Section 1.03      Payment of Principal and Interest.

A.)            Interest and Maturity.

The Notes shall be known and designated as the “6.625% Fixed-to-Fixed Rate Junior Subordinated Notes due 2057” of the Corporation. The principal of the Notes shall be due on the Maturity Date (unless earlier redeemed). The outstanding Notes will bear interest from, and including, the Issue Date to, but excluding, the Initial Interest Rate Reset Date, at a rate of 6.625% per annum. From, and including, the Initial Interest Rate Reset Date to but excluding the Maturity Date, the outstanding Notes will bear interest at a rate per annum equal to the 5-Year Treasury Rate (subject to reset on each applicable Interest Rate Reset Date) plus 2.016%; provided that the interest rate during any Interest Rate Reset Period will not reset below 6.625% (which equals the initial interest rate on the Notes). The 5-Year Treasury Rate for computing interest on the outstanding Notes from and after the Initial Interest Rate Reset Date will be calculated as of the applicable Interest Rate Calculation Date for each Interest Rate Reset Period.

Interest on the Notes is payable semi-annually in arrears on each Interest Payment Date (or, if such day is not a Business Day, the next following Business Day) in each year, commencing on March 30, 2027 in equal installments (except for the first interest payment which will be $34.78 per $1,000 of the principal amount of Notes, payable on March 30, 2027 and representing interest accrued from and including September 21, 2026 to, but excluding, March 30, 2027).

The Corporation has the right to defer interest payments pursuant to Section 1.03B.) of this Second Supplemental Indenture. Subject to the Deferral Right (as defined below) in Section 1.03B.) of this Second Supplemental Indenture, accrued interest shall be paid semi-annually in arrears on each Interest Payment Date to the Person or Persons in whose name the Notes are registered on the Regular Record Date for such Interest Payment Date; provided that interest payable at the Maturity Date or on a Redemption Date as provided herein shall be paid to the Person to whom principal is payable. Any such interest that is not so punctually paid or duly provided for shall forthwith cease to be payable to the Holders on such Regular Record Date and may either be paid to the Person or Persons in whose name the Notes are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the U.S. Trustee (“Notes Special Record Date”), notice whereof shall be given to Holders of the Notes not less than 10 days prior to such Notes Special Record Date, or, in the case of Deferred Interest, the Regular Record Date immediately preceding the Interest Payment Date on which such Deferred Interest is paid by the Corporation pursuant to Section 1.03B.) of this Second Supplemental Indenture, or shall otherwise be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange, if any, on which the Notes may be listed, and upon such notice as may be required by any such exchange, all as more fully provided in the Base Indenture.

Interest for any period will be calculated on the basis of a 360-day year consisting of twelve 30-day months. If an Interest Payment Date falls on a day that is not a Business Day, the Interest Payment Date will be postponed to the next succeeding day that is a Business Day, and no further interest will accrue in respect of such postponement. For disclosure purposes under the Interest Act (Canada), whenever in the Indenture or any Securities issued hereunder 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.

B.)           Deferral Right.

So long as no Event of Default has occurred and is continuing, the Corporation may elect, at its sole option, at any date other than an Interest Payment Date, to defer the interest payable on the Notes (the “Deferral Right”) on one or more occasions for up to 10 consecutive years (a “Deferral Period”). There is no limit on the number of Deferral Periods that may occur. Any such election by the Corporation to defer the payment of interest will not constitute an Event of Default, a default or any other breach under the Notes or the Indenture. Any installment of interest whose payment is deferred pursuant to the Deferral Right provided in this Section 1.03B.) will accrue interest at a per annum rate equal to the interest rate then applicable to the Notes (to the extent permitted by applicable law), compounding on each subsequent Interest Payment Date, until paid. A Deferral Period terminates on any Interest Payment Date where the Corporation pays all accrued and unpaid interest subject to such Deferral Period on the Notes on such date. No Deferral Period may extend beyond the Maturity Date and all accrued and unpaid interest on the Notes as of the Maturity Date, if any, will be due and payable on the Maturity Date. The Corporation will give the Trustees and the Holders of the Notes notice of its election to commence or continue a Deferral Period at least 10 but not more than 60 days prior to the next Interest Payment Date.

C.)           Calculation Agent.

