ATLANTIC POWER CORPORATION
INFORMATION CIRCULAR AND PROXY STATEMENT

              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 shareholders (the "Shareholders") of the Corporation to be held on June 20, 2014 at the Omni King Edward Hotel, Chelsea 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 30, 2014, except where otherwise noted.


Notice and Access

              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 54-104 — Proxy Solicitation from the requirement under Canadian securities laws to send paper copies of the Proxy Materials to registered and beneficial shareholders of the Corporation.


Important Notice Regarding Availability of Proxy Materials:

              The Proxy Materials are available at https://materials.proxyvote.com/04878Q. You will need to enter the 12-digit 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.

Table of Contents

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 by following the instructions provided in the Notice of Internet Availability, or, if you requested to receive printed Proxy Materials, you can also vote by telephone or 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 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 shares in accordance with New York Stock Exchange ("NYSE") rules. Generally, under current Canadian securities laws and NYSE rules, brokers will not have discretionary authority to vote such uninstructed 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 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 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

2


Table of Contents

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.


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 need not be a Shareholder of the Corporation.

              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 a.m. (Pacific time) on June 18, 2014. 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.

              A registered Shareholder of record may vote by proxy over the internet by following the instructions provided in the Notice of Internet Availability, or, if the Shareholder requested to receive printed Proxy Materials, the Shareholder can also vote by mail or telephone pursuant to instructions provided on the proxy card.

              If you hold shares through an intermediary (such as a broker, securities dealer, bank, trust company or similar entity), you may also vote by following the voting instruction form provided to you by such intermediary.

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

              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,

3


Table of Contents

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 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 the Notice of Meeting 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 at 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

4


Table of Contents

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 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 Investor Communications Solutions ("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.

              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.

              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 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 120,586,937 Common Shares outstanding.

              At the Meeting, each Shareholder of record at the close of business on April 22, 2014, 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 120,586,937 Common Shares outstanding and entitled to be voted at the Meeting.

5


Table of Contents

              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.


MATTERS TO BE CONSIDERED AT THE MEETING

MATTER 1: ELECTION OF DIRECTORS

              The number of Directors to be elected at the Meeting is six. 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. If a Director is unable to stand for election, the persons named in the enclosed Form of Proxy reserve the right to vote for another nominee at their discretion. Each nominee elected as a Director will hold office until the next annual meeting of the Shareholders or until his or her successor is elected or appointed.


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 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. 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 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 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

6


Table of Contents

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.

Table of Contents

              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 January 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.


Board Mandate

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


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 project with full opportunity for Directors to ask questions of management about any potential issues identified.


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 and Nominating and Corporate Governance Committee, all of which are comprised entirely of independent Directors, also perform oversight functions independent of management.


Position Descriptions

              Position descriptions for the Chair of the Board of Directors, the Chair of the Audit Committee, the Chair of the Nominating and Corporate Governance Committee, the Chair of the Compensation Committee and the Chief Executive Officer of the Corporation are as follows:

              To ensure the Directors exercise independent judgment 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.

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

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 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.

Audit-related fees for the year ended December 31, 2012 were for assurance and related services primarily attributable to the issuance of a comfort letter and consents in connection with securities offerings made pursuant to registration statements filed with the SEC under the Securities Act of 1933, as amended (the "Securities Act"), and a proxy statement.

              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 2013.

MATTER 3: 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 Compensation Discussion and Analysis beginning on page 33:

              Project Adjusted EBITDA and Cash Available for Distribution 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 Cash Available for Distribution are included on page 72 and page 76, respectively, of the Corporation's Annual Report on Form 10-K for the year ended December 31, 2013 filed with the SEC on February 28, 2014.

              We urge you to read the Compensation Discussion and Analysis, 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 Compensation Discussion & Analysis, 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

27


Table of Contents

executive compensation on an annual basis, and the next such advisory vote will occur at the 2015 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 2014 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.

              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 4: SPECIAL BUSINESS — APPROVAL OF AMENDMENT NO. 1 TO THE LTIP

              At the Meeting, Shareholders will be asked to consider and, if it is deemed advisable, pass the LTIP Resolution, authorizing Amendment No. 1 to the LTIP, solely to increase the aggregate number of Common Shares that may be issued under the LTIP upon the redemption of notional shares. No other changes will be made to the LTIP as a result of the LTIP Resolution. The full text of the LTIP Resolution appears in Schedule "B" of this Information Circular and Proxy Statement.

