Notice of such cancellation shall be given to the Bank in writing or by telephone or facsimile confirmed in writing.

7.Indemnification and Contribution. (a) The Bank will indemnify and hold harmless each Underwriter, and each person, if any, who controls any of the Underwriters within the meaning of the Securities Act, against any losses (other than loss of profits), claims, damages or liabilities, joint or several, to which such Underwriter or such controlling person may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus, each as amended or supplemented, or any Issuer Free Writing Prospectus, including the

-11-

Roadshow, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse such Underwriter and such controlling person for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such action or claim, as incurred;provided,however, that the Bank will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Base Prospectus, any Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus, each as amended or supplemented, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Bank by such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 7(b) hereof.

(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Bank and each person, if any, who controls the Bank within the meaning of the Securities Act, against any losses, claims, damages or liabilities to which the Bank or such controlling person may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus, each as amended or supplemented, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus, each as amended or supplemented, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Bank by such Underwriter through the Representatives expressly for use therein; and will reimburse the Bank for any legal or other expenses reasonably incurred by the Bank or such controlling person in connection with investigating or defending any such action or claim, as incurred. The Bank acknowledges and agrees that the information set forth under “Supplemental Plan of Distribution (Conflicts of Interest)” beginning on pageS-42 of the Preliminary Prospectus in the first and second sentences of the third paragraph thereon with respect to the selling concession and reallowance to certain dealers, in the sixth paragraph thereon with respect to stabilization of market prices and in the third and fourth sentences of the seventh paragraph thereon with respect to market making activities of the Underwriters has been provided by the Underwriters to the Bank for use in the Preliminary Prospectus and the Prospectus and constitutes the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof;provided,however, that the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under such subsection for any legal

-12-

expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would, in the judgment of counsel, be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties. Such firm shall be designated in writing by the Underwriters in the case of parties indemnified pursuant to Section 7(a) hereof and by the Bank in the case of parties indemnified pursuant to Section 7(b) hereof. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party (which such consent shall not be unreasonably conditioned, delayed or withheld), effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is an actual or potential party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes (x) no admission of culpability of such indemnified party and (y) an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) If the indemnification provided for in this Section 7 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses (other than loss of profits), claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Bank on the one hand and each Underwriter on the other from the sale of the Securities to which such loss, claim, damage or liability (or action in respect thereof) relates. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Bank on the one hand and each Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Bank on the one hand and each Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the sale of the Securities (before deducting expenses) received by the Bank bear to the total discounts and commissions received by such Underwriter in respect thereof. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading relates to information supplied by the Bank on the one hand or by any Underwriter on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Bank and each Underwriter agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined bypro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending

-13-

any such action or claim. Notwithstanding the provisions of this subsection (d), an Underwriter shall not be required to contribute any amount in excess of the amount by which the total discounts and commissions received by it exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) or found to be grossly negligent by a court of competent jurisdiction shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) The obligations of the Bank under this Section 7 shall be in addition to any liability which the Bank may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Securities Act; and the obligations of each Underwriter under this Section 7 shall be in addition to any liability which such Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Bank and to each person, if any, who controls the Bank within the meaning of the Securities Act.

8.Representations and Indemnities to Survive. The respective indemnities, agreements, representations, warranties and other statements by any Underwriter and the Bank or its officers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation or statement as to the results thereof made by or on behalf of any Underwriter or the Bank or any of its officers or directors or any controlling person, and will survive the delivery of and payment for the Securities.

9.Termination. The Representatives may terminate this Agreement by notice given to the Bank, prior to delivery and payment for the Securities, if at any time after the execution and delivery of this Agreement and prior to such payment and delivery: (i) there shall have occurred any suspension or material limitation in trading in securities generally on the New York Stock Exchange or the Toronto Stock Exchange if the effect of any such event, in the reasonable judgment of the Representatives, makes it impracticable or inadvisable to proceed with the purchase and public offering by the Underwriters of the Securities; (ii) a general moratorium on commercial banking activities in New York is declared by either Federal or New York State authorities or in Toronto is declared either by federal or provincial authorities; (iii) there shall have occurred any outbreak or escalation of hostilities or any calamity or crisis involving the United States or Canada or there shall have been any declaration by the United States or Canada of a national emergency or war, other than any such outbreak, escalation or declaration arising out of or relating to the United States’ war on terrorism that does not represent a significant departure from the conditions that exist on the date of this Agreement; (iv) trading is suspended in the Bank’s securities on the New York Stock Exchange or the Toronto Stock Exchange; (v) there shall have occurred any downgrading, or the Bank shall have received any written notice of any intended downgrading, in the rating accorded the Bank’s debt by Moody’s Investors Service, Inc., a subsidiary of Moody’s Corporation, Standard & Poor’s, a division of McGraw Hill Financial, Inc., Fitch Ratings, a division of The Fitch Group, or DBRS Limited and DBRS, Inc., or any such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, the ratings accorded the Bank’s debt; or (vi) there shall have occurred any material disruption in securities settlement, payment or clearance services in the United States or Canada, if, in the case of clauses (iii) and (vi), the effect of such an event in the reasonable judgment of the Representatives, is to make it impracticable or inadvisable to proceed with the purchase and public offering of the Securities by the Underwriters, on the terms and in the manner contemplated in the Pricing Disclosure Package, as amended or supplemented.

