		(1)	a statement that each individual signing such certificate or opinion has read such covenant or
condition and the definitions herein relating thereto;

 

		(2)	a brief statement as to the nature and scope of the examination or investigation upon which the
statements or opinions contained in such certificate or opinion are based;

 

		(3)	a statement that, in the opinion of each such individual, he or she has made such examination or
investigation as is necessary to enable him or her to express an informed opinion as to whether or not such covenant or condition

Section
103.       Form of Documents Delivered to Trustee

 

In any case where several
matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters
be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document,
but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other
matters, and any such Person may certify or give an opinion as to such matters in one or several documents. Where any Person is
required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments
under this Indenture, they may, but need not, be consolidated and form one instrument.

 

Any certificate or
opinion of an officer of or counsel for the Company may be based, insofar as it relates to legal matters, upon a certificate or
opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that
the certificate or opinion or representations with respect to the matters upon which his or her certificate or opinion is based
are erroneous. Any such certificate or opinion of counsel may be based, insofar as it relates to factual matters, upon a certificate
or opinion of, or representations by, an officer or officers of the Company, stating that the information with respect to such
factual matters is in the possession of the Company, unless such counsel knows that the certificate or opinion or representations
with respect to such matters are erroneous.

 

    8

     

    

 

Any certificate or
opinion of an officer of or counsel for the Company may be delivered electronically.

 

Whenever, subsequent
to the receipt by the Trustee of any Board Resolution, Officers’ Certificate, Opinion of Counsel or other document or instrument,
a clerical, typographical or other inadvertent or unintentional error or omission shall be discovered therein, a new document or
instrument may be substituted therefor in corrected form with the same force and effect as if originally received in the corrected
form and, irrespective of the date or dates of the actual execution and/or delivery thereof, such substitute document or instrument
shall be deemed to have been executed and/or delivered as of the date or dates required with respect to the document or instrument
for which it is substituted. Without limiting the generality of the foregoing, any Securities issued under the authority of such
defective document or instrument shall nevertheless be the valid obligations of the Company entitled to the benefits of this Indenture
equally and ratably with all other Outstanding Securities.

 

Section
104.      Acts of Holders; Record Dates

 

Any request, demand,
authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed (either physically
or by means of a facsimile or an electronic transmission, provided that such electronic transmission is transmitted through
the facilities of a Depositary) by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise
expressly provided, such action shall become effective when such instrument or instruments are delivered (either physically or
by means of a facsimile or an electronic transmission, provided that such electronic transmission is transmitted through
the facilities of a Depositary) to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments
(and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the
Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent
shall be sufficient for any purpose of this Indenture and (subject to Section 315 of the Trust Indenture Act) conclusive in favor
of the Trustee and the Company, if made in the manner provided in this Section.

 

Without limiting the
generality of the foregoing, a Holder, including a Depositary that is a Holder of a Global Security, may make, give or take, by
a proxy or proxies, duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other
action provided in this Indenture to be made, given or taken by Holders, and a Depositary that is a Holder of a Global Security
may provide its proxy or proxies to the beneficial owners of interests in any such Global Security. With respect to any Global
Security the Depositary for which is The Depository Trust Company (“DTC”), any consent or other action given,
made or taken by an “agent member” of DTC by electronic means in accordance with the Automated Tender Offer Procedures
system or other applicable procedures of, and pursuant to authorization by, DTC shall be deemed to constitute the “Act”
of the Holder of such Global Security, and such Act shall be deemed to have been delivered to the Company and the Trustee upon
the delivery by DTC of an “agent’s message” or other notice of such consent or other action having been so given,
made or taken in accordance with the applicable procedures of DTC.

 

    9

     

    

 

The fact and date of
the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or
by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual
signing such instrument or writing acknowledged to such Person the execution thereof. Where such execution is by a signer acting
in a capacity other than the signer’s individual capacity, such certificate or affidavit shall also constitute sufficient
proof of the signer’s authority. The fact and date of the execution of any such instrument or writing or the authority of
the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

 

The ownership, principal
amount and serial numbers of Securities held by any Person, and the date of commencement of such Person’s holding the same,
shall be proved by the Security Register.

 

Any request, demand,
authorization, direction, notice, consent, waiver or other action of the Holder of any Security shall bind every future Holder
of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor
or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon,
whether or not notation of such action is made upon such Security.

 

Without limiting the
foregoing, a Holder entitled hereunder to give or take any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do
so pursuant to such appointment with regard to all or any different part of such principal amount.

 

The Company may set
any day as the record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give
or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture
to be given or taken by Holders of Securities of such series, but the Company shall have no obligation to do so. With regard to
any record date set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date
(or their duly appointed agents), and only such Persons, shall be entitled to give or take the relevant action, whether or not
such Holders remain Holders after such record date.

 

Section
105.      Notices, Etc., to Trustee and Company

 

Any request, demand,
authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with

 

		(1)	the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if
made in writing and actually received by the Trustee at its office at 950 17th Street, 5th Floor, Denver, Colorado 80202, or at
any other address previously furnished in writing by the Trustee, or

 

		(2)	the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless
otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company, addressed to it at
401 North 31st Street, Billings, Montana 59116, Attention: Chief Financial Officer, or at any other address previously furnished
in writing to the Trustee by the Company.

Section
106.      Notice to Holders; Waiver

 

Where this Indenture
provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid (if international mail, by air mail), to each Holder affected by such event,
at its address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest
date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure
to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice
with respect to other Holders. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed to have
been received by such Holder, whether or not such Holder actually receives such notice.

 

Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

 

In case of the suspension
of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification
as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

 

Where this Indenture
provides for notice or other communication with respect to any event to a Holder of a Global Security, such notice or other communication
shall be sufficiently given if given to the Depositary for such Security (or its designee), pursuant to its applicable procedures,
not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice
or other communication.

 

Section
107.      Conflict with Trust Indenture Act

 

If any provision hereof
limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a part of and
govern this Indenture, the provision of the Trust Indenture Act shall control. If any provision of this Indenture modifies or excludes
any provision of the Trust Indenture Act that may be so modified or excluded, the provision of the Trust Indenture Act shall be
deemed to apply to this Indenture as so modified or excluded, as the case may be. Whenever this Indenture refers to a provision
of the Trust Indenture Act, the provision is incorporated by reference in and made a part of this Indenture.

 

Section

Section
110.      Separability Clause

 

In case any provision
in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

111.      Benefits of Indenture

 

Nothing in this Indenture
or in the Securities, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder,
the holders of any designated senior debt and the Holders, any benefit or any legal or equitable right, remedy or claim under this
Indenture.

 

Section
112.     Governing Law

 

This Indenture and
the Securities shall be governed by and construed in accordance with the law of the state of New York without reference to its
principles of conflict of laws (other than Section 5-1401 of the General Obligations Law).

 

Section
113.       Legal Holidays

 

In any case where any
Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the Securities (other than a provision of the Securities of any
series which specifically states that such provision shall apply in lieu of this Section)) payment of interest or principal (and
premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity, provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date
or Stated Maturity, as the case may be.

 

Section
114.       Language of Notices, Etc.

authorization, direction, notice, consent, waiver or Act required or permitted under this Indenture shall be in the English language,

Section
115.      Interest Limitation

 

It is the intention
of the Company to conform strictly to all applicable usury laws and any subsequent revisions, repeals or judicial interpretations
thereof. Accordingly, if the transactions contemplated hereby would be usurious under any applicable law then, in that event, notwithstanding
anything to the contrary in the Securities or this Indenture, it is agreed as follows: (i) the aggregate of all consideration which
constitutes interest under applicable law with respect to a Security shall under no circumstances exceed the maximum amount allowed
by applicable law, and any excess shall be credited to the principal amount of such Security (or, if the principal amount of such
Security shall have been paid in full, refunded to the Company), to the extent permitted by applicable law; and (ii) in the event
that the maturity of any Security is accelerated or in the event of any redemption of such Security, then such consideration that
constitutes interest under applicable law may never include more than the maximum amount allowed by applicable law, and any excess
shall be credited to the principal amount of such Security (or, if the principal amount of such Security shall be paid in full,
refunded to the Company), to the extent permitted by applicable law. All calculations made to compute the rate of interest with
respect to a Security for the purpose of determining whether such rate exceeds the maximum amount allowed by applicable law shall
be made, to the extent permitted by such applicable law, by allocating and spreading during the period of the full stated term
of such Security all interest any time contracted for, taken, reserved, charged or received by such Holder or by the Trustee on
behalf of any such Holder in connection therewith so that the amount or rate of interest charged for any and all periods of time
during the term of the Security does not exceed the maximum amount or rate of interest allowed to be charged by law during the
relevant period of time. Notwithstanding any of the foregoing, if at any time applicable laws shall be changed so as to permit
a higher rate or amount of interest to be charged than that permitted prior to such change, then unless prohibited by law, references
in this Indenture or any Security to “applicable law” when used in the context of determining the maximum interest
or rate of interest that can be charged shall be deemed to refer to such applicable law as so amended to allow the greater amount
or rate of interest.

 

The right to accelerate
maturity of any Security does not include the right to accelerate any interest which has not otherwise accrued to the date of such
acceleration, provided, however, that the foregoing shall not prohibit the continuing accrual after acceleration
of interest in accordance with the terms of the Indenture and such Security.

 

Section
116.     No Personal Liability of Officers, Directors, Employees or Shareholders

 

Obligations of the
Company under this Indenture and the Securities hereunder are payable only out of cash flow and assets of the Company. The Trustee,
and each Holder of a Security by its acceptance thereof, will be deemed to have agreed in this Indenture that no director, officer,
employee, or shareholder, as such, of the Company, the Trustee, or any Affiliate of any of the foregoing entities shall have any
personal liability in respect of the obligations of the Company under this Indenture or such Securities by reason of his, her or
its status. The agreements set forth in this Section are part of the consideration for the issuance of the Securities.

 

Section
117.      Applicability of Depositary

 

Notwithstanding any
other provision of this Indenture, so long as a series of Securities is a Global Security, the parties hereto will be bound at
all times by the applicable procedures of the Depositary with respect to such series, and the Trustee shall not be deemed to have
knowledge, at any time, of the identity of the beneficial owners of the Securities unless it shall have been provided with a list
of the beneficial owners by the Depository as of such time.

Section
118.      Duplicate Originals; Electronic Delivery

 

The parties may execute
any number of counterparts of this Indenture and of any indenture supplemental hereto. Each executed copy hereof or thereof shall
be an original, but all of such copies together shall represent one and the same instrument. The exchange of copies hereof or thereof
and of signature pages hereto or thereto by facsimile or electronic format (e.g., .pdf or .tif) transmission shall constitute effective
execution and delivery as to the respective parties hereto or thereto, and may be used in lieu of the original such document for
all purposes. Signatures of the parties hereto or thereto transmitted by facsimile or electronic format (e.g., .pdf or .tif) shall
be deemed to be original signatures for all purposes.

from [_____], or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually
on [_____] and [_____] in each year, commencing [_____], at the rate of [_____]% per annum, until the principal hereof is paid
or made available for payment [if applicable, insert-, and at the rate of [_____] % per annum on any overdue principal and premium
and on any overdue installment of interest]. [If applicable, insert-The amount of interest payable for any period shall be computed
on the basis of twelve 30-day months and a 360-day year. The amount of interest payable for any partial period shall be computed
on the basis of a 360-day year of twelve 30-day months and the days elapsed in any partial month. In the event that any date on
which interest is payable on this Security is not a Business Day, then a payment of the 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) with
the same force and effect as if made on the date the payment was originally payable. A “Business Day” shall mean, when
used with respect to any Place of Payment, each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking
institutions in that Place of Payment are authorized or obligated by law, executive order or regulation to close.] The interest
so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid

Regular Record Date for such interest, which shall be the [_____] or [_____] (whether or not a Business Day), as the case may be,
next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for shall 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 Trustee, notice of which 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 or automated quotation system on which the Securities of this series may be listed or traded, and upon
such notice as may be required by such exchange or automated quotation system, all as more fully provided in such Indenture].

in payment of principal upon acceleration, upon redemption or at Stated Maturity and in such case the overdue principal of this
Security shall bear interest at the rate of [_____]% per annum, which shall accrue from the date of such default in payment to
the date payment of such principal has been made or duly provided for. Interest on any overdue principal shall be payable on demand.
Any such interest on any overdue principal that is not so paid on demand shall bear interest at the rate of [_____]% per annum,
which shall accrue from the date of such demand for payment to the date payment of such interest has been made or duly provided
for, and such interest shall also be payable on demand.]

If Securities of a

Section 301(9) and Section 302, any Global Security shall represent such of the Outstanding Securities of such series as shall
be specified therein and may provide that it shall represent the aggregate amount of Outstanding Securities from time to time endorsed
thereon and that the aggregate amount of Outstanding Securities represented thereby may from time to time be reduced or increased,
as the case may be, to reflect exchanges. Any endorsement of a Global Security to reflect the amount, or any reduction or increase
in the amount, of Outstanding Securities represented thereby shall be made in such manner and upon instructions given by such Person
or Persons as shall be specified therein or in a Company Order. Subject to the provisions of Sections 303, 304 and 305, the Trustee
shall deliver and redeliver any Global Security in the manner and upon instructions given by the Person or Persons specified therein

Global Security shall be in a Company Order (which need not comply with Section 102 and need not be accompanied by an Opinion of
Counsel).

 

The provisions of the
last sentence of Section 303 shall apply to any Security represented by a Global Security if such Security was never issued and
sold by the Company and the Company delivers to the Trustee the Global Security together with a Company Order (which need not comply

the Board Resolution or Officers’ Certificate referred to above or in any such indenture supplemental hereto.

 

Any such Board Resolution
or Officers’ Certificate referred to above with respect to Securities of any series filed with the Trustee on or before the
initial issuance of the Securities of such series shall be incorporated herein by reference with respect to Securities of such
series and shall thereafter be deemed to be a part of the Indenture for all purposes relating to Securities of such series as fully
as if such Board Resolution or Officers’ Certificate were set forth herein in full.

 

All Securities of any
one series need not be issued at the same time and, unless otherwise provided, a series may be reopened, without the consent of
the Holders, for increases in the aggregate principal amount of such series of Securities and issuances of additional Securities
of such series or for the establishment of additional terms with respect to the Securities of such series.

 

    25

     

    

 

If any of the terms
of the series are established by action taken by or pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by an authorized officer or other authorized Person on behalf of the Company and delivered to the Trustee at
or prior to the delivery of the Officers’ Certificate or Company Order setting forth, or providing the manner for determining,
the terms of the series.

 

With respect to Securities
of a series subject to a Periodic Offering, such Board Resolution or Officers’ Certificate may provide general terms for
Securities of such series and provide either that the specific terms of particular Securities of such series shall be specified
in a Company Order, or that such terms shall be determined by the Company, or one or more of the Company’s agents designated
in an Officers’ Certificate, in accordance with a Company Order.

