calculation date or does not contain such yields, the rate per annum equal to
the semi-annual equivalent yield to maturity of the Comparable Treasury Issue,
calculated using a price for the Comparable Treasury Issue (expressed as a
percentage of its principal amount) equal to the Comparable Treasury Price for
such prepayment date. The Treasury Rate shall be calculated on the third
Business Day preceding the prepayment date.

Certificates are presented to the Security Registrar for transfer or reissuance
at which time such Capital Security Certificates will be canceled and a Note,
registered in the name of the holder of the Capital Security Certificate or the
transferee of the holder of such Capital Security Certificate, as the case may
be, with an aggregate principal amount equal to the aggregate liquidation amount
of the Capital Security Certificate canceled, will be executed by the Company
and delivered to the Trustee for authentication and delivery in accordance with
the Indenture and this Fourth Supplemental Indenture. On issue of such Notes,
Notes with an equivalent aggregate principal amount that were presented by the
Property Trustee to the Trustee will be deemed to have been canceled.

                  (b) A Global Note may be transferred, in whole but not in
part, only to another nominee of the Depositary, or to a successor Depositary
selected or approved by the Company or to a nominee of such successor
Depositary.

                  (c) If at any time the Depositary notifies the Company that it
is unwilling or unable to continue as Depositary or if at any time the
Depositary for such series shall no longer be registered or in good standing
under the Securities Exchange Act

                                        8





of 1934, as amended, or other applicable statute or regulation, and a successor
Depositary for such series 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, the Company will execute, and, subject to Article II of the Indenture,
the Trustee, upon written notice from the Company, will authenticate and make
available for delivery the Notes in definitive registered form without coupons,
in authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Note in exchange for such Global Note. In
addition, the Company may at any time determine that the Notes shall no longer
be represented by a Global Note. In such event the Company will execute, and
subject to Section 2.07 of the Indenture, the Trustee, upon receipt of an
Officers' Certificate evidencing such determination by the Company, will
authenticate and deliver the Notes in definitive registered form without
coupons, in authorized denominations, and in an aggregate principal amount equal
to the principal amount of the Global Note in exchange for such Global Note.
Upon the exchange of the Global Note for such Notes in definitive registered
form without coupons, in authorized denominations, the Global Note shall be
canceled by the Trustee. Such Notes in definitive registered form issued in
exchange for the Global Note shall be registered in such names and in such
authorized denominations as the Depositary, pursuant to instructions from its
direct or indirect participants or otherwise, shall instruct the Trustee. The
Trustee shall deliver such Securities to the Depositary for delivery to the
Persons in whose names such Securities are so registered.

SECTION 2.5                Interest.

                  (a) Each Note will bear interest at the rate of 8 1/4% per
annum (the "Coupon Rate") from April 22, 1997 until the principal thereof
becomes due and payable, and on any overdue principal and (to the extent that
payment of such interest is enforceable under applicable law) on any overdue
installment of interest at the Coupon Rate, compounded semi-annually, payable
(subject to the provisions of Article IV) semi-annually in arrears on April 15
and October 15 of each year (each, an "Interest Payment Date," commencing on
October 15, 1997), to the Person in whose name such Note or any predecessor Note
is registered, at the close of business on the regular record date for such
interest installment, which, in respect of any Notes of which the Property
Trustee is the Holder of a Global Note, shall be the close of business on the
Business Day next preceding that Interest Payment Date. Notwithstanding the
foregoing sentence, if the Capital Securities are no longer in Book-Entry only
form, the relevant record dates shall be April 1 and October 1 prior to the
regular Interest Payment Date.


                                        9





                  (b) The amount of interest payable for any period will be
computed on the basis of a 360-day year of twelve 30-day months. Except as
provided in the following sentence, the amount of interest payable for any
period shorter than a full semi-annual period for which interest is computed,
will be computed on the basis of the actual number of days elapsed in such a
30-day period. In the event that any date on which interest is payable on the
Notes is not a Business Day, then payment of interest payable on such date will
be made on the next succeeding day which is a Business Day (and without any
interest or other payment in respect of any such delay), except that, if such
Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding Business Day, in each case with the same force and
effect as if made on such date.

