SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 1

ABOUT THIS MANAGEMENT PROXY CIRCULAR

You are invited to attend the annual general meeting of shareholders of Suncor Energy Inc. to be held in the Telus Convention Centre, 120 Ninth Avenue SE, Calgary, Alberta, on April 28, 2016, at 10:30 a.m. Mountain Daylight Time ("MDT") for the purposes indicated in the Notice of Annual General Meeting.

Suncor's management proxy circular includes important information regarding the matters to be acted upon at the annual general meeting, and our compensation practices for and compensation of the board of directors of Suncor (the "Board" or "Board of Directors") and Suncor's Named Executive Officers (as defined on page 26) for the year ended December 31, 2015.

This management proxy circular is dated February 25, 2016, and all information contained in this management proxy circular is given as of such date, unless stated otherwise.

In this management proxy circular, references to "Suncor", the "Corporation", the "company", "our" or "we" mean Suncor Energy Inc., its subsidiaries, partnerships and joint arrangements, unless the context otherwise requires.

Forward-Looking Information and Risks This management proxy circular contains forward-looking information based on Suncor's current expectations, estimates, projections and assumptions. This information is subject to a number of risks and uncertainties, including those discussed in Suncor's Annual Information Form for the year ended December 31, 2015 (the "AIF"), Suncor's Management's Discussion and Analysis for the year ended December 31, 2015 (the "MD&A"), and Suncor's other disclosure documents, many of which are beyond the company's control. Users of this information are cautioned that actual results may differ materially. Refer to the "Advisories" section of this management proxy circular for information on the material risk factors and assumptions underlying our forward-looking information. The company's financial and operational performance is potentially affected by a number of factors, including but not limited to, the factors described in the "Advisories" section of this management proxy circular. Non-GAAP Financial Measures Certain financial measures in this management proxy circular – namely operating earnings, cash flow from operations ("CFOPS"), return on capital employed ("ROCE") and Oil Sands cash operating costs – are not prescribed by generally accepted accounting principles ("GAAP"). Refer to the "Advisories" section of this management proxy circular. These non-GAAP financial measures are included because management uses the information to analyze business performance, leverage and liquidity. These non-GAAP financial measures do not have any standardized meaning and therefore are unlikely to be comparable to similar measures presented by other |  | companies. Therefore, these non-GAAP financial measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. Measurement Conversions Suncor converts certain natural gas volumes to barrels of oil equivalent ("boe") on the basis of one barrel ("bbl") for every six thousand cubic feet ("mcf") of natural gas. Any figure presented in boe may be misleading, particularly if used in isolation. A conversion ratio of six mcf of natural gas to one bbl of crude oil is based on an energy equivalency conversion method primarily applicable at the burner tip and does not necessarily represent a value equivalency at the wellhead. Given that the value ratio based on the current price of crude oil as compared to natural gas is significantly different from the energy equivalency of 6:1, conversion on a 6:1 basis may be misleading as an indication of value. In this management proxy circular, references to "mbbls/d" mean thousands of barrels per day and "mboe/d" mean thousands of barrels of oil equivalent per day. Website References Information contained on or otherwise accessible through Suncor's web site and other web sites, though referenced herein, does not form part of and is not incorporated by reference into this management proxy circular.

Q. Am I entitled to vote?

A. You are entitled to vote if you are a holder of Suncor common shares as of the close of business on March 2, 2016, the record date for the meeting. Each Suncor common share is entitled to one vote. A simple majority of votes (50% plus one vote) cast at the meeting in person or by proxy is required to approve all matters. The list of registered shareholders maintained by Suncor will be available for inspection after March 2, 2016, during usual business hours at the offices of Computershare, 600, 530 – 8th Avenue SW, Calgary, Alberta, T2P 3S8 and will be available at the meeting.

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

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

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 3

Q. How can I vote?

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

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

Q. How can a non-registered shareholder vote?

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

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

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

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

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

The shares represented by your proxy must be voted or withheld from voting 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 or withheld from voting as your proxyholder sees fit. Unless contrary instructions are provided, shares represented by proxies received by management will be voted:

•
  FOR the election of the director nominees set out in this management proxy circular;
•
  FOR the re-appointment of PricewaterhouseCoopers LLP as auditors;
•
  FOR the approach to executive compensation disclosed in this management proxy circular;
•
  FOR Shareholder Proposal No. 1 set forth in Schedule A regarding ongoing reporting on Suncor's initiatives respecting climate change; and
•
  AGAINST Shareholder Proposal No. 2 set forth in Schedule B regarding annual disclosure by Suncor of lobbying-related matters.

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

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

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

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

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

Q. Can I revoke a proxy or voting instruction?

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

1.
  completing and signing a proxy bearing a later date, and delivering it to Computershare; or
2.
  delivering a written statement, signed by you or your authorized attorney to:
  (a)
    the Corporate Secretary of Suncor Energy Inc. at P.O. Box 2844, 150 – 6th Avenue S.W., Calgary, Alberta, T2P 3E3 at any time up to and including the last business day prior to the meeting, or the

business day preceding the day to which the meeting is adjourned or postponed; or

(b)
  the chair of the meeting prior to the start of the meeting.

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

Q. Is my vote confidential?

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

Q. How many common shares are outstanding?

A. As of February 22, 2016, there were 1,544,964,541 common shares outstanding. We have no other class or series of voting shares outstanding.

As of February 22, 2016, there was no person who, to the knowledge of our directors and executive officers, beneficially owned, or controlled or directed, directly or indirectly, common shares carrying 10% or more of the voting rights attached to all outstanding common shares.

Q. How will meeting materials be delivered?

A. We are using notice and access to deliver this management proxy circular to both our registered and non-registered shareholders. This means that Suncor will post the management proxy circular on line for our shareholders to access electronically. You will receive a package in the mail with a notice (the "Notice") outlining the matters to be addressed at the meeting and explaining how to access and review the circular electronically, and how to request a paper copy at no charge. You will also receive a form of proxy or a voting instruction form in the mail so you can vote your shares. All applicable meeting related materials will be indirectly forwarded to non-registered shareholders at Suncor's expense.

Notice and access is an environmentally friendly and cost effective way to distribute the management proxy circular because it reduces printing, paper and postage.

Q. How can I request a paper copy of the management proxy circular?

A. Both registered and non-registered shareholders can request a paper copy of the management proxy circular for up to one year from the date it is filed on SEDAR (www.sedar.com). The management proxy circular will be sent to you at no charge. If you would like to receive a paper copy of the management proxy circular, please follow the instructions provided in the Notice. If you request a paper copy of the management proxy circular, you will not receive a new form of proxy or voting instruction form, so you should keep the original form sent to you in order to vote.

Suncor will provide paper copies of the management proxy circular to shareholders who have standing instructions to receive, or for whom Suncor has otherwise received a request to provide, paper copies of materials.

If you have any questions about notice and access, you can call our Investor Relations line at 1-800-558-9071.

Q. What is electronic delivery?

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

Q. How can I ask for electronic delivery?

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 5

BUSINESS OF THE MEETING

Financial Statements

The audited consolidated financial statements for the year ended December 31, 2015 and the report of the auditors thereon will be placed before the meeting. These audited consolidated financial statements form part of our 2015 Annual Report. Copies of the 2015 Annual Report may be obtained from the Corporate Secretary upon request and will be available at the meeting. The full text of the 2015 Annual Report is available on Suncor's web site at www.suncor.com and has been filed with the Canadian securities regulatory authorities and the U.S. Securities and Exchange Commission.

Election of Directors

Number of Directors. Suncor's articles stipulate there shall be not more than 15 nor fewer than eight directors. The Board is currently composed of 12 non-employee directors, including James W. Simpson, our Board chair, and one member of management, Steven W. Williams, our President and Chief Executive Officer ("CEO").

W. Douglas Ford will be retiring from the Board this year and will not stand for re-election. Mr. Ford has provided Suncor with 12 years of service and has made a significant contribution to Suncor's success through his sound business acumen and dedication during his tenure. Suncor's Board and management wish to thank Mr. Ford for his service to Suncor and its shareholders.

In accordance with our by-laws, the Board has determined that 12 directors will be elected at the meeting. Following the annual general meeting, and assuming that all proposed nominees for director are elected as contemplated in this management proxy circular, the Board will be composed of 11 non-employee directors and Mr. Williams. 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 form of proxy intend to vote FOR the election of the nominees whose names appear on pages 7 to 12. 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 form of proxy reserve the right to vote for another nominee at their discretion unless the proxy specifies the common shares are to be withheld from voting in the election of directors.

Majority Voting for Directors. The Board has adopted a policy that requires that any nominee for director who receives a greater number of votes "withheld" than votes "for" his or her election as a director shall submit his or her resignation to the Governance Committee of the Board for consideration promptly following the meeting. This policy applies only to uncontested elections, meaning elections where the number of nominees for directors is equal to the number of directors to be elected. The Governance Committee shall consider the resignation and shall provide a recommendation to the Board. The Board will consider the recommendation of the Governance Committee and determine whether to accept it within 90 days of the applicable meeting. A news release will be issued promptly by Suncor announcing the Board's determination, including, if applicable, the reasons for rejecting the resignation. The Board shall accept the resignation absent exceptional circumstances. The resignation will be effective when accepted by the Board. 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.

(4)
  Current status reflects the multiple of the share ownership target met by the director as at December 31, 2015.

No proposed director has been subject to: (a) any penalties or sanctions imposed by a court relating to securities legislation or by a securities regulatory authority or has entered into a settlement agreement with a securities regulatory authority, or (b) any other penalties or sanctions imposed by a court or regulatory body that would likely be considered important to a reasonable securityholder in deciding whether to vote for a proposed director.

Appointment of Auditors

Management and the Board propose that PricewaterhouseCoopers LLP be re-appointed as Suncor's auditors until the close of the next annual meeting. PricewaterhouseCoopers LLP have been Suncor's auditors for more than five years. Unless authority to do so is withheld, the persons named in the form of proxy intend to vote FOR the appointment of PricewaterhouseCoopers LLP.

Fees paid and payable to PricewaterhouseCoopers LLP for the years ended December 31, 2014 and 2015 are detailed below.

Tax Fees |  | 88 |  | 90 |
All Other Fees |  | 15 |  | 15 |
Total |  | 6 409 |  | 7 192 |

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

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

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

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

All services described beside the captions "Audit Fees", "Audit-Related Fees", "Tax Fees" and "All Other Fees" were approved by the Audit Committee in compliance with paragraph (c)(7)(i) of Rule 2-01 of Regulation S-X under the U.S. Securities Exchange Act of 1934, as amended (the "Exchange Act").

Advisory Vote on Approach to Executive Compensation

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

We hope you will carefully review the "Letter to Shareholders" beginning on page 23 and our "Compensation Discussion and Analysis" beginning on page 26 of this management proxy circular before voting on this matter. We encourage any shareholder who has comments on our approach to executive compensation to forward these comments to the chair of the Human Resources & Compensation Committee ("HR&CC") c/o the Corporate Secretary, Suncor Energy Inc., P.O. Box 2844, 150 – 6th Avenue S.W., Calgary, Alberta, T2P 3E3. The "Compensation Discussion and Analysis" section discusses our compensation philosophy and approach to executive compensation, what our Named Executive Officers are paid and how their level of compensation is determined. This disclosure has been approved by the Board on the recommendation of the HR&CC.

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

"RESOLVED, on an advisory basis and not to diminish the role and responsibilities of the Board of Directors, that the shareholders accept the approach to executive compensation disclosed in the management proxy circular of Suncor Energy Inc. delivered in advance of its 2016 annual meeting of shareholders."

As this is an advisory vote, the results will not be binding upon the Board. However, in considering its approach to compensation in the future, the Board will take into account the results of the vote, together with feedback received from shareholders in the course of our engagement activities. Since instituting a vote on an advisory resolution on our approach to executive compensation in 2011, Suncor has received strong support from shareholders with an average of 93.4% of votes "for", including 93.5% of the votes cast in favour in 2015.

Shareholder Proposals

Set forth in Schedules A and B of this management proxy circular are the shareholder proposals that have been submitted for consideration at the meeting and the Board's and management's voting recommendations thereon.

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 15

BOARD OF DIRECTORS COMPENSATION

Philosophy and Approach

Philosophy. Compensation of non-employee directors is intended to:

•
  provide an appropriate level of remuneration to enable Suncor to attract highly qualified individuals with the capability to meet the demanding responsibilities of Board members; and
•
  closely align non-employee directors' interests with shareholder interests.

Approach. The Governance Committee reviews Board compensation levels periodically to ensure Suncor's approach to Board compensation is competitive at the median of the Suncor Compensation Peers (as defined below), and takes into account governance and best practice trends.

The total compensation structure for non-employee directors consists of annual retainers, meeting fees and an annual equity award provided in the form of DSUs.

When reviewing Board compensation levels, the Governance Committee engages Willis Towers Watson to benchmark compensation for non-employee directors and the Board chair and provide information on Board compensation governance and best practice trends. This information is used by the Governance Committee in determining the compensation components, mix and pay level for non-employee directors, including the Board chair, that is recommended to the full Board for approval.

Structure

Suncor's North American energy peers, identified on page 34 of this management proxy circular (the "Suncor Compensation Peers"), used for benchmarking Suncor's non-employee director and Board chair compensation structure are the same companies used for benchmarking senior executive compensation. Suncor's rank, as compared to the Suncor Compensation Peers, in relation to revenue, assets and market capitalization, is also provided on page 34 of this management proxy circular.

The following tables display the compensation structure for 2015 for all non-employee directors, including the Board chair.

  Provides for travel from residence within continental North America to attend Board, committee or orientation meetings.
(3)

  The number of DSUs to be awarded in 2015 was set by the Board at the beginning of 2015 based on a target value for non-employee directors (other than the Board chair) of $217,500 (which equaled 5,960 DSUs) and the Board chair of $280,000 (which equaled 7,680 DSUs). DSUs are awarded in equal quarterly installments.
(5)
  No other compensation was payable to the Board chair for 2015.

Building Equity Ownership. Share ownership guidelines are one way non-employee directors demonstrate their commitment to Suncor's long-term success and alignment with shareholders. For 2015, share ownership guidelines were $1,400,000 for the Board chair and $540,000 for all other non-employee directors. The level of ownership must be attained by each director within five years of when he or she is first elected or appointed. Suncor common shares and DSUs count toward the share ownership guideline.

As at December 31, 2015, all non-employee directors, including the Board chair, have met or are on track to meet the share ownership guidelines. New directors have five years from the date they join the Board to attain the current share ownership level.

"A substantial share ownership requirement of more than $500,000, which has been increased to $800,000 for 2016, for non-employee directors, demonstrates alignment with shareholders' interests."

Share ownership guidelines are reviewed periodically based on survey data.

  Mr. Williams, Suncor's President and CEO, did not receive compensation for serving as a member of the Board. Please refer to page 54 of this management proxy circular for specifics of the compensation provided to Mr. Williams for the year ended December 31, 2015. Ms. Bedient is not represented in the Board compensation tables, as she was appointed to the Board subsequent to December 31, 2015.
(2)
  Share-based awards consist of DSUs, which are determined annually and awarded in equal quarterly installments, and in the case of Ms. Côté, also include DSUs granted upon joining the Board. Effective November 16, 2015, the HR&CC approved changing the grant date market value calculation for DSUs under the DSU Plan. Grant date fair market value was calculated based on the average of the high and low price of a Suncor common share on the TSX for the trading day immediately preceding the date of each quarterly award for the first three quarters of 2015 and was based on the five trading days immediately preceding the date of the quarterly award for the last quarter of the year ($36.50, $34.03, $35.09 and $36.47, respectively). For Ms. Côté, who also received a joining grant in 2015, the value used for this joining award was $39.24. DSUs cannot be redeemed by non-employee directors until they cease to hold office.

Equity Based Compensation

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

"DSUs, which represent over 70% of the annual target pay for non-employee directors, other than the Board chair for whom they represent over 50%, provide a meaningful portion of target pay tied to Suncor's long-term success."

Under the DSU Plan, each non-employee director receives an annual DSU grant as part of his or her total compensation. The annual grant of DSUs is generally awarded in equal quarterly installments.

Each non-employee director, other than Mr. Simpson, who is Board chair, Ms. Côté, who became a member of the Board on February 3, 2015, Messrs. Haseldonckx and Lamarre, who retired from the Board on April 30, 2015, and Ms. Bedient, who was appointed to the Board subsequent to year end, received 5,960 DSUs in 2015. The Board chair received 7,680 DSUs. Ms. Côté received 11,423 DSUs, comprised of a prorated annual grant of 5,463 DSUs and a joining grant of 5,960 DSUs. Messrs. Haseldonckx and Lamarre received 1,490 DSUs each. In 2015, non-employee directors, including the Board chair, received an aggregate of 75,723 DSUs.

For each new non-employee director, the DSU Plan provides for a joining grant of DSUs equal to the annual grant for the year in which he or she is appointed to the Board. New non-employee directors, including any new Board chair, who join the Board during the year will receive a pro-rated annual DSU grant based on the date they join the Board.

Fees Paid in DSUs. Until share ownership guidelines for non-employee directors are met (see page 17 of this management proxy circular for details), non-employee directors receive one-half or, if they choose, all of their fees (excluding expense reimbursements) in the form of DSUs. The number of DSUs to be credited to the non-employee director's account on each payment date is equal to the number of Suncor common shares that could have been purchased based on the market value on the quarterly payment date based on the fees allocated to the director. On each dividend payment date for Suncor common shares, an additional number of DSUs, equivalent to the number of Suncor common shares that could have been acquired on that date by notional dividend reinvestment based on the market value, are credited to the non-employee directors' DSU accounts.

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

Stock Options. In line with governance best practice, stock option grants to non-employee directors were discontinued effective January 1, 2009. For additional information on any remaining stock options awarded prior to 2009 and held by certain non-employee directors, see Schedule C.

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

Looking Ahead to 2016:

The Governance Committee did not recommend any changes to non-employee director and Board chair compensation for 2016.

Following a review of current share ownership guidelines in November 2015, the Governance Committee recommended to the Board that the current share ownership guideline level for non-employee directors be increased from $540,000 to $800,000 beginning in 2016. This level of share ownership represents approximately three times the annual retainer and annual equity award target value for directors and places Suncor well above the median of the Suncor Compensation Peers in terms of this metric.

