(ii) at all times during which an Investor and/or its Affiliates hold in aggregate twenty-five per cent (25%) or more of the AY Voting Securities and such Investor or its Affiliate has appointed (and continues to have the right to appoint) one or more Directors, at least one Investor Nominee of such Investor shall be given an opportunity to be, and, if he/she accepts such opportunity, shall be, elected to any committee of Directors (except for the audit committee and related party transaction committee); provided that ownership of less than twenty-five per cent (25%) of the AY Voting Securities shall not preclude any Investor Nominee from serving on any committee of Directors, and any such Investor Nominees shall be given the same consideration in relation to serving on any such committee as is given to Directors generally;

(iii) no action of the AY Board shall be taken by Directors’ written resolution unless all of the Investor Nominees who would have been entitled to vote on such resolution if it had been proposed at a meeting of the Directors have: (A) signed one or more copies of it; or (B) otherwise indicated their agreement to it in writing; and

(iv) if, for any reason, and so long as an Investor or its Affiliate has the right to appoint one or more Directors but no such Director is then serving on the AY Board, such Investor shall be entitled to designate one individual to attend all meetings of the AY Board which a Director would have been entitled to vote at if he/she had been appointed by such Investor and of any committee thereof (except for the audit committee and related party transaction committee) as an observer and receive copies of all materials provided to Directors with respect to any such meeting or any written consent or resolution in lieu of such a meeting, further provided that such observer signs customary confidentiality undertakings and complies with the Company’s policies and procedures as and in the manner the Company may request acting reasonably.

(d) Subject to Clause 2.1(e), any Investor shall have the right to terminate the obligations and restrictions applicable to such Investor and its Affiliates under this Agreement, without liability to any Party, immediately upon written notice to other Parties, if at any time:

(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.

2.2 Dividends.

(a) The AY Board by resolution adopted in January 2018 confirmed that it is the objective of the Company to pay dividends on the Shares in an amount equal to eighty per cent (80%) of CAFD (the “80% Pay-Out Ratio”), and prior to the Effective Date has not rescinded, replaced or otherwise modified such resolution.

(b) Subject to Clause 2.2(c), any Investor shall have the right to terminate the obligations and restrictions applicable to such Investor and its Affiliates under this Agreement, without liability to any Party, immediately upon written notice to the Company, if at any time:

(ii) the AY Board does not confirm any pay-out ratio objective, as a percentage of CAFD, by resolution at least once during any period of more than fourteen (14) consecutive months; or

(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.

(d) For the avoidance of doubt, but subject always to the Investor Parties’ rights under Clause 3.2(a), in connection with each proposed allotment or issue of Equity Securities by the Company, the AY Board may decide, in its sole discretion, whether to offer the Investor Parties or any of them the ability to subscribe for and purchase more than (i) their collective Percentage Interest of the proposed allotment, if AAGES is an Affiliate of AQN or (ii) AQN’s or AAGES’s Percentage Interest of the proposed allotment, if AAGES is not an Affiliate of AQN.

3.3 Notice Requirements.

(a) To the extent permitted by applicable law, the Company shall give the applicable Investors specified in Clause 3.2(a) written notice of any proposed offering of Equity Securities by the Company no less than twenty (20) calendar days prior to the earlier of the funding thereof and the execution of any subscription agreement with respect thereto, which notice shall include, to the extent available and applicable:

(i) in the case of a registered public offering, a draft copy of the prospectus included in the registration statement or similar offering documents to be filed in respect of such offering or, in the case of an offering exempt from registration, the draft private placement memorandum or similar offering documents in respect of such offering;

(ii) a description of the anticipated amount of Equity Securities, the price thereof, and all other material terms upon which the Company offers to sell such Equity Securities; and

(iii) the number of Equity Securities that such Investor is entitled to purchase pursuant to Clause 3.2(a).

(b) An Investor (or its Affiliate designee) shall give the Company written notice of its election to subscribe for any such Equity Securities, and the amount thereof, within ten (10) calendar days after the date of the Investor’s receipt of written notice of such proposed offering, including the price thereof, pursuant to Clause 3.3(a).

