WHEREAS, the Resolutions authorize any two officers of the Corporation or an Affiliate thereof, to take any action that they deem to be necessary or desirable to effectuate the transaction described in the SPA; and

WHEREAS, Section 6.l0(e) of the SPA requires that (i) Saint Lawrence Gas Company, Inc. ("SLG") and any other applicable subsidiary affiliate of SLG cease to be participating employers in the Plan, (ii) the employees and former employees of SLG and its subsidiary affiliates who, immediately prior to the closing of the transaction contemplated in the SPA, have an accrued benefit under the Plan (the "SLG Participants") shall cease participation in the Plan, and (iii) all of the liabilities of the SLG Participants under the Plan shall be assumed by the Buyer or the Affiliate of Buyer, as defined in the SPA.

NOW, THEREFORE, the Plan is hereby amended, effective as of the Effective Date, as follows:

(t) "Participating Affiliate" means (i) the Company, (ii) Spectra Energy Corp, (iii) Spectra Energy Operating Company LLC, and (iv) PanEnergy Service, Limited Partnership. As of the SLG Closing, St. Lawrence Gas Company, Inc. has ceased to be a Participating Affiliate.

(qq)     "SLG SPA" means the Securities Purchase Agreement between Enbridge Gas Distribution Inc. and Liberty Utilities Co. dated August 31, 2017, and as it may be amended.

Effective as of the SLG Closing, St. Lawrence Gas Company, Inc. shall cease to be an Affiliate. In addition, pursuant to the SLG SPA, effective as of the SLG Closing:

(1)St. Lawrence Gas Company, Inc. shall cease to be a Participating Affiliate; and

(2)St. Lawrence Gas Participants shall cease to be Plan Participants and thus shall not be entitled to receive any benefit payable under the Plan; and

(3)The liabilities of this Plan relating to the St. Lawrence Gas Participants shall be transferred to the SLG Buyer Supplemental Plan on or after the date of the SLG Closing and all of their benefits shall be fully provided under the SLG Buyer Supplemental Plan and not this Plan.
