Board do not intend to stand for re-election at the next following ASM. Within 60 days following any such initial meeting, the Investor and the GSSC shall separately consider the applicable skills, competencies and requirements recommended for any replacement Investor Nominees having regard to the requirements in Section 5.1(a) and shall meet to discuss the Investor’s proposed replacement Investor Nominee(s) to be considered for nomination at the next ASM. As soon as practicable following any of these discussions, the Investor shall provide one or more notices setting out its proposed replacement Investor Nominee(s) along with (i) sufficient background information about any nominee who is not an incumbent director on the Board or (ii) in the case of an incumbent director on the Board whose circumstances have materially changed, sufficient information about the material change, so as in either case to allow the GSSC to assess whether the Investor Nominee(s) satisfy the qualifications and requirements set out in Section 5.1(a). Within 30 days of receipt of such notice, the GSSC shall have 30 days to confirm or reject the proposed Investor Nominee(s), but may reject that nominee only on the grounds that such nominee does not satisfy the qualifications for directors set out in Section 5.1(a). Any Investor Nominee who is not rejected by the GSSC within such 30-day period shall be proposed by the GSSC for election as a director in accordance with Section 5.1(a). If any Investor Nominee(s) is rejected pursuant to this Section 5.1(b), the Investor shall be entitled to deliver one or more nomination notices nominating a replacement Investor Nominee until a nominee is confirmed by the GSSC. Each of the Investor and the GSSC shall, in any event, work cooperatively and in good faith with each other to identify and confirm two (2) Investor Nominees to be recommended for election to the Board at each ASM at least 60 days prior to the date by which proxy solicitation materials must be mailed for purposes of the next following ASM, repeating the foregoing process as often as is required in order to identify and confirm two (2) Investor Nominees by such deadline,

(c) The Issuer shall use commercially reasonable efforts to ensure that the Investor Nominees are elected to the Board at the 2019 ASM and at each subsequent ASM, for so long as the Investor holds Exchangeable Securities, including soliciting proxies in support of their election and taking the same actions taken by the Issuer to ensure the election of the other nominees selected by the Board for election to the Board.

(d) Each Investor Nominee must be an individual of high quality and integrity who has significant experience and expertise in business or that is applicable to business, served in a senior executive, leadership or entrepreneurial position, broad exposure to and understanding of the Canadian business community, skills for directing the management of a company, and motivation and availability, in each case, to the extent requisite for a business of the complexity, size and scale of the business of the Issuer and on a basis consistent with the highest standards for directors of similarly situated Canadian publicly listed companies. The Investor shall advise the Issuer of the identity of an Investor Nominee at least 60 days prior to any meeting of shareholders at which directors of the Issuer are to be elected or within 20 days of being notified of the record date for such a meeting. If the Investor does not advise the Issuer of the identity of an Investor Nominee prior to such deadline, then the Investor will be deemed to have nominated their incumbent nominee.

(e) The initial Investor Nominees will be: (i) Xxxxxxx Xxxxxxx and (ii) Xxxxx Xxxxxxx, which nominees the GSSC and the Board have determined satisfy the requirements of Section 5.1(a) and, accordingly, the Board shall nominate such Investor Nominees for election to the Board by the shareholders at the 2019 ASM.

(f) In the event that an Investor Nominee shall unexpectedly cease to serve as a director of the Issuer, whether due to such Investor Nominee's death, disability, resignation or

- 36 -

removal, the Issuer shall cause the Board to promptly appoint a replacement Investor Nominee (who shall be a different person) designated by the Investor to fill the vacancy created by such death, disability, resignation or removal, provided that the Investor remains eligible to designate an Investor Nominee and that the replacement Investor Nominee satisfies the requirements of Section 5.1(a). If, notwithstanding the expectations of the Investor and the Issuer regarding any Investor Nominees being nominated for or agreeing to stand for re-election at the next following ASM, there is any unexpected death, disability, resignation or removal less than 60 days prior to or at the ASM, if and to the extent a replacement Investor Nominee for such departing Investor Nominee cannot be identified and confirmed in sufficient time for election at the next ASM, the Investor’s obligations under Sections 4.3, 4.5, 4.6 and 4.9 shall continue to apply until the date that is 45 days following the date on which the Investor has provided notice of a replacement Investor Nominee to the GSSC.

