 FIRST SUPPLEMENTAL INDENTURE 

THIS FIRST SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of June 24, 2020, is between Horizon
Bancorp, Inc., an Indiana corporation (the “Company”), and Wilmington Trust, 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 

WHEREAS, the Company and the Trustee have executed and delivered a Indenture for Subordinated Debt, dated as of the date hereof (the
“Base Indenture” and, as supplemented, including by this Supplemental Indenture, and further supplemented from time to time, 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; 
 WHEREAS, the Company desires
to initially issue and sell $60,000,000 aggregate principal amount of a new series of Securities of the Company designated as its 5.625% Fixed-to-Floating Rate
Subordinated Notes due 2030 (the “Notes”) as of the date hereof and such issuance and sale have been authorized by resolutions adopted by the Board of Directors of the Company and the Authorized Committee of the Board of Directors
of the Company; 
 WHEREAS, the Company desires to establish the terms of the Notes; 

WHEREAS, the Company acknowledges that all things necessary to make this Supplemental Indenture a legal, binding and enforceable

Indenture have been done; 
 WHEREAS, the Company has complied with all conditions precedent provided for in the Base Indenture
relating to this Supplemental Indenture; and 
 WHEREAS, the Company has requested that the Trustee execute and deliver this
Supplemental Indenture. 
 NOW, THEREFORE, THE PARTIES TO THIS SUPPLEMENTAL INDENTURE WITNESSETH: 

For and in consideration of the premises stated herein and the purchase of the Notes by the Holders thereof, the Company and the Trustee
covenant and agree, for the equal and proportionate benefit of the Holders of the Notes, as follows: 

  
 1 













 ARTICLE I 

SCOPE OF SUPPLEMENTAL INDENTURE 

Section 1.01.    Scope. 

This Supplemental Indenture constitutes a supplement to the Base Indenture and an integral part of the Indenture and shall be read together
with the Base Indenture as though all the provisions thereof are contained in one instrument. Except as expressly amended by the 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: 
 (a)    all
terms used in this Supplemental Indenture which are not otherwise defined herein shall have the meanings they are given in the Base Indenture and include the plural as well as the singular; 

(b)    the provisions of general application stated in the Base Indenture shall apply to this Supplemental Indenture,
except that the words “herein,” “hereof,” “hereto” and “hereunder” and other words of similar import refer to this Supplemental Indenture as a whole and not to the Base Indenture or any particular Article,
Section or other subdivision of the Base Indenture or this Supplemental Indenture; and 
 (c)    Section 1.01 of the
Base Indenture is amended and supplemented, solely with respect to the Notes, by inserting the following additional defined terms in their appropriate alphabetical positions or replacing such terms in the Base Indenture: 

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

“Bankruptcy Law” means Title 11, U.S. Code, or any similar federal or state law for the relief of debtors or the protection
of creditors. 
 “Benchmark” means, initially, Three-Month Term SOFR; provided that if the Calculation Agent determines on
or prior to the Reference Time 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. 
 “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 

  
 2 













 
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: 

(i)    Compounded SOFR; 

(ii)    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; 

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

 (iv)    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: 

(i)    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; 

(ii)    if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, then
the ISDA Fallback Adjustment; and 
 (iii)    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 decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Calculation Agent decides 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). 

  
 3 













 “Benchmark Replacement Date” means the earliest to occur of the following
events with respect to the then-current Benchmark: 
 (i)    in the case of clause (1) of the
definition of “Benchmark Transition Event,” the relevant Reference Time in respect of any determination; 

(ii)    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 

(iii)    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, for purposes of the
definitions of Benchmark Replacement Date and Benchmark Transition Event, references to the Benchmark also include any reference rate underlying the Benchmark (for example, if the Benchmark becomes Compounded SOFR, references to the Benchmark would
included SOFR). 
 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: 
 (i)    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; 

(ii)    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; 
 (iii)    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 













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

close. 
 “Calculation Agent” means the agent appointed by the Company prior to the commencement of the Floating Rate
Period (which may include the Company or any of its Affiliates) to act in accordance with Section 3.02(e)(iv).

