ATLANTIC POWER CORPORATION
INFORMATION CIRCULAR AND PROXY STATEMENT

Introduction

              This information circular and proxy statement (the "Information Circular and Proxy Statement") is furnished in connection with the solicitation of proxies by or on behalf of the board of directors (the "Directors", the "Board", or the "Board of Directors", and each one individually, a "Director") of Atlantic Power Corporation (the "Corporation" or "Atlantic Power"), for use at the annual and special meeting (the "Meeting") of the holders ("Shareholders") of common shares ("Common Shares") of the Corporation to be held on June 21, 2016 at the Omni King Edward Hotel, Belgravia Room, 37 King Street East, Toronto, Ontario, Canada M5C 1E9 commencing at 10:00 a.m. (Eastern time), and at all postponements or adjournments thereof, for the purposes set forth in the accompanying notice of the Meeting (the "Notice of Meeting"). In this Information Circular and Proxy Statement, references to "Cdn$" and "Canadian dollars" are to the lawful currency of Canada and references to "$", "US$" and "U.S. dollars" are to the lawful currency of the United States. All dollar amounts herein are in U.S. dollars, unless otherwise indicated. The information contained herein is given as at April              , 2016, except where otherwise noted.

              On or about             , 2016, we intend to mail to our stockholders a notice containing instructions on how to access the Proxy Materials (as defined below) and how to vote their Common Shares online. In accordance with the requirements of National Instrument 54-101—Communication with Beneficial Owners of Securities of a Reporting Issuer, for purposes of distributing to non-registered Shareholders who have requested a copy, the Corporation has distributed copies of this Information Circular and Proxy Statement to the intermediaries for onward distribution to such non-registered Shareholders.

              The U.S. Securities and Exchange Commission (the "SEC") has adopted a "Notice and Access" rule that allows companies to deliver a Notice of Internet Availability of Proxy Materials ("Notice of Internet Availability") to Shareholders in lieu of a paper copy of the Information Circular and Proxy Statement and related materials and the Corporation's Annual Report to Shareholders (collectively, the "Proxy Materials"). The Notice of Internet Availability provides instructions as to how Shareholders can access the Proxy Materials online, contains a listing of matters to be considered at the Meeting, and sets forth instructions as to how shares can be voted. Shares must be voted either by telephone, online or by completing and returning a proxy card. Shares cannot be voted by marking, writing on and/or returning the Notice of Internet Availability. Any Notices of Internet Availability that are returned will not be counted as votes. Instructions for requesting a paper copy of the Proxy Materials are set forth on the Notice of Internet Availability.

              The Corporation is relying on the exemptions set forth in Section 9.1.5 of National Instrument 51-102—Continuous Disclosure Obligations and Section 9.1.1 of National Instrument 54-101—Communication with Beneficial Owners of Securities of a Reporting Issuer from the requirement under Canadian securities laws to send paper copies of the Proxy Materials to registered and beneficial shareholders of the Corporation.

Table of Contents

Important Notice Regarding Availability of Proxy Materials

              The Proxy Materials are available at https://materials.proxyvote.com/04878Q. You will need to enter the control number located on the Notice of Internet Availability or proxy card.

              The Corporation is providing some of its Shareholders, including Shareholders who have previously asked to receive paper copies of the proxy materials and some of its Shareholders who are living outside of the United States and Canada, with paper copies of the proxy materials in addition to a Notice of Internet Availability.

              In addition, the Corporation is providing Notice of Internet Availability by e-mail to those Shareholders who have previously elected delivery of the proxy materials electronically. Those Shareholders should have received an e-mail containing a link to the website where those materials are available and a link to the proxy voting website.

Electronic Access to the Proxy Materials

              You can elect to receive future proxy materials by email, which will save the Corporation the cost of producing and mailing documents to you. Shareholders may enroll to receive proxy materials electronically as follows:

              Shareholders of Record:    If you are a registered shareholder, you may request electronic delivery on the Internet at www.proxyvote.com.

              Beneficial Holders:    If your shares are not registered in your name, check the information provided to you by your bank or broker, or contact your bank or broker for information on electronic delivery service.

Voting and Quorum

              A quorum must be present at the Meeting for any business to be conducted. Pursuant to the Corporation's articles of continuance (the "Articles"), two persons, present in person, each being a Shareholder entitled to vote at a meeting of Shareholders or a duly appointed proxy for a Shareholder so entitled constitutes a quorum. Shares represented by "broker non-votes," as described below, will be considered as present for purposes of constituting a quorum.

              Shareholders may vote by attending the Meeting and voting in person. If you choose not to attend the Meeting, you may still authorize your proxy over the internet or by telephone by following the instructions provided in the Notice of Internet Availability or, if you requested to receive printed Proxy Materials, you may also vote by mailing the accompanying form of proxy ("Form of Proxy") pursuant to instructions provided on the proxy card, or by sending voting instructions ("Voting Instructions") to your nominee in accordance with the procedures set forth below under "—Information for Beneficial Holders of Securities". All shares entitled to vote and represented by properly executed proxies received before the polls are closed at the Meeting, and not revoked or superseded, will be voted at the Meeting in accordance with the instructions indicated on those proxies.

              A "broker non-vote" occurs when a nominee holding Common Shares for a beneficial holder has not received Voting Instructions from such beneficial holder but such nominee submits a Form of Proxy in respect of such Common Shares in accordance with New York Stock Exchange ("NYSE") rules. Generally, under current Canadian securities laws and NYSE rules,

Table of Contents

brokers will not have discretionary authority to vote such uninstructed Common Shares with respect to any matter to be voted upon at the Meeting, except that U.S. brokers will have discretionary authority to vote uninstructed Common Shares with respect to the appointment of auditors as described below, in accordance with NYSE rules.

              For purposes of counting votes, (i) abstentions from voting will be counted as votes cast at the Meeting; however, such abstentions will not be counted as votes cast for or against a matter; and (ii) broker non-votes will not be counted as votes cast at the Meeting, except that broker votes with respect to which U.S. brokers have exercised their discretionary authority to vote uninstructed Common Shares in accordance with NYSE rules shall be counted as votes cast at the Meeting.

Proxy Solicitation and Voting

Solicitation of Proxies

              The solicitation of proxies for use at the Meeting is being made by or on behalf of the Board of Directors of the Corporation. The solicitation of proxies for the Meeting will be made primarily by mail, but proxies may also be solicited personally, in writing or by telephone by employees of the Corporation, at nominal cost. The Corporation will bear the cost in respect of the solicitation of proxies for the Meeting and will bear the legal, printing and other costs associated with the preparation of the Information Circular and Proxy Statement. In addition, Kingsdale Shareholder Services ("Kingsdale") has been retained to assist in the solicitation of proxies for the Meeting at a fee of approximately $85,000, plus associated costs and expenses. The Corporation may also reimburse brokers and other persons holding Common Shares in their name or in the name of nominees for their costs incurred in sending proxy material to their principals in order to obtain their proxies. Kingsdale can be contacted by phone toll-free at 1-866-229-8263 (for calls in Canada and the United States) or 1-416-867-2272 (for callers outside North America) or by e-mail at contactus@kingsdaleshareholder.com.

Appointment and Revocation of Proxies

              Together with the Information Circular and Proxy Statement, the Shareholders will also be provided a Form of Proxy. The persons named in such Form of Proxy are Directors. A Shareholder who wishes to appoint some other person to represent him, her or it at the Meeting may do so by inserting such person's name in the blank space provided in the accompanying Form of Proxy or by completing another proper Form of Proxy. Such other person appointed to represent a Shareholder need not be a Shareholder of the Corporation. The time limit for the deposit of proxies may be waived or extended by the Chair of the Meeting at his or her discretion without notice.

              To be valid, a Form of Proxy must be deposited at the offices of Computershare Investor Services Inc. (the "Agent"), 8th Floor, North Tower, 100 University Avenue, Toronto, Ontario, Canada M5J 2Y1 or returned to the Agent by fax at 1-866-249-7775 (North America) or 416-263-9524 (outside North America), or at the offices of the Corporation by written instrument, fax or any other method of transmitting legibly recorded messages, so as not to arrive later than 10:00 a.m. (Eastern Daylight Time) on June 21, 2016. If the Meeting is adjourned, a Form of Proxy must be deposited at the offices of the Agent 48 hours (excluding Saturdays, Sundays and holidays) before the time set for any reconvened meeting at which the Form of Proxy is to be used.

Table of Contents

              The internet and telephone voting procedures are designed to authenticate Shareholders' identities and to confirm that their instructions have been properly recorded.

              If you hold Common Shares through an intermediary (such as a broker, securities dealer, bank, trust company or similar entity), you may vote by following the voting instruction form provided to you by such intermediary (See Information for Beneficial Holders of Securities).

              The document appointing a proxy must be in writing and completed and signed by a registered Shareholder or his or her attorney authorized in writing or, if the registered Shareholder is a corporation, under its corporate seal or by an officer or attorney thereof duly authorized. Instructions provided to the Agent by a registered Shareholder must be in writing and completed and signed by the registered Shareholder or his or her attorney authorized in writing or, if the registered Shareholder is a corporation, under its corporate seal or by an officer or attorney thereof duly authorized. Persons signing as officers, attorneys, executors, administrators, and trustees or similarly otherwise should so indicate and provide satisfactory evidence of such authority.

              A Shareholder that has given a Form of Proxy may revoke the Form of Proxy: (a) by completing and signing a Form of Proxy bearing a later date and depositing it as aforesaid; (b) by depositing an instrument in writing executed by the Shareholder or by his or her attorney authorized in writing: (i) at the registered office of the Corporation at any time up to and including the last business day preceding the day of the applicable Meeting, or any adjournment thereof, at which the proxy is to be used, or (ii) with the Chair of the Meeting prior to the commencement of such Meeting on the day of such Meeting or any adjournment thereof; or (c) in any other manner permitted by law. In order for a Beneficial Holder (as defined below) to revoke Voting Instructions previously given to his or her intermediary (such as a broker, securities dealer, bank, trust company or similar entity) with respect to the voting of the Common Shares, the Beneficial Holder must carefully follow the procedures and instructions received from his or her intermediary.

Voting of Proxies

              The persons named in the accompanying Form of Proxy will vote such proxy in accordance with the instructions contained therein. Unless contrary instructions are specified, if the accompanying Form of Proxy is executed and returned (and not revoked) prior to the

Table of Contents

Meeting, the Common Shares represented by the Form of Proxy will be voted at the Meeting as follows:

              For more information on these issues, please see the section entitled "Matters to be Considered at the Meeting" in this Information Circular and Proxy Statement.

              The persons appointed pursuant to the Form of Proxy are conferred with discretionary authority with respect to amendments to or variations of matters identified in the Form of Proxy and with respect to other matters that may properly come before the Meeting. In the event that amendments or variations to matters identified in the Notice of Meeting are properly brought before the Meeting, it is the intention of the persons designated in the enclosed Form of Proxy to vote in accordance with their best judgment on such matter or business. At the time of printing the Information Circular and Proxy Statement, the Directors know of no such amendments, variations or other matters.

Information for Beneficial Holders of Securities

              Information set forth in this section is very important to persons who hold Common Shares otherwise than in their own names. A non-registered Shareholder of the Corporation (a "Beneficial Holder") who beneficially owns Common Shares, but whose Common Shares are registered in the name of an intermediary (such as a securities broker, financial institution, trustee, custodian or other nominee who holds securities on behalf of the Beneficial Holder or in the name of a clearing agency in which the intermediary is a participant) should note that only a Form of Proxy deposited by Shareholders whose names are on the records of the Corporation as the registered holders of Common Shares as of the Record Date (as defined below) can be recognized and acted upon at the Meeting.

              Common Shares that are listed in an account statement provided to a Beneficial Holder by a broker are likely not registered in the Beneficial Holder's own name on the records of the Corporation and such Common Shares are more likely registered in either the name of CDS Clearing and Depository Services Inc. ("CDS") or its nominee, or the name of The Depositary Trust Company ("DTC") or its nominee.

              Applicable regulatory policy requires brokers and other intermediaries to seek Voting Instructions from Beneficial Holders in advance of shareholders' meetings. Every broker or other intermediary has its own mailing procedures and provides its own return instructions, which

5


Table of Contents

should be carefully followed by Beneficial Holders in order to ensure that their Common Shares are voted at the Meeting. Often, the voting instruction form (the "Voting Instruction Form") supplied to a Beneficial Holder by its broker is identical to the Form of Proxy provided to registered Shareholders. However, its purpose is limited to instructing the registered Shareholder how to vote on behalf of the Beneficial Holder. Most brokers now delegate responsibility for obtaining instructions from clients to Broadridge Financial Solutions, Inc. ("Broadridge"). Broadridge typically prepares a machine-readable Voting Instruction Form, mails those forms to the Beneficial Holders and asks Beneficial Holders to return Voting Instructions to Broadridge. Broadridge then tabulates the results of all Voting Instructions received and provides appropriate instructions representing the voting of the securities to be represented at the Meeting. A Beneficial Holder receiving a Broadridge Voting Instruction Form cannot use that Voting Instruction Form to vote Common Shares directly at the Meeting. Voting Instructions must be returned to Broadridge well in advance of the Meeting in accordance with the instructions set out on the Voting Instruction Form in order to have the Common Shares voted.