 

Section
302.      Denominations

 

The Securities of each
series shall be issuable only in registered form without coupons in such denominations as shall be specified as contemplated by
Section 301. In the absence of any such specified denomination with respect to the Securities of any series, the Securities of
such series shall be issuable in minimum denominations of $1,000 and any integral multiple in excess thereof.

 

Section
303.      Execution, Authentication, Delivery and Dating

the President, a Vice President, the Chief Financial Officer, the Chief Accounting Officer, the Controller, the Treasurer, an Assistant
Treasurer, the Secretary or an Assistant Secretary of the Company and need not be attested. The signature of any of these officers
on the Securities may be manual or facsimile.

 

Securities bearing
the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery
of such Securities or did not hold such offices at the date of such Securities.

 

    26

     

    

 

At any time and from
time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities,
and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities; provided, however,
that in the case of Securities offered in a Periodic Offering, the Trustee shall authenticate and deliver such Securities from
time to time in accordance with such other procedures (including the receipt by the Trustee of oral or electronic instructions
from the Company or its duly authorized agents, thereafter promptly confirmed in writing) acceptable to the Trustee as may be specified
by or pursuant to a Company Order delivered to the Trustee prior to the time of the first authentication of Securities of such
series. If the form or terms of the Securities of the series have been established in or pursuant to one or more Board Resolutions
as permitted by Sections 201 and 301, in authenticating such Securities, and accepting the additional responsibilities under this
Indenture in relation to such Securities, the Trustee shall be entitled to receive, in addition to any Officers’ Certificate
and Opinion of Counsel required to be furnished to the Trustee pursuant to Section 102, and (subject to Section 601) shall be fully
protected in relying upon, an Opinion of Counsel to the effect that:

 

		(1)	if the form (or the manner of determining the form) of such Securities has been established by
or pursuant to Board Resolution as permitted by Section 201, that such form has been established in conformity with the provisions
of this Indenture;

 

		(2)	if the terms of such Securities have been, or in the case of Securities of a series offered in
a Periodic Offering, will be, established by or pursuant to a Board Resolution as permitted by Section 301, that such terms have
been, or in the case of Securities of a series offered in a Periodic Offering, will be, established in conformity with the provisions
of this Indenture, subject, in the case of Securities of a series offered in a Periodic Offering, to any conditions specified in
such Opinion of Counsel;

 

		(3)	that such Securities, when authenticated and delivered by the Trustee and issued by the Company
in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations
of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equitable
principles, whether applied in an action at law or in equity, and will be entitled to the benefits of this Indenture, equally and
ratably with all other Securities, if any, of such series Outstanding; and

 

		(4)	such other matters as the Trustee may reasonably request;

 

or, if the authentication and delivery
relates to a new series of Securities created by an indenture supplemental hereto, an Opinion of Counsel to the effect that all
conditions precedent to the execution of the supplemental indenture with respect to that series of Securities have been complied
with, the Company has the power to execute and deliver any such supplemental indenture and has taken all necessary action for those
purposes and any such supplemental indenture has been executed and delivered and constitutes the legal, valid and binding obligation
of the Company enforceable in accordance with its terms (subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equitable
principles, whether applied in an action at law or in equity).

 

Notwithstanding that
such form or terms have been so established, the Trustee shall not be required to authenticate such Securities if the issue of
such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities, under the Securities
and this Indenture or otherwise, in a manner which is not reasonably acceptable to the Trustee.

 

    27

     

    

 

 

Notwithstanding the
provisions of Sections 102, 301 and the preceding paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Board Resolution, Officers’ Certificate, Company Order, Opinion of Counsel
or supplemental indenture otherwise required pursuant thereto at or prior to the time of authentication of each Security of such
series, so long as such documents are delivered at or prior to the authentication upon original issuance of the first Security
of such series to be issued.

 

With respect to Securities
of a series not to be originally issued all at one time, the Trustee may rely upon the Opinion of Counsel and the other documents
delivered pursuant to Sections 201 and 301 and this Section, as applicable, in connection with the first authentication of Securities
of such series and any subsequent request by the Company to the Trustee to authenticate Securities of such series upon their original
issuance shall constitute a representation and warranty by the Company that as of the date of such request, the statements made
in the Officers’ Certificate shall be true and correct as if made on such date.

 

Each Security shall
be dated the date of its authentication.

 

No Security shall be
entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature of an authorized
signatory, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been
duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if
any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section 309 for all purposes of this Indenture, such Security
shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

 

Section
304.     Temporary Securities

 

Pending the preparation
of Definitive Securities of any series, the Company may execute, and upon receipt of the documents required by Sections 102, 201,
301 and 303, as applicable, together with a Company Order, the Trustee shall authenticate and deliver, temporary Securities which
are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the
tenor of the Definitive Securities of like series in lieu of which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of
such Securities.

 

If temporary Securities
of any series are issued, the Company will cause Definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of Definitive Securities of such series, the temporary Securities of such series shall be exchangeable for
Definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company
maintained pursuant to Section 1002 for the purpose of exchanges of Securities of such series, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Securities of any series the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor one or more Definitive Securities of the same series, of any authorized denominations
and of a like aggregate principal amount and tenor. Until so exchanged the temporary Securities of any series shall in all respects
be entitled to the same benefits under this Indenture as Definitive Securities of such series and tenor.

 

    28

     

    

 

Section
305.     Registration, Registration of Transfer and Exchange

 

The Company shall cause
to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of
the Company in a Place of Payment being herein sometimes referred to as the “Security Register”) in which, subject
to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers
of Securities. The Company hereby appoints the Trustee as the initial security registrar for the purpose of registering Securities
and transfers of Securities as herein provided (the registrar responsible for so registering Securities and transfers thereof being
herein sometimes referred to as the “Security Registrar”). The Company may at any time replace such Security
Registrar, change such office or agency or act as its own Security Registrar. The Company will give prompt written notice to the
Trustee of any change of the Security Registrar or of the location of such office or agency. At all reasonable times the Security
Register shall be available for inspection by the Trustee.

 

Upon surrender for
registration of transfer of any Security of any series at the office or agency of the Company maintained pursuant to Section 1002
for such purpose, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee
or transferees, one or more new Securities of the same series, of any authorized denominations and of a like aggregate principal
amount and tenor.

 

At the option of the
Holder, Securities of any series (except a Global Security) may be exchanged for other Securities of the same series, of any authorized
denominations and of a like aggregate principal amount and tenor, upon surrender of the Securities to be exchanged at such office
or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate
and deliver, the Securities which the Holder making the exchange is entitled to receive.

 

All Securities issued
upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer
or exchange.

 

Every Security presented
or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar, duly executed,
by the Holder thereof or its attorney duly authorized in writing.

 

No service charge shall
be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities,
other than exchanges pursuant to Section 304 or 1107 not involving any transfer.

 

    29

     

    

 

Neither the Trustee
nor the Company shall be required (1) to issue, register the transfer of or exchange Securities of any series (or of any series
and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of mailing
of a notice of redemption of Securities of that series selected for redemption under Section 1103 and ending at the close of business
on the day of such mailing, (2) to register the transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part, or (3) to register the transfer of or exchange any
Security between a Regular Record Date and the next succeeding Interest Payment Date.

 

Notwithstanding any
other provision in this Indenture and except as otherwise specified as contemplated by Section 301, no Global Security may be transferred
to, or registered or exchanged for Securities registered in the name of, any Person other than the Depositary for such Global Security
or any nominee thereof, and no such transfer may be registered, except as provided in this paragraph. Every Security authenticated
and delivered upon registration or transfer of, or in exchange for or in lieu of, a Global Security shall be a Global Security,
except as provided in this paragraph. If (1) (A) the Depositary for a Global Security notifies the Company that it is unwilling
or unable to continue as Depositary for such Global Security or ceases to be a clearing agency registered under the Exchange Act,
and (B) a successor Depositary is not appointed by the Company within 90 days, (2) an Event of Default has occurred and is continuing
with respect to the Securities of such series and the Security Registrar has received a request from the Depositary to issue certificated
securities in lieu of all or a portion of the Global Securities of such series (in which case the Company shall deliver certificated
securities within 30 days of such request) or (3) the Company determines in its sole discretion that Securities of a series issued
in global form shall no longer be represented by a Global Security, then such Global Security may be exchanged by such Depositary
for Definitive Securities of the same series, of any authorized denomination and of a like aggregate principal amount and tenor,
registered in the names of, and the transfer of such Global Security or portion thereof may be registered to, such Persons as such
Depositary shall direct.

 

Section
306.     Mutilated, Destroyed, Lost and Stolen Securities

 

If any mutilated Security
is surrendered to the Trustee, together with such security or indemnity as may be required by the Company or the Trustee to save
each of them and any agent of either of them harmless, the Company shall execute and upon its request the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number
not contemporaneously Outstanding.

 

If there shall be delivered
to the Company and the Trustee (1) evidence to their satisfaction of the destruction, loss or theft of any Security and (2) such
security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence
of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute
and upon its request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new
Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously Outstanding. If,
after the delivery of such new Security, a bona fide purchaser of the original Security in lieu of which such new Security was
issued presents for payment or registration such original Security, the Trustee shall be entitled to recover such new Security
from the party to whom it was delivered or any party taking therefrom, except a bona fide purchaser, and shall be entitled to recover
upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Company and
the Trustee in connection therewith.

 

    30

     

    

 

In case any such mutilated,
destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead
of issuing a new Security, pay such Security (and, for clarity, Article XI shall not apply to such payment).

 

Upon the issuance of
any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected
therewith. Every new Security of any series issued pursuant to this Section in exchange for any mutilated Security or in lieu of
any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or
not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all
the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

 

The provisions of this
Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

 

Section
307.     Payment of Interest; Interest Rights Preserved

 

Except as otherwise
provided as contemplated by Section 301 with respect to any series of Securities, interest on any Security which is payable, and
is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or
one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

 

    31

     

    

 

Any interest on any
Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein
called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record
Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case,
as provided in clause (1) or (2) below:

 

		(1)	The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the
Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record
Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee
in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed
payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed
to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior
to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such
Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted
Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less
than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company
of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities
of such series at its address as it appears in the Security Register, not less than 10 days prior to such Special Record Date.
Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted
Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities)
are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause
(2).

 

		(2)	The Company may make payment of any Defaulted Interest on the Securities of any series in any other
lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which such Securities
may be listed or traded, and upon such notice as may be required by such exchange, if, after notice given by the Company to the
Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

 

Subject to the foregoing
provisions of this Section and Section 305, each Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security, shall carry the rights to interest accrued and unpaid, and to accrue, which were
carried by such other Security.

 

For each series of
Securities, the Company shall, prior to 11:00 a.m. (New York City time) (or such later time of day to which the Trustee may agree)
on each payment date for principal and premium, if any, and interest, if any, deposit with the Trustee money in immediately available
funds sufficient to make cash payments due on the applicable payment date.

 

Section
308.     Persons Deemed Owners

 

Except as otherwise
provided as contemplated by Section 301 with respect to any series of Securities, prior to due presentment of a 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 such Security
is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to
Sections 305 and 307) any interest on such Security and for all other purposes whatsoever, whether or not such Security is overdue,
and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

 

    32

     

    

 

No holder of any beneficial
interest in any Global Security held on its behalf by a Depositary shall have any rights under this Indenture with respect to such
Global Security, and such Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as
the owner of such Global Security for all purposes whatsoever. None of the Company, the Trustee nor any agent of the Company or
the Trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.

 

Section
309.     Cancellation

 

In order for any Securities
to be surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment
such Security must be delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the
Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in
any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any
Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall
be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled
as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities held by the Trustee shall
be disposed of in accordance with its customary procedures, and the Trustee shall thereafter, from time to time upon written request,
deliver to the Company a certificate with respect to such disposition.

 

Section
310.     Computation of Interest

 

Except as otherwise
specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed
on the basis of a 360-day year of twelve 30-day months and interest on the Securities of each series for any partial period shall
be computed on the basis of a 360-day year of twelve 30-day months and the number of days elapsed in any partial month.

 

Section
311.     CUSIP Numbers

 

The Company in issuing
the Securities may use CUSIP numbers (in addition to the other identification numbers printed on the Securities), and, if so, the
Trustee shall use CUSIP numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice
may state that no representation is made as to the correctness of such CUSIP numbers either as printed on the Securities or as
contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or omission of such CUSIP numbers. The Company will
promptly notify the Trustee of any change in the CUSIP numbers.

 

    33

Section
401.     Satisfaction and Discharge of Indenture

 

This Indenture shall
upon Company Request cease to be of further effect with respect to Securities of any series (except as to any surviving rights
of registration of transfer or exchange of such Securities herein expressly provided for), and the Trustee, at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture with respect to such Securities,
when

 

		(1)	either

 

		(A)	all such Securities theretofore authenticated and delivered (other than (i) such Securities which
have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306, and (ii) such Securities for
whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid

		(i)	have become due and payable,

 

		(ii)	will become due and payable at their Stated Maturity within one year, or

 

		(iii)	are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company,

                                                                                 

                                                                                and, in the case of clause (i), (ii) or (iii) above, the Company has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for this purpose an amount of money in the currency or currency units in which such Securities are payable sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal and any premium and interest to the date of such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be;

 

		(2)	the Company has paid or caused to be paid all other sums payable hereunder by the Company with
respect to such Securities; and

 

		(3)	the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel,

Trustee under Section 607, the obligations of the Trustee to any Authenticating Agent under Section 614 and the right of the Trustee
to resign under Section 610 shall survive, and (ii) if money shall have been deposited with the Trustee pursuant to clause (1)(B)
above, the obligations of the Company and/or the Trustee under Sections 402, 606, 701 and 1002 and the last paragraph of Section
1003 shall survive.

 

Section
402.     Application of Trust Money

 

Subject to the provisions
of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Section 401 shall be held in trust and
applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through
any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto,
of the principal and any premium and interest for whose payment such money has been deposited with the Trustee, but such money
need not be segregated from other funds except to the extent required by law.

