  the election of directors of the Corporation until the close of the next annual meeting; and
•
  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 person named in the proxy form will have discretionary authority with respect to amendments or variations to matters identified in the Notice of Annual 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.

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 signing and returning your proxy form in the prepaid envelope provided or by voting using the internet at www.investorvote.com or by calling 1-866-732-VOTE (8683).

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.

2 SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR

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; and
•
  FOR the appointment of PricewaterhouseCoopers LLP as auditors.

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

A. Yes, you have the right to appoint the person 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, on 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 require 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
2.
  delivering a written statement, signed by you or your authorized attorney to:
  (a)
    the Corporate Secretary of Suncor Energy Inc. at 112 - 4th Avenue SW, Calgary, Alberta, T2P 2V5 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 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 26, 2010, there were 1,560,828,439 common shares outstanding. We have no other class or series of voting shares outstanding.

BUSINESS OF THE MEETING

FINANCIAL STATEMENTS

The consolidated financial statements for the year ended December 31, 2009 are included in the 2009 Annual Report.

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 14 directors. In accordance with our by-laws, the Board of Directors has determined that 14 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 6 to 9. 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 of Directors has adopted a policy which 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 of Directors 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 of Directors. The Board of Directors 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 of Directors' 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.

COMPENSATION DISCUSSION & ANALYSIS

BOARD OF DIRECTORS COMPENSATION

Suncor's Board of Directors is composed of Richard L. George, our president and chief executive officer ("CEO"), and 13 independant non-employee directors, including seven who were on the board of Suncor, four who were on the board of Petro-Canada prior to the merger, and two who joined the Board in November. The compensation of the 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 directors' interests with shareholder interests. Director compensation is not performance based. The Governance Committee reviews board compensation levels annually to ensure Suncor's approach to Board compensation is competitive, reflects best practice and takes relevant governance trends into account.

EQUITY-BASED COMPENSATION

Annual DSU Grant. Non-employee directors participate in the Suncor Deferred Share Unit Plan (the "DSU Plan"). Under the DSU Plan, each non-employee director receives an annual grant of deferred share units ("DSUs") as part of their competitive total compensation. In 2009 the annual grant for each non-employee director, other than the chairman of the Board, was 5,500 DSUs. The chairman received 8,000 DSUs. On August 1, 2009, a pro-rata annual grant of 2,300 DSUs was made to Petro-Canada non-employee directors continuing with the new Suncor Board. The DSU plan also provides for an additional initial grant of DSUs equal to the annual grant to each new director upon their election or appointment to the Board. In 2009, initial grants of 5,500 DSUs were made to each of Mr. D'Alessandro and Mr. Lamarre on November 12, 2009.

Fees Paid in DSUs. Until the Board's share ownership guidelines (see page 15 for details) are met, 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. In 2009, non-employee directors received an aggregate total of 133,671 DSUs.

Redemption of DSUs. DSUs will be redeemed when the director ceases to hold office as a director, or on a date elected by that director prior to November 30 of the following year. For directors subject to payment of U.S. federal tax, the redemption period to elect payout of DSUs starts on the first day of the first calendar year following the year in which the directorship ceased and ends on November 30 of that same year. The cash payment is calculated by multiplying the number of DSUs by the then-current market value of a common share.

Stock Options. Stock option grants to non-employee directors were discontinued after 2008. No future stock option grants to non-employee directors are planned. For information on previously granted options to Suncor directors, see Schedule A (current directors) and Schedule C (non-continuing directors) to this Information Circular. For a description of the plan under which prior awards were granted, see "Summary of Incentive Plans" on page 31.

14 SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR

Looking Ahead to 2010 – Changes to Compensation Mix. In November 2009, the new Suncor Board reviewed current total compensation for non-employee directors and the chairman of the Board in light of the merger with Petro-Canada. Based on an assessment of Suncor's total compensation versus a competitive market data analysis conducted by Towers Watson for a new North American energy peer group (see page 18), the Board determined the current level of total compensation, which is at the median of total compensation for the peer group, is appropriate for 2010.

The Board approved a change to the mix of fees and equity-based compensation (DSUs) for non-employee directors in 2010. The change was made to move towards a more market typical weighting of cash fees and equity-based compensation. The effect of the change is to increase fees for certain positions on the Board and to move the mix of fees and equity-based compensation for non-employee directors from the current 25%/75% weighting to 30%/70%, respectively.

Share Ownership Guidelines

One way directors demonstrate their commitment to Suncor's long term success is through share ownership. The Board has established share ownership guidelines for non-employee directors which must be attained within five years of their appointment or election.

2009 Guidelines. The 2009 guidelines are based on a target of three times the market median compensation for directors of large Canadian energy companies. For 2009, each director, within five years of the date of appointment is required to own Suncor common shares and/or DSUs with a market value of $540,000, and the chairman of the Board is required to own Suncor common shares and/or DSUs with a market value of $1,200,000. As of the date of this Information Circular, all directors, including the chairman of the Board, were in compliance with the share ownership guidelines.

2010 Guidelines. Share ownership guidelines were assessed as part of the November 2009 review of total compensation for non-employee directors. The current share ownership guideline level for directors was determined to be appropriate for a company with the size and scope of Suncor. The only change made for 2010 was to increase the chairman of the Board's guideline level to $1,400,000.

SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR 15

EXECUTIVE COMPENSATION

The merger in 2009 of Suncor and Petro-Canada created the largest energy company in Canada and one of the largest energy companies in North America by market capitalization. The merged Suncor is a Canadian energy leader with the assets, cost structure and financial base to compete globally and creates a solid foundation for developing future shareholder value.

Central to the role of the Board of Directors' Human Resources and Compensation Committee ("HR&CC") is the alignment of executive compensation with the delivery of shareholder value.

While Suncor and Petro-Canada shared a similar "pay for performance" compensation philosophy with strong governance and risk management principles integral to their compensation structure, there were differences in compensation systems. With the merger completed, Suncor – under the oversight of the HR&CC – is aligning and strengthening performance-based compensation structures.

Effectively balancing and managing risk and reward is an important and integrated part of Suncor's approach to executive compensation. Minimum target thresholds will ensure greater alignment to shareholder interests, while incentive caps and "performance-against-peers" provisions mitigate the risk of excessive awards based on uncontrollable commodity cycles. In addition, we continue to monitor evolving governance and competitive practices to ensure that our programs are aligned with shareholder interests and our corporate philosophy of continuous improvement. In addition to describing executive compensation in 2009, the following section includes a discussion of certain improvements planned to performance-based compensation programs going forward.

GOVERNANCE

Board of Directors. The Board oversees development of the overall strategic direction and policy framework for Suncor. This responsibility, in part, is discharged with the assistance of Board committees. Generally, the committees advise and develop recommendations to the Board. Guidelines relating to Board committees can be found in Schedule E. On August 1, 2009, the Board assembled a new HR&CC, with members from both legacy organizations, to maximize director knowledge and experience and to provide an effective team to oversee the needs of the larger, more complex organization.

Human Resources and Compensation Committee. The HR&CC assists the Board by:

•
  reviewing and approving annually the overall corporate goals and objectives of Suncor relevant to compensation of the CEO, and ensuring that the overall goals and objectives of Suncor are supported by an appropriate executive compensation philosophy and programs;
•
  evaluating annually the performance of the CEO against predetermined goals and criteria, and recommending to the Board of Directors the total compensation for the CEO in light of their evaluation of the CEO's performance;
•
  reviewing annually the CEO's evaluation of the other executives' performance and recommendation for total compensation of the other executives;
•
  reviewing annually the succession planning process and results of the process as it relates to the executive roles; ensuring that a full review of candidates for the president & CEO and senior executive positions is provided to the Board as described herein; and
•
  reviewing, on a summary basis, any significant compensation, pension and benefit programs for employees generally, with consideration to accounting, tax, design, legal, regulatory environment, and pay and performance relationship for variable pay.

All HR&CC members are independent directors. HR&CC membership currently consists of: James Simpson (chair), Mel Benson, Doug Ford, John Huff, Jacques Lamarre, and Maureen McCaw.

Independent Executive Compensation Consultants. The HR&CC retains an independent executive compensation consultant to help discharge its mandate.

Prior to the merger, Suncor used a single executive compensation consulting firm Towers Watson, which had protocols in place to ensure they were in a position to provide independent advice and reported directly to the HR&CC. Towers Watson supported Suncor in the area of executive compensation as well as other human resources areas, including assistance with the merger integration process. The HR&CC received information and consulting support from Towers Watson in the following areas:

•
  expertise and advice in the development of compensation policies and programs for executives and directors;
•
  periodic updates to the HR&CC on best practices, trends and emerging regulatory or governance matters related to executive and director compensation; and

16 SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR

•
  custom survey work benchmarking Suncor compensation in the marketplace.