3.4 Subscription Price.

(a) If any Investor or its Affiliate designee notifies the Company that such Investor and/or any of its Affiliates in the aggregate intend to subscribe pursuant to Clause 3.2(a)(i) or Clause 3.2(a)(ii) (as applicable) for fifty per cent (50%) or more of an offering of Equity Securities that are then listed and traded on a stock exchange, the price per Equity Security for all Persons that participate in such offering (including such Investor and its Affiliates) will be equal to ninety-seven per cent (97%) of the U.S. dollar volume-weighted average Closing Price per Equity Security on the Applicable Exchange over the twenty (20) Applicable Exchange trading days immediately preceding the date of such Investor’s receipt of notice of such proposed offering (the “Trading Period”). If a Closing Price, as derived from the website of the Applicable Exchange or Bloomberg (as applicable) is not in U.S. dollars, the Closing Price shall be converted into U.S. dollars at the exchange rate displayed on the website of the Applicable Exchange (or, if not available on such website, from Bloomberg) as at close of business on the last day of the Trading Period (or if such rate is not displayed on such day, on the immediately preceding day on which such rate is displayed).

(b) Other than as set out at Clause 3.4(a), the price per Equity Security for all Persons that participate in such offering, including such Investor and its Affiliates, will be determined by the Company at its absolute discretion and will be the same for all such Persons.

3.5 Authorizing Action.

(a) The Parties acknowledge that the currently effective disapplication to the Company of pre-emption rights under Section 561(1) of the Companies Act 2006 is limited in amount and time and that, under the AY Articles and applicable law, the rights of the Investors under Clauses 3.2(a)(i) and 3.2(a)(ii) are subject to such limitations. Notwithstanding the foregoing, and subject to Article 4, if at any time the Company allots or issues Equity Securities and, as a result of limitations imposed by applicable law or the AY Articles (including as a result of any failure to have disapplied pre-emption rights during such time period and sufficient in amount), any Investor or Affiliate thereof is unable to fully exercise the rights under Clauses 3.2(a)(i) and 3.2(a)(ii) that such Investor or Affiliate thereof would be entitled to exercise in the absence of such limitations, such Investor shall have the right to terminate the obligations and restrictions applicable to such Investor and its Affiliates under this Agreement, without liability to any Party, immediately upon written notice to the Company.

(b) Termination pursuant to Clause 3.5(a) of the obligations and restrictions applicable to an Investor and its Affiliates 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.

3.6 Initial Funding Commitment.

Subject to Clause 4.2(b), if:

(a) AAGES is an Affiliate of AQN, then, subject to the approval of the board of directors of AQN to provide such funding to AAGES, AAGES hereby undertakes to provide (itself or through a Subsidiary), or

(b) AAGES is not an Affiliate of AQN, then, subject to the approval of the board of directors of AQN to provide such funding to the Company, AQN hereby undertakes to provide (itself or through a Subsidiary),

and the Company undertakes to accept, funding required by the Company for the acquisition of assets and/or interests therein by the Company or its Subsidiaries in one or more transactions during 2018 and 2019 (the “Required Funding Amount”) up to the Initial Funding Commitment Amount (the “Initial Funding Commitment”) by way of subscription for Shares (or other Equity Securities agreed by AAGES or AQN, as applicable) of the Company in accordance with the provisions of Clause 3.2(a), including the obligation to subscribe for any portion of the offered Shares or other agreed Equity Securities that have not been accepted by any other shareholder of the Company and participation in each round of offering of Shares or other agreed Equity Securities until the amount funded by AAGES or AQN, as applicable (or their Subsidiaries) reaches the lesser of (A) the Required Funding Amount and (B) the Initial Funding Commitment Amount.

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.

INFORMATION RIGHTS

6.1 Financial Information. 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.

ARTICLE 2

RIGHT OF FIRST OFFER

2.1 Exclusive Right of First Offer. Pursuant to this Agreement, AAGES grants to AY an exclusive right of first offer for any ROFO Interest in accordance with the terms and conditions set forth in this Agreement, subject only to Existing Rights. Other than Existing Rights, AAGES represents and warrants that it has not and will not grant to any other Person any other right of first offer, right of first refusal or other similar agreements in relation to any ROFO Interests, unless (a) such rights will not be exercisable with respect to any Transfer (or proposed Transfer) of such ROFO Interests to AY pursuant to this Agreement, or (b) AY has consented thereto in writing.

2.2 Consideration. The rights granted to AY in this Agreement are granted in exchange for a Fee paid by any AY Company in exchange for any ROFO Interest, which shall be paid by or on behalf of such AY Company, simultaneously with the closing of the Transfer of such ROFO Interest to an AY Company, to a bank account designated by the AAGES Company that is the seller of such ROFO Interest.

