otherwise  expressly  provided in this Supplemental  Indenture or in the form of
Debenture set forth herein or otherwise  clearly  required by the context hereof
or thereof,  all terms used herein or in said form of Debenture that are defined

                  WHEREAS,  the Company  executed and delivered the Indenture to
         the Trustee to provide for the future  issuance  of  Securities,  to be
         issued from time to time in one or more  series as might be  determined
         by the Company under the Indenture, in an unlimited aggregate principal
         amount that may be  authenticated  and  delivered  thereunder as in the
         Indenture provided;

                  WHEREAS,  pursuant to the terms of the Indenture,  the Company
         desires to provide for the  establishment of a new series of Securities
         to  be  known  as  its  [__]%  [Senior   Debentures]  Due  [____]  (the
         "Debentures"),   the  form  and  substance  thereof,   and  the  terms,
         provisions and conditions  thereof,  to be set forth as provided in the
         Indenture and this Supplemental Indenture; and

                  WHEREAS,  the Company desires and has requested the Trustee to
         join  with  it in the  execution  and  delivery  of  this  Supplemental
         Indenture  and all  requirements  necessary  to make this  Supplemental
         Indenture a valid instrument, in accordance with its terms, and to make
         the  Debentures,  when  executed by the Company and  authenticated  and
         delivered by the Trustee,  the valid  obligations of the Company,  have
         been  performed and  fulfilled,  and the execution and delivery  hereof
         have been in all respects duly authorized.

                  NOW,   THEREFORE,   in   consideration  of  the  purchase  and
acceptance  of the  Debentures  by the holders  thereof,  and for the purpose of
setting  forth,  as provided in the  Indenture,  the form and  substance  of the
Debentures  and the  terms,  provisions  and  conditions  thereof,  the  Company
covenants and agrees with the Trustee as follows:


                                   ARTICLE ONE

                 General Terms and Conditions of the Debentures

                  SECTION 1.01. There shall be and is hereby authorized a series
of  Securities  designated  the "[___]%  [Senior  Debentures]  Due [____]",  the
aggregate  principal  amount of which shall be limited to $[___],  which  amount
shall be as set forth in any written order of the Company for the authentication
and delivery of Debentures.  Debentures may, upon execution of this Supplemental
Indenture or from time to time thereafter, be executed by the







Company and delivered to the Trustee for  authentication,  and the Trustee shall
thereupon  authenticate and deliver such Debentures to or upon the written order
of the Company,  signed by its Chairman of the Board, its President, or any Vice
President  and its  Treasurer  or an  Assistant  Treasurer,  without any further
action by the Company.  The  Debentures  shall mature and the principal  thereof
shall be due and payable together with all accrued and unpaid interest  thereon,
on  [___________],  and  shall be issued  in the form of  registered  Debentures
without coupons.

                  SECTION 1.02. (a) The Debentures shall be issued as Registered
Securities  in global  form (a "Global  Debenture")  in an  aggregate  principal
amount equal to the principal amount of the Debentures,  to be registered in the
name of The  Depository  Trust  Company,  New  York,  New York or any  successor
registered  as a clearing  agency  under the  Exchange  Act or other  applicable
statute or regulation,  as the Depository,  or its nominee, and delivered by the
Trustee to the  Depository  for  crediting to the  accounts of its  participants
pursuant to the instructions of the Company.  Payments on the Debentures  issued
as a Global Debenture will be made to the Depository.

                  (b)  Pursuant  to  the   provisions  of  Section  3.5  of  the
Indenture, the Global Debenture may be transferred, in whole but not in part, in
the manner provided in Section 3.5 of the Indenture,  only by the Depository for
such series to a nominee of the  Depository,  by a nominee of the  Depository to
the Depository or to another nominee of the Depository,  or by the Depository or
such nominee to a successor Depository selected or approved by the Company or to
a nominee of such successor Depository.

