(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 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.

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 premium or 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.

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 andnon-assessable 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) 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.

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 or 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 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 and unpaid 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 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 nearestone-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 Toronto Stock Exchange 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 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.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

Dated: October 5, 2018


WELLS FARGO BANK, NATIONAL ASSOCIATION
As Trustee



By:


Authorized Signatory

(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 Second Supplemental Indenture, dated as of October 5, 2018, among the Bank and the Trustee (the “SecondSupplementalIndenture” 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 $850,000,000, 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 is, to the extent provided in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness 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 herattorney-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 Senior Indebtedness whether now outstanding or hereafter created, incurred, assumed or guaranteed, and waives reliance by each such holder upon said provisions.

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 that number of fully-paid Common Shares of the Bank determined by dividing (a) the product of the Multiplier and the Note Value, by (b) the Conversion Price.

The Bank may, at its option, redeem the Notes with the prior written approval of the Superintendent, in whole but not in part, on not less than 30 days’ and not more than 60 days’ prior notice to the Holders of the Notes, at any time within 90 days following a Regulatory Event Date, at a Redemption Price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to, but excluding, the Redemption Date. The Bank may, at its option, redeem the Notes, with the prior written approval of the Superintendent, in whole but not in part, on not less than 30 days’ and not more than 60 days’ prior notice to the Holders of the Notes, at any time following the occurrence of a Tax Event, at a Redemption Price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to, but excluding, the Redemption Date. The Bank may, at its option, redeem the Notes, with the prior written approval of the Superintendent, in whole but not in part, on not less than 30 days’ and not more than 60 days’ prior notice to the

Holders of the Notes, on the Reset Date, at a Redemption Price equal to 100% of the principal amount thereof, plus accrued and unpaid interest to, but excluding, the Redemption Date.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

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 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.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee security or indemnity reasonably satisfactory to the Trustee, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 90 days after receipt of such notice, request and offer of indemnity.