              As of April 30, 2014, the total number of notional units currently outstanding under LTIP awards is 2,193,933. The Compensation Committee has historically redeemed one-third of an award in cash, which is deposited into employees' applicable payroll tax withholding accounts and two-thirds of an award in Common Shares in order to promote stock ownership by employees, including executive officers. As a result, if the Corporation followed its historic redemption process and all notional units granted and currently outstanding under the LTIP were to vest, 1,462,476 Common Shares would be issued to participants (not including any dividend equivalent notional units (as defined below) which may accrue on such awards between now and the date of actual vesting). Out of the original 1,000,000 Common Shares approved for issuance under the current LTIP, to date, 436,356 Common Shares have been issued to participants in settlement of notional units, leaving only 563,644 Common Shares remaining to satisfy currently outstanding awards. (These numbers differ from those set forth in table headed "Securities Authorized for Issuance under Equity Compensation Plans" below primarily as a result of the SEC's disclosure requirements for such table, including a different measurement date.)

              Accordingly, unless the number of Common Shares available for issuance under the LTIP is increased, the Corporation will be required either to redeem notional shares 100% in cash (which it is permitted to do within its discretion under the LTIP), with respect to a portion of the currently outstanding notional units, or stop making grants under the LTIP. The Compensation Committee considers the LTIP to be an integral part of its overall compensation program, incentivizing employees to achieve strategic, financial and operational objectives and aligning the interests of employees directly with those of the Shareholders. In addition, a greater number of employees are now eligible to receive awards under the LTIP.

              Given the important role the LTIP plays in the compensation of eligible employees, including executive officers of the Corporation, the Shareholders are being asked to approve an increase in the maximum number of Common Shares available for issuance under the LTIP to a total of 3,000,000, thereby adding an additional 2,000,000 Common Shares. If the LTIP Resolution is approved by the Shareholders at the Meeting, a total of 2,563,644 Common Shares may be issued under the LTIP in satisfaction of currently outstanding awards (and any dividend equivalent notional units that may accrue) and pursuant to awards granted in the future. This number represents approximately 2% of Common Shares issued and outstanding as at the date hereof.

Key Terms of the Fifth Amended and Restated Long-Term Incentive Plan

              The following is a summary of the key terms of the Corporation's Fifth Amended and Restated LTIP, subject in its entirety to the terms of the LTIP itself.

              The executive officers and other employees of the Corporation are eligible to participate in the LTIP as determined by the Compensation Committee, in the case of the executive officers, and the Chief Executive Officer, in the case of the non-officer participants. Approximately 100 employees of the Corporation out of 311 total are eligible to participate in the LTIP. The purpose of the LTIP is to align the interests of employees with the long-term interests of the Shareholders by 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

29


Table of Contents

upon the achievement of strategic, financial and operational objectives critical to growing the Corporation and increasing its long-term value.

              The LTIP generally provides the Compensation Committee, as plan administrator, with the discretion to determine the extent to which executive officers and non-officer participants will receive awards under the plan, set the terms of the awards made pursuant to the plan (including the grant date), and to make exceptions in circumstances that it determines to be exceptional.

              Unless otherwise determined by the Compensation Committee, for the Corporation's executive officers, for each performance period, the Board of Directors establishes LTIP award amounts that each executive officer participant earned under the LTIP based upon the Corporation's performance against specified criteria, subject to Compensation Committee discretion. If certain levels of target performance are achieved, the executive officers become eligible to receive a grant of a number of notional shares (including fractional notional shares) to be calculated by dividing an incentive amount by the market price per Common Share (as defined below) at the time of the grant of the award.

              Unless otherwise determined by the Compensation Committee, awards for the Corporation's executive officers are based upon a combined measure of Project Adjusted EBITDA per Common Share, Free Cash Flow, Growth Cash Flow and relative TSR, each as defined in the LTIP. Up to 25% of the award may 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.

              For non-officer participants in the LTIP, at the beginning of each fiscal year, the Compensation Committee, based on the recommendation of the Chief Executive Officer, establishes a pool for LTIP awards for non-officers for that fiscal year. The size of the pool will be adjusted by a multiplier based on the Corporation's actual Net Project Cash Flow and Growth Cash Flow for the year versus the year's budget Net Project Cash Flow and Growth Cash Flow for the applicable year, each as defined in the LTIP. In determining the multiplier, the Compensation Committee also has discretion to adjust the multiplier based the Corporation's TSR for the year. After applying the multiplier to the non-officer LTIP pool, the Corporation's Chief Executive Officer, in consultation with the Corporation's other executive officers, allocates the non-officer LTIP awards to individual non-officer participants based on their performance for the year. Awards to non-officer participants are converted into a number of notional shares (including fractional notional shares) by dividing the LTIP award amount by the market price per Common Share at the time of the grant of the award.

              Unless otherwise determined by the Compensation Committee, awards to participants in the LTIP are made annually based on the performance over the applicable fiscal year and vest as to one third over each of the three years following the year of the award.

