5

amendment, clarification, change, interpretation, pronouncement or administrative action is effective and applicable) that the Bank is, or may be, subject to more than a de minimis amount of additional taxes, duties or other governmental charges or civil liabilities because the treatment of any of its items of income, taxable income, expense, taxable capital or taxable paid-up capital with respect to the Notes or the treatment of the Notes, as or as would be reflected in any tax return or form filed, to be filed, or otherwise could have been filed, will not be respected by a taxing authority; provided that this clause (iii) shall not apply in respect of the deductibility of interest on the Notes.

“Treasury Yield” means, for any Subsequent Fixed Rate Period, (i) the rate per annum corresponding to the semi-annual equivalent yield to maturity, that represents the average for the week that ends immediately before the week in which the applicable Reset Interest Determination Date falls, appearing in the most recently published statistical release designated “H.15” or any successor publication that is published by the Board of Governors of the United States Federal Reserve System and that establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities”, for the 5-Year U.S. Treasury Bond as that rate is displayed on the Reuters screen FEDCMT page or (ii) if there is no such published U.S. Treasury security with a maturity of five-years from the next Reset Date and trading in the public securities markets, then the rate will be determined by the Calculation Agent by interpolation between the most recent weekly average yield to maturity for two series of U.S. Treasury securities trading in the public securities market, (A) one maturing as close as possible to, but earlier than, the Reset Date following the next succeeding Reset Interest Determination Date, and (B) the other maturity as close as possible to, but later than, the Reset Date following the next succeeding Reset Interest Determination Date, in each case as published in the most recent H.15. If the Treasury Yield cannot be determined pursuant to the methods described in clauses (i) or (ii) above, then the Treasury Yield will be the same interest rate determined for the prior Reset Interest Determination Date.

“Trigger Event” has the meaning set out in the OSFI, Guideline for Capital Adequacy Requirements (CAR), Chapter 2 — Definition of Capital, effective April 2018, as such term may be amended or superseded by OSFI from time to time, which term currently provides that each of the following constitutes a Trigger Event:

6

or appropriate, it is reasonably likely that the viability of the Bank will be restored or maintained; or

Section 104.    Conflict with Base Indenture.

If any provision of this Third Supplemental Indenture relating to the Notes is inconsistent with any provision of the Base Indenture, such provision of this Third Supplemental Indenture shall control.

Section 105.    Provisions of Trust Indenture Act.

If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under the Trust Indenture Act to be a part of and govern this Third Supplemental Indenture, the latter provision shall control. If any provision of this Third Supplemental Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to apply to this Third Supplemental Indenture as so modified or to be excluded, as the case may be.

Section 106.    Separability Clause.

The Notes shall be issued initially in the form of one or more fully registered global notes (each such global note, a “Global Note”) deposited with DTC or its designated custodian or such other Depositary as any officer of the Bank may from time to time designate. 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 Bank or to a nominee of such successor Depositary.

Section 205.    Interest.

(a)    From and including the Issue Date to, but excluding, the First Reset Date, interest shall accrue on the Notes at an initial rate equal to 4.800% per annum. Thereafter, for each period commencing on a Reset Date, from and including such Reset Date to, but excluding the following Reset Date (each, a “Subsequent Fixed Rate Period”), interest shall accrue on the Notes at a rate per annum equal to the applicable Treasury Yield plus 2.979%, as determined by the Calculation Agent on the applicable Reset Interest Determination Date. The Bank shall, following each Reset Date, promptly notify the Trustee in writing of the interest rate payable on the Notes from and including such Reset Date.

(b)    Subject to the Bank’s right to cancel interest payments pursuant to Section 206(a) of this Third Supplemental Indenture, interest on the Notes shall be payable semi-annually in arrears on February 25 and August 25 of each year (each, an “Interest Payment Date”), commencing February 25, 2020. If any Interest Payment Date falls on a day that is not a Business Day for the Notes, the Bank shall postpone the making of such interest payment to the next succeeding Business Day (and no interest shall be paid in respect of the delay).

(c)    Interest on the Notes shall be calculated and paid on the basis of a 360-day year of twelve 30-day months.

(d)    Notwithstanding any provision in the Indenture or the Notes, the interest rate on the Notes shall in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application and in no event shall the interest rate on the Notes be less than zero.

(e)    All determinations and calculations of the Calculation Agent, in the absence of manifest error, shall be conclusive and binding on the Bank and the Holders of the Notes.

