Form of Enbridge Inc. 2019 Long Term Incentive Plan Restricted Stock Unit Grant Notice and Restricted Stock Unit Award Agreement

Pursuant to the Enbridge Inc. 2019 Long Term Incentive Plan (the “Plan”), Enbridge Inc. (the “Company”) has granted to the participant listed below (“Participant”) an award (the “Award”) of Restricted Stock Units (the “RSUs”), as described in this Restricted Stock Unit Grant Notice (this “Grant Notice”), subject to the terms and conditions of the Plan and the Restricted Stock Unit Award Agreement attached hereto as Exhibit A (the “Agreement”), both of which are incorporated into this Grant Notice by reference. Capitalized terms not specifically defined in this Grant Notice will have the meanings given to them in the Agreement, and if not defined in the Agreement, the meanings given to them in the Plan.

By Participant’s signature below, Participant agrees to be bound by the terms of this Grant Notice, the Plan and the Agreement, effective as of the Grant Date. Participant has reviewed the Plan, this Grant Notice and the Agreement in their entireties, and acknowledges that the Company hereby advises Participant to obtain the advice of counsel prior to executing this Grant Notice. Participant fully understands and accepts all provisions of the Plan, this Grant Notice and the Agreement (including, without limitation, the shareholder approval requirement set forth in Section 1.2 of the Agreement). Participant hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan, this Grant Notice or the Agreement. Participant agrees that the Grant Notice, the Agreement and the Plan constitute the entire agreement with respect to the Award.

1.1    Award of RSUs and Dividend Equivalents Units. (a) Subject to the terms and conditions of this Agreement (including, without limitation, the shareholder approval requirement set forth in Section 1.2) and the Plan, the Company has granted to Participant, effective as of the Grant Date set forth in the Grant Notice (the “Grant Date”), an award of RSUs as set forth in the Grant Notice. Each RSU represents the right to receive a cash amount equal to the Fair Market Value of one Share in accordance with Section 2.3; provided, however, that Participant will have no right to any payment until such time, if ever, that an RSU has vested and become payable hereunder.

(a)    In the event that any cash dividend is declared on Shares with a record date that occurs during the Dividend Equivalent Period (as defined below), the Participant will receive dividend equivalent rights in the form of additional RSUs (the “Dividend Equivalent Units”) at the time such dividend is paid to the Company’s shareholders. The number of Dividend Equivalent Units that the Participant will receive at any such time will be equal to (1) the cash dividend amount per Share times (2) the number of RSUs covered by the Participant’s Award (and, unless otherwise determined by the Company, any Dividend Equivalent Units previously credited under the Participant’s Award that have not been previously settled through the delivery of Shares (or cash) prior to, such date), divided by the Fair Market Value of one Share on the applicable dividend payment date; provided, that, in the event the Dividend Reinvestment Plan is then in effect, the number of Dividend Equivalent Units that the Participant will receive shall instead be calculated in accordance with the methodologies (including any discount feature) set forth therein, as determined by the Administrator in its sole discretion. Each Dividend Equivalent Unit will constitute an unfunded and unsecured promise of the Company to deliver (or cause to be delivered) one Share (or, cash equal to the Fair Market Value thereof) in accordance with the Plan, and will vest and be settled or paid at the same time, and subject to the same terms and conditions, as the RSUs on which such Dividend Equivalent Unit was accrued. “Dividend Equivalent Period” means the period commencing on the Grant Date and ending on the last day on which Shares (or cash) are delivered to the Participant with respect to the RSUs.

1.2    [Shareholder Approval Requirement. This Award will be contingent upon and effective as of approval of the Plan by the Company’s shareholders at the 2019 Annual Meeting. If the shareholders do not approve the Plan at the 2019 Annual Meeting, then this Agreement shall be null and void and the Participant shall have no rights or interests of any kind with respect to the RSUs or the associated Dividend Equivalent Units.]

1.3    Nature of Award. The RSUs granted to Participant pursuant to the Grant Notice and this Award are prospective in nature such that the Award is not in respect of service rendered in a year prior to the year that includes the Grant Date.

1.4    Incorporation of Terms of Plan. The RSUs are subject to the terms and conditions set forth in this Agreement and the Plan, which is incorporated herein by reference. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan will control.