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: 

(i)    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: 
 (ii)    if, and to the
extent that, the Calculation Agent determines that Compounded SOFR cannot be determined in accordance with clause (i) 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. 

For the avoidance of doubt, the calculation of Compounded SOFR shall exclude the Benchmark Replacement Adjustment (if applicable) and the
spread of 549 basis points per annum.

(including overnight) having approximately the same length (disregarding business day adjustment) as the applicable tenor for the then-current Benchmark.

the Company; (y) any trade account 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 a successor administrator), on the Federal Reserve Bank of New York’s Website. 
 “Tax Event” means

the United States or any of its political subdivisions or taxing authorities; (b) 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 (c) 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 original issue date of the Notes, 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. 

  
 8 













 “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.

“Three-Month Term SOFR” means the rate for 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, without limitation, 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 decides 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 decides 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 (a) 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 original issue date of the Notes, (b) any proposed change in those laws, rules or regulations that is announced or becomes effective after the original issue
date of the Notes, or (c) 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 original issue date of the Notes, 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 Board of Governors of the Federal Reserve System (the “Federal Reserve”) (or, as and if applicable, the capital adequacy rules or regulations of any successor appropriate federal banking
agency) 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.

required to comply with any law or with any rules of any securities exchange or usage. The Notes shall be dated the date of their authentication. The signature of any of these officers on the Notes may be manual, facsimile or electronic. Signatures
by facsimile or electronic transmission shall be of the same legal effect, validity or enforceability as a manually executed signature in ink or the use of a paper-based recordkeeping system, as applicable, to the fullest extent and as provided for
in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, and any other similar state laws based on the Uniform Electronic Transactions Act. 

(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 of the Notes. The following terms relating to the Notes are hereby established: 

(a)    Title. The Notes shall constitute a series of Securities having the title “5.625% Fixed-to-Floating Rate Subordinated Notes due 2030” and the CUSIP number 440407 AA2. 

(b)    Principal Amount. The aggregate principal amount of the Notes that may be authenticated and delivered under
the Indenture, as amended hereby, shall initially be $60,000,000 on the Issue Date. Provided that 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 of the Notes, 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 or except for 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 the DTC. Any Additional Notes and the Notes shall constitute a single series under the Indenture and
have the same terms as to status, redemption or otherwise as the Notes. All references to the Notes shall include any Additional Notes, unless the context otherwise requires. 

(c)    Person to Whom Interest Is Payable. Any interest which is payable, but not so punctually paid or duly
provided for on any Interest Payment Date, shall cease to be payable to the Holder on the relevant record date by virtue of having been a Holder on such date, and such 

  
 10 













 
defaulted interest may be paid by the Company to the person in whose name the Notes are registered at the close of business on a special record date for the payment of such defaulted interest to
be fixed by the Company, notice whereof shall be given to Holders of Notes of this series not less than 10 days prior to such special record date that complies with Section 2.05(b) of the Base Indenture, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed and upon such notice as may be required by such exchange and in compliance with the Base Indenture. However, interest that is paid on
the Maturity Date will be paid to the person to whom the principal will be payable. 
 (d)    Maturity Date. The
entire outstanding Principal of the Notes shall be payable on July 1, 2030 (the “Maturity Date”). 

(e)    Interest. 

(i)    The Notes will bear interest at a fixed rate of 5.625% per annum from and including June 24,
2020 to, but excluding, July 1, 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 January 1 and July 1 of
each year, commencing on January 1, 2021 (each such date a “Fixed Rate Interest Payment Date”). The last Fixed Rate Interest Payment Date shall be July 1, 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 (each
such date, a “Fixed Rate Regular Record Date”). 
 (ii)    The Notes will bear a
floating interest rate from, and including July 1, 2025, to, but excluding, the Maturity Date or earlier Redemption Date (the “Floating Rate Period”). The floating interest rate will be reset quarterly, and the interest rate
for any Floating Rate Period shall be equal to the then-current Three-Month Term SOFR plus 549 basis points for each quarterly interest period during the Floating Rate Period. During the Floating Rate Period, interest on the Notes will be payable
quarterly in arrears on January 1, April 1, July 1, and October 1 of each year commencing, on October 1, 2025 (each such date, a “Floating Rate Interest Payment Date”, and together with a Fixed Rate Interest
Payment Date, an “Interest Payment Date”). 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 (each such date, a “Floating Rate Regular Record Date”). Notwithstanding the foregoing, if Three-Month Term SOFR (or other applicable Benchmark) is less
than zero, then Three-Month Term SOFR (or other such Benchmark) shall be deemed to be zero. The Calculation Agent will provide the Company and the Trustee with the interest rate in effect on the Notes promptly after the Reference Time (or such 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 to, but excluding,
July 1, 2025, and, the amount of interest payable on any Floating Rate Interest Payment Date during the Floating Rate Period will be computed on 

