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 21, 2013 at Vancouver Marriott Pinnacle Downtown Hotel, Ambleside Room, 1128 West Hastings Street, Vancouver, British Columbia, Canada commencing at 10:00 a.m. (Pacific 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     , 2013, except where otherwise noted.

              This Information Circular and Proxy Statement is being first mailed to Shareholders on or about May 10, 2013. In accordance with the requirements of National Instrument 54-101 — Communication with Beneficial Owners of Securities of a Reporting Issuer, for purposes of distributing to non-registered Shareholders who have requested a copy, the Corporation has distributed copies of this Information Circular and Proxy Statement to the intermediaries for onward distribution to such non-registered Shareholders.


Important Information Regarding the Availability of Proxy Materials

              The Corporation's Information Circular and Proxy Statement and annual report for the year ended December 31, 2012 ("Annual Report") are available free of charge at http://materials.proxyvote.com/04878Q.

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.

3


Table of Contents

              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 by mailing the accompanying form of proxy ("Form of Proxy") 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 proxies may also be solicited personally, in writing or by telephone by employees of the Corporation, at nominal cost. The Corporation will bear the cost in respect of the solicitation of proxies for the Meeting and will bear the legal, printing and other costs associated with the preparation of the Information Circular and Proxy Statement. In addition, MacKenzie Partners, Inc. ("MacKenzie") has been retained to assist in the solicitation of proxies for the Meeting at a fee of approximately $20,000, plus associated costs and expenses. MacKenzie will provide advisory and solicitation services to the Corporation in connection with the Meeting.

Appointment and Revocation of Proxies

              Together with the Information Circular and Proxy Statement, the Shareholders will also be sent 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"), 9th 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 19, 2013. 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.

4


Table of Contents

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

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

Voting of Proxies

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

5


Table of Contents

              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 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

6


Table of Contents

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                        Common Shares outstanding.

              At the Meeting, each Shareholder of record at the close of business on April 23, 2013, the record date established for the Notice of Meeting and for voting at the Meeting (the "Record Date"), will be entitled to one vote for each Common Share held on all matters proposed to come before the Meeting. At the close of business on the Record Date, there were                        Common Shares outstanding and entitled to be voted at the Meeting.

              To the knowledge of the Board of Directors, there are no persons that beneficially own or exercise control or direction over Common Shares carrying approximately 10% or more of the votes attached to the issued and outstanding Common Shares, except BlackRock, Inc., which beneficially owns 10.56% of the Common Shares based on the Schedule 13G filed on April 10, 2013 with the Securities and Exchange Commission (the "SEC"). 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

7


Table of Contents

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.

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

              The Corporation does not have a policy of requiring its Directors to attend the annual general meeting of Shareholders. The Chair of the Board of Directors is expected to attend and chair meetings of the Shareholders. Five of six Directors then serving attended the annual meeting held on June 22, 2012.

              It is expected that the Board of Directors will meet at least 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.

Table of Contents


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:

Orientation and Continuing Education

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


Ethical Business Conduct

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

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

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

Table of Contents

              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. Any waivers from the requirements in the Codes that are to be granted for the benefit of the Directors, managers or executive officers of the Corporation are to be granted by the Directors only (or a committee of the Board of Directors to whom that authority has been delegated) and will be promptly disclosed as required by law or stock exchange regulation.

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

              The Codes are available on the Corporation's website at www.atlanticpower.com under "ABOUT US — Code of Conduct" and under the Corporation's profile on the System of Electronic Document Analysis and Retrieval ("SEDAR") at www.sedar.com.

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


Audit Committee

              The Corporation has established an audit committee consisting of Messrs. Gerstein, Hartwick, McNeil and Duncan and Ms. Ladhani, each of whom is an independent Director under the NYSE corporate governance rules. The committee's primary purposes are to, among other things: (i) assist the Board of Directors in its oversight and supervision of the integrity of the accounting and financial reporting practices and procedures, the implementation and adequacy of the internal accounting controls and procedures and the compliance with legal and regulatory requirements in respect of financial disclosure; (ii) assess and monitor the strategic, operating, reporting and compliance risks of the business; and (iii) supervise the qualification, independence and performance of independents accountants of the Corporation.

              In accordance with the mandate of the Board of Directors, the Board of Directors periodically evaluates the composition of the committees, and, together with the Audit Committee, in accordance with the AC Charter, has appointed Holli Ladhani to replace Kenneth M. Hartwick as Chair of the Audit Committee as of April 1, 2013 in an effort to more efficiently allocate responsibilities among the members of the Board of Directors and to allow Mr. Hartwick to focus on his responsibilities as the Chair of the Compensation Committee. The Board of Directors has determined that Ms. Ladhani qualifies as an "audit committee financial expert" as the term is defined in the rules of the SEC. Ms. Ladhani is an independent Director.

