                                  THE COMPANY
 
     The Company is engaged in the generation, transmission, distribution and
sale of electric energy in the central portion of North Carolina and the western
portion of South Carolina, comprising the area in both States known as the
Piedmont Carolinas. Its service area, approximately two-thirds of which lies in
North Carolina, covers about 20,000 square miles with an estimated population of
4,800,000 and includes a number of cities, of which the largest are Charlotte,
Greensboro, Winston-Salem and Durham in North Carolina and Greenville and
Spartanburg in South Carolina. During 1993, the Company's electric revenues
amounted to approximately $4.3 billion, of which about 70% was derived from
North Carolina and about 30% from South Carolina. The Company ranks sixth in the
United States among investor-owned utilities in kilowatt-hour sales. Its
executive offices are located in the Power Building, 422 South Church Street,
Charlotte, North Carolina 28242-0001 (Telephone No. 704-594-0887).
 
SERVICE AREA
 
     The Company supplies electric service directly to approximately 1,700,000
residential, commercial and industrial customers in more than 200 cities, towns
and unincorporated communities in North Carolina and South Carolina. Electricity
is sold at wholesale to nine incorporated municipalities and to several private
utilities. In addition, in 1993 approximately 9% of total sales were made
through contractual arrangements to former wholesale municipal or cooperative
customers of the Company who had purchased portions of the Catawba Nuclear
Station (collectively, the "Other Catawba Joint Owners").
 
     The Company's service area is undergoing increasingly diversified
industrial development. The textile, manufacture of machinery and equipment,
chemical and chemical-related industries are of major significance to the
economy of the area. Other industrial activity includes the paper and allied
products, rubber and plastic products and various other light and heavy
manufacturing and service businesses. The largest industry served by the Company
is the textile industry, which accounted for approximately $488,000,000 of the
Company's revenues for 1993, representing 11% of electric revenues and 40% of
electric industrial revenues.
 
RATE MATTERS
 
     The North Carolina Utilities Commission ("NCUC") and The Public Service
Commission of South Carolina ("PSCSC") must approve the Company's rates for
retail sales within the respective states. The Federal Energy Regulatory
Commission must approve the Company's rates for sales to wholesale customers,
including the contractual arrangements between the Company and the Other Catawba
Joint Owners.
 
     In its most recent general rate case, the NCUC authorized a jurisdictional
rate of return on common equity of 12.50% and the PSCSC authorized a
jurisdictional rate of return on common equity of 12.25%.
 
CONSTRUCTION PROGRAM
 
     The Company's construction program and the estimated construction costs set
forth below are subject to continuing review and are revised from time to time
in light of changes in load forecasts, the Company's financial condition
(including cash flow, earnings and levels of rates), changing regulatory and
environmental standards, and other factors.

The Company's procedures for estimating construction costs (which include
allowance for funds used during construction) utilize, among other things, past
construction experience, current construction costs and allowances for
inflation.
 
     The Company anticipates that approximately 86% of the projected
construction and nuclear fuel costs for the three-year period 1994-1996 will be
financed through internally generated funds.
 
     The Company is building a combustion turbine facility in Lincoln County,
North Carolina to provide capacity at periods of peak demand. The Lincoln
Combustion Turbine Station will consist of 16 combustion turbines with a total
generating capacity of 1,184,000 KW. The estimated total cost of the facility is
approximately $500,000,000. Current plans are for ten units to begin commercial
operation by the end of 1995 and the remaining six units to begin commercial
operation before the end of 1996. The issuance in 1991 of a final air permit for
the facility by the North Carolina Division of Environmental Management has been
appealed. Legal proceedings in respect of the appeal are ongoing. The Company
believes the permit will be upheld.
 
                              RECENT DEVELOPMENTS
 
     Earnings per share of Common Stock of the Company increased 27% from $2.21
in 1992 to $2.80 in 1993. The increase was primarily due to higher kilowatt-hour
sales and a one-time charge taken in 1992 related to a refund to North Carolina
retail customers of 32c per share.
 
     Total electric sales for 1993 increased by 7.1%. Residential sales,
primarily driven by unusual weather conditions, increased by 9.4% and general
service sales increased by 6.9%. Industrial sales increased by 4.3% reflecting
continuing growth in the economy of the Company's service area, with textile
sales up 2.3% and other industrial sales up 5.8%.
 
     On January 25, 1994, William H. Grigg was elected chairman, president and
chief executive officer of the Company, effective April 28, 1994. Currently vice
chairman of the Board of Directors with responsibility for developing corporate
policy and strategy, he will succeed William S. Lee, who has served as chairman
and chief executive officer of the Company since 1982. Mr. Grigg joined the
Company in 1963 and during his career has served in a number of capacities,
including executive vice president, vice president, finance, and general counsel
of the Company.
 
     The Company experienced a new all-time peak load of 16,070,000 KW on
January 19, 1994 during extremely cold weather. The Company's previous all-time
peak load of 15,720,000 KW occurred on July 29, 1993 during unusually hot
weather. The 1992-1993 winter peak load of 13,314,000 KW occurred on February
19, 1993.
 