The HR&CC moved to a two-consultant model mid-2009 and engaged Hewitt Associates as their independent advisor. Hewitt Associates' role is to review and audit the recommendations and work put forward by management and Towers Watson and to provide independent compensation advice and perspective to the HR&CC. The Suncor (Management) Pension Investment Committee retained Hewitt as its investment advisor in November 2009.

The decisions made by the HR&CC may reflect factors and considerations other than the information provided or recommendations made by our independent compensation consultants. During 2009, Towers Watson and Hewitt Associates met with the HR&CC chair and attended relevant sections of HR&CC meetings, as necessary.

Fees paid by Suncor in 2009 to Hewitt Associates were $42,272, and to Towers Watson for executive compensation services, independent from and not including merger related activities, were $151,102.

2009 Highlights. Highlights of governance-related decisions by the HR&CC in 2009 include:

•
  Reduced the targeted award level of long-term equity-based incentives granted in 2009, to reflect the performance of the market and reinforce the alignment of executive compensation with shareholder interests.
•
  Delayed 2009 salary increases for all legacy Suncor employees in response to the economic downturn. A salary adjustment was made in the fourth quarter after consideration of competitive data and improved economic conditions.
•
  Redesigned the annual incentive plan, effective August 1, 2009, to reflect a more market-typical design. This resulted in a simpler design while retaining the strong emphasis on performance at the corporate, business unit and individual level and further strengthening the link to pay for performance.

Looking Ahead to 2010 – Governance of our Compensation Program. Highlights of governance-related decisions by the HR&CC that take effect in 2010 include:

•
  Introduced a minimum performance threshold for the corporate cash flow measure. The minimum threshold level must be achieved before a payout under the annual incentive plan can be made. This change will ensure annual incentive payouts are realized only when cash flow is a significant contributor to business results.
•
  Changed the peer group for determining market-competitive compensation for our top twelve executive officers. To better reflect Suncor's new size and scope of operations and the market in which we compete for talent, we have moved from a group of large Canadian energy companies (of which Suncor is now the largest) to a group of North American energy companies.
•
  Increased the share ownership guidelines for the CEO, Chief Operating Officer ("COO") and executive vice-president levels to better align with our new North American peer group.
•
  Decided to introduce a "Say on Pay" advisory vote in 2011. Suncor received a shareholder proposal from SHARE, on behalf of Meritas Mutual Funds, which was subsequently withdrawn as we agreed to place before our shareholders at our 2011 annual meeting of shareholders, an advisory vote on our approach to executive compensation.

OUR APPROACH TO EXECUTIVE COMPENSATION

Pay for Performance Philosophy. Suncor continues to have a strong pay for performance philosophy. Our compensation plans and practices are linked to our strategic business objectives, as a significant portion of the total compensation of our senior executives is at-risk, incentive-based pay, designed to reward superior business performance and increasing shareholder returns. This is a fundamental part of who we are as an organization. This philosophy is demonstrated in the mix of compensation provided. For senior executives, incentive-based pay is designed to reward successful short, medium and long-term performance in key business areas such as safety, environment, cash flow, and operating reliability, all of which enable the performance results important to our shareholders.

SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR 17

Looking Ahead to 2010 – Links to Risk Management. Suncor's incentive plans and practices are designed with sufficient controls and limits in place to enhance the link between compensation and risk management and protect against undue risk to drive short term gains. Examples of this fundamental element of our performance based compensation philosophy include:

•
  Threshold financial targets in the annual incentive program that enhance the at risk profile of compensation.
•
  Annual review of performance targets with the internal risk management group to objectively assess the validity of identified priorities and targets.
•
  Mid and long-term equity incentives that align decision making with sustainable business results.
•
  Increased share ownership requirements for the CEO, COO, and executive vice presidents.

Finding the Right Balance. It is essential to Suncor's performance that we attract and retain highly skilled individuals at all levels of the organization. In particular, we need leaders who can execute on current priorities and position Suncor for long-term sustained success. We believe it is essential to provide an attractive and competitive total compensation opportunity. We believe we have the right balance through our "direct compensation", consisting of salary, annual incentives and longer-term equity-based incentives, as well as through our "indirect compensation", consisting of benefits, retirement-related programs and perquisites. We compliment these programs with excellent career development opportunities and careful succession planning.

Defining Our Marketplace. Suncor's merger with Petro-Canada increased Suncor's size and business scope. Following the merger, we re-defined the marketplace used to establish competitive compensation levels for our senior executives. The peer group going forward for determining competitive compensation for Suncor's top 12 executives, including the CEO, COO and Chief Financial Officer ("CFO"), is energy sector specific and comprised of organizations that are similar to Suncor in terms of size, scope and complexity. Our new peer group is comprised of 19 North American energy companies. For consistency, a similar peer group will be used for determining the relative total shareholder return performance for future grants of our Performance Share Units.

For our top twelve executive officers, including the continuing executives listed in the Summary Compensation Table on page 25 (the "Named Executive Officers"), annual total direct compensation (which includes base salary, annual incentive and annual long-term incentive grants) is targeted at the median of the following peer group of North American Energy companies:

Anadarko Petroleum Corporation |  | Apache Corporation |
Canadian Natural Resources Ltd. |  | Cenovus Energy Inc. |
Chesapeake Energy Corporation |  | Chevron Corporation |
Conoco Phillips |  | Devon Energy Corporation |
Enbridge Inc. |  | EnCana Corporation |
EOG Resources Inc. |  | Hess Corporation |
Husky Energy Inc. |  | Imperial Oil Ltd. |
Marathon Oil Corporation |  | Nexen Inc. |
Occidental Petroleum Corporation |  | Talisman Energy Inc. |
TransCanada Corporation |  |  |

For other executives, typically Vice-Presidents, annual total direct compensation is targeted at the 65th percentile of the following peer group of twelve large Canadian energy companies:

Canadian Natural Resources Ltd. |  | Canadian Oil Sands Trust |
Cenovus Energy Inc. |  | Devon Energy Corporation (Canada) |
Enbridge Inc. |  | EnCana Corporation |
Husky Energy Inc. |  | Imperial Oil Ltd. |
Nexen Inc. |  | Syncrude Canada Ltd. |
Talisman Energy Inc. |  | TransCanada Corporation |

EXECUTIVE COMPENSATION COMPONENTS: BASE SALARY + AT RISK COMPENSATION

Suncor's pay for performance compensation philosophy is the same for all executives. This philosophy is demonstrated in the mix of compensation provided. Total direct compensation, made up of base salary, annual and mid – long term incentives, is designed to reward achievement of short term goals and delivery of sustained performance in key business areas that enable the operational and financial results important to our shareholders. The total direct compensation components are outlined below.

18 SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR

Base Salary

Our Approach. At Suncor, base salary represents fixed compensation for discharging job responsibilities and reflects the level of skills and capabilities demonstrated by the executive. A base salary structure for job levels based on external market data and internal comparability is used. Annual salary adjustments take into account the market value of the role and the executive's demonstration of capability during the year. In 2009, Suncor targeted base salary at the median of our peer group. Some executive base salaries were adjusted in the fourth quarter to appropriately reflect the scope of post merger roles and to provide more appropriate competitive positioning.

At Risk Compensation

Annual Incentives. Our Annual Incentive Plan ("AI") provides the opportunity to earn awards based on the achievement of pre-established annual goals. Awards for business unit executives are based on a combination of corporate performance, the performance of the executive's business unit, and the executive's performance against their personal goals. Awards for corporate executives are determined based on corporate performance, a weighted average of business unit performance, and performance against their personal goals. To reinforce sustainable overall corporate success, Suncor's AI is designed so that business unit executives have a higher portion of their incentive opportunity linked to overall corporate results versus their individual business unit results. In 2009, the AI payout opportunity, expressed as a percentage of base salary, was unchanged from the previous year.

AI measures for executives target corporate and business unit performance in key areas important to achieving operational excellence and delivering shareholder value. These measurement areas include cash flow, safety, environment, reliability (production, cost, asset availability) and people. The AI payout opportunity can range from 0% to 220% of target and is weighted 20% on corporate measure results, 60% on business unit performance and 20% on personal performance.

Looking Ahead to 2010 – Threshold Financial Measures. For 2010, we introduced a minimum performance threshold on the corporate cash flow measure that must be achieved before a payout under the annual incentive plan can be made. This change will ensure annual incentive payouts are realized only when business results drive shareholder value.

