent
time. No amendments or additions to this Agreement shall be binding unless in
writing and signed by both parties, except as herein otherwise provided. Any
modification, waiver or amendment shall be made consistent with the terms and
conditions of the Severance Agreement.

         10. Applicable Law. This Agreement shall be governed in all respects
whether as to validity, construction, capacity, performance or otherwise, by the
laws of North Carolina.

         11. Severability. The provision of this Agreement shall be deemed
severable and the invalidity or unenforceability of any provision shall not
affect the validity or enforceability of the other provisions hereof.

day and year first hereinabove written.

                               SEVERANCE AGREEMENT

         THIS AGREEMENT, dated December 1, 1999, is made by and between PIEDMONT
NATURAL GAS COMPANY, INC., a North Carolina corporation (the "Company"), and
DAVID J. DZURICKY (the "Executive").

         WHEREAS, the Company considers it essential to the best interests of
its shareholders to foster the continued employment of key management personnel;
and

         WHEREAS, the Board of the Company recognizes that, as is the case with
many publicly held corporations, the possibility of a Change in Control exists
and that such possibility, and the uncertainty and questions which it may raise
among management, may result in the departure or distraction of management
personnel to the detriment of the Company and its shareholders; and

         WHEREAS, the Board has determined that appropriate steps should be
taken to reinforce and encourage the continued attention and dedication of
members of the Company's management, including the Executive, to their assigned
duties without distraction in the face of potentially disturbing circumstances
arising from the possibility of a Change in Control; and

         WHEREAS, contemporaneous with this Agreement, the Company and the
Executive have entered into an Employment Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the Company and the Executive hereby agree as
follows:

         1. Defined Terms. The definitions of capitalized terms used in this
Agreement are provided in the last Section hereof.

         2. Term of Agreement. The Term of this Agreement shall commence on the
date hereof and shall continue in effect through December 31, 2001; provided,
however, that commencing on January 1, 2002 and each January 1 thereafter, the
Term shall automatically be extended for one additional year unless, not later
than fifteen (15) months prior to the applicable January 1, the Company or the
Executive shall have given notice not to extend the Term; and further provided,
however, that if a Change in Control shall have occurred during the Term, the
Term shall expire at the end of the thirty-sixth (36th) calendar month after the
calendar month in which such Change in Control occurred. For example, if a
Change in Control were to occur on July 1, 1999, the Term of this Agreement
would expire on June 30, 2002, and if a Change in Control were to occur on July
1, 2002, the Term of this Agreement would expire on June 30, 2005 (regardless of
whether on or before September 30, 2001 either party had given notice to the
other party not to extend the Term as provided above).

         3. Company's Covenants Summarized. In order to induce the Executive to
remain in the employ of the Company and in consideration of the Executive's
covenants set forth in Section 4 hereof, the Company agrees, under the
conditions described herein, to pay the Executive the Severance Payments and the
other payments and benefits described herein. Except as provided in Section 9.1
hereof, no Severance Payments shall be payable under this Agreement unless there
shall have been (or, under the terms of the second sentence of Section 6.1
hereof, there shall be deemed to have been) a termination of the Executive's
employment with the Company following a Change in Control and during the Term.
This Agreement shall not be construed as creating an express or implied contract
of employment and, except as otherwise agreed in writing between the Executive
and the Company, the Executive shall not have any right to be retained in the
employ of the Company.

         4. The Executive's Covenants. The Executive agrees that, subject to the
terms and conditions of this Agreement, in the event of a Potential Change in
Control during the Term, the Executive will remain in the employ of the Company
until the earliest of (i) a date which is twelve (12) months from the date of
such Potential Change of Control, (ii) the date of a Change in Control, (iii)
the date of termination by the Executive of the Executive's employment for Good
Reason or by reason of death, Disability or Retirement, or (iv) the termination
by the Company of the Executive's employment for any reason. Should the
Executive fail to comply with the provisions of this paragraph 4, the Company's
sole remedy shall be to deny the payment of any Severance Payments to the
Executive.

         5. Compensation Other Than Severance Payments.

                  5.1 Following a Change in Control and during the Term, during
any period that the Executive fails to perform the Executive's full-time duties
with the Company as a result of incapacity due to physical or mental illness,
the Company shall pay the Executive's full salary to the Executive at the rate
in effect at the commencement of any such period, together with all compensation
and benefits payable to the Executive under the terms of any compensation,
benefit or incentive plan, program or arrangement maintained by the Company
during such period, until the Executive's employment is terminated by the
Company for Disability.

                  5.2 If the Executive's employment shall be terminated for any
reason following a Change in Control and during the Term, the Company shall pay
the Executive's full salary to the Executive through the Date of Termination at
the rate in effect immediately prior to the Date of Termination or, if higher,
the rate in effect immediately prior to the first occurrence of an event or
circumstance constituting Good Reason, together with all compensation and
benefits payable to the Executive through the Date of Termination under the
terms of the Company's executive compensation, benefit and incentive plans,
programs or arrangements as in effect immediately prior to the Date of
Termination or, if more favorable to the Executive, as in effect immediately
prior to the first occurrence of an event or circumstance constituting Good
Reason.

<PAGE>   3

                  5.3 If the Executive's employment shall be terminated for any
reason following a Change in Control and during the Term, the Company shall pay
to the Executive the Executive's normal post-termination compensation and
benefits as such payments become due, including in a lump sum in cash that
portion of the Executive's vacation pay vested and accrued but not paid. Such
post-termination compensation and benefits shall be determined under, and paid
in accordance with, the Company's long-term incentive stock plan, pension,
supplemental retirement, insurance and other executive compensation, benefit or
incentive plans, programs and arrangements as in effect immediately prior to the
Date of Termination or, if more favorable to the Executive, as in effect
immediately prior to the occurrence of the first event or circumstance
constituting Good Reason.

         6. Severance Payments.

                  6.1 Subject to Section 6.2 hereof, if the Executive's
employment is terminated following a Change in Control and during the Term,
other than (A) by the Company for Cause, (B) by reason of death or Disability,
or (C) by the Executive without Good Reason (including Retirement by the
Executive), then the Company shall pay the Executive the amounts, and provide
the Executive the benefits, described in this Section 6.1 ("Severance
Payments"), in addition to any payments and benefits to which the Executive is
entitled under Section 5 hereof. For purposes of this Agreement, the Executive's
employment shall be deemed to have been terminated following a Change in Control
by the Company without Cause or by the Executive with Good Reason, if (i) the
Executive's employment is terminated by the Company without Cause prior to a
Change in Control (whether or not a Change in Control ever occurs) and such
termination was at the request or direction of a Person who has entered into an
agreement with the Company the consummation of which would constitute a Change
in Control, (ii) the Executive terminates his employment for Good Reason prior
to a Change in Control (whether or not a Change in Control ever occurs) and the
circumstance or event which constitutes Good Reason occurs at the request or
direction of such Person, or (iii) the Executive's employment is terminated by
the Company without Cause or by the Executive for Good Reason and such
termination or the circumstance or event which constitutes Good Reason is
otherwise in connection with or in anticipation of a Change in Control (whether
or not a Change in Control ever occurs). For purposes of any determination
regarding the applicability of the immediately preceding sentence, any position
taken by the Executive shall be presumed to be correct unless the Company
establishes by clear and convincing evidence that such position is not correct.

                           (A) In lieu of any further salary payments to the
Executive for periods subsequent to the Date of Termination and in lieu of any
severance benefit otherwise payable to the Executive, the Company shall pay to
the Executive a lump sum severance payment, in cash, equal to 3.00 times the sum
of (i) the Executive's annual base salary as in effect immediately prior to the
Date of Termination or, if higher, in effect immediately prior to the first
occurrence of an event or circumstance constituting Good Reason and (ii) an
amount equal to the average of the Executive's annual W-2 Compensation for the
three years ending on the last day of the month prior to the Date of
Termination.

                           (B) For the 36-month period immediately following the
Date of Termination, the Company shall arrange to provide the Executive and his
dependents life, disability, accident and health insurance benefits
substantially similar to those provided to the Executive and


                                       3
<PAGE>   4

his dependents immediately prior to the Date of Termination or, if more
favorable to the Executive, those provided to the Executive and his dependents
immediately prior to the first occurrence of an event or circumstance
constituting Good Reason, at no greater cost to the Executive than the cost to
the Executive immediately prior to such date or occurrence; provided, however,
that, unless the Executive consents to a different method (after taking into
account the effect of such method on the calculation of "parachute payments"
pursuant to Section 6.2 hereof), such health insurance benefits shall be
provided through a third-party insurer. Benefits otherwise receivable by the
Executive pursuant to this Section 6.1(B) shall be reduced to the extent
benefits of the same type are received by or made available to the Executive
during the 36-month period following the Executive's termination of employment
(and any such benefits received by or made available to the Executive shall be
reported to the Company by the Executive); provided, however, that the Company
shall reimburse the Executive for the excess, if any, of the cost of such
benefits to the Executive over such cost immediately prior to the Date of
Termination or, if more favorable to the Executive, the first occurrence of an
event or circumstance constituting Good Reason. If the Severance Payments shall
be decreased pursuant to Section 6.2 hereof, and the Section 6.1(B) benefits
which remain payable after the application of Section 6.2 hereof are thereafter
reduced pursuant to the immediately preceding sentence, the Company shall, no
later than five (5) business days following such reduction, pay to the Executive
the least of (a) the amount of the decrease made in the Severance Payments
pursuant to Section 6.2 hereof, (b) the amount of the subsequent reduction in
these Section 6.1(B) benefits, or (c) the maximum amount which can be paid to
the Executive without being, or causing any other payment to be, nondeductible
by reason of section 280G of the Code.

                  6.2 (A) Notwithstanding any other provisions of this
Agreement, in the event that any payment or benefit received or to be received
by the Executive in connection with a Change in Control or the termination of
the Executive's employment (whether pursuant to the terms of this Agreement or
any other plan, arrangement or agreement with the Company, any Person whose
actions result in a Change in Control or any Person affiliated with the Company
or such Person) (all such payments and benefits, including the Severance
Payments, being hereinafter called "Total Payments") would not be deductible (in
whole or part), by the Company, an affiliate or Person making such payment or
providing such benefit as a result of section 280G of the Code, then, to the
extent necessary to make such portion of the Total Payments deductible (and
after taking into account any reduction in the Total Payments provided by reason
of section 280G of the Code in such other plan, arrangement or agreement), the
cash Severance Payments shall first be reduced (if necessary, to zero), and all
other Severance Payments shall thereafter be reduced (if necessary, to zero);
provided, however, that the Executive may elect to have the noncash Severance
Payments reduced (or eliminated) prior to any reduction of the cash Severance
Payments.

                           (B) For purposes of this limitation, (i) no portion
of the Total Payments the receipt or enjoyment of which the Executive shall have
waived at such time and in such manner as not to constitute a "payment" within
the meaning of section 280G(b) of the Code shall be taken into account, (ii) no
portion of the Total Payments shall be taken into account which, in the opinion
of tax counsel ("Tax Counsel") reasonably acceptable to the Executive and
selected by the accounting firm which was, immediately prior to the Change in
Control, the Company's independent


                                       4
<PAGE>   5

auditor (the "Auditor"), does not constitute a "parachute payment" within the
meaning of section 280G(b)(2) of the Code, including by reason of section
280G(b)(4)(A) of the Code, (iii) the Severance Payments shall be reduced only to
the extent necessary so that the Total Payments (other than those referred to in
clauses (i) or (ii)) in their entirety constitute reasonable compensation for
services actually rendered within the meaning of section 280G(b)(4)(B) of the
Code or are otherwise not subject to disallowance as deductions by reason of
section 280G of the Code, in the opinion of Tax Counsel, and (iv) the value of
any noncash benefit or any deferred payment or benefit included in the Total
Payments shall be determined by the Auditor in accordance with the principles of
sections 280G(d)(3) and (4) of the Code.

                           (C) If it is established pursuant to a final
determination of a court or an Internal Revenue Service proceeding that,
notwithstanding the good faith of the Executive and the Company in applying the
terms of this Section 6.2, the Total Payments paid to or for the Executive's
benefit are in an amount that would result in any portion of such Total Payments
being subject to the Excise Tax, then, if such repayment would result in (i) no
portion of the remaining Total Payments being subject to the Excise Tax and (ii)
a dollar-for-dollar reduction in the Executive's taxable income and wages for
purposes of federal, state and local income and employment taxes, the Executive
shall have an obligation to pay the Company upon demand an amount equal to the
sum of (i) the excess of the Total Payments paid to or for the Executive's
benefit over the Total Payments that could have been paid to or for the
Executive's benefit without any portion of such Total Payments being subject to
the Excise Tax; and (ii) interest on the amount set forth in clause (i) of this
sentence at the rate provided in section 1274(b)(2)(B) of the Code from the date
of the Executive's receipt of such excess until the date of such payment.

                  6.3 The payments provided in subsection (A) of Section 6.1
hereof shall be made not later than the fifth day following the Date of
Termination; provided, however, that if the amounts of such payments, and the
limitation on such payments set forth in Section 6.2 hereof, cannot be finally
determined on or before such day, the Company shall pay to the Executive on such
day an estimate, as determined in good faith by the Company of the minimum
amount of such payments to which the Executive is clearly entitled and shall pay
the remainder of such payments (together with interest on the unpaid remainder
(or on all such payments to the extent the Company fails to make such payments
when due) at 120% of the rate provided in section 1274(b)(2)(B) of the Code) as
soon as the amount thereof can be determined but in no event later than the
thirtieth (30th) day after the Date of Termination. In the event that the amount
of the estimated payments exceeds the amount subsequently determined to have
been due, such excess shall constitute a loan by the Company to the Executive,
payable on the fifth (5th) business day after demand by the Company (together
with interest at 120% of the rate provided in section 1274(b)(2)(B) of the
Code). At the time that payments are made under this Agreement, the Company
shall provide the Executive with a written statement setting forth the manner in
which such payments were calculated and the basis for such calculations
including, without limitation, any opinions or other advice the Company has
received from Tax Counsel, the Auditor or other advisors or consultants (and any
such opinions or advice which are in writing shall be attached to the
statement).

         7. Termination Procedures and Compensation During Dispute.

                  7.1 Notice of Termination. After a Change in Control and
during the Term, any purported termination of the Executive's employment (other
than by reason of death) shall be communicated by written Notice of Termination
from one party hereto to the other party hereto in accordance with Section 10
hereof. For purposes of this Agreement, a "Notice of Termination" shall mean a
notice which shall indicate the specific termination provision in this Agreement
relied upon and shall set forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of the Executive's employment under
the provision so indicated. Further, a Notice of Termination for Cause is
required to include a copy of a resolution duly adopted by the affirmative vote
of not less than three-quarters (3/4) of the entire membership of the Board at a
meeting of the Board which was called and held for the purpose of considering
such termination (after reasonable notice to the Executive and an opportunity
for the Executive, together with the Executive's counsel, to be heard before the
Board) finding that, in the good faith opinion of the Board, the Executive was
guilty of conduct set forth in clause (i) or (ii) of the definition of Cause
herein, and specifying the particulars thereof in detail.

                  7.2 Date of Termination. "Date of Termination," with respect
to any purported termination of the Executive's employment after a Change in
Control and during the Term, shall mean (i) if the Executive's employment is
terminated for Disability, thirty (30) days after Notice of Termination is given
(provided that the Executive shall not have returned to the full-time
performance of the Executive's duties during such thirty (30) day period), and
(ii) if the Executive's employment is terminated for any other reason, the date
specified in the Notice of Termination (which, in the case of a termination by
the Company, shall not be less than thirty (30) days (except in the case of a
termination for Cause) and, in the case of a termination by the Executive, shall
not be less than fifteen (15) days nor more than sixty (60) days, respectively,
from the date such Notice of Termination is given).

                  7.3 Dispute Concerning Termination. If within fifteen (15)
days after any Notice of Termination is given, or, if later, prior to the Date
of Termination (as determined without regard to this Section 7.3), the party
receiving such Notice of Termination notifies the other party that a dispute
exists concerning the termination, the Date of Termination shall be extended
until the earlier of (i) the date on which the Term ends or (ii) the date on
which the dispute is finally resolved, either by mutual written agreement of the
parties or by a final judgment, order or decree of an arbitrator or a court of
competent jurisdiction (which is not appealable or with respect to which the
time for appeal therefrom has expired and no appeal has been perfected);
provided, however, that the Date of Termination shall be extended by a notice of
dispute given by the Executive only if such notice is given in good faith and
the Executive pursues the resolution of such dispute with reasonable diligence.

                  7.4 Compensation During Dispute. If a purported termination
occurs following a Change in Control and during the Term and the Date of
Termination is extended in accordance with Section 7.3 hereof, the Company shall
continue to pay the Executive the full compensation in effect when the notice
giving rise to the dispute was given (including, but not limited to, salary) and
continue the Executive as a participant in all compensation, benefit and
insurance plans in which the Executive was participating when the notice giving
rise to the dispute was given, until the Date of Termination, as determined in
accordance with Section 7.3 hereof. Amounts paid under this Section 7.4 are in
addition to all other amounts due under this Agreement (other than those due
under Section 5.2 hereof) and shall not be offset against or reduce any other
amounts due under this Agreement.

         8. No Mitigation. The Company agrees that, if the Executive's
employment with the Company terminates during the Term, the Executive is not
required to seek other employment or to attempt in any way to reduce any amounts
payable to the Executive by the Company pursuant to Section 6 hereof or Section
7.4 hereof. Further, the amount of any payment or benefit provided for in this
Agreement (other than Section 6.1(B) hereof) shall not be reduced by any
compensation earned by the Executive as the result of employment by another
employer, by retirement benefits, by offset against any amount claimed to be
owed by the Executive to the Company, or otherwise.