              The internet and telephone voting procedures are designed to authenticate Shareholders' identities and to confirm that their instructions have been properly recorded.

              Generally, Canadian securities laws and NYSE rules prohibit brokers from voting on any of the proposals without receiving Voting Instructions from the Beneficial Holders of the Common Shares, except that U.S. brokers will have discretionary authority to vote uninstructed shares with respect to the appointment of auditors, in accordance with NYSE rules. In the absence of Voting Instructions, Common Shares subject to such broker non-votes will not be counted as voted or as represented on those proposals and so will have no effect on the vote other than with respect to the appointment of auditors where a U.S. broker has exercised its discretionary authority to vote uninstructed shares in accordance with NYSE rules. As brokers generally may not vote your Common Shares in the absence of your specific instructions as to how to vote (except in the limited circumstances described above), we encourage you to provide Voting Instructions to your broker regarding the voting of your Common Shares. If you require assistance voting your shares, please contact Kingsdale Shareholder Services at 1-866-229-8263 (for calls in Canada and the United States) or 1-416-867-2272 (for callers outside North America) or by e-mail at contactus@kingsdaleshareholder.com.

              Although Beneficial Holders may not be recognized directly at the Meeting for the purposes of voting Common Shares registered in the name of CDS, DTC or their broker or other intermediary, a Beneficial Holder may attend the Meeting as proxy holder for the registered Shareholder and vote his or her Common Shares in that capacity. Beneficial Holders who wish to attend the Meeting and indirectly vote their own Common Shares as proxy holder for the registered Shareholder should enter their own names in the blank space on the Voting Instruction Form provided to them and return the same to their broker or other intermediary (or

6


Table of Contents

the agent of such broker or other intermediary) in accordance with the instructions provided by such broker, intermediary or agent well in advance of the Meeting.

Voting Securities and Principal Holders Thereof

              The Corporation is authorized to issue an unlimited number of Common Shares. As of the date of this Information Circular and Proxy Statement, there were                            Common Shares outstanding.

              At the Meeting, each Shareholder of record at the close of business on April 25, 2016, the record date established for the Notice of Meeting and for voting at the Meeting (the "Record Date"), will be entitled to one vote for each Common Share held on all matters proposed to come before the Meeting. At the close of business on the Record Date, there were                           Common Shares outstanding and entitled to be voted at the Meeting.

              To the knowledge of the Board of Directors, there are no persons that beneficially own or exercise control or direction over Common Shares carrying approximately 10% or more of the votes attached to the issued and outstanding Common Shares. For more information, please see the section entitled "Security Ownership of Certain Beneficial Owners and Management" in this Information Circular and Proxy Statement.


CORPORATE GOVERNANCE AND COMMITTEES OF THE BOARD

Board of Directors

              The Corporation is pleased to make the following disclosures regarding its corporate governance practices pursuant to National Policy 58-201—Corporate Governance Guidelines, National Instrument 58-101—Disclosure of Corporate Governance Practices, and Item 407 of Regulation S-K and other applicable rules of the U.S. Securities and Exchange Commission (the "SEC") and NYSE rules:

Table of Contents

              Each Director attended at least 75% of the aggregate of (i) the total number of meetings of the Board of Directors (held during the period for which he or she has been a Director) and (ii) the total number of meetings of all committees of the Board of Directors on which the Director served (during the periods that he or she served).

              The Corporation does not have a policy of requiring its Directors to attend the annual general meeting of Shareholders. The Chair of the Board of Directors is expected to attend and chair meetings of the Shareholders. All eight of the Directors then serving attended the annual meeting held on June 23, 2015.

              The Board of Directors meets as necessary, but no fewer than four times each year: three meetings to review quarterly results and one meeting prior to the issuance of the annual audited financial results of the Corporation. In addition, the Board of Directors generally meets annually in December to discuss the annual budget and in February to discuss the annual strategy and director education (and more frequently if required). The committees of the Board of Directors meet as required by their respective charters. Given the business environment and desire to proactively position the business in light of our 2015 activities, the Board of Directors met more frequently in 2015.

Committees of the Board

              The Board of Directors has established four committees:

8


Table of Contents

               Audit Committee.    The Corporation has established an Audit Committee consisting of Messrs. Gerstein, Duncan and McNeil (who will not stand for reelection at the Meeting) and Mses. Ladhani and Ressel, each of whom is an independent Director under the NYSE corporate governance rules. The Chair of the Audit Committee was, for fiscal year ended 2015, and continues to be Holli C. Ladhani. The Board of Directors has determined that Ms. Ladhani, Ms. Ressel and R. Foster Duncan each qualify as an "audit committee financial expert" as the term is defined in the rules of the SEC. The Audit Committee's primary purposes are to, among other things: (i) assist the Board of Directors in its oversight and supervision of the integrity of the accounting and financial reporting practices and procedures, the implementation and adequacy of the internal accounting controls and procedures and the compliance with legal and regulatory requirements in respect of financial disclosure; (ii) assess and monitor the strategic, operating, reporting and compliance risks of the business; and (iii) supervise the qualification, independence and performance of independent accountants of the Corporation.

              The Audit Committee met 5 times during 2015.

               Compensation Committee.    The Corporation has established a Compensation Committee consisting of Messrs. Howell, McNeil (who will not stand for reelection at the Meeting) and Palter and Mses. Ladhani and Ressel, each of whom is an independent Director under the NYSE corporate governance rules and National Policy 58-201 — Corporate Governance Guidelines. In 2014, Kenneth M. Hartwick acted as the Chair of the Compensation Committee until he was appointed Interim President and Chief Executive Officer of the Corporation after the close of business on September 15, 2014, at which time Mr. John A. McNeil became the acting Chair of the committee. Effective February 23, 2015, Teresa M. Ressel became and continues to be the Chair of the Compensation Committee. The Compensation Committee's primary purposes include: (i) discharging the responsibilities of the Board of Directors relating to compensation of the Chief Executive Officer and other officers; (ii) evaluating the Corporation's compensation plans, policies and programs, taking into account factors it deems appropriate from time to time, including those that are of strategic significance to the Corporation, the degree of risk to the Corporation and its business those plans and policies may imply, and the results of non-binding Shareholder votes with respect to such matters; and (iii) reviewing and discussing with the Corporation's officers the Statement of Executive Compensation, including the Compensation Discussion and Analysis ("CD&A"), to be included in the Corporation's annual information circular and proxy statement and determining whether to recommend to the Board of Directors that the CD&A be included in the information circular and proxy statement. The Compensation Committee may form and delegate its authority to subcommittees consisting of one or more members of the Committee when appropriate. The Compensation Committee did not delegate any of its authority in 2015.

              The Compensation Committee periodically utilizes the services of Pearl Meyer & Partners ("Pearl Meyer"), an independent compensation consultant, to assist it in reviewing its compensation program. The Compensation Committee reviewed and considered the information and advice provided by Pearl Meyer, among other factors, in making its executive compensation recommendations.

              In 2015, Pearl Meyer advised the Compensation Committee in regards to the short-term and long-term incentive awards and compensation market data for the Corporation's named executive officers. Pearl Meyer was directly engaged by the Compensation Committee and management had no role in engaging their consultation. Pearl Meyer did not provide any services to the Corporation other than those provided to the Compensation Committee.

Table of Contents

              The Compensation Committee met 8 times during 2015, notably in connection with the onboarding of our CEO, James J. Moore, Jr. and establishing his executive team throughout the year.

               Nominating and Corporate Governance Committee.    The Corporation has established a Nominating and Corporate Governance Committee consisting of Messrs. Gerstein, Duncan and Howell and Ms. Ressel, each of whom is an independent Director under the NYSE corporate governance rules and National Policy 58-201 — Corporate Governance Guidelines. During the period beginning upon his resignation from service as Interim President and Chief Executive Officer of the Corporation and ending upon his resignation from the Board on March 11, 2016, Mr. Hartwick served as a member of the Nominating and Corporate Governance Committee and was an independent Director under the NYSE corporate governance rules and National Policy 58-201 — Corporate Governance Guidelines. The Chair of the Nominating and Corporate Governance Committee was, for fiscal year ended 2015, and continues to be Irving R. Gerstein. The Nominating and Corporate Governance Committee's primary purposes are to, among other things: (i) screen and identify individuals who are qualified to become members of the Board of Directors; (ii) recommend to the Board, director nominees to be presented for Shareholder approval at the annual meetings of the Shareholders of the Corporation; (iii) recommend to the Board of Directors nominees to fill vacancies on the Board of Directors or as otherwise required outside of the annual meetings of Shareholders of the Corporation; (iv) select, or recommend to the Board of Directors, the Directors to comprise the committees of the Board of Directors; (v) implement a process for examining the size of the Board of Directors and to undertake, where appropriate, a program to establish a Board size which facilitates effective decision-making; (vi) establish procedures for the nomination of Directors and executive officers of the Corporation generally; (vii) establish and administer an annual assessment process relating to the performance of the Board of Directors as a whole, the committees of the Board of Directors and individual Directors; (viii) review with the Board of Directors from time to time the appropriate skills and characteristics required of Directors in the context of the current make-up of the Board of Directors, including issues of diversity, age, skills relating to the Corporation's businesses and professional background; (ix) recommend to the Board of Directors procedures for the conduct of Board meetings and the proper discharge of the Board of Directors' mandate as set out in the mandate of the Board of Directors; (x) monitor the relationship between the officers and the Board of Directors with a view to ensuring that the Board of Directors is able to function independently of officers; (xi) develop the Corporation's approach to governance, including the development of a set of governance principles and guidelines that are specifically applicable to the Corporation; (xii) perform a leadership role in shaping the Corporation's corporate governance practices and provide oversight with respect to its corporate governance conduct; and (xiii) perform such other functions as the Board of Directors may from time to time request.

              In identifying, evaluating, and recommending suitable Director candidates, the Nominating and Corporate Governance Committee may take into account a number of factors, such as the appropriate skills and characteristics required of Directors in the context of the current make-up of the Board of Directors, including issues of diversity, skills relating to the Corporation's businesses and professional background and existing commitments to outside boards. Pursuant to its charter, the Nominating and Corporate Governance Committee, in considering the extent to which the membership of a candidate on the Board of Directors would promote diversity among the Directors, may take into account various factors and perspectives, including differences of viewpoint, professional experience, education, skill and other individual qualities and attributes as well as race, gender and national origin. It is the Corporation's practice to retain an outside recruiting firm to identify a wide range of candidates for review and consideration and to assist in the evaluation process. The Nominating and Corporate

10


Table of Contents

Governance Committee has not formally adopted any specific, minimum qualifications that must be met by each candidate for the Board of Directors, nor are there specific qualities or skills that are necessary for one or more of the members of the Board of Directors to possess. The Nominating and Corporate Governance Committee believes that candidates and nominees must reflect a Board of Directors that is comprised of Directors who have competencies, skills and personal qualities required of Board members in light of relevant factors, including: (1) the objective of adding value to the Corporation in light of the opportunities and risks facing the Corporation and the Corporation's proposed strategies; (2) the need to ensure that a majority of the Board of Directors is comprised of individuals who meet the independence requirements of the applicable securities legislation and stock exchanges or other guidelines, including the Corporation's categorical standards for Director independence; and (3) the policies of the Board of Directors with respect to board member tenure, retirement and succession and Board member commitments.

              It is the policy of the Nominating and Corporate Governance Committee to review and consider any director nominees who have been recommended by Shareholders in the same manner as described above. All Shareholder recommendations for director nominees must be submitted to the Corporate Secretary at Atlantic Power Corporation, 3 Allied Drive, Suite 220, Dedham, Massachusetts 02026 in accordance with the procedures of the Advance Notice Policy (discussed below).

              The Nominating and Corporate Governance Committee met 4 times during 2015.

