ARTICLE 2

ESTABLISHMENT OF THE 2030 SERIES AND

GENERAL TERMS AND CONDITIONS OF THE NOTES

Section 2.01 Establishment of the Series of the Notes and Designation. There is hereby
authorized and established a Series of Securities designated as the “6.00% Fixed to Floating Rate
Subordinated Notes due April 15, 2030.” The Securities that are a part of such Series of Securities
shall be in the form and have the terms, provisions and conditions as set forth in the Base
Indenture, this First Supplemental Indenture and the Notes in the form attached hereto as
Exhibit A.

Section 2.02 Maturity. The date upon which the entire principal amount of the Notes shall
become due and payable, together with any accrued and unpaid interest then owing, which shall be
the earlier of April 15, 2030 or the date on which principal becomes due as a result of an
acceleration under Section 2.07 of this First Supplemental Indenture (the “Maturity Date”).

Section 2.03 Form, Payment and Appointment. Except as provided in the eighth paragraph of
Section 3.05 of the Base Indenture, the Notes will be issued only in book-entry form, will be
represented by one or more Global Notes (as defined below) registered in the name of or held by The
Depository Trust Company (and any successor thereto) (“DTC”) or its nominee. Principal or the
Redemption Price, if any, of a Note shall be payable to the Person in whose name that Note is
registered on the Maturity Date or Redemption Date, as the case may be, provided that principal of,
the Redemption Price, if any, of and interest on the Notes represented by one or more Global Notes
(as hereinafter defined) registered in the name of or held by DTC or its nominee will be payable in
immediately available funds to DTC or its nominee, as the case may be, as the registered holder of
such Global Notes. The principal of any certificated Notes will be payable at the Place of Payment;
provided, however, that payment of interest may be made at the option of the Company through the
Paying Agent by check mailed to the Person entitled thereto at such address as shall appear in the
Security Register or by wire transfer to an account appropriately designated by the Person entitled
to payment; provided that the Paying Agent shall have received written notice of such account
designation at least five Business Days prior to the date of such payment (subject to surrender of
the relevant Note in the case of a payment of interest on the Maturity Date).

The Notes shall have such other terms as are set forth in the form thereof attached hereto as
Exhibit A.

The Security Registrar, Authenticating Agent and Paying Agent for the Notes shall initially be
the Trustee.

The Notes will be issuable and may be transferred only in minimum denominations of $1,000 or
an integral multiple of $1,000 in excess thereof. The amounts payable with respect to the Notes
shall be payable in U.S. Dollars.

Section 2.04 Global Note. The Notes shall be issued initially in the form of one or more fully
registered global notes (each such global note, a “Global Note”) registered in the name of DTC or
its nominee and deposited with the Trustee, as custodian for DTC. Unless and until a Global Note is
exchanged for Notes in certificated form, such Global Note may be transferred, in whole but not in
part, and any payments on the Notes shall be made, only to DTC or a nominee of DTC, or to a
successor Depositary selected or approved by the Company or to a nominee of such successor
Depositary as provided in the Indenture.

Section 2.05 Interest.

(a) Interest payable on any Interest Payment Date, the Maturity Date or the Redemption Date,
if any, with respect to the Notes shall be the amount of interest accrued from, and including, the
immediately preceding Interest Payment Date in respect of which interest has been paid or duly
provided for (or from and including the initial original issue date of Notes of the 2030 Series, if
no interest has previously been paid or duly provided for with respect to any of the Notes of the
2030 Series) to, but excluding, such Interest Payment Date, Maturity Date or the Redemption Date,
if any, as the case may be (each, an “Interest Period”).

