ARTICLE 2

THE NOTES

2.1            No Limitation on Issue

The aggregate principal amount of the Notes that may be issued and authenticated hereunder shall be unlimited.

2.2            Terms of Notes

2.2.1          The Notes shall be dated as of the Closing Date, regardless of their actual date of issue, and shall mature on the Maturity Date.

2.2.2          The Notes will bear interest (i) from, and including, the Closing Date to, but not including, the Initial Interest Reset Date at the rate of 7.375% per annum and (ii) from and including the Initial Interest Reset Date, during each Interest Reset Period, at a rate per annum equal to the Five-Year Treasury Rate as of the most recent Reset Interest Determination Date, plus 3.122%, to be reset on each Interest Reset Date. Interest on the Notes will be payable semi-annually in arrears on each Interest Payment Date, commencing on September 15, 2024, subject to deferral as set forth in Article 5. The applicable interest rate for each Interest Reset Period will be determined by the Calculation Agent as of the applicable Reset Interest Determination Date. Subject to Article 5, interest as aforesaid shall be payable after as well as before default, with interest on overdue interest, in like money, at the same rates and on the same dates.

2.2.3          Interest on the Notes will be calculated on the basis of a 360-day year consisting of twelve 30-day months and, for any period shorter than six months, on the basis of the actual number of days elapsed per 30-day month. For the purposes of disclosure under the Interest Act (Canada), and without affecting the interest payable on the Notes, whenever the interest rate on the Notes is to be calculated on the basis of a period of less than a calendar year, the yearly interest rate equivalent for such interest rate will be the interest rate multiplied by the actual number of days in the relevant calendar year and divided by the number of days used in calculating the specified interest rate.

2.2.4         If any Interest Payment Date falls on a day that is not a Business Day, the payment of interest, principal or premium due on such Interest Payment Date will be postponed until the next Business Day, and no further interest or other sums will accrue in respect of such postponement.

2.2.5          Interest payments will be made to Holders in whose names the Notes are registered at the close of business on March 1 and September 1 (in each case, whether or not a Business Day), as the case may be, immediately preceding the relevant Interest Payment Date.

-5-

2.3            Form of Notes

2.3.1          The Notes shall be issued only as fully registered Notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

2.3.2          The Notes and the certificate of authentication of the Trustee endorsed thereon shall be in the English language and shall be substantially in the form set out in Schedule A hereto, with such appropriate additions, deletions, substitutions and variations as the Trustee may approve and shall bear such distinguishing letters and numbers as the Trustee may approve, such approval of the Trustee to be conclusively evidenced by its authentication of the Notes.

2.3.3          The Notes may be engraved, printed or lithographed, or partly in one form and partly in another, as the Company may determine.

2.4            Calculation Agent

2.4.1          Unless all of the outstanding Notes are to be redeemed or have been redeemed as of the Initial Interest Reset Date, the Company shall appoint a Calculation Agent with respect to the Notes prior to the Reset Interest Determination Date preceding the Initial Interest Reset Date.

2.4.2          The Calculation Agent will determine the applicable interest rate for each Interest Reset Period as of the applicable Reset Interest Determination Date. Promptly upon such determination, the Calculation Agent, if other than the Company or an Affiliate of the Company, will notify the Company of the interest rate for the relevant Interest Reset Period and the Company will then promptly notify the Trustee, if other than the Calculation Agent, of such interest rate.

2.4.3          The Calculation Agent’s determination of any interest rate, and its calculation of the amount of interest for any Interest Reset Period beginning on or after the Initial Interest Reset Date: (i) will be on file at the Company’s principal offices, (ii) will be made available to any Holder upon request, (iii) will be conclusive and binding absent manifest error, (iv) may be made in the Calculation Agent’s sole discretion and (v) notwithstanding anything to the contrary in the documentation relating to the Notes, will become effective without consent from any other person or entity.

2.5            Additional Amounts

2.5.1          The Company will, subject to the exceptions and limitations set forth below, pay to any Holder of the Notes who is a non-resident of Canada for purposes of the Income Tax Act (Canada) and the regulations thereunder (collectively, the “Tax Act”) such additional amounts (“Additional Amounts”) as may be necessary so that every net payment on the Notes held by such Holder of the Notes, after deduction or withholding by the Company or any of its paying agents for or on account of any present or future tax, assessment or other governmental charge (including penalties, interest and other liabilities related thereto) imposed by the government of Canada (or any political subdivision or taxing authority thereof or therein) upon or as a result of such payment, will not be less than the amount provided in those Notes to be then due and payable (and the Company will remit the full amount withheld to the relevant authority in accordance with applicable law).