  
 11 













 
the basis of a 360-day year on the basis of the actual number of days elapsed. The Company or the Calculation Agent, as applicable, shall calculate the
amount of interest payable on any Interest Payment Date and the Trustee shall have no duty to confirm or verify any such calculation. 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 of interest payable on such Interest Payment Date or of principal and interest payable on the Maturity Date will be paid on the next succeeding day which is a Business Day (any payment made on such date will be treated
as being made on the date that the payment was first due and no interest on such payment will accrue for the period from and after such scheduled Interest Payment Date); provided, that in the event that 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. 
 (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’s determination
of any interest rate and its calculation of interest payments for any period will be maintained on file at the Calculation Agent’s principal offices, will be made available to any Holder of the Notes upon request and will be provided to the
Trustee. 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. 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. The Trustee shall not be under any duty to succeed to, assume, or otherwise perform, any duties of the
Calculation Agent, or to appoint a successor or replacement in the event of the Calculation Agent’s resignation or removal or to replace the Calculation Agent in the event of a default, breach or failure of performance on the part of the
Calculation Agent with respect to the Calculation Agent’s duties and obligations hereunder. 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. 

  
 12 













 (v)    Effect of Benchmark Transition Event. 

(A)    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 determination of the Benchmark on any date, then the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Notes during the
Floating Rate Period in respect of such determination on such date and all determinations on all subsequent dates. In connection with the implementation of a Benchmark Replacement, the Company or the Calculation Agent will have the right to make
Benchmark Replacement Conforming Changes from time to time. 
 (B)    Notwithstanding anything set forth
in Section 3.02(e)(ii) above, if the Calculation Agent determines on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three- Month Term SOFR, then
the provisions set forth in this Section 3.02(e)(v) will thereafter apply to all determinations of the interest 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 549 basis points. 

(C)    The Company and the Calculation Agent are expressly authorized to make certain 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 Section 3.02(e)(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 of the Notes 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 of the Notes 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 (i) upon the
occurrence of the Benchmark Transition Event or the Benchmark Replacement Date, and (ii) of any Benchmark Replacements, Benchmark Replacement Conforming Changes and other items affecting the interest rate on the Notes after a Benchmark
Transition Event. 

  
 13 













 (vii)    The Trustee (including in its capacity as
paying agent) shall have no (i) responsibility or liability for the (A) Three-Month Term SOFR Conventions, (B) selection of an alternative reference rate to Three-Month Term SOFR (including, without limitation, 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, and (ii) liability for any failure or delay in performing its duties hereunder as a result of the unavailability of a Benchmark rate as described in the definition thereof, including, without
limitation, 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, without limitation, in regards to Three-Month Term SOFR Conventions, a Benchmark Transition Event,
Benchmark Replacement Date, and Benchmark Replacement Conforming Changes. The Trustee shall not be responsible or liable for the actions or omissions of the Calculation Agent, or any failure or delay in the performance of the Calculation
Agent’s duties or obligations, nor shall it be under any obligation to monitor or oversee the performance of the Calculation Agent. The Trustee shall be entitled to conclusively rely on any determination made, and any instruction, notice,
Officers’ Certificate or other instruction or information provided by the Calculation Agent without independent verification, investigation or inquiry of any kind. The Trustee shall not be obligated to enter into any amendment or supplement
hereto that adversely impacts its rights, duties, obligations, immunities or liabilities (including, without limitation, in connection with the adoption of any Benchmark Replacement Conforming Changes). 