(b) From and including the initial original issue date of the Notes of the 2030 Series to but
excluding April 15, 2025 the fixed rate at which the Notes shall bear interest shall be 6.00% per
annum, computed on the basis of a 360-day year consisting of twelve 30-day months, and payable
semi-annually in arrears; from and including April 15, 2025 to but excluding the Maturity Date, the
rate at which the Notes shall bear interest shall be a floating rate equal to LIBOR determined on
the determination date of the applicable Interest Period plus a spread of 3.944%, computed on the
basis of a 360-day year and the actual number of days elapsed, and payable quarterly in arrears
(the “Floating Rate Period”). The date from which interest shall accrue on the Notes shall be April
15, 2015 or the most recent Interest Payment Date to which interest has been paid or duly provided
for; the Interest Payment Dates for the Notes shall be April 15 and October 15 of each year through
April 15, 2025, and thereafter January 15, April 15, July 15 and October 15 of each year through
the Maturity Date or earlier Redemption Date (each such payment date, an “Interest Payment Date”).
In the event that any scheduled Interest Payment Date for the Notes falls on a day that is not a
Business Day, then payment of interest payable on such Interest Payment Date will be postponed to
the next succeeding day which is a Business Day (and no interest on such payment will accrue for
the period from and after such scheduled Interest Payment Date) except that, in the case of any
Floating Rate Period, if such business day is in the next succeeding calendar month, interest will
be payable on the immediately preceding business day, and no interest will accrue or fail to accrue
as a result of that postponement or earlier payment.

(c) In the event that the Maturity Date for any Note falls on a day that is not a Business
Day, then the related payments of principal of, and interest on, the Notes may be made on the next
succeeding day that is a Business Day (and no additional interest will accrue on the amount payable
for the period from and after the Maturity Date). Interest due on the Maturity Date (whether or not
an Interest Payment Date) of any Notes will be paid to the Person to whom principal of such Notes
is payable.

Section 2.06 Subordination.

(a) The Company, for itself, its successors and assigns, covenants and agrees, and each Holder
of Notes by the Holder’s acceptance thereof, likewise covenants and agrees, that the payment of the
principal of and interest on each and all of the Notes is and will be expressly subordinated in
right of payment to the prior payment in full of all Senior Debt, subject to clause (j) of this
Section 2.06, to the extent and in the manner described in this Section 2.06 and Section 14.01 of
the Base Indenture. The Company shall give prompt written notice to the Trustee upon the incurrence
of any Senior Debt as well as the representative for such Senior Debt (each identified
representative, an “Identified Representative”).

(b) Upon any distribution of assets of the Company upon any termination, winding up,
liquidation or reorganization of the Company, whether in bankruptcy, insolvency, reorganization or
receivership proceedings or upon an assignment for the benefit of creditors or any other
marshalling of the assets and liabilities of the Company or otherwise (subject to the power of a
court of competent jurisdiction to make other equitable provision reflecting the rights conferred
upon the Senior Debt and the holders thereof with respect to the Notes and the Holders thereof by a
lawful plan of reorganization under applicable bankruptcy law):

(i) the holders of all Senior Debt shall first be entitled to receive payment in full in
accordance with the terms of such Senior Debt of the principal thereof, premium, if any, and the
interest due thereon (including interest accruing subsequent to the commencement of any proceeding
for the bankruptcy or reorganization of the Company under any applicable bankruptcy, insolvency or
similar law now or hereafter in effect) before the Holders of the Notes are entitled to receive any
payment upon the principal of or interest on indebtedness evidenced by the Notes;

(ii) any payment or distribution of assets of the Company of any kind or character, whether in
cash, property or securities, to which the Holders of the Notes would be entitled except for the
provisions of Section 14.01 of the Base Indenture and this Section 2.06, including any such payment
or distribution that may be payable or deliverable by reason of the payment of any other
indebtedness of the Company being subordinated to the payment of the Notes, shall be paid by the
liquidating trustee or agent or other Person making such payment or distribution, whether a trustee
in bankruptcy, a receiver or liquidating trustee or otherwise, directly to the holders of Senior
Debt or their representative or representatives (including any Identified Representatives) or to
the trustee or trustees under any indenture under which any instruments evidencing any of such
Senior Debt may have been issued, in accordance with the priorities then existing among holders of
Senior Debt for payment of the aggregate amounts remaining unpaid on account of the principal,
premium, if any, and interest (including interest accruing subsequent to the commencement of any
proceeding for the bankruptcy or reorganization of the Company under any applicable bankruptcy,
insolvency or similar law now or hereafter in effect) on the Senior Debt held or represented by
each, to the extent necessary to make payment in full of all Senior Debt remaining unpaid, after
giving effect to any concurrent payment or distribution to the holders of such Senior Debt; it
being understood that if the Holders of the Notes shall fail to file a proper claim in the form
required by any proceeding referred to in this subparagraph (ii) prior to 30 days before the
expiration of the time to file such claim or claims, then the holders of Senior Debt are hereby
authorized to file an appropriate claim or claims for and on behalf of the Holders of the Notes, in
the form required in any such proceeding; and