                  (c) If at any time the Depository notifies the Company that it
is unwilling or unable to continue as Depository for the Debentures or if at any
time the  Depository  for the  Debentures  shall no longer be a clearing  agency
registered  under the Exchange Act, or other  applicable  statute or regulation,
and a successor  Depository  for the  Debentures is not appointed by the Company
within 90 days after the Company  receives  such notice or becomes aware of such
condition,  as the case may be, this Section 1.02 shall no longer be  applicable
to the  Debentures  and the Company will execute and,  subject to Section 3.5 of
the  Indenture,  the  Trustee  will,  upon  receipt  of a Company  Order for the
authentication   and  delivery  of   certificated   Securities  of  like  tenor,
authenticate  and deliver  Debentures  of like tenor in  certificated  form,  in
authorized  denominations,  and in an  aggregate  principal  amount equal to the
principal amount of the Global Debenture in exchange for such Global  Debenture.
In addition,  the Company may at any time determine in its sole  discretion that
the Debentures  shall no longer be represented by a Global  Debenture,  and that
the provisions of this Section 1.02 shall no longer apply to the Debentures.  In
such  event,  the  Company  will  execute  and,  subject to  Section  3.5 of the
Indenture,  the  Trustee,  upon  receipt  of a  Company  Order  evidencing  such
determination  by  the  Company,  will  authenticate  and  deliver  certificated
Debentures in authorized denominations,  and in aggregate principal amount equal
to the  principal  amount of the Global  Debenture  in exchange  for such Global
Debenture.  Upon  exchange  of the  Global  Debenture  for  such  Debentures  in
definitive  registered form without coupons,  in authorized  denominations,  the
Global Debenture shall be canceled by the Trustee. Such Debentures in definitive
registered  form issued in exchange  for the Global  Debenture  pursuant to this
Section  1.02(c) shall be registered in such names and authorized  denominations
as the Depository, pursuant to instructions from its direct or indirect


                                  -2-





participants or otherwise, shall instruct the Trustee. The Trustee shall deliver
such  Debentures  to the  Depository  for delivery to the persons in whose names
such Debentures are so registered.
                  SECTION  1.03.  If,  pursuant  to the  provisions  of  Section
1.02(c) hereof, the Debentures are issued in certificated form, principal of and
premium, if any, and interest thereon will be payable, the transfer thereof will
be  registrable,  and Debentures  will be  exchangeable  for Debentures  bearing
identical terms and  provisions,  at the office or agency of the Company in [the
Borough of  Manhattan,  the City of New York],  in any coin or  currency  of the
United States of America that at the time of payment is legal tender for payment
of public and private debts; provided,  however, that payment of interest on any
of the  Debentures  may be made at the option of the Company by check  mailed to
the Holder thereof at such address as shall appear in the Security Register.

                  SECTION 1.04. Each Debenture will bear interest at the rate of
[___]% per annum from its  original  date of  issuance  or from the most  recent
Interest Payment Date (as defined below) to which interest has been paid or duly
provided  for until the  principal  thereof  becomes  due and  payable,  and any
overdue  principal  thereof and (to the extent that payment of such  interest is
enforceable  under  applicable law) any overdue  installment of interest thereon
will bear  interest  at the same rate per  annum,  payable in  semi-annually  in
arrears on [______] and  [________]  of each year (each,  an  "Interest  Payment
Date"),  commencing on [_____], and at Maturity to the person in whose name such
Debenture or any  Predecessor  Security  thereof is registered,  at the close of
business on the Regular Record Date for such interest  installment,  which shall
be the close of  business  on the  Business  Day 15 days  preceding  an Interest
Payment Date;  provided,  however,  that (i) if any  Debenture is  authenticated
after a Regular Record Date and before the Interest Payment Date therefor,  such
interest  installment shall be paid on the next succeeding Interest Payment Date
to the Holder  thereof on the Regular  Record Date  therefor  and (ii)  interest
payable at Maturity  shall be paid to the Person to whom  principal is paid. Any
such  interest  installment  not  punctually  paid or duly  provided  for  shall
forthwith  cease to be payable to such  Holder on such  Regular  Record  Date by
virtue of having been such Holder,  and such  defaulted  interest may be paid by
the Company, at its election,  to the person in whose name the Debenture (or one
or more Predecessor  Securities  thereof) is registered at the close of business
on a Special  Record  Date to be fixed by the  Trustee  for the  payment of such
defaulted  interest,  notice  whereof  shall  be  given  to the  Holders  of the
Debentures  not less than 10 days prior to such Special  Record Date,  or in any
other lawful manner not  inconsistent  with the  requirements  of any securities
exchange on which the Debentures  may be listed,  and upon such notice as may be
required by such exchange, all as more fully provided in the Indenture.


