	(a)
	the surviving or resulting entity remains a publicly traded entity and agrees to assume the obligations of AltaGas and its Affiliates under AltaGas’ Phantom Unit Plan and this Plan, in all material respects, including in respect of all Outstanding Phantom Units, to the satisfaction of the board of directors of AltaGas (as constituted prior to the Change of Control), and such board, in its sole discretion, determines that:


		
	(i)

	(ii)
	the Benchmark Security of such surviving or resulting entity will not be substantially similar to the Benchmark Security used immediately prior to the Change of Control for purposes of assessing the satisfaction of performance measures on outstanding RUs and PUs, then the Plan shall continue in force and effect in an appropriate manner and with appropriate amendments, as determined at the sole discretion of the board of directors of AltaGas (as constituted prior to the Change of Control), with the Change of Control Value calculated on the Change of Control and payable on the original Vesting Date(s), provided that the Participant continues to be an eligible Participant on such Vesting Date(s) unless otherwise specified in the Agreement. In the event of a Retirement, or the Permanent Disability or death of a Participant prior to the original Vesting Date(s), the Change of Control Value may be pro-rated to the date of such event or otherwise treated in a manner consistent with the intent of Section 6(c), (d) or (e), as applicable. The Board, with the consent of the board of directors of AltaGas, shall have the power to amend the Plan and Agreements to permit the actions described in this subsection without the consent of any Participant.

Payments made in accordance with this Section shall be subject to Sections 16 and 17.
		
	8.
	Effect of Certain Corporate Changes


		
	(a)
	Effect of Reorganization.  Upon the occurrence of a Reorganization Event:


		
	(i)
	to which the Company is a party or upon the making of any proposal by the board of directors of AltaGas that AltaGas enter into a Reorganization Event to which the Company is a party, then the board of directors of AltaGas shall cause the surviving entity or new owner, as the case may be, to agree to adopt the Plan and to maintain it, with respect to all grants outstanding under the Plan as of the date of the Reorganization Event, in accordance with the terms in effect as of such date, and to agree to adopt the Agreements and to continue in effect their respective terms as such terms were in effect as of the date of the Reorganization Event; or


		
	(ii)
	to which the Company is not a party or upon the making of any proposal by the board of directors of AltaGas that AltaGas enter into a Reorganization Event to which the Company is not a party, then the respective terms of the Plan and the Agreements will continue in effect as such terms were in effect as of the date of the Reorganization Event.


In either case, the Plan and related Agreements may be modified by the Board, as constituted prior to the Reorganization Event, without the consent of any Participant, to utilize the securities of such surviving entity or new owner or such other publicly traded security which most closely tracks the value of the business of AltaGas, a surviving entity or new owner, as appropriate, in lieu of the Benchmark Security, to measure the Unit Value and, on a going forward basis, the Distribution Amounts.
		
	(b)
	Material Impediment.  Notwithstanding the provisions of subsection (a), in the event that the effect of the provisions contained in subsection (a) should become, in the Board’s sole discretion, a material impediment, either from a financial point of view or otherwise, to the consummation of a proposed Reorganization Event, the Board with the consent of the board of directors of AltaGas may take such action as it deems equitable and appropriate to provide each Participant with a benefit equivalent to that to which he or she would have been entitled had such event not occurred, which may include, without limitation, amending any outstanding Agreement without the consent of the Participant.  


		
	(c)
	Conditional Action.  Any action taken by the Board may be made conditional upon the consummation of the applicable Reorganization Event. 


		
	(d)
	Other Corporate Restructuring.  Further, in the event that a division or Affiliate of AltaGas is acquired by another Person (other than an Affiliate), or the Company or AltaGas is reorganized, dissolved or liquidated, or an event or series of events involving a corporate restructuring not described in the definition of Reorganization Event occurs other than with an Affiliate, or the Board shall propose that the Company enter into any such transaction, event or series of events, then the Board with the consent of the board of directors of AltaGas may take such action as it deems equitable and appropriate to provide each Participant with a benefit equivalent to that to which he or she would have been entitled had such event not occurred, which may include, without limitation, amending any outstanding Agreement without the consent of the Participant.  


		
	(e)
	Dilution and Other Adjustments.  In the event of a split, issuance or repurchase of shares, units or securities convertible into or exchangeable for shares or units, grants of options, warrants or rights to purchase shares or units, recapitalization, combination, exchange or similar change affecting the Benchmark Security, the Board with the consent of the board of directors of AltaGas shall make either or both of the following adjustments as it deems equitable and appropriate to provide each Participant with a benefit equivalent to that to which he or she would have been entitled had such event not occurred: 


		
	(i)
	adjust the number of Phantom Units granted to each Participant; and


		
	(ii)
	make any other adjustments or take such action as the Board deems appropriate, which may include, without limitation, amending any outstanding Agreement without the consent of the Participant. 


Such adjustments shall be conclusive and binding for all purposes.
		
	9.
	Unfunded Plan


The general funds of the Company shall be the sole source for payment of Vesting Amounts under the Plan, and the Company shall not have any obligation to establish any separate fund or trust or other segregation of assets to provide for payments under the Plan. Nothing contained in the Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind, or a fiduciary relationship, between the Company and a Participant or any other person.  To the extent any Person acquires any rights to receive payments hereunder from the Company, such rights shall be no greater than those of an unsecured creditor.
		