              The Audit Committee met four times during 2012.

Nominating and Corporate Governance Committee

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

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

              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"

27


Table of Contents

provisions of Section 10A(i)(1)(B) of the Exchange Act are satisfied. There were no services provided under the "de minimis" provisions in 2012. The authority to pre-approve non-audit services may be delegated to one or more members of the Audit Committee, who shall present all decisions to pre-approve an activity to the full Audit Committee at its first meeting following such decision.

The Audit Committee recommends a vote FOR the appointment of KPMG LLP as the auditors of the Corporation and the authorization of the Corporation's Board of Directors to fix such auditor's remuneration.

MATTER 3: SPECIAL BUSINESS — NON-BINDING ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION

              We believe that we have the right executive team in place to implement our business strategy, and 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 41:

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

29


Table of Contents


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 2013 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 THE RIGHTS PLAN

Shareholders' Rights Plan

              The Corporation adopted and entered into the Rights Plan with Computershare Investor Services Inc., as Rights Agent, on February 28, 2013. The purpose of the Rights Plan is to provide the Board of Directors and Shareholders with more than the 35 days currently required under Canadian securities laws to consider any take-over bid made for the Corporation and to allow enough time for competing bids and alternative proposals to emerge. The Rights Plan also seeks to ensure that all Shareholders are treated fairly in any transaction involving a change of control of the Corporation and that all Shareholders have an equal opportunity to participate in the benefits of a take-over bid. The Rights Plan encourages potential acquirers to make a Permitted Bid (as defined in the Rights Plan) or, alternatively, to negotiate the terms of any offer for Common Shares with the Board of Directors. The Rights Plan also addresses deficiencies that are widely believed to be inherent in the provisions of current legislation governing take-over bids in Canada. The Board of Directors believes that it is in the Shareholders' interests to address these deficiencies through the mechanisms in the Rights Plan. These deficiencies are described in greater detail below.

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


Background

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


Time to Consider Bid

              Under current Canadian securities legislation, the minimum period that a take-over bid must remain open for acceptance is 35 days. The Board of Directors is of the view that 35 days constitutes an

31


Table of Contents

insufficient amount of time to permit the Directors and Shareholders to assess an offer, and to allow the Directors to negotiate with the offeror, solicit competing offers, consider alternative transactions, and otherwise take the actions appropriate in the circumstances. The Rights Plan gives the Board of Directors and Shareholders more time to consider a take-over bid by requiring an offeror to make a "Permitted Bid" if it wishes to proceed without negotiating with the Board of Directors and without triggering the Rights Plan. In order to qualify as a Permitted Bid, the bid must meet certain minimum conditions. A Permitted Bid must, among other things, be open for at least 60 days and must remain open for a further period of 10 business days after the offeror publicly announces that more than 50% of the outstanding Common Shares held by Independent Shareholders (as defined below) have been deposited or tendered and not withdrawn. "Independent Shareholders" include all holders of Common Shares other than (i) a person who is the beneficial owner of 20% or more of the Common Shares subject to certain exceptions (an "Acquiring Person"), (ii) any offeror making a take-over bid, (iii) any affiliate or associate of an Acquiring Person or offeror, (iv) persons acting "jointly or in concert" with an Acquiring Person or offeror, and (v) a plan or trust for the benefit of employees of the Corporation or a subsidiary of the Corporation, unless the beneficiaries of such plan or trust direct the manner in which the Common Shares are to be voted or withheld from voting or direct whether or not the Common Shares are to be tendered to a take-over bid.


Pressure to Tender

              A Shareholder may feel compelled to tender to a take-over bid that the Shareholder considers to be inadequate because, in failing to tender, the Shareholder may be left with illiquid or minority discounted Common Shares. The Rights Plan contains a Shareholder approval mechanism in the Permitted Bid definition, which is that no Common Shares may be taken up and paid for under the bid unless more than 50% of the outstanding Common Shares held by Independent Shareholders have been deposited or tendered and not withdrawn. In addition, a Permitted Bid must remain open for acceptance for a further period of 10 business days following public announcement that more than 50% of the outstanding Common Shares have been deposited. The Rights Plan therefore helps to separate a Shareholder's decision to accept a bid from the decision to tender, thereby lessening concern about undue pressure to tender to the bid. At the same time, the Rights Plan does not prohibit partial bids.


Unequal Treatment of Shareholders

              Under current Canadian securities legislation, an offeror may obtain control or effective control of a company without paying full value, without obtaining Shareholder approval and without treating all Shareholders equally. For example, an acquirer could acquire blocks of shares by private agreement from one or a small group of Shareholders at a premium to market price, which premium is not shared by the other Shareholders. In addition, a person could slowly accumulate Common Shares through stock exchange acquisitions that may result, over time, in an acquisition of control or effective control without paying a control premium or fair sharing of any control premium among Shareholders. Under the Rights Plan, if it is to qualify as a Permitted Bid, any offer to acquire 20% or more of the Corporation's Common Shares must be made to all holders of Common Shares, other than the Person who is making or has announced a current intention to make a Takeover Bid.

