WHEREAS, the Company sponsors and maintains the Enbridge Supplemental Pension Plan, as amended and restated as of January 1, 2018 (as further amended) (the "Supplemental Plan"), for the benefit of its and its affiliates' eligible employees and their beneficiaries;

WHEREAS, pursuant to Section 1.9.01 of the Supplemental Plan, the Company has the authority to amend the Supplemental Plan through the execution of a certificate of amendment signed by an officer of the Company;

1.A new Section 1.1.05 is added after Section 1.1.04 as follows:

For former members of the WEI Plan and the Spectra Plans, service accrued prior to the date these individuals became Members of the El Plan is excluded from the calculation of the benefit payable under this Supplemental Plan (as that same service qualifies for benefit accrual under another supplemental pension plan sponsored by the Company or any of its affiliates)."
