Form of Executive Restricted Stock Unit Agreement

 Exhibit 10.24 
 RESTRICTED STOCK UNIT AGREEMENT 
 UNDER THE CITRIX SYSTEMS, INC. 
 2005 EQUITY INCENTIVE PLAN 
 Name of Awardee: [Name]

 Award Date: October 1, 2007 
 Number of Restricted Stock
Units: [Number of shares] 
 Pursuant to the Citrix Systems, Inc. 2005 Equity Incentive Plan (the “Plan”), Citrix Systems, Inc.
(the “Company”) hereby grants an Award (as defined in the Plan) of Restricted Stock Units (as defined in the Plan) to the awardee named above (the “Awardee”). Upon execution of this agreement, the Awardee shall receive the number
of Restricted Stock Units specified above, subject to the restrictions and conditions set forth herein and in the Plan. 
  

	 	1.	Vesting. 

 No portion of this Award may be received
until such portion shall have vested. Except as otherwise provided herein, the Restricted Stock Units shall vest in accordance with Schedule 1 hereto, provided in each case that the Awardee is then, and since the Award Date has continuously
been, employed by the Company or its Affiliates. 
  

	 	2.	Issuance of Stock. 

 (a) Subject to determination of
attainment levels by the Compensation Committee, each vested Restricted Stock Unit entitles Awardee to receive one share of the Company’s Common Stock, par value $.001 per share (the “Stock”), upon issuance on each Vesting Date for
such Restricted Stock Unit. 
 (b) As soon as practicable after the Vesting Date, the Awardee’s name shall be entered as the stockholder
of record on the books and records of the Company with respect to the Shares of Stock underlying the Restricted Stock Units issued in accordance with Section 3(a) and upon compliance to the satisfaction of the Committee with all requirements
under applicable laws or regulations in connection with such issuance and with the requirements hereof and of the Plan. The determination of the Committee as to such compliance shall be final and binding on Awardee. 
 (c) Until such time as shares of Stock have been issued to Awardee pursuant to Section 3(b) above, and except as set forth in Section 3(d)
below regarding dividends and dividend equivalents, Awardee shall not have any rights as a holder of the shares of Stock underlying this Award including but not limited to voting rights. 
 (d) If on any date the Company shall pay any dividend on shares of Stock of the Company, the number of Restricted Stock Units credited to Awardee shall,
as of such date, be increased by an amount determined by the following formula: 
 W = (X multiplied by Y) divided by Z,
where: 
 W = the number of additional Restricted Stock Units to be credited to Awardee on such dividend payment date;

 X = the aggregate number of Restricted Stock Units (whether vested or unvested) credited to Awardee as of the record date
of the dividend; 
  

 Y = the cash dividend per share amount; and 
 Z = the Fair Market Value per share of Stock (as determined under the Plan) on the dividend payment date. 
 In the case of a dividend paid on Stock in the form of Stock, including without limitation a distribution of Stock by reason of a stock dividend, stock split or
otherwise, the number of Restricted Stock Units credited to Awardee shall be increased by a number equal to the product of (i) the aggregate number of Restricted Stock Units that have been awarded to Awardee through the related dividend record
date, and (ii) the number of shares of Stock (including any fraction thereof) payable as dividend on one share of Stock. In the case of a dividend payable in property other than shares of Stock or cash, the per share of Stock value of such
dividend shall be determined in good faith by the Board of Directors of the Company and shall be converted to additional Restricted Stock Units based on the formula above. Any additional Restricted Stock Units shall be subject to the vesting and
restrictions of this Agreement in the same manner and for so long as the Restricted Stock Units granted pursuant to this Agreement to which they relate remain subject to such vesting and restrictions, and shall be promptly forfeited to the Company
if and when such Restricted Stock Units are so forfeited. 
 3. Termination of Employment. If Awardee’s employment by the Company
or any of its Affiliates (as defined in the Plan) is voluntarily or involuntarily terminated for any reason (including death or disability), Awardee’s right in any Restricted Stock Units that are not vested shall automatically terminate upon
the effective date of such termination of employment with the Company and its Affiliates and such Restricted Stock Units shall be canceled as provided within the terms of the Plan and shall be of no further force and effect. In the event of such
termination, the Company, as soon as practicable following the effective date of termination shall issue shares of Stock to Awardee (or Awardee’s designated beneficiary or estate executor in the event of Awardee’s death) with respect to
any Restricted Stock Units which, as of the effective date of termination, have vested but for which shares of Stock had not yet been issued to Awardee. 
 4. Incorporation of Plan. Notwithstanding anything herein to the contrary, this Award shall be subject to and governed by all the terms and conditions of the Plan. Capitalized terms in this Agreement shall have
the meaning specified in the Plan, unless a different meaning is specified herein. 
 5. Transferability. This Agreement is personal
to Awardee, is non-assignable and is not transferable in any manner, by operation of law or otherwise, other than by will or the laws of descent and distribution. This Award is available, during Awardee’s lifetime, only to Awardee, and
thereafter, only to Awardee’s designated beneficiary. 
 6. Tax Withholding and Sale of Shares of Stock Pursuant to Rule 10b5-1.
Awardee shall, not later than the date on which the Award becomes a taxable event for Federal income tax purposes, pay to the Company any Federal, state, and local taxes required by law to be withheld on account of such taxable event. To satisfy in
full such minimum tax withholding obligation, Awardee hereby authorizes the Company to withhold from shares of Stock to be issued hereunder that number of shares of Stock that would satisfy the minimum required tax withholding amount due and to sell
such shares of Stock through a broker of the Company’s choosing (i.e., “sell to cover”). As of the date hereof, I certify that (a) I am currently unaware of any material, non-public information with respect to the Company, and
(b) this Agreement is entered into in good faith and not as part of a plan or scheme to evade the prohibitions of Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, or any other securities laws. While this Agreement is in effect, I
agree (i) not to enter into or alter any corresponding or hedging transaction or position with respect to the securities covered by this Agreement (including, without limitation, with respect to any securities convertible or exchangeable into
shares of Stock) and (ii) not to attempt to exercise any influence over how, when or whether to effect the withholding and sale of shares of Stock pursuant to this Section 7. 
 7. Tax Consequences. The Company makes no representation or warranty as to the tax treatment to the Awardee of Awardee’s receipt of the Award
or vesting of Restricted Stock Units or upon Awardee’s sale or other disposition of the Stock. The Awardee should rely on his or her own tax advisors for such advice.