              A copy of the Rights Plan will be available for inspection by Shareholders at the Corporation's records office during statutory business hours on the five business days immediately preceding the Meeting. The following is a summary of the principal terms and conditions of the Rights Plan. The summary is qualified in its entirety by the complete text of the Rights Plan which was filed on SEDAR at www.sedar.com and as Exhibit 4.1 to the Corporation's Current Report on Form 8-K on March 1, 2013 on Electronic Data Gathering, Analysis and Retrieval ("EDGAR") at www.sec.gov/edgar.shtml.

Summary

              On February 28, 2013, pursuant to the Rights Plan, one common share purchase right (individually, a "Right" and, collectively, the "Rights") was issued for each outstanding Common Share to Shareholders of record at the close of business on March 11, 2013 (the "Record Time"). One Right will also be issued in respect of each Common Share issued thereafter, subject to the limitations set forth in the Rights Plan. The Rights Plan will utilize the mechanism of the "Permitted Bid" (as described below) to ensure that a person seeking control of the Corporation gives Shareholders and the Board of Directors sufficient time to evaluate the bid, negotiate with the initial bidder and encourage competing bids to emerge. The purpose of the Rights Plan is to protect Shareholders by requiring all potential bidders to comply with the conditions specified in the Permitted Bid provisions or else such bidders are subject to the dilutive features of the Rights Plan.

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

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

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

33


Table of Contents

Grandfathered Person immediately at such time as such person ceases to be the beneficial owner of 20% or more of the voting shares then outstanding.

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

              A "Permitted Bid" is a take-over bid where the bid is made by way of a take-over bid circular to all registered holders of the Corporation's voting shares, other than the offeror, and the bid is subject to irrevocable and unqualified conditions (and only so long as all the conditions are met) that (i) no voting shares shall be taken up or paid for prior to the close of business on a date which is not less than 60 days after the date of the take-over bid and then only if more than 50% of the outstanding voting shares held by Independent Shareholders (as defined below) have been deposited or tendered pursuant to the take-over bid and not withdrawn, (ii) voting shares may be deposited pursuant to the take-over bid (unless the take-over bid is withdrawn) at any time prior to the date on which voting shares are first taken up and paid for under the take-over bid and may be withdrawn until taken up and paid for, and (iii) if on the date on which voting shares may be taken up and paid for, more than 50% of the voting shares held by Independent Shareholders have been deposited or tendered pursuant to the take-over bid and not withdrawn, that fact will be publicly announced by the offeror and the take-over bid will be extended for at least 10 business days following such announcement.

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

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

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

Certificates and Transferability

              The Rights Plan provides that, until the Separation Time, the Rights may be transferred with and only with the Common Shares and certificates for Common Shares will evidence one Right for each Common Share represented by the certificate. Certificates for Common Shares issued after the Record Time shall bear a legend stating that each certificate also represents one Right. Promptly after the Separation Time, separate certificates evidencing the Rights ("Right Certificates") will be mailed to holders of record of Common Shares as of the Separation Time (other than an Acquiring Person and other excluded persons pursuant to the terms of the Rights Plan). Such separate Right Certificates alone will

34


Table of Contents

evidence the Rights. Until a Right is exercised, the holder thereof, as such, will have no rights as a shareholder of the Corporation, including no right to vote or to receive dividends.

Redemption, Waiver and Amendment

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

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

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

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

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

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

35


Table of Contents

Directors and with the prior consent of the majority of the holders of the Rights (other than an Acquiring Person or other holder as excluded by the terms of the Rights Plan), supplement or amend the Rights Plan and the Rights (whether or not such action would materially adversely affect the interests of the holders of the Rights generally).

Term

              The Rights Plan will remain in effect until the earlier of (a) the date of termination of Meeting, and (b) six months from the effective date of the Rights Plan, if the Rights Plan is not confirmed by a majority of the Independent Shareholders at the Meeting. If confirmed at the Meeting, the Rights Plan must be reconfirmed at every third annual meeting following the Meeting, or the Rights Plan and the Rights will otherwise terminate on the date of the meeting if the Rights Plan is not reconfirmed or presented for reconfirmation. Notwithstanding the foregoing, the Rights will terminate on the close of business on February 28, 2023.


Effect of Rights Plan

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


Shareholder Approval

              In order for the resolution ratifying the Rights Plan to be effective, at least a majority of the votes cast by Shareholders present in person or represented by proxy at the Meeting must be voted in favour of the Rights Plan Resolution.