         9. Successors; Binding Agreement.

                  9.1 In addition to any obligations imposed by law upon any
successor to the Company, the Company will require any successor (whether direct
or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to expressly
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place. Failure of the Company to obtain such assumption and agreement
prior to the effectiveness of any such succession shall be a breach of this
Agreement and shall entitle the Executive to compensation from the Company in
the same amount and on the same terms as the Executive would be entitled to
hereunder if the Executive were to terminate the Executive's employment for Good
Reason after a Change in Control, except that, for purposes of implementing the
foregoing, the date on which any such succession becomes effective shall be
deemed the Date of Termination.

                  9.2 This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Executive shall die while any amount would still be payable to the Executive
hereunder (other than amounts which, by their terms, terminate upon the death of
the Executive) if the Executive had continued to live, all such amounts, unless
otherwise provided herein, shall be paid in accordance with the terms of this
Agreement to the executors, personal representatives or administrators of the
Executive's estate.

         10. Notices. For the purpose of this Agreement, notices and all other
communications provided for in the Agreement shall be in writing and shall be
deemed to have been duly given when delivered or mailed by United States
registered mail, return receipt requested, postage prepaid, addressed, if to the
Executive, to the address inserted below the Executive's signature on the final
page hereof and, if to the Company, to the address set forth below, or to such
other address as either


                                       7

party may have furnished to the other in writing in accordance herewith, except
that notice of change of address shall be effective only upon actual receipt:

                                    To the Company:

                                    Piedmont Natural Gas Company, Inc.
                                    P.O. Box 33068
                                    Charlotte, North Carolina 28233

                                    Attention: Corporate Secretary

         11. Miscellaneous. No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing and signed by the Executive and such officer as may be specifically
designated by the Board. No waiver by either party hereto at any time of any
breach by the other party hereto of, or of any lack of compliance with, any
condition or provision of this Agreement to be performed by such other party
shall be deemed a waiver of similar or dissimilar provisions or conditions at
the same or at any prior or subsequent time. This Agreement supersedes any other
agreements or representations, oral or otherwise, express or implied, with
respect to the subject matter hereof which have been made by either party;
provided, however, that this Agreement shall supersede any agreement setting
forth the terms and conditions of the Executive's employment with the Company
only in the event that the Executive's employment with the Company is terminated
on or following a Change in Control (i) by the Company other than for Cause or
(ii) by the Executive for Good Reason. The validity, interpretation,
construction and performance of this Agreement shall be governed by the laws of
the State of North Carolina. All references to sections of the Exchange Act or
the Code shall be deemed also to refer to any successor provisions to such
sections. Any payments provided for hereunder shall be paid net of any
applicable withholding required under federal, state or local law and any
additional withholding to which the Executive has agreed. The obligations of the
Company and the Executive under this Agreement which by their nature may require
either partial or total performance after the expiration of the Term (including,
without limitation, those under Sections 6 and 7 hereof) shall survive such
expiration.

         12. Validity. The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, which shall remain in full force and effect.

         13. Counterparts. This Agreement may be executed in several
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

         14. Settlement of Disputes; Arbitration.

                  14.1 All claims by the Executive for benefits under this
Agreement shall be directed to and determined by the Board and shall be in
writing. Any denial by the Board of a claim for benefits under this Agreement
shall be delivered to the Executive in writing and shall set forth the specific
reasons for the denial and the specific provisions of this Agreement relied
upon. The Board shall afford a reasonable opportunity to the Executive for a
review of the decision denying a claim and shall further allow the Executive to
appeal to the Board a decision of the Board within sixty (60) days after
notification by the Board that the Executive's claim has been denied.

                  14.2 Any further dispute or controversy arising under or in
connection with this Agreement shall be settled exclusively by arbitration in
Charlotte, North Carolina in accordance with the rules of the American
Arbitration Association then in effect; provided, however, that the evidentiary
standards set forth in this Agreement shall apply. Judgment may be entered on
the arbitrator's award in any court having jurisdiction. Notwithstanding any
provision of this Agreement to the contrary, the Executive shall be entitled to
seek specific performance of the Executive's right to be paid until the Date of
Termination during the pendency of any dispute or controversy arising under or
in connection with this Agreement.

<PAGE>   12

of the Executive's responsibilities from those in effect immediately prior to
the Change in Control other than any such alteration primarily attributable to
the fact that the Company may no longer be a public company;

                           (II) a reduction by the Company in the Executive's

arrangement (embodied in an ongoing substitute or alternative plan) has been
made with respect to such plan, or the failure by the Company to continue the

purported termination shall be effective.

                  The Executive's right to terminate the Executive's employment
for Good Reason shall not be affected by the Executive's incapacity due to
physical or mental illness. The Executive's continued employment shall not
constitute consent to, or a waiver of rights with respect to, any act or failure
to act constituting Good Reason hereunder.

                  For purposes of any determination regarding the existence of
Good Reason, any claim by the Executive that Good Reason exists shall be
presumed to be correct unless the Company establishes by clear and convincing
evidence that Good Reason does not exist.

                  (O) "Notice of Termination" shall have the meaning set forth
in Section 7.1 hereof.

                  (P) "Person" shall have the meaning given in Section 3(a)(9)

except that such term shall not include (i) the Company or any of its

underwriter temporarily holding securities pursuant to an offering of such

ownership of stock of the Company.

                  (Q) "Potential Change in Control" shall be deemed to have
occurred if the event set forth in any one of the following paragraphs shall
have occurred:

                           (I) the Company enters into an agreement, the
consummation of which would result in the occurrence of a Change in Control;

                           (II) the Company or any Person publicly announces an
intention to take or to consider taking actions which, if consummated, would
constitute a Change in Control;

                           (III) any Person becomes the Beneficial owner,
directly or indirectly, of securities of the Company representing 15% or more of
either the then outstanding shares of common stock of the Company or the
combined voting power of the Company's then outstanding securities (not
including in the securities beneficially owned by such Person any securities
acquired directly from the Company or its affiliates); or


                                       13
<PAGE>   14

                           (IV) the Board adopts a resolution to the effect
that, for purposes of this Agreement, a Potential Change in Control has
occurred.

                  (R) "Retirement" shall be deemed the reason for the
termination by the Executive of the Executive's employment if such employment is
terminated voluntarily by the Executive in accordance with the Company's
retirement policy, including early retirement, generally applicable to its
salaried employees.

                  (S) "Severance Payments" shall have the meaning set forth in

                  (U) "Term" shall mean the period of time described in Section
2 hereof (including any extension, continuation or termination described
therein).

                  (V) "Total Payments" shall mean those payments so described in

gross income of the Executive under Code Sections 125 or 401(k) and minus all
amounts includible in the gross income of the Executive for annual base salary,

                               SEVERANCE AGREEMENT

         THIS AGREEMENT, dated December 1, 1999, is made by and between PIEDMONT
NATURAL GAS COMPANY, INC., a North Carolina corporation (the "Company"), and RAY
B. KILLOUGH (the "Executive").

         WHEREAS, the Company considers it essential to the best interests of
its shareholders to foster the continued employment of key management personnel;
and

         WHEREAS, the Board of the Company recognizes that, as is the case with
many publicly held corporations, the possibility of a Change in Control exists
and that such possibility, and the uncertainty and questions which it may raise
among management, may result in the departure or distraction of management
personnel to the detriment of the Company and its shareholders; and

         WHEREAS, the Board has determined that appropriate steps should be
taken to reinforce and encourage the continued attention and dedication of
members of the Company's management, including the Executive, to their assigned
duties without distraction in the face of potentially disturbing circumstances
arising from the possibility of a Change in Control; and

         WHEREAS, contemporaneous with this Agreement, the Company and the
Executive have entered into an Employment Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the Company and the Executive hereby agree as
follows:

         1. Defined Terms. The definitions of capitalized terms used in this
Agreement are provided in the last Section hereof.

         2. Term of Agreement. The Term of this Agreement shall commence on the
date hereof and shall continue in effect through December 31, 2001; provided,
however, that commencing on January 1, 2002 and each January 1 thereafter, the
Term shall automatically be extended for one additional year unless, not later
than fifteen (15) months prior to the applicable January 1, the Company or the
Executive shall have given notice not to extend the Term; and further provided,
however, that if a Change in Control shall have occurred during the Term, the
Term shall expire at the end of the thirty-sixth (36th) calendar month after the
calendar month in which such Change in Control occurred. For example, if a
Change in Control were to occur on July 1, 1999, the Term of this Agreement
would expire on June 30, 2002, and if a Change in Control were to occur on July
1, 2002, the Term of this Agreement would expire on June 30, 2005 (regardless of
whether on or before September 30, 2001 either party had given notice to the
other party not to extend the Term as provided above).

         3. Company's Covenants Summarized. In order to induce the Executive to
remain in the employ of the Company and in consideration of the Executive's
covenants set forth in Section 4 hereof, the Company agrees, under the
conditions described herein, to pay the Executive the Severance Payments and the
other payments and benefits described herein. Except as provided in Section 9.1
hereof, no Severance Payments shall be payable under this Agreement unless there
shall have been (or, under the terms of the second sentence of Section 6.1
hereof, there shall be deemed to have been) a termination of the Executive's
employment with the Company following a Change in Control and during the Term.
This Agreement shall not be construed as creating an express or implied contract
of employment and, except as otherwise agreed in writing between the Executive
and the Company, the Executive shall not have any right to be retained in the
employ of the Company.

         4. The Executive's Covenants. The Executive agrees that, subject to the
terms and conditions of this Agreement, in the event of a Potential Change in
Control during the Term, the Executive will remain in the employ of the Company
until the earliest of (i) a date which is twelve (12) months from the date of
such Potential Change of Control, (ii) the date of a Change in Control, (iii)
the date of termination by the Executive of the Executive's employment for Good
Reason or by reason of death, Disability or Retirement, or (iv) the termination
by the Company of the Executive's employment for any reason. Should the
Executive fail to comply with the provisions of this paragraph 4, the Company's
sole remedy shall be to deny the payment of any Severance Payments to the
Executive.

         5. Compensation Other Than Severance Payments.

                  5.1 Following a Change in Control and during the Term, during
any period that the Executive fails to perform the Executive's full-time duties
with the Company as a result of incapacity due to physical or mental illness,
the Company shall pay the Executive's full salary to the Executive at the rate
in effect at the commencement of any such period, together with all compensation
and benefits payable to the Executive under the terms of any compensation,
benefit or incentive plan, program or arrangement maintained by the Company
during such period, until the Executive's employment is terminated by the
Company for Disability.

                  5.2 If the Executive's employment shall be terminated for any
reason following a Change in Control and during the Term, the Company shall pay
the Executive's full salary to the Executive through the Date of Termination at
the rate in effect immediately prior to the Date of Termination or, if higher,
the rate in effect immediately prior to the first occurrence of an event or
circumstance constituting Good Reason, together with all compensation and
benefits payable to the Executive through the Date of Termination under the
terms of the Company's executive compensation, benefit and incentive plans,
programs or arrangements as in effect immediately prior to the Date of
Termination or, if more favorable to the Executive, as in effect immediately
prior to the first occurrence of an event or circumstance constituting Good
Reason.


                                       2
<PAGE>   3

                  5.3 If the Executive's employment shall be terminated for any
reason following a Change in Control and during the Term, the Company shall pay
to the Executive the Executive's normal post-termination compensation and
benefits as such payments become due, including in a lump sum in cash that
portion of the Executive's vacation pay vested and accrued but not paid. Such
post-termination compensation and benefits shall be determined under, and paid
in accordance with, the Company's long-term incentive stock plan, pension,
supplemental retirement, insurance and other executive compensation, benefit or
incentive plans, programs and arrangements as in effect immediately prior to the
Date of Termination or, if more favorable to the Executive, as in effect
immediately prior to the occurrence of the first event or circumstance
constituting Good Reason.

         6. Severance Payments.

                  6.1 Subject to Section 6.2 hereof, if the Executive's
employment is terminated following a Change in Control and during the Term,
other than (A) by the Company for Cause, (B) by reason of death or Disability,
or (C) by the Executive without Good Reason (including Retirement by the
Executive), then the Company shall pay the Executive the amounts, and provide
the Executive the benefits, described in this Section 6.1 ("Severance
Payments"), in addition to any payments and benefits to which the Executive is
entitled under Section 5 hereof. For purposes of this Agreement, the Executive's
employment shall be deemed to have been terminated following a Change in Control
by the Company without Cause or by the Executive with Good Reason, if (i) the
Executive's employment is terminated by the Company without Cause prior to a
Change in Control (whether or not a Change in Control ever occurs) and such
termination was at the request or direction of a Person who has entered into an
agreement with the Company the consummation of which would constitute a Change
in Control, (ii) the Executive terminates his employment for Good Reason prior
to a Change in Control (whether or not a Change in Control ever occurs) and the
circumstance or event which constitutes Good Reason occurs at the request or
direction of such Person, or (iii) the Executive's employment is terminated by
the Company without Cause or by the Executive for Good Reason and such
termination or the circumstance or event which constitutes Good Reason is
otherwise in connection with or in anticipation of a Change in Control (whether
or not a Change in Control ever occurs). For purposes of any determination
regarding the applicability of the immediately preceding sentence, any position
taken by the Executive shall be presumed to be correct unless the Company
establishes by clear and convincing evidence that such position is not correct.

                           (A) In lieu of any further salary payments to the
Executive for periods subsequent to the Date of Termination and in lieu of any
severance benefit otherwise payable to the Executive, the Company shall pay to
the Executive a lump sum severance payment, in cash, equal to 3.00 times the sum
of (i) the Executive's annual base salary as in effect immediately prior to the
Date of Termination or, if higher, in effect immediately prior to the first
occurrence of an event or circumstance constituting Good Reason and (ii) an
amount equal to the average of the Executive's annual W-2 Compensation for the
three years ending on the last day of the month prior to the Date of
Termination.


                                       3
<PAGE>   4

                           (B) For the 36-month period immediately following the
Date of Termination, the Company shall arrange to provide the Executive and his
dependents life, disability, accident and health insurance benefits
substantially similar to those provided to the Executive and his dependents
immediately prior to the Date of Termination or, if more favorable to the
Executive, those provided to the Executive and his dependents immediately prior
to the first occurrence of an event or circumstance constituting Good Reason, at
no greater cost to the Executive than the cost to the Executive immediately
prior to such date or occurrence; provided, however, that, unless the Executive
consents to a different method (after taking into account the effect of such
method on the calculation of "parachute payments" pursuant to Section 6.2
hereof), such health insurance benefits shall be provided through a third-party
insurer. Benefits otherwise receivable by the Executive pursuant to this Section
6.1(B) shall be reduced to the extent benefits of the same type are received by
or made available to the Executive during the 36-month period following the
Executive's termination of employment (and any such benefits received by or made
available to the Executive shall be reported to the Company by the Executive);
provided, however, that the Company shall reimburse the Executive for the
excess, if any, of the cost of such benefits to the Executive over such cost
immediately prior to the Date of Termination or, if more favorable to the
Executive, the first occurrence of an event or circumstance constituting Good
Reason. If the Severance Payments shall be decreased pursuant to Section 6.2
hereof, and the Section 6.1(B) benefits which remain payable after the
application of Section 6.2 hereof are thereafter reduced pursuant to the
immediately preceding sentence, the Company shall, no later than five (5)
business days following such reduction, pay to the Executive the least of (a)
the amount of the decrease made in the Severance Payments pursuant to Section
6.2 hereof, (b) the amount of the subsequent reduction in these Section 6.1(B)
benefits, or (c) the maximum amount which can be paid to the Executive without
being, or causing any other payment to be, nondeductible by reason of section
280G of the Code.

                  6.2 (A) Notwithstanding any other provisions of this
Agreement, in the event that any payment or benefit received or to be received
by the Executive in connection with a Change in Control or the termination of
the Executive's employment (whether pursuant to the terms of this Agreement or
any other plan, arrangement or agreement with the Company, any Person whose
actions result in a Change in Control or any Person affiliated with the Company
or such Person) (all such payments and benefits, including the Severance
Payments, being hereinafter called "Total Payments") would not be deductible (in
whole or part), by the Company, an affiliate or Person making such payment or
providing such benefit as a result of section 280G of the Code, then, to the
extent necessary to make such portion of the Total Payments deductible (and
after taking into account any reduction in the Total Payments provided by reason
of section 280G of the Code in such other plan, arrangement or agreement), the
cash Severance Payments shall first be reduced (if necessary, to zero), and all
other Severance Payments shall thereafter be reduced (if necessary, to zero);
provided, however, that the Executive may elect to have the noncash Severance
Payments reduced (or eliminated) prior to any reduction of the cash Severance
Payments.

                           (B) For purposes of this limitation, (i) no portion
of the Total Payments the receipt or enjoyment of which the Executive shall have
waived at such time and in such manner as not to constitute a "payment" within
the meaning of section 280G(b) of the Code shall be taken



                                       4
<PAGE>   5

into account, (ii) no portion of the Total Payments shall be taken into account
which, in the opinion of tax counsel ("Tax Counsel") reasonably acceptable to
the Executive and selected by the accounting firm which was, immediately prior
to the Change in Control, the Company's independent auditor (the "Auditor"),
does not constitute a "parachute payment" within the meaning of section
280G(b)(2) of the Code, including by reason of section 280G(b)(4)(A) of the
Code, (iii) the Severance Payments shall be reduced only to the extent necessary
so that the Total Payments (other than those referred to in clauses (i) or (ii))
in their entirety constitute reasonable compensation for services actually
rendered within the meaning of section 280G(b)(4)(B) of the Code or are
otherwise not subject to disallowance as deductions by reason of section 280G of
the Code, in the opinion of Tax Counsel, and (iv) the value of any noncash
benefit or any deferred payment or benefit included in the Total Payments shall
be determined by the Auditor in accordance with the principles of sections
280G(d)(3) and (4) of the Code.