10.Default by an Underwriter. If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase Securities that it has or they have agreed to purchase hereunder on such

-14-

date, and the aggregate principal amount of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more thanone-tenth of the aggregate principal amount of the Securities to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the principal amount of Securities set forth opposite their respective names in Schedule III bears to the aggregate principal amount of Securities set forth opposite the names of all suchnon-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Securities that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess ofone-ninth of such principal amount of Securities without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Securities and the aggregate principal amount of Securities with respect to which such default occurs is more thanone-tenth of the aggregate principal amount of Securities to be purchased on such date, and arrangements satisfactory to the Representatives and the Bank for the purchase of such Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of anynon-defaulting Underwriter or the Bank. In any such case either the Representatives or the Bank shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, the Pricing Disclosure Package or the Prospectus, as amended or supplemented, if applicable, or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

11.Notices. Except as otherwise specifically provided herein, all statements, requests, notices and advices hereunder shall be in writing, or by telephone if promptly confirmed in writing, and if to the Representatives, shall be sufficient in all respects when delivered or sent by facsimile transmission or registered mail as set forth inAnnex IIIhereto under such Representative’s name, and if to the Bank shall be sufficient in all respects when delivered or sent by registered mail to Bank of Montreal, 100 King Street West, 1 First Canadian Place, 10th Floor, Toronto, Ontario, Canada M5X 1A1, Facsimile Transmission: (416)867-7193, Attention: Senior Vice President and Treasurer, with a copy to Osler, Hoskin & Harcourt LLP, 100 King Street West, Suite 6600, Toronto, Ontario, Canada M5X 1B8, Facsimile Transmission: (416)862-6666, Attention: Rick Fullerton.

No purchaser of any of the Securities through or from any Underwriter hereunder shall be deemed a successor or assign by reason of such purchase.

13.No fiduciary duty. The Bank acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement is anarm’s-length commercial transaction between the Bank, on the one hand, and the Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Bank, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Bank with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Bank on other matters) or any other obligation to the Bank except the obligations expressly set forth in this Agreement, (iv) the Underwriters may have interests that differ from the interests of the Bank and (v) the Bank has consulted its own legal and financial advisors to the extent it deemed appropriate. The Bank agrees that it will not claim that the

-15-

Underwriters, or any of them, have rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Bank, in connection with such transaction or the process leading thereto.

14.Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Bank and the Underwriters, or any of them, with respect to the subject matter hereof.

The obligation of the Bank with respect to any sum due from it to any Underwriter or any person controlling any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first Business Day following receipt by such Underwriter or controlling person of any sum in such other currency, and only to the extent that such Underwriter or controlling person may in accordance with normal banking procedures purchase United States dollars with such other currency.

	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. “H.15” means the statistical release designated as such, or any successor publication, published by the Board of Governors of the United States Federal Reserve System, and “most recent H.15” means the H.15 published closest in time but prior to the close of business on the second business day prior to the applicable Reset Date.
Interest Payment Dates:	Subject to the Bank’s right to cancel interest payments, interest on the Notes will be payable semi-annually in arrears on February 25 and August 25 of each year (each, an “Interest Payment Date”), commencing February 25, 2020 (long first coupon).
Reset Dates:	August 25, 2024 and each fifth anniversary date thereafter (each such date, a “Reset Date”).

Any cancelled interest payments will not be cumulative. The Bank has the sole and absolute discretion at all times and for any reason to cancel (in whole or in part), with notice to the holders of the Notes, any interest payment that would otherwise be payable on any Interest Payment Date. As a result, you may not receive any interest on any Interest Payment Date or at any other times, and you will have no claims whatsoever in respect of that cancelled interest.

If no such trading prices are available, Current Market Price shall be the Floor Price. “Floor Price” means the U.S. dollar equivalent of CAD$5.00 converted into U.S. dollars at the Prevailing Rate on the day immediately prior to the date on which the Trigger Event occurs, subject to adjustment in the event of (i) the issuance of

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 to be made will be carried forward and will be made at the time of and together with the next subsequent adjustment which, together with any adjustments so carried forward, will amount to at least 1% of the Floor Price. “Multiplier” means 1.25. “Note Value” means, in respect of each Note, the principal amount of such Note plus any accrued and unpaid interest on such Note to, but excluding, the date of the Trigger Event (except to the extent such unpaid interest was cancelled). “Prevailing Rate” means, in respect of any currencies on any day, the spot rate of exchange between the relevant currencies prevailing as at or about 12:00 noon (New York time) on that date as appearing on or derived from the Relevant Page or, if such a rate cannot be determined at such time, the rate prevailing as at or about 12:00 noon (New York time) on the immediately preceding day on which such rate can be so determined or, if such rate cannot be so determined by reference to the Relevant Page, the rate determined in such other manner as an Independent Financial Adviser (as defined in the Prospectus Supplement) shall consider in good faith appropriate. “Relevant Page” means the relevant page on Bloomberg (or such other information service provider) that displays the relevant information.

SCHEDULE I-5

	of the opinion that the Bank has ceased, or is about to cease, to be viable and that, after the conversion of the Notes and all other contingent instruments issued by the Bank and taking into account any other factors or circumstances that are considered relevant or appropriate, it is reasonably likely that the viability of the Bank will be restored or maintained; or •  a federal or provincial government in Canada publicly announces that the Bank has accepted or agreed to accept a capital injection, or equivalent support, from the federal government or any provincial government or political subdivision or agent or agency thereof without which the Bank would have been determined by the Superintendent to benon-viable.
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 or otherwise), the Bank will 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.

Neither the failure to make a payment on the Notes when due (including any interest payment, whether as a result of cancellation or otherwise) nor an NVCC Automatic Conversion will constitute an Event of Default. If an Event of Default has occurred, and a Trigger Event has not occurred, the entire principal amount of and accrued and unpaid interest on all of the Notes (except to the extent such unpaid interest was cancelled) will become immediately due and payable without any declaration or other act on the part of the Trustees or any holders of the Notes.
