It is expected that solicitation will be primarily by mail, but proxies may also be solicited personally, by telephone or facsimile or other similar means by Suncor employees or agents. Custodians and fiduciaries will be supplied with proxy materials to forward to beneficial owners of common shares of Suncor and normal handling charges will be paid for such forwarding services. The record date to determine which shareholders are entitled to receive notice of and vote at the meeting is March 4, 2013.

Your vote is very important to us. We encourage you to exercise your vote using any of the voting methods described herein. To be valid, completed proxy forms must be dated, completed, signed and deposited with our transfer agent, Computershare Trust Company of Canada ("Computershare"): (i) by mail using the enclosed return envelope or one addressed to Computershare Trust Company of Canada, Proxy Department, 135 West Beaver Creek, P.O. Box 300, Richmond Hill, Ontario, L4B 4R5; (ii) by hand delivery to Computershare, 9th Floor, 100 University Avenue, Toronto, Ontario, M5J 2Y1; or (iii) by facsimile to (416) 263-9524 or 1-866-249-7775.

Please read the following for commonly asked questions and answers regarding voting and proxies.

Q. Am I entitled to vote?

A.  You are entitled to vote if you are a holder of common shares of Suncor as of the close of business on March 4, 2013, the record date for the meeting. Each common share is entitled to one vote. A simple majority of votes (50% plus one vote) cast at the meeting in person or by proxy is required to approve all matters. The list of registered shareholders maintained by Suncor will be available for inspection after March 4, 2013, during usual business hours at the offices of Computershare, 600, 530 - 8^th Avenue SW, Calgary, Alberta T2P 3S8 and will be available at the meeting.

Q. What am I voting on?

•

the appointment of PricewaterhouseCoopers LLP as auditors of the Corporation until the close of the next annual meeting;

•

Q. What if amendments are made to these matters or if other matters are brought before the meeting?

A.  If you attend the meeting in person and are eligible to vote, you may vote on such matters as you choose. If you have completed and returned a proxy, the securities represented by proxy will be voted or withheld from voting in accordance with your instructions on any ballot that may be called for and, if you specify a choice with respect to any matter to be acted upon, the securities will be voted accordingly. The persons named in the proxy form will have discretionary authority with respect to amendments or variations to matters identified in the Notice of Annual General Meeting and to other matters that may properly come before the meeting. As of the date of this management proxy circular, our management knows of no such amendment, variation or other matter expected to come before the meeting. If any other matters properly come before the meeting, the persons named in the proxy form will vote on them in accordance with their best judgment.

Q. Who is soliciting my proxy?

A.  The management of Suncor is soliciting your proxy. Solicitation of proxies is done primarily by mail, supplemented by telephone or other contact, by our employees or agents at a nominal cost, and all of these costs are paid by Suncor.

2        SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

Q. How can I vote?

A.  If you are eligible to vote and your shares are registered in your name, you can vote your shares in person at the meeting or by completing your proxy form through any of the methods described above.

If your shares are not registered in your name but are held by a nominee, please see below.

Q. How can a non-registered shareholder vote?

A.  If your shares are not registered in your name, but are held in the name of a nominee (usually a bank, trust company, securities broker or other financial institution), your nominee is required to seek your instructions as to how to vote your shares. Your nominee will have provided you with a package of information, including these meeting materials and either a proxy or a voting form. Carefully follow the instructions accompanying the proxy or voting form.

Q. How can a non-registered shareholder vote in person at the meeting?

A.  Suncor does not have access to all the names of its non-registered shareholders. Therefore, if you are a non-registered shareholder and attend the meeting, we will have no record of your shareholdings or of your entitlement to vote unless your nominee has appointed you as a proxyholder. If you wish to vote in person at the meeting, insert your name in the space provided on the proxy form or voting form sent to you by your nominee. In doing so you are instructing your nominee to appoint you as a proxyholder. Complete the form by following the return instructions provided by your nominee. You should report to a representative of Computershare upon arrival at the meeting.

Q. Who votes my shares and how will they be voted if I return a proxy?

A.  By properly completing and returning a proxy, you are authorizing the person named in the proxy to attend the meeting and vote your shares. You can use the enclosed proxy form, or any other proper form of proxy, to appoint your proxyholder.

The shares represented by your proxy must be voted according to your instructions in the proxy. If you properly complete and return your proxy but do not specify how you wish the votes cast, your shares will be voted as your proxyholder sees fit. Unless contrary instructions are provided, shares represented by proxies received by management will be voted:

•

FOR the election of directors from those nominees set out in this management proxy circular;

•

FOR the appointment of PricewaterhouseCoopers LLP as auditors;

•

FOR the amendment to the SOP to increase the number of common shares reserved thereunder by 23,000,000 common shares; and

•

FOR the approach to executive compensation disclosed in this management proxy circular.

Q. Can I appoint someone other than the individuals named in the enclosed proxy form to vote my shares?

A.  Yes, if you are a registered holder, you have the right to appoint the person or company of your choice, who does not need to be a shareholder, to attend and act on your behalf at the meeting. If you wish to appoint a person other than the names that appear, then strike out those printed names appearing on the proxy form and insert the name of your chosen proxyholder in the space provided.

NOTE: It is important to ensure that any other person you appoint is attending the meeting and is aware that his or her appointment to vote your shares has been made. Proxyholders should, upon arrival at the meeting, present themselves to a representative of Computershare.

Q. What if my shares are registered in more than one name or in the name of my company?

A.  If the shares are registered in more than one name, all those registered must sign the form of proxy. If the shares are registered in the name of your company or any name other than yours, you may be required to provide documentation that proves you are authorized to sign the proxy form.

Q. Can I revoke a proxy or voting instruction?

A.  If you are a registered shareholder and have returned a proxy, you may revoke it by:

1.

completing and signing a proxy bearing a later date, and delivering it to Computershare; or

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR        3

2.

delivering a written statement, signed by you or your authorized attorney to:

the Corporate Secretary of Suncor Energy Inc. at P.O. Box 2844, 150 - 6^th Avenue S.W., Calgary, Alberta, T2P 3E3 at any time up to and including the last business day prior to the meeting, or the business day preceding the day to which the meeting is adjourned; or

(b)

to the Chairman of the meeting prior to the start of the meeting.

If you are a non-registered shareholder, contact your nominee.

Q. Is my vote confidential?

A.  Your proxy vote is confidential. Proxies are received, counted and tabulated by our transfer agent, Computershare. Computershare does not disclose the results of individual shareholder votes unless: they contain a written comment clearly intended for management; in the event of a proxy contest or proxy validation issue; or if necessary to meet legal requirements.

Q. How many common shares are outstanding?

A.  As of February 22, 2013, there were 1,523,644,237 common shares outstanding. We have no other class or series of voting shares outstanding.

As of February 22, 2013, there was no person who, to the knowledge of our directors and officers, beneficially owned, or controlled or directed, directly or indirectly, common shares carrying more than 10% of the voting rights attached to all outstanding common shares.

Q. What is electronic delivery?

A.  Electronic delivery is voluntary e-mail notification sent to shareholders when documents such as our annual report, quarterly reports and this management proxy circular are available on our web site. If you wish, you may elect to be notified by e-mail when documentation is posted on our web site. Electronic delivery will save paper, reduce our impact on the environment and reduce costs.

Q. How can I ask for electronic delivery?

ADVISORIES

This management proxy circular and the schedules hereto contain certain forward-looking information and forward-looking statements (collectively referred to herein as "forward-looking statements") within the meaning of applicable Canadian and U.S. securities laws. Forward-looking statements and other information are based on Suncor's current expectations, estimates, projections and assumptions that were made by the company in light of information available at the time the statement was made and consider Suncor's experience and its perception of historical trends, including: expectations and assumptions concerning the accuracy of reserves and resources estimates; commodity prices and interest and foreign exchange rates; capital efficiencies and cost-savings; applicable royalty rates and tax laws; future production rates; the sufficiency of budgeted capital expenditures in carrying out planned activities; the availability and cost of labour and services; and the receipt, in a timely manner, of regulatory and third-party approvals. In addition, all other statements and other information that address expectations or projections about the future, and other statements and information about Suncor's strategy for growth, expected and future expenditures or investment decisions, commodity prices, costs, schedules, production volumes, operating and financial results, future financing and capital activities, and the expected impact of future commitments are forward-looking statements. Some of the forward-looking statements and information may be identified by words like "expect", "guidance", "anticipated", "estimated", "plans", "scheduled", "belief", "projects", "could", "target", "will", "should", "may", "focus", "vision", "goal", "intend", "indicate", "objective", "continue" and similar expressions. Forward-looking statements in this management proxy circular and the schedules hereto include references to the following: the business of and procedure for the annual general meeting; management's expectation that none of the nominees for director will be unable to serve as director; Suncor's indication that no future stock option grants are planned for non-employee directors; expectations regarding development of the Claw Back Policy (as defined herein) in the future; expectations that the President and CEO's compensation opportunity will increase over time; the belief that improving year over year operational results will ultimately deliver shareholder value; that values ultimately received could be quite different from realizable pay depending on future performance; estimates of compensation paid or to be paid by our peers; the belief that Suncor's multi-year compensation plan balances risk and reward; Suncor's conclusions with respect to the key risk mitigation features of Suncor's compensation policies and programs and Suncor's belief that it would be difficult for anyone in management acting alone, or acting as a group, to make "self-interested" decisions for immediate short-term gains that could have a material impact on the organization's financial or share price performance; Suncor's belief that executives' interests should be aligned with the interests of Suncor's shareholders; Suncor's belief that it continues to be well-positioned to capitalize on business opportunities; the Corporation's intentions with respect to the investment of capital in growth projects and delivering profitable growth; the Board's belief that Suncor's leadership succession and transition plan has been soundly executed; the Board's belief that the company's financial strategy is appropriate and is being effectively stewarded; that the growth project evaluation work that was undertaken in 2012 has helped to better position the company for improvement in ROCE (as defined herein) metrics; the expectation that Firebag Stage 4 will be 15% under the announced cost of $2 billion; that TRO_TM, the company's tailings management system, is expected to significantly accelerate the pace of tailings reclamation; that mid- and long-term incentive amounts shown for Named Executive Officers (as defined herein) will differ from the ultimate value realized from the awards based on Suncor's relative and absolute share price performance over time; that the HR&CC (as defined herein) will continue the practice of doing a look back analysis of the CEO's compensation; changes to the compensation valuation methodology used by Suncor to value LTI (as defined herein) awards and disclosure of the same; changes to the methodology used for disclosing the value of share-based and option-based awards; estimates as to annual pensions that would be received by Named Executive Officers following retirement; changes to PSU (as defined herein) vesting design and the PSU peer group; the composition of the Board of Directors following the annual general meeting; Suncor's corporate governance practices and those of the Board of Directors; and expectations for Suncor's Board members in carrying out their duties as directors.

Forward-looking statements and information are not guarantees of future performance and involve a number of risks and uncertainties, some that are similar to other oil and gas companies and some that are unique to Suncor. Suncor's actual results may differ materially from those expressed or implied by its forward-looking statements, so readers are cautioned not to place undue reliance on them.

Risks, uncertainties and other factors that could influence the financial and operating performance of all of Suncor's operating segments and activities include, but are not limited to, changes in general economic, market and business conditions, such as commodity prices, interest rates and currency exchange rates; fluctuations in supply and demand for Suncor's products; the successful and timely implementation of capital projects, including growth projects and regulatory projects; competitive actions of other companies, including increased competition from other oil and gas companies or from companies that provide alternative sources of energy; labour and material shortages; actions by government authorities, including the imposition or reassessment of taxes or changes to fees and royalties, and changes in environmental and other regulations; the ability and willingness of parties with whom we have material relationships to perform their obligations to us; the occurrence of unexpected events such as fires, equipment failures and other similar events affecting Suncor or other parties whose operations or assets directly or indirectly affect Suncor; the potential for security breaches of Suncor's information systems by computer hackers or cyberterrorists, and the unavailability or failure of such systems to perform as anticipated as a result of such

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR        5

breaches; our ability to find new oil and gas reserves that can be developed economically; the accuracy of Suncor's reserves, resources and future production estimates; market instability affecting Suncor's ability to borrow in the capital debt markets at acceptable rates; maintaining an optimal debt to cash flow ratio; the success of the company's risk management activities using derivatives and other financial instruments; the cost of compliance with current and future environmental laws; risks and uncertainties associated with closing a transaction for the purchase or sale of an oil and gas property, including estimates of the final consideration to be paid or received, the ability of counterparties to comply with their obligations in a timely manner and the receipt of any required regulatory or other third-party approvals outside of Suncor's control that are customary to transactions of this nature; and the accuracy of cost estimates, some of which are provided at the conceptual or other preliminary stage of projects and prior to commencement or conception of the detailed engineering that is needed to reduce the margin of error and increase the level of accuracy. The foregoing important factors are not exhaustive.

Suncor's Annual Information Form for the year ended December 31, 2012, Suncor's Management's Discussion and Analysis for the year ended December 31, 2012 (the "MD&A") and other documents it files from time to time with securities regulatory authorities describe the risks, uncertainties, material assumptions and other factors that could influence actual results and readers are referred to such documents. Copies of these documents and Suncor's audited consolidated financial statements for the year ended December 31, 2012 are available without charge from Suncor at 150 - 6^th Avenue S.W., Calgary, Alberta T2P 3E3, by calling 1-800-558-9071, or by email request to info@suncor.com or by referring to the company's profile on SEDAR at www.sedar.com or EDGAR at www.sec.gov. Except as required by applicable securities laws, Suncor disclaims any intention or obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Financial information is reported in Canadian dollars, unless otherwise noted, and is provided in Suncor's audited consolidated financial statements for the year ended December 31, 2012 and the MD&A, which are included in our 2012 Annual Report.

Certain financial measures in this management proxy circular – namely operating earnings, cash flow from operations ("CFOPS"), Oil Sands cash operating costs and return on capital employed ("ROCE") – are not prescribed by Canadian generally accepted accounting principles ("GAAP"). Operating earnings and Oil Sands cash operating costs are defined in the Non-GAAP Financial Measures Advisory section of the MD&A and reconciled to GAAP measures in the Consolidated Financial Information and Segment Results and Analysis sections of the MD&A. CFOPS and ROCE are defined and reconciled to GAAP measures in the Non-GAAP Financial Measures Advisory section of the MD&A. CFOPS, for the purposes of the table on page 37 of this management proxy circular, has been further adjusted to take into account adjustments for Syria and Libya. ROCE, for the purposes of the table on page 37 of this management proxy circular, has been further adjusted to exclude the impact of the impairment charge against the Voyageur upgrader project and impairment charges pertaining to assets in Syria and Libya. These non-GAAP financial measures are included because management uses the information to analyze operating performance, leverage and liquidity. These non-GAAP financial measures do not have any standardized meaning and, therefore, are unlikely to be comparable to similar measures presented by other companies and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP.

Suncor converts certain natural gas volumes to thousands of barrels of oil equivalent per day ("mboe/d") on the basis of one barrel ("bbl") for every six thousand cubic feet ("mcf") of natural gas. Any figure presented in mboe/d may be misleading, particularly if used in isolation. A conversion ratio of six mcf of natural gas to one bbl of crude oil is based on an energy equivalency conversion method primarily applicable at the burner tip and does not necessarily represent a value equivalency at the wellhead. Given that the value ratio based on the current price of crude oil as compared to natural gas is significantly different from the energy equivalency of 6:1, conversion on a 6:1 basis may be misleading as an indication of value.

BUSINESS OF THE MEETING

FINANCIAL STATEMENTS

The audited consolidated financial statements for the year ended December 31, 2012 and the report of the auditors thereon will be placed before the meeting. These audited consolidated financial statements form part of our 2012 Annual Report. Copies of the 2012 Annual Report may be obtained from the Corporate Secretary upon request and will be available at the meeting. The full text of the 2012 Annual Report is available on Suncor's web site at www.suncor.com and has been filed with the Canadian securities regulatory authorities and the U.S. Securities and Exchange Commission.

ELECTION OF DIRECTORS

Number of Directors. Suncor's articles stipulate there shall be not more than 15 nor fewer than 8 directors. There are currently 12 directors. In accordance with our by-laws, the Board of Directors of Suncor (the "Board" or "Board of Directors") has determined that 12 directors will be elected at the meeting. The term of office of each director is from the date of the meeting at which he or she is elected or appointed until the next annual meeting of shareholders or until a successor is elected or appointed.

Unless authority to do so is withheld, the persons named in the accompanying form of proxy intend to vote FOR the election of the nominees whose names appear on pages 8 to 13. Management does not expect that any of the nominees will be unable to serve as a director but, if that should occur for any reason prior to the meeting, the persons named in the accompanying form of proxy reserve the right to vote for another nominee at their discretion unless the proxy specifies the common shares are to be withheld from voting in the election of directors.

Majority Voting for Directors. The Board has adopted a policy that requires that any nominee for director who receives a greater number of votes "withheld" than votes "for" his or her election as a director shall submit his or her resignation to the Governance Committee of the Board for consideration promptly following the meeting. This policy applies only to uncontested elections, meaning elections where the number of nominees for directors is equal to the number of directors to be elected. The Governance Committee shall consider the resignation and shall provide a recommendation to the Board. The Board will consider the recommendation of the Governance Committee and determine whether to accept it within 90 days of the applicable meeting and a news release will be issued by Suncor announcing the Board's determination. A director who tenders his or her resignation will not participate in any meetings to consider whether the resignation shall be accepted.

Shareholders should note that, as a result of the majority voting policy, a "withhold" vote is effectively the same as a vote against a director nominee in an uncontested election.

APPOINTMENT OF AUDITORS

Management and the Board propose that PricewaterhouseCoopers LLP be appointed as Suncor's auditors until the close of the next annual meeting. PricewaterhouseCoopers LLP have been Suncor's auditors for more than five years.

Fees payable to PricewaterhouseCoopers LLP in 2011 and 2012 are detailed below.

($ thousands)	2011	2012
Audit Fees	6 145	5 904
Audit-Related Fees	423	429
Tax Fees	50	50
All Other Fees	9	125
Total	6 627	6 508

The nature of each category of fees is described below.

Audit Fees. Audit Fees were paid for professional services rendered by the auditors for the audit of Suncor's annual financial statements, or services provided in connection with statutory and regulatory filings or engagements.

Audit-Related Fees. Audit-Related Fees were paid for professional services rendered by the auditors for the review of quarterly financial statements and for the preparation of reports on specified procedures as they relate to audits of joint arrangements and attest services not required by statute or regulation.

Tax Fees. Tax Fees for corporate tax filings and tax planning were paid in a foreign jurisdiction where Suncor has limited activity.

All Other Fees. All Other Fees were subscriptions to auditor-provided and supported tools.

All services described beside the captions "Audit Fees", "Audit-Related Fees", "Tax Fees" and "All Other Fees" were approved by the Audit Committee in compliance with paragraph (c)(7)(i) of Rule 2-01 of Regulation S-X under the U.S. Securities and Exchange Act of 1934, as amended (the "Exchange Act"). None of the fees described above were approved by the Audit Committee pursuant to paragraph (c)(7)(i)(C) of Regulation S-X under the Exchange Act.

INCREASE IN COMMON SHARES RESERVED FOR ISSUANCE UNDER SUNCOR ENERGY INC. STOCK OPTION PLAN

As part of the merger with Petro-Canada, effective August 1, 2009, Suncor adopted the SOP, which provides for the grant of options to purchase Suncor common shares, as well as the grant of Stock Appreciation Rights ("SARs"). For further details relating to the SOP, see "Summary of Incentive Plans – Suncor Energy Stock Option Plan".

The purpose of the SOP is to align the interests of the officers, employees and, if designated by the Board, certain other persons providing services on an ongoing basis to Suncor and its subsidiaries with the profitability, growth and future success of Suncor by providing eligible plan participants with the opportunity to acquire an ownership interest in Suncor. The Board believes that the granting of options is an important part of Suncor's overall compensation program. As a long-term incentive, it also serves to ensure Suncor delivers market competitive compensation to plan participants and supports attracting and retaining talented employees in a competitive employment market.

When it was established, a maximum of 45,845,554 common shares were reserved for issuance under the SOP comprising common shares reserved for issuance under the pre-merger Suncor Energy Stock Option Plan and the pre-merger Petro-Canada Employee Stock Option Plan (the "PCSOP"). The Board of Directors has approved, subject to shareholder approval, an amendment to increase the total number of common shares reserved for issuance under the SOP by 23,000,000.

The purpose of the additional reservation is to ensure that a sufficient number of common shares remain reserved for issuance under the SOP to enable the Corporation to continue its current practice of granting options to eligible plan participants as a component of Suncor's long-term incentive program. The long-term incentive program, consisting of options and performance share units at the executive level and options and restricted share units at the senior manager level, aligns eligible participants' interests with shareholders by rewarding them for increases in Suncor's share price and for shareholder returns that exceed those of our peers.

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR        15

Shareholders are being requested to approve an increase in the number of common shares reserved for issuance under the SOP by 23,000,000. The following table sets forth the number of common shares which may be subject to awards granted under the SOP, both before and after the proposed amendment, as of February 22, 2013.

	Common Shares Subject to Outstanding Awards	Common Shares Available for Future Award Grants	Maximum Common Shares Subject to and Available for Award Grants
Currently Approved	28 793 457	2 992 682	31 786 139
Proposed Increase	N/A	23 000 000	23 000 000
Total	28 793 457	25 992 682	54 786 139
Percentage of Outstanding Common Shares	1.9%	1.7%	3.6%

This additional reservation has been conditionally approved by the TSX and must be approved by a majority of votes cast by shareholders at the meeting. Accordingly, at the meeting, shareholders will be asked to consider and, if deemed fit, to approve, by a simple majority of votes cast at the meeting, the following resolution:

"Resolved as an ordinary resolution of Suncor Energy Inc. (the "Corporation") that:

1.