                           (C) If it is established pursuant to a final
determination of a court or an Internal Revenue Service proceeding that,
notwithstanding the good faith of the Executive and the Company in applying the
terms of this Section 6.2, the Total Payments paid to or for the Executive's
benefit are in an amount that would result in any portion of such Total Payments
being subject to the Excise Tax, then, if such repayment would result in (i) no
portion of the remaining Total Payments being subject to the Excise Tax and (ii)
a dollar-for-dollar reduction in the Executive's taxable income and wages for
purposes of federal, state and local income and employment taxes, the Executive
shall have an obligation to pay the Company upon demand an amount equal to the
sum of (i) the excess of the Total Payments paid to or for the Executive's
benefit over the Total Payments that could have been paid to or for the
Executive's benefit without any portion of such Total Payments being subject to
the Excise Tax; and (ii) interest on the amount set forth in clause (i) of this
sentence at the rate provided in section 1274(b)(2)(B) of the Code from the date
of the Executive's receipt of such excess until the date of such payment.

                  6.3 The payments provided in subsection (A) of Section 6.1
hereof shall be made not later than the fifth day following the Date of
Termination; provided, however, that if the amounts of such payments, and the
limitation on such payments set forth in Section 6.2 hereof, cannot be finally
determined on or before such day, the Company shall pay to the Executive on such
day an estimate, as determined in good faith by the Company of the minimum
amount of such payments to which the Executive is clearly entitled and shall pay
the remainder of such payments (together with interest on the unpaid remainder
(or on all such payments to the extent the Company fails to make such payments
when due) at 120% of the rate provided in section 1274(b)(2)(B) of the Code) as
soon as the amount thereof can be determined but in no event later than the
thirtieth (30th) day after the Date of Termination. In the event that the amount
of the estimated payments exceeds the amount subsequently determined to have
been due, such excess shall constitute a loan by the Company to the Executive,
payable on the fifth (5th) business day after demand by the Company (together
with interest at 120% of the rate provided in section 1274(b)(2)(B) of the
Code). At the time that payments are made under this Agreement, the Company
shall provide the Executive with a written statement setting forth the manner in
which such payments were calculated and the basis for such calculations
including, without limitation, any opinions or other advice the Company has



                                       5
<PAGE>   6

received from Tax Counsel, the Auditor or other advisors or consultants (and any
such opinions or advice which are in writing shall be attached to the
statement).

         7. Termination Procedures and Compensation During Dispute.

                  7.1 Notice of Termination. After a Change in Control and
during the Term, any purported termination of the Executive's employment (other
than by reason of death) shall be communicated by written Notice of Termination
from one party hereto to the other party hereto in accordance with Section 10
hereof. For purposes of this Agreement, a "Notice of Termination" shall mean a
notice which shall indicate the specific termination provision in this Agreement
relied upon and shall set forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of the Executive's employment under
the provision so indicated. Further, a Notice of Termination for Cause is
required to include a copy of a resolution duly adopted by the affirmative vote
of not less than three-quarters (3/4) of the entire membership of the Board at a
meeting of the Board which was called and held for the purpose of considering
such termination (after reasonable notice to the Executive and an opportunity
for the Executive, together with the Executive's counsel, to be heard before the
Board) finding that, in the good faith opinion of the Board, the Executive was
guilty of conduct set forth in clause (i) or (ii) of the definition of Cause
herein, and specifying the particulars thereof in detail.

                  7.2 Date of Termination. "Date of Termination," with respect
to any purported termination of the Executive's employment after a Change in
Control and during the Term, shall mean (i) if the Executive's employment is
terminated for Disability, thirty (30) days after Notice of Termination is given
(provided that the Executive shall not have returned to the full-time
performance of the Executive's duties during such thirty (30) day period), and
(ii) if the Executive's employment is terminated for any other reason, the date
specified in the Notice of Termination (which, in the case of a termination by
the Company, shall not be less than thirty (30) days (except in the case of a
termination for Cause) and, in the case of a termination by the Executive, shall
not be less than fifteen (15) days nor more than sixty (60) days, respectively,
from the date such Notice of Termination is given).

                  7.3 Dispute Concerning Termination. If within fifteen (15)
days after any Notice of Termination is given, or, if later, prior to the Date
of Termination (as determined without regard to this Section 7.3), the party
receiving such Notice of Termination notifies the other party that a dispute
exists concerning the termination, the Date of Termination shall be extended
until the earlier of (i) the date on which the Term ends or (ii) the date on
which the dispute is finally resolved, either by mutual written agreement of the
parties or by a final judgment, order or decree of an arbitrator or a court of
competent jurisdiction (which is not appealable or with respect to which the
time for appeal therefrom has expired and no appeal has been perfected);
provided, however, that the Date of Termination shall be extended by a notice of
dispute given by the Executive only if such notice is given in good faith and
the Executive pursues the resolution of such dispute with reasonable diligence.


                                       6
<PAGE>   7

                  7.4 Compensation During Dispute. If a purported termination
occurs following a Change in Control and during the Term and the Date of
Termination is extended in accordance with Section 7.3 hereof, the Company shall
continue to pay the Executive the full compensation in effect when the notice
giving rise to the dispute was given (including, but not limited to, salary) and
continue the Executive as a participant in all compensation, benefit and
insurance plans in which the Executive was participating when the notice giving
rise to the dispute was given, until the Date of Termination, as determined in
accordance with Section 7.3 hereof. Amounts paid under this Section 7.4 are in
addition to all other amounts due under this Agreement (other than those due
under Section 5.2 hereof) and shall not be offset against or reduce any other
amounts due under this Agreement.

         8. No Mitigation. The Company agrees that, if the Executive's
employment with the Company terminates during the Term, the Executive is not
required to seek other employment or to attempt in any way to reduce any amounts
payable to the Executive by the Company pursuant to Section 6 hereof or Section
7.4 hereof. Further, the amount of any payment or benefit provided for in this
Agreement (other than Section 6.1(B) hereof) shall not be reduced by any
compensation earned by the Executive as the result of employment by another
employer, by retirement benefits, by offset against any amount claimed to be
owed by the Executive to the Company, or otherwise.

         9. Successors; Binding Agreement.

                  9.1 In addition to any obligations imposed by law upon any
successor to the Company, the Company will require any successor (whether direct
or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to expressly
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place. Failure of the Company to obtain such assumption and agreement
prior to the effectiveness of any such succession shall be a breach of this
Agreement and shall entitle the Executive to compensation from the Company in
the same amount and on the same terms as the Executive would be entitled to
hereunder if the Executive were to terminate the Executive's employment for Good
Reason after a Change in Control, except that, for purposes of implementing the
foregoing, the date on which any such succession becomes effective shall be
deemed the Date of Termination.

                  9.2 This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Executive shall die while any amount would still be payable to the Executive
hereunder (other than amounts which, by their terms, terminate upon the death of
the Executive) if the Executive had continued to live, all such amounts, unless
otherwise provided herein, shall be paid in accordance with the terms of this
Agreement to the executors, personal representatives or administrators of the
Executive's estate.

         10. Notices. For the purpose of this Agreement, notices and all other
communications provided for in the Agreement shall be in writing and shall be
deemed to have been duly given when



                                       7
<PAGE>   8

delivered or mailed by United States registered mail, return receipt requested,
postage prepaid, addressed, if to the Executive, to the address inserted below
the Executive's signature on the final page hereof and, if to the Company, to
the address set forth below, or to such other address as either party may have
furnished to the other in writing in accordance herewith, except that notice of
change of address shall be effective only upon actual receipt:

                           To the Company:

                           Piedmont Natural Gas Company, Inc.
                           P.O. Box 33068
                           Charlotte, North Carolina 28233

                           Attention: Corporate Secretary

         11. Miscellaneous. No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing and signed by the Executive and such officer as may be specifically
designated by the Board. No waiver by either party hereto at any time of any
breach by the other party hereto of, or of any lack of compliance with, any
condition or provision of this Agreement to be performed by such other party
shall be deemed a waiver of similar or dissimilar provisions or conditions at
the same or at any prior or subsequent time. This Agreement supersedes any other
agreements or representations, oral or otherwise, express or implied, with
respect to the subject matter hereof which have been made by either party;
provided, however, that this Agreement shall supersede any agreement setting
forth the terms and conditions of the Executive's employment with the Company
only in the event that the Executive's employment with the Company is terminated
on or following a Change in Control (i) by the Company other than for Cause or
(ii) by the Executive for Good Reason. The validity, interpretation,
construction and performance of this Agreement shall be governed by the laws of
the State of North Carolina. All references to sections of the Exchange Act or
the Code shall be deemed also to refer to any successor provisions to such
sections. Any payments provided for hereunder shall be paid net of any
applicable withholding required under federal, state or local law and any
additional withholding to which the Executive has agreed. The obligations of the
Company and the Executive under this Agreement which by their nature may require
either partial or total performance after the expiration of the Term (including,
without limitation, those under Sections 6 and 7 hereof) shall survive such
expiration.

         12. Validity. The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, which shall remain in full force and effect.

         13. Counterparts. This Agreement may be executed in several
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

         14. Settlement of Disputes; Arbitration.


                                       8
<PAGE>   9

                  14.1 All claims by the Executive for benefits under this
Agreement shall be directed to and determined by the Board and shall be in
writing. Any denial by the Board of a claim for benefits under this Agreement
shall be delivered to the Executive in writing and shall set forth the specific
reasons for the denial and the specific provisions of this Agreement relied
upon. The Board shall afford a reasonable opportunity to the Executive for a
review of the decision denying a claim and shall further allow the Executive to
appeal to the Board a decision of the Board within sixty (60) days after
notification by the Board that the Executive's claim has been denied.

                  14.2 Any further dispute or controversy arising under or in
connection with this Agreement shall be settled exclusively by arbitration in
Charlotte, North Carolina in accordance with the rules of the American
Arbitration Association then in effect; provided, however, that the evidentiary
standards set forth in this Agreement shall apply. Judgment may be entered on
the arbitrator's award in any court having jurisdiction. Notwithstanding any
provision of this Agreement to the contrary, the Executive shall be entitled to
seek specific performance of the Executive's right to be paid until the Date of
Termination during the pendency of any dispute or controversy arising under or
in connection with this Agreement.

         15. Definitions. For purposes of this Agreement, the following terms
shall have the meanings indicated below:

                  (A) "Affiliate" shall have the meaning set forth in Rule 12b-2

promulgated under Section 12 of the Exchange Act.

                  (B) "Auditor" shall have the meaning set forth in Section 6.2
hereof.

                  (C) "Base Amount" shall have the meaning set forth in section
280G(b)(3) of the Code.

                  (D) "Beneficial Owner" shall have the meaning set forth in
Rule 13d-3 under the Exchange Act.

                  (E) "Board" shall mean the Board of Directors of the Company.

                  (F) "Cause" for termination by the Company of the Executive's
employment shall mean (i) the willful and continued failure by the Executive to
substantially perform the Executive's duties with the Company (other than any
such failure resulting from the Executive's incapacity due to physical or mental
illness or any such actual or anticipated failure after the issuance of a Notice
of Termination for Good Reason by the Executive pursuant to Section 7.1 hereof)
which failure shall continue unabated for thirty (30) days after a written
demand for substantial performance is delivered to the Executive by the Board,
which demand specifically identifies the manner in which the Board believes that
the Executive has not substantially performed the Executive's duties, or (ii)
the willful engaging by the Executive in conduct which is demonstrably



                                       9
<PAGE>   10

and materially injurious to the Company or its subsidiaries, monetarily or
otherwise. For purposes of clauses (i) and (ii) of this definition, (x) no act,
or failure to act, on the Executive's part shall be deemed "willful" unless
done, or omitted to be done, by the Executive not in good faith and without
reasonable belief that the Executive's act, or failure to act, was in the best
interest of the Company and (y) in the event of a dispute concerning the
application of this provision, no claim by the Company that Cause exists shall
be given effect unless the Company establishes by clear and convincing evidence
that Cause exists.

                  (G) A "Change in Control" shall be deemed to have occurred if
the event set forth in any one of the following paragraphs shall have occurred:

                           (I) any Person is or becomes the Beneficial Owner,
directly or indirectly, of securities of the Company (not including in the
securities beneficially owned by such Person any securities acquired directly
from the Company or its affiliates) representing 20% or more of the combined
voting power of the Company's then outstanding securities, excluding any Person
who becomes such a Beneficial Owner in connection with a transaction described
in clause (i) of paragraph (III) below; or

                           (II) the following individuals cease for any reason
to constitute a majority of the number of directors then serving: individuals
who, on the date hereof, constitute the Board and any new director (other than a
director whose initial assumption of office is in connection with an actual or
threatened election contest, including but not limited to a consent
solicitation, relating to the election of directors of the Company) whose
appointment or election by the Board or nomination for election by the Company's
shareholders was approved or recommended by a vote of at least two-thirds (2/3)
of the directors then still in office who either were directors on the date
hereof or whose appointment, election or nomination for election was previously
so approved or recommended; or

                           (III) there is consummated a merger or consolidation
of the Company or any direct or indirect subsidiary of the Company with any
other corporation, other than (i) a merger or consolidation which would result
in the voting securities of the Company outstanding immediately prior to such
merger or consolidation continuing to represent (either by remaining outstanding
or by being converted into voting securities of the surviving entity or any
parent thereof), in combination with the ownership of any trustee or other
fiduciary holding securities under an employee benefit plan of the Company or
any subsidiary of the Company, at least 50% of the combined voting power of the

physical or mental illness. The Executive's continued employment shall not
constitute consent to, or a waiver of rights with respect to, any act or failure
to act constituting Good Reason hereunder.

                  For purposes of any determination regarding the existence of

salaried employees.

                  (S) "Severance Payments" shall have the meaning set forth in

                               SEVERANCE AGREEMENT

         THIS AGREEMENT, dated December 1, 1999, is made by and between PIEDMONT
NATURAL GAS COMPANY, INC., a North Carolina corporation (the "Company"), and
WARE F. SCHIEFER (the "Executive").

         WHEREAS, the Company considers it essential to the best interests of
its shareholders to foster the continued employment of key management personnel;
and

         WHEREAS, the Board of the Company recognizes that, as is the case with
many publicly held corporations, the possibility of a Change in Control exists
and that such possibility, and the uncertainty and questions which it may raise
among management, may result in the departure or distraction of management
personnel to the detriment of the Company and its shareholders; and

         WHEREAS, the Board has determined that appropriate steps should be
taken to reinforce and encourage the continued attention and dedication of
members of the Company's management, including the Executive, to their assigned
duties without distraction in the face of potentially disturbing circumstances
arising from the possibility of a Change in Control; and

         WHEREAS, contemporaneous with this Agreement, the Company and the
Executive have entered into an Employment Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the Company and the Executive hereby agree as
follows:

         1. Defined Terms. The definitions of capitalized terms used in this
Agreement are provided in the last Section hereof.

         2. Term of Agreement. The Term of this Agreement shall commence on the
date hereof and shall continue in effect through December 31, 2001; provided,
however, that commencing on January 1, 2002 and each January 1 thereafter, the
Term shall automatically be extended for one additional year unless, not later
than fifteen (15) months prior to the applicable January 1, the Company or the
Executive shall have given notice not to extend the Term; and further provided,
however, that if a Change in Control shall have occurred during the Term, the
Term shall expire at the end of the thirty-sixth (36th) calendar month after the
calendar month in which such Change in Control occurred. For example, if a
Change in Control were to occur on July 1, 1999, the Term of this Agreement
would expire on June 30, 2002, and if a Change in Control were to occur on July
1, 2002, the Term of this Agreement would expire on June 30, 2005 (regardless of
whether on or before September 30, 2001 either party had given notice to the
other party not to extend the Term as provided above).

         3. Company's Covenants Summarized. In order to induce the Executive to
remain in the employ of the Company and in consideration of the Executive's
covenants set forth in Section


<PAGE>   2

4 hereof, the Company agrees, under the conditions described herein, to pay the
Executive the Severance Payments and the other payments and benefits described
herein. Except as provided in Section 9.1 hereof, no Severance Payments shall be
payable under this Agreement unless there shall have been (or, under the terms
of the second sentence of Section 6.1 hereof, there shall be deemed to have
been) a termination of the Executive's employment with the Company following a
Change in Control and during the Term. This Agreement shall not be construed as
creating an express or implied contract of employment and, except as otherwise
agreed in writing between the Executive and the Company, the Executive shall not
have any right to be retained in the employ of the Company.

         4. The Executive's Covenants. The Executive agrees that, subject to the
terms and conditions of this Agreement, in the event of a Potential Change in
Control during the Term, the Executive will remain in the employ of the Company
until the earliest of (i) a date which is twelve (12) months from the date of
such Potential Change of Control, (ii) the date of a Change in Control, (iii)
the date of termination by the Executive of the Executive's employment for Good
Reason or by reason of death, Disability or Retirement, or (iv) the termination
by the Company of the Executive's employment for any reason. Should the
Executive fail to comply with the provisions of this paragraph 4, the Company's
sole remedy shall be to deny the payment of any Severance Payments to the
Executive.

         5. Compensation Other Than Severance Payments.

                  5.1 Following a Change in Control and during the Term, during
any period that the Executive fails to perform the Executive's full-time duties
with the Company as a result of incapacity due to physical or mental illness,
the Company shall pay the Executive's full salary to the Executive at the rate
in effect at the commencement of any such period, together with all compensation
and benefits payable to the Executive under the terms of any compensation,
benefit or incentive plan, program or arrangement maintained by the Company
during such period, until the Executive's employment is terminated by the
Company for Disability.