                  (c) If, at any time while the Property Trustee is the Holder
of any Notes, the Trust or the Property Trustee is required to pay any taxes,
duties, assessments or governmental charges of whatever nature (other than
withholding taxes) imposed by the United States, or any other domestic taxing
authority, then, in any case, the Company will pay as additional interest
("Additional Interest") on the Notes held by the Property Trustee, such
additional amounts as shall be required so that the net amounts received and
retained by the Trust and the Property Trustee after paying such taxes, duties,
assessments or other governmental charges will be equal to the amounts the Trust
and the Property Trustee would have received had no such taxes, duties,
assessments or other government charges been imposed.


                                   ARTICLE III
                             PREPAYMENT OF THE NOTES

SECTION 3.1                Special Event Prepayment.

                  If a Special Event has occurred and is continuing prior to
April 15, 2007 Company shall have the right upon not less than 30 days nor more
than 60 days notice to the Holders of the Notes to prepay the Notes, in whole
but not in part, for cash within 90 days following the occurrence of such
Special Event (the "90 Day Period") at a prepayment price equal to the Special
Event Prepayment Price. The Special Event Prepayment Price shall be paid prior
to 12:00 noon, New York time, on the date of such repayment or such earlier time
as the Company determines, provided that the Company shall deposit with the
Trustee an amount sufficient to pay the Special Event Prepayment Price by 10:00
a.m., New York time, on the date such Special Event Prepayment Price is to be
paid.


                                       10





SECTION 3.2                Optional Prepayment by Company.

                  (a) Subject to the provisions of Section 3.2(b) and to the
provisions of Article Fourteen of the Indenture, the Company shall have the
right to prepay the Notes, in whole or in part, at any time and from time to
time, on or after April 15, 2007, at a redemption price equal to the Optional
Prepayment Price. Any prepayment pursuant to this paragraph will be made upon
not less than 30 days nor more than 60 days notice to the Holder of the Notes,
at the Optional Prepayment Price. If the Notes are only partially prepaid
pursuant to this Section 3.2, the Notes will be prepaid pro rata or by lot or by
any other method utilized by the Trustee; provided, that if at the time of
prepayment the Notes are registered as a Global Note, the Depositary shall
determine, in accordance with its procedures, the principal amount of such Notes
held by each Holder of Note to be prepaid. The Optional Prepayment Price shall
be paid prior to 12:00 noon, New York time, on the date of such prepayment or at
such earlier time as the Company determines provided that the Company shall
deposit with the Trustee an amount sufficient to pay the Optional Prepayment
Price by 10:00 a.m., New York time, on the date such Optional Prepayment Price
is to be paid.

                  (b) If a partial prepayment of the Notes would result in the
delisting of the Capital Securities issued by the Trust from any national
securities exchange or other organization on which the Capital Securities are
then listed, the Company shall not be permitted to effect such partial
prepayment and may only prepay the Notes in whole.

SECTION 3.3                No Sinking Fund.

                  The Notes are not entitled to the benefit of any sinking fund.


                                   ARTICLE IV
                      EXTENSION OF INTEREST PAYMENT PERIOD

SECTION 4.1                Extension of Interest Payment Period.

                  The Company shall have the right, at any time and from time to
time during the term of the Notes, to defer payments of interest by extending
the interest payment period of such Notes for a period not exceeding 10
consecutive semi-annual periods (the "Extended Interest Payment Period"), during
which Extended Interest Payment Period no interest shall be due and payable;
provided that no Extended Interest Payment Period may extend beyond the Maturity
Date. To the extent permitted by applicable law, interest, the payment of which
has been deferred because of the extension of the interest payment period
pursuant to this