(c)             for or on account of any tax, assessment or other governmental charge which would not have been so imposed but for: (i) the presentation by the holder of those Notes on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later; or (ii) the holder’s failure to comply with any certification, identification, information, 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, any such taxes, assessment or charge;

(f)              for or on account of any tax, assessment or other governmental charge which is payable otherwise than by withholding from a payment on those Notes;

(g)            any withholding or deduction imposed pursuant to: (i) Sections 1471 to 1474 of the U.S. Internal Revenue Code of 1986, as amended (“FATCA”), or any successor version thereof, or any similar legislation imposed by any other governmental authority, (ii) any treaty, law, regulation or other official guidance enacted by Canada implementing FATCA or an intergovernmental agreement with respect to FATCA or any similar legislation imposed by any other governmental authority, or (iii) any agreement between the Company and the United States or any authority thereof implementing FATCA; or

nor will Additional Amounts be paid with respect to any payment on those Notes to a Holder of the Notes who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of Canada (or any political subdivision thereof) to be included in the income for Canadian federal income tax purposes of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to payment of the Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of such Notes.

7.4.1          Nothing contained in this Article or elsewhere in this Indenture or in the Notes is intended to or shall impair, as among the Company, its creditors other than the holders of Senior Indebtedness and the Holders, the obligation of the Company, which is absolute and unconditional, to pay to the Holders the principal of and interest on the Notes as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders and creditors of the Company other than the holders of Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or any Holder from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article of the holders of Senior Indebtedness in respect of cash, property or securities of the Company received upon the exercise of any such remedy.

-12-

7.4.2          Upon payment or distribution of assets of the Company referred to in this Article, the Trustee and the Holders shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which any such dissolution, winding up, liquidation or reorganization proceeding affecting the affairs of the Company is pending or upon a certificate of the trustee in bankruptcy, receiver, receiver and manager, assignee for the benefit of creditors, liquidating trustee or agent or other person making any payment or distribution, delivered to the Trustee or to the Holders, for the purpose of ascertaining the persons entitled to participate in such payment or distribution, the holders of the Senior Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount paid or distributed thereon and all other facts pertinent thereto or to this Article.

7.5            Payments on Notes Permitted

Nothing contained in this Article or elsewhere in this Indenture or in the Notes shall affect the obligations of the Company to make, or prevent the Company from making, payment of the principal of or interest on the Notes in accordance with the provisions hereof and thereof, except as otherwise provided in this Article.

7.6            Effectuation of Subordination by Trustee

Each Holder by its acceptance thereof authorizes and directs the Trustee on its behalf to take such action as may be necessary or appropriate to effect the subordination as provided in this Article and appoints the Trustee as its attorney-in-fact for any and all such purposes. This appointment shall be irrevocable. Upon request of the Company, and upon being furnished a certificate of the Company stating that one or more named Persons are Senior Creditors and specifying the amount and nature of the Senior Indebtedness of such Senior Creditor, the Trustee shall enter into a written agreement or agreements with the Company and the Persons named in such certificate of the Company providing that such Persons are entitled to all the rights and benefits of this Article as Senior Creditors and for such other matters, such as an agreement not to amend the provisions of this Article and the definitions used herein without the consent of such Senior Creditors, as the Senior Creditors may reasonably request. Such agreement shall be conclusive evidence that the indebtedness specified therein is Senior Indebtedness; however, nothing herein shall impair the rights of any Senior Creditor who has not entered into such an agreement.

-13-

7.7            Knowledge of Trustee

Notwithstanding the provisions of this Article or any other provisions of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment of moneys to or by the Trustee, or the taking of any other action by the Trustee, unless and until the Trustee shall have received written notice thereof mailed or delivered to the Trustee from the Company, any Holder, any paying agent or the holder or representative of any class of Senior Indebtedness; provided that if at least three Business Days prior to the date upon which by the terms hereof any such moneys may become payable for any purpose (including, without limitation, the payment of the principal of or interest on any Note) the Trustee shall not have received with respect to such moneys the notice provided for in this Section, then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such moneys and to apply the same to the purpose for which they were received and shall not be affected by any notice to the contrary that may be received by it within three Business Days prior to or on or after such date.

7.8            Trustee May Hold Senior Indebtedness

The Trustee shall be entitled to all the rights set forth in this Article with respect to any Senior Indebtedness at the time held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder.

7.9            Rights of Holders of Senior Indebtedness Not Impaired

7.9.1          No right of any present or future holder of any Senior Indebtedness to enforce the subordination herein shall at any time or in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with.

7.9.2          With respect to the holders of Senior Indebtedness, (i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture, (ii) the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture, (iii) no implied covenants or obligations shall be read into this Indenture against the Trustee and (iv) the Trustee shall not be deemed to be a fiduciary as to such holders.

7.10          Article Applicable to Paying Agents

In case at any time any paying agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article shall in such case (unless the context shall require otherwise) be construed as extending to and including such paying agent within its meaning as fully for all intents and purposes as if such paying agent were named in this Article in addition to or in place of the Trustee; provided, however, that Sections 7.7 and 7.8 shall not apply to the Company if it acts as its own paying agent.

7.11          Trustee; Compensation Not Prejudiced

Nothing in this Article shall apply to claims of, or payments to, the Trustee pursuant to Section 607 of the Indenture.