(a) Notwithstanding any provision in the Base Indenture or this Third Supplemental Indenture, (i) interest on the Notes shall be due and payable on an Interest Payment Date only if it is not cancelled by the Bank, and (ii) the Bank shall have the sole and absolute discretion at all times and for any reason to cancel (in whole or in part) any interest payment that would otherwise be payable on any Interest Payment Date and any interest cancelled pursuant to this Section 206(a) shall not accumulate or be due and payable at any time thereafter and the Holders

9

and beneficial owners of the Notes shall have no rights thereto or to receive any additional interest or compensation as a result of such cancellation of interest in respect of the Notes.

(b)    Upon any election by the Bank to cancel (in whole or in part) any interest payment pursuant to Section 206(a) of this Third Supplemental Indenture, the Bank shall give notice to the Holders of the Notes through DTC (or, if the Notes are held in definitive form, to the Holders directly at their addresses shown in the Security Register) and to the Trustee on or prior to the relevant Interest Payment Date, specifying the amount of the relevant interest cancellation and, accordingly, the amount (if any) of the interest that will be paid on such Interest Payment Date. Failure to provide such notice shall not have any impact on the effectiveness of, or otherwise invalidate, any such cancellation of interest, or give the Holders or beneficial owners of the Notes any rights as a result of such failure.

(c)    Any interest on the Notes which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date and which has not been cancelled pursuant to Section 206(a) of this Third Supplemental Indenture (such interest herein called “Nonpayment Interest”) shall be paid by the Bank on the next succeeding Interest Payment Date to the Holders of the Notes on the Regular Record Date, immediately preceding such Interest Payment Date; provided that no additional interest or compensation shall accrue on the Nonpayment Interest or be payable as a result of such delay in payment.

Section 207.    Satisfaction and Discharge.

The provisions of Article Four of the Base Indenture shall not be applicable to the Notes; however, the following shall apply to the Notes:

The Indenture shall upon Bank Request cease to be of further effect, and the Trustee, at the expense of the Bank, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when (a) all Notes theretofore authenticated and delivered (other than (i) Notes which have been mutilated, destroyed, lost or stolen and which have been replaced or paid as provided in Section 306 of the Base Indenture and (ii) Notes for whose payment money has theretofore been irrevocably deposited in trust or segregated and held in trust by the Bank and thereafter repaid to the Bank or discharged from such trust, as provided in Section 1003 of the Base Indenture) have been delivered to a Trustee for cancellation; (b) the Bank has paid or caused to be paid all other sums payable hereunder by the Bank; and (c) the Bank has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel stating that all conditions precedent herein provided for relating to the satisfaction and discharge of the Indenture have been complied with.

The Bank may from time to time, without notice to or the consent of the Holders of the Notes, issue additional Notes, which Notes shall rank pari passu with the Notes and be identical in all respects as the Notes previously issued (other than issue date, issue price and, if applicable, the first interest payment date and the initial interest accrual date) 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. Such additional Notes may have the same or different CUSIP numbers than the Notes issued on the date hereof or no CUSIP number, as the case may be.

REMEDIES

Section 501.    Events of Default.

Notwithstanding any other provisions of the Base Indenture, and for greater certainty, none of (i) the non-payment or default in the payment of interest, or the cancellation of any interest pursuant to Section 206(a) of this Third Supplemental Indenture, on the Notes, (ii) a default in the performance of any other covenant of the Bank in the Indenture or (iii) the occurrence of an NVCC Automatic Conversion shall constitute an Event of Default under the Indenture or the Notes.

Section 502.    Acceleration.

Section 502 of the Base Indenture shall be replaced with the following for purposes of the Notes: If an Event of Default has occurred, and a Trigger Event has not occurred, the entire principal amount of and any Accrued Interest on all of the Outstanding Notes shall become immediately due and payable without any declaration or other act on the part of the Trustee or any Holders of the Notes.

Section 503.    Bank Act Limitation on Payment.

