Each Shareholder shall vote all Voting Shares over which such Shareholder has voting control and shall take all other necessary or desirable actions within such Shareholder’s control (including in its capacity as shareholder of the Company or otherwise, and whether at an annual or special meeting of the Shareholders or by written resolution in lieu of a meeting) to elect to the Board any individual designated by an Initial Shareholder under Section 2.01(a).

(c)

Each Initial Shareholder shall have the right at any time to remove (with or without cause) any Director designated by such Initial Shareholder for election to the Board and each other Shareholder shall vote all Voting Shares over which such Shareholder has voting control and shall take all other necessary or desirable actions within such Shareholder’s control (including in its capacity as shareholder or director of the Company or otherwise, and whether at an annual or special meeting of the Shareholders or by written resolution in lieu of a meeting) to remove from the Board any individual designated by such Initial Shareholder that such Initial Shareholder desires to remove under this Section 2.01.

The Company shall advance moneys to a Person described above for the costs, charges and expenses of a proceeding referred to above, provided such Person shall repay the moneys if the Person does not fulfil the condition of the following paragraph.

Notwithstanding the preceding paragraph, the Company shall not indemnify a Person identified in the preceding paragraph, unless such Person:

Section 3.02 Exercise of Exchange Provisions. APCo may exercise the Exchange Options or Atlantica may exercise the Class C Exchange Option by providing a written notice to each of the other parties hereto. Forthwith following the exercise of the Exchange Options, Atlantica shall cause its transfer agent to, issue and deliver to APCo from treasury, in exchange for the certificates evidencing the Class C Common Shares and Class II Common Shares, as the case may be, a certificate, or other evidence of ownership, registered in the name of APCo (or as APCo may otherwise direct) representing the Atlantica Shares issued in exchange for the Class C Common Shares and Class II Common Shares, as the case may be.

Section 3.03 Obligations of Atlantica. Atlantica covenants and agrees that for so long as the Exchange Options are exercisable, it shall reserve and there shall remain unissued out of its authorized capital a sufficient number of Atlantica Shares to satisfy the obligation herein provided, as such right may be adjusted. Atlantica further covenants and agrees that while the Exchange Options are exercisable, Atlantica shall (a) comply with the securities legislation applicable to it in order that Atlantica not be in default of any requirements of such legislation; (b) use its commercially reasonable best efforts to do or cause to be done all things necessary to preserve and maintain its corporate existence; and (c) at its own expense expeditiously use its commercially reasonable best efforts to obtain the listing of the Atlantica Shares on each stock exchange or over-the-counter market on which its ordinary shares of common stock may be listed from time to time. All Atlantica Shares which shall be issued upon the exercise of the Exchange Options herein provided for, shall be issued as fully paid and non-assessable shares and the holders thereof shall not be liable to Atlantica or its creditors in respect thereof. Note:

Section 3.04 Adjustment. If, following the issuance of the Class C Common Shares or Class II Common Shares, any action is taken that results in a change to the Atlantica Shares (or other securities or assets into which the Class C Common Shares or Class II Common Shares may be exchanged from to time) the holder of the Class C Common Shares and Class II Common Shares shall be entitled, on the exchange of the Class C Common Shares and Class II Common Shares, to receive the same (or economically equivalent) consideration as they would have received had they been a holder of Atlantica Shares (or other securities or assets into which the Class C Common Shares or Class II Common Shares may be exchange from time to time) at the time such action was taken.

Section 3.05 Atlantica Shareholders Agreement. Subject to the following sentence, notwithstanding anything to the contrary herein, to the extent that there is an inconsistency between this Agreement and the provisions of the shareholders agreement dated March 5, 2018, as amended from time to time, between Algonquin Power & Utilities Corp., Abengoa-Algonquin Global Energy Solutions B.V. and Atlantica (the “AY Shareholders Agreement”), the terms of the AY Shareholders Agreement shall govern.

Section 3.06 Limitation on Exchange. Notwithstanding anything to the contrary herein, in no event shall APCo be required or permitted, directly or indirectly, to subscribe or exchange shares for securities of Atlantica that would cause APCo and/or its Affiliates to hold more than 50% of the total voting rights attached to the Atlantica Shares. To the extent that any exchange contemplated hereby would cause APCo and/or its Affiliates to hold more than 50% of the total voting rights attached to the Atlantica Shares, such transaction shall be deemed to be null and void without any further action by any party.