     On March 17, 1994, the Company, together with the Other Catawba Joint
Owners, settled the lawsuit initiated by the Company on March 22, 1990 against
Westinghouse Electric Corporation seeking damages for supplying to the McGuire
and Catawba Nuclear Stations steam generators that were alleged to be defective
in design, workmanship and materials and that would require replacement well
short of their stated design life. While the terms of the settlement may not be
disclosed pursuant to court order, the Company believes the litigation was
settled on terms that provided satisfactory consideration to the Company. Such
settlement will not have a material effect on the Company's results of
operations or financial position.

     For a recent reported price for the Common Stock, see the cover page of
this Prospectus.
 
     The Company has paid cash dividends on its Common Stock in each year since
1926, and the Common Stock dividend has been increased in each of the last 18
years. Future dividends will depend upon future earnings, the financial
condition of the Company and other factors affecting dividend policy that are
not presently determinable.
 
     The Company has a Stock Purchase and Dividend Reinvestment Plan pursuant to
which holders of its Common Stock may automatically reinvest their Common Stock
dividends in shares of the Company's Common Stock. Holders who become
participants in the Plan may also make optional cash payments (not more than
$20,000 per calendar quarter) to be invested in shares of the Company's Common
Stock.

                                USE OF PROCEEDS
 
     All of the shares of Common Stock offered hereby are being sold by the
Selling Shareholder. The Company will not receive any of the proceeds of the
Offerings.
 
                              SELLING SHAREHOLDER
 
     All of the shares of Common Stock offered hereby are being sold by The Duke
Endowment (the "Selling Shareholder"). The Selling Shareholder owns, as of the
date of this Prospectus, 26,070,200 shares of Common Stock, constituting
approximately 13% of the outstanding shares of Common Stock. Upon completion of
the Offerings and assuming that the Underwriters' over-allotment options are
exercised in full, the Selling Shareholder will own 10,070,200 shares of Common
Stock, constituting approximately 5% of the outstanding shares of Common Stock.
The Selling Shareholder has no present intention to dispose of any additional
shares of Common Stock.
 
     The Selling Shareholder is a common law trust established in 1924 by the
late James B. Duke, the founder of the Company, for educational, hospital,
religious and other charitable purposes. The Selling Shareholder has advised the
Company that its Common Stock holdings constituted approximately 77% of its
investment portfolio as of December 31, 1993 and provided almost 80% of its
income for the year then ended and that it is selling the shares of Common Stock
offered hereby to diversify its investment portfolio.
 
     The Selling Shareholder has 15 trustees, none of whom has been a director,
officer or employee of the Company or has had a material relationship with the
Company within the past three years, except for James C. Self, a trustee of the
Selling Shareholder, who served as a director of the Company from April 30, 1982
until April 23, 1992.
 
     The trustees of the Selling Shareholder are also the trustees of The Doris
Duke Trust, another common law trust established by James B. Duke, which, as of
the date of this Prospectus, owns of record 3,906,396 shares of Common Stock,
constituting approximately 2% of the outstanding shares of Common Stock. The
Selling Shareholder believes it became entitled as remainderman to a
distribution of 2,604,264 shares of such shares of Common Stock from The Doris
Duke Trust as of the date of death of its principal income beneficiary. The
Doris Duke Trust has commenced a proceeding seeking a determination as to the
entitlement to such distribution and the matter is currently in litigation.
 
     The foregoing statements with respect to the Selling Shareholder are based
upon information furnished to the Company by the Selling Shareholder.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     The authorized capital stock of the Company is divided into four classes:
Common Stock, without par value, Preferred Stock of the par value of $100 per
share ("Preferred Stock"), Preferred Stock A of the par value of $25 per share
("Preferred Stock A") and Preference Stock of the par value of $100 per share
("Preference Stock"). The number of authorized shares of Common Stock, Preferred
Stock, Preferred Stock A and Preference Stock are 300,000,000, 12,500,000,
10,000,000 and 1,500,000, respectively. As of the date hereof, there are
currently outstanding 14 series of Preferred Stock, 5 series of Preferred Stock
A and no series of Preference Stock. The Preferred Stock, Preferred Stock A and
Preference Stock together are hereinafter sometimes called the "Preferred
Stocks."
 
     The following statements are summaries of certain provisions with respect
to the Common Stock and the Preferred Stocks that are contained in the Company's
Restated Articles of Incorporation (the "Articles"). Reference is made to the
pertinent exhibits to the Registration Statement, which are incorporated herein
by reference, for a full and complete statement of such provisions, and the
following statements are qualified in their entirety by such reference.
 
COMMON STOCK
 
     Dividends may be paid on the Common Stock as determined by the Board of
Directors out of funds legally available therefor but only if full dividends on
all outstanding series of the Preferred Stocks for the then current and all
prior dividend periods and any required sinking fund payments with respect to
any outstanding series of such securities have been paid or provided for.
 
     The holders of the Common Stock have exclusive voting rights, except as
otherwise provided by law, on the basis of one vote per share.
 