The number of common shares of the Corporation reserved for issuance pursuant to the Suncor Energy Inc. Stock Option Plan is increased by an additional 23,000,000 common shares; and

2.

Any officer or director of the Corporation be and is hereby authorized for and on behalf of the Corporation, under corporate seal or otherwise, to do all such things and to execute all such documents or instruments as may be necessary or desirable to give effect to this resolution."

ADVISORY VOTE ON APPROACH TO EXECUTIVE COMPENSATION

The Board believes that shareholders should have the opportunity to fully understand the objectives, philosophy and principles that the Board has used to make executive compensation decisions.

We hope you will carefully review the "Letter to Shareholders" beginning on page 22 and our "Compensation Discussion and Analysis" beginning on page 25 of this management proxy circular before voting on this matter. We encourage any shareholder who has comments on our approach to executive compensation to forward these comments to the chair of the Human Resources and Compensation Committee (the "HR&CC") c/o the Corporate Secretary, Suncor Energy Inc. P.O. Box 2844, 150 - 6 ^th Avenue S.W., Calgary, Alberta, T2P 3E3. The "Compensation Discussion and Analysis" section discusses our compensation philosophy and approach to executive compensation, what our named executive officers are paid and how their level of compensation is determined. This disclosure has been approved by the Board on the recommendation of the HR&CC.

At the meeting, shareholders will have an opportunity to vote on our approach to executive compensation through consideration of the following advisory resolution:

"Resolved, on an advisory basis and not to diminish the role and responsibilities of the Board of Directors, that the shareholders accept the approach to executive compensation disclosed in the management proxy circular of Suncor Energy Inc. delivered in advance of its 2013 annual meeting of shareholders."

As this is an advisory vote, the results will not be binding upon the Board. However, in considering its approach to compensation in the future, the Board will take into account the results of the vote, together with feedback received from shareholders in the course of our engagement activities.

BOARD OF DIRECTORS COMPENSATION

The Board is composed of 11 non-employee directors, including the chairman of the Board, and Steven W. Williams, our President and Chief Executive Officer ("CEO"). Following the annual general meeting, and assuming that all directors are elected as contemplated in this management proxy circular, the Board will be composed of 11 non-employee directors and Steven W. Williams.

COMPENSATION PHILOSOPHY AND APPROACH

The compensation of non-employee directors is intended to attract highly qualified individuals with the capability to meet the demanding responsibilities of Board members and to closely align non-employee directors' interests with shareholder interests. Non-employee director compensation is not incentive based. Steven W. Williams does not receive additional compensation for Board service.

The Governance Committee reviews Board compensation levels annually to ensure Suncor's approach to Board compensation is competitive at the median of the Suncor Compensation Peers, as such term is defined on page 33 of this management proxy circular, reflects best practice and takes into account governance trends.

Total compensation for non-employee directors consists of annual retainers, meeting fees and an annual equity award provided in the form of DSUs. The Governance Committee engages Towers Watson to benchmark non-employee director and Board chairman compensation, provide information and advice on director and Board chairman compensation governance and best practice trends. This information is used by the Governance Committee in determining the non-employee director and Board chairman compensation recommended annually to the full Board for approval.

COMPENSATION STRUCTURE

The North American energy peers, defined as the Suncor Compensation Peers, for benchmarking director compensation are the same companies used for benchmarking senior executive compensation for Suncor, as provided for on page 33 of this management proxy circular. Where Suncor ranks, as compared to the Suncor Compensation Peers, in relation to revenues, market capitalization and assets, is also provided for on page 33 of this management proxy circular.

The compensation structure for the Board's members did not change from 2011 to 2012. The following table displays the compensation structure for 2012 for all non-employee directors, including the chairman of the Board.

The number of DSUs to be awarded in 2012 was set by the Board at the beginning of 2012 based on target values for non-employee directors (other than the chairman of the Board) of $180,000 (which equalled 5,900 DSUs) and the chairman of the Board of $280,000 (which equalled 9,100 DSUs). DSUs are administered quarterly.

(5)

No other compensation was payable to the chairman of the Board for 2012.

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR        17

"As at February 22, 2013,
all non-employee directors, including the chairman of
the Board, met their share ownership guidelines."
Share Ownership Guidelines. One way non-employee directors demonstrate their commitment to Suncor's long-term success and alignment with shareholders is through share ownership. The Board has established share ownership guidelines for non-employee directors, which must be attained within five years of when they were first elected or appointed.

For 2012, each non-employee director was required to own Suncor common shares and DSUs with a market value of $540,000, and the chairman of the Board was required to own Suncor common shares and DSUs with a market value of $1,400,000. In the case of Mr. Haseldonckx, the RSUs granted to him under the PCRSU Plan are also counted towards this requirement. As at February 22, 2013, all non-employee directors, including the chairman of the Board, met their share ownership guidelines.

Share ownership guidelines are reviewed periodically based on survey data. The current share ownership guideline level was determined to be appropriate for 2013.

Committee Membership. The following table sets forth the current committee members, all of whom are non-employee directors.

EQUITY BASED COMPENSATION

"DSUs are an important component of non-employee director compensation as they provide a stake in Suncor and promote greater alignment between directors
and shareholders."
Annual DSU Grant. Non-employee directors participate in the Suncor Deferred Share Unit Plan (previously defined as the "DSU Plan"). When redeemed, each DSU pays the holder the then-current cash equivalent of the market price per share, as calculated in accordance with the DSU Plan. DSUs are an important component of non-employee director compensation as they provide a stake in Suncor and promote greater alignment between directors and shareholders.

Under the DSU Plan, each non-employee director receives an annual DSU grant as part of his or her total compensation. The annual grant of DSUs is awarded in equal quarterly instalments. In 2012, non-employee directors, including the chairman of the Board, received an aggregate of 69,575 DSUs. Each non-employee director, other than the chairman, received 5,900 DSUs. The chairman of the Board received 9,100 DSUs.

For each new non-employee director, the DSU Plan provides for an additional grant equal to the annual grant for the year in which he or she is appointed to the Board. New non-employee directors, including a new chairman of the Board, who join after February of a calendar year, will receive a pro-rated annual DSU grant based on the date they join the Board.

Fees Paid in DSUs. Until the share ownership guidelines for non-employee directors are met (see page 18 of this management proxy circular for details), non-employee directors receive one-half or, if they choose, all of their fees (excluding expense reimbursements) in the form of DSUs. The number of DSUs to be credited to the non-employee director's account on each payment date is equal to the number of common shares that could have been purchased on the quarterly payment date based on the fees allocated to the director. On each dividend payment date for common shares, an additional number of DSUs, equivalent to the number of common shares that could have been acquired on that date by notional dividend reinvestment, are credited to the non-employee directors' DSU accounts.

Redemption of DSUs. DSUs will be redeemed when a non-employee director ceases to hold office, or on a date elected by that director prior to November 30 of the following calendar year. For directors subject to payment of U.S. federal tax, the redemption period to elect payout of the DSUs they hold commences on the first day of the calendar year following that year in which the non-employee director ceases to be a member of the Board, and ends on November 30 of that same year. However, no redemption will be permitted within the first six months following separation from service by a U.S. taxpayer who is considered a "specified employee". The cash payment at redemption is calculated by multiplying the number of DSUs by the then-current market value of a common share.

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR        19

Stock Options. In accordance with best practice guidelines, stock option grants to non-employee directors were discontinued after 2008. All stock options that were granted to directors through 2008 vested prior to January 1, 2012. No future stock option grants to non-employee directors are planned.

Director Equity Compensation Hedging. Pursuant to Suncor's policies, directors are not permitted to engage in short selling in Suncor common shares or purchase financial instruments (including, for greater certainty, puts, options, calls, prepaid variable forward contracts, equity swaps, collars or units of exchange funds) that are designed to hedge or offset a change in the market value of common shares or other securities of Suncor held by the director.

EXECUTIVE COMPENSATION

LETTER TO SHAREHOLDERS

To Our Fellow Shareholders:

As the Chair of the Human Resources and Compensation Committee ("HR&CC") and Chairman of the Board of Directors (the "Board") of Suncor Energy Inc. ("Suncor"), we would like to take this opportunity to communicate with you about how we manage executive compensation at Suncor, and how our programs align with performance and Suncor's strategic direction.

Your Board is committed to delivering long-term shareholder value. This commitment is reflected in our structure as an integrated energy company, which takes advantage of an excellent resource position, complementary upstream and downstream assets, reliable operations and an excellent suite of growth projects to grow future value for shareholders.

Effective December 1, 2011, Mr. Steve Williams became our President and effective May 1, 2012, he was appointed Chief Executive Officer ("CEO") by the Board, following a robust succession plan. Mr. Williams' previous roles included Chief Operating Officer, Executive Vice President – Oil Sands and Chief Financial Officer.

Suncor's Market for Senior Executives

Suncor is a substantial company with global operations and multiple business units. We are the largest integrated energy company in Canada, by market capitalization, and the fourth largest in North America. The size and scope of Suncor requires us to attract and retain top executive talent. We compete for this talent with comparable energy companies across North America. To this end, we look to a group of similarly sized Canadian and U.S. energy companies when we assess competitive pay levels for our senior executive team. We also measure ourselves against a similar group of energy companies to benchmark relative shareholder returns under our performance share unit ("PSU") plan. Consistent with our pay philosophy, Suncor's performance directly impacts the ultimate pay realized by our senior executives.

Responsible Management of Executive Compensation: Key Changes in 2012

Suncor has an enduring pay-for-performance philosophy that underpins the design of our programs and is directly reflected in the proportion of at risk mid- and long-term incentives provided to our executives in total direct compensation. In 2012, we made some important changes to our compensation programs.

Since we are a capital intensive business, it is vitally important that we efficiently manage our assets. In 2012, we added return on capital employed to our annual incentive plan as a corporate measure, in addition to our existing cash flow from operations measure.

We provide 50% of our long-term incentive award in PSUs and 50% in stock options to our executives. This performance-oriented structure strongly ties executives' incentives to Suncor's results and returns to our shareholders, as our executives only have the opportunity to realize value when our shareholders do as well.

In 2013, we refined the design of our PSU program for grants beginning in 2013 to ensure that the current peer group continues to contain comparable organizations and to simplify the way we measure performance. Relative performance remains the focus of our PSU program – payouts continue to range from 0% to 200% of target and there is a minimum company rank threshold that must be achieved based on relative shareholder return performance for any of the PSUs to vest.

From a governance perspective, we implemented a claw back policy that is consistent with the types of claw back policies that have been adopted by certain other large Canadian issuers. We continue to monitor market, legal and regulatory practices in this area and anticipate further development of the policy in the future.

Supporting Strong Performance

Suncor's senior executive compensation program is designed to support and reinforce: safe, reliable operations; environmentally and socially responsible practices; profitable growth; and the attraction and retention of skilled employees.

In 2012, Suncor demonstrated strong performance in some key operational excellence areas and in shareholder return. The charts below display Suncor's continued improvement in an important safety measure, Recordable Injury Frequency, compared to Canadian Association of Petroleum Producers ("CAPP") industry data; and Suncor's 2012 total shareholder return ("TSR") compared to our peer group used for benchmarking senior executive compensation and to two market indices.

Our continued focus on operational excellence and profitable growth resulted in a 13% TSR in 2012, including an 18% increase in our dividend in the second quarter of 2012. Our 2012 TSR was better than over 75 percent of our peer group used for benchmarking compensation.

2012 President and CEO Pay Outcomes

Consistent with our protocol for promotions, we increased Mr. Williams' salary and incentive opportunity with his appointment as CEO. In 2012, his total direct compensation (which includes actual salary + actual bonus + annual mid- to long-term incentive awards) was $10.2 million, which was approximately 90% of Suncor's 2012 total direct compensation structure for the President and CEO (the structure is targeted at the median of our North American energy company peer group). We expect his compensation opportunity will increase over time with demonstrated experience and continued results in his role. In addition, his actual pay in any year will vary above or below target depending on company and individual performance.

Close to 90% of the President and CEO's 2012 total direct compensation varied with performance and almost 70% was provided in the form of mid- to long-term incentives, tying a substantial portion of the President and CEO's compensation to shareholder value.

Long Term Pay and Performance Alignment

Over the period of 2008 to 2012, aggregate realizable total direct compensation of our Named Executive Officers ("NEOs") was approximately 21% lower than the value reported in the summary compensation table over the same period. For example, one of the three annual PSU awards with a three year performance period granted within the 2008 to 2012 time-frame did not generate a payout due to underperformance relative to our peer group. As well, the majority of outstanding stock options granted over this period held by the NEOs have yet to deliver value.

While the NEOs have realized increasing short-term incentive compensation from improving operational performance, the aggregate realizable value of annual mid- to long-term incentive compensation is 33% below the expected value for the 2008 to 2012 period. The realizable value of the annual mid- and long-term incentive compensation is in line with Suncor's share price performance over this period and demonstrates Suncor's pay-for-performance philosophy and alignment with shareholder interests.

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR        23

Closing

Your Board, with the support of the HR&CC, is committed to ensuring that Suncor's senior executive compensation is aligned with shareholder interests and enables Suncor's long-term competitiveness. We firmly believe the improving year over year operational results will ultimately deliver shareholder value.

The compensation structure in place for Suncor's senior executives fits our industry, and is appropriately linked to our strategy to build long-term shareholder value. We have always welcomed shareholder feedback on Suncor's business operations, policies and practices, including executive compensation, and we welcome your feedback.

Sincerely,

James Simpson Chair of the Human Resources & Compensation Committee	John Ferguson Chairman of the Board

PAY AND PERFORMANCE AT SUNCOR – HIGHLIGHTS

Suncor's executive compensation programs are designed to reward executives for delivering results and building sustainable shareholder value. Our programs align the interests of our executives with shareholders by tying pay outcomes to our short-, medium-, and long-term performance. Our business is linked to the commodity cycle with significant and long-term capital needs, and requires focus on profitable growth that is achieved through reliable operations conducted in a safe and environmentally and socially responsible way.

The following information is intended to provide a quick reference to some key points regarding pay and performance at Suncor.

Our Size and Scope

Our senior executives are responsible for managing a large, global enterprise with multiple operating units and significant capital expenditures. Suncor is the largest energy company in Canada, by market capitalization, and the fourth largest in North America. Our capital expenditures of over $6 billion per year are larger than the size of most Canadian companies. Because of scale and complexity, our market for skilled executives needs to consider organizations outside of Canada and therefore we look to a broad North American group of energy companies, which comprise the Suncor Compensation Peers (as defined on page 33 of this management proxy circular).

Although we are larger than most of our peers, we target pay at the median of the group and measure performance relative to a similar group of North American energy companies. The table to the right provides Suncor's ranking as compared to the Suncor Compensation Peers, in terms of revenues, assets and market capitalization.


(1)  Percentile rank for Revenues is based on results reported for the nine months ended September 30, 2012 and for Assets is based on results reported as of September 30, 2012. Where applicable, results are converted to Canadian dollars based on the exchange rate on September 30, 2012.


(2)  Percentile rank for Market Capitalization is based on results reported as of December 31, 2012. Where applicable, values are converted to Canadian dollars based on the exchange rate on December 31, 2012.

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR        25

How We Look at Performance

We look at performance from a number of perspectives with the intention of aligning short-term financial and operational metrics with long-term shareholder value creation:

Financial Results	Operational Excellence	Leadership	Shareholder Value
Cash flow from operations Return on capital employed	Safety Environment Reliability People	Individual performance, which includes the successful execution of operational and capital plans	Relative total shareholder return ("TSR") in our performance share units ("PSUs") Absolute share price appreciation through stock options

How Total Direct Compensation is Delivered

Our mix of total direct compensation programs is designed to provide competitive pay and align our executives with performance objectives over short-, medium-, and long-term time periods.

Component	Performance Orientation	Time Frame
Salary (14-30% of compensation)	Reflects the market value of the position as benchmarked against the Suncor Compensation Peers Salary increases reflect performance demonstrated in the job	Reviewed periodically Annual reviews and adjustments
Annual Incentive (17-18% of compensation)	Aligned with financial and operational performance objectives Reflects corporate, business unit and individual performance	Annual performance
PSUs (26-35% of compensation)	Rewards absolute and relative share price performance Fully at-risk with a 0% to 200% of target payout range (3 of 7 awards in last 7 years resulted in no payout as performance conditions were not met)	Three-year rolling performance cycles
Stock Options (26-35% of compensation)	Rewards absolute share price performance Only delivers value if our share price appreciates (as at December 31, 2012, 2 of 7 most recent annual grants are "in-the-money")	Seven-year term Vests over three years

Pay Alignment to Total Shareholder Return

We have a long standing pay-for-performance philosophy which is reflected in the design of our programs. A significant portion of the President and CEO's total direct actual compensation is variable and is linked to Suncor's performance, including financial results and stock performance. We look at the alignment of our pay programs with performance over short- and mid- to long-term periods, to ensure that our short-term actions lead to long-term increases in shareholder value.

In reviewing the alignment of our pay programs relative to performance, we look at two different pay perspectives, Pay Opportunity and Realizable Pay:

Pay Opportunity	Realizable Pay
Static numbers reported in the Summary Compensation Table Includes salary, annual incentive award and the estimated grant date values of PSUs and stock option awards Does not reflect the impact of share price on the ultimate value received through equity awards nor the actual number of PSUs earned which can be from 0% to 200%	Dynamic number that captures the current value of outstanding equity awards Includes salary, annual incentive award, and the current accrued value of outstanding stock options and PSUs The values ultimately received could be quite different depending on future performance

Based on available data and certain assumptions, the charts below indicate the alignment between Suncor's President and CEO pay over the past three years ⁽¹⁾ and TSR over one and three years for Pay Opportunity and Realizable Pay (which terms are described in the table directly above) relative to the CEOs of the Suncor Compensation Peers. This is due to a significant amount

26        SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

of pay being tied to performance, particularly to absolute share price, resulting in no value to date for 2 of 3 recent stock option grants, and relative TSR resulting in PSUs vesting close to target.

(1)

The charts reflect an average of Mr. George's total direct compensation for the years ended December 31, 2010 and 2011 and Mr. Williams' total direct compensation for the year ended December 31, 2012.

(2)

Data used for the Pay Opportunity chart is 2009 to 2011 for peer companies (latest management proxy circular disclosure data available) and 2010 to 2012 for Suncor.

(3)

Data used for the Realizable Pay chart is 2010 to 2012. For peer companies, it includes data from SEDI disclosure, where available, 2011 salaries aged (increased) by 4% and estimated 2012 bonuses based on 2012 estimated salaries times the 2011 actual bonus payment percentage.

(4)

Total Shareholder Return ranking based on average 1 year and 3 year TSR.

President and CEO Pay Multiple of Median Peer Group Pay

We also look at the pay opportunity for the President and CEO as a multiple of the median pay opportunity of Suncor Compensation Peers. The 2012 pay opportunity for the President and CEO compared to the 2011 pay opportunity for our peer group (most current data available) is just under a multiple of one (.99), reinforcing the market competitive position of pay relative to our peers.

President and CEO Pay at a Glance

On May 1, 2012, Mr. Williams became Suncor's CEO. His 2012 pay was adjusted in line with his appointment and in reference to pay levels among the Suncor Compensation Peers. As displayed in the corresponding graph, his 2012 total direct compensation was positioned at approximately 90% of our benchmarked total direct compensation structure. Through our succession planning process, we have managed a smooth transition process which benefits the organization in numerous ways, including continuity, and eliminates the additional costs that can be associated with recruiting an experienced external candidate.

Pay Programs Are Supported By Key Governance Practices

Some key practices include:

•

Share ownership guidelines – market competitive guidelines that range from 5 × salary for the President and CEO to 2 × salary for senior vice presidents. See "Our Approach to Executive Compensation – Executive Share Ownership Guidelines" on page 34 of this management proxy circular.

•

Post-employment hold periods for the CEO – a market leading approach where the President and CEO must maintain his share ownership requirement level through the first year following retirement. See "Our Approach to Executive Compensation – Executive Share Ownership Guidelines" on page 34 of this management proxy circular.

•

Claw back policy – a claw back policy was implemented in 2012 (the "Claw Back Policy"). See "Compensation Governance – Managing Compensation Risk – Key Mitigating Features" on page 31 of this management proxy circular.

•

Compensation risk assessment framework – a comprehensive compensation risk assessment was conducted in 2011, which included a detailed 22 element risk framework that is reviewed annually. See "Compensation Governance – Managing Compensation Risk" on page 30 of this management proxy circular.

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR        27

•

Employment and change of control agreements – the termination provisions contained in this agreement for our new President and CEO reflect a 24 month notice period. In addition, all stock option and PSU grants made beginning in 2012 have double trigger vesting, requiring both a change of control and termination of the executive. See "Termination Agreements and Change of Control Arrangements" on page 58 of this management proxy circular.

•

Supplemental executive retirement plan ("SERP") – our SERP design helps us attract skilled executives and retain them during periods of challenging share price performance. This is balanced by features that limit the pension, including restricted participation, a five year vesting period, and limits or caps. See "Compensation Disclosure of Named Executive Officers – Suncor Retirement Arrangements" on page 56 of this management proxy circular.

•

Annual incentive and PSU plan (the "PSU Plan") performance thresholds – key incentive plans include threshold performance levels for payouts.

•

Deferral of Annual Incentive – Suncor has an annual incentive deferral program that allows executives to take a portion or all of their AIP payment in DSUs. See "Compensation Governance – Managing Compensation Risk – Key Risk Mitigating Features" on page 31 of this management proxy circular.

COMPENSATION PHILOSOPHY

Our executive compensation policies and programs support Suncor's strategic growth and operational excellence goals, which are focused on increasing shareholder value through reliable operations, safety and environmental excellence, sustained performance and profitable growth.

Our philosophy is to compensate executives:

•

based on performance achieved, measured against challenging goals;

•

competitively with the Suncor Compensation Peers; and

•

with a mix of fixed and variable performance based compensation that enables Suncor to attract, engage and retain talented executives who have the capability to effectively manage Suncor's operations, assets and financial results in order to build and sustain long-term shareholder value.