The provisions of Section 4.01(a) and Section 4.02, shall not apply to any Transfer by any Shareholder of any of its Shares to a Permitted Transferee.

(c)

In addition to any legends required by Applicable Law, each certificate representing the Shares shall bear a legend substantially in the following form:

“The shares represented by this certificate are subject to the provision of a Shareholders’ Agreement, which Shareholders’ Agreement contains restrictions on the right of the holder to sell, assign, transfer, dispose of, donate or otherwise deal with the shares represented by this certificate. Notice of the terms and conditions of the Shareholders’ Agreement is hereby given.”

(d)

Prior notice shall be given to the Company by the transferor of any Transfer (whether or not to a Permitted Transferee) of any Shares. Before consummation of any Transfer by any Shareholder of any of its Shares, such party shall cause the transferee thereof to execute and deliver to the Company a Joinder Agreement and agree to be bound by the terms and conditions of this Agreement. Upon any Transfer by any Shareholder of any of its Shares in accordance with the terms of this Agreement, the transferee thereof shall be substituted for, and shall assume all the rights and obligations under this Agreement of, the transferor thereof.

(e)

Notwithstanding any other provision of this Agreement, each Shareholder agrees that it will not, directly or indirectly, Transfer any of its Shares, except as permitted under the Securities Act and other applicable provincial or territorial securities laws, and then, if requested by the Company, only upon delivery to the Company of an opinion of counsel in form and substance satisfactory to the Company to the effect that such Transfer may be effected without filing a preliminary prospectus and a prospectus under the Securities Act (or other applicable provincial or territorial legislation). In any event, the Board may refuse the Transfer to any Person if such Transfer would have a material adverse effect on the Company as a result of any regulatory or other restrictions imposed by any Governmental Authority.

(f)

Any Shareholder and any Affiliate thereof shall have the right to Encumber:

(i)

exclusively the economic rights (and not, for the avoidance of doubt, the voting rights) attached to or included in any Shares, and

(ii)

any direct or indirect interest of such Shareholder’s parent in such Shareholder,

in each case without the consent of any other Shareholder and for any purposes, including as security for any present or future indebtedness of such Shareholder or any Affiliate thereof, provided, however, that any Transfer of any Shares, in any case as a result of foreclosure or other exercise of remedies with respect to any such Encumbrance shall be subject to the other provisions in this ARTICLE IV.

(g)

Any Transfer or attempted Transfer of any Shares in violation of this Agreement shall be null and void, no such Transfer shall be recorded on the Company’s books and the purported transferee in any such Transfer shall not be treated (and the purported transferor shall continue be treated) as the owner of such Shares for all purposes of this Agreement.

Section 4.02 Right of First Refusal

(a)

If at any time a Shareholder (such Shareholder, an “Offering Shareholder”) receives a bona fide offer from any Third Party Purchaser to purchase all or any portion of the Shares (the “Offered Shares”) owned by the Offering Shareholder and the Offering Shareholder desires to Transfer the Offered Shares (other than Transfers that are permitted by Section 4.01(b)), then the Offering Shareholder must first make an offering of the Offered Shares to each other Shareholder (each such Shareholder, an “ROFR Rightholder”) in accordance with the provisions of this Section 4.02.

(b)

The Offering Shareholder shall, within five Business Days of receipt of the offer from the Third Party Purchaser, give written notice (the “Offering Shareholder Notice”) to the Company and the ROFR Rightholders stating that it has received a bona fide offer from a Third-Party Purchaser and specifying:

(i)

the number of Offered Shares to be Transferred by the Offering Shareholder;

(ii)

the identity of the Third-Party Purchaser;

(iii)

the per share purchase price and the other material terms and conditions of the Transfer, including a description of any non-cash consideration in sufficient detail to permit the valuation thereof; and

(iv)

the proposed date, time and location of the closing of the Transfer, which shall not be less than 60 days from the date of the Offering Shareholder Notice.

The Offering Shareholder Notice shall constitute the Offering Shareholder’s offer to Transfer the Offered Shares to the ROFR Rightholders, which offer shall be irrevocable until the end of the ROFR Notice Period.