     Whenever dividends on any part of the Preferred Stock or of the Preferred
Stock A are in arrears in an amount equivalent to the aggregate dividends
required to be paid on such Preferred Stock or such Preferred Stock A in any
period of 12 calendar months, the holders of the Preferred Stock as a class have
the exclusive right to elect a majority of the authorized number of directors of
the Company and the holders of the Preferred Stock A as a class have the
exclusive right to elect two directors, which rights cease whenever all accrued
and unpaid dividends have been paid in full. Whenever six quarterly dividends on
any outstanding series of the Preference Stock are in arrears or any required
sinking fund payments are in default, the holders of the Preference Stock as a
class have the exclusive right to elect two directors of the Company which right
ceases whenever all dividends and required sinking fund obligations in default
have been paid in full or provided for. In addition, the consent of the holders
of specified percentages of the Preferred Stock, Preferred Stock A or of the
Preference Stock, or some or all of the holders of such classes, is required in
connection with certain increases in authorized amounts or changes in stock
senior to the Common Stock or in connection with any sale of substantially all
of the Company's assets or certain mergers.
 
     The holders of the Common Stock are entitled in liquidation to share
ratably in the assets of the Company after required preferential payments to the
holders of the Preferred Stocks.
 
     The holders of the Common Stock have no cumulative voting rights, no
preemptive rights and no conversion rights. The Common Stock is not subject to
redemption or to any further calls or assessments and is not entitled to the
benefit of any sinking fund provisions.
 
     The Company serves as transfer agent and First Union National Bank of North
Carolina, Charlotte, N.C. serves as registrar for the Common Stock.
 
PREFERRED STOCKS
 
     The Preferred Stock, Preferred Stock A and Preference Stock may be issued
in one or more series from time to time upon such consideration (not less than
the par value thereof), upon such terms, and in such manner, and with such
variations as to dividend rates (or method of calculation
 
                                       11
<PAGE>   12
 
thereof), dividend payment dates, terms of redemption (at prices not less than
the par value thereof), sinking fund provisions and conversion rights as may be
determined by the Board of Directors without the approval of the shareholders.
 
CHANGE OF CONTROL
 
     The Articles provide for a classified Board of Directors consisting of
three classes. Each class consists, as nearly as may be possible, of one-third
of the total number of directors constituting the entire Board of Directors. At
each annual meeting of shareholders, successors to the class of directors whose
term expires at that annual meeting are elected for a three-year term and until
their respective successors are elected and qualified.
 
     Certain provisions of the Articles require a greater than majority vote of
the Company's shareholders. Under the Articles the affirmative vote of at least
80% of the combined voting power of the then outstanding shares of stock of all
classes of the Company entitled to vote generally in the election of directors
of the Company voting together as a single class is required to alter, amend or
repeal any of the provisions, including the percentage vote requirement, of the
Article that classifies the Board of Directors into three classes, specifies the
minimum and maximum size of the Board, provides that directors may be removed
only for cause, provides that newly created directorships and vacancies on the
Board may be filled only by the remaining directors and provides that no
decrease in the number of directors constituting the Board of Directors may
shorten the term of any incumbent director.
 
     The provisions authorizing the Board of Directors to issue the Preferred
Stocks without shareholder approval, the classified Board of Directors and the
provisions requiring a greater than majority vote of shareholders in certain
instances could have the effect of delaying, deferring or preventing a change in
control of the Company or the removal of existing management.

     Under the terms and conditions of the Underwriting Agreement, the U.S.
Underwriters are committed to take and pay for all of the shares offered hereby,
if any are taken.
 
     The U.S. Underwriters propose to offer the shares of Common Stock in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus, and in part to certain securities dealers at such
price less a concession of $.55 per share. The U.S. Underwriters may allow, and
such dealers may reallow, a concession not in excess of $.10 per share to
certain brokers and dealers. After the shares of Common Stock are released for
sale to the public, the offering price and other selling terms may from time to
time be varied by the representatives.
 
     The Company and the Selling Shareholder have entered into an underwriting
agreement (the "International Underwriting Agreement") with the underwriters of
the International Offering (the "International Underwriters") providing for the
concurrent offer and sale of 2,800,000 shares of Common Stock in an
international offering outside the United States. The offering price and
aggregate underwriting discount per share for the two offerings are identical.
The closing of the offering made hereby is a condition to the closing of the
international offering, and vice versa. The representatives of the International
Underwriters are Goldman Sachs International, Merrill Lynch International
Limited and Morgan Stanley & Co. International Limited.
 
     Pursuant to an agreement between the U.S. and International Underwriting
Syndicates (the "Agreement Between") relating to the Offerings, each of the U.S.
Underwriters named herein has agreed that, as a part of the distribution of the
shares offered hereby and subject to certain exceptions, it will offer, sell or
deliver the shares offered hereby and other shares of Common Stock, directly or
indirectly, only in the United States of America (including the States and the
District of Columbia), its territories, possessions and other areas subject to
its jurisdiction (as used in this paragraph, the "United States") and to U.S.
persons, which term shall mean for purposes of this paragraph (a) individuals
resident in the United States and (b) corporations, partnerships or other
entities organized in or under the laws of the United States or any political
subdivision thereof and whose office most directly involved with the purchase is
located in the United States. Each of the International Underwriters has agreed
pursuant to the Agreement Between that, as part of the distribution of the
shares offered as part of the International Offering and subject to certain
exceptions, it (i) will not offer, sell or deliver shares of Common Stock,
directly or indirectly, (a) in the United States or to any U.S. persons or (b)
to any person whom it believes intends to reoffer, resell or deliver the shares
in the United States or to any U.S. persons and (ii) will cause any dealer to
whom it may sell such shares at any concession to agree to observe a similar
restriction.