Our compensation programs are competitive, designed around pay-for-performance objectives and are responsive to market changes. Actual rewards under short-, mid- and long-term programs are directly linked to Suncor's business results and increased shareholder value.

Executive Compensation Consultants

Towers Watson provides advice to the HR&CC, supports management in the area of executive compensation and provides services in other human resources areas, including pensions. Towers Watson has protocols in place to ensure that they are in a position to provide independent advice.

Meridian Compensation Partners ("Meridian") is retained by the HR&CC as its independent advisor.

Towers Watson was originally retained in February 2006 and Meridian was originally retained in February 2010.

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR        29

Towers Watson provides the HR&CC consulting support and information in the following areas:

•

expertise and advice in the development of compensation policies and programs for executives;

•

periodic updates on best practices, trends and emerging regulatory or governance matters related to executive compensation;

•

custom survey work benchmarking Suncor compensation in the marketplace; and

•

support in conducting a risk assessment of Suncor's compensation policies and programs.

Meridian's role is to review and provide advice to the HR&CC on analysis and recommendations put forward by management and Towers Watson. As the HR&CC's independent advisor, Meridian:

•

provides compensation advice and perspective to the HR&CC;

•

validates or challenges proposals, recommendations and the decision process followed; and

•

helps develop proposals and information for the HR&CC as needed.

The decisions made by the HR&CC may reflect factors and considerations other than as provided or recommended by our compensation consultants. During 2012, Towers Watson and Meridian met with the HR&CC chair and attended relevant sections of HR&CC meetings, as necessary.

Executive Compensation-Related Fees

Executive compensation-related fees paid by Suncor in 2011 and 2012 to Towers Watson and to Meridian are displayed in the table below.

Executive Compensation Consultant	Fees Paid related to 2011 ($)	Fees Paid related to 2012 ($)
Towers Watson	234 544	235 907
Meridian	31 774	21 458

All Other Fees

In addition to the fees disclosed above, Towers Watson assisted in certain matters related to pension and benefits, including, but not limited to, actuarial and accounting services. Total fees payable to Towers Watson for the foregoing services were $1,159,223 in 2011 and $802,918 in 2012, which included all fees payable to Towers Watson by Suncor not included under executive compensation-related fees in 2011 and 2012, respectively. Other than the fees disclosed above, no other fees were paid by Suncor to Meridian in 2011 and 2012.

The HR&CC pre-approves all material executive compensation-related fees paid to Towers Watson or Meridian. The Board does not pre-approve services provided by Towers Watson that do not relate to executive compensation-related services.

Managing Compensation Risk

Suncor's executive compensation policies and programs are designed to create appropriate incentives to increase long-term shareholder value. While the energy business by its nature requires some level of risk-taking to achieve returns in line with shareholder expectations, Suncor structures compensation plans and programs and has guidelines and policies to limit excessive risk.

Oversight Procedures

•

Suncor's strategic multi-year plan approved by the Board is believed to balance investment risk and reward, and assesses company and industry risks in advance to support planning, risk management and decision making.

•

As part of its governance, the Board has also overseen the development by management of Suncor's Enterprise Risk Management Program ("ERMP"). ERMP includes an entity-wide approach to risk identification, assessment, monitoring and management. In addition, the Audit Committee oversaw Suncor's adoption of a Trading Risk Management Policy. See page 3 of Schedule C to this management proxy circular.

30        SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

•

In the normal course of business, Suncor has financial controls that provide limits and authorities in areas such as capital and operating expenditures, divestiture decisions and marketing and trading transactions. These financial controls mitigate inappropriate risk-taking that could affect compensation.

"The HR&CC reviewed Suncor's compensation programs in 2012 using a 22 element Risk Framework and confirmed that Suncor's compensation policies and programs do not encourage excessive risk that is reasonably likely to have a material adverse effect on Suncor." •  During 2011, the HR&CC engaged Towers Watson to assist in developing and implementing a 22 element compensation risk framework (the "Risk Framework") for Suncor. The Risk Framework was designed to assist the HR&CC in assessing Suncor's compensation policies and programs to determine whether any components could encourage unacceptable excessive risk taking. The elements of the framework are categorized in four areas: pay philosophy and compensation structure, plan designs, performance metrics and governance. In connection with the development of the Risk Framework, Towers Watson met with members of the Board and senior management to understand Suncor's risk culture and risk profile, the interaction between material risks and compensation policies and programs and reviewed documentation from the ERMP and all compensation plans.

•

The HR&CC uses the Risk Framework on an annual basis to take account of any significant shifts in Suncor's business strategies or compensation policies and programs. The HR&CC reviewed Suncor's compensation programs in 2012 using the Risk Framework and confirmed that Suncor's compensation policies and programs do not encourage excessive risk that is reasonably likely to have a material adverse effect on Suncor.

Key Risk Mitigating Features

    Plan and Program Design

•

Total direct compensation for executives provides an appropriate balance between base salary and variable performance based compensation. For our Named Executive Officers, emphasis is not focused on one compensation component, but is spread across short-, mid- and long-term programs to support and balance sustained short-term performance and long-term profitable growth.

•

For our NEOs, typically 70% or more of their target total direct compensation is variable based on company, business unit and individual performance and the remaining 30% or less is base salary. Of the 70% or more of variable compensation, approximately 75% or more is mid- and long-term focused and approximately 25% or less is short-term focused. The weighting towards mid- to long-term compensation mitigates the risk of undue emphasis on short-term goals at the expense of long-term sustainable performance. More information on the pay mix for executives is provided on page 35 of this management proxy circular.

•

The AIP for all salaried employees is inherently designed to limit risk. Short-term incentive pay is earned based on achievement against a balanced, diversified mix of performance measures. The performance measures include both financial and operational targets. This balanced approach discourages focus on a single measure at the expense of other key factors (e.g., profitable growth at the expense of safety). The targets, results and payouts are stress-tested and reviewed by the HR&CC.

•

The funds available to provide annual cash payouts under the AIP are determined based on a scorecard for each business unit with consistent measurement across areas critical to Suncor's success. The performance measurement areas are personal and process safety, environment, reliability and people.

•

A threshold for payouts under the plan is established each year based on a minimum cash flow level requirement. Payouts under the plan are capped at 220% of target. The use of a number of key performance measurement areas and a threshold performance level that must be achieved for payouts under the AIP diversifies the risk under any one performance area.

•

Stock options vest over three years and have a seven year term, reinforcing the goal of building and sustaining long-term value in line with shareholder interests.

•

Our mid-term PSU Plan rewards relative TSR performance over three years versus our PSU peer group of companies, as described on page 61 of this management proxy circular. The three year performance period deters short-term focused

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR        31

decision making. There is no payout if relative TSR performance is in the bottom quartile, with a cap of 200% of target for relative TSR performance at the very top of the peer group and a sliding scale in between.

•

Under the DSU Plan, executives may elect annually to allocate either 50% or 100% of their AIP payment to DSUs. This feature in the DSU Plan is used by executives to assist in meeting share ownership requirements and defers annual incentive compensation, further encouraging a focus on long-term performance. For the 2012 performance period, 11 executives elected to take either 50% or all of their AIP payment in DSUs.

    Policy & Guidelines

•

Suncor's total compensation for executives is regularly benchmarked against a peer group of companies of similar size and scope approved by the HR&CC. This ensures that compensation is competitive with peers and aligned with Suncor's philosophy.

•

Stock options and PSUs are granted annually, thereby providing overlapping performance cycles that require sustained high levels of performance to achieve a consistent payout.

•

Suncor executives must achieve and maintain specific share ownership levels based on a multiple of their annual salary. A substantial ownership level in the Corporation assists in aligning executive interests with those of shareholders. The share ownership guidelines for executive officers are found on page 34 of this management proxy circular and range from 2 × salary for senior vice presidents to 5 × salary for the President and CEO. In addition, there is a further requirement for the President and CEO to maintain his share ownership requirement level through the first year following retirement.

•

The HR&CC and the Board provide strong oversight of the management of Suncor's compensation programs. The HR&CC has discretion in assessing performance under executive compensation programs to adjust metrics or the payouts based on results and events, and have used the discretion to reduce or increase payouts under certain programs in the past.

•

After completing the compensation risk assessment under the Risk Framework in 2011, the HR&CC recommended development of the broader Claw Back Policy for Suncor, which was adopted by the Board of Directors in 2012.

Pursuant to the Claw Back Policy, the Board may require that the NEOs and certain other key executive officers return incentive compensation paid to them if the financial results upon which the awards were based are materially restated due to intentional misconduct or fraud of the executive officer.

In situations where: (i) the amount of incentive compensation received by an executive officer or former executive officer to whom the policy applies was calculated based or contingent upon the achievement of certain financial results that were subsequently the subject of or affected by a material restatement of all or a portion of the Corporation's financial statements; and (ii) the executive officer or former executive officer engaged in intentional misconduct or fraud that caused, or potentially caused, the need for the restatement, as admitted by the executive officer or, in the absence of such admission, as determined by a court of competent jurisdiction in a final judgment that cannot be appealed; and (iii) the incentive compensation payment received would have been lower had the financial statements been properly reported, then the Board of Directors may, to the extent permitted by applicable laws and to the extent it determines that it is in the Corporation's best interest to do so, require reimbursement of the amount by which the after-tax incentive compensation received by such executive officer under the Corporation's annual and long-term incentive plans exceeded that which the executive officer would have received had the financial statements not been materially restated.

Conclusion

Given the oversight procedures and the key risk mitigation features of Suncor's compensation policies and programs described above, Suncor believes that it would be difficult for anyone in management acting alone, or acting as a group, to make "self-interested" decisions for immediate short-term gains that could have a material impact on the organization's financial or share price performance.

Executive Equity Compensation Hedging

Pursuant to Suncor's policies, executives are not permitted to engage in short selling in shares or purchase financial instruments (including, for greater certainty, puts, options, calls, prepaid variable formal contracts, equity swaps, collars or units of exchange funds) that are designed to hedge or offset a change in the market value of common shares or other securities held by an executive.

OUR APPROACH TO EXECUTIVE COMPENSATION

Pay-for-Performance  Philosophy.    Suncor maintains a strong pay-for-performance philosophy. Our philosophy is demonstrated in the mix of compensation provided to executives and the way we measure success. Compensation plans and practices are tied to our strategic business objectives. A significant portion of the total direct compensation of our senior

32        SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

executives is provided in variable performance based pay designed to reward superior business performance and increasing shareholder returns. This approach ensures alignment with shareholder interests and reinforces our pay-for-performance philosophy. For our senior executives, the incentive based pay is designed to reward successful short-, medium- and long-term performance in key business areas such as safety, environment, operating reliability, people, cash flow from operations and shareholder return, all of which enable the performance results and returns that are important to our shareholders.

Finding The Right Balance.    To deliver sustained and profitable long-term performance, it is essential that we attract, engage and retain talented, capable executives who can execute on current priorities and help position Suncor over the long-term for sustained success. To do this, we design our programs to provide an attractive and competitive total compensation opportunity. We believe we provide the right balance in our overall rewards program to achieve this through "total direct compensation", consisting of salary, annual incentive and annual mid- and long-term equity based incentives, and "indirect compensation", consisting of benefits and retirement-related programs. These programs are complimented with excellent career development opportunities and careful succession planning.

Defining Our Marketplace.    As the largest integrated energy company in Canada and fourth largest public energy company in North America by market capitalization, Suncor's size and business scope are key criteria in defining the marketplace and peer companies used to establish competitive compensation levels for our senior executives. This means that we need to look beyond Canadian energy companies and include US energy companies in our peer group in order to capture a sufficient number of companies of comparable size and complexity.

The peer group used to benchmark compensation levels for Suncor's senior executives in 2012, including the NEOs identified on page 25 of this management proxy circular, is approved by the HR&CC. The peer group is regularly reviewed by the committee and includes companies that are energy sector specific, have similar attributes to Suncor in terms of scope and complexity, and represent our market for executive talent.

Our peer group is comprised of 18 North American based energy companies and provides a robust sample to ensure that swings in compensation data in a single company do not unduly influence benchmark data. In Canada, we include pipeline companies, since there are fewer comparable large upstream and integrated energy companies and because pipeline companies form part of our labour market. In the U.S., where there are more large upstream and integrated companies, we limit the peer companies to comparable upstream and integrated energy companies.

For our senior executives in 2012, including the NEOs, annual total direct compensation is targeted at the median of the companies (the "Suncor Compensation Peers") identified in the table below. The same peer group is used for benchmarking director compensation. As noted below, Suncor ranks as one of the largest companies, as compared to the Suncor Compensation Peers, in relation to revenues, market capitalization and assets.

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR        33

A similar peer group of 18 companies is used in determining the relative TSR performance for our PSU grants as described beginning on page 61 of this management proxy circular. Fourteen companies are common to both benchmark groups. The difference in the peer groups reflects the specific purpose of each group (i.e. benchmarking of executive pay vs. comparing company shareholder return performance). We include only comparable North American upstream and integrated energy companies within the PSU peer group that have similar business strategies as evidenced by their share price characteristics and commodity price exposure.

Executive Share Ownership Guidelines

Suncor strongly believes that executives' interests should be aligned with the interests of Suncor's shareholders. One of the key ways we reinforce this is by requiring Suncor executives to have personal holdings in Suncor common shares or share equivalents equal to a multiple of their annual base salary.

Introduced in April 1997, and reviewed periodically to ensure they are market competitive and align with good governance practice, these guidelines visibly align senior management's interests with those of Suncor's shareholders and are supported by competitive benchmark data.

2012 and 2013 Guidelines.    The share ownership guideline level is to be achieved by the end of the fifth year after appointment to an executive position or promotion to a more senior executive position. On promotion to a more senior executive position, the prior guideline level must be maintained at the new base salary level. Suncor common shares and DSUs count toward fulfillment of the guidelines. The guidelines for 2012 remain competitive at all executive levels with the Suncor Compensation Peers and no changes have been made for 2013.

As at December 31, 2012, all NEOs were in compliance with the share ownership guidelines, as outlined in the table below.

NEO	Share Ownership Guidelines	Current Requirement at December 31, 2012	Holdings (1) (#)		Holding Value (1) ($)	Multiple of Annual Salary held in Shares

Share ownership guidelines were revised on January 1, 2010 for the Executive Vice President level. Messrs. Jackman and Little must achieve the designated share ownership level by the end of 2015.

(5)

Mr. Reynish commenced employment with Suncor on January 3, 2012. He must achieve his designated share ownership level by the end of 2017.

President and CEO Hold Requirement.    The President and CEO must maintain his share ownership level for one year following his retirement, which aligns with good governance practice. Mr. George retired on July 31, 2012 and he is in compliance with this requirement.

Total Direct Compensation Components: Base Salary + Annual Incentive Plan + Annual Mid- and Long-Term Incentives

Total direct compensation, made up of base salary, AIP and annual mid- to long-term incentives, is designed to reward short-term results and achievement of sustained longer-term performance in key business areas that enable the operational and financial results important to our shareholders. Suncor's pay-for-performance compensation philosophy for executives is reinforced in the mix of target total direct compensation provided.

34        SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

Incentive or variable performance based compensation represents a significant portion of total direct compensation for senior executives. The percentage of variable performance based versus fixed compensation increases as a portion of total direct compensation, with greater levels of responsibility. The chart below summarizes the elements of total direct compensation, as well as other compensation and benefit related elements.

For the leader of a business unit, the 60% weight at target for the Business Unit component of AIP is based half on the performance of the leader's business unit and half on the weighted average performance of all business units of Suncor. For the CEO and Chief Financial Officer, the 60% weight at target is based on the weighted average performance of all business units of Suncor. 2012 business units for the purpose of AIP are as follows: Oil Sands; In Situ; Exploration and Production ("E&P"); Refining and Marketing ("R&M"); Major Projects, and Oil Sands Ventures ("OSV").

Additional information regarding Suncor's 2012 performance is contained in Suncor's audited consolidated financial statements for the year ended December 31, 2012 and in the MD&A. The company's performance in 2012 provides context for compensation of the NEOs discussed in this management proxy circular.

The following summarizes Suncor's 2012 AIP performance and the 2012 performance and total direct compensation of the NEOs.

Suncor 2012 AIP Performance

Suncor's AIP rewards our NEOs and other annual incentive plan participants based on the performance achieved versus approved annual targets in key Corporate and Business Unit performance areas and for Personal performance. AIP awards are determined based on a combination of the weighted performance in these key areas.

The Corporate component of the AIP is comprised of two corporate wide financial measures. For the Business Unit component, each of Suncor's six business units has over 15 standard performance measures (a total of over 90 measures across the six business units). The measures are specific to the four areas of Suncor's operational excellence model: people and process safety, environment, reliability and people and have performance targets that are specific to each business unit to ensure line of sight for the employees in the unit.

The performance targets in each business unit are based on the budget (for example, production targets are based on budget) or on year over year improvement (for example, recordable injury frequency ("RIF") targets reflect year over year reductions). The overall score for the Business Unit component of the AIP is determined based on performance across each of the six business units and the weighting assigned to each business unit.

Governance of the AIP is comprehensive. Reviews of measures, weightings, targets, stretch and performance results are carried out at the business unit, corporate and HR&CC level.

Information on the Personal performance component of the AIP for the NEOs, including the calculation of the 2012 AIP award, can be found beginning on page 38 of this management proxy circular.

The opportunity for the Corporate and Business Unit component of AIP ranges from 0 to a maximum of 200, with a target score of 100.

(4)

Suncor's business unit guideline target weightings by Performance Area are as follows: 15% for each of Personal and Process Safety, Environment and People; and 55% for Reliability. However, these target weightings may vary slightly for individual business units, to place increased emphasis on a particular performance area for that year. For example, in 2012, the R&M business unit assigned a 15% target weighting to Environment and People, 20% to Personal and Process Safety, and 50% to Reliability. For 2012, the overall company target weightings for the four performance areas within the Business Unit component of AIP in the table above were as follows: 17% for Personal and Process Safety; 15% for Environment; 53% for Reliability; and 15% for People.

(5)

Certain measures may not be applicable to all business units. For example, Production is not a measure for the Major Projects business unit. In addition, certain business units may have additional unit specific measures. For example, the R&M business unit measures include specific reliability measures focusing on Retail, Wholesale, Distribution and Lubricants operations.

(6)

The Performance Area scores for the Business Unit component of AIP reflect the aggregate scores achieved across all of the business units. Performance for individual business units varied from the aggregate scores.

(7)

The AIP threshold CFOPS level below which AIP payments are reduced to 50% was $5.5 billion for 2012. The AIP threshold CFOPS level below which no payment would be made under the AIP was $2.8 billion for 2012.

The CFOPS total of $9.9 billion reflects a minor adjustment for AIP assumptions regarding CFOPS for Syria and Libya.

(10)

ROCE excluding MPIP of 13.2% excludes the impact of the impairment charge against the Voyageur upgrader project and impairment charges pertaining to assets in Syria and Libya. These impairment charges were taken into account in determining the Corporate performance factor used in the calculation of the AIP award for the NEOs and other executive leadership team members.

(11)

For 2012, a score of 100 required CFOPS of $8.7 billion and ROCE excluding MPIP of 10.6%; a maximum score of 200 required CFOPS of $11.1 billion and ROCE excluding MPIP of 17.4%.

2012 Performance of the President and CEO

The appointment of Steve Williams as Suncor's President and CEO with the retirement of Rick George in 2012, marked a smooth transition in the company's leadership. During Mr. Williams' first year as President, to which he was appointed in December 2011, and eight months as CEO, to which he was appointed in May 2012, he has re-affirmed and clarified the company strategy, while building a strong leadership team and engaging with investors and other key stakeholders.

Mr. Williams has taken over the leadership during a period when changes in the supply of crude have created increased market volatility and highlighted the importance of Canada increasing its market access options. In this context, Mr. Williams' strong focus on the profitable and responsible operation and development of oil sands resources, including rigorous attention to leveraging the company's integrated operations and becoming increasingly disciplined on costs has served to strengthen Suncor's position to deliver shareholder value and address stakeholder concerns over the long term.

Under Mr. Williams' leadership, the company achieved success in a number of areas and continues to be well-positioned to capitalize on business opportunities. These include:

•

Production: Overall production in 2012 of 549.1 mboe/d compared to 546.0 mboe/d in 2011.

•

Oil Sands Operating Costs: Oil Sands cash operating costs ⁽¹⁾ per barrel of $37.05 in 2012 compared to $39.05 per barrel in 2011.

•

Operational Excellence: Mr. Williams' continued focus on this area in 2012 is aimed at capturing benefits from improving the company's reliability performance.

•

Strength of Integrated Business Model: Mr. Williams successfully guided efforts to consistently leverage Suncor's integrated model to capture world pricing for approximately 96% of its refining output, protecting the company from a widening price differential between Brent, West Texas Intermediate and Western Canadian Select crudes. Earnings in this area were also bolstered by excellent reliability across Suncor's refining business where the company's refineries ran at 95% of capacity in 2012.

•

Financial Strength: Operating earnings for the year were $4.890 billion, while cash flow from operations was $9.745 billion. Overall economic conditions and oil sands reliability factored into results in this area and Suncor remains in a strong financial position, as evidenced by its strong cash flow, its strong balance sheet (net debt to cash flow from operations was 0.7:1) and its ability to return value to shareholders and fund growth with internal resources.

•

Capital Discipline: A renewed commitment to capital discipline led to a close examination of growth projects with a view to generating long-term value for shareholders. Mr. Williams has been clear in his communication with internal and external stakeholders that he is not interested in growth for growth's sake. He has demonstrated a willingness to make tough decisions and focus on high return projects designed to grow profitability. Furthermore, when investing in capital in growth projects, the company's focus will be guided more by cost and quality than by schedule.