2.3 Restrictions on Negotiations; Status Meetings.

(a) AAGES shall procure that no AAGES Company nor any representative or agent thereof (including any AAGES Owner Company) shall solicit offers from, or negotiate or enter into any agreement with, any Person for the Transfer of a ROFO Asset, ROFO Entity or ROFO Interest (other than a Permitted Transfer or Exempt Transfer) unless AAGES first delivers a Transaction Notice to AY and complies with the terms and provisions of this Article 2 with respect to such ROFO Interest.

(b) At the reasonable request of any Party, representatives of the Parties shall meet, in person or by telephone or video conference (in the discretion of each participant), to discuss material developments related to the construction or operating status of the then-existing ROFO Assets, including completion of construction financing, commencement of construction, then-existing target Commercial Operation Dates, and any Commercial Operation Dates that have been achieved. Meetings pursuant to this Clause 2.3(b) will be held at a time and in such a manner as is mutually convenient for all participants, within a reasonable time following request for such a meeting provided that, absent special circumstances, it is the expectation that such meetings will not be held more frequently than quarterly. Any request for such a meeting may be made informally. All discussions among and information exchanged by the Parties during any such meeting shall be subject to the provisions of Article 6 hereof.

2.4 Transaction Notice.

(a) Prior to any AAGES Company soliciting offers from, or negotiating or entering into any agreement with, any Person for the Transfer of any ROFO Interest or related ROFO Asset or ROFO Entity (other than a Permitted Transfer or Exempt Transfer), AAGES shall deliver to AY written notice of its intent to commence the Negotiation Period with respect to such ROFO Interest, together with copies of (or details for AY to obtain immediate electronic access to) the Transfer Information (as defined herein) related to such ROFO Interest and the related ROFO Asset and ROFO Entities (collectively, a “Transaction Notice”).

(c) For the avoidance of doubt, a Target Interest shall include all direct and indirect Financial Interests of AAGES in the applicable Target Asset, but the Target Entities shall include only those entities related to the Target Asset (including any financing thereof), such that upon a Transfer of such Target Interest to an AY Company, such AY Company shall not thereby directly or indirectly acquire any assets or companies, or directly or indirectly acquire or assume any liabilities, that are unrelated to such Target Asset.

(d) In the event that AAGES has not previously delivered to AY a Transaction Notice with respect to its direct or indirect interest in a particular ROFO Asset, AY may deliver written notice to AAGES (a “Transaction Notice Request”) at any time within twelve (12) months following the date on which such ROFO Asset becomes an Operating Asset, requesting that AAGES commence good faith negotiations with respect to a Transfer of such ROFO Interest to AY. Within sixty (60) days following delivery of a Transaction Notice Request, AAGES shall deliver to AY either:

(i) written notice confirming that AAGES has no present intention to Transfer such ROFO Interest (other than pursuant to a Permitted Transfer or Exempt Transfer), in which case AAGES shall not be obligated to deliver a Transaction Notice to AY except as provided in Clause 2.4(a) and, until such time as such a Transaction Notice is delivered pursuant to in Clause 2.4(a), the provisions of Clauses 2.5, 2.6 and 2.7 shall not apply; or

(ii) a Transaction Notice pursuant to Clause 2.4(a) with respect to such ROFO Interest and, thereupon, the remaining provisions of this Article 2 shall apply thereto; provided, however, that the foregoing shall not obligate AAGES to sell or otherwise dispose of all or any portion of the applicable ROFO Interest to any AY Company or any other Person.

2.5 Transfer Information. As part of any Transaction Notice, AAGES shall make available to AY, electronically or in hard copy, the following information that is then in the possession of or reasonably available to AAGES relating to the applicable Target, all as determined in good faith by AAGES (“Transfer Information”), without limiting AY’s right under Clause 2.6(b) to such additional information as may be reasonably requested by AY during the Negotiation Period:

(a) a reasonably detailed description of the Target Interest, the Target Entities, and the Target Asset;

