ARTICLE I


DEFINITIONS AND OTHER PROVISIONS OF GENERAL APPLICATION


 


Section 1.01Definitions. Capitalized terms
used herein and not otherwise defined herein have the meanings assigned to them in the Base Indenture. The words “herein”,
“hereof” and “hereby” and other words of similar import used in this Fourth Supplemental Indenture refer to this
Fourth Supplemental Indenture as a whole and not to any particular section hereof.


 


As used herein, the following terms have the specified
meanings:


 


“Additional Notes” has the meaning
set forth in Section 2.08 of this Fourth Supplemental Indenture.


 


“Base Indenture” has the meaning
specified in the recitals of this Fourth Supplemental Indenture.


 






    	 	2	 



     


    

 


“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) if 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) or the then-current Benchmark, 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; or
	 	 	 	 
	 	(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 notes 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 “floating rate period,” timing and frequency of determining rates with respect to each Floating Rate 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:


 


	 	(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, 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 include 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:


 


	 	(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.


 


“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 2.10. The Company shall initially act as the Calculation Agent.


 






    	 	4	 



     


    

 


“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 notes at such time.


 


For the avoidance of doubt, the calculation of Compounded
SOFR will exclude the Benchmark Replacement Adjustment (if applicable) and the spread of 235 basis points per annum.

provisions of the Base Indenture, and thereafter “Company” shall mean such successor corporation.

Section 2.05.


 


Further to the above, pursuant to Section 2.2.8 of

Notes shall be issued as part of the existing series of Notes issued pursuant to this Fourth Supplemental Indenture and shall have terms
identical in all material respects (except for the issue date, issue price, initial interest accrual date and the first interest payment
date) to any Outstanding Notes and shall be treated together with any Outstanding Notes as a single series of Notes for all purposes under
the Indenture. Any Additional Notes issued hereunder shall rank equally and ratably with the Notes originally issued pursuant to this
Fourth Supplemental Indenture, shall have the same CUSIP number and shall trade interchangeably with such Notes and shall otherwise constitute
Notes for all other purposes hereof. Any Additional Notes may be issued pursuant to authorization provided by one or more Board Resolutions.
No Additional Notes shall be issued at any time that there is an Event of Default under the Indenture with respect to the Notes that has

	 	(a)	 	The Notes will bear interest at a fixed rate of 2.875% per annum from and including August 6, 2021 to, but excluding, August 15, 2026 (the “Fixed Rate Period”). Interest accrued on the Notes during the Fixed Rate Period will be payable semi-annually in arrears on February 15 and August 15 of each year, commencing on February 15, 2022 (each such date, a “Fixed Rate Interest Payment Date”). The last Fixed Rate Interest Payment Date shall be August 15, 2026. 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”). 
	 	 	 	 
	 	(b)	 	The Notes will bear a floating interest rate from, and including August 15, 2026, 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 Benchmark plus 235 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 February 15, May 15, August 15 and November 15 of each year commencing on November 15, 2026 (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).
	 	 	 	 
	 	(c)	 	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, August 15, 2026, 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 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.
	 	 	 	 
	 	(d)	 	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 the Benchmark in respect of each Floating Rate Period. The calculation of the Benchmark 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.

	 	(e)	 	Effect of Benchmark Transition Event.
	 	 	 	 
	 	 	 	(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 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 Calculation Agent will have the right to make Benchmark Replacement Conforming Changes from time to time.
	 	 	 	 	 	 
	 	 	 	(2)	 	Notwithstanding anything set forth in Section 2.10(b) 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 the then-current Benchmark, then the provisions set forth in this Section 2.10(e) will thereafter apply to all determinations of the interest rate 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 235 basis points.
	 	 	 	 	 	 
	 	 	 	(3)	 	The Calculation Agent is expressly authorized to make certain determinations, decisions and elections under the terms of the Notes, including with respect to the use of Three-Month Term SOFR as the Benchmark and under this Section 2.10(e). Any determination, decision or election that may be made 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 as Calculation Agent, will be made in the Company’s sole discretion, (C) if made by a Calculation Agent other than the Company, 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 Indenture, shall become effective without consent from the Holders of the Notes, the Trustee or any other party. 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.
	 	 	 	 	 	 