No change was recommended to the Board chair share ownership guideline, as the share ownership guideline level remains above the median of the Suncor Compensation Peers.

EXECUTIVE COMPENSATION

Letter to Shareholders

To Our Fellow Shareholders:

As the chair of the Human Resources and Compensation Committee ("HR&CC") and chair of the Board of Directors (the "Board") of Suncor Energy Inc. ("Suncor"), we're pleased to share with you how we manage senior executive compensation at Suncor and how the company's programs align with short- and long-term performance.

2015 Business Environment. In 2015, the energy industry faced a volatile, rapidly changing and very challenging business environment, highlighted by a dramatic drop in crude prices. The Board recognizes this has had a significant effect on share prices and ultimately on shareholder value in the industry and that Suncor shareholders were not immune.

However, the Board and the executive leadership team, led by our President and CEO, have responded strongly to this difficult environment. Suncor's integrated strategy, sound balance sheet, capital discipline and continued asset reliability improvements proved to be a solid foundation to weather the deteriorating conditions. We took swift and meaningful action to control operating expenditures and drive efficiencies during 2015 and into 2016. This enabled Suncor to ride out the current downturn and helped ensure the company is well positioned to deliver profitable growth and sustained long-term value for our shareholders.

Responsible Management of Executive Compensation. Suncor's strong pay-for-performance philosophy underpins the design of our programs, which is demonstrated in the proportion of at risk mid- and long-term incentives provided to our senior executives in their total direct compensation. The performance of our company and our senior executives is evaluated annually against goals that are set through a rigorous process focused on continuous improvement. We also review our senior executive compensation governance practices regularly to ensure they align with leading practices and shareholder interests.

The HR&CC reviewed our senior executive compensation programs during the fourth quarter of 2015 and did not identify the need for any changes in the total direct compensation structure. We believe this structure is aligned with leading practices. Importantly, the decision was also made that 2016 annual base salaries will continue to be held at 2014 levels.

More information on Suncor's compensation programs and governance practices can be found beginning on page 26 of our management proxy circular.

Suncor's Market for Senior Executives. Suncor is a substantial company with global operations and multiple business units. We were the largest energy company by market capitalization in Canada, and the sixth largest in North America at the end of 2015.

Given the size and scope of Suncor, we compete with comparable energy companies across North America for top executive talent. To ensure that executive pay programs are competitive, we look to a group of Canadian and U.S. energy companies when we benchmark pay levels for our senior executive team.

Consistent with our approach to benchmarking pay, we measure our total shareholder return performance under our Performance Share Unit ("PSU") plan against a very similar group of peers. This approach aligns with our pay philosophy, ensuring that we provide competitive pay and that Suncor's performance relative to our peers directly impacts the ultimate pay realized by our senior executives.

Supporting Performance. Suncor's senior executive compensation program is designed to support and reinforce Suncor's value drivers and the attraction and retention of skilled and talented leaders. The value drivers include achieving and maintaining safe and reliable operations, environmentally and socially responsible practices and industry leading returns. Our success in these areas will drive long-term value for our shareholders.

For 2012 through 2015, Suncor has demonstrated strong performance in a number of key operational areas and in total shareholder return ("TSR") compared to peers and the S&P/TSX Capped Energy Index.

The charts that follow display Suncor's performance over time in two important areas: Suncor's Recordable Injury Frequency ("RIF"), a key safety measure, as compared to Canadian Association of Petroleum Producers ("CAPP") industry data; and Suncor's TSR compared to the median of our peer group used for benchmarking senior executive compensation and to the median of the S&P/TSX Capped Energy Index. We focus on TSR for the period 2012 through 2015 to reflect performance during Steve Williams' tenure as President and CEO.

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 23

Safety is an important value driver for Suncor in support of sustainable development and achieving long-term operational and financial success. Our ongoing focus on safety has resulted in continuing improvement in RIF over the period.

Suncor's TSR during the 2012 through 2015 period outperformed peers three of the four years, including by a significant margin in 2015. We outperformed the median of the S&P/TSX Capped Energy Index in all four years. Suncor also increased its dividend by 12% in 2015. This followed increases of 40% in 2014 and of 54% in 2013.

While the industry faced significant volatility and a challenging business environment in 2015, Suncor distinguished itself with overall strong operating and financial performance compared to its peers. Information on the performance, accomplishments and compensation of our Named Executive Officers ("NEOs") can be found beginning on page 38 of our management proxy circular.

2015 President and CEO Pay Outcomes. Almost 90% of the President and CEO's 2015 total direct compensation varied with performance and approximately 68% was provided in the form of mid- to long-term incentives, tying a substantial portion of the President and CEO's compensation to increasing shareholder value. In 2015, Mr. Williams' total direct compensation (which includes his actual salary + actual bonus + the grant date fair value of his annual mid- to- long-term incentive awards) was $12.8 million, up 4% from $12.3 million for 2014.

Realizable Long-Term Pay Aligns With Shareholders' Interests. The equity based and performance contingent structure of our mid- to long-term compensation programs ensures that the value ultimately received by our NEOs is aligned with our shareholders. Over the 2013 to 2015 period, aggregate realizable total direct compensation of our NEOs was approximately 14% lower than the value reported in the summary compensation table.

While the NEOs have realized better than target short-term incentive compensation from strong operational performance over the period, the aggregate realizable value of the annual mid- to long-term incentive compensation was 19% below the value reported in the summary compensation table for the 2013 to 2015 period.

The realizable value reflects both the "in-the-money" value of stock options based on the absolute share price increase from the date of the long-term compensation award and TSR performance relative to peers under the PSU plan. The realizable value of the mid- and long-term incentive compensation was generally in line with Suncor's share price and relative TSR performance over the period and reinforces Suncor's pay-for-performance philosophy and alignment with shareholder interests.

24 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

Looking Ahead to 2016. The dramatic collapse in oil prices during 2015 and into early 2016 has proven to be a significant challenge for energy industry companies. We strongly believe that Suncor is well positioned to respond to this challenge in 2016 and over the longer term and we will continue to take steps to preserve the interests of and grow value for our shareholders.

Your Board, with the support of the HR&CC, is committed to ensuring that Suncor's senior executive compensation continues to be aligned with our shareholders' interests and supports Suncor's near-term and longer-term competitiveness and future success.

We welcome shareholder feedback on Suncor's business operations, policies and practices, including executive compensation.

Sincerely,

John D. Gass Chair of the Human Resources & Compensation Committee |  | James W. Simpson Chair of the Board

Pay and Performance Overview

Suncor's executive compensation programs are designed to align the interests of our executives with shareholders, rewarding executives for delivering annual and longer term results and building sustainable shareholder value.

Our business is linked to the commodity cycle with significant and long-term capital needs, and requires focus on profitable growth that is achieved through capital discipline and reliable operations conducted in a safe and environmentally and socially responsible way.

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

26 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

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

Financial Results |  | Value Drivers(2) |  | Leadership |  | Shareholder Value |
CFOPS(1) ROCE(1) |  | Operational excellence Sustainability Maintenance & reliability Industry leading returns Culture & workforce performance |  | Personal performance, which includes the successful execution of operational and capital plans. |  | Relative total shareholder return ("TSR") through our performance share unit ("PSU") plan ("PSU Plan"). Absolute share price appreciation through stock options. |

(1)
  CFOPS and ROCE are non-GAAP measures. See the "Advisories" section beginning on page 68 of this management proxy circular.
(2)
  For 2016, the value drivers will be Safety, Sustainability, Base Business, Growth and Workforce and Organizational Performance.

How Total Direct Compensation is Delivered.

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

Component |  | Performance Orientation |  | Time Frame |
Salary (15-35% of target compensation) |  | Reflects the market value of the position. Salary increases reflect performance demonstrated on the job. |  | Annual review with adjustments as appropriate |
Annual Incentive (15-17% of target compensation) |  | Aligns with financial and operational performance objectives. Reflects a combination of corporate, business unit and personal performance. |  | Short-term Annual performance |
PSUs (25-35% of target compensation) |  | Rewards relative share price performance. Fully at-risk with a 0% to 200% of target payout range (three of the ten grants since program inception resulted in no payout as performance conditions were not met). |  | Mid-term Three-year rolling performance cycles |
Stock Options (25-35% of target compensation) |  | Rewards absolute share price performance. Only delivers value if our share price appreciates (as at December 31, 2015, only two of the past five annual option grants are "in-the-money"). |  | Long-term Seven-year term Vest over three years |

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 27

Pay Alignment to Total Shareholder Return. Suncor has a long-standing pay-for-performance philosophy that is reflected in the design of our programs. A significant portion of the NEOs' total direct compensation is performance contingent and is linked to Suncor's financial results, operating results and share price performance. The alignment of our pay programs with performance over short- and mid- to long-term periods is regularly reviewed, to ensure that our short-term actions lead to long-term increases in shareholder value.

In reviewing alignment of our pay programs relative to performance we look at two different pay perspectives: pay opportunity and realizable pay.

Pay Opportunity |  | Realizable Pay |
Static numbers reported in the Summary Compensation Table for total direct compensation in 2013 and 2014 and estimated pay for 2015. It does not reflect the impact of share price on the ultimate value received through equity awards. |  | Dynamic numbers that capture total direct compensation reflecting the current value of outstanding equity awards. The values ultimately received could be quite different than those in the Summary Compensation Table depending on future performance. |

The charts below indicate the alignment between Suncor's President and CEO's pay and TSR over the past three-years for pay opportunity and realizable pay relative to the chief executive officers of the Suncor Compensation Peers as identified on page 34.

Suncor's President and CEO's pay opportunity is positioned slightly outside the zone of reasonable alignment indicating the company's strong relative TSR performance which exceeds its relative pay. Only one peer had better TSR performance, while six peers had a higher pay opportunity.

When assessing pay outcomes versus performance, realizable pay for Suncor's President and CEO falls within the zone of alignment compared to peers.

(1)
  Data used for the Pay Opportunity chart for peer companies is based on information extracted from 2013-2015 public disclosure filings. For peer companies, 2013 and 2014 amounts are actuals. The 2015 pay opportunity amounts reflect actual 2015 salaries where disclosed as compiled by Willis Towers Watson (otherwise salaries assumed to equal 2014 amounts, recognizing the prevalence of salary freezes in 2015); 2015 bonuses are estimated based on 2015 salaries multiplied by the actual 2014 bonus payment as a percentage of 2014 salary; and 2015 equity awards are actual amounts from public disclosure for 14 of the 17 peer companies, and for the remaining three peer companies, where actual 2015 equity award data was not available, an estimate was used based on past equity awards.

(2)
  Data used for the Realizable Pay chart for peer companies is the same as for Pay Opportunity for base salaries and bonuses; the equity award amounts are based on the equity award data used in the Pay Opportunity analysis with the values for the options equal to the "in-the-money" value based on the December 31, 2015 share price for each peer company. PSU amounts assume target payouts and a December 31, 2015 share price for each peer company.

(3)
  TSR ranking based on three-year TSR.

President and CEO Pay Multiple of Median Peer Group Pay. We also look at the pay opportunity for the President and CEO as a multiple of the median pay opportunity of the Suncor Compensation Peers. The 2015 pay for the President and CEO compared to the pay opportunity for our peer group based on current data is at a multiple of 1.4 times the median of the Suncor Compensation Peers, with the majority of the difference in mid-to-long-term performance contingent pay. The HR&CC believes there is no excessive pay disparity between Suncor's President and CEO and market pay, given Suncor's size and performance versus peers. The pay multiple is well within the acceptable range based on institutional investor and governance practices.

28 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

President and CEO Pay at a Glance. As displayed in the corresponding chart, Mr. Williams' actual 2015 total direct compensation is approximately 27% higher than Suncor's benchmarked target total direct compensation structure(1) at the median of the Suncor Compensation Peers. The 2015 actual compensation level reflects Mr. Williams' personal performance for the past year as assessed by the Board and the corporate and business unit results for 2015. For more information on Mr. Williams' performance and compensation in 2015, see pages 43 to 44 in this management proxy circular.

(1)
  For 2015, the base salary component of the target total direct compensation structure for the President and CEO was reduced from $1,540,000 to $1,300,000 in line with benchmark data. This change impacted the target value for stock options and PSUs, as the target value is based on a multiple of target base salary.

Pay Programs Are Supported By Key Governance Practices. Suncor has implemented and maintains a number of key executive compensation governance practices which we believe are consistent with best practice approaches, support our business objectives and align with shareholder interests.

Compensation 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, including the HR&CC. Further details relating to Board committees can be found in Schedule E to this management proxy circular.

Human Resources & Compensation Committee. Central to the role of the HR&CC is the alignment of executive compensation with the delivery of shareholder value. The capabilities, powers and operation of the HR&CC under its mandate include assisting the Board annually in the areas of executive compensation, succession planning, incentive compensation plans and compensation governance. Key objectives in these areas include:

•
  reviewing and approving the overall corporate goals and objectives of Suncor relevant to compensation of the President and CEO, and ensuring that the overall goals and objectives of Suncor are supported by an appropriate executive compensation philosophy and programs;
•
  evaluating the performance of the President and CEO against approved goals and criteria, and recommending to the Board the total compensation for the President and CEO in light of the evaluation of the President and CEO's performance;
•
  reviewing the President and CEO's evaluation of the other senior executives' performance and recommendations for total compensation of these senior executives;
•
  reviewing the succession planning process and results for senior executive roles;
•
  reviewing NEO and other senior executive termination agreements and NEO termination obligations in relation to market practices and trends;
•
  reviewing compensation programs using a risk assessment framework to help ensure Suncor's compensation programs and practices do not encourage the taking of excessive or inappropriate risks;
•
  reviewing, on a summary basis, any significant compensation, pension and benefit programs for employees generally, with consideration of accounting, tax, design, legal, regulatory and risk implications and the pay-for-performance relationship for variable pay; and
•
  reviewing executive compensation disclosure and recommending it to the Board for approval before Suncor publicly discloses this information.

The HR&CC fulfilled its mandate, as summarized in this section, in 2015.

All HR&CC members are independent directors. The HR&CC is currently comprised of the following members: John D. Gass (chair), Mel E. Benson, W. Douglas Ford, John R. Huff and Eira M. Thomas.

The HR&CC members have experience in top leadership roles (two of five in CEO roles), strong knowledge of the energy industry (four of five with an energy industry background), a mix of functional experience and competency, and tenure as directors of various public companies. This background provides the HR&CC with the collective experience, skills and qualities to effectively support the Board in carrying out its mandate. Further information on the HR&CC committee member experience and skills is provided in the inventory of Board member capabilities and competencies on page E-13 of Schedule E to this management proxy circular.

Executive Compensation Consultants. Willis Towers Watson provides advice to the HR&CC, supports management in the area of executive compensation and provides services in other human resources areas, including pensions. Willis Towers Watson has protocols in place to ensure that they are in a position to provide independent advice. Willis Towers Watson was originally retained in February 2006.

Meridian Compensation Partners ("Meridian") is retained by the HR&CC as its independent advisor. Meridian was originally retained by the HR&CC in February 2010.

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

•
  expertise and advice in the development of compensation policies and programs for executives and the Board;
•
  periodic updates on best practices, trends and emerging regulatory or governance matters related to executive compensation;
•
  custom survey work benchmarking Suncor compensation in the marketplace; and
•
  support in conducting an annual risk assessment of Suncor's compensation policies and programs.

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

•
  provides executive compensation advice and perspective to the HR&CC;
•
  validates or challenges proposals, recommendations and the decision process followed; and

30 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

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

The decisions made by the HR&CC may reflect factors and considerations other than as provided or recommended by our compensation consultants. During 2015, Willis Towers Watson and Meridian met with the HR&CC chair and attended relevant sections of HR&CC meetings, as necessary.

Executive Compensation-Related Fees

Executive compensation-related fees paid by Suncor in 2015 and 2014 to Willis Towers Watson and Meridian are displayed in the table below.

Executive Compensation Consultant |  | Fees Paid related to 2015 ($) |  | Fees Paid related to 2014 ($) |
Willis Towers Watson |  | 87 285 |  | 151 829 |
Meridian |  | 22 024 |  | 23 613 |

All Other Fees

In addition to the fees disclosed above, Willis Towers Watson assisted in certain matters related to pension and benefits, including, but not limited to, actuarial and accounting services. Total fees payable to Willis Towers Watson for the foregoing services were $1,045,754 in 2015 and $1,501,635 in 2014, which included all fees payable to Willis Towers Watson by Suncor not included under executive compensation related fees in 2015 and 2014, respectively. Other than the fees disclosed above, no other fees were paid by Suncor to Meridian in 2015 and 2014.

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

Managing Compensation Risk. Suncor's executive compensation policies and programs are designed to create appropriate incentives to increase long-term shareholder value. While the energy business by its nature requires some level of risk-taking to achieve returns in line with shareholder expectations, Suncor structures compensation plans and programs and maintains guidelines and policies which it believes limits excessive risk. Key oversight procedures and risk mitigating features to support managing compensation risk are outlined below.

"An effective combination of oversight procedures and compensation program risk mitigating features, including plan designs, policies, guidelines and governance practices, limit the potential for programs to encourage unacceptable and excessive risk taking."

