4.9 The Corporation will prepare a final term sheet containing only a description of the Offering, in a form approved by the Underwriters and attached as Exhibit B hereto, and will file such term sheet with the SEC pursuant to Rule 433(d) under the 1933 Act within the time required by such rule (such term sheet, the “Final Term Sheet”). Any such Final Term Sheet is an Issuer Free Writing Prospectus for purposes of this Agreement.

4.10 The Corporation represents that it has not made, and agrees that, unless it obtains the prior written consent of the Representatives, it will not make, any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the 1933 Act) required to be filed by the Corporation with the SEC or retained by the Corporation under Rule 433 under the 1933 Act; provided that the prior written consent of the Representatives shall be deemed to have been given in respect of any Issuer Free Writing Prospectus included in Annex I to this Agreement. Any such free writing prospectus consented to or deemed to be consented to by the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Corporation agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, and (ii) has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 under the 1933 Act applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the SEC, legending and record keeping. The Corporation consents to the use by any Underwriter of a free writing prospectus that (a) is not an “issuer free writing prospectus” as defined in Rule 433 under the 1933 Act, and (b) contains only (i) information describing the preliminary terms of the offering of Shares, (ii) information permitted by Rule 134 under the 1933 Act, (iii) pricing information or (iv) information that describes the final terms of the Offering and that is included in the Final Term Sheet of the Corporation contemplated in Section 4.9. From the date of commencement of the distribution of the Shares to the date such distribution ceases, each Underwriter will not make use of any “bluesheet” or provide any other marketing materials in respect of the Shares without the approval of the Corporation and Morgan Stanleyand no “standard term sheet” (as defined in NI 41-101) in respect of the Shares will be provided by them to any potential investors of the Shares without the approval of the Corporation and Morgan Stanley. For clarity, the Corporation and Morgan Stanley, on behalf of the Underwriters, have approved the use of standard term sheets (as defined in NI 41-101) dated October 9, 2019 and October 10, 2019, each in respect of the Offering.

4.11 The Corporation agrees that it has not and will not distribute during the term of this Agreement, any “marketing materials” in connection with the offering and sale of the Shares other than the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus reviewed and consented to by the Underwriters, provided that the Underwriters, severally and not jointly, covenant with the Corporation not to take any action that would result in the Corporation being required to file with the Canadian Securities Regulators any “marketing materials” that otherwise would not be required to be filed by the Corporation, but for the action of the Underwriters. For clarity, the Corporation and Morgan Stanley, on behalf of the Underwriters, have approved the template version (as such term is defined in NI 41-101) of the investor presentation for the Offering dated October 7, 2019 (in the English and French languages), as incorporated by reference in the Canadian Prospectus Supplement.

14

4.12 The Corporation agrees to pay the required Canadian Securities Regulators and SEC filing fees relating to the Shares and any other fees required by the Canadian Securities Regulators within the time required by and in accordance with Applicable Securities Laws.

4.13 The Corporation has not taken and will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Canadian Securities Laws, stabilization or manipulation of the price of the Shares to facilitate the sale or resale of the Shares, except for purchases by insiders of the Corporation in accordance with relief obtained or to be obtained by the Corporation from the requirements of OSC Rule 48-501 – Trading during Distributions, Formal Bids and Share Exchange Transactions, and the Corporation has not taken and will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the 1934 Act, stabilization or manipulation of the price of the Shares to facilitate the sale or resale of the Shares.

4.14 The Corporation shall apply the net proceeds received by it from the sale of the Shares substantially in the manner described under the caption “Use of Proceeds” in the Preliminary Prospectus and the Prospectus.

4.15 The Corporation shall use its best efforts to ensure that members of management are available to provide assistance to the Underwriters, as requested by the Underwriters, with respect to the marketing of the Shares.

4.16 The Corporation shall use commercially reasonable efforts to apply for the Shares to be listed and posted for trading on the NYSE and the TSX at the Time of Closing.

SCHEDULE B

INDEMNIFICATION

Capitalized terms used but not defined in this Schedule B shall have the meanings assigned to them in the Agreement to which this Schedule is attached.