	 	 	 	(4)	 	The Company (or its Calculation Agent) shall notify a Responsible Officer of the Trustee in writing (A) upon the occurrence of the Benchmark Transition Event or the Benchmark Replacement Date, and (B) of any Benchmark Replacements, Benchmark Replacement Conforming Changes and other items affecting the interest rate on the Notes after a Benchmark Transition Event.

	 	 	 	(5)	 	The Trustee (including in its capacity as Paying Agent) shall have no (A) responsibility or liability for the (1) Three-Month Term SOFR Conventions, (2) 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), (3) determination or calculation of a Benchmark Replacement, (4) determination of whether a Benchmark Transition Event or Benchmark Replacement Date has occurred, or (5) to determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable in connection with any of the foregoing, and in each such case under clauses (1) through (5) 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 (B) 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 Company or 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).
	 	 	 	 	 	 
	 	 	 	(6)	 	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.

Pursuant to Section 2.2.19 of the Base Indenture, so
long as any of the Notes are outstanding, the following provisions shall be applicable to the Notes in addition to the covenants contained
in Article IV of the Base Indenture:


 


Section 3.01Ownership of Material Subsidiary
Stock. Subject to the provisions of Article V of the Base Indenture, so long as any of the Notes are outstanding, the Company:


 


	 	(a)	 	will not, nor will it permit a Material Subsidiary to, directly or indirectly, sell, assign, pledge, transfer or otherwise dispose of any shares of, securities convertible into, or options, warrants or rights to subscribe for or purchase shares of, Voting Stock of a Material Subsidiary, nor will the Company permit a Material Subsidiary to issue any shares of, or securities convertible into, or options, warrants or rights to subscribe for or purchase shares of, Voting Stock of a Material Subsidiary if, in each case, after giving effect to any such transaction and to the issuance of the maximum number of shares of Voting Stock of such Material Subsidiary issuable upon the exercise of all such convertible securities, options, warrants or rights, the Company would cease to own, directly or indirectly, at least 80% of the issued and outstanding Voting Stock of such Material Subsidiary; and
	 	 	 	 
	 	(b)	 	will not permit a Material Subsidiary to:
	 	 	 	 
	 	 	 	(1)	 	merge or consolidate with or into any corporation or other Person, unless the Company is the surviving corporation or Person, or unless, upon consummation of the merger or consolidation, the Company will own, directly or indirectly, at least 80% of the surviving corporation’s issued and outstanding Voting Stock; or
	 	 	 	 	 	 
	 	 	 	(2)	 	lease, sell, assign or transfer all or substantially all of its properties and assets to any Person (other than the Company) in a single transaction or series of related transactions, unless, upon such sale, assignment or transfer, the Company will own, directly or indirectly, at least 80% of the issued and outstanding Voting Stock of that Person.


 


Notwithstanding the foregoing, any such sale, assignment,
pledge, transfer, disposition or issuance of securities, any such merger or consolidation or any such lease, sale, assignment or transfer
of properties and assets shall not be prohibited if: (A) required by law and such sale, assignment, pledge, transfer, disposition or issuance
of securities is made to any Person for the purpose of the qualification of such Person to serve as a director; (B) such sale, assignment,
pledge, transfer, disposition or issuance of securities is made by the Company or any of its Subsidiaries acting in a fiduciary capacity
for any Person other than the Company or any Subsidiary; (C) made in connection with the consolidation of the Company with or the sale,
lease or conveyance of all or substantially all of the assets of the Company to, or merger of the Company with or into any other Person
(as to which Article V of the Base Indenture shall apply); (D) required by any law or any rule, regulation or order of any governmental
agency or authority; or (E) required as a condition imposed by any law or any rule, regulation or order of any governmental agency or
authority to the acquisition by the Company, directly or indirectly, through purchase of stock or assets, merger, consolidation or otherwise,
of any Person; provided, that, in the case of (E) only, after giving effect to such disposition and acquisition, (y) at least 80% of the

pledge of any assets to secure borrowings incurred in the ordinary course of business, including, without limitation, deposit liabilities,
mortgage escrow funds, reverse repurchase agreements, Federal Home Loan Bank of Pittsburgh, recourse obligations incurred in connection