                                       11





Section 4.1, will bear interest thereon at the Coupon Rate compounded
semi-annually for each semi-annual period of the Extended Interest Payment
Period ("Compounded Interest"). At the end of the Extended Interest Payment
Period, the Company shall pay all interest accrued and unpaid on the Notes,
including any Additional Interest and Compounded Interest (together, "Deferred
Interest") that shall be payable to the Holders of the Notes in whose names the
Notes are registered in the Security Register on the first record date after the
end of the Extended Interest Payment Period. Before the termination of any
Extended Interest Payment Period, the Company may further extend such period,
provided that such period together with all such further extensions thereof
shall not exceed 10 consecutive semi-annual periods, or extend beyond the
Maturity Date of the Notes. Upon the termination of any Extended Interest
Payment Period and upon the payment of all Deferred Interest then due, the
Company may commence a new Extended Interest Payment Period, subject to the
foregoing requirements. No interest shall be due and payable during an Extended
Interest Payment Period, except at the end thereof, but the Company may prepay
at any time all or any portion of the interest accrued during an Extended
Interest Payment Period.

SECTION 4.2                Notice of Extension.

                  (a) If the Property Trustee is the only registered Holder of
the Notes at the time the Company selects an Extended Interest Payment Period,
the Company shall give written notice to the Regular Trustees, the Property
Trustee and the Trustee of its selection of such Extended Interest Payment
Period at least one Business Day before the earlier of (i) the next succeeding
date on which Distributions on the Trust Securities issued by the Trust are
payable, or (ii) the date on which the Trust is required to give notice of the
record date, or the date on which such Distributions are payable, to any
applicable self-regulatory organization or to holders of the Capital Securities
issued by the Trust, but in any event at least one Business Day before such
record date.

                  (b) If the Property Trustee is not the only Holder of the
Notes at the time the Company selects an Extended Interest Payment Period, the
Company shall give the Holders of the Notes and the Trustee written notice of
its selection of such Extended Interest Payment Period at least 10 Business Days
before the earlier of (i) the next succeeding Interest Payment Date, or (ii) the
date the Company is required to give notice of the record or payment date of
such interest payment to any applicable self-regulatory organization or to
Holders of the Notes.

                  (c)      The semi-annual period in which any notice is
given pursuant to paragraphs (a) or (b) of this Section 4.2 shall

                                       12





be counted as one of the 10 semi-annual periods permitted in the
maximum Extended Interest Payment Period permitted under
Section 4.1.

SECTION 4.3                Limitation of Transactions.

                  If (i) the Company shall exercise its right to defer payment
of interest as provided in Section 4.1 and such Extended Interest Payment Period
is continuing or (ii) there shall have occurred and be continuing any Event of
Default or Nonpayment, as defined in the Indenture, then (a) the Company shall
not declare or pay any dividend on, make any distributions with respect to, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
its capital stock (other than (i) purchases or acquisitions of shares of its
common stock in connection with the satisfaction by the Company of its
obligations under any employee benefit plans, (ii) as a result of a
reclassification of its capital stock for another class or series of its capital
stock or (iii) the purchase of fractional interests in shares of its capital
stock pursuant to an acquisition or the conversion or exchange provisions of
such capital stock or security being converted or exchanged) or make any
guarantee payment with respect thereto and (b) the Company shall not make any
payment of interest, principal or premium, if any, on or repay, repurchase or
redeem any debt securities (including guarantees)issued by the Company which
rank pari passu with or junior to the Notes.

                  If the Notes are to be issued as a Global Note in connection

                  NATIONSBANK CORPORATION, a North Carolina corporation (the
"Company", which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay to
______________ or registered assigns, the principal sum of _____________ Dollars
($___________) on April 15, 2027 (the "Maturity Date"), and to pay interest on
said principal sum from April 22, 1997, 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 (subject to deferral as set forth
herein) in arrears on April 15 and October 15 of each year commencing October
15, 1997, at the rate of 8 1/4% per annum until the principal hereof shall have
become due and payable, and on any overdue principal and premium, if any, and
(without duplication 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 compounded semi-annually. 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
this Note 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), except that, if such
Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding Business Day, in each case 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 Note (or one
or more Predecessor Securities, as defined in the Indenture) 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 next preceding such
Interest Payment Date. [IF PURSUANT TO THE PROVISIONS OF THE INDENTURE THE NOTES
ARE NO LONGER REPRESENTED BY A GLOBAL NOTE -- which shall be the close of

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 Note (or one or more Predecessor Securities) 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 this series of Notes 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 Notes may be listed, and
upon such notice as may be required by such exchange, all as more fully provided
in the Indenture. The principal of (and premium, if any) and the interest on
this Note shall be payable at the office or agency of

                                       16





the Trustee maintained for that purpose 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 may be
made at the option of the Company by check mailed to the registered Holder at
such address as shall appear in the Security Register. Notwithstanding the
foregoing, so long as the Holder of this Note is the Property Trustee, the
payment of the principal of (and premium, if any) and interest on this Note will
be made at such place and to such account as may be designated by the Property
Trustee.