               Operations and Commercial Oversight Committee.    The Corporation has established an Operations and Commercial Oversight Committee. For fiscal year 2015, the Operations and Oversight Committee consisted of Messrs. Hartwick, Howell, McNeil (who will not stand for reelection at the Meeting) and Duncan, each of whom is (or was in Mr. Hartwick's case) an independent Director under the NYSE corporate governance rules and National Policy 58-201 — Corporate Governance Guidelines. The Chair of the Operations and Commercial Oversight Committee for fiscal year ended 2015 and through the date of his resignation in March 2016 was Mr. Hartwick. On April 6, 2016, Mr. Howell was appointed the Chair of the Operations and Commercial Oversight Committee. The committee's primary purposes include: (i) assisting the Board of Directors in discharging its responsibilities with respect to oversight of the Corporation's plant fleet operations, investment decisions in these plants, divestiture of plants, acquisition of additional assets and the capital required to support the plant fleet; (ii) examining the commercial aspects of the plants including power purchase agreements, re-contracting activity and the associated commercial relationships with customers, and (iii) assessing and monitoring the operating risks of the business.

              The Operations and Commercial Oversight Committee met 2 times during 2015.

Board Leadership Structure

              The Charter of the Board of Directors requires the Chair of the Board of Directors to be an independent director, as it was determined it would be beneficial to have an independent Chair whose sole responsibility is leading the Board of Directors, leaving the Chief Executive Officer's main focus on the Corporation's business goals and promoting both short-term and long-term growth. Currently, Mr. Gerstein serves as the Chair of the Board of Directors. The Chair is expected to attend and chair meetings of the Board of Directors and Shareholders. The Chair ensures that the Board of Directors carries out its responsibilities effectively and the Board of Directors understands the boundaries between Board of Directors and management responsibilities. The Chair is also responsible for providing direction with respect to the dates and frequency of Board of Directors meetings and related committee meetings. The Chair liaises with the Chief Executive Officer to prepare Board of Directors meeting agendas.

              Directors who qualify as "non-management" within the meaning of the NYSE rules meet on a regular basis in executive sessions without management participation and, at least once per year, an executive session is held with only independent directors present. The executive sessions are chaired by the Chair of the Board of Directors. In addition, the Audit Committee, Compensation Committee, Nominating and Corporate Governance Committee and Operations and Commercial Oversight Committee, all of which are comprised entirely of independent Directors, also perform oversight functions independent of management.

Board Mandate

              The mandate of the Board of Directors is included as Schedule "B" to this Information Circular and Proxy Statement.

Position Descriptions

              Position descriptions for the Chair of the Board of Directors, the Chair of the Audit Committee, the Chair of the Compensation Committee, the Chair of the Nominating and Corporate Governance Committee, the Chair of the Operations and Commercial Oversight Committee and the Chief Executive Officer of the Corporations have been developed by the Corporation as previously disclosed by the Corporation in its 2014 Information Circular and Proxy Statement.

Orientation and Continuing Education

              The Corporation, working with the Directors, will provide orientation opportunities for new Directors to familiarize them with the role of the Board of Directors, its committees, and its Directors, as well as the Corporation and its business. All new Directors will participate in an orientation program soon after the date on which a new Director first joins the Board of Directors. To date, the majority of directors have visited power projects of the Corporation to obtain an understanding of the operations of the Corporation. In addition to operational orientation, management has scheduled periodic presentations for the Board of Directors to ensure they are aware of major business trends and industry practices as and when required.

Ethical Business Conduct

              The Board of Directors has adopted a written code of business conduct and ethics for the Corporation (the "Corporate Code"), which sets out basic principles to guide all Directors, officers and employees of the Corporation and its subsidiaries, and a written code of business conduct and ethics for the Chief Executive Officer and senior financial officers (the "Officer Code" and, together with the Corporate Code, the "Codes"), which sets out basic principles to guide the Chief Executive Officer and the senior financial officers of the Corporation.

              The issues the Corporate Code addresses include, among other things, the following:

              The issues the Officer Code addresses include, among other things, the following:

              To ensure the Directors exercise independent judgement in considering transactions, agreements or decisions in respect of which a Director or officer has declared a material personal interest (in accordance with relevant corporate law requirements), the Board of Directors follows a practice whereby any such individual must not cast a vote on any such matter.

              The senior officers of the Corporation and the Chair of the Audit Committee are responsible for monitoring compliance with the Corporate Code and the Officer Code, respectively, and are required to report to the Board of Directors or the Audit Committee, respectively, on any issues that have arisen under the applicable Code. Any waivers from the requirements in the Codes that are to be granted for the benefit of the Directors, managers or executive officers of the Corporation are to be granted by the Directors only (or a committee of

13


Table of Contents

the Board of Directors to whom that authority has been delegated) and will be promptly disclosed as required by law or stock exchange regulation.

              At least annually, the Board of Directors reviews the adequacy of the Codes.

              The Codes are available on the Corporation's website at www.atlanticpower.com under "ABOUT US — Codes of Conduct" and under the Corporation's profile on the System of Electronic Document Analysis and Retrieval ("SEDAR") at www.sedar.com. Information contained on the Corporation's website or that can be accessed through the Corporation's website is not incorporated into and does not constitute a part of this Information Circular and Proxy Statement. The Corporation has included its website address only as an inactive textual reference and does not intend it to be an active link to its website.

              The Corporation's Whistleblower Policy is administered by the Chair of the Audit Committee. Any person may confidentially report complaints or concerns directly to the Chair of the Audit Committee. Confidentiality of complaints or concerns received by the Chair of the Audit Committee will be maintained to the fullest extent possible, consistent with the need to conduct an appropriate review.

Risk Oversight

              The Audit Committee receives and discusses a risk assessment update each quarter which is reviewed and discussed with management prior to the Audit Committee's recommendation to the Board of Directors to approve quarterly and annual financial disclosures. In addition, the Board of Directors receives periodic Operations Reports about each of the Corporation's projects with full opportunity for Directors to ask questions of management about any potential issues identified.

Assessments

              The charter of the Nominating and Corporate Governance Committee includes establishing and administering an annual assessment process relating to the performance of the Board of Directors as a whole, the committees of the Board of Directors and individual Directors, including the size and composition of the Board of Directors.

Director Term Limits

              Each Director holds office until the next annual meeting of the Shareholders or until his or her successor is elected or appointed. The Board of Directors does not impose term limits on its Directors as it does not believe that arbitrary limits on the number of consecutive terms a Director may serve or on the Directors' ages are appropriate in light of the substantial benefits resulting from a sustained focus on the Corporation's business, strategy and industry over a significant period of time, without assuring increased independence. Accordingly, the Board's assessment of independence is of prime importance to ensure that retention of experience does not result in a failure to retain a sufficient number of independent Directors. The Board of Directors relies on thorough Director assessment procedures for evaluating its members (including their independence), and uses rigorous identification and selection processes for new directors, having regard to a variety of factors. In addition, to be identified as independent a Director must be determined to be independent both in character and in judgement and free from any relationships or circumstances which are likely to affect, or could appear to affect, their judgement. Particular scrutiny is applied in assessing the continued independence of Directors

14


Table of Contents

having served over nine years, with attention to ensuring that their tenure has not in any way eroded their independence and that their allegiance remains clearly aligned with shareholders.

              Through these processes, the Board of Directors believes that it is well-positioned to address any problems or deficiencies that may arise as well as evaluate independence of Directors in an appropriate manner without having to adopt mandated term limits.

Representation of Women on the Board and in Executive Officer Positions

              While the Corporation supports the principle of diversity in its leadership, of which gender is an important aspect, the Corporation has not formally adopted a policy or targets regarding the representation of women on the Board of Directors or in its senior management, as the Corporation does not believe that quotas or strict rules necessarily result in the identification or selection of the best candidates. Rather, the identification and selection process is made based on a variety of factors, such as differences of viewpoint, professional experience, education, skill and other individual qualities and attributes, including race, gender and national origin, as well as the requirements of the Board of Directors and senior management at the time. In addition, in identifying, evaluating and recommending suitable Director candidates, the Nominating and Corporate Governance Committee will take into account the criteria described under the section entitled "Corporate Governance Disclosure—Nominating and Corporate Governance Committee" of this Information Circular and Proxy Statement. Accordingly, in searches for new Directors and executive officers, the Corporation will consider the level of female representation and diversity on the Board of Directors and in its senior management and this will be one of several factors used in its search process. The Corporation will, however, continue to evaluate the appropriateness of adopting a formal policy and/or targets in the future.

              Following the Meeting and assuming all of the nominees for Director are elected as contemplated in this Information Circular and Proxy Statement, two of the seven Directors on the Board of Directors will be women (representing nearly 30% of the Directors). As of the date hereof, none of the Corporation's three executive officers are women.

Communications with the Board of Directors

              Shareholders and other interested parties who wish to communicate with the Chair of the Board of Directors or independent Directors as a group, may do so by writing to them at Name(s) of Director(s)/Independent Directors of Atlantic Power Corporation, c/o Corporate Secretary, Atlantic Power Corporation, 3 Allied Drive, Suite 220, Dedham, Massachusetts 02026.

MATTERS TO BE CONSIDERED AT THE MEETING

MATTER 1: ELECTION OF DIRECTORS

              The number of Directors to be elected at the Meeting is seven. The persons named in the accompanying Form of Proxy will vote such proxy in accordance with the instructions contained therein. Unless contrary instructions are specified, if the accompanying Form of Proxy is executed and returned (and not revoked) prior to the Meeting, the Common Shares represented by the Form of Proxy will be voted for the election, as Directors, of the proposed nominees whose names are set out below.

Majority Voting Policy

              The Board of Directors has adopted a majority voting policy. Under this policy, a Director in an uncontested election who receives more votes withheld than cast in favour of his or her election will be required promptly to tender his or her resignation to the Chair of the Board of Directors following the applicable meeting of the Corporation's Shareholders. The resignation will be effective when accepted by the Board of Directors. The Nominating and Corporate Governance Committee of the Board of Directors will consider whether or not to accept the offer of resignation and will recommend to the Board of Directors whether or not to accept the resignation. A Director who tenders his or her resignation pursuant to the majority voting policy is not permitted to participate in any meeting of the Board of Directors and/or Nominating and Corporate Governance Committee at which his or her resignation is to be considered. With the exception of special circumstances that would warrant the continued service of the applicable Director on the Board of Directors, the Nominating and Corporate Governance Committee expects that resignations will be recommended for acceptance and accepted by the Board of Directors. Within 90 days following the applicable meeting of the Shareholders, the Board of Directors will make a decision on the Nominating and Corporate Governance Committee's recommendation. The Board of Directors will promptly announce its decision (including, if applicable, the reasons for not accepting any resignation) via press release in accordance with applicable securities laws, rules and regulations.

Advance Notice Policy

              The Corporation has adopted an advance notice policy (the "Advance Notice Policy"), which requires advance notice to the Corporation in circumstances where nominations of persons for election to the Board of Directors are made by Shareholders other than pursuant to: (i) a proposal made in accordance with the British Columbia Business Corporations Act ("BCBCA"); or (ii) a requisition of the Shareholders made in accordance with the BCBCA. Among other things, the Advance Notice Policy fixes a deadline by which Shareholders must submit director nominations to the corporate secretary of the Corporation prior to any annual or special meeting of Shareholders and sets forth the specific information that a Shareholder must include in such notice for an effective nomination to occur. Pursuant to the Advance Notice Policy, no person will be eligible for election as a director of the Corporation unless nominated in accordance with the provisions of the Advance Notice Policy.

              Pursuant to the Advance Notice Policy, in the case of an annual meeting of Shareholders, notice to the Corporation must be made not less than 30 nor more than 65 days prior to the date of the annual meeting; provided, however, that in the event that the annual meeting is to be held on a date that is less than 50 days after the date on which the first public announcement of the date of the annual meeting was made by the Corporation, notice may be made not later than the close of business on the 10th day following such public announcement. In the case of a special meeting of Shareholders (which is not also an annual meeting), notice to the Corporation must be made not later than the close of business on the 15th day following the day on which the first public announcement of the date of the special meeting was made.

On May 21, 2015, the Corporation entered into an agreement (the "Mangrove Agreement") with Mangrove Partners, a Cayman Islands exempted company, on behalf of itself and its affiliated and managed funds, persons, and entities, both current and future (collectively, the "Mangrove Group"). Pursuant to the Mangrove Agreement, the Board of Directors increased the size of the Board to nine directors, appointed Gilbert S. Palter to the Board to serve until the Meeting and agreed not to increase the size of the Board in excess of nine members and not to decrease the size of the Board if such decrease would require Mr. Palter's resignation without the Mangrove Group's consent until a certain date.

Corporate Strategy and Performance—Achievements and Business Highlights

              We remain focused on growing the intrinsic value per share of the Corporation and increasing our discretionary cash flow in order to allocate our capital in ways that provide for a good return to the Corporation. We continue to prioritize repurchases of our debt and equity, which are currently trading at compelling price-to-value levels. We continue to identify and make additional attractive investments in our fleet, some of which are linked to possible contract extensions. We value the environment and the health and well-being of our operations personnel and continue to make investments to maintain our fleet in a strong operational status at all times.