(g) Each Investor Nominee shall be compensated for his or her service and reimbursed for expenses related to such service consistent with the Issuer’s policies for director compensation and reimbursement.

(h) The Issuer shall indemnify an Investor Nominee and provide the Investor Nominee with director and officer insurance to the same extent it indemnifies and provides insurance for the members of the Board pursuant to its organizational documents, applicable Law or otherwise.

5.2	Hydro Assets Operating Committee

(a) The Board shall establish a committee by the commencement of the Operating Committee Period that is to be named the “Hydro Assets Operating Committee” (the “Operating Committee”).

(b) The Operating Committee shall provide advice to management of the Issuer in connection with the operation, and maximizing of value, of the Hydro Assets. The Operating Committee shall consist of two (2) persons employed by the Investor and having expertise in management of hydro facilities and two (2) representatives of the Issuer.

(c) During the Operating Committee Period, the Investor shall be paid a management fee of $1,500,000 per year (the “Management Fee”) commencing on the First Funding Date and annually thereafter for a total of six payments of $1,500,000.

(d) The Operating Committee Period may be extended by the Issuer for up to two additional one year periods and an annual Management Fee shall be payable for each such year extended term.

(b)

any breach or non-performance by any Investor of any covenant to be performed by it contained in this Agreement, or in any agreement, certificate or other document delivered to the Issuer by the Investor pursuant hereto.

6.3	Notice of Claim

In the event that a party (the “Indemnified Party”) shall become aware of any claim, proceeding or other matter (a “Claim”) in respect of which another party (the “Indemnifying Party”) agreed to indemnify the Indemnified Party pursuant to this Agreement, the Indemnified Party shall promptly give written notice thereof to the Indemnifying Party. Such notice shall specify with reasonable particularity (to the extent that the information is available) the factual basis for the Claim and the amount of the Claim, if known.

If, through the fault of the Indemnified Party, the Indemnifying Party does not receive notice of any Claim in time to contest effectively the determination of any liability susceptible of being contested, the Indemnifying Party shall be entitled to set off against the amount claimed by the Indemnified Party the amount of any Losses incurred by the Indemnifying Party resulting from the Indemnified Party’s failure to give such notice on a timely basis; provided, however, that an Indemnifying Party shall not be entitled to any set off if the

- 38 -

failure by the Indemnified Party to timely give notice of a Claim does not prejudice such Indemnifying Party.

6.4

Claims

Following receipt of notice from the Indemnified Party of the Claim, the Indemnifying Party shall have 30 days to make such investigation of the Claim as is considered necessary or desirable. For the purpose of such investigation, the Indemnified Party shall make available to the Indemnifying Party the information relied upon by the Indemnified Party to substantiate the Claim, together with all such other information as the Indemnifying Party may reasonably request. If both parties agree at or prior to the expiration of such 30-day period (or any mutually agreed upon extension thereof) to the validity and amount of such Claim, the Indemnifying Party shall immediately pay to the Indemnified Party the full agreed upon amount of the Claim.

6.5	Computation of Indemnifiable Losses

In calculating any Losses, the amount payable in respect of any Claim shall be reduced to reflect any compensation actually received by the Indemnified Party from any insurance claim (an “Insurance Benefit”), provided that the amount of such Insurance Benefit is not subject to reimbursement as a result of the amount payable in respect of such Claim; provided, however, that such reduction shall not apply to the extent of any retroactive adjustments or increase in insurance premium of such Indemnified Party.

6.6	Monetary Limits on Indemnification

(a) No Claim shall be made pursuant to Sections 6.1 or 6.2 until the aggregate Losses suffered or incurred by the Indemnified Party in respect of all matters which could be the subject of such a Claim exceed $1,500,000, at which time the Indemnified Party may make Claims in respect of all Losses, including, for greater certainty, the Losses included in such $1,500,000 amount. Subject to 6.6(b) below, an Indemnifying Party shall have no liability to indemnify an Indemnified Party for any Losses after the aggregate of all successful Claims for Losses made by the Investor under Section 6.1 or by the Issuer under Section 6.2, as the case may be, exceeds the aggregate Investment Amount that has been paid at the time of any notice of the Claim. In view of the limitations on indemnification set forth in this Section 6.6, for the purposes of determining whether the $1,500,000 deductible amount referenced above has been exceeded with respect to a Claim for breach of a representation and warranty, the concepts of materiality, Material Adverse Effect, Hydro Material Adverse Effect, “in all material respects” and other similar qualifying language contained in such representation and warranty and any certification relating thereto of or on behalf of the Issuer shall be disregarded, provided for certainty that such qualifying language as to materiality shall not be disregarded for the purposes of establishing whether or not there has been a breach of representation and warranty so as to give rise to a Claim.

