LLC, other than (A) the Shares to be sold hereunder or issued in connection with the

the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Prospectus to comply with the Securities Act or the Exchange Act, as applicable, and the rules and regulations promulgated thereunder, or the Canadian Securities Laws, forthwith to prepare, file with the Commission and the Canadian Securities Commissions, in each case, to the extent required by law and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when the Time of Sale Prospectus is delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with such applicable law.

(g) If, during such period after the first date of the public offering of the Shares (or the filing of a Canadian Preliminary Prospectus) as in the opinion of counsel for the Underwriters the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus to comply with the Securities Act or the Exchange Act, as applicable, and the rules and regulations promulgated thereunder, or Canadian Securities Laws, forthwith to prepare, file with the Commission and the Canadian Securities Commissions, in each case, to the extent required by law, and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses you will furnish to the Company) to which Shares may have been sold by you on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with such applicable law.

(h) To endeavor to qualify the Shares for offer and sale under the securities or blue sky laws of such jurisdictions (that are required for the offer and sale) as you shall reasonably request, provided that, in connection therewith, the Company shall not be required to (i) qualify as a foreign corporation in any jurisdiction in which it would not otherwise be required to so qualify, (ii) file a general consent to service of process in any such jurisdiction or (iii) subject itself to taxation in any jurisdiction in which it would not otherwise be subject.

For the avoidance of doubt, the Company’s obligation to pay expenses under this Section 8 shall not include any obligation to pay underwriting commissions on any Additional Shares sold by Pattern Renewables. Pattern Renewables agrees to pay the fees, disbursements and expenses of counsel applicable to it and all fees and expenses of the Company in respect of any Additional Shares purchased by the Underwriters. It is understood, however, that, except as provided in this Section 8, and Sections 11, 12 and 14 hereof, the Underwriters will pay all stock transfer taxes on resale of any of the Shares by them.

(b) The provisions of this Section shall not supersede or otherwise affect any agreement that the Company and the PEG Parties may otherwise have for the allocation of such expenses among themselves.

9. Covenants of the Underwriters.

(a) Each Underwriter severally covenants with the Company that, without the prior consent of the Company and the Representatives, it has not made and will not take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of or used or referred to by such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of such Underwriter; any such free writing prospectus the use of which has been consented to by the Company and the Representatives is listed on Schedule II hereto.

(b) The Underwriters will be permitted to appoint, at their sole expense, other registered dealers or brokers as their agents to assist in the distribution of the Shares in the provinces and territories of Canada (a “Selling Firm”). The Underwriters shall, and shall require any Selling Firm, to comply with Canadian Securities Laws in connection with the distribution of the Shares and to offer the Shares for sale only in the provinces

and territories of Canada directly and through duly appointed Selling Firms upon the terms and conditions set forth in the Prospectus and this Agreement. The Underwriters shall, and shall require any Selling Firm to agree to, offer for sale and sell the Shares only in those jurisdictions where they may be lawfully offered by the Underwriters for sale or sold. Without limiting the generality of the foregoing, no Shares will be offered for sale or sold in any province or territory of Canada by any Canadian Underwriter or any Selling Firm unless such Canadian Underwriter or Selling Firm is duly registered as a dealer under the Canadian Securities Laws of such province or territory in a category that permits the trade. For the purposes of this Section 9, the Underwriters shall be entitled to assume that the Shares are qualified for distribution in each of the provinces and territories of Canada. For the avoidance of doubt, ▇▇▇▇▇ Fargo Securities, LLC is not acting as an underwriter of the Shares in any province or territory of Canada and no action on the part of ▇▇▇▇▇ Fargo Securities, LLC in its capacity as an underwriter of the offering of Shares in the United States will create any impression or support any conclusion that the firm is acting as a Canadian Underwriter of the Shares in any province or territory of Canada.

(c) The obligations of the Underwriters under this Agreement are several and not joint and several, and no Underwriter will be liable for an act, omission, default or conduct by any other Underwriter or any Selling Firm appointed by any other Underwriter.

(d) The Underwriters that are designated as “Canadian Underwriters” on Schedule I hereto (the “Canadian Underwriters”) shall use their commercially reasonable efforts to complete, and to cause each Selling Firm to complete, the distribution of the Shares as promptly as possible after the Closing Date, and shall, and shall cause each Selling Firm to, after the Closing Date, give prompt written notice to the Company when, in the opinion of the Canadian Underwriters, they have completed distribution of the Shares in the provinces and territories of Canada, including notice of the total proceeds realized or number of Shares sold in each of the provinces and territories of Canada and any other jurisdiction.