Mid and Long-Term Incentives. Our executives and other senior management participate in mid and long-term incentive plans that are based on the market value of our common shares. The link to our share price and our performance compared to our peers reinforces alignment with shareholder interests. For 2009, the target grant for incentives was reduced to recognize the market conditions and the resulting impact on Suncor's share price.

The following is a brief description of Suncor's mid and long-term incentive plans for executives:

(i)
  Suncor Stock Option Plan ("SOP") – provides for annual stock option grants with tandem stock appreciation rights ("SARs").
(ii)
  Performance Share Unit Plan ("PSU Plan") – provides for annual performance share unit ("PSU") grants which payout based on relative total shareholder return; and
(iii)
  Restricted Share Unit Plan ("RSU Plan") – provides for restricted share unit ("RSU") grants.

See "Summary of Incentive Plans" on pages 31 to 35 for a description of these plans and of plans that have been closed following the merger. Upon closing of the merger between Suncor and Petro-Canada, Petro-Canada shares and options (or other equity-based units) were exchanged for Suncor shares and options (or other equity-based units) at the exchange rate of 1.28 Suncor common shares or equity-based units for each Petro-Canada share or equity-based unit, as applicable. In addition, exercise prices were adjusted so that each equity holder could purchase 1.28 Suncor shares for the same price as one Petro-Canada share prior to the merger.

At risk pay is made up of annual and mid-long term incentives and represents a significant portion of total direct compensation for executives. The percentage of at risk versus fixed compensation increases as a portion of total direct compensation with greater levels of responsibility. This is illustrated in the chart below.

SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR 19

2010 Incentive Grants. Effective February 5, 2010, the Board of Directors approved the grant of options (including tandem SARs) and PSUs to certain of the continuing Named Executive Officers, as provided in the table below, and to certain other eligible employees under the terms of the SOP, and the PSU Plan. The grant price of the options is $31.85 per share, which is based on the average of the high and low market price of Suncor common shares on February 4, 2010. Each option granted to executive officers, including certain of the continuing Named Executive Officers, was awarded with an associated limited appreciation right ("LAR", further details of which are on page 29).

Executive Share Ownership Guidelines

Suncor strongly believes that executives' interests should be aligned with the interests of Suncor's shareholders. Executives demonstrate their commitment to Suncor's success by holding shares or share equivalents equal to a multiple of their base salary depending on executive level.

2009 Guidelines: The share ownership guideline level is to be achieved within five years of appointment to an executive position or increase in guideline level. Suncor common shares and DSUs count toward fulfillment of the guidelines. As of the date of this Information Circular, all executives are in compliance with the 2009 guidelines indicated in the table below.

Looking Ahead – Increasing Alignment with Shareholders. In 2009, in light of the merger with Petro-Canada, we tested the competitiveness of our share ownership guidelines and have increased the guidelines for specific executive levels commencing January 1, 2010. Our new executive share ownership guidelines are described in the table below.

Position |  | Effective January 1, 2010 |  | 2009 Guideline |
CEO |  | 5 × annual salary |  | 4 × annual salary |
COO |  | 4 × annual salary |  | 3 × annual salary |
EVP |  | 3 × annual salary |  | 2 × annual salary |
SVP |  | 2 × annual salary |  | 2 × annual salary |

COMPENSATION OF THE PRESIDENT AND CHIEF EXECUTIVE OFFICER

2009 President & Chief Executive Officer Performance

The Board evaluated Mr. George's performance as "Exceptional" for 2009. The successful completion of the merger, leadership on key strategic issues and generally excellent operating results are the basis for the Board's overall assessment. While financial results relative to targets set before the merger are in some cases difficult to assess, the full year financial results did not fully achieve expectations.

The Board notes that the merger with Petro-Canada was the largest – and one of the most complex – corporate combinations in Canada's history. Despite this, it was completed exceptionally quickly from the announcement of intention in March, through shareholder approval (98% of shares voted in favour) in June, Competition Bureau of Canada approval in July and closure on August 1. Integration of corporate structures and business operations, along with identification and realization of synergies, has progressed on a similarly rapid pace through the end of 2009 and is ongoing in 2010.

The Board believes that the combination with Petro-Canada creates a stronger financial foundation for Suncor, maintains a strong growth profile, increases flexibility, and provides synergies and economies of scale that are expected to contribute to future shareholder value. Delivering on the expected benefits of the merger – while stewarding stronger and more reliable operational and financial results in the context of an expanded business and continuing weakness in the economy will be important measures in the success of our business.

While the merger was central to Mr. George's accomplishments in 2009, he continued to lead and deliver results against his annual performance objectives. The following is a summary for each of the key performance areas.

20 SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR

Financial and operating results achieved during 2009. Through a very volatile period, Mr. George provided strong leadership, steering Suncor through intense activity related to the merger with Petro-Canada and unstable global markets.

Operational results as compared to pre-merger targets were strong. Oil sands production was initially targeted at 270,000 to 315,000 barrels per day (bpd) with a corresponding cash operating cost of $33 to $38 per barrel. Unscheduled maintenance did impact annualized production and costs, but full-year results were well within target at 290,600 bpd and a corresponding cash operating cost of $33.95 per barrel, at the low (positive) end of target range. Generally strong results through the year were, however, diminished by a fire and subsequent maintenance outage at portions of the company's oil sands facilities in December.

Natural gas production from legacy Suncor assets was in the middle of the targeted range of 200 to 220 mmcf equivalent per day at 210 mmcf equivalent per day, supporting management's strategic goal of producing sufficient natural gas volumes to exceed consumption at the company's oil sands operations.

Continuing efforts to improve reliability and position Suncor for stronger performance, Mr. George worked with the Chief Operating Officer in developing and advancing strategies focused on operational excellence, with specific goals to improve reliability, workforce efficiency and engagement, personal and process safety and environmental performance. Operationally, these initiatives yielded both increased production and improved cash operating costs (as noted above), while also contributing to reduced water use at the company's oil sands facilities and better management of energy consumption and related emissions.

Additional environmental improvements in 2009 include Suncor's continuing development of, and regulatory application to employ, new tailings management technology and processes that are expected to significantly reduce the need for future tailings treatment ponds at the company's oil sands mining operations, reducing impacts to surface land as well as reducing ongoing costs for reclamation. Underlining Suncor's commitment to leadership on environmental performance and continuous improvement, Mr. George endorsed setting ambitious and specific environmental improvement goals related to air emissions, water use, energy efficiency and surface land reclamation. These goals now stand as part of Suncor's corporate growth strategy.

While Suncor is among the energy industry's top safety performers, Mr. George oversaw strategies to make continued advances in process safety management through the corporate EHS organization and engagement of third party experts. Efforts also continued on strengthening personal safety, resulting in improved safety performance and contributing to Suncor remaining among the best in the energy industry.

Annual financial results compared to initial targets are difficult to assess in light of the merger. However, the Board notes that fourth quarter 2009 results – the first full quarter of operations for the merged company – did not meet expectations and contributed to lower than expected results on an annual basis. Strategic planning to strengthen the foundation for future performance and shareholder value going forward were fully launched on completion of the merger in August 2009 and are discussed in the following section.

Strategic planning to support future shareholder value. The Board's review of Mr. George's 2009 performance recognized the significant deterioration in global economic conditions (including key commodity benchmark prices), the increasing cost of access to debt markets, and the associated need to recalibrate growth plans to protect current and future shareholder value. In light of these conditions, capital spending was limited largely to safely and reliably sustaining existing cash-generating operations, while placing major growth projects into "safe mode" to protect those assets and allow for a rapid restart of construction at the appropriate time.

In the fourth quarter, restart of construction work on the Firebag Stage 3 in-situ oil sands expansion was announced, based on its estimated return on investment, potential to deliver nearest-term cash flow among the project portfolio, and to take advantage of the much less restricted labour and material markets that existed at the end of 2009. Construction of naphtha treatment facilities to add value to existing oil sands production volumes, and a biofuels production plant were restarted for similar reasons.

These 2009 initiatives led by Mr. George were the first stages of an ongoing strategic review of Suncor's asset portfolio and related growth strategy, including the announced intention to divest of non-core assets. This work is focused on rebalancing Suncor's development portfolio toward the oil sands – which strategically differentiates Suncor from its competitors – and optimizing near-term cash flow and reducing debt to strengthen the merged company's balance sheet.