 

Article
V

DEFAULTS AND REMEDIES

 

Section
501.     Events of Default

 

“Event of
Default”, wherever used herein with respect to Securities of any series, means any one of the following events (whatever
the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

 

		(1)	default in the payment of any interest upon any Security of that series when it becomes due and
payable, and continuance of such default for a period of 30 days (whether or not such payment is prohibited by the provisions of
Article XIV hereof); or

 

		(2)	default in the payment of the principal of (or premium, if any, on) any Security of that series
at its Maturity (whether or not such payment is prohibited by the provisions of Article XIV hereof); or

 

		(3)	default in the performance, or breach, of any term, covenant or warranty of the Company in this
Indenture (other than a term, covenant or warranty a default in whose performance or whose breach is elsewhere in this Section
specifically dealt with or which has expressly been included in this Indenture solely for the benefit of series of Securities other
than that series), and continuance of such default or breach for a period of 90 days after there has been given, by registered
or certified mail, to the Company by the Trustee or to the Company and the Trustee by Holders of at least 25% in principal amount
of the Outstanding Securities of that series a written notice specifying such default or breach and requiring it to be remedied
and stating that such notice is a notice of Default hereunder; or

 

    35

     

    

 

		(4)	the Company pursuant to or within the meaning of any Bankruptcy Law (A) commences a voluntary case,
(B) consents to the entry of any order for relief against it in an involuntary case, (C) consents to the appointment of a Custodian
of it or for all or substantially all of its property, or (D) makes a general assignment for the benefit of its creditors; or

 

		(5)	a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (A) is
for relief against the Company in an involuntary case, (B) appoints a Custodian of the Company or for all or substantially all
of its property, or (C) orders the liquidation of the Company; and the order or decree remains unstayed and in effect for 90 days;
or

 

		(6)	any other Event of Default provided as contemplated by Section 301 with respect to Securities of
that series.

 

Section
502.     Acceleration of Maturity; Rescission and Annulment

 

If an Event of Default
with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee
or Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount
of (or, if any of the Securities of that series are Original Issue Discount Securities, such portion of the principal amount of
such Securities as may be specified in the terms thereof) all of the Securities of that series to be due and payable immediately,
by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount
(or specified amount) shall become immediately due and payable.

 

At any time after such
declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment
of the money due has been obtained by the Trustee as hereinafter in this Article provided, Holders of a majority in principal amount
of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration
and its consequences if

 

		(1)	the Company has paid or deposited with the Trustee a sum sufficient to pay

 

		(A)	all overdue interest on all Securities of that series,

 

		(B)	the principal of (and premium, if any, on) any Securities of that series which have become due
otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities,

 

		(C)	to the extent that payment of such interest is lawful, interest upon overdue interest at the rate
or rates prescribed therefor in such Securities, and

 

    36

     

    

 

		(D)	all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel; and

 

		(2)	all Events of Default with respect to Securities of that series, other than the non-payment of
the principal of Securities of that series which have become due solely by such declaration of acceleration, have been cured or
waived as provided in Section 513.

 

No such rescission
shall affect any subsequent Default or impair any right consequent thereon.

 

Section
503.     Collection of Indebtedness and Suits for Enforcement by Trustee

 

The Company covenants
that if

 

		(1)	default is made in the payment of any interest on any Security when such interest becomes due and
payable and such default continues for a period of 30 days (whether or not such payment is prohibited by the provisions of Article
XIV hereof), or

 

		(2)	default is made in the payment of the principal of (or premium, if any, on) any Security at the
Maturity thereof (whether or not such payment is prohibited by the provisions of Article XIV hereof),

 

then the Company will, upon demand of the
Trustee, pay to it, for the benefit of Holders of such Securities, the whole amount then due and payable on such Securities for
principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest
on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor in such Securities,
and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and other amounts due to the
Trustee pursuant to Section 607.

 

If the Company fails
to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute
a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree
and may enforce the same against the Company, or any other obligor upon such Securities and collect the moneys adjudged or decreed
to be payable in the manner provided by law out of the property of the Company, or any other obligor upon such Securities, wherever
situated.

 

If an Event of Default
with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in
this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

 

    37

     

    

 

Section
504.     Trustee May File Proofs of Claim

 

In case of any judicial
proceeding relative to the Company, or any other obligor upon the Securities, their property or their creditors, the Trustee shall
be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust
Indenture Act in order to have claims of Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall
be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the
same; and any Custodian, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder
to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to
Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee under Section 607.

 

No provision of this
Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize
the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may,
on behalf of Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’
or other similar committee.

 

Section
505.     Trustee May Enforce Claims Without Possession of Securities

 

All rights of action
and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment
of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and any other amounts
due to the Trustee under Section 607, be for the ratable benefit of Holders of the Securities in respect of which such judgment
has been recovered.

 

Section
506.     Application of Money Collected

 

Any money or property
collected or to be applied by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates
fixed by the Trustee and, in case of the distribution of such money or property on account of principal or any premium or interest,
upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

 

FIRST: to the payment
of all amounts due the Trustee under Section 607;

 

SECOND: subject to
Article XIV, to the payment of the amounts then due and unpaid for principal of and any premium and interest on the Securities
in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind,
according to the amounts due and payable on such Securities for principal and any premium and interest, respectively; and THIRD:
the balance, if any, to the Company.

 

    38

     

    

 

Section
507.     Limitation on Suits

 

No Holder of any Security
of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture or a Security,
or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

 

		(1)	such Holder has previously given written notice to the Trustee of a continuing Event of Default
with respect to the Securities of that series;

 

		(2)	Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall
have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee
hereunder;

 

		(3)	such Holder or Holders have offered and, if requested, provided to the Trustee security or indemnity
reasonably acceptable to the Trustee against the costs, expenses and liabilities that may be incurred in compliance with such request;

 

		(4)	the Trustee for 60 days after its receipt of such notice, request and offer and, if requested,
provision of such security or indemnity has failed to institute any such proceeding; and

 

		(5)	no direction inconsistent with such written request has been given to the Trustee during such 60-day
period by Holders of a majority in principal amount of the Outstanding Securities of that series;

 

it being understood and intended that no
one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this
Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and
for the equal and ratable benefit of all of such Holders.

 

Section
508.     Unconditional Right of Holders to Receive Principal, Premium and Interest

 

Notwithstanding any
other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of and any premium and (subject to Sections 305 and 307) interest on such Security on the respective Stated
Maturity expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement
of any such payment, and such rights shall not be impaired without the consent of such Holder.

 

Section
509.     Restoration of Rights and Remedies

 

If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then in every such case, subject
to any determination in such proceeding, the Company, the Trustee and Holders shall be restored severally and respectively to their
former positions hereunder, and thereafter all rights and remedies of the Trustee and Holders shall continue as though no such
proceeding had been instituted.

 

    39

     

    

 

Section
510.     Rights and Remedies Cumulative

 

Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of
Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to Holders is intended to be exclusive of any
other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every
other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate
right or remedy.

 

Section
511.     Delay or Omission Not Waiver

 

No delay or omission
of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy
given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders, as the case may be.

 

Section
512.     Control by Holders

 

Subject to the provisions
of Sections 507 and 603, Holders of a majority in aggregate principal amount of the Outstanding Securities of any series shall
have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee, with respect to the Securities of such series; provided, however, that

 

		(1)	such direction shall not be in conflict with any rule of law or with this Indenture;

 

		(2)	the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with
such direction; and

 

		(3)	subject to the provisions of Section 601, the Trustee shall have the right to decline to follow
any such direction if the Trustee in good faith shall determine that the proceeding so directed would involve the Trustee in personal
liability or would otherwise be contrary to applicable law.

 

    40

     

    

 

Section
513.     Waiver of Past Defaults

 

Holders of a majority
in aggregate principal amount of the Outstanding Securities of any series may on behalf of Holders of all the Securities of such
series waive any past default hereunder with respect to such series and its consequences, except

 

		(1)	a continuing default in the payment of the principal of or any premium or interest on any Security
of such series, or

 

		(2)	a default in respect of a covenant or provision hereof which under Article IX cannot be modified
or amended without the consent of the Holder of each Outstanding Security of such series affected.

 

Upon any such waiver,
such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture, but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

 

Section
514.     Undertaking for Costs

 

In any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted
by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and
may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided,
however, that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking
or to make such an assessment in any suit instituted by the Trustee or the Company, in any suit instituted by any Holder (or group
of Holders) holding in the aggregate more than 10% in principal amount of the Outstanding Securities of any series to which the
suit relates, or in any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any)
or interest on any Security on or after the respective Stated Maturity expressed by such Security (or, in the case of redemption
or repayment, on or after the Redemption Date).

THE TRUSTEE

 

Section
601.     Certain Duties and Responsibilities

 

(a)       
Except during the continuance of an Event of Default with respect to any series of Securities:

 

		(1)	the Trustee undertakes to perform such duties and only such duties as are specifically set forth
in this Indenture with respect to the Securities of such series, and no implied covenants or obligations shall read into this Indenture
against the Trustee; and

 

		(2)	in the absence of bad faith on its part, the Trustee may, with respect to Securities of such series,
conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or
opinions furnished to the Trustee conforming to the requirements of this Indenture; but in the case of any such certificates or
opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty
to examine the same to determine whether or not they conform on their face to the requirements of this Indenture.

 

    41

     

    

 

(b)              
In case an Event of Default with respect to any series of Securities has occurred and is continuing, the Trustee shall exercise
with respect to the Securities of such series such rights and powers vested in it by this Indenture, and use the same degree of
care and skill in their exercise, as a prudent Person would exercise or use under the circumstances in the conduct of such person’s
own affairs.

 

(c)              
No provisions of this Indenture shall be construed to relieve the Trustee from liability for its own grossly negligent action,
its own grossly negligent failure to act, or its own willful misconduct, except that:

 

		(1)	this Subsection shall not be construed to limit the effect of clause (a) above;

 

		(2)	the Trustee shall not be liable for any error of judgment made in good faith by a responsible officer,
unless it shall be proved that the Trustee was grossly negligent in ascertaining the pertinent facts;

 

		(3)	the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in
good faith in accordance with the direction of the Holders or a majority in principal amount of the Outstanding Securities of any
series relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee, under this Indenture with respect to the Securities of such series; and

 

		(4)	no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers.

 

(d)              
Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the
liability of or affording protection to the Trustee shall be subject to the provisions of this Section.

 

Section
602.     Notice of Defaults

 

Subject to the following
paragraph, if a Default occurs and is continuing with respect to the Securities of any series, the Trustee shall, within 90 days
after it occurs, transmit, in the manner and to the extent provided in Section 313(c) of the Trust Indenture Act, notice of all
uncured or unwaived Defaults known to it; provided, however, that, except in the case of a Default in payment on the Securities
of any series, the Trustee shall be protected in withholding the notice if and so long as the board of directors, the executive
committee or a trust committee of directors or responsible officers of the Trustee determine in good faith that withholding such
notice is in the interests of Holders of Securities of such series; provided, further, however, that, in the case of any
Default specified in Section 501(3) with respect to the Securities of such series, no such notice to Holders shall be given until
at least 90 days after the occurrence thereof.

 

The Trustee shall not
be deemed to have notice or be charged with knowledge of any Default, except a Default under Sections 501(1) or 501(2) herein,
unless the Trustee shall have received from the Company or from any Holder written notice thereof at its Corporate Trust Office,
and such notice references the Securities in this Indenture. In the absence of any such notice, the Trustee may conclusively assume
that no such Default exists.

 

    42

     

    

 

Section
603.     Certain Rights of Trustee

 

Subject to the provisions
of Section 601:

 

		(1)	the Trustee may rely on and shall be protected in acting or refraining from acting upon any resolution,
certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence
of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party
or parties;

 

		(2)	any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced
by a Company Request or Company Order (or in the case of a Periodic Offering, as agreed in procedures set forth in a Company Order
pursuant to Section 303) and any resolution of the Board of Directors shall be sufficiently evidenced by a Board Resolution;

 

		(3)	whenever in the administration of this Indenture the Trustee shall deem it desirable that a matter
be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee (unless other evidence be herein
specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’ Certificate;

 

		(4)	the Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel
shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in
good faith and in reliance thereon;

 

		(5)	the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by
this Indenture at the request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered
to the Trustee security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by
it in compliance with such request or direction;

 

		(6)	the Trustee shall not be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note,
other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may, without obligation to do so,
make such further inquiry or investigation into such facts or matters as it may see fit; and, if the Trustee shall determine to
make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally
or by agent or attorney and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation;

 

    43

     

    

 

		(7)	the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either
directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the
part of any agent or attorney appointed with due care by it hereunder;

 

		(8)	the Trustee may request that the Company deliver an Officers’ Certificate setting forth the
names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which
Officers’ Certificate may be signed by any Person authorized to sign an Officers’ Certificate, including any Person
specified as so authorized in any such certificate previously delivered and not superseded;

 

		(9)	the rights, privileges, protections, immunities and benefits given to the Trustee, including its
right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each
agent, custodian and other Person employed to act hereunder; and

 

		(10)	in no event shall the Trustee be responsible or liable for special, indirect or consequential loss
or damage of any kind whatsoever (including but not limited to loss of profit) irrespective of whether the Trustee has been advised
of the likelihood of such loss or damage and regardless of the form of action.

 

Section
604.     Not Responsible for Recitals or Issuance of Securities

 

The recitals contained
herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the
Company, and the Trustee or any Authenticating Agent assumes no responsibility for their correctness. Neither the Trustee nor any
Authenticating Agent makes any representations as to the validity or sufficiency of this Indenture or of the Securities. Neither
the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds
thereof.

 

Section
605.     May Hold Securities

 

The Trustee, any Authenticating
Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or any other capacity, may
become the owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal with the Company with the same
rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

 

Section
606.     Money Held in Trust

 

Money held by the Trustee
in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise agreed with the Company.

 

    44

     

    

 

Section
607.     Compensation and Reimbursement

 

The Company agrees:

 

		(1)	to pay to the Trustee from time to time such compensation for all services rendered by it hereunder
as shall be mutually agreed upon by the Company and the Trustee in writing (which compensation shall not be limited by any provision
of law in regard to the compensation of a trustee of an express trust);

 

		(2)	to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the
expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable
to its gross negligence or bad faith; and

 

		(3)	to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred
without gross negligence, willful misconduct or bad faith on its part, arising out of or in connection with the acceptance or administration
of the trust or trusts hereunder, including the costs and expenses of defending itself against any claim or liability in connection
with the exercise or performance of any of its powers or duties hereunder (and the reasonable fees and disbursements of its agents,
attorneys, accountants and experts and taxes (other than taxes based upon, measured by or determined by the income of the Trustee)).
The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify
the Company will not relieve the Company of its obligations under this Section, except to the extent the Company has been prejudiced
thereby. Upon the election of the Company, the Company will have the right to assume the defense of the claim, and the Trustee
will cooperate in the defense. The Trustee may have separate counsel at its own expense, but if the Trustee has been reasonably
advised by counsel that there is an actual or potential conflict of interest or may be one or more legal defenses available to
it that are different from or additional to those available to the Company and in the reasonable judgment of such counsel it is
advisable for the Trustee to engage separate counsel, then the Company will pay the reasonable fees and expenses of such counsel.
The Company need not pay for any settlement made without its consent, which consent will not be unreasonably withheld. Notwithstanding
the foregoing, in no event shall the Company have the right, without the Trustee’s consent, to settle any such claim if such
settlement (i) arises from or is part of any criminal action, suit or proceeding, (ii) contains a stipulation to, confession of
judgment with respect to, or admission or acknowledgement of, any liability or wrongdoing on the part of the Trustee, (iii) provides
for injunctive relief, or other relief other than monetary damages, or (iv) does not contain an unconditional release of the Trustee
from all liability on all claims that are the subject matter of the related dispute or proceeding.