              On the applicable vesting date for notional shares held in a participant's notional share account, the Corporation generally redeems such vested notional shares as follows: (i) one third by lump sum cash payment (generally intended to be withheld toward payment of taxes that will be owed due to the vesting), and (ii) the remaining two thirds by issuance of Common Shares. Notwithstanding the foregoing, the Compensation Committee may redeem 100% of a participant's notional shares by lump sum cash payment. In addition, an executive officer may elect to redeem such notional shares for 100% Common Shares upon prior written notice of such election. All issuances of Common Shares on redemption of notional shares under the LTIP are subject to compliance with applicable securities laws.

              The market price per Common Share is defined in the LTIP as the weighted average closing price of a Common Share on the Toronto Stock Exchange for the five days immediately preceding the applicable 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 performance period

30


Table of Contents

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, to be credited in the form of additional notional shares immediately following any distribution on the Common Shares. A participant may not assign or transfer any right or interest in notional shares.

              All unvested notional shares are forfeited by a participant on the date he or she ceases to be employed by the Corporation or its subsidiaries, except in the case of death, termination without cause, disability, retirement or change of control (in certain circumstances, as described below). If the employment of a participant is terminated prior to the applicable vesting date in connection with the death of a participant, following a change of control (in the case of a change of control, where termination is by the participant for good reason or by the Corporation without cause) or by the Corporation without cause, all notional shares credited to the participant's notional share account will vest or be deemed to have vested effective the date immediately prior to the date of such termination of the participant's employment. If the employment of a participant is terminated due to the disability or retirement of the participant prior to the applicable vesting date, all notional shares credited to the participant's notional share account will vest on the vesting date as if the participant continued to be actively employed until the applicable vesting date. Notwithstanding the foregoing, if a participant in the LTIP has entered into an employment agreement with the Corporation or any of its subsidiaries, the vesting of notional shares shall be governed by the vesting provisions of such employment agreement.

              Under the LTIP, the Compensation Committee has the authority to (i) adopt rules and regulations for implementing the LTIP; (ii) determine when notional shares will be granted to eligible persons, the vesting period for each grant of notional shares and whether any adjustment(s) (performance-related or otherwise) will apply prior to vesting of any notional shares granted; (iii) adjust the size of any previously-approved pool for awards available for allocation among LTIP participants who are not officers and the membership of such non-officer group; (iv) interpret and construe the provisions of the LTIP; (v) alter or adjust any provision that is expressly provided in the LTIP in circumstances so as to operate the LTIP as objectively as possible; (vi) subject to regulatory requirements, make exceptions to the LTIP in circumstances which they determine to be exceptional; (vii) impose certain conditions at the date of grant for any notional shares, which would have to be met for an LTIP participant to be entitled to redeem notional shares granted; and (viii) make amendments to the LTIP in accordance with the amendment provisions contained therein.

              The LTIP may be amended by the Board of Directors at any time without the approval of the Corporation's security holders unless the amendment involves any increase in the number of Common Shares reserved for issuance under the LTIP, any reduction in the pricing of notional shares issuable under the LTIP or cancellation and reissue of entitlements under the LTIP, any amendment that extends the term of a grant beyond the period contemplated in the LTIP, amendments to the eligible persons under the LTIP that may permit the introduction of non-employee directors on a discretionary basis, an amendment which would permit notional shares granted under the LTIP to be transferable or assignable other than for normal estate settlement purposes, or an amendment to the plan amendment provisions. The Corporation's Fifth Amended and Restated LTIP was approved by the Compensation Committee in accordance with the above described amendment provision.

              Except with the approval of shareholders, no notional shares may be granted where such grant could result, at any time, in: (a) the number of Common Shares reserved for issuance to participants pursuant to the redemption of notional shares together with any other common share compensation arrangement exceeding 10% of Common Shares then issued and outstanding; (b) the number of Common Shares issuable to insider participants, at any time under the LTIP pursuant to the redemption of notional shares and any other common share compensation arrangements, exceeding 10% of Common Shares then issued and outstanding; or (c) the number of Common Shares issued to insider participants, within any

31


Table of Contents

one-year period, under the LTIP pursuant to the redemption of notional shares and any other common share compensation arrangements, exceeding 10% of Common Shares then issued and outstanding.

              The aggregate number of Common Shares that may be issued under the LTIP upon the redemption of notional shares is 1,000,000 Common Shares, which represents 0.8% of the issued and outstanding Common Shares as of April 28, 2014, subject to increase or decrease by reason of amalgamation, rights offerings, reclassifications, consolidations or subdivisions, or as may otherwise be permitted by applicable law and the Toronto Stock Exchange. The total number of Common Shares issued under the LTIP upon the redemption of notional shares granted under the LTIP is 436,356, which represents 0.4% of the issued and outstanding Common Shares as of April 28, 2014. The total number of Common Shares that remain issuable under the LTIP is 563,644, which represents 0.4% of the issued and outstanding Common Shares as of April 28, 2014.