If any provisions contained, from time to time, in the Bank Act or in any rules, regulations, orders or guidelines passed pursuant thereto or in connection therewith or guidelines issued by the Superintendent in relation thereto shall limit the right of the Bank to pay the Securities on or before a date prescribed by such provisions (“Early Payment Restrictions”), Sections 501, 502, 503, 507 and 508 of the Base Indenture shall be subject to such Early Payment Restrictions; provided that so long as any Early Payment Restriction shall be applicable to any Securities, the Trustee shall take such action, as shall not be precluded by the Early Payment Restrictions and as it shall be directed to take by the Holders pursuant to Section 512 of the Base Indenture, to preserve and protect the interests of Holders of Securities then Outstanding to which the Early Payment Restrictions are applicable and to obtain or collect all amounts to which they may be entitled and to distribute the same to them at the earliest time permitted by the Early Payment Restrictions, such action to include, without limitation, the filing

12

and proving of claims with respect to the Securities then outstanding to which the Early Payment Restrictions are applicable in any insolvency or winding up proceedings relating to the Bank and the enforcement of such claims on behalf of the Holders of such Securities. The Bank shall, following any such Early Payment Restriction taking effect, promptly notify the Trustee thereof in writing.

ARTICLE SIX

COVENANTS

Section 601.    Additional Amounts.

(a)    Subject to the Bank’s right to cancel interest payments pursuant to Section 206(a) of this Third Supplemental Indenture, all payments made by the Bank under or with respect to the Notes shall be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge (including penalties, interest and other liabilities related thereto) imposed or levied by or on behalf of the Government of Canada or any province or territory thereof or by any authority or agency therein or thereof having power to tax (“Canadian Taxes”), unless the Bank is required to withhold or deduct Canadian Taxes by law or by the interpretation or administration thereof. If the Bank is so required to withhold or deduct any amount for or on account of Canadian Taxes from any payment made under or with respect to the Notes, the Bank shall pay to each Holder as additional interest such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by each such Holder after such withholding or deduction (and after deducting any Canadian Taxes on such Additional Amounts) shall not be less than the amount such Holder would have received if such Canadian Taxes had not been withheld or deducted, except as described below. The Bank shall, if any Additional Amounts shall become payable, promptly notify the Trustee thereof in writing. However, no Additional Amounts shall be payable with respect to a payment made to a Holder in respect of the beneficial owner thereof:

(i)    with which the Bank does not deal at arm’s-length (for the purposes of the Income Tax Act at the time of the making of such payment;

(ii)    which is a “specified non-resident shareholder” of the Bank for purposes of the Tax Act or a non-resident person not dealing at arm’s-length with a “specified shareholder” (within the meaning of subsection 18(5) of the Tax Act) of the Bank;

(iii)    which is subject to such Canadian Taxes by reason of the holder being a resident, domiciliary or national of, engaged in business or maintaining a permanent establishment or other physical presence in or otherwise having some connection with Canada or any province or territory thereof otherwise than by the mere holding of the Notes or the receipt of payments thereunder;

(iv)    which is subject to such Canadian Taxes by reason of the holder’s failure to comply with any certification, identification, documentation or other reporting requirements if compliance is required by law, regulation, administrative practice or an

13

applicable treaty as a precondition to exemption from, or a reduction in the rate of deduction or withholding of, such Canadian Taxes (provided that the Bank advises the Trustee and the Holders of such Notes then Outstanding of any change in such requirements);

(v)    with respect to any Note presented for payment more than 30 days after the later of (x) the date payment is due and (y) the date on which funds are made available for payment, except to the extent that the holder thereof would have been entitled to such Additional Amounts on presenting same for payment on or before such thirtieth day;

(vi)    with respect to any estate, inheritance, gift, sale, transfer, personal property or similar tax or other governmental charge; or

(vii)    which is a fiduciary or partnership or person other than the sole beneficial owner of such payment to the extent that the Canadian Taxes would not have been imposed on such payment had such holder been the sole beneficial owner of such Notes.

(b)    The Bank shall also make such withholding or deduction and remit the full amount deducted or withheld to the relevant authority in accordance with applicable law.

(c)    The Bank shall furnish to the Holders of the relevant Notes, within 60 days after the date the payment of any Canadian Taxes is due pursuant to applicable law, certified copies of tax receipts or other documents evidencing such payment.

(d)    In any event, no Additional Amounts shall be payable under the provisions described above in respect of any Note in excess of the Additional Amounts which would be required if, at all relevant times, the beneficial owner of such Note were a resident of the United States for purposes of, and was entitled to the benefits of, the Canada-U.S. Income Tax Convention (1980), as amended, including any protocols thereto. As a result of the limitation on the payment of Additional Amounts discussed in the preceding sentence of this Section 601(d), the Additional Amounts received by certain Holders in respect of beneficial owners of the Notes may be less than the amount of Canadian Taxes withheld or deducted and, accordingly, the net amount received by such Holders of those Notes shall be less than the amount such Holders would have received had there been no such withholding or deduction in respect of Canadian taxes.