                  5.2 If the Executive's employment shall be terminated for any
reason following a Change in Control and during the Term, the Company shall pay
the Executive's full salary to the Executive through the Date of Termination at
the rate in effect immediately prior to the Date of Termination or, if higher,
the rate in effect immediately prior to the first occurrence of an event or
circumstance constituting Good Reason, together with all compensation and
benefits payable to the Executive through the Date of Termination under the
terms of the Company's executive compensation, benefit and incentive plans,
programs or arrangements as in effect immediately prior to the Date of
Termination or, if more favorable to the Executive, as in effect immediately
prior to the first occurrence of an event or circumstance constituting Good
Reason.

                  5.3 If the Executive's employment shall be terminated for any
reason following a Change in Control and during the Term, the Company shall pay
to the Executive the Executive's normal post-termination compensation and
benefits as such payments become due, including in a



                                       2
<PAGE>   3

lump sum in cash that portion of the Executive's vacation pay vested and accrued
but not paid. Such post-termination compensation and benefits shall be
determined under, and paid in accordance with, the Company's long-term incentive
stock plan, pension, supplemental retirement, insurance and other executive
compensation, benefit or incentive plans, programs and arrangements as in effect
immediately prior to the Date of Termination or, if more favorable to the
Executive, as in effect immediately prior to the occurrence of the first event
or circumstance constituting Good Reason.

         6. Severance Payments.

                  6.1 Subject to Section 6.2 hereof, if the Executive's
employment is terminated following a Change in Control and during the Term,
other than (A) by the Company for Cause, (B) by reason of death or Disability,
or (C) by the Executive without Good Reason (including Retirement by the
Executive), then the Company shall pay the Executive the amounts, and provide
the Executive the benefits, described in this Section 6.1 ("Severance
Payments"), in addition to any payments and benefits to which the Executive is
entitled under Section 5 hereof. For purposes of this Agreement, the Executive's
employment shall be deemed to have been terminated following a Change in Control
by the Company without Cause or by the Executive with Good Reason, if (i) the
Executive's employment is terminated by the Company without Cause prior to a
Change in Control (whether or not a Change in Control ever occurs) and such
termination was at the request or direction of a Person who has entered into an
agreement with the Company the consummation of which would constitute a Change
in Control, (ii) the Executive terminates his employment for Good Reason prior
to a Change in Control (whether or not a Change in Control ever occurs) and the
circumstance or event which constitutes Good Reason occurs at the request or
direction of such Person, or (iii) the Executive's employment is terminated by
the Company without Cause or by the Executive for Good Reason and such
termination or the circumstance or event which constitutes Good Reason is
otherwise in connection with or in anticipation of a Change in Control (whether
or not a Change in Control ever occurs). For purposes of any determination
regarding the applicability of the immediately preceding sentence, any position
taken by the Executive shall be presumed to be correct unless the Company
establishes by clear and convincing evidence that such position is not correct.

                           (A) In lieu of any further salary payments to the
Executive for periods subsequent to the Date of Termination and in lieu of any
severance benefit otherwise payable to the Executive, the Company shall pay to
the Executive a lump sum severance payment, in cash, equal to 3.00 times the sum
of (i) the Executive's annual base salary as in effect immediately prior to the
Date of Termination or, if higher, in effect immediately prior to the first
occurrence of an event or circumstance constituting Good Reason and (ii) an
amount equal to the average of the Executive's annual W-2 Compensation for the
three years ending on the last day of the month prior to the Date of
Termination.

                           (B) For the 36-month period immediately following the
Date of Termination, the Company shall arrange to provide the Executive and his
dependents life, disability, accident and health insurance benefits
substantially similar to those provided to the Executive and his dependents
immediately prior to the Date of Termination or, if more favorable to the
Executive,



                                       3
<PAGE>   4

those provided to the Executive and his dependents immediately prior to the
first occurrence of an event or circumstance constituting Good Reason, at no
greater cost to the Executive than the cost to the Executive immediately prior
to such date or occurrence; provided, however, that, unless the Executive
consents to a different method (after taking into account the effect of such
method on the calculation of "parachute payments" pursuant to Section 6.2
hereof), such health insurance benefits shall be provided through a third-party
insurer. Benefits otherwise receivable by the Executive pursuant to this Section
6.1(B) shall be reduced to the extent benefits of the same type are received by
or made available to the Executive during the 36-month period following the
Executive's termination of employment (and any such benefits received by or made
available to the Executive shall be reported to the Company by the Executive);
provided, however, that the Company shall reimburse the Executive for the
excess, if any, of the cost of such benefits to the Executive over such cost
immediately prior to the Date of Termination or, if more favorable to the
Executive, the first occurrence of an event or circumstance constituting Good
Reason. If the Severance Payments shall be decreased pursuant to Section 6.2
hereof, and the Section 6.1(B) benefits which remain payable after the
application of Section 6.2 hereof are thereafter reduced pursuant to the
immediately preceding sentence, the Company shall, no later than five (5)
business days following such reduction, pay to the Executive the least of (a)
the amount of the decrease made in the Severance Payments pursuant to Section
6.2 hereof, (b) the amount of the subsequent reduction in these Section 6.1(B)
benefits, or (c) the maximum amount which can be paid to the Executive without
being, or causing any other payment to be, nondeductible by reason of section
280G of the Code.

                  6.2 (A) Notwithstanding any other provisions of this
Agreement, in the event that any payment or benefit received or to be received
by the Executive in connection with a Change in Control or the termination of
the Executive's employment (whether pursuant to the terms of this Agreement or
any other plan, arrangement or agreement with the Company, any Person whose
actions result in a Change in Control or any Person affiliated with the Company
or such Person) (all such payments and benefits, including the Severance
Payments, being hereinafter called "Total Payments") would not be deductible (in
whole or part), by the Company, an affiliate or Person making such payment or
providing such benefit as a result of section 280G of the Code, then, to the
extent necessary to make such portion of the Total Payments deductible (and
after taking into account any reduction in the Total Payments provided by reason
of section 280G of the Code in such other plan, arrangement or agreement), the
cash Severance Payments shall first be reduced (if necessary, to zero), and all
other Severance Payments shall thereafter be reduced (if necessary, to zero);
provided, however, that the Executive may elect to have the noncash Severance
Payments reduced (or eliminated) prior to any reduction of the cash Severance
Payments.

                           (B) For purposes of this limitation, (i) no portion
of the Total Payments the receipt or enjoyment of which the Executive shall have
waived at such time and in such manner as not to constitute a "payment" within
the meaning of section 280G(b) of the Code shall be taken into account, (ii) no
portion of the Total Payments shall be taken into account which, in the opinion
of tax counsel ("Tax Counsel") reasonably acceptable to the Executive and
selected by the accounting firm which was, immediately prior to the Change in
Control, the Company's independent auditor (the "Auditor"), does not constitute
a "parachute payment" within the meaning of section



                                       4
<PAGE>   5

280G(b)(2) of the Code, including by reason of section 280G(b)(4)(A) of the
Code, (iii) the Severance Payments shall be reduced only to the extent necessary
so that the Total Payments (other than those referred to in clauses (i) or (ii))
in their entirety constitute reasonable compensation for services actually
rendered within the meaning of section 280G(b)(4)(B) of the Code or are
otherwise not subject to disallowance as deductions by reason of section 280G of
the Code, in the opinion of Tax Counsel, and (iv) the value of any noncash
benefit or any deferred payment or benefit included in the Total Payments shall
be determined by the Auditor in accordance with the principles of sections
280G(d)(3) and (4) of the Code.

                           (C) If it is established pursuant to a final
determination of a court or an Internal Revenue Service proceeding that,
notwithstanding the good faith of the Executive and the Company in applying the
terms of this Section 6.2, the Total Payments paid to or for the Executive's
benefit are in an amount that would result in any portion of such Total Payments
being subject to the Excise Tax, then, if such repayment would result in (i) no
portion of the remaining Total Payments being subject to the Excise Tax and (ii)
a dollar-for-dollar reduction in the Executive's taxable income and wages for
purposes of federal, state and local income and employment taxes, the Executive
shall have an obligation to pay the Company upon demand an amount equal to the
sum of (i) the excess of the Total Payments paid to or for the Executive's
benefit over the Total Payments that could have been paid to or for the
Executive's benefit without any portion of such Total Payments being subject to
the Excise Tax; and (ii) interest on the amount set forth in clause (i) of this
sentence at the rate provided in section 1274(b)(2)(B) of the Code from the date
of the Executive's receipt of such excess until the date of such payment.

                  6.3 The payments provided in subsection (A) of Section 6.1
hereof shall be made not later than the fifth day following the Date of
Termination; provided, however, that if the amounts of such payments, and the
limitation on such payments set forth in Section 6.2 hereof, cannot be finally
determined on or before such day, the Company shall pay to the Executive on such
day an estimate, as determined in good faith by the Company of the minimum
amount of such payments to which the Executive is clearly entitled and shall pay
the remainder of such payments (together with interest on the unpaid remainder
(or on all such payments to the extent the Company fails to make such payments
when due) at 120% of the rate provided in section 1274(b)(2)(B) of the Code) as
soon as the amount thereof can be determined but in no event later than the
thirtieth (30th) day after the Date of Termination. In the event that the amount
of the estimated payments exceeds the amount subsequently determined to have
been due, such excess shall constitute a loan by the Company to the Executive,
payable on the fifth (5th) business day after demand by the Company (together
with interest at 120% of the rate provided in section 1274(b)(2)(B) of the
Code). At the time that payments are made under this Agreement, the Company
shall provide the Executive with a written statement setting forth the manner in
which such payments were calculated and the basis for such calculations
including, without limitation, any opinions or other advice the Company has
received from Tax Counsel, the Auditor or other advisors or consultants (and any
such opinions or advice which are in writing shall be attached to the
statement).

         7. Termination Procedures and Compensation During Dispute.

                  7.1 Notice of Termination. After a Change in Control and
during the Term, any purported termination of the Executive's employment (other
than by reason of death) shall be communicated by written Notice of Termination
from one party hereto to the other party hereto in accordance with Section 10
hereof. For purposes of this Agreement, a "Notice of Termination" shall mean a
notice which shall indicate the specific termination provision in this Agreement
relied upon and shall set forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of the Executive's employment under
the provision so indicated. Further, a Notice of Termination for Cause is
required to include a copy of a resolution duly adopted by the affirmative vote
of not less than three-quarters (3/4) of the entire membership of the Board at a
meeting of the Board which was called and held for the purpose of considering
such termination (after reasonable notice to the Executive and an opportunity
for the Executive, together with the Executive's counsel, to be heard before the
Board) finding that, in the good faith opinion of the Board, the Executive was
guilty of conduct set forth in clause (i) or (ii) of the definition of Cause
herein, and specifying the particulars thereof in detail.

                  7.2 Date of Termination. "Date of Termination," with respect
to any purported termination of the Executive's employment after a Change in
Control and during the Term, shall mean (i) if the Executive's employment is
terminated for Disability, thirty (30) days after Notice of Termination is given
(provided that the Executive shall not have returned to the full-time
performance of the Executive's duties during such thirty (30) day period), and
(ii) if the Executive's employment is terminated for any other reason, the date
specified in the Notice of Termination (which, in the case of a termination by
the Company, shall not be less than thirty (30) days (except in the case of a
termination for Cause) and, in the case of a termination by the Executive, shall
not be less than fifteen (15) days nor more than sixty (60) days, respectively,
from the date such Notice of Termination is given).

                  7.3 Dispute Concerning Termination. If within fifteen (15)
days after any Notice of Termination is given, or, if later, prior to the Date
of Termination (as determined without regard to this Section 7.3), the party
receiving such Notice of Termination notifies the other party that a dispute
exists concerning the termination, the Date of Termination shall be extended
until the earlier of (i) the date on which the Term ends or (ii) the date on
which the dispute is finally resolved, either by mutual written agreement of the
parties or by a final judgment, order or decree of an arbitrator or a court of
competent jurisdiction (which is not appealable or with respect to which the
time for appeal therefrom has expired and no appeal has been perfected);
provided, however, that the Date of Termination shall be extended by a notice of
dispute given by the Executive only if such notice is given in good faith and
the Executive pursues the resolution of such dispute with reasonable diligence.

                  7.4 Compensation During Dispute. If a purported termination
occurs following a Change in Control and during the Term and the Date of
Termination is extended in accordance with Section 7.3 hereof, the Company shall
continue to pay the Executive the full compensation in



                                       6
<PAGE>   7

effect when the notice giving rise to the dispute was given (including, but not
limited to, salary) and continue the Executive as a participant in all
compensation, benefit and insurance plans in which the Executive was
participating when the notice giving rise to the dispute was given, until the
Date of Termination, as determined in accordance with Section 7.3 hereof.
Amounts paid under this Section 7.4 are in addition to all other amounts due
under this Agreement (other than those due under Section 5.2 hereof) and shall
not be offset against or reduce any other amounts due under this Agreement.

         8. No Mitigation. The Company agrees that, if the Executive's
employment with the Company terminates during the Term, the Executive is not
required to seek other employment or to attempt in any way to reduce any amounts
payable to the Executive by the Company pursuant to Section 6 hereof or Section
7.4 hereof. Further, the amount of any payment or benefit provided for in this
Agreement (other than Section 6.1(B) hereof) shall not be reduced by any
compensation earned by the Executive as the result of employment by another
employer, by retirement benefits, by offset against any amount claimed to be
owed by the Executive to the Company, or otherwise.

         9. Successors; Binding Agreement.

                  9.1 In addition to any obligations imposed by law upon any
successor to the Company, the Company will require any successor (whether direct
or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to expressly
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place. Failure of the Company to obtain such assumption and agreement
prior to the effectiveness of any such succession shall be a breach of this
Agreement and shall entitle the Executive to compensation from the Company in
the same amount and on the same terms as the Executive would be entitled to
hereunder if the Executive were to terminate the Executive's employment for Good
Reason after a Change in Control, except that, for purposes of implementing the
foregoing, the date on which any such succession becomes effective shall be
deemed the Date of Termination.

                  9.2 This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Executive shall die while any amount would still be payable to the Executive
hereunder (other than amounts which, by their terms, terminate upon the death of
the Executive) if the Executive had continued to live, all such amounts, unless
otherwise provided herein, shall be paid in accordance with the terms of this
Agreement to the executors, personal representatives or administrators of the
Executive's estate.

         10. Notices. For the purpose of this Agreement, notices and all other
communications provided for in the Agreement shall be in writing and shall be
deemed to have been duly given when delivered or mailed by United States
registered mail, return receipt requested, postage prepaid, addressed, if to the
Executive, to the address inserted below the Executive's signature on the final
page hereof and, if to the Company, to the address set forth below, or to such
other address as either



                                       7

party may have furnished to the other in writing in accordance herewith, except
that notice of change of address shall be effective only upon actual receipt:

                          To the Company:

                          Piedmont Natural Gas Company, Inc.
                          P.O. Box 33068
                          Charlotte, North Carolina 28233

                          Attention: Corporate Secretary

         11. Miscellaneous. No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing and signed by the Executive and such officer as may be specifically
designated by the Board. No waiver by either party hereto at any time of any
breach by the other party hereto of, or of any lack of compliance with, any
condition or provision of this Agreement to be performed by such other party
shall be deemed a waiver of similar or dissimilar provisions or conditions at
the same or at any prior or subsequent time. This Agreement supersedes any other
agreements or representations, oral or otherwise, express or implied, with
respect to the subject matter hereof which have been made by either party;
provided, however, that this Agreement shall supersede any agreement setting
forth the terms and conditions of the Executive's employment with the Company
only in the event that the Executive's employment with the Company is terminated
on or following a Change in Control (i) by the Company other than for Cause or
(ii) by the Executive for Good Reason. The validity, interpretation,
construction and performance of this Agreement shall be governed by the laws of
the State of North Carolina. All references to sections of the Exchange Act or
the Code shall be deemed also to refer to any successor provisions to such
sections. Any payments provided for hereunder shall be paid net of any
applicable withholding required under federal, state or local law and any
additional withholding to which the Executive has agreed. The obligations of the
Company and the Executive under this Agreement which by their nature may require
either partial or total performance after the expiration of the Term (including,
without limitation, those under Sections 6 and 7 hereof) shall survive such
expiration.

         12. Validity. The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, which shall remain in full force and effect.

         13. Counterparts. This Agreement may be executed in several
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

         14. Settlement of Disputes; Arbitration.

                  14.1 All claims by the Executive for benefits under this
Agreement shall be directed to and determined by the Board and shall be in
writing. Any denial by the Board of a claim



                                       8
<PAGE>   9

for benefits under this Agreement shall be delivered to the Executive in writing
and shall set forth the specific reasons for the denial and the specific
provisions of this Agreement relied upon. The Board shall afford a reasonable
opportunity to the Executive for a review of the decision denying a claim and
shall further allow the Executive to appeal to the Board a decision of the Board
within sixty (60) days after notification by the Board that the Executive's
claim has been denied.

                  14.2 Any further dispute or controversy arising under or in
connection with this Agreement shall be settled exclusively by arbitration in
Charlotte, North Carolina in accordance with the rules of the American
Arbitration Association then in effect; provided, however, that the evidentiary
standards set forth in this Agreement shall apply. Judgment may be entered on
the arbitrator's award in any court having jurisdiction. Notwithstanding any
provision of this Agreement to the contrary, the Executive shall be entitled to
seek specific performance of the Executive's right to be paid until the Date of
Termination during the pendency of any dispute or controversy arising under or
in connection with this Agreement.

                  The Executive's right to terminate the Executive's employment
for Good Reason shall not be affected by the Executive's incapacity due to
physical or mental illness. The Executive's continued employment shall not
constitute consent to, or a waiver of rights with respect to, any act or failure
to act constituting Good Reason hereunder.