 

The obligations of
the Company under this Section to compensate the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances
shall constitute additional indebtedness hereunder.

 

    45

     

    

 

The Trustee shall have
a lien prior to the Securities upon all property and funds held or collected by it as such for any amount owing to it pursuant
to this Section 607, except with respect to funds held in trust for the benefit of the Holders.

 

Without limiting any
rights available to the Trustee under applicable law, when the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 501(4) or Section 501(5), the expenses (including the reasonable charges and expenses of
its counsel) and the compensation for such services are intended to constitute expenses of administration under any applicable
Bankruptcy Law.

 

The provisions of this
Section shall survive the satisfaction and discharge of this Indenture and the Defeasance or Covenant Defeasance of the Securities
and the resignation or removal of the Trustee.

 

Section
608.     Disqualification; Conflicting Interests

 

If the Trustee has
or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and
this Indenture.

 

Section
609.     Corporate Trustee Required; Eligibility

 

There shall at all
times be one or more Trustees hereunder with respect to the Securities of each series, at least one of which shall be a Person
that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus required by the Trust
Indenture Act. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of a supervising
or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed
to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

 

Section
610.     Resignation and Removal; Appointment of Successor

 

No resignation or removal
of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee in accordance with the applicable requirements of Section 611.

 

The Trustee may resign
at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument
of acceptance by a successor Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days after
the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment
of a successor Trustee with respect to the Securities of such series.

 

The Trustee may be
removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and to the Company. If an instrument of acceptance by a successor
Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the removed Trustee
may petition any court of competent jurisdiction for the appointment of a successor Trustee.

 

    46

     

    

 

If at any time:

 

		(1)	the Trustee shall fail to comply with Section 608 after written request therefor by the Company
or by any Holder who has been a bona fide Holder of a Security for at least six months, or

 

		(2)	the Trustee shall cease to be eligible under Section 609 and shall fail to resign after written
request therefor by the Company or by any such Holder, or

 

		(3)	the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a
receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee
or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

 

then, in any such case, (A) the Company,
acting pursuant to the authority of a Board Resolution, may remove the Trustee with respect to all Securities, or (B) subject to
Section 514, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities
and the appointment of a successor Trustee or Trustees.

 

If the Trustee shall
resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees
with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with
respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect
to the Securities of any particular series) and shall comply with the applicable requirements of Section 611. If, within one year
after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities
of any series shall be appointed by Act of Holders of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment in accordance with the applicable requirements of Section 611, become the successor Trustee with respect to the Securities
of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or Holders and accepted appointment in the manner required
by Section 611, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of such series.

 

The Company shall give
notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the manner provided
in Section 106. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the
address of its Corporate Trust Office.

 

    47

     

    

 

Section
611.     Acceptance of Appointment by Successor

 

(a)     
In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee
so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment,
and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee, and
all property and money held by such retiring Trustee hereunder; but, on the request of the Company or the successor Trustee, such
retiring Trustee shall, upon payment of its charges and subject to any claim provided for in Section 607, execute and deliver an
instrument transferring to such successor Trustee all the rights, powers, trusts and duties of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

 

(b)     
In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all)
series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall
execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (i)
shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee
all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (ii) if the retiring Trustee is not retiring with respect to all Securities,
shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring
shall continue to be vested in the retiring Trustee, and (iii) shall add to or change any of the provisions of this Indenture as
shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood
that nothing herein or in such supplemental indenture shall constitute such Trustees as co-trustees of the same trust and that
each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered
by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the
retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act,
deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to
the Securities of that or those series to which the appointment of such successor Trustee relates, but, on request of the Company,
or any successor Trustee, such retiring Trustee shall, upon payment of its charges and subject to any claim provided for in Section
607, duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder
with respect to the Securities of that or those series to which the appointment of such successor Trustee relates.

 

(c)     
Upon the reasonable request of any such successor Trustee, the Company shall execute any and all instruments for more fully
and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in clause (a)
or (b) above.

 

    48

     

    

 

 

(d)              
No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be
qualified and eligible under this Article.

 

Section
612.     Merger, Conversion, Consolidation or Succession to Business

 

Any Corporation into
which the Trustee may be merged or converted or with which it may be consolidated, or any Corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any Corporation succeeding to all or substantially all the
corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such Corporation shall
be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then
in office, any successor by merger, conversion or consolidation to such authenticating Trustee shall adopt such authentication
and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

 

Section
613.     Preferential Collection of Claims Against Company

 

If and when the Trustee
shall be or become a creditor of the Company, or any other obligor upon the Securities, the Trustee shall be subject to the provisions
of the Trust Indenture Act regarding the collection of claims against the Company or any such other obligor.

 

Section
614.     Appointment of Authenticating Agent

 

The Trustee (upon notice
to the Company) may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized
to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue (in accordance with procedures
acceptable to the Trustee) and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 306,
and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes
as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of
Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication
and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the
Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a Corporation
organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized
under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section,
the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance
with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified
in this Section.

 

    49

     

    

 

Any Corporation into
which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any Corporation resulting from
any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any Corporation succeeding to all
or substantially all of the corporate agency or corporate trust business of such Authenticating Agent, shall continue to be an
Authenticating Agent, provided such Corporation shall be otherwise eligible under this Section, without the execution or filing
of any paper or any further act on the part of the Trustee or such Authenticating Agent.

 

An Authenticating Agent
may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving
such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible
in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable
to the Company. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the
rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No
successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

 

Except with respect
to an Authenticating Agent appointed at the request of the Company, the Trustee agrees to pay to each Authenticating Agent from
time to time reasonable compensation (for which the Company shall not be responsible) for its services under this Section.

 

If an appointment with
respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in addition
to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form:

 

This is one of the
Securities of the series designated therein referred to in the within-mentioned Indenture.

COVENANTS

 

Section
1001.     Payment of Principal, Premium and Interest

interest on the Securities of that series in accordance with the terms of the Securities and this Indenture.

 

Section
1002.     Maintenance of Office or Agency

 

The Company will maintain
in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered
for payment, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and
demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. The Company will give
prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time
the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

 

The Company may also
from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no
such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each
Place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of
any such designation or rescission and of any change in the location of any such other office or agency.

Place of Payment for each series of Securities the Corporate Trust Office, and initially appoints the Trustee at its Corporate
Trust Office as the Paying Agent, as the Company’s office or agency for each such purpose.

 

With respect to any
Global Security, and except as otherwise may be specified for such Global Security as contemplated by Section 301, the Corporate
Trust Office shall be the Place of Payment where such Global Security may be presented or surrendered for payment or for registration
of transfer or exchange, or where successor Securities may be delivered in exchange therefor; provided, however,
that any such payment, presentation, surrender or delivery effected pursuant to the applicable procedures of the Depositary for
such Global Security shall be deemed to have been effected at the Place of Payment for such Global Security in accordance with

Section
1003.     Money for Securities Payments to Be Held in Trust

 

If the Company or any
of its Subsidiaries shall at any time act as Paying Agent with respect to any series of Securities, it will, on or before each
due date of the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due
until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee
of its action or failure so to act.

 

Whenever the Company
shall have one or more Paying Agents for any series of Securities, it will, on or prior to each due date of the principal of or
any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such
sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly
notify the Trustee of its action or failure so to act.

 

The Company will cause
each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which
such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) hold
all sums held by it for the payment of the principal of (and premium, if any) or interest, if any, on Securities of that series
in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of
as herein provided; (2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities of that
series) in the making of any payment of principal (and premium, if any) or interest, if any, on the Securities of that series;
and (3) during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums
held in trust by such Paying Agent for payment in respect of the Securities of that series.

 

The Company may at
any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be
held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon
such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to
such money.

 

Any money deposited
with the Trustee or any Paying Agent in trust for the payment of the principal of or any premium or interest on any Security of
any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be
paid to the Company pursuant to a Company Request and the Trustee or any Paying Agent shall be discharged from such trust; and
the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the state whose escheat laws control
for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before
being required to make any such payment, may at the expense of the Company cause to be published once, in an Authorized Newspaper,
notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the

Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance and
observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement
of notice provided hereunder) and, if the Company shall be in default, specifying all such Defaults and the nature and status thereof
of which they may have knowledge.

 

The Company will notify
the Trustee of any change in the Company’s Fiscal Year.

1005.     Waiver of Certain Covenants

to the Securities of any series if before the time for such compliance Holders of at least a majority in aggregate principal amount
of the Outstanding Securities of all affected series (voting as one class) shall, by Act of such Holders, either waive such compliance
in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect
such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full
force and effect.

 

A waiver which changes
or eliminates any term, provision or condition of this Indenture which has expressly been included solely for the benefit of one
or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect
to such term, provision or condition, shall be deemed not to affect the rights under this Indenture of the Holders of Securities
of any other series.

Section
1103.     Selection by Trustee of Securities to be Redeemed

 

If less than all the
Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed),
the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from
the Outstanding Securities of such series not previously called for redemption, on a pro rata basis that complies with any
securities exchange or other applicable requirements for redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple in excess thereof) of the principal amount of Securities of such series of a
denomination larger than the minimum authorized denomination for Securities of that series.

 

The Trustee shall promptly
notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for partial
redemption, the principal amount thereof to be redeemed.

 

For all purposes of
this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in
the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which
has been or is to be redeemed.

 

Section
1104.     Notice of Redemption

 

Notice of redemption
shall be given by first-class mail (if international mail, by air mail), postage prepaid, mailed not less than 30 nor more than
60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at its address appearing in the Security Register,

or Covenant Defeasance or a discharge pursuant to Article IV.

 

All notices of redemption

notice, the method for calculating the Redemption Price,

the identification (and, in the case of partial redemption of any Securities, the principal amounts) of the particular Securities
to be redeemed,

 

    59

     

    

 

		(4)	that on the Redemption Date the Redemption Price will become due and payable upon each such Security
to be redeemed and that, unless the Company defaults in the payment of the Redemption Price, interest on such Security will cease
to accrue on and after said date,

prior to the date on which notice is to be given, by the Trustee in the name and at the expense of the Company.

 

Section
1105.     Deposit of Redemption Price

 

On or prior to 11:00
a.m. (New York City time) on any Redemption Date (or such later time of day to which the Trustee may agree), the Company shall
deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust
as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall
be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date. The Trustee shall not
be required to make any such deposit in the event that the Company fails to do so. The contemplated redemption shall be conditioned
on the deposit by the Company of the required moneys thereby. The Trustee and any Paying Agent promptly shall pay or return to
the Company upon Company Request any money held by them that has been deposited pursuant to this Section in excess of the amounts
required to pay such Redemption Price.

 

Section
1106.     Securities Payable on Redemption Date

 

Notice of redemption
having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption
Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price
and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance
with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption
Date; provided, however, that, unless otherwise specified as contemplated by Section 301, installments of interest whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions
of Section 307.

 

If any Security called
for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear
interest from the Redemption Date at the rate prescribed therefor in the Security.

Section
1107.     Securities Redeemed in Part

is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires,
due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the
Holder thereof or its attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and
deliver to the Holder of such Security without service charge to such Holder, a new Security or Securities of the same series and
of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange
for the unredeemed portion of the principal of the Security so surrendered.

of all or any part of any sinking fund payment with respect to the Securities of such series required to be made pursuant to the
terms of such Securities as provided for by the terms of such series; provided that such Securities have not been previously
so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in
such Securities for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section
1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated

deposit, and the granting of any liens in connection therewith);

 

		(5)	such Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of
the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act);

 

		(6)	such Defeasance shall not result in a breach or violation of, or constitute a default under, any
other agreement or instrument to which the Company is a party or by which it is bound;

 

		(7)	such Defeasance shall not result in the trust arising from such deposit constituting an investment
company within the meaning of the Investment Company Act of 1940, as amended, unless such trust shall be registered under such
Act or exempt from registration thereunder; and

 

		(8)	the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel,
each stating that all conditions precedent provided for relating to the Defeasance contemplated by this provision have been complied
with.

 

For this purpose, such
Defeasance means that the Company and any other obligor upon the Securities of such series shall be deemed to have paid and discharged
the entire debt represented by the Securities of such series, which shall thereafter be deemed to be “Outstanding”
only for the purposes of Section 1304 and the rights and obligations referred to in clause (i) through (vii), inclusive, of the
first paragraph of this Section, and to have satisfied all its other obligations under the Securities of such series and this Indenture
insofar as the Securities of such series are concerned.

 

    63

     

    

 

Section
1303.     Covenant Defeasance

 

The Company and any
other obligor shall be released on the 91st day after the date of the deposit referred to in clause (1) below from its obligations
under Section 704 and Article VIII with respect to the Securities of any series on and after the date the conditions set forth
below are satisfied (“Covenant Defeasance”), and the Securities of such series shall thereafter be deemed to
be not “Outstanding” for the purposes of any request, demand, authorization, direction, notice, waiver, consent or
declaration or other action or Act of Holders (and the consequences of any thereof) in connection with such covenants, but shall
continue to be deemed Outstanding for all other purposes hereunder. For this purpose, such Covenant Defeasance means that, with
respect to the Securities of such series, the Company may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such Section, whether directly or indirectly by reason of any reference elsewhere herein
to such Section or by reason of any reference in such Section to any other provision herein or in any other document and such omission
to comply shall not constitute a Default or an Event of Default under Section 501, but, except as specified above, the remainder
of this Indenture and the Securities of such series shall be unaffected thereby. The following shall be the conditions to Covenant
Defeasance:

 

		(1)	the Company has irrevocably deposited or caused to be deposited with the Trustee as trust funds
in trust, for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the
benefit of Holders of the Securities of such series (A) cash in an amount, or (B) in the case of any series of Securities the payments
on which may only be made in legal coin or currency of the United States, U.S. Government Obligations, maturing as to principal
and interest at such times and in such amounts as will insure the availability of cash, or (C) a combination thereof, in each case
sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, to pay (i) the principal and interest and premium, if any, on all Securities of such series on
each date that such principal, interest or premium, if any, is due and payable or on any Redemption Date established pursuant to
clause (3) below, and (ii) any mandatory sinking fund payments on the day on which such payments are due and payable in accordance
with the terms of the Indenture and the Securities of such series;

 

		(2)	the Company has delivered to the Trustee an Opinion of Counsel which shall confirm that Holders
of the Securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of such deposit
and Covenant Defeasance and will be subject to federal income tax on the same amount and in the same manner and at the same time
as would have been the case if such deposit and Covenant Defeasance had not occurred;

 

		(3)	if the Securities are to be redeemed prior to Stated Maturity (other than from mandatory sinking
fund payments or analogous payments), notice of such redemption shall have been duly given pursuant to this Indenture or provision
therefor satisfactory to the Trustee shall have been made;

 

    64

     

    

 

		(4)	no Default or Event of Default shall have occurred and be continuing on the date of such deposit
(other than any Default or Event of Default resulting from the incurrence of Debt the proceeds of which are to be applied to such
deposit, and the granting of any liens in connection therewith);

 

		(5)	such Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the
meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act);

 

		(6)	such Covenant Defeasance shall not result in a breach or violation of, or constitute a default
under, any other agreement or instrument to which the Company is a party or by which it is bound;

 

		(7)	such Covenant Defeasance shall not result in the trust arising from such deposit constituting an
investment company within the meaning of the Investment Company Act of 1940, as amended, unless such trust shall be registered
under such Act or exempt from registration thereunder; and

 

		(8)	the Company has delivered to the Trustee an Officers’ Certificate and Opinion of Counsel
stating that all conditions precedent provided for relating to the Covenant Defeasance contemplated by this provision have been
complied with.