10. Indemnity and Contribution.

(a) The Company and PEG Parties jointly and severally agree to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act and each Underwriter’s directors, officers and employees (the “Underwriter Indemnified Parties”), from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by:

(i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any Time of Sale Prospectus, Canadian Final Prospectus, any issuer free writing prospectus (taken together with the Time of Sale Prospectus), any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act (taken together with the Time of Sale Prospectus), or the Prospectus or any amendment or supplement thereto;

(ii) in the case of the Registration Statement or any amendment thereof, any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; or

(iii) in the case of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the Canadian Final Prospectus, any issuer free writing prospectus (taken together with the Time of Sale Prospectus), any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act (taken together with the Time of Sale Prospectus), or the Prospectus or any amendment or supplement thereto, (A) any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading in light of the circumstances under which they were made or (B) any “misrepresentation” as defined under Canadian Securities Laws,

(iv) any order or any inquiry, investigation or proceeding announced, instituted or threatened by any court, securities regulatory authority, stock exchange or by any other competent authority naming an Underwriter as a party, based upon any untrue statement, omission or misrepresentation or alleged untrue statement, omission or misrepresentation in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus, Canadian Final Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus or any amendment or supplement thereto;

(v) any breach or default under any representation, warranty, covenant or agreement of the Company or the PEG Parties in this Agreement to or with the Underwriters; or

(vi) the Company or either of the PEG Parties failing to comply with any requirement of any securities laws relating to the offering of the Shares.

except, in each case, insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission relating to Underwriters’ Disclosure, and, solely with respect to the Company, the PEG Parties’ Information;

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the PEG Parties, the directors of the Company and the PEG Parties, as applicable, the officers and employees of the Company and the PEG Parties, as applicable, and each person, if any, who controls the Company or any PEG Party within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) described in the indemnity contained in subsection (a) of this Section 10, as incurred, but only with respect to untrue statements or omissions or alleged untrue statements or omissions made in the Registration Statement or any amendment thereof, any Time of Sale Prospectus, the Canadian Final Prospectus, any issuer free writing prospectus, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus or any amendment or supplement thereto, with reference to information in reliance upon and in conformity with the Underwriters’ Disclosure.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 10(a) or 10(b), such person (the “indemnified party”) shall promptly notify, in writing, the person against whom such indemnity may be sought (the “indemnifying party”) (but the failure to so notify an indemnifying party shall not relieve such indemnifying party from its obligations hereunder to the extent it was not materially prejudiced as a result thereof and in any event shall not otherwise relieve it from any liability that it may have otherwise than on account of this indemnity agreement), and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay fees and disbursements of such counsel, calculated on a solicitor and his own client basis, related to such proceeding (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below). In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriter Indemnified Parties, (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section and (iii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the PEG Parties and all persons, if any, who control any PEG Party within the meaning of either such Section, and that all such fees and expenses

shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Representatives. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. In the case of any such separate firm for the PEG Parties and such control persons of the PEG Parties, such firm shall be designated in writing by the PEG Parties. Notwithstanding the foregoing, if indemnity is sought pursuant to Section 10(h) below, then, in addition to the fees and expenses of such counsel for the indemnified parties, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one counsel (in addition to any local counsel) separate from its own counsel and that of the other indemnified parties for the QIU in its capacity as a “qualified independent underwriter” and all persons, if any, who control the QIU within the meaning of Section 15 of the 1933 Act or Section 20 of 1934 Act in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances if, in the reasonable judgment of the QIU, there may exist a conflict of interest between the QIU and the other indemnified parties. Any such separate counsel for the QIU and such control persons of the QIU shall be designated in writing by the QIU. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this paragraph, such indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request and such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity or contribution could have been sought hereunder by such indemnified party, unless such settlement (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (y) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) To the extent the indemnification provided for in Section 10(a) or 10(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the aggregate amount of such losses, claims, damages or liabilities incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the PEG Parties on the one hand and the Underwriters on the other hand from the offering of the Shares pursuant to this

Agreement or (ii) if the allocation provided by clause (i) above is not available for any reason, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the PEG Parties on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the PEG Parties on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by each of the Company and the PEG Parties and the total underwriting commissions received by the Underwriters, in each case as set forth in the table on the cover of the Time of Sale Prospectus and the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the Company and the PEG Parties on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the PEG Parties, on the one hand, or by the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 10 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint. The Company, the PEG Parties and the Underwriters agree that ▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated will not receive any additional benefits hereunder for serving as the QIU in connection with the offering and sale of the Shares.

(e) The Company, the PEG Parties and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 10 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 10(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 10(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10, no Underwriter shall be required to contribute any amount in excess of the amount by which total underwriting discounts and commissions received by it exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 10 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 10 and the representations, warranties and other statements of the Company, the PEG Parties and the Underwriters contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, any PEG Party or the Company and (iii) acceptance of and payment for any of the Shares. The provisions of this Section 10 shall not affect any agreement among the Company and the PEG Parties with respect to indemnification or contribution.

