(i) the AY Articles are amended in a manner that adversely affects the rights of such Investor (or any Affiliate thereof) to appoint Directors, as such rights exist under the AY Articles as of the Effective Date, unless such Investor or any Affiliate thereof voted in favor of such amendment; or

(ii) except to the extent necessary to comply with applicable law or any order, decree, decision or judgment of any court, tribunal, arbitrator, governmental agency or regulatory body, or where the AY Articles are amended upon a valid proposal made by a shareholder of the Company, the Company or the AY Board takes any action in violation or contravention of the rights of such Investor (or any Affiliate thereof) specified in Clause 2.1(c), provided that such Investor gives notice to the Company reasonably requiring it to remedy such violation or contravention and the Company or AY Board fails to remedy such violation or contravention within twenty (20) Business Days of the Company receiving such notice.

(e) Termination of the obligations and restrictions applicable to an Investor and its Affiliates in accordance with Clause 2.1(d) shall not release such Investor and its Affiliates from any liability which at the time of termination has already accrued to another Party or which thereafter may accrue in respect of any act or omission prior to such termination.

(iii) the Company or the AY Board, other than reasonably in accordance with its ordinary course practices with respect to stated dividends or reasonably in accordance with principles of prudent management with respect to the Company’s existing business, takes or omits to take any action that is reasonably within its control, and such action or omission prevents the Company from lawfully declaring dividends substantially in accordance with the 80% Pay-Out Ratio, and the Company or the AY Board, as applicable, fails to remedy such occurrence within sixty (60) days following receipt by the Company of written notice thereof from an Investor.

(c) Termination of the obligations and restrictions applicable to an Investor and its Affiliates in accordance with Clause 2.2(b) shall not release such Investor Parties from any liability which at the time of termination has already accrued to another Party or which thereafter may accrue in respect of any act or omission prior to such termination.

ARTICLE 4

STANDSTILL

4.1 Standstill.

(a) During the Standstill Period, except as provided in Clause 4.2, no Investor shall, and each Investor shall procure that no Affiliate of such Investor shall, directly or indirectly and either alone or together, by any manner acquire or seek to acquire (or agree to, offer to, accept an option or offer to, or enter into any discussions or agreements to, acquire), whether by purchase, contract or otherwise, any ownership interests or voting rights (or rights or options to acquire such interests or rights) in any AY Voting Securities if the acquisition of the number of the voting rights attached to such AY Voting Securities by such Investor and/or any of its Affiliates, directly or indirectly, when added to the number of the voting rights attached to all AY Voting Securities then held by such Investor and/or its Affiliates, in the aggregate, would result in such Investor and/or its Affiliates holding, directly or indirectly, in the aggregate more than the Standstill Percentage of the total voting rights attached to all then outstanding AY Voting Securities.

(b) Notwithstanding the foregoing, any Investor Party may at any time acquire (and agree to, offer to, accept an option or offer to, or enter into any discussions or agreements to, acquire), whether by purchase, contract or otherwise, from any other Investor Party any ownership interests or voting rights (or rights or options to acquire such interests or rights) in any AY Voting Securities, so long as (i) the aggregate Percentage Interest of all Investor Parties, collectively, does not exceed forty-one and a half per cent (41.5%), except as provided in Clause 4.2, and (ii) promptly following such acquisition, the Investors deliver to the Company written notice of any reallocation between them of the aggregate Standstill Percentage of forty-one and a half per cent (41.5%) as may be required such that no Investor Party is in violation of Clause 4.1(a) as a result of such acquisition.

(c) In no case shall the existence of any option or agreement to acquire all or any portion of the Option Shares, or any discussion of any of the foregoing, constitute a violation of this Agreement.

4.2 Temporary Limited Exceptions.

(a) Subject to Clause 4.2(b), in the event that as a result:

(i) the acquisition of all or any portion of the Option Shares or of any voting rights attached to any Option Shares; and

(ii) the exercise of subscription rights as part of the Initial Funding Commitment,

an Investor and/or its Affiliates hold in the aggregate more than the Standstill Percentage of the total voting rights attached to all then outstanding AY Voting Securities, such Investor will not be in breach of Clause 4.1(a), but until the aggregate Percentage Interest of such Investor and its Affiliates of the total voting rights attached to all then outstanding AY Voting Securities is again equal to or below the Standstill Percentage, such Investor shall not, and such Investor shall procure that its Affiliates shall not, directly or indirectly, acquire any additional AY Voting Securities, whether through subscription from the Company, open market purchases, or any other transaction, other than as described in subclauses (i) and (ii) of this Clause 4.2(a).

(b) If the exercise of the rights of an Investor and its Affiliates to subscribe for AY Voting Securities as part of the Initial Funding Commitment may result in such Investor and/or its Affiliates holding in the aggregate more than the Standstill Percentage of the total voting rights attached to all AY Voting Securities outstanding immediately following the allotment or issue, the Company may give notice to such Investor that such Investors and their Affiliates may subscribe for up to such portion of AY Voting Securities (the “Relevant Portion”) that would be necessary to procure that the number of the voting rights attached to AY Voting Securities that would be held by the Investors and their Affiliates, in the aggregate, immediately following such allotment or issue would not exceed forty six per cent (46%) of the total voting rights attached to all AY Voting Securities that would be outstanding immediately following such allotment or issue. Upon receipt of such notice such Investor shall not, and shall procure that its Affiliates shall not, subscribe for more than the Relevant Portion.