The Board believes that Suncor's leadership succession and transition plan has been soundly executed, and Mr. Williams has effectively developed and implemented Suncor's business strategy in partnership with the senior leadership team and Suncor's more than 13,000 employees. The Board has also identified that Mr. Williams, early in his tenure as President and CEO, has worked diligently to keep the Board fully apprised of issues and strategic initiatives relating to the company's financial and operational performance. As a result, the Board evaluated Mr. Williams' performance as "strong" in 2012.

The following is a summary of Mr. Williams' key accomplishments in 2012 for each of the performance areas:

Financial and Operating Results

2012 Goals•  Drive improved shareholder value       and ROCE together with an       increased effectiveness of       investor relations.   2012 Performance Summary•  Net earnings of $2.783 billion.    •  Cash flow from operations of       $9.745 billion.    •  Net debt of $6.632 billion.    •  Total average production of       549.1 mboe/d, including       359.2 mbbls/d from Oil Sands       (including Syncrude) and       189.9 mboe/d from E&P.

2012 Performance Highlights Suncor's financial performance in 2012 remained strong and positioned the company well for execution of its business strategy, including development of growth projects designed to deliver appropriate returns to shareholders. The company recorded net earnings of $2.783 billion, while cash flow from operations remained steady at $9.745 billion during the same period. Net debt at year-end 2012 was $6.632 billion, which decreased from $6.976 billion at December 31, 2011. This debt level is well under the company's target of 2:1 net debt to cash flow from operations ratio (actual ratio was 0.7:1). On the operational front, total average production for 2012 was 549.1 mboe/d, which included 359.2 thousand barrels per day ("mbbls/d") from Oil Sands (including Syncrude) and 189.9 mboe/d from E&P operations. Oil Sands production in the last quarter of 2012 reached record levels of 342.8 mbbls/day (excluding Syncrude). Under Mr. Willliams' leadership, Suncor was able to effectively capture value for shareholders by leveraging its integrated business model to take advantage of market opportunities throughout the value chain. The Board believes that the financial strategy, aimed at supporting the business plan, managing risk, providing financial flexibility and optimizing the cost of capital is appropriate and is being effectively stewarded by Mr. Williams and Suncor's senior leadership team. The Board believes that while the company compares favourably to its peers on key balance sheet, capital structure and cash flow metrics, progress needs to be made on improving ROCE metrics. The growth project evaluation work that was undertaken in 2012 has helped to better position the company for improvement in this area.

Operational Excellence, Safety and Environmental Performance

2012 Goals•  Accelerate the journey to transform       Suncor into a more disciplined       process-focused organization.    •  Drive improvement in operating       performance at Firebag Stage 4       start up.    •  Drive continuous improvement       through Operational Excellence       with focus on safety, environment,       reliability and people.   2012 Performance Summary•  Operational excellence objectives       and organizational priorities       clarified.    •  Major turnarounds at Oil Sands       completed on time, scope and cost.    •  Successful ramp up of Firebag       Stage 4 and commissioning of       Firebag Stage 4.    •  Improvements in safety and       environmental performance.

2012 Performance Highlights Mr. Williams has ensured a strong focus on operational excellence at the company, ensuring that Suncor and its employees adopted an extensive set of operational excellence objectives in 2012. He also guided an intensive baseline self-assessment on processes across the organization, leveraging the company's Operational Excellence Management System ("OEMS") to drive performance improvement. While upgrader reliability challenges and offshore facility turnaround delays were disappointing elements of the company's 2012 performance, progress continues to be made on Suncor's journey to operational excellence. This included turnarounds being completed on time and cost effectively at Oil Sands, and an increase to the nameplate capacity of one of the company's refineries. At In Situ, production continued to ramp up on Firebag Stage 3, reaching full capacity. Firebag Stage 4 achieved first oil in late 2012 and is expected to be 15% under the announced cost of $2 billion. Suncor's performance on safety and environment has seen steady improvement. Total Injury Frequency ("TIF") in 2012 improved 21.1% over 2011, while RIF improved 19.2% for the same period. Progress continues towards the company's environmental performance goals on water consumption, land reclamation, energy efficiency, and air emissions.

Profitable Growth through Cost Control and Project Execution

2012 Goals•  Drive to further strengthen OSV       organization and drive value       through strategic partnerships.    •  Drive improved cost control in Oil       Sands and In Situ.    •  Drive improvements in growth       projects. Increase returns by       managing inflation, scope control,       field execution, cost control and       quality.   2012 Performance Summary    •  Renewed focus on capital discipline       to align with long term strategy and       drive shareholder value.    •  Measures set to monitor       achievement of long-term strategy.

2012 Performance Highlights The company continued to focus on cost control and effective project execution in 2012. In addition to successfully establishing the OSV Business Unit to progress projects with partners, Mr. Williams worked to put robust and effective management processes in place to ensure increased focus on capital discipline and profitable investment in sustaining and growth capital. Specific measures have been put into place to monitor achievement of the long-term strategy, including ROCE, TSR, annual growth targets, reliability and cost targets. Oil Sands cash operating costs per barrel were $37.05 in 2012 compared to $39.05 per barrel in 2011. A renewed commitment to capital discipline led to a close examination of growth projects with a view to generating long-term value for shareholders. Mr. Williams has been clear in his communication with internal and external stakeholders that he is not interested in growth for growth's sake. He has demonstrated a focus on high return projects designed to grow profitability. Furthermore, when investing in capital in growth projects, the company's focus will be guided more by cost and quality than by schedule.

Leadership on Policy and Industry Issues

2012 Goals•  Continue to strengthen Suncor's       relationships with government at       provincial, federal and       international levels.    •  Continue to take a lead role on oil       sands reputation to maintain       social licence to grow.   2012 Performance Summary•  Key relationships established with       government, Aboriginal leadership,       influencers and stakeholders.    •  22 speeches delivered to external       audiences and CEO media visibility       nearly doubled.    •  Industry collaboration advanced       through Oil Sands CEO Council       and launch of COSIA.

2012 Performance Highlights Mr. Williams has made efforts on behalf of Suncor to engage with government, Aboriginal leaders, environmental organizations and stakeholders in discussions about energy, environment and the economy. Since his appointment as President and CEO, Mr. Williams has been focused on the development of key relationships, including with federal and provincial elected officials, key bureaucrats, industry peers and other key influencers. He has been an active participant on the Canadian Council for Chief Executives. Mr. Williams has ensured that Suncor has had a voice in significant policy recommendations made by the Energy Policy Institute of Canada, the Canadian Association of Petroleum Producers and other industry associations. He has also participated directly and led Suncor's recommendations to governments on critical areas for policy progress, including regulatory, market access, energy literacy and conservation, innovation and carbon management. Mr. Williams has also worked to engage constructively with Aboriginal leaders, environmental non-governmental organizations, community groups and other stakeholders. In addition to delivering a keynote address at the Globe Sustainability conference in Vancouver in early 2012, he delivered 22 external presentations to a range of investor, stakeholder and community audiences. Suncor's CEO media visibility (which included both Mr. Williams and his predecessor, Mr. George) nearly doubled over the previous year and was the highest among its peers, as highlighted by third party analysis. Mr. Williams also played a lead role in driving industry collaboration through the Oil Sands CEO Council, including the public launch of Canada's Oil Sands Innovation Alliance ("COSIA") and the transition of the Oil Sands Leadership Initiative (OSLI) to the new entity. He has also influenced the Council's priorities on regional socio-economic development, safety, operational excellence, policy and communications.

In leading the downstream business, Mr. Jackman contributed to Suncor's operational and financial success, particularly by helping the company leverage its integrated business model to create value for Suncor and its shareholders.

Mr. Jackman led efforts in 2012 to deliver R&M net earnings and cash flow from operations of $2.13 billion and $3.15 billion, respectively, excluding renewables.

Strong reliability at all operating facilities enabled the company to maximize value for shareholders using low crude pricing inputs at its inland refineries (Edmonton, Denver and Sarnia) to capture Brent crude-based product pricing on 96% of Oil Sands production.

The company also continued to improve reliability at its refining operations. Continuous improvements at the Montreal and Commerce City refineries enabled total R&M nameplate crude capacity to be increased to 455,000 barrels per day ("bbls/d") effective as of January 1, 2012 and improvements at the Edmonton refinery resulted in a further increase of 5,000 bbls/d in nameplate capacity effective as of January 1, 2013, versus total R&M nameplate crude capacity of 443,000 in 2011. Overall refinery utilization averaged 95%.

Retail and wholesale marketing programs delivered above target net earnings with a sales volume in core wholesale channels exceeding sales in 2011 by 3.5%. Through its Petro-Canada branded outlets, R&M continues to be the leading retailer in Canada, as measured by market share in urban areas. The Lubricants business achieved annual margin targets on high value-added channels and double digit percentage growth in target foreign markets versus 2011.

Improvements were also achieved in personal and process safety management, with R&M TIF of 0.32 per 200,000 man hours worked, versus a target of 0.55. A reduction of 44% in environmental regulatory non-compliances was also achieved.

Attraction and retention remained a focus, with the implementation of an R&M human resource plan to meet hiring and capability development over the next ten years.

2012 Compensation

Base Salary.    Mr. Jackman did not receive a base salary increase in 2012 as his salary is at the top of the competitive salary range for the Executive Vice President level compared to the Suncor Compensation Peers.

Annual Incentive.    The Executive Vice President, Refining and Marketing's award for 2012 was $1,000,000. The award is 178% of the target award level of $563,000 or 75% of his base salary. The range for the AIP award is from 0% to a maximum of 220% of the target award level. The Corporate and Business Unit performance factors used in determining Mr. Jackman's AIP award are as approved by the HR&CC.

Mark S. Little, Executive Vice President, Oil Sands and In Situ

Mr. Little was appointed to the position of Executive Vice President, Oil Sands in 2011. The In Situ business was added to his portfolio in early 2012. As Executive Vice President, Oil Sands and In Situ, his role is to lead improvements in competitiveness, safety and sustainability at Suncor's oil sands mining, extraction and upgrading operations, as well as at the company's various in situ facilities in Northern Alberta. Mr. Little joined Suncor in November 2008.

2012 Goals•  Lead Suncor's journey to Operational
      Excellence in the Oil Sands &
      In Situ business units.

   •  Achieve budget in terms of safety,
      volume, unit cost, and capital metrics.

   •  Lead the ramp up of Firebag Stage 3
      and achieve first steam on Firebag
      Stage 4.

  2012 Performance Summary•  Continued Oil Sands and In Situ's
      journey to Operational Excellence.

   •  Achieved record performance on safety,
      progress towards environmental goals.

   •  Achieved successful ramp up of Firebag
      Stage 3. First steam achieved on Firebag
      Stage 4 by year end 2012 and is
      expected to be under budget.

   •  Continued focus on improving reliability
      and performance.

   •  Increased engagement with external
      stakeholders. 2012 Performance Highlights

Mr. Little's efforts in 2012 were focused on operational excellence initiatives and production reliability from Suncor's Oil Sands and In Situ operations, including the Firebag complex.

A key initiative he led to drive performance improvements and reduce costs within the business unit was the realignment of the In Situ business and the establishment of a regional development team, including technical optimization and integration leadership. Mr. Little also engaged employees in other parts of the company to progress the operational excellence effort.

Significant progress was made in Oil Sands and In Situ in terms of safety and environmental performance, with record results being achieved on safety, risk and consequence events, loss of containment, regulatory non-compliance, reclamation and SO₂ emissions. The company also continued implementation of TRO_TM, its tailings management system, which is expected to significantly accelerate the pace of tailings reclamation. Energy intensity and net water withdrawal improvements were also achieved.

Suncor continued to set all time monthly production records throughout the year, along with a quarterly production record in the third quarter of 2012. Total average annual production increased by 20,100 bbls/d in 2012 from the previous record of 304,700 bbls/d in 2011.

A key factor in the increase in production was the successful ramp up of Firebag Stage 3. Firebag Stage 4 achieved first oil in late 2012 and is expected to be 15% under the announced cost of $2 billion.

The focus on reliability continued, however an unplanned outage at one of the company's upgraders offset prior gains in price realizations from product mix. Under Mr. Little's leadership, Oil Sands and In Situ continue their focus on reliability in their operations to address lost opportunity values within the upgrader complex, with a specific focus on the U2 upgrader.

Mr. Little has also worked to engage with the external community, including active involvement in investor tours, as well as meetings and presentations with government, Aboriginal neighbours, suppliers and stakeholder meetings. He also played a key role in high profile media events and took a strong leadership role in Alberta's Drug and Alcohol Risk Reduction Project and Suncor's random drug testing program roll out.

2012 Compensation

Base Salary.    Mr. Little received a base salary increase of 14% effective March 1, 2012, taking his annual salary to $570,000. The increase recognizes the growth in the scope of his role with the addition of responsibility for Suncor's In Situ business unit at the beginning of 2012 and recognizes his demonstrated capability in his role.

Annual Incentive.    The Executive Vice President, Oil Sands and In Situ's award for 2012 was $580,000. The award is 135% of the target award level of $428,000 or 75% of his base salary. The range for the AIP award is from 0% to a maximum of 220% of the target award level. The Corporate and Business Unit performance factors used in determining Mr. Little's AIP award are as approved by the HR&CC.

Working within a joint venture framework, he ensured the team placed a high priority on operational discipline, collaboration and ensuring the company's capital investments provide appropriate returns to shareholders.

Given changing market dynamics and Suncor's ongoing commitment to deliver shareholder value, Mr. Reynish also led a thorough optimization review of the company's joint venture projects. This review included looking at internal rates of return by reducing growth and sustaining capital costs, controlling operating costs and optimizing production capacity, all while ensuring Suncor's high standards and commitments to safety and the environment were not compromised.

The scope and scale of the various OSV projects also required that the company manage risks associated with growth. Mr. Reynish ensured a rigorous joint venture risk management process was put into place as the OSV organization was built and worked to assess projects. This included continuing to ground the OSV team's work in the OEMS.

Mr. Reynish also worked to ensure understanding of OSV's structures and projects, as well as associated business opportunities and risks through a series of presentations in various areas and levels throughout Suncor.

2012 Compensation

Base Salary.    Mr. Reynish joined Suncor on January 3, 2012 and thus did not have a salary review in 2012.

Annual Incentive.    The Executive Vice President, Oil Sands Venture's award for 2012 was $485,000. The award is 129% of the target award level of $375,000 or 75% of his base salary. The range for the AIP award is from 0% to a maximum of 220% of the target award level. The Corporate and Business Unit performance factors used in determining Mr. Reynish's AIP award are as approved by the HR&CC. The impairment charges related to the Voyageur upgrader project and pertaining to assets in Syria and Libya were taken into account to reduce the Corporate performance factor used in the calculation of the AIP award for the NEOs and other executive leadership team members. The Personal performance factor is determined based on the assessment of Mr. Reynish's performance by the President and CEO. The calculation of his AIP award amount is comprised of two steps as displayed below.

Mid- to Long-Term Incentive.    The 2012 annual equity component of Mr. Reynish's competitive total direct compensation was made in February 2012. The grant of PSUs and stock options considered the market target value at the median of the Suncor Compensation Peers. On joining Suncor, Mr. Reynish was also awarded a one-time grant of DSUs in recognition of a loss of compensation experienced in leaving his previous company. For further details on Mr. Reynish's 2012 equity award and total compensation for 2012, see the "Summary Compensation Table" on page 54 of this management proxy circular.

Total Direct Compensation.    For reference, the chart below displays Mr. Reynish's total direct compensation for 2012. The mid- and long-term incentive amounts are the deemed value of the equity grants (at the date of grant, and as calculated using the methodology described under the Summary Compensation Table on page 54 of this management proxy circular) and will differ from the ultimate value realized from the awards based on Suncor's relative and absolute share price performance over time.

Compensation of the Former CEO

Mr. George stepped down as CEO on May 1, 2012 and retired from Suncor on July 31, 2012. The information that follows reflects the Board's decisions with regard to Mr. George's 2012 compensation.

Base Salary.    The former CEO did not receive a base salary increase in 2012.

Annual Incentive.    The Board approved an annual incentive award of $750,000 for 2012. In determining the amount of the pro-rated award, the Board considered the former CEO's target annual incentive, the annual incentive results and his period as CEO in 2012 prior to stepping down from the position. The impairment charges related to the Voyageur upgrader project and pertaining to assets in Syria and Libya were taken into account to reduce the AIP award for Mr. George.

Mid- to Long-Term Incentive.    The Board approved an annual equity award for Mr. George in February 2012 consistent with Suncor's policy. In making the grant of PSUs and stock options, the Board considered Mr. George's performance and his exceptional leadership during his tenure as CEO. Notably, the value of the award approved by the Board has been partially reduced, as the term of the stock options is automatically dropped from seven to three years on retirement pursuant to the SOP. The Board believes that it is important that Mr. George's economic interests remain aligned with shareholders into retirement. In addition, Mr. George is required to maintain his share ownership level through the first year of his retirement.

Total Direct Compensation.    For reference, the chart below displays the former CEO's total direct compensation for the past three years. The mid- and long-term incentive amounts are the deemed value of the equity grants (at the date of grant, and as calculated using the methodology described under the Summary Compensation Table on page 54 of this management proxy circular) and will differ from the ultimate value realized from the awards based on Suncor's relative and absolute share price performance over time.

Executive Compensation Alignment with Shareholder Value

The Board recognizes that in an industry subject to commodity price cycles, Suncor's focus is on long-term shareholder value growth. Suncor's common shares were valued at $32.71 on the TSX at December 31, 2012, an increase of approximately 11% over the year before. From 2007 to 2012, Suncor's share price decreased by approximately 36%. The following performance graph shows Suncor's total cumulative shareholder return for the past five years.

Performance Graph ⁽¹⁾⁽²⁾

(1)

The graph reflects the total cumulative return, assuming the reinvestment of all dividends, of $100 invested on December 31, 2007 in each of Suncor common shares, the S&P/TSX Composite (TRIV) Index and the S&P/TSX Energy (TRIV) Index.

(2)

The year-end values of each investment shown on the graph are based on the share price appreciation plus dividend reinvestment.

Total Direct Compensation

The expected value and current value of total direct compensation for the NEOs, for the period from 2008 to 2012, are illustrated in the graph below. Over this period, the current value at December 31, 2012 of total direct compensation for the NEOs was approximately 21% lower than the expected value as determined in accordance with the methodology described in the footnotes for the Total Direct Compensation Graph. The lower current value of the total direct compensation for the NEOs is consistent with the trend of total return on investment indicated for Suncor in the performance graph provided above.

Suncor's strong operational performance in 2010, 2011 and 2012 resulted in above target payouts under the AIP component of total direct compensation. However, this operational performance has not been reflected in our share price. At December 31, 2012, the current value of annual mid- to long-term incentive awards granted during 2008 to 2012 was 33% lower than the expected value, as determined in accordance with the methodology described in the footnotes for the Total Direct Compensation Graph. This reflects the high proportion of variable, performance based compensation in the total direct compensation provided to the NEOs.

The downturn in the market and decline in Suncor's share price would have resulted in outstanding option awards for 2008, 2011 and 2012 having no cash value if exercised at December 31, 2012. In addition, the Suncor PSU awards, granted in 2008, provided no payment as the threshold level of relative TSR performance was not achieved. The lower current value at December 31, 2012 of the annual mid- to long-term incentive awards demonstrates alignment with Suncor's pay-for-performance philosophy and shareholder interests.

President and CEO Look Back

In 2006, the HR&CC introduced the practice of annually reviewing a broader analysis of the total compensation earned and accruing to Mr. George since his appointment and relating it to the TSR during the same period. With the retirement of Mr. George in 2012 and appointment of Mr. Williams as CEO, the committee will continue this governance practice, recognizing that the relevance of the look back analysis increases with the President and CEO's time in the position.

52        SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

Looking Ahead to 2013:

The HR&CC approved a 4% budget for salary increases for executives in 2013 based on competitive benchmarking. No changes were made to annual incentive or long term incentive ("LTI") target levels expressed as a percent of base salary based on benchmarking these components of total direct compensation with the peer group median levels.

For LTI awards made after January 1, 2013, the compensation valuation methodology used by Suncor to value the LTI awards disclosed in the Summary Compensation Table will be changing. The current binomial valuation methodology used to determine grant date fair values will change to determining the LTI values based on the accounting valuation.

Most large Canadian companies have or are moving to accounting valuation for LTI awards (consistent with practice and disclosure requirements in the United States). This will simplify disclosure as the LTI grant date fair values disclosed in the summary compensation table will be aligned more closely with accounting values. This change will be reflected in Suncor's management proxy circular for the 2014 annual meeting.

Effective February 4, 2013, the Board approved the grant of options and PSUs to the Named Executive Officers as described in the table below, under the terms of the SOP and PSU Plan.

Valuation Disclosure for Share-Based Awards.    Consistent with disclosure requirements, as outlined under Form 51-102F6 – Statement of Executive Compensation, the following summarizes (a) the methodology and key assumptions used to calculate the fair value of awards at grant date and (b) discloses where the accounting fair value, as determined in accordance with International Financial Reporting Standards ("IFRS"), is different than the fair value of awards at grant date and why.

For share-based awards, the fair value of awards at grant date, as shown in the Summary Compensation Table above, reflects the number of PSUs awarded multiplied by the grant date fair value price calculated using Towers Watson's binomial valuation methodology. The HR&CC used this methodology in making its decisions regarding incentive grants since it was applied consistently in its competitive market analyses. Effective January 2013, Suncor moved to the accounting valuation methodology. For grants on or after January 1, 2013 this methodology will be the basis for disclosing the value of share-based awards in the executive compensation disclosure.

Effective January 1, 2011, as a result of the company's adoption of IFRS and for accounting purposes, PSUs are valued based on the Monte Carlo simulation methodology. For grants in 2010, accounting fair values have been restated to reflect this methodology.