              The only effect of the LTIP Resolution will be to increase the aggregate number of Common Shares that may be issued under the LTIP upon the redemption of notional shares. Because the grant of awards under the LTIP is within the discretion of the Compensation Committee, the Corporation cannot determine the dollar value or number of Common Shares that will in the future be received by or allocated to any participant in the LTIP. As of April 28, 2014, the closing price of a Common Share of the Corporation on the New York Stock Exchange was $3.22 and on the TSX was C$3.56.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Introduction

              The following Compensation Discussion and Analysis ("CD&A") describes the Corporation's compensation policies and practices as they relate to our executive officers included in the Summary Compensation Table below (the "named executive officers"). The Corporation's named executive officers for 2013 were Barry E. Welch, our President and Chief Executive Officer; Terrence Ronan, our Executive Vice President — Chief Financial Officer; Paul H. Rapisarda, our Executive Vice President — Commercial Development; and Edward Hall, our Executive Vice President — Chief Operating Officer (effective April 2, 2013).

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 and retain key individuals. Compensation plays an important role in achieving short and long-term business objectives that ultimately drive business success in alignment with long-term Shareholder goals. The objectives of the Corporation's compensation program are to:

              The Corporation's compensation program is designed to provide competitive rewards for services and incentive for its senior management team to implement both short-term and long-term strategies aimed at increasing Shareholder value and aligning the interests of senior management with those of the Shareholders, while minimizing incentives to engage in high-risk business strategies.

              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 employees. In designing the compensation program, the Board of Directors focuses on remaining competitive in the market with respect to total compensation for each of the named executive officers. However, the Board of Directors does review each element of compensation for market competitiveness and it 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. Mr. Welch was involved in making recommendations to the Compensation Committee regarding compensation for Mr. Ronan, Mr. Rapisarda and Mr. Hall.


2013 Say-on-Pay Vote

              At the Corporation's Annual Meeting of Shareholders held on June 21, 2013, 70.99% 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 2013 Information Circular and Proxy Statement voted in favour of the proposal. The Compensation Committee believes this strong affirmative vote affirms Shareholders' support of the Corporation's approach to executive compensation. The Compensation

34


Table of Contents

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.


Elements of Executive Compensation

              The compensation of each named executive officer 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.


Base salary

              The base salaries for the named executive officers for 2013 were based on a review by the Compensation Committee. This review was based on the level of responsibility, the experience level attained by the relevant named executive officer, competitive salaries for similar positions in the market, and his personal contribution to the Corporation's operating and financial performance with a goal of ensuring that the base salaries are appropriate and competitive.

              Barry E. Welch.    Since 2004, Mr. Welch has been the President and Chief Executive Officer of the Corporation (until December 31, 2009, through the Manager). Mr. Welch's salary was $700,000 for 2013 based on his critical role in achieving the Corporation's goals and objectives. The Compensation Committee determined that there would be no change in Mr. Welch's salary for 2014.

              Terrence Ronan.    On August 20, 2012, Terrence Ronan became the Corporation's Executive Vice President — Chief Financial Officer and Corporate Secretary with an annual base salary of $375,000. The Compensation Committee determined that Mr. Ronan's salary would be increased to $400,000 for 2014 based on a review of peer company data as well as Mr. Ronan's accomplishments.

              Paul H. Rapisarda.    Beginning in 2011, Mr. Rapisarda became the Corporation's Executive Vice President — Commercial Development. Mr. Rapisarda's salary was increased to $425,000 for 2013. The Compensation Committee determined that there would be no change in Mr. Rapisarda's salary for 2014.

              Edward C. Hall.    On April 2, 2013, Ned Hall became the Corporation's Executive Vice President — Chief Operating Officer with an annual base salary of $425,000. The Compensation Committee determined that there would be no change in Mr. Hall's salary for 2014.


Short-term incentive plan (non-equity incentive plan compensation)

              Beginning for performance year 2012 and beyond, the Compensation Committee developed and approved the Corporation's short-term incentive plan ("STIP") to determine the cash awards payable to Barry E. Welch, Terrence Ronan, Paul H. Rapisarda and Edward C. Hall. Payouts under the STIP are included in the column identified as "Non-equity incentive plan compensation" in the Summary Compensation Table on page 45. 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, but with individual weightings assigned to each measure. Under the STIP, the performance of

Project Adjusted EBITDA is defined for purposes of the STIP as earnings before interest, taxes, depreciation and amortization ("EBITDA") from consolidating and equity accounted projects, including Project Adjusted EBITDA from projects that, after January 1, 2013, have been classified as held for sale or as discontinued operations. The EBITDA from equity accounted projects represents the Corporation's ownership percentage in the projects. Cash Flow from Projects is defined as distributions and management fees received from projects.