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 31

Oversight Procedures

• Suncor's strategic plan, as reviewed by the Board, balances investment risk and reward, and assesses company and industry risks in advance to support planning, risk management and decision making. • Suncor uses tools including an Enterprise Risk Management System, Operational Excellence Management System and Trading Risk Management Policy to identify and manage risk. • In the normal course of business, Suncor has financial controls that provide limits and authorities in areas such as capital and operating expenditures, divestiture decisions and marketing and trading transactions. These financial controls mitigate inappropriate risk-taking. |  | • The HR&CC uses a compensation program risk assessment framework in assessing Suncor's compensation policies and programs to determine whether any components could encourage unacceptable excessive risk taking. • The elements of the compensation risk assessment framework are categorized in four areas: pay philosophy and compensation structure, plan designs, performance metrics and governance. • The HR&CC reviews the results of the compensation program risk assessment annually to take account of any significant shifts in Suncor's business strategies or compensation policies and programs. Their review in 2015 confirmed that Suncor's compensation policies and programs do not encourage excessive risk that could have a material adverse effect on Suncor. |

Key Risk Mitigating Features

Plan and Program Design |
• Total direct compensation for executives provides a balance between base salary and variable performance contingent compensation. For our NEOs, emphasis is not focused on one compensation component, but is spread across annual, mid- and long-term programs to support and balance sustained short-term performance and long-term profitability. • For our NEOs, typically 80% or more of their target total direct compensation is variable based on company, business unit and personal performance and the remaining 20% or less is base salary. Of the 80% or more of variable compensation, approximately 80% or more is mid- and long-term focused and approximately 20% or less is short-term focused. The strong weighting towards mid- to long-term compensation mitigates the risk of undue emphasis on short-term goals at the expense of long-term sustainable performance. • Annual grants of stock options vest over three years and have a seven-year term, reinforcing the goal of building and sustaining long-term value in line with shareholder interests. • Our mid-term PSU Plan rewards relative TSR performance over three years versus our PSU peer group of companies, as described on page 62 of this management proxy circular. Annual awards and overlapping three-year performance periods deter short-term focused decision making and require sustained high levels of performance to achieve a consistent payout. • For PSU grants, there is no payout if relative TSR performance is in the bottom grouping of companies, a payout cap of 200% of target when relative TSR performance is in the top company grouping of the peer group and a sliding scale of payout levels based on each company grouping in between. |  | • The AIP for all salaried employees is inherently designed to limit risk. Short-term incentive pay is earned based on achievement against a balanced and diversified mix of performance measures. The measures include both financial and operating performance targets. This balanced approach discourages focus on a single measure at the expense of other key factors (e.g., profitable growth at the expense of safety). This design diversifies the risk under any one performance area. • AIP targets, results and payouts are stress tested and reviewed by the HR&CC. • The funds to provide for annual cash payouts under the AIP are determined based on key corporate measures and a scorecard for each business unit with consistent measurement across areas critical to Suncor's success. • A threshold for payouts under the AIP is established each year. For 2015, the threshold was based on achievement of a cost reduction target. • Under the DSU Plan, executives may elect annually to allocate 25% to 100% of their AIP payment to DSUs. This feature in the DSU Plan is used by executives to assist in meeting share ownership requirements and defers annual incentive compensation, further encouraging a focus on long-term performance. For the 2015 performance period, four of the NEOs elected to take a portion of their AIP payment in DSUs. |

Policies and Guidelines |
• Suncor's total compensation for executives is regularly benchmarked against a peer group of companies of similar size and business scope approved by the HR&CC. This ensures that compensation is competitive with peers and aligned with Suncor's philosophy. • Suncor executives must achieve and maintain specific share ownership levels based on a multiple of their annual salary. A substantial share ownership level assists in aligning executive interests with those of shareholders. The share ownership guidelines for NEOs are found on page 35 of this management proxy circular. |  | • The President and CEO must maintain his share ownership requirement level through the first year following retirement. • The HR&CC and the Board provide strong oversight of the management of Suncor's compensation programs. The HR&CC has discretion in assessing performance under executive compensation programs to adjust metrics or the payouts based on results and events, and have used the discretion to reduce or increase payouts under certain programs in the past. |

Conclusion

Given the oversight procedures and the key risk mitigation features of Suncor's compensation policies and programs described above, the HR&CC does not believe that there are any identified risks arising from the company's compensation policies and practices that are reasonably likely to have a material adverse impact on the company.

Our Approach to Executive Compensation

Pay Philosophy. Suncor maintains a strong pay-for-performance philosophy that is demonstrated in the mix of compensation provided to executives and the way we measure success. Compensation plans and practices are tied to our strategy, performance, talent and risk management business objectives.

A significant portion of the total direct compensation of our senior executives is provided in variable performance contingent pay designed to reward superior business performance and increasing shareholder returns. This approach ensures alignment with shareholder interests and reinforces our pay-for-performance philosophy. For our senior executives, incentive-based pay is designed to reward successful short-, medium- and long-term performance in key areas, including operational excellence, sustainability, maintenance and reliability, industry leading returns, culture and workplace performance, CFOPS, ROCE, TSR performance relative to peers, absolute share price performance and leveraging our integrated strategy, all of which enable results that are important to our shareholders.

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

Defining Our Marketplace. Our senior executives are responsible for managing a large, global enterprise with multiple operating units and significant capital expenditures. Our capital expenditures of over $6.2 billion in 2015 were larger than the market capitalization of a majority of Canadian companies.

As the largest energy company in Canada and sixth largest in North America by market capitalization at December 31, 2015, size and business scope are key criteria in defining the marketplace and peer companies used to establish competitive compensation levels for our senior executives. This means we must look beyond Canadian energy companies and include U.S. energy companies in our peer group in order to capture a sufficient number of companies of comparable size and complexity.

The peer group used to benchmark compensation levels for Suncor's senior executives in 2015, including the NEOs identified on page 26 of this management proxy circular, is approved by the HR&CC. The peer group and selection criteria are regularly reviewed by the committee and include energy sector specific companies, financial and operational comparability, nature and scope of operations and represent our market for executive talent.

Our peer group for 2015 is comprised of the 17 North American based energy companies listed below and provides a robust sample to ensure that changes made by a single company do not unduly influence benchmark data. In Canada, we include pipeline companies, since there are fewer comparable large upstream and integrated energy companies and because pipeline companies form part of our labour market. In the U.S., where there are more large upstream and integrated companies, we limit the peer companies to comparable upstream and integrated energy companies.

  Talisman Energy Inc. will be removed from the Suncor Compensation Peers for 2016 as it was acquired by Repsol S.A.

A similar peer group of companies is used in determining the relative TSR performance for our PSU grants as described on page 62 of this management proxy circular. Differences in the two peer groups reflect the specific purpose of each group (i.e., benchmarking of executive pay versus comparing company shareholder return performance).

Suncor ranks as one of the largest companies, as compared to the Suncor Compensation Peers, in relation to revenues, market capitalization and assets.

The chart below shows Suncor's ranking as compared to the Suncor Compensation Peers.

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

The share ownership guidelines are reviewed periodically to ensure they are market competitive and are consistent with good governance practice. These guidelines visibly align senior management's interests with those of Suncor's shareholders and are supported by market benchmark data.

2015 and 2016 Guidelines. The share ownership guideline level must be achieved by the end of the fifth year after appointment to an executive position or promotion to a more senior executive position. On promotion to a more senior executive position, the prior guideline level must be maintained at the new base salary level. Only Suncor common shares and DSUs count toward fulfillment of the guidelines; PSUs, restricted share units ("RSUs") and stock options do not. Where share ownership guidelines have not been met within the prescribed period, executives must use the cash payout from their annual incentive award, a current vested PSU grant payout, or other cash resources to immediately satisfy any shortfall to the current share ownership guideline for their level.

Following review of President and CEO benchmark data for the Suncor Compensation Peers in 2015, the HR&CC has increased the share ownership guideline for the President and CEO beginning in 2016 to six times base salary. The guidelines for other executive levels remain competitive with the Suncor Compensation Peers and no changes have been made for 2016.

The following table sets forth the compliance of each NEO with the share ownership guidelines as at December 31, 2015. All NEOs have either already met or are on track to meet their share ownership guideline level and compliance date.

  The holdings shown in the foregoing table for Suncor common shares and DSUs are rounded for display purposes. The holding value of these units is calculated based on the total holdings including the fractional units, as at December 31, 2015.

President and CEO Hold Requirement. The President and CEO must maintain his share ownership level for one year following his retirement, which aligns with current good governance practices and shareholder interests.

Total Direct Compensation Components. Total direct compensation, made up of base salary, an annual incentive and mid- to long-term incentives, is designed to reward short-term results and achievement of sustained longer-term performance in key business areas that enable the operational and financial results important to our shareholders.

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

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 35

  For the leader of a business unit, the 60% Business Unit component is based one-third on the leader's business unit performance and two-thirds on the weighted average performance of all four business units of Suncor. This reinforces alignment to Suncor's integrated strategy and reflects the important role collaboration plays in delivering sustained company performance. For the President and CEO and executives in corporate functions, the 60% is based on the weighted average performance of all four business units of Suncor. 2015 business units for the purpose of AIP are as follows: Oil Sands & In Situ; Exploration & Production ("E&P"); Downstream; and Major Projects.

Key LTI Plan Terms. Suncor's business involves strategic investments over long periods of time. With stock options and PSUs as key elements of long-term incentive ("LTI") compensation, NEOs are fully aligned with the economic interests of our shareholders over a medium- and long-term horizon, are significantly leveraged from an ultimate compensation standpoint to Suncor's share price and are rewarded based on a balance between relative (PSUs) and absolute (stock options) pay-for-performance measures. The following table provides the key LTI plan terms for equity awards provided to the NEOs and other executives as part of their competitive compensation.

|  | Performance Share Units (PSUs) |  | Stock Options
Term |  | Three years |  | Seven years
Description |  | Share units mirror common shares with performance conditions that affect the vesting level (between 0% and 200% of grant) |  | Options to acquire common shares
Frequency |  | Granted annually |  | Granted annually
Performance Conditions |  | TSR performance relative to peers |  | Only have value when the common share price exceeds the exercise price
Vesting |  | After a three year performance period Vesting level is subject to performance condition achievement and HR&CC approval |  | 1/3 vest each year starting on January 1 of the year following the annual grant and are based on the share price at the time of grant
Payout |  | Paid out in cash following the end of the three year performance period based on units held, vesting and market value of a common share |  | On exercise, acquire common shares at the price determined at the time of grant
Employment Termination(1) |  | Resignation – units are cancelled Involuntary Termination – units are cancelled Retirement – units are held to end of the performance period and paid out based on vesting level |  | Resignation – unvested options are cancelled; vested options may be exercised for up to the earlier of three months or expiry Involuntary Termination – unvested options are cancelled; vested options may be exercised for up to the earlier of three months or expiry Retirement – unvested options vest immediately and all options held may be exercised up to the earlier of three years or expiry

  For NEOs, certain terms and conditions may vary based on their employment termination agreement.

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

Annual Incentive Plan (AIP). Suncor's AIP rewards our NEOs and other AIP participants based on the performance achieved versus the measures and targets approved for each of the Corporate and Business Unit components and the annual goals approved for the personal component.

The charts to the right display the weight for each AIP performance component and for the Business Unit component of AIP, the guideline weight for each of the value drivers. Awards under the AIP are determined based on the combination of the weighted performance for the components.

The 2015 Corporate component of the AIP is comprised of two key corporate-wide financial measures, CFOPS and ROCE, which are important to Suncor's financial strength and profitability. For the Business Unit component, each of Suncor's business units under the AIP has between six and ten standard performance measures (for example, Recordable Injury Frequency) across the five value driver areas for a total of more than 30 measures across the four business units, along with business unit specific measures in each unit. The overall score for the Business Unit component of the AIP is determined based on the performance for each of the four business units and the weighting assigned to each business unit.

The performance targets for the measures in each business unit are based on the budget (for example, production targets) or on improvement (for example, 10% improvement over the prior three year average). The maximum 200% target for the performance range generally represents a 10% improvement on the best performance over the past three years and the 0% target of the performance range generally represents equal to or better than the worst performance result over the past three years (i.e. no payout for poor performance).

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

Information on the individual goals and performance of the NEOs under the Personal component of the AIP can be found beginning on page 43 of this management proxy circular and information on the calculation of their 2015 AIP award can be found on page 42.

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 39

Annual Incentive Plan Performance. In 2015, performance on corporate measures was slightly above target despite falling commodity prices, while business unit results reflected strong operating performance, significant improvement in the key Maintenance & Reliability and Industry Leading Return performance areas and significant overall cost reductions compared to 2014 actuals.

The following table summarizes the overall 2015 performance results for the Corporate and Business Unit components of the Suncor AIP and the scores achieved for each Performance Area versus the 2015 opportunity, including performance highlights.

AIP Component Weight(1) |  | Overall Score(3) |  | Performance Area(5) |  | Key Measures(7) |  | Performance Highlights |  | Aggregate Component Score(3)(8)(9) |
Corporate |  |  |  | CFOPS(6) (10%) |  | CFOPS(8) |  | Achieved cash flow of $6.8 billion vs. an AIP target of $6.7 billion reflecting lower commodity prices offset by strong operating performance, the strength of our integrated business model and cost reduction initiatives |  | 104 |
Measures (20%) |  | 103(4) |  | ROCE(6) (10%) (excluding major projects in progress) |  | ROCE (excluding major projects in progress) |  | Achieved an adjusted ROCE of just over 4.2% vs. a target of 4.2%, again reflecting lower commodity prices, strong operating performance and the other factors benefiting CFOPS |  | 101 |
|  |  |  | Operational Excellence |  | Recordable Injury Frequency ("RIF"), High Potential and High Risk Incidents and Other Business Unit Specific Measures |  | Overall score for Operational Excellence was better than target for all business units; RIF performance was much better than target in E&P and Major Projects |  | 143 |
|  |  |  | Sustainability |  | Number of Environmental Regulatory Non-Compliances, Energy Intensity and Other Business Unit Specific Measures |  | Continued strong overall performance in Sustainability with Oil Sands & In Situ, E&P and Major Projects scores well above target; Oil Sands & In Situ led performance on Environmental Regulatory Non-Compliance and Energy Intensity measures achieving maximum scores |  | 150 |
Business Unit(2) (60%) |  | 150 |  | Maintenance & Reliability |  | Production, Asset Availability and Other Business Unit Specific Measures |  | Very strong asset reliability in Oil Sands & In Situ and Downstream versus targets; production favourable to target; E&P business unit score below target |  | 142 |
|  |  |  | Industry Leading Returns |  | Cash Operating Costs, Execution of Growth Plans and Other Business Unit Specific Measures |  | Overall operating costs favourable to targets across the business units driven by cost reduction initiatives; Major Projects schedule and milestones favourable to target |  | 154 |
|  |  |  | Culture & Workforce Performance |  | Voluntary Attrition and Other Business Unit Specific Measures |  | Downstream, E&P and Oil Sands & In Situ unit scores well above target reflecting very strong performance on measures such as voluntary attrition, leadership capability and employee engagement |  | 167 |

  The scoring opportunity for the Corporate and Business Unit components of AIP range from 0 to a maximum of 200, with a score at target of 100.

40 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

(4)
  For 2015, CFOPS of $8.1 billion and ROCE of 7% (maximum targets) would have had to have been achieved for a maximum score of 200% for the Corporate measures component; CFOPS of $5.2 billion and ROCE of 0.4% (minimum targets) would have resulted in no payout in relation to the Corporate measures; and CFOPS and ROCE results between the minimum and maximum target levels would provide payouts on a sliding scale of between 0% and 200%. The minimum and maximum target levels for the 0% and 200% range reflect a Brent crude oil price at $10 above and $10 below the 100% target or budget level.
(5)
  In 2015, the target weightings for the performance areas in each of the business units were as follows: the Oil Sands & In Situ business unit assigned a 20% target weighting to Operational Excellence, 15% to Sustainability, 30% to Maintenance & Reliability, 20% to Industry Leading Returns and 15% to Culture & Workforce Performance; the E&P business unit assigned a 22% target weighting to Operational Excellence, 10% to Sustainability, 30% to Maintenance & Reliability, 23% to Industry Leading Returns and 15% to Culture & Workforce Performance; the Downstream business unit assigned a 15% target weighting to Operational Excellence, 15% to Sustainability, 20% to Maintenance & Reliability, 35% to Industry Leading Returns and 15% to Culture & Workforce Performance; and the Major Projects business unit assigned a 20% target weighting to Operational Excellence, 5% to Sustainability, 20% to Maintenance & Reliability, 40% to Industry Leading Returns and 15% to Culture & Workforce Performance.

  The resulting actual 2015 overall company target weightings for the five Performance Areas within the Business Unit component of AIP in the foregoing table were as follows: 19% for Operational Excellence, 13% for Sustainability, 26% for Maintenance & Reliability, 27% for Industry Leading Returns and 15% Culture & Workforce Performance.

(6)
  CFOPS and ROCE are non-GAAP measures. See the "Advisories" section beginning on page 68 of this management proxy circular. The AIP ROCE, referred to as Adjusted ROCE, result of just over 4.2% reflects adjustments made for decisions related to asset impairments (including Libya, Joslyn, White Rose and Golden Eagle).
(7)
  Certain measures may not be applicable to all business units. For example, Production is not a measure for the Major Projects business unit. In addition, certain business units may have additional unit specific measures. For example, the Downstream business unit measures include cash operating cost measures focused on Retail, Wholesale, Distribution, Renewables, Supply & Trading and Lubricants operations under Industry Leading Returns. Measures provided are for illustrative purposes.
(8)
  For 2015, the threshold measure for determining if any payments will be made under the AIP was based on a cost reduction target. This change from CFOPS for 2015 aligned with Suncor's objective to accelerate cost reduction efforts in 2015. For a full payout under the 2015 AIP program to occur, a cost reduction target of $550 million had to be achieved. The 2015 cost reduction program was successful and this target was exceeded.
(9)
  The Performance Area scores for the Business Unit component of AIP reflect the aggregate scores achieved across all of the business units. Performance for individual business units will vary from the aggregate scores.

2015 Performance Highlights

Mr. Williams ensured the company's strategic focus on operational excellence, capital discipline and profitable growth remained well articulated and unchanged.

The company incurred a net loss of $1.995 billion, including non-recurring items, in a difficult business environment and achieved operating earnings(1) of $1.465 billion. Progress on cost management and profitability were evident in 2015: a strong management response to the continued decline in oil prices led to a 10% reduction in operating, selling and general ("OS&G") costs and a 5% reduction in capital costs. The company's strategy, guided by Mr. Williams, ensured that in 2015, all dividends and sustaining capital were funded through internal resources, even in the low commodity price environment. With Mr. Williams' guidance, Suncor led the Suncor Compensation Peers in 2015 on TSR.

From an operations perspective, overall total average production was 577.8 mboe/d compared to 534.9 mboe/d in 2014. Oil Sands operations production increased to 433.6 mbbls/d from 390.9 mbbls/d in 2014, reflecting strong performance across the company's operations. Upgrader production for 2015 was at 320.1 mbbls/d, an 11% improvement over the 289.1 mbbls/d achieved in 2014.