(iii) in the event that, notwithstanding the foregoing, any payment or distribution of assets
of the Company of any kind or character, whether in cash, property or securities, including any
such payment or distribution that may be payable or deliverable by reason of the payment of any
other indebtedness of the Company being subordinate to the payment of the Notes shall be received
by the Trustee or Holders of the Notes before all Senior Debt is paid in full, such payment or
distribution shall be paid over as described in the following paragraph until all such Senior Debt
shall have been paid in full.

Subject to the payment in full of all Senior Debt, the Holders of the Notes shall be
subrogated to the rights of the holders of Senior Debt to receive payments or distributions of
cash, property or securities of the Company applicable to the Senior Debt until the principal of
and interest on the Notes shall be paid in full and no such payments or distributions to holders
of such Senior Debt to which the Holders of the Notes would be entitled except for the provisions
hereof of cash, property or securities otherwise distributable to the holders of Senior Debt shall,
as between the Company, its creditors, other than the holders of Senior Debt, and the Holders of
the Notes, be deemed to be a payment by the Company to or on account of the Senior Debt. It is
understood that the provisions of this Section 2.06 are intended solely for the purpose of defining
the relative rights of the Holders of the Notes, on the one hand, and the holders of Senior Debt,
on the other hand, and, in the case of clause (j) of this Section 2.06, the holders of Existing
Company Subordinated Indebtedness. Nothing contained in this Section 2.06 or elsewhere in the Base
Indenture, this First Supplemental Indenture or any supplemental indenture issued pursuant to
Section 3.01 or Article Nine of the Base Indenture or in the Notes is intended to or shall impair,
as between the Company, its creditors, other than the holders of Senior Debt, and the Holders of
the Notes, the obligation of the Company, which is unconditional and absolute, to pay to the
Holders of the Notes the principal of and interest on the Notes as and when the same shall become
due and payable in accordance with their terms or to affect the relative rights of the Holders of
the Notes and creditors of the Company, other than the holders of the Senior Debt, nor, except as
otherwise expressly provided in the Base Indenture, this First Supplemental Indenture and the Notes
with respect to the limitation on the rights of the Trustee and the Holders of Notes, to accelerate
the maturity of the Notes and pursue remedies upon such an acceleration, shall anything herein or
in the Notes prevent the Trustee or the Holder of any Notes from exercising all remedies otherwise
permitted by applicable law upon any Event of Default under the Indenture occurring, subject to the
rights, if any, under this Section 2.06 of the holders of Senior Debt, in respect of cash, property
or securities of the Company received upon the exercise of any such remedy. Upon any payment or
distribution of assets of the Company referred to in this Section 2.06(b), the Trustee and the
Holders of the Notes shall be entitled to rely upon any order or decree of a court of competent
jurisdiction in which such termination, winding up, liquidation or reorganization proceeding is
pending or upon a certificate of the liquidating trustee or agent or other Person making any
distribution to the Trustee or to the Holders of the Notes (such party, a “Liquidating Agent”) for
the purpose of ascertaining the Persons entitled to participate in such distribution, the holders
of the Senior Debt and other indebtedness of the Company, the amount hereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this
Section 2.06. In the absence of any such certificate from a Liquidating Agent, the Trustee shall
rely upon a written notice from an Identified Representative as to the distributions to be made
with respect to the Senior Debt. If a Person that is not an Identified Representative or a party
identified by the Liquidating Agent claims to be a holder of Senior Debt (or a trustee or
representative on behalf of such holder) (such Person, a “Claiming Representative”) the Trustee may
defer any payments to all parties, including any Identified Representative and Claiming
Representatives, pending judicial determination as to the right of the Persons to receive such
payment.