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

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

MATTER 5: SPECIAL BUSINESS — CONFIRMATION AND APPROVAL OF ADVANCE NOTICE POLICY

Background

              On April 1, 2013, the Board of Directors adopted an advance notice policy (the "Advance Notice Policy") with immediate effect, a copy of which is set out in Schedule "D" to this Information Circular and Proxy Statement, consistent with developments in market practice whereby advance notice policies have become more prevalent for Canadian and U.S. companies. In order for the Advance Notice Policy to remain in effect following termination of the Meeting, the Advance Notice Policy must be ratified, confirmed and approved at the Meeting, as set forth more fully below. The full text of the Advance Notice Resolution appears in Schedule "C" of this Information Circular and Proxy Statement.


Purpose of the Advance Notice Policy

              The Advance Notice Policy: (i) facilitates orderly and efficient annual general or, where the need arises, special, meetings; (ii) ensures that all Shareholders receive adequate notice of the Director nominations and sufficient information with respect to all nominees; and (iii) allows Shareholders to register an informed vote.

              The purpose of the Advance Notice Policy is to provide Shareholders, Directors and management of the Corporation with direction on the procedure for Shareholder nomination of Directors. The Advance Notice Policy is the framework by which the Corporation seeks to fix a deadline by which holders of record of Common Shares of the Corporation must submit Director nominations to the Corporation prior to any annual or special meeting of Shareholders and sets forth the information that a Shareholder must include in the notice to the Corporation for the notice to be in proper written form.


Effect of the Advance Notice Policy

              Subject only to the BCBCA and the Articles, only persons who are nominated in accordance with the following procedures shall be eligible for election as Directors of the Corporation. Nominations of persons for election to the Board of Directors may be made at any annual meeting of Shareholders, or at any special meeting of Shareholders if one of the purposes for which the special meeting was called was the election of Directors: (a) by or at the direction of the Board of Directors, including pursuant to a notice of meeting; (b) by or at the direction or request of one or more Shareholders pursuant to a proposal made in accordance with the provisions of the BCBCA, or a requisition of the Shareholders made in accordance with the provisions of the BCBCA; or (c) by any person (a "Nominating Shareholder"): (A) who, at the close of business on the date of the giving of the notice provided for below in the Advance Notice Policy and on the record date for notice of such meeting, is entered in the securities register as a holder of one or more shares carrying the right to vote at such meeting or who beneficially owns shares that are entitled to be voted at such meeting; and (B) who complies with the notice procedures set forth below in the Advance Notice Policy.

              In addition to any other applicable requirements, for a nomination to be made by a Nominating Shareholder, the Nominating Shareholder must have given timely notice thereof in proper written form to the Corporate Secretary of the Corporation at the principal executive offices of the Corporation.

              To be timely, a Nominating Shareholder's notice to the Corporate Secretary of the Corporation must be made: (a) in the case of an annual meeting of Shareholders (which may also be an annual and special meeting of Shareholders), not less than 30 nor more than 65 days prior to the date of the annual meeting of Shareholders; provided, however, that in the event that the annual meeting of Shareholders is

37


Table of Contents

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 2012 were Barry E. Welch, our President and Chief Executive Officer; Terrence Ronan, our Executive Vice President — Chief Financial Officer (effective August 20, 2012); Paul H. Rapisarda, our Executive Vice President — Commercial Development; and Lisa Donahue, our interim Chief Financial Officer through August 20, 2012 (prior to Mr. Ronan's appointment).

Corporate Performance — Achievements and Business Highlights

              In 2012, we:

              In 2013, in connection with the review of strategy, business prospects, financial position, operating environment and outlook by management and the Board of Directors, the Corporation focused on its objective of providing shareholders with an attractive total return, with a view to appropriately balance the

41


Table of Contents

income and growth components of total return to enhance long-term value. As a result of this review, the Board of Directors, with management's recommendation, approved a reduction in the annual dividend level as announced on February 28, 2013.

Executive Compensation Objectives

              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 and Mr. Rapisarda.

2012 Say-on-Pay Vote

              At the Corporation's Annual Meeting of Shareholders held on June 22, 2012, 88.01% 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 2012 Information Circular and Proxy Statement were 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. Since that time, the Compensation Committee has adopted a share ownership policy for its named executive officers and added clawback provisions to its executive employment agreements. The Compensation Committee will continue to consider the outcome of the Corporation's annual "say-on-pay" votes when making future compensation decisions for named executive officers.

Elements of Executive Compensation

              The compensation of each named executive officer includes a base salary, cash bonus and eligibility for awards under the long-term incentive plan. All compensation decisions for named executive officers are made by the Compensation Committee of the Board of Directors.