<PAGE>   15
 
     Pursuant to the Agreement Between, sales may be made between the U.S.
Underwriters and the International Underwriters of such number of shares of
Common Stock as may be mutually agreed. The price of any shares so sold shall be
the initial public offering price, less an amount not greater than the selling
concession.
 
     The Selling Shareholder has granted the U.S. Underwriters an option
exercisable for 30 days after the date of this Prospectus to purchase up to an
aggregate of 1,600,000 additional shares of Common Stock solely to cover
over-allotments, if any. If the U.S. Underwriters exercise their over-allotment
option, the U.S. Underwriters have severally agreed, subject to certain
conditions, to purchase approximately the same percentage thereof that the
number of shares to be purchased by each of them, as shown in the foregoing
table, bears to the 11,200,000 shares of Common Stock offered hereby. The
Selling Shareholder has granted the International Underwriters an option
exercisable for 30 days after the date of this Prospectus to purchase up to an
aggregate of 400,000 additional shares of Common Stock solely to cover
over-allotments, if any. Any shares of Common Stock purchased pursuant to such
over-allotment options will be purchased at the initial public offering price
per share less the underwriting discount, as set forth on the cover page of this
Prospectus.
 
     The Selling Shareholder has agreed not to offer, sell or otherwise dispose
of any Common Stock, except for the shares of Common Stock offered in connection
with the Offerings, for a period of 180 days after the date of this Prospectus
without the prior written consent of the representatives of the Underwriters.
The Company has agreed with the Underwriters not to offer, sell, contract to
sell or otherwise dispose of any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock, except
pursuant to employee benefit plans and the Stock Purchase and Dividend
Reinvestment Plan, for a period of 90 days after the date of this Prospectus
without the prior written consent of the representatives of the Underwriters.
 
     The Underwriters and certain affiliates thereof engage in transactions with
and perform services for the Company and its affiliates in the ordinary course
of business.
 
     The Company has agreed to indemnify the several Underwriters against
certain liabilities, including liabilities under the Securities Act of 1933.

Spartanburg in South Carolina. During 1993, the Company's electric revenues
amounted to approximately $4.3 billion, of which about 70% was derived from
North Carolina and about 30% from South Carolina. The Company ranks sixth in the
United States among investor-owned utilities in kilowatt-hour sales. Its
executive offices are located in the Power Building, 422 South Church Street,
Charlotte, North Carolina 28242-0001 (Telephone No. 704-594-0887).
 
SERVICE AREA
 
     The Company supplies electric service directly to approximately 1,700,000
residential, commercial and industrial customers in more than 200 cities, towns
and unincorporated communities in North Carolina and South Carolina. Electricity
is sold at wholesale to nine incorporated municipalities and to several private
utilities. In addition, in 1993 approximately 9% of total sales were made
through contractual arrangements to former wholesale municipal or cooperative
customers of the Company who had purchased portions of the Catawba Nuclear
Station (collectively, the "Other Catawba Joint Owners").
 
     The Company's service area is undergoing increasingly diversified
industrial development. The textile, manufacture of machinery and equipment,
chemical and chemical-related industries are of major significance to the
economy of the area. Other industrial activity includes the paper and allied
products, rubber and plastic products and various other light and heavy
manufacturing and service businesses. The largest industry served by the Company
is the textile industry, which accounted for approximately $488,000,000 of the
Company's revenues for 1993, representing 11% of electric revenues and 40% of
electric industrial revenues.
 
RATE MATTERS
 
     The North Carolina Utilities Commission ("NCUC") and The Public Service
Commission of South Carolina ("PSCSC") must approve the Company's rates for
retail sales within the respective states. The Federal Energy Regulatory
Commission must approve the Company's rates for sales to wholesale customers,
including the contractual arrangements between the Company and the Other Catawba
Joint Owners.
 
     In its most recent general rate case, the NCUC authorized a jurisdictional
rate of return on common equity of 12.50% and the PSCSC authorized a
jurisdictional rate of return on common equity of 12.25%.
 
CONSTRUCTION PROGRAM
 
     The Company's construction program and the estimated construction costs set
forth below are subject to continuing review and are revised from time to time
in light of changes in load forecasts, the Company's financial condition
(including cash flow, earnings and levels of rates), changing regulatory and
environmental standards, and other factors.

The Company's procedures for estimating construction costs (which include
allowance for funds used during construction) utilize, among other things, past
construction experience, current construction costs and allowances for
inflation.
 
     The Company anticipates that approximately 86% of the projected
construction and nuclear fuel costs for the three-year period 1994-1996 will be
financed through internally generated funds.
 
     The Company is building a combustion turbine facility in Lincoln County,
North Carolina to provide capacity at periods of peak demand. The Lincoln
Combustion Turbine Station will consist of 16 combustion turbines with a total
generating capacity of 1,184,000 KW. The estimated total cost of the facility is
approximately $500,000,000. Current plans are for ten units to begin commercial
operation by the end of 1995 and the remaining six units to begin commercial
operation before the end of 1996. The issuance in 1991 of a final air permit for
the facility by the North Carolina Division of Environmental Management has been
appealed. Legal proceedings in respect of the appeal are ongoing. The Company
believes the permit will be upheld.
 