1. Indemnity

(a) Indemnity

Algonquin Power & Utilities Corp. (the “Indemnitor”) hereby agrees to indemnify and hold harmless the Indemnified Parties from and against all liabilities, claims, losses (other than loss of profits), reasonable costs, damages and reasonable expenses (including, without limitation any legal fees or other expenses reasonably incurred by the Underwriters in connection with defending or investigating any such action or claim, securityholder or derivative actions, arbitration proceedings or otherwise) (a “Claim”) in any way caused by, or arising directly or indirectly from, or in consequence of:

(i) any information or statement (except any statement relating solely to such Underwriter or Underwriters which has been provided in writing to the Corporation by or on behalf of such Underwriter or Underwriters through the Representatives specifically for inclusion therein) contained in the Agreement, Registration Statement, Disclosure Package, Prospectus, Issuer Free Writing Prospectus, Corporation Additional Written Communication,any Supplementary Material, or any Prospectus Amendments thereto, supplements or in any certificate of the Corporation delivered pursuant to the Agreement which, at the time and, other than with respect to the Registration Statement, in the light of the circumstances under which it was made, contains or is alleged to contain a misrepresentation or untrue statement of a material fact;

(ii) any omission or alleged omission to state in the Registration Statement, Disclosure Package, Prospectus, Issuer Free Writing Prospectus, Corporation Additional Written Communication, any Supplementary Material, or any Prospectus Amendments thereto, supplements or in any certificate of the Corporation delivered pursuant to the Agreement, any material fact (except any fact relating solely to such Underwriter or Underwriters which has been provided in writing to the Corporation by or on behalf of such Underwriter or Underwriters through the Representatives specifically for inclusion therein) regarding the Corporation and its operations and affairs that is necessary to make any statement therein not misleading in light of the circumstances in which it was made;

(iii) any order made or enquiry, investigation or proceedings commenced or threatened by any securities commission or other competent authority based upon any untrue statement or omission or alleged untrue statement or alleged omission or any misrepresentation or alleged misrepresentation (except a statement or omission or alleged statement or omission regarding facts relating solely to such Underwriter or Underwriters which has been provided in writing to the Corporation by or on behalf of such Underwriter or Underwriters through the Representatives specifically for inclusion therein) in the Registration Statement, Disclosure Package, Issuer Free Writing Prospectus, Corporation Additional Written Communication,Prospectus, any Supplementary Materials, or any Prospectus Amendments or supplements thereto or based upon any failure to comply with Applicable Securities Laws (other than any failure or alleged failure to comply by any of the Underwriters), preventing or restricting the trading in or the sale or distribution of the Shares;

B-1

(iv) the non-compliance or alleged noncompliance by the Corporation with any of Applicable Securities Laws, including, in the case of the Corporation, the Corporation’s non-compliance with any statutory requirement to make any document available for inspection; or

(v) any breach by the Corporation of its material representations, warranties, covenants or obligations to be complied with under the Agreement.

This indemnity shall cease to be available to an Indemnified Party if (i) a court of competent jurisdiction in a final judgment in which such Indemnified Party is named as a party determines that the Claim in respect of which indemnification is sought is a result of or arises out of the gross negligence or willful misconduct of such Underwriter or Underwriters (provided that, for greater certainty, the Corporation and the Underwriters agree that they do not intend that any failure by the Underwriters to conduct such reasonable investigation as necessary to provide the Underwriters with reasonable grounds for believing the Registration Statement, Disclosure Package, Prospectus, Issuer Free Writing Prospectus, Corporation Additional Written Communication, any Supplementary Material, or any Prospectus Amendments contained no misrepresentation shall constitute, “gross negligence” or “willful misconduct” for purposes of this Section 1 or otherwise disentitle the Underwriters from indemnification hereunder); or (ii) a copy of the Prospectus (as then amended or supplemented, if the Corporation shall have furnished any amendments or supplements thereto) was not sent or given by or on behalf of the Underwriters to a person asserting any such losses, claims, damages or liabilities, but only (x) if required by law so to have been delivered by the Underwriters to such person, at or prior to the written confirmation of the sale of the Shares to such person, and (y) if the Prospectus (as so amended or supplemented) delivered by the Underwriters a reasonable amount of time in advance of such confirmation would have cured the defect giving rise to such losses, claims, damages or liabilities. In such event, such Underwriter or Underwriters shall reimburse any funds advanced by the Corporation to such Underwriter or Underwriters pursuant to the indemnification contained in this Schedule B in respect of such Claim and thereafter this indemnity shall cease to apply to such Underwriter or Underwriters in respect of such Claim.

The Corporation hereby acknowledges that the only information furnished to the Corporation by any Underwriter through the Representatives expressly for use in the Registration Statement, any Corporation Additional Written Communication, any Issuer Free Writing Prospectus, the Preliminary Prospectus, or the Prospectus (or any amendment or supplement thereto) are the statements set forth in the first paragraph under the caption “Plan of Distribution—Commissions and Discounts,” and the first and second paragraphs under the caption “Plan of Distribution—Price Stabilization, Short Positions,” each in the Preliminary Prospectus and the Prospectus.