With respect to the holders of Senior Debt (including any agent thereof, any Identified
Representative or any Claiming Representative), the Trustee undertakes to perform or to observe
only such of its covenants and obligations as are specifically set forth in this Section 2.06, and
no implied covenants or obligations with respect to the holders of Senior Debt (including any agent
thereof, any Identified Representative or any Claiming Representative)shall be read into this
Section 2.06 against the Trustee. The Trustee, however, shall not be deemed to owe any fiduciary
duty to the holders of Senior Debt (including any agent thereof, any Identified Representative or
any Claiming Representative)by reason of the execution of the Base Indenture, this First
Supplemental Indenture, or any other supplemental indenture entered into pursuant to Section 3.01
or Article Nine of the Base Indenture, and shall not be liable to any such holders if it shall pay
over or distribute to or on behalf of Holders of the Notes or the Company moneys or assets to which
any holders of Senior Debt shall be entitled by virtue of this Section 2.06.

(c) In the event and during the continuation of any default in the payment of principal of, or
premium, if any, or interest on, any Senior Debt, beyond any applicable period of grace, or if any
event of default with respect to any Senior Debt shall have occurred and be continuing, or would
occur as a result of the payment referred to hereinafter, permitting the holders of such Senior
Debt (or a trustee on behalf of the holders thereof) to accelerate the maturity thereof, then,
unless and until such default or event of default shall have been cured or waived or shall have
ceased to exist, no payment or principal of or interest on the Notes, or in respect of any
retirement, purchase or other acquisition of any of the Notes, shall be made by the Company. The
Trustee shall have no independent responsibility to determine whether such events exist that would
prohibit a payment on the Notes and may rely solely on the Company (or upon written notice from any
Identified Representative) with respect to any such determinations.

(d) Nothing contained in the Base Indenture, this First Supplemental Indenture, any other
supplemental indenture entered into pursuant to Section 3.01 or Article Nine of the Base
Indenture, or in any of the Notes shall: (i) impair, as between the Company and Holders of the
Notes, the obligations of the Company, to make, or prevent the Company from making, at any time
except as provided in clauses (b), (c), or (j) of this Section 2.06, payments of principal of, or
interest (including interest accruing subsequent to the commencement of any proceeding for the
bankruptcy or reorganization of the Company under any applicable bankruptcy, insolvency, or similar
law now or hereafter in effect) on, the Notes, as and when the same shall become due and payable in
accordance with the terms of the Notes; (ii) affect the relative rights of the Holders of the Notes
and creditors of the Company other than the holders of the Senior Debt; (iii) except as otherwise
expressly provided in the Base Indenture, this First Supplemental Indenture and the Notes with
respect to the limitation on the rights of the Trustee and the Holders of Notes, to accelerate the
maturity of the Notes and pursue remedies upon such an acceleration, prevent the Holder of any
Notes or the Trustee from exercising all remedies otherwise permitted by applicable law upon
default thereunder, subject to the rights, if any, under this Section 2.06 of the holders of Senior
Debt in respect of cash, property or securities of the Company received upon the exercise of such
remedy; or (iv) prevent the application by the Trustee or any Paying Agent of any moneys deposited
with it hereunder to the payment of or on account of the principal of, or interest on, the Notes or
prevent the receipt by the Trustee or any Paying Agent of such moneys, if, prior to the third
Business Day prior to such deposit, the Trustee or such Paying Agent did not have written notice
from the Company or any Identified Representative of any event prohibiting the making of such
deposit by the Company.

(e) Each Holder by his acceptance of any Notes authorizes and expressly directs the Trustee on
such Holder’s behalf to take such action as may be necessary or appropriate to effectuate the
subordination provided in the Indenture, and appoints the Trustee such Holder’s attorney-in- fact
for such purposes, including, in the event of any termination, winding up, liquidation or
reorganization of the Company (whether in bankruptcy, insolvency, receivership, reorganization or
similar proceedings or upon an assignment for the benefit of creditors by the Company, a
marshalling of the assets and liabilities of the Company or otherwise) tending toward the
liquidation of the property and assets of the Company, the filing of a claim for the unpaid balance
of the Notes in the form required in those proceedings.