Leadership on policy, social and environmental issues. Leadership efforts on policy issues in 2009 were muted somewhat by the demands of the merger. However, significant efforts were directed toward advancing royalty-related issues with the Province of Alberta and working with government leaders on policy implications related to proposed low-carbon fuel standards in British Columbia, Alberta and the U.S. Midwest. Policy and regulatory leadership related to the merger itself was substantial, including providing information to elected officials and civil servants, and oversight of the Competition Bureau review process.

In leadership roles outside Suncor in 2009, Mr. George served on a Canadian Association of Petroleum Producers CEO task group providing leadership and direction on improving the industry's engagement with policy-makers, non-governmental advocates and the Canadian public on social and environmental issues related to oil sands development.

SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR 21

Talent Management. The merger of Suncor and Petro-Canada placed additional emphasis on this key performance area. As with other aspects of the merger, Mr. George moved quickly to establish the new Suncor senior leadership team, planning the appointments in consultation with the Board prior to the close of the merger. Selection and reporting structure for leaders through to mid-management were largely in place within weeks of the close of the merger, allowing the organization to focus on safe, reliable and efficient business operations. With the new organization fully stabilizing, the company's Suncor University, which continued to run through the merger process, will be revised to ensure continued development of executive and manager level leadership, with a goal of continuously improving management performance and developing future senior leadership succession candidates.

Effective relationship with the Board of Directors. As stewards of shareholder interests, the independent members of the Board of Directors must have a close working relationship with executive leadership. Mr. George has kept the Board fully and transparently informed on issues of financial, operational and strategic importance and has ensured that senior executives and technical experts are also available to the Board.

2009 Compensation of the President & CEO

Suncor's compensation structure for Mr. George places a significant portion of his pay at risk. Based on actual payments for 2009, base salary comprised 19% of Mr. George's total direct compensation. His annual performance-based incentive payment contributed an additional 26%, and his mid and long-term incentives, contributed the remaining 55% (all percentages are approximate).

At Risk Pay

Base Salary. Base salary is the only portion of the CEO's (and the Named Executive Officers') direct compensation that is not "at risk" and not therefore not directly tied to corporate performance and shareholder value. The base salary level for the CEO is reviewed annually by the HR&CC based on comparison to president and chief executive officer positions at the median of our peer group of companies.

Annual Incentive. The CEO's 2009 annual incentive target is 90% of his base salary. The 2009 annual incentive payout can range from 0% to a maximum of 220% of incentive target.

In preparation for assessing the CEO's personal performance a detailed questionnaire is completed by all board members with focus on established attributes and performance criteria. This information is collected and reviewed by the Chairman of the Board and the HR&CC and a final performance rating is established.

The actual payout for 2009 based on Suncor's financial and operational performance and the Board's evaluation of the CEO's individual performance was $1,800,000. The following table displays the pre-merger and post-merger components of the CEO's 2009 award.

22 SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR

For 2009, the seven month pre-merger component of the CEO's payout was weighted 20% on Suncor's cash flow from operations and 80% on the weighted average of the business unit's performance versus targets: safety, environment, reliability (production, cost, asset availability) and people, approved by the Board of Directors. The annual incentive amount for pre-merger period of $775,000 was based on a combined corporate and business unit score of 120%, and did not include consideration of personal performance. The Board determined that the CEO's performance against his personal goals would be assessed at the end of 2009, for the full year.

The post merger component of the CEO's 2009 payout was weighted 20% on two Corporate wide performance measures: cash flow from operations post merger and merger synergies realized, 60% on the weighted average of the business unit performance versus targets and 20% on the CEO's personal performance. The annual incentive amount for the post merger period was $1,025,000 based on a combined corporate and business unit score of 104% and consideration of the CEO's personal performance for the full year.

Mid- Long term Incentive. Mid- Long term incentive awards for the CEO reward performance in relation to increases to Suncor's common share price and to achieving specific performance thresholds. The deemed value of these awards at the time they are granted is based on expectations of future performance which, if not met, will reduce or negate the actual pay-out value of these awards

For specific details on Mr. George's compensation for 2009, see the "Summary Compensation Table" on page 25.

Long-Term Shareholder Value and Executive Compensation. Suncor's common shares closed at $37.21 on the Toronto Stock Exchange ("TSX") on December 31, 2009, an increase of approximately 57% over the year before, reflecting production reliability and cost improvement, overall market recovery and increased benchmark commodity prices.

The Board recognizes that in an industry subject to commodity price cycles, Suncor's focus is on long-term shareholder value growth. From 2004 to 2009, Suncor's share price increased by nearly 80%. The following performance graph shows Suncor's total cumulative shareholder return for the past five years.

Performance graph (1)(2)

  The graph reflects the total cumulative return, assuming the reinvestment of all dividends, of $100 invested on December 31, 2004 in each of Suncor Energy Inc. 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 share price appreciation plus dividend reinvestment.

Compensation levels for the Named Executive Officers over the period 2004 to 2009 are generally consistent with the trend of total return on investment charted for Suncor in the performance graph, reflecting the high proportion of "at risk" compensation for Suncor's Named Executive Officers. Total direct compensation for the Named Executive Officers consisting of base salary, annual incentive payment and the value of the annual equity award is used for the comparison over the period.

As a significant portion of compensation is equity-based, pay provided to the Named Executive Officers has been consistent with the Suncor's common share price performance and the current economic environment. While the Named Executive Officers generally experienced value growth from 2004 to 2007, the downturn in the market and the resulting decline in the Suncor share price has resulted in three of the last five years of option awards, including the SunShare 2012 Plan performance options, having no intrinsic value as at December 31, 2009. In addition, the last three years of PSU awards have not paid out or are currently tracking at a zero payout.

The HR&CC annually reviews a broader analysis of the total compensation earned and accruing to the president and CEO since his appointment and relates it to total shareholder return during the same period. In its recent review, the HR&CC related the total accrued compensation earned by the president and CEO up to December 31, 2009 to both the absolute increase in market capitalization, and the relative increase in market capitalization versus a relevant index, over the same period and found it to be reasonable.

  The grant date fair values for grants: January 2009 – ESP options $8.58, RSUs (annual grant) $21.07, PSUs $18.13; October 2009 – RSUs (merger related) $34.98; July 2009 – RSUs (under SunShare 2012) $29.96; Options under the Petro-Canada Stock Option Plan $5.64; PSUs under the Petro-Canada Performance Share Unit Plan $15.75. The grant date fair value for compensation purposes is calculated using Towers Watson's binomial option pricing methodology which is fundamentally similar to the methodology used to determine the accounting fair value. In particular, the regular option value is similar under both approaches due to relatively consistent underlying assumptions (e.g., historical volatility, risk-free rate, expected option life). The difference in the value of a SunShare option reflects a discount under Towers Watson's binomial methodology to reflect the performance features attached to these options. The HR&CC uses the binomial option pricing methodology valuations in making its decisions regarding long-term incentive grant levels since it is applied consistently in its consultant's competitive market analyses.

Retirement Arrangements

Suncor Retirement Arrangements. The Suncor Energy Pension Plan is a registered pension plan that provides retirement income to Suncor employees, including Messrs. George, Demosky, Alley and Williams. Retirement income is based on a combination of a defined benefit pension payment, including an employee-paid benefit feature, and a defined contribution account balance.

In addition to the pension under the Suncor Energy Pension Plan, executive officers may receive supplemental retirement payments under the terms of the Supplemental Executive Retirement Plan ("SU SERP"). Under the terms of the SU SERP, any new participants must be approved by the HR&CC, which consists entirely of independent members of the Board of Directors.

The SU SERP is a non-registered supplemental retirement arrangement designed, in conjunction with the registered plan, to attract and retain mid-career executives with a competitive career-based pension that features an up-front accrual balanced by a cap and a 5 year vesting period.

•
  The executive's pension is based on the executive's remuneration times a combined accrual rate of 5% times the number of years of executive employment plus the Suncor Energy Pension Plan defined benefit pension formula percentage (1% per year times the number of years of credited service) relating to credited service prior to becoming an executive, limited to a

26 SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR

combined maximum 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 credited service.

•
  Credited service commences at the date of entry into the Suncor Energy Pension Plan and includes executive employment. Executive employment commences at the date of entry into the SU SERP. Generally, there is no recognition of credited service for non-Suncor related employment.
•
  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.
•
  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 SU SERP to vest. Executive officers with less than five years of executive employment are not eligible to receive supplemental retirement payments under the SU SERP except in the event of a change in control, or a loss of employment upon or after the occurrence of certain specified events.
•
  SU SERP payments for retirement prior to age 60 will be reduced by 5/12th of 1% for each month that the executive officer retires before age 60; no reduction is applied for retirement after age 60.
•
  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; for single employees, for life, with five 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 SU 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 SU SERP obligations.