              In February 2014, the Compensation Committee determined that the named executive officers were eligible for annual incentive awards under the pre-established performance criteria. The Compensation Committee made these awards in consultation with Hugessen Consulting based primarily on the achievements of the Corporation relating to the four measures above. In exercising its discretion under the STIP, the Compensation Committee also decided not to pay the full amounts allowable under

Performance of Existing Portfolio

  The Corporation had a strong year with regards to the operational performance of the plants with a Project Adjusted EBITDA of $270.5 million versus guidance of $250 — $275 million. Cash Flow from Projects was $225.5 million versus a target of $214.7 million. Almost all of the approved 2013 commercial and operating goals were met.     25 % 21.75%

Growth

 

The Corporation originally envisioned investing cash available in the second half of 2013, which was later targeted for debt reduction. Instead, by year-end 2013, the Corporation spent $10 million and committed to spend an additional $10 million in 2014 for organic growth investments with a projected cash flow increase totaling approximately $8 million/year, below the Corporation's original expectations. With an internal focus on integration, the Corporation successfully completed the Ridgeline transition to Atlantic Power and reduced associated G&A.

Financial & Risk Management

 

There were no capital raises in 2013 and the Corporation was unable to broaden its investor base. All of the Corporation's risk management objectives were achieved and it was able to expand its analyst coverage although commentary on share performance deteriorated over the period.

              For the STIP award paid in 2014 based on the 2013 performance year, the decision was made not to make an award to Mr. Welch. This was done to maintain a strong compensation plan link between the Shareholders and the compensation of the CEO.

              For the STIP award paid in 2014 based on the 2013 performance year, Mr. Ronan's award was determined to be $170,000 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.

              For the STIP award paid in 2014 based on the 2013 performance year, Mr. Rapisarda's award was determined to be $190,000 based on the Compensation Committee's review of the components of the STIP, including the review of certain subjective factors. In particular, Mr. Rapisarda contributed to the Corporation's achievement of its goals described above in the area of growth.

              For the STIP award paid in 2014 based on the 2013 performance year, Mr. Hall's award was determined to be $160,000 based on the Compensation Committee's review of the components of the STIP, including the review of certain subjective factors, and prorated to take into account the date he joined the Corporation. In particular, Mr. Hall contributed to the Corporation's achievement of its goals described above in the areas of performance of existing portfolio.

Long-Term Incentive Plan

              The named executive officers and other employees of the Corporation are eligible to participate in the Corporation's Fifth Amended and Restated 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 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.

              Under the LTIP as revised, awards for the Corporation's executive officers are based upon a combined measure of Project Adjusted EBITDA per Common Share (as defined below for purposes of the LTIP, based on shares outstanding), Free Cash Flow (as defined below), Growth Cash Flow (as defined below) and relative Total Shareholder Return ("TSR"). Up to 25% 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 as 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 four performance measures, the Compensation Committee also looks at TSR in the context of the entire award to ensure alignment.

              Project Adjusted EBITDA per Common Share means, for purposes of the LTIP, project income plus interest, taxes, depreciation and amortization (including non-cash impairment charges), including Project Adjusted EBITDA from projects that, after the first date of the specified calendar year, have been

Table of Contents

classified as held for sale or as discontinued operations, and changes in fair value of derivative instruments. Free Cash Flow is defined as the Corporation's cash flow before distributions and dividends. Growth Cash Flow is defined as forecasted annual cash flow from acquisitions made during the fiscal year and as appropriate, increased cash flow from CAPEX projects within the existing fleet. 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 were reinvested. For 2013, 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:

              On the applicable vesting date for notional shares held in a participant's notional share account, the Corporation redeems such vested notional shares as follows: (i) one-third by lump sum cash payment (generally deposited into the participant's applicable payroll tax withholding account), and (ii) the remaining two-thirds by an exchange for Common Shares. Notwithstanding the foregoing, a named executive officer may elect to redeem such notional shares for 100% common shares upon prior written notice of such election. All issuances of Common Shares on redemption of notional shares under the LTIP are subject to compliance with applicable securities laws.

              For each performance period, the Board of Directors establishes LTIP award amounts that each executive officer participant 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 (including fractional units) 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 US 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 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, to be credited in the form of additional notional shares immediately following any distribution on the Common Shares.