1.5    Defined Terms. Capitalized terms not specifically defined in this Agreement will have the meanings specified in the Grant Notice or, if not defined in the Grant Notice, in the Plan.

1.6    Unsecured Promise. The RSUs will at all times prior to settlement represent an unsecured Company obligation payable only from the Company’s general assets.

2.1    Vesting; Maturity Date. (a) The RSUs will become vested on the Maturity Date; provided, that except as otherwise set forth in Section 2.1(b), the Participant is, as of the applicable Maturity Date, and has been at all times since the Grant Date, an Employee.

(a)    Accelerated Vesting.

(i)    CIC Termination. In the event that Participant has a Termination of Service within two years following a Change in Control as a result of (1) involuntary Termination of Service by the Company or a Subsidiary without Cause or (2) Termination of Service by the Participant for Good Reason (in each case, a “CIC Termination”), then all unvested RSUs shall automatically become 100% vested on the Participant’s Termination of Service and be settled in accordance with Section 2.3.

(ii)    Death or Disability. In the event that Participant has a Termination of Service due to the Participant’s death or Disability, then all unvested RSUs shall automatically become 100% vested on the Participant’s Termination of Service and be settled in accordance with Section 2.3.

(iii)    Retirement. In the event that Participant has a Termination of Service due to the Participant’s Retirement, then a pro rata portion of the unvested RSUs shall immediately vest on the Participant’s Termination of Service and be settled in accordance with Section 2.3. The pro rata portion of the RSUs that vest shall be calculated by multiplying the total number of RSUs granted by a fraction, the numerator of which is the number of full calendar days that have elapsed since the beginning of the Term through the date of the Participant’s Termination of Service and the denominator of which is the total number of full calendar days in the Term. Notwithstanding

the foregoing, if the Participant is eligible for Retirement at a time when the Participant incurs an involuntary Termination of Service without Cause, then Section 2.1(iv) shall apply and govern the vesting of the RSUs.

(iv)    Involuntary Termination Without Cause. In the event that Participant has a Termination of Service due to the Participant’s involuntary Termination of Service by the Company or a Subsidiary without Cause (other than a CIC Termination), then a pro rata portion of the unvested RSUs shall immediately vest on the Participant’s Termination of Service and be settled in accordance with Section 2.3. The pro rata portion of the RSUs that vest shall be calculated by multiplying the total number of RSUs granted by a fraction, the numerator of which is the number of full calendar days that have elapsed since the beginning of the Term through the date of the Participant’s Termination of Service (and, for these purposes, giving effect to any applicable Notice Period) and the denominator of which is the total number of full calendar days in the Term. For purposes of this Section 2.1(b)(iv), if a Participant’s employment terminates due to the constructive dismissal of the Participant or if a Participant ceases to be employed by a Subsidiary of the Company because such Participant’s employer ceases to be a Subsidiary of the Company, then such termination or cessation of employment shall be treated as an Termination of Service due to the Participant’s involuntary Termination without Cause.

2.2    Forfeiture and Leave of Absence. (a) Any RSUs that do not vest in accordance with Section 2.1 above shall immediately and automatically be cancelled and forfeited on the Participant’s Termination of Service for any reason. Notwithstanding anything herein to the contrary, in the event that Participant has an involuntary Termination of Service for Cause, then any RSUs that have not been settled in accordance with Section 2.3 as of the Participant’s Termination of Service, whether vested or not, shall be immediately forfeited as of the date of the Participant’s Termination of Service.

(a)    Notwithstanding anything in Section 2.1 to the contrary, in the event that the Participant was on Leave of Absence during the Term, the RSUs that vest pursuant to Section 2.1(a) shall be reduced on a pro-rata basis. The number of RSUs that shall be eligible to vest under Section 2.1(a) and settled under Section 2.3 shall be determined by multiplying the total number of RSUs granted by a fraction, the numerator of which is the number of full calendar days during the Term that the Participant was an Employee not on Leave of Absence and the denominator of which is the total number of full calendar days in the Term.