(c) If AAGES is not an Affiliate of AQN, the exception set forth in Clause 4.2(a) and the further limitation set forth in Clause 4.2(b) applies:

(i) if the acquisition of all or any portion of the Option Shares occurred prior to AAGES ceasing to be an Affiliate of AQN, to all Investors; or

(ii) if the acquisition of all or any portion of the Option Shares occurred after, but not prior to, AAGES ceasing to be an Affiliate of AQN, to AAGES or AQN which, or the Affiliate of which, holds the Option Shares (as applicable).

(d) Notwithstanding Clause 4.1(a), in the event that the Company takes any action that reduces the number of the then outstanding AY Voting Securities and, as a result of such action, an Investor and/or its Affiliates then hold in the aggregate more than the Standstill Percentage of the total voting rights attached to all then outstanding AY Voting Securities, such Investor will not be in breach of Clause 4.1(a); provided, however, that until the aggregate Percentage Interest of such Investor and its Affiliates of the total voting rights attached to all then outstanding AY Voting Securities is again equal to or below the Standstill Percentage, such Investor shall not, and such Investor shall procure that its Affiliates shall not, directly or indirectly, acquire any additional AY Voting Securities, whether through subscription from the Company, open market purchases, or any other transaction, other than as described in subclauses (i) and (ii) of Clause 4.2(a).

4.3 Additional Terms.

(a) This Agreement does not restrict the ability of any Investor Party to acquire additional Equity Securities of the Company from any third party, through the public markets or otherwise, so long as such acquisition is not in breach of Clauses 4.1 and 4.2.

(b) Other than limitations set forth in Clause 2.1(b) on the rights of the Investor Parties to appoint Directors to the AY Board pursuant to the AY Articles and subject to Clause 4.3(c), nothing in this Agreement shall be deemed to prohibit or restrict in any way the rights of any Investor or any Affiliate thereof to exercise any and all rights and privileges as a holder of any Equity Securities of the Company (and of voting rights attached to AY Voting Securities) that such Investor and its Affiliates are permitted to hold pursuant to Clauses 4.1 and 4.2, and the existence or exercise of such rights shall not be deemed to constitute Control, including the right to: (i) vote such AY Voting Securities in any manner in the sole and absolute discretion of such Investor or Affiliate thereof, on any and all matters; (ii) make any director nomination or shareholder proposal or support in any manner any director nomination or shareholder proposal made by any other Person; (iii) seek to have called any meeting of the shareholders of the Company; (iv) sell, transfer or exchange, or elect not to sell, transfer or exchange, any Equity Securities of the Company to any Person in any transaction whatsoever, including any merger with or tender, exchange or other offer or proposal by any Person, and encourage or discourage, or support or oppose, any such transaction or offer (other than any transaction with or offer by any Investor Party that would result in a violation of Clause 4.1 by any Investor Party); and (v) communicate in any manner with other holders of any Equity Securities of the Company.

(c) If any Investor or its Affiliates acquire (whether through subscription, open market purchase or any other transaction) any AY Voting Securities or voting rights in breach of Clause 4.1 (subject to Clause 4.2), neither such Investor nor its Affiliates shall be able to exercise that portion of voting rights attached to AY Voting Securities (whether or not such AY Securities themselves are held by such Investor or its Affiliates) that exceeds the voting rights that such Investor and its Affiliates are permitted to hold pursuant to Clauses 4.1 and 4.2. This Clause 4.3(c) and the rights of the Company to terminate this Agreement under Clause 8.2 shall be the sole and exclusive remedies for any breach by any Investor or its Affiliates of Clause 4.1.

(d) For the avoidance of doubt, the obligations and limitations set forth in this Article 4 apply to an Investor and each of its Affiliates both individually and collectively, and to their aggregate holdings of the voting rights attached to AY Voting Securities, such that all voting rights attached to AY Voting Securities acquired or held by an Investor or Affiliate thereof are deemed for purposes of the limitations specified in this Article 4 to be acquired or held by such Investor and each and every Affiliate of such Investor.

(e) This Agreement supersedes any “standstill” or similar provisions between the Company and AQN or any Affiliates thereof under any prior agreement, including those set forth in that certain Non‑Disclosure Agreement between the Company and Algonquin Power Co. dated 15 June 2017, as amended on 3 July 2017 and as further amended effective on 15 December 2017, which the Parties agree shall be terminated in its entirety promptly following execution and delivery of this Agreement.

To the extent that the disclosure of such information is not prohibited by applicable law or the AY Articles, upon a reasonable written request of any Investor the Company shall provide such Investor with such financial statements, reports and other information that are customarily disclosed by the Company to its other shareholders, except where such information may, in the reasonable opinion of the AY Board, reasonably give rise to an actual or potential, direct or indirect, conflict of interest between the Company, on the one hand, and such Investor or its Affiliates (or any investor therein), on the other hand or the AY Board designates any such information as “commercially sensitive” or, in the reasonable opinion of the AY Board, the information is likely to cause damage to the Company or any of its Subsidiaries. In the event of a conflict of interest, the Company will be entitled to undertake any procedure for managing such conflicts of interest or in connection with the situation or matter in question in accordance with the AY Articles and applicable law.

7.2 Reliance. The Company shall be entitled to rely, without inquiry whatsoever, on any action taken, or the failure to take any action, by the Investor Party Representative hereunder, on behalf of an Investor Party for which such Investor Party Representative has been appointed.