	10.
	No Rights to Grants or Continued Employment or Independent Contract  


No director, officer, employee or independent contractor shall have any claim or right to receive grants of Phantom Units under the Plan. Neither the Plan nor any action taken hereunder shall be construed as giving any director, officer, employee or independent contractor any right to be retained by the Company, nor does it restrict in any way the right of the Company, as the case may be, to terminate an employee’s employment or service, director’s services, or independent contractor’s contract at any time.
		
	11.
	No Representation as to Value 


Neither AltaGas or the Company, nor any Affiliate makes any representation, warranty or guarantee as to the future value of a Phantom Unit or as to the future value of any Participant’s Vesting Amount.  No amount will be paid to, or in respect of, a Participant under the Plan to compensate for a downward fluctuation in the price of the Benchmark Securities nor will any other form of benefit be conferred upon, or in respect of, a Participant for such purpose.
		
	12.
	Securityholder Rights 


No grant of Phantom Units under the Plan shall entitle a Participant or Beneficiary to any rights of a holder of the Benchmark Security and under no circumstances are Phantom Units to be considered Benchmark Securities.
		
	13.
	General Restrictions and Assignment


Except as required by law, the rights of a Participant under the Plan are not capable of being anticipated, assigned, transferred, alienated, sold, encumbered, pledged, mortgaged or charged and are not capable of being subject to attachment or legal process for the payment of any debts or obligations of the Participant.
		
	14.
	Clawback


The Clawback Policy shall apply to any Phantom Units granted under the Plan.
		
	15.
	No Restriction on Right of AltaGas to Effect Corporate Changes 


The Plan shall not affect in any way the right or power of AltaGas or its shareholders to make or authorize any adjustment, recapitalization, reorganization or other change in the capital structure of AltaGas or its business, or any amalgamation, combination, merger or consolidation of AltaGas, or any issue of shares, units, options, warrants or rights to purchase shares, units, bonds, debentures, preferred or prior preference shares whose rights are superior to or affect the Benchmark Security or the rights thereof or which are convertible into or exchangeable for the Benchmark Security, or the dissolution or liquidation of AltaGas, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.
		
	16.
	Tax Treatment and Tax Withholding 


The Company makes no representation or warranty with respect to the income tax treatment to be accorded any Participant with respect to any grant of Phantom Units or the receipt by any Participant of the Vesting Amount or securities therefor.  The Company recommends that each Participant obtain independent tax advice regarding these matters.
The Company or an Affiliate thereof, as appropriate, may deduct or withhold, or require the Participant or the Participant’s Beneficiary to remit to the Company or its Affiliate, an amount sufficient to satisfy federal, state, and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to any taxable event arising as a result of an award of Phantom Units.
		
	17.
	Section 409A


It is intended that, to the extent Phantom Units constitute deferred compensation subject to Section 409A, the provisions of the Plan comply with Section 409A, and all provisions of the Plan shall be construed and interpreted in a manner consistent with the requirements for avoiding taxes or penalties under Section 409A.  With respect to a Phantom Unit granted to a Participant who is subject to the income tax laws of the United States of America, the following provisions shall apply: 
		
	(a)
	A Vesting Amount with respect to such Phantom Unit that is payable upon such Participant’s termination of employment shall only be so paid if such termination of employment constitutes a "separation from service" under Section 409A.  If such Participant is a “specified employee” under Section 409A at the time of his or her termination of employment, such Vesting Amount shall not be paid before the date which is six months after the date of the Participant’s separation from service (or, if earlier, the date of the Participant’s death) to the extent necessary to avoid penalties under Section 409A.  Any payments that would otherwise be made during this period of delay shall be accumulated and paid on the first day of the seventh month after the date of the Participant’s separation from service (or, if earlier, the first day of the month after the Participant’s death). 


		
	(b)
	A Vesting Amount with respect to such Phantom Unit that is payable in connection with a Change of Control, shall only be so paid if such Change of Control constitutes a "change in control event" under Section 409A.


		
	(c)
	Any adjustments made pursuant to Section 8 shall: (i) for Phantom Units that are subject to Section 409A, be consistent with the requirements of Section 409A, and (ii) in the case of any Phantom Units that are exempt from Section 409A under the short-term deferral exception, be made so as to preserve the applicability of the short-term deferral exception.


		
	18.
	Plan Amendment and Termination 


The Board, with the consent of the board of directors of AltaGas, may at any time and from time to time alter, amend, suspend or terminate the Plan in whole or in part. No termination or amendment of the Plan may materially adversely affect the rights of any Participant to whom any Phantom Units shall previously have been granted without the consent of such Participant unless, in the case of an amendment, it is required to comply with applicable laws, regulations, rules, orders of governmental or regulatory authorities or the requirements of any stock exchange on which common shares of AltaGas are listed.  No grants may become effective under the Plan after the date of termination.  Subject to the provisions and within the limitations of the Plan, the Board may amend the terms of any Outstanding Phantom Unit and related Agreement.  
		
	19.
	Severability  


If any provision of the Plan is declared invalid, illegal or unenforceable in any respect or contravenes any order, policy, by-law or regulation of any regulatory body or securities exchange having jurisdiction or authority over AltaGas, the Company or the Plan, the remaining provisions of the Plan shall be unimpaired, and the invalid, illegal, unenforceable or contravening provision shall be replaced by a valid, legal, enforceable and compliant provision of similar economic intent and effect.
		
	20.
