ARTICLE I

SCOPE OF FIRST SUPPLEMENTAL INDENTURE


 


Section 1.01. Scope. This
First Supplemental Indenture constitutes a supplement to the Base Indenture and an integral part of the Indenture and shall be
read together with the Base Indenture as though all the provisions thereof are contained in one instrument. Except as expressly
amended by the First Supplemental Indenture, the terms and provisions of the Base Indenture shall remain in full force and effect.
Notwithstanding the foregoing, this First Supplemental Indenture shall only apply to the 2024 Notes.


 


ARTICLE 2

DEFINITIONS


 


Section 2.01. Definitions and Other
Provisions of General Application. For all purposes of this First Supplemental Indenture unless otherwise specified herein:


 


(a) all terms used in this First Supplemental
Indenture which are not otherwise defined herein shall have the meanings they are given in the Base Indenture;


 




    	1



    	 



    

 


(b) the provisions of general application
stated in Sections 1.01 through 1.18 of the Base Indenture shall apply to this First Supplemental Indenture, except that the words
“herein,” “hereof,” “hereto” and “hereunder” and other
words of similar import refer to this First Supplemental Indenture as a whole and not to the Base Indenture or any particular Article,
Section or other subdivision of the Base Indenture or this First Supplemental Indenture;


 


(c) Section 1.01 of the Base Indenture
is amended and supplemented, solely with respect to the 2024 Notes, by inserting the following additional defined terms in their
appropriate alphabetical positions:


 


“Issue Date” means September 30,
2014.


 


“Interest Period” means
each three-month period beginning on a scheduled Interest Payment Date.


 


“LIBOR”  means the rate
as published by Bloomberg (or other commercially available source providing quotations of such rate as selected by the Company
from time to time) at approximately 11:00 a.m., London time, two Business Days prior to the commencement of such Interest Period,
as the rate for dollar deposits in the London interbank market with a three-month maturity. If such rate is not available at such
time from such source for any reason, then the rate for that Interest Period will be determined by such alternate method as reasonably
selected by the Company.


 


“Tax Event” shall mean
the receipt by the Company of an opinion of independent tax counsel experienced in such matters to the effect that, as a result
of any amendment to, or change (including any announced prospective change) in, the laws or any regulations thereunder of the United
States or any political subdivision or taxing authority thereof or therein, or as a result of any official administrative pronouncement
or judicial decision interpreting or applying such laws or regulations, which amendment or change is effective or which pronouncement
or decision is announced on or after the date of original issuance of the Notes, there is more than an insubstantial risk that
the interest payable by the Company on the Notes is not, or within 90 days of the date of such opinion will not be, deductible
by the Company, in whole or in part, for United States federal income tax purposes.


 


“Tier 2 Capital Event”
shall mean the receipt by the Company of an opinion of independent bank regulatory counsel experienced in such matters to the effect
that, as a result of (a) any amendment to, or change (including any announced prospective change) in, the laws or any regulations

official administrative pronouncement or judicial decision interpreting or applying such laws or regulations, which amendment or
change is effective or which pronouncement or decision is announced on or after the date of original issuance of the Securities,
the Notes do not constitute, or within 90 days of the date of such opinion will not constitute, Tier 2 Capital (or its then equivalent
if the Company were subject to such capital requirement) for purposes of capital adequacy guidelines of the Board of Governors
of the Federal Reserve System (or any successor regulatory authority with jurisdiction over bank holding companies), as then in
effect and applicable to the Company.


 


(d) Section 1.01 of the Base Indenture
is amended and supplemented, solely with respect to the 2024 Notes, by replacing the corresponding defined term in the Base Indenture
with the following defined terms:

Market Street, Wilmington, Delaware 19890, Attention BNC Bancorp Administrator, or such other office, designated by the Trustee
by written notice to the Company, at which at any particular time its corporate trust business regarding the Indenture shall be
administered.


 


“Senior Indebtedness”
with respect to any series of Securities issued hereunder, shall have the meaning ascribed to such term in the Board Resolutions
or supplemental indenture establishing such series in accordance with Section 3.01 hereof, and shall include: (i) the
principal and any premium or interest for money borrowed or purchased by the Company; (ii) the principal and any premium or
interest for money borrowed or purchased by another Person and guaranteed by the Company; (iii) any deferred obligation for
the payment of the purchase price of property or assets evidenced by a note or similar instrument or agreement; (iv) an obligation

in right of payment with, the Securities or the Securities of any series; or (b) is identified as junior to, or equal in right
of payment with, the Securities or the Securities of any series in any Board Resolution or in any supplemental indenture.