(b) The limitation on liability herein in respect of any breach of a covenant in (x) Sections 4.2(a)(ii), 4.2(a)(iii), 4.2(a)(iv), 4.2(a)(v), 4.2(b)(ii), 4.2(b)(iv), 4.2(b)(ix) or 4.2(b)(xi); and (y) Sections 4.2(b)(vi) and 4.2(b)(viii) where such breach impairs the Exchange Right, in each case, is the Investment Amount that has been paid at the time of any notice of the Claims plus 10% of that Investment Amount.

- 39 -

6.7	Exclusivity

The provisions of this Article 6 shall apply to any claim for breach of any representation and warranty of this Agreement (other than a claim for specific performance or injunctive relief) with the intent that all such claims shall be subject to the limitations and other provisions contained in this Article 6. Notwithstanding anything to the contrary contained herein, no limitation or condition of liability or indemnity shall apply to any rights or claims based upon fraud or intentional misrepresentation and nothing contained herein shall prevent an indemnified party from pursuing remedies as may be available to such party under applicable Law in the event of an indemnifying party’s fraud, intentional misrepresentation or other intentional misconduct.

SCHEDULE A

EXCHANGEABLE SECURITIES TERMS

Term:		Redeemable Shares: Perpetual. Exchangeable Debentures: 20 years from Initial Funding Date.

Ranking:		Redeemable Shares: There will be a fixed number of 400,000 Redeemable Shares authorized for issuance. The Redeemable Shares will rank pari passu to all existing series of First Preferred Shares of the Issuer with respect to dividends and liquidation preference. Exchangeable Debentures: There will be a fixed number of 350,000 Exchangeable Debentures authorized for issuance. The Exchangeable Debentures will rank subordinate to all existing and future secured and senior unsecured indebtedness of the Issuer, including the Issuer’s existing credit facility. The Issuer’s obligations under the Exchangeable Securities will not be guaranteed by any of its subsidiaries.

Dividend/Interest:		Redeemable Shares: 7% per annum cumulative dividend payable quarterly in cash. The Issuer must pay unpaid dividends on the Redeemable Shares prior to making any other payment (distribution, repurchase or otherwise) on any other classes of equity of the Issuer, other than in connection with the SIB or a normal course issuer bid. Exchangeable Debentures: Interest will accrue at 7% per annum from the First Funding Date payable quarterly in cash in arrears.
Exchange Right:		At any time after December 31, 2024, Investor shall be entitled to require the Issuer to redeem or exchange, as applicable, all but not less than all of the Exchangeable Securities then held by the Investor and its Affiliates minus that number of Exchangeable Securities that are specified in a notice of Optional Redemption (if any) issued by the Issuer where such Optional Redemption has not been completed, for the Redemption Price (the “Exchange Right”).
Optional Redemption:		At any time after December 31, 2028, the Issuer shall have the option to redeem the Exchangeable Securities, in whole or in part (“Optional Redemption”), at the Redemption Price provided that the minimum proceeds to Investor for each such redemption (other than the final redemption) must be not less than $100,000,000 and further provided all Exchangeable Securities must be redeemed within 36 months of the date on which the first Optional Redemption occurs. “Redemption Price” means (1) for each Redeemable Share being redeemed, the subscription price paid by the Investor for such Redeemable Share, together with all accrued but unpaid dividends thereon, and (2) in respect of each Exchangeable Debenture being redeemed, a redemption price equal to 100% of the principal amount of such Exchangeable