Mr. Williams oversaw efforts to reduce operational risk and improve personal and process safety performance. Suncor's Oil Sands Safety Task Force has progressed to plan and is demonstrating significant, sustainable improvement. Key operational controls were deployed across Suncor to improve safety, environmental performance and operator driven reliability. RIF in 2015 was 0.45, a 15% improvement over the prior three year average. A Serious Incident Frequency metric was introduced in 2015 to focus on high consequence personal safety risk. Lost Time Injury Frequency was unchanged at 0.04 compared to the prior year and reflects a 20% improvement over the prior three year average.

With Mr. Williams' guidance, the company continued to make excellent progress in reducing costs. Oil Sands cash operating costs per barrel(1) have been reduced by $5.95 as compared to 2014, coming in at $27.85, which was down 18% year over year.

The President and CEO continued to advance profitable growth objectives, including development of the Fort Hills project. All major milestones in 2015 were achieved through the execution and operating teams and the project remains on track for delivery of sanctioned costs and schedule. The project also achieved top decile construction industry safety performance with a RIF below 0.45.

President and CEO Performance in 2015 (continued)

2015 Performance Highlights

Mr. Williams continued to drive a market access strategy to ensure Suncor will be able to transport its growing production to market with current infrastructure options through the end of this decade. The 2015 Line 9 reversal will increase flexibility by providing Suncor's Montreal refinery with increased access to inland crudes.

Mr. Williams also continued to drive improved performance in support of long-term sustainability goals by focusing on operational excellence and improved reliability, driving progress in new technology investments and participating in industry collaboration to improve environmental performance, including as part of COSIA.

He continued to build and enhance Suncor's reputation by proactively engaging with a broad range of stakeholders. He personally met with, and represented Suncor's interests to, provincial, federal and Aboriginal leaders. On request of the Alberta premier, he agreed to serve as the Co-Chair of the Premier's Advisory Committee on Economic Diversification and was one of a few industry leaders asked to support the federal delegation at COP21 in Paris. In addition, through a committed vision of climate leadership, he worked with industry colleagues and engaged directly with North American environmental leaders, resulting in aligned recommendations to government in connection with an historic, and globally supported, climate framework for Alberta.

Mr. Williams also demonstrated national leadership through his role as an advisor to Canada's Ecofiscal Commission, continued to strengthen Suncor relationships with Aboriginal communities, and offered his support to the community, serving as Co-Chair of Indspire's successful "Building Brighter Futures Campaign".

Through a range of speeches to a variety of audiences and engagement with media, Mr. Williams secured a leading share of voice in the media among Canadian energy producers.

Alister Cowan, Executive Vice President and Chief Financial Officer

Mr. Cowan was appointed Executive Vice President and Chief Financial Officer in July 2014. He is responsible for directing Suncor's financial operations, including controllers, investor relations, treasury, tax, internal audit and enterprise risk management. His efforts are focused on ensuring that Suncor has the financial strength necessary to execute the company's strategic plans.

2015 Performance

2015 Goals

•
  Establish and execute financial strategies in support of achieving the company's business and risk management objectives.
•
  Drive continuous improvement across Suncor, with a focus on capital discipline, cost management and profitable growth.
•
  Enhance the leadership, performance capabilities and effectiveness of the Finance team.
•
  Enhance Suncor's profile and relationships with external stakeholders and the investment community.

2015 Performance Highlights

Mr. Cowan played an integral role in the development and implementation of Suncor's financial strategies in support of Suncor's business and risk management objectives. His efforts in 2015 were focused on balancing increasing shareholder returns and investment in profitable growth while maintaining a strong financial position. Suncor's continued financial strength is a direct result of Mr. Cowan's careful stewardship of the company's financial position over the past year, which included the execution of strategies to increase liquidity, ensure financial flexibility and lower financing costs.

In his capacity as Chief Financial Officer, Mr. Cowan ensured Suncor maintained an unwavering focus on key priorities: capital discipline, cost management and profitable growth. He played a significant role in the development and execution of cost management and efficiency plans across the company. This included the announcement of a reduction of Suncor's capital budget by $1 billion, a reduction in the operational budget of $600 million to $800 million, and a reduction in the workforce of over 1,000 people. Reductions exceeded forecasts and the operating budget reduction was achieved in 2015, significantly ahead of the projected two year schedule. While delivering value to shareholders, this work ensured Suncor was effectively positioned to respond to lower commodity prices, as well as continue to progress key growth projects.

As part of an ongoing focus on continuous improvement, Mr. Cowan reviewed the structure and capacity of the Finance organization. This review resulted in changes in the leadership team, as well as the structure and size of the organization. These changes helped strengthen capacity and increase the function's efficiency and effectiveness.

Mr. Cowan was very active in helping to support the company's profile and relationships with key financial stakeholders. Over the course of 2015, he met with a wide range of key company stakeholders, and actively participated in conference calls, presentations and meetings with a range of investors, analysts, government and community leaders.

Total Direct Compensation. The corresponding chart displays Mr. Cowan's total direct compensation for the past two years.

Mark S. Little, Executive Vice President, Upstream

In January 2014, Mr. Little was named Executive Vice President, Upstream and became responsible for all operated, non-operated and joint venture production, including Oil Sands, In Situ, Exploration and Production, and the future operations of Fort Hills.

2015 Performance

2015 Goals

•
  Continue to drive safety improvement across upstream and throughout the Wood Buffalo region.
•
  Continue the journey to operational excellence across the upstream portfolio.
•
  Deliver production safely with improved environmental performance and lower unit costs.
•
  Drive to a world class start-up and operation of the Fort Hills project.
•
  Continue to progress key upstream investments to maximize shareholder value.

2015 Performance Highlights

Under Mr. Little's leadership, Suncor's Oil Sands Safety Task Force team (formed in 2014) developed and successfully implemented 16 safety-related solutions to drive safety improvements across the business in 2015. This important work placed a major focus on safety leadership and communications to reset the way all employees approach safety from senior leadership to the frontline. The renewed focus on safety led to the Oil Sands business having its best ever employee safety performance in 2015. As Chair of the Oil Sands Safety Association, Mr. Little championed the adoption of a new standard set of safety rules across the Wood Buffalo region to promote consistency across oil sands work sites in the area.

Mr. Little's continued focus on operational excellence in 2015 contributed significantly to Suncor's strength through the current commodity cycle. Total 2015 upstream production was up 8% from 2014 production to 577.8 mboe/d. This increase was primarily driven by increased Oil Sands operations production, which improved to 433.6 mbbls/d, an 11% increase over the last annual production record established in 2014. This improvement was achieved with minimal additional capital investment. Upgrading asset utilization also increased by more than 8% year over year to 91%, Suncor's best ever performance in this area.

Record production, combined with a reduction in absolute costs achieved, resulted in a nearly 18% year over year decrease in Oil Sands cash operating cost per barrel(1) to $27.85 in 2015; the lowest it has been since 2007. This was accomplished, in large part, through a sizeable restructure and a significant and unwavering focus on cost management.

In 2015, Mr. Little established a dedicated organization to continue driving towards a world-class Fort Hills project start-up. This team will work to ensure alignment with Suncor Base Plant processes and systems to leverage Suncor's experience as the operator of the project and drive efficiencies. Mr. Little's work on key upstream investments, such as the power facilities swap with TransAlta Corporation and the purchase of an additional working interest in the Fort Hills project, also resulted in enhanced shareholder value.

Mr. Little continued to improve on upstream environmental performance. Through his leadership, the business achieved several improvements in 2015 compared to the prior year, including a nearly 10% decrease in energy intensity, a 28% decrease in air emissions and a further 13% decrease in fresh water intake, which amounts to a 31% reduction since 2013.

•
  Effective execution of the Fort Hills project.
•
  Improve workforce productivity, competence and diversity.
•
  Enhance Suncor's reputation through participation in external efforts that contribute to industry collaboration, assure workforce competence and support labour needs.

2015 Performance Highlights

Through Mr. MacSween's leadership, Major Projects supported and delivered on approximately $5 billion of projects in 2015 that are expected to contribute tangible value to Suncor. The business continued to improve its RIF performance in 2015, achieving record results with special attention focused on serious, high-risk, high-potential incidents.

Mr. MacSween led broad implementation of the Asset Development and Execution Model – introduced in 2014 – and realization of organizational efficiencies implemented over the past two years. These efforts are intended to deliver value while improving safety and project quality. Mr. MacSween also ensured collaborative efforts such as 'safety summits' with project contractors reinforced Suncor's commitment to safety as well as fostered improvements in safety and productivity culture across all project sites.

Mr. MacSween has maintained an unwavering focus on ensuring the successful progress of the Fort Hills project. All critical milestones continue to be met for the project. Engineering is substantially complete and fabrication is well underway with equipment arriving at the project location. On site construction progress has surpassed 50% completion and is tracking to plan. Safety and environmental performance continues to track positively against project goals and relative to industry benchmarks. Significant progress has been made to align the transition of Fort Hills' assets from construction to operations. During 2015, the project and operations teams collaborated to safely hand over the first assets and systems including the wastewater treatment plant and Mount Logan Lodge, which provides accommodation for staff working at the Fort Hills site.

Collaboration continued with a broad range of industry organizations to identify opportunities and drive field productivity improvements across the sector. A number of pilot initiatives were started in 2015 in collaboration with engineering, procurement and construction contractors, fabricators and labour groups.

Mr. MacSween continues to be engaged in the community helping to enhance the company's reputation. He remains on the Board of Directors of Go Productivity (formerly Productivity Alberta); serves as chair of the Canadian Welding Bureau; and was a cabinet member for the third year with the Calgary United Way. In 2015 he also spoke about workplace diversity and productivity challenges at events in Calgary.

•
  Develop and maintain a culture of operational excellence in Suncor's commercial business activities and other stakeholder relationships, including suppliers and joint venture partners.
•
  Facilitate clear communication of Suncor's strategic intent to shareholders and other stakeholders.

2015 Performance Highlights

Mr. Reynish continued to guide Suncor's portfolio optimization throughout 2015. His efforts were focused on helping Suncor continue to add to its resource base, enhance its growth profile, reduce its reliance on third party operators and make asset divestments to position the company for long-term value creation. Key accomplishments in this area were guiding the acquisition of an additional 10% interest in the Fort Hills project, and the launch of an unsolicited offer for Canadian Oil Sands Limited.

As part of Suncor's capital discipline focus, Mr. Reynish played a lead role in the capital project review process that manages capital allocations throughout the Corporation.

Mr. Reynish continued to play an on-going role in achieving sustainable reductions in operating and overhead costs through his leadership of the supply chain function. This contributed to improving Suncor's competitiveness. Corporate-wide OS&G were reduced 10% during 2015. Contract re-negotiation and management initiatives to reduce costs were started in 2015 and will remain on-going through 2016.

As part of Suncor's logistics support function, Mr. Reynish provided oversight of material and manpower movements to operating sites. During 2015 this effort was specifically focused on Fort Hills project construction requirements to ensure it remained on schedule and on budget.

Mr. Reynish co-ordinated new technology developments within the company's business units and through Suncor's participation in industry partnerships such as COSIA throughout the year.

He also continued work to ensure company-wide understanding of corporate strategy, and joint venture structures and projects, as well as associated commercial opportunities and risks through a series of internal and external presentations. Delivering this information helped ensure close internal alignment on strategies and priorities. Mr. Reynish's efforts in this area were also effective in positioning the company externally to take advantage of strategic business opportunities.

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

Looking Ahead to 2016:

The HR&CC did not make any changes to the 2015 executive compensation structure for 2016.

No base salary increase budget was approved for executives or other employees. As a result, for 2016, annual base salaries for the NEOs and other executives will continue to be held at 2014 levels.

On February 3, 2016, the Board approved a grant of options and PSUs to the NEOs effective February 15, 2016, as displayed in the table below, under the terms of the SOP and the PSU Plan. The exercise price of these options is $30.21.

Name |  | Options |  | PSUs |

Executive Compensation Alignment with Shareholder Value

In an industry subject to commodity price cycles, Suncor's focus is on long-term shareholder value growth and ensuring returns to shareholders. Suncor's common shares were valued at $35.72 on the TSX at December 31, 2015, a decrease of approximately 3.2% over the year before. From 2010 to 2015, Suncor's share price decreased by approximately 6.7%. The following performance graph shows Suncor's cumulative TSR for the past five years. The total direct compensation of our NEOs over this period was generally aligned with the experience of shareholders, as a substantial portion of NEO total direct compensation is linked to Suncor's share price.

President and CEO Realizable Pay. The aggregate three-year realizable pay chart shows the President and CEO's realizable total direct compensation compared to his pay opportunity at December 31, 2015 for the three-year period from 2013 to 2015. The realizable pay value is approximately 11% below the pay opportunity level. The realizable pay level supports pay for performance alignment as the mid- to long-term value is in line with TSR performance compared to peers and absolute share price performance.

The table below compares the grant date value of total direct compensation (pay opportunity), as reflected in the Summary Compensation Table, to the President and CEO's realizable total direct compensation for the period 2013 to 2015 and displays the current value of $100 in compensation awarded in relation to the current value of $100 invested in Suncor's common shares at the beginning of the period indicated.

NEO Realizable Pay. The pay opportunity and realizable pay for total direct compensation for the NEOs over the period from 2013 to 2015 are shown in the chart below. Over this period, the realizable pay at December 31, 2015 for total direct compensation for the NEOs was approximately 14% lower than the pay opportunity, as determined in accordance with the methodology described in the footnotes for the Realizable Pay chart below. The lower realizable pay value for total direct compensation for the NEOs has been generally consistent with the trend of total return on investment indicated for Suncor in the performance graph provided above.

Suncor's strong operational performance during the period resulted in above target payouts under the AIP component of total direct compensation. At December 31, 2015, the value of annual mid- to long-term incentive awards granted between 2013 and 2015 was approximately 19% lower than the expected value, as determined in accordance with the methodology described in the footnotes for the Realizable Pay chart below. Two of the three stock option awards during the period had no value at December 31, 2015. The 2013 realizable pay is above the pay opportunity due to the higher than target vesting level for the 2013 PSUs reflecting Suncor's strong TSR performance relative to peers through the 2013-2015 period. This indicates the variability of performance contingent mid- to long-term compensation provided to the NEOs.

The lower current value at December 31, 2015 of the annual mid- to long-term incentive awards demonstrates alignment with Suncor's pay-for-performance philosophy, TSR performance relative to peers and absolute share price performance.

  Values for 2013 include those ascribed to Messrs. Williams, Little, MacSween and Reynish. Values for 2014 include those ascribed to Messrs. Williams, Cowan, Little, MacSween and Reynish.

President and CEO Look Back. The HR&CC follows good governance practice in annually reviewing a broader analysis of the total compensation earned and accruing to the President and CEO since his appointment and relating it to the TSR during the same period.

In its recent review, the HR&CC compared the total accrued compensation earned by the President and CEO since his appointment in 2012 up to December 31, 2015 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.

  For share-based awards, the fair value of awards at the grant date reflects the number of PSUs, RSUs or DSUs awarded multiplied by the grant price. We use this methodology for consistency with market practice and with the methodology used in competitive market analysis. For PSUs and RSUs, the grant price is calculated as the average of the high and low common share prices on the five trading days preceding the grant date. For DSUs, the grant price is calculated as the average of the high and low common share prices on the trading day preceding the grant date. For the grant prices of share-based awards granted to the NEOs, see Schedule D.

  Effective January 1, 2013, Suncor commenced valuing its option-based awards using the Black Scholes methodology, which is in accordance with International Financial Reporting Standards, for consistency with the accounting valuation. For option-based awards, the fair value of the awards at the grant date reflects the number of options awarded multiplied by the accounting fair value price. The fair value of the 2015 option award was $6.68. The fair value was calculated using the following assumptions: common share weighted average price of $38.86, expected life of 4.5 years, volatility of 27.9%, risk free rate of 0.65% and dividend yield of 2.85%. For information on the 2014 and 2013 options, refer to the Summary Compensation Table in Suncor's 2015 and 2014 management proxy circulars, respectively.

For Mr. Cowan, value includes $150,000 cash payment which is the remaining portion of a loss of compensation payment committed at hire in 2014. For Mr. Williams, value also includes the aggregate total of annual perquisites and other personal benefits consisting of a flexible perquisite allowance of $50,000 which is a taxable benefit that is paid in two installments semi-annually. With the exception of Mr. Williams, the aggregate amount of annual perquisites and other personal benefits did not exceed the lesser of $50,000 or 10% of the total annual salary for each NEO for the 2015 financial year and are not included in the All Other Compensation value.

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

In addition to the pension provided under the Suncor Energy Pension Plan, certain executive officers may receive supplemental retirement payments under the terms of the SERP. Under the terms of the SERP, any new participants must be approved by the HR&CC. Ten persons who are currently members of Suncor senior executive management were participants in the SERP as at December 31, 2015.

Quick Facts on SERP:

ü
  recognizes only Suncor service;
ü
  up-front accrual is a helpful attraction tool;
ü
  requires five years of executive employment for vesting;
ü
  recognizes remuneration to a maximum of two times base salary.

The SERP is a non-registered supplemental retirement arrangement designed to attract mid-career executives with a competitive career based pension that features an up-front accrual. This attraction element is balanced by features that limit the executive pension by: (i) requiring that an executive provide five years of service to be entitled to SERP benefits, which is five years more than the service required under the Suncor Energy Pension Plan; (ii) limiting service to Suncor related experience only, both for vesting and benefit accrual purposes; (iii) limiting the executive's total pension to 50%, unless there is total service greater than 25 years, in which case the maximum is 70% of executive remuneration; and (iv) limiting executive remuneration to a maximum of two times base salary (base salary plus annual incentive target bonus of up to 100% of base salary). All of the NEOs are members of the SERP. Additional details of the SERP follow.