	 	8.	Miscellaneous. 

 (a) Notice hereunder shall be given
to the Company at its principal place of business, and shall be given to the Awardee at the address set forth below, or in either case at such other address as one party may subsequently furnish to the other party in writing. 
 (b) This Agreement does not confer upon the Awardee any rights with respect to continuation of employment by the Company or any of its subsidiaries.

 (c) The Committee may amend the terms of this Agreement, prospectively or retroactively, provided that the Agreement as amended is
consistent with the terms of the Plan, but no such amendment shall impair the Awardee’s rights under this Agreement without the Awardee’s consent. 
 (d) This Agreement shall be construed and enforced in accordance with the laws of the State of Delaware, without regard to the conflict of laws principles thereof. 
 (e) This Agreement shall be binding upon and inure to the benefit of any successor or assign of the Company and any executor, administrator, trustee,
guardian or other legal representative of the Awardee. 
 (f) This Agreement may be executed in one or more counterparts, all of which
together shall constitute but one instrument. This Agreement and the Plan together constitute the entire agreement between the parties relative to the subject matter hereof, and supersede all proposals written or oral relating to the subject matter
hereof.

 (f) there shall have occurred a material adverse change in general domestic or international economic, political or
financial conditions, including without limitation as a result of terrorist activities, such that market trading in the Common Stock or Qualified Warrants has been materially disrupted;

counsel of an Affiliate of the Company but not an employee of the Company or such an Affiliate and must be reasonably acceptable to the Property Trustee) experienced in tax matters (which opinion shall not have been rescinded), to the effect that,

that: (i) if that release (or any successor release) is not published or does not contain that price information on that trading day; or (ii) if the Treasury Dealer determines that the price information is not reasonably reflective of the
actual bid-side price of the Treasury Security prevailing at 3:30 p.m., New York City time, on that trading day, then Treasury Price will instead mean the bid-side price for the Treasury Security at or around 3:30 p.m., New York City time, on that
trading day (expressed on a next trading day settlement basis) as determined by the Treasury Dealer through such alternative means as the Treasury Dealer considers to be appropriate under the circumstances.

 ARTICLE II 
 TERMS OF SERIES OF SECURITIES 
 Section 2.1. Pursuant to Sections 2.1 and 3.1 of the Indenture, there is hereby established a series of Securities, the terms of which shall be as follows: 
 (a) Designation. The Securities of this series shall be known and designated as the “8.000% Junior Subordinated Debentures due
March 15, 2068” of the Company (the “Debentures”). The Debentures initially shall be issued to KeyCorp Capital X, a Delaware statutory trust (the “Trust”). The Trust Agreement for the Trust shall be the Amended and
Restated Trust Agreement, dated as of February 27, 2008, among the Company, as Sponsor, Deutsche Bank Trust Company Delaware, as Delaware Trustee, Deutsche Bank Trust Company Americas, as Property Trustee, and the Administrative Trustees named
therein (the “Trust Agreement”). A Guarantee will be issued pursuant to the Guarantee Agreement, dated as of February 27, 2008, between the Company and Deutsche Bank Trust Company Americas, as Guarantee Trustee (the “Guarantee
Agreement”). The Trust Preferred Securities, as defined in this Supplemental Indenture, are the “Capital Securities” as defined in the Trust Agreement. 
 (b) Aggregate Principal Amount. The maximum aggregate principal amount of the Debentures which may be authenticated and delivered
under the Indenture and this Supplemental Indenture is $700,010,000 (except for Debentures authenticated and delivered upon registration of transfer of, or exchange for, or in lieu of, other Debentures pursuant to Section 3.4, 3.6, 3.7, 9.6 or
11.6 of the Indenture); provided, that, if the Underwriters exercise their option to purchase additional Trust Preferred Securities, the maximum aggregate principal amount of the Debentures which may be authenticated and delivered under the
Indenture and this Supplemental Indenture shall be $805,010,000 (except for Debentures authenticated and delivered upon registration of transfer of, or exchange for, or in lieu of, other Debentures pursuant to Section 3.4, 3.6, 3.7, 9.6 or 11.6
of the Indenture). 
  

 -9- 

 (c) Denominations. The Debentures will be issued only in fully registered form,
and the authorized minimum denomination of the Debentures shall be $25 principal amount and any integral multiple thereof. 
 (d) Maturity. The principal amount of the Debentures shall be payable in full on March 15, 2068 subject to and in accordance with the provisions of the Indenture and this Supplemental Indenture. 
 (e) Rate of Interest. The rate at which the Debentures shall bear interest will be 8.000% per annum; the date from which such
interest shall accrue is February 27, 2008; and the Interest Payment Dates on which such interest shall be payable are March 15, June 15, September 15 and December 15 of each year, commencing June 15, 2008.
Interest payments not paid when due will themselves accrue Additional Interest at the annual rate of 8.000% on the amount of unpaid interest, to the extent permitted by law, compounded quarterly. The amount of interest payable for any period will be
computed on the basis of a 360-day year comprised of twelve 30-day months. The amount of interest payable for any period shorter than a full quarterly period will be computed on the basis of a 30-day month and, for periods of less than a month, the
actual number of days elapsed per 30-day month. If an Interest Payment Date falls on a day that is not a Business Day, the interest payment shall be postponed to the next succeeding Business Day, without any interest or other payment in respect of
such delay. 
 (f) To Whom Interest Payable. Interest will be payable to the person in whose name the Debentures are
registered at the close of business on the Regular Record Date next preceding the Interest Payment Date, except that, interest payable on the Stated Maturity of the principal of the Debentures shall be paid to the Person to whom principal is paid.

 (g) Option to Defer Interest Payments. Section 3.12 of the Indenture shall not apply to the Debentures, which
shall be governed by the following provisions. 
 (i) The Company shall have the right, at any time and from time to time
prior to the Maturity of the Debentures, to defer the payment of interest thereon for one or more Optional Deferral Periods consisting of no more than 20 consecutive quarters, or five consecutive years, without becoming subject to the obligations
provided for in paragraph (h) of this Section 2.1. The Company shall also have the right, at any time and from time to time prior to the Maturity of the Debentures, to defer payment of interest thereon for one or more Optional Deferral
Periods consisting of no more than 40 consecutive quarters, or ten years, without giving rise to an Event of Default (after giving effect to paragraph (j) of this Section 2.1). During an Optional Deferral Period, any Deferred Interest on
the Debentures will accrue Additional Interest at an annual rate equal to 8.000%. No interest will be due and payable on the Debentures until the end of the Optional Deferral Period except upon a redemption of the Debentures during an Optional
Deferral Period or upon the payment of current interest (but only to the extent required by Section 2.1(g)). The Company may elect to so defer payment of interest by delivering to the Trustee written notice of such election at least ten 