A summary of the grant date fair values calculated using Towers Watson's binomial methodology and key assumptions used under this methodology as well as the accounting fair values at the end of the financial quarter following the grant date and the variance between the values based on the two methodologies is provided below. The variance between the grant date fair values and accounting fair values for each award is the result of a different methodology being applied to value the awards and the date the value is reported (grant date versus end of financial quarter).

Valuation Disclosure for Option-Based Awards.    Consistent with disclosure requirements, as outlined under Form 51-102F6 – Statement of Executive Compensation, the following summarizes (a) the methodology and key assumptions used to calculate the fair value of awards at grant date and (b) discloses where the accounting fair value, as determined in accordance with IFRS, is different than the fair value of awards at grant date and why.

For option-based awards, the fair value of awards at grant date, as shown in the Summary Compensation Table above, reflects the number of options awarded multiplied by the grant date fair value price calculated using Towers Watson's binomial valuation methodology. The HR&CC used this methodology in making its decisions regarding incentive grants since it was applied consistently in its competitive market analyses. Effective January 2013, Suncor moved to the accounting valuation methodology for disclosing the value of option-based awards in the executive compensation disclosure.

For accounting purposes, options are valued based on the Black-Scholes methodology.

A summary of the grant date fair values calculated using Towers Watson's binomial valuation and key assumptions used under this methodology as well as the accounting fair values and the variance between the values based on the two methodologies is provided below. The variance between the grant date fair values and accounting fair values for each award is the result of a different methodology being applied to value the awards.

Suncor Retirement Arrangements.    The Suncor Energy Pension Plan is a registered pension plan that provides retirement income to Suncor employees, including Messrs. Williams, George, Demosky, Little and Reynish. Retirement income is based entirely on a defined contribution account balance, or depending upon the employees' eligibility, based on a combination of a defined benefit pension payment, including an employee-paid benefit feature, and a defined contribution account balance. Messrs. Williams, George, Demosky and Little participate in the combination provision of the plan; Mr. Reynish participates in the defined contribution provision.

In addition to the pension provided under the Suncor Energy Pension Plan, certain executive officers may receive supplemental retirement payments under the terms of the SERP. Under the terms of the SERP, any new participants must be approved by the HR&CC.

"The SERP features balance the need to attract mid-career executives with responsible governance of pension obligations."
The SERP is a non-registered supplemental retirement arrangement designed to attract mid-career executives with a competitive career based pension that features an up-front accrual. This attraction element is balanced by features that limit the executive pension by: a) requiring that an executive provide five years of service to be entitled to SERP benefits, which is three years more than the service required under the Suncor Energy Pension Plan; b) limiting service to Suncor related experience only, both for vesting and benefit accrual purposes; c) effective January 1, 2012, limiting the executive's total pension to 70% of executive remuneration; and d) effective January 1, 2012, limiting executive remuneration to a maximum of two times base

salary (base salary plus annual incentive target bonus of up to 100% of base salary). All of the Named Executive Officers, with the exception of Mr. Jackman, are members of the SERP. Additional details of the SERP follow.

•

Executive employment commences at the date of entry into the SERP. Generally, there is no recognition of service for non-Suncor related employment.

•

The SERP pension is based on the executive's remuneration multiplied by a combined accrual rate of 5%, multiplied by the number of years of executive employment plus a pension formula percentage determined in respect of the Suncor Energy Pension Plan relating to service prior to becoming an executive, limited to a combined accrual rate of 50%. The pension increases by an additional 1.5% of the executive's remuneration for executive employment earned, generally after the executive completes 25 years of service. Effective January 1, 2012, the total pension is limited to 70% of the executive's remuneration, as described below.

•

Executive remuneration is an annualized amount of the average salary plus target bonus for the best consecutive 36 months of the last 180 months of continuous service. Effective January 1, 2012, target bonus, other than as grandfathered for Mr. George, cannot exceed 80% of base salary for Senior Vice Presidents and Executive Vice Presidents and 100% for other executives, including the CEO.

•

Five years of executive employment including, where applicable, the period of notice of termination or payment in lieu of such notice, are required for rights under the SERP to vest. Executive officers with less than five years of executive employment are not eligible to receive supplemental retirement payments under the SERP except in the event of a change of control, or a loss of employment upon or after the occurrence of certain specified events.

•

SERP payments for retirement prior to age 60 will be reduced by ⁵/12 th of 1% for each month that the executive officer retires before age 60; no reduction is applied for retirement after age 60.

56        SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

•

The normal form of payment on retirement, and the basis on which benefits in the table under "Defined Benefit Plans" are computed is: for married employees, joint and survivor, with 50% to the non-member surviving spouse; and for single employees, for life, with ten years guaranteed.

•

A portion of retirement income is payable by the Suncor Energy Pension Plan, including both the defined benefit and defined contribution components, and a portion is payable under the SERP. Canada Pension Plan payments are in addition to payments under the Suncor pension plans.

•

Trust arrangements have been established to provide for the long-term funding of Suncor's non-U.S. taxpayer SERP obligations.

Petro-Canada Retirement Arrangements.    The Petro-Canada Retirement Plan is a registered pension plan that provides retirement income to certain Suncor employees who worked for legacy Petro-Canada prior to the merger, including Mr. Jackman. The defined benefit provision of the plan has been closed to new entrants since July 1, 1996. Mr. Jackman continues to participate in this portion of the plan.

In addition to his pension under the Petro-Canada Retirement Plan, Mr. Jackman is also entitled to receive supplemental retirement payments under the terms of his individual retiring allowance agreement. Under his retiring allowance agreement, the normal retirement benefit for Mr. Jackman equals 2% per year of credited service to a maximum of 35 years, multiplied by the average of the highest 36 consecutive months of base salary in the final 120 months of service. At age 65, the benefit is reduced by an adjustment equal to 50% of the total of Canada/Quebec Pension Plan plus Old Age Security benefits, pro-rated for years of service less than 35.

Early retirement under Mr. Jackman's individual retirement allowance agreement requires our consent for commencement before age 65. In the event of early retirement, the normal retirement benefit is reduced by 0.25% for each month that the executive officer retires before age 60; no reduction is applied for retirement after age 60. Normal and early retirement benefits are indexed annually for Mr. Jackman to 50% of the consumer price index, commencing after age 60, subject to a maximum indexing adjustment of 5% for any year. The normal form of payment on retirement for Mr. Jackman, if married, is joint and survivor, with 50% to the non-member surviving spouse subject to a minimum of 60 monthly payments. Mr. Jackman's pension obligation is secured by a letter of credit held by a trust.

Credited service includes 11 years of service with an affiliated Suncor company for determining the additional 1.5% accrual rate applicable after 25 years of service for Mr. George and 10 years of industry service granted to Mr. Jackman at date of hire. For Mr. Demosky, credited service reflects executive employment plus 3 years of service accrued under the Suncor Energy Pension Plan prior to becoming an executive.

(2)

Represents the estimated annual pension, excluding any employee paid ancillary benefits, where applicable, that would be received by the Named Executive Officer upon retirement at age 65 based on actual or projected pensionable service to the stated date and actual pensionable earnings as at December 31, 2012.

(3)

The defined benefit obligation is the estimated value of the pension obligation to the date indicated using the actuarial assumptions and methods that are consistent with those used in determining the pension obligation as disclosed by Suncor in its consolidated financial statements. See note 22 in Suncor's consolidated financial statements for the year ended December 31, 2012. The methods and assumptions used to determine the estimated amounts may not be identical to those used by other companies and as a result may not be directly comparable to the amounts disclosed by other companies.

(4)

Compensatory change represents the increase in the pension obligation for 2012 related to the annual service cost, compensation changes higher or lower than assumptions and the impact of plan changes, if any. This amount may fluctuate significantly from year-to-year as changes in compensation impact the pension obligation for all years of credited service.

(5)

Includes items such as interest on the obligation and the impact of changes in the discount rate assumption.

(6)

The Defined Benefit Obligation in respect of Mr. Williams, as previously disclosed at December 31, 2011 in the amount of $10,938,463 has been restated to reflect his appointment as President, effective as of December 1, 2011, which was not previously included in the 2011 amounts.

Mr. George retired in 2012. $1,870,390 represents Mr. George's pension at his retirement date.

Defined Contribution Plans.    Under the combination provision of the Suncor Energy Pension Plan, applicable to Messrs. Williams, George, Demosky and Little, Suncor makes contributions to the defined contribution accounts for all employees of 1% of basic earnings, plus up to an additional 1.5% of basic earnings on a 50% matching basis, subject to maximum contribution levels. For employees participating only in the defined contribution provision, including Mr. Reynish, Suncor makes contributions to the defined contribution accounts of 5% to 9% of basic earnings depending upon years of service with the company, plus up to an additional 2.5% of basic earnings on a 50% matching basis, subject to maximum contribution levels.

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR        57

Under the Suncor Energy Pension Plan, employees may invest the balance of their accounts in a broad range of investment funds made available by the plan; an employee's investment return is based upon the market returns earned by each fund in which the employee has chosen to invest his contributions. At retirement, employees may transfer the balance of their accounts to a pension account as prescribed by law or the company may purchase an annuity on behalf of the employee.

The following table summarizes the defined contributions accounts of each of the Named Executive Officers.

TERMINATION AGREEMENTS AND CHANGE OF CONTROL ARRANGEMENTS

Termination Agreements.    Suncor has employment termination agreements with each of the Named Executive Officers except for Mr. George. The termination agreement with Mr. George ended in 2012 at the effective date of his retirement from the company.

Except for Mr. Jackman, such individuals are compensated based on their remuneration, in the event of termination of employment ("Termination Event") by Suncor, other than for just cause, and by the individual within 120 days following a constructive dismissal event.

"In 2011, the HR&CC approved amendments to termination agreements that were implemented for new senior executive participants in 2012. The amendments provide for the pro-rating of payments for PSU and RSU grants held at the dismissal date, based on the number of months employed during the term of the PSU or RSU grant."
Notice Period ProvisionsFor the NEOs other than Mr. Jackman, should a Termination Event occur, the termination agreements provide a 24-month notice period. Cash payments are provided for base salary and targeted annual incentive during the notice period, for SOP and ESP options which, but for the Termination Event, would have become exercisable during the notice period, and for PSUs and RSUs that would pay out during the notice period based on a performance factor calculated as at the date of termination, if applicable. The foregoing individuals receive credited service under the SERP for the notice period.


Upon a Termination Event occurring, the notice period for Mr. Jackman is the lesser of 30 months or 65 minus his age at the time of the Termination Event ⁽¹⁾. A lump sum payment is provided equal to his base salary as of the date of termination and annual incentive over the notice period and the value of his mid- or long-term incentives, which are equal to the lesser of the value of the grant of options to him in February 2000 and the value of the options granted to him in 2001, and in each successive year thereafter. For the purpose of calculating Mr. Jackman's retirement benefit, service is increased by the notice period and he is deemed to have earned the base salary as of the termination date for the duration of the notice period.

(1)

Based on Mr. Jackman's age at December 31, 2012, and assuming a Termination Event at this date, his notice period is less than 12 months.

58        SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

Double Trigger Provisions and Change of Control

Suncor's termination agreements with Messrs. Williams, Demosky, Little and Reynish are "double trigger", and as such provide for payments based only upon involuntary termination or constructive dismissal on a change of control. Stock options under the SOP and SunShare 2012 Plan, granted prior to 2012 but not yet exercisable, become immediately exercisable in the event of a change of control of Suncor. For stock option grants made beginning in 2012, the Board approved amendments to the SOP plan requiring a "double trigger" for immediate vesting.

PSUs and RSUs that were granted in 2010 and 2011 will vest in the event of a change of control subject to Suncor performance measured at the change of control date. For PSUs and RSUs granted beginning in 2012, the Board approved amendments to the plans requiring a "double trigger" to vest on a change of control, subject to Suncor performance measured at the change of control date.

Under the SOP, SunShare 2012 Plan, PSU Plan and RSU Plan, a change of control generally includes a transaction or series of transactions whereby any person or combination of persons, acting jointly or in concert, beneficially owns, directly or indirectly, or exercises control or direction over, 35% or more of the outstanding voting securities of Suncor or its successor.

NEOs with less than five years of executive service may become eligible to receive supplemental retirement payments under the SERP in the event of a change of control of Suncor, after the occurrence of certain specified corporate changes, or for certain executives, after a substantial decrease in such executive's responsibilities. In addition, Suncor has entered into certain trust arrangements for non-U.S. taxpayers to secure its obligations under the SERP upon a change in control of Suncor.

Mr. Jackman does not have a change of control clause in his termination contract. Pursuant to the terms of the SOP and PSU Plan, under a change of control, Mr. Jackman's 2010 and 2011 stock options would become immediately exercisable and Mr. Jackman's 2011 PSUs would vest subject to performance measurement at the change of control date.

Governance

The HR&CC annually reviews the status of termination agreement and change of control arrangements with Suncor's senior executives and periodically reviews current governance trends and market practices. Based on the Committee's review, amendments may be made to agreements for new participants.

Limited Appreciation Rights.    Executives, including the Named Executive Officers, key employees and certain Board members (who hold stock options under the ESP prior to grants to directors being discontinued after 2008), have LARs attached to all of their options issued under the SOP, and the closed ESP, Key Contributor Stock Option Plan ("SKCSO") and SunShare 2012 Plan (collectively, the "Suncor Plans") prior to January 1, 2013.

LARs represent a right attached to each option held by the LAR holder, exercisable upon completion of a change of control transaction, to receive a cash payment from Suncor under a pre-determined formula based on Suncor's share price, upon surrender of a related option.

LARs were generally issued annually at Suncor's discretion, have an 18-month term (unless a replacement LAR is issued, in which case the LAR continues in effect under the terms of the replacement LAR), and attach to all options granted under the Suncor Plans held by the holder during the term of the LAR. Upon the exercise or expiry of any option, the attached LAR is cancelled. Current LARs, applicable to grants in 2012 or prior, will expire on July 30, 2013.

Generally, LARs terminate and are of no further effect upon termination of employment, retirement, death or entitlement to long-term disability benefits. However, the Board has the discretion to permit the exercise of LARs in the manner and on such terms as it may authorize.

Looking Ahead to 2013

In 2012, following a review of market and governance practice, the HR&CC recommended to the Board that the LARs program be ended. The Board approved the HR&CC recommendation, discontinuing the practice of providing LARs for options granted under the Suncor Plans to executives, certain board members and key employees effective January 1, 2013.

INDEBTEDNESS OF DIRECTORS, EXECUTIVE OFFICERS AND SENIOR OFFICERS

None of the directors, executive officers or senior officers of Suncor, persons who served as directors, executive officers or senior officers at any time during 2012, or their respective associates, were at any time during the year, excluding routine indebtedness, indebted to Suncor or its subsidiaries, either in connection with the purchase of Suncor securities or otherwise.

SUMMARY OF INCENTIVE PLANS

The following table sets forth information in respect of securities authorized for issuance under our equity compensation plans as at December 31, 2012.

	Number of securities to be issued upon exercise of outstanding options (a)	Weighted-average exercise price of outstanding options ($)	Number of securities remaining available for future issuance under option plans (excluding securities reflected in column (a))
Equity compensation plans approved by security holders	42 210 485	37.98	7 020 057
Equity compensation plans not approved by security holders	5 113 659	41.25	—
Total	47 324 144	38.33	7 020 057

The numbers shown beside "Equity compensation plans approved by security holders" refer to options granted under the SOP, ESP, the PCSOP and the SunShare 2012 Plan. The numbers shown beside "Equity compensation plans not approved by security holders" refer to the SKCSO Plan.

Suncor Energy Stock Option Plan.    The Suncor Energy Inc. Stock Option Plan (previously defined as the "SOP") provides for the grant of options to purchase Suncor common shares, as well as the grant of SARs and LARs, to eligible employees of Suncor. Eligible employees are persons who provide services to Suncor or any of its subsidiaries or partnerships and for whom we are required by law to make income source withholdings.

Options entitle the holder to purchase shares at a price not less than the Market Value (as defined below) of the shares on the date of grant. Where SARs are granted on a stand alone basis, each SAR entitles the holder to receive, upon exercise, payment equal to the difference between the Market Value of a share on exercise and the Market Value of a common share on the date of grant. The options and SARs generally have a term of seven years. A tandem SAR, which may be granted with an option, entitles the holder to receive, upon exercise, a payment equal to the difference between the Market Value of a Suncor common share on exercise and the exercise price of the related option. The "Market Value" under the SOP for grants prior to January 1, 2013 was the simple average of the high and low prices at which common shares were traded in one or more board lots on the TSX on the day prior to the grant date or exercise date, as the case may be. Effective for option grants on or after January 1, 2013, the SOP has been amended such that "Market Value" means the simple average of the daily high and low prices at which common shares were traded in one or more board lots on the TSX over the five trading days immediately preceding the date of grant or exercise date, as the case may be. Shareholder approval for this amendment is not required under the SOP or pursuant to the rules of the TSX and therefore will not be sought.

Due to legislative changes in 2010 under the Income Tax Act (Canada), Suncor no longer grants SARs or tandem SARs to Canadian employees. In 2012, the Board approved discontinuing the practice of providing LARs for options granted under the SOP to executives, certain board members and key employees effective January 1, 2013. See "Termination Agreements and Change of Control Arrangements – Limited Appreciation Rights".

Performance Share Unit Plan.    PSUs may pay out at a value between 0% and 200% of the number of PSUs initially awarded contingent upon Suncor's performance relative to a peer group of companies over a three year period. The peer group is chosen based on size and business scope criteria approved by the HR&CC. The peer group for grants beginning in 2010 includes North American energy companies. The peer group is reviewed, adjusted as appropriate and approved by the HR&CC

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR        61

for each annual grant. The peer group for 2011 and 2012 PSU grants, along with other information about the peer group, is displayed below.

Peer	Revenue (1) (Billions) ($)	Market Capitalization (2) (Billions) ($)	Assets (1) (Billions) ($)

Median	20.5	32.0	45.4
75 th Percentile	175.4	68.1	101.4
Suncor	39.7	49.8	77.2
Suncor Percentile Ranking	72%	67%	72%

(1)

Percentile rank for Revenue is based on results reported for the nine months ended September 30, 2012 and for Assets is based on results reported as of September 30, 2012. Where applicable, results are converted to Canadian dollars based on the exchange rate on September 30, 2012.

(2)

Percentile rank for Market Capitalization is based on results reported as of December 31, 2012. Where applicable, values are converted to Canadian dollars based on the exchange rate on December 31, 2012.

Performance and the corresponding payout, if any, is measured by reference to Suncor's TSR relative to its peer group. The PSU Plan was amended in 2009 to provide for notional dividend reinvestment for awards granted after January 1, 2010.

Vesting for 2011 and 2012 grants of PSUs reward performance between the 25th and 100th percentiles of the peer group identified above as follows.

Percentage of PSUs Vesting at End of Three-Year Performance Period	Total Shareholder Return Performance Period Compared to Peer Group
Nil	Suncor TSR less than the 25th percentile of the peer group
50% to 200% (1)	Suncor TSR greater than or equal to the 25th percentile

(1)

Payout is based on actual interpolated position between the 25th percentile and the top performing company.

At the end of the three-year performance period, relative TSR is measured, the payout value is determined and, if applicable, subsequently paid to participants in cash. The final value is based on the number of vested PSUs multiplied by the common share price as determined under the PSU Plan provisions.

Since inception in 2004 the PSU vesting levels based on relative TSR performance have been as follows:

PSU Grant Year	Vesting Level
2004	100%
2005	100%
2006	Bottom Quartile / 0%
2007	Bottom Quartile / 0%
2008	Bottom Quartile / 0%
2009	112%
2010	111%

62        SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

PSUs do not count towards the assessment of executive share ownership levels for purposes of the share ownership guidelines. Upon payout, executives must use the cash payout, or other cash resources, to purchase Suncor common shares on the open market toward satisfying any unmet share ownership guidelines.

Looking Ahead to 2013

The HR&CC has approved an amendment to the PSU peer group following its 2012 annual review of the peer group companies. Effective for PSU grants made on or after January 1, 2013, the current peer group of 18 companies was reduced by three companies in line with peer group selection criteria.

The HR&CC also approved an amendment in the PSU vesting design in 2012. Effective for grants made on or after January 1, 2013, the PSU vesting level will be determined based on company grouping rank versus individual company percentile rank. The design change simplifies the way we measure performance and communication, while maintaining focus on performance.

Restricted Share Unit Plan.    The RSU Plan was established in January 2009 by the HR&CC. RSUs may be granted to key employees, senior managers and executives of Suncor as part of their competitive compensation in order to increase the retention aspects of the overall equity programs, as well as to further align participants with shareholder interests.

Each RSU is a right to a cash payment, equivalent in value to one Suncor common share based on the value of Suncor's average share price for the last 20 trading days of the restricted period. Awards under the RSU Plan are administered by the HR&CC. RSUs do not count towards the assessment of executive share ownership levels for purposes of the share ownership guidelines. The RSU Plan was amended in 2009 to provide for notional dividend reinvestment for grants after January 1, 2010.

Closed Plans.    The following table provides the key terms of the Suncor equity based plans that are closed to new grants.

2007	Petro-Canada Stock Appreciation Rights Plan (PCSAR) (8)	SAR	7 184 327	1/4 per yr over 4 yrs		7 years	No

(1)

All plans closed effective August 1, 2009, unless otherwise noted.

(2)

Option grants may include associated LARs.

(3)

Period of time from grant date until maximum expiry. Where no period indicated, maximum expiry is same as vesting schedule.

(4)

Includes two DSU plans. The first allowed eligible employees (as that term is defined in the plan) to elect to have their bonus payable in the next calendar year in DSUs. The second allowed eligible employees (as that term is defined in the plan) to receive DSUs at the discretion of the Management Resources and Compensation Committee of Petro-Canada.

(5)

Members (as that term is defined in the plan) could elect to have all or a portion of their annual board retainer and meeting fees in DSUs.