              The Company's key accomplishments in 2015 were as follows:

Table of Contents

              Project Adjusted EBITDA, Adjusted Cash Flows from Operating Activities and Adjusted Free Cash Flow are not measures recognized under GAAP and do not have standardized meanings prescribed by GAAP, and are therefore unlikely to be comparable to similar measures presented by other companies. Project Adjusted EBITDA and Adjusted Cash Flows from Operating Activities were used as performance metrics for our short-term incentive plan and are discussed below. A reconciliation from cash flows from operating activities (a GAAP measure) to Adjusted Free Cash Flow is included in Schedule C.

              The following describes the Corporation's compensation policies and practices as they relate to our named executive officers included in this CD&A.

Executive Compensation Objectives

              The primary objective of our executive compensation program is to provide a competitive, performance-based plan that enables the Corporation to attract, retain and motivate key individuals. Compensation plays an important role in achieving short-term and long-term business objectives that ultimately drive value creation and business success in alignment with long-term shareholder goals. The objectives of the Corporation's compensation program are to:

Table of Contents

              The compensation program of the Corporation has been established in order to compete with remuneration practices of companies similar to the Corporation and those which represent potential competition for the Corporation's executive officers and other employees. In this respect, the Corporation identifies remuneration practices and remuneration levels of companies that are likely to compete for its talent. In designing the compensation program, the Board of Directors works to provide competitive market compensation opportunities for each of our named executive officers. The Board of Directors reviews each element of compensation for market competitiveness and may weigh a particular element more heavily based on the named executive officer's role.

              Our executive compensation program is administered by our independent Compensation Committee.

2015 Say-on-Pay Vote

              At the Corporation's Annual Meeting of Shareholders held on June 23, 2015, 91.03% of the votes cast on the Say-on-Pay proposal regarding the executive compensation of the Corporation's named executive officers identified in the Corporation's 2015 Information Circular and Proxy Statement voted in favour of the proposal. The Compensation Committee believes this strong affirmative vote confirms Shareholders' support of the Corporation's approach to executive compensation. The Compensation Committee will continue to consider the outcome of the Corporation's annual "say-on-pay" votes when making future compensation decisions for named executive officers.

Key Compensation Decisions in 2015

              Overall 2015 was a successful year for the Corporation as demonstrated by the achievements listed in the executive summary to this report. Despite our strong financial and strategic performance in 2015, the valuation of our stock price lagged the market. As a result the value of our outstanding equity awards for all of our employees is below grant levels. The Board also reviews stock price performance when making compensation decisions. As a result the performance of our stock price, which is also heavily impacted by external market factors outside of management's control, has a substantial impact on our executive compensation program. The following chart reflects the target and actual incentive plan awards for 2015.

Elements of Executive Compensation

              Our compensation program for our named executive officers includes a base salary, cash bonus under the short-term incentive plan ("STIP") and eligibility for equity compensation awards under the long-term incentive plan ("LTIP"), as reflected in their respective employment agreements, all of which have been approved by the Compensation Committee and the Board of Directors. Mr. Hartwick's compensation during his tenure as Interim President and Chief Executive Officer was comprised of base salary only.

              The base salaries for the named executive officers for 2015 were based on a review by the Compensation Committee with a goal of ensuring that the base salaries are appropriate and competitive. This review was based on the level of responsibility, the experience level, competitive salaries for similar positions in the market, and an individual's personal contribution to the Corporation's operating and financial performance.

              The named executive officers and other employees of the Corporation are eligible to participate in the short-term incentive plan ("STIP") as determined by the Board of Directors. The STIP is intended to compensate executives for achieving the Corporation's short-term business strategy based on the achievement of goals set by the board compensation committee.

              The Corporation used three performance metrics in its STIP plan with weightings and descriptions provided as follows:

25%—Project Adjusted EBITDA    Project Adjusted EBITDA is used to assess the operating performance of the projects without the effects of depreciation and amortization expense, income tax expense or recoveries, interest expense, unrealized gains or losses on derivative financial instruments, non-cash write downs of intangibles and property, plant and equipment, gains or losses on foreign exchange, earnings or loss from discontinued operations and other infrequent items unrelated to normal ongoing operations. Project Adjusted EBITDA includes the Corporation's proportional share of equity method projects. Project Adjusted EBITDA does not include corporate G&A expense. The criteria used to determine this component consists of Project Adjusted EBITDA relative to the $209 million approved budget.

25%—Adjusted Cash Flows from Operating Activities    Adjusted Cash Flows from Operating Activities is used to evaluate cash flows from operating activities without the effects of changes in working capital balances, acquisition expenses, litigation expenses, severance and restructuring charges, debt prepayment and redemption costs and cash provided by or used in discontinued operations. The intent is to reflect normal operations and remove items that are not reflective of the long-term operations of the business. The criteria used to determine this component consists of cash flow from operating activities relative to the $104 million approved budget.

50%—Discretionary    The discretionary component of the award is based on the evaluation of the Corporation's overall performance, shareholder value, stakeholder value, optimization initiatives, environmental, health & safety (EH&S) and other qualitative measures including leadership, commitment and overall effectiveness.

              Each performance metric is measured against pre-determined performance targets and awarded based on the following sliding scale.

              The Compensation Committee developed and approved the Corporation's STIP to determine the cash awards payable to James J. Moore, Jr., Terrence Ronan, and Joseph E. Cofelice. Payouts under the STIP to Messrs. Moore, Ronan and Cofelice are included in the column identified as "Non-equity incentive plan compensation" in the Summary Compensation Table on page 40; The Compensation Committee set target ranges for each named executive officer's cash award based on base salary. The same performance measures were chosen for all executives.

STIP Awards in respect of the 2015 Performance Year

              In January 2016, the Compensation Committee determined that Messrs. Moore, Ronan and Cofelice were eligible for annual incentive awards under the pre-established performance criteria noted above. The Compensation Committee made these awards based primarily on the achievements of the Corporation relating to the three performance measures.

Measurement Category
  Actual Result
Project Adjusted EBITDA (25%)   The criteria used to determine this component will consist of Project Adjusted EBITDA relative to the $209 million approved budget. Actual Project Adjusted EBITDA for the year was $209 million, resulting in a 100% payout of this component.

Adjusted Cash Flow from Operating Activities (25%)

 

The criteria used to determine this component will consist of cash flow from operating activities relative to the $104 million approved budget. Actual Adjusted Cash flow from Operating Activities for the year was $105 million, resulting in a 100% payout of this component.

Discretionary (50%)

 

The discretionary component of the award is based on the evaluation of the Corporation's overall performance, shareholder value, stakeholder value, optimization initiatives, EH&S and other qualitative measures.

              The Compensation Committee assessed Messrs. Moore, Ronan and Cofelice's performance in terms of their individual groups as well as the relationship of their achievements to the direction of the Corporation as a whole. It is the view of the Compensation Committee that 2015 was a successful year for Atlantic Power as it achieved many strategic objectives set earlier in the year as described above. The stock price did not reflect the many accomplishments achieved such as deleveraging, cost reductions, investment in the fleet and credit upgrades. The STIP measures and targets must be evaluated in context of the overall assessment of the Corporation's performance. The STIP awards approved by the Compensation Committee were a result of this approach and ultimately the awards to Messrs. Moore, Ronan and Cofelice reflect the fact that overall results were above expectations.

              For the STIP award paid in 2016 based on the 2015 performance year, Mr. Moore's award was determined to be $740,000 based on the Compensation Committee's review of the components of the STIP, including the review of certain subjective factors. In particular, Mr. Moore contributed to the Corporation's achievement of its goals described above in the areas of strategy and leadership, specifically focusing on reducing G&A, the significant reduction of debt and increasing our intrinsic value per share.

              Mr. Ronan's STIP award was determined to be $400,000 based on the Compensation Committee's review of the components of the STIP, including the review of certain subjective factors. In particular, Mr. Ronan contributed to the Corporation's achievement of its goals described above in the areas of financial and risk management, specifically focusing on reshaping the balance sheet.

              Mr. Cofelice's STIP award was determined to be $106,400, prorated based on his hire date, based on the Compensation Committee's review of the components of the STIP, including the review of certain subjective factors. In particular, Mr. Cofelice contributed to the Corporation's achievement of its goals described above in the areas of commercial management and our recontracting efforts.

              The table below shows the STIP awards paid to the Corporation's named executive officers in 2016 based on the 2015 performance year as a percentage of each officer's 2015 base salary. For comparison purposes, the table also includes the awards paid to the Corporation's named executive officers in 2015 based on the 2014 performance year as a percentage of each officer's 2014 base salary.

              The named executive officers and other employees of the Corporation are eligible to participate in the long-term incentive plan ("LTIP") as determined by the Board of Directors. The purpose of the LTIP is to align the interests of employees with those of the Shareholders by

Table of Contents

providing an opportunity to increase their share ownership over time and to assist in attracting, retaining and motivating key employees of the Corporation by making a significant portion of their incentive compensation directly dependent upon the achievement of strategic, financial and operational objectives critical to growing the Corporation and increasing its long-term value.

              2015 awards made under the LTIP for the Corporation's executive officers were based on the following performance metrics and weightings:

              Up to 50% of the target award will be earned in respect of each performance measure subject to the Compensation Committee's exercise of discretion to take into account such other factors as it may deem appropriate. Awards will be granted annually based on the performance during the prior fiscal year and vest according to specific terms outlined in executive contract to one third over each of the three years following the year the award is granted. Although the LTIP uses relative TSR as one of the two performance measures, the Compensation Committee also looks at absolute TSR in the context of the entire award to ensure alignment.

              TSR refers to the rate of return that a Shareholder would earn on an investment in Common Shares assuming the investment was held for the entire year and that monthly dividends, if any, were reinvested. For 2015, the Compensation Committee included the following companies in the peer group (the "TSR Peer Group") for the purpose of determining the Corporation's relative TSR performance:

              For each performance period, the Board of Directors establishes LTIP award amounts that each named executive officer is entitled to receive under the LTIP depending upon the Corporation's performance against specified criteria. If certain levels of target performance are achieved, the named executive officer will be eligible to receive a number of notional shares to be calculated by dividing an incentive amount by the market price per Common Share. The market price per Common Share is defined in the LTIP as the weighted average closing price of a Common Share on the TSX for the five trading days immediately preceding the applicable day and then converted to U.S. dollars based on the exchange rate for that day. Notional shares are meant to track the investment performance of Common Shares, including market prices and distributions. Any notional shares granted to a participant in respect of a

34


Table of Contents

performance period will be credited to a notional share account for each participant on the determination date for such performance period. Each notional share is entitled to receive distributions equal to the distributions on a Common Share, if any, to be credited in the form of additional notional shares immediately following such distribution on the Common Shares.

2016 LTIP Awards in respect of the 2015 Performance Year

              For 2015, the possible quantum of awards under the LTIP ranged from zero to a cap of $575,000 for the Chief Executive Officer and $400,000 for each of the Executive Vice President—Chief Financial Officer and Executive Vice President—Commercial Development. For 2015, the midpoint target was relative TSR—60th to 75th percentile of the peer group. If this target range were achieved in 2015, and the Compensation Committee determined to award the full discretionary portion of the award, the recommended award for our Chief Executive Officer would be $287,500 and for each of our Executive Vice President—Chief Financial Officer and our Executive Vice President—Commercial Development would be $200,000, prorated based on hire date.

              The following table indicates the thresholds established for each performance measure under the LTIP for 2015 and corresponding percentages of the target award at each level of performance, as well as the actual level of achievement for each performance measure. Up to 50% of the award would have been earned in respect of each performance measure, subject to the Compensation Committee's exercise of discretion to take into account such other factors as it may deem appropriate.

Target and Actual Performance Measures under LTIP for Fiscal Year Ended December 31, 2015

(Each Performance Measure comprises 50% of potential LTIP award)

GRAPHIC

              In 2015, the Corporation's TSR of –24.5% (45th percentile) was in the bottom half of the Corporation's TSR Peer Group.

              On December 18, 2015, the Compensation Committee determined to make the following awards for the 2015 performance year. The Compensation Committee made these awards based primarily on the achievements of the Corporation relating to the measures above and also by exercising its discretion under the LTIP. The Compensation Committee assessed Messrs. Moore, Ronan and Cofelice's performance in terms of their specific functions as well as the relationship of their achievements to the direction of the Corporation as a whole.