(e)    Wherever in the Indenture there is mentioned, in any context, the payment of principal, or any interest or any other amount payable under or with respect to a Note, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable as set forth in this Section 601.

(f)    In the event of the occurrence of any transaction or event resulting in a successor to the Bank, all references to Canada in the preceding paragraphs of this subsection shall be deemed to be references to the jurisdiction of organization of the successor entity.

14

(g)    Notwithstanding the provisions of this Section 601, all payments shall be made net of any deduction or withholding imposed or collected pursuant to Sections 1471 through 1474 of the Code, any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code, or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such Sections of the Code (or any law implementing such an intergovernmental agreement) (any such withholding, a “FATCA Withholding Tax”), and no Additional Amounts shall be payable as a result of any such FATCA Withholding Tax.

Section 602.    Restrictions on the Payment of Dividends and Retirement of Shares.

If on any Interest Payment Date, the Bank does not pay in full the applicable interest on the Notes that is due and payable on such Interest Payment Date (whether as a result of cancellation pursuant to Section 206(a) of this Third Supplemental Indenture or otherwise), the Bank shall not (a) declare dividends on the Common Shares or the preferred shares of the Bank or (b) redeem, purchase or otherwise retire any Common Shares or preferred shares of the Bank (except pursuant to any purchase obligation, retraction privilege or mandatory redemption provisions attaching to any preferred shares of the Bank), in each case, until the month commencing immediately after the Bank makes an interest payment in full on the Notes.

ARTICLE SEVEN

CONVERSION INTO COMMON SHARES UPON A TRIGGER EVENT

Section 701.    NVCC Automatic Conversion.

Upon the occurrence of a Trigger Event, each outstanding Note shall automatically and immediately be converted, on a full and permanent basis, without any action on the part of, or the consent of, the Holders of Notes, and as of the start of business on the date on which the Trigger Event occurs, into fully-paid and freely tradable Common Shares, in accordance with this Article Seven (an “NVCC Automatic Conversion”).

Section 702.    Conversion Rate.

The number of Common Shares into which each Note is convertible at the time of an NVCC Automatic Conversion shall be equal to the quotient obtained by dividing (a) the product of the Multiplier and the Note Value, by (b) the Conversion Price.

Section 703.    Time of NVCC Automatic Conversion.

An NVCC Automatic Conversion is deemed to be effected immediately following a Trigger Event and the rights of the Holder of such Notes as the Holder thereof shall cease at such time and the person or persons entitled to receive Common Shares upon an NVCC Automatic Conversion shall be treated for all purposes as having become the holder or holders of record of such Common Shares at such time.

15

Subject to Section 704, as promptly as practicable after the occurrence of a Trigger Event, the Bank shall announce the NVCC Automatic Conversion by way of a press release and shall give notice of the NVCC Automatic Conversion in accordance with the provisions of Section 106 of the Base Indenture to the then Holders of Notes and the Trustee. As promptly as practicable after the NVCC Automatic Conversion, the Bank shall deliver or cause to be delivered certificates representing Common Shares registered in the name of the Holders of Notes, or as such Holder shall have directed, on presentation and surrender of the Global Note in accordance with the applicable procedures of the Depositary, or Notes in certificated form, as the case may be, at the Corporate Trust Office. From and after the NVCC Automatic Conversion, the Notes shall cease to be Outstanding, the Holders thereof shall cease to be entitled to interest thereon, and any certificates representing the Notes shall represent only the right to receive upon surrender thereof certificates representing the applicable number of Common Shares specified in Section 702. An NVCC Automatic Conversion shall be mandatory and binding upon both the Bank and all Holders of the Notes notwithstanding anything else including, without limitation: (a) any prior action to or in furtherance of a redemption of the Notes pursuant to the Indenture; and (b) any delay or impediment to the issuance or delivery of the Common Shares to the Holders of the Notes.

Section 704.    Right Not to Deliver Common Shares.