•
  Executive employment commences at the date of entry into the SERP.
•
  The SERP pension is based on the executive's remuneration multiplied by a combined accrual rate of 5% per year of executive employment plus a pension formula percentage determined in respect of the Suncor Energy Pension Plan relating to service prior to becoming an executive, limited to a combined accrual rate of 50%. The pension increases by an additional 1.5% of the executive's remuneration for executive employment earned after the executive completes 25 years of service. The total pension is limited to 70% of the executive's remuneration, as described below.
•
  Executive remuneration is an annualized amount of the average salary plus target bonus for the best consecutive 36 months of the last 180 months of continuous service. Target bonus cannot exceed 80% of base salary for Senior Vice Presidents and Executive Vice Presidents and 100% for the CEO.
•
  Five years of executive employment including, where applicable, the period of notice of termination or payment in lieu of such notice, are required for rights under the SERP to vest. Executive officers with less than five years of executive employment are not eligible to receive supplemental retirement payments under the SERP except in the event of a change of control, or a loss of employment upon or after the occurrence of certain specified events.
•
  SERP payments for retirement prior to age 60 will be reduced by 5/12th of 1% for each month that the executive 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 executives, joint and survivor, with 50% to the non-member surviving spouse; and for single executives, for life, with ten years guaranteed.
•
  A portion of retirement income is payable by the Suncor Energy Pension Plan, including both the defined benefit and defined contribution components, and a portion is payable under the SERP. Canada Pension Plan payments are in addition to payments under the Suncor pension plans.
•
  Trust arrangements have been established to provide for the long-term funding of Suncor's non-U.S. taxpayer SERP obligations.

(1)
  For Mr. MacSween, credited service reflects executive employment of five years plus 15 years of service accrued under the Suncor Energy Pension Plan prior to becoming an executive.
(2)
  Represents the estimated annual pension, excluding any employee paid ancillary benefits and before any applicable early retirement reduction that would be received by the NEO based on actual pensionable service to the stated date and actual executive remuneration as at December 31, 2015.
(3)
  The defined benefit obligation is the estimated value of the pension obligation to the date indicated using the actuarial assumptions and methods that are consistent with those used in determining the pension obligation as disclosed by Suncor in its consolidated financial statements. See note 22 in Suncor's consolidated financial statements for the year ended December 31, 2015. The methods and assumptions used to determine the estimated amounts may not be identical to those used by other companies and as a result may not be directly comparable to the amounts disclosed by other companies.
(4)
  Compensatory change represents the increase (decrease) in the pension obligation for 2015 related to the annual service cost, compensation changes higher or lower than assumptions and the impact of plan changes, if any. This amount may fluctuate significantly from year-to-year as changes in compensation impact the pension obligation for all years of credited service.
(5)
  Includes items such as, but not limited to, interest on the obligation, changes in assumptions for future salary projections and changes to the discount rate.

Defined Contribution Plans. Under the combination provision of the Suncor Energy Pension Plan, applicable to Messrs. Williams, Cowan, Little, MacSween and Reynish, 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. All contributions to the defined contribution accounts are subject to maximum levels.

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

The following table summarizes the defined contributions accounts of each of the NEOs.

TERMINATION AGREEMENTS AND CHANGE OF CONTROL ARRANGEMENTS

Termination Agreements

Suncor has employment termination agreements with each of the NEOs.

Quick Facts on
Termination Agreements:

ü
  are in place with the President and CEO and nine of Suncor's other senior executives;
ü
  provide a 24-month notice period;
ü
  are "double trigger" on a change of control;
ü
  are reviewed annually by the HR&CC;
ü
  terms are updated periodically for agreements with new participants based on governance trends and best practice.

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

Notice Period Provisions. For the NEOs, should a Termination Event occur, the termination agreements provide a 24-month notice period. Cash payments are provided (i) for base salary and annual incentive during the notice period, (ii) for SOP (as defined on page 42) options which, but for the Termination Event, would have become exercisable during the notice period unless the NEO is eligible for retirement, in which case, under the terms of the SOP, unvested options would vest immediately and the option term would be reduced to the earlier of three years or expiry, and (iii) for PSUs and RSUs that would pay out during the notice period based on a performance factor calculated as at the date of termination unless the NEO is eligible for retirement, in which case the PSUs and RSUs would be held until the end of the performance or maturity period (in the case of RSUs) and paid per the terms of the PSU and RSU plans, and for Mr. Cowan that are pro-rated for the period he was employed during the grant period. The NEOs receive credited service under the SERP for the notice period.

Double Trigger Provisions and Change of Control. Suncor's termination agreements with the NEOs are "double trigger", and as such provide for payments based only upon involuntary termination or constructive dismissal on a change of control.

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

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

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

(1)
  In the case of all the NEOs, for termination with cause, no incremental value will be realized.
(2)
  Short-Term Incentives include incremental annual bonus entitlement.
(3)
  In the case of Mr. Cowan for termination (without cause), Long-Term Incentive includes the incremental value of "in-the-money" unvested option-based awards that vest during the notice period, calculated as the difference between the closing price of a Suncor common share on the TSX as at December 31, 2015 ($35.72) and the exercise price of the option. The options that would have vested during the notice period are not "in-the-money". Under a change of control with involuntary termination, Long-Term Incentive includes the incremental value of all "in-the-money" unvested option-based awards that vest at termination, calculated in the case of a termination (without cause) noted above, and the incremental value of PSUs and RSUs held, pro-rated for active period of time in plan, that vest at termination, calculated as per the applicable Plan. PSUs are based on the performance level at December 31, 2015.
(4)
  In the case of Messrs. Little and MacSween, for termination (without cause), Long-Term Incentive includes the incremental value of all "in-the-money" unvested option-based awards that vest during the notice period, calculated as the difference between the closing price of a Suncor common share on the TSX as at December 31, 2015 ($35.72) and the exercise price of the option, and the incremental value of PSUs held, calculated as per the PSU Plan and based on performance level at December 31, 2015. Under a change of control with involuntary termination, Long-Term Incentive includes the

60 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

incremental value of all "in-the-money" unvested option-based awards and the incremental value of PSUs held that vest at termination, calculated as in the case of a termination (without cause) noted above.

(5)
  In the event of termination (without cause) each NEO is granted an additional two years of pension service in respect of the notice period under the terms of their respective termination agreements. In addition, with a change in control, any non-vested NEOs would be immediately vested in the SERP. In the event of change in control (voluntary termination), immediate SERP vesting is the only benefit; there are no further incremental pension benefits payable under this scenario.
(6)
  In the event of their resignation, Messrs. Williams and Reynish are retirement eligible. The value includes the incremental value of all "in-the-money" unvested option-based awards held that vest as a result of their resignation. The values are calculated as the difference between the closing price of a Suncor common share on the TSX at December 31, 2015 ($35.72) and the exercise price of the option.
(7)
  Assumes involuntary termination on change of control.
(8)
  Assumes voluntary termination on change of control.
(9)
  Messrs. Cowan, Little and MacSween were not eligible for retirement as of December 31, 2015.
(10)
  In the case of Messrs. Williams and Reynish, value includes the incremental value of all "in-the-money" unvested option-based awards held that vest as a result of retirement, which they could voluntarily choose to do on a change of control. The values are calculated as the difference between the closing price of a Suncor common share on the TSX at December 31, 2015 ($35.72) and the exercise price of the option.

INDEBTEDNESS OF DIRECTORS, EXECUTIVE OFFICERS AND SENIOR OFFICERS

No current or proposed director, executive officer or employee of Suncor, or any former director, executive officer or employee of Suncor, or any associate of any of the foregoing, is, or has been at any time during 2015, excluding routine indebtedness, indebted to Suncor or its subsidiaries, either in connection with the purchase of Suncor securities or otherwise.

SUMMARY OF INCENTIVE PLANS

The following table sets forth information in respect of securities authorized for issuance under our equity compensation plans as at December 31, 2015.

Plan Category | Number of securities to be issued upon exercise of outstanding options (a) |  | Weighted-average exercise price of outstanding options ($) (b) |  | Number of securities remaining available for future issuance under equity compensation plans (excluding securities reflected in column (a)) (c) |
Equity compensation plans approved by security holders | 25 749 639 |  | 36.74 |  | 18 626 133 |
Equity compensation plans not approved by security holders | 3 340 008 |  | 45.53 |  | — |
Total | 29 089 647 |  | 37.75 |  | 18 626 133 |

The numbers shown beside "Equity compensation plans approved by security holders" refer to options granted under the SOP, the closed Suncor Executive Stock Plan (the "ESP") and the closed Petro-Canada Employee Stock Option Plan (the "PCSOP"). The numbers shown beside "Equity compensation plans not approved by security holders" refer to the closed Suncor Key Contributor Stock Option Plan (the "SKCSO").

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 61

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

Options entitle the holder to purchase Suncor common 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 Suncor common share on the date of grant. The options and SARs generally have a term of seven years with a vesting schedule of one third per year over three years. "Market Value" means the simple average of the daily high and low prices at which Suncor common shares were traded in one or more board lots on the TSX over the five trading days immediately preceding the date of grant or exercise date, as the case may be. The exercise price of each option granted cannot be less than the fair market value of a common share at the time of grant.

Due to legislative changes in 2010 under the Income Tax Act (Canada), Suncor no longer grants SARs or tandem SARs to Canadian employees.

Performance Share Unit Plan. PSUs form a minimum of 50% of the equity component of target total direct compensation for executives. A PSU award may pay out based on a vesting level between 0% and 200% of the number of PSUs initially awarded contingent upon Suncor's performance relative to a peer group of companies over a three-year period. PSUs provide for notional dividend re-investment.

The selection of peer group companies for a PSU grant is based on a variety of criteria including size (revenue and market capitalization), industry and business scope (integrated and exploration and production companies), oil weighting, beta and stock behavior. The selection criterion is reviewed periodically and approved by the HR&CC. The PSU peer group is reviewed annually for new grants, adjusted as appropriate and approved by the HR&CC.

The peer group and related information for the 2014 and 2015 PSU awards are displayed below.

Anadarko Petroleum Corporation |  | Chevron Corporation |  | Husky Energy Inc. |
Apache Corporation |  | ConocoPhillips |  | Imperial Oil Limited |
BP plc |  | Devon Energy Corporation |  | Marathon Oil Corporation |
Canadian Natural Resources Limited |  | EOG Resources Inc. |  | Occidental Petroleum Corporation |

Vesting of PSU awards is determined based on Suncor's TSR relative to peer companies and its resulting company grouping rank as displayed in the table below.

Company TSR Rank |  | Performance Factor (% of PSUs vesting) |
1-3 |  | 200% |
4-5 |  | 175% |
6-7 |  | 150% |
8-9 |  | 100% |
10-11 |  | 75% |
12-13 |  | 50% |
14 and below |  | 0% |

Following a robust process, at the end of the three-year performance period, TSR is measured, company grouping rank and performance factor are determined and, if applicable, a payout is made to participants in cash. The final payout value is based on the number of vested PSUs (including dividend equivalents) multiplied by the market price of a Suncor common share, as calculated under the PSU Plan provisions.

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

PSU Grant Year |  | Vesting Level |
2004 |  | 100% |
2005 |  | 100% |
2006 |  | Bottom Quartile / 0% |
2007 |  | Bottom Quartile / 0% |
2008 |  | Bottom Quartile / 0% |
2009 |  | 112% |
2010 |  | 111% |
2011 |  | 57% |
2012 |  | 135% |
2013 |  | 200% |

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 at the compliance date.

Restricted Share Unit Plan. The RSU Plan was established in January 2009 by the HR&CC. Under the plan, RSUs may be granted to key employees, senior managers and executives of Suncor as part of their competitive compensation and to support attraction and retention. As RSU value is tied directly to Suncor's share price, RSUs serve 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 common share price for the last 20 trading days of the restricted period. Grants under the RSU Plan are administered by the HR&CC. RSUs do not count towards the assessment of executive share ownership levels for purposes of the share ownership guidelines. The RSU Plan was amended in 2009 to provide for notional dividend reinvestment for grants after January 1, 2010.

(1)
  All plans closed effective August 1, 2009.
(2)
  Period of time from grant date until maximum expiry. Where no period indicated, award will be automatically redeemed no later than 23 months following termination of employment, unless redeemed earlier under the terms of the respective plan.
(3)
  This plan allowed eligible employees (as that term is defined in the plan) to elect to have their bonus payable in the next calendar year in DSUs.
(4)
  Members (as that term is defined in the plan) could elect to receive all or a portion of their annual Board retainer and meeting fees in DSUs.
(5)
  The PCSAR Plan provides a cash payment to participants equal to the appreciation in share price between the date the SARs were granted and the date the SARs are exercised. All SARs are non-transferable and non-assignable, and exercisable on terms determined by the Management Resources and Compensation Committee of Petro-Canada in its discretion at the time the SARs were granted. The exercise price per SAR cannot be less than the closing price of the common shares on the TSX on the day preceding the day the SAR was granted.

Aggregate Potential Dilution. The aggregate potential dilution of all issued, outstanding and authorized options under Suncor stock option plans was 3.0% at February 22, 2016. Suncor has no other equity compensation plans involving newly issued securities.

2015 Grant Rate (Run Rate): Stock options granted under the SOP in 2015 of 7,131,800 totaled less than 1% (approximately 0.5%) of shares outstanding at the end of 2015.

Additional Terms of Equity Compensation Plans.

Issuance of Shares under Plans

•
  No one person or company is entitled to receive more than 5% of the issued and outstanding Suncor common shares pursuant to all equity-based compensation arrangements.

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

Amendment

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

64 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

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

Impact of Change of Control, Reorganization or Other Event Affecting the Corporation

•
  Suncor's equity compensation 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 Suncor common shares.

•
  Upon a change of control, awards that have been granted under the SOP that remain outstanding on the change of control will be substituted with new awards on substantially the same terms and conditions. Provided the foregoing occurs, a holder's options will not vest upon or in connection with a change of control unless his or her employment is terminated within 12 months of the change of control (other than for cause), in which case the options will vest upon the holder's termination and shall expire three months following the termination date. However, where options that remain outstanding on a change of control are not substituted with new awards on substantially the same terms and in certain other circumstances (including at the discretion of the Board), the outstanding awards will immediately become exercisable. Any award not so exercised will expire at the closing of the change of control transaction.

Termination of Employment

•
  Pursuant to the SOP, in the event of an employee's involuntary termination (other than for cause, death, permitted leave, retirement or in connection with a change of control) or voluntary termination of employment, unvested options expire immediately and vested options expire no later than three months from such termination. In the event of the holder's death, all options become exercisable by the holder's estate and shall expire no later than 12 months after the date of death. In the event of the holder's retirement, all options become exercisable and shall expire no later than 36 months after the date of retirement. If a holder is absent from work as a result of a permitted leave, the holder's options shall continue to vest for a period of 24 months from the date of commencement of the leave and the right to exercise such holder's options shall terminate no later than the expiration of 12 months from the date that is 24 months from the date of commencement of the leave. If the holder has not returned to active service prior to the expiration of 24 months from the date of commencement of the permitted leave then the holder's options which were not exercisable 24 months from the date of commencement of such leave shall immediately terminate. In the event of involuntary termination for cause, all options expire on the date of such termination.

CLAW BACK POLICY

The Board approved the adoption of a claw back policy for Suncor in 2012. Under the claw back policy, in situations where: (i) the amount of incentive compensation received by an executive officer or former executive officer to whom the policy applies was calculated based or contingent upon the achievement of certain financial results that were subsequently the subject of or affected by a material restatement of all or a portion of the company's financial statements; and (ii) the executive officer or former executive officer engaged in intentional misconduct or fraud that caused, or potentially caused, the need for the restatement, as admitted by the executive officer or, in the absence of such admission, as determined by a court of competent jurisdiction in a final judgment that cannot be appealed; and (iii) the incentive compensation payment received would have been lower had the financial results been properly reported, then the Board may, to the extent permitted by applicable laws and to the extent it determines that it is in the company's best interest to do so, require reimbursement of the amount by which the after-tax incentive compensation received by such executive officer under the company's annual and long-term incentive plans exceeded that which the executive officer would have received had the financial statements not been materially restated.

DIRECTORS' AND OFFICERS' INSURANCE

Under policies purchased by Suncor, approximately US$200 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 2015, Suncor paid premiums of approximately US$1.7 million for directors and officers insurance for the 12-month period ending July 1, 2016.

ADVANCE NOTICE BY-LAW

In 2015, shareholders confirmed Amended and Restated By-Law No. 2, A By-law Relating to Advance Notice of Nominations of Directors of the Corporation ("By-Law No. 2"), which establishes a framework for advance notice of nominations of persons for election to the Board. By-Law No. 2 sets deadlines for a certain number of days before a shareholders' meeting for a shareholder to notify the Corporation of his, her or its intention to nominate one or more directors, and explains the information that must be included with the notice for it to be valid. By-Law No. 2 applies at an annual meeting of shareholders or a special meeting of shareholders that was called to elect directors (whether or not also called for other purposes), and may be waived by the Board. It does not affect the ability of shareholders to requisition a meeting or make a proposal under the Canada Business Corporations Act.

In the case of an annual meeting of shareholders, notice must be given to the Corporation not less than 30 days prior to the date of the meeting; provided, however, that if the meeting is to be held on a date that is less than 50 days after the date on which the first public announcement of the date of the meeting was made, notice shall be made not later than the close of business on the tenth day following such public announcement. In the case of a special meeting (which is not also an annual meeting) of shareholders, notice must be given not later than the close of business on the fifteenth day following the date on which the first public announcement of the date of the meeting was made. In the case of an annual meeting of shareholders or a special meeting of shareholders called for the purpose of electing directors (whether or not also called for other purposes) where notice and access is used for delivery of proxy related materials, notice must be given not less than 40 days prior to the date of the meeting (but in any event, not prior to the date on which the first public announcement of the date of the meeting was made); provided, however, that if the meeting is to be held on a date that is less than 50 days after the date of such public announcement, notice shall be made, in the case of an annual meeting of shareholders, not later than the close of business on the tenth day following the date on which the first public announcement of the date of the meeting was made and, in the case of a special meeting of shareholders, not later than the close of business on the fifteenth day following the date of such public announcement. Shareholders

should consult the full text of By-Law No. 2, which is available on Suncor's web site at www.suncor.com and has been filed on SEDAR at www.sedar.com and on EDGAR at www.sec.gov.

As at the date of this management proxy circular, the Corporation had not received any additional director nominations.