Table of Contents

              Mr. Moore received a grant of $345,000 or 192,737 notional shares, which represents approximately 60% of the award available under the LTIP. Under the terms of Mr. Moore's employment agreement, this grant shall vest upon the three-year anniversary of the date of grant, as follows, provided Mr. Moore remains employed by the Corporation upon the vesting date, and the portion of each award that does not so vest shall be immediately and automatically forfeited for no consideration: (i) at 150% of the original grant amount, if the Corporation's Relative TSR (as defined in the LTIP) is at the 75th percentile or higher, (ii) at 100% of the original grant amount, if the Corporation's Relative TSR is at the 50th percentile or higher, but below the 75th percentile, (iii) at 50% of the original grant amount, if the Corporation's Relative TSR is at the 25th percentile or higher, but below the 50th percentile or (iv) at 0% of the original grant amount, if the Corporation's Relative TSR is below the 25th percentile, or, regardless of the Corporation's Relative TSR, if, as of the vesting date, the Market Price per Common Share (as defined in the LTIP) is below the Market Price Per Common Share as of the date of grant.

              Mr. Ronan received a grant of $240,000 or 134,078 notional shares, which also represents approximately 60% of the maximum award available under the LTIP.

              Mr. Cofelice received a grant of $80,000 (prorated based on hire date) or 44,693 notional shares, which also represents approximately 60% of the maximum award available under the LTIP.

              Mr. Hartwick was not eligible to receive an LTIP grant under the terms of his employment agreement entered into in September 2014.

              It is the view of the Compensation Committee that 2015 was a successful year for Atlantic Power as evidenced by the following accomplishments:

              Our Committee believes the LTIP measures and targets must be evaluated in context of the overall assessment of the Corporation's performance. The LTIP awards approved by the

36


Table of Contents

Compensation Committee were a result of this approach and ultimately the awards to Messrs. Moore, Ronan and Cofelice reflect the fact that management had very good execution in 2016, but relative TSR was below the minimum threshold set above. The notional shares awarded will each vest as to one third over each of the three years following the year in which the award was granted, subject to continued employment of the officer.

              The Compensation Committee also used the following criteria to determine the nature and amount of the award while considering TSR in context of the entire award to ensure alignment:

              Pursuant to SEC rules and Canadian securities laws, these awards will be reported in the Summary Compensation Table in the Information Circular and Proxy Statement for the Corporation's 2017 Annual Meeting of Shareholders.

Compensation Allocation

              The following provides the overall mix of actual compensation for 2015 for each of our named executive officers. Overall, approximately 60-65% of our total compensation package for our named executive officers is considered incentive (variable) compensation that changes year to year based on actual company and individual performance achievement.

Table of Contents

one-time grant of notional shares, each corresponding to one Common Share of the Corporation, with an initial grant value of $1,350,000 subject to certain vesting requirements outlined in the agreement.

              Effective April 15, 2013, the Corporation entered into an employment agreement with Mr. Ronan. The agreement provides Mr. Ronan with benefits including the following: (i) an initial annual base salary, which is subject to annual review and if increased may not be subsequently decreased without the executive officer's consent during the term of the agreement; (ii) eligibility to participate in the STIP adopted by the Board of Directors from time to time, provided that the STIP may not be altered to the material detriment of the executive officer without his consent; (iii) eligibility to participate in the LTIP as it may be amended by the Board of Directors from time to time, provided that the LTIP may not be altered to the material detriment of the executive officer without his consent; and (iv) benefits under the Corporation's welfare plans. This employment agreement has an initial three year term ending March 31, 2016. Beginning in 2014, on January 1 of each year this three-year employment agreement extends automatically for an additional one-year term unless notice is given by the Corporation or the officer that the agreement will not be renewed.

              Effective on September 16, 2015, the Corporation entered into an employment agreement with Mr. Cofelice. The employment agreement provides Mr. Cofelice with (i) an initial annual base salary, which is subject to annual review and pro-rated for 2015; (ii) eligibility to participate in the STIP adopted by the Board of Directors from time to time, pro-rated for 2015; (iii) eligibility to participate in the LTIP as it may be amended by the Board of Directors from time to time, pro-rated for 2015; (iv) benefits under the Corporation's welfare plans; (v) a one-time grant of notional shares with a grant date value of $200,000, subject to the terms and conditions of the LTIP.

Clawback

              Messrs. Moore, Ronan and Cofelice agree to be subject to a Financial Restatement and Clawback policy under which, in the event the Corporation's financial results are restated or are found to be inaccurate in a manner that materially affects the calculation of compensation for the executive officers, the independent directors of the Corporation may, subject to certain conditions, direct that the Corporation recover all or a portion of bonus or incentive compensation paid to the executive officer or gains realized by the executive officer with respect to equity-based awards or other incentive payments or cancel all or a portion of the stock-based awards granted to the executive officer that is related to a restatement of, or inaccuracy in, the Corporation's financial results due to intentional fraud or misconduct by the executive officer, and may take other disciplinary action in addition to remedies imposed by third parties, such as law enforcement agencies, regulators or other authorities, and any right of recoupment under Section 304 of the Sarbanes-Oxley Act of 2002, or otherwise required by law or stock exchange requirements. In the event of an inaccuracy that does not give rise to a restatement, any amount recovered, cancelled or recouped under the policy will not exceed the amount by which the compensation based on the inaccurate financial results exceeded the compensation calculated under the accurate financial results.

              Each executive officer's employment agreement also contains certain provisions regarding termination of employment and change in control benefits. For a description of these provisions and post-employment restrictive covenants, see the section of this Information Circular and Proxy Statement titled "Potential Payments Upon Termination or Change in Control." None of our employment agreements provides for any excise tax or gross-ups for the benefit of our executive officers.

Retirement Benefits

              The Corporation does not sponsor a defined benefit retirement plan or any supplemental or enhanced retirement benefits for its named executive officers. The Corporation makes annual matching contributions to each named executive officer's 401(k) plan account based upon a predetermined formula that applies to all its employees. The matching contributions supplement employee's personal savings toward future retirement.

Perquisites

              The Corporation does not provide any material perquisites to its named executive officers.

Share Ownership Policy

              The Board of Directors has adopted a share ownership policy for the Corporation's executive officers in order to further align the interests of the Corporation's executive officers and directors with the long-term interests of the Shareholders. The Policy provides that within five years of appointment the CEO must own shares at 3 times his annual base salary and 2 times for the other executives.

              For purposes of the Policy, share ownership includes any shares owned, directly or indirectly, by an executive or his or her immediate family members or held by such person or his or her immediate family members as part of a tax or estate plan, and unvested notional shares or other equity securities issued under an equity or equity-based compensation plan of the Corporation. In the event of a decline in the price of the Corporation's Common Shares by 25% or more in any year such that the value of an executive officer's Common Shares falls below the requirements of the Policy, the executive officer will have a period of one year to acquire additional Common Shares to comply with the Policy. If the share ownership Policy for any executive officer is not met within the required time frame, the executive officer will be required to have 100% of his or her notional shares or equity-based compensation vest into Common Shares (in both cases, less Common Shares withheld or sold to pay taxes) until the requirements of the Policy are met.

              For purposes of determining compliance with the Policy, the value of a share means an assumed per share value based on the average of the closing price of a Common Share on the New York Stock Exchange on the last trading day of each of the previous four fiscal quarters. The Policy went into effect on April 1, 2013, and the five-year grace period under the Policy, as described above, is still in effect for each of the Corporation's executive officers.

Compensation Committee Report

              The Compensation Committee of the Board of Directors of the Corporation has reviewed and discussed the Compensation Discussion and Analysis ("CD&A") required by Item 402(b) of Regulation S-K with management and, based on such review and discussions, the Compensation Committee recommended to the Board of Directors that the CD&A be included in this Information Circular and Proxy Statement.

Potential Payments Upon Termination or Change In Control

              We believe that the consideration of a change in control transaction will create uncertainty regarding the continued employment of our executive officers. This uncertainty results from the fact that many change in control transactions result in significant organizational changes, particularly at the executive officer level. In order to encourage our executive officers to focus on seeking the best return for our Shareholders and to remain employed with the Corporation during an important time when their prospects for continued employment following a change in control transaction are often uncertain, we have agreed in the employment agreements to provide for severance benefits in the event the executive officer's employment is terminated under certain circumstances, including in connection with a change in control of the Corporation. In exchange for such severance protection, each executive officer agreed to certain non-competition and non-solicitation limitations following certain termination events.

              The Corporation's employment agreement with James J. Moore, Jr. provides that if he is terminated by the Corporation (other than in the one-year period following a change of control)for any reason other than cause, or if Mr. Moore terminates his employment for good reason, then the following are paid or provided under the employment agreement: (i) his base salary through the termination date, to the extent not yet paid; (ii) a lump sum termination payment equal to two times his then current base salary (without giving effect to any material salary reduction), plus a pro-rata amount, based on the number of days elapsed during the fiscal year in which the Date of Termination occurs, of the target bonus; (iii) immediate vesting of LTIP which had not yet vested (including any unvested portion of his transitional grant) with respect to (a) 0% of the target award if before the six-month anniversary of the effective date of the employment agreement, (b) 50% of the target award if between the six-month anniversary of the effective date of the employment agreement and the twelve-month anniversary of that date or (c) 100% of the target award if after the twelve-month anniversary of that date and (iv) continuation of medical and life insurance benefits for a period of eighteen months following termination. In the event Mr. Moore is terminated by the Corporation for any reason other than cause or if Mr. Moore terminates his employment for good reason within one year of a change in control, then the following are paid or provided under the employment agreement: (i) his base salary through the termination date, to the extent not yet paid; (ii) a lump sum termination payment equal to either (a) US$2,000,000, if such termination is within twelve months of the effective date of the employment agreement or (b) if such termination is later, two times his then current base salary (without giving effect to any material salary reduction), plus a pro-rata amount, based on the number of days elapsed during the fiscal year in which the Date of Termination occurs, of the target bonus; (iii) immediate vesting of LTIP which had not yet vested (including any unvested portion of his transitional grant) with respect to (a) 0% of the target award if before the twelve-month anniversary of the effective date of the employment agreement or (b) 100% of the target award if after the twelve-month anniversary of that date and (iv) continuation of medical and life insurance benefits for a period of eighteen months following termination. After the first anniversary of the effective date of the employment agreement, Mr. Moore will receive the same benefits with respect to a termination without cause or a termination for good reason, regardless of whether such termination is in connection with a change in control. In order to receive these termination benefits (other than unpaid base salary through termination date), the executive officer must execute a general waiver and release of claims against the Corporation and its affiliates. Under Mr. Moore's employment agreement, a change in control is defined as the occurrence of any of the following events: (i) the sale, lease or transfer to any person or group, in one or a series of related transactions, of the assets of the Corporation or Atlantic Power Services, LLC which assets generated more than

43

50% of Atlantic Power Services, LLC's cash flow in a 12-month period ended on the last day of the most recent fiscal quarter to any person or group; (ii) the adoption of a plan related to the liquidation or dissolution of the Corporation or Atlantic Power Services, LLC; (iii) the acquisition by any person or group of a direct or indirect interest in more than 50% of (A) the common shares of the Corporation or the common membership interests of Atlantic Power Services, LLC or (B) the voting power of the Corporation or Atlantic Power Services, LLC, in the case of either (A) or (B), by way of purchase, merger, or consolidation or otherwise (other than a creation of a holding company that does not involve a change in the beneficial ownership of the Corporation or Atlantic Power Services, LLC as a result of such transaction); or (iv) the merger or consolidation of the Corporation or Atlantic Power Services, LLC with or into another person or the merger of another person into the Corporation or Atlantic Power Services, LLC with the effect that immediately after such transaction the shareholders of the Corporation or the holders of common membership interests of Atlantic Power Services, LLC immediately prior to such transaction hold, directly or indirectly, less than 50% of the voting control over the person surviving such merger or consolidation, in each case other than the creation of a holding company that does not involve a change in the beneficial ownership of the Corporation or Atlantic Power Services, LLC as a result as such transaction. In the event that Mr. Moore's employment is terminated as a result of his death, disability or retirement, he will be entitled to receive his accrued salary through the date of termination, and each equity-based award held by Mr. Moore shall vest in accordance with the applicable plan or grant or agreement.