Upon an NVCC Automatic Conversion, the Bank reserves the right not to deliver some or all, as applicable, of the Common Shares issuable thereupon to any Person whom the Bank has reason to believe is an Ineligible Person. In such circumstances, the Bank shall hold, as agent of all Ineligible Persons, all Common Shares otherwise deliverable to the Ineligible Persons and shall attempt to facilitate the sale of such Common Shares to parties other than the Bank and its Affiliates on behalf of such Ineligible Persons through a registered dealer to be retained by the Bank on behalf of such Ineligible Persons. Those sales (if any) may be made at any time and at any price. The Bank shall not be subject to any liability for failure to sell such Common Shares on behalf of the Ineligible Persons or at any particular price on any particular day. The net proceeds received by the Bank from the sale of any such Common Shares shall be divided among the Ineligible Persons in proportion to the number of Common Shares that would otherwise have been delivered to them upon the NVCC Automatic Conversion after deducting the costs of sale and any applicable withholding taxes. The Bank shall deliver a check or send a wire transfer in immediately available funds representing the aggregate net proceeds to DTC (if the Common Shares are then held in the form of one or more global securities) or in all other cases to such Ineligible Persons in accordance with the regular practices and procedures of DTC or otherwise.

Upon an NVCC Automatic Conversion, the Bank reserves the right not to deliver some or all, as applicable, of the Common Shares to any Person who, by virtue of the operation of the NVCC Automatic Conversion, would become a Significant Shareholder. In such circumstances, the Bank shall hold, as agent of that Person, the Threshold Number of Common Shares otherwise deliverable to such Person, and the Bank shall attempt to facilitate the sale of such Common Shares to parties other than the Bank and its Affiliates on behalf of that Person through a registered dealer to be retained by the Bank on behalf of such Person. Those sales (if any) may be made at any time and at any price. The Bank shall not be subject to any liability for failure to

16

sell any such Common Shares on behalf of that Person or at any particular price on any particular day. The net proceeds received by the Bank from the sale of any such Common Shares shall be delivered to that Person, after deducting the costs of sale and any applicable withholding taxes. The Bank shall deliver a check or send a wire transfer in immediately available funds representing the aggregate net proceeds to DTC (if the Common Shares are then held in the form of one or more global securities) or in all other cases to such Persons in accordance with the regular practices and procedures of DTC or otherwise.

Section 705.    No Entitlement to Interest Following an NVCC Automatic Conversion

Upon an NVCC Automatic Conversion, any Accrued Interest, together with the principal amount of the Notes, shall be deemed paid in full by the issuance of Common Shares upon such conversion and the Holders of Notes shall have no further rights and the Bank shall have no further obligations under the Indenture. If tax is required to be withheld from such payment of interest in the form of Common Shares, the number of Common Shares received by a Holder of Notes shall reflect an amount net of any applicable withholding tax.

Section 706.    Fractional Shares.

In any case where the aggregate number of Common Shares to be issued to a Holder of Notes pursuant to an NVCC Automatic Conversion includes a fraction of a Common Share, such number of Common Shares to be issued to such Holder shall be rounded down to the nearest whole number of Common Shares and no cash payment shall be made in lieu of such fractional Common Share.

Section 707.    Recapitalizations, Reclassifications and Changes in the Common Shares.

In the event of a capital reorganization, consolidation, merger or amalgamation of the Bank or comparable transaction affecting the Common Shares, the Bank shall take necessary action to ensure that Holders of Notes receive, pursuant to an NVCC Automatic Conversion, the number of Common Shares or other securities that such Holders would have received if the NVCC Automatic Conversion occurred immediately prior to the record date for such event.

Section 708.    Adjustments.

(a)    Upon a Common Share Reorganization, the Floor Price shall be adjusted so that it shall equal the price determined by multiplying the Floor Price in effect immediately prior to such effective date or record date of such event by a fraction:

(i)    the numerator of which shall be the total number of Common Shares outstanding on such effective date or record date before giving effect to such Common Share Reorganization; and

(ii)    the denominator of which shall be the total number of Common Shares outstanding immediately after giving effect to such Common Share Reorganization (including, in the case where securities exchangeable for or convertible into Common Shares are distributed, the number, without duplication, of Common Shares that would

17

have been outstanding had all such securities been exchanged for or converted into Common Shares on such effective date or record date).