The Corporation shall appoint a Calculation Agent on or prior to the Interest Rate Calculation Date in respect of the Initial Interest Rate Reset Date; provided, however, that the Corporation shall not be required to appoint a Calculation Agent if the Corporation has elected to redeem all of the Outstanding Notes on or prior to the Initial Interest Rate Reset Date; provided, further, that, if the Corporation has so elected but does not redeem all of the Outstanding Notes on or prior to the Initial Interest Rate Reset Date, the Corporation shall appoint a Calculation Agent not later than the Business Day immediately following the Initial Interest Rate Reset Date.

The Calculation Agent will determine the applicable interest rate for each Interest Rate Reset Period as of the applicable Interest Rate Calculation Date. Promptly upon such determination, the Calculation Agent, if other than the Corporation or an Affiliate of the Corporation, will notify the Corporation of the applicable interest rate for the relevant Interest Rate Reset Period and, provided neither Trustee is the Calculation Agent, the Corporation will then promptly notify the Trustees of such interest rate.

The Calculation Agent’s determination of any interest rate and its calculation of the amount of interest for any Interest Rate Reset Period beginning on or after the Initial Interest Rate Reset Date will be conclusive and binding absent manifest error, may be made in the Calculation Agent’s sole discretion and, notwithstanding anything to the contrary herein or any other documentation relating to the Notes, will become effective without consent from any other Person or entity. Such determination of any interest rate and calculation of the amount of interest will be on file at the Corporation’s principal offices and will be made available to any Holder of Notes upon request.

D.)           General.

Payment of the principal of, premium, if any, Additional Amounts, if any, and interest on the Notes shall be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. Payments of principal of, premium, if any, Additional Amounts, if any, and interest on Notes represented by a Global Security shall be made by wire transfer of immediately available funds to the Holder of such Global Security, provided that, in the case of payments of principal and premium, if any, such Global Security is first surrendered to the Paying Agent. If any of the Notes are no longer represented by a Global Security, (i) payments of principal, premium, if any, and interest due at the Maturity Date or earlier redemption of the Notes shall be made at the office of the Paying Agent upon surrender of the Notes to the Paying Agent and (ii) payments of interest shall be made, at the option of the Corporation, subject to such surrender where applicable, by (A) check mailed to the address of the Person entitled thereto as such address shall appear in the Register or (B) wire transfer at such place and to such account at a banking institution in the United States as may be designated in writing to the Trustees at least five Business Days prior to the date for payment by the Person entitled thereto.

The Notes may be redeemed at the option of the Corporation at the prices, at the times and on such other terms and conditions as are specified in Section 1.07 of this Second Supplemental Indenture. The Corporation shall not be obligated to redeem, purchase or repay the Notes pursuant to any sinking fund or analogous provisions or at the option of a Holder of the Notes.

The Notes shall be subject to the covenants (and the related definitions) set forth in Article 10 of the Base Indenture and, except as otherwise provided herein, to any other covenant in the Indenture, and to the defeasance and discharge provisions set forth in Article 12 of the Base Indenture.

Section 1.04      Additional Notes.

An unlimited aggregate principal amount of the Notes may be authenticated and delivered under this Second Supplemental Indenture (of which $500,000,000 is being issued, authenticated and delivered on the date hereof), including Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to Section 304, 305, 306, 906 or 1106 of the Base Indenture.

The Corporation may, from time to time, without notice to or the consent of the Holders, create and issue, pursuant to the Indenture and in accordance with applicable laws and regulations, additional notes (“Additional Notes”) maturing on the same maturity date as the Notes and having the same terms and conditions under the Indenture as the Notes at the time outstanding (except for the issue date and, if applicable, the date of the first payment of interest thereon) so that such Additional Notes will be consolidated and form a single series with the Notes at the time outstanding for all purposes under the Indenture, including with respect to waivers, amendments, redemptions and offers to purchase; provided that, if any such Additional Notes are not fungible with the Notes for United States federal income tax purposes, such Additional Notes will have a separate CUSIP, ISIN or other identifying number.

Section 1.05      Ranking & Subordination. The Notes will be unsecured, subordinated obligations of the Corporation. The payment of principal, premium (if any) and interest on the Notes, to the extent provided in Section 1.03 of this Second Supplemental Indenture, will be subordinated in right of payment to the prior payment in full of all Senior Indebtedness. The Notes will be structurally subordinated to all debt and other liabilities and any preference or preferred shares of the Corporation’s subsidiaries.