(viii)    If the then-current Benchmark is Three-Month Term SOFR, the Calculation Agent will have the right
to establish the Three-Month Term SOFR Conventions and if 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 shall be issued in global form, 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 in global
form, 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 person specified for payment in accordance with Section 3.02(e)(i) and (e)(ii)
above. A global security with respect to the Notes shall be exchangeable for physical securities of such series only if: (i) DTC is at any time unwilling or unable or ineligible to continue as a depository or ceases to be a clearing agency
registered under the Exchange Act and a successor depository is not appointed by the Company within 90 days of the date the Company is so notified in writing, or (ii) the Company executes and delivers to the Trustee a Company Order to the
effect that such global securities shall be so exchangeable (and the Trustee consents thereto). 

  
 14 













 (g)    Redemption. The Notes shall be redeemable, in each case,
in whole or in part from time to time, at the option of the Company beginning with the Interest Payment Date on July 1, 2025, but not prior thereto (except upon the occurrence of certain events specified below), and on any Interest Payment Date
thereafter (each, a “Redemption Date”), 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. The Notes may not otherwise be redeemed
prior to the Maturity Date, except that the Company may, at its option, redeem the Notes 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-l et seq.). Any such redemption will be at a Redemption Price equal to 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 3 of the Base Indenture shall apply to any redemption of the Notes pursuant to this Section 3.02(g). Any partial redemption will be made in accordance with DTC’s applicable procedures among
all of the Holders of the Notes. If any Note is to be redeemed in part only, the notice of redemption relating to such Note shall state that it is a partial redemption and the portion of the principal amount thereof to be redeemed, and 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. The Notes are not subject to redemption or prepayment at the option of the Holders. 

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 payment of principal and interest of the Notes
shall be payable in, the currency of the United States of America. 
 (l)    Registered Form. The Notes shall be
issuable as global Registered 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. Section 2.11 of the Base
Indenture shall apply to the Notes. 

  
 15 













 (m)    Events of Default. The Events of Default provided for in
Section 6.01 of the Base Indenture shall apply to the Notes, provided that the following shall be added as a new subsection (g) after subsection (f): 

“(g) in the event of an appointment of a Custodian for the Company’s Material Subsidiary.” 

and 
 The last paragraph of
Section 6.01 of the Base Indenture shall be substituted with the following: 
 “If an Event of Default under clause (d), (e) or
(g) of Section 6.01 occurs and is continuing, then the principal amount of all the Notes, together with premium, if any, and 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.” 

(n)    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. 
 (o)    Satisfaction and Discharge;
Defeasance. Articles 12 and 14 of the Base Indenture shall apply to the Notes. 
 (p)    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 (as a result of a change in law or otherwise), the Company will not pay additional amounts with respect to
such tax or assessment. 
 (q)    Notices to Holders. Any notices required to be given to Holders of the Notes
shall be given to 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 or repurchase) to a
holder of a Note (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. 
 (r)    Additional Terms. Other terms applicable to the Notes are as otherwise provided for
in the Base Indenture, as supplemented by this Supplemental Indenture. 

  
 16 













 ARTICLE IV 

ADDITIONAL PROVISIONS 

Section 4.01.    Additional Provisions. 

(a)    Section 10.01 of the Base Indenture shall apply to the Notes, provided that, with respect to the Notes, the
following text shall be deemed to be inserted as a new subsection (i) after subsection (h): 
 “(i) Not in limitation of the
foregoing, without the consent of any Holder of Securities, the Company and the Trustee may amend or supplement the Indenture or the Notes (i) to conform the terms of the Indenture and the Notes to the “Description of the
Notes” section in the prospectus supplement, dated June 17, 2020, relating to the offering of the Notes; or (ii) 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 shall have no obligation to review any such conventions or transition provisions determined by the Calculation Agent and included in
any such amendment and shall be entitled to conclusively rely on a Company Request (in addition to any other orders, certificates and opinion) as to whether any such event in clause (ii) has occurred.” 