Petro-Canada Retirement Arrangements. The Petro-Canada Retirement Plan is a registered pension plan that provides retirement income to certain Suncor employees that worked for Petro-Canada prior to the merger, including Messrs. Brenneman, Roberts and Jackman. Retirement income is based upon a defined contribution account balance as set out in the description of the Defined Contribution Plans. The defined benefit provision of the Plan has been closed to new entrants since July 1, 1996; some of the Named Executive Officers continue to participate in this portion of the plan.

In addition to the pension under the Petro-Canada Retirement Plan, executive officers may receive supplemental retirement payments under the terms of a supplemental executive retirement plan ("PC SERP") or individual Retiring Allowance Agreements as follows:

•
  Mr. Brenneman is covered by the PC SERP and by the Petro-Canada Retirement Plan (defined contribution provision).
•
  Messrs. Roberts and Jackman are covered by individual retiring allowance agreements and by the Petro-Canada Retirement Plan (defined benefit provision).

The normal retirement benefit is (a) Mr. Brenneman – 1.5% per year of credited service multiplied by the average of the highest 36 consecutive months of the sum of base salary plus annual incentive in the final 120 months of service reduced by his Defined Contribution benefit; and, (b) Messrs. Roberts and Jackman – 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 the PC SERP and the individual retirement allowance agreements require 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. Brenneman to 100% of the Consumer Price Index, subject to a maximum indexing adjustment of 2% for any year; and for Messrs. Roberts and 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 is for (a) Mr. Brenneman – married employees, joint and survivor, with 60% to the non-member surviving spouse; for single employees, for life with 10 years guaranteed; (b) Messrs. Roberts and Jackman – married employees, joint and survivor, with 50% to the non member surviving spouse; subject to a minimum of 60 monthly payments.

Mr. Kallos is covered under the Petro-Canada UK Pension Plan, a closed registered pension plan (defined benefit) that was available prior to January 2007 to Petro-Canada's permanent UK employees. Upon reaching the lifetime limit on pension value that is tax preferred, Mr. Kallos had the option of electing to receive a cash allowance equal to 25% of his basic salary in lieu of continued pension plan coverage. Mr. Kallos has elected to continue his participation in the registered pension plan.

SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR 27

The normal retirement benefit for Mr. Kallos is 1/54 per year of service, to a maximum of 36 years, multiplied by the highest basic salary at any time during his final 10 years of service less an amount equal to the basic state pension for a single person at the time of retirement. Mr. Kallos contributed 4% of basic salary in excess of the basic state pension for a single person to the pension plan. Early retirement is permitted after age 55 with our consent or after age 60 without our consent. In the event of early retirement before age 60, the normal retirement benefit is reduced on a basis certified as reasonable by the Scheme Actuary; no reduction is applied for early retirement after age 60. In the event of the death after retirement, 66.66% of the retirement benefit will be continued for the life of his spouse and 33.33% to his dependent children for as long as the children meet the eligibility requirements.

(1)
  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 at December 31, 2009.
(2)
  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; 5 years of industry service granted to Mr. Brenneman over his first 5 years of service; 10 years of industry service granted to Mr. Jackman at date of hire; and, 5 years of industry service granted to Mr. Roberts at January 20, 2000.
(3)
  Mr. Alley retired on January 3, 2010 and Mr. Kallos elected to leave the company on December 31, 2009.
(4)
  The accrued 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 pension liabilities as disclosed by each predecessor company or Suncor, as applicable, in the consolidated financial statements. 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.
(5)
  Compensatory change represents the increase in the pension liability for 2009 related to the annual service cost, compensation changes higher (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.
(6)
  Includes items such as interest on the obligation and the impact of changes in the discount rate assumption.
(7)
  Mr. Brenneman's defined benefit obligation has been restated from the prior year by removing his defined contribution benefit and including it under the Defined Contribution Plans.
(8)
  Mr. Demosky's credited service reflects his executive employment plus 3 years of service accrued under the Suncor Energy Pension Plan prior to becoming an executive.
(9)
  For Mr. Demosky, the amount represents the total pension accrued under SERP. Only a portion of this benefit relating to the registered and supplemental plans is vested at December 31, 2009.
(10)
  Includes an additional 24 months of service granted to Mr. Kallos, who elected to leave the company. The pension benefit relating to this additional service including 24 months of employee contributions to the plan are included herein. All benefit, and service cost data plus the accrued obligation at December 31, 2009 for Mr. Kallos are converted from British pounds to Canadian dollars using the exchange rate at December 31, 2009 (1.7113; 2008 – 1.7896).

Defined Contribution Plans. Under the Suncor Energy Pension Plan, applicable to Messrs. George, Demosky, Alley and Williams, 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.

Under the Petro-Canada Retirement Plan, Suncor makes contributions to the Defined Contribution Accounts for employees participating in the Defined Contribution provision, including Mr. Brenneman, of between 5% and 8% of earnings, subject to maximum contribution levels, depending upon an employees' length of service with the Suncor. Based upon his service, Suncor made contributions in 2009 on behalf of Mr. Brenneman at a rate of 6%.

Under both plans, 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.

TERMINATION CONTRACTS AND CHANGE OF CONTROL ARRANGEMENTS

Suncor Termination Contracts. Suncor has entered into termination contracts with each of the pre-merger Suncor Named Executive Officers to compensate such individuals, based on their remuneration, in the event of termination ("Termination Event") by Suncor, other than for just cause, and by the Named Executive Officer within 120 days following a constructive dismissal event, which includes a significant adverse change in their compensation, a significant diminution in their duties or responsibilities, certain relocations, or other material adverse changes to the terms of their employment.

In 2008, the HR&CC reviewed the termination contracts in light of market trends and reduced, on a go forward basis, the notice period for executive termination contracts. As a result, should a Termination Event occur, the termination contracts provide a 24-month notice period for Mr. Demosky and a 30-month notice period for the remaining pre-merger Suncor Named Executive Officers. Cash payments are provided for annual remuneration during the notice period, for 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. Unless the Named Executive Officer is an eligible retiree, unvested options and share units granted under the SunShare 2012 Plan are, respectively, cancelled and forfeited. Named Executive Officers receive credited service under the SU SERP for the notice period.

Petro-Canada Termination Contracts. Termination Contracts held by pre-merger Petro-Canada executives continuing with Suncor have been carried forward and will be reviewed by the Board of Directors in the spring of 2010. Contracts with the Named Executives Officers from pre-merger Petro-Canada provide for a lump sum payment equal to base salary as of the date of termination, annual incentives and for Mr. Brenneman, the value of mid- or long-term incentives that may have been granted over the notice period. For Messrs. Jackman and Roberts the value of mid- or long-term incentives considered in the termination agreement is the lesser of the value of the grant of options to the Executive in February 2000 and the value of the options granted to the Executive in 2001 and in each successive year thereafter. The notice period for Mr. Brenneman is the lesser of three years or 65 minus his age; given Mr. Brenneman's age, his notice period as at December 31, 2009 was approximately 1.5 years. The notice periods for Messrs. Jackman and Roberts is the lesser of 2.5 years or 65 minus his age. For the purpose of calculating the Named Executive Officer's retirement benefit, service is increased by the notice period and the executive is deemed to have earned the base salary as of the termination date for the duration of the notice period. The notice period for Mr. Kallos was 2 years.

Change in Control. Stock options under the SOP, ESP, Key Contributor Plan and SunShare 2012 Plan (collectively, the "Suncor Plans"), that are granted but not yet exercisable, become immediately exercisable in the event of a change of control of Suncor. In addition, PSUs and RSUs will vest in the event of a change of control subject to Suncor performance measured at the change of control date. Under the SOP, 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. None of the pre-merger Petro-Canada executives have a change of control clause in their respective Termination Contract.

Executive officers with less than five years of executive service may become eligible to receive supplemental retirement payments under the SU SERP in the event of a change in 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 SU SERP upon a change in control of Suncor.

Limited Appreciation Rights. Certain management and key employees including Named Executive Officers, have LARs attached to their options. LARs provide the holders an opportunity to realize the value, if any, of their options under the Suncor Plans upon occurrence of a change of control (as explained above) transaction affecting Suncor. In that circumstance, option holders may be unable to exercise their options prior to completion of a change of control transaction due to securities regulatory requirements or internal Suncor policies.

SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR 29

LARs represent a right attached to each option held by the LARs holder, exercisable upon completion of a change of control transaction, to receive a cash payment from Suncor, upon surrender of a related option. The cash payment for all LARs holders, other than U.S. taxpayers, is equal to the amount, if any, by which:

(a)
  the greater of,
  (i)
    the highest price per Suncor common share paid by a person acquiring Suncor common shares in the change of control transaction, and
  (ii)
    the highest daily trading price of the Suncor common shares on the TSX during the 60-day period preceding the date of the change of control transaction (daily trading price for this purpose means the average of the high and low board lot trading prices of the Suncor common shares on any particular day),
(b)
  exceeds the exercise price of the option to which the LAR is related.

LARs are 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 held by the holder during the term of the LAR. Upon the exercise or expiry of any option, the attached LAR is cancelled.

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 of Directors has the discretion to permit the exercise of LARs in the manner and on such terms as it may authorize.

Total |  | 71 941 308 |  | 32.24 |  | 23 875 540 |

The numbers shown under "Option plans approved by security holders" refer to the SOP, ESP, the SunShare Performance Stock Option Plan, the Petro-Canada Employee Stock Option Plan and the SunShare 2012 Plan. The numbers shown under "Option plans not approved by security holders" refer to the Key Contributor Stock Option Plan, which was approved by the Board of Directors in 2004 and closed effective July 31, 2009.

Suncor Energy Stock Option Plan. The Suncor Energy Stock Option Plan ("SOP") provides for the grant of options to purchase Suncor common shares, as well as the grant of SARs and LARs.

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 have a term of seven years. A Tandem SAR 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 is the simple average of the high and low prices at which shares were traded in one or more board lots on the TSX on the day prior to the grant date.

Effective August 1, 2009, the SOP provided for the reservation of 45,845,554 shares which could be issued pursuant to the exercise of options which are granted under, or otherwise subject to, the SOP. This reservation consisted of the aggregate of (i) 29,903,173 common shares which would otherwise be reserved for issuance under the PC SOP pursuant to the exercise of Petro-Canada options issued under the PC SOP outstanding as at August 1, 2009, and (ii) the re-allocation to the SOP of 15,942,381 common shares that would otherwise be unallocated and reserved and available for issuance pursuant to the exercise of unallocated options under the pre-merger Suncor incentive plans that were closed to new grants effective August 1, 2009 (see "Suncor Closed Plans" for more information).

Performance Share Unit Plan. PSUs pay out at a value between 0% and 150% (for grants prior to January 1, 2010) or 0% and 200% (for grants after January 1, 2010) of face value contingent upon Suncor's performance relative to a peer group of companies over a three year period. The peer group is chosen based on criteria approved by the HR&CC. Specifically, the peer group for grants prior to January 01, 2010 includes large oil and gas production companies in Canada and the United States and all Canadian integrated oil and gas companies. The peer group for grants after 2010 includes North American and International Energy companies. The peer group is adjusted as appropriate and approved by the HR&CC for each annual grant. The 2006 PSU grants for both pre-merger Suncor and Petro-Canada did not meet minimum thresholds to pay out.

Performance and the corresponding payout, if any, is measured by reference to Suncor's total shareholder return ("TSR") relative to its peer group. The PSU Plan was amended in 2009 to provide for dividend reinvestment for grants after January 1, 2010.

SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR 31

Vesting for grants of PSUs up to and including the 2007 grant occurs as follows:

Percentage of PSU 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% |  | Suncor TSR greater than or equal to the 25th percentile of the peer group TSRs, and less than the 50th percentile of the peer group TSRs. |
100% |  | Suncor TSR greater than or equal to the 50th percentile of the peer group TSRs, and less than the 75th percentile of the peer group TSRs. |
150% |  | Suncor TSR greater than or equal to the 75th percentile of the peer group TSRs. |

Vesting for grants of PSUs awarded after January 1, 2008 was changed to more explicitly recognize performance between the 25th and 75th percentiles of the peer group occurs as follows (as approved by the Board on July 24, 2008):

Percentage of PSU 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 150% |  | Suncor TSR greater than or equal to the 25th percentile of the peer group TSRs, and less than the 75th percentile of the peer group TSRs. |
150% |  | Suncor TSR greater than or equal to the 75th percentile of the peer group TSRs. |

Vesting for grants of PSUs awarded after January 1, 2010 was changed to a maximum payout of 200% of target as follows (as approved by the Board on November 13, 2009):

Percentage of PSU 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% |  | Suncor TSR greater than or equal to the 25th percentile. |

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.

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.

Restricted Share Unit Plan. The RSU Plan was established in January 2009 by the HR&CC and is designed, in light of existing market conditions, to provide RSUs to key employees, senior managers and executives of Suncor as part of their annual equity-based 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 will 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 dividend reinvestment for grants after January 1, 2010.

  Option grants may include associated LAR.
(2)
  Unless otherwise indicated date shown is period of time from grant date.
(3)
  100% of options vested in recognition of the performance criteria described in footnote 4.
(4)
  The performance criteria for maximum vesting included achievement of Suncor-wide targets for return on capital employed ("ROCE") with maximum vesting at 15% average annual ROCE over the 2003 to 2008 period, and a doubling of share price from the $13.82 grant price by April 2008 (achieved June 2005). The interim targets, namely the achievement of a 40% rise in share price concurrent with TSR superior to the TSR of the S&P 500, and the achievement of 15% ROCE for 2003 to 2004, were achieved on October 5, 2004 and December 31, 2004 respectively.
(5)
  On May 12, 2008 we achieved the first share price target of the SunShare 2012 Plan. See footnote 6 for details.
(6)
  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.

  The PCSAR Plan provides a cash payment to participants equal to the appreciation in Petro Canada's 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 Compensation Committee in its discretion at the time the SARs are 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 SARs are granted.
(2)
  PSUs under the PCPSU are a form of mid-term incentive that rewards participants for Petro Canada's performance against specific performance standards. The Compensation Committee used its discretion to select and attach performance standards to PSUs. Relative Total Shareholder Return ("PCTSR") is the measure that was employed from 2004.
(3)
  This plan closed on December 31, 2003.
(4)
  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.

•
  The SOP and the Suncor Closed Plans contain an amendment provision providing that the Board may amend, modify or terminate the plans if and when it is advisable at the discretion of the Board without disinterested shareholder approval except for those amendments specifically requiring disinterested 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; (c) an amendment that extends the term of an award beyond its original expiry that benefits any option holder; (d) allowing awards granted under the plans to be transferable or assignable other than for normal estate settlement purposes; (e) any amendment to the definition of participant or eligible participant that may permit the introduction of non-employee directors on a discretionary basis.
•
  The Petro-Canada Stock Option Plan 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 a resolution of the option holders or passed at a meeting of option holders.
•
  No one person or company is entitled to receive more than 5% of the common shares reserved for issuance on exercise of the options available for grant under the SOP and the Suncor Closed Plans.
•
  All or any portion of an option or LAR granted under any of these 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. 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 SOP and the Suncor Closed Plans cannot be less than the fair market value of a common share at the time of grant.

•
  Options granted under the SOP and the Suncor Closed Plans, but not yet exercisable, become immediately exercisable in the event of a change of control of Suncor.
•
  The SOP and the Suncor Closed Plans 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 the Suncor Closed Plans, under any employee stock purchase plans of Suncor 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 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) 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 or disability and no later than three years after termination of employment due to retirement. In the event of involuntary termination for cause, all options expire on the date of such termination.
•
  Pursuant to the ESP and the Key Contributor Plan, 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 one year after termination of employment due to death or disability and no later than three years after termination of employment due to retirement.
•
  Pursuant to the SunShare Plan and 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 SunShare Plan, upon retirement or disability, options vest on a pro-rated basis, based on active service and achievement of performance criteria and expire one year from date of vesting. Pursuant to the SunShare 2012 Plan, upon retirement or disability, options may vest on a pro-rated basis based on active service. Any options that have not vested within one year of retirement shall be cancelled and be of no further force and effect.

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 2009, Suncor paid premiums of approximately US$1.5 million for directors and officers insurance for the 12-month period ending August 1, 2010.

CORPORATE GOVERNANCE

Suncor's Board of Directors 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 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 2009 did not differ from the NYSE Standards in any significant respect, with the exceptions described in Schedule D 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 (collectively, the "CSA Guidelines"). This Statement has been approved by the Board of Directors, on the recommendation of its Governance Committee.

Suncor's Statement can be found in Schedule D.