(6)

Share price targets under the SunShare 2012 Plan were achieved on May 12, 2008 and May 18, 2011. TSR target was not achieved. See footnote 7 for details on performance conditions.

(7)

The performance criteria include aggressive share price and TSR targets that align employee performance with shareholders' interests. Specifically, the performance criteria for 100% vesting of the SunShare 2012 options include two common share price targets and relative TSR performance in the top quartile among a peer group of companies. TSR is a measure of return on investment that includes both capital gains and dividends over the measurement period.

(8)

The PCSAR Plan provides a cash payment to participants equal to the appreciation in share price between the date the SARs were granted and the date the SARs are exercised. All SARs are non-transferable and non-assignable, and exercisable on terms determined by the HR&CC in its discretion at the time the SARs were granted. The exercise price per SAR cannot be less than the closing price of the common shares on the TSX on the day preceding the day the SAR was granted.

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR        63

Aggregate Potential Dilution.    The aggregate potential dilution of all issued, outstanding and authorized options under Suncor stock option plans was 3.0% at February 22, 2013. Suncor has no other equity compensation plans involving newly issued securities.

2012 Grant Rate (Run Rate): Stock options granted under the SOP in 2012 of 5,100,900 totalled less than 1% (approximately 0.3%) of shares outstanding at the end of 2012.

Additional Terms of Equity Compensation Plans:

•

The Suncor Plans contain an amendment provision providing that the Board may amend, suspend or terminate the plans as it, in its discretion, may determine, without shareholder approval except for those amendments specifically requiring shareholder approval as mandated by the respective plans including: (a) an increase in the number of securities reserved under the plans; (b) a reduction in an exercise price, or cancellation and reissue of options which benefits any option holder (other than as may be permitted by the TSX); (c) an amendment that extends the term of an award beyond its original expiry; (d) allowing awards granted under the plans to be transferable or assignable other than for normal estate settlement purposes; and (e) any amendment that increases the maximum number of options available for annual grants to non-employee directors.

•

The PCSOP contains an amendment provision providing that the HR&CC may amend the plan: (a) to make formal, minor or technical modifications to any of the provisions; (b) to change any of the provisions provided the change is not materially prejudicial to the interests of the option holders; or (c) to correct any ambiguity, defective provisions, error or omissions in the provisions of the plan provided that the rights of the option holders are not prejudiced by the correction. Subject to the obtaining of any required regulatory or other approvals, any other amendment is only effective after it has been approved by option holders, in accordance with the plan.

•

No one person or company is entitled to receive more than 5% of the issued and outstanding common shares.

•

All or any portion of an option or LAR granted under any of the Suncor Plans, or any entitlement to receive an option or LAR, is non-transferable and no assignment, encumbrance or transfer, whether voluntary, involuntary, by operation of law or otherwise, shall vest any interest or right in such option or LAR in any assignee or transferee. Immediately upon any assignment or transfer, the option or LAR shall terminate, be cancelled and of no further effect. Each option under the PCSOP is non-assignable and the rights of a holder under the PSCOP are non-transferable. However, an option and the right to exercise it may transfer to a participant's heirs and legal personal representative in death.

•

The exercise price of each option granted under the Suncor Plans and the PCSOP cannot be less than the fair market value of a common share at the time of grant.

•

Options granted prior to 2012 under the Suncor Plans, but not yet exercisable, become immediately exercisable in the event of a change of control of Suncor. The SOP was amended in 2012. We did not obtain shareholder approval for these amendments because they did not constitute an amendment under the plan or the rules of the TSX that required shareholder approval. Pursuant to the amendments, awards made under the SOP on or after January 1, 2012 will no longer automatically vest upon a change of control. Rather, upon the happening of a change of control, the SOP will require that awards that have been granted under the SOP on or after January 1, 2012 and that remain outstanding on the change of control be substituted with new awards on substantially the same terms and conditions. Provided the foregoing occurs, a holder's options will not vest upon or in connection with a change of control unless his or her employment is terminated within twelve months of the change of control (other than for cause), in which case the options will vest upon the holder's termination and shall expire three months following the termination date.

•

The Suncor Plans and the PCSOP provide for adjustments to be made for the effect of certain events, including but not limited to, subdivision, consolidation, reorganization or other events which necessitate adjustments to the options in proportion with adjustments made to all common shares.

•

The aggregate number of common shares which may be reserved for issuance under the SOP and all other security based compensation arrangements of Suncor, must not, within any one-year period be issued, or at any time under such arrangements be issuable, to insiders of Suncor (as defined in the TSX Company Manual) in an amount exceeding 10% of Suncor's total issued and outstanding securities.

•

Pursuant to the SOP, in the event of an employee's involuntary termination (other than for cause, death, permitted leave, retirement or in connection with a change of control) or voluntary termination of employment, unvested options expire immediately and vested options expire no later than three months from such termination. Vested options expire one year after termination of employment due to death and no later than three years after termination of employment due to retirement. If a holder is absent from work as a result of a permitted leave, the holder's options shall continue to vest for a period of twenty-four months from the date of commencement of the leave and the right to exercise such holder's options shall terminate no later than the expiration of twelve months from the date that is twenty-four months from the date of commencement of the leave. If the holder has not returned to active service prior to the expiration of twenty-four months

64        SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

from the date of commencement of the permitted leave then the holder's options which were not exercisable twenty-four months from the date of commencement of such leave shall immediately terminate. In the event of involuntary termination for cause, all options expire on the date of such termination.

•

Pursuant to the ESP and the SKCSO, in the event of an employee's involuntary or voluntary termination of employment, unvested options expire immediately and vested options expire no later than six months from such termination. Vested options expire no later than one year after termination of employment due to death and no later than three years after termination of employment due to retirement. If a holder becomes entitled to disability benefits, the holder's options shall continue to vest for a period of twenty-four months from the date of entitlement to disability benefits and the right to exercise such holder's options shall terminate no later than the expiration of twelve months from the date that is twenty-four months from the date of commencement of such entitlement. If the holder has not returned to active service prior to the expiration of twenty-four months from entitlement to disability benefits then the holder's options which were not exercisable twenty-four months from the date of entitlement shall immediately terminate.

•

Pursuant to the SunShare 2012 Plan, all unvested options are cancelled on cessation of employment for any reason other than death, retirement or disability. Vested options expire in these circumstances six months from cessation of employment, unless the employee is terminated for cause in which case the vested options also expire immediately. Upon termination of employment due to death, unvested options expire one year from the employee's death and 18 months from the employee's death if they vest during the first year after the employee's death.

•

Pursuant to the PCSOP, unless otherwise determined at the time of grant, in the event of: (a) the death of an option holder, all options shall immediately vest with one year to exercise or until the normal expiry date if earlier; (b) voluntary retirement of an option holder, all options held shall immediately vest upon the date of retirement and may be exercised after vesting for up to three years after retirement or until the normal expiry date, if earlier; (c) the termination without cause of the option holder's employment, options vested on the effective date of the termination may be exercised within the earlier of 90 days of the effective date of termination or the normal expiry date and all other options expire immediately; and (d) termination with cause of the option holder's employment or voluntary resignation (other than at retirement), all options expire immediately.

DIRECTORS' AND OFFICERS' INSURANCE

Under policies purchased by Suncor, approximately US$150 million of insurance is in effect for the directors and officers of Suncor against liability for any actual or alleged error, misstatement, misleading statement, act, omission, neglect or breach of duty in discharging their duties, individually or collectively. Suncor is also insured under these policies in the event it is permitted or required by law to indemnify individual directors and officers.

The policies are subject to certain exclusions, and provide for a corporate deductible of US$10 million in circumstances where Suncor indemnifies individual directors and officers. If Suncor is unable by law to indemnify individual directors and officers, including in an event of insolvency, there is no deductible. In 2012, Suncor paid premiums of approximately US$1.4 million for directors and officers insurance for the 12-month period ending July 1, 2012.

CORPORATE GOVERNANCE

The Board is committed to maintaining high standards of corporate governance, and regularly reviews and updates its corporate governance systems in light of changing practices, expectations and legal requirements.

Suncor is a Canadian reporting issuer. Our common shares are listed on both the TSX and the New York Stock Exchange ("NYSE"). Accordingly, our corporate governance practices reflect applicable rules and guidelines adopted by the Canadian Securities Administrators (the "Canadian Requirements") and the U.S. Securities and Exchange Commission ("SEC"), including applicable rules adopted by the SEC to give effect to the provisions of the Sarbanes Oxley Act of 2002 (collectively, the "SEC Requirements"). NYSE corporate governance requirements are generally not applicable to non-U.S. companies. However, Suncor has reviewed its practices against the requirements of the NYSE applicable to U.S. domestic companies ("NYSE Standards"). Based on that review, Suncor's corporate governance practices in 2011 and 2012 did not differ from the NYSE Standards in any significant respect, with the exceptions described in Schedule C attached to this management proxy circular under the heading, "Compliance with NYSE Standards".

Suncor's Statement of Corporate Governance Practices ("Statement") this year is based on the Canadian Requirements, as set out in National Policy 58-201 Corporate Governance Guidelines and National Instrument 58-101 Disclosure of Corporate Governance Practices. This Statement has been approved by the Board, on the recommendation of its Governance Committee. Suncor's Statement can be found in Schedule C attached to this management proxy circular.

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR B-2

SCHEDULE C: CORPORATE GOVERNANCE SUMMARY

THROUGHOUT THIS SUMMARY, THERE ARE REFERENCES TO INFORMATION AVAILABLE ON THE SUNCOR ENERGY INC. ("SUNCOR" OR THE "CORPORATION") WEB SITE ⁽¹⁾. ALL SUCH INFORMATION IS AVAILABLE AT WWW.SUNCOR.COM UNDER THE "ABOUT US-GOVERNANCE" TAB. IN ADDITION, SHAREHOLDERS MAY REQUEST PRINTED COPIES OF THESE MATERIALS BY CONTACTING SUNCOR AT THE ADDRESS ON THE BACK OF THIS CIRCULAR, BY CALLING 1-800-558-9071 OR BY EMAIL REQUEST TO INFO@SUNCOR.COM.

"The Board is comprised of a majority of independent directors (11 of 12 members (91.7%)). All of the members of the committees of the Board are independent. Suncor's independent directors meet in camera at the beginning and end of each board and committee meeting without management present."
Board of Directors – Composition and IndependenceThe cornerstone of Suncor's governance system is its board of directors (the "Board" or "Board of Directors"), whose duty is to supervise the management of Suncor's business and affairs. The composition of the Board and its independence are important elements of this system. Steven W. Williams, Suncor's President and Chief Executive Officer ("CEO") is the only member of the Board who is not independent. Following the annual general meeting and assuming that all directors are elected as contemplated in the Circular, 11 of 12 members (91.7%) of the Board will be independent directors. A short biography of each Suncor director standing for election can be found starting on page 8 of the Circular.

Each of the Governance, Audit and Human Resources and Compensation Committee ("HR&CC") are required to be and are comprised entirely of independent directors. In addition, the Environment, Health, Safety and Sustainable Development ("EHS&SD") Committee is comprised entirely of independent directors.

Suncor's independent directors meet in-camera at the beginning and end of each Board meeting without management present. Mr. Williams, as a member of

management and the only Suncor director who is not independent, does not participate in these sessions. The sessions are presided over by John T. Ferguson, who has been Suncor's independent chairman since April 2007. The Board's committees also hold in-camera sessions without management present immediately before and following each of their meetings. These sessions are presided over by the independent chairs of the respective committees. Any issues addressed at the in-camera meetings requiring action on behalf of, or communication to management, are communicated to management by the independent chair or another independent director.

The Board has developed and approved written position descriptions for the Board chairman and Board committee chairs, each of which are available on Suncor's website. The position description for Suncor's chairman of the Board is also set out in Schedule D attached to the Circular. The position descriptions for the Board chairman and Board committee chairs supplement the Terms of Reference, as defined below, and are reviewed annually by the Governance Committee. Any changes to the position descriptions are recommended by the Governance Committee to the full Board.

The Board reviews the independence of its members annually. The Board has adopted independence criteria for assessing the independence of directors including additional requirements applicable to members of the Audit Committee. The Board's independence policy and criteria include a description of certain relationships that operate as a complete bar to independence. Suncor's independence criteria are consistent with the Canadian Requirements and the SEC Requirements (each defined on page 65 of the Circular). The independence criteria are set out in Schedule E attached to the Circular.

In applying the independence criteria, the Board reviews and analyzes the existence, materiality and effect of any relationships between Suncor and each of its directors, either directly, through a family member or as a partner, shareholder or officer of another organization that has a relationship with Suncor and determines in each case whether the relationships could, or could reasonably be perceived to, materially interfere with the director's ability to act independently of management.

C-1 SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

Some of Suncor's directors sit on the boards of other public companies, the particulars of which are set out in the biographies on pages 8 to 13 of the Circular. No members of the Board sit together on the board of any other entity.

Some members of the Board are involved with companies with which Suncor has business relationships. The Board has reviewed these relationships on a case-by-case basis against the independence criteria and has determined that none of these relationships impair the independence of the individual directors, as the directors do not serve as employees or executives of these other companies, their respective remuneration from these directorships is not personally material to them nor is it dependent on or variable with the nature or extent of the business relationship with Suncor and they are not personally involved in negotiating, managing, administering or approving contracts between Suncor and the other entities on whose boards they serve. The Board's conflict of interest policy, described in detail below, precludes these directors from voting with respect to any of these arrangements, should they be considered by the Board. In the event there is any material discussion of these arrangements or any arrangements involving competitors of these entities by the Board, these directors are expected to declare such interest and absent themselves from the boardroom during those discussions.

"The Board has adopted terms of reference, which include a board mandate."
Terms of ReferenceThe Board has adopted terms of reference (the "Terms of Reference"), which serve as the charter of the Board and which are reviewed by the Board at least annually. The Terms of Reference include a general overview of the Board's role in Suncor's governance, a statement of key guidelines and policies applicable to the Board and its committees and a mandate that describes its major

responsibilities, goals and duties. These major responsibilities, goals and duties range from specific matters, such as the declaration of dividends that by law must be exercised by the Board, to its general role to determine, in broad terms, the purposes, goals, activities and general characteristics of Suncor and its business. The Terms of Reference provide that the Board is responsible for the selection, monitoring and evaluation of executive management and for overseeing the ways in which Suncor's business and affairs are managed, thereby assuming responsibility for the stewardship of Suncor. The full text of the Terms of Reference is set out in Schedule F attached to the Circular.

The Board of Directors discharges its responsibilities through preparation for and attendance at, regularly scheduled meetings and through its four standing committees, namely the Governance Committee, the Audit Committee, the EHS&SD Committee and the HR&CC. Each committee has a written mandate that is reviewed annually by such committee. In considering the appointment of members to the committees, the Board ensures that each committee includes directors of diverse background and at least one director with significant expertise relevant to the committee's roles.

Each of these committees is comprised solely of independent directors and, except where otherwise specified in the Terms of Reference, or in Suncor's by-laws, each committee has the power to determine its own rules of procedure. Subject to limited exceptions, these committees generally do not have decision making authority; rather, they convey their findings and recommendations on matters falling within their respective mandates to the full Board of Directors.

The committees also have the authority to conduct any independent investigations into matters which fall within the scope of their responsibilities and may engage external advisors (as may the full Board or an individual director), at Suncor's expense, to assist them in fulfilling their mandate. For a brief summary of the key functions, roles and responsibilities of Board committees, see "Board Committees" on page 6 of this Schedule.

The Board of Directors delegates day-to-day management of Suncor's business to Suncor's CEO and other members of senior management. The Board, through the CEO, sets standards of conduct, including Suncor's general moral and ethical tone, compliance with applicable laws, standards for financial practices and reporting, qualitative standards for operations and products and other standards that reflect the views of the Board as to the conduct of the business of Suncor. A management control process policy, adopted by the Board, defines and sets limits on the authority delegated to management.

The Board has developed and approved a written position description for the CEO, which includes a general description of the role as well as specific accountabilities in the areas of strategic planning, financial results, leadership, safety, government, environment and social relations and management's relationship with the Board. A copy of the CEO position description is available on Suncor's website.

The following is a description of some key duties of the Board as set out in the Terms of Reference. The following description is not exhaustive. For more information, please refer to the "Board Committees" section on page 6 of this Schedule, the Terms of Reference set out in Schedule F attached to this Circular and the mandates of the Board committees, available on Suncor's web site.

Ethics.    The Terms of Reference explicitly recognize that the Board, through the CEO, sets Suncor's standards of conduct, including Suncor's general moral and ethical tone and standards for compliance with applicable laws. The Terms of Reference also state that the Board should be satisfied that the CEO is creating and fostering a culture of integrity within Suncor. The Board plays an active role in this area through its oversight of Suncor's standards of business conduct code (the "Code") and

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR C-2

compliance program (see "Ethical Business Conduct" on page 8 of this Schedule) and through its assessment and evaluation of the performance of the CEO. The CEO's position description includes accountability for setting a high ethical tone for the organization as a whole and fostering a culture of integrity throughout the organization.

Strategic Planning.    One of the Board's major duties is to review, with management, Suncor's mission, objectives and goals and the strategies for achieving them. The Board is responsible for ensuring Suncor has an effective strategic planning process and for annually approving the capital budget and the strategies reflected in Suncor's long-range plan. A Board meeting principally devoted to corporate strategy is held annually. The Governance Committee assists the Board by annually assessing Suncor's planning and budgeting processes and by acting as an effective sounding board for management on key strategic initiatives. It also works with management to design the annual strategy meeting and assesses the effectiveness of this meeting. The Board is continually provided with updates on the human, technological and capital resources required to implement Suncor's strategies and any regulatory, environmental, social, cultural or governmental constraints that may impact Suncor carrying out its business objectives.

Risk Oversight.    One of the major responsibilities of the Board is to oversee the identification of the principal risks of Suncor's business and ensure there are systems in place to effectively identify, monitor and manage them. At Suncor, a principal risk is generally defined as an exposure that has potential to materially impact Suncor's ability to meet or support its strategic objectives.

SUNCOR HAS ADOPTED TOOLS, INCLUDING AN ENTERPRISE RISK MANAGEMENT SYSTEM, OPERATIONAL EXCELLENCE MANAGEMENT SYSTEM AND TRADING RISK MANAGEMENT POLICY, TO IDENTIFY AND MANAGE RISK.

"The board undertakes an annual principal risk review and monitors risk and in-place management of risk throughout the year."
As part of its risk management governance system, the Board undertakes an annual principal risk review which involves the identification and assessment of the principal risks of Suncor's business and a review of the risk management strategies and systems being employed by management to identify, monitor and manage these risks. The Board has also overseen the development by management of Suncor's Enterprise Risk Management Program (the "ERM Program"). In accordance with the ERM Program, senior management undertakes an

entity-wide process to identify, classify, assess and report on Suncor's principal risks and management strategies to address risk, which is reviewed by the Board in its annual principal risk review, and the governance of which is reviewed by the Audit Committee semi-annually. The Audit Committee independently verifies management's assessment of risk by reviewing and approving the appointment of the general manager of Suncor's Internal Audit and Enterprise Risk Management functions, who reports directly to the Audit Committee regarding Enterprise Risk Management's evaluation of the effectiveness of Suncor's risk management process. In addition, members of the Board are encouraged to ask questions of management at Board and committee meetings, as well as throughout the year, to ensure that risks are appropriately identified, monitored and managed. The high level of engagement of Board members, as well as their extensive experience, contributes to the Board's risk oversight role. For a detailed explanation of the risks applicable to Suncor and its businesses, see "Risk Factors" in Suncor's Annual Information Form dated March 1, 2013, filed at www.sedar.com.

In its risk oversight role, the Board has overseen the development by management of Suncor's Operational Excellence Management System ("OEMS"), which is an overarching framework for Suncor to manage all aspects of operational risk. OEMS consists of a series of elements, with corresponding implementation guidelines, that organize and link into one platform all key standards, systems and processes required to manage operational risks and environmental impacts, and deliver safe, reliable operations.

The committees of the Board also play a significant risk oversight role. As mentioned above, the Audit Committee conducts periodic reviews to monitor Suncor's principal risks and the management of same and ensures such principal risks are reflected in the mandates of the Board and its committees. As part of this review, each risk is mapped to a Board committee or the full Board as appropriate, for oversight. The Audit Committee, for example, reviews significant physical security management, IT security or business recovery risks and strategies to address such risks. In addition, the Audit Committee reviews financial risk management issues, programs and policies, including cash management, insurance and trading activities. In this role, the Audit Committee oversaw Suncor's adoption of a Trading Risk Management Policy (the "Trading Policy") to address commodity trading risk. The Trading Policy requires all such activities to occur in the group responsible for trading, so that trading risks can be properly monitored, controlled and reported. The Board has set the trading commodities, trading term limits, value at risk limits and stop loss limits under the Trading Policy and any changes to the foregoing require Board approval. The Board reviews and monitors Suncor's compliance with the Trading Policy through the Audit Committee, which receives a quarterly report that summarizes Suncor's trading activities and provides an assessment of Suncor's financial exposure risk from these activities.

C-3 SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

Another committee playing a significant risk oversight role is the EHS&SD Committee. The EHS&SD Committee assists the Board in matters pertaining to the integrity of Suncor's physical assets, by monitoring the adequacy of Suncor's internal controls as they relate to operational risks of its physical assets and matters of environment, health, safety and sustainable development. In fulfilling this role, the EHS&SD Committee reviews the results of evaluations of internal controls by the Operations Integrity Audit function as well as progress reports on the implementation of OEMS by Suncor, and reports to the Board of Directors on these matters. In addition, the EHS&SD Committee reviews and approves the appointment or termination of the Director, Operations Integrity Audit, the engagement (including the audit scope, approach, performance and fees) or termination of the external Operations Integrity Auditors and organizational structure of the Operations Integrity Audit department. The EHS&SD Committee also reviews the Operations Integrity Audit charter and its annual audit plans and activities.