The adjustment shall be calculated to the nearest one-tenth of one cent provided that no adjustment of the Floor Price shall be required unless such adjustment would require an increase or decrease of at least 1% of the Floor Price then in effect; provided, however, that in such case any adjustment that would otherwise be required then to be made shall be carried forward and shall be made at the time of and together with the next subsequent adjustment which, together with any adjustments so carried forward, shall amount to at least 1% of the Floor Price.

(b)    In any case in which Section 707 or this Section 708 requires that an adjustment shall become effective immediately after a record date for an event referred to therein or herein, the Bank may defer, until the occurrence of such event, issuing to the Holders of any Notes upon a NVCC Automatic Conversion occurring after such record date and before the occurrence of such event, the additional Common Shares issuable upon such conversion by reason of the adjustment required by such event, provided, however, that the Bank shall deliver to such Holder evidence of such Holder’s right to receive such additional Common Shares upon the occurrence of such event and the right to receive any dividends or other distributions made on such additional Common Shares declared in favor of Holders of record of Common Shares on and after the date of the NVCC Automatic Conversion or such later date on which such Holder would, but for the provisions of this Section 708, have become the holder of record of such additional Common Shares.

(c)    If at any time a dispute arises with respect to adjustments provided for in Section 707 or this Section 708, such dispute shall be conclusively determined, subject to the consent if required, of the TSX and any other stock exchange on which the Common Shares are then listed, by the Bank’s Auditors, or if they are unable or unwilling to act, by such other firm of independent chartered accountants as may be selected by action of the Board of Directors of the Bank and any such determination shall be binding upon the Bank, the Holders of the Notes and the other shareholders of the Bank. Such auditors or accountants shall be given access to all necessary records of the Bank.

(d)    If the Bank sets a record date to take any other action and thereafter and before the taking of any action, the Bank abandons its plan to take such other action, then no adjustment in the Floor Price shall be made.

(e)    The Bank shall from time to time, immediately after the occurrence of any event that requires an adjustment or readjustment as provided in Section 707 or this Section 708, deliver an Officer’s Certificate of the Bank to the Trustee specifying the nature of the event requiring the same and the amount of the adjustment or readjustment necessitated thereby and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based, and the Trustee shall be entitled to act and rely upon such Officer’s Certificate of the Bank. Such Officer’s Certificate of the Bank and the amount of the adjustment specified therein shall be conclusive and binding on all parties in interest. Until such Officer’s Certificate of the Bank is received by the Trustee, the Trustee may act and be protected in acting on the presumption that no adjustment has been made or is required. Except in respect of any Common Share Reorganization, the Bank shall forthwith give notice to the Holders of the Notes

18

specifying the event requiring such adjustment or readjustment and the amount thereof, including the resulting Floor Price.

Section 709.    General.

(a)    Notwithstanding any other provision of the Indenture or the Notes, the conversion of the Notes in connection with an NVCC Automatic Conversion shall not be an Event of Default and the only consequence of a Trigger Event shall be the conversion of such Notes into Common Shares.

(b)    The Trustee shall have no duty to determine the occurrence of an NVCC Automatic Conversion or any calculations in connection with any such NVCC Automatic Conversion. The Trustee makes no representation as to the validity or value of any securities or assets issued upon an NVCC Automatic Conversion, and the Trustee shall not be responsible for the Bank’s failure to comply with any provisions of this Article Seven.

Section 710.    Agreements of Holders and Beneficial Owners of Notes.

By acquiring any Note, each Holder and beneficial owner of such Note or any interest therein, including any person acquiring any such Note or interest therein after the date hereof, shall be deemed to have irrevocably acknowledged and agreed with and for the benefit of the Bank and the Trustee as follows:

(a)    that a NVCC Automatic Conversion upon the occurrence of a Trigger Event shall not constitute an Event of Default under the terms of the Notes or the Indenture, and following a NVCC Automatic Conversion no Holder or beneficial owner of the Notes shall have any rights against the Bank with respect to the repayment of the principal of, or interest on, the Notes;

(b)    that, upon a NVCC Automatic Conversion, (i) the Trustee shall not be required to take any further directions from Holders or beneficial owners of the Notes under the Indenture and (ii) the Indenture shall impose no duties upon the Trustee whatsoever with respect to conversion of the Notes into Common Shares upon a Trigger Event;

(c)    that such Holder or beneficial owner authorizes, directs and requests DTC and any direct participant in DTC or other intermediary through which it holds such Notes to take any and all necessary action, if required, to implement the conversion of the Notes into Common Shares upon a Trigger Event without any further action or direction on the part of such Holder or such beneficial owner or the Trustee; and

(d)    that such Holder or beneficial owner acknowledges and agrees that all authority conferred or agreed to be conferred by any Holder and beneficial owner pursuant to the provisions described above shall be binding upon the successors, assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of each Holder and beneficial owner of a Note or any interest therein.