                              RECENT DEVELOPMENTS
 
     Earnings per share of Common Stock of the Company increased 27% from $2.21
in 1992 to $2.80 in 1993. The increase was primarily due to higher kilowatt-hour
sales and a one-time charge taken in 1992 related to a refund to North Carolina
retail customers of 32c per share.
 
     Total electric sales for 1993 increased by 7.1%. Residential sales,
primarily driven by unusual weather conditions, increased by 9.4% and general
service sales increased by 6.9%. Industrial sales increased by 4.3% reflecting
continuing growth in the economy of the Company's service area, with textile
sales up 2.3% and other industrial sales up 5.8%.
 
     On January 25, 1994, William H. Grigg was elected chairman, president and
chief executive officer of the Company, effective April 28, 1994. Currently vice
chairman of the Board of Directors with responsibility for developing corporate
policy and strategy, he will succeed William S. Lee, who has served as chairman
and chief executive officer of the Company since 1982. Mr. Grigg joined the
Company in 1963 and during his career has served in a number of capacities,
including executive vice president, vice president, finance, and general counsel
of the Company.
 
     The Company experienced a new all-time peak load of 16,070,000 KW on
January 19, 1994 during extremely cold weather. The Company's previous all-time
peak load of 15,720,000 KW occurred on July 29, 1993 during unusually hot
weather. The 1992-1993 winter peak load of 13,314,000 KW occurred on February
19, 1993.
 
     On March 17, 1994, the Company, together with the Other Catawba Joint
Owners, settled the lawsuit initiated by the Company on March 22, 1990 against
Westinghouse Electric Corporation seeking damages for supplying to the McGuire
and Catawba Nuclear Stations steam generators that were alleged to be defective
in design, workmanship and materials and that would require replacement well
short of their stated design life. While the terms of the settlement may not be
disclosed pursuant to court order, the Company believes the litigation was
settled on terms that provided satisfactory consideration to the Company. Such
settlement will not have a material effect on the Company's results of
operations or financial position.

     For a recent reported price for the Common Stock, see the cover page of
this Prospectus.
 
     The Company has paid cash dividends on its Common Stock in each year since
1926, and the Common Stock dividend has been increased in each of the last 18
years. Future dividends will depend upon future earnings, the financial
condition of the Company and other factors affecting dividend policy that are
not presently determinable.
 
     The Company has a Stock Purchase and Dividend Reinvestment Plan pursuant to
which holders of its Common Stock may automatically reinvest their Common Stock
dividends in shares of the Company's Common Stock. Holders who become
participants in the Plan may also make optional cash payments (not more than
$20,000 per calendar quarter) to be invested in shares of the Company's Common
Stock.

                                USE OF PROCEEDS
 
     All of the shares of Common Stock offered hereby are being sold by the
Selling Shareholder. The Company will not receive any of the proceeds of the
Offerings.
 
                              SELLING SHAREHOLDER
 
     All of the shares of Common Stock offered hereby are being sold by The Duke
Endowment (the "Selling Shareholder"). The Selling Shareholder owns, as of the
date of this Prospectus, 26,070,200 shares of Common Stock, constituting
approximately 13% of the outstanding shares of Common Stock. Upon completion of
the Offerings and assuming that the Underwriters' over-allotment options are
exercised in full, the Selling Shareholder will own 10,070,200 shares of Common
Stock, constituting approximately 5% of the outstanding shares of Common Stock.
The Selling Shareholder has no present intention to dispose of any additional
shares of Common Stock.
 
     The Selling Shareholder is a common law trust established in 1924 by the
late James B. Duke, the founder of the Company, for educational, hospital,
religious and other charitable purposes. The Selling Shareholder has advised the
Company that its Common Stock holdings constituted approximately 77% of its
investment portfolio as of December 31, 1993 and provided almost 80% of its
income for the year then ended and that it is selling the shares of Common Stock
offered hereby to diversify its investment portfolio.
 
     The Selling Shareholder has 15 trustees, none of whom has been a director,
officer or employee of the Company or has had a material relationship with the
Company within the past three years, except for James C. Self, a trustee of the
Selling Shareholder, who served as a director of the Company from April 30, 1982
until April 23, 1992.
 
     The trustees of the Selling Shareholder are also the trustees of The Doris
Duke Trust, another common law trust established by James B. Duke, which, as of
the date of this Prospectus, owns of record 3,906,396 shares of Common Stock,
constituting approximately 2% of the outstanding shares of Common Stock. The
Selling Shareholder believes it became entitled as remainderman to a
distribution of 2,604,264 shares of such shares of Common Stock from The Doris
Duke Trust as of the date of death of its principal income beneficiary. The
Doris Duke Trust has commenced a proceeding seeking a determination as to the
entitlement to such distribution and the matter is currently in litigation.
 
     The foregoing statements with respect to the Selling Shareholder are based
upon information furnished to the Company by the Selling Shareholder.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     The authorized capital stock of the Company is divided into four classes:
Common Stock, without par value, Preferred Stock of the par value of $100 per
share ("Preferred Stock"), Preferred Stock A of the par value of $25 per share
("Preferred Stock A") and Preference Stock of the par value of $100 per share
("Preference Stock"). The number of authorized shares of Common Stock, Preferred
Stock, Preferred Stock A and Preference Stock are 300,000,000, 12,500,000,
10,000,000 and 1,500,000, respectively. As of the date hereof, there are
currently outstanding 14 series of Preferred Stock, 5 series of Preferred Stock
A and no series of Preference Stock. The Preferred Stock, Preferred Stock A and
Preference Stock together are hereinafter sometimes called the "Preferred
Stocks."
 