(g) The Company and the PEG Parties severally acknowledge and agree that the statements regarding delivery of Shares by the Underwriters set forth on the cover page of the Time of Sale Prospectus and the Prospectus, and, under the caption, “Underwriting”: (i) the [fourth paragraph], concerning dealer concessions and sales to discretionary accounts; (ii) the [eleventh] paragraph concerning internet distributions; and (iii) the [fifteenth] and [sixteenth] paragraphs, concerning stabilization transactions; in the Time of Sale Prospectus and the Prospectus constitute the Underwriters’ Disclosure; and the Underwriters severally confirm that the statements are correct.

(h) In addition to and without limitation of the Company’s and the PEG Parties’ obligation to indemnify ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated as an Underwriter, the Company and the PEG Parties hereby jointly and severally agree to indemnify and hold harmless the QIU, its affiliates ((as such term is defined in Rule 501(b) under the Securities Act) and selling agents and each person, if any, who controls the QIU within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, from and against any and all loss, liability, claim, damage and expense whatsoever, as incurred, incurred as a result of the QIU’s participation as a “qualified independent underwriter” within the meaning of Rule 2720 in connection with the offering of the Securities.

11. Termination. In addition to any other remedies which may be available to the Underwriters, the Representatives on behalf of the Underwriters shall be entitled to terminate and cancel, their obligations under this Agreement, by notice given to the Company, if, after the execution and delivery of this Agreement and prior to the Closing Date: (i) any inquiry, investigation or other proceeding is commenced or any order is issued under or pursuant to any statute of the United States, Canada or of any state, province or territory thereof or otherwise (other than an inquiry, investigation, proceeding or order based upon the activities or alleged activities of the Underwriters or the Selling Firms), or there is any change of law, or the interpretation or administration thereof, which in the reasonable opinion of the Representatives operates to prevent or restrict the trading or the distribution of the Shares, (ii) there shall occur or be discovered by the Representatives any material change in the financial condition, assets, liabilities, business, affairs or operations of the Company and its subsidiaries (taken as a whole), which, in the Underwriters’ reasonable opinion, makes it impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated by the Time of Sale Prospectus and the Prospectus, (iii) there has occurred any material change in the state of the financial markets, which, in the Representatives’ reasonable opinion, makes it impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated by the Time of Sale Prospectus; (iv) there shall occur or have

been announced any change or proposed change in the federal income tax laws of Canada or the United States, the regulations thereunder, current administrative decisions or practices or court decisions, any other applicable rules or the interpretation or administration thereof which, in any such case, in the Representatives’ reasonable opinion, could be expected to have a Material Adverse Effect on the market price or value of the Shares, (v) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the Nasdaq Global Select Market or the Toronto Stock Exchange, (vi) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (vii) a material disruption in commercial banking or securities settlement, payment or clearance services in the United States or Canada shall have occurred, (viii) any moratorium on commercial banking activities shall have been declared by Federal, New York State or Canadian authorities or (ix) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets, currency exchange rates or controls or any calamity or crisis that, in the Representatives’ judgment, is material and adverse and which, singly or together with any other event specified in this clause (ix), makes it, in the Representatives’ judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus. If the Underwriters terminate their obligations hereunder pursuant to this Section 12, the Company’s and the PEG Parties’ only obligation to the Underwriters hereunder shall be limited to the Company’s and any PEG Party’s obligations under Section 10 and payment of expenses referred to in Section 8 hereof.

12. Reliance on the Representatives. All steps or other actions which must or may be taken by the Underwriters in connection with this Agreement shall be taken by the Representatives, with the exception of matters contemplated by Sections 3, 10, 11 and 13 on the Underwriters’ behalf, and the execution of this Agreement by the Underwriters shall constitute the authority of the Company and the PEG Parties for accepting notification of any such steps or other actions from the Representatives.

13. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

(a) If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule I bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 13 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, (i) any

Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on such date and (ii) arrangements satisfactory to you and the Company for the purchase of such Firm Shares are not made within 24 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, the Company or the PEG Parties. In any such case either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

(b) If any Underwriter defaults pursuant to this Section, neither the Company nor the PEG Parties shall be obligated to reimburse such defaulting Underwriter for its out-of-pocket expenses.

14. Relationship with TMX Group Limited. Each of CIBC World Markets Inc. and Scotia Capital Inc., or an affiliate thereof, owns or controls an equity interest in TMX Group Limited (the “TMX Group”) and has a nominee director serving on the TMX Group’s board of directors. As such, each such investment dealer may be considered to have an economic interest in the listing of securities on any exchange owned or operated by TMX Group, including the Toronto Stock Exchange, the TSX Venture Exchange and the Alpha Exchange. No person or company is required to obtain products or services from TMX Group or its affiliates as a condition of any such dealer supplying or continuing to supply a product or service.