(c)

By delivering the Offering Shareholder Notice, the Offering Shareholder represents and warrants to the Company and to each ROFR Rightholder that: (i) the Offering Shareholder has the entire right, title and interest in and to the Offered Shares; (ii) the Offering Shareholder has all the corporate power and capacity and has taken all necessary action to Transfer such Offered Shares as contemplated by this Section 4.02; and (iii) the Offered Shares are free and clear of any and all Encumbrances other than those arising as a result of or under the terms of this Agreement.

(d)

Upon receipt of the Offering Shareholder Notice, each ROFR Rightholder shall have 10 Business Days (the “ROFR Notice Period”) to elect to purchase all (and not less than all) of the Offered Shares by delivering a written notice (a “ROFR Notice”) to the Offering Shareholder and the Company stating that it offers to purchase such Offered Shares on the terms specified in the Offering Shareholder Notice. Any ROFR Notice shall be binding upon delivery and irrevocable by the applicable ROFR Rightholder. If more than one ROFR Rightholder delivers a ROFR Notice, each such ROFR Rightholder (the “Purchasing Shareholder”) shall be allocated the number of shares equal to the product of (x) the total number of Offered Shares and (y) a fraction determined by dividing (A) the number of Shares owned by such Purchasing Shareholder as of the date of the Offering Shareholder Notice, by (B) the total number of Shares owned by all of the Purchasing Shareholders as of such date.

(e)

Each ROFR Rightholder that does not deliver a ROFR Notice during the ROFR Notice Period shall be deemed to have waived all such ROFR Rightholder’s rights to purchase the Offered Shares under this Section 4.02.

(f)

If no Shareholder delivers a ROFR Notice in accordance with Section 4.02(d), the Offering Shareholder may, during the 60 Business Day period immediately following the expiration of the ROFR Notice Period, which period may be extended for a reasonable time not to exceed 90 Business Days to the extent reasonably necessary to obtain any Government Approvals (the “Waived ROFR Transfer Period”), Transfer all of the Offered Shares to the Third Party Purchaser on terms and conditions no more favourable to the Third Party Purchaser than those set forth in the Offering Shareholder Notice. If the Offering Shareholder does not Transfer the Offered Shares within such period or, if such Transfer is not consummated within the Waived ROFR Transfer Period, the rights provided hereunder shall be deemed to be revived and the Offered Shares shall not be Transferred to the Third Party Purchaser unless the Offering Shareholder sends a new Offering Shareholder Notice in accordance with, and otherwise complies with, this Section 4.02.

(g)

Each Shareholder shall take all actions as may be reasonably necessary to consummate the Transfer contemplated by this Section 4.02, including entering into agreements and delivering certificates and instruments and consents as may be deemed necessary or appropriate.

(h)

At the closing of any Transfer under this Section 4.02, the Offering Shareholder shall deliver to the Purchasing Shareholder(s) the certificate or certificates representing the Offered Shares to be sold (if any), accompanied by executed forms of share transfers, against receipt of the purchase price therefor from such Purchasing Shareholder(s) by certified cheque or bank draft, or by wire transfer of immediately available funds.

(b)

Section 9.12 Dispute Resolution

(a)

To the fullest extent permitted by all then Applicable Law, in the event of the occurrence of any controversy, dispute or claim arising out of, in connection with, or in relation to the interpretation, performance or breach of this Agreement, any action taken by a party hereto pursuant to this Agreement, or otherwise arising out of or referable to the execution or performance of this Agreement (such controversy, dispute or claim being hereafter referred to in this Section 9.12 as the “Dispute”), such Dispute shall be determined by arbitration conducted in the City of Toronto in the Province of Ontario in accordance with the Arbitration Act, 1991, S.O. 1991, c. 17 and a party to this Agreement seeking arbitration of a Dispute shall so notify the others of them by notice in writing (an “Arbitration Notice”), which notice shall set out reasonable particulars of the Dispute in respect of which arbitration is so being sought. The parties intend that the provisions of this Section 9.12 to arbitrate be valid, enforceable and irrevocable..