              The Corporation's employment agreement with Terrence Ronan provides that if he is terminated by the Corporation either following a determination by the Board of Directors that the executive officer's performance is unsatisfactory with respect to annually approved goals and objectives (with 90 days prior written notice to the executive officer, and not during any period that is 90 days preceding or one year following a change in control) or for any reason other than cause, or if he resigns within 90 days preceding or one year after a change in control because certain further triggering events have occurred including material reduction in salary or benefits (including annual cash bonus or LTIP), relocation, change in position (including status, offices, titles and reporting relationships), authority, duties or responsibilities, or the Corporation's breach of the employment agreement, then the following are paid or provided under the employment agreement: (i) his base salary through the termination date, to the extent not yet paid; (ii) a lump sum termination payment equal to two times the average, during the last two years, of the sum of the respective executive officer's: (a) base salary, (b) annual cash bonus, and (c) the most recent matching contribution to his 401(k) plan (the sum of (a), (b) and (c) being the executive officer's "Total Annual Compensation"); (iii) immediate vesting of all previous awards under the LTIP which had not yet vested; (iv) continuation of all employee benefits for a period of one year following termination; and (v) costs of outplacement services customary for senior executives at the respective executive officer's level for a period of 12 months following termination with the cost capped at $25,000. Under Mr. Ronan's employment agreement, a change in control is defined as the occurrence of any of the following events: (i) the sale, lease or transfer to any person or group, in one or a series of related transactions, of the assets of the Corporation or Atlantic Power Holdings, Inc. which assets generated more than 50% of Atlantic Power Holdings, Inc.'s cash flow in a 12-month period ended on the last day of the most recent fiscal quarter to any person or group; (ii) the adoption of a plan related to the liquidation or dissolution of the Corporation or Atlantic Power Holdings, Inc.; (iii) the acquisition by any person or group of a direct or indirect interest in more than 50% of (A) the common shares of the Corporation or the common membership interests of Atlantic Power Holdings, Inc. or (B) the voting power of the Corporation or Atlantic Power Holdings, Inc., in the case of either (A) or (B), by way of purchase, merger, or consolidation or otherwise (other than a creation of a holding company that does not involve a change in the

beneficial ownership of Atlantic Power Holdings, Inc. as a result of such transaction); (iv) the merger or consolidation of the Corporation or Atlantic Power Holdings, Inc. with or into another person or the merger of another person into the Corporation or Atlantic Power Holdings, Inc. with the effect that immediately after such transaction the shareholders of the Corporation or the holders of common membership interests of Atlantic Power Holdings, Inc. immediately prior to such transaction hold, directly or indirectly, less than 50% of the voting control over the person surviving such merger or consolidation, in each case other than the creation of a holding company that does not involve a change in the beneficial ownership of the Corporation or Atlantic Power Holdings, Inc. as a result as such transaction; or (v) the Corporation or Atlantic Power Holdings, Inc. or any of their shareholders or members enters into any agreement providing for any of the foregoing, or the date which is 90 days prior to a definitive announcement by the Corporation or Atlantic Power Holdings, Inc. of any of the foregoing, whichever is earlier, and the transaction contemplated thereby is ultimately consummated. In order to receive these termination benefits (other than unpaid base salary through the termination date), the executive officer must execute a general waiver and release of claims against the Corporation and its affiliates.

              The Corporation's employment agreement with Joseph E. Cofelice provides that if he is terminated by the Corporation for any reason other than cause, or if Mr. Cofelice terminates his employment for good reason, then the following are paid or provided under the employment agreement: (i) his base salary through the termination date, to the extent not yet paid; (ii) a lump sum termination payment equal to his then current base salary (without giving effect to any material salary reduction), plus a pro-rata amount, based on the number of days elapsed during the fiscal year in which the Date of Termination occurs, of the target bonus; (iii) immediate vesting of LTIP which had not yet vested and (iv) continuation of medical insurance benefits for a period of one year following termination. In order to receive these termination benefits (other than unpaid base salary through termination date), the executive officer must execute a general waiver and release of claims against the Corporation and its affiliates. In the event that Mr. Cofelice's employment is terminated as a result of his death, disability or retirement, he will be entitled to receive his accrued salary through the date of termination, and each equity-based award held by Mr. Cofelice shall vest in accordance with the applicable plan or grant or agreement.

              The employment agreements also contain non-competition and non-solicitation limitations on each of the executive officers following certain termination events.

              The following table provides, for Mr. Moore, Mr. Ronan and Mr. Cofelice, an estimate of the payments payable by us, assuming certain termination scenarios. The amounts shown assume that such termination was effective, and to the extent applicable, a change in control occurred, as of December 31, 2015 and thus only include amounts earned through such time and are estimates of the amounts that would be paid out to the executives upon their

the Corporation agreed to reimburse Mr. Hall for legal fees he expended in connection with his severance agreement in an amount up to $5,000.

Compensation Risk Assessment

              The Corporation has reviewed the Corporation's compensation policies and practices for all employees and concluded that any risks arising from the Corporation's policies and programs are not reasonably likely to have a material adverse effect on the Corporation. The Corporation believes that the mix and design of the elements of executive compensation do not encourage management to assume excessive risks. The Corporation reviewed the elements of executive compensation to determine whether any portion of executive compensation encouraged excessive risk taking and concluded:

              To complement the existing risk-reducing features of the Corporation's compensation policies and practices, the Corporation determined to adopt a share ownership policy that promotes long-term ownership by the named executive officers and to implement a recoupment policy in the executive officers' employment agreements.

Information Concerning the Board of Directors

Compensation of Directors

Director Fees

              Effective January 1, 2015, the Director compensation structure changed such that each independent Director is entitled to receive an annual retainer of $120,000, of which 50% will be paid in cash and 50% will be granted in DSUs with the goal to align Director compensation with the long-term interests of shareholders via mandatory holdings. Directors may elect to receive greater than 50% of their compensation in DSUs. The Chair of the Board of Directors (including for his responsibilities as Chair of the Nominating and Corporate Governance Committee), the Chair of the Audit Committee, the Chair of the Operations and Commercial Oversight Committee and the Chair of the Compensation Committee receive an additional $45,000, $15,000, $10,000 and $10,000 per year, respectively. Committee chair fees are also paid 50% in cash and 50% granted in DSUs. Directors are reimbursed for out-of-pocket expenses for attending meetings but do not receive a per-meeting fee. Directors also participate in insurance and indemnification arrangements. Directors who are also executive officers of the Corporation are not entitled to any compensation for their services as a Director.

Share Ownership Policy

              On April 1, 2013, the Board of Directors adopted the Director and Executive Officer Share Ownership Policy in order to further align the interests of the Directors with the long-term interests of the Shareholders. The Policy provides that all independent Directors are required to acquire (and thereafter maintain ownership of) a number of Common Shares (which will include notional shares under the DSU Plan described below) with a fair market value equal to a minimum of three times their annual base cash retainer within a period of three years of their respective appointment.

              For purposes of the Policy, share ownership includes any shares owned, directly or indirectly, by a Director or his or her immediate family members or held by such person or his or her immediate family members as part of a tax or estate plan, and DSUs issued under the DSU Plan. In the event of a decline in the price of the Corporation's Common Shares by 25% or more in any year such that the value of a Director's Common Shares falls below the requirements of the Policy set out above, the Director will have a period of one year to acquire additional Common Shares to comply with the Policy. If the Policy is not met within the required time frame, the Director will be required to elect at the earliest possible time in accordance with the provisions of the deferred share unit plan (the "DSU Plan") for Directors (described below) to have 100% of the fees paid to him or her by the Corporation for his or her services as a Director contributed to the DSU Plan until the Policy is met.

              For purposes of determining compliance with the Policy, the value of a share means an assumed per share value based on the average of the closing price of a Common Share on the New York Stock Exchange on the last trading day of each of the previous four fiscal quarters. As of the market close December 31, 2015, for the previous 4 quarters then ended, the per share value was $2.43. As of December 31, 2015, all independent Directors were in compliance with, or in the case of Ms. Ressel, subject to the three-year grace period of the Policy as calculated with three times the annual base cash retainer of $60,000.

Deferred Share Unit Plan

              On April 24, 2007, the Board of Directors established a DSU Plan for Directors. Under the DSU Plan, each non-management Director is entitled to elect to have a portion of the fees paid to him or her by the Corporation for his or her services as Directors contributed to the DSU Plan. All fees contributed to the DSU Plan are credited to such Director in the form of DSUs representing the current market price of the Corporation's Common Shares at the time of contribution. For as long as the participant continues to serve on the Board of Directors, dividends, if any are declared, accrue on the DSUs consistent with amounts declared by the Board of Directors on the Corporation's Common Shares and additional DSUs representing the dividends are credited to the Director's account. DSUs credited to the participant's DSU account are redeemed only when a participant ceases to serve on the Board of Directors for any reason. DSUs are redeemed in cash on the first anniversary of the participant's termination as a Director (unless a participant elects another time no later than the end of the calendar year following the year of termination), or, in the case of participants subject to United States income tax, as soon as practicable following the participant's termination. Under the DSU Plan, the Corporation also has the discretion to provide for the redemption or substitution of DSUs upon a reorganization of the Corporation.

              The following table describes Director compensation for non-management Directors for the year ended December 31, 2015.

Compensation Committee Interlocks and Insider Participation

              During 2015, Messrs. Howell and McNeil and Mses. Ressel and Ladhani served as members of the Compensation Committee of the Board of Directors of the Corporation.

              During 2015, none of the executive officers of the Corporation has served as: (i) a member of the compensation committee (or other committee of the board of directors performing equivalent functions or, in the absence of any such committee, the entire board of directors) of another entity, one of whose executive officers served on the Compensation Committee of the Corporation; (ii) a director of another entity, one of whose executive officers served on the Board of Directors of the Corporation; or (iii) a member of the compensation committee (or other committee of the board of directors performing equivalent functions or, in the absence of any such committee, the entire board of directors) of another entity, one of whose executive officers served on the Board of Directors of the Corporation.

MATTER 2: SPECIAL BUSINESS—NON-BINDING ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION

              We have designed our compensation programs to keep management and Shareholders in alignment as to long-term goals as well as to attract, retain and focus our team on delivering value to Shareholders. As more fully discussed in the CD&A beginning on page 25:

Table of Contents

              Project Adjusted EBITDA and Adjusted Free Cash Flow are not measures recognized under generally accepted accounting principles in the United States ("GAAP") and do not have standardized meanings prescribed by GAAP, and are therefore unlikely to be comparable to similar measures presented by other companies. Reconciliations of project income/(loss) (a GAAP measure) to Project Adjusted EBITDA and cash flows from operating activities (a GAAP measure) to Free Cash Flow are included on page 64 of the Corporation's Annual Report on Form 10-K for the year ended December 31, 2015 filed with the SEC on March 7, 2016. A reconciliation from cash flows from operating activities (a GAAP measure) to Adjusted Free Cash Flow is included in Schedule C.

              We urge you to read the CD&A, as well as the Summary Compensation Table and related compensation tables and accompanying narrative, which provide detailed information on our compensation philosophy, policies and practices and the compensation of our named executive officers.

              As required by Section 14A of the Exchange Act, the Corporation is seeking an advisory (non-binding) vote on the compensation paid to the Corporation's named executive officers, as disclosed in this Information Circular and Proxy Statement pursuant to Item 402 of Regulation S-K, including the CD&A, compensation tables and narrative discussion. As previously disclosed by the Corporation, the Board of Directors has determined that it will hold an advisory vote on executive compensation on an annual basis, and the next such advisory vote will occur at the 2017 annual meeting of Shareholders.

              This vote, commonly known as a Say-on-Pay proposal, gives Shareholders the opportunity to express their views on the compensation of the Corporation's named executive officers. This vote is not intended to address any specific item of compensation, but the overall compensation of the named executive officers and the principles, policies and practices described in this Information Circular and Proxy Statement. As this is an advisory vote, the result will not be binding on the Corporation, the Board of Directors or the Compensation Committee. However, the Board of Directors and the Compensation Committee value the opinions of Shareholders and intend to take into account the results of the vote when considering future compensation decisions for the named executive officers.

Vote Required

              Approval of the resolution approving, on a non-binding advisory basis, the compensation of the Corporation's named executive officers requires the affirmative vote of a majority of the votes cast at the Meeting. The persons named in the accompanying Form of Proxy will vote such proxy in accordance with the instructions contained therein. Unless contrary instructions are specified, if the accompanying Form of Proxy is executed and returned (and not revoked) prior to the Meeting, the Common Shares represented by the Form of Proxy will be voted in favour of a resolution to approve, on a non-binding advisory basis, the compensation of the Corporation's named executive officers. The Board of Directors recommends that Shareholders vote in favour of the following resolution:

              RESOLVED, that the Corporation's Shareholders approve, on an advisory basis, the compensation of the named executive officers, as disclosed in the Corporation's Information Circular and Proxy Statement for the 2016 Annual Meeting of Shareholders pursuant to the executive compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the Summary Compensation Table and the other related tables and disclosure.

Table of Contents

               The Board of Directors, upon recommendation of the Compensation Committee, recommends a vote FOR approval, on a non-binding advisory basis, of the compensation paid to our named executive officers, as disclosed in this Information Circular and Proxy Statement.

MATTER 3: APPOINTMENT OF AUDITORS

              The Audit Committee recommends to the Shareholders that KPMG LLP be appointed as the independent auditor of the Corporation, to hold office until the next annual meeting of the Shareholders or until their successor is appointed, and that the Directors be authorized to fix the remuneration of the auditors.