  

 -10- 

 
Business Days and not more than 60 Business Days prior to the applicable Interest Payment Date. Notwithstanding the foregoing, no Optional Deferral Period
shall extend beyond the Maturity of the Debentures or, if earlier, the redemption or repayment in full of the Debentures. 
 (ii) (x) During any Optional Deferral Period, and, after a five-year Optional Deferral Period until the Company has paid all accrued and unpaid interest, or (y) at a time when (i) the Company has actual knowledge of an event that
with the giving of notice or the lapse of time, or both, would constitute a Debenture Default, (ii) the Company has not taken reasonable steps to cure the Debenture Default and (iii) the Debentures are held by the Trust and the Company is
in default with respect to its payment obligations under the Guarantee Agreement, the Company shall not, and shall not permit any Subsidiary of the Company to: 
 (A) declare or pay any dividends or distributions on or redeem, purchase, acquire or make a liquidation payment with respect to, any of
the Company’s capital stock, or make any guarantee payments relating to the foregoing, or 
 (B) make any payment of
principal of or interest or premium, if any, on or repay, purchase or redeem any Parity Securities or debt securities or guarantees of the Company that rank upon the Company’s liquidation junior to the Debentures, 
 other than (1) purchases, redemptions or other acquisitions of shares of capital stock of the Company in connection with (a) any employment
contract, benefit plan or other similar arrangement with or for the benefit of any one or more employees, officers, directors or consultants, (b) purchases pursuant to a contractually binding requirement to buy shares existing prior to the
commencement of the extension period, including pursuant to a contractually binding share repurchase plan, (c) transactions effected by or for the account of the customers of the Company or any Subsidiary or any affiliates of the Company or any
Subsidiary or in connection with the distribution, trading or market-making in respect of the Trust Preferred Securities, (d) a dividend reinvestment or shareholder stock purchase plan, or (e) the issuance of capital stock of the Company
(or securities convertible into or exercisable for such stock) as consideration in an acquisition transaction entered into prior to the Optional Deferral Period, (2) as a result of an exchange or conversion of any class or series of the
Company’s capital stock (or any capital stock of a Subsidiary of the Company) for any class or series of the Company’s capital stock or of any class or series of the Company’s indebtedness for any class or series of the Company’s
capital stock, (3) the purchase of fractional interests in shares of the Company’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged, (4) any declaration
of a dividend in connection with the implementation or amendment of any Company shareholders’ rights plan (or any successor thereto), or the issuance of rights, 

  

 -11- 

 
stock or other property under any such rights plan, or the redemption or repurchase of rights in accordance with any Company shareholders’ rights plan
(or any successor thereto) (5) any dividend in the form of stock, warrants, options or other rights where the dividend stock or the stock issuable upon exercise of such warrants, options or other rights is the same stock as that on which the
dividend is being paid or ranks pari passu with or junior to such stock, and (6) any payment of current or deferred interest on Parity Securities that is made pro rata to the amounts due on such Parity Securities (including the
Debentures) and any payments of principal or of deferred interest on Parity Securities that, if not made, would cause the Company to breach the terms of the instrument governing such Parity Securities. 
 (iii) Upon the payment of all Deferred Interest then due on the Debentures, the Company may elect to begin a new Optional Deferral Period,
which shall not extend beyond the Maturity or, if earlier, the redemption or repayment in full of the Debentures. After a Tenth Deferral Anniversary, the Company shall pay all Deferred Interest on the Debentures that has not been cancelled to the
extent permitted by applicable law, to the Persons in whose names the Debentures are registered at the close of business on the Regular Record Date with respect to the Interest Payment Date for such Tenth Deferral Anniversary. 
 (iv) In the case of any Optional Deferral Period that does not terminate on or prior to the first anniversary of the commencement of such
Optional Deferral Period, the restrictions set forth in Section 2.1(g)(ii) shall continue in effect in respect of any redemption, purchase or repurchase of the Company’s securities that rank pari passu with or junior in interest to
the Debentures upon the Company’s liquidation until the first anniversary of the termination of such Optional Deferral Period, unless any such redemption, purchase or repurchase is required by the FRB. 
 (v) The Company may pay current interest on any Interest Payment Date (including an Interest Payment Date that occurs after commencement
of an Optional Deferral Period) from any source of funds. Except as provided below in this subparagraph (v), the Company shall not pay Deferred Interest from any source of funds other than Eligible Equity Proceeds. Notwithstanding the foregoing
provisions of this Section 2.1(g) and the provisions of Section 2.1(h), if, during an Optional Deferral Period, a Supervisory Event has occurred and is continuing, the Company may choose to pay Deferred Interest using cash from any source,
but the Company is not obligated to do so and its election to do so will not constitute a breach of its obligation under Section 2.1(h) or any other provision of this Supplemental Indenture. 
 (h) Payment of Deferred Interest. 
 (i) Commencing on the earlier of (A) the Fifth Deferral Anniversary and (B) the date of any payment of current interest on the Debentures during an 

  

 -12- 

 
Optional Deferral Period, if any Deferred Interest is outstanding, the Company shall continuously use its Commercially Reasonable Efforts to effect sales of
Qualifying APM Securities in an amount that will generate sufficient net Eligible Equity Proceeds to enable the Company to pay in full all Deferred Interest on the Debentures then outstanding. Notwithstanding (and as a qualification to) the
foregoing or any other provision of this Supplemental Indenture, (x) the Company shall not be obligated to make offers for or effect sales of Qualifying APM Securities during the occurrence and continuation of a Market Disruption Event or a
Supervisory Event, (y) the Company will be permitted to pay Deferred Interest using cash from any source upon the occurrence of a Supervisory Event as provided for in paragraph (v) of Section 2.1(g) and (z) the Company shall not
pay interest on the Debentures at a time when such payment would violate a specific prohibition against payment of interest contained in the terms of any Parity Securities or securities ranking senior to the Debentures upon a liquidation of the
Company. The Company’s obligation to use Commercially Reasonable Efforts to sell Qualifying APM Securities to pay all Deferred Interest on the Debentures shall resume at such time as no Market Disruption Event or Supervisory Event exits or is
continuing. 
 (ii) The Company is not permitted to sell Common Stock, Qualified Warrants on Mandatorily Convertible Preferred
Stock such that the Common Stock to be issued (or which would be issuable upon exercise or conversion thereof) would be in excess of the “Maximum Share Number,” determined pursuant to this sub-paragraph (ii), for the purpose of satisfying
the Company’s obligations under Section 2.1(h)(i) or otherwise paying Deferred Interest on the Debentures then outstanding. The Maximum Share Number initially is 110 million shares. If the issued and outstanding shares of Common Stock
shall have been changed into a different number of shares or a different class by reason of any stock split, reverse stock split, stock dividend, reclassification, recapitalization, split-up, combination, exchange of shares or other similar
transaction, then the Maximum Share Number shall be correspondingly adjusted. The Company shall increase the Maximum Share Number (including through the increase of its authorized share capital, if necessary) to an amount that would allow the
Company to raise sufficient proceeds to satisfy its obligations to pay Deferred Interest in full at the end of the first year of an Optional Deferral Period (and on each subsequent anniversary of the end of the first year of an Optional Deferral
Period to the extent that an Optional Deferral Period would last more than one year), if the then-current Maximum Share Number would not allow the Company to raise sufficient proceeds to satisfy its obligations to pay Deferred Interest at such time
assuming a price per share equal to the average trading price of the Company’s common stock over the ten-trading-day period preceding such date; provided, however, that the Company will not be obligated to increase the Maximum
Share Number above 265 million shares. Until the Tenth Deferral Anniversary, a default will occur if the Company does not increase the Maximum Share Number to an amount that is greater than 110 million shares when required to do so as
described above, provided that no default will occur if the Company has increased the Maximum Share Number to 265 million shares. 
  