                  For purposes of any determination regarding the existence of
Good Reason, any claim by the Executive that Good Reason exists shall be

have occurred:

                           (I) the Company enters into an agreement, the
consummation of which would result in the occurrence of a Change in Control;

directly or indirectly, of securities of the Company representing 15% or more of
either the then outstanding shares of common stock of the Company or the

                               SEVERANCE AGREEMENT

         THIS AGREEMENT, dated December 1, 1999, is made by and between PIEDMONT
NATURAL GAS COMPANY, INC., a North Carolina corporation (the "Company"), and
THOMAS E. SKAINS (the "Executive").

         WHEREAS, the Company considers it essential to the best interests of
its shareholders to foster the continued employment of key management personnel;
and

         WHEREAS, the Board of the Company recognizes that, as is the case with
many publicly held corporations, the possibility of a Change in Control exists
and that such possibility, and the uncertainty and questions which it may raise
among management, may result in the departure or distraction of management
personnel to the detriment of the Company and its shareholders; and

         WHEREAS, the Board has determined that appropriate steps should be
taken to reinforce and encourage the continued attention and dedication of
members of the Company's management, including the Executive, to their assigned
duties without distraction in the face of potentially disturbing circumstances
arising from the possibility of a Change in Control; and

         WHEREAS, contemporaneous with this Agreement, the Company and the
Executive have entered into an Employment Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the Company and the Executive hereby agree as
follows:

         1. Defined Terms. The definitions of capitalized terms used in this
Agreement are provided in the last Section hereof.

         2. Term of Agreement. The Term of this Agreement shall commence on the
date hereof and shall continue in effect through December 31, 2001; provided,
however, that commencing on January 1, 2002 and each January 1 thereafter, the
Term shall automatically be extended for one additional year unless, not later
than fifteen (15) months prior to the applicable January 1, the Company or the
Executive shall have given notice not to extend the Term; and further provided,
however, that if a Change in Control shall have occurred during the Term, the
Term shall expire at the end of the thirty-sixth (36th) calendar month after the
calendar month in which such Change in Control occurred. For example, if a
Change in Control were to occur on July 1, 1999, the Term of this Agreement
would expire on June 30, 2002, and if a Change in Control were to occur on July
1, 2002, the Term of this Agreement would expire on June 30, 2005 (regardless of
whether on or before September 30, 2001 either party had given notice to the
other party not to extend the Term as provided above).

         3. Company's Covenants Summarized. In order to induce the Executive to
remain in the employ of the Company and in consideration of the Executive's
covenants set forth in Section


<PAGE>   2

4 hereof, the Company agrees, under the conditions described herein, to pay the
Executive the Severance Payments and the other payments and benefits described
herein. Except as provided in Section 9.1 hereof, no Severance Payments shall be
payable under this Agreement unless there shall have been (or, under the terms
of the second sentence of Section 6.1 hereof, there shall be deemed to have
been) a termination of the Executive's employment with the Company following a
Change in Control and during the Term. This Agreement shall not be construed as
creating an express or implied contract of employment and, except as otherwise
agreed in writing between the Executive and the Company, the Executive shall not
have any right to be retained in the employ of the Company.

         4. The Executive's Covenants. The Executive agrees that, subject to the
terms and conditions of this Agreement, in the event of a Potential Change in
Control during the Term, the Executive will remain in the employ of the Company
until the earliest of (i) a date which is twelve (12) months from the date of
such Potential Change of Control, (ii) the date of a Change in Control, (iii)
the date of termination by the Executive of the Executive's employment for Good
Reason or by reason of death, Disability or Retirement, or (iv) the termination
by the Company of the Executive's employment for any reason. Should the
Executive fail to comply with the provisions of this paragraph 4, the Company's
sole remedy shall be to deny the payment of any Severance Payments to the
Executive.

         5. Compensation Other Than Severance Payments.

                  5.1 Following a Change in Control and during the Term, during
any period that the Executive fails to perform the Executive's full-time duties
with the Company as a result of incapacity due to physical or mental illness,
the Company shall pay the Executive's full salary to the Executive at the rate
in effect at the commencement of any such period, together with all compensation
and benefits payable to the Executive under the terms of any compensation,
benefit or incentive plan, program or arrangement maintained by the Company
during such period, until the Executive's employment is terminated by the
Company for Disability.

                  5.2 If the Executive's employment shall be terminated for any
reason following a Change in Control and during the Term, the Company shall pay
the Executive's full salary to the Executive through the Date of Termination at
the rate in effect immediately prior to the Date of Termination or, if higher,
the rate in effect immediately prior to the first occurrence of an event or
circumstance constituting Good Reason, together with all compensation and
benefits payable to the Executive through the Date of Termination under the
terms of the Company's executive compensation, benefit and incentive plans,
programs or arrangements as in effect immediately prior to the Date of
Termination or, if more favorable to the Executive, as in effect immediately
prior to the first occurrence of an event or circumstance constituting Good
Reason.

                  5.3 If the Executive's employment shall be terminated for any
reason following a Change in Control and during the Term, the Company shall pay
to the Executive the Executive's normal post-termination compensation and
benefits as such payments become due, including in a



                                       2
<PAGE>   3

lump sum in cash that portion of the Executive's vacation pay vested and accrued
but not paid. Such post-termination compensation and benefits shall be
determined under, and paid in accordance with, the Company's long-term incentive
stock plan, pension, supplemental retirement, insurance and other executive
compensation, benefit or incentive plans, programs and arrangements as in effect
immediately prior to the Date of Termination or, if more favorable to the
Executive, as in effect immediately prior to the occurrence of the first event
or circumstance constituting Good Reason.

         6. Severance Payments.

                  6.1 Subject to Section 6.2 hereof, if the Executive's
employment is terminated following a Change in Control and during the Term,
other than (A) by the Company for Cause, (B) by reason of death or Disability,
or (C) by the Executive without Good Reason (including Retirement by the
Executive), then the Company shall pay the Executive the amounts, and provide
the Executive the benefits, described in this Section 6.1 ("Severance
Payments"), in addition to any payments and benefits to which the Executive is
entitled under Section 5 hereof. For purposes of this Agreement, the Executive's
employment shall be deemed to have been terminated following a Change in Control
by the Company without Cause or by the Executive with Good Reason, if (i) the
Executive's employment is terminated by the Company without Cause prior to a
Change in Control (whether or not a Change in Control ever occurs) and such
termination was at the request or direction of a Person who has entered into an
agreement with the Company the consummation of which would constitute a Change
in Control, (ii) the Executive terminates his employment for Good Reason prior
to a Change in Control (whether or not a Change in Control ever occurs) and the
circumstance or event which constitutes Good Reason occurs at the request or
direction of such Person, or (iii) the Executive's employment is terminated by
the Company without Cause or by the Executive for Good Reason and such
termination or the circumstance or event which constitutes Good Reason is
otherwise in connection with or in anticipation of a Change in Control (whether
or not a Change in Control ever occurs). For purposes of any determination
regarding the applicability of the immediately preceding sentence, any position
taken by the Executive shall be presumed to be correct unless the Company
establishes by clear and convincing evidence that such position is not correct.

                           (A) In lieu of any further salary payments to the
Executive for periods subsequent to the Date of Termination and in lieu of any
severance benefit otherwise payable to the Executive, the Company shall pay to
the Executive a lump sum severance payment, in cash, equal to 3.00 times the sum
of (i) the Executive's annual base salary as in effect immediately prior to the
Date of Termination or, if higher, in effect immediately prior to the first
occurrence of an event or circumstance constituting Good Reason and (ii) an
amount equal to the average of the Executive's annual W-2 Compensation for the
three years ending on the last day of the month prior to the Date of
Termination.

                           (B) For the 36-month period immediately following the
Date of Termination, the Company shall arrange to provide the Executive and his
dependents life, disability, accident and health insurance benefits
substantially similar to those provided to the Executive and his dependents
immediately prior to the Date of Termination or, if more favorable to the
Executive,



                                       3
<PAGE>   4

those provided to the Executive and his dependents immediately prior to the
first occurrence of an event or circumstance constituting Good Reason, at no
greater cost to the Executive than the cost to the Executive immediately prior
to such date or occurrence; provided, however, that, unless the Executive
consents to a different method (after taking into account the effect of such
method on the calculation of "parachute payments" pursuant to Section 6.2
hereof), such health insurance benefits shall be provided through a third-party
insurer. Benefits otherwise receivable by the Executive pursuant to this Section
6.1(B) shall be reduced to the extent benefits of the same type are received by
or made available to the Executive during the 36-month period following the
Executive's termination of employment (and any such benefits received by or made
available to the Executive shall be reported to the Company by the Executive);
provided, however, that the Company shall reimburse the Executive for the
excess, if any, of the cost of such benefits to the Executive over such cost
immediately prior to the Date of Termination or, if more favorable to the
Executive, the first occurrence of an event or circumstance constituting Good
Reason. If the Severance Payments shall be decreased pursuant to Section 6.2
hereof, and the Section 6.1(B) benefits which remain payable after the
application of Section 6.2 hereof are thereafter reduced pursuant to the
immediately preceding sentence, the Company shall, no later than five (5)
business days following such reduction, pay to the Executive the least of (a)
the amount of the decrease made in the Severance Payments pursuant to Section
6.2 hereof, (b) the amount of the subsequent reduction in these Section 6.1(B)
benefits, or (c) the maximum amount which can be paid to the Executive without
being, or causing any other payment to be, nondeductible by reason of section
280G of the Code.

                  6.2 (A) Notwithstanding any other provisions of this
Agreement, in the event that any payment or benefit received or to be received
by the Executive in connection with a Change in Control or the termination of
the Executive's employment (whether pursuant to the terms of this Agreement or
any other plan, arrangement or agreement with the Company, any Person whose
actions result in a Change in Control or any Person affiliated with the Company
or such Person) (all such payments and benefits, including the Severance
Payments, being hereinafter called "Total Payments") would not be deductible (in
whole or part), by the Company, an affiliate or Person making such payment or
providing such benefit as a result of section 280G of the Code, then, to the
extent necessary to make such portion of the Total Payments deductible (and
after taking into account any reduction in the Total Payments provided by reason
of section 280G of the Code in such other plan, arrangement or agreement), the
cash Severance Payments shall first be reduced (if necessary, to zero), and all
other Severance Payments shall thereafter be reduced (if necessary, to zero);
provided, however, that the Executive may elect to have the noncash Severance
Payments reduced (or eliminated) prior to any reduction of the cash Severance
Payments.

                           (B) For purposes of this limitation, (i) no portion
of the Total Payments the receipt or enjoyment of which the Executive shall have
waived at such time and in such manner as not to constitute a "payment" within
the meaning of section 280G(b) of the Code shall be taken into account, (ii) no
portion of the Total Payments shall be taken into account which, in the opinion
of tax counsel ("Tax Counsel") reasonably acceptable to the Executive and
selected by the accounting firm which was, immediately prior to the Change in
Control, the Company's independent auditor (the "Auditor"), does not constitute
a "parachute payment" within the meaning of section



                                       4
<PAGE>   5

280G(b)(2) of the Code, including by reason of section 280G(b)(4)(A) of the
Code, (iii) the Severance Payments shall be reduced only to the extent necessary
so that the Total Payments (other than those referred to in clauses (i) or (ii))
in their entirety constitute reasonable compensation for services actually
rendered within the meaning of section 280G(b)(4)(B) of the Code or are
otherwise not subject to disallowance as deductions by reason of section 280G of
the Code, in the opinion of Tax Counsel, and (iv) the value of any noncash
benefit or any deferred payment or benefit included in the Total Payments shall
be determined by the Auditor in accordance with the principles of sections
280G(d)(3) and (4) of the Code.

                           (C) If it is established pursuant to a final
determination of a court or an Internal Revenue Service proceeding that,
notwithstanding the good faith of the Executive and the Company in applying the
terms of this Section 6.2, the Total Payments paid to or for the Executive's
benefit are in an amount that would result in any portion of such Total Payments
being subject to the Excise Tax, then, if such repayment would result in (i) no
portion of the remaining Total Payments being subject to the Excise Tax and (ii)
a dollar-for-dollar reduction in the Executive's taxable income and wages for
purposes of federal, state and local income and employment taxes, the Executive
shall have an obligation to pay the Company upon demand an amount equal to the
sum of (i) the excess of the Total Payments paid to or for the Executive's
benefit over the Total Payments that could have been paid to or for the
Executive's benefit without any portion of such Total Payments being subject to
the Excise Tax; and (ii) interest on the amount set forth in clause (i) of this
sentence at the rate provided in section 1274(b)(2)(B) of the Code from the date
of the Executive's receipt of such excess until the date of such payment.

                  6.3 The payments provided in subsection (A) of Section 6.1
hereof shall be made not later than the fifth day following the Date of
Termination; provided, however, that if the amounts of such payments, and the
limitation on such payments set forth in Section 6.2 hereof, cannot be finally
determined on or before such day, the Company shall pay to the Executive on such
day an estimate, as determined in good faith by the Company of the minimum
amount of such payments to which the Executive is clearly entitled and shall pay
the remainder of such payments (together with interest on the unpaid remainder
(or on all such payments to the extent the Company fails to make such payments
when due) at 120% of the rate provided in section 1274(b)(2)(B) of the Code) as
soon as the amount thereof can be determined but in no event later than the
thirtieth (30th) day after the Date of Termination. In the event that the amount
of the estimated payments exceeds the amount subsequently determined to have
been due, such excess shall constitute a loan by the Company to the Executive,
payable on the fifth (5th) business day after demand by the Company (together
with interest at 120% of the rate provided in section 1274(b)(2)(B) of the
Code). At the time that payments are made under this Agreement, the Company
shall provide the Executive with a written statement setting forth the manner in
which such payments were calculated and the basis for such calculations
including, without limitation, any opinions or other advice the Company has
received from Tax Counsel, the Auditor or other advisors or consultants (and any
such opinions or advice which are in writing shall be attached to the
statement).

         7. Termination Procedures and Compensation During Dispute.

                  7.1 Notice of Termination. After a Change in Control and
during the Term, any purported termination of the Executive's employment (other
than by reason of death) shall be communicated by written Notice of Termination
from one party hereto to the other party hereto in accordance with Section 10
hereof. For purposes of this Agreement, a "Notice of Termination" shall mean a
notice which shall indicate the specific termination provision in this Agreement
relied upon and shall set forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of the Executive's employment under
the provision so indicated. Further, a Notice of Termination for Cause is
required to include a copy of a resolution duly adopted by the affirmative vote
of not less than three-quarters (3/4) of the entire membership of the Board at a
meeting of the Board which was called and held for the purpose of considering
such termination (after reasonable notice to the Executive and an opportunity
for the Executive, together with the Executive's counsel, to be heard before the
Board) finding that, in the good faith opinion of the Board, the Executive was
guilty of conduct set forth in clause (i) or (ii) of the definition of Cause
herein, and specifying the particulars thereof in detail.

                  7.2 Date of Termination. "Date of Termination," with respect
to any purported termination of the Executive's employment after a Change in
Control and during the Term, shall mean (i) if the Executive's employment is
terminated for Disability, thirty (30) days after Notice of Termination is given
(provided that the Executive shall not have returned to the full-time
performance of the Executive's duties during such thirty (30) day period), and
(ii) if the Executive's employment is terminated for any other reason, the date
specified in the Notice of Termination (which, in the case of a termination by
the Company, shall not be less than thirty (30) days (except in the case of a
termination for Cause) and, in the case of a termination by the Executive, shall
not be less than fifteen (15) days nor more than sixty (60) days, respectively,
from the date such Notice of Termination is given).

                  7.3 Dispute Concerning Termination. If within fifteen (15)
days after any Notice of Termination is given, or, if later, prior to the Date
of Termination (as determined without regard to this Section 7.3), the party
receiving such Notice of Termination notifies the other party that a dispute
exists concerning the termination, the Date of Termination shall be extended
until the earlier of (i) the date on which the Term ends or (ii) the date on
which the dispute is finally resolved, either by mutual written agreement of the
parties or by a final judgment, order or decree of an arbitrator or a court of
competent jurisdiction (which is not appealable or with respect to which the
time for appeal therefrom has expired and no appeal has been perfected);
provided, however, that the Date of Termination shall be extended by a notice of
dispute given by the Executive only if such notice is given in good faith and
the Executive pursues the resolution of such dispute with reasonable diligence.

                  7.4 Compensation During Dispute. If a purported termination
occurs following a Change in Control and during the Term and the Date of
Termination is extended in accordance with Section 7.3 hereof, the Company shall
continue to pay the Executive the full compensation in



                                       6
<PAGE>   7

effect when the notice giving rise to the dispute was given (including, but not
limited to, salary) and continue the Executive as a participant in all
compensation, benefit and insurance plans in which the Executive was
participating when the notice giving rise to the dispute was given, until the
Date of Termination, as determined in accordance with Section 7.3 hereof.
Amounts paid under this Section 7.4 are in addition to all other amounts due
under this Agreement (other than those due under Section 5.2 hereof) and shall
not be offset against or reduce any other amounts due under this Agreement.

         8. No Mitigation. The Company agrees that, if the Executive's
employment with the Company terminates during the Term, the Executive is not
required to seek other employment or to attempt in any way to reduce any amounts
payable to the Executive by the Company pursuant to Section 6 hereof or Section
7.4 hereof. Further, the amount of any payment or benefit provided for in this
Agreement (other than Section 6.1(B) hereof) shall not be reduced by any
compensation earned by the Executive as the result of employment by another
employer, by retirement benefits, by offset against any amount claimed to be
owed by the Executive to the Company, or otherwise.

         9. Successors; Binding Agreement.

                  9.1 In addition to any obligations imposed by law upon any
successor to the Company, the Company will require any successor (whether direct
or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to expressly
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place. Failure of the Company to obtain such assumption and agreement
prior to the effectiveness of any such succession shall be a breach of this
Agreement and shall entitle the Executive to compensation from the Company in
the same amount and on the same terms as the Executive would be entitled to
hereunder if the Executive were to terminate the Executive's employment for Good
Reason after a Change in Control, except that, for purposes of implementing the
foregoing, the date on which any such succession becomes effective shall be
deemed the Date of Termination.