                  The indebtedness evidenced by this Note is, to the extent
provided in the Indenture, subordinate and junior in right of payment to the
prior payment in full of all Senior Obligations (as defined in the Indenture)
and this Note is issued subject to the provisions of the Indenture with respect
thereto. Each Holder of this Note, by accepting the same, (a) agrees to and
shall be bound by such provisions, (b) authorizes and directs the Trustee on his
or her behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination so provided and (c) appoints the
Trustee his or her attorney-in-fact for any and all such purposes. Each Holder
hereof, by his or her acceptance hereof, hereby waives all notice of the
acceptance of the subordination provisions contained herein and in the Indenture
by each holder of Senior Obligations, whether now outstanding or hereafter
incurred, and waives reliance by each such holder upon said provisions.

                  This Note 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.

hereof and such continued provisions shall for all purposes have the same effect
as though fully set forth at this place.

                            (FORM OF REVERSE OF NOTE)

                  This Note is one of a duly authorized series of Notes of the
Company (herein sometimes referred to as the "Notes"), specified in the
Indenture, all issued or to be issued in one or more series under and pursuant
to an Indenture dated as of November 27, 1996, duly executed and delivered
between the Company and The Bank of New York, as Trustee (the "Trustee"), as
supplemented by the Fourth Supplemental Indenture dated as of April 22, 1997
(the "Fourth Supplemental Indenture"), between the Company and the Trustee (the
Indenture as so supplemented, 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 Notes. By the terms of the
Indenture, the Notes are issuable in series that may vary as to amount, date of
maturity, rate of interest and in other respects as provided in the Indenture.
This series of Notes is limited in aggregate principal amount as specified in
the Fourth Supplemental Indenture.

                  Because of the occurrence and continuation of a Special Event,
as defined in the Indenture, in certain circumstances, this Note may become due
and payable at a prepayment price equal to the greater of (i) 100% of the
principal amount of the Notes or (ii) as determined by a Quotation Agent, the
sum of (a) the present value of the principal amount and premium that would be
payable as part of the Optional Prepayment Price with respect to an Optional
Prepayment of any such Notes on April 15, 2007, and (b) the present values of
scheduled payments of interest from the prepayment date to April 15, 2007, in
each case discounted to the prepayment date on a semi-annual basis (assuming a
360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate,
plus, in the case of either (i) or (ii), accrued interest on the Notes up to but
excluding the date of prepayment(the "Special Event Prepayment Price"). The
Special Event Prepayment Price shall be paid prior to 12:00 noon, New York time,
on the date of such prepayment or at such earlier time as the Company
determines. The Company shall have the right to prepay this Note at the option
of the Company, in whole or in part at any time on or after April 15, 2007 (an
"Optional Prepayment"), or at any time in certain circumstances upon the
occurrence of a Special Event, at a redemption price equal to the percentage of
the outstanding principal amount of the Junior Subordinated Notes specified
below, plus, in each case, accrued interest thereon to the date of prepayment:

                           April 15, 2007 to April 14, 2008: 103.85%
                           April 15, 2008 to April 14, 2009: 103.46%
                           April 15, 2009 to April 14, 2010: 103.08%
                           April 15, 2010 to April 14, 2011: 102.69%

(the "Optional Prepayment Price"). Any prepayment pursuant to this paragraph
will be made upon not less than 30 days nor more than 60 days notice, at the
Optional Prepayment Price. If the Notes are only partially prepaid by the
Company pursuant to an Optional Prepayment, the Notes will be prepaid pro rata
or by lot or by any other method utilized by the Trustee; provided that if, at
the time of prepayment, the Notes are registered as a Global Note, the
Depositary shall determine the principal amount of such Notes held by each Note
holder to be prepaid in accordance with its procedures.