 -13- 

 (iii) Following the earlier of (A) the Fifth Deferral Anniversary and (B) the
date of any payment of current interest during an Optional Deferral Period, the Company shall apply the net proceeds received by it from sales of Qualifying APM Securities to the payment of all amounts owing in respect of Deferred Interest with net
proceeds to be paid promptly after receipt until all amounts owing in respect of Deferred Interest have been paid in full; provided, however, that the Company shall not be obligated to sell Qualifying APM Securities or apply the
proceeds of sales thereof to payment of Deferred Interest if a Market Disruption Event or a Supervisory Event has occurred and is continuing; provided, further, that if a Supervisory Event occurs because the FRB permits the Company to
sell Qualifying APM Securities but disapproves the application of the net proceeds of such sale to pay deferred interest, the Company may, if the FRB so directs, sell Qualifying APM Securities and apply the proceeds to a purpose other than paying
Deferred Interest without creating a breach of its obligations under this Section 2.1(h) or any other provision of this Supplemental Indenture. In the event that net proceeds received by the Company from one or more sales of Qualifying APM
Securities following the earlier of (x) such Fifth Deferral Anniversary and (y) the date of any payment of current interest during an Optional Deferral Period are not sufficient to satisfy the full amount of Deferred Interest, such net
proceeds will be paid to the holders of the Debentures on a pro rata basis; provided, however, that, if the Company has outstanding at such time any Parity Securities under the terms of which the Company is obligated (I) to
sell Qualifying APM Securities and apply the net proceeds to payment of deferred interest (including additional interest thereon) or (II) to apply the proceeds of any Qualifying APM Securities to payment of deferred interest (including additional
interest thereon), then on any date and for any period the amount of net proceeds received by the Company from such sales of Qualifying APM Securities and available for payment of Deferred Interest shall be applied to the Debentures and such Parity
Securities on a pro rata basis, taking into account any net proceeds from the sales of securities other than Qualifying APM Securities that would be permitted to be applied to the payment of deferred interest (including additional interest
thereon) on any such Parity Securities but not on the Debentures. Notwithstanding the above, the Company shall not be obligated to sell Qualifying APM Securities or to apply such net proceeds or any portion thereof to the payment of Deferred
Interest during the occurrence and continuation of Market Disruption Event or a Supervisory Event. 
 (iv) If on any date or
for any period the Company pays interest on any class of Parity Securities in an amount that is less than the full amount of accrued but unpaid interest, the Company shall make payments on all outstanding classes of Parity Securities on the same
date or for the corresponding period on a pro rata basis (based on the total amount then due), except and to the extent the terms of such Parity Securities will prohibit the Company from doing so, or except to the extent such payment is made
pursuant to Section 2.1(g)(ii) and that, if not made, would cause the Company to breach the terms of the instrument governing such Parity Securities. 
  

 -14- 

 (v) Notwithstanding anything to contrary in this Supplemental Indenture, the Company will
not be obligated to issue Qualifying APM Securities that are of Common Stock (or Qualified Warrants if the definition of Qualifying APM Securities has been modified to exclude Common Stock) prior to the Fifth Deferral Anniversary if the gross
proceeds of any issuance of Common Stock (or Qualified Warrants if the definition of Qualifying APM Securities has been modified to exclude Common Stock) applied during such Deferral Period to pay Deferred Interest, together with the gross proceeds
of all prior issuances of Common Stock and Qualified Warrants so applied during such Deferral Period, would exceed an amount equal to 2% of the product of (1) the average of the Current Stock Market Prices of the Common Stock on the 10
consecutive trading days ending on the fourth trading day immediately preceding the date of issuance and (2) the total number of issued and outstanding shares of Common Stock as of the date of the Company’s then most recent publicly
available consolidated financial statements (the “Common Equity Issuance Cap”). Once the Company reaches the Common Equity Issuance Cap for an Optional Deferral Period, the Company will not be obligated to issue more Eligible Equity
pursuant to this Section 2.1(h) prior to the Fifth Deferral Anniversary even if the Current Stock Market Price of the Company’s Common Stock or the number of outstanding shares of its Common Stock subsequently increase. The Common Equity
Issuance Cap will cease to apply following the Fifth Deferral Anniversary, at which point the Company must repay any Deferred Interest, regardless of the time at which it was deferred, using proceeds from sales of Qualifying APM Securities that are
Common Stock or Qualified Warrants, subject to any Market Disruption Event, Supervisory Event, and the Maximum Share Number. If the Common Equity Issuance Cap has been reached during an Optional Deferral Period and the Company subsequently repays
all Deferred Interest, the Common Equity Issuance Cap will cease to apply at the termination of such Optional Deferral Period and will not apply again unless and until the Company starts a new Optional Deferral Period. 
 (vi) Notwithstanding anything to contrary in this Supplemental Indenture, the Company will not be obligated to issue Qualifying APM
Securities that are Qualifying Preferred Stock and Mandatorily Convertible Preferred Stock to settle Deferred Interest to the extent that the net proceeds of any issuance of Qualifying Preferred Stock applied to pay interest on the Debentures
pursuant to the Alternative Payment Mechanism, together with the net proceeds of all prior issuances of Qualifying Preferred Stock and Mandatorily Convertible Preferred Stock so applied during the current and all prior Deferral Periods, would exceed
25% of the aggregate principal amount of the outstanding Debentures (the “Preferred Stock Issuance Cap”). 
 (vii) If the Company engages in any transaction that is subject to Section 8.1 of the Indenture, where immediately after the consummation of such transaction more than 50% of the voting stock of the Person formed by such transaction,
or the Person that is the surviving entity of such transaction, or the Person to whom such properties and assets are conveyed, transferred or leased in 