Section 1.06      Form and Denominations. The Notes will be issued in the form of one or more fully registered Global Securities to be held by, or on behalf of, the Depositary (which initially shall be DTC) or its nominee. The Notes will be issued only in fully registered form, without coupons, in minimum denominations of $2,000 or any integral multiple of $1,000 in excess thereof.

Section 1.07      Redemption.

The Corporation may, at its option, on giving not more than 60 days’ nor less than 10 days’ prior notice to the Holders, redeem the Notes, in whole at any time or in part from time to time, (i) on any day in the period commencing on (and including) December 31, 2031 (the date falling 90 days prior to the Initial Interest Rate Reset Date) and ending on (and including) the Initial Interest Rate Reset Date and (ii) thereafter, on any Interest Rate Reset Date or any Interest Payment Date, in each case, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed together with accrued and unpaid interest (including Deferred Interest, if any) thereon to, but excluding, the date fixed for redemption. For greater clarity, if there is a Tax Event or Rating Event on or after December 31, 2031, the Corporation may optionally redeem the Notes in accordance with the optional redemption right in this Section 1.07A.) of this Second Supplemental Indenture without regard to the additional rights of redemption provided for such Tax Event or Rating Event, as applicable, in Section 1.07B.) and C.), respectively, of this Second Supplemental Indenture.

At the Corporation’s discretion, any redemption or notice of any redemption of the Notes, in whole or in part, may be subject to one or more conditions precedent, including completion of an equity or other securities offering, an incurrence of indebtedness or other financing, or any other corporate transaction or event. Notice of any redemption in respect thereof may, at the Corporation’s discretion, be given prior to the completion of one or more of the transactions or events upon which the redemption is conditioned and such redemption may be partial as a result of only some of the conditions being satisfied. If such redemption is subject to the satisfaction of one or more conditions precedent, the related notice must describe each such condition, and if applicable, state that, in the Corporation’s discretion, such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the applicable date fixed for redemption. The Corporation may provide in such redemption notice that payment of the Redemption Price and other amounts owing for the redemption of any Outstanding Notes and performance of the Corporation’s obligations with respect to such redemption may be performed by another Person.

If the Notes are redeemed in part, the notice of redemption will state the portion of the principal amount thereof to be redeemed. A replacement Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note; provided, however, that, notwithstanding Section 1106 of the Base Indenture, in the case of a Note represented by a Global Security, an appropriate notation may instead be made on such Note to decrease the principal amount thereof to an amount equal to the unredeemed portion thereof, rather than authenticating and delivering to the Holder of such Note a new Note in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Note so surrendered.

In the event that the Corporation redeems or purchases any of the Notes, the Corporation intends (without thereby assuming a legal obligation) to do so only to the extent the aggregate redemption or purchase price is equal to or less than the net proceeds, if any, received by the Corporation from new issuances of securities during the period commencing on the 365th or 366th calendar day, depending upon the actual number of days in the applicable year, prior to the date of such redemption or purchase of Notes which are assigned by a Nationally Recognized Statistical Ratings Organization at the time of sale or issuance, an aggregate equity credit that is equal to or greater than the equity credit assigned to the Notes to be redeemed or purchased (but taking into account any changes in hybrid capital methodology or another relevant methodology or the interpretation thereof since the issuance of the Notes), unless the Notes are redeemed pursuant to a Rating Event or a Tax Event.

At any time within 90 days following the occurrence of a Tax Event, the Corporation may, at its option, on giving not more than 60 days’ nor less than 10 days’ prior written notice to the Holders, redeem all (but not less than all) of the Notes at a Redemption Price equal to 100% of the principal amount thereof, together with accrued and unpaid interest (including Deferred Interest, if any) thereon to, but excluding, the date fixed for redemption.

At any time within 90 days following the occurrence of a Rating Event, the Corporation may, at its option, on giving not more than 60 days’ nor less than 10 days’ prior notice to the Holders, redeem all (but not less than all) of the Notes at a Redemption Price equal to 102% of the principal amount thereof, together with accrued and unpaid interest (including Deferred Interest, if any) thereon to, but excluding, the date fixed for redemption.