Section 3.02Liens. The Company will not,
nor will the Company permit a Material Subsidiary to, create, assume, incur or suffer to be created, assumed or incurred or to exist,
any pledge, encumbrance or lien, as security for indebtedness for borrowed money, upon any shares of Voting Stock of a Material Subsidiary
(or securities convertible into, or options, warrants or rights to subscribe for or purchase shares of that Voting Stock), directly or
indirectly, without making effective provision whereby the Notes shall be equally and ratably secured with any and all such indebtedness
if, treating such pledge, encumbrance or lien as a transfer of the shares of, or securities convertible into or options, warrants or rights
to subscribe for or purchase shares of, Voting Stock of such Material Subsidiary subject thereto to the secured party and after giving
effect to the issuance of the maximum number of shares of Voting Stock of such Material Subsidiary issuable upon the exercise of all such
convertible securities, options, warrants or rights, the Company would not continue to own at least 80% of the issued and outstanding
Voting Stock of such Material Subsidiary. Notwithstanding the foregoing, this Section shall not apply to any:


 


	 	(a)	 	pledge, encumbrance or lien upon any such shares of Voting Stock to secure indebtedness of the Company or a Subsidiary as part of the purchase price of such shares of Voting Stock, or incurred prior to, at the time of or within 120 days after acquisition thereof for the purpose of financing all or any part of the purchase price thereof;
	 	 	 	 
	 	(b)	 	lien for taxes, assessments or other government charges or levies (i) which are not yet due or payable without penalty, (ii) which the Company is contesting in good faith by appropriate proceedings so long as the Company has set aside on its books such reserves as shall be required in respect thereof in conformity with GAAP or (iii) which secure obligations of less than $1 million in amount;
	 	 	 	 
	 	(c)	 	lien of any judgment, if that judgment (i) is discharged, or stayed on appeal or otherwise, within 60 days, (ii) is currently being contested in good faith by appropriate proceedings so long as the Company has set aside on its books such reserves as shall be required in respect thereof in conformity with GAAP or (iii) involves claims of less than $1 million; or
	 	 	 	 
	 	(d)	 	any pledge or lien on the Voting Stock of a Material Subsidiary to secure a loan or other extension of credit by a Subsidiary subject to Section 23A of the Federal Reserve Act.


 


In case the Company or a Material Subsidiary shall
propose to create, assume, incur or suffer to be created, assumed or incurred or to exist, any pledge, encumbrance or lien, as security
for indebtedness for borrowed money, upon any shares of Voting Stock of a Material Subsidiary (or securities convertible into, or options,
warrants or rights to subscribe for or purchase shares of that Voting Stock), directly or indirectly, other than as permitted by subdivisions
(a) to (d), inclusive, of this Section, the Company will prior thereto give written notice thereof to the Trustee, and will prior to or
simultaneously with such pledge, encumbrance or lien, by supplemental indenture delivered to the Trustee, in form satisfactory to it,
effectively secure all the Notes equally and ratably with such indebtedness, by pledge, encumbrance or lien of such Voting Stock. Such
supplemental indenture shall contain the provisions, concerning the possession, control, release and substitution of encumbered and pledged
property and securities and other appropriate matters which are required or permitted by the TIA (as in effect at the date of execution
of such supplemental indenture) to be included in a secured indenture qualified under the TIA, and may also contain such additional and
mandatory provisions permitted by the TIA as the Company shall deem advisable or appropriate.

with Section 9.2 of the Base Indenture, the Company may omit in any particular instance to comply with any term, provision or condition
set forth in Sections 3.01 to 3.02 hereof, inclusive, with respect to the Notes if before the time for such compliance the Holders of
at least a majority in principal amount of the Outstanding Notes, by act of such Holders, either shall waive such compliance in such instance
or generally waived 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.