B-2

(b) Notification of Claims

If any Claim is asserted against any Indemnified Party, such Indemnified Party will notify the Corporation as soon as possible of the nature of such Claim (but the omission so to notify the Corporation of any potential Claim shall not relieve the Corporation from any liability which it may have to any Indemnified Party and any omission so to notify the Corporation of any actual Claim shall affect the Corporation’s liability only to the extent that it is prejudiced as a proximate result of that failure). Subject to subsection 1(d), the Corporation shall be entitled to participate in and, to the extent that it shall wish, to assume the defense of any suit brought to enforce such Claim; provided, however, that the defense shall be conducted through legal counsel acceptable to such Indemnified Party, acting reasonably, that no settlement of any such Claim or admission of liability may be made by the Corporation or such Indemnified Party without the prior written consent of the other parties, acting reasonably, and the Corporation shall not be liable for any settlement of any such Claim unless it has consented in writing to such settlement. The Corporation shall not settle any Claim, or compromise a consent to any judgment unless such settlement, compromise or judgment (i) includes an unconditional release of such Indemnified Party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of such Indemnified Party.

(c) Right of Indemnity in Favor of Others

With respect to any Indemnified Party who is not a party to the Agreement, the Indemnified Parties who are party to the Agreement shall obtain and hold the rights and benefits of this Section 1 of this Schedule Bin trust for and on behalf of such Indemnified Party.

(d) Retaining Counsel

In any Claim, the Indemnified Party shall have the right to retain other counsel to act on its behalf, provided that the reasonable fees and disbursements of such counsel shall be paid by such Indemnified Party unless (i) the Corporation fails to assume the defense of such suit on behalf of such Indemnified Party within 10 days of receiving written notice of such suit; (ii) the Corporation and such Indemnified Party shall have mutually agreed to the retention of the other counsel; or (iii) the named parties to any such Claim (including any added third or impleaded party) include such Indemnified Party and the Corporation and such Indemnified Party shall have been advised by counsel that the representation of all parties by the same counsel would be inappropriate due to the actual or potential differing interests between them, including the potential availability of one or more legal defenses to such Indemnified Party which are different from or in addition to those available to the other parties or the potential for a conflict to exist between the Corporation and such Indemnified Party. In no event shall the Corporation be liable to pay the fees and disbursements of more than one firm of separate counsel for all Indemnified Parties and, in addition, one firm of local counsel in each applicable jurisdiction.

B-3

2. Contribution

(a) Contribution by the Corporation

In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in Section 1 of this Schedule B is unavailable, in whole or in part, for any reason to an Indemnified Party in respect of any Claim, the Corporation (the “Indemnifier”) and the applicable Underwriter or Underwriters shall contribute to the amount paid or payable (or, if such indemnity is unavailable only in respect of a portion of the amount so paid or payable, such portion of the amount so paid or payable) by the Corporation as a result of such Claim in such proportion as is appropriate to reflect the relative benefits received by the Corporation on the one hand and the applicable Underwriter or Underwriters on the other hand from the offering of the Shares; or if this allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Corporation on the one hand and the applicable Underwriter or Underwriters on the other hand in connection with the information, statement, omission, misrepresentation, order, inquiry, investigation or other matter or thing referred to in Section 1 of this Schedule B which resulted in such Claim, as well as any other relevant equitable considerations.

The relative benefits received by the Corporation on the one hand and the applicable Underwriter or Underwriters on the other hand shall be deemed to be in the same respective proportions as the total proceeds (net of the underwriting commission (or discount, as the case may be), but before deducting expenses (to the extent that such expenses are payable by the Corporation pursuant to Section 3 of this Schedule B)) received by the Corporation from the issue and sale of the Shares, and the total underwriting commission (or discount received, as the case may be) by the applicable Underwriter or Underwriters, in each case, as set out in the table on the cover page of the Prospectus bear to the aggregate initial public offering price of the Shares on the cover page of the Prospectus. The relative fault of the Corporation on the one hand and of the applicable Underwriter or Underwriters on the other shall be determined by reference to, among other things, whether the information, statement, omission, misrepresentation, order, inquiry, investigation or other matter or thing referred to in Section 1 of this Schedule B which resulted in such Claim relates to information supplied by or steps or actions taken or done by or on behalf of the Corporation or to information supplied by or steps or actions taken or done by or on behalf of the applicable Underwriter or Underwriters and the relative intent, knowledge, access to information and opportunity to correct or prevent such statement, omission, misrepresentation, order, inquiry, investigation or other matter or thing referred to in Section 1 of this Schedule B. The amount paid or payable by an Indemnified Party as a result of the Claim referred to above shall include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such Claim, whether or not resulting in any such action, suit, proceeding or claim. The Corporation and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 2 were determined by any method of allocation which does not take into account the equitable considerations referred to immediately above.