The Governance Committee assists the Board by reviewing and assessing emerging risk areas that do not fall under the mandate of another Board committee. In addition, the Governance Committee oversees the Board's governance oversight of Suncor's reputation risk by conducting periodic reviews to ensure the key elements of Suncor's reputation risk are appropriately identified and reflected in the mandate of the Board and its committees, and to exercise stewardship over residual reputation risks that are not addressed by another Board committee.

The HR&CC likewise assists the Board by ensuring executive compensation related reputational risks are understood and considered, and by reviewing compensation programs to ensure they do not encourage excessive or inappropriate risk taking. The HR&CC also reviews and approves any material incentive plans and amendments to existing incentive plans to, amongst other things, examine their risk implications.

"Effective succession planning has long been a focus of the board. The HR&CC reviews the succession planning process and results for executive management annually."
Succession Planning and Monitoring/Evaluating Senior Management.The Board ensures the continuity of executive management by appointing a CEO and overseeing succession planning. The HR&CC is specifically mandated to assist the Board in this regard, by ensuring that appropriate executive succession planning and performance evaluation programs and processes (including development and career planning) are in place and operating effectively for executives. The HR&CC also reviews significant changes to the organization's structure as they arise and their impact on executive roles.

The HR&CC undertakes an annual review of the succession planning process and results for executive management and reports to the Board on these matters. As part of this annual process, the CEO, supported by the Senior Vice President, Human Resources, reviews candidates for the CEO and other executive management positions with the

HR&CC. In its July 2012 meeting, the HR&CC reviewed Suncor's succession planning process and its succession plans for Suncor's executive management team, and subsequently reported to the Board that they found that management has a strong process in place for identifying high potential employees, and the creation of development plans to prepare such individuals for higher level jobs.

The Board also reviews Suncor's processes for successors for its vice presidents, employees who directly report to its vice presidents and managers. Successors are identified using a formalized and consistent process which rigorously assesses leadership potential across Suncor, using specific and clear criteria, including employees' performance, aspirations, engagement, agility, experience and capabilities. To support the development of future leaders, Suncor offers employees multi-day experiences focused on leadership skills and managing resources to support leadership competence as a core organizational capability.

The Board encourages the CEO to expose the Board to Suncor's executives and high potential employees, both for succession planning and career development and to provide the Board with a broader perspective and context on issues relevant to Suncor. Directors are provided with opportunities to meet with Suncor employees through attendance at events hosted by Suncor, such as Suncor's President's Operational Excellence Awards, or when they visit Suncor's facilities (see "Orientation and Continuing Education" on page 7 of this Schedule).

The HR&CC assists the Board in monitoring the performance of the CEO by conducting an annual review of the CEO's performance against predetermined goals and criteria (including the goal of succession planning) and reporting to the Board as well as recommending to the Board the total annual compensation of the CEO (see "Compensation Discussion and Analysis" beginning on page 25 of the Circular). The HR&CC also reviews with the CEO the performance of his direct reports and recommendations for their total compensation.

Communication/Disclosure Policy and Stakeholder Feedback.    Suncor has a disclosure policy called "Communications to the Public" that establishes guidelines and standards for Suncor's communications with shareholders, investment analysts,

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR C-4

other stakeholders and the public generally. This policy includes measures to avoid selective disclosure of material information, identifies designated Suncor spokespersons and establishes internal review processes for key public communications. The Code (see "Ethical Business Conduct" on page 8 of this Schedule) addresses Suncor's obligations for continuous and timely disclosure of material information and sets standards requiring directors, officers, employees and contractors trading in Suncor shares and other securities to comply with applicable law.

Suncor has disclosure controls and procedures designed to ensure that material information relating to Suncor is made known to our CEO and Chief Financial Officer ("CFO"). Suncor has a Disclosure Committee, chaired by the Vice President and Controller, and has designed and implemented due diligence procedures to support the financial reporting process and the certification of our financial reports by the CEO and CFO.

Suncor interprets its operations for its shareholders and other stakeholders through a variety of channels, including its periodic financial reports, securities filings, news releases, sustainability and climate change reports, webcasts, external website, briefing sessions and group meetings. Suncor encourages and seeks stakeholder feedback through various channels including corporate communications and investor relations programs and through participation in the regulatory process. The Board, either directly or through the activities of a designated Board committee, reviews and approves all quarterly and annual financial statements and related management's discussion and analysis ("MD&A"), management proxy circulars, annual information forms/Form 40-F and press releases containing significant new financial information, among others.

The Board of Directors is specifically mandated to ensure systems are in place for communication with Suncor's shareholders and other stakeholders and that these systems are appropriately resourced. Suncor currently maintains a toll-free phone number as well as email and regular mail addresses for stakeholder feedback and questions. In addition, Suncor encourages shareholders to attend Suncor's annual meeting. The annual meeting provides a valuable opportunity to hear directly from Suncor's management about the results of Suncor's business and operations, as well as its strategic plans. Members of the Board are in attendance at annual meetings and the chairman of the Board and the chair of each Board committee are available to answer questions as appropriate.

"The Board has adopted a shareholder communication and engagement policy."
The Board recognizes that it is also important for the Board to communicate with shareholders, including organizations that represent or advise shareholders on matters of governance (collectively, "Interested Parties") and to that end, has adopted a Board of Directors' Shareholder Communication and Engagement Policy

(the "Engagement Policy"). In accordance with the Engagement Policy, Interested Parties may communicate to the Board in writing to express their views on matters that are important to them, by addressing their correspondence to the Board in care of the Corporate Secretary at the address set forth on the back page of the Circular or via email at: info@suncor.com, subject line: Attention: [Chairman of the Board / Chair of [Insert Board Committee Name]] c/o Corporate Secretary. The Board has determined that questions or concerns related to the Board and senior management succession process, executive and Board compensation, Board level corporate governance and other matters that are within the scope of the Board's supervisory and oversight duties, as set out in its Terms of Reference, may appropriately be addressed to and by, the Board. In addition, the Engagement Policy recognizes that in certain circumstances it may be appropriate for Board members, generally through the chairman of the Board or the chair of a committee, to meet with an Interested Party, and sets out criteria to be considered if the Board receives a meeting request and terms applicable to the conduct of any such meeting.

Expectations and Responsibilities of Directors.    The Terms of Reference, supplemented by a Board approved accountability statement for directors (the "Accountability Statement"), which is available on Suncor's web site, identifies the key expectations placed on Board members. Directors are expected to review meeting materials in advance of meetings to encourage and facilitate discussion and questions. Board meeting dates are established well in advance and directors are expected to be prepared for and attend all meetings absent extenuating circumstances. Directors' attendance records for meetings held in 2012 are set out on page 10 of this Schedule.

Directors must devote sufficient time and energy to their role as Suncor director to effectively discharge their duties to Suncor and the Board. Pursuant to the Terms of Reference, Audit Committee members must not be members of the audit committees of more than two other public companies, unless the Board determines that simultaneous service on a greater number of audit committees would not impair the member's ability to effectively serve on Suncor's Audit Committee.

Internal Controls.    The Board of Directors is specifically mandated to ensure processes are in place to monitor and maintain the integrity of Suncor's internal controls and management information systems. The Audit Committee assists the Board in this regard and monitors the effectiveness and integrity of Suncor's financial reporting, management information, internal controls and Suncor's Internal Audit function (excluding operations integrity audit matters, which are specifically within the mandate of the EHS&SD Committee ⁽²⁾).

References throughout this Schedule to "Internal Audit" in relation to the Audit Committee do not include the operations integrity audit department.

C-5 SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

The Audit Committee exercises general oversight over the Internal Audit function by reviewing the plans, activities, organizational structure, qualifications and performance of the Internal Auditors. The appointment or termination of the general manager in charge of Internal Audit is reviewed and approved by the Audit Committee. This officer has a direct reporting relationship with the committee and meets with it, in the absence of other members of management, at least quarterly. The Audit Committee also reviews and recommends appointees to the office of the CFO.

Board Committees

In addition to the responsibilities described elsewhere in this Schedule, the following provides a brief summary of the key functions, roles and responsibilities of Suncor's Board committees. The complete text of the mandate of each Board committee is available on Suncor's web site.

Governance Committee.    The Governance Committee assists the Board in two main areas: corporate governance; and corporate strategy. In its governance role, the Governance Committee is mandated to determine Suncor's overall approach to governance issues and key corporate governance principles.

"The Governance Committee closely monitors emerging best practices in governance." In doing so, it closely monitors emerging best practices in governance. In addition, the Corporate Secretary, or her delegate, attends seminars, conferences and meetings on governance and updates the committee on developing trends and practices. In 2012, workshops hosted by the Canadian Society of Corporate Secretaries and Canadian and U.S. law firms were attended. In addition, Suncor

participated in a group comprised of corporate secretaries from large issuers in which members consult with one another and share ideas about governance issues. Suncor also reviews recommendations of governance and shareholder advisory organizations and participates in benchmarking studies undertaken by such organizations to assess its governance practices in relation to those of other issuers in a wide range of geographies and industries. The Corporation's legal function also monitors changes in law, administrative policy and stock exchange requirements relating to governance, and provides updates to the Governance Committee. The committee also reviews matters pertaining to Suncor's values, beliefs and standards of ethical conduct and Suncor's corporate reputation and assists the Board in its strategy role (see "Strategic Planning", under the heading "Terms of Reference" on page 3 of this Schedule).

The Governance Committee reviews and reports to the Board on directors' compensation issues. The Governance Committee has developed, in consultation with the HR&CC and outside advisors, guidelines for director compensation based on, among other factors, directors' roles and responsibilities and an analysis of the competitive position of Suncor's director compensation program. The Governance Committee annually reviews the competitiveness and form of Board compensation and makes recommendations to the full Board on Board compensation and share ownership guidelines for directors. The Board has set director compensation based upon recommendations from this committee.

Audit Committee.    The Audit Committee assists the Board in matters relating to Suncor's external auditors and the external audit process, oil and natural gas reserves reporting, financial reporting and public communication, risk management, security and certain other key financial matters. The Audit Committee also assists the Board in matters relating to Suncor's internal controls and the Internal Audit function (see "Internal Controls", under the heading "Terms of Reference" on page 5 of this Schedule).

The Audit Committee plays a key role in relation to Suncor's external auditors. It initiates and approves their engagement (including fees) or termination, subject to shareholder approval, and monitors and reviews their independence, effectiveness, performance and quality control processes and procedures.

The Audit Committee reviews and approves, with management and external auditors, significant financial reporting issues, the conduct and results of the annual audit and significant finance, accounting and disclosure policies and other financial matters. The Audit Committee also plays a key role in financial reporting, by reviewing Suncor's core disclosure documents, being its annual and interim financial statements, MD&A, annual information form and Form 40-F. The committee approves interim financial statements and interim MD&A and makes recommendations to the Board with respect to approval of the annual disclosure documents.

The Audit Committee also plays a key oversight role in the evaluation and reporting of Suncor's oil and natural gas reserves. This includes review of Suncor's procedures relating to reporting and disclosure, as well as those for providing information to Suncor's independent reserves evaluator. The Audit Committee approves the appointment and terms of engagement (including fees) of the reserves evaluator, including their qualifications and independence and any changes in their appointment. Suncor's reserves data and report of the reserves evaluator are annually reviewed by the Audit Committee prior to approval by the full Board of Directors.

The Audit Committee reviews Suncor's policies and practices with respect to cash management, financial derivatives, financing, credit, insurance, taxation, commodities trading and related matters. It also reviews the assets, financial performance, funding

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR C-6

and investment strategy of Suncor's registered pension plan. The Audit Committee oversees generally the Board's risk management governance model (see "Risk Oversight", under the heading "Terms of Reference" on page 3 of this Schedule) and also monitors Suncor's business conduct code compliance program (see "Ethical Business Conduct" on page 8 of this Schedule).

Members of the Audit Committee are required to be financially literate. In addition, at least one member of the Audit Committee must be determined by the Board to be an "audit committee financial expert". The Board has determined Mr. O'Brien and Mr. D'Alessandro, members of the Audit Committee and independent directors, to be such experts. The criteria for assessing the financial literacy of Audit Committee members and whether they qualify as an "audit committee financial expert", are set out in the Terms of Reference in Schedule F attached to the Circular.

For additional information about Suncor's Audit Committee, including the Audit Committee Mandate and Pre-approval Policies and Procedures, see "Audit Committee Information" in Suncor's Annual Information Form dated March 1, 2013, filed at www.sedar.com.

Environment, Health, Safety and Sustainable Development Committee.    The EHS&SD Committee reviews the effectiveness with which Suncor meets its obligations and achieves its objectives pertaining to the environment, health, safety and sustainable development. This includes the effectiveness with which management establishes and maintains appropriate EHS&SD policies. The EHS&SD Committee also monitors management's performance and emerging trends and issues in these areas. In fulfilling its role, the EHS&SD Committee reviews quarterly, annual and other management stewardship reports as well as the findings of significant external and internal environmental, health and safety investigations, assessments, reviews and audits. Suncor's periodic sustainability report, a detailed public disclosure document that includes reporting on Suncor's EHS&SD progress, plans and performance objectives, is also reviewed by the EHS&SD Committee.

The EHS&SD Committee also assists the Board in matters pertaining to the integrity of Suncor's physical assets, by monitoring the adequacy of Suncor's internal controls as they relate to operational risks of its physical assets and matters of environment, health, safety and sustainable development (see "Risk Oversight", under the heading "Terms of Reference" on page 3 of this Schedule).

Human Resources and Compensation Committee.    The HR&CC assists the Board by annually reviewing the performance of the CEO and recommending his total compensation to the full Board. The corporate objectives for which the CEO is responsible include a combination of corporate goals and personal goals, set annually by the Board of Directors in consultation with the HR&CC and the chairman of the Board. The HR&CC annually reviews the CEO's performance against these objectives and against the key accountabilities of his position, as set out in the CEO's position description. The HR&CC reports its assessment to the full Board which ultimately approves CEO compensation.

The HR&CC also reviews annually the CEO's evaluation of the other senior executives within the organization and his recommendation for their total compensation. No member of the HR&CC is currently a chief executive officer of any other public issuer.

For more information about the HR&CC and the process and criteria for determining the CEO's total compensation, see "Compensation Discussion and Analysis" on page 25 of the Circular. See also "Succession Planning and Monitoring/Evaluating Senior Management", under the heading "Terms of Reference" on page 4 of this Schedule.

Orientation and Continuing Education

AT LEAST ONCE ANNUALLY, THE BOARD MEETS AT A SUNCOR LOCATION OUTSIDE OF CALGARY SO THAT IT CAN LEARN ABOUT SUNCOR'S OPERATIONS AND COMMUNITIES IN WHICH THEY ARE CARRIED OUT. THE BOARD HAS A STRATEGIC EDUCATION PROGRAM AND CONTINUING EDUCATION POLICY IN PLACE, BOTH OF WHICH WERE EFFECTIVELY UTILIZED IN 2012.

Each new member of the Board participates in a formal orientation program. The orientation program includes in-person meetings with senior management on key legal, environmental, business, financial and operational topics central to Suncor's business and operations and a tour at the sites of some of Suncor's principal operations. The orientation program also focuses on the role of the Board, its committees and its directors and the nature and operation of Suncor's business.

A directors' handbook, containing information about the Board and Suncor, including Suncor's core governance documents, is presented to each director upon joining the Board. The handbook is continuously updated and is available for viewing by directors through a dedicated and secure directors' portal.

Presentations and tours at the sites of Suncor's principal operations are provided to directors on a periodic basis, often in conjunction with Board meetings, for the purpose of directly acquainting directors with Suncor's operations and the communities in which they are located. The presentations and tours also serve as opportunities for directors to meet and familiarize themselves with senior executives and high potential employees.

C-7 SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

The Governance Committee maintains the Board's strategic education program. In conjunction with Board meetings, management presents focused information to directors on topics pertinent to Suncor's business, including the impact of significant new laws or changes to existing laws and opportunities presented by new technologies. In an annual survey, directors are asked to suggest topics of interest for future information sessions and topics are chosen annually for speakers and / or presentations from internal or external sources.

The Board's Director Continuing Education Policy also encourages directors to enroll in courses and programs that enhance and supplement their knowledge and skills in areas relevant to their role on the Board, with the approval of the chairman of the Board or chair of the Governance Committee. Through this program, Suncor's directors have taken courses in such diverse topics as reserves evaluation, financial accounting and corporate governance, including the programs attended in 2012 by Ms. McCaw and Mr. Benson noted in the table below.

During 2012, the Board, its committees and individual directors participated in presentations and received educational information on a variety of topics, including those set out in the table below.

"Suncor has adopted a business conduct code, supported by detailed guidance and standards and a code compliance program."
Ethical Business ConductSound, ethical business practices are fundamental to Suncor's business. The Code, which applies to Suncor's directors, officers, employees and contract workers, requires strict compliance with legal requirements and sets Suncor's standards for the ethical conduct of our business. Topics addressed in the Code include competition, conflict of interest and the protection and proper use of corporate assets and opportunities, confidentiality, disclosure of material information, trading in shares and securities, communications to the public, improper payments,

harassment, fair dealing in trade relations and accounting, reporting and business control. The Code is supported by detailed policy guidance and standards and a Code compliance program, under which every Suncor director, officer, employee and

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR C-8

contract worker is required annually to read a summary of the Code and affirm that he or she has reviewed the summary, affirm that he or she understands the requirements of the Code and provide confirmation of his or her compliance with the Code during the preceding year. The summary provided includes a message from the President and CEO, emphasizing Suncor's values and making it clear that all representatives of Suncor are expected to conduct daily business in a safe, fair, honest, respectful and ethical manner.

The Board exercises stewardship over the Code in several respects. Suncor's Internal Auditors audit the compliance program annually and the general manager of Internal Audit, who has direct reporting relationships with the Audit Committee, reports on compliance to that committee.

Moreover, at least once annually, the Code is reviewed and if appropriate, updated. Management reports to the Governance Committee annually on this process and any changes are reviewed by the Governance Committee. Any waivers of Code requirements for Suncor's executive officers or members of the Board of Directors must be approved by the Board of Directors or appropriate committee thereof and disclosed. No such waivers were granted in 2012.

Suncor encourages employees to raise ethical concerns with Suncor management and Suncor's legal, corporate security, human resources and Internal Audit departments, without fear of retaliation. In addition, Suncor's "Integrity Hotline" provides a means for Suncor employees to raise issues of concern anonymously, with a third party service provider. The Integrity Hotline is available 24 hours a day, seven days a week. Any issues of a serious nature are investigated by Suncor's Internal Auditors or security staff. The Audit Committee receives regular updates on activities relating to the Integrity Hotline.

Suncor provides additional specialized training for employees for matters governed by the Code, where it is determined such training would be beneficial. For example, all employees directly involved with Suncor's international and offshore operations are required to attend focused workshops, which address, among other items, compliance with sanctions and anti-bribery and anti-corruption legislation and best practices for operating in international jurisdictions where Suncor operates.

The Code is available on Suncor's web site.

Conflicts of Interest

The Board has adopted a policy relating to directors' conflicts of interest. Pursuant to this policy, directors are required to maintain with the Corporate Secretary a current list of all other entities in which they have a material interest, or on which they serve as a director, trustee or in a similar capacity. This list is made available to all directors through the directors' portal. Directors must immediately advise the Corporate Secretary of any deletions, additions or other changes to any information in their declaration of interest.

If the change involves a change in the director's principal occupation or an appointment as director, officer or trustee of any for-profit or not-for-profit organization, the director must also notify the chairman of the Board, who will determine whether the change would be inconsistent with the director's duties as a member of the Board. In appropriate circumstances, the director's resignation may be required.

The policy sets out clear procedures applicable in the event conflicts arise. If a director is a party to, or has an interest in any party to, a contract or transaction before the Board of Directors (regardless of the materiality of the contract or transaction), the director must immediately advise the chairman of the Board or the particular committee chair. The director's conflict or potential conflict is recorded in the minutes of the meeting and the director is required to absent himself or herself from the meeting for any material discussions or deliberations concerning the subject matter of the contract or transaction. The director is required to abstain from voting on any resolution in respect of such contract or transaction.

The Corporate Secretary ensures that directors do not receive Board materials in situations where the subject matter of those materials could involve an actual or potential conflict of interest.

Board and Committee Meetings

The chairman of the Board, in consultation with the Corporate Secretary, has the responsibility of establishing a schedule for the meetings of the Board of Directors and its committees each year, which is approved by the Board. Board and committee meeting dates are established sufficiently in advance where possible (at least one year and longer if practical) to minimize conflict with other commitments on directors' schedules. The Board holds at least five meetings per year, one of which is principally devoted to strategy. If, during the course of the year, circumstances require Board or committee action or consideration, additional meetings are called.

The chairman of the Board works with the CEO to establish the agenda for each Board meeting. The chair of each committee, in consultation with the committee secretary, determines the agenda for each committee meeting. Each Board member is free to suggest inclusion of items on any Board or committee agenda. Whenever feasible, important issues for decision are dealt with over the course of two meetings. The first meeting allows for a thorough briefing and the second allows for the final discussion and decision.

C-9 SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

Pursuant to the Terms of Reference, directors are expected to make every reasonable effort to attend all meetings of the Board and its committees. The following provides details about Board and committee meetings held during 2012 and the directors' attendance at these meetings.

Nomination of Directors

The selection process for new nominees for membership on the Board of Directors is conducted by the Governance Committee. More information on the responsibilities, powers and operations of the Governance Committee is found beginning on page 6 of this Schedule.

In considering its recommendations, the Governance Committee acknowledges that the Board's membership should represent a diversity of backgrounds, experience and skills. Directors are selected for their integrity and character, sound and independent judgment, breadth of experience, insight and knowledge and business acumen. Directors are expected to bring these personal qualities to their role as a Suncor director and apply sound business judgment to help the Board make wise decisions and provide thoughtful and informed counsel to senior management.