For avoidance of doubt, the Corporation may purchase or otherwise acquire, at any time or from time to time, Securities of any series by means other than a redemption, whether pursuant to an offer to purchase, open market purchase, private contract or otherwise, at such prices as the Corporation may determine in its sole discretion.

Section 1.08      Dividend Stopper Undertaking.

Unless the Corporation has paid all interest on the Notes that, at such time, has accrued and is payable (including Deferred Interest, if any), the Corporation will not (i) declare any dividends on Dividend Restricted Shares (as defined below) (other than stock dividends on Dividend Restricted Shares) or pay any interest on any Parity Notes (as defined below), (ii) redeem, purchase or otherwise retire for value any Dividend Restricted Shares or Parity Notes (unless such redemption, purchase or retirement for value is a Permitted Purchase (as defined below)), or (iii) make any payment to holders of any of the Dividend Restricted Shares or any of the Parity Notes in respect of dividends not declared or paid on such Dividend Restricted Shares or interest not paid on such Parity Notes, respectively.

For purposes of this Section 1.08:

“Dividend Restricted Shares” means, collectively, the Preference Shares and Common Shares.

“Permitted Purchase” means a redemption, purchase or other retirement for value by or on behalf of the Corporation of any Dividend Restricted Shares or Parity Notes (a) pursuant to any purchase obligation, sinking fund, retraction privilege or mandatory redemption provisions attaching to, or on maturity of, any series of Dividend Restricted Shares or Parity Notes, including accrued and unpaid dividends or interest payable in connection therewith, or (b) with respect to Dividend Restricted Shares, (i) out of the net cash proceeds of a substantially concurrent issuance and sale of, or made in exchange for (including by using), Dividend Restricted Shares or a substantially concurrent net cash capital contribution received by the Corporation (other than from a subsidiary of the Corporation), (ii) deemed to occur upon the exercise or exchange of options, warrants or other convertible or exchangeable securities, including Dividend Restricted Shares, as applicable, to the extent such Dividend Restricted Shares represent all or a portion of the exercise, conversion or exchange price thereof, together with any withholding to pay for the taxes payable in connection therewith and accrued and unpaid dividends payable in connection therewith, (iii) effected by or on behalf of the Corporation or any of its subsidiaries pursuant to the terms of any securities based compensation arrangement of the Corporation and/or any of its subsidiaries, currently in effect or adopted from time to time, which provides for market purchases of Common Shares to settle entitlements under such securities based compensation arrangement or (iv) cash payments in lieu of issuing fractional shares in connection with share dividends, splits or business combinations or the exercise of warrants, options or other securities convertible into or exchangeable for Dividend Restricted Shares.

The Corporation will promptly notify the Trustees in writing of any such waiver or the revocation of any such waiver.

Section 1.09      Global Securities. Except under the limited circumstances described below, Notes represented by a Global Security or Global Securities shall not be exchangeable for, and shall not otherwise be issuable as, Notes in definitive form. The Global Securities described in this Article I of this Second Supplemental Indenture may not be transferred except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or to a successor Depositary or its nominee.

A Global Security representing the Notes shall be exchangeable for Notes registered in the names of Persons other than the Depositary or its nominee only if (i) the Depositary notifies the Corporation that it is unwilling or unable to discharge its responsibilities properly as a Depositary for such Global Security and no successor Depositary shall have been appointed by the Corporation within 90 days of receipt by the Corporation of such notification, or if at any time the Depositary ceases to be eligible to be a clearing agency registered under the Exchange Act (a “Clearing Agency”) in accordance with the applicable securities laws at a time when the Depositary is required to be so registered to act as such Depositary and no successor Depositary shall have been appointed by the Corporation within 90 days after it becomes aware of such cessation, (ii) an Event of Default has occurred and is continuing with respect to the Notes and beneficial owners of a majority in aggregate principal amount of the Notes represented by Global Securities advise the Depositary to cease acting as Depositary, or (iii) the Corporation in its sole discretion, and subject to the procedures of the Depositary, determines that such Global Security shall be so exchangeable. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Notes registered in such names as the Depositary shall direct.