 

Section
1304.     Application by Trustee of Funds Deposited for Payment of Securities

 

Subject to the provisions
of the last paragraph of Section 1003, all moneys or U.S. Government Obligations deposited with the Trustee pursuant to Section
1302 or 1303 (and all funds earned on such moneys or U.S. Government Obligations) shall be held in trust and applied by it to the
payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent), to Holders of the
particular Securities of such series for the payment or redemption of which such moneys have been deposited with the Trustee, of
all sums due and to become due thereon for principal and interest; but such money need not be segregated from other funds except
to the extent required by law.

 

Section
1305.     Repayment to Company

 

The Trustee and any
Paying Agent promptly shall pay or return to the Company upon Company Request any money and U.S. Government Obligations held by
them at any time that have been deposited pursuant to Section 1302 or 1303, which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification delivered to the Trustee, are in excess of the amounts required
to effect the Defeasance or Covenant Defeasance with respect to the Outstanding Securities in question.

 

The provisions of the
last paragraph of Section 1003 shall apply to any money held by the Trustee or any Paying Agent under this Article that remains
unclaimed for two years after the Maturity of any series of Securities for which money or U.S. Government Obligations have been
deposited pursuant to Section 1302 or 1303.

 

    65

     

    

 

Section
1306.     Reinstatement

 

If the Trustee or the
Paying Agent is unable to apply any money or U. S. Government Obligations in accordance with this Article by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the obligations of the Company under this Indenture and the Securities of the applicable series shall be revived
and reinstated as though no deposit had occurred pursuant to this Indenture until such time as the Trustee or the Paying Agent
is permitted to apply all such money or U. S. Government Obligations in accordance with this Article; provided, however,
that if the Company has made any payment of principal of or interest on any Securities of such series because of the reinstatement
of its obligations, the Company shall be subrogated to the rights of Holders of such Securities to receive such payment from the
money or U.S. Government Obligations held by the Trustee or the Paying Agent.

FIRST SUPPLEMENTAL
INDENTURE (this “Supplemental Indenture”), dated as of May 15, 2020, between FIRST INTERSTATE BANCSYSTEM, INC.,
a Montana corporation (the “Company”), and U.S. BANK NATIONAL ASSOCIATION, a national banking association organized
and existing under the laws of the United States of America, as trustee (“Trustee”).

 

RECITALS OF THE COMPANY

 

The Company and the
Trustee will have executed and delivered a Subordinated Debt Securities Indenture dated as of the date hereof (the “Base
Indenture” and, as the same may from time to time be amended, supplemented or otherwise modified in accordance therewith,
including by this Supplemental Indenture, the “Indenture”), to provide for the issuance from time to time by
the Company of its unsecured subordinated indebtedness to be issued in one or more series as provided in the Indenture.

 

The Company desires
to issue and sell on the date hereof One Hundred Million Dollars ($100,000,000) aggregate principal amount of a new series of Securities
of the Company designated as its 5.25% Fixed-to-Floating Rate Subordinated Notes due 2030 (the “Notes”), and
such issuance and sale have been authorized by resolutions duly adopted by the Board of Directors of the Company and by the Pricing
Committee of the Board of Directors of the Company.

 

The Company desires
to establish the terms of the Notes.

 

The Company acknowledges
that all things necessary to make this Supplemental Indenture a legal, binding and enforceable instrument, and to make the Notes,
when executed by the Company and authenticated and delivered by the Trustee, the legal, binding and enforceable obligations of
the Company in accordance with their terms and the terms of the Base Indenture, have been done.

 

The Company has complied
with all conditions precedent provided for in the Base Indenture relating to this Supplemental Indenture.

 

The Company has requested
that the Trustee execute and deliver this Supplemental Indenture.

 

NOW, THEREFORE, THIS
SUPPLEMENTAL INDENTURE WITNESSETH:

 

For and in consideration
of the premises and the purchase of the Notes by the Holders thereof, it is mutually agreed, for the equal and proportionate benefit
of all Holders of the Notes, as follows:

 

ARTICLE I.

 

SCOPE OF SUPPLEMENTAL INDENTURE

 

Section 1.01 Scope.

 

This Supplemental Indenture
constitutes an indenture supplemental 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 hereof and thereof are contained in one instrument. All provisions included in
this Supplemental Indenture supersede any conflicting provisions included in the Base Indenture unless not permitted by law. Except
as expressly amended by the Supplemental Indenture, the terms and provisions of the Base Indenture shall remain in full force and
effect. Notwithstanding the foregoing, this Supplemental Indenture shall only apply to the Notes.

 

ARTICLE II.

 

DEFINITIONS

 

Section 2.01 Definitions and Other Provisions
of General Application. For all purposes of this Supplemental Indenture, except as otherwise expressly provided or unless the
context otherwise requires:

 

	 	(1)	all terms used in this Supplemental Indenture which are not otherwise defined herein shall have the meanings assigned to them in the Base Indenture and include the plural as well as the singular; and

 

	 	(2)	Section 101 of the Base Indenture is amended and supplemented by inserting the following additional defined terms in their appropriate alphabetical positions (and, in the case of any defined term which is duplicated in Section 101 of the Base Indenture, by deleting the duplicate definition set forth in such Section 101 in its entirety):

 

    1

     

    

 

“Additional
Notes” has the meaning specified in Section 3.02(b).

 

“Administrative
or Judicial Action” has the meaning specified in the definition of “Tax Event.”

 

“Benchmark”
means, initially, Three-Month Term SOFR; provided that if the Calculation Agent determines on or prior to the Reference
Time for any Interest Period that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect
to Three-Month Term SOFR or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement
for such Interest Period and any subsequent Interest Periods.

 

“Benchmark
Replacement” means the Interpolated Benchmark with respect to the then-current Benchmark, plus the Benchmark Replacement
Adjustment for such Benchmark; provided that if (a) the Calculation Agent cannot determine the Interpolated Benchmark as
of the Benchmark Replacement Date or (b) the then-current Benchmark is Three-Month Term SOFR and a Benchmark Transition Event and
its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR (in which event no Interpolated Benchmark
with respect to Three-Month Term SOFR shall be determined), then “Benchmark Replacement” means the first alternative
set forth in the order below that can be determined by the Calculation Agent as of the Benchmark Replacement Date:

 

	 	(1)	Compounded SOFR;

 

	 	(2)	the sum of (a) the alternate rate that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark for the applicable Corresponding Tenor and (b) the Benchmark Replacement Adjustment;

 

	 	(3)	the sum of (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; and

 

	 	(4)	the sum of (a) the alternate rate that has been selected by the Calculation Agent as the replacement for the then-current Benchmark for the applicable Corresponding Tenor, giving due consideration to any industry-accepted rate as a replacement for the then-current Benchmark for U.S. dollar-denominated floating rate securities at such time, and (b) the Benchmark Replacement Adjustment.

 

“Benchmark
Replacement Adjustment” means the first alternative set forth in the order below that can be determined by the Calculation
Agent as of the Benchmark Replacement Date:

 

	 	(1)	the spread adjustment, or method for calculating or determining such spread adjustment (which may be a positive or negative value or zero), that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement;

 

	 	(2)	if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, then the ISDA Fallback Adjustment; and

 

	 	(3)	the spread adjustment (which may be a positive or negative value or zero) that has been selected by the Calculation Agent, giving due consideration to any industry-accepted spread adjustment or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar-denominated floating rate securities at such time.

 

“Benchmark
Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational
changes (including changes to the definition of “Interest Period”, timing and frequency of determining rates with respect
to each Interest Period and making payments of interest, rounding of amounts or tenors, and other administrative matters) that
the Calculation Agent determines may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially
consistent with market practice (or, if the Calculation Agent determines that adoption of any portion of such market practice is
not administratively feasible or if the Calculation Agent determines that no market practice for use of the Benchmark Replacement
exists, in such other manner as the Calculation Agent determines is reasonably necessary).

 

    2

     

    

 

“Benchmark
Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark:

 

	 	(1)	in the case of clause (1) of the definition of “Benchmark Transition Event,” the relevant Reference Time in respect of any determination;

 

	 	(2)	in the case of clause (2) or (3) of the definition of “Benchmark Transition Event,” the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark; or

 

	 	(3)	in the case of clause (4) of the definition of “Benchmark Transition Event,” the date of the public statement or publication of information referenced therein.

 

For the avoidance of doubt, if the event
giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any
determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

 

“Benchmark
Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark:

 

	 	(1)	if the Benchmark is Three-Month Term SOFR, (a) the Relevant Governmental Body has not selected or recommended a forward-looking term rate for a tenor of three months based on SOFR, (b) the development of a forward-looking term rate for a tenor of three months based on SOFR that has been recommended or selected by the Relevant Governmental Body is not complete or (c) the Company determines that the use of a forward-looking rate for a tenor of three months based on SOFR is not administratively feasible;

 

	 	(2)	a public statement or publication of information by or on behalf of the administrator of the Benchmark announcing that such administrator has ceased or will cease to provide the Benchmark, permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark;

 

	 	(3)	a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark, the central bank for the currency of the Benchmark, an insolvency official with jurisdiction over the administrator for the Benchmark, a resolution authority with jurisdiction over the administrator for the Benchmark or a court or an entity with similar insolvency or resolution authority over the administrator for the Benchmark, which states that the administrator of the Benchmark has ceased or will cease to provide the Benchmark permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark; or

 

	 	(4)	a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative.

 

“Business
Day” means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions
in the City of New York or any place of payment are authorized or required by law, regulation or executive order to close.

 

“Calculation
Agent” means the agent appointed by the Company prior to the commencement of the Floating Rate Period (which may be the
Company or any of its Affiliates) to act in accordance with Section 3.02(e)(iv). The Trustee shall not be the Calculation Agent.

 

“Compounded
SOFR” means the compounded average of SOFRs for the applicable Corresponding Tenor, with the rate, or methodology for
this rate, and conventions for this rate being established by the Calculation Agent in accordance with:

 

	 	(1)	the rate, or methodology for this rate, and conventions for this rate selected or recommended by the Relevant Governmental Body for determining compounded SOFR; provided that:

 

	 	(2)	if, and to the extent that, the Calculation Agent determines that Compounded SOFR cannot be determined in accordance with clause (1) above, then the rate, or methodology for this rate, and conventions for this rate that have been selected by the Calculation Agent giving due consideration to any industry-accepted market practice for U.S. dollar-denominated floating rate securities at such time.

 

    3

     

    

 

For the avoidance of doubt, the calculation
of Compounded SOFR shall exclude the Benchmark Replacement Adjustment and the spread specified in Section 3.02(e)(ii).

 

“Corresponding
Tenor” means (i) with respect to Term SOFR, three months, and (ii) with respect to a Benchmark Replacement, a tenor (including
overnight) having approximately the same length (disregarding business day adjustment) as the applicable tenor for the then-current
Benchmark.

Senior Indebtedness.

 

“Federal Reserve”
means the Board of Governors of the Federal Reserve System or any successor federal banking agency.

 

“Federal Reserve
Bank of New York’s Website” means the website of the Federal Reserve Bank of New York at http://www.newyorkfed.org,

payables in the ordinary course of business; and (z) the Notes. Notwithstanding the foregoing, and for the avoidance of doubt,
if the Federal Reserve (or other applicable regulatory agency or authority) promulgates any rule or issues any interpretation that
defines general creditor(s), the main purpose of which is to establish criteria for determining whether the subordinated debt of
a financial or bank holding company is to be included in its capital, then the term “general creditors” as used in
this definition of “Senior Indebtedness” will have the meaning as described in that rule or interpretation.

“SOFR”
means the secured overnight financing rate published by the Federal Reserve Bank of New York, as the administrator of the Benchmark
(or any successor administrator), on the Federal Reserve Bank of New York’s Website.

 

“Tax Event”
means the receipt by the Company of an opinion of independent tax counsel to the effect that as a result of (1) an amendment to
or change (including any announced prospective amendment or change) in any law or treaty, or any regulation thereunder, of the
United States or any of its political subdivisions or taxing authorities; (2) a judicial decision, administrative action, official
administrative pronouncement, ruling, regulatory procedure, regulation, notice or announcement, including any notice or announcement
of intent to adopt or promulgate any ruling, regulatory procedure or regulation (any of the foregoing, an “Administrative
or Judicial Action”); or (3) an amendment to or change in any official position with respect to, or any interpretation
of, an Administrative or Judicial Action or a law or regulation of the United States that differs from the previously generally
accepted position or interpretation, in each case, which change or amendment or challenge becomes effective or which pronouncement,
decision or challenge is announced on or after the Issue Date, there is more than an insubstantial risk that 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.

 

“Term SOFR”
means the forward-looking term rate for the applicable Corresponding Tenor based on SOFR that has been selected or recommended
by the Relevant Governmental Body.

 

“Term SOFR
Administrator” means any entity designated by the Relevant Governmental Body as the administrator of Term SOFR (or any
successor administrator).

 

“Three-Month
Term SOFR” means Term SOFR for a tenor of three months that is published by the Term SOFR Administrator at the Reference
Time for any Interest Period, as determined by the Calculation Agent after giving effect to the Three-Month Term SOFR Conventions.
All percentages used in or resulting from any calculation of Three-Month Term SOFR shall be rounded, if necessary, to the nearest
one-hundred-thousandth of a percentage point, with 0.000005% rounded up to 0.00001%.