The Company shall give prompt written notice to the Trustee of any fact known to the Company
that would prohibit the Company from making any payment to or by the Trustee in respect of the
Notes pursuant to the provisions of this Section 2.06 or Article Fourteen of the Base Indenture.
The Trustee shall not be charged with the knowledge of the existence of any default or event of
default with respect to any Senior Debt or of any other facts that would prohibit the making of any
payment to or by the Trustee unless and until a Responsible Officer of the Trustee shall have
received notice in writing at its Corporate Trust Office to that effect signed by an Officer of the
Company, or by an Identified Representative, the Trustee shall be entitled to assume that no such
facts exist; provided that, if the Trustee shall not have received the written notice provided for
in this Section 2.06 at least three Business Days prior to the date upon which, by the terms of the
Indenture, any monies shall become payable for any purpose (including, without limitation, the
payment of the principal of or interest on any Note), then, notwithstanding anything herein to the
contrary, the Trustee shall have full power and authority to receive any monies from the Company
and to apply the same to the purpose for which they were received, and shall not be affected by any
notice to the contrary that may be received by it on or after such prior date except for an
acceleration of the Notes prior to such application. The foregoing shall not apply if the Paying
Agent is the Company. The Trustee shall be entitled to rely without further investigation on the
delivery to it of a written notice by an Identified Representative to establish that such notice
has been given by a holder of such Senior Debt or a trustee or agent on behalf of any such holder.

In the event that the Trustee determines in good faith that any evidence is required with
respect to the right of any Claiming Representative as a holder of Senior Debt to participate in
any payment or distribution pursuant to this Section 2.06 or Article Fourteen of the Base
Indenture, the Trustee may request such Claiming Representative to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Debt 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 Section 2.06 or Article Fourteen of
the Base Indenture and, if such evidence is not furnished to the Trustee, the Trustee may defer any
payment to such Person pending such evidence being furnished to the Trustee or a judicial
determination that such Claiming Representative has the right to receive such payment.

(f) Notwithstanding the provisions of this Section 2.06 or any other provisions of the Base
Indenture, this First Supplemental Indenture or any other supplemental indenture issued pursuant to
Section 3.01 or Article Nine of the Base Indenture, neither the Trustee nor any Paying Agent shall
be charged with knowledge of the existence of any Senior Debt or of any event that would prohibit
the making of any payment or moneys to or by the Trustee or such Paying Agent, unless and until a
Responsible Officer of the Trustee or such Paying Agent shall have received written notice thereof
from the Company or from the holder of any Senior Debt or from the representative of any such
holder.

(g) The Trustee shall be entitled to all of the rights set forth in this Section 2.06 in
respect of any Senior Debt at any time held by it in its individual capacity to the same extent as
any other holder of such Senior Debt, and nothing in the Base Indenture, this First Supplemental
Indenture or any other supplemental indenture issued pursuant to Section 3.01 or Article Nine of
the Base Indenture shall be construed to deprive the Trustee of any of its rights as such holder.

(h) The failure to make a payment pursuant to the Notes by reason of any provision in this
Section 2.06 shall not be construed as preventing the occurrence of a Default or any Event of
Default.

(i) Nothing contained in this Section 2.06 shall apply to the claims of, or payments to, the
Trustee under or pursuant to Section 6.07 of the Base Indenture. Similarly, the Trustee shall be
entitled to exercise its charging lien granted pursuant to Section 6.07 of the Base Indenture on
any funds received before application of the subordination provisions of this Section 2.06.

(j) Subject to the provisions of this clause (j) of Section 2.06 and to any provisions
established or determined with respect to Securities of any Series pursuant to Section 3.01 of the
Base Indenture, the Notes shall rank pari passu in right of payment with the Existing Company
Subordinated Indebtedness. Upon the occurrence of any of the events specified in clause (b) of this
Section 2.06, the provisions of that clause and the corresponding provisions of each indenture or
other instrument or document establishing or governing the terms of any Existing Company
Subordinated Indebtedness shall be given effect on a pro rata basis to determine the amount of
cash, property or securities that may be payable or deliverable as between the holders of Senior
Debt, on the one hand, and the Holders of the Notes and holders of Existing Company Subordinated
Indebtedness, on the other hand.