Section 5.01Events of Default. Pursuant
to Section 2.2.18 of the Base Indenture, Section 6.1 of the Base Indenture is hereby deleted and replaced in its entirety with the following:


 


Section 6.1Events of Default. Each of the following constitutes
an “Event of Default”:


 


	 	(a)	 	the Company defaults in the payment of any installment of interest on any of the Notes as and when the same shall become due and payable, and such default continues for a period of 30 days;
	 	 	 	 
	 	(b)	 	the Company defaults in the payment when due of all or any part of the principal of any of the Notes as and when the same shall become due and payable either at maturity, upon any redemption, upon acceleration of maturity or otherwise;
	 	 	 	 
	 	(c)	 	the Company fails to perform any other covenant or agreement on the part of the Company contained in the Notes or in this Indenture and such failure continues for a period of 90 days after the date on which notice specifying such failure, stating that such notice is a “Notice of Default” hereunder and demanding that the Company remedy the same, shall have been given, by registered or certified mail (or, if registered or certified mail is not then offered by the U.S. Post Office, by first class mail return receipt requested), to the Company by the Trustee, or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Notes at the time outstanding;
	 	 	 	 
	 	(d)	 	a court having jurisdiction in the premises shall enter (i) a decree or order for relief in respect of the Company or a Material Subsidiary in an involuntary case or proceeding under any applicable Bankruptcy Law now or hereafter in effect, (ii) or a decree or order adjudging the Company or a Material Subsidiary bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment, or composition of or in respect of the Company or a Material Subsidiary under any applicable federal or state law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator or other similar official of the Company or a Material Subsidiary or for any substantial part of its property or ordering the winding up or liquidation of its affairs, shall have been entered, and such decree or order shall remain unstayed and in effect for a period of 60 consecutive days;

    	 	15	 



     


    

 


	 	(f)	 	The Company or a Material Subsidiary defaults under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company or a Material Subsidiary having an aggregate principal amount outstanding of at least $25,000,000, or under any mortgage, indenture or instrument (including the Indenture) under which there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company or a Material Subsidiary having an aggregate principal amount outstanding of at least $25,000,000, whether such indebtedness now exists or is created in the future, which default (i) constitutes a failure to pay any portion of the principal of such indebtedness when due and payable after the expiration of any applicable grace period or (ii) results in such indebtedness becoming due or being declared due and payable prior to the date on which it otherwise would have become due and payable without, in the case of clause (i), such indebtedness having been discharged or, in the case of clause (ii), without such indebtedness having been discharged or such acceleration having been rescinded or annulled.


 







Upon becoming aware of any Event of Default, the Company

Section 5.02Acceleration. Pursuant to Section
2.2.18 of the Base Indenture, Section 6.2 of the Base Indenture is hereby deleted and replaced in its entirety with the following:


 


Section 6.2Acceleration. 


 


	 	(a)	 	(a)If any Event of Default specified in Sections 6.1(a), 6.1(b), 6.1(c) or 6.1(f) of the Base Indenture, as amended by this Fourth Supplemental Indenture, with respect to the Notes occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then Outstanding Notes may declare the principal amount (or, if any of the Notes are Discount Securities, such portion of the principal amount of such Notes as may be specified in the terms thereof) of all the Notes and interest accrued thereon to be due and payable immediately by a notice in writing to the Company (and to the Trustee if given by the Holders of the Outstanding Notes) and upon any such declaration, such principal amount (or such specified portion of the principal amount) shall become immediately due and payable.
	 	 	 	 
	 	(b)	 	If any Event of Default specified in Section 6.1(d) or 6.1(e) of the Base Indenture, as amended by this Fourth Supplemental Indenture, with respect to the Notes occurs, the principal amount (or, if any of the Notes are Discount Securities, such portion of the principal amount of such Notes as may be specified in the terms thereof) of all the Notes and interest accrued thereon shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable; provided, however, that if an Event of Default specified in Section 6.1(d) or 6.1(e) solely with respect to a Material Subsidiary occurs and is continuing, the principal amount of such Notes and interest accrued thereon shall not automatically become immediately due and payable, but may be accelerated by the Trustee or the Holders in accordance with the provisions of Section 6.2(a).
	 	 	 	 