     The following statements are summaries of certain provisions with respect
to the Common Stock and the Preferred Stocks that are contained in the Company's
Restated Articles of Incorporation (the "Articles"). Reference is made to the
pertinent exhibits to the Registration Statement, which are incorporated herein
by reference, for a full and complete statement of such provisions, and the
following statements are qualified in their entirety by such reference.
 
COMMON STOCK
 
     Dividends may be paid on the Common Stock as determined by the Board of
Directors out of funds legally available therefor but only if full dividends on
all outstanding series of the Preferred Stocks for the then current and all
prior dividend periods and any required sinking fund payments with respect to
any outstanding series of such securities have been paid or provided for.
 
     The holders of the Common Stock have exclusive voting rights, except as
otherwise provided by law, on the basis of one vote per share.
 
     Whenever dividends on any part of the Preferred Stock or of the Preferred
Stock A are in arrears in an amount equivalent to the aggregate dividends
required to be paid on such Preferred Stock or such Preferred Stock A in any
period of 12 calendar months, the holders of the Preferred Stock as a class have
the exclusive right to elect a majority of the authorized number of directors of
the Company and the holders of the Preferred Stock A as a class have the
exclusive right to elect two directors, which rights cease whenever all accrued
and unpaid dividends have been paid in full. Whenever six quarterly dividends on
any outstanding series of the Preference Stock are in arrears or any required
sinking fund payments are in default, the holders of the Preference Stock as a
class have the exclusive right to elect two directors of the Company which right
ceases whenever all dividends and required sinking fund obligations in default
have been paid in full or provided for. In addition, the consent of the holders
of specified percentages of the Preferred Stock, Preferred Stock A or of the
Preference Stock, or some or all of the holders of such classes, is required in
connection with certain increases in authorized amounts or changes in stock
senior to the Common Stock or in connection with any sale of substantially all
of the Company's assets or certain mergers.
 
     The holders of the Common Stock are entitled in liquidation to share
ratably in the assets of the Company after required preferential payments to the
holders of the Preferred Stocks.
 
     The holders of the Common Stock have no cumulative voting rights, no
preemptive rights and no conversion rights. The Common Stock is not subject to
redemption or to any further calls or assessments and is not entitled to the
benefit of any sinking fund provisions.
 
     The Company serves as transfer agent and First Union National Bank of North
Carolina, Charlotte, N.C. serves as registrar for the Common Stock.
 
PREFERRED STOCKS
 
     The Preferred Stock, Preferred Stock A and Preference Stock may be issued
in one or more series from time to time upon such consideration (not less than
the par value thereof), upon such terms, and in such manner, and with such
variations as to dividend rates (or method of calculation
 
                                       11
<PAGE>   28
 
thereof), dividend payment dates, terms of redemption (at prices not less than
the par value thereof), sinking fund provisions and conversion rights as may be
determined by the Board of Directors without the approval of the shareholders.
 
CHANGE OF CONTROL
 
     The Articles provide for a classified Board of Directors consisting of
three classes. Each class consists, as nearly as may be possible, of one-third
of the total number of directors constituting the entire Board of Directors. At
each annual meeting of shareholders, successors to the class of directors whose
term expires at that annual meeting are elected for a three-year term and until
their respective successors are elected and qualified.
 
     Certain provisions of the Articles require a greater than majority vote of
the Company's shareholders. Under the Articles the affirmative vote of at least
80% of the combined voting power of the then outstanding shares of stock of all
classes of the Company entitled to vote generally in the election of directors
of the Company voting together as a single class is required to alter, amend or
repeal any of the provisions, including the percentage vote requirement, of the
Article that classifies the Board of Directors into three classes, specifies the
minimum and maximum size of the Board, provides that directors may be removed
only for cause, provides that newly created directorships and vacancies on the
Board may be filled only by the remaining directors and provides that no
decrease in the number of directors constituting the Board of Directors may
shorten the term of any incumbent director.
 
     The provisions authorizing the Board of Directors to issue the Preferred
Stocks without shareholder approval, the classified Board of Directors and the
provisions requiring a greater than majority vote of shareholders in certain
instances could have the effect of delaying, deferring or preventing a change in
control of the Company or the removal of existing management.

                     CERTAIN UNITED STATES TAX CONSEQUENCES
                          TO NON-UNITED STATES HOLDERS
 
     The following is a general discussion of certain United States federal
income and estate tax consequences to a holder of Common Stock who is not a
United States person (a "Foreign Holder") of the acquisition, ownership and
disposition of the Common Stock. For these purposes, "United States person"
means a citizen or resident (as specifically defined for United States federal
income and estate tax purposes) of the United States, a corporation, partnership
or other entity created or organized in or under the laws of the United States
or any political subdivision thereof or an estate or trust the income of which
is subject to United States federal income taxation regardless of its source.
The discussion does not address the particular facts and circumstances of each
Foreign Holder's situation. Foreign Holders are urged to consult their own tax
advisors with respect to the United States federal income and estate tax
consequences of acquiring, holding and disposing of the Common Stock, as well as
any tax consequences arising under the laws of any state, municipality or other
taxing jurisdiction.
 
