An account, to be known as a “Deferred Stock Unit Account”, shall be maintained by the Corporation for each Participant and will show the number of Deferred Stock Units credited to a Participant, to six (6) decimal places, from time to time.

In respect of any amount of STIP Payment payable to a Participant in Deferred Stock Units in accordance with the election percentage set out in Subsection 5(d), the number of Deferred Stock Units to be credited to that Participant will be calculated by dividing the dollar amount of the STIP Payment payable to that Participant on the STIP Payment Date by the Market Value on the Trading Day immediately preceding such date.

In addition to Subsection 5(b), whenever any cash dividend or other cash distribution is paid on the Shares, additional Deferred Stock Units will be credited to the Participant’s Deferred Stock Unit Account. The number of such additional Deferred Stock Units will be calculated by dividing the aggregate dividends that would have been paid to such Participant if the Deferred Stock Units in the Participant’s Deferred Stock Unit Account had been Shares, by the Market Value of a Share on the date on which the dividends are paid on the Shares, or such other methodology determined by the Administrator.

Each employee eligible to participate in the Plan pursuant to Section 4 may become a Participant by delivering to the Corporation a completed Election

Except as provided in Subsection 5(i), the determined value of all Deferred Stock Units credited to the Deferred Stock Unit Account, net of required withholdings, shall be paid to a Participant in one or two lump sum cash payments and on a date or dates to be agreed upon by that Participant and the Corporation, provided that the payment date(s) must occur subsequent to the Retirement Date and no later than December 15 of the first calendar year commencing after that Retirement Date.

If no such payment date agreement is reached pursuant to Subsection 5(g), the payment date will be December 15 of the first calendar year commencing after that Participant’s Retirement Date.

When a Participant dies, the determined value of all Deferred Stock Units credited to that Participant’s Deferred Stock Unit Account, net of applicable withholdings, shall be paid in one lump sum cash payment to the Participant’s Beneficiary as soon as practicable after the Participant’s death, provided that the payment date must occur subsequent to the Retirement Date and no later than December 15 of the first calendar year commencing after that Retirement Date.

To determine the value of Deferred Stock Units for the purposes of a payment to a Participant, a Deferred Stock Unit will be valued equal to the Market Value on the Trading Day immediately preceding the Retirement Date multiplied by the number of Deferred Stock Units (including fractional Units) credited to a Participant’s Deferred Stock Unit Account.

Should the Shares not be publicly traded on The Toronto Stock Exchange at the relevant time such that the Market Value cannot be determined in accordance with the formulae set out in the definitions of that term, such value shall be determined by the Board acting in good faith.

In the event of any merger, consolidation or other reorganization of the Corporation in which the Corporation is not the surviving or continuing corporation, all Deferred Stock Units granted hereunder and outstanding on the date of such reorganization shall be assumed by the surviving or continuing corporation.

The rights and interests of a Participant under this Plan, including the Deferred Stock Units, shall not be assignable or transferable, otherwise than in case of death as set out in Subsection 5(i).

and the Corporation, its employees and agents shall bear no liability in connection with the payment of such taxes or the compliance with such disclosure requirements, if any.

No such amendment shall be considered prejudicial to any interest of a Participant or a Beneficiary in the Plan.

In the event of a conflict between the terms of this Plan and the terms of any written employment agreement between a Participant and the Corporation, the terms of the written employment agreement shall prevail.

All awards and payments under this Plan will be subject to any claw-back policy of the Corporation, including the Incentive Compensation Clawback Policy, the Enbridge Inc. Clawback Policy for the Mandatory Recovery of Erroneously Awarded Incentive-Based Compensation, and any other claw-back policy adopted to comply with Applicable Laws (as defined below) (including the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder) that the Corporation may adopt from time to time to the extent set forth in such claw-back policy and in accordance with such policy, may be subject to the requirement that the payments under this Plan (including any proceeds, gains or other economic benefit the Participant actually or constructively receives upon receipt of any payment under this Plan) be repaid to the Corporation after they have been paid or distributed to the Participant. For the purpose of this Section, “Applicable Laws” means the requirements relating to the administration of incentive plans under Canada and United States federal, provincial and state securities, tax and other applicable laws, rules and regulations, the applicable rules of any stock exchange or quotation system on which the common shares of the Corporation are listed or quoted and the applicable laws and rules of any foreign country or other jurisdiction where payments under this Plan are made.

If there is a change in the issued and outstanding Shares of the Corporation by reason of any stock dividend, stock split, consolidation, recapitalization, amalgamation, reorganization, arrangement or other transaction, the HRC Committee may make appropriate adjustments to the number or kind of shares or securities of the Corporation upon which Deferred Stock Units are based under this Plan, and as regards to Deferred Stock Units previously granted or to be granted pursuant to this Plan, in the number or kind of shares or securities of the Corporation upon which Deferred Stock Units are based.

Except where expressly provided otherwise all references in the Plan to currency refer to lawful Canadian currency.

This Plan is created under and is to be governed, construed and administered in accordance with the laws of the Province of Alberta and the laws of Canada applicable therein.

The Board may, in its sole discretion and without the consent of any Participant, terminate the Plan at any time by giving written notice thereof to each Participant. Following termination of the Plan, additional Deferred Stock Units shall not be credited to Deferred Stock Unit Accounts of Participants. Notwithstanding the termination of the Plan, all amounts distributable under the Plan shall be paid to the persons entitled thereto on the date on which such distributions would have been made had the Plan not been terminated.

This Plan is effective as of November 1, 2025, and may be amended from time to time.

This Appendix A, and the Plan as it relates to US Taxpayers, shall be interpreted and applied in a manner that complies with the requirements of Section 409A of the Code and paragraph 6801(d) of the Income Tax Regulations (Canada).

As used herein for purposes of Appendix A, the following terms shall have the following meanings, respectively:

“Separation from Service” has the meaning set forth in Section 409A(a)(2)(A)(i) of the Code and Treas. Reg. Section 1.409A-1(h).