  

 -15- 

 
such transaction, is owned by the shareholders of the other party to such transaction, then the restrictions of this Section 2.1(h) shall not apply to
any interest on the Debentures that is deferred and unpaid as of the date of consummation of such transaction and, with respect to any Deferral Period that is terminated on the next Interest Payment Date following the date of consummation of such
transaction, Section 2.1(g)(iv) shall not apply. 
 (i) Notices. 
 (i) If during an Optional Deferral Period a Market Disruption Event has occurred and is continuing, the Company shall give, as promptly as
possible after the Company becomes aware of such occurrence, a written notice to the Trustee, stating the date on which such Market Disruption Event has occurred, the nature thereof and what action it will take in connection therewith. 

(ii) If during an Optional Deferral Period a Supervisory Event has occurred and is continuing, the Company shall give, as promptly as
possible after the Company becomes aware of such occurrence, a written notice to the Trustee stating that a Supervisory Event has commenced and the actions it will take in connection therewith. 
 (iii) The Company shall give written notice to the FRB (A) no later than 5 Business Days following commencement of an Optional
Deferral Period and (B) upon the earlier to occur of (1) the Fifth Deferral Anniversary of such Optional Deferral Period or (2) the payment of current interest during an Optional Deferral Period. 
 (iv) At least 25 Business Days in advance of the relevant payment date (or such longer period as may be required by the FRB or by other
supervisory action) the Company shall give written notice to the FRB of its intent both (A) to sell Eligible Equity and (B) to apply the net proceeds from such sale to pay Deferred Interest, and shall only take any such actions if the FRB
does not disapprove of any such actions within 10 Business Days (or such longer period as may be required by FRB order or by other supervisory action) after the Company gives such notice to the FRB or has withdrawn any prior disapproval. 

(v) The Company shall give written notice to the Holders of the Debentures and the Trust shall give written notice to the holders of
the Trust Preferred Securities prior to the effective date of any change in the definition of Qualifying APM Securities pursuant to Section 3.6 hereof. 
 (j) Events of Default. For the Debentures, Sections 5.1 and 5.2 of the Indenture shall not apply and shall be replaced with Annex A
attached hereto. 
 (k) Location of Payment. Payment of the principal of (and premium, if any) and interest on the
Debentures will be made at the corporate trust office of the Trustee, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that
at the option of 

  

 -16- 

 
the Company payment of interest may be made (i) by check mailed to the address of the Person entitled thereto as such address shall appear in the
Securities Register or (ii) by wire transfer in immediately available funds at such place and to such account as may be designated by the Person entitled thereto as specified in the Securities Register; provided, further, that,
for so long as the Trust appears on the Securities Register as a Holder of Debentures and in a timely manner has provided wire transfer instructions to the Company with respect to payments on the Debentures, all payments to the Trust as Holder of
Debentures shall be made by wire transfer in immediately available funds to the account specified in such wire transfer instructions. The office where the Debentures may be presented or surrendered for payment and the office where the Debentures may
be surrendered for transfer or exchange and where notices and demands to or upon the Company in respect of the Debentures and the Indenture may be served shall be the Corporate Trust Office. The Trustee shall act as Paying Agent. 
 (l) Redemption. 
 (i) The Debentures are redeemable at the option of the Company, subject to the terms and conditions of Article XI of the Indenture and subject to the Company having received prior approval from the FRB if then
required under applicable capital guidelines or policies of the FRB, (i) in whole or in part, at 100% of their principal amount plus accrued and unpaid interest, on one or more occasions at any time on or after March 15, 2013, (ii) in
whole, at 100% of their principal amount plus accrued and unpaid interest, at any time if a Special Event other than a Rating Agency Event has occurred and is continuing and the Company cannot cure the Special Event by some reasonable action, in
which case the Company may redeem the Debentures within 90 days following the occurrence of the Special Event, or (iii) in whole, at the Make-whole Redemption Price, plus accrued and unpaid interest, at any time if a Rating Agency Event has
occurred and is continuing and the Company cannot cure the Rating Agency Event by some reasonable action, in which case the Company may redeem the Debentures within 90 days following the occurrence of the Rating Agency Event. 
 (ii) Notice of any redemption and, in the case of any redemption upon the occurrence and continuation of a Rating Agency Event, the amount
of the Make-whole Redemption Price, will be given at least 30 days but not more than 60 days before the redemption date to each holder of junior subordinated debentures at its registered address. 
 (m) Limitation on Claims in the Event of Bankruptcy, Insolvency or Receivership. Notwithstanding anything to the contrary in the
Indenture or this Supplemental Indenture, each Holder of a Debenture, by such Holder’s acceptance thereof, agrees that upon any payment or distribution of assets to creditors of the Company upon any liquidation, dissolution, winding up,
reorganization, or in connection with any insolvency, receivership or proceeding under any bankruptcy law with respect to the Company, such Holder shall have no claim for accrued and unpaid interest (including compounded interest thereon) that has
not been settled through the application of the Alternative Payment Mechanism to the extent that the aggregate amount thereof 

  

 -17- 

 
exceeds the amount of the first two years of accumulated and unpaid Deferred Interest for any Optional Deferral Period. 
 (n) Sinking Fund. The Debentures shall not be subject to any sinking fund or analogous provisions. 
 (o) Forms. The Debentures shall be substantially in the form of Annex B attached hereto, with such modifications thereto as may be
approved by the authorized officer executing the same. The Trust Agreement shall be substantially in the form of Annex D attached hereto, with such modifications thereto as may be approved by the authorized officer executing the same. The Guarantee
Agreement shall be substantially in the form of Annex C attached hereto, with such modifications thereto as may be approved by the authorized officer executing the same. 
 (p) Subordination. The subordination provisions of Article XIII of the Indenture shall apply; provided, however, that
for the purposes of the Debentures (but not for the purposes of any other Securities unless specifically set forth in the terms of such Securities), the definitions of “Senior Debt” and “Senior Indebtedness” in the Indenture are
hereby amended in their entirety to read as follows: 
 “‘Allocable Amounts,’ when used with respect to any Senior
Subordinated Debt or Junior Subordinated Debt, means the amount necessary to pay all principal (and premium, if any) and interest, if any, on such Senior Subordinated Debt or Junior Subordinated Debt, as applicable, in full less, if applicable, any
portion of such amount which would have been paid to, and retained by, the holders of such Senior Subordinated Debt or Junior Subordinated Debt, as applicable (whether as a result of the receipt of payments by the holders of such Senior Subordinated
Debt or Junior Subordinated Debt, as applicable, or any other obligor thereon or from any holders of, or trustee in respect of, other indebtedness that is subordinate and junior in right of payment to such Senior Subordinated Debt or Junior
Subordinated Debt, as applicable, pursuant to any provision of such indebtedness for the payment over of amounts received on account of such indebtedness to the holders of such Senior Subordinated Debt or Junior Subordinated Debt, as applicable) but
for the fact that such Senior Subordinated Debt or Junior Subordinated Debt, as applicable, is subordinate or junior in right of payment to trade accounts payable or accrued liabilities arising in the ordinary course of business.” 