CORPORATE GOVERNANCE

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

Suncor is a Canadian reporting issuer. Our common shares are listed on both the TSX and the New York Stock Exchange ("NYSE"). Accordingly, our corporate governance practices reflect applicable rules and guidelines adopted by the Canadian Securities Administrators (the "Canadian Requirements") and the U.S. Securities and Exchange Commission ("SEC"), including applicable rules adopted by the SEC to give effect to the provisions of the Sarbanes Oxley Act of 2002 (collectively, the "SEC Requirements"). NYSE corporate governance requirements are generally not applicable to non-U.S. companies. However, Suncor has reviewed its practices against the requirements of the NYSE applicable to U.S. domestic companies ("NYSE Standards"). Based on that review, Suncor's corporate governance practices in 2014 and 2015 did not differ from the NYSE Standards in any significant respect, with the exceptions described in Schedule E to this management proxy circular under the heading, "Compliance with NYSE Standards".

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

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

Risks, uncertainties and other factors that could influence the financial and operating performance of all of Suncor's operating segments and activities include, but are not limited to, changes in general economic, market and business conditions, such as commodity prices, interest rates and currency exchange rates; fluctuations in supply and demand for Suncor's products; the successful and timely implementation of capital projects, including growth projects and regulatory projects; competitive actions of

68 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

other companies, including increased competition from other oil and gas companies or from companies that provide alternative sources of energy; labour and material shortages; actions by government authorities, including the imposition or reassessment of taxes or changes to fees and royalties, such as the Notices of Reassessment ("NORs") received by Suncor from the Canada Revenue Agency, Ontario, Alberta and Québec, relating to the settlement of certain derivative contracts, including the risk that: (i) Suncor may not be able to successfully defend its original filing position and ultimately be required to pay increased taxes, interest and penalty as a result; or (ii) Suncor may be required to post cash instead of security in relation to the NORs; changes in environmental and other regulations; the ability and willingness of parties with whom we have material relationships to perform their obligations to us; outages to third party infrastructure that could cause disruptions to production; the occurrence of unexpected events such as fires, equipment failures and other similar events affecting Suncor or other parties whose operations or assets directly or indirectly affect Suncor; the potential for security breaches of Suncor's information systems by computer hackers or cyberterrorists, and the unavailability or failure of such systems to perform as anticipated as a result of such breaches; our ability to find new oil and gas reserves that can be developed economically; the accuracy of Suncor's reserves, resources and future production estimates; market instability affecting Suncor's ability to borrow in the capital debt markets at acceptable rates; maintaining an optimal debt to cash flow ratio; the success of the company's risk management activities using derivatives and other financial instruments; the cost of compliance with current and future environmental laws; risks and uncertainties associated with closing a transaction for the purchase or sale of an oil and gas property, including estimates of the final consideration to be paid or received, the ability of counterparties to comply with their obligations in a timely manner and the receipt of any required regulatory or other third party approvals outside of Suncor's control that are customary to transactions of this nature; and the accuracy of cost estimates, some of which are provided at the conceptual or other preliminary stage of projects and prior to commencement or conception of the detailed engineering that is needed to reduce the margin of error and increase the level of accuracy. The foregoing important factors are not exhaustive.

Many of these risk factors and other assumptions related to Suncor's forward-looking statements are discussed in further detail in Suncor's AIF, its MD&A, Form 40-F and other documents it files from time to time with securities regulatory authorities. Copies of these documents and Suncor's audited consolidated financial statements for the year ended December 31, 2015 are available without charge from Suncor at 150 – 6th Avenue S.W., Calgary, Alberta T2P 3E3, by calling 1-800-558-9071, or by email request to info@suncor.com or by referring to the company's profile on SEDAR at www.sedar.com or EDGAR at www.sec.gov. Except as required by applicable securities laws, Suncor disclaims any intention or obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Financial information in this management proxy circular is reported in Canadian dollars, unless otherwise noted, and is provided in Suncor's audited consolidated financial statements for the year ended December 31, 2015 and the MD&A, which are included in our 2015 Annual Report. Production volumes are presented on a working-interest basis, before royalties, unless otherwise noted. Certain financial measures in this management proxy circular – namely operating earnings, Oil Sands cash operating costs, CFOPS and ROCE – are not prescribed by Canadian GAAP. Operating earnings and Oil Sands cash operating costs are defined in the Advisories – Non-GAAP Financial Measures section of the MD&A and reconciled to GAAP measures in the Financial Information and Segment Results and Analysis sections of the MD&A. ROCE and CFOPS are defined and reconciled to GAAP measures in the Advisories – Non-GAAP Financial Measures section of the MD&A. ROCE, for the purposes of the table on page 40 of this management proxy circular, has been further adjusted to take into account adjustments made for decisions related to asset impairments (including Libya, Joslyn, White Rose and Golden Eagle). These non-GAAP financial measures are included because management uses the information to analyze business performance, leverage and liquidity. These non-GAAP financial measures do not have any standardized meaning and therefore are unlikely to be comparable to similar measures presented by other companies. Therefore, these non-GAAP financial measures should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP.

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 69

SCHEDULE A: SHAREHOLDER PROPOSAL NO. 1

The following shareholder proposal was submitted by NEI Investments for consideration at the meeting. This proposal and its supporting statement represent the views of the shareholder submitting them. Suncor is required by applicable law to set forth the shareholder proposal and the related supporting statement in its management proxy circular.

For the reasons set forth below in the "Board and Management Statement", the Board and management recommend that shareholders vote FOR this proposal.

Shareholder Proposal and Supporting Statement

Proposed Resolution

Be it resolved that:

Suncor provide ongoing reporting on how it is assessing, and ensuring, long-term corporate resilience in a future low-carbon economy. Specifically, reporting could be stand-alone or integrated into current company reporting mechanisms and could address Suncor's technology pipeline, emission reduction targets and performance, innovation and energy diversification strategies, provide a narrative on any stress-testing done against external low carbon scenarios (e.g. IEA's 450 and 2°C Scenarios), and other relevant strategies.

Shareholder Statement

For Suncor to remain an industry leader and continue to provide sustained returns to investors it will need to navigate various emerging constraints related to the global ambition to move to a low carbon economy. These constraints include, but are not limited to:

•
  Increased stringency of carbon regulations;
•
  Alberta's stated ambition to limit emissions from the oil sands to 100 Mt;
•
  Increasing competitiveness of renewables and explicit government goals to increase market share of renewable/low carbon energy;
•
  Potential demand destruction from increased efficiency and more stringent regulations;
•
  Concerns from First Nations and stakeholders about the perceived high-carbon nature of oil sands production;
•
  Suncor's increasing absolute GHG emission trend

The risk of stranded assets in the fossil fuels sector has been raised by notable institutions such as Standard & Poors, Goldman Sachs and the Bank of England. Many investors are already acting on these concerns in regard to thermal coal operations, while major banks (such as Citigroup, Bank of America and Credit Agricole SA) are explicitly scaling back credit exposure to the coal industry based largely on climate concerns. The oil sands is widely perceived as a high-carbon, high-cost resource and will likely face similar pressure absent significant developments.

Suncor has many elements of a sound GHG management strategy in place, and has been an early mover on this issue relative to its peers. As a result, it is well placed to leverage these strengths, which include, but are not limited to:

•
  Industry leading disclosure on GHG emissions management;
•
  Carbon price stress testing for all new projects;
•
  Active participation in carbon offsets market;
•
  Profitable renewable energy investments in wind and biofuels;
•
  Strong research & development program with clear path to deployment for incremental and game-changing technologies;

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 A-1

•
  Leader in industry collaborations (such as COSIA);
•
  Vocal support for the implementation of carbon policy;
•
  Ongoing investment in operational excellence and increased efficiency;
•
  Strong First Nations and stakeholder engagement efforts

Notwithstanding the company's efforts, there remains some uncertainty in the face of these challenges. Suncor investors would benefit from understanding how the company's strategy positions the company to transition to, and prosper in, a low carbon future. Suncor's CEO has stated that Suncor needs to be the "last guy standing" in a world with low oil prices and increased carbon reduction expectations.(1) Regular reporting on how Suncor is progressing against this goal would provide investors with assurance that key risks are being mitigated and position the company as a long-term energy investment of choice.

Board and Management Statement

Suncor's Board and management recommend voting FOR this proposal for the following reasons:

Suncor believes our energy system is in an era of change. As we try to meet growing global demand, energy experts continue to expect that hydrocarbons will continue to be a key source of reliable and affordable energy for the foreseeable future, while alternative and renewable energy sources become a greater part of the energy mix. Since hydrocarbons are finite resources with an environmental impact, it will be critical to use them wisely as the world transitions to lower carbon sources of energy.

Suncor believes that it has a responsibility to address the environmental impacts of its operations and it strives to continuously raise the bar on environmental performance.

Oil sands and oil development have an important role to play in meeting our energy needs. As Canada's largest integrated energy company, Suncor recognizes that it has a responsibility to think about its role in the energy system transition and how we can work together with broader society on our energy future.

Suncor has a long, well-established track record of being a leader on climate change issues dating back to the issue of its Seven Point Climate Change Plan in 1997. In recent years, Suncor has called for a carbon levy (2011), taken a leadership role in Canada's EcoFiscal Commission and called for an economy-wide price on carbon (2015).

Suncor continues to play a leading role in developing long-term alternative bitumen extraction technologies that could result in significantly reducing the greenhouse gas emissions intensity of oil sands production. The company works with several organizations to achieve further carbon intensity reductions and advance potential long-term climate change solutions.

Suncor appreciates that shareholders and other stakeholders benefit from understanding how the company is addressing these challenges. Suncor already provides extensive reporting on its efforts in these areas in its annual Report on Sustainability, its submissions to several third party sustainability indices and climate change reporting organizations and its Annual Information Form/Form 40-F. Suncor believes the additional disclosures referred to in this proposal will provide the company with the opportunity to continue to engage with shareholders and other stakeholders about its initiatives in this area in a way that is both meaningful and informative as well as being a productive use of its resources. Therefore, the Board and management recommend shareholders vote FOR this proposal.

A-2 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

SCHEDULE B: SHAREHOLDER PROPOSAL NO. 2

The following shareholder proposal was submitted by a group of shareholders for consideration at the meeting. This proposal and its supporting statement represent the views of the shareholders submitting them. Suncor is required by applicable law to set forth the shareholder proposal and the related supporting statement in its management proxy circular.

For the reasons set forth below in the "Board and Management Statement", the Board and management recommend that shareholders vote AGAINST this proposal.

Shareholder Proposal and Supporting Statement

Resolved, the shareholders of Suncor Energy Inc. ("Suncor") request the preparation of a report, updated annually, disclosing:

1.
  Suncor policy and procedures governing lobbying, both direct and indirect, and grassroots lobbying communications.
2.
  Payments by Suncor used for (a) direct or indirect lobbying or (b) grassroots lobbying communications, in each case including the amount of the payment and the recipient.
3.
  Description of management's and the board of directors' decision making process and oversight for making payments described in sections 2 and 3 [sic] above.

For the purposes of this shareholder proposal, a "grassroots lobbying communication" is a communication directed to the general public that (a) refers to specific legislation or regulation, (b) reflects a view on the legislation or regulation and (c) encourages the recipient of the communication to take action with respect to the legislation or regulation.

"Indirect lobbying" is lobbying engaged in by a trade association or other organization of which Suncor is a member. Both "direct lobbying" and indirect lobbying" [sic] and "grassroots lobbying communications" include efforts to influence public policy at the local, provincial and national levels.

The report shall be presented to the Audit Committee or other relevant Suncor oversight committees and posted on Suncor's website.

Supporting Statement

As shareholders, we encourage transparency and accountability in Suncor's use of corporate funds to influence legislation and regulation. In 2014 Suncor together with its trade associations ranked second among public companies in their lobbying of the federal government (source: http://www.bnn.ca/News/2015/1/30/Playing-politics-with-shareholder- money-What-you-may-not-know.aspx) This does not include lobbying to influence policy in provincial and local jurisdictions, and Suncor lobbied the Alberta government on no less than twenty policy issues in the 6 months ending November 19, 2015.

Suncor is a member of the Canadian Association of Petroleum Producers (CAPP), Canadian Fuels Association, Mining Association of Canada, Alberta Chamber of Resources, Canadian Council of Chief Executives, Energy Policy Institute of Canada, and World Business Council for Sustainable Development. Suncor does not disclose its memberships in, or payments to, trade associations, or the portions of such amounts used for lobbying. Members of CAPP pay up to $2.6 million in annual membership fees (source: http://www.thestar.com/news/atkinsonseries/2015/09/04/oil-industry- association-a-powerful-lobby-in-ottawa.html).

Payments to organizations that pursue agendas contrary to Suncor's stated goal of being "an industry leader in sustainable development by continued performance improvements in air emissions, water withdrawals, land reclamation and energy efficiency" may pose additional risks to shareholder value (http://sustainability.suncor.com/2015/en/environment/environment.aspx). Transparent reporting would reveal whether company assets are being used for objectives contrary to Suncor's long-term interests.

Lobbying expenditures can potentially involve Suncor in controversies posing reputational risks. For example, CAPP was associated with the scandal involving Bruce Carson, former advisor to the prime minister who was prosecuted for influence peddling and improper lobbying (source: http://thetyee.ca/News/2015/10/05/Canada-Biggest-Unheard-Political- Scandal/).

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 B-1

Grassroots lobbying is another type of lobbying expenditure that Suncor does not disclose. CAPP's attempts at grassroots lobbying may pose reputational risk for its members, including Suncor (source: http://www.theglobeandmail.com/news/british-columbia/raise-your-hand-if-you-think-a-big-oil-spill-couldnt-happen-in-vancouver/article24584494/).

We encourage our Board to require comprehensive disclosure related to direct, indirect and grassroots lobbying.

Board and Management Statement

Suncor's Board and management recommend voting AGAINST this proposal for the following reasons:

Suncor participates in public policy discussions on a wide range of issues relevant to the company's business and regularly communicates with governments in jurisdictions where it operates. Suncor believes that open dialogue between government, stakeholders and industry leads to improved government decision-making, thereby benefitting shareholders, as well as all other stakeholders. Through the company's engagement activities, Suncor aims to decrease the probability of ad hoc or reactive policy development by working to achieve a balanced approach.

Suncor also participates in industry groups representing the interests of both the energy industry and the broader business community and in doing so promotes the public policy objectives important to Suncor, its shareholders and other stakeholders. However, Suncor's participation as a member of these organizations comes with the understanding that Suncor may not always support every position taken by these organizations or their members.

Suncor is committed to adhering to the highest ethical standards with respect to communications with government officials. The Corporation ensures it complies with all laws respecting lobbying and political contributions, and reports government interactions consistent with the law and company policies. Suncor has in place a policy respecting communicating with government officials that sets out stringent requirements to ensure that any political contributions and communications with government officials comply with all laws and are in line with Suncor's corporate strategy, corporate code of conduct, and values.

Suncor agrees that transparency and accountability are important aspects of corporate lobbying activity. The Corporation's current public disclosures provide shareholders and other stakeholders with extensive information about Suncor's political activities. Shareholders can learn more about the topics Suncor is discussing with governments by consulting publicly accessible, online registries. Suncor files detailed reports on the Canadian federal lobbying registry, as well as on provincial lobbying registries in Alberta, British Columbia, Newfoundland and Labrador, Ontario and Québec describing lobbying activities and the company officials involved in such activities. Suncor also reports individual interactions with senior federal officials each month as required by legislation. In addition, Suncor publicly discloses its policy priorities. For example, Suncor reports its significant areas of policy engagement on climate change issues as well as Suncor's policy support and alignment with various associations' policy positions in an annual, publicly available report to a third party climate change organization.

Suncor employees follow a rigorous process prior to any planned communication with a government official on behalf of the company. This process includes a requirement that employees engaged in such communications first complete a training program regarding laws, company policies and ethical considerations relating to such activities; obtain approval from management before beginning to engage with government; and disclose to the company's government relations personnel any potential conflicts of interest.

Suncor's Board and management are confident that the company's lobbying activities are aligned with its shareholders' long-term interests. Effectively engaging with government, in a transparent manner, can lead to better public policy decisions and lower overall costs, which benefits shareholders and the broader public as a whole. Given the current extensive disclosure described above, Suncor's Board and management believe that shareholders have sufficient information available to determine the nature and scope of Suncor's lobbying activities and that a special report beyond Suncor's current voluntary and mandatory disclosures is an unnecessary and inefficient use of Suncor's resources. Therefore, the Board and management recommend shareholders vote AGAINST this proposal.

D-2 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

SCHEDULE E: CORPORATE GOVERNANCE SUMMARY

Throughout this summary, there are references to information available on the Suncor Energy Inc. ("Suncor" or the "Corporation") web site(1). All such information is available at www.suncor.com under the "About Us – Governance" tab. In addition, shareholders may request printed copies of these materials by contacting Suncor at the address on the back of the circular, by calling 1-800-558-9071 or by email request to info@suncor.com.

Board of Directors – Composition and Independence

The cornerstone of Suncor's governance system is its board of directors (the "Board"), whose duty is to supervise the management of Suncor's business and affairs. The composition of the Board and its independence are important elements of this system. Steven W. Williams, Suncor's President and Chief Executive Officer ("CEO"), is the only member of the Board who is not independent. Following the annual general meeting and assuming that all nominees for director are elected as contemplated in the Circular, 11 of 12 members (91.7%) of the Board will be independent directors. A short biography of each individual standing for election to the Board can be found starting on page 7 of the Circular.

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

Suncor's independent directors meet in-camera at the beginning and end of each Board and committee meeting without Mr. Williams or any other member of management present. The Board sessions are presided over by James W. Simpson, Suncor's independent Board chair, and the committee sessions by the independent chairs of the respective committees. The applicable chair or other independent director then communicates to management any issues or matters discussed at the in-camera meetings requiring management attention.

The Board has approved written position descriptions for the Board chair and Board committee chairs, which are available on Suncor's web site. The position description for the Board chair is also set out in Schedule F. These position descriptions supplement the Terms of Reference, as defined below. The position descriptions are reviewed annually by the Governance Committee. Any changes to the position descriptions are recommended by that committee to the full Board.

On an annual basis, the Board reviews and assesses the independence of its members in accordance with criteria it has adopted for this purpose. The Board's independence policy and criteria include a description of certain relationships that operate as a complete bar to independence as well as additional requirements applicable to members of the Audit Committee. Suncor's independence criteria, which are set out in Schedule G, are consistent with the Canadian Requirements and the SEC Requirements (each defined on page 67 of the Circular).