 

“Three-Month
Term SOFR Conventions” means any determination, decision or election with respect to any technical, administrative or
operational matter (including with respect to the manner and timing of the publication of Three-Month Term SOFR, or changes to
the definition of “Interest Period”, timing and frequency of determining Three-Month Term SOFR with respect to each
Interest Period and making payments of interest, rounding of amounts or tenors, and other administrative matters) that the Calculation
Agent determines may be appropriate to reflect the use of Three-Month Term SOFR as the Benchmark in a manner substantially consistent
with market practice (or, if the Calculation Agent determines that adoption of any portion of such market practice is not administratively
feasible or if the Calculation Agent determines that no market practice for the use of Three-Month Term SOFR exists, in such other
manner as the Calculation Agent determines is reasonably necessary).

 

“Tier 2 Capital
Event” means the Company’s good faith determination that, as a result of (1) any amendment to, or change in, the
laws, rules or regulations of the United States (including, for the avoidance of doubt, any agency or instrumentality of the United
States, including the Federal Reserve and other federal bank regulatory agencies) or any political subdivision of or in the United
States that is enacted or becomes effective after the Issue Date, (2) any proposed change in those laws, rules or regulations that
is announced or becomes effective after the Issue Date, or (3) any official administrative decision or judicial decision or administrative
action or other official pronouncement interpreting or applying those laws, rules, regulations, policies or guidelines with respect
thereto that is announced after the Issue Date, there is more than an insubstantial risk that the Company will not be entitled
to treat the Notes then outstanding as “Tier 2 Capital” (or its equivalent), for purposes of the capital adequacy rules
or regulations of the Federal Reserve as then in effect and applicable to the Company, for so long as any Notes are outstanding.

 

“Unadjusted
Benchmark Replacement” means the Benchmark Replacement excluding the Benchmark Replacement Adjustment.

ARTICLE III.

 

FORM AND TERMS OF THE NOTES

 

Section 3.01 Form and Dating.

 

(a) The Notes shall
be substantially in the form of Exhibit A attached hereto. The Notes shall be executed on behalf of the Company by its Chair
of the Board, its Vice Chair of the Board, its President and Chief Executive Officer, its Chief Financial Officer or one of its
Executive Vice Presidents.

 

(b) The terms contained
in the Notes shall constitute, and are hereby expressly made, a part of the Base Indenture as supplemented by this Supplemental
Indenture, and the Company and the Trustee, by their execution and delivery of this Supplemental Indenture, expressly agree to
such terms and provisions and to be bound thereby.

 

Section 3.02 Terms. The following
terms relating to the Notes are hereby established:

 

(a) Title. The
Notes shall constitute a series of Securities having the title “5.25% Fixed-to-Floating Rate Subordinated Notes due 2030”
and the CUSIP number 32055Y AA0.

 

(b) Principal Amount.
The aggregate principal amount of the Notes that may be authenticated and delivered under the Indenture on the Issue Date shall
be ONE HUNDRED MILLION DOLLARS ($100,000,000). If no Event of Default has occurred and is continuing with respect to the Notes,
the Company may, from time to time, without notice to or the consent of the Holders, create and issue additional notes (“Additional
Notes”) pursuant to the Indenture ranking equally with the Notes and with identical terms in all respects (or in all
respects except for the offering price, the payment of interest accruing prior to the issue date of such Additional Notes and the
first payment of interest following the issue date of such Additional Notes); provided, however, that a separate
CUSIP number will be issued for any such Additional Notes unless such Additional Notes are fungible with the Notes for U.S. federal
income tax purposes, subject to the procedures of DTC. The Notes and any Additional Notes shall constitute a single series under
the Indenture. All references to the Notes shall include any Additional Notes, unless the context otherwise requires.

 

(c) Person to Whom
Interest Is Payable. Defaulted Interest may be paid as provided in Section 307 of the Base Indenture. However, interest that
is paid on the Maturity Date will be paid to the Person to whom the principal is payable.

 

(d) Maturity Date.
The entire outstanding Principal of the Notes shall be payable on May 15, 2030 (the “Maturity Date”).

 

(e) Interest.

 

(i) The Notes will bear
interest at a fixed rate of 5.25% per annum from and including May 15, 2020, to but excluding May 15, 2025, or earlier Redemption
Date (the “Fixed Rate Period”). Interest accrued on the Notes during the Fixed Rate Period will be payable semi-annually
in arrears on May 15 and November 15 of each year, commencing on November 15, 2020 (each such date, a “Fixed Rate Interest
Payment Date”). The last Fixed Rate Interest Payment Date shall be May 15, 2025, unless the Notes are earlier redeemed.
The interest payable during the Fixed Rate Period will be paid to each Holder in whose name a Note is registered at the close of
business on the fifteenth day (whether or not a Business Day) immediately preceding the applicable Fixed Rate Interest Payment
Date.

 

(ii) The Notes will bear
a floating interest rate from and including May 15, 2025, to but excluding the Maturity Date or earlier Redemption Date (the “Floating
Rate Period”). The floating interest rate will be reset for each Interest Period in the Floating Rate Period, and the
interest rate for each such Interest Period shall be equal to the then-current Three-Month Term SOFR for such Interest Period plus
518 basis points, provided that if Three-Month Term SOFR (or other applicable Benchmark) is less than zero for any Interest
Period during the Floating Rate Period, then Three-Month Term SOFR (or other such Benchmark) shall be deemed to be zero for such
Interest Period. During the Floating Rate Period, interest on the Notes will be payable quarterly in arrears on February 15, May
15, August 15 and November 15 of each year, commencing on August 15, 2025 (each such date, a “Floating Rate Interest Payment
Date” and, together with each Fixed Rate Interest Payment Date, each an “Interest Payment Date”).
The last Floating Rate Interest Payment Date shall be May 15, 2030, unless the Notes are earlier redeemed. The interest payable
during the Floating Rate Period will be paid to each Holder in whose name a Note is registered at the close of business on the
fifteenth day (whether or not a Business Day) immediately preceding the applicable Floating Rate Interest Payment Date. The Calculation
Agent will provide the Company and the Trustee with the interest rate in effect for each Interest Period during the Floating Rate
Period promptly after the Reference Time therefor (or other date of determination for the applicable Benchmark).

 

(iii) The amount of interest
payable on any Fixed Rate Interest Payment Date during the Fixed Rate Period will be computed on the basis of a 360-day year consisting
of twelve 30-day months, and the amount of interest payable on any Floating Rate Interest Payment Date during the Floating Rate
Period will be computed on the basis of a 360-day year and the actual number of days elapsed. In the event that any scheduled Interest
Payment Date or the Maturity Date for the Notes falls on a day that is not a Business Day, then payment shall be made as provided
in Section 113 of the Base Indenture; provided, that if any scheduled Floating Rate Interest Payment Date falls on a day
that is not a Business Day and the next succeeding Business Day falls in the next succeeding calendar month, such Floating Rate
Interest Payment Date will be accelerated to the immediately preceding Business Day, and, in each such case, the amounts payable
on such Business Day will include interest accrued to, but excluding such Business Day. Dollar amounts resulting from interest
calculations will be rounded to the nearest cent, with one-half cent being rounded upward.

 

    7

     

    

 

(iv) The Company shall
take such actions as are necessary to ensure that from the commencement of the Floating Rate Period for so long as any of the Notes
remain outstanding there will at all times be a Calculation Agent appointed to calculate Three-Month Term SOFR in respect of each
Floating Rate Period. The calculation of Three-Month Term SOFR for each applicable Floating Rate Period by the Calculation Agent
will (in the absence of manifest error) be final and binding. The Calculation Agent shall have all the rights, protections and
indemnities afforded to the Trustee under the Base Indenture and hereunder. The Calculation Agent may be removed by the Company
at any time. If the Calculation Agent is unable or unwilling to act as Calculation Agent or is removed by the Company, the Company
will promptly appoint a replacement Calculation Agent, which shall not be the Trustee. The Calculation Agent may not resign its
duties without a successor having been duly appointed; provided, that if a successor Calculation Agent has not been appointed
by the Company and such successor accepted such position within 30 days after the giving of notice of resignation by the Calculation
Agent, then the resigning Calculation Agent may petition, at the expense of the Company, any court of competent jurisdiction for
the appointment of a successor Calculation Agent with respect to such series. For the avoidance of doubt, if at any time there
is no Calculation Agent appointed by the Company, then the Company shall be the Calculation Agent. The Company may appoint itself
or any of its Affiliates to be the Calculation Agent.

 

(v) Effect of Benchmark
Transition Event and Benchmark Replacement Date.

 

(1) If the Calculation
Agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred on or prior to the
Reference Time in respect of any Interest Period during the Floating Rate Period, then the Benchmark Replacement will replace the
then-current Benchmark for all purposes relating to the Notes during such Interest Period and all subsequent Interest Periods.

 

(2) Notwithstanding
anything set forth in clause (ii) above, if the Calculation Agent determines that a Benchmark Transition Event and its related
Benchmark Replacement Date have occurred on or prior to the relevant Reference Time with respect to Three-Month Term SOFR, then
the provisions set forth in this clause (v) will thereafter apply to all determinations of the rate or interest payable on the
Notes during the Floating Rate Period. After a Benchmark Transition Event and its related Benchmark Replacement Date have occurred,
the interest rate on the Notes for each Interest Period during the Floating Rate Period will be an annual rate equal to the Benchmark
Replacement plus the spread specified in clause (ii) above.

 

(3) The Company and
the Calculation Agent are expressly authorized to make determinations, decisions and elections under the terms of the Notes, including
with respect to the use of any Benchmark Replacement for the Floating Rate Period and under this clause (v). Any determination,
decision or election that may be made by the Company or by the Calculation Agent under the terms of the Notes, including any determination
with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision
to take or refrain from taking any action or selection (A) will be conclusive and binding on the Holders and the Trustee absent
manifest error, (B) if made by the Company, will be made in the Company’s sole discretion, (C) if made by the Calculation
Agent, will be made after consultation with the Company, and the Calculation Agent will not make any such determination, decision
or election to which the Company reasonably objects, and (D) notwithstanding anything to the contrary herein or in the Base Indenture,
shall become effective without consent from the Holders or the Trustee. If the Calculation Agent fails to make any determination,
decision or election that it is required to make under the terms of the Notes, then the Company will make such determination, decision
or election on the same basis as described above.

 

(vi) The Company (or
its Calculation Agent) shall notify the Trustee in writing (1) upon the occurrence of the Benchmark Transition Event or the Benchmark
Replacement Date, and (2) of any Benchmark Replacements, Benchmark Replacement Conforming Changes and other items affecting the
interest rate on the Notes after a Benchmark Transition Event.

 

(vii) The Trustee (including
in its capacity as Paying Agent) shall have no (1) responsibility or liability for (A) Three-Month Term SOFR Conventions, (B) selection
of an alternative reference rate to Three-Month Term SOFR (including whether the conditions for the designation of such rate have
been satisfied or whether such rate is a Benchmark Replacement or an Unadjusted Benchmark Replacement), (C) determination or calculation
of a Benchmark Replacement, or (D) determination of whether a Benchmark Transition Event or Benchmark Replacement Date has occurred,
and in each such case under clauses (A) through (D) above shall be entitled to conclusively rely upon the selection, determination,
and/or calculation thereof as provided by the Company or its Calculation Agent, as applicable, or (2) liability for any failure
or delay in performing its duties hereunder as a result of the unavailability of a Benchmark as described in the definition thereof,
including as a result of the Company’s or Calculation Agent’s failure to select a Benchmark Replacement or the Calculation
Agent’s failure to calculate a Benchmark. The Trustee shall be entitled to rely conclusively on all notices from the Company
or its Calculation Agent regarding any Benchmark or Benchmark Replacement, including in regards to Three-Month Term SOFR Conventions,
a Benchmark Transition Event, Benchmark Replacement Date, and Benchmark Replacement Conforming Changes.

 

    8

     

    

 

(viii) If the then-current
Benchmark is Three-Month Term SOFR and any of the foregoing provisions concerning the calculation of the interest rate and the
payment of interest during the Floating Rate Period are inconsistent with any of the Three-Month Term SOFR Conventions determined
by the Calculation Agent, then the relevant Three-Month Term SOFR Conventions will apply.

 

(f) Place of Payment
of Principal and Interest. So long as the Notes are issued in the form of one or more Global Securities, the Company shall
make, or cause the Paying Agent to make, all payments of principal and interest on the Notes by wire transfer in immediately available
funds to DTC or its nominee, in accordance with applicable procedures of DTC. If the Notes are not so issued, the Company may,
at its option, make, or cause the Paying Agent to make, payments of principal and interest on the Notes by check mailed to the
address of the Holder specified in accordance with Sections 3.02(e)(i) or (e)(ii).

 

(g) Redemption.
The Notes are not subject to redemption or prepayment at the option of the Holders.

 

The Notes shall be
redeemable at the option of the Company, in whole or in part from time to time, beginning with the Interest Payment Date on May
15, 2025, and on any Interest Payment Date thereafter, subject to obtaining the prior approval of the Federal Reserve to the extent
such approval is then required under the rules of the Federal Reserve.

 

In addition, the Company
may, at its option, redeem the Notes at any time before the Maturity Date, in whole but not in part, subject to obtaining the prior
approval of the Federal Reserve to the extent such approval is then required under the rules of the Federal Reserve, 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, as amended (15 U.S.C. 80a-1 et seq.).

 

The Notes may not otherwise
be redeemed prior to the Maturity Date.

 

The Redemption Price
shall equal 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest to, but excluding,
the Redemption Date fixed by the Company. The provisions of Article XI of the Base Indenture shall apply to any redemption of the
Notes. Any partial redemption will be made in accordance with DTC’s applicable procedures among all Holders. If any Note
is to be redeemed in part only, the notice of redemption relating to such Note shall state, in addition to the information specified
in Section 1104 of the Base Indenture, that such redemption is a partial redemption, the portion of the principal amount thereof
to be redeemed, and that a replacement Note in principal amount equal to the unredeemed portion thereof will be issued in the name
of the Holder thereof upon cancellation of the original Note.

 

Any notice of redemption
may be conditional in the Company’s discretion on one or more conditions precedent, and the Redemption Date may be delayed
until such time as any or all of such conditions have been satisfied or revoked by the Company if it determines that such conditions
will not be satisfied.

 

(h) Sinking Fund.
There shall be no sinking fund for the Notes.

 

(i) Conversion and
Exchange. The Notes are not convertible into, or exchangeable for, equity securities, other securities or assets of the Company
or its Subsidiaries.

 

(j) Denomination.
The Notes and any beneficial interest in the Notes shall be in minimum denominations of $1,000 and integral multiples of $1,000
in excess thereof.

 

(k) Currency of
the Notes. The Notes shall be denominated, and the principal thereof and interest thereon shall be payable, in Dollars.

 

    9

     

    

 

(l) Registered Form.
The Notes shall be issuable as Global Securities, and DTC (or any successor thereto or successor depositary appointed by the Company
within 90 days of the termination of services of DTC) shall be the depositary for the Notes. Sections 304 and 307 of the Base Indenture
shall apply to the Notes.