Notwithstanding anything to the contrary in Section 303 of the Base Indenture, the signature of any officer of the Corporation and any authorized signatory of the U.S. Trustee and the Canadian Co-Trustee referred to therein on any Global Security representing the Notes may be a manual, facsimile or electronic signature.

DTC shall initially act as the Depositary with respect to the Notes and the U.S. Trustee shall initially serve as Paying Agent and Custodian with respect to the Notes, with the Place of Payment initially being the Corporate Trust Office of the U.S. Trustee.

For purposes of this Second Supplemental Indenture, Section 1202(2) of the Base Indenture shall be deemed to include the Corporation’s obligations with respect to such Securities under Section 307 of the Base Indenture.

B.)            Covenant Defeasance

In the case of Covenant Defeasance pursuant to Section 1203 of the Base Indenture, the Corporation shall have delivered to the Trustees (i) an opinion of counsel in the United States to the effect that the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; and (ii) an opinion of counsel in Canada or an advance tax ruling from the Canada Revenue Agency (or successor agency) to the effect that the Holders of outstanding Notes will not recognize income, gain or loss for Canadian income tax purposes as a result of such Covenant Defeasance and will be subject to Canadian federal income tax on the same amounts, in the same manner, and at the same times as would have been the case if such Covenant Defeasance had not occurred.

Section 1.13      Events of Default.

Notwithstanding anything to the contrary contained in the Base Indenture, Section 501(3) of the Base Indenture shall not apply to the Notes and shall not constitute or give rise to an Event of Default with respect to the Notes for purposes of the Indenture.

With respect to the Notes, Section 501(2) of the Base Indenture shall include a default in the payment of the Redemption Price on the Notes, including any accrued and unpaid interest (including Deferred Interest, if any), when it becomes due and payable. For greater certainty, nothing in this Section shall constitute an amendment to the Base Indenture or affect the applicability of Section 501(3) of the Base Indenture to any other series of Securities issued thereunder.

Section 1.14      Consolidation, Merger, Conveyance or Transfer.

In the case of a consolidation, merger, arrangement or amalgamation of the Corporation with or into any other Person, or the conveyance or transfer of all or substantially all of the properties and assets of the Corporation to any other Person, in accordance with Section 801 of the Base Indenture, the Corporation covenants and agrees that the successor Person formed by such consolidation, or into which the Corporation shall have been merged, arranged or amalgamated, or the Person which shall have acquired such properties and assets shall be organized under the laws of Canada, or any province or territory thereof, the United States of America, or any state or the District of Columbia.

Section 2.03      Payment Prior to Dissolution or Default. Nothing contained in this Article II of this Second Supplemental Indenture or elsewhere in the Indenture, or in any of the Notes, shall prevent (a) the Corporation, at any time except under the conditions described in Section 2.02 of this Second Supplemental Indenture or during the pendency of any dissolution or winding up or total or partial liquidation or reorganization proceedings therein referred to, from making payments at any time of principal of (or premium, if any) or interest on the Notes or from depositing with the Trustees or any Paying Agent moneys for such payments, or (b) the application by the Trustees or any Paying Agent of any moneys deposited with it under the Indenture to the payment of or on account of the principal of (or premium, if any) or interest on the Notes to the Holders entitled thereto if such payment would not have been prohibited by the provisions of Section 2.02 of this Second Supplemental Indenture on the day such moneys were so deposited.

Notwithstanding the provisions of Section 2.01 of this Second Supplemental Indenture or any other provision of the Indenture, the Trustees and any Paying Agent shall not be charged with knowledge of the existence of any Senior Indebtedness, or of the occurrence of any default with respect to Senior Indebtedness of the character described in Section 2.02 of this Second Supplemental Indenture, or of any other facts which would prohibit the making of any payment of moneys to or by the Trustees or such Paying Agent, unless and until the Trustees shall have received, no later than three Business Days prior to such payment, written notice thereof from the Corporation or from a holder of such Senior Indebtedness and the Trustees shall not be affected by any such notice which may be received by it on or after such third Business Day.

The Trustees shall be entitled to all of the rights set forth in this Article II of this Second Supplemental Indenture in respect of any Senior Indebtedness at any time held by it to the same extent as any other holder of Senior Indebtedness, and nothing in the Indenture shall be construed to deprive the Trustees of any of their rights as such holder.