DIVIDENDS
 
     In general, dividends paid to a Foreign Holder will be subject to United
States withholding tax at a 30% rate, or a lower rate prescribed by an
applicable tax treaty, unless the dividends are effectively connected with a
trade or business carried on by the Foreign Holder within the United States. To
determine the applicability of a tax treaty providing for a lower rate of
withholding, dividends paid to an address in a foreign country are presumed
under current Treasury regulations to be paid to a resident of that country.
Treasury regulations proposed in 1984 would, if adopted in final form, require
Foreign Holders to file certain forms to obtain the benefit of any applicable
tax treaty providing for a lower rate of withholding tax on dividends. Such
forms would have to contain the name and address of the holder and an official
statement by the competent authority of the holder's country of residence
attesting to the holder's status as a resident thereof. Dividends effectively
connected with a trade or business carried on by the Foreign Holder within the
United States generally will not be subject to withholding if the Foreign Holder
files Internal Revenue Service Form 4224 with the payor of the dividend and will
generally be subject to United States federal income tax at regular rates. In
the case of a Foreign Holder that is a corporation, such effectively connected
income may be subject to the branch profits tax which is generally imposed on a
foreign corporation on the repatriation from the United States of effectively
connected earnings and profits. The branch profits tax may not apply if the
recipient is a qualified resident of one of certain countries with which the
United States has an income tax treaty.
 
GAIN ON DISPOSITION
 
     Generally, a Foreign Holder will not be subject to United States federal
income tax on any gain realized upon the disposition of shares of Common Stock
unless (i) the Company is or has been during certain periods a "U.S. real
property holding corporation" for federal income tax purposes and, assuming that
the Common Stock is "regularly traded on an established securities market" for
tax purposes, the Foreign Holder held, directly or indirectly at any time during
the five-year period ending on the date of disposition (or such shorter period
that such shares were held), more than 5% of the Common Stock of the Company;
(ii) the gain is effectively connected with a trade or business carried on by
the Foreign Holder within the United States; (iii) the Foreign Holder is an
individual who has a tax home (as specifically defined for United States federal
income tax purposes) in the United States, holds the Common Stock as a capital
asset and is present in the United States for 183 days or more in the taxable
year of the disposition; or (iv) the Foreign Holder is subject to tax pursuant
to the provisions of United States tax law applicable to certain United States
expatriates.
 
                                       13
<PAGE>   30
 
FEDERAL ESTATE TAX
 
     Shares of Common Stock owned or treated as owned by an individual who is
not a citizen or resident of the United States at the time of death will be
includable in the individual's gross estate for United States federal estate tax
purposes, unless an applicable tax treaty provides otherwise, and may be subject
to United States federal estate tax. Estates of non-resident aliens are
generally allowed a statutory credit which has the effect of offsetting the
United States federal estate tax imposed on the first $60,000 of the taxable
estate.
 
DIVIDEND REPORTING AND BACKUP WITHHOLDING REQUIREMENTS
 
     The Company must report annually to the Internal Revenue Service and to
each Foreign Holder the amount of dividends paid to, and the tax withheld with
respect to, each Foreign Holder. These reporting requirements apply regardless
of whether withholding was reduced by an applicable tax treaty. Under the
provisions of a specific treaty or agreement, copies of these information
returns may also be made available to the tax authorities in the country in
which the Foreign Holder resides. United States backup withholding tax (which
generally is a withholding tax imposed at the rate of 31% on certain payments to
persons that fail to furnish the information required under the United States
information reporting requirements) will generally not apply to dividends paid
on the Common Stock to a Foreign Holder at an address outside the United States.
 
     The payment of the proceeds from the disposition of shares of Common Stock
to or through a United States office of a broker will be subject to information
reporting and backup withholding unless the owner certifies under penalties of
perjury its status as a Foreign Holder, or otherwise establishes an exemption.
The payment of the proceeds from the disposition of shares of Common Stock to or
through a non-U.S. office of a non-U.S. broker will generally not be subject to
backup withholding and information reporting. However, in the case of the
payment of proceeds from the disposition of shares of Common Stock through a
non-U.S. office of a broker that is a United States person or a "U.S. related
person," existing regulations require information reporting on the payment
unless the broker has documentary evidence in its files that the owner is a
Foreign Holder and the broker has no actual knowledge to the contrary. For this
purpose, a "U.S. related person" is (i) a "controlled foreign corporation" for
United States federal income tax purposes, or (ii) a foreign person 50% or more
of whose gross income from all sources for the three-year period ending with the
close of its taxable year preceding the payment is derived from activities that
are effectively connected with the conduct of a United States trade or business.
Proposed regulations contain a similar rule with respect to information
reporting by a non-U.S. office of a broker that is a United States person or a
U.S. related person. However, under the proposed regulations, such a person may
rely on documentary evidence to avoid information reporting only if the foreign
office "effects" the sale at such foreign office. The existing regulations
reserve on the question of whether reportable payments made through foreign
offices of a broker that is a United States person or a U.S. related person will
be subject to backup withholding, but proposed regulations state that backup
withholding will not apply to such payments (absent actual knowledge that the
payee is a United States person) where the foreign office "effects" the sale at
such foreign office. Any amounts withheld under the backup withholding rules
from a payment to a Foreign Holder will be refunded (or credited against that
Foreign Holder's United States federal income tax liability, if any) provided
that the required information is furnished to the Internal Revenue Service.