                                  [ARTICLE TWO

                          Redemption of the Debentures

                  SECTION  2.01.  Subject  to the  terms  of  Article  10 of the
Indenture,  the Company shall have the right to redeem the Debentures,  in whole
or in  part,  from  time  to  time,  on or  after  [_______],  at the  following
redemption prices (expressed in percentages of


                                   -3-





the principal amounts to be redeemed) during the twelve-month periods commencing
on of the years indicated:

                  Year                                        Redemption Price




plus, in each case, any accrued and unpaid interest  thereon to the date of such
redemption.  Any redemption  pursuant to this Section 2.01 will be made upon not
less than 30 nor more than 60 days' notice.  If less than all of the  Debentures
are to be  redeemed  pursuant  to this  Section  2.01,  the  Debentures  will be
redeemed  pro rata or by lot or by any other  method  utilized  by the  Trustee;
provided,  however,  that if at the time of redemption the Debentures are in the
form of a Global Debenture,  the Depository shall determine by lot the principal
amount of such Debentures held by each holder of Debentures to be redeemed.

                  SECTION  2.02.  The  Company  may  not  redeem  (or  otherwise
purchase)  less  than  all of the  Debentures  if as a  result  of such  partial
redemption  (or  purchase)  the  Debentures  would be delisted from any national
securities  exchange  on which  they are then  listed,  and in such  case if the
Company  elects to redeem (or  otherwise  purchase) any of the  Debentures,  the
Company  shall  redeem  (or  otherwise  purchase)  all of  them.  No  notice  of
redemption with respect to the Debentures may state that such  redemption  shall
be  conditional  upon the  receipt  of monies  sufficient  to pay the  principal
thereof or premium, if any, or interest thereon.]


                                  ARTICLE THREE

                                Form of Debenture

                  The Debentures and the Trustee's Certificate of Authentication
to be endorsed thereon are to be substantially in the following forms:


                           [FORM OF FACE OF DEBENTURE]

                  [[If the Debenture is to be a Global Debenture,  insert:  This
Debenture  is in global  form within the  meaning of the  Indenture  hereinafter
referred to and is registered in the name of the  Depository or a nominee of the

to the  Depository or another  nominee of the Depository or by the Depository or
any such  nominee  to a  successor  Depository  or a nominee  of such  successor
Depository.

                  Unless  this   Debenture  is   presented   by  an   authorized

the Company or its agent for registration of transfer,  exchange or payment, and

No. ________________                              CUSIP No.________________


                  PUBLIC SERVICE COMPANY OF NORTH CAROLINA,
INCORPORATED,  a corporation  duly  organized and existing under the laws of the
State of  North  Carolina  (herein  referred  to as the  "Company,"  which  term
includes any successor corporation under the Indenture referred to hereinafter),
for      value      received,      hereby      promises      to      pay      to
___________________________________, or registered assigns, the principal sum of
_____________________________  Dollars  on  [_________],  and  to  pay  interest
thereon from [______] or from the most recent  interest  payment date (each such
date,  an  "Interest  Payment  Date")  to which  interest  has been paid or duly
provided  for,  semi-annually  in arrears on [______] and [______] of each year,
commencing  [______],  and when the  principal  hereof shall have become due and
payable,  whether at  maturity,  upon call for  redemption,  by  declaration  of
acceleration or otherwise ("Maturity"), at the rate of [__]% per annum until the
principal  hereof  shall  have  become so due and  payable,  and on any  overdue
principal and premium,  if any, and (to the extent that payment of such interest
is enforceable  under applicable law) on any overdue  installment of interest at
the same rate per annum.  The amount of interest payable on any Interest Payment
Date shall be computed on the basis of a 360-day year of twelve  30-day  months.
In the event that any date on which  interest  is payable on the  Securities  of
this series is not a Business Day, then payment of interest payable on such date
will be made on the next  succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay), with the same force and
effect  as if made on such  date.  The  interest  installment  so  payable,  and
punctually  paid or duly  provided  for, on any Interest  Payment Date will,  as
provided in the  Indenture,  be paid to the person in whose name this  Debenture
(or one or more Predecessor  Securities of the same series) is registered at the
close of  business on the Regular  Record  Date for such  interest  installment,
which shall be the close of business on the  Business  Day 15 days  preceding an
Interest Payment Date; provided further,  however, that (i) if this Debenture is
authenticated  after a Regular Record Date and before the Interest  Payment Date
therefor,  such  interest  installment  shall  be  paid on the  next  succeeding
Interest  Payment Date to the  registered  holder  thereof on the Regular Record
Date therefor and (ii) interest  payable at Maturity shall be paid to the Person
to whom principal is paid. Any such interest  installment not punctually paid or
duly provided for shall forthwith cease to be payable to the registered  holders
on such Regular  Record  Date,  and may be paid to the person in whose name this
Debenture  (or  one or  more  Predecessor  Securities  of the  same  series)  is
registered at the close of business on a Special  Record Date to be fixed by the
Trustee for the payment of such  defaulted  interest,  notice  whereof  shall be
given to the registered holders of Securities