Section 2.06      Article II Not to Prevent Events of Default. The failure to make a payment on account of principal of, premium, if any, or interest on the Notes by reason of any provision of this Article II of this Second Supplemental Indenture shall not be construed as preventing the occurrence of an Event of Default under Section 501 of the Base Indenture or an event which with the giving of notice or lapse of time, or both, would become an Event of Default or in any way prevent the Holders of the Notes from exercising any right hereunder other than the right to receive payment on the Notes.

Section 2.07      No Fiduciary Duty of Trustees to Holders of Senior Indebtedness. The Trustees shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness, and shall not be liable to any such holders (other than for its willful misconduct, bad faith or gross negligence) if either of them shall in good faith mistakenly pay over or distribute to the Holders of the Notes or the Corporation or any other Person, cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article II of this Second Supplemental Indenture or otherwise.

Article III
MISCELLANEOUS PROVISIONS

Section 3.01      Recitals by the Corporation. The recitals in this Second Supplemental Indenture are made by the Corporation only and not by the Trustees, and all of the provisions contained in the Base Indenture in respect of the rights, privileges, immunities, powers and duties of the Trustees shall be applicable in respect of the Notes and this Second Supplemental Indenture as fully and with like effect as if set forth herein in full.

Section 3.02      Ratification and Incorporation of Base Indenture. As supplemented hereby, the Base Indenture is in all respects ratified and confirmed, and the Base Indenture and this Second Supplemental Indenture shall be read, taken and construed as one and the same instrument; provided that the provisions of this Second Supplemental Indenture are expressly and solely for the benefit of the Holders of the Notes.

Section 3.03      Executed in Counterparts. This Second Supplemental Indenture may be executed in several counterparts, each of which shall be deemed to be an original, and such counterparts shall together constitute but one and the same instrument.

Section 3.04      Appointment of Agent.

Section 3.07      Holder Direction. Without limiting the generality of Section 104 of the Base Indenture or any other applicable provision of this Second Supplemental Indenture or the Base Indenture, a direction of a Holder (a “Holder Direction”) in respect of a consent, approval or waiver given by a Holder of a Global Security (whether such Holder Direction is given by the Holder of such Global Security or by one or more Beneficial Owners in respect of any such Global Security that are appointed as the proxies or agents of such Holder) may be given by electronic transmission or otherwise in accordance with the procedures of the Clearing Agency or Depositary for such Global Security, including through DTC’s facilities or a similar system used by such Clearing Agency or Depositary (any Holder Direction so given is referred to herein as an “Electronic Holder Direction”). For greater certainty, it shall not be necessary for an Electronic Holder Direction to be given pursuant to an instrument in writing that is signed or guaranteed by such Holder or Beneficial Owners, as applicable. A Holder Direction in respect of a Global Security may be proved by, among other things, a report or other record (a) generated by the Clearing Agency or Depositary for such Global Security or (b) signed by the tabulation agent or other agent engaged by the Corporation for tabulating or compiling the consents, approvals, waivers or votes, as applicable, in respect of the Act for which the Holder Direction is sought (such report or other record, a “Consent Report”) and the Trustees and the Corporation shall each be entitled to receive and rely upon such Consent Report as if it was an instrument in writing signed by the Holder of such Global Security or the proxy or agent of such Holder, as applicable. By the taking of a position in a Global Security, each Beneficial Owner in respect of such Global Security acknowledges and agrees that (i) the Trustees and the Corporation may elect to use DTC’s facilities (or any other electronic system used by the Clearing Agency or Depositary for clearing or settlement of such Global Security) to obtain an Electronic Holder Direction and (ii) the Trustees and the Corporation shall have no liability for electing to use such system or relying on any Consent Report certifying or evidencing such Electronic Holder Direction.

For greater certainty, and without limiting the generality of this Section 3.07 of this Second Supplemental Indenture or Section 104 of the Base Indenture, a Clearing Agency or Depositary that is a Holder of a Global Security may appoint Beneficial Owners with respect to any such Global Security as the proxy or agent of such Holder through such Clearing Agency’s or Depositary’s procedures and it shall not be necessary for such appointment to be pursuant to an instrument in writing that is signed by the Holder. If a Beneficial Owner is appointed by a Holder as its proxy or agent for purposes of giving a Holder Direction then that Beneficial Owner shall be deemed to be the duly appointed proxy and agent of such Holder for purposes of such Holder Direction to the extent provided in such appointment.