“‘Senior Debt’ means any obligation of the Company to its creditors, whether now outstanding or subsequently incurred, other than
any obligation as to which, in the instrument creating or evidencing the obligation or pursuant to which the obligation is outstanding, it is provided that such obligation is not Senior Debt; provided, however, that Senior Debt does
not include Senior Subordinated Debt, Junior Subordinated Debt or Pari Passu Securities.” 
  

 -18- 

 “‘Senior Indebtedness’ means (i) Senior Debt (but excluding trade accounts
payable and accrued liabilities arising in the ordinary course of business), (ii) the Allocable Amounts of Senior Subordinated Debt, and (iii) the Allocable Amounts of Junior Subordinated Debt.” 
 Additionally, 
 “Pari Passu Securities”
means (i) indebtedness (A) the terms of which provide that such indebtedness ranks equally with the Debentures, the Company’s 7% Junior Subordinated Debentures due June 15, 2066, and the Company’s 6.750% Junior Subordinated
Debentures due 2066 upon the Company’s liquidation and (B) that qualifies or is issued to financing vehicles issuing securities that qualify as Tier 1 capital of the Company at the time of issuance under the capital guidelines of the FRB;
and (ii) guarantees of indebtedness described in clause (i) or securities issued by one or more financing vehicles described in clause (i)(B).

date on which written notice of such failure, requiring the Company to remedy the same, shall have been given to the Company by the Trustee by registered or certified mail or to the Company and the Trustee by the Holders of at least 25% in aggregate
principal amount of the Outstanding Debentures. 
 Section 5.2. Acceleration of Maturity; Rescission and Annulment. 
 If an Event of Default described in clause (1) of Section 5.1(a) with respect to the Debentures occurs and is continuing, then and in every such
case the Trustee or the Holders of not less than 25% in aggregate principal amount of the Outstanding Debentures may declare the principal amount of all the Debentures to be due and payable immediately, by a notice in writing to the Company (and to
the Trustee if given by Holders), provided that, for so long as the Trust is the holder of all of the Outstanding Debentures, if, upon such an Event of Default, the Trustee or the holders of at least 25% of the outstanding principal amount of
the Debentures fails to declare the principal of all the Outstanding Debentures to be immediately due and payable, the holders of at least 25% in aggregate Liquidation Amount (as defined in the Trust Agreement) of the Trust Preferred Securities then
outstanding shall have the right to make such declaration by a notice in writing to the Company and the Trustee; and upon any such declaration such principal amount (or specified portion thereof) of and the accrued interest (including any Additional
Interest) on all the Debentures shall become immediately due and payable. Payment of principal and interest (including any Additional Interest) on the Debentures shall remain subordinated to the extent provided in the Indenture (as supplemented by

money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in aggregate principal amount of the Outstanding Debentures, by written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if:

 (2) all Events of Default with respect to the Debentures, other than the non-payment of the principal of the Debentures that has become
due solely by such acceleration, have been cured or waived as provided in Section 5.13.

 CUSIP No. 
 KEYCORP, a corporation organized and existing under the laws of the State of Ohio (hereinafter called the “Company,” which term includes any
successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay Deutsche Bank Trust Company Americas, as Property Trustee of KEYCORP CAPITAL X, or registered assigns, the principal sum of
                     dollars
($                    ) on March 15, 2068. The Company further promises to pay interest on said principal sum from February 27, 2008 or
from the most recent interest payment date (each such date, an “Interest Payment Date”) on which interest has been paid or duly provided for, quarterly (subject to deferral as set forth herein) in arrears on
March 15, June 15, September 15 and December 15 of each year, commencing June 15, 2008, at the rate of 8.000% per annum, until the principal hereof shall have become due and payable, and on any overdue
principal and (without duplication and to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the same rate per annum, compounded quarterly. The amount of interest payable for any
period will be computed on the basis of a 360-day year comprised of twelve 30-day months. The amount of interest payable for any period shorter than a full quarterly period will be computed on the basis of a 30-day month period and, for periods of
less than a month, the actual number of days elapsed per 30-day month. In the event that any date on which interest is payable on this Security is not a Business Day, then a payment of the interest payable on such date will be made on the next
succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay). A “Business Day” shall mean any day other than (i) a Saturday or Sunday, (ii) a day on which banking institutions in
The City of New York are authorized or required by law or executive order to remain closed or (iii) a day on which the Corporate Trust Office of the Property Trustee or the principal offices of the Property Trustee under the Trust Agreement
hereinafter referred to for KEYCORP CAPITAL X, is closed for business. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose
name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest installment, which shall be (i) the Business Day next 
  

	1	This form assumes that KeyCorp Capital X is the sole holder of record of the Debentures. If Debentures are held by any other Person, pursuant to Section 2.1 of the Base
Indenture, the Company shall establish by Board Resolution a revised form of Debenture. 