- 1 -

		Debenture plus accrued and unpaid interest thereon. The Redemption Price shall be satisfied in the manner set forth below under “Satisfaction of Redemption Price”.
Satisfaction of Redemption Price:		Upon the Redemption Price becoming payable pursuant to (i) the Investor’s exercise of the Exchange Right or the occurrence of an Equity Acceleration Event, Investor shall receive the Equity Redemption Amount; or (ii) an Optional Redemption or the occurrence of a Cash Acceleration Event, the Investor shall receive the Cash Redemption Amount. “Equity Redemption Amount” shall mean an equity interest in Hydro Assets Owner (as defined below) equal to (i) the aggregate Redemption Price for all Exchangeable Securities issued to Investor divided by (ii) the Tax Affected Hydro SPV Equity Value, provided that such Hydro Equity Interest in the Hydro Assets Owner shall not exceed 49% of all issued and outstanding equity interests of Hydro Assets Owner (the “Hydro SPV Equity”). To the extent that the Hydro Equity Interest would exceed 49% of the Hydro SPV Equity, the balance of the aggregate Redemption Price for all Exchangeable Securities shall be paid by the Issuer by the delivery of cash. If the Optional Redemption is exercised in part, but not whole, the Equity Redemption Amount will be adjusted accordingly. In the event of any material damage or destruction to the Hydro Assets, the Issuer and the Investor shall equitably adjust the Tax Affected Hydro SPV Equity Value to reflect such damage or destruction and the anticipated impact on EBITDA. “Cash Redemption Amount” means the Redemption Price of the Exchangeable Securities being redeemed to be paid in immediately available funds paid by wire transfer to Investor. “Hydro Assets” means the hydro generation facilities described in Schedule C, together with such other assets used to operate such facilities. “Hydro Assets Owner” means a limited partnership or other entity to be agreed between Investor and the Issuer that shall hold directly or indirectly the interests in the Hydro Assets. “Hydro Covenant Breach” means a breach of the covenant to complete the Hydro Asset Reorganization in the manner described in the Investment Agreement. “Hydro SPV Equity Value” means thirteen (13) x EBITDA of the Hydro Assets for the three fiscal years ending immediately prior to the exercise of each Top-Up Option other than a Top-Up Option upon a Hydro Covenant Breach. “EBITDA”, for purposes of the Investor’s exercise of the Exchange Right or the occurrence of an Equity Acceleration Event at any time on or after January 1, 2024, shall be calculated as set out in Appendix 1 hereto.

- 2 -

		“Tax Deficiency Value” for the purposes of the calculation of the Tax Affected Hydro SPV Equity Value shall be calculated as set out in Appendix 2 hereto. “Tax Affected Hydro SPV Equity Value” means thirteen (13) x EBITDA of the Hydro Assets for the three fiscal years ending immediately prior to the date of exercise of the Exchange Right, less the Tax Deficiency Value; provided, however, that, in the case of an Equity Acceleration Event, Permitted Hydro Asset Sale or exercise of the Top-Up Option upon a Hydro Covenant Breach on or prior to December 31, 2024, the Tax Affected Hydro SPV Equity Value shall be deemed to be $1.95 billion at the time of such event and subject to future adjustment (if applicable) in accordance with the “Acceleration True-Up” below or at time of exercise of the Put Right (as defined in the SPV Governance Terms).
Top-Up Option:		If at the time the Exchange Right is exercised (including, for clarity, in connection with a Permitted Hydro Asset Sale, or an Equity Acceleration Event resulting from a Hydro Covenant Breach), the Equity Redemption Amount is not sufficient to permit Investor to acquire a 49% Hydro Equity Interest, the Investor shall have a one-time option (“Top-Up Option”), exercisable until December 31, 2028, to acquire the following additional Hydro SPV Equity provided that the Investor holds at the time of exercise of such option at least 8.5% of the issued and outstanding Common Shares:

	●	if the 20 day VWAP of the Common Shares (at the time the Exchange Right is exercised) is not less than $14, up to an additional 10% of such Hydro SPV Equity (to a maximum equity interest of 49%), or

	●	if the 20 day VWAP of the Common Shares (at the time the Exchange Right is exercised) is not less than $17, that percentage of additional Hydro SPV Equity that would allow the Investor to hold 49% of the Hydro SPV Equity,

in each case by paying to the Issuer, in cash, for such additional Hydro SPV Equity the Hydro SPV Equity Value (other than in respect of a Hydro Covenant Breach, where Investor will pay the Tax Affected Hydro SPV Equity Value) multiplied by the additional percentage of Hydro SPV Equity so acquired.