              It is anticipated that a representative of KPMG LLP will attend the Meeting, will have an opportunity to make a statement if he or she desires to do so and will be available to respond to appropriate questions.

Vote Required

              The affirmative vote of a majority of the votes cast at the Meeting is required to appoint KPMG LLP as auditors of the Corporation and to authorize the Board of Directors to fix their remuneration. The persons named in the accompanying Form of Proxy will vote such proxy in accordance with the instructions contained therein. Unless contrary instructions are specified, if the accompanying Form of Proxy is executed and returned (and not revoked) prior to the Meeting, the Common Shares represented by the Form of Proxy will be voted in favour of a resolution to appoint KPMG LLP as auditors of the Corporation and authorize the Corporation's Board of Directors to fix their remuneration. In addition, U.S. brokers will have discretionary authority to vote uninstructed shares with respect to the appointment of auditors.

External Auditor Fees

              Aggregate fees for professional services rendered by KPMG LLP for the years ended December 31, 2015 and 2014 were as follows:

Fees   2015   2014  

Audit Fees

  $ 1,150,000   $ 1,480,000  

Audit-Related Fees

         

Tax Fees

    507,000     622,000  

All Other Fees

         

Total Fees

  $ 1,657,000   $ 2,102,000  

              The Audit Committee pre-approves all auditing services and the terms thereof (which may include providing comfort letters in connection with securities underwritings) and non-audit services (other than non-audit services prohibited under Section 10A(g) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or the applicable rules of the SEC or the Public Company Accounting Oversight Board) to be provided to the Corporation by KPMG LLP; however, the pre-approval requirement is waived with respect to the provision of non-audit services for the Corporation if the "de minimis" provisions of Section 10A(i)(1)(B) of the Exchange Act are satisfied. There were no services provided under the "de minimis" provisions in 2015. The authority to pre-approve non-audit services may be delegated to one or more members of the Audit Committee, who shall present all decisions to pre-approve an activity to the full Audit Committee at its first meeting following such decision.

MATTER 4: Special Business—Reconfirmation of the Rights Plan

Reconfirmation of the Shareholders' Rights Plan

              The Corporation adopted and entered into the Rights Plan with Computershare Investor Services Inc., as Rights Agent, on February 28, 2013. The purposes of the Rights Plan were: (i) to provide the Board of Directors and Shareholders with sufficient time to consider any take-over bid made for the Corporation and to allow enough time for competing bids and alternative proposals to emerge; (ii) to ensure that all Shareholders are treated fairly in any transaction involving a change of control of the Corporation and that all Shareholders have an equal opportunity to participate in the benefits of a take-over bid; and (iii) to encourage potential acquirers to make a Permitted Bid (as defined in the Rights Plan) or, alternatively, to negotiate the terms of any offer for Common Shares with the Board of Directors.

              In order to remain effective, the terms of the Rights Plan require that it be reconfirmed by Shareholders at every third annual Shareholders meeting. The Board of Directors believes that it is in the best interest of Shareholders' that the Rights Plan be reconfirmed for the reasons described below.

              At the Meeting, Shareholders will be asked to consider and, if deemed advisable, pass the Rights Plan Resolution reconfirming the Rights Plan. If the Rights Plan Resolution is approved at the Meeting by the Shareholder votes described below under "Shareholder Approval", the Rights Plan will continue in effect until it is required to be reconfirmed again by Shareholders at the 2019 annual meeting of Shareholders of the Corporation. If the Rights Plan Resolution is not approved, the Rights Plan will terminate as of the date of termination of the Meeting. The full text of the Rights Plan Resolution appears in Schedule "A" of this Information Circular and Proxy Statement.

Take-Over Bid Amendments

              On February 25, 2016, the Canadian securities administrators published certain amendments to the Canadian take-over bid regime (the "TOB Amendments") that will require that all non-exempt take-over bids:

Under the previous regime, non-exempt take-over bids were only required to remain open for 35 days and were not subject to any minimum tender requirement or an extension requirement once the bidder had taken up deposited securities. The TOB Amendments will become effective for all Canadian issuers on May 9, 2016.

              While the TOB Amendments provide many of the protections provided by the Rights Plan, the TOB Amendments do not address the risk of a "creeping take-over bid" where an acquirer may acquire a controlling position in an issuer in reliance on exemptions from the take-over bid requirements and without having to make a take-over bid to all shareholders. As a result, the Board has determined that it is in the best interests of the Corporation to maintain the Rights Plan to attempt to prevent "creeping take-over bids" and the acquisition of control by a third party without paying an appropriate control premium.

              The Board of Directors believes that the Rights Plan is consistent with the TOB Amendments, current Canadian corporate best practices and addresses institutional investor guidelines. The Rights Plan is not intended to prevent a take-over of the Corporation. Reconfirmation of the Right Plan is not being sought in response to, or in anticipation of, any pending or threatened take-over bid and the Board of Directors is not aware of any third party considering or preparing any proposal to acquire control of the Corporation.

Background

              The Rights Plan, which is in a typical form for Canadian publicly-listed issuers, was reviewed by the Corporation's Board of Directors, which reviewed and considered the Rights Plan with the Corporation's legal advisors. The Rights Plan is designed to encourage the fair and equal treatment of Shareholders in connection with any take-over bid for the Corporation. While applicable securities legislation addresses many concerns about unequal treatment of Shareholders, there remains a possibility that control or effective control may be acquired pursuant to private agreements in which a small number of Shareholders dispose of Common Shares at a premium to the market price and other Shareholders have no opportunity to participate, or that a control position could be accumulated over time without payment of fair value for control or fair sharing of any control premium among all Shareholders. The Rights Plan enables the Corporation to preserve its ability to obtain the best value for all Shareholders. Under the Rights Plan, one share purchase right was issued and attached to each outstanding Common Share of the Corporation as of March 11, 2013. The rights become exercisable only if a bidder acquires or announces an intention to acquire a total of 20% or more of the Corporation's outstanding Common Shares, other than pursuant to a Permitted Bid as defined in the Rights Plan and subject to the ability of the Board of Directors to defer the time at which the rights become exercisable. Following the acquisition of 20% of the outstanding Common Shares by the bidder, each right held by a person other than the bidder would entitle the holder to purchase Common Shares at a substantial discount to their then prevailing market price. The issuance of the Common Shares upon exercise of the rights is subject to receipt of regulatory approval.

Summary

              On February 28, 2013, pursuant to the Rights Plan, one Common Share purchase right (individually, a "Right" and, collectively, the "Rights") was issued for each outstanding Common Share to Shareholders of record at the close of business on March 11, 2013 (the "Record Time"). One Right has been and will be issued in respect of each Common Share issued thereafter, subject to the limitations set forth in the Rights Plan. The Rights Plan utilizes the mechanism of the "Permitted Bid" (as described below) to protect Shareholders by requiring all potential bidders to comply with the conditions specified in the Permitted Bid provisions or else such bidders are subject to the dilutive features of the Rights Plan.

              Under the Rights Plan, the Rights are evidenced by the certificates evidencing Common Shares until the close of business on the tenth trading day after the earliest of: (i) the first date of

55


Table of Contents

public announcement by the Corporation or an Acquiring Person (as defined below) of facts indicating that a person has become an Acquiring Person; (ii) the date of commencement of, or first public announcement of the intent of any person (other than the Corporation or any subsidiary of the Corporation) to commence, a take-over bid, other than a Permitted Bid or a Competing Permitted Bid (each as defined below); or (iii) the date upon which a Permitted Bid or Competing Permitted Bid ceases to qualify as such, or such later date as may be determined by the Board of Directors, in good faith (the "Separation Time"). Prior to the Separation Time, the Rights will not be exercisable. Following the Separation Time, each Right will entitle the registered holder to purchase from the Corporation one Common Share at a price of $100 per Common Share, subject to adjustment pursuant to the terms of the Rights Plan (the "Exercise Price").

              Under the Rights Plan, if a transaction or event occurs that results in a person becoming an Acquiring Person (a "Flip-in Event") then the Rights beneficially owned by an Acquiring Person, its associates, affiliates and any person acting jointly or in concert with the foregoing (or any direct or indirect transferee or successor of such Rights) will become null and void and the Rights (other than those beneficially owned by the Acquiring Person, its associates, affiliates and any person acting jointly or in concert with the foregoing or any transferee of such Rights) entitle the holder to purchase, effective at the close of business on the tenth business day after the first date of public announcement by the Corporation or an Acquiring Person of facts indicating that a person has become an Acquiring Person, for the Exercise Price, that number of Common Shares having an aggregate market price equal to twice the Exercise Price, subject to adjustment in certain circumstances.

              An "Acquiring Person" is a person that beneficially owns 20% or more of the Corporation's outstanding voting shares, other than the Corporation or any subsidiary of the Corporation, an underwriter acquiring voting shares from the Corporation in connection with a distribution of securities, a Grandfathered Person (as defined below) or any person that would become an Acquiring Person as a result of certain exempt transactions. These exempt transactions include, among others, (i) acquisitions pursuant to a Permitted Bid or a Competing Permitted Bid, (ii) certain other specified exempt acquisitions, and (iii) transactions to which the application of the Rights Plan has been waived by the Board of Directors. A "Grandfathered Person" means each person that beneficially owns, as of the effective date of the Rights Plan, 20% or more of the outstanding voting shares, except that (a) each such person will be considered a Grandfathered Person only if and so long as the voting shares that are beneficially owned by such person do not exceed the number of voting shares which are beneficially owned by such person as of the effective date of the Rights Plan, plus any additional voting shares representing not more than 1% of the Common Shares outstanding as of the effective date of the Rights Plan, and (b) a person will cease to be a Grandfathered Person immediately at such time as such person ceases to be the beneficial owner of 20% or more of the voting shares then outstanding.

              The Rights Plan is not triggered by a Permitted Bid or a Competing Permitted Bid.

              A "Permitted Bid" is a take-over bid where the bid is made by way of a take-over bid circular to all registered holders of the Corporation's voting shares, other than the offeror, and the bid is subject to irrevocable and unqualified conditions (and only so long as all the conditions are met) that (i) no voting shares shall be taken up or paid for prior to the close of business on a date which is not less than 60 days after the date of the take-over bid and then only if more than 50% of the outstanding voting shares held by Independent Shareholders (as defined below) have been deposited or tendered pursuant to the take-over bid and not withdrawn, (ii) voting shares may be deposited pursuant to the take-over bid (unless the

56


Table of Contents

take-over bid is withdrawn) at any time prior to the date on which voting shares are first taken up and paid for under the take-over bid and may be withdrawn until taken up and paid for, and (iii) if on the date on which voting shares may be taken up and paid for, more than 50% of the voting shares held by Independent Shareholders have been deposited or tendered pursuant to the take-over bid and not withdrawn, that fact will be publicly announced by the offeror and the take-over bid will be extended for at least 10 business days following such announcement.

              "Independent Shareholders" means holders of Common Shares, but shall not include (i) any Acquiring Person or any offeror, or any affiliate or associate of such Acquiring Person or such offeror, or any person acting jointly or in concert with such Acquiring Person or such offeror, or (ii) any person holding Common Shares under any employee benefit plan, stock purchase plan, deferred profit sharing plan or any similar plan or trust for the benefit of employees of the Corporation or a subsidiary of the Corporation, unless the beneficiaries of any such plan or trust direct the manner in which the Common Shares are to be voted or direct whether the Common Shares are to be deposited or tendered to a take-over bid.

              A "Competing Permitted Bid" is a take-over bid made after a Permitted Bid or another Competing Permitted Bid has been made and prior to the expiry of that Permitted Bid or Competing Permitted Bid and that satisfies all the criteria of a Permitted Bid except that since it is made after a Permitted Bid has been made, the minimum deposit period and the time period for the take-up of and payment for voting shares tendered under a Competing Permitted Bid is not 60 days, but is instead the later of (i) 35 days after the date the Competing Permitted Bid is made, and (ii) the earliest date for take-up and payment of voting shares under any other Permitted Bid or Competing Permitted Bid then in existence.

              Neither a Permitted Bid nor a Competing Permitted Bid is required to be approved by the Board of Directors and such bids may be made directly to Shareholders. Acquisitions of the Corporation's voting shares made pursuant to a Permitted Bid or a Competing Permitted Bid do not give rise to a Flip-in Event.

Certificates and Transferability

              The Rights Plan provides that, until the Separation Time, the Rights may be transferred with and only with the Common Shares and certificates for Common Shares will evidence one Right for each Common Share represented by the certificate. Certificates for Common Shares issued after the Record Time shall bear a legend stating that each certificate also represents one Right. Promptly after the Separation Time, separate certificates evidencing the Rights ("Right Certificates") will be mailed to holders of record of Common Shares as of the Separation Time (other than an Acquiring Person and other excluded persons pursuant to the terms of the Rights Plan). Such separate Right Certificates alone will evidence the Rights. Until a Right is exercised, the holder thereof, as such, will have no rights as a shareholder of the Corporation, including no right to vote or to receive dividends.