ARTICLE V 
 SUBORDINATION
OF SECURITIES 
 Section 5.01.    Agreement of Subordination. The Company covenants and agrees, and each
Holder of Notes issued hereunder by accepting a Note likewise covenants and agrees, that all Notes shall be issued subject to the provisions of this Article V; 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 and interest on all
Notes (including, but not limited to, the redemption price with respect to the Notes called for redemption in accordance with Section 3.02(g)) issued hereunder 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 V shall prevent the occurrence of any Default or Event of Default hereunder. 

Section 5.02.    Payments to Holders. No payment shall be made with respect to the principal of or interest on
the Notes (including, but not limited to, the redemption price with respect to the Notes to be 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, if: 
 (a)    a default in the payment of principal, premium, interest or other
obligations due on any Senior Indebtedness occurs and is continuing (or, in the case of Senior Indebtedness for which there is a period of grace, in the event of such a default that continues beyond the period of grace, if any, 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 a Responsible Officer of the Trustee receives a notice of such default from a Representative or
the Company; or 

  
 17 













 (b)    a default, other than a payment default, on a Designated Senior
Indebtedness occurs and is continuing that then permits holders of such Designated Senior Indebtedness to accelerate its maturity and a Responsible Officer of the Trustee receives a notice of the default (a “Payment Blockage
Notice”) from a Representative or the Company. 
 If the Trustee receives any Payment Blockage Notice pursuant to clause
(b) above, 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, premium, if any, and interest on the Notes that have come due have been paid in full in cash. No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage
Notice to the Trustee 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: 
 (ii)    the date upon which the
default is cured or waived or ceases to exist, or 
 (iii)    in the case of a default referred to in
clause (b) above, 179 days pass after notice is received if the maturity of such Designated Senior Indebtedness has not been accelerated, unless this Article V otherwise prohibits the payment or distribution at the time of such payment or
distribution. 
 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 6 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 of the Notes or the Trustee would be entitled, except for the provision of this Article V, 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 of the Notes 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 their representative or representatives, or to the trustee or trustees under any indenture pursuant
to which any instruments evidencing any Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay all Senior Indebtedness in full, in cash 

  
 18 













 
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 of the Notes 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. 
 (iv)    For purposes of this Article V, 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 V 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 this Article V shall not be deemed a dissolution, winding-up, liquidation or reorganization for the
purposes of this Section 5.02 if such other person shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions stated in this Article V. 

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 of Notes 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 Security Registrar or paying agent (or successor agent) to the Trustee as being the address to which the Trustee should send its notice pursuant to this Section 5.02, 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, without limitation, by way of setoff or otherwise), prohibited by the foregoing, shall be received by the Trustee or the Holders of the Notes 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 or 

  
 19 













 
representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing any Senior Indebtedness may have been issued, 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. 

(v)    Nothing in this Article V shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 7.06 of the Base Indenture. This Section 5.02 shall be subject to the further provisions of Section 5.05. For the sake of clarity, 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 of the Notes 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 V (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 of the Notes or the Trustee would be entitled except for the provisions of this Article V, and no payment over pursuant to the
provisions of this Article V, to or for the benefit of the holders of Senior Indebtedness by Holders of the Notes or the Trustee, shall, as between the Company, its creditors other than holders of Senior Indebtedness, and the Holders of the Notes,
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 of the Notes pursuant to the subrogation provisions of this
Article V, 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 V are and are intended
solely for the purposes of defining the relative rights of the Holders of the Notes, on the one hand, and the holders of the Senior Indebtedness, on the other hand. 

Nothing contained in this Article V 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 of the Notes, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Notes the principal of (and premium, if any) 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 of the Notes 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 V of the
holders of Senior Indebtedness in respect of cash, property or notes of the Company received upon the exercise of any such remedy. 

  
 20 













 Upon any payment or distribution of assets of the Company referred to in this Article V, the
Trustee, subject to the provisions of Section 7.01 of the Base Indenture, and the Holders of the Notes 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 of the Notes, 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 V. 