(b)

The parties seeking arbitration in respect of a Dispute shall attempt to mutually agree on a single duly qualified arbitrator; provided that, if they cannot mutually agree on a single arbitrator within 20 days after the date on which the Arbitration Notice was sent by the party seeking arbitration, within 10 days following the end of such 20-day period, the parties seeking arbitration shall commence proceedings in a court of appropriate jurisdiction requesting the appointment of a single duly qualified arbitrator, which arbitrator must be a Person who is independent to each of the parties to this Agreement. The arbitrator which is mutually agreed to or appointed, as the case may be, in respect of a Dispute in accordance with the foregoing provisions of this Section 9.12(b) is hereinafter referred to in this Section 9.12 as the “Arbitrator”..

(c)

The Arbitrator shall conduct the arbitration proceedings in relation to the Dispute before such Arbitrator in accordance with the applicable rules of the Arbitration Act, 1991, S.O. 1991, c. 17 and, forthwith following the conclusion of such arbitration proceedings, the Arbitrator shall set forth his or her decision in writing (which decision shall enumerate in reasonable detail the basis therefor) and a copy of such decision shall be sent by the Arbitrator to each party to such arbitration.

(d)

To the fullest extent permitted by all then Applicable Law:

(i)

any controversy concerning whether a Dispute is an arbitrable matter or as to the interpretation or enforceability of this Section 9.12 shall be determined by the Arbitrator; and

(ii)

any judgment or award rendered by the Arbitrator shall be final, conclusive and binding (clerical errors and omissions and fraud only excepted) and judgment may be entered on any final, unappealable arbitration award by any provincial or federal court having jurisdiction thereof.

(e)

The parties hereto agree that the arbitration proceedings, as well as the fact such proceedings occur, shall be kept confidential by the parties hereto and may only be disclosed to their personal representatives and legal, accounting and other professional advisors or as required by all then Applicable Law and insofar as is necessary to confirm, correct, vacate or enforce the award. In the event of a breach of the preceding provisions of this Section 9.12(e), the Arbitrator is expressly authorized to assess damages and each of the parties hereto consents to the expansion of the scope of arbitration for such purpose. The pendency of any arbitration under this Section 9.12 shall not relieve any party hereto from the performance of its obligations under this Agreement. In no event, however, shall this Section 9.12 be deemed to preclude a party hereto from instituting legal action seeking relief in the nature of a restraining order, an injunction, an audit, the enforcement of any Encumbrances or the like in order to protect its rights pending the outcome of an arbitration hereunder and, if any party hereto shall resort to legal action for such types of relief, such party shall not be deemed to have waived its rights to cause such matter or any other matter to be referred to arbitration pursuant to this Section 9.12. The Arbitrator shall have authority in his sole, arbitrary, absolute and unfettered discretion to grant injunctive relief, award specific performance and impose sanctions upon any party to any such arbitration; provided that, no party to the arbitration may seek, and the Arbitrator shall not award, consequential, punitive or exemplary damages or indirect economic loss. The fees, expenses and charges of any such arbitration shall be allocated among the parties thereto in such manner as the Arbitrator shall determine acting reasonably.

Section 9.13 Equitable Remedies. Each party hereto acknowledges that the other parties hereto would be irreparably damaged in the event of a breach or threatened breach by such party of any of its obligations under this Agreement and hereby agrees that, in the event of a breach or a threatened breach by such party of any such obligations, each of the other parties hereto shall, in addition to any and all other rights and remedies that may be available to them in respect of such breach, be entitled to seek an injunction from a court of competent jurisdiction (without any requirement to post a bond or other security) granting such parties specific performance by such party of its obligations under this Agreement. If any party commences an action to enforce the covenants contained in this Agreement (or obtain any other remedy in respect of any breach thereof), the prevailing party in the action shall be entitled to receive, in addition to all other damages to which it may be entitled, the costs incurred by such party in conducting the action, including reasonable legal fees, disbursements and charges.

Section 9.14 Language. The parties have required that this Agreement and all documents and notices resulting from it be drawn up in English. Les parties aux présents ont exigés que la présente convention ainsi que tous les documents et avis qui s’y rattachent ou qui en découleront soit rédigés en la langue anglaise.

Section 9.15 Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall be deemed to be one and the same agreement.