(g) the most recent version of (and any updates to) the reports and studies, if any, prepared by (i) an independent engineer, including (to the extent then reasonably capable of determination) assessment of the extent to which the Target Asset has been built in accordance with applicable specifications and industry standards, and the extent to which the Target Asset can be expected to deliver the expected performance, and (ii) any geotechnical engineer, environmental consultant, or other consultant with respect to the Target Asset, in the case of each of the foregoing prepared on behalf of or for any AAGES Company or, to the extent available to AAGES, on behalf of or for any Financing Party;

(j) copies of regular, periodic construction and operating reports delivered pursuant to the requirements of any EPC Contract or operating and maintenance agreement;

(k) all notices of any outstanding default, violation or claim (including warranty claims), and any outstanding waivers, from or to counterparties under any Material Contracts;

(l) a list and copies of all material licenses, permits, authorizations and other governmental approvals held by any Target Entity or otherwise related to the Project, and a list of any material licenses, permits, authorizations and other governmental approvals required but not yet obtained;

(p) a draft agreement setting forth proposed terms and conditions for the sale and purchase of the Target Interest (a “Proposed Definitive Agreement”).

2.6 Negotiation Period.

(a) For a period of sixty (60) days following delivery of any Transaction Notice (including the related Transfer Information) (a “Negotiation Period”), the Parties shall discuss and negotiate in good faith, on an exclusive but non-binding basis, to attempt to agree on definitive terms, acceptable to both Parties, upon which the applicable AAGES Companies would transfer the Target Interest to an AY Company.

(b) During the Negotiation Period, AAGES shall, and shall cause any applicable AAGES Company to:

(iii) use commercially reasonable efforts to supplement the financial model provided pursuant to Clause 2.5(f) with such additional data and calculations as may be reasonably requested by AY; and

(iv) otherwise cooperate with AY to facilitate AY’s due diligence assessment of the Target Interest, Target Entities, and Target Asset.

(c) If the Negotiation Period commenced prior to COD but ends after COD (or the parties have entered into a Definitive Agreement with respect to a Transfer but such Transfer has not occurred prior to COD), then with respect to any report delivered pursuant to Clause 2.5(g) that is customarily updated for financing parties at COD (including the independent engineer’s report), AAGES shall cause to be delivered to AY an update to such report reflecting the conditions at COD, once achieved.

(d) At any time during the Negotiation Period, AY shall have the right (but shall not be obligated) to deliver to AAGES on behalf of the applicable AAGES Company a binding written offer for the purchase of the applicable Target Interest by an AY Company in the form of a revised Proposed Definitive Agreement which shall set forth the purchase price and all other material terms and conditions of such proposed Transfer (a “Binding Offer”). Any such Binding Offer shall remain open for acceptance by AAGES on behalf of the applicable AAGES Company for a period of ten (10) Business Days or such longer period as may be stated in such Binding Offer.

2.7 Consummation of Sale to AY

(a) Each purchase of a Target Interest by AY shall be completed pursuant to a written purchase and sale agreement negotiated, agreed upon and executed by the Parties during the Negotiation Period (a “Definitive Agreement”).

(b) Notwithstanding any other provision of this Agreement, the consummation of any Transfer to any AY Company pursuant to the terms of this Agreement shall be subject to obtaining all Governmental Approvals and material Third Party consents or approvals reasonably required in connection therewith. Following execution of a Definitive Agreement, each Party shall use its commercially reasonable efforts to obtain all such approvals and consents required to be obtained by such Party or its Affiliates and shall reasonably cooperate with all such efforts by any other Party or any Affiliate thereof.

(c) Unless otherwise agreed by the Parties, any Transfer of a Target Interest to any AY Company pursuant to the terms of this Agreement shall be consummated on or prior to the later of (i) ninety (90) days following the execution of the Definitive Agreement for such Transfer; and (ii) ten (10) Business Days following the satisfaction of all conditions thereto, including the receipt of all Governmental Approvals, consents and approvals reasonably required by either Party in connection with such Transfer.

(b) Notwithstanding Clause 3.1(a), in the event that, during the Negotiation Period for a Target, AY delivered a Binding Offer for such Target Interest to AAGES then, for a period of thirty (30) months following the expiration (or earlier termination by AY) of such Negotiation Period (a “Restricted Transfer Period”) no AAGES Company shall Transfer such Target Interest to any Person for an aggregate Equity Purchase Price that is less than 105% (or, in the case of a ROFO Interest in a CanUSA ROFO Asset, 100%) of the last Equity Purchase Price offered by AY during the Negotiation Period pursuant to a Binding Offer and otherwise upon terms and conditions that, when taken together, are not materially less favorable to the AAGES Company than those that were last proposed by AY in a Binding Offer.