A person who is engaged in any fraud, fraudulent misrepresentation or gross negligence shall not, to the extent that a court of competent jurisdiction in a final judgment determines that the Claim was caused by that activity, be entitled to claim contribution therefor from any person who has not also been determined by a court of competent jurisdiction in a final judgment to have engaged in that fraud, fraudulent misrepresentation or gross negligence.

B-4

(b) Right of Contribution in Addition to Other Rights

The rights to contribution provided in this Section 2 shall be in addition to and not in derogation of any other right to contribution which the Underwriters may have by statute or otherwise at law.

(c) Calculation of Contribution

In the event that a court of competent jurisdiction in a final judgment determines that an Indemnifier is entitled to contribution from an Underwriter or Underwriters under the provisions of any statute or at law, the Indemnifier shall be limited to contribution in an amount not exceeding the lesser of:

(i) the portion of the full amount of the loss or liability giving rise to such contribution for which the applicable Underwriter or Underwriters are responsible, as determined in subsection 2(a) of this Schedule B, and

(ii) the amount of the underwriting commissions actually received by the applicable Underwriter or Underwriters from the Corporation under the Agreement; provided that no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter or Underwriters in connection with the Shares underwritten by it.

(d) Notice of Claim for Contribution

Notification to the Corporation of a Claim pursuant to subsection 1(b) of this Schedule B shall be deemed to also constitute notice to the Corporation that a claim for contribution by the Underwriters may arise and omission to so notify shall have similar effect.

(e) Right of Contribution in Favor of Others

The Corporation hereby acknowledges and agrees that, with respect to paragraphs 1 and 2 of this Schedule B, each of the Underwriters are contracting on their own behalf and as agents for their affiliates, subsidiaries, directors, officers, employees, agents and control persons (collectively, the “Beneficiaries”). In this regard the Underwriters shall act as trustees for the Beneficiaries of the Corporation’s covenants under paragraphs 1 and 2 of this Schedule B with respect to the Beneficiaries and accept these trusts and shall hold and enforce the covenants on behalf of the Beneficiaries. The Underwriters’ respective obligations to contribute pursuant to this Section 2 are several in proportion to the amounts set forth opposite their names in Schedule A of the Agreement and not joint.

B-5

3. Severability

If any provision of Section 1 or 2 of this Schedule B is determined to be void or unenforceable in whole or in part, it shall be deemed not to affect or impair the validity of any other provision of the Agreement and such void or unenforceable provision shall be severable from the Agreement.

Ladies and Gentlemen:

The undersigned understands that Morgan Stanley & Co. LLC (“Morgan Stanley”) and Wells Fargo Securities, LLC (together with Morgan Stanley, the “Representatives”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Algonquin Power & Utilities Corp., a Canadian corporation (the “Corporation”), providing for the public offering (the “Public Offering”) by the several underwriters named in Schedule A to the Underwriting Agreement (the “Underwriters”) of common shares in the capital of the Corporation (the “Common Shares”).

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of Morgan Stanley on behalf of the Underwriters, it will not, and will not publicly disclose an intention to, during the period commencing on the date hereof and ending 30 days after the date of the final prospectus (the “Restricted Period”) relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Shares beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for Common Shares or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Shares, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Shares or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) transactions relating to Common Shares or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made in connection with subsequent sales of Common Shares or other securities acquired in such open market transactions, (b) transfers of Common Shares or any security convertible into Common Shares as a bona fide gift, provided that in the case of any transfer or distribution pursuant to clause (b), (i) each donee shall sign and deliver a lock‑up agreement substantially in the form of this agreement and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of Common Shares, shall be required or shall be voluntarily made during the Restricted Period, or (c) facilitating the establishment of a trading plan on behalf of a shareholder, officer or director of the Corporation pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Common Shares, provided that (i) such plan does not provide for the transfer of Common Shares during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Corporation regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Common Shares may be made under such plan during the Restricted Period. In addition, the undersigned agrees that, without the prior written consent of Morgan Stanley on behalf of the Underwriters, it will not, during the Restricted Period, make any demand for or exercise any right with respect to, the registration of any Common Shares or any security convertible into or exercisable or exchangeable for Common Shares. The undersigned also agrees and consents to the entry of stop transfer instructions with the Corporation’s transfer agent and registrar against the transfer of the undersigned’s Common Shares except in compliance with the foregoing restrictions.