Redemption, Waiver and Amendment

              The Board of Directors may, at any time prior to the occurrence of a Flip-In Event, with the consent of the majority of Independent Shareholders if prior to the Separation Time or the majority of the holders of Rights (other than an Acquired Person or other holder excluded by the terms of the Rights Plan) if after the Separation Time, redeem the Rights in whole, but not in part, at a price of $0.0001 per Right, subject to adjustment (the "Redemption Price"). Immediately upon any redemption of the Rights, the right to exercise the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price.

57


Table of Contents

              The Board of Directors may, at any time prior to the occurrence of a Flip-in Event that would occur by reason of an acquisition of the Corporation's Common Shares otherwise than pursuant to a take-over bid made by means of a take-over bid circular to all holders of record of Common Shares, with the prior consent of the majority of Independent Shareholders, waive the application of the Rights Plan to such Flip-in Event. In such event, the Board of Directors will extend the Separation Time to a date at least 10 business days following the meeting of Shareholders called to approve such waiver.

              The Board of Directors may also waive the application of the Rights Plan to a Flip-in Event, if the Board of Directors has determined that the Acquiring Person became an Acquiring Person by inadvertence and without any intention to become, or knowledge that it would become, an Acquiring Person. Any such waiver must be on the condition that such Acquiring Person: (a) has, within 30 days after the Board of Directors' determination (or such earlier or later date as the Board of Directors decides), reduced its beneficial ownership of the voting shares such that it is no longer an Acquiring Person; or (b) enters into a contractual arrangement with the Corporation, on terms acceptable to the Board of Directors, to reduce its beneficial ownership of voting shares within 30 days of the entry into such contractual arrangement; and in the event of such waiver, for the purposes of the Rights Plan, the Flip-in Event shall be deemed never to have occurred.

              In the event that, prior to the occurrence of a Flip-in Event, a person acquires Common Shares pursuant to a Permitted Bid, a Competing Permitted Bid or pursuant to a take-over bid for which the Board of Directors has waived the application of the Rights Plan, then the Corporation shall, immediately upon the consummation of such acquisition and without further formality, redeem the Rights for the Redemption Price.

              The Board of Directors may, at any time prior to the occurrence of a Flip-in Event that would occur by reason of a take-over bid for all of the voting shares made by means of a take-over bid circular sent to all holders of record of voting shares, waive the application of the Rights Plan to such Flip-in Event by prior written notice delivered to the Rights Agent, provided however, that if the Board of Directors waives the application of the Rights Plan to such Flip-in Event, the Board of Directors shall be deemed to have waived the application of the Rights Plan to any other Flip-in Event occurring by reason of any take-over bid for all voting shares which is made by means of a take-over bid circular sent to all holders of record of voting shares prior to the expiry, termination or withdrawal of any take-over bid in respect of which a waiver is, or is deemed to have been granted.

              Prior to the Separation Time, the Corporation may, by resolution of the Board of Directors and with the prior consent of the majority of Independent Shareholders, supplement or amend the Rights Plan and the Rights (whether or not such action would materially adversely affect the interests of the holders of the Rights generally). Following the Separation Time, the Corporation may, by resolution of the Board of Directors and with the prior consent of the majority of the holders of the Rights (other than an Acquiring Person or other holder as excluded by the terms of the Rights Plan), supplement or amend the Rights Plan and the Rights (whether or not such action would materially adversely affect the interests of the holders of the Rights generally).

Term

              If reconfirmed at the Meeting, the Rights Plan must be reconfirmed at every third annual meeting following the Meeting, or the Rights Plan and the Rights will otherwise terminate on the date of the meeting if the Rights Plan is not reconfirmed or presented for reconfirmation.

58


Table of Contents

Notwithstanding the foregoing, the Rights will terminate on the close of business on February 28, 2023.

Effect of Rights Plan

              The Board of Directors believes that the ultimate effect of the Rights Plan is to ensure equal treatment of Shareholders in the context of an acquisition of control. It is not the intention of the Board of Directors to entrench itself or avoid a bid for control that is fair and in the best interest of the Corporation. For example, Shareholders may tender to a bid that meets the Permitted Bid criteria without triggering the Rights Plan, regardless of the acceptability of the bid to the Board of Directors. The Rights Plan does not diminish or detract from the duty of the Board of Directors to act honestly, in good faith and in the best interests of the Corporation, or to consider on that basis any take-over bid that is made, nor does the Rights Plan alter the proxy mechanism to change the Board of Directors, create dilution on the initial issue of the Rights, or change the way in which the Common Shares trade. The Rights Plan was not adopted in response to, or in anticipation of, any known take-over bid or proposal to acquire control of the Corporation.

Shareholder Approval

              In order for the resolution reconfirming the Rights Plan to be effective, at least a majority of the votes cast by Shareholders present in person or represented by proxy at the Meeting must be voted in favour of the Rights Plan Resolution. If the Rights Plan Resolution is passed at the Meeting, the Rights Plan will continue in effect. If the Rights Plan Resolution is not passed, the Rights Plan will become void and of no further force and effect and the Corporation will no longer have any form of shareholder rights plan.

              The persons named in the accompanying Form of Proxy will vote such proxy in accordance with the instructions contained therein. Unless contrary instructions are specified, if the accompanying Form of Proxy is executed and returned (and not revoked) prior to the Meeting, the Common Shares represented by the Form of Proxy will be voted in favour of the Rights Plan Resolution.

The Board of Directors recommends a vote FOR the reconfirmation of the Rights Plan Resolution, as disclosed in this Information Circular and Proxy Statement.

Section 16(a) Beneficial Ownership Reporting Compliance

              Section 16(a) of the Exchange Act requires the Corporation's officers and Directors, and persons who own more than 10% of a registered class of the Corporation's equity securities, to file reports of ownership and changes in ownership with the SEC. Officers, Directors and greater than 10% beneficial owners are required by SEC regulations to furnish the Corporation with copies of all Section 16(a) reports they file.

              Based solely on a review of the reports furnished to the Corporation, the Corporation believes that during the year ended December 31, 2015, the Corporation's officers and Directors timely filed all reports they were required to file under Section 16(a), except as follows:

              On behalf of Mr. Ronan, a Form 4 reporting the grant of notional shares under the LTIP on February 23, 2015 was filed on March 16, 2015. On behalf of Mr. Palter, a Form 4 reporting the purchase of 15,000 Common Shares on August 19, 2015 was filed on December 31, 2015.

ATLANTIC POWER CORPORATION
CHARTER OF THE BOARD OF DIRECTORS

              The purpose of this charter is to set out the mandate and responsibilities of the board of directors (the "Board") of Atlantic Power Corporation (the "Issuer").

Composition

              The Board shall be constituted with a majority of individuals who qualify as "independent directors" as defined in National Policy 58-201—Corporate Governance Guidelines, applicable securities law and the relevant listing standards of the New York Stock Exchange. The Board collectively should possess a broad range of skills, expertise, industry and other knowledge, and business and other experience useful to the effective oversight of the Issuer's business and affairs.

Responsibilities of the Board of Directors

              The Board is responsible for the stewardship of the Issuer and in that regard shall be specifically responsible for:

B-1


Table of Contents

              Although the Board is called upon to "manage" the business and affairs of the Issuer, the Issuer has delegated responsibility for managerial and executive oversight and certain administrative services to the Chief Executive Officer and other senior officers of the Issuer. Reciprocally, the senior officers shall keep the Board fully informed of the progress of the Issuer and its subsidiaries towards the achievement of their established goals and of all material deviations from the goals or objectives and policies established by the Board in a timely and candid manner.

              It is recognized that every director in exercising powers and discharging duties must act honestly and in good faith with a view to the best interest of the Issuer. Directors must exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances. In this regard, they will comply with their duties of honesty, loyalty, care, diligence, skill and prudence.

              In addition, directors are expected to carry out their duties in accordance with policies adopted by the Board from time to time, the current policy being annexed hereto as Appendix "A".

B-2


Table of Contents

              It is expected that the Issuer's senior officers will co-operate in all ways to facilitate compliance by the Board with its legal duties by causing the Issuer and its subsidiaries to take such actions as may be necessary in that regard and by promptly reporting any data or information to the Board that may affect such compliance.

Responsibilities of Chair

              The role and responsibilities of the Chair of the Board are set out below:

Decisions Requiring Prior Approval of the Board of Directors

              Approval of the Board shall be required for:

              In considering related party transactions, when appropriate, the Board will review a report of an independent financial advisor in making their decision. The foregoing list is intended to specify particular matters requiring Board approval and is not intended to be an exhaustive list.

B-3


Table of Contents

Measures for Receiving Shareholder Feedback

              All publicly disseminated materials of the Issuer shall provide for a mechanism for feedback of shareholders. Persons designated to receive such information shall be required to provide a summary of the feedback to the directors on a semi-annual basis or at such other more frequent intervals as they see fit.

Meetings

              The Board will meet not less than four times per year: three meetings to review quarterly results; and one prior to the issuance of the annual financial results of the Issuer. A quorum for the meetings shall be a majority of the directors then holding office.

              From time to time directors may be asked to participate in Board retreats which may last one to three days.

Meeting Guidelines

              Directors will be expected to have read and considered the materials sent to them in advance of each meeting, and to be prepared to discuss the matters contained in such materials at the meeting. Administrative matters (e.g., bank signing resolutions, etc.) which require a vote will be batched for voting purposes. Directors will be expected to ask questions relating to batched items in advance of the meeting. The notice of meeting will highlight significant matters to be dealt with at each meeting so that directors can focus on reviewing the related materials. The senior officers of the Issuer will be made accessible to directors at Board meetings and Board committee meetings to fulfill their obligations.

Remuneration

              Remuneration shall be at a level which will attract and motivate professional and competent members.

Telephone Board Meetings

              A director may participate in a meeting of the directors or in a committee meeting by means of telephone, electronic or such other communications facilities as permit all persons participating in the meeting to communicate with each other and a director participating in such a meeting by such means is deemed to be present at the meeting.

              Although it is the intent of the Board to follow an agreed meeting schedule as closely as possible, from time to time, with respect to time-sensitive matters, telephone Board meetings may be required to be called in order for directors to be in a position to better fulfill their legal obligations. Alternatively, management may request the directors to approve certain matters by unanimous consent.

Expectations of Management

              The senior officers of the Issuer shall be required to report to the Board at the request of the Board on the performance of the Issuer, new and proposed initiatives, the Issuer's business and investments, management concerns and any other matter the Board or its Chair may deem appropriate. In addition, the Board expects the senior officers of the Issuer to promptly report to the Chair of the Board any significant developments, changes, transactions or proposals respecting the Issuer or its subsidiaries. /copyfit>

APPENDIX A
POLICY OF PRACTICES FOR DIRECTORS

Attendance at Meetings

              Each director is expected to have a very high record of attendance at meetings of the Board, and at meetings of each Board committee on which the director sits. A director is expected to:

Preparation for Meetings

              Directors are expected to carefully review and consider the materials distributed in advance of a meeting of the Board or a committee of the Board. Directors are also encouraged to contact the Chair, the Chief Executive Officer of the Issuer and any other appropriate officers to ask questions and discuss agenda items prior to meetings.

Conduct at Meetings

              Directors are expected to ask questions and participate in discussions at meetings, and to contribute relevant insights and experience. In discussions at meetings, a director should:

Knowledge of the Issuer's Business

              Directors are expected to be knowledgeable with respect to the various fields and divisions of business of the Issuer. Although the senior officers of the Issuer have a duty to keep the Board informed about developments in the Issuer's business, directors have a primary duty of care and diligence, which includes a duty of inquiry. Directors should:

Personal Conduct

              Directors are expected to:

Independent Advice

              In discharging its mandate, the Board shall have the authority to retain (and authorize the payment by the Issuer of) and receive advice from, special legal, accounting or other advisors and outside consultants if appropriate.

Other Directorships and Significant Activities

              The Issuer values the experience directors bring from other boards on which they serve and other activities in which they participate, but recognizes that those boards and activities also may present demands on a director's time and availability and may present conflicts or legal issues, including independence issues. No director should serve on the board of a competitor or of a regulatory body with oversight of the Issuer. Each director should, when considering membership on another board or committee, make every effort to ensure that such membership will not impair the director's time and availability for his or her commitment to the Issuer. Directors should advise the Chair of the Board and the Chief Executive Officer before accepting membership on other public corporation boards of directors or any audit committee or other significant committee assignment on any other board of directors, or establishing other significant relationships with businesses, institutions, governmental units or regulatory entities, particularly those that may result in significant time commitments or a change in the director's relationship to the Issuer.