RIGHT OF FIRST OFFER

2.1 Exclusive Right of First Offer.

(a) Pursuant to this Agreement, AQN grants to AY an exclusive right of first offer for any ROFO Interest in accordance with the terms and conditions set forth in this Agreement, subject only to Existing Rights. Other than Existing Rights, AQN represents and warrants that it has not and will not grant to any other Person any other right of first offer, right of first refusal or other similar agreements in relation to any ROFO Interests, unless (a) such rights will not be exercisable with respect to any Transfer (or proposed Transfer) of such ROFO Interests to AY pursuant to this Agreement, or (b) AY has consented thereto in writing.

(b) AQN hereby confirms that AQN is supportive of AY in its growth aspirations in Canada and the United States and that it intends to periodically discuss with AY the possibility of offering, for sale to AY, interests in certain assets owned by AQN Companies in Canada or the United States; provided that, for the avoidance of doubt, (i) such assets do not constitute ROFO Assets except to such extent as may be specifically agreed by AQN and AY in writing, and (ii) the decision as to whether or not to proceed with any such transaction shall be in the sole discretion of AQN.

2.2 Consideration. The rights granted to AY in this Agreement are granted in exchange for a Fee paid by any AY Company in exchange for any ROFO Interest, which shall be paid by or on behalf of such AY Company, simultaneously with the closing of the Transfer of such ROFO Interest to an AY Company, to a bank account designated by the AQN Company that is the seller of such ROFO Interest.

2.3 Restrictions on Negotiations; Status Meetings.

(a) AQN shall procure that no AQN Company nor any representative or agent thereof (including any AAGES Company) shall solicit offers from, or negotiate or enter into any agreement with, any Person for the Transfer of a ROFO Asset, ROFO Entity or ROFO Interest (other than a Permitted Transfer or Exempt Transfer) unless AQN first delivers a Transaction Notice to AY and complies with the terms and provisions of this Article 2 with respect to such ROFO Interest.

2.4 Transaction Notice.

(a) Prior to any AQN Company soliciting offers from, or negotiating or entering into any agreement with, any Person for the Transfer of any ROFO Interest or related ROFO Asset or ROFO Entity (other than a Permitted Transfer or Exempt Transfer), AQN shall deliver to AY written notice of its intent to commence the Negotiation Period with respect to such ROFO Interest, together with copies of (or details for AY to obtain immediate electronic access to) the Transfer Information (as defined herein) related to such ROFO Interest and the related ROFO Asset and ROFO Entities (collectively, a “Transaction Notice”).

(c) For the avoidance of doubt, a Target Interest shall include all direct and indirect Financial Interests of AQN in the applicable Target Asset, but the Target Entities shall include only those entities related to the Target Asset (including any financing thereof), such that upon a Transfer of such Target Interest to an AY Company, such AY Company shall not thereby directly or indirectly acquire any assets or companies, or directly or indirectly acquire or assume any liabilities, that are unrelated to such Target Asset.

(d) In the event that AQN has not previously delivered to AY a Transaction Notice with respect to its direct or indirect interest in a particular ROFO Asset, AY may deliver written notice to AQN (a “Transaction Notice Request”) at any time within twelve (12) months following the date on which such ROFO Asset becomes an Operating Asset, requesting that AQN commence good faith negotiations with respect to a Transfer of such ROFO Interest to AY. Within sixty (60) days following delivery of a Transaction Notice Request, AQN shall deliver to AY either:

(i) written notice confirming that AQN has no present intention to Transfer such ROFO Interest (other than pursuant to a Permitted Transfer or Exempt Transfer), in which case AQN shall not be obligated to deliver a Transaction Notice to AY except as provided in Clause 2.4(a) and, until such time as such a Transaction Notice is delivered pursuant to in Clause 2.4(a), the provisions of Clauses 2.5, 2.6 and 2.7 shall not apply; or

(ii) a Transaction Notice pursuant to Clause 2.4(a) with respect to such ROFO Interest and, thereupon, the remaining provisions of this Article 2 shall apply thereto; provided, however, that the foregoing shall not obligate AQN to sell or otherwise dispose of all or any portion of the applicable ROFO Interest to any AY Company or any other Person.

