1. DEFINITIONS

In this Agreement, the following terms shall have the following defined meanings:

"Affiliate" has the meaning contemplated for that term in the Securities Act, RSA 2000 c. S-4 as amended to the date hereof;

“Affected Companies” means Capital Power Corporation and ATCO Ltd.;

“Coal-Fired Emissions” means emissions into the atmosphere from the combustion of coal including air contaminants such as sulphur dioxide, nitrogen oxides, mercury, primary particulate matter, and carbon dioxide and other specified gases as defined in the Climate Change and Emissions Management Act and regulations thereunder;

"Parties" means, collectively, the Company, TGP, TCLP and the Province, and “Party” means any one of them;

“Plant Owners” means K3LP, TGP and TCLP, and “Plant Owner” means any one of them;

"Plants" means the coal powered electricity generation plants known as Keephills Generating Station Unit 3, Genessee Generating Station Unit 3, Sheerness Generating Station Unit 1 and Sheerness Generating Station Unit 2; and

"Transition Payment" has the meaning set forth in Section 3(a) of this Agreement.

2. CESSATION OF COAL-FIRED EMISSIONS

The Company shall cause the Plant Owners to ensure and each of the Plant Owners shall ensure that the Plants will cease Coal-Fired Emissions from the Plants on or before December 31, 2030. It is understood and agreed that in respect of any Plant where the Company or a Plant Owner holds less than a 100% interest in the applicable Plant, this covenant applies only to the extent of the electricity production owned, controlled and dispatched by the applicable Plant Owner from that Plant. For greater certainty, nothing in this Agreement shall prevent or restrict any Plant from generating electricity at any time by any method other than by the combustion of coal.

3. payments

(a) Subject to the Company meeting the eligibility conditions in Section 5 and the obligations in Sections 6 and 7, the Province covenants and agrees to pay to, or as directed by, the Company fourteen (14) annual payments each of $39,851,704.60 (in aggregate, the “Transition Payment”).

(b) The Transition Payment shall be paid in annual payments of $39,851,704.60 on or before July 31 in each year commencing in 2017, with the first payment being payable on or before July 31, 2017, and the last payment being payable on or before July 31, 2030. The Company shall provide bank account payment instructions for payment to the Province concurrently with the execution of this Agreement, and thereafter in accordance with a notice under Section 11(k) of this Agreement.

(c) If the Company fails to meet the eligibility conditions in Section 5 and meet the obligations in Sections 6 and 7 and fails to cure such failure within 90 days of notice from the Province (without regard for the original time by which an eligibility condition was to be satisfied or performance was to occur, if any), then the Province shall not be required to make any further unpaid payments under this Agreement. The Province’s sole rights and remedies in the case of the Company’s failure to meet any of the eligibility conditions in Section 5 or to perform any of the obligations in Sections 6 and 7 or to cure any of such foregoing failures are provided in this Section 3(c) provided that, in the event the Company brings an action contrary to Section 7, then the Province shall be entitled to raise Section 7 as a defence to such an action.

(d) If the Company or any of the Plant Owners fail to fulfill the covenant in Section 2, then, in addition to any other remedies the Province may have at law (including injunctive relief), the Company shall repay the full amount of the Transition Payment actually received by the Company under this Agreement.

-3-

4. EQUIVALENT RIGHTS

(a) The Parties acknowledge that the Province is under no legal obligation to compensate or otherwise pay any amount to the Company as result of the phase out of Coal Fired Emissions (other than under the terms of this Agreement); nevertheless, the Province determined the amount of the Transition Payment in accordance with the formula attached in Schedule A hereto. If the Province enters into a similar off-coal agreement with any of the Affected Companies or their Affiliates and uses a different formula that, if applied to the Company, would result in a materially higher Transition Payment, then the Province will pay the difference to the Company in equal increments over the remaining annual payment dates. In this section, "materially higher" means a difference of at least $5 million over 14 years.

(b) The parties further acknowledge that the Province relied on information from the Company in relation to some of the inputs into the formula, specifically, the net book value of the Plants. If, as a result of a review or examination under Section 6, the Province determines, acting reasonably, that the net book value is lower than the value provided by the Company, then the Province may recalculate the Transition Payment and reduce the Transition Payment on the basis of the formula attached in Schedule A hereto.

5. ELIGIBILITY FOR PAYMENT

During the period commencing on the date of this Agreement and ending on December 31, 2030, the Company will comply with the following eligibility conditions:

(a) The Company, on a consolidated basis, shall spend a minimum of XXXXXXXXXXXX each calendar year on investment and investment related activities in Alberta with respect to its electricity business. For purposes of this Section 5(a), “investment and investment related activities” includes:

(i) any and all capital expenses of any nature or kind, including new capital investments, sustaining capital expenditure or major maintenance capital expenditure; and

(ii) any and all development costs or expenses of any nature or kind, including those incurred in relation to the preparation or submission of bids, production or procurement of studies, including technical feasibility studies and environmental impact assessments, obtaining, maintaining or appealing regulatory approvals, stakeholder engagement, and planning; and

(iii) any and all costs of infrastructure development, construction, maintenance, or decommissioning;

(b) The Company shall continually maintain a significant business presence in the Province of Alberta by:

(i) maintaining its registered and head office in Alberta;

(ii) maintaining employment of at least XXXXXX employees in Alberta; and

(iii) continuing to generate electricity or otherwise participating in the electricity market in Alberta;

provided, that, in the event that a majority of the shares of the Company are acquired by an arm’s length third party or substantially all of the assets of the Company are transferred to an arm’s length third party, the condition related to the head office shall no longer apply. In the event the Province provides a notice to the Company under Section 3(c) of a failure to meet an eligibility condition in this Section 5(b) which was to be continuously met and the Company cures such failure within the cure period, such failure will be deemed never to have occurred for the purposes of this Section 5(b).

(c) The Company, on a consolidated basis, shall each calendar year provide XXXXXXXXX towards programs and initiatives to support the communities surrounding the Plants and the employees of the Company and employees of the Plant Owners negatively affected by the phase out of coal-fired generation at the Plants which may include programs and initiatives recommended by the Advisory Panel on Coal Communities.

(d) The Company shall fulfill its existing and future legal obligations to affected employees, including severance and pension obligations.

6. REPORTING

(a) The Company will deliver a report, certified by a senior officer (without personal liability), to the Minister of Energy and the Minister of Economic Development and Trade (or their respective successors) each year by May 31 confirming that, as of the prior December 31, the eligibility conditions in Section 5 were satisfied and providing reasonable detail in respect of such confirmation and such further information as the Province may reasonably request in relation to the Company’s performance of its obligations and fulfilling the eligibility conditions under this Agreement.

(b) The Company will permit the Province or the Province’s representative, on reasonable notice, during normal business hours, to examine and take copies of the records of the Company in relation to the performance of its obligations and meeting the eligibility conditions under this Agreement and in relation to any information provided by the Company or the Plant Owners in the course of negotiating this Agreement related to the net book value of the Plants. The Province shall treat the information made available to the Province under this Section 6(b) in substantially the same manner as if it was “Confidential Information” under the Confidentiality Agreement between the Province, the Company and other parties dated April 1, 2016.