BNC Bancorp, a corporation duly organized
and existing under the laws of North Carolina (herein called the “Company”, which term includes any successor Person
under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered
assigns, the principal sum of [ ] Dollars ($[ ]) on October 1, 2024 (the “Maturity Date”), and to pay interest thereon
from September 30, 2014 (the “Issue Date”) or from the most recent Interest Payment Date to which interest has
been paid or duly provided for, semi-annually in arrears on October 1 and April 1of each year through October 1, 2019, and thereafter
quarterly in arrears on January 1, April 1, July 1, and October 1 of each year through the Maturity Date or earlier Redemption
Date (each, an “Interest Payment Date”), commencing April 1, 2015, at the rate of 5.5% per annum, from the Issue
Date to but excluding October 1, 2019, and at a floating rate equal to LIBOR determined on the determination date of the applicable
Interest Period plus 359 basis points from and including October 1, 2019 to but excluding the Maturity Date, until the principal
hereof is paid or made available for payment, provided that any principal and premium, and any such installment of interest, which
is overdue shall bear interest at the rate of 5.5% per annum (to the extent that the payment of such interest shall be legally
enforceable), from the dates such amounts are due until they are paid or made available for payment, and such interest shall be
payable on demand. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided

notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date,
or 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
said Indenture.

[Reverse of Security]


 


This Security is one of a duly authorized
issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more
series under an Indenture, dated as of September 30, 2014 (herein called the “Base Indenture”, which term shall
have the meaning assigned to it in such instrument), between the Company and Wilmington Trust, National Association, as Trustee
(herein called the “Trustee”, which term includes any successor trustee under the Indenture) as supplemented
by a First Supplemental Indenture, dated as of September 30, 2014 between the Company and the Trustee (herein called the “First
Supplemental Indenture” and together with the Base Indenture, the “Indenture”), and reference is hereby
made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the
Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated
and delivered. This Security is one of the series designated on the face hereof. The Company may, without notice to or the consent
of any Holder, issue additional Securities having the same ranking, interest rate, maturity and other terms as the Securities of
this series, provided that such additional Securities are fungible for U.S. federal income tax purposes with this
Security. Any such additional Securities may be considered to be part of this series of Securities. The Company may, without notice
to or the consent of any Holder, issue or incur Senior Indebtedness or indebtedness ranking pari passu with the Securities.


 


The Indenture contains provisions for Events
of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.


 


If certain Events of Default with respect
to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due
and payable in the manner and with the effect provided in the Indenture.


 


The 2024 Notes shall only be redeemable
at the option of the Company prior to the Maturity Date as follows:


 


☐ The Company may, at
its option, redeem the 2024 Notes, in whole or in part, on any Interest Payment Date on or after October 1, 2019.


 


☐ The Company may, at
its option, redeem the 2024 Notes before the Maturity Date in whole, at any time, or in part from time to time, upon the
occurrence of a Tier 2 Capital Event or a Tax Event, or if the Company is required to register as an investment company
pursuant to the Investment Company Act of 1940 (15 U.S.C. 80a-1 et seq.).


 


Any such redemption shall be at a Redemption Price equal to
the principal amount of the 2024 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the Redemption Date.
Any such redemption by the Company prior to the Maturity Date requires the prior approval of the Board of Governors of the Federal
Reserve System.


 


So long as the 2024 Notes shall be issued
in global form, notice of redemption shall be given in electronic format to the U.S. Depository in accordance with the applicable
procedures of the U.S. Depository, not less than 30 nor more than 60 days prior to the Redemption Date, all as provided in the
First Supplemental Indenture; provided however, such notice may be sent more than 60 days prior to a redemption in connection with
a defeasance or the satisfaction and discharge of the series.


 


This Security may be redeemed in part only
in multiples of $1,000 or any integral multiples of $1,000 in excess of $1,000. In the event of redemption of this Security in
part only, a new Security or Securities for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon
the cancellation hereof.

The Indenture permits, with certain exceptions
as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of
the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected.
The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of
each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent
or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security
and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation
of such consent or waiver is made upon this Security. Notwithstanding the foregoing, without the consent of any Holder of Securities,
the Company and the Trustee may amend or supplement the Indenture or the Securities to conform to the terms of the Indenture and
the Securities to the description of the Securities in the prospectus supplement dated September 25, 2014 relating to the
offering of the Securities.


 


As provided in and subject to the provisions
of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture
or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less
than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee
to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee security or indemnity satisfactory
to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series
at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for
60 days after receipt of such notice, request and offer of security or indemnity. The foregoing shall not apply to any suit instituted
by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after
the respective due dates expressed herein.


 


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


 


As provided in the Indenture and subject
to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender
of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any
premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing,
and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.


 


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


 


No service charge shall be made for any
such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith.


 


Prior to due presentment of this Security
for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose
name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the contrary.


 


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