Base salary

              The base salaries for the named executive officers (other than Ms. Donahue) for 2012 were based on a review by the Compensation Committee, considering 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, and considering the approximate doubling of the Corporation's enterprise value and market capitalization through acquisitions in 2011. Lisa Donahue, our interim Chief Financial Officer from June 12, 2011 to August 20, 2012, serves as a Managing Director of AlixPartners, LLP ("AlixPartners"), with whom we entered into an agreement for management services relating to fees for Ms. Donahue's services. Accordingly, Ms. Donahue's compensation was not determined by the Compensation Committee.

              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 $575,000 for 2011 and was increased to $700,000 at the beginning of 2012 based on a review of peer company data as well as his accomplishments in achieving the Corporation's goals and objectives and his critical role in executing the Corporation's strategy. The Compensation Committee analyzed salaries paid to the chief executive officer or president of the following companies in making this determination: Calpine Corporation, AES Corporation, GenOn Energy, Inc., NiSource, Inc., Scana Corporation, NorthWestern Corporation, TransAlta Corporation, Just Energy Group Inc., Northland Power Inc., Dynegy Inc., NRG Energy, Inc. and Fortis Inc.

              Terrence Ronan.    On August 20, 2012, Terrence Ronan became the Corporation's Executive Vice President — Chief Financial Officer and Corporate Secretary with an initial annual base salary of $375,000. Mr. Ronan's salary was determined with reference to peer company data. The Compensation Committee analyzed salaries paid to the chief financial officer of the following companies: Calpine Corporation, AES Corporation, GenOn Energy, Inc., NiSource, Inc., Scana Corporation, NorthWestern Corporation, TransAlta Corporation, Just Energy Group Inc., Northland Power Inc., Dynegy Inc., NRG Energy, Inc. and Fortis Inc.

              Paul H. Rapisarda.    Beginning in 2011, Mr. Rapisarda became the Corporation's Executive Vice President — Commercial Development. Mr. Rapisarda's salary was $310,000 for 2011 and was increased to $425,000 at the beginning of 2012 based on a review of peer company data as well as his accomplishments in achieving the Corporation's goals and objectives and his critical role in executing the Corporation's strategy. The Compensation Committee analyzed salaries paid to the chief operating officer, executive vice president or chief financial officer of the following companies in making this determination: Just Energy Group Inc., Enbridge, Inc., Northland Power Inc., Dynegy Inc., NRG Energy, Inc. and Fortis. Inc.

              None of the named executive officers received an increase in annual base salary for the 2013 calendar year.

Annual cash bonus (non-equity incentive plan compensation)

              In the case of Barry E. Welch, President and Chief Executive Officer and Paul H. Rapisarda, Executive Vice President — Commercial Development, for each of the three years 2009 through 2011, annual cash bonuses were determined in accordance with the terms of their respective employment agreements. The cash bonuses paid to Barry E. Welch and Paul H. Rapisarda in January 2012 were the last ones to be determined under the framework provided in their employment agreements. For performance year 2012 and beyond, the Compensation Committee developed and approved a new methodology to determine the cash bonus payable to Barry E. Welch, Terrence Ronan and Paul H. Rapisarda. Payouts under the new short-term incentive program ("STIP") are included in the column identified as "Non-equity incentive plan compensation" in the Summary Compensation Table. The Compensation Committee set target ranges for each named executive officer's cash bonus 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 these three named executive officers for the year ended December 31, 2012 was evaluated utilizing the following four performance criteria:

 
  Chief
Executive
Officer
  Executive
Vice President-
Chief Financial

    30%     20%     20%  

a. Leadership and strategic planning

                   

b. Hiring, mentoring, development and succession planning

                   

c. Commitment, energy level and creativity

Target ranges for STIP as percentages of base salaries

    75-150%     50-100%     50-100%  

              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, 2012, 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 and proceeds from foreign exchange transactions, less general and administrative costs, less taxes paid, less corporate interest and preferred share costs.

              The Corporation's actual Project Adjusted EBITDA for purposes of the STIP for the year ended December 31, 2012 was $333 million, which was $1 million lower than the Board of Directors' approved budget. Cash Flow from Projects for the year ended December 31, 2012 was $275 million, which was $10 million higher than the high end of the Corporation's guidance. The Committee reviewed these results, as well as the Corporation's achievement against the other strategic and operational goals described in the table above and the individual's achievement against the discretionary goals in determining the actual bonus to be paid to each of the named executive officers in respect of 2012.