"Following the annual general meeting and assuming that all nominees for director are elected as contemplated in the Circular, 11 of 12 members (91.7%) of the Board will be independent directors. All of the members of the committees of the Board are independent."

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

(1)
  Information contained on or otherwise accessible through Suncor's web site, though referenced herein, does not form part of and is not incorporated by reference into this Schedule or the management proxy circular (the "Circular") to which this schedule is attached.

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 E-1

Some of Suncor's directors sit on the boards of other public companies, the particulars of which are set out on pages 7 to 12 of the Circular. The only directors who sit together on the board of another entity are Mr. Wilson and Ms. Côté, who are both directors of Finning International Inc. The Board has determined that this board interlock does not impair the ability of these directors to exercise independent judgment as members of the Board.

Some members of the Board are involved with companies with which Suncor has business relationships. The Board has reviewed these relationships on a case-by-case basis against the independence criteria and has determined that none of these relationships impair the independence of the individual directors: (i) as the directors do not serve as employees or executives of these other companies, their respective remuneration from these directorships is not personally material to them nor is it dependent on or variable with the nature or extent of the business relationship with Suncor; (ii) any business relationship with Suncor is not material to Suncor or the other company; and (iii) 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 precludes these directors from voting with respect to any contract or transaction where a potential conflict of interest could exist, should they be considered by the Board (see "Conflicts of Interest" on page E-10 of this Schedule).

"The Board has adopted Terms of Reference, which include a board mandate."

Terms of Reference

The Board has adopted terms of reference (the "Terms of Reference"), which serve as the charter of the Board. The Terms of Reference are reviewed by the Board at least annually. They include a general overview of the Board's role in Suncor's governance, a statement of key guidelines and policies applicable to the Board and its committees, and a mandate that describes its major responsibilities, goals and duties. These major responsibilities, goals and duties range from specific matters, including those that by law must be exercised by the Board, such as the declaration of dividends, to its general role to determine, in broad terms, the purposes, goals, activities and general characteristics of Suncor and its business. The Terms of Reference provide that the Board is responsible for the selection, monitoring and evaluation of executive management and for overseeing the ways in which Suncor's business and affairs are managed, thereby assuming responsibility for the stewardship of Suncor. The full text of the Terms of Reference is set out in Schedule H.

The Board discharges certain of its responsibilities through its four standing committees: the Audit Committee, the EHS&SD Committee, the Governance Committee and the Human Resources and Compensation Committee ("HR&CC"). Each committee has a written mandate, which it reviews annually and updates as appropriate. Any proposal to amend the mandates is reviewed by the Governance Committee for recommendation to the Board. There were no material amendments to any committee mandate in 2015.

The Governance Committee, with input from the Board chair, makes recommendations to the Board regarding committee appointments. In considering the appointment of members to Board committees, the Governance Committee and the Board endeavour to include directors of diverse backgrounds and at least one director with expertise and experience relevant to the committee's key roles.

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

The committees also have the authority to conduct independent investigations into matters that fall within the scope of their responsibilities and may engage external advisors (as may the full Board or an individual director), at Suncor's expense, to assist them in fulfilling their mandate.

For a summary of the key functions, roles and responsibilities of Board committees, see "Board Committees" on page E-6 of this Schedule.

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

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

The following is a description of some key duties of the Board as set out in the Terms of Reference. For more

E-2 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

information, please refer to the "Board Committees" section on page E-6 of this Schedule, the Terms of Reference set out in Schedule H and the mandates of the Board committees, available on Suncor's web site.

Ethics. The Terms of Reference require the Board, through the CEO, to establish Suncor's standards of conduct, including the Corporation's general moral and ethical tone and compliance with applicable laws. The CEO in turn is accountable for setting a high ethical tone and fostering a culture of integrity throughout the organization. The Board plays an active role in ensuring a high standard of corporate ethics and integrity through its oversight of Suncor's standards of business conduct code (the "Code") and compliance program (see "Ethical Business Conduct" on page E-9 of this Schedule), and through its assessment and evaluation of the performance of the CEO.

Strategic Planning. One of the Board's major duties is to review with management Suncor's mission, objectives and goals and the strategies and plans for achieving them. The Board also monitors Suncor's progress toward its strategic goals and plans, and revises Suncor's direction where warranted.

The Board is continually updated on the human, technological and capital resources required to implement Suncor's strategies and any regulatory, environmental, social, cultural or governmental constraints that may impact Suncor in carrying out its business objectives. Where instructive, this includes a competitive analysis of Suncor against its peers in different facets of its business. The Governance Committee acts as a sounding board for management on key strategic initiatives, and ensures that timely Board reviews of these initiatives occur throughout the year.

In addition to the Board's ongoing stewardship over Suncor's strategy, the Board holds a meeting annually which is devoted solely to strategy. The Governance Committee works with management to design this annual strategy meeting, and following the meeting, assesses its effectiveness.

The Board is also responsible for ensuring Suncor has an effective strategic planning process, and on an annual basis reviews Suncor's annual business plan (including Suncor's annual capital budget) and in doing so endorses the strategies reflected in Suncor's long range plan. The Governance Committee provides assistance to the Board by annually assessing Suncor's planning and budgeting processes.

Risk Oversight. The Board oversees Suncor's Enterprise Risk Management Program (the "ERM Program"). In accordance with the ERM Program, senior management, including the CEO, undertakes an entity-wide process to identify, classify, assess and report on the significant risks to Suncor's business and management's strategies to address risk.

The Board ensures there are systems in place to effectively identify, monitor and manage the principal risks of Suncor's business, and to mitigate their impact. A principal risk is generally considered to be an exposure that has the potential to materially impact Suncor's ability to meet or support its strategic objectives.

"The Board undertakes a comprehensive principal risk review annually and monitors the management of risk throughout the year."

Each year the Board reviews Suncor's principal risks. The Audit Committee annually reviews the governance of the ERM Program and ensures each principal risk is mapped to a Board committee or the full Board as appropriate for oversight. The Audit Committee also reviews and approves the appointment of the vice president responsible for Suncor's internal audit and enterprise risk management functions, who reports directly to the Audit Committee regarding enterprise risk management matters.

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 E-3

The following table sets forth Suncor's principal risks and the Board committee and/or full Board to which each principal risk is mapped for oversight, as well as highlighting the role of the Board and the Audit Committee in reviewing the principal risks.

Members of the Board question management at Board and committee meetings, as well as throughout the year, to ensure that risks are appropriately identified, evaluated, monitored, managed and mitigated. The high level of engagement of Board members, as well as their extensive experience, contributes to the effectiveness of the Board's risk oversight, and contributes to the Board's understanding of the interrelationship of risks and any pre-existing conditions or vulnerabilities that could have a compounding impact on Suncor.

For a detailed explanation of the significant risks applicable to Suncor and its businesses, see "Risk Factors" in Suncor's Annual Information Form dated February 25, 2016, filed at www.sedar.com.

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

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

The HR&CC reviews the succession planning process and results for executive leadership annually and reports to the Board on these matters. As part of this process, the CEO, supported by the Senior Vice President, Human Resources, reviews candidates for the CEO and other executive leadership positions with the HR&CC. In its July 2015 meeting, the HR&CC reviewed and confirmed its support for Suncor's succession and development plans for its senior executive positions.

"Effective succession planning has long been a focus of the Board. The HR&CC reviews the succession planning process and results for executive management annually."

The Board also reviews Suncor's processes for identifying successors for its vice presidents, employees who directly report to its vice presidents, and managers. Successors are identified using a formal process that rigorously assesses leadership potential across Suncor using specific criteria,

E-4 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

including employees' performance, aspirations, engagement, agility, experience and capabilities. For a discussion of how Suncor considers diversity in this process, see "Diversity" on page E-15 of this Schedule.

The Board encourages the CEO to expose the Board to Suncor's executives and high potential employees, both for succession planning and career development and to provide the Board with a broader perspective on issues relevant to Suncor. Directors are provided with opportunities to meet with Suncor employees through attendance at events hosted by Suncor, such as Suncor's President's Operational Excellence Awards, or when they visit Suncor's facilities (see "Orientation and Continuing Education" on page E-8 of this Schedule).

The HR&CC assists the Board in monitoring the CEO's performance by conducting an annual performance review against predetermined goals and criteria (including the goal of succession planning). The HR&CC also reviews with the CEO the performance of his direct reports.

Communication/Disclosure Policy and Stakeholder Feedback. Suncor has a disclosure policy that establishes guidelines 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. The Code (see "Ethical Business Conduct" on page E-9 of this Schedule) addresses Suncor's obligations for continuous and timely disclosure of material information and sets standards requiring directors, officers, employees and contract workers trading in Suncor shares and other securities to comply with applicable law.

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

Suncor interprets its operations for its shareholders and other stakeholders through a variety of channels, including its periodic financial reports, securities filings, news releases, sustainability report, webcasts, external web site, social media posts, briefing sessions and group meetings. Suncor encourages and seeks stakeholder feedback through various channels including corporate communications and investor relations programs, including surveys of shareholders and analysts, 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"), the management proxy circular, the annual information form/Form 40-F and press releases containing significant new financial information, among other items.

"Suncor encourages and seeks stakeholder feedback through various channels."

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

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

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 E-5

Expectations and Responsibilities of Directors. The Terms of Reference, supplemented by a Board approved accountability statement for directors (the "Accountability Statement"), which is available on Suncor's web site, identifies the key expectations placed on Board members. Directors are expected to review meeting materials in advance of meetings. Board meeting dates are established well in advance and directors are expected to be prepared for and attend all meetings absent extenuating circumstances. Directors' attendance records for meetings held in 2015 are set out on page E-12 of this Schedule.

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

Internal Controls. The Board is specifically mandated to ensure processes are in place to monitor and maintain the integrity of Suncor's internal controls and management information systems. The Audit Committee assists the Board in this regard and monitors the effectiveness and integrity of Suncor's financial reporting, management information, internal controls of business processes and Internal Audit function (excluding operations integrity audit matters, which are specifically within the mandate of the EHS&SD Committee(1)).

(1)
  References throughout this Schedule to "Internal Audit" in relation to the Audit Committee do not include the operations integrity audit department.

The Audit Committee exercises general oversight over the Internal Audit function by reviewing the plans, activities and performance of the Internal Auditors. The appointment or termination of the vice president responsible for Internal Audit is reviewed and approved by the Audit Committee. This individual has a direct reporting relationship with the committee and meets with it, in the absence of other members of management, at least quarterly. The Audit Committee also reviews and approves appointees to the office of the CFO.

Board Committees

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

Governance Committee. The Governance Committee assists the Board in two main areas: corporate governance; and corporate strategy.

In its governance role, the Governance Committee is mandated to determine Suncor's overall approach to governance issues and key corporate governance principles. In doing so, it closely monitors emerging best practices in governance. In addition, the Corporate Secretary, or her delegate, attends seminars, conferences and meetings on governance and updates the committee on developing trends and practices. Suncor also reviews recommendations of governance and shareholder advisory organizations and participates in benchmarking studies undertaken by such organizations to assess its governance practices in relation to those of other issuers in a wide range of geographies and industries. The Corporation's legal function monitors changes in law, administrative policy and stock exchange requirements relating to governance, and provides updates to the Governance Committee.

"The Governance Committee closely monitors emerging best practices in governance."

The committee also reviews matters pertaining to Suncor's values, beliefs and standards of ethical conduct and those principal risks that have been delegated to the committee for oversight, and assists the Board in its strategy role (see "Ethics" and "Strategic Planning", under the heading "Terms of Reference" on page E-3 of this Schedule).

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

Audit Committee. The Audit Committee assists the Board in matters relating to Suncor's external auditors and the external audit process, oil and natural gas reserves reporting, financial reporting and public communication, risk management, security and certain other key financial

E-6 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

matters. The Audit Committee also assists the Board in matters relating to internal controls of Suncor's business processes and the Internal Audit function (see "Internal Controls", under the heading "Terms of Reference" on page E-6 of this Schedule).

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

The Audit Committee reviews with management and external auditors, and as appropriate approves, significant financial reporting issues, the conduct and results of the annual audit and significant finance and accounting policies and other financial matters. The Audit Committee also reviews Suncor's annual and interim financial statements, MD&A and annual information form/Form 40-F. The committee approves interim financial statements and interim MD&A through authority delegated by the Board and makes recommendations to the Board with respect to approval of the annual disclosure documents.

The Audit Committee 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 evaluators. The Audit Committee reviews and approves the appointment and terms of engagement (including fees) of the reserves evaluators, including their qualifications and independence and any changes in their appointment. Suncor's reserves data and report of the reserves evaluator are annually reviewed by the Audit Committee prior to approval by the full Board.

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, and funding and investment strategies of Suncor's registered pension plan. The Audit Committee oversees generally the Board's risk management governance model (see "Risk Oversight", under the heading "Terms of Reference" on page E-3 of this Schedule) and also monitors components of Suncor's business conduct code compliance program (see "Ethical Business Conduct" on page E-9 of this Schedule).

Members of the Audit Committee are required to be financially literate. All of Suncor's directors, including all members of the Audit Committee, are considered 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 Messrs. O'Brien and D'Alessandro to be such experts. The criteria for assessing the financial literacy of directors, and whether they qualify as an "audit committee financial expert", are set out in the Terms of Reference in Schedule H.

For additional information about Suncor's Audit Committee, including the Audit Committee Mandate and Pre-approval Policies and Procedures, see "Audit Committee Information" in Suncor's Annual Information Form dated February 25, 2016, 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 of management's establishment and maintenance of appropriate EHS&SD policies, and monitoring the adequacy and effectiveness of OEMS and related business processes. The EHS&SD Committee also monitors management's performance and emerging trends and issues in these areas. In fulfilling its role, the EHS&SD Committee reviews management stewardship reports as well as the findings of significant external and internal environmental, health and safety investigations, assessments, reviews and audits. Suncor's annual 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 assists the Board in matters pertaining to the integrity of Suncor's physical assets, by monitoring the adequacy of Suncor's internal controls as they relate to operational risks of its physical assets and matters of environment, health, safety and sustainable development.

Human Resources and Compensation Committee. The HR&CC assists the Board by annually reviewing the performance of the CEO and recommending his total compensation to the full Board. The corporate objectives for which the CEO is responsible include a combination of corporate goals and personal goals, set annually by the Board in consultation with the HR&CC and the 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 "Compensation Discussion and Analysis" on page 26 of the Circular. See also "Succession Planning and Monitoring/Evaluating Senior Management", under the heading "Terms of Reference" on page E-4 of this Schedule.

Orientation and Continuing Education

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

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

Presentations and tours at the sites of Suncor's principal operations are provided to directors on a periodic basis, often in conjunction with Board meetings, for the purpose of directly acquainting directors with Suncor's operations and the communities in which they are located.

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

"The Board has a strategic education program and continuing education policy in place, both of which were effectively utilized in 2015."

The Board's Director Continuing Education Policy also encourages directors to enroll in courses and programs that enhance and supplement their knowledge and skills in areas relevant to their role on the Board with the approval of the Board chair or chair of the Governance Committee.

Ethical Business Conduct

Sound, ethical business practices are fundamental to Suncor's business. The Code, which applies to Suncor's directors, officers, employees and contract workers, requires strict compliance with legal requirements and sets Suncor's standards for the ethical conduct of our business. Topics addressed in the Code include competition, conflicts of interest and the protection and proper use of corporate assets and opportunities, confidentiality, disclosure of material information, trading in shares and securities, communications to the public, improper payments, harassment, fair dealing in trade relations and accounting, reporting and business control. The Code is supported by detailed policy guidance and standards and a Code compliance program, under which every Suncor director,

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 E-9

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

The Board exercises stewardship over the Code in several respects. Suncor's Internal Auditors audit the compliance program annually and the vice president responsible for Internal Audit, who has a direct reporting relationship with the Audit Committee, reports on the audit to that committee.

Moreover, at least once annually, the Code is reviewed and if appropriate, updated. Management reports to the Governance Committee annually on this process. The Governance Committee reviews any changes and ensures the Code continues to reflect Suncor's commitment to ethics and integrity, and addresses all related legal requirements and best practices. Any waivers of Code requirements for Suncor's executive officers or members of the Board must be approved by the Board or appropriate committee thereof and disclosed. No such waivers were granted in 2015.

"Suncor has adopted a business conduct code, supported by detailed guidance and standards and a code compliance program."

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

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

The Code is available on Suncor's web site.

Conflicts of Interest

The Board has 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 (regardless of the materiality of the contract or transaction), the director must immediately advise the Board chair or the particular committee chair. The director's conflict or potential conflict is recorded in the minutes of the meeting and the director is required to absent himself or herself from the meeting for any material discussions or deliberations concerning the subject matter of the contract or transaction. The director is required to abstain from voting on any resolution in respect of such contract or transaction.

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

Board and Committee Meetings

The Board chair, in consultation with the Corporate Secretary, has the responsibility of establishing a schedule for meetings of the Board and its committees each year,

E-10 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

which is approved by the Board. Board and committee meeting dates are established sufficiently in advance where possible (at least one year and longer if practical) to minimize conflict with other commitments on directors' schedules. The Board holds at least five meetings per year, one of which is devoted solely to strategy. If during the course of the year circumstances require Board or committee action or consideration, additional meetings are called.

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

The following provides details about Board and committee meetings held during 2015 and the attendance of the directors at these meetings.

Board and Committees |  | Number of Meetings Held in 2015 |
Board |  | 6 |
Audit Committee |  | 8 |

E-12 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

Nomination of Directors

The Governance Committee conducts the selection process for new nominees to the Board. The Board endeavours to be comprised of individuals representing a diversity of backgrounds, experience and skills. Directors are selected for their integrity and character, sound and independent judgment, breadth of experience, insight and knowledge and business acumen. A discussion of the Board Diversity Policy (the "Diversity Policy") and how the Board considers diversity in the selection process for nominees to the Board is found beginning on page E-15 of this Schedule.

"An ever-green list of potential board candidates is maintained and updated as needed."

Pursuant to the policies of the Board, the assessment and selection process is undertaken by the Governance Committee as needed and consists of several steps, including: (i) maintaining and updating an inventory of capabilities, competencies, skills and qualities of current Board members and of the Board as a whole; and (ii) identifying capabilities, competencies, skills and qualities desired to be added to the Board, taking pending retirements and the Board's current needs and priorities into account. The role of the CEO in that process is limited and appropriate. The Board has determined that the industry background and functional experience of the Board currently maps well to Suncor's business strategy, as well as its vision to be a trusted steward of valuable natural resources.