2.5 Transfer Information. As part of any Transaction Notice, AQN shall make available to AY, electronically or in hard copy, the following information that is then in the possession of or reasonably available to AQN relating to the applicable Target, all as determined in good faith by AQN (“Transfer Information”), without limiting AY’s right under Clause 2.6(b) to such additional information as may be reasonably requested by AY during the Negotiation Period:

(a) a reasonably detailed description of the Target Interest, the Target Entities, and the Target Asset;

(b) a non-binding indicative target price for the sale of the Target Interest;

(d) all material tax information relating to the Target Interest, the Target Entities and the Target Asset including, but not limited to, all tax returns, tax inspections and tax claims;

(g) the most recent version of (and any updates to) the reports and studies, if any, prepared by (i) an independent engineer, including (to the extent then reasonably capable of determination) assessment of the extent to which the Target Asset has been built in accordance with applicable specifications and industry standards, and the extent to which the Target Asset can be expected to deliver the expected performance, and (ii) any geotechnical engineer, environmental consultant, or other consultant with respect to the Target Asset, in the case of each of the foregoing prepared on behalf of or for any AQN Company or, to the extent available to AQN, on behalf of or for any Financing Party;

(b) Notwithstanding Clause 3.1(a), in the event that, during the Negotiation Period for a Target, AY delivered a Binding Offer for such Target Interest to AQN then, for a period of thirty (30) months following the expiration (or earlier termination by AY) of such Negotiation Period (a “Restricted Transfer Period”) no AQN Company shall Transfer such Target Interest to any Person for an aggregate Equity Purchase Price that is less than 105% of the last Equity Purchase Price offered by AY during the Negotiation Period pursuant to a Binding Offer and otherwise upon terms and conditions that, when taken together, are not materially less favorable to the AQN Company than those that were last proposed by AY in a Binding Offer.

(C) as reasonably required to give effect to a tax equity or other specialized financing transaction with an experienced provider of such specialized financing;

(iii) any Transfer of any ROFO Interest by any AQN Company to any AAGES Company if such AAGES Company is then a party to (or is an Affiliate of a party to) the AAGES ROFO Agreement and agrees in writing for the benefit of AY that such ROFO Interest (together with any ROFO Interest previously Transferred to any AAGES Company pursuant to Clause 3.2(a)(iii)) will immediately upon such Transfer be subject to and bound by the terms of such AAGES ROFO Agreement.

AY agrees to execute such documents and take such other action as may be reasonably requested by AQN to confirm and give full effect to the foregoing.

(b) AY hereby agrees that any AAGES Company may at any time Transfer any Facility or interest therein to any AQN Company, and that any rights or restrictions otherwise arising in connection with such Transfer under the AAGES ROFO Agreement are hereby waived; provided, that, subject to Clause 4.2(c), or unless such Facility is located in the United States or Canada (or any territory of either), upon and following such Transfer such Facility or interest therein shall be subject to the applicable rights and restrictions set forth in this Agreement until such rights and restrictions expire or terminate in accordance with the terms of this Agreement. AY agrees to execute such documents and take such other action as may be reasonably requested by AQN to confirm and give full effect to the foregoing.

(c) This Agreement shall not apply to any direct or indirect interest of any AQN Company in any Facility, nor to any direct or indirect Transfer thereof by any AQN Company:

(i) if such interest is held through one or more AAGES Companies (except as provided in Clause 3.2(a)(iii));

(ii) if such interest is Transferred by any AAGES Company to any AQN Company (A) in accordance with Clause 3.1 of the AAGES ROFO Agreement, or (B) upon or following the expiration of the rights of AY under the AAGES ROFO Agreement with respect to such interest, unless otherwise expressly agreed in writing by AQN for the benefit of AY; or

(iii) if such interest is Transferred by any AAGES Company to any AQN Company and AQN has expressly agreed in writing for the benefit of AY that such interest will be subject to the AAGES ROFO Agreement.

4.3 Existing Third Party Rights.

(b) To the extent that there is any conflict between the terms of an Existing Right and the terms of this Agreement, the terms of such Existing Right shall prevail. Notwithstanding the foregoing, AQN shall, and shall cause each AQN Company to, use commercially reasonable efforts (without the incurrence of financial burden) to exempt from any Existing Right any Transfer of a ROFO Interest to any AY Company pursuant to this Agreement.