              For the annual cash bonuses paid in 2013 based on the 2012 performance year, the named executive officers' awards were determined in the first quarter of 2013 to be as follows:

Name
  2012 Bonus Amount   % of Base Salary   Factors considered

Barry E. Welch

  $ 700,000   100%   •  Contribution to the Corporation's achievement of its overall business goals

            •  Discretionary factors described above, including leadership and strategic planning

Terrence Ronan

  $ 150,000   40%, based upon a bonus of approximately 110% of Mr. Ronan's base salary for 2012, prorated to take into account the date he joined the Corporation   •  Contribution to the Corporation's goals, especially regarding financial and risk management

Paul H. Rapisarda

  $ 395,000   93%   •  Contribution to the Corporation's goals, especially achievement of its growth goals

              Our interim Chief Financial Officer, Lisa Donahue, did not receive an annual bonus from us for the 2011 or 2012 performance years as fees for her services were subject to our agreement with AlixPartners.

Long Term Incentive Plan

              The named executive officers and other employees of the Corporation are eligible to participate in the Corporation's Amended and Restated Long Term Incentive Plan ("LTIP"), as in effect from time to time, as determined by the Board of Directors. 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 upon the achievement of strategic, financial and operational objectives critical to growing the Corporation and increasing its long-term value.

45


Table of Contents

              For the LTIP grants made in 2012, the Board of Directors established 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 were achieved, the executive officers would 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 (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 grant date). Notional shares are meant to track the investment performance of Common Shares, including market prices and distributions. Any notional shares granted to an executive officer in respect of a performance period are credited to a notional share account for each executive officer 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.

              On the applicable vesting date for notional shares held in an executive officer's notional share account with respect to these awards, the Corporation will redeem the 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 an exchange for Common Shares. Notwithstanding the foregoing, the Compensation Committee may redeem 100% of an executive officer'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.

              On February 29, 2012, for the 2011 performance year, Barry E. Welch, President and Chief Executive Officer and Paul H. Rapisarda, Executive Vice President — Commercial Development, received annual grants with a value equal to their 2012 salaries of $700,000 and $425,000, respectively, and, in addition, a discretionary one-time special award of 15,000 and 12,000 notional shares, respectively. Each of these awards will vest as to one third over each of the three years following the year of the award, subject to continued employment of the executive officer.

              On September 19, 2012, as part of the compensation package the Corporation offered to Mr. Ronan upon his appointment as Executive Vice President — Chief Financial Officer of the Corporation, and in order to more closely align Mr. Ronan's interests with those of the Corporation and its Shareholders, Mr. Ronan received a grant of 9,000 notional shares. This award vests as to one third over each of the three years following the year of the award, beginning on February 28, 2013, subject to Mr. Ronan's continued employment.

              In 2012, the Compensation Committee reviewed the LTIP for the Corporation's executive officers and considered changes in light of changes to the scale and complexity of the Corporation as well as input about plans for similar companies, especially those in the United States, which is the relevant market for the Corporation's executive officers. Based on this review, the Compensation Committee approved certain changes to the LTIP beginning in 2012. However, as further detailed below, the Board of Directors subsequently determined not to grant awards in 2013 under the LTIP as revised, but rather to grant discretionary awards of notional shares with an initial award amount of $200,000 and $100,000 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 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.

              Under the LTIP as revised, awards for the 2012 performance year would have been based upon a combined measure of Project Adjusted EBITDA per Common Share (as defined below for purposes of the LTIP), Free Cash Flow (as defined below), Growth Cash Flow (as defined below) and relative TSR. Awards under the revised LTIP would have vested as to one third over each of the three years following the year of the award.

              For 2012, the possible quantum of awards under the revised LTIP ranged from zero to a cap of $2.8 million for the Chief Executive Officer and $1.5 million for each of the Executive Vice President — Chief Financial Officer and Executive Vice President — Commercial Development. For 2012, the midpoint targets for each of the four performance measures were set as follows: (1) Project Adjusted EBITDA per Common Share — $2.98 to $3.03; (2) Free Cash Flow — $140.3 million to $143.1 million; (3) Growth Cash Flow — $18.5 million to $21.7 million; and (4) relative TSR — 56th to 65th percentile. If each of these target ranges were achieved in 2012, the recommended award for our Chief Executive Officer would be $1.5 million and for our Executive Vice President — Chief Financial Officer and our Executive Vice President — Commercial Development would be $750,000.

              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 January 1, 2012, have been 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 or dividends. Growth Cash Flow is defined as the pro forma annualized aggregate cash flow from new projects or companies purchased during the year.

              TSR refers to the change in the total value of a Common Share investment in the Corporation over a given period, taking into account reinvested dividends on the Common Shares during such period. For 2012, 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:

              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.