Section 5.04.    Authorization to Effect Subordination. Each Holder of a Note by the holder’s 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 V 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 6.03 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 of the Notes. 
 Section 5.05.    Notice to Trustee. The Company shall give prompt
written notice in the form of an Officers’ Certificate 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 in respect of the Notes pursuant to the provisions of this Article V. Notwithstanding the provisions of this Article V 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 V, unless and until a Responsible Officer of the Trustee shall have received written notice thereof at the
Corporate Trust Office from the Company (in the form of an Officers’ Certificate) or a Representative or a holder or holders of Senior Indebtedness or from any trustee thereof; and before the receipt of any such written notice, the Trustee,
subject to the provisions of Section 6.01 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, without limitation, the payment of the principal of, or premium, if any, or interest on any Note) the Trustee shall not have received, with respect to such monies, the notice provided
for in this Section 5.05, 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 V to the contrary, nothing shall prevent any payment by the Trustee to the Holders of monies deposited with it pursuant to Section 12.01 of the Base Indenture, and any such payment shall not be subject to the provisions of
Section 5.01 or 5.02. 

  
 21 













 The Trustee, subject to the provisions of Section 7.01 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 V, 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 V, 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. 

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 V 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 7.13 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 V shall apply to the Company’s obligations to the Trustee under Section 7.06 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 V, 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 7.01 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 of Notes, the
Company or any other person money or assets to which any holder of Senior Indebtedness shall be entitled by virtue of this Article V 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, without limitation, Designated Senior Indebtedness) shall have the right to rely upon this Article V, 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.

 THIS SECURITY IS ISSUABLE IN DENOMINATIONS OF $1,000 AND INTEGRAL MULTIPLES OF $1,000 IN EXCESS THEREOF. AS
PROVIDED IN THE INDENTURE AND SUBJECT TO CERTAIN LIMITATIONS THEREIN, SECURITIES OF THIS SERIES ARE EXCHANGEABLE FOR A LIKE AGGREGATE PRINCIPAL AMOUNT OF SECURITIES OF SUCH SERIES OF A DIFFERENT AUTHORIZED DENOMINATION, AS REQUESTED BY THE HOLDER
SURRENDERING THE SAME. 
 Horizon Bancorp, Inc., an Indiana corporation (hereinafter called the “Company,” which term
includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or its registered assigns, the principal sum of $60,000,000 on July 1, 2030 (such date is
hereinafter referred to as the “Stated Maturity Date”), unless redeemed prior to such date, and to pay interest thereon (i) from, and including, June 24, 2020, to, but excluding, July 1, 2025 or earlier redemption
date (the “Fixed Rate Period”), at a rate of 5.625% per annum, semi-annually in arrears on January 1 and July 1 of each year, commencing January 1, 2021 (each such date, a “Fixed Rate Interest Payment
Date”) and (ii) from, and including, July 1, 2025 to, but excluding, the Stated Maturity Date or earlier redemption date (the “Floating Rate Period”), at a rate equal to Three-Month Term SOFR, reset quarterly,

the Floating Rate Period will be computed on the basis of a 360-day year and the number of days actually elapsed. In the event that any scheduled Interest Payment Date for this Note falls on a day that is not
a Business Day, then payment of interest payable on such Interest Payment Date will be paid on the next succeeding day which is a Business Day (any payment made on such date will be treated as being made on the date that the payment was first due
and no interest on such payment will accrue for the period from and after such scheduled Interest Payment Date); provided, that in the event that 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. 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 at the office or agency of the

 REVERSE OF GLOBAL NOTE 

5.625% 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 “5.625% Fixed-to-Floating Rate Subordinated Notes due 2030” (herein called the “Notes”) initially issued in an aggregate principal amount of $60,000,000 on
June 24, 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 Indenture for Subordinated Debt,
dated as of June 24, 2020 (the “Base Indenture”), between the Company and Wilmington Trust, National Association, as Trustee (herein called the “Trustee,” which term includes any successor trustee), as
supplemented and amended by the First Supplemental Indenture between the Company and the Trustee, dated as of June 24, 2020 (the “Supplemental Indenture,” and the Base Indenture as supplemented and amended by the Supplemental
Indenture, the “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 terms, conditions and provisions of this
Note modify, supplement or are inconsistent with those of the Indenture, then the terms, conditions and other provisions of this Note shall govern to the extent that such terms, conditions and other provisions of this Note are not inconsistent with
the terms, conditions and 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. To the extent that any capitalized term used in this Note and defined herein is also defined in the Indenture but conflicts
with the definition provided in the Indenture, the definition of the capitalized term in this Note shall control. 
 The indebtedness of the
Company evidenced by the Notes, including the principal thereof, premium, if any, and interest thereon, is, to the extent and in the manner set forth in the Indenture, 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, and on the terms and subject to the terms and conditions set forth in the Indenture, and shall rank pari passu in right of payment with all other Securities and with
all other unsecured subordinated indebtedness of the Company and 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 his 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 