 

(m) Events of Default.
The Events of Default provided for in Section 501 of the Base Indenture shall apply to the Notes, provided that clause (6)
thereof shall be deleted in its entirety and the following shall be inserted in lieu thereof (and shall constitute “Events
of Default”):

 

“(6) appointment of a Custodian
for the Material Subsidiary; or

 

(7) the Company pursuant to or
within the meaning of any Bankruptcy Law generally is unable to pay its debts as the same become due.”

 

(n) Acceleration
of Maturity. Section 502 of the Base Indenture shall apply to the Notes, except that the first paragraph thereof shall be deleted
in its entirety and the following text inserted in lieu thereof:

 

“If
an Event of Default under clause (4), (5), (6) or (7) of Section 501 occurs and is continuing, then the principal amount of all
the Notes, together with accrued and unpaid interest, if any, thereon, shall automatically, and without any declaration or other
action on the part of the Trustee or any Holder, become immediately due and payable. The Maturity of the Notes shall not otherwise
be accelerated as a result of an Event of Default.”

 

In addition, the second
paragraph of Section 502 of the Base Indenture shall be amended by (i) deleting all occurrences of the text “declaration
of” appearing in such paragraph and (ii) deleting the text “declaration and” appearing in such paragraph and
inserting the text “acceleration and” in lieu thereof.

 

(o) Statement by
Officers as to Default. Section 1004 of the Base Indenture shall apply to the Notes, except the reference in that Section to
 “150 days” shall be replaced with “120 days.”

 

(p) No Collateral.
The Notes shall not be entitled to the benefit of any security interest in, or collateralization by, any rights, property or interest
of the Company.

 

(q) Satisfaction
and Discharge; Defeasance. Articles IV and XIII of the Base Indenture shall apply to the Notes.

 

(r) No Additional
Amounts. In the event that any payment on the Notes is subject to withholding of any U.S. federal income tax or other tax or
assessment (whether as a result of a change in law or otherwise), the Company will not pay additional amounts with respect to such
tax or assessment.

 

(s) Notices to Holders.
Any notices required to be given to Holders shall be given to a Responsible Officer of the Trustee. Notwithstanding any other provision
of the Indenture or any Note, where the Indenture or any Note provides for notice of any event or any other communication (including
any notice of redemption) to a Holder (whether by mail or otherwise), such notice shall be sufficiently given if given to DTC (or
its designee) pursuant to the applicable procedures from DTC or its designee, including by electronic mail in accordance with accepted
practices at DTC.

 

(t) Additional Terms.
Other terms applicable to the Notes are as otherwise provided for in the Base Indenture, as supplemented by this Supplemental Indenture,
including Articles IV and V hereof.

 

ARTICLE IV.

 

ADDITIONAL PROVISIONS

 

Section 4.01 Additional Provision.
Section 901 of the Base Indenture shall apply to the Notes, provided that the following text shall be inserted at the end
of such Section:

 

“Without
limitation of the foregoing, the Company and the Trustee may amend or supplement the Indenture or the Notes without the consent
of any Holder to implement any Three-Month Term SOFR Conventions or any benchmark transition provisions after a Benchmark Transition
Event and its related Benchmark Replacement Date have occurred (or in anticipation thereof). The Trustee may conclusively rely
on a Company Request (in addition to any other orders, certificates and opinions) as to whether a Benchmark Transition Event and
Benchmark Replacement Date have occurred.”

 

    10

     

    

 

ARTICLE V.

 

SUBORDINATION OF SECURITIES

 

Section 5.01 Agreement of Subordination.
The Company covenants and agrees, and each Holder by accepting a Note likewise covenants and agrees, that all Notes shall be issued
subject to the provisions of this Article; and each Person holding any Note, whether upon original issue or upon transfer, assignment
or exchange thereof, accepts and agrees to be bound by such provisions.

 

The payment of the
principal of, interest on and any Redemption Price for the Notes shall, to the extent and in the manner hereinafter set forth,
be subordinated and subject in right of payment to the prior payment in full of all Senior Indebtedness, whether outstanding at
the date of the Indenture or thereafter incurred.

 

No provision of this
Article shall prevent the occurrence of any Default or Event of Default hereunder.

 

Section 5.02 Payments to Holders.
No payment or distribution shall be made with respect to the principal of, interest on or any Redemption Price for the Notes, except
for payments and distributions made by the Trustee as permitted by the first or second paragraph of Section 5.05, if:

 

	 	(a)	(i) a default in the payment of principal, premium, interest or other obligations constituting Senior Indebtedness occurs and is continuing (or, in the case of Senior Indebtedness for which there is a period of grace, such a default occurs and continues beyond the period of grace specified in the instrument or lease evidencing such Senior Indebtedness), unless and until such default shall have been cured or waived or shall have ceased to exist, and (ii) a Responsible Officer of the Trustee receives a notice of such default from a Representative or the Company; or

 

	 	(b)	(i) a default under any Designated Senior Indebtedness (other than a default described in clause (a) above) occurs and is continuing, if the effect of such default is to permit holders of such Designated Senior Indebtedness to accelerate its maturity, and (ii) a Responsible Officer of the Trustee receives a notice of such default from a Representative or the Company (a “Payment Blockage Notice”).

 

Upon the Trustee’s
receipt of a Payment Blockage Notice, no subsequent Payment Blockage Notice shall be effective for purposes of this Section unless
and until (A) at least 365 days shall have elapsed since the initial effectiveness of the immediately prior Payment Blockage Notice
and (B) all scheduled payments of principal of, interest on and any Redemption Price for the Notes that have come due have been
paid in full in cash. No default described in clause (b) above that existed or was continuing on the date of delivery of any Payment
Blockage Notice shall be, or be made, the basis for a subsequent Payment Blockage Notice.

 

The Company may and
shall resume payments on and distributions in respect of the Notes upon the earlier of:

 

	 	(1)	the date upon which the default is cured or waived or ceases to exist, or

 

	 	(2)	in the case of a default described in clause (b) above, the 180th day after receipt of the corresponding Payment Blockage Notice, unless the maturity of such Designated Senior Indebtedness has been accelerated or this Article otherwise prohibits such payment or distribution at the time thereof.

 

Upon any payment by
the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or Notes, to creditors
upon any dissolution or winding-up or liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy,
insolvency, receivership or other proceedings, all amounts due or to become due upon all Senior Indebtedness shall first be paid
in full in cash or other payment satisfactory to the holders of such Senior Indebtedness, or payment thereof in accordance with
its terms provided for in cash or other payment satisfactory to the holders of such Senior Indebtedness, before any payment is
made on account of the principal of or interest on the Notes (except payments made pursuant to Article V of the Base Indenture
from monies deposited with the Trustee pursuant thereto prior to commencement of proceedings for such dissolution, winding-up,
liquidation or reorganization); and upon any such dissolution or winding-up or liquidation or reorganization of the Company or
bankruptcy, insolvency, receivership or other proceeding, any payment by the Company, or distribution of assets of the Company
of any kind or character, whether in cash, property or Notes, to which the Holders or the Trustee would be entitled, except for
the provision of this Article, shall (except as aforesaid) be paid by the Company or by any receiver, trustee in bankruptcy, liquidating
trustee, agent or other Person making such payment or distribution, or by the Holders or by the Trustee under the Indenture if
received by them or it, directly to the holders of Senior Indebtedness (pro rata to such holders on the basis of the respective
amounts of Senior Indebtedness held by such holders, or as otherwise required by law or a court order) or to their Representative,
as their respective interests may appear, to the extent necessary to pay all Senior Indebtedness in full, in cash or other payment
satisfactory to the holders of such Senior Indebtedness, after giving effect to any concurrent payment or distribution to or for
the holders of Senior Indebtedness, before any payment or distribution or provision therefor is made to the Holders or to the Trustee.
Whenever a distribution is to be made or a notice given to the holders of Senior Indebtedness, the distribution may be made and
the notice given to their Representative.

 

    11

     

    

 

For purposes of this
Article, the words, “cash, property or Notes” shall not be deemed to include shares of stock of the Company
as reorganized or readjusted, or Notes of the Company or any other Person provided for by a plan of reorganization or readjustment,
the payment of which is subordinated at least to the extent provided in this Article with respect to the Notes to the payment of
all Senior Indebtedness which may at the time be outstanding; provided that (i) the Senior Indebtedness is assumed by the
new Person, if any, resulting from any reorganization or readjustment, and (ii) the rights of the holders of Senior Indebtedness
(other than leases which are not assumed by the Company or the new Person, as the case may be) are not, without the consent of
such holders, altered by such reorganization or readjustment.

 

The consolidation of
the Company with, or the merger of the Company into, another Person, or the liquidation or dissolution of the Company following
the conveyance or transfer of its property as an entirety, or substantially as an entirety, to another Person upon the terms and
conditions provided for in Article VIII of the Base Indenture shall not be deemed a dissolution, winding-up, liquidation or reorganization
for the purposes of this Section if such other Person shall, as a part of such consolidation, merger, conveyance or transfer, comply
with the conditions stated in Article VIII of the Base Indenture.

 

In the event of the
acceleration of the Notes because of an Event of Default, no payment or distribution shall be made to the Trustee or any Holder
in respect of the principal of or interest on the Notes (including, but not limited to, the Redemption Price with respect to the
Notes called for redemption in accordance with Section 3.02(g)), except payments and distributions made by the Trustee as permitted
by the first or second paragraph of Section 5.05, until all Senior Indebtedness has been paid in full in cash or other payment
satisfactory to the holders of Senior Indebtedness or such acceleration is rescinded in accordance with the terms of the Indenture.
If payment of the Notes is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Indebtedness
of the acceleration at the address set forth in the notice from the Representative to the Trustee as being the address to which
the Trustee should send its notice pursuant to this Section, unless there are no payment obligations of the Company thereunder
and all obligations thereunder to extend credit have been terminated or expired.

 

In the event that,
notwithstanding the foregoing provisions, any payment or distribution of assets of the Company of any kind or character, whether
in cash, property or Notes (including by way of setoff or otherwise), prohibited by the foregoing, shall be received by the Trustee
or the Holders before all Senior Indebtedness is paid in full in cash or other payment satisfactory to the holders of such Senior
Indebtedness, or provision is made for such payment thereof in accordance with its terms in cash or other payment satisfactory
to the holders of such Senior Indebtedness, such payment or distribution shall be held in trust for the benefit of and shall be
paid over or delivered to the holders of Senior Indebtedness or their Representative, as their respective interests may appear,
as calculated by the Company and directed by the Company pursuant to a Company Order, for application to the payment of all Senior
Indebtedness remaining unpaid to the extent necessary to pay all Senior Indebtedness in full in cash or other payment satisfactory
to the holders of such Senior Indebtedness, after giving effect to any concurrent payment or distribution to or for the holders
of such Senior Indebtedness.

 

Nothing in this Article
shall apply to claims of, or payments to, the Trustee under or pursuant to Section 607 of the Base Indenture. This Section shall
be subject to the further provisions of Section 5.05. For the avoidance of doubt, such payments are not subordinated to the Company’s
Senior Indebtedness.

 

Section 5.03 Subrogation of Notes.
Subject to the payment in full of all Senior Indebtedness, the rights of the Holders shall be subrogated to the extent of the payments
or distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article (equally and ratably
with the holders of all indebtedness of the Company which by its express terms is subordinated to other indebtedness of the Company
to substantially the same extent as the Notes are subordinated and is entitled to like rights of subrogation) to the rights of
the holders of Senior Indebtedness to receive payments or distributions of cash, property or Notes of the Company applicable to
the Senior Indebtedness until the principal and interest on the Notes shall be paid in full; and, for the purposes of such subrogation,
no payments or distributions to the holders of the Senior Indebtedness of any cash, property or Notes to which the Holders or the
Trustee would be entitled except for the provisions of this Article, and no payment over pursuant to the provisions of this Article,
to or for the benefit of the holders of Senior Indebtedness by Holders or the Trustee, shall, as between the Company, its creditors
other than holders of Senior Indebtedness, and the Holders, be deemed to be a payment by the Company to or on account of the Senior
Indebtedness; and no payments or distributions of cash, property or Notes to or for the benefit of the Holders pursuant to the
subrogation provisions of this Article, which would otherwise have been paid to the holders of Senior Indebtedness shall be deemed
to be a payment by the Company to or for the account of the Notes. It is understood that the provisions of this Article are and
are intended solely for the purposes of defining the relative rights of the Holders, on the one hand, and the holders of the Senior
Indebtedness, on the other hand.

 

    12

     

    

 

Nothing contained in
this Article or elsewhere in the Indenture or in the Notes is intended to or shall impair, as among the Company, its creditors
other than the holders of Senior Indebtedness, and the Holders, the obligation of the Company, which is absolute and unconditional,
to pay to the Holders the principal of and interest on the Notes as and when the same shall become due and payable in accordance
with their terms, or is intended to or shall affect the relative rights of the Holders and creditors of the Company other than
the holders of the Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or the Holder of any Note from
exercising all remedies otherwise permitted by applicable law upon default under the Indenture, subject to the rights, if any,
under this Article of the holders of Senior Indebtedness in respect of cash, property or Notes of the Company received upon the
exercise of any such remedy.

 

Upon any payment or
distribution of assets of the Company referred to in this Article, the Trustee, subject to the provisions of Section 601 of the
Base Indenture, and the Holders shall be entitled to conclusively rely upon any order or decree made by any court of competent
jurisdiction in which such bankruptcy, dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate
of the receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, delivered
to the Trustee or to the Holders, for the purpose of ascertaining the Persons entitled to participate in such distribution, the
holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon and all other facts
pertinent thereto or to this Article.

 

Section 5.04 Authorization to Effect
Subordination. Each Holder of a Note, by the acceptance thereof, authorizes and directs the Trustee on the Holder’s behalf
to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article and appoints
the Trustee to act as the Holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper
proof of claim or proof of debt in the form required in any proceeding referred to in Section 504 of the Base Indenture hereof
at least 30 days before the expiration of the time to file such claim, the holders of any Senior Indebtedness or their representatives
are hereby authorized to file an appropriate claim for and on behalf of the Holders.

 

Section 5.05 Notice to Trustee.
The Company shall give prompt written notice to a Responsible Officer of the Trustee and to any paying agent of any fact known
to the Company which would prohibit the making of any payment of monies to or by the Trustee or any Paying Agent pursuant to the
provisions of this Article. Notwithstanding the provisions of this Article or any other provision of the Indenture, the Trustee
shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment of monies to or
by the Trustee in respect of the Notes pursuant to the provisions of this Article, unless and until a Responsible Officer of the
Trustee shall have received written notice thereof at the Corporate Trust Office from the Company or a Representative; and before
the receipt of any such written notice, the Trustee, subject to Section 601 of the Base Indenture, shall be entitled in all respects
to assume that no such facts exist; provided that if on a date not fewer than two Business Days prior to the date upon which
by the terms hereof any such monies may become payable for any purpose (including the payment of the principal of or interest on
any Note) the Trustee shall not have received, with respect to such monies, the notice provided for in this Section, then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such monies and to
apply the same to the purpose for which they were received, and shall not be affected by any notice to the contrary which may be
received by it on or after such prior date.