Section 3.08      Agreement to Certain Tax Treatment. The Corporation and each beneficial owner of the Notes, by acquiring a beneficial interest therein, acknowledges and agrees that it intends for the Notes to constitute indebtedness for U.S. federal, state and local tax purposes and will treat the Notes as indebtedness for all applicable U.S. federal, state and local tax purposes.

Section 3.09      Electronic Communications.

For purposes of the Notes, the last paragraph of Section 105 of the Base Indenture is deleted in its entirety and replaced with the following text:

“The Trustees shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to this Agreement and delivered using Electronic Means; provided, however, that the Corporation shall provide to the Trustees incumbency certificates listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificates shall be amended by the Corporation whenever a person is to be added or deleted from the listing. If the Corporation elects to give the Trustees Instructions using Electronic Means and the Trustees in their discretion elect to act upon such Instructions, the Trustees understanding of such Instructions shall be deemed controlling. The Corporation understands and agrees that the Trustees cannot determine the identity of the actual sender of such Instructions and that the Trustees shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to them have been sent by such Authorized Officer. The Corporation shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustees and that the Corporation and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Corporation. The Trustees shall not be liable for any losses, costs or expenses arising directly or indirectly from their reliance upon and compliance with such Instructions notwithstanding such Instructions conflict or are inconsistent with subsequent written instructions. The Corporation agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustees and, including without limitation the risk of the Trustees acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that they are fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustees and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Corporation; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustees immediately upon learning of any compromise or unauthorized use of the security procedures.

"Electronic Means" shall mean the following communications methods: e-mail, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustees, or another method or system specified by the Trustees as available for use in connection with its services hereunder.”

Section 3.10      FATCA.

Solely for the benefit of the U.S. Trustee in order to assist it in complying with Sections 1471 through 1474 of the Internal Revenue Code and the rules and regulations thereunder (as in effect from time to time, collectively, “FATCA”), the Corporation agrees (i) to use commercially reasonable efforts to provide to the U.S. Trustee upon its reasonable written request such information in the Corporation’s possession about holders or other applicable parties and/or transactions (including any modification to the terms of such transactions) so the U.S. Trustee can determine whether it has tax related obligations under FATCA and (ii) that the U.S. Trustee shall be entitled to make any withholding or deduction from payments under this Indenture to the extent necessary to comply with FATCA and that the U.S. Trustee shall not have any liability in respect of any withholding or deduction from payment under this Indenture to the extent such withholding or deduction is necessary to comply with FATCA.

Section 3.11      OFAC.

The Corporation covenants and represents that neither it nor any of its affiliates, subsidiaries, directors or officers are the target or subject of any sanctions enforced by the United States (including, the Office of Foreign Assets Control of the U.S. Department of the Treasury (“OFAC”)), the United Nations Security Council, the European Union or HM Treasury (collectively, “Sanctions”).

The Corporation covenants and represents that neither it nor any of its affiliates, subsidiaries, directors or officers will use any payments made pursuant to the Indenture, (i) to fund or facilitate any activities of or business with any person who, at the time of such funding or facilitation, is the subject or target of Sanctions, (ii) to fund or facilitate any activities of or business with any country or territory that is the target or subject of Sanctions, or (iii) in any other manner that will result in a violation of Sanctions by any person.

IN WITNESS WHEREOF, each party hereto has caused this instrument to be signed in its name and behalf by its duly authorized officers, all as of the day and year first above written.

Regular Record Date: Close of business on the 15^th calendar day prior to the relevant Interest Payment Date

Issue Date: September 21, 2026

Maturity Date: March 30, 2057

Interest Payment Dates: Semi-annually on March 30 and September 30 of each year, commencing on March 30, 2027, in equal installments (except for the first interest payment, which will be $■ per $1,000 of the principal amount of Notes, payable on March 30, 2027 and representing interest accrued from and including September 21, 2026 to, but excluding, March 30, 2027), subject to deferral as described in Section 1.03B.) of the Second Supplemental Indenture.