                  9.2 This Agreement shall inure to the benefit of and be
enforceable by the Executive's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If the
Executive shall die while any amount would still be payable to the Executive
hereunder (other than amounts which, by their terms, terminate upon the death of
the Executive) if the Executive had continued to live, all such amounts, unless
otherwise provided herein, shall be paid in accordance with the terms of this
Agreement to the executors, personal representatives or administrators of the
Executive's estate.

         10. Notices. For the purpose of this Agreement, notices and all other
communications provided for in the Agreement shall be in writing and shall be
deemed to have been duly given when delivered or mailed by United States
registered mail, return receipt requested, postage prepaid, addressed, if to the
Executive, to the address inserted below the Executive's signature on the final
page hereof and, if to the Company, to the address set forth below, or to such
other address as either


                                       7
<PAGE>   8

party may have furnished to the other in writing in accordance herewith, except
that notice of change of address shall be effective only upon actual receipt:

                             To the Company:

                             Piedmont Natural Gas Company, Inc.
                             P.O. Box 33068
                             Charlotte, North Carolina 28233

                             Attention: Corporate Secretary

         11. Miscellaneous. No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing and signed by the Executive and such officer as may be specifically
designated by the Board. No waiver by either party hereto at any time of any
breach by the other party hereto of, or of any lack of compliance with, any
condition or provision of this Agreement to be performed by such other party
shall be deemed a waiver of similar or dissimilar provisions or conditions at
the same or at any prior or subsequent time. This Agreement supersedes any other
agreements or representations, oral or otherwise, express or implied, with
respect to the subject matter hereof which have been made by either party;
provided, however, that this Agreement shall supersede any agreement setting
forth the terms and conditions of the Executive's employment with the Company
only in the event that the Executive's employment with the Company is terminated
on or following a Change in Control (i) by the Company other than for Cause or
(ii) by the Executive for Good Reason. The validity, interpretation,
construction and performance of this Agreement shall be governed by the laws of
the State of North Carolina. All references to sections of the Exchange Act or
the Code shall be deemed also to refer to any successor provisions to such
sections. Any payments provided for hereunder shall be paid net of any
applicable withholding required under federal, state or local law and any
additional withholding to which the Executive has agreed. The obligations of the
Company and the Executive under this Agreement which by their nature may require
either partial or total performance after the expiration of the Term (including,
without limitation, those under Sections 6 and 7 hereof) shall survive such
expiration.

         12. Validity. The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, which shall remain in full force and effect.

         13. Counterparts. This Agreement may be executed in several
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

         14. Settlement of Disputes; Arbitration.

                  14.1 All claims by the Executive for benefits under this
Agreement shall be directed to and determined by the Board and shall be in
writing. Any denial by the Board of a claim



                                       8
<PAGE>   9

for benefits under this Agreement shall be delivered to the Executive in writing
and shall set forth the specific reasons for the denial and the specific
provisions of this Agreement relied upon. The Board shall afford a reasonable
opportunity to the Executive for a review of the decision denying a claim and
shall further allow the Executive to appeal to the Board a decision of the Board
within sixty (60) days after notification by the Board that the Executive's
claim has been denied.

                  14.2 Any further dispute or controversy arising under or in
connection with this Agreement shall be settled exclusively by arbitration in
Charlotte, North Carolina in accordance with the rules of the American
Arbitration Association then in effect; provided, however, that the evidentiary
standards set forth in this Agreement shall apply. Judgment may be entered on
the arbitrator's award in any court having jurisdiction. Notwithstanding any
provision of this Agreement to the contrary, the Executive shall be entitled to
seek specific performance of the Executive's right to be paid until the Date of
Termination during the pendency of any dispute or controversy arising under or
in connection with this Agreement.

         15. Definitions. For purposes of this Agreement, the following terms

such failure resulting from the Executive's incapacity due to physical or mental
illness or any such actual or anticipated failure after the issuance of a Notice
of Termination for Good Reason by the Executive pursuant to Section 7.1 hereof)
which failure shall continue unabated for thirty (30) days after a written
demand for substantial performance is delivered to the Executive by the Board,
which demand specifically identifies the manner in which the Board believes that
the Executive has not substantially performed the Executive's duties, or (ii)
the willful engaging by the Executive in conduct which is demonstrably and
materially injurious to the Company or its subsidiaries, monetarily or
otherwise. For purposes of clauses (i) and (ii) of this definition, (x) no act,

reasonable belief that the Executive's act, or failure to act, was in the best

in accordance with the Company's normal vacation policy in effect at the time of
the Change in Control; or

                           (VII) any purported termination of the Executive's
employment which is not effected pursuant to a Notice of Termination satisfying
the requirements of Section 7.1 hereof; for purposes of this Agreement, no such
purported termination shall be effective.

                  The Executive's right to terminate the Executive's employment
for Good Reason shall not be affected by the Executive's incapacity due to
physical or mental illness. The Executive's continued employment shall not
constitute consent to, or a waiver of rights with respect to, any act or failure
to act constituting Good Reason hereunder.

                  For purposes of any determination regarding the existence of
Good Reason, any claim by the Executive that Good Reason exists shall be

have occurred:

consummation of which would result in the occurrence of a Change in Control;

directly or indirectly, of securities of the Company representing 15% or more of
either the then outstanding shares of common stock of the Company or the

that, for purposes of this Agreement, a Potential Change in Control has
occurred.

                  (R) "Retirement" shall be deemed the reason for the
termination by the Executive of the Executive's employment if such employment is
terminated voluntarily by the Executive in accordance with the Company's
retirement policy, including early retirement, generally applicable to its
salaried employees.

                  (S) "Severance Payments" shall have the meaning set forth in

                                 LOAN AGREEMENT

This Loan Agreement (hereinafter called "Agreement") is effective June 30, 1999
and is between SouthStar Energy Services, LLC (hereinafter called "SouthStar"),
Georgia Natural Gas Company (hereinafter called "GNG"), Piedmont Energy Company
(hereinafter called "Piedmont") and Dynegy Hub Services Inc. (hereinafter called
"Dynegy").

WHEREAS, SouthStar, a joint venture of GNG, Piedmont and Dynegy, was formed for
the purpose of selling, on a non-regulated basis, energy commodities to retail
customers; and

WHEREAS, SouthStar wishes to establish lines of credit in the maximum aggregate
available principal amount of $75,000,000.00 which lines of credit contemplate
borrowing directly from GNG and Piedmont and Dynegy; and

WHEREAS, GNG, Piedmont and Dynegy wish to facilitate such credit arrangements on
the terms and conditions set forth herein.

NOW, THEREFORE FOR AND IN CONSIDERATION of the premises, the mutual covenants
contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto, intending to
be legally bound, hereby agree as follows:


<PAGE>   2

1.       GNG agrees to loan to SouthStar, from time to time upon the terms and
         conditions set forth herein, up to Thirty-Seven Million Five Hundred
         Thousand and no/100 Dollars (US$37,500,000.00). Piedmont agrees to loan
         to SouthStar, from time to time upon the terms and conditions set forth
         herein, up to Twenty-Two Million Five Hundred Thousand and no/100
         Dollars (US$22,500,000.00). Dynegy agrees to loan to SouthStar, from
         time to time upon the terms and conditions set forth herein, up to
         Fifteen Million and no/100 Dollars (US$15,000,000.00).

         Whenever SouthStar shall desire to borrow funds pursuant to this
         Agreement (each such borrowing being hereinafter referred to as a
         "Loan" and all such borrowings requested or outstanding at any given
         time being hereinafter referred to as "Loans"), SouthStar shall borrow
         50% of the requested Loan amount from GNG, 30% of the requested Loan
         amount from Piedmont and 20% of the requested Loan amount from Dynegy.

         Neither GNG, Piedmont nor Dynegy shall have any obligation to SouthStar
         whatsoever to make any Loan pursuant to this Agreement if at the time
         of the proposed funding thereof the aggregate principal amount of all
         Loans then outstanding exceeds, or upon the funding of such proposed
         Loan would exceed, $75,000,000.00. Similarly, (i) GNG shall have no
         obligation to SouthStar whatsoever to make any Loan pursuant to this
         Agreement if at the time of the proposed funding thereof the aggregate
         principal amount of all Loans then outstanding from GNG to SouthStar
         exceeds, or upon the funding of such proposed Loan would exceed,
         Thirty-Seven Million Five Hundred Thousand and no/100 Dollars
         (US$37,500,000.00), (ii) Piedmont, shall have no obligation to
         SouthStar


<PAGE>   3

         whatsoever to make any Loan pursuant to this Agreement if at the time
         of the proposed funding thereof the aggregate principal amount of all
         Loans then outstanding exceeds, or upon the funding of such proposed
         Loan would exceed, Twenty-Two Million Five Hundred Thousand and no/100
         Dollars (US$22,500,000.00), and (iii) Dynegy, shall have no obligation
         to SouthStar whatsoever to make any Loan pursuant to this Agreement if
         at the time of the proposed funding thereof the aggregate principal
         amount of all Loans then outstanding exceeds, or upon the funding of
         such proposed Loan would exceed, Fifteen Million and no/100 Dollars
         (US$15,000,000.00). In the event that any one of the parties, GNG,
         Piedmont or Dynegy, shall fail to fund all or part of their respective
         portions of a SouthStar requested Loan pursuant to a Loan request made
         by SouthStar under this Agreement, neither of the other parties shall
         have any obligation to make a loan pursuant to that SouthStar request.

         Any person listed in Appendix A is authorized to consummate Loans from
         GNG, Piedmont and Dynegy under this Agreement on behalf of SouthStar.
         Each of GNG, Piedmont and Dynegy shall designate in writing one contact
         person for all matters concerning Loans to SouthStar which designee may
         be changed by GNG, Piedmont or Dynegy, respectively, upon written
         notice to all parties to this Agreement.

2.       The Loans shall be made by GNG, Piedmont and Dynegy under this
         Agreement from time to time upon telephonic request from any person
         listed in Appendix A. At the time of each Loan, SouthStar will confirm
         the details of such Loan by transmitting a written notice to GNG,
         Piedmont and Dynegy, substantially in the form of Appendix B, detailing


<PAGE>   4

         the borrowing including: (i) the date of the notice; (ii) the requested
         date of the Loan; (iii) the aggregate principal amount of the Loan
         requested; (iv) the bank account to which Loan funds are to be
         disbursed; and (v) that the Loan is being requested pursuant to this
         Agreement. Further, such notice shall contain an affirmative
         representation and warranty that each of GNG, Piedmont and Dynegy are
         participating in the Loan pro rata based upon the following
         percentages: 50% for GNG; 30% for Piedmont; and 20% for Dynegy.

3.       Any and all payments (whether consisting of principal or interest) on
         an outstanding Loan shall be made by SouthStar to GNG, Piedmont and
         Dynegy pro rata based on the percentage of the Loan amount lent by
         each. In other words, assuming all Loans outstanding at the time of the
         payment were made by the Parties in percentages required in Paragraph 2
         above, GNG, Piedmont and Dynegy shall each receive the following
         percentage of any principal payment or interest payment by SouthStar:
         50% for GNG; 30% for Piedmont; and 20% for Dynegy. All payments by
         SouthStar to GNG, Piedmont and Dynegy shall be applied first to accrued
         interest, then to principal. All payments shall be applied to Loans in
         the order in which each Loan was made, such that payments are applied
         first to repayment of interest and principal on the Loan that has been
         outstanding for the longest period of time. The principal balance of
         Loans outstanding to GNG, Piedmont and Dynegy may be prepaid, in whole
         or in part, at any time without penalty (provided that prepayments are
         applied in the order described in the immediately preceding sentence).
         Principal amounts repaid to GNG, Piedmont and Dynegy may be re-borrowed
         by SouthStar, provided that the aggregate outstanding principal balance
         of all Loans does not at any time exceed Seventy-Five Million and
         no/100 Dollars


<PAGE>   5

         (US$75,000,000.00) and provided further that all other terms and
         conditions of this Agreement are complied with.

4.       Interest will accrue on the outstanding principal balance of each Loan
         made by GNG, Piedmont, and Dynegy at an annual fixed rate equal to
         LIBOR (hereinafter defined), plus eighty-five basis points. Interest
         shall be calculated based upon the actual number of days the principal
         amount in question has been outstanding and based upon a year
         consisting of 360 days.

         Payments of interest on the outstanding principal balance of Loans
         shall be due and payable, in arrears, quarterly on September 30, 1999,
         December 31, 1999, March 31, 2000, and June 27, 2000. If the due date
         for an interest payment is not a business day, then such payment shall
         be due on the next succeeding business day.

         Notwithstanding anything herein to the contrary, any Loan payments
         (whether principal or interest) not made as and when due shall bear
         interest from the date due until paid at a floating rate equal to the
         Prime Rate (hereinafter defined) plus 200 basis points. Such interest
         shall be calculated on the basis of a 360 day year for the actual
         number of days elapsed.

         For purposes of this Agreement, LIBOR shall mean the London Interbank
         Offered Rate for the Applicable Period (hereinafter defined) as
         published in the "Money Rates" column of the Eastern Edition of the
         Wall Street Journal on the effective date of the Loan

         in question, or if the Wall Street Journal is not published on such
         date, then as published in the Wall Street Journal on the next
         preceding business day.

         For purposes of this Agreement, "Applicable Period" shall mean: (i) one
         year for Loans with an effective date on or after June 30, 1999, but
         before December 28, 1999; (ii) six months for Loans with an effective
         date on or after December 28, 1999, but before March 28, 2000; (iii)
         three months for Loans with an effective date on or after March 28,
         2000, but before May 28, 2000; and (iv) one month for Loans with an
         effective date on or after May 28, 2000.

         For purposes of the Agreement, "Prime Rate" shall mean the "Prime Rate"
         as published in the "Money Rates" column of the Eastern Edition of the
         Wall Street Journal on the date in question, or if the Wall Street

                            INDEMNIFICATION AGREEMENT


         This Indemnification Agreement is made and entered into on this 15th
day of January 1999 by Piedmont Propane Company ("Indemnifying Party") in favor
of AGL Resources Inc. ("AGLR"). AGLR's affiliate, Atlanta Gas Light Services,
Inc., and the Indemnifying Party's affiliate, Piedmont Energy Company (the
"Affiliate"), are parties to that certain Limited Liability Company Agreement of
SouthStar Energy Services LLC dated July 1, 1998 ("LLC Agreement") as members of
SouthStar Energy Services LLC ("SouthStar"). Pursuant to that certain Guaranty
Agreement (the "Guaranty"), effective November 1, 1998, between AGLR and Atlanta
Gas Light Company, AGLR has agreed to guaranty SouthStar's obligations to
Atlanta Gas Light Company. AGLR's agreement with SouthStar to provide the
Guaranty to Atlanta Gas Light Company was subject to the condition that certain
affiliates of each member of SouthStar would indemnify AGLR against any losses
AGLR incurs as a result of AGLR providing financial support for SouthStar under
the Guaranty in accordance with the applicable SouthStar member's Allocable
Share of Net Profits and Losses, as set forth in the LLC Agreement. This
Indemnification Agreement sets forth the terms and conditions of that
indemnification.

         In consideration of the benefit the Indemnifying Party and its
affiliates derive from AGLR providing financial support to SouthStar pursuant to
the Guaranty and the benefit to AGLR of the Indemnifying Party indemnifying
AGLR, the parties agree as follows:

1.     The Indemnifying Party shall indemnify, defend and hold AGLR harmless
       against any losses, costs, fees, liabilities or other expenses AGLR
       incurs as a result of AGLR's providing financial support for SouthStar
       under the Guaranty ("Indemnified Expenses"). The Indemnifying Party shall
       be liable for indemnifying AGLR hereunder for an amount equal to the
       product of the Affiliate's Allocable Share (as set forth in the LLC
       Agreement or any successor agreement) and the Indemnified Expenses.
       Notwithstanding any statement herein to the contrary, the Indemnifying
       Party shall not be liable to AGLR to the extent that the Indemnified
       Expenses resulted from AGLR's gross negligence or willful misconduct.

2.     AGLR shall invoice the Indemnifying Party (at the address set forth in
       numbered paragraph 9 below) no later than ten days prior to the end of
       each calendar month for the Indemnifying Party's share of the Indemnified
       Expenses due from the previous calendar month or any portion thereof. The
       Indemnifying Party shall pay AGLR the amount of such invoice (via wire
       transfer to the account specified on the invoice) no later than the last
       day of


<PAGE>   2

       the calendar month during which AGLR sent the Indemnifying Party an
       invoice.


       If the Indemnifying Party fails to pay all of the amount of any invoice
       when that amount becomes due, the Indemnifying Party shall pay AGLR a
       late charge on the unpaid balance that shall accrue daily on each
       calendar day from the due date at an annual rate equal to two percentage
       points above the then-effective monthly prime commercial lending rate per
       annum announced by NationsBank, N.A. from time to time multiplied by the
       unpaid balance; provided, that for any period that such rate exceeds any
       applicable maximum rate permitted by law, the rate shall equal the
       applicable maximum rate.

3.     This Indemnification Agreement shall inure to the benefit of each party,
       its successors, assigns and creditors, and can be modified only by a
       written instrument signed by the Indemnifying Party and AGLR. No
       Indemnifying Party shall have the right to assign this Indemnification
       Agreement or its obligations hereunder to any person or entity without
       the prior written consent of AGLR, which shall not be unreasonably
       withheld.

4.     This Indemnification Agreement shall be governed by, and construed in
       accordance with the internal laws (but not the laws concerning conflicts
       of laws) of the state of Georgia.