 






    	 	16	 



     


    

 


	 	(c)	 	The Holders of a majority in aggregate principal amount of the Outstanding Notes with respect to which the Event of Default has occurred, by written notice to the Company and the Trustee, may on behalf of the Holders of all of the Notes rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree of a court of competent jurisdiction and if:
	 	 	 	 
	 	 	 	(1)	 	the Company has paid or deposited with the Trustee a sum sufficient to pay (A) all overdue interest on all Notes, (B) the principal of any Notes which have become due otherwise than by such acceleration and any interest thereon at the rate or rates prescribed therefor in the Notes, (C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in the Notes, and (D) all sums paid or advanced by the Trustee hereunder and the compensation and reasonable expenses, disbursements and advances of the Trustee, its agents and counsel; and
	 	 	 	 	 	 
	 	 	 	(2)	 	all existing Events of Default with respect to the Notes (other than the nonpayment of principal or interest that has become due solely because of the acceleration) have been cured or waived.
	 	 	 	 
	 	 	 	No such rescission shall affect any subsequent default or impair any right consequent thereon.
	 	 	 	 
	 	(d)	 	For all purposes under this Indenture, if a portion of the principal of any Discount Securities shall have been accelerated and declared due and payable pursuant to the provisions of this Indenture, then, from and after the date of such Event of Default, unless such Event of Default has been rescinded and annulled as provided above, the principal amount of such Discount Securities shall be deemed, for all purposes under this Indenture, to be such portion of the principal as shall be due and payable as a result of such acceleration, and the payment of such portion of the principal as shall be due and payable as a result of such acceleration, together with interest, if any, on such portion and all other amounts owing under such Discount Security, shall constitute payment in full of such Discount Securities.

Customers Bancorp, Inc.


2.875% Fixed-to-Floating Rate Senior Notes due 2031


 


Capitalized terms used herein shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated.


 


1.Payment of Principal and
Interest. Customers Bancorp, Inc. (the “Company”), a Pennsylvania corporation, promises to pay CEDE & CO.,
or registered assigns, the principal amount of ONE HUNDRED MILLION DOLLARS ($100,000,000) on August 15, 2031 (the “Maturity Date”),
unless redeemed prior to such date. This Note will bear interest at a fixed rate of 2.875 % per annum from and including August 6, 2021,
to, but excluding, August 15, 2026 (the “Fixed Rate Period”), unless redeemed prior to such date. Interest accrued
on this Note during the Fixed Rate Period will be payable semi-annually in arrears on February 15 and August 15 of each year (each such
date, a “Fixed Rate Interest Payment Date”), with the first such Fixed Rate Interest Payment Date being February 15,
2022, and the last such Fixed Rate Interest Payment Date being August 15, 2026, unless redeemed prior to such date. This Note will bear
interest at a floating per annum interest rate from and including August 15, 2026, to, but excluding, the Maturity Date or any earlier
redemption date (the “Floating Rate Period”). The floating interest rate will be reset quarterly, and the interest
rate for any Floating Rate Period will be equal to the then-current Benchmark plus 235 basis points. During the Floating Rate Period,
interest on this Note will be payable quarterly in arrears on February 15, May 15, August 15 and November 15 of each year (each such date,
a “Floating Rate Interest Payment Date”, and together with a Fixed Rate Interest Payment Date, an “Interest
Payment Date”), with the first such Floating Rate Interest Payment Date being November 15, 2026, and the last such Floating
Rate Interest Payment Date being the Maturity Date or any earlier redemption date. Notwithstanding the foregoing, if the Benchmark is
less than zero, the Benchmark shall be deemed to be zero. Interest on each Fixed Rate Interest Payment Date is payable to holders of record
on February 1 and August 1 of each year (whether or not a Business Day), commencing February 1, 2022 to and including August 1, 2026 (each,
a “Fixed Rate Regular Record Dates”). Interest on each Floating Rate Interest Payment Date is payable to holders of
record on February 1, May 1, August 1 and November 1 of each year (whether or not a Business Day) commencing November 1, 2026 (each, a
“Floating Rate Regular Record Dates”, and together with the Fixed Rate Regular Record Date, the “Record Dates”).