              In light of the Corporation's performance, the decline in the price of its Common Shares in 2012, discussions relating to potential changes in the dividend policy and other related events, the Compensation Committee determined at its February 20, 2013 meeting to delay its decisions regarding LTIP awards for its executive officers in respect of the 2012 performance year. The Compensation Committee believed it needed additional time to consider the impact that those corporate events should have on grant levels and design, in particular given the importance of the LTIP as a means to align the interests of plan participants with those of the Corporation's Shareholders and to assist in attracting, retaining and motivating key employees. In its meetings held on March 11, April 9, and April 11, 2013, the Compensation Committee deliberated as to the appropriate amount and structure of any awards. In its deliberations, the Compensation Committee considered, in addition to the purpose of the LTIP, the 2012 plan design, the range of awards that could have been made under the plan based on performance of the Corporation and the appropriateness of their terms, as well as the decline in the price of the Corporation's Common Shares following the release of the Corporation's earnings for the fiscal year ended December 31, 2012. It also considered, among other factors, the performance of management in 2012 and its impact on the Corporation's results, which was reflected in the annual cash bonus paid under the STIP. During its deliberations, the Compensation Committee consulted with Hugessen, which provided advice concerning relevant pay practices, alignment of compensation with corporate performance and total shareholder return, and award design considerations.

              On April 11, 2012, the Compensation Committee determined to recommend to the Board of Directors, and the Board of Directors approved, the following discretionary 2013 long-term incentive awards in respect of the 2012 performance year:

The Board of Directors determined, upon the recommendation of the Compensation Committee, to make no 2013 long-term incentive award to Mr. Welch, after taking into account his recommendation that he receive no award.

              The awards made to Mr. Rapisarda and Mr. Ronan were converted into notional shares based on the weighted average Canadian dollar closing price of a Common Share on the Toronto Stock Exchange for the five days immediately preceding the grant date of April 11, 2013. The exchange rate for Canadian dollars into U.S. dollars was determined on the basis of the Bank of Canada closing rate on the day prior to the grant date.

              The Compensation Committee also altered the vesting conditions and timing from the awards that would otherwise have been made under the LTIP. Instead of vesting ratably over three years based solely on continued employment, the Committee determined that vesting would occur at the end of a three year period subject to achievement against performance goals. The vesting of the notional shares will be based on relative TSR against the LTIP peer group disclosed above (as may be adjusted by the Compensation Committee) and Project Adjusted EBITDA per Common Share over the three year performance period of April 1, 2013 to March 31, 2016, each with an equal 50% weighting in accordance with the following target ranges:

100-150% vesting, equal to 100% plus an additional 2% for every 1% increase over 100% of budget (capped at vesting of 150%)

              Vesting is also conditioned on continued employment by the Corporation, subject to the provisions of the executive officers' employment agreements relating to certain terminations of employment and change in control (see below under "Potential Payments Upon Termination or Change in Control"). Vested notional shares will generally be settled following the administrator's certification of the

achievement of the performance metrics following March 31, 2016, but no later than June 15, 2016. One third of the notional shares will be settled in cash and two thirds will be settled in Common Shares. The notional shares, any additional notional shares credited following the payment of dividends by the Corporation and any Common Shares settled or cash payments made are also subject to the clawback provisions of the executive officers' employment agreements.

              As described in the Corporation's Information Circular and Proxy Statement for the year ended December 31, 2010, notional shares were granted to executive officers 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 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, the grants vested on February 28, 2013 an amount equal to 50% of the notional shares initially granted and additional notional shares credited following the payment of dividends by the Corporation and Mr. Welch and Mr. Rapisarda received 18,898 and 9,096 Common Shares and $97,608 and $46,980 in cash, respectively (generally intended to be withheld toward payment of taxes that will be owed due to the vesting).

              On April 11, 2013, in order to more closely align Mr. Ronan's interests with those of the Corporation and its Shareholders and in connection with his engagement as Chief Financial Officer, Mr. Ronan received a grant of 6,000 notional shares. This award was one third vested upon grant and vests as to the remaining two thirds in two equal installments on each of February 28, 2014 and February 28, 2015.

              The grants made in 2013 of notional shares under the LTIP and the vesting and settlement of notional shares for the 2010-2012 performance period will appear in the Summary Compensation Table and Stock Vested Table, respectively, in the Corporation's information circular and proxy statement and annual report for the year ended December 31, 2013.

Employment Agreements

              Effective April 15, 2013, in accordance with the terms of his offer letter, the Corporation entered into an employment agreement with Terrence Ronan. 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 Company may, subject to certain conditions, direct that the Company recover all or a portion of bonus or incentive compensation paid to the executive officer or gains realized by the executive officer with respect to equity-based awards or other incentive payments or cancel all or a portion of the stock-based awards granted to an executive officer that is related to a restatement of, or inaccuracy in, the Company'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.

              Effective July 12, 2011, the Corporation entered into an arrangement with AlixPartners to provide various accounting and financial consulting services. Pursuant to the arrangement, the Corporation announced the appointment of Lisa Donahue of AlixPartners as interim Chief Financial Officer and engaged other consultants from AlixPartners, the services of each of whom were billed by AlixPartners. Ms. Donahue served as interim Chief Financial Officer until the appointment of Terrence Ronan as the Corporation's Executive Vice President — Chief Financial Officer on August 20, 2012.