  
 A-5 













 
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 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 6 of the Base Indenture and Section 3.02(m) of the Supplemental Indenture. Accordingly, the Holder of this Note has no right to accelerate the maturity of this Note in the event that the
Company fails to pay principal or 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 July 1, 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, 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 2 of the Base Indenture and Section 3.02(g) of
the Supplemental Indenture shall apply to the redemption of any Notes by the Company. 
 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 of the Notes 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 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 Register
described in Section 2.07 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 by, or


  
 A-6 













 
accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new 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 any 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, this Note may not be transferred except as a whole by The Depository Trust Company (the
“Depositary”) to a nominee of such Depositary or by a nominee of such Depositary or by the Depositary or any nominee 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 interest 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 in the Indenture, 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. As a result, the rights of owners of beneficial interests in such Global Notes shall be exercised only through the Depositary. 

Any “depository institution,” as defined in Section 3(c)(1) of the Federal Deposit Insurance Act, which holds a Note (or
beneficial interest therein) shall be deemed to have agreed by acquiring such Note (or beneficial interest therein) to waive any rights to offset all or any portion of the indebtedness represented by such Note (or beneficial interest therein)
against any indebtedness or other obligations of such institution to the Company. 
 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, and none of them will have any
responsibility or liability for any aspect of the records relating to, or payments made on account of, the Notes by the Depositary, or for maintaining, supervising or reviewing any records of the Depositary relating to the 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. 

  
 A-7 













 If certain Events of Default with respect to the Notes shall occur and be continuing, the
principal of the Notes will automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. The Company waives demand, presentment for prepayment, notice of nonpayment, notice
of protest and all other notices to the extent it may lawfully do so. 
 The Trustee will act as the Company’s paying agent with
respect to the Notes through its Corporate Trust Office presently located at Rodney Square North, 1100 North Market Street, Wilmington, Delaware 19890, Attention: Horizon Bancorp, Inc. Administrator. 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. 

Nothing in this Note, express or implied, shall give to any person, other than the Holder of this Note, the parties hereto and their permitted
successors hereunder, any benefit of any legal or equitable right, remedy or claim hereunder. 
 All notices under this Note shall be in
writing and in the case of the Company, addressed to the Company at 515 Franklin Street, Michigan City, Indiana, 46360, Attention: Chief Financial Officer, or, in the case of the Trustee the Corporate Trust Office, or to such other address of the
Trustee as the Trustee may notify the holder of this Note. All notices to the Holder of this Note will be given to the Holder at its address as it appears in the Security Register. 

All covenants and agreements by the Company in this Note and the Indenture shall bind the Company’s successors and assigns, including
successors by operation of law resulting from a merger or consolidation of the Company, or successors resulting from the transfer of the Company’s assets and liabilities substantially or entirely, to another entity
(“Successors”). Any Successor shall expressly assume in writing all the Company’s obligations hereunder prior to becoming a Successor, and upon becoming a Successor, shall perform all the Company’s obligations hereunder
and make all payments due hereunder. 
 In case any provision in this Note 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. 
 EACH OF THE COMPANY, THE
TRUSTEE AND EACH HOLDER OF THIS NOTE BY ITS ACCEPTANCE HEREOF, HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT IT MAY HAVE TO TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF
OR RELATING TO THIS NOTE, THE INDENTURE, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. 
 This Note shall be governed by and construed
in accordance with the laws of the State of New York and, where applicable, the federal laws of the United States of America.