(k) The subordination provisions in this Section 2.06 or Article Fourteen of the Base
Indenture do not apply to amounts due to the Trustee pursuant to other sections of the Indenture,
including Section 6.07 of the Base Indenture.

Section 2.07 Events of Default; Acceleration. All of the Events of Default set forth in
clauses (1), (2), (4) and (5) of Section 5.01 of the Base Indenture will apply with respect to the
Notes and clause (3) of Section 5.01 of the Base Indenture shall not apply with respect to the
Notes. Notwithstanding the foregoing, because the Company will treat the Notes as Tier 2 capital
(or its then equivalent if the Company were subject to such capital requirement) for purposes of
capital adequacy guidelines of the Federal Reserve Board as then in effect and applicable to the
Company, upon the occurrence of an Event of Default other than an Event of Default set forth in
clause (4) or (5) of Section 5.01 of the Base Indenture, neither the Trustee nor the Holders of the
Notes may accelerate the Maturity of the Notes and make the principal of, and any accrued and
unpaid interest on, the Notes, immediately due and payable. If an Event of Default specified in
clause (4) or (5) of Section 5.01 of the Base Indenture occurs, then the principal amount
of all of the outstanding Notes, including any accrued and unpaid interest on the Notes and
premium, if any, shall become and be immediately due and payable without any declaration or other
act on the part of the Trustee or the Holders of the Notes.

Section 2.08 No Sinking Fund. The Notes are not entitled to the benefit of any sinking fund.

Section 2.09 No Conversion or Exchange Rights. The Notes shall not be convertible into or
exchangeable for any equity securities, other securities or other assets of the Company or any
Subsidiary.

Section 2.10 No Defeasance or Covenant Defeasance. Sections 13.02 and 13.03 of the Base
Indenture shall not be applicable to the Notes.

ARTICLE 3

REDEMPTION OF THE NOTES

Section 3.01 Redemption. The Company may, at its option, by notice to the Holders of Notes and
the Trustee, redeem the Notes, in whole or in part, on any Interest Payment Date on or after April
15, 2025. The Company may also, at its option, redeem the Notes before the Maturity Date in whole,
at any time, upon the occurrence of a Tier 2 Capital Event or a Tax Event or if the Company is
required to register as an investment company pursuant to the Investment Company Act of 1940 (15
U.S.C. 80a-1 et seq.). Any such redemption will be at a Redemption Price equal to the principal
amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the
Redemption Date fixed by the Company, provided that, for avoidance of doubt, the payment of such
accrued and unpaid interest paid as a part of the Redemption Price shall satisfy in full the
obligation of the Company to pay accrued and unpaid interest on the Notes redeemed from and
including the most recent Interest Payment Date on which all accrued and unpaid interest on the
Notes was paid or provided for through, but excluding, the Redemption Date. No such redemption of
the Notes by the Company prior to the Maturity Date shall be made without the prior approval of the
Federal Reserve Board if such prior approval is or will be required at the scheduled Redemption
Date in order for the Notes to qualify as Tier 2 capital of the Company under the rules and
guidelines of the Federal Reserve Board. The provisions of Article Eleven of the Base Indenture
shall apply to any redemption of the Notes pursuant to this Article 3.

ARTICLE 4

FORM OF NOTES

Section 4.01 Form of Notes. The Notes and the Trustee’s Certificate of Authentication thereon
are to be substantially in the form attached as Exhibit A hereto, with such changes therein
as the officers of the Company executing the Notes (by manual or facsimile signature) may approve,
such approval to be conclusively evidenced by their execution thereof.

ARTICLE 5

ISSUE OF NOTES

Section 5.01 Original Issue of Notes. Notes having an aggregate principal amount of
$40,000,000 may from time to time, upon execution of this First Supplemental Indenture, be executed

authenticate and deliver said Notes in accordance with a Company Order pursuant to Section 3.03 of
the Base Indenture without any further action by the Company (other than as required by the Base
Indenture).