 

Notwithstanding anything
in this Article to the contrary, nothing shall prevent any payment by the Trustee to the Holders of monies deposited with it pursuant
to Section 401 of the Base Indenture, and any such payment shall not be subject to the provisions of Section 5.01 or 5.02.

 

The Trustee, subject
to the provisions of Section 601 of the Base Indenture, shall be entitled to rely on the delivery to it of a written notice by
a Representative or a Person representing himself to be a holder of Senior Indebtedness (or a trustee on behalf of such holder)
to establish that such notice has been given by a Representative or a holder of Senior Indebtedness or a trustee on behalf of any
such holder or holders. In the event that the Trustee determines in good faith that further evidence is required with respect to
the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article,
the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior
Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and
any other facts pertinent to the rights of such Person under this Article, and if such evidence is not furnished the Trustee may
defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment.

 

    13

     

    

 

Section 5.06 Trustee’s Relation
to Senior Indebtedness. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article
in respect of any Senior Indebtedness at any time held by it, to the same extent as any other holder of Senior Indebtedness, and
nothing in Section 613 of the Base Indenture or elsewhere in the Indenture shall deprive the Trustee of any of its rights as such
holder. Nothing in this Article shall apply to the Company’s obligations to the Trustee under Section 607 of the Base Indenture.

 

With respect to the
holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article, and no implied covenants or obligations with respect to the holders of Senior Indebtedness
shall be read into the Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders
of Senior Indebtedness and, subject to the provisions of Section 601 of the Base Indenture, the Trustee shall not be liable to
any holder of Senior Indebtedness if it shall pay over or deliver to Holders, the Company or any other Person money or assets to
which any holder of Senior Indebtedness shall be entitled by virtue of this Article or otherwise.

 

Section 5.07 No Impairment of Subordination.
No right of any present or future holder of any Senior Indebtedness to enforce subordination as herein provided shall at any time
in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in
good faith, by any such holder, or by any noncompliance by the Company with the terms, provisions and covenants of the Indenture,
regardless of any knowledge thereof which any such holder may have or otherwise be charged with.

 

Section 5.08 Article Applicable to Paying
Agents. If at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting
hereunder, the term “Trustee” as used in this Article shall (unless the context otherwise requires) be construed as
extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article in addition to or in place of the Trustee; provided, however, that the first paragraph of Section
5.05 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent.

 

Section 5.09 Senior Indebtedness Entitled
to Rely. The holders of Senior Indebtedness (including Designated Senior Indebtedness) shall have the right to rely upon this
Article, and no amendment or modification of the provisions contained herein shall diminish the rights of such holders unless such
holders shall have agreed in writing thereto.

FIRST INTERSTATE BANCSYSTEM,
INC., a Montana corporation (together with any successor Corporation under the Indenture hereinafter referred to, the “Company”),
for value received, hereby promises to pay to CEDE & CO., or its registered assigns, the principal sum of ONE HUNDRED MILLION
DOLLARS ($100,000,000) on May 15, 2030 (the “Stated Maturity Date”), unless redeemed prior to such date, and
to pay interest thereon (i) from and including May 15, 2020, to but excluding May 15, 2025, unless redeemed prior to such date
(such period, the “Fixed Rate Period”), at a rate of 5.25% per annum, semi-annually in arrears on May 15 and
November 15 of each year, commencing on November 15, 2020 (each such date, a “Fixed Rate Interest Payment Date”)
and (ii) from and including May 15, 2025, to but excluding the Stated Maturity Date, unless redeemed on or subsequent to May 15,
2025, but prior to the Stated Maturity Date (such period, the “Floating Rate Period”), at a rate equal to Three-Month
Term SOFR, reset quarterly, plus 518.0 basis points, or such other rate as may be determined pursuant to the Supplemental
Indenture hereinafter referred to, quarterly in arrears on February 15, May 15, August 15 and November 15 of each year, commencing
on August 15, 2025, and ending on the Stated Maturity Date or earlier Redemption Date (each such date, a “Floating Rate
Interest Payment Date” and, together with each Fixed Rate Interest Payment Date, each an “Interest Payment Date”).
The amount of interest payable on any Fixed Rate Interest Payment Date during the Fixed Rate Period will be computed on the basis
of a 360-day year consisting of twelve 30-day months, and the amount of interest payable on any Floating Rate Interest Payment
Date during the Floating Rate Period will be computed on the basis of a 360-day year and the actual number of days elapsed. If
any Interest Payment Date or the Stated Maturity Date falls on a day that is not a Business Day, payment may be made on the next
succeeding Business Day and no interest on such payment will accrue for the period of such delay; provided that if any scheduled
Floating Rate Interest Payment Date falls on a day that is not a Business Day and the next succeeding Business Day falls in the
next succeeding calendar month, such Floating Rate Interest Payment Date will be accelerated to the immediately preceding Business
Day, and in each such case the amount payable on such Business Day will include interest accrued to but excluding such Business
Day. All percentages used in or resulting from any calculation of Three-Month Term SOFR shall be rounded, if necessary, to the
nearest one hundred-thousandth of a percentage point, with 0.000005% rounded up to 0.00001%.

 

Payment of the principal
of and interest on this Note will be made 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.

 

Reference is hereby
made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have
the same effect as if set forth at this place.

REVERSE OF NOTE

 

FIRST INTERSTATE BANCSYSTEM, INC.

 

5.25% Fixed-to-Floating Rate Subordinated
Notes due 2030

 

This Note is one of
a duly authorized issue of Securities of the Company of a series designated as the “5.25% Fixed-to-Floating Rate Subordinated
Notes due 2030” (the “Notes”) initially issued in an aggregate principal amount of $100,000,000 on May
15, 2020. Such series of Securities has been established pursuant to, and is one of an indefinite number of series of subordinated
debt securities of the Company issued or issuable under and pursuant to the Subordinated Debt Securities Indenture dated as of
May 15, 2020 (the “Base Indenture” and, as the same may from time to time be amended, supplemented or otherwise
modified in accordance therewith, including by the Supplemental Indenture referred to below, the “Indenture”),
between the Company and U.S. Bank National Association, as Trustee (together with any successor trustee, the “Trustee”),
as supplemented and amended by the First Supplemental Indenture dated as of May 15, 2020, between the Company and the Trustee (the
 “Supplemental Indenture”), to which Indenture and any other indentures supplemental thereto reference is hereby
made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee
and the Persons in whose names Notes are registered from time to time and of the terms upon which the Notes are, and are to be,
authenticated and delivered. The terms, conditions and provisions of the Notes are those stated in the Indenture, those made part
of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), and
those set forth in this Note. To the extent that the provisions of this Note modify, supplement or are inconsistent with those
of the Indenture, then the provisions of this Note shall govern to the extent that such provisions of this Note are not inconsistent
with (i) the provisions of the Supplemental Indenture or (ii) the provisions made part of the Indenture by reference to the Trust
Indenture Act.

 

All capitalized terms
used in this Note and not defined herein that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

 

The indebtedness of
the Company evidenced by the Notes, including the principal thereof and interest thereon, (i) to the extent and in the manner set
forth in the Indenture, is subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness,
whether outstanding at the date hereof or hereafter incurred, on the terms and subject to the terms and conditions set forth in
the Indenture, and (ii) shall rank pari passu in right of payment with all other Securities and with all other unsecured
subordinated indebtedness of the Company that is not by its terms subordinate and subject in right of payment to the prior payment
in full of debentures, notes, bonds or other evidences of indebtedness of types that include the Notes. Each Holder of this Note,
by the acceptance hereof, agrees to and shall be bound by such provisions of the Indenture and authorizes and directs the Trustee
on such Holder’s behalf to take such actions as may be necessary or appropriate to effectuate the subordination so provided.

 

The Notes are intended
to be treated as Tier 2 Capital (or its then-equivalent if the Company were subject to such capital requirement) for purposes of
capital adequacy rules or regulations of the Board of Governors of the Federal Reserve System (or any successor regulatory authority
with jurisdiction over bank holding companies) (the “Federal Reserve”) as applicable to the Company and as the
same may be amended or supplemented from time to time. If an Event of Default with respect to the Notes shall occur and be continuing,
the principal and interest owed on the Notes shall only become due and payable in accordance with the terms and conditions set
forth in Article V of the Base Indenture and Section 3.02(m) and (n) of the Supplemental Indenture. Accordingly, the Holder
has no right to accelerate the maturity of this Note in the event that the Company fails to pay interest on any of the Notes, or
fails to perform any other obligations under the Notes or in the Indenture that are applicable to the Notes.

 

The Company may, at
its option, redeem the Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to
be redeemed, plus accrued and unpaid interest (the “Redemption Price”) to, but excluding, the date of redemption
(the “Redemption Date”), on any Interest Payment Date on or after May 15, 2025. The Company may also, at its
option, redeem the Notes before the Stated Maturity Date, in whole, but not in part, at any 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, as amended. Any such redemption will be at a redemption price equal to the Redemption Price to, but excluding, the
Redemption Date fixed by the Company. No redemption of the Notes by the Company prior to the Stated Maturity Date shall be made
without the prior approval of the Federal Reserve if such prior approval is or will be required at the scheduled Redemption Date.
The provisions of Article XI of the Base Indenture and Section 3.02(g) of the Supplemental Indenture shall apply to the redemption
of any Notes by the Company.

 

    	 	A-5	 

     

    

 

 

The Notes are not entitled
to the benefit of any sinking fund. The Notes are not convertible into or exchangeable for any other securities or property of
the Company or any Subsidiary of the Company.

 

In the event that any
payment on the Notes is subject to withholding of any U.S. federal income tax or other tax or assessment (as a result of a change
in law or otherwise), the Company will not pay additional amounts with respect to such tax or assessment.

 

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 at any time by the Company and the Trustee with the consent of the Holders of at least a majority
in principal amount of the outstanding Notes. The Indenture also contains provisions permitting the Holders of specified percentages
in principal amount of the Notes at the time outstanding, on behalf of the Holders of all Notes, to waive compliance by the Company
with certain provisions of the Indenture and to waive certain past Defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this
Note and of any Note issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Note.

 

As provided in the
Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Securities Register
described in Section 305 of the Base Indenture, upon surrender of this Note for registration of transfer at the office or agency
of the Company in any place where the principal of and interest on this Note are payable, duly endorsed, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security Registrar and duly executed, by the Holder hereof or
its attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

 

The Notes are issuable
only in registered form without coupons in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof.

 

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

This Security is
a global note, represented by one or more permanent global certificates registered in the name of the nominee of The Depository
Trust Company (each a “Global Note” and collectively, the “Global Notes”). Accordingly,
unless and until it is exchanged for individual certificates, this Note may not be transferred except as a whole (i) by The Depository
Trust Company (the “Depositary”) to a nominee of the Depositary, (ii) by a nominee of the Depositary to the
Depositary or another nominee of the Depositary, or (iii) by the Depositary or a nominee of the Depositary to a successor depositary
or any nominee of such successor. Ownership of beneficial interests in this Security will be shown on, and the transfer of that
ownership will be effected only through, records maintained by the applicable Depositary or its nominee (with respect to interests
of persons that have accounts with the Depositary (“Participants”)) and the records of Participants (with respect
to interests of persons other than Participants). Beneficial interests in Notes owned by persons that hold through Participants
will be evidenced only by, and transfers of such beneficial interests with such Participants will be effected only through, records
maintained by such Participants. Except as provided below, owners of beneficial interests in this Note will not be entitled to
have any individual certificates and will not be considered the owners or Holders thereof under the Indenture.

 

Except in the limited
circumstances set forth in the Base Indenture, Participants and owners of beneficial interests in the Global Notes will not be
entitled to receive Notes in the form of individual certificates and will not be considered Holders. None of the Company, the
Trustee, the Security Registrar, the Paying Agent or any of their respective agents will be liable for any delay by the Depositary,
its nominee or any direct or indirect Participant in identifying the beneficial owners of the related Notes. The Company, the
Trustee, the Security Registrar, the Paying Agent and each of their respective agents may conclusively rely on, and will be protected
in relying on, instructions from the Depositary or its nominee for all purposes, including with respect to the registration and
delivery, and the respective principal amounts, of the Notes to be issued.

 

Except as provided
in Section 305 of the Base Indenture and Section 3.02(f) of the Supplemental Indenture, beneficial owners of Global Notes will
not be entitled to receive physical delivery of Notes in the form of individual certificates, and no Global Note will be exchangeable
except for another Global Note of like denomination and tenor to be registered in the name of the Depositary or its nominee. Accordingly,
each person owning a beneficial interest in a Global Note must rely on the procedures of the Depositary and, if such person is
not a Participant, on the procedures of the Participant through which such person owns its interest, to exercise any rights of
a Holder under the Notes.

 

    	 	A-6	 

     

    

 

The laws of some
jurisdictions may require that certain purchasers of securities take physical delivery of those securities in definitive form.
Accordingly, the ability to transfer interests in the Notes represented by a Global Note to those persons may be limited. In addition,
because the Depositary can act only on behalf of its Participants, who in turn act on behalf of persons who hold interests through
Participants, the ability of a person having an interest in Notes represented by a Global Note to pledge or transfer such interest
to persons or entities that do not participate in the Depositary’s system, or otherwise to take actions in respect of such
interest, may be affected by the lack of an individual certificate in respect of such interest. None of the Company, the Trustee,
the Paying Agent and the Security Registrar will have any responsibility or liability for any aspect of the records relating to
or payments made on account of Notes by the Depositary, or for maintaining, supervising or reviewing any records of the Depositary
relating to the Notes.

 

The Trustee will
act as the Company’s Paying Agent with respect to the Notes through its Corporate Trust Office presently located at 950 17th
St., 5th Floor, Denver, CO 80202. The Company may at any time rescind the designation of a Paying Agent, appoint a successor
Paying Agent, or approve a change in the office through which any Paying Agent acts.

 

Notices to the Holders
of individual certificates will be given to such Holders at their respective addresses in the Register, or in the case of Global
Notes, electronic delivery in accordance with DTC’s applicable procedures.

 

The Indenture contains
provisions setting forth certain conditions to the institution of proceedings by the Holders of Notes with respect to the Indenture
or for any remedy under the Indenture.

 

This Note shall be
governed by and construed in accordance with the law of the state of New York without reference to its principles of conflict of
laws (other than Section 5-1401 of the General Obligations Law).