                                  -5-





of this series not less than 10 days prior to such Special  Record Date,  or may
be paid at any  time in any  other  lawful  manner  not  inconsistent  with  the
requirements  of any securities  exchange on which the Securities of this series
may be listed, and upon such notice as may be required by such exchange,  all as
more fully provided in the Indenture  hereinafter  referred to. The principal of
and  premium,  if any, and  interest on this  Debenture  shall be payable at the
office or agency of the Company  maintained  for that purpose in [the Borough of
Manhattan,  the City of New York],  in any coin or currency of the United States
of America that at the time of payment is legal tender for payment of public and
private debts; provided, however, that payment of interest on this Debenture may
be made at the option of the Company by check  mailed to the  registered  holder
hereof at such address as shall appear in the Security Register.

                  This Debenture  shall not be entitled to any benefit under the
Indenture hereinafter referred to, be valid or become obligatory for any purpose
until the Certificate of  Authentication  hereon shall have been signed by or on
behalf of the Trustee.

                  The  provisions of this Debenture are contained on the reverse
side hereof and such continued  provisions  shall for all purposes have the same
effect as though fully set forth at this place.


                                     -6-





                  IN WITNESS WHEREOF,  the Company has caused this Instrument to
be executed.

                  This [_]% [Senior  Debenture] Due [______]  (herein  sometimes
referred  to as  this  "Debenture")  is  one  of a  duly  authorized  series  of
Securities of the Company,  specified in the Indenture (as defined  below),  all
issued or to be issued in one or more series  under and pursuant to an Indenture
dated as of [________], 1996 duly executed and delivered between the Company and
FIRST UNION NATIONAL BANK OF NORTH CAROLINA,  as trustee (herein  referred to as
the "Trustee"),  as amended and supplemented  [from time to time,  including] by
the [______] Supplemental  Indenture dated as of [_________] between the Company
and the Trustee (said Indenture as so supplemented being hereinafter referred to
as the "Indenture"),  to which Indenture and all indentures supplemental thereto
reference is hereby made for a description of the rights, limitations of rights,
obligations,  duties and immunities  thereunder of the Trustee,  the Company and
the holders of the Securities of this series. By the terms of the Indenture, the
Securities are issuable in series that may vary as


                                   -7-





to amount,  date of maturity,  rate of interest and in other  respects as in the
Indenture  provided.  The  Securities  of this series are  limited in  aggregate
principal amount as specified in said Supplemental Indenture.

                  [Subject  to the terms of  Article  10 of the  Indenture,  the
Company  shall have the right to redeem  the  Securities  of this  series at the
option of the Company,  without  premium or penalty,  in whole or in part at any
time on or after [__________],  at the following redemption prices (expressed as
percentages  of the principal  amounts to be redeemed)  during the  twelve-month
periods commencing on [__________] of the years indicated:

                  Year                               Amount




plus,  in each  case,  any  accrued  but  unpaid  interest  to the  date of such
redemption. Any redemption pursuant to this paragraph will be made upon not less
than 30 nor more than 60 days'  notice.  If less than all of the  Securities  of
this  series  are to be so  redeemed,  the  Securities  of this  series  will be
redeemed  pro rata or by lot or by any other  method  utilized  by the  Trustee;
provided,  however,  that if at the time of such  redemption,  the Securities of
this  series are in global  form,  the  Depository  shall  determine  by lot the
principal  amount thereof held by each holder of Securities of this series to be
redeemed.

                  In the event of redemption  of this  Debenture in part only, a
new Debenture or Debentures for the unredeemed  portion hereof will be issued in
the name of the holder hereof upon the cancellation hereof.]

                  If an Event of Default with respect to the  Securities of this
series  shall have  occurred  and be  continuing,  the  principal of all of such
Securities  may be declared,  and upon such  declaration  shall become,  due and
payable,  in the manner,  with the effect and subject to the conditions provided
in the Indenture.

of the entire indebtedness of this Debenture upon compliance by the Company with
certain conditions set forth therein.