 


The 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,
August 15, 2026. The 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 number of days actually elapsed. If a Fixed Rate Interest Payment Date or the Maturity Date for this Note
falls on a day that is not a Business Day, the interest payable on such Interest Payment Date or the payment of principal and interest
on the Maturity Date will be paid on the next succeeding Business Day, but the payments made on such dates will be treated as being made
on the date that the payment was first due and the Holder of this Note will not be entitled to any further interest or other payment.
If a Floating Rate Interest Payment Date falls on a day that is not a Business Day, then such Floating Rate Interest Payment Date will
be postponed to the next succeeding Business Day, unless such day falls in the next succeeding calendar month, in which case 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.


 


For Notes held in definitive form, payments of interest
may be made, at the Company’s option, by (i) mailing a check for such interest payable to or upon the written order of the Person
entitled thereto, to the address of such Person as it appears on the Security Register or (ii) transfer to an account maintained by the
payee located inside the United States. For Notes held in global form, payments shall be made through the Depository, or its nominee,
as the registered owner of the Notes. All such payments shall be 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.


 






    	 	A-5	 



     


    

 


2.Paying Agent and Registrar.
Initially, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar
without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.


 


3.Indenture. This Note
is one of the 2.875% Fixed-to-Floating Rate Senior Notes due 2031 (the “Notes”) issued under the Indenture, dated as
of July 30, 2013 (as amended, modified or supplemented from time to time in accordance therewith, other than with respect to a particular
series of debt securities, the “Base Indenture” and, as amended, modified and supplemented by the Fourth Supplemental
Indenture, dated as of August 6, 2021, the “Indenture”), by and between the Company and the Trustee. This Note is a
“Global Security” and the Notes are “Global Securities” under the Indenture. The terms of the Notes
include those stated in the Indenture and those made part of the Indenture by reference to the TIA as in effect on the date on which the
Indenture was qualified under the TIA. The Notes are subject to all such terms, and Holders of the Notes are referred to the Indenture
and the TIA for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture,
the provisions of the Indenture shall govern and be controlling.


 


4.Optional Redemption.
The Notes are redeemable, in whole or in part, at the option of the Company, beginning with the Interest Payment Date on August 15, 2026,
and on any Floating Rate Interest Payment Date thereafter (each, a “Redemption Date”) at a redemption price equal to
100% of the principal amount of the Notes plus accrued and unpaid interest to, but excluding, the Redemption Date. On and after the Redemption
Date, interest shall cease to accrue on the Notes or the portions thereof called for redemption. In addition to the Company’s right
to redeem the Notes as provided in the Indenture, the Company may at any time and from time to time purchase Notes in open market transactions,
tender offers or otherwise.


 


5.Notice of Redemption.
In the event of any redemption of the Notes, we will deliver or cause to be delivered a notice of redemption by first class mail, or in
the event the notes are represented by global Notes, electronically in accordance with the procedures of The Depository Trust Company
(“DTC”) at least 30 days but not more than 60 days before the Redemption Date to each Holder whose Notes are to be
redeemed at its registered address; provided that redemption notices may be mailed more than 60 days prior to a Redemption Date if the
notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. Notes in denominations
larger than $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed.
Notes to be redeemed shall, on the Redemption Date, become due and payable at the redemption price. The Company shall deposit with the
Trustee or with the Paying Agent, one Business Day prior the Redemption Date, money sufficient to pay the redemption price on all Notes
to be redeemed on that date.


 


6.Denominations, Transfer,
Exchange. The Notes are in registered form without coupons in minimum denominations of $1,000 and integral multiples of $1,000 in
excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the
Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require
a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company and the Registrar need not exchange or register
the transfer of any Note selected for redemption, in whole or in part, except for the unredeemed portion of any Note being redeemed in
part. The Company need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed
or during the period between a record date and the next succeeding Interest Payment Date.


 


7.No Sinking Fund. There
is no sinking fund provided for the Notes.


 


8.Persons Deemed Owners.
The registered Holder of a Note shall be treated as the owner of it for all purposes.


