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
in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest, which shall be the September 15 or March 15 (whether or not a Business

such Interest Payment Date. “Business Day” means any day that is not a Saturday or Sunday, and that is not a Legal
Holiday or a day on which banking institutions in the City of New York are authorized or obligated by law, regulation or executive
order to close. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder
on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities)
is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Company,
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.

in global form, the Company shall make, through the Paying Agent, all payments of principal and interest on the 2024 Notes in immediately
available funds to the Depository or its nominee, in accordance with applicable procedures of the Depository. If the 2024 Notes

the office or agency of the Company maintained for that purpose in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts; provided, however, that at
the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register.

[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.