2.3    Settlement. (a) RSUs will be paid in cash within thirty days following the Maturity Date; provided, that in the case of RSUs that become vested due to Sections 2.1(b)(i) or 2.1(b)(ii), the Maturity Date shall be the date of the Participant’s Termination of Service and payment shall be made within thirty days thereafter, and provided further, that in no case will any payment in respect of an RSU be made after the third year following the year that includes the Grant Date.

(a)    The amount of cash paid with respect to the RSU will equal the Fair Market Value of a Share on the last trading day that immediately precedes the Maturity Date and will be

paid in the currency of Canada or the United States, depending on the applicable jurisdiction in which the Participant resides. For purposes of this Section 2.3, “Fair Market Value” shall mean, as of a particular day, the weighted average of the board lot trading prices per Share on the Toronto Stock Exchange, or the New York Stock Exchange, for the last twenty trading days immediately prior to such day.

2.4    No Rights as Shareholder. Participant will have no rights as a shareholder (including, without limitation, the right to vote and to receive dividends) with respect to any RSUs covered by this Agreement.

3.1    Tax Withholding. (a) Participant must make arrangements acceptable to the Administrator for the satisfaction of any non-U.S., U.S.-federal, U.S.-state, or local income and employment tax withholding obligations arising in connection with the Award.

(a)    Participant acknowledges that Participant is ultimately liable and responsible for all taxes owed in connection with the RSUs, regardless of any action the Company or any Subsidiary takes with respect to any tax withholding obligations that arise in connection with the RSUs. Neither the Company nor any Subsidiary makes any representation or undertaking regarding the treatment of any tax withholding in connection with the awarding, vesting or payment of the RSUs. The Company and the Subsidiaries do not commit to, and are under no obligation to structure this Award to, reduce or eliminate Participant’s tax liability.

(b)    Participant acknowledges that the Company has advised Participant to obtain independent legal and tax advice regarding the grant and payment in respect of the RSUs.

3.2    Section 409A. The provisions of this Section 3.2 apply to the Participant only if the Participant is a US taxpayer. This Agreement and the Plan provisions that apply to the RSUs are intended and will be construed to comply with Section 409A (including the requirements applicable to, or the conditions for exemption from treatment as, “deferred compensation” as defined in the regulations under Section 409A, whether by reason of short-term deferral treatment or other exceptions or provisions). The Administrator will have full authority to give effect to this intent. To the extent that any portion of the RSUs are intended to satisfy the requirements for short-term deferral treatment under Section 409A, delivery for such portion will occur by the March 15 coinciding with the last day of the applicable “short-term deferral” period described in Reg. 1.409A-1(b)(4) in order for the payment in respect of such RSUs to be within the short-term deferral exception unless, in order to permit all applicable conditions or restrictions on delivery to be satisfied, the Administrator elects, pursuant to Reg. 1.409A-1(b)(4)(i)(D) or otherwise as may be permitted in accordance with Section 409A, to delay payment to a later date within the same calendar year or to such later date as may be permitted under Section 409A. For the avoidance of doubt, if RSUs include a “series of installment payments” as described in Reg. 1.409A-2(b)

4.1    Adjustments. Participant acknowledges that the RSUs are subject to adjustment, modification and termination in certain events as provided in this Agreement and the Plan.

4.2    Limited Transferability. The Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution.

4.3    Conformity to Applicable Laws. Participant acknowledges that the Plan, the Grant Notice and this Agreement are intended to conform to the extent necessary with all Applicable Laws and, to the extent Applicable Laws permit, will be deemed to be amended to the minimum extent necessary to conform to Applicable Laws. Any determination in this regard that is made by the Administrator will be final, binding, and conclusive on all interested persons. The obligations of the Company and the rights of Participant are subject to compliance with all Applicable Laws.

Notwithstanding any other provision of the Plan or this Agreement, if Participant is subject to Section 16 of the Exchange Act, the Plan, the Grant Notice, this Agreement, the RSUs will be subject to any additional limitations set forth in any applicable exemptive rule under Section 16 of the Exchange Act (including any amendment to Rule 16b-3) that are requirements for the application of such exemptive rule. To the extent Applicable Laws permit, this Agreement will be deemed amended as necessary to conform to such applicable exemptive rule.