Table of Contents

              The LTIP generally provides the Compensation Committee, as plan administrator, with the discretion to determine the extent to which executive officers will receive awards under the plan, set the terms of the awards made pursuant to the plan (including the grant date), and to make exceptions in circumstances that it determines to be exceptional. The Board of Directors determined not to grant awards in 2013 in respect of the 2012 performance year, but rather to grant discretionary awards of notional shares with an initial award amount of $200,000 (41,237 notional shares) and $100,000 (20,619 notional shares) to Paul H. Rapisarda, Executive Vice President — Commercial Development, and Terrence Ronan, Executive Vice President — Chief Financial Officer, respectively, with vesting based on corporate performance results in a three-year period. The Board of Directors also determined to make no 2013 long-term incentive award in respect of the 2012 performance year to Mr. Welch, after taking into account his recommendation that he receive no award.

              In addition, in order to more closely align Mr. Ronan's interest with those of the Corporation and its Shareholders and in connection with his engagement as Chief Financial Officer, on April 11, 2013, the Compensation Committee approved a grant of 6,000 notional shares to Mr. Ronan. On April 2, 2014, as part of the compensation package the Corporation offered to Mr. Hall upon his appointment as Executive Vice President — Chief Operating Officer of the Corporation, the Compensation Committee approved a grant to Mr. Hall of notional shares with a value of $180,000, which resulted in a grant of 36,961 notional shares.

              Each of these grants is described in more detail in the "Compensation Discussion and Analysis" in the Information Circular and Proxy Statement for the Corporation's 2013 Annual and Special Meeting of Shareholders.

              For 2013, the possible quantum of awards under the LTIP ranged from zero to a cap of $2.8 million for the Chief Executive Officer and $1.5 million for the Executive Vice President — Chief Financial Officer, Executive Vice President — Chief Operating Officer and Executive Vice President — Commercial Development. For 2013, the midpoint targets for each of the four performance measures were set as follows: (1) Project Adjusted EBITDA per Common Share — $2.18 to $2.23; (2) Free Cash Flow — $91.1 million to $93.9 million; (3) Growth Cash Flow — $12 million to $15 million; and (4) relative TSR — 56th to 65th percentile. If each of these target ranges were achieved in 2013, the recommended award for our Chief Executive Officer would be $1.5 million and for our Executive Vice President — Chief Financial Officer, Executive Vice President — Chief Operating Officer and our Executive Vice President — Commercial Development would be $750,000.

              The following table indicates the thresholds established for each performance measure under the LTIP for 2013 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 25% 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.

              In 2013, the Corporation's TSR of -64.1% was in the bottom quartile of the Corporation's TSR Peer Group, as calculated by Factset.

              The Compensation Committee determined to make the following awards on February 27, 2014 for the 2013 performance year. The Compensation Committee made these awards in consultation with Hugessen Consulting based primarily on the achievements of the Corporation relating to the four measures above and also by exercising its discretion under the LTIP. The notional shares awarded will each vest as to one third over each of the three years following the year of the award, subject to continued employment of the officer.

              Mr. Welch received a grant of $600,000 or 227,273 notional shares, which represents approximately 21% of the maximum quantum of the award available under the LTIP and approximately 50% of the quantum of the award that would have been granted based on the actual LTIP performance measures described above.

              Mr. Rapisarda received a grant of $350,000 or 132,576 notional shares, which represents approximately 23% of the maximum quantum of the award available under the LTIP and approximately 50% of the quantum of the award that would have been granted based on the actual LTIP performance measures described above..

              Mr. Ronan received a grant of $350,000 or 132,576 notional shares which represents approximately 23% of the maximum quantum of the award available under the LTIP and approximately 50% of the quantum of the award that would have been granted based on the actual LTIP performance measures described above..

              Mr. Hall received a grant of $275,000 or 104,167 notional shares which represents approximately 18% of the maximum quantum of the award available under the LTIP, prorated based on Mr. Hall joining the Corporation in April 2013, and approximately 50% of the quantum of the award that would have been granted based on the actual LTIP performance measures described above.

              The Compensation Committee 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:

              These awards will be reported in the Summary Compensation Table in the Information Circular and Proxy Statement for the Corporation's 2015 Annual Meeting of Shareholders.


Performance-Based Vesting or Forfeiture of Shares

              In addition, as described in the Corporation's Information Circular and Proxy Statement for the year ended December 31, 2010, notional shares were granted to senior executives under the LTIP in 2010 that would vest at the end of a three-year performance period (2010-2012) based on the Corporation's TSR compared to a group of peer companies during such period. Each of Mr. Welch and Mr. Rapisarda received a grant of notional shares in 2010 in an amount equal to his base salary. Depending upon the Corporation's performance, subject to the discretion of the Compensation Committee, the grants would vest at the end of the three-year performance period in an amount ranging from 0% up to a maximum of 150% of the sum of notional shares initially granted plus dividend equivalent rights received during the performance period. Based upon the Corporation's TSR during the performance period and the Compensation Committee's exercise of its discretion, 100% of the units were forfeited. For Barry Welch this resulted in a forfeiture of 49,185 units and for Paul Rapisarda it resulted in a forfeiture of 26,517 units.