Pursuant to the policies of the Board, the assessment and selection process is undertaken by the Governance Committee as needed and consists of several steps, including maintaining and updating from time to time, an inventory of capabilities, competencies and skills of current Board members and of the Board as a whole, taking pending retirements into account, which is provided below. The Board has determined that the industry background and functional experience of the Board currently maps well to Suncor's business strategy, as well as its vision. Suncor's vision is to be a trusted steward of valuable natural resources. Guided by its values, Suncor leads the way to deliver economic prosperity, social wellbeing and a healthy environment, for today and tomorrow.

"An ever-green list of potential board candidates is maintained and updated as needed."
The above inventory is assessed as required to identify any capabilities, competencies, skills and qualities desired to be added to the Board in light of the Board's current needs and priorities. The Governance Committee uses this assessment as a basis for selection criteria describing the skills, experiences, qualifications, diversity and personal qualities desired in potential new Board members. The Governance Committee identifies candidates from a

number of sources, including executive search firms, or referrals from existing directors. When a vacancy occurs or is pending, the Governance Committee identifies a short list of potential candidates to pursue further, considering whether the candidates can devote sufficient time and resources to his or her duties as a Board member. The Governance Committee is required to retain an executive search firm or other third party expert to assist in completing reference and background checks on Board candidates. The Governance Committee may also engage these firms and experts to assist in carrying out any of its duties required to be carried out in relation to recruitment. Pursuant to Board policies, the Governance Committee is required to maintain and update as needed, a list of potential Board candidates for planned and unplanned vacancies through the form of an ever-green list.

Throughout the process, the Governance Committee provides updates to the Board and solicits input on candidates. Candidates are interviewed by members of the committee and other directors as deemed appropriate. The Governance Committee ultimately provides its recommendation to the full Board of Directors, which approves a nominee for submission to shareholders for election to the Board.

C-11 SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

Retirement

THE CHIEF EXECUTIVE OFFICER AND OTHER MANAGEMENT DIRECTORS ARE REQUIRED TO LEAVE THE BOARD UPON THEIR RETIREMENT FROM SUNCOR. ALL OTHER DIRECTORS, ABSENT EXCEPTIONAL CIRCUMSTANCES, MUST RETIRE AT THE SHAREHOLDER MEETING FOLLOWING HIS OR HER 72 ^ND BIRTHDAY.

The Board has adopted a Retirement and Change of Circumstance Policy. The policy provides that all directors, other than management directors, must retire from the Board upon completion of their term of office at the annual meeting of shareholders following their 72 ^nd birthday. The Governance Committee, in consultation with the chairman of the Board, has the authority under exceptional circumstances to recommend extension of the term of a Board member if the retirement of such director would not be in the best interests of Board continuity and effectiveness. Any such extension must be granted by the Board on the recommendation of the Governance Committee. The CEO and other management directors are required to leave the Board upon their retirement from Suncor.

"The Board has established an annual review process for the Board, its Committees, the Chairman, the Chair of each Committee and its members."
Assessment of DirectorsSuncor's Board Effectiveness Policy establishes an annual process (the "Evaluation Process") whereby directors are provided with an opportunity to evaluate the effectiveness of the Board, its committees, the chairman of the Board, committee chairs and Board members and to identify areas where effectiveness can be improved or enhanced in these areas. The Evaluation Process carried out in 2012 showed that all individuals and committees were effectively fulfilling their responsibilities.

The Evaluation Process involves the solicitation of input from individual directors through an annual on-line survey presented in two parts: (i) the Suncor Energy Board, Chairman of the Board and Committee Effectiveness Evaluation Form (the "Board Effectiveness Survey"), which explores the directors' views and solicits feedbacks on how well he or she believes the Board and its committees, including its chairs, are performing; and (ii) the Director Peer Feedback Survey (the "Peer Survey"), which explores the directors' views and solicits feedback on their assessment of other directors' performance, including their contributions, accountability, knowledge, experience and demonstration of high ethical standards.

The Evaluation Process includes open-ended questions to allow directors to suggest improvement. The Board Effectiveness Survey asks each director whether he or she believes the Board and each of its committees are functioning as they should in accordance with their mandates. Information obtained from the answers to these questions assists the Board in determining whether any of the Board or committee mandates or Board processes or policies need to be amended.

Board Effectiveness Review

Confidential responses are tabulated and analyzed by the Corporate Secretary and presented on a report which is circulated to the chair of the Governance Committee and chairman of the Board, who then work with the Corporate Secretary to summarize key items and recommendations for enhancing or strengthening effectiveness (including any recommendations arising from the one-on-one meetings described under "Peer Review" below). The recommendations are tabled, discussed and finalized at the Governance Committee meeting in January and timelines and action items are assigned at the meeting to track any follow-up to effect the recommendations. The chair of the Governance Committee reports to the full Board on the survey results, recommendations and action items at the January meeting of the Board and reports on the progress in completing those recommendations throughout the year. All materials distributed to the Governance Committee, including the consolidated report and recommendations, are made available for review by all directors.

Peer Review

The results of the Peer Survey are tabulated and consolidated by the Corporate Secretary and a summary report is circulated to the chair of the Governance Committee and chairman of the Board. Individual directors receive their personal results.

The chairman of the Board sets up one-on-one meetings with each director to discuss his or her peer review results and to receive the directors' input on governance, risk and strategy. The chairman of the Board discusses his own peer review results with the chair of the Governance Committee. The one-on-one meetings are completed prior to the Board and committee meetings held in January. This allows any input provided during the peer review on governance, risk and strategy, to be incorporated in the action plans arising from the Evaluation Process. Once the peer review meetings are completed, the chairman of the Board prepares a summary of key items arising from these discussions which are discussed in camera at the Governance Committee and at the meeting of the full Board.

D-2 SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

SCHEDULE E: DIRECTOR INDEPENDENCE POLICY AND CRITERIA

BACKGROUND:

Corporate governance guidelines provide that boards of directors should have a majority of independent directors, and that the board chairman should be independent.

The purpose of this independence policy and criteria is to state the criteria by which the Board of Directors (the "Board") of Suncor Energy Inc. ("Suncor") determines whether each of its directors is or is not independent.

INDEPENDENCE POLICY:

Pursuant to the terms of reference for the Board, a majority of the Board must be independent, and in addition, the Audit, Governance, and Human Resources and Compensation Committees, shall be comprised solely of independent directors. The Governance Committee will conduct an annual review of the status of each director and director nominee in light of the following criteria for independence, and will recommend to the Board in order that the Board may affirmatively determine the status of each such individual. In making independence determinations, the Board shall consider all relevant facts and circumstances. Material relationships can include commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships. The key concern when assessing independence is independence from management.

INDEPENDENCE CRITERIA:

A director of Suncor will be considered independent only if the Board has affirmatively determined that the director has no material relationship with Suncor, either directly or as a partner, shareholder or officer of an organization that has a material relationship with Suncor. A "material relationship" is one which could, in the view of the Board, be reasonably expected to interfere with the exercise of the director's independent judgment (CSA National Instrument 52-110).

Notwithstanding the foregoing, a director will NOT be considered independent if ⁽¹⁾:

•

The director is, or has been within the last three years, an employee or executive officer of Suncor, or an immediate family member is or has been within the last three years, an executive officer, of Suncor.

•

The director has received, or an immediate family member has received, during any 12-month period within the last three years, more than $75,000 in direct compensation from Suncor, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service) and other than compensation received by any immediate family member for service as an employee of Suncor (other than an executive officer).

•

The director or an immediate family member is a current partner of a firm that is Suncor's internal or external auditor; a director is a current employee of such a firm; or a director's immediate family member is a current employee of such a firm and participates in the firm's audit, assurance or tax compliance (but not tax planning) practice; or a director or an immediate family member who was within the last three years (but is no longer) a partner or employee of such a firm and personally worked on Suncor's audit within that time. For the purposes of this point ONLY, "immediate family member" means a spouse, minor child or stepchild, adult child or stepchild sharing a home with the director.

•

The director or any immediate family member is or has been within the last three years employed, as an executive officer of another corporation where any of Suncor's current executive officers at the same time serve on that corporation's compensation committee.

•

The director is a current employee, or an immediate family member is a current executive officer, of a corporation that has made payments to, or received payments from, Suncor, for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1 million, or 2% of such other corporation's consolidated gross revenues.

•

Contributions to tax exempt organizations shall not be considered "payments" for the purposes of these rules, provided that Suncor shall disclose in its proxy circular such contributions made to any tax exempt organization in which a director serves as an executive officer, if within the preceding three years, contributions in any single fiscal year from Suncor to the organization exceeded the greater of $1 million, or 2% of such organization's consolidated gross reserves.

•

For Audit Committee members only, in order to be considered independent, a member of the Audit Committee may not, other than in his or her capacity as a member of the Audit Committee, the Board or any other Board Committee, accept directly or indirectly any consulting, advisory, or other compensatory fee from Suncor, provided that compensatory fees do not include the receipt of fixed amounts of compensation under a retirement plan (including deferred compensation) for prior service with Suncor provided that such compensation is not contingent in any way on continued service; and in addition, shall not be an affiliated person of Suncor or any of its subsidiaries.

(1)

Unless otherwise noted, "immediate family member" is defined to include a person's spouse, parents, children, siblings, mothers and fathers in law, sons and daughters in law, brothers and sisters in law, and anyone other than domestic employees who shares such person's home.

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR E-1

A director of Suncor will not be considered to have a material relationship with Suncor solely because the individual or his or her immediate family member:

•

Has previously acted as an interim CEO of Suncor; or

•

Acts, or has previously acted, as chair or vice chair of the Board or of any Board committees on a part-time basis; or

•

Sits on the board of directors or as a trustee or in an equivalent capacity, of another corporation, firm or other entity, which has a business relationship with Suncor, provided that the individual's remuneration from the other entity is not personally material to that individual or dependent on or variable with the nature or extent of the business relationship with Suncor, the individual is not involved in negotiating, managing, administering or approving contracts between Suncor and the other entity, and the individual otherwise is in compliance with the Board's conflict of interest policy with respect to contracts between Suncor and that other entity.

E-2 SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

SCHEDULE F: BOARD TERMS OF REFERENCE

PART I: OVERVIEW

The Canada Business Corporations Act (the Act), Suncor Energy's governing statute, provides "that the directors shall manage or supervise the management of the business and affairs of a corporation...". In practice, as a Board of Directors cannot "manage" a corporation such as Suncor Energy in the sense of directing its day-to-day operations, the overarching role and legal duty of Suncor's Board of Directors is to "supervise" the management of Suncor's business and affairs. Accordingly, the Board of Directors oversees development of the overall strategic direction and policy framework for Suncor Energy. This responsibility is discharged through Board oversight of Suncor Energy's management, which is responsible for the day-to-day conduct of the business. The Board, through the Chief Executive Officer (CEO), sets standards of conduct, including the Corporation's general moral and ethical tone, compliance with applicable laws, standards for financial practices and reporting, qualitative standards for operations and products and other standards that reflect the views of the Board as to the conduct of the business in the best interests of the Corporation.

In general, then, the Board is responsible for the selection, monitoring and evaluation of executive management, and for overseeing the ways in which Suncor Energy's business and affairs are managed. In this way, the Board assumes responsibility for the stewardship of the Corporation. Specific responsibilities which facilitate the discharge of the Board's stewardship responsibilities include: the strategic planning process, risk identification and management, ensuring that effective stakeholder communication policies are in place, and ensuring the integrity of internal controls and management information systems. These responsibilities, and others, are addressed in more detail in the Board's Mandate, comprising Part IV of these Terms of Reference.

The Board of Directors discharges its responsibilities with the assistance of Board committees. The committees advise and formulate recommendations to the Board, but do not, except in limited and specifically identified circumstances, have the authority to approve matters on behalf of the Board of Directors. General guidelines relating to Board committees comprise Part III of these Terms of Reference. In addition, each committee has a written mandate, setting out the scope of its operations, and its key roles and responsibilities. Position descriptions of the Board Committee Chairs and the Board of Directors Chairman set out the related principles, framework and accountabilities for those key roles in Suncor's Board governance.

The CEO of Suncor Energy is delegated the responsibility for the day-to-day management of the Corporation and for providing the Corporation with leadership. The CEO discharges these responsibilities by formulating Corporation policies and proposed actions, and, where appropriate, presenting them to the Board for approval. The Corporation's Management Control Process Policy explicitly identifies actions which have been specifically delegated to the CEO, and those which are reserved to the Board of Directors. In addition, the Board has plenary power, and has the power to specify and modify the authority and duties of management as it sees fit with a view to Suncor Energy's best interests and in accordance with current standards. The Act also identifies certain matters which must be considered by the Board as a whole and may not be delegated to a committee or to management. These matters include:

•

any submission to the shareholders of a question or matter requiring the approval of the shareholders;

•

the filling of a vacancy among the directors or in the office of the external auditor;

•

the manner of and terms for the issuance of securities;

•

the declaration of dividends;

•

the purchase, redemption or any other form of acquisition of shares issued by the Corporation;

•

the payment of a commission to any person in consideration of the purchase or agreement to purchase shares of the Corporation from the Corporation or from any other person, or procuring or agreeing to procure purchasers for any such shares;

•

the approval of management proxy circulars;

•

the approval of any take-over bid circular or directors' circular;

•

the approval of the audited annual financial statements of the Corporation; and

•

the adoption, amendment or repeal of by-laws of the Corporation.

One of the key stewardship responsibilities of the Board is to approve the Corporation's goals, strategies and plans, and the fundamental objectives and policies within which the business is operated, and evaluate the performance of executive management. Once the Board has approved the goals, strategies and plans, it acts in a unified and cohesive manner in supporting and guiding the CEO. The CEO keeps the Board fully informed of the progress of the Corporation toward the achievement of its goals, strategies and plans, in a timely and candid manner, and the Board of Directors continually evaluates the performance of executive management toward these achievements.

SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR F-1

PART II: BOARD GUIDELINES

The following have been adopted by the Board as the guidelines applicable to the Board and its operations:

•

These Terms of Reference for the Board of Directors (which include the Board Guidelines, Committee Guidelines, Board Mandate and Board Forward Agenda, setting out the important issues that must be addressed by the Board of Directors annually), and the mandates and forward agendas of the Board committees, constitute the charters of the Board and committees respectively, and are reviewed by the Board annually and updated as deemed appropriate. These charters are supplemented by the position descriptions for the Board Chairman and Board Committee Chairs, as well as the Director Accountability Statement.

•

The CEO is responsible for leading the development of long-range plans for the Corporation, including its goals and strategies. The Board, both directly and through its committees, participates in discussions of strategy, by responding to and contributing ideas. The Board annually reviews and approves the Corporation's annual business plan (including the annual budget), and approves the strategies as reflected in the Corporation's long range plan.

•

The Board believes that the appropriate size for the Board is between 10 and 14 members.

•

Directors stand for re-election annually.

•

The Board maintains a Mandatory Retirement and Change of Circumstance Policy and reviews the policy periodically to ensure it continues to serve the Corporation's best interests. The Board maintains a policy permitting directors to retain outside advisors at the expense of the Corporation, subject to the written approval of any of the Board Chairman, the Chair of the committee proposing to retain outside advisors, or the Governance Committee. In exercising their approval authority, the Board Chairman, Board Committee Chair or Governance Committee, as the case may be, will establish, on a case by case basis, reasonable monetary limits and other controls as deemed appropriate.

•

In order to support the alignment of Directors' interests with those of Suncor's shareholders, Directors shall own during the term of their directorship within five years of being appointed or elected to the Board, a minimum value of Suncor common shares, DSUs or any combination thereof, as determined annually by the Human Resources and Compensation Committee.

•

The Board should be comprised of a majority of independent directors. The Board has defined an independent director in written independence criteria, based on definitions in the Canadian Requirements and the SEC Requirements ⁽¹⁾. On an annual basis, the Board of Directors shall consider and affirmatively determine whether each individual director is independent, in accordance with the criteria.

•

The membership of the CEO on the Board of Directors is valuable and conducive to effective decision making. However, there should generally be no more than three inside ⁽²⁾ directors on the Board of Directors.

•

The Board supports the separation of the role of Chairman from the role of CEO.

•

The Board will evaluate the performance of the CEO at least annually. The evaluation will be based on criteria which includes the performance of the business and the accomplishment of CEO's qualitative and quantitative objectives as established at the beginning of each fiscal year of the Corporation, and the creation and fostering within the Corporation of a culture of integrity.

•

The Board Chairman will work with the CEO to establish the agenda for each Board meeting. Each Board member is free to suggest the inclusion of items on the agenda. Whenever feasible, important issues should be dealt with over the course of two meetings. The first such meeting would allow for a thorough briefing of the Board, and the second would allow for final discussion and a decision.

•

The Board will hold at least five meetings per year, one of which shall be principally devoted to strategy. An additional meeting shall be scheduled for approval of the annual proxy circular, annual information form and other annual disclosure documents, as necessary.

•

Whenever feasible, the Board will receive materials at least one full weekend in advance of meetings. Presentations on specific subjects at Board meetings will only briefly summarize the material sent so discussion at the meeting can focus on questions and issues. Directors are expected to have reviewed these materials prior to attendance at Board and committee meetings, and are expected to be prepared to engage in meaningful discussion and provide considered, constructive and thoughtful feedback and commentary at meetings.

•

Board meeting dates will be established sufficiently in advance (at least one year and longer if practical) to minimize conflict with other commitments on Directors' schedules. Directors are accordingly expected to make every reasonable effort to attend all meetings of the Board and its committees, if not in person then by telephone.

(1)

Suncor's corporate governance practices reflect applicable rules and guidelines adopted by the Canadian Securities Administrators (the "Canadian Requirements") and the U.S. Securities and Exchange Commission ("SEC"), including applicable rules adopted by the SEC to give effect to the provisions of the Sarbanes Oxley Act of 2002 (collectively, the "SEC Requirements").

(2)

An inside director is an officer (other than an officer serving as such in a non-executive capacity) or employee of the Corporation.

F-2 SUNCOR ENERGY INC. 2013MANAGEMENT PROXY CIRCULAR

•

While the Board does not restrict the number of public company boards that a director may serve on, each director should ensure that he or she is able to devote sufficient time and energy to carrying out their duties effectively.

•

The Board encourages the CEO to bring other executive officers into Board meetings. The presence of such executives is expected to bring additional insights into the discussions, because of the executives' personal involvement in, and knowledge of, specific agenda items. The benefit of exposing the Board to other executives, for succession planning and career development purposes, is recognized.

•

The Board is responsible for selecting its own members, and for assessing the performance of individual directors, as well as the effectiveness of Board committees and the Board of Directors as a whole. The Board delegates management of the selection processes to the Governance Committee. The Governance Committee has established a policy for director selection. The selection process includes consideration of the competencies and skills the Board, as a whole, should possess, against those of existing directors, and a consideration of the competencies and skills each new nominee will bring to the Board, as well as their ability to devote sufficient time and attention to fulfilling the role of director. The Board ultimately determines nominees that will be included in the Corporation's management proxy circular.

•

The outgoing Chairman of the Board, or in the absence of the outgoing Chairman, a director elected by resolution of the Board, shall manage the process of electing a new Chairman by seeking nominations, determining the willingness of each nominee to take on the role of Chairman of the Board, and by presiding over an election by secret ballot.

•

The Board supports the principle that its membership should represent a diversity of backgrounds, experience and skills.

•

Succession and management development plans will be reviewed by the Human Resources & Compensation Committee, and reported on annually to the Board.

•

At the conclusion of each Board meeting, the Board of Directors shall meet on an "in camera" basis without management. Such in camera meetings shall be presided over by the independent Chairman. In addition, at least once annually, the independent directors will meet in the absence of both management and non-independent directors.

•

At least once annually, the Board will meet at a Suncor Energy location other than the head office location. The purpose is to facilitate continual exposure of Board members to the Corporation's operations and the communities in which they are carried out.

PART III: COMMITTEE GUIDELINES

•

The Board has four standing committees: the Audit Committee, the Governance Committee, the Human Resources and Compensation Committee ("HR&CC"), and the Environment, Health, Safety & Sustainable Development Committee ("EHS&SD"). From time to time the Board may create ad hoc committees to examine specific issues on behalf of the Board. Each committee maintains a written mandate and reviews that mandate annually. Any recommendations to amend committee mandates are reviewed by the Governance Committee for recommendation to the Board of Directors.

•

The Governance Committee, with input from the Chairman of the Board, plans Board committee appointments (including the designation of a committee Chair) for recommendation to and appointment by the Board. The committees shall be reconstituted annually following the annual general meeting at which directors are elected by the shareholders of the Corporation. In accordance with the Corporation's By-laws, unless otherwise determined by resolution of the Board of Directors, a majority of the members of a committee shall constitute a quorum for meetings of committees.

•

Each committee shall be comprised of a minimum of three and a maximum of six directors. Each committee shall have a non-member Secretary who may be a member of management of the Corporation. The Chair of each committee, in consultation with the committee Secretary, shall determine the agenda for each committee meeting.

•

The Board supports the principle that committee Chairs should be rotated regularly while preserving continuity.

•

Except where otherwise specified in these terms of reference or in the Corporation's By-laws, each committee shall have the power to determine its own rules of procedure.

•

The Audit Committee will consist entirely of outside, independent ⁽³⁾ directors. In addition, all members of the Audit committee must be, in the judgment of the Board of the Directors, financially literate ⁽⁴⁾, and at least one member of the Audit Committee must be an audit committee financial expert ⁽⁵⁾.

•

In general Audit Committee members will not simultaneously be members of the Audit Committee of more than two other public companies, unless the Board of Directors affirmatively determines that simultaneous service on a greater number of audit committees would not impair the member's ability to effectively serve on Suncor's Audit Committee. Any such determination by the Board of Directors shall be disclosed in the Corporation's management proxy circular.

•

The HR&CC will consist entirely of outside, independent directors.