     Under the terms and conditions of the Underwriting Agreement, the
International Underwriters are committed to take and pay for all of the shares
offered hereby, if any are taken.
 
     The International Underwriters propose to offer the shares of Common Stock
in part directly to the public at the initial public offering price set forth on
the cover page of this Prospectus, and in part to certain securities dealers at
such price less a concession of $.55 per share. The International Underwriters
may allow, and such dealers may reallow, a concession not in excess of $.10 per
share to certain brokers and dealers. After the shares of Common Stock are
released for sale to the public, the offering price and other selling terms may
from time to time be varied by the representatives.
 
     The Company and the Selling Shareholder have entered into an underwriting
agreement (the "U.S. Underwriting Agreement") with the underwriters of the
United States Offering (the "U.S. Underwriters") providing for the concurrent
offer and sale of 11,200,000 shares of Common Stock in the United States. The
offering price and aggregate underwriting discount per share for the two
offerings are identical. The closing of the offering made hereby is a condition
to the closing of the United States offering, and vice versa. The
representatives of the U.S. Underwriters are Goldman, Sachs & Co., Merrill
Lynch, Pierce, Fenner & Smith Incorporated and Morgan Stanley & Co.
Incorporated.
 
     Pursuant to an Agreement between the U.S. and International Underwriting
Syndicates (the "Agreement Between") relating to the Offerings, each of the
International Underwriters named herein has agreed that, as a part of the
distribution of the shares offered hereby and subject to certain exceptions, it
(i) will not, directly or indirectly, offer, sell or deliver the shares offered
hereby
 
                                       15

and other shares of Common Stock (a) in the United States (including the States
and the District of Columbia), its territories, its possessions and other areas
subject to its jurisdiction (as used in this paragraph, the "United States") or
to any U.S. Persons (which term shall mean, for purposes of this paragraph: (I)
any individual who is a resident of the United States or (II) any corporation,
partnership or other entity organized in or under the laws of the United States
or any political subdivision thereof and whose office most directly involved
with the purchase is located in the United States) or (b) to any person who it
believes intends to reoffer, resell or deliver the shares in the United States
or to any U.S. Persons, and (ii) cause any dealer to whom it may sell such
shares at any concession to agree to observe a similar restriction. Each of the
U.S. Underwriters has agreed pursuant to the Agreement Between that, as a part
of the distribution of the shares offered as a part of the United States
offering, and subject to certain exceptions, it will offer, sell and deliver
shares of Common Stock, directly or indirectly, only in the United States and to
U.S. Persons.
 
     Pursuant to the Agreement Between, sales may be made between the
International Underwriters and the U.S. Underwriters of such number of shares of
Common Stock as may be mutually agreed. The price of any shares so sold will be
the initial public offering price, less an amount not greater than the selling
concession.
 
     The Selling Shareholder has granted the International Underwriters an
option exercisable for 30 days after the date of this Prospectus to purchase up
to an aggregate of 400,000 additional shares of Common Stock solely to cover
over-allotments, if any. If the International Underwriters exercise their
over-allotment option, the International Underwriters have severally agreed,
subject to certain conditions, to purchase approximately the same percentage
thereof that the number of shares to be purchased by each of them, as shown in
the foregoing table, bears to the 2,800,000 shares of Common Stock offered
hereby. The Selling Shareholder has granted the U.S. Underwriters an option
exercisable for 30 days after the date of this Prospectus to purchase up to an
aggregate of 1,600,000 additional shares of Common Stock solely to cover
over-allotments, if any. Any shares of Common Stock purchased pursuant to such
over-allotment options will be purchased at the initial public offering price
per share less the underwriting discount, as set forth on the cover page of this
Prospectus.
 
     The Selling Shareholder has agreed not to offer, sell or otherwise dispose
of any Common Stock, except for the shares of Common Stock offered in connection
with the Offerings, for a period of 180 days after the date of this Prospectus
without the prior written consent of the representatives of the Underwriters.
The Company has agreed with the Underwriters not to offer, sell, contract to
sell or otherwise dispose of any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock, except
pursuant to employee benefit plans and the Stock Purchase and Dividend
Reinvestment Plan, for a period of 90 days after the date of this Prospectus
without the prior written consent of the representatives of the Underwriters.
 
     Each International Underwriter has agreed that (i) it has not offered or
sold, and it will not offer or sell, in the United Kingdom by means of any
document any shares of Common Stock other than to persons whose ordinary
business it is to buy or sell shares or debentures, whether as principal or
agent, or in circumstances which do not constitute an offer to the public within
the meaning of the Companies Act of 1985 of Great Britain, (ii) it has complied,
and will comply, with all applicable provisions of the Financial Services Act of
1986 of Great Britain with respect to anything done by it in relation to the
Common Stock in, from or otherwise involving the United Kingdom and (iii) it has
only issued or passed on and will only issue or pass on in the United Kingdom
any document received by it in connection with the issuance of the shares of
Common Stock to a person who is of a kind described in Article 9(3) of the
Financial Services Act of 1986 (Investment Advertisements) (Exemptions) Order
1989 of Great Britain or is a person to whom the document may otherwise lawfully
be issued or passed on.