  

 B-1 

 preceding such Interest Payment Date if this Security is issued in
the form of a Global Security, or (ii) the fifteenth (15) day (whether or not a Business Day) preceding such Interest Payment Date if this Security is not issued in the form of a Global Security. Any such interest installment not so
punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than ten (10) days prior to such Special Record Date, or be
paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more full provided
in said Indenture. 
 The Company shall have the right, at any time and from time to time during the term of this Security, to defer the
payment of interest thereon for one or more Optional Deferral Periods consisting of no more than 20 consecutive quarters, or five consecutive years, without becoming subject to the obligations to issue Common Stock and pay Deferred Interest pursuant
to Section 2.1(h) of the Fifth Supplemental Indenture. The Company shall also have the right, at any time and from time to time during the term of this Security, to defer payment of interest thereon for one or more Optional Deferral Periods
consisting of no more than 40 consecutive quarters, or ten consecutive years, without giving rise to an Event of Default. The Company may elect to so defer payment of interest by delivering to the Trustee written notice of such election at least ten
and not more than 60 Business Days prior to the applicable Interest Payment Date. Notwithstanding the foregoing, no Optional Deferral Period shall extend beyond the Stated Maturity of the principal of this Security. 
 (x) During any Optional Deferral Period, and, after a five-year Optional Deferral Period until the Company has paid all accrued and unpaid interest, or
(y) at a time when (i) the Company has actual knowledge of an event that with the giving of notice or the lapse of time, or both, would constitute a Debenture Default, (ii) the Company has not taken reasonable steps to cure the
Debenture Default and (iii) the Debentures are held by the Trust and the Company is in default with respect to its payment obligations under the Guarantee Agreement, the Company shall not, and shall not permit any Subsidiary of the Company to:

 (a) declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a liquidation payment with
respect to, any of the Company’s capital stock, or make any guarantee payments relating to the foregoing, or 
 (b) make
any payment of principal of or interest or premium, if any, on or repay, purchase or redeem any Parity Securities or debt securities or guarantees of the Company that rank upon the Company’s liquidation junior to the Debentures, 
 other than (1) purchases, redemptions or other acquisitions of shares of capital stock of the Company in connection with (a) any employment contract, benefit
plan or other similar arrangement with or for the benefit of any one or more employees, officers, directors or consultants, (b) purchases pursuant to a contractually binding requirement to buy shares existing prior to the commencement of the
extension period, including pursuant to a contractually binding 

  

 B-2 

 
share repurchase plan, (c) transactions effected by or for the account of the customers of the Company or any Subsidiary or any affiliates the Company
or any Subsidiary or in connection with the distribution, trading or market-making in respect of the Trust Preferred Securities, (d) a dividend reinvestment or shareholder stock purchase plan, or (e) the issuance of capital stock of the
Company (or securities convertible into or exercisable for such stock) as consideration in an acquisition transaction entered into prior to the Optional Deferral Period, (2) as a result of an exchange or conversion of any class or series of the
Company’s capital stock (or any capital stock of a Subsidiary of the Company) for any class or series of the Company’s capital stock or of any class or series of the Company’s indebtedness for any class or series of the Company’s
capital stock, (3) the purchase of fractional interests in shares of the Company’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged, (4) any declaration
of a dividend in connection with the implementation or amendment of any Company shareholders’ rights plan (or any successor thereto), or the issuance of rights, stock or other property under any such rights plan, or the redemption or repurchase
of rights in accordance with any Company shareholders’ rights plan (or any successor thereto), (5) any dividend in the form of stock, warrants, options or other rights where the dividend stock or the stock issuable upon exercise of such
warrants, options or other rights is the same stock as that on which the dividend is being paid or ranks pari passu with or junior to such stock, and (6) any payments of current or deferred interest on Parity Securities that is made
pro rata to the amounts due on such Parity Securities (including the Debentures) and any payments of principal or of deferred interest on Parity Securities that, if not made, would cause the Company to breach the terms of the instrument
governing such Parity Securities. 
 Payment of principal of (and premium, if any) and interest on this Security will be made at the office
or agency of the Company maintained for that purpose in the United States, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at
the option of the Company payment of interest may be made (i) by check mailed to the address of the Person entitled thereto as such address shall appear in the Securities Register or (ii) by wire transfer in immediately available funds at
such place and to such account as may be designated in writing at least fifteen (15) days before the relevant Interest Payment Date by the Person entitled thereto as specified in the Securities Register; provided, further, that
for so long as KeyCorp Capital X appears on the Securities Register as a Holder of Debentures and in a timely manner has provided wire transfer instructions to the Company with respect to payments on the Debentures, all payments to KeyCorp Capital X
as Holder of the Debentures shall be made by wire transfer in immediately available funds to the account specified in such wire transfer instructions. 
 The indebtedness evidenced by this Security is, to the extent provided in the Indenture, subordinated and subject in right of payments to the prior payment in full of all Senior Debt (as such definition is modified in
the Fifth Supplemental Indenture with respect to this Security), and this Security is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound
by such provisions, (b) authorizes and directs the Trustee on his behalf to take such actions as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee his attorney-in-fact for any and all
such purposes. Each Holder hereof, by his acceptance hereof, waives all notice of the acceptance of the subordination provisions contained herein and 

  

 B-3 

 
in the Indenture by each holder of Senior Debt, whether now outstanding or hereafter incurred, and waives reliance by each such holder upon said provisions.

 Reference is made hereby to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

 REVERSE OF SECURITY 
 This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under a Junior Subordinated Indenture, dated as of
December 4, 1996, as supplemented by the First Supplemental Indenture, dated as of June 13, 2005, a Second Supplemental Indenture, dated as of August 1, 2005, a Third Supplemental Indenture, dated as of June 20, 2006, a Fourth
Supplemental Indenture, dated as of November 21, 2006, and a Fifth Supplemental Indenture, dated as of February 27, 2008 (the “Fifth Supplemental Indenture” and, together with the Supplemental Indentures referenced above, herein
called the “Indenture”), between the Company and Deutsche Bank Trust Company Americas, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities, and of the terms upon which the Securities
are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to $805,010,000 issuable on one or more occasions. 
 All terms used in this Security that are defined in the Indenture or in the Amended and Restated Trust Agreement, dated as of February 27, 2008 (the
“Trust Agreement”), for KEYCORP CAPITAL X, among KeyCorp, as Sponsor, and the Trustees named therein, shall have the meanings assigned to them in the Indenture or the Trust Agreement, as the case may be. 
 The Company may at any time, at its option, on or after March 15, 2013, and subject to the terms and conditions of Article XI of the Indenture and
Section 2.1(l) of the Fifth Supplemental Indenture, and subject to prior approval by the Board of Governors of the Federal Reserve System if then required, redeem this Security in whole at any time or in part from time to time, without premium
or penalty, at a redemption price equal to 100% of the principal amount thereof plus accrued and unpaid interest, including Additional Interest, if any, to the Redemption Date. 
 Upon the occurrence and during the continuation of a Tax Event, Investment Company Event or a Regulatory Capital Event in respect of the Trust, the
Company may, at its option, at any time within 90 days of the occurrence of such Tax Event, Investment Company Event or Regulatory Capital Event redeem this Security, in whole but not in part, subject to the provisions of Article XI of the
Indenture, at a redemption price equal to 100% of the principal amount thereof plus accrued and unpaid interest, including Additional Interest, if any, to the Redemption Date. 
 Upon the occurrence and during the continuation of a Rating Agency Event, the Company may, at its option, at any time within 90 days of the occurrence of
such Rating Agency Event redeem this Security, in whole but not in part, subject to the provisions of Article XI of the Indenture, at a redemption price equal to the Make-whole Redemption Price plus accrued and unpaid interest, including Additional
Interest, if any, to the Redemption Date. 
 Commencing on the earlier of (A) the Fifth Deferral Anniversary and (B) the date of
any payment of current interest on the Debentures during an Optional Deferral Period, if any 