Statement of Corporate Governance Practices

Throughout this Statement of Corporate Governance Practices, there are references to information available on Suncor's website. All such information is available at www.suncor.com under the "Investor Centre" tab. Information on Suncor's website, though referenced herein, does not form part of this Statement or this Information Circular. In addition, shareholders may request printed copies of these materials by contacting Suncor at 112 - 4th Avenue S.W., Calgary, Alberta, T2P 2V5, by calling 1-800-558-9071, or by email request to info@suncor.com.

Board of Directors and Director Independence (1)

The cornerstone of Suncor's governance system is its Board of Directors, whose duty is to supervise the management of Suncor's business and affairs.

The Board is currently comprised of a majority of independent directors (13 of 14 members) (2). The only Suncor director who is not independent is Richard L. George, Suncor's president and chief executive officer ("CEO"). (3) A short biography of each Suncor director can be found starting on page 6.

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. In general terms, the Board considers a director to be independent if that director has no material relationship with the Corporation, either as partner, shareholder or officer of an organization that has a relationship with Suncor. 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 35 of this Information Circular). The independence criteria are set out in Schedule G.

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 immediate family members or as a partner, significant 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.

Some Suncor directors sit on the boards of other public companies. Particulars are set out in the biographies on pages 6 to 9. (4) Some of these are 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, 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 absent themselves from the boardroom and do not participate.

All of the Board's four standing committees – Governance, Audit, Human Resource and Compensation ("HR&CC") and Environment Heath, Safety and Sustainable Development ("EHS&SD") – are comprised entirely of independent directors. 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, as defined below, in Schedule E.

Suncor's independent directors meet in camera at the beginning and end of each Board meeting without management present. Mr. George, 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 Mr. Ferguson, Suncor's independent chairman since April 2007. (5) 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 other independent director. For information about the number of Board and Board committee meetings held during 2009, and directors' attendance at these meetings, see page 10. (6,7)

The roles and responsibilities of Suncor's independent chairman are set forth in a position description that has been approved by the Board. The position description is set out in Schedule F. (8)

SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR 45

Board Mandate (9)

The Board has developed terms of reference ("Terms of Reference") as the charter of the Board. 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 ("Board Mandate") that describes its major responsibilities, goals and duties. The Board of Directors has approved and reviews at least annually its Terms of Reference. These 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. 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 E.

The Board of Directors delegates day-to-day management of Suncor's business to Suncor's CEO and other members of 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 in the best interests of Suncor. A management control process policy, adopted by the Board, defines and sets limits on the authority delegated to management.

The following is a description of some key duties of the Board as set out in the Board Mandate, with reference to the Canadian Requirements, including a description of the specific roles of Board committees. The following description is not exhaustive. For more information, please refer to Schedule E and to the mandates of Suncor's Board committees, available on Suncor's website.

Ethics (10) The Board Mandate explicitly recognizes that the Board, through the CEO, sets Suncor's standards of conduct, including our general moral and ethical tone, standards for compliance with applicable laws, standards for financial practices and reporting, qualitative standards for operations and products, and others. The Board Mandate also states the Board should be satisfied that the CEO and executive officers are creating and fostering a culture of integrity within Suncor. The Board plays an active role in this area through its oversight of Suncor's business conduct code and compliance program (see "Ethical Business Conduct" on page 49), and through its assessment and evaluation of the performance of the CEO. The CEO's position description includes an accountability for setting a high ethical tone for the organization as a whole and fostering a culture of integrity throughout the organization (see "Position Descriptions" on page 49).

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 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.

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. To that end, the Board undertakes an annual principal risk review. This includes an identification, classification and assessment of the principal risks of our business and an overview of risk management and mitigation strategies. Each principal risk is mapped to a Board committee, or the full Board as appropriate, for oversight, and to the CEO and other members of senior management with the key accountability in each risk area. The Audit Committee oversees the Board's risk management governance model by conducting periodic reviews to reflect the principal risks of our business in the mandates of the Board and its committees. For example, the EHS&SD Committee monitors the effectiveness and integrity of Suncor's internal controls as they relate to operational risks of its physical assets. It also reviews environmental, health and safety and sustainable development issues and reports to the Board of Directors on these matters. The Audit Committee reviews financial risk management issues, programs and policies, including cash management, insurance and the use of financial derivatives. The Governance Committee assists the Board by reviewing and assessing emerging risk areas that do not fall under the mandate of another Board committee.

Succession Planning and Monitoring/Evaluating Senior Management The Board ensures the continuity of executive management by appointing a CEO and overseeing succession planning for that key role. 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 are in place and operating effectively. The HR&CC also reviews and reports to the Board on the succession plan and succession planning process for senior management positions, including the position of CEO. The HR&CC conducts an annual review of the CEO's performance against predetermined goals and criteria, and recommends to the Board the total compensation of the CEO (see "Compensation Discussion and Analysis" on page 12).

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

46 SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR

code (see the information under the heading, "Ethical Business Conduct", on page 49) 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 our 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.

The Board of Directors is specifically mandated to ensure systems are in place for communication with Suncor's shareholders and other stakeholders. 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.

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 control and management information systems. The Audit Committee is specifically mandated to assist the Board of Directors by reviewing the effectiveness of financial reporting, management information and internal control systems and the effectiveness of management in ensuring the integrity and security of Suncor's electronic information systems and records. This includes a review of the evaluation of these systems by internal and external auditors.

Corporate Governance System The Governance Committee assists the Board of Directors with governance issues. Among other things, this committee monitors and reviews key corporate governance requirements, guidelines and best practices, making recommendations to the Board where appropriate, and reviews and approves this Statement of Corporate Governance Practices (See "Governance Committee", under the heading "Board Committees" below).

Stakeholder Feedback The Board Mandate currently provides that the Board should ensure Suncor has systems in place to accommodate stakeholder feedback, and that these systems are appropriately resourced. Among other feedback mechanisms, Suncor currently maintains a 1-800 phone number as well as email and regular mail addresses for stakeholder feedback and questions. Shareholders may communicate directly with Suncor's independent chairman by addressing correspondence to him at the address set out on page 45.

Expectations and Responsibilities of Directors The Terms of Reference, supplemented by a Board-approved accountability statement for directors, 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. Directors must devote sufficient time and energy to their role as Suncor director to effectively discharge their duties to Suncor and the Board. Board meeting dates are established well in advance and directors are expected to attend all meetings absent extenuating circumstances. Directors' attendance records for meetings held in 2009 are set out on page 10.

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.

Board Committees (11)

The Board of Directors discharges its responsibilities through preparation for and attendance at regularly scheduled meetings, and through its four standing committees, each of which has a written mandate that is reviewed annually by such committee. 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.

The following is a brief summary of the key functions, roles and responsibilities of Suncor's Board committees. The complete text of the mandates of each Board committee is on Suncor's website.

Governance Committee The Governance Committee assists the Board in two 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. It also reviews matters pertaining to Suncor's values, beliefs and standards of

SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR 47

ethical conduct and Suncor's corporate reputation. The Governance Committee also conducts an annual assessment of the overall performance and effectiveness of the Board of Directors, its committees and individual directors and annually reviews and makes recommendations to the Board on the competitiveness and form of the Board of Directors' compensation and share ownership guidelines.

In its strategy role, the Governance Committee acts as an effective sounding board for management on key strategic initiatives and reviews and assesses processes relating to long-range and strategic planning and budgeting.

Audit Committee The Audit Committee assists the Board in matters relating to Suncor's internal controls and internal auditors, excluding the operations integrity audit department which is specifically within the mandate of the EHS&SD Committee (references throughout this Schedule D to "Internal Audit" shall not include the operations integrity audit department). The Audit Committee also assists in matters relating to 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.

In fulfilling its role, the Audit Committee monitors the effectiveness and integrity of Suncor's financial reporting, management information and internal control systems. 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 chief officer 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. It also reviews any recommended appointees to the office of chief financial officer. The Audit Committee also monitors Suncor's business conduct code compliance program (see "Ethical Business Conduct" on page 49).

The Audit Committee plays a key role in relation to Suncor's external auditors. It initiates and approves their engagement 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 annually approves the appointment and terms of engagement 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 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 and investment strategy of Suncor's registered pension plan, as well as the terms of engagement of the plan's actuary and fund manager, and any significant actuarial reports. The Audit Committee oversees generally the Board's risk management governance model by conducting periodic reviews to ensure the principal risks of Suncor's business are reflected in the mandates of the Board and its committees, and reviews significant physical security management, IT security or business recovery risks and strategies to address such risks.