(i) default in the payment of any interest upon the Notes when it becomes due and payable, and continuance of such default for a period of 30 days (subject to the Company’s right, in its sole discretion, to defer interest payments as provided in Article 5 of this Thirteenth Supplemental Indenture);

(iv) the Company defaults in the performance of, or breaches, any other covenant or warranty in the Indenture, which default or breach continues uncured for a period of 60 days after the Company receives written notice from the Trustee or the Company and the Trustee receive written notice from the Holders of not less than one-quarter of the principal amount of Notes then outstanding.

If an Event of Default has occurred and is continuing, then the Company shall be deemed to be in default under the Indenture and the Notes and the Trustee may, in its discretion and shall upon the request of holders of not less than one-quarter of the principal amount of Notes then outstanding under the Indenture, demand payment of the principal or premium, if any, together with any accrued and unpaid interest up to (but excluding) such date, which shall immediately become due and payable in cash, and may institute legal proceedings for the collection of such aggregate amount in the event the Company fails to make payment thereof upon such demand.

ISIN: US29250NCG88

ENBRIDGE INC. (the “Company”) for value received hereby promises to pay to the registered holder hereof (the “Holder”) on March 15, 2055 or on such earlier date as the principal amount hereof may become due in accordance with the provisions of the Indenture hereinafter mentioned, the principal sum of

[●] DOLLARS

$[●]

A-1

in lawful money of the United States on presentation and surrender of this Note (as defined below) at the principal office of the Trustee in The City of New York, New York or such other location as it may designate from time to time, and to pay interest on the principal amount hereof from and including the date hereof, or from and including the last Interest Payment Date (as defined in the Indenture) to which interest shall have been paid or made available for payment on the outstanding Notes, whichever is later, semi-annually in arrears on March 15 and September 15 of each year (i) from, and including, the date hereof to, but not including, March 15, 2030 at the rate of 7.375% per annum and (ii) from, and including, March 15, 2030, during each Interest Reset Period (as defined in the Indenture), at a rate per annum equal to the Five-Year Treasury Rate (as defined in the Indenture) as of the most recent Reset Interest Determination Date (as defined in the Indenture), plus 3.122%, to be reset on each Interest Reset Date. Subject to Article 5 of the Thirteenth Supplemental Indenture referred to below, interest as aforesaid shall be payable after as well as before default, with interest on overdue interest at the same rates and on the same dates.

This Note is one of the 7.375% Fixed-to-Fixed Rate Subordinated Notes due 2055 (the “Notes”) of the Company issued or issuable under the provisions of an Indenture, dated as of February 25, 2005, between the Company and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”), as amended and supplemented by a First Supplemental Indenture, dated as of March 1, 2012, an Eighth Supplemental Indenture, dated as of June 28, 2021, and a Thirteenth Supplemental Indenture, dated as of June 27, 2024, in each case, between the Company and the Trustee (which indenture as amended and supplemented is herein referred to as the “Indenture”). The Notes issuable under the Indenture are unlimited in principal amount. Reference is hereby expressly made to the Indenture for a description of the terms and conditions upon which the Notes are or are to be issued and held and the rights, remedies and obligations of the holders of the Notes, of the Company and of the Trustee in respect thereof, all to the same effect as if the provisions of the Indenture were herein set forth, to all of which provisions the Holder by acceptance hereof acknowledges and assents.

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

The Notes are issuable only as fully registered Notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. Upon compliance with the provisions of the Indenture, the Notes of any denomination may be exchanged for an equal aggregate principal amount of the Notes in any other authorized denomination or denominations.

The Notes are direct obligations of the Company but are not secured by any mortgage, pledge, hypothec or other charge.

The indebtedness evidenced by this Note and by all other Notes now or hereafter authenticated and delivered under the Indenture is subordinated and subject in right of payment, to the extent and in the manner provided in the Indenture, to the prior payment in full of all present and future Senior Indebtedness (as defined in the Indenture), whether outstanding at the date of the Indenture or thereafter created, incurred, assumed or guaranteed.

A-2

The right is reserved to the Company to purchase or redeem the Notes for cancellation, in all cases in accordance with the provisions of the Indenture.

This Note may only be transferred, upon compliance with the conditions prescribed in the Indenture, in one of the registers to be kept at the principal office of the Trustee or other registrar in The City of New York, New York by the Holder or such Holder’s executors or administrators or other legal representatives or such Holder’s attorney duly appointed by an instrument in form and substance satisfactory to the Trustee or other registrar, and upon compliance with such reasonable requirements as the Trustee and/or other registrar may prescribe.

This Note shall be governed by and construed in accordance with the laws of the State of New York, except for the subordination provisions referred to herein and in the Thirteenth Supplemental Indenture, dated as of June 27, 2024, which are governed by, and construed in accordance with, the laws of the Province of Alberta.

This Note shall not become obligatory for any purpose until it shall have been authenticated by the Trustee under the Indenture.