15. Entire Agreement. This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Company and PEG Parties, on the one hand, and the Underwriters, on the other, with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

16. Submission to Jurisdiction. The Underwriters, the PEG Parties and the Company irrevocably submit to the non-exclusive jurisdiction of any New York State or United States Federal court sitting in The City of New York over any suit, action or proceeding arising out of or relating to this Agreement, the Prospectus, the Registration Statement, or the offering of the Shares. The Underwriters, the PEG Parties and the Company irrevocably waive, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any such suit, action or proceeding brought in such a court and any claim that any such suit, action or proceeding brought in such a court has been brought in an inconvenient forum.

Each of the Company and the PEG Parties severally acknowledge that in connection with the offering of the Shares to be sold by such party: (i) the Underwriters have acted at arm’s length, are not agents of, and have assumed no, and owe no fiduciary duties to, the Company and the PEG Parties, (ii) the Underwriters owe the Company and the PEG Parties only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters may have interests that differ from those of the Company and the PEG Parties. The Company and the PEG Parties waive to the full extent permitted by applicable law any claims they may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

17. Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase United States dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligation of each of the Company and the PEG Parties with respect to any sum due from it to any Underwriter or any person controlling any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by such Underwriter or controlling person of any sum in such other currency, and only to the extent that such Underwriter or controlling person may in accordance with normal banking procedures purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due to such Underwriter or controlling person hereunder, the Company and the PEG Parties agree as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter or controlling person against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter or controlling person hereunder, such Underwriter or controlling person agrees to pay to the Company an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter or controlling person hereunder.

18. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

19. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

20. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

4th Floor, P.O. Box 150

Ladies and Gentlemen:

The undersigned understands that you, as Representatives of the several Underwriters, propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Pattern Energy Group, Inc., a Delaware corporation (the “Company”), Pattern Renewables LP, a Delaware limited partnership, and Pattern Energy Group LP, a Delaware limited partnership, providing for the public offering (the “Public Offering”) by the several Underwriters named in Schedule I to the Underwriting Agreement (the “Underwriters”), of common stock, par value $0.01 per share (the “Common Stock”), of the Company. Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

In consideration of the Underwriters’ agreement to purchase and make the Public Offering of the Shares, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of each of BMO ▇▇▇▇▇▇▇ ▇▇▇▇▇ Inc. and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC on behalf of the Underwriters, the undersigned will not, during the period ending 180 days after the Closing Date, (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, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (including, without limitation, Common Stock or such other securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and Canadian Securities Laws and securities which may be issued upon exercise of a stock option or warrant), or publicly disclose the intention to make any offer, sale pledge or disposition, or (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock or such other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or

otherwise, or (3) make any demand for or exercise any right with respect to the registration of any shares of Common Stock or any security convertible into or exercisable or exchange for Common Stock without the prior written consent of the Representative, in each case other than (A) transfers of shares of Common Stock as a bona fide gift or gifts, (B) transfers of shares of Common Stock by will or the laws of intestacy, (C) transfers of shares of Common Stock to any person related to the undersigned by blood, marriage or adoption, but no more than first cousin or a trust formed for the benefit of such related person, (D) transfers of shares of Common Stock pursuant to domestic relations or court orders (E) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act or similar plans permitted under Canadian provincial securities laws for the transfer of Common Shares, provided that such plan does not provide for the transfer of Common Stock during the 180-day period and no filing under 16(a) of the Exchange Act or under the securities laws and regulations of the provinces of Canada shall be made in connection with the implementation of any such plan, except to the extent required by law, and provided that none of the Company, the undersigned or any of their respective representatives shall announce or publicly disclose the establishment of such a plan during the 180-day period or (F) in the case of corporations or other entities, transfers of shares of Common Stock to affiliates; provided that, in each case, each donee or transferee shall execute and deliver to BMO ▇▇▇▇▇▇▇ ▇▇▇▇▇ Inc. a lock-up letter in the form of this paragraph; and provided, further, that no filing by any party (donor, donee, transferor, or transferee) under the Securities Exchange Act of 1934, as amended, or Canadian Securities Laws, or other public announcement shall be required or shall be made voluntarily in connection with such transfer or distribution (other than a filing on a Form 5 made prior to the expiration of the 180-day period referred to above).

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Letter Agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs, or personal representatives of the undersigned.

The undersigned understands that, if (i) the Underwriting Agreement does not become effective, (ii) if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder or (iii) the Public Offering is not completed by December 31, 2013, the undersigned shall be released from all obligations under this Letter Agreement. The undersigned understands that the Underwriters are entering into the Underwriting Agreement and proceeding with the Public Offering in reliance upon this Letter Agreement.

This Letter Agreement and any claim, controversy, or dispute arising under or related to this Letter Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.