For additional information about Suncor's Audit Committee, including the Audit Committee Charter and Pre-approval Policies and Procedures, see "Audit Committee Information" in Suncor's Annual Information Form dated March 5, 2010, 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 reviews quarterly management stewardship reports as well as the findings of significant external and internal environmental, health and safety ("EH&S") 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 EH&S, and reviews the results of evaluations of internal controls by the operations integrity auditors. In fulfilling this role, it reviews and approves the appointment or termination of the Director, Operations Integrity Audit, and reviews the qualifications of the

48 SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR

internal auditors and organizational structure of the Operations Integrity Audit department. The EHS&SD Committee also reviews the department's charter and its annual audit plans and activities, and the effectiveness of the operations integrity audit function. The EHS&SD Committee approves the engagement or termination of external auditors overseeing the operations integrity audit program, and reviews their audit scope, approach and performance, and approves their fees.

Human Resources and Compensation Committee For more information regarding the nature, scope, roles and responsibilities of the HR&CC, see "Compensation Discussion and Analysis", starting on page 12.

Position Descriptions (12)

The Board has developed and approved written position descriptions for the Board chairman, Board committee chairs and the CEO. The Board has also developed and approved a written position description, called an "Accountability Statement", for individual directors. For a summary of individual director accountabilities, see "Expectations and Responsibilities of Directors", under the heading "Board Mandate" on page 46. The position description for the CEO 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.

The position descriptions form part of the charter of the Board of Directors, and as such are reviewed annually by the applicable Board committee and changes are recommended by that committee to the full Board. The position descriptions are all posted on Suncor's website. In addition, the position description for Suncor's Chairman of the Board is set out in Schedule F.

Orientation and Continuing Education (13)

Each new member of the Board will participate 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 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. (14)

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 acquainting directors with Suncor's operations and the communities in which they are located.

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

The Governance Committee maintains a 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. (15) 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.

Ethical Business Conduct (16)

Code of Conduct Sound, ethical business practices are fundamental to Suncor's business. Suncor has a business conduct code (the "Code") that applies to Suncor's directors, officers, employees and contractors. (17) The Code 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, fair dealing in trade relations, and accounting, reporting and business control. Suncor's Code is supported by detailed policy guidance and standards, and a Code compliance program, under which every Suncor director, officer, non-union employee and independent contractor is required annually to complete training on the Code and certify that he or she has reviewed the Code, that he or she understands the requirements of the Code, and his or her compliance with the Code during the preceding 12-month period.

Suncor's Board exercises stewardship over the Code in several respects. Suncor's internal auditors audit the compliance program annually, and the director of internal audit, who has direct reporting relationships with the Audit Committee, reports on compliance to that committee. In addition, at least once annually, the Code is reviewed and if appropriate, updated. Management reports to the Governance Committee annually on this process, and any recommended changes are approved by the Governance Committee. (18) Any waivers of Code requirements for Suncor's executive officers or members of the Board of

SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR 49

Directors must be approved by the Board of Directors or appropriate committee thereof, and disclosed. No such waivers were granted in 2009.

Suncor encourages employees to raise ethical concerns with Suncor management, our legal, corporate security, human resources or internal audit departments, without fear of retaliation. In addition, the Board has established an "Integrity Hotline" to provide a means for Suncor employees to discuss 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.

The Code is available on Suncor's website, under the "Governance" tab in the Investor Centre. (19)

Conflicts of Interest (20)

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 Board chair, 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 Board chair or the Governance Committee chair. The director's conflict or potential conflict is recorded in the minutes of 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.

Nomination of Directors (21)

The selection process for new nominees for membership on Suncor's Board of Directors is conducted by the Governance Committee, which is comprised solely of independent directors. (22) More information on the responsibilities, powers and operations of the Governance Committee is found on page 47. (23)

The Governance Committee maintains an inventory of capabilities, competencies and skills of current Board members and of the Board as a whole. This is periodically assessed to identify any gaps between the desired set of capabilities, competencies, skills and qualities, and those that are adequately represented on the Board, taking pending retirements into account. The Committee uses this assessment as a basis for identifying the skills, experiences, qualifications, diversity and personal qualities desired in potential new Board members. The Governance Committee maintains a list of potential candidates identified from a number of sources, including an executive search firm and 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.

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. (24)

Compensation(25)

Human Resources and Compensation Committee. The HR&CC, comprised entirely of independent directors, assists the Board in matters pertaining to executive compensation.

Governance Committee. The Governance Committee, comprised entirely of independent directors, assists the Board in matters pertaining to Board compensation.

Board Compensation. 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

50 SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR

compensation, and makes recommendations to the full Board on the level and form of Board compensation and share ownership guidelines. The Board has set director compensation based upon recommendations from this committee.

CEO and Senior Executive Compensation. 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 Board chair. 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.

For more information about the HR&CC and the process and criteria for determining the CEO's total compensation, see "Executive Compensation" on page 16.

Assessment of Directors (26)

The Governance Committee annually assesses and evaluates the overall performance and effectiveness of the Board of Directors, its committees, and individual directors, both as directors and as chairs of the Board or a particular Board committee, if applicable. Each year, directors complete a confidential questionnaire that includes both a self-assessment and peer review to assess individual performance. The resulting data is analyzed by the Governance Committee, which then reports to the full Board of Directors with any recommendations for enhancing or strengthening effectiveness. The Board chair reviews data relating to individual performance and conducts one-on-one meetings with each director as appropriate, focused on individual effectiveness.

Compliance with NYSE Standards

Suncor's corporate governance practices meet or exceed all applicable Canadian Requirements and SEC Requirements. Except as disclosed below, Suncor's corporate governance practices are in compliance with NYSE Standards in all significant respects.

•
  Approval of Equity Compensation Plans. The NYSE Standards require shareholder approval of all equity compensation plans and any material revisions thereto, regardless of whether the securities to be delivered under them are newly issued or purchased on the open market. The TSX rules, applicable to Suncor, only require shareholder approval in accordance with a specific amendment provision, as approved by shareholders at the 2010 annual and special meeting and by the TSX. See "Summary of Incentive Plans" on page 31.
•
  Independence Standards. The Board of Directors is responsible for determining whether or not each director is independent. In making this determination, the Board has adopted the definition of "independence" as set forth in Canadian Requirements (specifically National Instrument 52-110 Audit Committees) and SEC Requirements (specifically Rule 10A-3 of the Securities Exchange Act of 1934). Suncor's Board has not adopted the director independence standards contained in Section 303A.02 of the NYSE's Listed Company Manual.

SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR 51

SCHEDULE E: 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 company 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 except in limited and specifically identified circumstances, do not 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.

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, 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 the definition 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.

(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.
•
  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 Company of a culture of integrity.
•
  The 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.

SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR 53

•
  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 HR&CC, 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 HR&CC, and the Environment, Health and Safety Committee ("EH&SC"). 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 determine 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 five 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 directors. In addition, all members of the Audit committee must be, in the judgment of the Board of the Directors, financially literate (3), and at least one member of the Audit Committee must be an audit committee financial expert (4). 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 Company's management proxy circular.
•
  The HR&CC will consist entirely of outside, independent directors.
•
  The Governance Committee shall consist entirely of outside, independent directors.
•
  The Chairman, by standing invitation, is considered an ex-officio of those committees of the Board of which he is not a listed member.

54 SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR

•
  At the conclusion of each committee meeting, the committee shall meet on an "in camera" basis without management. Such in camera meetings shall be presided over by the Chair of the committee, if an independent director, or other committee member who is an independent director, as selected by the independent directors on the committee.

SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR 59

SCHEDULE G: DIRECTOR INDEPENDENCE POLICY AND CRITERIA

Background

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

The purpose of this independence policy and criteria is to state the criteria by which Suncor's Board determines whether each of its directors is or is not independent.

Independence Policy

Pursuant to the terms of reference for Suncor's Board of Directors, a majority of the Board of Directors must be independent, and in addition, the Audit, Governance and HR&C 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 Suncor's 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:

•
  The director is, or has been within the last three years, an employee or executive officer of the corporation, or an immediate family member (1) is or has been within the last three years, an executive officer, of the corporation.
•
  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 the corporation'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 the corporation's audit within that time. For the purposes of this point ONLY, "immediate family member" means only 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, the corporation, 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 the corporation to the organization exceeded the greater of $1 million, or 2% of such organization's consolidated gross reserves.

(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.
•
  For Audit Committee members only, in order to be considered independent, a member of an Audit Committee may not, other than in his or her capacity as a member of the Audit Committee, the Board of Directors 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)

60 SUNCOR ENERGY INC. 2010 MANAGEMENT PROXY CIRCULAR

for prior service with the corporation 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.

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 of Directors 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, 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.