Section 5.02 Additional Issues of Notes. The Company may from time to time, without notice to
or the consent of the Holders of the Notes, issue additional Notes, which Notes will rank pari
passu with the Notes and be identical in all respects as the Notes previously issued except for
their issuance date, the offering price, the payment of interest accruing prior to the issue date
of such additional Notes and the first payment of interest following the issue date of such
additional Notes in order that such additional Notes may be consolidated and form a single Series
with the Notes outstanding immediately prior to the issuance of such additional Notes and have the
same terms as to status, redemption or otherwise as the Notes; provided, that if any additional
Notes are not fungible with the initial Notes for U.S. income tax purposes, such additional Notes
will have a separate CUSIP number.

ARTICLE 6

IMMUNITY OF STOCKHOLDERS, EMPLOYEES, AGENTS, OFFICERS AND DIRECTORS

Section 6.01 Indenture and Notes Solely Corporate Obligations. No recourse for the payment of
the principal of or interest on any Note, or for any claim based thereon or otherwise in respect
thereof, shall be had against any incorporator, shareholder, officer, director, employee or agent,
as such, past, present or future, of the Company or of any successor Person to the Company, it
being expressly understood that all such liability is hereby expressly waived and released as a
condition of, and as a consideration for, the execution of this First Supplemental Indenture and
the issue of the Notes.

REVERSE OF NOTE

FINANCIAL INSTITUTIONS, INC.

6.00% Fixed to Floating Rate Subordinated Notes due April 15, 2030

This Note is one of a duly authorized issue of Securities of the Company of a Series
designated as the “6.00% Fixed to Floating Rate Subordinated Notes due April 15, 2030” (herein
called the “Notes”) initially issued in an aggregate principal amount of $40,000,000 on April 15,
2015. Such Series of Securities has been established pursuant to, and is one of an indefinite
number of Series of subordinated debt securities of the Company issued or issuable under and
pursuant to, the Subordinated Debt Indenture (the “Base Indenture”), dated as of April 15, 2015,
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 April 15, 2015, thereto
(the “First Supplemental Indenture” and the Base Indenture as supplemented and amended by the First
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 on the Security Register 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, 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 the Indenture shall govern to the
extent such terms, conditions and other provisions of the Indenture are not inconsistent with the
terms, conditions and provisions made part of the Indenture by reference to the Trust Indenture Act
of 1939, as amended.

All capitalized terms used in this Note and not defined herein that are defined in the Base
Indenture or the First Supplemental Indenture shall have the meanings assigned to them in the Base
Indenture or the First Supplemental Indenture. If any capitalized term used in this Note and
defined herein is also defined in the Base Indenture or the First Supplemental Indenture, in the
event of any conflict in the meanings ascribed to such capitalized term, the definition of the
capitalized term in this Note shall control.

The indebtedness of the Company evidenced by the Notes, including the principal thereof and
interest thereon, is, to the extent and in the manner set forth in the First Supplemental
Indenture, subordinate and junior in right of payment to obligations of the Company constituting
the Senior Debt (as defined in the Indenture) on the terms and subject to the terms and conditions
as provided and set forth in Section 2.06 of the First Supplemental Indenture and shall rank pari
passu in right of payment with all other Notes and with all other unsecured subordinated
indebtedness of the Company issued under the Indenture and not by its terms subordinate and junior
in right of payment to the promissory notes, bonds, debentures or other evidences of indebtedness
of types that include the Notes. Each Holder of this Security, by the acceptance hereof, agrees to
and shall be bound by such provisions of the Indenture and pursuant to Section 2.06 of the First
Supplemental Indenture 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 guidelines of the Board
of Governors of the Federal Reserve System (or any successor regulatory authority with jurisdiction
over bank holding companies) (the “Federal Reserve Board”) as then in effect and applicable to the
Company. 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 Section 2.07 of the First Supplemental Indenture. Accordingly, the holder
of this Note has no right to accelerate the maturity of this Note in the event the Company fails to
pay interest on any of the Notes, 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, by notice to the Holders of Notes and the Trustee, redeem the
Notes, in whole or in part, on any Interest Payment Date on or after April 15, 2025. The Company
may also redeem the Notes before the Scheduled Maturity Date upon the occurrence of a Tier 2
Capital Event or a Tax Event or if the Company is required to register as an investment company
pursuant to the Investment Company Act of 1940 (15 U.S.C. 80a-1 et seq.). Any such redemption will
be at a Redemption Price equal to the principal amount of the Notes to be redeemed, plus accrued
and unpaid interest to, but excluding, the Redemption Date fixed by the Company. No such redemption
of the Notes by the Company prior to the Scheduled Maturity Date shall be made without the prior
approval of the Federal Reserve Board if such prior approval is or will be required at the
scheduled Redemption Date in order for the Notes to qualify as Tier 2 Capital of the Company under
the rules and guidelines of the Board of Governors of the Federal Reserve System.