                  The Indenture contains  provisions  permitting the Company and
the  Trustee,  with the  consent of the  holders of not less than a majority  in
aggregate principal amount of the Securities of each series affected at the time
outstanding, as defined in the Indenture, to execute supplemental indentures for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the  provisions of the Indenture or of modifying in any manner the rights
of the  holders of  Securities;  provided,  however,  that no such  supplemental
indenture  shall,  among  other  things,  (i) change the Stated  Maturity of any
Securities of any series, or reduce the principal amount thereof,  or reduce the
rate of interest  thereon,  or reduce any premium  payable  upon the  redemption
thereof  or the amount of any  installment  of  interest  thereon,  without  the
consent of the holder of each Security so affected or (ii) reduce

the aforesaid  percentage in principal  amount of Securities that is required to
consent to any such supplemental  indenture,  without the consent of the holders
of each Security  then  outstanding  and affected  thereby.  The Indenture  also
contains provisions  permitting the holders of a majority in aggregate principal
amount of the Securities of all series at the time outstanding affected thereby,
on behalf of the holders of the  Securities  of such  series,  to waive any past
default in the  performance of any of the covenants  contained in the Indenture,
or established  pursuant to the Indenture  with respect to such series,  and its
consequences,  except  (x) a  default  in the  payment  of the  principal  of or
premium,  if any, or interest on any of the Securities of such series,  or (y) a
default in respect of any other  covenant or  provision  that cannot be modified
without  the consent of the holder of each  Security  of such  series  adversely
affected  thereby,  in each case which  default  may be waived by the  unanimous
consent of the holders  affected.  Any such consent or waiver by the  registered
holder of this Debenture  (unless revoked as provided in the Indenture) shall be
conclusive  and binding upon such holder and upon all future  holders and owners
of this  Debenture  and of any  Security of the same  series  issued in exchange
herefor or in place hereof  (whether by  registration of transfer or otherwise),
irrespective  of whether or not any  notation of such  consent or waiver is made
upon this Debenture.

                  No reference  herein to the Indenture and no provision of this
Debenture  or of the  Indenture  shall  alter or impair  the  obligation  of the
Company,  which is  absolute  and  unconditional,  to pay the  principal  of and
premium if any, and interest on this  Debenture at the time and place and at the
rate and in the money herein prescribed.

                  As   provided  in  the   Indenture   and  subject  to  certain
limitations  therein set forth, this Debenture is transferable by the registered
holder hereof on the Security  Register of the Company,  upon  surrender of this
Debenture for registration of transfer at the office or agency of the Company in
[the  Borough  of  Manhattan,  the City of New  York]  accompanied  by a written
instrument or  instruments of transfer in form  satisfactory  to the Company and
the Trustee  duly  executed by the  registered  holder  hereof or such  holder's
attorney duly authorized in writing, and thereupon one or more new Securities of
the same series of authorized denominations and for the same aggregate principal
amount will be issued to the designated  transferee or  transferees.  No service
charge will be made for any such transfer,  but the Company may require  payment
of a sum  sufficient to cover any tax or other  governmental  charge  payable in
relation thereto.

                  Prior to due presentment  for  registration of this Debenture,
the  Company,  the  Trustee and any agent of the Company or the Trustee may deem
and treat the registered  holder hereof as the absolute owner hereof (whether or
not this Debenture shall be overdue) for the purpose of receiving  payment of or
on account of the  principal  hereof and  premium,  if any,  and (subject to the
provisions of the Indenture) interest due hereon and for all other purposes, and
neither  the Company nor the Trustee nor any agent of the Company or the Trustee
shall be affected by any notice to the contrary.

                  No recourse  shall be had for the payment of the  principal of
or the  premium,  if any, or the  interest on this  Debenture,  or for any claim
based hereon,  or otherwise in respect hereof,  or based on or in respect of the
Indenture,  against any incorporator,  stockholder,  officer or director,  past,
present or future, as such, of the Company or of any


                                 -9-





predecessor  or successor  corporation,  whether by virtue of any  constitution,
statute or rule of law, or by the  enforcement  of any  assessment or penalty or
otherwise, all such liability being, by the acceptance hereof and as part of the
consideration for the issuance hereof, expressly waived and released.

                  The  Securities of this series are issuable only in registered
form without  coupons in  denominations  of $[1,000]  and any integral  multiple
thereof.  As provided in the Indenture and subject to certain limitations herein
and therein set forth,  Securities  of this series are  exchangeable  for a like
aggregate  principal  amount  of  Securities  of  this  series  of  a  different
authorized denomination, as requested by the holder surrendering the same.

                  All  terms  used in this  Debenture  that are  defined  in the
Indenture shall have the meanings assigned to them in the Indenture.