5.     The Indemnifying Party represents and warrants to AGLR that it is
       authorized to indemnify AGLR under the terms of this Indemnification
       Agreement, that it has all of the rights and powers necessary to do so,
       and that the individual signing below is authorized to bind the
       Indemnifying Party to its obligations under this Indemnification
       Agreement.

6.     The Indemnifying Party hereby agrees to provide AGLR with copies of
       Indemnifying Party's annual financial statements (consisting of at least
       a balance sheet and statements of income and cash flows) within 90 days
       following the end of the fiscal year to which such financial statements
       relate. If such financial statements have been reviewed or audited, the
       statements provided pursuant to the immediately preceding sentence shall
       be the reviewed or audited statements, as the case may be.

7.     The Indemnifying Party hereby agrees to notify AGLR within 45 days
       following the close of each of the first three quarters of each of
       Indemnifying Party's fiscal years if at the end of such quarter,
       Indemnifying Party's stockholders' equity, determined in accordance with
       generally accepted accounting principles consistently applied, shall be
       less than $30 million.

8.     On the date of each delivery of financial statements pursuant numbered
       paragraph 6 above, Indemnifying Party represents and warrants to AGLR
       that the balance sheet delivered by Indemnifying Party on such date
       reflects


<PAGE>   3

       all obligations, contingent or otherwise, which in accordance with
       generally accepted accounting principles should be classified upon
       Indemnifying Party's balance sheet as liabilities or disclosed in
       footnotes thereto.

9.     Notices hereunder must be given in writing (which may be a facsimile
       transmission) to be effective and shall be effective upon receipt by AGLR
       or the Indemnifying Party at the address set forth below or at such other

                     DIRECTOR RETIREMENT BENEFITS AGREEMENT


         This DIRECTOR RETIREMENT BENEFITS AGREEMENT, made and effective this

                              W I T N E S S E T H:

         WHEREAS, the Board of Directors of the Company (the "Board") by

required by paragraphs 2 or 3 of this Agreement.

         5. The Company will pay the premium for medical insurance for the

Director.

corporate seal to be hereto affixed; and the above named Director has hereto
subscribed his or her signature, all the day and year first above written.

         point of interconnection between Transporter and the pipeline system of
         Transco in Rockingham County, North Carolina ("Point of Receipt").
         Transporter shall accept deliveries at the Point of Receipt at a
         pressure sufficient to allow the gas to enter Transporter's pipeline
         system at the varying pressures that may exist in such system from
         time-to-time; provided, however, that such pressure(s) of the gas
         delivered or caused to be delivered by Shipper shall not exceed the
         maximum operating pressure(s) specified by Transporter for the Point of
         Receipt.

3.02     Shipper shall make any necessary arrangements with Transco so as to be
         able to deliver gas to Transporter at the Point of Receipt; provided,
         however, that such arrangements are compatible with the operating
         conditions on Transporter's pipeline system.

                                    ARTICLE 4
                              POINT(S) OF DELIVERY

         Transporter shall deliver to Shipper, or for the account of Shipper,
         Equivalent Quantities hereunder at the existing Point of Delivery
         between Transporter and Shipper on the southeast side of Burlington,
         North Carolina, and any future upstream points of delivery within
         Shipper's TCQ capacity entitlements. Transporter shall design its
         pipeline facilities and use reasonable efforts to deliver gas at the
         Point(s) of Delivery at a minimum pressure of not less than 550 psig.
         The maximum pressure at the Point(s) of Delivery shall not exceed the
         maximum operating pressure of Transporter's pipeline at such point(s).


                                    ARTICLE 5
                    DETERMINATION OF RECEIPTS AND DELIVERIES

5.01     Receipts and deliveries shall be allocated by Transporter according to
         a predetermined methodology administered by Transporter for the
         allocation among shippers each Day of each dt of gas which is delivered
         by Transporter at the Point(s) of Delivery. Under the current
         allocation methodology, the quantity of gas allocated each Day to each
         Shipper at the Point of Receipt shall be deemed to be, to the maximum
         extent possible, the quantities of gas delivered for such Shipper's
         account at the Point(s) of Delivery hereunder adjusted for any
         quantities attributable to fuel and line loss makeup.

5.02     Shipper shall cause Transco to provide Transporter with a predetermined
         daily allocation methodology in writing, or electronically (by
         electronic data transfer) for measured quantities based on scheduled
         quantities in advance of service each Day and prior to any intra-day
         changes pursuant to Section 7.02 below. The daily allocation
         methodology provided by Transco shall consist of rankings for
         allocation among all shippers nominating service such that receipts are
         equivalent to the quantities delivered by Transporter plus any
         quantities applicable for fuel or line loss makeup.

                                    ARTICLE 6
              DETERMINATION OF ALLOWABLE DAILY DELIVERY VARIATIONS
                              AND OVERRUN PENALTIES

6.01     Allowable daily delivery variations shall be the quantity computed as
         follows:

         (a)    During each Day of the period beginning May 1 of any Year and
                extending through the next succeeding September 30, 5 percent of
                Shipper's TCQ under this Service Agreement.


                                       4
<PAGE>   5

         (b)    During each Day of the period beginning on October 1 of any Year
                and extending through the next succeeding April 30, 3.5 percent
                of Shipper's TCQ under this Service Agreement.

6.02     Any quantity of gas taken by Shipper on any Day from Transporter in
         excess of Shipper's TCQ under this Service Agreement shall, as adjusted
         by the allowable daily delivery variations above, be an unauthorized
         daily overrun unless:

         (a)    Shipper is utilizing the firm capacity entitlements of another
                firm shipper that is not using that capacity entitlement and
                Shipper has provided prior notice to Transporter, or

         (b)    Shipper is utilizing Excess Rate Schedule CFT Service which has
                been scheduled by Shipper and allocated by Transporter on such
                Day.

6.03     In the event of a Force Majeure, Shipper's revised TCQ pursuant to
         Article 17 below shall be utilized to determine the allowable daily
         delivery variation and unauthorized daily overrun quantity and any
         penalties thereon. Notice shall be provided by Transporter to Shipper
         of such revised TCQ by telephone or telecopy. Such notice shall be
         confirmed in writing as soon as reasonably possible.

6.04     In the event on any Day Shipper takes unauthorized daily overrun
         quantities, Shipper shall pay Transporter:

         (a)    an overrun charge equal to the 100 percent load factor FT rate
                per dt for quantities up to, but not exceeding, the daily
                allowable delivery variation set forth in Section 6.01 above,
                and

         (b)    an overrun penalty of $25 per dt for each dt of unauthorized
                daily overrun quantities in excess of the daily delivery
                variation set forth in Section 6.01 above.

6.05     All overrun penalties collected by Transporter during any calendar
         year, less an amount equal to the 100 percent load factor FT rate per
         dt multiplied by the total volume of overruns, shall be directly
         refunded to each non-overrunning firm transportation shipper for the
         Month(s) in which such penalties were incurred based on each such
         non-overrunning shipper's fixed cost contribution under its service
         agreement with Transporter as a percentage of the total fixed cost
         contributions of all non-overrunning shippers under all firm service
         agreements. Such refunds shall be made by January 31 of each calendar
         year.

6.06     The payment of a penalty for an unauthorized overrun quantity shall
         under no circumstances be considered as giving Shipper the right to
         take such unauthorized overrun quantity nor shall such payment be
         considered as a substitute for any other remedy available to
         Transporter or any other shipper against the offending shipper for such
         unauthorized overrun.

                            SCHEDULING AND BALANCING

7.01     Shipper shall nominate service under this Service Agreement in advance
         of each Month or in advance of each Day in accordance with the
         nomination deadlines of Transco. Transporter, in its sole judgement,
         may waive any nomination deadlines, on a non-discriminatory basis, if
         Transporter determines that operating conditions permit. Such nominated
         quantities shall be subject to confirmation by Transporter which shall
         be based on the best operating information available to Transporter.
         Such confirmed quantity shall be deemed the scheduled quantity. Shipper
         and Transporter shall have scheduling personnel available to be
         contacted seven days a week, twenty-four hours a day.

7.02     During any Day, Shipper may request to reschedule, on a prospective
         basis, quantities scheduled pursuant to Section 7.01 above, provided
         that such quantities are consistent with rescheduled quantities and
         deadlines on Transco.

7.03     Shipper shall endeavor to balance receipts and deliveries as reasonably
         as practicable so that the quantities delivered by Transco to
         Transporter are consistent with the actual quantities taken by Shipper
         at the Point(s) of Delivery. Shipper shall have the responsibility to
         monitor daily receipts and deliveries during the Month based on the
         best information available.

7.04     Transporter shall provide its latest estimated allocation data on
         receipts and deliveries to all parties requesting such data. These
         allocated quantities will be subject to change and the data is offered
         for informational purposes only, and should not be relied on by Shipper
         for any purposes whatsoever.

                                    ARTICLE 8
                           SHIPPER'S RESPONSIBILITIES

Shipper recognizes that, as between it and Transporter, Shipper has sole control
over its physical takes of gas from Transporter's system and therefore has a
duty to refrain from taking delivery of unauthorized overrun quantities. Shipper
further recognizes that Shipper may cause hardship and economic damage to other
shippers in the event Shipper takes delivery of unauthorized overrun quantities
for which Shipper may be held accountable either through a direct cause of
action by such other shippers or as an impleaded or third party defendant in a
suit by such other shippers. In no event shall the payment of a penalty for an
overrun quantity pursuant to this Service Agreement be considered as giving
Shipper the right to take such unauthorized overrun quantity nor shall such
payment be considered as a substitute for all other rights and remedies
(including but not limited to consequential damages) available to any other
shipper against Shipper.

                         TRANSPORTER'S RESPONSIBILITIES

Transporter recognizes that it has a duty to use reasonable care and prudent
operating procedures to allow Shipper to schedule for delivery within its TCQ,
as adjusted pursuant to a Force Majeure situation or Operating Conditions, the
gas quantities available to Shipper up to the amount verified and confirmed by
Transporter based on the best operating information available to Transporter.
Transporter also recognizes that unless forces beyond Transporter 's control
(including, but not limited to, Force Majeure, or the failure of Shipper or
Shipper's gas supplier to deliver scheduled gas quantities into Transporter's
system) cause interference with Transporter's ability to redeliver, Transporter
has a duty to tender to Shipper for redelivery the gas quantities which
Transporter has verified and confirmed as available to Shipper. Transporter
further recognizes that a breach of its duties herein may cause hardship and
economic damage to Shipper, for which Shipper reserves all rights and remedies
(including but not limited to consequential damages), and for which Transporter
may be held accountable.

                                RATES AND CHARGES

10.01    For firm transportation service provided to Shipper hereunder, Shipper
         shall pay to Transporter each month the sum of the following charges:

         (a)      Reservation Charge: Shipper's TCQ multiplied by the
                  reservation rate applicable to deliveries in the rate zone in
                  which the gas is delivered and as set forth on currently
                  effective Sheet No. 1 of Transporter's tariff.

         (b)      Commodity Charge: The applicable commodity rate set forth on
                  currently effective Sheet No. 1 multiplied by the quantities
                  of gas (dts) delivered.

         (c)      Excess CFT Charge: The applicable rate set forth on currently
                  effective Sheet No. 1 multiplied by the excess CFT quantity
                  delivered during that month.

10.02    Transporter shall retain from the quantities of gas received on behalf
         of Shipper hereunder any applicable fuel and line loss make-up
         associated with the transportation service provided hereunder.
         Transporter will evaluate any fuel retention percentages applicable to
         Shipper's service on an annual basis and will make any necessary
         filings with the NCUC to reflect any changes at least thirty (30) days
         prior to April 1 of each calendar year.

10.03    Transporter shall have the right, from time-to-time, through filings
         with the governmental agency having jurisdiction to seek to change the
         rates or allowance for fuel, and to change the other terms and
         conditions of this Service Agreement, without limitation or
         reservation; provided, however, that (a) the character of firm service,
         (b) the term, (c) the quantities, (d) the Point(s) of Receipt and
         Delivery, and (e) the delivery pressure shall not be subject to change
         hereunder without mutual agreement of the parties. Shipper shall have
         the right to



                                       7
<PAGE>   8

         oppose any of the foregoing and to seek other changes to the terms and
         conditions of this Service Agreement to the extent that Shipper is
         legally permitted to do so under applicable provision(s) of law.
         Notwithstanding the foregoing, Transporter agrees to propose in any
         subsequent rate cases a cost allocation and/or rate design for firm
         deliveries upstream of Burlington, North Carolina that reasonably
         approximate the rates Shipper would have paid if the costs of the
         existing firm service had remained in the utility rate bases of PSNC
         and Piedmont and in the absence of the merger of Transporter and
         Cardinal Pipeline Company, LLC.

                                 QUALITY OF GAS

11.01    The parties hereto recognize that the natural gas delivered for
         transportation hereunder will necessarily be commingled in
         Transporter's pipeline system with gas received from other sources, and
         that the specific gas delivered to Transporter cannot be redelivered
         for Shipper's account. It is further agreed that the natural gas
         delivered to and by Transporter hereunder shall be merchantable natural
         gas.

11.02    All gas delivered to Transporter for Shipper and redelivered by
         Transporter to Shipper shall meet the quality standards for
         transportation on the interstate pipeline system of Transco as amended
         from time-to-time.

12.01    The unit of the natural gas deliverable hereunder shall be a Dekatherm
         of gas on the measurement basis hereinafter set forth.

12.02    The quantity and the Heating Value of the natural gas delivered by
         Transporter to or for the account of Shipper or delivered by Shipper to
         Transporter for redelivery shall be determined as follows:

         (i)      The unit of volume for the purpose of measurement shall be one
                  (1) Cubic Foot of gas at a temperature of 60 degrees
                  Fahrenheit and at an absolute pressure of fourteen and
                  seventy-three hundredths (14.73) pounds per square inch.

         (ii)     The unit of weight for the purpose of measurement shall be one
                  (1) pound mass of gas.

         (iii)    The average absolute atmospheric pressure shall be assumed to
                  be 14.73 pounds per square inch.

         (iv)     The temperature of the gas flowing through the meters, when
                  necessary for computing gas quantities, shall be determined by
                  the use of a recording thermometer or other temperature
                  measuring device. The arithmetic average of the temperature
                  recorded each 24-hour day, or so much of the 24 hours as gas
                  has been flowing, shall be used

                  in computing gas quantities or instantaneous temperature
                  measurements may be applied to metering instruments to provide
                  the quantity computation.

         (v)      The specific gravity of the gas flowing through the meters,
                  when necessary for computing gas quantities, shall be, unless
                  otherwise agreed upon, determined by the use of a recording
                  gravitometer or an online process type gas chromatograph. The
                  arithmetic average of the 24-hour record, or so much of the 24
                  hours as gas has been flowing, or continuous instantaneous
                  specific gravity measurement may be applied to metering
                  instruments to provide the quality computation.

         (vi)     The deviation of the gas from Ideal Gas Laws shall be
                  calculated following the recommendations of the ANSI/API 2530
                  "Orifice Metering of Natural Gas and Other Related Hydrocarbon
                  Fluids" (A.G.A. Report No. 3) including the A.G.A. Manual for
                  Determination of Supercompressibility Factors of natural Gas
                  or the A.G.A. Transmission Measurement Committee Report No. 8
                  "Compressibility and Supercompressibility for Natural Gas and
                  Other Hydrocarbon Gases." If the composition of the gas is
                  such as to render the above procedure inapplicable, other
                  methods for determination of the deviation factors, mutually
                  agreed upon by Shipper and Transporter, shall be used.

         (vii)    The Heating Value shall be determined by either (1) the use of
                  a suitably located and acceptable make gas chromatograph or
                  (2) calculation from a fractional analysis, or (3) methods
                  outlined in A.G.A. Gas Measurement Committee Report No. 5,
                  latest edition, or (4) other methods mutually acceptable.
                  Dekatherms delivered shall be determined by either (1)
                  multiplying the Mcf delivered by a fraction the numerator of
                  which is the Btu per cubic foot and the denominator of which
                  is 1,000 or (2) multiplying the pounds mass delivered by a
                  fraction the numerator of which is the Btu per pound mass and
                  the denominator of which is 1,000,000.

12.03    Unless otherwise agreed to, Transporter will install, maintain, own and
         operate, at its own expense, at or near each Point of Receipt and each
         Point of Delivery, measuring stations properly equipped with standard
         orifice meters, flange connections, orifice plates and other necessary
         measuring equipment or other standard type meter suitable for the
         purpose by which the quantity of natural gas shall be measured and
         determined. The Heating Value of natural gas received or delivered
         shall be measured and determined as provided above. Orifice meters
         where used shall be installed and operated in accordance with ANSI/API
         "Orifice Metering of Natural Gas and Other Related Hydrocarbon Fluids,"
         latest revision, and shall include the use of straightening vanes.

12.04    Shipper acting jointly with Transporter may install, maintain and
         operate, at its own expense, such check measuring equipment as desired,
         provided that such equipment shall be so installed as not to interfere
         with the operation of Transporter 's measuring equipment.

12.05    Each party shall have the right to be present at the time of
         installing, reading, cleaning, changing, repairing, inspecting,
         testing, calibrating, or adjusting done in connection with



                                       9
<PAGE>   10

         measuring equipment involved in billing and used in measuring or
         checking the measurement of receipts and deliveries. The records from
         such measuring equipment shall remain the property of their owner, but
         upon request, each will submit to the other its records and charts,
         together with calculations therefrom for inspection and verification,
         subject to return within ten (10) days after receipt thereof.

12.06    All installations of measurement equipment applying to or affecting
         receipts and deliveries shall be made in such manner as to permit an
         accurate determination of the quantity of natural gas delivered and
         ready verification of the accuracy of measurement. Care shall be
         exercised by Transporter and Shipper in the installation, maintenance
         and operation of pressure regulating equipment so as to prevent any
         inaccuracy in the determination of the quantity of gas received or
         delivered hereunder.