Employment Agreements

              Effective April 15, 2013, in accordance with the terms of their respective offer letters, the Corporation entered into an employment agreement with each of Terrence Ronan and Edward C. Hall. On the same date, the Corporation entered into amended employment agreements with Barry E. Welch and Paul H. Rapisarda, which replace their respective prior employment agreements dated December 31, 2009.

              Each of the employment agreements provides the respective executive officer 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 Corporation's Fifth Amended and Restated 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. Mr. Welch is also entitled to term life insurance coverage for a total of twice his annual salary. Each employment agreement has an initial three-year term ending on March 31, 2016. Beginning in 2014, on January 1 of each year the three-year employment agreements extend automatically for an additional one-year term unless notice is given by the Corporation or the officer that the agreement will not be renewed.

              In addition, under each of the executive officers' employment agreements, each executive officer agrees 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

Table of Contents

awards granted to an 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.

              The employment agreements also contain 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 other gross-ups for the benefit of our executive officers.


Retirement Benefits

              The Corporation does not sponsor a defined benefit retirement plan for any of its employees. In addition, the Corporation does not provide 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 the named executive officer's personal savings toward future retirement as the Corporation has no other pension plan for them. The matching for the named executive officers is a dollar-for-dollar match with the 401(k) contributions, up to the maximum allowed by Internal Revenue Service ("IRS") regulations. The IRS maximum contribution in 2013 was $17,500 for participants under age 50 and $23,000 for participants 50 and over.


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 and directors (the "Director and Executive Officer Share Ownership Policy" or "Policy") in order to further align the interests of the Corporation's key executives with the long-term interests of the Shareholders. The Policy provides that on or before December 31, 2015 (for the current named executive officers) or within five years of their appointment (for any newly appointed officer in the designated positions), each officer will be required to acquire, and thereafter maintain, ownership of a number of Common Shares with a minimum fair market value equal to the multiple of such executive officer's annual base salary (excluding bonus), as follows:

President and Chief Executive Officer

  Three times annual base salary

Executive Vice President — Chief Financial Officer

  Two times annual base salary

Executive Vice President — Chief Operating Officer

  Two times annual base salary

Executive Vice President — Commercial Development

  Two times annual base salary

              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

Table of Contents

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 set out above, 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 as a result, the grace period under the Policy, as described above, is still in effect.


Compensation Committee Report

              The Compensation Committee of the Board of Directors of the Corporation has reviewed and discussed the 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 Compensation Discussion and Analysis 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 each of Barry E. Welch, Terrence Ronan, Paul H. Rapisarda and Edward C. Hall provides that if the respective executive officer 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

47


Table of Contents

lump sum termination payment equal to three times the average (in the case of Mr. Welch) or two times the average (in the case of Mr. Ronan, Mr. Rapisarda and Mr. Hall), 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 two years (in the case of Mr. Welch) or one year (in the case of Mr. Ronan, Mr. Rapisarda and Mr. Hall) 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. 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.

              On August 30, 2013, the Corporation entered into an addendum to the employment agreements of each of Mr. Hall and Mr. Ronan which clarifies the calculation of the executive officer's Total Annual Compensation in cases where the executive has been employed with the Corporation for less than two years. Pursuant to the addendum, for a termination prior to the approval of the executive officer's first annual bonus award, the executive officer's average Total Annual Compensation is equal to the sum of the current annual base salary, an annual bonus calculated at 75% of current base salary and the Corporation's most recent annualized 401(k) matching contribution contributed on the executive officer's behalf. For a termination after the approval of the executive officer's first annual bonus award but prior to the approval of his second annual bonus award, the executive officer's average Total Annual Compensation is equal to the average of (i) the sum of the executive officer's annual base salary in effect with respect to the executive officer's first year of service, the actual first annual bonus percentage approved for the executive officer multiplied by the executive officer's annual base salary in effect with respect to the executive officer's first year of service and the Corporation's most recent annualized 401(k) matching contribution contributed on the executive officer's behalf and (ii) the sum of executive officer's current annual base salary, an annual bonus calculated at 75% of current base salary and the Corporation's most recent annualized 401(k) matching contribution contributed on the executive officer's behalf.

              The employment agreements also contain non-competition and non-solicitation limitations on each of the executive officers following certain termination events. The non-competition restrictions apply for a period of one year (in the case of Mr. Welch) or six months (in the case of Mr. Ronan, Mr. Rapisarda and Mr. Hall) following termination by the Corporation for unsatisfactory performance or by the executive officer in the context of a change in control as described above, or a period of one month (for each executive officer) following resignation by the executive officer for any other reason or termination by the Corporation for cause. The non-solicitation restrictions apply for a period of two years (in the case of Mr. Welch) or one year (in the case of Mr. Ronan, Mr. Rapisarda and Mr. Hall) following the date of termination.