Authorized Denomination: $2,000 or any integral multiple of $1,000 in excess thereof

Fortis Inc., a corporation duly continued and existing under the laws of the province of Newfoundland and Labrador, Canada (herein called the “Corporation,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & Co., or registered assigns, the principal sum of ■ ($■) (as revised by the Schedule of Increases and Decreases of Securities attached hereto) on the Maturity Date shown above and to pay interest thereon from the Issue Date shown above, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on each Interest Payment Date as specified above, subject to the Corporation’s Deferral Right, commencing on the date specified above and on the Maturity Date, at the applicable rate specified below, until the principal hereof is paid or made available for payment, and any principal, Additional Amounts and premium, and any such installment of interest, which is overdue shall bear interest at such rate (to the extent that the payment of such interest shall be legally enforceable), from the dates such amounts are due until they are paid or made available for payment, and such interest shall be payable on demand. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date (other than an Interest Payment Date that is the Maturity Date or a Redemption Date) will, as provided in the Indenture, be paid to the Person in whose name this 6.625% Fixed-to-Fixed Rate Junior Subordinated Note due 2057 (this “Security”) is registered at the close of business on the Regular Record Date as specified above (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the U.S. Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange, if any, on which the Securities of this series may be listed, and upon such notice as may be required by any such exchange, all as more fully provided in the Indenture.

This Security will bear interest from, and including, the Issue Date to, but excluding, March 30, 2032 at a rate of 6.625% per annum. From, and including, March 30, 2032 and every fifth anniversary of such date thereafter prior to the Maturity Date (each such date an “Interest Rate Reset Date”), the Security will bear interest at a rate per annum equal to the 5-Year Treasury Rate as of the most recent Interest Rate Calculation Date plus 2.016%; provided, that the interest rate during any Interest Rate Reset Period will not reset below 6.625% (which equals the initial interest rate on this Security).

Payments of interest on this Security will include interest accrued to but excluding the respective Interest Payment Dates. Interest payments for this Security shall be computed and paid on the basis of a 360-day year consisting of twelve 30-day months and will accrue from the Issue Date or from the most recent Interest Payment Date to which interest has been paid or duly provided for. In the event that any date on which interest is payable on this Security is not a Business Day, then payment of the interest payable on such date shall be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable.

So long as no Event of Default has occurred and is continuing, the Corporation may elect, in its sole discretion, at any date other than an Interest Payment Date, to defer the interest payable on the Security on one or more occasions for up to 10 consecutive years (a “Deferral Period”). There is no limit on the number of Deferral Periods that may occur under this Security. Such deferral will not constitute an Event of Default, a default or any other breach under the Security or the Indenture. Deferred Interest will accrue, compounding on each subsequent Interest Payment Date, until paid. A Deferral Period terminates on any Interest Payment Date where the Corporation pays all accrued and unpaid interest subject to such Deferral Period on such date. No Deferral Period may extend beyond the Maturity Date and, for greater certainty, all accrued and unpaid interest shall be due and payable on the Maturity Date.

Payment of the principal of, premium, if any, Additional Amounts, if any, and interest on this Security will be made at the office or agency of the Corporation maintained for that purpose, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. Payments of principal of, premium, if any, Additional Amounts, if any, and interest on the Securities of this series represented by a Global Security shall be made by wire transfer of immediately available funds to the Holder of such Global Security, provided that, in the case of payments of principal and premium, if any, such Global Security is first surrendered to the Paying Agent. If any of the Securities of this series are no longer represented by a Global Security, (i) payments of principal, premium, if any, and interest due at the Maturity Date or earlier redemption of such Securities shall be made at the office of the Paying Agent upon surrender of such Securities to the Paying Agent, and (ii) at the option of the Corporation payment of interest may be made by (A) check mailed to the address of the Person entitled thereto as such address shall appear in the Register or (B) wire transfer at such place and to such account at a banking institution in the United States as may be designated in writing to the Trustees at least five Business Days prior to the date for payment by the Person entitled thereto.

The Securities of this series shall not have a sinking fund.

This Security will be unsecured, subordinated obligations of the Corporation. The payment of principal, premium (if any) and interest on this Security, to the extent provided in the Indenture, will be subordinated in right of payment to the prior payment in full of all Senior Indebtedness.