  

 B-6 

 
Deferred Interest is outstanding, the Company shall continuously use its Commercially Reasonable Efforts to effect sales of Qualifying APM Securities in an
amount that will generate sufficient net Eligible Equity Proceeds to enable the Company to pay in full all Deferred Interest on the Debentures then outstanding. Notwithstanding (and as a qualification to) the foregoing or any other provision of this
Supplemental Indenture, (x) the Company shall not be obligated to make offers for or effect sales of Qualifying APM Securities during the occurrence and continuation of a Market Disruption Event or a Supervisory Event, (y) the Company will
be permitted to pay Deferred Interest using cash from any source upon the occurrence of a Supervisory Event as provided for in paragraph (v) of Section 2.1(g) of the Fifth Supplemental Indenture and (z) the Company shall not pay
interest on the Debentures at a time when such payment would violate a specific prohibition against payment of interest contained in the terms of any Parity Securities or securities ranking senior to the Debentures upon a liquidation of the Company.
The Company’s obligation to use Commercially Reasonable Efforts to sell Common Stock to pay all Deferred Interest on the Debentures shall resume at such time as no Market Disruption Event or Supervisory Event exits or is continuing. 

Following the earlier of (A) the Fifth Deferral Anniversary and (B) the date of any payment of current interest during an Optional Deferral
Period, the Company shall apply the net proceeds received by it from sales of Qualifying APM Securities to the payment of all amounts owing in respect of Deferred Interest with net proceeds to be paid promptly after receipt until all amounts owing
in respect of Deferred Interest have been paid in full; provided, however, that the Company shall not be obligated to sell Qualifying APM Securities or apply the proceeds of sales thereof to payment of Deferred Interest if a Market Disruption
Event or a Supervisory Event has occurred and is continuing; provided, further, that if a Supervisory Event occurs because the FRB permits the Company to sell Qualifying APM Securities but disapproves the application of the net proceeds of such sale
to pay deferred interest, the Company may, if the FRB so directs, sell Qualifying APM Securities and apply the proceeds to a purpose other than paying Deferred Interest without creating a breach of its obligations under Section 2.1(h) or any
other provision of the Fifth Supplemental Indenture. In the event that net proceeds received by the Company from one or more sales of Qualifying APM Securities following the earlier of (x) such Fifth Deferral Anniversary and (y) the date
of any payment of current interest during an Optional Deferral Period are not sufficient to satisfy the full amount of Deferred Interest, such net proceeds will be paid to the holders of the Debentures on a pro rata basis; provided,
however, that, if the Company has outstanding at such time any Parity Securities under the terms of which the Company is obligated (I) to sell Qualifying APM Securities and apply the net proceeds to payment of deferred interest (including
additional interest thereon) or (II) to apply the proceeds of any Qualifying APM Securities to payment of deferred interest (including additional interest thereon), then on any date and for any period the amount of net proceeds received by the
Company from such sales of Qualifying APM Securities and available for payment of Deferred Interest shall be applied to the Debentures and such Parity Securities on a pro rata basis, taking into account any net proceeds from the sales of
securities other than Qualifying APM Securities that would be permitted to be applied to the payment of deferred interest (including additional interest thereon) on any such Parity Securities but not on the Debentures. Notwithstanding the above, the
Company shall not be obligated to sell Qualifying APM Securities or to apply such net proceeds or any portion thereof to the payment of Deferred Interest during the occurrence and continuation of Market Disruption Event or a Supervisory Event.

  

 B-7 

 The foregoing is part of the Alternative Payment Mechanism set forth in the Fifth Supplemental Indenture
and is subject to the qualifications, limitations and other provisions set forth in the Fifth Supplemental Indenture. 
 The Indenture
contains provisions for satisfaction and discharge of the entire indebtedness of this Security upon compliance by the Company of certain conditions set forth in the Indenture. 
 The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee at any time to enter into a supplemental indenture or
indentures for the purpose of modifying in any manner the rights and obligations of the Company and of the Holders of the Securities, with the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities of
all series to be affected by such supplemental indenture. The Indenture also contains provisions permitting Holders of specified percentages in principal amount of the Securities of all 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 Holders of this Security and of any
Security issued upon the registration and transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 
 As provided in and subject to the provisions of the Indenture, if an Event of Default with respect to the Securities of this series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee or the Holders of not less that 25% in principal amount of the Outstanding Securities of this series may declare the principal amount of all the Securities of this series
to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), provided that, in the case of the Securities of this series issued to a Trust, if upon an Event of Default, the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding Securities of this series fails to declare the principal of all the Securities of this series to be immediately due and payable, the holders of at least 25% in aggregate
Liquidation Amount of the Trust Preferred Securities then outstanding shall have such right by a notice in writing to the Company and the Trustee; and upon any such declaration the principal amount of and the accrued interest (including Additional
Interest) on all the Securities of this series shall become immediately due and payable, provided that the payment of principal and interest (including Additional Interest) on such Securities shall remain subordinated to the extent provided
in Article XIII of the Indenture and Section 2.1(p) of the Fifth Supplemental Indenture. 
 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 premium, if any) and interest on this Security at the times, places and rate, and
in the coin or currency, herein prescribed (subject to the deferral rights of the Company described in the Indenture). 
 As provided in the
Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Securities Register, upon surrender of this Security for registration of transfer at the office or agency of the Company maintained
under 

  

 B-8 

 
Section 10.2 of the Indenture duly endorsed by, or accompanied by written instrument of transfer in form satisfactory to the Company and the Securities
Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection
therewith. 
 Prior to due presentment of this Security for registration or transfer, the Company, the Trustee and any agent of the Company
or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary. 
 The Securities of this series are issuable only in registered form without coupons in denominations of $25 and in any multiple
thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for like aggregate principal amount of Securities of such series of a different authorized denomination, as
requested by the Holder surrendering the same. 
 The Company and, by its acceptance of this Security or a beneficial interest therein, the
Holder of, and any Person that acquires beneficial interest in, this Security agree that for United States federal, state and local tax purposes it is intended that this Security constitute indebtedness. 
 THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