              In each executive officer's employment agreement, the term "Change in Control" means 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. ("Atlantic Holdings"), directly or indirectly, which assets generated more than 50% of the Atlantic Holdings' 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 Corporation's or Atlantic Holdings' liquidation or dissolution; (iii) the acquisition by any person or group of a direct or indirect interest in more than 50% of the Corporation's Common Shares or voting power or Atlantic Holdings' common membership interests or voting power; (iv) the Corporation's or Atlantic Holdings' merger or consolidation with another person with the effect that immediately after such transaction Shareholders or holders of common membership interests in Atlantic Holdings immediately prior to such transaction hold, directly or indirectly, less than 50% of the voting control over the person surviving such merger or consolidation; or (v) the Corporation, Atlantic Holdings or any of their Shareholders or members enter into any agreement providing for any of the foregoing, or the date which is 90 days prior to a definitive announcement of any of the foregoing whichever is earlier, and the transaction contemplated thereby is ultimately consummated.

Table of Contents

              If Mr. Welch, Mr. Ronan, Mr. Rapisarda or Mr. Hall is terminated for cause, then he will be entitled to his base salary through the termination date, to the extent not yet paid, and all vested benefits under all incentive compensation or other plans in accordance with the terms and conditions of such plan; however, he will not be entitled to the payments or benefits listed in items (ii) through (v) in the second preceding paragraph above, except as may be required by applicable law. "Cause" is defined in each executive officer's employment agreement as a termination by reason of the Corporation's good faith determination that the executive (i) engaged in willful misconduct in the performance of his duties, (ii) breached a fiduciary duty to the Corporation for personal profit to himself, (iii) after determination by a court of competent jurisdiction, willfully violated any law, rule or regulation of a governmental authority with jurisdiction over the executive officer or the Corporation at the time and place of such violation (other than traffic violation or similar offenses) or any final cease and desist order of a court or other tribunal of competent jurisdiction, or (iv) materially and willfully breached such agreement. No act, or failure to act, on the executive officer's part shall be considered "willful" unless he has acted, or failed to act, with an absence of good faith and without a reasonable belief that this action or failure to act was in the best interest of the Corporation.

              In the event that Mr. Welch, Mr. Ronan, Mr. Rapisarda or Mr. Hall are, by reason of illness or incapacity, unable to fulfill their obligations on behalf of the Corporation for a period of 90 consecutive days, the Corporation's long-term disability group coverage will pay the executive officer up to 60% of his base salary, subject to its terms and conditions. The Corporation provides term life insurance coverage in accordance with its group policy, except that, in the case of Mr. Welch, the Corporation shall provide term life insurance coverage for a total of twice his annual salary.

              If Mr. Welch, Mr. Ronan, Mr. Rapisarda or Mr. Hall retire at the age of sixty-two or thereafter, any unvested notional shares awarded under the LTIP held by him will continue to vest in accordance with the provisions of the LTIP in effect at the date of retirement.

              The following table provides, for each of the Corporation's named executive officers as of December 31, 2013, an estimate of the payments payable by us, assuming a termination for any reason other than cause, including the occurrence of the triggering events described above. The amounts shown assume that such termination was effective as of December 31, 2013 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

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.

Compensation of Directors

Director Fees

              Each independent Director is entitled to receive an annual retainer of $50,000, plus $10,000 of value in deferred share units ("DSUs") and $1,500 per meeting attended in person or $1,000 per meeting attended by phone. The Chair of the Board of Directors, including for his responsibilities as Chair of the Nominating and Corporate Governance Committee, Chair of the Audit Committee and Chair of the Compensation Committee receive an additional $35,000, $15,000 and $10,000 per year, respectively. Directors are reimbursed for out-of-pocket expenses for attending meetings. Directors also participate in insurance and indemnification arrangements.


Share Ownership Policy

              On April 1, 2013, the Board of Directors adopted the Director and Executive Officer Share Ownership Policy, which superseded the policy applicable to independent directors adopted on April 24, 2007, in order to 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 January 1, 2014, the per share value was $4.17. As of April 30, 2014, all Directors subject to the Policy were within the Policy's one-year grace period applicable in the event of a decline in the price of the Corporation's Common Shares by 25% or more in any year.


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 so long as the participant continues to serve on the Board of Directors, dividends 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

51

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, 2013. Directors who are also executive officers of the Corporation are not entitled to any compensation for their services as a Director.

MANDATE OF THE BOARD OF DIRECTORS


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:

A-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".

              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

A-2


Table of Contents

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.

A-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.

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.