              Effective April 15, 2013, the Corporation also entered into employment agreement with Edward Hall, its newly appointed Executive Vice President — Chief Operating Officer, on terms similar to those of Mr. Ronan and Mr. Rapisarda described above and under the section of this Information Circular and Proxy Statement titled "Potential Payments Upon Termination or Change in Control."

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 2012 was $17,000 for participants under age 50 and $22,500 for participants 50 and over.

Perquisites

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

Share Ownership Policy

              On April 1, 2013, the Board of Directors 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 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 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 April 1, 2013, when the Policy went into effect, although the grace period is still in effect for Mr. Welch, Mr. Ronan and Mr. Rapisarda, each of Mr. Welch and Mr. Rapisarda met the share ownership requirements.

              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 and Paul H. Rapisarda 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 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 and Mr. Rapisarda), 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; (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 and Mr. Rapisarda) 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 executive a general waiver and release of claims against the Corporation and its affiliates, in a form to be mutually agreed by the Board of Directors and the executive officer.

              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 and

56


Table of Contents

Mr. Rapisarda) 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 and Mr. Rapisarda) 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.

              If Mr. Welch, Mr. Ronan or Mr. Rapisarda 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. Rapisarda or Mr. Ronan 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. Rapisarda or Mr. Ronan 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, 2012, 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, 2012 (and for Mr. Ronan that his employment agreement was in effect as of that date) 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 termination. The actual amounts to be paid out can only be determined at the time of each such executive officer's separation from the Corporation.

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. 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 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

58


Table of Contents

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 will be 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 target 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 an exchange for 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 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

59


Table of Contents

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 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            % of the issued and outstanding Common Shares as of April 26, 2013, 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

60


Table of Contents

under the LTIP upon the redemption of notional shares granted under the LTIP is 276,322, which represents            % of the issued and outstanding Common Shares as of April 26, 2013. The total number of Common Shares that remain issuable under the LTIP is 723,678, which represents            % of the issued and outstanding Common Shares as of April 26, 2013.


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 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 interest 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)

61


Table of Contents

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 April 1, 2013, when the Policy went into effect, all Directors subject to the Policy met the share ownership requirements or were within the Policy's grace period.

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 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, 2012. Directors who are also executive officers of the Corporation are not entitled to any compensation for their services as a Director.

              During 2012, none of the executive officers of the Corporation has served as: (i) a member of the compensation committee (or other committee of the board of directors performing equivalent functions or, in the absence of any such committee, the entire board of directors) of another entity, one of whose executive officers served on the Compensation Committee of the Corporation; (ii) a director of another entity, one of whose executive officers served on the Board of Directors of the Corporation; or (iii) a member of the compensation committee (or other committee of the board of directors performing equivalent functions or, in the absence of any such committee, the entire board of directors) of another entity, one of whose executive officers served on the Board of Directors of the Corporation.


Certain Relationships and Related Transactions

              Effective July 12, 2011, the Corporation entered into an arrangement with AlixPartners to provide various accounting and financial consulting services. Pursuant to the arrangement, the Corporation announced the appointment of Lisa Donahue of AlixPartners as interim Chief Financial Officer and engaged other consultants from AlixPartners, the services of each of whom are billed by AlixPartners. Ms. Donahue is a Managing Director of AlixPartners. We are unable to determine the amount received by Ms. Donahue in connection with her services to us in 2012 and 2011, as we did not compensate Ms. Donahue directly; rather, Ms. Donahue was compensated independently pursuant to separate arrangements between her and AlixPartners. Under our agreement with AlixPartners, we incurred $1,079,241 and $1,065,312 in the aggregate in 2012 and 2011, respectively, including $825,000 and $603,000 for Ms. Donahue's services in 2012 and 2011, respectively.

The Board of Directors will review and preapprove all relationships and transactions in which the Corporation and any of the its Directors, director nominees and executive officers and their immediate family members, as well as holders of more than 5% of any class of its voting securities and their family members, have a direct or indirect material interest. In preapproving or rejecting such proposed relationships and transactions, the Board of Directors shall consider the relevant facts and circumstances available and deemed relevant to this determination. When appropriate, the Board of Directors will review a report of an independent financial advisor in making a decision on whether to preapprove a related party transaction.

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

              While 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".

A-2


Table of Contents

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


Responsibilities of Chair

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


Decisions Requiring Prior Approval of the Board of Directors

              Approval of the Board shall be required for:

A-3


Table of Contents

              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.


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.

              While it is the intent of the Board to follow an agreed meeting schedule as closely as possible, it is felt that, 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:

Table of Contents


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.