The Notes of this Series are not entitled to the benefit of any sinking fund. The Notes are
not convertible into or exchangeable for any of the equity securities, other securities or assets
of the Company or any Subsidiary.

The Base Indenture provisions relating to defeasance and covenant defeasance in Sections 12.02
and 12.03 of the Base Indenture shall not be applicable to the Notes.

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 a majority in
principal amount of the Notes of each Series (each Series voting as a class) (including any
consents obtained in connection with a tender offer) affected thereby and at the time Outstanding.
The Indenture also contains provisions permitting the Holders of specified percentages in principal
amount of the Notes of a Series at the time Outstanding, on behalf of the Holders of all Notes of
such Series, 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 herefor 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 Security Register, 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 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 this
Series, of authorized denominations and for the same aggregate principal amount, will be issued to
the designated transferee or transferees.

The Notes of this Series are issuable only in registered form without coupons in minimum
denominations of $1,000 and any integral multiple 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.

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

[Note: The provisions below that appear in brackets will be inserted into any Global Note
representing Notes.] [This Security is a global note, represented by one or more permanent global
certificates registered in the name of the nominee of The Depository Trust Company (each a “Global
Note” and collectively, the “Global Notes”). Accordingly, unless and until it is exchanged for
individual certificates evidencing the Notes represented hereby, this Security 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 below, owners of beneficial interests in this Security will not be
entitled to have any individual certificates and will not be considered the owners or Holders
thereof under the Indenture.

Except in the limited circumstances set forth in Section 3.05 of the Base Indenture,
Participants and owners of beneficial interests in the Global Notes will not be entitled to receive
Securities in definitive form and will not be considered Holders of Notes. Neither the Company nor
the principal Paying Agent will be liable for any delay by the Depositary, its nominee or any
direct or indirect participant in identifying the beneficial owners of the related Notes. The
Company and the principal payment agent may conclusively rely on, and will be protected in relying
on, instructions from the Depositary or its nominee for all purposes, including with respect to the
registration and delivery, and the respective principal amounts, of the Notes to be issued.

Except as provided in Section 3.05 of the Base Indenture, beneficial owners of Global Notes
will not be entitled to receive physical delivery of Notes in definitive form and no Global Note
will be exchangeable except for another Global Note of like denomination and tenor to be
registered in the name of the Depositary or its nominee. Accordingly, each person owning a
beneficial interest in a Global Note must rely on the procedures of the Depositary and, if such
person is not a Participant, on the procedures of the Participant through which such person owns
its interest, to exercise any rights of a Holder under the Notes.

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

Wilmington Trust, National Association will act as the Company’s principal Paying Agent with
respect to the Notes through its Corporate Trust Office presently located at 1100 North Market
Street, Wilmington, Delaware 19890. The Company may at any time rescind the designation of a Paying
Agent, appoint a successor Paying Agent, or approve a change in the office through which any Paying
Agent acts.

Notices to the Holders of registered Notes will be given to such Holders at their respective
addresses in the Security Register will be deemed to have been given on the fourth weekday (being a
day other than Saturday or Sunday) after the date of mailing, or in the case of Global Notes,
electronic delivery in accordance with DTC’s applicable procedures. The Indenture contains
provisions setting forth certain conditions to the institution of proceedings by the Holders of
Notes with respect to the Indenture or for any remedy under the Indenture.

THIS NOTE SHALL BE DEEMED TO BE A CONTRACT MADE UNDER THE LAWS OF THE STATE OF NEW YORK, AND
FOR ALL PURPOSES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF SAID STATE.