 


9.Amendment, Supplement and
Waiver. The Base Indenture permits, with certain exceptions as therein provided, the Company and the Trustee to enter into one or
more supplemental indentures without notice to any Holder but with the written consent of the Holders of a majority in principal amount
of the Securities of each Series then outstanding (including consents obtained in connection with a tender offer or exchange for the Securities)
affected by such supplemental indenture. In addition, the Base Indenture permits the Company and the Trustee to enter into one or more
supplemental indentures without the consent of any Holder for certain specified purposes as therein provided, including: to cure any ambiguity,
defect or inconsistency contained in the Base Indenture, in any supplemental indenture or
in any Securities; to provide for uncertificated Securities in addition to or in place of certificated Securities; to
make any change that would provide any additional rights or benefits to the Holders of Securities or that does not adversely affect the
legal rights under the Indenture of any such Holder; to evidence the succession of another Person to the Company pursuant to Article
V of the Base Indenture and the assumption by such successor of the Company’s covenants, agreements and obligations in the Base
Indenture and in the Securities; to modify the Base Indenture in such a manner to comply with the requirements of the SEC or as to permit
the qualification of the Base Indenture or any supplemental indenture under the TIA; to add any guarantor or to provide any collateral
to secure any Notes; to add additional obligors under the Indenture and the Securities; to evidence and provide for the acceptance of
appointment by a successor Trustee with respect to the Securities and matters related thereto; or to establish the form or terms of Securities
of any Series pursuant to Section 2.2 of the Base Indenture. The Indenture also contains provisions permitting the Holders of specified
percentages in principal amount of the Securities of each Series at the time outstanding, on behalf of the Holders of all Securities of
such Series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture
and their consequences. Any such consent or waiver by the Holder of this 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 herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Note.


 






    	 	A-6	 



     


    

 


10.Defaults and Remedies.
If an Event of Default occurs and is continuing, the principal amount of the Notes, together with accrued interest to the date of declaration,
may be declared to be due and payable immediately in the manner and with the effect provided in the Indenture. Holders of Notes may not
enforce the Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes
unless it has received indemnity satisfactory to it. The Indenture permits, subject to certain limitations therein provided, Holders of
a majority in aggregate principal amount of the Notes then outstanding to direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Holders of Notes notice of certain continuing Defaults or Events of Default if it determines that withholding
notice is in their interest.


 


11.Trustee Dealings with Company.
The Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Company
or any Affiliate of the Company with the same rights it would have if it were not the Trustee.


 


12.Discharge and Defeasance.
Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Notes and
the Indenture if the Company deposits with the Trustee cash in United States dollars, non-callable U.S.
Government Obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized
firm of independent public accountants, to pay and discharge the entire indebtedness on the outstanding Notes for principal and accrued
interest, to the date of maturity or redemption, as the case may be.


 


13.No Recourse Against Others.
No recourse under or upon any obligation, covenant or agreement contained in the Indenture or in this Note, or for any claim based thereon
or otherwise in respect thereof, shall be had against any incorporator, shareholder, employee, officer, or director, as such, past, present
or future, of the Company, either directly or through the Company, whether by virtue of any constitution, statute or rule of law, or by
the enforcement of any assessment or penalty or otherwise; it being expressly understood that the Indenture, this Note and the obligations
issued hereunder are solely obligations of the Company, and that no such personal liability whatever shall attach to, or is or shall be
incurred by, the incorporators, shareholders, employees, officers or directors, as such, of the Company, or any of them, because of the
creation of the indebtedness hereby authorized, or under or by reason of the obligations, covenants or agreements contained in the Indenture
or in any Note or implied therefrom; and that any and all such personal liability of every name and nature, either at common law or in
equity or by constitution or statute or otherwise, of, and any and all such rights and claims against, every such incorporator, shareholder,
employee, officer or director, as such, because of the creation of the indebtedness hereby authorized, or under or by reason of the obligations,
covenants or agreements contained in the Indenture or in any Note or implied therefrom, are hereby expressly waived and released as a
condition of, and as a consideration for the issuance of the Notes.