                  In the event of prepayment of this Note in part only, a new
Note or Notes of this series for the unrepaid portion hereof will be issued in
the name of the Holder hereof upon the cancellation hereof.

                  In case an Event of Default, as defined in the Indenture,
shall have occurred and be continuing, the principal of all of the Notes 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.

                  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 Notes 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 any supplemental indenture or of
modifying in any manner the rights of the Holders of the Notes; provided,
however, that no such supplemental indenture shall (i) extend the fixed maturity
of any Notes of any series, or reduce the principal amount thereof, or reduce
the rate or extend the time of payment of interest thereon, or reduce any
premium payable upon the redemption thereof, without the consent of the Holder
of each Note so affected, or (ii) reduce the aforesaid percentage of Notes, the
Holders of which are required to consent to any such supplemental indenture,
without the consent of the Holders of each Note then outstanding and affected
thereby. The Indenture also contains provisions permitting the Holders of a
majority in aggregate principal amount of the Notes of any series at the time

                                       21





outstanding affected thereby, on behalf of all of the Holders of the Notes 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. Any such consent or waiver by
the registered Holder of this Note (unless revoked as provided in the Indenture)
shall be conclusive and binding upon such Holder and upon all future Holders and
owners of this Note and of any Note 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 Note.

                  No reference herein to the Indenture and no provision of this
Note 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 Note at the time and place and at the rate and in the
money herein prescribed.

                  The Company shall have the right at any time during the term
of the Notes and from time to time to defer payment of interest by extending the
interest payment period of such Notes for a period not exceeding 10 consecutive
semi-annual periods (an "Extended Interest Payment Period"), at the end of which
period the Company shall pay all interest then accrued and unpaid (together with
interest thereon at the rate specified for the Notes to the extent that payment
of such interest is enforceable under applicable law); provided that no Extended
Interest Payment Period may last beyond the Maturity Date of the Notes. Before
the termination of any such Extended Interest Payment Period, the Company may
further extend such Extended Interest Payment Period, provided that such
Extended Interest Payment Period together with all such further extensions
thereof shall not exceed 10 consecutive semi-annual periods or extend the
Maturity Date of the Notes. At the termination of any such Extended Interest
Payment Period and upon the payment of all accrued and unpaid interest and any
additional amounts then due, the Company may commence a new Extended Interest
Payment Period, subject to the requirements contained in this paragraph.

                  As provided in the Indenture and subject to certain
limitations therein set forth, this Note is transferable by the registered
Holder hereof on the Security Register of the Company, upon surrender of this
Note for registration of transfer at the office or agency of the Trustee in the
City and State of New York accompanied by a written instrument or instruments of
transfer in form satisfactory to the Company or the Trustee duly executed by the
registered Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Notes of authorized denominations and for the same
aggregate principal amount and

                                       22





series 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 transfer of this
Note, the Company, the Trustee, any paying agent and the Security Registrar may
deem and treat the registered holder hereof as the absolute owner hereof
(whether or not this Note shall be overdue and notwithstanding any notice of
ownership or writing hereon made by anyone other than the Security Registrar)
for the purpose of receiving payment of or on account of the principal hereof
and premium, if any, and interest due hereon and for all other purposes, and
neither the Company nor the Trustee nor any paying agent nor any Security
Registrar shall be affected by any notice to the contrary.

                  No recourse shall be had for the payment of the principal of
or the interest on this Note, 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 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.

                  This Global Note is exchangeable for Notes in definitive form
only under certain limited circumstances set forth in the Indenture. Notes of
this series so issued 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, Notes
of this series so issued are exchangeable for a like aggregate principal amount
of Notes of this series of a different authorized denomination, as requested by
the Holder surrendering the same.

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

                  THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN
THE INDENTURE AND THE NOTES WITHOUT REGARD TO CONFLICT OF LAW
PROVISIONS THEREOF.