ARTICLE NINE

SUBORDINATION OF NOTES

Section 901.    Applicability of Article Fifteen of the Base Indenture.

Solely for the purposes of the Notes (and not in relation to any other series of Securities), Article Fifteen of the Base Indenture shall be deemed to be replaced in its entirety by this Article Nine.

Section 902.    Notes Subordinate to Deposit Liabilities and Other Indebtedness.

The Notes are direct unsecured debt obligations constituting bank subordinated indebtedness within the meaning of the Bank Act and, in the event of the insolvency or winding-up of the Bank, the Indebtedness evidenced by the Notes shall rank:

(a)    subordinate in right of payment to the prior payment in full of all Indebtedness of the Bank then outstanding (including all Subordinated Indebtedness of the Bank then outstanding other than Deeply Subordinated Indebtedness) (the “Higher Ranked Indebtedness”); and

(b)    in right of payment equally with and not prior to the Deeply Subordinated Indebtedness (other than the Deeply Subordinated Indebtedness which by its terms ranks subordinate to the Notes) of the Bank then outstanding,

whether any such Indebtedness described in clauses (a) and (b) is now outstanding or hereafter incurred.

The Bank agrees and each Holder of any Note, by his, her or its acceptance of such Note, also agrees and shall be deemed conclusively to have agreed, for the benefit of the present and future holders of Higher Ranked Indebtedness, to the provisions of this Article Nine and the Bank and each Holder of any Note by his, her or its acceptance of such Note shall be bound by such provisions.

Section 903.    Further Assurances of Subordination.

Section 905.    Trustee’s Compensation Not Prejudiced.

Nothing in this Article Nine shall apply to amounts due to the Trustee pursuant to other sections in the Indenture.

The Trustee shall not at any time be charged with knowledge of the existence of any facts which would prohibit the making of any payment to or by the Trustee, and the Trustee shall not be required to withhold payment to the Holders of Notes, unless and until the Trustee shall have received written notice thereof at its Corporate Trust Office from the Bank, or from one or more holders of Higher Ranked Indebtedness or from any representative therefor and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of Sections 601 and 603 of the Base Indenture, shall be entitled to assume conclusively that no such facts exist.

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

Section 907     No Fiduciary Duty of Trustee to Holders of Higher Ranked Indebtedness.

The Trustee shall not be deemed to owe any fiduciary duty to the holders of Higher Ranked Indebtedness, and shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to the Holders of the Notes or the Bank or any other Person,

22

cash, property or securities to which any holders of Higher Ranked Indebtedness shall be entitled by virtue of this Article Nine or otherwise. Nothing in this Section 907 shall affect the obligation of any other such Person to hold such payment for the benefit of, and to pay such payment over to, the holders of Higher Ranked Indebtedness or their representative.

(REVERSE OF SECURITY)

This Security is one of a duly authorized issue of securities of the Bank (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of December 12, 2017 (the “Base Indenture”), among the Bank and Wells Fargo Bank, National Association (herein called the “Trustee”, which terms include any successor trustee under the Indenture), as amended and supplemented by the Third Supplemental Indenture, dated as of July 30, 2019, among the Bank and the Trustee (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Bank, the Trustee 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 initially limited in aggregate principal amount to $500,000,000, provided the Bank may, without the consent of any Holder, at any time and from time to time, increase the initial principal amount.

The Securities are the Bank’s direct unsecured obligations, constituting subordinated indebtedness for the purpose of the Bank Act.

The indebtedness evidenced by this Security, to the extent provided in the Indenture, ranks (a) subordinate in right of payment to the prior payment in full of all Higher Ranked Indebtedness and (b) in right of payment equally with and not prior to the Deeply Subordinated Indebtedness (other than the Deeply Subordinated Indebtedness which by its terms ranks subordinate to the Securities) of the Bank, in each case, whether now outstanding or hereafter incurred, 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, her or its behalf to take such actions as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee as his or her attorney-in-fact for any and all such purposes. Each Holder hereof, by his or her acceptance hereof, waives all notice of the acceptance of the subordination provisions contained herein and in the Indenture by each holder of Higher Ranked Indebtedness whether now outstanding or hereafter created, incurred, assumed or guaranteed, and waives reliance by each such holder upon said provisions.