The table below lists the competencies of the non-executive directors standing for re-election at the annual meeting, together with their retirement dates in accordance with Suncor's Retirement and Change of Circumstance Policy (the "Retirement Policy"), assuming an annual meeting in late April of their retirement year, based on their ages.

(1)
  Dates are in accordance with Suncor's Retirement Policy and indicate the year in which the director must retire, absent exceptional circumstances. See "Mechanisms of Board Renewal" on page E-14 of this Schedule.
(2)
  Mr. Williams, the only director who is also an executive officer of Suncor, has competencies in the following areas: (i) primary industry backgrounds: technology, resources, and industrial; and (ii) functional experience: CEO experience, finance, operations, technology/IT, and corporate staff: human resources, strategy, economics
(3)
  The Board extended Mr. Simpson's term of service for one year, until the close of Suncor's 2017 annual general meeting. See "Mechanisms of Board Renewal" on page E-14 of this Schedule.

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 E-13

The above inventory is assessed as required to identify any capabilities, competencies, skills and qualities desired to be added to the Board in light of the Board's current needs and priorities. The Governance Committee uses this assessment as a basis for selection criteria describing the skills, experiences, qualifications, diversity (gender, ethnicity/Aboriginal status, age, business experience, professional expertise, personal skills, stakeholder perspectives and geographic background) and personal qualities desired in potential new Board members. The Governance Committee identifies candidates from a number of sources, including executive search firms, or referrals from existing directors. When a vacancy occurs or is pending, the Governance Committee identifies a short list of potential candidates to pursue further, considering, in addition to the factors listed above, whether each candidate can devote sufficient time and resources to his or her duties as a Board member. The Governance Committee is required to retain an executive search firm or other third party expert to assist in completing reference and background checks on Board candidates. The Governance Committee may also engage these firms and experts to assist in carrying out any of its duties in relation to recruitment. Pursuant to Board policies, the Governance Committee is required to maintain and update as needed, a list of potential Board candidates for planned and unplanned vacancies through the form of an ever-green list.

Throughout the process, the Governance Committee provides updates to the Board and solicits input on candidates. Candidates are interviewed by members of the committee and other directors as deemed appropriate. The Governance Committee ultimately provides its recommendation on Board candidates to the full Board. Candidates may be appointed by the Board to hold office for a term expiring not later than the close of the next annual meeting of shareholders.

Mechanisms of Board Renewal

The Board's goal is to be a balanced board made up of members with diverse characteristics, experience and tenure. In furtherance of that goal, the Board has implemented two primary mechanisms of board renewal: the Retirement Policy; and an annual evaluation process, each of which is described in detail below. The Board has not adopted term limits for directors, as it believes the Retirement Policy and the annual board evaluation process are effective in achieving the appropriate level of renewal of the Board's membership.

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

In 2015, in light of Suncor's business needs and the period of significant renewal the Board has experienced in recent years, which is expected to continue in the coming years as a result of retirements of directors, the Board approved an extension of the term of service of the Board chair, James W. Simpson, for one additional year, until the close of the 2017 annual general meeting.

Assessment of Directors. Suncor's Board Effectiveness Policy establishes an annual process (the "Evaluation Process") whereby directors are provided with an opportunity to evaluate the effectiveness of the Board, its committees, the Board chair, committee chairs and individual directors and to identify areas where effectiveness may be enhanced. The Evaluation Process carried out in 2015 showed that all directors and committees, and the Board as a whole, effectively fulfilled their responsibilities.

"The Board conducts an annual review process for the Board, its committees, the Board chair, the chair of each committee and its members."

The Evaluation Process involves the solicitation of input from individual directors through an annual on-line survey presented in two parts: (i) an evaluation form that explores the directors' views and solicits feedback on how well they believe the Board and its committees, including their chairs, are performing (the "Board Effectiveness Survey"); and (ii) a peer feedback survey (the "Peer Survey") that explores the directors' views and solicits feedback on their assessment of other directors' performance, including their contributions and participation in Board discussions and debate, accountability, knowledge, experience, demonstration of high ethical standards and communication and persuasion skills.

The Evaluation Process includes open-ended questions to allow directors to elaborate on their responses and to

E-14 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

suggest improvements. The Board Effectiveness Survey asks each director whether he or she believes the Board and each of its committees are functioning as they should in accordance with their mandates. Consideration of the appropriateness of the Board's size is also addressed and the size of the Board was confirmed to be appropriate by the directors in 2015. Information obtained from the answers to these questions assists the Board in determining whether any of the Board or committee mandates or Board processes or policies should be revised.

Board Effectiveness Review

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

Peer Review

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

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

Diversity

Board of Directors. A fundamental belief of Suncor's Board is that a Board comprised of women and men representing diverse points of view can add greater value than a Board comprised solely of directors with similar backgrounds. The Board aims to be comprised of directors who have a range of perspectives, insights and views in relation to the issues affecting Suncor. This belief in diversity was confirmed in the written Diversity Policy adopted by the Board. The Diversity Policy states that the Board should include individuals from diverse backgrounds, having regard to gender, ethnicity/Aboriginal status, age, business experience, professional expertise, personal skills, stakeholder perspectives and geographic background. Accordingly, consideration of whether the diverse attributes highlighted in the policy are sufficiently represented on the Board, including consideration of the number of women who are directors, is an important component of the selection process for new members of Suncor's Board.

"The Board has a written Diversity Policy."

The Board has ensured that the Diversity Policy will be effectively implemented by embedding it into its policy for the selection process for new Board members (the "Selection Process Policy"). The Selection Process Policy requires the Governance Committee to conduct periodic assessments to consider the level of representation on the Board of the various attributes enumerated in the Diversity Policy, including the number of women on the Board. The Governance Committee has emphasized the Board's commitment to the recruitment of women in recent years by making the identification of candidates who are women a key search criterion in the director selection and nomination processes it has undertaken. The Board members also have the opportunity annually to evaluate the effectiveness of the director selection and nomination process, including compliance with the Diversity Policy, through the Board's Evaluation Process.

Following the annual general meeting and assuming that all nominees for director are elected as contemplated in the Circular, four of 12 directors (33.3%) on the Board will be women. The Board recognizes the value of the contribution of members with diverse attributes on the Board and is committed to ensuring that there is significant representation of women on the Board. The Board has not, however, established a target regarding the number of women on the Board. The Board has determined that, at this time, a target would not be the most effective way of ensuring it is comprised of individuals with diverse

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 E-15

attributes and backgrounds. The Board believes its current make-up reflects the principles of diversity set out in the Diversity Policy.

Suncor Management. Suncor believes that a diversity of backgrounds, opinions and perspectives and a culture of inclusion helps to create a healthy and dynamic workplace, which improves overall business performance.

Suncor recognizes the value of ensuring that the Corporation's employees have diverse attributes, including that it has a substantial number of employees who are women. The Corporation has developed an execution plan to work towards increasing the number of employees who are women throughout the organization, including in leadership positions. One of the objectives of this plan is to ensure there will be highly qualified women within Suncor available to fill vacancies in executive officer and other leadership positions. A particular focus of this work has been to increase the representation of women in operations and maintenance roles, two areas in which women have been traditionally underrepresented in Suncor's industry.

"Suncor aims to build a culture of inclusion throughout the organization."

In appointing individuals to its senior leadership team, which is comprised of Suncor's executive officers and senior leaders reporting directly to executive officers, Suncor weighs a number of factors, including the skills and experience required for the position and the personal attributes of the candidates. The level of representation of women in senior leadership roles is also considered as one such factor.

Currently, one out of nine members (11.1%) of Suncor's executive leadership team, which is comprised of Suncor's executive officers, is a woman and 13 out of 46 (28.3%) Suncor senior leaders are women.

At the present time, Suncor has not adopted a target for the number of women in executive officer or senior leadership positions. Suncor believes the most effective way to achieve its goal of increasing the representation of women in leadership roles at all levels of the organization is to identify high-potential women within the Corporation and work with them to ensure they develop the skills, acquire the experience and have the opportunities necessary to become effective leaders. This includes regularly assessing formal processes to identify and remove barriers to women's advancement, as well as taking action to build a culture of inclusion throughout the organization. In 2016, Suncor will begin implementing a program that will focus on addressing root issues that may hinder the development of a culture of inclusion and the progression of women into leadership roles. This initiative will include training personnel to be aware of unconscious biases and a review of core human resource processes to ensure they are not influenced by systemic bias.

Suncor is committed to other aspects of diversity in addition to its initiatives to foster gender diversity. The Corporation is building a strategy aimed at increasing the participation of Aboriginal Peoples in energy development, including the goal of improving Aboriginal workforce development at Suncor.

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. Suncor is not required to and does not comply with Section 303A.08 of the NYSE Listed Company Manual which requires shareholder approval of all equity compensation plans and any material revisions thereto, regardless of whether the securities to be delivered under such plans are newly issued or purchased on the open market. The TSX rules, which Suncor complies with, only require shareholder approval for certain of Suncor's equity compensation plans in accordance with a specific amendment provision, as approved by shareholders at the 2007 annual and special meeting and by the TSX. See "Summary of Incentive Plans" on page 61 of the Circular.
•
  Independence Standards. The Board 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 the Canadian Requirements (specifically National Instrument 52-110 – Audit Committees) and SEC Requirements (specifically Rule 10A-3 under the U.S. Securities Exchange Act of 1934, as amended). The Board has not adopted, and is not required to adopt, the director independence standards contained in Section 303A.02 of the NYSE's Listed Company Manual, including with respect to its audit committee and compensation committee. The Board has not adopted, nor is it required to adopt, procedures to implement Section 303A.05(c)(iv) of the NYSE's Listed Company Manual in respect of compensation committee advisor independence.

F-2 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

SCHEDULE G: DIRECTOR INDEPENDENCE POLICY AND CRITERIA

Background:

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

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

Independence Policy:

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

Independence Criteria:

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

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

•
  The director is, or has been within the last three years, an employee or executive officer of Suncor, or an immediate family member is or has been within the last three years, an executive officer, of Suncor.
•
  The director has received, or an immediate family member has received, during any 12-month period within the last three years, more than $75,000 in direct compensation from Suncor, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service) and other than compensation received by any immediate family member for service as an employee of Suncor (other than an executive officer).
•
  The director or an immediate family member is a current partner of a firm that is Suncor's internal or external auditor; a director is a current employee of such a firm; or a director's immediate family member is a current employee of such a firm and participates in the firm's audit, assurance or tax compliance (but not tax planning) practice; or a director or an immediate family member who was within the last three years (but is no longer) a partner or employee of such a firm and personally worked on Suncor's audit within that time. For the purposes of this point ONLY, "immediate family member" means a spouse, minor child or stepchild, adult child or stepchild sharing a home with the director.
•
  The director or any immediate family member is or has been within the last three years employed, as an executive officer of another corporation where any of Suncor's current executive officers at the same time serve on that corporation's compensation committee.
•
  The director is a current employee, or an immediate family member is a current executive officer, of a corporation that has made payments to, or received payments from, Suncor, for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1 million, or 2% of such other corporation's consolidated gross revenues.
•
  Contributions to tax exempt organizations shall not be considered "payments" for the purposes of these rules, provided that Suncor shall disclose in its proxy circular such contributions made to any tax exempt organization in which a director serves as an executive officer, if within the preceding three years, contributions in any single fiscal year from Suncor to the organization exceeded the greater of $1 million, or 2% of such organization's consolidated gross reserves.

(1)
  Unless otherwise noted, "immediate family member" is defined to include a person's spouse, parents, children, siblings, mothers and fathers in law, sons and daughters in law, brothers and sisters in law, and anyone other than domestic employees who shares such person's home.

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 G-1

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

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

•
  Has previously acted as an interim CEO of Suncor; or
•
  Acts, or has previously acted, as chair or vice chair of the Board or of any Board committees on a part-time basis; or
•
  Sits on the board of directors or as a trustee or in an equivalent capacity, of another corporation, firm or other entity, which has a business relationship with Suncor, provided that the individual's remuneration from the other entity is not personally material to that individual or dependent on or variable with the nature or extent of the business relationship with Suncor, the individual is not involved in negotiating, managing, administering or approving contracts between Suncor and the other entity, and the individual otherwise is in compliance with the Board's conflict of interest policy with respect to contracts between Suncor and that other entity.

G-2 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

SCHEDULE H: BOARD TERMS OF REFERENCE

Part I: Overview

The Canada Business Corporations Act (the Act), Suncor's governing statute, provides "that the directors shall manage or supervise the management of the business and affairs of a corporation...". In practice, as a Board of Directors cannot "manage" a corporation such as Suncor 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. This responsibility is discharged through Board oversight of Suncor'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's business and affairs are managed. In this way, the Board assumes responsibility for the stewardship of the Corporation. Specific responsibilities which facilitate the discharge of the Board's stewardship responsibilities include: the strategic planning process, risk identification and management, ensuring that effective stakeholder communication policies are in place, and ensuring the integrity of internal controls and management information systems. These responsibilities, and others, are addressed in more detail in the Board's Mandate, comprising Part IV of these Terms of Reference.

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

The CEO of Suncor 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's best interests and in accordance with current standards. The Act also identifies certain matters which must be considered by the Board as a whole and may not be delegated to a committee or to management. These matters include:

•
  any submission to the shareholders of a question or matter requiring the approval of the shareholders;
•
  the filling of a vacancy among the directors or in the office of the external auditor;
•
  the manner of and terms for the issuance of securities;
•
  the declaration of dividends;
•
  the purchase, redemption or any other form of acquisition of shares issued by the Corporation;
•
  the payment of a commission to any person in consideration of the purchase or agreement to purchase shares of the Corporation from the Corporation or from any other person, or procuring or agreeing to procure purchasers for any such shares;
•
  the approval of management proxy circulars;
•
  the approval of any take-over bid circular or directors' circular;
•
  the approval of the audited annual financial statements of the Corporation; and
•
  the adoption, amendment or repeal of by-laws of the Corporation.

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

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 H-1

Part II: Board Guidelines

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

•
  These Terms of Reference for the Board of Directors (which include the Board Guidelines, Committee Guidelines, Board Mandate and Board Forward Agenda, setting out the important issues that must be addressed by the Board of Directors annually), and the mandates and forward agendas of the Board committees, constitute the charters of the Board and committees respectively, and are reviewed by the Board annually and updated as deemed appropriate. These charters are supplemented by the position descriptions for the Board Chair 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 the Corporation's annual business plan (including the annual capital budget), and in so doing endorses 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 Chair, the Chair of the committee proposing to retain outside advisors, or the Governance Committee. In exercising their approval authority, the Board Chair, 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 Governance Committee.
•
  The Board should be comprised of a majority of independent directors. The Board has defined an independent director in written independence criteria, based on definitions under applicable law(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 be no more than three inside(2) directors on the Board of Directors.
•
  The Board supports the separation of the role of Chair from the role of CEO.
•
  The Board will evaluate the performance of the CEO at least annually. The evaluation will be based on criteria which includes the performance of the business and the accomplishment of CEO's qualitative and quantitative objectives as established at the beginning of each fiscal year of the Corporation, and the creation and fostering within the Corporation of a culture of integrity.
•
  The Board Chair 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.

(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.

H-2 SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016

•
  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.
•
  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 executives 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 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. Board members should also represent a diversity of backgrounds, experience and skills. The Board has adopted a Board Diversity Policy and a Selection Process for New Members Policy, which support this principle and ensure that diversity is a consideration in director selection. The Board ultimately determines nominees that will be included in the Corporation's management proxy circular.
•
  The outgoing Chair of the Board, or in the absence of the outgoing Chair, a director elected by resolution of the Board, shall manage the process of selecting a new Chair by seeking nominations, determining the willingness of each nominee to take on the role of Chair of the Board, and preside over the selection process.
•
  Succession and management development plans will be reviewed by the Human Resources & Compensation Committee, and reported on annually to the Board.
•
  During 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 Board Chair. 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 visit a Suncor location other than Calgary. The purpose is to facilitate continual exposure of Board members to the Corporation's operations and the communities in which they are carried out.

Part III: Committee Guidelines

•
  The Board has four standing committees: the Audit Committee, the Governance Committee, the Human Resources and Compensation Committee ("HR&CC"), and the Environment, Health, Safety & Sustainable Development Committee ("EHS&SD"). From time to time the Board may create ad hoc committees to examine specific issues on behalf of the Board. Each standing 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 Board Chair, plans Board committee appointments (including the designation of a committee Chair) for recommendation to and appointment by the Board. The committees shall be reconstituted annually following the annual general meeting at which directors are elected by the shareholders of the Corporation. In accordance with the Corporation's By-laws, unless otherwise determined by resolution of the Board of Directors, a majority of the members of a committee shall constitute a quorum for meetings of committees.
•
  Each committee shall be comprised of a minimum of three and a maximum of six directors. Each committee shall have a non-member Secretary who may be a member of management of the Corporation. The Chair of each committee, in consultation with the committee Secretary, shall determine the agenda for each committee meeting.
•
  The Board supports the principle that committee Chairs should be rotated regularly while preserving continuity.
•
  Except where otherwise specified in these terms of reference or in the Corporation's By-laws, each

SUNCOR ENERGY INC. MANAGEMENT PROXY CIRCULAR 2016 H-3

committee shall have the power to determine its own rules of procedure.

•
  The Audit Committee will consist entirely of outside, independent(3) directors. In addition, all members of the Audit committee must be, in the judgment of the Board of the Directors, financially literate(4), and at least one member of the Audit Committee must be an audit committee financial expert(5).
•
  In general, Audit Committee members will not simultaneously be members of the Audit Committee of more than two other public companies, unless the Board of Directors affirmatively determines that simultaneous service on a greater number of audit committees would not impair the member's ability to effectively serve on Suncor's Audit Committee. Any such determination by the Board of Directors shall be disclosed in the Corporation's management proxy circular.
•
  The HR&CC will consist entirely of outside, independent directors.
•
  The Governance Committee shall consist entirely of outside, independent directors.
•
  The Board Chair, by standing invitation, is considered an ex-officio of the Board standing committees of which he or she is not a listed member.
•
  During 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.