Notwithstanding the foregoing and regardless of the number of issued and outstanding Common Shares then owned by the Investor, if at the time the Exchange Right is exercised or an Equity Acceleration Event or Permitted Hydro Asset Sale occurs, the Equity Redemption Amount is not sufficient to permit Investor to acquire a 25% interest in the Hydro SPV Equity, the Investor shall have the option to acquire that percentage of additional Hydro SPV Equity that would allow the Investor to hold 25% of the Hydro SPV Equity for a price calculated on the same basis as above, paid by the Investor to the Issuer in cash. If the Investor exercises this top-up option, the Investor will become subject to the Additional Lock-Up Period on the

- 3 -

		terms described in the Investment Agreement.

Acceleration Events:		Upon the occurrence of an Acceleration Event, upon written notice by the Investor to the Issuer, the Issuer shall be required to redeem all of the outstanding Exchangeable Securities at the Redemption Price (and satisfied in the manner set forth in “Satisfaction of Redemption Price”). The occurrence of any of the following will constitute an “Acceleration Event”:

	1.	Bankruptcy / Insolvency: the Issuer (i) files any petition or action for relief under any bankruptcy, reorganization, insolvency or moratorium law or any other law for the relief of, or relating to, debtors, or makes any assignment for the benefit of creditors or takes any corporate action in furtherance of any of the foregoing, or an involuntary petition is filed against the Issuer (unless such petition is dismissed or discharged within thirty (30) days), or a custodian, receiver, trustee, assignee for the benefit of creditors (or other similar official) is appointed to take possession, custody or control of any property of the Issuer or (ii) takes any steps to, or undertake any proposal for, the winding-up or liquidation of the Issuer, obtain an administration order, or appoint a receiver in respect of the whole or any part of the Issuer;
	2.	Regulatory Approvals: provided that the Hydro Asset Reorganization is completed in the manner described in the Investment Agreement, any regulatory approvals that would prevent the Issuer from satisfying the Redemption Price for the Equity Redemption Amount are not obtained on terms acceptable to Investor and the Issuer, acting reasonably;
	3.	Litigation Proceedings: a final order is issued that enjoins either the Second Funding or the completion of the Exchange Right;
	4.	Breach of Covenants: subject to customary cure periods in respect of Sections 4.2(a)(iv) and 4.2(a)(v), a breach by the Issuer of any of the negative covenants or the covenants in Section 4.2(b)(i), (ii) and (iv) described under “Covenants” in this Investment Agreement;
	5.	MAE: the occurrence of a Material Adverse Effect or Hydro Material Adverse Effect after the Initial Funding Date and prior to the Second Funding Date.

An Acceleration Event of the type specified immediately above in #2 or #3, above is referred to in this term sheet as a “Cash Acceleration Event”. An Acceleration Event of the type specified immediately above in #1, #4 or #5 is referred to in this term sheet as an “Equity Acceleration Event”; provided however, that with respect to #4, if the relevant breach of covenant is Section 4.2(b)(iv) of the Investment Agreement and the reason for such breach is the failure to obtain required regulatory approvals and the Issuer is otherwise in compliance with its covenants under the Investment Agreement in relation to obtaining such regulatory approvals, such Acceleration Event shall then be a Cash Acceleration Event.

- 4 -

Acceleration True-Up:		If an Equity Acceleration Event occurs at any time prior to December 31, 2024, a true-up payment shall be made by the Investor to the Issuer or by the Issuer to the Investor, as the case may be, in an amount equal to the difference between (A) $1.95 billion and (B) the Tax Affected Hydro SPV Equity Value calculated as of a date (to be determined by the Investor) within the period commencing January 1, 2025 and ending December 31, 2028, which true-up payment shall be settled through the transfer of Hydro SPV Equity; provided that in no event shall such true-up payment result in the Investor owning more than a 49% interest in the Hydro Assets Owner and any difference in favour of the Investor between the true-up amount and the value of additional Hydro SPV Equity to be issued to Investor shall be satisfied by the delivery of cash.
Covenants:		Covenants in the Agreement applicable to the Exchangeable Securities or the Hydro Assets will be included in the Exchangeable Securities.
Tax Status:		Unless the Redeemable Shares are “short-term preferred shares” for purposes of the Tax Act, the Issuer will elect to pay tax under Part VI.1 of the Tax Act at such a rate that no tax under Part IV.1 of the Tax Act will be payable by holders of the Redeemable Shares.