The Bank shall have the sole and absolute discretion at all times and for any reason to cancel (in whole or in part) any interest payment that would otherwise be payable on any Interest Payment Date.

Upon any election by the Bank to cancel (in whole or in part) any interest payment pursuant to Section 206(a) of the Third Supplemental Indenture, the Bank shall give notice to the Holders of this Security through DTC and to the Trustee on or prior to the relevant Interest Payment Date, specifying the amount of the relevant interest cancellation and, accordingly, the amount (if any) of the interest that will be paid on such Interest Payment Date. Failure to provide such notice shall not have any impact on the effectiveness of, or otherwise invalidate, any such cancellation of interest, or give the Holders or beneficial owners of this Security any rights as a result of such failure.

A-4

Interest on this Security shall only be due and payable on an Interest Payment Date to the extent it is not cancelled (in whole or in part) in accordance with the Indenture, and any cancelled interest shall not accumulate or be due and payable at any time thereafter and Holders and beneficial owners of this Security shall have no rights thereto or to receive any additional interest or compensation as a result of such cancellation of interest in respect of this Security.

If on any Interest Payment Date, the Bank does not pay in full the applicable interest on this Security that is due and payable on such Interest Payment Date (whether as a result of cancellation or otherwise), the Bank shall not (a) declare dividends on the Common Shares or the preferred shares of the Bank or (b) redeem, purchase or otherwise retire any Common Shares or preferred shares of the Bank (except pursuant to any purchase obligation, retraction privilege or mandatory redemption provisions attaching to any preferred shares of the Bank), in each case, until the month commencing immediately after the Bank makes an interest payment in full on this Security.

Upon the occurrence of a Trigger Event, each outstanding Security shall automatically and immediately be converted, on a full and permanent basis, without the consent of the Holders thereof, into a number of fully-paid and freely tradable Common Shares of the Bank determined by dividing (a) the product of the Multiplier and the Note Value, by (b) the Conversion Price.

Subject to the Bank’s right to cancel interest payments pursuant to Section 206(a) of the Third Supplemental Indenture, the Bank shall pay Additional Amounts in respect of any withholding or deduction imposed in respect of payments on the Securities pursuant to and subject to the exceptions set forth in Section 601 of the Third Supplemental Indenture.

The Bank may, at its option, redeem the Securities, with the prior written approval of the Superintendent, on not less than 30 days’ and not more than 60 days’ prior notice to the Holders of the Securities, (i) in whole or in part, on any Interest Payment Date on or after the First Reset Date, (ii) in whole but not in part, at any time within 90 days following a Regulatory Event Date and (iii) in whole but not in part, at any time following the occurrence of a Tax Event, in each case, at a Redemption Price equal to 100% of the principal amount thereof, plus any Accrued Interest to, but excluding, the Redemption Date.

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the cancellation hereof.

If an Event of Default with respect to Securities of this series shall occur, and a Trigger Event has not occurred, the principal of the Securities of this series, plus Accrued Interest, if any, shall become immediately due and payable as provided in the Indenture, and the Holder of this Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and Accrued Interest on this Security as provided in the Indenture, and to institute suit for the enforcement of any such payment.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Bank and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the

A-5

Bank and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected, or in certain cases the unanimous consent of each of such Holders. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Bank with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security 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 Security.

For disclosure purposes under the Interest Act (Canada), whenever in the Securities of this series or the Indenture interest at a specified rate is to be calculated on the basis of a period less than a calendar year, the yearly rate of interest to which such rate is equivalent is such rate multiplied by the actual number of days in the relevant calendar year and divided by the number of days in such period.

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

The Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and integral multiples thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

Any Holder who transfers any Security shall provide or cause to be provided to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Internal Revenue Code Section 6045. The Trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

No service charge shall be made for any such registration of transfer or exchange, but the Bank and the Trustee 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 of transfer, the Bank, the Trustee and any agent of the Bank 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 Bank, the Trustee nor any such agent shall be affected by notice to the contrary.

A-6

All terms used in this Security not otherwise defined herein that are defined in the Indenture shall have the meanings assigned to them in the Indenture.