12.07    In the event a meter is out of service, or registering inaccurately,
         the quantity of natural gas received or delivered shall be determined,

         (i)    By using the registration of any check meter or meters if
                installed and accurately registering, or, in the absence of (i),

         (ii)   By correcting the error or the percentage of error if
                ascertainable by calibration, test, or mathematical calculation,
                or in the absence of both (i) and (ii), then

         (iii)  By estimating the quantity of receipts or deliveries during
                periods under similar conditions when the meter was registering
                accurately.

12.08    The accuracy of Transporter 's measurement equipment shall be verified
         by Transporter at reasonable intervals, and, if requested, in the
         presence of representatives of Shipper, but Transporter shall not be
         required as a matter of routine to verify the accuracy of such
         equipment more frequently than once in any thirty (30) day period.

12.09    If, upon test, any measurement equipment, including recording gas
         chromatograph, is found to be in error not more than two percent (2%),
         previous recording of such equipment shall be considered accurate in
         computing receipts and deliveries; but such equipment shall be adjusted
         at once to record correctly. If, upon test, any measurement equipment
         shall be found to be inaccurate by an amount exceeding two percent (2%)
         at a recording corresponding to the average hourly rate of flow for the
         period since the last preceding test, then any previous recordings of
         such equipment shall be corrected to zero error for any period which is
         definitely known, but, in case the period is not known definitely or
         agreed upon, such correction shall be for a period extending over
         one-half of the time elapsed since the date of the last test, not
         exceeding a correction period of 16 days.

12.10    Transporter and Shipper shall preserve all original or equivalent
         electronic test data, charts, or other similar records for a period
         required by the applicable rules of regulatory agencies having
         jurisdiction.

                                TERM OF AGREEMENT

13.01    This Agreement shall be effective as of the date hereof and shall
         continue in effect until the expiration of the twentieth (20th)
         Contract Year, and year-to-year thereafter, subject to termination by
         either party at the end of the Contract Year or any year thereafter
         upon two years advance written notice to the other party.

13.02    Firm transportation service hereunder shall commence at the Effective
         Time of the Merger between Transporter and Cardinal Pipeline Company,
         LLC as defined in the Agreement and Plan of Merger, as amended.

                                   ARTICLE 14
                               BILLING AND PAYMENT

14.01    Transporter shall render its bill on or before the first Day of each
         Month for the Reservation Charges due for service rendered hereunder
         during the preceding calendar Month. On or before the 10th day of each
         Month, Transporter shall render its bill for any remaining charges for
         gas services rendered during the preceding calendar Month. Such bill
         shall include any Commodity Charges, Excess CFT Charges, any
         adjustments to the charges billed on the first day of the Month, and
         any penalties for unauthorized overruns applicable to the Month for
         which the bill is rendered.

14.02    Transporter and Shipper shall each, upon request of the other, deliver
         to the other for examination such pertinent records and charts as shall
         be necessary to verify the accuracy of any statement, chart, or
         computation made by either of them under or pursuant to any of the
         provisions hereof.

14.03    Shipper, except as otherwise hereinafter provided, shall pay to
         Transporter by wire transfer of immediately available funds on or
         before the 10th day of each Month for the Reservation Charges due for
         service rendered by Transporter hereunder during the preceding month
         and billed by Transporter in the statement for such month, and on or
         before the 20th day for each Month for any remaining charges for
         services which are due hereunder. If the normal payment due date is a
         Saturday, Sunday or holiday, this payment is due the following business
         Day.

14.04    Should Shipper fail to pay all of the amount of any bill for service
         hereunder when such amount is due, interest on the unpaid portion of
         such amount shall accrue at the rate equal to the prime rate of
         CitiBank, N.A. or its successor, calculated from the due date until the
         date of payment. If such failure to pay continues for thirty (30) days
         after payment is due, Transporter, in addition to any other remedy it
         may have hereunder, may suspend further transportation of natural gas
         hereunder until such amount is paid; provided, however, that if Shipper
         in good faith shall dispute the amount of any such bill or any part
         hereof, and shall pay to Transporter such amount as it concedes to be
         correct, and at any time thereafter within thirty (30) days of a demand
         made by Transporter, shall furnish good and sufficient surety



                                       11
<PAGE>   12

         bond, guaranteeing payment to Transporter of the amount ultimately
         found to be due under such bill after a final determination, which may
         be reached either by agreement between the parties, arbitration or
         judgment for a court or by any regulatory authority having
         jurisdiction, then Transporter shall not be entitled to suspend further
         delivery of natural gas unless and until default be made in the
         conditions of such bond.

14.05    If within twelve (12) months of the date of payment, it shall be found
         that Shipper has been overcharged or undercharged in any form
         whatsoever under the provisions hereof, and Shipper shall have actually
         paid the bill(s) containing such overcharge or undercharge, then within
         thirty (30) days after the final determination thereof, Transporter
         shall refund the amount of any such overcharge with interest thereon at
         the prime rate of the CitiBank N.A. or its successor from the time such
         overcharge was paid to the date of refund, and Shipper shall pay the
         amount of any such undercharge but without interest.

14.06    In the event an error is discovered in the amount billed in any
         statement rendered by Transporter, such error shall be adjusted within
         thirty (30) days of the determination thereof, provided that claim
         therefor shall have been made within sixty (60) days from the date of
         discovery of such error, but in any event, within twelve (12) months
         from the date of payment.

14.07    If rendition of a bill to Shipper by Transporter is delayed beyond the
         date specified herein, then Shipper shall pay such bill by wire
         transfer within ten (10) days after rendition thereof.

                               ASSUMPTION OF RISK

15.01    As between the parties hereto, Shipper shall be deemed to be in control
         and possession of the gas to be transported hereunder until it shall
         have been delivered to Transporter at the Point of Receipt; and Shipper
         shall be deemed to be in control and possession of the gas to be
         transported hereunder after delivery for Shipper's account at the Point
         of Delivery. Transporter shall be deemed to be in control and
         possession of such gas after the delivery thereof to Transporter at the
         Point of Receipt and prior to delivery thereof for Shipper's account at
         the Point of Delivery.

15.02    Transporter shall have no responsibility with respect to any gas to be
         transported hereunder or on account of anything which may be done,
         happen or arise with respect thereto until it is delivered into its
         facilities at the Point of Receipt and after it is received for
         Shipper's account at the Point of Delivery. Shipper shall have no
         responsibility with respect to such gas or on account of anything which
         may be done, happen or arise with respect thereto after causing the
         delivery thereof to Transporter at the Point of Receipt and prior to
         delivery thereof for Shipper's account at the Point of Delivery.

                                   WARRANTIES

Shipper warrants for itself, its successors and assigns, that it will at the
time of delivery to Transporter for transportation have good and merchantable
title to or the legal right to tender all gas delivered hereunder free and clear
of all liens, encumbrances and claims. Shipper shall indemnify Transporter and
save it harmless from all suits, actions, debts, accounts, damages, costs,
losses and expenses arising from or out of adverse claims of any or all persons
to said gas, including claims for any royalties, taxes, license fees or charges
applicable to such gas or to the delivery thereof to Transporter for
transportation under this Service Agreement.

                                  FORCE MAJEURE

17.01    In the event of either party being rendered unable, wholly or in part,
         by Force Majeure or Operating Conditions to carry out its obligations
         other than (i) the obligation of Shipper to pay the monthly Reservation
         Charge due Transporter (except as provided in 17.03 below), and (ii)
         the obligation to make payment of amounts accrued and due at the time
         thereof, it is agreed that on such party's giving notice and full
         particulars of such Force Majeure or Operating Conditions in writing or
         by telecopy to the other party within a reasonable time after the
         occurrence of the cause relied on, the obligation of both parties, so
         far as they are affected by such Force Majeure or Operating Conditions,
         shall be suspended during the continuance of any inability so caused,
         but for no longer period, and such cause shall so far as possible be
         remedied with all reasonable dispatch. Neither party shall be liable in
         damages to the other for any act, omission or circumstance occasioned
         by, or in consequence of, Force Majeure or Operating Conditions, as
         herein defined in this Service Agreement.

17.02    If, due to Force Majeure or Operating Conditions, Transporter is unable
         to receive, transport or redeliver gas tendered by Shipper for
         transportation or if Shipper is unable to deliver gas to Transporter,
         then Transporter, upon providing as much notice as possible under all
         of the circumstances, shall order reduction of Shipper's TCQ to the
         extent necessary depending upon the type and location of the
         occurrence, in accordance with the following procedures: Transporter
         shall order allocation, to the extent necessary, of affected
         transportation service to all shippers proportionate to each shipper's
         TCQ. Where Transporter's ability to render service is impaired in a
         particular segment of Transporter's system, then such allocation shall
         be effected only in that segment of Transporter's system in which
         service has been impaired.

17.03    Such causes or contingencies affecting the performance by either party,
         however, shall not relieve it of liability unless such party shall give
         notice and full particulars of such cause or contingency in writing or
         by telecopy to the other party within a reasonable time after the
         occurrence relied upon, nor shall such causes or contingencies
         affecting the performance by either party relieve it of liability in
         the event of its failure to use due diligence to remedy the situation
         and remove the cause with all reasonable dispatch, provided that the
         resolution of strikes, lockouts or other labor disputes shall be within
         the sole discretion of the parties involved therein. Such causes or
         contingencies affecting the performance by either party



                                       13
<PAGE>   14

         shall not relieve Shipper from its obligations to make payments of
         monthly Reservation Charge except to the extent of Transporter's
         negligence or willful misconduct.

                                  MISCELLANEOUS

19.01    Transporter grants the right to Shipper to direct tie-ins between its
         distribution system and Transporter's intrastate pipeline for the
         purpose of serving its franchise area subject to the negotiation of
         mutual agreeable terms and conditions (including reimbursement
         arrangements and/or incremental charges and the construction, operation
         and maintenance specifications for such tie-ins) which will be set
         forth in an Interconnect and Reimbursement Agreement to be negotiated
         and executed by Shipper and Transporter.

19.02    This Agreement reflects the entire agreement between the parties with
         respect to the subject matter hereof and supersedes all prior
         agreements and understandings, oral and written, among the parties with
         respect to the subject matter hereof. This Agreement can be amended,
         restated or supplemented only by the written agreement of Transporter
         and Shipper.

19.03    No waiver by either party of any default by the other party in the
         performance of any provision, condition or requirement herein shall be
         deemed to be a waiver of, or in any manner release the other party
         from, performance of any other provision, condition or requirement
         herein, nor shall such waiver be deemed to be a waiver of, or in any
         manner a release of, the other party from future performance of the
         same provision, condition or requirement. Any delay or omission of
         either party to exercise any right hereunder shall not impair the
         exercise of any such right, or any like right, accruing to it
         thereafter. No waiver of a right created by this Agreement by one party
         shall constitute a waiver of such right by the other party except as
         may otherwise be required by law with respect to persons not parties
         hereto. The failure of one party to perform its obligations hereunder
         shall not release the other party from the performance of such
         obligations.

19.04    This Agreement may be assigned by Shipper without the prior consent of
         Transporter provided that Shipper remains responsible for any and all
         obligations under this Agreement.

19.05    This Agreement and the obligations of the parties hereunder are subject
         to all applicable laws, rules, orders and regulations of any
         governmental authorities having jurisdiction, and to the extent of
         conflict, such laws, rules, orders and regulations of governmental
         authorities having jurisdiction shall control.

19.06    Any provision of this Agreement that is prohibited or unenforceable
         shall be ineffective to the extent of that prohibition or
         unenforceability without invalidating the remaining provisions hereof
         or affecting the validity or enforceability of that provision in any
         other jurisdiction.

19.07    This Agreement may be executed in counterparts, each of which shall be
         deemed an original, but all of which together shall constitute one and
         the same instrument.

19.08    THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
         THE LAWS OF THE STATE OF NORTH CAROLINA. EXCLUDING, HOWEVER, ANY
         CONFLICT OF LAWS RULES OR PRINCIPLES WHICH MIGHT REFER THE CONSTRUCTION
         OR OPERATION OF THE TERMS OF THIS AGREEMENT TO THE LAWS OF ANOTHER

            Piedmont Natural Gas Company Employee Stock Purchase Plan

         The Employee Stock Purchase Plan (ESPP) was first adopted in 1986,
effective as of July 1, 1985. The purpose of the ESPP is to encourage employees
to purchase Piedmont Common Stock, thereby promoting increased interest in the
Company, and to encourage employees to remain employed. Participants elect to
have a portion of their pay withheld each pay period for periodic purchases at
90% of the average market prices for the month during which the purchase takes
place.

         The following significant changes were made in the ESPP during the year
ended October 31, 1999:

- -        The plan year was changed from a calendar year to a fiscal year ending
         October 31.

- -        Purchase dates were changed from semi-annual, June 30 and December 31,
         to quarterly, January 31, April 30, July 31 and October 31.

- -        Employees are now eligible to participate at the beginning of the
         purchase quarter following their hire date. Previously employees had to
         be employed six months before beginning participation at a purchase
         period beginning January 1 or July 1.

- -        Purchased shares are now deposited in the participant's account in
         Piedmont's Dividend Reinvestment and Stock Purchase Plan (DRIP). Stock
         certificates will only be issued from the DRIP upon the request of the
         participant. Previously stock certificates were issued to participants
         at the time of purchase.

         There are no financial statements for the ESPP. Amounts withheld from
participants are recorded as a general liability on Piedmont's books until the
purchase date. At that time, the liability is reduced to zero and shares are
issued to the DRIP as indicated above. We furnish a quarterly statement to
participants showing the number of shares purchased, the purchase price and the
balance in the account. At October 31, 1999, 546 employees were participating in
the ESPP.

           Piedmont Natural Gas Company Employee Stock Ownership Plan

                          Notes To Financial Statements

1.       Description of the Plan

         The Piedmont Natural Gas Company Employee Stock Ownership Plan (ESOP)
         was established to enable employees to acquire Piedmont Common Stock.
         Through 1986, we contributed to the ESOP amounts equal to a tax credit
         based on aggregate compensation paid or accrued to all employees under
         the ESOP. The Tax Reform Act of 1986 eliminated the tax credit
         allowance, and we have not made contributions since 1987.

         The ESOP is administered by an Administration Committee approved by our
         Board of Directors. We pay the administrative expenses of the ESOP. The
         Trust Client Services department of Wachovia Bank, N.A., serves as
         trustee and custodian. The ESOP is subject to the provisions of the
         Employee Retirement Income Security Act of 1974.

         A participant in the ESOP is defined as an active eligible employee
         with a balance in his or her ESOP account. An employee is eligible to
         participate following the later of the date of completion of at least
         1,000 hours of service during a period of 12 consecutive months or
         attainment of age 21. However, employees who reached eligibility after
         we stopped making contributions are not considered participants and no
         previous contributions have been credited to them.

         Separate accounts are maintained for each participant to reflect the
         allocation of contributions and subsequent dividend and investment
         income. Any income credited to participants is reinvested in Common
         Stock. The ESOP provides for immediate vesting.

         Distributions are made either at early retirement (age 55 and 10 years
         of service), at normal retirement (age 65), at actual retirement for a
         participant who remains employed after attaining normal retirement age,
         at permanent disability or at death of the participant. The
         Administration Committee may direct an earlier distribution following a
         participant's termination of employment, and this has been the
         practice.

         A participant who has reached age 55 and completed ten years of
         participation has the right to diversify a portion of his or her
         account balance each year during the qualified election period.

         We may terminate the ESOP at any time and may either continue
         operations until the trustee has distributed all benefits or cause the
         assets to be liquidated and distributed.

2.       Basis of Accounting

         The financial statements are presented on the accrual basis of
         accounting.

         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 estimates.

         The investment in Common Stock is valued at fair value as determined by
         quoted market prices on the New York Stock Exchange on October 31, 1999
         and 1998. Dividend income is accrued on the ex-dividend date. Purchases
         and sales of securities are recorded on a trade-date basis. Realized
         gains and losses from security transactions are reported on the average
         cost method.

3.       Gain (Loss) on Sale of Assets

         The gain (loss) on sale of assets for the years ended October 31, 1999,
         1998 and 1997, was computed as follows:

4.       Net Assets Available for Benefits

         Net assets available for benefits adjusted for the payable to
         participants for withdrawals at October 31, 1999, 1998 and 1997, were
         as follows:

5.       Tax Status

         The ESOP is qualified under Sections 401 and 409 of the Internal
         Revenue Code of 1986, as amended (the Tax Code). The Internal Revenue
         Service has informed us by letter that the ESOP, as designed, is
         qualified and the trust established under the ESOP is exempt from
         income taxes under Section 501(a) of the Tax Code. The ESOP has been
         amended since receiving the determination letter; however, we believe
         the ESOP is currently designed and being operated in compliance with
         applicable requirements of the Tax Code.

         Distributions are taxed to recipients as ordinary income, with the
         taxable amount that applies to Common Stock being the lesser of cost or
         fair market value on the date of distribution. Any increase in the
         value of Common Stock is not taxed during the period that the stock is
         held by the trust nor upon its distribution to the participant. If
         stock is sold after distribution, the sale is subject to capital gain
         or loss treatment, depending on the sales price of the stock.

Independent Auditors' Report



Piedmont Natural Gas Company
  Employee Stock Ownership Plan:

We have audited the accompanying statements of net assets available for benefits
of the Piedmont Natural Gas Company Employee Stock Ownership Plan (the Plan) as
of October 31, 1999 and 1998, and the related statements of changes in net
assets available for benefits for each of the three years in the period ended
October 31, 1999. These financial statements are the responsibility of the
Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan as of
October 31, 1999 and 1998, and the changes in net assets available for benefits
for each of the three years in the period ended October 31, 1999 in conformity
with generally accepted accounting principles.
